LAUNDRY TREATING APPARATUS AND METHOD FOR CONTROLLING THE SAME

Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of Korean Patent Application No. 10-2024-0177839, filed on Dec. 3, 2024, which is hereby incorporated by reference as if fully set forth herein.

TECHNICAL FIELD

The present disclosure relates to a laundry treating apparatus and a method for controlling the same. More specifically, the present disclosure relates to a laundry treating apparatus and a method for controlling the same capable of performing a refreshing cycle such as sterilization, wrinkle removal, deodorization, and drying of laundry by supplying steam and hot air to the laundry.

BACKGROUND

A laundry treating apparatus refers to a washing machine that washes an object-to-be-treated, such as laundry, through a washing cycle, and a dryer that dries the object-to-be-treated through a drying cycle. In general, the washing machine and the dryer are able to be equipped as separate apparatuses, but there is a laundry treating apparatus capable of simultaneously performing the washing and the drying to overcome space constraints and improve user convenience.

To perform the washing cycle, the laundry treating apparatus includes a cabinet, a tub in which water is stored, a drum providing a space in which the object-to-be-treated is accommodated, a driver that is fixed to the tub and rotates the drum, a support supporting the tub, a water supply that supplies water to the tub, and a water discharger that discharges water from the tub.

In one example, to perform the drying cycle, the laundry treating apparatus includes a circulation duct that discharges air inside the tub and re-supplies the air to the tub, and a heat exchanger assembly that sequentially performs dehumidification and heating of the air.

That is, among the existing laundry treating apparatuses, there is one that installs both the apparatus for the washing cycle and the apparatus for the drying cycle inside the cabinet to selectively perform the washing cycle and the drying cycle based on user's convenience (KR 10-2022-0021611).

In the existing washer-dryer, because both the circulation duct and the heat exchanger assembly are disposed upwardly of the tub and a compressor is disposed outside the circulation duct, there is a limitation in arranging the components.

In addition, there is a problem in that a connection portion connecting the circulation duct with the tub is lengthened due to the above-described limitation in the arrangement of the components, and the connection portion is damaged by vibration of the tub.

In addition, when an inlet of the circulation duct and an outlet of the tub are arranged on the same line, the connection portion may also be arranged on the same line, so that it is necessary to fix the connection portion so as to be positioned on the same line.

In addition, as the circulation duct is coupled to the cabinet, the outlet of the tub and the connection portion may be misaligned by the vibration of the tub, so that a bracket for fixing the connection portion to the tub needs to be disposed.

In addition, when the bracket for fixing the connection portion to the tub is directly coupled to the tub, the bracket may be integrally formed with the circulation duct and be coupled to the tub. Because a volume of the circulation duct is great, the work may not be easy. Therefore, there is a need for a means capable of easily assembling the bracket to the tub.

DETAILED DESCRIPTION

Hereinafter, embodiments disclosed herein will be described in detail with reference to the accompanying drawings. In the present document, the same or similar reference numerals will be assigned to the same or similar components even in different embodiments, and a description thereof will be substituted by a first description. A singular expression used herein includes a plural expression unless the context clearly indicates otherwise. In addition, in describing the embodiments disclosed herein, when it is determined that a detailed description of the related known technology may obscure the gist of the embodiments disclosed herein, the detailed description will be omitted. In addition, it should be noted that the accompanying drawings are only for making it easy to understand the embodiments disclosed herein, and the technical idea disclosed herein should not be interpreted as being limited by the accompanying drawings.

FIG. 1 illustrates a laundry treating apparatus according to the present disclosure.

The laundry treating apparatus according to the present disclosure may include a cabinet 100 forming an outer appearance thereof, and a laundry accommodating portion 200 disposed inside the cabinet 100 to store laundry therein.

The laundry accommodating portion 200 may include a drum 220 that stores the laundry in the cabinet 100. The drum 220 may be disposed inside the cabinet 100 so as to rotate the laundry.

Alternatively, the laundry accommodating portion 200 may further include a tub 210 that stores water in the cabinet 100, and the drum 220 may be rotatably disposed in the tub 210.

The cabinet 100 may include a front panel 110 having an opening 111 defined therein and in communication with the inside of the drum 220, side panels 150 disposed on both sides of the front panel 110, and a rear panel 160 connecting rear surfaces of the side panels 150 to each other.

The front panel 110 may be formed in a plate shape, and a door 112 for opening and closing the opening may be pivotably coupled thereto.

The front panel 110 may have an interface I installed thereon that receives a user's command or displays a state of the laundry treating apparatus at a location above the opening 111. At least a portion of the interface I may be equipped as a touch panel.

The cabinet 100 may further include an installation panel 120 disposed above an opening of the drum 220 and coupled to the side panels 150 disposed at both sides of the cabinet 100.

The installation panel 120 may be constructed such that a control panel capable of receiving a command for controlling the laundry treating apparatus or displaying an operating state of the laundry treating apparatus to the outside may be mounted thereon.

The installation panel 120 may be disposed at the rear of the front panel 110, and may be coupled to an upper end of a front surface of each side panel 150.

The installation panel 120 may include a panel installation portion 121 that fixes a front side of the circulation duct 800 to be described later. The panel installation portion 121 may be defined in a groove shape in which a rear side of the circulation duct 800 is mounted, or may be defined in a hole shape through which a fastening member fastened to the rear side of the circulation duct 800 extends.

The tub 210 may be formed in a cylindrical shape, and may have a tub inlet 213 defined in a front side thereof through which the laundry is introduced. The tub inlet 213 may be in communication with the opening of the front panel 110, and may also be in communication with the inside of the drum 220.

The drum 220 may be made of a metal material and having a cylindrical shape with an open front side, and may have through-holes defined in an outer surface thereof so that water and detergent stored in the tub 210 may be introduced thereinto or discharged therefrom.

The laundry treating apparatus according to the present disclosure may further include a water supply/discharger 400 that supplies or discharges water to or from the tub 210.

The water supply/discharger 400 may include a water supply 410 that supplies water to the tub 210 and a water discharger 420 that discharges water received in the tub 210 to the outside of the cabinet 100.

The water supply 410 may include a water supply valve 411 that receives water from an external water supply source, a water supply pipe 413 that guides water supplied from the water supply valve 411 toward the tub 210, and a detergent box 412 that stores detergent therein, and receives water supplied from the water supply valve 411 and supplies the detergent to the tub 210.

The water supply valve 411 may be coupled to the rear panel 160, and may include a plurality of water supply valves as necessary to supply water as the plurality of water supply valves are selectively opened. The water supply pipe 413 may also include a plurality of water supply pipes to supply water to at least one of the detergent box 411, the tub 210, and a circulation duct 800 to be described later.

The water discharger 420 may include a water discharge pipe 421 extending from a lower portion of the tub 210 and a water discharge pump 422 that provides power for discharging water discharged from the water discharge pipe 421 to the outside of the cabinet 100.

In addition, the water supply/discharger 400 may further include a circulator 430 that allows water discharged from the water discharge pipe 421 of the water discharger 420 to be introduced into the tub 210 again.

The circulator 430 may include a circulation nozzle 431 that is coupled to the tub inlet 213 and discharges water into the tub 210, and at least one of a circulation hose and a circulation pump that supplies water discharged from the water discharge pipe 421 to the circulation nozzle 431.

A base 600 forming a bottom surface of the laundry treating apparatus according to the present disclosure may be further included. The base 600 may allow the cabinet 100 to be seated thereon and support the cabinet 100. In addition, the base 600 may support an electrical component such as the water discharge pump 421.

The laundry treating apparatus according to the present disclosure may further include a support 500 that supports the tub 210 inside the cabinet 100. The support 500 may be equipped as a plurality of suspensions, one end of each is coupled to the tub 210 and an opposite end of each is coupled to the base 600.

The laundry treating apparatus according to the present disclosure may further include the circulation duct 800 capable of circulating air inside the tub 210. The circulation duct 800 may define a flow channel for circulating air inside the drum 220 outside the tub 210. Accordingly, the laundry treating apparatus according to the present disclosure may be equipped as a washer-dryer.

Because the components such as the water discharger 420 and the support 500 are disposed under the tub 210, the circulation duct 800 may be disposed upwardly of the tub 210.

The laundry treating apparatus according to the present disclosure may further include a heat exchanger assembly 900 that heats air flowing through the circulation duct 800. The heat exchanger assembly 900 may include a heat exchanger disposed inside the circulation duct 800 and a compressor 940 that is disposed outside the circulation duct 800 and supplies a high-temperature refrigerant to the heat exchanger.

The compressor 940 may be disposed downwardly of the tub 210. Accordingly, a space in which the circulation duct 800 may be installed may be more widely secured between an upper portion of the tub 210 and the side panels 150. Therefore, in the laundry treating apparatus according to the present disclosure, the circulation duct 800 may be disposed to extend in a front-rear direction. Accordingly, the circulation duct 800 may extend in the same direction as an extension direction of the tub 210 and the drum 220, thereby not only reducing a flow channel resistance, but also uniformly supplying hot air to the inside of the drum 220.

In addition, because the compressor 940 is omitted from the space defined upwardly of the tub 210, the circulation duct 800 may be disposed to be biased toward one of both side panels 150 from an upper end of the tub 210, and a cross-sectional area of the circulation duct 800 may be expanded accordingly. Accordingly, the laundry treating apparatus according to the present disclosure may circulate a larger amount of air to the outside of the tub 210 than when the compressor 940 is disposed on top of the tub 210.

The laundry treating apparatus according to the present disclosure may further include an air circulator 1000 that is mounted in the circulation duct 800 and circulates air in the tub 210. Because the compressor 940 is not disposed on top of the tub 210, the air circulator 1000 may be disposed at a rear side of the circulation duct 800, and suck air inside the tub 210 and supply the sucked air into the circulation duct 800.

In addition, because the compressor 940 is disposed downwardly of the tub 210, the air circulator 1000 may fully utilize the space between the upper portion of the tub 210 and the side panels 150. As a result, the air circulator 1000 may be disposed such that a diameter thereof is directed in a width direction and may be disposed to rotate around a vertical rotation axis, thereby enabling circulation of a greater air flow.

As a result, in the laundry treating apparatus according to the present disclosure, as the compressor 940 is disposed downwardly of the tub 210, a larger amount of air may circulate through the circulation duct 800 per unit time, thereby increasing a drying efficiency.

FIG. 2 illustrates an arrangement state of a circulation duct and a heat exchanger assembly.

The tub 210 is formed in a cylindrical shape extending in the front-rear direction, and the cabinet 100 has an interior defined in a rectangular parallelepiped shape. Therefore, in the area defined upwardly of the tub 210, more space is secured at left and right sides than at a center O in the width direction of the cabinet 100.

The circulation duct 800 may be disposed to be biased to one of the left and right sides from the center O. That is, a center in the width direction of the circulation duct 800 may also be disposed to be spaced apart from the center O in the width direction of the cabinet to one of the left and right sides.

In this regard, a portion of the circulation duct 800 may be disposed to overlap the center O in the width direction of the cabinet in a height direction. In addition, a portion of the circulation duct 800 may be disposed to be spaced apart from the center O in the width direction of the cabinet to the other of the left and right sides. As a result, a cross-sectional area of the circulation duct 800 may be expanded.

In one example, the compressor 940 may be disposed to be biased to a side on which the circulation duct 800 is biased of the left and right sides of the center O in the width direction of the cabinet 100.

For example, the compressor 940 may be disposed under the circulation duct 800, and the circulation duct 800 and the compressor 940 may be arranged to at least partially overlap each other in the height direction.

As a result, a separation distance between the circulation duct 800 and the compressor 940 in an up-down direction may be reduced, and a length of a refrigerant pipe 950 connecting the compressor 940 with the heat exchanger disposed inside the circulation duct 800 may be reduced. Therefore, because the refrigerant pipe 950 may be maximally disposed linearly in the height direction, a flow channel resistance of the refrigerant may be reduced, and a heat loss occurring in the refrigerant pipe 950 may be minimized.

In one example, the heat exchanger assembly 900 according to the present disclosure may further include a fixing plate 960 that fixes the refrigerant pipe 950 to the rear panel 160 of the cabinet 100. The fixing plate 960 may be formed in a shape of a bracket on which at least one of a rear surface and both side surfaces of the refrigerant pipe 950 is mounted and having a height greater than a width. Accordingly, the refrigerant pipe 950 may be spaced apart from the tub 210 and supported by the fixing plate 850 and the cabinet 100, and the vibration generated from the tub 210 may be prevented from being directly transmitted to the refrigerant pipe 950, thereby enhancing durability.

As a result, all of the compressor 940, the circulation duct 800, the refrigerant pipe 950, and the fixing plate 960 may be disposed on the left side of the tub 210 or on the right side of the tub 210. Accordingly, all of the compressor 940, the circulation duct 800, the refrigerant pipe 950, and the fixing plate 960 may be easily installed, repaired, and replaced when one side panel 150 is removed.

The circulation duct 800 may include a duct body 810 in which the heat exchanger is seated, and a duct cover 820 coupled to the duct body 810 and shielding the duct body 810.

The duct body 810 may be formed in a casing shape or a duct shape with an open top surface, and the duct cover 820 may be formed in a plate shape or a casing shape corresponding to the shape of the duct body 810.

The duct body 810 may include a rear connection portion 850 connected to a rear side of the tub 210 and in communication with the tub 210, and a front connection portion 840 connected to a front side of the tub 210 and in communication with the tub 210.

The rear connection portion 850 and the front connection portion 840 may be formed in a shape of a duct or a pipe through which air may flow. The rear connection portion 850 and the front connection portion 840 may be made of an elastic material. Accordingly, even when the tub 210 vibrates, the vibration of the tub 210 may be prevented from being transmitted to the duct body 810.

In the circulation duct 800, only the front connection portion 840 and the rear connection portion 850 may be coupled to the tub 210, and the duct body 810 may be spaced apart from the tub 210. A bracket 830 fixing the rear connection portion 850 to the tub 210 to fix a position of the rear connection portion 850 may be further included.

The bracket 830 may be disposed under the duct body 810 and may be seated on the tub 210. Accordingly, even when the duct body 810 is disposed to shield an air inlet/outlet of the tub 210, because the position of the rear connection portion 850 is fixed through the bracket 830, the air inlet/outlet of the tub 210 and the duct body 810 may be easily connected to each other by the rear connection portion 850.

FIG. 3 illustrates structures of the base and the rear panel.

The base 600 may include a base body 610 supporting a weight of the laundry treating apparatus, and an installation groove 620 recessed in at least one of left and right sides of the base body 610.

The installation groove 620 may be defined to be biased to one side of the base body 610, and may be defined at a rear side of the base body 610. The installation groove 620 may define a space in which the compressor 940 is seated.

The laundry treating apparatus according to the present disclosure may further include a controller or control panel 2000 capable of controlling the electrical component disposed in the laundry treating apparatus. The circulation duct 800 may be installed upwardly of the tub 210 on one side, and a detergent box, a water storage tank, or the like may be installed on an opposite side. Accordingly, the control panel 2000 may be installed on the base body 610 and disposed downwardly of the tub 210.

The control panel 2000 may be disposed on the base body 610 to be spaced apart from the installation groove 620. For example, the control panel 2000 may be disposed to be biased to an opposite side of the base body 610. As a result, the control panel 2000 may be prevented from being exposed to heat generated from the compressor 940. In addition, because the control panel 2000 and the compressor 940 are disposed downwardly of the tub 210 on both sides, the control panel 2000 and the compressor 940 may be prevented from interfering with the tub 210.

The control panel 2000 may include an HP casing 2100 that controls the heat exchanger assembly 900 and a main PCB 2200 that is coupled to the HP casing 2100 and controls the electrical component other than the heat exchanger assembly 900. Because the HP casing 2100 has a greater volume than and generates more heat than the main PCB 2200, the control panel 2000 may include a panel fan 2300 that is coupled to one side of the HP casing 2100 and cools the HP casing 2100. In addition, the control panel 2000 may further include a noise filter 2300 capable of removing noise from a current supplied from various sensors of the laundry treating apparatus or an external power source or an electrical signal generated from the HP casing 2100 and the main PCB 2200. The noise filter 2300 may be seated on the main PCB 2200 and receive the current or transmit a current signal.

The rear panel 160 may include a panel fixing portion 161 that fixes the rear side of the circulation duct 800 at an upper portion thereof. The panel fixing portion 161 may be defined in a groove shape in which the rear side of the circulation duct 800 is mounted, or may be defined in a hole shape through which a fastening member fastened to the rear side of the circulation duct 800 extends.

FIG. 4 illustrates a structure of the tub.

The tub 210 may include a cylindrical tub body and a tub inlet 213 defined in a front side of the tub body to allow the laundry to be inserted thereinto.

A diameter of the tub inlet 213 may be smaller than a diameter of the tub body. The circulator 430 may be coupled to and fixed to an outer surface of the tub inlet 213.

The tub body may be formed by coupling a front body and a rear body to each other, or may be integrally formed.

The tub 210 may further include an air outlet 211 that is disposed at a rear side of an upper portion of the tub body and discharges air inside the tub 210, and an air inlet 212 that is disposed on top of the tub inlet 213 and allows air discharged from the circulation duct 800 to be introduced thereinto.

The air outlet 211 may be formed to be biased to one side from an upper end of the tub body. Accordingly, the air outlet 211 may extend from a position lower than the upper end of the tub body to sufficiently secure a space in which the air circulator 1000 may be installed.

The air inlet 212 may be formed at an upper end of the tub inlet 213.

The tub 210 may further include a vent 215 that is biased from the upper end of the tub body to the opposite side and is in communication with the outside, and a communication pipe 216 that allows the vent 215 to be in communication with the outside of the cabinet 100.

FIGS. 5A and 5B illustrate a state in which the circulation duct is seated on the tub.

FIG. 5A illustrates a front view of the tub, and FIG. 5B illustrates a rear view of the tub.

The circulation duct 800 may include the duct body 810 that receives air from the air outlet 211 formed at the rear side of the upper portion of the tub 210 and discharges air to the air inlet 212 formed at a front side of the upper portion of the tub 210, and the duct cover 820 coupled to an upper portion of the duct body 810 to shield the inside of the duct body 810.

The duct body 810 may extend frontwards from a rear side, and may be directed in a direction corresponding to the front-rear direction of the tub 210 and the drum 220. Accordingly, a resistance of air flowing through the laundry accommodating portion 200 and the circulation duct 800 may be reduced.

The rear connection portion 850 may connect the rear side of the duct body 810 with the air outlet 211, and the front connection portion 840 may connect the front side of the duct body 810 with the air inlet 212.

The front connection portion 840 may be formed in a rectangular duct shape or may be formed of a bellows type. One end or an upper end of the front connection portion 840 may be coupled to the duct body 810, and an opposite end or a lower end thereof may be coupled to the air inlet 212.

The rear connection portion 850 may be formed in a pipe shape or may be formed of a bellows type.

However, the rear connection portion 850 may be disposed between the duct body 810 and the tub body. Therefore, the duct body 810 may press the rear connection portion 850 to the air inlet 212 due to a weight thereof. Accordingly, the rear connection portion 850 may be constructed such that one end or an upper end thereof is coupled to or is in close contact with the duct body 810, and an opposite end or a lower end thereof is coupled to or is in close contact with the air inlet 212.

At least a portion of the air circulator 1000 may be disposed between the duct body 810 and the duct cover 820, and may be disposed closer to the rear side of the duct body 810 than to the front side thereof.

The air circulator 1000 may suck air from the air outlet 211 and supply air into the duct body 810. That is, the air circulator 1000 may supply air inside the tub 210 to the inside of the circulation duct 800 at a positive pressure.

A driver 300 that rotates the drum 220 may be coupled to the rear side of the tub 210. The driver 300 may be formed of an outer rotor type.

FIG. 6 illustrates a positional relationship between the circulation duct and the tub according to the present disclosure.

The circulation duct 800 may be made of a resin-based material, and the heat exchanger accommodated therein may be made of a metal material. Accordingly, the circulation duct 800 may be vulnerable to the vibration. In addition, because the circulation duct 800 has a great weight due to the heat exchanger, the air circulator 1000, and the like, the circulation duct 800 may vibrate at a frequency and an amplitude different from those of the vibration of the tub 210. As a result, when the circulation duct 800 is directly seated on the tub 210, the circulation duct 800 and the tub 210 may collide with each other or may be damaged in severe cases. Accordingly, the circulation duct 800 may be installed inside the cabinet 100 while maintaining a state of being spaced apart from the tub 210 by a predetermined distance.

The front connection portion 840 and the rear connection portion 850 may be coupled to the tub 210, and the duct body 810 may be disposed such that a bottom surface thereof is spaced apart from the tub 210 by a specific spacing h. The front connection portion 840 and the rear connection portion 850 may be made of an elastic material to block the vibration and noise of the tub 210 from being transmitted to the duct body 810.

FIG. 7 illustrates a detailed structural embodiment of the duct body.

The duct body 810 may include an inlet duct 811 that receives air from the air outlet 211, a fan housing 812 that extends from the inlet duct 811 and accommodates the air circulator 1000 therein, a connection duct 813 that extends frontwards from the fan housing 812, an installation duct 814 that extends frontwards from the connection duct 813 and allows the heat exchanger to be installed therein, and a discharge duct 815 that extends frontwards or downwards from the installation duct 814 and discharges air to the air inlet 212. The connection duct and the installation duct may be collectively referred to as a flow duct defining a flow channel of air that has passed through the inlet duct.

The inlet duct 811 may be disposed upwardly of the air outlet 211, and may be disposed to overlap the air outlet 211 in the height direction.

The inlet duct 811 may be formed in a pipe shape or defined in a through-hole shape, and the rear connection portion 850 may be coupled thereto.

One end or a lower end of the rear connection portion 850 may be connected to or in close contact with the air inlet 212, and an opposite end or an upper end thereof may be coupled to or in close contact with the inlet duct 811.

The fan housing 812 may be formed in a circular or tornado shape.

The fan housing 812 may be formed to have a diameter or an area size greater than that of the inlet duct 811 to secure a space in which the air circulator 1000 is installed.

The air circulator 1000 may be seated in the fan housing 812, suck air of the tub 210, and supply air to the heat exchanger.

The connection duct 813 may extend frontwards from one side of the fan housing 812. The connection duct 813 may guide a radial air flow formed by the air circulator 1000 frontwards.

The connection duct 813 may be constructed such that a cross-sectional area thereof gradually increases frontwards. Accordingly, air supplied by the air circulator 1000 may be evenly distributed while a flow rate thereof decreases.

The installation duct 814 may have a width greater than that of a front end of the connection duct 813, so that the heat exchanger may be seated therein.

The installation duct 814 may define a space in which an evaporator and a condenser to be described later are seated.

The discharge duct 815 may be formed to have a smaller diameter than the installation duct 814. The discharge duct 815 may be formed such that a width thereof decreases as it extends frontwards from the installation duct 814. A distal end of the discharge duct 815 may have an area size and a shape corresponding to those of the air inlet 212.

The discharge duct 815 may extend from the installation duct 814 such that a width thereof decreases frontwards, and may have an opening defined at a front lower portion thereof.

The duct body 810 may further include an accommodation rib 816 that partitions the fan housing 812 and the connection duct 813 and inwardly accommodates the air circulator 1000.

The accommodation rib 816 may discharge air circulating along an inner circumferential surface of the fan housing 812 frontwards. That is, the accommodation rib 816 may serve as an outlet of the fan housing 812 together with one side surface of the installation duct 813.

The laundry treating apparatus according to the present disclosure may further include a fixing portion 860 fixing front and rear sides of the circulation duct 800 to the cabinet 100 and separating the circulation duct 800 from the tub 210.

The fixing portion 860 may include a front fixing portion 861 disposed at a front side of the duct body 810 and fixed to the installation panel 120, and a rear fixing portion 862 disposed at a rear side of the duct body 810 and fixed to the rear panel 160.

For example, the front fixing portion 861 may be constructed such that a fastening member or the like may be coupled to the front side of the discharge duct 815.

In addition, the front fixing portion 861 may be formed in a protrusion shape protruding from the front side of the discharge duct 815. The front fixing portion 861 may include a plurality of front fixing portions, and the plurality of front fixing portions may be arranged at the front side of the discharge duct 815 to be spaced apart from each other in the width direction. The front fixing portion 861 may be inserted into and seated in the panel installation portion 121.

For example, the rear fixing portion 862 may be constructed such that a fastening member or the like may be coupled to a rear side of the fan housing 812.

In addition, the rear fixing portion 862 may be formed in a protrusion shape protruding from the rear side of the fan housing 812. The rear fixing portion 862 may include a plurality of rear fixing portions, and the plurality of rear fixing portions may be arranged at the rear side of the fan housing 812 to be spaced apart from each other in the width direction. The rear fixing portion 862 may be inserted into and seated in the panel fixing portion 161.

FIG. 8 illustrates an embodiment of a structure in which the duct body is in communication with the tub.

The duct body 810 may extend from the rear side to the front side of the tub while being disposed on the tub.

In addition, the duct body 810 may accommodate the air circulator 1000 therein such that a diameter of the air circulator 1000 is directed in the width direction, and may have a great width such that a cross-sectional area thereof may also be further expanded. As a result, the duct body 810 may be disposed to completely overlap in the height direction an area from an upper portion of the air outlet 211 to an upper portion of the air inlet 212.

Because the air inlet 212 is disposed on the tub inlet 213, a space in which the front connection portion 840 is installed at the front side of the tub 210 may be defined.

However, because the air outlet 211 extends upwards from the tub body, when the inlet duct 811 is disposed upwardly of the air outlet 211, a space in which the rear connection portion 850 is installed or assembled between the air outlet 211 and the inlet duct 811 may be insufficient.

Accordingly, the bracket 830 may be seated on the upper portion of the tub body and connect the rear connection portion 850 to the air outlet 211. The bracket 830 may be coupled to the upper portion of the tub body to bring a lower end of the rear connection portion 850 into close contact with the air outlet 211.

An upper end of the rear connection portion 850 may be coupled to the inlet duct 811 in a state in which the rear connection portion 850 is fixed to the bracket 830. The duct body 810 may fix a position of the rear connection portion 850 by pressing the rear connection portion 850 toward the bracket 830.

The bracket 830 may include a bracket body 831 seated on the tub body and formed in a plate shape, and a coupling hole 832 defined to extend through the bracket body. The air outlet 211 may protrude upwards from one side of the tub body, the coupling hole may be disposed to be spaced upwardly apart from the air outlet, and the bracket body may be formed in the plate shape extending in the width direction so as to be seated on a top surface of the tub body.

FIG. 9 illustrates an internal configuration of the circulation duct.

The air circulator 1000 may be disposed upwardly of the inlet duct 811.

The air circulator 1000 may include an impeller 1100 that is accommodated in the fan housing 812 and introduces air inside the tub body thereinto, a fan motor 1200 that is seated outside the duct cover 820 and provides power for rotating the impeller 1100, and a rotation shaft 1300 that extends through the duct cover 820 and connects the fan motor 1200 with the impeller 1100.

The heat exchanger assembly 900 may include an evaporator 910 seated in the installation duct 814 and a condenser 920 spaced apart from the evaporator 910 toward the discharge duct 815.

The evaporator 910 may be disposed rearwardly of the condenser 920 and may be disposed closer to the air circulator 1000, and the condenser 920 may be connected to the compressor 940 through the refrigerant pipe 950 and receive a high-temperature refrigerant.

When the fan motor 1200 rotates the impeller 1100, air inside the tub 210 may be introduced into the inlet duct 811 (No. 1). Air introduced into the introduction duct 811 may be introduced into the installation duct 814 along the connection duct 813 while rotating radially by the impeller 1100. Air introduced into the installation duct 814 may be cooled to condense moisture thereof while passing through the evaporator 910, and may be heated while passing through the condenser 920 (No. 2).

Air that has passed through the condenser 920 may be discharged to the discharge duct 815 and discharged to the air inlet 212 (No. 3).

This process may be continuously performed to dry the laundry accommodated in the drum 220.

FIGS. 10A and 10B illustrate an internal structure of the circulation duct.

Referring to FIG. 10A, a diameter w2 of the fan housing 812 may be greater than half a width w1 of the installation duct. Accordingly, as illustrated in FIG. 10B, the impeller 1100 may be disposed to rotate about the vertical rotation shaft 1300. As a result, a greater amount of air inside the tub 210 may be introduced into the duct body 810 strongly without a loss.

That is, a diameter R of the impeller 1100 may be greater than a thickness H thereof, and the impeller 1100 may be accommodated inside the fan housing 812 such that the diameter R thereof is directed in the width direction, and may be accommodated such that the thickness H thereof is directed in the up-down direction.

Referring to FIG. 10A, because of the accommodation rib 816, a width W3 of a rear side or an inlet of the connection duct 813 may be smaller than the width W1 of the installation duct, and may also be smaller than the diameter W2 of the fan housing 812. In addition, the connection duct 813 may be constructed such that the width thereof gradually increases in a direction toward the evaporator 810.

Accordingly, the connection duct 813 may serve as a diffuser that evenly distributes air supplied from the fan housing 812 in the width direction frontwards.

The laundry treating apparatus according to the present disclosure may further include a nozzle 3000 capable of washing the evaporator 910 by spraying water to the evaporator 910.

The nozzle 3000 may receive water from the water supply 410 and spray water to the evaporator 910. The nozzle 3000 may be disposed to extend in the width direction of the evaporator 910 so as to supply water to an entire rear surface of the evaporator 910.

The circulation duct 800 may discharge water condensed by the evaporator 910 and water sprayed to the evaporator 910 to the water discharger 420 or the tub 210 again.

The rear surface of the evaporator 910 corresponds to an area that is first exposed to air introduced from the tub 210. Accordingly, the nozzle 3000 may spray water at a rear side of the evaporator 910 to remove foreign substances from the rear surface of the evaporator 910.

FIG. 11 illustrates a structure of supplying water to the circulation duct.

The nozzle 3000 may be disposed between a lower portion of the duct cover 820 and the evaporator 910.

The water supply 410 may include the water supply pipe 413 connected to the water supply valve 411 to supply water to the nozzle 3000.

The water supply pipe 413 may include a plurality of water supply pipes, and the plurality of water supply pipes may extend from the water supply valve 411 toward both ends of the nozzle 3000. Accordingly, water may be evenly supplied to the entire nozzle 3000 in the width direction.

FIG. 12 is a front view illustrating a state in which the front panel is removed.

Referring to FIG. 12, the tub inlet 213 may be defined in the front side of the tub 210, and the air inlet 212 may be disposed on a center of an upper portion of the tub inlet.

On the other hand, the air outlet 211 may be disposed to be biased to one side at the rear side of the tub 210.

In addition, the circulation duct 800 may be disposed upwardly of the tub 210 and fixed to the installation panel 120. The circulation duct may be disposed upwardly of the tub 210 and be biased to one side where the air outlet 212 is disposed, and the circulation duct may have a width greater than half the width of the tub. That is, the circulation duct may invade the center of the tub from one side of the tub.

In one example, the air inlet 212 and the discharge duct 815 may be connected to each other by a front connection portion 840 to be described later, and the air outlet 211 and the fan housing 812 may be connected to each other by a rear connection portion 850 to be described later.

Referring to FIG. 12, the installation duct 814 in which the heat exchanger 910 and 920 is installed may be disposed on the tub 210 and extend from one side of the tub 210 to pass a center of the tub. That is, a width D2 of the installation duct may be greater than half a width D1 of the tub.

Accordingly, a flow rate of air passing through the flow duct 813 and 814 may be secured, thereby improving the drying efficiency.

FIG. 13 illustrates an arrangement of the discharge duct and the air inlet.

The air inlet 212 may be disposed on a center of the upper end of the tub inlet 213, and the discharge duct 815 may be disposed to at least partially overlap the air inlet.

Accordingly, a flow channel of air introduced from the discharge duct to the air inlet is defined in a form close to a straight line, thereby minimizing the flow channel resistance.

FIG. 14 illustrates an arrangement of the inlet duct and the air outlet.

The air outlet 211, which is disposed at the rear side of the tub 210 to be biased to one side and discharges air inside the tub therethrough, may be included, and the air outlet may be disposed to at least partially overlap the inlet duct 811.

Accordingly, a flow channel of air introduced from the air outlet 211 to the inlet duct 811 may be defined in a form close to a straight line, thereby minimizing the flow channel resistance.

FIG. 15 illustrates positions where the circulation duct and the heat exchanger assembly are disposed.

The circulation duct 800 may be disposed such that the inlet duct 811 is disposed on a rear side, the discharge duct 815 is disposed on a front side, and the flow duct 813 and 814 connects the inlet duct and the discharge duct to each other, thereby being disposed upwardly of the tub to be directed in the front-rear direction. In addition, because the compressor is located downwardly of the tub 210, the circulation duct may be disposed upwardly of the tub and directed in the front-rear direction, and may be biased toward one side of the cabinet 100.

In one example, the air circulator 1000 may be disposed at the rear side of the circulation duct 800, the fan housing 812 may be disposed inside the duct body 810, and the fan motor 1200 may be coupled to a top surface of the duct cover 820 so that the rotation shaft 1300 may extend through the duct cover and be coupled to the circulation fan. That is, the rotation shaft may be perpendicular to the ground. Accordingly, the impeller may rotate to move air to the rear side of the circulation duct. Referring to FIG. 12, the impeller may rotate counterclockwise to move air to the rear side of the circulation duct.

In one example, the refrigerant pipe 950 may be at least partially spaced apart from the tub 210, and may be disposed so as not to overlap the tub in the front-rear direction. That is, the compressor 940 may be disposed at a rear portion of one side of the base body 610, and the refrigerant pipe may extend from the compressor along the side panel of the cabinet 100 to a vertical level at which the heat exchanger assembly 900 is disposed and then extend frontwards toward the heat exchanger assembly.

In one example, the air inlet 212 may be disposed on the tub inlet 213 so as to be located at a center thereof. Because the air outlet 211 is disposed to be biased to one side of the tub 210, air discharged to one side of the tub may be introduced and circulated to the center of the tub, and thus, air may be evenly distributed, thereby improving the drying efficiency.

In one example, the compressor 940 may be located downwardly of the tub 210, and at least a portion thereof may be disposed to be spaced apart from the circulation duct 800 so as not to overlap the same in the up-down direction. That is, the compressor may be disposed closer to one side surface of the cabinet than to the circulation duct.

In other words, because the compressor 940 is exposed outwardly of the tub 210, the refrigerant pipe 950 extending from the compressor may vertically extend upwards at a location between one side surface of the cabinet and the tub without bypassing the tub, thereby making it easy to connect the compressor, the evaporator 910, and the condenser 920 to each other.

The fan housing 812 and the impeller 1100 may be disposed upwardly of the inlet duct, bottom surfaces of the fan housing and the impeller may be disposed downwardly of bottom surfaces of the evaporator 910, the condenser 920, and the installation duct 814, and a top surface of the fan housing may be disposed upwardly of top surfaces of the evaporator 910, the condenser 920, and the installation duct. Because there is a vertical level difference between the top surfaces of the fan housing and the installation duct, the refrigerant pipe may extend from above the fan housing toward the installation duct without bypassing. Accordingly, a flow channel of the refrigerant pipe may be simplified, so that an efficiency of the refrigerant may be improved.

FIG. 16 illustrates a top view of the circulation duct.

Referring to FIG. 16, the fan motor 1200 may have a width smaller than the width of the fan housing 812, and thus the refrigerant pipe may extend from above the fan housing to a space in which the fan motor is not disposed. In other words, the refrigerant pipe may be disposed to overlap the fan motor in the left-right direction and may extend through a space defined on one side of the fan motor.

That is, the refrigerant pipe 950 may extend vertically upwards from the compressor 940, and may extend frontwards at a vertical level corresponding to an upper end of the evaporator 910 (higher than the impeller and the fan housing), thereby simplifying the flow channel of the refrigerant pipe and increasing the efficiency of the refrigerant.

In addition, a center of the flow duct 813 and 814 may be disposed closer to a center of the tub inlet 213 than a center of the fan housing 812. That is, a distance D3 from the center of the flow duct to the one side surface of the cabinet may be greater than a distance D4 from the center of the fan housing to the one side surface of the cabinet. Accordingly, a flow channel of air discharged from the tub may be formed in a streamlined shape, thereby reducing the flow channel resistance.

FIG. 17 illustrates an embodiment in which the bracket is disposed downwardly of the circulation duct.

Referring to FIG. 17, the bracket 830 may include a fastening hole 8316 extending through the bracket body 831 and coupled to the top surface of the tub.

As described above, at least a portion of the bracket 830 may be disposed between the tub 210 and the circulation duct 800, and the bracket body 831 may extend up to a position where the fastening hole 8316 is disposed so as not to overlap the circulation duct in the up-down direction. For example, as illustrated in FIG. 11, the bracket body may extend in a rod shape, and the fastening hole may be defined at a distal end thereof. As a result, because the fastening hole is exposed, installation by the operator may be facilitated, and the bracket may be replaced or repaired even without removing the circulation duct 800.

In one example, the bracket body 831 may extend from the coupling hole 8316 in a plurality of prongs, and each fastening hole may be defined at a distal end of each of the plurality of prongs, so that a plurality of fastening holes may be defined. Accordingly, a coupling force between the tub 210 and the bracket 830 may be improved.

FIGS. 18 and 19 illustrate an embodiment in which the bracket is disposed downwardly of the circulation duct.

Referring to FIGS. 18 and 19, the duct body 810 may include a through-hole 817 extending therethrough in a thickness direction to distribute the flow channel, and the bracket body 831 may extend such that the fastening hole 8316 is defined at a position corresponding to the through-hole.

As illustrated in FIG. 17, the bracket body 831 may extend in the rod shape so that the fastening hole 8316 is defined at the position corresponding to the through-hole 817, but as illustrated in FIGS. 15 and 16, the bracket body 831 may extend in the plate shape so that the fastening hole is defined at the position corresponding to the through-hole. Because the fastening hole is exposed to the outside by the through-hole, it may be easy for the operator to couple the bracket 830 and the tub 210 to each other.

In one example, the through-hole 817 may be defined in an area in which the air flow inside the circulation duct is concentrated so as not to interfere with the flow inside the circulation duct 800.

Referring to FIG. 18, the impeller 1100 may rotate counterclockwise such that air flows to the rear side of the circulation duct 800, and air may flow counterclockwise so as to flow to the connection duct. In this case, because the air flow is concentrated on a left side of the impeller 1100, the through-hole 817 may be defined to be spaced apart from the impeller to the left side. Because the air flow is distributed by the through-hole in the area where the air flow is concentrated, the flow of air may be smoothly maintained.

In addition, the through-hole 817 may extend in a longitudinal direction of the flow channel and have an outer circumferential surface formed in a streamlined shape. Accordingly, the flow channel resistance may be reduced and the flow of air may be smoothly maintained, thereby preventing a decrease in a thermal efficiency by the through-hole.

On the other hand, the through-hole 817 may be defined by utilizing a section with a low air flow.

Referring to FIG. 18, a flow channel adjacent to the impeller 1100 may be formed with a curved surface, and a vortex may be generated by the curved surface. Because the air flow is lower in an area in which the vortex is generated, when the through-hole 817 is defined in this area, the fastening hole 8316 may be exposed without interfering with the flow of air.

FIG. 20 illustrates an embodiment of a coupling structure in which the bracket is coupled to an upper end of the air outlet.

Referring to FIG. 20, the bracket 830 may include the coupling hole 832 coupled to a lower end of the rear connection portion and allowing the air outlet to be in communication with the rear connection portion, and the bracket body 831 extending outwards from an outer circumferential surface of the coupling hole, and may include a support 880 fixed to the tub 210 to support the bracket. In addition, the bracket may include a fixing portion 8317 formed to couple the bracket and the support to each other.

The coupling hole 832 may be formed as a ring having a shape corresponding to a cross-section of the air outlet 211, the bracket body 831 may be formed in a plate shape protruding outwards from the outer circumferential surface of the coupling hole, and the fixing portion 8317 may include a fixing rib formed in a rib shape protruding outwards from the bracket body.

In one example, the circulation duct 800, the rear connection portion 850, and the bracket 830 may be integrally formed. Accordingly, assembly may be completed by fixing the circulation duct to the cabinet 100 and coupling the bracket to the support 880 in an assembly process, thereby making the work easy.

The bracket 830 may be coupled to the support 880 and allow the rear connection portion 850 to be in communication with the circulation duct 800 and the air outlet 211.

The support 880 may be fixed in position such that the bracket 830 is coupled with the tub 210 at an accurate position. When the support fixes a position of the bracket, the bracket and the tub may be coupled to each other by the fastening member.

Referring to FIG. 20, the support 880 may be disposed on an outer circumferential surface of the tub 210. The support may be coupled to the outer circumferential surface of the tub at a position spaced apart from the air outlet 211, and the bracket may be inserted into and coupled to the support at a location between the air outlet and the support.

The fixing portion 8317 may include a fixing rib 83171 in a form of a protrusion protruding from the bracket body 831 outwards, and the support 880 may include a support body 881 fixed to the tub, and a guide groove 882 defined in a form of a groove protruding inwardly of the support body such that the bracket 830 rotates and the fixing rib moves by a predetermined distance.

The guide groove 882 may be defined to have a length corresponding to a predetermined distance from an inner side of the support body 881. When the bracket 830 rotates and the fixing rib 83171 moves along the guide groove by the predetermined distance, a movement of the bracket may be blocked such that the bracket no longer rotates, and the bracket may be directed in a direction to be coupled to the tub 210.

That is, the bracket body 831 may include the fastening hole 8316 coupled to the tub 210, the tub may include a tub fastening hole 217 defined in a shape corresponding to the fastening hole and coupled to the fastening hole by the fastening member, and the bracket may rotate such that the fastening hole is defined at a position corresponding to the tub fastening hole by the fixing rib 8317 and the guide groove 882.

FIG. 21 illustrates an embodiment of a coupling structure in which the bracket is coupled to the upper end of the air outlet.

Referring to FIG. 21, the support 880 may include the support body 881 seated on the air outlet 211 and allowing the air outlet and the coupling hole 832 to be in communication with each other, and a guide rib 883 protruding upwardly of the support body and having a groove defined in an outer circumferential surface thereof to protrude inwards. Further, the fixing portion 8317 may include a bent rib 83172 disposed on the bracket body 831 and bent to be engaged with the guide rib. The bent rib may be constructed to be engaged with the guide rib as the bracket body is seated on the support body and rotates, thereby fixing the bracket to the support. That is, because the support body may be constructed to be coupled to the tub, the bracket and the tub may be coupled to each other.

Multiple guide ribs 883 may be spaced apart from each other and multiple bent ribs 83172 may be spaced apart from each other, and a separation distance between the guide ribs and a separation distance between the bent ribs may be the same.

FIG. 22 illustrates an embodiment of a coupling structure in which the bracket is coupled to the upper end of the air outlet.

The support 880 may include the support body 881 seated on the air outlet 211 and allowing the air outlet and the coupling hole 832 to be in communication with each other, a support coupling body 885 protruding upwards in a shape corresponding to a shape of the air outlet from a top surface of the support body, and a support groove 884 protruding upwards in a shape corresponding to a shape of a portion of the support coupling body and protruding outwards from an inner circumferential surface thereof. Further, the bracket body 831 may be constructed to be engaged with the support groove, the fixing portion 8317 may include a coupling rib 83172 protruding downwards from the bracket body, and the coupling rib may be coupled to the support coupling body. For example, the coupling rib and the support coupling body may be coupled to each other by the fastening member.

Referring to FIG. 22, the support groove 884 may be defined at one side of the support coupling body 885, the bracket 830 may be inserted into the support groove at an opposite side, and the coupling rib 83172 and the support coupling body 885 may be coupled to each other by the fastening member.

The present disclosure may be modified and implemented in various forms, so that the scope of the rights thereof is not limited to the above-described embodiments. Therefore, when the modified embodiment includes the elements of the claims of the present disclosure, it should be regarded as belonging to the scope of the present disclosure.
