Description

CROSS-REFERENCE TO RELATED APPLICATION

The application is based on the Chinese patent application No. 2024116575163, filed on Nov. 19, 2024, and claims the priority of the patent application, the whole contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to the field of water heaters, in particular to a multi-system water heater module and a heat pump system.

BACKGROUND ART

In the prior hot water heater module, the water circuit system is single, and the mounting scenario is mostly wall-mounted. As shown in FIG. 1, the pipes are commonly extended out at the lower side.

DETAILED DESCRIPTION OF EMBODIMENTS

In order to make the purpose, technical solutions, and advantages of the embodiment clearer, the technical solutions of the present disclosure will be described clearly and completely as follows in conjunction with drawings. It is clear that the embodiments described are partial embodiments of the present disclosure, and not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by a person of ordinary skill in the art without inventive efforts shall fall within the scope of protection of the present disclosure.

In order to facilitate the understanding of the embodiment, the embodiment is described in detail below.

The embodiment provides a multi-system water heater module, including a boxy 23 and at least two water line systems, wherein each water circuit system is arranged in the box body 23; one of the water circuit systems is connected to a first end device; and the other water circuit system is connected to a second end device, wherein the first end device and the second end device are different.

The embodiment further provides a heat pump system, including a heat pump host, a first end device, a second end device, and the multi-system water heater module above, wherein one water circuit system in the multi-system water heater module is communicated between the heat pump host and the first end device, and the other water circuit system in the multi-system water heater module is communicated between the heat pump host and the second end device.

As shown in FIG. 2, two water circuit systems are provided, wherein one water circuit system is a first water circuit system 21; the other water circuit system is a second water circuit system 22; and the first water circuit system 21 and the second water circuit system 22 are both arranged in the box body 23, wherein the first water circuit system 21 is connected to a first end device; the second water circuit system 22 is connected to a second end device; and the first end device and the second end device are different. In practical use, the first end device is preferably a domestic water tank, and the second end device is preferably at least one of the following: an air conditioner, floor heating, and radiator groups. The specific first end device and the second end device can be arranged according to the actual situation, and the embodiment will not be described in detail herein.

The above multi-system water heater module can accommodate multiple water circuit systems, wherein each water circuit system is connected to a different end device, so as to integrate multiple water circuit systems, which meets the needs of multiple usage and mounting scenarios, wherein the mounting space is smaller, and the operation and the control are more convenient, which further improves the mounting and maintenance efficiency, so as to save the mounting cost.

In one embodiment, the water circuit system includes a cold-water pipeline and a hot-water pipeline arranged in the box body 23, and end parts of the hot-water pipeline and the cold-water pipeline both pass through a side wall of the box body 23. During use, the external cold water source or the end device transmits the cold water to the heat pump host by the cold-water pipeline, wherein the cold water undergoes the heat transfer when flowing through the heat pump host, so as to become the hot water; and then the hot water flows to the end device via the hot-water pipeline, so as to be used by the user or supply heat to the indoor environment by the end device.

The end parts of the cold-water pipeline and the hot-water pipeline are arranged on the side wall of the box body 23. In this way, it can ensure a bottom flatness of the box body 23 based on realizing the cold and hot water circulation, so that the box body 23 and the multi-system water heater module not only can be used by mounting on the wall, but also can be used on the ground, so as to meet the needs of multiple usage and mounting scenarios. Additionally, since the end part of each pipeline is located on the side wall of the box body 23 rather than the bottom, the operator can directly carry out mounting and maintaining operations at the side part of the box body 23, wherein the operation is more convenient, so as to facilitate the mounting and maintenance after sale.

In the embodiment, the hot-water pipeline is provided with a heater, a first check valve, and a water flow switch, and the first check valve is located on a water inlet side of the heater, wherein one hot-water pipeline is provided with a safety valve 226. Since the hot-water pipeline is provided with the heater, when the heat pump host supplies heat to the end device by the water circuit system, if the heat supply capacity of the heat pump host reaches the requirement, the heater can be turned off; and if the heat supply capacity of the heat pump host does not reach the requirement, the heater can be turned on and carry out auxiliary heating for the hot water flowing through the hot-water pipeline, so as to improve the temperature of the hot water sent to the end device, and thus to ensure the heat supplying effect on the end device, so that the adjustability of the heat pump system is improved, and the heat supplying effect of the heat pump system is ensured.

When the heat pump host is turned off or starts running, the first check valve can be called an unidirectional valve for preventing the hot water from returning to the heat pump host; and the water flow switch can also be called a target flow switch for detecting the fluid in the hot-water pipeline after heated by the heater, which solves problems of dry burning of the heater and excessive pressure of the water circuit system because the flow rate is too small, so as to ensure the normal operation of the water circuit system. The safety valve 226 is used to relieve pressure for the first water circuit system 21 and the second water circuit system 22, so as to protect the multi-system hot water module.

As shown in FIG. 2, the first water circuit system 21 includes a first cold-water pipeline 211 and a first hot-water pipeline 212 arranged in the box body 23, and end parts of the first hot-water pipeline 212 and the first cold-water pipeline 211 both pass through the side wall of the box body 23. Similarly, the second water circuit system 22 includes a second cold-water pipeline 221 and a second hot-water pipeline 222 arranged in the box body 23, and end parts of the second hot-water pipeline 222 and the second cold-water pipeline 221 both pass through the side wall of the box body 23.

The heater located in the first hot-water pipeline 212 is a first heater 213; the first check valve is a first check valve A214; and the water flow switch is a first water flow switch 215. The heater located in the second hot-water pipeline 222 is a second heater 223; the first check valve is a first check valve B224; the water flow switch is a second water flow switch 225; and the safety valve 226 can be arranged in the first hot-water pipeline 212 or the second hot-water pipeline 222.

As shown in FIG. 4, one cold-water pipeline is provided with a pressure gauge 26, and the pressure gauge 26 is mounted on an outer side wall of the box body 23. The pressure gauge 26 is designed to be external, which is convenient for monitoring during after sale and daily use.

In the embodiment, the cold-water pipeline is provided with a water pump and a second check valve, and the second check valve is located on a water outlet side of the water pump. Through providing the water pump, the liquid can flow in the cold-water pipeline, and the pipeline can be arranged in the hot-water pipeline less, which can reduce the damage to the water pump when the hot water flows in the hot-water pipeline, so as to accordingly ensure the stable operation of the water pump. Through providing the second check valve, it can prevent the water flow back from damaging the water pump, which plays a protective role, so as to further ensure the stable operation of the water pump.

The water pump located in the first cold-water pipeline 211 is a first water pump 216, and the second check valve is a second check valve A217; and the water pump located in the second cold-water pipeline 221 is a second water pump 227, and the second check valve is a second check valve B228.

In the embodiment, in two water circuit systems, one hot-water pipeline is provided with a three-way valve 24, and a branch connector 241 of the three-way valve is communicated with the other the hot-water pipeline by the hot-water connection pipeline 29; and a cold-water connection pipeline 25 is communicated between pipeline sections of two cold-water pipelines being located on a water inlet side of the water pump.

The hot-water connection pipeline 29 is communicated between hot water pipes of the first water circuit system 21 and the second water circuit system 22 by the three-way valve 24, so that the first water circuit system 21 and the second water circuit system 22 are connected. During the normal use, as shown in FIG. 2, by adjusting the main path of the three-way valve 24, i.e., the first end (i.e., the end A) and the second end (i.e., the end B) can pass, and the first hot-water pipeline 212 and the second hot-water pipeline 222 are operated independently. When one end device, such as the living water tank, reaches temperature, and the requirement of the other end device, such as the heating end, is too large to meet, by adjusting the three-way valve 24, the branches, i.e., the first end (i.e., the A end) and the third end (i.e., the C end) can pass, wherein the first hot-water pipeline 212 can transfer the hot water to the second hot-water pipeline 222 by the three-way valve 24, so that the first water circuit system 21 and the second water circuit system 22 provide a heat source or a cold source to the heating end together, so as to quickly satisfy the heating or cooling demand of the user. Additionally, the three-way valve 24 also facilitates the disassembly and assembly of the second water circuit system 22, wherein when the mounting scenario changes, the disassembly and assembly of the second water circuit system 22 can be directly completed by the three-way valve 24. Further, when it needs to mount three or more water circuit systems, the second water circuit system 22 can be expanded, and it only needs to add multiple valve bodies or multiple three-way valves 24 in order.

As shown in FIG. 2, a cold-water connection pipeline 25 is communicated between the first cold-water pipeline 211 and the second cold-water pipeline 221. When the flow rate of the cold water transferring to the heat pump host by the second cold-water pipeline 221 in one end device, such as the heating end, cannot reach the requirement, the other end device, such as the living water tank, can supply the flow rate of the cold water to the second cold-water pipeline 211 by the first cold-water pipeline 211 and the cold-water connection pipeline 25, so as to ensure the stable operation of each circulation system.

Specifically, as shown in FIG. 2, the three-way valve 24 is located on the water outlet side of the corresponding heater.

In the embodiment, the specific form of the cold-water connection pipeline 25 communicating with the cold-water pipeline is below. As shown in FIG. 9-FIG. 15, the multi-system water heater module further includes a three-way pipe 100, wherein the three-way pipe includes a water inlet pipeline section 110, a first water outlet pipeline section 120 and a second water outlet pipeline section 130, and a nut 150 is rotationally sleeved on an end part of the first water outlet pipeline section 120; and the water inlet pipeline section 110 is communicated with one cold-water pipeline; the nut 150 is threadedly connected to a water inlet connector of the corresponding water pump; and the second water outlet pipeline section 130 is communicated with the cold-water connection pipeline 25. Based on arranging the cold-water connection pipeline 25 by using the three-way pipe 100, the first water outlet pipeline section 120 of the three-way pipe 100 is connected to the water inlet connector of the water pump 216 through rotation by the nut 150, which is more convenient for the disassembly and assembly. It does not need to connect the water pump to the first water outlet pipeline section 120 by the connecting tube, which results in a reduction of the distance between them, so as to shorten the pipeline length of the cold-water pipeline. Further, the convenience and simplicity of the arrangement of the cold-water pipeline are correspondingly improved, and the space occupied by the cold-water pipeline in the box body 23 and the interference with the other pipeline are reduced.

Specifically, as shown in FIG. 9-FIG. 15, the three-way pipe 100 can be arranged in the first cold-water pipeline 211, and the nut 150 threadedly connected to the water inlet connector a12161 of the first water pump 216. Similarly, the cold-water connection pipeline 25 and the second cold-water pipeline 221 can be communicated by the three-way pipe 100. Specifically, the water inlet pipeline section 110 of the three-way pipe 100 is communicated with the second cold-water pipeline 221; the nut 150 is threadedly connected to the water inlet connector b12271 of the second water pump 227; and the second water outlet pipeline section 130 is communicated with the cold-water connection pipeline 25.

In the embodiment, one end of the hot-water pipeline and one end of the cold-water pipeline both pass through and are arranged on the first side wall 231 of the box body, and the other ends both pass through and are arranged on the second side wall 232 of the box body, wherein end parts of the hot-water pipeline and the cold-water pipeline located on the same side wall are staggered in a width direction of the corresponding side wall. The end parts of the cold-water pipeline and the hot-water pipeline are overall arranged on the first side wall 231 and the second side wall 232, and the other side walls of the box body 23 are in a flat state, so as to improve the flexibility of the arrangement of the box body 23 in use; and The amounts of the pipeline ports arranged around the side walls of the box body 23 are reduced, so as to avoid the condition that the occupying space for arranging the box body 23 is too large and it cannot ne arranged against a wall. The end parts of various pipelines arranged on the same side wall are arrayed from top to bottom and staggered in the width direction of the side wall, i.e., the end parts of various pipelines located on the same side wall are arranged in a non-collinear method in the vertical direction, so as to make full use of the space of each region of the side wall and the box body 23 in the width direction. The compactness of the arrangement of the pipeline is improved, so as to accordingly reduce the overall volume of the box body 23 and the multi-system water heater module, and to make it miniaturized.

For ease of illustration, in the embodiment, the port connecting the first hot-water pipeline 212, the first cold-water pipeline 211, the second hot-water pipeline 222, and the second cold-water pipeline 221 to the heat pump host (or the outdoor host) is called as the first end; and the port connecting the first hot-water pipeline 212, the first cold-water pipeline 211, and the first end device to the second hot-water pipeline 222, the second cold-water pipeline 221, and the second end device is called as the second end.

Specifically, as shown in FIG. 2 and FIG. 3, the first cold-water pipeline 211 includes a first end 2111 and a second end 2112; the first hot-water pipeline 212 includes a first end 2121 and a second end 2122; the second cold-water pipeline 221 includes a first end 2211 and a second end 2212; and the second hot-water pipeline 222 includes a first end 2221 and a second end 2222, wherein the first end 2111 of the first cold-water pipeline 211, the first end 2121 of the first hot-water pipeline 212, the first end 2211 of the second cold-water pipeline 221, and the first end 2221 of the second hot-water pipeline 222 are all passed through and arranged on the first side wall 231 of the box body 23, wherein the first side wall 231 is the left side wall of the box body 23 in the view of FIG. 2; and the second end 2112 of the first cold-water pipeline 211, the second end 2122 of the first hot-water pipeline 212, the second end 2212 of the second cold-water pipeline 221, and the second end 2222 of the second hot-water pipeline 222 are all passed through and arranged on the second side wall 232 of the box body 23, wherein the second side wall 232 is the right side wall of the box body 23 in the view of FIG. 2.

In one arrangement method, the first water circuit system 21 is located below the second water circuit system 22. In another arrangement method, the hot-water pipelines and the cold-water pipelines can be overall arranged respectively. Specifically, the first hot-water pipeline 212 of the first water circuit system 21 is located below the second hot-water pipeline 222 of the second water circuit system 22; the first cold-water pipeline 211 of the first water circuit system 21 is located below the second cold-water pipeline 221 of the second water circuit system 22; and the second cold-water pipeline 221 is located below the first hot-water pipeline 212, i.e., the first hot-water pipeline 212 and the second hot-water pipeline 222 are distributed overall; the first cold-water pipeline 211 and the second cold-water pipeline 221 are distributed overall; and the overall distributed cold-water pipelines are arranged below the overall distributed hot-water pipelines.

As shown in FIG. 9, the end part of the first cold-water pipeline 211, the end part of the first hot-water pipeline 212, the end part of the second cold-water pipeline 221, and the end part of the second hot-water pipeline 222 located on the same side wall are arranged in sequence from bottom to top, and the first cold-water pipeline 211, the second cold-water pipeline 221, and the second hot-water pipeline 222 all extend transversely between the first side wall 231 and the second side wall 232, wherein the first hot-water pipeline 212 includes a vertical pipeline section 2124 extending vertically and a transverse pipeline section 2125 extending transversely between the first side wall 231 and the second side wall 232, wherein a top end of the vertical pipeline section 2124 is communicated with one end of the transverse pipeline section 2125 towards the first side wall 231; a bottom end of the vertical pipeline section 2124 is connected to the first side wall 231 by a first connecting pipeline section 2123; one end of the transverse pipeline section 2125 towards the second side wall 232 is connected to a second side wall 232 by a second connecting pipeline section 2126, wherein the transverse pipeline section 2125 is located above the second hot-water pipeline 222.

In each water circuit system, the end part of the cold-water pipeline is located below the end part of the hot-water pipeline, wherein this arrangement is more consistent with the arrangement habit of the user to the cool and hot pipes, which facilitates the assembling and maintenance of the operator to the hot and cold pipes, and reduces the assembling error rate.

Additionally, three pipes of the first cold-water pipeline 211, the second cold-water pipeline 221, and the second hot-water pipeline 222 extend transversely and are arranged at intervals from bottom to top. The second hot-water pipeline 212 is provided with the vertical pipeline section 2124 extending vertically and the transverse pipeline section 2125 extending transversely, so as to ensure that various pipelines are arranged vertically on two ends. Further, the first cold-water pipeline 211 and the second cold-water pipeline 221 can be arranged adjacently, so as to shorten the length of the cold-water connection pipeline 25 connected between them. Further, the transverse pipeline section 2125 of the first hot-water pipeline 212 and the second hot-water pipeline 222 can be arranged adjacently, so as to shorten the length of the hot-water connection pipeline 29 connected between them. The compactness and the convenience of the arrangement of each water pipeline are correspondingly improved, and the volume and the occupying space of the multi-system water heater module are also reduced.

On the other hand, the first cold-water pipeline 211 and the second cold-water pipeline 221 are arranged adjacently and are located at the lower region of the box body 23. When the first water pump 216 is arranged on the first cold-water pipeline 211, and the second water pump 227 is arranged on the second cold-water pipeline 221, the center of the multi-system water heater module moves downwardly, so as to improve the stability of the multi-system water heater module, and accordingly to improve the stability of the floor-type placement thereof and to improve the stability of the mounting and conveyance process, which avoids the condition of the multi-system water heater module being tilted and damaged.

Further, the main pipeline section of each pipeline approximately extends in a straight-pipe shape of three horizontal and one vertical. Based on the above arrangement, it does not need to provide bending pipes with complicated shapes and occupying larger space, such as S pipe and U pipe, so as to shorten the length of the pipeline, reduce the occupying space of the pipeline, and improve the compactness of the pipeline arrangement. The above arrangement can effectively reduce the height required for the arrangement of each pipeline, so as to reduce the height of the box body, and to improve its applicability for the mounting scenarios, for example, the multi-system water heater module can be arranged below the windowsill, so as to make full use of the space below the windowsill.

It should be noted that the above “extending transversely” is not limited to the extension in the horizontal direction, and the overall up-and-down tilt angle of two ends of the pipeline being smaller than 30° also belongs to the “extending transversely” described in the present disclosure.

In the embodiment, as shown in FIG. 9-FIG. 12, the transverse pipeline section 2125 is provided with a three-way valve 24, wherein a main path between the first end (i.e., the end A) and the second end (i.e., the end B) of the three-way valve 24 is communicated to the transverse pipeline section 2125, and a branch connector 241 of the third end of the three-way valve 24 is communicated to the second hot-water pipeline 222. Since the transverse pipeline section 2125 and the second hot-water pipeline 222 both extend transversely and are arranged adjacently, the three-way valve 24 is arranged on the transverse pipeline section 2125, and is communicated between the transverse pipeline section 2125 and the second hot-water pipeline 222 by the hot-water connection pipeline 29. Therefore, two circulation systems assist each other in heating by adjusting the pathway of the three-way valve 24, so as to effectively shorten the length of the hot-water connection pipeline 29, to reduce the space occupation of the hot-water connection pipeline 29, and to improve its convenience of arrangement.

In the embodiment, as shown in FIG. 12 and FIG. 13, the multi-system water heater module further includes a first Y-connector 200 located in the box body, wherein openings of a first branch connector a1210 and a second branch connector a2220 of the first Y-connector 200 both face the first side wall 231; one end of the second hot-water pipeline 222 towards the second side wall 232 is connected to the first branch connector a1210, and a third end of the three-way valve 24 is connected to the second branch connector a2220 by the hot-water connection pipeline 29; and the first Y-connector 200 is arranged on a part close to the second side wall 232, or the third branch connector a3230 of the first Y-connector 200 is fixedly arranged on the second side wall 232.

Since the openings of the first branch connector a1210 and the second branch connector a2220 of the first Y-connector 200 both face the first side wall 231, the opening orientation of the first branch connector a1210 is consistent with the extension direction of the second hot-water pipeline 222, and they are approximately communicated in a direct insertion; and the opening orientation of the second branch connector a2220 and the orientation of the third end port of the three-way valve 24 are approximately perpendicular. The hot-water connection pipeline 29 can include a first pipeline section 291 extending in a facing direction along the third end port of the three-way valve 24 and a second pipeline section 292 extending in a facing direction along the opening of the first branch connector a1210, wherein the first pipeline section 291 is communicated with an opposite end of the second pipeline section 292 in shape of an angle; one end of the first pipeline section 291 departing from the second pipeline section 292 is communicated with the third end of the three-way valve 24 in approximate direct insertion; and one end of the second pipeline section 292 departing from the first pipeline section 291 is communicated with the second branch connector a2220 in approximate direct insertion.

Through providing the first Y-connector 200, it can improve the arrangement simplicity of the second hot-water pipeline 222 and the hot-water connection pipeline 29, which avoids the condition of pipeline bending, so as to improve the convenience of pipeline arrangement and reduce the space occupation thereof.

The arrangement corresponding to the connection between the third branch connector a3230 and the second side wall can be specifically as follows. The opening of the third branch connector a3230 faces the second side wall 232, and the third branch connector a3230 passes through and is arranged on the second side wall 232 by other pipelines; or the third branch connector a3230 extends out of the second side wall 232 proximally in a direction towards the second side wall 232.

The structure compactness of the multi-system water heater module is correspondingly improved; the volume and the occupying space are reduced; and the convenience of the arrangement of each pipeline is improved.

In the embodiment, the first cold-water pipeline 211 and the second cold-water pipeline 221 in their extension directions sequentially include a cold-water pipeline section A extending from left to right, a cold-water pipeline section B extending from front to back, and a cold-water pipeline section C extending from left to right, wherein a left end of the cold-water pipeline section A passes through and is arranged on the first side wall; a region between a rear side of the cold-water pipeline section A and a left side of the cold-water pipeline section B is an accommodation space; and a right end of the cold-water pipeline section C is connected to the second side wall by the cold-water pipeline section D, wherein the vertical pipeline section is located behind the first cold-water pipeline, the second cold-water pipeline, and the second hot-water pipeline and is accommodated in the accommodation space; and the water pump is located on the cold-water pipeline section C.
