DETAILED DESCRIPTION OF THE EMBODIMENTS

Embodiments of the present disclosure will be described in detail below with reference to examples thereof as illustrated in the accompanying drawings, throughout which same or similar elements, or elements having same or similar functions, are denoted by same or similar reference numerals. The embodiments described below with reference to the drawings are illustrative only, and are intended to explain, rather than limiting, the embodiments of the present disclosure.

A window air conditioner 100 according to the embodiments of the present disclosure is described below with reference to FIG. 1 to FIG. 4.

As illustrated in FIG. 1 and FIG. 2, the window air conditioner 100 according to the embodiments of the present disclosure includes an indoor unit assembly 10 and an outdoor unit assembly 20. The indoor unit assembly 10 includes an indoor heat exchanger 11 and an indoor drain pan 12. The indoor drain pan 12 is arranged below the indoor heat exchanger 11 and configured to receive water generated by the indoor heat exchanger 11. The outdoor unit assembly 20 includes an outdoor heat exchanger 21, an outdoor fan 23, and an outdoor drain pan 22. The outdoor drain pan 22 is arranged below the outdoor heat exchanger 21 and configured to receive water generated by the outdoor heat exchanger 21.

Further, the window air conditioner 100 further includes: a sprayer device 70 having a spraying hole facing towards an air outlet side of the outdoor fan 23; and a water conveyer device in communication with the sprayer device 70 and the indoor drain pan 12. The water generated by the indoor heat exchanger 11 falls into the indoor drain pan 12. The water conveyer device can transport the water in the indoor drain pan 12 to the sprayer device 70. The water in the indoor drain pan 12 can be transformed into water mist and sprayed to the air outlet side of the outdoor fan 23 using the sprayer device 70. The water mist is blown away by the outdoor fan 23 without arranging a drainage pipe connected to a sewer pipe, which makes the unit more aesthetically favorable after mounting. In addition, during mounting, there is no need to consider a height for the sewer pipe, thereby reducing the mounting difficulty and the mounting cost.

With the window air conditioner 100 according to the embodiments of the present disclosure, by arranging the sprayer device 70 and the water conveyer device, the water in the indoor drain pan can be conveyed to the sprayer device 70 by the water conveyer device. The water can be transformed into the water mist and sprayed to the air outlet side of the outdoor fan 23 using the sprayer device 70. The water mist is blown away by the outdoor fan 23 without connecting an external drainage pipe, which makes the unit more aesthetically favorable after mounting. In addition, during mounting, there is no need to consider the height for the sewer pipe, thereby reducing the mounting difficulty and the mounting cost.

According to some embodiments of the present disclosure, the water conveyer device is also in communication with the outdoor drain pan 22. When the window air conditioner 100 is in a heating mode, the water generated by the outdoor heat exchanger 21 falls into the outdoor drain pan 22. The water conveyer device can transport the water falling into the outdoor drain pan 22 to the sprayer device 70. The sprayer device 70 can transform the water in the outdoor drain pan 22 into the water mist and spray the water mist to the air outlet side of the outdoor fan 23. The water mist is blown away by the outdoor fan 23 without connecting an external drainage pipe outdoors, which makes the unit aesthetically favorable after mounting, without a risk of falling downstairs.

When the window air conditioner 100 is in a cooling mode, the water generated by the indoor heat exchanger 11 falls into the indoor drain pan 12. The water conveyer device can covey the water in the indoor drain pan 12 to the sprayer device 70. The water in the indoor drain pan 12 can be transformed into the water mist and sprayed to the air outlet side of the outdoor fan 23 by the sprayer device 70. The water mist is blown away by the outdoor fan 23 without arranging the drainage pipe connected to the sewer pipe, which makes the unit more aesthetically favorable after mounting. In addition, during mounting, there is no need to consider the height for the sewer pipe, thereby reducing the mounting difficulty and the mounting cost.

In an exemplary embodiment of the present disclosure, a projection of the indoor heat exchanger 11 in a plane where the indoor drain pan 12 is located is located in the indoor drain pan 12, ensuring that the indoor drain pan 12 can hold water generated by the indoor heat exchanger 11.

The indoor drain pan 12 may have an extension direction consistent with that of the indoor heat exchanger 11. For example, the indoor heat exchanger 11 may have a linear structure. Correspondingly, the indoor drain pan 12 may have a linear structure corresponding to a shape of the indoor heat exchanger 11.

Similarly, a projection of the outdoor heat exchanger 21 in a plane where the outdoor drain pan 22 is located is located in the outdoor drain pan 22, ensuring that the outdoor drain pan 22 can hold water generated by the outdoor heat exchanger 21.

The outdoor heat exchanger 21 may have an extension direction consistent with that of the outdoor heat exchanger 21. For example, the outdoor heat exchanger 21 may have a U-shaped structure. Correspondingly, the outdoor water tray 24 may have a U-shaped structure or an L-shaped structure corresponding to a shape of the outdoor heat exchanger 21.

To ensure a spraying effect, the spraying hole can have a diameter ranging from 0.1 mm to 0.8 mm. For example, the spraying hole can have a diameter of 0.1 mm, 0.3 mm, 0.5 mm, 0.8 mm, or the like.

As illustrated in FIG. 1 and FIG. 2, according to some embodiments of the present disclosure, the water conveyer device includes: a first water conveying tube 31 having an end in communication with an inlet of the sprayer device 70, and another end adapted to be in communication with the outdoor drain pan 22; and a first water conveying member 32 connected to the first water conveying tube 31.

In the heating mode of the window air conditioner 100, the water generated by the outdoor heat exchanger 21 falls into the outdoor drain pan 22. The first water conveying member 32 can convey the water in the outdoor drain pan 22 to the sprayer device 70 through the first water conveying tube 31. In the cooling mode of the window air conditioner 100, the water generated by the indoor heat exchanger 11 falls into the indoor drain pan 12, and finally can be transported to the sprayer device 70 through the first water conveying tube 31. In the above two modes, the sprayer device 70 can transform the water in the outdoor drain pan 22 into the water mist and spray the water mist to the air outlet side of the outdoor fan 23. The water mist is blown away by the outdoor fan 23.

To ensure an atomization effect of water, in some embodiments, the first water conveying member 32 is a high pressure spraying water pump. When the high pressure spraying water pump is started, the water can be pressurized and delivered to the sprayer device 70. The water mist can be formed by the sprayer device 70. Apparently, the first water conveying member 32 may also be a self-priming booster pump or a water pump with a pressure-boosting structure (for example, a Venturi structure).

In some embodiments, a first filter 33 is arranged between the outdoor drain pan 22 and the first water conveying tube 31 to prevent debris in the outdoor drain pan 22 from blocking the first water conveying tube 31 or the first water conveying member 32.

When an outdoor ambient temperature is below 0° C., an electric heating tape or a hot gas bypass pipe may be used to insulate the first water conveying tube 31, the first water conveying member 32, the first filter 33, and the sprayer device 70 to prevent freezing of the first water conveying tube 31, the first water conveying member 32, the first filter 33, and the sprayer device 70. When the outdoor ambient temperature is above 0° C., it is not necessary to activate the above thermal insulation structure.

As illustrated in FIG. 1, in some embodiments, the water conveyer device further includes: a second water conveying tube 41 having an end in communication with the indoor drain pan 12, and another end extending towards the outdoor unit assembly 20; and a second water conveying member 42 connected to the second water conveying tube 41.

In the cooling mode of the window air conditioner 100, the water generated by the indoor heat exchanger 11 falls into the indoor drain pan 12. The second water conveying member 42 can guide the water in the indoor drain pan 12 towards the outdoor unit assembly 20 by the second water conveying tube 41, and then to fall into the outdoor drain pan 22. The first water conveying member 32 can convey the water in the outdoor drain pan 22 to the sprayer device 70 by the first water conveying tube 31. The sprayer device 70 can transform the water in the outdoor drain pan 22 into the water mist and spray the water mist to the air outlet side of the outdoor fan 23. The water mist is blown away by the outdoor fan 23.

In some examples, the another end of the second water conveying tube 41 is in communication with the outdoor drain pan 22. That is, the second water conveying tube 41 is in direct communication with the outdoor drain pan 22. The water in the indoor drain pan 12 is directly conveyed into the outdoor drain pan 22 using the second water conveying member 42 and the second water conveying tube 41, which makes the structure of the window air conditioner be simple, and the window air conditioner is easy to be controlled.

In other examples, an outdoor water tray 24 is arranged above the outdoor heat exchanger 21. The outdoor water tray 24 is in communication with the another end of the second water conveying tube 41.

When the window air conditioner 100 is in the cooling mode, the water generated by the indoor heat exchanger 11 falls into the indoor drain pan 12. The second water conveying member 42 can convey the water in the indoor drain pan 12 to the outdoor water tray 24.

The outdoor water tray 24 has a plurality of outdoor water outlet holes 241 through which water in the outdoor water tray 24 can flow out to guide water towards the outdoor heat exchanger 21. Since a temperature of the outdoor heat exchanger 21 is high in the cooling mode, water on the outdoor heat exchanger 21 can be evaporated.

Therefore, by arranging the outdoor water tray 24 having the plurality of outdoor water outlet holes 241, the water generated by the indoor heat exchanger 11 can be stored, in such a manner that this part of the water can fall to different parts of the outdoor heat exchanger 21 in a wider range. In this way, a contact area between the water and the outdoor heat exchanger 21 can be increased. Heat generated by the outdoor heat exchanger 21 can be fully utilized to allow the water to be evaporated by the outdoor heat exchanger 21 as much as possible.

In this process, the first water conveying member 32 can convey the water falling into the outdoor drain pan 22 to the sprayer device 70 by the first water conveying tube 31. The sprayer device 70 can transform the water in the indoor drain pan 12 into water mist and spray the water mist to the air outlet side of the outdoor fan 23. The water mist is blown away by the outdoor fan 23 without arranging the drainage pipe connected to the sewer pipe indoors, which makes the unit more aesthetically favorable after mounting. In addition, during mounting, there is no need to consider the height for the sewer pipe, thereby reducing the mounting difficulty and the mounting cost.

That is, after the second water conveying member 42 conveys the water in the indoor drain pan 12 to an outdoor side. A part of the water is evaporated through exchanging heat with the outdoor heat exchanger 21, and another part of the water falling into the outdoor drain pan 22 is conveyed to the sprayer device 70 under an action of the first water conveying member 32 and is transformed into the water mist using the sprayer device 70, and finally is discharged to the air outlet side of the outdoor fan 23.

In some embodiments, at least part of the plurality of outdoor water outlet holes 241 are arranged in the extension direction of the outdoor heat exchanger 21.

As illustrated in FIG. 3 and FIG. 4, the outdoor heat exchanger 21 includes a first heat exchanger portion, a second heat exchanger portion, and a third heat exchanger portion. The first heat exchanger portion and the third heat exchanger portion are arranged opposite to each other. The second heat exchanger portion is connected between the first heat exchanger portion and the third heat exchanger portion. That is, the outdoor heat exchanger 21 may have a U-shaped structure.

Correspondingly, the outdoor water tray 24 may have a U-shaped structure or an L-shaped structure corresponding to the shape of the outdoor heat exchanger 21. The plurality of outdoor water outlet holes 241 are arranged in the extension direction of the outdoor heat exchanger 21, in such a manner that the water in the outdoor water tray 24 can fall to different parts of the outdoor heat exchanger 21 in a wider range in the extension direction of the outdoor heat exchanger 21. The heat generated by the outdoor heat exchanger 21 can be fully utilized to allow the water to be evaporated by the outdoor heat exchanger 21 as much as possible.

In some examples, a second filter is arranged between the indoor drain pan 12 and the second water conveying tube 41 in a direction of water flow to prevent debris in the indoor drain pan 12 from blocking the second water conveying tube 41 and the second water conveying member 42. The second water conveying member 42 can be a one-way water pump. The second water conveying member 42 is arranged in the indoor drain pan 12 to ensure that all the water in the indoor drain pan 12 can be conveyed to the outdoor unit assembly 20.

As illustrated in FIG. 2, in other embodiments, a first water conveying tube 31 includes a water inlet tube segment 311 and a water outlet tube segment 312. The water inlet tube segment 311 is in communication with the outdoor drain pan 22. The water outlet tube segment 312 is in communication with a first water conveying member 32. The water conveyer device further includes a third water conveying tube 51. An end of the third water conveying tube 51 is in communication with the indoor drain pan 12. The water outlet tube segment 312 is selectively in communication with the water inlet tube segment 311 or the third water conveying tube 51.

In the heating mode, the window air conditioner 100 can control the water outlet tube segment 312 to be in communication with the water inlet tube segment 311, in such a manner that the water generated by the outdoor heat exchanger 21 falls into the outdoor drain pan 22. The first water conveying member 32 can convey the water in the outdoor drain pan 22 to the sprayer device 70 by the water inlet tube segment 311 and the water outlet tube segment 312. The sprayer device 70 can transform the water into the water mist and spray the water mist to the air outlet side of the outdoor fan 23. The water mist is blown away by the outdoor fan 23.

In the cooling mode, the window air conditioner 100 can control the water outlet tube segment 312 to be in communication with the third water conveying tube 51, in such a manner that the water generated by the indoor heat exchanger 11 falls into the indoor drain pan 12. The first water conveying member 32 can convey the water in the indoor drain pan 12 to the sprayer device 70 sequentially by the third water conveying tube 51 and the water outlet tube segment 312. The sprayer device 70 can transform the water into the water mist and spray the water mist to the air outlet side of the outdoor fan 23. The water mist is blown away by the outdoor fan 23.

In some examples, the water conveyer device further includes a switch assembly 60 having a first inlet 61, a second inlet 62, and an outlet 63. The outlet 63 is selectively in communication with the first inlet 61 or the second inlet 62. The first inlet 61 is in communication with the third water conveying tube 51. The second inlet 62 is in communication with the water inlet tube segment 311. The outlet 63 is in communication with the water outlet tube segment 312. This design is simple in structure and easy to control.

In some specific examples, the switch assembly 60 is a solenoid valve. For example, the switch assembly 60 may be a two-position three-way solenoid valve.

Apparently, the switch assembly 60 may also include two on-off valves. When one of the two on-off valves is opened and another one of the two on-off valves is closed, the outlet 63 is in communication with the first inlet 61 to allow the water outlet tube segment 312 to be in communication with the third water conveying tube 51 for water conveying in the cooling mode. When one of the two on-off valves is closed and the another one of the two on-off valves is opened, the outlet 63 is in communication with the second inlet 62 to allow the water outlet tube segment 312 to be in communication with the water inlet tube segment 311 for water conveying in the heating mode.

In some specific examples, a third filter 53 is arranged between the indoor drain pan 12 and the third water conveying tube 51 in a direction of water flow to prevent debris in the indoor drain pan 12 from blocking the third water conveying pipe 51 and the first water conveying member 32.

As illustrated in FIG. 3, according to some embodiments of the present disclosure, the window air conditioner 100 further includes a housing 80 having an indoor cavity 81 and an outdoor cavity 82 spaced apart from the indoor cavity 81. The indoor unit assembly 10 is arranged in the indoor cavity 81. The outdoor unit assembly 20 is arranged in the outdoor cavity 82.

The indoor unit assembly 10 further includes an indoor fan 13 arranged close to the indoor heat exchanger 11 to supply air to the room.

The housing 80 further has an accommodation cavity 83 in communication with the indoor cavity 81 and the outdoor cavity 82, and the water conveyer device spans the accommodation cavity 83, concealing partial structure of the water conveyer device in the accommodation cavity 83 without affecting an appearance of the window air conditioner 100.

It should be noted that the above-mentioned first filter 33, the second filter, and the third filter 53 may adopt a high-precision filter similar to a water purifier. The filter may be placed in the indoor cavity 81 to facilitate replacement of the filter. The above water conveying member can use a reversible pump. In the event of a blockage in the sprayer device 70, the water conveying member can utilize a reverse flow function to draw impurities from the sprayer device 70 back into the filter for removal.
