[0042] The following disclosure provides many different embodiments or examples for implementing different structures of the present utility model. To simplify the disclosure of the present utility model, components and settings of specific examples are described below. Of course, they are merely examples and are not intended to limit the present utility model.

[0043] Next, with reference to the accompanying drawings, a window air conditioner 100 according to an embodiment of the present utility model will be described.

[0044] As Figure 1 shown, the window air conditioner 100 includes an outdoor unit component 1 and an indoor unit component 2. Exemplarily, when the window air conditioner 100 is installed in a household, the window air conditioner 100 is passed through a window for installation, wherein the outdoor unit component 1 is located on the outdoor side and the indoor unit component 2 is located on the indoor side. For example, the outdoor unit component 1 and the indoor unit component 2 can be jointly arranged in the same housing; or, for another example, the outdoor unit component 1 and the indoor unit component 2 respectively have different housings, the housing of the indoor unit component 2 and the housing of the outdoor unit component 1 are arranged at intervals, and the housing of the indoor unit component 2 and the housing of the outdoor unit component 1 are connected by a connecting component 3 passing through the window. Exemplarily, the connecting component 3 can be telescopic along the interval direction between the indoor unit component 2 and the outdoor unit component 1 to adjust the distance between the outdoor unit component 1 and the indoor unit component 2 to adapt to different wall thicknesses. Exemplarily, the connecting component 3 can be rotatably connected to the outdoor unit component 1, and the outdoor unit component 1 is rotatable relative to the connecting component 3 to facilitate the installation of the outdoor unit component 1 in the window.

[0045] As Figure 1 shown, the outdoor unit component 1 includes an outdoor heat exchanger 11, and the indoor unit component 2 includes an indoor heat exchanger 21. Exemplarily, the window air conditioner 100 further includes a compressor and a reversing valve. The indoor heat exchanger 21, the outdoor heat exchanger 11, the compressor and the reversing valve participate in forming a refrigerant circulation system, and the reversing valve is used to switch between a cooling mode and a heating mode. In the cooling mode, the indoor heat exchanger 21 is at a low temperature to lower the indoor temperature, and the outdoor heat exchanger 11 is at a high temperature to dissipate heat to the outside. In the heating mode, the indoor heat exchanger 21 is at a high temperature to raise the indoor temperature, and the outdoor heat exchanger 11 is at a low temperature to absorb heat from the outside. Exemplarily, the outdoor unit component 1 further includes an outdoor fan 13 to improve the heat exchange efficiency of the outdoor heat exchanger 11, and the indoor unit component 2 further includes an indoor fan 23 to improve the heat exchange efficiency of the indoor heat exchanger 21.

[0046] As Figure 1As shown, the external unit 1 also includes a first water recovery container 12. For example, the first water recovery container 12 is used to recover the condensed water generated by the external unit 1. Exemplarily, the first water recovery container 12 includes an outdoor water receiving tray, and the outdoor water receiving tray is arranged below the outdoor heat exchanger 11. In the heating mode, due to the low temperature of the outdoor heat exchanger 11, it is easy to form water such as condensed water on the outdoor heat exchanger 11, and the water formed on the outdoor heat exchanger 11 flows downward into the outdoor water receiving tray. Of course, in addition to the condensed water that can be formed on the outdoor heat exchanger 11, there is also the possibility of forming condensed water on other components. The first water recovery container 12 can be provided with a corresponding water receiving tray to receive the condensed water at the corresponding position. In addition, the first water recovery container 12 can also include an outdoor outflow box, which gathers all the water received by the outdoor water receiving tray and the like into the outdoor outflow box, so as to facilitate the centralized treatment of all the water collected by the first water recovery container 12 here.

[0047] like Figure 1 As shown, the internal machine part 2 also includes a second water recovery container 22, for example, the second water recovery container 22 is used to recover the condensed water generated by the internal machine part 2. Exemplarily, the second water recovery container 22 includes an indoor water receiving tray, and the indoor water receiving tray is arranged below the indoor heat exchanger 21. In the cooling mode, due to the low temperature of the indoor heat exchanger 21, it is easy to form water such as condensed water on the indoor heat exchanger 21, and the water formed on the indoor heat exchanger 21 flows downward into the indoor water receiving tray. Of course, in addition to the condensed water that can be formed on the indoor heat exchanger 21, there is also the possibility of forming condensed water on other components. The second water recovery container 22 can be provided with a corresponding water receiving tray to receive the condensed water at the corresponding position. In addition, the second water recovery container 22 can also include an indoor junction box, which gathers all the water received by the indoor water receiving tray and the like into the indoor junction box, so as to facilitate the centralized treatment of all the water collected by the second water recovery container 22 here.

[0048] like Figure 1 As shown, the window air conditioner 100 also includes a water treatment system, which includes a drain pump 41, a booster pump 42, a spray pump 43 and a spray head 44. The drain pump 41 is used to transport the water collected in the first water recovery container 12 to the second water recovery container 22, the booster pump 42 is used to transport the water collected in the second water recovery container 22 to the spray pump 43, and the spray pump 43 is used to supply water to the spray head 44 so that the spray head 44 sprays, and the spray head 44 is arranged on the external unit component 1.

[0049] In the statement "The drain pump 41 is used to convey the water collected by the first water recovery container 12 to the second water recovery container 22", it is only required that the drain pump 41 can pump away the water collected by the first water recovery container 12 and convey it to the second water recovery container 22. It is not necessary for the inlet of the drain pump 41 to be directly connected to the first water recovery container 12. That is to say, the inlet of the drain pump 41 can be directly or indirectly connected to the first water recovery container 12. For example, the inlet of the drain pump 41 directly extends into the first water recovery container 12 to achieve direct connection. Or, for another example, the water treatment system further includes a third filtration device 47, and the inlet of the drain pump 41 is indirectly connected to the first water recovery container 12 through the third filtration device 47. When the drain pump 41 pumps water, the water pumped away from the first water recovery container 12 is first filtered by the third filtration device 47 and then flows through the drain pump 41 to the second water recovery container 22 to achieve indirect connection. In addition, when the drain pump 41 conveys water to the second water recovery container 22, it is not necessary for the outlet of the drain pump 41 to be directly connected to the second water recovery container 22. That is to say, the outlet of the drain pump 41 can be directly or indirectly connected to the second water recovery container 22. For example, the outlet of the drain pump 41 directly extends into the second water recovery container 22 to achieve direct connection. Or, for another example, the outlet of the drain pump 41 extends to the indoor heat exchanger 21, waters the indoor heat exchanger 21 first, and then flows from the indoor heat exchanger 21 to the water recovery container to achieve indirect connection. In short, as long as the water collected by the first water recovery container 12 can be pumped by the drain pump 41 and conveyed to the second water recovery container 22 through the drain pump 41, it is sufficient.

[0050] In the statement "The booster pump 42 is used to convey the water collected by the second water recovery container 22 to the spray pump 43", it is sufficient for the booster pump 42 to be able to draw away the water collected by the second water recovery container 22 and convey it to the spray pump 43. It is not required that the inlet of the booster pump 42 must be directly connected to the second water recovery container 22. That is to say, the inlet of the booster pump 42 can be directly or indirectly connected to the second water recovery container 22. For example, the inlet of the booster pump 42 directly extends into the second water recovery container 22 to achieve direct connection. Or, for another example, the water treatment system further includes a first filtering device 45, and the inlet of the booster pump 42 is indirectly connected to the second water recovery container 22 through the first filtering device 45. When the booster pump 42 pumps water, the water drawn away from the second water recovery container 22 first passes through the first filtering device 45 for filtration and then flows to the spray pump 43 through the booster pump 42, thereby achieving indirect connection. In addition, for the booster pump 42 to be able to convey water to the spray pump 43, it is not required that the outlet of the booster pump 42 must be directly connected to the inlet of the spray pump 43. That is to say, the outlet of the booster pump 42 can be directly or indirectly connected to the inlet of the spray pump 43. For example, the outlet of the booster pump 42 directly supplies water to the inlet of the spray pump 43 to achieve direct connection. Or, for another example, the water treatment system further includes a second filtering device 46, and the outlet of the booster pump 42 is indirectly connected to the inlet of the spray pump 43 through the second filtering device 46. When the booster pump 42 drains water, it first passes through the second filtering device 46 for filtration and then flows to the spray pump 43, thereby achieving indirect connection. In short, as long as it can be realized that the water collected by the second water recovery container 22 can be pumped by the booster pump 42 and conveyed to the spray pump 43 through the booster pump 42, it is acceptable.

[0051] In addition, the "water collected by the second water recovery container 22" is different in different modes. For example, in the refrigeration mode, it can be the condensed water flowing down from the indoor heat exchanger 21, while in the heating mode, it can be the condensed water conveyed from the first water recovery container 12 to the second water recovery container 22. Therefore, the sources of the water drawn by the booster pump 42 from the second water recovery container 22 are different in different modes.

[0052] In the statement "The spray pump 43 is used to supply water to the spray head 44 so that the spray head 44 sprays outward", the structure of the spray head 44 is not limited. For example, the spray head 44 can be a high-pressure spray head 44 with spray holes, and the water supplied by the spray pump 43 to the spray head 44 is ejected from the spray holes to form water mist. In the statement "The spray head 44 is provided on the outdoor unit component 1", the installation position of the spray head 44 in the outdoor unit component 1 is not limited. For example, the spray holes can be exposed outside the housing of the outdoor unit component 1, and the water mist is sprayed towards the outside and dissipated in the outdoor air. Or, for another example, the spray holes can spray towards the outdoor heat exchanger 11, etc.

[0053] In this way, in the cooling mode, when the water collected in the second water recovery container 22 reaches the set water level value, the booster pump 42 and the spray pump 43 can be turned on to convey the water collected in the second water recovery container 22 to the spray head 44 to atomize and spray the water, thereby solving the problem of water accumulation in the second water recovery container 22. In the heating mode, on the one hand, when the water collected in the first water recovery container 12 reaches the set water level value, the drain pump 41 can be turned on to convey the water collected in the first water recovery container 12 to the second water recovery container 22. On the other hand, when the water collected in the second water recovery container 22 reaches the set water level value, the booster pump 42 and the spray pump 43 can be turned on to convey the water collected in the second water recovery container 22 to the spray head 44 to atomize and spray the water, thereby solving the problem of water accumulation in the first water recovery container 12.

[0054] Thus, for the window air conditioner 100 according to the embodiment of the present utility model, by setting the above-mentioned water treatment system, the problem of water accumulation in the corresponding water recovery container can be solved whether in the heating mode or in the cooling mode. Moreover, by serially arranging the booster pump 42 upstream of the spray pump 43, the booster pump 42 can play an auxiliary boosting role to prevent the problem that the booster pump 42 cannot suck water due to air leakage or other reasons. And when one of the spray pump 43 and the booster pump 42 is damaged, the other can still work normally, enabling the water treatment to proceed smoothly to more reliably solve the problem of water accumulation in the water recovery container. In addition, the water treatment system of the embodiment of the present utility model is simple, requires fewer water pumps, occupies less space, has a lower cost, requires fewer interfaces on the electronic control board, has a simple control logic, and can reduce the failure rate of the water pumps and the control circuit, thereby further improving the reliability of solving the problem of water accumulation in the water recovery container.

[0055] Exemplarily, as Figure 1 shown, the drain pump 41 can be arranged in the outdoor unit component 1. The drain pump 41 can be an AC centrifugal pump, that is, a water pump operated by high-voltage alternating current, without electronic components, can withstand high temperatures, and is suitable for application in the outdoor environment. Of course, the present application is not limited thereto. According to other design requirements, the drain pump 41 can also be arranged in the indoor unit component 2. In addition, other types of water pumps can also be selected as the drain pump 41 according to needs, which is not limited here.

[0056] Exemplarily, as Figure 1 shown, the booster pump 42 can be arranged in the indoor unit component 2. For example, a DC centrifugal pump can be used, which has a good boosting effect, operates with low-voltage direct current, has electronic components, is small in size and low in noise, and is suitable for application in the indoor environment. Of course, the present application is not limited thereto. According to other design requirements, the booster pump 42 can also be arranged in the outdoor unit component 1. In addition, other types of water pumps can also be selected as the booster pump 42 according to needs, which is not limited here.

[0057] Exemplarily, as Figure 1 shown, the spray pump 43 can be provided in the indoor unit component 2. For example, a diaphragm pump can be used, which has a relatively high working head and can enable the spray head 44 to achieve a better spraying effect and reduce the probability of water droplets being sprayed out. Of course, the present application is not limited thereto. According to other design requirements, the spray pump 43 can also be provided in the outdoor unit component 1. In addition, other types of water pumps can be selected as the spray pump 43 according to needs, which is not limited here.

[0058] In some embodiments of the present utility model, as Figure 1 shown, the water treatment system further includes: a first filtering device 45, and the first filtering device 45 is provided on the water absorption path of the booster pump 42, that is, upstream of the booster pump 42 along the water flow direction, so that the booster pump 42 can extract the water treated by the first filtering device 45. It can be understood that "upstream" and "downstream" herein refer to the sequence along the water flow path. Upstream is the position where the water arrives first, and downstream is the position where the water arrives later.

[0059] Thus, by providing the first filtering device 45, the water collected by the second water recovery container 22 can first pass through the filtration of the first filtering device 45 and then be extracted by the booster pump 42, thereby improving the cleanliness of the water extracted by the booster pump 42. In this way, the spray pump 43 and the spray head 44 provided downstream of the booster pump 42 can be protected to a certain extent, the problem of the spray head 44 being clogged and not spraying can be improved, and the working reliability of the water treatment system can be enhanced.

[0060] The relative arrangement manner of the first filtering device 45 and the booster pump 42 is not limited. For example, the first filtering device 45 can include a pre-filter of the booster pump 42 surrounding the inlet of the booster pump 42. The booster pump 42 and the pre-filter of the booster pump 42 are placed in the second water recovery container 22, such as an indoor converging box. Before the water enters the booster pump 42, it must first pass through the filtration of the pre-filter of the booster pump 42. Therefore, the pre-filter of the booster pump 42 is located upstream of the booster pump 42. For another example, the second water recovery container 22 includes a first water chamber and a second water chamber. The first filtering device 45 can suck the water in the first water chamber, discharge it after treatment to the second water chamber, and the inlet of the booster pump 42 is provided in the second water chamber to extract the water treated by the first filtering device 45, which is equivalent to the first filtering device 45 being located upstream of the booster pump 42.

[0061] Exemplarily, as Figure 1 shown, the first filtering device 45 is provided in the indoor unit component 2, which is convenient for the first filtering device 45 to treat the water collected by the second water recovery container 22. Exemplarily, the first filtering device 45 is provided in the second water recovery container 22, which is beneficial for the first filtering device 45 to more directly treat the water collected in the second water recovery container 22.

[0062] Exemplarily, the first filtering device 45 includes a multi-stage filter. For example, the first filtering device 45 includes a primary filter 451 and a secondary filter 452. The water collected by the second water recovery container 22 is first filtered by the primary filter 451, and the water filtered by the primary filter 451 is then filtered by the secondary filter 452. The water filtered by the secondary filter 452 is then pumped by the booster pump 42. Exemplarily, in this embodiment, the secondary filter 452 may include the pre-filter of the booster pump 42 surrounding the inlet of the booster pump 42, and is placed together with the booster pump 42 in the second water recovery container 22, such as an indoor manifold box.

[0063] For another example, the first filtering device 45 includes a primary filter 451, a secondary filter 452 and a tertiary filter. The water collected by the second water recovery container 22 is first filtered by the primary filter 451, and the water filtered by the primary filter 451 is then filtered by the secondary filter 452. The water filtered by the secondary filter 452 is then filtered by the tertiary filter. The water filtered by the tertiary filter is then pumped by the booster pump 42. Exemplarily, in this embodiment, the tertiary filter may include the pre-filter of the booster pump 42 surrounding the inlet of the booster pump 42. By analogy, the scenario where the first filtering device 45 includes more stages of filters can be understood, which will not be elaborated here.

[0064] In some embodiments of the present application, as Figure 1 shown, the drain pump 41 drains water towards the water inlet path of the first filtering device 45, so that the water transported by the drain pump 41 to the second water recovery container 22 is processed by the first filtering device 45. For example, the drain pump 41 drains water towards the primary filter 451. In this way, the water transported by the drain pump 41 to the second water recovery container 22 can be processed by the first filtering device 45, and then pumped by the booster pump 42 and the water supply pump 52, which is beneficial to simplifying the system and improving the cleanliness of the water pumped by the booster pump 42 and the water supply pump 52.

[0065] In some embodiments of the present application, as Figure 1 shown, the water treatment system further includes: a second filtering device 46, which is arranged on the water supply path from the booster pump 42 to the spray pump 43, that is, between the booster pump 42 and the spray pump 43 along the water flow direction, so that the spray pump 43 pumps the water processed by the second filtering device 46.

[0066] Thus, by setting the second filtering device 46, the water transported by the booster pump 42 can first pass through the filtration of the second filtering device 46 and then reach the spray pump 43, thereby improving the cleanliness of the water pumped by the spray pump 43 and the booster pump 42. This can protect the spray head 44 downstream of the spray pump 43 to a certain extent, improve the problem of blockage and non-spraying of the spray head 44, and improve the working reliability of the water treatment system.

[0067] The relative arrangement of the second filtering device 46 with respect to the booster pump 42 and the spray pump 43 is not limited. For example, the inlet of the second filtering device 46 can be connected to the outlet of the booster pump 42 through a water pipe, and the outlet of the second filtering device 46 can be connected to the inlet of the spray pump 43 through a water pipe. For another example, the inlet of the second filtering device 46 can be connected to the outlet of the booster pump 42 through a water pipe, and the outlet of the second filtering device 46 and the inlet of the spray pump 43 can jointly extend into the same water box, so that the spray pump 43 can suck the water filtered by the second filtering device 46.

[0068] Exemplarily, as Figure 1 shown, when the water treatment system includes both the above-mentioned first filtering device 45 and the above-mentioned second filtering device 46 at the same time, the filtering accuracy of the first filtering device 45 can be greater than that of the second filtering device 46. The filtering accuracy can be understood as the maximum particle aperture size allowed to pass through the filter screen in front of the booster pump 42, and is usually measured in micrometers. Then, by setting the filtering accuracy of the first filtering device 45 to be greater than that of the second filtering device 46, it means that the maximum particle aperture allowed to pass through the first filtering device 45 is larger than that of the second filtering device 46. The first filtering device 45 is a coarse filter relative to the second filtering device 46, and the second filtering device 46 is a fine filter relative to the first filtering device 45. In this way, it can filter layer by layer from coarse to fine, more reliably protect the spray pump 43 and the spray head 44, more effectively improve the problem that the spray head 44 is clogged and does not spray, and improve the working reliability of the water treatment system.

[0069] Exemplarily, as Figure 1 shown, the second filtering device 46 is provided in the indoor unit component 2 and is a detachable and washable filtering device, so that the second filtering device 46 can be disassembled and washed from the indoor side, improving the protection effect of the second filtering device 46 on the spray pump 43 and the spray head 44. The "detachable and washable filtering device" means that the second filtering device 46 can be removed from the installation position, or the second filtering device 46 itself can be disassembled to achieve the purpose of cleaning. After disassembly and washing, the second filtering device 46 can be restored to restore its function.

[0070] Exemplarily, as Figure 1 shown, both the booster pump 42 and the spray pump 43 are provided in the indoor unit component 2, so that the booster pump 42 and the spray pump 43 are located on the indoor side. The indoor environment is friendly, which is beneficial to protecting the booster pump 42 and the spray pump 43.

[0071] Exemplarily, the booster pump 42 is a DC centrifugal pump, and the spray pump 43 is a DC diaphragm pump. Among them, the DC centrifugal pump has a good boosting effect, operates with low-voltage direct current, has electronic components, is small in size and low in noise, and is suitable for indoor environments. The DC diaphragm pump has a relatively high working head, which can enable the spray head 44 to achieve a better spraying effect and reduce the probability of water droplets being sprayed out. Thus, by connecting the DC centrifugal pump and the DC diaphragm pump in series, a more reliable spraying effect can be achieved, and the water accumulation problem can be solved more effectively and reliably.

[0072] Exemplarily, the booster pump 42, the second filtering device 46, and the spray pump 43 are all arranged in the indoor unit component 2, which facilitates the connection of the three.

[0073] In some embodiments of the present invention, the water treatment system further includes: a third filtering device 47, which is arranged on the water suction path of the drain pump 41, that is, upstream of the drain pump 41 along the water flow direction, so that the drain pump 41 pumps the water treated by the third filtering device 47.

[0074] Thus, by setting the third filtering device 47, the water collected in the first water recovery container 12 can first be filtered by the third filtering device 47 and then pumped by the drain pump 41. Thereby, the cleanliness of the water pumped by the drain pump 41 can be improved, enabling the drain pump 41 to transport relatively clean water to the second water recovery container 22. Subsequently, when the booster pump 42 pumps the water collected in the second water recovery container 22, to a certain extent, it protects the booster pump 42, as well as the spray pump 43 and the spray head 44 downstream of the booster pump 42, improves the problem of the spray head 44 being clogged and not spraying, and enhances the working reliability of the water treatment system.

[0075] The relative arrangement of the third filtering device 47 and the drain pump 41 is not limited. For example, the third filtering device 47 may include a pre-filter of the drain pump 41 that surrounds the inlet of the drain pump 41. The drain pump 41 and the pre-filter of the drain pump 41 are placed in an outdoor recovery container, such as an outdoor convergence box. Before the water enters the drain pump 41, it must first pass through the filtration of the pre-filter of the drain pump 41. Therefore, the pre-filter of the drain pump 41 is located upstream of the drain pump 41. Another example is that the first water recovery container 12 includes a third water chamber and a fourth water chamber. The third filtering device 47 can suck the water in the third water chamber, discharge it after treatment to the fourth water chamber, and the inlet of the drain pump 41 is arranged in the fourth water chamber to pump the water treated by the third filtering device 47, which is equivalent to the third filtering device 47 being located upstream of the drain pump 41.

[0076] In some embodiments of the present invention, such as Figure 1As shown, the drain pump 41 and the third filtering device 47 are both provided in the outdoor unit component 1, and the drain pump 41 is an AC centrifugal pump. Thus, it is convenient for the relative arrangement or connection of the drain pump 41 and the third filtering device 47. Moreover, since the drain pump 41 is an AC centrifugal pump, that is, a water pump operating with high-voltage alternating current, without electronic components, it can withstand high temperatures and is suitable for application in outdoor environments. The AC centrifugal pump can more reliably transport the water in the first water recovery container 12 to the second water recovery container 22, thereby improving the working reliability of the water treatment system.

[0077] In some embodiments of the present utility model, as Figure 1 shown, the water treatment system further includes: a water application assembly 51 and a water application pump 52. The water application assembly 51 is used for applying water to the indoor heat exchanger 21, and the water application pump 52 is used for transporting the water collected by the second water recovery container 22 to the water application assembly 51. Among them, as described above, the "water collected by the second water recovery container 22" is different in different modes. For example, in the cooling mode, it can be the condensed water flowing down from the indoor heat exchanger 21, while in the heating mode, it can be the condensed water transported from the first water recovery container 12 to the second water recovery container 22. Therefore, the water extracted by the booster pump 42 from the second water recovery container 22 has different sources in different modes.

[0078] Thus, by providing the water application assembly 51 and the water application pump 52, for example, when humidification is required, the water application pump 52 can be turned on. The water application pump 52 transports the water collected by the second water recovery container 22 to the water application assembly 51, and the water application assembly 51 applies water to the indoor heat exchanger 21. As a result, the air flowing through the indoor heat exchanger 21 can be combined with the water, and when this part of the air flow blows into the indoor environment, the indoor environment can be humidified. Another example is that in the heating mode, if the spray head 44 freezes or becomes dirty and blocked, the water application pump 52 transports the water collected by the second water recovery container 22 to the water application assembly 51, and the water application assembly 51 applies water to the indoor heat exchanger 21 to consume the water collected by the second water recovery container 22 and solve the problem of water accumulation in the second water recovery container 22.

[0079] Among them, the composition of the water application assembly 51 is not limited. For example, it can be a water spraying box provided at the top of the indoor heat exchanger 21, or a water wheel for spraying water onto the indoor heat exchanger 21, or a spray head for spraying water onto the indoor heat exchanger 21, etc. In short, anything that can apply water to the indoor heat exchanger 21 is acceptable.

[0080] In some embodiments of the present utility model, as Figure 1 shown, the water treatment system further includes: a fourth filtering device 53. The fourth filtering device 53 is provided on the water absorption path of the water application pump 52, that is, upstream of the water application pump 52 along the water flow direction, so that the water application pump 52 extracts the water processed by the fourth filtering device 53.

[0081] Thus, by providing the fourth filtering device 53, the water collected by the second water recovery container 22 can be filtered by the fourth filtering device 53 first and then pumped by the water application pump 52, thereby improving the cleanliness of the water pumped by the water application pump 52. This can protect the water application assembly 51 and the indoor heat exchanger 21 to a certain extent, improve the problem of the water application assembly 51 being clogged and not applying water, and enhance the working reliability of the water treatment system.

[0082] Exemplarily, the fourth filtering device 53 and the first filtering device 45 described above can be the same one, or can be separately provided, or the fourth filtering device 53 can also be a part of the first filtering device 45. For example, when the first filtering device 45 and the fourth filtering device 53 are the same one, the shared filtering device can be used to filter the water collected by the second water recovery container 22, and both the booster pump 42 and the water application pump 52 pump the water filtered by the shared filtering device. For another example, when the first filtering device 45 and the fourth filtering device 53 are separately provided, the first filtering device 45 can include a pre-filter screen of the booster pump 42 surrounding the inlet of the booster pump 42, and the fourth filtering device 53 can include a pre-filter screen of the water application pump 52 surrounding the inlet of the water application pump 52.

[0083] For still another example, when the fourth filtering device 53 can also be a part of the first filtering device 45, exemplarily, the first filtering device 45 includes a primary filter 451 such as a pre-filter screen and a secondary filter 452 such as a pre-filter screen of the booster pump 42. The primary filter 451 is provided upstream of the secondary filter 452, or in other words, the primary filter 451 is provided on the water inlet path of the secondary filter 452, and the secondary filter 452 is provided on the water suction path of the booster pump 42, so that the booster pump 42 pumps the water that has been processed by the primary filter 451 and the secondary filter 452 in sequence. The primary filter 451 constitutes the fourth filtering device 53 and is provided on the water suction path of the water application pump 52, so that the water application pump 52 pumps the water processed by the primary filter 451. That is to say, the first filtering device 45 can include a pre-filter screen of the booster pump 42 surrounding the inlet of the booster pump 42 and a pre-filter screen provided upstream of the pre-filter screen of the booster pump 42. This pre-filter screen can be used as the fourth filtering device 53. That is, for the water processed by the pre-filter screen, a part of it is pumped by the booster pump 42 after passing through the pre-filter screen of the booster pump 42, and the rest is directly pumped by the water application pump 52. Thus, the design can be simplified and the application of components can be reduced.

[0084] In some embodiments of the present utility model, when the water treatment system includes the above-mentioned first filtering device 45, the drainage pump 41 drains water towards the water inlet path of the first filtering device 45. For example, the drainage pump 41 drains water towards the water inlet path of the primary filter 451, so that the drainage pump 41 conveys the water treated by the primary filter 451 to the second water recovery container 22. In this way, the water conveyed by the drainage pump 41 to the second water recovery container 22 can be treated by the primary filter 451 and then pumped by the water application pump 52, which is beneficial to simplifying the system and improving the cleanliness of the water pumped by the water application pump 52.

[0085] In some embodiments of the present utility model, as Figure 1 shown, the first water recovery container 12 includes an outdoor water receiving tray disposed below the outdoor heat exchanger 11 of the outdoor unit component 1, and an outdoor converging box disposed on the side of the outdoor heat exchanger 11. The outdoor converging box is communicated with the outdoor water receiving tray, and the drainage pump 41 is disposed in the outdoor converging box to suck water from the outdoor converging box. For example, when the water treatment system includes the third filtering device 47, the third filtering device 47 can also be disposed in the outdoor converging box, and the drainage pump 41 can suck water from the third filtering device 47 in the outdoor converging box; the second water recovery container 22 includes an indoor water receiving tray disposed below the indoor heat exchanger 21 of the indoor unit component 2, and an indoor converging box disposed on the side of the indoor heat exchanger 21. The indoor converging box is communicated with the indoor water receiving tray, and the drainage pump 41 drains water to the indoor converging box through a pipeline. The booster pump 42 is disposed in the indoor converging box to suck water from the indoor converging box. For example, when the water treatment system includes the first filtering device 45, the first filtering device 45 can also be disposed in the indoor converging box, and the booster pump 42 can suck water from the first filtering device 45 in the indoor converging box. Thus, it is convenient for the centralized installation and maintenance of the water treatment system and is also convenient for the connection of water pipes and the like.

[0086] For example, when the user stands facing the window air conditioner 100 after the installation is completed at the entrance, the left and right directions of the user are the left and right directions of the window air conditioner 100. In this orientation, the side of the outdoor heat exchanger 11 can be the left side or the right side of the outdoor heat exchanger 11, and the side of the indoor heat exchanger 21 can be the left side or the right side of the indoor heat exchanger 21.

[0087] In some embodiments of the present utility model, as Figure 1As shown, an outdoor water collection box is provided with an outdoor high and low water level switch, and an indoor water collection box is provided with an indoor high and low water level switch. Both the outdoor high and low water level switch and the indoor high and low water level switch are electrically connected to the water treatment system. Among them, the outdoor high and low water level switch has a high water level and a low water level to determine whether the water level in the outdoor water collection box reaches the low water level. If it reaches the low water level, the booster pump 42 and the spray pump 43 can be turned on. If it reaches the high water level, protection should be activated, such as turning off the compressor. The indoor high and low water level switch has a high water level and a low water level to determine whether the water level in the indoor water collection box reaches the low water level. If it reaches the low water level, the drain pump 41 can be turned on. If it reaches the high water level, protection should be activated, such as turning off the compressor.

[0088] In the above technical solution, by setting an outdoor high and low water level switch in the outdoor water collection box and an indoor high and low water level switch in the indoor water collection box, and both the outdoor high and low water level switch and the indoor high and low water level switch are electrically connected to the water treatment system, the corresponding water pumps can be turned on at low water levels to avoid waste of electric energy and noise interference. At high water levels, a protection program can be executed, such as turning off the compressor, to avoid the risk of water overflowing due to too high a water level.

[0089] In some embodiments of the present utility model, as Figure 1 shown, the outer shell of the outdoor unit component 1 has a perforation, and the spray holes of the spray head 44 are exposed through the perforation to spray towards the outside. Thus, accumulated water can be consumed more efficiently, and the spray does not need to be recycled for secondary spraying.

[0090] Next, with reference to Figure 1 , a window air conditioner 100 according to a specific embodiment of the present utility model will be described.

[0091] The water treatment system includes three water pumps: a drain pump 41, a booster pump 42, and a spray pump 43. The outdoor unit component 1 is provided with a drain pump 41 (such as a 115V AC centrifugal water pump), and the indoor unit component 2 is provided with a booster pump 42 (such as a 12V DC centrifugal water pump) and a spray pump 43 (such as a 12V DC diaphragm pump). The booster pump 42 plays an auxiliary boosting role and can effectively prevent the diaphragm pump from not sucking water due to air leakage. The water treatment system is also equipped with a first filter device 45, a second filter device 46, and a third filter device 47. When the accumulated water on the outdoor side is transported to the indoor side by the drain pump 41 and is pumped by the booster pump 42 and the spray pump 43 on the indoor side and supplied to be sprayed out by the outdoor spray head 44, the outdoor unit component 1 is provided with a third filter device 47 for primary filtration, and the indoor unit component 2 is provided with a first filter device 45 and a second filter device 46 for further sequential filtration, which can effectively improve the problem of blockage of the spray pump 43 and the spray head 44.

[0092] In the refrigeration mode, with reference to Figure 1Single-arrow route: When the water level in the second water recovery container 22 reaches a certain level (for example, when the high-low water level switch installed in the second water recovery container 22 reaches the low water level), the booster pump 42 and the spray pump 43 are turned on. The condensed water recovered by the second water recovery container 22 directly goes from the first filtration device 45 to the booster pump 42, then through the second filtration device 46 to the spray pump 43, and then is supplied by the spray pump 43 to the spray head 44. The spray head 44 atomizes the indoor condensed water recovered by the second water recovery container 22 in the form of a spray and discharges it out of the window through the nozzle, avoiding the accumulation of condensed water. In the cooling mode, the outdoor temperature is relatively high, and there is no freezing situation of the spray head 44.

[0093] In the heating mode, refer to Figure 1 The double-arrow route in the figure: When the water level in the first water recovery container 12 reaches a certain level (for example, when the high-low water level switch installed in the first water recovery container 12 reaches the low water level), the drain pump 41 is turned on. The drain pump 41 conveys the outdoor condensed water processed by the third filtration device 47 into the room. At the same time, when the water level in the second water recovery container 22 reaches a certain level (for example, when the high-low water level switch installed in the second water recovery container 22 reaches the low water level), the booster pump 42 and the spray pump 43 are turned on. The condensed water recovered by the second water recovery container 22 directly goes from the first filtration device 45 to the booster pump 42, then through the second filtration device 46 to the spray pump 43, and then is supplied by the spray pump 43 to the spray head 44. The spray head 44 atomizes the indoor condensed water recovered by the second water recovery container 22 in the form of a spray and discharges it out of the window through the nozzle, avoiding the accumulation of condensed water.

[0094] In this embodiment, by setting multiple filtration devices, dirt such as sediment is filtered through multiple stages, which can effectively improve the problem of blockage of the spray pump 43 and the spray head 44. Moreover, by adding a booster pump 42 in front of the spray pump 43 for boosting function to supply water to the spray pump 43, the problem that the spray pump 43 cannot suck water due to air extraction and air leakage is solved.

[0095] Next, refer to Figure 2 to describe the window air conditioner 100 according to a specific embodiment of the present invention.

[0096] The water treatment system includes four water pumps: a drainage pump 41, a booster pump 42, a spray pump 43, and a water application pump 52. The outdoor unit component 1 is provided with the drainage pump 41 (such as a 115V AC centrifugal water pump), and the indoor unit component 2 is provided with the booster pump 42 (such as a 12V DC centrifugal water pump) and the spray pump 43 (such as a 12V DC diaphragm pump). The indoor unit component 2 is also provided with the water application pump 52 (such as a 12V DC water pump) for supplying water to the water application assembly 51, so that the water application assembly 51 adds water to the indoor heat exchanger 21. The water treatment system is also equipped with a first filter device 45, a second filter device 46, and a third filter device 47. When the accumulated water on the outdoor side is transported to the indoor side by the drainage pump 41 and extracted by the booster pump 42 and the spray pump 43 on the indoor side for spraying out through the outdoor spray head 44, the outdoor unit component 1 is provided with the third filter device 47 for primary filtration, and the indoor unit component 2 is provided with the first filter device 45 and the second filter device 46 for further sequential filtration, which can effectively improve the problem of blockage of the spray pump 43 and the spray head 44.

[0097] In the cooling mode, referring to Figure 2 the single-arrow route in the figure, when the water level in the second water recovery container 22 reaches a certain level (for example, when the high and low water level switch set in the second water recovery container 22 reaches the low water level), the booster pump 42 and the spray pump 43 are turned on. The condensed water recovered by the second water recovery container 22 directly goes from the first filter device 45 to the booster pump 42, then through the second filter device 46 to the spray pump 43, and then is supplied by the spray pump 43 to the spray head 44. The spray head 44 atomizes the indoor condensed water recovered by the second water recovery container 22 in the form of spray and discharges it out of the window, avoiding the accumulation of condensed water. In the cooling mode, the outdoor temperature is relatively high, and there is no freezing situation of the spray head 44.

[0098] In the heating mode, referring to Figure 2 the double-arrow route in the figure, when the water level in the first water recovery container 12 reaches a certain level (for example, when the high and low water level switch set in the first water recovery container 12 reaches the low water level), the drainage pump 41 is turned on. The drainage pump 41 transports the outdoor condensed water treated by the third filter device 47 indoors. At the same time, when the water level in the second water recovery container 22 reaches a certain level (for example, when the high and low water level switch set in the second water recovery container 22 reaches the low water level), the booster pump 42 and the spray pump 43 are turned on. The condensed water recovered by the second water recovery container 22 directly goes from the first filter device 45 to the booster pump 42, then through the second filter device 46 to the spray pump 43, and then is supplied by the spray pump 43 to the spray head 44. The spray head 44 atomizes the indoor condensed water recovered by the second water recovery container 22 in the form of spray and discharges it out of the window, avoiding the accumulation of condensed water.

[0099] In the humidification mode, the water application pump 52 can be turned on to convey the water pumped by the drain pump 41 to the indoor area. The water is then conveyed to the water application assembly 51 via the water application pump 52 and applied to the indoor heat exchanger 21 by the water application assembly 51, thereby humidifying the indoor heat exchanger 21. As a result, the air discharged from the indoor unit component 2 contains water vapor, which humidifies the indoor area.

[0100] In addition, in the heating mode, when the outdoor temperature is relatively low, if no anti-freezing device is set, there is a risk of the spray head 44 freezing. In this embodiment, when the outdoor temperature is lower than the set temperature value (for example, below 10°C or below 4°C), the booster pump 42 and the spray pump 43 can be turned off, and the water application pump 52 can be turned on to convey the water pumped by the drain pump 41 to the indoor area. The water is then conveyed to the water application assembly 51 via the water application pump 52 and applied to the indoor heat exchanger 21 by the water application assembly 51, thereby consuming the outdoor condensate. Of course, at this time, it also has the function of humidification.

[0101] In this embodiment, by setting a multi-stage filtration device, dirt such as sediment is filtered through multiple stages, which can effectively improve the problem of blockage of the spray pump 43 and the spray head 44. Moreover, by adding a booster pump 42 in front of the spray pump 43 for boosting function to supply water to the spray pump 43, the problem of the spray pump 43 being unable to draw water due to air leakage during dry pumping is solved. In addition, in this embodiment, a water application pump 52 is added, which can play a humidification function and also handle the accumulated water in case of dirt blockage or freezing blockage.

[0102] It should be noted that the opening timing of the water application pump 52 is not limited to the above. For example, when the outdoor temperature is not lower than the set value, the water application pump 52 can also be turned on. The booster pump 42, the spray pump 43, and the water application pump 52 can jointly consume the outdoor condensate to improve the consumption efficiency of the condensate. Of course, if the load capacity of the circuit board is relatively low, only one of the indoor pumps (i.e., the booster pump 42 and the spray pump 43) and the outdoor pump (i.e., the water application pump 52) can be set to be turned on. For example, only the indoor pumps (i.e., the booster pump 42 and the spray pump 43) are turned on, or only the outdoor pump (i.e., the water application pump 52) is turned on. It should be noted that the sequence of turning on the booster pump 42 and the spray pump 43 is not limited to the above. They can be turned on and off simultaneously, or one can be turned on first and the other later. It can be set according to the actual situation and is not restricted here.

[0103] Next, a control method for a window air conditioner according to an embodiment of the present invention will be described, which is used to control the window air conditioner in any of the above embodiments.

[0104] Combined with Figure 3 , the control method may include steps: S1, obtaining the operating mode of the window air conditioner; S2, taking corresponding control measures for the water treatment system according to the operating mode of the window air conditioner.

[0105] Combined withFigure 4 The control method further includes the steps of: S11. When it is determined that the refrigeration mode is entered (i.e., when the operating mode of the window air conditioner is the refrigeration mode), S21. Adopt a first control scheme for the water treatment system. Combining Figure 5 The first control scheme includes the steps of: S211. Determine whether the first start condition is satisfied; S212. Under the first start condition, start the booster pump 42 and the spray pump 43. Thus, in the refrigeration mode, the condensed water recovered by the second water recovery container 22 of the indoor unit component 2 is consumed.

[0106] Combining Figure 6 The control method further includes the steps of: S12. When it is determined that the heating mode is entered (i.e., when the operating mode of the window air conditioner is the heating mode), S22. Adopt a second control scheme for the water treatment system. Combining Figure 7 The second control scheme includes the steps of: S2211. Determine whether the second start condition is satisfied; S2212. Under the second start condition, start the booster pump 42 and the spray pump 43. Combining Figure 8 The second control scheme further includes the steps of: S2221. Determine whether the third start condition is satisfied; S2222. Under the third start condition, start the drain pump 41. Thus, in the heating mode, the condensed water recovered by the first water recovery container 12 of the outdoor unit component 1 can be consumed.

[0107] It can be understood that when it is determined that the refrigeration mode is entered, if the first start condition is not satisfied, the booster pump 42 and the spray pump 43 are not started or are turned off. When it is determined that the heating mode is entered, if the second start condition is not satisfied, the booster pump 42 and the spray pump 43 are not started or are turned off. If the third start condition is not satisfied, the drain pump 41 is not started or is turned off.

[0108] Thus, according to the control method of the embodiment of the present invention, in the refrigeration mode, the condensed water recovered by the second water recovery container 22 of the indoor unit component 2 can be consumed, and in the heating mode, the condensed water recovered by the first water recovery container 12 of the outdoor unit component 1 can be consumed. Different water treatment schemes are adopted according to different operating modes of the window air conditioner, which can be more targeted, more energy-saving and more effective in solving the problem of water accumulation.

[0109] In some embodiments, the first startup condition is that the water level in the second water recovery container 22 reaches the indoor set water level value. That is, when it is determined that the refrigeration mode is entered (i.e., the operating mode of the window air conditioner is the refrigeration mode), it is judged whether the water level in the second water recovery container 22 reaches the indoor set water level value. If the water level in the second water recovery container 22 reaches the indoor set water level value, the booster pump 42 and the spray pump 43 are started, so that the condensed water recovered by the second water recovery container 22 can be atomized and discharged through the spray head 44. Thus, by starting the booster pump 42 and the spray pump 43 when the water level in the second water recovery container 22 reaches the indoor set water level value, electric energy can be saved and the service life of the booster pump 42 and the spray pump 43 can be extended.

[0110] When the second water recovery container 22 is provided with an indoor high and low water level switch, for example, when the indoor high and low water level switch is arranged in the indoor confluence box of the second water recovery container 22, the low water level switch of the indoor high and low water level switch will be triggered when the indoor set water level value is reached, and at this time, the booster pump 42 and the spray pump 43 can be started.

[0111] In some embodiments, the second startup condition is that the water level in the second water recovery container 22 reaches the indoor set water level value. That is, when it is determined that the heating mode is entered (i.e., the operating mode of the window air conditioner is the heating mode), it is judged whether the water level in the second water recovery container 22 reaches the indoor set water level value. If the water level in the second water recovery container 22 reaches the indoor set water level value, the booster pump 42 and the spray pump 43 are started. Thus, the water collected by the second water recovery container 22 (mostly the condensed water recovered by the first water recovery container 12 conveyed by the drain pump 41) can be atomized and discharged through the spray head 44. Thus, by starting the booster pump 42 and the spray pump 43 when the water level in the second water recovery container 22 reaches the indoor set water level value, electric energy can be saved and the service life of the booster pump 42 and the spray pump 43 can be extended.

[0112] When the second water recovery container 22 is provided with an indoor high and low water level switch, for example, when the indoor high and low water level switch is arranged in the indoor confluence box of the second water recovery container 22, the low water level switch of the indoor high and low water level switch will be triggered when the indoor set water level value is reached, and at this time, the booster pump 42 and the spray pump 43 can be started.

[0113] Alternatively, in some other embodiments, the second start condition is that the water level in the second water recovery container 22 reaches the indoor set water level value and the outdoor temperature is higher than the set ambient temperature. That is, when it is determined to enter the heating mode (i.e., the operating mode of the window air conditioner is the heating mode), in addition to determining whether the water level in the second water recovery container 22 reaches the indoor set water level value, it is also necessary to determine whether the outdoor temperature is greater than the set ambient temperature. If the water level in the second water recovery container 22 reaches the indoor set water level value and the outdoor temperature is greater than the set ambient temperature, the booster pump 42 and the spray pump 43 are started. Thus, the water collected in the second water recovery container 22 (mostly the condensed water recovered by the first water recovery container 12 conveyed by the drain pump 41) can be atomized and discharged through the spray head 44. Thereby, the problem that the spray head 44 cannot spray due to freezing at a lower outdoor temperature can be avoided. Of course, if an anti-freezing device is provided, the problem of freezing of the spray head 44 can be avoided, or in areas where the winter temperature is not low, it is not necessary to determine the outdoor temperature. The specific value of the set ambient temperature can be set according to actual requirements. For example, it can be any value between 3°C and 10°C.

[0114] In some embodiments, the third start condition is that the water level in the second water recovery container 22 does not reach the indoor set water level value and the water level in the first water recovery container 12 reaches the outdoor set water level value. That is, when it is determined to enter the heating mode (i.e., the operating mode of the window air conditioner is the heating mode), it is determined whether the water level in the second water recovery container 22 reaches the indoor set water level value and whether the water level in the first water recovery container 12 reaches the outdoor set water level value. If the water level in the second water recovery container 22 does not reach the indoor set water level value and the water level in the first water recovery container 12 reaches the outdoor set water level value, the drain pump 41 is started.

[0115] In short, in the heating mode, when the water level on the indoor side is insufficient and the water level on the outdoor side is sufficient, and both conditions are met, the drain pump 41 is started. In this way, when the flow rate of the drain pump 41 is greater than the flow rate of the booster pump 42, problems such as the water level in the second water recovery container 22 overflowing due to being too high can be avoided. Exemplarily, the flow rate of the booster pump 42 can be set to be less than the flow rate of the drain pump 41, so that the working noise of the booster pump 42 can be relatively small.

[0116] When the first water recovery container 12 is provided with an outdoor high and low water level switch, for example, when the outdoor high and low water level switch is arranged in the outdoor drainage box of the first water recovery container 12, the low water level switch of the outdoor high and low water level switch will be triggered when the outdoor set water level value is reached. At this time, if the water level in the second water recovery container 22 does not reach the indoor set water level value, the drain pump 41 can be started.

[0117] In some embodiments, refer to Figure 9, when the water treatment system includes the application pump 52, the second control scheme further includes the steps of: S2231, determining whether the fourth start condition is satisfied; S2232, starting the application pump 52 under the fourth start condition. The fourth start condition is that the water level in the second water recovery container 22 reaches the indoor set water level value and the outdoor temperature is lower than the set ambient temperature.

[0118] That is, when it is determined that the heating mode is entered (i.e., the operating mode of the window air conditioner is the heating mode), it is judged whether the water level in the second water recovery container 22 reaches the indoor set water level value, and it is judged whether the outdoor temperature is less than or equal to the set ambient temperature (for example, any value in the above 3°C - 10°C). If the water level in the second water recovery container 22 reaches the indoor set water level value and the outdoor temperature is less than or equal to the set ambient temperature, the application pump 52 is started. Thus, under the condition that the outdoor temperature is relatively low, the accumulated water can be applied to the indoor heat exchanger 21 to consume the condensed water, avoid the problem that the spray head 44 cannot spray due to freezing, and enable the condensed water to be consumed smoothly.

[0119] It can be understood that when the fourth start condition is satisfied (i.e., the water level in the second water recovery container 22 reaches the indoor set water level value and the outdoor temperature is lower than the set ambient temperature), the second start condition (i.e., the water level in the second water recovery container 22 reaches the indoor set water level value and the outdoor temperature is higher than the set ambient temperature) is no longer satisfied. Therefore, when the fourth start condition is satisfied, the booster pump 42 and the spray pump 43 are not started or are turned off.

[0120] Next, with reference to Figure 10 , the control method of the window air conditioner according to a specific embodiment of the present invention is described.

[0121] When it is determined that the cooling mode is entered, it is judged whether the water level in the second water recovery container 22 reaches the indoor set water level value. If it reaches, the booster pump 42 and the spray pump 43 are started. If it does not reach, the booster pump 42 and the spray pump 43 are not started or are turned off.

[0122] When it is determined that the heating mode is entered, it is judged whether the water level in the second water recovery container 22 reaches the indoor set water level value. If the water level in the second water recovery container 22 does not reach the indoor set water level value, it is then continuously judged whether the water level in the first water recovery container 12 reaches the outdoor set water level value. If it reaches, the drain pump 41 is started; if it does not reach, the drain pump 41 is not started or is turned off. If the water level in the second water recovery container 22 reaches the indoor set water level value, it is then continuously judged whether the drain pump 41 is started. If the drain pump 41 is running, the drain pump 41 is turned off. If the drain pump 41 is not started or has been turned off, it is then further judged whether the outdoor temperature is higher than the set ambient temperature. If so, the booster pump 42 and the spray pump 43 are started; if not, the booster pump 42 and the spray pump 43 are not started or are turned off.

[0123] Next, with reference to Figure 11 , a control method for a window air conditioner according to a specific embodiment of the present invention will be described.

[0124] When it is determined that the cooling mode is entered, it is judged whether the water level in the second water recovery container 22 reaches the indoor set water level value. If it reaches, the booster pump 42 and the spray pump 43 are started; if it does not reach, the booster pump 42 and the spray pump 43 are not started or are turned off.

[0125] When it is determined that the heating mode is entered, it is judged whether the water level in the second water recovery container 22 reaches the indoor set water level value. If the water level in the second water recovery container 22 does not reach the indoor set water level value, it is then continuously judged whether the water level in the first water recovery container 12 reaches the outdoor set water level value. If it reaches, the drain pump 41 is started; if it does not reach, the drain pump 41 is not started or is turned off. If the water level in the second water recovery container 22 reaches the indoor set water level value, it is then continuously judged whether the drain pump 41 is started. If the drain pump 41 is running, the drain pump 41 is turned off. If the drain pump 41 is not started or has been turned off, it is then further judged whether the outdoor temperature is higher than the set ambient temperature. If so, the booster pump 42 and the spray pump 43 are started; if not, the booster pump 42 and the spray pump 43 are not started or are turned off, and the water application pump 52 is started.
