[0029] Combination Figure 1 , 2 As shown, the embodiment of the present disclosure provides a water washing module for a wall-mounted air conditioner, comprising: a housing 10, a cross-flow fan 20 and a water supply assembly. The housing 10 is provided with an air inlet 11 at the lower back side, and an air outlet 12 at the upper front side. A fan accommodating space is provided at the air outlet 12, and a purification space is provided between the fan accommodating space and the air inlet 11; the cross-flow fan 20 is provided in the fan accommodating space, and can rotate to generate wind force that drives the air flow to flow through the air inlet 11, the purification space and the air outlet 12 in sequence; the water supply assembly includes a spraying member 210 that is provided in the purification space and can spray water in the purification space to form a water curtain.

[0030] Driven by the cross-flow fan 20, the airflow enters the water washing module from the air inlet 11 at the lower back side of the housing 10, passes through the purification space and is sprayed and purified by the spraying member 210, then passes through the fan accommodating space, and finally flows out from the air outlet 12 at the upper front side of the housing 10. The air inlet 11 and the air outlet 12 are located on different sides of the water washing module, which can reduce the mutual interference between the airflow inlet and the airflow out of the water washing module, thereby improving the purification effect of the water washing module on the airflow.

[0031] The front side of the housing 10 refers to the side of the water washing module facing the user, and the back side refers to the side opposite to the front side. The back side includes the back, left and right sides of the water washing module. When the wall-mounted air conditioner is set near the window, the back side of the water washing module can face the window to facilitate air intake. When the back side of the wall-mounted air conditioner is set against the wall, the water washing module can still take in air through the air inlets 11 on the left and right sides. The water washing module takes in air from the lower back side of the housing 10 and exhausts air from the upper front side. The air inlet and outlet positions are located on different sides and at different heights of the housing 10, which can minimize mutual interference between airflows and reduce the possibility of purified air blown out from the air outlet 12 being re-inhaled into the air inlet 11.

[0032] A fan accommodating space is provided at the air outlet 12, and a crossflow fan 20 is provided in the fan accommodating space. Through the rotation of the crossflow fan 20, a wind force is formed that can drive the airflow to flow through the air inlet 11, the purification space and the air outlet 12 in sequence. The crossflow fan 20 can make the wind speed of the airflow pass through the above structure evenly, so that the airflow can flow upward into the fan accommodating space after being washed by water in the purification space, and then flow out from the air outlet 12. The crossflow fan 20 is provided at the air outlet 12, so that the airflow can pass through the crossflow fan 20 after being purified, and prevent dust and other particles in the air from adhering to the crossflow fan 20, which is difficult to clean.

[0033] The water supply component sprays water through the spray part to form a water curtain or water curtain in the purification space, and dust and other particles therein are washed away when the airflow passes through the water curtain or water curtain. Optionally, the spray part includes a first water pipe and a second water pipe arranged side by side, the first water pipe is provided with a first nozzle, the second water pipe is provided with a second nozzle, and the first nozzle and the second nozzle are coaxially arranged opposite to each other. In this way, when the first nozzle and the second nozzle spray water together, the water flow sprayed in opposite directions can form a water curtain after collision. Optionally, the first nozzle and the second nozzle are arranged in upper and lower positions. In this way, the water curtain takes the axis of the first nozzle and the second nozzle as the center of the circle, and extends radially to the outer periphery and obliquely downward, so that the airflow can pass through the water curtain when it flows from bottom to top. Optionally, the first water pipe and the second water pipe are arranged side by side in upper and lower positions, the first water pipe is closer to the air outlet side of the purification space than the second water pipe, and a baffle is provided at the position of the first water pipe facing away from the first nozzle. When the first nozzle and the second nozzle spray against each other, water droplets are easily splashed out near the nozzles. A baffle is provided on the first water pipe to prevent the water droplets from splashing toward the air outlet side of the purification space, thereby avoiding being carried out of the purification space by the rising airflow.

[0034] Optionally, a water receiving tray is provided at the bottom of the housing 10, and the water receiving tray is provided with a drain pipe. Water droplets formed by spraying drip downward into the water receiving tray and are discharged through the drain pipe of the water receiving tray. Optionally, the water washing module further includes a water storage tank, which supplies water to the spraying part. In order to achieve continuous spraying of the spraying part, an additional water storage tank can be provided to supply water to the spraying part.

[0035] Optionally, an electric heater is provided at the air outlet 12. The airflow of the air outlet 12 is heated by the electric heater to avoid discomfort to the human body caused by the airflow being too cold. Optionally, the heating power of the electric heater is adjusted by real-time monitoring of the air outlet temperature. In this way, the airflow blown out of the air outlet 12 can maintain a suitable temperature.

[0036] Combination Figure 2 As shown, optionally, a waist ring 16 is sleeved on the upper side of the housing 10, and a second vent is arranged at the position of the waist ring 16 corresponding to the air outlet 12. The sleeve waist ring 16 can make the structure of the housing 10 more solid, and when the washing module is connected to other devices, the waist ring 16 can cover the connection and improve the integrity of the appearance.

[0037] In some embodiments, a water retaining assembly is provided on the air outlet side of the purification space. Since the airflow flows upward in the purification space, it is easy to carry some moisture upward after passing through the water curtain, which may cause the moisture to enter the fan accommodating space or even be taken out of the air outlet 12. Therefore, a water retaining assembly is provided on the air outlet side of the purification space to block the moisture in the airflow and prevent the moisture from being taken out of the purification space. Optionally, the water retaining assembly covers the air outlet side of the purification space. In this way, it is possible to more comprehensively prevent moisture from being taken out of the purification space.

[0038] In some embodiments, the water retaining assembly includes a baffle and a filter. The baffle is disposed on the air outlet side of the purification space and is provided with an opening; the filter is disposed at the opening to allow airflow to pass through and block moisture in the airflow. When the airflow flows through the water retaining assembly, the baffle can prevent the airflow from passing through, and the airflow flows toward the opening and continues to flow upward through the filter. When the moisture in the airflow passes through the filter, it is separated from the airflow and attached to the filter. When a large amount of moisture accumulates on the filter, large water droplets are formed and drip downward.

[0039] Combination Figure 2 As shown, in some embodiments, the fan accommodating space includes a volute 30, and the volute 30 includes a main channel 301 in a cylindrical shape, and an air inlet is provided at the lower side of the main channel 301, and the air inlet is communicated with the air outlet side of the purification space; wherein, the crossflow fan 20 is arranged in the main channel 301. The cylindrical main channel 301 can accommodate the crossflow fan 20, and with the cooperation of the crossflow fan 20, a large amount of air flow can enter the volute 30. The main channel 301 takes in air through the air inlet at the lower side, and the air inlet is communicated with the air outlet side of the purification space, so that the air in the purification space after water washing and purification can flow upward into the main channel 301.

[0040] Optionally, the volute 30 further includes an arc-shaped air outlet duct 302, which is connected to the main channel 301, and the air outlet is arranged corresponding to the air outlet 12. The air outlet duct 302 is arc-shaped, so that the airflow flowing out of the crossflow fan 20 in the main channel 301 flows smoothly to the air outlet duct 302 and flows out from the air outlet duct 302. The air outlet of the air outlet duct 302 is arranged corresponding to the air outlet 12, and the airflow flows directly from the air outlet 12 to the outside of the water washing module after leaving the fan accommodating space.

[0041] Combination Figure 2 , 3As shown, in some embodiments, the water washing module further includes a water tank structure 100, which is arranged in the purification space and has an air flow inlet 410 and an air flow outlet 420; wherein the water supply component is arranged in the water tank structure 100. After the air flow enters the water washing module from the air inlet 11, it enters the water tank structure through the air flow inlet 410, is washed and purified by the water supply component in the water tank structure 100, flows out of the water tank structure from the air flow outlet 420, and then enters the fan accommodating space. The water supply component is arranged in the water tank structure 100, so that the water washing process is completed in the water tank structure 100, and the dripping water after water washing can be fully collected, and water droplets can be prevented from splashing on other components of the water washing module as much as possible.

[0042] Combination Figure 2 , 3 As shown, in some embodiments, the air inlet 410 is arranged on the side wall of the water tank structure 100, and the air outlet 420 is arranged on the top of the water tank structure 100. The air inlet 410 is arranged on the side wall of the water tank structure 100, so that it is convenient to correspond to the position of the air inlet 11 of the water washing module, and it is convenient to take in air. The air outlet 420 is arranged on the top of the water tank structure 100, so that the purified air flow flows upward into the fan accommodating space under the drive of the cross-flow fan 20 above.

[0043] Optionally, the water tank structure includes a box body 101 and a cover assembly 400, the upper side of the box body 101 is open to store water, and the cover assembly 400 covers the top of the box body 101. Among them, the air inlet 410 and the air outlet 420 are arranged on the cover assembly 400, and the spray part 210 is arranged between the air inlet 410 and the air outlet 420. The cover assembly 400 covers the top of the box body 101, so that the water tank structure is more airtight, and the water in the box body 101 can be prevented from splashing out of the box body 101. In addition, when the user takes and places the box body 101, even if it shakes, the water in the box body 101 can be prevented from spilling out, thereby improving the convenience of taking and placing. The cover assembly 400 is provided with an air inlet 410 and an air outlet 420, so that air can enter and exit the water tank structure through the cover assembly 400. The spray element 210 is disposed between the air flow inlet 410 and the air flow outlet 420. When the air flows through the inside of the water tank structure, the spray element 210 sprays water to the air flow to remove dust and other particles in the water to achieve purification.

[0044] Through this embodiment, not only can the airtightness of the water tank structure 100 be improved to prevent water splashing, but also the cover assembly 400 and the spray part 210 can be taken out at the same time as the box body 101 is taken out. In this way, it is also convenient to repair the cover assembly 400 or the spray part 210. In addition, through this embodiment, the water tank structure 100 is designed as a module integrating spraying and water storage, which is convenient for setting the water tank structure 100 on a device that needs to be equipped with a water washing function, thereby expanding the application range of the water tank structure 100.

[0045] Combination Figure 4 As shown, in some embodiments, the cover assembly 400 includes a first cover body 430 and a second cover body 440, the first cover body 430 covers the upper side of the box body 101, and is provided with a guide structure 431 for guiding water flow into the interior of the box body 101. The second cover body 440 is arranged above the first cover body 430. The first cover body 430 and the second cover body 440 enclose a purification space, and the airflow inlet 410 and the airflow outlet 420 are arranged on the second cover body 440.

[0046] The first cover 430 covers the upper side of the box 101, improves the airtightness of the box 101, and makes it difficult for the water inside to flow out even if the box 101 shakes. During the water washing process, water drops will first fall on the surface of the first cover 430. The first cover 430 is provided with a guide structure 431, which can make the water falling on the first cover 430 flow into the box 101 along the guide structure 431. By setting the first cover 430, it is also possible to avoid splashing caused by water drops falling directly into the water surface of the box 101, thereby preventing the water flow from bringing the splashing water out of the water tank structure. The second cover 440 is arranged above the first cover 430, and encloses a purification space with the first cover 430. The spray part 210 is located in the purification space. The airflow enters the purification space from the airflow inlet 410 of the second cover 440, completes the water washing process under the spray of the spray part 210, and flows out from the airflow outlet 420 of the second cover 440.

[0047] Through this embodiment, the air is washed in the cover assembly 400 and can flow from the first cover body 430 to the box body 101 for storage. While integrating the water storage function and the purification function, the water storage space is separated from the purification space, the spaces do not interfere with each other, and the noise generated during the washing process is reduced.

[0048] Optionally, the upper surface of the first cover 430 is concave downward and arc-shaped, and the guide structure 431 is arranged at the lowest position of the upper surface. The upper surface of the first cover 430 is concave downward, and when water falls on the first cover 430, it can automatically flow to the lowest position of the upper surface, and then gather to the guide structure 431, and flow into the box 101. Optionally, the guide structure 431 is a guide channel. Water flows into the box 101 through the guide channel.

[0049] Optionally, a buckle 432 is provided at the edge of the first cover 430, and a matching block 433 is provided at the edge of the box 101 corresponding to the buckle 432. The first cover 430 is connected and separated from the box 101 by matching the buckle 432 with the block 433.

[0050] Combination Figure 7As shown, optionally, a water receiving structure 434 is provided on the upper surface of the first cover body 430, and the water receiving structure 434 is strip-shaped and the upper surface is an arc-shaped surface, and the water receiving structure 434 is arranged corresponding to the extension path of the water pipe 211. The water flowing out of the water outlet 212 falls on the arc-shaped surface of the water receiving structure 434, which can eliminate the noise generated when the water droplets hit the plane. Optionally, a guide plate 435 is provided on the lower surface of the water receiving structure 434, and the guide plate 435 is connected to the upper surface of the first cover body 430. The water droplets falling on the water receiving structure 434 flow along the guide plate 435 to the upper surface of the first cover body 430. Optionally, the number of guide plates 435 is multiple and arranged at intervals. In this way, the water flow that directly falls on the upper surface of the first cover body 430 can flow to the low position of the first cover body 430 through the gap between the guide plates 435.

[0051] Combination Figures 3 to 5 As shown, in some embodiments, the second cover body 440 includes a top plate and a side plate, the top plate is arranged above the first cover body 430; the side plate is arranged around the periphery of the top plate and is located between the top plate and the first cover body 430; wherein the air flow inlet 410 is arranged on the side plate, and the air flow outlet 420 is arranged on the top plate.

[0052] The top plate and side plates of the first cover body 430 and the second cover body 440 enclose a purification space, and air flows in from the airflow inlet 410 of the side plate and flows out from the airflow outlet 420 of the top plate. This arrangement can keep the inlet airflow and the outlet airflow as far away as possible to prevent interference with each other. In addition, the airflow inlet 410 is arranged on the side plate, and when the water tank structure is arranged on the water washing module, it is convenient to arrange the air inlet 11 on the side wall of the water washing module corresponding to the airflow inlet 410. The airflow outlet 420 is arranged on the top plate, and a fan can be arranged above the top plate to provide power for the airflow.

[0053] Combination Figures 3 to 5 As shown, in some embodiments, the top plate includes a first area and a second area, the first area is close to the air flow inlet 410, and is provided with a return air port 441 for air intake; the second area is farther away from the air flow inlet 410 than the first area; wherein the air flow outlet 420 is arranged in the second area. In the area of ​​the top plate close to the air flow inlet 410, that is, the first area, a return air port 441 for air intake is arranged, which can increase the air intake volume of the purification space. The return air port 441 is close to the air flow inlet 410, which facilitates the introduction of air flow into the return air port 441. The air flow outlet 420 is located in the second area far away from the air flow inlet 410, which can avoid interference with the intake air flow. The division of the first area and the second area can be to divide the top plate into two areas equally, the area close to the air flow inlet 410 as the first area, and the area far away from the air flow inlet 410 as the second area.

The user can view the internal situation of the water tank structure 100 through the transparent panel, which can be used to check whether the spraying is smooth during water washing so as to make timely maintenance, or to watch the water washing scene to improve psychological comfort. Since the water tank structure 100 is located inside the housing 10, when the water tank structure 100 needs to be viewed, the housing 10 can be opened to expose the water tank structure 100, or a window 13 can be provided in the housing 10 to view the water tank structure 100 through the window 13.

[0061] Combination Figure 4As shown, in some embodiments, the upper surface of the first cover 430 is provided with a point-contact power terminal 436, which is electrically connected to the water pump 230 through an electric wire and extends to the rear side of the first cover 430. The point-contact power terminal 436 prevents the water tank structure from having exposed wires, and is convenient for powering on, with a compact overall structure. Extending from the rear side of the first cover 430 facilitates the point-contact power terminal 436 to be connected to the power supply module.

[0062] Combination Figure 4 , 5 As shown, in some embodiments, the second cover body 440 includes a top plate and a side plate, the top plate is arranged above the first cover body 430; the side plate is arranged around the outer periphery of the top plate and is located between the top plate and the first cover body 430; the airflow inlet 410 is arranged on the side plate, and the opening 442 for exposing the point-contact power connection terminal 436 is arranged on the side plate and is close to the airflow inlet 410. There is an airflow flowing into the purification space at the airflow inlet 410. Under the impact of the airflow, the water flow formed by the spraying member 210 is difficult to splash to the airflow inlet 410. The opening 442 for exposing the point-contact power connection terminal 436 is arranged on the side plate of the first cover body 430 and is close to the airflow inlet 410. When the power connection terminal extends from the opening 442, water droplets can be prevented from splashing to the power connection terminal, thereby reducing safety hazards.

[0063] Combination Figure 1 , 2 As shown, in some embodiments, the front side of the housing 10 is a front panel 14, and a window 13 is provided at the position of the front panel 14 corresponding to the purification space. By providing the window 13, on the one hand, the user can watch the water washing process through the window 13, thereby improving the visual effect of the water washing module; on the other hand, if the spray part of the water washing module is blocked and there is a problem with the water spray, the user can find it in time and take maintenance measures as soon as possible. In the case where a water tank structure is provided in the purification space, a transparent panel is provided on the front side of the water tank structure, and the user can see the internal situation of the water tank structure through the window 13 and the transparent panel. Optionally, the rear side of the housing 10 is a rear panel 15, and the air inlet 11 is provided on the rear panel 15. Allow the airflow to enter from the rear side of the water washing module.
