[0043] After the air conditioner has been used for a long time, the filter at the air inlet needs to be cleaned to ensure the cleanliness of the air. The existing air conditioner has a self-cleaning function. After the self-cleaning function is activated, condensed water flows into the water tank on the chassis, and the water in the water tank is pumped out by a water pump to clean the filter. After cleaning, the water is discharged through the drain valve.

[0044] The water pump and the drain valve of the filter cleaning module occupy a large space in the air conditioner's storage chamber, which is not convenient for miniaturization of the air conditioner and has a high cost.

[0045] In view of this, the utility model provides a wall-mounted air-conditioning indoor unit.

[0046] In the embodiment of the present utility model, Figure 2 and Figure 3 As shown, the wall-mounted air-conditioning indoor unit includes a shell 100, a water receiving tray 500, a filter assembly 200, a cleaning assembly 400 and a transmission assembly 300. The shell 100 is provided with an air inlet, and the shell 100 has a accommodating chamber 110, in which a heat exchanger is arranged; the water receiving tray 500 is arranged corresponding to the heat exchanger, and one side of the water receiving tray 500 forms a water storage tank 111 connected to the water receiving tray 500, and the height of the water receiving tray 500 is greater than the height of the water storage tank 111; the filter assembly 200 is arranged corresponding to the air inlet; the cleaning assembly 400 is at least partially located in the water storage tank 111; the transmission assembly 300 is installed on the shell 100, and the transmission assembly 300 is used to drive the filter assembly 200 to move and make the filter assembly 200 cleaned by the cleaning assembly 400.

[0047] Specifically, an air inlet is provided at the upper part of the housing 100 of the wall-mounted air conditioner indoor unit, and the upper part refers to the upper part of the housing 100. In this embodiment, the air inlet is arranged at the top of the air conditioner. The accommodating cavity 110 formed in the housing 100 is used to accommodate and install other components of the wall-mounted air conditioner indoor unit, wherein the filter assembly 200 is installed at the air inlet, and is used to filter the air blown out from the air inlet, filter the dust and sundries therein, etc., so that the air outlet of the air conditioner indoor unit is clean and free of foreign matter.

[0048] After long-term use, dust, impurities, etc. may clog some meshes of the filter assembly 200, resulting in poor air outlet effect of the indoor unit of the wall-mounted air conditioner. In addition, the air outlet of the air conditioner is affected by dust and impurities, resulting in insufficient cleanliness of the air outlet. Therefore, it is necessary to clean the filter assembly 200. In the existing scheme, the filter assembly 200 with the air inlet generally cleaned at the upper part of the housing 100 is introduced into the vicinity of the upper cleaning assembly 400 by a water pump, and the cleaning assembly 400 is driven to move by the transmission assembly 300 so that the filter assembly 200 is cleaned by the cleaning assembly 400. In the present embodiment, the cleaning position of the filter assembly 200 is set in the water tank 111 on one side of the water receiving tray 500. The height of the water tank 111 is less than the height of the water receiving tray 500. That is, the condensed water dripping from the heat exchanger arranged above the water receiving tray 500 gathers on the water receiving tray 500 and finally flows into the water tank 111. Therefore, the step of introducing water into the upper part of the shell 100 with a water pump is omitted, which saves the available space of the accommodating chamber 110 and is conducive to the miniaturized design of the indoor unit of the wall-mounted air conditioner.

[0049] The water receiving tray 500 is generally configured as a front water receiving tray and a rear water receiving tray, the front water receiving tray is located at the front side of the accommodating chamber 110, and the rear water receiving tray is located at the rear side of the accommodating chamber 110. The wall-mounted air conditioner indoor unit also includes a volute and a chassis. Generally, the front water receiving tray is connected to the volute, and the rear water receiving tray is connected to the chassis. In this embodiment, the water receiving tray 500 can be a front water receiving tray, a rear water receiving tray, or both a front water receiving tray and a rear water receiving tray.

[0050] It should be further explained that the filter assembly 200 at least includes a filter. In addition, the filter assembly 200 also includes a transmission rack 210 for installing the filter, wherein the filter is installed between the transmission racks 210. The filter is a conventional structure in the technical field and has not been improved in this embodiment, so it is not shown in the figure. A transmission assembly 300 that cooperates with the transmission rack 210 is provided in the wall-mounted air conditioner indoor unit. Specifically, the transmission is carried out by meshing the transmission rack 210 with the gear 310 of the transmission assembly 300. Considering that the transmission rack 210 needs to bend during the transmission process, the material of the transmission rack 210 is set to have a flexible material, which can be a flexible plastic or the like.

[0051] In addition, considering that the filter assembly 200 is meshed with the gear 310 for transmission, the cleaning assembly 400 is arranged close to the gear 310 so that a cleaning gap is formed between the cleaning assembly 400 and the gear 310, so that the cleaning assembly 400 can clean the filter assembly 200, wherein the cleaning assembly 400 must at least include a brush structure for cleaning dust and debris in the filter mesh.

[0052] Considering that it takes a certain amount of time to clean the filter assembly 200, the water in the water tank 111 needs to be slowly drained to ensure that there is enough water to clean the filter assembly 200 and that the dirty water after cleaning the filter can be discharged in time. Therefore, a throttle port 121 is provided on the wall of the water tank 111. The throttle port 121 limits the flow rate of the water in the water tank 111 so that the water in the water tank 111 is sufficient to fully clean the filter assembly 200. By providing a throttle port 121 on the wall of the water tank 111 to throttle the water discharged from the water tank 111, and then replacing the drain valve, the available space in the accommodating chamber 110 is further saved, which is conducive to the miniaturization of the wall-mounted air conditioner indoor unit, and optimizes the overall structure and reduces the cost.

[0053] The technical solution of the utility model adopts the method of partially disposing the cleaning component 400 for cleaning the filter assembly 200 in the water storage tank 111, and opening a throttle port 121 on the tank wall of the water storage tank 111, thereby replacing the water pump and the drain valve in the cleaning module in the original air conditioner, saving the installation space of the accommodating chamber 110 in the shell 100, facilitating the miniaturization of the wall-mounted air conditioner indoor unit, and also reducing the cost for the cleaning module.

[0054] In one embodiment, see Figure 7 The water receiving tray 500 includes a front water receiving tray and a rear water receiving tray. The front water receiving tray is connected to the water storage tank 111. The condensed water accumulated in the rear water receiving tray is introduced into the front water receiving tray and flows into the water storage tank 111 via the front water receiving tray.

[0055] It should be noted that the water receiving pan 500 includes a front water receiving pan and a rear water receiving pan, which correspond to the front and rear sides of the plurality of heat exchangers, respectively. The front water receiving pan is connected to the water storage tank 111, so that the water in the front water receiving pan can flow into the water storage tank 111, and the condensed water gathered in the rear water receiving pan is first introduced into the front water receiving pan and then flows into the water storage tank 111 via the front water receiving pan. The introduction method can be to introduce the condensed water in the rear water receiving pan into the front water receiving pan through a guide pipe. In this embodiment, the condensed water in the front water receiving pan and the rear water receiving pan can flow into the water storage tank 111 only by connecting the front water receiving pan and the water storage tank 111.

[0056] Optionally, see Figure 7 The water receiving tray 500 includes a front water receiving tray and a rear water receiving tray. The rear water receiving tray is connected to the water storage tank 111. The condensed water accumulated in the front water receiving tray is introduced into the rear water receiving tray and flows into the water storage tank 111 through the rear water receiving tray.

[0057] Specifically, in this embodiment, the water receiving pan 500 includes a front water receiving pan and a rear water receiving pan, which correspond to the front and rear sides of the plurality of heat exchangers, respectively. The rear water receiving pan is connected to the water storage tank 111, so that the water in the rear water receiving pan can flow into the water storage tank 111. The condensed water collected in the front water receiving pan is first introduced into the rear water receiving pan and then flows into the water storage tank 111 via the rear water receiving pan. The introduction method can be to introduce the condensed water in the front water receiving pan into the rear water receiving pan through a guide pipe. In this embodiment, the condensed water in the front water receiving pan and the rear water receiving pan can flow into the water storage tank 111 only by connecting the rear water receiving pan and the water storage tank 111.

[0058] Optionally, the water receiving tray 500 includes a front water receiving tray and a rear water receiving tray, and the front water receiving tray and the rear water receiving tray are respectively connected to the water storage tank 111 .

[0059] In this embodiment, the water receiving tray 500 includes a front water receiving tray and a rear water receiving tray, which respectively correspond to the front and rear sides of multiple heat exchangers. The front water receiving tray and the rear water receiving tray are respectively connected to the water storage tank 111, so that the condensed water in the front water receiving tray and the rear water receiving tray directly flows into the water storage tank 111.

[0060] In one embodiment, see Figure 4 and Figure 5 The water storage tank 111 has a first tank wall 120 and a second tank wall that are arranged opposite to each other. The throttling port 121 is opened on the first tank wall 120, and a water inlet 130 is opened on the second tank wall.

[0061] It should be noted that the throttle port 121 is provided in the first slot wall 120, and the water inlet 130 is provided in the second slot wall. The water entering from the water inlet 130 is discharged from the throttle port 121. Therefore, the first slot wall 120 and the second slot wall are arranged relative to each other so that the water flowing in from the water inlet 130 can be discharged from the throttle port 121. The throttle port 121 can slow down the outflow speed of the condensed water in the water storage tank 111, and prevent the condensed water from flowing out too fast and causing poor cleaning effect (when the water level in the water storage tank 111 is too low, the cleaning component 400 cannot be contaminated by the water in the water storage tank 111, thereby causing poor cleaning effect).

[0062] In one embodiment, see Figure 4 and Figure 5 The shell 100 is provided with a water outlet 140 , and the condensed water throttled by the throttle port 121 is discharged through the water outlet 140 .

[0063] It should be noted that the water outlet 140 is disposed close to the throttle port 121 , and the water discharged through the throttle port 121 is then discharged to the outside through the water outlet 140 .

[0064] In a preferred embodiment, see Figure 4 and Figure 5, the flow area of ​​the throttling port 121 is smaller than the flow area of ​​the water inlet 130 .

[0065] It should be noted that, considering that the throttling port 121 should have a better throttling effect, the flow area of ​​the throttling port 121 is set to be smaller than the flow area of ​​the water inlet 130, so that the water in the water tank 111 maintains a certain liquid level height to prevent the liquid level in the water tank 111 from being too low, resulting in the cleaning component 400 being unable to dip into the water in the water tank 111, which in turn leads to poor cleaning effect. Therefore, the flow area of ​​the throttling port 121 is set to be smaller than the flow area of ​​the water inlet 130.

[0066] In one embodiment, see Figure 4 and Figure 5 When the wall-mounted air conditioner indoor unit is in the cleaning mode, the water inlet rate of the water inlet 130 is greater than the water outlet rate of the throttle port 121.

[0067] Specifically, when the filter assembly 200 needs to be cleaned, there is a special cleaning mode for the user to choose. When the wall-mounted air-conditioning indoor unit is in the cleaning mode, the condensation rate of the condensed water is accelerated, and the water inlet rate of the water inlet 130 is greater than the water outlet rate of the throttle port 121. In this way, the water in the water tank 111 can maintain a certain liquid level height to prevent the liquid level in the water tank 111 from being too low, resulting in the cleaning assembly 400 being unable to dip into the water in the water tank 111.

[0068] In one embodiment, see Figure 5 and Figure 6 The number of the throttle openings 121 is set to be multiple, and the multiple throttle openings 121 are arranged at intervals on the first groove wall 120.

[0069] Specifically, considering that the throttling port 121 should have a certain water outlet rate, the number of the throttling ports 121 is set to be multiple, and the multiple throttling ports 121 are arranged at intervals on the first groove wall 120, wherein the number of the throttling ports 121 can be set to one, or two, or more. In the present embodiment, the number of the throttling ports 121 is three, wherein the number of the throttling ports 121 should not be set too many, otherwise a better throttling effect cannot be achieved.

[0070] In one embodiment, see Figure 5 and Figure 6 The bottom of the throttle port 121 is flush with the bottom of the water storage tank 111 .

[0071] It should be noted that the bottom of the throttle 121 is flush with the bottom of the water tank 111. Therefore, when the air conditioner is not used for a long time, the water accumulated in the water tank 111 will be completely drained through the throttle 121 to prevent the accumulation of stale water in the water tank 111 from causing the air outlet of the air conditioner to have an odor.

[0072] In one embodiment, see Figure 6 The width of the throttle opening 121 is L, and L satisfies 1mm≤L≤3mm.

[0073] It should be noted that the width of the throttle port 121 should not be set too narrow, otherwise after the throttle port 121 is blocked by foreign matter, the dirty water in the water tank 111 for cleaning the filter assembly 200 cannot be discharged smoothly from the water tank 111, so the width of the throttle port 121 is set to be greater than or equal to 1 mm; secondly, in order to ensure that the throttle port 121 has a throttling effect, the width of the throttle port 121 should not be set too wide. In this embodiment, the width of the throttle port 121 is set to be less than or equal to 3 mm.

[0074] In one embodiment, see Figure 6 , the width of the lower side of the throttle opening 121 is smaller than the width of the upper side of the throttle opening 121.

[0075] Specifically, the width of the lower side of the throttle port 121 is smaller than the width of the upper side of the throttle port 121. When the liquid level in the water tank 111 is low, the width of the throttle port 121 is narrower, and the water outlet rate of the throttle port 121 is slower, so that the liquid level in the water tank 111 can gradually rise. When the liquid level in the water tank 111 is high, the width of the throttle port 121 is wider, and the water outlet rate of the throttle port 121 is faster, so that the rising rate of the liquid level in the water tank 111 can be slowed down, or the liquid level in the water tank 111 can no longer rise. According to the above embodiment, the width of the throttle port 121 is set to be between 1 mm and 3 mm, so the width of the lower side of the throttle port 121 is smaller, closer to 1 mm, and the width of the upper side of the throttle port 121 is larger, closer to 3 mm.

[0076] In one embodiment, see Figure 5 and Figure 6 The throttle opening 121 passes through the upper end surface of the first groove wall 120 , and the throttle opening 121 is arranged on the first groove wall 120 in an inclined surface.

[0077] It should be noted that the throttle port 121 passes through the upper end surface of the first groove wall 120, and the throttle port 121 is arranged in an inclined surface. Considering that the wall thickness of the first groove wall 120 is relatively thin, compared with the throttle port 121 being arranged in a rectangular cross-section on the first groove wall 120, the first groove wall 120 has better structural strength, which can prevent the first groove wall 120 around the throttle port 121 from being squeezed and deformed by the water in the water storage tank 111, thereby ensuring the structural strength of the first groove wall 120.

[0078] In one embodiment, see Figure 3The transmission assembly 300 also includes a filter guide rail 320 , the gear 310 is located at the bottom of the filter guide rail 320 , a guide rail groove 321 is formed in the filter guide rail 320 , and the filter assembly 200 is driven in the guide rail groove 321 .

[0079] It should be noted that the transmission assembly 300 includes a filter guide rail 320, which is used to form a transmission path, which is formed by a guide rail groove 321. The filter assembly 200 is transmitted in the guide rail groove 321, wherein the bottom of the filter guide rail 320 has an opening, and the gear 310 is located at the opening. The position of the filter assembly 200 to be cleaned is firstly transmitted from the upper part of the guide rail assembly to the gear 310 at the bottom of the guide rail assembly, and then transmitted back to the upper part of the guide rail assembly after being cleaned by the cleaning assembly 400. The transmission of the filter assembly 200 is realized by motor drive.

[0080] By providing the filter guide rail 320 , the transmission path of the filter assembly 200 is limited, so that the transmission of the filter assembly 200 is not interfered by the outside world.

[0081] In one embodiment, see Figure 4 , the highest point of the throttle opening 121 in the horizontal direction is lower than the lowest point of the water inlet 130 in the horizontal direction.

[0082] Specifically, in order to ensure a better flow effect of the condensed water in the water storage tank 111, the condensed water should flow out smoothly from the throttle port 121, so the lowest point of the throttle port 121 in the horizontal direction should be at least lower than the lowest point of the water inlet 130 in the horizontal direction, so as to prevent the condensed water in the water storage tank 111 from backflowing into the water inlet 130. In this embodiment, further, the highest point of the throttle port 121 in the horizontal direction is also lower than the lowest point of the water inlet 130 in the horizontal direction, so as to completely prevent the condensed water in the water storage tank 111 from backflowing into the water inlet 130, and keep the waste water in the water storage tank 111 discharged only from the throttle hole.

[0083] In one embodiment, see Figure 7 The cleaning assembly 400 includes a roller brush 410 and a scraping tooth 420 . The roller brush 410 is connected to the housing 100 . The scraping tooth 420 is disposed at the bottom of the water storage tank 111 . The roller brush 410 is located between the gear 310 and the scraping tooth 420 .

[0084] It should be noted that the roller brush 410 is used to clean the dust and debris in the filter screen. The roller brush 410 is rotatably connected to the housing 100.
