[0044] Figure 1 is a schematic structural diagram of an air conditioner indoor unit according to an embodiment of the present utility model, as Figure 1 shown, and with reference to Figures 2 to 6 , an embodiment of the present utility model provides an air conditioner indoor unit. The air conditioner indoor unit includes a housing, an indoor heat exchanger, and a drainage assembly. The drainage assembly includes a water receiving tray 200, a water storage device 400, a water pump 500, and a water level detection device 300. The housing includes a front panel 100 and a rear case. The front side of the rear case is open, and the front panel 100 is detachably connected to the rear case. The water receiving tray 200, the water pump 500, and the water storage device 400 are all disposed inside the housing. The water receiving tray 200 is disposed below the indoor heat exchanger and is used to collect the condensed water generated on the surface of the indoor heat exchanger. The water receiving tray 200 has a drain port. The water storage device 400 has a water inlet 460 and a water outlet 450. The water pump 500 has an inlet 510 and an outlet 520. The water inlet 460 of the water storage device 400 is communicated with the drain port of the water receiving tray 200 to convey the water in the water receiving tray 200 into the water storage device 400. The inlet 510 of the water pump 500 is communicated with the water outlet 450 of the water storage device 400. A drain pipe is connected to the outlet 520 of the water pump 500 to drain the water in the water storage device 400 to the outside of the air conditioner indoor unit under the action of the water pump 500. The water level detection device 300 is used to detect the water level in the water receiving tray 200 to determine that the water pump 500 is faulty when the water level in the water receiving tray 200 is greater than or equal to a preset water level.

[0045] Specifically, the housing is formed with an air inlet 110 and an air outlet 120. An air heat exchange duct 600 is formed inside the housing, and the air heat exchange duct 600 is connected between the air inlet 110 and the air outlet 120. The function of the indoor heat exchanger is to transfer heat through the process of condensation or evaporation, so as to adjust the indoor temperature, humidity and air quality. Specifically, heat exchange is carried out between the air and the refrigerant in the indoor heat exchanger. In summer, the indoor temperature is reduced; in winter, the indoor temperature is increased. When the air conditioner indoor unit is working, under the action of the indoor fan, the indoor air enters the air heat exchange duct 600 from the air inlet 110; under the action of the indoor heat exchanger, heat exchange air is formed; the heat exchange air is discharged into the room through the air outlet 120.

[0046] When the air conditioner operates in the cooling mode, the indoor heat exchanger is an evaporator, and condensed water will be generated on the surface of the evaporator. The condensed water will flow downward into the water receiving tray 200, and the condensed water in the water receiving tray 200 flows into the water storage device 400 through the drain port. When the water level in the water storage device 400 is relatively high, the water pump 500 is started; under the action of the water pump 500, the water in the water storage device 400 can be discharged outside the air conditioner indoor unit through the drain pipe.

[0047] In this embodiment, on the one hand, since the front panel 100 is detachably connected to the rear case, the water level detection device 300 is arranged in the water receiving tray 200, and the upper part of the water receiving tray 200 is open. By removing the front panel 100, the water level detection device 300 can be repaired or replaced, which is convenient for operation. In addition, the water level detection device 300 can detect the water level in the water receiving tray 200. If the water level in the water receiving tray 200 is greater than or equal to the preset water level, it can prompt a failure of the water pump 500 to remind the user to turn off the air conditioner and repair the water pump, effectively preventing the occurrence of indoor water overflow. On the other hand, a water storage device 400 is added outside the water receiving tray 200 to store the water discharged from the water receiving tray 200; the water storage device 400 can increase the water storage capacity. When the water level in the water storage device 400 reaches the starting water level, the water pump 500 is started; when the water level in the water storage device 400 drops to the closing water level, the water pump 500 is closed. That is to say, after the water pump 500 is started, its running time is relatively long, and the interval time between the last closing moment and the next starting moment of the water pump 500 is relatively long. Compared with the prior art, during the refrigeration cycle of the air conditioner, the start-stop times of the water pump 500 can be reduced, so as to avoid frequently starting and stopping the water pump 500 and reducing the service life of the water pump 500.

[0048] In some alternative embodiments of the present utility model, the drain port of the water receiving tray 200 is higher than the water inlet 460 of the water storage device 400, so that the water in the water receiving tray can automatically flow into the water storage device 400.

[0049] In some alternative embodiments of the present utility model, the water storage device 400 is formed by thermoforming. Thermoforming has good forming properties and physical properties. By heating the plastic sheet to the softening temperature, fitting it on the surface of the mold and applying negative pressure, the required shape can be formed, enabling the production of complex shapes with a smooth and beautiful surface.

[0053] In some alternative embodiments, the drain port of the water receiving tray 200 is directly communicated with the water inlet 460 of the water storage device 400.

[0054] As Figure 4As shown, in some alternative embodiments of the present utility model, the water pump 500 is disposed outside the heat exchange air duct 600 in the length direction thereof, and in front of the water storage device 400. The inlet 510 of the water pump 500 is communicated with the outlet 450 of the water storage device 400 through a second connecting pipe. Specifically, the water pump 500 is located between the outer wall of the air duct wall 610 of the heat exchange air duct 600 and the inner wall of the rear case.

[0055] Furthermore, the water pump 500 is detachably connected to the channel wall of the heat exchange air duct 600. For example, the water pump 500 can be installed on the channel wall of the heat exchange air duct 600 by bolts or screws, etc. Or, the water pump 500 is detachably connected to the side wall of the housing. For example, the water pump 500 can be installed on the side wall of the housing by bolts or screws, etc. Further still, the water pump 500 is detachably connected to the lower side wall of the housing; or, the water pump 500 is detachably connected to the left side wall or the right side wall of the housing.

[0056] When the water pump 500 fails and needs to be repaired, first remove the front panel 100 from the rear case to expose the opening of the rear case; then separate the water pump 500 from the housing or the air duct wall 610 of the heat exchange air duct 600, and then pull the water pump 500 forward to the outside of the rear case, and the water pump 500 can be replaced or repaired.

[0057] In some alternative embodiments of the present utility model, the second connecting pipe is a corrugated pipe. The corrugated pipe is a metal pipe with a corrugated shape, which has the advantages of high temperature resistance, corrosion resistance, high strength, good flexibility, etc. The corrugated pipe can be bent and twisted within a certain range and can adapt to various complex pipe layouts. In some alternative embodiments, the first connecting pipe 700 can also be a plastic hose.

[0058] In some alternative embodiments of the present utility model, a first fixing clip is sleeved on the end of the second connecting pipe to improve the connection tightness and firmness between the first connecting pipe 700 and the inlet 510 of the water pump 500 and the outlet 450 of the water storage device 400.

[0059] In some alternative embodiments of the present utility model, a second fixing clip is sleeved on the inlet end of the drain pipe to improve the connection tightness and firmness between the drain pipe and the outlet 520 of the water pump 500.

[0060] When the water pump 500 fails and needs to be repaired, first separate the water pump 500 from the housing or the air duct wall 610 of the heat exchange air duct 600, use the telescopic performance of the corrugated pipe to pull the water pump 500 out of the housing, and then remove the fixing clips at the inlet 510 and the outlet 520 of the water pump 500, and the water pump 500 can be replaced or repaired.

[0061] As Figure 6As shown, in some alternative embodiments of the present utility model, the water storage device 400 includes a first part 410, a second part 420, and a third part 430 that are connected in sequence. The front surface of the second part 420 has a recess 440, and the recess 440 is adapted to the corresponding air duct wall of the heat exchange air duct 600; the first part 410 and the third part 430 are located at both ends of the heat exchange air duct 600 in the length direction. In this embodiment, the water storage device 400 surrounds the rear part of the heat exchange air duct 600, so that the water storage device 400 can have a relatively large water storage space within a limited space.

[0062] In some alternative embodiments of the present utility model, the water inlet 460 is arranged on the front side of the first part 410, and the water outlet 450 is arranged on the front side of the third part 430; the water pump 500 is arranged in front of the third part 430, and the drain outlet of the water receiving tray 200 is arranged in front of the first part 410. In some alternative embodiments, the water inlet 460 and the water outlet 450 can also be both arranged on the front side of the third part 430; alternatively, water inlets 460 are arranged on the front sides of both the first part 410 and the third part 430, and drain outlets are arranged at both ends of the water receiving tray 200 in the length direction correspondingly.

[0063] In some alternative embodiments of the present utility model, there is a slot on the rear shell, and there is a plug-in part on the front panel 100, and the plug-in part is adapted to the slot.

In some alternative embodiments, there is a plug-in part on the rear shell, and there is a slot on the front panel 100, and the plug-in part is adapted to the slot.

[0064] As Figure 1 shown, in some alternative embodiments of the present utility model, an air inlet 110 and an air outlet 120 are formed on the front panel 100. The heat exchange air duct 600 adopts a structure of forward air intake and forward air outlet, which is not restricted by the cabinet and is more convenient for the installation and use of the embedded air conditioner indoor unit.

[0065] As Figure 1 shown, in some alternative embodiments of the present utility model, the air inlet 110 is arranged above the air outlet 120, and the air outlet 120 extends along the length direction of the housing. Specifically, the housing extends in the left-right direction, and the air outlet 120 extends in the left-right direction, so that the air outlet 120 has a strip-shaped structure, and thus the air outlet 120 can have a relatively large air outlet area.

[0066] As Figure 1 shown, in some alternative embodiments of the present utility model, the area of the air inlet 110 is larger than the area of the air outlet 120.

[0067] The area of the air inlet 110 is larger than that of the air outlet 120, which can improve the efficiency of the indoor fan. Specifically, by increasing the area of the air inlet 110, the inflow of air can be effectively increased, making the indoor air circulation smoother, helping to improve the cooling or heating efficiency of the air conditioner, ensuring that the indoor temperature can reach the set value faster, and thus providing a more comfortable and efficient indoor environment.
