[0042] Figure 1 is a schematic structural diagram of an air conditioner indoor unit 100 according to an embodiment of the present utility model, as Figure 1 shown, and referring to Figures 2 to 4 an embodiment of the present utility model provides an air conditioner indoor unit. The air conditioner indoor unit includes a housing 100, an indoor heat exchanger, and a drainage assembly. The drainage assembly includes a water receiving tray 200, a water storage device 300, a water pump 400, and a drainage pipe.

[0043] The housing 100 is formed with an air inlet 110 and an air outlet 120. A heat exchange air duct 500 is formed inside the housing 100, and the heat exchange air duct 500 is connected between the air inlet 110 and the air outlet 120. The indoor heat exchanger is disposed in the heat exchange air duct 500; the water receiving tray 200 is disposed below the indoor heat exchanger and is used for collecting the condensed water generated on the surface of the indoor heat exchanger. The water storage device 300 is disposed outside the heat exchange air duct 500, and the water inlet 310 of the water storage device 300 is communicated with the drain outlet 210 of the water receiving tray 200; the water pump 400 is disposed outside the heat exchange air duct 500, and the inlet 410 of the water pump 400 is communicated with the outlet 320 of the water storage device 300 through a first connecting pipe, and a drain pipe is connected to the outlet 420 of the water pump 400.

[0044] Specifically, the function of the indoor heat exchanger is to transfer heat through the process of condensation or evaporation to adjust the indoor temperature, humidity and air quality. Specifically, heat exchange is performed between the air and the refrigerant inside 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 operating, under the action of the indoor fan, the indoor air enters the heat exchange air duct 500 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. The water pump 400 is located between the outer wall of the air duct wall 510 of the heat exchange air duct 500 and the inner wall of the housing 100.

[0045] 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 300 through the drain outlet 210. When the water level in the water storage device 300 is relatively high, the water pump 400 is started; under the action of the water pump 400, the water in the water storage device 300 can be discharged outside the air conditioner indoor unit through the drain pipe.

[0046] In this embodiment, a water storage device 300 is added outside the water receiving tray 200 to store the water in the water receiving tray 200; the water pump 400 is connected to the water receiving tray 200 through the water storage device 300. On the one hand, the water pump 400 is disposed outside the heat exchange air duct 500 and is located outside the water receiving tray 200 and the water storage device 300, so that the water pump 400 can be conveniently repaired and replaced. On the other hand, by providing the water storage device 300, the water storage capacity can be increased. When the water in the water storage device 300 reaches a certain amount, the water pump 400 is started. During the cooling cycle of the air conditioner, the operating time of the water pump 400 can be shortened, thereby reducing the noise generated by the operation of the water pump 400 and improving the user experience.

[0047] Such as Figure 3 and Figure 4As shown, in some alternative embodiments of the present utility model, the water outlet 320 of the water storage device 300 is arranged at the lower part of the water storage device 300, and the water outlet 320 of the water storage device 300 is higher than the inlet 410 of the water pump 400. In some alternative embodiments, the water outlet 320 of the water storage device 300 is at the same height as the inlet 410 of the water pump 400. The embodiment where the water outlet 320 of the water storage device 300 is higher than the inlet 410 of the water pump 400 is more conducive to emptying the water in the water storage device 300 to avoid or reduce the residual water in the water storage device 300.

[0048] In some alternative embodiments of the present utility model, the water pump 400 is detachably connected to the channel wall of the heat exchange air duct. For example, the water pump 400 can be installed on the channel wall of the heat exchange air duct by bolts or screws, etc.

[0049] In some alternative embodiments of the present utility model, the water pump 400 is detachably connected to the side wall of the housing 100. For example, the water pump 400 can be installed on the side wall of the housing 100 by bolts or screws, etc. Further, the water pump 400 is detachably connected to the lower side wall of the housing 100; or, the water pump 400 is detachably connected to the side wall of the housing 100 on the side close to the drain port 210 of the water receiving tray 200.

[0050] In some alternative embodiments of the present utility model, the first 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 can also be a plastic hose.

[0051] In some alternative embodiments of the present utility model, a first fixing clip is sleeved on the end of the first connecting pipe to improve the connection tightness and firmness between the first connecting pipe and the inlet 410 of the water pump 400 and the water outlet 320 of the water storage device 300.

[0052] In some alternative embodiments of the present utility model, a second fixing clip is sleeved on the water inlet end of the drain pipe to improve the connection tightness and firmness between the drain pipe and the outlet 420 of the water pump 400.

[0053] When the water pump 400 fails and needs to be repaired, first separate the water pump 400 from the housing 100 or the air duct wall 510 of the heat exchange air duct 500, use the telescopic performance of the corrugated pipe to pull the water pump 400 out of the housing 100, and then remove the fixing clips at the inlet 410 and outlet 420 of the water pump 400, then the water pump 400 can be replaced or repaired.

[0054] Such as Figure 3 And Figure 4As shown, in some alternative embodiments of the present utility model, the indoor heat exchanger extends along the length direction of the housing 100, and the water receiving tray 200 extends along the length direction of the housing 100. The drain port 210 of the water receiving tray 200 is provided at one end in the length direction of the water receiving tray 200, and the drain port 210 of the water receiving tray 200 communicates with the water inlet 310 of the water storage device 300 through a second connecting pipe. The water pump 400 and the water storage device 300 are arranged below the side of the water receiving tray 200.

[0055] In this embodiment, the drain port 210 of the water receiving tray 200 is provided at one end in the length direction of the water receiving tray 200, so that the drain port 210 is outside the heat exchange air duct 500, which facilitates the installation of the second connecting pipe.

[0056] As Figure 3 shown, in some alternative embodiments of the present utility model, the water pump 400 and the water storage device 300 are distributed in the front-rear direction.

[0057] In some alternative embodiments of the present utility model, the water pump 400 and the water storage device 300 are arranged behind the heat exchange air duct 500.

[0058] As Figures 1 to 4 shown, in some alternative embodiments of the present utility model, the housing 100 includes a front panel 130 and a rear housing 140. The front side of the rear housing 140 is open, and the front panel 130 is detachably connected to the rear housing 140. The water pump 400 is arranged in front of the water storage device 300. When the water pump 400 fails and needs to be repaired, first remove the front panel 130 from the rear housing 140 to expose the opening of the rear housing 140; then separate the water pump 400 from the housing 100 or the air duct wall 510 of the heat exchange air duct 500, then remove the fixing clips at the water inlet 410 and the water outlet 420 of the water pump 400, and pull the water pump 400 forward to the outside of the rear housing 140, and the water pump 400 can be replaced or repaired.

[0059] As Figure 4 shown, in some alternative embodiments of the present utility model, the water storage device 300 includes a first section 330 and a second section 340 that are connected in sequence. The first section 330 is arranged at one end in the length direction of the heat exchange air duct, and the second section 340 is arranged at the rear side of the heat exchange air duct. The first section 330 and the second section 340 form an L-shaped structure. In some alternative embodiments, the water storage device 300 can also be other structures; for example, the water storage device 300 can be only located at one end in the length direction of the heat exchange air duct, or the water storage device 300 is only located at the rear side of the heat exchange air duct.

[0060] The water storage device 300 is distributed in an L shape, utilizing the rear area and end area of the heat exchange air duct 500, so that the water storage device 300 has a relatively large accommodation space. Only when the water level in the water storage device 300 reaches a certain height, it is necessary to start the water pump 400, thereby avoiding frequent start and stop of the water pump 400 and improving the service life of the water pump 400.

[0061] As Figure 4 shown, in some alternative embodiments of the present utility model, the upper end of the water storage device 300 is open to form the water inlet 310 of the water storage device 300.

[0062] In some alternative embodiments of the present utility model, the water storage device 300 is a closed structure, and the water inlet of the water storage device 300 is arranged on the top or side wall of the water storage device 300. The water inlet of the water storage device 300 is higher than the water outlet of the water storage device 300.

[0063] As Figure 1 and Figure 2 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 130. The heat exchange air duct 500 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.

[0064] Furthermore, a slot is provided on the rear shell 140, and a plug-in part is provided on the front panel 130. The plug-in part is adapted to the slot. When the plug-in part is inserted into the slot, the detachable connection between the front panel 130 and the rear shell 140 can be realized.

[0065] As Figure 1 and Figure 2 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 100. Specifically, the housing 100 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, thereby enabling the air outlet 120 to have a relatively large air outlet area.

[0066] 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 of the air conditioner 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. In addition, the above design can also effectively avoid the problem of the decrease in the air flow velocity caused by the too large size of the air outlet 120, keeping the air flow velocity within a suitable range, and thus improving the user experience and comfort level.

[0068] As Figure 3 and Figure 4 shown, in some alternative embodiments of the present invention, a water level detection device 600 is provided in the water storage device 300 for detecting the water level in the water storage device 300. During the refrigeration operation of the air conditioner, the start or stop of the water pump 400 can be controlled according to the water level in the water storage device 300, so as to reduce the operation time of the water pump 400 as much as possible.

[0069] In some alternative embodiments of the present invention, the water level detection device is an ultrasonic water level gauge, which uses ultrasonic technology to measure the water level and determines the water level through the principle of sound wave reflection at different interfaces. The ultrasonic water level gauge has the characteristics of high precision and fast response.

[0070] In some alternative embodiments of the present invention, the water level detection device is a radar water level gauge, which uses radar technology to measure the water level and measures the water level height by emitting radar waves and receiving their reflected signals.

[0071] In some alternative embodiments of the present invention, the water level detection device 600 is a float switch. The working principle of the float switch is to trigger or cancel the signal output through the rise and fall of the liquid level. The float switch has the advantages of a wide application range, various installation forms, stable and reliable performance, safety and convenience, strong anti-interference ability, simple structure, convenient installation, and low maintenance cost.

[0072] In some alternative embodiments of the present invention, the air conditioner indoor unit is an embedded air conditioner indoor unit, which can be installed in a cabinet. The advantages of the embedded air conditioner indoor unit mainly include saving indoor space, being beautiful and clean, and having low noise. Specifically, the embedded air conditioner indoor unit can save indoor space, making our space more spacious, reducing those complicated devices and lines, integrating the embedded air conditioner with the wall or furniture, and making the room more beautiful and clean. The embedded air conditioner indoor unit runs with low noise, which can improve the user experience. These advantages make the embedded air conditioner indoor unit an ideal choice for modern homes and commercial places.

[0073] In some alternative embodiments of the present utility model, the indoor air conditioner is a wall-mounted indoor air conditioner, which has the advantages of convenient installation and convenient relocation.

[0074] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived based on the content disclosed in the present utility model without departing from the spirit and scope of the present utility model.
