[0052] Figure 1 Schematic diagram of the structure of an air conditioner indoor unit according to an embodiment of the present invention. Figure 1 As shown, and reference Figures 2 to 6 An embodiment of the present invention provides an air-conditioning indoor unit, which includes a shell, an indoor heat exchanger and a drainage assembly. The drainage assembly includes a water receiving tray 200, a water storage tank 400, a water pump 500 and a water level detection device 300.

[0053] The water pan 200, water pump 500, and water tank 400 are all housed within the housing. The water pan 200 is located below the indoor heat exchanger to collect condensed water generated on the surface of the indoor heat exchanger. The water pan 200 has a drain outlet, the water tank 400 has an inlet 460 and an outlet 450, and the water pump 500 has an inlet 510 and an outlet 520. The inlet 460 of the water tank 400 communicates with the drain outlet of the water pan 200, transferring water from the water pan 200 to the water tank 400. The inlet 510 of the water pump 500 communicates with the outlet 450 of the water tank 400, while the outlet 520 of the water pump 500 is connected to a drain pipe. Under the action of the water pump 500, the water in the water tank 400 is drained through the drain pipe to the outside of the air conditioner indoor unit. The water tank has a mounting hole formed in the mounting hole, which is provided with a mounting cover 470. The water level detection device 300 is installed on the installation cover 470 and extends into the water tank 400 to detect the water level in the water tank 400. The air conditioner can control the start or stop of the water pump 500 according to the water level in the water tank 400.

[0054] Specifically, the shell is formed with an air inlet 110 and an air outlet 120, and a heat exchange duct 600 is formed in the shell, and the 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 to regulate the indoor temperature, humidity and air quality. Specifically, the air is heat-exchanged with the refrigerant in the indoor heat exchanger. In summer, the indoor temperature is lowered; 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 heat exchange duct 600 from the air inlet 110; under the action of the indoor heat exchanger, heat exchange air is formed; and the heat exchange air is discharged into the room through the air outlet 120.

[0055] When the air conditioner is operating in cooling mode, the indoor heat exchanger serves as the evaporator, and condensation forms on its surface. This condensation flows down into the water tray 200, where it flows through the drain port into the water tank 400. When the water level in the water tank 400 is high, the water pump 500 is activated, draining the water from the water tank 400 through the drain pipe to the outside of the air conditioner's indoor unit.

[0056] In this embodiment, a water tank 400 is added outside the water tray 200 to store water discharged from the tray 200. This increases the water storage capacity of the water tank 400. When the water level in the water tank 400 reaches the start level, the water pump 500 is started; when the water level in the water tank 400 drops to the shut-off level, the water pump 500 is shut off. This means that after the water pump 500 is started, it runs for a longer time, and the interval between the last time the water pump 500 is shut off and the next time it is started is longer. Compared to the prior art, this embodiment reduces the number of starts and stops of the water pump 500 during the air conditioner's cooling cycle, thereby avoiding frequent starts and stops that reduce the service life of the water pump 500. During assembly, the water level detection device 300 is first installed below the mounting cover 470. The water level detection device 300 is then inserted into the water tank 400 through the mounting hole, and the mounting cover 470 is placed over the mounting hole. The installation method of the water level detection device 300 is simple and easy to operate, and can maintain the sealing of the water tank 400.

[0057] In some optional embodiments of the present invention, a mounting hole is formed at an upper position of the peripheral wall of the water tank, and the mounting cover 470 can be adhered to or screwed to the mounting hole.

[0058] In some optional embodiments of the present invention, such as Figure 3As shown, a mounting hole is formed in the top of the water tank 400, and a mounting cover 470 is provided over the mounting hole. In this embodiment, the mounting hole is provided in the top of the water tank 400. During assembly, the mounting cover 470 only needs to be placed over the mounting hole to achieve sealing of the mounting hole.

[0059] In some optional embodiments of the present invention, such as Figure 6 As shown, a mounting hole is formed at the top of the water tank, and a mounting cover 470 is provided over the mounting hole. The mounting cover 470 has a threaded hole, and the water level detection device is mounted on the lower portion of the connecting rod 310. The upper portion of the connecting rod 310 has a threaded section that is threadedly connected to the threaded hole.

[0060] During assembly, the threaded section of the connecting rod 310 is threadedly connected to the threaded hole of the mounting cover 470. The lower end of the connecting rod 310 is then inserted into the water tank 400 through the mounting hole, and the mounting cover 470 is placed over the mounting hole. In this embodiment, the mounting cover 470 is detachably connected to the connecting rod 310, making it easier to replace or repair the water level detection device 300.

[0061] Furthermore, if Figure 6 As shown, the lower end of the connecting rod 310 is detachably connected or fixedly connected to the water level detection device 300. Preferably, the lower end of the connecting rod 310 is threadedly connected to the water level detection device 300.

[0062] like Figure 6 As shown, in some optional embodiments of the present invention, the threaded section of the connecting rod 310 is threadedly connected to an upper nut 320 and a lower nut 330, which are respectively positioned above and below the mounting cover 470. In this embodiment, the provision of the upper nut 320 and the lower nut 330 further secures the connection between the connecting rod 310 and the mounting cover 470. Furthermore, the provision of the upper nut 320 and the lower nut 330 allows the connecting rod 310 to be vertically restrained to prevent it from moving up and down. This, in turn, allows the water level detection device 300 to be vertically restrained, thereby improving the accuracy of water level detection device 300 inspections.

[0063] like Figure 4 and 6As shown, in some optional embodiments of the present invention, a protrusion 480 is formed on the top of the water tank, a mounting hole is formed in the protrusion 480, and the mounting cover 470 is threadedly connected to the protrusion 480. Specifically, the mounting cover 470 includes a cover body and a lower flange, which is integrally provided on the outer periphery of the cover body. The inner wall of the lower flange is provided with an internal thread, and the outer periphery of the protrusion 480 is provided with an external thread, which mates with the internal thread. During assembly, the mounting cover 470 is twisted onto the protrusion 480 to achieve a threaded connection between the mounting cover 470 and the protrusion 480. Compared to the above-mentioned embodiment in which the mounting cover 470 is directly placed on the mounting hole, this embodiment can improve the installation security between the mounting cover 470 and the water tank 400, thereby preventing the mounting cover 470 from shaking during transportation.

[0064] In some optional embodiments of the present invention, the drain outlet of the water receiving tray 200 is connected to the water inlet of the water storage tank 400 via a first connecting pipe 700, thereby forming a sealed passage between the water receiving tray 200 and the water storage tank 400. During use of the indoor unit, the first connecting pipe can be replaced regularly to ensure a tight seal between the drain outlet of the water receiving tray and the water inlet of the water storage tank. In some alternative embodiments, the drain outlet of the water receiving tray is directly connected to the water inlet of the water storage tank.

[0065] In some optional embodiments of the present invention, the inlet 510 of the water pump 500 is connected to the water outlet 450 of the water tank 400 via a second connecting pipe, thereby forming a sealed passage between the water pump 500 and the water tank 400. During use of the indoor unit, the second connecting pipe can be regularly replaced to ensure the seal between the water pump inlet and the water tank outlet. In some alternative embodiments, the water pump inlet is directly connected to the water tank outlet.

[0066] In some optional embodiments of the present invention, the drain outlet of the water receiving tray 200 is set at the bottom of the water receiving tray. The water inlet 460 of the water storage tank 400 is lower than the drain outlet of the water receiving tray 200, so that the water in the water receiving tray 500 can automatically flow into the water storage tank 400.

[0067] In some optional embodiments of the present invention, the water outlet 450 of the water tank 400 is lower than the water inlet 460 of the water tank 400. In other words, the water outlet 450 is located at the lower portion of the water tank 400. This facilitates draining the water from the water tank after the air conditioner is turned off, thereby reducing residual water in the water tank.

[0068] In some optional embodiments of the present invention, the water tank 400 is located outside the heat exchange duct 600 on a side away from the air outlet 120, and the water tank 400 extends along the length of the housing. This embodiment cleverly utilizes the gap between the heat exchange duct and the housing, allowing the water tank to have a larger water storage space without substantially increasing the overall size of the air conditioner indoor unit. In some alternative embodiments, the water tank 400 can also have other shapes, such as being located outside the heat exchange duct 600 in the length direction; or, the water tank 400 can be L-shaped, including a first water storage section and a second water storage section connected in sequence, with the first water storage section extending in the front-to-back direction and the second water storage section extending along the length of the housing. The shape of the water tank 400 can be designed accordingly based on the model of the air conditioner and the size of the internal space.

[0069] In some optional embodiments of the present invention, the air outlet 120 is disposed on the front side of the housing, and the water storage tank 400 is located below and behind the heat exchange duct 600. The air inlet 110 is disposed on the front side of the housing and is located above the air outlet 120. The front edge of the water tray 200 is adjacent to the air inlet 110.

[0070] In this embodiment, the heat exchange air duct 600 adopts a front air inlet and outlet structure, is not restricted by cabinet obstruction, and can be more convenient for the installation and use of the embedded air conditioner indoor unit.

[0071] Because the water pump is a centrifugal pump, a small amount of water will remain in the water tank after the air conditioner is turned off. This residual water will form water vapor. Due to the closed structure of the water tank, most of the water vapor will flow through the water inlet of the water tank, the drain outlet of the water tray, and then into the water tray, and finally out through the air inlet. Compared with open water storage devices, closed water tanks can prevent the cabinet from mold caused by increased humidity at the rear of the cabinet.

[0072] like Figure 1 and Figure 3 As shown, in some optional embodiments of the present invention, a drain port is provided at one end of the water receiving tray 200 in the longitudinal direction, and the water inlet 460 of the water storage tank 400 is provided corresponding to the drain port. The drain port is provided at the end of the water receiving tray, which can facilitate the connection between the water storage tank and the water receiving tray.

[0073] The water pump 500 is located outside the heat exchange duct 600 along its length and in front of the water tank 400. In other words, the water pump 500 is located in the gap between the end of the heat exchange duct 600 and the housing. The separation of the water pump 500 from the water tank 400 facilitates maintenance or replacement.

[0074] In some alternative embodiments of the present invention, the water pump and the water storage tank may also be disposed behind the heat exchange air duct.

[0075] like Figure 1 As shown, in some optional embodiments of the present invention, the housing includes a front panel 100 and a rear housing, the front side of the rear housing is open, and the front panel and the rear housing are detachably connected. After the front panel is removed from the rear housing, the components in the housing can be easily repaired or replaced.

[0076] In some embodiments, the rear housing is provided with a slot, and the front panel 100 is provided with a plug-in portion that fits into the slot. When the plug-in portion is inserted into the slot, the front panel 100 and the rear housing are detachably connected. In some alternative embodiments, the rear housing is provided with a plug-in portion, and the front panel 100 is provided with a slot that fits into the slot.

[0077] In some optional embodiments of the present invention, the water pump 500 can be detachably connected to the channel wall of the heat exchange duct 600. For example, the water pump 500 can be installed on the channel wall of the heat exchange duct 600 by bolts or screws.

[0078] In some optional embodiments of the present invention, the water pump 500 can be detachably connected to a side wall of the housing. For example, the water pump 500 can be mounted to the side wall of the housing using bolts or screws. Furthermore, the water pump 500 can be detachably connected to the lower side wall of the housing; or the water pump 500 can be detachably connected to the left or right side wall of the housing.

[0079] When the water pump 500 fails and needs to be repaired, first remove the front panel 100 from the rear shell to expose the opening of the rear shell; then separate the water pump 500 from the shell 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 shell to replace or repair the water pump 500.

[0080] In some optional embodiments of the present invention, the water tank 400 is formed using vacuum molding. This method offers excellent molding and physical properties. By heating a plastic sheet to its softening temperature, applying it to a mold surface, and applying negative pressure, the desired shape can be formed. This allows for the creation of complex shapes with a smooth and aesthetically pleasing surface. This ensures that the water tank 400 exhibits excellent wear resistance, impact resistance, and chemical resistance, meeting the requirements of various operating environments.

[0081] like Figure 4As shown, in some optional embodiments of the present invention, the water tank 400 includes a first portion 410, a second portion 420, and a third portion 430 connected in sequence. The front surface of the second portion 420 has a recess 440 that mates with the corresponding duct wall of the heat exchange duct 600. The first portion 410 and the third portion 430 are located at opposite ends of the heat exchange duct 600 in the longitudinal direction. In this embodiment, the water tank 400 is positioned around the rear portion of the heat exchange duct 600, thereby providing a large water storage capacity within a limited space.

[0082] In some optional embodiments of the present invention, such as Figure 4 As shown, the water inlet 460 is provided on the front side of the first portion 410, and the water outlet 450 is provided on the front side of the third portion 430; the water pump 500 is provided in front of the third portion 430, and the drain outlet of the water receiving tray 200 is provided in front of the first portion 410. In some alternative embodiments, the water inlet 460 and the water outlet 450 may both be provided on the front side of the third portion 430; or, the water inlet 460 may be provided on the front side of both the first portion 410 and the third portion 430, and drain outlets may be provided at both ends of the length direction of the corresponding water receiving tray 200.

[0083] In some optional embodiments of the present invention, the water level detection device 300 is an ultrasonic water level meter, which uses ultrasonic technology to measure water level, and determines the water level by the principle of sound waves reflecting off different interfaces. Ultrasonic water level meters are characterized by high accuracy and fast response.

[0084] In some optional embodiments of the present invention, the water level detection device 300 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.

[0085] In some optional embodiments of the present invention, the water level detection device 300 is a float switch. The operating principle of a float switch is to trigger or cancel a signal output based on the rise and fall of the liquid level. Float switches offer advantages such as wide applicability, diverse installation options, stable and reliable performance, safety and convenience, strong anti-interference capabilities, simple structure, easy installation, and low maintenance costs.

[0086] In some optional embodiments of the present invention, the air conditioner indoor unit is a built-in unit that can be installed within a cabinet.
