The indoor unit of the air conditioner further comprises a heat exchanger and a fan 200, wherein the heat exchanger is arranged on the chassis 100, an air inlet hole is formed in the upper portion or the front portion of the heat exchanger in the shell, and the fan 200 is arranged in an air duct of the installation space. Under the action of the fan 200, the air duct forms negative pressure, drives air in the indoor environment to enter the installation space from the air inlet, and passes through the heat exchanger to exchange heat, and the air after heat exchange is blown out into the indoor environment again through the air duct. The air in the indoor environment is circulated to realize the adjustment of parameters such as temperature, humidity and the like of the indoor environment.

It will be appreciated that in the cooling mode, the indoor unit of the air conditioner is an evaporator, and a large amount of condensed water is generated during operation, so that the base pan 100 is provided with a first water tank 110 and a second water tank 120 for receiving the condensed water of the heat exchanger. The first water tank 110 is located below the side of the heat exchanger close to the top and is used for collecting condensed water flowing down from the side of the heat exchanger close to the top, and the second water tank 120 is located below the side of the heat exchanger far away from the top and is used for collecting condensed water flowing down from the side of the heat exchanger far away from the top. Since the indoor unit of the wall-mounted air conditioner is of a long-strip type, the heat exchanger is also designed to be of a long strip type accordingly, and in order to facilitate receiving of condensed water, the first water tank 110 extends in the left-right direction shown in fig. 1, and the second water tank 120 extends in the left-right direction shown in fig. 1.

In order to rapidly discharge condensed water out of the indoor unit of the air conditioner, as shown with reference to fig. 2, 3 and 4, the first water tank 110 is configured to be disposed obliquely downward from the left and right sides toward the middle, and the second water tank 120 is configured to be disposed obliquely downward from the left and right sides toward the middle. It will be appreciated that the first water tank 110 includes a bottom wall, left and right side walls located at both sides in the left-right direction, and front and rear side walls located in the front-rear direction, and a plurality of wall surfaces form a water storage chamber. The bottom wall can be a plane, an arc surface, a V-shaped surface and the like, is not particularly limited, is respectively arranged downwards from the left side and the right side to the middle part in an inclined manner, and has a structure with low middle and high two sides, so that condensed water dropped into the first water tank 110 by the heat exchanger can smoothly flow to the middle part of the first water tank 110 from the left side and the right side of the first water tank 110, the drainage distance of condensed water on the first water tank 110 is shortened, the drainage efficiency is improved, and the situation that the condensed water freezes and ponds in the flowing process due to the long drainage distance of an air conditioner indoor unit in the prior art is avoided; and the water trapping phenomenon is effectively avoided on the left side and the right side of the first water tank 110, so that bacteria are prevented from breeding. The second water tank 120 is similar to the first water tank 110 in structure, and it can be understood with reference to the above description of the structure of the first water tank 110, so that condensed water dropping into the second water tank 120 from the heat exchanger can smoothly flow to the middle of the second water tank 120 from the left side and the right side of the second water tank 120, shortening the drainage distance of the condensed water on the second water tank 120, and improving the drainage efficiency.

Referring to fig. 2, it can be appreciated that the chassis 100 is further provided with a diversion channel 130, and the diversion channel 130 is used to communicate the first water tank 110 and the second water tank 120. In order to ensure the smoothness of the drainage of the condensed water, the two ends of the diversion channel 130 are respectively communicated with the middle part of the first water tank 110 and the middle part of the second water tank 120, so that the condensed water collected by the first water tank 110 and the condensed water collected by the second water tank 120 are conveniently converged in the diversion channel 130, and are conveniently and uniformly discharged out of the indoor unit of the air conditioner. It should be noted that, the diversion channel 130 may be a groove body or a tube body, and is specifically selected according to the structure requirement of the indoor unit of the air conditioner, which is not limited herein.

Referring to fig. 2 and 4, the air conditioning indoor unit further includes a drain passage 300, and the drain passage 300 is used to drain condensed water out of the air conditioning indoor unit. The drain channel 300 is fixedly connected with the chassis 100, the drain channel 300 is provided with a drain hole 311, the drain hole 311 can be communicated with the middle part of the second water tank 120 or communicated with the diversion channel 130, and condensed water gathered in the middle part of the second water tank 120 and the lower end part of the diversion channel 130 can flow out through the drain hole 311 of the drain channel 300. It is understood that, in order to realize the communication between the drain hole 311 and the diversion channel 130, the drain hole 311 may be disposed at a connection portion between the diversion channel 130 and the second water tank 120, may be disposed at a lowest portion of the diversion channel 130, or may be disposed at a middle portion of the second water tank 120.

According to the embodiment of the utility model, the first water tank 110 and the second water tank 120 of the chassis 100 for receiving condensed water are arranged in a structure of inclining downwards from the left side and the right side to the middle, the chassis 100 is also provided with the diversion channel 130 which is communicated with the middle of the first water tank 110 and the middle of the second water tank 120, so that condensed water of the first water tank 110 and the second water tank 120 can be quickly collected in the middle of the second water tank 120 or the diversion channel 130, the drainage channel 300 is communicated with the middle of the second water tank 120 or the diversion channel 130 through the drainage hole 311, and the drainage channel 300 discharges condensed water out of the indoor unit of the air conditioner, thereby shortening the drainage distance of the condensed water on the first water tank 110 and the second water tank 120 and improving the drainage efficiency of the condensed water.

Because the air conditioner indoor unit in the prior art adopts left side or right side drainage, in order to ensure the smoothness of drainage, the air conditioner indoor unit needs to be obliquely installed towards the drainage side when being installed, the rolling force generated by the inclination angle is required to be larger than the surface tension of water, when the inclination angle is too small, drainage difficulty can occur, and condensed water overflows to cause the wall surface to be wet and moldy; when the inclination is too large, the actual water storage height of the water tank is smaller than the designed water storage height, and the water storage capacity of the water tank is reduced. Compared with the prior art, the embodiment of the utility model shortens the drainage stroke by half, so that the indoor unit of the air conditioner does not need to be obliquely installed during installation, and the installation difficulty is reduced. Moreover, because the drainage stroke is short, the inclination angles of the first water tank 110 and the second water tank 120 can be designed to be larger, so that the rolling force is larger than the surface tension of the condensed water, the condensed water can be quickly drained out of the machine body, and the chassis 100 is prevented from being condensed.

Referring to fig. 4, it can be understood that the bottom wall 122 of the second water tank 120 has an angle phi with respect to the horizontal plane, where phi satisfies: phi is more than 0 DEG and less than or equal to 5 deg. When the above parameter ranges are satisfied, the second water tank 120 has a better drainage effect from the left and right sides to the middle. When the included angle phi is too large, the water storage capacity of the water storage cavity of the second water tank 120 is reduced, and the risk of overflow of condensed water exists; if the above problem is overcome by enlarging the side wall of the second water tank 120, there is a problem in that the overall size is increased. It is understood that the included angle between the bottom wall of the first water tank 110 and the horizontal plane is greater than 0 ° and less than or equal to 5 °. When the above parameter ranges are satisfied, the first water tank 110 has a better drainage effect from the left and right sides to the middle.
