In the embodiment of the present invention, please refer to Fig. 1 to Fig. 4, the air conditioner indoor unit includes a housing 100 and a cleaning device, the cleaning device includes a driving device 200, a water spray pipe 300 located in the housing 100, and a One end of the water pipe 300 is connected to the water inlet pipe 400, and the outer wall of the water spray pipe 300 is provided with a plurality of water spray holes 310 arranged at intervals. The driving device 200 is connected to the water spray pipe 300 and drives the water spray pipe 300 to move along its axial direction.

The housing 100 of the indoor unit of the air conditioner has an air inlet 130 and an air outlet connected to each other to form an air duct. The housing 110 is also provided with an evaporator 110 and a wind wheel 120 . to form a wind tunnel. When the wind wheel 120 rotates, air enters through the air inlet 130 and exchanges heat with the refrigerant in the evaporator 110 , so that the heat-exchanged wind is blown out from the air outlet by the action of the wind wheel 120 . Dust or sundries usually enter the casing 100 through the air inlet 130. By setting the water spray pipe 300 in the casing 100, the water spray pipe 300 can spray water into the casing 100 to realize the inside of the casing 100. Cleaning effect. When cleaning water is delivered to the water spray pipe 300 through the water inlet pipe 400, the height of the end of the water inlet pipe 400 away from the water spray pipe 300 can be higher than the height of the water spray pipe 300. At this time, due to the effect of gravity, the water in the water inlet pipe 400 It will flow into the water spray pipe 300 by itself, so as to provide material guarantee for the subsequent water spray process. Of course, the height of the end of the water inlet pipe 400 away from the water spray pipe 300 can also be lower than the height of the water spray pipe 300. At this time, in order to overcome the influence of gravity, a water pump can be set on the water inlet channel, so that the water in the downstream part can pass through the effect of the water pump. sent to the upstream section. In addition, in order to ensure a higher water spray efficiency, the water spray pipe 300 in this embodiment is arranged in a horizontal direction, and the water spray holes 310 are arranged at intervals along the axial direction of the water spray pipe 300, so that there are suitable water spray pipes 300 When the water level is high, the effect of spraying water through all the water spray holes 310 can be realized.
