Fig. 2 and 3 are schematic views of the structure of the cleaning tube 30, which adopts a single row of straight open-hole tube structure. The length of the cleaning pipe 30 of the first cleaning part is equivalent to the length of the filter screen 20 so as to realize the all-round cleaning of the upper filter screen 20 component of the indoor unit of the air conditioner in the whole length direction. The pipeline length of the cleaning pipe 30 of the second cleaning part is equivalent to the length of the air duct, so that the air duct and the fan blade can be cleaned in all directions in the whole length direction.
When the air conditioner is cleaned, the indoor unit of the air conditioner is firstly operated to the closed state, as shown in fig. 1.
Cleaning of the filter screen 20: firstly, the winding drum 80 drives the filter screen 20 to move from the track in the horizontal direction to the track in the vertical direction; then the upper end washing device starts to spray high-speed water flow, and at the same time, the drum 80 drives the filter net 20 to gradually move from the track in the vertical direction to the track in the horizontal direction. In the process that the filter screen 20 gradually moves from the track in the vertical direction to the track in the horizontal direction, the high-speed water flow cleans all the sections of the filter screen 20, and the cleaning range of the high-speed water flow is shown in fig. 1. The cleaned water flows down to the water receiving tray 1 of the air conditioner and is discharged outdoors.
Cleaning of cross-flow fan 42, air duct (volute 41, movable volute 412, volute tongue 43 body): the movable volute 412 is lapped with the upper wall surface of the air duct to form a water retaining structure to prevent water sprayed from the lower nozzle 50 from leaking to the outside of the air conditioner. The cleaning pipe 30 of the second cleaning portion starts to spray a high-speed water flow, and the cleaning range of the high-speed water flow is shown in fig. 1. The single row of straight perforated pipes in the cleaning pipe 30 of the second cleaning part are driven by the motor to rotate 360 degrees, so that the cleaning of the whole cross flow fan 42 and the air duct (the volute body 411, the movable volute 412 and the volute tongue 43) is completed, and the water after cleaning flows to the second water receiving disc 62 through the volute 41 and the movable volute 412 and is discharged to the outside.
Drying the inside of the air conditioner: after the first cleaning part and the second cleaning part complete cleaning of the internal structure of the whole air-conditioning indoor unit, the air-conditioning indoor unit starts a heating state and starts the cross flow fan 42 to dry water on the internal structure of the air-conditioning indoor unit.
The cleaning of the indoor unit of the air conditioner is completed through the steps.
