Or, the first water pan 61, the second water pan 62, the third water pan 63 and the volute component 31 may be integrally formed, and such an arrangement is convenient for production, manufacture and processing, and also convenient for installation. Specifically, the volute assembly 31 in this embodiment includes a volute body 311 and a movable volute 312, the movable volute 312 is movably disposed on the volute body 311, and the first water collector 61, the second water collector 62, and the third water collector 63 are disposed on the volute body 311. The movable volute 312 has an avoiding position and an abutting position, and when the air conditioner indoor unit is in a normal working state, the movable volute 312 is in the avoiding position so that the air after heat exchange is blown out from the air outlet; when the indoor unit of the air conditioner is in a cleaning state, the movable volute 312 moves to a position abutting against the volute tongue 32, so that the air outlet is blocked by the movable volute 312, and the cleaned sewage is prevented from flowing out of the air outlet.

Then, the multi-directional pump is driven to suck the water source in the first water collecting tank 64 of the first water collecting tray 61 through the third interface 54, the water source is filtered and then forms high-temperature and high-pressure water vapor under the heating action of the heating module in the pump body of the multi-directional pump, and finally the water source is conveyed to the first cleaning part 41 through the fourth interface 55 and conveyed to the second cleaning part through the fifth interface 56 so as to clean the filter screen 20 through the first cleaning part 41 and clean the fan and the air duct component 30 through the second cleaning part.
The cleaning process for the filter net 20 is as follows: the reel 100 drives the filter screen 20 to move from the horizontal position to the rail 90 in the vertical direction, the nozzle of the first cleaning part 41 starts to spray steam, and the filter screen 20 staying on the rail 90 (vertical) of the filter screen 20 is cleaned, and the cleaning range of the nozzle of the first cleaning part 41 is shown in fig. 1. The cleaned water flows down into the first water receiving tray 61, and then flows into the first water collecting tank 64 of the first water receiving tray 61 from the first water receiving tray 61, and the sewage is discharged to the outside through the upper water receiving tray drain pipe.
Cleaning of the cross-flow fan 33, the air duct member 30 (the scroll body 311, the movable scroll 312, the scroll tongue 32): the lap joint of the movable volute 312 and the upper wall surface of the air duct form a water retaining structure to prevent steam sprayed by the lower spray head from leaking to the outside of the indoor unit of the air conditioner. The nozzle of the second cleaning part sprays steam, and the cleaning range is shown in fig. 1. The cleaned water flows to the lower water collecting tray along the inner wall surface of the air duct (the scroll body 311, the movable scroll 312, the scroll throat, etc.), and then flows from the lower water collecting tray into the second water collecting tank 65 through the lower water collecting tray water discharge hole 67, and a sealing cover plate 66 is covered above the second water collecting tank 65. The first connector 52 of the multi-directional pump is arranged at the lower end of the second water collecting tank 65 of the second water collecting tray 62 and is used for sucking and cleaning sewage after the air duct and the fan blades are cleaned. The second connector 53 is connected with a siphon pipe of a second water receiving tray 62 and is used for discharging sewage.
The second water collecting tank 65 has two sewage discharge modes: sewage may be drawn from the first port 52 by a multi-directional pump drive as a power source to discharge the sewage from the second port 53. The cam 81 is driven by the siphon motor on the second water receiving tray 62 to move, so that the siphon is squeezed, negative pressure is formed in the siphon, sewage is sucked from the first connector 52 of the multi-directional pump under the action of the negative pressure, flows into the siphon through the second connector 53 and is finally discharged out of a room.
Normally, the second catch basin 65 is drained of the contaminated water in the second way, and when the suction capacity of the siphon tube for the contaminated water is insufficient, the first way (pump driven, powered) is used to drain the contaminated water.
In order to avoid that the sewage blocks the drainage channel due to insufficient negative pressure capability after the second drainage mode is used for a long time, the first drainage mode is preferably switched after the second drainage mode is adopted for N times, and the drainage mode is switched by taking the first drainage mode as one period. In order to reduce the risk of blockage, N is less than or equal to 8, and preferably 5 is taken.
After the cleaning is finished, drying the interior of the air conditioner indoor unit: after the upper nozzle and the lower nozzle finish cleaning the whole air conditioner, the air conditioner is started to be in a heating state, the cross flow fan 33 is started, and water on the internal structure of the air conditioner is dried.
The cleaning of the air conditioner indoor unit is completed through the steps.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects: by adopting the distributed steam automatic cleaning technology, the filter screen and the air duct component are efficiently cleaned, the cleaning range is greatly expanded, and the internal structure of the indoor unit of the air conditioner can be thoroughly cleaned. Adopts a multi-directional pump to provide a cleaning water source, generate high-temperature water vapor through a heating part in a pump body and discharge sewage. The structure that a plurality of water receiving discs are combined with a siphon and a drain pipe is adopted, and the problem of sewage drainage after cleaning is solved. The first water pan (the sewage flows to the first water pan after the filter screen is cleaned) drains water through the first drainage pipe, and the second water pan (the sewage flows to the second water pan after the fan blade and the air duct are cleaned) drains water by adopting a siphon or a pump body.
