It can be understood that the cleaning method of the air-conditioning indoor unit provided by the present invention is completed based on the air-conditioning indoor unit provided by the above embodiment of the present invention, the cleaning mechanism may rotate synchronously with the rotating volute relative to the casing, when the rotating volute is in the first state, the rotating volute is rotated and then disposed toward the cross-flow wind wheel, that is, the cleaning mechanism is also disposed toward the cross-flow wind wheel, and performs spray cleaning on the cross-flow wind wheel, when the rotating volute is in the second state, that is, after the cleaning mechanism completes cleaning the cross-flow wind wheel, the rotating volute rotates to close the cleaning window, and the cleaning mechanism is located outside the casing, that is, rotates to the outside of the casing away from the cross-flow wind wheel; therefore, the cross-flow wind wheel can be cleaned, the interior of the indoor unit of the air conditioner can be cleaned, the health of a user can be protected, the cleaning mechanism can be prevented from forming wind resistance in the shell, and the normal operation of the indoor unit of the air conditioner can be guaranteed
Further, before the cross-flow wind wheel is controlled to rotate reversely in the step S11, the wind shield and the wind sweeping blade of the indoor unit of the air conditioner are also controlled to be closed; meanwhile, the rotating speed n of the cross-flow fan is 200-600 r/min; preferably, the optimum rotating speed n of the cross-flow fan is 300 r/min. The wind shield and the wind sweeping blades are controlled to be closed, the washing reagent can be prevented from accidentally flowing out from the air outlet to a certain degree, the washing reagent can be effectively thrown onto the evaporator by controlling the rotating speed of the cross flow fan, and the cleaning effect of the cleaning method of the indoor unit of the air conditioner is guaranteed.
The step 12 specifically includes:
s121, controlling the cleaning mechanism to spray the detergent, and controlling the spraying time of the detergent to be 0.5-2.0 min;
s122, controlling the cleaning mechanism to spray the cleaning agent, and controlling the spraying time of the cleaning agent to be 2.0-10.0 min;
wherein, the spraying time of the detergent in the step S121 is preferably 1.0 min.
It can be understood that the cleaning effect of the cross-flow wind wheel is further ensured by controlling the spraying time of the detergent and the spraying time of the cleaning agent.
After the cleaning water is sprayed, the cleaning mechanism is reset to recover the normal operation position, and the spray head is hidden outside the rear volute, so that the normal use of the air conditioner is not influenced, and the wind resistance is not generated; after the resetting of the cleaning mechanism is completed, the evaporator self-cleaning function is started to complete heating and drying; further, the air conditioner may be normally used after the step S14 is completed; furthermore, dust in the air duct can be observed and tested to be clean, and the cleaning effect of the indoor unit of the air conditioner is further improved.
In summary, the present invention provides an indoor unit of an air conditioner, an air conditioner and a cleaning method for the indoor unit of the air conditioner, where the indoor unit of the air conditioner includes an evaporator, and the indoor unit of the air conditioner further includes: a housing having a cleaning fixture window; the cross-flow wind wheel is arranged in the shell; the rotary volute is rotatably arranged on the cleaning fixed window; the cleaning mechanism is arranged on one side, away from the cross-flow wind wheel, of the rotary volute; when the cleaning fixed window is opened by the rotary volute, the rotary volute is arranged towards the cross-flow wind wheel. It can be understood that the cleaning mechanism is arranged on one side of the rotary volute, which is far away from the cross-flow wind wheel, by arranging the cleaning fixed window on the shell and rotationally arranging the rotary volute on the cleaning fixed window, and the position of the cleaning mechanism relative to the shell and the cross-flow wind wheel can be adjusted by rotating the rotary volute; when the cross-flow wind wheel needs to be cleaned, the rotating volute opens a cleaning fixed window, and at the moment, the rotating volute faces the cross-flow wind wheel, namely the cleaning mechanism faces the cross-flow wind wheel; when cleaning is completed, the rotating volute rotates to close the cleaning fixed window, so that wind resistance formed inside the shell by the cleaning mechanism is avoided, and normal operation of the indoor unit of the air conditioner is guaranteed.
It is to be understood that the invention is not limited to the examples described above, but that modifications and variations may be effected thereto by those of ordinary skill in the art in light of the foregoing description, and that all such modifications and variations are intended to be within the scope of the invention as defined by the appended claims.
