[0002] Since the wall-mounted indoor unit of an air conditioner is generally installed at a relatively high height, it is inconvenient to add water to the humidification module of the air conditioner as it requires climbing to a high place. To avoid climbing to add water, in the prior art, an electric drive structure is generally provided to drive the water tank to lift and lower, so that the water tank can be lowered when adding water and lifted after adding water. One type of electric drive structure for driving the water tank to lift and lower is to use a motor to drive a wire wheel to retract and release a pull rope to achieve the lifting and lowering of the water tank, and the other is to use a motor to drive a foldable and telescopic structure (such as a scissors frame) to drive the water tank to lift and lower.

[0003] No matter which of the above two methods is adopted, it requires a motor and an actuator to achieve, and the motor and the actuator are bound to occupy a relatively large space, which will cause an increase in the volume of the wall-mounted indoor unit of the air conditioner, a reduction in the volume of the water tank, and an increase in cost. Therefore, how to better realize convenient water addition to the water tank installed in the wall-mounted indoor unit of the air conditioner has become an urgent technical problem in this field.
