The heat exchanger is mounted on the upper chassis, and the fan is detachably mounted on the lower chassis. In the above prior art, the fan, the blades and the water channel need to be disassembled together to clean the pollutants in the fan blade. The motor assembly needs to be removed and cleaned together with the air duct component. The following problems occur: when the cleaning is performed, the sewage is easily entered into the motor portion connected to the blade to damage the water of the motor; or, when the user cleans, forget to disconnect the fan power supply. And it may cause the user to get an electric shock.

In order to solve the above technical problem, the Chinese patent document CN202792451U discloses a wall-mounted air conditioner indoor unit casing which is easy to be removed and washed, and includes a casing and a frame which are mutually interlocked, and the frame is separated, and the casing is first unloaded during cleaning. , remove the fixing screws between the upper frame and the lower frame, then remove the lower frame, then remove the fixing screws of the fan blades and the fan motor shaft, and continue to remove the upper and lower reinforcing rings of the side support frame, which can be easily Remove the blades. However, in the prior art, the fan blade and the blade motor are disassembled, and the screw needs to be removed first, and then the reinforcing ring is removed to remove the blade connected to the blade motor, that is, the disassembly of the blade and the motor is complicated; on the other hand, the user When cleaning, it is necessary to disconnect the motor and power supply wires of the fan, and reconnecting the power cable may result in poor wiring. Among them, the light influences the use, and the other may cause damage to the motor, and even the user may get an electric shock.

However, in the prior art, the impeller is actually supported on the bottom casing and is in the open chamber which is surrounded by the heat exchanger, and only the gap left between the two is usually not opposite to the impeller. It is difficult to reach the impeller from the outside through the slit, and it is necessary to find a suitable tool to contact and dial the impeller through the slit, which is troublesome to use. On the other hand, in an uncontrollable state such as a collision or a tilt which may occur during the take-out process, the operation of closing the motor shaft sleeve back and forth easily causes damage to the motor bushing and the output shaft of the motor. After the impeller is separated from the motor, since the bottom case is still part of the base, it is still necessary to remove the heat exchanger first. The impeller can be taken out.
