When the air amount needs to be increased, the variable air outlet 1c is switched to be communicated with the air inlet air duct 112, and when the air supply area needs to be improved, the variable air outlet 1c is switched to be communicated with the air outlet air duct 111. On the limited area of the shell 1, the variable air outlet 1c can play the air inlet and air outlet roles, so that the air inlet and air outlet effects of the air conditioner 100 can be enriched without increasing the area of the shell 1.

[0048] According to the air conditioner 100 of the embodiment of the present application, by opening the variable air outlet 1c on the shell 1 and switching the variable air outlet 1c to be communicated with the air outlet air duct 111 and the air inlet air duct 112 by the switching component 3, the variable air outlet 1c can be switched according to the actual use condition, and the functionality of the air conditioner 100 is improved, so that the air inlet and air outlet effects of the air conditioner 100 can be enriched without increasing the area of the shell 1.

Only one switch door 31 is needed to control the opening and closing of the first bypass port 51 and the second bypass port 61. Compared with setting two switch doors 31 to control the opening and closing of the first bypass port 51 and the second bypass port 61 respectively, the structure of the switching component 3 can be simplified and the control can be simplified.

[0072] like Figure 1 As shown, when the door 31 is in the first position, the door 31 opens the first bypass port 51 and closes the second bypass port 61.
