Thus, the circulation of the airflow between the casing 10 and the indoor environment where the air conditioner 1 is located can be facilitated.

Specifically, both the first heat exchanger 30 and the second heat exchanger 40 are located in the air duct a. That is to say, the first heat exchanger 30 is installed in the air duct a, and the second heat exchanger 40 is installed in the air duct a, so as to facilitate the airflow in the air duct a to exchange heat with the first heat exchanger 30 and the second heat exchanger. 40 for heat exchange.

Wherein, one of the first heat exchanger 30 and the second heat exchanger 40 is an evaporator, and the other of the first heat exchanger 30 and the second heat exchanger 40 is a condenser, that is to say, the first The heat exchanger 30 can be an evaporator, then the second heat exchanger 40 can be a condenser, the first heat exchanger 30 can be a condenser, then the second heat exchanger 40 can be an evaporator.

Specifically, the air conditioner 1 can be a cooling-only air conditioner 1, or a heating and cooling air conditioner 1; when the air conditioner 1 is a cooling-only air conditioner 1, the first heat exchanger 30 is an evaporator, and the second The heat exchanger 40 is a condenser; when the air conditioner 1 is a heating and cooling air conditioner 1, in the cooling mode and the dehumidification mode, the first heat exchanger 30 is an evaporator, and the second heat exchanger 40 is a condenser. mode, the first heat exchanger 30 is a condenser, and the second heat exchanger 40 is an evaporator.

Therefore, by arranging the evaporator, condenser and wind wheel 20 in the air duct a, that is, the evaporator and the condenser share the air duct a and the wind wheel 20, the structure is simpler and more compact, which is conducive to improving production efficiency and reducing costs. The structure of the air conditioner 1 can be simplified.

The switch member 50 is movably arranged on the casing 10 to open or close the first air outlet e. For example, when the air conditioner 1 is a cooling-only air conditioner 1, when the air conditioner 1 is in the cooling mode, the switch member 50 opens the first air outlet e, and when the air conditioner 1 is in the dehumidification mode, the switch member 50 closes the first outlet e.

The heat-exchanged air flow is discharged from the second air outlet f, thus, in the cooling mode, the first heat exchanger 30 corresponds to the first air outlet e, and the air flow after heat exchange with the first heat exchanger 30 flows from the first The air outlet e flows out, the second heat exchanger 40 corresponds to the second air outlet f, and the airflow after heat exchange with the second heat exchanger 40 is discharged from the second air outlet f.
