Description

Air conditioner Technical Field The utility model relates to the technical field of household appliances, in particular to an air conditioner. Background In the related art, when the air conditioner is in a cooling mode, water vapor in the air hits the low-temperature evaporator, condensed water is formed, and the condensed water flows into a water receiving tray of the indoor unit. In the process of condensate water generation, impurities such as flocks, dust, hair and the like in the low-temperature evaporator and the air are collected into the water receiving disc. The condensed water is discharged outdoors through a drain pipe by adopting a drain pump from the water receiving disc.
