Problems solved by technology

[0014] During the heating operation of the air conditioner in winter, when the defrosting operation is performed to defrost the outdoor heat exchanger, the defrosting water generated after defrosting flows along the drainage channel on the chassis and passes through the drain channel set on the bottom surface of the channel. The drain hole flows out, but because the outside temperature is too low, the defrosting water starts to freeze, so it is easy to block the drain hole with ice

Description

technical field [0001] The present invention relates to an outdoor unit for an air conditioner, and in particular to a device for preventing freezing of a drainage structure of the outdoor unit for an air conditioner. Background technique [0002] In general, air conditioners are roughly classified into a package type air conditioner in which an indoor unit and an outdoor unit are provided in one cabinet, and an outdoor unit in which a compressor and a condenser are provided in a cabinet outdoors, depending on how the units are composed. , The evaporator is set indoors as a split-type air conditioner for the indoor unit. [0003] Recently, since the market has higher and higher requirements for the cooling capacity of split-type air conditioners, in large-scale air conditioners, several compressors are equipped on the outdoor unit to effectively meet various cooling requirements. [0004] Below, the outdoor unit in the air conditioner designed in the prior art is illustrate...
