Abstract

A connection structure of water drainage pipe on indoor unit of air-conditioner consists of water drainage pipe nozzle on indoor unit and water drainage connection pipe connected with said nozzle. It is featured as setting multiple ring form ledge on external surface of water drainage connection pipe in uniform interval mode, setting connection end of water drainage connection pipe with said nozzle to be circular nozzle and arranging rubber seal ring in said nozzle then setting iron fastening ring at external periphery of said nozzle, setting external peripheral surface of another end at said pipe to be reversed circular truncated cone form being connected to water drainage pipe.

Description

technical field [0001] The invention relates to a drainpipe connection structure of an air conditioner indoor unit. Background technique [0002] Generally, the air conditioner of the conventional technology includes the following devices: a compressor that compresses the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure compressor; , an outdoor heat exchanger for cooling); an expansion valve that expands the liquid refrigerant condensed in the condenser; an evaporator that evaporates the refrigerant injected from the expansion valve (an outdoor heat exchanger for heating, and an outdoor heat exchanger for cooling). indoor heat exchanger); four-way valve that switches the flow of refrigerant according to cooling or heating operation. The expansion valve is installed in the indoor unit or the outdoor unit, and the indoor unit and the outdoor unit are connected by refrigerant piping. The structure of the indoor unit is shown in Fi...
