Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning outdoor units, in particular to a self-cleaning air-conditioning outdoor unit. Background Art

[0002] The function of the air conditioner outdoor unit is to cool down and dissipate the high-pressure and high-temperature gas discharged from the indoor unit outdoors (through a fan). The condensed refrigerant liquid is then sent to the evaporator of the indoor unit through a capillary tube to evaporate into gas to absorb indoor heat. This cycle is repeated and the indoor temperature will gradually drop.

[0003] Although the existing technology has the characteristics of precise control and electricity saving, the traditional air-conditioning outdoor unit does not have the self-cleaning function. Since the air-conditioning outdoor unit must be installed outdoors for heat exchange operations, it is easily affected by the external environment. The air-conditioning outdoor unit is placed outdoors for a long time, and dust is easily accumulated on its surface. People do not clean it frequently, which can easily reduce its service life and easily affect the heat exchange function of the air-conditioning outdoor unit.

[0004] Therefore, those skilled in the art provide a self-cleaning air conditioner outdoor unit to solve the problems raised in the above background technology. Utility Model Content
