Drainage assembly of indoor unit of air conditioner, indoor unit of air conditioner and air conditioner

Abstract

The invention relates to a drainage assembly of an indoor unit of an air conditioner. The drainage assembly comprises a drainage assembly and a blowing structure, wherein the drainage chamber comprises a water outlet; the blowing structure can generate an air flow; the air flow can push a liquid and / or a solid in the drainage channel to move to the water outlet and / or to move out of the drainage channel through the water outlet. By arranging the blowing structure to provide auxiliary power to movement of the liquid (for example, condensate water) and / or the solid (for example, foreign matterssuch as dust and impurities) in the drainage channel, the flowing speed of water in the drainage channel can be accelerated, the drainage speed of the drainage channel is accelerated and accumulated water is prevented from being generated in the drainage channel; moreover, solid foreign matters in the drainage channel are promoted to be discharged to solve the problems that the water flow is unsmooth and a lot of condensate water is accumulated in the drainage channel as the foreign matters are prevented from blocking the water outlet of the drainage channel, so that the hidden danger of waterleakage of the indoor unit of the air conditioner is eliminated.

Description

technical field [0001] The invention relates to the technical field of air conditioner drainage, in particular to an air conditioner inner unit drainage assembly, an air conditioner indoor unit and an air conditioner. Background technique [0002] When the heat exchanger of the air conditioner indoor unit is used as an evaporator, it is necessary to discharge the condensed water formed on the surface of the evaporator out of the air conditioner indoor unit. The drainage structure in the existing air-conditioning indoor unit often has the problems of unsmooth drainage, slow drainage speed or water leakage. During disassembly and inspection, it was found that this kind of drainage problem is mostly caused by the drain nozzle of the indoor unit of the air conditioner being partially or completely blocked by foreign objects. The water that cannot be drained smoothly accumulates in the drainage pipe of the indoor unit of the air conditioner, and it is easy to overflow and cause ...

AI Technical Summary

Problems solved by technology

During disassembly and inspection, it was found that this type of drainage problem is mostly caused by the drainage nozzle of the indoor unit of the air conditioner being partially or completely blocked by foreign objects.

The water that cannot be drained smoothly accumulates in the drainage pipe of the indoor unit of the air conditioner, which is easy to overflow and cause water leakage of the indoor unit of the air conditioner

In addition, when the ambient humidity is high and the heat exchanger of the indoor unit of the air conditioner produces a large amount of water, if the drainage speed of the indoor unit of the air conditioner is slow, it is easy to cause the accumulated water in the unit to overflow and the indoor unit of the air conditioner to leak.
