Air conditioner indoor unit drainage nozzle sealing structure and air conditioner indoor unit

Abstract

The invention provides an air conditioner indoor unit drainage nozzle sealing structure. The air conditioner indoor unit drainage nozzle sealing structure comprises a drainage nozzle, a drainage pipe and a seal ring. The seal ring is inlaid into the assembling end of the drainage pipe. The seal ring is cylindrical in whole, at least one annular protrusion is disposed on the inner wall of the seal ring, and the drainage nozzle is assembled in the seal ring. The invention further provides an air conditioner indoor unit adopting the drainage nozzle sealing structure. By improving the structure of the seal ring, the assembling contact surface is reduced, so that the friction force is reduced, the assembling is easier, the same sealing effect is maintained, water seepage and water leakage are avoided, and accordingly, the problem of difficult air conditioner indoor unit drainage nozzle sealing assembling is solved. The sealing structure does not need any lubrication assistance, the problem of low assembling efficiency is solved, and the sealing structure can be applied to all split wall-hanging indoor units.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a sealing structure for a drain nozzle of an air conditioner indoor unit and the air conditioner indoor unit. Background technique [0002] Usually, the drain pipe and the drain nozzle of the indoor unit of the air conditioner are connected and sealed through interference fit, and a soft sealing ring is provided inside the connection end of the drain pipe. The sealing structure of the drain nozzle is as follows: the mating surface of the indoor unit drain nozzle is Conical surface, and the drainpipe sealing ring that is assembled and sealed with the drain nozzle is also a conical surface. When assembling, the sealing structure of the interference fit between the two conical surfaces is in contact with the conical surfaces. In order to ensure the sealing effect, the friction force is very large. Moreover, because the soft sealing ring in the drainpipe has a la...

AI Technical Summary

Problems solved by technology

Moreover, because the soft sealing ring in the drainpipe has a large amount of shrinkage in a low temperature environment, the interference with the drain nozzle of the air conditioner internal unit becomes larger, the friction force increases, the assembly becomes difficult, and the assembly efficiency is low; especially affecting some For foreign customers with low production environment temperature, the shrinkage of the soft sealing ring of the drain pipe is very large, so the assembly is very difficult

In order to improve the assembly efficiency, the customer added lubrication during assembly, which made assembly more troublesome and low assembly efficiency

[0003] Therefore, the technical problem faced is: the sealing ring in the drain nozzle and the drain pipe should be sealed reliably and easy to assemble
