Indoor machine of air conditioner

Abstract

The invention discloses an indoor machine of an air conditioner, which comprises a chassis, a shell, a suction grille, an indoor heat exchanger, a filter, a condense water disc, a fan motor, an indoor fan and an air guide plate. The indoor machine of the air conditioner also comprises a fixing device which fixes the indoor fan inside the chassis before the indoor machine goes out of a factory. The indoor machine of the air conditioner utilizes a fixed plug arranged at one end of the indoor fan and a plurality of fixed rings positioned on the outer circumference to firmly fix the indoor fan inside the shell before the indoor machine goes out of the factory. The fixed rings and the fixed plug are made from EPE materials with good buffer performance, thus the indoor fan cannot move in the shell even if the indoor machine is subject to external impact in the transport process, the undergone impact force can be absorbed by the fixed rings and the fixed plug, and no damage problem caused by mutual collision of the indoor fan and the indoor heat exchanger is generated, thereby improving the quality of the product.

Description

technical field [0001] The invention relates to an air conditioner, in particular to an indoor unit of the air conditioner. Background technique [0002] Generally, an air conditioner is a device that makes a refrigerant inside undergo a refrigeration or heating cycle consisting of a compression process, a condensation process, an expansion process, and an evaporation process. When the air conditioner is in the refrigeration cycle, the refrigerant compressed by the compressor and turned into a high-temperature and high-pressure state first flows into the outdoor heat exchanger, where the refrigerant will dissipate heat to the outside, then flow to the expansion valve, and then flow through the expansion valve. The valve significantly reduces its temperature and pressure, and then this low-temperature, low-pressure refrigerant will flow into the indoor heat exchanger. In the indoor heat exchanger, the refrigerant will absorb the heat of the surrounding air, and finally flow ...

AI Technical Summary

Problems solved by technology

But, there is following problem in this air conditioner indoor unit of prior art: this air conditioner indoor unit usually does not install fan motor 12 earlier before dispatching from the factory, but just wraps indoor fan 10 with film-like packing material, then puts In the inside of the chassis 1, other components such as the indoor heat exchanger 9 are installed at last

Since the indoor fan 10 is not fixed during transportation, and the cushioning capacity of the film-like packaging material is relatively poor, it is easy to collide with the indoor heat exchanger 9 due to position movement when receiving an external impact, resulting in the indoor fan being damaged. 10 damage or scratches on the indoor heat exchanger 9, this will undoubtedly affect the quality of the product
