Air treatment device

Abstract

The invention relates to an air treatment device. A humidifying rotating wheel can be prevented from being blocked on a fixed shaft, and a driving component and a driven component which serve as transmission assemblies are prevented from being matched too tightly or too loosely, so that the failure rate of the air treatment device is reduced. The air treatment device comprises a drive assembly, ahumidifying rotating wheel assembly and a supporting body, wherein the driving component in the drive assembly drives the driven component in the humidifying rotating wheel assembly to rotate, the supporting body is provided with the fixed shaft, the driven component is supported by the fixed shaft in a backlash manner, and an elastic component is arranged between the supporting body and the driveassembly; the elastic component can be deformed under the force generated by the movement of the driven component, so that force is exerted to the driving component to keep the driving component matched with the driven component.

Description

technical field [0001] The invention relates to an air treatment device. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for their own office and living environment. For example, there is increasing demand not only for household appliances such as refrigeration or heating air conditioners that regulate the ambient temperature, but also for air handling devices such as humidifiers or dryers that regulate the ambient humidity. [0003] There is an air treatment device in the prior art, which uses, for example, zeolite as a material to make a dehumidification wheel, and utilizes the hygroscopic characteristics of the dehumidification wheel to realize the function of adjusting air humidity without using a compressor (for example, refer to the following Patent Document 1). [0004] Patent Document 1: CN202096871U [0005] Specifically, in the air treatment device of the above-mentioned prior art, the characteri...

Problems solved by technology

[0006] However, in the air handling device of the above-mentioned prior art, there is the following problem: since the gear set as the transmission member is usually molded from materials such as resin with a high thermal expansion coefficient, the driving gear of the gear set may be separated from the Poor engagement between driven gears

Coupled with the changing temperature conditions in the air handling unit, the engagement between the driving gear and the driven gear may even be too tight due to thermal expansion and contraction (the driving gear and the driven gear are too close) or too loose ( The driving gear is too far apart from the driven gear, or even completely separated) to cause instability and discontinuity of the transmission (for example, in this case, when viewed along the direction of the rotation axis of the driving wheel and / or driven wheel, drive and / or driven wheels are non-perfectly circular) and thus unable to drive the zeolite member in rotation

In addition, the humidity control rotor itself will also expand with heat and contract with cold. When the humidity control rotor and the fixed shaft cooperate without play, it will cause the humidity control rotor to be stuck on the fixed shaft and cannot rotate, which will eventually lead to air treatment. device failure
