Suction piping, suction structure, household appliances and dehumidifiers

Abstract

The invention discloses an auxiliary suction pipe, a suction structure, a household appliance and a dehumidifier for lowering noise produced by the auxiliary suction pipe and relates to the field of household appliances. The auxiliary suction pipe comprises a first suction pipe and a connecting pipe, one end of the connecting pipe is communicated with the other end of the first suction pipe, and the ratio between the outer diameter of the first suction pipe and the outer diameter of the connecting pipe is less than 63%. Different form the existing auxiliary suction pipe formed by pipes with the outer diameter more than 63% of the size of the connecting pipe, the auxiliary suction pipe applies the first suction pipe with small outer diameter, noise caused by vibration of the pipe is lowered by the aid of flexibility of the pipe, and noise of the complete appliance is lowered to the uttermost degree; meanwhile, pipe stress is released better, and stress-strain is lowered.

Description

Technical field [0001] The invention relates to the field of household appliances, in particular to a suction piping, a suction structure, a household appliance and a dehumidifier. Background technique [0002] With the improvement of the quality of life, small and compact household dehumidifiers have gradually entered people's lives, and the public has higher and higher requirements for the performance of dehumidifiers. The noise of household dehumidifiers directly affects the user's experience. The abnormal noise of household dehumidifiers is mainly caused by the combined action of compressors, fans, piping and sheet metal parts, especially the noise caused by the vibration of the piping, which greatly contributes to the vibration and noise of the whole machine, and the Large vibrations are also likely to cause fatigue fracture of piping. [0003] At present, the suction pipe design of the existing household 40L dehumidifier mostly adopts Φ6, Φ7, Φ8, and Φ9 pipeline connections...

AI Technical Summary

Problems solved by technology

[0004] The inventors found that there are at least the following problems in the prior art: the vibration source of the household dehumidifier mainly comes from the compressor of the dehumidifier, and is transmitted to the outside through the foot of the compressor and the piping pipeline. The vibration of the compressor and the influence of the refrigerant flow make it in a forced vibration state, resulting in obvious vibration and noise

Specifically, after the compressor is installed in the dehumidifier, the suction pipeline of the compressor is limited by the small space, and the layout of the pipeline is relatively difficult. The force received inside the pipeline cannot be released effectively and reasonably, so the vibration of the pipeline is aggravated, and at the same time, vibration noise is generated, resulting in relatively large vibration and noise of the dehumidifier

The existing piping method leads to large vibration stress and strain of the pipeline. Generally, the maximum strain is over 280μ during start-up and shutdown, and the maximum strain during operation is above 60μ. The overall strain is high and extremely unstable, and there is a great risk of pipeline leakage

Moreover, the noise value and sound quality of the compressor piped by this method are generally poor, which cannot meet the requirements of contemporary people for dehumidifiers.
