Problems solved by technology

However, sticking sound-absorbing cotton on the inside of the air duct increases the material cost, reduces the fluid space in the air duct, and changes the flow field while causing secondary noise
In addition, the sound-absorbing cotton is easy to absorb condensed water, and in severe cases, ice blockage will occur, hindering air circulation, and the operation reliability is low

Abstract

The invention discloses a refrigerator and an air duct plate of the refrigerator. The refrigerator comprises a refrigerator body which is internally provided with refrigerating chambers, door bodies installed on the refrigerator body and used for opening or closing the refrigerating chambers and an air duct arranged in the refrigerator body, wherein the air duct comprises the air duct plate, and silencing blind holes spaced to one another are formed in the inner wall face of the air duct plate. According to the refrigerator, due to the fact that the silencing blind holes are formed in the inner wall face of the air duct plate, noise can form resonance at peak frequency bands, so that the silencing coefficient and the sound resistance of the air duct plate are improved, and the sound absorption bandwidth is enlarged. In addition, the silencing blind holes formed in the inner wall face of the air duct plate are used for replacing silencing cotton to reduce fluid noise generated when air flow flows through the air duct plate, secondary noise brought by the silencing cotton is lowered, the problem that the air duct is blocked by ice due to water absorption of sound absorption cotton is effectively solved, the production cost is reduced, and the long-term operation reliability of the product is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator and a panel of the refrigerator. Background technique [0002] The fluid noise of the ventilation system is one of the noise sources of the air-cooled refrigerator. In the related art, sound-absorbing cotton is pasted on the inner wall of the air duct (for example, the inner wall of the air duct plate) to reduce the noise. However, sticking sound-absorbing cotton on the inside of the air duct increases the material cost, reduces the fluid space in the air duct, and changes the flow field while causing secondary noise. In addition, sound-absorbing cotton is easy to absorb condensed water, and in severe cases, ice blockage occurs, hindering air circulation, and operating reliability is low. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, t...
