Refrigerator and wind way plate thereof

Abstract

The invention relates to the technical field of household appliances, and discloses a refrigerator and a wind way plate thereof. The wind way plate comprises an outer side plate, an inner side plate and a surrounding plate, wherein the outer side plate and the inner side plate are oppositely arranged; the surrounding plate is respectively connected with the outer side plate and the inner side plate to define a sound absorption cavity; and the inner side plate is provided with multiple sound absorption holes communicated with the sound absorption cavity at intervals. The wind way plate comprises the inner side plate, the outer side plate and the surrounding plate to define the sound absorption cavity; the sound absorption holes are formed in the inner side plate, and are all communicated with the sound absorption cavity; and as the sound absorption holes are correspondingly communicated with the sound absorption cavity to form multiple Helmholtz resonators connected in parallel to form an excellent sound absorption system, compared with the prior art, the wind way plate can effectively improve the sound absorption effect, reduce the refrigerator wind way noise and promote the refrigerator silence quality.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator and an air channel plate thereof. Background technique [0002] The fluid noise of the ventilation system is one of the noise sources of air-cooled refrigerators. In the prior 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 noise, and only sound-absorbing cotton is used. However, due to the limitation of materials, the sound absorption frequency band and noise reduction strength are limited, and the sound absorption effect is poor, which cannot satisfy people's pursuit of silent refrigerators. Moreover, 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.

[0002] The fluid noise of the ventilation system is one of the noise sources of air-cooled refrigerators. In the prior 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 noise, and only sound-absorbing cotton is used. , due to the limitation of materials, the sound absorption frequency band and noise reduction strength are limited, and the sound absorption effect is poor, which cannot meet people's pursuit of silent refrigerators

Moreover, 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.
