Problems solved by technology

[0003] In order to overcome the above problems, it is generally used to paste sound-absorbing cotton on the smooth inner wall of the air duct of the air-cooled refrigerator (for example, the inner wall of the air duct plate) to reduce noise. Only sound-absorbing cotton is used. Due to material limitations, the sound-absorbing frequency band and noise reduction 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.
[0004] Further, in the prior art, a sound-absorbing plate with sound-absorbing holes has also been developed on the inner wall of the air duct (for example, the inner wall of the air-channel plate), and the sound-absorbing plate with the sound-absorbing holes can indeed reduce the airflow flowing through the air duct. noise, however, also blocks the flow of airflow

Abstract

The invention provides an air duct applicable to an air feeding system of a refrigerator. The air duct comprises an airflow channel, at least one side plate and a plurality of partition plates, wherein the at least one side plate is arranged around the airflow channel; the plurality of partition plates are arranged in the airflow channel, and a silencing cavity is formed between any two adjacent partition plates in the plurality of partition plates; and the silencing cavities are used for eliminating or lowering airflow noise of airflow flowing through the airflow channel.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air duct and a refrigerator thereof. Background technique [0002] Existing air-cooled refrigerators use fans to force air for cooling. Compared with direct-cooled refrigerators, the airflow noise generated by the fan flowing through the ventilation system becomes one of the noise sources of air-cooled refrigerators. [0003] In order to overcome the above problems, it is generally used to paste sound-absorbing cotton on the smooth inner wall of the air duct of the air-cooled refrigerator (for example, the inner wall of the air duct plate) to reduce noise. Only sound-absorbing cotton is used. Due to material limitations, the sound-absorbing frequency band And noise reduction is 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...
