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

Embodiment Construction

[0026] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027] Refer to the attached figure 1 The air channel plate 150 for the refrigerator 100 according to the embodiment of the present invention will be described in detail. The air channel plate 150 may be disposed in the refrigerator 100 to form the air channel 130 in the refrigerator 100 . The evaporator 140 of the refrigerator 100 is disposed adjacent to the air inlet 131 of the air duct 130 , and a fan assembly 200 is provided between the evaporator 140 and the air inlet 131 of the air duct 130 to blow cool air around the evaporator 140 into the air duct 130 .

[0028] like figure 1 As shown, the air channel plate 150 used in the refrigerator 100 according t...

Abstract

The invention discloses a refrigerator and an air duct plate thereof. Among them, the refrigerator includes: a box body with a refrigeration compartment; a door body installed on the box body for opening or closing the refrigeration compartment; an air duct arranged in the box body, and the air duct includes The inner wall of the air duct plate is provided with sound-absorbing blind holes spaced apart from each other. According to the refrigerator of the present invention, by setting the sound-absorbing blind hole on the inner avoiding surface of the air channel plate, the noise can be resonated in the peak frequency band, thereby improving the silencing coefficient and acoustic impedance of the air channel plate, and increasing the sound absorption bandwidth. In addition, the sound-absorbing blind hole is used to replace the sound-absorbing cotton on the inner avoiding surface of the air channel plate to reduce the fluid noise generated when the air flow passes through the air channel plate, reducing the secondary noise caused by the sound-absorbing cotton, and effectively solving the problem. The ice blockage of the air duct caused by the water absorption of the sound-absorbing cotton reduces the production cost and improves the long-term operation reliability of the product.

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...
