Problems solved by technology

[0002] Air duct system noise is one of the main noise sources of air-cooled refrigerators. Unreasonable air duct design will lead to excessive aerodynamic noise. Existing air ducts mainly consider the distribution of air flow when designing air outlets, but do not consider the relative position of the air outlets. The impact of noise, because the fan blade is a rotating part, its peripheral speed is high, and the air flow is disturbed greatly, which is the main source of fluid noise
In the related technology, the air outlets are concentrated at the noise source, which can promote the noise diffusion, and the interference between the air outlets and the blade tips of the fan blades produces secondary noise, resulting in excessive noise in the refrigerator as a whole

Abstract

The invention discloses a refrigerator which comprises a cabinet, a door body, an air passage and a fan, wherein a refrigeration compartment is arranged in the cabinet; the door body is arranged on the cabinet and used for opening or closing the refrigeration compartment; the air passage is arranged in the cabinet; the air passage comprises an air passage plate, a plurality groups of air holes which are mutually spaced are formed in the side wall of the air passage plate; the air holes are communicated with the refrigeration compartment; the fan is arranged in the air passage; the center axis of the fan is vertical to the air passage plate; the air holes of the air passage plate are formed far away the fan. According to the refrigerator disclosed by the invention, the air holes are formed at a position far away from the refrigerator, namely the air holes are formed at a position far away from a noise source, so that noise transmission is effectively controlled; the interference between the air holes and the fan is reduced, consequently secondary noises are reduced, the fluid noise in the refrigerator is reduced, and the quality of the refrigerator is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a refrigerator. Background technique [0002] Air duct system noise is one of the main noise sources of air-cooled refrigerators. Unreasonable air duct design will lead to excessive aerodynamic noise. Existing air ducts mainly consider the distribution of air flow when designing air outlets, but do not consider the relative position of the air outlets. The impact of noise, because the fan blade is a rotating part, its peripheral speed is high, and the air flow is disturbed greatly, which is the main source of fluid noise. In the related art, the air outlets are concentratedly arranged at the noise source, thereby promoting noise diffusion, and the interference between the air outlets and the tips of the fan blades produces secondary noise, resulting in excessive noise of the refrigerator as a whole. Contents of the invention [0003] The present invention aims to ...
