Problems solved by technology

At present, in order to increase the cooling speed, in most cases, the fan is equipped with a high-speed gear, and the speed can reach more than 2000rpm. At this time, the fluid flow speed at the air outlet is accelerated, and the noise is obviously increased.

Abstract

The invention provides an air duct assembly and a refrigerator with the air duct assembly. The air duct assembly comprises an air duct body, an air duct cover plate, a fan and an air outlet baffle, wherein the air duct cover plate and the air duct body are connected to define an air duct, an air outlet is formed in the air duct cover plate, the fan is arranged in the air duct, the air outlet baffle is connected with the air duct cover plate and can rotate between a first position where the air outlet is opened and a second position where the air outlet is closed, and the opening degree of the air outlet is in positive correlation with the rotating speed of the fan. According to the air duct assembly, the opening degree of the air outlet is in positive correlation with the rotating speed of the fan, when the fan operates at a low speed, the opening degree of the air outlet baffle is small on the premise of meeting the air supply requirement, and when the fan operates at a high speed, the opening degree of the air outlet baffle is large so as to enlarge the flow area of the air outlet and reduce the flow speed at the air outlet, and therefore noise under high rotating speed of the fan is lowered.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to an air duct assembly and a refrigerator with the air duct assembly. Background technique [0002] Fan noise is one of the main noise sources of air-cooled refrigerators, and the noise at the outlet of the air duct is usually the loudest point of the fan noise. One of the main factors affecting the noise level at the air outlet is the flow velocity of the fluid at the air outlet. Generally, the higher the flow velocity, the greater the noise. [0003] With the existing air duct structure, the size and shape of the air outlet is fixed (generally designed according to the air volume of the fan at low and medium speeds, because the fan runs for a long time at low and medium speeds), and the flow velocity at the air outlet is low at low fan speeds, and the noise is small. At present, in order to increase the cooling speed, in most cases, the fan is equipped with a high-s...
