Air-cooled refrigerator air cavity structure and air-cooled refrigerator

Abstract

The invention discloses a wind cavity structure of an air-cooled refrigerator and the air-cooled refrigerator, and relates to the technical field of refrigerators. The wind cavity structure of the air-cooled refrigerator and the air-cooled refrigerator are invented to uniformize outlet wind entering every position of a storage cabinet of the refrigerator and improve the refrigerating effect of the refrigerator. The wind cavity structure of the air-cooled refrigerator comprises a shell; a wind passage formed in the shell, a centrifugal blower is arranged in the wind passage, and a left wind distributing bulge and a right wind distributing bulge are formed at the positions, close to the centrifugal blower, of the left side wall and the right side wall of the wind passage correspondingly; and the centrifugal blower rotates clockwise, the left wind distributing bulge is higher than the lower edge of the centrifugal blower, and the right wind distributing bulge is lower than the lower edge of the centrifugal blower, alternatively, the centrifugal blower rotates counterclockwise, the left wind distributing bulge is lower than the lower edge of the centrifugal blower, and the right wind distributing bulge is higher than lower edge of the centrifugal blower. The wind cavity structure of the air-cooled refrigerator is used for wind supplying in the air-cooled refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an air chamber structure of an air-cooled refrigerator and an air-cooled refrigerator. Background technique [0002] According to the cooling method, refrigerators are generally divided into direct-cooling refrigerators and air-cooling refrigerators. Compared with direct-cooling refrigerators, air-cooling refrigerators can achieve frost-free, avoid manual defrosting, and have relatively low energy consumption, so they are favored by people. The cooling of the air-cooled refrigerator is to install an evaporator inside the inner tank, and then send the cold air to various positions of the refrigerator through a fan and an air duct to realize cooling in the refrigerator. Therefore, the air duct structure in the air-cooled refrigerator is an extremely important part. [0003] The prior art provides an air cavity structure of an air-cooled refrigerator, such as figure 1 As sho...

AI Technical Summary

Problems solved by technology

[0004] However, the following problems exist in the prior art: since fan 03 is a centrifugal fan blade, according to the principle of centrifugal fan blade air supply, the wind direction of its outlet is all along the circumferential tangent direction of the fan blade, corresponding to a single upper air duct or lower air duct Generally speaking, the air distribution volume on the left and right sides is uneven, that is, the air distribution volume in the two areas on either side is not symmetrical in terms of speed or air volume, and then enters the storage area through the upper air duct or the lower air duct. The volume of cold air inside the room is different, which makes the temperature in each position of the storage room uneven, which affects the cooling effect of the refrigerator
