Problems solved by technology

[0004] (1) The air inlet and outlet direction of the axial flow fan is straight in and out along the axial direction, so the impact of the air flow on the air duct cover plate is very strong, resulting in high aerodynamic noise, and strong impact loss will also cause energy loss. The flow is reduced, which is not good for the energy consumption of the whole machine
[0005] (2) In order to meet the air volume requirements, the overall height of the axial flow fan is generally high, which will increase the space occupied by the air supply system, correspondingly reduce the volume of the inner tank, or reduce the thickness of the foam layer, which is harmful to the refrigerator. The performance and volume of the whole machine are adversely affected

Embodiment Construction

[0057] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0058] In order to fundamentally improve the air circulation mode, the present invention adopts a centrifugal fan and cooperates with a reasonable air duct to replace the previous axial flow fan structure, which makes the air circulation in the refrigerator more reasonable, effectively reduces the energy loss of the flow channel, and reduces the aerodynamic noise.

[0059] refer to Figure 1-3 As shown, an air supply system for a large-volume air-cooled refrigerator includes an air duct and a centrifugal fan 1. The centrifugal fan 1 adopts a centrifugal fan with two-way air outlets, and adopts a compact outer rotor structure, including a motor 11 and an impeller 12. And the volute 13, the air duct is a double volute tongue arc-shaped centrifugal air duct separated up and down, and the volute 13 is composed of the above-mentioned doubl...

Abstract

The invention provides an air supply system for a large-volume air cooled refrigerator and the air-cooled refrigerator. The air supply system comprises an air channel and a draught fan, wherein a centrifugal draught fan with bidirectional air outlets is adopted by the draught fan. The invention further provides the air-cooled refrigerator adopting the air supply system. According to the air supply system for the large-volume air-cooled refrigerator and the air-cooled refrigerator, the novel centrifugal draught fan is adopted for being matched with reasonable air channel design, good flow tracks are obtained, structural vibration and pneumatic noise of the air supply system are reduced, the space occupied by the air supply system is reduced, the volume of the inner container of the refrigerator is increased, cost is reduced, energy consumption is lowered, energy is saved, and emission is reduced.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to an air supply system for a large-capacity air-cooled refrigerator and an air-cooled refrigerator using the air-cooled system. Background technique [0002] With the increasing popularity of refrigerators, users have higher and higher requirements on refrigerator energy consumption and noise. Aerodynamic noise. [0003] At present, the air supply system of an air-cooled refrigerator mainly adopts an air supply system with an axial flow fan as a power source. Since the air flow of the axial flow fan enters and exits along the axial direction of the fan, and there must be an air duct cover plate in the axial direction of the fan, the air supply system of the axial flow fan mainly has the following disadvantages: [0004] (1) The air inlet and outlet direction of the axial flow fan is straight in and out along the axial direction, so the impact of the air flow on ...
