Embodiment Construction

[0058] figure 1 is a schematic side cross-sectional view of a compartment with an air supply system according to an embodiment of the present invention. figure 2 is a schematic front view of an air supply assembly according to an embodiment of the present invention. image 3 is along figure 2 A schematic cross-sectional view taken along line A-A in .

[0059]A refrigerator generally has a box body including at least one compartment and an air supply system for providing cooling capacity to the compartment. Specifically, a refrigerator may generally have a box shell as its outer surface and an inner container inside the box shell. The liner can define a compartment, and at least part of the space in the compartment can be a storage space. There can be multiple compartments, and can be set as refrigerator compartments, freezer compartments or temperature-changing compartments as required. Further, in some air-cooled or dual-system refrigerators, an air supply system with ...

Abstract

The invention provides a refrigerator. The refrigerator is provided with a refrigerator body in which at least one chamber is arranged, and an air feeding system. The air feeding system comprises an air duct cover plate, a centrifugal wind wheel and an evaporator, wherein an air feeding space is defined by the air duct cover plate and an inner container of the refrigerator chamber, and the air duct cover plate is configured to separating the air feeding space from a storage space in the chamber; the centrifugal wind wheel is arranged in the air feeding space so as to axially suck in air and blow out the air upwards; the evaporator is arranged above the centrifugal wind wheel; the air duct cover plate is provided with a plurality of return air inlets so that air in the storage space can beallowed to enter the air feeding space; the centrifugal wind wheel is attached to and arranged on the inner side of the air duct cover plate and configured to suck air from the rear side so that air fed into the air feeding space through the return air inlets can be sucked in from the rear side of the centrifugal wind wheel; and the evaporator is provided with a plurality of fins, one bottom corner of each fin is arranged into an oblique folding part so that the dropping positions of water drops on the fins can be changed. According to the refrigerator, an air suction opening of the centrifugal fan faces towards the rear side, so that the distance between the centrifugal fan and the air duct cover plate is decreased, and the volume of the storage space is increased.

Description

technical field [0001] The invention relates to the technical field of refrigeration and freezing, in particular to a refrigerator. Background technique [0002] The rear side of the freezer compartment of existing dual-system refrigerators is generally provided with an air duct for providing cooling capacity to the freezer room. The fan and air duct structure inside will occupy a certain volume of the freezer room, which is not conducive to the effective use of the compartment space. Contents of the invention [0003] An object of the present invention is to provide a refrigerator with a larger storage space. [0004] A further object of the present invention is to enhance the turbulence of the evaporator of the refrigerator to the air flowing through it, and improve the heat exchange efficiency of the evaporator. [0005] Another further object of the present invention is to simplify the assembly process of the refrigerator. [0006] In particular, the present inventio...
