Air duct cover plate and air cooling refrigerator

Abstract

The invention provides an air duct cover plate and an air cooling refrigerator. The air duct cover plate comprises a plate body and a sliding insertion plate. A plurality of first air outlets are formed in the plate body. A slide way is arranged on the plate body. The sliding insertion plate is arranged in the slide way and can slide in the slide way relative to the plate body so that the air outlet area of each first air outlet can be changed. According to the air duct cover plate, the sliding insertion plate is arranged on the plate body, the air outlet area of each first air outlet is changed by adjusting the sliding insertion plate, and therefore the air outlet volume, namely, the refrigeration effect, of the air cooling refrigerator is changed, the use comfort degree of the product is increased, and market competitiveness of the product is improved; meanwhile, in a related performance test, the sizes of the first air outlets can be freely adjusted according to the test condition, and therefore the related performance test cycle is shortened, no air duct cover plate with the first air outlets in different sizes needs to be manufactured, experiment efficiency is improved, and development cost is reduced.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to an air duct cover plate and an air-cooled refrigerator including the air duct cover plate. Background technique [0002] At present, the cold energy emitted by the surface of the evaporator of the air-cooled refrigerator is distributed to the entire space of the freezer along the corresponding air outlet of the air duct cover plate to achieve the purpose of cooling; the size of the air outlet on the air duct cover plate is Fixed, that is, the size of these air outlets has been set during product design, so the cooling capacity flowing out of the air outlets is also certain. This kind of setting of the air duct cover includes the following defects: [0003] 1. During the development process, we need to determine the size of the air outlet according to the performance test. During the test process, manual modification (by cutting or patching) is required to finally determine ...

Problems solved by technology

[0003] 1. During the development process, we need to determine the size of the air outlet according to the performance test. During the test process, manual modification (by cutting or patching) is required to finally determine the size of the opening. For different customers and different regions There may be differences, and the performance requirements of the product are also different. It is often necessary to adjust the relevant air outlets. Generally, the area of ​​​​the air outlets is adjusted to obtain the required air volume. This is the only way to modify the mold, which is expensive and expensive. Long cycle and low efficiency;

[0004] 2. During the use of the refrigerator, the cooling capacity of the refrigerator cannot be adjusted according to the needs
