Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a glass-door air-cooled refrigerator with an automatic air guiding device. Background technique [0002] At present, most of the freezers on the market adopt the direct cooling refrigeration method, that is, the evaporator is attached to the inner wall of the tank, and the compressor provides power to drive the refrigerant to circulate in the refrigeration system, and the cooling energy is directly transmitted to the inside of the cabinet. The pipeline of this structure is complicated, the installation is difficult, and the inner wall of the box is prone to frost during use, which affects the storage effect of the goods. Moreover, in the existing technology, the cross-sectional area of ​​the traditional air duct is the same everywhere in the length direction. When the air supply volume of the fan is constant, the air volume will be consumed through the air outlet ...

AI Technical Summary

Problems solved by technology

The pipeline of this structure is complex and difficult to install. During use, the inner wall of the box is prone to frost, which affects the storage effect of the goods.

Moreover, in the existing technology, the cross-sectional area of ​​the traditional air duct is the same everywhere in the length direction. When the air supply volume of the fan is constant, the air volume will be consumed through the air outlet at the front position during the air supply process, resulting in a decrease in the wind speed in the subsequent path. , the wind speed at the air outlet at the end position away from the fan is the lowest, which will inevitably lead to inconsistent air supply at each position and uneven cooling

[0003] In view of the above problems, the Chinese invention patent with the publication number 20210476284.8 proposes a glass-door air-cooled refrigerator and its control method. The patent provides an air outlet structure that solves condensation. The fixed angle guides the cold air to the bottom of the box, and the second air supply sub-board is equipped with a windshield to adjust the air volume. This structure is designed to concentrate the air volume at the bottom of the box, and the indoor cooling is not uniform

[0004] The Chinese invention patent with publication number 202110476188.7 proposes a horizontal air-cooled freezer. The patent provides an air supply duct structure, which has air outlets of different sizes and shapes at different positions on the inner wall to adjust the air output of each area. The size and the number of air outlets on the inner wall are too large, which is greatly affected by the air flow of the air supply duct, and the cooling effect is lacking

[0005] The Chinese invention patent with the publication number 20210474569.1 proposes a horizontal refrigerator and its working method. The patent provides a device for uniform distribution of cold air, which adjusts the position of the air outlet assembly by detecting the quality of the goods to achieve uniform cooling. But its structure is complicated, the manufacturing cost is high, and the air conditioning effect is not obvious
