Air supply system of refrigerator and air-cooled refrigerator

Abstract

The invention discloses an air supply system of a refrigerator and an air-cooled refrigerator, relates to the technical field of refrigerators and aims at solving the problems of relatively high complexity and poor cooling effect of the existing air supply system of the refrigerator. The air supply system of the refrigerator comprises an air duct cover plate; a sealed air cavity is defined by the air duct cover plate and an inner container of the refrigerator; an evaporator of the refrigerator is arranged on the outer surface of the inner container and corresponds to the sealed air cavity in position; the sealed air cavity is internally provided with air guide ribs by which the sealed air cavity is divided into an air suction region, a first air supply region and a second air supply region which sequentially communicate; an air suction hole is formed in the air suction region; the first air supply region is located above the air suction region; an upper air outlet is formed in the air supply region; the second air supply region is located at the lower part of the first air supply region and is spaced from the air suction region by the air guide ribs; a lower air outlet is formed in the second air supply region; and air in a refrigerator chamber is sucked by the air suction hole, one part of air enters the refrigerator chamber from the upper air outlet, and the other part of air enters the refrigerator chamber from the lower air outlet. The air supply system can be used for the air-cooled refrigerator.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a refrigerator air supply system and an air-cooled refrigerator. Background technique [0002] At present, with the popularization and application of air-cooled refrigerators, they are more and more favored by consumers. The refrigeration principle of the air-cooled refrigerator is to use circulating air for refrigeration. When the high-temperature air flows through the built-in evaporator, the two directly exchange heat, and the temperature of the air will decrease. After the heat exchange, the cold air is blown into the air-cooled refrigerator. , thereby lowering the temperature of the air-cooled refrigerator. But how to improve the cooling effect of air-cooled refrigerators has become the focus of research and development of air-cooled refrigerators. [0003] An existing refrigerator air supply system, such as figure 1 and figure 2 As shown, it includes the air duct...

AI Technical Summary

Problems solved by technology

[0004] In the existing refrigerator air supply system, the air chamber 04 is surrounded by two covers, the air duct front cover 01 and the air duct rear cover 02, which makes its structure relatively complicated, which is not conducive to reducing the air supply of the refrigerator. The cost of wind system components; such as figure 1 As shown, in the existing air supply system of this refrigerator, the evaporator 08 is arranged at the bottom of the evaporator bin 07, and the fan 03 (ie, the entrance of the air chamber 04) is arranged at the top of the evaporator bin 07, and The cold air after the heat exchange in the evaporator 08 needs to move up to the top of the evaporator chamber 07, and then be sucked into the air chamber 04 by the fan 03, and then the cold air flows down in the air chamber 04, and then passes through the air outlet 011 Entering into the compartment 06 of the air-cooled refrigerator, the path between the wind and the air outlet 011 after heat exchange with the evaporator 08 is relatively long, so that the heat exchange between the cold air and the liner of the air-cooled refrigerator during the flow is easy to be lost Large cooling capacity, which is not conducive to improving the cooling effect of air-cooled refrigerators
