air cooled refrigerator

Abstract

The invention provides an air-cooled refrigerator, which includes: an air supply distributor, a compression refrigeration system, and a controller. The air supply distributor is used to distribute cold air to the air passages leading to each storage area of ​​the air-cooled refrigerator, and it includes: a housing with a plurality of air outlets respectively communicating with a plurality of air passages; an adjustment member with one or more The shielding part is configured to rotate in a controlled manner, so as to adjust the shielding part to shield the air outlet area of ​​multiple air outlets, thereby changing the air supply area to multiple air ducts; a magnetic part, arranged on the adjustment part; a magnetic induction part , fixed on the outer periphery of the casing, configured to be triggered by a magnetic component to output an indication signal of running in place. The controller, and after determining that the regulator is operating abnormally, closes the compression refrigeration system and turns on the defrosting heating wire, so that the air-cooled refrigerator enters the defrosting state, and removes the frost that freezes the air supply distributor. Therefore, the refrigeration failure caused by the freezing of the air supply distributor can be found in time and dealt with, thereby improving the operation reliability of the air-cooled refrigerator.

Description

technical field [0001] The invention relates to the field of refrigerated and frozen storage, in particular to an air-cooled refrigerator. Background technique [0002] For air-cooled refrigerators, the freshness of food depends to a large extent on the air circulation in the storage room of air-cooled refrigerators and the temperature difference between various parts in the box. The air circulation in the box is reasonable, and the smaller the temperature difference, the better the freshness preservation performance of the refrigerator. [0003] In the current design of the air passage of most air-cooled refrigerators, most of the air-cooled refrigerators set the evaporator in a separate storage room, and use a complex air duct system to connect the storage room of the evaporator to each storage area, resulting in The structure of the air duct system is complex and takes up a lot of space. [0004] In response to this problem, refrigerators that use air supply distributio...

AI Technical Summary

Problems solved by technology

This type of air-cooled refrigerator uses moving parts to adjust the shading area of ​​the air duct, thereby controlling the air supply volume of each storage area. However, these moving parts may freeze, get stuck and other problems during long-term operation, resulting in improper operation. , prone to failure, resulting in reduced reliability of air-cooled refrigerator refrigeration
