An air-cooled refrigerator and its control method

Abstract

The invention discloses an air-cooling refrigerator and a control method thereof. An independent moisture control area is arranged in a refrigeration chamber of the air-cooling refrigerator. Two independent moisture control air path circulating systems are arranged in the moisture control area. One of the independent moisture control air path circulating systems is a refrigeration moisture control air path circulating system, and the other independent moisture control air path circulating system is a freezing moisture control air path circulating system. The refrigeration moisture control air path circulating system comprises a refrigeration moisture control air-supplying air flue, a refrigeration moisture control air-returning air flue, a refrigeration moisture control air-supplying air door and a refrigeration moisture control air-returning air door. The freezing moisture control air path circulating system comprises a freezing moisture control air-supplying air flue, a freezing moisture control air-returning air flue, a freezing moisture control air-supplying air door and a freezing moisture control air-returning air door. The air-cooling refrigerator and the control method thereof have the beneficial effects that switching between the two independent moisture control air path circulating systems is utilized, and different forms of combination and cooperation of the temperatures of all evaporators and the starting time of all the air doors are combined, so that precise adjustment of humidity in the moisture control area is achieved; the humidity adjustment range is wide; and the precise requirements of various types of food for the humidity are met.

Description

technical field [0001] The invention relates to the technical field of refrigeration appliances, in particular to an air-cooled refrigerator and a control method thereof. Background technique [0002] At present, the air-cooled refrigerators on the market have the function of dry and wet partitions. The main principle is to use the dehumidification effect of the air circulation of the air-cooled refrigerator itself. Through simple control, an area is divided into dry areas. The relative humidity is generally below 45%. It is used to store dried fruits and dry goods, etc.; the other area is used to store fruits, vegetables, etc., so that the relative humidity of this area can be kept above 95% through the combination of a sealed cover and a moisture-permeable membrane. [0003] This technology has several disadvantages. First, the humidity mode is fixed and cannot be adjusted according to the needs of users. Especially in the wet area, the method of physical sealing is used ...

AI Technical Summary

Problems solved by technology

[0003] This technology has several disadvantages. First, the humidity mode is fixed and cannot be adjusted according to the needs of users.

Especially in the wet area, the method of physical sealing is used to achieve moisture retention. If the drawer is not used for a long time during use, harmful gas will easily accumulate, which is not good for the freshness of fruits and vegetables. The residual heat of fruits and vegetables will easily form condensation on the drawer

2. When the refrigerator is closed and the refrigerator is not cooling, the dry area will lose its function, and the dry goods in the dry area will quickly absorb moisture and become moldy

3. The humidity between 45% and 90% is not covered, which cannot meet the precise requirements of food for temperature and humidity
