Air-cooled refrigerating box with high-humidity fruit and vegetable chamber and operation control method for air-cooled refrigerating box

Abstract

The invention discloses an air-cooled refrigerating box with a high-humidity fruit and vegetable chamber. The upper part of an air flue cover plate is provided with air outlets; the lower part of the air flue cover plate is provided with a return air inlet; an evaporator is arranged in an air flue; a variable speed fan is arranged above the evaporator; the lower part of the air flue is provided with a honeycomb duct; the lower part of the honeycomb duct is provided with a water pan; a compressor is arranged below the water pan; a refrigerating chamber is arranged at the upper part of the interior of the refrigerating box; the lower part of the interior of the refrigerating box is provided with the high-humidity fruit and vegetable chamber; a fruit and vegetable chamber cover plate is arranged between the high-humidity fruit and vegetable chamber and the refrigerating chamber; the return air inlet is provided with a return air inlet ventilation door; the lower part of the fruit and vegetable chamber cover plate is provided with a fruit and vegetable chamber cover plate ventilation door; and the fruit and vegetable chamber cover plate ventilation door and the return air inlet ventilation door are controlled to be opened or closed through a drive motor and pulley assembly. The air moisture of the refrigerating chamber at the upper part is transferred to the fruit and vegetable chamber in the manner of alternate cooling when the compressor is started and stopped, therefore, the humidity fluctuation in the fruit and vegetable chamber is reduced, and the high-humidity demands of fruits and vegetables are achieved. Meanwhile, when the compressor stops operation, the fan reversely blows over the evaporator at a low speed to perform defrosting.

Description

technical field [0001] The invention relates to an air-cooled refrigerator and an operation control method thereof, in particular to an air-cooled refrigerator with a high-humidity fruit and vegetable compartment and an operation control method thereof. Background technique [0002] The air-cooled refrigerator is to use the cold air generated by the evaporator hidden in the freezer to circulate through the forced circulation of the fan to achieve the purpose of cooling the refrigerator and freezer. Compared with direct cooling refrigerators, air-cooled frost-free refrigerators have the advantages of automatic defrosting, fast cooling speed, good temperature uniformity and precise temperature control. In the research and development of high-end refrigerators with large volumes above 300L, multi-chambers and multi-functions, Feng Cold refrigerators have absolute advantages in cold distribution and other aspects. However, from the analysis of the flow of moisture with the movi...

Problems solved by technology

[0004] Humidification refrigerators have been promoted in the market, but the humidity fluctuation range of these products is still large, and the humidification of the entire refrigerator is carried out; there are also humidifiers installed in the refrigerator, but additional energy consumption will be generated. Both types of refrigerators cannot meet the requirements of high and low humidity storage items at the same time
