Refrigerator and humidity control method for refrigerating chamber of refrigerator

Abstract

The invention discloses a refrigerator and a humidity control method for a refrigerating chamber of the refrigerator. The refrigerator comprises a refrigerator body, a door, a compressor, an evaporator, a fan, a first temperature sensor, a second temperature sensor, a refrigerating chamber moisture preserving mode selecting device and a controller, wherein the first temperature sensor is used fordetecting the temperature in the refrigerating chamber, the second temperature sensor is used for detecting the temperature of the evaporator, the refrigerating chamber moisture preserving mode selecting device is used for switching over the refrigerating chamber between a high moisture preserving mode and a normal moisture preserving mode, and the controller is respectively connected with the first temperature sensor, the second temperature sensor, the compressor, the fan and the refrigerating chamber moisture preserving mode selecting device. A user can use the refrigerating chamber moisture preserving mode selecting device to select the moisture preserving modes of the refrigerating chamber, after the moisture preserving modes are selected, the controller judges needs of the user so asto switch over the refrigerating chamber between the high moisture preserving mode and the normal moisture preserving mode, different moisture preserving needs of the user can be met, and after the high moisture preserving mode is started by the user, the humidity in the refrigerating chamber can be kept in a high humidity value range.

Description

technical field [0001] The invention relates to the technical field of refrigeration, in particular to a refrigerator and a method for controlling the humidity of a refrigerating room of the refrigerator. Background technique [0002] Traditional refrigerators usually use fans to achieve forced convection circulation of cold air to indirectly cool food. As the cold air circulates in the refrigerator, the moisture in the food in the box is continuously taken away by the cold air and frosts on the evaporator. Therefore, the maximum humidity in the cold storage room of a traditional refrigerator does not exceed 75% RH, and the average humidity can only be maintained at 50 Around %RH or even lower. [0003] When the dry consumption (weight loss) of most fruits and vegetables exceeds 5%, there will be obvious signs of freshness decline such as wilting. Especially for fruits, it is impossible to return to the original state after the consumption reaches 5%. The water evaporatio...

AI Technical Summary

Problems solved by technology

[0004] The humidity in the cold room of traditional refrigerators is low, which cannot meet the high moisturizing and fresh-keeping storage requirements of fruits and vegetables, which will easily lead to dehydration and air-drying of fruits and vegetables, reducing storage time and edible value
