Humidity control device, preservation box and refrigerator

Abstract

The invention relates to a humidity control device which comprises a humidifying device, a drying device, a humidity sensor and a controller. The humidity sensor is used for detecting the humidity of the environment, obtaining the preservation humidity value, and transmitting the preservation humidity value to the controller. The controller compares the preservation humidity value with a set humidity value, starts the drying device to work when the preservation humidity value is larger than the set humidity value, and starts the humidifying device to work when the preservation humidity value is smaller than the set humidity value. The humidity control device has the advantages that the humidity control device is arranged in a drawer, installed in a refrigeration chamber of a refrigerator, powered by the refrigeration chamber and driven by the controller to run, the related humidity is set according to stored objects, the application range is wide, and humidity control is accurate; the humidity control drawer is easily combined with the refrigerator, only a circuit interface needs to be added without largely changing the structure of the refrigerator compared with an ordinary drawer, and universality is high. The invention further relates to a preservation box in the refrigerator and the refrigerator.

Description

technical field [0001] The invention relates to the field of refrigerators, in particular to a humidity control device, a preservation box and a refrigerator. Background technique [0002] As a kind of household food storage, the refrigerator needs to store more and more types of food. Among them are foods that require high humidity, such as fruits and vegetables, and foods that require low humidity, such as noodles and dry goods, to meet the needs of the market. The existing humidity environment in the refrigerator can no longer meet the needs of consumers. [0003] With the application of air-cooling technology in refrigerators, on the one hand, air-cooling technology can make the temperature and humidity in the refrigerator more uniform, but on the other hand, it has also caused some problems. For example, because there is no absolutely sealed space in the refrigerator, the refrigerator The wind flowing inside will take away the moisture in the air, making the space of t...
