Drying device and refrigerator equipped with the drying device

Abstract

The invention provides a drying device which comprises a drying chamber with one or more air inlets, an opening part used for storing articles and a cover body used for covering the opening part, a cooling unit for generating cooling gas with temperature lower than that of gas in the drying chamber, and a control part for controlling a cooling gas replacement process and a process of increasing the temperature of the gas in the drying chamber to be alternately conducted, wherein the cooling gas replacement process is that the cooling gas generated by the cooling unit replaces the gas in the drying chamber through the air inlets of the drying chamber; the process of rising the temperature of the gas in the drying chamber is that the gas in the drying chamber is increased after the cooling gas replacement process is finished. The invention further provides a refrigerator with the drying device. The drying device has the characteristics that the drying effect is good, the article storage quality can be effectively improved, and the article storage time can be prolonged.

Description

Technical field [0001] The invention relates to a drying device and a refrigerator equipped with the drying device. Background technique [0002] The current refrigerator technology can basically realize the setting of different storage temperatures for different types of foods. However, with consumers’ expectations for a healthier lifestyle, the proportion of dried foods such as shiitake mushrooms and ginseng in the diet has gradually increased. What comes is the question of how to store these dry goods for a long time under the corresponding temperature and humidity conditions. [0003] To solve this problem, it is a more promising solution to equip a compartment with adjustable humidity on the basis of the refrigerator's refrigeration function. As such a compartment having a drying function, for example, Patent Document 1 discloses a refrigerator having a drying compartment. The drying chamber is formed as an independent space in the refrigerating chamber of the refrigerator, ...

Problems solved by technology

[0006] However, the disadvantage of the above solution is that it needs to use an auxiliary electric heating device to heat the air before it flows into the drying chamber, which will cause a large fluctuation range of the gas temperature in the drying chamber, and increase power consumption and high manufacturing cost
