Dry storage device and ventilation method thereof

Abstract

The invention provides a dry storage device and a ventilation method thereof. The dry storage device comprises a shell which defines a drying chamber, wherein the shell is provided with an air supply hole. The ventilation method of the dry storage device comprises the following steps: acquiring a starting signal for triggering the dry storage device to ventilate; opening the air supply hole according to the starting signal to provide air cooled by a cold source to the drying chamber; measuring humidity in the drying chamber, and closing the air supply hole after the humidity reaches a first preset humidity value to heat the drying chamber in a sealed state. By using the technical scheme of the invention, ventilation is started according to the starting signal, and the ending of the ventilation is controlled according to the humidity so as to guarantee that supplied low-temperature air can be used for substituting moist air in the drying chamber completely, so that the relative humidity in the drying chamber can be guaranteed to meet the requirement on long-term storage of dry cargoes after the ventilation is ended, the waste of electric energy used by refrigeration and air supply in long-term air supply can also be avoided, and foods are effectively prevented from getting mildew or becoming damp again.

Description

technical field [0001] The invention relates to the technical field of refrigerators, in particular to a dry storage device and an air exchange method thereof. Background technique [0002] Along with consumers' expectations for a healthier lifestyle, the proportion of dry food ingredients such as wolfberry, tea, shiitake mushrooms, longan, and cordyceps sinensis is gradually increasing in the diet structure. However, these dry food ingredients are very difficult to store. If they are stored at room temperature, under the condition of poor ventilation, they will easily change color and deteriorate after a long time of storage, resulting in the loss of nutrients; The impact of food leads to dampness, mold and deterioration. How to store dry food ingredients for a long time is a problem to be solved. [0003] In order to solve this problem, a room with adjustable humidity has been added on the basis of the refrigeration function of the refrigerator in the prior art. For exam...

Problems solved by technology

[0004] The drying room constructed in the prior art forms a dry environment with low relative humidity in the enclosed space by blowing cold air with a low temperature into the drying room, and then using the principle that the relative humidity changes with temperature. However, the traditional air supply control does not Considering the moisture contain
