Abstract
The invention provides a humidity controlling device and a humidity controlling sheet used for a refrigerator, and a preparation method thereof, wherein the humidity controlling sheet has a laminatedstructure and successively includes a water absorption layer, a binder layer and a reversible humidity controlling layer, and is prepared in a coating and roller pressing manner. In the invention, thehumidity controlling device, produced with the humidity controlling sheet, is used in a storage box in the refrigerator; on the basis of the humidity, detected by a temperature sensor, in a refrigerating chamber, if the humidity is too high, the humidity controlling device can absorb the moisture in the refrigerating chamber; if the humidity is too low, the humidity controlling device can releasethe absorbed moisture; if the humidity is normal, the humidity controlling device is idle and does not absorb and release moisture. The humidity controlling device can control the humidity in the refrigerating chamber to be stable.
Description
technical field [0001] The invention relates to a humidity control module for a refrigerator, in particular to a humidity control module and a humidity control sheet for a refrigerator and a preparation method thereof. Background technique [0002] The low temperature in the storage room of the refrigerator is conducive to keeping the freshness of fruits and vegetables, but due to the convection of the air in the refrigerator, the humidity in the refrigerator is relatively low, generally 30% to 60%. However, the best storage humidity for fruits and vegetables is generally around 90%. If the fruits and vegetables are directly placed in the refrigerator, most of the moisture in the fruits and vegetables will be easily lost, which is not conducive to freshness preservation. In order to reduce the loss of water, people generally put fruits and vegetables into fruit and vegetable boxes. The airtightness of the fruit and vegetable box is relatively good, and the humidity is rela...
