Refrigerator storage devices and refrigerators

Abstract

The present invention provides a storage device for a refrigerator, comprising: a body part, which defines a storage space inside; a cover plate, used to open or close the storage space, and one or more elastic films are arranged on it; and a vacuum pump disposed outside the main body for sucking air in the storage space; wherein the elastic membrane is configured to move toward the storage space as the air in the storage space is sucked by the vacuum pump The storage space is deformed, so that the use volume of the storage space is reduced. The storage device of the refrigerator of the present invention and the refrigerator set one or more elastic films on the cover plate, and utilize the vacuum pump arranged outside the main body to suck the air in the storage space, so that the elastic films are configured to follow the movement of the storage space. The air is sucked by the vacuum pump and deformed toward the storage space, thereby reducing the usable volume of the storage space. The invention also provides a refrigerator.

Description

technical field [0001] The invention relates to the technical field of freezing and refrigerating devices, in particular to a refrigerator storage device and a refrigerator. Background technique [0002] The traditional cold storage of fruits and vegetables is mainly achieved through low temperature. There are many factors that affect the preservation of fruits and vegetables, mainly temperature, humidity, gas composition, etc. There are many methods for controlling the atmosphere of fruits and vegetables, the main methods are as follows. One is to pass a certain amount of inert gas into the storage space to discharge the air in it, so as to achieve an atmosphere-controlled environment that is beneficial to the storage of fruits and vegetables; the disadvantage of this method is that it is costly and requires an inert gas generating device, which is not conducive to popularization. The other is to use a combination of a vacuum pump and an oxygen-enriched membrane to reduce...

AI Technical Summary

Problems solved by technology

One is to introduce a certain amount of inert gas into the storage space to discharge the air in it, so as to achieve a controlled atmosphere environment that is conducive to the storage of fruits and vegetables; the disadvantage of this method is that it is costly and requires an inert gas generating device, which is not conducive to popularization

The other is to use a combination of a vacuum pump and an oxygen-enriched membrane to reduce the oxygen content in the storage space by making the extracted gas have more oxygen content, thereby inhibiting the respiration of fruits and vegetables; the disadvantage of this method is that it The effect achieved is limited, the oxygen concentration can only be reduced by about 3%, and the freshness effect of fruits and vegetables is not significantly improved

It can be seen that the current refrigeration and preservation of fruits and vegetables is mainly achieved by adding functional components to the refrigerator box. The installation of devices is an indirect adjustment method, which is not conducive to the realization of
