Drawer module and refrigerating and freezing device with drawer module

Abstract

The invention relates to a drawer module and a refrigerating and freezing device with the drawer module. The drawer module comprises a cylinder and a controlled atmosphere membrane module, wherein drawer space is limited in the cylinder; an accommodating cavity is limited in the top wall of the cylinder, and is communicated with the drawer space; the controlled atmosphere membrane module is mounted in the accommodating cavity, and has a controlled atmosphere membrane and an oxygen-enriched gas collecting cavity; and the controlled atmosphere membrane module is configured to enable more oxygen in the accommodating cavity to enter the oxygen-enriched gas collecting cavity through the controlled atmosphere membrane compared with nitrogen in the accommodating cavity. The drawer module can form rich nitrogen and lean oxygen in the drawer space to facilitate a gas atmosphere for food preservation, reduces the aerobic respiration strength of fruits and vegetables, and meanwhile, guarantees basic breathing effect to prevent anaerobic respiration of the fruits and the vegetables so as to achieve the purpose of long-time preservation of the fruits and the vegetables. The drawer module occupies no storage space, and can prevent collision from damaging the controlled atmosphere membrane module.

Description

technical field [0001] The invention relates to the technical field of refrigerator storage, in particular to a drawer assembly and a refrigerating and freezing device with the drawer assembly. Background technique [0002] A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. With the improvement of the quality of life, consumers have higher and higher requirements for the preservation of stored food, especially for the color and taste of food. Therefore, the stored food should also ensure that the color, taste, and freshness of the food remain unchanged as much as possible during the storage period. At present, in order to better store food in the market, there is only one kind of vacuum preservation. The vacuum preservation methods that are often used are vacuum bag preservation and vacuum drawer preservation. [0003] Using vacuu...

AI Technical Summary

Problems solved by technology

[0004] Vacuum drawers are used to keep fresh. Since the drawers and cylinders are rigid structures, they must maintain a vacuum state. The requirements for the vacuum system are very high, and the sealing performance of the drawers and cylinders is very high. More fresh air, more energy consumption

Moreover, in a vacuum environment, it is difficult for food to receive cold, which is not conducive to food storage.

In addition, due to the vacuum environment, the user needs to spend a lot of effort to open the drawer every time, causing inconvenience to the user

Although some refrigerators can ventilate the drawer chamber through the vacuum system, this will cause the user to wait for a long time, and the timeliness is poor.

A long vacuum time will also cause serious deformation of the refrigerator drawer assembly, that is, the existing drawer assembly with a vacuum structure cannot complete vacuum preservation well, and the strength of the drawer is required to be very high. The implementation requirements are high and the cost is high.
