Problems solved by technology

However, due to the oxygen reduction device inside these refrigerators, the oxygen concentration in the closed space will gradually decrease, and the air pressure will become lower at the same time.
This situation is likely to cause a pressure difference between the inside and outside of the closed space, making it difficult for users to open

Embodiment Construction

[0033] The present invention provides a refrigerating and freezing device, and the refrigerating and freezing device can be a refrigerator, a freezer, or the like. In this embodiment, the refrigerating and freezing device is an air-cooled refrigerator, such as Figure 1 to Figure 3 As shown, the refrigerator includes: a box body and a storage drawer 100 . The inside of the box body forms a storage compartment of the refrigerating and freezing device. The storage compartment of the refrigerator includes: a refrigerating compartment and a freezing compartment ( figure 1 Only part of the refrigerator compartment is shown). The storage drawer 100 is composed of a cylindrical body 111 and a drawing part 112, and the storage drawer 100 is arranged at the bottom of the refrigerating compartment of the refrigerator. The above-mentioned refrigerating and freezing device further includes: an inner pot 410, and the inner pot 410 is arranged inside the box body. A plurality of pairs o...

Abstract

The invention provides a refrigerating and freezing device, which comprises: a storage drawer, an electrolytic deoxygenation assembly and an air hole opening and closing device. The electrolytic deoxygenation component is used to consume the oxygen in the air in the storage space, so as to obtain a nitrogen-rich and oxygen-poor gas atmosphere in the space, which is beneficial to food preservation. The gas atmosphere reduces the intensity of aerobic respiration of food (especially fruits and vegetables) by reducing the oxygen content in the storage space, while ensuring basic respiration and preventing anaerobic respiration of food, thereby achieving the purpose of long-term food preservation. In the refrigerating and freezing device of the present invention, when the user is about to open the storage drawer, the air hole opening and closing device can open the air hole arranged in the grip groove, so that the inside and outside of the storage space are communicated, eliminating the pressure difference between the inside and outside of the drawer, and solving the problem caused by the installation of electric release. The drawer is difficult to open due to oxygen components. It is convenient for the user to open the storage drawer with less effort, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of refrigeration and freezing, in particular to a refrigeration and freezing device. Background technique [0002] The modified atmosphere preservation technology generally refers to the technology of prolonging the storage life of food by adjusting the gas atmosphere (gas composition ratio or gas pressure) in the closed space where the stored goods are located. The basic principle is: in a certain closed space , through various adjustment methods to obtain a gas atmosphere different from the normal air composition, so as to inhibit the physiological and biochemical processes and microbial activities that lead to the spoilage of stored materials (usually food materials). In particular, in this application, the modified atmosphere fresh-keeping discussed will be specifically aimed at the modified atmosphere fresh-keeping technology that adjusts the proportion of gas components. [0003] In some existing refrigerators,...
