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 invention provides a refrigerating and freezing device, and the refrigerating and freezing device can be a refrigerator, a freezer, and 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 for a refrigerating and freezing device. The storage compartment of the refrigerator includes: a refrigerating compartment and a freezing compartment below the refrigerating compartment ( figure 1 Only part of the refrigerated compartment is shown). The storage drawer 100 is composed of a cylinder body 111 and a pull-out part 112, and the storage drawer 100 is arranged at the bottom of the refrigerating compartment of the refrigerator. The above-mentioned refrigeration and freezing device further includes: an inner tank 410, which is arranged inside the box body. A plurality...

Abstract

The invention provides a refrigerating and freezing device. The refrigerating and freezing device comprises a storage drawer, an electrolysis oxygen removal assembly and a pore opening and closing device. The electrolysis oxygen removal assembly is used for consuming oxygen in the air in a storage space, so that rich nitrogen and poor oxygen can be obtained in the space to benefit the gas atmosphere for food preservation. The gas atmosphere can reduce the intensity of aerobic aspiration of food (particularly fruits and vegetables) by decreasing the content of oxygen in the storage space, ensure basic respiratory action and prevent anaerobic respiration of the food, so that the purpose of long-term preservation of the food is achieved. According to the refrigerating and freezing device, when a user is about to open the storage drawer, the pore opening and closing device can open a pore, arranged in a grabbing groove, of the device, so that the inside and the outside of the storage spacecan be communicated, the pressure difference between the inside and the outside of the drawer can be eliminated, and the problem that the drawer is difficult to open due to mounting of the electrolysis oxygen removal assembly is solved. The user can open the storage drawer more effortlessly, and the use experience of the user 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] Modified atmosphere preservation technology generally refers to the technology of prolonging the life of food storage by adjusting the gas atmosphere (gas composition ratio or gas pressure) in the closed space where the storage is located. The basic principle is: in a certain closed space A gas atmosphere different from normal air components is obtained through various adjustment methods to inhibit the physiological and biochemical processes and microbial activities that cause the storage (usually food) to deteriorate. In particular, in this application, the discussed modified atmosphere fresh-keeping will be specifically aimed at the modified-atmosphere fresh-keeping technology that adjusts the ratio of gas components. [0003] In some existing refrigerators, an oxygen reduction device is arranged in a ...
