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

[0032] 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 , figure 2 As shown, the refrigerator includes: a cabinet, a storage drawer 100 , a touch sensing device 500 and an electric gas valve 300 . 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. 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 of pairs...

Abstract

A refrigeration and freezing device, comprising a storage drawer (100), an electrolytic oxygen removal assembly (200), a touch sensing device (500) and an electric air valve (300). The electrolytic oxygen removal assembly (200) is used for consuming oxygen in a storage space so that nitrogen-rich oxygen-deficient air is obtained in the space so as to benefit a gas atmosphere for food preservation. The intensity of the aerobic respiration of food, particularly fruits and vegetables, is decreased by means of decreasing the content of oxygen in the storage space, simultaneously ensuring basic respiratory action and preventing the anaerobic respiration of the food, thereby achieving the goal of long-term preservation of the food. When the touch sensing device (500) detects that a user is about to open the storage drawer (100), the electric air valve (300) opens a through hole on the drawer (100) so that the interior and exterior of the storage space communicate, the pressure difference between the interior and exterior of the drawer being eliminated, and thus the problem in which a drawer is difficult to open due to the mounting of the electrolytic oxygen removal assembly (200) is solved; a user may open the storage drawer (100) with less effort, and the usage experience of the user is thus 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 ...
