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

The invention provides a refrigerating device for cold storage. The refrigerating device comprises a storage drawer, an electrolytic oxygen removal component, a touch sensing device and an electric-air valve. The electrolytic oxygen removal component is used for consuming oxygen in air in a storage space, so that nitrogen-rich and oxygen-lean gas atmosphere benefiting food preservation is obtainedin the space. Through reduction of the oxygen content in the gas atmosphere of the storage space, the aerobic respiration intensity of food (especially fruits and vegetables) is reduced, and meanwhile the basic respiration is ensured; anaerobic respiration of the food is avoided, so that the purpose of the long-time preservation of the food is achieved. When the touch sensing device detects thata user is to open the storage drawer, a through hole in the drawer is opened through the electric-air valve, so that the interior and exterior of the storage space communicate with each other; and thedifference between internal pressure and external pressure of the drawer is eliminated, and the problem that the drawer is hard to open due to installation of the electrolytic oxygen removal component is solved. The refrigerating device enables the user to conveniently open the storage drawer in a labor-saving manner, 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] 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 ...
