Problems solved by technology
But until now, due to the large size and high cost of nitrogen-generating equipment traditionally used for controlled atmosphere preservation, this technology has basically been limited to use in various large-scale professional storages (storage capacity is generally at least 30 tons or more).
It can be said that what kind of appropriate gas adjustment technology and corresponding devices can be used to economically miniaturize and quiet the air conditioning system, making it suitable for families or individual users, is a problem that technicians in the field of air conditioning and fresh-keeping have been eager to solve but have never been able to solve. Technical problems that can be successfully solved

Embodiment Construction
[0033] Such as figure 1 , figure 2As shown, the embodiment of the present invention firstly provides a storage container 100 for a refrigerating and freezing device, including: a box body 110 and an electrolytic deoxygenation assembly 200 . A storage space is defined inside the box body 110 , and an opening is provided on the top surface of the box body 110 . The electrolytic deoxygenation component 200 is formed at the above-mentioned opening, configured to consume oxygen inside the controlled atmosphere fresh-keeping space through electrolytic reaction.
[0034] In this embodiment, the opening is a rectangular opening for installing the electrolytic deoxygenation component 200 . The size of the electrolytic deoxygenation component 200 is adapted to the size of the opening so that it can completely close the opening and prevent gas exchange between the inside of the storage space and the outside.
[0035] Such as image 3 As shown, the electrolytic deoxygenation assembly...

A refrigeration and freezing device and an oxygen removal control method thereof, the refrigeration and freezing device having a storage container (100) inside thereof, an electrolytic oxygen removal assembly (200) being provided on a surface of the storage container (100), and the electrolytic oxygen removal assembly (200) comprising: an anode plate (220), a cathode plate (230), a proton exchange membrane (210) and a battery (211), two electrodes of the battery (211) being controllably connected to the anode plate (220) and the cathode plate (230), and the electrolytic oxygen removal assembly (200) being configured to consume oxygen inside the storage container (100) by means of an electrolytic reaction. when it is detected that the oxygen concentration of the storage space (100) is low, the voltage applied to the anode and cathode plates by the battery (211) is proportionately increased, so as to improve the reaction speed; when it is detected that the oxygen concentration in the storage space (100) is high, the voltage of the battery (211) is proportionately reduced, so as to reduce the power consumption of the battery (211), and ensure that the electrolytic oxygen removal assembly (200) consumes the oxygen in the storage space (100) at a stable speed, thereby improving the operating stability of the electrolytic oxygen removal assembly (200).
Description
technical field [0001] The invention relates to the field of refrigerating and freezing, in particular to a refrigerating and freezing device and a deoxygenation control method thereof. 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] Those skilled in the art all know...
