Description

Automatic liquid supplementing module, air regulating device and refrigerator Technical Field The invention relates to a fresh-keeping technology, in particular to an automatic liquid supplementing module, an air conditioning device and a refrigerator. Background The modified atmosphere preservation technology is increasingly used as an advanced technology for effectively prolonging the shelf life of foods by adjusting the components of the ambient gas, and therefore, a refrigerating and freezing device with the function is also favored in the market. The requirements of the modified atmosphere fresh-keeping environment are different for different types of food materials. For example, in a high-concentration oxygen environment, the respiration of food materials such as fruits and vegetables can be accelerated, so that the content of organic matters is reduced, and nutrients are lost, so that the food materials are more suitable for being stored in a low-oxygen fresh-keeping environment. In contrast, for food materials such as meat, the low concentration oxygen environment may affect the color and mouthfeel, so they need to be stored in a high oxygen fresh-keeping environment to maintain optimal quality. Existing air conditioning devices are generally constructed to include a cathode, an anode, and an electrolyte filled therebetween. These devices contact the air in the space through the cathode, causing the oxygen to undergo a reduction reaction at the cathode, specifically of the formula O 2+2H2O+4e-→4OH-. At the same time, the anode is subjected to oxidation reaction to generate oxygen, and the reaction formula is 4OH -→O2+2H2O+4e-. However, in the practical application process, as the electrochemical reaction proceeds, the electrolyte in the air conditioning device gradually decreases. When the electrolyte is reduced to a certain extent, not only the efficiency of the electrochemical reaction is affected, but even the reaction may not be performed. Therefore, timely replenishment of electrolyte becomes a key to maintaining normal operation of the air conditioning device. At present, technologies for supplementing liquid by adopting an electric control ball valve or a power pump exist in the market, but the schemes have complex structures and high cost. In view of the foregoing, there is a need for an improved solution to the above-mentioned problems.
