Description

Air flow guiding device for fresh-keeping equipment and fresh-keeping equipment Technical Field The invention belongs to the technical field of food preservation equipment, and particularly provides an airflow guiding device for preservation equipment and the preservation equipment. Background The prior preservation equipment mainly comprises a refrigerator, a freezer and the like, and the food materials in the preservation equipment are preserved mainly by reducing the temperature of an internal preservation chamber. But the nature of oxygen in the air is very active and can still cause various spoilage reactions and spoilage of the food. Oxygen can destroy nutrients, pigments, flavors and other ingredients of the food by participating in oxidation reactions. At the same time, oxygen is also a necessary condition for the growth of aerobic microorganisms, and under aerobic conditions, the deterioration reaction rate caused by the proliferation of microorganisms is accelerated, resulting in a shortened shelf life of foods. In order to overcome the above problems, some fresh-keeping apparatuses are further provided with an air-conditioning device to consume oxygen in the fresh-keeping compartment through the air-conditioning device, thereby reducing the content of oxygen in the fresh-keeping compartment. Specifically, the air conditioner comprises a cathode, an anode and electrolyte filled between the cathode and the anode, and the air conditioner is contacted with air in the fresh-keeping compartment through the cathode, so that oxygen undergoes a reduction reaction at the cathode, namely O 2+2H2O+4e-→4OH-. And the anode is subjected to oxidation reaction to generate oxygen, namely 4OH -→O2+2H2O+4e-. Thereby the air regulating device can regulate the oxygen concentration in the fresh-keeping compartment. However, the air conditioner in the existing fresh-keeping equipment can only independently adjust the oxygen concentration in one fresh-keeping compartment, and if the oxygen concentration in a plurality of fresh-keeping compartments needs to be adjusted, one air conditioner needs to be respectively configured for each fresh-keeping compartment. Therefore, the cost of the fresh-keeping equipment is increased, more space in the fresh-keeping equipment is occupied, and the volume rate of the fresh-keeping equipment is low.
