Refrigerated freezer and its storage container

Technical field

The invention relates to the field of refrigeration and freezing, and in particular to a refrigerating and freezing device and a storage container thereof.

Background technique

The modified atmosphere preservation technology generally refers to a technique for prolonging the storage life of a food by adjusting the gas atmosphere (gas composition ratio or gas pressure) of the enclosed space in which the storage is located, and the basic principle is: in a certain closed space. A gas atmosphere different from the normal air component is obtained by various adjustment methods to suppress physiological and biochemical processes and microbial activities leading to spoilage of the stored matter (usually the foodstuff). In particular, in the present application, the modified atmosphere preservation will be specifically directed to a modified atmosphere preservation technique that adjusts the proportion of gas components.

It is known to those skilled in the art that normal air components include (by volume percent, hereinafter the same): about 78% nitrogen, about 21% oxygen, about 0.939% rare gas 0.031% carbon dioxide, and 0.03% other gases. And impurities (for example, ozone, nitrogen monoxide, nitrogen dioxide, water vapor, etc.. In the field of modified atmosphere preservation, it is common to use a nitrogen-filled space to reduce the oxygen content in a closed space to obtain a nitrogen-rich and oxygen-poor fresh gas. Atmosphere. Here, those skilled in the art are aware that a nitrogen-enriched gas refers to a gas having a nitrogen content exceeding the nitrogen content of the above-mentioned normal air, for example, the nitrogen content thereof may be 95% to 99% or even higher; and the nitrogen-rich oxygen is rich. The fresh gas atmosphere refers to a gas atmosphere in which the nitrogen content exceeds the above-mentioned normal air nitrogen content and the oxygen content is lower than the oxygen content in the above-mentioned normal air.

The history of modified atmosphere preservation technology dates back to 1821 when German biologists discovered that fruits and vegetables could reduce metabolism at low oxygen levels. But until now, due to the large size and high cost of nitrogen-making equipment traditionally used for gas-conditioning preservation, the technology is basically limited to use in various large-scale professional storage (the storage capacity is generally at least 30 tons). . It can be said that the appropriate gas regulation technology and corresponding equipment can economically reduce and quiet the air-conditioning system, making it suitable for home or individual users.

In the present embodiment, the electrical de-oxygen assembly 200 may further include a diffusion layer 270 and one or more gaskets 260. The diffusion layer 270 is located between the anode plate 220 and the proton exchange membrane 210 and between the cathode plate 230 and the proton exchange membrane 210. The diffusion layer 270 is made of a platinum-plated titanium mesh, which functions to facilitate conduction and allow water vapor to diffuse. At least one washer 260 may be located between the above-mentioned multilayer structures, and each of the washers 260 is an oblong thin ring having the same outer ring size as the cathode plate 230 and the anode plate 220. Each of the washers 260 is made of an elastic material to cushion the pressing force between adjacent layers.

In the embodiment, the electric de-oxygen module 200 further includes: two elastic plates 240 disposed on the outer sides of the anode plate 220 and the cathode plate 230 for tightening the anode plate 220, the proton exchange membrane 210, and the cathode plate. 230. The two elastic plates 240 have a plurality of elastic protrusions 241 on the sides facing the cathode plate 230 and the anode plate 220, and the positions of the elastic protrusions 241 on the two elastic plates 240 correspond to each other, that is, each elastic protrusion Each of the 241 can be mated with a resilient projection 241 on the other plate to press the anode plate 220 and the cathode plate 230 for further clamping of the proton exchange membrane 210.

The axis of the fan shaft is perpendicular to the cathode plate 230 for accelerating the air circulation velocity in the vicinity of the cathode plate 230. Since the side of the cathode plate 230 reacts to generate water, the humidity of the air near the cathode plate 230 is large, and condensation and dripping are likely to occur, which affects food storage inside the storage space. When the electric deactivating oxygen module 200 is turned on, the battery supplies power to the cathode plate 230 and the anode plate 220, respectively, and the first fan 251 can be opened to blow air away from the cathode plate 230 to accelerate the air circulation speed near the cathode plate 230 and prevent The cathode plate 230 generates condensation or water droplets.

Further, since the cathode plate 230 reacts to consume oxygen, the oxygen content in the air near the cathode plate 230 is low, and the oxygen concentration in other portions inside the storage space is relatively high, which tends to cause uneven distribution of oxygen inside the storage space, affecting Food preservation. In the embodiment, the opening of the first fan 251 can also accelerate the air circulation inside the storage space, so that the gas distribution inside the storage space is uniform, and the local oxygen in the storage space is prevented from being too high or too low.

To the anode plate 220, a reactant is supplied to the anode plate 220. Since the internal temperature of the refrigerating and freezing apparatus is generally low, the storage compartment in the refrigerating and freezing apparatus has a relatively humid gas atmosphere, and the air contains a large amount of water vapor. Therefore, the indoor air in the storage room can continuously supply the reactants to the anode plate 220 through the second fan 252, so that it is not necessary to separately provide a water source or a water delivery device for the electric deaeration module 200.
