Description
Technical Field
The invention relates to a refrigerating and freezing device, in particular to a refrigerator.
Background
Modified atmosphere technology generally refers to technology for prolonging the storage life of food by adjusting the gas atmosphere (gas component ratio or gas pressure) of a closed space where stored objects are located, and the basic principle is as follows: in a certain closed space, a gas atmosphere different from normal air components is obtained through various regulation modes so as to inhibit physiological and biochemical processes and activities of microorganisms which cause the putrefaction and deterioration of stored objects (generally food materials). In particular, in the present application, the modified atmosphere preservation discussed will be specific to modified atmosphere preservation techniques that regulate the proportions of the gas components.
As is known to those skilled in the art, the normal air composition includes (in volume percent, the same applies hereinafter): in the modified atmosphere preservation field, nitrogen-rich gas is generally used to obtain a nitrogen-rich and oxygen-poor preservation gas atmosphere by filling a nitrogen-rich gas into a closed space to reduce the oxygen content, wherein the nitrogen-rich gas is a gas with a nitrogen content exceeding that of the normal air, and the nitrogen content can be 95% -99% or even higher, for example, while the nitrogen-rich and oxygen-poor preservation gas atmosphere is a gas atmosphere with a nitrogen content exceeding that of the normal air and an oxygen content lower than that of the normal air.
The history of modified atmosphere technology dates back to 1821 German biologists that fruits and vegetables can reduce the onset of metabolism at low oxygen levels. However, until now, the technology has been limited to use in large professional storage facilities (storage capacity is typically at least 30 tons) due to the large size and high cost of the nitrogen generating equipment traditionally used for modified atmosphere preservation. It can be said that the adoption of proper gas conditioning technology and corresponding devices can economically miniaturize and mute the gas conditioning system, so that the system is suitable for families or individual users, and is a technical problem which is desired to be solved by technicians in the field of gas conditioning preservation and is not successfully solved all the time.

The distance of the opening from its nearest one of the air duct openings 431 is less than a preset length, which may be set to 10cm, to ensure that the opening is located adjacent to the air duct opening 431.
An electrolytic oxygen scavenging assembly 200 is removably disposed at the opening and is configured to consume oxygen from the interior of the storage compartment via an electrolytic reaction. In this embodiment, the electrolytic oxygen removal assembly is disposed on the opening of the inner container 430, so that the user can conveniently mount or dismount the electrolytic oxygen removal assembly 200 after opening the door of the refrigerator.
In this embodiment, electrolytic oxygen removal assembly 200 is positioned adjacent to air vent 431 of the refrigerator. The air duct opening 431 is a junction of cold air and hot air, so that the humidity is high, and the water vapor content in the air is rich.

The battery may be disposed within a foam layer of the refrigerator cabinet. The side of the cathode plate 230 facing away from the proton exchange membrane 210 faces the storage compartment, and the cathode plate 230 is in contact with the air inside the storage compartment. The side of the anode plate 220 opposite to the pem 210 faces the air duct, and the anode plate 220 is in contact with the air in the air duct. That is, the electrolytic oxygen removal assembly 200 has at least a 3-layer structure, in order, an anode plate 220, a proton exchange membrane 210, and a cathode plate 230.

Preferably, the proton conducting polymer is polystyrene sulfonic acid (PSSA) or carboxymethyl cellulose (CMC). The porous membrane is Polytetrafluoroethylene (PTFE) or Fluorinated Ethylene Propylene (FEP) or polyolefin film or fluorinated ethylene propylene or glass fiber or ceramic fiber or polymer fiber; the active component is silica gel suitable for electroosmotic flow, and the dispersed silica gel concentration is no more than 5% of the mass of the proton exchange membrane.
In this embodiment, the electrolytic oxygen scavenging assembly 200 may further comprise: two elastic plates 240, respectively disposed at the outer sides of the anode plate 220 and the cathode plate 230, for clamping the anode plate 220, the proton exchange membrane 210 and the cathode plate 230.

Electrolytic oxygen scavenging assembly 200 further comprises: a fan. The fan may be a micro axial flow fan. The blower is disposed on a side of the anode plate 220 opposite to the pem 210, and has a rotation axis perpendicular to the anode plate 220 for blowing the water vapor near the air duct opening 431 toward the anode plate 220. The reactant of the anode plate of the electrolytic oxygen removal assembly 200 of the present embodiment is water vapor, and therefore, the anode plate needs to be supplemented with water vapor continuously so that the electrolytic reaction can be continuously performed. When the electrolytic oxygen removal assembly 200 is turned on, the batteries respectively supply power to the cathode plate 230 and the anode plate 220, and the blower is turned on, and blows air and water vapor in the air to the anode plate 220 simultaneously when the blower blows air to the anode plate 220 so as to provide reactants to the anode plate 220. Because the air near the air vent 431 is able to provide sufficient reactant to the anode plate 220, there is no need to provide a separate water source or water delivery device for the electrolytic oxygen removal assembly 200.
In this embodiment, the multi-layer structure of the cathode plate 230, the anode plate 220, and the proton exchange membrane 210 are integrated into a container 280 to facilitate the assembly and disassembly of the electrolytic oxygen removal assembly 200.

As shown in FIG. 6, the X direction is defined as the length direction of the housing box 280, Y is the width direction, and Z is the height direction. The top of the containing box 280 is opened with a rectangular mounting opening for installing each component in the electrolytic oxygen removing assembly 200, and the size of the mounting opening is matched with the size of the cathode plate 230 and the anode plate 220. The bottom surface of the containment box 280 is hollowed out to allow gas to pass through, and in this embodiment, a cross bracket 286 is also secured to the bottom surface of the containment box 280 to support the various components of the electrolytic oxygen removal assembly 200.

The layer arrangement direction of the multi-layer structure coincides with the height direction of the accommodation box 280. In this embodiment, the multilayer structure inside the housing box 280 is, from top to bottom: a spring plate 240, a gasket 260, a cathode plate 230, a gasket 260, a diffusion layer 270, a proton exchange membrane 210, a diffusion layer 270, a gasket 260, an anode plate 220, a gasket 260, and a spring plate 240. When the electrolytic oxygen removal assembly 200 is installed, the assembled electrolytic oxygen removal assembly 200 is inserted entirely into the opening of the inner container 430, and when the containment box 280 is inserted entirely into the interior of the inner container 430, the installation of the electrolytic oxygen removal assembly 200 is completed. If the user does not need the oxygen removal function of the storage compartment, the entire storage case 280 may be removed.
The refrigerator of the present embodiment includes: electrolytic oxygen scavenging assembly 200. The electrolytic oxygen scavenging assembly 200 is used to deplete the air in the storage compartment to obtain a nitrogen-rich and oxygen-lean atmosphere in the space that facilitates the preservation of food. The gas atmosphere reduces the oxygen content in the storage room, reduces the strength of aerobic respiration of food (especially fruits and vegetables), ensures the basic respiration, and prevents the food from anaerobic respiration, thereby achieving the purpose of long-term fresh-keeping of the food.
