Detailed Description
As shown in fig. 1, the embodiment of the present invention first provides a storage container 100 for a refrigerating and freezing apparatus, including: box body 110, electrolysis dehumidification subassembly 200. A storage space is defined in the box body 110, and a mounting opening is formed in the surface of the box body 110. The electrolytic dehumidifying module 200 is formed at the installation opening and configured to consume water vapor inside the storage space through an electrolytic reaction.
In the present embodiment, the mounting opening is a rectangular opening for mounting the electrolytic dehumidification module 200. The size of the electrolytic dehumidification assembly 200 is matched with the size of the mounting opening, so that the mounting opening can be completely sealed, and gas exchange between the inside of the storage space and the outside is prevented.
As shown in fig. 2 to 4, the electrolytic dehumidifying assembly 200 includes: an anode plate 220, a cathode plate 230, and a proton exchange membrane 210 sandwiched between the cathode plate 230 and the anode plate 220. The power supply for supplying power to the electrolytic dehumidification assembly 200 may be disposed on the storage container, or may be disposed outside the storage container, for example, may be disposed on an inner container of a refrigerator, so as to facilitate installation and detachment by a user. The surface of the anode plate 230 facing away from the proton exchange membrane 210 is at least partially exposed inside the storage space, and the surface of the cathode plate 220 facing away from the proton exchange membrane 210 is at least partially exposed outside the storage space. That is, the electrolytic dehumidification assembly 200 has at least 3 layers of structures, which are a cathode plate 230, a proton exchange membrane 210 and an anode plate 220 from top to bottom, wherein the cathode plate 230 faces the outside of the storage space, and the anode plate 220 faces the inside of the storage space. Each layer of structure is parallel to the plane where the mounting opening is located, and the size of each layer of area is the same as that of the mounting opening.
Preferably, the cathode plate 230 and the anode plate 220 are carbon electrode plates or platinum electrode plates, and carbon electrodes with platinum plating on the surfaces are generally used. The edges of the anode plate 220 and the cathode plate 230 are provided with a terminal, namely an anode plate terminal 221 and a cathode plate terminal 231, respectively, for connecting the positive and negative poles of a power supply respectively. The power supply provides electrons to the cathode plate 230 while the anode plate 220 provides electrons to the power supply anode. The anode plate 220 is configured to electrolyze water vapor, producing protons and oxygen. The proton exchange membrane 210 is configured to transport protons from the anode plate 220 side to the cathode plate 230 side. The cathode plate 230 is configured to generate water by reacting protons and oxygen. Wherein, the chemical reaction formula of anode plate and negative plate is respectively:
an anode plate: 2H2O→O2+4H++4e-
A negative plate: o is2+4H++4e-→2H2O
Specifically, the anode of the power source charges the anode plate 220, and the water vapor inside the storage container 100 is electrolyzed at one side of the anode plate 220 to generate hydrogen ions and oxygen, thereby consuming the moisture inside the storage space, and the hydrogen ions enter the proton exchange membrane 210 and move toward the cathode plate 230. The cathode of the power supply charges the cathode plate 230 and provides electrons to the cathode plate 230, and water is generated on one side of the cathode plate 230 by the reaction of the hydrogen ions provided by the proton exchange membrane 210 and the oxygen outside the storage space. In the present embodiment, the centers of the anode plate 220 and the cathode plate 230 are both opened with rectangular openings for allowing the external air to flow to the pem. The openings directly expose part of the proton exchange membrane 210 to the air, increase the contact area between the membrane and the air, and improve the reaction rate of the dehumidification assembly 200, thereby improving the performance of the whole assembly.
The proton exchange membrane 210 includes: a proton-conducting polymer, a porous membrane, and at least one active ingredient. At least one active ingredient is dispersed in the proton-conducting polymer, and the proton-conducting polymer is absorbed into and fills the pores of the porous film. The proton exchange membrane 210 serves to allow hydrogen ions to pass through, so that hydrogen ions generated by the reaction of the anode plate 220 are transported to the cathode plate 230 for reaction of the 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 dehumidification 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, and the material of the diffusion layer 270 is a titanium mesh with a platinum-plated surface, which is used for facilitating electric conduction and allowing water vapor to diffuse. At least one gasket 260 may be positioned between the above-described multi-layered structures, and each gasket 260 is a thin rectangular ring having the same size as the cathode plate 230 and the anode plate 220. Each gasket 260 is made of an elastic insulating material to buffer the pressing force between adjacent layers, and simultaneously prevent other components of the electrolytic dehumidification assembly 200 from being electrified to affect the normal operation of the cathode and anode plates.
In this embodiment, the electrolytic dehumidification assembly 200 may further include: 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. The middle portion of each elastic plate 240 is hollowed out to allow air to pass through.
The electrolytic dehumidification assembly 200 further comprises: two fixing plates 290. The two fixing plates 290 are disposed at the outer sides of the two elastic plates 240 for integrally fixing the elastic plates 240, the anode plate 220, the proton exchange membrane 210 and the cathode plate 230. As shown in fig. 5, a middle portion of each fixing plate 290 is hollowed out to allow gas to pass therethrough. The hollowed-out portion is further provided with a cross-shaped bracket for improving the stability of the fixing plate 290. In this embodiment, the fixing plate 290 is made of a metal material, and further clamps the anode plate 220, the proton exchange membrane 210 and the cathode plate 230, so as to ensure the surface of the proton exchange membrane 210 to be flat, and improve the performance of the electrolytic dehumidification assembly 200.
The electrolytic dehumidification assembly 200 further comprises: a first fan 251 and a second fan 252. The first fan 251 and the second fan 252 may be micro axial fans.
The first fan 251 is disposed on a side of the cathode plate 230 opposite to the proton exchange membrane 210, that is, the first fan 251 is disposed outside the storage space, and an axis of a fan rotating shaft thereof is perpendicular to the cathode plate 230. The first fan 251 blows air outside the storage space toward the proton exchange membrane 210 to increase the air circulation speed near the cathode plate 230. Since oxygen is consumed for the reaction at the cathode plate 230 side, the oxygen concentration near the cathode plate 230 is low. When the electrolytic dehumidification assembly 200 is turned on, the first blower 251 is turned on to blow air toward the cathode plate 230, so as to increase the air circulation rate near the cathode plate 230 and continuously supply oxygen to the cathode plate 230, thereby ensuring that the reaction can be performed rapidly and stably.
