Referring to fig. 1, fig. 1 is a schematic view of a refrigerator according to an embodiment of the present invention. The present invention first provides a refrigerator 1, and the refrigerator 1 may generally include a cabinet 10 and a door 20.
The cabinet 10 may include a housing located at the outermost side of the overall refrigerator 1 to protect the overall refrigerator 1, and a plurality of inner containers. The plurality of inner containers are wrapped by the shell, and a space between the inner containers and the shell is filled with a heat insulation material (forming a foaming layer) so as to reduce outward heat dissipation of the inner containers. Each liner may define a forwardly open compartment, and the compartments may be configured as a refrigerated compartment, a freezer compartment, a temperature change compartment, etc., with the number and function of the particular compartments being configurable according to the needs in advance.
The door 20 is movably installed in front of the inner container to open and close the storage compartment of the inner container, for example, the door 20 may be hinged to one side of the front of the case 10 to open and close the storage compartment in a pivoting manner.
The refrigerator 1 may further include a drawer assembly 30, and the drawer assembly 30 may further include a drawer body drawably provided in the cabinet 10 for a user to take out articles.
Referring to fig. 2, fig. 2 is a schematic block diagram of a refrigerator 1 according to an embodiment of the present invention. In some embodiments, the refrigerator 1 may further include an electrolytic oxygen removing device 40, and the electrolytic oxygen removing device 40 may be disposed in the inner container or the drawer assembly 30 to separate oxygen in air flowing therethrough through an electrolytic reaction and to leave nitrogen in a storage compartment of the inner container or the drawer body, thereby achieving fresh-keeping storage of food.
Specifically, the electrolytic oxygen removing device 40 may be disposed at a rear wall, a side wall, a top wall, a bottom wall, etc. of the storage compartment, and likewise the electrolytic oxygen removing device 40 may be disposed at a rear wall, a side wall, a bottom wall, etc. of the drawer body. In short, after knowing the technical solution of the present embodiment, the person skilled in the art may set the electrolytic oxygen removing device 40 according to the actual situation, which is not listed here.
Referring to fig. 2 to 6, fig. 2 is a schematic view of an electrolytic oxygen removing device 40 of a refrigerator 1 according to an embodiment of the present invention, fig. 3 is an exploded view of the electrolytic oxygen removing device 40 of the refrigerator 1 according to an embodiment of the present invention, fig. 4 is a front view of the electrolytic oxygen removing device 40 of the refrigerator 1 according to an embodiment of the present invention, fig. 5 is a schematic sectional view taken along a section line A-A in fig. 4, and fig. 6 is a schematic sectional view taken along a section line B-B in fig. 4.
In some embodiments, the electrolytic oxygen removal device 40 may further include a reactor 100 and at least one electrolytic oxygen removal unit 200. One side of the reactor 100 forms at least one reaction space 110 which is opened forward, and the electrolytic oxygen removing units 200 are assembled in one-to-one correspondence to the reaction space 110 and are used for consuming oxygen outside the electrolytic oxygen removing device 40 through electrochemical reaction under the action of electrolytic voltage; wherein each of the electrolytic oxygen removing units 200 further includes an anode plate 210, the anode plate 210 having a body plate 212, the body plate 212 being fixed to the rear wall 110a of the reaction space 110.
The reactor 100 may be flat with a wide, inwardly facing recess forming one or more reaction spaces 110, which reaction spaces 110 may be used to hold electrolyte (e.g., sodium hydroxide solution, etc.) for electrolytic reactions.
Referring to fig. 3, in some further embodiments, each electrolytic oxygen removal unit 200 may further include a cathode membrane assembly 220, and the cathode membrane assembly 220 is disposed at an opening of the reaction space 110 spaced apart from the body plate 212 to close the reaction space 110.
The cathode membrane assembly 220 serves to consume oxygen through an electrochemical reaction under the action of an electrolytic voltage. Anode plate 210 is used to provide reactants (e.g., electrons) and generate oxygen to cathode membrane assembly 220 by electrochemical reaction under an electrolytic voltage.
When energized, oxygen in the air may undergo a reduction reaction at cathode membrane assembly 220, namely: o (O) 2 +2H 2 O+4e - →4OH - . The OH "generated by the cathode membrane assembly 220 may undergo an oxidation reaction at the anode plate 210 and generate oxygen, namely: 4OH - →O 2 +2H 2 O+4e - 。
Furthermore, the inventors realized that: a certain interval needs to be firmly maintained between the cathode membrane assembly 220 and the main body plate 212 of the anode plate 210, so as to avoid low reaction efficiency caused by overlarge interval, and avoid that oxygen generated by the anode plate 210 cannot be discharged in time due to overlarge interval, thereby influencing the reaction process.
In the present embodiment, since the body plate 212 of the anode plate 210 is directly fixed to the rear wall 110a of the reaction space 110, that is, the position of the body plate 212 of the anode plate 210 with respect to the entire reaction space 110 is in a stable state, and when the cathode membrane assembly 220 is installed at the opening of the reaction space 110, the space therebetween forms a stable space, and parts for installing the anode plate 210 in the reaction space 110 are omitted in this way, the reaction space 110 is expanded, and the assembly process is simplified.
Referring to fig. 5 and 6, in some embodiments, the anode plate 210 may also be integrally injection-molded with the reactor 100, so that the body plate 212 of the anode plate 210 is firmly fixed to the rear wall 110a of the reaction space 110 and the production efficiency is improved.
Specifically, a clamping wall 112 extending in the circumferential direction thereof is formed in the reaction space 110, and the clamping wall 112 is used to clamp an edge of the body plate 212 in cooperation with the rear wall 110a of the reaction space 110 to fix the body plate 212 such that a middle portion of the body plate 212 is exposed to the reaction space 110.
In injection molding, an injection mold is first manufactured according to the shape of the reactor 100, then the anode plate 210 is fixed at the position of the rear wall 110a of the reactor 100, finally a liquid plastic raw material (such as polypropylene) is injected into the injection mold, and after cooling and shaping, the assembly formed by the anode plate 210 and the reactor 100 is ejected out after opening the mold.
It should be noted that, in designing the injection mold, it is also considered to design the clamping wall 112 at the rear wall 110a of the reaction space 110 so that the final molded reactor 100 can be firmly wrapped around the body plate 212 by using the clamping wall 112.
Further, the grip wall 112 extends along a circumferential direction within the reaction space 110, that is, the grip wall 112 may extend along the rear wall 110a of the reaction space 110. In some specific embodiments, the width of the clamping wall 112 may also be set to between 3cm and 15cm, such as 3cm, 10cm, 15cm, etc.
By the above definition, not only the clamping wall 112 can be matched with the rear wall 110a of the reactor 100 to fix the main body plate 212 of the anode plate 210, but also the clamping wall 112 does not occupy an excessive area of the main body plate 212, so that the exposed main body plate 212 is larger to ensure the electrolytic efficiency.
Referring to fig. 3, 5 and 6, further, the anode plate 210 may further include an anode tab 214, the anode tab 214 being formed at a top edge of the body plate 212 and protruding from the reaction space 110 for connection to an external power source.
Specifically, the main body plate 212 of the anode plate 210 may be integrally formed with an anode tab 214, and the anode tab 214 is formed on top of the main body plate 212, which is connected to the positive electrode of the external power source after protruding from the reaction space 110 of the reactor 100, so that the anode plate 210 is positively charged, and thus oxidation reaction occurs.
Since the main body plate 212 of the anode plate 210 is wrapped at the rear wall 110a of the reaction space 110 and the anode tab 214 is formed at the top edge of the main body plate 212, a part of the anode tab 214 may be injection-molded into the reactor 100 during injection molding, so that only the end thereof leaks out of the reactor 100. Thus, the anode plate 210 can be conveniently electrified, and the anode connecting piece 214 can be ensured to be in a stable state, so that the normal power supply of the anode plate 210 is prevented from being influenced by factors such as shaking.
Referring to fig. 7, fig. 7 is a schematic view of an anode plate 210 in an electrolytic oxygen removal device 40 according to one embodiment of the present invention. Further, the anode tab 214 may further include a first section 214a and a second section 214b, the first end of the first section 214a being formed at the top edge of the body plate 212 and extending upward to the interior of the reactor 100, and the first end of the second section 214b being formed at the second end of the first section 214a and extending forward such that the second end thereof protrudes from the interior of the reactor 100.
Referring to fig. 5, the anode tab 214 is formed at the top edge of the body plate 212 and then extends upward until reaching the inside of the reactor 100, and then extends forward from the inside of the reactor 100. This approach takes full advantage of injection molding over the solution of directly exiting from the clamping wall 112, where the anode tab 214 is secured by the thicker reactor 100 (the first section 214a penetrating upward into the interior of the reactor 100), ensuring that the anode tab 214 is more firmly secured.
Referring to fig. 5 and 7, further, the first section 214a and/or the second section 214b of the anode tab 214 may also be wavy, and fig. 5 illustrates that the first section 214a is wavy. This facilitates a larger contact area between the anode tab 214 and the reactor 100 during injection molding, further ensuring that the anode tab 214 is more firmly secured.
In summary, the electrolytic oxygen removing device 40 of the present embodiment provides a solution for fixing the reactor 100 and the anode plate 210 by integral injection molding. In this embodiment, the main plate 212 of the anode plate 210 is clamped together by the clamping wall 112 and the rear wall 110a of the reaction space 110 by injection molding, and the anode tab 214 of the anode plate 210 is also fixed to the reactor 100 together.
The electrolytic oxygen removing device 40 adopting the mode not only can be convenient for fixing the anode plate 210 and the reactor 100 and cancel other parts for fixing the anode plate 210, but also simplifies the production process, improves the production efficiency and is convenient for batch production.

In addition, when the fixing is performed by thermal welding, the first and second connection ribs 116 and 226 may also serve as welding points, so that the fixing frame 222 and the reactor 100 are not deformed as a whole, and the gap tightness after welding is good.
Further, the cathode membrane set 224 further includes a catalytic layer, a first waterproof and breathable layer, a conductive layer, and a second waterproof and breathable layer, which are sequentially disposed. The catalytic layer may employ a noble or rare metal catalyst, such as metallic platinum, metallic gold, metallic silver, metallic manganese, or metallic rubidium, among others. The first waterproof and breathable layer and the second waterproof and breathable layer may be waterproof and breathable films such that the electrolyte cannot leak out of the reaction space 110, and air may enter the reaction space 110 through the first waterproof and breathable layer and the second waterproof and breathable layer. The conductive layer can be made into corrosion-resistant metal current collecting net, such as metal nickel, metal titanium and the like, so that the conductive layer not only has better conductivity, corrosion resistance and supporting strength.
