[0033] Referring to Figure 1 , Figure 1 is a schematic diagram of a refrigerator according to an embodiment of the present application. The present application first provides a refrigerator 1, which can generally include a cabinet 10 and a door body 20.

[0034] The cabinet 10 can include an outer shell located at the outermost side of the overall refrigerator 1 to protect the entire refrigerator 1, and a plurality of inner tanks wrapped by the outer shell and filled with a heat preservation material (forming a foaming layer) in the space between the outer shell and the inner tank to reduce heat dissipation of the inner tank to the outside. Each inner tank can define a storage compartment open to the front, and the storage compartment can be configured as a refrigeration compartment, a freezing compartment, a variable temperature compartment, and the like, and the number and function of the specific storage compartment can be configured according to the pre-requisite demand.

[0035] The door body 20 is movably provided in front of the inner tank to open and close the storage compartment of the inner tank, for example, the door body 20 can be provided on one side of the front part of the cabinet 10 by a hinged manner, and open and close the storage compartment by a pivoting manner.

[0036] The refrigerator 1 can further include a drawer assembly 30, and the drawer assembly 30 can further include a drawer body which is pullably provided in the cabinet 10 so as to allow a user to take out an article.

[0037] Referring to Figure 2 , Figure 2 is a schematic block diagram of a refrigerator 1 according to an embodiment of the present application. In some embodiments, the refrigerator 1 can further include an electrolytic oxygen removal device 40 which can be provided in the inner tank or the drawer assembly 30 to separate oxygen in the air flowing therethrough by an electrolytic reaction and leave nitrogen in the storage compartment of the inner tank or the drawer body, so as to achieve fresh-keeping storage of food.

[0038] Specifically, the electrolytic oxygen removal device 40 can be provided on the rear wall, the side wall, the top wall, the bottom wall, and the like of the storage compartment, and likewise, the electrolytic oxygen removal device 40 can also be provided on the rear wall, the side wall, the bottom wall, and the like of the drawer body. In summary, those skilled in the art can set the electrolytic oxygen removal device 40 according to the actual situation after knowing the technical solution of the present embodiment, which is not listed one by one here.

[0039] Referring to Figures 2 to 6 , Figure 2 is a schematic view of an electrolytic oxygen removal device 40 of a refrigerator 1 according to an embodiment of the present application, Figure 3 is an exploded view of the electrolytic oxygen removal device 40 of the refrigerator 1 according to an embodiment of the present application, Figure 4 is a front view of the electrolytic oxygen removal device 40 of the refrigerator 1 according to an embodiment of the present application, Figure 5 is a schematic cross-sectional view taken along the sectioning line A-A in Figure 4 , Figure 6 is a schematic cross-sectional view taken along the sectioning line B-B in Figure 4 .

[0040] In some embodiments, the electrolytic oxygen removal device 40 can further include a reactor 100 and at least one electrolytic oxygen removal unit 200. The reactor 100 has one side forming at least one reaction space 110 open to the front, and the electrolytic oxygen removal units 200 are correspondingly arranged in the reaction space 110 for consuming oxygen outside the electrolytic oxygen removal device 40 through an electrochemical reaction under the action of an electrolytic voltage; wherein each electrolytic oxygen removal unit 200 further includes an anode plate 210 having a main plate 212 fixed to a rear wall 110a of the reaction space 110.

[0041] The reactor 100 can be flat, and the wider side is inwardly recessed to form one or more reaction spaces 110, which can be used to hold electrolyte (such as sodium hydroxide solution, etc.) for electrolytic reaction.

[0042] Referring to Figure 3 , in some further embodiments, each electrolytic oxygen removal unit 200 can further include a cathode membrane assembly 220 arranged in the open part of the reaction space 110 spaced apart from the main plate 212 to close the reaction space 110.

[0043] The cathode membrane assembly 220 is used to consume oxygen through an electrochemical reaction under the action of an electrolytic voltage. The anode plate 210 is used to provide a reactant (such as electrons) to the cathode membrane assembly 220 through an electrochemical reaction under the action of an electrolytic voltage and generate oxygen.

[0044] Under the condition of power-on, oxygen in the air can undergo a reduction reaction at the cathode membrane assembly 220, i.e. O2+2H2O+4e - →4OH - . The OH- generated by the cathode membrane assembly 220 can undergo an oxidation reaction at the anode plate 210 and generate oxygen, i.e. 4OH - →O2+2H2O+4e-.

[0045] In addition, the inventors realized that a certain distance needs to be stably maintained between the cathode membrane assembly 220 and the main plate 212 of the anode plate 210 to avoid low reaction efficiency due to too large distance, and to avoid oxygen generated by the anode plate 210 being unable to be timely discharged due to too small distance, thereby affecting the reaction progress.

[0046] In the present embodiment, since the main 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 main plate 212 of the anode plate 210 relative to the whole 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 distance between the two forms a stable distance, and this way also omits the parts for installing the anode plate 210 in the reaction space 110, expands the reaction space 110, and simplifies the assembly process.

[0047] Referring to Figure 5 and Figure 6 In some embodiments, the anode plate 210 can also be formed in an integral injection molding manner with the reactor 100, so that the main plate 212 of the anode plate 210 is stably fixed to the rear wall 110a of the reaction space 110, and the production efficiency is improved.

[0048] Specifically, the reaction space 110 is formed with a clamping wall 112 extending along the circumference thereof, and the clamping wall 112 is used to clamp the edge of the main plate 212 in cooperation with the rear wall 110a of the reaction space 110 to fix the main plate 212, so that the middle part of the main plate 212 is exposed to the reaction space 110.

[0049] When injection molding, first, an injection molding mold is 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, and finally liquid plastic raw materials (such as polypropylene, etc.) are injected into the injection molding mold, and after cooling and setting, the assembly of the anode plate 210 and the reactor 100 is ejected from the mold.

[0050] It should be noted that when designing the injection molding mold, the clamping wall 112 is also designed at the rear wall 110a of the reaction space 110, so that the finally formed reactor 100 can be stably wrapped around the main plate 212 by using the clamping wall 112.

[0051] In addition, the clamping wall 112 extends along the circumference in the reaction space 110, that is, the clamping wall 112 can extend along the rear wall 110a of the reaction space 110. In some specific embodiments, the width of the clamping wall 112 can also be set to be between 3 cm and 15 cm, such as 3 cm, 10 cm, 15 cm, etc.

[0052] By the above-mentioned limitation, not only the clamping wall 112 can fix the main plate 212 of the anode plate 210 in cooperation with the back wall 110a of the reactor 100, but also the clamping wall 112 does not occupy too much area of the main plate 212, and further, the exposed main plate 212 is larger to ensure the electrolysis efficiency.

[0053] Referring to Figure 3 , Figure 5 and Figure 6 , further, the anode plate 210 can further include an anode contact tab 214 formed at the top edge of the main plate 212 and extending out of the reaction space 110 to facilitate connection with an external power source.

[0054] Specifically, the main plate 212 of the anode plate 210 can be integrally formed with the anode contact tab 214 formed at the top of the main plate 212, which extends out of the reaction space 110 of the reactor 100 to be connected with the positive pole of the external power source, so that the anode plate 210 is positively charged to further cause the oxidation reaction.

[0055] Since the main plate 212 of the anode plate 210 is wrapped at the back wall 110a of the reaction space 110, and the anode contact tab 214 is formed at the top edge of the main plate 212, when injection molding, part of the section of the anode contact tab 214 can also be injection molded in the reactor 100, and only the end of the anode contact tab 214 can be exposed out of the reactor 100. In this way, not only the power supply for the anode plate 210 can be facilitated, but also the anode contact tab 214 can be ensured to be in a stable state, avoiding the influence of the normal power supply of the anode plate 210 due to the shaking of the anode contact tab 214.

[0056] Referring to Figure 7 , Figure 7 is a schematic view of the anode plate 210 in the electrolysis deoxidizing device 40 according to an embodiment of the present application. Further, the anode contact tab 214 can further include a first section 214a and a second section 214b, the first end of the first section 214a is formed at the top edge of the main plate 212 and extends upward to the inside of the reactor 100, and the first end of the second section 214b is formed at the second end of the first section 214a and extends forward, so that the second end of the second section 214b extends out of the inside of the reactor 100.

[0057] In combination Figure 5 , the anode contact tab 214 is formed at the top edge of the main plate 212 and first extends upward to the inside of the reactor 100, and then extends forward out of the inside of the reactor 100. Compared with the scheme of directly penetrating out of the clamping wall 112, this way makes full use of the advantage of injection molding, and the reactor 100 with a larger thickness (the first section 214a penetrates into the inside of the reactor 100 upward) is used to fix the anode contact tab 214, so that the anode contact tab 214 is more stably fixed.

[0058] Referring to Figure 5 and Figure 7 Further, the first section 214a and / or the second section 214b of the anode tab 214 can also be wavy, Figure 5 It is shown that the first section 214a is wavy. This is advantageous for obtaining 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 fixed.

[0059] In summary, the electrolysis oxygen removal device 40 of the present embodiment provides a technical solution for fixing the reactor 100 and the anode plate 210 by means of one-piece injection molding. In the present embodiment, the main plate 212 of the anode plate 210 is clamped by the clamping wall 112 and the rear wall 110a of the reaction space 110 by means of injection molding, and the anode tab 214 of the anode plate 210 is also fixed to the reactor 100.

[0060] The electrolysis oxygen removal device 40 in this way not only facilitates the fixing of the anode plate 210 and the reactor 100, eliminates other parts for fixing the anode plate 210, but also simplifies the production process, improves production efficiency, and facilitates mass production.

[0061] Referring to Figures 8 to 10 , Figure 8 is a front view of an electrolysis oxygen removal device 40 of a refrigerator according to another embodiment of the present application, Figure 9 is a schematic cross-sectional view taken along the sectioning line C-C in Figure 8 , Figure 10 is a schematic cross-sectional view taken along the sectioning line D-D in Figure 8 .

[0062] In other embodiments, the anode plate 210 can also be fixed to the rear wall 110a of the reaction space 110 by other means, such as adhesion, heat welding, etc.

[0063] That is, in the present embodiment, the anode plate 210 and the reactor 100 can be made separately first, and then fixed to the rear wall 110a of the reactor 100 by other means. Since the anode plate 210 is ultimately fixed to the rear wall 110a of the reactor 100, this way also enables the anode plate 210 and the cathode membrane assembly 220 to maintain a stable spacing.

[0064] Specifically, when assembling the anode plate 210 and the reactor 100, the anode plate 210 can enter the reaction space 110 from the front to the rear through the opening of the reaction space 110, and then be fixed to the rear wall 110a of the reaction space 110 by means of adhesion, heat welding, etc.

[0065] Referring toFigure 11 , Figure 11 is a schematic view of the reactor 100 in the electrolytic oxygen-removing device 40 according to another embodiment of the present application. Further, the reactor 100 is provided with a groove 114 open forward at the top of the reaction space 110, which is used to avoid the anode contact piece 214 when the main plate 212 is fixed to the rear wall 110a from front to back, so that the anode contact piece 214 extends out of the reaction space 110.

[0066] In this embodiment, the groove 114 is open forward, and when the anode plate 210 is installed in the reaction space 110 from front to back, the main plate 212 is attached to the rear wall 110a of the reaction space 110, while the anode contact piece 214 of the anode plate 210 enters the groove 114, so that when the cathode membrane assembly 220 is installed at the opening of the reaction space 110, it does not interfere with the anode contact piece 214 extending out of the reaction space 110.

[0067] Referring to Figure 3 , in some embodiments, each cathode membrane assembly 220 can further include a fixed frame 222 and a cathode membrane group 224. The fixed frame 222 is fixed to the opening of the reaction space 110, and the central part thereof is a hollow area, and the inner side of the fixed frame 222 is provided with an installation groove 227 in the circumferential direction. The peripheral edge of the cathode membrane group 224 is fixed in the installation groove 227, so that it is fixed to the center of the fixed frame 222.

[0068] The shape of the fixed frame 222 matches the opening of the reaction space 110, and it can be fixed to the reactor 100 by heat welding. The inner side of the fixed frame 222 is provided with an installation groove 227 in the circumferential direction, and the peripheral edge of the cathode membrane group 224 is fixed in the installation groove 227, so that the cathode membrane group 224 is tightly fixed to the center of the fixed frame 222, to stably provide a front wall for the reaction space 110.

[0069] Referring to Figure 5 , Figure 6 , Figure 9 and Figure 10 , in particular, the reactor 100 is formed with a first connecting rib 116 at the opening of the reaction space 110, and the side of the fixed frame 222 facing the reaction space 110 is formed with a second connecting rib 226 opposite to the connecting rib, to seal the reaction space 110.

[0070] In addition, when fixed by heat welding, the first connecting rib 116 and the second connecting rib 226 can also serve as welding points, so that the overall deformation of the fixed frame 222 and the reactor 100 can be ensured, and the gap sealing performance is good after welding.

[0071] Further, the cathode film assembly 224 further comprises a catalytic layer, a first waterproof and air-permeable layer, a conductive layer and a second waterproof and air-permeable layer arranged in sequence. The catalytic layer can be made of a noble metal or a rare metal catalyst, such as platinum, gold, silver, manganese or rubidium. The first waterproof and air-permeable layer and the second waterproof and air-permeable layer can be waterproof and air-permeable films, so that the electrolyte cannot seep out of the reaction space 110, and air can pass through the first waterproof and air-permeable layer and the second waterproof and air-permeable layer into the reaction space 110. The conductive layer can be made of a corrosion-resistant metal current collector, such as nickel or titanium, so as to have better conductivity, corrosion resistance and support strength.

[0072] Referring to Figure 3 Further, the top of the fixed frame 222 further has an extension 228, and the cathode film assembly 220 further comprises a cathode tab 229, one end of the cathode tab 229 being fixed to the top of the conductive layer of the cathode film assembly 224 and extending through the extension 228 to protrude out of the fixed frame 222, so as to be connected to the negative electrode of an external power supply.

[0073] Referring to Figure 3 and Figure 11 In some embodiments, a plurality of reaction spaces 110 can be arranged on the reactor 100, and a partition beam 117 can be arranged between adjacent two reactors 100. The reactor 100 can further define a liquid storage space 119 for storing electrolyte, the liquid storage space 119 can be located on one side of all the reaction spaces 110, and each partition beam 117 can further be provided with a flow passage 117a. The electrolyte in the liquid storage space 119 can first be supplied to the reaction space 110 adjacent to the liquid storage space 119, and then be supplied to the remaining reaction spaces 110 in sequence through the flow passages 117a.

[0074] Referring to Figure 3 , Figure 6 , Figure 10 and Figure 11 In some embodiments, the reactor 100 can further be provided with an oxygen exhaust channel 118 for each reaction space 110. Each oxygen exhaust channel 118 has an oxygen inlet 118a and an oxygen outlet 118b. The oxygen inlet 118a is used to connect the oxygen exhaust channel 118 with the reaction space 110, and the oxygen outlet 118b is used to exhaust the gas in the oxygen exhaust channel 118.

[0075] Referring to Figure 3 and Figure 11Further, the top of the reactor 100 can be further provided with a liquid storage tank 115, which is in communication with the liquid storage space 119, and the oxygen outlet 118b of the oxygen outlet channel 118 can be arranged at the bottom of the liquid storage tank, so that the liquid in the liquid storage tank 115 can not only seal the oxygen outlet channel 118 to prevent external air from entering the reaction space 110 through the oxygen outlet channel 118, but also can collect and filter the gas generated by each electrolytic oxygen removal unit 200, and when the gas needs to be used, only one gas guide pipe is needed to be connected to the external environment, which is simple in structure and easy to realize.

[0076] It will thus be appreciated that those skilled in the art will be able to devise numerous other arrangements without departing from the scope of the present application as defined by the appended claims, wherein like reference numerals are used to denote like components throughout the several views.
