In the field of refrigerators, by setting up a deoxygenation component and using its electrochemical reaction to consume internal oxygen to create a low-oxygen atmosphere, the preservation effect can be improved. The electrochemical reaction of the deoxygenation component consists of two half reactions, which are carried out on the cathode plate and the anode plate respectively. The reactants of the cathode plate include oxygen, and the reactants of the anode plate include water. The occurrence of electrochemical reactions requires continuous replenishment of reactants. During the deoxygenation process, if the anode plate cannot be replenished with enough water, the electrochemical reaction rate will be low, resulting in low efficiency of electrolytic deoxygenation.

[0034] Figure 1 1 is a schematic diagram of a refrigerator 10 according to an embodiment of the present invention, wherein arrows in the figure indicate airflow directions. In this embodiment, the refrigerator 10 may be an air-cooled refrigerator 10, and air circulation is used inside the air-cooled refrigerator 10 to cool the storage compartment 111.

[0035] Figure 2 yes Figure 1 The schematic diagram of the storage container 200 and the air duct cover 130 in the refrigerator 10 is shown. Figure 3 is a schematic diagram of a storage device 150 in a refrigerator 10 according to an embodiment of the present invention, Figure 4 yes Figure 3 The exploded view of the storage device 150 in the refrigerator 10 is shown. Figure 5 yes Figure 4 A further exploded view of the storage device 150 in the refrigerator 10 is shown.

[0036] The refrigerator 10 may generally include an inner tank 110, a storage container 200, a deoxidizing assembly 400, and an air induction assembly 300, and may also include an evaporator 120, an air supply fan 140, an air duct cover plate 130, a moisture permeable membrane 500, and a cover plate 600. In this embodiment, the storage container 200, the moisture permeable membrane 500, the deoxidizing assembly 400, the air induction assembly 300, and the cover plate 600 may be integrated to form a storage device 150.

[0037] The inner tank 110 has a storage compartment 111 formed therein, and an air supply duct 112 and an evaporator cavity located at the rear side of the storage compartment 111. The air supply duct 112 is provided with a return air port 132. In the present embodiment, there may be one storage compartment 111, which is a refrigerated compartment. In other optional embodiments, there may be multiple storage compartments 111, which include a refrigerated compartment and a frozen compartment. The air supply duct 112 is connected to the storage compartment 111 through the air supply port 131 and the return air port 132. The air supply flow after heat exchange with the evaporator 120 enters the storage compartment 111 from the air supply port 131, flows through the interior of the storage compartment 111, and then merges into the return air port 132. The flow channel of the air supply flow forms the air supply duct 112.

[0038] The air duct cover 130 is disposed on the front side of the back wall of the inner liner 110 to define an air supply duct 112 between the air duct cover 130 and the back wall of the inner liner 110 . The air return port 132 is located on the air duct cover 130 and at the bottom of the air duct cover 130 .

[0039] The storage container 200 is disposed in the storage compartment 111, and preferably, can be disposed at the bottom of the refrigeration compartment. The storage container 200 can be a drawer, and a storage space is formed inside the drawer, and the drawer includes a cylinder 210 with a forward opening and a drawer body 220 that can be pulled out and disposed in the cylinder 210. The back wall of the storage container 200 is close to the air duct cover plate 130.

[0040] Figure 6 yes Figure 5 The schematic diagram of the cylinder 210 of the storage container 200 of the storage device 150 in the refrigerator 10 is shown. Figure 7 This is a partial enlarged view of point A in Figure 6. Figure 8 yes Figure 5 Another schematic diagram of the cylinder 210 of the storage container 200 of the storage device 150 in the refrigerator 10 is shown.

[0041] The top surface of the storage container 200 is provided with a ventilated area 230 and an air induction area 240. The ventilated area 230 is located in the middle of the top surface, and the air induction area 240 is arranged behind the ventilated area 230. In this embodiment, the top surface of the storage container 200 may be rectangular in shape, and the ventilated area 230 may also be rectangular in shape, so that the gas in the storage container 200 can escape from the ventilated area 230.

[0042] The permeable area 230 includes a deoxygenation area 231 and a dewatering area 235. The deoxygenation area 231 is located in the middle of the permeable area 230, and the deoxygenation area 231 is recessed into the storage container 200 to form a deoxygenation chamber 232; in this embodiment, the deoxygenation chamber 232 can accommodate the deoxygenation component 400. A deoxygenation port is provided at the bottom of the deoxygenation chamber 232, and the deoxygenation port is configured to allow the gas inside the storage container 200 to pass through; the periphery of the deoxygenation port extends toward the side wall of the deoxygenation chamber 232 to form a support platform, and the support platform limits the deoxygenation component 400 to the bottom of the deoxygenation chamber 232, that is, the support platform is used to receive the deoxygenation component 400. The dewatering area 235 is arranged near the deoxygenation area 231 and is located on both sides of the deoxygenation area 231; the dewatering area 235 is provided with through holes arranged in an array, and the gas in the storage container 200 can escape from the through holes. The outer periphery of the dewatering area 235 extends upward in the direction facing away from the storage container 200 to form a dewatering chamber 237, and an opening 239 leading to the deoxygenation area 231 is provided on the dewatering chamber 237; in this embodiment, the dewatering chamber 237 can accommodate a moisture permeable membrane 500, and there are two dewatering areas 235 and two dewatering chambers 237. A clamping portion 238 is also provided on the outer wall of the dewatering chamber 237 facing the deoxygenation area 231, which is used to clamp with the deoxygenation assembly 400 to fix the deoxygenation assembly 400. The dewatering chamber 237 can be integrally formed with the storage container 200, or can be fixed together by gluing, screwing or other suitable methods.

[0043] Since the oxygen density is relatively large and concentrated at the bottom of the storage container 200, and the oxygen concentration far from the bottom is relatively small, the deoxygenation zone 231 is set to be recessed into the storage container 200, which can promote the deoxygenation component 400 to fully contact the oxygen in the storage container 200 and increase the rate of the electrochemical reaction.

[0044] Setting the dewatering zone 235 close to the deoxygenation zone 231 can make the moisture permeable membrane 500 close to the oxygen-consuming part 420 of the deoxygenation component 400, thereby enabling the water vapor generated by the electrochemical reaction of the oxygen-consuming part 420 to quickly seep out through the moisture permeable membrane 500, thereby reducing or avoiding the water vapor generated by the oxygen-consuming part 420 from being retained inside the storage container 200, which is beneficial for maintaining the humidity inside the storage container 200 within a suitable range.

[0045] Since the dewatering chamber 237 is provided with an opening 239 leading to the deoxidation zone 231 , the water vapor seeping through the moisture permeable membrane 500 can also flow from the opening 239 to the electrolysis section 410 of the deoxidation assembly 400 , thereby becoming a reactant for the electrochemical reaction of the electrolysis section 410 , thereby replenishing the water source for the electrolysis section 410 .

[0046] The air induction area 240 has one end adjacent to the air permeable area 230 and the other end adjacent to the return air port 132. The air induction area 240 extends obliquely upward from the upper back wall of the storage container 200 to the outer edge of the deoxidation zone 231. In this embodiment, the air induction area 240 may be located in the channel between the return air port 132 and the deoxidation zone 231; the air induction area 240 is inclined so that part of the return air flow near the return air port 132 flows obliquely upward along the air induction area 240 to the deoxidation zone 231.

[0047] The air induction assembly 300 is disposed above the air induction area 240 , and is configured to guide at least part of the return air flow of the storage compartment 111 to the deoxidation assembly 400 .

[0048] The air induction assembly 300 includes: two air induction plates 310, which are arranged in parallel and spaced apart along the extension direction of the air induction area 240, so that the two air induction plates 310 form an air induction channel 311 above the air induction area 240, and the air induction channel 311 is directly opposite to the deoxidation assembly 400. In this embodiment, the two air induction plates 310 are erected above the air induction area 240, and each air induction plate 310 extends from the portion where the back wall and the top surface of the storage container 200 meet to the outer wall of a dewatering chamber 237, and the distance between the two air induction plates 310 is substantially equal to the distance between the outer walls of the dewatering chamber 237 located on both sides of the deoxidation zone 231, so that the air induction channel 311 leading to the deoxidation zone 231 is formed between the two air induction plates 310 and the air induction area 240. In this embodiment, the air induction assembly 300 can be integrally formed with the storage container 200, or can be fixed above the air induction area 240 in any manner, for example, by screwing, bonding, or snapping.

[0049] The air induction component 300 guides at least part of the return air flow that reaches the vicinity of the return air port 132 to the deoxidation component 400, so that the water vapor in the return air flow can be used as the reactant required for the electrochemical reaction of the deoxidation component 400. Since the return air port 132 is the intersection of the cold and hot air flows, the return air flow carries more water vapor, which can provide more reactants for the deoxidation component 400. The deoxidation efficiency of the deoxidation component 400 can be improved without separately providing a water source or a water delivery device for the deoxidation component 400, thereby simplifying the structure of the refrigerator 10 equipped with the deoxidation component 400 and saving manufacturing costs.

[0050] Since the return air flow can provide the deoxidation component 400 with the water vapor required for the electrochemical reaction, the deoxidation component 400 reduces the water vapor content in the return air flow while deoxidizing the interior of the storage container 200, thereby reducing the amount of frost on the evaporator 120.

[0051] Fig. 9 yes Figure 5 The schematic diagram of the deoxygenation assembly 400 of the storage device 150 in the refrigerator 10 is shown. Fig.10 yes Fig. 9 An exploded view of a deoxygenation assembly 400 of a storage device 150 in a refrigerator 10 is shown.

[0052] The deoxidation assembly 400 is disposed above the air permeable area 230; the deoxidation assembly 400 has an electrolysis part 410 facing away from the inside of the storage container 200 and used to electrolyze water vapor outside the storage container 200 through an electrochemical reaction, and an oxygen consumption part 420 facing the inside of the storage container 200 and used to consume oxygen inside the storage container 200 through an electrochemical reaction. In this embodiment, the deoxidation assembly 400 can be located above the deoxidation zone 231 and located at the above-mentioned deoxidation chamber 232.

[0053] The oxygen consumption unit 420 faces the inside of the storage container 200, and the oxygen in the storage container 200 can contact the oxygen consumption unit 420; the electrolysis unit 410 faces away from the inside of the storage container 200 and is exposed to the outside of the storage container 200. A proton exchange membrane 430 for transporting hydrogen ions can be provided between the oxygen consumption unit 420 and the electrolysis unit 410.

[0054] That is, the deoxidizing component 400 uses the water vapor outside the storage container 200 and the oxygen inside the storage container 200 as reactants to perform an electrochemical reaction to reduce the oxygen content inside the storage container 200. The electrochemical reaction includes two half reactions occurring in the electrolysis part 410 and the oxygen consumption part 420 respectively. The electrolysis part 410 electrolyzes the water vapor outside the storage container 200 under the action of the electrolysis voltage to generate hydrogen ions and oxygen. The proton exchange membrane 430 is configured to transport hydrogen ions from one side of the electrolysis part 410 to the other side of the oxygen consumption part 420. Under the action of the electrolysis voltage, the oxygen consumption part 420 causes the hydrogen ions generated by the electrolysis part 410 to react electrochemically with the oxygen inside the storage container 200 to generate water to consume the oxygen inside the storage container 200, so that a low-oxygen fresh-keeping environment is formed inside the storage container 200.

[0055] The deoxidizing component 400 is correspondingly provided with an inserting portion 441 which is engaged with the above-mentioned engaging portion 238 . The deoxidizing component 400 is engaged with the above-mentioned engaging portion 238 through its inserting portion 441 to achieve fixation.

[0056] By providing mutually engaging clamping parts 238 and plugging parts 441, the deoxidation assembly 400 can be quickly fixed above the deoxidation zone 231. The structure is simple, and the disassembly and assembly steps of the deoxidation assembly 400 are simplified, making it easy to install or replace the deoxidation assembly 400.

[0057] In the present embodiment, the deoxidation assembly 400 may further include a mounting frame 440, a first elastic frame 450 and a second elastic frame 460. The mounting frame 440 is arranged on a side of the oxygen consumption part 420 facing the inside of the storage container 200, and is configured to be clamped with the clamping portion 238. The first elastic frame 450 and the second elastic frame 460 are respectively arranged on a side of the oxygen consumption part 420 facing away from the proton exchange membrane 430, and a side of the electrolysis part 410 facing away from the proton exchange membrane 430, to play a clamping and buffering role. The first elastic frame 450 and the second elastic frame 460 can be made of elastic material to buffer the squeezing force between adjacent layers. The middle parts of the first elastic frame 450, the second elastic frame 460 and the mounting frame 440 are all hollowed out so that the electrolysis part 410 and the oxygen consumption part 420 are in contact with the surrounding air.

[0058] In this embodiment, the installation frame 440 can be rectangular in shape, and the plug-in portion 441 of the deoxidation component 400 is arranged on two opposite side frames of the installation frame 440. The second elastic frame 460, the electrolysis part 410, the proton exchange membrane 430, the oxygen consumption part 420, and the first elastic frame 450 are all arranged in the installation frame 440, thereby forming a deoxidation component 400 with a multi-layer structure. The deoxidation component 400 is composed of the second elastic frame 460, the electrolysis part 410, the proton exchange membrane 430, the oxygen consumption part 420, the first elastic frame 450 and the installation frame 440 from top to bottom. The above-mentioned multi-layer components of the deoxidation component 400 can be fixed in position by any method, for example, by screwing, bonding or clamping.

[0059] In this embodiment, the electrolysis part 410 and the oxygen consumption part 420 of the deoxygenation component 400 can be connected to the control circuit through wires, and the control circuit of the refrigerator 10 provides them with an electrolysis voltage. In other optional embodiments, the electrolysis voltage of the deoxygenation component 400 can also be provided by a battery, and the electrolysis part 410 and the oxygen consumption part 420 are connected to the anode and cathode of the battery respectively, and the deoxygenation component 400 can enter the electrolysis working state. If the user does not need to use the deoxygenation function, the connection circuit can be disconnected.

[0060] In some optional embodiments, the refrigerator 10 may further include: an electrolysis fan, which is disposed in the deoxidation chamber 232 and located above the deoxidation assembly 400, that is, the electrolysis fan may be located on the side of the electrolysis part 410 facing away from the proton exchange membrane 430, and is configured to promote the formation of an airflow blowing toward the electrolysis part 410, so as to guide the airflow entering the deoxidation assembly 400 above through the air induction channel 311 to the electrolysis part 410. The electrolysis fan may be a micro axial flow fan, whose rotating shaft is perpendicular to the electrolysis part 410, and is used to blow the air outside the storage container 200 toward the electrolysis part 410.

[0061] Since the reactant of the electrolysis section 410 is water vapor, the electrolysis section 410 needs to be continuously replenished with water so that the electrolysis reaction can continue. When the deoxidation assembly 400 is turned on, the control circuit supplies power to the oxygen consumption section 420 and the electrolysis section 410 respectively, and the electrolysis fan is turned on at the same time. The electrolysis fan blows air to the electrolysis section 410, and blows water vapor in the air to the electrolysis section 410 to provide reactants to the electrolysis section 410.

[0062] In other optional embodiments, the refrigerator 10 may further include a fan bracket for fixedly supporting the electrolysis fan, wherein the air supply area of ​​the electrolysis fan is directly opposite to the circular opening in the middle of the fan bracket, and can blow the airflow to the electrolysis part 410. The fan bracket can fixedly support the electrolysis fan to prevent the electrolysis fan from shaking during operation, and at the same time, a certain distance can be formed between the electrolysis fan and the electrolysis part 410 to facilitate gas circulation.

[0063] The electrolysis fan is arranged above the electrolysis part 410 of the deoxygenation component 400, which shortens the distance between the electrolysis fan and the deoxygenation component 400 and improves the air supply efficiency of the electrolysis fan. After the electrolysis fan is turned on, it can quickly provide the deoxygenation component 400 with water vapor required for the electrolysis reaction, which is beneficial to improve the electrolysis efficiency of the deoxygenation component 400 and achieve rapid oxygen reduction.

[0064] The side of the fan bracket facing away from the deoxygenation component 400 is used to fix the electrolysis fan, and the side facing the deoxygenation component 400 is screwed and fixed to the second elastic frame 460 of the deoxygenation component 400. The fan bracket has the function of fixing and supporting the electrolysis fan, and also has the function of connecting the deoxygenation component 400. Its dual fixing function integrates the deoxygenation component 400 and the electrolysis fan into one, and makes the electrolysis fan close to the deoxygenation component 400, providing a structural basis for shortening the distance between the electrolysis fan and the deoxygenation component 400.

[0065] Since the deoxygenation component 400 generates water while deoxygenating the storage container 200 during operation, the operation of the deoxygenation component 400 will increase the humidity in the storage container 200. The moisture accumulation inside the storage container 200 will lead to an increase in humidity, and appropriately increasing the humidity is conducive to improving the preservation effect of the storage container 200. However, when the humidity in the storage container 200 is too high, if the deoxygenation component 400 continues to operate without taking measures to dehumidify the storage container 200, condensation and dripping may occur, resulting in a deterioration of the storage environment.

[0066] The moisture permeable film 500 is disposed in the dewatering cavity 237 and is disposed close to the dewatering area 235, and is configured to allow water vapor in the storage container 200 to seep out. The shape of the moisture permeable film 500 is adapted to the shape of the dewatering area 235 to seal the dewatering area 235. The moisture permeable film 500 is configured to allow water vapor in the storage container 200 to slowly permeate and be discharged to the outside of the storage container 200, so that the humidity in the storage container 200 is always maintained within a suitable range, and condensation or dripping is prevented from being generated by excessive moisture in the space.

[0067] A deoxygenation zone 231 and a dewatering zone 235 are set on the top surface of the storage container 200, a deoxygenation component 400 and an electrolytic blower are installed in the deoxygenation chamber 232, and a moisture permeable membrane 500 is installed in the dewatering chamber 237. This can prevent the deoxygenation component 400 and the moisture permeable membrane 500 from occupying too much storage space, thereby improving the use efficiency of the storage container 200.

[0068] In this embodiment, the moisture permeable membrane 500 may be a pervaporation membrane having a hydrophilic layer and a hydrophobic layer, wherein the side of the hydrophilic layer facing away from the hydrophobic layer is exposed above the dewatering area 235, i.e., facing the dewatering area 235, and the side of the hydrophobic layer facing away from the hydrophilic layer faces away from the dewatering area 235, and the water vapor in the storage container 200 can be discharged to the outside of the storage container 200 through the moisture permeable membrane 500. While the moisture permeable membrane 500 allows water vapor to pass through, it can also block the permeation of other gases, thereby preventing gas exchange inside and outside the storage container 200.

[0069] The moisture permeable membrane 500 is configured to just close the dewatering area 235, and the deoxygenation component 400 is configured to just close the deoxygenation area 231, that is, the deoxygenation component 400 and the moisture permeable membrane 500 are covered side by side above the breathable area 230 to close the breathable area 230, which can prevent gas exchange inside and outside the storage container 200 and can cause the storage container 200 to remain in a relatively closed state, which is conducive to maintaining a good fresh-keeping atmosphere and improving the fresh-keeping effect.

[0070] Fig.11 yes Figure 5 A schematic diagram of a cover plate 600 of a storage device 150 in a refrigerator 10 is shown.

[0071] The cover plate 600 is disposed above the storage container 200 to make the appearance neat. The cover plate 600 includes a first top cover portion 610, a second top cover portion 620 and a connecting portion 630. The first top cover portion 610 has an appearance that matches the appearance of the air permeable area 230 and is configured to allow water vapor above the moisture permeable membrane 500 to pass through while allowing oxygen generated by the oxygen consumption portion 420 of the deoxygenation component 400 to pass through. The second top cover portion 620 has an appearance that matches the appearance of the dewatering cavity 237 and is configured to be attached to the top of the moisture permeable membrane 500 to fix the moisture permeable membrane 500 and prevent the moisture permeable membrane 500 from being displaced.

[0072] If the moisture permeable film 500 is displaced, a gap will appear between the moisture permeable film 500 and the water removal area 235 , so that the storage container 200 cannot form a closed space, which will reduce the preservation effect of the storage container 200 .

[0073] In this embodiment, the first top cover part 610 and the second top cover part 620 are also provided with array-arranged through holes. The position and size of the through holes above the dewatering area 235 are matched with the position and size of the through holes of the dewatering area 235, so as to facilitate the rapid discharge of water vapor above the moisture permeable membrane 500, so as to increase the humidity difference between the two sides of the moisture permeable membrane 500, thereby improving the moisture permeability efficiency of the moisture permeable membrane 500; the position of the through holes above the deoxygenation area 231 is matched with the position of the deoxygenation area 231, so as to facilitate the rapid discharge of oxygen generated by the oxygen consumption part 420.

[0074] The connecting portion 630 is provided with a plurality of slots configured to engage with the buckles on the back wall of the storage container 200 to fix the cover plate 600. The connecting portion 630 is hollowed out above the air induction channel 311, and the shape and position of the hollowed-out portion 631 match the position and shape of the air induction channel 311.

[0075] In this embodiment, when the deoxygenation component 400 and the moisture permeable membrane 500 are applied to the refrigerator 10, the storage container 200, the moisture permeable membrane 500, the deoxygenation component 400, the draft component 300, and the cover plate 600 can be integrated into one to form a storage device 150 having both deoxygenation and moisture permeation functions; the storage device 150 is placed as a whole in the storage compartment 111 of the refrigerator 10, and the electrochemical reaction performed by the deoxygenation component 400 in the energized state can be used to reduce the oxygen content in the storage container 200, so that a low-oxygen fresh-keeping atmosphere is formed in the storage container 200.

[0076] In the process of forming the storage device 150, the deoxygenation component 400 can be first snapped into the deoxygenation chamber 232, the air induced component 300 can be fixed above the air induced area 240, the moisture permeable membrane 500 can be installed in the dewatering chamber 237, and then the cover plate 600 can be fixed above the deoxygenation component 400 and the moisture permeable membrane 500, and the air induced channel 311 can be exposed to the outside of the storage device 150.

[0077] In some optional embodiments, the storage device 150 may further include an electrolysis fan. During the process of forming the storage device 150, the electrolysis fan may first be connected and fixed to the second elastic frame 460 of the deoxygenation component 400, and then the mounting frame 440 of the deoxygenation component 400 may be snapped into the deoxygenation chamber 232.

[0078] In the refrigerator 10 of this embodiment, the deoxygenation component 400 is arranged above the air permeable area 230 on the top surface of the storage container 200, and is configured to electrolyze the water vapor outside the storage container 200 and consume the oxygen inside the storage container 200 through an electrochemical reaction; the air induction area 240 is arranged on one side of the air permeable area 230, and the air induction area 240 is adjacent to the return air port 132, and the air induction component 300 is arranged above the air induction area 240, and is configured to guide the return air flow of the storage compartment 111 at least partially to the deoxygenation component 400, so that the water vapor in the return air flow can be used to provide the deoxygenation component 400 with the reactants required for the electrochemical reaction, and the deoxygenation efficiency of the deoxygenation component 400 can be improved without separately providing a water source or a water delivery device for the deoxygenation component 400, thereby simplifying the structure of the refrigerator 10 equipped with the deoxygenation component 400 and saving the manufacturing cost.
