Detailed Description
Fig. 1 is a schematic view of an internal structure of a refrigerator 10 according to one embodiment of the present invention. The refrigerator 10 may generally include a cabinet 200, a storage container 300, and a cold guide 400.
The cabinet 200 has a storage compartment 210 and a cooling chamber 220 formed therein at one side of the storage compartment 210 for cooling the storage compartment 210. The cooling method of the storage compartment 210 of the refrigerator 10 may be an air-cooling type, a direct cooling type or a mixed cooling type, and the present embodiment will be described in detail with respect to the structure of the refrigerator 10 by taking the air-cooling type as an example. Those skilled in the art should appreciate that the present embodiment is fully capable of expanding the structure of the refrigerator 10 to accommodate other cooling modes, and the structure is not illustrated here.
In this embodiment, an evaporator may be disposed in the cooling cavity 220 for exchanging heat with the airflow flowing through the cooling cavity, so that a low-temperature heat exchange airflow is generated in the cooling cavity 220. The cooling chamber 220 may supply cooling to the storage compartment 210 by delivering a heat exchange air flow to the storage compartment 210.
The storage container 300 is disposed in the storage compartment 210, and has an air inlet 310. The storage container 300 may be a drawer, and includes a cylinder 330 and a drawer body 340 drawably disposed on the cylinder 330. The air inlet 310 may be provided on the cylinder 330. When the drawer body 340 is positioned in the cylinder 330, the inner space of the storage container 300 can input only a heat exchange air flow through the air inlet 310.
The cold guide device 400 is disposed in the storage compartment 210, and an airflow channel 450 is formed therein to communicate the cold supply cavity 220 with the air inlet 310. That is, the heat exchange air flow in the cooling chamber 220 may flow through the air flow passage 450 of the cold guide device 400 and then flow into the inner space of the storage container 300 through the air inlet 310.
Because the air inlet 310 is formed in the storage container 300, the cold guide device 400 is provided with the airflow channel 450 for communicating the cold supply cavity 220 with the air inlet 310, so that the cold guide device 400 can directly convey cold in the cold supply cavity 220 into the storage container 300, the refrigerator 10 can adjust the temperature of a part of space in the storage chamber 210, and the diversified temperature adjustment requirements of users are met.

In some alternative embodiments, the refrigerator 10 may further include an electrolytic oxygen removal device 100. A portion of the electrolytic oxygen removal device 100 is in communication with the gas flow channel 450 for consuming oxygen from the gas flow through the gas flow channel 450 by an electrochemical reaction.
Fig. 4 is another schematic view of a portion of the refrigerator 10 shown in fig. 3, and the cold guide device 400 in fig. 4 is a perspective view, illustrating the position of the electrolytic oxygen removal device 100 relative to the airflow channel 450. A portion of the electrolytic oxygen removal device 100 described above may be referred to as the cathode plate 120 of the electrolytic oxygen removal device 100. A part of the electrolytic oxygen removing device 100 is in communication with the gas flow passage 450, and may mean that the cathode plate 120 is directly disposed in the gas flow passage 450, or may mean that the cathode plate 120 is in gas flow communication with the gas flow passage 450, or may mean that the cathode plate 120 is disposed on the wall surface of the gas flow passage 450, as long as the gas flowing through the gas flow passage 450 can flow through the cathode plate 120.
Since a portion of the electrolytic deoxygenator device 100 is in communication with the airflow channel 450, oxygen in the airflow flowing through the airflow channel 450 can be consumed, which enables the refrigerator 10 to deliver a low oxygen flow to a portion of the space within the storage compartment 210.
By combining the electrolytic oxygen removal device 100 and the cold guide device 400, the low-oxygen airflow can be provided for the storage container 300, and the low-temperature airflow can be provided for the storage container 300, so that the refrigerator 10 can create a low-oxygen fresh-keeping atmosphere for a part of space in the storage compartment 210, and the fresh-keeping capacity of the refrigerator 10 can be improved.
Fig. 5 is a schematic view of a cold guide 400 of the refrigerator 10 shown in fig. 4. The cold guiding device 400 is provided with a first opening 421 for communicating the airflow channel 450 with the storage compartment 210. And the electrolytic oxygen removal device 100 is disposed in the first opening 421 to close the airflow channel 450, so as to ensure the air tightness of the airflow channel 450 and improve the cold energy transmission efficiency. In this embodiment, the cold guide device 400 may be located above the storage container 300, and the first opening 421 may be located at the top of the cold guide device 400.
By disposing the electrolytic oxygen removal device 100 in the first opening 421, one part of the electrolytic oxygen removal device 100 can be communicated with the gas flow channel 450, and the other part of the electrolytic oxygen removal device 100 can be communicated with the storage chamber 210, so that the electrolytic oxygen removal device 100 can be contacted with oxygen in the gas flow channel 450, and the electrolytic oxygen removal device 100 can discharge gas generated in the electrochemical reaction process to the outside of the storage container 300.
Electrolytic oxygen removal device 100 includes a cathode plate 120 and an anode plate 140. Cathode plate 120 faces gas flow channel 450, i.e., cathode plate 120 is in gas flow communication with gas flow channel 450. The cathode plate 120 serves to consume oxygen in the gas flow passing through the gas flow channel 450 through an electrochemical reaction under the action of an electrolysis voltage. For example, oxygen in the air may undergo a reduction reaction at cathode plate 120, i.e.: o is2+2H2O +4e- → 4 OH-. The anode plate 140 faces away from the gas flow channel 450, i.e., the anode plate 140 is not in gas flow communication with the gas flow channel 450, in this embodiment, the anode plate 140 may be disposed on the side of the cathode plate 120 facing away from the gas flow channel 450, i.e., the anode plate 140 is disposed facing away from the gas flow channel 450. For example, for electrolytic deoxygenation device 100 in an operating state, anode plate 140 is positioned above cathode plate 120. The anode plate 140 serves to provide reactants, such as electrons, to the cathode plate 120 through an electrochemical reaction under the action of an electrolysis voltage. OH "produced by cathode plate 120 may undergo an oxidation reaction at anode plate 140 and produce oxygen, i.e.: 4OH- → O2+2H2O+4e-。
The disposition of the anode plate 140 facing away from the air flow channel 450 can reduce or prevent oxygen generated by the anode plate 140 from entering the air flow channel 450, so as to prevent the oxygen generated by the anode plate 140 from damaging the low-oxygen fresh-keeping atmosphere in the storage container 300.
The anode plate 140 of the present embodiment may be made of nickel. The cathode plate 120 may be sequentially provided with a catalyst layer, a first waterproof breathable layer, a current collecting layer, and a second waterproof breathable layer from the inside to the outside. Where "outer" means close to gas flow channel 450 and "inner" means away from gas flow channel 450, the catalytic layer is located at the innermost side of cathode plate 120 relative to the other structure of cathode plate 120, so as to be in contact with the electrolyte.
The catalytic layer may be a metal/carbon catalyst, wherein the metal may be a noble metal or a rare metal, and may be selected from the group consisting of platinum, gold, silver, manganese, and rubidium, for example. The carbon may be carbon black. First waterproof ventilative layer and the waterproof ventilative layer of second can be waterproof ventilated membrane to make electrolyte can't ooze from the stock solution chamber, and the air can see through first waterproof ventilative layer and the waterproof ventilative layer of second and reach the catalysis layer. The current collecting layer can be made into a corrosion-resistant metal current collecting net, such as metal nickel, metal titanium and the like, so that the current collecting layer not only has better conductivity, corrosion resistance and supporting strength. And because cathode plate 120 itself has certain intensity, can satisfy the sealing strength demand of stock solution chamber completely, cathode plate 120 adopts two-layer waterproof ventilative layer also can prevent effectively because the leakage that electrolyte corrosion arouses in addition.
In some embodiments, the refrigerator may further include a power supply module, such as a battery. The power module is disposed proximate to the electrolytic oxygen removal device 100 and provides power to the electrolytic oxygen removal device 100. The anode plate 140 may be disposed in the reservoir chamber spaced apart from the cathode plate 120. The anode plate 140 has an anode power supply terminal 142 that extends out of the case 110 and is connected to the positive electrode of an external power source.
Fig. 6 is another schematic view of the cold guiding device 400 of the refrigerator 10 shown in fig. 5. The cold guide device 400 further defines a second opening 422 and a third opening 431, wherein the second opening 422 is communicated with the cold supply chamber 220, the third opening 431 is communicated with the air inlet 310, and an air flow channel 450 penetrating through the cold guide device 400 is formed between the second opening 422 and the third opening 431.
In this embodiment, an air supply outlet 211 is communicated between the storage compartment 210 and the cooling cavity 220, and the cooling cavity 220 supplies heat exchange air flow to the storage compartment 210 through the air supply outlet 211. As for the communication manner of the second opening 422 with the cooling chamber 220 and the communication manner of the third opening 431 with the air inlet 310, for example, the second opening 422 may be opposite to the air blowing port 211 so that the second opening 422 communicates with the cooling chamber 220. The third opening 431 may be embedded in an inner circumference of the air inlet 310 such that the third opening 431 communicates with the air inlet 310. In some embodiments, the second opening 422 may be provided with an air inducing piece 460, an air inducing channel for the heat exchange air flow to pass through is formed inside the air inducing piece, and the air inducing channel is arranged in a tapered manner along the extending direction of the air flow channel 450; the air inducing member 460 is inserted into the air flow passage 450 along the inner circumference of the second opening 422 for promoting convergence of the heat exchange air flow entering the second opening 422.
Regarding the relative positions of the cooling chamber 220, the storage compartment 210 and the cold guide device 400, for example, the cooling chamber 220 may be located at the rear side of the storage compartment 210, the air inlet 310 may be located at the top of the storage container 300, and the cold guide device 400 may be located above the storage container 300 and in front of the air blowing port 211, such that the second opening 422 is opposite to the air blowing port 211 to communicate with the cooling chamber 220. With such an arrangement, the storage container 300 can support the cold guide device 400, which can improve the structural stability of the refrigerator 10 as a whole and prevent the cold guide device 400 from being blocked by the airflow channel 450 due to shaking. Those skilled in the art should understand that the relative positions of the cooling chamber 220, the storage compartment 210 and the cooling device 400 can be easily adjusted based on the embodiment, and the description is not exhaustive.
The cold guiding device 400 may include a base plate portion 420 and an extension portion 430.

The extension 430 extends downward from the second end of the base plate portion 420 to a third opening 431, and forms the third opening 431 communicating with the air inlet 310. The extension portion 430 forms a second section 452 of the gas flow channel 450 between the second end of the base plate portion 420 and the third opening 431. The heat-exchange air flow in the cooling chamber 220 may sequentially pass through the air supply outlet 211, the second opening 422, the first section 451 of the air flow passage 450, the second section 452 of the air flow passage 450, and the air inlet 310, thereby flowing into the inner space of the storage container 300.
The airflow channel 450 formed by connecting the first section 451 extending horizontally and the second section 452 extending vertically in series is constructed by the base plate portion 420 and the extending portion 430, so that the resistance of the heat exchange airflow flowing along the airflow channel 450 can be reduced, and the cold guiding efficiency of the cold guiding device 400 can be improved.
In this embodiment, the base plate portion 420 may be substantially flat and rectangular, and may be laid flat above the container 300. And the width direction of the base plate portion 420 may be parallel to the lateral extension direction of the refrigerator 10, and the length direction thereof may be parallel to the front-rear extension direction of the refrigerator 10. The first end surface of the substrate portion 420 faces the air blowing port 211. The second end of the base plate portion 420 faces away from the air blowing port 211. The extension portion 430 may extend substantially vertically downward from the second end of the base plate portion 420 to the third opening 431. In some embodiments, the extension 430 and the third opening 431 may be sealed with a sealing ring or a sealing rubber strip to prevent air leakage.
A rib 423 is formed by extending a part of the lower surface of the base plate portion 420 downward, so that a space is formed between the lower surface of the base plate portion 420 and the upper surface of the storage container 300, which facilitates the transfer of the cooling energy of the storage compartment 210 to the storage container 300, and the storage container 300 can simultaneously receive the cooling energy directly from the storage compartment 210 and the cooling energy directly from the cooling cavity 220, thereby enabling the refrigerator 10 to perform dual temperature adjustment for a part of the space in the storage compartment 210.
In some further embodiments, the refrigerator 10 may further include a temperature sensor (not shown) and a cool-conducting fan 500.
Wherein, the temperature sensor is disposed in the storage container 300 for detecting the temperature in the storage container 300. The cool-guiding fan 500 is disposed in the airflow channel 450 and is used for promoting the air in the cool supplying cavity 220 to flow into the storage container 300 through the airflow channel 450 and then through the air inlet 310. In this embodiment, the temperature sensor may start to detect the temperature in the storage container 300 after the door 600 of the refrigerator 10 is closed.
The induced cooling fan 500 may be an axial flow fan 500, an air suction port thereof may be directed toward the first end of the substrate portion 420 and directed toward the second opening 422, and an air discharge port thereof may be directed toward the second end of the substrate portion 420. In this embodiment, the cool air guiding fan 500 may be configured to be turned on when the temperature in the storage container 300 is higher than a preset temperature threshold value, so as to promote the formation of a heat exchange airflow directly flowing from the cool supply cavity 220 to the storage container 300, thereby rapidly cooling the storage container 300. The electrolytic deoxygenator device 100 may be turned on in synchronization with the induced draft fan 500 to provide a low temperature, low oxygen heat exchange gas flow to the storage container 300. Before the electrolytic oxygen removal device 100 and the induced-cooling fan 500 are turned on, the refrigerator 10 may also turn on the refrigeration system to generate a heat exchange air flow in the cooling chamber 220.
In still further embodiments, the refrigerator 10 may further include a controllable damper (not shown) disposed at the second opening 422 for opening the second opening 422 when the temperature in the storage container 300 is above a preset temperature threshold, the controllable damper being further configured to close the second opening 422 when the temperature in the storage container 300 is not above the preset temperature threshold. That is, the controllable damper facilitates the air flow passage 450 to communicate with the cooling chamber 220 only when the temperature inside the storage container 300 is higher than a desired value, which can improve the airtightness of the storage container 300 and improve the fresh-keeping effect.
Fig. 7 is a schematic view of the storage container 300 of the refrigerator 10 shown in fig. 3. In still further embodiments, an air return opening (not shown) is communicated between the storage compartment 210 and the cooling cavity 220. The storage container 300 is further opened with an air outlet 320 in air flow communication with the air return opening. That is, the air in the storage container 300 can flow out of the storage container 300 through the air outlet 320 and flow back to the air return opening along with the air of the air return in the storage compartment 210, which can increase the flow rate of the air in the storage container 300, thereby rapidly refreshing the air in the storage container 300.

The housing 110 may have a substantially rectangular parallelepiped shape. One of the walls of the housing 110 (e.g., the bottom wall of the housing 110) may be open to form the oxygen inlet 114 opposite the first opening 421. Cathode plate 120 may be disposed at oxygen inlet 114 and may define, with housing 110, a reservoir chamber for holding an electrolyte. That is, the cathode plate 120 of the present embodiment can be directly used as one of the wall surfaces of the housing 110 for sealing the liquid storage chamber. The opening size of oxygen inlet 114 may be larger than the opening size of first opening 421 so that cathode plate 120 seals first opening 421 as well as oxygen inlet 114. The liquid storage cavity of the electrolytic oxygen removal device 100 can be filled with alkaline electrolyte, such as 0.1-8 mol/L NaOH, and the concentration of the alkaline electrolyte can be adjusted according to actual needs.
A vent (not shown) may be provided near the top of the housing 110, which may reduce or avoid electrolyte leakage. In some further embodiments, the vent may also serve as a fluid infusion port for the electrolyte, and when the electrolyte is insufficient, the electrolyte may be injected into the fluid storage cavity at the vent, which may realize the function reuse of the vent, and is beneficial to simplifying the structure of the electrolytic oxygen removal device 100. In some embodiments, electrolytic oxygen removal device 100 may further include an exhaust tube 160 connected to the exhaust port for directing the gas flowing through the exhaust port to the external environment.

Specifically, the separator 130 has a plurality of protrusions 132 formed on a side thereof facing the anode plate 140, the protrusions 132 abut against the anode plate 140, and the cathode plate 120 abuts against a side of the separator 130 facing away from the protrusions 132 to form a predetermined gap between the cathode plate 120 and the anode plate 140, thereby separating the cathode plate 120 from the anode plate 140.
A fixing assembly 150 may be provided at the outer side of the cathode plate 120, configured to fix the cathode plate 120 at the opening. Specifically, the fixing assembly 150 may further include a metal bezel 152 and a support 154.

The metal frame 152 abuts against the outside of the cathode plate 120, and the metal frame 152 is formed with a surrounding portion 152a protruding outward. The supporting member 154 is disposed at the outer side of the metal frame 152, and has an outer ring 1542 and an inner ring 1544 located inside the outer ring 1542, the outer ring 1542 is fixedly connected to the housing 110, an insertion groove 1544a is formed at the inner side of the inner ring 1544, and the surrounding portion 152a extends into the insertion groove 1544a to fix the metal frame 152 and the cathode plate 120 at the opening. In this embodiment, the metal frame 152 is in direct contact with the cathode plate 120, the metal frame 152 may play a role of pressing the cathode plate 120, and a cathode power supply terminal 152b of the cathode plate 120 may be further disposed on the metal frame 152 to be connected to an external power supply.
The surrounding portion 152a is formed on the metal frame 152 and extends outward to be inserted into the inner ring 1544 insertion groove 1544a of the supporting member 154, so as to position the metal frame 152. Since outer ring 1542 of support member 154 is fixedly connected to housing 110, when standing portion 152a of metal frame 152 is inserted into insertion groove 1544a of support member 154, metal frame 152 can be fixed and positioned by support member 154, so that metal frame 152 presses cathode plate 120.
In some embodiments, a rib 1546 is further formed between the outer ring 1542 and the inner ring 1544 of the supporting member 154 and inside the inner ring 1544, for fixedly connecting the outer ring 1542 and the inner ring 1544 of the supporting member 154, and shaping the outer ring 1542 and the inner ring 1544 of the supporting member 154 to prevent them from being deformed by an external force.
