Description

Technical Field

[0001] The invention relates to a refrigeration and freezing device, in particular to a refrigerator and an electrolytic deoxidation device thereof. Background Art

[0002] In the prior art, there is a refrigerator capable of reducing the oxygen content in the refrigerator storage compartment. The working principle of the refrigerator is to separate and discharge the oxygen in the storage compartment by electrolysis to achieve the purpose of deoxygenation and freshness preservation.

[0003] In order to prevent the electrolyte from flowing out and polluting the environment during transportation and installation, a deoxygenation device with a leak-proof function has appeared in the prior art. Specifically, a surrounding conduit is arranged on the top of the liquid storage tank, and the surrounding conduit has a protruding portion at any periphery of the liquid storage tank to achieve leak-proofing.

[0004] However, the leakage prevention scheme in the prior art also has certain defects. The travel of the surrounding conduit is too long and difficult to disassemble, which is not conducive to the operation of adding electrolyte. Once the deaerator is turned over, some liquid will inevitably remain in the conduit, which is difficult to completely discharge, affecting the air permeability. Even when the exhaust pressure is too high, the liquid will directly spray out from the conduit, causing an accident. Summary of the invention

[0005] An object of the present invention is to overcome at least one defect in the prior art and to provide a refrigerator and an electrolytic deoxidation device thereof.

[0006] A further object of the present invention is to slow down the rate at which electrolyte flows out of the exhaust and liquid injection ports.

[0007] Another further object of the present invention is to avoid liquid accumulation in the exhaust pipe.

[0008] In particular, the present invention provides an electrolytic deoxidation device for separating oxygen in the air of a storage compartment of a refrigerator through an electrochemical reaction, the electrolytic deoxidation device comprising: a shell, an electrolytic chamber for containing an electrolyte is defined within the shell, and an exhaust and liquid injection port is provided on the top of the shell; and an exhaust pipe, one end of which is connected to the exhaust and liquid injection port, and the exhaust pipe is bent multiple times along the shell to slow down the flow rate of the electrolyte being poured out of the electrolytic chamber.

[0009] Optionally, the exhaust pipe includes: a first straight pipe section, a first end of which is connected to the exhaust liquid injection port and extends upward; a first curved pipe section, a first end of which is formed at the second end of the first straight pipe section and bends and extends downward; a second straight pipe section, a first end of which is formed at the second end of the first curved pipe section and extends downward; a second curved pipe section, a first end of which is formed at the second end of the second straight pipe section and bends and extends upward; a third straight pipe section, a first end of which is formed at the second end of the second curved pipe section and extends upward.

[0010] Optionally, the electrolytic deoxidation device also includes: a cap, which includes a cap body and a pipeline bracket formed on one side of the cap body, the cap body is detachably connected to the exhaust and liquid injection port, and an air inlet connected to the exhaust and liquid injection port is formed on the cap body, and the pipeline bracket has a through hole; the first end of the first straight pipe section is connected to the air inlet, and the third straight pipe section is passed through the through hole.

[0011] Optionally, the diameters of the sections of the exhaust pipe are equal and smaller than the diameter of the air inlet.

[0012] Optionally, a partial section of the exhaust pipe protrudes from at least one side peripheral wall of the housing.

[0013] Optionally, the shell has an oxygen inlet open to one side; and the electrolytic deoxidation device also includes: a cathode plate, arranged at the oxygen inlet to define an electrolysis chamber together with the shell, configured to consume oxygen inside the storage compartment through an electrochemical reaction; an anode plate, arranged in the electrolysis chamber, configured to provide reactants to the cathode plate through an electrochemical reaction.

[0014] Optionally, the shell is flat; and the oxygen inlet is opened on a wider side of the shell.

[0015] Optionally, the exhaust and liquid injection port is arranged on a side of the shell close to the anode plate.

[0016] Optionally, the cathode plate includes a catalytic layer, a first waterproof and breathable layer, a conductive layer and a second waterproof and breathable layer which are sequentially arranged along the shell from the inside to the outside.

[0017] In particular, the present invention also provides a refrigerator comprising any one of the above-mentioned electrolytic deoxidation devices.

[0018] In the electrolytic deoxidation device of the present invention, since the exhaust pipe is arranged at the exhaust injection port, and the exhaust pipe is bent many times, when the electrolytic deoxidation device is abnormal (such as tipping over, standing upside down, etc.), the electrolyte in the electrolytic chamber must first pass through the exhaust pipe when flowing out through the exhaust injection port, and the bent exhaust pipe extends and bends the electrolyte outflow path, slowing down the electrolyte outflow rate. In addition, the electrolyte is also subject to the resistance along the way of the inner wall of the exhaust pipe during the outflow process, so that the outflowing electrolyte flow rate is reduced, and it may even be impossible for the electrolyte to be discharged from the exhaust pipe under the action of atmospheric pressure, thereby achieving a leak-proof effect.

[0019] Furthermore, in the electrolytic deoxidation device of the present invention, the exhaust pipe is bent twice by 180 degrees, and the first curved pipe section and the second curved pipe section are respectively connected between the first straight pipe section and the second straight pipe section, and between the second straight pipe section and the third straight pipe section, so as to realize the turning of the exhaust pipe. The exhaust pipe bent twice can prevent leakage and is not easy to store residual electrolyte.

[0032] See also Figures 1 to 3 , Figure 1 is a schematic diagram of a refrigerator 1 according to an embodiment of the present invention, Figure 2 is a partial cross-sectional view of a refrigerator 1 according to an embodiment of the present invention, Figure 3 2 is an exploded view of a refrigerator 1 according to another embodiment of the present invention, wherein the outer shell is hidden. The present invention provides a refrigerator 1, which generally includes a box body 100 and a door body 200.

[0033] The box body 100 may include an outer shell and a storage container, and the outer shell is located at the outermost side of the whole refrigerator 1 to protect the whole refrigerator 1. The number of storage containers can be multiple, and generally include a drawer assembly 400 and multiple inner tanks 300. The storage container is wrapped by the outer shell, and the space between the storage container and the outer shell is filled with a heat-insulating material (forming a foaming layer) to reduce the heat dissipation of the storage container to the outside.

[0034] See also Figure 2 Each inner liner 300 may define a storage compartment 310 that opens forward, and the plurality of storage compartments 310 may be configured as a refrigerator, a freezer, or a temperature-changing chamber, etc. The number and function of the specific storage compartments 310 may be configured according to pre-determined requirements. The door body 200 may be movably disposed in front of the inner liner 300 to open and close the storage compartment 310 of the inner liner 300. For example, the door body 200 may be hingedly disposed on one side of the front of the box body 100 to open and close the storage space by pivoting.

[0035] See also Figure 3 The drawer assembly 400 may include a drawer body 410 and a cylinder body 420. The interior of the drawer body 410 defines a storage compartment 310, and the drawer body 410 is pullably connected to the cylinder body 420 via a slide rail assembly 430. The user can open and close the drawer body 410 by pulling to take out the food therein.

[0036] See also Figure 2 and Figure 3 In some embodiments, the refrigerator 1 may further include an electrolytic deoxidation device 500 , which may be used to reduce the oxygen content in the storage compartment 310 of the inner tank 300 or the drawer body 410 .

[0037] The storage container is provided with an air flow outlet 320 for discharging the air therein. The electrolytic deoxidation device 500 can be arranged outside the storage container and directly or indirectly connected to the air flow outlet 320 of the storage container, so that the air in the storage compartment 310 can reach the electrolytic deoxidation device 500 through the air flow outlet 320, and the electrolytic deoxidation device 500 consumes the oxygen in the air flow discharged from the storage compartment 310 through an electrochemical reaction, so as to achieve the purpose of reducing the oxygen content in the storage compartment 310.

[0038] In some specific embodiments, the electrolytic deoxidation device 500 can be directly installed on the outside of the storage container, and its cathode is close to the air flow port 320. For example, the inner container 300 is provided with the air flow port 320, and the electrolytic deoxidation device 500 is directly installed on the outside of the inner container 300 and is connected with the air flow port 320, so that the air in the storage compartment 310 is introduced into the electrolytic deoxidation device 500 to separate the oxygen in the air.

[0039] For another example, see Figure 3 A plurality of air flow openings 320 may be provided on the rear wall of the cylinder 420 of the drawer assembly 400, and the electrolytic deoxidation device 500 is fixedly connected to the outside of the rear wall of the cylinder 420. Correspondingly, a recessed portion 440 is formed at a position of the rear wall of the drawer body 410 opposite to the air flow opening 320, so that the air of the drawer body 410 can be guided out from the ventilation hole, and the oxygen in the air in the storage compartment 310 can also be separated.

[0040] See also Figure 2 In some other specific embodiments, the electrolytic deoxidizer 500 can also be indirectly connected to the air flow outlet 320 of the storage container. For example, the electrolytic deoxidizer 500 can be connected to the air flow outlet 320 of the storage container through a connecting component 600. The connecting component 600 is arranged in the box 100 and is formed with a connecting channel 601 for connecting the storage compartment 310 with the external environment of the box 100. The first end K1 of the connecting channel 601 is formed with a mounting frame (not shown in the figure) for mounting the electrolytic deoxidizer 500, and the second end K2 is connected to the air flow outlet 320 of the storage container, so that the air in the storage container can be guided to the electrolytic deoxidizer 500 through the connecting component 600. In addition, the connecting component 600 can also extend its first end K1 to the outside of the box 100, so that when the electrolytic deoxidizer 500 is installed in the mounting frame, it is at least partially exposed to the outside of the refrigerator 1, so that oxygen can be discharged smoothly to the external environment.

[0041] See also Figure 4 and Figure 5 , Figure 4 is a schematic diagram of an electrolytic deoxidation device 500 in a refrigerator 1 according to an embodiment of the present invention, Figure 5 1 is an exploded view of an electrolytic deoxidation device 500 in a refrigerator 1 according to an embodiment of the present invention. In some embodiments, the electrolytic deoxidation device 500 may further include a housing 501 , a cathode plate 510 , and an anode plate 520 .

[0042] The shell 501 defines an electrolyte chamber for containing an electrolyte. The electrolyte may be an alkaline electrolyte, such as 1 mol / L NaOH, and its concentration may be adjusted according to actual needs. One wall of the shell 501 is open to one side to form an oxygen inlet 512.

[0043] The cathode plate 510 can be disposed at the oxygen inlet 512 to define a liquid storage cavity together with the housing 501, and the cathode plate 510 faces the air flow outlet 320, and is used to consume oxygen inside the storage compartment 310 through an electrochemical reaction under the action of the electrolysis voltage and generate negative ions. For example, oxygen in the air can undergo a reduction reaction at the cathode plate 510, that is, O2+2H2O+4e-→4OH-.

[0044] The anode plate 520 is disposed in the electrolysis chamber and is located on the side of the cathode plate 510 facing away from the airflow port 320, and is used to provide reactants (such as electrons) to the cathode plate 510 through an electrochemical reaction to separate oxygen from the air. For example, OH- generated by the cathode plate 510 can undergo an oxidation reaction at the anode plate 520 to generate oxygen to separate oxygen from the air, that is: 4OH-→O2+2H2O+4e-.

[0045] In some embodiments, the anode plate 520 may be made of nickel. The cathode plate 510 is sequentially provided with a catalytic layer, a first waterproof and breathable layer, a conductive layer, and a second waterproof and breathable layer from the inside to the outside. The "inside" refers to the inside of the housing 501, that is, the electrolysis chamber, and the "outside" refers to the outside of the housing 501, that is, the side of the cathode plate 510 away from the electrolysis chamber.

[0046] The catalytic layer can use a metal / carbon catalyst, and the metal can be a precious metal or a rare metal, for example, selected from the group consisting of metal platinum, metal gold, metal silver, metal manganese and metal rubidium. The carbon can be carbon black. The first waterproof and breathable layer and the second waterproof and breathable layer can be waterproof and breathable membranes, so that the electrolyte cannot seep out of the liquid storage cavity, and the air can enter the liquid storage cavity through the first waterproof and breathable layer and the second waterproof and breathable layer. The conductive layer is made into a corrosion-resistant metal current collecting net, such as metal nickel, metal titanium, etc., so that it not only has better conductivity, corrosion resistance and supporting strength, but also because the cathode plate 510 itself has a certain strength, it can fully meet the sealing strength requirements of the liquid storage cavity. In addition, the cathode plate 510 uses two layers of waterproof and breathable layers to effectively prevent leakage caused by electrolyte corrosion.

[0047] See also Figures 5 to 8 , Figure 6 yes Figure 5 A in the enlarged view, Figure 7 is a schematic diagram of a support member 544 in an electrolytic deoxidation device 500 according to an embodiment of the present invention, Figure 8 yes Figure 7 In some embodiments, the electrolytic deoxidation device 500 may further include a separator 530 and a fixing assembly 540 .

[0048] The separator 530 can be arranged between the cathode plate 510 and the anode plate 520, and a plurality of protrusions 532 facing the anode plate 520 are formed thereon. After assembly, the protrusions 532 abut against the anode plate 520, and the cathode plate 510 abuts against the side of the separator 530 away from the protrusions 532 to prevent the cathode plate 510 from contacting the anode plate 520, thereby avoiding a short circuit of the electrolytic deoxidation device 500.

[0049] The fixing assembly 540 may include a metal frame 542 and a support member 544. The metal frame 542 is attached to the outer side of the cathode plate 510, and the metal frame 542 protrudes outward to form a surrounding portion 5422; the support member 544 is arranged on the outer side of the metal frame 542, and has an inner ring 5442 and an outer ring 5444, and a plug-in groove 5442a is formed on the inner ring 5442, and the outer ring 5444 is fixedly connected to the shell 501. After assembly, the metal frame 542 is pressed against the cathode plate 510, and the surrounding portion 5422 extends into the plug-in groove 5442a to position the metal frame 542 and the support member 544, and the outer ring 5444 is fixedly connected to the shell 501, and the metal frame 542 and the cathode plate 510 are directly fixed to the shell 501.

[0050] In some embodiments, reinforcing ribs 5446 are formed between the outer ring 5444 and the inner ring 5442 of the support member 544 and inside the inner ring 5442 for fixing the outer ring 5444 and the inner ring 5442 of the support member 544 and shaping the outer ring 5444 and the inner ring 5442 of the support member 544 to prevent them from being deformed by external forces.

[0051] See also Fig. 9 and Fig.10 , Fig. 9 is an exploded view of an electrolytic deoxidation device 500 in a refrigerator 1 according to a further embodiment of the present invention, which shows the positional relationship between a housing 501, a cap 560 and an exhaust pipe 550. Fig.10 yes Fig. 9 Enlarged view of point C in the middle. In some embodiments, the electrolytic deoxidation device 500 may further include an exhaust pipe 550 .

[0052] An exhaust and liquid injection port 502 is provided on the top of the shell 501. The exhaust and liquid injection port 502 can not only be used to discharge the oxygen generated on the anode plate 520, but also be used by users or maintenance personnel to add electrolyte into the electrolytic chamber without disassembling the electrolytic deoxidation device 500 as a whole, which is safe and convenient.

[0053] One end of the exhaust pipe 550 is connected to the exhaust liquid injection port 502, and the exhaust pipe 550 is bent multiple times to slow down the flow rate of the electrolyte pouring out of the electrolytic chamber. The exhaust pipe 550 can be bent twice, three times or more, and the embodiment does not specifically limit the number of bends of the exhaust pipe 550.

[0054] Since the exhaust pipe 550 is arranged at the exhaust injection port 502, and the exhaust pipe 550 turns and bends many times to be in a bent shape, when the electrolytic deoxidation device 500 has an abnormal situation (such as tipping over, standing upside down, etc.), the electrolyte in the electrolytic chamber must first pass through the exhaust pipe 550 when flowing out through the exhaust injection port 502, and the bent exhaust pipe 550 extends and bends the outflow path of the electrolyte, delaying the outflow time of the electrolyte. In addition, the electrolyte is also subject to the resistance along the way of the inner wall of the exhaust pipe 550 during the outflow process, so that the flow rate of the electrolyte flowing out is reduced, and it may even be impossible for the electrolyte to be discharged from the exhaust pipe 550 under the action of atmospheric pressure, thereby achieving a leak-proof effect.

[0055] As described in the background technology section, the leakage prevention scheme of the prior art is not only difficult to disassemble for fluid replenishment due to the long travel of the catheter, but also easily stores residual electrolyte, affecting air permeability. In order to overcome the above-mentioned defects of the prior art, in the electrolytic deoxygenation device 500 of this embodiment, the exhaust pipe 550 uses a turning method to extend and bend the outflow path of the electrolyte, which effectively solves the leakage prevention problem, and the exhaust adopts a turning method so that it will not protrude on any peripheral wall of the shell 501, so that the exhaust pipe 550 occupies less space and is easy to disassemble, which is convenient for maintenance personnel to add electrolyte.

[0056] See also Fig.10 In some further embodiments, the exhaust pipe 550 may include a first straight pipe section 551, a first curved pipe section 552, a second straight pipe section 553, a second curved pipe section 554, and a third straight pipe section 555. The first end of the first straight pipe section 551 is connected to the exhaust liquid injection port 502 and extends upward, the first end of the first curved pipe section 552 is formed at the second end of the first straight pipe section 551, and bends and extends downward, the first end of the second straight pipe section 553 is formed at the second end of the first curved pipe section 552, and extends downward, the first end of the second curved pipe section 554 is formed at the second end of the second straight pipe section 553, and bends and extends upward, and the first end of the third straight pipe section 555 is formed at the second end of the second curved pipe section 554, and extends upward.

[0057] That is, the exhaust pipe 550 of this embodiment is bent 180° twice, and the first curved pipe section 552 and the second curved pipe section 554 are used to connect the first straight pipe section 551 and the second straight pipe section 553, and the second straight pipe section 553 and the third straight pipe section 555, respectively, to realize the turning of the exhaust pipe 550.

[0058] The inventors have found through a large number of experiments that the exhaust pipe 550 that has been bent once may still leak, and the exhaust pipe 550 that has been bent more than three times may still have accumulated liquid in the pipe after the electrolytic deoxidation device 500 is tilted and straightened, while the exhaust pipe 550 that has been bent twice is leak-proof and not easy to store residual electrolyte.

[0059] In this embodiment, one end of the exhaust pipe 550 can be directly connected to the exhaust liquid injection port 502, or can be indirectly connected to the exhaust liquid injection port 502. Specifically, when the exhaust pipe 550 is indirectly connected to the exhaust liquid injection port 502, the electrolytic deoxidation device 500 can also include a cap 560, the cap 560 includes a cap body 561 and a pipeline support 562 formed on one side of the cap body 561, the cap body 561 is detachably connected to the exhaust liquid injection port 502, and the cap body 561 is formed with an air inlet 563 connected to the exhaust liquid injection port 502, and the pipeline support 562 has a through hole 564. The first end of the first straight pipe section 551 is connected to the air inlet 563, and the third straight pipe section 555 is penetrated through the through hole 564.

[0060] The cap body 561 can be installed on the exhaust and liquid filling port 502 in a detachable manner by means of snap-fit, threaded connection, etc., and the air inlet 563 on the cap body 561 can also be tightly connected to one end of the exhaust pipe 550 by means of snap-fit, interference fit or air circuit quick connector.

[0061] The pipe support 562 is disposed on one side of the cap body 561. When one end of the exhaust pipe 550 is connected to the air inlet 563, the second straight pipe section 553 of the exhaust pipe 550 first extends downward, and then the third straight pipe section 555 extends upward, and passes through the through hole 564 for limiting and fixing. That is, the cap 560 can fix the exhaust pipe 550 at both ends and keep it in a double-bent state.

[0062] After the electrolytic deoxidation device 500 has been used for a period of time, the user or maintenance personnel can directly remove the cap 560 to remove the exhaust pipe 550 and expose the exhaust liquid injection port 502 for easy filling of electrolyte. After the filling is completed, the cap 560 can be directly restored to its original position, which is simple to operate.

[0063] In some embodiments, the diameters of the various sections of the exhaust pipe 550 are equal and smaller than the diameter of the air inlet 563, so that the exhaust pipe 550 can be sleeved on the air inlet 563. In addition, since the diameter of the exhaust pipe 550 is smaller than the diameter of the air inlet 563, and since the viscosity of liquid is generally greater than that of gas under the same external conditions, the resistance of the liquid to the exhaust pipe 550 with a smaller diameter is greater, while the resistance of the gas to the exhaust pipe 550 is smaller, which can not only effectively slow down the flow rate of the electrolyte in the exhaust pipe 550 when pouring, but also has less impact on the emission of oxygen under normal use.

[0064] In some embodiments, a partial section of the exhaust pipe 550 protrudes from at least one side peripheral wall of the housing 501. For example, a partial section of the exhaust pipe 550 may protrude from at least one of the side of the housing 501 where the cathode plate 510 is disposed, the side of the housing 501 away from the cathode plate 510, or other side surfaces. In this way, when the electrolytic deoxidation device 500 is tilted and the section of the exhaust pipe 550 protruding from the housing 501 is located at the top, it is ensured that the exhaust pipe 550 has a section higher than the housing 501, thereby preventing the electrolyte from being discharged from the exhaust pipe 550.

[0065] In some embodiments, the housing 501 is flat, and the oxygen inlet 512 is opened on the wider side of the housing 501. Since the cathode plate 510 covers the oxygen inlet 512, the larger the oxygen inlet 512, the larger the area of ​​the cathode plate 510, so that the contact area between the cathode plate 510 and the air is larger, thereby improving the electrolysis efficiency of the electrolytic deoxidation device 500. In addition, the housing 501 is set to be flat, which can also shorten the width of the electrolytic deoxidation device 500, reduce its occupied thickness, and save space.

[0066] In some embodiments, the exhaust and liquid injection port 502 can be disposed on a side of the housing 501 close to the anode plate 520. That is, relative to the cathode plate 510, the exhaust and liquid injection port 502 is closer to the anode plate 520, and the exhaust and liquid injection port 502 can be disposed on the top rear side of the housing 501, which can shorten the exhaust path of oxygen and facilitate the rapid exhaust of oxygen generated by the anode plate 520.

[0067] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
