[0028] Exemplary embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings; however, they are not limited thereto and can be implemented in various forms. It is to be understood that the embodiments described herein are merely exemplary and that the present disclosure is not limited thereto. Rather, the present disclosure is intended to cover all alternatives, modifications and equivalents of the embodiments described herein, including such variations as would be readily apparent to one of ordinary skill in the art having the benefit of this disclosure.

[0029] Referring to Figure 1 , Figure 1 is a schematic diagram of a refrigerator 1 according to an embodiment of the present application. The present application provides a refrigerator 1, which can generally include a cabinet 10 and a door body 20.

[0030] 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. The plurality of inner tanks are wrapped by the outer shell, and the space between the outer shell and the inner tanks is filled with a thermal insulation material (forming a foaming layer) to reduce heat dissipation of the inner tanks to the outside. Each of the inner tanks can define a storage compartment open to the front, and the storage compartment can be configured as a refrigerating compartment, a freezing compartment, a variable temperature compartment, etc., and the number and functions of the specific storage compartments can be configured according to the pre-requisite requirements.

[0031] The door body 20 is movably provided in front of the inner tanks to open and close the storage compartments of the inner tanks, for example, the door body 20 can be provided on one side of the front portion of the cabinet 10 by a hinged manner, and open and close the storage compartments by a pivoting manner.

[0032] The refrigerator 1 can further comprise a drawer assembly 30, which can further comprise a drawer body that is pullably arranged in the storage compartment for a user to take out articles.

[0033] In some embodiments, the refrigerator 1 can further comprise an electrolytic oxygen-removing device 40 that can be arranged on the inner container or the drawer assembly 30, separates oxygen in air flowing therethrough through an electrolytic reaction, and leaves nitrogen in the storage compartment of the inner container or the drawer body, so as to achieve fresh-keeping storage of food.

[0034] Referring to Figure 2 , Figure 2 is a schematic view of the mounting relationship between the cabinet 10 and the electrolytic oxygen-removing device 40 in the refrigerator 1 according to an embodiment of the present application, in which the outer shell and the foaming layer of the cabinet 10 are hidden, Figure 2 It is shown that the electrolytic oxygen-removing device 40 is arranged on the rear wall of the storage compartment, but the electrolytic oxygen-removing device 40 can not be limited thereto, and can also be arranged on the side wall, the top wall, the bottom wall, etc. of the storage compartment, or on the rear wall, the side wall, the bottom wall, etc. of the drawer body. In general, those skilled in the art can arrange the electrolytic oxygen-removing device 40 according to actual conditions after knowing the technical solution of the present embodiment, which is not listed one by one here.

[0035] Referring to Figures 3 to 5 , Figure 3 is a schematic view of the connection relationship among the electrolytic oxygen-removing device 40, the liquid supplementing tank 50, and the waste liquid tank 60 in the refrigerator 1 according to an embodiment of the present application, Figure 4 is an exploded view of the electrolytic oxygen-removing device 40, the liquid supplementing tank 50, and the waste liquid tank 60 in the refrigerator 1 according to an embodiment of the present application, Figure 5 is a sectional view of the electrolytic oxygen-removing device 40 according to an embodiment of the present application.

[0036] In some embodiments, the electrolytic oxygen-removing device 40 can further comprise a cover shell 100 and an electrolytic bin 300, the cover shell 100 has a receiving cavity 102 therein, the electrolytic bin 300 has an electrolytic cavity therein for containing electrolyte, and the electrolytic bin 300 is arranged in the receiving cavity 102, so as to collect electrolyte leaked from the electrolytic cavity by the receiving cavity 102.

[0037] In particular, one side of the electrolytic bin 300 can be opened to form an oxygen inlet (not shown in the figure), and the oxygen inlet can be provided with a cathode plate (not shown in the figure) having a waterproof and air-permeable function, so that air can enter the inside of the electrolytic bin 300 through the cathode plate, and the electrolyte in the electrolytic bin 300 is prevented from flowing out, that is, in the present embodiment, the cathode plate can serve as at least a part of one wall surface of the electrolytic bin 300, and in order to improve the air inlet efficiency, the cathode plate can be arranged to face the storage compartment.

[0038] The cathode plate (not shown in the figure) can be loaded with a negative pole of an external power supply. Air in the storage space undergoes a reduction reaction after entering the electrolysis bin 300, generating negative ions, i.e. O2+2H2O+4e - →4OH - .

[0039] Since the electrolysis bin 300 can contain electrolyte, the anode plate can be arranged in the electrolyte in the electrolysis bin 300 and loaded with a positive pole of an external power supply. The electrolyte can serve as an electrical connection between the cathode plate and the anode plate. The negative ions generated at the cathode plate flow to the anode plate under the action of an electric field and undergo an oxidation reaction at the anode plate to generate oxygen, i.e. 4OH - →O2+2H2O+4e - In this way, oxygen in the air can be separated and discharged, thereby reducing the oxygen content of the air in the storage chamber. Specifically, the electrolysis bin 300 is also provided with an oxygen discharge port 310 (as shown in Figure 4 ), so as to discharge the separated oxygen out of the electrolysis bin 300.

[0040] Referring to Figure 3 and Figure 4 , in some specific embodiments, the electrolysis bin 300 also has a liquid supplement port 320, which can also be connected in communication with an external liquid supplement tank 50 through a liquid supplement pipe 52. The liquid supplement tank 50 contains electrolyte to supplement electrolyte into the electrolysis cavity.

[0041] Since the electrolysis bin 300 contains electrolyte, if improper protection, internal component damage, etc. occur, the electrolyte may leak. Since the electrolyte usually has a certain acidity or alkalinity, the leaked electrolyte can not only cause corrosion of the equipment, but also cause environmental pollution, and even serious accidents.

[0042] In the present embodiment, since the electrolysis bin 300 is arranged in the accommodating cavity 102 of the cover shell 100, if an electrolyte leakage accident occurs, the cover shell 100 can serve as a protective cover for the electrolysis bin 300, and the accommodating cavity 102 can collect the leaked electrolyte to prevent the electrolyte from contacting other equipment, thereby improving the reliability of the electrolysis oxygen removal device 40.

[0043] Referring to Figure 3 , in some embodiments, the cover shell 100 can also include a front shell 110 and a rear shell 120. The front shell 110 and the rear shell 120 are coupled to form the accommodating cavity 102, which simplifies the assembly process of the electrolysis oxygen removal device 40.

[0044] Referring to Figure 3 and Figure 4In this embodiment, the front shell 110 and the rear shell 120 can be connected together by fasteners, and the front shell 110 can be set close to the storage compartment of the refrigerator 1. The oxygen inlet of the electrolysis chamber 300 can also be set towards the front shell 110 so that the air in the storage compartment passes through the front shell 110 and enters the accommodating cavity 102, thereby entering the electrolysis chamber 300 through the cathode plate set at the oxygen inlet.

[0045] See Figure 5 and Figure 6 , Figure 6 This is a schematic diagram of the front housing 110 in an electrolytic deoxygenation device 40 according to an embodiment of the present invention. In some specific embodiments, the front housing 110 may further include a front panel 112, a front side panel, and a rear panel 116. The front side panel is formed on the periphery of the front panel 112 and extends toward the rear housing 120. The front side panel also includes a bottom plate 114d formed on the lower edge of the front panel 112 and two front side panels formed on both sides of the front panel 112. The bottom plate 114d is used to form the bottom wall of the cover 100. The rear panel 116 is formed at the end of the bottom plate 114d and extends upward, and both ends of the rear panel 116 are respectively connected to the bottom of the two front side panels.

[0046] See Figure 6 Specifically, the front panel 112 is generally square and vertically arranged. The front side panel can be composed of a bottom plate 114d formed at the lower edge of the front panel 112, a front top plate 114a formed at the upper edge of the front, and two front side plates formed at the two side edges of the front panel 112 (for ease of description, the two front side plates can be the left front side plate 114b and the right front side plate 114c respectively). The front top plate 114a, the left front side plate 114b, the bottom plate 114d and the right front side plate 114c are connected in sequence.

[0047] The rear panel 116 is formed at the end of the bottom plate 114d and extends upward. The left and right ends of the rear panel 116 can be connected to the left front side plate 114b and the right front side plate 114c respectively. Therefore, the rear panel 116, the bottom plate 114d, the left front side plate 114b, the right front side plate 114c and the front panel 112 form a water collection area at the bottom of the accommodating cavity 102. In this way, once the electrolyte in the electrolysis chamber 300 leaks, the electrolyte can be collected in this water collection area to prevent further leakage of the electrolyte and facilitate subsequent discharge.

[0048] In this embodiment, since the bottom plate 114d can form the bottom wall of the cover 100, that is, the bottom plate 114d protrudes closer to the rear shell 120 than other front side panels, there is no installation gap on the bottom wall of the cover 100 after the front shell 110 and the rear shell 120 are fastened together, thus avoiding the risk of secondary leakage of electrolyte.

[0049] See Figure 5 and Figure 7, Figure 7 This is a schematic diagram of the rear housing 120 in an electrolytic deoxygenation device 40 according to an embodiment of the present invention. Further, the rear housing 120 may also include a rear panel 122 and a rear side panel. The rear panel 122 is opposite to the front panel 112. The rear side panel is formed on all the peripheries of the rear panel 122 except for the lower edge and extends toward the front housing 110. The lower edge of the rear panel 122 is in contact with the upper edge of the rear side panel 116, and the rear side panel is in contact with the front side panel.

[0050] Combination Figure 6 and Figure 7 Specifically, the rear panel 122 can be roughly square and is vertically arranged opposite to the front panel 112. The rear side panel can be composed of a left rear side panel 124a, a rear top panel 124b, and a right rear side panel 124c connected end to end. When the front shell 110 and the rear shell 120 are engaged, the lower edge of the rear panel 122 is aligned with the upper edge of the rear side panel 116 to form the rear wall of the cover 100. The left rear side panel 124a is aligned with the left front side panel 114b of the front side panel to form the left wall of the cover 100. The right rear side panel 124c is aligned with the right front side panel 114c to form the right wall of the cover 100. The rear top panel 124b is aligned with the front top panel 114a to form the top wall of the cover 100.

[0051] See Figure 5 and Figure 7 In some embodiments, the rear panel 122 has a first overlap 122a at its lower edge for abutting against the inner surface of the rear panel 116, and / or the rear panel has a second overlap 124d at its end for abutting against the inner surface of the front panel.

[0052] The aforementioned "inner surface" can be understood as the side of the rear panel 116 and the front panel facing the receiving cavity 102. When the front shell 110 and the rear shell 120 are fastened together, the first overlapping part 122a abuts against the inner surface of the rear panel 116, and the first overlapping part 122a abuts against the inner surface of the front panel. This increases the stability of the joint and improves the sealing between the front shell 110 and the rear shell 120.

[0053] In some embodiments, a first sealing layer (not shown in the figure) is provided at the junction of the lower edge of the rear panel 122 and the upper edge of the rear bulkhead 116, and / or a second sealing layer (not shown in the figure) is provided at the junction of the rear bulkhead and the front bulkhead.

[0054] The first and second sealing layers can be sealant, which further enhances the stability and sealing of the front shell 110 and the rear shell 120 when they are fastened together.

[0055] See Figure 3 and Figure 4In some embodiments, the rear panel 116 has a drain hole 116a for discharging the electrolyte collected in the accommodating cavity 102.

[0056] Specifically, the refrigerator 1 may also include a waste liquid tank 60 for receiving the electrolyte collected in the accommodating cavity 102. A waste discharge hole 116a is provided on the rear panel 116 and is connected to the water collection area. The waste discharge hole 116a is connected to the waste liquid tank 60 through a drain pipe 62 so as to discharge the electrolyte collected in the water collection area into the waste liquid tank 60 for unified treatment.

[0057] See Figure 4 and Figure 5 In some embodiments, the front panel 112 has an opening 118. The electrolytic deoxygenation device 40 may also include a cooling condensate plate 210, which is disposed in the accommodating cavity 102 and located at the opening 118. The cooling condensate plate 210 has multiple air inlets 212 to allow external air to enter the accommodating cavity 102 and thus enter the electrolysis chamber 300.

[0058] Furthermore, the electrolytic deoxygenation device 40 may also include a cold source plate 230, which is exposed to the outside of the housing 100 and connected to a cooling condensation plate 210, configured to conduct cooling energy to the cooling condensation plate 210 so as to condense the water vapor flowing on it.

[0059] Specifically, the electrolytic deoxygenation device 40 can be installed on the rear wall of the inner liner or drawer body, and the cold source plate 230 can be installed behind the cover 100 (e.g., Figure 5 (As shown). For refrigerator 1, the cooling chamber used to provide cooling capacity is generally located at the rear of refrigerator 1, so that the cold source plate 230 can be closer to the cooling chamber in order to absorb the cooling capacity of the cooling chamber.

[0060] The cold source plate 230 can also be connected to the cooling condensation plate 210 via the connecting plate 220. The cooling condensation plate 210, the connecting plate 220 and the cold source plate 230 can also be an integral plate made of a metal material with good thermal conductivity (such as aluminum, copper, etc.), which can improve the cooling effect of the cold source plate 230 to the cooling condensation plate 210.

[0061] The inventors realized that the electrochemical reaction in the electrolysis chamber 300 often generates a large amount of heat, and the local temperature will rise accordingly. As a result, the water in the electrolyte may be heated and evaporated by this heat. Since the storage chamber and the containment cavity 102 are connected through the air inlet 212, the evaporated water may also enter the storage chamber, causing the humidity in the storage chamber to rise and affecting the humidity control of the storage chamber. Furthermore, water vapor is very easy to condense when it enters the storage chamber and encounters cold. As time goes by, in the relatively sealed storage chamber, the condensation will continue to intensify, eventually leading to the accumulation of a large amount of liquid water, and even condensation into frost, which will affect the quality of food (accelerating mold, rot, etc.).

[0062] To overcome the above problems, in the electrolytic deoxygenation device 40 of this embodiment, the cooling condensation plate 210 can also absorb the cold energy on the cold source plate 230 to maintain a certain low temperature. In this way, the water vapor generated in the electrolysis chamber 300 is recondensed when it flows through the cooling condensation plate 210, which reduces the amount of water vapor entering the storage room, effectively controls the humidity of the storage room, and reduces the possibility of frost formation in the storage room.

[0063] Furthermore, as mentioned earlier, the electrochemical reaction within the electrolysis chamber 300 often generates a large amount of heat, causing the temperature of the containment cavity 102 to be higher than that of the storage room. This heat may then be transferred to the storage room via convection, causing the temperature of the storage room to rise, which is detrimental to temperature control. However, since the cooling condensation plate 210 in this embodiment maintains a certain low temperature, the air in the containment cavity 102 is cooled upon contact with the cooling condensation plate 210. In other words, the heat generated by the electrolysis chamber 300 is absorbed by the cooling condensation plate 210, reducing the impact of the heat generated by the electrolysis chamber 300 on the storage room.

[0064] See Figure 8 , Figure 8 yes Figure 5 Enlarged view of section A. The cooling condensation plate 210 is provided with a shielding part 130 at each air inlet 212. Each shielding part 130 arches away from the cooling condensation plate 210 and is configured to cover at least a portion of an air inlet 212 on the projection of the cooling condensation plate 210 to prevent water vapor escaping from the electrolysis chamber 300 from being discharged from the air inlet 212.

[0065] That is, the shielding part 130 can block the air inlet 212 from facing the space. In this way, when the water vapor escaping from the electrolysis chamber 300 passes through the air inlet 212, it will inevitably come into contact with the shielding part 130. After encountering the shielding part 130, the water vapor is cooled and condensed, further reducing the amount of water vapor discharged from the accommodating cavity 102.

[0066] Furthermore, each shield 130 opens downwards, so that water condensed on the shield 130 can fall outwards under the action of gravity and enter the water collection area.

[0067] Furthermore, each shield 130 can also be provided on the air inlet surface of the cooling condensation plate 210 facing the storage room. Due to the stronger air flow, the air can bypass the shield 130 and enter the air inlet 212 during the flow from the storage room to the receiving cavity 102, and then enter the receiving cavity 102. Therefore, the shield 130 has less impact on the air that is about to enter the receiving cavity 102.

[0068] In addition, since the cooling condensate plate 210 can condense the water vapor in the receiving cavity 102, the condensed water can flow into the water collection area along the cooling condensate plate 210. That is, the water collection area can collect condensed water and electrolyte at the same time. Therefore, the height of the waste discharge hole 116a also needs to take into account the daily storage water level of condensed water. That is, the height of the waste discharge hole 116a should be higher than the daily storage water level of condensed water. This can prevent the condensed water from being discharged into the waste liquid tank 60 together and prevent the condensed water from occupying the volume of the waste liquid tank 60.

[0069] Therefore, those skilled in the art should recognize that although numerous exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Thus, the scope of the present invention should be understood and construed as covering all such other variations or modifications.
