[0027] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] See Figure 1 , Figure 1 This is a schematic diagram of a refrigerator 1 according to an embodiment of the present invention. The present invention provides a refrigerator 1, which generally includes a cabinet 10 and a door 20.

[0029] The refrigerator body 10 may include an outer shell and multiple inner liners. The outer shell is located on the outermost side of the overall refrigerator 1 to protect the entire refrigerator 1. The multiple inner liners are enclosed by the outer shell, and the space between them is filled with insulation material (forming a foam layer) to reduce heat loss from the inner liners. Each inner liner may define a forward-opening storage compartment, and the storage compartment may be configured as a refrigerator compartment, freezer compartment, variable temperature compartment, etc. The specific number and function of the storage compartments can be configured according to pre-defined needs.

[0030] The door 20 is movably disposed at the front of the inner liner to open and close the storage compartment of the inner liner. For example, the door 20 can be hinged to one side of the front of the box 10 and the storage compartment can be opened and closed by pivoting.

[0031] The refrigerator 1 may also include a drawer assembly 30, which may further include a drawer body that is pullable into the storage compartment for the user to retrieve items.

[0032] In some embodiments, the refrigerator 1 may also include an electrolytic deoxygenation device 40, which may be disposed on the inner liner or drawer assembly 30. The device separates oxygen from the air flowing over it through an electrolytic reaction and leaves nitrogen in the storage compartment of the inner liner or the drawer body to achieve food preservation.

[0033] See Figure 2 , Figure 2 This is a schematic diagram showing the installation relationship between the refrigerator body 10 and the electrolytic oxygen removal device 40 in a refrigerator 1 according to an embodiment of the present invention, wherein the outer shell and foam layer of the refrigerator body 10 are hidden. Figure 2 The diagram shows the electrolytic deoxygenation device 40 installed on the rear wall of the storage compartment. However, the electrolytic deoxygenation device 40 is not limited to this; it can also be installed on the side wall, top wall, or bottom wall of the storage compartment, or on the rear wall, side wall, or bottom wall of the drawer body. In short, those skilled in the art, after understanding the technical solution of this embodiment, can configure the electrolytic deoxygenation device 40 according to actual conditions, and not all examples will be listed here.

[0034] See Figures 3 to 5 , Figure 3 This is an exploded view of the electrolytic oxygen removal device 40 in a refrigerator 1 according to an embodiment of the present invention. Figure 4 This is a cross-sectional view of the electrolytic oxygen removal device 40 in a refrigerator 1 according to an embodiment of the present invention. Figure 5 yes Figure 4 Enlarged view of section A.

[0035] In some embodiments, the electrolytic deoxygenation device 40 may further include a housing 100, a cooling condensation plate 210, and an electrolysis chamber 300. The housing 100 has a receiving cavity 140, and one side of the housing 100 has an opening 112. The cooling condensation plate 210 is disposed in the receiving cavity 140 and located at the opening 112. The electrolysis chamber 300 is disposed in the receiving cavity 140 to separate oxygen from the air flowing through it through an electrochemical reaction. The cooling condensation plate 210 has a plurality of air inlets 212, which are configured to allow external air to enter the receiving cavity 140 and thus enter the electrolysis chamber 300.

[0036] In some specific embodiments, the inner liner or drawer body has multiple connecting holes (not shown in the figure). The electrolytic deoxygenation device 40 can be set on the outside of the inner liner or drawer body, and the air inlet 212 on the cooling condensation plate 210 is opposite to the connecting holes. In this way, the air in the storage room can enter the accommodating cavity 140 through the connecting holes and the air inlet 212 in sequence, and then enter the electrolysis chamber 300 to carry out electrochemical reaction.

[0037] In some other specific embodiments, the inner liner or drawer body may also have a snap-fit ​​hole (not shown in the figure), the cover 100 of the electrolytic deoxygenation device 40 can be snapped into the snap-fit ​​hole, and the cooling condensation plate 210 is directly exposed in the storage room, so that the air in the storage room can directly enter the accommodating cavity 140 through the air inlet 212.

[0038] Since the electrolysis chamber 300 is located inside the accommodating cavity 140 of the cover 100, the cover 100 can protect the electrolysis chamber 300 from the influence of the external environment and prevent items in the storage room from scratching the electrolysis deoxygenation device 40, thereby damaging the structure of the electrolysis deoxygenation device 40 and its installation structure.

[0039] In some embodiments, one side of the electrolysis chamber 300 may be opened to form an oxygen inlet. The oxygen inlet may be provided with a cathode plate with waterproof and breathable functions so that air can enter the interior of the electrolysis chamber 300 through the cathode plate and prevent the electrolyte in the electrolysis chamber 300 from flowing out. That is, in this embodiment, the cathode plate may be at least part of one of the walls of the electrolysis chamber 300, and in order to improve the air intake efficiency, the cathode plate may be arranged facing the storage room.

[0040] The cathode plate can be loaded with the negative electrode of an external power source. Air from the storage space enters the electrolysis chamber at 300°C and undergoes a reduction reaction, generating negative ions: O₂ + 2H₂O + 4e⁻. - →4OH - .

[0041] The electrolysis chamber 300 can also hold electrolyte. The anode plate can be placed inside the electrolysis chamber 300 and connected to the positive terminal of an external power source. The negative ions generated at the cathode plate flow to the anode plate under the influence of the electric field and undergo an oxidation reaction on the anode plate to generate oxygen, i.e., 4OH-. - →O2 + 2H2O + 4e - This allows oxygen in the air to be separated and released, reducing the oxygen content in the storage room.

[0042] As can be seen from the above, the side of the electrolysis chamber 300 facing the storage room can be a waterproof and breathable cathode plate. When the electrolysis chamber 300 is installed in the accommodating cavity 140 of the cover 100, it can further protect the waterproof and breathable cathode plate and prevent the cathode plate from being punctured by external objects, which could lead to electrolyte leakage and an accident.

[0043] Combination Figure 3 , Figure 4 and Figure 6 , Figure 6This is a schematic diagram of a cooling condensation plate 210, a connecting plate 220, and a cold source plate 230 in an electrolytic deoxygenation device 40 according to an embodiment of the present invention. In some embodiments, the electrolytic deoxygenation device 40 may further include a cold source plate 230, which is exposed outside the housing 100 and connected to the cooling condensation plate 210, configured to conduct cooling energy to the cooling condensation plate 210 to condense water vapor flowing thereon.

[0044] 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 4 (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.

[0045] 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.

[0046] 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 140 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.).

[0047] 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.

[0048] 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 140 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 140 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.

[0049] In summary, the cooling condensation plate 210 in the electrolytic deoxygenation device 40 of this embodiment has the following functions and technical effects:

[0050] 1. The cooling condensation plate 210 can be used as part of the cover 100. The air inlet 212 on it connects the storage chamber and the accommodating cavity 140. This can prevent the electrolysis chamber 300 inside the cover 100 from rubbing against the items in the storage chamber and improve the stability of the electrolytic deoxygenation device 40.

[0051] Second, the cooling condensation plate 210 can be provided with a certain amount of cooling by the cold source plate 230, so that it can maintain a certain low temperature. In this way, the water vapor generated by the electrolysis chamber 300 is cooled when it encounters the cooling condensation plate 210, which reduces the amount of water vapor entering the storage room and reduces the possibility of frost formation in the storage room.

[0052] Third, since the cooling condensation plate 210 maintains a certain low temperature, it can also absorb the heat generated when the electrolysis chamber 300 is working, preventing excessive heat from entering the storage room and causing the temperature of the storage room to rise, thus ensuring the stability of the temperature control of the storage room.

[0053] See Figure 3 , Figure 4 and Figure 7 , Figure 7 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 embodiments, the housing 100 may further include a front housing 110 and a rear housing 120, which are engaged to form a receiving cavity 140. An opening 112 is formed in the front housing 110, and the bottom of the front housing 110 also has a base 114 to receive condensate falling from the cooling condensate plate 210.

[0054] In this embodiment, the front shell 110 and the rear shell 120 can be connected together by fasteners, forming an internal accommodating cavity 140. An opening 112 is formed in the front shell 110. Since the cooling condensation plate 210 is located at the opening 112, the front shell 110 is closer to the storage compartment than the rear shell 120.

[0055] The bottom of the front shell 110 is provided with a base 114, the bottom wall of which can serve as the bottom wall of the cover 100. The bottom wall of the base 114 bends upward on the side near the rear shell 120 to form a water collection area below the accommodating cavity 140. In this way, when water vapor encounters the cooling condensation plate 210, it is condensed into liquid water droplets and can flow into the water collection area under the action of gravity so that the collected liquid water can be discharged later.

[0056] See Figure 4 and Figure 7 Furthermore, the front shell 110 has a water-retaining flange 116 at the lower edge of the opening 112 that extends away from the front shell 110 and tilts upward.

[0057] Since the cooling condensation plate 210 is located at the opening 112, when the water droplets condensed on it fall downwards, they may be affected by some objective factors (such as airflow) and will not flow downwards along the cooling condensation plate 210, thus failing to flow successfully into the water collection area of ​​the base 114. The water-blocking flange 116 is located at the lower edge of the opening 112 and extends away from the front shell 110 and upwards at an angle. In this way, the water-blocking flange 116 widens the area for receiving water droplets in the horizontal direction, ensuring that the water droplets flow into the interior of the front shell 110 and then into the water collection area.

[0058] See Figure 4 and Figure 7 Furthermore, a plurality of protrusions 118 are formed on the inner side of the front shell 110 along the circumferential direction of the opening 112, so that a flow gap is formed between the inner side of the cooling condensation plate 210 and the front shell 110, so that water on the air inlet surface of the cooling condensation plate 210 flows into the base 114 through the flow gap.

[0059] When the cooling condensation plate 210 cools water vapor, condensation may occur on both the air inlet side facing the storage compartment and the air outlet side facing the receiving cavity 140. If the cooling condensation plate 210 is placed tightly against the inside of the front shell 110, water droplets on the air inlet side of the cooling condensation plate 210 will have difficulty entering the base 114 due to the obstruction of the cooling condensation plate 210 itself. However, in this embodiment, the inside of the front shell 110 is provided with multiple protrusions 118 around the opening 112. When the cooling condensation plate 210 is placed at the opening 112, a flow gap can be formed under the support of the multiple protrusions 118. That is, a flow space is formed between the air inlet side of the cooling condensation plate 210 and the inside of the front shell 110. In this way, water droplets formed on the air inlet side of the cooling condensation plate 210 can pass through the flow gap and enter the base 114.

[0060] See Figure 7Furthermore, the protrusion 118 located below the opening 112 extends vertically from the inside of the water-blocking flange 116 to the bottom wall of the base 114, so as to guide the water on the water-blocking flange 116 into the base 114. This allows the protrusion 118 below the opening 112 to have a guiding effect and accelerate the condensation to slide off.

[0061] See Figure 4 and Figure 5 In some embodiments, the cooling condensate plate 210 is provided with a shielding portion 130 at each air inlet 212, each shielding portion 130 arching away from the cooling condensate plate 210, and each shielding portion 130 is configured to cover at least a portion of an air inlet 212 on the projection of the cooling condensate plate 210 to prevent water vapor escaping from the electrolysis chamber 300 from being discharged from the air inlet 212.

[0062] 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 140.

[0063] 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 of ​​the base 114.

[0064] 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 140, and then enter the receiving cavity 140. Therefore, the shield 130 has less impact on the air that is about to enter the receiving cavity 140.

[0065] Furthermore, since the shielding part 130 arches away from the cooling condensation plate 210 and can be provided on the air inlet surface of the cooling condensation plate 210, and the front shell 110 has an outwardly extending water-retaining flange 116, the water-retaining flange 116 is also used to catch water droplets dripping from the shielding part 130.

[0066] See Figure 3 and Figure 4 In some embodiments, the electrolytic deoxygenation device 40 may further include a dehumidifier 400 disposed in the accommodating cavity 140 and including a water-absorbing plate 410 disposed at the bottom of the accommodating cavity 140 and an evaporating plate 420 extending upward from one end of the water-absorbing plate 410, so as to absorb water collected at the bottom of the electrolysis chamber 300 by the water-absorbing plate 410 and transfer it to the evaporating plate 420 for evaporation.

[0067] Furthermore, the evaporator plate 420 can also be opposite to the rear shell 120, and the rear shell 120 is provided with multiple exhaust holes 126. The water vapor evaporated on the evaporator plate 420 can be discharged from the accommodating cavity 140 through the multiple exhaust holes 126 to complete the dehumidification.

[0068] 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.
