Description

Technical Field

[0001] The invention belongs to the technical field of food preservation, and specifically provides an atmosphere-adjusting device and preservation equipment having the same. Background Art

[0002] Currently, some refrigerators are equipped with low-oxygen spaces and atmosphere-conditioning devices, so that the atmosphere-conditioning devices consume oxygen in the low-oxygen space through electrochemical reactions, reduce the oxygen content in the low-oxygen space, and increase the shelf life of food in the low-oxygen space.

[0003] The existing gas conditioning device generally includes a cathode, an anode and an electrolyte filled between the cathode and the anode. The gas conditioning device contacts the air in the hypoxic space through the cathode, so that the oxygen undergoes a reduction reaction at the cathode, namely: O2+2H2O+4e - →4OH - . An oxidation reaction occurs at the anode, and oxygen is generated, namely: 4OH - →O2+2H2O+4e - .

[0004] In the process of electrochemical reaction in existing gas conditioning devices, the anode is generally immersed in electrolyte, so that oxygen at the anode forms bubbles in the electrolyte. The bubbles will carry a small amount of electrolyte in the process of floating up, so that the electrolyte will be discharged from the gas conditioning device together with the oxygen. Since the electrolyte is usually alkaline or acidic, when the electrolyte enters the refrigerator together with oxygen, it will not only contaminate the food in the refrigerator, but also corrode the electronic components inside the refrigerator, affecting the service life of the refrigerator. Summary of the invention

[0005] One object of the present invention is to solve the problem that oxygen discharged from the existing gas conditioning device carries electrolyte.

[0006] A further object of the present invention is to avoid replenishing water separately for the air washing chamber of the gas conditioning device.

[0007] A further object of the present invention is to make the structure of the gas conditioning device more compact so as to reduce the spatial size of the gas conditioning device.

[0008] To achieve the above object, the present invention provides an atmosphere control device in a first aspect, comprising:

[0009] an electrolytic deoxidation unit, used to consume oxygen outside the electrolytic deoxidation device through an electrochemical reaction;

[0014] Optionally, the width of the protrusion is less than half of the width of the main body.

[0015] Optionally, the anode terminal and the cathode terminal of the electrolytic deoxidation unit extend to a side of the main body close to the protruding portion, and are located on a side away from the protruding portion in the width direction of the main body.

[0016] Optionally, the liquid replenishing port is located toward a side of the protruding portion facing the anode terminal and the cathode terminal, and is located above the anode terminal and the cathode terminal in a vertical direction.

[0017] Optionally, a first liquid passage connecting the liquid replenishment chamber and the reaction chamber is provided on the side wall between the liquid replenishment chamber and the reaction chamber, and a second liquid passage connecting the liquid replenishment chamber and the gas washing chamber is provided on the side wall between the liquid replenishment chamber and the gas washing chamber.

[0018] Optionally, the first liquid passage port is located at the top of the liquid infusion chamber and is lower than the liquid infusion port; and / or, the second liquid passage port is located at the bottom of the liquid infusion chamber.

[0019] Optionally, a first air inlet hole is provided on the side wall at the top of the liquid replenishment chamber, a second air inlet hole is provided on the side wall at the bottom of the air washing chamber, and the gas conditioning device further includes an air inlet pipe connecting the first air inlet hole with the second air inlet hole.

[0020] Optionally, the lowest position of the first air inlet is higher than the lowest position of the first liquid outlet; and / or the highest position of the second air inlet is higher than the highest position of the second liquid outlet.

[0021] Optionally, the height of the exhaust port is not lower than the height of the first air ducting hole.

[0022] Optionally, the electrolytic deoxidation unit includes a cathode plate and an anode plate, the anode plate is arranged in the reaction chamber and located below the first liquid outlet, and the cathode plate is located below the anode plate; the cathode plate is used to consume oxygen through an electrochemical reaction, and the anode plate is used to provide reactants to the cathode plate and generate oxygen through an electrochemical reaction.

[0023] Optionally, the container comprises a bottom shell and a top shell which are sealed together, and the bottom shell and the top shell jointly define the reaction chamber, the liquid replenishment chamber and the gas washing chamber.

[0024] Optionally, at least one mounting boss is respectively provided on both sides of the bottom shell in the width direction thereof.

[0025] Optionally, the gas-conditioning device further includes a liquid level sensor for detecting the liquid level height in the reaction chamber; and / or, the gas-conditioning device further includes a one-way valve arranged at the liquid infusion port or fluidly connected to the liquid infusion port, the one-way valve being configured to only allow liquid to flow from the outside of the container to the liquid infusion chamber.

[0026] In a second aspect, the present invention provides a fresh-keeping device, comprising:

[0027] The box body defines a low oxygen space;

[0029] Optionally, the box body further defines a high-oxygen space, and the atmosphere control device is further configured to supply oxygen to the high-oxygen space; and / or, the fresh-keeping device is a refrigerator.

[0030] Based on the foregoing description, those skilled in the art can understand that, in the aforementioned technical solution of the present invention, the container is defined to define a reaction chamber, a liquid replenishment chamber and a gas washing chamber distributed in a horizontal direction, and the liquid replenishment chamber is connected to the reaction chamber through its top and to the gas washing chamber through its bottom; an exhaust port is provided at the top of the gas washing chamber, and the gas washing chamber is connected to the top of the liquid replenishment chamber through its bottom, so that the oxygen generated in the reaction chamber first flows to the top of the liquid replenishment chamber, then flows to the bottom of the gas washing chamber, and then is discharged from the exhaust port. When oxygen flows through the gas washing chamber, it flows from bottom to top, and thus the electrolyte carried by the oxygen is absorbed by the liquid in the gas washing chamber, thereby preventing the electrolyte from flowing out of the gas conditioning device with the oxygen.

[0031] Furthermore, since the liquid replenishing chamber is connected to the reaction chamber and the gas washing chamber respectively, when the gas conditioning device replenishes water through the liquid replenishing port, the water in the liquid replenishing chamber can flow to the reaction chamber and the gas washing chamber at the same time, avoiding the tedious operation of replenishing water for the gas washing chamber alone.

[0032] Furthermore, since the container simultaneously defines the reaction chamber, the liquid replenishment chamber and the gas washing chamber, the overall structure of the gas conditioning device is more compact, and the spatial size of the gas conditioning device is reduced.

[0045] It should be understood by those skilled in the art that the embodiments described below are only some embodiments of the present invention, rather than all embodiments of the present invention, and these embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0046] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0047] Furthermore, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components.

[0049] like Figure 1As shown, in some embodiments of the present invention, the gas conditioning device 100 includes a container 110 and an electrolytic deoxidation unit 120. The electrolytic deoxidation unit 120 is used to consume oxygen outside the electrolytic deoxidation device through an electrochemical reaction. The container 110 defines a reaction chamber 1101, a liquid replenishment chamber 1102, and a gas washing chamber 1103 distributed in a horizontal direction. The reaction chamber 1101 is provided with the electrolytic deoxidation unit 120. The liquid replenishment chamber 1102 has a liquid replenishment port 1104, and the liquid replenishment chamber 1102 is connected to the reaction chamber 1101 through its top and to the gas washing chamber 1103 through its bottom. The top of the gas washing chamber 1103 is provided with an exhaust port 1105, and the gas washing chamber 1103 is connected to the top of the liquid replenishment chamber 1102 through its bottom.

[0050] Continue reading below Figures 1 to 8 The gas conditioning device in some embodiments of the present invention is described in detail. Figure 1 is a structural exploded view of the gas conditioning device in some embodiments of the present invention, Figure 2 is a first isometric view of the gas conditioning device in some embodiments of the present invention, Figure 3 is a second isometric view of the gas conditioning device in some embodiments of the present invention, Figure 4 is a third isometric view of the gas conditioning device in some embodiments of the present invention, Figure 5 yes Figure 2 The cross-sectional view of the gas conditioning device along the AA direction, Figure 6 yes Figure 2 The cross-sectional view of the central gas conditioning device along the BB direction, Figure 7 yes Figure 2 Cross-sectional view of the central gas conditioning device along the CC direction, Figure 8 yes Figure 2 Cross-sectional view of the central gas conditioning device along the DD direction.

[0051] like Figure 1 As shown, in some embodiments of the present invention, the electrolytic deoxidation unit 120 includes an anode terminal 121 and a cathode terminal 122, which extend from the inside of the container 110 to the outside of the container 110 to connect to an external power source.

[0052] Continue reading Figure 1 In some embodiments of the present invention, the electrolytic deoxidation unit 120 further includes an anode plate 123 and a cathode plate 124, wherein the anode plate 123 is electrically connected to the anode terminal 121, and the cathode plate 124 is electrically connected to the cathode terminal 122. Optionally, the anode plate 123 and the anode terminal 121 are fixedly connected together by welding, riveting or crimping, and the cathode plate 124 and the cathode terminal 122 are fixedly connected together by welding, riveting or crimping.

[0053] In the present invention, the cathode plate 124 is used to consume oxygen through an electrochemical reaction, that is, a reduction reaction occurs: O2+2H2O+4e - →4OH - The anode plate 123 is used to provide reactants to the cathode plate 124 through an electrochemical reaction and generate oxygen, that is, an oxidation reaction occurs: 4OH - →O2+2H2O+4e - .

[0054] Furthermore, the cathode plate 124 may include a catalyst layer, a first waterproof and breathable layer, a conductive layer, and a second waterproof and breathable layer, which are sequentially arranged. The catalyst layer may use a precious metal or rare metal catalyst, such as metal platinum, metal gold, metal silver, metal manganese, or metal rubidium. The first waterproof and breathable layer and the second waterproof and breathable layer may be waterproof and breathable membranes, so that the electrolyte cannot seep out of the reaction chamber 1101, while air can pass through the first waterproof and breathable layer and the second waterproof and breathable layer into the reaction chamber 1101. The conductive layer may be 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 support strength.

[0055] like Figure 1 As shown, in some embodiments of the present invention, the container 110 may include a bottom shell 111 and a top shell 112 sealed together, and the bottom shell 111 and the top shell 112 jointly define a reaction chamber 1101, a liquid replenishment chamber 1102 and a gas washing chamber 1103.

[0056] The bottom shell 111 and the top shell 112 may be sealed together by hot-melt, or by clamping a sealing ring, or by any other feasible method.

[0057] from Figure 1 As can be seen in the figure, at least one mounting boss 1111 is respectively provided on both sides of the bottom shell 111 in the width direction thereof, so that the air conditioning device 100 can be fixed to a target device, such as a refrigerator, through the mounting boss 1111.

[0058] Continue reading Figure 1 In some embodiments of the present invention, an opening 1112 is further provided on the bottom wall of the bottom shell 111, and a cathode plate 124 is provided at the opening 1112 and covers the opening 1112, so that the cathode plate 124 constitutes a side wall of the reaction chamber 1101. The cathode plate 124 is used to allow oxygen outside the gas conditioning device 100 to enter the reaction chamber 1101 through the cathode plate 124, and prevent the liquid in the reaction chamber 1101 from flowing out through the cathode plate 124.

[0059] from Figure 1It can also be seen that a support frame 1113 is provided inside the bottom shell 111, and the support frame 1113 is used to support the anode plate 123. The support frame 1113 is fixedly connected to the bottom shell 111 or made integrally. Optionally, the support frame 1113 is snapped together with the bottom shell 111, or is welded to the bottom shell 111 or connected together with screws.

[0060] Furthermore, the anode plate 123 can be fixedly mounted on the support frame 1113 and fixedly connected to the support frame 1113. For example, the anode plate 123 can be fixed to the support frame 1113 by screws.

[0061] from Figure 1 As can be seen in the figure, the bottom shell 111 and the top shell 112 jointly define the reaction chamber 1101, the liquid replenishment chamber 1102 and the gas washing chamber 1103.

[0062] from Figure 1 It can also be seen that the container 110 is provided with a liquid inlet 1104, an exhaust port 1105, a first air inlet 1106 and a second air inlet 1107. The liquid inlet 1104 and the first air inlet 1106 are formed on the side wall at the top of the liquid inlet chamber 1102, the exhaust port 1105 is formed on the side wall at the top of the air washing chamber 1103, and the second air inlet 1107 is formed on the side wall at the bottom of the air washing chamber 1103.

[0063] In the description of the present invention, both "mouth" and "hole" are channels with a certain depth.

[0064] Further, from Figure 1 It can also be seen that the gas conditioning device 100 further includes an air duct 130 connecting the first air duct 1106 with the second air duct 1107 .

[0065] like Figures 1 to 4 As shown, the side walls of the liquid inlet 1104, the exhaust port 1105, the first air inlet hole 1106 and the second air inlet hole 1107 can extend outward to form a joint. The joints corresponding to the first air inlet hole 1106 and the second air inlet hole 1107 are respectively plugged into the air inlet pipe 130.

[0066] In addition, those skilled in the art may also, as needed, only make the liquid inlet 1104, the exhaust port 1105, the first air inlet hole 1106 and the second air inlet hole 1107 pass through the side wall of the container 110 respectively, and configure a connector for each of the liquid inlet 1104, the exhaust port 1105, the first air inlet hole 1106 and the second air inlet hole 1107.

[0067] In addition, in other embodiments of the present invention, those skilled in the art may also provide a connecting channel on the side wall of the container 110 as needed, and connect the two ends of the connecting channel to the first air inlet hole 1106 and the second air inlet hole 1107 respectively.

[0068] from Figure 1 As can be seen in the figure, the liquid replenishment chamber 1102 and the gas washing chamber 1103 are located on one side of the length direction of the reaction chamber 1101, and the liquid replenishment chamber 1102 and the gas washing chamber 1103 are arranged adjacent to each other. Further, the liquid replenishment chamber 1102 and the gas washing chamber 1103 are distributed along the width direction of the reaction chamber 1101.

[0069] In addition, those skilled in the art may also arrange the liquid replenishment chamber 1102 and the gas washing chamber 1103 in any other feasible form as needed, such as arranging the liquid replenishment chamber 1102 and the gas washing chamber 1103 on one side of the reaction chamber 1101 in the width direction.

[0070] like Figures 2 to 4 As shown, in some embodiments of the present invention, the container 110 includes a body portion 110 a defining a reaction chamber 1101 and a protruding portion 110 b defining a liquid replenishing chamber 1102 and a gas washing chamber 1103 .

[0071] from Figures 2 to 4 As can be seen in the figure, the width of the protrusion 110b is less than half the width of the body 110a. The anode terminal 121 and the cathode terminal 122 extend to the side of the body 110a close to the protrusion 110b and are located on the side away from the protrusion 110b in the width direction of the body 110a.

[0072] Furthermore, the liquid replenishing port 1104 is located toward the side of the protruding portion 110 b facing the anode terminal 121 and the cathode terminal 122 , and is located above the anode terminal 121 and the cathode terminal 122 in the vertical direction.

[0073] It is understood by those skilled in the art that the liquid replenishment chamber 1102 and the air washing chamber 1103 are as follows: Figures 1 to 4 The arrangement shown in FIG. 1 , the arrangement of the anode terminal 121 and the cathode terminal 122, and the liquid replenishing port 1104 are as shown in FIG. Figures 1 to 4 The orientation shown in the figure makes the overall structure of the atmosphere conditioning device 100 more compact, and effectively reduces the spatial size of the atmosphere conditioning device 100.

[0074] like Figures 5 to 7As shown, in some embodiments of the present invention, a first liquid-passing port 1108 is provided on the side wall between the liquid-replenishing chamber 1102 and the reaction chamber 1101 to connect the two, so that the liquid in the liquid-replenishing chamber 1102 flows to the reaction chamber 1101 through the first liquid-passing port 1108. A second liquid-passing port 1109 is provided on the side wall between the liquid-replenishing chamber 1102 and the gas-washing chamber 1103 to connect the two, so that the liquid in the liquid-replenishing chamber 1102 flows to the gas-washing chamber 1103 through the first liquid-passing port 1108.

[0075] The first liquid passage 1108 is located at the top of the liquid replenishing chamber 1102 and is lower than the liquid replenishing port 1104 , so as to ensure that the liquid in the liquid replenishing chamber 1102 can smoothly enter the reaction chamber 1101 .

[0076] The second liquid passage 1109 is located at the bottom of the liquid replenishing chamber 1102 , so that the liquid replenishing chamber 1102 and the gas washing chamber 1103 form a communicating structure, and thus the liquid in the liquid replenishing chamber 1102 enters the gas washing chamber 1103 .

[0077] Those skilled in the art will appreciate that the first liquid passage port 1108 is located at the top of the liquid replenishment chamber 1102 and is lower than the liquid replenishment port 1104, and the second liquid passage port 1109 is located at the bottom of the liquid replenishment chamber 1102, which can ensure that when the liquid replenishment chamber 1102 completes the liquid replenishment for the reaction chamber 1101, the liquid in the wash chamber 1103 has a sufficient height.

[0078] Refer to the following Figures 5 to 8 The height of each flow port / hole on the container 110 is described. Before that, it should be noted that Figures 5 to 8 The heights marked therein are all relative to the bottom surface of the container 110 .

[0079] like Figures 5 to 8 As shown, the height of the lowest position of the liquid replenishing port 1104 is recorded as h1, the height of the lowest position of the first liquid transfer port 1108 is recorded as h2, the height of the highest position of the second liquid transfer port 1109 is recorded as h3, the height of the lowest position of the first air inlet 1106 is recorded as h4, the height of the highest position of the second air inlet 1107 is recorded as h5, the height of the lowest position of the exhaust port 1105 is recorded as h6, and the height of the anode plate 123 is recorded as H.

[0080] from Figures 5 to 8 It can be seen that the height h1 of the liquid replenishing port 1104 is greater than the height h2 of the first liquid passing port 1108, and the height h2 of the first liquid passing port 1108 is greater than the height h3 of the second liquid passing port 1109, that is, h1>h2>h3. It can be understood by those skilled in the art that by making h1>h2>h3, it can be ensured that the liquid in the liquid replenishing chamber 1102 flows to the reaction chamber 1101 and the gas washing chamber 1103.

[0081] from Figures 5 to 8 It can be seen that the height h4 of the first air inlet 1106 is greater than the height h2 of the first liquid outlet 1108. Those skilled in the art can also ensure that the liquid in the liquid replenishing cavity 1102 does not flow out through the first air inlet 1106 by making h4>h2 as needed.

[0082] from Figures 5 to 8 It can be seen that the height h5 of the second air inlet 1107 is greater than the height h3 of the second liquid port 1109, that is, h5>h3. Those skilled in the art can also make the liquid pressure at the second air inlet 1107 greater than the liquid pressure at the second liquid port 1109 by making h5>h3 as needed, thereby ensuring that the oxygen entering the liquid replenishing chamber 1102 from the reaction chamber 1101 via the first liquid port 1108 can only enter the washing chamber 1103 through the path of the first air inlet 1106→air inlet pipe 130→second air inlet 1107, and will not enter the washing chamber 1103 through the second liquid port 1109. The specific principle is as follows:

[0083] like Figure 5 and Figure 6 As shown, a communicating vessel structure is formed between the liquid replenishing chamber 1102 and the air washing chamber 1103 through the second liquid passage 1109. For the convenience of description, the communicating vessel is referred to as the first communicating vessel. Another communicating vessel structure is formed between the liquid replenishing chamber 1102 and the air washing chamber 1103 through the first air inlet hole 1106, the air inlet pipe 130 and the second air inlet hole 1107. For the convenience of description, the communicating vessel is referred to as the second communicating vessel.

[0084] Those skilled in the art can understand that after the gas conditioning device 100 is filled with liquid, the liquid levels in the liquid filling chamber 1102, the air washing chamber 1103 and the air duct 130 are at the same height, and the transverse cross-section of the liquid filling chamber 1102 is much larger than the transverse cross-section of the air duct 130, resulting in the liquid level in the liquid filling chamber 1102 being much larger than the liquid level in the air duct 130, so the liquid in the liquid filling chamber 1102 is much more than the liquid in the air duct 130. Since the gas enters the air washing chamber 1103 from the liquid filling chamber 1102, it can only pass through the second liquid port 1109 and the air duct 130.

[0085] If there is no air duct 130, the liquid in the liquid replenishing chamber 1102 will enter the gas washing chamber 1103 through the second liquid passage port 1109. Since there is a lot of liquid in the liquid replenishing chamber 1102, when the liquid level in the liquid replenishing chamber 1102 does not drop to the second liquid passage port 1109, there will be more liquid in the gas washing chamber 1103 and it will flow out from the exhaust port 1105.

[0086] In the case where there is an air duct 130 and the height h5 of the second air duct hole 1107 is greater than the height h3 of the second liquid passage port 1109, when the liquid level in the liquid replenishing chamber 1102 drops to the height h3 of the second liquid passage port 1109, the gas in the liquid replenishing chamber 1102 can enter the gas washing chamber 1103 through the air duct 130.

[0087] Because part of the liquid in the liquid replenishing chamber 1102 will enter the gas washing chamber 1103 before the gas in the liquid replenishing chamber 1102 enters the gas washing chamber 1103, causing the liquid level in the gas washing chamber 1103 to rise, so in other embodiments of the present invention, those skilled in the art may also, as needed, make the height h5 of the second air inlet hole 1107 as high as possible, provided that the height h5 of the second air inlet hole 1107 is lower than the lowest liquid level in the gas washing chamber 1103.

[0088] Furthermore, although not shown in the figures, in some embodiments of the present invention, the gas conditioning device 100 may further include a liquid level sensor for detecting the liquid level height in the reaction chamber 1101 .

[0089] Exemplarily, the liquid level sensor is installed in the reaction chamber 1101 and is used to detect the maximum height and the minimum height of the liquid level in the reaction chamber 1101 .

[0090] Furthermore, although not shown in the figures, in some embodiments of the present invention, the gas control device 100 may also include a one-way valve disposed at the liquid infusion port 1104 or fluidly connected to the liquid infusion port 1104, and the one-way valve is configured to only allow liquid to flow from the outside of the container 110 to the liquid infusion chamber 1102.

[0091] Those skilled in the art will appreciate that the one-way valve can automatically close the liquid replenishing port 1104 after the liquid replenishing of the gas conditioning device 100 is completed, thereby preventing air from being discharged from the liquid replenishing port 1104 and affecting the gas washing function of the gas conditioning device 100 .

[0092] Refer to the following Figures 2 to 8 The following describes the liquid replenishment principle of the gas conditioning device 100 in some embodiments of the present invention.

[0093] First, the gas conditioning device 100 is connected to an external water source through the liquid replenishing port 1104, and the external water source is used to provide water for the gas conditioning device 100. The external water source includes a water storage box and a water pump, and the water pump is used to pump the water in the water storage box to the gas conditioning device 100.

[0094] When the liquid level sensor detects that the liquid level in the reaction chamber 1101 has dropped to the minimum height, the water pump transfers the water in the water storage box to the liquid replenishment chamber 1102. The water in the liquid replenishment chamber 1102 first enters the gas washing chamber 1103 through the second liquid port 1109. When the water in the liquid replenishment chamber 1102 rises to the first liquid port 1108, it enters the reaction chamber 1101 through the first liquid port 1108. When the liquid level sensor detects that the liquid level in the reaction chamber 1101 has reached the maximum height, the water pump stops working and stops replenishing water.

[0095] It should be noted that in order to prevent the electrolyte in the reaction chamber 1101 from flowing back to the liquid replenishing chamber 1102 or even flowing into the washing chamber 1103 and affecting the washing effect of the water in the washing chamber 1103, the liquid level sensor detects that the maximum height in the reaction chamber 1101 is lower than the lowest height h2 of the first liquid outlet 1108, and therefore makes the height H of the anode plate 123 also lower than h2.

[0096] Based on the foregoing description, those skilled in the art will understand that the gas conditioning device 100 in some embodiments of the present invention not only avoids the operation of separately replenishing the gas washing chamber 1103, but also because the container 110 simultaneously defines the reaction chamber 1101, the liquid replenishing chamber 1102 and the gas washing chamber 1103, the overall structure of the gas conditioning device 100 is more compact, thereby reducing the spatial size of the gas conditioning device 100.

[0097] like Fig. 9 As shown, in some other embodiments of the present invention, the present invention further provides a fresh-keeping device 200, which includes a box body 210 and the atmosphere-conditioning device 100 described in any of the above embodiments.

[0098] Continue reading Fig. 9 In some other embodiments of the present invention, the box 210 defines a low oxygen space 211 , and the gas conditioning device 100 is configured to consume oxygen in the low oxygen space 211 .

[0099] Furthermore, the box 210 may also define a high oxygen space 212 , and the gas conditioning device 100 is further configured to supply oxygen to the high oxygen space 212 , so that the gas conditioning device 100 increases the oxygen concentration in the high oxygen space 212 while reducing the oxygen concentration in the low oxygen space 211 .

[0100] In the present invention, the fresh-keeping device 200 may be a fresh-keeping device 200 with refrigeration and / or freezing functions, such as a refrigerator, a freezer, a freezer, etc.

[0101] Those skilled in the art can understand that when the fresh-keeping device 200 of the present invention uses the atmosphere-conditioning device 100 described in any of the foregoing embodiments, it can prevent the electrolyte from entering the interior of the fresh-keeping device 200 along with the oxygen, thereby contaminating the food and corroding the refrigerator.

[0102] So far, the technical solution of the present invention has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the present invention is not limited to these specific embodiments. Without departing from the technical principles of the present invention, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principles of the present invention will fall within the protection scope of the present invention.
