Description

Technical Field

[0001] This invention relates to preservation technology, and in particular to refrigerators. Background Technology

[0002] Modified atmosphere storage (MAP) achieves its preservation purpose by adjusting the gas ratio in the storage space. To achieve MAP, refrigerators typically need to be equipped with a gas processing device, which treats specific gas components to increase or decrease their concentration.

[0003] The inventors recognized that when specific gas components in multiple spaces need to be processed, setting up a separate gas processing device for each space would result in a large and complex system, high manufacturing costs, and a significant reduction in the refrigerator's volume ratio.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Summary of the Invention

[0005] One object of the present invention is to overcome at least one technical defect in the prior art and to provide a refrigerator.

[0006] A further objective of this invention is to enable the gas handling device to serve multiple purposes, simplify the refrigerator structure, and improve preservation performance.

[0007] Another further objective of this invention is to flexibly increase or decrease the oxygen content of the storage space to meet the storage needs of users at different times, improve space utilization, and optimize the user experience.

[0008] Another further objective of the present invention is to adjust the oxygenation rate of the storage space.

[0009] Another further objective of the present invention is to reduce the gas passage structure and optimize the spatial layout of the refrigerator.

[0010] In particular, the present invention provides a gas processing device, comprising: a housing having a plurality of storage spaces inside; and a gas processing device having a plurality of electrode plates with different orientations, such that each electrode plate is respectively provided with a storage space in gas flow communication with it, configured to process a specific gas component of the storage space through an electrochemical reaction.

[0011] Optionally, each electrode plate segment is provided with a corresponding counter electrode plate segment to form multiple sets of electrode pairs.

[0012] Optionally, the electrode plate segment is a cathode and is configured to consume oxygen in the storage space through an electrochemical reaction under the action of the electrolysis voltage; and the electrode plate segment is an anode and is configured to provide reactants to the corresponding electrode plate segment and generate oxygen through an electrochemical reaction under the action of the electrolysis voltage.

[0013] Optionally, the refrigerator also includes: a power supply circuit configured to provide the electrolytic voltage required for the electrochemical reaction to multiple sets of electrode pairs, and the power supply circuit is provided with multiple switching components, which are connected one-to-one with each set of electrode pairs and configured to be opened and closed in a controlled manner to adjust the on / off state between the corresponding electrode pair and the power supply circuit.

[0014] Optionally, the storage space includes an external environmental space and a first preservation space disposed within the external environmental space; and the multiple electrode plate segments include: a first preservation plate segment, which is in airflow communication with the first preservation space; and at least one regulating plate segment, which is in airflow communication with the external environmental space.

[0015] Optionally, the storage space also includes a second preservation space located within the surrounding environment; and the multiple electrode plate segments also include a second preservation plate segment, which is in airflow communication with the second preservation space.

[0016] Optionally, the regulating plate segment and its counter electrode segment are configured to controllably switch on the electrolysis voltage when the oxygen content is increased in the first preservation space and / or the second preservation space.

[0017] Optionally, there may be two or more adjustment plates.

[0018] Optionally, multiple electrode plate segments and multiple counter electrode plate segments respectively form a hollow quadrangular prism; and the hollow quadrangular prism containing the electrode plate segments is fitted outside the hollow quadrangular prism containing the counter electrode plate segments.

[0019] Optionally, the first preservation space and the second preservation space are arranged side by side in the horizontal direction; and the hollow quadrangular prism where the electrode plate segment is located is disposed between the first preservation space and the second preservation space, and the first preservation plate segment and the second preservation plate segment are distributed on both sides of the horizontal direction of the hollow quadrangular prism so as to communicate with the airflow of the first preservation space and the second preservation space respectively.

[0020] The refrigerator of the present invention has multiple storage spaces inside the cabinet, and the electrode plates of the gas processing device are oriented in different directions. This facilitates the airflow of each electrode plate to the corresponding storage space, thereby processing the specific gas components of the storage space through electrochemical reaction. Therefore, only one gas processing device is needed to adjust the atmosphere of multiple storage spaces at the same time. The refrigerator of the present invention can realize the multi-purpose function of the gas processing device, which helps to simplify the refrigerator structure and improve the preservation performance.

[0021] Furthermore, in the refrigerator of the present invention, since the first and second preservation spaces can respectively reduce the oxygen content using their respective corresponding preservation plates, and can also increase the oxygen content using the electrochemical reaction of the regulating plate and its electrode plate, the refrigerator can flexibly increase or decrease the oxygen content of the storage space based on the solution of the present invention. This is beneficial to realize the functional reuse of the storage space, so as to meet the storage needs of users at different times, improve space utilization, and optimize the user experience.

[0022] Furthermore, in the refrigerator of the present invention, since there are two or more adjustment plates, different oxygen generation rates can be obtained by selecting different numbers of adjustment plates to initiate the electrochemical reaction. Therefore, based on the solution of the present invention, the refrigerator can adjust the oxygenation rate of the storage space and further improve the preservation performance.

[0023] Furthermore, in the refrigerator of the present invention, since multiple electrode plates and multiple counter electrode plates respectively form a hollow quadrangular prism, and the hollow quadrangular prism containing the electrode plates is fitted outside the hollow quadrangular prism containing the counter electrode plates, the electrode plates are opposite each other in pairs. When the gas handling device is placed between the storage spaces arranged side by side, each storage space can be opposite to one electrode plate. The unique structure of the gas handling device can be perfectly matched with the layout structure of the refrigerator storage space. The ingenious structure helps to reduce the gas path structure and optimize the spatial layout of the refrigerator.

[0024] The above and other objects, advantages and features of the present invention will become more apparent to those skilled in the art from the following detailed description of specific embodiments of the invention in conjunction with the accompanying drawings. Attached Figure Description

[0025] The following sections will describe some specific embodiments of the invention in a detailed manner by way of example and not limitation, with reference to the accompanying drawings. The same reference numerals in the drawings denote the same or similar parts or portions. Those skilled in the art should understand that these drawings are not necessarily drawn to scale. In the drawings:

[0030] Figure 5 This is a schematic diagram of the power supply circuit of the gas handling device of a refrigerator according to some embodiments of the present invention. Detailed Implementation

[0031] Figure 1 This is a schematic structural diagram of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 of this embodiment should be interpreted broadly, for example, it can be a refrigerator 10, a freezer, a storage cabinet, or other storage equipment with low-temperature preservation function.

[0032] Refrigerator 10 generally includes a cabinet 100 and a gas handling device 200. The cabinet 100 has multiple storage spaces inside. The storage spaces in this embodiment should be interpreted broadly as spaces that are separated from each other. "Separated" can mean completely separated or partially separated. For example, a storage space can refer to the interior space of a storage compartment, the interior space of a storage container located within a storage compartment, or the surrounding environmental space 123 formed within a storage compartment and located outside the storage container.

[0033] Figure 2 This is a schematic structural diagram of a gas handling device 200 for a refrigerator 10 according to an embodiment of the present invention. Figure 3 yes Figure 2 Another schematic structural diagram of the gas handling device 200 of the refrigerator 10 shown, in which some electrode pairs are omitted.

[0034] The gas processing device 200 has multiple electrode plate segments 242 with different orientations, such that each electrode plate segment 242 is respectively provided with a storage space in airflow communication with it, and is configured to process specific gas components in the storage space through an electrochemical reaction. In other words, the gas processing device 200 has multiple electrode plate segments 242 with different orientations to allow airflow communication with storage spaces in different locations, thereby adjusting the specific gas components in the storage space. In this embodiment, the gas processing device 200 processes specific gas components in the gas through an electrochemical reaction of the electrodes, creating a specific preservation environment in the storage space.

[0035] The different orientations of the multiple electrode plate segments 242 mean that the multiple electrode plate segments 242 are not located in the same plane. For example, adjacent electrode plate segments 242 can be at a certain angle or arc, which makes it possible for multiple electrode plate segments 242 to face different storage spaces at the same time and to communicate with different storage spaces through airflow at the same time.

[0036] Since the cabinet 100 has multiple storage spaces, the electrode plates 242 of the gas treatment device 200 are configured to face different directions. This facilitates the connection between each electrode plate 242 and the airflow of the corresponding storage space, thereby treating the specific gas components of the storage space through electrochemical reaction. Therefore, only one gas treatment device 200 is needed to simultaneously adjust the atmosphere of multiple storage spaces. The refrigerator 10 of this embodiment can realize the multi-purpose function of the gas treatment device 200, which helps to simplify the structure of the refrigerator 10 and improve the preservation performance.

[0037] In some optional embodiments, each electrode plate segment 242 is respectively provided with a corresponding counter electrode plate segment 222 to form multiple sets of electrode pairs. That is, each electrode plate segment 242 has a corresponding counter electrode plate segment.

[0038] In some optional embodiments, the polarity of multiple electrode plate segments 242 can be the same, and the polarity of multiple counter electrode plate segments 222 can be the same. This helps to ensure the consistency of electrode plate segments 242 and counter electrode plate segments 222, and reduces or avoids misalignment.

[0039] In each electrode pair, the polarity of electrode plate segment 242 is opposite to that of counter electrode plate segment 222, and they can be either the anode or the cathode.

[0040] Since each electrode plate segment 242 has a corresponding counter electrode segment to form multiple sets of electrode pairs, the two electrodes of each set of electrode pairs can carry out different electrochemical reactions and obtain different atmosphere control effects. Therefore, the scheme based on this embodiment is beneficial to improving the flexibility of the atmosphere control process of the gas treatment device 200.

[0041] By setting multiple counter electrode plate segments 222 and aligning them one-to-one with multiple electrode plate segments 242, multiple sets of electrode pairs are formed. Each set of electrode pairs can independently carry out electrochemical reactions, thereby independently regulating the gas composition of the corresponding storage space. This allows the gas processing device 200 to adapt to the different atmosphere control requirements of multiple storage spaces, which is beneficial to improving the versatility of the gas processing device 200.

[0042] Of course, in some alternative embodiments, the polarities of multiple electrode plate segments 242 may not be exactly the same, and the polarities of multiple counter electrode plate segments 222 may not be exactly the same, as long as the polarities of the electrode plate segments 242 and the counter electrode plate segments 222 of each electrode pair are opposite. In this case, the polarity of the electrode plate segments 242 connected to the airflow can be set according to the actual air conditioning requirements of the storage space.

[0043] The structure of the refrigerator 10 will be further described below using the case where multiple electrode segments 242 have the same polarity and multiple counter electrode segments 222 have the same polarity as an example. In some optional embodiments, the electrode segments 242 are cathodes and are configured to consume oxygen in the storage space through an electrochemical reaction under the action of an electrolytic voltage. The counter electrode segments 222 are anodes and are configured to provide reactants to the corresponding electrode segments 242 and generate oxygen through an electrochemical reaction under the action of an electrolytic voltage.

[0044] The cathode is connected to the negative terminal of the power supply and undergoes the reduction reaction. The anode is connected to the positive terminal of the power supply and undergoes the oxidation reaction.

[0045] The gap between electrode plate segment 242 and counter electrode plate segment 222 forms an electrolytic chamber 230 for holding electrolyte. The electrolytic chamber 230 can hold an alkaline electrolyte, such as 0.1-8 mol / L NaOH or KOH, the concentration of which can be adjusted according to actual needs.

[0046] The specific gaseous component in this embodiment refers to oxygen. For example, oxygen in the air can undergo a reduction reaction at the cathode, namely: O2 + 2H2O + 4e - →4OH - OH produced at the cathode - An oxidation reaction can occur at the anode to produce oxygen, i.e., 4OH⁻. - →O2 + 2H2O + 4e - The anode utilizes OH... - During the electrochemical reaction, reactants, such as electrons (e), are also provided to the cathode. - .

[0047] Of course, the examples of electrochemical reactions and their equations above are merely illustrative. Based on understanding these embodiments, those skilled in the art should be able to readily extend the refrigerator 10 of this embodiment to other types of electrochemical reactions and to treat other types of specific gas components, such as electrochemical reactions for generating or consuming carbon dioxide, electrochemical reactions for generating or consuming nitrogen, electrochemical reactions for generating or consuming ethylene, etc., and these extensions should all fall within the protection scope of this invention.

[0048] With the above structure, the gas processing device 200 can process the oxygen in the storage space of the refrigerator 10 to conform to the development concept of low-oxygen preservation, extend the shelf life of fruits, vegetables and other food, and improve the preservation performance of the refrigerator 10.

[0049] Meanwhile, since oxygen is generated during the electrochemical reaction at the anode, this oxygen can be utilized, for example, by being transported to the high-oxygen space of the refrigerator 10. This can improve the controlled atmosphere capability of the refrigerator 10, enabling it to create both low-oxygen and high-oxygen preservation atmospheres at the same time.

[0050] Figure 4 This is a schematic diagram of the internal structure of a refrigerator 10 according to some embodiments of the present invention.

[0051] In some alternative embodiments, the storage space includes an external environmental space 123 and a first preservation space 121 disposed within the external environmental space 123. The first preservation space 121 is an independent space disposed within the external environmental space 123.

[0052] The plurality of electrode segments 242 include a first preservation plate segment 242a and at least one regulating plate segment. The first preservation plate segment 242a is in airflow communication with the first preservation space 121. When the first preservation plate segment 242a undergoes an electrochemical reaction, it can utilize oxygen within the first preservation space 121 as a reactant, thereby achieving oxygen reduction. At least one regulating plate segment is in airflow communication with the external environmental space 123. When the regulating plate segment undergoes an electrochemical reaction, it can utilize oxygen within the external environmental space 123 as a reactant, and the corresponding counter electrode segment 222 can generate oxygen through an electrochemical reaction.

[0053] When it is necessary to reduce the oxygen content of the first preservation space 121, the electrolytic voltage of the electrode pair belonging to the first preservation plate segment 242a can be turned on. When it is necessary to increase the oxygen content of the first preservation space 121, the electrolytic voltage of at least one electrode pair belonging to an adjustment plate segment can be turned on, and the oxygen generated by the corresponding counter electrode segment 222 of the adjustment plate segment can be guided to the first preservation space 121.

[0054] For example, the gas processing device 200 has an electrolysis chamber and an exhaust port. The electrolysis chamber is used to hold an electrolyte. Multiple electrode pairs can share the electrolyte. The electrolyte can be alkaline, such as NaOH or KOH, and its concentration can be set according to actual needs. The exhaust port is connected to the electrolysis chamber and is used to discharge the oxygen generated by the counter electrode plate segment 222. The refrigerator 10 may further include a gas guide pipe that connects the storage space and the electrolysis chamber, for guiding the oxygen discharged from the exhaust port to the storage space. Here, the storage space refers to the space where the oxygen content needs to be increased to create a high-oxygen atmosphere.

[0055] In some optional embodiments, the storage space further includes a second preservation space 122 located within the peripheral environment space 123. The second preservation space 122 is an independent space disposed within the peripheral environment space 123. The plurality of electrode plate segments 242 also include a second preservation plate segment 242b, which is in airflow communication with the second preservation space 122. When the second preservation plate segment 242b undergoes an electrochemical reaction, it can utilize the oxygen in the second preservation space 122 as a reactant, thereby achieving the purpose of reducing oxygen.

[0056] When it is necessary to reduce the oxygen content of the second preservation space 122, the electrolytic voltage of the electrode pair belonging to the second preservation plate segment 242b can be turned on. When it is necessary to increase the oxygen content of the second preservation space 122, the electrolytic voltage of at least one electrode pair belonging to an adjustment plate segment can be turned on, and the oxygen generated by the corresponding counter electrode segment 222 of the adjustment plate segment can be guided to the second preservation space 122.

[0057] In other words, the regulating plate segment and its counter electrode segment 222 are configured to controllably switch on the electrolysis voltage when the oxygen content of the first preservation space 121 and / or the second preservation space 122 is increased. That is, when any one or more of the first preservation space 121 and the second preservation space 122 needs to increase the oxygen content, the electrolysis voltage of at least one regulating plate segment can be switched on to provide oxygen to the first preservation space 121 and / or the second preservation space 122.

[0058] Since the first preservation space 121 and the second preservation space 122 can reduce the oxygen content by utilizing their respective corresponding preservation plates, and can also increase the oxygen content by utilizing the electrochemical reaction of the regulating plate and its counter electrode plate 222, the refrigerator 10 can flexibly increase or decrease the oxygen content of the storage space based on the solution of this embodiment. This is beneficial to realize the functional reuse of the storage space, so as to meet the storage needs of users at different times, improve space utilization, and optimize the user experience.

[0059] In some further embodiments, there are two or more regulating plates, for example, two, three, or four. Since there are two or more regulating plates, different oxygen generation rates can be obtained by selecting different numbers of regulating plates to initiate the electrochemical reaction. Therefore, based on the solution of this embodiment, the refrigerator 10 can adjust the oxygenation rate of the storage space, further improving the preservation performance.

[0060] In some optional embodiments, multiple electrode plate segments 242 and multiple counter electrode plate segments 222 respectively form a hollow quadrangular prism. The hollow quadrangular prism containing the electrode plate segments 242 is fitted over the hollow quadrangular prism containing the counter electrode plate segments 222.

[0061] Since multiple electrode segments 242 and multiple counter electrode segments 222 respectively form a hollow quadrangular prism, and the hollow quadrangular prism containing the electrode segments 242 is fitted outside the hollow quadrangular prism containing the counter electrode segments 222, the electrode segments 242 are opposite each other in pairs. When the gas handling device 200 is placed between two storage spaces arranged side by side, each storage space can be opposite to one electrode segment 242. The unique structure of the gas handling device 200 can be perfectly matched with the layout structure of the storage space of the refrigerator 10. The ingenious structure helps to reduce the gas path structure and optimize the spatial layout of the refrigerator 10.

[0062] For example, in some optional embodiments, the first preservation space 121 and the second preservation space 122 are arranged side by side in the transverse direction. The hollow quadrangular prism containing the counter electrode plate segment 222 is disposed between the first preservation space 121 and the second preservation space 122, and the first preservation plate segment 242a and the second preservation plate segment 242b are distributed on both sides of the hollow quadrangular prism so as to communicate with the airflow of the first preservation space 121 and the second preservation space 122 respectively.

[0063] Of course, the spatial layout of the refrigerator 10 is not limited to this. For example, in some alternative embodiments, the first preservation space 121 and the second preservation space 122 are arranged side by side vertically. The hollow quadrangular prism containing the counter electrode plate segment 222 is disposed between the first preservation space 121 and the second preservation space 122, and the first preservation plate segment 242a and the second preservation plate segment 242b are distributed on the upper and lower sides of the hollow quadrangular prism so as to communicate with the airflow of the first preservation space 121 and the second preservation space 122 respectively.

[0064] The gap between electrode plate segment 242 and counter electrode plate segment 222 forms an electrolytic chamber for holding electrolyte. In some optional embodiments, the gas treatment device 200 further includes a first protective frame and a second protective frame. The first protective frame is a hollow quadrangular prism and is fitted over the hollow prism containing electrode plate segment 242. The second protective frame is also a hollow prism and is fitted inside or outside the hollow prism containing counter electrode plate segment 222. The first and second protective frames seal the gap between electrode plate segment 242 and counter electrode plate segment 222.

[0065] The electrode plate segment 242 and the counter electrode segment 222 are protected by a first protective frame and a second protective frame, respectively. This can improve the structural strength of the gas treatment device 200 to a certain extent and reduce or avoid electrolyte leakage. In some further embodiments, the first protective frame may be provided with vent holes to allow gas to pass through, thereby avoiding complete obstruction of the electrode plate segment 242 and ensuring the normal operation of the modified atmosphere process.

[0066] In some optional embodiments, the first preservation space 121 and the second preservation space 122 can each be a storage drawer, with a ventilation area on the drawer wall to allow airflow communication with the corresponding electrode plate segment 242. For example, the electrode plate segment 242 can cover the side of the ventilation area facing away from the drawer interior space, thereby shielding the ventilation area. The ventilation area can be formed by drilling holes or openings.

[0067] It should be noted that although multiple electrode plate segments 242 and multiple counter electrode plate segments 222 respectively form a hollow quadrangular prism, it does not mean that electrode plate segments 242 are arranged in every face of the hollow quadrangular prism where electrode plate segments 242 are located, nor does it mean that counter electrode plate segments 222 are arranged in every face of the hollow quadrangular prism where counter electrode plate segments 222 are located.

[0068] like Figure 4 As shown, the number and position of the electrode plate segments 242 and the counter electrode segments 222 can be adjusted according to actual needs. Figure 4 (a) illustrates the assembly of a gas processing device 200 with four electrode pairs with a storage space. The electrode plate segment 242 of the gas processing device 200 includes a first preservation plate segment 242a, a second preservation plate segment 242b, and two adjustment plate segments. Figure 4 (a) In comparison, Figure 4 (b) An adjustment plate segment and its counter electrode segment 222 are omitted. Figure 4 (c) All adjustment plate segments and their counter electrode segments 222 are omitted. Figure 4 (d) The first preservation plate segment 242a and the second preservation plate segment 242b are omitted.

[0069] Figure 5 This is a schematic diagram of the power supply circuit 300 of the gas handling device 200 of the refrigerator 10 according to some embodiments of the present invention. The diagram shows three different power supply structures of the gas handling device 200 having four sets of electrode pairs.

[0070] In some optional embodiments, the refrigerator 10 further includes a power supply circuit 300 configured to provide the electrolytic voltage required for the electrochemical reaction to multiple sets of electrode pairs, and the power supply circuit 300 is provided with multiple switching components, which are connected to each set of electrode pairs in a one-to-one correspondence, and are respectively configured to be opened and closed in a controlled manner to adjust the on / off state between the corresponding electrode pairs and the power supply circuit 300.

[0071] In other words, the on / off state between each electrode pair and the power supply circuit 300 is controlled by a corresponding switching component. Since the on / off state between the electrode pair and the power supply circuit 300 directly determines whether the electrolytic voltage is applied to that electrode pair, controlling the opening and closing state of the switching components allows for control over whether the electrochemical reaction is initiated for the corresponding electrode pair. Based on this, the refrigerator 10 can select one or more electrode pairs to initiate the electrochemical reaction according to actual needs, offering high flexibility.

[0072] like Figure 5As shown in (a), when the first preservation space 121 and the second preservation space 122 need to reduce the oxygen content, the electrode pair containing the first preservation plate segment 242a and the electrode pair containing the second preservation plate segment 242b are controlled to work, switches K1, K4, K3, and K9 are turned on, and other switches are turned off; when the first preservation space 121 needs to reduce the oxygen content and the second preservation space 122 needs to increase the oxygen content, the electrode pair containing the first preservation plate segment 242a is controlled to work, switches K3 and K9 are turned on, and other switches are turned off, and the oxygen generated by the electrode plate segment 222 of the first preservation plate segment 242a is delivered to the second preservation space 122. This is equivalent to oxygen being replaced from the first preservation space 121 to the second preservation space 122. When the first preservation space 121 needs to reduce its oxygen content and the second preservation space 122 needs to increase its oxygen content at a relatively fast rate, the electrode pairs of the first preservation plate segment 242a and the first adjustment plate segment 242c are activated, switches K3 and K8 are turned on, and other switches are turned off, allowing oxygen to be replaced from the first preservation space 121 and the surrounding environment space 123 to the second preservation space 122. When the second preservation space 122 needs to reduce its oxygen content and the first preservation space 121 needs to increase its oxygen content, the electrode pair of the second preservation plate segment 242b is activated. When K1 and K4 are turned on and other switches are turned off, oxygen is displaced from the second preservation space 122 to the first preservation space 121. When the second preservation space 122 needs to reduce the oxygen content and the first preservation space 121 needs to increase the oxygen content at a faster rate, the electrode pairs of the second preservation plate segment 242b and the first adjustment plate segment 242c are activated, K1, K5, and K7 are turned on, other switches are turned off, and oxygen is displaced from the second preservation space 122 and the surrounding environment space 123 to the first preservation space 121. When the second preservation space 122 needs to reduce the oxygen content and the first preservation space 121 needs to increase the oxygen content at a faster rate, the electrode pairs of the second preservation plate segment 242b and the first adjustment plate segment 242c are activated, K1, K5, and K7 are turned on, other switches are turned off, and oxygen is displaced from the second preservation space 122 and the surrounding environment space 123 to the first preservation space 121. When the oxygen content is at a certain level, the electrode pairs containing the second preservation plate section 242b, the first regulating plate section 242c, and the second regulating plate section 242d are activated, K2 and K7 are turned on, and other switches are turned off. Oxygen is displaced from the second preservation space 122 and the surrounding environment space 123 to the first preservation space 121. When the first preservation space 121 and the second preservation space 122 need to increase the oxygen content, the electrode pairs containing the first regulating plate section 242c and / or the second regulating plate section 242d are activated. For example, switches K10, K2, K5, and K4 are turned on, and other switches are turned off, or switches K11, K3, and K8 are turned on, and other switches are turned off.

[0073] like Figure 5As shown in (b), when the first preservation space 121 and the second preservation space 122 need to reduce the oxygen content, the electrode pair containing the first preservation plate segment 242a and the electrode pair containing the second preservation plate segment 242b are activated, switches K2 and K4 are turned on, and other switches are turned off. When the first preservation space 121 needs to reduce the oxygen content and the second preservation space 122 needs to increase the oxygen content, the electrode pair containing the first preservation plate segment 242a is activated, switch K4 is turned on, and other switches are turned off, and oxygen is replaced from the first preservation space 121 to the second preservation space. 122; When the first preservation space 121 needs to reduce the oxygen content and the second preservation space 122 needs to adjust its settings to increase the oxygen content at a faster rate, the electrode pairs of the first preservation plate segment 242a and at least one adjustment plate segment are activated, switches K4 and K1 are turned on, and other switches are turned off; When the first preservation space 121 and the second preservation space 122 need to increase the oxygen content respectively, the electrode pairs of the first adjustment plate segment 242c and / or the second adjustment plate segment 242d can be controlled to operate, for example, switches K2 and K4 can be selectively turned on, and other switches are turned off.

[0074] like Figure 5 (c) As shown, when the first preservation space 121 and the second preservation space 122 need to reduce the oxygen content, the electrode pair containing the first preservation plate segment 242a and the electrode pair containing the second preservation plate segment 242b are controlled to work, switches K1 and K3 are turned on, and other switches are turned off; when the first preservation space 121 needs to reduce the oxygen content and the second preservation space 122 needs to increase the oxygen content, the electrode pair containing the first preservation plate segment 242a is controlled to work, switch K3 is turned on, other switches are turned off, and oxygen is replaced from the first preservation space 121 to the second preservation space 122. 22; When the first preservation space 121 needs to reduce the oxygen content and the second preservation space 122 needs to adjust to increase the oxygen content at a faster rate, the electrode pair containing the first preservation plate segment 242a and at least one adjustment plate segment will operate, and switches K3, K2 or K4 will be turned on, while other switches will be turned off; When the first preservation space 121 and the second preservation space 122 need to increase the oxygen content respectively, the electrode pair containing the first adjustment plate segment 242c and / or the second adjustment plate segment 242d can be controlled to operate, for example, switches K2 and K4 can be selectively turned on, while other switches are turned off.

[0075] In some embodiments, the gas processing device 200 further includes a first protective frame 212 and a second protective frame 214. The first protective frame 212 is a hollow prism and is fitted over the hollow prism containing the electrode plate segment 242. The second protective frame 214 is also a hollow prism and is fitted over the hollow prism containing the counter electrode plate segment 222.

[0076] The electrode plate segment 242 and the counter electrode segment 222 are protected by a first protective frame 212 and a second protective frame 214, respectively. This can improve the structural strength of the gas treatment device 200 to a certain extent and reduce or avoid electrolyte leakage. In some further embodiments, the first protective frame 212 may be provided with vent holes to allow gas to pass through, thereby avoiding complete obstruction of the electrode plate segment 242 and ensuring the normal operation of the modified atmosphere process.

[0077] It should be noted that the first protective frame 212 and the second protective frame 214 also serve an integration function, respectively assembling the separately set electrode plate segment 242 and counter electrode plate segment 222 into a whole.

[0078] In some alternative embodiments, the gas processing device 200 may further include a first closure 216 and a second closure 218.

[0079] Specifically, the first sealing portion 216 seals the gap between the first end of the electrode plate segment 242 and the first end of the counter electrode plate segment 222. The second sealing portion 218 seals the gap between the second end of the electrode plate segment 242 and the second end of the counter electrode plate segment 222. In other words, the first sealing portion 216 and the second sealing portion 218 respectively seal the gaps at both ends of the electrode plate segment 242 and the counter electrode plate segment 222, thereby sealing the electrolysis chamber 230.

[0080] In some optional embodiments, the first sealing portion 216 and the second sealing portion 218 may be in the shape of annular cover plates to seal the gap between the two ends of the multi-faceted electrode and the multi-faceted electrode, and may be connected to the multi-faceted electrode and the multi-faceted electrode by any means such as riveting, welding, screwing, snapping or bonding.

[0081] In the above embodiments, an airflow channel 250 is formed on the side of the counter electrode plate segment 222 facing away from the electrode plate segment 242 for airflow passage. When the counter electrode plate segment 222 is the cathode and the electrode plate segment 242 is the anode, the gas to be treated can flow along the extension direction of the airflow channel 250. During the flow, oxygen in the gas continuously participates in the electrochemical reaction and is consumed. This results in the gas exiting the airflow channel 250 containing very little oxygen, enhancing the controlled atmosphere effect, reducing the time required for controlled atmosphere treatment, and reducing the number of airflow cycles. The storage space of the refrigerator 10 may only require one or a few airflow cycles between itself and the gas treatment device 200 to meet the controlled atmosphere requirements of the storage space.

[0082] The refrigerator 10 of the present invention has multiple storage spaces inside the cabinet 100. The electrode plates 242 of the gas processing device 200 are arranged with different orientations. This facilitates that each electrode plate 242 is connected to the airflow of the corresponding storage space, thereby processing the specific gas components of the storage space through electrochemical reaction. Therefore, only one gas processing device 200 is needed to adjust the atmosphere of multiple storage spaces at the same time. The refrigerator 10 of the present invention can realize the multi-purpose function of the gas processing device 200, which helps to simplify the structure of the refrigerator 10 and improve the preservation performance.

[0083] 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.
