Some specific embodiments of the invention will be described in detail hereinafter by way of example and not by way of limitation with reference to the accompanying drawings. The same reference numbers will be used throughout the drawings to refer to the same or like parts or portions. It will be appreciated by those skilled in the art that the drawings are not necessarily drawn to scale. In the accompanying drawings:

Detailed Description
Fig. 1 is a schematic block diagram of a gas processing apparatus 200 according to one embodiment of the present invention. The gas treatment apparatus 200 of the present embodiment is used to treat a specific gas component in a gas, for example, to increase or decrease the content of the specific gas component. The gas treatment device 200 may generally include a multi-faceted electrode. The gas treatment apparatus 200 of the present embodiment treats a specific gas component in a gas by electrochemical reaction of an electrode.
The multi-faceted electrode has a plurality of differently oriented plates 222, each segment of plate 222 configured to treat a particular gas component within the space in which it is oriented by an electrochemical reaction. The different orientations of the multi-segment plates 222 means that the multi-segment plates 222 are not in the same plane. For example, adjacent plates 222 may be angled or curved, which facilitates that the multi-faceted electrodes may be facing different spaces simultaneously and may be in gas flow communication with different spaces simultaneously.
Since the gas treatment apparatus 200 has the multi-surface electrode, each of the electrode plates 222 of the multi-surface electrode can face different spaces and treat the specific gas components in the facing spaces, the specific gas components in the plurality of spaces can be treated by the same gas treatment apparatus 200 based on the scheme of the embodiment, which is advantageous in simplifying the architecture of the refrigerator 10 and reducing the manufacturing cost.
In some alternative embodiments, the gas treatment device 200 further includes a multi-faceted counter electrode having multiple segments of differently oriented counter plates 242, with one pair of plates 242 opposing one plate 222 to form multiple sets of electrode pairs. That is, each segment of the electrode plate 222 has a counter electrode plate 242 disposed corresponding thereto. In each set of electrode pairs, the pole plate 222 is of opposite polarity to the counter plate 242 and may be either of an anode and a cathode, respectively.
Because each polar plate 222 has a corresponding counter polar plate 242 to form a plurality of groups of electrode pairs, the two poles of each group of electrode pairs respectively perform different electrochemical reactions and can obtain different air conditioning effects, the solution according to the embodiment is beneficial to improving the flexibility of the air conditioning process of the gas treatment device 200.
By arranging the multi-section counter electrode plates 242 and enabling the multi-section counter electrode plates 242 to be opposite to the multi-section electrode plates 222 one by one, a plurality of groups of electrode pairs can be formed, and each group of electrode pairs can respectively and independently perform electrochemical reaction, so that the gas components in the corresponding space can be independently regulated, the gas treatment device 200 can adapt to different gas regulation requirements of a plurality of spaces, and the universality of the gas treatment device 200 can be improved.
Of course, in some alternative embodiments, the polarities of the multi-segment plates 222 of the multi-face electrode may be the same, and the polarities of the multi-segment plates 242 of the multi-face counter electrode may be the same, which is beneficial to ensuring the uniformity of the multi-face electrode and the uniformity of the multi-face counter electrode, reducing or avoiding the occurrence of confusion.
In some alternative embodiments, the multi-faceted counter electrode may be converted to a counter electrode of another shape, for example, a flat counter electrode or a columnar counter electrode, so long as the counter electrode is guaranteed to be disposed opposite each of the pole plates 222 of the multi-faceted electrode, respectively.
For example, each of the electrode plates 222 of the multi-surface electrode may be plate-shaped, and the electrode plates 222 may be folded and connected to each other so that the cross section is wavy, and in this case, a flat counter electrode may be disposed on the opposite side of the electrode plates 222. For another example, each section of polar plate 222 of the multi-surface electrode may be plate-shaped, and the multi-section polar plates 222 may be sequentially connected end to end and enclose a closed hollow prism, where the columnar counter electrode may be disposed inside the hollow prism where the multi-section polar plate 222 is located. Of course, the shapes of the multi-faceted electrode and the multi-faceted counter electrode are not limited to these examples.
In some alternative embodiments, the multi-faceted electrode and the multi-faceted counter electrode are each selected from either of an anode and a cathode. That is, the polarities of the multi-segment plates 222 of the multi-segment electrode are the same, and the polarities of the multi-segment plates 242 of the multi-segment counter electrode are the same. The polarity of the polar plate 222 is the polarity of the multi-sided electrode, and the polarity of the counter polar plate 242 is the polarity of the multi-sided counter electrode. Wherein the cathode is adapted to be connected to a negative electrode of a power source and adapted to consume oxygen by performing an electrochemical reaction. The anode is adapted to be connected to a positive electrode of a power source and adapted to provide a reactant to the cathode by performing an electrochemical reaction.
For example, the specific gas component of the present embodiment may be oxygen. Oxygen in the air may undergo a reduction reaction at the cathode, namely: o (O) 2 +2H 2 O+4e - →4OH - . OH generated by cathode - An oxidation reaction may occur at the anode and oxygen is generated, namely: 4OH - →O 2 +2H 2 O+4e - . Anode using OH - While the electrochemical reaction takes place, a reactant, e.g. an electron e, is also supplied to the cathode - 。
With the above structure, the gas treatment device 200 can treat oxygen in the storage space of the refrigerator 10, so as to conform to the development concept of low-oxygen preservation, prolong the shelf life of food materials such as fruits and vegetables, and improve the preservation performance of the refrigerator 10.
Meanwhile, as the anode generates oxygen during electrochemical reaction, the oxygen can be utilized and can be conveyed to a high-oxygen space of the refrigerator 10, for example, the air conditioning capacity of the refrigerator 10 can be improved, and a low-oxygen fresh-keeping atmosphere and a high-oxygen fresh-keeping atmosphere can be simultaneously created.
In some embodiments, the electrolytic chamber 230 may be provided with an exhaust port to allow oxygen generated at the anode to be smoothly exhausted. Oxygen generated at the anode may be exhausted through the exhaust port. For example, the exhaust port may be provided on the first or second protection frame 212 or 214 described below and located directly above the electrolytic chamber 230.
Of course, the above examples of electrochemical reactions and equations thereof are merely illustrative, and those skilled in the art should readily appreciate that the gas treatment apparatus 200 of the present embodiment can be extended to other types of electrochemical reactions and 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 such extensions are within the scope of the present invention.
Each segment 222 of the multi-faceted electrode may be a unitary piece or may be separate pieces. When each section of polar plate 222 of the multi-face electrode is an integral piece, the flat plate-shaped electrode can be formed into a plurality of sections of polar plates 222 with different orientations through a bending process, or the multi-section polar plates 222 with different orientations can be directly obtained through a forming process. When the multi-segment electrode plates 222 are discrete pieces, the multi-segment electrode plates 222 are spliced to form a multi-segment electrode, and gaps may be provided between adjacent electrode plates 222. Each segment of the multi-faceted counter electrode 242 may be a unitary piece or may be separate pieces. When each segment of counter electrode plate 242 of the multi-surface counter electrode is an integral piece, the flat plate-shaped electrode can be formed into a plurality of segments of counter electrode plates 242 with different orientations through a bending process, or the multi-segment counter electrode plates 242 with different orientations can be directly obtained through a forming process. When the multi-segment counter electrode plates 242 are discrete pieces, the multi-segment counter electrode plates 242 are spliced to form a multi-segment counter electrode, and a gap may be provided between adjacent counter electrode plates 242. Wherein "discrete components" refer to components that are each independently disposed, as opposed to the concept of "integrally formed" as referred to herein as "integral components".
The electrode plates 222 are arranged separately to form a multi-surface electrode, and the electrode plates 242 are arranged separately to form a multi-surface electrode, so that the positions and orientations of the electrode plates 222 and the electrode plates 242 can be flexibly arranged, the structure of the gas treatment device 200 is diversified and exquisite, the gas treatment device is convenient for carrying out air conditioning treatment on a plurality of storage spaces with specific space layout, a complex bending process or a forming process is not required, and the gas treatment device has the advantage of simple process.
In some alternative embodiments, the multi-segment plate 222 of the multi-face electrode and the multi-segment plate 242 of the multi-face counter electrode each enclose a hollow prism, such as a triangular prism, a quadrangular prism, a pentagonal prism, or a hexagonal prism, etc., preferably a quadrangular prism. The multi-stage plate 222 can process gases from all directions, which makes the gas treatment device 200 particularly suitable for mounting to a refrigerator 10 having a large number of storage spaces.
Because the multi-section pole plate 222 of the multi-surface electrode and the multi-section counter pole plate 242 of the multi-surface counter electrode respectively enclose a hollow prism, the volume is small, the occupied space is small, and the plurality of groups of electrode pairs can treat the gases in a plurality of different spaces at the same time and treat the gases in the same space at the same time, the air conditioning efficiency is high, so the air conditioning device 200 has the advantages of high air conditioning efficiency and small volume based on the scheme of the embodiment.
In some alternative embodiments, the hollow prism in which the multi-segment counter electrode 242 is located is sleeved outside the hollow prism in which the multi-segment counter electrode 222 is located. The side of the multi-sided electrode facing away from the multi-sided counter electrode forms a gas flow channel 250 through which gas to be treated can flow and participate as a reactant in the electrochemical reaction of the plate 222. Fig. 2 is a schematic block diagram of a gas treatment apparatus 200 according to another embodiment of the present invention, in which arrows show the direction of gas flow through a gas flow channel 250 formed in a side of a multi-faceted electrode facing away from a multi-faceted counter electrode, and in which part of the plates and counter plates are omitted.
At this time, the gas to be treated may flow along the extending direction of the gas flow channel 250, and during the flowing process, the specific gas component in the gas continuously participates in the electrochemical reaction and is consumed, so that the gas flowing out of the gas flow channel 250 contains very little specific gas component, the air conditioning effect is enhanced, the time required by the air conditioning is reduced, and the circulation times of the air flow are reduced. The air conditioning requirement of the storage space can be met by only performing one or a few times of air circulation between the storage space of the refrigerator 10 and the air treatment device 200.
The side of the multi-facing electrode facing away from the multi-faceted electrode also forms an airflow channel 250 through which the airflow passes. The multiple pairs of electrodes may treat a specific gas component in the gas flowing through or residing in the gas flow channel 250 by an electrochemical reaction.
The gap between the multi-faceted electrode and the multi-faceted counter electrode forms an electrolyte chamber 230 for containing electrolyte. The electrolytic chamber 230 can contain alkaline electrolyte, such as NaOH or KOH of 0.1-8 mol/L, and the concentration can be adjusted according to actual needs.
In some alternative embodiments, the gas treatment device 200 further comprises a first enclosure 212 and a second enclosure 214. The first protection frame 212 is in a hollow prism shape, and is sleeved outside the hollow prism body where the multi-section counter electrode plate 242 of the multi-face electrode is located. The second protection frame 214 is also in a hollow prismatic shape and is sleeved on the inner side or the outer side of the hollow prismatic body where the multi-stage polar plate 222 of the multi-stage electrode is located.
The use of the first and second shield frames 212 and 214, respectively, protects the multi-facing and multi-faceted electrodes, which may improve the structural strength of the gas treatment apparatus 200 to some extent, and reduce or avoid leakage of electrolyte. In some further embodiments, the first protective frame 212 may be provided with ventilation holes for allowing gas to pass through, so as to avoid completely shielding the multi-surface counter electrode and ensure normal operation of the air conditioning process.
It should be noted that, when the multi-stage electrode plate 222 of the multi-stage electrode and the multi-stage counter electrode plate 242 of the multi-stage counter electrode are separate pieces, the first protection frame 212 and the second protection frame 214 also perform an integrating function, so that the separately disposed electrode plate 222 and the counter electrode plate 242 are assembled into a single body.
Of course, in alternative embodiments, the hollow prism in which the multi-segment counter electrode 242 of the multi-segment counter electrode is located may be changed to a hollow prism in which the multi-segment electrode 222 of the multi-segment counter electrode is located. At this time, the multi-surface electrode can obtain a larger area of the electrode plate 222 to increase the electrochemical reaction rate, and the side of the multi-surface electrode facing away from the multi-surface counter electrode forms an air flow channel 250 for air to flow through, and the air flow channel 250 has a larger air flow space. The gas treatment device 200 is capable of achieving greater oxygen removal efficiency when the multi-faceted electrode is cathodic and is used for oxygen removal.
In some alternative embodiments, the multi-faceted electrode processes a particular gas component in a gas flowing or residing on its side facing away from the multi-faceted counter electrode through an electrochemical reaction, the multi-faceted counter electrode providing a reactant to the multi-faceted electrode through the electrochemical reaction. The airflow channel 250 surrounded by the side of the multi-surface electrode facing away from the multi-surface counter electrode is the inner space of the multi-surface electrode.
In other alternative embodiments, the polarities of the multi-faceted electrode and the multi-faceted counter electrode may be reversed, for example, the multi-faceted counter electrode may treat a particular gas component in a gas flowing or residing on its side facing away from the multi-faceted electrode by performing an electrochemical reaction, the multi-faceted electrode providing a reactant to the multi-faceted counter electrode by the electrochemical reaction. The airflow channel 250 facing the side of the multi-face electrode facing away from the multi-face electrode is the outer space of the multi-face electrode.
In some alternative embodiments, the gas treatment device 200 may further include a first enclosure 216 and a second enclosure 218.
Wherein the first closing portion 216 closes a gap between the first end of the multi-faceted electrode and the first end of the multi-faceted counter electrode. The second closing portion 218 closes a gap between the second end of the multi-faceted electrode and the second end of the multi-faceted counter electrode. That is, the first sealing portion 216 and the second sealing portion 218 seal gaps between both ends of the multi-surface electrode and the multi-surface counter electrode, respectively, so that the electrolytic chamber 230 is sealed.
In some alternative embodiments, the first sealing portion 216 and the second sealing portion 218 may have a ring cover plate shape, respectively, to seal gaps between two ends of the multi-surface electrode and the multi-surface counter electrode, and may be connected to the multi-surface electrode and the multi-surface counter electrode by riveting, welding, screwing, clamping, or bonding, respectively, in any manner.
Fig. 3 is a schematic structural view of a refrigerator 10 according to an embodiment of the present invention. The structure of the refrigerator 10 will be described below taking a case where a specific gas component is oxygen as an example.
The refrigerator 10 may generally include a cabinet 100 and the gas treatment apparatus 200 of any of the above embodiments. Wherein a storage space is formed in the case 100, for example, the storage space may include a low oxygen space and/or a high oxygen space. The cathode of the gas treatment device 200 may be in gas flow communication with the hypoxic space and reduce the oxygen content of the hypoxic space through electrochemical reactions. The anode of the gas treatment device 200 may be in gas flow communication with the high oxygen space and increase the oxygen content of the high oxygen space through an electrochemical reaction.
For example, when the cathode is a multi-surface electrode and the multi-surface electrode is sleeved in the multi-surface electrode, an air inlet pipeline and an air return pipeline can be respectively communicated between two ends of the air flow channel 250 formed on one side of the multi-surface electrode, which is opposite to the multi-surface electrode, and the low-oxygen space, so that air flow communication between the cathode and the low-oxygen space can be realized, and an air flow circulation channel can be formed. A gas flow actuating device may be connected between the gas inlet line and the low oxygen space for causing a gas flow from the low oxygen space through the gas inlet line and to the cathode and back to the low oxygen space after flowing through the gas return line.
The refrigerator 10 further has an oxygen delivery passage communicating the electrolysis chamber 230 with the high oxygen space for delivering oxygen generated at the anode to the high oxygen space. For example, the oxygen delivery passageway may have a first end connected to the exhaust port and a second end connected to the high oxygen space.
The gas treatment device 200 may be disposed within the foam of the refrigerator 10. The foam material has a certain reserved space, and the space utilization rate of the refrigerator 10 can be improved by using the reserved space to install the gas treatment device 200. The gas treatment device 200 can exert high oxygen removal efficiency and oxygen production efficiency by means of the heat-insulating environment of the foaming material.
Of course, the gas treatment device 200 may alternatively be positioned at any suitable location within the housing 100, such as within the press housing, on the duct cover, or within the storage compartment 120, etc. Fig. 3 is an example of the case of being provided in the storage compartment 120, and is not to be construed as limiting the installation position of the gas processing apparatus 200.
Because the sections of the multi-section polar plate 222 and the multi-section counter polar plate 242 respectively enclose a hollow quadrangular prism, and the hollow quadrangular prism where the counter polar plate 242 is located is sleeved outside the hollow quadrangular prism where the polar plate 222 is located, as shown in fig. 3, the counter polar plates 242 are opposite to each other, when the gas treatment device 200 is arranged between the storage spaces arranged side by side in pairs, each storage space can be opposite to one pair of polar plates 242 respectively, and the unique structure of the gas treatment device 200 can be perfectly matched with the layout structure of the storage compartment 120 of the refrigerator 10, so that the structure is ingenious, the gas path structure is reduced, and the space layout of the refrigerator 10 is optimized.
For example, in some alternative embodiments, the first storage space 121 is laterally juxtaposed with the second storage space 122. The hollow quadrangular prism in which the counter electrode plate 242 is located is disposed between the first storage space 121 and the second storage space 122, so that the counter electrode plate 242 located at two lateral sides of the hollow quadrangular prism is respectively in airflow communication with the first storage space 121 and the second storage space 122.
Of course, the spatial layout of the refrigerator 10 is not limited thereto. For example, in alternative embodiments, the first storage space 121 is longitudinally juxtaposed with the second storage space 122. The hollow quadrangular prism in which the counter electrode plate 242 is located is disposed between the first storage space 121 and the second storage space 122, so that the counter electrode plate 242 located on the upper and lower sides of the hollow quadrangular prism is respectively in airflow communication with the first storage space 121 and the second storage space 122.
Since the gas treatment device 200 and the refrigerator 10 with the same according to the present invention have the multi-surface electrode, each of the electrode plates 222 of the multi-surface electrode can be directed to a different space and treat the specific gas component in the directed space, the specific gas components in the plurality of spaces can be treated by the same gas treatment device 200 according to the present invention, which is advantageous in simplifying the architecture of the refrigerator 10 and reducing the manufacturing cost.
By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been shown and described herein in detail, many other variations or modifications of the invention consistent with the principles of the invention may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the invention. Accordingly, the scope of the present invention should be understood and deemed to cover all such other variations or modifications.
