Description

refrigerator

technical field

The invention relates to fresh-keeping technology, in particular to a refrigerator.

Background technique

Controlled atmosphere preservation, which achieves the purpose of preservation by adjusting the gas ratio of the storage space. Among the many types of gases, oxygen is one of the most concerned gas components. The oxygen treatment device can process the oxygen in the storage space to increase or decrease the oxygen content. For some food materials, when stored in a low-oxygen atmosphere, the shelf life will be extended appropriately, while for other food materials, the shelf life will be extended appropriately when stored in a high-oxygen atmosphere.

In recent years, people have paid more attention to the regulation of hypoxic atmosphere, while ignoring the regulation of high oxygen atmosphere. When it is necessary to increase the oxygen content in the storage space, the prior art lacks an effective adjustment means.

In order to achieve the purpose of modified atmosphere preservation, the refrigerator usually needs to install a gas treatment device, and use the gas treatment device to process a specific gas component, so as to increase or decrease the content of the specific gas component.

The inventors realized that when it is necessary to adjust the gas ratio of the storage space, it is usually necessary to set up a ventilation area in the storage space and install the gas treatment device on the ventilation area so that the gas treatment device communicates with the storage space. However, since the gas processing device needs to occupy a certain volume, this installation method needs to compress the volume of the storage space, thereby reducing the volume ratio of the refrigerator.

The inventors also realized that when using a gas processing device to process gas components, there are problems of poor air flow circulation and low air conditioning efficiency. Therefore, it is necessary to improve the structure of the refrigerator and optimize the air conditioning efficiency.

The inventor also realized that the oxygen processing device has a certain volume and needs to occupy a certain installation space. If the oxygen processing device is installed on the refrigerator, it will have a significant impact on the structural layout of the refrigerator. When the oxygen treatment device is installed in the storage space for storage, it will seriously reduce the volume ratio of the refrigerator.

When a gas treatment device processes a specific gas component through an electrochemical reaction, the process of the electrochemical reaction often leads to the loss of the composition of the electrolyte, which reduces the total amount of the electrolyte and changes its concentration, which will affect the normal operation of the gas treatment device. run.

The inventors have also realized that when the electrolyte of the gas treatment device is lost, not only water but also electrolyte will be lost. If only water is supplied to the gas treatment device, the loss of electrolyte cannot be compensated, and the "quality" of the electrolyte cannot be compared. Good recovery.

Further, in the refrigerator of the present invention, since the oxygen collecting part can allow the oxygen from the first storage space to enter the gas collection chamber, and allow the oxygen in the gas collection chamber to flow to the second storage space, the oxygen is equivalent to being transferred from the first storage space to the second storage space. The second storage space, therefore, the oxygen collecting part can enable the refrigerator to adjust the oxygen content of multiple different storage spaces through the transfer of oxygen, and skillfully balance the oxygen supply and demand relationship of multiple storage spaces.

Furthermore, in the refrigerator of the present invention, since the oxygen collecting part can collect the oxygen separated by the gas processing device when the gas processing device performs deoxygenation work, the oxygen, as a by-product of the gas processing device, can be sent to a specific storage space by the oxygen collecting part provided and reused, therefore, based on the solution of the present invention, the refrigerator can meet the different oxygen requirements of multiple different storage spaces with less energy consumption.

According to the refrigerator of the second aspect of the present invention, since the gas processing device is formed with a processing part and a processing air channel, the processing air channel can make the gas from the storage space flow through the processing part, so that the processing part can process a specific gas component in the gas , so when it is necessary to adjust the gas environment of the storage space, it is only necessary to connect the storage space with the processing channel, and it is not necessary to arrange the entire gas treatment device at the gas-permeable area of the storage space, and the gas treatment device can be installed in other places far away from the storage space Location. According to the solution of the present invention, by improving the airflow communication mode between the storage space and the gas processing device, the modified atmosphere preservation can be realized without affecting the volume ratio of the refrigerator.

Further, in the refrigerator of the present invention, since the processing air channel can allow the gas from the storage space to flow through the processing part, the processing air channel can fully contact the gas with the processing part during the process of guiding the gas. As a result, the refrigerator can obtain higher air-conditioning efficiency.

Further, in the refrigerator of the present invention, the processing part and the matching part are used to form hollow cylindrical electrodes nested in each other, and the gas can be processed based on the electrochemical reaction of the electrodes. Since the processing part and the matching part have a larger electrode area, it can be used with limited The volume improves the electrochemical reaction rate of the gas processing device, so that the gas processing device has the advantages of high gas conditioning efficiency and small volume.

Furthermore, the refrigerator of the present invention can improve the air conditioning capability of the refrigerator by connecting the anode electrode of the gas treatment device with the hyperoxic space through the oxygen delivery channel, and transport the oxygen generated by the anode electrode to the hyperoxic space, so that it can simultaneously create Low-oxygen fresh-keeping atmosphere and high-oxygen fresh-keeping atmosphere.

According to the refrigerator of the fourth aspect of the present invention, since a storage space for storage and an installation space outside the storage space are formed in the box, the installation space can be the inherent space provided by the refrigerator for installing other components, and the oxygen treatment device Installed in the installation space outside the storage space, the oxygen treatment device will not occupy any position in the storage space, and the storage space does not need to make room for space, so the refrigerator can achieve controlled atmosphere preservation without affecting the volume ratio.

Further, in the refrigerator of the present invention, since the storage space used for storage is a low-temperature area in the box, and the installation space is a high-temperature area in the box, its temperature is higher than that of the storage space, and the high-temperature environment can improve the electrochemical performance of the oxygen treatment device. Therefore, the oxygen treatment device of the refrigerator can maintain a high air conditioning efficiency, and at the same time solve the problem of the freezing risk of the electrolyte, which serves multiple purposes.

Detailed ways

FIG. 1 is a schematic structural view of a refrigerator 10A according to one embodiment of the present invention. The refrigerator 10A of this embodiment should be understood in a broad sense, for example, it can be a refrigerator, a freezer, a storage cabinet and other storage equipment with a low-temperature preservation function.

The refrigerator 10A may generally include a cabinet 100A and an oxygen collection part 800A. Wherein, the oxygen collecting component 800A is arranged in the box body 100A, and a gas collecting cavity 810A is formed inside it, and is configured to collect oxygen in the box body 100A. That is, the oxygen collection part 800A may allow oxygen to flow into the gas collection chamber 810A, and the gas collection chamber 810A filled with oxygen may serve as an oxygen supply chamber.

Since the oxygen collection part 800A is arranged in the box body 100A, the gas collection chamber 810A is formed inside the oxygen collection part 800A. By using the gas collection chamber 810A to collect the oxygen in the box body 100A, when it is necessary to increase the oxygen content of a certain storage space At this time, the gas collection chamber 810A can be used as an oxygen supply chamber to supply oxygen to the storage space, so the refrigerator 10A can quickly increase the oxygen content in the storage space without the need for temporary oxygen production, saving time and high efficiency, and solving the problem of high and low oxygen coexistence technology in the refrigerator field. However, there are problems such as high energy consumption and complicated control that need to be individually adjusted for air conditioning.

It needs to be emphasized that, for controlled atmosphere preservation, in order to achieve a high-oxygen atmosphere, those skilled in the art can easily think of temporary oxygen generation or on-demand oxygen generation. However, the inventors have realized that temporary oxygen generation or on-demand oxygen generation requires a certain amount of oxygen generation time and will generate energy consumption. Moreover, limited by factors such as the high volume ratio of the refrigerator 10A, even if oxygen needs to be delivered to a certain space, those skilled in the art would not think of storing oxygen on the refrigerator 10A. Therefore, the inventors of the present application creatively set the oxygen collection part 800A on the refrigerator 10A, and use the oxygen collected by the oxygen collection part 800A to adjust the oxygen content in the storage space, which breaks through the shackles of the prior art, and provides a new way for the refrigerator 10A It provides a new idea to realize the air-conditioning preservation of various atmospheres, and at the same time solves multiple technical problems such as high energy consumption in the air-conditioning process of the refrigerator 10A, which serves multiple purposes.

In some optional embodiments, a storage space is formed inside the box body 100A. The storage space in this embodiment should be understood broadly. For example, the storage space may refer to an inner space of a storage compartment, or an inner space of a storage container disposed in the storage compartment, or a peripheral environmental space formed in the storage compartment and located outside the storage container.

For example, a first storage space 110A and a second storage space 120A may be formed in the box body 100A. Certainly, in some embodiments, other storage spaces may also be formed in the box body 100A. The first storage space 110A in this embodiment may refer to a hypoxic space, and the second storage space 120A may refer to a high oxygen space.

The air collection chamber 810A has an air inlet 811A and an air outlet 812A, wherein the air inlet 811A is configured to allow oxygen from the first storage space 110A to enter the air collection chamber 810A, and the air outlet 812A is configured to allow oxygen in the air collection chamber 810A to Flow to the second storage space 120A. That is, the gas collection chamber 810A can allow the oxygen from the first storage space 110A to enter the gas collection chamber 810A through the air inlet 811A, and allow the collected oxygen to flow to the second storage space 120A through the gas outlet 812A.

Since the oxygen collecting part 800A can allow the oxygen from the first storage space 110A to enter the gas collection chamber 810A, and allow the oxygen in the gas collection chamber 810A to flow to the second storage space 120A, the oxygen is equivalent to being transferred from the first storage space 110A to the second storage space. The storage space 120A, therefore the oxygen collection component 800A can make the refrigerator 10A adjust the oxygen content of multiple storage spaces through the transfer of oxygen, skillfully balancing the oxygen supply and demand relationship of multiple storage spaces.

In some optional embodiments, the refrigerator 10A may further include an oxygen delivery pipe 910A, connected between the second storage space 120A and the gas outlet 812A of the gas collection chamber 810A, configured to guide the oxygen flowing out of the gas outlet 812A to Lead to the second storage space 120A.

The oxygen delivery pipe 910A is used to connect the second storage space 120A with the gas collection chamber 810A. The distance between the oxygen collection part 800A and the second storage space 120A is adjustable, and can be set at any position away from or close to the second storage space 120A.

By installing the oxygen delivery pipe 910A, the installation location of the oxygen collection component 800A can be very flexible, without being limited to the installation location of the second storage space 120A. The oxygen collection component 800A can be placed anywhere away from the second storage space 120A, such as in the air duct, in the foam material, or in the press chamber, and can also be placed outside the box 100A, such as the top of the box 100A. When the oxygen collecting part 800A is arranged at the above position, it is not easy to be touched by the user, and it will not occupy the storage space of the refrigerator 10A, which can not only ensure the safety, but also ensure the volume ratio.

In some optional embodiments, the refrigerator 10A may further include an air flow direction adjustment member 920A, which is disposed on the oxygen delivery pipe 910A and configured to allow the oxygen from the gas collection chamber 810A to pass through in one direction. That is, the airflow direction adjuster 920A is used to adjust the direction in which the airflow passes. For example, the airflow direction regulator 920A may be a one-way valve.

Due to the diffusivity of the gas, the gas flow direction regulator 920A is used to make the oxygen flow to the gas collection chamber 810A only in one direction, so as to avoid the backflow of oxygen, thereby ensuring the high oxygen supply efficiency of the gas collection chamber 810A.

In some optional embodiments, the refrigerator 10A may further include a gas treatment device 200A, which has an electrode assembly, It is configured to separate the oxygen in the first storage space 110A through an electrochemical reaction, thereby reducing the oxygen content in the first storage space 110A. That is to say, the gas treatment device 200A can perform oxygen removal work through an electrochemical reaction, so that the first storage space 110A creates a low-oxygen fresh-keeping atmosphere.

The gas inlet 811A of the gas collection chamber 810A communicates with the gas processing device 200A, and is configured to collect the oxygen separated by the gas processing device 200A. For example, the gas treatment device 200A may have an exhaust port for exhausting the separated oxygen. The gas inlet 811A of the gas collection chamber 810A can communicate with the gas outlet of the gas treatment device 200A.

Since the oxygen collection part 800A can collect the oxygen separated by the gas processing device 200A when the gas processing device 200A performs the deoxygenation work, the oxygen, as a by-product of the gas processing device 200A, can be sent to a specific storage space (such as the first) by the oxygen collection part 800A. Two storage spaces 120A) are provided and reused. Therefore, based on the solution of this embodiment, the refrigerator 10A can satisfy different oxygen requirements of multiple different storage spaces with less energy consumption.

In some optional embodiments, the refrigerator 10A may further include an oxygen supply pipe 930A, which is connected between the air inlet 811A of the gas collection chamber 810A and the gas processing device 200A, and is configured to separate the gas processing device 200A from The oxygen is directed to the plenum 810A. For example, the oxygen supply pipe 930A may be connected between the gas inlet 811A of the gas collection chamber 810A and the gas outlet of the gas treatment device 200A.

The oxygen supply pipe 930A is used to connect the gas treatment device 200A and the gas collection chamber 810A, the distance between the oxygen collection part 800A and the second storage space 120A is adjustable, and can be set at any position away from or close to the second storage space 120A.

By installing the oxygen supply pipe 930A, the installation location of the oxygen collection component 800A can be very flexible, without being limited to the installation location of the gas treatment device 200A and the first storage space 110A. The oxygen collection component 800A can be arranged at any position away from the gas collection device and the first storage space 110A, such as in the air duct, in the foam material or in the press chamber, etc., and can also be arranged outside the box body 100A, such as the box body 100A top etc. The oxygen collecting part 800A will not occupy the storage space of the refrigerator 10A, which can not only ensure the safety, but also ensure the volume ratio.

In some optional embodiments, the refrigerator 10A may further include a gas flow actuator 940A, which is disposed on the oxygen supply pipe 930A and is configured to facilitate the flow from the gas treatment device 200A to the gas inlet 811A of the gas collection chamber 810A. airflow.

Under the action of the gas flow actuator 940A, the oxygen separated by the gas processing device 200A can be quickly enriched in the gas collection chamber 810A, and at the same time, the gas processing device 200A can be promoted to improve the electrochemical reaction efficiency.

In some optional embodiments, the refrigerator 10A may further include an oxygen buffer component 950A, and it has a buffer cavity 951A communicating with the oxygen supply pipe 930A, configured to allow flow through the oxygen supply pipe when the airflow actuator 940A is closed. Oxygen from 930A flows into it.

In this embodiment, the buffer chamber 951A may be disposed upstream of the airflow actuator 940A. In this way, when the air flow actuator 940A is activated, almost no oxygen will be enriched in the buffer chamber 951A, and the oxygen separated by the gas processing device 200A can be quickly enriched into the gas collection chamber 810A.

In some embodiments, the airflow actuator 940A can be controlled closed when the plenum 810A is filled with oxygen. When the gas flow actuator 940A is closed, the buffer chamber 951A can be used as a temporary oxygen collection area to quickly remove the oxygen separated by the gas treatment device 200A. In this way, it is possible to reduce or avoid the failure of the electrochemical reaction due to the inability to discharge the by-products of the gas treatment device 200A.

In some optional embodiments, the refrigerator 10A may further include: a heating component 960A disposed on the oxygen delivery pipe 910A and configured to heat the oxygen delivery pipe 910A. The heating element 960A may be an electric heating element, such as an electric heating wire, an electric heating sheet or an electric heating block, etc., configured to generate electricity and generate heat, thereby heating the oxygen delivery pipe 910A.

Utilizing the heating element 960A to heat the oxygen delivery pipe 910A can prevent the oxygen delivery pipe 910A from being blocked due to frost condensation and keep it unblocked.

FIG. 2 is a schematic structural diagram of a gas treatment device 200A of a refrigerator 10A according to an embodiment of the present invention.

In some optional embodiments, the electrode assembly includes a cathode 210A and an anode 220A, the cathode 210A is configured to consume oxygen in the first storage space 110A through an electrochemical reaction, and the anode 220A is configured to provide reactants to the cathode 210A through an electrochemical reaction and Oxygen is generated, thereby separating the oxygen in the first storage space 110A.

An electrolysis chamber 240A is formed inside the gas processing device 200A. The electrolysis chamber 240A can contain an alkaline electrolyte, such as 0.1-8 mol/L NaOH or KOH, and its concentration can be adjusted according to actual needs.

In some optional embodiments, for example, oxygen in the air can undergo a reduction reaction at the cathode 210A, namely: O ₂ +2H ₂ O+4e ⁻ →4OH ⁻ . The OH ⁻ produced by the cathode 210A can undergo an oxidation reaction at the anode 220A to generate oxygen, namely: 4OH ⁻ →O ₂ +2H ₂ O+4e ⁻ . The anode 220A provides reactants, such ^as electrons e − , to the cathode 210A while utilizing OH ⁻ to undergo an electrochemical reaction.

With the above structure, the gas processing device 200A can process the oxygen in the first storage space 110A, so as to conform to the development concept of low-oxygen freshness preservation, prolong the shelf life of fruits and vegetables and other food materials, and improve the freshness preservation performance of the refrigerator 10A. At the same time, because the anode 220A generates oxygen during the electrochemical reaction, this part of oxygen can be utilized under the action of the oxygen collection part 800A, for example, it can be transported to The second storage space 120A can improve the air-conditioning capability of the refrigerator 10A, so that it can simultaneously create a low-oxygen fresh-keeping atmosphere and a high-oxygen fresh-keeping atmosphere.

The cathode 210A and the anode 220A respectively include multi-segment electrode plates, and respectively jointly surround a hollow cylinder, such as a hollow cylinder or a hollow prism. Wherein, the hollow prism may be a triangular prism, a quadrangular prism, a pentagonal prism, or a hexagonal prism, and is preferably a quadrangular prism.

The hollow cylinder where the cathode 210A is located is nested inside the hollow cylinder where the anode 220A is located. An electrolysis chamber 240A is formed between the cathode 210A and the anode 220A. The side of the cathode 210A facing away from the anode 220A forms a processing air channel 230A in air flow communication with the first storage space 110A, so that the oxygen in the gas flowing through the processing air channel 230A contacts with the cathode 210A.

In this embodiment, the processing air channel 230A has a definite air inlet end 231A and an air outlet end 232A, and extends from the air inlet end 231A to the air outlet end 232A. The gas to be treated can flow along the extension direction of the processing air duct 230A, and during the flow, the oxygen in the gas continuously participates in the electrochemical reaction and is consumed, which can make the gas flowing out of the processing air duct 230A contain very little Oxygen, which is conducive to strengthening the effect of air conditioning, reducing the time required for air conditioning, and reducing the number of airflow cycles. Only one or a small number of gas flow cycles between the first storage space 110A and the gas treatment device 200A may be needed to meet the oxygen reduction requirement of the first storage space 110A.

In some optional embodiments, the gas treatment device 200A further includes a first protective frame 261A and a second protective frame 262A. Wherein, the first protective frame 261A is in the shape of a hollow column, and is sheathed outside the hollow column where the anode 220A is located. The second protective frame 262A is also in the shape of a hollow column, and is sheathed inside or outside of the hollow column where the cathode 210A is located. And the first protective frame 261A and the second protective frame 262A close the gap between the anode 220A and the cathode 210A.

The anode 220A and the cathode 210A are respectively protected by the first protective frame 261A and the second protective frame 262A, which can improve the structural strength of the gas treatment device 200A to a certain extent, and reduce or avoid electrolyte leakage.

In some optional embodiments, the refrigerator 10A may further include an air intake component 310A and a return air component 320A. Wherein, the air intake component 310A communicates with the air intake end 231A of the processing air duct 230A and the first storage space 110A, and is configured to deliver the airflow from the first storage space 110A to the processing air duct 230A. The return air component 320A communicates with the air outlet 232A of the processing air duct 230A and the first storage space 110A, and is configured to transport the airflow treated by the cathode 210A to the first storage space 110A.

By arranging the air intake part 310A and the air return part 320A, and connecting the air intake part 310A and the air return part 320A to the air intake end 231A and the air outlet end 232A of the processing air duct 230A respectively, the first storage space 110A and the cathode can be The air circulation channel is formed, which is conducive to improving the air circulation of the air conditioning process and optimizing the air conditioning efficiency.

Since the air to be processed flows to the processing air duct 230A through the air intake part 310A, and the processed air returns to the storage space 120A through the air return part 320A, the air intake part 310A is set independently from the return air part 320A, "to be processed Airflow" and "processed airflow" will not significantly mix, which can reduce or prevent the treated airflow from being mixed into the airflow to be treated, thereby ensuring the efficiency of air conditioning.

In some embodiments, the air intake component 310A and the return air component 320A may be air delivery pipes respectively, but are not limited thereto. An air flow actuating device (for example, an oxygen-reducing blower 330A) may be provided in the gas delivery pipe where the air intake component 310A is located, for promoting the formation of air flow from the first storage space 110A to the air intake component 310A, and through the processing air duct 230A, The air return component 320A then returns to the airflow of the first storage space 110A, so as to improve the air conditioning efficiency.

In some optional embodiments, the first storage space 110A of the refrigerator 10A may be provided with an anti-condensation device, which may generally include a moisture-permeable film 610A, and the moisture-permeable film 610A allows the moisture in the hypoxic first storage space 110A to Water vapor passes in one direction. The anti-condensation device may also include a dehumidification fan 620A, which is used to increase the air velocity near the moisture-permeable membrane 610A, so as to promote the rapid discharge of water vapor in the first storage space 110A.

Fig. 3 is a schematic structural view of a refrigerator 10A according to an embodiment of the present invention, and Fig. 4 is a partial enlarged view of A in Fig. 3 .

When the hollow quadrangular prism where the cathode 210A is located is nested outside the hollow cylinder where the anode 220A is located, the gas treatment device 200A may also have a hollow cylindrical shell 250A, which is packaged outside the hollow cylinder where the cathode 210A is located, and The gap between the hollow cylinders where the cathode 210A is located encloses the processing air channel 230A. An air inlet and an air outlet are provided on the hollow cylindrical housing 250A, respectively, as the air inlet 231A and the air outlet 232A. In this embodiment, the air inlet and the air outlet are arranged away from each other to extend the air path of the processing air duct 230A.

In some optional embodiments, the refrigerator 10A may further include a liquid quality adjustment tank 510A.

The liquid quality regulating tank 510A is configured to store the electrolyte to replenish the electrolytic chamber 240A, thereby adjusting the liquid quality of the electrolyte in the electrolytic chamber 240A. The liquid quality of the electrolyte refers to the quality of the electrolyte, that is, the liquid volume and concentration of the electrolyte. The electrolyte solution stored in the liquid quality adjustment tank 510A may be consistent with the electrolyte solution contained in the electrolysis chamber 240A.

The refrigerator 10A of this embodiment is provided with a liquid quality adjustment tank 510A, when using the electrolyte stored in the liquid quality adjustment tank 510A to replenish the electrolytic chamber 240A of the gas processing device 200A, water can be replenished to the electrolytic chamber 240A , and electrolyte can be replenished to the electrolytic chamber 240A, therefore, the loss of the electrolyte can be fully compensated, the liquid quality of the electrolyte in the electrolytic chamber 240A can be better adjusted, the effect of liquid replenishment can be improved, and the "quantity" and "quality" of the electrolyte can be improved. Recover as much as possible and maintain the original state.

Use the electrolyte stored in the liquid quality adjustment tank 510A to replenish the electrolytic chamber 240A, so that the lost substances of the electrolyte can be replenished in time. Compared with the scheme of simply replenishing water to the electrolytic chamber 240A, the refrigerator 10A and the gas treatment device 200A of this scheme The electrolyte concentration in a There will be no obvious drop phenomenon within a certain period of time, so the gas treatment device 200A can maintain a good gas-conditioning efficiency for a long time.

Since the liquid quality adjustment tank 510A can store electrolyte in advance, when it is necessary to replenish the electrolytic chamber 240A, it is only necessary to connect the liquid path between the liquid quality adjustment tank 510A and the electrolytic chamber 240A. fluid, which is conducive to improving the safety of the fluid rehydration process.

Since the liquid quality adjustment tank 510A is used to replenish the electrolytic chamber 240A, the electrolyte of the gas treatment device 200A can be maintained at its initial state. Therefore, there is no need to over-consider the electrolyte loss problem, and it is not necessary to "pre-install" in the electrolytic chamber 240A The electrolyte with a higher concentration is beneficial to reduce the packaging difficulty of the gas processing device 200A and reduce the manufacturing cost. The electrolytic chamber 240A only needs to be pre-filled with an electrolyte with a suitable concentration, and the packaging shell of the gas processing device 200A does not need to use materials with high corrosion resistance.

The inventors of the present application creatively set a liquid quality regulating box 510A on the refrigerator 10A to adjust the liquid quality of the electrolyte in the electrolytic chamber 240A. The problem provides a new idea, and at the same time solves many technical problems such as the difficulty of packaging the gas processing device 200A, which serves multiple purposes.

In some optional embodiments, the refrigerator 10A may further include a transfusion tube 530A. The infusion tube 530A is connected between the electrolysis chamber 240A and the liquid quality adjustment tank 510A, and is configured to transport the electrolyte contained in the liquid quality adjustment tank 510A to the electrolysis chamber 240A.

In some further embodiments, the refrigerator 10A may further include a power component 520A. The power unit 520A is arranged on the infusion tube 530A and is configured to be activated under control to promote the flow of electrolyte from the liquid quality adjustment tank 510A to the electrolysis chamber 240A. That is to say, the power component 520A is used to provide power for liquid flow. Under the action of the power component 520A, the electrolyte in the liquid quality adjustment tank 510A flows through the infusion tube 530A and then flows to the electrolysis chamber 240A.

By installing the infusion tube 530A and the power component 520A, the installation location of the liquid quality adjustment tank 510A can be very flexible, and is not limited to the installation location of the gas treatment device 200A. The liquid quality adjustment tank 510A can be set anywhere away from the storage space 120A, such as in the air duct, foam material or press chamber, etc., and can also be set outside the box 100A, such as the top of the box 100A. When the liquid quality adjustment box 510A is set at the above position, it is not easy to be touched by the user, and it will not occupy the storage space 120A of the refrigerator 10A, which can not only ensure the safety, but also ensure the volume ratio.

In some optional embodiments, the refrigerator 10A may further include a liquid return pipe 540A, which communicates between the liquid quality adjustment tank 510A and the electrolysis chamber 240A, and is set independently from the infusion pipe 530A, and is configured to be connected to the power unit 520A. When starting, the electrolyte is made to flow from the electrolysis chamber 240A to the liquid quality adjustment tank 510A to form an electrolyte circulation flow path. That is, there are two pipes connected between the liquid quality adjustment tank 510A and the electrolysis chamber 240A, one is an infusion pipe 530A, and the other is a liquid return pipe 540A, and the electrolyte in the liquid quality adjustment tank 510A flows into the electrolysis chamber from the infusion pipe 530A 240A, the electrolyte in the electrolysis chamber 240A flows into the liquid quality adjustment tank 510A from the liquid return pipe 540A. That is, the liquid quality adjustment tank 510A, the infusion tube 530A, the electrolysis chamber 240A, the liquid return pipe 540A, and the liquid quality adjustment tank 510A are connected in sequence to form an electrolyte circulation flow path.

By installing the liquid return pipe 540A, the liquid infusion pipe 530A and the power unit 520A, when the liquid quality adjustment tank 510A is used to replenish the electrolytic chamber 240A, if the electrolytic chamber 240A is filled with electrolyte, the excess electrolyte will flow through the liquid return pipe 540A. Return to the liquid quality adjustment tank 510A, and will not cause overflow or leakage. Therefore, the refrigerator 10A of this embodiment does not need to install a liquid level sensor in the electrolytic chamber 240A to detect whether the electrolytic chamber 240A is filled with electrolyte, nor does it need to control the liquid replenishment process according to the detection result of the liquid level sensor, which not only simplifies the hardware structure, and simplifies the control logic.

For example, based on the structure of the present embodiment, when replenishing fluid, the working time of the power component 520A is preset, and the starting time of the power component 520A is counted to determine when to stop the fluid replenishment.

It needs to be further explained that, when determining when to end the rehydration during the rehydration process, under the constraints of "automation" and other ideas, those skilled in the art can easily think of using a liquid level sensor to detect the liquid level. However, since the electrolyte is corrosive, the cost of installing a corrosion-resistant liquid level sensor in the electrolytic chamber 240A is very high. However, based on the solution of this embodiment, the refrigerator 10A does not need to accurately determine when to end the liquid replenishment, which not only cleverly avoids installing a liquid level sensor, but also solves the risk of overflow and leakage, and has a good application prospect.

In some optional embodiments, the power component 520A is a pump, such as a micro water pump, but not limited thereto. The power component 520A is configured to cut off the infusion tube 530A in the closed state. That is, the power unit 520A allows the electrolyte to flow from the liquid quality regulating tank 510A into the infusion tube 530A and into the electrolysis chamber 240A only after the controlled activation.

Fig. 5 is a schematic structural view of a refrigerator 10A according to another embodiment of the present invention, in which the cabinet 100A is omitted. In some optional embodiments, the refrigerator 10A may further include a water tank 710A, a water delivery pipe 720A and a switch element 730A.

Wherein, the water tank 710A is configured to contain water to replenish water to the liquid quality adjustment tank 510A. The water delivery pipe 720A is connected between the water tank 710A and the liquid quality adjustment tank 510A, and is configured to deliver the water contained in the water tank 710A to the liquid quality adjustment tank 510A. The switch element 730A is disposed on the water delivery pipe 720A, and is configured to be opened and closed in a controlled manner to switch the water delivery pipe 720A. The switch element 730A can be a solenoid valve or a manual switch valve or the like.

The inventors further realized that during the loss of electrolyte in the electrolytic chamber 240A, the water loss rate is greater than the electrolyte loss rate. As the use time continues to prolong, the concentration of the electrolyte in the electrolysis chamber 240A and the liquid quality adjustment tank 510A will increase. The switch element 730A, and the water delivery pipe 720A communicates with the water tank 710A and the liquid quality adjustment tank 510A, can directly and appropriately adjust the electrolyte concentration of the liquid quality adjustment tank 510A, thereby indirectly adjusting the electrolyte concentration in the electrolytic chamber 240A, making it return to the initial level.

In some optional embodiments, a flow sensor 740A may be provided in the water delivery pipe 720A for detecting the flow of the liquid.

FIG. 6 is a schematic structural view of a refrigerator 10B according to an embodiment of the present invention. The refrigerator 10B in this embodiment should be understood in a broad sense, for example, it can be a refrigerator, a freezer, a storage cabinet and other storage equipment with a low-temperature preservation function.

The refrigerator 10B may generally include a cabinet 100B and a gas handling device 200B. The case 100B is omitted in FIG. 6 . Wherein, a storage space 120B is formed inside the box body 100B. The storage space 120B in this embodiment should be understood broadly. For example, the storage space 120B may refer to an inner space of a storage compartment, or an inner space of a storage container disposed in the storage compartment, or a peripheral environmental space formed in the storage compartment and located outside the storage container.

The gas processing device 200B has a processing part 210B and a processing air channel 230B, wherein the processing part 210B is configured to process specific gas components in the storage space 120B. The processing air duct 230B is in air flow communication with the storage space 120B, and is used to make the gas from the storage space 120B flow through the processing part 210B. That is to say, the processing air passage 230B in this embodiment acts as a guide, and the gas from the storage space 120B flows through the processing part 210B under the guidance of the processing air passage 230B. The processing part 210B increases or decreases the content of the specific gas component by processing the specific gas component.

In the refrigerator 10B of this embodiment, since the gas processing device 200B is formed with a processing part 210B and a processing air channel 230B, the processing air channel 230B can allow the gas from the storage space 120B to flow through the processing part 210B, so that the processing part 210B can process the specific gas in the gas. Therefore, when it is necessary to adjust the gas environment of the storage space 120B, it is only necessary to connect the storage space 120B with the processing channel, and it is not necessary to arrange the entire gas treatment device 200B at the gas-permeable area of the storage space 120B. The gas treatment device 200B may be installed in other locations away from storage space 120B.

According to the solution of this embodiment, by improving the air flow communication mode between the storage space 120B and the gas processing device 200B, it is possible to realize the modified atmosphere preservation without affecting the volume ratio of the refrigerator 10B.

The flow path of the gas to be processed in the gas processing device 200B forms a processing air channel 230B. Since the processing air passage 230B can make the gas from the storage space 120B flow through the processing part 210B, the processing air passage 230B can fully contact the gas with the processing part 210B during the process of guiding the gas. Based on the guiding effect of the processing air passage 230B, Refrigerator 10B can obtain higher air conditioning efficiency.

The manner in which the processing unit 210B processes the specific gas component and the type of the specific gas component can be set according to actual needs. For example, the processing unit 210B may process specific gas components by means of adsorption, reduction, or oxidation. Among them, reduction and oxidation can be carried out by means of electrochemical reactions. The specific gas component may be oxygen.

Of course, the above examples are only illustrative. On the basis of understanding these embodiments, those skilled in the art should easily expand and transform the refrigerator 10B of this embodiment, and handle other types of specific gas components, such as using Electrochemical reactions for producing or consuming carbon dioxide, electrochemical reactions for producing or consuming nitrogen, reactions for producing or consuming ethylene, etc., these expansions should all fall within the protection scope of the present invention.

In some optional embodiments, the processing part 210B is disposed in the processing air channel 230B or forms at least a part of the air channel wall of the processing air channel 230B. Thus, it can be fully ensured that the gas can flow through the processing part 210B when flowing through the processing air channel 230B.

In some optional embodiments, the gas processing device 200B is an electrolysis device, and the processing unit 210B is a cathode electrode of the gas processing device 200B, configured to process specific gas components in the storage space 120B through an electrochemical reaction. The gas treatment device 200B also has a matching portion 220B, which is an anode electrode opposite to a cathode electrode. The anode electrode is configured to provide reactants to the cathode electrode through an electrochemical reaction.

The structure of the refrigerator 10B will be further introduced below by taking the case where the specific gas component is oxygen as an example.

For example, oxygen in the air can undergo a reduction reaction at the cathode electrode, namely: O ₂ +2H ₂ O+4e ⁻ →4OH ⁻ . The OH ^- generated at the cathode electrode can undergo oxidation reaction at the anode electrode and generate oxygen, namely: 4OH ^- → O ₂ +2H ₂ O + 4e ^- . The anode electrode provides reactants, such as electrons e ^- , to the cathode electrode while utilizing OH ^- for electrochemical reaction. That is, the processing unit 210B is configured to consume oxygen in the storage space 120B through an electrochemical reaction. The cooperating part 220B is configured to provide reactants to the processing part 210B through an electrochemical reaction, and generate oxygen gas.

In some optional embodiments, the storage space of the refrigerator 10B can be provided with an anti-condensation device, which generally can include a moisture-permeable film 610B, and the moisture-permeable film 610B allows the water vapor in the hypoxic storage space 120B to pass through in one direction. . The anti-condensation device can also include a dehumidification fan 620B, used to increase the air flow rate near the moisture-permeable membrane 610B, so that the water vapor in the hypoxic storage space 120B can be quickly discharged.

In some optional embodiments, the refrigerator 10B further includes a liquid replenishment container 510B, which forms a liquid storage space in communication with the electrolysis chamber 240B for replenishing liquid (such as water or electrolyte) to the electrolysis chamber 240B. For example, the liquid replenishment container 510B can be a water tank, and a liquid supply port is opened on it, and a liquid inlet port is correspondingly opened on the electrolysis chamber 240B. The infusion tube is communicated so that the liquid from the outflow supply port is guided to the liquid inlet port by the infusion tube. A switch element 520B may be installed on the infusion tube for controlled opening and closing, thereby switching on and off the liquid path between the liquid supply port and the liquid inlet port.

In some optional embodiments, a flow sensor 530B may be provided in the infusion tube for detecting the flow of the liquid.

In some optional embodiments, the processing part 210B and the matching part 220B are hollow cylinders, such as cylinders or prisms, respectively. In addition, the processing part 210B and the matching part 220B are nested with each other. The gap between the processing part 210B and the matching part 220B forms an electrolytic chamber 240B for containing electrolyte. When the processing part 210B and the fitting part 220B are respectively hollow prisms, they can be triangular prisms, quadrangular prisms, pentagonal prisms or hexagonal prisms, preferably quadrangular prisms. The quadrangular prism has high symmetry and a relatively simple electrode structure, which can fully meet the air conditioning requirements of the existing refrigerator 10B.

Fig. 9 is a schematic structural diagram of a gas processing device 200B of a refrigerator 10B according to an embodiment of the present invention, and Fig. 10 is a schematic structural diagram of a gas processing device 200B of a refrigerator 10B according to another embodiment of the present invention, in which The case where the processing part 210B and the matching part 220B are respectively hollow quadrangular prisms is shown.

The processing part 210B and the matching part 220B are used to form hollow columnar electrodes nested in each other, and the gas can be processed based on the electrochemical reaction of the electrodes. Since the processing part 210B and the matching part 220B have a larger electrode area, the limited volume can be used to improve the gas treatment. The electrochemical reaction rate of the device 200B enables the gas processing device 200B to have the advantages of high gas conditioning efficiency and miniaturization.

When the processing part 210B and the matching part 220B are hollow cylinders, the gas processing device 200B has an arc-shaped curved surface structure, which creatively provides a new gas processing device 200B with a unique shape and structure, which breaks through the straight structure of the refrigerator 10B The thought shackles of layout. Based on the electrode with arc-shaped curved surface structure, the gas processing device 200B can fully contact the electrode with the gas to be processed by virtue of a small volume, thereby improving the gas-conditioning efficiency. The unique shape makes the gas treatment device 200B suitable for installation in certain specific spaces, such as the compressor chamber or air duct of the refrigerator 10B, which is beneficial to increase the diversity of installation positions of the gas treatment device 200B.

Oxygen is also generated during the electrochemical reaction of the matching part 220B, therefore, in some further embodiments, the gas treatment device 200B also has an exhaust part 260B configured to exhaust the oxygen generated by the matching part 220B into the box 100B Other storage space 120B. For example, the gas treatment device 200B may be provided with an exhaust port communicating with the electrolysis chamber 240B, so as to allow the oxygen generated by the matching part 220B to be exhausted.

In some optional embodiments, the refrigerator 10B may further include an air intake component 310B and an air return component 320B. Wherein, the air intake component 310B communicates with the air intake end 231B of the processing air duct 230B and the storage space 120B, and is configured to deliver the airflow from the storage space 120B to the processing air duct 230B. The return air component 320B communicates with the air outlet 232B of the processing air duct 230B and the storage space 120B, and is configured to transport the airflow processed by the processing unit 210B to the storage space 120B.

By arranging the air intake part 310B and the air return part 320B, and connecting the air intake part 310B and the air return part 320B to the air intake end 231B and the air outlet end 232B of the processing air duct 230B respectively, the storage space 120B and the processing part 210B can be separated. The air circulation channel is formed, which is conducive to improving the air circulation of the air conditioning process and optimizing the air conditioning efficiency.

Since the air flow to be processed flows to the processing channel through the air intake component 310B, and the processed air flow returns to the storage space 120B through the return air component 320B, the air intake component 310B and the return air component 320B are set independently, and the “air flow to be processed” There will be no obvious mixed flow with the "processed airflow", which can reduce or prevent the treated airflow from being mixed into the untreated airflow, thereby ensuring the air conditioning efficiency.

In some embodiments, the air intake component 310B and the return air component 320B may be air delivery pipes respectively, but are not limited thereto. The air delivery pipe where the air intake part 310B is located can be connected with an airflow actuation device (such as an oxygen reduction fan 330B), which is used to promote the formation of a flow from the storage space 120B to the air intake part 310B, and through the processing air duct 230B, return air part After 320B, return to the airflow of the storage space 120B to improve the air conditioning efficiency.

In some optional embodiments, the hollow cylinder where the processing part 210B is located is nested inside the hollow cylinder where the matching part 220B is located. And the processing air channel 230B is formed inside the hollow cylinder where the processing part 210B is located. The inner side of the hollow cylinder where the treatment part 210B is located refers to the side of the treatment part 210B facing away from the matching part 220B.

At this time, the processing air channel 230B has a definite air inlet end 231B and an air outlet end 232B, and extends from the air inlet end 231B to the air outlet end 232B. The gas to be treated can flow along the extension direction of the processing air channel 230B. During the flow, the specific gas components in the gas continuously participate in the electrochemical reaction and are consumed, which can make the gas flowing out of the processing air channel 230B contain Very few specific gas components strengthen the effect of air conditioning, reduce the time required for air conditioning, and reduce the number of airflow cycles. Only one or a small number of airflow cycles between the storage space 120B of the refrigerator 10B and the gas processing device 200B may be needed to meet the oxygen reduction requirement of the storage space 120B.

In other optional embodiments, the hollow cylinder where the processing part 210B is located is nested outside the hollow cylinder where the matching part 220B is located. And the processing air channel 230B is formed outside the hollow cylinder where the processing part 210B is located. The outside of the hollow cylinder where the treatment part 210B is located refers to the side of the treatment part 210B facing away from the matching part 220B.

At this time, the processing part 210B can obtain a larger electrode plate area, and the processing air channel 230B can provide a larger gas flow space, and the processing part 210B can fully contact with the gas to be processed, so the gas flow of the processing part 210B can be effectively improved. Tuning rate.

When the hollow cylinder where the processing part 210B is located is nested outside the hollow cylinder where the matching part 220B is located, in some optional embodiments, as shown in FIG. It is packaged on the outside of the processing part 210B, and the gap between the processing part 210B and the processing part 210B encloses a processing air channel 230B. An air inlet and an air outlet are respectively provided on the hollow cylindrical shell 250B, which serve as the air inlet 231B and the air outlet 232B respectively. In this embodiment, the air inlet and the air outlet are arranged away from each other to extend the air path of the processing air duct 230B.

In some optional embodiments, the processing part 210B and the matching part 220B respectively include a plurality of electrode plates, and respectively enclose a hollow cylinder together.

In some optional embodiments, the multi-segment electrode plates of the processing part 210B and the matching part 220B can be integrated or separated. Wherein, "discrete parts" refer to components that are independently arranged, which is opposite to the concept of "integrated molding" referred to by "integrated parts".

When the processing part 210B and the mating part 220B are one piece, the plate-shaped electrodes can be bent to form multiple electrode plates with different orientations, or multiple electrode plates with different orientations can be obtained directly through the forming process. When the treatment part 210B and the matching part 220B are separate parts, the multi-segment electrode plates are spliced to form the hollow cylindrical treatment part 210B and the matching part 220B, and there may be gaps between adjacent electrode plates.

Using discrete electrode plates to form the electrodes can flexibly arrange the positions and orientations of the electrode plates of the processing part 210B and the matching part 220B, so that the structure of the gas processing device 200B can be diversified and refined, and it is convenient for multiple devices with a specific spatial layout. The storage space 120B is subjected to controlled atmosphere treatment without complicated bending process or forming process, and has the advantage of simple process.

When the hollow cylinder where the processing part 210B is located is nested outside the hollow cylinder where the matching part 220B is located, in some optional embodiments, the gas treatment device 200B further includes a first protective frame 261B and a second protective frame 262B. Wherein, the first protective frame 261B is in the shape of a hollow cylinder, and is sheathed outside the hollow cylinder where the treatment part 210B is located. The second protective frame 262B is also in the shape of a hollow prism, and is sleeved on the inside or outside of the hollow cylinder where the matching portion 220B is located. And the first protective frame 261B and the second protective frame 262B close the gap between the processing part 210B and the matching part 220B.

The first protective frame 261B and the second protective frame 262B are respectively used to protect the processing part 210B and the matching part 220B, which can improve the structural strength of the gas processing device 200B to a certain extent, and reduce or avoid electrolyte leakage. In some further embodiments, the first protective frame 261B may be provided with ventilation holes for allowing gas to pass through, so as to avoid completely covering the treatment part 210B and ensure the normal operation of the controlled atmosphere process.

It should be noted that when the multi-segment electrode plates of the processing part 210B and the matching part 220B can be discrete parts, the first protective frame 261B and the second protective frame 262B also play an integrated role, respectively making the discrete processing part 210B and the matching part The multi-segment electrode plates of section 220B are assembled into one body.

When the hollow cylinder where the matching part 220B is located is nested outside the hollow cylinder where the processing part 210B is located, the first protective frame 261B can be converted to be sleeved outside the hollow cylinder where the matching part 220B is located, and the second protective frame 262B can be transformed into It is sleeved on the inside or outside of the hollow cylinder where the treatment part 210B is located.

In the refrigerator 10B in the above embodiments, the gas processing device 200B can process specific gas components of one or more storage spaces 120B. When it is necessary to process specific gas components in multiple storage spaces 120B, multiple sets of air intake components 310B and return air components 320B need to be installed separately, and multiple sets of intake components 310B and return air components 320B are connected to the storage spaces 120B one by one. Corresponding communication, each set of air intake component 310B and return air component 320B is used to construct an air circulation channel that communicates with the corresponding storage space 120B and the processing air channel 230B.

In some optional embodiments, when it is necessary to treat specific gas components of the multiple storage spaces 120B, the gas treatment device 200B may be arranged between the multiple storage spaces 120B.

For example, when the processing part 210B and the matching part 220B respectively surround a hollow quadrangular prism, and the hollow quadrangular prism where the processing part 210B is located is sleeved outside the hollow quadrangular prism where the matching part 220B is located, since the two pole plates of the processing part 210B When the gas processing device 200B is arranged between two storage spaces 120B arranged side by side, each storage space 120B can be opposite to a pole plate of the processing part 210B, and the unique structure of the gas processing device 200B can be compared with a refrigerator. The layout structure of the 10B storage space 120B is perfectly matched, and the structure is ingenious, which is beneficial to reduce the gas path structure and optimize the space layout of the refrigerator 10B.

For example, in some optional embodiments, the storage space 120B includes a first fresh-keeping space and a second fresh-keeping space. The processing part 210B includes a first fresh-keeping plate section and a second fresh-keeping plate section.

Of course, the spatial layout of the refrigerator 10B is not limited to this. For example, in other optional embodiments, the first fresh-keeping space and The second fresh-keeping space is juxtaposed up and down. The hollow quadrangular prism where the processing part 210B is located is arranged between the first fresh-keeping space and the second fresh-keeping space, and the first fresh-keeping plate section and the second fresh-keeping plate section are distributed on the upper and lower sides of the hollow quadrangular prism, so as to be connected with The first fresh-keeping space is in airflow communication with the second fresh-keeping space.

In the refrigerator 10B of the present invention, since the gas processing device 200B is formed with a processing part 210B and a processing air channel 230B, the processing air channel 230B can allow the gas from the storage space 120B to flow through the processing part 210B, so that the processing part 210B can treat specific gases in the gas. Therefore, when it is necessary to adjust the gas environment of the storage space 120B, it is only necessary to connect the storage space 120B with the processing channel, and it is not necessary to arrange the entire gas treatment device 200B at the gas-permeable area of the storage space 120B. The gas treatment device 200B It may be installed in other locations away from the storage space 120B. According to the solution of the present invention, by improving the air flow communication mode between the storage space 120B and the gas processing device 200B, it is possible to realize the modified atmosphere preservation without affecting the volume ratio of the refrigerator 10B.

FIG. 11 is a schematic block diagram of a refrigerator 10C according to one embodiment of the present invention. The refrigerator 10C may generally include a box body 100C, a gas treatment device 200C, and a gas circuit assembly 300C.

Wherein, the inside of the box body 100C defines a storage space for storing items, such as foodstuffs, medicines, and the like. The storage space may refer to the internal space of a storage compartment (such as a refrigerator compartment, a freezer compartment, etc.), or may refer to the interior of a storage container (such as a storage drawer, a storage basket, etc.) arranged in the storage space space.

The gas treatment device 200C is arranged in the box body 100C and has a treatment unit 220C. The treatment unit 220C is in gas flow communication with the storage space, and is used to treat a specific gas component in the storage space, for example, to reduce the content of a specific gas component, or to increase a specific gas component. content of gas components.

The air path assembly 300C has an air flow processing channel 310C communicating with the processing portion 220C and the storage space. Under the guidance of the air circuit assembly 300C, the air in the storage space can flow through the airflow processing channel 310C and flow to the processing part 220C, and then return to the storage space after being processed by the processing part 220C.

The gas flow processing channel 310C has an air intake section 312C and a return air section 314C. The air intake section 312C is connected between the storage space and the processing part 220C, and is used to transport the airflow from the storage space to the processing part 220C, and the air return section 314C is connected between the processing part 220C and the storage space, and is used to transfer the airflow from the storage space to the processing part 220C. The airflow processed by the processing unit 220C is delivered to the storage space.

In the solution of this embodiment, by setting the air circuit assembly 300C, and connecting the air flow processing channel 310C of the air circuit assembly 300C to the processing part 220C, and constructing the air intake section 312C and the air return section 314C in the air flow processing channel 310C, the air intake The section 312C transports the airflow from the storage space to the processing part 220C, and uses the air return section 314C to deliver the airflow processed by the processing part 220C to the storage space, so that an airflow circulation channel is formed between the storage space and the processing part 220C, which It is beneficial to improve the air circulation of the air conditioning process and optimize the air conditioning efficiency.

Since the air to be processed flows to the processing part 220C through the air intake section 312C, and the air after being processed returns to the storage space through the air return section 314C, the air intake section 312C and the air return section 314C are separated and set independently, "the air flow to be processed " and "processed airflow" will not significantly mix, which can reduce or prevent the treated airflow from being mixed into the airflow to be treated, thereby ensuring the efficiency of air conditioning.

In this embodiment, the gas flow processing channel is constructed by using the gas path component 300C, which can form an active circulation gas path between the storage space and the gas processing device 200C, and enhance the gas flow rate and flow order in the atmosphere control process.

Fig. 12 is a schematic structural view of a refrigerator 10C according to an embodiment of the present invention, and Fig. 13 is a partial enlarged view of A in Fig. 12 .

In some optional embodiments, the air circuit assembly 300C also has an air flow actuating device 320C, which is in air communication with the air flow processing channel 310C, and is used to promote the formation of air flow through the air intake section 312C, the processing part 220C, and the return air section 314C in sequence. and airflow in the storage space. Under the action of the airflow actuating device 320C, the flow rate of the airflow in the airflow circulation channel can be accelerated, so that the airflow to be treated in the storage space flows to the processing part 220C "successively", thereby improving the air conditioning efficiency.

The air flow actuating device 320C is disposed adjacent to the intake section 312C. For example, the air outlet of the airflow actuation device 320C can be connected to the air intake end of the air intake section 312C, and the air inlet of the airflow actuation device 320C can be connected to the air outlet 122C of the storage space, which is beneficial to improve the airflow actuation effect, thereby accelerating Air circulation rate.

In some embodiments, the airflow actuating device 320C may be an axial fan or a centrifugal fan, but is not limited thereto, as long as it can play a role in guiding the directional flow of the airflow.

When the storage space is the inner space of the storage container arranged in the storage compartment, the air outlet 122C and the air return port 124C can be opened in the storage space. on the wall of the container.

In some embodiments, the air inlet section 312C and the air return section 314C are vent pipes respectively, and the shapes of the air outlet 122C and the air return port 124C are adapted to the shapes of the air inlet section 312C and the air return section 314C, respectively, so as to achieve sealing engagement , to avoid air leakage. For example, the air inlet section 312C and the air return section 314C can be respectively inserted into the air outlet 122C and the air return port 124C in an interference fit manner, but the sealing engagement method is not limited thereto. On the basis of understanding the present embodiment, those skilled in the art should be able to easily expand and change the joining manner, and these expansions and changes should fall within the protection scope of the present invention.

The size of the preset threshold is set according to the size of the wall, for example, it may be 1/2 to 3/4 of the length of the wall.

With the above-mentioned structure, the airflow flowing through the air outlet 122C and the air return port 124C will not be significantly mixed, and the airflow flowing out of the air outlet 122C is almost all air to be treated, thereby providing sufficient raw materials for the processing part 220C and making the storage All the gases in the space can be processed "successively" relatively quickly.

In some optional embodiments, the specific gas component may be oxygen. The gas processing device 200C is an electrolysis device, and the processing part 220C is a cathode electrode 220C of the gas processing device 200C, which is used to consume oxygen in the storage space through an electrochemical reaction.

The specific gas components that the gas treatment device 200C can handle can be changed, and the gas treatment device 200C can also be changed to other devices, as long as it can play the role of atmosphere adjustment. For example, when the specific gas component is oxygen, the gas treatment device 200C can also be an oxygen-enriched membrane; when the specific gas component is an odor macromolecule, the gas treatment device 200C can be an adsorption device with an adsorbent.

The refrigerator 10C also has an oxygen transport channel 400C connecting the anode electrode 230C and the hyperoxic space 140C for transporting the oxygen generated by the anode electrode 230C to the hyperoxic space 140C. For example, the oxygen delivery channel 400C may be a vent tube.

That is to say, the oxygen generated by the anode electrode 230C can be transported to the hyperoxic space 140C through the oxygen delivery channel 400C, thereby The auxiliary high oxygen space 140C creates a high oxygen atmosphere. For example, a high-oxygen atmosphere is suitable for storing some meat ingredients and the like.

By connecting the anode electrode 230C of the gas treatment device 200C with the hyperoxic space 140C by using the oxygen transport channel 400C, and transporting the oxygen generated by the anode electrode 230C to the hyperoxic space 140C, the air-conditioning capability of the refrigerator 10C can be improved, and hypoxia can be created at the same time Fresh-keeping atmosphere and high-oxygen fresh-keeping atmosphere.

In some further embodiments, the gas treatment device 200C has an exhaust port 218C for exhausting oxygen generated by the anode electrode 230C. The oxygen delivery channel 400C has a first end 420C connected to the exhaust port 218C and a second end 440C connected to the nitrox space 140C. For example, the wall of the hyperoxic space 140C can be provided with an assembly port, and the second end 440C of the oxygen delivery channel 400C can be plugged into the assembly port through an interference fit to achieve a sealed joint and prevent air leakage, but the sealed joint does not Not limited to this.

In some optional embodiments, the diameter of the first end 420C of the oxygen delivery channel 400C is relatively small, and the diameter of the tube at the second end 440C is relatively large, so that the oxygen delivery channel 400C is in the shape of a gradually expanding diameter in the flow direction of the gas flow. , so set, the oxygen can spontaneously flow quickly along the flow direction of the airflow without any airflow actuating device.

The number of high oxygen spaces 140C can be set according to the actual space layout requirements of the refrigerator 10C. The number of oxygen delivery channels 400C and the number of hyperoxic spaces 140C may be the same, and the two are provided in a one-to-one correspondence. For example, when there is one hyperoxic space 140C, there is one oxygen delivery channel 400C, and the oxygen delivery channel 400C has a first end 420C and a second end 440C. When there are multiple hyperoxic spaces 140C, there are multiple oxygen delivery channels 400C, and each oxygen delivery channel 400C has a first end 420C and a second end 440C respectively.

In some embodiments, when there are multiple hyperoxic spaces 140C, the structure of the oxygen delivery channel 400C can also be changed. For example, there are multiple hyperoxic spaces 140C, and there are multiple second ends 440C, which are set in one-to-one correspondence with the hyperoxic spaces 140C, and each second end 440C is a branch extending from the first end 420C to the hyperoxic space 140C end of the tube as shown in Figure 14. That is to say, there is only one first end 420C of the oxygen delivery channel 400C connected to the exhaust port 218C. By adding branch pipes to the oxygen delivery channel 400C and making each branch pipe deliver oxygen to the corresponding hyperoxic space 140C, the It can simultaneously adjust the oxygen content of multiple high oxygen spaces 140C.

It should be noted that, as shown in FIG. 14 , the hypoxic space 120C can be converted into a high oxygen space 140C. For example, when the oxygen content of the space needs to be increased, the gas outlet 122C and the gas return port 124C of the space can be closed, and the oxygen It only needs to connect the second end 440C of the delivery channel 400C to the hypoxic space 120C. When it is necessary to reduce the oxygen content of the space, it is enough to open the air outlet 122C and the air return port 124C, and close the oxygen delivery channel 400C connecting the space, which can realize the functional reuse of a certain space.

In some alternative embodiments, the gas processing device 200C has a housing 210C having a gas flow chamber 214C and an electrolysis chamber 216C. The airflow chamber 214C communicates with the electrolysis chamber 216C through an opening, and the cathode electrode 220C is assembled to the opening to separate the airflow chamber 214C and the electrolysis chamber 216C. That is to say, the cathode electrode 220C isolates the gas flow chamber 214C from the electrolysis chamber 216C by closing the opening. The housing 210C may be roughly in the shape of a flat rectangular parallelepiped, and may be arranged upright, and the opening may be disposed in a longitudinal section plane of the housing 210C.

It should be noted that when there are multiple hypoxic spaces 120C, since each air circuit assembly 300C has an air inlet section 312C and an air return section 314C, accordingly, the air flow chamber 214C needs to have multiple sets of inlets 214Ca and outlets 214Cb Each set of inlets 214Ca and outlets 214Cb is respectively set corresponding to a hypoxic space 120C, and communicates with an air intake section 312C and a return air section 314C respectively connected to the corresponding hypoxic space 120C.

With the above-mentioned structure, the gas flow to be treated can be guided to the cathode electrode 220C in an orderly manner, and the oxygen in the gas flow can participate in the electrochemical reaction at the cathode electrode 220C, so that the oxygen is consumed, thereby forming a low-oxygen treatment gas flow. The airflow can be guided to the hypoxic space 120C in an orderly manner, and the whole airflow treatment process is more orderly, thereby improving the airflow treatment efficiency.

In the above embodiments, the connection manner between the gas processing device 200C and the storage space is illustrated by taking the case where the gas processing device 200C is arranged at the rear side of the storage space as an example. For example, the gas treatment device 200C may be disposed on the inner surface of the back plate of the box shell of the box body 100C. The air outlet 122C and the air return port 124C of the hypoxic space 120C can be arranged on the rear wall of the hypoxic space 120C, and the air inlet of the hyperoxic space 140C can be arranged on the rear wall of the hyperoxic space 140C.

FIG. 19 is a schematic block diagram of a refrigerator 1D according to one embodiment of the present invention. The refrigerator 1D in this embodiment should be understood in a broad sense, for example, it can be a refrigerator, a freezer, a storage cabinet and other storage equipment with a low-temperature preservation function.

The refrigerator 1D may generally include a cabinet 10D and an oxygen treatment device 200D.

A storage space 100D for storing objects and an installation space 101D outside the storage space 100D are formed inside the box body 10D.

The storage space 100D in this embodiment should be understood in a broad sense, as long as it has the function of storing the user's items to be kept fresh, it can be regarded as the storage space 100D. For example, the storage space 100D may refer to the internal space of the storage compartment, or the internal space of a storage container disposed in the storage compartment, or the peripheral environment space formed in the storage compartment and outside the storage container, or formed The accommodating space of the bottle seat on the door body, etc.

The installation space 101D may refer to other spaces except the storage space 100D, for example, it may be an inherent space provided by the refrigerator 1D for installing other components (such as compressors, air ducts, foaming materials, etc.).

The oxygen treatment device 200D is disposed in the installation space 101D, and has an electrode assembly configured to process oxygen in the storage space 100D through an electrochemical reaction, so as to increase or decrease the oxygen content in the storage space 100D. The electrode assembly may generally include an anode 230D and a cathode 220D for performing oxidation and reduction reactions, respectively.

In the refrigerator 1D of this embodiment, since a storage space 100D for storing items and an installation space 101D outside the storage space 100D are formed in the box body 10D, the installation space 101D may be an inherent space provided by the refrigerator 1D for installing other components. The oxygen treatment device 200D is arranged in the installation space 101D outside the storage space 100D, the oxygen treatment device 200D will not occupy any position in the storage space 100D, and the storage space 100D does not need to make room for the storage space, so the refrigerator 1D can be used without affecting Under the condition of low volume ratio, the controlled atmosphere preservation can be realized.

It should be emphasized that, for controlled atmosphere preservation, in order to facilitate the oxygen treatment device 200D to adjust the oxygen content of the storage space 100D, those of ordinary skill in the art can easily think of adopting the principle of proximity and setting the oxygen treatment device 200D in the storage space 100D, for example Setting it on the storage container or on the inner wall of the storage compartment will compress the volume ratio of the refrigerator 1D. The inventors of the present application creatively set an oxygen treatment device 200D in the installation space 101D outside the storage space 100D of the refrigerator 1D, and use the oxygen treatment device 200D to treat the oxygen in the storage space 100D, which breaks through the thinking of the prior art The shackles provide a new idea for the refrigerator 1D to achieve controlled atmosphere preservation while maintaining a high volume ratio, and also solve the problem that the oxygen treatment device 200D is easy to be touched by users. Multiple technical issues.

In some optional embodiments, the storage space 100D is a low temperature area inside the box body 10D. The installation space 101D is a high temperature area inside the box body 10D, and its temperature is higher than that of the storage space 100D. Wherein, "high temperature" and "low temperature" are relative terms, and the installation space 101D being a high temperature area does not mean that the temperature of the installation space 101D must be higher than a certain temperature.

Since the storage space 100D used for storage is a low-temperature area in the box body 10D, and the installation space 101D is a high-temperature area in the box body 10D, its temperature is higher than that of the storage space 100D, and the high-temperature environment can improve the electrochemical performance of the oxygen treatment device 200D. Therefore, the oxygen treatment device 200D of the refrigerator 1D can maintain a high air conditioning efficiency, and at the same time solve the problem of the risk of electrolyte freezing, which serves multiple purposes.

FIG. 20 is a schematic structural diagram of a refrigerator 1D according to an embodiment of the present invention.

In some optional embodiments, a compressor compartment 160D for installing a compressor is formed in the box body 10D. An installation space 101D is formed in the press chamber 160D. The press chamber 160D has a certain reserved space. Using the reserved space to form an installation space 101D and install the oxygen treatment device 200D can improve the space utilization rate of the refrigerator 1D. With the help of the temperature environment of the press chamber 160D, the oxygen treatment device 200D can exert high oxygen removal efficiency and oxygen production efficiency.

In some optional embodiments, at least a part of the oxygen treatment device 200D is shaped like an arc-shaped curved surface 218D, so as to be suitable for being installed in the press chamber 160D. The press chamber 160D generally has a spherical structure. At least a part of the oxygen treatment device 200D is configured as an arc-shaped curved surface 218D, and the arc-shaped curved surface 218D can be matched with the spherical structure of the press chamber 160D.

That is to say, on the basis of adjusting the installation position of the oxygen treatment device 200D, the solution of this embodiment further adjusts the shape of the oxygen treatment device 200D to match the reserved space of the press chamber 160D. In this way, the oxygen treatment device 200D can be smoothly placed in the installation space 101D in the compressor compartment 160D without improving the inherent compressor compartment 160D of the refrigerator 1D, which is conducive to improving the versatility of the oxygen treatment device 200D, and Reduced retrofit cost for Refrigerator 1D.

Compared with the flat structure in the prior art, the oxygen processing device 200D of this embodiment adds an arc-shaped curved surface 218D structure, which creatively provides a new type of oxygen processing device 200D with a unique shape and structure, which breaks through the flat structure of the refrigerator 1D. The ideological shackles of straight structure layout. The arc-shaped curved surface 218D structure can not only perfectly match the spherical structure of the press chamber 160D, but also increase the contact area between the oxygen treatment device 200D and the spherical body. In this way, the oxygen treatment device 200D can fully contact the electrode assembly with the gas to be treated with a small volume. The oxygen treatment device 200D has the advantages of high air conditioning efficiency and small size.

FIG. 21 is a schematic structural view of an oxygen treatment device 200D of a refrigerator 1D according to an embodiment of the present invention.

In some alternative embodiments, the oxygen treatment device 200D may include a housing 210D having an arcuate curved surface 218D. A gas-permeable area 218Da is opened on the arc-shaped curved surface 218D; the interior of the housing 210D defines an electrolytic chamber 216D located inside the gas-permeable area 218Da. The cathode 220D of the electrode assembly is an arc-shaped curved surface 218D plate adapted to the shape of the arc-shaped curved surface 218D, and is arranged at the air-permeable area 218Da. The anode 230D of the electrode assembly is of opposite polarity to the cathode 220D and is disposed at least partially within the electrolysis chamber 216D.

The ventilation area 218Da may be an opening or a through hole arranged in an array. The cathode 220D can be disposed inside the air-permeable area 218Da and cover the air-permeable area 218Da. The cathode 220D may have a waterproof and gas-permeable membrane. Alternatively, a waterproof and gas-permeable film is provided on the air-permeable area 218Da, and the cathode 220D is provided inside or outside of the waterproof and gas-permeable film.

For example, the shell 210D may be in the shape of a hollow sphere, and its shell wall forms an arc-shaped curved surface 218D. The air-permeable area 218Da is disposed on the hemispherical surface of the casing 210D. The anode 230D is opposite to the cathode 220D, and is disposed in the central section plane of the casing 210D.

As another example, the casing 210D may be in the shape of a hollow column, and its casing wall forms an arc-shaped curved surface 218D. The ventilation area 218Da is disposed on a half side of the casing 210D. The half side of the case 210D refers to half of the side of the cylindrical case 210D taken along the central longitudinal cut plane of the cylindrical case 210D. The cathode 220D is disposed at the air-permeable area 218Da, and the anode 230D may be disposed in the central longitudinal cut plane of the cylindrical housing 210D. For example, the plate surface of the anode 230D can be in the shape of a cuboid, whose width is equal to the diameter of the cylindrical housing 210D, and whose length is equal to the height of the cylindrical housing 210D, so that it is just arranged at the central longitudinal section of the housing 210D, thereby obtaining the maximum Board area.

FIG. 22 is a schematic structural diagram of a refrigerator 1D according to another embodiment of the present invention. Fig. 23 is a partial enlarged view of A in Fig. 22 .

In some optional embodiments, a foam layer 180D for heat insulation is also formed inside the box body 10D. It should be noted that the inside of the box 10D refers to the entire space located inside the outer peripheral wall of the refrigerator 1D. The foam layer 180D is located inside the box body 10D. The installation space 101D is formed in the foam layer 180D. The foam layer 180D can form a cavity through a molding process, and the shape of the cavity is adapted to the shape of the oxygen treatment device 200D, so that the oxygen treatment device 200D is suitable for being installed in the cavity.

The installation space 101D for installing the oxygen treatment device 200D is formed in the foam layer 180D by a molding process, which can omit subsequent processes such as drilling or opening holes, and can ensure process consistency, improve the processing accuracy of the cavity, and make the oxygen The processing device 200D is better assembled in the cavity to reduce damage rate.

The shape of the cavity can be set according to the shape of the oxygen treatment device 200D. In some optional embodiments, for example, when an When the storage space 101D is formed in the foam layer 180D, the oxygen treatment device 200D may be in a flat shape, such as a flat rectangular parallelepiped. The oxygen treatment device 200D of this shape may have a small thickness in a certain direction so as to be accommodated by the foamed layer 180D having a limited thickness.

In some optional embodiments, the box 10D includes an inner container. The inner side of the liner defines a storage space 100D. The installation space 101D is formed on the side of the inner tank facing away from the storage space 100D, that is, the rear side of the inner tank, which can shorten the distance between the oxygen treatment device 200D and the storage space, simplify the structure of the gas circuit components, and reduce the manufacturing cost.

For example, the housing 210D of the oxygen treatment device 200D may be approximately flat and rectangular. And the casing 210D is provided with a side opening. The cathode 220D is disposed at the side opening to define together with the housing 210D an electrolytic cavity 216D for containing the electrolyte. The anode 230D can be disposed in the electrolysis chamber 216D.

In some optional embodiments, the refrigerator 1D may further include an active circulation air path, connected between the storage space 100D and the oxygen treatment device 200D, configured to promote the flow from the storage space 100D to the oxygen treatment device 200D, and then The airflow returning to the storage space 100D circulates. In this embodiment, the storage space 100D may refer to the hypoxic storage space 120D. The hypoxic storage space 120D may have a gas outlet 122D and a gas return port 124D for discharging gas and receiving gas, respectively.

Since the storage space 100D and the oxygen treatment device 200D are connected with an active circulation gas path, under the action of the active circulation gas path, an air circulation channel can be formed between the storage space 100D and the oxygen treatment device 200D, which is beneficial to improve the process of air conditioning Excellent air circulation, improve the air circulation of the air conditioning process, and further optimize the air conditioning efficiency.

Under the action of the active circulation gas path, the gas to be treated in the storage space 100D can smoothly flow to the oxygen treatment device 200D, and make the oxygen in the gas to be treated participate in the electrochemical reaction of the cathode 220D as a reactant, thereby reducing the gas concentration in the gas. low oxygen content, these hypoxic gases can be returned to the storage space 100D, and after one or more airflow cycles, the storage space 100D can form a hypoxic fresh-keeping atmosphere.

With the above-mentioned structure, the gas flow to be treated can be guided to the cathode 220D in an orderly manner, and the oxygen in the gas flow can participate in the electrochemical reaction at the cathode 220D, so that the oxygen is consumed, thereby forming a low-oxygen treatment gas flow, which in turn It can be guided to the storage space 100D in an orderly manner, and the entire airflow processing process is more orderly, thereby improving the airflow processing efficiency.

In some optional embodiments, the oxygen treatment device 200D further includes a treatment air duct 214Dc, which is in airflow communication with the active circulation air path, and is used to make the gas from the storage space 100D flow through the cathode 220D. That is to say, the processing air passage 214Dc in this embodiment acts as a guide, and the gas from the storage space 100D flows through the cathode 220D under the guidance of the processing air passage 214Dc.

In the refrigerator 1D of this embodiment, because the processing air channel 214Dc can make the gas from the storage space 100D flow through the cathode 220D, so that the cathode 220D can process the oxygen in the gas, when it is necessary to adjust the gas environment of the storage space 100D, only It is only necessary to connect the active circulation gas path with the processing channel, and it is not necessary to install the entire oxygen treatment device 200D at the gas-permeable area 218Da of the storage space 100D, and the oxygen treatment device 200D can be installed in other positions away from the storage space 100D.

The flow path of the gas to be treated in the oxygen treatment device 200D forms a treatment air channel 214Dc. Because the processing air channel 214Dc can make the gas from the storage space 100D flow through the cathode 220D, the processing air channel 214Dc can make the gas fully contact with the cathode 220D during the process of guiding the gas. Based on the guiding effect of the processing air channel 214Dc, the refrigerator 1D Higher air conditioning efficiency can be obtained.

In some optional embodiments, the active circulation air circuit includes an air intake pipe 310D and a return air pipe 320D.

Wherein, the air intake pipe 310D communicates with the air intake end of the processing air duct 214Dc and the storage space 100D, and is configured to deliver the airflow from the storage space 100D to the processing air duct 214Dc. The air return pipe 320D communicates with the air outlet end of the processing air channel 214Dc and the storage space 100D, and is configured to transport the airflow treated by the cathode 220D to the storage space 100D. Wherein, the air outlet 122D of the hypoxic storage space 120D can communicate with the air intake pipe 310D, and the air return port 124D communicates with the air return pipe 320D.

Since the gas to be processed flows to the processing air duct 214Dc through the air inlet pipe 310D, and the treated gas returns to the storage space 100D through the air return pipe 320D, the air inlet pipe 310D and the air return pipe 320D are separated and set independently, "to be processed Airflow" and "processed airflow" will not significantly mix, which can reduce or prevent the treated airflow from being mixed into the airflow to be treated, thereby ensuring the efficiency of air conditioning.

In some further embodiments, an airflow actuating device 330D is arranged on the active circulation air path, which is arranged on the airflow path of the intake pipe 310D and is configured to promote the formation of airflow circulation. Under the action of the airflow actuating device 330D, the flow rate of the airflow in the airflow circulation channel can be accelerated, so that the airflow to be treated in the storage space 100D flows to the processing air duct 214Dc "successively", thereby improving the air conditioning efficiency. For example, the airflow actuating device 330D may be connected to the airflow inlet of the intake pipe 310D.

For example, the air outlet end of the airflow actuation device 330D can be connected to the air intake end of the air intake pipe 310D, and the air inlet end of the airflow actuation device 330D can be connected to the hypoxic storage space 120D, which is beneficial to improve the airflow actuation effect, thereby accelerating Air circulation rate.

In some embodiments, the airflow actuating device 330D may be an axial fan or a centrifugal fan, but is not limited thereto, as long as it can guide the directional flow of the airflow.

In some alternative embodiments, the housing 210D of the oxygen treatment device 200D may have a gas flow chamber 214D and an electrolysis chamber. The airflow chamber 214D communicates with the electrolysis chamber through an opening, and the cathode 220D is assembled to the opening to separate the airflow chamber 214D from the electrolysis chamber. that is That is, the cathode 220D isolates the gas flow chamber 214D from the electrolysis chamber by closing the opening. The opening may be provided in a longitudinal cut plane of the housing 210D. The area of the opening may be smaller than or equal to the cross-sectional area of the longitudinal cut plane.

In this embodiment, the airflow chamber 214D and the electrolysis chamber can be integrated, for example, can be integrally formed through a molding process, which can simplify the processing technology of the housing 210D. In some optional embodiments, the air flow chamber 214D and the electrolysis chamber may not be integrated. For example, the electrolysis chamber may be roughly in the shape of a flat cuboid, and its wider side has an installation opening, and the cathode 220D is assembled to the installation opening to close the electrolysis chamber. The airflow chamber 214D may be roughly in the shape of a flat rectangular parallelepiped with side openings, and covers the wider sides of the electrolysis chamber.

The interior of the electrolysis chamber forms an electrolysis chamber 216D. The interior of the airflow chamber 214D may form a processing air duct 214Dc. The air flow chamber 214D is provided with an inlet 214Da and an outlet 214Db, wherein the inlet 214Da communicates with the air intake pipe 310D, and the outlet 214Db communicates with the return air pipe 320D.

Of course, the above examples of the shape of the oxygen treatment device 200D are exemplary, and the shape of the oxygen treatment device 200D is not limited thereto. In some other embodiments, the oxygen treatment device 200D can be transformed into other shapes according to actual needs, such as a polyhedron shape.

FIG. 24 is a schematic structural view of an oxygen treatment device 200D of a refrigerator 1D according to another embodiment of the present invention.

In some optional embodiments, the cathode 220D and the anode 230D respectively include multi-segment electrode plates, and respectively jointly enclose a hollow cylinder, such as a hollow cylinder, or a hollow prism. Wherein, the hollow prism may be a triangular prism, a quadrangular prism, a pentagonal prism, or a hexagonal prism, and is preferably a quadrangular prism.

The hollow cylinder where the cathode 220D is located is nested inside the hollow cylinder where the anode 230D is located. An electrolysis chamber 216D is formed between the cathode 220D and the anode 230D. The side of the cathode 220D facing away from the anode 230D forms a processing air channel 214Dc which is in airflow communication with the storage space 100D, so that the oxygen in the gas flowing through the processing air channel 214Dc contacts the cathode 220D.

In this embodiment, the processing air duct 214Dc has a definite air inlet end and an air outlet end, and extends from the air inlet end to the air outlet end. The gas to be treated can flow along the extending direction of the processing air duct 214Dc. During the flow, the oxygen in the gas continuously participates in the electrochemical reaction and is consumed, which can make the gas flowing out of the processing air duct 214Dc contain very little Oxygen, which is conducive to strengthening the effect of air conditioning, reducing the time required for air conditioning, and reducing the number of airflow cycles. Only one or a small number of airflow cycles between the storage space 100D and the oxygen treatment device 200D may be needed to meet the oxygen reduction requirement of the first storage space 100D.

In some optional embodiments, the oxygen treatment device 200D further includes a first protective frame 250D and a second protective frame 260D. Wherein, the first protective frame 250D is in the shape of a hollow cylinder, and is sheathed outside the hollow cylinder where the anode 230D is located. The second protective frame 260D is also in the shape of a hollow column, and is sheathed inside or outside of the hollow column where the cathode 220D is located. And the first protective frame 250D and the second protective frame 260D close the gap between the anode 230D and the cathode 220D.

The anode 230D and the cathode 220D are respectively protected by the first protective frame 250D and the second protective frame 260D, which can improve the structural strength of the oxygen treatment device 200D to a certain extent, and reduce or avoid electrolyte leakage.

For the electrochemical reaction between the cathode 220D and the anode 230D, for example, oxygen in the air can undergo a reduction reaction at the cathode 220D, namely: O ₂ +2H ₂ O+4e ⁻ →4OH ⁻ . The OH ⁻ produced by the cathode 220D can undergo an oxidation reaction at the anode 230D to generate oxygen, namely: 4OH ⁻ →O ₂ +2H ₂ O+4e ⁻ . The anode 230D provides reactants, such ^as electrons e − , to the cathode 220D while utilizing OH ⁻ to undergo an electrochemical reaction. The anode 230D also generates oxygen gas during the electrochemical reaction.

In this embodiment, the storage space 100D may include a hypoxic storage space 120D and a high oxygen storage space 140D. Since the anode 230D generates oxygen during the electrochemical reaction, this part of oxygen can be utilized, for example, it can be transported to the high oxygen storage space 140D of the refrigerator 1D, which can improve the air conditioning capability of the refrigerator 1D, making it simultaneously create a low-oxygen fresh-keeping atmosphere and high-oxygen fresh-keeping atmosphere. For example, an oxygen delivery pipeline may be communicated between the electrolysis chamber 216D and the high oxygen storage space 140D. The oxygen treatment device 200D may have an exhaust port 21D for exhausting the separated oxygen. The first end 420D of the oxygen delivery pipeline 400 can communicate with the exhaust port 21D of the oxygen treatment device 200D, and the second end 440D can communicate with the high oxygen storage space 140D, so as to guide the oxygen discharged from the exhaust port 21D to high Oxygen storage space 140D.

FIG. 25 is a schematic structural diagram of a refrigerator 10E according to an embodiment of the present invention. The refrigerator 10E of this embodiment should be understood in a broad sense, for example, it can be a refrigerator, a freezer, a storage cabinet and other storage equipment with a low-temperature preservation function.

The refrigerator 10E may generally include a box body 100E, a gas treatment device 200E, and a liquid quality adjustment box 510E. The housing 100E is omitted in FIG. 25 .

A storage space 120E is formed inside the box body 100E. The storage space 120E in this embodiment should be understood broadly. For example, the storage space 120E may refer to an inner space of a storage compartment, or an inner space of a storage container disposed in the storage compartment, or a peripheral environmental space formed in the storage compartment and located outside the storage container.

The gas treatment device 200E has an electrolysis chamber 240E and an electrode assembly. The electrolysis chamber 240E is configured to hold an electrolyte solution. The electrode assembly is configured to be immersed in the electrolyte solution contained in the electrolysis chamber 240E, and the specific gas components in the storage space 120E are processed through an electrochemical reaction. deal with. The specific gas component may be oxygen, or nitrogen, carbon dioxide, etc., which is not limited in this embodiment. The specific gas component in the storage space 120E is processed through an electrochemical reaction to increase or decrease the content of the specific gas component.

The liquid quality regulating tank 510E is configured to store the electrolyte to replenish the electrolytic chamber 240E so as to adjust the liquid quality of the electrolyte in the electrolytic chamber 240E. The liquid quality of the electrolyte refers to the quality of the electrolyte, that is, the liquid volume and concentration of the electrolyte. The electrolyte solution stored in the liquid quality adjustment tank 510E may be consistent with the electrolyte solution contained in the electrolysis chamber 240E.

The refrigerator 10E of this embodiment is provided with a liquid quality adjustment tank 510E, when using the electrolyte stored in the liquid quality adjustment tank 510E to replenish the electrolysis chamber 240E of the gas processing device 200E, water can be replenished to the electrolysis chamber 240E , and can replenish the electrolyte to the electrolytic chamber 240E, therefore, it can fully compensate for the loss of the electrolyte, better adjust the liquid quality of the electrolyte in the electrolytic chamber 240E, improve the effect of liquid replacement, and make the "quantity" and "quality" of the electrolyte Recover as much as possible and maintain the original state.

Use the electrolyte stored in the liquid quality adjustment tank 510E to replenish the electrolytic chamber 240E, so that the lost substances in the electrolyte can be replenished in time. Compared with the scheme of simply replenishing water to the electrolytic chamber 240E, the refrigerator 10E and the gas treatment device 200E of this scheme The concentration of the electrolyte solution does not decrease significantly within a certain period of time, so the gas treatment device 200E can maintain good gas-conditioning efficiency for a long time.

Since the liquid quality adjustment tank 510E can store electrolyte in advance, when it is necessary to replenish the electrolytic chamber 240E, it is only necessary to connect the liquid path between the liquid quality adjustment tank 510E and the electrolytic chamber 240E, and the user does not need to contact the electrolytic chamber during the liquid replacement process. fluid, which is conducive to improving the safety of the fluid rehydration process.

Since the liquid quality adjustment tank 510E is used to replenish the electrolytic chamber 240E, the electrolyte of the gas treatment device 200E can be maintained in its initial state. Therefore, there is no need to over-consider the electrolyte loss problem, and it is not necessary to pre-install the electrolyte in the electrolytic chamber 240E. The electrolyte solution with a higher concentration is beneficial to reduce the packaging difficulty of the gas processing device 200E and reduce the manufacturing cost. The electrolyte chamber 240E only needs to be pre-installed with an electrolyte with a suitable concentration, and the packaging shell of the gas processing device 200E does not need to use materials with high corrosion resistance.

It should be emphasized that in the face of the electrolyte loss problem, the remedial measures adopted in the prior art are replenishing water without adjusting the liquid quality of the electrolyte. However, the inventor realized that "hydration" cannot make up for the loss of electrolyte, and the "quality" of the electrolyte cannot be well restored. Moreover, due to factors such as the high volume ratio of the refrigerator 10E and the need to ensure the safety of the storage environment, even if it is necessary to replenish the electrolytic chamber 240E, those skilled in the art would never think of storing corrosive liquids in the refrigerator 10E (e.g. electrolyte). Therefore, the inventors of the present application creatively set the liquid quality adjustment box 510E on the refrigerator 10E to adjust the liquid quality of the electrolyte in the electrolysis chamber 240E, which breaks through the shackles of the prior art and solves the problem of electrolysis of the gas treatment device 200E. The problem of liquid loss provides a new idea, and at the same time solves many technical problems such as the high packaging difficulty of the gas processing device 200E, which serves multiple purposes.

In some optional embodiments, the refrigerator 10E may further include a transfusion tube 530E. The infusion tube 530E is connected between the electrolysis chamber 240E and the liquid quality adjustment tank 510E, and is configured to transport the electrolyte contained in the liquid quality adjustment tank 510E to the electrolysis chamber 240E. The liquid quality adjustment tank 510E and the electrolysis chamber 240E are connected through the infusion tube 530E. The distance between the liquid quality adjustment tank 510E and the gas processing device 200E is adjustable, and can be set at any position away from or close to the gas processing device 200E.

In some further embodiments, the refrigerator 10E may further include a power component 520E. The power unit 520E is disposed on the infusion tube 530E, configured to be activated under control, so as to promote the electrolyte to flow from the liquid quality adjustment tank 510E to the electrolysis chamber 240E. That is to say, the power component 520E is used to provide power for liquid flow. Under the action of the power component 520E, the electrolyte in the liquid quality adjustment tank 510E flows through the infusion tube 530E and then flows to the electrolysis chamber 240E.

By installing the infusion tube 530E and the power unit 520E, the installation location of the liquid quality adjustment tank 510E can be very flexible, and is not limited to the installation location of the gas processing device 200E. The liquid quality adjustment tank 510E can be set anywhere away from the storage space 120E, such as in the air duct, in the foam material or in the press chamber, and can also be set outside the tank 100E, such as the top of the tank 100E. When the liquid quality adjustment box 510E is set at the above position, it is not easy to be touched by the user, and it will not occupy the storage space 120E of the refrigerator 10E, which can not only ensure the safety, but also ensure the volume ratio.

In some optional embodiments, the refrigerator 10E may further include a liquid return pipe 540E, which is connected between the liquid quality adjustment tank 510E and the electrolysis chamber 240E, and is set independently from the liquid infusion pipe 530E, and is configured to be connected to the power unit 520E When starting, the electrolyte flows from the electrolysis chamber 240E to the liquid quality adjustment tank 510E to form an electrolyte circulation flow path. That is, there are two pipes connected between the liquid quality adjustment tank 510E and the electrolysis chamber 240E, one is the infusion pipe 530E, and the other is the liquid return pipe 540E, and the electrolyte in the liquid quality adjustment tank 510E flows into the electrolysis chamber from the infusion pipe 530E 240E, the electrolyte in the electrolysis chamber 240E flows into the liquid quality adjustment tank 510E from the liquid return pipe 540E. That is, the liquid quality adjustment tank 510E, the infusion tube 530E, the electrolysis chamber 240E, the liquid return tube 540E and the liquid quality adjustment tank 510E are connected in sequence to form an electrolyte circulation flow path.

By installing the liquid return pipe 540E, the infusion pipe 530E and the power unit 520E, when the liquid quality adjustment tank 510E is used to supplement the electrolysis chamber 240E, if the electrolysis chamber 240E is filled with electrolyte, the excess electrolyte will flow through the liquid return pipe 540E. Back to the liquid quality adjustment tank 510E, and will not cause overflow or leakage. Therefore, the refrigerator 10E of this embodiment does not need to install a liquid level sensor in the electrolytic chamber 240E to detect whether the electrolytic chamber 240E is filled with electrolyte, nor does it need to control the liquid replenishment process according to the detection result of the liquid level sensor, which not only simplifies the hardware structure, and simplifies the control logic.

For example, based on the structure of this embodiment, when replenishing fluid, the working time of the power component 520E is preset, and the starting time of the power component 520E is counted to determine when to stop the fluid replenishment.

It should be further explained that, during the process of rehydration, when determining when to end the rehydration, those skilled in the art will automatically Under the constraints of such thinking, it is easy to think of using a liquid level sensor to detect the liquid level. However, since the electrolyte is corrosive, the cost of installing a corrosion-resistant liquid level sensor in the electrolytic chamber 240E is very high. Based on the solution of this embodiment, the refrigerator 10E does not need to accurately determine when to end the liquid replenishment, not only skillfully avoids the installation of a liquid level sensor, but also solves the risk of overflow and leakage, and has a good application prospect.

In some optional embodiments, the power component 520E is a pump, such as a micro water pump, but not limited thereto. The power component 520E is configured to cut off the infusion tube 530E in the closed state. That is, the power unit 520E allows the electrolyte to flow from the liquid quality regulating tank 510E into the infusion tube 530E and into the electrolysis chamber 240E only after the controlled activation.

Fig. 26 is a schematic structural diagram of a refrigerator 10E according to another embodiment of the present invention, in which the cabinet 100E is omitted. In some optional embodiments, the refrigerator 10E may further include a water tank 710E, a water delivery pipe 720E and a switch element 730E.

Wherein, the water tank 710E is configured to contain water to replenish water to the liquid quality adjustment tank 510E. The water delivery pipe 720E is connected between the water tank 710E and the liquid quality adjustment tank 510E, and is configured to deliver the water contained in the water tank 710E to the liquid quality adjustment tank 510E. The switch element 730E is disposed on the water delivery pipe 720E, configured to be opened and closed in a controlled manner to switch the water delivery pipe 720E. The switch element 730E can be a solenoid valve or a manual switch valve or the like.

The inventors further realized that during the electrolyte loss process in the electrolytic chamber 240E, the water loss rate is greater than the electrolyte loss rate. As the use time continues to prolong, the electrolyte concentration in the electrolysis chamber 240E and the liquid quality adjustment tank 510E will increase. At this time, the switch element 730E is activated, and the water delivery pipe 720E is connected to the water tank 710E and the liquid quality adjustment tank 510E. And properly adjust the concentration of the electrolyte in the liquid quality adjustment tank 510E, thereby indirectly adjusting the concentration of the electrolyte in the electrolytic chamber 240E to restore it to the initial level.

In some optional embodiments, a flow sensor 740E may be provided in the water delivery pipe 720E for detecting the flow of the liquid.

There are one or more storage spaces 120E. In some optional embodiments, there may be multiple storage spaces 120E. The electrode assembly includes a plurality of first electrode plates 210E with different orientations, so that each first electrode plate 210E is respectively provided with a storage space 120E in airflow communication therewith. The orientations of the plurality of first electrode plates 210E are set to be different, so as to communicate with the storage spaces 120E at different orientations, so as to adjust the specific gas composition of the storage spaces 120E.

Different orientations of the first electrode plates 210E mean that the first electrode plates 210E are not in the same plane. For example, adjacent first electrode plates 210E may form a certain angle or arc, which facilitates multiple first electrode plates 210E to face different storage spaces 120E at the same time, and communicate with different storage spaces 120E at the same time. Therefore, only one gas processing device 200E is required to adjust the atmosphere of multiple storage spaces 120E at the same time. The refrigerator 10E of this embodiment can realize the multiple functions of the gas processing device 200E, which is beneficial to simplify the structure of the refrigerator 10E and improve the Freshness preservation performance.

The electrode assembly also includes a plurality of second electrode plates 220E, which are respectively arranged one by one opposite to the first electrode plates 210E, so as to form multiple sets of electrode pairs.

In some optional embodiments, the polarities of the multiple first electrode plates 210E can be the same, and the polarities of the multiple second electrode plates 220E can be the same, which is beneficial to ensure the consistency of the first electrode plates 210E and the second electrode plates 210E. The consistency of the electrode plate 220E reduces or avoids confusion. In each electrode pair, the polarity of the first electrode plate 210E and the second electrode plate 220E are opposite, and may be either an anode or a cathode, respectively.

By arranging a plurality of first electrode plates 210E, and making the plurality of first electrode plates 210E and the plurality of second electrode plates 220E one-to-one to form a plurality of electrode pairs, each group of electrode pairs can independently perform electrochemical reactions , so as to independently adjust the gas composition corresponding to the storage space 120E, which can make the gas processing device 200E adapt to the different atmosphere adjustment requirements of multiple storage spaces 120E, which is beneficial to improve the versatility of the gas processing device 200E.

Of course, in other optional embodiments, the polarities of the plurality of first electrode plates 210E may not be completely the same, and the polarities of the plurality of second electrode plates 220E may not be completely the same, as long as it is ensured that the first electrode of each group of electrode pairs The polarity of the first electrode plate 210E is opposite to that of the second electrode plate 220E. In this case, the polarity of the electrode plate in airflow communication with the storage space 120E can be set according to the actual air conditioning requirements of the storage space 120E.

The electrolysis chamber 240E can contain an alkaline electrolyte, such as 0.1-8 mol/L NaOH or KOH, and its concentration can be adjusted according to actual needs.

In some optional embodiments, the first electrode plate 210E may be a cathode configured to reduce the oxygen content of the storage space 120E through an electrochemical reaction. The second electrode plate 220E may be an anode configured to provide a reactant to the corresponding first electrode plate 210E through an electrochemical reaction.

The specific gas component in this embodiment refers to oxygen. For example, oxygen in the air can undergo a reduction reaction at the cathode, namely: O ₂ +2H ₂ O+4e ^- →4OH ^- . The OH ^- produced by the cathode can undergo oxidation reaction at the anode and generate oxygen, namely: 4OH ^- → O ₂ +2H ₂ O + 4e ^- . The anode provides reactants, such as electrons e ^- , to the cathode while utilizing OH ^- for electrochemical reaction.

That is, the second electrode plate 220E is also configured to generate oxygen gas when an electrochemical reaction is performed. In some embodiments, the gas treatment device 200E also has an exhaust part configured to discharge the oxygen generated by the second electrode plate 220E into the box 100E. For example, the storage space 120E may include a high oxygen storage space 120E, and the exhaust part An oxygen delivery pipeline 400 may be communicated with the high oxygen storage space 120E for delivering oxygen.

Of course, the above examples of electrochemical reactions and their equations are only illustrative. On the basis of understanding these embodiments, those skilled in the art should easily apply the refrigerator 10E of this embodiment to other types of electrochemical reactions, And address other types of specific gas components, such as electrochemical reactions for the production or consumption of carbon dioxide, electrochemical reactions for the production or consumption of nitrogen, electrochemical reactions for the production or consumption of ethylene, etc., these extensions should Fall into the protection scope of the present invention.

With the above structure, the gas processing device 200E can process the oxygen in the storage space 120E of the refrigerator 10E, so as to conform to the development concept of low-oxygen preservation, prolong the shelf life of fruits and vegetables and other food materials, and improve the freshness preservation performance of the refrigerator 10E. At the same time, because the anode generates oxygen during the electrochemical reaction, this part of the oxygen can be utilized, for example, it can be transported to the high oxygen space of the refrigerator 10E, which can improve the air conditioning ability of the refrigerator 10E, so that it can simultaneously create a low-oxygen fresh-keeping atmosphere and High oxygen freshness preservation atmosphere.

FIG. 27 is a schematic structural diagram of a gas treatment device 200E of a refrigerator 10E according to an embodiment of the present invention. In some optional embodiments, the plurality of first electrode plates 210E and the plurality of second electrode plates 220E respectively surround a hollow quadrangular prism. Moreover, the hollow quadrangular prism where the first electrode plate 210E is located is sheathed outside the hollow quadrangular prism where the second electrode plate 220E is located.

Since a plurality of first electrode plates 210E and a plurality of second electrode plates 220E respectively form a hollow quadrangular prism, and the hollow quadrangular prism where the first electrode plate 210E is located is sleeved outside the hollow quadrangular prism where the second electrode plate 220E is located. Therefore, the first electrode plates 210E face each other in pairs. When the gas processing device 200E is arranged between two storage spaces 120E arranged side by side, each storage space 120E can be opposite to a first electrode plate 210E respectively. The unique structure of the device 200E can perfectly match the layout structure of the storage space 120E of the refrigerator 10E, and the structure is ingenious, which is beneficial to reduce the structure of the gas path and optimize the spatial layout of the refrigerator 10E.

For example, in some optional embodiments, the storage space 120E may include a first fresh-keeping space and a second fresh-keeping space juxtaposed along the lateral direction. The hollow quadrangular prism where the first electrode plate 210E is located is set between the first fresh-keeping space and the second fresh-keeping space, and a first electrode plate 210E is respectively set on the lateral sides of the hollow quadrangular prism, so as to communicate with the first fresh-keeping space respectively. The fresh-keeping space is in airflow communication with the second fresh-keeping space, so as to adjust the oxygen content of the first fresh-keeping space and the second fresh-keeping space respectively.

Of course, the spatial layout of the refrigerator 10E is not limited to this. For example, in other optional embodiments, the first fresh-keeping space and the second fresh-keeping space are juxtaposed up and down. The hollow quadrangular prism where the first electrode plate 210E is located is set between the first fresh-keeping space and the second fresh-keeping space, and a first electrode plate 210E is respectively set on the upper and lower sides of the hollow quadrangular prism, so as to communicate with the first fresh-keeping space respectively. The fresh-keeping space is in airflow communication with the second fresh-keeping space.

The gap between the first electrode plate 210E and the second electrode plate 220E forms an electrolytic cavity 240E for containing electrolyte. In some optional embodiments, the gas treatment device 200E further includes a first protective frame 261E and a second protective frame 262E. Wherein, the first protective frame 261E is in the shape of a hollow quadrangular prism, and is sheathed outside the hollow prism where the first electrode plate 210E is located. The second protective frame 262E is also in the shape of a hollow prism, and is sheathed inside or outside of the hollow prism where the second electrode plate 220E is located. And the first protective frame 261E and the second protective frame 262E close the gap between the first electrode plate 210E and the second electrode plate 220E.

The first electrode plate 210E and the second electrode plate 220E are respectively protected by the first protective frame 261E and the second protective frame 262E, which can improve the structural strength of the gas treatment device 200E to a certain extent and reduce or avoid electrolyte leakage. In some further embodiments, the first protective frame 261E may be provided with ventilation holes for allowing gas to pass through, so as to avoid completely covering the first electrode plate 210E and ensure the normal operation of the modified atmosphere process.

In some optional embodiments, the first fresh-keeping space and the second fresh-keeping space may be storage drawers respectively, and a ventilating area is opened on the wall of the drawer to communicate with the corresponding first electrode plate 210E. For example, the first electrode plate 210E may cover the side of the air-permeable area facing away from the inner space of the drawer, so as to shield the air-permeable area. The air-permeable area can be formed by perforating or opening.

It should be noted that although the plurality of first electrode plates 210E and the plurality of second electrode plates 220E respectively form a hollow quadrangular prism, it does not mean that each surface of the hollow quadrangular prism where the first electrode plate 210E is located The fact that the first electrode plate 210E is always arranged does not mean that the second electrode plate 220E is arranged on every surface of the hollow quadrangular prism where the second electrode plate 220E is located.

Fig. 28 is a schematic structural view of a refrigerator 10E according to an embodiment of the present invention, and Fig. 29 is a partial enlarged view of A in Fig. 28 .

In some optional embodiments, the hollow quadrangular prism where the first electrode plate 210E is located is nested inside the hollow cylinder where the second electrode plate 220E is located. Moreover, the side of the hollow quadrangular prism where the first electrode plate 210E is located faces away from the second electrode plate 220E forms a processing air channel 230E.

At this moment, the processing air channel 230E has a definite air inlet end 231E and an air outlet end 232E, and extends from the air inlet end 231E to the air outlet end 232E. The gas to be treated can flow along the extending direction of the processing air duct 230E. During the flow, the oxygen in the gas continuously participates in the electrochemical reaction and is consumed, which can make the gas flowing out of the processing air duct 230E contain very little Oxygen, which is conducive to strengthening the effect of air conditioning, reducing the time required for air conditioning, and reducing the number of airflow cycles. Only one or a small number of airflow cycles between the storage space 120E of the refrigerator 10E and the gas processing device 200E may be needed to meet the oxygen reduction requirement of the storage space 120E.

When the hollow quadrangular prism where the first electrode plate 210E is located is nested outside the hollow cylinder where the second electrode plate 220E is located, the gas treatment device 200E may also have a hollow columnar housing 250E, which is packaged in the hollow column where the first electrode plate 210E is located. The outer side of the hollow quadrangular prism, and the gap between the hollow quadrangular prism where the first electrode plate 210E is located encloses the processing air duct 230E. An air inlet and an air outlet are respectively provided on the hollow cylindrical shell 250E, serving as the air inlet 231E and the air outlet 232E respectively. The air inlet and the air outlet of this embodiment are mutually Set away from it to extend the gas path of the process air duct 230E.

In some optional embodiments, the refrigerator 10E may further include an air intake component 310E and a return air component 320E. Wherein, the air intake component 310E communicates with the air intake end 231E of the processing air duct 230E and the storage space 120E, and is configured to transport the airflow from the storage space 120E to the processing air duct 230E.
