Detailed Description

Fig. 1 is a schematic block diagram of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 may generally include a cabinet 100, a gas processing device 200, and a gas path assembly 300.

In which a storage space is defined inside the case 100 for storing articles such as food materials, medicines, etc. The storage space may refer to an interior space of a storage compartment (e.g., a refrigerator compartment, a freezer compartment, etc.), or may refer to an interior space of a storage container (e.g., a storage drawer, a basket, etc.) disposed within the storage space.

The gas processing device 200 is disposed in the box 100 and has a processing portion 220, and the processing portion 220 is in gas flow communication with the storage space and is used for processing a specific gas component of the storage space, for example, reducing the content of the specific gas component or increasing the content of the specific gas component.

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

The gas flow treatment channel 310 has an air inlet section 312 and an air return section 314. The air inlet section 312 is connected between the storage space and the processing portion 220 and is used for conveying the airflow from the storage space to the processing portion 220, and the air return section 314 is connected between the processing portion 220 and the storage space and is used for conveying the airflow processed by the processing portion 220 to the storage space.

In the solution of this embodiment, by providing the air path assembly 300, communicating the air flow processing channel 310 of the air path assembly 300 with the processing portion 220, constructing the air inlet section 312 and the air return section 314 in the air flow processing channel 310, using the air inlet section 312 to convey the air flow from the storage space to the processing portion 220, and using the air return section 314 to convey the air flow processed by the processing portion 220 to the storage space, an air flow circulation channel can be formed between the storage space and the processing portion 220, which is beneficial to improving the air flow circulation performance in the air conditioning process and optimizing the air conditioning efficiency.

Since the air to be treated flows to the treatment part 220 through the air inlet section 312, and the treated air flows return to the storage space through the air return section 314, the air inlet section 312 and the air return section 314 are separately and independently arranged, and no obvious mixed flow occurs between the "air to be treated" and the "air after being treated", which can reduce or prevent the air after being treated from mixing into the air to be treated, thereby ensuring the air conditioning efficiency.

In this embodiment, the air path assembly 300 is used to construct the air flow processing channel, so that an active circulation air path can be formed between the storage space and the air processing device 200, thereby enhancing the air flow rate and flow order in the air conditioning process.

Fig. 2 is a schematic structural view of a refrigerator 10 according to an embodiment of the present invention, and fig. 3 is a partial enlarged view of a portion a in fig. 2.

In some alternative embodiments, the air path assembly 300 further has an air flow actuating device 320 in air path communication with the air flow processing channel 310 for promoting the formation of an air flow sequentially passing through the air inlet section 312, the processing portion 220, the air return section 314 and the storage space. Under the action of the airflow actuating device 320, the airflow flowing speed in the airflow circulation channel can be increased, so that the airflow to be processed in the storage space can flow to the processing portion 220 in a "successive" manner, and the air conditioning efficiency is improved.

The airflow actuation device 320 is disposed proximate to the air intake section 312. For example, the air outlet of the airflow actuator 320 may be connected to the air inlet end of the air inlet section 312, and the air inlet of the airflow actuator 320 may be connected to the air outlet 122 of the storage space, which is beneficial to increase the airflow actuation effect, thereby accelerating the airflow circulation rate.

In some embodiments, the airflow actuator 320 may be an axial fan or a centrifugal fan, but is not limited thereto, as long as it can function to direct the airflow in a directional flow.

In some alternative embodiments, the gas treatment device 200 is disposed outside the storage space. The storage space has an air outlet 122 and an air return opening 124, wherein the air outlet 122 communicates with the air inlet section 312 and the air return opening 124 communicates with the air return section 314.

Since the air path assembly 300 can form an air circulation channel between the storage space and the processing portion 220, the gas processing device 200 can be disposed outside the storage space without occupying any storage space, which is beneficial to ensuring the effective volume of the storage space. When the gas processing device 200 is arranged outside the storage space, the temperature of the storage space is hardly affected by the heat generated when the gas processing device 200 operates, and the normal operation of the gas processing device 200 is hardly affected by the low-temperature environment of the storage space, which is beneficial to improving the reliability of the gas processing device 200 and ensuring that the storage space has a high fresh-keeping effect.

When the storage space is an interior space of the storage compartment, the air outlet 122 and the air return opening 124 may be opened in a wall of the storage compartment. When the storage space is an interior space of a storage container disposed in the storage compartment, the air outlet 122 and the air return 124 may open on a wall of the storage container.

In some embodiments, the air inlet section 312 and the air return section 314 are air pipes, and the air outlet 122 and the air return 124 are shaped to match the shapes of the air inlet section 312 and the air return section 314, respectively, so as to achieve a sealing joint and avoid air leakage. For example, the air inlet section 312 and the air return section 314 may be inserted into the air outlet 122 and the air return opening 124 in an interference fit manner, but the sealing engagement manner is not limited thereto. Upon understanding the present embodiments, those skilled in the art should be able to easily make extensions and modifications to the engagement means, and such extensions and modifications should fall within the scope of the present invention.

In some alternative embodiments, the air outlet 122 is located remotely from the return air opening 124. For example, the air outlet 122 and the air return opening 124 may be disposed on different walls of the storage space, or the air outlet 122 and the air return opening 124 may be disposed on the same wall of the storage space and the distance between the air outlet 122 and the air return opening 124 is not less than a preset threshold. The size of the preset threshold is set according to the size of the located wall, and may be, for example, one half to three quarters of the length of the located wall.

With the above structure, the air flows flowing through the air outlet 122 and the air flow flowing through the air return opening 124 do not generate obvious mixed flow, and the air flow flowing out of the air outlet 122 is almost all the air to be treated, thereby providing sufficient raw materials for the treatment part 220 and enabling all the air in the storage space to be treated in a relatively quick and successive way.

In some alternative embodiments, the specific gas component may be oxygen. The gas processing apparatus 200 is an electrolysis apparatus, and the processing portion 220 is a cathode electrode 220 of the gas processing apparatus 200 for consuming oxygen in the storage space by an electrochemical reaction. The electrolysis device is connected with an electrolysis voltage under the condition of electrifying, and carries out electrochemical reaction under the action of the electrolysis voltage. The cathode electrode 220 of the electrolysis device may be connected to a negative electrode of a power source and perform a reduction reaction, in which a reactant includes oxygen, and the reduction reaction may consume oxygen by performing an electrochemical reaction using oxygen as a reactant.

The oxygen in the storage space is treated by the electrolysis device, so that the development concept of low-oxygen preservation can be complied with, the storage life of food materials such as fruits and vegetables is prolonged, and the preservation performance of the refrigerator 10 is improved.

Of course, the electrolysis apparatus is merely one example of the gas processing apparatus 200. The specific gas components that can be processed by the gas processing apparatus 200 may be changed, and the gas processing apparatus 200 may be changed to another apparatus as long as it can perform the gas conditioning function. For example, when the specific gas component is oxygen, the gas processing device 200 may also be an oxygen-rich membrane; when the specific gas component is the odor macromolecule, the gas treatment device 200 may be an adsorption device having an adsorbent.

In the above embodiment, the storage space is the hypoxic space 120, and the number of the hypoxic spaces is one or more. The number of the gas path components 300 is one or more, and the gas path components are arranged in one-to-one correspondence with the hypoxic space 120.

That is to say, one gas path assembly 300 is correspondingly arranged in one low-oxygen space 120, and under the action of the gas path assembly 300, an airflow circulation channel is formed between each low-oxygen space 120 and the processing unit 220, so that the same gas processing device 200 can be used for processing oxygen in a plurality of low-oxygen spaces 120, and the gas processing device has the advantages of high integration degree, high process consistency, simple structure and low cost.

The embodiment shown in fig. 1-2 has one hypoxic space 120 and one gas path assembly 300. Fig. 4 is a schematic structural view of a refrigerator 10 according to another embodiment of the present invention, and fig. 5 is a partial enlarged view of B in fig. 4, where two low oxygen spaces 120 and two gas path assemblies 300 are provided. Each air path assembly 300 is provided with an air flow processing channel 310 respectively communicated with the processing part 220 and corresponding to the low-oxygen space 120, and each air flow processing channel 310 is provided with an air inlet section 312 and an air return section 314 respectively. Each hypoxia space 120 is respectively provided with an air outlet 122 and an air return port 124, wherein the air outlet 122 is communicated with the air inlet section 312 of the corresponding air path assembly 300, and the air return port 124 is communicated with the air return section 314 of the corresponding air path assembly 300.

The number of the hypoxic spaces 120 and the air circuit assemblies 300 can also be any value of three or more, respectively, and those skilled in the art should easily change the relevant structures based on fig. 1 to 2, and therefore the description of the embodiment is omitted.

With the above structure, since the refrigerator 10 has the plurality of different low oxygen spaces 120, different food materials suitable for being stored in a low oxygen fresh-keeping atmosphere can be stored in different regions according to the types of the food materials, so that taint of odors is prevented, and the shelf life of the food materials is further prolonged.

In some alternative embodiments, gas treatment device 200 further includes an anode electrode 230 disposed in correspondence with cathode electrode 220 for providing reactants to cathode electrode 220 via an electrochemical reaction. The anode 230 of the electrolyzer may be connected to the positive electrode of a power source and may perform an oxidation reaction. The cathode 220 and the anode 230 may be immersed in an electrolyte, which may be alkaline, for example, a 1-5 mol/L NaOH solution or a KOH solution.

The type of electrochemical reaction of the anode electrode 230 and the cathode electrode 220 may be set according to actual needs. For example, oxygen in the air may undergo a reduction reaction at the cathode electrode 220, i.e.: o is ₂ +2H ₂ O+4e ^- →4OH ^- OH generated from cathode electrode 220 ^- An oxidation reaction may occur at the anode electrode 230 and oxygen gas may be generated, that is: 4OH ^- →O ₂ +2H ₂ O+4e ^- . That is, in the present embodiment, the anode electrode 230 serves to supply a reactant to the cathode electrode 220 through an electrochemical reaction and generate oxygen.

In some further embodiments, at least one high oxygen space 140 is also formed within the enclosure 100. The refrigerator 10 also has an oxygen gas delivery passage 400 communicating the anode electrode 230 with the high oxygen space 140 for delivering oxygen gas generated by the anode electrode 230 to the high oxygen space 140. For example, the oxygen delivery passage 400 may be a vent tube.

That is, the oxygen generated by the anode 230 can be transported to the high oxygen space 140 through the oxygen transport channel 400, so as to assist the high oxygen space 140 to create a high oxygen atmosphere. For example, a high oxygen atmosphere is suitable for storing parts of meat food materials and the like.

By communicating the anode electrode 230 of the gas processing apparatus 200 with the high oxygen space 140 through the oxygen gas delivery passage 400 and delivering the oxygen gas generated by the anode electrode 230 to the high oxygen space 140, the gas regulating capability of the refrigerator 10 can be improved, so that a low oxygen fresh-keeping atmosphere and a high oxygen fresh-keeping atmosphere can be created at the same time.

In some further embodiments, the gas treatment device 200 has a gas exhaust port 218 for exhausting oxygen generated by the anode electrode 230. Oxygen delivery passageway 400 has a first end 420 connected to exhaust port 218 and a second end 440 connected to hyperoxia space 140. For example, the wall of the high oxygen space 140 may be opened with a fitting opening, and the second end 440 of the oxygen delivery channel 400 may be inserted into the fitting opening in an interference fit manner to achieve a sealing joint and prevent air leakage, but the sealing joint manner is not limited thereto.

In some alternative embodiments, the first end 420 of the oxygen delivery channel 400 has a smaller orifice diameter and the second end 440 has a larger orifice diameter, such that the oxygen delivery channel 400 has a diverging shape in the flow direction of the gas stream, and thus the oxygen can spontaneously and rapidly flow along the flow direction of the gas stream without any gas flow actuation device.

The number of high oxygen spaces 140 may be set according to the actual spatial layout requirements of the refrigerator 10. The number of oxygen delivery channels 400 may be the same as the number of high oxygen spaces 140, and they may be arranged in one-to-one correspondence. For example, when there is one hyperoxide space 140, there is one oxygen delivery channel 400, and the oxygen delivery channel 400 has a first end 420 and a second end 440. When there are multiple hyperoxia spaces 140, there are multiple oxygen delivery channels 400, and each oxygen delivery channel 400 has a first end 420 and a second end 440.

In some embodiments, the structure of oxygen delivery channel 400 may also be altered when there are multiple high oxygen spaces 140. For example, there are a plurality of hyperoxide spaces 140, a plurality of second ends 440 are provided, and are disposed in one-to-one correspondence with the hyperoxide spaces 140, and each of the second ends 440 is an end of a branch pipe extending from the first end 420 to the hyperoxide spaces 140, as shown in fig. 4. That is, the first end 420 of the oxygen supply channel 400 connected to the exhaust port 218 is one, and the oxygen supply channel 400 is provided with branch pipes, and each branch pipe supplies oxygen to the corresponding high oxygen space 140, thereby adjusting the oxygen content of the high oxygen spaces 140.

It should be noted that the hypoxic space 120 can be converted to a hyperoxic space 140, as shown in fig. 4, for example, when it is desired to increase the oxygen content of the space, the gas outlet 122 and the gas return 124 of the space can be closed, and the second end 440 of the oxygen delivery channel 400 can be connected to the hypoxic space 120. When the oxygen content of the space needs to be reduced, the air outlet 122 and the air return opening 124 are opened, and the oxygen conveying channel 400 communicated with the space is closed, so that the function reuse of a certain space can be realized.

In some alternative embodiments, gas treatment device 200 has a housing 210 with a gas flow chamber 214 and an electrolysis chamber 216. Flow chamber 214 communicates with electrolyte chamber 216 through an opening to which a cathode electrode 220 is mounted to space flow chamber 214 from electrolyte chamber 216. That is, cathode electrode 220 separates gas flow chamber 214 from electrolyte chamber 216 by closing the opening. The housing 210 may have a substantially flat rectangular parallelepiped shape and be disposed upright, and the opening may be provided in a longitudinal sectional plane of the housing 210. The area of the opening may be less than or equal to the cross-sectional area of the longitudinal cut plane.

In this embodiment, the gas flow chamber 214 and the electrolyte chamber 216 may be a single piece, and may be integrally formed by a molding process, for example, which may simplify the manufacturing process of the housing 210. In alternative embodiments, gas flow chamber 214 and electrolyte chamber 216 may not be one piece. For example, the electrolytic chamber 216 may have a substantially flat rectangular parallelepiped shape, and the wider side thereof has a mounting opening 211, and the cathode electrode 220 is fitted to the mounting opening 211 to close the electrolytic chamber 216. Gas flow chamber 214 may be generally flat, rectangular parallelepiped in shape with open sides and may be housed on the wider sides of electrolysis chamber 216.

Anode electrode 230 and cathode electrode 220 are disposed in electrolytic chamber 216 at a distance from each other. A reservoir is formed in the electrolyte chamber 216 for holding the electrolyte, and the cathode 220 and the anode 230 are immersed in the electrolyte.

Airflow chamber 214 defines an inlet 214a and an outlet 214b, wherein inlet 214a is in communication with air intake section 312 and outlet 214b is in communication with air return section 314. It should be noted that, when there are a plurality of low-oxygen spaces 120, each air path assembly 300 has an air inlet section 312 and an air return section 314, and accordingly, the airflow chamber 214 needs to be provided with a plurality of sets of inlets 214a and outlets 214b, each set of inlet 214a and outlet 214b is respectively corresponding to one low-oxygen space 120, and is respectively communicated with the air inlet section 312 and the air return section 314 connected to the corresponding low-oxygen space 120.

With the above structure, the gas flow to be treated can be guided to the cathode 220 in order, and the oxygen in the gas flow can participate in the electrochemical reaction at the cathode 220, so that the oxygen is consumed, and the low-oxygen treatment gas flow can be guided to the low-oxygen space 120 in order, and the whole gas flow treatment process is highly ordered, thereby improving the gas flow treatment efficiency.

In the above embodiment, the connection between the gas treatment device 200 and the storage space is illustrated by taking the case where the gas treatment device 200 is disposed on the rear side of the storage space as an example. For example, the gas treatment device 200 may be disposed on an inner surface of a cabinet back of the cabinet 100. The air outlet 122 and the air return 124 of the low oxygen space 120 may be provided on the rear wall of the low oxygen space 120, and the air inlet of the high oxygen space 140 may be provided on the rear wall of the high oxygen space 140.

By virtue of the temperature environment of the press cabin 160, the gas processing apparatus 200 can exert high oxygen removal efficiency and oxygen generation efficiency. In some further embodiments, a portion of the area of the housing 210 may be transformed into a sphere to fit within the interior space of the press cabin 160.

A separator 240 is disposed within the electrolytic chamber 216 between the cathode electrode 220 and the anode electrode 230 for separating the cathode electrode 220 from the anode electrode 230 and preventing short circuiting of the gas treatment device 200. Specifically, a plurality of protrusions 242 are formed on a side of the separator 240 facing the anode electrode 230, the protrusions 242 abut against the anode electrode 230, and the cathode electrode 220 abuts against a side of the separator 240 facing away from the protrusions 242, so as to form a predetermined gap between the cathode electrode 220 and the anode electrode 230, thereby separating the cathode electrode 220 from the anode electrode 230.

The fixing member 250 may be disposed at an outer side of the cathode electrode 220, and configured to fix the cathode electrode 220 at the mounting opening 211 of the case 210. Specifically, the fixing assembly 250 may further include a metal bezel 252 and a support 254.
