Detailed Description
Fig. 1 is a schematic block diagram of a refrigerator 10 according to one embodiment of the present invention. The refrigerator 10 may generally include a cabinet 100, a gas treatment device 200, and a gas circuit assembly 300.
The interior of the case 100 defines a storage space 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 storage basket, etc.) disposed within the storage space.
The gas treatment device 200 is disposed in the case 100 and has a treatment portion 220, and the treatment portion 220 is in gas flow communication with the storage space and is used for treating 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 circuit assembly 300 has an air flow processing passage 310 communicating with the processing portion 220 and the storage space. Under the guidance of the air path assembly 300, the air in the storage space can flow through the air flow treatment channel 310 and flow to the treatment part 220, and then return to the storage space after being treated by the treatment part 220.
The gas flow treatment channel 310 has an intake section 312 and a return section 314. The air inlet section 312 is connected between the storage space and the processing portion 220 and is used for delivering the air flow 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 delivering the air flow processed by the processing portion 220 to the storage space.
According to the scheme of the embodiment, the air path assembly 300 is arranged, the air flow treatment channel 310 of the air path assembly 300 is communicated with the treatment part 220, the air inlet section 312 and the air return section 314 are constructed in the air flow treatment channel 310, the air flow from the storage space is conveyed to the treatment part 220 by the air inlet section 312, the air flow treated by the treatment part 220 is conveyed to the storage space by the air return section 314, and an air flow circulation channel is formed between the storage space and the treatment part 220, so that the air flow circulation performance of an air conditioning process is improved, and the air conditioning efficiency is optimized.
Since the air flow to be treated flows to the treatment part 220 through the air inlet section 312 and the air flow after being treated returns 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 the air flow to be treated and the air flow after being treated are not obviously mixed, so that the air flow after being treated is reduced or prevented from being mixed into the air flow to be treated, and the air conditioning efficiency is ensured.
In this embodiment, the air circuit assembly 300 is utilized to construct an air flow treatment channel, so that an active circulation air circuit can be formed between the storage space and the air treatment device 200, and the air flow rate and the flow order of the air conditioning process are enhanced.
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 at a in fig. 2.
In some alternative embodiments, the air circuit assembly 300 further has an air flow actuation device 320 in air circuit communication with the air flow treatment channel 310 for causing an air flow to be established through the air inlet section 312, the treatment portion 220, the air return section 314, and the storage space in that order. Under the action of the airflow actuating device 320, the airflow flowing rate in the airflow circulation channel can be increased, so that the airflow to be treated in the storage space flows to the treatment part 220 in a 'sequential' manner, and the air conditioning efficiency is improved.
The airflow actuation device 320 is disposed proximate to the intake section 312. For example, an air outlet of the air flow actuating device 320 may be connected to an air inlet end of the air inlet section 312, and an air inlet of the air flow actuating device 320 may be connected to the air outlet 122 of the storage space, which is beneficial to improving the air flow actuating effect, thereby accelerating the air flow circulation rate.
In some embodiments, the airflow actuating device 320 may be an axial flow fan or a centrifugal fan, but is not limited thereto as long as it can function to guide the directional flow of the airflow.
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 124, wherein the air outlet 122 communicates with an air inlet section 312 and the air return 124 communicates with an air return section 314.
Because the air circuit assembly 300 is utilized to form an air circulation channel between the storage space and the processing portion 220, the air processing device 200 can be disposed outside the storage space, and does not occupy any storage space, which is beneficial to ensuring the effective volume of the storage space. When the gas treatment device 200 is arranged outside the storage space, heat generated during operation of the gas treatment device 200 hardly affects the temperature of the storage space, and the low-temperature environment of the storage space hardly affects the normal operation of the gas treatment device 200, so that the reliability of the gas treatment device 200 is improved, and the storage space is guaranteed to have a higher fresh-keeping effect.
When the storage space is the inner space of the storage compartment, the air outlet 122 and the air return 124 may be provided in the wall of the storage compartment. When the storage space is an inner space of a storage container disposed in the storage compartment, the air outlet 122 and the air return 124 may be opened on a wall of the storage container.
In some embodiments, the air inlet section 312 and the air return section 314 are ventilation pipes, respectively, and the air outlet 122 and the air return 124 are shaped to fit the contours of the air inlet section 312 and the air return section 314, respectively, to achieve a sealed engagement to 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 124, respectively, in an interference fit, but the sealing engagement is not limited thereto. Those skilled in the art should easily develop and transform the joining means on the basis of the present embodiment, and these develop and transform should all fall within the protection scope of the present invention.
In some alternative embodiments, the air outlet 122 is disposed remote from the air return 124. For example, the air outlet 122 and the air return 124 may be disposed on different walls of the storage space, or the air outlet 122 and the air return 124 may be disposed on the same wall of the storage space and the distance between the air outlet 122 and the air return 124 is not less than a preset threshold. The magnitude of the preset threshold is set according to the size of the wall, and may be, for example, one half to three quarters of the length of the wall.
With the above structure, the air flows flowing through the air outlet 122 and the air return 124 do not generate obvious mixed flow, and almost all the air flowing out of the air outlet 122 is the air to be treated, so that sufficient raw materials are provided for the treatment part 220, and all the air in the storage space can be treated rapidly.
In some alternative embodiments, the specific gas component may be oxygen. The gas treatment device 200 is an electrolysis device, and the treatment unit 220 is a cathode electrode 220 of the gas treatment device 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 performs electrochemical reaction under the action of the electrolysis voltage. The cathode electrode 220 of the electrolysis apparatus may be connected to a negative electrode of a power source and perform a reduction reaction, and a reactant of the reduction reaction includes oxygen, which serves to consume oxygen by performing an electrochemical reaction using oxygen as a reactant.
The oxygen in the storage space is treated by adopting the electrolysis device, so that the development concept of low-oxygen preservation can be complied, the preservation period of food materials such as fruits and vegetables can be prolonged, and the preservation performance of the refrigerator 10 can be improved.
Of course, the electrolyzer is merely one example of a gas processing device 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 the gas conditioning function is enabled. For example, when the particular gas component is oxygen, the gas treatment device 200 may also be an oxygen-enriched membrane; when the specific gas component is a large odor molecule, the gas treatment apparatus 200 may be an adsorption apparatus having an adsorbent.
In the above embodiment, the storage space is the hypoxic space 120, and the number thereof is one or more. The number of the air circuit components 300 is one or more, and the air circuit components are arranged in one-to-one correspondence with the low-oxygen space 120.
That is, one of the low-oxygen spaces 120 is correspondingly provided with one gas path assembly 300, and under the action of the gas path assembly 300, an air flow circulation channel can be formed between each low-oxygen space 120 and the processing part 220, so that the same gas processing device 200 can be utilized to process the oxygen in a plurality of low-oxygen spaces 120, and the device has the advantages of high integration degree, high process consistency, simple structure and low cost.
The embodiment of fig. 1-2 shows one hypoxic space 120 and one gas circuit 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 partially enlarged view of B in fig. 4, in which there are two low oxygen spaces 120 and two gas path assemblies 300. Each gas circuit assembly 300 has a gas flow treatment channel 310 in communication with the treatment portion 220 and the corresponding low oxygen space 120, respectively, each gas flow treatment channel 310 having a gas inlet section 312 and a gas return section 314, respectively. Each hypoxic space 120 is provided with an air outlet 122 and an air return 124, wherein the air outlet 122 is communicated with an air inlet section 312 of the corresponding air path assembly 300, and the air return 124 is communicated with an air return section 314 of the corresponding air path assembly 300.
The number of the hypoxic space 120 and the gas circuit assembly 300 can be any value of three or more, and those skilled in the art should easily change the related structures based on fig. 1 to 2, so the description of this embodiment is omitted.
With the above structure, since the refrigerator 10 has a 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 the cross-taste 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 a reactant to cathode electrode 220 via an electrochemical reaction. The anode electrode 230 of the electrolysis apparatus may be connected to the positive electrode of the power source and perform an oxidation reaction. The cathode electrode 220 and the anode electrode 230 may be immersed in an electrolyte, which may be alkaline, such as 1 to 5mol/L NaOH solution or KOH solution, or the like.
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, namely: o (O) 2 +2H 2 O+4e - →4OH - OH generated by cathode electrode 220 - Can be used forAn oxidation reaction may occur at the anode electrode 230 and oxygen is generated, namely: 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 further has an oxygen delivery passage 400 communicating the anode electrode 230 with the high oxygen space 140 for delivering oxygen 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, oxygen generated from the anode electrode 230 may be transported to the high oxygen space 140 through the oxygen transport passageway 400, thereby assisting the high oxygen space 140 in creating a high oxygen atmosphere. For example, a high oxygen atmosphere is suitable for storing a portion of meat food material, and the like.
By communicating the anode electrode 230 of the gas treatment apparatus 200 with the high oxygen space 140 by the oxygen transmission passage 400 and transmitting the oxygen generated by the anode electrode 230 to the high oxygen space 140, the air conditioning capacity of the refrigerator 10 can be improved to create a low oxygen fresh-keeping atmosphere and a high oxygen fresh-keeping atmosphere at the same time.
In some further embodiments, the gas treatment device 200 has an exhaust port 218 for exhausting oxygen generated by the anode electrode 230. The oxygen delivery passageway 400 has a first end 420 connected to the exhaust port 218 and a second end 440 connected to the plenum 140. For example, the wall of the high oxygen space 140 may be provided with a fitting opening, and the second end 440 of the oxygen delivery channel 400 may be inserted into the fitting opening by an interference fit to achieve sealing engagement, so as to prevent air leakage, but the sealing engagement method 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 direction of flow of the gas stream, and thus, oxygen can spontaneously flow rapidly in the direction of flow of the gas stream without the need for any gas flow actuating device.
The number of the high oxygen spaces 140 may be set according to the actual space layout requirements of the refrigerator 10. The number of the oxygen delivery channels 400 and the number of the high oxygen spaces 140 may be the same and are arranged in one-to-one correspondence. For example, when the high oxygen space 140 is one, the oxygen delivery channel 400 is one, and the oxygen delivery channel 400 has a first end 420 and a second end 440. When the high oxygen space 140 is plural, the oxygen delivery channels 400 are plural, and each oxygen delivery channel 400 has a first end 420 and a second end 440, respectively.
In some embodiments, when the high oxygen space 140 is plural, the structure of the oxygen delivery channel 400 may also be changed. For example, the number of the high-oxygen spaces 140 is plural, the number of the second ends 440 is plural, and the second ends 440 are disposed in one-to-one correspondence with the high-oxygen spaces 140, and each of the second ends 440 is a terminal of a branch pipe extending from the first end 420 to the high-oxygen space 140, as shown in fig. 4. That is, the first end 420 of the oxygen delivery channel 400 connected to the exhaust port 218 is one, and the oxygen content of the plurality of high oxygen spaces 140 can be adjusted simultaneously by adding branch pipes to the oxygen delivery channel 400 and making each branch pipe deliver oxygen to the corresponding high oxygen space 140.
It should be noted that, as shown in fig. 4, the low oxygen space 120 may be converted into the high oxygen space 140, for example, when the oxygen content of the space needs to be increased, the air outlet 122 and the air return 124 of the space may be closed, and the second end 440 of the oxygen delivery channel 400 may be connected to the low oxygen space 120. When the oxygen content of the space needs to be reduced, the air outlet 122 and the air return 124 are opened, and the oxygen transmission channel 400 communicated with the space is closed, so that the function multiplexing of a certain space can be realized.
