Detailed Description
Fig. 1 is a schematic structural view of a refrigerator 10 according to an embodiment of the present invention. The refrigerator 10 may generally include a cabinet 110 and an oxygen regulating device 300.
The cabinet 110 has a storage space 122 and a cooling air duct 130 for circulating cooling air to provide cooling energy to the storage space 122. The storage space 122 refers to a space for storing articles. For example, the interior of the cabinet 110 may define a storage compartment 112, and the storage space 122 may refer to an interior space of the storage compartment 112, or may refer to an interior space of the storage container 120 disposed within the storage compartment 112.
The relative position between the cooling air duct 130 and the storage space 122 can be set according to actual needs. The flow of the refrigerant gas flowing through the refrigerant duct 130 may flow through the inside of the storage space 122 or through the outer circumference of the storage space 122, thereby providing the cold energy to the storage space 122. For example, the cooling air duct 130 may be an air supply duct disposed at one side of the storage space 122 and in air flow communication with the storage space 122 through an air supply opening and an air outlet, so that the cooling air flowing through the cooling air duct 130 flows into the storage space 122 through the air supply opening and flows out from the air outlet after flowing through the storage space 122. For another example, the cooling air duct 130 may be an additional dedicated air duct that is communicated with the air supply air duct, and the cooling air duct 130 may be located at the periphery of the storage space 122, so that the cooling air flowing through the cooling air duct 130 exchanges heat with the storage space 122.
The oxygen regulating device 300 is disposed on a flow path of the cooling air flowing through the cooling air duct 130, and is used for regulating the oxygen content of the storage space 122. The arrangement of oxygen regulating device 300 in the flow path of the refrigerant gas stream means that oxygen regulating device 300 is arranged at a position through which the refrigerant gas stream can flow.
For example, oxygen regulating device 300 may be disposed within refrigeration air duct 130, and the flow of refrigeration air through refrigeration air duct 130 would obviously flow through oxygen regulating device 300. However, the flow path of the cooling air flow is not limited to the inside of the cooling air duct 130, and the cooling air flow flowing out of the cooling air duct 130 may continue to flow. For another example, the oxygen adjusting device 300 may also be disposed outside the cooling air duct 130 and on the flow path of the cooling air flow flowing out of the cooling air duct 130, that is, the cooling air flow flowing through the cooling air duct 130 may flow through the oxygen adjusting device 300 after flowing out of the cooling air duct 130.
In the refrigerator 10 of the present embodiment, since the oxygen regulating device 300 is disposed on the flow path of the cooling airflow flowing through the cooling air duct 130, the cooling capacity carried by the cooling airflow can cool the oxygen regulating device 300 and the surrounding environment thereof, and therefore, the oxygen regulating device 300 of the refrigerator 10 can reduce or avoid significant influence on the temperature of the local area. The oxygen regulating process can be carried out under safe and reliable conditions, the phenomenon that the oxygen control loses the temperature control can not occur, and the popularization and the application of the oxygen regulating technology can be promoted.
The oxygen regulating device 300 may regulate the oxygen content of the storage space 122 by performing an electrochemical reaction. For example, the oxygen regulating device 300 may include an electrolytic case 310, a cathode portion 322, and an anode portion 321. The electrolytic case 310 has an electrolytic chamber 312 for containing an electrolyte therein, and the cathode portion 322 and the anode portion 321 may be plate-shaped electrodes respectively, and are disposed to be immersed in the electrolyte contained in the electrolytic chamber 312 for treating oxygen by performing an electrochemical reaction under an electrolytic voltage.
For example, oxygen in the air may undergo a reduction reaction at the cathode portion 322, that is: o is 2 +2H 2 O+4e - →4OH - . OH generated from the cathode portion 322 - An oxidation reaction may occur at the anode portion 321, and oxygen gas may be generated, that is: 4OH - →O 2 +2H 2 O+4e - . The anode portion 321 utilizes OH - While the electrochemical reaction is taking place, a reactant, such as an electron e, is supplied to the cathode portion 322 - 。
At least a portion of the oxygen regulating device 300 may be in gas flow communication with the storage space 122 to regulate the oxygen content of the storage space 122. For example, the cathode portion 322 may be in airflow communication with the storage space 122, in which case the oxygen content of the storage space 122 may be reduced by the electrochemical reaction of the cathode portion 322. For another example, the electrolytic housing 310 may be opened with an exhaust port 314 for exhausting oxygen generated by the anode portion 321, the exhaust port 314 may be in airflow communication with the storage space 122, and at this time, the oxygen flowing out of the exhaust port 314 may be guided to the storage space 122, so as to increase the oxygen content of the storage space 122.
The above "gas flow communication" may refer to communication in a direct or indirect manner. The storage space 122 may be opened with a communication port communicating with the outside thereof. For example, when the cathode portion 322 is in airflow communication with the storage space 122, the cathode portion 322 may at least partially cover the communication opening to be in direct airflow communication with the storage space 122 through the communication opening. As another example, when the exhaust port 314 is in airflow communication with the storage space 122, the exhaust port 314 may be plugged into the communication port to be in direct airflow communication with the storage space 122 through the communication port. When the communication is performed indirectly, the communication port and the cathode portion 322 and the communication port and the exhaust port 314 may be connected by a pipe.
Of course, the structure of the oxygen adjusting device 300 and the means for adjusting oxygen are not limited thereto. With the understanding of the embodiments, those skilled in the art should easily extend the technical solution of the present embodiment to the refrigerator 10 having other types of oxygen adjusting devices 300 (for example, the oxygen adjusting device 300 adjusting the oxygen content based on the oxygen enrichment membrane principle or based on the adsorption-desorption principle, etc.).
Fig. 3 is an internal structure view of the refrigerator 10 according to an embodiment of the present invention. Storage space 122, oxygen treatment device, and refrigerated air duct 130 are shown. The cooling duct 130 is located at one side of the storage space 122 and configured to output a cooling air flow through the air supply outlet so that the cooling air flow provides cooling energy to the storage space 122.
In this embodiment, the cooling air duct 130 may actually be an air supply duct of the refrigerator 10. For example, the refrigerator 10 may further include a duct cover having a front side defining the storage space 122 and a rear side defining the cooling duct 130. The air outlet end of the cooling air duct 130 forms at least one air supply outlet. The air supply outlet can be arranged on the air duct cover plate.
The oxygen adjusting device 300 is opposite to the air supply opening. Oxygen regulating device 300 may be disposed in the space between storage space 122 and refrigerated air duct 130. A storage space 122 may be defined inside the storage container 120. The storage container 120 may be disposed at a front side of the air duct cover plate and spaced apart from the air duct cover plate to arrange the oxygen adjusting device 300. At this time, a communication port may be opened in the rear wall of the container 120 so as to be in air flow communication with the cathode portion 322 of the oxygen adjusting device 300 through the communication port, while the cathode portion 322 shields the communication port.
Fig. 4 is an internal structure view of a refrigerator 10 according to another embodiment of the present invention. Storage space 122, oxygen treatment device, and refrigerated air duct 130 are shown. In this embodiment, the refrigerated air duct 130 is disposed at least partially around the storage space 122 such that the refrigerated air flow provides refrigeration to the storage space 122 via heat transfer.
Because the cooling air duct 130 at least partially surrounds the storage space 122 and provides cooling energy to the storage space 122 through heat transfer, the cooling air flow does not directly contact the food material in the storage space 122, so that the effects of reducing or preventing the food material in the storage space 122 of the refrigerator 10 from losing moisture and enhancing the fresh-keeping effect can be achieved.
An air supply duct is formed in the cabinet 110 at one side of the storage space 122 for supplying a cooling air flow to the cooling air duct 130. The supply air duct communicates with the cooling air duct 130 through the air inlet 132 and the air return 134, so that the cooling air flowing through the supply air duct flows into the cooling air duct 130 at least partially surrounding the storage space 122 through the air inlet 132, and returns to the supply air duct from the air return 134 after flowing through the cooling air duct 130.
That is, the cooling air duct 130 is not an inherent supply air duct of the refrigerator 10, but is an additional dedicated air duct communicated with the supply air duct, and the cooling air duct 130 may be located at the periphery of the storage space 122, so that the cooling air flowing through the cooling air duct 130 exchanges heat with the storage space 122 through heat transfer.
The air inlet 132 forms an air inlet end of the cooling air duct 130, and the air return 134 forms an air outlet end of the cooling air duct 130. For example, the air inlet 132 may be connected to the supply air duct through one or more air supply ports, and the air return 134 may be connected to the supply air duct through other air supply ports. The air inlet 132 and the air return 134 are respectively disposed at the rear side of the storage space 122 to shorten the distance between the air inlet and the air supply duct.
By additionally arranging the special refrigeration air duct 130, which is equivalent to extending the air supply air duct to the periphery of the storage space 122, the refrigeration air flow can directionally flow along the special refrigeration air duct 130, so that the refrigeration air flow flowing through the refrigeration air duct 130 has higher flow, sufficient heat transfer between the refrigeration air flow and the storage space 122 is ensured, and the refrigeration effect is enhanced. In addition, the refrigeration of the storage space 122 can be independently controlled, so that the temperature range of the storage space 122 can be flexibly adjusted, which is beneficial to improving the fresh-keeping effect of the storage space 122.
For example, in some embodiments, the cooling air duct 130 may be disposed around the storage space 122, in other words, all of the storage space 122 is surrounded by the cooling air duct 130, which may increase the contact area between the heat exchange air flow and the storage space 122, and improve the heat transfer efficiency. At this point, the walls of the modified storage space 122 are actually hollow and double-layered.
Because the refrigeration air duct 130 is wrapped outside the storage space 122, the refrigeration air duct 130 is equivalent to a hollow heat insulation interlayer, and even though the refrigeration air flow does not flow through the refrigeration air duct 130, the hollow heat insulation interlayer can also play a role in slowing down the temperature fluctuation of the storage space 122, so that the storage space 122 of the refrigerator 10 has a better heat preservation effect.
When the cooling air duct 130 is an additional dedicated air duct, the oxygen regulating device 300 may be disposed in the cooling air duct 130 and in airflow communication with the storage space 122 to consume oxygen in the storage space 122 or provide oxygen to the storage space 122, so as to reduce or increase oxygen content in the storage space 122.
The oxygen adjusting device 300 may be disposed at any position in the cooling air duct 130, as long as it is ensured that the position has enough accommodating space for disposing the oxygen adjusting device 300, and the oxygen adjusting device 300 disposed at the position can be in air flow communication with the storage space 122, for example, through a communication port.
For example, in some alternative embodiments, the refrigerated air duct 130 has a rear section that wraps around the rear side of the storage space 122. Oxygen regulating device 300 may be disposed in a rear section, i.e., a section of refrigerated air duct 130 located behind storage space 122. With such an arrangement, the oxygen regulating device 300 can be arranged at a position which is not easily touched by a user, so that the user is prevented from touching the oxygen regulating device 300 when the user performs an action of taking and placing articles.
The oxygen regulating device 300 is arranged in the cooling air duct 130, the flowing cooling air flow is used for cooling the oxygen regulating device 300 and the surrounding environment thereof, the oxygen regulating device 300 needing to be cooled and the surrounding environment thereof can be cooled in a targeted mode, a good cooling effect is achieved, and the outward diffusion of heat generated by electrochemical reaction of the oxygen regulating device 300 can be reduced or avoided.
In some alternative embodiments, the refrigerator 10 may further include a storage container 120 and a sealing case 150. Wherein the inside of the storage container 120 defines the storage space 122. The sealing housing 150 covers at least a portion of the wall of the storage container 120, and has a gap with the storage container 120, and the gap forms the cooling air duct 130.
For example, the sealing housing 150 may cover and buckle the top wall, the bottom wall, the rear wall, and the two side walls of the storage container 120, and have a gap with each of the above walls of the storage container 120, respectively, to form the cooling air duct 130. The air inlet 132 and the air return 134 are disposed on the hermetic case 150.
In some further embodiments, the storage container 120 may be a drawer and has a drawer barrel 124 defining a forward opening and a drawer body 126 retractably disposed within the drawer barrel 124. The seal housing 150 has a seal cylindrical shape with a forward opening, and is wrapped around the outside of the drawer cylinder 124 to form a gap with each wall of the drawer cylinder 124.
The sealing housing 150 with the forward opening is covered and buckled at the outer side of the drawer cylinder 124 with the forward opening, so that the refrigerating air duct 130 can be additionally arranged under the condition that the opening and closing mode of the storage space 122 is not changed, and the refrigerating mode of the storage space 122 is adjusted to perform heat exchange with the refrigerating air flow flowing through the refrigerating air duct 130.
The drawer body 126 closes the forward opening of the drawer cylinder 124 and also closes the forward opening of the hermetic casing 150, so that the refrigerating duct 130 communicates with the outside only through the intake opening 132 and the return opening 134. For example, the area of the front panel of the drawer body 126 may be slightly larger than the area of the front opening of the seal housing 150, so that the drawer body 126 can close the front opening of the seal housing 150 when closing the front opening of the drawer cylinder 124. The periphery of the forward opening of the seal housing 150 may be provided with a gasket that seals by pressing against the front panel when the drawer body 126 closes the forward opening of the seal housing 150.
When the oxygen regulating device 300 is used to reduce the oxygen content in the storage space 122, the cathode portion 322 is in airflow communication with the storage space 122, and if the oxygen concentration in the storage space 122 is higher than a first predetermined concentration threshold, the oxygen regulating device 300 can be controlled to start, so that the anode portion 321 and the cathode portion 322 are respectively connected to the electrolysis voltage and respectively perform electrochemical reactions, so that the cathode portion 322 consumes the oxygen in the storage space 122. When the oxygen adjusting device 300 is activated, the refrigerator 10 may activate the refrigeration system for the storage space 122, and the air inlet 132 and the air return 134 of the refrigeration air duct 130 are respectively opened to make the refrigeration air flow into the refrigeration air duct 130, so as to prevent the heat generated by the operation of the oxygen adjusting device 300 from damaging the low-temperature environment of the storage space 122.
It should be noted that, only when the oxygen adjusting device 300 is started, the refrigeration system for the storage space 122 is started together and the air inlet 132 and the air return 134 of the refrigeration air duct 130 are opened, and after the oxygen adjusting device 300 is started, the refrigeration system, the air inlet 132 and the air return 134 and the oxygen adjusting device 300 can be controlled separately. In some alternative embodiments, when the temperature of the storage space 122 reaches below the preset first temperature threshold, the air inlet 132 and the air return 134 of the cooling air duct 130 may be closed, or the cooling system for the storage space 122 may be closed at the same time. When the temperature of the storage space 122 reaches above the preset second temperature threshold, the refrigeration system for the storage space 122 may be started again, and the air inlet 132 and the air return 134 of the refrigeration air duct 130 are opened. When the oxygen concentration in the storage space 122 is lower than the preset second concentration threshold, the oxygen adjusting device 300 may be turned off.
Fig. 4 is a schematic structural view of an oxygen regulating device 300 of the refrigerator 10 according to an embodiment of the present invention. Fig. 5 is a schematic exploded view of the oxygen regulating device 300 of the refrigerator 10 shown in fig. 4, showing the electrolytic case 310 and the anode portion 321.
The oxygen regulating device 300 may generally include an electrolytic housing 310, a cathode portion 322, and an anode portion 321.
The electrolytic housing 310 is provided with an assembling opening. The cathode portion 322 is disposed at the mounting port to define an electrolytic chamber 312 for holding an electrolyte together with the electrolytic case 310. And the cathode portion 322 is configured to consume oxygen by performing an electrochemical reaction. The anode 321 and cathode 322 are disposed in the electrolytic chamber 312 at an interval from each other, and are configured to generate oxygen by performing an electrochemical reaction.
By adopting the structure, the refrigerator 10 can treat the oxygen in the storage space 122 so as to conform to the development concept of low-oxygen preservation, prolong the storage life of food materials such as fruits and vegetables and improve the preservation performance of the refrigerator 10.
