Detailed Description
Fig. 1 is a schematic view of a refrigerated freezer 10 according to one embodiment of the present invention. The refrigeration freezer 10 may generally include a cabinet 200 and an oxygen regulating device 100.
The cabinet 200 is formed therein with a storage space 210 for storing articles such as food materials, medicines, drinks, etc. The number of the storage spaces 210 of the present embodiment may be one. In some alternative embodiments, the number of the storage spaces 210 may be changed to a plurality. Each storage space 210 may form a storage compartment. The case 200 may include a housing and an inner container. The inner container is arranged in the box shell, and a storage space 210 is defined in the inner container.
The box body 200 is provided with a mounting port for communicating the storage space 210 with the external environment. For example, a mounting opening may be located on the housing, which may communicate the storage space 210 with the outside environment via a communication channel 510 described below.
The oxygen regulating device 100 is disposed at the installation opening and shields the installation opening, i.e., the oxygen regulating device 100 covers the installation opening to close the installation opening. The outside of the oxygen regulating device 100 is exposed to and in airflow communication with the outside environment, and the inside of the oxygen regulating device 100 is exposed to the interior space of the refrigeration and freezing device 10 and in airflow communication with the storage space 210. In this case, directional terms such as "inside" and "outside" are used with respect to the actual usage state of the refrigeration and freezing apparatus 10.
The oxygen regulating device 100 is used for absorbing oxygen in the external environment and releasing the oxygen to the storage space 210, thereby increasing the oxygen concentration in the storage space 210. For example, the outer side of the oxygen regulating device 100 may absorb oxygen in the external environment, and the inner side may release oxygen to the storage space 210. The direction of the dashed arrows in fig. 1 shows the direction of oxygen flow.
In the refrigeration and freezing device 10 of the present embodiment, since the oxygen regulating device 100 is disposed at the mounting opening formed on the box body 200, the oxygen regulating device 100 can absorb oxygen in the external environment and release the oxygen to the storage space 210, so as to increase the oxygen concentration in the storage space 210, and therefore, the present embodiment provides the refrigeration and freezing device 10 capable of increasing the oxygen concentration in the storage space 210 according to actual needs by improving the structure of the refrigeration and freezing device 10.
Because the oxygen regulating device 100 is arranged at the mounting opening, the mounting and dismounting processes of the oxygen regulating device 100 can be simplified, the operation process is simple and convenient, the dismounting efficiency is improved, and the replacement and the maintenance are convenient.
In some embodiments, the size of the oxygen regulating device 100 may be slightly larger than the opening size of the mounting opening, so that the oxygen regulating device 100 can be covered against the outer periphery or the inner periphery of the mounting opening to shield the mounting opening.
Fig. 2 is a schematic diagram of an oxygen regulating device 100 according to one embodiment of the present invention. In some alternative embodiments, oxygen regulating device 100 includes a cathode plate 120 and an anode plate 140.
The anode plate 140 is in gas flow communication with the reservoir space 210 for releasing oxygen to the reservoir space 210 by electrochemical reaction with the reactant under the action of the electrolysis voltage. For example, OH generated from cathode plate 120-An oxidation reaction may occur at the anode plate 140 and oxygen is generated, i.e.: 4OH-→O2+2H2O+4e-。
In some embodiments, the refrigeration freezer 10 may further include a power module, such as a battery. The power module is disposed near the oxygen regulating device 100 and provides power to the oxygen regulating device 100.
In the refrigerating and freezing apparatus 10 of the present embodiment, since the cathode plate 120 and the anode plate 140 of the oxygen regulator 100 are electrochemically reacted by the electrolytic voltage, the oxygen regulator 100 can be activated to perform the oxygen regulating function only by supplying the power to the oxygen regulator 100. Compared with the scheme of filling oxygen into the storage space 210 by using an oxygen cylinder, the refrigerating and freezing device 10 of the embodiment has a simpler structure, does not need complicated operation in the oxygen adjusting process, and has low manufacturing cost and operation cost.
The oxygen regulating device 100 may further include a housing 110. The housing 110 may have a substantially flat rectangular parallelepiped shape. The housing 110 may have a lateral opening 114 formed therein, and the lateral opening 114 may be located outside the housing 110 and communicate with the external environment. Cathode plate 120 is disposed at lateral opening 114 to define, in conjunction with housing 110, a reservoir for holding electrolyte. The anode plate 140 and the cathode plate 120 are disposed in the liquid storage chamber at intervals.
For example, one of the walls of the housing 110 (e.g., an outer wall of the housing 110) may be open to form a lateral opening 114 opposite the external environment. The cathode plate 120 of this embodiment can be directly used as the outer wall surface of the housing 110 for sealing the liquid storage chamber. The liquid storage cavity of the oxygen regulating device 100 can contain alkaline electrolyte, such as 1mol/L NaOH, and the concentration of the alkaline electrolyte can be adjusted according to actual needs.
The casing 110 may further have an exhaust port 112 for allowing oxygen released from the anode plate 140 to be exhausted. The exhaust port 112 is disposed near the anode plate 140 to facilitate timely and rapid discharge of oxygen released from the anode plate 140. The gas outlet 112 may be used to communicate with a communication passage 510 described below so that oxygen discharged from the gas outlet 112 may enter the storage space 210 via the communication passage 510.
In some optional embodiments, the oxygen regulating device 100 further includes an exhaust pipe 160 having one end connected to the exhaust port 112 and the other end extending into the communication passage 510, so that the exhaust port 112 communicates with the communication passage 510, which may improve the oxygen delivery efficiency, and may also facilitate the connection of the exhaust port 112 to the communication passage 510. The exhaust pipe 160 may form an inner side of the oxygen regulating device 100.
In some optional embodiments, the refrigerating and freezing device 10 may further include an oxygen concentration sensor disposed in the storage space 210 for detecting the oxygen concentration inside the storage space 210. The oxygen regulating device 100 is configured to start when the oxygen concentration in the storage space 210 is lower than a preset concentration threshold, so that the anode plate 140 and the cathode plate 120 respectively perform electrochemical reactions, and thus the oxygen regulating device 100 of the present embodiment can automatically exert an oxygen regulating effect according to the actual oxygen concentration in the storage space 210, which is beneficial to improving the automation level and the intelligence degree of the refrigeration and freezing device 10.
The refrigerating and freezing apparatus 10 may further include a communication member 500 formed with a communication passage 510 communicating between the mounting opening and the storage space 210 for delivering oxygen released from the anode plate 140 to the storage space 210. The communication passage 510 may extend from the mounting opening to the storage space 210. For example, a connection port may be opened on an outer wall of the storage space 210, and the communication channel 510 may extend to the connection port, so as to communicate with the storage space 210.
In some embodiments, the periphery of the mounting opening may be formed with a snap groove. The housing 110 is formed with a jaw, and the position and shape of the jaw are matched with the position and shape of the slot. And the clamping claws are clamped with the clamping grooves to realize detachable connection, which is beneficial to simplifying the dismounting process and the maintenance difficulty of the oxygen adjusting device 100.
In other embodiments, oxygen regulating device 100 may be reversibly disposed at the mounting port such that cathode plate 120 is selectively in gas flow communication with the external environment or storage space 210. For example, when the oxygen concentration in the storage space 210 needs to be increased, the cathode plate 120 is in airflow communication with the external environment, and the anode plate 140 is in airflow communication with the storage space 210, and when the oxygen concentration in the storage space 210 needs to be decreased, the anode plate 140 is in airflow communication with the external environment by turning over the oxygen regulating device 100, and the cathode plate 120 is in airflow communication with the storage space 210.
For example, the oxygen regulating device 100 may be rotatably coupled to the mounting port. The oxygen regulating device 100 may have a rotating shaft that may be collinear with a vertical central axis of the oxygen regulating device 100. The mounting opening is correspondingly provided with a shaft hole for the rotating shaft to extend into so as to realize the rotatable connection of the oxygen regulating device 100.
As another example, the refrigeration and freezing apparatus 10 may further include a driving mechanism in transmission connection with the oxygen regulating device 100 for driving the oxygen regulating device 100 to turn. The driving mechanism may include a motor, and the rotating shaft of the oxygen regulating device 100 may be connected to an output shaft of the motor.
With the oxygen adjusting device 100 being set in a reversible manner, the refrigeration and freezing device 10 of the present embodiment can flexibly adjust the oxygen concentration in the storage space 210, so that the storage space 210 can provide an appropriate fresh-keeping atmosphere for different food materials.
Fig. 3 is a schematic view of a refrigerated freezer 10 according to another embodiment of the present invention. In some alternative embodiments, the number of the storage spaces 210 may be changed to a plurality. For example, the storage space 210 may include a first subspace 211 and a second subspace 212.
The mounting openings communicate with the external environment and the first and second subspaces 211 and 212, i.e., the first and second subspaces 211 and 212 are both in communication with the external environment through the mounting openings, such that the oxygen regulating device 100 is simultaneously in gas flow communication with the first and second subspaces 211 and 212, thereby allowing the anode plate 140 to simultaneously release oxygen to the first and second subspaces 211 and 212 through an electrochemical reaction. The direction of the dashed arrows in fig. 3 shows the oxygen flow direction.
In the refrigerating and freezing device 10 of the present embodiment, since the storage space 210 includes the first subspace 211 and the second subspace 212, and the oxygen regulating device 100 is simultaneously in airflow communication with the first subspace 211 and the second subspace 212, so that the anode plate 140 releases oxygen to the first subspace 211 and the second subspace 212 simultaneously through electrochemical reaction, which realizes sharing of the oxygen regulating device 100, and thus the refrigerating and freezing device 10 of the present embodiment can simultaneously regulate oxygen concentrations of a plurality of storage spaces 210 by using the oxygen regulating device 100.
In this embodiment, two oxygen concentration sensors may be provided, which are respectively disposed in the first subspace 211 and the second subspace 212. The oxygen regulating device may be activated when the oxygen concentration in the first subspace 211 is below a preset concentration threshold, or may be activated when the oxygen concentration in the second subspace 212 is below a preset concentration threshold.
Fig. 4 is a schematic view of a refrigeration freezer 10 according to yet another embodiment of the utility model. Accordingly, the communication member 500 may communicate with the mounting port and between the first subspace 211 and the second subspace 212 for delivering oxygen released from the anode plate 140 to the first subspace 211 and the second subspace 212. The direction of the dashed arrows in fig. 4 shows the oxygen flow direction.
The first subspace 211 and the second subspace 212 may be adjacently disposed. For example, the first subspace 211 and the second subspace 212 are disposed side by side in a horizontal direction or stacked in a vertical direction. The connection port of the first subspace 211 and the connection port of the second subspace 212 may be opened at the boundary of the two subspaces, respectively, to form a common connection port. The communication channel 510 may extend from the mounting port to a junction of the first subspace 211 and the second subspace 212, for example, may extend to an outer peripheral edge of a common connection port of the two subspaces to be in airtight communication with the common connection port, so as to simultaneously communicate the first subspace 211 and the second subspace 212, which enables the communication channel 510 to be shared, which is advantageous to further simplify the structure of the refrigeration freezer 10.
The oxygen regulating device 100 in the above embodiment may further include a partition 130 and a fixing assembly 150. Fig. 5 is an exploded view of the oxygen regulating device shown in fig. 2.
The separator 130 is disposed in the liquid storage chamber and located between the cathode plate 120 and the anode plate 140 for separating the cathode plate 120 and the anode plate 140 to prevent the oxygen regulating device 100 from short-circuiting. Specifically, the separator 130 has a plurality of protrusions 132 formed on a side thereof facing the anode plate 140, the protrusions 132 abut against the anode plate 140, and the cathode plate 120 abuts against a side of the separator 130 facing away from the protrusions 132 to form a predetermined gap between the cathode plate 120 and the anode plate 140, thereby separating the cathode plate 120 from the anode plate 140.
A fixing assembly 150 may be provided at the outer side of cathode plate 120, configured to fix cathode plate 120 at lateral opening 114 of case 110. Specifically, the fixing assembly 150 may further include a metal bezel 152 and a support 154.
The support member 154 is formed with a socket. When the surrounding portions 152a of the metal frame 152 are inserted into the insertion grooves of the support members 154, the metal frame 152 can be fixed and positioned by the support members 154, thereby allowing the metal frame 152 to press against the cathode plate 120.
In the refrigeration and freezing device 10 of the present embodiment, since the oxygen regulating device 100 is disposed at the mounting opening formed on the box body 200, the oxygen regulating device 100 can absorb oxygen in the external environment and release the oxygen to the storage space 210, so as to increase the oxygen concentration in the storage space 210, and therefore, the present embodiment provides the refrigeration and freezing device 10 capable of increasing the oxygen concentration in the storage space 210 according to actual needs by improving the structure of the refrigeration and freezing device 10.
