Detailed Description

Fig. 1 is a schematic structural view of a refrigerator 10 according to an embodiment of the present invention. Fig. 2 is a schematic side view of a refrigerator 10 according to an embodiment of the present invention, and fig. 2 is drawn in a perspective view in order to better show the internal structure of the refrigerator 10.

The refrigerator 10 generally can include a liner 110 and an electrolytic deoxygenator device 200. The inner container 110 is a component of the refrigerator 10 and the cabinet 100, for example, may form the cabinet 100 together with the cabinet 120. The inner container 110 has a storage compartment 112 formed therein. The storage compartment 112 may be one or more. The electrolytic oxygen removal device 200 may be selectively disposed in a storage compartment 112, such as a refrigeration compartment, a freezing compartment, or a temperature-changing compartment, without limitation.

The electrolytic oxygen removal device 200 is disposed at an angle to the bottom of the storage compartment 112 and is used to consume oxygen in the storage compartment 112 by performing an electrochemical reaction under the action of an electrolytic voltage. For example, the electrolytic oxygen removal device 200 may include a cathode electrode and an anode electrode, at which electrochemical reactions may occur, respectively, by energizing the cathode electrode and the anode electrode. The type of electrochemical reaction can be chosen arbitrarily, as long as it is ensured that the reactant of one electrode is oxygen. For example, the electrochemical reaction at the cathode electrode may be a reduction reaction, and the electrochemical reaction at the anode electrode may be an oxidation reaction.

In the refrigerator 10 of the present embodiment, the electrolytic oxygen removing device 200 is used to consume oxygen in the storage compartment 112, and the electrolytic oxygen removing device 200 has the advantage of small volume, so that the refrigerator 10 does not occupy too much space, and the refrigerator 10 has a low-oxygen fresh-keeping function and simultaneously can ensure the effective volume of the refrigerator 10. By providing the electrolytic oxygen removal device 200 obliquely at the bottom of the storage compartment 112, the appearance and configuration of the refrigerator 10 in the lateral and depth directions can be further prevented from being affected by the installation of the electrolytic oxygen removal device 200.

The electrolytic oxygen removal device 200 is arranged at the bottom of the storage chamber 112, so that the bottom space of the chamber can be fully utilized, for example, the electrolytic oxygen removal device 200 can be suitably arranged at the bottom of the storage chamber 112 by improving the installation posture of the electrolytic oxygen removal device 200, and the effects of reducing the occupied space and ensuring the effective volume are achieved. By being inclined, the electrolytic oxygen removal device 200 can be extended in a narrow installation space, thereby ensuring that electrochemical elements (such as a cathode electrode and an anode electrode) have appropriate active areas and thus considerable oxygen removal efficiency.

In some alternative embodiments, the refrigerator 10 may further include a storage container 300 disposed in the storage compartment 112, and a return air gap 114 is formed between a bottom wall of the storage container 300 and a bottom wall of the storage compartment 112. The return air gap 114 allows the flow of return air through the storage compartment 112. The bottom wall of the storage container 300 is provided with a mounting opening 312. The mounting opening 312 serves as a communication opening between the electrolytic oxygen removing device 200 and the internal space of the storage container 300.

The electrolytic oxygen removal device 200 is disposed in the return air gap 114 and closes the mounting opening 312 and is used to consume oxygen in the storage container 300 by performing an electrochemical reaction. For example, the cathode electrode of the electrolytic oxygen removing device 200 can cover or be clamped on the periphery of the mounting opening 312, so that the electrochemical reaction can be performed by using the oxygen in the container 300 as a reactant while the mounting opening 312 is closed.

Because the electrolytic oxygen removing device 200 can be arranged in the return air gap 114 between the bottom wall of the storage compartment 112 and the bottom wall of the storage container 300, the electrolytic oxygen removing device 200 does not directly contact with the inner space of the storage container 300, and therefore, based on the scheme of the embodiment, the electrolytic oxygen removing device 200 is not damaged in the process of taking and placing articles by a user, which is beneficial to improving the convenience and reliability of the refrigerator 10 in the using process. In some embodiments, the side of the mounting opening 312 facing into the storage container 300 may be provided with a mesh having air permeability and spacing to prevent the articles from falling onto the cathode electrode of the electrolytic oxygen removal device 200.

By placing the electrolytic deoxygenator device 200 within the return air gap 114, safety hazards due to excessive temperatures of the electrolytic deoxygenator device 200 and surrounding components can be reduced or avoided, as the return air stream can flow through the electrolytic deoxygenator device 200 and remove some of the heat from the electrolytic deoxygenator device 200.

FIG. 3 is an enlarged view of a portion of FIG. 2 at A; fig. 4 is another enlarged view of a portion a of fig. 2, with electrolytic oxygen removal device 200 hidden in fig. 4 as compared to fig. 3.

In some alternative embodiments, a portion of the bottom wall of the storage compartment 112 is recessed downward to form a recess 114a in the return air gap 114 opposite the mounting opening 312. And electrolytic oxygen removal device 200 is disposed at recess 114a. That is, the bottom wall of the storage compartment 112 is deformed to form a recess 114a, and the recess 114a can provide a sufficient space for installing the electrolytic oxygen removing device 200. For example, the recess 114a and the storage compartment 112 can be formed in one step by modifying the forming process of the inner container 110.

With the above structure, the refrigerator 10 can make room for the electrolytic oxygen removing device 200 to be installed, and has a delicate structure, and hardly has adverse effects on the effective volume and aesthetic appearance of the refrigerator 10.

In some optional embodiments, the refrigerator 10 may further include a stopper assembly disposed at the groove 114a and defining a detent for snap-positioning the electrolytic deoxygenator device 200, the detent being configured to allow the electrolytic deoxygenator device 200 to be tilted at a predetermined angle relative to the horizontal while closing the mounting opening 312. Wherein, screens refer to the positioning space of the electrolytic oxygen removing device 200. When the electrolytic deoxygenator device 200 is snapped and positioned in the detent defined by the limiting assembly, the mounting opening 312 is properly closed and is inclined at a predetermined angle to the horizontal plane. Wherein the preset angle is any value in the range of 0 to 45 °, such as 15 ° or 30 °.

The electrolytic oxygen removal device 200 is positioned by the limiting assembly, the method is simple and convenient, the structure is simple, the positioning precision of the electrolytic oxygen removal device 200 can be ensured, and the problems that the mounting port 312 is not tight in sealing and the like are prevented.

In some further embodiments, the stop assembly includes first and

second stop ledges

410, 420 extending upwardly from the floor of the recess 114a, and a third stop ledge 430 extending downwardly from the rear end of the perimeter wall of the mounting opening 312. Each limit protruding edge can be plate-shaped, and the plate surface extends along the transverse direction of the box body 100.

The detents defined by the stop assembly can include a first detent 401 and a second detent 402. Each detent serves as a positioning space for a portion of the snap-fit positioning electrolytic oxygen removal device 200. The first and third limiting

protrusions

410 and 430 are opposite to each other, and a first stopper 401 is formed by a gap between the first and third limiting protrusions 430. The second limiting protrusion 420 is opposite to the front end of the peripheral wall of the mounting opening 312, and a second detent 402 is formed by a gap between the second limiting protrusion and the front end of the peripheral wall of the mounting opening 312. In this embodiment, the first restraining ridge 410 is lower than the second restraining ridge 420, which allows the electrolytic deoxygenator device 200 to be tilted downward from front to back.

The back part of the electrolytic oxygen removing device 200 is clamped in the first clamping position 401, and the front part of the electrolytic oxygen removing device 200 is clamped in the second clamping position 402. The two clamping positions are utilized to respectively position the front part and the rear part of the electrolytic oxygen removal device 200, which is beneficial to improving the stability of the assembly structure between the electrolytic oxygen removal device 200 and the limiting component.

In the drawings, the terms "front", "rear", "horizontal", "up", "down", and the like, which indicate directions or positional relationships, are based on the directions or positional relationships shown in the drawings, and are only for convenience of description, but do not indicate or imply that the described devices or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Of course, in alternative embodiments, other mounting means can be selected to secure the electrolytic deoxygenator device 200 so long as it is capable of being disposed at the recess 114a in an inclined manner and closing the mounting opening 312.

Fig. 5 is a schematic structural view of an electrolytic oxygen removing device 200 of a refrigerator 10 according to an embodiment of the present invention, and fig. 6 is a schematic exploded view of the electrolytic oxygen removing device 200 of the refrigerator 10 shown in fig. 5.

In some alternative embodiments, electrolytic oxygen removal device 200 includes a housing 210, a cathode plate 220, and an anode plate 230. The housing 210 is a flat rectangular parallelepiped, and has an opening 211 facing the mounting opening 312 on a wider side surface thereof.

The cathode plate 220 serves as a cathode electrode of the electrolytic oxygen removal device 200 for the reduction reaction of oxygen to occur. The cathode plate 220 is disposed at the opening 211 to define a reservoir chamber 214 for containing an electrolyte together with the housing 210 and to consume oxygen in the storage container 300 through an electrochemical reaction. For example, oxygen in the air may undergo a reduction reaction at the cathode plate 220, i.e.: o is ₂ +2H ₂ O+4e ^- →4OH ^- 。

The anode plate 230 serves as the anode electrode of the electrolytic oxygen removal device 200 for the oxidation reaction to occur. An anode plate 230 is disposed within the reservoir 214 and is configured to provide a reactant, such as electrons, to the cathode plate 220 via an electrochemical reaction. OH generated from the cathode plate 220 ^- An oxidation reaction may occur at the anode plate 230 and oxygen is generated, i.e.: 4OH ^- →O ₂ +2H ₂ O+4e ^- . The oxygen may be vented through a vent 218 in the housing 210.

The wider side of the housing 210 is the top surface of the housing 210. The distance between the front end of the opening 211 and the front end of the top surface of the case 210 is greater than a preset threshold value to immerse the cathode plate 220 in the electrolyte when the duration of the electrochemical reaction is within a preset range. The time length of the electrochemical reaction is an accumulated time length of the electrochemical reaction obtained by starting timing with a state where the liquid storage chamber 214 is filled with the electrolyte as an initial state. Along with the progress of electrochemical reaction, the electrolyte in the stock solution chamber 214 can constantly reduce, when the electrolyte reduces to a certain extent, can take place the negative plate 220 and partially break away from the electrolyte or even break away from the condition of electrolyte completely, and this can lead to electrochemical reaction unable normal clear, and can lead to the negative plate 220 to take place to leak gas, and then leads to electrolysis deaerating plant 200 to become invalid.

Based on the above structure, because the electrolytic oxygen removal device 200 is obliquely arranged, the opening 211 is formed in the top surface of the shell 210 of the electrolytic oxygen removal device 200, and the distance between the front end of the opening 211 and the front end of the top surface of the shell 210 is set to be greater than the preset threshold, so that the cathode plate 220 can be always immersed in the electrolyte when the duration of the electrochemical reaction is within the preset range, and therefore, based on the scheme of the embodiment, the performance weakening caused by the oblique arrangement of the electrolytic oxygen removal device 200 can be reduced or avoided. The preset range may be set according to the maximum operating time of the electrolytic oxygen removing device 200 for removing oxygen from the storage space, and may be, for example, a multiple of the maximum operating time.

In some alternative embodiments, fluid refill port 216 is formed in a front side of housing 210 for allowing fluid to flow therethrough into reservoir 214 to refill reservoir 214. For example, a fluid infusion tube may be connected to the fluid infusion port 216 and extend forward to facilitate fluid infusion by a user. In some further embodiments, the refrigerator 10 may further include a fluid level sensor disposed within the fluid reservoir 214 for detecting a fluid level within the fluid reservoir 214, the refrigerator 10 being configured to provide a notification signal to indicate to a user to replenish fluid when the fluid level within the fluid reservoir 214 is below a predetermined threshold.

Of course, in other embodiments, the refrigerator 10 may further include a fluid replacement container for replacing the fluid in the fluid storage cavity 214, and the refrigerator 10 may automatically replace the fluid in the fluid storage cavity 214 by using the fluid replacement container. For example, the fluid replacement container may be in communication with the fluid replacement port 216, and a solenoid valve may be disposed at the fluid replacement port 216 for opening and closing the fluid replacement port 216, and when the fluid level in the fluid storage chamber 214 is lower than a preset threshold, the solenoid valve may be controlled to open the fluid replacement port 216 to allow the fluid in the fluid replacement container to flow into the fluid storage chamber 214.

The front side of the casing 210 is further opened with an exhaust port 218 spaced apart from the fluid infusion port 216 for discharging oxygen generated during the electrochemical reaction of the anode plate 230. The vented oxygen may follow the flow of the return air or may be directed out of the refrigerator 10 by the vent tube 260.

In some alternative embodiments, the storage container 300 is a drawer having a cylinder body 310 and a drawer body 320 drawably disposed at the cylinder body 310 in a front-to-rear direction. And an air flow channel 301 for passing air flow is arranged between the inner wall of the cylinder body 310 and the circumferential wall of the drawer body 320. The mounting port 312 is opened in the cylinder 310. So configured, the air in the drawer body 320 may flow through the air flow channel 301 and to the mounting port 312 so as to participate in the electrochemical reaction as a reactant of the cathode plate 220.

In some further embodiments, the refrigerator 10 further includes a blower 500 disposed on an inner wall of the cylinder 310 and within the airflow channel 301 for promoting airflow through or towards the mounting opening 312. Under the action of the fan 500, the air in the storage container 300 is rapidly stirred and flows through or towards the mounting opening 312 along the airflow channel 301 (the airflow flowing direction is shown in fig. 2), so that the oxygen removing efficiency of the electrolytic oxygen removing device 200 can be improved, and the uniformity of the air in the storage container 300 can be ensured. The blower 500 is used for promoting the formation of the internal circulation airflow in the storage container 300, and the type of the internal circulation airflow can be arbitrarily selected according to actual needs, and for example, the internal circulation airflow can be a micro centrifugal blower 500 or a micro axial flow blower 500.

In some embodiments, the refrigerator 10 may further have a mounting cavity 118 located at the rear side of the storage compartment 112, and the mounting cavity 118 communicates with the storage compartment 112 through a supply air outlet 116 and a return air outlet 117. And an evaporator 600 and a blowing fan 700 may be disposed in the installation cavity 118, wherein the evaporator 600 is configured to exchange heat with an air flow passing therethrough. The blower fan 700 is configured to circulate air flowing through the evaporator 600, the air supply opening 116, the storage compartment 112, the air return opening 117, and the evaporator 600 in sequence, so as to provide heat exchange air flow to the storage compartment 112 to adjust the temperature of the storage compartment 112, and the air flow direction is as shown in fig. 2.

In some embodiments, the electrolytic deoxygenator device 200 may further include a separator 240 and a securing assembly 250.

The separator 240 is disposed in the liquid storage cavity 214 and located between the cathode plate 220 and the anode plate 230 for separating the cathode plate 220 and the anode plate 230 and preventing the electrolytic oxygen removing device 200 from short circuit. Specifically, the separator 240 is formed with a plurality of protrusions 242 on a side facing the anode plate 230, the protrusions 242 abut against the anode plate 230, and the cathode plate 220 abuts against a side of the separator 240 facing away from the protrusions 242 to form a predetermined gap between the cathode plate 220 and the anode plate 230, thereby separating the cathode plate 220 from the anode plate 230.

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

The metal frame 252 abuts the outside of the cathode plate 220. The metal frame 252 directly contacts the cathode plate 220 to press the cathode plate 220, and a cathode power supply terminal 252b of the cathode plate 220 may be further provided on the metal frame 252 to be connected to an external power source. The anode plate 230 may be provided with an anode power supply terminal 232 to be connected to an external power source.

The support 254 is formed with a socket. When the standing part 252aa of the metal frame 252 enters the insertion groove of the support 254, the metal frame 252 may be fixed and positioned by the support 254, so that the metal frame 252 presses the cathode plate 220.

In the refrigerator 10 of the above embodiment, the electrolytic oxygen removal device 200 is used to consume oxygen in the storage compartment 112, and the electrolytic oxygen removal device 200 has the advantage of small volume, so that the refrigerator 10 does not occupy too much space, and the refrigerator 10 has a low-oxygen fresh-keeping function and can ensure the effective volume of the refrigerator 10. By providing the electrolytic oxygen removal device 200 at an incline to the bottom of the storage compartment 112, the appearance and configuration of the refrigerator 10 in the lateral and depth directions can be further prevented from being affected by the installation of the electrolytic oxygen removal device 200.
