[0042] Figure 1 is a schematic block diagram of a refrigerator 1 according to an embodiment of the present invention.

[0043] The refrigerator 1 includes an electrolytic deoxygenation device 20, a liquid storage device 10, a processor 81 and a memory 82, wherein the electrolytic deoxygenation device 20 is used to consume oxygen in the storage space of the refrigerator 1 through an electrochemical reaction under the action of an electrolysis voltage, and the liquid storage device 10 is used to replenish liquid to the reaction container of the electrolytic deoxygenation device 20.

[0044] The processor 81 and the memory 82 can form a control device 80 of the refrigerator 1. For example, the control device 80 can be a main control chip. The memory 82 stores a machine executable program 821, which is used to implement the control method of the refrigerator 1 of any of the following embodiments when the machine executable program 821 is executed by the processor 81. The processor 81 can be a central processing unit (CPU), or a digital processing unit (DSP), etc. The memory 82 is used to store the program executed by the processor 81. The memory 82 can be any medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer, but is not limited to this. The memory 82 can also be a combination of various memories. Since the machine executable program 821 implements the various processes of the following method embodiments when it is executed by the processor 81, and can achieve the same technical effect, it will not be repeated here to avoid repetition.

[0045] Figure 2 is a schematic diagram of a control method of a refrigerator 1 according to an embodiment of the present invention.

[0046] The control method may generally include the following steps:

[0047] Step S202, detecting the liquid storage amount of the liquid storage device 10. The liquid storage amount of the liquid storage device 10 can be characterized by liquid level or volume. The liquid storage amount of the liquid storage device 10 is used to measure whether the liquid supply of the electrolytic deoxygenation device 20 is sufficient.

[0048] Step S204: When the liquid storage volume is higher than the preset value, the electrolytic deoxidation device 20 is allowed to start. The preset value can be set according to the amount of liquid consumed by the electrochemical reaction of the electrolytic deoxidation device 20 within a set time period, and the average value is taken through multiple measurements as the preset value.

[0049] Allowing the electrolytic deoxidizer 20 to start is relative to "not allowing the electrolytic deoxidizer 20 to start". When the electrolytic deoxidizer 20 is allowed to start, the electrolytic deoxidizer 20 can be started in a controlled manner according to the actual deoxygenation demand. When the electrolytic deoxidizer 20 is not allowed to start, the electrolytic deoxidizer 20 cannot be started even if the storage space has a deoxygenation demand.

[0050] Using the above method, since the liquid storage device 10 can be used to replenish liquid to the reaction container of the electrolytic deoxidation device 20, and when the liquid storage amount of the liquid storage device 10 is higher than the preset value, the electrolytic deoxidation device 20 is allowed to be started, thereby ensuring that the electrolytic deoxidation device 20 is started when the liquid supply is sufficient. Therefore, based on the solution of the present invention, the continuity and effectiveness of the deoxygenation process of the refrigerator 1 can be guaranteed.

[0051] The liquid storage device 10 includes a first liquid storage container 110 and a second liquid storage container 210. The first liquid storage container 110 is communicated with the reaction container of the electrolytic deoxidation device 20 and is used to replenish liquid to the reaction container. The second liquid storage container 210 is communicated with the first liquid storage container 110 and is used to replenish liquid to the first liquid storage container 110. That is, the liquid in the second liquid storage container 210 can first flow into the first liquid storage container 110 and then flow into the reaction container.

[0052] The step of detecting the liquid storage amount of the liquid storage device 10 includes: detecting the liquid level of the second liquid storage container 210, and determining the liquid storage amount of the liquid storage device 10 according to the liquid level of the second liquid storage container 210. For example, a liquid level sensor is provided in the second liquid storage container 210 to detect the liquid level of the second liquid storage container 210.

[0053] For example, the liquid storage volume of the liquid storage device 10 is characterized by the liquid level, and the preset value is also characterized by the liquid level. By comparing whether the liquid level of the second liquid storage container 210 is higher than the preset value, it can be determined whether the liquid storage volume of the liquid storage device 10 is higher than the requirement.

[0054] By detecting the liquid level of the second liquid storage container 210 of the liquid storage device 10, it can be determined whether the liquid storage amount of the liquid storage device 10 meets the requirements, and the control process is simple.

[0055] The second liquid storage container 210 is provided with a liquid filling port 602 b for liquid replenishment. The user can inject liquid from the external environment into the second liquid storage container 210 through the liquid filling port 602 b to complete liquid replenishment of the second liquid storage container 210 .

[0056] In some embodiments, after the step of detecting the liquid storage amount of the liquid storage device 10, the control method further includes: when the liquid storage amount is not higher than a preset value, outputting a liquid replenishment prompt signal to prompt the user to replenish liquid to the liquid filling port 602b of the second liquid storage container 210.

[0057] Using the above method, it is possible to automatically evaluate whether the liquid storage amount of the liquid storage device 10 meets the requirements, and to urge the user to replenish liquid to the second liquid storage container 210 of the liquid storage device 10 in time, thereby ensuring the normal operation of the electrolytic deoxygenation device 20 and ensuring the continuity and effectiveness of the deoxygenation process.

[0058] Using two liquid storage containers as the liquid replenishment tanks of the electrolytic deoxygenator 20 can, to a certain extent, increase the liquid supply of the electrolytic deoxygenator 20. Separating the liquid storage device 10 from the electrolytic deoxygenator 20 and independently arranging it can avoid directly replenishing the liquid to the electrolytic deoxygenator 20, simplifying the liquid replenishment process, and also avoiding the liquid storage device 10 occupying too much low-oxygen fresh-keeping space, thereby improving the utilization rate of the low-oxygen fresh-keeping space.

[0059] In some embodiments, a reset switch is provided on the power supply circuit where the electrolytic deoxygenation device 20 is located. While outputting the fluid replenishment prompt signal, the control method may further include: controlling the reset switch to switch to an open circuit state so that the power supply circuit is disconnected at the reset switch.

[0060] For example, a switch element may be provided on the power supply circuit, and the electrolysis voltage of the electrolytic deoxygenation device 20 may be cut off or turned on by controlling the switch element to be opened or closed. A reset switch may be provided in series with the electrolytic deoxygenation device 20 in the power supply circuit. When the reset switch is in an open circuit state, even if the switch element is closed, the power supply circuit is still in an open circuit state, and the electrolytic deoxygenation device 20 cannot be powered on and started.

[0061] By using the above method, combined with regulating the state of the reset switch on the power supply circuit, it is possible to prevent the electrolytic deoxygenation device 20 from being started "without permission" when the liquid supply is insufficient. Therefore, the solution of this embodiment can utilize a concise and ingenious control logic to improve the operating reliability of the electrolytic deoxygenation device 20. The electrolytic deoxygenation device 20 will not be powered on and started due to the connection of the electrolysis voltage, thereby avoiding waste of electric energy or safety accidents.

[0062] After controlling the reset switch to switch to the open circuit state, the control method may further include: detecting the liquid storage amount of the liquid storage device 10 again, and when the liquid storage amount is higher than a preset value, controlling the reset switch to switch to the short circuit state, so that the power supply circuit is connected at the reset switch, thereby allowing the electrolytic deoxidation device 20 to start. That is, the step of allowing the electrolytic deoxidation device 20 to start is to switch the reset switch to the short circuit state, or keep the short circuit state.

[0063] That is to say, by adjusting the state of the reset switch, the start-up of the electrolytic deoxygenation device 20 can be allowed or not. When the reset switch is in a short-circuit state, the on-off of the power supply circuit is controlled only by the switch element, and the switch element can be data-connected with the control device 80 of the refrigerator 1, so that the on-off state of the switch element can be controlled by the control device 80. For example, when the storage space has a deoxygenation demand, the control device 80 controls the switch element to close, thereby connecting the entire power supply circuit, so that the electrolytic deoxygenation device 20 is connected to the electrolysis voltage and starts the electrochemical reaction. When the reset switch is in an open-circuit state, the on-off of the power supply circuit is no longer controlled only by the switch element. Even if the switch element is closed, the entire power supply circuit cannot be connected, and the electrolytic deoxygenation device 20 cannot be connected to the electrolysis voltage.

[0064] In some optional embodiments, after starting the electrolytic deoxygenation device 20, the control method may further include: obtaining the liquid level change values ​​of the first liquid storage container 110 and the second liquid storage container 210, and determining the working state of the liquid storage device 10 and / or the deoxygenation efficiency of the electrolytic deoxygenation device 20 according to the liquid level change values ​​of the first liquid storage container 110 and the second liquid storage container 210.

[0065] Since the second liquid storage container 210 is connected to the first liquid storage container 110, and the first liquid storage container 110 is connected to the reaction container, the working state of the liquid storage device 10 and / or the deoxygenation efficiency of the electrolytic deoxygenation device 20 can be determined by analyzing the liquid level change values ​​of the first liquid storage container 110 and the second liquid storage container 210, so as to judge whether the liquid storage device 10 and the electrolytic deoxygenation device 20 are operating normally. The method is simple and effective.

[0066] For example, within a set time period, the electrolyte consumption of the electrolytic deoxidation device 20 can be determined by analyzing the liquid level change values ​​of the first liquid storage container 110 and the second liquid storage container 210. Since the electrolytic deoxidation device 20 has a fixed value of oxygen consumption theoretical value while consuming a unit volume of electrolyte, the actual oxygen consumption of the electrolytic deoxidation device 20 can be determined based on the obtained electrolyte consumption and oxygen consumption theoretical value, and then the actual oxygen consumption rate can be determined. The oxygen consumption rate is the deoxygenation efficiency of the electrolytic deoxidation device 20.

[0067] For another example, within a set time period, by analyzing the liquid level change values ​​of the first liquid storage container 110 and the second liquid storage container 210, if it is found that the liquid level change values ​​of the two liquid storage containers do not match, it can be determined that the liquid storage device 10 is in an abnormal state and needs to be repaired. For example, if the liquid level change value of the first liquid storage container 110 is greater than a preset first change threshold, and the liquid level change value of the second liquid storage container 210 is zero or less than a preset second change threshold, it can be determined that the liquid level change values ​​of the two liquid storage containers do not match.

[0068] In some optional embodiments, before the step of detecting the liquid storage amount of the liquid storage device 10, the control method may further include: determining that the liquid storage device 10 is in a preset working position. When the liquid storage device 10 is in the preset working position, normal communication between the first liquid storage container 110 and the reaction container can be ensured.

[0069] The refrigerator 1 may further include a pressure sensor installed below the liquid storage device 10. The step of determining that the liquid storage device 10 is in a preset working position includes: obtaining a detection value of the pressure sensor installed below the liquid storage device 10, and determining that the liquid storage device 10 is in the working position when the detection value of the pressure sensor is greater than a preset detection threshold. The detection threshold can be set according to the weight of the liquid storage device 10 itself (excluding liquid).

[0070] When the liquid storage device 10 is not in the working position, the user may move the liquid storage device 10 out of the refrigerator 1 for liquid replenishment. Since the amount of liquid stored during the liquid replenishment process is constantly changing, the above method is used to perform the step of detecting the liquid storage amount of the liquid storage device 10 when it is determined that the liquid storage device 10 is in the working position. This can improve the validity of the detection result.

[0071] Figure 3 1 is a control flow chart of a refrigerator 1 according to an embodiment of the present invention. The control flow generally may include the following steps:

[0072] Step S302 , obtaining a detection value of a pressure sensor installed below the liquid storage device 10 .

[0073] Step S304: when the detection value of the pressure sensor is greater than a preset detection threshold, it is determined that the liquid storage device 10 is in the working position.

[0074] Step S306 , detecting the liquid level of the second liquid storage container 210 .

[0075] Step S308 , determining the liquid storage amount of the liquid storage device 10 according to the liquid level of the second liquid storage container 210 .

[0076] Step S310, determining whether the liquid storage amount of the liquid storage device 10 is higher than a preset value, if so, executing step S312, if not, executing step S314.

[0077] Step S312, allowing the electrolytic deoxygenation device 20 to start.

[0078] Step S314 , outputting a liquid replenishment prompting signal to prompt the user to replenish liquid into the liquid filling port 602 b of the second liquid storage container 210 .

[0079] Step S316, controlling the reset switch to switch to an off-circuit state, so that the power supply circuit is disconnected at the reset switch.

[0080] Step S318, detecting the liquid storage amount of the liquid storage device 10 again;

[0081] Step S320, when the liquid storage amount is higher than a preset value, the reset switch is controlled to switch to a short circuit state so that the power supply circuit is connected at the reset switch, thereby allowing the electrolytic deoxygenation device 20 to start.

[0082] Step S322, obtaining a start signal of the electrolytic deoxygenation device 20. That is, after the electrolytic deoxygenation device 20 is started, the following steps S324-S326 are executed.

[0083] Step S324 , obtaining the liquid level change values ​​of the first liquid storage container 110 and the second liquid storage container 210 .

[0084] Step S326 , determining the working state of the liquid storage device 10 and / or the deoxygenation efficiency of the electrolytic deoxygenation device 20 according to the liquid level change values ​​of the first liquid storage container 110 and the second liquid storage container 210 .

[0085] The refrigerator 1 and the control method thereof of the present invention can utilize the liquid storage device 10 to replenish liquid to the reaction container of the electrolytic deoxidation device 20, and when the liquid storage amount of the liquid storage device 10 is higher than a preset value, the electrolytic deoxidation device 20 is allowed to be started, thereby ensuring that the electrolytic deoxidation device 20 is started when the liquid supply is sufficient. Therefore, based on the solution of the present invention, the continuity and effectiveness of the deoxygenation process of the refrigerator 1 can be guaranteed.

[0086] In some optional embodiments, the liquid storage device 10 can be pulled out and arranged in the refrigerator 1 to facilitate the user to replenish liquid and facilitate the user's operation.

[0087] In other optional embodiments, the first liquid storage container 110 and the second liquid storage container 210 of the liquid storage device 10 are provided with antibacterial and anti-mildew modules to prevent the generation of microorganisms inside the liquid storage device 10, thereby extending the service life of the electrolytic deoxidation device 20. For example, the antibacterial and anti-mildew module can be a uniformly distributed antibacterial and anti-mildew agent, which is non-toxic and harmless.

[0088] Figure 4 is a schematic structural diagram of a liquid storage device 10 of a refrigerator 1 according to an embodiment of the present invention, Figure 5 yes Figure 4 An exploded view of the liquid storage device 10 of the refrigerator 1 is shown.

[0089] In some optional embodiments, the liquid storage device 10 has a box body 150 and a first liquid storage part 100 and a second liquid storage part 200 disposed in the box body 150. The interior of the box body 150 forms an installation space for the first liquid storage part 100 and the second liquid storage part 200. Integrating the first liquid storage part 100 and the second liquid storage part 200 into the box body 150 respectively can improve the structural integrity of the liquid storage device 10, and facilitate the user to perform a pulling action on the liquid storage device 10 as a whole. In order to facilitate the user to replenish the second liquid storage container 210, a liquid injection port (not shown) located above the liquid filling port 602b can be opened on the box body 150, and a reversible flip cover 151 is provided at the liquid injection port, and the user opens and closes the liquid injection port by flipping the flip cover 150.

[0090] Figure 6 is a schematic structural diagram of a liquid storage device 10 according to an embodiment of the present invention. Figure 7 yes Figure 6 A schematic top view of the liquid storage device 10 is shown. Figure 8 yes Figure 6 The schematic front view of the liquid storage device 10 shown in FIG. Figure 8 The liquid storage device 10 of this embodiment has a filtering and recycling function, which can separate and recycle specific material components in the gas for utilization.

[0091] The liquid storage device 10 may generally include a first liquid storage portion 100 and a second liquid storage portion 200 .

[0092] The first liquid storage part 100 has a first filter housing 120 and a first filter element 130. The first filter housing 120 and the first filter element 130 form a first filter mechanism. The first filter housing 120 is provided with a first air inlet 121 and a first air outlet 122. The first filter element 130 is disposed in the first filter housing 120 and is used to dissolve specific material components in the gas passing through the first air inlet 121 in the first filter housing 120 to achieve filtering and recovery. The first air outlet 122 is used to discharge the filtered gas.

[0093] The first filter housing 120 can also be used to store liquid, such as electrolyte or water containing specific components. The specific substance components in the gas from the external environment of the liquid storage device 10 are dissolved in the first filter housing 120, which means that they are dissolved in the liquid stored in the first filter housing 120.

[0094] The second liquid storage part 200 has a second filter housing 220 and a second filter element 230. The second filter housing 220 and the second filter element 230 form a second filter mechanism. The second filter housing 220 is provided with a second air inlet 221 and a second air outlet 222. The second air inlet 221 is in communication with the first air outlet 122. The second filter element 230 is disposed in the second filter housing 220 and is used to dissolve specific material components in the gas passing from the first air outlet 122 into the second air inlet 221 in the second filter housing 220, so as to achieve re-filtration and recovery. The second air outlet 222 is used to discharge the gas after re-filtration.

[0095] The second filter housing 220 can also be used to store liquid, such as electrolyte or water containing specific components. The specific substance components in the gas from the external environment of the liquid storage device 10 are dissolved in the second filter housing 220, which means that they are dissolved in the liquid stored in the second filter housing 220.

[0096] In this embodiment, the specific material component is a water-soluble material. In some optional embodiments, the liquid components stored in the first filter housing 120 and the second filter housing 220 can be adjusted according to the physical and chemical properties of the specific material component to be separated.

[0097] The liquid storage device 10 of this embodiment can utilize the first filter element 130 and the first filter shell 120 to dissolve specific material components in the gas passing through the first air inlet 121 in the first filter shell 120 to achieve filtering and recovery, and can utilize the second filter element 230 and the second filter shell 220 to dissolve specific material components in the gas passing through the second air inlet 221 from the first air outlet 122 in the second filter shell 220 to achieve re-filtration and recovery. Therefore, this embodiment provides a liquid storage device 10 with filtering and recovery function, which can separate and recycle specific material components in the gas, thereby reducing or avoiding pollution caused by gas emissions and improving resource utilization efficiency.

[0098] By organically combining the first liquid storage part 100 and the second liquid storage part 200, the specific material components in the gas passing into the first air inlet 121 are filtered and recovered multiple times, which is beneficial to improving the filtering efficiency and recovery efficiency of the liquid storage device 10, and can further reduce exhaust gas emission pollution and resource waste.

[0099] It is worth noting that the number of the second filter parts can be set to one or more according to actual needs to adjust the number of filtration and recovery. This embodiment is only exemplified for the case where the number of the second filter part is one, but it should not be regarded as limiting the number of the second filter parts.

[0100] In some optional embodiments, the first liquid storage portion 100 further includes a first liquid storage container 110 , and the first filter housing 120 is in communication with the first liquid storage container 110 to allow specific material components dissolved in the first filter housing 120 to enter the first liquid storage container 110 .

[0101] The second liquid storage part 200 further includes a second liquid storage container 210 . The second filter housing 220 is in communication with the second liquid storage container 210 to allow specific material components dissolved in the second filter housing 220 to enter the second liquid storage container 210 .

[0102] Since each filter housing has a corresponding liquid storage container in communication therewith, the specific material components retained in each filter housing can flow into the corresponding liquid storage container for reuse.

[0103] As for the communication mode between each filter housing and the corresponding liquid storage container, for example, each filter housing can be inserted into the corresponding liquid storage container. Each liquid storage container can be roughly rectangular, and each filter housing can be inserted into the corresponding liquid storage container as an inner sleeve.

[0104] Specifically, the first filter housing 120 is inserted into the first liquid storage container 110, and a first liquid outlet 123 is provided at the bottom of the first filter housing 120 to communicate with the first liquid storage container 110, so as to allow the liquid in the first filter housing 120 to flow into the first liquid storage container 110. The second filter housing 220 is inserted into the second liquid storage container 210, and a second liquid outlet 223 is provided at the bottom of the second filter housing 220 to communicate with the second liquid storage container 210, so as to allow the liquid in the second filter housing 220 to flow into the second liquid storage container 210.

[0105] Since each filter housing is connected to the corresponding liquid storage container through the liquid outlet hole at the bottom, the liquid in each filter housing can flow downward through the liquid outlet hole and return to the liquid storage container by its own gravity, which makes the recovery process of the liquid storage device 10 simple and effective.

[0106] The above examples of connection methods are merely illustrative and can be easily expanded upon by those skilled in the art, so they are not listed one by one here.

[0107] In some optional embodiments, the second liquid storage container 210 is connected to the first liquid storage container 110. And the first liquid storage container 110 is provided with a liquid supply port 114 connected to the external environment for replenishing liquid to the external environment. That is, the liquid storage device 10 of this embodiment has both a filtering and recycling function and a liquid replenishing function while storing liquid, which facilitates the reuse of specific material components obtained by filtering and recycling. For example, the specific material components in the first liquid storage container 110 can be reused by certain devices in the external environment after flowing out from the liquid supply port 114. The specific material components entering the second liquid storage container 210 can first enter the first liquid storage container 110, and then flow out through the liquid supply port 114 to be reused by certain devices in the external environment.

[0108] Fig. 9 yes Figure 7 A schematic side view of a portion of the structure of the liquid storage device 10 is shown. Fig.10 yes Figure 7 The schematic structural diagram of part of the structure of the liquid storage device 10 is shown. Fig. 9 and Fig.10 All are perspective drawings. Fig.10 The perspective parts are shown with dashed lines.

[0109] In some optional embodiments, the second liquid storage container 210 and the first liquid storage container 110 have a common wall, and a portion of the bottom wall 211 of the second liquid storage container 210 is concave (i.e., concave upward) to form a common first wall 111 and a second wall 112. That is, the common wall includes the first wall 111 and the second wall 112. The first wall 111 serves as a side wall of the first liquid storage container 110, which can extend along a vertical plane. The second wall 112 serves as a portion of the top wall of the first liquid storage container 110, which can extend along a horizontal plane. If the bottom wall 211 of the second liquid storage container 210 is not concave, the second liquid storage container 210 is roughly in the shape of a cuboid. By making a portion of the bottom wall 211 of the second liquid storage container 210 concave and forming the common first wall 111 and the second wall 112, a portion of the first liquid storage container 110 can be located below the second liquid storage container 210.

[0110] The second wall 112 is provided with an opening 112a to connect the second liquid storage container 210 with the first liquid storage container 110. This can cause the liquid in the second liquid storage container 210 to flow down to the first liquid storage container 110 through the opening 112a by its own gravity. The liquid replenishment process of this embodiment does not require an external pump drive and does not generate noise.

[0111] In some optional embodiments, the first air inlet 121 and the first air outlet 122 are respectively located on the third wall 113 of the first liquid storage container 110, and the third wall 113 is another part of the top wall of the first liquid storage container 110, extending horizontally outward from the second wall 112 in a direction away from the second liquid storage container 210. The second wall 112 and the third wall 113 of this embodiment are connected to form a horizontal plane to serve as the top wall of the first liquid storage container 110. The third wall 113 is a non-shared wall, and the second liquid storage container 210 is not arranged above it, which is convenient for opening the first air inlet 121 and the first air outlet 122.

[0112] The second air inlet 221 and the second air outlet 222 are respectively located on the top wall of the second liquid storage container 210 .

[0113] In use, the liquid level in the second liquid storage container 210 is higher than the liquid level in the first liquid storage container 110 .

[0114] In some optional embodiments, the second liquid storage container 210 and the first liquid storage container 110 can be transformed from the above-mentioned integrated configuration to a separate independent configuration. In this case, a liquid discharge port 216 is provided on the second liquid storage container 210, and a liquid input port 116 is provided on the first liquid storage container 110. By connecting the liquid discharge port 216 with the liquid input port 116, the two liquid storage containers can be communicated.

[0115] Since the two filter mechanisms have the same structure, only the first filter mechanism is taken as an example to introduce its structure. Fig.11 yes Figure 7 The schematic structural diagram of the first filtering mechanism of the liquid storage device 10 is shown. Fig.12 yes Fig.11 A schematic exploded view of the first filtering mechanism of the liquid storage device 10 is shown.

[0116] The first filter element 130 and the second filter element 230 are air guide tubes, respectively, and extend downward from the first air inlet hole 121 and the second air inlet hole 221 to the bottom section in the first filter housing 120 and the bottom section in the second filter housing 220, respectively. For example, the first filter element 130 can be named as the first air guide tube, and the second filter element 230 can be named as the second air guide tube. The first air guide tube is inserted downward from the first air inlet hole 121 into the first filter housing 120 and extends to the bottom section in the first filter housing 120. The second air guide tube is inserted downward from the second air inlet hole 221 into the second filter housing 220 and extends to the bottom section in the second filter housing 220.

[0117] By extending the two air ducts to the bottom sections of the corresponding filter housings respectively, the gas flowing through the air ducts can be guided to the bottom sections of the corresponding filter housings, thereby extending the flow path of the gas in the filter housing. The gas flowing out of the air ducts can fully contact the liquid in the filter housing during the rising process, so that specific material components in the gas can be more fully dissolved in the filter housing. This enables the liquid storage device 10 to achieve better filtering and purification effects with a sophisticated and simple structure.

[0118] The air guide tube of this embodiment can be a straight tube, both ends of which are openings 112a to facilitate the inflow or outflow of gas. It has a simple structure and has a better air guide effect.

[0119] In some optional embodiments, the shape of the air guide tube can be changed to a vertical hook-shaped tube, and it has a straight tube section and a curved tube section formed by bending and extending upward from the end of the straight tube section. The end of the curved tube section is slightly higher than the end of the straight tube section, and is used to guide the gas flowing through it upward.

[0120] That is to say, the air guide tube of this embodiment can be in the shape of a vertical hook, the straight tube section is similar to an umbrella pole, and the curved tube section is similar to an umbrella handle connected to the end of the umbrella pole. The curved tube end is bent and extended upward from the end of the straight tube section, which can guide the gas flowing out of the air guide tube to flow upward, thereby making the movement direction of the gas clearer. The end of the curved tube section is slightly higher than the end of the straight tube section, which means that the end of the curved tube section is still in the bottom section of the filter housing, which will not significantly shorten the flow path of the gas during the dissolution process.

[0121] The air guide tube and the filter housing cooperate with each other to realize gas filtration using water, which can avoid the use of lossy filter materials and eliminate the need to replace the filter materials, thereby helping to save costs.

[0122] In some optional embodiments, each filter housing may be integrally formed. In other optional embodiments, the filter housing may be formed by connecting a plurality of different components. For example, each filter housing may include a first bin body 501 having a top opening 112a and a first bin cover 502 that closes the top opening 112a of the first bin body 501. The air inlet and the air outlet are located on the first bin cover 502 at intervals from each other. The first bin body 501 may be in the shape of a straight tube, and its diameter is greater than the diameter of the air duct. The top end of the first bin body 501 is in the shape of an opening 112a, and is sealed and connected to the first bin cover 502. The bottom end of the first bin body 501 is closed, and the above-mentioned liquid outlet is provided thereon. There may be at least one liquid outlet.

[0123] The air inlet, the air duct, and the air outlet are covered by the first housing 501 to form a sleeve structure. The bottom of the air duct is higher than the bottom of the first housing 501 to prevent the gas flowing out of the air duct from escaping from the first housing 501.

[0124] In some optional embodiments, the first liquid storage container 110 and the second liquid storage container 210 can be integrally formed, which is conducive to improving the sealing effect of the liquid storage container and preventing leakage. In other optional embodiments, the second liquid storage container 210 can be transformed into a plurality of different parts connected. For example, the second liquid storage container 210 may include a second warehouse body 601 with a top opening 112a and a second warehouse cover 602 that closes the top opening 112a of the second warehouse body 601. The second warehouse body 601 can be a rectangular water tank without a cover, and its volume is greater than the volume of the first warehouse body 501.

[0125] Fig.13 yes Figure 8 The schematic structural diagram of the second compartment cover 602 of the second liquid storage container 210 of the liquid storage device 10 is shown. Fig.13 (a) is a stereogram, Fig.13 (b) Main view, Fig.13 (c) is a top view.

[0126] The second bin cover 602 is provided with a mounting opening 602a. The hole wall of the mounting opening 602a extends upward to form a hollow cylindrical external thread interface 602e. Since the external thread interface 602e is formed by extending upward from the hole wall of the mounting opening 602a, the upper edge of the external thread interface 602e is higher than the upper surface of the second bin cover 602 and higher than the upper edge of the liquid adding groove 602c described below. This can control the highest liquid level during the liquid adding process to be below the upper edge of the external thread interface 602e.

[0127] The first bin cover 502 has a closed cover plate 502a located above the first bin body 501 and an annular internal thread interface 502b extending downward from the outer periphery of the closed cover plate 502a. The closed cover plate 502a is used to cover the top opening 112a of the first bin body 501. The annular internal thread interface 502b is screwed with the external thread interface 602e, so that the first bin cover 502 is detachably connected to the second bin cover 602. That is, the annular internal thread interface 502b is used to connect the first bin cover 502 to the second bin cover 602.

[0128] The first storage body 501 extends downward from the lower surface of the closed cover plate 502a, passes through the external thread interface 602e, and is inserted into the liquid storage container.

[0129] By screwing the first bin cover 502 and the second bin cover 602 together to close the installation opening 602a, the installation and fixing process of the second filter mechanism can be simplified, and the installation can be completed in one step.

[0130] In some optional embodiments, a liquid adding port 602b may be provided on the second compartment cover 602, and its port wall extends downward to form a liquid adding groove 602c. Since the liquid adding groove 602c extends downward from the upper surface of the second compartment cover 602, and the external threaded interface 602e extends upward from the upper surface of the second compartment cover 602, when liquid is added to the second compartment body 601 from the liquid adding port 602b, even if the liquid adding process causes the second compartment body 601 to overflow, the liquid level during the overflow will not exceed the external threaded interface 602e.

[0131] A portion of the wall of the liquid adding tank 602c is tilted and extended downward, so that the bottom of the liquid adding tank 602c forms a tapered opening 112a. In other words, the water adding tank is an inclined through hole with a certain depth, which is convenient for the user to observe the liquid level when adding liquid. The tilted downward extending tank wall has a liquid level mark to indicate the liquid level during the liquid adding process. For example, the liquid level mark can be designed as a "maximum liquid level scale line" to indicate to the user that the liquid is full.

[0132] In some optional embodiments, the edge of the second compartment cover 602 has a protrusion 602d protruding outward for applying force. The user can apply force to the second compartment cover 602 by grabbing or other actions, thereby realizing the disassembly process between the second compartment cover 602 and the second compartment body 601.

[0133] An elastic sealing ring may be provided at the periphery of the closed portion between the second bin cover 602 and the second bin body 601 to facilitate sealing through the compression between the second bin cover 602 and the second bin body 601 to prevent water leakage in the second bin body 601 .

[0134] The first liquid storage container 110 is integrally formed. To realize the assembly of the first filter mechanism, a mounting opening 602a is also provided on the third wall 113 of the first liquid storage container 110. The shape of the mounting opening 602a is the same as the shape of the mounting opening 602a on the second compartment cover 602. The assembly method of the first filter mechanism relative to the mounting opening 602a is also the same as the assembly method of the second filter mechanism relative to the mounting opening 602a, which will not be described in detail here.

[0135] Fig.14 yes Figure 7 A schematic structural diagram of a liquid level switch 300 of a liquid storage device 10 is shown. Fig.15 yes Fig.14 A schematic exploded view of a liquid level switch 300 of a liquid storage device 10 is shown.

[0136] In some further embodiments, the liquid storage device 10 may further include a liquid level switch 300, which is disposed in the first liquid storage container 110 and has a switch body 310, which is used to open and close the opening 112a according to the movement of the liquid level in the first liquid storage container 110, so as to allow or prevent the liquid in the second liquid storage container 210 from flowing into the first liquid storage container 110 through the opening 112a. In other words, the liquid level switch 300 is used to control the opening and closing of the opening 112a. That is, the liquid level switch 300 serves as a gate of the infusion channel between the second liquid storage container 210 and the first liquid storage container 110, and plays the role of opening and closing the infusion channel. The switch body 310 of the liquid level switch 300 moves according to the liquid level of the first liquid storage container 110, so as to close or open the opening 112a, and the opening and closing process of the opening 112a does not require electrical control. Fig.14 (a) shows the state when the switch body 310 closes the opening 112a, Fig.14 (b) shows the state when the switch body 310 opens the opening 112a, and the arrow direction in the figure shows the rotation direction of the float 320.

[0137] The switch body 310 can rise when the liquid level in the first liquid storage container 110 rises and abuts against the lower periphery of the opening 112a to close the opening 112a, so that the liquid in the second liquid storage container 210 cannot pass through the opening 112a. It can also fall when the liquid level in the first liquid storage container 110 decreases, thereby deviating from and opening the opening 112a, so that the liquid in the second liquid storage container 210 can flow downward into the first liquid storage container 110 by gravity. Under the action of the liquid level switch 300, the liquid in the first liquid storage container 110 and the liquid in the second liquid storage container 210 cannot directly contact each other, and can maintain a certain height distance to prevent the migration of solution substances due to the confluence of the liquids and avoid contamination.

[0138] The liquid level switch 300 further includes a float 320, which is fixedly connected to the switch body 310 or is an integral part of the switch body 310, and is used to drive the switch body 310 to move by floating or sinking in the first liquid storage container 110. In other words, the switch body 310 is "driven" by the float 320, and the power required for the float 320 to move is determined by the buoyancy it receives in the first liquid storage container 110.

[0139] For example, a portion of the float 320 is immersed in liquid, so that the float 320 is subjected to the buoyancy of the liquid. When the liquid level in the first liquid storage container 110 changes, the buoyancy of the float 320 will also change, so that the combined force of the buoyancy and gravity on the float 320 will change. For example, when the liquid level in the first liquid storage container 110 decreases, the buoyancy of the float 320 will decrease. If the combined force of the buoyancy and gravity on the float 320 is directed downward, the float 320 will move downward. Otherwise, the float 320 will move upward. The float 320 can rise or fall in a vertical direction, or can rise or fall along a curve.

[0140] In some optional embodiments, the float 320 can be arranged to rotate around an axis. That is, the float 320 of this embodiment does not move up and down along a straight line, but rises or falls in a manner of rotating around an axis. With such a design, it is only necessary to pivotally connect the float 320 to a fixed axis, and there is no need to install a guide component with high dimensional accuracy. The float 320 has the advantages of delicate structure, simple assembly process, and good device reliability.

[0141] Since the float 320 can be rotatably arranged around the axis, the movement trajectory is clear and definite, which makes it easy for the float 320 and the switch body 310 of this embodiment to move along the clear and definite movement trajectory, thereby improving the reliability of the liquid level switch 300 and reducing or avoiding problems such as poor sealing caused by the free movement of the float 320.

[0142] The liquid level switch 300 may further include a rotating shaft 340 and a connecting member 330 .

[0143] The rotating shaft 340 is fixed to the first liquid storage container 110 . For example, the rotating shaft 340 can be fixed to the inner space of the first liquid storage container 110 and fixedly connected to the inner wall of the first liquid storage container 110 .

[0144] In some optional embodiments, the rotating shaft 340 can also be detachably fixed to the first liquid storage container 110, so that the height of the rotating shaft 340 can be adjusted according to actual needs, thereby adjusting the liquid level height in the first liquid storage container 110 to start the liquid replenishment.

[0145] The connecting member 330 is fixedly connected to the float 320 or is an integral part with the float 320, and is formed with an axial hole 341 for the rotation shaft 340 to be inserted therein and rotatably matched therewith so as to realize a rotatable connection. In other words, the connecting member 330 assembles the rotation shaft 340 and the float 320 into an organic whole, so that the float 320 can rotate around the rotation shaft 340.

[0146] By opening the shaft hole 341 on the connecting member 330 and making the rotating shaft 340 rotatably cooperate with the shaft hole 341 , the float 320 can be rotatably assembled to the rotating shaft 340 , which has an exquisite structure and a simple process.

[0147] The switch body 310 is in the shape of a rod. The connecting member 330 is also formed with an installation opening 602a for a part of the switch body 310 to be inserted therein for fixed assembly. In other words, a part of the switch body 310 is fixedly assembled with the connecting member 330, thereby indirectly achieving fixed connection with the float 320. For example, the part of the switch body 310 can be assembled with the installation opening 602a of the connecting member 330 by interference fit.

[0148] The rotating shaft 340 and the switch body 310 are respectively assembled to the connecting piece 330 which is fixedly connected to the float 320 or is an integral piece with the float 320, so as to form the liquid level switch 300, and the structural integrity is strong. The switch body 310 and the float 320 are located on the same side of the rotating shaft 340. The switch body 310 and the float 320 are on the same side, which means that the switch body 310 is located between the rotating shaft 340 and the float 320, which is the key to make the switch body 310 "move in the same direction" as the float 320 according to the liquid level height of the internal space of the first liquid storage container 110, and a larger "arm ratio" can be obtained.

[0149] In this embodiment, the central axis of the rotating shaft 340 extends in the horizontal direction and is perpendicular to the central longitudinal vertical symmetry plane of the float 320. For example, for the cylindrical float 320, when the two bottom surfaces 321 of the float 320 are arranged relatively to each other in the horizontal direction, the central longitudinal vertical symmetry plane of the float 320 is the longitudinal central cross section of the float 320 extending in the vertical direction. When the switch body 310 closes the liquid replenishing port 202, the central axis of the mounting hole 342 extends in the vertical direction and is parallel to the central longitudinal vertical center line of the float 320, wherein the central longitudinal vertical center line of the float 320 is the longitudinal center line of the longitudinal central cross section of the float 320 extending in the vertical direction. The directional words such as "horizontal" and "vertical" are all relative to the actual use state of the liquid level switch 300, and the longitudinal direction is roughly the vertical direction.

[0150] In some optional embodiments, the float 320 is in the shape of a hollow cylinder. The cylinder of the float 320 of this embodiment is a cavity structure, which can further enhance the buoyancy (the overall density is less than the liquid density). The central axis of the float 320 is parallel to the central axis of the shaft hole 341. The central axis of the float 320 is collinear with the centers of the two bottom surfaces 321. Since the central axis of the shaft hole 341 extends in the horizontal direction, the central axis of the float 320 also extends in the horizontal direction, and the two bottom surfaces 321 of the float 320 are arranged opposite to each other in the horizontal direction.

[0151] In some optional embodiments, the connecting member 330 is a cantilever, which is formed by obliquely extending outward and upward from the upper side section of the column side surface 322 of the float 320. Here, “outward” refers to radially outward along the column side surface 322.

[0152] Fig.16 yes Fig.14 A schematic perspective view of a liquid level switch 300 of a liquid storage device 10 is shown.

[0153] The switch body 310 is a rod-shaped plug cover, which has an assembly portion 311 and a blocking portion 312. The assembly portion 311 is a rod, and is fixedly assembled in the mounting hole 342. The blocking portion 312 is a plug cover, and is connected to the top of the assembly portion 311, and is used to open or close the liquid replenishment port 202. The plug cover can be cylindrical, and its upper surface is flat. Compared with the matching structure of the traditional conical head plug and the water spout, the matching mechanism of the plug cover and the lower annular flange of this embodiment has the advantage of high position tolerance, and the plug cover does not need to be precisely aligned with the liquid outlet of the lower annular flange, as long as the upper surface of the plug cover can cover the conical water spout. The plug cover and the rod of this embodiment are an integral part.

[0154] The middle section of the inner wall of the mounting hole 342 is radially inwardly extended to form a middle annular flange 342a. The rod diameter of the main rod 311c of the assembly part 311 is the same as the hole diameter of the middle annular flange 342a, so as to be inserted into the hole defined by the middle annular flange 342a. The assembly part 311 also has an upper annular boss 311a and a lower annular boss 311b extending radially outward from the main rod 311c thereof, which are respectively located above and below the middle annular flange 342a to limit the freedom of movement of the switch body 310 relative to the mounting hole 342.

[0155] By designing the hole structure of the mounting hole 342 and the rod structure and plug structure of the switch body 310 , the structural stability of the overall structure obtained by fixing and assembling the switch body 310 and the mounting hole 342 can be improved.

[0156] In some optional embodiments, the switch body 310 is made of an acid-resistant and alkali-resistant elastic material, such as EPDM or fluororubber, and relies on its own elastic deformation to squeeze the liquid inlet 202 that seals with it, thereby achieving sealing. The rotating shaft 340 is made of an acid-resistant and alkali-resistant material, such as a chrome-plated metal material, a ceramic material, or a plastic material. The float 320 can be made of an acid-resistant and alkali-resistant material such as polytetrafluoroethylene or polybutylene adipamide.

[0157] In some optional embodiments, the first liquid storage container 110 and the first filter housing 120 are respectively made of transparent materials, and the second liquid storage container 210 and the second filter housing 220 are also respectively made of transparent materials. In other optional embodiments, the first liquid storage container 110 and the first filter housing 120 are respectively made of transparent materials, or the second liquid storage container 210 and the second filter housing 220 are respectively made of transparent materials.

[0158] Since the transparent material has an external display function, it is easy for the user to observe the filtering and recovery process of the liquid storage device 10, so as to determine the working state of the liquid storage device 10. By observing whether there is a phenomenon of bubbles rising in the first filter housing 120 or the second filter housing 220, it can be determined whether the electrolytic deoxidation device 20 connected to the liquid storage device 10 is in a working state. In some embodiments, when the liquid storage device 10 and the electrolytic deoxidation device 20 are assembled into a reaction system 2, the gas discharged by the electrolytic deoxidation device 20 can flow through the first filter element 130, the first filter housing 120, the second filter element 230 and the second filter housing 220 in sequence. By observing whether there is a phenomenon of bubbles rising in the first filter housing 120 or the second filter housing 220, it can be determined whether the electrolytic deoxidation device 20 is reacting. The user can infer the amount of electrolyte in the reaction container according to the liquid level in the second liquid storage container 210 and flexibly replenish the electrolyte.

[0159] In some further embodiments, if the second liquid storage portion 200 is illuminated by light, the edge of the bubble can be better highlighted, making the "working appearance" effect more significant. For example, the liquid storage device 10 can install a lighting lamp on the top, bottom or side of the second liquid storage container 210.

[0160] Fig.17 1 is a schematic diagram of the connection structure of the liquid storage device 10 and the electrolytic deoxidation device 20 of the refrigerator 1 according to an embodiment of the present invention. The reaction container is provided with an exhaust port 201 for discharging the gas generated by the chemical reaction. The first air inlet 121 is connected to the exhaust port 201. The reaction container is also provided with a liquid replenishing port 202 for replenishing liquid.

[0161] The refrigerator 1 may further include a plurality of gas pipes 30 and a plurality of liquid pipes 40, wherein one gas pipe 30 is connected between the first air outlet 122 and the second air inlet 221, another gas pipe 30 is connected between the first air inlet 121 and the exhaust port 201, one liquid pipe 40 is connected between the liquid supply port 114 of the first liquid storage container 110 and the liquid replenishment port 202 of the reaction container, and another liquid pipe 40 is connected between the liquid discharge port 216 of the second liquid storage container 210 and the liquid input port 116 of the first liquid storage container 110.

[0162] The reaction container may be provided with an electrochemical reaction element (anode plate, cathode plate, etc.), and may also contain an electrolyte, such as a sodium hydroxide solution, etc. The anode plate and the cathode plate are immersed in the electrolyte, respectively.

[0163] When the electrolytic deoxidation device 20 is installed in the refrigerator 1, the cathode plate can be connected to the airflow of the storage compartment of the refrigerator 1. When powered, the cathode plate is used to consume the oxygen in the storage compartment through an electrochemical reaction. For example, the oxygen in the air can undergo a reduction reaction at the cathode plate, that is, O2+2H2O+4e - →4OH - .

[0164] The anode plate and the cathode plate are disposed in the reaction container 500 at intervals. When powered, the anode plate is used to provide reactants (e.g., electrons) to the cathode through an electrochemical reaction and generate oxygen. - Oxidation reaction can occur at the anode plate and generate oxygen, namely: 4OH - →O2+2H2O+4e - Oxygen can be exhausted through the exhaust port 201 on the reaction vessel.

[0165] The oxygen generated in the reaction container enters the first air duct and is filtered and recovered once in the first filter housing 120, so that the electrolyte carried by the oxygen is retained in the first filter housing 120. The oxygen flowing out of the first exhaust hole may still carry electrolytes, and by allowing it to enter the second air duct and be filtered and recovered twice in the second filter housing 220, the electrolyte carried by the oxygen can continue to dissolve, thereby improving the filtering and recovery efficiency.

[0166] After secondary filtration, the electrolyte content carried by the oxygen flowing out of the second exhaust hole is very small and has dropped to a level that the user can touch, and the electrolyte content dissolved in the second filter shell 220 is also very small. When the user adds liquid to the second liquid storage container 210, or observes bubbles through the second liquid storage container 210 and the second filter shell 220, safety can be guaranteed, making it convenient for non-professionals to perform the liquid adding process.

[0167] Since the reaction container is provided with a liquid inlet 202, the liquid supply port 114 of the first liquid storage container 110 is connected to the liquid inlet 202 of the reaction container, so that the liquid in the first liquid storage container 110 flows through the liquid supply port 114 and the liquid inlet 202 in sequence and enters the reaction container. Another liquid level switch 300 may be provided in the reaction container, which is used to automatically open and close the liquid inlet 202 according to the liquid level in the reaction container. The structure of the liquid level switch 300 is the same as the structure of the liquid level switch 300 mentioned in the above embodiment, and will not be repeated here.

[0168] In this embodiment, since the electrochemical reaction of the electrolytic deoxidation device 20 consumes water, the liquid in the first liquid storage container 110, the first filter shell 120, the second liquid storage container 210 and the second filter shell 220 can be directly water, or can be converted into an electrolyte with a lower concentration.

[0169] By organically cooperating with the liquid storage device 10 and the electrolytic deoxidation device 20, water can be automatically replenished to the electrolytic deoxidation device 20, and the acidic or alkaline components in the exhaust gas generated by the electrolytic deoxidation device 20 can be removed, and the electrolyte that was originally lost can be recovered and reused. The whole process does not require professional personnel to operate, and no electronic components are required. The whole system has the advantages of integration, modularization, and low cost, and can solve the problems of difficulty in replenishing liquid and loss of electrolyte in the deoxygenation process.

[0170] The refrigerator 1 and the control method thereof of the present invention can utilize the liquid storage device 10 to replenish liquid to the reaction container of the electrolytic deoxidation device 20, and when the liquid storage amount of the liquid storage device 10 is higher than a preset value, the electrolytic deoxidation device 20 is allowed to be started, thereby ensuring that the electrolytic deoxidation device 20 is started when the liquid supply is sufficient. Therefore, based on the solution of the present invention, the continuity and effectiveness of the deoxygenation process of the refrigerator 1 can be guaranteed.

[0171] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
