Detailed Description

Fig. 1 is a schematic block diagram of a refrigerator 1 according to an embodiment of the present invention.

The refrigerator 1 comprises an electrolytic oxygen removing device 20, a liquid storage device 10, a processor 81 and a memory 82, wherein the electrolytic oxygen removing device 20 is used for consuming oxygen in a storage space of the refrigerator 1 through electrochemical reaction under the action of electrolytic voltage, and the liquid storage device 10 is used for supplementing liquid to a reaction container of the electrolytic oxygen removing device 20.

The processor 81 and the memory 82 may form a control device 80 of the refrigerator 1, for example, the control device 80 may be a main control chip. The memory 82 stores a machine executable program 821, and the machine executable program 821 when executed by the processor 81 is used to implement the control method of the refrigerator 1 of any one of the following embodiments. The processor 81 may be a Central Processing Unit (CPU), or a digital processing unit (DSP), or the like. The memory 82 is used to store programs executed by the processor 81. Memory 82 may be any medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited to such. The memory 82 may also be a combination of various memories. Since the machine executable program 821 realizes each process of the method embodiments described below when executed by the processor 81 and achieves the same technical effects, the description thereof is omitted for avoiding repetition.

Fig. 2 is a schematic view of a control method of the refrigerator 1 according to an embodiment of the present invention.

The control method may generally include the steps of:

in step S202, the amount of the liquid stored in the liquid storage device 10 is detected. The amount of fluid stored in the fluid storage device 10 may be characterized by either fluid level or volume. The amount of liquid stored in the liquid storage device 10 is used to measure whether the liquid supply of the electrolytic oxygen removing device 20 is sufficient.

In step S204, in the case that the liquid storage amount is higher than the preset value, the electrolytic oxygen removing device 20 is allowed to be started. The preset value may be set according to the amount of liquid consumed by the electrochemical reaction performed by the electrolytic oxygen removing device 20 in a set period of time, and the average value is obtained as the preset value by measuring multiple times.

The permission to start the electrolytic oxygen removing device 20 is relative to "permission to start the electrolytic oxygen removing device 20", in which case the electrolytic oxygen removing device 20 is permitted to start, the electrolytic oxygen removing device 20 can be controlled to start according to the actual oxygen removing demand, and in which case the electrolytic oxygen removing device 20 is not permitted to start, even if the storage space has the oxygen removing demand, the electrolytic oxygen removing device 20 cannot start.

With the above method, since the liquid storage device 10 can be used to replenish liquid to the reaction vessel of the electrolytic oxygen removing device 20, and the electrolytic oxygen removing device 20 is allowed to be started under the condition that the liquid storage amount of the liquid storage device 10 is higher than the preset amount, the electrolytic oxygen removing device 20 is ensured to be started under the condition that the liquid supply is sufficient, and therefore, the continuity and the effectiveness of the oxygen removing process of the refrigerator 1 can be ensured based on the scheme of the invention.

The liquid storage device 10 comprises a first liquid storage container 110 and a second liquid storage container 210, wherein the first liquid storage container 110 is communicated with the reaction container of the electrolytic oxygen removing device 20 and is used for supplementing liquid to the reaction container, and the second liquid storage container 210 is communicated with the first liquid storage container 110 and is used for supplementing liquid to the first liquid storage container 110. That is, the liquid in the second liquid storage container 210 may flow into the first liquid storage container 110 first and then into the reaction container.

The step of detecting the amount of liquid stored in the liquid storage device 10 includes: the liquid level of the second liquid storage container 210 is detected, and the liquid storage amount of the liquid storage device 10 is determined according to the liquid level of the second liquid storage container 210. For example, a liquid level sensor is disposed in the second liquid storage container 210 to detect the liquid level of the second liquid storage container 210.

For example, the liquid level of the liquid storage device 10 is used to characterize the liquid storage amount, and the preset value is also used to characterize the liquid level, and 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 amount of the liquid storage device 10 is higher than the preset value.

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 requirement, and the control process is simple.

The second liquid storage container 210 is provided with a liquid filling port 602b for filling liquid, and a user can fill the second liquid storage container 210 with liquid from the external environment through the liquid filling port 602b, thereby completing the filling of the second liquid storage container 210.

In some embodiments, after the step of detecting the amount of fluid stored in the fluid reservoir 10, the control method further comprises: in the case that the liquid storage amount is not higher than the preset amount, a liquid supplementing prompt signal is output to prompt the user to supplement liquid to the liquid filling port 602b of the second liquid storage container 210.

By using the method, whether the liquid storage amount of the liquid storage device 10 meets the requirement can be automatically evaluated, and a user can be urged to timely supplement liquid to the second liquid storage container 210 of the liquid storage device 10, so that the normal operation of the electrolytic oxygen removal device 20 is ensured, and the continuity and the effectiveness of the oxygen removal process are ensured.

The liquid supply amount of the electrolytic oxygen removing device 20 can be improved to some extent by using the two liquid storage containers as the liquid replenishing bins of the electrolytic oxygen removing device 20. The liquid storage device 10 and the electrolytic oxygen removing device 20 are separated and independently arranged, so that the direct liquid supplementing to the electrolytic oxygen removing device 20 can be avoided, the liquid supplementing process can be simplified, the liquid storage device 10 can be prevented from occupying too much low-oxygen fresh-keeping space, and the utilization rate of the low-oxygen fresh-keeping space is improved.

In some embodiments, a reset switch is provided on the power circuit in which the electrolytic oxygen removal device 20 is located. And the control method can further comprise the following steps when the liquid supplementing prompt signal is output: the reset switch is controlled to switch to the open state so that the power supply loop is disconnected at the reset switch.

For example, a switching element may be provided on the power supply circuit, and the electrolytic voltage of the electrolytic oxygen removing device 20 may be turned off or on by controlling the switching element to be opened or closed. The reset switch may be placed in the power supply loop in series with the electrolytic oxygen removal device 20. When the reset switch is in the off state, the power supply circuit is still in the off state even if the switching element is closed, and the electrolytic oxygen removing device 20 cannot be electrified and started.

By using the method, the state of the reset switch on the power supply loop is regulated and controlled, and the electrolytic oxygen removing device 20 can be prevented from being started without permission under the condition of insufficient liquid supply, so that the scheme of the embodiment can utilize simple and smart control logic to improve the operation reliability of the electrolytic oxygen removing device 20, and the electrolytic oxygen removing device 20 cannot be electrified and started due to the connection of electrolytic voltage, thereby avoiding electric energy waste or safety accidents.

After controlling the reset switch to the off state, the control method may further include: the amount of the liquid stored in the liquid storage device 10 is detected again, and in case that the amount of the liquid stored is higher than a preset value, the reset switch is controlled to be switched to a short-circuit state, so that the power supply loop is switched on at the reset switch, and the electrolytic oxygen removing device 20 is allowed to be started. That is, the step of allowing the electrolytic oxygen removing device 20 to be started is to switch the reset switch to the short-circuit state, or to maintain the short-circuit state.

That is, by adjusting the state of the reset switch, the electrolytic oxygen removal device 20 may or may not be activated. When the reset switch is in a short-circuit state, the on-off of the power supply circuit is controlled only by the switching element, and the switching element can be connected with the control device 80 of the refrigerator 1 in a data manner, so that the on-off state of the switching element can be controlled by the control device 80. For example, in the case that the storage space has a deoxidizing requirement, the control device 80 can communicate with the entire power supply circuit by controlling the switching element to be closed, so that the electrolytic deoxidizing device 20 turns on the electrolytic voltage and starts the electrochemical reaction. When the reset switch is in the off state, the on/off of the power supply circuit is no longer controlled by the switching element, and even if the switching element is closed, the entire power supply circuit cannot be connected, and the electrolytic oxygen removing device 20 cannot switch on the electrolytic voltage.

In some alternative embodiments, after activating the electrolytic oxygen removal device 20, the control method may further include: the liquid level change values of the first liquid storage container 110 and the second liquid storage container 210 are obtained, and the working state of the liquid storage device 10 and/or the deoxidizing efficiency of the electrolytic deoxidizing device 20 are determined according to the liquid level change values of the first liquid storage container 110 and the second liquid storage container 210.

Since the second liquid storage container 210 is communicated with the first liquid storage container 110 and the first liquid storage container 110 is communicated with the reaction container, the working state of the liquid storage device 10 and/or the deoxidizing efficiency of the electrolytic deoxidizing 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 that whether the liquid storage device 10 and the electrolytic deoxidizing device 20 are in normal operation can be judged, and the method is simple and effective.

For example, by analyzing the liquid level change values of the first liquid storage container 110 and the second liquid storage container 210 in a set period of time, the electrolyte consumption amount of the electrolytic oxygen removing device 20 can be determined, and since the electrolytic oxygen removing device 20 consumes a unit volume of electrolyte and has a fixed theoretical oxygen consumption value, the actual oxygen consumption amount of the electrolytic oxygen removing device 20 can be determined from the obtained electrolyte consumption amount and the theoretical oxygen consumption value, and thus the actual oxygen consumption rate can be determined. The oxygen consumption rate is the oxygen removal efficiency of the electrolytic oxygen removal device 20.

For another example, in the set period of time, by analyzing the liquid level change values of the first liquid storage container 110 and the second liquid storage container 210, if the liquid level change values of the two liquid storage containers are not matched, it can be determined that the liquid storage device 10 is in an abnormal state and needs to be overhauled. For example, if the liquid level change value of the first liquid storage container 110 is greater than the preset first change threshold value, and the liquid level change value of the second liquid storage container 210 is zero or less than the preset second change threshold value, it may be determined that the liquid level change values of the two liquid storage containers are not matched.

In some alternative embodiments, prior to the step of detecting the reservoir volume of the reservoir device 10, the control method may further include: it is determined that the reservoir 10 is in the preset operating position. When the liquid storage device 10 is at the preset working position, the normal communication between the first liquid storage container 110 and the reaction container can be ensured.

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 operating position includes: the detection value of the pressure sensor installed below the liquid storage device 10 is acquired, and the liquid storage device 10 is determined to be in the working position when the detection value of the pressure sensor is greater than a preset detection threshold value. The detection threshold may be set based on the weight of the reservoir 10 itself (without the liquid).

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 filling, and since the liquid storage amount in the liquid filling process is continuously changed, the step of detecting the liquid storage amount of the liquid storage device 10 is performed under the condition that the liquid storage device 10 is determined to be in the working position by using the method, so that the effectiveness of the detection result can be improved.

Fig. 3 is a control flow chart of the refrigerator 1 according to one embodiment of the present invention. The control flow may generally include the steps of:

in step S302, a detection value of a pressure sensor mounted below the liquid storage device 10 is acquired.

In step S304, it is determined that the liquid storage device 10 is in the working position when the detection value of the pressure sensor is greater than the preset detection threshold.

In step S306, the liquid level of the second liquid storage container 210 is detected.

In step S308, the liquid storage amount of the liquid storage device 10 is determined according to the liquid level of the second liquid storage container 210.

Step S310, determining whether the liquid storage amount of the liquid storage device 10 is higher than a preset amount, if yes, executing step S312, and if not, executing step S314.

Step S312 allows the electrolytic oxygen removal device 20 to be started.

In step S314, a fluid replacement prompt signal is output to prompt the user to replace the fluid in the fluid inlet 602b of the second fluid reservoir 210.

In step S316, the reset switch is controlled to switch to the off state, so that the power supply loop is disconnected at the reset switch.

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

in step S320, when the stored liquid level is higher than the preset level, the reset switch is controlled to switch to the short-circuit state, so that the power supply circuit is turned on at the reset switch, and the electrolytic oxygen removing device 20 is allowed to be started.

Step S322, acquiring a start signal of the electrolytic oxygen removing device 20. That is, after the electrolytic oxygen removing device 20 is started, the following steps S324 to S326 are performed.

In step S324, the liquid level change values of the first liquid storage container 110 and the second liquid storage container 210 are obtained.

In step S326, the operating state of the liquid storage device 10 and/or the oxygen removal efficiency of the electrolytic oxygen removal device 20 is determined according to the liquid level change values of the first liquid storage container 110 and the second liquid storage container 210.

According to the refrigerator 1 and the control method thereof, the liquid storage device 10 can be utilized to supplement liquid to the reaction container of the electrolytic oxygen removing device 20, and under the condition that the liquid storage quantity of the liquid storage device 10 is higher than the preset quantity, the electrolytic oxygen removing device 20 is allowed to be started, so that the electrolytic oxygen removing device 20 is ensured to be started under the condition that the liquid supply is sufficient, and therefore, the continuity and the effectiveness of the oxygen removing process of the refrigerator 1 can be ensured based on the scheme of the invention.

In some alternative embodiments, the liquid storage device 10 is retractably disposed in the refrigerator 1, so as to facilitate liquid supplementing for a user and operation for the user.

For example, the antimicrobial and mildew-proof module can be an evenly distributed antimicrobial and mildew-proof agent, which is nontoxic and harmless.

To facilitate the user to supplement the second liquid storage container 210, the box body 150 may be provided with a liquid injection port (not shown) above the liquid injection port 602b, where a flip cover 151 is disposed, and the user turns over the flip cover 150 to open and close the liquid injection port.

Fig. 6 is a schematic structural view of the liquid storage device 10 according to one embodiment of the present invention. Fig. 7 is a schematic top view of the fluid reservoir 10 shown in fig. 6. Fig. 8 is a schematic front view of the fluid reservoir 10 shown in fig. 6. Wherein fig. 8 is a perspective view. The liquid storage device 10 of the present embodiment has a filtering and recovering function, and can separate and recover specific substance components in the gas for use.

The reservoir 10 may generally include a first reservoir 100 and a second reservoir 200.

Wherein the first liquid storage part 100 has a first filter housing 120 and a first filter 130. The first filter housing 120 and the first filter member 130 form a first filter mechanism.

The first gas outlet 122 is used for discharging the filtered gas.

The first filter housing 120 may also be used to hold a liquid, such as an electrolyte containing a specific component or water. The dissolution of the specific substance component in the gas from the external environment of the liquid storage device 10 into the first filter housing 120 means dissolution into the liquid stored in the first filter housing 120.

The second reservoir 200 has a second filter housing 220 and a second filter 230. The second filter housing 220 and the second filter 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 hole 221 is communicated with the first air outlet hole 122, and the second filter 230 is disposed in the second filter housing 220 and is used for dissolving specific substance components in the air passing through the second air inlet hole 221 from the first air outlet hole 122 into the second filter housing 220 so as to realize secondary filtration and recovery. The second air outlet 222 is used for discharging the gas after being filtered again.

The second filter housing 220 may also be used to hold a liquid, such as an electrolyte containing a specific component or water. The dissolution of the specific substance component in the gas from the external environment of the liquid storage device 10 into the second filter housing 220 means dissolution into the liquid stored in the second filter housing 220.

In this embodiment, the specific substance component is a water-soluble substance. In some alternative embodiments, the liquid composition stored by the first filter housing 120 and the second filter housing 220 may be adjusted according to the physicochemical properties of the particular material composition to be separated.

In the liquid storage device 10 of the present embodiment, the first filter 130 and the first filter housing 120 can be used to dissolve the specific substance component in the gas introduced into the first air inlet 121 into the first filter housing 120, so as to achieve filtering recovery, and the second filter 230 and the second filter housing 220 can be used to dissolve the specific substance component in the gas introduced into the second air inlet 221 from the first air outlet 122 into the second filter housing 220, so as to achieve re-filtering recovery, so the present embodiment provides the liquid storage device 10 with filtering recovery function, and the liquid storage device 10 can separate and recover the specific substance component in the gas, thereby reducing or avoiding pollution caused by gas emission, and improving the resource utilization efficiency.

The first liquid storage part 100 and the second liquid storage part 200 are utilized to carry out organic combination, and specific substance components in the gas introduced into the first air inlet hole 121 are filtered and recovered for a plurality of times, so that the filtering efficiency and the recovery efficiency of the liquid storage device 10 are improved, and the exhaust emission pollution and the resource waste can be further reduced.

It should be noted that the number of the second filtering portions may be set to one or more according to actual needs, so as to adjust the number of times of filtering and recycling. The present embodiment is exemplified only for the case where the number of second filter portions is one, but should not be construed as limiting the number of second filter portions.

In some alternative embodiments, the first reservoir 100 further has a first reservoir 110, and the first filter housing 120 communicates with the first reservoir 110 to allow the particular substance component dissolved in the first filter housing 120 to enter the first reservoir 110.

Because each filter shell is respectively provided with a liquid storage container which is correspondingly communicated with the filter shell, the specific substance components remained in each filter shell can be converged to the corresponding liquid storage container so as to realize reutilization.

As for the communication manner between each filter housing and the corresponding liquid storage container, for example, each filter housing may be inserted into the corresponding liquid storage container. Each liquid storage container can be approximately rectangular, and each filter shell can be inserted into the corresponding liquid storage container as an inner sleeve.

Specifically, the first filter housing 120 is inserted into the first liquid storage container 110, and a first liquid outlet hole 123 communicating with the first liquid storage container 110 is formed at the bottom of the first filter housing 120 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 communicating with the second liquid storage container 210 is formed at the bottom of the second filter housing 220 to allow the liquid in the second filter housing 220 to flow into the second liquid storage container 210.

Because each filter shell is communicated with the corresponding liquid storage container through the liquid outlet hole at the bottom, liquid in each filter shell can downwards pass through the liquid outlet hole by means of self gravity and flow back into the liquid storage container, and the recovery process of the liquid storage device 10 is simple and effective.

The above examples of communication means are only illustrative, and a person skilled in the art should easily expand the examples, which are not enumerated here.

In some alternative embodiments, the second reservoir 210 communicates with the first reservoir 110. And the first liquid storage container 110 is provided with a liquid supply port 114 communicated with the external environment for supplementing liquid to the external environment. That is, the liquid storage device 10 of the present embodiment has both the filtration and recovery function and the liquid replenishing function while storing the liquid, which facilitates reuse of the specific substance components obtained by filtration and recovery. For example, the specific material component in the first liquid storage container 110 can be reused by some devices in the external environment after flowing out from the liquid supply port 114. The specific material component entering the second reservoir 210 may first enter the first reservoir 110 and then flow out through the fluid supply port 114 for reuse by some devices in the external environment.

Fig. 9 is a schematic side view of a part of the structure of the liquid storage device 10 shown in fig. 7. Fig. 10 is a schematic structural view of a part of the structure of the liquid storage device 10 shown in fig. 7. Fig. 9 and 10 are perspective views, and fig. 10 shows a perspective part with a broken line.

In some alternative embodiments, the second reservoir 210 has a common wall with the first reservoir 110, and a portion of the bottom wall 211 of the second reservoir 210 forms the common first wall 111 and second wall 112 by being upwardly concave (i.e., upwardly concave). That is, the common wall includes a first wall 111 and a second wall 112. Wherein the first wall 111 serves as a side wall of the first reservoir 110, which may extend along a vertical plane. The second wall 112 serves as a portion of the top wall of the first reservoir 110, which may extend along a horizontal plane. If the bottom wall 211 of the second liquid storage container 210 is not recessed, the second liquid storage container 210 has a substantially rectangular parallelepiped shape. By recessing a portion of the bottom wall 211 of the second reservoir 210 and forming the first wall 111 and the second wall 112 in common, a portion of the first reservoir 110 may be positioned below the second reservoir 210.

The second wall 112 is provided with an opening 112a for communicating the second liquid storage container 210 with the first liquid storage container 110. This may cause the liquid in the second reservoir 210 to flow down into the first reservoir 110 via the opening 112a by its own weight. The liquid supplementing process of the embodiment has no external pump driving and no noise.

In some alternative embodiments, the first air inlet holes 121 and the first air outlet holes 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, and extends horizontally outward from the second wall 112 toward a direction away from the second liquid storage container 210. The second wall 112 and the third wall 113 of the present embodiment are connected in a horizontal plane to serve as a 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 the third wall, which facilitates the opening of the first air inlet hole 121 and the first air outlet hole 122.

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

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

In some alternative embodiments, the second reservoir 210 and the first reservoir 110 may be converted from the integrated arrangement described above to a separate stand-alone arrangement. At this time, the second liquid storage container 210 is provided with a liquid outlet 216, the first liquid storage container 110 is provided with a liquid inlet 116, and the two liquid storage containers can be communicated by communicating the liquid outlet 216 with the liquid inlet 116.

Since the two filter mechanisms have the same structure, only the first filter mechanism is selected as an example, and the structure thereof will be described below. Fig. 11 is a schematic structural view of a first filter mechanism of the liquid storage device 10 shown in fig. 7. Fig. 12 is a schematic exploded view of a first filter mechanism of the fluid reservoir 10 shown in fig. 11.

The first filter 130 and the second filter 230 are air ducts, respectively, and extend downward from the first air intake holes 121 and the second air intake holes 221, respectively, to a bottom section within the first filter housing 120 and a bottom section within the second filter housing 220. For example, the first filter 130 may be named a first airway and the second filter 230 may be named a second airway. The first air duct is inserted downward into the first filter housing 120 from the first air intake hole 121 and extends to a bottom section in the first filter housing 120. The second air duct is inserted downward into the second filter housing 220 from the second air inlet hole 221 and extends to a bottom section in the second filter housing 220.

The two air ducts respectively extend to the bottom sections in the corresponding filter shells, and the air flowing through the air ducts can be guided to the bottom sections in the corresponding filter shells, so that the flow path of the air in the filter shells is prolonged, the air flowing out of the air ducts can be fully contacted with the liquid in the filter shells in the rising process, the specific substance components in the air can be fully dissolved in the filter shells, and the liquid storage device 10 can obtain a better filtering and purifying effect with a exquisite and simple structure.

The air duct of this embodiment may be a straight tube, and both ends thereof are provided with openings 112a, so as to facilitate the air to be introduced or discharged, and has a simple structure and a better air guiding effect.

In some alternative embodiments, the shape of the airway tube may be transformed into a vertical bend-like tube having a straight tube section and a bend section extending from the end of the straight tube section in a bend-up direction. The end of the curved tube section is slightly higher than the end of the straight tube section for directing the gas flowing therethrough upward.

That is, the air duct of this embodiment may take the shape of a vertical hook, with the straight tube section resembling an umbrella shaft and the curved tube section resembling an umbrella stem attached to the end of the umbrella shaft. The bent pipe end is bent upwards from the tail end of the straight pipe section, so that the gas flowing out of the gas guide pipe is guided to flow upwards, and the movement direction of the gas is more definite. By the end of the bent pipe section being slightly higher than the end of the straight pipe section is meant that the end of the bent pipe section is still in the bottom section of the filter housing, which does not significantly shorten the flow path of the gas during dissolution.

Adopt air duct and filter housing mutually support, realize utilizing water to carry out gas filtration, can avoid using the loss nature filter media, and need not to change the filter media, be favorable to practicing thrift the cost.

In some alternative embodiments, each filter housing may be integrally formed. In other alternative embodiments, the filter housing may be formed from a plurality of different components. For example, each filter housing may include a first cartridge body 501 having a top opening 112a and a first cartridge cover 502 closing the top opening 112a of the first cartridge body 501, respectively. And the air inlet and outlet holes are spaced apart from each other on the first cover 502. The first bin 501 may be straight and has a tube diameter greater than that of the air duct. The top end of the first bin 501 is shaped like an opening 112a and is in sealing connection with the first bin cover 502. The bottom end of the first bin 501 is closed, and the liquid outlet hole is formed on the bottom end. The number of the liquid outlet holes can be at least one.

The air inlet hole, the air duct and the air outlet hole are covered by the first bin body 501 to form a sleeve structure. The bottom of the air duct is higher than the bottom of the first bin 501, so that the air flowing out of the air duct is prevented from escaping from the first bin 501.

In some alternative embodiments, the first reservoir 110 and the second reservoir 210 may be formed as a single piece, which is advantageous in improving the sealing effect of the reservoirs and preventing leakage. In alternative embodiments, the second reservoir 210 may be transformed from a plurality of different components connected. For example, the second reservoir 210 may include a second cartridge body 601 having a top opening 112a and a second cap 602 closing the top opening 112a of the second cartridge body 601. The second bin 601 may be in the shape of a rectangular water tank without a cover, and its volume is larger than that of the first bin 501.

Fig. 13 is a schematic structural view of a second cartridge cover 602 of the second reservoir 210 of the reservoir device 10 shown in fig. 8. Fig. 13 (a) is a perspective view, fig. 13 (b) is a front view, and fig. 13 (c) is a plan view.

The second cover 602 is provided with a mounting opening 602a. The hole wall of the mounting hole 602a is extended upward to form a hollow cylindrical male screw joint 602e. Since the male screw joint 602e is formed to extend upward from the wall of the mounting port 602a, the upper edge of the male screw joint 602e is higher than the upper surface of the second housing cover 602 and also higher than the upper edge of the filling groove 602c described below. This may control the maximum level of the priming process below the upper edge of the externally threaded interface 602e.

The first cartridge cover 502 has a closure deck 502a located above the first cartridge body 501 and an annular female threaded interface 502b extending downwardly from the outer periphery of the closure deck 502 a. Wherein, the closing cover 502a is used for shielding the top opening 112a of the first bin 501. The annular internal threaded interface 502b is threaded with the external threaded interface 602e such that the first cartridge cap 502 is removably coupled with the second cartridge cap 602. That is, the annular internally threaded interface 502b is used to connect the first cartridge cap 502 to the second cartridge cap 602.

The first cartridge 501 extends downwardly from the lower surface of the closure cap 502a and is inserted into the reservoir after passing through the externally threaded interface 602e.

The first bin cover 502 and the second bin cover 602 are in threaded connection to seal the mounting opening 602a, so that the mounting and fixing process of the second filter mechanism can be simplified, and one-step mounting can be realized.

In some alternative embodiments, second cartridge cover 602 may be provided with a filling port 602b having a wall extending downward to form filling slot 602c. Since the filling groove 602c extends downward from the upper surface of the second cap 602 and the male screw port 602e extends upward from the upper surface of the second cap 602, when liquid is added from the filling port 602b to the second cartridge 601, the liquid level does not exceed the male screw port 602e even if the filling process causes overflow of the second cartridge 601.

A portion of the groove wall of charging groove 602c is provided to extend obliquely downward so that the bottom of charging groove 602c forms tapered opening 112a. That is, the water adding tank is an inclined through hole with a certain depth, which is convenient for a user to observe the liquid level condition during liquid adding. The tank wall extending obliquely downwards is provided with a liquid level mark to prompt the liquid level in the liquid adding process. For example, the level indicator may be designed as a "top level tick mark" for prompting the user that the liquid is filled.

In some alternative embodiments, the edge of the second cartridge cover 602 has a protrusion 602d that protrudes outward for application of force. The user can apply force to the second cover 602 through the actions such as grabbing, so as to realize the disassembly and assembly process between the second cover 602 and the second cover 601.

An elastic sealing ring can be arranged on the periphery of the closed position between the second bin cover 602 and the second bin body 601, so that sealing can be realized through pressing between the second bin cover 602 and the second bin body 601 conveniently, and water leakage of the second bin body 601 is prevented.

The first liquid storage container 110 is integrally formed. In order to realize the assembly of the first filter mechanism, the third wall 113 of the first liquid storage container 110 is also provided with an installation opening 602a, the appearance of the installation opening 602a is the same as that of the installation opening 602a on the second bin cover 602, and the assembly mode of the first filter mechanism relative to the installation opening 602a is the same as that of the second filter mechanism relative to the installation opening 602a, which is not repeated herein.

Fig. 14 is a schematic structural view of the liquid level switch 300 of the liquid storage device 10 shown in fig. 7. Fig. 15 is a schematic exploded view of the fluid level switch 300 of the fluid reservoir 10 shown in fig. 14.

In some further embodiments, the fluid storage device 10 may further include a fluid level switch 300 disposed within the first fluid storage container 110 and having a switch body 310 for moving according to the fluid level within the first fluid storage container 110 to open and close the opening 112a to allow or prevent fluid within the second fluid storage container 210 from flowing into the first fluid storage container 110 through the opening 112 a. That is, the liquid level switch 300 is used to control the opening and closing of the opening 112 a. That is, the liquid level switch 300 serves as a gate of the infusion path between the second liquid storage container 210 and the first liquid storage container 110, and serves to open and close the infusion path. 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 is not required to be controlled electrically. Fig. 14 (a) shows a state when the switch body 310 closes the opening 112a, fig. 14 (b) shows a state when the switch body 310 opens the opening 112a, and an arrow direction in the drawing shows a rotation direction of the float 320.

The switch body 310 may rise and abut against the lower periphery of the opening 112a in the case that the liquid level in the first liquid storage container 110 rises so as to close the opening 112a, such that the liquid in the second liquid storage container 210 cannot pass through the opening 112a, and may also fall and deviate and open the opening 112a in the case that the liquid level in the first liquid storage container 110 falls, such that the liquid in the second liquid storage container 210 may 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 be in direct contact, and a certain height distance can be kept, so that solution substances are prevented from migrating due to liquid merging, and pollution is avoided.

The liquid level switch 300 further includes a float 320 fixedly connected to the switch body 310 or integrally formed with the switch body 310, for driving the switch body 310 to move in the first liquid storage container 110 through a floating or sinking motion. That is, the switch body 310 is "driven" by the float 320, and the power required to move the float 320 is determined by the buoyancy it receives within the first reservoir 110.

For example, a portion of the float 320 is immersed in the liquid, thereby subjecting the float 320 to buoyancy by the liquid. When the liquid level in the first liquid storage container 110 changes, the buoyancy force exerted by the float 320 also changes, so that the resultant force of the buoyancy force and the gravity force exerted by the float 320 changes. For example, when the liquid level in the first reservoir 110 decreases, the buoyancy force exerted by the float 320 decreases, and if the resultant force of the buoyancy force exerted by the float 320 and the gravity force is downward, the float 320 is caused to move downward. Conversely, this will cause the float 320 to move upwardly. The float 320 may rise or fall in a vertical direction, or may rise or fall in a curve.

In some alternative embodiments, the float 320 is rotatably disposed about an axis. That is, the float 320 of the present embodiment does not move up and down along a straight line, but moves up or down in a pivoting manner, and thus, the float 320 is only required to be pivotally connected to a fixed shaft, and a guide member having high dimensional accuracy is not required to be installed, so that the present embodiment has the advantages of compact structure, simple assembly process, and good device reliability.

Since the float 320 is rotatably disposed around the shaft, the movement track is clear and definite, so that the float 320 and the switch body 310 of the embodiment are easy to move along the clear and definite movement track, thereby improving the reliability of the liquid level switch 300 and reducing or avoiding the problem of sealing inaccuracy caused by the free movement of the float 320.

The fluid level switch 300 may further include a rotation shaft 340 and a connection 330.

Wherein the rotation shaft 340 is fixed to the first liquid storage container 110. For example, the rotation shaft 340 may 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.

In some alternative embodiments, the rotation shaft 340 may also be detachably fixed to the first liquid storage container 110, which may adjust the height of the rotation shaft 340 according to actual needs, so as to adjust the liquid level in the first liquid storage container 110 from which the liquid replenishment starts.

The connection member 330 is fixedly connected with the float 320 or is an integral piece with the float 320, and has a shaft hole 341 formed thereon for the rotation shaft 340 to be inserted therein and rotatably fitted to achieve the rotatable connection. That is, the connection 330 assembles the rotation shaft 340 and the float 320 into an organic whole such that the float 320 can rotate about the rotation shaft 340.

By providing the shaft hole 341 in the connector 330 and rotatably fitting the rotation shaft 340 to the shaft hole 341, the float 320 can be rotatably fitted to the rotation shaft 340 around the shaft, and the structure is fine and the process is simple.

The switch body 310 has a rod shape. The connection member 330 is further formed with a mounting opening 602a for inserting a portion of the switch body 310 therein to achieve a fixed assembly. That is, a portion of the switch body 310 is fixedly coupled with the float 320 indirectly by being fixedly assembled with the coupling member 330. For example, a portion of the switch body 310 may be assembled with the mounting opening 602a of the connector 330 by an interference fit.

The rotation shaft 340 and the switch body 310 are assembled to the connection member 330 fixedly connected to the float 320 or integrally formed with the float 320, respectively, thereby forming the liquid level switch 300 with strong structural integrity. The switch body 310 and the float 320 are located on the same side of the rotation shaft 340. The fact that the switch body 310 is on the same side as the floater 320 means that the switch body 310 is located between the rotating shaft 340 and the floater 320 is the key that the switch body 310 makes the 'same direction movement' with the floater 320 according to the liquid level of the inner space of the first liquid storage container 110, and a larger 'moment arm ratio' can be obtained.

In this embodiment, the central axis of the rotation shaft 340 extends in the horizontal direction and is perpendicular to the central longitudinal vertical symmetry plane of the float 320. For example, for a cylindrical float 320, when the two bottom surfaces 321 of the float 320 are disposed opposite in the horizontal direction, the central longitudinal vertical symmetry plane of the float 320 is the longitudinal central section of the float 320 extending in the vertical direction. In the case where the switch body 310 closes the fluid-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 center section of the float 320 extending in the vertical direction. The azimuthal terms such as "horizontal" and "longitudinal" are all relative to the actual use state of the liquid level switch 300, and the longitudinal direction is substantially vertical.

In some alternative embodiments, float 320 is hollow cylindrical. The cylindrical body of the float 320 of this embodiment has a hollow structure, so that buoyancy (overall density is smaller than that of the liquid) can be further improved. The central axis of the float 320 is parallel to the central axis of the shaft hole 341. Wherein the central axes of the floats 320 are respectively 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 disposed opposite to each other in the horizontal direction.

In some alternative embodiments, the connector 330 is cantilevered and extends obliquely outward and upward from an upper section of the cylinder side 322 of the float 320. Wherein "outwardly" refers to radially outwardly along the cylinder sides 322.

Fig. 16 is a schematic perspective view of the fluid level switch 300 of the fluid reservoir 10 shown in fig. 14.

The switch body 310 is a rod-shaped plug cover, and has a fitting portion 311 and a blocking portion 312. Wherein the fitting portion 311 is a rod and is fixedly fitted to the mounting hole 342. The plugging portion 312 is a plug cover, and is connected to the top of the fitting portion 311, for opening or closing the fluid infusion port 202. The plug cover can be cylindrical, and the upper surface of the plug cover is planar. Compared with the matching structure of the traditional conical head plug and the water nozzle, the matching mechanism of the plug cover and the lower annular flange of the embodiment has the advantage of high position fault tolerance, the plug cover does not need to be precisely aligned with the liquid outlet of the lower annular flange, and the conical water nozzle can be covered on the upper surface of the plug cover. The plug cover and the rod of the embodiment are integrated.

A central section of the inner wall of the mounting hole 342 is formed with a central annular flange 342a extending radially inward. The main body rod 311c of the fitting portion 311 has the same rod diameter 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 fitting portion 311 also has an upper annular boss 311a and a lower annular boss 311b extending radially outwardly from the main body stem 311c thereof, above and below the middle annular flange 342a, respectively, to limit the degree of freedom of movement of the switch body 310 with respect to the mounting hole 342.

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 the fixed assembly between the switch body 310 and the mounting hole 342 can be improved.

In some alternative embodiments, the switch body 310 is made of an acid and alkali resistant elastic material, such as ethylene propylene diene monomer rubber or fluororubber, and the like, and presses the fluid infusion port 202 in sealing engagement therewith by virtue of elastic deformation thereof, thereby achieving sealing. The rotation shaft 340 is made of an acid and alkali resistant material such as a chrome plated metal material, a ceramic material, or a plastic material. The float 320 may be made of an acid and alkali resistant material such as polytetrafluoroethylene or polybutylene adipamide.

In some alternative embodiments, the first reservoir 110 and the first filter housing 120 are each made of a transparent material, and the second reservoir 210 and the second filter housing 220 are also each made of a transparent material. In other alternative embodiments, the first reservoir 110 and the first filter housing 120 are each made of a transparent material, or the second reservoir 210 and the second filter housing 220 are each made of a transparent material.

Since the transparent material has an external display function, it is easy for the user to observe the filtering recovery process of the liquid storage device 10, thereby determining the operation state of the liquid storage device 10. By observing whether there is a bubble rising phenomenon in the first filter housing 120 or the second filter housing 220, it is possible to determine whether the electrolytic oxygen removing device 20 connected to the liquid storage device 10 is in an operating state. In some embodiments, when the liquid storage device 10 and the electrolytic oxygen removing device 20 are assembled into the reaction system 2, the gas discharged from the electrolytic oxygen removing device 20 may sequentially flow through the first filter member 130, the first filter housing 120, the second filter member 230 and the second filter housing 220, and whether the electrolytic oxygen removing device 20 is reacting may be determined by observing whether there is a bubble rising phenomenon in the first filter housing 120 or the second filter housing 220. The user can self-infer the electrolyte amount in the reaction vessel according to the liquid level in the second liquid storage vessel 210, and flexibly supplement the electrolyte.

In some further embodiments, if the lighting of the second liquid storage portion 200 is increased, the edge of the air bubble can be better highlighted, so that the "work highlight" effect is better and more remarkable. For example, the liquid storage device 10 may be provided with illumination lamps at the top, bottom, or side of the second liquid storage container 210.

Fig. 17 is a schematic view of a connection structure of the liquid storage device 10 and the electrolytic oxygen removing device 20 of the refrigerator 1 according to an embodiment of the present invention. The reaction vessel is provided with an exhaust port 201 for exhausting gas generated by the chemical reaction. The first intake holes 121 communicate with the exhaust port 201. The reaction vessel is also provided with a fluid infusion port 202 for fluid infusion.

The refrigerator 1 may further include a plurality of air delivery pipes 30 and a plurality of infusion pipes 40, wherein one air delivery pipe 30 is connected between the first air outlet 122 and the second air inlet 221, the other air delivery pipe 30 is connected between the first air inlet 121 and the air outlet 201, one infusion pipe 40 is connected between the liquid supply port 114 of the first liquid storage container 110 and the liquid supplementing port 202 of the reaction container, and the other infusion pipe 40 is connected between the liquid outlet 216 of the second liquid storage container 210 and the liquid input port 116 of the first liquid storage container 110.

The reaction vessel may be provided with electrochemical reaction elements (anode plates, cathode plates, etc.) and may also store an electrolyte, such as sodium hydroxide solution, etc. The anode plate and the cathode plate are respectively immersed in the electrolyte.

When the electrolytic oxygen removing device 20 is installed to the refrigerator 1, the cathode plate may be in air flow communication with the storage compartment of the refrigerator 1. And the cathode plate is used to consume oxygen in the storage compartment through an electrochemical reaction when energized. For example, oxygen in the air may undergo a reduction reaction at the cathode plate, namely: o (O) ₂ +2H ₂ O+4e ^- →4OH ^- 。

The anode plate and the cathode plate are disposed in the reaction vessel 500 at a distance from each other. And when energized, the anode plate serves to provide reactants (e.g., electrons) to the cathode and generate oxygen through an electrochemical reaction. OH generated by cathode plate ^- An oxidation reaction may occur at the anode plate and oxygen may be generated, namely: 4OH ^- →O ₂ +2H ₂ O+4e ^- . Oxygen may be vented through vent 201 in the reaction vessel.

The oxygen generated in the reaction vessel enters the first air duct and is recovered by one-time filtration 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 vent hole may still carry electrolyte, and by making it enter the second air duct and be filtered and recovered again in the second filter housing 220, the electrolyte carried by the oxygen can be dissolved continuously, thereby improving the filtering and recovering efficiency.

After secondary filtration, the electrolyte content carried by the oxygen flowing out of the second vent hole is very small, and the oxygen has been reduced to a point where the user can contact, and the electrolyte content dissolved in the second filter housing 220 is also very small, so that when the user performs liquid adding to the second liquid storage container 210, or when the user observes bubbles through the second liquid storage container 210 and the second filter housing 220, safety can be ensured, and a non-professional can conveniently perform the liquid adding process.

Since the reaction vessel is provided with the fluid infusion port 202, the fluid supply port 114 of the first fluid reservoir 110 is communicated with the fluid infusion port 202 of the reaction vessel, so that the fluid in the first fluid reservoir 110 sequentially flows through the fluid supply port 114 and the fluid infusion port 202 to enter the reaction vessel. Another liquid level switch 300 may be disposed in the reaction vessel, for automatically opening and closing the liquid supplementing port 202 according to the liquid level in the reaction vessel, and the structure of the liquid level switch 300 is the same as that of the liquid level switch 300 in the above embodiment, and will not be described herein.

In this embodiment, since the electrochemical reaction of the electrolytic oxygen removing device 20 consumes water, the liquid in the first liquid storage container 110, the first filter housing 120, the second liquid storage container 210 and the second filter housing 220 may be directly water or may be converted into an electrolyte with a low concentration.
