[0001] This invention relates to the field of home appliance technology, and in particular to a control method for an oxygen regulation module and a refrigerator having the oxygen regulation module. Background Technology

[0002] Currently, refrigerators have increasingly stringent requirements for preserving high-end foods. Some foods require storage in low-oxygen or high-oxygen environments. This is achieved by installing an oxygen-regulating module inside the refrigerator to control the oxygen content within the compartment. As the operating time increases, the temperature of the oxygen-regulating module rises, its resistance decreases, and the current increases. To avoid excessive current affecting the power supply load, the oxygen-regulating module needs to be controlled.

[0003] In view of this, it is necessary to provide a control method for an oxygen regulation module and a refrigerator having the oxygen regulation module to solve the above-mentioned technical problems. Summary of the Invention

[0019] If the sum of the real-time currents is greater than the preset range, reduce the current voltage of the oxygen adjustment module until the sum of the real-time currents is within the preset range; or reduce the current voltage of the oxygen adjustment module by a preset change value.

[0020] As a further improvement of the present invention, the step of "adjusting the voltage of the oxygen regulating module so that the sum of the real-time currents is not greater than a preset range" also includes:

[0021] If the sum of the real-time currents is less than the preset range, increase the current voltage of the oxygen adjustment module until the sum of the real-time currents is within the preset range; or increase the current voltage of the oxygen adjustment module by a preset change value.

[0054] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0055] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0056] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0057] In the description of this invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection" and "linking" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0058] like Figures 1 to 4 The diagram shown is a partial structural schematic of the refrigerator provided by the present invention, which includes an oxygen regulation module 100, a compartment 200, a control device 300, and a current detection device 400.

[0059] The oxygen regulation module 100 is used to perform an electrochemical reaction and prepare oxygen-regulated gas. The chamber 200 is connected to the oxygen regulation module 100 and receives the oxygen-regulated gas prepared by the oxygen regulation module 100. The control device 300 is used to adjust the operating voltage of the oxygen regulation module 100. The current detection device 400 is used to detect the real-time current in the circuit and transmit it to the control device 300, which adjusts the current voltage of the oxygen regulation module 100 according to the real-time current.

[0060] The oxygen regulation module 100 includes an electrolyte storage chamber 101, a first electrode 102 and a second electrode 103 located on opposite sides of the electrolyte storage chamber 101. The first electrode 102 and the second electrode 103 are respectively connected to the anode and cathode of the power supply, and after being energized, the first electrode 102 and the second electrode 103 respectively generate oxygen-regulated gas.

[0061] After being energized, oxygen reaches the surface of the first electrode 102 connected to the cathode of the power supply. Under the action of the DC electric field, an oxygen dissolution reaction occurs on the surface of the first electrode 102, and then a reverse reaction occurs on the second electrode 103 connected to the anode of the power supply to produce pure oxygen. By introducing the oxygen-regulating gas prepared by the oxygen-regulating module 100 into the chamber 200 connected to the oxygen-regulating module 100, the oxygen content in the chamber 200 can be increased or decreased.

[0062] In this embodiment, the chamber 200 receives oxygen-regulating gas from the first electrode 102 to reduce the oxygen content within the chamber 200. The second electrode 103 is located outside the chamber 200.

[0063] A connecting cavity 500 is provided between the oxygen regulating module 100 and the compartment 200, and the oxygen regulating module 100 and the compartment 200 are connected through the connecting cavity 500.

[0064] The connecting cavity 500 includes an inlet pipe and an outlet pipe communicating with the chamber 200. Air from the chamber 200 flows into the connecting cavity 500 through the inlet pipe. Oxygen in the air flowing into the connecting cavity 500 participates in a reduction reaction at the position of the first electrode 102, thereby reducing the oxygen content in the connecting cavity 500. The low-oxygen air from the connecting cavity 500 then flows into the chamber 200 through the outlet pipe, thereby reducing the oxygen content in the chamber 200.

[0065] Of course, in other embodiments, the first electrode 101 can also be placed directly inside the chamber 200. Oxygen in the chamber 200 participates in a reduction reaction at the location of the first electrode 101, thereby gradually consuming the oxygen in the chamber 200. Meanwhile, the second electrode 102, located outside the chamber 200, undergoes an oxidation reaction to generate oxygen.

[0066] Because the oxygen regulation module 100 generates a large amount of heat during operation, its temperature rises and its resistance decreases as the operating time increases, leading to an increase in the current. To prevent excessive current from affecting the normal operation of the oxygen regulation module 100 or even damaging it, the current detection device 400 periodically collects real-time current data and transmits it to the control device 500. The control device 500 adjusts the voltage of the oxygen regulation module 100 based on the real-time current, thereby ensuring that the oxygen regulation module 100 operates with a suitable current and preventing excessive current.

[0067] The current detection device 400 can be used to detect the real-time current of the oxygen regulation module 100 independently and transmit the detected real-time current to the control device 300. The current detection device 400 can also be used to detect the sum of the real-time currents of the oxygen regulation module 100 and the control device 300, and transmit the sum of the detected real-time currents to the control device 300. The control device 300 adjusts the voltage of the oxygen regulation module 100 based on the real-time current of the oxygen regulation module 100 or the sum of the real-time currents of the oxygen regulation module 100 and the control device 300, thereby ensuring that the oxygen regulation module 100 operates with an appropriate current and avoiding excessive current in the oxygen regulation module 100.

[0068] Reference Figures 5 to 9 The present invention also provides a control method for an oxygen regulation module.

[0069] Reference Figure 5 , Figure 6 and Figure 9 In Example 1, the current detection device 400 detects the real-time current of the oxygen regulation module 100 and adjusts the voltage of the oxygen regulation module 100 based on the real-time current of the oxygen regulation module 100.

[0070] The control method includes the following steps:

[0071] Step 1: Turn on the oxygen adjustment module 100;

[0072] Step 2: Collect the real-time current of the oxygen regulation module 100;

[0073] Step 3: Based on the real-time current, adjust the voltage of the oxygen regulation module 100 so that the real-time current does not exceed a preset range.

[0074] In step 1, when it is necessary to adjust the oxygen content in the chamber 200, the oxygen adjustment module 100 is turned on to prepare oxygen-adjusted gas and the oxygen-adjusted gas is delivered into the chamber 200.

[0075] Specifically, the need to activate the oxygen regulating module 100 can be determined by monitoring the oxygen content within the chamber 200; or the oxygen regulating module 100 can be activated at set intervals to adjust the oxygen content within the chamber 200. Preferably, the oxygen regulating module 100 is activated after the chamber 200 has finished cooling to perform oxygen regulation. This ensures that the temperature within the chamber 200 is at its lowest at this time, and also avoids the impact of the oxygen regulating module 100's operation on the cooling of the chamber 200.

[0076] When it is necessary to turn on the oxygen regulation module 100, the oxygen regulation module 100 is turned on by the control device 300 with a preset voltage.

[0077] In step 2, the current detection device 400 detects the real-time current of the oxygen regulation module 100, and the current detection device 400 transmits the detected real-time current to the control device 300.

[0078] In step 3, based on the real-time current, the voltage of the oxygen regulation module 100 is adjusted by the control device 300. This ensures that the oxygen regulation module 100 operates with a suitable current, preventing the current of the oxygen regulation module 100 from becoming too high.

[0079] The phrase "adjusting the voltage of the oxygen regulation module 100 so that the real-time current does not exceed a preset range" includes:

[0080] If the real-time current is within a preset range, the oxygen regulation module 100 is controlled to continue operating at the current voltage.

[0081] If the real-time current is greater than the preset range, reduce the current voltage of the oxygen adjustment module 100 until the real-time current is within the preset range; or reduce the current voltage of the oxygen adjustment module 100 by a preset change value.

[0082] When the real-time current I detected by the current detection device 400 is within a preset range, i.e. I1≤I≤I2, the current of the oxygen regulation module 100 is within a suitable range, and there is no need to adjust the voltage of the oxygen regulation module 100 through the control device 300, so the oxygen regulation module 100 can continue to operate at the current voltage.

[0083] When the real-time current I detected by the current detection device 400 is greater than the maximum value of the preset range, i.e., I > I², the current of the oxygen regulation module 100 exceeds the preset range. To prevent the excessive current of the oxygen regulation module 100 from affecting its normal operation, the control device 300 reduces the preset change value of the current voltage of the oxygen regulation module 100, thereby reducing the current of the oxygen regulation module 100. Alternatively, the current voltage is reduced until the real-time current is less than or equal to the maximum value of the preset range, ensuring that the oxygen regulation module 100 operates with a suitable current and avoiding excessive current.

[0084] Specifically, the step of "reducing the current voltage of the oxygen regulation module 100 by a preset change value" includes:

[0085] Obtain the module temperature of the oxygen regulation module 100;

[0086] Calculate the temperature change of the oxygen regulation module 100 within a first preset time period;

[0087] Determine whether the temperature change of the module is greater than the first speed threshold.

[0088] If so, reduce the current voltage of the oxygen regulation module 100 by a first preset change value;

[0089] If not, reduce the current voltage of the oxygen regulation module 100 by a second preset change value;

[0090] Among them, the first preset change value is greater than the second preset change value.

[0091] The temperature of the oxygen-regulating module 100 is detected by a temperature sensor, and the temperature change of the oxygen-regulating module 100 within a first preset time period is calculated to obtain the heating rate of the oxygen-regulating module 100. When the module temperature change is greater than a first rate threshold, the current voltage of the oxygen-regulating module 100 is reduced by a first preset change value; when the module temperature change is less than or equal to the first rate threshold, the current voltage of the oxygen-regulating module 100 is reduced by a second preset change value. The first preset change value is greater than the second preset change value.

[0092] When the module temperature change exceeds the first speed threshold, it indicates that the oxygen regulation module 100 is heating up rapidly, significantly impacting its current. This causes the current voltage of the oxygen regulation module 100 to decrease by a first preset change value, preventing overcurrent. When the module temperature change is less than or equal to the first speed threshold, it indicates that the oxygen regulation module 100 is heating up slowly, having a smaller impact on its current. This causes the current voltage of the oxygen regulation module 100 to decrease by a second preset change value, ensuring the oxygen regulation efficiency of the oxygen regulation module 100.

[0093] The first preset change value and the second preset change value can be adjusted according to the power adaptability of the oxygen adjustment module 100.

[0094] The phrase "adjusting the voltage of the oxygen regulation module 100 so that the real-time current does not exceed a preset range" further includes:

[0095] If the real-time current is less than the preset range, increase the current voltage of the oxygen regulation module 100 until the real-time current is within the preset range; or increase the current voltage of the oxygen regulation module 100 by a preset change value.

[0096] When the real-time current I detected by the current detection device 400 is less than the minimum value of the preset range, i.e., I < I1, the current of the oxygen regulation module 100 is lower than the preset range. At this time, the current of the oxygen regulation module 100 is too low, affecting its oxygen regulation efficiency in the compartment 200. The control device 300 increases the preset change value of the current voltage of the oxygen regulation module 100. Alternatively, it increases the current voltage until the real-time current is greater than or equal to the minimum value of the preset range, thereby increasing the current of the oxygen regulation module 100, ensuring that the oxygen regulation module 100 operates with an appropriate current, and avoiding excessively low current.

[0097] Specifically, the step of "increasing the current voltage of the oxygen regulation module 100 by a preset change value" includes:

[0098] Obtain the module temperature of the oxygen regulation module 100;

[0099] Calculate the temperature change of the oxygen regulation module 100 within a second preset time period;

[0100] Determine whether the temperature change of the module is greater than the second speed threshold.

[0101] If so, increase the current voltage of the oxygen regulation module 100 by a third preset change value;

[0102] If not, increase the current voltage of the oxygen regulation module 100 by a fourth preset change value;

[0103] Among them, the third preset change value is less than the fourth preset change value.

[0104] The temperature of the oxygen-regulating module 100 is detected by a temperature sensor, and the temperature change of the oxygen-regulating module 100 within a second preset time period is calculated to obtain the heating rate of the oxygen-regulating module 100. When the module temperature change is greater than a second rate threshold, the current voltage of the oxygen-regulating module 100 is increased by a third preset change value; when the module temperature change is less than or equal to the second rate threshold, the current voltage of the oxygen-regulating module 100 is increased by a fourth preset change value. The third preset change value is less than the fourth preset change value.

[0105] When the module temperature change exceeds the first speed threshold, it indicates that the oxygen regulation module 100 is heating up rapidly, significantly impacting its current. Therefore, the current voltage of the oxygen regulation module 100 is increased by a third preset change value to prevent overcurrent. When the module temperature change is less than or equal to the first speed threshold, it indicates that the oxygen regulation module 100 is heating up slowly, with minimal impact on its current. Therefore, the current voltage of the oxygen regulation module 100 is increased by a fourth preset change value to ensure its oxygen regulation efficiency.

[0106] The third and fourth preset change values ​​can be adjusted according to the power adaptability of the oxygen adjustment module 100.

[0107] It is understood that by periodically collecting the real-time current I detected by the oxygen regulation module 100 and transmitting it to the control device 300, the voltage of the oxygen regulation module 100 is adjusted according to the real-time current I at set intervals, thereby regulating the real-time current I of the oxygen regulation module 100. By dynamically adjusting the real-time current I of the oxygen regulation module 100, firstly, it is possible to effectively prevent the generation of large currents that could affect the normal operation of the oxygen regulation module 100; secondly, it is possible to improve the oxygen regulation efficiency of the oxygen regulation module 100.

[0108] The actual voltage value of the adjusted oxygen regulating module 100 is compared with the output voltage value of the control device 300 to determine whether they match. If the difference between the actual voltage value of the oxygen regulating module 100 and the output voltage value of the control device 300 is greater than a set value, the oxygen regulating module 100 is determined to be abnormal and is shut down.

[0109] During the adjustment of the voltage of the oxygen regulation module 100, the ratio of the voltage of the oxygen regulation module 100 to the real-time current I is also calculated.

[0110] Determine whether the ratio is greater than a first threshold.

[0111] If so, turn off the oxygen regulation module 100 and add electrolyte into the oxygen regulation module 100;

[0112] If not, the oxygen regulation module 100 continues to operate.

[0113] During the operation of the oxygen regulation module 100, the electrolyte in the electrolyte storage chamber 101 is continuously consumed. As the electrolyte is consumed, the resistance of the oxygen regulation module 100 continuously increases, causing the current of the oxygen regulation module 100 to decrease, thus affecting the oxygen regulation efficiency of the oxygen regulation module 100. When the ratio is greater than the first threshold, it indicates that the electrolyte level in the electrolyte storage chamber 101 is low, and electrolyte needs to be added to the electrolyte storage chamber 101.

[0114] In this embodiment, the resistance value of the oxygen regulation module 100 measured when the electrolyte in the electrolyte storage cavity 101 is 1 / 3 to 1 / 4 full can be used as the first threshold.

[0115] In some embodiments of the present invention, the method further includes determining whether the ratio is less than a third threshold. If so, a short circuit risk is identified, the operation of the oxygen regulation module 100 is immediately stopped, and an alarm is issued. If not, the oxygen regulation module 100 continues to operate. To avoid the excessive heat generated by the prolonged operation of the oxygen regulation module 100 affecting the temperature inside the chamber 200, the oxygen regulation module 100 operates intermittently.

[0116] The continuous running time of the oxygen regulation module 100 is obtained, and it is determined whether the continuous running time has reached the third preset time. If not, the oxygen regulation module 100 continues to run; if so, the oxygen regulation module 100 is turned off, and the oxygen regulation module 100 is turned on again after the fourth preset time.

[0117] The oxygen adjustment module 100 is activated by the control device 300 to adjust the oxygen level. After the oxygen adjustment module 100 operates continuously for a third preset time T1, it is turned off. After waiting for a fourth preset time T2, the oxygen adjustment module 100 is activated again, and this process is repeated. Simultaneously, the cumulative activation time of the oxygen adjustment module 100 is calculated. When the cumulative activation time reaches a preset time, the oxygen adjustment operation of the oxygen adjustment module 100 ends, and the system waits for the next oxygen adjustment cycle. Preferably, the voltage at which the oxygen adjustment module 100 is activated is a preset voltage, which is less than or equal to the rated voltage of the oxygen adjustment module 100.

[0118] In one specific embodiment, the control device 300 turns on the oxygen adjustment module 100 with a rated voltage, and at the same time, the current detection device 400 detects the real-time current I of the oxygen adjustment module 100.

[0119] When the oxygen regulating module 100 is turned on at the rated voltage, the oxygen regulating efficiency of the oxygen regulating module 100 can be improved, and it is only necessary to prevent the current of the oxygen regulating module 100 from being too high.

[0120] When the real-time current I detected by the current detection device 400 is less than or equal to the maximum value of the preset range, i.e., I ≤ I2, the current of the oxygen adjustment module 100 is within a suitable range, and there is no need to adjust the voltage of the oxygen adjustment module 100 through the control device 300. When the real-time current I detected by the current detection device 400 is greater than the maximum value of the preset range, i.e., I > I2, the control device 300 reduces the current of the oxygen adjustment module 100, thereby reducing the current of the oxygen adjustment module 100, until the current of the oxygen adjustment module 100 is less than or equal to the maximum value of the preset range.

[0121] At set intervals, the current detection device 400 transmits the detected real-time current I to the control device 300. The control device 300 adjusts the voltage of the oxygen regulation module 100 according to the real-time current I, thereby ensuring that the current of the oxygen regulation module 100 is always within a suitable range.

[0122] In another specific embodiment, the control device 300 turns on the oxygen adjustment module 100 with a voltage less than the rated voltage, and at the same time detects the real-time current I through the current detection device 400.

[0123] When the oxygen regulating module 100 is turned on at a voltage lower than the rated voltage, the voltage of the oxygen regulating module 100 is gradually adjusted according to the current feedback of the current detection device 400, which can reduce the current surge during initial power-on.

[0124] When the real-time current I is within a preset range, i.e., I1≤I≤I2, the current voltage of the oxygen regulating module 100 remains unchanged. When the real-time current I detected by the current detection device 400 is greater than the maximum value of the preset range, i.e., I>I2, the current of the oxygen regulating module 100 exceeds the preset range, and the control device 300 reduces the preset change value of the current voltage of the oxygen regulating module 100. When the real-time current I detected by the current detection device 400 is less than the minimum value of the preset range, i.e., I1≤I≤I2, the current of the oxygen regulating module 100 exceeds the preset range. ＜ I1, if the current of the oxygen regulation module 100 is lower than the preset range, the control device 300 increases the preset change value of the current voltage of the oxygen regulation module 100.

[0125] At set intervals, the current detection device 400 transmits the detected real-time current I to the control device 300. The control device 300 adjusts the voltage of the oxygen regulation module 100 according to the real-time current I, thereby ensuring that the current of the oxygen regulation module 100 is always within a suitable range.

[0126] In this embodiment, it is also included to determine whether the current voltage of the oxygen regulation module 100 has reached the maximum set value. If so, the voltage is maintained at the maximum set value; if not, the voltage value is increased.

[0127] If, during the gradual increase of the voltage of the oxygen regulating module 100, the real-time current I remains less than the minimum value of the preset range until the voltage reaches the maximum set value, then the voltage of the oxygen regulating module 100 will no longer be increased, and the voltage will remain at the maximum set value. The maximum set value is the rated voltage.

[0128] Reference Figures 7 to 9Example 2 differs from Example 1 only in that: the current detection device 400 detects the sum of the real-time currents of the oxygen regulation module 100 and the control device 300, and adjusts the voltage of the oxygen regulation module 100 based on the sum of the real-time currents.

[0129] The control method includes the following steps:

[0130] Activate oxygen regulation module 100;

[0131] The sum of the real-time current of the control device 300 used to adjust the voltage of the oxygen adjustment module 100 and the real-time current of the oxygen adjustment module 100 is obtained.

[0132] Based on the sum of the real-time currents, the voltage of the oxygen regulation module 100 is adjusted so that the sum of the real-time currents does not exceed a preset range.

[0133] The phrase "adjusting the voltage of the oxygen regulation module 100 so that the sum of the real-time currents is not greater than a preset range" includes:

[0134] If the sum of the real-time currents is within a preset range, the oxygen regulation module 100 is controlled to continue operating at the current voltage;

[0135] If the sum of the real-time currents is greater than the preset range, reduce the current voltage of the oxygen regulation module 100 until the sum of the real-time currents is within the preset range; or reduce the current voltage of the oxygen regulation module 100 by a preset change value.

[0136] When the sum of the real-time currents detected by the current detection device 400 is I 和 When it is within the preset range, i.e., I3≤I 和 If the current of the oxygen regulating module 100 is within a suitable range (≤I4), there is no need to adjust the voltage of the oxygen regulating module 100 through the control device 300, and the oxygen regulating module 100 can continue to operate at the current voltage.

[0137] When the sum of the real-time currents detected by the current detection device 400 is I 和 The maximum value greater than the preset range, i.e., I 和 >I4. To prevent excessive current in the oxygen regulation module 100 from affecting its normal operation, the control device 300 reduces the preset change value of the current voltage of the oxygen regulation module 100, thereby reducing the current of the oxygen regulation module 100. Alternatively, the current voltage can be reduced until the sum of the real-time currents I. 和 The current is less than or equal to the maximum value of the preset range, ensuring that the oxygen regulation module 100 operates with an appropriate current and avoiding excessive current in the oxygen regulation module 100.

[0138] The phrase "reducing the current voltage of the oxygen-regulating module 100 by a preset change value" also includes reducing the current voltage of the oxygen-regulating module 100 by a first preset change value or a second preset change value based on the module temperature change of the oxygen-regulating module 100. This is the same as in the previous embodiment and will not be repeated here. The phrase "adjusting the voltage of the oxygen-regulating module 100 so that the sum of the real-time currents is not greater than a preset range" also includes:

[0139] If the sum of the real-time currents is less than the preset range, increase the current voltage of the oxygen regulation module 100 until the sum of the real-time currents is within the preset range; or increase the current voltage of the oxygen regulation module 100 by a preset change value.

[0140] When the sum of the real-time currents detected by the current detection device 400 is I 和 The minimum value less than the preset range, i.e., I 和 <I3. At this time, the current of the oxygen regulation module 100 is too low, affecting its oxygen regulation efficiency in the compartment 200. The control device 300 increases the preset change value of the current voltage of the oxygen regulation module 100. Alternatively, the current voltage is increased until the sum of the real-time currents I. 和 The current of the oxygen regulating module 100 is increased by a value greater than or equal to the minimum value of the preset range, thereby ensuring that the oxygen regulating module 100 operates with an appropriate current and avoiding the current of the oxygen regulating module 100 being too low.

[0141] The phrase "increasing the current voltage of the oxygen regulation module 100 by a preset change value" also includes increasing the current voltage of the oxygen regulation module 100 by a third or fourth preset change value based on the module temperature change of the oxygen regulation module 100. The specific details are the same as in the previous embodiment and will not be repeated here.

[0142] During the adjustment of the voltage of the oxygen regulation module 100, the sum of the voltage of the oxygen regulation module 100 and the real-time current I is also calculated. 和 The ratio;

[0143] Determine whether the ratio is greater than the second threshold.

[0144] If so, turn off the oxygen regulation module 100 and add electrolyte into the oxygen regulation module 100;

[0145] If not, the oxygen regulation module 100 continues to operate.

[0146] During the operation of the oxygen regulation module 100, the electrolyte in the electrolyte storage chamber 101 is continuously consumed. As the electrolyte is consumed, the resistance of the oxygen regulation module 100 continuously increases, causing the current of the oxygen regulation module 100 to decrease, thus affecting the oxygen regulation efficiency of the oxygen regulation module 100. When the ratio is greater than the second threshold, it indicates that the electrolyte level in the electrolyte storage chamber 101 is low, and electrolyte needs to be added to the electrolyte storage chamber 101.

[0147] In this embodiment, the resistance value of the oxygen regulation module 100 measured when the electrolyte in the electrolyte storage cavity 101 is 1 / 3 to 1 / 4 full can be used as the second threshold.

[0148] In some embodiments of the present invention, the method further includes determining whether the ratio is less than a fourth threshold. If so, it is determined that there is a short circuit risk, the operation of the oxygen regulation module 100 is immediately stopped, and an alarm is issued. If not, the oxygen regulation module 100 continues to operate.

[0149] The control device 300 can also turn on the oxygen adjustment module 100 at the rated voltage or at a voltage lower than the rated voltage. The control method is the same as in Embodiment 1, and will not be described again here.

[0150] In summary, by periodically collecting real-time current and transmitting it to the control device 300, the control device 300 adjusts the voltage of the oxygen regulation module 100 based on the real-time current, thereby ensuring that the oxygen regulation module 100 operates with a suitable current and avoiding excessive current in the oxygen regulation module 100.
