In this embodiment, the moisture permeable film 541 may be a one-way pervaporation film having a hydrophilic layer and a hydrophobic layer, one side of the hydrophilic layer facing away from the hydrophobic layer is exposed in the storage container 200, i.e. faces towards the inside of the storage container 200, one side of the hydrophobic layer facing away from the hydrophilic layer faces away from the inside of the storage container 200, and water vapor in the storage container 200 can permeate through the moisture permeable film 541 and enter the fan housing 530. The moisture permeable film 541 allows water vapor to pass therethrough, and also blocks other gases from passing therethrough, thereby preventing gas exchange between the inside of the container 200 and the inside of the hood 530.

The shape of the moisture permeable film 541 is matched with the shape of the opening, so that the opening can be just closed, a closed space formed by the moisture permeable film 541 and the fan housing 530 can only allow water vapor in the storage container 200 to enter the fan housing 530 in a single direction, gas exchange between the inside of the fan housing 530 and the inside of the storage container 200 can be blocked, oxygen generated on the second electrolytic part 521 can be prevented from entering the storage container 200, the storage container 200 can be kept in a relatively closed state, a good fresh-keeping atmosphere can be maintained, and the fresh-keeping effect can be improved.

The two moisture permeable plates 542 are respectively attached to the bottom and the top of the moisture permeable film 541, and the moisture permeable plates 542 are used for supporting and fixing the moisture permeable film 541, so that the moisture permeable film 541 can be prevented from being deformed due to the influence of gravity or mechanical vibration and other factors. If the moisture permeable film 541 deforms, a gap may be formed between the moisture permeable film 541 and the periphery of the opening, so that a closed space cannot be formed between the moisture permeable film 541 and the fan housing 530, and the fresh-keeping effect of the storage container 200 is reduced. The moisture permeable plate 542 is also provided with through holes arranged in an array, and the through holes are configured to allow the gas in the storage container 200 to pass through.

The hood 530 is disposed around the second electrolytic portion 521, and the moisture permeable film set 540 is disposed at an opening of the hood 530, so as to allow the water vapor in the container 200 to enter the hood 530, thereby allowing the hood 530 to communicate with the environment outside the container 200, and allowing the water vapor in the container 200 to be discharged to the outside of the container 200 through the hood 530. The second electrolytic fan is arranged on one side of the second electrolytic part 521 facing the inside of the storage container 200, so that the gas flow rate in the storage container 200 can be increased, the probability of contact between the water vapor in the storage container 200 and the moisture permeable film group 540 is increased, the moisture permeable efficiency of the moisture permeable film group 540 is increased, and the water vapor reduction rate in the storage container 200 is increased. On this basis, in the embodiment, the second modified atmosphere module 520 is configured to be opened when the humidity in the storage container 200 is greater than the first preset humidity threshold, and the electrochemical reaction of the second electrolysis part 521 can be utilized to consume the water vapor in the storage container 200, so that the rate of reducing the water vapor in the storage container 200 is further increased, the reasonable humidity range inside the storage container 200 can be rapidly restored, and the dry storage environment inside the storage container 200 can be rapidly realized.

Because the second electrolysis part 521 is located inside the air cover 530 and the opening of the air cover 530 is sealed by the one-way moisture permeable film 541, oxygen generated by the second electrolysis part 521 through electrochemical reaction cannot enter the storage container 200, which is beneficial to maintaining a low-oxygen fresh-keeping atmosphere inside the storage container 200 and avoiding the influence of the start-up operation of the second modified atmosphere module 520 on the oxygen concentration inside the storage container 200.

In this embodiment, oxygen generated at the second electrolytic part 521 may be discharged to the outside of the storage container 200 through the oxygen delivery passage. The hood 530 may have an oxygen supply passage therein, which communicates with the outside of the container 200 and guides the gas in the hood 530 to the outside of the container 200. The oxygen supply passage may be an air tube communicating with the environment outside the storage container 200, and the oxygen in the hood 530 may be discharged to the outside of the storage container 200 through the air tube. The area of the projection of the hood 530 on the top wall surface of the storage container 200 may be larger than the area of the second air permeable region 212, so that when the hood 530 is disposed around the outer periphery of the second modified atmosphere module 520, the projection of the hood 530 on the top wall surface of the storage container 200 coincides with a portion of the non-air permeable region, and the air tube may be disposed through the portion of the non-air permeable region.

In other alternative embodiments, oxygen generated on the second electrolytic part 521 may also be discharged to the outside of the storage container 200 through the through hole. For example, the second modified atmosphere module 520 may be provided with through holes arranged in an array to allow oxygen generated in the second electrolytic part 521 to be discharged to the outside of the storage container 200. The second electrolytic portion 521 and the second oxygen consuming portion 522 may be porous flat electrodes, and the second proton exchange membrane may be a porous proton exchange membrane. The second atmosphere control module 520 is provided with through holes arranged in an array, so that the second electrolysis part 521 of the second atmosphere control module 520 is directly communicated with the external environment of the storage container 200, the electrode roughness of the second electrolysis part 521 and the second oxygen consumption part 522 is increased, and the electrochemical reaction efficiency of the second atmosphere control module 520 is improved.

In other alternative embodiments, oxygen generated on the second electrolytic part 521 may also be discharged to the outside of the storage container 200 through the second gas permeable area 212. For example, the second modified atmosphere module 520 may have a smaller outer shape than the second air-permeable region 212, and the projected area of the second modified atmosphere module 520 on the top wall surface of the storage container 200 may be smaller than the area of the second air-permeable region 212, so that the second modified atmosphere module 520 partially shields the second air-permeable region 212; the projected area of the hood 530 on the top wall surface of the storage container 200 may be larger than the area of the second air-permeable region 212, so that the hood 530 completely shields the second air-permeable region 212. So set up, fan housing 530 can be through second ventilative regional 212 and storage container 200 external environment intercommunication, and the oxygen in fan housing 530 can directly pass through second ventilative regional 212 and arrange to the storage container 200 outside, and simple structure need not to add other devices.

The cover plate 700, which forms an upper cover of the storage device, is configured to cover the storage container 200 to make the outer shape neat. The cover panel 700 includes a top cover portion covering the top surface of the storage container 200 and extending along the rear surface of the storage container 200 to form a connecting portion for being fixedly connected to the storage container 200, and a connecting portion. The top cover portion also has through holes (not shown) arranged in an array to allow gas to pass through. The connecting portion is provided with a plurality of clamping grooves configured to be clamped with the fasteners on the back of the storage container 200 to fix the cover plate 700.

The refrigerator 10 may further include: the oxygen concentration sensor 400 is disposed in the storage container 200 and configured to detect the oxygen concentration in the storage container 200 every first predetermined time after the storage container 200 is closed.

After the storage container 200 is opened, gas exchange will occur with the air in the external environment, resulting in the increase of the oxygen concentration inside the storage container 200, and therefore, after the storage container 200 is closed, it is generally necessary to determine whether oxygen needs to be removed again according to the actual oxygen concentration, so as to create a low-oxygen fresh-keeping atmosphere again.

The first air-conditioning module 510 is configured to be powered on when the oxygen concentration in the storage container 200 is greater than a preset oxygen concentration threshold.

That is, when the oxygen concentration in the storage container 200 exceeds the preset oxygen concentration threshold, the oxygen concentration is high, and the oxygen concentration in the storage container 200 needs to be reduced by the first air-conditioning module 510; after the first air-conditioning module 510 is turned on, the first electrolysis fan 551 is turned on. The first electrolysis fan 551 is opened and closed along with the opening and closing of the first controlled atmosphere module 510.

The first air conditioning module 510 is shut down when its operating time period is greater than or equal to a preset operating time period.

During operation of the first modified atmosphere module 510, since the storage container 200 is relatively closed, the oxygen content will continue to decrease, resulting in a decrease in the concentration of the reactant for the electrochemical reaction performed by the first modified atmosphere module 510, and accordingly, the efficiency of the electrochemical reaction will decrease or even no electrochemical reaction will occur at all. When the operation time of the first air conditioning module 510 is longer than or equal to the preset operation time, it means that the electrolysis efficiency of the first air conditioning module 510 is already low, and the electrochemical reaction of the first air conditioning module 510 needs to be terminated, so as to avoid wasting too much electric energy and compromising the life of the first air conditioning module 510.

The preset working time of the first modified atmosphere module 510 can be set according to actual requirements, and in the preset working time, the oxygen concentration in the storage container 200 can be reduced to be lower than a preset reasonable concentration threshold value, and the preset reasonable concentration threshold value is smaller than the preset oxygen concentration threshold value.

The humidity sensor 300 is disposed in the storage container 200 and configured to detect humidity in the storage container 200. In this embodiment, the humidity sensor 300 may detect the humidity inside the storage container 200 every second preset time when the first air-conditioning module 510 operates.

The first oxygen consumption part 512 of the first air conditioning module 510 generates water by using oxygen and hydrogen ions as reactants during an electrochemical reaction, which may cause the concentration of water vapor in the container 200 to increase. If too much vapor is detained in the storage container 200 and can lead to condensation or drip, therefore, need utilize humidity transducer 300 to detect the inside humidity of storage container 200 in the operation process of first modified atmosphere module 510 to adjust deoxidization process and dehumidification process according to the humidity value correspondingly, make the storage container 200 reduce or avoid inside condensation or drip phenomenon to take place when obtaining better deoxidization effect.

The second modified atmosphere module 520 is configured to be powered on when the humidity in the storage container 200 is greater than a first predetermined humidity threshold, and is further configured to be powered off when the humidity in the storage container 200 is less than a second predetermined humidity threshold, the first predetermined humidity threshold being greater than the second predetermined humidity threshold.

When the humidity in the storage container 200 is greater than the first preset humidity threshold, the humidity in the storage container 200 is higher, the risk of condensation is higher, the humidity in the storage container 200 cannot be rapidly reduced by the conventional moisture permeable function of the moisture permeable membrane set 540 alone, and the electrochemical reaction of the second air conditioning module 520 needs to be started for rapid dehumidification, in this embodiment, the second electrolytic fan and the second air conditioning module 520 can be started simultaneously. In other alternative embodiments, the second electrolysis fan may also be activated before the second air-conditioning module 520 is activated, and the activation of the second electrolysis fan can improve the moisture permeation efficiency of the moisture permeable film set 540, for example, the second electrolysis fan may also be activated when the humidity inside the storage container 200 is greater than a third preset humidity threshold, wherein the third preset humidity threshold is smaller than the first preset humidity threshold and greater than the second preset humidity threshold, so as to improve the moisture permeation efficiency of the moisture permeable film 541.

When the humidity in the storage container 200 is smaller than the second preset humidity threshold value, the humidity in the storage container 200 is reduced, the risk of condensation is low, the humidity in the storage container 200 can be kept in a reasonable range by the conventional moisture permeable function of the moisture permeable membrane group 540 alone, and the electrochemical reaction of the second air conditioning module 520 does not need to be started for rapid dehumidification; accordingly, the second electrolytic fan does not need to be started. When the humidity in the storage container 200 is less than the second preset humidity threshold, the second modified atmosphere module 520 is stopped, and the second electrolysis fan is stopped. In other alternative embodiments, the second electrolytic air blower may also continue to operate after the second modified atmosphere module 520 is shut down under the conditions of operation of the first modified atmosphere module 510 to improve the moisture permeation efficiency of the moisture permeable film 541.

In step S1102, the oxygen concentration detected by the oxygen concentration sensor 400 is acquired.

Step S1104, determining whether the oxygen concentration is greater than a preset oxygen concentration threshold, if so, performing step S1106, which means that the oxygen concentration is higher, and the first controlled atmosphere module 510 needs to be started to remove oxygen from the storage container 200; if not, the process returns to step S1102.

In step S1106, the first air-conditioning module 510 is turned on, and the first electrolysis fan 551 is turned on. The first electrolysis fan 551 facilitates the airflow outside the storage container 200 to flow to the first electrolysis part 511 of the first air conditioning module 510, so as to supplement the water vapor required for the electrochemical reaction to the first electrolysis part 511, accelerate the electrochemical reaction rate, and improve the oxygen removal efficiency of the first air conditioning module 510.

In step S1108, the humidity detected by the humidity sensor 300 is acquired. The humidity within the storage container 200 is monitored while the first modified atmosphere module 510 is operating to facilitate timely humidity regulation.

Step S1110, determining whether the humidity is greater than a first preset humidity threshold, if so, performing step S1124, which means that the humidity in the storage container 200 is higher, and the humidity in the storage container 200 cannot be rapidly reduced simply by the conventional moisture permeable function of the moisture permeable membrane set 540, and the second air-conditioning module 520 needs to be started to rapidly dehumidify the interior of the storage container 200; if not, go to step S1112. In the rapid dehumidification function mode, the second controlled atmosphere module 520 and the second electrolysis fan operate simultaneously, so that the concentration of the water vapor in the storage container 200 can be rapidly reduced.

Step S1112, determining whether the humidity is greater than a third preset humidity threshold, if so, executing step S1114, which means that the humidity in the storage container 200 is higher, and the second electrolytic fan needs to be used to improve the moisture permeation efficiency of the moisture permeable film 541 so as to accelerate the humidity reduction rate in the storage container 200; if not, the process returns to step S1118.

Step S1114, the second electrolytic fan is turned on. After the second electrolytic fan is started, airflow flowing through the moisture permeable membrane set 540 is formed in the storage container 200, and the water vapor permeation efficiency in the storage container 200 is improved.

Step S1118, the second electrolysis fan is stopped.

In step S1120, it is determined whether the shutdown condition of the first modified atmosphere module 510 is met, that is, whether the operation time of the first modified atmosphere module 510 is longer than or equal to the preset operation time is determined, if yes, step S1122 is executed, if no, step S1108 is executed again, and the humidity in the storage container 200 is continuously monitored.

In step S1122, the first air conditioning module 510 is stopped, and the first electrolysis fan 551 is stopped. Under the condition that the storage container 200 is kept in a closed state, when the working time of the first air-conditioning module 510 is longer than or equal to the preset working time, the oxygen concentration in the storage container 200 can be reduced to be below a preset reasonable concentration threshold value, and in order to avoid consuming too much electric energy, the first air-conditioning module 510 and the first electrolysis fan 551 are shut down.

In step S1124, the quick dehumidification function is turned on. The second modified atmosphere module 520 and the second electrolysis fan are operated simultaneously. The second electrolytic fan causes the air flow in the storage container 200 to enter the fan housing 530 through the moisture permeable membrane set 540 and blow to the second electrolytic part 521, the second electrolytic part 521 performs an electrochemical reaction by using the water vapor from the storage container 200 as a reactant, so that the consumption of the water vapor in the storage container 200 is accelerated, the concentration reduction rate of the water vapor in the storage container 200 is improved, the storage container 200 is quickly restored to a reasonable humidity range, and condensation or dripping is prevented.

Step S1126, judging whether the closing condition of the quick dehumidification function is reached, namely judging whether the humidity in the storage container 200 is smaller than a second preset humidity threshold value, if so, executing step S1128; if not, the process returns to step S1126, and the humidity in the storage container 200 continues to be monitored.

Step S1128, the quick dehumidification function is turned off. The second controlled atmosphere module 520 is shut down and the second electrolysis fan is shut down.

Step S1130, determining whether the shutdown condition of the first modified atmosphere module 510 is met, that is, determining whether the operation duration of the first modified atmosphere module 510 is greater than or equal to the preset operation duration, if so, performing step S1132, otherwise, returning to step S1108, and continuing to monitor the humidity in the storage container 200.

In step S1132, the first air-conditioning module 510 is stopped, and the first electrolysis fan 551 is stopped.

Specifically, when the atmosphere control module is operated, if the storage container 200 is opened, the first atmosphere control module 510, the second atmosphere control module 520, the first electrolytic fan 551, and the second electrolytic fan are stopped or maintained in a stopped state, and after the storage container 200 is closed, whether to start the atmosphere control module is determined again according to the oxygen concentration and humidity in the storage container 200.

In the refrigerator 10 of this embodiment, the first oxygen consumption part 512 of the first air conditioning module 510 also generates water while consuming oxygen, when the humidity in the storage container 200 is greater than the first preset humidity threshold, the second air conditioning module 520 is turned on and consumes the water vapor in the storage container 200 through the electrochemical reaction, so as to improve the rate of reducing the water vapor in the storage container 200, thereby facilitating the rapid restoration of the interior of the storage container 200 to a reasonable humidity range, and further reducing or avoiding the occurrence of internal condensation or water dripping when the storage container 200 obtains a better oxygen removal effect.
