The storage container 200 is provided in the storage compartment 111, and may be provided in any compartment as needed, and preferably, may be provided in a refrigerating compartment. The storage container 200 is a drawer, the interior of which forms a storage space 221, and the drawer includes a cylinder 210 having a front opening and a drawer body 220 drawably disposed in the cylinder 210.
The top surface of the storage container 200 is provided with a ventilation area, and gas in the storage container 200 can escape from the ventilation area. The ventilation area comprises a water removing area 212 and a oxygen removing area 211, the oxygen removing area 211 is provided with an opening and is positioned in the middle of the ventilation area, and the water removing area 212 is provided with through holes arranged in an array and is positioned on two sides of the oxygen removing area 211.
The oxygen removing assembly 300, which is disposed on the storage container 200, preferably, may be disposed on the top surface of the storage container 200, has an oxygen consuming part 320 facing the inside of the storage container 200 and serving to consume oxygen inside the storage container 200 through an electrochemical reaction, and an electrolysis part 310 facing the outside of the storage container 200 and serving to electrolyze water vapor outside the storage container 200 through an electrochemical reaction.
In this embodiment, the oxygen scavenging assembly 300 can be disposed above the oxygen scavenging region 211. The oxygen consumption part 320 faces the inside of the storage container 200, and oxygen in the storage container 200 may contact the oxygen consumption part 320 through the oxygen removing region 211. And an electrolytic part 310 facing away from the inside of the storage container 200 and exposed to the outside of the storage container 200. A proton exchange membrane for transporting hydrogen ions may be disposed between the oxygen consumption part 320 and the electrolysis part 310.
That is, the oxygen removing assembly 300 performs an electrochemical reaction using water vapor outside the container 200 and oxygen inside the container 200 as reactants to reduce the oxygen content inside the container 200. The electrochemical reaction comprises two half reactions respectively occurring in the electrolysis part 310 and the oxygen consumption part 320, the electrolysis part 310 electrolyzes water vapor outside the storage container 200 under the action of electrolysis voltage to generate hydrogen ions and oxygen, the proton exchange membrane is configured to transport the hydrogen ions from one side of the electrolysis part 310 to one side of the oxygen consumption part 320, and the oxygen consumption part 320 promotes the hydrogen ions generated by the electrolysis part 310 to electrochemically react with the oxygen inside the storage container 200 to generate water to consume the oxygen inside the storage container 200 under the action of the electrolysis voltage, so that a low-oxygen fresh-keeping environment is formed inside the storage container 200.
In this embodiment, the oxygen removing assembly 300 may further include two elastic plates respectively disposed on a side of the electrolysis portion 310 facing away from the proton exchange membrane and a side of the oxygen consuming portion 320 facing away from the proton exchange membrane, for connecting with other structures to achieve fixation. The middle part of the elastic plate is hollowed out so that the electrolysis part 310 and the oxygen consumption part 320 are in contact with the surrounding air.
The moisture permeable assembly 400 is disposed on the storage container 200 and located on at least one side of the oxygen removing assembly 300, preferably, the moisture permeable assembly 400 may be disposed on the top surface of the storage container 200, and two moisture permeable assemblies 400 are respectively located on two sides of the oxygen removing assembly 300. A moisture permeable assembly 400 configured to allow water vapor within the storage container 200 to permeate. The moisture permeable assembly 400 may be overlaid over the water removal region 212 of the air permeable region, i.e., the moisture permeable assembly 400 is overlaid on the air permeable region alongside the oxygen scavenging assembly 300, collectively enclosing the air permeable region. Because water is also generated when oxygen in the storage container 200 is consumed during operation of the oxygen removal assembly 300, moisture accumulation can lead to an increase in humidity, and suitably increasing humidity is beneficial to improving the preservation effect. The moisture permeable assembly 400 is configured to allow water vapor in the storage container 200 to slowly permeate and be discharged to the outside of the storage container 200, so that the humidity in the storage container 200 can be always kept in a proper range, and condensation or dripping caused by excessive water in the space can be prevented.
In particular, in order to promote the rapid discharge of the water vapor in the storage container 200, the refrigerator 10 of the present embodiment is further provided with a first blower 500. The first fan 500 is disposed inside the storage container 200 and configured to promote airflow through the moisture permeable assembly 400. The first fan 500 may be disposed on a side of the oxygen scavenging assembly 300 facing the interior of the storage container 200.
In the embodiment, the first fan 500 is disposed inside the storage container 200 and configured to promote the formation of the airflow flowing through the moisture permeable assembly 400, and the first fan 500 is utilized to accelerate the rate of the air in the storage container 200 flowing through the surface of the moisture permeable assembly 400, so as to increase the probability of the contact between the water vapor in the storage container 200 and the moisture permeable assembly 400, increase the moisture permeable efficiency of the moisture permeable assembly 400, and reduce or avoid the condensation or water dripping phenomenon inside the storage container 200.
The first fan 500 may be a centrifugal fan, an air inlet of the first fan 500 faces back to the oxygen consumption portion 320, an air outlet of the first fan 500 faces the side wall of the storage container 200, and an air flow below the air inlet is sucked by the first fan 500, discharged from the air outlet, and flows through the bottom of the moisture permeable assembly 400.
Because the oxygen scavenging assembly 300 operates to scavenge oxygen from the container 200 while also generating water, operation of the oxygen scavenging assembly 300 increases the humidity within the container 200. When the humidity in the storage container 200 is too high, if the oxygen removing assembly 300 is continuously operated, the condensation may drip, which may deteriorate the storage environment. In this embodiment, when the humidity within the storage container 200 is greater than the predetermined humidity threshold, the operation of the oxygen scavenging assembly 300 is suspended to preferentially adjust the humidity within the storage container 200. Correspondingly, the first fan 500 is turned on and promotes the rapid seepage of the water vapor in the storage container 200, when the humidity adjusting time is longer than or equal to the first preset working duration, the first fan 500 is stopped, and when the pause operation duration of the oxygen removing assembly 300 is longer than or equal to the preset pause duration, the oxygen removing assembly 300 resumes operation and continues to remove oxygen for the storage container 200, so that the oxygen removing assembly 300 always operates in a suitable humidity range, and internal condensation or water dripping is reduced or avoided while a good oxygen removing effect is obtained.
In some optional embodiments, the air inlet of the first blower 500 may also face the oxygen consumption portion 320, and the first blower 500 may also be synchronously turned on when the oxygen removing assembly 300 is turned on, so that water vapor near the oxygen consumption portion 320 may be blown to other portions inside the storage container 200 by the stirring effect of the first blower 500 on the air inside the storage container 200, thereby reducing or avoiding the condensation problem of the oxygen consumption portion 320 caused by the accumulation of water vapor near the oxygen consumption portion 320, and thus providing an advantage for the oxygen consumption portion 320 to rapidly perform an electrochemical reaction, and improving the oxygen removing efficiency of the oxygen removing assembly 300.
And a second fan 600 disposed on a side of the oxygen removing assembly 300 facing the outside of the storage container 200, and configured to promote the formation of an air flow through the electrolytic part 310. The second blower 600 may be a micro axial flow blower having a rotation axis perpendicular to the electrolytic part 310 for blowing air outside the storage container 200 toward the electrolytic part 310.
In some optional embodiments, the refrigerator 10 may further include a first fan support fixedly supporting the first fan 500 and a second fan support fixedly supporting the second fan 600, wherein the blowing area of the second fan 600 faces the circular opening in the middle of the second fan support and is capable of blowing the air flow to the electrolysis part 310. The second fan support can fixedly support the second fan 600, so that the second fan 600 is prevented from shaking in operation, and meanwhile, a certain distance can be formed between the second fan 600 and the electrolysis part 310, and gas circulation is facilitated. The second fan bracket may be connected to the elastic plate at the side of the electrolytic part 310 of the oxygen removing assembly 300 by a screw connection to fix the second fan 600. Similarly, the first fan bracket can fixedly support the first fan 500, and can also be connected with the elastic plate on the side of the oxygen consumption part 320 of the oxygen removing assembly 300 by a screw connection manner to fix the first fan 500.
The second fan 600 is opened and closed accordingly as the oxygen removal assembly 300 is opened and closed. That is, after the oxygen removal assembly 300 is turned on, the second fan 600 is turned on, and after the oxygen removal assembly 300 is turned off, the second fan 600 is turned off.

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 oxygen scavenging assembly 300 is configured to start up when the oxygen concentration within the storage container 200 is greater than a preset concentration threshold.
That is, when the oxygen concentration in the storage container 200 exceeds the preset concentration threshold, the oxygen concentration is high, and the oxygen removing assembly 300 needs to be used for reducing the oxygen concentration in the storage container 200; after the oxygen removal assembly 300 is turned on, the second fan 600 is turned on.
And a humidity sensor 260 disposed in the storage container 200 and configured to detect humidity in the storage container 200 every first preset time during the operation of the oxygen removing assembly 300. The humidity sensor 260 may be disposed on a sidewall of the storage container 200.
The oxygen consuming portion 320 of the oxygen scavenging assembly 300 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, consequently, need utilize humidity transducer 260 to detect the inside humidity of storage container 200 in deoxidization subassembly 300 operation process to adjust the deoxidization process and pass through wet process correspondingly according to the humidity value, make storage container 200 reduce or avoid inside condensation or the phenomenon of dripping to take place when obtaining better deoxidization effect.
The first blower 500 is configured to be turned on when the humidity in the storage container 200 is greater than a predetermined humidity threshold, and the oxygen removal assembly 300 is configured to be suspended when the humidity in the storage container 200 is greater than the predetermined humidity threshold during operation thereof.
When the humidity in the storage container 200 is greater than the preset humidity threshold, it means that the concentration of the water vapor in the storage container 200 is too high, and the humidity should be preferentially adjusted, accordingly, the first fan 500 is turned on to increase the air flow speed in the storage container 200, so as to promote more water vapor to contact the surface of the moisture permeable component 400, and accelerate the water vapor to be discharged to the outside of the storage container 200 through the moisture permeable component 400. When the humidity in the storage container 200 is greater than the preset humidity threshold, if the oxygen removal assembly 300 is continuously operated, the electrochemical reaction of the oxygen removal assembly continues to generate water, which is not beneficial to quickly reduce the water vapor concentration in the storage container 200, therefore, the operation of the oxygen removal assembly 300 should be suspended, and after the humidity is controlled within a reasonable range, the oxygen removal assembly 300 is continuously operated to remove oxygen in the storage container 200.
The first fan 500 is also configured to shut down when its operational duration is greater than or equal to a first preset operational duration.
After first fan 500 opens, will be according to the continuous operation of first preset operating duration, this first preset operating duration can set up according to actual need to after first fan 500 continuously operated first preset operating duration, humidity in the storing container 200 can reduce to below the reasonable humidity threshold value of presetting, and the reasonable humidity threshold value of presetting is less than first preset humidity threshold value.
The oxygen scavenging assembly 300 is further configured to resume operation when its pause period is greater than or equal to a preset pause period, and the preset pause period is greater than the first preset operating period.
In the operation process of the first fan 500, the oxygen removing assembly 300 is always kept in the pause operation state, the duration of the pause operation state is the preset pause time, after the first fan 500 is stopped, and the pause time of the oxygen removing assembly 300 is greater than or equal to the preset pause time, the oxygen removing assembly 300 can be resumed to operate again to continue removing oxygen in the storage container 200.
The oxygen scavenging assembly 300 is shut down when its operating period is greater than or equal to a second preset operating period.
During operation of the oxygen scavenging assembly 300, the oxygen content continues to decrease due to the relatively closed reservoir 200, resulting in a reduced concentration of the reactant for the electrochemical reaction of the oxygen scavenging assembly 300, which in turn may be less efficient or even not at all. When the operating time of the oxygen scavenging assembly 300 is greater than or equal to the second predetermined operating time, meaning that the electrolytic efficiency of the oxygen scavenging assembly 300 is already low, the electrochemical reaction of the oxygen scavenging assembly 300 needs to be terminated to avoid wasting too much electrical energy and compromising the life of the oxygen scavenging assembly 300.
The second of deoxidization subassembly 300 is predetermine operating time and can be set up according to actual demand to in this second is predetermine operating time, the oxygen concentration in the storing container 200 can reduce to predetermineeing below the reasonable concentration threshold value, should predetermine reasonable concentration threshold value and be less than and predetermine the concentration threshold value.
Fig. 7 is a control flowchart of the refrigerator 10 according to one embodiment of the present invention.
In step S702, a signal indicating that the storage container 200 is closed is obtained. Storing container 200 can lead to its inside original storing atmosphere to be destroyed with the outside air intercommunication under the state of opening, consequently, storing container 200 is closed the back, whether needs to redetermine inside oxygen concentration and satisfy the storing requirement, if unsatisfied, then need start deoxidization subassembly 300 and carry out the deoxidization, build the fresh-keeping atmosphere of hypoxemia again.
In step S704, the oxygen concentration detected by the oxygen concentration sensor 250 is acquired.
Step S706, judging whether the oxygen concentration is greater than a preset concentration threshold value, if so, executing step S708, which means that the oxygen concentration is higher at this time, and the oxygen removing assembly 300 needs to be started to remove oxygen from the storage container 200; if not, the process returns to step S704.
In step S708, the oxygen removal assembly 300 is turned on, and the second fan 600 is turned on. The second fan 600 facilitates the airflow outside the storage container 200 to flow to the electrolysis part 310 of the oxygen removing assembly 300, so as to supplement the water vapor required for the electrochemical reaction to the electrolysis part 310, accelerate the electrochemical reaction rate, and improve the oxygen removing efficiency of the oxygen removing assembly 300.
In step S710, the humidity detected by the humidity sensor 260 is acquired. The humidity in the storage container 200 is detected every first preset time during the operation of the oxygen removal assembly 300, and the humidity in the storage container 200 is monitored during the operation of the oxygen removal assembly 300, so that the humidity can be adjusted in time.
Step S712, determining whether the humidity is greater than a preset humidity threshold, if so, performing step S714, which means that the humidity in the storage container 200 is higher, the humidity needs to be preferentially adjusted, and oxygen removal is suspended; if not, the process returns to step S710 to continue monitoring the humidity in the storage container 200.
In step S714, the first fan 500 is turned on, the oxygen removing assembly 300 is suspended, and the second fan 600 is suspended. After the first fan 500 is started, airflow flowing through the moisture permeable assembly 400 is formed in the storage container 200, so that the water vapor permeation efficiency in the storage container 200 is improved, and in the process that the first fan 500 promotes the water vapor in the storage container 200 to be discharged, the deoxidization assembly 300 and the second fan 600 are suspended for operation, so that the dehumidification efficiency is prevented from being influenced by water generated in the operation process of the deoxidization assembly 300.
In step S716, the first fan 500 is shut down after reaching a shutdown condition, where the operation duration of the first fan 500 is greater than or equal to a first preset operation duration.
In step S718, the oxygen removal assembly 300 continues to operate, and the second fan 600 continues to operate. After the first blower 500 is stopped, meaning that the humidity in the storage container 200 has been reduced to below the preset reasonable humidity threshold at this time, the oxygen removal assembly 300 can resume to operate to continue to remove oxygen from the storage container 200, and the second blower 600 is correspondingly opened along with the opening of the oxygen removal assembly 300.
Step S720, determining whether the shutdown condition of the oxygen removal assembly 300 is met, if yes, executing step S722; if not, the process returns to step S710, and the humidity inside the storage container 200 is continuously monitored during the operation of the oxygen removing assembly 300.
In step S722, the oxygen removal assembly 300 is stopped and the second fan 600 is stopped. Under the storing container 200 keeps closed state, when the operating duration of deoxidization subassembly 300 is more than or equal to and predetermines the operating duration, can reduce the oxygen concentration in the storing container 200 to predetermineeing below the reasonable concentration threshold value, for avoiding consuming too much electric energy, deoxidization subassembly 300 and second fan 600 shut down.
In particular, if the storage container 200 is opened, the oxygen removing assembly 300 and the first fan 500 are stopped or maintained in a stopped state.
In the refrigerator 10 of the embodiment, when the humidity in the storage container 200 is greater than the preset humidity threshold, the operation of the oxygen removal assembly 300 is suspended, and the humidity in the storage container 200 is preferentially adjusted, accordingly, the first fan 500 is turned on to promote rapid seepage of water vapor in the storage container 200, when the humidity adjustment time is greater than or equal to the first preset working time, the first fan 500 is stopped, and when the operation suspension time of the oxygen removal assembly 300 is greater than or equal to the preset suspension time, the oxygen removal assembly 300 resumes to operate to continue to remove oxygen for the storage container 200, so that the oxygen removal assembly 300 always operates in a suitable humidity range, and internal condensation or water dripping is reduced or avoided while a good oxygen removal effect is obtained.
