In some alternative embodiments, the partition 210 may also be disposed laterally inside the storage device 200, such that the second storage area 230 is located above the first storage area 220. In this embodiment, the first storage area 220 may have an openable and closable door body, and the second storage area 230 may be a drawer that can be drawn; the first and second storage regions 220 and 230 cannot exchange gas due to the partition blocking function of the partition 210; first storage district 220 can be for doing the district, and the dry storage environment that keeps inside dry is made to the humidity that needs control in the district, and second storage district 230 can be the fresh-keeping district of hypoxemia, and the fresh-keeping storage environment that keeps the inside high humidity of hypoxemia that makes is kept to the oxygen content of needs control and humidity in the district of hypoxemia.
In this embodiment, the refrigerator 10 may be an air-cooled refrigerator 10, and the air-cooled refrigerator 10 cools the storage compartment by using air flow circulation.
The first storage area 220 is formed with an air inlet 221 and an air outlet 222, and the air flow after heat exchange with the evaporator of the refrigerator 10 flows through the air inlet 221, the inside of the first storage area 220, and the air outlet 222 to exchange air with the first storage area 220.

The oxygen generated by the first electrolysis part can be discharged from the air outlet. The first oxygen removal assembly 250 may be disposed at the mounting opening of the partition 210 and on the side of the partition 210 facing the first storage area 220, that is, the first oxygen removal assembly 250 is disposed in the first storage area 220 and is disposed adjacent to the partition 210, and the first oxygen removal assembly 250 forms a side facing the first storage area 220 and a side facing away from the first storage area 220, and the side facing away from the first storage area 220 communicates with the second storage area 230 through the mounting opening and faces the second storage area 230.

For example, when the humidity in the first storage area 220 is low, the humidity in the first storage area 220 can be maintained within a desired humidity range by controlling the airflow of the refrigerator 10 to flow through the first storage area 220; when the humidity in the first storage area 220 is high, the first oxygen-removing component 250 needs to be turned on to consume the water vapor in the area by using an electrochemical reaction, so as to achieve the purpose of rapidly reducing the internal humidity.
In this embodiment, the electrochemical reaction of the first oxygen removing assembly 250 is utilized to electrolyze the water vapor in the first storage area 220, so as to reduce the internal humidity and form a dry storage environment. Compared with the prior art that the cold air dried in the freezing chamber is conveyed to the dry area in the refrigerator 10 and the water vapor in the dry area is taken away, the method reduces or avoids the temperature of the dry area from generating large fluctuation, and improves the temperature uniformity of the storage chamber.

The first fan is connected with the first fan support to fix the fan, the air supply area of the first fan is opposite to the round opening in the middle of the first fan support, and air flow can be blown to the inside of the proton exchange membrane group and blown to the anode plate. First fan support can the first fan of fixed support, prevents that first fan from rocking when the operation, can also make simultaneously and form certain interval between first fan and the elastic plate to do benefit to the circulation of gas.
The first fan mount may be attached to the first fan assembly 260 by a flexible plate that is attached to the outside of the anode plate of the first oxygen removal assembly 250, for example, by bolting.
The top surface of the second storage area 230 is provided with a ventilation area, which may be an opening or a through hole arranged in an array, and the gas in the second storage area 230 can escape from the ventilation area. The ventilative regional water removing area and the deoxidization district of including, deoxidization position in ventilative regional middle part, the water removing area is located the both sides in oxygen removing area.
And a second oxygen removal assembly 270 disposed on the top of the second storage region 230, wherein a side of the second oxygen removal assembly 270 facing the second storage region 230 is configured as a second oxygen consumption portion, a side facing away from the second storage region 230 is configured as a second electrolysis portion, the second electrolysis portion electrolyzes water vapor near the second electrolysis portion under the action of an electrolysis voltage to generate hydrogen ions and oxygen, and the second oxygen consumption portion promotes the hydrogen ions generated by the second electrolysis portion to react with the oxygen in the second storage region 230 to generate water under the action of the electrolysis voltage. That is, the second oxygen scavenging assembly 270 alone scavenges oxygen from the second reservoir region 230. In this embodiment, the second oxygen removing member 270 may be disposed outside and adjacent to the top surface of the second storage region 230 and located in the middle of the air permeable region, i.e. the second oxygen removing member 270 covers the oxygen removing region, and oxygen in the second storage region 230 can contact the second oxygen consuming part of the second oxygen removing member 270 through the oxygen removing region. The side of the second oxygen removal assembly 270 that uses oxygen as a reactant, i.e., the second oxygen consumption portion, faces the second storage region 230, and can consume oxygen in the second storage region 230 through an electrochemical reaction, and the side of the second oxygen removal assembly 270 that uses water vapor as a reactant, i.e., the second electrolysis portion, is exposed outside the storage device 200, and can electrolyze water vapor outside the storage device 200 through an electrochemical reaction.
In some alternative embodiments, the second oxygen scavenging assembly 270 and the first oxygen scavenging assembly 250 can also be turned on simultaneously to cause the oxygen concentration in the second reservoir region 230 to decrease rapidly, thereby achieving a rapid oxygen scavenging effect.
The second oxygen removing assembly 270 may include a second mounting frame and a second proton exchange membrane module, and the structures of the second mounting frame and the second proton exchange membrane module and the arrangement method on the top of the second storage area 230 may be similar to those of the first oxygen removing assembly 250, and are not described herein again.
A second fan assembly 280 disposed on a side of the second oxygen scavenging assembly 270 facing away from the interior of the second storage region 230 is configured to promote air outside the storage device 200 to blow toward the second oxygen scavenging assembly 270. The second fan assembly 280 may include a second fan and a second fan support, and the structure and the fixing method of the second fan and the second fan support are similar to those of the first fan assembly 260, which is not described herein again.
Moisture permeable components 290 disposed on top of the second storage region 230 and on either side of the second oxygen scavenging component 270 are configured to allow water vapor within the second storage region 230 to permeate. A moisture permeable member 290 also disposed outside and abutting the top surface of the second storage region 230 and covering the air permeable region; specifically, moisture permeable components 290 are positioned on either side of the second oxygen scavenging component 270, i.e., the moisture permeable components 290 overlie the water removal zone and overlie the air permeable region alongside the second oxygen scavenging component 270, collectively enclosing the air permeable region. The moisture permeable assembly 290 includes a moisture permeable film and a moisture permeable substrate.
Since water is also generated by the first and second oxygen scavenging assemblies 250 and 270 when the second storage area 230 is deoxygenated, moisture accumulation can lead to increased humidity, which is desirable to improve freshness benefits. The moisture permeable film is configured to allow water vapor in the second storage region 230 to slowly permeate therethrough and be discharged to the outside of the storage device 200, so that the humidity in the second storage region 230 is always maintained within a suitable range, preventing condensation or dripping due to excessive moisture in the space. In this embodiment, the moisture permeable membrane may be a pervaporation membrane, and has a hydrophilic layer and a hydrophobic layer, one side of the hydrophilic layer facing away from the hydrophobic layer faces the inside of the second storage area 230, one side of the hydrophobic layer facing away from the hydrophilic layer faces the inside of the second storage area 230, and water vapor in the inside of the second storage area 230 can be discharged to the outside of the storage device 200 through permeation of the moisture permeable membrane. The moisture permeable film can block the permeation of other gases while permeating water vapor, thereby preventing the exchange of gases between the inside and outside of the second storage region 230.
The moisture permeable bottom plate is attached to the bottom of the moisture permeable film to support the moisture permeable film. The moisture-permeable bottom plate is provided with through holes which are arranged in an array mode so as to allow the gas escaping from the gas-permeable area to pass through.
Since the first storage area 220 and the second storage area 230 are likely to be opened at any time during the use of the refrigerator 10 for the article taking and placing actions, the closing action may cause the exchange of the materials inside and outside the storage areas, and therefore, the first oxygen removing assembly 250 and the second oxygen removing assembly 270 allow the start-up and operation when the refrigerator door is in the closed state.
The humidity sensor 240 is disposed in the first storage region 220 and configured to detect humidity in the first storage region 220 at predetermined time intervals.
The refrigerator 10 is configured to activate the first oxygen removal assembly 250 and activate the first fan assembly 260 when the humidity of the first storage region 220 is greater than or equal to a first preset threshold. The refrigerator 10 is configured such that the second oxygen removal assembly 270 and the second fan assembly 280 are periodically activated to periodically remove oxygen from the second storage region 230 while the first oxygen removal assembly 250 is in an off state.
That is, when the humidity in the first storage area 220 reaches or exceeds the first predetermined threshold, the humidity in the area cannot be rapidly reduced by the airflow supplied from the refrigerator 10 alone, the electrochemical reaction of the first oxygen removal assembly 250 needs to be activated for dehumidification, and the first fan assembly 260 may be activated simultaneously with the first oxygen removal assembly 250 or may be activated at predetermined intervals before or after the first oxygen removal assembly 250 is activated.
When the humidity in the first storage area 220 is less than the first preset threshold, the dehumidification requirement of the first storage area 220 can be met by independently relying on the air flow of the refrigerator 10 without starting the electrochemical reaction of the first oxygen removal assembly 250 for dehumidification; accordingly, the first fan assembly 260 also need not be activated. At this point, the second reservoir area 230 cannot be deoxygenated by the electrochemical reaction of the first oxygen removal assembly 250, and in the shutdown state of the first oxygen removal assembly 250, the second reservoir area 230 needs to control the second oxygen removal assembly 270 and the second fan assembly 280 to periodically activate for periodic oxygen removal according to the actual oxygen removal requirement inside. Since the second storage area 230 cannot be kept in an absolute closed state, as the closed time is prolonged, external air slowly permeates into the second storage area, and the oxygen content in the second storage area increases, oxygen removal is required according to a certain period, so that a good fresh-keeping effect is achieved, and excessive power consumption can be avoided. The periodic oxygen removal can be set at regular intervals and at run times as desired, with the second oxygen removal assembly 270 and the second fan being in an off state for the intervals and then in an on state for the run times.
After the first oxygen scavenging assembly 250 is activated, it is shut down after a shut down condition is reached, which includes: when the humidity in the first storage area 220 decreases below a second predetermined threshold, the first predetermined threshold is greater than the second predetermined threshold; and/or the first oxygen removal assembly 250 has an operating time period greater than or equal to a preset operating time period. After the first deoxidization subassembly stops, first fan shuts down.
Either of the two shut down conditions described above may be achieved to cause the first oxygen removal assembly 250 to shut down.
During operation of the first oxygen removal assembly 250, the humidity sensor 240 senses the humidity within the first storage area 220 at predetermined intervals. When the humidity of the first storage area 220 is reduced below the second predetermined threshold, meaning that the dry storage environment can be maintained under the action of the supply airflow without performing the electrolytic dehumidification by using the electrochemical reaction of the first oxygen removal assembly 250, at this time, even if the operation duration of the first oxygen removal assembly 250 does not reach the predetermined operation duration, the electrochemical reaction of the first oxygen removal assembly 250 is terminated to avoid excessive power consumption.
During operation of the first oxygen scavenging assembly 250, since the first storage area 220 is relatively closed and the supply air stream is relatively dry, water cannot be replenished into the area and the water vapor content in the area continues to decrease. After the water vapor content in the first storage area 220 is continuously reduced, the reactant content of the first oxygen removal assembly 250 is reduced, and accordingly the electrochemical reaction efficiency is reduced, and if the electrochemical reaction is continued, the water vapor content in the first storage area 220 cannot be obviously reduced, and the benefit is little while consuming electric energy. The life of the first oxygen scavenging assembly 250 is related to the run time, with longer run times and shorter lives. When the operating time of the first oxygen scavenging assembly 250 is greater than or equal to the predetermined operating time, meaning that the electrolytic efficiency of the first oxygen scavenging assembly 250 is already low, the electrochemical reaction of the first oxygen scavenging assembly 250 is terminated even if the humidity within the first reservoir region 220 does not drop below the second predetermined threshold, so as to avoid wasting too much electrical energy while compromising the life of the first oxygen scavenging assembly 250. After the first oxygen scavenging assembly 250 is deactivated, the airflow from the refrigerator 10 will still blow on the first storage area 220, and the humidity in the first storage area 220 will continue to decrease.
Fig. 3 is a control flowchart of the refrigerator 10 according to one embodiment of the present invention. The control flow is carried out when the refrigerator door body is in a closed state.
In step S302, the humidity detected by the humidity sensor 240 is acquired.
Step S304, determining whether the humidity is greater than or equal to a first preset threshold, if so, performing step S306, which means that the start-up condition of the first oxygen removing assembly 250 is reached; if not, go to step S316 directly.
In step S306, the first oxygen removal assembly 250 is activated and the first fan assembly 260 is activated.
In step S308, the humidity detected by the humidity sensor 240 is acquired at preset time intervals.
Step S310, determining whether the humidity of the first storage area 220 is reduced below a second preset threshold, if so, performing step S314, where a shutdown condition of the first oxygen removal assembly 250 is reached; if not, step S312 is executed to determine whether the shutdown condition of the first oxygen removal assembly 250 is met.
Step S312, determining whether the operation time of the first oxygen removing assembly 250 is greater than or equal to the preset operation time, if so, executing step S314, stopping the first oxygen removing assembly 250, turning off the first fan, otherwise, executing step S308, and obtaining the humidity detected by the humidity sensor 240 again after a preset time interval.
In step S314, the first oxygen removal assembly 250 is stopped and the first blower 260 is turned off.
In step S316, the second oxygen removal assembly 270 and the second fan assembly 280 are periodically activated to periodically remove oxygen from the second storage area 230 while the first oxygen removal assembly 250 is in the off state.
In the refrigerator 10 of the present embodiment, the vertically disposed partition 210 is used to divide the storage device 200 into the first storage region 220 and the second storage region 230 disposed side by side, the first oxygen removing member 250 is disposed on the partition 210, a surface facing the first storage region 220 is configured to electrolyze water vapor in the second storage region 230 by an electrochemical reaction under an electrolytic voltage, and a surface facing the second storage region 230 is configured to consume oxygen in the second storage region 230 by an electrochemical reaction under an electrolytic voltage. When first deoxidization subassembly 250 starts the operation, it is when consuming the vapor in first storage district 220, has also consumed the oxygen in second storage district 230 for first storage district 220 forms dry storing environment and second storage district 230 forms the fresh-keeping environment of low oxygen, thereby only need to regulate and control the storing environment in can two storage districts of simultaneous control to same deoxidization subassembly, simple structure, easily operation, economic saving.
In the refrigerator 10 of the present embodiment, the electrochemical reaction of the first oxygen removing assembly 250 is utilized to electrolyze the water vapor in the first storage area 220, so as to reduce the internal humidity and form a dry storage environment. Compared with the prior art that the cold air dried in the freezing chamber is conveyed to the dry area in the refrigerator 10 and the water vapor in the dry area is taken away, the method reduces or avoids the temperature of the dry area from generating large fluctuation, and improves the temperature uniformity of the storage chamber. In the refrigerator 10 of the present embodiment, a moisture permeable member 290 is further disposed on the top surface of the second storage region 230, and is configured to allow water vapor in the second storage region 230 to seep out, so as to prevent condensation or water dripping due to excessive water vapor, which is beneficial to maintaining a good fresh-keeping effect of the second storage region 230.
