In summary, the skilled in the art can set the electrolytic oxygen removing device 40 according to the actual situation after knowing the technical solution of the present embodiment, which is not listed here.
Referring to fig. 3 to 5, fig. 3 is an exploded view of an electrolytic oxygen removal device 40 in a refrigerator 1 according to an embodiment of the present invention, fig. 4 is a cross-sectional view of the electrolytic oxygen removal device 40 in the refrigerator 1 according to an embodiment of the present invention, and fig. 5 is a schematic view of a rear case 120 in the electrolytic oxygen removal device 40 in the refrigerator 1 according to an embodiment of the present invention. In some embodiments, the electrolytic deoxygenating device 40 may further include a housing 100 and a moisture separator 400, the housing 100 has a receiving cavity 140 therein, the housing 100 has a plurality of steam vents 126, the moisture separator 400 is disposed in the receiving cavity 140, the moisture separator 400 has a water absorption plate 410 disposed at the bottom of the receiving cavity 140 and an evaporation plate 420 extending upward from one end of the water absorption plate 410, and the moisture separator 400 is configured to absorb water collected at the bottom of the receiving cavity 140 by the water absorption plate 410, transfer the water to the evaporation plate 420 for evaporation, and finally discharge the water from the steam vents 126.
Since the electrolytic oxygen removing device 40 generally requires liquid electrolyte for electric conduction in the electrochemical reaction, and a large amount of heat is generated in the electrochemical reaction, and the local temperature will rise accordingly, so that the moisture in the electrolyte may be heated by the heat to evaporate, the electrolytic oxygen removing device 40 of the present embodiment can collect the water evaporated from the electrolyte by using the accommodating cavity 140.
The water absorption plate 410 and the evaporation plate 420 of the dehumidifying element 400 can be of an integral structure and made of materials with water absorption capacity (such as non-woven fabric laminated boards, fiberboards and the like), the water absorption element is arranged at the bottom of the accommodating cavity 140, so that the water absorption plate 410 can absorb and collect water at the bottom of the accommodating cavity 140, the water absorbed in the water absorption plate is transferred to the evaporation plate 420 by utilizing capillary phenomenon, water vapor is evaporated on the evaporation plate 420, and finally formed water vapor can be discharged out of the accommodating cavity 140 through the plurality of steam discharging holes 126, and the dehumidifying work is completed.
Referring to fig. 3 to 5, in some embodiments, the housing 100 may further include a front shell 110 and a rear shell 120, and the front shell 110 and the rear shell 120 are fastened to form a receiving cavity 140 and may be connected together by a fastener.
Because the evaporation plate 420 is at least partially opposite to the plurality of steam exhaust holes 126, and the plurality of steam exhaust holes 126 are opened in the rear shell 120, the evaporation plate 420 can also be arranged close to the rear shell 120, the rear shell 120 can also be arranged on the side of the electrolytic oxygen removing device 40 far away from the storage compartment, so that the evaporation plate 420 is far away from the storage compartment, and the steam exhausted from the plurality of steam exhaust holes 126 is also far away from the storage compartment, thereby preventing secondary moisture regain.
Referring to fig. 5, further, the inner surface of the rear shell 120 is formed with a raised rib 122 disposed in a closed surrounding manner, a plurality of steam discharge holes 126 are distributed in the raised rib 122, and the evaporation plate 420 abuts against the raised rib 122.
When the evaporation plate 420 abuts against the raised ribs 122 inside the rear shell 120, the raised ribs 122 can divide the evaporation plate 420 into an open area and a closed area, the open area of the evaporation plate 420 is opposite to the portion of the rear shell 120 inside the raised ribs 122, and the rest is the closed area of the evaporation plate 420.
Because the plurality of steam discharge holes 126 are uniformly distributed in the inner area of the raised ribs 122, water on the open area can be discharged out of the accommodating cavity 140 from the plurality of steam discharge holes 126 after being evaporated, when a part of water in the open area is evaporated, water in the sealed area can be continuously supplemented to the open area, and finally, water in the whole evaporation plate 420 is discharged.
Since the open area of the evaporation plate 420 is communicated with the external environment through the steam exhaust holes 126, and the closed area is not communicated with the external environment due to the blocking of the raised ribs 122, air in the external environment cannot enter the inside of the accommodating cavity 140 through the plurality of steam exhaust holes 126, and the influence of the external environment on the oxygen removing efficiency of the electrolytic oxygen removing device 40 is avoided.
Referring to fig. 3 and 4, in some embodiments, the front housing 110 has an opening 112, and the electrolytic deoxygenator device 40 may further include a cooling condensation plate 210 and an electrolytic bin 300, the cooling condensation plate 210 is disposed in the accommodating cavity 140 and located at the opening 112, the cooling condensation plate 210 is opened with a plurality of air inlets 212 to allow external air to enter the accommodating cavity 140, and the electrolytic bin 300 is disposed in the accommodating cavity 140 and configured to separate oxygen from air entering the accommodating cavity 140 from the plurality of air inlets 212 through an electrochemical reaction.
In some specific embodiments, the communicating hole of the inner container or the drawer body of the refrigerator 1 is provided with a plurality of communicating holes (not shown in the figures), the electrolytic oxygen removing device 40 can be arranged outside the inner container or the drawer body, and the air inlet 212 on the cooling condensation plate 210 is opposite to the communicating holes, so that the air in the storage compartment can sequentially pass through the communicating holes and the air inlet 212 to enter the accommodating cavity 140, and then enter the inside of the electrolytic bin 300 to perform electrochemical reaction.
In other embodiments, the inner container or the drawer body may further have a fastening hole (not shown), and the housing 100 of the electrolytic oxygen removing device 40 can be fastened in the fastening hole, so that the cooling condensation plate 210 is directly exposed in the storage compartment, and the air in the storage compartment can directly enter the accommodating cavity 140 through the air inlet 212.
In some embodiments, one side of the electrolytic bin 300 may be opened to form an oxygen inlet, and the oxygen inlet may be provided with a cathode plate having waterproof and breathable functions, so that air can enter the inside of the electrolytic bin 300 through the cathode plate and prevent the electrolyte in the electrolytic bin 300 from flowing out, that is, in this embodiment, the cathode plate may be used as at least one part of one wall surface of the electrolytic bin 300, and in order to improve air intake efficiency, the cathode plate may be arranged facing the storage compartment.
The negative pole of external power source can be loaded to the negative pole, takes place reduction reaction after the air in the storing space gets into electrolysis storehouse 300, generates the anion, promptly: o is 2 +2H 2 O+4e - →4OH - 。
Electrolyte can be contained in the electrolytic bin 300, the anode plate can be arranged in the electrolytic bin 300 and is loaded with the anode of an external power supply, negative ions generated at the cathode plate flow to the anode plate under the action of an electric field and are subjected to oxidation reaction on the anode plate to generate oxygen, namely: 4OH - →O 2 +2H 2 O+4e - Therefore, oxygen in the air can be separated out and then discharged, and the oxygen content of the air in the storage chamber is reduced.
Therefore, the side of the electrolytic bin 300 facing the storage compartment can be a waterproof and breathable cathode plate, and when the electrolytic bin 300 is integrally arranged in the accommodating cavity 140 of the cover case 100, the waterproof and breathable cathode plate can be further protected, so that the cathode plate is prevented from being punctured by an external object to cause electrolyte leakage and accidents.
Referring to fig. 3 and 6, fig. 6 is a schematic view of the cooling condensation plate 210, the connection plate 220, and the cold source plate 230 of the electrolytic oxygen removal device 40 according to an embodiment of the present invention. Further, the electrolytic oxygen removing device 40 may further include a connection plate 220 and a cold source plate 230, the connection plate 220 is formed at the top end of the cooling condensation plate 210 and extends to the outside of the rear case 120, and the cold source plate 230 is formed at the end of the connection plate 220 and is attached to the outer wall of the rear case 120 to conduct the cold thereon to the cooling condensation plate 210 through the connection plate 220, so as to condense the water vapor flowing thereon by using the cooling condensation plate 210.
Specifically, the cooling condensation plate 210, the connection plate 220, and the cold source plate 230 may also be an integrated plate and made of a metal material with good thermal conductivity (e.g., aluminum, copper, etc.), the rear housing 120 has an insertion gap 124 (as shown in fig. 5) for the connection plate 220 to extend out, and the connection plate 220 extends out of the insertion gap 124 after extending out from the top end of the cooling condensation plate 210 and finally fits outside the rear housing 120. The electrolytic oxygen removal device 40 may be provided at the rear wall of the inner container or the drawer body, and for the refrigerator 1, a cooling chamber for supplying the cooling capacity is generally provided at the rear of the refrigerator 1, so that the cold source plate 230 may be closer to the steam cooling chamber to absorb the cooling capacity of the cooling chamber.
The inventors have realized that: often produce a large amount of heats when carrying out electrochemical reaction in the electrolysis storehouse 300, local temperature also can rise correspondingly, moisture in the electrolyte can be heated and evaporate by these heats like this, because storing room and holding chamber 140 pass through the intercommunicating pore intercommunication, consequently, the moisture of evaporating out still can get into in the storing room, make the indoor humidity of storing room rise, influence the humidity control of storing room, and meet the cold extremely easy condensation phenomenon that takes place after vapor gets into the storing room, along with the propulsion of time, in the relatively inclosed storing room, the condensation is constantly aggravated, finally lead to gathering a large amount of liquid water, condense into frost even, influence food quality (milden and rot with higher speed, etc.).
In order to overcome the above problems, in the electrolytic oxygen removing device 40 of the embodiment, the cooling condensation plate 210 can also maintain a certain low temperature by absorbing the cold energy on the cold source plate 230, so that the water vapor generated in the electrolytic bin 300 is re-condensed when flowing through the cooling condensation plate 210, thereby reducing the amount of the water vapor entering the storage compartment, effectively controlling the humidity of the storage compartment, and reducing the possibility of the frosting phenomenon of the storage compartment.
In addition, as mentioned above, a large amount of heat is often generated during the electrochemical reaction in the electrolytic cell 300, so that the temperature of the accommodating cavity 140 is higher than that of the storage chamber, and the heat may be transferred to the storage chamber through convection heat exchange, which causes the temperature of the storage chamber to rise, and is not favorable for controlling the temperature of the storage chamber. Because the cooling condensation plate 210 of the embodiment keeps a certain low temperature, the air in the accommodating cavity 140 is cooled after encountering the cooling condensation plate 210, that is, the heat generated by the electrolytic bin 300 is absorbed by the cooling condensation plate 210, thereby reducing the influence of the heat generated by the electrolytic bin 300 on the storage chamber.
Referring to fig. 7, fig. 7 is an enlarged view of a portion a of fig. 4. In some embodiments, the cooling condensation plate 210 is provided with a shielding portion 130 at each air inlet 212, each shielding portion 130 is arched towards a direction away from the cooling condensation plate 210, and each shielding portion 130 is configured to cover at least a portion of one air inlet 212 on a projection of the cooling condensation plate 210 so as to block the water vapor escaping from the electrolytic cell 300 from being discharged from the air inlet 212.
That is, the shielding portion 130 can shield the air inlet 212 from the space, so that the water vapor escaping from the electrolytic cell 300 can contact the shielding portion 130 when passing through the air inlet 212, and the water vapor is cooled and condensed after meeting the shielding portion 130, thereby further reducing the amount of the water vapor discharged out of the accommodating cavity 140.
Further, each shielding portion 130 is downwardly opened, so that water condensed on the shielding portion 130 may be outwardly dropped by gravity.
Furthermore, each shielding portion 130 can be further disposed on the air inlet surface of the cooling condensation plate 210 facing the storage compartment, and since the fluidity of the air is stronger, the air can bypass the shielding portion 130 to enter the air inlet 212 and then enter the storage compartment 140 in the process of flowing from the storage compartment to the storage compartment 140, so that the shielding portion 130 has less influence on the air to enter the storage compartment 140.
Referring to fig. 8, fig. 8 is a schematic view of the front case 110 of the electrolytic oxygen removal device 40 in the refrigerator 1 according to an embodiment of the present invention.
