If the first and second are described for the purpose of distinguishing technical features, they are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of the technical features indicated.

In the description of the present invention, unless otherwise specifically limited, terms such as set, installation, connection and the like should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above terms in the present invention by combining the specific contents of the technical solutions.

Referring to fig. 1, a refrigerator according to an embodiment of the present invention may be understood as a broad type of refrigeration storage device, including but not limited to, a refrigerator, an ice chest, and a freezer. The refrigerator of the embodiment comprises a compartment 20 for storing food materials, wherein a storage device 30 is arranged in the compartment 20, and the storage device 30 can further keep the food materials fresh. Referring to fig. 2, the storage device 30 according to an embodiment of the present invention includes an oxygen removing assembly 10, wherein the oxygen removing assembly 10 is in communication with the storage space 310 inside the storage device 30 and can treat oxygen inside the storage space 310, so as to reduce the oxygen content inside the storage space 310 and further improve the freshness-keeping effect of the storage device 30.

Referring to fig. 4, an oxygen scavenging assembly 10 according to one embodiment of the present invention, which is used in a refrigerator, includes an oxygen scavenging module 100. Specifically, the oxygen removal module 100 adopts the electrochemical principle, and oxygen entering the oxygen removal module 100 is subjected to oxidation-reduction reaction through electrodes and electrolyte, so that the oxygen is replaced and discharged. It can be understood that, when the gas in the storing space 310 contacts with the deoxidization module 100, deoxidization module 100 has a ventilated membrane (not shown in the figure) with storing space 310 intercommunication department, oxygen in the air enters into the electrolyte of deoxidization module 100 through the ventilated membrane, deoxidization module 100 consumes the oxygen in the storing space 310, make storing space 310 form the state of low oxygen negative pressure, oxygen constantly permeates to the electrolyte through the ventilated membrane, and deoxidization module 100 does not consume other gases (nitrogen is main) except oxygen in the air in the storing space 310, make other gaseous equilibrium states that form. Therefore, the oxygen removal module 100 can adjust the gas component ratio in the storage space 310, so as to obtain an environment rich in nitrogen and poor in oxygen, which is beneficial to keeping food materials in the storage space 310 fresh. Further, the environment rich in nitrogen and poor in oxygen can effectively inhibit the respiration of fruits and vegetables, reduce the consumption of organic substances, and can also make the cells of the fruits and vegetables slowly breathe, maintain the vitality of the cells and keep the excellent quality and the fragrant smell of the fruits and vegetables; but also can effectively inhibit the breeding of aerobic bacteria and anaerobic bacteria and prevent microorganisms from rotting fruits and vegetables. In addition, the environment rich in nitrogen and oxygen can also inhibit the activity of certain enzymes, inhibit the generation of ethylene, delay the after-ripening and aging process and keep the nutrition of the fruits fresh for a long time.

Referring to fig. 4 and 5, in the oxygen removal module 10 according to one embodiment of the present invention, a reservoir chamber 110 for storing electrolyte is defined in the oxygen removal module 100, oxygen is displaced from the reservoir chamber 110 through electrodes and the electrolyte, oxygen bubbles are formed in the electrolyte, and the oxygen bubbles are broken at the electrolyte level to overflow above the electrolyte level to form a mixture, wherein the mixture at least comprises oxygen, electrolyte droplets, water vapor and the like.

It is further noted that the oxygen removing assembly 10 of the embodiment of the present invention further includes a separating structure 200, the separating structure 200 includes a cover plate 210 for sealing the reservoir 110, and a top cover 220 connected to at least a portion of the cover plate 210 in a sealing manner, as shown in fig. 5 and 6, a separating cavity 230 is formed between at least a portion of the cover plate 210 and the top cover 220, an air overflow opening 211 is provided on the cover plate 210, the air overflow opening 211 communicates the reservoir 110 and the separating cavity 230, and the air overflow opening 211 is located above the liquid level of the electrolyte to discharge the mixture in the reservoir 110 to the separating cavity 230. It will be understood that the mixture in the reservoir 110 is discharged from the overflow port 211 by the air pressure after being accumulated to a certain extent, because the outlet of the overflow port 211 is communicated with the separation chamber 230, the area of the outlet of the overflow port 211 is suddenly increased, according to the flow formula: when the flow rate is constant, the passage area increases and the flow rate of the gas decreases, so that the electrolyte droplets fall by gravity and are separated from the oxygen and water vapor streams. In addition, the air overflow port 211 may have a through hole structure, a tubular structure, or the like, and is not particularly limited herein.

Referring to fig. 6, the cover plate 210 is provided with one or more partitions 240 at intervals in the extending direction, the partitions 240 are provided with one or more partitions 240, the partitions 240 extend towards the top cover 220 so that the separating chamber 230 forms a plurality of separate compartments 231, the partitions 240 are provided with compression pipes 241 so that adjacent compartments 231 are communicated, the adjacent compartments 231 are sealed with each other and are communicated only through the compression pipes 241, when the mixture in the compartments 231 is accumulated to a sufficient pressure, the mixture is compressed and enters the next compartment 231 along the airflow path through the compression pipes 241, and the outlet area of the airflow is suddenly increased when the mixture is discharged from the outlet of the compression pipes 241, according to the flow formula: when the flow rate is constant, the passage area increases, the flow rate of the gas decreases, and the mixture is separated again into gas and liquid, so that the oxygen gas flow can be further separated from the electrolyte droplets and the water vapor. In addition, each separation chamber 231 is connected with a return pipe 212, and the lower ends of the return pipes 212 are located below the electrolyte level, so that separated electrolyte droplets flow back to the liquid storage chamber 110 through the return pipes 212.

It can be understood that, when the mixture passes through the structure of the plurality of separation chambers 231 and the compression pipes 241 on the flow path of the mixture in the separation chamber 230, the mixture is subjected to gas-liquid separation for a plurality of times, the oxygen is separated more thoroughly, most of the electrolyte droplets and the water vapor flow back into the oxygen removal module 100 through the return pipe 212, the top cover 220 is provided with the exhaust port 221, and the oxygen is discharged outwards through the exhaust port 221, so that the loss of the electrolyte in the oxygen removal module 100 can be effectively reduced, the processing capacity of the oxygen removal assembly 10 on the oxygen in the storage space 310 is ensured, and the fresh-keeping effect of the storage space 310 is improved; the gas outlet 221 and the gas overflow port 211 are respectively located in different compartments 231, so that the mixture discharged from the gas overflow port 211 is prevented from being discharged from the gas outlet 221 without being compressed and amplified by the compartments 231, and the effect of gas-liquid separation is prevented from being influenced. It should be noted that the lower end of the return pipe 212 is located below the liquid level of the electrolyte, so that the mixture in the liquid storage chamber 110 is prevented from being discharged through the return pipe, and the gas-liquid separation effect of the gas overflow port 211 is prevented from being affected.

In some embodiments of the present invention, further, the gas overflow port 211 and the gas exhaust port 221 are respectively located at two opposite ends of the separation chamber 230, so that the mixture discharged from the gas overflow port 211 can pass through all the compartments 231 along the gas flow path in the separation chamber 230, so that the oxygen in the mixed gas flow can be completely separated and then discharged from the gas exhaust port 221, thereby further increasing the backflow amount of the electrolyte and reducing the loss of the electrolyte in the oxygen removal module 100.

Still further, one or more compression pipes 241 may be disposed on each partition 240, and the number of the compression pipes 241 on each partition 240 is designed according to actual needs and is not limited in detail herein. It should be noted that, the projections of the compression pipes 241 on the adjacent partition plates 240 are staggered in the direction parallel to the partition plates 240, so that all the compression pipes 241 on the two adjacent partition plates 240 are spaced apart from each other, and it is ensured that the mixture discharged from the outlets of the compression pipes 241 can be sufficiently separated into gas and liquid in each compartment 231, so that the separated electrolyte droplets and water vapor can flow into the return pipe 212 along the inner wall of the compartment 231, thereby preventing the mixture from entering the next compression pipe 241 for compression without sufficient gas and liquid separation, and improving the separation effect of each compression pipe 241 and the compartment 231 on the mixture.

Referring to fig. 6, in some embodiments of the invention, the compression tube 241 has an inner diameter D that satisfies: d is more than or equal to 2mm and less than or equal to 10 mm. The inner diameter D of the compression pipe 241 may be designed to be 2mm, 5mm, 8mm or 10mm, etc., which have a better gas-liquid separation effect on the mixture, and the specific inner diameter is not limited thereto. It can be understood that when the value of the inner diameter D is too small, the compression pipe 241 is difficult to process and costly, but the compression effect is not greatly improved; when the value of the inner diameter D is too large, the degree of compression of the mixture in the compression pipe 241 is small, and the effect of gas-liquid separation at the outlet of the compression pipe 241 is poor.

Referring to fig. 6, in some embodiments of the invention, the compression tube 241 has a length L that satisfies: L/D is more than or equal to 2 and less than or equal to 3. The length L of the compression pipe 241 may be 2 times, 2.5 times or 3 times the inner diameter D, and the like, and all have a better gas-liquid separation effect on the mixture, and the specific inner diameter is not limited in detail here. It can be understood that when the ratio of the length L to the inner diameter D is too small, the compression effect of the mixture is deteriorated when passing through the compression pipe 241, affecting the effect of gas-liquid separation at the outlet of the compression pipe 241; when the ratio of the length L to the inner diameter D is too large, the mixture is easily discharged at the outlet of the compression pipe 241 and directly enters the next compression pipe 241, resulting in poor gas-liquid separation.

Referring to fig. 6, in some embodiments of the present invention, a flow guide plate 213 is formed in each compartment 231 of the cover plate 210, the flow guide plates 213 are arranged in an inclined downward manner, and the plurality of return pipes 212 are respectively and correspondingly connected to the plurality of flow guide plates 213, so that after a mixture discharged from the gas overflow port 211 or the compression pipe 241 is subjected to gas-liquid separation in each compartment 231, electrolyte droplets fall to the surface of the flow guide plate 213 under the action of gravity, and the electrolyte droplets are accumulated on the surface of the flow guide plate 213 and then return to the liquid storage chamber 110 through the corresponding return pipe 212, thereby improving the efficiency of electrolyte return.
