If there is a description of first and second for the purpose of distinguishing technical features only, this is not to be understood as indicating or implying a relative importance or implicitly indicating the number of technical features indicated or implicitly indicating the precedence of 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 40 is arranged in the compartment 20, and the storage device 40 can further keep the food materials fresh. Referring to fig. 2, the storage device 40 according to an embodiment of the present invention includes the oxygen removing assembly 10, and the oxygen removing assembly 10 is communicated with the storage space 410 in the storage device 40 and can treat oxygen in the storage space 410, so as to reduce the oxygen content in the storage space 410 and further improve the fresh-keeping effect of the storage device 40.
Referring to FIG. 4, an oxygen scavenging assembly 10 according to one embodiment of the present invention, for use in a refrigerator, includes an oxygen scavenging module 100. Specifically, deoxidization module 100 adopts the electrochemistry principle, will enter into the oxygen of deoxidization module 100 through electrode and electrolyte and carry out redox reaction to replace and discharge oxygen. It can be understood that, when the gas in the storing space 410 contacts with the deoxidization module 100, deoxidization module 100 has the ventilated membrane (not shown in the figure) with storing space 410 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 410, make storing space 410 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 410, make other gaseous equilibrium states that form. Therefore, the oxygen removal module 100 can adjust the gas component ratio in the storage space 410, so as to obtain an environment rich in nitrogen and poor in oxygen, which is beneficial to keeping food materials in the storage space 410 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 process of after-ripening and aging 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 sealingly connected to at least a portion of the cover plate 210, as shown in fig. 5 and 6, a separating chamber 230 is formed between at least a portion of the cover plate 210 and the top cover 220, an air overflow port 211 and a return pipe 212 are provided on the cover plate 210, the air overflow port 211 communicates the reservoir 110 and the separating chamber 230, and the air overflow port 211 is located above the liquid level of the electrolyte to discharge the mixture in the reservoir 110 to the separating chamber 230. It will be appreciated that the mixture in the reservoir 110 is accumulated to a certain extent and then discharged from the air overflow vent 211 by the air pressure, because the outlet of the air overflow vent 211 is communicated with the separation chamber 230, the area of the outlet of the air overflow vent 211 is suddenly increased, according to the flow formula: q (flow rate) ═ V (flow velocity) × S (passage area), when the flow rate is constant, the passage area increases, the flow velocity of the gas decreases, and therefore the electrolyte droplets fall under the action of gravity, and are separated from the oxygen and water vapor streams, one end of the return pipe 212 communicates with the separation chamber 230, and the other end is located below the electrolyte liquid surface, so that the separated electrolyte droplets flow back into the reservoir chamber 110 through the return pipe 212. 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. It is further explained that the top cover 220 is provided with an exhaust port 221 communicated with the separation cavity 230, and the separated 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 410 is ensured, and the fresh-keeping effect of the storage space 410 is improved. In addition, 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 cavity 110 can be prevented from being discharged through the return pipe, and the gas-liquid separation effect of the gas overflow port 211 can be prevented from being influenced.
