[0039] Reference will now be made in detail to embodiments of the present invention, one or more examples of which are shown in the accompanying drawings. The various embodiments provided are intended to explain the present invention, rather than to limit the present invention. In fact, it is apparent to those skilled in the art that various modifications and variations may be made to the present invention without departing from the scope or spirit of the present invention. For example, a feature illustrated or described as a part of one embodiment may be used together with another embodiment to produce yet another embodiment. Therefore, the present invention is intended to cover such modifications and variations within the scope of the appended claims and their equivalents.

[0040] Refer to the following Figures 1 to 6 The refrigerator 1 of the embodiment of the utility model is described. The directions or positional relationships indicated by "inside", "outside", "upper", "lower", "top", "bottom", "horizontal", "vertical" and the like are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the utility model. In order to facilitate the illustration of the structure of the device, some drawings of the utility model are illustrated in perspective.

[0041] In the description of this embodiment, it should be understood that the term "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined. When a feature "includes or contains" one or some of the features it covers, unless otherwise specifically described, this indicates that other features are not excluded and may further include other features.

[0042] In the description of the present embodiment, the description with reference to the terms "one embodiment", "some embodiments", "some examples", "an example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0043] The utility model provides a refrigerator 1, Figure 1 1 is a schematic structural diagram of a refrigerator 1 according to an embodiment of the present invention. The refrigerator 1 of this embodiment should be understood in a broad sense, for example, it can be a storage device with a low-temperature preservation function such as a refrigerator 1, a freezer, a storage cabinet, etc.

[0044] The refrigerator 1 may generally include a housing 10 and an electrolytic deoxidation device 20, wherein a fresh-keeping compartment 13 is formed inside the housing 10 for storing poultry eggs to be preserved, such as chicken eggs, duck eggs, goose eggs, etc. The electrolytic deoxidation device 20 is connected to the fresh-keeping compartment 13, and is configured to absorb oxygen in the fresh-keeping compartment 13 and release oxygen to the external space of the fresh-keeping compartment 13, so that the oxygen content in the fresh-keeping compartment 13 is reduced to 7% to 11%, for example, 7%, 8%, 9%, 10%, 11%, etc.

[0045] By adopting the above structure, a low-oxygen atmosphere can be formed in the fresh-keeping chamber 13, which is beneficial to suppress the respiration of eggs and bacteria at the same time, slow down the decomposition of organic matter in eggs and the reproduction of bacteria, thereby extending the storage time of eggs and reducing the deterioration of eggs.

[0046] Figure 2 is a schematic structural diagram of an electrolytic deoxidation device 20 according to an embodiment of the utility model. Figure 3 is a schematic diagram of an electrolytic deoxidation device 20 according to an embodiment of the present invention, referring to Figure 2 and Figure 3 The electrolytic deoxidizer 20 may include a housing 21, a cathode plate 22 and an anode plate 23. The electrolytic deoxidizer 20 may be disposed in the fresh-keeping compartment 13, or an installation opening may be provided on the wall of the fresh-keeping compartment 13, and the electrolytic deoxidizer 20 may be snapped into the installation opening.

[0047] The shell 21 is roughly in the shape of a flat rectangular parallelepiped, and the side wall with the largest area (such as the bottom wall) of the shell 21 can be opened to form a connecting port 211, which is beneficial to increase the contact area between the cathode plate 22 of the electrolytic deoxidation device 20 and the fresh-keeping compartment 13.

[0048] The cathode plate 22 is disposed at the connection port 211 to define a liquid storage chamber 212 for containing electrolyte together with the shell 21, and is used to consume oxygen in the fresh-keeping compartment 13 through electrochemical reaction under the action of the electrolysis voltage. The cathode plate 22 is disposed at the connection port 211, and the cathode plate 22 has a waterproof and breathable function (such as a waterproof and breathable membrane). While sealing the liquid storage chamber 212, the cathode plate 22 can ensure airflow communication with the fresh-keeping compartment 13. For example, the oxygen in the fresh-keeping compartment 13 can undergo a reduction reaction at the cathode plate 22, that is: O2+2H2O+4e-→4OH-. The electrolyte contained in the liquid storage chamber 212 can be an acidic aqueous solution or an alkaline aqueous solution, for example, a 1-5 mol / L sodium hydroxide solution.

[0049] The anode plate 23 is disposed in the liquid storage chamber 212 and is used to provide reactants to the cathode plate 22 through an electrochemical reaction. The anode plate 23 and the cathode plate 22 are disposed in the liquid storage chamber 212 at intervals from each other. When powered, the anode plate 23 is used to provide reactants (e.g., electrons) to the cathode plate 22 through an electrochemical reaction and generate oxygen. For another example, the OH- generated by the cathode plate 22 can undergo an oxidation reaction at the anode plate 23 and generate oxygen, that is: 4OH-→O2+2H2O+4e-. An exhaust port 213 can also be provided on the shell 21 (such as the top wall), and oxygen can be discharged through the exhaust port 213.

[0050] The above examples of electrochemical reactions of the anode plate 23 and the cathode plate 22 are merely illustrative. Based on the understanding of the above embodiments, those skilled in the art should be able to easily change the type of electrochemical reaction, and these changes should fall within the scope of protection of the present utility model.

[0051] Furthermore, the electrolytic deoxygenation device 20 may also include a liquid replenishing box 24, a water pipe 25 and a water pump 26. The positions of the liquid replenishing box 24, the water pipe 25 and the water pump 26 may be arranged in a targeted manner according to actual needs. The liquid replenishing box 24 is filled with electrolyte, the water pipe 25 connects the liquid replenishing box 24 with the liquid storage chamber 212, and the water pump 26 is arranged on the water pipe 25. After the water pump 26 is started, the electrolyte in the liquid replenishing box 24 can be smoothly transported to the liquid storage chamber 212 to achieve liquid replenishment.

[0052] The fresh-keeping compartment 13 is a relatively closed space with good sealing performance, and the oxygen content therein can be manually set according to actual needs. When the user takes and places eggs, the fresh-keeping compartment 13 needs to be opened, which causes outside air to enter the fresh-keeping compartment 13. The nitrogen content in the outside air is about 78%, and the oxygen content is about 21%. The air entering the fresh-keeping compartment 13 will cause the oxygen content in the fresh-keeping compartment 13 to increase. At this time, the electrolytic deoxidation device 20 needs to be started to reduce the oxygen in the fresh-keeping compartment 13.

[0053] In one example, a gas sensor 30 is provided in the fresh-keeping compartment 13, and the gas sensor 30 can monitor the oxygen content in the fresh-keeping compartment 13. During the oxygen reduction process, the gas sensor 30 is used to monitor the oxygen content in the fresh-keeping compartment 13. When the oxygen content drops to a set content, such as 10%, the electrolytic deoxidation device 20 can be turned off to prevent the electrolytic deoxidation device 20 from working for a long time, resulting in too low oxygen content in the fresh-keeping compartment 13, causing hypoxia and necrosis of poultry eggs.

[0054] Poultry eggs contain microorganisms and enzymes that maintain life activities. During the experiment, it was found that when the storage temperature is -1℃~4℃, especially -1℃~0℃, the respiration of poultry eggs can be significantly reduced, the evaporation of water in the eggshell can be reduced, which is conducive to maintaining the nutritional value and freshness of poultry eggs. When the storage temperature is 10℃~20℃, poultry eggs will begin to change gradually; when the storage temperature is 21℃~25℃, the embryo of poultry eggs will begin to develop.

[0055] Too high a temperature will cause the ovules and yolks of poultry eggs to expand, the egg whites to become thinner, the water to evaporate, the air chambers to increase, and the weight to decrease, which will cause the poultry eggs to deteriorate and their nutritional value to decrease. At 9°C, the weight loss of a poultry egg (chicken egg) per day and night is about 1 mg. For every 10°C increase, the weight loss increases by more than 5 times. Too low a temperature will cause the eggshell to crack and the egg liquid to freeze. When the storage temperature is -2°C, the eggshell will crack and the egg liquid will ooze out. When the egg storage temperature is -7°C, the egg liquid begins to freeze.

[0056] In the embodiment of the utility model, the internal temperature of the fresh-keeping compartment 13 can be set to -1°C to 4°C, for example, -1°C, 0°C, 1°C, 2°C, 3°C, 4°C, etc., so as to provide optimal temperature conditions for the storage of poultry eggs.

[0057] In one example, the fresh-keeping compartment 13 has an air inlet 151, which is used to introduce a refrigerated airflow into the fresh-keeping compartment 13. The refrigerated airflow can be provided by the refrigeration system of the refrigerator 1. The internal temperature of the fresh-keeping compartment 13 is adjusted by the refrigerated airflow, so that the internal temperature of the fresh-keeping compartment 13 can be quickly reduced to -1°C to 4°C.

[0058] The surface of poultry eggs has a natural gelatinous film, which can protect the eggs from external pollutants such as environmental microorganisms. It is an important protective layer for the eggs themselves. It is easily damaged by moisture absorption, condensation, water washing, etc., which will cause the pores to be exposed, accelerate the entry of bacteria on the eggshell surface into the protein and reproduce, and accelerate corruption and deterioration.

[0059] In the embodiment of the utility model, the internal humidity of the fresh-keeping chamber 13 can be set to 75% to 85%, for example, 75%, 78%, 80%, 82%, 85%, etc., so as to provide the best humidity conditions for the storage of poultry eggs, maintain the eggshell surface dry and free of condensation, and prevent the environment from being too dry and accelerating the evaporation of water in the eggs.

[0060] In one example, the refrigerator 1 may further include a humidification module 40, which is disposed in the fresh-keeping compartment 13 or communicated with the fresh-keeping compartment 13 and configured to controllably adjust the internal humidity of the fresh-keeping compartment 13 so that the internal humidity of the fresh-keeping compartment 13 is 75% to 85%.

[0061] In other examples, the humidification module 40 may be arranged in the air duct of the refrigerator 1 or the gas path of the electrolytic deoxidizer 20 to humidify the fresh-keeping compartment 13. Alternatively, a moisture permeable film may be attached to the fresh-keeping compartment 13 to adjust the internal humidity of the fresh-keeping compartment 13 using the moisture permeable film.

[0062] In the actual preservation process, the eggs can be placed in the preservation chamber 13 first, and then the internal temperature and humidity of the preservation chamber 13 are adjusted by the refrigeration airflow and the humidification module 40, and finally the oxygen content of the preservation chamber 13 is adjusted by the electrolytic deoxidation device 20.

[0063] When poultry eggs breathe through their pores, if there are odor molecules in the surrounding environment, the odor molecules will contaminate the eggs and affect the edible quality of the eggs. Poultry eggs are natural culture media for bacteria. When contaminated by poultry feces, blood, egg liquid and other organic matter, the bacteria will first grow and multiply on the surface of the eggshell and gradually invade the egg through the pores. At a suitable temperature, the bacteria will multiply rapidly, accelerating the corruption and deterioration of poultry eggs.

[0064] In an embodiment of the utility model, the refrigerator 1 may further include a sterilization module 50, which may be disposed in the fresh-keeping compartment 13 or be in airflow communication with the fresh-keeping compartment 13, and configured to release sterilizing substances into the fresh-keeping compartment 13 in a controlled manner so as to purify the fresh-keeping compartment 13 using the sterilizing substances.

[0065] In one example, the sterilization module 50 may include a shell and an electrode group, wherein the shell is in the shape of a box, the interior of the shell defines a cavity, the electrode group is arranged in the cavity, and the electrode group includes an excitation electrode and a receiving electrode, and the excitation electrode and the receiving electrode are arranged at intervals. The excitation electrode is used to generate high-energy electrons, and the high-energy electrons can move in a directional manner under the action of the electric field and collide with air molecules, thereby generating an ion wind blowing toward one side of the receiving electrode. During the directional movement, the electrons can break up odor molecules, excite oxygen to produce ozone, and the excitation electrode can break down the cells of suspended organisms through high-voltage ionization discharge, thereby achieving sterilization and deodorization of the fresh-keeping compartment 13.

[0066] Of course, the above examples of the sterilization module 50 are merely illustrative. Based on the understanding of the above embodiments, those skilled in the art should be able to easily change the type of the sterilization module 50, and these changes should all fall within the protection scope of the present utility model.

[0067] Figure 4 1 is a schematic exploded view of a drawer body 14 and a drawer sleeve 15 according to an embodiment of the present utility model. Figure 5 is a schematic cross-sectional view of a drawer body 14 and a drawer sleeve 15 according to an embodiment of the utility model. Figure 6 It is a schematic structural diagram of a drawer body 14 and an egg shelf 16 according to an embodiment of the utility model.

[0068] In an optional embodiment, a drawer sleeve 15 and a drawer body 14 are embedded in the box body 10 of the refrigerator 1. The drawer sleeve 15 serves as the fresh-keeping liner of the refrigerator 1 and has a lateral opening. The drawer body 14 has a top opening. The drawer body 14 can be pushed and pulled in the drawer sleeve 15 through the lateral opening, and together with the drawer sleeve 15, defines a fresh-keeping compartment 13. The air inlet 151 can be set on the top wall of the drawer sleeve 15.

[0069] When the user takes and places the eggs, the convenience of taking and placing can be improved by pushing and pulling the drawer body 14. In addition, the space of the fresh-keeping chamber 13 defined by the drawer sleeve 15 and the drawer body 14 is small and can be dedicated to storing eggs, which is conducive to reducing the deoxygenation amount of the electrolytic deoxidation device 20 and reducing the fresh-keeping cost of the eggs.

[0070] Considering that poultry eggs are easily squeezed and collided during the process of pushing and pulling the drawer body 14, resulting in problems such as cracks in the eggshell, leakage or even loose yolk, which seriously affects the preservation quality of the poultry eggs, an egg rack 16 can be set in the drawer body 14, and the egg rack 16 has a plurality of egg trays 161, each of which can be used to store one poultry egg, and the egg tray 161 is used to independently protect the poultry eggs.

[0071] In an optional embodiment, a refrigerating compartment 11 or a freezing compartment 12 is further defined in the box body 10 of the refrigerator 1, and the electrolytic deoxidation device 20 is connected to the refrigerating compartment 11 or the freezing compartment 12, and the oxygen released by the electrolytic deoxidation device 20 is supplied to the refrigerating compartment 11 or the freezing compartment 12 to increase the oxygen content in the refrigerating compartment 11 or the freezing compartment 12.

[0072] In one example, an exhaust pipe 27 is connected to the exhaust port 213 of the electrolytic deoxidation device 20, and the outlet of the exhaust pipe 27 can be connected to the refrigerating compartment 11 and the freezing compartment 12 respectively, and a regulating valve 28 for switching the oxygen flow direction is provided on the exhaust pipe 27. In this way, when "oxygen-loving" food is stored in the refrigerating compartment 11 or the freezing compartment 12, the oxygen discharged from the electrolytic deoxidation device 20 can be transported to the refrigerating compartment 11 or the freezing compartment 12 accordingly to obtain a better storage effect.

[0073] Poultry eggs are living organisms that are constantly undergoing a series of physiological and biochemical activities. Temperature and humidity can cause changes in the quality of poultry eggs. The refrigerator 1 of the utility model can provide suitable temperature, humidity and oxygen content for the storage of poultry eggs, so that the poultry eggs stored in the fresh-keeping compartment 13 can achieve a better fresh-keeping effect.

[0074] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the contents disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all such other variations or modifications.
