Food is an energy source for people to live and is important for people. For food storage, the main two aspects are heat preservation and fresh preservation, in general, the temperature has obvious influence on the microbial activity on food and the action of enzymes in the food, the food is delayed to deteriorate due to the reduction of the temperature, and the refrigerator is a refrigeration device for keeping the food or other articles at a constant low temperature and is a civil product for keeping the food or other articles at a constant low temperature and cold state.

Therefore, the stored food should also ensure that the color, mouthfeel, freshness, etc. of the food remain as unchanged as possible during storage. Therefore, users also put higher demands on the fresh-keeping technology of the refrigerator.
In particular, some consumers now have made special demands on fresh keeping of aquatic products, and fresh and living aquatic products are now widely visible even in inland regions deviating from coastal. However, fresh living aquatic products (e.g., live fish, live shrimp, live crab, etc.) undergo a series of physical, chemical and physiological changes in the body after being inactivated, which in the initial stage causes acidic coagulation of proteins and contraction of muscles, which in turn causes the muscles to lose extensibility and harden, and which in turn causes acidic coagulation of proteins and contraction of muscles, which in turn causes the muscles to lose extensibility and harden, and various microorganisms including spoilage microorganisms can infiltrate into muscle tissue through the crustaceans, stomach and intestinal glands, which causes spoilage. So people often need to cook as soon as they purchase these products.
Although the shelf life of the aquatic products can be prolonged by a low-temperature sterilization mode in the prior art, the living storage cannot be guaranteed. This brings great inconvenience to the consumer user, affecting the consumer's enjoyment of fresh and alive seafood.

Detailed Description
Through survival research on the aquatic products, it is found that the survival time of the aquatic products can be prolonged by increasing the oxygen concentration in the storage space. Therefore, in the transportation and vending process, some merchants can introduce oxygen into the package to avoid death of the aquatic products. The technical means used is to directly use an oxygen storage device (such as an oxygen tank) to introduce oxygen into the package.
However, this method is not suitable for general consumers, and the oxygen storage device is generally a pressure tank, and has high requirements for storage and use, and has a certain danger.
The refrigerating and freezing device adopts the air-conditioning membrane to realize the air-conditioning and activity-keeping subspace for keeping fresh aquatic products alive, wherein the working principle of the air-conditioning membrane (also called as an oxygen-enriched membrane) is that the air-conditioning membrane is driven by the pressure difference to ensure that oxygen in the air preferentially passes through the air-conditioning membrane by utilizing the different permeation rates when all components in the air pass through the air-conditioning membrane.
Those skilled in the art will appreciate that normal air components include (in volume percent, hereinafter the same): about 78% nitrogen, about 21% oxygen, about 0.939% noble gases (helium, neon, argon, krypton, xenon, radon), 0.031% carbon dioxide, and 0.03% other gases and impurities (e.g., ozone, nitric oxide, nitrogen dioxide, water vapor, etc.).
In this embodiment, the air conditioning film assembly is economically miniaturized and silenced, so that the air conditioning film assembly is suitable for small-sized refrigeration and freezing equipment such as refrigerators or portable storage devices, and oxygen is produced by using the air conditioning film to form a keep-alive gas atmosphere.
Fig. 1 is a schematic structural diagram of a storage device with fresh keeping and living storage function according to an embodiment of the present application. The storage device of the present embodiment may include a case 20, an air-conditioning membrane assembly 30, an air pump 40, and a sealed storage container 72.
The case 20 defines a storage space therein. The closed storage container 72 is disposed in the storage space. The enclosed storage container 72 may contain an air-conditioned keep-alive subspace 272.
The air conditioning membrane assembly 30 is disposed outside the airtight storage container, and may be disposed with the inside of the case 20 or may be disposed outside the case 20. The modified atmosphere membrane assembly 30 has at least one modified atmosphere membrane and an oxygen enriched gas collection chamber 38. The modified atmosphere membrane assembly 30 is configured such that oxygen in ambient air permeates through the modified atmosphere membrane into the oxygen-enriched gas collection chamber 38 more than nitrogen in ambient air, such that the oxygen concentration within the oxygen-enriched gas collection chamber 38 is substantially greater than the oxygen concentration in air.
The inlet end of the air pump 40 is communicated with the oxygen-enriched gas collecting cavity 38, and the exhaust end of the air pump 40 is connected with the airtight storage container 72. The pump 40 may draw gas from the oxygen-enriched gas collection chamber 38 and exhaust the gas to the modified atmosphere keep-alive sub-space 272, thereby creating a gas atmosphere within the modified atmosphere keep-alive sub-space 272 that is conducive to fresh keeping.
In this embodiment, the pump 40 pumps the oxygen-enriched gas from the oxygen-enriched gas collection chamber 38 to a pressure less than the pressure of the surrounding space of the gas-regulating membrane module 30, and the oxygen in the surrounding space of the gas-regulating membrane module 30 is allowed to enter the oxygen-enriched gas collection chamber 38, so that the pump 40 provides the power for the oxygen to enter the oxygen-enriched gas collection chamber 38. After the pump 40 is turned off, the modified atmosphere membrane module 30 stops preparing oxygen.
A gas detection device 282 may also be disposed within the modified atmosphere keep-alive subspace. The gas detection device 282 may be used to detect the concentration of oxygen within the modified atmosphere keep-alive subspace 272. The gas detection device 282 may use an oxygen concentration sensor. The oxygen concentration sensor may be a diaphragm galvanic cell type, an electrochemical type, a catalytic combustion type, a constant potential electrolytic type, or the like, and in some alternative embodiments, the gas detection device 282 may also use a gas analyzer for measuring the gas content in the gas-conditioning and keep-alive subspace 272, including the oxygen content, and may also include the nitrogen content, the carbon dioxide content, or the like.
The pump 40 may also be configured to be turned on and off based on the oxygen concentration within the modified atmosphere keep-alive subspace 272 to maintain the oxygen concentration within a preset oxygen concentration range. For example, after the oxygen concentration in the modified atmosphere keep-alive subspace 272 drops to a preset concentration threshold, the suction pump 40 is started to start supplying oxygen to the modified atmosphere keep-alive subspace 272. The concentration threshold may be configured according to the product to be protected, and is typically set to not less than 40%. In other embodiments, the measurement may be performed in advance according to the gas leakage rule of the gas conditioning keep-alive subspace 272, and the start-stop cycle of the pump 40 is correspondingly configured, so that the pump 40 is periodically started and shut down to maintain the oxygen concentration within the preset oxygen concentration range.
The storage device of the present embodiment may also be provided with a solenoid valve 151. The electromagnetic valve 151 is disposed on a pipeline between the airtight container 72 and the air pump 40, and is configured to be turned off when the air pump 40 is turned off, so as to ensure the airtight container 72 to be sealed. Alternatively, the solenoid valve 151 may be provided on the casing to be started and stopped simultaneously with the suction pump 40.
The air conditioning membrane assembly 30 may also include a support frame. The support frame is internally formed with an oxygen-enriched gas collection chamber 38 and at least a portion of the outer surface of the support frame is formed with a hollowed-out support structure. The gas conditioning membrane is laid on a hollowed-out support structure to close the oxygen enriched gas collection chamber 38. The support frame has an air extraction aperture formed therein for connection to the oxygen enriched gas collection chamber 38 for connection to the inlet end of the pump 40.
The support frame may have various shapes such as a polyhedron, a sphere, and a plate. In order to secure the supporting strength and to reduce the space occupied by the air-conditioning membrane module 30, a flat plate-shaped air-conditioning membrane module 30 may be used. Fig. 2 is an exploded view of an air-conditioning membrane assembly 30 in a storage device having fresh and keep-alive storage function according to an embodiment of the present application.
The air conditioning membrane assembly includes a support frame 32 and an air conditioning membrane 36 disposed on the support frame 32. One or more air conditioning membranes 36 may be formed as an air conditioning membrane layer outside of the support frame 32. The permeation of gas through a gas-regulating membrane is a complex process, and the permeation mechanism is generally that gas molecules are firstly adsorbed to the surface of the gas-regulating membrane to be dissolved, then diffused in the gas-regulating membrane, and finally desorbed from the other side of the gas-regulating membrane. The gas-regulating membrane separation technology relies on the difference of dissolution and diffusion coefficients of different gases in a gas-regulating membrane to realize gas separation. When the gas is enriched in the permeate side of the modified atmosphere membrane 36 due to the pressure differential across the modified atmosphere membrane 36, oxygen having a fast permeation rate is concentrated in the oxygen-enriched gas collection chamber 38.
The support frame 32 may include a frame, ribs and/or plates disposed within the frame, and the like, between the ribs and the plates, and the like may define air flow channels, and grooves may be formed in the surfaces of the ribs and the surfaces of the plates to define the air flow channels. The ribs and/or plates may increase the structural strength of the air conditioning membrane assembly 30, etc.
For example, the support frame 32 has a first surface and a second surface parallel to each other, and the support frame 32 is formed with a plurality of air flow passages extending over the first surface, over the second surface, and through the support frame 32 to communicate the first surface and the second surface, respectively. That is, the plurality of air flow passages includes a plurality of first air flow passages extending over the first surface, a plurality of second air flow passages extending over the second surface, and a plurality of third air flow passages extending through the support frame 32 to communicate the first surface and the second surface. Alternatively, it is also understood that the support frame 32 is formed with a plurality of first air flow passages extending over the first surface and a plurality of second air flow passages extending over the second surface, and that the first air flow passages and the second air flow passages are in communication with each other through the third air flow passages. All of the gas flow channels collectively form an oxygen-enriched gas collection chamber 38.
The one or more air regulating membranes 36 form two planar air regulating membrane layers which are respectively laid on the first surface and the second surface of the support frame, thereby forming the planar air regulating membrane assembly 30.
In some embodiments, the support frame 32 includes an air extraction aperture 33 in communication with the air flow passage, the air extraction aperture 33 being in communication with the oxygen-enriched gas collection chamber 38 for connecting to the inlet end of the air extraction pump 40, thereby allowing the oxygen-enriched gas in the oxygen-enriched gas collection chamber 38 to be output. When the air pump 40 is operated, the oxygen-enriched gas collecting cavity 38 is in a negative pressure state, and oxygen in the air outside the air conditioning membrane assembly 30 continuously passes through the air conditioning membrane 36 and enters the oxygen-enriched gas collecting cavity 38. The support frame 32 may be generally rectangular in overall shape.
In some embodiments, the support frame 32 may include: the frame, a plurality of first floor and a plurality of second floor. The first rib plates are arranged at intervals in the longitudinal direction and extend in the transverse direction in the frame, and one side surface of the first rib plates forms a first surface. The plurality of second rib plates are arranged at intervals along the transverse direction on the other side surface of the plurality of first rib plates and extend along the longitudinal direction, and the second surface is formed on the side surface of the plurality of second rib plates, which is far away from the first rib plates. That is, the plurality of second ribs are provided on one side surface of the plurality of first ribs. The surfaces of the first rib plates and the second rib plates, which are opposite, respectively form a first surface and a second surface; that is, the surfaces of the plurality of first ribs and the plurality of second ribs facing each other form a first surface; the surfaces of the second rib plates and the first rib plates opposite to each other form a second surface. Gaps between adjacent first ribs, between adjacent second ribs, and between adjacent first and second ribs form the aforementioned plurality of air flow passages. Wherein the gaps between two adjacent first ribs form a first air flow channel extending over the first surface, the gaps between two adjacent second ribs form a second air flow channel extending over the second surface, and the gaps between adjacent first and second ribs form a third air flow channel extending through the support frame 32 communicating the first and second surfaces. That is, the intersecting structure formed by all the first ribs and all the second ribs forms the aforementioned plurality of air flow passages.
The support frame 32 is provided with a plurality of first ribs which are longitudinally spaced and transversely extending and a plurality of second ribs which are transversely spaced and longitudinally extending on one side surface of the plurality of first ribs, so that the continuity of the air flow channel is ensured, the volume of the support frame is greatly reduced, and the strength of the support frame 32 is greatly enhanced. In addition, the above structure of the support frame 32 ensures that the air-conditioning membrane 36 can be sufficiently supported, and can always maintain good flatness even under the condition of large negative pressure in the oxygen-enriched gas collection cavity, thereby ensuring the service life of the air-conditioning membrane assembly 30.
The air suction hole 33 may be provided at one lateral side of the frame in the middle of the longitudinal direction of the frame. This arrangement corresponds to the extraction of air from the middle of the air conditioning membrane assembly 30, which is advantageous for uniform ventilation of the air conditioning membrane 36. The suction hole 33 may be a stepped hole or a stepped hole to ensure the air tightness of the connection portion when it is connected to the suction pump 40 through a hose.
For further convenience of installation, the air-conditioning film 36 may be first mounted to the frame by a ring of double-sided tape 34 and then sealed by a ring of sealant 35. In some embodiments, both side surfaces of the circumferential inner side of the frame are recessed flush with the first surface and the second surface, respectively, to form one mounting groove in each of the both side surfaces of the frame, and each of the air conditioning films 36 is embedded in one of the mounting grooves. The two side surfaces of the frame are respectively sunk in the periphery of the mounting groove to form a circle of annular grooves for filling the sealant 35 so as to sealingly mount the air conditioning film 36 in the mounting groove. Thereby, the air-conditioning membrane 36 can be conveniently, quickly and reliably arranged on the supporting frame 32, the air tightness of the air-conditioning membrane assembly 30 is ensured, and a sufficient pressure difference can be formed between the inside and the outside of the air-conditioning membrane assembly 30.
In the storage device with fresh keeping and alive keeping functions of the present embodiment, in order to improve the efficiency of supplying oxygen to the closed storage container 72, a plurality of air-conditioning membrane modules 30 may be arranged at the same time as required, and oxygen in the oxygen-enriched gas collecting chambers 38 in the plurality of air-conditioning membrane modules 30 may be pumped by the air pump 40 at the same time.
The storage device of the embodiment may be a portable storage dish or a refrigeration and freezing device such as a refrigerator, for example, the storage device of the embodiment may also be provided with a refrigeration system for supplying cold to the storage space, so that the storage device forms the refrigeration and freezing device, and the storage space at least includes a refrigeration chamber 27 forming a refrigeration storage environment; a closed storage container 72 is provided in the refrigerating chamber 27.
Fig. 3 is a schematic structural view of a case 20 when the storage device having a fresh keeping and alive storing function is used as a refrigerating and freezing device according to an embodiment of the present application. The case 20 defines therein a storage space which may be configured as a refrigerating chamber 27, a freezing chamber 25, a temperature changing chamber 26, and the like according to a refrigerating temperature. The refrigerating and freezing apparatus may be a refrigerator having at least a refrigerating chamber 27 and a freezing chamber 25. The refrigeration system may be a conventional compression refrigeration system or a semiconductor refrigeration system, or the like, that provides refrigeration to the storage compartment, for example, in the form of direct cooling and/or air cooling, to provide the storage compartment with a desired storage temperature. In some embodiments, the preservation temperature of the refrigerator compartment 27 may be 2-9 ℃, or may be 4-7 ℃; the preservation temperature of the freezing chamber 25 may be-22 to-14 deg.c, or may be-20 to 16 deg.c. The freezing chamber 25 is disposed below the refrigerating chamber 27, and the temperature changing chamber 26 is disposed between the freezing chamber 25 and the refrigerating chamber 27. The temperature in freezer compartment 25 typically ranges from-14 c to-22 c. The variable temperature chamber 26 can be adjusted as needed to store the appropriate food.
The closed storage container 72 may be disposed within any of the compartments described above.
