technical field

The utility model relates to the technical field of refrigerator storage, in particular to a refrigeration and freezing device.

Background technique

A refrigerator is a refrigeration device that maintains a constant low temperature, and it is also a civilian product that keeps food or other items in a constant low temperature and cold state. With the improvement of the quality of life, consumers have higher and higher requirements for the preservation of stored food, especially for the color and taste of food. Therefore, the stored food should also ensure that the color, taste, and freshness of the food remain unchanged as much as possible during the storage period. At present, in order to better store food in the market, there is only one kind of vacuum preservation. Vacuum fresh-keeping methods that are often used are vacuum bag fresh-keeping and vacuum storage compartment fresh-keeping.

Fig. 5 is a schematic cross-sectional view of a gas separator in a refrigerating and freezing device according to an embodiment of the present invention. As shown in FIG. 5 , the gas separator 30 has a modified atmosphere membrane 300 , a first gas collection chamber 310 and a second gas collection chamber 320 . The atmosphere-modulating membrane 300 may be an oxygen-enriched membrane. The atmosphere-modulating membrane 300 is located between the first gas collection chamber 310 and the second gas collection chamber 320, and the inner surface of the atmosphere-modulating membrane 300 faces the second gas collection chamber 320, and the first gas collection chamber 310 is configured to be controlled and connected to the storage chamber. The air in the storage space 200 enters the first gas collection chamber 310 when the pressure of the first gas collection chamber 310 is lower than the pressure of the storage space 200. When the pressure of the collection chamber 310 is greater than the pressure of the second gas collection chamber 320, more oxygen in the air entering the first gas collection chamber 310 will pass through the atmosphere-modulating membrane 300 and enter the second gas collection chamber relative to the nitrogen therein. 320, to form oxygen-enriched gas in the second gas collection chamber 320, and the first gas collection chamber 310 is also configured to communicate with the controlled atmosphere fresh-keeping space 210, so that the pressure in the first gas collection chamber 310 is greater than the controlled atmosphere fresh-keeping space When the pressure of the space 210 is high, the rest of the gas that enters the first gas collection chamber 310 except the oxygen-enriched gas that has passed through the atmosphere-modified membrane 300 and entered the second gas collection chamber 320 enters the controlled-atmosphere fresh-keeping space 210, so that the air-conditioned fresh-keeping A gas atmosphere rich in nitrogen and deficient in oxygen is obtained in the space 210 to facilitate food preservation. The suction pump 41 communicates with the second gas collection chamber 320 via the pipeline 50 and is configured to force the gas in the second gas collection chamber 320 to flow out of the gas separator 30 .

The modified atmosphere membrane is permeable to all gases, but different gases have different degrees of permeability. It is a complicated process for gas to permeate the CA membrane. The mechanism of gas penetration is generally that the gas molecules are first adsorbed to the surface of the CA membrane and dissolved, then diffuse in the CA membrane, and finally desorbed from the other side of the CA membrane. . The modified atmosphere membrane separation technology relies on the difference in the dissolution and diffusion coefficients of different gases in the modified atmosphere membrane to achieve the separation of gases. In the present utility model, the atmosphere-modulating membrane 300 may be an oxygen-enriched membrane. Therefore, when the mixed gas is under a certain driving force (pressure difference or pressure ratio on both sides of the air-conditioning membrane), gases with relatively fast permeation rates such as oxygen, hydrogen, helium, hydrogen sulfide, carbon dioxide, etc. will pass through the air-conditioning membrane. After the membrane, it is enriched on the permeation side of the modified atmosphere membrane, and the gas with a relatively slow permeation rate such as nitrogen, carbon monoxide, etc. is retained on the retention side of the modified atmosphere membrane to be enriched so as to achieve the purpose of separation of mixed gases.

Those skilled in the art all know that normal air composition includes (by volume percentage, hereinafter the same): about 78% nitrogen, about 21% oxygen, about 0.939% rare gas (helium, neon, argon, krypton, xenon, radon), 0.031% carbon dioxide, and 0.03% other gases and impurities (eg, ozone, nitric oxide, nitrogen dioxide, water vapor, etc.). In the field of controlled atmosphere fresh-keeping, it is usually used to fill the closed space with nitrogen-rich gas to reduce the oxygen content to obtain a nitrogen-rich and oxygen-poor fresh-keeping gas atmosphere. Here, those skilled in the art know that nitrogen-enriched gas refers to a gas whose nitrogen content exceeds the nitrogen content in the above-mentioned normal air, for example, the nitrogen content may be 95% to 99%, or even higher; The gas atmosphere refers to a gas atmosphere in which the nitrogen content exceeds the nitrogen content in the above-mentioned normal air, and the oxygen content is lower than the above-mentioned oxygen content in the normal air.

Specifically, the air suction pump 41 makes the gas in the second gas collection chamber 320 flow out through the pipeline 50 by pumping air outward, thereby reducing the pressure of the second gas collection chamber 320 . When the pressure of the second gas collection chamber 320 is lower than the pressure of the first gas collection chamber 310, the gas such as oxygen with a relatively fast permeation rate in the air in the first gas collection chamber 310 enters the first gas collection chamber 310 under the action of the pressure and the atmosphere-modulating membrane 300. Two gas collection chambers 320. At this time, because part of the oxygen in the first gas collection chamber 310 enters the second gas collection chamber 320, other gases with a relatively slow permeation rate containing only a small amount of oxygen or no oxygen are formed in the first gas collection chamber 310, that is, It is a nitrogen-rich gas. Furthermore, the pressure of the first gas collection chamber 310 decreases due to the reduction of oxygen in the gas, so that the air in the storage space 200 enters the first gas collection chamber 310 due to the pressure difference, and is discharged by the air suction pump 41 and the air. Under the action of the adjustable membrane 300 , gases such as oxygen with a relatively fast permeation rate in the air entering the first gas collection chamber 310 are continuously discharged into the second gas collection chamber 320 . That is to say, the air suction pump 41 makes the air in the storage space 200 continue to enter the gas separator 30 by pumping air outwards, and under the action of the atmosphere-modulating membrane 300, forms in the first gas collection chamber 310 to remove the air that has entered the second gas separator. The rest of the gas in the gas collection chamber 320 is nitrogen-enriched gas. At this time, the first gas collection chamber 310 can be controlled to communicate with the modified atmosphere fresh-keeping space 210 , so that the nitrogen-enriched gas can be filled into the modified atmosphere fresh-keeping space 210 .

The refrigerating and freezing device 10 of the present utility model can form a nitrogen-rich and oxygen-poor gas atmosphere in the air-conditioning fresh-keeping space 210 of the storage space 200 to facilitate food preservation. The strength of oxygen respiration, while ensuring basic respiration, prevents anaerobic respiration of fruits and vegetables, so as to achieve the purpose of long-term preservation of fruits and vegetables.

In some embodiments of the present invention, the gas separator 30 may include a gas collection box 31 . The gas collection box 31 is provided with a horizontally placed support frame 32. The support frame 32 and the upper half of the gas collection box 31 jointly define a first gas collection chamber 310. The support frame 32 and the lower half of the gas collection box 31 The boxes together define a second gas collection chamber 320 . Further, the air-conditioning membrane 300 can be horizontally arranged on the support frame 32 .

In some embodiments of the present invention, the gas collecting box 31 may also be provided with three vent holes that can be opened in a controlled manner. The three vent holes can be respectively the first vent hole for allowing the air in the storage space 200 to enter the first gas collection chamber 310, and the second vent hole for making the nitrogen-enriched gas to be filled into the modified atmosphere fresh-keeping space 210 from the first gas collection chamber 310. A vent hole and a third vent hole for allowing the oxygen-enriched gas to flow out of the second gas collection chamber 320 .

That is to say, the first gas collection chamber 310 can communicate with the storage space 200 through the first vent hole. Specifically, when the pressure of the first gas collection chamber 310 is lower than the pressure of the storage space 200, the first ventilation hole is opened under control. At this time, the second vent hole is controlled to be closed, so that the pressure of the first gas collection chamber 310 is increased, and a large amount of nitrogen-rich gas is formed. It can be understood that the pressure of the first gas collection chamber 310 will continue to rise because gases with a relatively slow permeation rate such as nitrogen cannot pass through the atmosphere-modulating membrane 300 to enter the second gas collection chamber 320 in large quantities. When the pressure of the first gas collection chamber 310 is greater than or equal to the pressure of the storage space 200, the first vent hole can be closed in a controlled manner, and at this time the second vent hole can be opened in a controlled manner so that the air in the first gas collection chamber 310 A large amount of nitrogen-enriched gas flows to the controlled atmosphere fresh-keeping space 210. The third vent hole can be kept open when the first vent hole and/or the second vent hole are opened, so that the oxygen-enriched gas in the second gas collection chamber 320 can be sucked out by the air pump 41 in time, thereby promoting the storage space 200 The inner air continues to flow into the first gas collection chamber 310 .

In some embodiments of the present invention, the second ventilation hole can also be configured to be opened with a time delay. Specifically, when the first vent hole is opened, the second vent hole is opened after waiting for a preset time, so that sufficient nitrogen-rich gas is formed in the first gas collection chamber 310 .

In some embodiments of the present invention, the refrigerating and freezing device 10 may further include an axial flow fan 60 . The axial flow fan 60 can be arranged on the flow path from the first gas collection chamber 310 to the controlled atmosphere fresh-keeping space 210, configured to be activated in a controlled manner, and promote the removal of permeated gas from the gas entering the first gas collection chamber 310. The rest of the oxygen-enriched gas entering the second gas collection chamber 320 through the modified film 300 is accelerated to flow to the modified atmosphere fresh-keeping space 210 . Specifically, the axial flow fan 60 is set such that its air inlet faces the first gas collection chamber 310, and its air outlet faces the controlled atmosphere fresh-keeping space 210, so as to accelerate the flow of nitrogen-enriched gas flowing out of the first gas collection chamber 310 to the controlled atmosphere. Fresh-keeping space 210. Further, the axial flow fan 60 can be configured to be turned on when the second air hole is opened.

In some embodiments of the present invention, the gas separator 30 may be disposed inside the storage space 200 and located at the outer rear side of the drawer cylinder 22 . That is to say, the gas separator 30 can be independently and integrally arranged outside the modified atmosphere fresh-keeping space 210, so that it is easy to install and disassemble.

In some embodiments of the present invention, a plurality of air pressure balance holes 221 may be opened on the drawer cylinder 22 , and the storage space 200 and the modified atmosphere fresh-keeping space 210 are communicated through the plurality of air pressure balance holes 221 . The air pressure balance holes 221 may be millimeter-sized micro holes, for example, the diameter of each air pressure balance hole 221 is 0.1 mm to 3 mm. Setting a plurality of air pressure balance holes 221 can keep the pressure in the air-conditioned fresh-keeping space 210 from being too high. Specifically, when the pressure in the air-conditioned fresh-keeping space 210 is too high, a small amount of gas in the air-conditioned fresh-keeping space 210 can be balanced by air pressure. The hole 221 flows into the storage space 200 to prevent the pressure of the modified atmosphere fresh-keeping space 210 from being too high. When a small amount of gas flows out of the controlled atmosphere fresh-keeping space 210 , the nitrogen-rich and oxygen-poor gas atmosphere in the controlled-atmosphere fresh-keeping space 210 does not change, or the change is negligible.
