In some embodiments of the present invention, the storage container 10 may further include an oxygen enrichment membrane assembly 400. The space around the oxygen-enriched membrane module 400 can be communicated with the modified atmosphere fresh-keeping space in the cylinder 100, and the oxygen-enriched membrane module 400 can have at least one oxygen-enriched membrane 410 and an oxygen-enriched gas collection chamber 420, so that more oxygen in the air flow around the oxygen-enriched membrane module 400 can penetrate through the oxygen-enriched membrane 410 and enter the oxygen-enriched gas collection chamber 420 than nitrogen in the air flow. Specifically, the inner side surface of each oxygen enrichment membrane 410 faces the oxygen enrichment gas collection chamber 420 to allow oxygen in the air of the space outside the oxygen enrichment membrane assembly 400 to permeate more through the at least one oxygen enrichment membrane 410 into the oxygen enrichment gas collection chamber 420 than nitrogen therein when the pressure of the oxygen enrichment gas collection chamber 420 is less than the pressure of the surrounding space of the oxygen enrichment membrane assembly 400. The storage container 10 of this embodiment can make and form rich nitrogen poor oxygen in the fresh-keeping space of gas conditioning and do benefit to the fresh-keeping gas atmosphere of food, and this gas atmosphere reduces the intensity of fruit vegetables aerobic respiration through reducing the content of oxygen in the fruit vegetables save space, guarantees basic respiration simultaneously, prevents that fruit vegetables from carrying out anaerobic respiration to reach the purpose that fruit vegetables are fresh-keeping for a long time. In combination with the arrangement of the sealing ring 300, when the oxygen in the storage container 10 enters the oxygen-enriched gas collection cavity 420 and the internal pressure of the storage container 10 is lower than the external pressure, a certain amount of gas is supplemented from the gap of the contact part 330 in time to enter the storage container 10, so as to maintain the balance of the internal and external pressures of the storage container 10, thereby preventing the oxygen from entering the oxygen-enriched gas collection cavity 420 due to the too small pressure in the storage container 10, and improving the performance of the oxygen-enriched membrane assembly 400.
In some embodiments of the present invention, the oxygen-enriched membrane assembly 400 may have a flat plate shape and may be horizontally disposed on the top wall of the cartridge 100.

The micropores may also be referred to as air pressure balance holes, and each micropore may be a millimeter-sized micropore, for example, each micropore having a diameter of 0.1mm to 3 mm. The arrangement of the plurality of micropores can prevent the pressure in the modified atmosphere preservation space from being too low, and the arrangement of the plurality of micropores can not make nitrogen in the modified atmosphere preservation space flow to a large storage space, so that the nitrogen flows very little or even negligibly, and the preservation of food in the modified atmosphere preservation space can not be influenced.
In some embodiments of the present invention, a locking device, a handle, and a handle positioning device are provided between the drawer 200 and the cartridge 100. The locking device includes pivoting latches disposed on both sides of the drawer end cover, two buckling parts disposed on the barrel 100, and a clamping urging device. Each of the fastening portions may be a protrusion. The clamping promoting device can be used for promoting the two pivoting lock catches to rotate towards the direction of clamping the two pivoting lock catches to the corresponding buckling parts (namely the first directions). The handle extends horizontally and can be slidably mounted on the drawer end cover along the vertical direction. Also, the position of the handle when the drawer 200 is in the closed state may be an initial position of the handle. And the handle is configured such that, in its initial position, both ends of the handle respectively abut against the two pivoting latches to prevent each pivoting latch from rotating in another direction opposite to the respective first direction, so that the pivoting latches maintain the engagement with the catching portions, thereby locking the drawer 200 to the main body 100. Further, after the handle is moved up or down to the release-holding-locking position, i.e., from the initial position to the release-holding-locking position, each of the pivoting latches may be allowed to rotate in another direction opposite to the respective first direction, to allow the pivoting latch to rotate out of the respective engaging portion when the drawer 200 is pulled outward, thereby allowing the drawer 200 to be opened. The handle positioning device is configured to maintain the handle in various predetermined positions after the handle is moved to the positions, primarily the initial position and the unlocked position. When opening the drawer 200, the user first moves the handle up or down to the release holding position, the handle positioning means holds the handle in this position, and the user can pull the drawer 200 outward. When closing the drawer 200, the user first closes the drawer 200 and then returns the handle to the original position downward or upward, and the handle positioning means maintains the handle at that position, thereby maintaining the drawer 200 and the cartridge 100 in the locked state.
In order to further stabilize the movement of the handle, two ends of the handle are respectively provided with a guide rod and a slide block, and the guide rods extend in the vertical direction. The drawer 200 further includes two sets of slides, each set of slides having at least three vertically extending slide slots, such that two sides of the guide rod have one slide slot, respectively, and the slide block moves on the remaining slide slots, or two sides of the slide block have one slide slot, respectively, and the guide rod moves on the remaining slide slots. For example, each set of slide way may include four slide grooves, one slide groove is provided on each of the front and rear sides of the guide bar, and one slide groove is provided on each of the lateral sides (i.e., the left and right sides) of the slide block.
Fig. 3 is a schematic structural view of a refrigerator according to one embodiment of the present invention. As shown in fig. 3, an embodiment of the present invention also provides a refrigerator, which may include a cabinet, and a storage space may be defined in the cabinet. The refrigerator can also comprise the storage container 10 of any embodiment, which is arranged in the storage space. Specifically, a storage space and a compressor compartment may be defined within the case. For example, the case may include an inner container defining a storage space therein. The main door body is rotatably installed on the box body and configured to open or close a storage space defined by the box body. Further, a storage container 10 is arranged in the storage space, and a modified atmosphere fresh-keeping space is arranged in the storage container 10. The air-conditioning fresh-keeping space can be a closed space or an approximately closed space. Preferably, the storage container 10 is a drawer assembly. The refrigerator may further include a refrigeration system, which may be a refrigeration cycle system composed of a compressor, a condenser, a throttle device, an evaporator, and the like. The compressor is installed in the compressor storehouse. The evaporator is configured to directly or indirectly provide cooling energy into the storage space. For example, when the refrigerator is a household compression type direct cooling refrigerator, the evaporator may be disposed outside or inside the rear wall surface of the inner container. When the refrigerator is a household compression type air-cooled refrigerator, an evaporator chamber is further arranged in the refrigerator body and is communicated with the storage space through an air path system, an evaporator is arranged in the evaporator chamber, and a fan is arranged at an outlet of the evaporator chamber to perform circulating refrigeration on the storage space.
In some embodiments of the present invention, the refrigerator may include a suction pump. The air pump may be disposed in the compressor compartment, and an inlet end of the air pump is connected to the oxygen-enriched gas collection chamber 420 of the oxygen-enriched membrane module 400 via a pipeline, and is configured to pump air outwards via the oxygen-enriched membrane module 400, so as to controllably make the pressure of the oxygen-enriched gas collection chamber 420 smaller than the pressure of the controlled atmosphere fresh-keeping space. That is, the air pump is configured to pump the air in the controlled atmosphere fresh-keeping space outwards through the oxygen-enriched membrane assembly 400, so that the air in the controlled atmosphere fresh-keeping space flows to the air-enriched membrane assembly 400, and under the action of the oxygen-enriched membrane assembly 400, part or all of the oxygen in the air in the controlled atmosphere fresh-keeping space enters the oxygen-enriched air collecting cavity 420 and then is discharged out of the controlled atmosphere fresh-keeping space through the pipeline and the air pump, so that the nitrogen-rich and oxygen-poor gas atmosphere in the controlled atmosphere fresh-keeping space is obtained to facilitate the food fresh-keeping. With the sealing ring 300 of the above embodiment, the pressure inside and outside the container 10 can be kept balanced as much as possible, so that the air pump can more easily pump oxygen from the oxygen-enriched gas collection chamber 420, and the energy consumption of the air pump is reduced.
