Referring to fig. 3, 4 and 7, the fresh-keeping chamber 1 can be provided with an air inlet 5 and an air outlet 6, the modified atmosphere film 2 is hermetically arranged at the air inlet 5, and the air inlet of the suction device 3 is communicated with the air outlet 6, so that the air in the modified atmosphere space 4 can be discharged from the air outlet 6. The air in the controlled atmosphere fresh-keeping space 4 is discharged from the air outlet 6, and simultaneously, the outside air can only enter the controlled atmosphere fresh-keeping space 4 after being isolated from oxygen by the controlled atmosphere film 2 and can not directly enter the controlled atmosphere fresh-keeping space 4, so that the time for the controlled atmosphere fresh-keeping space 4 to reach the required oxygen concentration value is shortened, the running time of the suction device 3 is shortened, the resources are saved, and the cost is reduced.

Referring to fig. 1, since the temperature of the fresh food compartment 1 is generally higher than that of the low-temperature storage compartment, if the gas exhausted from the modified atmosphere fresh food space 4 directly enters the low-temperature storage compartment, the storage effect of the low-temperature storage compartment is affected, and therefore, the exhaust port of the suction device 3 can be communicated with the outside of the refrigerator. Therefore, the gas exhausted from the air-conditioning preservation space 4 can be directly exhausted to the outside of the refrigerator, and the storage effect of the low-temperature storage chamber cannot be influenced.

The suction device 3 can be arranged at a plurality of positions, and for example, the suction device 3 can be positioned inside the fresh food compartment 1; as a further example, with reference to fig. 2, the suction device 3 may also be located inside the compressor compartment or in an area outside the freshener chamber 1 inside the cryogenic storage compartment. Since the interior of the fresh food compartment 1 is limited and the suction device 3 occupies the interior of the fresh food compartment 1 when located inside the fresh food compartment 1, it is preferable that the suction device 3 be located inside the compressor compartment or in an area outside the fresh food compartment 1 within the low-temperature storage compartment. When the suction device 3 is positioned in the compressor bin, the space for installing the suction device 3 is not required to be additionally arranged, the structure of the refrigerator is more compact, and when the suction device 3 is positioned in the area outside the fresh-keeping chamber 1 in the low-temperature storage chamber, the internal space of the fresh-keeping chamber 1 is not occupied.

The modified atmosphere film 2 is a nitrogen-rich film made of a high molecular organic material, and the surface of the modified atmosphere film 2 is provided with a high molecular group which is close to nitrogen, so that when the pressure difference is generated on the two sides of the modified atmosphere film 2, the nitrogen is easily coated on the film and passes through, namely when the suction device 3 sucks air, the pressure in the modified atmosphere space 4 is lower than the pressure outside the fresh-keeping chamber 1, and at the moment, the nitrogen in the air outside the fresh-keeping chamber 1 penetrates through the modified atmosphere film 2 and enters the modified atmosphere space 4, and most oxygen in the air is blocked.

The thicker the modified atmosphere film 2, the lower the oxygen permeability, the higher the nitrogen purity in the modified atmosphere preservation space 4, but the smaller the nitrogen permeability, the longer the pumping time of the pumping device 3, the higher the cost, and the poorer the user experience, therefore, the thickness of the modified atmosphere film 2 can be 0.8-1.5 mm, preferably 1mm, the modified atmosphere film 2 in this thickness range can ensure that the oxygen permeability is not too high, and can also ensure that the nitrogen permeability is not too low, the pumping time of the pumping device 3 is also short, and the cost performance is highest.

The mounting frame 7 and the fresh-keeping chamber 1 can be connected in various ways, for example, the mounting frame 7 can be directly bonded to the upper surface of the fresh-keeping chamber 1; for another example, referring to fig. 2, the outer wall of the mounting frame can be hermetically connected with the inner wall of the air inlet 5, that is, the external dimension of the mounting frame 7 can be adapted to the dimension of the inner hole of the air inlet 5, and the mounting frame 7 can extend into the air inlet 5 and be hermetically connected with the hole wall of the air inlet 5, because the mounting frame 7 is directly bonded on the upper surface of the fresh-keeping chamber 1, the mounting frame 7 and the air-conditioning film 2 are higher than the upper surface of the fresh-keeping chamber 1, and the overall height of the fresh-keeping chamber 1 is increased; the mounting frame 7 extends into the air inlet 5 and is in sealing connection with the hole wall of the air inlet 5, only the air-conditioning film 2 is higher than the fresh-keeping chamber 1, and the height increase of the fresh-keeping chamber 1 can be ignored due to the fact that the air-conditioning film 2 is thin and is made of soft materials, and therefore the outer wall of the mounting frame 7 is preferably in sealing connection with the inner wall of the air inlet 5.

Referring to fig. 5, the modified atmosphere membrane 2 may be rectangular or circular or other shapes, and the shape of the mounting frame 7 is not limited herein, and the mounting frame 7 may be related to the shape of the modified atmosphere membrane 2, for example, when the modified atmosphere membrane 2 is rectangular, the mounting frame 7 may be a rectangular frame structure, when the modified atmosphere membrane 2 is circular, the mounting frame 7 may be a hollow cylinder structure, and the radial dimension of the modified atmosphere membrane 2 may be larger than that of the mounting frame 7 for better appearance and installation convenience.

The air inlet 5 can be arranged at a plurality of positions, for example, the air inlet 5 can be arranged on the side surface of the fresh-keeping chamber 1; as shown in fig. 3 and 7, the air inlet 5 may also be disposed at the center of the top of the fresh food compartment 1, and as shown in fig. 1, one or two side surfaces of the fresh food compartment 1 may sometimes be attached to or have a short distance from the refrigerator liner 20, a gap is generally formed between the top surface of the fresh food compartment 1 and the refrigerator liner 20, the area of the top surface of the fresh food compartment 1 is generally large, and when the air inlet 5 is disposed at the side surface of the fresh food compartment 1, the size of the air inlet 5 may be limited, which may cause the suction device 3 to operate for a long time, and the air inlet 5 may be blocked by the refrigerator liner 20, which may cause the air to flow unsmoothl; when air inlet 5 was seted up at the top center of freshfood compartment 1, the size range of air inlet 5 was bigger, and suction device 3 operating time is shorter, and air inlet 5 is difficult to be sheltered from, and the circulation of air is more smooth and easy, consequently, the preferred air inlet 5 is seted up at the top center of freshfood compartment 1.

There are various realizable ways of the suction device 3, and the suction device 3 may be a fan, for example; as another example, referring to fig. 2, the suction device 3 may also be an air pump, because the blower is generally large in volume and loud in noise; the suction pump is small in size and low in noise, so that the suction device 3 is preferably a suction pump, a suction port of the suction pump is connected to the air outlet 6 through an air pipeline 22, and an exhaust port of the suction pump is communicated with the outside of the refrigerator.

Referring to fig. 3 and 4, in order to conveniently take and place food materials, the fresh food compartment 1 may include a compartment body, a sealing member 9 and a drawer 8, the compartment body forms two sidewalls, a top wall, a bottom wall and a rear wall of the fresh food compartment 1 and defines a front inlet 16, an outer side of the front inlet 16 forms a peripheral member 17 surrounding the front inlet 16, a mouth portion of the peripheral member 17 is provided with a sealing groove, the sealing member 9 is located in the sealing groove, the drawer 8 forms a storage space, the drawer 8 is capable of moving in a specific direction from the inner side of the compartment body, the drawer 8 includes a drawer front plate 15, the drawer front plate 15 may compress the sealing member 9 when the drawer 8 is closed, the drawer 8 and the compartment body are locked by a locking device, the locking device may be a snap lock including a snap and a locking tongue which are engaged with each other, the snap is disposed on the compartment body, the locking tongue is, the locking and unlocking between the drawer 8 and the box body are realized. Therefore, when the suction device 3 sucks gas in the fresh-keeping chamber 1, the air outside the fresh-keeping chamber 1 can only enter from the fresh-keeping chamber air inlet 5 and cannot enter from the gap between the drawer 8 and the fresh-keeping chamber 1, and the time for the controlled atmosphere fresh-keeping space 4 to reach the required oxygen concentration value is shortened, so that the operation time of the suction device 3 is shortened, the resources are saved, and the cost is reduced.

The box generally is the plastics material, needs injection moulding, and when the box was the integral part, the drawing of patterns degree of difficulty was great, as shown in fig. 3, the box can be for the part of piecing, including epitheca 18 and inferior valve 19, can adopt to melt between epitheca 18 and the inferior valve 19 and bond and also can be through setting up the sealing member between the two and connect.
