As shown in fig. 1 and referring to fig. 2 to 7, an embodiment of the present invention provides a refrigerator. The refrigerator may include a cabinet 50, a first drawer 10, a modified atmosphere preservation apparatus 20, and a refrigeration system. The box body 50 is provided with a storage compartment, and the storage compartment comprises a refrigerating compartment 51, a freezing compartment 52 and a temperature-changing compartment 53. The storage temperature of the refrigerated compartment 51 is generally between 2 ℃ and 10 ℃, preferably between 3 ℃ and 8 ℃. The temperature in the freezer compartment 52 typically ranges from-14 ℃ to-22 ℃. The temperature-changing compartment 53 can be adjusted as needed to store suitable food, optionally, the temperature-changing compartment 53 has a temperature range of-24 ℃ to 10 ℃.

The refrigerating system is configured to provide cold energy to the storage compartment, and can be a refrigerating cycle system composed of a compressor, a condenser, a throttling device, an evaporator and the like.

As shown in fig. 3-7, the modified atmosphere preservation apparatus 20 can comprise a barrel 21, a second drawer 22, and a modified atmosphere module. A drawer space is defined in the cylinder 21. The second drawer 22 is slidably mounted to the barrel 21 for operable withdrawal outwardly from the forward opening of the barrel 21 and insertion inwardly into the barrel 21. The modified atmosphere module is mounted on the barrel 21 and has at least one modified atmosphere membrane and an oxygen-enriched gas collection chamber, the oxygen-enriched gas collection chamber is communicated with the air extracting device such as a vacuum pump, so that the modified atmosphere module is configured to make oxygen in the drawer space penetrate more through the modified atmosphere membrane into the oxygen-enriched gas collection chamber than nitrogen in the drawer space.

As shown in fig. 1 and 2, the first drawer 10 and the air-conditioning fresh-keeping device 20 are alternatively and detachably disposed in the storage compartment. That is to say, the first drawer 10 and the modified atmosphere preservation device 20 are both detachably installed in the storage compartment, and when in use, a user can alternatively install the first drawer 10 or the modified atmosphere preservation device 20 in the storage compartment according to the use requirement for use. Alternatively, the user may select the first drawer 10 or the modified atmosphere device 20 as an accessory for purchase at the time of purchase. When the user purchases the first drawer 10 and the air-conditioning fresh-keeping device 20, the user can use the first drawer alternatively.

The refrigerator provided by the embodiment of the invention has the air-conditioning membrane component, so that a nitrogen-rich and oxygen-poor gas atmosphere which is beneficial to food preservation can be formed in the drawer space, the oxygen content of the fruit and vegetable preservation space is reduced by the gas atmosphere, the aerobic respiration intensity of the fruit and vegetable is reduced, the basic respiration is ensured, the anaerobic respiration of the fruit and vegetable is prevented, and the purpose of long-term preservation of the fruit and vegetable is achieved. And the traditional drawer and the air-conditioning fresh-keeping device 20 can be exchanged according to the requirement so as to meet the diversified use requirements.

In some embodiments of the present invention, as shown in fig. 3 and 4, a communication port is provided on the cylinder 21. The modified atmosphere preservation device 20 also comprises a moisture permeable device 24. The moisture permeable device 24 can be installed at the communication port, and the moisture permeable device 24 has a moisture permeable film to make moisture flow in one direction, and when the humidity in the drawer space is greater than the humidity outside the cylinder 21, the moisture in the drawer space flows out of the drawer space through the moisture permeable film. And the moisture permeable film can lead the water in the second drawer 22 to be distributed, thereby preventing the interior of the drawer space from frosting in the process of refrigeration and after the refrigeration is finished. The storage compartment is preferably a temperature-changing compartment 53. The second drawer 22 of the refrigerator of the present invention is particularly useful for short-term storage of meat products.

Further, the refrigerator can also comprise an air extraction device which can be communicated with the oxygen-enriched gas collection cavity of the modified atmosphere membrane module through a pipeline so as to exhaust oxygen in the drawer space. The air extractor can be a vacuum pump and pumps the gas penetrating into the oxygen-enriched gas collecting cavity out of the storage container. The air extractor extracts air outwards, so that the pressure of the oxygen-enriched air collecting cavity is smaller than the pressure of the surrounding space of the modified atmosphere membrane component, and further, oxygen in the surrounding space of the modified atmosphere membrane component can enter the oxygen-enriched air collecting cavity. Because the drawer space is communicated with the space around the gas regulating membrane component, the air in the drawer space can enter the space around the gas regulating membrane component, so that the oxygen in the air in the drawer space can also enter the oxygen-enriched gas collecting cavity, and the gas atmosphere which is rich in nitrogen and poor in oxygen and is beneficial to food preservation is obtained in the drawer space. The air extractor can be installed on the box body 50, and particularly can be located at the rear part of the storage chamber, after the air-conditioning and fresh-keeping device 20 is installed in the storage chamber, the pipeline of the oxygen-enriched gas collecting cavity is communicated with the inlet of the air extractor. In some embodiments, the air extractor can be mounted directly to the bowl 21 to form an integral part with the modified atmosphere device 20.
