Content, including oxygen content, it is also possible to including nitrogen content, carbon dioxide content etc..
The control process of air pump 40 can be：Collection first gas detection means 281 and second gas detection means 282
The oxygen concentration of detection, fresh-keeping subspace 271 oxygen concentration beyond default fresh-keeping scope or keep-alive subspace 272
When oxygen concentration is less than default keep-alive scope, air pump 40 starts, and the oxygen of fresh-keeping subspace 271 is arranged to keep-alive subspace
272.And maintain the oxygen concentration of fresh-keeping scope or keep-alive subspace 272 in the oxygen concentration in fresh-keeping subspace 271
Beyond default keep-alive scope when, air pump 40 is closed.
Meet fresh-keeping requirement in view of the oxygen concentration for being possible to occur fresh-keeping subspace 271, and keep-alive subspace
272 oxygen concentration does not also meet the situation of keep-alive requirement, or the oxygen concentration of keep-alive subspace 272 has met keep-alive and wanted
Situation about asking, but the oxygen concentration of fresh-keeping subspace 271 is situations such as cannot also meet fresh-keeping requirement.First closed component 71
(such as on the barrel of the first drawer cylinder) is also provided with the 4th intercommunicating pore 291 of controlled opening and closing, so that fresh-keeping subspace 271 is controlled
Ground is connected with storage space.On the barrel of first closed component 71 (such as on the barrel of the second drawer cylinder) the second drawer cylinder
The 5th intercommunicating pore 292 of controlled opening and closing can also be provided with, so that keep-alive subspace 272 controllably connects with storage space.
Oxygen concentration in fresh-keeping subspace 271 has met fresh-keeping requirement, and the oxygen concentration of keep-alive subspace 272 is also
The situation of keep-alive requirement is not met, because now air pump 40 possibly cannot continue to extract enough out from fresh-keeping subspace 271
Oxygen provide to keep-alive subspace 272, now, the 4th intercommunicating pore 291 is opened, with allow storing air gas enter it is fresh-keeping
Subspace 271, so that oxygen-enriched membrane component 30 prepares more oxygen.Under general state, the 4th intercommunicating pore 291 is remained turned-off.
Oxygen concentration in keep-alive subspace 272 has met fresh-keeping requirement, and the oxygen concentration of fresh-keeping subspace 271 is also
Do not meet the situation of fresh-keeping requirement, due to the oxygen that now air pump 40 is extracted out from fresh-keeping subspace 271 cannot continue to
Keep-alive subspace 272 provides, and now, the 5th intercommunicating pore 292 can be opened, to allow partial oxidation to enter storage space.One
As under state, the 5th intercommunicating pore 292 is remained turned-off.
In addition, above-mentioned rich nitrogen oxygen deprivation be beneficial in the atmosphere of food fresh-keeping specific oxygen concentration range can basis
The food species placed in fresh-keeping subspace 271 are determined.By the research to food fresh-keeping characteristic, inventor has found oxygen
Closely related with the Oxidation of fruit and vegerable, Repiration, not oxygen concentration is lower, is more conducive to the fresh-keeping preservation of fruit and vegerable,
Too low oxygen content also results in the situation that anaerobic respiration occurs in food, also results in food spoilage.Therefore every kind of fruit and vegerable can
Can there is optimal oxygen concentration range, therefore after user places fruit and vegerable in fresh-keeping subspace 271, fruit and vegerable type can be set
Or fruit and vegerable type is automatically identified by fridge-freezer, so as to the oxygen maintained to should determine that fresh-keeping subspace 271 to need
Concentration range.
The refrigerating device of the present embodiment, creatively proposes closed fresh-keeping subspace using oxygen-enriched membrane component
Oxygen in 271 in air is arranged to keep-alive subspace 272, so as to the oxygen deprivation of rich nitrogen is obtained in the fresh-keeping subspace 271 beneficial to food
The fresh-keeping atmosphere of thing.The atmosphere of rich nitrogen oxygen deprivation reduces fruit and vegerable by the content of oxygen in reduction fruit and vegerable shelf space
The intensity of aerobic respiration, while ensureing the Repiration on basis, prevents fruit and vegerable from carrying out anaerobic respiration, protects for a long time so as to reach fruit and vegerable
Fresh purpose.Meanwhile, the oxygen that oxygen-enriched membrane component 30 is separated out feeds to closed keep-alive subspace 272, makes keep-alive subspace 272
Oxygen concentration reaches can maintain more than the 70% of aquatic products long-term surviving.Therefore oxygen-enriched membrane component 30 can be simultaneously fruit and vegerable guarantor
Fresh fresh-keeping subspace 271 and realize that the keep-alive subspace 272 of fresh aquatic product keep-alive provides atmosphere, so as to enrich
The food fresh-keeping demand of user.
Further, refrigerating device of the invention, can also be by air pump 40, gas exhaust piping 52 and pumping
The working condition of pipeline 51 is adjusted, to maintain the atmosphere of fresh-keeping subspace 271 and keep-alive subspace 272.
