It can be controlled by controlling the start-stop time of controlled-atmosphere preservation system 80, the control without carrying out oxygen concentration.
Alarm reminder 86 can be used the modes such as display, acousto-optic, remote alarms and carry out information alert to user.
Controller 110, the control core of the refrigerating device as the present embodiment can pass through various microprocessors
(including single-chip microcontroller, digital signal processor etc.) and its accessory circuit (power supply, memory, clock circuit) are corresponding by configuring
Program is controlled to realize.In order to guarantee the co-ordination of refrigeration system 70 and controlled-atmosphere preservation system 80, in the refrigeration of the present embodiment
In refrigerating plant, controller 110 can determine whether that controlled-atmosphere preservation system 80 starts by the way that fresh-keeping operation mark is arranged
Work.
Fresh-keeping operation mark can be marker in a certain register of controller 110, include at least two states: respectively
Indicating allows controlled-atmosphere preservation system 80 to run and controlled-atmosphere preservation system 80 is forbidden to run.When carrying out controlled atmosphere control, control
Device 110 processed can obtain the fresh-keeping operation mark of controlled-atmosphere preservation system 80 first.Fresh-keeping operation mark is according to refrigerating device
Run case be configured, and indicate whether allow controlled-atmosphere preservation system 80 run.The operation thing of refrigerating device
Part includes at least: event that the time of running of refrigerating device, the start and stop event of refrigeration system 70, storage space are opened and closed,
The event that controlled atmosphere subspace 271 is opened and closed.
Various sensors that the run case of above-mentioned refrigerating device can be arranged by refrigerating device, detection dress
It sets and control instruction that controller 110 issues is determined.Such as the time of running of refrigerating device can use refrigeration
The clock of refrigerating plant determines that the start and stop event of refrigeration system 70 can be by detecting the state of compressor or passing through controller
110 events being opened and closed to the control instruction determination of the transmission of refrigeration system 70, storage space can be opened and closed by refrigerating chamber to be detected
Device 72 can be opened and closed detection dress come the event detected, controlled atmosphere subspace 271 is opened and closed by controlled atmosphere subspace
82 are set to be detected.
In the case where fresh-keeping operation, which is identified as, allows controlled-atmosphere preservation system 80 to run, controller 110 may determine that controlled atmosphere
Whether fresh-keeping system 80 meets default compressor start up condition, and in the case where meeting compressor start up condition, start controlled-atmosphere preservation system 80 with
The gas of controlled atmosphere subspace 271 is adjusted, until controlled-atmosphere preservation system 80 reaches preset cut-off condition.
Controller 110 be arranged it is above-mentioned it is fresh-keeping operation mark process may include: in the initial state, can be by above-mentioned guarantor
Fresh operation mark is set as illegal state.In addition after the starting of refrigeration system 70, illegal state is set by fresh-keeping operation mark,
And after pent first preset time of refrigeration system 70, fresh-keeping operation mark is positioned to allow for state.It is refrigerated entering
After the frequent enabling period of refrigerating plant, illegal state is set by fresh-keeping operation mark, and waiting the period of frequently opening the door
Through later, fresh-keeping operation mark being positioned to allow for state.After storage space is opened, fresh-keeping operation mark is set as prohibiting
Only state, and after pent second preset time of storage space and controlled atmosphere subspace 271 is continuously off reaches
In the case where third preset time, fresh-keeping operation mark is positioned to allow for state.
With the above arrangement, can start in a case where to avoid controlled-atmosphere preservation system 80: simultaneously with refrigeration system 70
Starting is often picked and placed in the period of thing in starting state, in user, is started in the case where user opens storage room.
Above-mentioned first preset time, the second preset time, third preset time can according to the operating condition of refrigerating device and
Specification is configured.Such as first preset time can be closed according to refrigeration system 70 after compressor shut down and radiate and reach
Time to a certain extent is determined, thus avoid aspiration pump 40 be superimposed with the heat of compressor and noise superposition.Second is pre-
If after the time can be according to the shutdown of storage room, the time that refrigeration system 70 is restored to operate normally is configured.Third is default
Time can be configured according to the gas leakage situation of controlled atmosphere subspace 271, such as can determine controlled atmosphere according to testing
In the case where not being turned on, the atmosphere of rich nitrogen oxygen deprivation is unable to satisfy the time of antistaling storing requirement for fresh-keeping subspace 271
It is configured.
The frequent enabling period of refrigerating device can summarize according to the use habit of user to obtain, such as with day
It is more than the period of pre-determined number as the above-mentioned frequent enabling period using number of opening middle daily for the period.In addition it is another can
It selects in embodiment, can also be summarized as unit of week.It is avoided as far as possible in user through normally open refrigerating device door body
Period starts controlled-atmosphere preservation system 80.
In the case that fresh-keeping operation mark is positioned to allow for state, controller 110 can be according to controlled atmosphere subspace 271
And the operating condition of controlled-atmosphere preservation system 80 boots up the judgement of condition.
In the case where oxygen concentration sensor 84 are arranged, it can be booted up according to oxygen concentration and be sentenced with cut-off condition
It is disconnected.The oxygen concentration range of the best storage ambient of different types of food may be different, in some optional embodiments, can be with
It is determined by the corresponding oxygen concentration range of multiclass food items in advance, and passes through use in controlled atmosphere subspace 271
Family input or automatic identification mode determine the information of food, determine corresponding oxygen concentration range.To compressor start up condition
The preset oxygen concentration upper limit can be greater than or equal to for the oxygen concentration of controlled atmosphere subspace 271, that is, protected in controlled atmosphere
In the case that the oxygen concentration of fresh subspace 271 is greater than or equal to the oxygen concentration upper limit, need to start aspiration pump 40 and blower 60.
Cut-off condition can be less than or equal to preset oxygen concentration lower limit for the oxygen concentration of controlled atmosphere subspace 271, that is,
In the case where the oxygen concentration of controlled atmosphere subspace 271 is greater than or equal to the oxygen concentration upper limit, need to close aspiration pump 40
With blower 60, controlled atmosphere operation is completed.
Another optional switching on and shutting down condition can be that the pumping efficiency to aspiration pump 40 and controlled atmosphere are empty in advance
Between 271 gas leakage situation tested, determine aspiration pump 40 complete controlled atmosphere pumping time it is default as the 6th
Time, and the time that gas natural leak to oxygen concentration in controlled atmosphere subspace 271 is unable to satisfy fresh-keeping requirement is made
For the 5th preset time.To which compressor start up condition may include: to complete controlled atmosphere subspace apart from last time controlled-atmosphere preservation system 80
