As shown in figure 39, when if the access main power source begins the operation (step S1) of refrigerator, then first stipulated time (time A) and second stipulated time (time B) are carried out zero clearing (step S2), will be used to judge that the pressure value P of the pressure of low-pressure chamber 24 is set at 1.0 (atmospheric pressure) (step S3).
Here, time A is used to the stand-by time of judging that low-pressure chamber 24 is operated at the appointed time.
It is if then connect less than 0.8 air pressure that pressure switch 84 is used according to its characteristic, if the switch that then disconnects more than 0.8 air pressure.Therefore, time B is set at from pressure switch 84 and reaches more than 0.8 air pressure that the back disconnects beginning until wait near till reaching the atmospheric pressure time because of gas leakage.
Judge that pressure value P is 1.0 or 0.7 (step S4).Here, pressure value P is 0.7 to be meant that low-pressure chamber 24 is depressurized to the pressure of the occasion till the authorized pressure.
In step S4, judging that pressure value P is 1.0 occasion, transfer to the reduce pressure processing of occasion of action of low-pressure chamber 24 for atmospheric pressure in the imaginary low-pressure chamber 24.
In the processing that is used for carrying out this decompression action, at first, judge the open and-shut mode (step S11) of low-pressure chamber doors 50 by low-pressure chamber door switch 83.In this step S11, judging that low-pressure chamber door 50 is in the occasion of open mode, owing to there is no need to carry out the decompression action of low-pressure chamber 24, therefore, time A is carried out zero clearing (step S12), and return the judgement that step S11 proceeds the open and-shut mode of low-pressure chamber door 50, wait for that low-pressure chamber door 50 is in closed condition.Here, time A is the stand-by time that is used to judge that low-pressure chamber 24 is to a certain extent operated.
In step S11, judging that low-pressure chamber door 50 is in the occasion of closed condition, then waits by the time elapsed time A (step S13).The purpose that makes low-pressure chamber 24 be in decompression state is freshness and the long preservation in order to keep food after all, thereby repeat to open and close the occasion of low-pressure chamber door 50 within a short period of time in order to prepare to have a meal for example user, the action of just needn't at every turn reducing pressure, in addition, keeping more longways the service life of vavuum pump 29, the time A of setting also is effective for fear of frequent action.
And, in the occasion of having passed through time A, judge the open and-shut mode (step S14) of low-pressure chamber door 50 by low-pressure chamber door switch 83.In this step S14, judging that low-pressure chamber door 50 is in the occasion of open mode, owing to there is no need to carry out the decompression action of low-pressure chamber 24, therefore, return step S12, wait for that low-pressure chamber door 50 is in closed condition.
