Shown in figure 39, after the refrigerator entry into service (step S1), remove first stipulated time (time A) and second stipulated time (time B) (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 judge the not operated at the appointed time stand-by time of low-pressure chamber 24, and time B is to the stand-by time of entry into service vavuum pump 29 after the closing presure switch 84.

Judge that pressure value P is 1.0 still is 0.7 (step S4).Here, so-called pressure value P is 0.7 to mean the pressure when low-pressure chamber 24 is decompressed to authorized pressure.

In step S4, determining pressure value P is 1.0 o'clock, supposes to be atmospheric pressure in the low-pressure chamber 24 processing when immigration is reduced pressure action to low-pressure chamber 24.

In the processing that is used for this decompression action, at first judge the open and-shut mode (step S11) of low-pressure chamber door 50 through low-pressure chamber door switch 83.When in this step S11, determining low-pressure chamber door 50 for open mode; Owing to need not get into the decompression action of low-pressure chamber 24; So checkout time A (step S12) returns the open and-shut mode that step S11 continues to judge low-pressure chamber door 50, wait for that low-pressure chamber door 50 becomes closed condition.Here, time A is used to judge the not operated stand-by time of low-pressure chamber 24 to a certain degree.

When in this step S11, determining low-pressure chamber door 50, wait for to elapsed time A (step S13) for closed condition.The purpose that makes low-pressure chamber 24 become decompression state at first is food fresh keeping and long preservation; The for example the sort of situation action of need not reducing pressure when the user opens and closes low-pressure chamber door 50 at short notice repeatedly in order to prepare food keeps the life-span of vavuum pump 29 and the time of setting A is effective for fear of frequent operation in addition for a long time.

And, when elapsed time A, judge the open and-shut mode (step S14) of low-pressure chamber door 50 through low-pressure chamber door switch 83.When in this step S14, determining low-pressure chamber door 50,,, wait for that low-pressure chamber door 50 becomes closed condition so return step S12 owing to need not get into the decompression action of low-pressure chamber 24 for open mode.

When in step S14, determining low-pressure chamber door 50, judge the open and-shut mode (step S15) of refrigerating-chamber door 6 through refrigerating-chamber door switch 82 for closed condition.When in this step S15, determining refrigerating-chamber door 6 for open mode, vavuum pump 29 shuts down (step S16), returns step S14.

When in step S15, determining refrigerating-chamber door 6, judge that through refrigerator temperature sensor 85 temperature of refrigerating chamber 2 is high temperature (for example more than 8 ℃) or low temperature (for example less than is 8 ℃) (step S17) for closed condition.When the temperature that in this step S17, determines refrigerating chamber 2 is high temperature, return step S16.That is be, owing to when the temperature of refrigerating chamber 2 is high temperature, can not begin the decompression action that vavuum pump 29 is carried out.

When the temperature that in step S17, determines refrigerating chamber 2 is low temperature, vavuum pump 29 turn round (step S19).Like this, detect each state of low-pressure chamber door 50, refrigerating-chamber door 6 and refrigerating chamber 2 before vavuum pump 29 entrys into service,, therefore, can be only limited to that vavuum pump 29 turns round in the time of need reducing pressure to low-pressure chamber 24 based on these vavuum pump 29 entrys into service as a result.

In step S18, after vavuum pump 29 entrys into service, determine the still not enough pressure of stipulating (for example 0.8 atmospheric pressure of less than) (step S19) of the pressure that pressure in the low-pressure chamber 24 are regulations (for example 0.8 more than the atmospheric pressure) through pressure switch 84.Pressure (1.0 atmospheric pressure (atmospheric pressure)) on the pressure of this regulation (0.8 atmospheric pressure) is used to judge with pressure value P and under pressure (0.7 atmospheric pressure) between pressure, be near under the pressure of pressure.

In this step S19, determine pressure in the low-pressure chamber 24 and be 0.8 atmospheric pressure when above, remove the integrated value (step S20) of the duration of runs (time d) of vavuum pump 29, return step S14, vavuum pump 29 remains in operation.

In step S19, determine pressure in the low-pressure chamber 24 when being 0.8 atmospheric pressure of less than, vavuum pump 29 remains in operation, to duration of runs of vavuum pump 29 be that time d carries out integration and stores its integrated value (step S21).Then, the integrated value of judgement time d is more than the 3rd stipulated time (time D) or not enough time D (step S22).When the integrated value that in this step S22, determines time d is not enough time D, return step S14, keep watch on each state of low-pressure chamber door 50, refrigerating-chamber door 6 and refrigerating chamber 2, and vavuum pump 29 remains in operation.

The integrated value that in this step S22, determines time d is time D when above, and vavuum pump 29 shuts down (step S23), and pressure value P is set at 0.7 atmospheric pressure and returns step S4.

When in step S4, determining pressure value P and being 0.7 atmospheric pressure, judge the open and-shut mode (step S31) of low-pressure chamber doors 50 through low-pressure chamber door switch 83.When in this step S31, determining low-pressure chamber door 50, get into step S35 for open mode.

When in step S31, determining low-pressure chamber door 50, determine the still not enough pressure of stipulating (for example 0.8 atmospheric pressure of less than) (step S32) of the pressure that pressure in the low-pressure chamber 24 are regulations (for example 0.8 more than the atmospheric pressure) through pressure switch 84 for closed condition.In this step S32, determine pressure in the low-pressure chamber 24 when being 0.8 atmospheric pressure of less than, checkout time B (step S33) returns step S31.

In step S32, determine pressure in the low-pressure chamber 24 and be 0.8 atmospheric pressure when above, determine and whether passed through time B (step S34).When in this step S34, determining not elapsed time B, return step S31.

In step S34, determine when having passed through time B, checkout time B (step S35) pressure value P being set at 1.0 backs (step S36), returns step S4.
