When the inflow of blow out air A stops, the temperature of the air in the 1st accommodating container 6b rises.That is, the temperature of the air in the 1st accommodating container 6b changes repeatedly.Therefore, the 1st temperature of preserving food group 16 also changes repeatedly.
To this, the 2nd accommodating container 6c becomes roughly air-tight state.Therefore, blow out air A does not flow into the 2nd accommodating container 6c.In this case, the 2nd accommodating container 6c, across interface wall 9, is indirectly cooled.That is, the temperature of the 2nd accommodating container 6c is because the cold emission from switching chamber 4 declines.
Even if the inflow of blow out air A stops, from the cold emission of switching chamber 4, being also maintained.That is, the temperature change of the air in the 2nd accommodating container 6c is little.Therefore, the 2nd preservation food group's 17 temperature change is also little.

In Fig. 3, Reference numeral 18 is temperature history measured values of the air in not divided zero degree chamber 6.Reference numeral 19 is temperature history analytic value of the air in the 1st accommodating container 6b.Reference numeral 20 is temperature history analytic value of the air in the 2nd accommodating container 6c.In addition, the temperature of switching chamber 4 is set to cryogenic temperature band (18 ℃).
As shown in Figure 3, temperature history analytic value 19 is rendered into roughly consistent with temperature history measured value 18.That is,, in the 1st accommodating container 6b, the cycle of temperature history analytic value 19 is approximately 110 minutes.In the 2nd accommodating container 6c, the cycle of the temperature history analytic value 20 of air is approximately also 110 minutes.
In the 1st accommodating container 6b, the mean value of temperature history analytic value 19 is approximately 0.8 ℃.With respect to this, in the 2nd accommodating container 6c, the mean value of temperature history analytic value 20 is approximately-0.9 ℃.That is, the mean temperature of the air in the 2nd accommodating container 6c is lower than the mean temperature of the air in the 1st accommodating container 6b.
In the 1st accommodating container 6b, the amplitude of fluctuation of temperature history analytic value 19 is approximately 3.6 ℃.With respect to this, in the 2nd accommodating container 6c, the amplitude of fluctuation of temperature history analytic value 20 is approximately 2.7 ℃.That is, the temperature change amplitude of the air in temperature change Amplitude Ratio the 1st accommodating container 6b of the air in the 2nd accommodating container 6c is little.
The temperature of the air of the 2nd accommodating container 6c then, is described with Fig. 4.
Fig. 4 is for the figure of temperature of air of the 2nd accommodating container of the refrigerator of embodiment 1 of the present utility model is described.The transverse axis of Fig. 4 is the wall thickness (mm) of the bottom surface of the 2nd accommodating container 6c.The longitudinal axis of Fig. 4 be mean temperature (℃) and temperature change amplitude (℃).
In Fig. 4, Reference numeral 21a is the mean temperature analytic value of the air in the 2nd accommodating container 6c that formed by plastics of bottom surface.Reference numeral 21b is the mean temperature analytic value of the air in the 2nd accommodating container 6c that formed by aluminium of bottom surface.Reference numeral 22a is the temperature change amplitude analytic value of the air in the 2nd accommodating container 6c that formed by plastics of bottom surface.Reference numeral 22b is the temperature change amplitude analytic value of the air in the 2nd accommodating container 6c that formed by aluminium of bottom surface.
As shown in Figure 4, even if the either party of the bottom surface of the 2nd accommodating container 6c in plastics, aluminium forms, with respect to the variation of the wall thickness of this bottom surface, mean temperature analytic value 21a, 21b, temperature change amplitude analytic value 22a, 22b also change hardly.
Mean temperature analytic value 21b is less than mean temperature analytic value 21a.That is,, in the situation that the material of the bottom surface of the 2nd accommodating container 6c is altered to aluminium from plastics, the mean temperature in the 2nd accommodating container 6c declines.
Temperature change amplitude analytic value 22b is less than temperature change amplitude analytic value 22a.That is,, in the situation that the material of the bottom surface of the 2nd accommodating container 6c is altered to aluminium from plastics, the temperature change amplitude of the air in the 2nd accommodating container 6c reduces.
Adjacent with switching chamber 4 according to embodiment 1, the 2 accommodating container 6c described above.Now, the temperature of the 2nd accommodating container 6c is because the cold emission from switching chamber 4 declines.Therefore, can seek the low temperature of the 2nd accommodating container 6c.
In addition, the peristome of the 2nd accommodating container 6c is inaccessible by the bottom surface of the 1st accommodating container 6b.Therefore, blow out air A does not flow into the 2nd accommodating container 6c.Its result, can seek the constant temperature of the 2nd accommodating container 6c.
In addition,, with respect to the 2nd accommodating container 6c, do not need the drive unit of air door and motor etc.Therefore, can make at an easy rate refrigerator 1.
By low temperature and the constant temperature of the 2nd accommodating container 6c, the 2nd preserves the environment that food group 17 is stored in low temperature.In this case, the 2nd, preserve between food group 17 and surrounding air, the difference of vapour pressure is little.Therefore, can improve the 2nd preservation food group's 17 preservation quality.That is, moisture (drop) be can suppress and food group 17 oxidation and variation from the 2nd outflow, the 2nd of preserving food group 17, preserved.
For example, even if be near 0 ℃ of zero degree temperature band by the Temperature Setting of the 1st accommodating container 6b, the temperature that the 2nd in the 2nd accommodating container 6c preserves food group 17 can be not repeatedly reduce below to the apparent freezing point of-2 ℃ of left and right yet.Therefore, the 2nd preservation food group 17 is not frozen.Now, the 2nd temperature of preserving food group 17 is not in the scope of the maximum ice crystallization generating zone of-5 ℃～-1 ℃.Therefore, the 2nd, preserve in food group 17, ice crystal is not grown up.Therefore, the 2nd, preserve in food group 17, the destruction of cell is suppressed.Therefore, can suppress drop produces in large quantities.
In addition, in the cooling middle utilization of the 2nd accommodating container 6c, switching chamber 4 cooling become to the superfluous heat of cooling.Therefore, do not need the cooling capacity for cooling the 2nd accommodating container 6c.Its result, can suppress the consumed energy of refrigerator 1 integral body.
In addition, processed food and fresh food are classified preservation.That is, can food be preserved under the state arranging according to kind.In this case, can prevent that the smell of raw meat, raw fish is to other food transfer.
