Fig. 4 is that the expression temperature is switched the right flank sectional drawing of chamber 3.The top and bottom that temperature is switched chamber 3 are divided into refrigerating chamber 2 and vegetable compartment 5 by means of partition wall 7,8.The front that temperature is switched chamber 3 can be opened and closed by rotary door 9.The back side that temperature is switched chamber 3 is covered by backplate 33.Switch 3 the insides, chamber in temperature and dispose drawer type accommodation box 11.
The rear of plate 33 is provided with between the thermal wall 10 of this backplate 33 and formation outer wall and imports ventilation road 12 overleaf.Inflow entrance 33a and cold air path 31 (with reference to Fig. 3) that importing ventilation road 12 will be arranged on the backplate 33 link together.Import and be provided with temperature switching chamber discharge baffle plate 13 (importing side switching portion) in the ventilation road 12.Switch chamber discharge baffle plate 13 by opening temperature, will in evaporimeter 17, the cold air importing temperature of (with reference to Fig. 3) generation switch chamber 3.
(a)～(c) among Fig. 8 is front elevation, vertical view and the side sectional drawing of representing temperature switching chamber discharge baffle plate 13 respectively.Temperature is switched chamber discharge baffle plate 13 and be provided with deflection plate 42 in the housing 40 that is made of synthetic resin, and this housing 40 is provided with peristome 40a in front.Deflection plate 42 by be arranged on the upper end feathering axis 42a pivotal support in housing 40.
By the driving of the CD-ROM drive motor 41 that is connected with rotating shaft 42a, deflection plate 42 can rotate along mode shown in the arrow H.By means of the rotation of deflection plate 42,40a opens and closes to peristome, and temperature is switched chamber discharge baffle plate 13 and opened and closed.Deflection plate 42 in the face of on the surface of peristome 40a, be provided with the seal member 43 that heat-insulating material that the periphery with peristome 40a fits tightly constitutes.
Fig. 9 is that the expression temperature is switched the side sectional drawing that the installment state of baffle plate 13 is discharged in the chamber.Temperature is switched chamber discharge baffle plate 13 and is installed on the wall 50 that imports ventilation road 12.In addition, as hereinafter describing in detail, difference on the direction of the temperature switching chamber 3 that is configured in the left side in the drawings, importing ventilation road 12 and the direction of the shock chamber 23 that is configured in the top, right side among the figure is switched chamber 3 via the 50a of hole portion with temperature and is communicated with.In addition, temperature is switched chamber discharge baffle plate 13, switches chamber 3 one sides (left side among the figure) in temperature and disposes peristome 40a, disposes deflection plate 42 in evaporimeter 17 1 sides (right side among the figure).
Being lower than the indoor temperature that temperature is switched chamber 3, when closing peristome 40a, on deflection plate 42, produce temperature difference by deflection plate 42 through importing the cold air temperature that flows on ventilation road 12.As shown in figure 10, deflection plate 42 relative peristome 40a are configured in temperature when switching chamber 3 one sides (left side among the figure), deflection plate 42 except with inboard that peristome 40a is connected, all become high temperature.
Thereby when the high-temperature part of deflection plate 42 produced dewfall, when opening peristome 40a, because of the cold air of low temperature, dew froze, and 42a clings with rotating shaft.Therefore, when insufficient, produce the cooling deficiency that temperature is switched chamber 3, close when incomplete, produce the supercooling that temperature is switched chamber 3 by opening of 42 couples of peristome 40a of deflection plate.
Relative therewith, in the present embodiment, because deflection plate 42 relative peristome 40a are configured in evaporimeter 17 1 sides, so when closing peristome 40a, deflection plate 42 is that the inboard that is connected with peristome 40a becomes high temperature.Owing to be provided with the seal member of forming by heat-insulating material 43 on the surface of deflection plate 42, therefore, suppressed the generation of dewfall.Be preferably on the deflection plate 42, on the surface of an opposite side of facing peristome 40a one side, heat insulating member be set also.
Further,, also only produce, on the rotating shaft 42a of deflection plate 42, do not produce dewfall in the inboard that joins with peristome 40a even on deflection plate 42, produce dewfall.Thereby when opening peristome 40a, even dew freezes, deflection plate 42 also can regular event, can prevent that temperature from switching the cooling deficiency or the supercooling of chamber 3.
Particularly, as hereinafter describing in detail, switch chamber 3 in temperature and become under the situation of high temperature side (for example 55 ℃～80 ℃), the steam that is produced by reserve produces dewfall easily on deflection plate 42.Thereby even a large amount of dews freezes, deflection plate 42 also can run well, and has further improved the not enough or overcooled effect of cooling that prevents temperature switching chamber 3.Not only under the situation that deflection plate 42 rotates, even, also can obtain same effect in the situation of sliding and moving.
In addition, with other cooling chambers and cold air loop side by side in the storeroom of configuration, be provided with the baffle plate that is used to open and close the cold air path that cold air flows into, even closing baffle plate, make under the situation of the air circulation in the storeroom, also can obtain same effect by identical formation.That is to say, be configured in evaporimeter (cooling device) side, can prevent to take place because of the thing of the icing deflection plate cisco unity malfunction that causes of dew by peristome with the relative baffle plate of deflection plate.Therefore, can prevent the cooling deficiency or the supercooling of storeroom.
In addition, because rotating shaft 42a is configured in the upper end of deflection plate 42, therefore, even deflection plate 42 dewfall, dew also can be in a side of leaving rotating shaft 42a toward current downflow.Thereby, even dew freezes when having opened peristome 40a, also can further prevent freezing of rotating shaft 42a, can make deflection plate 42 normal rotation.
In addition, as shown in figure 11, when the pivot fulcrum of deflection plate 42 vertically was set, when peristome 40a opened fully, the dew that drips from deflection plate 42 repeated to pile up, and freezes, and hinders the rotation of deflection plate 42.As described in present embodiment, when rotating shaft 42a flatly was arranged on deflection plate 42 upper ends, when deflection plate 42 was opened fully at peristome 40a, the top was kept out of the way in its lower end.Therefore, even dew drips and freezes from deflection plate 42, also can prevent the obstacle that deflection plate 42 is rotated.
In above Fig. 9, the 50a of hole portion of wall 50 forms the step 50b that is lower than peristome 40a to form than peristome 40a hole enlargement ground.Therefore, when the dew of deflection plate 42 flows down,,, dew is imported temperature switch chamber 3 one sides by step 50b from the periphery of peristome 40a.Thereby, when opening deflection plate 42, can prevent that dew is from the intrusion of peristome 40a to evaporimeter 17 1 sides.Also can in the 50a of hole portion, form the inclined plane of extending from the periphery of peristome 40a.

As for the indoor temperature of high temperature side, because the developmental temperature of main food poisoning bacteria is 30 ℃～45 ℃, so, consider the tolerance of heater capacity or the Temperature Distribution in the temperature switching chamber 3 etc., preferably be set more than 50 ℃.Therefore, can prevent the breeding of germ.In addition, because the heat resisting temperature that is used for the general resin parts of refrigerator is 80 ℃, therefore, be set in below 80 ℃ the indoor temperature of high temperature side less expensive.
In addition, in order to eliminate the toadstool in the food, for example under the situation of intestinal bleeding Escherichia coli (pathogenicity Escherichia coli O 157), must under 75 ℃ of conditions, heat 1 minute.Thereby, consider that the tolerance of heater capacity or temperature switch the Temperature Distribution in the chamber 3 etc., the indoor temperature of high temperature side is set in 80 ℃ can be better.
Be the BA result of the food poisoning bacteria during about 55 ℃ below.Test specimen under the state, contains Escherichia coli 2.4 * 10 in the early stage
3CFU/mL, staphylococcus aureus 2.0 * 10
3CFU/mL, sramana's formula bacillus 2.1 * 10
3CFU/mL, enteritis vibrios 1.5 * 10
3CFU/mL and bacillus cercus 4.0 * 10
3CFU/mL.This test specimen was heated to 55 ℃ with 40 minutes from 3 ℃,, makes temperature turn back to 3 ℃ from 55 ℃, check the amount of each germ once more with 80 fens clock times 55 ℃ of insulations after 3.5 hours down.Consequently, any one bacterium all reduces to the level of lOCFU/mL following (detect less than).Thereby the high temperature side design temperature that temperature is switched chamber 3 is set at 55 ℃, also can obtain abundant sterilization effects.
