The cold air that has flowed into 0 passes through the first cooling duct 48, the third cooling duct 50, and the second cooling duct 49 and the outlet port 4.
4, respectively. The cold air distributed to the first cooling duct 48 blows out from the first outlet 45 to cool the first low temperature section 36. The cool air distributed to the second cooling duct 49 cools the lid body 38 of the second low temperature section 37 at the bottom surface of the second cooling duct 49, and blows out from the third outlet 46 and passes through the back surface of the second low temperature section 37. , The second low temperature section 37 is cooled and blown out to the third low temperature section 39. The third cooling duct 50 cools the cooling surface and acts so that the suction air 22 to the refrigerating compartment 6 does not directly reach the cool air. The cold air blown out from the second outlet 44 passes through the back surface of the second low temperature section 37, cools the third low temperature section 39, and then the third outlet 4
A little warm wind is sucked into the suction port 22 together with the cold air blown out from 6. Therefore, the first to third low temperature section 3

When 2 is at the rear, the third outlet 46 of the third cooling duct 50 may be at the front. In order to improve the temperature distribution, cold air outlets such as holes and slits may be provided in each part of the cooling duct.

Embodiment 3. Another embodiment according to the present invention will be described with reference to FIG. Reference numeral 42 denotes a moisture permeable material installed on the lid body 38, which is made of hydrophilic porous sintered resin and has a size substantially the same as that of the cooling duct 40, and is approximately 2/3 of the total area of the lid body 38. Is the size of. Next, the operation will be described. The second low temperature section 37 is indirectly cooled by the cooling duct 40 from the lid body 38, and is also cooled by the cool air blown from the second blowout port 44 and the third blowout port. The moisture permeable material 42 installed on the lid body 38 prevents dew condensation and frost formation on the lid body 38 and also adjusts the humidity, so that the temperature inside the second low-temperature section 37 can be controlled accurately at all times. Even if the food is stored without packaging or in simple packaging, the food is prevented from drying and can be stored with high quality. The aperture ratio of the moisture permeable material 42 can also be adjusted so that the humidity of the second low temperature section 37 can be adjusted. The aperture ratio of the moisture permeable material 42 is set so that dew condensation does not occur on the wall surface in the second low temperature section 37. For example, when the average air temperature (wall surface temperature) in the second low temperature section 37 is set to 0 ° C. and the average humidity is set to 90%, a moisture permeable material having an opening ratio of 60% is used.

Embodiment 4. Another embodiment according to the present invention will be described with reference to FIGS. 43 is the second
A guide plate, which is located on the rear surface of the low-temperature compartment 37 and has a shape that allows cool air to easily flow from above and is formed integrally with the lid body 5,
Reference numeral 2 is a cool air guide formed by extending the back wall of the third low temperature section 39 upward and rearward, projecting into the air passage, and opening upward. Next, the operation will be described. The guide plate 4 prevents the cool air blown from the second outlet 44 of the cooling duct 40 from contacting the back surface of the second low temperature section 37.
3 and flows efficiently along the cold air guide 52 on the back surface of the third low-temperature compartment 39 and circulates in the third low-temperature compartment 39 to cool the inside of the compartment. No direct dew or frost formation near the cool air passage on the back surface of the second low temperature section 37. After that, the cold air is sucked into the return port 22 provided at the bottom of the front surface of the refrigerating room 6 and enters the refrigerating room 6. The cold air guide 52 has the same function and effect even if it is locked to the back surface of the third low temperature compartment 39, or locked or integrally formed in the low temperature chamber 10.

Embodiment 5. Another invention according to the present invention will be described with reference to FIG. The minimum temperature of the moisture permeable material 42 is the ratio of the cross-sectional area of the second cooling duct 49 and the total of the areas of the first, second and third air outlets of the first embodiment, and the cool air flow rate in the second cooling duct 49. It is adjusted to, for example, −3 ° C. or higher depending on the operating time t ₁ and t _{2 of the} compressor 29. Breathable material 42
The maximum temperature of is kept at, for example, 2 ° C. or lower by a low temperature room damper thermostat 21 that senses and controls the temperature inside the low temperature room 10 by a temperature sensing part 21a installed in the low temperature room 10. When the damper thermostat 21 is controlled so that the average air temperature in the low greenhouse 10 becomes 0 ° C, the average temperature of the moisture permeable material 42 is -0.5 ° C.
Rank The average temperature of the moisture permeable material 42 is set to be slightly lower than the average air temperature in the low temperature chamber 10 in order to concentrate the condensation. For example, the temperature is set to be 0.5 ° C. lower, that is, the temperature of the moisture permeable material 42 is determined by the air temperature in the low temperature chamber 10. Further, the maximum and minimum temperatures occur due to hunting when the compressor 29 is turned on and off. Breathable material 4
By setting the temperature of 2 as described above, the frost formed on the moisture permeable material 42 during cooling reaches a temperature at which it is melted during non-cooling, and the moisture permeable material 42 absorbs water and evaporates. Since the moisture-permeable material 42 is indirectly cooled by the cooling duct 40,
Frost is unlikely to occur. Further, when frost is formed, the frost collects on the moisture permeable member 42. Therefore, when the compressor 29 is not operating, the temperature in the vicinity of the moisture permeable member 42 is set to a temperature at which the frost melts.
The frost is melted by controlling the damper thermo 21 for use. The dew melted from the lower part of the moisture permeable material 42 absorbs water and evaporates from the upper part. Therefore, defrosting is possible without a heater.

Example 6. The ratio of the cross-sectional area of the cooling duct to the cross-sectional area of the outlet is the cross-sectional area of the first cooling duct 48 and the first
The area of the outlet 45, the cross-sectional area of the third cooling duct 50 and the second
The area of the outlet 44, the cross-sectional area of the third cooling duct 50 and the third
The area of the air outlet 46 and each ratio. For example, in order to set the average air temperature in the low temperature chamber 10 to 0 ° C., the above ratio is
The respective settings are 1:20, 1: 2, and 1:10.
Further, the duct is designed so that the ratio of the ratio is decreased when it is desired to increase the average air temperature in the low temperature chamber 10, and the ratio of the ratio is increased when the average air temperature is desired to be decreased.

Example 7. Low greenhouse temperature 10 outside air temperature Tout
And the air temperature Tin in the low temperature chamber 10 have the following relationship.

[Table 1] In FIG. 13, Tout ≦ T at t _{1 to} t ₂ and t _{3 to} t ₄ .
The relational expression of in holds. Since the air in the low greenhouse 10 is humidified by the steam generated from the food, the lowest temperature portion in the low temperature chamber, that is, the moisture permeable material 4 is maintained while the above equation is satisfied.
2 will be dewed (frost is formed depending on the temperature of the moisture permeable material 42). These relationships are shown in the table below.

[Table 2] The moisture that has condensed on the moisture permeable material 42 moves from the surface of the moisture permeable material 42 at the low temperature chamber 10 side to the outer surface of the low temperature chamber 10 due to the capillary phenomenon,
Contact with dry low temperature outdoor air and evaporate. Further, the frosted water is melted when the temperature of the moisture permeable material 42 enters the positive temperature range, and thereafter, the water is evaporated in the same manner as the dewed water. Compared with the current chilled chamber (non-wrap chilled), the temperature of the moisture permeable material 42 is reduced to − because the entire case is cooled.
The feature of this embodiment is that a heater for defrosting is not necessary because it does not need to be cooled down to about 13 ° C.
