- the lid 11 covers the opening of the storage case 10, even if air in the storage case 10 tries to escape to the outside, the storage container has a sealed structure. Is forming. Therefore, the cool air circulating in the vegetable compartment 4 is a sealed space by indirect cooling through the storage case 10 and the lid 11 instead of cooling the storage case 10 by directly flowing into the storage case 10. The inside of the storage case 10 is cooled.
- the storage case 10 is connected to a door 13 shown in FIG. 3 by a fixing part 12 shown in FIG. And the storage case 10 is taken in and out of the vegetable compartment 4 according to opening and closing of the door 13 provided in the front surface of the vegetable compartment 4.

- the cooling unit 22 is exposed from the upper surface of the lid 11.
- the cool air flowing in from the inflow port 6 is radiated and dissipated to transmit the cold heat to the dew condensation unit 23. That is, the cooling unit 22 is directly cooled by cold air.
- the cooling unit 22 uses a material having a higher thermal conductivity than the lid 11, such as copper or aluminum, and can reliably transmit cold heat to the dew condensation unit 23.
- the lid 11 is made of resin and has a lower thermal conductivity than the cooling unit 22. Therefore, since the lid 11 is difficult to transfer heat, the temperature difference between the cooling unit 22 and the inside of the storage case 10 can be maintained.
- the dew condensation part 23 is connected to the cooling part 22 and is provided in a sealed space constituted by the storage case 10 and the lid 11. Since the dew condensation part 23 is cooled to substantially the same temperature as the cooling part 22, the dew condensation part 23 has a temperature lower than the temperature inside the storage case 10. For this reason, moisture in the air in the storage case 10 in contact with the surface of the dew condensation part 23 can be cooled and condensed.
- the dew condensation part 23 is preferably made of a material having a high thermal conductivity like the cooling part 22.
- the spray unit 24 sprays the moisture condensed in the dew condensation unit 23 into the storage case 10. Thereby, moisture reduction, such as vegetables stored in storage case 10, can be controlled, and humidity can be maintained and preservation nature can be improved.

- the cold air flowing into the vegetable compartment 4 from the inlet 6 through the first connection passage 8 from the refrigerator compartment 2 passes through the first cold air passage 29 provided on the outer periphery of the storage case 10 according to the arrow. Then, it passes through the second cold air passage 30 provided on the upper side of the lid 11 according to the arrow, and flows out from the outlet 7 to the cooler via the second connection passage 9 outside the vegetable compartment 4.
- the temperature in the storage case 10 becomes higher than the temperature of the cold air circulating in the vegetable compartment 4.
- the cooling unit 22 of the mist generating device 21 is directly cooled by the cold air circulating outside the storage case 10. Cold heat from the cooling unit 22 is transmitted to the dew condensation unit 23.

Even if the cooling unit 22 is cooled at this temperature, the temperature of the surface of the dew condensation part 23 does not become 0 ° C. or less, so that the dew condensation on the surface of the dew condensation part 23 does not freeze. That is, it is possible to generate condensation at a temperature that does not freeze, without performing precise control such as keeping the temperature so as not to freeze while lowering the temperature of the condensation unit 23 to a temperature that causes condensation.

If it is higher than this, condensation can be generated.
- the temperature in the storage case 10 is about 8 to 10 ° C., there is a sufficient temperature difference against the occurrence of condensation.
- the temperature in the storage case 10 decreases and the difference from the temperature of the dew condensation portion 23 becomes small, such as when the door 13 is not opened for a long period of time, the temperature in the storage case 10 is too low.
- the temperature of the vegetable compartment 4 including the inside of the storage case 10 rises by detecting that the temperature is detected by a temperature sensor or the like and stopping the cool air flowing from the inlet 6.
- a temperature sensor or the like that the temperature in the storage case 10 is equal to or higher than a predetermined temperature, cold air is again introduced into the vegetable compartment 4 from the inlet 6.
- the inside of the storage case 10 is a sealed space and is not directly cooled by the cold air, while the cooling unit 22 of the mist generating device 21 is directly cooled by the cold air circulating outside the storage case 10. For this reason, the cooling unit 22 is cooled earlier than in the storage case 10. Therefore, since the temperature of the dew condensation part 23 is cooled earlier than the temperature in the storage case 10, a temperature difference necessary for the dew condensation part 23 to condense can be generated.
- the mist generating device 21 exposes the cooling unit 22 from the upper surface of the lid 11 and is disposed in the second cold air passage 30, the cooling unit 22 does not impair the effective space of the storage case 10. Absent. Moreover, since the moisture condensed in the dew condensation part 23 connected to the cooling part 22 is sprayed in the storage case 10 using the spray part 24, the water storage tank for storing dew condensation is unnecessary. For this reason, the effective space of the storage case 10 is not impaired.

Thereby, since heat conduction between the outer surface of the lid 11a through which the cold air flows and the inner surface of the lid 11a in contact with the air in the storage case 10 can be suppressed, the cooling unit 22 and the storage case 10 can be compared with the first embodiment. The temperature difference can be effectively maintained.
- the hollow portion is evacuated or a material having a lower thermal conductivity than that of the resin constituting the lid 11a is inserted, it is more difficult to transfer heat, so the temperature difference between the cooling portion 22 and the storage case 10 Can be maintained more effectively.
