る。2. Description of the Related Art Conventionally, this kind of storage has a storage room formed in an insulated box formed of heat insulating walls, and the storage room is heated by warm air from a heater or the like.
It is configured to keep food and the like warm at a predetermined high temperature such as ° C. By the way, as a heat insulating material of a heat insulating wall, a foam heat insulating material such as a foamed polyurethane as shown in Japanese Utility Model Publication No. 46-12766 has been generally used. The temperature is as low as about + 60 ° C., and there is a problem that deformation and deterioration occur at the high temperature as described above.

もあった。However, since the heat-resistant heat-insulating material such as glass wool has a higher thermal conductivity than the foamed heat-insulating material, a large amount of heat is radiated from the storage room to the outside of the refrigerator. There are problems that the outer surface of the heat insulating box becomes hot and that the power consumption of the heater increases. In order to ensure the same heat insulation performance as that of the foamed heat insulating material, there arises a problem that the thickness of the heat insulating wall is increased and the storage room volume is thereby reduced. Furthermore, since the heat insulating material such as glass wool does not have an action of bonding to the surface material constituting the heat insulating wall like the foam heat insulating material such as foamed polyurethane, the strength of the heat insulating wall is remarkably higher than that of the foam heat insulating material. There was also a problem of lowering.

However, when the temperature in the storage chamber 16 rises to, for example, + 82 ° C., the control device (not shown) cuts off the power supply to the blower 26 and the heater 27 and increases the temperature to + 78 ° C. Is controlled so as to be re-energized when the temperature drops to a lower temperature, so that the inside of the storage room 16 is maintained at a high temperature of + 80 ° C. on average. Thereafter, the dishes cooked in the kitchen are stored on the shelf 18 of the storage room 16, the power supply plug 32 is unplugged, and the refrigerator 1 is moved to the banquet room. To restart the heating operation. And, according to the progress of the banquet, the food is served at the right time.

Also, while moving, the heater 27 and the blower 26 are stopped, but it is a short time,
In addition, since the temperature drop of the storage room 26 is suppressed by the heat insulating effect of the heat insulating box 2, there is no problem. In addition, heater 2
Since the humidifying dish 31 is also heated by the heat generated by the humidifier 7, the humidifying water evaporates, whereby the inside of the storage room 16 is humidified to a predetermined humidity. Therefore, it is possible to prevent the food being dried from being dried and keep the food more delicious.

止され、ヒーター27の消費電力も削減される。As described above, the inside of the storage room 16 is + 80 ° C. on average.
For example, the inner surfaces 12 and 12A facing the storage chamber 16 are heated to a temperature of + 80 ° C. or higher when the temperature is high. However, the glass wool 14 that is filled between the inner surface materials 12 and 12A and the outer middle surface materials 13 and 13A is a high-temperature resistant heat-insulating material, and since the heat resistance temperature is high, the temperature of the inner surface materials 12 and 12A is affected. No deformation or deterioration occurs even at high temperatures. Then, the inner surface materials 13, 13A and the outer surface materials 11, 11A
Are filled with foamed polyurethane 15 having low thermal conductivity, so that the inner surface materials 12 and 12A and the outer surface materials 11 and 1
The heat insulating performance of the heat insulating box 2 and the doors 3 and 4 is remarkably improved as compared with the case where all the glass wool is filled between 1A. Therefore, the thickness of the heat insulating box 2 and the doors 3 and 4 can be reduced to increase the volume of the storage room 16. This also prevents the external members 11 and 11A from becoming abnormally hot, and reduces the power consumption of the heater 27.

Due to the heat insulating effect of the glass wool 14 filled between the inner surface materials 13 and 13A, the temperature of the inner surface materials 13 and 13A is reduced to about + 60 ° C.
The disadvantage that the foamed polyurethane 15 between 1A and 1A is deformed or deteriorated is also prevented. In particular, the foamed polyurethane 15 filled between the inner surface material 13 and 13A and the outer surface material 11 and 11A
Are bonded to them, so that the strength of the heat insulating box 2 and the doors 3 and 4 can be improved as compared with the case where only glass wool is filled.

のである。As described in detail above, according to the present invention, a high-temperature resistant heat insulating material is filled between the inner surface material and the inner surface material of the heat insulating wall facing the storage room where the temperature becomes high. Since the foam insulation is filled between the face material and the outer material, the heat insulation of the heat insulating wall is higher than when all the high temperature resistant heat insulating material is filled between the inner material and the outer material of the heat insulating wall. Performance can be significantly improved. Therefore, the thickness of the heat insulating wall can be reduced to increase the volume of the storage room, and also prevent the outer surface material from becoming hot and contribute to energy saving.

きるようになるものである。Also, due to the heat insulating effect of the high temperature resistant heat insulating material filled between the inner surface material and the inner surface material, the temperature of the inner surface material decreases to the heat resistant temperature of the foamed heat insulating material. There is no inconvenience such as deformation of the foamed heat insulating material between them.
In particular, the foam insulation material is filled between the middle and outer surface materials by the in-situ foaming method and is adhered to them. Strength is also improved. Furthermore, since the middle surface material is interposed between the high-temperature-resistant heat insulating material and the foam heat-insulating material, the pressure at the time of foaming the foam heat-insulating material on site prevents the high-temperature heat-resistant heat material from being crushed. Thereby, the heat insulating performance of the high-temperature resistant heat insulating material can be ensured, and the heat insulating wall can have a uniform thickness.
