The inside of the duct 15, particularly the inner surface of the vertical portion 15A, is a radiation surface 30 which is heated by the heater 23 and emits thermal radiation. The radiation surface 30 is a far-infrared panel formed by sintering a ceramic on the surface of a stainless steel plate, and according to this far-infrared panel, emits far-infrared rays as thermal radiation when heated. Therefore, the table stored in the heat insulation room can be appropriately kept warm by the radiant heat. Note that the entire inner surface of the duct 15 including the inner surface of the horizontal portion 15B may be a radiation surface. Here, although not shown in the figure,
A heat insulating material such as glass wool is provided between the outer surface facing the radiation surface 30 and the heater 23 to prevent heat conduction to the outside. The heater 23 is a sheathed heater in which a heating wire that generates heat by energization is housed in a tubular body. Good.

The humidifying section 33 has a heater panel 34 provided on the lower surface of the heat retaining chamber 10 with water contained therein. Installed in In particular, the humidifying section 33 is installed in a state close to the exhaust port 18 of the duct 15 so that the water heated by the heater panel 34 can be diffused as steam into the heat retaining chamber 10 together with the warm air flowing out of the exhaust port 18. ing. Here, the heater panel 34 is heated by energization. However, when the intake port 17 and the exhaust port 18 of the duct 15 are closed, the energization of the heater panel 34 is automatically or manually stopped. In FIG. 6,
Reference numeral 35 denotes an opening / closing door provided in a cool room or a warm room.

A plurality of meals are stored in the storage box 4 supported by the shelf plate 7, and particularly, in the cool room 9, the meals are stored. Salad, milk and other beverages are stored as
Stores hot food such as boiled foods and fried foods. And
These meals are kept at an appropriate temperature by the refrigerator 8 in the cool room 9 and are kept at the proper temperature by the warming means in the warm room 10.

Then, the air in the duct 15 is circulated by the fan 16 through the outward path 20 and the return path 21, and is heated by the heater 23 to become warm air. Therefore, the inner surface of the duct 15, that is, the radiation surface 30 is heated by the warm air and the heater 23, and emits far-infrared rays as heat radiation into the heat insulation room 10. As a result, the heat insulation room 10
The inside meal can be kept at an appropriate temperature by the radiant heat.

In addition, the heater panel 34 is energized to generate steam from the humidifier 33. In this case, the air in the heat retaining chamber 10 is sucked into the duct 15 from above by the fan 16 and
After being heated by the heater 23 inside, the exhaust port 18
It flows out into the heat insulation room 10 again. In particular, at the time of outflow, the steam in the humidifying section 33 is accompanied by high-temperature and high-humidity warm air, so that the warming room 10 is kept warm by the warm air to prevent the food from drying.
