PURPOSE: To heat a plate to be served to a customer, etc., without taking much time in a restaurant.

CONSTITUTION: The inside of a main body 1 whose front plane is opened forms a tableware housing part 3. The plate D can be placed in piles upward/ downward at both right and left side parts of the tableware housing part 3, respectively. A pair of right and left lengthy fans 21 and heaters 24 are provided vertically in the rear center of the main body 1. An air current from the fan 21 goes to hot wind passing through the heater 24, and it is sprayed to the tableware housing part 3, which heats up the plate D. The hot wind flows so as to go around the right and left plates D by the guidance of the inner face of the tableware housing part 3 and a door 6. Therefore, a device itself can be compacted by arranging the tableware housing part 3, the upward/ downward lengthy fan 21 and heater 24.
