A container 1 is placed on the main body 2, and an upper opening of the container 1 is covered with a lid 5 to form a drying chamber 6. The bottom 3 is provided with a heater 7 and an electric motor 8 as a drying means for heating and drying the tableware stored in the container 1.
And a warm air generator 10 including a fan 9 is provided,
On the front side of the bottom portion 3, a microcomputer (not shown) for controlling the warm air generator 10, a measuring means 11 including a thermistor for measuring the room temperature, and a display LED 12 for displaying an operating state.
An operation unit 13 having is provided. The water receiving plate 4 is attached so as to cover the upper opening of the bottom part 3, has an outlet 14 for introducing the warm air from the warm air generator 10 to the container 1 in a substantially central portion, and is dried above and behind the electric motor 8. Room 6
Has a vent hole 15 for returning a part of the air to the inside of the main body 2, and a cover 16 is attached to the upper part of the vent hole 15 so that water from the water receiving plate 4 does not enter the main body 2. Inside the main body 2 of the vent hole 15, a measuring means 17 including a thermistor for measuring an air temperature in the drying chamber 6 (hereinafter abbreviated as air temperature) is provided.

The operation of this embodiment having the above structure will be described.

Here, all the measured information is input to a microcomputer (not shown) to output and control the results of judgment, calculation, comparison, etc., and the letters of the microcomputer are omitted in the following description.
