継続運転される。 When the cleaning process is completed, the circulation pump 11 is stopped, and the drain pump 10 is activated to discharge the dirty cleaning water in the cleaning chamber 2 to the outside through the drain pipe 9. When the drainage is finished, the blower 16 is operated to forcefully blow the outside air flowing in from the outside air intake port 17 into the washing chamber 2 through the air passage 18 and the communication port 19.
During this time, the inside of the washing cabinet 2 is heated to a predetermined temperature by the heater 21, and the introduced outside air is discharged to the outside from the exhaust path 20 while absorbing the moisture in the tableware 23. This action continues until the tableware 23 is completely dried.

As shown in the figure, in the normal state, the damper 24 blocks the communication port 19 as shown by the solid line, so water vapor generated from the cleaning water during cleaning does not enter the ventilation path 18 through the communication port 19. do not have. When the cleaning process is completed and the drying process begins, the blower 16 is activated to blow air into the air passage 18. Therefore, the damper 24 is pushed toward the washing chamber 2 by the wind pressure as shown by the broken line, the communication port 19 is opened, and air is blown into the washing chamber 2. The air injected at this time is pushed downward by the damper 24, so it can efficiently hit the heater 21.
Heated more effectively. When the drying process is completed and the blower 16 is stopped, the damper 24 rotates due to its own weight and closes the communication port 19 again.
