The water hits the collision ribs 60a to 60d of the stopped jet nozzle and restarts the rotation.

Further, during the above-mentioned washing and rinsing steps, the blower 25 of the water / blowing pump 20 also operates, but since the blowing force thereof is weak, the washing water in the blower pipe 34 is hardly affected. Further, since the cleaning water sprayed from the spray nozzles 50a to 50c and the side spray nozzle 70 is diffused,
Bubbles are contained in the wash water that has dropped into the water storage tank 5, but these bubbles are blocked by the bubble cutting cover 14 provided in the water storage tank 5 in the vicinity of the water supply port 19a to the water supply pump 22, and the water supply pump 22 It is not sucked in.

After rinsing and draining the desired number of times, the heater 10 and the motor 21 of the water / blowing pump 20 are energized with the washing water supply pipe 8 closed, and the blower 25 is driven to wash from the blowing pipe 34. Air is sent into the tank 4, and this air is heated by the heater 10 to become warm air, and the dishes 90
Then, the heating process for the entire area of the cleaning tank 4 is started. When the desired time has elapsed, the energization of the heater 10 is stopped and the drying process is completed, whereby all the dishwashing / drying processes are completed. When the tableware 90 has cooled, the upper door 2 and the lower door 3 are opened, the tableware 90 is taken out, and the residual food filter 13 is taken out and the accumulated residual food is discarded. If necessary, the filter 11 is taken out and washed to wash away the residual food.

During the cleaning and drying steps, the temperature of the cleaning water and the warm air is detected by the temperature sensor 15.
It is controlled to an appropriate temperature based on the detected temperature. When the temperature of the heater 10 rises abnormally for some reason,
The overheat protector 16 operates to turn off the power of the heater 10.
