Next, the operation of the above configuration will be described. The door 23 is opened as shown in FIG. 1 and the dishes to be washed are stored in the dish basket 14 in the washing tank 11. At this time, a detergent is charged into the cleaning tank 11. Thereafter, when the door 23 is closed and a start switch (not shown) is operated, the water supply valve 16 is opened to supply water to the cleaning tank 11 to a predetermined water level. After this water supply, the heater 12 generates heat and the water in the cleaning tank 11 is heated. Is heated to about 60 ° C. to make it hot water (water supply / heating step).

When the water supply / heating process is completed, the cleaning pump 19 is started to draw hot water in the cleaning tank 11 from the water suction port 18 and send it to the injection arm 13 under pressure. As a result, the spray arm 13 rotates and sprays warm water containing a detergent as washing water toward the dishes in the dish basket 14 to rotate the dishes (washing process). When the washing step is performed for a predetermined time, the drain pump 20 is started, and the water in the washing tank 11 is sucked from the suction port 18 and discharged to the drain pipe (not shown) of the sink 3 (drain step).

After the drainage is completed, the same water supply and heating steps as described above are performed again, and the washing pump 19 is started to inject hot water from the injection arm 13 to rinse the dishes (rinse step). When the rinsing process is completed, the drain pump 20 is activated to discharge the water in the washing tank 11 (a drain process). Thereafter, the blower 21 and the heater are driven, and the outside air blown into the cleaning tank 11 by the blower 21 is heated and heated by the heater 12 to dry the dishes (drying process). When the drying step is completed, the washing operation including the above series of steps is completed.

When the door 23 is opened during such a cleaning operation, the opening operation of the door 23 is detected by the Hall IC 46. Then, the control device immediately stops the cleaning operation. Then, when the door 23 is closed, this is
