The first rinsing is performed by rotating in the forward direction. When the first rinsing operation is completed after a certain period of time, the dust extraction solenoid (44) is activated, and the spring (18) moves the dust case (20) to the outside of the wash water circulation path as shown in FIG. In addition to waiting, the water in the tank (14) is replaced to perform the second rinsing operation and the third rinsing operation as in the first rinsing operation.

The auto lock motor (68) is operated so that the lock is turned on, and the notch (66) of the lid cover (5) moves from the lock body (67).
When the above cleaning operation is performed by operating the start switch (34) while escaping the
The auto lock motor (68) is operated so that the lock is turned on, the lock body (67) is retained in the notch (66) of the lid cover (5), and the lid cover (5) is fixedly supported at the closed position. ,
It prevents the lid cover (5) from opening during cleaning.

のである。"Effects of the Invention" As is clear from the above embodiments, according to the present invention, the tableware is dried by drying the tableware by discharging the compressed air from the fountain blades (23) into the washing chamber (6) by the idle operation of the water pump (25). The washing machine is provided with a blower fan (63) for sending outside air to the water intake port of the water supply pump (25). Since the blower fan (63) forcibly sends outside air to the water intake port of the water supply pump (25). , The air blowing action of the water supply pump (25) is greatly promoted, and the air in which the air in the cleaning chamber (6) is mixed with the outside air is discharged from the fountain blade (23) into the cleaning chamber (6) and dried. The time can be greatly shortened, and by only incorporating the blower fan (63) into the structure for cleaning, the drying function can be improved without losing the effect of drying by the cleaning structure. It has a remarkable effect.
