At this time, the washing water is directly applied to the laundry in the washing / dehydrating tub 4 and, together with the stirring by the stirring blades 5, the washing water is evenly permeated into the laundry and the washing efficiency is improved, so that washing with less water causes no uneven washing. Since efficient washing can be performed, and moreover, washing water or rinsing water can be efficiently permeated into the laundry, the strength of the water flow due to the stirring of the stirring blades 5 can be made a weak water flow. It is also possible to reduce the noise caused by.

The configuration of the second embodiment of the fully automatic washing machine of the present invention is almost the same as the configuration of the first embodiment, and the control unit 26 responds to the result of detection of the amount of laundry at the time of performing cyclic washing or rinsing. It has a circulation pump drive start control function for driving the circulation pump when the water level sensor detects a water level lower than the corrected water level corrected by
When it is possible to set 5 levels of 3, 4 and high, if the normal set water level according to the detected amount of laundry is the "high" water level, the corrected water level for circulating washing is this water level. When the water level becomes "4", which is one step lower, and the water level in the water tank 2 becomes "3", which is one step lower than the water level of "4", the circulation pump 2
9 is started.

If it is a "high" water level, it will be corrected to a water level of "4" which is one step lower than this water level, and a water level of "3" that is one step lower than this corrected water level of "4", that is, 2 more than the set water level. When the water level becomes lower, the circulation pump 33 is driven to circulate the wash water. By circulating this washing water, the washing water can be penetrated into the laundry and the detergent can be dissolved before the stirring blade 5 is stirred.

できる。In the fully automatic washing machine according to the first aspect of the present invention, the washing water is circulated by circulating the washing water from the bottom of the aquarium and through the circulation pipe to the top of the washing and dehydrating tub. As a result, the washing water in the washing and dewatering tub is directly applied to the laundry, and the washing water is evenly permeated in combination with the stirring by the stirring blades, and the washing efficiency is improved. You can do good cleaning, and
Since the wash water or rinse water is efficiently permeated into the laundry, the strength of the water flow caused by the stirring of the stirring blades 5 can be made weak and the noise caused by the water flow can be reduced.
