とができるものである。According to the first means of the present invention, since the ultrasonic wave generator is provided in the circulation path of the circulating washing water, ultrasonic waves are added to the shower-like washing water discharged to the washing tub.
When the shower to which the ultrasonic wave is added is poured into the laundry in the washing tub, the ultrasonic wave and the cavitation effect exert an extremely large detergency. The cleaning effect by the ultrasonic wave exerts a great effect because it acts locally concentratedly, and the energy of the ultrasonic wave itself is small and does not give the laundry a force that damages the laundry. The cleaning performance can be improved without increasing the damage.

The foam in the washing water has a large amount of detergent components, that is, surfactants, concentrated on its surface. When the shower in which the foam is present is poured into the laundry in the washing tub, the surfactant having a high concentration on the foam surface effectively acts on the soil of the laundry and exerts a large detergency. In addition, the foam in the washing water can serve as a cushion for the laundry to reduce the damage of the laundry and improve the cleaning performance.

に部分洗いが可能となる。The operation of the embodiment will be described below. First, the user puts laundry in the washing tub 2 and puts a predetermined amount of detergent into the detergent container 13 according to the amount of the laundry. Thereafter, the water supply valve 11 is energized for a predetermined time, and water is supplied into the washing tub 2 together with the detergent in the detergent container 13 to store a predetermined amount of washing water.
At this time, when the pump 15 is operated, the washing water in the washing tub 2 is absorbed from the drain port 13, passes through the circulation path 17, and returns to the washing tub 2 from the discharge port 18 as a shower. Here, when the ultrasonic generator 19 is driven, the shower to which the ultrasonic wave and the foam are added is directly poured into the laundry. Since the detergent supplied together with the water supply into the washing tub 2 was not completely dissolved and stayed on the laundry, the detergent to which the ultrasonic wave was added can dissolve the detergent in an extremely short time. . As a result, the ability of the detergent can be sufficiently exhibited from the beginning of washing, and the washing performance can be greatly improved. Further, when a predetermined amount of washing water is supplied, the pulsator 5 is driven to rotate by the motor 7 and washing is performed for a predetermined time. Even during this washing, the shower to which the above-mentioned ultrasonic wave is added is applied to the laundry floating on the upper portion of the washing tub. At this time, the shower to which the ultrasonic wave is applied exerts an extremely large detergency on a local portion of the laundry hit by the ultrasonic vibration and the cavitation effect. The cleaning effect by ultrasonic waves exerts an extremely large effect because it acts locally and concentrated, and the energy of the ultrasonic waves itself is small and does not give the laundry the power to damage the laundry, so the damage of the laundry The cleaning performance can be significantly improved in combination with the above-described detergent dissolution accelerating effect without increasing the value. In addition, during the operation of the ultrasonic generator 19, the shower to which the ultrasonic wave is added is applied to the laundry to which the dirt is extremely firmly adhered, for example, the collar sleeve of the shirt, so that the ultrasonic generator 19 can be easily and extremely easily applied. Partial washing becomes possible in a short time.
