Abstract

PROBLEM TO BE SOLVED: To effectively prevent the washing from flying out by arranging, on the opening part of a water tank, an optical sensor consisting of a light projecting part and a light receiving part arranged opposite to each other with the opening part, and stopping the rotation of a spin basket when the flying out of the washing from the spin basket in dehydrating process is detected. SOLUTION: When a spin basket 8 and a pulsator 9 are rotated at high speed by motor 5 after the rinsing of the washing housed in the spin basket 8 is finished, the washing is dehydrated. When the washing flies out from the opening part 8a of the spin basket 8, the light is temporarily shielded by the washing, and the light from a light projector 14b is not incident on a light receiver 15b, or the incident quantity is significantly reduced. A control device 13 judges from this that the washing partially flies out from the spin basket 8. On the basis of this judgment, the feed to the motor 5 is stopped, and the brake mechanism of a rotation control mechanism 6 is operated to perfectly stop the rotation of the spin basket 8.

[0005] This fully automatic washing machine
Dehydration is performed as follows. First, the lid 2 is opened, a predetermined amount of water and a detergent are charged into the water tank 3, and mixed well. Subsequently, the laundry is stored in the dewatering tub 8, the dewatering cover CV is attached to the opening 8 a of the dewatering tub 8, and the lid 2 is closed. When the switch is turned on, the motor 5 rotates under the control of the control device 13. The rotation of the motor 5 is transmitted to a rotation control mechanism 6 via a belt 7. The mode of the rotation control mechanism 6 is set so that only the pulsator 9 is rotated by the clutch operation. Accordingly, the rotation of the pulsator 9 is controlled based on the rotation of the motor 5, whereby the laundry is washed. Next, when the washing is completed, the drain valve 12 is opened by the control device 13, the washing water is discharged, and the rinsing is performed. When the rinsing is completed, the rotation control mechanism 6 is switched to a mode in which the dewatering tub 8 and the pulsator 9 rotate by a clutch operation based on a command from the control device 13. When the switching is completed, the rotation of the motor 5 is transmitted to the dewatering tank 8 and the pulsator 9, and both rotate at high speed. Thereby, the laundry is dehydrated. After a certain period of time, when the rotation of the motor 5 is stopped, the control device 13 simultaneously activates the brake mechanism to apply a brake to the rotation of the dewatering tub 8, and the rotation is stopped in a short time.
After that, the lid 2 and the dehydrating cover CV are opened, and the laundry and dehydration are completed by taking out the laundry.
