Patent number: 4934563Abstract: A cleanser feeding mechanism has a cleanser housing portion, a cleanser feeding member for feeding a cleanser housed in the cleanser housing portion, and a synchronous motor for applying a drive force to the cleanser feeding member, and feeds an amount of cleanser corresponding to the number of revolutions of the synchronous motor. A cleanser feeding amount-setting unit sets an amount of cleanser to be fed from the cleanser feeding mechanism. A driving unit applies an AC source voltage of an AC power source to the synchronous motor. A counter counts the number of cycles of the AC source voltage from a timing at which the AC source voltage is applied to the synchronous motor. A reference cycle number-setting unit sets a total cycle number of the AC source voltage which corresponds to a cleanser amount set by the cleanser feeding amount-setting unit.Type: GrantFiled: April 21, 1989Date of Patent: June 19, 1990Assignee: Kabushiki Kaisha ToshibaInventors: Fumio Torita, Naotaka Ikeda, Kimihiko Nakamura, Katsuharu Matsuo, Tomio Hotta, Yoshiyuki Makino

Patent number: 4862710Abstract: A motor load detector detects an electrical value representing a rise characteristic of a motor, which varies in accordance with a load acting on the motor serving as a power source for a series of operations including a wash cycle and a spin-drying cycle executed by an electric washing machine for washing and spin-drying. A determining section receives a value detected by the motor load detector during the spin-drying cycle, and determines a weight of washings contained in the electric washing machine in accordance with a time which has elapsed until the detected value reaches a second reference value from a first reference value. The determined washings weight is used in a cycle subsequent to the spin-drying cycle.Type: GrantFiled: December 2, 1987Date of Patent: September 5, 1989Assignee: Kabushiki Kaisha ToshibaInventors: Fumio Torita, Naotaka Ikeda, Kimihiko Nakamura, Katsuharu Matsuo, Tomio Hotta, Yoshiyuki Makino

Patent number: 4464914Abstract: An automatic washer of the present invention for automatically carrying out a series of steps of the washing operation comprises a rotary basket provided with a number of holes which permit liquid supplied to the basket to flow therethrough and holding the material to be washed throughout the washing operation, a tub fixed in a manner to surround the basket, and a spraying device mounted to a tub cover and positioned above the upper opening of the basket. During the dehydration-rinsing or centrifugal rinsing step, fresh water is sprayed from the spraying device into the region along the side wall of the rotary basket.Type: GrantFiled: June 14, 1982Date of Patent: August 14, 1984Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventor: Fumio Torita

Patent number: 4335592Abstract: With an automatic washer embodying this invention, a stirring blade member is rotatably provided in a basket set in a tub. A torque of a motor is transmitted to the stirring blade member by means of a drive transmission. A water supply control system is set in a central processing unit. Where wash water is filled in the tub to a predetermined or standard level, then a water valve is closed. A number of rotations of the stirring blade member in the wash water in which material of washing is dipped is detected by a rotation detector. A length of time for which the water valve is to be left open is determined from the number of rotations of the stirring blade member. The water valve is left upon for a calculated length of time.Type: GrantFiled: November 25, 1980Date of Patent: June 22, 1982Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventor: Fumio Torita
