摘要： A device for avoiding unbalance during acceleration to spindrying. A water level sensor has an additional contact through which a control voltage which is derived from a motor speed regulator is fed, and interrupts the motor supply if the drum speed decreases below a predetermined value. Spindrying cannot commence until after the tub is filled and an operating sequence at washing speed has taken place.

摘要： A method of controlling the operation of a d.c. motor of a washing machine by energizing or de-energizing a reference voltage generator. The back-e.m.f. of the motor is compared with the reference voltage. The a.c. supply of the generator is controlled by contacts of detectors for the operating conditions of the machine, such as temperature of the suds or of electronic components, unbalance, opening of the door etc.
