Abstract

1279057 Washing machines PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 12 Nov 1970 53890/70 Heading D1A In a method of using a washing and spin drying machine comprising a resiliently mounted tub accommodating a drum, which is rotatable about a horizontal spindle by a twospeed electric motor through a variable-ratio transmission, and having water supply and drain means, after the washing operation (at 50 r.p.m.) when the motor is changed over to a spin drying speed and the drum is accelerated with the tub still full of water distribution speed (200 to 300 r.p.m.) is attained at which the torque delivered to the drum spindle and the reaction torque are balanced, this balance being maintained until the water is driven into rotation when the drum accelerates again to a final speed of 1000 r.p.m. when the water is drained. The distribution speed is above the range of critical speeds between 100 r.p.m. and 160 r.p.m. for vibrations about the three perpendicular axes of the drum. The drain pump may be actuated when the motor is changed to the spin drying speed or when the distribution-speed is attained as there is an effective lag in its operation. The motor may be a 2/8 pole pole changing motor, or a D.C. motor driven through a rectifier and preferably in series with a heater in the machine tub. The transmission preferably includes an expanding belt pulley sensitive to the motor speed.
