SANGIORGIO TEMA 798 YEAR 1982.

The machine SANGIORGIO  TEMA 798    is illustrated in the figures but typically it can comprise a drum mounted on a shaft in bearings so as to be rotatable on a horizontal axis within a liquid containing cylinder which is suspended by means of cooperating springs and dampers within an outer cabinet. A AC electric drive motor of the INDUCTION-type is secured to the liquid containing cylinder and is drivingly connected by means of a `V` or multi-V belt-drive system to a pulley wheel secured to the drum shaft outside the liquid cylinder. The system is such that the drum is rotated at a speed below the motor speed and in a fixed relationship of say 1:18 or thereabout. Liquid may be supplied to the cylinder through an electromagnetically actuated inlet valve and removed by an electric motor-driven pump. Liquid in the cylinder may be heated by an electric sheathed wire heating element mounted in a lower wall of the cylinder, the heating element being disposed within the cylinder.


In operation of the washing machine its various functions are sequentially controlled by a program controller comprising a synchronous electric timer motor actuating, via a stepping linkage, a number of cams and hence switches which control the supply of electrical power to the various parts of the machine in sequence so as to cause a particular program of operations to be performed on clothes placed in the drum, and a solid state switching circuit, also controlled by the timer motor for the drive motor of the machine, which controls the wash speed and spin of the drum motor.
