Abstract

The dishwashing machine includes a centrifugal pump for spraying water into the washing chamber. This pump is driven by a single phase electric induction motor (1) with principal (M) and auxiliary windings (A). These have a common terminal (2) connected via a switch (3) controlled by the programmer, and a further switch (4) operated by the loading door to the supply. The second terminals of the two windings are connected to a control circuit (8) having three outputs (8a,b,c). This circuit controls the current supplied to the windings by chopping the waveform of the a.c. voltage. This control is effected using an integrated circuit within the control circuit. The current supplied to the motor is initially limited so that there is not a surge of hot water into the cold washing chamber. This prevents the rapid build up of vapour raising the pressure as the hot water comes into contact with the cold surfaces.
