Control method for a washing household appliance comprising a drainage pump unit with an impeller and a motor supplied with an alternating supply voltage of a determined frequency from among a plurality of possible preset frequencies. According to one implementation the method involves an adjustment stage in which the frequency of the motor supply voltage is regulated between the preset frequencies. The method also includes an application stage in which a stator voltage is applied to the motor, the frequency of the motor supply voltage being regulated between the preset frequencies in accordance with the stator voltage applied.

Washing appliance and control method thereof

A method for controlling an induction apparatus having an induction coil. In one implementation the induction apparatus includes a capacitor that is connected in parallel with the induction coil to form a parallel resonant circuit, and also includes a switch connected in series with the parallel resonant circuit, between the parallel resonant circuit and a reference voltage. According to one method, a digital test signal dependent on the voltage in a node disposed between the switch and the parallel resonant circuit is generated, the switch is closed for a predetermined closure time and then reopened at the end of the closure time. With the switch reopened, the test signal is evaluated for a predetermined waiting time in order to determine the presence or absence of a vessel on the induction coil.
