Water bearing domestic machine has vibration sensor, circuit with amplifier, rectifier, evaluation element and analog-digital converter providing digital signal for controlling pump

摘要

The machine has a pump for transporting liquid, especially for circulating and pumping out cleaning and rinsing liquid, and an arrangement for detecting vibrations. Signals from a vibration sensor (1) are evaluated during pump operation by a circuit with an amplifier (8), a rectifier (3), an evaluation element (4) and an analog-to-digital converter (5) providing a digital signal (9) for controlling the pump.
