Abstract

The washing-agent dispensing device has a pump (97) with an inlet for a washing agent and an outlet which is connected to a container, from which a liquid consisting of washing agent and water can be removed for washing tableware, and a control device for controlling the pump (97). The control device has a sensor device and a control circuit (112) which can be set in operation by the sensor device. The sensor device is designed as a bridge circuit, one branch of which is arranged with electrodes (135, 137) for measuring the electric conductivity of the liquid in the container. Depending upon the conductivity of the liquid, the pump (97) is controlled via a controllable switch (Q1) in the bridge circuit and the control circuit (112), in order to supply washing agent and to keep the washing-agent concentration of the liquid in the container constant. <IMAGE>
