The present application relates to a system for dispensing a detergent solution from a solid detergent into a dishwasher said dishwasher comprising a washing chamber and being capable of performing cleaning cycles each including washing and rinsing periods; the system including a dispenser for dissolving solid detergent blocks and dispensing detergent solution, wherein the dispenser is configured to accommodate solid detergent, to be removably retrofittable into the dishwasher, and, to allow continuous release of all detergent solution as it is formed. In various applications the system may include a battery-powered control unit and a conductivity sensor, configured to measure the conductivity of the washing liquid and to provide the measured conductivity value to the control unit, said control unit is configured to process the conductivity value and to produce a signal.

System for dispensing a detergent solution from a solid detergent into a dishwasher comprising a dispenser

A diaphragm pump (), in particular for use as a detergent dosage pump, comprises a pump housing () with at least a first check valve () and a second check valve (), a fluid chamber (), a diaphragm () defining a wall of the fluid chamber () and reciprocatingly movable, a stepping motor () as driving means for reciprocating said diaphragm (), wherein the stepping motor () comprises a controller () for actuating the stepping motor (), and an external control unit () for operating the controller () of the stepping motor (), wherein the external control unit () is connected to the controller () by a power supply line () for transmitting an operating signal () to the controller (), wherein the operating signal () is a start signal for operating the diaphragm pump (), in particular the stepping motor (), at preset parameters. The diaphragm pump () according to the invention offers increased cost efficiency of the diaphragm pump () by integrating the power supply and the transfer of operating signals from the control unit () to the controller ().
