Abstract

In einer Geschirrspülmaschine ist eine Einrichtung (23) zum Ermitteln des Verschmutzungsgrades einer Spülflüssigkeit umfaßt. Um den tatsächlichen Verschmutzungsgrad der Spülflüssigkeit ohne Verlängerung des Spülprogrammes messen zu können, ist erfindungsgemäß die Ermittlung des Verschmutzungsgrades während eines ununterbrochenen Reinigungsvorganges bei annähernd unbewegter Spülflüssigkeit durchführbar.In a dishwasher, a device (23) for Determine the degree of contamination of a rinsing liquid includes. To the actual degree of pollution of the Measure the rinsing liquid without extending the rinsing program According to the invention, the determination of the Pollution levels during an uninterrupted Cleaning process with almost immobile Rinsing liquid can be carried out.

Insbesondere ist durch eine Umsteuereinrichtung (13) die Spülflüssigkeit wenigstens zwei voneinander getrennten Kanälen (15, 17) zuführbar und die Messung des Verschmutzungsgrades kann in einem dieser Kanäle erfolgen, während ein anderer Kanal von der Umsteuereinrichtung (13) angesteuert ist.

Figure 00000001
In particular, the rinsing liquid can be supplied to at least two channels (15, 17) separated from one another by a reversing device (13) and the degree of contamination can be measured in one of these channels, while another channel is controlled by the reversing device (13).
