Definitions
- the invention relates to a control method for controlling the electric drive motor a pump, in particular the circulation pump of a dishwasher, to various Speeds.
- the invention has for its object a control method of the one described Art to improve so that the speed of the drive motor of a pump automatically is controlled so that a desired for performing an operation Delivery pressure of the pump is reached.
- the object is achieved according to the invention in that the drive motor periodically back and forth between an upper and a lower speed is, before the respective up control from the lower to the upper speed the drive motor is briefly switched off. Because of such control result in pressure pulses for the medium conveyed by the pump, the the pressure inherent in the pressure impulses is substantially higher than the pressure at more uniform Advancement. By briefly switching off the drive motor, enough can be done Collect liquid so that when the drive motor is subsequently started up to the upper speed because of the sufficiently available Amount of liquid also the maximum possible pressure is reached.
- High pressure pulses can be generated with a relatively low expenditure of energy that the drive motor immediately after reaching the upper speed controlled back lower speed and operated at the lower speed for a certain time becomes. Since the upper speed only occurs for a very short time, this is also the case required drive power correspondingly low.
- the drive motor of their circulation pump by means of the control method according to at least one of the claims 1-3 is controlled.
- a pulsating spray can be generated due to its periodically increased jet pressure, a significantly better cleaning result is achieved.
- higher jet pressure also very stubborn dirt residues detached from the dishes to be cleaned. While The loosened dirt can be removed in the time following the increased jet pressure transported away by the flushing liquid then sprayed on at a lower pressure become.
- the circulation pump can be opened when starting up the upper or maximum speed is a maximum pressure for spraying the washing liquid achieve with certainty that the time for the brief shutdown of the Drive motor depending on the time for the re-accumulation of a certain one Amount of liquid in the lower area (pump bowl) of the dishwasher rinse tank is measured. This ensures that when starting up the circulation pump has sufficient liquid and no air is sucked in is, which would result in a reduction in the delivery pressure.
- Such periodic control can be particularly advantageous for the circulation pump use in a dishwasher.
- a high spray jet pressure is applied to an upper or its maximum permissible speed 1 achieved, which also causes a detachment of very firmly adhering dirt parts, so that ultimately the cleaning result of a dishwasher is significantly improved.
- Starting up the drive motor to the upper or the maximum permissible speed 1 can be achieved with relatively little effort. The same applies to periodic switching between the two speeds 1 and 2 and the short-term shutdown 4 of the drive motor.
- flushing liquid can get in accumulate in the lower area of the dishwasher's washing container so that Sufficient rinsing liquid when the circulation pump is started up again is available in order to reduce the delivery pressure Avoid sucking in air with certainty.

Claims (5)
- Steuerverfahren zum Steuern des elektrischen Antriebsmotors einer Pumpe, insbesondere der Umwälzpumpe einer Geschirrspülmaschine, auf verschiedene Drehzahlen,
dadurch gekennzeichnet, dass der Antriebsmotor periodisch zwischen einer oberen und einer unteren Drehzahl (1 bzw. 2) hin- und hergesteuert wird, wobei vor dem jeweiligen Hochsteuern von der unteren zur oberen Drehzahl (2 bzw. 1) eine kurzzeitige Abschaltung (4) des Antriebsmotors erfolgt. - Steuerverfahren nach Anspruch 1, dadurch gekennzeichnet, dass der Antriebsmotor unmittelbar nach Erreichen der oberen Drehzahl (1) auf die untere Drehzahl (2) zurückgesteuert und für eine gewisse Zeitspanne (3) mit der unteren Drehzahl (2) betrieben wird.
- Steuerverfahren nach Anspruch 2, dadurch gekennzeichnet, dass die obere Drehzahl (1) der für den Antriebsmotor maximal zulässigen Drehzahl entspricht.
- Geschirrspülmaschine, dadurch gekennzeichnet, dass der Antriebsmotor von deren Umwälzpumpe mittels des Steuerverfahrens nach mindestens einem der Ansprüche 1-3 gesteuert ist.
- Geschirrspülmaschine nach Anspruch 4, dadurch gekennzeichnet, dass die Zeit für die kurzzeitige Abschaltung (4) des Antriebsmotors in Abhängigkeit von der Zeit für das Wiederansammeln einer bestimmten Flüssigkeitsmenge in dem unteren Bereich (Pumpentopf) des Spülbehälters der Geschirrspülmaschine bemessen ist.
