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 achieved.
- the object is achieved according to the invention in that the drive motor periodically back and forth between an upper and a lower speed becomes. Due to such a control, this results from the pump conveyed medium pressure impulses, the pressure inherent in the pressure impulses is much higher than the pressure with even delivery.
- the generation of high pressure pulses therefore requires a relatively small amount of energy, that the drive motor turns on immediately after reaching the upper speed the lower speed controlled and for a certain period of time with the lower Speed is operated. Because the top speed only occurs for a very short time the drive power required for this is 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 jet 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.
- 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.
