Definitions
- the invention relates to a method according to the preamble of the claim.
- the present invention is technical Problem based, in order to better optimize the spin speed by detecting the electrical power consumption of the drive motor for the drum rotation a more precise statement about the current load to achieve the laundry drum.
- the power measurements during the two different constant speeds and the duration of the final acceleration phase to be measured are advantageously carried out in a manner known per se by means of voltage and Current measurement on the DC link for a controllable frequency or voltage converter for influencing the speed of a synchronous or asynchronous working three-phase AC motor or a DC universal motor than the drum drive.
- That proportionality factor for the current drum loading and therefore also for the maximum permissible drum speed is determined during the Operation of the machine driving the laundry drum when reaching a first Speed n1 temporarily held constant (phase I in the speed-time diagram the drawing).
- the electrical drive power consumed in the meantime P1 is due to the design, in particular the mechanical friction proportional to the drum bearing.
- the electric drum drive is initially set to a phase I lower speed n2 of the laundry drum braked or let it run out, which in turn is then kept constant during the current measurement phase II again, now for this lower speed n2, via the electrical power consumption P2 of the drive motor for the drum whose design is now determined To determine the power requirement.
- the potential is Energy at the higher speed n1 (as a product of the moment of inertia and angular velocity) proportional to the sum of the potential Energy at the lower speed n2 and the energy consumption Eb during acceleration phase III minus the design-related friction energy during the acceleration phase, i.e. the product of the mean of the both measured friction powers P1, P2 and the duration tb of the acceleration phase III.
- Phase III since in this proportionality factor apart from the determination of the duration Phase III only receive electrical power measurements that are in the DC intermediate circuit as current and voltage measurements easily and accurately are feasible, the procedure according to the invention results in a reproducible Characteristic value for the current drum load and thus dependent on the design Machine data for an optimized speed limit when accelerating the laundry drum to the highest possible spin speed.

Claims (1)
- Verfahren zum Bestimmen der Beladung der Trommel einer Wäschebehandlungsmaschine durch Ermitteln des Massenträgheitsmomente der mit Wäsche beladenen Trommel aus der elektrischen Leistungsaufnahme des Antriebsmotors für die bei verschiedenen Drehzahlen oberhalb der Anlagedrehzahl rotierenden Trommel,
dadurch gekennzeichnet, dass die aufgenommene elektrische Leistung des Motors bei einer ersten konstanten und dann bei einer zweiten, dagegen niedrigeren konstanten Drehzahl sowie hieran anschließend während einer Beschleunigungsphase gemessen wird, während welcher die Drehzahl wieder bis auf die erste konstante Drehzahl ansteigt, mit Bilden der Differenz aus der Energieaufnahme während der Beschleunigungsphase (Eb) einerseits und andererseits dem Produkt der Beschleunigungszeit (tb) mit dem Mittelwert aus den beiden bei konstanten Drehzahlen mit konstanter Vorentwässerung gemessenen Reibleistungen (P1, P2) der Trommeldrehung.
