Definitions

  • the invention relates to a method according to the preamble of claim.
  • the system speed determines a mass moment of inertia of the loaded with the laundry drum approximately proportional characteristic, which in turn the difference of the torques for a constant drum speed and for a current Acceleration of the drum speed proportional and the current angular acceleration is inversely proportional.
  • the present invention is based on the technical problem to achieve a more accurate statement about the current load of the laundry drum for better optimization of the spin speed on the detection of the electrical power consumption of the drive motor for the drum rotation.
  • the power measurements during the two different constant speeds and over the duration of the final acceleration phase to be measured are advantageously carried out in a known manner by voltage and current measurement at the DC link for a controllable frequency or voltage converter for speed control of a synchronous or asynchronous working AC induction motor or a DC universal motor as the drum drive.
  • the potential energy at the higher speed n1 (as product of mass moment of inertia and angular velocity) is proportional to the sum of the potential Energy at the lower speed n2 and the energy absorption Eb during the acceleration phase III minus the design-related friction energy during the acceleration phase, ie the product of the average of the two measured friction losses P1, P2 and the duration tb of the acceleration phase III.
  • the procedure according to the invention produces a reproducible characteristic value for the current drum load and thus dependent on constructive machine data for a speed limit optimized in this regard when accelerating the laundry drum to the highest possible spin speed.

  1. Procédé de détermination de la charge du tambour d'une machine de traitement du linge par la détermination du moment d'inertie du tambour chargé de linge à partir de la puissance électrique absorbée par le moteur d'entraînement pour le tambour tournant à différentes vitesses de rotation au-dessus de la vitesse de rotation de l'installation, caractérisé en ce que l'on mesure la puissance électrique absorbée du moteur à une première vitesse de rotation constante puis à une deuxième vitesse de rotation constante mais inférieure et ensuite pendant une phase d'accélération, pendant laquelle la vitesse de rotation augmente de nouveau jusqu'à la première vitesse de rotation constante, avec formation de la différence entre l'énergie absorbée pendant la phase d'accélération (Eb) d'une part et d'autre part le produit de la durée d'accélération (tb) par la valeur moyenne des deux puissances de friction (P1, P2) de la rotation du tambour, mesurées à des vitesses de rotation constantes avec un essorage préalable constant.
