Definitions

  • German patent application no DE19832292 in a direct drive washing machine, predicting the load by measuring the position reached by the laundry batch loaded in the drum while the drum rotates and the electric current values of the electric motor is described.
  • a vibration detecting means is used that can detect vibrations in at least two axes for determining the unbalanced load.
  • the phase difference of the signals of the vibration detecting means at two directions and the data of front, rear are used together, the position of the unbalanced load can be found.
  • the sinusodial signals used here are not only generated due to the oscillation of the drum but are also affected by the environmental noise.

Claims (8)

  1. Une machine à laver/sécher (1) qui comprend une cuve (2), un tambour (3) disposé dans la cuve (2), dans lequel le linge est placé, tournant autour d'un axe horizontal (E), un moteur (4) qui tourne ledit tambour (3), un aimant (5), un capteur de position (6) qui génère un signal par l'effet de l'aimant (5), un capteur de vibration (7) et une unité de commande (8) qui détecte la quantité de la charge déséquilibrée (Y) par l'évaluation de l'amplitude (λ) du signal sinusoïdal (S) et réduit le déséquilibre, caractérisée en ce que l'aimant (5) est situé sur le tambour (3), que le capteur de position (6) est disposé sur la cuve (2), qui génère un signal d'impulsion (D) à chaque tour de rotation du tambour (3), que le capteur de vibration (7) est disposé sur la cuve (2), générant un signal sinusoïdal (S) ayant la fréquence de rotation du tambour (3) et que l'unité de commande (8) calcule la position angulaire de la charge déséquilibrée (Y) dans le tambour (3) en mesurant la différence de phase (F) entre le signal d'impulsion (D) et le signal sinusoïdal (S).
  2. Une machine à laver/sécher (1) selon la Revendication 1, caractérisée par une unité de commande (8) où la position de la charge déséquilibrée (Y) au même niveau dans l'axe horizontal par rapport à l'aimant (5) et le capteur de position (6) pour chaque tour de rotation différent est enregistrée comme la position de référence (R) par le fabricant.
  3. Une machine à laver/sécher (1) selon l'une quelconque des revendications précédentes, caractérisée par une unité de commande (8) où la différence de phase (F) entre le signal d'impulsion (D) mesuré et le signal sinusoïdal (S) est enregistrée par le fabricant comme la différence de phase de référence (RF) pour chaque tour de rotation différent lorsque la charge déséquilibrée (Y) est dans la position de référence (R).
  4. Une machine à laver/sécher (1) selon la Revendication 2 ou 3, caractérisée par une unité de commande (8) qui détermine la position angulaire de la charge déséquilibrée (Y) par rapport à la position de référence (R) à partir de la différence entre la différence de phase (F) mesurée lorsque la charge déséquilibrée (Y) n'est pas à la position de référence (R) par rapport à l'aimant (5) et la différence de phase de référence (RF).
  5. Une machine à laver/sécher (1) selon l'une quelconque des revendications précédentes, caractérisée par un aimant (5) qui est disposé sur la poulie à courroie derrière le tambour (3).
  6. Une machine à laver/sécher (1) selon l'une quelconque des revendications précédentes, caractérisée par un capteur de position (6) qui est disposé sur la projection de la trajectoire suivie par l'aimant (5) au-dessus de la cuve (2).
  7. Une machine à laver/sécher (1) selon l'une quelconque des revendications précédentes, caractérisée par un capteur de position (6) qui est un capteur à effet Hall.
  8. Une machine à laver/sécher (1) selon l'une quelconque des revendications précédentes, caractérisée par un capteur de vibration (7) qui est un capteur piézoélectrique.
