Definitions

  • the invention relates to a device for determining the unbalance of a loaded drum in a washing machine with a swinging suds container in which the Drum rotatably supported and driven by a motor.
  • the Invention a method for determining the unbalance in such a washing machine.
  • the invention also relates to a method for controlling the spinning process such a washing machine.
  • a washing machine with a level sensor which consists of a riser arranged in the drain area of the tub and connected to it Pressure measuring device exists.
  • the invention presents the problem of an apparatus and a method for determination to disclose the imbalance of the type mentioned at the outset, which is simple and can be used in a wide range of speeds. It turns out in particular the invention the problem, a method for controlling the spinning process Washing machine using a device for determining the unbalance of the input mentioned type, taking into account the drainage of unbalance becomes.
  • the drum (1) is rotatably mounted in the tub (2) in a known manner. It is through a motor (3) driven.
  • FIG. 2 shows an enlarged view of a riser (6) in which two weighted Membranes (13a, b) are arranged. These have the choice of certain weights (14) and / or spring constants of the membrane (13) natural frequencies that are different Speed ranges are matched.
  • a high-resolution pressure sensor (7) preferably an analog one, must be used as the pressure sensor (7)
  • Pressure sensor (7) can be used to detect the dynamic signal components. This means both the water level and the deflection of the tub due to unbalance (2) can be sensed, the program control (10) must separate the quasi-static and the dynamic signal component. For this reason a microprocessor control (10) is preferably used as the control device.
  • FIG. 3 shows a speed-time diagram to explain a method for controlling the spinning process.
  • the drum (1) is first accelerated from the washing speed n W (approx. 50 rpm) to a first measuring speed n 1 ( ⁇ 100 rpm) below the resonance speed n R (300-500 rpm).
  • the laundry must lie against the drum jacket at this speed (n 1 ), so that any imbalances have already formed.
  • the unbalance is determined by the microprocessor control (10). This can advantageously be done by the method described above.
  • the drum (1) is further accelerated to a second measuring speed n 2 (800 rpm) above the resonance speed n R (-). Since the unbalance is checked again here, the unbalance limit can be set significantly higher than in the known single-stage unbalance determination method.
  • the microprocessor control (10) brakes the drum (1) to such an extent that the contact speed n A is undershot and the laundry can be redistributed. Then a new spin starts (• - • - •).
  • the above-described method can reduce the unbalance at any time be taken into account by drainage during spin-up.
