Definitions

  • the present invention relates to a method for operating a domestic appliance for the care of laundry, in which prior to a transition to a spin operation in a laundry distribution operation, a distribution of the laundry items in an interior of a drum of the household appliance by increasing and / or decreasing a rotational speed of the drum is made ,
  • Washing machines usually have an electronically controlled drive. Before a transition to a so-called spin operation, a drum is accelerated over a fixed slow laundry distribution phase or a laundry distribution operation and an unbalance is estimated. In this case, the estimation of the imbalance usually takes place via an engine speed or a loading of the drum or via a power. It is always possible to cancel the spin mode or to influence the further spin cycle.
  • methods are known from the prior art in many ways, which are used for measuring and then to reduce the imbalance or to control the spinning operation. For example, the document discloses DE 197 53 382 A1 a method for distributing the laundry items in a drum of a washing machine.
  • the distribution of the laundry items is performed by controlling the spin operation of the washing machine, wherein first the position of the imbalance of the drum is determined. The determination of the position of the imbalance can take place at a laundry installation speed. Subsequently, the drum is accelerated or braked depending on the detected position of the unbalance of the drum, so that the laundry items in the drum is redistributed during this acceleration or braking.

  • the drum of the washing machine rotates at a very high speed, for example, at a speed of 1,200 rev / min, so that the laundry items can rest firmly against an inner wall of the drum. If the items of laundry are distributed unevenly on the inner wall of the drum, then there is an imbalance, wherein the drum and the mechanically connected to the drum parts of the washing machine, in particular a tub or a motor to begin to oscillate.
  • These vibrations can be relatively strong, especially in the resonance ranges of the machine, so that the drum can not be raised to the target speed, which in turn can lead to unsatisfactory spin results.
  • the distribution of the items of laundry can be influenced in a range of a laundry installation speed by specifically increasing or decreasing the rotational speed of the drum.
  • the laundry installation speed is understood to mean a speed at which a centrifugal force acting on the laundry items becomes greater than the gravitational force.
  • the speed at which the items of laundry attach to the inner wall of the drum depends strongly on the loading of the drum. By a suitable choice of the speed can thus be targeted a certain proportion of the laundry to be solved, with the laundry then randomly redistribute at the next increase in speed.
  • the distribution of the laundry items can therefore be influenced by selectively increasing or decreasing the speed as a function of the position of the imbalance relative to one revolution of the drum.
  • the distribution of the laundry items can already be determined during the washing or rinsing phase and optionally influenced.
  • a method of operating a washing machine with an improved spin cycle is off EP 1 609 901 A1 known.
  • the laundry drum is accelerated to a speed at which laundry in the drum of the washing machine rests against the drum wall, and during this step determines the static imbalance and a so-called lifting torque, which is required not to the Drum wall to raise adjacent laundry.
  • This lifting torque indicates what percentage of the laundry rests against the drum wall.
  • the actual spin is initiated when the static imbalance and the lift torque are less than a limit associated with sizes. If at least one size exceeds its limit, depending on the static unbalance and the lifting torque, the rotational speed of the drum is lowered or increased and the measurement of the static imbalance and the lifting torque is repeated.

This period is compared with the amplitude A of the determined Fourier coefficients K F. As shown, the higher-frequency components of the course of the deflection signal W are significantly larger, which is directly attributable to falling laundry items 17 in the drum 2.

  • the second and sixth Fourier coefficients K F2 , K F6 have a significantly higher amplitude A than the remaining Fourier coefficients K F.
  • higher-frequency components of the deflection signal W are clearly recognizable. Because of its Fourier coefficients K F, it can now be established that the stability S of the distribution of the laundry items 17 or the degree of contact of the laundry items 17 on the inner wall of the drum 2 is very small.
  • the deflection signal W for the calculation of the fast Fourier transformation should correspond exactly to one drum revolution or one period. If this is not the case, for example, if the data record is too long, the Fourier coefficients K F are smeared out. Such a case is in Fig. 13 shown.
