Definitions

  • the invention relates to a method for controlling a spin cycle of a washing machine with a resiliently supported in a housing tub, in which a rotatable about a substantially horizontal axis drum is mounted, with a variable speed drive, which drives the drum, with a device for detecting a Movement of the tub, which is caused by non-uniformly distributed in the drum laundry items, and with a program control that controls the spin cycle, comprising the steps according to the preamble of claim 1.
  • the invention further relates to a washing machine for performing the method.
  • a method for compensating imbalances in a washing machine is in DE 33 42 376 A1 disclosed.
  • a drum rotatably mounted in the washing machine is accelerated to a first speed at which the laundry items located in the drum abut the drum shell, an imbalance during rotation of the drum measured at a speed greater than or equal to the first Speed is controlled, and the speed in response to the change in unbalance.
  • the washing machine has a device for detecting the liquor container movement, which is caused by non-uniformly distributed in the drum laundry, ie an imbalance of the laundry.
  • the known washing machine has a control device which can act on a drive of the washing machine, so that in the case of a heavily non-uniformly distributed laundry load, the spin speed reduced or even the spin process can be stopped.
  • a voltage proportional to the amplitude of the tub movement of the electro-mechanical transducer is detected a voltage proportional to the amplitude of the tub movement of the electro-mechanical transducer.
  • the movements caused by a laundry imbalance of the tub occur in particular from a rotational speed of the drum, in which the laundry items lie substantially fixed to the drum wall.
  • the method according to the invention for controlling a spin cycle is advantageously applicable to a washing machine comprising a tub supported resiliently in a housing with a drum rotatably mounted about a substantially horizontal axis, a variable speed drive driving the drum, means for detecting a movement of the tub, which is caused by non-uniformly distributed in the drum laundry items, and having a spin control controlling program control.
  • the method includes the steps of having the drum accelerate to a first speed at which the laundry substantially abuts the shell of the drum, a movement of the tub in at least one direction for at least a predetermined period of time during the rotation the drum at a speed which is greater than or equal to the first speed detected, and an amplitude of the movement for a speed, hereinafter also called the movement amplitude, determined or determined for the detected direction.
  • the method is characterized in that the change in the amplitude of movement over the rotational speed determined and detected during the predetermined period of time and determined movement amplitudes and the further spin cycle can be controlled in response to the change in the movement amplitude.
  • the speed during a detection of the movement can be determined particularly favorable from the control variables required for the speed control, for example, a detected instantaneous speed or a known setpoint speed of the drive or the drum.
  • the tub movements can be reliably maintained within acceptable limits, since even before reaching the still permissible amplitude of motion by influencing the spin cycle excessive movement of the tub can be counteracted.
  • stops of the tub to components of the washing machine during acceleration of the drum by a critical speed range in which the maximum movements can occur avoided. Displacement of the washing machine or damaging the same due to the stops can be reliably prevented.
  • a critical speed range is a range in which the drum is operated at a speed whose rotational frequency is close to a resonant frequency of the vibrating tub.
  • the movements are detected in a direction in which the largest tub movements are to be expected.
  • the change in the amplitude of movement over the rotational speed is determined by determining and storing the movement amplitudes in a first step for different rotational speeds, wherein the change in the movement amplitude over the rotational speed is then determined in a second step by means of the stored values. by calculating the slope of the amplitude of motion as a function of the speed.
  • Oscillating mounted tubs which together with rigidly attached to him components can be referred to as vibration systems, have for each possible direction of movement on the mechanical structure of the washing machine dependent vibration behavior.
  • oscillating systems have six degrees of freedom of movement, three translational and three rotational degrees of freedom.
  • Each degree of freedom has a specific degree of freedom for the degree of freedom that causes the vibration of the system to be increased when the vibrating system is excited at resonance, that is, the tub of the tub is rotated at a speed corresponding to the resonant frequency.
  • the resonance frequency and the degree of amplification are dependent on the masses or the inertias, the spring stiffnesses, the damping constants and the geometric structure of the oscillating system.
  • the movement of the tub in different directions in particular in mutually perpendicular directions X, Y and Z, detected.
  • the movements for each direction can be judged separately. It is advantageous that the vibration behavior for the detected degrees of freedom individually and in one direction for the movement of the tub available free space, which is limited by the housing and by internals in the housing, can be considered.
  • the movements in the individual directions can preferably be combined into a resulting movement.
  • the motion amplitude is then determined with respect to the resulting motion.
  • Such a configuration can advantageously provide a single control parameter which at the same time takes into account the influence of the movements of the tub in different directions.
  • the oscillating motion of the tub is primarily a sinusoidal vibration, therefore, it is advantageous to select the predetermined period of time for detecting the amplitude of motion such that the duration is at least greater than or equal to a period in which the drum can make at least half a turn ,
  • the maximum width of a positive or negative half-wave of a vibration within a a predetermined period of time or a predetermined measurement interval understood.
  • quantities are also understood as amplitude which are substantially proportional to the amplitude. Such quantities are, for example, a width between a maximum and a minimum value (peak-peak) of the oscillation, an effective value of the oscillation or an average amplitude of the oscillation within a measuring interval.
  • the change of the movement amplitude over the rotational speed is determined from at least two successive detections of the movement.
  • the change can be formed in a particularly simple manner, for example by forming the difference between the values of two consecutive detections, the sequence of a detection in each case being able to be identical.
  • the required storage means are in such an embodiment less than in a possible alternative embodiment in which the amplitudes and speeds are determined and stored in a first step for a certain speed range and stored in a second step by means of the stored values, the change of the amplitude of movement over the speed is determined.
  • the change in the amplitude of movement over the speed can be particularly easily formed from a difference quotient, i. the quotient is calculated from the difference between two movement amplitudes and the difference between the rotational speeds assigned to the movement amplitudes.
  • the quotient is calculated from the difference between two movement amplitudes and the difference between the rotational speeds assigned to the movement amplitudes.
  • the first derivative of the function of the speed-dependent movement amplitude is calculated.
  • a nutritional function of the amplitude of movement over the rotational speed can be determined, whose first derivative is known or easily determinable.
  • Such a nutritional function can be, for example, a polynomial.
  • the influencing of the spin cycle according to a further embodiment, according to which the change of the movement amplitude over the rotational speed is compared with a predetermined limit value of the change of the movement amplitude, can be realized particularly easily.
  • the limit value is predetermined in such a way that a drop below the limit value indicates that the rotational speed can be further increased, since with a further speed increase, in particular when the drum is rotated in the resonance range or when the drum is accelerated through the resonance range, the movements of the drum Lye container remain sufficiently small and will not rise above allowable limits.
  • a to be expected during the spin cycle motion amplitude of the tub can be extrapolated for a next possible drum speed from the currently determined course of the determined amplitude of motion above the speed.
  • many methods are known, for example, the trend of the instantaneous change of the movement amplitude can be continued.
  • the extrapolated amplitude of motion can be compared to a predetermined threshold.
  • such a comparison is also executed with the same effect by determining the limit value for the change in the movement amplitude as a function of the detected rotational speed and / or the detected amplitude of movement.
  • no extrapolation must be performed, but it is sufficient a simple comparison of the change in the motion amplitude with a dependent of the detected speed and / or the detected amplitude of motion limit.
  • the comparison can be carried out early at any speed.
  • the degree of a momentary change in the movement amplitude can be used as a measure of a momentary movement amplitude. In such a case, it is sufficient to form the limit value for the change in the movement amplitude only as a function of the rotational speed. It is preferably the already determined movement amplitude to take into account.
  • the limit value for the change of the movement amplitude can also be exclusively dependent on the momentary movement amplitude, the verification of the limit value takes place at a fixed predetermined speed.
  • the instantaneous amplitude of movement can also be determined on the basis of a detected laundry imbalance. Thus, for example, an evaluation of the rotational irregularity of the drum rotational speed caused by a laundry load unequally distributed in the drum can be used to determine the laundry imbalance. Such determined laundry imbalance is proportional to a perpendicular to the drum axis aligned movement amplitude of the tub.
  • the limit value for the change of the movement amplitude can also be formed as a function of the laundry imbalance.
  • the drum speed is reduced, in particular the spin cycle is interrupted, ie. the drum is set still.

  • a targeted change in the spring rate c and / or the damping value k of the support of the tub in particular a controllable damper, the resonance frequency of the oscillating system and thus the vibration behavior can be changed. Therefore, it is possible to influence the movement of the vibration system in such a way that set at the other speeds of a current spin cycle significantly reduced motion amplitudes of the vibration system.

  • a plurality of limit values of the change in the movement amplitude or the extrapolated movement amplitude are provided, wherein the control measure to be initiated depends on which limit value is exceeded.

  • a force acting on the tub can be advantageously generated by a variation of the spin rate and / or the drive torque, so that the movement amplitudes of the tub are reduced in the further spin cycle.
  • Exceeding the limit value can also indicate that the motion amplitudes still remain sufficiently small, despite a relatively high laundry imbalance, when a resonance is passed through quickly. That is, when the limit is exceeded, a large rate of spin, and preferably a reduced maximum drum speed, is set. Preferably, in such an embodiment, a maximum limit value is monitored, which still has to be undershot despite everything.
