Definitions

  • the invention relates to a method for controlling the spinning process of a drum washing machine according to the preamble of claim 1 (DE-OS 34 16 639).
  • the indoor unit with suds container, laundry drum and drive unit of a drum washing machine is a damped, oscillatory system and has resonance phenomena in certain speed ranges of the laundry drum in the event of unbalance in the drum. These resonance phenomena are expressed in an increase in the vibration amplitude of the indoor unit.
  • the indoor unit may stop or the washing machine may be offset when driving through the critical speed ranges.
  • the laundry drum is accelerated from a washing speed by a gradual increase in speed to a spin speed.
  • the laundry drum then goes through the so-called laundry distribution phase, in which the laundry items are distributed as evenly as possible on the drum jacket until the laundry application speed (n A ) is reached.
  • the speed or current consumption behavior of the electric motor is evaluated by the device for measuring the unbalance.
  • the laundry drum is then accelerated from the laundry application speed to the final spin speed, the critical speed range being passed quickly with a defined speed increase.
  • DE-OS 33 29 421 discloses a method for operating a washer-extractor with an inner drum divided into chambers, the transition from a washing speed to a centrifugal speed always taking place from a specific position of the inner drum which is predetermined by the construction of the inner drum . In such a washer-extractor, there is an uneven distribution of laundry on the drum circumference due to the drum division, which leads to high imbalances.
  • the method described in DE-OS 33 29 421 is intended to provide an approximately congruent and rotationally symmetrical laundry distribution in the chambers of the inner drums in order to avoid high unbalance.
  • the disadvantage here is that the position from which the run-up for spinning takes place is predetermined by the design of the drum.
  • the object of the present invention is therefore to avoid the disadvantages described and to develop a suitable method for controlling the spinning process of a drum washing machine, in which the drum can also be spun with an impermissibly high imbalance.
  • This object is achieved by the features of claim 1.
  • Expedient refinements and developments of the invention result from the following claims.
  • the advantages that can be achieved with the invention are, in particular, that the deflection of the vibrating unit caused by the unbalance is reduced by the method for controlling the spinning process. As a result, the machine does not shift even at high spin speeds. Likewise, the oscillatingly suspended indoor unit no longer strikes the housing of the machine. In today's washing machines, it is common to increase the inertial mass of the vibrating unit so as to reduce the amplitude of the vibratable system. In contrast, in washing machines with the method according to the invention for controlling the spinning process, the additional masses on the tub can be reduced. This saves material and manufacturing costs.
  • a drum washing machine with an oscillatingly suspended indoor unit (1) and with a microcomputer control (2) and a device for detecting the unbalance (3) is shown schematically.
  • the laundry drum (5) is rotatably mounted in the tub (4) and is driven by the electric motor (6).
  • the fluctuations in the speed, the motor current consumption and / or the torque can be evaluated as an indication of a possible unbalance.
  • the tachometer generator (7) connected to the motor shaft generates a voltage or signals corresponding to the respective speed of the laundry drum.
  • the control variable for the triac (8) or the device for motor current control e.g. the actual voltage generated by the tachometer generator (7) is compared in a known manner with a target voltage (reference voltage) corresponding to the desired speed.
  • the triac is ignited or locked (8).
  • the laundry drum (5) passes through a laundry distribution speed range (t V ) when accelerating from a washing speed (n W ).
  • this distribution speed range the laundry is distributed well around the drum circumference, so that better drainage of the laundry and the least possible imbalance is achieved.
  • a laundry application speed range can follow the laundry distribution speed range (t V ) (t A ) with constant drum speed (n A ).
  • Any imbalance that may be present is sensed by the electronics of the washing machine in the distribution speed range and / or in the laundry supply speed range.
  • the size and the position of the unbalance are sensed by evaluating the fluctuations in the speed, the motor current and the torque in relation to the motor control.
  • the size of the change in speed is a measure of the size of the unbalance.
  • the speed, the motor current consumption and the torque provide information about the position of the unbalance in the drum.
  • the measured values such as the size and position of the imbalance are evaluated by the microcomputer control (2) as control variables for the triac (8) or the device for motor current control.
  • the measured values are evaluated on the basis of knowledge of the vibration behavior of the indoor unit (1).
  • the indoor unit (1) of the drum washing machine is a damped, oscillatory system, the deflection of which, at speeds above the critical speed (resonance speed), assumes a phase shift of 180 ° with increasing speed for excitation-related excitation.
  • the amplitudes assume a constant, unbalance-dependent value above the critical speed range; Excitation and deflection of the laundry drum almost cancel each other out due to the phase shift.
  • the system capable of oscillation takes a certain time to settle, ie until a constant oscillation amplitude of the indoor unit occurs. If the critical speed range can be passed quickly in a known manner, it has sluggish system no time to reach the high amplitudes typical for the critical speeds with corresponding excitation due to unbalance. The deflection thus lags behind the suggestion.
  • the method according to the invention is based on this knowledge insofar as the position of the unbalance sensed by the device for measuring the unbalance (3) is decisive for the point in time of the speed-increasing activation of the electric motor.
  • the acceleration value for the run-up for spinning can be reduced in an advantageous development of the invention. Adjusting the acceleration to the size of the unbalance has the advantage that the electric motor is only heavily loaded in the relatively rare cases of high unbalance formation.
  • a further possibility for reducing the amplitude of the oscillating indoor unit (1) would be to use the determined position and the size of the unbalance for a corresponding acceleration of the laundry drum (5) when passing through the critical speed ranges depending on the angle of rotation of the drum.
  • the acceleration of the laundry drum (5) can be achieved in the course of a few drum revolutions when driving through the critical speed ranges by appropriate motor power control, for example the control of the triac (8), which also reduces the vibration amplitude of the indoor unit (1).
  • Corresponding acceleration is understood here to mean that, depending on requirements, the acceleration in the angular range from 60 ° to 170 ° (measured in the direction of rotation) is greater than zero, in the remaining angular range it approaches zero, is zero or can also become negative.
