Abstract
Необходимо определять дисбаланс барабана 3 стиральной машины 1 во время процесса отжима. Разработан способ, согласно которому барабан 3 стиральной машины приводится от приводного электродвигателя 5. На фазные обмотки 7, 8, 9 статора приводного электродвигателя 5 подается соответствующее электрическое переменное напряжение U, U, U, которое производится при помощи инвертора 26 из постоянного напряжения Uпромежуточного контура постоянного тока. По меньшей мере в одной из фазных обмоток 7, 8, 9 измеряется фазный ток I, I, I. Кроме того, еще до начала процесса отжима определяется начальная загрузка барабана стиральной машины и/или суммарная энергия, поданная на приводной электродвигатель во время, в частности, с начала процесса стирки, предшествующего процессу отжима. Дисбаланс определяется на основании измеренных значений этого фазного тока I, I, I, начальной загрузки и/или суммарной энергии за период процесса стирки. В частности, может быть построена кривая зависимости электрической энергии Е, поданной на приводной электродвигатель 5 с начала процесса отжима, от времени t, а повышение ΔЕ/Δt этой кривой V, Vможет лежать в основе определения дисбаланса. Кроме того, разработано соответствующее приводное устройство 2 и стиральная машина 1.It is necessary to determine the imbalance of the drum 3 of the washing machine 1 during the spin process. A method has been developed according to which the drum 3 of the washing machine is driven from the drive motor 5. The corresponding electric alternating voltage U, U, U is supplied to the phase windings 7, 8, 9 of the stator of the drive motor 5, which is produced by an inverter 26 from a constant voltage U of an intermediate DC circuit current. At least one of the phase windings 7, 8, 9 measures the phase current I, I, I. In addition, before the start of the spinning process, the initial loading of the washing machine drum and / or the total energy supplied to the drive motor during in particular, from the beginning of the washing process prior to the spinning process. The imbalance is determined based on the measured values of this phase current I, I, I, initial load and / or total energy for the period of the washing process. In particular, a curve of the dependence of the electric energy E supplied to the drive motor 5 from the beginning of the spin process on time t can be plotted, and the increase ΔЕ / Δt of this curve V, V can underlie the determination of the imbalance. In addition, a corresponding drive unit 2 and a washing machine 1 have been developed.
