Method for determining a mass of laundry items in a household appliance for the care of laundry items by a non-continuous movement of the laundry drum, measuring device and household appliance

摘要

The invention relates to a method for determining a mass of laundry items (14) in a household appliance (1) for maintaining laundry items, in which the mass of the laundry items (14) within a laundry drum (3) of an oscillating system (8) of the household appliance (1) is determined, wherein a vibration of the vibration system (8) is generated by excitation of the vibration system (8) by means of a drive motor (7) for rotating the laundry drum (3), the vibration of the vibration system (8) is detected by means of a sensor device (11) and by means of an evaluation device (12) the mass of the laundry items (14) is determined on the basis of the detected vibration, the vibration system (8) being excited in chronologically successive excitation steps (16), with the laundry drum (3) during each of the excitation steps (16) is accelerated by means of the drive motor (7), and the vibration of the oscillation system (8) is detected wi during the acceleration of the laundry drum (3) approx.
