Problems solved by technology

Therefore, in DE 102 25 335 B4 it is proposed to use oleohydraulic shock absorbers, which however generate very non-linear force components in the case of large loads and can only partially resolve the distortion of the measurement results question

Embodiment Construction

[0029] In this example, figure 1 The household appliance 1 shown in is a washing machine. The domestic appliance 1 comprises a washing liquid container 2 in which a washing tub 3 is rotatably mounted. In the washing tub 3 are located laundry items 4 which are washed in the domestic appliance 1 during a care process.

[0030] The washing liquid container 2 is suspended on the appliance housing 6 of the domestic appliance 1 by means of spring means 5 . In the present exemplary embodiment, the spring arrangement 5 comprises first and second springs 7 , 8 , wherein any number of said springs can in principle be arbitrary.

[0031] Furthermore, the rinsing liquid container 2 is supported on a damper arrangement 9 , which in the present exemplary embodiment comprises a first and a second damper 10 , 11 . The dampers 10 , 11 are in particular friction dampers. The number of dampers 10 , 11 used can in principle also be selected arbitrarily. For example, the damper arrangement 9 ...

Abstract

The invention relates to a method for determining a loading weight (B) of an oscillating system (16) of a domestic appliance (1) for treating items of laundry (4), in which method oscillations of the oscillating system (16) are damped against an appliance housing (6) of the domestic appliance (1) by means of at least one shock absorber (10, 11), and in which method measured values are provided by means of a displacement sensor (17), which measured values indicate a displacement of the oscillating system (16) with respect to a reference position, and the determination of the loading weight (B) takes place by means of a control device (14) using the measured values, wherein a temporal sequence of the measured values is evaluated by the control device (14) during a loading operation of the oscillating system (16) and slipping of the shock absorber (10, 11) during loading of the oscillating system (16) is detected using the temporal sequence, wherein a change value (24), caused by the slipping, of the displacement is determined by the control device (14) and is compensated for in the determination of the loading weight (B).

Description

technical field [0001] The invention relates to a method for determining the load weight of a vibration system of a household appliance for laundry care, in which method the vibrations of the vibration system are relative to an appliance of the household appliance by means of at least one vibration damper The housing is damped, in which method a measurement value is provided by means of a travel sensor, said measurement value represents the displacement of the vibration system relative to a reference position, and by means of a control device all the Determination of the loading weight mentioned above. Furthermore, the invention relates to a domestic appliance for laundry care, which is designed to carry out such a method. Background technique [0002] In domestic appliances for laundry care, such as in particular washing machines, the movement of the washing liquid container relative to the appliance housing is usually detected. If a movement of the washing liquid contain...
