- the curve represented by the information can for example also be evaluated such that z.
- the degree of filling eg in%) is determined.
- the curve shown in Fig. 10 was determined based on a treatment space formed as a drum with a maximum possible load capacity of 6 kg load with 2 kg load in a main wash of a cleaning program at about 50 to 55 U / min.
- the cleaning program was carried out by a household appliance designed as a washing machine (eg household appliance 300 according to FIG.
