Laundry Washing Machine with an Electronic Device for Sensing the Motion of the Wash Assembly Due To the Dynamic Unbalance of the Wash Laundry Drum Assembly, And Relative Operating Method

摘要

A method of sensing the motion of the wash assembly (3) of a washing machine (1) due to the dynamic unbalance of the laundry drum assembly (6), and which comprises the steps of: increasing the rotation speed (ω) of a laundry drum (6) to a first rotation speed (ωDIST); determining a first parameter (TFRICTION; AHFREF) related to the time pattern of the values of an unbalance function A=T−Jdω/dt; increasing the rotation speed (ω) of the laundry drum (6) by a predetermined value (Δω) determining, at each increase (Δω) in rotation speed (ω), a second parameter (ALF; AHF) related to the time pattern of the values of the unbalance function A=T−Jdω/dt filtered at the predetermined filtration frequency (LF; HF); calculating the difference (TdynLF; TdynHF) between the second parameter (ALF; AHF) and to the first parameter (TFRICTION; AHFREF).
