Household appliance, in particular a washing machine having a stationary detergent tank

Abstract

The invention relates to a household appliance (6) having a rotating component (17) and a drive motor (20) for driving the component (17), said motor comprising a stator (21) having a first magnet arrangement (25) and a rotor (19) coupled to the component (17) and having a second magnet arrangement (24), and having a control device (34) for actuating the drive motor (20), wherein the rotor (19) can be rotated relative to the stator (21) about a rotary axis (S) by the interaction of the magnetic fields generated by the magnet arrangements (24, 25). According to the invention, the magnet arrangements (24, 25) are spaced apart from each other along the rotary axis (S), so that an axial gap (22) is formed between the magnet arrangements (24, 25). The control device (34) is further designed for achieving a coaxial arrangement of the rotor (19) with respect to the stator (21), such that when a distribution of the magnetic field generated by the first and / or the second magnet arrangement (24, 25) is controlled, a constant component of said magnetic field greater than zero is generated. The invention further relates to a method for operating a household appliance (6).

Description

technical field [0001] The invention relates to a household appliance having a rotatable component and a drive motor for driving the component and a control device for actuating the drive motor. The drive motor includes a stator having a first magnet arrangement and a rotor connected to the member and having a second magnet arrangement. The rotor can rotate relative to the stator in particular by the interaction of the magnetic fields produced by the magnet arrangement. The invention also relates to a method for operating a domestic appliance. Background technique [0002] The present invention preferably relates to a washing machine having a washing liquid tub fixedly connected to the housing. Such a washing machine is known, for example, from the publication EP 1 433 890 A2. In such a washing machine, the washing liquid tub or tub may be implemented in an increased size as compared with a conventional washing machine. The washer fluid tub is rigidly coupled to the hous...

AI Technical Summary

Problems solved by technology

[0003] In the subject matter according to publication EP 1 433 890 A2, there is the following disadvantage: When the laundry drum is loaded with laundry, the laundry drum is lowered relative to the washing liquid tub, thereby reducing the gap between the laundry drum and the bottom of the washing liquid tub

This increases water consumption and energy consumption

Moreover, if such a situation that the laundry drum is lowered relative to the washing liquid tub occurs, the laundry can more easily enter the gap between the laundry drum and the door collar provided near the loading opening of the laundry drum, which is increased due to the lowering of the drum. , which will be subjected to mechanical stress
