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 co

Embodiment Construction

[0034] Figure 1A and 1B Both show a drive motor 1 known from the prior art. The drive motor 1 is a brushless DC motor or a permanent magnet excitation synchronous motor. The drive motor 1 includes a stator 2 and a rotor 3 . The stator 2 and the rotor 3 are arranged coaxially with each other, and the rotor 3 is located within the stator 2 , ie the stator 2 surrounds the rotor 3 . The rotor 3 has permanent magnets 4 which are arranged in alternating polarity in the circumferential direction on the radially outer surface of the rotor 3 . The stator 2 has electromagnets 5 on its radial inner side, which are formed by a winding with a plurality of phase legs, for example with three phase legs.

[0035] If such a drive motor 1 is used in a washing machine at this time, as is known from the publication EP 1 433 890 A2, the following problem arises to a certain extent: the laundry drum of the washing machine can be lowered relative to the stationary washing liquid tub . This cre...

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...
