Abstract
The invention relates to a rotary selector as display console for contact-free on and off switching as well as for switching of the automatic control of a number of different cycles of electrically operated domestic appliances, such as washing machines, dryers, dishwashers or comparable units.
To simplify its assembly and maintenance the inventive rotary selector (1) has mutually communicating catch devices and a plate arranged at a distance thereto with a rotary field sensor according to Hall technology, whereby spring-loaded ball lockings enable defined and switchable rotation of an operating element (2) with magnetic device in ranges up to 360°, and whereby angle-dependent variables for control of a wide range of cycles are generated ih a known manner in the rotary field sensor.

15. A rotary selector as display console for contact-free on and off switching and for automatic control of a number of different cycles of an electrically operated device, the selector comprising:
-
a rotatable operating element having a magnetic device axially arranged on the operating element;
a panel comprising a guide component including a fixable plate and a magnetic rotary field sensor connected to the fixable plate, the operating element being axially received by the guide component;
the operating element having retaining pegs engaging the guide component;
at least one of the guide component and the operating element having a catch element, and the other having a locking contour, the catch element engaging the locking contour and forming multiple defined steps as the operating element rotates with respect to the guide component; and
the magnetic device being disposed a distance from the rotary field sensor and being rotatably movable in a defined step-wise manner with respect to the rotary field sensor, the rotation of the magnetic device corresponding to the operation of the rotary field sensor. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 33)

34. A washing machine comprising:
-
a housing;
a drum at least partially disposed within the housing and mounted for rotation with respect to the housing;
a control unit controlling the on and off switching and the automatic control of multiple operational cycles of the washing machine;
a rotatable operating element having a magnetic device axially arranged on the operating element;
a panel supported by the housing and comprising a recess forming a depression and a cylindrical guide component connected to the recess with at least one annular leg, the operating element being axially received by the guide component and having retaining pegs engaging an annular surface of the guide component, the operating element having a catch element and the guide component having a locking contour, the catch element engaging the locking contour and forming multiple defined steps as the operating element rotates with respect to the guide component;
a fixable plate connected to the guide component and having a magnetic rotary field sensor connected to the fixable plate, the magnetic device being disposed a distance from the rotary field sensor and being rotatably movable in a defined step-wise manner with respect to the rotary field sensor;
the magnetic device being coupled via its magnetic field to the magnetic rotary field sensor in non-contacting Hall sensor technology, the rotary field sensor sensing the position of the magnetic device with respect to the rotary field sensor; and
an interface integrated into the rotary field sensor and sending a signal to the control unit representing the position of the magnetic device with respect to the rotary field sensor, the signal corresponding to one of the multiple operational cycles of the washing machine.
