Definitions

  • the present invention relates to an operating device for an electrical device having a mounted on an opening of an outer wall of the device, about an axis substantially parallel to the outer wall rotating actuator body, and at least one sensor for sensing a position and / or rotational movement of the actuating body, and a by moving the actuator in a direction substantially perpendicular to the outer wall direction switch.
  • the actuator body In most rotary actuator operating devices, the actuator body is rotatable about an axis substantially perpendicular to the outer wall to which it is mounted. A peripheral surface of the actuating body is exposed over its entire length. This makes it possible to provide in the outer wall a relatively small, completely hidden by the actuating body opening through which extends a rotation of the actuating body to a sensor disposed inside the sensor transmitting shaft. By obscuring the opening of the actuator, the interior of the device is protected against the ingress of contaminants.
  • an intermediate wall is provided on the operating device, which separates the switch from the actuating body, and on the other hand, this intermediate wall can be deformed in at least one subregion by the displacement of the actuating body in order to transfer the movement of the actuating body to the To enable switch.
  • the intermediate wall is preferably sealed to the outer wall to protect not only the switch itself, but the entire interior of the device from contamination.
  • the intermediate wall expediently forms a shell whose concave side faces the opening of the outer wall and in which the adjusting body is accommodated.
  • the deformable portion of the intermediate wall can then be formed in a remote from the opening bottom portion of the shell.
  • the deformable portion preferably protrudes into the interior of the shell.
  • an axle bearing in which the adjusting body is rotatably supported, preferably with respect to the shell is elastically movable.
  • the intermediate wall forms a shell whose concave side faces the opening of the outer wall and in which the adjusting body is received, and the deformable region is formed by an edge of the shell.
  • the entire interior of the shell can be moved together with the actuator to operate the switch.
  • FIG. 1 shows a schematic section through an operating device according to the invention along a plane perpendicular to the axis of rotation of the actuating body
  • FIG. 2 shows a schematic section through the operating device along a plane parallel to the axis of rotation and perpendicular to the outer wall of the housing;
  • Fig. 1 shows a section through an inventive control element according to a first embodiment of the invention.
  • an outer wall 1 of an electrical device such as a cooker, a washing machine, dishwasher or the like
  • a rectangular window 2 is cut, which is backed by a shell 3 of substantially semi-cylindrical shape.
  • a control body 4 of cylindrical or, as shown here, polygonal prismatic shape and rotatably held about a plane perpendicular to the sectional plane of Figure 1 rotation axis.
  • a frame 5 inserted from the outside into the window 2 prevents the actuating body 4 from falling out of the shell 3 and fixes its axis of rotation 6.
  • a suitable sensor features On a front side of the adjusting body 4 are non-contact detectable by a suitable sensor features, in the present case by a magnetic field sensor such as a Hall sensor detectable permanent magnets 7, arranged in a predetermined pattern.

  • an opening is formed, in which a protruding into the interior of the shell 3 flexible membrane 8 is arranged and connected tightly with the shell 3.
  • a microswitch 9 At the side facing away from the actuator body 4 of the membrane 8, a microswitch 9 is arranged. A displaceable operating portion of the microswitch 9 engages in the rear concavity of the membrane 8.
  • Fig. 2 shows a section through the control element according to the invention in a plane containing the axis of rotation 6 of the actuating body 4, wherein the actuating body 4 itself is shown in plan view.
  • axle journals 10 of the adjusting body 4 are accommodated in short, horizontal grooves 11 on end faces 12 of the semi-cylindrical shell 3.
  • Springs 13 keep the axle 10 pressed against the frame 5.
  • the actuating body 4 is rotatable by a user, and a rotation is detected by means of a Hall sensor 14, on which the permanent magnets 7 pass during rotation of the actuating body.
  • a per se known, preferably alphanumeric display can be provided in order to display the operating mode selected by the control electronics to a user. If the displayed operating mode corresponds to a mode desired by the user in which the device is to operate, this confirms the selection by pushing the actuator 4 into the shell 3.
  • the springs 13 are elastically compressed, and the actuator urges the membrane 8 back until it abuts against the microswitch 9 and the latter is actuated.
  • the control circuit detects the actuation of the microswitch 9 and then activates the selected operating state.
  • the outer wall 1 can be moist without concern for electrical safety be wiped, and even if large amounts of liquid flow down her, for example, because on a kitchen stove in which the operating device is installed, a pot overcooked and run down liquid on the outer wall 1, the operating device can be operated without hesitation. Liquid or other impurities that actually get into the shell 3, can be easily removed by the frame 5 dissolved, the actuator body 4 removed from the shell 3 and this is wiped.
  • another, not shown in Fig. 2 Hall sensor on the front side 12 of the shell 3 may be mounted at a distance from the Hall sensor 14, the distance from the magnets 7 with each other or a multiple of this distance is different.
  • the distance of the Hall sensors measured from each other along the circumference of a centered on the axis of rotation of the actuating body 4 circle is n + 1/2 times the distance of the alternately poled permanent magnets 7, where n is a natural number, so that depending on the direction of rotation the adjusting body 4 different phase shifts between the output signals of the two sensors are obtained, which allow the control circuit to detect the direction of rotation of the actuating body and to take into account in the selection of an operating state.
  • the Hall sensors are replaced by optical sensors with a photodetector and a light source
  • the shell 3 is translucent at least where necessary to pass a scanning light beam from the light source to the photodetector
  • Light source and photodetector can be arranged on opposite end faces 12 of the shell 3
  • the actuator body 4 has alternately opaque and translucent sections, for example in the form of axial bores or grooves formed on its peripheral surface, via the light from the light source to the photodetector depending on Rotate position of the actuator 4 reach or can not get.
  • an end face of the adjusting body 4 may be formed alternately reflective and non-reflective, and light source and light sensor are arranged on the same end face 12 of the shell 3.
  • Another possibility is to arrange a plurality of optical sensors staggered in the radial direction on a front side 12 of the shell 3, which in each case opposite concentric zones on an end face of the actuating body 4, which have different distributions of the reflectivity. These distributions may correspond in particular to a Gray coding.
  • FIG. 3 shows, in a section analogous to FIG. 1, an operating device according to a further embodiment of the invention.
  • This embodiment differs from that of FIG. 1 and its modifications described above in that the shell 3 is connected to the outer wall 1 via an expandable section shown here as a bellows 15.
  • the actuator body 4 inside the apparatus When a user presses the actuator body 4 inside the apparatus to confirm an operating state selection, the stretchable portion 15 expands while the remainder of the cup remains substantially undeformed.
  • the side of the shell 3 facing away from the window 2 thus actuates the microswitch 9, whereby the selection is confirmed and the control electronics are made to activate the selected operating state.
