Definitions

  • the present invention relates to an operating device for an electrical device having a control element rotatably mounted on an opening of a housing wall of the device about a housing wall substantially parallel to the housing wall extending axis extending on an inner side of the housing wall and a sensor for detecting a rotation and / or orientation of the adjusting body.
  • actuator bodies in the form of rotary knobs which are mounted on a shaft passed through the housing wall for transmitting rotation to a sensor mounted within the housing. Since the adjusting body is located completely outside the housing, there is no undue risk that solid or liquid contaminants adhering to the actuating body as a result of the rotation pass into the interior of the device.
  • the object of the invention is therefore to develop the known control device so that it is suitable for use on household appliances such as a kitchen stove, a dishwasher, a washing machine or the like, in particular so that the actuating body can be cleaned easily and without risk of contamination of the device interior.
  • the object is achieved by releasably mounting in the opening of the housing wall an insert member which partially obstructs the opening, and in that the opening is dimensioned to permit removal of the actuator body through the opening when the insert member is not mounted in the opening , So can be removed by removing the insert of the actuator and cleaned separately from the device. To be cleaned surfaces of the actuator are easily accessible.
  • To the opening of the housing wall preferably includes a shell, in which the adjusting body is received.
  • a tray prevents contaminants passing through the opening into the housing interior from spreading; instead, when the actuator is removed, they can be conveniently removed from the shell.
  • the shell preferably has a groove on two end faces, which receives a journal of the actuating body and has a longitudinal end which opens onto the opening.
  • the insert preferably has engaging in the shell, the journals touching projections. These projections can engage in the groove from said longitudinal end; Alternatively, they can each engage between an end face of the shell and one of these facing end face of the actuating body touching the axle journal.
  • the operating device preferably comprises a switch which can be actuated by displacement of the adjusting body.
  • a spring element is preferably provided, which exerts a displacement of the opposite restoring force on the actuating body.
  • the spring element can be added to save space in the groove.
  • the spring element expediently engages on the one hand on the shell or the housing wall and on the other hand on the adjusting body. If, however, the shell is displaceable with the adjusting body, the spring element expediently engages on the one hand on the shell and on the other hand on the housing wall.
  • the insert is preferably formed as a window bounding frame.
  • Fig. 1 is an exploded view of an operating device according to the invention
  • FIG. 2 shows a section through the operating device along a plane containing the axis of rotation of the adjusting body.
  • FIG. 3 shows a section analogous to FIG. 2 according to a further developed embodiment of the invention
  • FIG. 4 shows a section through a further embodiment of the operating device along a plane perpendicular to the axis of rotation of the actuating body
  • Fig. 5 is a view similar to Figure 4 representation in which the actuator is omitted.
  • FIG. 6 is a perspective view of a frame of the operating device; and FIG. 7 shows a section analogous to FIG. 3 through an operating device with the frame shown in FIG. 6.
  • a section of a housing wall of an electrical appliance such as a cooker, a dishwasher, a washing machine or the like is designated 1.
  • an opening 2 is cut, the shape and dimensions are set so that a control body 4, the opening 2 can happen.
  • the actuating body 4 here has the shape of a regular 12-sided prism with an axis of symmetry 6 and with end faces 16, from each of which a journal 10 protrudes.
  • a shell 3 is fixed, for example by gluing a peripheral edge web 21 of the shell 3 on the inside of the housing wall 1.
  • the integrally molded plastic shell 3 has substantially the shape of a half cylinder with a peripheral wall 22 and two end walls 12. On each end wall 12 is a short, to the interior of the shell 3 open toward groove 1 1 is formed, which has a housing wall 1 towards the open longitudinal end 23.
  • the grooves 1 1 are provided to receive the journal 10 of the actuator 4. In each case, a closed rear end of each groove 1 1 forms part of a one of the journal 10 receiving sliding bearing in which the adjusting body 4 is rotatably mounted about the axis 6.
  • a sensor 14 for contactless detection of distributed at an end face of the adjusting body 4 in a regular pattern features is mounted on an outer side of the end wall 12.
  • the sensor 14 may, for. B. a Hall sensor or another magnetic field sensor, which scans a magnetic field of a mounted in the actuator body 4, rotatable with the actuator body 4 magnets or a distribution of ferromagnetic material in the actuator body, or it may be an optical sensor such as a reflection light barrier , which scans surface portions of the adjusting body 4 with different reflection properties.
  • An electronic control circuit is connected to the sensor 14 in order to select an operating state of the device, to which the housing wall 1 belongs, on the basis of an orientation or rotational movement of the adjusting element 4 detected by the sensor 14.
  • a frame 5 is provided to secure the actuator 4 in the shell 3.
  • the frame 5 defines a window 7 through which the actuator 4 is accessible to a user to be turned, but too small to let the actuator 4 pass. More specifically, the height of the window 7 is smaller than the diameter of the actuator 4, and the frame 5 covers the longitudinal ends 23 of the grooves 1 first
  • the frame 5 has on its housing wall 1 facing back two pins 24 which engage in the assembled state in the grooves 1 1 and complete the journal 10 receiving bearings.
  • the pins 24 carry at their side facing away from the actuator body 4 sides each have a locking projection 25 which engages behind the edge of the opening 2 and so the frame 5 is locked to the housing wall 1.
  • the locking projection 25 has two at an acute angle to the insertion direction of the frame oriented oblique edges 26, 27, which allow insertion of the frame 5 in the opening 2 and pulling out of the frame 5, respectively, overcoming an appropriately selected deformation resistance.
  • the frame 5 can be removed and the adjusting body 4 removed, in order to clean it and, if necessary, the interior of the shell 3.
  • Fig. 3 shows a further developed embodiment of the operating element.
  • each compression springs 13 are received in the grooves 1 1, which hold the journal 10 of the actuator against the pin 24 of the frame. By overcoming the force of the compression springs 13, it is possible to push the adjusting body 4 deeper into the shell 3.
  • an opening is formed in which a projecting into the interior of the shell 3 flexible membrane 8 is arranged and connected tightly with the shell 3.
  • a microswitch 9 is arranged at the side facing away from the actuator body 4 of the membrane 8. A displaceable operating portion of the microswitch 9 engages in the rear concavity of the membrane 8.
  • the actuator body 4 When a user presses the actuator body 4 against the force of the springs 13 in the shell, the actuator body 4 comes into contact with the membrane 8 and urges them back, whereby finally the microswitch 9 is actuated.
  • An actuation signal of the microswitch 9 is used by the control circuit as an acknowledgment of a previously selected operating state, that is, the previously selected operating state is activated after receiving the confirmation.
  • the senor 14 and a regular distribution of features sampled by it can also be arranged on the peripheral wall 22 of the shell or the lateral surface of the setting body 4.
