Definitions

  • the invention relates to an actuating device with a printed circuit board and with a device-fixed rotary member.
  • the actuating device is particularly suitable for operating a household appliance.
  • Such an actuator is used for example in a control panel of a household appliance, such as a washing machine, a dryer, a dishwasher, a refrigerator or a stove.
  • a control panel is increasingly the design in the foreground, in particular, represent a different positioning of the controls and their design important design elements. Since the controls are assigned to the arranged on the circuit board switching elements, each different positioning or design of the controls requires the development of a separate circuit layout for the circuit board. However, this is associated with a high development effort and therefore unprofitable.
  • an actuating device in particular for a household appliance, with a printed circuit board and a device-fixed rotary member, wherein on the circuit board, a mechanically actuated switching element is arranged, and wherein the means for mechanical actuation of the switching element are included in a rotation of the rotary member ,
  • the invention is based on the fact that design requirements for a specific embodiment of a control panel of a household appliance not only affect the positioning of the controls but also their geometric design itself.
  • specific designs are often different in that once a rotary element or rotary switch and the other time a push or push switch is desired for operation. For this purpose, different switching elements are to be placed on the circuit board.
  • the invention is based on the consideration of equipping the printed circuit board generally with a mechanically operable switching element which then actuated by both a rotary member and a pushbutton.
  • the invention provides for a solution to arrange means for the mechanical actuation of the switching element upon rotation of the rotary member.
  • the invention proposes to convert the rotary actuation of a rotary element into a movement for mechanical actuation of the switching element, as is also the case in the case of a push-button or push-button.
  • a rotational movement of the rotary element thus leads to a mechanical actuation of the switching element, which can be used to a corresponding operation of the household appliance.
  • the invention thus makes it possible to take into account specific design requirements with regard to the arrangement of pushbutton switches and rotary elements.
  • the provided means for implementing the rotational movement in a mechanical actuation of the switching element, the rotary element itself or the Be associated switching element are also to be encompassed by the invention.
  • the means detached from the rotary element or the switching element for example, the housing of a household appliance of an electronic assembly or the circuit board as such assigned.
  • two mechanically actuated switching elements are arranged adjacent to the circuit board, wherein the means for a mechanical actuation of the switching element from the direction of rotation dependent on the one or the other switching element act.
  • Such a configuration makes it possible to detect the direction of rotation of a rotary element and deduce therefrom any conclusions regarding the desired operation.
  • the means for the mechanical actuation of the switching element need only be designed so that they act in one direction of rotation on the one switching element and in the other direction of rotation to the other switching element. From the actual operation of one of the switching elements can then be closed to the direction of rotation and thus to the control request.
  • a housing wall is arranged between the circuit board and the rotary element, wherein the switching element for actuating on the housing wall, a movable actuating element is associated, and wherein the means for the mechanical actuation of the switching element act on the actuating element.
  • the interposition of a housing wall with a movable actuating element makes it possible to further improve the variability with regard to the positioning of the rotary element.
  • the housing wall associated actuator can be configured so that its operation can be done via different pressure points or detached from a specific pressure point. The rotary member can be moved so far relative to the actuating element, resulting in the desired higher variability with respect to the position of the rotary member.
  • the actuating element is designed as a movable, mechanically acting on the switching element tongue.
  • a tongue can be brought along its longitudinal direction independent of a specific pressure point to a deflection.
  • the rotating element can be variably positioned to the tongue.
  • the tongue or generally that movable actuator, the housing wall can be attached via a hinge and in particular via a film hinge. The latter offers itself, if the housing wall is made for example by injection molding of a plastic. In such an injection molding, the housing wall, the movable actuator and the film hinge can be manufactured in one operation.
  • the means for the mechanical actuation of the switching element comprise a control curve extending in the circumferential direction of the rotary element, which, depending on the angle of rotation, brings about an engagement between the rotary element and the switching element.
  • a control cam may be formed, for example, as a slotted guide or as a ramp.
  • the control cam may be provided with specific engagement elements for interaction with the switching element, the engagement means being arranged along the circumferential direction.
  • control cam is designed as a ramp with a continuously varying axial extent in the circumferential direction.
  • a ramp can be easily integrated into production technology, especially in plastic parts.
  • no elaborate molds are required for the production.
  • control cam is associated with the rotary member and is dependent on rotation angle with the switching element or the intermediate actuator of the housing wall into engagement.
  • control cam to the actuating means or the switching element, wherein the means for the mechanical actuation of the switching element further comprises an actuating cam on the rotary member include, the angle of rotation depending on the control cam on the actuating means or the switching element is engaged.
  • the housing wall would differ depending on the provision of a rotary member or a pushbutton switch.
  • the cam could also be placed as a separate component of the switching element or the actuating means.
  • two control cams are provided, which extend starting from a rest position of the rotary member in the respective opposite circumferential direction. Depending on the direction of rotation, either one or the other of the adjacent switching elements would thus be confirmed by means of the control cam. This makes it possible to determine the direction of rotation of the rotary element, so that a corresponding operation request can be derived.
  • a control unit connected to the or each switching element is provided, which is designed to count the number of actuations of the or each switching element. By counting the operations, for example, a sequence of operation requests can be read. For example, each rotational movement can be successively evaluated to increase a heating level of a stove or to select a further program step.
  • control unit may preferably also be designed to allocate the number of actuations to a specific operating request, and to output a control signal corresponding to the operating request.
  • a specific sequence of actuation possibly taking into account pauses etc., could be used to encode a specific user request. Also can simply be coded on the number of successive operations of the control request.
  • control unit is designed to evaluate an actuation, dependent on the direction of rotation of the rotary element, of two switching elements as an incremental addition or subtraction of the number of actuations.
  • the heating level can be increased or a further program step can be selected and the heating level can be lowered or the previous program step selected by an operation in the reverse direction of rotation via a rotation of the rotary element in one direction of rotation.
