Definitions

  • the present invention relates to a control panel for controlling several different functions of an appliance, in particular of a cooker having a ceramic cooktop.
  • Control panels of the above mentioned kind are already known in many different designs. They normally comprise several actuating elements, in particular in form of touch sensitive switches or proximity switches, which can be operated by a user for choosing a function of the appliance. Moreover, the control panels include a controller, which is connected to the actuating elements for controlling the function chosen by the user. In order to indicate current operating conditions of the appliance, several lights, in particular LEDs, are connected to the controller and are arranged in such a manner, that they form several displays, e.g. one display for each controllable unit of the appliance, such as one display for each cooking field of a cooker.
  • the most common display designs are the seven segment display design and the bargraph display design. Both display designs may be supplemented by further displays, e.g. so-called on/off-displays, which are normally formed by a single LED.
  • each producer uses one or more particular control panel designs.
  • divers display designs are used to distinguish different type series of appliances of the same producer.
  • control panel suppliers need to manufacture many different control panels having many different designs.
  • this multitude of designs increases the manufacturing costs of control panels.
  • the plurality of different assembly lines for the different control panel designs causes high extra costs.
  • the present invention provides a control panel for controlling several different functions of an appliance, such as a cooker having a ceramic cooktop.
  • the control panel comprises at least one actuating element, in particular a touch sensitive switch or a proximity switch, which can be operated by a user for choosing a function of the appliance; a controller, which is connected to the at least one actuating element for controlling the function chosen by the user; and a plurality of lights, in particular LEDs, which are connected to the controller and which are arranged in such a manner, that they form at least a first display and a second display, in particular a seven segment display and a bargraph display, for indicating current operating conditions of the appliance.
  • the controller is preadjusted in such a manner that it controls either exclusively the first display or exclusively the second display. In other words, although two different displays are available, only one of these displays is put into operation, whereas the other display is not used at all.
  • the setting of the controller can be performed by the manufacturer of the control panel or by the producer of the appliance. If the control panel comprises more than two displays, at least one of the displays is set out of operation by means of the setting of the controller.
  • the present invention provides a control panel for controlling several different functions of an appliance, said control panel comprising at least one actuating element, in particular a touch sensitive switch or a proximity switch, which can be operated by a user for choosing a function of the appliance; a controller, which is connected to the at least one actuating element for controlling the function chosen by the user; and a plurality of lights, in particular LEDs, which are connected to the controller and which are arranged to form at least a first display and a second display, in particular a seven segment display and a bargraph display, for indicating the chosen function and/or an operating condition of the appliance; wherein the controller is preadjusted in such a manner that it controls either exclusively the first display or exclusively the second display or both.
  • the controller is preadjusted in such a manner that it controls either exclusively the first display or exclusively the second display or both.
  • the manufacturer of the control panel or the producer of the appliance can decide by preadjusting the controller, whether he wishes to put into operation exclusively the first display or exclusively the second display or both displays.
  • the control panel according to the second aspect of the present invention provides one option for selection more than the control panel according to the first aspect of the present invention.
