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 differnent 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.
  • the controller is preadjusted in such a manner that it controls either exclusively the first display or exclusively the second display.
  • two different displays are available, only one of these displays is put into operation, whereas the other display is not used at all.
  • the decision, which display is used an which one is put out of operation comes with the setting of the controller.
  • 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.
  • control panel comprises a first circuit board, on which the plurality of lights is mounted. Moreover, a number of other electronic components may be arranged on said first circuit board. Moreover, the control panel comprises a mask layer, which is arranged above the circuit board and comprises a plurality of throughholes allowing the light emitted from the lights of the underlying first circuit board to pass.
  • a second circuit board is provided, which is arranged above the mask layer and on which the at least one actuating element is mounted.
  • the control panel comprises a cover layer, which is arranged on the second circuit board, whereas the cover layer is at least partially translucent and serves as a user interface.
  • the cover layer may be, e.g., the ceramic field of a cooker having a ceramic cooktop.
  • icons symbolizing current operating conditions or functions of the appliance which can be chosen by the user, are arranged on the cover layer, e.g. by means of a printing technique or the like, in order to inform the user about the kind of operating condition or function.
  • such icons may be provided in the mask layer in the form of specially designed throughholes, which are lighted by lights arranged on the first circuit board.
  • At least some of the lights form a part of the first display as well as a part of the second display.
  • the number of lights which is put out of operation by means of the setting of the controller can be decreased. Accordingly, the production costs can be reduced.
  • the present invention provides a domestic appliance comprising a control panel of the above mentioned kind.
  • the domestic appliance may be a cooker, an oven, a dishwasher, a washing machine, a dryer, etc.
  • the present invention provides a method for manufacturing a control panel for controlling functions of an appliance.
  • the method comprises the steps of providing at least one actuating element, which can be operated by a user for choosing the function of the appliance; providing at least one controller for controlling the function chosen by the user; providing a plurality of lights, in particular LEDs, and arranging them 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 a current operating condition of the appliance; connecting the at least one actuating element and the plurality of lights with the controller; and preadjusting the controller in such a manner, that it controls either exclusively the first display or exclusively the second display.
  • the method further comprises the steps of mounting the plurality of lights on a first circuit board; arranging a mask layer above the first circuit board, said mask layer having a plurality of throughholes allowing the light emitted from the lights to pass; arranging a second circuit board above the mask layer, said second circuit board comprising actuating elements, in particular touch sensitive switches or proximity switches, for choosing different functions of the appliance; and arranging a cover layer above the second circuit board, said cover layer is at least partially translucent and serves as a user interface.
  • the lights form several seven segment displays and several bargraph displays, whereas the controller is set in such a manner, that only the seven segment displays or only the bargraph displays are controllable by the controller.
  • FIGS 1 and 2 show a control panel 10 according to an embodiment of the present invention.
  • the control panel 10 comprises a first circuit board 12, on which several electronic components are mounted, amongst others a plurality of LEDs 14, which are arranged solitary or in accumulations in order to form several displays as it will be described in more detail below.
  • the control panel 10 comprises a mask layer 16, which is arranged above the first circuit board 12 and comprises a plurality of throughholes 18, each being arranged congruent with one or more LEDs 14 of the underlying first circuit board 12. Accordingly, the light emitted from the LEDs 14 can pass the mask layer 16 through the throughholes 18.
  • a second circuit board 20 is provided, on which a plurality of square and line shaped actuating elements 22 is mounted, e.g. in form of touch sensitive switches, proximity switches etc. Moreover, cutouts 24 are formed in the second circuit board 20, each cutout 24 being arranged congruent with one or more throughholes 18 in order to let the light emitted from the LEDs pass therethrough.
  • the control panel 10 is used for controlling functions of a cooker having a ceramic cooktop, which is not illustrated in the figures.
  • a portion of the ceramic cooktop forms a cover layer 26 of the control panel 10, which is arranged on the second circuit board 20 and serves as a user interface. Due to the translucent material of the ceramic cook top, the light, which is emitted from the LEDs 14 and passes through the throughholes 18 of the mask layer 16 and the cut outs 24 of the second circuit board 20, is visible when regarding the ceramic cook top.
  • a controller 26 is provided, which is connected to the actuation elements 22 for controlling the function chosen by the user, as well as to the plurality of LEDs 14 in order to indicate the current operating condition of the appliance.
