Definitions

  • the present invention relates to an illuminated rotary knob for use in a household appliance, in particular a domestic oven.
  • a household appliance in particular an oven generally has a panel and a rotary knob which is disposed onto the panel. The user manipulates the rotary knob in order to turn the appliance on or off and to regulate the heating level of the heat source.
  • the rotary knob generally has a hub which is mountable onto the regulator shaft of the gas valve or the regulator shaft of the electrical switch depending on the type of the oven, and a pointer which indicates the operative state of the oven which is set by the user.
  • a rotary knob is frequently provided with an illuminated transparent indicator.
  • US 2005/0236263 A1 discloses a control knob with a multi-color indicator.
  • the user can reliably ascertain by means of the illuminated indicator the current operative state of the household appliance.
  • the indicator escapes from the eye of the user, for example when the user stays at a particularly unfavorable position and/or the indicator is soiled.
  • the user cannot reliably recognize the actual operative state of the household appliance. In such case there is a risk of fire and explosion.
  • An objective of the present invention is to provide a rotary knob for use in a household appliance, in particular an oven which overcomes the aforementioned drawbacks of the prior art in a cost effective way and which enables the user to operate the household appliance more reliably and safely.
  • the rotary knob of the present invention comprises a transparent collar whose inner side faces an illuminating device of the household appliance and outer side faces a user who is located in front of the panel, a non-transparent body which is interposed between the transparent collar and the transparent indicator and a cavity inside the non-transparent body for transmitting the light from the transparent collar to the inner side of the transparent indicator.
  • both the collar and the indicator of the rotary knob can be entirely illuminated by the illuminating device of the household appliance.
  • the user can more easily and reliably ascertain the current operative state of the household appliance. For example if the user fails to see the illuminated indicator due to an unfavorable view point or a reduced sight, then the illuminated collar will easily attract the attention of the user. Thereby, the user can be protected from being misled and is prompted to take a closer look at the position of the indicator.
  • the rotary knob of the present invention is physically separate from the stationary illuminating device of the household appliance, and thus can be entirely removed from the panel, in particular from the regulator shaft for cleaning or replacement. Thereby, the customer satisfaction can be increased.
  • the inner side of the transparent collar has a plurality of apertures which let the light emitted from the illuminating device to pass into the cavity, and therefrom to the indicator.
  • the apertures are radially formed around a central bore of the transparent collar which defines a transparent hub for releasably receiving the regulator shaft.
  • the present invention also provides an oven.
  • the oven comprises at least one rotary knob which is releasably held by the regulator shaft, and an illuminating device for illuminating the rotary knob.
  • the illuminating device emits light in response to the rotational position and/or movement of the regulator shaft.
  • the rotational position and/or movement of the shaft are detected by a detection unit.
  • the illuminating device is fixed behind the panel at a location which faces the transparent collar of the rotary knob. Thus, when the illuminating device emits light, then the transparent collar and the transparent indicator are both illuminated.
  • the detection unit comprises a rotary encoder.
  • a switch can be used.
  • the illuminating device emits solely green light when the rotatory knob is at the rest position.
  • the transparent collar and the transparent indicator are both illuminated with green light at the rest position.
  • the illuminating device emits solely red light when the rotatory knob is moved from the rest position to any operative position.
  • the transparent collar and the indicator are both illuminated with red light.
  • the user is alerted that the corresponding heat source is in operation.
  • the user can also easily become aware that the illumination device is malfunctioning when the collar of the rotary knob emits neither green light nor red light. Thereby, the user can be protected from misidentifying the actual operative state, when he or she fails to see the position of the transparent indicator.
  • the illuminating device has a plurality of red light sources and a plurality green light sources which are alternately arrayed around the rotational axis of the regulator shaft so as to uniformly illuminate the transparent collar and the transparent indicator.
  • the red light sources and the green light sources can be separately activated in response to the rotational position of the regulator shaft.
  • an array of color changing light sources is used to emit either red light or green light.
  • the light sources comprise light emitting diodes (LEDs).
  • colored lamps can be sued.
  • the light sources of the illuminating device are immovably disposed onto the surface of a plate located behind the panel.
