  • the control circuit that can be used for this purpose can be designed similarly to the zone switches known from stove tops.
  • the invention can be referred to as a "touchlight” and is based on the detection of a change in capacity on the door handle of the door of the household appliance.
  • the one or more oven lamps or oven lamps are switched on automatically depending on such changes in capacity.
  • the principle of Touchlight can correspond to that of an electronic zone switch for electric cooktops from cookers. Instead of touching the glass ceramic of the hob, however, a sensor input of the electrical control circuit with the door handle of the appliance door, for. B. oven door, electrically connected.
  • the capacitive sensor of the control circuit is connected to the door handle of the door via an electrically conductive path.
  • the line path preferably contains a switch contact.
  • the door handle can be made of stainless steel, aluminum or conductive plastic, whereby the surface can be painted or anodized.
  • the capacity of the door handle measured by the sensor of the control circuit changes depending on the condition of the door, ie depending on whether a person is touching the door handle or not.
  • the state that the door handle is touched and the door is opened can be distinguished from the state that the door is closed by different voltage levels at the capacitive sensor of the control circuit.
  • the electrical control circuit of the lighting device can be linked to a device operating circuit and / or its operating software, so that the
  • Operation of the control circuit of the lighting device is additionally dependent on the respective switching state or operating state of the device operating circuit, for example depending on the respective position of a function selector

  • a stove, oven or a microwave oven contains a device body 2, in which a usable space 4, for example a baking room, grill room, roasting room or the like, an illumination device 6, of which only one lamp is shown , but also several lamps can be present, which in the usable space 4 or through a glass wall can be arranged separately outside for illuminating the usable space 4, and a door 8 for closing the usable space 4.
  • the door 8 is provided with a door handle 10.
  • An electronic control circuit 12 which preferably contains or is connected to a computer or a microcontroller, is connected to the lighting device 6 in order to switch it on automatically as a function of a human touch of the door handle 10.
  • the control circuit 12 is preferably arranged in or on the device body 2. According to an embodiment not shown, it could also be arranged in the door 8.
  • the door handle 10 is designed as a capacitance body, the capacitance of which can be changed by human touch.
  • the door handle 10 is made of electrically conductive material or contains electrically conductive material as part of the capacitance body, which is electrically connected to the control circuit 12 by an electrically conductive path 14.
  • the control circuit 12 is designed to detect the capacity of the door handle 10 and to automatically actuate the lighting device 6 as a function of the capacity of the door handle 10, which is detected by the control circuit by means of a capacitance sensor system contained therein. This detection of the capacitance can be effected by measuring the capacitance value or by a sensor circuit which responds only to predetermined changes in the capacitance values.
  • the electrical conduction path 14 contains an interruption contact arrangement 16 which closes the conduction path 14 when the door 8 is closed (establishes an electrical connection) and interrupts it when the door is opened.
  • the interruption contact arrangement 16 contains a contact part 18 on the door 8 and a contact part 20 which can be contacted by closing the door and which is arranged on the device body 2 in an electrically insulated manner.
  • the two contact parts 18 and 20 are opened by opening the door when the door end provided with the one contact part 18 and away from the pivot axis 22 of the door 8 moves a little away from the device body 2.
  • the contact parts 18 and 20 are automatically brought into electrical contact with one another shortly before the door 8 is completely closed, ie a few tenths of a mm or a few mm before the door is fully closed.
  • the electrical control circuit 12 is also designed to actuate the lighting device 6 depending on whether the interruption contact arrangement 16 and thus also the door 8 is closed or open.
  • control circuit 12 can no longer detect whether the door handle 10 is being touched or not.
  • the control circuit 12 switches on the lighting device 6 when the door handle 10 is touched manually by a user when the door 8 is closed.
  • the control circuit 12 preferably switches the lighting device 6 off again automatically if the door 8 is not opened after this switching on.
  • the control circuit 12 is preferably designed such that it automatically switches the lighting device 6 off again after the door 8 is closed.
  • the invention results in a simple construction an operationally reliable control of the lighting device 6.
  • the control circuit 12 in or on the device body 2 instead of in the door 8, the door is lighter.
  • the control circuit 12 can be connected to a device operating circuit 24 or can be partially formed by such a device and can be designed to switch the lighting device 6 depending on the respective switching state of the device operating circuit 24, for example in such a way that the lighting device 6 can only be switched on if that too Household appliance are switched on via an operating element 26 and thus also the appliance operating circuit 24.
  • control circuit 12 is designed as a dimmer circuit, by means of which the lighting device 6 automatically switches from the switched-off state to a fully intensified lighting state (dimmer state) when it is switched on.
  • control circuit 12 is designed as a dimmer circuit, through which the When switching off, the lighting device 6 automatically changes from the completely switched-on state slowly to the completely switched-off state via a dimmer state.
  • Such a dimmer circuit is particularly advantageous when the lighting device 6 is switched off because the user can then observe the useful space 4 and in particular its contents for a while during the dimmed switch-off process.
  • a dimmer process When switched on, a dimmer process has the advantage that a user is not suddenly blinded by the light.
  • part of the electrical conduction path 14, which is located in the door 8 is designed as a fastening element for fastening the door handle 10 to the door 8.
  • a door part 28 at the upper door end of the door 8 consists, for example, of electrically insulating material, e.g. B. plastic, and contains a through hole 30.
  • Handle 10 screwed.
  • a screw 38 is screwed which is in electrical contact with the tube 32 and also with a plate-shaped contact part 18 of the interruption contact arrangement
  • the screw 38 clamps the contact part 18 against the door part 28 on the inside of the door by means of a screw head, a shoulder 42 of the handle 10 being supported on the outside of the door. If the door part 28 is made of an electrically conductive material or is provided with an electrically conductive cover layer 44, between the
  • Insulating washer 46 made of electrically insulating material can be used.
  • the other, provided on the device body 2 contact part 20 (and / or the one contact part 18) is spring-mounted in the door closing direction by a compression spring 48. This ensures reliable contacting of the two contact parts 18 and 20, as well as a tight closing of the door 8 on the front of the useful space 4, if the parts are manufactured with large tolerances or material deformations occur due to temperature changes.
  • the handle 10 is made of electrically conductive material, its capacity changes when it is touched by a person because a capacity is added by the person. If the handle 10 has a surface of electrically insulating material and an electrically conductive core therein, the capacitance of the handle 10 changes when it is touched by a person in a manner similar to that of a plate capacitor, the capacitance can be changed by changing the medium between them capacitor plates.
