  • Patent number: 8035063
    Abstract: A power control system for an electric cooktop. The power level is set by a knob connected to a potentiometer. Potentiometer information is digitally communicated by a controller over a serial communication bus to a power unit. The power unit communicates power level display information back to the controller over the same serial communication bus. The display information is displayed as numbers on a digital display by the controller. The power unit controls a heating element of the cooktop according to the potentiometer information. A second potentiometer can be added to control a second heating element by operating as a slave to the first controller. Further, multiple heating elements can be controlled by a single potentiometer by dividing the angular rotation into multiple segments or ranges.

  • Patent number: 8008605
    Abstract: An electronic cook top control system has a cooktop including a heating element. An electronic controller is operatively connected to the cooktop. A rotary position input is operatively connected to the electronic controller. The electronic controller controls a heating level of the cooktop in a first manner in response to rotation of the rotary position input in a first direction. The electronic controller controls the heating level of the cooktop in a second manner in response to rotation of the rotary position input in a second direction.

  • Publication number: 20060113295
    Abstract: Provided is a cooking appliance, such as a convection cooking appliance. The appliance includes a heating element, an annunciator, and a user interface for receiving a plurality of control settings from a user. The control settings include a time setting. The appliance further includes a controller operatively connected to the user interface for provision of the plurality of control settings to the controller. The controller includes an alarm point determination section for determining an alarm point based on the time setting, an annunciator control section for controlling the annunciator based on the alarm point, wherein the annunciator produces periodic annunciations, and a repeat period determination section for determining a repeat period for the periodic annunciations.

  • Patent number: 7022949
    Abstract: A multiple-zone power control system for controlling electric heating elements, including a power control unit having multiple control zones, a touch-sensitive function key, and a touch-sensitive on/off key for activating and deactivating one of the control zones. When all of the control zones are deactivated, the touch-sensitive key must be touched for at least a cold start duration in order to activate the designated control zone. Alternatively, the designated control zone is prevented from being activated if the touch-sensitive function key is touched while the touch-sensitive on/off key is being touched. The control system also includes two power controllers connected by a communication bus. When one of the power controllers initiates a lockout condition, the other power controller initiates a corresponding lockout condition. Multiple heating elements can be controlled together using a single set of control keys. A element size key toggles between different combinations of heating elements to control.

  • Patent number: 5940579
    Abstract: A heating panel has a resistive heating layer formed on a substrate. Insulating layers can be formed on the substrate. The heating layer has electrodes on opposite edges connected to different phases of a multiphase power source. Capacitive currents caused in the substrate by the different phases cancel each other. Thus, leakage current is minimized through a conductor connected between the substrate and ground. The heating panel can be adapted for two phase or three phase systems. The heating panels are particularly useful for defining a heating cavity of an oven or pots on a cook top.

  • Patent number: 5577158
    Abstract: A heating panel has a metal substrate, ceramic inner and outer insulating layers on the substrate. A film of resistive material forms a heating layer on one of the insulating layers. The heating layer has electrodes on opposite edges connected to different phases of a multiphase power source. Another electrode is connected to a neutral of the power source. Capacitive currents caused in the substrate by the different phases cancel each other. Thus, leakage current is minimized through a conductor connected between the substrate and ground. The heating panel can be adapted for two phase or three phase systems. The heating panels are particularly useful for defining a heating cavity of an oven.
