A heating appliance includes a translucent cooktop and a burner in communication with the cooktop. The burner is operable between deactive and active states. The upper surface of the cooktop defines a cooldown state after the burner is moved from the active to the deactive state. A light module includes a light source and is in an illuminated state when the burner is in the active state and when the cooktop is in the cooldown state. A light guide extends from the light module and around a portion of the burner. The light guide is positioned such that the light source directs light through the light guide. The outer surface of the light guide includes a formed surface that directs light upward and through the cooktop, wherein the light guide is visible through the cooktop when the light module is in the illuminated state.

A glass-ceramic cooking apparatus and a method relating to temperature limiting control of the glass heating area for preventing cooking oil ignition is disclosed. The apparatus comprises at least one glass surface, at least one heat source under the glass to create a heating area on the glass, one temperature sensor and one control unit for each heat source, wherein the sensor measures the temperature on the underside the glass heating area, and the control unit is electrically connected with the heat source, compares the measured glass temperature with predetermined upper and lower temperature limits that are based on a corresponding relationship between the heating area temperature and the cooking oil temperature within the cooking vessel, and then reduces or increases the output power of the heating source, so that the maximum temperature of the cooking oil in the cooking vessel can be limited in a range that is below the cooking oil ignition point while a minimum temperature can still be maintained for a desired cooking performance.

A cooktop appliance is provided herein. The cooktop appliance may include a ceramic plate, an electric heating element, a temperature sensor, and a thermal conduction strip. The electric heating element may be positioned below the ceramic plate. The electric heating element may define a horizontal length from a center point projected on the ceramic plate. The temperature sensor may be positioned between the ceramic plate and the electric heating element relative to a vertical direction. The temperature sensor may be spaced apart from the ceramic plate and the electric heating element. The thermal-conduction strip may be attached to the temperature sensor. The thermal-conduction strip may extend in contact with a bottom surface of the ceramic plate between an inner tip proximal to the center point and an outer tip distal to the center point.

A heat modulating system includes a heat source, a temperature sensor proximate the heat source, and a controller in connection with the temperature sensor and the heat source. The controller modulates a rate of temperature increase of the heat source based on temperature detected by the temperature sensor, and at a temperature set point detected by the temperature sensor the controller modulates power to the heat source to help to prevent unintended autoignition of cooking oil.

A magnetic stirrer (11) comprises a magnetic drive and a placement surface (17) for a laboratory vessel containing a substance to be stirred. The magnetic drive is designed to generate a magnetic field which varies such that a magnetic stirring element can be driven to produce a stirring motion in the laboratory vessel, in order to stir the substance. The magnetic stirrer (11) also comprises a heating device (15), which is designed to heat the placement surface in order to heat up the substance, and a display device (23), which is designed to display the current temperature of the placement surface.

A heating element that limits the maximum temperature readied by a cooking utensil or food items placed on the heating element is provided. A cooktop appliance with features for limiting the maximum temperature reached by a cooking utensil or food items placed on a heating element of the cooktop appliance also is provided. In particular, a cooktop appliance with a positive temperature coefficient heating element and a controller for regulating the heating element to a selected temperature or heat output is provided.

A cooking device safety system includes a stovetop cooking device with a first sensor to detect the presence of an object on or adjacent to a burner; a second sensor to detect a condition of the burner; a transceiver to send a signal from the first and/or the second sensor to a remote device; a microcontroller with a timer; and a signal output device. A method for providing a safe cooking device environment includes detecting a status of a cooking device and detecting the presence of an object on or in the cooking device. When the cooking device has an activated status and an object is detected, the system detects whether a threshold cooking time has been exceeded. If the threshold has been exceeded, the system produces an alert via a signal output device; and/or sends an alert to a remote device; and/or inactivates the cooking device.

A cooktop system is configured to detect cooking events during a cooking process performed on a cooktop. The system includes a cooktop having one or more cameras integrated into the cooking surface and a controller that is configured to receive the image data generated by the cameras, process the image data to identify a corresponding cooking event, and perform a response function based on the identified cooking event.

A cooking apparatus with a cooktop composed of a glass or glass-ceramic material is provided. The cooking apparatus includes a heating element and a lighting element that are disposed in the region below the underside of the cooktop. The heating element is applied to the underside of the cooktop indirectly by a pressing device or directly by pre-stressing one or a plurality of spring elements. The lighting element and the heating element are disposed on a common support section of the pressing device in such a way that they are adjustable with an oscillation of the cooktop.

A display device is provided that is a transparent, colored glass-ceramic with a display face on the front, an illumination face on the back, and at least one light-emitting element being disposed in the region of the illumination face. The display device further includes a color compensation filter in the form of a color layer introduced directly or indirectly on the glass ceramics.
