An electric heating plate for electric cooking apparatuses is provided with the capability to prevent unintended ignition of cooking oil. The heating plate includes an electric heating conductor as the heat source and a temperature controller electrically connected with the heating conductor, sensing the temperature of the cooking vessel, controlling the heating plate output power, and limiting the temperature of the cooking oil in the cooking vessel. With this heating plate, the electric cooking apparatus will be able to prevent cooking oil ignition during cooking, while the minimum cooking temperature for a daily cooking is still maintained.

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.

In a method for controlling a cooking appliance having a heating device and an internal cooking appliance controller by means of an external control unit connected to a temperature sensor, a first step involves a plausibility check on the control commands and/or on the current operating state of the cooking appliance being performed for a temperature of a cooking vessel that has been put on. Differences for the plausibility check result in a release of power being reduced as a safety measure. A heating device controlled by the external control unit then has its power level and/or heating time period limited as the actual power and/or actual heating period when the heating device is actuated.

If hobs are integrated into built-in furniture, care must be taken to ensure that during operation the temperature in or on the built-in furniture does not exceed permissible limit values. It is proposed to fasten a temperature sensor in the hob housing by means of a heat-conducting retaining element. The retaining element is arranged on the hob housing such that essentially the heat output into the worktop is transmitted via the retaining element to the temperature sensor.

According to one example, a system comprises a heat source system and a processor. The heat source system comprises a plurality of heat sources. Each heat source is operable to provide an amount of energy to be used to cook a food item during a cooking process. The processor is operable to determine that a cooking device system has been positioned on or in a first heat source of the plurality of heat sources, determine an identity of the cooking device system that has been positioned on or in the first heat source, and correlate the determined identity of the cooking device system with an identity of the first heat source.

A low profile spring bracket for a heating element of a cooktop appliance includes features that allow the bracket to move along the axial direction in a smooth fashion with minimal force. In this way, a temperature sensor attached thereto can maintain contact with a cooking utensil placed on the heating element.

The inventive concept provides an apparatus and a method for heat-treating a substrate. The method includes a first treatment operation of spacing a substrate apart from a support plate provided with a heater to a first height in a state in which a treatment space, in which the substrate is treated, is closed and heating the substrate, a second treatment operation of, after the first treatment operation, lowering the substrate such that the substrate is located at a second height and heating the substrate, a third treatment operation of, after the second treatment operation, lifting the substrate such that the substrate is spaced apart from the support plate to be located at a third height and heating the substrate, and a fourth treatment operation of, after the third treatment operation, lowering the substrate such that the substrate is located at a fourth height and heating the substrate.

A cooktop appliance may include a top panel, a heating element, a temperature probe, a griddle plate, and a support post. The temperature probe may be attached to the top panel and be horizontally spaced apart from the heating element. The griddle plate may be selectively disposable in a griddle-cook position above the top panel along a vertical direction. The griddle plate may have a top cooking surface and a bottom heating surface. The top cooking surface may extend perpendicular to the vertical direction in the griddle-cook position to receive a cooking item thereon. The bottom heating surface may be disposed beneath the top cooking surface and face the top panel in the griddle-cook position to receive a thermal output from the heating element. The support post may extend downward from the griddle plate in conductive thermal communication with the temperature probe in the griddle-cook position.

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 stovetop burner protector, in some embodiments, may provide for a covering device for stoves that may comprise a heat-conducting plate ringed by a high heat-resistant element, which may be configured to cover one or more stovetop burners. The present invention's heat-resistant element may be configured so as to catch or divert the path of any liquids or solids that may be dispersed by the cooking process. At least one small dome-shaped opening on the side of the heat-resistant element may be configured to let out some or all of the hot air.
