A cooktop appliance or heating element, as provided herein, may include a sensor support assembly positioned within a heating zone of the heating element. The sensor support assembly may include a shroud cover and a thermostat. The thermostat may be mounted to the shroud cover. The thermostat may include a base and a top cap held on the base. The top cap may be positioned above the shroud cover and spaced apart therefrom. A vertical air gap may be defined between the top cap and the shroud cover.

According to one example, a system includes a heat source operable to provide an amount of energy to be used to cook a food item. The system further includes a processor operable to establish a first communication link with a wireless device having a cooking recipe for the food item. The processor is further operable to receive, via the first communication link, an indication of a first temperature associated with the cooking recipe. The processor is further operable to establish a second communication link with a cooking device system operable to be used in cooking the food item, and to receive, via the second communication link, an indication of a current temperature associated with the food item. The processor is further operable to, based on the indication of the first temperature and the indication of the current temperature, adjust the amount of energy provided by the heat source.

Examples are disclosed herein that relate to a cooking system having multiple heating elements for heating a cooking surface. One example provides a cooking system, comprising a continuous cooking surface comprising a plurality of individually controllable heating zones, and for each heating zone, a temperature sensor configured to detect a temperature for the heating zone separately from the temperatures of other heating zones, and a heating element disposed beneath the heating zone and configured to provide heat to the heating zone. The cooking system further comprises a controller configured to individually control the heating element of each heating zone.

A stove guard comprises a data processing unit (101) and a temperature sensor arrangement (102) for receiving thermal radiation from objects in a specific field of view and for supplying detector signals representative of the received thermal radiation to the data processing unit (101). The temperature sensor arrangement (102) includes at least three detector elements (201, 202, 203), their sensitivity bands located at different positions along an optical radiation wavelength axis. The sensitivity band of one of said detector elements is limited to a wavelength range of less than 1.2 micrometers.

A cooktop appliance or heating coil assembly may include a heating element, a shroud cover, a thermostat, and a spring bracket. The shroud cover may be disposed within the heating element. The shroud cover may include a top wall defining an upper surface and a lower surface. The thermostat may extend vertically between a distal end and an interior end below the distal end. The distal end may be disposed against the shroud cover at the lower surface. The thermostat may be connected in series between the first and second coil sections of the spiral wound sheathed heating element. The spring bracket may be disposed against the shroud cover at the lower surface and bias the shroud cover upward.

An induction heating type cooktop includes an upper plate coupled to a top side of a case and configured to place an object to be heated on a top of the upper plate, a working coil disposed inside the case to heat the object, a thin film disposed on at least one of a top surface or a bottom surface of the upper plate, an insulator disposed between the bottom surface of the upper plate and the working coil, and a temperature sensor configured to measure a temperature of at least one of the thin film or the upper plate by a plurality of thermocouples.

A wirelessly operable cooking appliance for cooking food products includes a wireless communication device. A computing device, such as a smartphone, can wirelessly communicate with the cooking appliance to control and monitor the cooking appliance.

The present disclosure relates to an apparatus and a method for estimating a state of an object to be heated based on sound which is generated when the object to be heated is heated, and providing the estimated information to other devices in an Internet of Things (IoT) environment through a 5G communication network. The heating apparatus may include a housing having a receiving space therein, a heating member disposed within the housing, a power supplier for supplying power to the heating member, a top plate disposed on the top of the housing to support the object to be heated, a sound sensor disposed on the bottom of the top plate, and a controller for predicting the state of the object to be heated by using a deep neural network model that has been trained through machine learning based on a sound signal received from the sound sensor.

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.

An induction heating type cooktop includes an upper plate coupled to a top side of a case and configured to place an object to be heated on a top of the upper plate, a working coil disposed inside the case to heat the object, a thin film disposed on at least one of a top surface or a bottom surface of the upper plate, an insulator disposed between the bottom surface of the upper plate and the working coil, and a temperature sensor configured to measure a temperature of at least one of the thin film or the upper plate by a plurality of thermocouples.
