A food warming system involving a heat sink component, a warming plate, and an intervening insulation and heat- or fire-resistant layer that moderates the flow of heat from a charged heat sink component to the warming plate on which a vessel containing food is placed to maintain food in a heat-regulated state.

An induction cooking hob and a method for heating food as well as a computer program product are disclosed. Based on information of a micro-electromechanical system (1500) in combination with a temperature sensor associated to a heating zone, vibrations can be detected and a heating zone associated with the boiling substance can be properly discriminated from one supporting a pot having a non-boiling substance in it. Subsequent simmering of the substance can be automatically effected. An indication will be provided to a user (1680), and an automated function can be started (1610) including boiling and subsequent simmering, respectively indication of a boiling substance on any of the heating zones on an induction hob (1000).

There is provided a placement position determining part that calculates a rising gradient of an output value of the infrared sensor every after passage of a first predetermined time and performs a placement position determining operation of determining that a placement position of a cooking vessel is improper when the rising gradient is smaller than a first threshold value, and the placement position determining part performs the placement position determining operation after a lapse of a second predetermined time from the start of heating, thereby accurately determining that the cooking vessel is improperly placed on a top plate and preventing overheating of the cooking vessel.

A device for heating an object adapted to be heated by magnetic induction and comprising a thermally insulating spacer to be placed between the heat-retaining object and a support. The device also includes a control and induction heating unit, which includes an inductor, a temperature sensor for detecting the temperature of the support, and an inductor control unit connected to the temperature sensor for controlling the inductor, such that the electromagnetic field is induced according to the readings from the sensor. The inductor control unit limits the magnitude of the electromagnetic field when the detected temperature reaches a predetermined threshold lower than a degradation temperature of the support.

A stove guard arrangement includes sensors for detecting events on a stove and for providing detection data, and a programmable processing component for analysing the detection data and for providing exceptional situation data in response to the detection data indicating an exceptional situation defined in the programming of the processing component. The stove guard arrangement comprises a receiver connected to the processing component and arranged to receive radio-frequency interference and to provide corresponding reception data. The processing component is arranged to recognize regular changes in said reception data and derive, on the basis of the recognized regular changes, a conclusion that the stove is an induction stove.

Apparatus for an aerosol generating system comprises an inductive element for inductively heating a susceptor arrangement to heat an aerosol generating material to thereby generate an aerosol, an insulating member which in use is located between the inductive element and the susceptor arrangement to thermally insulate the susceptor arrangement from the inductive element; a temperature sensor for measuring a temperature at a location in the system insulated in use from the susceptor arrangement by the insulating member, and a control arrangement. The control arrangement is configured to monitor the temperature measured by the temperature sensor and take a control action if, based on the temperature measured by the temperature sensor, the control arrangement determines that the susceptor arrangement is overheating.

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.

A method for controlling an induction heating apparatus of one embodiment comprises starting to heat a container, obtaining an inductance value of the container, calculating an overheating determination index based on the inductance value, comparing the overheating determination index with a predetermined first reference value, and determining whether to stop heating the container based on results of the comparison between the overheating determination index and the first reference value.

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 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.
