A power circuit for controlling power to a heating element includes an electric resistive element and a thermal switch assembly in series. The thermal switch assembly includes a first contact connected to the electric resistive element, a second contact, and a bimetal element configured to electrically connect and disconnect the first and second contacts. The bimetal element establishing an electrical connection between the first and second contacts when a temperature of the bimetal element is below a predetermined cut-off temperature, and no longer electrically connecting the first and second contacts when the bimetal element is at or above the predetermined cut-off temperature. A first voltage is applied to the electric resistive element when the bimetal element electrically connects the first and second contacts and a second voltage, lower than the first voltage, is applied to the electric resistive element when the bimetal element electrically disconnects the first and second contacts.

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 cooking appliance can include an upper plate configured to support an object to be heated; a working coil configured to generate magnetic fields for heating the object; a temperature sensor configured to sense a first temperature of the upper plate; at least one sub temperature sensor configured to sense a second temperature of the upper plate; and a sensor support member including a main mounting portion and a sub mounting portion, the temperature sensor being mounted on the main mounting portion and the at least one sub temperature sensor being mounted on the sub mounting portion. Also, the sensor support member is disposed in a direction extending away from a center of the working coil.

The present invention relates to an induction cooking system and, more specifically, to an under-induction cooking system which can accurately match a pad and an induction cooker, used as one set, and, simultaneously, ensure safety in use by multiple ways, thereby preventing an accident, such as fire caused by the induction cooker, in advance.

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 appliance is provided including a top panel, an electric heating element, a drip pan, and a temperature switch. The drip pan may be attached to the top panel and positioned below the electric heating element. A switch bracket may be mounted to the top panel and may include a cantilevered mounting plate that is biased toward or interferes with the drip pan. The temperature switch may be mounted to the mounting plate using two elongated pins passing through two apertures in the mounting plate such that the temperature switch may pivot relative to the mounting plate and self-align with the drip pan. The temperature switch may be operable to limit the power supplied to the electric heating element at a predetermined temperature.

A cooktop apparatus, in particular an induction cooktop apparatus, includes at least one glass unit and at least one coating configured as a multilayer structure, which is disposed on at least one subregion of at least a main face of the glass unit and has at least two layers. In order to achieve optimum compatibility with the sensors of the user interface without requiring a process after deposition, at least one of the layers is formed by at least one semiconducting material, to fulfill the function of an absorbing layer.

A cooking appliance includes a housing, and a cooking element disposed in the housing and configured to generate energy for cooking food, and a controller coupled to the cooking element and configured to communicate a control signal to selectively actuate a residential heating, ventilation and/or air conditioning (HVAC) system and/or non-cooking device in connection with cooking food with the cooking element

The present invention relates to induction heating devices and systems. More particularly, the present invention relates to induction heating systems that may be used with, or include, radiators. A heating system described herein includes a radiator and an induction heating device attachable to the radiator, the induction heating device configured to heat at least a portion of the radiator via induction.

A system and method for induction cooking using an induction cooking unit, an interface adapted to receive, store, and execute a plurality of instructions of a multistage programmable recipe using the induction cooking unit, a power supply, a controller coupled to said power supply, said interface, and said induction cooking unit.
