A heating cooker includes a top plate on which a container that accommodates an object to be heated is placed, a heater that heats the container placed on the top plate from below, and a projector that is at least partly disposed below the top plate and that projects an image diagonally upward.

According to various embodiments, an electronic device attachable to and detachable from a side of a cooking vessel that is heated based on a magnetic field generated from an induction cooktop includes: a magnetic harvester circuit configured to generate electric energy based on the magnetic field generated from the induction cooktop based on the electronic device being attached to the side of the cooking vessel; a temperature sensor configured to be driven based on the electric energy and configured to detect a temperature; and a communication circuit configured to transmit the temperature to the induction cooktop.

The present disclosure relates to a loaded-object sensor and an induction heating device including the loaded-object sensor. The loaded-object sensor has a cylindrical hollow body with a sensing coil wound on its outer surface. Further, a receiving space formed inside the body of the loaded-object sensor accommodates a temperature sensor. The loaded-object sensor is concentrically provided in a central region of the working coil. The sensor may measure the temperature of the loaded object while discriminating a type of the loaded object placed on a corresponding position to the working coil.

A system to warm contents in a tray is provided. The system includes an induction heating system a resting surface, and a temperature detector disposed upon the resting surface such that a pan that is disposed upon the resting surface contacts the temperature detector. The temperature detector includes an RTD and associated wiring, a first housing that receives the RTD, and a grommet disposed around the first housing. The temperature detector additionally includes a cylindrical second housing that supports and receives a portion of the first housing therewith and through a first end of the second housing. The grommet includes an arcuate portion that is biased in a direction upwardly from the resting surface, the arcuate portion comprises a central opening through which the first housing extends, wherein the central opening defines an inner circular surface that is disposed between the first and second housings.

The present invention makes it possible to easily cook a desired dish by properly controlling heating temperatures of objects to be heated in cookware in accordance with a cooking procedure. The cooking device 10 is provided with: a heating unit 11 for heating cookware C containing objects to be heated such as water, oil, and ingredients; a temperature detection unit 12 for detecting a temperature of the objects to be heated and/or a temperature of a bottom exterior surface of the cookware C; and a control unit 18 for controlling the heating unit 11 on the basis of the temperature detected by the temperature detection unit 12 such that the temperature of the objects to be heated in the cookware C or a surface temperature of a bottom interior surface of the cookware C matches a cooking temperature set in a cooking process included in cooking execution information.

A cooking appliance apparatus, in particular an oven apparatus, includes a first heating element, a second heating element, a control unit configured to jointly operate the first and second heating elements to heat a cooking chamber in an operating state, and a power distributor unit which is configured to divide a total power into a first output power and a second output power in the operating state and to supply the first output power to the first heating element and the second output power to the second heating element.

An induction range apparatus includes a controller determine whether the container is disposed on the working coil, and the container disposed on the working coil is heated through induction heating, in a container sensing mode, and configured to output a block signal so that induction power outputted from an inverter driver is prevented from being input into a first detector, in an induction heating mode; and a blocking part outputting the induction power input from the inverter driver to the working coil or preventing the induction power input from the inverter driver from being input into the first detector or outputting the sensing signal to the working coil, on the basis of any two or less of the input of the induction power from the inverter driver, the input of the unblock signal from the controller, and the input of the block signal from the controller.

In the interests of improved temperature detection and temperature control of a cooking appliance on a hob by means of an induction coil, the cooking appliance has specific and individual identification. This can be contained in an NFC tag, by way of identification means. This identification can be read out on a hob, either by means of the hob itself or by means of a mobile telephone, and transferred to a database in an Internet cloud storage facility. From the latter, specific characteristics for this cooking appliance can be downloaded and employed for a temperature-controlled heating of the cooking appliance.

A cooktop appliance includes a cooking surface configured for receipt of a cooking utensil and an induction heating element operable to inductively heat a load with a magnetic field. The induction heating element includes a coil. The cooktop appliance also includes a sensor. The sensor is operable to detect a location and an efficiency of the cooking utensil. The sensor may be positioned between the coil of the induction heating element and the cooking surface and/or may include a plurality of semi-circular loops spaced apart around a circumference of the coil.

A cooking appliance such as a range or stovetop incorporates cooking container sensing for controlling burner ignition and/or triggering events in programmed cooking sequences.
