A method for estimating a temperature measurement of an item of cookware being heated is provided. The method includes (1) placing a cookware item containing water, on a cooking plate; (2) powering an electric heating circuit with a first power for a first time interval to heat the cookware item as far as the water contained therein boils, wherein said first time interval is determined so as said temperature sensor senses a first steady state temperature value; (3) powering said electric heating circuit with a second power for a second time interval to heat the cookware item to keep boiling the water contained therein, wherein said second time interval is determined so as said temperature sensor attains a second steady state temperature value; and (4) determining, as a function of said first steady state temperature value and of said second steady state temperature value, an induction cooktop gain.

An induction well includes a tank configured to store a substance, a first induction coil positioned around a first portion of the tank, a second induction coil positioned around a second portion of the tank, and a single power inverter coupled in parallel with the first induction coil and the second induction coil.

An apparatus is disclosed. The apparatus includes a heater comprising a heating element having a region that does not contain a surface heating portion. The apparatus further includes a thermostat positioned in the region. The thermostat includes a contact surface disposed to make contact with an object placed on the surface heating portion. The thermostat includes a switch configured to prevent a current from conducting through the heating element when the contact surface experiences a temperature equal to or greater than a temperature limit. The apparatus further includes a medallion coupled to the thermostat and positioned below a top surface of the heating element, the medallion comprising an aperture shaped to allow the contact surface to extend through the aperture to make contact with the object. The apparatus includes an urging element configured to provide vertical movement of the medallion in response to a downward force applied from the object.

A temperature-regulating appliance includes a top portion, a base, a temperature sensor, and a mounting adapter. The top portion has an upper surface and a lower surface. The base includes a housing defining an internal compartment and a thermal element disposed within the internal compartment of the housing. The temperature sensor is positioned outside of the internal compartment, between the housing and the lower surface of the top portion. The mounting adapter extends between the top portion and the housing. The mounting adapter detachably couples the base to the top portion.

An induction cooking system in accordance with the principals of the present invention includes an induction cooking appliance and custom cookware. The induction cooking appliance includes a cooktop surface, an induction heating system contained below the cooktop surface, and a temperature sensor. The temperature sensor sensing temperature above the cooktop surface. The induction heating system includes a coil positioned immediately below the cooktop surface. The coil is configured to produce an electromagnetic field when the coil is energized. The custom cookware is configured to be placed on the cooktop surface above the coil. The custom cookware includes an inner shell and an outer shell. The inner shell is comprised of a metallic material to heat a food material. The outer shell is comprised of a thermally insulative material that is substantially transparent to magnetic flux. The outer shell includes an underside configured to rest on the cooktop surface above the coil during cooking. The underside defines a thermal-insulation aperture through which the temperature sensor extends temperature sensing above the cooktop surface to the inner shell.

An induction cooker includes a top plate on which a cooking container is placed; a heating coil placed below the top plate and that heats the cooking container; an infrared sensor placed below the heating coil and that detects infrared radiation emitted from the cooking container; a sensor casing that houses the infrared sensor; and a magnetic path forming member placed on a top face of the sensor casing. The magnetic path forming member guides magnetic flux passing above the infrared sensor by being generated from the heating coil.

An infrared emitter includes a first refractory layer of a first refractory material, a coiled wire disposed over the first refractory material, and a second refractory layer of a second refractory material, and a portion of the second refractory layer is disposed within a void of the coiled wire.

Autonomous hydraulic unit comprising a liquid inlet (1); a flow meter (2) which is jointly attached to an inlet (3) of a compression chamber (4) of a pump (5) where a piston (6) injects the compressed liquid through a nozzle (7) into a heating chamber (8).

A plastic body (9) integrates in one piece the compression chamber (4), a self-priming valve (10) and a safety valve (11). A heating element (12) contained within a body (9) determines with a disk (14) the heating chamber (8) where the temperature of the liquid injected by the piston (6) is raised in its passage towards the outlet (13).

Induction hob with boiling detection and induction energy control, method for heating food with an induction hob and computer program product

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).

A temperature-regulating unit includes a base, a resonant tank, and a controller. The base is configured to support a pan. The resonant tank includes a coil and a capacitor. The resonant tank has a resonant frequency that is affected by a material of the pan and a temperature of the pan. The controller is configured to receive a temperature setting, monitor the resonant frequency, determine the material of the pan based on the resonant frequency, determine the temperature of the pan based on the resonant frequency, and adaptively control a thermal element based on the temperature of the pan, the material of the pan, and the temperature setting.
