An electric resistance heating coil assembly includes a spiral wound sheathed heating element having a first coil section and a second coil section. A bimetallic thermostat is connected in series between the first and second coil sections of the spiral wound sheathed heating element. The bimetallic thermostat is spring loaded such that a distal end of the bimetallic thermostat is urged away from a top surface of the spiral wound sheathed heating element. The electric resistance heating coil assembly also includes a shroud cover and a heat transfer disk.

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.

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 heating circuit includes: an inverter circuit, a heating element, a detection element, a first power supply and a second power supply. The first power supply, the heating element and the inverter circuit form a first loop; the second power supply, the detection element and the heating element form a second loop; the first power supply supplies power to the heating element by means of the first loop, and the heating element generates heat on the basis of the power supply of the first power supply; and the second power supply supplies power to the heating element and the detection element by means of the second loop.

A cooking appliance includes a cooktop having a cooking zone with at least one heating element beneath the cooktop in the cooking zone, a temperature sensor that detects the temperature of the cooking zone, and a controller. The controller executes a temperature-protect mode upon receiving an indication of a presence of a temperature-sensitive component on the surface of the cooktop by adjusting power supplied to the heating element in response to a detected temperature of the cooking zone approaching, meeting or exceeding a threshold temperature in order to ensure that the detected temperature does not exceed the threshold temperature beyond a predetermined degree and/or for a predetermined period of time. The threshold temperature is predetermined to be one that will not damage the temperature-sensitive component.

The present invention relates to a household appliance (1), in particular to a cooking hob, which comprises or is connected to an acceleration detection and/or measuring means (11) and a control unit (23) for controlling operating processes. The acceleration detection and/or measuring means (11), which may be an acceleration sensor and particularly a gravity sensor, is adapted for a detection of an acceleration of a section or a reference point of a wall or a panel (3) of the household appliance (1). The household appliance (1) may comprise a user interface (9) for providing information to a user, particularly status information, and/or for receiving input, particularly of control commands or data input, from the user. The acceleration detection and/or measuring means (11) is connected to the control unit (23) and/or, if applicable, to the user interface (9) for an exchange of data, and forms a trigger element for the control unit (23) and/or, if applicable, for the user interface (9). Further, the acceleration detection and/or measuring means (11) is adapted to provide a trigger signal for a control of a function and/or an operating process in the household appliance (1). Further, the present invention also relates to a method for controlling a household appliance (1), in particular a cooking hob. According to the invention, a function and/or an operating process in or of the household appliance (1) is triggered by an acceleration detection and/or measuring means (11), particularly by an acceleration sensor, more particularly by a gravity sensor, as a result of a detection of an acceleration of a section or a reference point of a wall or a panel (3) of the household appliance (1).

A cooking system includes a placement unit which has a food-holding element and a heating unit for heating the food-holding element. An induction unit provides in at least one operating state an amount of heating energy for inductively heating the food-holding element. The heating unit includes a heating element which is different from an induction heating element and is provided for heating the food-holding element.

We have invented a new, original, and ornamental design for a heater unit. The following is a specification of the heater unit, reference being had to the accompanying drawings, which form a part hereof.

A heater for a stovetop heater unit is disclosed. The heater may reduce false detections of an overheat condition, minimize an impact of radiative heat from a heating element of the heater on temperature measurements of the heater, and accurately measure a temperature of an object placed on the heater. Thus, the heater may reduce an amount of time required to heat an object placed on the heater.

A cooktop appliance and heating element, as provided herein may define a heating zone having a thermostat positioned therein. The thermostat may include a base, a bimetallic disk, and a conductive spring. The base may extend axially between a first end and a second end. The bimetallic disk may be disposed within the base. The conductive spring may be disposed within the base in biased engagement with the bimetallic disk to motivate the bimetallic disk towards the first end within the base. The conductive spring may include a first layer and a second layer. The first layer may extend from a contact end proximal to the bimetallic disk to a joinder end connected to the first terminal. The second layer may extend from a biasing end proximal to the bimetallic disk to a secured end fixed within the base.
