Disclosed is an electric range controlling heat power based on properties of a heating target. The electric range may adjust the heat power based on the properties of the heating target, when a user makes a gesture of moving the heating target in a specific direction. A unit decrease amount value of the heat power sequentially decreasing may be set based on the information related to the heating target. The information related to the heating target may include at least one of the weight of the heating target, the size of the bottom surface of the heating target or the property of contents contained in the heating target.

Disclosed is an electric range which provides specific functions without user intervention. The electric range adjusts the heating power if a user enacts a gesture that slides an item to be heated in a first direction. Also, the electric range provides additional functions if a user enacts a gesture that slides an item to be heated in a second direction.

A wireless power transmission apparatus including at least one processor configured to drive a plurality of working coils to transmit power to drive a communication interface of a cooking appliance with which a communication connection has been released when the cooking appliance is moved from a first cooking zone; receive a first wireless communication signal including identification information from the cooking appliance, and drive the working coils to generate respectively corresponding magnetic fields according to a plurality of different power transmission patterns corresponding to a plurality of cooking zones; and output second cooking zone information through an output interface in response to receiving a second wireless communication signal including the identification information regarding the cooking appliance and information regarding the second cooking zone corresponding to one of the plurality of different power transmission patterns detected at a current location of the cooking appliance.

Disclosed is an electric range which provides specific functions according to the gestures of a user. When an object to be heated that is currently being heated is moved to a different spot, the electric range determines in what way the object to be heated has been moved, and provides a specific function corresponding to the determined way of movement.

In order to detect on an induction cooktop whether a cooking vessel with an integrated controller or smart functionality is arranged over an induction heating coil, the induction heating coils emit a short individual code. The latter can be detected and evaluated by the cooking vessel such that the cooking vessel emits a signal corresponding to this code which is received by an external operating means or the induction cooktop to locally associate this cooking vessel with this induction heating coil. Transmission or transfer of energy as a code proceeds at a frequency of at least 50 kHz, wherein a code has a plurality of pulse sequences, each of which has at least two pulses.

Disclosed are an electric range of which heat power is controlled without user intervention, and a control method therefor. The electric range controls heat power by using a gesture in which a user lifts an object to be heated. The electric range comprises a case; a cover plate which is coupled to the upper end of the case and which has an upper surface on which the object to be heated can be arranged; a heating part, which is disposed inside the case, for heating the object to be heated; and a control part for controlling the heating part. The control part controls the heating part so as to reduce the heating power generated by the heating part when the object to be heated, which is heated by the heating part, is lifted from the upper surface of the cover plate.

A temperature sensor assembly for a cooktop appliance can include a plate with a cylindrically-shaped boss, one or more seals located in one or more grooves of the plate, a grommet disk engaged with the bottom surface of the plate, and a cylindrically-shaped grommet in which a cap for a temperature sensor is positioned and is slidable therein.

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.
