The shape of the burner head is changeable, so as to adapt to cooking utensils having different bottom outlines.

A process for the manufacture of a glass-ceramic article exhibiting properties of resistance to scratches, greasy marks, adhesion of dirt and light scattering. The glass-ceramic article includes a surface, the surface arithmetic roughness of which is between 2 μm and 7 μm and the roughness being obtained using a chemical surface treatment. The glass-ceramic article is particularly suitable for use as a cooking surface and/or as surface for the preparation of foodstuffs.

A cooking plate mountable into an opening of a resting surface, in particular of a surface of a kitchen worktop, wherein the cooking plate comprises: a component box for housing functional components of the cooking plate (1), which has a base and side walls, wherein at least one of the side walls is connected to a resting fin that can rest on the resting surface in a mounted state of the cooking plate in the opening, and a positioning device with at least a limiter limiting the minimum distance from the wall to an opening edge in the mounted state of the cooking plate in the opening, where the limiter is adjustable in at least two fixed positions for limiting the minimum distance from the side wall of the component box to the edge of the opening.

A cooktop appliance or griddle assembly may include a cooking platter, a spring-loaded platform, and a sensor body. The cooking platter may define a top surface and a bottom surface. The spring-loaded platform may be mounted below the cooking platter. The sensor body may be attached to the spring-loaded platform in biased conductive engagement with bottom surface.

Device and method are described for operational control of a knob on a stove or range. In some examples, a safety device, a sensor relay device, and method are described for automatically positioning an operational shaft of a burner to an Off position such that the power supplied to the burner is terminated upon the occurrence of a safety event.

A glazing can be used as a constituent element of a heating device or of a fireproof door. The glazing includes a transparent substrate coated with a stack of thin layers including at least one silver-based functional metal layer and an upper protective layer based on zirconium titanium oxide.

A light source module and a cooking appliance including the same may include a light source emitting light toward a glass top plate, a light source guide to accommodate the light source, including a light transmitting path formed in the light source guide, and limit a light irradiation region so as to guide light emitted from the light source to a light display region of the glass to plate through the light transmitting path, and an attachment bracket provided between the light source guide and the glass top plate, the attachment bracket having an optical emission path to allow light to pass from the light transmitting path and the light display region.

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.

A cooking grate includes a peripheral frame defining a periphery of the cooking grate, a plurality of fingers extending from the peripheral frame toward a center of the cooking grate, and a slot formed in the peripheral frame, the slot forming a passageway through the peripheral frame from a lower portion to an upper portion thereof in the vertical direction.
