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.

There is provided a substrate fixing device. The substrate fixing device includes: a base plate; and an electrostatic chuck that is fixed to the base plate and configured to adsorb a subject by electrostatic force. The electrostatic chuck includes: an adsorptive layer configured to adsorb and retain the subject; and a heater layer that is provided between the adsorptive layer and the base plate and configured to heat the subject retrained by the adsorptive layer. A thickness of the heater layer is uniform over an entire area of the heater layer.

A cooktop for a cooking appliance includes a cooking panel that has a first edge. A support feature is coupled to the cooking panel proximate the first edge. The cooking panel is disposed on the support feature. The support feature and the cooking panel define a cavity. A human-machine interface is coupled to an underside of the cooking panel. The human-machine interface is disposed within the cavity and adjacent to the support feature. A magnet assembly is coupled to the cooking panel and the human-machine interface. The magnet assembly is configured to retain the human-machine interface in a selected position on the underside of the cooking panel.

Systems and methods are provided for radiant heating by PTC radiant patches. A radiant heating system for warming an occupant of an enclosed space includes patches to radiate heat into the enclosed space toward the occupant. A power supply supplies electric power to the patches. A controller controls the electric power supplied to the patches based on a temperature in the enclosed space and locations of the patches within the enclosed space.

An induction heating cooking apparatus includes a glass provided such that a cooking container is disposed on an upper surface thereof and a side surface thereof is exposed to the outside. The induction heating cooking apparatus also includes an operating coil positioned below the glass to inductively heat the cooking container by generating a magnetic field. The side surface includes a first surface extending from the upper surface of the glass and having a first curvature. The side surface also includes a second surface extending from the first surface and having a second curvature different from the first curvature. The side surface further includes a third surface extending from the second surface to a lower surface of the glass and having a third curvature different from the first curvature and the second curvature.
