Disclosed herein is a cooking appliance. A working coil provided at a lower portion of the cooking appliance. The working coil heats a tray disposed in a cooking compartment in an IH mode. A temperature measurement module, which measures a temperature of the tray in a contact mode, is provided in the center of the working coil. The temperature measurement module includes a module body that is elastically biased upward by a spring. The module body is inserted into the spring and supports upper and lower ends of the spring. When the module body is installed on the working coil, the lower end of the spring is supported by an installation base of the working coil. The module body and the installation base are fastened in a key-to-key groove structure.

Several embodiments include a cooking instrument. The cooking instrument can include a heating system. The heating system can include one or more heating elements capable of emitting wireless energy into the cooking chamber. The cooking instrument can also include a control system. The control system can determine a heating sequence (e.g., logical instructions) to drive the heating system. The control system can then execute the heating sequence. The heating sequence can include an instruction to adjust, based on a trigger event detectable by the control system, the spectral power distribution of wireless waves emitted from a heating element in the heating system.

The heater device is provided with a heater main body, and radiates radiant heat from the heater main body toward an object. The heater main body includes a sheet-like heat generating layer that generates heat and radiates the radiant heat, and a sheet-like heat insulating layer that is disposed on the side opposite to the object of the heat generating layer. The heat insulating layer has a sheet-like first layer having voids and a sheet-like second layer having voids arranged side by side in a thickness direction of the heat insulating layer with respect to the first layer. A porosity of the second layer is higher than that of the first layer.

A heating element for a cooking appliance includes terminals that act as electrically conductive contact points. One or more buses are arranged between the terminals, and connect one or more heating element segments in a zig-zag configuration. The heating element segments are connected in series and are arranged parallel with one another. Each heating element segment includes a plurality of cutouts linked together and having an elliptical shape. The terminals, heating element segments, and buses are a continuous single sheet of conductive material. A method of making the heating element includes forming a pattern into the sheet of conductive material by etching the pattern into the conductive sheet using photolithography.

Provided is a cooker which has a frame forming a side plate, which can be easily manufactured and can reduce manufacturing cost. The cooker includes a cooktop assembly for cooking and directly heating a container in which food is accommodated. The cooktop assembly includes a side plate having at least two frames coupled to each other, and a top plate located at an upper portion of the side plate.

An electromagnetic induction heating cooking appliance may include a heating plate comprising a magnetic substance, a cooking space in which the heating plate is accommodated, an electromagnetic induction heater that supplies an induced current to the heating plate, and a heat emitter that emits heat so as to heat food placed on the heating plate. The electromagnetic induction heater and the heat emitter may be disposed on different sides of the cooking space, respectively. The electromagnetic induction heating cooking appliance may further include a water storage groove that generates steam in the cooking space when water is placed in the water storage groove.

A cooking apparatus is disclosed. The cooking apparatus according to one exemplary embodiment of the present disclosure comprises: an inner wall for forming a cooking chamber; an outer wall for encompassing the inner wall; a microwave generating part for emitting a microwave at a passage, which is a space surrounded by the inner wall and the outer wall; and an absorbing layer absorbing the microwave to be propagated along the passage, so as to emit an infrared ray at the cooking chamber.

A cooking device and a control method thereof is provided which heating a curved area to a higher temperature than a flat area of a cooking area where food is cooked. A cooking apparatus includes a cooking unit having one side in which a first cooking region and a second cooking region distinguished from the first cooking region are provided; a heating unit configured to heat the cooking unit; and a controller configured to control the heating unit to heat the first cooking region to a first temperature and to heat the second cooking region to a second temperature different from the first temperature.

A cooking appliance, system, and method use one or more split-surface-area radiative heating elements and may also use one or more additional heating elements, such as microwave and convection heating elements, to heat or cook food. The radiative heating elements are used in a cooking chamber having an improved geometry. A controller includes features to adaptively learn and adjust cooking recipes based on modifications and user ratings of a particular cooking recipe or based on learning in response to analysis of modifications and user ratings of plural cooking recipes. The controller may learn from ratings of other users of similar cooking appliances via a network connection.
