A heating and cooking apparatus is provided that can produce a place for all-participating-type cooking. The electric griddle 100 mainly includes an iron plate section 110 having a high thermal conductivity, a glass section 120 having a low thermal conductivity, a heating material 130 as a heat source, a heat insulating mechanism 140, and an outer frame 150. On the glass section 120, it is possible to place dishes and bowls on which food ingredients and the like can be placed in the glass part 120, and to place food ingredients there directly. Thus, it is possible to prevent food ingredients and the like from being placed only in the hands of a specific person, to realize a situation which many people can easily cook, and to produce a place for all-participating-type cooking.

A tabletop cooking assembly for preparing foods thereon comprises a cooking element having a cooking area and a vent disposed peripherally to one side of the cooking element defining an aperture for receiving smoke from the cooking element. The assembly includes a first exhaust duct, a filter assembly, an electrostatic precipitator, and a high velocity blower. The first exhaust duct is substantially unobstructed and in fluid communication with the vent for directing smoke away from the cooking element. The high velocity blower is in fluid communication with the first exhaust duct and the filter assembly for drawing smoke from the cooking element through the vent. The heating system includes a retaining plate, a plurality of heating strips, and an insulating material. The heating strips are disposed between the retaining plate and the heating surface to heat the cooking area for preparing foods thereon.

A griddle plate suspension assembly having a housing, a griddle plate, a heating element arranged in the housing, a fastener connecting the housing with the griddle plate, and an elastic part pushing the heating element to the griddle plate. The griddle plate suspension assembly enables the griddle plate to be fixed relative to the location of the housing through the fastener, then enables the heating element to be fit to the griddle plate through the elastic extruding of the elastic part. In that way, heat generated by the heating element may be delivered to the griddle plate quickly and uniformly, thereby enabling quick and efficient increase in temperature of the griddle plate. The efficient heat conduction between the heating element and the griddle plate may effectively save the energy needed for baking the food.

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.

An isothermal cooking plate assembly is formed from a first plate of high thermal conductivity material having a back surface and an oppositely disposed top cooking surface. One or more heater circuit assemblies are disposed on the first plate back surface for forming a composite having a back surface. A controller is in electrical connection with the heater circuit assemblies for controlling temperature of the first plate of high thermal conductivity material. The first plate can be aluminum Type 1100 or aluminum Type 6061. The first plate can be a laminate formed from a clad bottom metal layer and clad top cooking surface metal layer, where the clad layers formed from the same material and having about the same thickness. The clad material can be austenitic stainless steel. A second plate of low thermal conductivity material can be attached to the composite back surface of first plate.

An apparatus for cooking food products is provided. The apparatus includes at least one heating plate having a surface provided with alternate crests and troughs. The apparatus further comprises a fixing system adapted to detachably fix a corrugated protective plate, having a non-stick face, to said heating plate. The corrugated protective plate has a first and a second corrugated edge and alternate crests and troughs extending from the first to the second corrugated edge and adapted to match the alternate crests and troughs of the heating plate when the corrugated protective plate is fixed to the heating plate. Said fixing system comprises fixing elements adapted to exert a force on corresponding portions of the protective plate close to the first or the second corrugated edge so as to push the protective plate against the heating plate.

A wirelessly operable cooking appliance for cooking food products includes a wireless communication device. A computing device, such as a smartphone, can wirelessly communicate with the cooking appliance to control and monitor the cooking appliance.

Several embodiments include a cooking appliance/instrument (e.g., oven). The cooking instrument can draw an alternating current (AC) power and generate a maximum available power for a heating system of the cooking instrument via a power component that converts the drawn AC power. The cooking instrument can then directionally heat each of different zones in a cooking chamber of the cooking instrument in sequence using one or more heating elements of the heating system on at least one side of the cooking chamber such that each step in the sequence utilizes the maximum available power for the heating system.

An electric roasting pan according to the present invention comprises: a roasting pan; a heating layer being in surface contact with the roasting pan and comprising a carbon nanotube and a silicone-based adhesive; and an electrode in contact with the heating layer. The electric roasting pan has excellent thermal efficiency thanks to the minimal heat loss thereof, can reach a target temperature within a short time to reduce a preheating time, and affords excellent cooking quality. Furthermore, the electric roasting pan can substantially prevent the occurrence of temperature deviation across the area of the roasting pan during a temperature increase and is of high durability and safety.
