A cooking appliance device includes a heating unit having a heating element for heating a cooking chamber in a heating operating state, and a cooking chamber element configured to at least partially bound the cooking chamber. The cooking chamber element has a part region with a surface shape which changes in the heating operating state in response to a thermal expansion of the cooking chamber element. The heating unit includes an adapting element which is arranged at least in part on the cooking chamber element and has in facing relation to the part region a surface which adapts in the heating operating state to the surface shape of the part region.

A cooking appliance includes a door frame that supports a heating part and is coupled to a door such that the heating part is disposed at the door.

Disclosed herein is a cooking appliance including a door formed including a door upper surface part which covers an upper surface of a housing and a door front surface part which is connected to a front side of the door upper surface part and covers a front surface of the housing, wherein an input part is disposed in the door front surface part.

A cooking appliance includes a housing that defines a cavity therein, a door connected to the housing and configured to open and close the cavity, a microwave (MW) heating module configured to emit microwaves into the cavity, and an induction heating (IH) module configured to emit a magnetic field towards the cavity. The IH module includes a working coil that is configured to generate the magnetic field and a thin film that is disposed between the cavity and the working coil.

The present disclosure provides a heating cooker with improved usability. A heating cooker comprising: a heating unit that heats a cooking object; a temperature detector that detects temperature information about the cooking object; a controller that controls the heating unit based on heating conditions including at least a heating temperature and a heating time, and the temperature information; and a communicator that communicates with an external device, wherein the external device receives input information from a user, wherein the communicator transmits the input information received from the external device to the controller, and wherein the controller creates, when the input information is predetermined input information, update information about at least the heating temperature among the heating conditions based on the predetermined input information.

The invention relates to a dental furnace, in particular a high-temperature dental furnace for oxide ceramics such as zirconium dioxide having sintering temperatures of between 1300 and 1850° C., comprising a heating element (10) which is intended to give off heating energy to the firing chamber. It is provided that the heating element (10) comprises at least two heating element sections (48, 50) adjoining one another at a transition area (34) which is not current-carrying and/or which extends away laterally, that the transition area (34) is supported on a position, in particular on the free end, spaced apart from the electrical connections (16, 18) on the dental furnace and carries at least the two adjoining parts of heating element sections (48, 50).

Disclosed is an induction burner ignition system that implements an induction burner located external to the fire pot. The induction burner can be controlled by a controller to start and stop according to a predetermined heating algorithm, and can further provide heat via heat sinks in contact with the induction burner. Because the induction burner is located external to the fire pot, it is easily repairable or replaceable and avoids the harmful atmosphere of the fire pot. The induction burner also provides more uniform heating than conventional hot rod technology to improve the pellet heating process.

Disclosed is an induction range having an automatic double side roasting function. The induction range includes a body having an internal space in which a heating coil portion configured to perform induction heating and a rotating rod configured to provide torque of a motor are formed, an induction-exclusive container which is inserted into and mounted in the body to be tilted from the ground at a first angle and is continuously or intermittently rotatable inside the body by the rotating rod and in which an object to be cooked which is accommodated therein is cooked by induction heat transferred from a side surface of the induction-exclusive container, and a control portion including a recipe memory portion configured to store a plurality of preset recipe modes, a heating coil operation portion configured to control an operation of the heating coil portion, and a motor driving portion configured to control the motor.

An induction heating device includes a first coil that is wound about an axis by a first number of rotations, a second coil that is spaced apart from the first coil in a radial direction and that is disposed radially outward of the first coil, the second coil being wound about the axis by a second number of rotations, and a power supply unit configured to convert alternating current (AC) power and to supply a high-frequency AC to the first coil and to the second coil based on conversion of the AC power. The induction heating device is configured to output a maximum output level in a range from 6500 W to 7500 W based on a ratio between the first number of rotations and the second number of rotations.

Disclosed herein is a cooking appliance. A working coil is 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 receiver coil wirelessly receiving external power is stacked below the working coil. An electromagnetic shielding plate is installed between the working coil and the receiver coil to partition a space in which the two coils are installed. The electromagnetic shielding plate shields an electromagnetic field or electromagnetic waves such that the electromagnetic field or electromagnetic waves in one of the two partitioned spaces does not leak to the other space located across the electromagnetic shielding plate.
