An embodiment of an electric range may include multiple ferrite modules disposed on an upper supporter, disposed beneath multiple coil substrates, and disposed at positions corresponding to the coil substrates. Each of the ferrite modules includes multiple ferrite cores, and the lateral ends of working coils may be disposed at the same positions as or inside the lateral ends of the ferrite cores. The working coils and the ferrite cores may have a rectangular outer shape. A first length defined as the length between a pair of parallel outer sides of the ferrite cores may be equal to or longer than a second length defined as the length between a pair of parallel outer sides of the working coils.

Disclosed herein is a cooking appliance. The cooking appliance includes a supporter disposed in an accommodation space surrounded by a case and a top plate, and a lighting module supported by the supporter and configured to emit light toward the top plate, and at least a portion of the lighting module is disposed between a bottom portion of the case and the supporter.

Disclosed herein is a cooking appliance. The cooking appliance includes a coil module including at least one of a heating coil and a sensing coil, and a lighting part configured to implement lighting, and the coil module and the lighting part are integrally formed.

According to the present invention, disclosed is a coil assembly provided in an induction heating cooking device. The coil assembly comprises: a plurality of heating coil layers having formed therein a plurality of heating coils; and a wiring layer stacked on top of the plurality of heating coil layers and having formed therein heating coil wirings. The plurality of heating coil layers and the wiring layer are formed on the same substrate. According to the present invention, a container may be detected through the heating coils, without using a detection coil, by detecting a change in impedance of the heating coils.

The present invention provides a coil assembly provided in an induction heating cooking device. The coil assembly has a structure in which a plurality of heating coil wires and a plurality of sensing coil wires are disposed on the same layer as one of a plurality of sensing coil layers in which a plurality of sensing coils are disposed. Accordingly, the connection between the heating coils can be optimized, and the thickness of the heating coil layer of the coil assembly can be reduced.

One embodiment of an electric range may include a plurality of ferrite modules that are disposed on the upper part of a supporter and below a coil portion, and arranged at positions corresponding to a plurality of coil substrates, respectively. The ferrite modules may comprise: a ferrite core; and a core fixing part that is coupled to the supporter and formed by insert injection molding with the ferrite core, and that fixes the ferrite core. The ferrite cores may be formed as one of a first type, formed by combining ferrites having different surface areas, or a second type, in which a plurality of ferrites having the same shape are radially arranged with respect to the center of the ferrite module.

A coil assembly is disclosed. The coil assembly comprises a plurality of heating portions disposed on a substrate. The plurality of heating portions are formed in a rotating pattern and electrically connected to each other through at least two layers. The pattern of the plurality of heating portions forms a plurality of spirals in one layer, inter-spiral regions are formed between the plurality of spirals, and at least one sensing coil is disposed in the inter-spiral regions of the other layer. Accordingly, a space for a plurality of sensing coils and a temperature sensor may be ensured.

An electric range of one embodiment comprises: an upper supporter accommodated in a case; and a lower supporter, which is disposed below the upper supporter, is accommodated in the case and supports the upper supporter, wherein the upper supporter includes a first support part protruding from the lower surface thereof, and the lower supporter can include a second support part that protrudes from the upper surface thereof and is coupled to the first support part. The first support part can include: a protruding part protruding from the upper supporter; and a linear recessed part which is formed by a recessed portion of the protruding part, and of which both sides are open.

Proposed is a movable display device for outputting video and audio, the movable display device may comprise: a transceiver which transmits data to and receives data from a mobile device by wire or wirelessly; a display which includes a touch screen and outputs video data or a user interface for a control command of audio data; a speaker which outputs the audio data; and a controller, wherein the controller receives a connection partner scan initiation request from a first mobile device, initiates a connection partner scan according to the received scan initiation request, and establishes a connection to a second mobile device in a first wireless communication manner according to the connection partner scan, and the connection partner scan initiation request is triggered by the second mobile device.

The present invention relates to a heating coil assembly, a home appliance having same, and a manufacturing method therefor. The present invention comprises a heating coil formed by means of a plurality of vertically stacked layers of conductors, wherein the horizontal outer shape of the heating coil is polygonal. Accordingly, the increasing of the horizontal size of the heating coil is suppressed, while the pattern cross-sectional area per turn of the heating coil is increased, and thus the increasing of the temperature of the heating coil may be effectively suppressed.

It relates to a cooking appliance in which it is possible to prevent deterioration in space utilization by forming a through hole, into which a temperature sensor can be at least partially inserted and coupled, on a coil circuit board module in which a working coil pattern is formed, while enabling the temperature sensor to be effectively installed without securing a separate installation space for the temperature sensor.
