摘要： An electric heater includes a substrate (an insulating material capable of forming a conductor pattern on a surface of an insulating substrate), a first plane heating element formed on one surface of the substrate, and a second plane heating element formed on one surface of the substrate to be located outside the first plane heating element. The first plane heating element includes a first pattern portion connecting a start point with an end point located in a first zone, a pair of first electrodes located outside the first zone, and a pair of first connectors connecting the first pattern portion with the first electrodes. The second plane heating element includes a second pattern portion located in a second zone surrounding the first zone and connecting a start point with an end point, and at least some of the first connectors are located in the second zone.

摘要： An electric heater includes a substrate; and a plane heating element disposed on one surface of the substrate. The plane heating element includes a pattern portion including a start point and an end point, which are located at an outermost side of the pattern portion, the pattern portion including a plurality of tracks having an arc shape, which are spaced apart from each other and are formed to have a length increasing from an innermost side to the outermost side of the pattern portion, and a plurality of bridges connecting the plurality of tracks in series. The plurality of bridges are formed on both sides of the pattern portion with respect to a reference line passing through a center of the pattern portion, and an innermost gap between the pair of bridges located at the innermost side of the pattern portion is narrower than an outermost gap between a pair of bridges located at the outermost side of the pattern portion.

摘要： An electric heater includes a substrate and an inner plane heating element formed on one surface of the substrate. The inner plane heating element includes an inner pattern portion connecting a start point with an end point. The inner pattern portion includes a first track, a second track located outside the first track and spaced part from the first track, a first bridge connecting the first track with one end of the second track, a third track located outside the second track and spaced apart from the second track, and a second bridge connecting the other end of the second track with the third track. A first gap G1 between the first and second tracks is shorter than a second gap G2 between the second and third tracks along a virtual line crossing the first, second and third tracks and closer to the first bridge than the second bridge.

摘要： An electric heater includes a substrate; and a first plane heating element disposed on one surface of the substrate, in which the first plane heating element includes a first track; a second track spaced apart from the first track; and a third track spaced apart from the second track. At least a portion of the second track is located between the first track and the third track, and the first track and the second track are connected by a first bridge, where the first bridge includes a first outer protrusion protruding toward the third track. The third track is formed with a curved portion which protrudes in an outward direction, and the first outer protrusion faces an inside of the curved portion in the outward direction and is spaced apart from the curved portion.
