Benefits of technology

[0019]According to an embodiment, since a fuse function is embedded in a heating element, a plurality of heat sources which generate heat when power is applied are fused in a case in which the plurality of heat sources generate heat at a high temperature higher than or equal to a preset temperature so that a current can be blocked f

Problems solved by technology

Heaters using general nichrome wires have a risk of igniting when overheated.
However, the heater unit using the PTC element as a heating element may not obtain a large amount of heat because there is a limitation in increasing a size of the PTC element.
In addition, in the heater unit using the PTC element, since a conductive carbon mixture, which is a conductor, is coupled to only a part of a heating surface of the PTC element, there are problems in that a temperature distribution for each part of

Abstract

Provided is a heating element having a fuse function. The heating element having a fuse function according to an exemplary embodiment of the present invention includes a plurality of heat sources which generate heat when power is applied, a fuse member of which both end portions are physically connected to two heat sources disposed to be spaced apart from each other by a gap to connect the two heat sources in series and which is fused to electrically disconnect the two heat sources when a temperature is higher than or equal to a preset temperature, and an insulating member which surrounds the plurality of heat sources and the fuse member.
