Title:
面状ヒーターおよび面状ヒーターを備えた面状加熱体
Document Type and Number:
Japanese Patent JP6746388
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a planar heater which can be assembled easily as a planar heating body, and heat generation distribution of which is uniform in the surface direction.SOLUTION: A planar heater 30 includes a planar heating part where one linear PTC heater is folded at 180 degrees alternately by required number of times, and a large number of linear PTC heaters are arranged planarly substantially in parallel with each other in a region 32 excepting the folded part 31, a resin spray layer 33 formed in the region 32 of the planar heating part where the linear PTC heaters are arranged substantially in parallel with each other, and a coating layer 34 by a heat-seal film formed to wrap around the resin spray layer 33. Since the resin spray layer 33 and coating layer 34 exist, break-down or irregular movement of the linear PTC heaters is suppressed, and uniform heat generation distribution is maintained. Furthermore, assembly of the planar heater 30 to the box casing constituting the planar heating body is facilitated.SELECTED DRAWING: Figure 3
