Description

[Detailed Description of the Invention] The present invention relates to a heater element for wrapping and fixing a heating element.

Conventional heating devices that use heat-generating resistance wire, such as Doostar and hair curlers, are made by wrapping a resistance wire around a heater made of mica board, asbestos board, or a screwdriver, depending on the device. is used.

Those made of mica board or asbestos board can only have a simple structure, and those made of screwdriver have drawbacks such as being heavy and easily damaged.

The present invention solves these drawbacks and provides an ideal heater easily and economically.

The gist of this method is to form a braided sleeve 1 so as to have protrusions 2 on its surface.

The sleeve to be used in this case is one in which a thick weave is woven according to the convex pitch P that is required in advance during braiding, and the required shape is determined, for example, a cylinder, a raft cylinder, or a polygonal cylinder. can be easily closely related by selecting the shape of a shaping cylinder (not shown) to be inserted into the hollow portion 3 during molding to the desired shape.

Further, it has the advantage that it can be made into a plate shape by flattening it as shown in the perspective view shown in FIG.

Since the heater wire obtained in this way has protrusions on the surface, the protrusions act as locking parts when winding the heating wire, preventing the winding from collapsing, and the heating wire can be wound at close intervals. There is also the advantage that even if the wires are not in contact with each other due to misalignment, a uniform heat distribution can be obtained over the entire area.

The third advantage is that because the thick fibers are regularly knitted, the strength of the molded product is high and sufficient strength can be obtained even with a small amount of molding agent.

Furthermore, the fourth advantage is that the molded product can be made as thin as about 9.5 mm, making it extremely lightweight.

The fiber used in this invention is glass fiber.

Heat-resistant materials such as asbestos fibers are commonly used, but organic fibers such as Tetoron fibers may also be used when the required wattage is low.

As the molding agent, for example, a silicone resin, a fluorine resin, or an inorganic paint is used, but in the case of a low wattage, an acrylic resin or other organic paint can be used without any problem.
