Abstract

The invention relates to a heater being connected with a blower, or the like, to deliver high-temperature hot air, and an insulator being provided in the heater. A planar insulator segment is provided with a large number of gas conduction holes (10, 10, ) and provided, at the circumferential edge part thereof, with inserting parts (12a, 12b) for securing the insulator segment and wiring an electrode. The insulator is formed by laying a plurality of sheets of the insulator segment in the air supply direction. Positions of the gas conduction holes (10, 10, ) of adjacent segments are shifted slightly while the sheets are laid in layers and the inserting parts (12a, 12b) for securing and wiring the electrode are arranged at an identical position. Between adjacent insulator segments where the positions of the gas conduction holes are shifted, a frame-like spacer insulator consisting only of a circumferential part where the inserting part (12c) for securing and wiring the electrode is provided at the same position as these insulator segments is arranged thus constituting a set of insulators for electric heating wire. When a nichrome wire is wired in the gas conduction hole of the set of insulators for electric heating wire, the nichrome wire is twisted by each insulator segment and held and secured surely.

Description

technical field [0001] The present invention relates to a heater connected to a blower etc. to generate high-temperature hot air, and an insulator for supporting an electric heating wire such as a nickel-chromium heat-resistant alloy wire wired in the heater. Background technique [0002] in the attached Figure 10 with Figure 11 Table shows the existing this insulator and heater. Figure 10 It is a perspective explanatory drawing of an insulator, Figure 11 It is a side view transparent explanatory diagram of the heater. [0003] Figure 10 The shown insulator 50 is a so-called Lencon insulator having a cylindrical shape, and a plurality of through holes 52, 52... Wait for the heating wire. [0004] The blast gas flows in the axial direction (gas flow direction) D, passes through the insides of the respective through-holes 52 and is heated. On the inner wall surface of each through-hole 52, no protrusions, protrusions, etc. for supporting the nichrome wire are provided...
