FIG. 7 is an assembly diagram of the present invention in use. Amendment January 28, 1980 The name of the invention is amended as follows. ■Name of the invention Utility model registration for a hot air generator for heating using a household electric fan The scope of the claim and the brief description of the drawings are amended as follows.・O Utility Model Registration Claims As detailed in the detailed explanation of the invention, the wire mesh flange surface 1 on the main body side and the front wire mesh of the protective kettle mesh for danger prevention on both the front and rear sides for rotating the electric fan shown in Figure 1 of the attached drawing. Between the flange surface 2, as shown in FIGS. 2, 3, 4, and 7,
A) A cylindrical tube made of aluminum with a thickness of 1 mm and a length of 10 mm, which has 7 flange surfaces with the same outer diameter as these flange surfaces on both end surfaces, is inserted between 1 and 2, and each flange surface is 1
゜Make them face each other in the order of 4.5.2 and connect them to each other with clasps 3. In addition, on the inner surface of this metal tube, almost in the center, is an American product with the trade name 1NEXTEL. Ceramic long fiber called - usable temperature 1200
It is as high as 6C, and its tensile strength is as strong as 175ko/m2 (-
One chemical composition that also has excellent high-temperature electrical insulation properties is A1□Q164%, 820114%, 5iO2
A braid made of 24% fiber with an average diameter of 3 mm is stretched in a mesh shape as shown in 6, and the wire spacing is made as small as possible along the mesh, and the wire density is increased over the entire surface of the mesh. A nichrome wire wound spirally over a wide area is wound around the fibers so as to weave through the fiber mesh and wired to form the heat source zone of the electric heater, and both ends of the wired nichrome wire 7 are made of aluminum, which is a good conductor. A highly flexible 1 Nextel sleeve is used as an electrical insulating material at the contact point, and it is connected to the changeover switch 8 and connected to the conductive wire B. - The aluminum cylindrical tube produced in this way is connected to a fan as shown in Figure 17 (1) A household fan is characterized in that it is connected to an electric fan and energized to warm the air from the fan and supply it for heating purposes. Warm air generator for heating used. Brief explanation of the drawings Figure 1 is an external view of a commercially available household electric fan, and A indicates the conductive wire for the electric fan. 1 is the flange surface of the metal cape 7 on the side of the fan body, and 2 is the flange surface of the fan body. The presence of the front wire mesh 7972 surface is shown. Figures 2, 3, and 4 show the main body of the present invention - a cylindrical tube body made of aluminum with 7 rungs on both end faces; Figure 2 is a front view; Fig. 3 is a longitudinal sectional view of the diameter, and Fig. 4 is a perspective view. 3 shows the stopper on the flange surface, 4 and 5 show the presence of the respective surfaces of the flange faces at both ends. B shows the conductive wire on the heater side. 6 indicates the presence of a ceramic fiber mesh, 7 indicates the presence of nichrome wire wiring. 8 indicates the presence of a rotary changeover switch connected to the nichrome wire wiring. Figures 5 and 6 show hot air generation. This is a fastener that connects the device to the wire mesh flange surface on the fan body side. A is the front view, the mouth is the rear view, C is the longitudinal cross-sectional view of the center part, and No. 7
The figure is a longitudinal sectional view showing how to attach the hot air generator to an electric fan.

Claims (1)

[Scope of utility model registration request] As will be explained in detail in the detailed description of the invention, between the main body side wire mesh flange surface 1 and the front wire mesh flange surface 2 of the safety wire mesh on the front and rear surfaces of the rotary fan shown in FIG. As shown in Fig. 2, Fig. 3, Fig. 4, and Fig. 7, an aluminum plate with a thickness of 1 mm and a length of 10 mm (1 mm) has flange surfaces with the same outer diameter as these flange surfaces on both end surfaces. Insert a cylindrical tube between 1 and 2, and place the respective flange surfaces facing each other in the order of 1° 4, 5.
Connect with. The inner surface of the almost central part of this metal tube is made of American-made ceramic long fibers with the trade name 1NEXTELYO, which can be used continuously at a high temperature of 1200°C and has a tensile strength of 175kg/rrrm2.
In addition, chemical compositions that have excellent high-temperature electrical insulation properties include A1□0364%, B20314%, and SiO□2.
4% fibers woven into a braided cord with an average diameter of 3 mm are stretched into a mesh as shown in 6, and along the mesh, the wiring spacing is as small as possible, and the wires are spirally distributed over a wide area with high density over the entire surface of the mesh. A nichrome wire wound into a shape is wound around the fibers so as to sew through the fiber mesh, and then wired in parallel to form a heat source zone for an electric heater.
