[Detailed description of the invention] [Industrial application field]

A major invention relates to a sheet heating element used for carpets, cushions, etc.

[Conventional technology]

A group of weft yarns in which thin yarns with excellent heat resistance and excellent visibility are mixed and paralleled with thin heat-generating wires with visibility, and a group of weft yarns in which the same fiber yarns as the above-mentioned fiber yarns are intertwined and paralleled. The conductive band portions are arranged in a large scale near both ears, and conductive wires having flexibility and surface conductivity are intertwined with the weft groups to form narrow vertical striped fibers. The planar heating element was developed in 1973.

[4j'] A lead string is absolutely necessary to electrically connect the conductive band part (4)', ! 4) From the standpoint of improving safety by preventing abnormal heat generation when the wire is disconnected at the intermediate part during use, 5) occurrence of partial non-conduction, 2) the auxiliary lead m hn is installed as shown in Figure 5. We also wired the power supply to two locations to provide power. Therefore, in many cases, electric wires coated with insulation were spread out within the sheet body. [Problems to be Solved by the Invention] Since a plurality of electric wires are arranged in the base fabric in this way, in addition to complicating the wiring work, it is also difficult to avoid misalignment between the conductive band and the connection between the electric wires. There is a problem in that the manufacturing cost is high due to the need to perform careful connection work, and in addition, the connection part and the extension part of the electric wire protrude, which makes it feel uncomfortable when using it, and it is difficult to fold it when putting it away. Since there are some difficulties in usage, such as difficulty in use, we have come up with this invention in order to solve the problems of conventional major inventions. It is used as an electrode when manufacturing a sheet heating element using a weaving process instead of wire. By simultaneously weaving a conductive band with the same structure used as a conductive wire in addition to the conductive band, and by specifying the arrangement of the latter conductive band, the related cutting pattern can be standardized, making it possible to create a continuous In addition to making it possible to mass-produce planar heating elements efficiently and easily, it has also been possible to eliminate the conventional defects mentioned above, and it has excellent safety, eliminates discomfort, and has a long life. The invention is intended to contribute to the promotion of spread of planar heating elements.

[Means for Solving Problem 1] According to the present invention, fiber yarns having heat resistance and electrical insulation properties are arranged in parallel along both ends of the warp. For a warp group formed by arranging narrow longitudinal conductive bands consisting of parallel conductive wires having flexibility and surface conductivity,
A narrow transverse conductive band made of parallel conductive wires is arranged at a predetermined pitch on a weft yarn in which fiber yarns having heat resistance and electrical insulation properties and thin heat generating wires having flexibility are arranged in parallel. It is a planar heating element made of intersecting weft yarn groups, and has flexibility as a whole. The great invention also provides that, in the original fabric for the heating element, a vertical conductive band is extended from one edge in parallel to the side on the same side of each of the horizontal conductive band portions, and a vertical conductive band is formed as an electrode close to the edge. After crossing the horizontal conductive band by extending it parallel to the side and bending just before the vertical conductive band close to the other ear to cross the horizontal conductive band, The raw fabric for the heating element is sequentially cut by a series of cutting lines extending along the sides and crossing the vertical conductive bands to reach the ears, and the horizontal conductive bands are cut into 10,000 pieces of the vertical conductive bands. Furthermore, the second invention of the present invention is characterized in that the vertical conductive band part formed in the form of narrow vertical stripes is connected to one ear. It is obtained by cutting from a raw material for a heating element, in which one strip is arranged along the edge and two strips are arranged close to each other along the other edge,
In this case, the cutting line is a horizontal line, and a single vertical conductive band serving as an electrode in one ear is extended from the adjacent tenth ear in parallel to the same side of each horizontal conductive band; 1
Of the two longitudinal conductive strips extending parallel to the side sides and extending across the longitudinal conductive strips, one of the two longitudinal conductive strips located close to each other acts as an electrode. After bending just before crossing the horizontal conductive band, extend it along the opposite side of the horizontal conductive band and cross the two vertical conductive bands to reach the ears. formed into a series of lines,
By sequentially cutting along this cutting line, the horizontal conductive band is electrically connected to one vertical conductive band near the ear of the bittern, and the two are close to each other at the other ear. It is characterized by a structure in which the longitudinal conductive band portions of the strips are electrically connected to each other.

[Effect 1] According to the present invention having the configuration described above, by sequentially cutting the raw fabric for a heating element that is continuously woven along the cutting line with a predetermined linear shape, regular-shaped sheet heating elements can be mass-produced, and It is possible to use the horizontal conductive band as a conducting wire for supplying current to the vertical conductive band as an electrode provided along the ear. Among the two longitudinal conductive bands, the inner vertical conductive band serves as an electrode, and the outer vertical conductive band adjacent to the inner vertical conductive band is used as a current-carrying conductor for power supply. In this way, the conductor wire can be installed at the same time in the manufacturing process by weaving the planar heating element, and since it is flat and installed within the woven structure, it has high mechanical strength and causes a sense of discomfort. Not at all. [Embodiment 1] Hereinafter, one embodiment of the present invention will be described in detail based on the accompanying drawings. In FIGS. 1 and 3, [11] is a raw fabric for heating elements (hereinafter abbreviated as raw fabric), which is continuously woven in the form of a sheet having a predetermined width. Raw fabric for opening (1) Cotton yarn, which has heat resistance and electrical insulation properties,
A fiber yarn such as polyamide yarn (6) and a thin flexible heat-generating wire (8) For example, a wire with a conductive coating such as carbon on the outer periphery of a flexible, heat-resistant core wire. A group of weft threads arranged in a mixed and parallel manner [first

) forms a woven fabric comprising a group of warp yarns that are intertwined and parallel to the group of weft yarns. In addition, various methods of weaving can be used, such as arranging the thin threads (6) and the heat-generating wires (8) alternately, one by one, so that multiple rows of one side are weaved and then multiple rows of the other. - The above raw fabric [11] further includes a transverse conductive band part f3 in the weft group.
- Mature conductive band in the warp group

Regarding the aspect, the horizontal conductive band part

Similar to [3], conductive wire (

By changing the supply system in the weaving process of the original fabric + 11, it is possible to simultaneously weave and kata, without bothering with any separate process. Cutting lines [5] of a predetermined pattern are attached to the raw fabric (1) woven in this way, and the cutting lines (5)

Then, bring it to just before it touches the second vertical conductive band part (4) [(I:Ill~(c)]), then bend it from there and cross the horizontal conductive band part (31) [( c) to)],

) and (4) to reach the ear and form a series of vertical and horizontal lines consisting of [ni] to (e). The single piece obtained by cutting the pattern along the cutting line (51) has the shape as shown in Figures 2 and 4, and the lower right corner is cut off from the original square shape. 10,000, the lower left corner has the same shape as this cut-off 'f: the square has a shape that protrudes to the side, and the controller (10J) for controlling the energization is attached to the cut-off part of the lower right corner.
By folding the protruding part at the lower left corner along the folding lines (C) to (F), a square heating element can be obtained. This is clearly shown in Figures 2 and 4. Like a horizontal conductive band! +31 and the first vertical conductive band part (4) are electrically connected with almost no contact resistance because the conductive wires [9] are intertwined with each other at the intersection at the upper right corner. In the example shown in Figure 4, the second and third vertical conductive band parts (4) and (4) both have the horizontal conductive band part [3] left uncut at the folded part at the left end in a bridging state. They are electrically connected with almost no contact resistance. Therefore, the first vertical conductive band part [4] and the second vertical conductive band part (4)
) are connected in parallel to the voltage terminal in the controller +101 and the first vertical conductive band (4), that is, the horizontal conductive band part]5) when used as an electrode connected to the end of 81 On the other hand, the third vertical conductive band part (4) in the example shown in FIG. ] functions as a conductive wire for connecting the voltage terminal in the controller [101 and the farthest end of the second longitudinal guiding turtle band (4). However, since the rightmost end of the second vertical conductive band (4) is directly connected to the voltage terminal within the controller (10), the third vertical conductive band (4) is directly connected to the voltage terminal within the controller (10). This means that it functions to supply power to two points in the same way as the conventional auxiliary lead wire.In addition, in each of the embodiments shown in Figs. A first narrow strip adjacent to the horizontal conductive band [3] at a position opposite to the cutting line (5) of 131.
Weave the weft yarns of zone +II+ in the above-mentioned fiber yarn (61 thread) so that no heat-generating strands (3) are present, and the transverse conductive band portion [3] is directly connected to the above-mentioned heat-generating strands (8). Further, in the embodiment according to the second invention shown in FIGS. 3 and 4, the first band [+1
In addition to 1, there is a horizontal conductive band portion (3). [The second band (Ill) weft located in the middle between 31 and 1st band (Ill
In the same way, the fiber yarn (6) alone is used to perform an a-shape such that the heating element wire (81) is not present, and the sheet heating element (21) after cutting is cut into the second zone (11) connected to the latter second zone (11). By cutting out band 021 of the vertical conductive band portion (4), it is possible to use three types of heat generation: full heating, right half heating, and left half heating. It will function as a conductor for the negative electrode. Also, the band between the second and third vertical conductive bands (i4).(4) may be removed later, and the band (1υ, (river) Of course, there is no problem even if the auxiliary lead is removed as a separate component in a separate process in the weaving process of the sheet heating element. It is possible to simultaneously provide the wires at the required locations by weaving, and since the wires are provided in a flat textured ore with the same structure as the conductive band used as an electrode, it has excellent mechanical strength and It is possible to obtain a high-quality product without the "lumpy" discomfort caused by heat.Since the planar heating element is completed in one step using the rough MTT process, troublesome steps such as soldering and wiring are eliminated. There is also the advantage that it can be omitted, streamlining and speeding up production.
