Planar heat producing body 30 is made up of the heating resistance wire that many carbon fibres constitute.Below the preferred 2mm of the thickness of planar heat producing body 30, be more preferably below the 0.8mm.As the example of planar heat producing body 30, for example enumerated the disclosed fiber-reinforced resin formed product of Japanese kokai publication hei 8-207191 communique.Fiber-reinforced resin formed product forms as follows: the two ends of the mesh configuration body that forms at the intersection point of the conducting fibre that engages non-conductive fiber and be made of carbon fibre, connected after conducting fibre and the electrode, carried out stacked the resin molding of insulation usefulness such as the fibre strengthening prepreg sheet material (prepreg sheet) of glass epoxide formations such as (glass epoxy) and polyester film.
Fig. 7 A vertical view that to be electric heating board for floor heating shown in Figure 3 observe from the opposition side of the interarea that is provided with soaking plate.Fig. 7 B is the partial section along the planar heat producing body of the A-A ' line of Fig. 7 A.Fig. 7 B turns upside down and represents.For convenience of description, do not represent to pop wood and heating resistance wire closely among Fig. 7 A.Planar heat producing body 30 possesses and has certain-length, linearly and be parallel to each other the configuration heating resistance wire 32a～32e, 33a～33e, 34a～34e, 35a～35e.In Fig. 7 A, planar heat producing body 30 is consistent with the planar dimension of electric heating board for floor heating 20.Heating resistance wire 32a～35e is clipped by the fibre strengthening prepreg 2,4 of rectangle.Be laminated with resin molding 1 at fibre strengthening prepreg 2, be laminated with soaking plate 24 on it.On fibre strengthening prepreg 4, be laminated with resin molding 5.
The radical that constitutes the heating resistance wire of parallel circuit 41～44 is not particularly limited preferred about 3～12.The number of parallel circuit also is not particularly limited, and 4～8 parallel circuits that preferably are connected in series constitute heater circuit.
In addition, replace heating resistance wire with linearity, electrode 31d, 31e through not being connected with power line 12, the formation of turning back between the two ends of electric heating board for floor heating 20 also can adopt the turn back structure of heating resistance wire self of electrode 31d, 31e is not set.
The centre position that the number of the parallel circuit that links in series connection equates, be to be provided with between parallel circuit 42 and the parallel circuit 43 to become the electrode of central electrical connection section 31b.Therefore, the parallel circuit (group of parallel circuit 41,42, and the group of parallel circuit 43,44) across the both sides of electrode 31b and equates mutually corresponding to the resistance between the end (electrode 31a, 31c) of electrode 31b.
In the electric heating board for floor heating 20 of present embodiment, can be with parallel circuit 41～44 integral body as a series circuit, energising (operation mode 1) between electrode 31a and electrode 31c.In addition, also can be with the group of parallel circuit 41,42 as the energising of the series circuit between electrode 31a, the 31b, meanwhile, with the group of parallel circuit 43,44 as the other series circuit energising (operation mode 2) between electrode 31b, the 31c.Two operation modes can switch with being connected of power supply simply by switching electrode 31b.
The changing method of such operation mode, effective when under different electrical power voltage, using electric heating board for floor heating 20.Because caloric value and voltage is square proportional, so if the supply voltage difference, then the caloric value of electric heating board for floor heating 20 alters a great deal, and this is not preferred.But,, therefore, need only that caloric value can be controlled to be same degree to both supply voltage just passable though the supply voltage difference of country variant roughly can be divided into 100V series and 200V series.
When the resistance value of establishing resistance value between electrode 31a, 31b and the parallel circuit between electrode 31b, 31c was respectively R, the resistance value of the planar heat producing body 30 under operation mode 1 was 2R.Because with respect to voltage V, resistance R, caloric value is passed through V
2Therefore/R tries to achieve, if for 200[V] supply voltage when selecting operation mode 1, caloric value is P=200
2/ 2R=20000/R.On the other hand, in operation mode 2, the circuit of resistance R is the state that two row are arranged in parallel, so the resistance value of planar heat producing body 30 is 1/{ (1/R)+(1/R) }=R/2.If for 100[V] supply voltage when selecting operation mode 2, caloric value is P=100
2/ (R/2)=20000/R, in theory for 100[V] supply voltage and 200[V] supply voltage, can obtain same caloric value.So, be 100[V at the voltage that applies] situation and 200[V] situation under, only by changing the electrode that is connected with power line, just can make the heat of generation equal.
In order to make operation mode 2 become possibility, be necessary electrode 31b is used as central electrical connection section, so electrode 31b is located at, and the same side is favourable mutually with electrode 31a, 31c.Therefore, the quantity of parallel circuit is preferably even number, further for the resistance unanimity of the both sides that make central electrical connection section, the configuration of the heating resistance wire in each parallel circuit and each parallel circuit is that the center is the line symmetry with the center line c that lays direction x extension by central electrical connection section and edge preferably.
Electrode 31a～31e for example is made of tinsels such as copper or aluminium.Be respectively equipped with the connecting portion 36a～36c that is connected with power line 12 at electrode 31a～31c.
With reference to Fig. 7 B, (Fig. 7 B only represents electrode 31b to electrode 31a～31e to form from the mode that simultaneously covers heating resistance wire 32a～35e.Other electrodes are also identical.)。On electrode 31b, be laminated with wire netting 3b respectively.Wire netting 3b is by formations such as metallic fiber, metal fibre interlacement, punch metal (punching metal), expansion alloy, metal mesh belts.When wire netting 3b is connected in electrode 31b at the lead 12a (with reference to Fig. 8) that will be connected with power line 12, has fixing effect as the scolding tin that connects means.
Near the electrode 31b of fibre strengthening prepreg 4 position is formed with through hole 4b for the electrical connection that realizes power line 12 and electrode 31b.Through hole 4b has the diameter about 5～50mm.On fibre strengthening prepreg 4, also be formed with the through hole 5b of the size that comprises through hole 4b in the stacked resin molding 5.
Fig. 8 is used to illustrate the figure that connects the method for attachment of power line to planar heat producing body.At first, so that, planar heat producing body 30 is assembled into electric heating board for floor heating 20 in the through hole 4a that is provided with on the fibre strengthening prepreg 4 mode relative respectively with the through hole 11a that on stiffener 10, is provided with～11c.In addition, only represented through hole 4a, 11a among the figure, though it is below explanation is about through hole 4a, 11a, also identical for through hole 4b, 4c, 11b, 11c.Then, the lead 12a that will be connected with power line 12 is connected in electrode 31a through through hole 4a, 11a by scolding tin 6.Because the anchor effect of the wire netting 3a that is provided with on electrode 31a, scolding tin 6 is firmly attached to electrode 31a.Also can consider not to be provided with electrode 31a, only be connected in heating resistance wire by wire netting 3a, resin infiltrates and the possibility of covering wire netting 3a from fibre strengthening prepreg 4 when being shaped but have.Therefore, electrode 31a is set preferably, in the above the structure of laminated metal net 3a.
Afterwards, by potting resin 7 in the through hole 11a that is provided with on stiffener 10, the lead 12a that will be connected with power line 12 is firmly attached to planar heat producing body 30, can waterproof.As the resin 7 that is filled among the through hole 11a, for example can enumerate thermosetting resins such as epoxy resin, silicone resin, thermoplastic resins such as polypropylene etc.
Then, the configuration pattern to heating resistance wire describes.Fig. 9 is near the partial detailed figure the B portion among this figure of the planar heat producing body shown in Fig. 7 A.Each parallel circuit 41～44, for planar heat producing body 30 at the resistance R i that lays overall with W on the vertical direction y, each parallel circuit 41～44 (wherein, i=41～44), the all-in resistance R (that is, the resistance sum of each parallel circuit 41～44) of heater circuit, be configured in have by
Wi=(Ri/R) * W (formula 1)
Among parallel circuit zone A41～A44 of the width w41～w44 of decision.The overall with W of heater 30 comprises the width of non-setting area 105.
At first, as simple example, consider all identical situation of width w41～w44 of parallel circuit zone A41～A44.At this moment, according to formula (1), the resistance R 41～R44 of parallel circuit 41～44 is all identical.Parallel circuit zone A41 comprises the non-setting area 105 of the heating resistance wire that produces by configuration stack wood 22, yet parallel circuit 41 can't be disposed at non-setting area 105.Therefore, heating resistance wire 32a～32e centralized configuration zone of in the A41 of parallel circuit zone, removing the wide w41 ' of non-setting area 105.That is, the arrangement pitches that heating resistance wire 32a～32e is configured is less than the arrangement pitches at the heating resistance wire 33a～33e of parallel circuit zone A42 setting.Because resistance R 41, the R42 of parallel circuit 41,42 are identical, so the heat that produces at parallel circuit zone A41 equals the heat that produces at parallel circuit zone A42.Equally, the heat that produces at parallel circuit zone A43 equals the heat that produces at parallel circuit zone A44, and the result is all identical at each parallel circuit zone heat that A41～A44 produces.Because width w41～w44 of parallel circuit zone A41～A44 is also all identical, so the average caloric value of the per unit area of parallel circuit zone A41～A44 also equates.Thus, just be that parallel circuit zone A41, A44 comprise the zone that a part of heating resistance wire can't be set, by intensive configuration heating resistance wire, also can dispose heating resistance wire and satisfy formula (1), can make the heating equalization of planar heat producing body 30.
Figure 10 is the configuration pattern that is used to illustrate each heating resistance wire in the parallel circuit, near the B portion of the planar heat producing body shown in Fig. 7 A partial detailed figure.(a11～a45) overlap with non-setting area 105, the heating resistance wire that can't dispose all are configured near the configurable heating resistance wire zone the non-setting area in the heating resistance wire zone.That is, constituting the width that heating resistance wire zone that the part of the heating resistance wire of each parallel circuit is configured has is: the width in the parallel circuit zone of each parallel circuit is divided by the width after the radical of the heating resistance wire of each parallel circuit.Should distribute to the remaining heating resistance wire in the heating resistance wire zone that at least a portion overlaps with non-setting area, be configured near the heating resistance wire zone of non-setting area.Specifically, parallel circuit zone A41 is split into this five part of regional a11～a15, and heating resistance wire 32b～32e is configured in corresponding regional a12～a15.But, because heating resistance wire 32a can not be configured in corresponding regional a11, so near the neighboring region a12 heating resistance wire 32b is disposed at non-setting area 105.For the heating resistance wire 35e of parallel circuit zone A44 too.In this configuration pattern, not only the average caloric value of the per unit area of parallel circuit zone A41～A44 equates, and the average caloric value of the per unit area of the regional a41～a43 among the average caloric value of the per unit area of the regional a13～a15 among the A41 of parallel circuit zone and the parallel circuit zone A44, identical with the average caloric value of parallel circuit zone A42, A43, can make the heating of planar heat producing body 30 realize further homogenising.In addition, owing to can supply with necessary heat from adjacent areas a12, therefore temperature can be reduced being limited in Min. in non-setting area 105.
In addition in the present embodiment, the non-setting area 105 of heating resistance wire is along being provided with at the circumference 28 of laying the both sides that direction x extends, but only also can constitute circumference 28 settings in a side.At this moment, in the zone that non-setting area is not set, heating resistance wire gets final product with the spacing configuration identical with central portion.
Then, under the different situation of the width w41～w44 in parallel circuit zone, at first, calculate resistance R 41～R44 according to formula (1).According to formula (1), resistance R 41～R44 is the proportional value of width w41～w44 with corresponding parallel circuit zone A41～A44, so resistance R 41～R44 is also different.There are two methods can make resistance R 41～R44 different.One is the resistance value diverse ways on each parallel circuit zone A41～A44 that makes the per unit length of each heating resistance wire, specifically, can consider the thickness of the heating resistance wire in each parallel circuit of all or part of change.For example in embodiment described later, the heating resistance wire of 3000 (filament) can be changed to 1000 or 6000 etc. heating resistance wire.
Another method is to make radical diverse ways on each parallel circuit zone A41～A44 of heating resistance wire.Figure 11 be used to illustrate the parallel circuit zone width not simultaneously, the figure of the configuration pattern of the heating resistance wire when changing the radical of heating resistance wire corresponding to the width in parallel circuit zone is near the partial detailed figure of planar heat producing body corresponding the B portion with Fig. 7 A.The ratio of the width w42 of the width w41 of parallel circuit zone A41 and parallel circuit zone A42 is 7: 4, and therefore, according to formula (1), the resistance R 41 of parallel circuit 41 is 7: 4 with the resistance ratio of the resistance R 42 of parallel circuit 42.In order to realize this resistance ratio, as shown in the figure, be provided with the heating resistance wire of four same diameters at parallel circuit zone A41, be provided with seven heating resistance wires with these four same diameters of heating resistance wire at parallel circuit zone A42.
More than can change a kind of saying as follows.That is, when the radical of the heating resistance wire that reduces the parallel circuit zone, the result of resistance and the inversely proportional increase of radical is, according to the width increase in formula (1) parallel circuit zone.And, because the also minimizing to some extent of the radical self of heating resistance wire, so can guarantee the peak width of each bigger heating resistance wire by both resultant effects.Consequently also the area configurations heating resistance wire of non-setting area can comprised.In this configuration pattern, can on regional a11～a14, the b11～b17 of each parallel circuit zone A41～A44, c11～c17, d11～d14 whole, dispose heating resistance wire.
As mentioned above, with non-setting area adjacent areas, be difficult to the equivalent arrangements heating resistance wire sometimes.But in the present embodiment, the radical by at the parallel circuit area decreases heating resistance wire that comprises non-setting area can increase each heating resistance wire and share width, therefore can increase heating resistance wire interval each other.Therefore in this configuration pattern, not only the average caloric value of the per unit area of parallel circuit zone A41～A44 equates, the average caloric value of each regional per unit area in five equilibrium parallel circuit zone also can be all consistent, can make the further homogenising of heating of planar heat producing body 30.
If dwindle the width of stack wood 22, then become easily at regional a11 configuration heating resistance wire 32a, more produce effect.But, just can not dispose under the situation of heating resistance wire 32a at regional a11 at last, as shown in figure 12, by with non-setting area adjacent areas in two heating resistance wires once all are set, also can obtain identical effect.
