Description

The anti-fog filter of heater and manufacture method thereof and outfit heater

The present invention relates to by having the PTC(positive temperature coefficient) the porcelain semiconductor as barium titanate the series heater and the manufacture method thereof that form, that can in many fields such as constent temperature heater, local heater, use of characteristic.A kind ofly be equipped with this heater and be arranged in many wet places such as bathroom but also relate to, prevented that by the heating work of above-mentioned heater the anti-fog filter that mist reveals from appearring in the mirror surface.

Be equipped with the heater of the tabular heater of forming by positive temperature coefficient thermis known already up to now.Positive temperature coefficient thermis is the heater that ptc characteristics is arranged, and it is by the material that ptc characteristics will be arranged, and for example barium titanate etc. is formed as the ceramic semiconductors of primary raw material.Positive temperature coefficient thermis has such characteristic, promptly from room temperature to Curie temperature Tc(resistance cataclysm temperature) resistance is very low, in case surpass Curie temperature, resistance value just sharply increases.Because this characteristic, in above-mentioned heater, add voltage after, flow through very big electric current at first because the temperature low resistance is little, the result sharply rises temperature.Sharply increase then above-mentioned heater reach uniform temperature when above in case because temperature surpasses the Curie temperature resistance value, temperature just no longer rises, can stably keep stationary temperature, that is to say, the heating physical efficiency of being made up of positive temperature coefficient thermis possesses self temperature controlled function.Thereby the heater that is equipped with such heater does not need to be used for the control circuit of constant heating temp and is used for anti-overheated circuit.And high fail safe arranged.

Real public clear 47-26226 communique discloses this heater.Its structure is: electrode is arranged on the upper and lower surface of the tabular heater of being made up of positive temperature coefficient thermis, and terminal block is arranged on the outside of this two electrode, and heating panel is arranged on a terminal block outside, and insulation board is arranged on another terminal block outside.And opening clear 58-53498 communique discloses another kind of heater in fact.Its structure is that electrode is arranged on the upper and lower surface of the tabular heater of being made up of positive temperature coefficient thermis, battery lead plate, and promptly terminal block is arranged on the outside of this two electrode, and insulation board is arranged on the outside of this two terminal block.In above-mentioned two heaters, be connected on the terminal block as for example available scolder of the lead-in wire of supply lines.Be connected with power supply by this lead-in wire, can power to heater.But in above-mentioned such structure, the insulation system imperfection exists fail safe to hang down such problem when particularly using in many wetlands side.

The method that solves such problem is disclosed in the real fair 3-9283 communique.Its structure is that electrode is arranged on by positive temperature coefficient thermis and constitutes on the upper and lower surface of tabular heater, wire bonds is in the outside of this two electrode, these heaters, the connecting portion that two electrodes and lead-in wire are connected with electrode uses the thermal conductivity insulating resin of being made up of silicone resin etc. by multiple.

Yet in above-mentioned structure, because wire bonds in the outside of two electrodes, is necessary to carry out by multiple with the thermally conductive resin of the such thickness of protuberance that can cover the electrode surface that produces because of welding lead, to obtain the good insulation performance state.Like this in above-mentioned structure above-mentioned resin bed thickening.As a result, in above-mentioned structure, it is big that the heater thickening becomes, and this can not be transmitted to the such problem of heating object efficiently with regard to having produced the heat that heater produced.

As mentioned above, in the heater of positive temperature coefficient thermis as heater, when the multiple and insulation system of the quilt of heater was improper, existence caused the problem of electrical characteristic deteriorations such as resistance variations and defective insulation during use.This deterioration is to be produced by the influence of the dust in the surrounding atmosphere, moisture etc.Particularly under the electrode surface generation dewfall situation of above-mentioned heater, because moisture is arranged, at electrode surface electrochemical reaction will take place when powering up, its resistance will change a lot.Therefore,, in public clear 53-47500 communique of spy and real fair 3-9283 communique, disclose, above-mentioned heater is carried out by multiple with the multiple member of the quilt of electric insulations such as resin material for solving such problem.

For example, in the disclosed method of above-mentioned special public clear 53-47500 communique, lead-in wire is connected to heater forms heat-generating units, with multiple this heat-generating units of the multiple material quilt of electrical insulating property quilt.At this moment, for suitably carrying out the location of the heat-generating units in the multiple member of electrical insulating property quilt that forms with finishing die easily, operate by following program.

At first, prepare a upper opening, on diapire, form the plastic barrel of each corresponding aperture that goes between with heat-generating units.Secondly, under the state that lead-in wire is drawn from above-mentioned aperture, heat-generating units is arranged on the inside of this plastic barrel.Then, make heater be in the center of tube, and make aperture airtight, lead-in wire is fixed on aperture portion with sealant.In tube, inject epoxy series plastics material subsequently and make it sclerosis.

In above-mentioned known method, carry out: the operation that goes between and draw from the aperture of tube, make heater be in the operation of the center and the location of tube with tweezers etc., and lead-in wire being fixed on operation of aperture portion etc. with sealant, these meticulous operations all are necessary.Like this, just produced the such problem of operation hell to pay that is recurred hot cell with the multiple member of electrical insulating property quilt again, real fair 3-9283 communique does not provide any method that addresses the above problem.Up to now, in high-temperature rooms such as bathroom, be to use by heating and prevent the anti-fog filter that minute surface hazes.

Embodiment 1

With reference to Fig. 1～Fig. 8 a most preferred embodiment of the present invention is described below.

As shown in Figure 1, in the anti-fog filter 17 of present embodiment, heat transfer plate 2 is for example by pasting the back side that is arranged on rectangle mirror 1 with binding agent.A plurality of heaters 3 as heating appliances are installed on the back side 2C of this heat transfer plate 2 with predetermined interval.These heaters 3 are equipped with Fig. 3 and heater 4 shown in Figure 4.

The good metallic plate of above-mentioned heat transfer plate 2 usefulness thermal conductivity, for example aluminium sheet is made into the rectangle littler than mirror 1.On this heat transfer plate 2, form in order to the installing hole 2a as shown in Figure 2 of above-mentioned heater 3 to be installed.Form 5 installing hole 2a in the central authorities of heat transfer plate 2 with from four jiaos of preset distances of mediad.

The installation of heater 3 on heat transfer plate 2 installed with counter-sunk screw 6 and nut 7 at above-mentioned installing hole 2a as shown in Figure 2.But installing hole 2a is processed into the shape that the head 6a of the counter-sunk screw 6 of fixed heater 3 is absorbed in.That is to say that each installing hole 2a becomes cylindric space apart from the predetermined distance range of the back side 2c side of heat transfer plate 2, the end in this space is big more to front 2b diameter more, becomes coniform.Therefore the front 2b of the heat transfer plate of pasting with the inside of mirror 12 becomes smooth.The shape and size of these installing holes 2a are corresponding with the geomery of counter-sunk screw 6, do not have restriction especially.

Above-mentioned heater 3 as shown in Figure 3 and Figure 4, by heater 4, metal terminal 88, constituted by the insulation crust 10 of multiple member as the lead-in wire 99 of supply lines with as electric insulation.

Above-mentioned heater 4 is by forming as the positive temperature coefficient thermis that the ceramic semiconductors of the barium titanate series of primary raw material constitutes with barium titanate, is doped with the oxide of the such rare earth element of a spot of lanthanum, yttrium that positive temperature coefficient arranged and the oxide of niobium, bismuth etc. in the barium titanate.This positive temperature coefficient thermis has from room temperature to Curie temperature Tc(resistance cataclysm temperature) be low resistance, surpass the characteristic that Curie temperature Tc resistance value sharply increases.Because this characteristic, in a single day heater 4 is coupled with voltage, and resistance value is little when initial low temperature, and the electric current that flows through is big, and power consumption is big, and temperature sharply rises.Subsequently, because temperature sharply increases above resistance value behind the Curie temperature Tc, power consumption reduces significantly.Thereby heater 4 can not rise to more than the uniform temperature, but stably remains on this uniform temperature.That is to say the temperature controlled function is arranged himself.This heater 4 can make its Curie temperature Tc set arbitrarily in about 30～270 ℃ scope by adjusting the composition of its material.For example, just can make Curie temperature Tc from 120 ℃ of common risings with the plumbous a part of barium that replaces in the barium titanate.If replace a part of barium, just can make Curie temperature Tc step-down with strontium.Thereby, set Curie temperature Tc as long as consider service condition, fail safe and the power saving of heater 3 to heater 4, just can make mirror 1 obtain effectively antifog surface temperature.

Above-mentioned heater 4 is oblate tubular as shown in Figure 5, by in the above with following coating silver coating for example, form electrode 4a, 4a.There is the location hole 4b that connects top and bottom in central authorities at heater 4.

Metal terminal 8 forms almost impartial tabular in the outer radius of heater 4 shown in Fig. 5 b and 5c, at the place, aperture of the location hole 4b of heater 4 centre almost equal location hole 8b is arranged.Be formed on metal terminal 8 in order to the power supply 8a that connects lead-in wire 9.This two power supply 8a, 8a are parallel to each other, and become the state stagger mutually in relative direction, go between accordingly 9,9 to extend to input direction.

The electrical connection of metal terminal 8 and heater 4 uses the conductive adhesive (as the DEMETRON6290-0343 of デ グ ザ) of for example epoxy/silver mixing to be glued together and to finish by the electrode 4a and the metal terminal 8 that are arranged on the heater 4.Each goes between and 9,9 is connected the opposite face side of power supply 8a, 8a by scolder etc.

At this moment, position relation by above-mentioned power supply 8a, 8a, article one, lead-in wire 9 is connected with a metal terminal 8 in primary importance, another lead-in wire 9 is connected with another metal terminal 8 in the second place, above-mentioned primary importance is positioned at the side of the plane vertical with electrode 4a as boundary, and said second position is positioned at the opposite side of above-mentioned plane as boundary.Therefore, lead-in wire 9,9 does not hinder heater 4 slimmings.Above-mentioned lead-in wire 9,9 as shown in Figure 4, and is parallel with the installed surface of heating object in the insulation crust 10 and all draw from shell 10 in the same manner with the distance of above-mentioned installed surface.Heat-generating units 14 shown in Fig. 5 c is by above-mentioned heater 4, metal terminal 8,8 and go between and 9,9 constitute.

The material of insulation crust 10 is as 6 nylon electric insulation thermoplastic plastics such as (6-チ ィ ロ Application), as shown in Figure 4, is to be made of by the insulation crust bottom 11 of complex radical body, insulation crust top 12 conduct.This insulation crust 10 is made by recurrence hot cell 14 and forms sealing, forms in the central heater 3 usefulness screw clamps are fixed to the fixing hole 3a that uses on the heating object.For avoid going between 9 and the welding portion of the power supply 8a of metal terminal 8 bear weight loading and rupture, insulation crust 10 also covers the metal terminal 8 side afterbodys of lead-in wire 9.

Above-mentioned insulation crust 10, for example, by heat-generating units 14 being assemblied in advance on the insulation crust bottom 11 that forms with injection moulding method, after again it being installed in the metal pattern that injection molding forming uses, plastics with the electrical insulating material that constitutes insulation crust top 12 carry out the injection model shaping, thereby an integral body is formed at insulation crust bottom 11 and insulation crust top 12.Therefore, heat-generating units 14 except that lead-in wire 9,9 open end all sealing and fixing in insulation crust 10.With the corresponding position of periphery of the fixing hole 3a of above-mentioned insulation crust bottom 11 be positioning convex portion 11a.Positioning convex portion 11a embeds the location hole of heater 4 and location hole 8b, the 8b of metal terminal 8,8 when being assembled to heat-generating units 14 on the insulation crust bottom 11, with heat-generating units 14 location.Thereby the position that becomes carrying heat-generating units 14 on every side of the positioning convex portion 11a on the insulation crust bottom 11.

The thermal endurance that insulation crust 10 must possess that thermal contraction is little, thermal conductivity and mechanical strength are good, can stand the heating temp of heater 4, moisture such as water and steam do not penetrate inner water proofing property, do not penetrate inner characteristic such as airtight with air, also want and 9,9 the multiple material of quilt of going between has good adhesiveness.So insulation crust uses the polymer alloy of being made up of for example nylon, polypropylene and glass fibre to form.Insulation crust 10 also available heat hardening plastics forms.

Insulation crust bottom 11 and insulation crust top 12 usefulness are made with a kind of electrical insulating material of or same nature, and from for making mutual compatibility good, the coefficient of expansion equates that the viewpoint of being convenient to integration is only.But from heat conducting viewpoint, want heat to be conducted well to heating object to well insulation crust bottom 11, and insulation crust top 12 heat release in air is the smaller the better.When paying the utmost attention to back one viewpoint, consider mutual compatibility and thermal coefficient of expansion, all good material of thermal conductivity and electrical insulating property, for example above-mentioned polymer alloy can be used in insulation crust bottom 11, the low material of thermal conductivity, for example epoxy resin can be used in insulation crust top 12.

As shown in Figure 1, the lead 9,9 that connects with each heater 3 is connected with power line 13, is connected with external power source by power line 13.

In said structure, at first the manufacture method to heater 3 describes.

At first make, sinter into the flat heater cylindraceous 4 shown in Fig. 5 a.Secondly this above heater 4 and below coating silver coating and sintering, form electrode 4a, 4a.

Then shown in Fig. 5 b, metal terminal 8,8 usefulness conductive adhesives are pasted on electrode 4a, the 4a of heater 4, a plurality of lead-in wires 9 are welded to the power supply 8a of metal terminal 8,8, the opposite side of 8a.Perhaps, also can after being welded to each lead-in wire 9 on power supply 8a, the 8a, with conductive adhesive metal terminal 8,8 be pasted on electrode 4a, the 4a again.This just can obtain heat-generating units such shown in Fig. 5 c 14.
