Description
The present invention relates to a kind of tabular sandwich type element that is provided with zone of heating, this element has the feature of claim 1 preamble.
On other on glass or non-conductive carriers, carry out such heating and can be used as calandria (by radiation), if the heating power of being installed satisfies described purpose.These heating elements can be installed on the wall of building or wherein or join in this building, promptly replace common (central authorities) calandria.For this reason, must not be embodied as the form of window, can also be the mirror form, the combination with decorative surfaces form, or the like.Generally speaking can also use tabular element so that the surface by plant equipment, for example the surface of household electrical appliance produces heat, and the less setting height(from bottom) of described equipment and the smooth surface that is highly susceptible to cleaning can provide very big advantage.
The power supply supply of the zone of heating on big surface requires to use high relatively voltage.Therefore reliable electric insulation must be set, particularly may be on the edge of the plate that is capped on the whole surface at involved.
Documents DE-A119860870 has described the fuel plate of the above-mentioned type, and wherein glass carrier is capped on its whole surface.In order to isolate the cover layer to externally fed reliably, the zone that constitutes this cover layer peripheral frame is isolated and therefore is electric neutrality by shielding wire.Such setting has also protected this cover layer not to be corroded, and described corrosion enters this cover layer from described external margin, but this corrosion cover layer only penetrates into this defiber place.
The electrical connection of this zone of heating contacts with the cover layer that is positioned at this interior surface, and described surface is limited by this framework, and other shielding wire defines the path that hot-fluid flows through on this tectal whole surface.Same documents has also disclosed following selection: for a plurality of bonding glass pane of a described multiple-glazing unit or safety glass window provides conductive covering layer.Yet specifically describe to implement such multiple glazing, also do not relate to and electrically contacting, also be not used in such two of electric control and add thermal blanket.
In another known fuel plate (documents DE-B-2113876), this conduction and add the edge that thermal blanket does not extend to this plate is so that the spacing frame of an insulating glass window need not directly be bonded on the edge (not having layer) of this windowpane with designing especially.The current supply line of this electrode is by being arranged on the closed hole in this spacing frame.Second glass pane of this insulating glass window is provided with the not zone of heating of sunlight protection.
A kind of jockey that is used for tabular sandwich type element has been described in the applicant's previous patent application 10241728.8, comprises the first rigidity glass pane that is provided with a zone of heating and at the second rigidity glass pane of whole surface and this first glass pane bonding connection.This jockey is inserted in the hole in one that is arranged in the described rigidity glass pane.This device comprises the contact portion that allows foundation and this zone of heating directly to contact.For this reason, described zone of heating has at least two electrodes, and described electrode is arranged in the zone of described cutting part.Be extended with a plurality of circuit paths that are electrically connected in parallel between described electrode, this path is arranged in the described cover layer.
The surface conductivity of the length of this current path and width and employed layer system (ohm with unit are is represented) has determined the absorption of electric energy and the heating power of this fuel plate.According to available or predetermined special supply voltage, can interiorly on a large scale set up different heating powers by the pattern of current path, the maximum temperature of permission also depends on the use field of the fuel plate of completion.If for example the user can not contact or need not suppose that the user can contact it, then described temperature can be fully on 50 degrees centigrade.Yet, clearly must avoid being bonded in the cover layer on this glass pane that is capped, the temperature that reaches when for example the adhesive plate of multiple-glazing unit is along with operate as normal and going bad.
In documents, mentioned different materials, they are suitable for such zone of heating.As just example ground, here provide indium and tin-oxide (indium tin oxide-ITO) and the metal of good conduction, as gold, silver, copper and aluminium.The described layer system that is provided with antireflecting dielectric layer and at least one metal level between described dielectric layer has allowed by gratifying electrical conductivity that visible light is extraordinary to be passed through, but simultaneously can also be with the ultrared reflection unit of opposing.The sheet resistance that layer system commonly used like this has is unit are 1-4 ohm.
When these heating elements were worked under high heating power, this adhesive layer generally was that thermoplastic layers (preferably PVB, PMMA or EVA sheet) can reach thermoae limit value.The surperficial bonding of this glass can be unclamped after whole heating power has applied the considerable time interval.High-density current is set in some cases and particularly, and above-mentioned situation can cause this tectal local delamination.For the reason of technology and production and cost, do not wish to give up and produce the adhesive that stands to test for many years behind the glass pane, therefore seeking other modes avoids described heat problem.
Problem to be solved by this invention is: provide a kind of better element that is provided with the tabular multilayer of zone of heating.
According to the present invention, this problem is solved by the characteristic of claim 1.The characteristic of dependent claims has provided the preferred improvement to this purpose.
At first, by two cover layers, provide following selection: equally with single cover layer obtain same heating power, significantly do not increase the volume of calandria simultaneously, described layer thickness is positioned at nanometer range, and the electric current of unit are is very little for each cover layer.Therefore this heat is not only produced by a positive layer between this glass plate and adhesive phase.In addition, the thermal force of described connection electrode is reduced, and must extend in all current paths by this total current of described connection electrode.Other of this structure of the present invention are characterised in that described two cover layers electrically contact the flat sides of this fuel plate, because in described two plates is provided with cutting part, this cutting part allows described outside the connection to pass through.
In first preferred implementation of the present invention, described two cover layers are arranged on two sides of this adhesive layer, and described adhesive layer connects described two rigidity glass panes.In second preferred implementation, thickness according to this rigidity glass pane provides this tabular sandwich type element big slightly gross thickness, in this embodiment, one the 3rd rigidity glass pane is set, and at least one zone of heating is set in the both sides of the 3rd rigidity glass pane.Especially, be not necessary to ask this central authorities' glass pane to carry described two zones of heating, can realize the setting of various deformation, and will make an explanation in detail in the back.
If expect the distribution that this heating power is concentrated, can also implement other combinations of described two distortion, under the situation of needs and can also add other rigidity glass pane (be capped or be uncovered) within the scope of the present invention.
In all structures,, then can obtain control to the distribution of this heating if described two cover layers are identical and by identical supply voltage energize (voltage of the common electrical network of the most handy involved country (for example 110 or 230V)).
In a favourable improvement, the cover layer of described each heating resistor of formation (parallel) can be implemented independently of one another respectively or be used in the series circuit or in the parallel circuits.
Under the situation of back, can obtain the highest heating power; Described heating power can be set for example to be used to heat still cold heating element and to use less heating power so that work for a long time.
Also allow to equip described two cover layers of the performance of different complementations according to structure of the present invention.On the one hand, described cover layer can be implemented with different materials.Their resistance can be regulated in big scope, for example by selecting the specific conductivity and/or the internal structure of this layer system so that even when on this layer system, apply identical supply voltage the different heating power of acquisition.
In addition, described cover layer can also be embodied as different thickness.Therefore, comprise identical materials or different materials, on sheet resistance, work according to the cover layer of described different-thickness.
In addition, particularly in transparent tabular heating element situation, the selection of this material also allows the color characteristic that obtains to expect.For example Jin cover layer has that more increase the weight of or more shallow golden yellow or red tone, and silver layer has neutral more tone.
Clearly, can also on fuel plate of the present invention, design a plurality of current paths in a manner known way, this current path can be connected to one inside in described two cover layers independently of one another, so that can connect or disconnect this heating power step by step when needed.This depends on the number of on described cover layer obtainable contact portion or connection electrode.
When production does not have the tabular heating element of window function, can remove the anti-reflex treated of proper conductive layer, this conductive layer is for example implemented with silver or other conducting metals, thereby simplify electric current supply (the antireflecting layer of described dielectric is not conduction or poor conductive traditionally) on the one hand, obtained surface decoration effect on the other hand.The accurate of suitable material for this zone of heating system determined by those skilled in the art's decision of carrying out the heating power calibration operation of expectation.
As a supplement, the temperature sensor that one or more is used for the effective temperature of check-out console linear element can be set.Such temperature sensor setting is embodied as the form (for example its resistance/Ohmic resistance is along with the conductor of temperature increase) of demand limiter.Can design a kind of different switching device that is used for disconnecting heating current under the situation of too high this fuel plate of heating in addition, described device can hard to bear temperature sensor control.
In particularly advantageous mode, fuel plate of the present invention can be equipped the jockey in the described type of first to file above-mentioned.A jockey in the cutting part in one in can making described two zones of heating simultaneously and will being arranged on this glass pane contacts.Therefore can be advantageously and very compactly the electrical connection of described heating element is compiled.This Connection Element can comprise necessary conversion element for the heating power of this heating element of control simultaneously.Particularly be independent of described one or two tectal control elements, may be a plurality of independently current paths that are positioned at described one or two cover layer inside, described element allows to set up polyphone or connection in parallel, and the conversion element that may be controlled by heat sensor.At last, for safety disconnects, can also be arranged on necessary described conversion element under the possible crack conditions of heating element of glass,
This jockey advantageously is mounted and can be removed when needed after producing this tabular sandwich type element.Particularly advantageously, this jockey has been equipped contact device freely, for example plug-type or spring contact portion, and for the higher service voltage of tabular sandwich type element, described contact portion must only be transmitted little electric current (interchange); In addition, employed heating element generally is not given a shock in building.Therefore needn't expect etching problem, at other applications (automobile construction), described etching problem can cause stoping described contact because transmitting the increase of resistance.In addition, this join domain or contact area when needed can be sealed, so that there is not moisture also not have dirt to enter.
When needed, towards described function element electrically contact part or according to circumstances their electrode can implement the protection that perhaps only has complementary character by welding.Known the solder technology (responding to or laser welding) that allows the welding position directly not melted reliably contiguously with heating source, perhaps this solder technology even can be used by the glass pane that is capped, and can not destroy this cover layer.
The fuel plate that is equipped with according to the present invention can be used as automatic calandria.Can also join in the insulating glass, this fuel plate is connected by spacing frame with another glass pane in this insulating glass.Clearly other (glass) plates in the multi-layer sheet that connects on whole surface can also be connected on two rigidity glass panes of this tabular heating element, and not leave basic thought of the present invention here.
Other details of the present invention and advantage can from the accompanying drawing of embodiment and distortion and below the description carried out draw,
In the accompanying drawing of that show in letter and not to scale (NTS), accompanying drawing comprises:

For example can use a kind of cover layer, this cover layer is bought under " Planitherm1.3 " by the applicant, and this model is represented its k value.It comprises have high-heat strength layer system, this layer system can be by prestressing forceization, is provided with a silver layer and at the antireflecting dielectric layer of the both sides of this silver layer, this layer system also has the performance of reflected infrared ray.
Yet, as required, clearly can also use other conductive layer system.Its sheet resistance is 1-25 ohm per unit area.This sheet resistance is more little, and this flat heating element is big more, and this flat heating element must be heated under predetermined voltage.
Some suitable devices have been guaranteed the periphery passivation that the cover layer of this fuel plate 1 does not illustrate along its edge in a manner known way here, promptly do not exist to contact not exist to contact with the conduction of front face surface with the conduction of outer surface yet, do not exist yet because corrosion to the external damage of the material of described layer.Under any circumstance, by means of the synthetic thermoplastic jointing material that constitutes adhesive layer 3, obtained the sealing cover layer in slit, edge.The material that is appreciated that described adhesive layer must be chosen as the material compatibility with this cover layer 5.

The electrode 6 of two layers 5 can also be implemented as required in the same manner or differently.Be not in described two cover layers 5, identical electric current to be arranged and/or expect to have identical heating power in them in all performances.
Described proper electrode 6 is opaque and can not sees from the outside.Therefore, described electrode 6 can also be configured to decoration element, for example expresses a company or manufacturer's sign.
With shown in pantostrat different, described electrode 6 can also be deposited on described cover layer 5 below, promptly before this cover layer 5 is deposited on this glass surface, be deposited.Form that can sheet metal is implemented described electrode 5 or can also be embodied as the band of the conductive paste that can be roasted of silk screen printing (carry out prestressing forceization to this glass pane this moment).The embodiment that is also referred to as the suitable electrodes of busbar is extensively described in the prior art.By being used to implement the silk screen conductive paste colorize of this electrode, the color effect that can also obtain to limit.
Clearly described when needed electric contact area can be covered by some suitable device visions, for example an opaque decoration is arranged on the following of this contact area or in this zone, prints such decoration, go back or be used for the very cream of heavy tone of this glass pane.As example, this glass pane 4 carries an opaque cover layer 8 in this electrode zone, and this cover layer 8 is non-conductive and be printed on this glass surface before this covering 5 of deposition, roasts when carrying out prestressing force.
In the join domain of this electrode 6, with a hole or cutting part 9 is arranged in this glass pane 4 or in this adhesive phase 3.Described hole or cutting part 9 are used to make the external electric of two pairs of electrodes 6 of two cover layers 5 to connect by described hole or cutting part, with described two glass panes 2 with in this adhesive phase 3, process cutting part before 4 are connected, make this adhesive material not enter into this electrode 6 because of thawing.When needed suitable protection will be set.
In the hole 9 of this glass pane 4, fixed the insert 10 of a form of sleeve.Roughly corresponding to the thickness (about several millimeters) of this rigidity glass pane 4, this insert extend on the plane of this adhesive phase 3 axial length of this insert.A radial projection 11 of giving prominence to towards the outside is the edge in this hole 9 of hook from behind, makes this insert 10 be fixed to prevent to take out this insert 10 by the geometry of correspondence here.
With described two rigidity glass panes 2 with before 4 are connected, this insert must be arranged in this hole 9.Only this insert is fixed with just being defined when melting this thermoplastic cements's layer.Can see that in the accompanying drawings this projection 11 is also kept by described adhesive material 3.
