Description
Die Erfindung betrifft einen Heizer nach dem Oberbegriff des Patentanspruchs 1. Es kann ein Heizkörper, insbesondere für Küchengeräte, z.B. ein Strahlungsheizkörper oder anderer Heizkörper zur Beheizung einer Kochstelle, einer Backofenmuffel oder anderem sein. Derartige Heizkörper bilden meist eine in sich geschlossene Baueinheit, die als solche dann an dem entsprechenden Gerät, z.B. einer Herdmulde, einer Muffelwandung oder dgl. zu befestigen ist. Eine Heizseite des Heizkörpers bildet dann den entsprechend großflächigen Ausgang für die thermische Leistung des Heizkörpers. Widerstände, wie Heizwiderstände, Vorwiderstände oder ähnliche Bauteile, können in einer Ebene vorgesehen sein, die zur Ebene des thermischen Ausganges etwa parallel bzw. im Abstand zurückversetzt liegt.The invention relates to a heater according to the preamble of Claim 1. It can be a radiator, especially for Kitchen appliances, e.g. a radiant heater or other Radiator for heating a hotplate, an oven muffle or other. Such radiators usually form a self-contained unit, which then as such the corresponding device, e.g. a hob, a muffle wall or the like. is to be fastened. A heating side of the The radiator then forms the correspondingly large area Output for the thermal output of the radiator. Resistances, such as heating resistors, series resistors or the like Components can be provided in one plane, for Level of the thermal output approximately parallel or at a distance is set back.
Dem jeweiligen Widerstand ist zweckmäßig eine Isolierung zugeordnet, die gleichzeitig den einzigen Träger zur mechanischen Halterung eines oder aller Widerstände bilden kann und zweckmäßig eine durchgehende Flächenausdehnung hat, die etwa in der Größenordnung des thermischen Ausganges liegt, wofür sich insbesondere eine eben plattenförmige bzw. nur wenige Millimeter dicke Ausbildung der Isolierung eignet. Die Isolierung ist vorrangig elektrisch isolierend und kann auch thermisch isolierend sein, muß aber für sichtbare thermische Strahlung, z.B. Infrarotstrahlung wenigstens im Bereich des Eingriffes des jeweiligen Widerstandes, nicht undurchlässig sein. Wenigstens in diesen Bereichen kann die Isolierung auch so ausgebildet sein, daß vom eingreifenden Abschnitt des Widerstandes nicht nur in der ersten Phase der Inbetriebsetzung, sondern ebenfalls im Dauerbetrieb etwa soviel Wärme wie vom nichteingreifenden Abschnitt oder mindestens der größte Teil davon abgeleitet wird.Isolation is appropriate for the respective resistor assigned, which at the same time is the only carrier for mechanical Can form one or all resistors and expediently has a continuous surface area, which is about is in the order of magnitude of the thermal output for what in particular a flat plate-shaped or only a few Millimeter thick insulation is suitable. The insulation is primarily electrically insulating and can also be thermally insulating, but must be visible for thermal Radiation, e.g. Infrared radiation at least in the range of Intervention of the respective resistance, not impermeable his. At least in these areas, the insulation can too be designed so that from the engaging portion of the Resistance not only in the first phase of commissioning, but also in continuous operation about as much heat as from the non-engaging section or at least the largest Part of it is derived.
An einer Isolierung, die z.B. aus einer breiig in Form gegossenen Schüttung mit mineralischen Fasern, Körnungen, Bindemittel oder dgl. in Form gebracht bzw. gepreßt und dann getrocknet bzw. ausgehärtet wird, sind Widerstände gegen Abheben verhältnismäßig schwer zu sichern, während die Sicherung gegen seitliche Bewegungen durch Eingriff in Vertiefungen bzw. zwischen Vorsprünge der Isolierung weniger schwierig ist. Zur Abheb-Sicherung können Befestigungsglieder dienen, die in Form von Krampen, Klebepunkten oder ähnlichen gesonderten Bauteilen bzw. in Form von abgewinkelten Vorsprüngen einteilig mit dem Widerstand ausgebildet sein können und sowohl mit dem Widerstand verbunden sind als auch in die Isolierung eingreifen.An insulation, e.g. from a mushy cast Fill with mineral fibers, grain sizes, Binder or the like. Formed or pressed and then is dried or cured, are resistances against Taking off is relatively difficult to secure while securing against lateral movements by engaging in recesses or less difficult between protrusions of the insulation is. Fastening elements can be used to secure against lifting off. those in the form of staples, glue dots or similar separate Components or in the form of angled projections can be formed in one piece with the resistor and are connected both to the resistor and into the Intervene insulation.
Insbesondere im Falle von Flachwiderständen bilden derartige Befestigungsglieder dann aber widerstandsinaktive Bauteile insofern, als sie zum elektrischen Widerstandswert nicht beitragen, nämlich eher nach Art von Blindabzweigungen vom Strom nicht oder gegenüber den Abschnitten mit maximaler Durchflußdichte nur wesentlich reduziert durchflossen sind. Diese Befestigungsglieder erhöhen im Fall bestimmter Ausbildungen die Kompliziertheit sowie ggf. nicht vernachlässigbar das Gewicht des Heizkörpers und werden im wesentlichen nur durch Wärmeleitung bzw. Strahlung von den widerstandsaktiven Bereichen des Heizwiderstandes erwärmt, nicht jedoch durch eigene Widerstandsarbeit. Runddraht-Widerstandwendeln können demgegenüber mit widerstandsaktiven Befestigungsabschnitten unmittelbar in die Isolierung dicht umschlossen eingebettet sein. Dies gilt auch für Flachwiderstände, die z.B. als nicht eigenstabile aufgedampfte Schicht wenigstens teilweise liegend oder vollständig zwischen Isolierschichten eingebettet an der Isolierung befestigt sind. Gegenüber solchen Widerständen haben Flachwiderstände, deren widerstandsaktive Querschnitte wenigstens teilweise nicht parallel zur Heizseite bzw. Heizebene, sondern demgegenüber geneigt bis rechtwinklig liegen, wesentliche Vorteile, weil sie auch bei hoher Widerstandleistung quer zu ihrer Längsrichtung und etwa parallel zur Heizebene weniger Raum beanspruchen und daher in höherer Leistungsdichte angeordnet und gegen Kriechströme besser isoliert werden können. Ihre Sicherung gegen Abheben ist dagegen aus den oben genannten Gründen schwieriger und aufwendiger.In the case of flat resistors in particular, they form Fasteners then resistance-inactive components insofar as they don't relate to the electrical resistance value Contribute, namely rather in the manner of blind branches from No electricity or compared to the sections with maximum Flow density are only significantly reduced. These fasteners increase in the case of certain training the complexity and possibly not negligible the weight of the radiator and are essentially only through heat conduction or radiation from the resistant ones Areas of the heating resistor are heated, but not by own resistance work. Round wire resistance coils can on the other hand with resistant fastening sections embedded directly in the insulation tightly enclosed his. This also applies to flat resistors, e.g. as not self-stable vapor-deposited layer at least partially lying or completely embedded between insulating layers are attached to the insulation. Towards such Resistors have flat resistors, their resistive ones Cross sections at least partially not parallel to the heating side or heating level, but inclined to right-angled are significant advantages because they are also high Resistance power transverse to their longitudinal direction and about take up less space parallel to the heating level and therefore in arranged higher power density and against leakage currents can be better isolated. Your security against taking off is, however, more difficult for the reasons mentioned above and more complex.
Die DE-A-2 551 137 zeigt einen Stützschenkel, der bis nach dem Einsetzen in den Grundkörper durchgehend eben ist und dann erst um eine zur Heizebene parallele Zone abgewinkelt wird.DE-A-2 551 137 shows a support leg which extends up to the insertion into the base body is completely flat and only then angled around a zone parallel to the heating level becomes.
Die US-A-600 057 zeigt für einen Flachwiderstand einen Stützschenkel, welcher im elastischen Bereich hin- und hergehend gekrümmt ist, so daß er bei Entspannung wieder in seine ebene, gestreckte Form zurückkehren würde.US-A-600 057 shows one for a flat resistor Support leg, which in the elastic range back and forth is curved here, so that he relaxes again when relaxing would return to its flat, elongated shape.
Der Erfindung liegt des weiteren die Aufgabe zugrunde, einen Heizkörper zu schaffen, mit welchem Nachteile bekannter Ausbildungen bzw. Nachteile der beschriebenen Art vermieden werden können. Bevorzugt soll ein Widerstand mit Flachquerschnitten im Bereich oder außerhalb dieser Querschnitte auf einfache Weise an der Isolierung lagegesichert, insbesondere gegen Abheben auch dann gesichert werden können, wenn wenigstens Teile des jeweiligen Flachquerschnittes quer zur Heizebene liegen. Ferner sollen ggf. thermische Überlastungen der Isolierung vermieden und/oder möglichst viele leitende bzw. Metallglieder, die elektrisch leitend mit dem Widerstand verbunden sind, in die elektrische Widerstandsarbeit einbezogen sein.The invention is further based on the object To create radiators with which disadvantages are known Formations and disadvantages of the type described avoided can be. A resistor with flat cross sections should preferably be used in the area or outside of these cross sections easily secured to the insulation, especially can also be secured against lifting if at least Parts of the respective flat cross section transverse to Heating level. In addition, thermal overloads may also occur the insulation avoided and / or as many conductive as possible or metal links that are electrically conductive with the resistor are involved in the electrical resistance work his.
Erfindungsgemäß sind die Merkmale nach Patentanspruch 1 vorgesehen.According to the invention, the features according to claim 1 intended.
Es werden Mittel vorgeschlagen, durch die der jeweilige Widerstand durch unmittelbare Eingriffsverbindung eines widerstandsaktiven Bereiches mit der Isolierung gegen Abheben gesichert ist. Zweckmäßig weist der Widerstand im Bereich dieses Befestigungsabschnittes und/oder anschließend an bzw. im Längsabstand von diesem Befestigungsabschnitt mindestens einen langgestreckten Längsabschnitt mit vollen Flachquerschnitten auf, die wenigstens teilweise quer zur Heizebene liegen.Means are proposed through which the respective resistance through direct engagement connection a resistant area with insulation against Taking off is secured. The resistance in the Area of this fastening section and / or subsequently on or in the longitudinal distance from this fastening section at least one elongated longitudinal section with full Flat cross sections that are at least partially transverse to Heating level.
Weist der Widerstand bzw. der Befestigungsabschnitt an seiner dem Kern der Isolierung zugekehrten Kantenfläche bzw. an der anderen Kantenfläche keinerlei abgesetzt vorspringendes und gegenüber den widerstandsaktiven Querschnitten vertieft in die Isolierung eingreifendes Befestigungsglied nach Art einer Blindabzweigung auf, so kann der jeweilige Befestigungsabschnitt bzw. der Widerstand über seine gesamte einteilige Längserstreckung ausschließlich widerstandsaktive Querschnitte aufweisen. Ferner kann dadurch die Bauhöhe der Isolierung, des Widerstandes und des gesamten Heizkörpers insbesondere dann reduziert werden, wenn die genannte Längskantenfläche im wesentlichen aller Längsabschnitte des Widerstands im wesentlichen in einer einzigen Ebene liegt. Oder wenn keine mit Abstand nebeneinanderliegenden und über einen Krümmungsbogen aneinanderschließenden Längsabschnitte des Widerstands vorgesehen sind, die unterschiedlich tief in die Isolierung eingreifen oder deren Längsrichtung im Winkel zueinander liegen. Die mittlere Längsachse aller Befestigungsabschnitte bzw. aller Längsabschnitte kann in einer einzigen Ebene vorgesehen sein, durch die die Heizebene definierbar ist. Has the resistor or the fastening section on it edge of the insulation facing the core or on the other edge surface no protruding and compared to the active cross sections the insulation engaging fastener like a Blind branch on, so the respective mounting section or the resistance across its entire one-piece Longitudinal extension only cross sections that are resistant to resistance exhibit. Furthermore, the overall height of the insulation, the resistance and the entire radiator in particular then be reduced if the mentioned longitudinal edge surface in essentially all of the longitudinal sections of the resistor lies in a single plane. Or if none with Distance next to each other and over a curve contiguous longitudinal sections of the resistor are provided, which have different depths in the insulation intervene or their longitudinal direction at an angle to each other lie. The central longitudinal axis of all fastening sections or all longitudinal sections can be in a single plane be provided, through which the heating level can be defined.
Der Heizwiderstand ist zur Sicherung gegen seitliche Bewegungen parallel zur Heizebene ebenfalls unmittelbar flächig an der Isolierung abgestützt, wobei seine beiden Seitenflächen im wesentlichen unter allen Betriebsbedingungen etwa auf gleicher oder unterschiedlicher Höhe eng an etwa parallelen Stützflächen der Isolierung anliegen können. Im Gegensatz zu einer Abstützung nur im Bereich einer scharfen Kante einer Kantenfläche und nicht auch im Abstand von dieser Kantenfläche wird dadurch eine sehr gute seitliche Abstützung erzielt. Der Widerstand kann außerdem auch gegen Bewegungen zum Kern der Isolierung gut gesichert werden, wenn er über mindestens die Hälfte seiner Länge oder seine gesamte Länge mit der zugehörigen Kantenfläche zumindest in einem Betriebszustand an der Isolierung abgestützt ist. Ist der jeweilige Befestigungsabschnitt rückfedernd z. B. dadurch vorgespannt, daß er etwa parallel zur Heizebene gekrümmt in die Isolierung eingreift, so erfolgt durch die aufweitend und/oder verengend wirkende Federkraft eine zusätzlich sichernde Verklemmung gegenüber der Isolierung.The heating resistor is to protect against lateral Movements parallel to the heating level are also immediate supported extensively on the insulation, being both Side surfaces essentially under all operating conditions about at the same or different height close to about parallel support surfaces of the insulation. in the Contrary to a support only in the area of a sharp one Edge of an edge surface and not also at a distance from it Edge surface is a very good lateral support achieved. The resistance can also be against movements be well secured to the core of the insulation when it is over at least half of its length or its entire length with the associated edge surface at least in one operating state is supported on the insulation. Is the respective one Resilient section resilient z. B. biased thereby that it is curved approximately parallel to the heating level in the insulation intervenes, so takes place through the expanding and / or narrowing acting spring force an additional securing jamming versus insulation.
Der jeweilige Befestigungsabschnitt
bzw. der gesamte Widerstand ist durch einen Flachdraht
bzw. ein Flachband gebildet, dessen jeweilige Längskante
im gestreckten, also längsten Zustand, durchgehend annähernd
geradlinig ist und/oder dessen seitliche Flächen von
eventuellen Vorsprüngen oder Durchbrüchen auch frei sein
können. Die Materialdicke des Flachquerschnittes kann dabei
weit unter einem halben Millimeter liegen und je nach den
Erfordernissen jedes ganzzahlige Vielfache eines zehntel
Millimeters oder eines hundertstel Millimeters, z.B. sieben
hundertstel Millimeter, betragen. Die Materialbreite bzw.
Höhe des Flachquerschnittes beträgt zweckmäßig mehrere Millimeter,
insbesondere weniger als 5 mm, und kann je

quer vom Boden 7 im wesentlichen spielfrei gesichert
sind. Die Widerstände 10, die hier als Heizwiderstände wenigstens
teilweise frei innerhalb des Napfraumes liegend vorgesehen
sind, können in ineinanderliegenden ein- oder mehrfachen
Spiralwindungen bzw. Spiralen etwa parallel zum Rand 8
angeordnet sein. Die Widerstände 10 sind bevorzugt im wesentlichen
gleichmäßig über ein Feld verteilt, das über den
gesamten Umfang annähernd an den Innenumfang des Randes 8
anschließt und bis ins Zentrum des Bodens 7 reicht.The respective mounting section

or a flat band formed, the respective longitudinal edge

well below half a millimeter and depending on the
Requirements any integer multiple of a tenth

hundredths of a millimeter. The material width or

Jeder Widerstand 10 weist über seine gesamte Länge durchgehend
genau gleiche, annähernd rechteckige Flachquerschnitte
dadurch auf, daß er aus einem Flachband hergestellt ist, das
nicht schneidend bzw. unter Entfernung von Materialanteilen
weiterverarbeitet wird, um den Heizwiderstand herzustellen.Each
Vielmehr wird das Flachband nur biegend verformt. Es weist
zwei im Querschnitt parallele Seitenflächen 12, 13 und zwei
diese verbindende, sehr schmale Kantenflächen 14, 15 auf,
wobei seine Dicke 29 z. B. etwa 0,07 mm und seine größte
Querschnittsweite bzw. Breite 28 z. B. etwa 3 mm betragen
kann. Das jeweilige Bandende des Widerstandes 10 kann unmittelbar
und ohne zusätzliche Zwischenglieder als elektrisches
Anschlußende 16 ausgebildet sowie durch Biegen bzw. Verschränken
gegenüber dem übrigen Widerstand 10 in eine Lage
gebracht sein, in welcher es gegenüber der Isolierung 3
berührungfrei ist und sich für den elektrischen Anschluß
besonders gut eignet.Rather, the flat strip is only deformed in a bending manner. It points
two
Ein einteilig durchgehendes Flachband kann auch zwei zueinander benachbarte, gesondert schaltbare Widerstände bilden, wenn diese an ihren Enden über einen Querabschnitt einteilig ineinander übergehen und/oder der diese Einzelwiderstände verbindende Querabschnitt einteilig mit einem entsprechenden Anschlußende ausgebildet ist.A one-piece continuous ribbon can also be two to each other form adjacent, separately switchable resistors, if these are in one piece at their ends via a transverse section merge into one another and / or these individual resistors connecting cross section in one piece with a corresponding Connection end is formed.
Der jeweilige Widerstand 10 bildet einen über den größten
Teil seiner Länge bzw. seine gesamte Länge ununterbrochen
durchgehenden Befestigungsabschnitt 17 dadurch, daß er über
diese Länge ununterbrochen unmittelbar so in Eingriff mit dem
Tragkörper 4 steht, daß er gegenüber diesem gegen Bewegungen
in den genannten Richtungen gesichert ist. Hierzu ist ein an
eine Kantenfläche 14 streifenförmig anschließender Eingriffsabschnitt
18 in eine entsprechend nutförmige Vertiefung 19
des Tragkörpers 4 ununterbrochen eingebettet. Der Flachquerschnitt
11 bildet zwischen beiden Kantenflächen 14, 15 ununterbrochen
durchgehend widerstandsaktive Querschnitte, weshalb
auch der Eingriffsabschnitt 18 in gleichen Maße widerstandsaktiv
ist, wie die frei über den Boden 7 vorstehenden
Abschnitte des Flachquerschnittes 11.The
Die Eingriffstiefe des Eingriffsabschnittes 18 kann z.B. etwa
2 mm bzw. zwei Drittel der Gesamtbreite des Flachbandes
betragen. Die beiden Seitenflächen 12, 13 können im Bereich
des jeweils gemeinsamen Längsabschnittes auf unterschiedlicher
Höhe an dem Isolierwerkstoff des Tragkörpers 4 oder auf
gleicher Höhe anliegen, je nachdem, welche Abstrahlungsverhältnisse
bzw. Kopplelungswirkungen erzielt werden sollen. Je
nachdem, ob der jeweilige Spiralabschnitt in einem Bereich
durch Aufweitung oder Verengung elastisch vorgespannt ist,
liegt er unter Federspannung mit der inneren oder äußeren
Seitenfläche 13 bzw. 12 an.The depth of engagement of the engaging portion 18 may e.g. approximately
2 mm or two thirds of the total width of the ribbon
be. The two
Die Widerstände 10 liegen an der der Napföffnung zugekehrten
Heizseite 20 des Bodens 7 bzw. des Grundkörpers 2 und bestimmen
z.B. mit ihren näher beim thermischen Ausgang liegenden
Kantenflächen 15 eine zum Boden 7 etwa parallele Heizebene
21. Der Heizkörper 1 weist eine mittlere, zu dieser Heizebene
21 rechtwinklige Achse 22 auf, um welche die Widerstände 10
gekrümmt sind. Jeder Widerstand 10 hat zusätzlich zu seiner
elastischen Großkrümmung einen in seiner Längsrichtung wechselnden,
z.B. sinuswellenförmig gekrümmten Verlauf dadurch,
daß er in Ansicht auf die Heizebene 21 abwechselnd mit entgegengesetzten,
jedoch im wesentlichen gleichen Krümmungen 23
versehen ist und benachbarte Krümmungen mit ihren annähernd
geradlinigen bzw. ebenen Schenkeln 24 einteilig ineinander
übergehen.The
Entsprechend sind auch der Eingriffsabschnitt 18 und die
nutförmige Vertiefung 19 bleibend bzw. eigensteif gekrümmt,
wobei die Schenkel 24 von der jeweiligen Krümmung 23 divergieren,
zweckmäßig unter einem Winkel von mehr als 30°, 60°
oder 90°. Dadurch werden thermische Längendehnungen des
Widerstandes verhältnismäßig unproblematisch, nämlich hauptsächlich
in Längsrichtung der Vertiefung 19 auf den Tragkörper
4 übertragen. Der Befestigungsabschnitt kann auch durch
Streckung und/oder Stauchung der Wellung bzw. des Widerstandes
10 in einzelnen Teil- oder allen Längsabschnitten in
Längsrichtung vorgespannt sein, so daß er rückfedernd mit
Spannung an entsprechenden Querflanken einer oder beider
Seitenflächen der Vertiefung 19 anliegt. Auch können die
beiden Schenkel 24 jeweils eines Wellenbogens eine entsprechend
verengt oder aufgeweitet vorgespannte Klammer bilden,
die mit der Vorspannung an der zugehörigen Seitenfläche der
Vertiefung 19 anliegt. Wenigstens im Bereich dieser Seitenflächen
ist der Tragkörper 4 unter diesen Spannkräften rückfedernd
druckelastisch nachgiebig, so daß sich eine sehr
sicher haltende Verkrallung des Widerstandes 10 ergibt. Die
Druckfestigkeit des Materials des Widerstandes 10 ist demgegenüber
wesentlich höher. The engagement section 18 and FIG

Der Innenumfang 27 des Randes 8, der gemäß Fig. 3 auch einen
vom Tragkörper 4 gesonderten Bauteil bilden kann, begrenzt
praktisch den thermischen Ausgang des Heizkörpers 1 am Außenumfang.
Gemäß Fig. 3 steht die freie Stirnfläche 25 des
Randes 8 um ein geringes Maß über die Stirnfläche des Randes
9 vor, so daß eine strahlungsdurchlässige Deckplatte 26 aus
Glaskeramik oder dgl. mit ihrer ebenen Rück- bzw. Unterseite
unter Druck vorgespannt an dieser Stirnfläche 25 anliegen
kann. Das Vorstehmaß, das z.B. etwa der Blechdicke der
Fassung 6 entsprechen kann, ist so groß, daß zwischen der
Rückseite der Deckplatte 26 und dem Rand 9 nur ein Spaltabstand
ist. Weicht die Stirnfläche 25 unter dem Druck bzw.
durch Alterung des Randes 8 zur Heizebene 21 aus, so kann
dadurch der Rand 9 nicht in unmittelbare Berührung mit der
Deckplatte 26 gelangen, sondern der Spaltabstand kann sich
höchstens auf ein Minimum von z.B. 1 mm oder dgl. verringern.The
Die Heizebene 21 liegt im Abstand gegenüber der Stirnfläche
25 bzw. der Deckplatte 26 zurückversetzt. Allerdings kann der
jeweilige Heizwiderstand bzw. können gesonderte Heizwiderstände
unterschiedlich weit über den Boden 7 zur Heizseite 20
frei vorstehen, unterschiedlich tief in den Tragkörper 4
eingreifen, unterschiedliche Bandbreite und/oder unterschiedliche
Banddicke haben, wodurch Bereiche des Heizfeldes mit
unterschiedlicher Leistungsdichte bzw. unterschiedlicher

Der gewellte Widerstand kann ohne vorherige Herstellung der
Vertiefung 19 in den trocken vorgefertigten
Tragkörper 4 eingedrückt werden. Beim Eindrücken in
den Tragkörper 4 weicht das Isoliermaterial verdichtend aus,
wonach es gegen den Eingriffsabschnitt 18 zurückfedert oder
zurückfließt, so daß der Widerstand 10 dann gegen Abheben
vom Boden 7 sehr gut formschlüssig gesichert ist. Der Widerstand
10 kann dabei bis zum Anschlag seiner Kantenfläche 14
