Die Elektronik-Bauelemente können dann direkt über die Anschlussbolzen oder der Verbindungseinrichtung in Kontakt mit der Heizeinrichtung stehen, um folglich das Erwärmen des Wassers im Heizblock zu steuern.It is preferred that the control device comprises power electronics components. The electronic components may then be in direct contact with the heater via the terminal bolts or the connection means, thus controlling the heating of the water in the heating block.
Vorteilhafterweise weist die Platine der Steuereinrichtung Bohrungen auf, welche derart angeordnet sind, dass die Bohrungen die Anschlussbolzen der Heizeinrichtung im eingebauten Zustand empfangen. Durch diese bevorzugte Ausgestaltung ist gesichert, dass die Montage immer fehlerfrei erfolgen kann. Falls beispielsweise die Steuereinrichtung um 180 Grad verdreht montiert werden sollte, würden die Anschlussbolzen und die Bohnrungen nicht übereinander passen. Infolgedessen wird durch die mechanische Montage bereits die korrekte elektrische Kontaktierung der Steuereinrichtung auf der Platine gesichert.Advantageously, the board of the control device bores, which are arranged such that the bores receive the connecting bolts of the heater in the installed state. This preferred embodiment ensures that the assembly can always be done without errors. For example, if the controller was to be mounted rotated 180 degrees, the terminal studs and the bosses would not match one another. As a result, the correct electrical contact of the control device is already secured on the board by the mechanical assembly.
Gemäß einer besonders bevorzugten Ausführungsform wird ein Durchlauferhitzer mit einer Steuereinrichtung und einem Heizblock bereitgestellt. Die Steuereinrichtung, welche eine Platine umfasst, wird direkt auf die Verbindungseinrichtung des Heizblocks vormontiert und mit Hilfe einer Verschraubung an die Anschlussbolzen der Heizeinrichtung befestigt. Durch die erfindungsgemäße Ausgestaltung der Platine der Steuereinrichtung kann die mechanische Montage bereits zum elektrischen Kontakt zwischen Steuereinrichtung und Heizeinrichtung führen. Durch die vormontierte Steuereinrichtung bevor der Durchlauferhitzer in einem Gehäuse untergebracht wurde, kann die elektrische Funktionalität getestet werden, da die Steuereinrichtung bereits zum Testen angeschlossen worden ist.According to a particularly preferred embodiment, a water heater is provided with a control device and a heating block. The control device, which comprises a circuit board, is directly pre-mounted on the connecting device of the heating block and fastened by means of a screw connection to the connecting bolts of the heating device. The inventive design of the board of the control device, the mechanical assembly can already lead to electrical contact between the control device and the heater. By the pre-assembled control device before the water heater has been housed in a housing, the electrical functionality can be tested because the controller has already been connected for testing.

Bei der nachfolgenden Beschreibung der vorliegenden Erfindung bezeichnen gleiche Bezugszeichen gleiche oder vergleichbare Komponenten.In the following description of the present invention, like reference characters designate like or similar components.
Die in der vorstehenden Beschreibung, den Ansprüchen und den Zeichnungen offenbarten Merkmale können sowohl einzeln als auch in beliebiger Kombination für die Verwirklichung der Erfindung in ihren verschiedenen Ausgestaltungen von Bedeutung sein.The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in any combination for the realization of the invention in its various forms.
Die Verbindungseinrichtung 30 ist gemäß dieser Ausführungsform mittels Anschlussbolzen 31 implementiert. Die Anschlussbolzen 31 durchlaufen die Kunststoffwand 11 des Heizblocks 10 und kontaktieren mechanisch und elektrisch die Heizeinrichtung bzw. die Heizwicklungen 50, welche innerhalb des Heizblocks 10 ebenfalls mäanderförmig in den Wasserkanälen 60 angeordnet sind. Die Heizwicklungen 50 verlaufen beispielsweise nur in den Wasserkanälen 60, welche nach
Mit Hilfe der Verbindungseinrichtung 30 bzw. der Anschlussbolzen 31 gemäß dieser Ausführungsform wird eine Steuereinrichtung 20 an den Heizblock 10 mechanisch und/oder elektrisch befestigt. Die Steuereinrichtung umfasst eine Platine 21, auf welcher unterschiedliche elektronische Bauelemente 40 angeordnet sind. Die Bauelemente 40 auf der Platine 21 werden mittels eines geeigneten Platinenlayouts auf der Platine elektrisch miteinander verbunden, um die gewünschte elektronische Funktionalität des Durchlauferhitzers bereitzustellen. Die Platine 21 weist eine Vielzahl von elektrischen Leiterbahnen (nicht abgebildet) auf, welche dem oben beschriebenen Platinenlayout entsprechen. Zu den wichtigsten elektronischen Bauelementen der Platine 21 gehört die Leistungselektronik 40, welche mit Hilfe der Leiterbahnen mit der Verbindungseinrichtung 30 in Kontakt steht. Gemäß dieser Ausführungsform besteht die Verbindungseinrichtung 30 aus metallischen Anschlussbolzen 31, welche innerhalb des Heizblocks 10 die Heizeinrichtung bzw. die Heizwicklungen 50 kontaktieren und außerhalb der Leiterbahnen der Platine 21 der Steuereinrichtung 20. Somit wird eine elektrisch/mechanische Verbindung zwischen der Heizeinrichtung bzw. den Heizwicklungen 50 und Steuereinrichtung 20 erreicht, ohne dass zusätzliche Verbindungskabel benötigt werden. Die Platine 21 bzw. die Steuereinrichtung 20 kann nur in einer Weise auf den Heizblock 10 befestigt werden, so dass keine Montagefehler entstehen können. Der Monteur bringt die Platine 21 auf die Anschlussbolzen 31 an und befestigt diese mechanisch, was wiederum automatisch zu einer elektrischen Kontaktierung der Leiterbahnen der Platine 21 führt. Die mit Hilfe der Anschlussbolzen 31 kontaktierten Leiterbahne können die elektrischen Signale der Leistungselektronik 40 übertragen, so dass die Heizwicklungen 50 entsprechend mit elektrischer Energie versorgt werden können. Es soll beachtet werden, dass die Leiterbahnen der Platine 21 entsprechend dimensioniert werden müssen, um elektrische Fehlfunktionen der Steuereinrichtung 30 zu vermeiden.With the aid of the connecting
Vorteilhafterweise ist die Leistungselektronik 40 der Steuereinrichtung 20 über dem kalten Bereich 70 des Heizblocks 10 angeordnet um beispielsweise eine verbesserte Kühlung der aktiven elektronischen Leistungsbauelementen 40 zu ermöglichen. Ferner kann durch den Verzicht weiterer elektrischer Verbindungskabel zwischen Steuereinrichtung 20 und Heizblock 10 bzw. Heizeinrichtung 50 ein besonders platzsparender Durchlauferhitzer hergestellt werden und Fehlmontage wie beispielsweise beim Anschließen elektrischer Verbindungskabel kann ausgeschlossen werden.Advantageously, the
Bevorzugt wurden Stützmittel 80 in der Kunststoffwand des Heizblocks 10 ausgebildet, welche zusätzlich die Steuereinrichtung 20 mechanisch stützen können. Das heißt, dass die Platine 21 auch in dem Bereich, wo keine Anschlussbolzen kontaktiert sind, sich nicht gegen die Wand 11 des Heizblocks 10 verbiegen kann. Es sind auch andere Ausgestaltungen der Stützmittel 80 denkbar, welche beispielsweise an der Unterseite der Steuereinrichtung 20 angebracht sind bzw. ausgebildet sein können. Folglich kann die Steuereinrichtung 20 bzw. die Platine 21 nicht während der Montage oder beim Testen oder desgleichen gegen die Kunststoffwand 11 des Heizblocks 10 verbogen bzw. gedrückt werden, und folglich werden Beschädigungen der Platine vermieden.Preferably, support means 80 were formed in the plastic wall of the
Die Platine 21 der Steuereinrichtung 20 weist eine Anschlussschnittstelle 22 auf, welche gemäß einer Ausführungsform in Form von Bohrungen in der Platine 21 ausgebildet ist. Die Bohrungen sind so angeordnet, dass die Leiterbahnen der Platine die Anschlussbolzen 31 elektrisch kontaktieren können. Die Bohrungen der Anschlussschnittstelle 22 sind so angeordnet, dass es nur eine Möglichkeit der Montage auf die Anschlussbolzen 31 des Heizblocks 10 gegeben ist. Somit kann eine elektrische Fehlinstallation vermieden werden, und bereits bei der mechanischen Befestigung kann die Platine 21 korrekt elektrisch an die Heizeinrichtung 50 angebunden werden. Gemäß dieser Ausführungsform der vorliegenden Erfindung sind die Bohrungen in der Platine 21 im Wesentlichen auf einer Linie angeordnet, jedoch sind andere Anordnungen für den Fachmann vorstellbar.The circuit board 21 of the
Ferner betrifft die vorliegende Erfindung einen Durchlauferhitzer, der einen Heizblock 10 und eine Steuereinrichtung 21 aufweist. Die Steuereinrichtung 20 kann mit Hilfe der Verbindungseinrichtung 30 bzw. der Anschlussbolzen 31 vormontiert auf den Heizblock 10 befestigt werden. Durch die Vormontage kann die elektrische Funktionalität des Durchlauferhitzers bereits in einer frühen Montagephase getestet werden, um somit nachträgliche Umbaukosten zu vermeiden. Durch die besondere Ausformung der Anschlussschnittstelle 22 der Platine 21 der Steuereinrichtung 20 gibt es praktisch nur eine Möglichkeit der Anbringung auf den Heizblock 10.Furthermore, the present invention relates to a water heater, which has a
Durch die elektrisch direkte Verbindung der Verbindungseinrichtung 30 des Heizblocks 10 mit der Steuereinrichtung 20 kann ohne weiter Verbindungskabel die elektrische Funktionalität des Durchlauferhitzers bzw. der Heizeinrichtung 50 gesichert werden, ohne dass Montagefehler bei einer elektrischen Kabelverbindung überhaupt entstehen können.Due to the electrically direct connection of the connecting
Die vorliegende Erfindung ist nicht auf Anwendungen im Bereich der Durchlauferhitzer eingeschränkt. Vielmehr können der erfindungsgemäße Heizblock und die erfindungsgemäße Steuereinrichtung bei anderen Warmwassergeräten verwendet werden, wie beispielsweise: Warmwasserspeichern, Boilern oder andere Warmwasseranlagen, welche dem Fachmann bekannt sind.The present invention is not limited to applications in the field of water heaters.
