Description

Die Erfindung betrifft ein Heizgerät zum Erwärmen eines Wärmeträgermediums zur Beheizung eines Gebäudes oder zum Bereitstellen von Warmwasser auf Basis der Verbrennung eines Brennstoffs.The invention relates to a heater for heating a heat transfer medium for heating a building or for providing hot water based on the combustion of a fuel.

Aus der Patentanmeldung DE 10 2006 036 471 A1 ist ein gattungsgemäßes Heizgerät mit einem ein Ansaugrohr umfassenden Ansaugsystem stromauf des Verbrennungsluft-Gebläses bekannt. Ansaugrohre sind grundsätzlich bekannt, um das Verbrennungssystem akustisch zu verstimmen und so die Schallemissionen zu senken. Es wird vorgeschlagen, die Wirkung des Ansaugrohrs zu verbessern durch Einbringen von scharfkantigen Umlenkungen, Bohrungen und elastische Materialien in das Ansaugrohr.From the patent application DE 10 2006 036 471 A1 For example, a generic heater with an intake manifold comprising an intake manifold is known upstream of the combustion air blower. Intake pipes are basically known in order to acoustically detune the combustion system and thus reduce the noise emissions. It is proposed to improve the effect of the intake pipe by introducing sharp-edged deflections, holes and elastic materials in the intake manifold.

Wie alle Ansaugrohre fester Dimensionen hat auch dieses Ansaugrohr den Nachteil, dass es seine beste Wirkung in einem eingeschränkten Betriebsparameter-Bereich entfaltet. Daher werden in der Regel für bestimmte Heizgeräte jeweils Sätze von mehreren Ansaugrohren bereitgehalten, mit denen das Ansaugsystem durch Austausch des Ansaugrohrs entsprechend den Randbedingungen akustisch angepasst werden kann. Zudem ist das Ansaugrohr grundsätzlich als zusätzliches Bauteil vorzusehen und erhöht die Komplexität und die Kosten des Heizgeräts.Like all fixed-size intake pipes, this intake pipe also has the disadvantage of exhibiting its best effect in a restricted range of operating parameters. Therefore, in each case sets of several intake pipes are usually kept ready for certain heaters, with which the intake system can be acoustically adjusted by replacing the intake pipe according to the boundary conditions. In addition, the intake pipe is basically to be provided as an additional component and increases the complexity and cost of the heater.

Es ist daher Aufgabe der Erfindung, ein Heizgerät mit einem Ansaugsystem bereitzustellen, das die vorgenannten Nachteile vermeidet.It is therefore an object of the invention to provide a heater with an intake system which avoids the aforementioned disadvantages.

Diese Aufgabe wird gemäß den Merkmalen des Anspruchs 1 dadurch gelöst, dass das Ansaugsystem ein geteiltes Außengehäuse aufweist, in dem ein Hohlraum vorgesehen ist. In diesem Hohlraum kann mit Luftleitelementen ein Strömungskanal konfiguriert werden. Durch Hinzufügen und Entfernen der Luftleitelemente oder durch Veränderung der Positionen können Strömungskanäle unterschiedlicher Länge leicht konfiguriert werden, ohne dass Teile komplett ausgewechselt werden müssen. So kann das Heizgerät für bestimmte Einsatzzwecke vorkonfiguriert werden. Bei der Inbetriebnahme kann dann vom Fachhandwerker eine Anpassung an die tatsächliche Installationsumgebung vorgenommen werden, ohne dass ein neues Ansaugrohr verwendet werden muss.This object is achieved according to the features of claim 1, characterized in that the intake system has a split outer housing in which a cavity is provided. In this cavity can be configured with air guide elements, a flow channel. By Adding and removing the air vanes or changing the positions makes it possible to easily configure flow ducts of different lengths without requiring complete replacement of parts. This allows the heater to be preconfigured for specific applications. During commissioning, the specialist tradesman can adapt to the actual installation environment without having to use a new intake pipe.

In einer Ausführungform ist das Außengehäuse aus Schaummaterial, bevorzugt aus EPP. Ebenfalls die Luftleitelemente sind in einer Ausführungsform aus Schaummaterial, bevorzugt aus EPP.In one embodiment, the outer housing is made of foam material, preferably EPP. Likewise, in one embodiment, the air guiding elements are made of foam material, preferably of EPP.

Besonders bevorzugt ist das Ansaugsystem-Außengehäuse einstückig mit einer Fixierung für zumindest ein Aggregat des Heizsystems ausgebildet oder mit einer solchen Fixierung verbunden, wobei in die Fixierung ein Aggregat formschlüssig einlegbar und somit fixierbar ist, ohne beispielsweise mit der Aufnahme verschraubt zu werden. Derartige Aufnahmen sind bekannt aus der Patentanmeldung DE 10 2014 225 548.1 . Hierin wird ein Heizgerät mit Isoliermitteln beschrieben, in die die einzelnen Aggregate des Heizgeräts so eingelegt sind, dass die Aggregate durch die Isoliermittel formschlüssig fixiert werden. Erfindungsgemäß wird in der vorliegenden Erfindung das Ansaugsystem also direkt durch das Isoliermittel gebildet, wobei das Isoliermittel das Außengehäuse des Ansaugsystems ist, das den Hohlraum umschließt.Particularly preferably, the intake system outer housing is integrally formed with a fixation for at least one unit of the heating system or connected with such a fixation, in the fixation of an assembly can be inserted in a form-fitting manner and thus fixed, without being screwed, for example, with the recording. Such recordings are known from the patent application DE 10 2014 225 548.1 , Herein a heater is described with insulating means in which the individual units of the heater are inserted so that the units are positively fixed by the insulating means. According to the invention in the present invention, therefore, the intake system is formed directly by the insulating means, wherein the insulating means is the outer casing of the intake system, which encloses the cavity.

Die eingelegten Aggregate sind zumindest die Brenngas-Luft-Mischvorrichtung und/oder das Gebläse für die Zuführung der Verbrennungsluft zum Brenner.The inserted units are at least the fuel gas-air mixing device and / or the fan for supplying the combustion air to the burner.

Bevorzugt ist das Ansaugsystem so ausgebildet, dass die Verlustwärme der Pumpe zur Förderung eines Wärmeträgermediums zum Vorwärmen der Verbrennungsluft genutzt wird, indem diese an der Pumpe vorbeigeführt wird und so die Verlustwärme aufnimmt.Preferably, the intake system is designed so that the heat loss of the pump is used to promote a heat transfer medium for preheating the combustion air by being passed past the pump and so absorbs the heat loss.

Die Luftleitelemente können formschlüssig in den Hohlraum eingesteckt sein, kraftschlüssig geklemmt oder durch Kleben oder Schweißen stoffschlüssig verbunden sein.The air guide elements can be positively inserted into the cavity, clamped non-positively or materially connected by gluing or welding.

Die Erfindung wird nun anhand der Figuren detailliert erläutert.The invention will now be explained in detail with reference to FIGS.

Figur 1 stellt ein erfindungsgemäßes Absaugsystem mit geöffnetem und Figur 2 mit geschlossenem Außengehäuse dar. Das Absaugsystem besteht aus einem Absaugsystem-Außengehäuse 7, das zweiteilig ausgeführt ist und durch eine Trennfuge 14 geteilt ist. Im wesentlichen in der Trennebene weist das Absaugsystem-Außengehäuse 7 einen Hohlraum 9 auf, der einen Strömungskanal 8 bildet. In diesem Beispiel ist der Strömungskanal 8 nicht vollständig in der Trennebene vorgesehen. Erfindungsgemäß reicht es aus, wenn ein Teil des Hohlraums 9 in der Trennebene liegt, um dort Luftleitelementen 15 (in Figur 3 dargestellt) einbringen zu können. In Figur 1 ist ebenfalls in dem Ansaugsystem-Außengehäuse 7 die Brenngas-Luft-Mischvorrichtung 4 und das Gebläse 3 fixiert. Dazu weist das Ansaugsystem-Außengehäuse 7 Fixierungen 16 beispielsweise in Form von Taschen, Ausnehmungen oder Haltern auf, in denen die Aggregate formschlüssig fixiert werden. In dem hier dargestellten Beispiel muss das Ansaugsystem-Außengehäuse 7 die Brenngas-Luft-Mischvorrichtung 4 im Bereich des Lufteinlasses abdichtend umschließen, um eine ausschließliche Luftführung durch den Hohlraum 9 bzw. den Strömungskanal 8 sicherzustellen. FIG. 1 represents an inventive extraction system with open and FIG. 2 with closed outer housing. The suction system consists of a suction system outer housing 7, which is made in two parts and is divided by a parting line 14. Substantially in the parting plane, the exhaust system outer housing 7 has a cavity 9, which forms a flow channel 8. In this example, the flow channel 8 is not completely provided in the parting plane. According to the invention it is sufficient if a part of the cavity 9 is located in the parting plane in order there to air guiding elements 15 (in FIG. 3 shown) to bring. In FIG. 1 Also, in the intake system outer case 7, the fuel gas-air mixing device 4 and the blower 3 are fixed. For this purpose, the intake system outer housing 7 fixings 16, for example in the form of pockets, recesses or holders, in which the units are fixed in a form-fitting manner. In the example shown here, the intake system outer housing 7 must sealingly surround the fuel gas / air mixing device 4 in the region of the air inlet, in order to ensure an exclusive air flow through the cavity 9 or the flow channel 8.

In den Figuren 3 bis 5 ist dargestellt, wie erfindungsgemäß in dem Hohlraum 9 des Ansaugsystem-Außengehäuses 7 der Strömungskanal 8 gebildet wird. Dazu sieht das Ansaugsystem-Außengehäuse 7 Aufnahmen 10 vor, mit denen die Luftleitelemente 15 im Hohlraum 9 befestigt werden können. Dies kann, wie in dem Beispiel in Figur 3 dargestellt, formschlüssig erfolgen. Ebenfalls ist es möglich, die Luftleitelemente 15 kraftschlüssig zwischen den Gehäusehälften des Ansaugsystem-Außengehäuses 7 einzuklemmen oder durch Kleben oder Schweißen stoffschlüssig zu verbinden. Figur 4 und 5 zeigen zwei Varianten, in denen mit Luftleitelementen 15 in dem Hohlraum 9 ein Strömungskanal 8 gebildet wird. Die Darstellung entspricht einer Draufsicht der in Figur 1 gezeigten Variante. Zwischen den Gehäusehälften des Ansaugsystem-Außengehäuses ist ein G-förmiger Hohlraum 9 gebildet. In dem Beispiel in Figur 4 ist insgesamt ein kurzer Strömungskanal 8 ausgebildet. In dem Beispiel in Figur 5 ist mit Luftleitelementen 15 ein mäanderförmiger Strömungskanal 8 ausgebildet, der länger ist. Durch die Auswahl verschiedener Luftleitelemente an verschiedenen Positionen kann die Länge des Strömungskanals 8 erfindungsgemäß einfach und ohne Austausch eines Ansaugrohrs an die gewünschten Werte angepasst werden.In the FIGS. 3 to 5 is shown how according to the invention in the cavity 9 of the intake system outer housing 7 of the flow channel 8 is formed. For this purpose, the intake system outer housing 7 provides receptacles 10 with which the air guiding elements 15 can be fastened in the cavity 9. This can, as in the example in FIG. 3 shown, form-fitting. It is also possible to frictionally clamp the air guide elements 15 between the housing halves of the intake system outer housing 7 or to join them by adhesive bonding or welding. FIGS. 4 and 5 show two variants in which with air guide elements 15 in the cavity 9, a flow channel 8 is formed. The illustration corresponds to a plan view of FIG FIG. 1 shown variant. Between the housing halves of the intake system outer housing, a G-shaped cavity 9 is formed. In the example in FIG. 4 Overall, a short flow channel 8 is formed. In the example in FIG. 5 is formed with air guide elements 15 a meandering flow channel 8, which is longer. By selecting different air guide elements at different positions, the length of the flow channel 8 according to the invention can be easily adapted to the desired values without replacing an intake pipe.

Figur 6 stellt ein erfindungsgemäßes Heizgerät mit dem erfindungsgemäßen Ansaugsystem 6 dar. In diesem Heizgerät sind Aggregate wie der Brenner 5 und die Pumpe 17, mit der ein vom Brenner 5 beheiztes Wärmeträgermedium umgewälzt wird, in Fixierungen der Isolierung 11 formschlüssig fixiert. Zu den Fixierungen wird auf Figur 1 verwiesen. Aus Sicherheitsgründen weisen gebläseunterstützte Heizgeräte eine Unterdruckkammer auf, die dadurch gebildet wird, dass die Außenluft nicht direkt dem Gebläse 3 zugeführt wird, sondern zunächst in das Innere des Gehäuses geleitet wird und dann vom Gebläse 3 angesaugt wird. Dadurch wird ein Unterdruck im gesamten Gehäuse 2 des Heizgeräts 1 sichergestellt, so dass kein Gas aus dem Heizgerät 1 nach außen entweichen kann. In Figur 6 wird die Luft durch eine Luftzufuhr 19 durch einen Kanal in der Isolierung 11 in das durch das Gehäuse 2 umschlossene Heizgerät 1 geleitet. Dabei umströmt die Luft durch Kanäle 18 die Pumpe 17 und nimmt deren Verlustwärme auf. Anschließend strömt die Luft aufgrund des durch das Gebläse 3 hergestellten Druckgefälles durch den Strömungskanal 8 in dem Ansaugsystem-Außengehäuse in der zuvor beschriebenen Weise durch die Brenngas-Luft-Mischvorrichtung 4, wo es mit Brenngas vermischt wird, und durch das Gebläse 3 in den Brenner 5. Dabei kann das Ansaugsystem-Außengehäuse 7 einstückig mit der Isolierung 11 ausgeführt sein, mit dieser unmittelbar verbunden sein oder mittelbar über Halterungen mit dieser verbunden sein. FIG. 6 represents a heater according to the invention with the intake system 6 according to the invention. In this heater units such as the burner 5 and the pump 17, with a heated by the burner 5 heat transfer medium is circulated, fixed in form-locking fixations of the insulation 11. To the fixations will open FIG. 1 directed. For safety reasons, blower-assisted heaters have a vacuum chamber which is formed by the fact that the outside air is not supplied directly to the blower 3, but is first conducted into the interior of the housing and is then sucked in by the blower 3. Thereby, a negative pressure in the entire housing 2 of the heater 1 is ensured, so that no gas can escape from the heater 1 to the outside. In FIG. 6 the air is passed through an air supply 19 through a channel in the insulation 11 into the heater 1 enclosed by the housing 2. The air flows through channels 18, the pump 17 and absorbs their heat loss. Subsequently, the air flows due to the through the Blower 3 produced pressure gradient through the flow channel 8 in the intake system outer housing in the manner described above by the fuel gas-air mixing device 4, where it is mixed with fuel gas, and by the blower 3 in the burner 5. In this case, the intake system outer housing 7 be integral with the insulation 11, be directly connected to this or be indirectly connected via brackets with this.

Figur 7 stellt das in Figur 4 beschriebene Ansaugsystem dar, in dem ein zusätzlicher Dämpfer 12 vorgesehen ist. Dieser Dämpfer 12 kann aus einem porösem Material, einem Fließ oder einem gesinterten Körper bestehen. Durch den Dämpfer 12 wird zusätzlich das Auftreten von selbsterregten Schwingungen in dem Ansaugsystem 6 gedämpft. FIG. 7 put that in FIG. 4 described intake system in which an additional damper 12 is provided. This damper 12 may be made of a porous material, a flow or a sintered body. In addition, the occurrence of self-excited vibrations in the intake system 6 is damped by the damper 12.
