Description

Die vorliegende Erfindung betrifft eine Blendeneinheit für einen Brenner, mit einer Blende und einem Träger für die Blende, welcher zwei die Blende tragende Seitenteile aufweist, die durch Befestigungsmittel, welche der Befestigung der Blendeneinheit im Brenner dienen, miteinander verbunden sind.The present invention relates to an orifice unit for a burner, with an orifice and a support for the orifice, which has two side parts which carry the orifice and which are connected to one another by fastening means which serve to fasten the orifice unit in the burner.

In der CH-A-654900 wird eine Blendeneinheit gezeigt, welche eine als kreisförmige Platte ausgebildete Blende mit einer zentralen Oeffnung für den Luftdurchtritt aufweist. Die Blende mit Halter ist mit Stützbeinen versehen, welche die Blende mit einer Buchse verbinden, die dazu dient, die Blendeneinheit mit einer Schraube auf der Düsenstange zu befestigen. Diese Blendeneinheit ist nicht sehr stabil. Die Stützbeine sind nur mit dem vorderen Teil der Buchse verbunden, so dass bereits relativ kleine Kräfte ausreichen, um diese Stützbeine zu verbiegen. Dadurch kommt die Blende inbezug auf die Düse exzentrisch zu liegen, was zu Funktionsstörungen des Brenners führt. Als Nachteil erweist sich auch die Notwendigkeit, die Zündelektroden an der Blende zu befestigen, denn dadurch wird das Auswechseln der Zündelektroden erschwert. Die bekannte Blendeneinheit ist relativ teuer in der Herstellung, weil die Buchse ein teures Drehteil ist und durch eine aufwendige Nietoperation mit den Stützbeinen verbunden werden muss.CH-A-654900 shows an orifice unit which has an orifice formed as a circular plate with a central opening for the passage of air. The cover with holder is provided with support legs that connect the cover with a socket that is used to fix the cover unit with a screw on the nozzle rod. This aperture unit is not very stable. The support legs are only connected to the front part of the socket, so that relatively small forces are sufficient to bend these support legs. This causes the orifice to be positioned eccentrically with respect to the nozzle, which leads to malfunction of the burner. The need to attach the ignition electrodes to the screen also proves to be a disadvantage, since this makes it difficult to replace the ignition electrodes. The known panel unit is relatively expensive to manufacture because the bushing is an expensive turned part and has to be connected to the support legs by a complex riveting operation.

Bei einem im Handel erhältlichen Brenner wird eine Blendeneinheit verwendet, bei der die Stützbeine Teile eines Trägers sind, welcher aus zwei Seitenteilen besteht, welche durch zwei in Abstand voneinander angeordnete Ringe miteinander verbunden sind. Die Verbindungsstellen der Seitenteile mit der Blende und den Ringen sind geschweisst. An einem der beiden Steitenteile ist ein Befestigungsblech angeschweisst, welches der Befestigung der Zündelektroden dient. Bei der Montage des Brenners wird die Blendeneinheit auf die Düsenstange gesteckt und durch eine Schraube an dieser festgeklemmt. Diese Blendeneinheit besteht aus relativ billigen Stanzteilen. Nachteilig ist jedoch der relativ grosse Herstellungsaufwand. Wie bereits erwähnt, werden die Ringe, die Seitenteile, das Befestigungsblech für die Zündelektroden und die Blende durch eine Vielzahl von Schweissstellen miteinander verbunden. Dies erfordert zunächst, dass die Teile vorgängig von Oel und Fettrückständen befreit werden, damit einwandfreie Schweissstelle entstehen können. In der Praxis hat sich aber gezeigt, dass trotz Vorreinigung der Teile die Schweissstellen des öfteren fehlerhaft sind und einer Beanspruchung nicht standhalten. Des weiteren ist nachteilig, dass die Teile vorgängig der Schweissoperation genau ausgerichtet werden müssen. Wegen der Vielzahl von Schweissstellen ist auch die abschliessende Kontrolle der fertiggestellten Einheit sehr aufwendig. Diese einzelnen Arbeitsschritte summieren sich zu einem beträchtlichen Arbeitsaufwand, den zu reduzieren von besonderer Bedeutung ist, weil die Blendeneinheit in relativ grossen Stückzahlen zur Verfügung gestellt werden muss.In a commercially available burner, an orifice unit is used in which the support legs are parts of a support which consists of two side parts which are connected to one another by two rings arranged at a distance from one another. The joints of the side parts with the cover and the rings are welded. A fastening plate is welded to one of the two parts of the step, which is used to fasten the ignition electrodes. When installing the burner, the panel unit is placed on the nozzle rod and clamped to it by a screw. This panel unit consists of relatively cheap stamped parts. The disadvantage, however, is the relatively large production outlay. As already mentioned, the rings, the side parts, the Mounting plate for the ignition electrodes and the panel connected to each other by a large number of welding points. First of all, this requires the parts to be freed of oil and grease residues beforehand so that a perfect weld can be created. In practice, however, it has been shown that despite pre-cleaning the parts, the welds are often defective and cannot withstand stress. Another disadvantage is that the parts must be precisely aligned prior to the welding operation. Because of the large number of welds, the final inspection of the finished unit is also very complex. These individual work steps add up to a considerable amount of work, which is of particular importance to reduce because the aperture unit has to be made available in relatively large numbers.

Es ist deshalb Aufgabe der vorliegenden Erfindung, eine Blendeneinheit zur Verfügung zu stellen, die einfacher, kostengünstiger und mit einem geringeren Arbeitsaufwand als die eingangs erwähnten Blendeneinheiten herzustellen ist. Die Verbindungen zwischen den einzelnen Teilen der Einheit sollten stabil sein, sodass keine Gefahr von Bruchstellen besteht. Es wäre zudem wünschenswert, wenn praktisch nach der Fabrikation praktisch keine Nachkontrolle mehr nötig wäre und die Blendeneinheit weitgehend automatisch hergestellt werden könnte.It is therefore an object of the present invention to provide an aperture unit which is simpler, less expensive and with less work to produce than the aperture units mentioned at the outset. The connections between the individual parts of the unit should be stable so that there is no risk of breakage. It would also be desirable if practically no follow-up inspection was practically necessary after production and the aperture unit could be manufactured largely automatically.

Dies wird erfindungsgemäss dadurch erreicht, dass die Befestigungsmittel durch einen U-förmigen Bügel gebildet sind, dessen Arme quer zur Längsachse der Blendeneinheit angeordnet sind, dass ein Arm des U-förmigen Bügels auf jeder Seite mindestens eine Einstecköffnung aufweist, in welcher ein Zapfen des Seitenteils eingreift, dass jeder Seitenteil mindestens eine Einstecköffnung aufweist, in welche ein Zapfen eingreift, der sich vom anderen Arm des U-förmigen Bügels seitlich nach aussen erstreckt, und dass die Blende mit den Seitenteilen verbunden ist. Da die Arme des Bügels quer zur Längsachse angeordnet sind, greifen die Zapfen der Seitenteile praktisch parallel zur Längsachse in die Einstecköffnungen am einen Arm des Bügels ein. Die Zapfen des anderen Arms des Bügels greifen dagegen quer zur Längsachse der Blendeneinheit in die Seitenteile ein und verhindern so, dass die Zapfen der Seitenteile aus den Einstecköffnungen des erstgenannten Arms bewegt werden können. Nach dem Zusammenbau der Teile, also sobald die Seitenteile mit der Blende verbunden sind, entsteht ein stabiles Gebilde. Es entfällt somit ein aufwendiges Reinigen und unsicheres Vereinigen von zusammenzuschweissenden Seitenteilen, wie dies einleitend beschrieben wurde. Auch sind keine Justier- und abschliessenden Kontrollarbeiten mehr nötig, da die geometrische Anordnung der Teile durch die Zapfen und Einstecköffnungen fest vorgegeben ist. Die Blendeneinheit kann daher durch angelerntes Personal zusammengebaut werden. Die Montage ist äusserst einfach. Die Seitenteile werden leicht schräge nach aussen geneigt in den U-förmigen Bügel gesteckt, dann gegeneinander nach innen verschwenkt, so dass die Zapfen des Bügels in die Einstecköffnungen der Seitenteile eingreifen, worauf das so entstandene Gebilde auf geeignete Art an der Blende befestigt wird. Diese Montage lässt sich bei grossen Stückzahlen auch automatisieren. Es ist zweckmässig, wenn die Seitenteile jeweils zwei in Abstand voneinander angeordnete Zapfen aufweisen, welche in entsprechende Einstecköffnungen am Arm eingreifen. Dies ergibt eine besonders stabile Anordnung.This is achieved according to the invention in that the fastening means are formed by a U-shaped bracket, the arms of which are arranged transversely to the longitudinal axis of the panel unit, and that one arm of the U-shaped bracket has at least one insertion opening on each side, in which a pin of the side part engages that each side part has at least one insertion opening into which a pin engages, which extends laterally outwards from the other arm of the U-shaped bracket, and that the cover is connected to the side parts. Since the arms of the bracket are arranged transversely to the longitudinal axis, the pins of the side parts engage practically parallel to the longitudinal axis in the insertion openings on one arm of the bracket. The pins of the other arm of the bracket, on the other hand, engage in the side parts transversely to the longitudinal axis of the diaphragm unit and thus prevent the pins of the side parts from being able to be moved out of the insertion openings of the first-mentioned arm. After assembling the parts, i.e. as soon as the side parts are connected to the panel, a stable structure is created. There is thus no need for time-consuming cleaning and unsafe joining of side parts to be welded together, as was described in the introduction. Also, no adjustment and final inspection work is necessary, since the geometrical arrangement of the parts is fixed by the pins and insertion openings. The panel unit can therefore be assembled by trained personnel. The assembly is extremely simple. The side parts are slanted slightly inclined outwards into the U-shaped bracket, then pivoted towards each other inwards so that the pins of the bracket engage in the insertion openings of the side parts, whereupon the resulting structure is fastened to the panel in a suitable manner. This assembly can also be automated for large quantities. It is expedient if the side parts each have two pins which are arranged at a distance from one another and which engage in corresponding insertion openings on the arm. This results in a particularly stable arrangement.

Im Gegensatz zu den Stützbeinen der Blendeneinheit gemäss der CH-A-654 900, welche lediglich an einer Stelle mit dem vorderen Teil der Befestigungsbuchse verbunden sind, sind die Seitenteile der erfindungsgemässen Blendeneinheit nicht nur mit einem Arm sondern mit beiden Armen des U-förmigen Bügels verbunden, welcher der Befestigung der Blendeneinheit dient. Die Seitenteile können daher nicht leicht verbogen werden. Somit besteht auch keine Gefahr, dass die Blende exzentrisch zur Brennerachse zu liegen kommt. Vorteilhaft ist auch, dass der U-förmige Bügel als Träger für die Zündelektrode dienen kann. Dadurch wird deren Auswechslung bei Servicearbeiten erleichtert.In contrast to the support legs of the panel unit according to CH-A-654 900, which are only connected at one point to the front part of the fastening bushing, the side parts of the panel unit according to the invention are not only with one arm but with both arms of the U-shaped bracket connected, which is used to attach the panel unit. The side parts can therefore not be bent easily. There is therefore no risk that the orifice will be positioned eccentrically to the burner axis. It is also advantageous that the U-shaped bracket can serve as a carrier for the ignition electrode. This makes it easier to replace them during service work.

Vorteilhaft weisen die Seitenteile Zapfen auf, welche in Einsteckschlitze der Blende steckbar sind, wobei eine Fixierung z.B. durch Verdrehen oder Vernieten der Zapfen erfolgen kann. Dadurch können die Seitenteile ebenfalls ohne Schweissen mit der Blende verbunden werden. Zweckmässigerweise weisen die Arme des U-förmigen Bügels in der Längsachse des Brenners jeweils eine Oeffnung auf, welche der Befestigung der Blendeneinheit im Brenner dient. Die Blendeneinheit kann auf die Düsenstanger das Lager für einen rotierenden Vergaser oder einen Support aufgesteckt werden. Die Seitenteile weisen zweckmässigerweise eine Gewindebohrung auf, in welche eine Schraube zur Fixierung der Blendeneinheit eindrehbar ist. Die Blendeneinheit lässt sich dadurch einfach und schnell im Brenner befestigen.The side parts advantageously have pins which can be inserted into the slot of the panel, with a fixation for example by twisting or riveting the pins. As a result, the side parts can also be connected to the panel without welding. The arms of the U-shaped bracket expediently each have an opening in the longitudinal axis of the burner, which serves to fasten the diaphragm unit in the burner. The panel unit can be attached to the nozzle rod, the bearing for a rotating carburetor or a support. The side parts expediently have a threaded hole into which a screw for fixing the panel unit can be screwed. The panel unit can be quickly and easily attached to the burner.

Vorteilhaft weisen die Seitenteile abgewinkelte Flügel auf. Dadurch werden die Seitenteile vertieft und zudem kann der Blendenträger in seinen Abmessungen relativ klein gehalten werden. Es verbleibt auch genügend Platz, um z.B. die Zündelektroden am Träger zu befestigen oder eine Brennstoffzuführungsleitung am Träger vorbei zu führen. Es ist zweckmässig, dass der Bügel einen Steg mit einer Gewindebohrung aufweist, um der Fixierung der Zündelektroden zu dienen. Die Schraube, mit welcher die Zündelektrode befestigt sind, ist leicht zugänglich, was das Auswechseln der Zündelektroden bei Servicearbeiten erleichtert. Es muss somit im Gegensatz zum vorbekannten Stand der Technik kein zusätzliches Halteblech an eines der Seitenteile geschweisst werden.The side parts advantageously have angled wings. As a result, the side parts are deepened and, in addition, the dimensions of the panel support can be kept relatively small. There is also enough space to e.g. to attach the ignition electrodes to the carrier or to pass a fuel supply line past the carrier. It is expedient for the bracket to have a web with a threaded bore in order to fix the ignition electrodes. The screw with which the ignition electrode is attached is easily accessible, which makes it easier to replace the ignition electrodes during service work. In contrast to the known prior art, no additional holding plate has to be welded to one of the side parts.

Die Figuren 1 bis 5 zeigen eine erfindungsgemässe Blendeneinheit 11, welche aus einer Blende 13 und einem Blendenträger 18 mit zwei identischen Seitenteilen 15 und einem U-förmigen Bügel 17 besteht. Im Gegensatz zum Stand der Technik sind die Einzelteile des Blendenträgers einfach zusammengesteckt. Dies wird dadurch erreicht, dass ein U-förmiger Bügel 17 die Seitenteile 15 verbindet. Der Bügel 17 weist an einem Arm 19 Einstecköffnungen 23 auf, in welche die Zapfen 27 der Seitenteile 15 eingreifen können. Der andere Arm 21 des Bügels 17 weist an den Seitenkanten jeweils einen Zapfen 25 auf, welcher in eine Einstecköffnung 29 am Seitenteil 15 eingreift. Zur Montage des Blendenträgers werden die Zapfen 27 in die Einstecköffnungen 23 gesteckt und die Seitenteile 15 anschliessend gegen den Bügel 17 geschwenkt, sodass die Zapfen 25 ebenfalls in die Einstecköffnungen 29 eingreifen. Nach der Fixierung der Seitenteile 15 an der Blende 13 sind die Seitenteile 15 mittels des Bügels 17 fest miteinander verbunden und bilden so den Blendenträger 18.Figures 1 to 5 show a panel unit 11 according to the invention, which consists of a panel 13 and a panel carrier 18 with two identical side parts 15 and a U-shaped bracket 17. In contrast to the prior art, the individual parts of the panel support are simply put together. This is achieved in that a U-shaped bracket 17 connects the side parts 15. The bracket 17 has on one arm 19 insertion openings 23 into which the pins 27 of the side parts 15 can engage. The other arm 21 of the bracket 17 has a pin 25 on the side edges, which engages in an insertion opening 29 on the side part 15. To assemble the panel support, the pins 27 are inserted into the insertion openings 23 and the side parts 15 are then pivoted against the bracket 17, so that the pins 25 also engage in the insertion openings 29. After the side parts 15 have been fixed to the panel 13, the side parts 15 are firmly connected to one another by means of the bracket 17 and thus form the panel carrier 18.

Zur Befestigung des Blendenträgers 18 an der Blende 13 weisen die Seitenteile 15 Zapfen 33 (Fig.2) auf, welche in Einsteckschlitze 35 an der Blende 13 eingreifen. Wie aus den Figuren 1,3,4b,c ersichtlich ist, haben die Seitenteile 15 abgewinkelte Flügel 31. Die Zapfen 33 werden, nachdem sie in die Einsteckschlitze 35 gesteckt worden sind, durch Umbiegen oder durch Verdrehen mit einer Zange oder einem Spezialwerkzeug an der Blende 13 fixiert. Die Blendeneinheit lässt sich somit ohne Justier-, Schweiss- und Kontrollarbeiten zusammenbauen.To fasten the panel support 18 to the panel 13, the side parts 15 have pins 33 (FIG. 2) which engage in insertion slots 35 on the panel 13. As can be seen from FIGS. 1, 3, 4b, c, the side parts 15 have angled wings 31. The pins 33, after they have been inserted into the insertion slots 35, are bent or twisted with pliers or a special tool fixed to the aperture 13. The panel unit can thus be assembled without adjustment, welding and inspection work.

Die Arme 19,21 des Bügels 17 weisen je eine Oeffnung 41,41' auf, welche der Befestigung der Blenden- oder Stauscheibeneinheit 11 im Brenner dient. Die Blendeneinheit 11 kann mittels der Oeffnungen 41,41' auf eine in der Längsachse des Brenners sich erstreckende Düsenstange oder dergleichen gesteckt und anschliessend durch eine Schraube, welche in eine Gewindebohrung 43 am Seitenteil 15 eingedreht wird, fixiert werden.The arms 19, 21 of the bracket 17 each have an opening 41, 41 ', which is used to fasten the diaphragm or baffle plate unit 11 in the burner. The aperture unit 11 can be plugged into a nozzle rod or the like extending in the longitudinal axis of the burner by means of the openings 41, 41 'and then fixed by means of a screw which is screwed into a threaded bore 43 on the side part 15.

Der die beiden Arme 19,21 verbindende Steg 37 des Bügels 17 kann der Fixierung von für den Betrieb des Brenners nötigen Zuleitungen, z.B. der Zündelektroden, dienen. Zu diesem Zweck ist der Steg 37 als Befestigungsplatte ausgebildet und weist eine Gewindebohrung 39 für eine Schraube (nicht dargestellt) auf. Die von einer Isolation umgebenen Zündelektroden können mittels eines Halteplättchens direkt an der Blendeneinheit fixiert werden.The web 37 of the bracket 17 connecting the two arms 19, 21 can be used to fix the supply lines necessary for the operation of the burner, e.g. the ignition electrodes. For this purpose, the web 37 is designed as a fastening plate and has a threaded bore 39 for a screw (not shown).
