Die Erfindung bezieht sich auf Hilfsbrenner, wie sie in selbsttätigen Wassererhitzern zur Aufrechterhaltung der Verbrennung einer verhältnismäßig geringen Gasmenge während des Nichtgebrauchs des Erhitzers Verwendung finden, zu dem Zweck, das den Hauptbrennern selbsttätig zugeführte Gas zu entzünden, sobald Wasser erhitzt werden soll.The invention relates to auxiliary burners as used in automatic water heaters to maintain the combustion of a relatively small amount of gas during when the heater is not in use, for the purpose that the main burners to ignite automatically supplied gas as soon as water is to be heated.

Der Zweck der Erfindung besteht haupt-The purpose of the invention is mainly

to sächlich darin, die Hilfsbrenner für selbsttätige Wassererhitzer dadurch einfacher, billiger und dauerhafter zu machen, daß der Brenner körper und der über diesem angebrachte Kopf aus einem Stück feuerfesten Materials hergestellt wird. Die Hilfsbrenner bilden zwar bei selbsttätigen Wassererhitzern nur ein einfaches und verhältnismäßig unwesentliches Glied. Jedoch zeigt die Praxis, daß es einerseits sehr schwer ist, einen solchen Hilfsbrenner so auszubilden, daß er ständig wirksam ist, andererseits ist ja der Betrieb des selbsttätigen Wassererhitzers von der guten Wirkung dieses Hilfsbrenners abhängig. Die bisher bekannten HilfsbrennerThe main thing is that the auxiliary burners for automatic water heaters are simpler and cheaper and to make the burner body and the one above it more durable Head is made from a piece of refractory material. The auxiliary burners form with automatic water heaters just a simple and relatively insignificant link. However, practice shows that on the one hand it is very difficult to train such an auxiliary burner so that it is constantly is effective, on the other hand, the operation of the automatic water heater is from the good effect of this auxiliary burner depends. The previously known auxiliary burners

"25 bestehen gewöhnlich aus drei Teilen, und zwar aus einem unteren Gußkörper, der mit dem Gaszuführungsrohr verbunden ist, einem mittleren, aus Porzellan hergestellten Teil, der eine Anzahl Gasaustrittsöffnungen hat, und einem oberen Metallkopf, der mittels einer Schraube festgehalten wird. Diese Ausführung hat sich jedoch praktisch nicht bewährt, einerseits wegen ihrer zu teuren Herstellung, andererseits wegen der geringen Haltbarkeit. Der Metallkopf wurde durch die Wirkung des im Gas vorhandenen Kohlenstoffes bei hoher Temperatur bald zerstört, die Schraube brannte fort, und ebenso platzte der mittlere Porzellankörper sehr schnell, wurde dadurch wertlos, so daß häufig Ersatzstücke angebracht werden mußten. _;._v ■"25 usually consist of three parts, namely a lower cast body which is connected to the gas supply pipe, a central part made of porcelain which has a number of gas outlet openings, and an upper metal head which is held in place by means of a screw. This version However, it has not proven itself in practice, on the one hand because it is too expensive to manufacture and on the other hand because of its low durability. The metal head was soon destroyed by the effects of the carbon in the gas at high temperatures, the screw burned away, and the middle porcelain body also burst very quickly , became worthless, so that replacement pieces often had to be attached. _; . _v ■

Diese Nachteile werden durch die den Gegenstand der Erfindung bildende Ausführung des Hilfsbrenners vermieden.These disadvantages are alleviated by the embodiment forming the subject of the invention of the auxiliary burner avoided.

Die Erfindung ist auf der Zeichnung dargestellt, und zwar istThe invention is illustrated in the drawing, namely is

Fig. ι ein senkrechter Schnitt durch einen Hilfsbrenner nach der Erfindung,Fig. Ι a vertical section through an auxiliary burner according to the invention,

Fig. 2 ein wagerechter Schnitt durch den Brenner nach der Linie X-X der Fig. 1 undFig. 2 is a horizontal section through the burner along the line XX in Fig. 1 and

Fig, 3 ein senkrechter Schnitt durch eine abgeänderte Ausführung.3 is a vertical section through a modified embodiment.

Der neue Hilfsbrenner besteht aus dem zylindrischen Körper ι und dem Kopf 2, der wesentlich größeren Durchmesser wie der Körper ι hat, jedoch sind beide aus einem einzigen Stück feuerfesten Materials, wie z. B. aus Seifenstein, feuerfestem Ton, Porzellan oder einer Graphitmischung hergestellt. Der zylindrische Körper 1 ist mit 'einer mittleren Bohrung 3 versehen, von welcher dicht unter dem Kopf 2 eine Anzahl radial stehender Kanäle 3^a abzweigt, die an der Peripherie ausmünden und die Brenneröffnungen darstellen. Der Kopf 2 hat zweckmäßig konische Gestalt, und sein Durchmesser ist so viel größer, als derjenige des zylindrischen Körpers 1 ist, daß Niederschlagwasser oder auf den Brenner her-The new auxiliary burner consists of the cylindrical body ι and the head 2, which has a much larger diameter than the body ι, but both are made of a single piece of refractory material, such as. B. made of soap stone, refractory clay, porcelain or a graphite mixture. The cylindrical body 1 is provided with a central bore 3 from which a number of radially standing channels 3 ^a branch off just below the head 2, which open out at the periphery and represent the burner openings. The head 2 expediently has a conical shape and its diameter is so much larger than that of the cylindrical body 1 that rainwater or the burner

Claims

dripping off water and prevented the same from entering the burner openings will. The cylindrical body ι has a screw thread ι "on the outer wall, on which a sleeve 5 is screwed to accommodate a short nipple or Pipe section 4 is used, which is in communication with the gas supply pipe. For sealing can between the sleeve 5 and the lower edge of the cylindrical body 1 a sealing ring 6 can be arranged.

The modification of the invention shown in FIG. 3 corresponds essentially to the embodiment shown in FIGS. 1 and 2 and only differs from the latter in that the sleeve 5 and the screw thread ι "provided on the outer periphery of the burner body 1 are omitted. this screw thread is instead arranged in the interior at the lower end of the gas line 3 and serves for screwing the nipple 4. the sealing ring 6 is thereby secured ^α between the bottom of the body 1 and, arranged on the nipple ring 4. 4

When this auxiliary burner is in operation, the gas coming from the line flows through the nipple 4 into the central bore 3 in order to flow out at the burner opening 3 ^a . Here the gas is ignited in a known manner.

Because the head of the burner is made of the same refractory material as the burner body itself, it cannot be destroyed by the heat generated during operation of the main burner. On the other hand you can but also .the burner openings through soot or other foreign components that are otherwise lightly stick to the metal head, do not get clogged. The burner itself can can easily be put on and taken off ^ but is otherwise so in its construction simple and strong that breaking and destroying is almost impossible.

It should also be noted that the manufacture of auxiliary burners to ignite the main flame in the case of gas incandescent lamps and gas stoves made from one piece of ■ fireproof material is common. The invention therefore consists only in the manufacture of the burner body and the head attached above it for draining the rainwater from a piece of refractory material Auxiliary burners for automatic water heaters.

Ρλ τ \ ι ν τ - AN sr κ ü c 11 ε:

ι. Auxiliary burner for automatic water heaters with a suitably conical head arranged on the burner body, characterized in that the burner body (1) and the one used to drain the rainwater conical head (2) consist of a single piece of refractory material.

2. auxiliary burner according to claim 1, characterized characterized in that on the burner body (1) provided on the outer periphery with screw thread, a sleeve (5) is screwed on, which on the one hand serves to accommodate the gas supply nipple, on the other hand, a sealing washer (6) presses against the bottom of the burner body.

3. Embodiment of the auxiliary burner according to claims 1 and 2, thereby characterized in that the pipe nipple (4), which is provided with screw thread middle hole (3) of the burner body (1) is screwed in, a washer (4 ") carries, which presses a sealing ring against the bottom of the burner body.
