Abstract

The arrangement has a base plate (7) of a casing with a slit (18), into which a casing (17) with an undercut can be slid. The casing is preferably formed as a slim oblong, which has two ribs at one end with an intermediate groove, in which the bevelled edges of the slit engage. An additional seal (29) may be fitted in the groove.

Description

Die vorliegende Erfindung bezieht sich auf eine Anordnung zur Halterung eines Gehäuses gemäß dem einleitenden Teil des unabhängigen Anspruchs.The present invention relates to an arrangement for holding a housing according to the introductory part of the independent claim.

Solche Halterungen sind bereits bei marktgängigen Wasserheizem der Patentinhaberin bekanntgeworden, wobei diese Gehäuse mit Gewinden versehene Befestigungsvorsprünge aufwiesen, mit denen die Gehäuse an einem Element des Wasserheizers mit Schrauben befestigt wurden. Diese Art der Montage beinhaltet eine Reihe von Arbeitsgängen lediglich für das Ausführen der Befestigung, zu denen noch der Montageaufwand hinzukommt. Der vorliegenden Erfindung liegt mithin die Aufgabe zugrunde, eine Anordnung zur Halterung der eingangs näher bezeichneten Art anzugeben, die sich erheblich billiger in die Fertigung umsetzen läßt.Such mounts are already on the market-owned water heater from the patent owner become known, these housings with threaded fastening projections with which the housing on an element of the water heater with screws were attached. This type of assembly only involves a series of operations for carrying out the fastening, to which the assembly effort is added. The The present invention is therefore based on the object of an arrangement for holding the Specify initially specified type, which is significantly cheaper to manufacture can be implemented.

Die Lösung dieser Aufgabe liegt bei einer Anordnung zur Halterung der eingangs bezeichneten Art erfindungsgemäß in den kennzeichnenden Merkmalen des unabhängigen Anspruchs.The solution to this problem lies in an arrangement for holding the input designated type according to the invention in the characterizing features of the independent Claim.

Hieraus resultiert der überraschende Vorteil, daß bei entsprechender Ausbildung des Gehäuseteils und des Gehäuses ein einfaches Einschieben des Gehäuses in die Aussparung des Gehäuseteils ermöglicht wird. Eine Sicherung des Gehäuses gegen Herausfallen ist dann durch ein anderes beliebiges Teil möglich, das im Zuge seiner Anordnung dann vor die Aussparung im Gehäuseteil gesetzt wird, so daß es dem Gehäuse unmöglich ist, aus dem Schlitz herauszugleiten.This results in the surprising advantage that with appropriate training of the Housing part and the housing a simple insertion of the housing in the Recess of the housing part is made possible. Securing the housing against Falling out is then possible by any other part, which in the course of its Arrangement is then placed in front of the recess in the housing part so that it is the housing it is impossible to slide out of the slot.

Weitere Ausgestaltungen und besonders vorteilhafte Weiterbildungen der Erfindung gehen aus den abhängigen Ansprüchen sowie einem Ausführungsbeispiel der Erfindung hervor, das nachfolgend anhand der Fig. 1 bis 4 der Zeichnung näher erläutert wird.Further refinements and particularly advantageous developments of the invention go from the dependent claims and an embodiment of the invention, which is explained in more detail below with reference to FIGS. 1 to 4 of the drawing.

    Ein gasbeheizter Durchlauferhitzer 1 weist ein Gehäuse 2 auf, das aus zwei einen Innenraum 3 einschließenden Seitenwänden 4 und 5 sowie einem Deckel 6 und einem Bodenblech 7 besteht. Nach vom zum Betrachter hin wird der Innenraum 3 des Gehäuses durch ein nicht dargestelltes Frontblech abgedeckt, das in Schraublöchern 8 der Seitenteile 4 und 5 gehalten ist. Der Innenraum 3 des gasbeheizten Durchlauferhitzers 1 nimmt einen Wärmetauscher 9, einen Gasbrenner 10, einen Abgasventilator 11 mit dessen Lüftermotor 12 sowie ein dem Brenner 10 zugeordnetes Gasverteilrohr 13 und ein Gaszufuhrrohr 14 auf. A gas-fired instantaneous water heater 1 has a housing 2, which consists of two ones Interior 3 including side walls 4 and 5 and a lid 6 and one Floor plate 7 is made. Towards the viewer, the interior 3 of the housing covered by a front plate, not shown, in the screw holes 8 of the side parts 4 and 5 is held. The interior 3 of the gas-fired instantaneous water heater 1 takes one Heat exchanger 9, a gas burner 10, an exhaust gas fan 11 with its fan motor 12 and a gas distribution pipe 13 assigned to the burner 10 and a gas supply pipe 14.

    Dieses Gaszufuhrrohr durchdringt das Bodenblech 7 im Zuge einer ersten Aussparung 15, in die eine Dichtung 16 eingeschoben ist, die den rund um das Gaszufuhrrohr 14 verbleibenden Raum der Aussparung 15 abdichtet.This gas supply pipe penetrates the base plate 7 in the course of a first recess 15, into which a seal 16 is inserted which surrounds the gas supply pipe 14 remaining space of the recess 15 seals.

    Wie Fig. 1 verdeutlicht, ist ein Gehäuse 17 in einen Schlitz 18 im Bodenblech 7 eingeschoben. Dieses Gehäuse 17 enthält Teile einer Steuer- und Regelschaltung. Wie die Fig. 2 verdeutlicht, durchsetzen ein Kaltwassereinlaßrohr 19 und ein Warmwasserauslaßrohr 20 das Bodenblech 7. Die Aussparungen 15 und 18 sind als randoffene Ausnehmungen ausgebildet, wobei die offene Seite der Vorderwand zugewandt ist.As illustrated in FIG. 1, a housing 17 is in a slot 18 in the base plate 7 inserted. This housing 17 contains parts of a control and regulating circuit. As the Fig. 2 illustrates, enforce a cold water inlet pipe 19 and a hot water outlet pipe 20 the bottom plate 7. The recesses 15 and 18 are open-ended recesses formed with the open side facing the front wall.

    Die Fig. 3 zeigt nun eine Ansicht von unten auf das Bodenblech 7, man erkennt sowohl die Aussparung 15 wie auch den Schlitz 18, zwischen denen ein Steg verbleibt. Ausnehmung 15 und Schlitz 18 sind im Mündungsbereich 22, der der Gerätevorderseite zugewandt ist, offen. Die dem Kaltwasserrohr 19 und dem Warmwasserrohr 20 zugeordneten Löcher 23, die an der Rückwand des Gerätes liegen, sind gleichfalls gut zu erkennen.Fig. 3 now shows a view from below of the bottom plate 7, you can see both the Recess 15 as well as the slot 18, between which a web remains. Recess 15 and slot 18 are open in the mouth region 22, which faces the front of the device. The holes 23 assigned to the cold water pipe 19 and the hot water pipe 20, which the rear wall of the device are also clearly visible.

    Längs ihrer beiden den freigeschnittenen Teil begrenzenden Wände 24 und 25 sind sowohl Aussparung wie auch der Schlitz abgekantet. Dadurch erhält auch der Steg 21 eine gewisse Eigensteifigkeit.Along their two walls 24 and 25 delimiting the cut-out part are both Cut-out as well as the slot. This also gives the web 21 a certain amount Inherent rigidity.

    In den Schlitz 18 wird nun ein im wesentlichen vierkantquaderförmiges Gehäuse 17, das Elemente einer Meß-, Regel- und Steuerschaltung aufweist, eingeschoben. Hierzu weist der Kopf 24 des Quaders 2 ringsum angeordnete Rippen 25 auf, die zwischen sich eine Nut 26 freilassen. In diese Nut werden nun die abgekanteten Ränder 24 und 25 des Schlitzes 18 eingeschoben. Damit liegt das Gehäuse dreiseitig bezüglich des Bodenblechs 7 fest. Die einzige Bewegungsmöglichkeit besteht dann, daß das Gehäuse nach vom aus dem Schlitz herausgleiten kann. Hieran wird es allerdings durch das in den Fig. 1 und 3 nicht dargestellte Frontabdeckblech gehindert. Statt auf dem ansonsten glatten Mantel 27 des Gehäuses 17 zwei im Abstand voneinander liegende Rippen 25 anzuformen, wäre es auch möglich, bei entsprechender Dicke des Gehäuses 17 lediglich die Nut 26 einzuarbeiten. Diese Lösung wäre zwar technisch gleichwertig, hätte aber den Nachteil, daß das Gehäuse an den nicht benötigten Stellen unnütz viel Material aufweisen müßte.In the slot 18 is now a substantially square cuboid housing 17, the Has elements of a measuring, regulating and control circuit inserted. The Head 24 of the cuboid 2 ribs 25 arranged all around, with a groove 26 between them set free. The bent edges 24 and 25 of the slot 18 are now in this groove inserted. The housing is thus fixed on three sides with respect to the base plate 7. The the only possibility of movement is then that the housing from the slot can slide out. This is, however, due to that which is not shown in FIGS. 1 and 3 Front cover plate hindered. Instead of on the otherwise smooth jacket 27 of the housing 17th To form two spaced-apart ribs 25, it would also be possible to appropriate thickness of the housing 17 only to incorporate the groove 26. This solution would be technically equivalent, but would have the disadvantage that the housing on the needed places would have uselessly a lot of material.

    Wesentlich ist, daß die beiden Rippen 25 zusammen mit der Nut 26 eine Hinterschneidung darstellen, die einen Widerstand gegen eine Bewegung des einzuschiebenden Gehäuses senkrecht zu dieser Nut darstellt.It is essential that the two ribs 25 together with the groove 26 an undercut represent a resistance to movement of the housing to be inserted perpendicular to this groove.

    Das Bodenblech 7 bildet das Gehäuseteil, an dem das zu lagernde Gehäuse einschiebbar befestigt werden soll. Statt eines Bodenblechs käme auch das Deckblech oder ein senkrecht angeordnetes Seitenblech in Frage.The bottom plate 7 forms the housing part on which the housing to be stored can be inserted to be attached. Instead of a floor plate, there would also be the cover plate or a vertical one arranged side panel in question.

    Die Fig. 5 zeigt das Bodenblech 7 in einer perspektivischen Ansicht von unten, hier sind die Abkantungen 26 und 27 an den Rändern des Schlitzes und der Aussparung gut zu erkennen.Fig. 5 shows the bottom plate 7 in a perspective view from below, here are the Bends 26 and 27 on the edges of the slot and the recess well detect.

    Im Steg 26 kann eine zusätzliche Dichtung 29 oder ein Dichtungsprofil angebracht sein, wodurch die notwendige Dichtheit der Verbrennungskammer erreich t wird (siehe Fig. 4).An additional seal 29 or a sealing profile can be attached in the web 26, whereby the necessary tightness of the combustion chamber is achieved (see Fig. 4).
