Abstract
Description
Die Erfindung betrifft eine Mischeinrichtung für einen Gasgebläsebrenner gemäß dem Oberbegriff des Schutzanspruchs 1.The The invention relates to a mixing device for a gas blower burner according to the preamble of claim 1 protection.
Eine
Mischeinrichtung der eingangs genannten Art ist nach der
Nach
der
Dieses eine, die Venturi-Düse enthaltende Bauteil, an dem zusätzlich noch das Gasregelgerät angeordnet ist, wird mittels eines Bajonettverschlusses am oben genannten Gebläsegehäuse befestigt, d. h. das Bauteil ist von diesem lösbar ausgebildet, was seinen Grund unter anderem darin hat, dass die Venturi-Düse aus Kunststoff und das Gebläsegehäuse aus Metall gebildet ist.This a, the Venturi nozzle-containing component, in addition to nor the gas control device is arranged is by means of a Bayonet catch on the above fan housing attached, d. H. the component is detachably formed by this, which its reason among other things is that the venturi nozzle made of plastic and the fan housing made of metal is formed.
Der Erfindung liegt die Aufgabe zugrunde, den Montageaufwand bei einer Mischeinrichtung der eingangs genannten Art zu reduzieren.Of the Invention is based on the object, the assembly costs at a To reduce mixing device of the type mentioned.
Diese Aufgabe ist mit einer Mischeinrichtung der eingangs genannten Art durch die im Kennzeichen des Patentanspruchs 1 aufgeführten Merkmale gelöst.These Task is with a mixing device of the type mentioned by the listed in the characterizing part of patent claim 1 Characteristics solved.
Nach der Erfindung ist also vorgesehen, dass mindestens ein schalenartiges Bauteil des Gehäuses und mindestens die Außenwandung der Gas-Luft-Mischstrecke als einstückiges Bauteil ausgebildet sind.To The invention is therefore intended that at least one shell-like Component of the housing and at least the outer wall the gas-air mixing path formed as a one-piece component are.
Mit anderen Worten ausgedrückt, wird erfindungsgemäß auf eine separate Ausbildung der Bauteile Gehäuseschale und Außenwandung der Gas-Luft-Mischstrecke, die vorzugsweise als Venturi-Düse ausgebildet ist, verzichtet. Dank dieser Maßgabe verringert sich der Montageaufwand (Arbeitszeit, Schrauben); ferner entfällt auch eine sonst erforderliche Dichtung zwischen Gehäuseschale und Außenwandung der Venturi-Düse, was weitere Kostenvorteile mit sich bringt.With In other words, according to the invention a separate design of the components housing shell and Outer wall of the gas-air mixing section, preferably is designed as a venturi nozzle omitted. thanks to this The assembly costs are reduced (working hours, Screws); it also eliminates any otherwise required Seal between housing shell and outer wall the Venturi nozzle, which brings further cost advantages.
Andere vorteilhafte Weiterbildungen der erfindungsgemäßen Mischeinrichtung ergeben sich aus den abhängigen Patentansprüchen.Other advantageous developments of the invention Mixing device result from the dependent claims.
Die erfindungsgemäße Mischeinrichtung einschließlich ihrer vorteilhaften Weiterbildungen gemäß der abhängigen Patentansprüche wird nachfolgend anhand der zeichnerischen Darstellung eines bevorzugten Ausführungsbeispiels näher erläutert.The including mixing device according to the invention their advantageous developments according to the dependent claims will be described below the graphic representation of a preferred embodiment explained in more detail.
