Abstract

In a baking oven with an oven muffle which can be closed by a door, the oven muffle being equipped with devices for upper and lower heat, there is fastened on the outside to a floor-side baking oven housing wall (1) a sheet-metal housing (2) which serves to accommodate a heating element for lower heat (3), the heating element for lower heat (3), as a result of the constructional design of the sheet-metal housing (2), being accurately mounted and arranged at a defined distance from the baking oven housing wall (1). <IMAGE>

Description

Die Neuerung bezieht sich auf einen Backofen mit einer durch eine Tür verschließbaren Ofenmuffel, wobei die Ofenmuffel mit Einrichtungen für Ober- und Unterhitze ausgestattet ist. Die allgemein übliche Art, Unterhitzeheizkörper anzuordnen, besteht in einer Zwischenblechtechnik An der bodenseitigen Backofengehäusewand wird das Zwischenblech durch seitlich am Backofen angeschweißte Stützbleche angedrückt. Der Unterhitzeheizkörper wird durch geeignete konstruktive Maßnahmen auf das Zwischenblech geschoben. Durch diese Anordnung des Unterhitzeheizkörpers ist eine einteilige Backofenisolation nicht realisierbar und aus Isolationsgründen ein Austausch der Heizung problematisch.The innovation relates to an oven with an oven muffle that can be closed by a door, the oven muffle being equipped with devices for top and bottom heat. The generally customary way of arranging bottom heat radiators consists of an intermediate plate technology. The intermediate plate is pressed onto the bottom-side oven housing wall by support plates welded onto the side of the oven. The bottom heat radiator is pushed onto the intermediate plate by suitable design measures. Due to this arrangement of the bottom heat radiator, one-piece oven insulation is not feasible and replacement of the heating is problematic for insulation reasons.

Die Aufgabe der Neuerung besteht darin, eine solche Anordnung für die Unterhitzeheizkörper zu entwickeln, daß der Unterhitzeheizkörper lagegenau und in definiertem Abstand zum Muffelboden positionierbar ist, wobei ein leichtes Austauschen des Unterterhitzeheizkörpers möglich sein muß und eine einteilige Backofenmantelisolation erfolgen kann.The object of the innovation is to develop such an arrangement for the lower heat radiator that the lower heat radiator can be positioned precisely and at a defined distance from the muffle bottom, with an easy replacement of the lower heat radiator must be possible and a one-piece oven jacket insulation can take place.

Die neuerungsgemäße Anordnung zur Lösung dieser Aufgabe ist dadurch gekennzeichnet, daß an einer bodenseitigen Backofengehäusewand außenseitig eine zur Aufnahme einer Heizung für Unterhitze dienende Blechtasche befestigt ist, wobei die Heizung für die Unterhitze infolge der konstruktiven Ausbildung der Blechtasche exakt gelagert und im definierten Abstand zum Backofenboden angeordnet ist. Eine vorteilhafte Ausgestaltung der Neuerung besteht darin, daß die Heizung für Unterhitze Befestigungsstege besitzt, die in Bodenprägungen der Blechtasche geführt werden und in Noppen einrasten. Weitere vorteilhafte Ausgestaltungen der Neuerung sind in den Unteransprüchen enthalten. Ein Ausführungsbeispiel nach der Neuerung ist im folgenden anhand der Zeichnung näher beschrieben. Es zeigt

The inventive arrangement for solving this problem is characterized in that a sheet metal pocket serving to accommodate a heater for bottom heat is attached to the outside of a bottom oven housing wall, the heater for the bottom heat being mounted precisely due to the constructive design of the tin pocket and arranged at a defined distance from the oven floor is. An advantageous embodiment of the innovation is that the heater for bottom heat has fastening webs which are guided in the embossed base of the tin pocket and snap into knobs. Further advantageous refinements of the innovation are contained in the subclaims. An embodiment according to the innovation is described below with reference to the drawing. It shows

a partial view of the heater for bottom heat,
Fig. 1b
another partial view of the heater for bottom heat,
Fig. 2
a tin pocket attached to the oven housing wall with inserted heater for bottom heat.

Gemäß Fig. 2 ist an einer Backofengehäusewand 1 eine Blechtasche 2 befestigt, die vorzugsweise an die Gehäusewand 1 angeschweißt wird. Eine Heizung für Unterhitze 3 wird in die Blechtasche eingeschoben und ist dadurch lagegenau und in definiertem Abstand zum Muffelboden angeordnet. Die Blechtasche 2 ist so konstruiert, daß die Heizung für Unterhitze 3 leicht einschiebbar ist. Durch einschubseitige und endseitige Bodenprägungen der Blechtasche 2, die in schiefen Ebenen liegen, sowie durch endseitig angeordnete Noppen 4, gelingt es, die Unterhitzeheizkörper 3 lagegenau einzurasten. Diesbezüglich besitzt die Heizung für Unterhitze 3 Befestigungsstege 5, 6, die einerseits die Heizkörpergeometrie stabilisieren und andererseits ein Einrasten gestatten. Die Abmessungen der Blechtasche 2 garantieren exakte Lagegenauigkeit und definierten Abstand der Heizung zum Backofenboden. Durch die Blechtasche 2 wird eine einteilige Backofenmantelisolation ausführbar, wobei der kundendiensttechnische Austausch der Heizung für Unterhitze 3 nicht beeinträchtigt wird. Eine andere Art der Befestigung der Blechtasche 2 an der Backofengehäusewand 1 wäre durch Verschrauben, Vernieten oder Kleben denkbar, jedoch ungünstiger als die vorgeschlagene Verschweißung zwischen der Backofengehäusewand 1 und der Blechtasche 2.2, a sheet metal pocket 2 is fastened to an oven housing wall 1, which is preferably welded to the housing wall 1. A heater for bottom heat 3 is inserted into the tin pocket and is therefore positioned precisely and at a defined distance from the muffle bottom. The tin pocket 2 is designed so that the heater for bottom heat 3 is easily inserted. By inserting and embossing the bottom of the sheet metal pocket 2, which lie in inclined planes, as well as by knobs 4 arranged at the end, the bottom heat radiator 3 can be snapped into position. In this regard, the heater for bottom heat has 3 mounting webs 5, 6, which on the one hand stabilize the radiator geometry and on the other hand allow it to snap into place. The dimensions of the sheet metal pocket 2 guarantee exact positional accuracy and defined distance between the heater and the oven floor. One-piece oven jacket insulation can be carried out through the sheet metal pocket 2, the customer service exchange of the heating for the bottom heat 3 not being impaired. Another type of fastening of the sheet metal pocket 2 to the oven housing wall 1 would be conceivable by screwing, riveting or gluing, but less favorable than the proposed welding between the oven housing wall 1 and the sheet metal pocket 2.
