Definitions

the invention relates to an oven according to the preamble of claim 1.
Ovens with a device for pyrolytic self-cleaning are known in particular (DE-AS 25 45 531; DE 23 43 640 A1), in which, with a free air gap to a front door glass plate with a transparent inner area, one of several likewise transparent, but the Passage of heat radiation-inhibiting glass plates or glass plate composite existing window assembly is arranged within the metallic door floor, wherein in the cavity between the window assembly and the front glass plate through an upper and lower air openings an air convection flow is used to dissipate heat within the oven door.
a screen which can be moved from outside the viewing area to the viewing area is provided for the pyrolytic self-cleaning operation, through which the air flow is guided during self-cleaning operation and which is also intended to prevent heat radiation to the outside.
Esp. Due to the thermally insulating multiple glazing within the window assembly, the see-through area remains relatively cool for a long time, while the other door areas, for example the door edge area, heat up relatively quickly. It is usually impossible to prevent vapors or steam coming from the interior of the furnace muffle from entering the interior of the furnace door, for example at the edge of the door assembly, and condensing at the coldest point, i.e. in the viewing area, for example on the inner surface of the glass pane on the front.
the invention has for its object to improve an oven of the type mentioned in the preamble of claim 1 so that condensation in the viewing area of the oven door can be at least largely avoided.
the convection flow at least to a large extent kept away from the viewing area by the flow barrier is discharged to the outside through air outlet openings at the upper area, these air outlet openings being located in the immediate vicinity of cooling air ventilation slots, as a result of which the cooling air flow forced by a cooling air blower is discharged due to the so-called injector effect, the convection flow taking place inside the oven door is increasingly withdrawn from the door area.
an oven muffle 3 surrounded by thermal insulation 2 is arranged within an oven housing 1, the heating elements of which are not shown.
an electrical control device 4 there is a cooling air blower 5 for discharging the heated air located in the housing space between the furnace muffle 3 and furnace housing 1, the pressure side of which is connected to an exhaust air duct 6, which in turn for example extends over a large part of the oven width
Extending ventilation slot 7 opens on the front of the oven below the control device, through which the heated exhaust air is discharged to the outside (see arrow direction).
the furnace muffle 3 which is open on one side, can be closed by a furnace door 8, which is essentially formed from a large glass pane 9 on the front side, which has a pane region that is, for example, rectangular, transparent and a viewing window 10 in the central area, while the glass pane 9 is not transparent outside of this viewing window , for example with a print.
This glass pane 9 is supported by a metallic door floor 11, formed by two step-shaped sections 11.1 and 11.2 (see FIG. 2 in this regard).
a seal 16 for example a glass silk seal, which is required instead of a rubber seal when the oven is pyrolytically self-cleaning.
a seal 16 for example a glass silk seal, which is required instead of a rubber seal when the oven is pyrolytically self-cleaning.
vapors or steam get into the interior of the door assembly when the oven is in operation, it being possible to assume that the glass pane assembly 13/14 is steam-tight. This steam passes below and above the viewing window 10 into the cavities 17 of the door base 11 (see arrows in Fig. 2).
a frame-like, for example metallic flow barrier 18 is attached to the outer boundary of the composite frame 13 and extends at least approximately to the inner surface of the front glass pane 9, preferably being supported on this inner surface in the peripheral region of the viewing window 10.
This flow barrier 18 is formed by frame-like air baffles, which in the exemplary embodiment are funnel-like inclined outwards.
