Definitions
- the present invention relates to an oven with a baking space with a baking space opening, which can be closed by a door, and with a cooling fan that one Cooling air flow from a discharge opening in the front of the oven above the Presses the baking chamber opening into the open.
- Such an oven is known from the publication DE 37 41 975 A1, the Cooking appliance is also operated with steam. Towards the end of the cooking phase, over a controllable steam outlet in the ceiling area of the oven muffle from the Cooking space steam is discharged to the suction side of a fan and at the same time via a controllable air supply opening from the pressure channel of the blower air to the cooking space fed.
- the steam in the cooking chamber is so far dismantled so that no disturbing steam escapes when the oven door is opened. Especially is prevented that one in this area when opening the door Operator or steam flows into the face. This is particularly disadvantageous the exchange of hot muffle air with cooling air and the associated Reduce the oven temperature before opening the oven door.
- the object of the present invention is in an oven according to the preamble of claim 1 with simple means when opening the door an inflow of Prevent operator from hot air.
- the design is particularly simple and can be optimally adjusted to the respective oven structure it is when the flow guide is movably held on the oven, and when opening the door from a rest position to one that deflects the cooling flow downwards Operating position is adjustable. In terms of assembly technology, it is cheap if that Cooling fan for blowing out the cooling air flow from the oven a blow-out shaft is assigned in which the flow guide is held. Furthermore, through this Measure the flow guide held in the oven without its front Affect appearance. In addition, the function of the air directing means can already installation of the exhaust duct in the oven.
- the oven has a door opening switch, which when opening the door an actuator controls that the flow guide moves into the operating position.
- the flow guide could also be biased into the operating position be, and the movement of the flow guide in the operating position by the Opening the door can be released.
- the air guiding means is immovable in the area the discharge opening arranged. It directs the cooling air flow down and When the door is closed, pushes it into an open front located in the door Air duct. When the door is open, the downward directs out of the blow-out opening flowing cooling air flow away the hot rising vapor flow down.
- the cooling fan advantageously switches up to a higher output whenever if the door is opened when the baking chamber is hot. Safe protection for the operator when the door is opened, this also ensures that the normal fan output, which is sufficient to cool the oven, is not sufficient here would be great.
- Fig. 1 an oven 1 is shown according to the state of the art.
- an oven muffle 5 whose The loading opening can be closed at the front by an oven door 7.
- Above the oven door 7 is on the housing 3 a front panel 9 with known Controls 11 and display elements 13 attached.
- a suction fan 15 This sucks Intake openings 17 of the housing 3 and if necessary through a vapor opening 19 in the Ceiling area of the oven muffle 5 cooling air or vapors.
- the suction fan 15 presses the sucked-in air-vapor mixture into one between the suction fan 15 and the front of the oven 1 extending exhaust duct 21.
- Der Blow-out duct 21 has essentially the entire width of the front Oven 1 blow-out openings 23 through which the mixture is transported outdoors (Fig. 1).
- the oven 1 has above the Muffle 5 on the blow-out shaft 21 in a modified form.
- On one essentially horizontally extending section of the blow-out duct 21 closes a duct arch 41, in which the cooling air flow is guided downwards.
- the duct bend 41 opens out into a likewise curved end extending air duct 43 which is arranged in the oven door 7.
- opening the Door becomes the air duct 43 of the oven door 7 from the area of the duct arch 41 of the blow-out duct 21 is drawn. That is why the blown out streams Cooling air through one arranged in this area over essentially the entire width Air baffle 45 guided, according to the first embodiment ascending vapor flow downwards.
