Definitions
- the invention relates to a stove, in particular an electric stove according to the preamble of Claim 1.
- a stove of this type is known from DE-C-35 16 847. It contains an oven muffle with a vapor extraction opening formed in a muffle wall, into which a catalyst is used. Downstream of the catalytic converter, part of the Muffle airflow mixed with cooling air, which from a space between the Muffle and a device housing sucked in and via an exhaust pipe to the outside is promoted, while the other part of the muffle air stream cleaned by the catalyst is returned to the oven muffle via a return line.
- the task is to be solved by the invention, an energy saving and a to achieve longer life of the catalyst material of the catalyst device.
- this task is performed by the characteristic features of Claim 1 solved.
- the invention relates to a stove, in particular an electric stove an oven muffle for cooking, baking and roasting; an air duct between the Oven muffle and an appliance housing; at least one fan for air circulation through the air duct and out into the outside atmosphere of the cooker; a Vapor exhaust opening, which contains a catalyst device, characterized in that that the flow path through the catalyst device is a catalyst heater and Has catalysis material, and that a return channel at one end to the Flow path at one between the catalyst heater and the catalyst material located point and with its other end connected to the oven muffle for returning part of the discharged from it through the vapor extraction opening Wrasens.
- a catalyst device characterized in that that the flow path through the catalyst device is a catalyst heater and Has catalysis material, and that a return channel at one end to the Flow path at one between the catalyst heater and the catalyst material located point and with its other end connected to the oven muffle for returning part of the discharged from it through the vapor extraction opening Wrasens.
- the invention results in energy savings since the oven muffle Air extracted from the vapor extraction opening (vapor) only through part of the Catalyst material or bypassing this only on the catalyst heater is passed and then without significant cooling in the oven muffle is returned. At the same time, a large part of the humidity, which is withdrawn from the oven muffle via the vapor extraction opening, back into it recycled. This prevents the oven muffle from drying out excessively cooked, baked or fried food (food to be cooked).
- the Return channel arranged a blower which conveys in the return direction.
- the stove shown in the drawing in particular an electric stove, has one Device housing 1, a housing cooling fan 2, an opening 3 in a catalyst cover 4 for reducing the pressure in the cooking space of an oven muffle 14 for cooking, baking and Roast meat; a catalyst heater 5; an air gap 6 between the catalytic material 7 and the radiator of the catalyst heater 5; an air return duct in the form of a Suction pipe 9, which with one end to the air gap 6 between the Catalyst material 7 and the radiator of the catalyst heater 5 is connected and is connected at its other end to an inlet opening 16 of the baking muffle 14; a blower 10 at the inlet opening 16 for extracting air from the air gap 6 between the catalyst material 7 and the radiator of the catalyst heater 5 and Returning this air into the cooking space 12 of the oven muffle 14; and a Hot air blower 11 in the cooking space 12 in order to circulate air therein.
- the fan 10 of the inlet opening 16 is through Fan wheel formed, which is fixed on the shaft of the hot air blower 11 rotatably.
- the blower 10 is one of those Hot air blower 11 separate and independently controllable blower.
- the cooling fan 2 sucks in the lower area of the cooker from the outside environment Cooling fresh air 20 in the space formed as a channel 18 between the oven muffle 14 and the appliance housing 1, so that this fresh air 20th below and behind and above the oven muffle 14 around this oven muffle 14 flows and in the upper range through at least one outlet 22 back into the open is blown.
- the cooling fan 2 sucks through the opening 3 of the catalyst cover 4 also exhaust air from the catalytic material 7 of the catalytic device 24.
- Electric heating elements 26 are shown schematically in the oven muffle 14.
- the catalytic material 7 is or preferably contains ceramic.
- the catalyst heater 5 contains at least one electric radiator.
