Definitions

the present invention relates to an electric cooking oven, and in particular a baking oven comprising a reflective screen adapted to reflect the radiation of a heating element towards the interior of the oven.
one element heater such that an electrical resistance is generally arranged in a upper part of the oven enclosure so as to radiate above the food to be cooked.
a screen forming a reflector is then fixed to the upper wall of the oven enclosure to reflect the radiation of the resistance electric on the dishes to be cooked.
This reflective screen thus acts as a source of energy for direct the infrared radiation from the heating element towards the interior of the cooking chamber.
the object of the present invention is to provide a cooking oven electric with better energy efficiency.
the electric cooking oven targeted by the invention includes a cooking chamber, a heating element and a screen suitable for reflect the radiation of the heating element towards the interior of the enclosure cooking.
the screen is fixed only on the heating element.
the screen of the heating element has no connection with the cooking chamber.
This arrangement of the screen on the heating element allows overall to reduce the electric consumption of the baking oven electric.
the screen extends next to the entire heating element.
the screen can thus reflect the radiation emitted by the element heating at any point of the latter.
the cooking has a peripheral day between the screen and the cooking chamber.
a upper wall of the cooking chamber includes an outlet for cooking fumes and the screen has an opening arranged substantially in look at the discharge opening.
This exhaust orifice makes it possible to favor the exit of the fumes cooking through the oven exhaust port.
the orifice outlet is extended towards the inside of the cooking chamber by a duct outlet having an end opening under the heating element.
the air and the fumes to be evacuated are not taken above the heating element, but below it.
the hottest air in a cooking chamber is at the top of it.
the warmest air is primarily evacuated.
This electric cooking oven 1 comprises an enclosure of firing 2, commonly called muffle, and closed on a front face by a door 3.
FIG. 1 only the cooking chamber 2 is shown, without the body of the oven 1 which conventionally surrounds this enclosure of cooking 2.
a heating element 4 Inside this cooking enclosure 2, is arranged a heating element 4.
a screen 5 is arranged above this resistance. electric 4 so as to reflect the infrared radiation emitted by this electrical resistance.
This screen 5 makes it possible to return the radiation of the resistance 4 towards the inside of the cooking chamber 2, towards the food to be cooked.
this screen 5 is fixed only on the element heating 4.
this screen 5 may include snap clips 6.
screen 5 covers the resistance electric 4 so as to reflect all the infrared radiation emitted by this resistance 4.
the screen 5 thus also extends in a plane parallel to the wall upper 2a of the cooking chamber.
This upper wall 2a further comprises an orifice exhaust 7 which allows the exit of cooking fumes from the enclosure of cooking 2.
screen 5 includes also an opening 8 which happens to be disposed substantially at the right of the discharge opening 7.
this opening 8 is here closed by a perforated grid 9 having multiple orifices for the passage of air.
This perforated grid 9 makes it possible to slow the exit of the smoke from cooking outside the oven.
peripheral 10 disposed between the periphery of the screen 5 and the cooking chamber 2.
This peripheral day 10 thus forms a slot extending all around the screen 5.
the evacuation of smoke would be slowed down, which would allow an energy saving of around 70 W / h.
the screen 5 is formed from a stainless steel plate having a low emissivity, less than 0.5.
the emissivity of the screen must be less than that of the enclosure.
the screen 5 also improves the cleaning of the glass of the door 3 by the cooking chamber 2, thanks to the reflection of the infrared radiation in direction of the oven door.
this screen 5 makes it possible to decrease the temperature to which is worn the enamel coating of the upper wall 2a above electrical resistance 4.
a heating element formed by an electrical resistance 4 similar to that previously described.
the screen 5 is also fixed directly to this resistor electrical 4 and electrical resistance 4 and screen 5 are arranged in parallel to an upper wall 2a of the cooking chamber 2.
the upper wall 2a has an orifice Evacuation 7.
the discharge orifice 7 is extended towards the interior of the cooking chamber 2 by an exhaust duct 11.
This discharge conduit includes a free end 11a which opens out under the heating element 4.
This exhaust duct 11 makes it possible to evacuate the air from the enclosure of cooking 2 by sucking in the air located under the heating element 4.
This end 11a of the discharge duct 11 is preferably also closed by a perforated grid 12.
the screen 5 has an opening 13 allowing the passage of this exhaust duct 11 beyond the screen 5 and the element heating 4.
the discharge conduit 11 extending the discharge orifice 7 could also be used without the presence of the screen 5 forming reflector.
the screen 5 may not include an opening 8 or perforated grid 9, the gas being evacuated only by day peripheral 10 located between this screen 5 and the cooking chamber 2.
the heating element 4 and the screen 5 can be arranged differently inside the cooking chamber 2, and in particular be arranged parallel to a rear wall of the cooking chamber, facing to the front door 3 of the oven.
