Definitions

  • the present invention relates to an electric cooking oven, and in particular a cooking oven comprising a reflective screen adapted to reflect the radiation of a heating element towards the inside of the oven.
  • an element heating element such as an electrical resistance is generally arranged in a top of the oven enclosure so as to radiate above the food to cook.
  • a reflector screen is then attached to the upper wall of the furnace enclosure to allow to reflect the radiation of the resistance electric on the cooking dishes.
  • This reflective screen thus acts as a source of energy for direct the infrared radiation of the heating element towards the inside of the cooking chamber.
  • the object of the present invention is to provide a baking oven electric with better energy efficiency.
  • the screen of the heating element has no connection with the cooking chamber.
  • This screen layout on the heating element allows overall to reduce the electric consumption of the baking oven electric.
  • the present invention relates to an electric cooking oven such as previously described.
  • an upper wall of the cooking chamber includes a fume extraction port, the exhaust port being extended towards the interior of the cooking chamber by a conduit discharge having an end opening under the heating element.
  • the air and fumes to be evacuated are not taken over the heating element, but below it.
  • the evacuation orifice is also arranged in the upper wall of the cooking chamber, the hottest air is primarily evacuated.
  • this hot air can be kept to a maximum in the enclosure and save energy for maintaining the temperature in the enclosure Cooking.
  • the screen extends next to the entire heating element and the screen has a opening disposed substantially opposite the discharge port.
  • the screen can reflect the radiation emitted by the element heating at any point of the latter.
  • the oven of cooking comprises a peripheral day between the screen and the cooking chamber.
  • This electric cooking oven 1 comprises an enclosure of cooking 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 bodywork of the furnace 1 which conventionally surrounds this enclosure of cooking 2.
  • a heating element 4 Inside this cooking chamber 2, is arranged a heating element 4.
  • a screen 5 is disposed above this resistance 4 so as to reflect the infrared radiation emitted by this electrical resistance.
  • This screen 5 makes it possible to send back the radiation of the resistor 4 inward of the cooking chamber 2, towards the food to be cooked.
  • this screen 5 is fixed only on the heating element 4.
  • this screen 5 may comprise snap clips 6.
  • the screen 5 covers the resistance 4 so as to reflect the entirety of 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 7 which allows the exit of cooking fumes from the enclosure of cooking 2.
  • the screen 5 comprises also an opening 8 which is disposed substantially at the right of the exhaust port 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 down the exit of the fumes from cooking out of the enclosure.
  • a day device 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 fumes would then be slowed, which would allow an energy saving of around 70 W / h.
  • the screen 5 is formed of 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 further improves the cleaning of the glass door 3 of 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 reduce the temperature at which is worn the enamel coating of the upper wall 2a above the electrical resistance 4.
  • FIG. 3 an oven according to FIG. the invention.
  • a heating element formed of an electrical resistance 4 similar to that previously described.
  • the screen 5 is also fixed directly on this resistance 4 and the electrical resistance 4 and the screen 5 are arranged in parallel to an upper wall 2a of the cooking chamber 2.
  • the upper wall 2 has an orifice evacuation 7.
  • the discharge orifice 7 is extended towards inside the cooking chamber 2 by an evacuation duct 11.
  • This exhaust duct comprises a free end 11a which opens under the heating element 4.
  • This exhaust duct 11 makes it possible to evacuate the air from the enclosure of cooking 2 by sucking the air under the heating element 4.
  • This end 11a of the evacuation 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 evacuation duct 11 extending the evacuation orifice It could also be used without the screen reflector.
  • the screen 5 may not include an opening 8 or perforated grid 9, the evacuation of gas being carried out only by the day device 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 at the front door 3 of the oven.
