Definitions

  • the present invention relates to a cooking device which provides the effective utilization of the heaters that operate during the cooking process.
  • Cooking devices comprise one or more heaters that execute the cooking process by means of convection, and the food is cooked by the heat transfer created between the air heated by the heater and the foods to be cooked.
  • the temperature of the air in the cooking chamber is higher near the heater and lower in the distant parts. Therefore, the cooking process cannot be executed homogeneously.
  • a fan is positioned in the area of the heater, providing the air heated by the heater to be distributed throughout the cooking chamber homogeneously by means of the actuation of the fan and to increase the heat transfer from the heated air to the food to be cooked.
  • vanes that provide the air activated by the fan to be directed up to the side of the rear wall.
  • film heaters are positioned at the rear wall in the area of the air inlets and outlets. These heaters provide the heating of the sucked and blown air.
  • the object of the present invention is to design a cooking device in which the air is heated by the effective utilization of the heaters that are operated during the cooking process.
  • the cooking device designed to fulfill the objectives of the present invention, explicated in the first and the respective claims, comprises guides mounted on the rear wall such that they partially or completely contact the surface of the heater. Accordingly, the hot air flowing over the heater and activated by the fan can be delivered to the blowing holes to be blown into the cooking chamber without losing its retained heat energy. The temperature difference between the air activated in the vicinity of the heater and the air reaching the blowing holes is minimized, providing a homogeneous heat distribution and an economy in energy consumption.
  • Heaters may be fed by a single energy source or by separate energy sources. This provides for economizing the energy consumption by operating only the heater in the region where necessary.
  • the guides are positioned at the backside of the rear wall such that the air activated by the fan outflows from the blowing holes in nearly equal amounts and at nearly equal temperatures.
  • the guides having a structure that makes it easier for guiding the flow of the air, act like a channel through which air flows. Therefore, the air is heated as it is delivered to the blowing holes.
  • the channels formed on the rear wall are no longer necessary for the delivery of the fan activated air to the blowing holes.
  • the function of these channels is implemented more efficiently by the guides.
  • the present invention provides for the equal delivery of the air to the blowing holes on the rear wall with nearly the same temperature as the heat source and also provides the distribution of the hot air homogeneously in the cooking chamber by means of blowing the air having nearly the same temperature from all of the holes.

  • the cooking device (1) comprises an exterior cabin (2), a cooking chamber (3) positioned inside this exterior cabin (2) such that there is a gap in between them, one or more fans (6) for activating the air, situated between the cooking chamber (3) and the exterior cabin (2), one or more heaters (5) that provide heating the air, and a rear wall (4) that provides to direct the air activated by the fan, separating the cooking chamber
  • the rear wall (4) comprises one or more suction holes (7) on the section corresponding to the area swept by the fan (6), of various shapes and numbers, enabling the fan (6) to aspirate the air from the cooking chamber (3), and more than one blowing hole (8), situated between these suction holes (7) and the side walls of the cooking chamber (3), providing the heated and activated air to be delivered into the cooking chamber (3) ( Figure 1 and Figure 3).
  • the cooking device (1) comprises one or more guides (9) situated on the rear wall
  • the guide (9) is mounted on the surface of the heater (5) such that there is a partial or complete contact. All the guides (9) contacting the heater (5) act like a heat source. Consequently, the temperature difference between the air heated by the heater (5), activated by the fan (6) and the air reaching the blowing holes (8) is minimized.
  • the guides (9) are mounted above the heater (5) that is situated around the fan (6), such that they contact the heater (5).
  • the guide (9) is positioned in between the rear wall (4) and the exterior cabin (2) ( Figure 2, Figure 3, and Figure 8).
  • the heater (5) is mounted above the guide (9).
  • the guide (9) is mounted on the rear wall (4).
  • the heater (5) can either be embedded on the guide (9) or may surround the whole surface of the guide (9) ( Figure 4, Figure 5, Figure 6, Figure 7 and Figure 9).
  • the guides (9) are positioned on the periphery of the fan (6) with an angle suitable with the rotation direction of the fan (6) so as to provide the fan (6) to blow air in all directions ( Figure 8 and Figure 9).
  • the guides (9) are positioned around the fan (6), surrounding the periphery of the fan (6) in the radial direction and becoming horizontal while approaching the side walls of the cooking chamber (3) or the blowing holes (8), providing to direct the air flow ( Figure 2, Figure 3, and Figure 4).
  • the guides (9) are positioned oppositely above and below the fan (6).
  • the nearest surface of the guide (9) corresponding to the area swept by the fan (6) is curvilinear such that the air activated by the fan (6) can be suitably guided.
  • the surfaces which are the continuation of this curvilinear surface are linear ( Figure 5, and Figure 6).
  • the guides (9) are positioned around the fan (6) asymmetrically, with the fan (6) being in the middle, suitable to the rotation direction of the fan (6).
  • the guides (9) thus positioned adjust the air flow in the high pressure areas resulting from the rotation direction of the fan (6) ( Figure 7).
  • the guide (9) comprises protrusions
  • each heater (5) is fed by a separate energy source. Accordingly each heater (5) can be controlled separately and energy consumption can be economized by operating the heater (5) only in the area of necessity.
