Definitions

  • the present invention relates to an oven comprising a fan and ventilating duct providing the electronic elements to be cooled.
  • the electronic elements situated in the control panel are cooled by means of a cooling fan and a ventilating duct disposed at the upper side of the casing enclosing the cooking chamber.
  • the cooling fan furthermore speeds up the discharge to the outside of the hot and humid air passing from the chimney to the cooling duct in the cooking process. If the cooling fan operates more than necessary for keeping the electronic elements within the desired temperature limits, the heat in the cooking chamber is discharged outside and energy consumption increases. If the cooling fan operates less, then the electronic elements cannot be cooled as required and moreover the cooking time is prolonged and cooking quality decreases since sufficient amount of humidity cannot be aspirated from the cooking chamber.

  • the oven realized in order to attain the aim of the present invention and explicated in the first claim and the respective claims thereof, comprises a ventilating duct disposed at the space at the upper side of the cooking chamber and provides the discharge of air sucked from the inside of the oven by the fan to the outside surrounding and an exhaust device that extends from the cooking chamber to the inside of the ventilating duct in the vertical direction and opens to the space inside the oven from above the ventilating duct and a cap closed on the exhaust device and that prevents the exhaust device from aspirating excess amount of humid and hot air from the cooking chamber by the air curtain effect created therein.
  • Air passage holes are disposed on the ventilating duct between the
  • the hot and humid air in the cooking chamber is prevented from being excessively discharged to the outside by the cap when the fan is in the operating mode.
  • the fan does not operate when vapor needs to be discharged to the outside from the cooking chamber.
  • the oven comprises a heat sensor disposed in the vicinity of the control unit and the control unit that activates the fan in case the temperature of the electronic elements exceeds a limit value.
  • the fan is operated only when the electronic elements in the control unit need to be cooled and as long as the fan operates, the hot and humid air in the cooking chamber is prevented from being discharged to the outside by means of the air curtain created in the cap.
  • the oven comprises a humidity sensor disposed in the cooking chamber and the control unit that deactivates the fan when the amount of humidity in the cooking chamber exceeds a limit value.
  • the vapor in the cooking chamber is discharged to the outside by natural convection.
  • the width size of the cap is greater than the width size of the exhaust device.
  • the cap is cup-shaped.
  • the cap is shaped as square or rectangular prism with one surface open.
  • the electronic elements in the control unit are provided to be effectively cooled and energy saving is provided by preventing excessive amount of hot air to be discharged to the outside from the inside of the cooking chamber with the air curtain effect created by the cap disposed on the exhaust device.

  • Figure 1 - is the schematic view of an oven.
  • Figure 2 - is the cross sectional view of a cap.
  • Figure 3 - is the schematic view of air flow in the ventilating duct and the exhaust device of an oven while the fan operates.

  • the oven (1 ) of the present invention comprises:
  • a cap (15) which is disposed at the upper side of the exhaust device (1 1 ), shaped like an open bottom box, which has an upper wall (12) covering the upper side thereof and a side wall (13) seated on the ventilating duct (9), that surrounds the periphery of the exhaust device (1 1) by extending downwards from the upper wall (12) in the vertical direction and a cavity (14) enclosed by the upper wall (12) and the side wall (13) and which prevents excess amount of humid and hot air to be discharged from the cooking chamber (3) by creating the air curtain effect in the cavity (14) when the fan (10) operates.
  • the oven (1 ) furthermore comprises one or more air passage holes (16) opening over the ventilating duct (9), disposed between the exhaust device (1 1 ) and the side wall (13) surrounding it and allowing air to pass from the ventilating duct (9) to the cavity (14) or from the cavity (14) to the ventilating duct (9).

  • the air entering into the cavity (14) prevents the exhaust device (1 1 ) from sucking air from the cooking chamber (3) by creating air curtain effect over the exhaust device (1 1 ) ( Figure 3). Consequently, while the electronic elements in the control unit (6) are cooled effectively by the fan (10), heat loss is decreased and energy saving is provided at the same time by preventing excessive amount of hot air exiting from the cooking chamber (3) by means of the cap (15).
  • the fan (10) does not operate when vapor needs to be discharged to the outside from the cooking chamber (3).
  • the vapor leaving the cooking chamber (3) fills into the cavity (14) inside the cap (15) by means of the exhaust device (1 1 ) and passes into the ventilating duct (9) through the air passage hole (16) since an air curtain effect is not encountered here and is discharged to the outside surrounding from here by means of the outlet opening (8) ( Figure 4).
