Definitions

  • the present invention relates to an oven, the ventilating effectiveness of which is increased.
  • the oven cavity is separated into more than one volume by means of aseparator for the aim of cooking different foodstuffs at the same time.
  • one of the separated volumes is heated instead of heating the entire oven cavity for cooking a small amount of food, thus providing energy saving.
  • the hot and humid air generated during cooking is sucked from inside the oven cavity and discharged from the oven.
  • the hot and humid air generated at the top compartment is discharged outside with the present ventilation means of the oven.
  • the hot and humid air generated at the bottom compartment results in condensation in the top compartment and also in decrease of cooking quality at the bottom compartment since the said air cannot be discharged outside directly.
  • Japanese Patent Document No. JP58193031 an oven is described, that comprises a separator placed into the cooking chamber and which divides the cooking volume into two. With the separator being placed into the cooking chamber, the front of the intermediate blowing hole, between the main suction hole and the blowing hole, is opened.
  • the aim of the present invention is the realization of an oven wherein ventilation effectiveness is increased in the separated oven cavity volumes when the separator is placed into the oven cavity.
  • the oven realized in order to attain the aim of the present invention comprises an exterior body, a casing positioned in the exterior body such that a gap remains therebetween, an oven cavity situated inside the casing and wherein the cooking process is performed, a rear wall situated in the oven cavity, at least one fan disposed between the exterior body and the casing that propels the air, at least one separator that can be attached to/detached from the oven cavity, dividing the oven cavity into more than one volume and at least two compartments inside the oven cavity, one situated at the top, the other at the bottom, and separated from each other by the separator.
  • the air sucked from the outside environment is circulated around the casing and delivered to the outside environment.
  • an air line is formed that circulates between the body and the casing.
  • the oven of the present invention comprises a discharge line, one end connected inside the bottom compartment, the other end to the volume between the casing and the exterior body.
  • the oven volume is divided into more than one volume by means of the separator in order that the odors do not mix with each other while cooking the foods or that the foods are cooked under different conditions.
  • the water vapor collected in the bottom compartment passes through the discharge line and is thus directly delivered between the casing and the exterior body.
  • the water vapor passing to between the casing and the exterior body is discharged outside with the air line.
  • the oven of the present invention comprises at least one valve situated at the front of the discharge line end connected to the oven cavity and at least one opening-closing mechanism that, by moving the valve, provides the front of the discharge line end connected to the oven cavity to be opened when the separator is placed into the oven cavity and provides the front of the discharge line end connected to the oven cavity to be closed when the separator is taken outside the oven cavity.
  • the hot and humid air generated inside the bottom compartment passes through the discharge line.
  • the hot and humid air passing to between the casing and the body reaches the air line directed by the fan and is discharged out of the oven. Thus, formation of condensation inside the oven cavity is prevented.
  • the rear wall comprises more than one hole arranged at the front of the discharge line end opening into the oven cavity.
  • the valve moves by getting away from the front of the holes when the separator approaches the rear wall.
  • air is provided to pass from the holes to the discharge line.
  • the hot and humid air contained inside the compartment is delivered to the discharge line by passing through the holes.
  • the air sucking direction can be changed by means of the holes and the valve.
  • the discharge line is almost shaped as a bend.
  • the air contained in the discharge line is provided to be directed effectively.
  • the discharge line has a shape that enables the humid air leaving therefrom to merge with the air circulating between the exterior body and the casing.
  • the water vapor generated inside the bottom compartment during cooking is directly discharged outside with the air line by passing through the discharge line.
  • the end of the discharge line remaining between the exterior body and the casing is in truncated shape.
  • almost all of the air passing through the discharge line is provided to leave the discharge line in the same direction and to be directed towards the air line.
  • the opening-closing mechanism comprises a pusher against which the separator bears when placed into the oven cavity and at least one shaft that moves the valve by rotating around its axis when actuated by the pusher.
  • the separator actuates the pusher and moves the pusher while being placed into the oven cavity.
  • the shaft, connected to the pusher rotates as well, and provides the valve to be moved by rotating. Thus, the front of the end of the discharge line connected to the oven cavity is opened.
  • the opening-closing mechanism comprises at least one gear rack against which the pusher bears and at least one pinion that bear against the gear rack and moves the shaft.
  • the separator actuates the pusher and moves the pusher while being placed into the oven cavity.

  • the valve moves away from the front of the discharge line end opening into the bottom compartment.
  • the front of the discharge line end opening into the bottom compartment is opened and thus air from the bottom compartment is provided to pass into the discharge line.
  • the opening-closing mechanism comprises a resilient member that provides the pusher to resume its initial position when the separator is taken out of the oven cavity.
  • the resilient member is compressed while the separator is being placed into the oven cavity.
  • the compressed resilient member stretches while the separator is removed from the oven cavity and provides the valve to be moved.
  • the opening-closing mechanism comprises at least one resilient member against which the gear rack bears.
  • the resilient member As the gear rack moves, the resilient member is compressed between the gear rack and the body wall.
  • the gear rack and the pusher are released and thus the compression force exerted on the resilient member is removed.
  • the resilient member stretches and provides the valve to be moved.
  • the resilient member is spring-shaped.
  • the shaft extends in the vertical plane.
  • the shaft is situated on the diameter of the valve in the vertical axis. As the shaft moves, the valve also moves by rotating.
  • an oven is realized wherein the formation of condensation in one compartment due to increase of temperature in the other compartment is prevented and the ventilation effectiveness is increased while performing cooking in different compartments.
