Definitions

  • At least one heater and one fan are provided in ovens wherein the cooking process is performed by means of convection.
  • the casing of the cooking device is divided into two compartments by means of a fan covering plate.
  • the heater and the fan are disposed in the compartment which remains between the rear wall of the casing and the fan covering plate and the other compartment forms an oven cavity wherein foods to be cooked are placed.
  • the air heated by the heater is propelled by the fan and delivered into the oven cavity through the holes arranged on the fan covering plate and the food is provided to be cooked by means of heat transfer between the warm air and the food to be cooked.
  • the side walls comprising horizontal channels thereon are utilized in order to perform a homogeneous cooking. Heated air is received from the volume between the fan covering plate and the casing rear wall to the side walls by means of the fan. This air flows through the channel and is delivered to the oven cavity by means of the holes positioned so as to blow the air to the lower and upper surfaces of the tray.
  • the cooking device is stopped assuming that the same type of food in the other levels is also cooked and all the trays are taken from the cooking device simultaneously. In some cases this results in serving the food before it is fully cooked and hence in consumer dissatisfaction.
  • the aim of the present invention is the realization of a cooking device which provides a homogenous and effective cooking in all the levels of the oven cavity.
  • a fan covering plate that separates the section wherein the heater and the fan are located from the oven cavity, three passage gaps on each of the flanges situated on both sides of the fan covering plate and at least one side wall fastened to the side edge of the fan covering plate are disposed.
  • the area of the middle passage gap is greater than the area of the lower and upper passage gaps.
  • the area of the middle passage gap is smaller than the total area of the lower passage gap and the upper passage gap.
  • the area of the middle passage gap is one and half times the area of the lower passage gap or the upper passage gap.
  • At least one sucking opening, at least one blowing opening and at least one guidance member are provided on the fan covering plate.
  • the total area of the passage gaps is one and half times to three and half times, preferably two and half times the total area of the blowing openings.
  • the fan covering plate and the side walls are mounted angularly with respect to each other in the cooking device. This angle is between 30 and 60 degrees, preferably 45 degrees.
  • the flanges of the fan covering plate and the surface of the side walls facing the fan covering plate are produced with a suitable inclination.
  • the side wall comprises at least one channel having one inlet port providing the air coming from the passage gaps to enter therein and at least one hole arranged along the horizontal axis thereon providing the air received from the inlet port to be blown to the oven cavity, and at least one guide providing the trays to be disposed in the oven cavity to be positioned.
  • the air passing through the passage gaps is received into the channel by means of the air inlet port and while one part of this air flows in the channel, the other part is delivered to the oven cavity by means of the holes. Since equal amount of air passes through each passage gap by means of the different areas of the passage gaps, equal amount of air enters into the channels.
  • At least one separator is provided on the side wall, which extends along the gap between the inner surface of the side wall and the outer cabinet and prevents the air passage between the channels. Consequently, the equal amount of air received from the channel inlet ports is prevented from mixing with each other, and thus equal amount of air is provided in the channels during the cooking process.

Since there is air entrance into the oven cavity also through the blowing openings on the fan covering plate, the holes starts from a place close to the center of the channel and continues until the end of the channel on the side of the door. Thus, the portion of the foods facing the rear wall is prevented from being cooked more than the other portions.

  • a fan covering plate (6) dividing the inner volume into two is disposed in the area near the rear wall of the preferably rectangular-shaped outer cabinet (2).
  • the fan (5) and the heater (4) are located in the volume between the fan covering plate (6) and the outer cabinet (2).
  • the side walls (11) fastened to the fan covering plate (6) are disposed at both sides of the outer cabinet (2).
  • the volume remaining between the opposite side walls (11) and the fan covering plate (6) forms the oven cavity (3) together with the lower and upper surfaces of the outer cabinet (2) ( Figure 2).
  • the volume of the oven cavity (3) is generally greater than the volume wherein the fan (5) and the heater (4) are situated.
  • the air heated by the heater (4) and propelled by the fan (5) is directed to the front surface of the fan covering plate (6) and the flanges (17).
  • At least three passage gaps (10, 110, 210), which provide the air to be directed to the side wall (11), are disposed on each flange (17).
  • the area of the middle passage gap (10) is greater than the areas of the passage gaps (110, 210) located therebelow and thereabove. Since the center point of the fan (5) and the center point of the fan covering plate (6) almost overlap, the flow rate of the air passing through the middle passage gap (10) located at the same horizontal level with the preferably axial type fan (5) is less than the flow rate of the air passing through the lower and upper passage gaps (110, 210). Accordingly, the areas of the lower and upper passage gaps (110, 210) are selected to be smaller than the middle passage gap (10) in inverse proportion with the flow rate of the air passing through the lower and upper passage gaps (110, 210). Thus, almost same amount of air passes through all the passage gaps (10, 110, 210) and a homogenous heat distribution is provided in the cooking device (1) in the vertical axis.

  • guidance members (9) extending from the inner surface of the fan covering plate (6) to the outer cabinet (2) are disposed on the fan covering plate (6) ( Figure 7, Figure 8).
  • the guidance members (9) are disposed in various geometry and sizes in different sections of the fan covering plate (6) depending on the angle and speed of the air coming from the fan (5).
  • the amount of the air leaving the blowing openings (8) by impacting the guidance members (9) is increased. Consequently, a homogenous and effective air distribution is attained in the front side of the oven cavity (3).
  • some amount of the air is directed to the passage gaps (10, 110, 210) on the flange (17) and passes from here to the side wall (11).
  • the total area of the passage gaps (10, 110, 210) is one and half times to three and half times the total area of the blowing openings (8). In the preferred embodiment of the present invention, the total area of the passage gaps (10, 110, 210) is two and half times the total area of the blowing openings (8). Since the air received to the side wall (11) flows along the entire side wall (11) in the horizontal axis, it is subjected to various losses. By means of the selected ratio, equal amounts of air are provided to be blown from the fan covering plate (6) and the side walls (11) and thus the foods in the tray are provided to be cooked more homogeneously.
