Definitions

  • the present invention relates to an oven wherein the dirt on the oven base can be cleaned in household ovens with air impingement jet technology.
  • the air impingement jet technology is used in ovens for various cooking applications.
  • high-speed jets of hot air impinge a foodstuff vertically and/or impinge cooking members or trays carrying foodstuffs.
  • Hot air jets are delivered by means of nozzles. Said nozzles are generally placed on the upper and lower walls of the oven so as to be perpendicular to the foodstuff.
  • high-speed jets of hot air impinge the foodstuff, thus providing more homogeneous heat distribution rates or shorter cooking times.
  • the aim of the present invention is the realization of an oven comprising an air impingement jet technology which eliminates the problem of the liquids, which spill from the foodstuffs while said foodstuffs are being loaded into/unloaded from the oven, being burnt or getting stuck on the oven bottom due to high temperatures, thus providing ease of cleaning.
  • Another aim of the present invention is the realization of an oven comprising an air impingement jet technology which eliminates the problem of the speed of the air, delivered by the nozzles close to the front wall of the oven, being low and hence the problem of nonhomogeneous cooking on the foodstuff surface.
  • Another aim of the present invention is the realization of an oven comprising an air impingement jet technology which eliminates the problem, encountered in the state of the art, of the air losing speed while flowing from the rear side of the oven towards the front side thereof, which increase the flow speed of air towards the front side of the oven and which prevents the loss in speed and heat at the front wall region of the oven.
  • Another aim of the present invention is the realization of an oven comprising an air impingement jet technology which eliminates the problem of the airtightness of the plates, whereon the nozzles are provided, being deteriorated due to the frequent detachment of the plates.
  • the oven realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises an oven compartment which is defined by side walls, a rear wall, an upper wall, a lower wall and a front wall and wherein the foodstuffs to be cooked are placed by means of a cooking member; a lower plate which is provided on the lower wall; and a plurality of jet nozzles which are arranged in successive rows and columns on said lower plate.
  • Said oven comprises a plurality of slits which are positioned between said jet nozzles and a hidden tray which is positioned under the lower plate and which collects liquids that may flow through said slits.
  • the oven comprises the slits which are positioned in a disordered manner in various places on the lower plate.
  • the oven comprises the slits which are arranged as successive rows and columns on the lower plate so as to cover the entire surface.
  • the oven comprises the slits which are arranged as successive rows and columns among the jet nozzles in an area corresponding to the center region of the lower plate.
  • the oven comprises the slits which are configured so as to have different or same dimensions.
  • the oven comprises a gap which is provided between the hidden tray and the lower plate and through which the hot air passes.
  • the oven comprises a hidden tray the height of which, depending on the arrangement thereof, decreases from the rear wall towards the front wall.
  • the oven comprises a hidden tray wherein the ratio of the front height thereof to the rear height thereof is between 0.3 and 0.8.
  • the oven comprises a fan sheet metal which is mounted to the rear wall by being screwed at the corners thereof and which has at least one mounting housing at the contact point thereof with the edge of the lower plate.
  • the oven comprises at least one claw which is provided on the surface of the lower plate which is in contact with the fan sheet metal and which is fitted into said at least one mounting housing.
  • the oven comprises a catch which is provided on the side of the lower plate facing the front wall and which enables the lower plate to be mounted to the hidden tray, and a connection member which receives said catch and which is positioned on the hidden tray.
  • the oven comprises a fan sheet metal which is mounted to the rear wall by being screwed at the corners thereof and which has at least one mounting housing at the contact point thereof with the edge of the lower plate; at least one claw which is provided on the surface of the lower plate which is in contact with the fan sheet metal and which is fitted into said at least one mounting housing; a catch which is provided on the side of the lower plate facing the front wall and which enables the lower plate to be mounted to the hidden tray; and a connection member which receives said catch and which is positioned on the hidden tray.
  • the oven (1) of the present invention comprises a pair of side walls (2, 3); a rear wall (4); an upper wall (5); a lower wall (6); and a front wall (7).
  • the front wall (7) comprises a door.
  • a control panel is provided, which can be placed above, below or next to the door.
  • An arm (not shown in the figures) is positioned on the door so as to open the door from bottom to top, from top to bottom, from left to right or from right to left.
  • the oven (1) comprises a fan (8) which is positioned on the rear wall (4), and a circular heater (9) which is disposed around the fan (8).
  • a fan sheet metal (10) which is mounted on the rear wall (4) by being screwed at the corners is provided in front of said fan (8) and the heater (9).
  • the oven (1) comprises an oven compartment (11) which is defined by the side walls (2, 3), a rear wall (4), an upper wall (5), a lower wall (6) and a front wall (7).
  • An oven shelf (12) is supported by any support member so as to be placed in the oven compartment (11).
  • the oven shelf (12) is a standard oven grill.
  • support members are positioned on the side walls (2, 3) so as to align with each other and face each other.
  • the oven shelf (12) is placed on said support members and is positioned in the oven compartment (11).
  • a large number of oven shelves (12) can be placed in the oven compartment (11) parallel to each other in the horizontal plane with a certain space therebetween.
  • the oven (1) comprises an upper plate (13) which is placed under the upper wall (5) and a lower plate (14) which is placed on the lower wall (6).
  • Said upper plate (13) and lower plate (14) comprise a plurality of jet nozzles (15) arranged thereon in rows and columns.
  • Said jet nozzles (15) are configured to transmit hot or cold impingement air towards the oven shelf (12) at a high speed. Relatively hot air entering the middle region of the fan sheet metal (10) passes through the fan (8) and the heater (9) so as to be accelerated after passing through the upper plate (13) and the lower plate (14) to be directed onto the foodstuff surface.
  • the jet nozzles (15) are shaped so as to form a flow pattern which enhances heat transfer on the surface of the foodstuff.
  • the jet nozzle (15) is circular and has a cross-section narrowing down from the surface of the lower plate (14) upwards. Thus, a more homogeneous and high heat transfer distribution is obtained, which enables the foodstuffs to be cooked homogeneously and more quickly in the oven (1).
  • the oven (1) comprises a plurality of slits (16) which are positioned in successive rows and columns among the plurality of jet nozzles (15) on the lower plate (14) so as to allow the passage of liquids which may flow from the foodstuffs; and a hidden tray (17) which is positioned under the lower plate (14) and which collects the liquids flowing through said slits (16). There is a gap between said hidden tray (17) and the lower plate (14) through which hot air passes. The grease and foodstuff liquids flowing through said slits (16) are collected in the hidden tray (17) disposed under the lower plate (14). Thus, since grease and foodstuff liquids do not come into direct contact with the hidden heater on the lower wall (6), the problem of said liquids being burnt or being difficult to clean is prevented.
  • the lower plate (14) when viewed from the front wall (7), has an inclination towards the rear wall (4).
  • the liquids from the foodstuffs remaining on the surface of the lower plate (14) are directed to the slits among the jet nozzles, and from there to the hidden tray (17).
  • said slits (16) provide an exit for the air, thus strengthening the weak air flow region among the jet nozzles (15).
  • the slits (16) are positioned on the lower plate (14) so as to remain among the jet nozzles (15) at certain intervals. Said slits (16) can be positioned on the lower plate (14) in a disordered manner.
  • said slits (16) are arranged as successive rows and columns on the lower plate (14) so as to cover the entire surface.
  • said slits (16) are arranged as successive rows and columns among the jet nozzles (15) in an area corresponding to the center region of the lower plate (14).
  • said slits (16) are configured so as to have different or same dimensions in order to enable the hot air to be dispersed in a homogeneous speed.
  • the jet nozzles (15) through which the air exits may have the same or different dimensions.
  • the dimensions of the jet nozzles (15) can also be adjusted to provide a homogeneous distribution of hot air.
  • the height of the hidden tray (17) disposed under the lower plate (14) decreases from the rear wall (4) towards the front wall (7) depending on the placement.
  • the ratio of the front height (h1) of the hidden tray (17) to the rear height (h2) thereof is between 0.3 and 0.8.
  • the side walls (2, 3) comprise at least two carrier members with at least one on each side wall (2, 3) in a positioned aligned with the hidden tray (17) and the lower plate (14) so as to allow the placement of the hidden tray (17) and the lower plate (14).
  • the carrier member is a rail system.
  • the hidden tray (17) and the lower plate (14) are required to be removed and cleaned periodically.
  • the hidden tray (17) and the lower plate (14) are removed and cleaned separately as shown in Figure 6 .
  • the claw (14.1) on the lower plate (14) is removed from the mounting housing (10.1) on the fan sheet metal (10), and the lower plate (14) is cleaned separately.
  • connection member (17.1) which enables the hidden tray (18) to be gripped and pulled out of the oven compartment (11) by being pulled.
  • the hidden tray (17) is taken out of the oven compartment (11) and cleaned by means of this sliding structure.
  • the hidden tray (17) and the lower plate (14) are removed and cleaned together.
  • the bottom plate (14) is mounted to the hidden tray (17) by engaging a catch (14.2), which is positioned on the part of the lower plate (14) facing the front wall (7), with the connection member (17.1) positioned on the part of the hidden tray (17) facing the front wall (7) so as to correspond to the catch (14.2).
  • the connection of said catch (14.2) is provided by a spring mechanism. Said spring mechanism has a structure which can be gripped by the user by hand. The user takes out the hidden tray (17) and the lower plate (14) by holding this spring mechanism. Then, he/she separates the hidden tray (17) and the lower plate (14) from each other by lifting the catch (14.2). After being cleaned, the hidden tray (17) and the lower plate (14) are connected to each other outside and placed in the oven compartment (11).
