Definitions

  • the present invention relates to a cooking device comprising a panel.
  • Cooking devices comprise a panel whereon buttons and displays are situated. Since the body of the cooking device reaches high temperatures, the panel is preferably produced from sheet metal material. Due to both aesthetic concerns and the components disposed on the panel, the panel is required to have a special form. However, during the production of the panel, difficulties are encountered about shaping the sheet metal material.
  • the sheet metal material is generally shaped by using the deep drawing process.
  • problems such as tearing are encountered.
  • the deep drawing process cannot be performed by using a single type of mould and the need of using different moulds according to different sheet metal materials used arises. Such problems increase the production cost of the panel.
  • the aim of the present invention is the realization of a cooking device comprising a panel that production method of which is simplified and the production cost of which is reduced.
  • the cooking device panel of the present invention is formed by bending a flat sheet metal in the shape of a box, one face of which is open.
  • the panel has an almost rectangular front wall whereon buttons are disposed, and two opposite side walls, a top wall and a bottom wall which surround the four sides of the front wall.
  • the panel comprises cut-outs which are formed by cutting four corners of the sheet, and more than one arc-shaped recess which starts from the junction points of the cut-outs and the top wall or bottom wall, and which is over at the top wall or bottom wall of the panel when the sheet is folded.
  • the panel comprises more than one slit which is formed by folding the sheet vertically along the first folding line extending parallel to the long edges of the sheet, and by bending the sheet by rounding it along the second folding line extending vertically to the first folding line, and which remains between the panel side wall edges that get close to the bottom wall and the top wall.
  • the panel comprises flaps which remain between the first folding line and the first cutting line, and which are formed by folding the sheet along the first folding line. When the sheet is folded along the second folding line, the flaps extend towards the bottom wall or top wall.
  • the panel furthermore, comprises protrusions which are located on the flaps and which extend towards the slits when the sheet is folded by being rounded along the second folding line, and a hole which is located on the protrusions and which serves to fasten the side walls onto the bottom wall or top wall.
  • a hole which is located on the protrusions and which serves to fasten the side walls onto the bottom wall or top wall.
  • holes which overlap with the holes, are situated on the top wall and bottom wall of the panel.
  • the panel comprises almost circular openings which are located at the end of the recesses such that the openings will remain on the bottom wall and top wall.
  • the risks such as tearing and splitting, which can occur on the sheet during the forming of the panel, are minimized.
  • problems such as tearing and splitting, which occur on the sheet due to the plastic deformations occurring on the sheet metal material during the production of the sheet, are prevented from occurring and thus, cost advantage is provided.
  • the need of using different moulds for different sheet metal materials due to different ductility of each material is also eliminated.

  • a cooking device (1) of the present invention comprises a panel (2) that is formed by cutting and bending a rectangular sheet metal (S) in the form of an open-top rectangular prism, and that has a front wall (3) whereon the control buttons are disposed, and two side walls (4), a bottom wall (5) and a top wall (6) which surround the front wall (3).
  • S rectangular sheet metal
  • the panel (2) comprises almost square cut-outs (7) which are located at four corners of the sheet (S) and which are formed by cutting the sheet (S) along a first cutting line (C1) that extends parallel to the long edges of the sheet (S) and vertically to the short edge of the sheet (S), and along a second cutting line (C2) that is vertical to the first cutting line (C1); and more than one arc-shaped recess (8) which is located at the junction point of the cutting lines (C1 , C2) that form the cut-outs (7), and which extends towards between the sheet (S) portions that form the front wall (3) and the top wall (6) or bottom wall (5) of the panel (2) when the sheet (S) is folded.
  • the recess (8) is shaped almost as a quarter arc. The recess (8) prevents problems such as tearing, which can occur when the sheet (S) is folded to be shaped as a panel (2), from occurring.
  • the panel (2) comprises flaps (10) which remain between the first folding line (F1) and the first cutting line (C1) that extend parallel to the long edges of the sheet (S), and which are formed on the side walls (4) by folding the sheet (S) along the first folding line (F1).
  • the distance remaining between the first folding line (F1) and the first cutting line (C1) is equal to the width of the flaps (10).
  • the flaps (10) extend towards the bottom wall (5) or top wall (6) from the side wall (4), which is formed by bending the sheet (S) by rounding it along the second folding lines (F2) that extend parallel to the short edges of the sheet (S) and that remain between the first folding lines (F1).
  • the panel (2) furthermore, comprises more than one slit (9) which is formed by folding the sheet (S) vertically along the first folding lines (F1) and by bending the sheet (S) by rounding it along the second folding line (F2), and which remains between the flaps (10) and the top wall (6) or bottom wall (5).
  • the first folding line (F1) is also the line that separates the front wall (3) from the top wall (6) and bottom wall (5).
  • the second folding line (F2) is the line that separates the front wall (3) from the side walls (4).
  • the sheet (S) is folded along the first folding line (F1 ) angularly with respect to the front wall (3) such that the folding angle will be almost equal to 90 degrees, and thus, the bottom wall (5) and top wall (6) of the panel (2) and the flaps (10) are formed.
  • the panel (2) side walls (4) By bending the sheet (S) along the second folding line (F2) by means of a round support means, the panel (2) side walls (4), the corners of which are rounded, are formed.
  • the recesses (8) extend until the level of the second folding line (F2). Since the side walls (4) are bent by being rounded and the recesses (8) are shaped as a quarter arc, the slits (9) and the recesses (8) are shaped as an upside-down "J" together.
  • the slits (9) By forming the slits (9) such that they will remain on the top wall (6) and bottom wall (5) of the panel (2), problems such as tearing and splitting, which can occur on the sheet (S) due to the plastic deformations occurring during the providing of the panel (2) by bending the sheet (S), are prevented.

  • the panel (2) production is performed by using different sheet metal materials, the need of using different moulds for different sheet metal materials due to different ductilities of each material is also eliminated.
  • Performing the panel (2) production by cutting-bending method by forming slits (9) on the bottom wall (5) and top wall (6) provides significant cost advantages particularly during the panel (2) production from materials such as inox material, which requires excessive force to be applied for shaping the panel (2).
  • the panel (2) furthermore, comprises more than one protrusion (11), which extends towards the slit (9) when the sheet (S) is folded by being rounded along the second folding line (F2), on the flaps (10).
