Definitions

  • a vented oven door for a domestic cooking oven The present invention relates to a vented oven door for a domestic cooking oven. Further, the present invention relates to a domestic cooking oven with a vented oven door according to the preamble of claim 7.
  • the vented oven door of the cooking oven allows low temperatures at the outer side of the oven door, so that there is no danger of being burnt for the user of the cooking oven.
  • the heat transfer from an inner glass panel being in contact with the oven cavity to an outer glass panel being in contact with the ambient is a combination of three different heat transfer modes. There is heat radiation from the surfaces of the inner glass panel, heat convection within the inner space of the oven door and heat conduction within the glasses of the glass panels.
  • a forced convection cools down the glass panels.
  • the cooling channel sucks cool air from the ambient through the inner space of the oven door.
  • the cooling channel may be arranged on the top wall of the oven cavity and the cool air streams upwards through the inner space of the oven door .
  • EP 1 972 855 Al discloses a cooking oven with an air cooled oven door.
  • the oven door includes an inner and outer door channel.
  • the inner door channel is connected to the suction side of air moving means, so that an air flow rises through said inner door channel to a suction duct of the air moving means. Then the air stream is blown out by the air moving means, wherein said air stream passes an upper end of the outer door channel without passing through the outer door channel.
  • the hot surfaces of the glass panel being in direct with the oven cavity are cooled down, so that also the oven cavity is undesirably cooled down. This results in low cooking performances and high energy consumption.
  • the object of the present invention is achieved by the vented oven door for a domestic cooking oven according to claim 1.
  • the present invention relates to the vented oven door for the domestic cooking oven, wherein:
  • the oven door comprises at least three glass panels
  • the inner space of the oven door is subdivided into at least two door channels by the at least three glass panels
  • At least one upper opening of at least one outer door channel is connected or connectable to a suction of a cooling channel with air moving means in a closed state of the oven door
  • At least one upper opening of at least one inner door channel is connected or connectable to the ambient on the one hand and an exhaust of the cooling channel on the other hand in the closed state of the oven door, so that air from the inner door channel is entrained by the air from the exhaust.
  • the main idea of the present invention is the forced heat convection in the outer door channel of the oven door on the one hand and the entrainment of the air stream from the inner door channel by the air stream from the cooling channel on the other hand. Additionally, the air stream from the inner door channel is driven by the natural heat convection flow due to the temperature gradient. This constellation allows an intensive cool- ing process in the outer portion of the oven door and prevents an intensive cooling down of the inner side of oven door, so that energy can be saved.
  • the oven door comprises a door cap defining at least one upper opening of the outer door channel.
  • the oven door may comprise a door cap defining at least one upper opening of the inner door channel.
  • the door cap is producible by low costs.
  • at least one of the door channels is aligned along a vertical direction. Further, at least one of the door channels may span nearly the complete width of the oven door. This contributes to an efficient cooling down.
  • the glass panels are arranged plane-parallel. Alternatively, the glass panels may be slanted, so that the cross section of the door channels can vary.
  • the object of the present invention is further achieved by a do- mestic cooking oven according to claim 7.
  • the domestic cooking oven according to the present invention comprises a vented oven door and a cooling channel with air moving means, at least one suction and at least one exhaust, the cooking oven comprises at least one oven door as described above .
  • the cooling channel is arranged on a top wall of an oven cavity.
  • FIG 1 illustrates a schematic sectional side view of an upper portion of a vented oven door for a domestic oven accord ing to a preferred embodiment of the present invention
  • FIG 2 illustrates the schematic sectional side view of the upper portion of the vented oven door with pictured air- streams according to the preferred embodiment of the pre sent invention.
  • FIG 1 illustrates a schematic sectional side view of an upper portion of a vented oven door 10 for a domestic oven according to a preferred embodiment of the present invention.
  • the oven door 10 is a closed state.
  • the oven door 10 includes an outer glass panel 12, a central glass panel 14 and an inner glass panel 16.
  • the outer glass panel 12, the central glass panel 14 and the inner glass panel 16 are arranged plane-parallel to each other.
  • An outer door channel 18 is arranged between the outer glass panel 12 and the central glass panel 14.
  • an inner door channel 20 is arranged between the central glass panel 14 and the inner glass panel 16.
  • the outer door channel 18 and the inner door channel 20 are aligned along vertical directions within the oven door 10.
  • the outer door channel 18 and the inner door channel 20 span nearly the complete width of the oven door 10.
  • a door cap 22 is arranged on the upper side of the oven door 10.
  • the structure of the door cap 22 defines the upper openings of the outer door channel 18 and the inner door channel 20.
  • the upper opening of the outer door channel 18 is substantially directed to the inner side of the oven door 10.
  • the upper opening of the inner door channel 20 is directed to the outer side of the oven door 10 and to the ambient.
  • a cooling channel with air moving means is arranged on the top wall of the oven cavity.
  • a suction 24 and an exhaust 26 of the cooling channel are arranged above an opening of the oven cavity. In the closed state of the oven door 10 the suction 24 of the cooling channel is arranged besides the upper end of said oven door 10. Further, the exhaust 26 of the cooling channel is arranged above the upper end of the oven door 10 in the closed state of said oven door 10.
  • the suction 24 and the exhaust 26 of the cooling channel span nearly the complete width of the oven door 10.
  • the upper opening of the inner door channel 20 is connected to the ambient on the one hand and to the exhaust 26 of the cooling channel on the other in the closed state of the oven door 10.
  • This constellation results in an entrainment of the air from the inner door channel 20 by the air stream form the exhaust 26.
  • the air from the inner door channel 20 is entrained to the ambient.
  • FIG 2 illustrates the schematic sectional side view of the upper portion of the vented oven door 10 with pictured airstreams 28, 30 and 32 according to the preferred embodiment of the present invention.
