Definitions

  • the invention relates to an oven with a cooking chamber and a furnace door closing this, which is traversed by a flow channel having an opening disposed on the front side of the oven for cooling air below the oven door.
  • the US 2 438 035 A describes a gas oven with a cooking chamber and this closing oven door.
  • a cover is arranged, wherein between the oven door and the cover a flow channel is formed.
  • the flow channel communicates with a shaft which leads to a fume hood at the back of the oven.
  • the US 2007/0158330 A1 describes an electric furnace in which by means of a blower in an oven door can be adjusted downwards out of the oven door air flow.
  • a flow channel is arranged within the oven door operatively heated cooking chamber, which has an inflow opening at the top of the oven door and at the top of the oven door frontally into the open outflow opening whereby the furnace front cooling air flow by natural convection from cooler to warmer Area is caused to a more or less sufficient flow rate within the oven door.
  • the present invention is therefore based on the object, an oven of the type mentioned in such a way that with little or even no expense of funds for forced air flow and thermal insulation, a considerable reduction of the windshield contact temperature is obtained with complete avoidance of a front side hot air flow.
  • the flow path consisting of the oven door flow channel and the housing-internal flow path extends on the one hand in a substantially flow direction while avoiding drastic changes in direction, e.g. Reverse points that is flow barriers and flow congestion, and on the other hand from bottom to top, so that even by natural, forced convection sufficient cooling air flow rate can be achieved, leaving the front of the oven untouched.
  • a fan is arranged in the flow path, is associated with the suction side of the flow channel in the oven door. Due to the streamlined air flow, the blower power of the fan and thus its operating noise can be kept at a low level.
  • an air guide element is arranged between the flow channel in the oven door and the flow path, which at least right angles the cooling air from the flow channel, ie with low flow resistance without drastic change of direction in the flow path and there to the outflow.
  • the invention provides that the cooking chamber an exhaust duct for the resulting oven operation is connected to the vapors, which opens separately from the flow path at the oven back to the outside.
  • the present invention is thus universally advantageous applicable to different types of ovens, especially those with a not provided with thermal insulation door front, for example, with a see-through window having glass front, or For example, in ovens with special heat-sensitive electronic components or with heat-resistant eg mechanical control components.
  • an oven which has a furnace housing 1, in which a cooking chamber 2 within a cuboid furnace muffle 3 and above a switch room 4 is arranged.
  • a switch room 4 Connected to the switch room 4 or to its control device (not shown) with electrical or electronic components is an operating and display panel 22 on the front side of the oven housing 1.
  • Attached to the oven housing 1 is e.g. a hob 5 with hotplates, not shown.
  • the oven muffle 3 open to the front side of the oven is closable by an oven door 6 with handle 7.
  • a flow channel 8 which is connected by ventilation to an opening 9 located below the oven door 6 and above a drawer 19, which communicates with the outside air, as indicated by arrows 10.
  • Illustrated by arrows 11 is a vertical cooling air flow which, when operated on the oven, is connected to e.g. designed as a glass front of a see-through window front surface of the oven door 6 pending amount of heat to dissipate to the outside.
  • the cooling air flow 11 is deflected at an inclined air guide element 12 in an example.
  • the relevant flow profile is illustrated by arrows 16.
  • an exhaust duct 20 Separated from the air duct 8/13 is an exhaust duct 20 which is connected on the one hand to the furnace muffle 3 and on the other hand in the back of the hob 5 opens into the open. Through this exhaust duct 20 of the operationally in the cooking chamber 2 forming hot vapors is discharged according to the flow arrows 21st
