  • the present invention relates to a door for use in a household appliance, in particular an oven.
  • the present invention more particularly relates to a door with an intermediate glass pane.
  • the exposed parts of a household appliance must be generally kept well below dangerous temperature limits to protect the user from skin burns and scalding.
  • exposed parts such as the oven door is directly subjected to radiant heat emanated from the cooking chamber.
  • the handle and the outer glass pane of the oven door can easily get hot. Therefore, increased measures must be taken to cool down the oven door to safe temperatures.
  • an intermediate glass pane is arranged between the outer glass pane and an inner glass pane of the oven door to function as an additional thermal barrier.
  • the hot air inside the oven door can be discharged into the environment, for example, by natural convection via a ventilation hole formed in the oven door.
  • DE 101 43 925 A1 discloses a cooking appliance door.
  • This cooking appliance door includes an outer glass pane, an inner glass pane, and the intermediate glass pane.

  • the cooking appliance door further includes a frame which holds the outer glass pane and an inner glass pane.
  • the intermediate glass pane is inserted into a gap defined by a flange and an L-shaped profile which are circumferentially formed on the frame.
  • a drawback of the above conventional cooking appliance door is that a manufacturing of the frame involves assembly of several parts which incurs additional costs. Also the intermediate glass pane is susceptible to vibrations and breakage.
  • An objective of the present invention is to provide a door for use in an oven which overcomes the aforementioned drawbacks of the prior art and which is easy to manufacture and assemble.

  • each guide has protrusions which abut the lower surface and the upper surface of the intermediate glass pane.
  • the protrusions provide a relatively high friction to prevent the intermediate glass pane from sliding.
  • the protrusions firmly press onto the intermediate glass pane so as to diminish vibrations and prevent the intermediate glass pane from clattering or the like under load.
  • the protrusions of each guide are formed in a staggered arrangement to improve a grip.
  • each guide is reinforced with supporting ribs.
  • the supporting ribs prevent the mounting element from breakage when the intermediate glass pane exerts high forces onto the guide.
