Arrangement of glass panels for a heat insulated oven door for a cooking oven
The present invention relates to a arrangement of at least two glass panels ( 12, 14, 16 ) for a heat insulated oven door ( 10 ) of a cooking oven. The arrangement of the glass panels ( 12, 14, 16 ) is provided as or for a window of the oven door ( 10 ). The large-area sides of said glass panels ( 12, 14, 16 ) are arranged in parallel. Two neighbored glass panels ( 12, 14, 16 ) are arranged with a predetermined distance from each other, so that an intermediate space ( 24, 24′, 24 ″) is formed between said neighbored glass panels ( 12, 14, 16 ).
1. A cooking oven comprising:
an oven cavity; and
an oven door including a front panel facing an ambient environment and an arrangement of at least three glass panels,
the arrangement of the glass panels being provided as or for a window of the oven door, large-area sides of said glass panels being arranged in parallel,
the glass panels being arranged a predetermined distance from each other, so that a first intermediate space and a second intermediate space are formed between adjacent glass panels,
a border of the first intermediate space being filled with a silicone sealing and a border of the second intermediate space being filled with a glass solder,
the first intermediate space and the second intermediate space being evacuated or filled with an inert gas,
the silicone sealing and/or the glass solder, respectively, being adapted to the behaviour of the glass panels at high temperatures to compensate for motions of the glass panels due to heat expansion and/or gas pressure, and
an inner glass panel of the at least three glass panels closing an open end of the oven cavity while the oven door is in a closed position.
2. The cooking oven according to claim 1 , wherein
the large-area sides of the glass panels have essentially the same sizes.
3. The cooking oven according to claim 1 , wherein
the silicone sealing is made of silicone foam.
4. The cooking oven according to claim 3 ,
the silicone foam comprising essentially closed pores.
5. The cooking oven according to claim 3 ,
said silicone foam comprising essentially open pores.
6. The cooking oven according to claim 5 , wherein
the silicone sealing is formed as a solid part, said silicone foam consisting essentially of open pores.
7. The cooking oven according to claim 5 , wherein
the silicone sealing consists essentially of silicone foam comprising open pores and comprises a gas barrier on a side that faces away from the first intermediate space or the second intermediate space between the adjacent glass panels.
8. The cooking oven according to claim 1 , wherein
the silicone sealing is formed as an elongated profile strip.
9. The cooking oven according to claim 1 , wherein
said first intermediate space is filled with an inert gas and said second intermediate space is evacuated.
10. The cooking oven according to claim 1 , wherein said second intermediate space is arranged towards the oven cavity.
11. The cooking oven according to claim 1 , wherein
a supporting structure is arranged in the evacuated second intermediate space.
12. The cooking oven according to claim 11 , wherein
the supporting structure includes a plurality of supporting elements comprising glass beads or glass cylinders.
13. The cooking oven according to claim 12 , wherein
the supporting elements are arranged according to a predetermined scheme and form a grid.
14. The cooking oven according to claim 1 , wherein an outer glass panel of the at least three glass panels is arranged behind the front panel of the oven door.
