Cooking compartment door of a cooking oven having a pyrolysis function
View Patent ↗A cooking compartment door of a cooking oven having a pyrolysis function in the cooking compartment, includes a borosilicate glass pane forming at least a portion of the cooking compartment door. The borosilicate glass pane is provided at least in sections with a colored layer. The colored layer provides impact resistance to the borosilicate glass pane by being applied to the surface of the borosilicate glass pane on the side opposite the cooking compartment. The colored layer is resistant to temperatures up to four hundred degrees Celsius and is not joined to the borosilicate glass pane surface by melting.
1. A cooking compartment door of a cooking oven having a pyrolysis function in a cooking compartment therein, comprising:
a borosilicate glass pane forming at least a portion of the cooking compartment door, said pane provided at least in sections with at least one colored layer;
said cooking compartment door closing the cooking compartment on a first side thereof;
said colored layer applied to the surface of said borosilicate glass pane on a second opposite side of said door facing away from said cooking compartment; and
said colored layer applied to said surface of said borosilicate glass pane at a temperature of about one hundred fifty (150) degrees Celsius to about two hundred (200) degrees Celsius wherein said colored layer is applied without melting and joined to said pane and wherein said colored layer is resistant to temperatures at least up to about four hundred (400) degrees Celsius.
2. The cooking compartment door according to claim 1 , including said colored layer is applied and substantially bonded to said surface of said borosilicate glass pane with at least one of an organic and an inorganic binder.
3. The cooking compartment door according to claim 2 , including said organic binder is at least one of a silicone resin and a fluoropolymer.
4. The cooking compartment door according to claim 2 , including said organic binder is at least one of a water glass binder and a sol gel binder.
5. The cooking compartment door according to claim 1 , including said colored layer is applied in a structured fashion to said surface by screen printing.
6. The cooking compartment door according to claim 1 , including said colored layer applied to said surface of said borosilicate glass pane without melting is combined with a coating fused to said surface.
7. The cooking compartment door according to claim 1 , including at least one further layer associated with said colored layer is a barrier layer for protecting said colored layer deposited on said surface of said borosilicate glass pane prior to applying said colored layer.
8. The cooking compartment door according to claim 7 , including said barrier layer protects said colored layer at least by one of protecting said colored layer from the penetration of liquid media into said colored layer and providing mechanical protection for said colored layer.
9. The cooking compartment door according to claim 1 , including said one further layer substantially inhibits incident infrared radiation on to said colored layer.
10. The cooking compartment door according to claim 1 , including at least two further layers, one of said further layers substantially inhibits incident infrared radiation on to said colored layer and the other of said further layers is a barrier layer for protecting said colored layer deposited on prior to applying said colored layer.
11. The cooking compartment door according to claim 10 , including said incident infrared radiation inhibiting layer is deposited on said surface of said borosilicate glass pane prior to applying said barrier layer.
12. The cooking compartment door according to claim 1 , including said colored layer is applied in at least one of a grid form and a lettered form to said surface.
