Layer for use in a domestic appliance
View Patent ↗Disclosed is a layer for use in a domestic appliance, based on a sol-gel precursor. This layer can be obtained by screen-printing and comprises an organosilane compound. The layer is obtained from a concentrated pre-polymerized sol-gel precursor. The layer can be used as an insulating layer or as a conductive layer in a heating element. Furthermore, the layer can be used for decorative purposes.
1. A layer for use in a domestic appliance, obtained by screen-printing, based on a sol-gel precursor and comprising an organosilane compound, wherein said layer is obtained from a concentrated prepolymerized sol-gel precursor comprising an organosilane compound and a solvent, an amount of solvent being less than 40%.
2. A layer according to claim 1 , wherein the amount of solvent is 15-25%.
3. A layer according to claim 1 , further comprising an insulating layer of a heating element.
4. A heating element at least comprising an electrically insulating layer and an electrically conductive layer, wherein the electrically insulating layer comprises a layer according to claim 1 .
5. A heating element according to claim 4 , wherein the electrically insulating layer comprises non-conductive particles.
6. A heating element according to claim 1 , wherein the electrically insulating layer comprises anisotropic, non-conductive particles.
7. A layer according to claim 1 , further comprising an electrically conductive layer of a heating element.
8. A heating element according to claim 4 , wherein the electrically conductive layer comprises a layer according to claim 1 .
9. A heating element according to claim 4 , wherein the electrically conductive layer comprises conductive and/or semi-conductive particles, as well as an amount of insulating particles in a quantity of 0-20% by volume.
10. A heating element according to claim 4 , wherein the electrically conductive layer comprises metal particles.
11. A heating element according to claim 4 , wherein the electrically conductive layer comprises silver or silver alloy particles.
12. A heating element according to claim 4 , wherein the electrically conductive layer comprises graphite or carbon-black particles.
13. A layer according to claim 1 , wherein the layer is a surface layer of a domestic appliance.
14. Domestic appliance comprising a layer according to claim 1 , wherein the domestic appliance comprises a hair dryer, a hair styler, a steamer, a steam cleaner, a garment cleaner, a heated ironing board, a facial steamer, a kettle, a pressurized boiler for system irons and cleaners, a coffee maker, a deep fat fryer, a rice cooker, a sterilizer, a hot-plate, a hot-pot, a grill, a space heater, a waffle iron, a toaster, an oven or a water flow heater.
