US 2004/0105985 A1 · Cleaning-friendly apparatus with an easily cleanable, heat-resistant surface coating

Abstract

The cleaning-friendly apparatus, such as a household kitchen appliance, which is suitable for heating food and/or in direct connection with these units, has a suitable long-lasting or permanent easily cleaned coating on its surfaces that are accessible to dirt. In order to provide this easily cleaned coating a mixture is applied to these surfaces, which contains a hydrolyzable, network-forming gel and a hydrophobic substance. The gel is preferably formed from SiO2, Al2O3, Fe2O3, In2O3, SnO2, ZrO2, B2O3 and/or TiO2. The hydrophobic substance is preferably chemically combined with the gel network.
