FIELD: self-cleaning covers for devices for brewing, roasting, baking and grilling, which are polluted with remainders of foodstuffs during operation. ^ SUBSTANCE: the cover ensures satisfactory binding of cover with substrate, its impact resistance, chemical stability, resistance to temperature falls, and also resistance to scratching and includes (a) porous particles A, being particles of thermo-stable and chemically stable porous oxides, carbides and metal nitrides, and having dimension (particle diameter) ranging from 5 to 100 mcm and (b) binding substrate, being an inorganic polymer or inorganic substance, capable of resisting temperatures up to 500°C for extensive time spans, while porous particles A do not contain solid or liquid secondary phase in their pores "a", and volumetric share of binding substance ranges from 5 to 40%. ^ EFFECT: simplified removal of pollutions, surface of device or part of device looks clean without mechanical cleaning. ^ 2 cl, 1 dwg |
