Abstract: The present invention relates to fan cover (6), in particular a fan cover (6) for a cooking appliance (1), obtainable by a process characterised by the following steps, a) providing a fan cover (6) having an inner surface (7a), an outer surface (7b) and at least one opening (8) allowing a fluid to flow through, b) pretreating of at least the inner surface (7a) of the fan cover (6) for providing a surface having a roughness being suitable for applying a non-stick and/or non-wetting coating (12) by mechanical treatment, physical treatment or chemical treatment, in particular by sandblasting and/or laser treatment and/or an enamelling process to form a ground layer (13), c) applying the non-stick and/or non-wetting coating (12) to the inner surface (7a) of the fan cover (6) or the surface (14a) of the ground layer (13), wherein the non-stick and/or non-wetting coating (12) comprises at least one layer (17) that is obtained by a sol-gel process from a first composition comprising a silica sol and a silane. The invention further relates to a cooking appliance (1), in particular a domestic oven comprising such a fan cover (6) and a method for manufacturing such a fan cover (6).

Abstract: The present invention relates to component, in particular a top plate (2) for a gas hob (1) and/or a burner cap (6a, 6b) of a gas burner (5a, 5b) for a gas hob (1), having a non-stick and/or non-wetting coating (12) obtainable by a process characterised by the following steps, a) providing a component, in particular a top plate (2) and/or a burner cap (6a, 6b), having an upper surface (7a) and a bottom surface (11b), b) preferably, pretreating of at least the upper surface of the component, in particular the top plate or the burner cap, for providing a surface having a roughness being suitable for applying a non-stick and/or non-wetting coating, by mechanical treatment, physical treatment or chemical treatment, in particular by sand-blasting and/or laser treatment and/or a surface activation treatment, particularly a plasma treatment, and/or an enameling process to form a ground layer (13), thus applying an enamel layer onto the upper surface of the component, in particular the top plate or the burner cap, c) applying the non-stick and/or non-wetting coating (12) to the upper surface (11a) of the component, in particular a top plate (2) and/or a burner cap (6a, 6b), or the surface (14a) of the ground layer (13), wherein the non-stick and/or non-wetting coating (12) comprises at least one layer (17) that is obtained by a sol-gel process from a first composition comprising a silica sol and a silane. The invention further relates to a cooking appliance (1), in particular a gas hob comprising such a component, in particular a top plate (2) and/or a burner cap (6a, 6b), and a method for manufacturing such a component, in particular a top plate (2) and/or a burner cap (6a, 6b).

Abstract: The present invention relates to a sealing system for an oven cavity (10) of an oven, in particular of a cooking oven. The sealing system includes an outer steam-tight gasket (20) attachable or attached at a front frame (26), which encloses a cavity frame (12) of the oven cavity, which in turn encloses a front opening of said oven cavity (10). The sealing system includes an inner heat resistant gasket (18) attachable or attached at the cavity frame (12) and/or at the front frame (26), so that the inner heat resistant gasket (18) is aligned at least partially at the cavity frame (12) and at an inner panel (16) of an oven door (14) for closing the oven cavity (10) in a closed state of said oven door (14). The sealing system includes a gap sealing (19) arrangeable or arranged within a gap between the cavity frame (12) and the front frame (26), so that the gap sealing (19) encloses completely or partially the cavity frame (12). The inner heat resistant gasket (18) and the outer steam-tight gasket (20) are attachable or attached in such a way, that said inner heat resistant gasket (18) and outer steam-tight gasket (20) are aligned at the inner panel (16) of the oven door (14) at least in the closed state of said oven door (14).
