- the second cover element can be clipped to the first cover element.
- the first and second cover element can also be cemented with each other or otherwise connected with each other.
- the first cover element is substantially made of an optical clear transparent material and the second cover element is substantially made of an optical intransparent material or the first cover element is substantially made of an optical intransparent material and the second cover element is substantially made of an optical clear transparent material.
- the opening of the first cover element is as a rule substantially arranged in the centre of the first cover element and preferably substantially roundly, oval or angularly.
- the intransparent material is a metal or a metal alloy, in particular a stainless steel.
- the metal or the metal alloy can be enamelled, nickel-plated or chrome-plated. It is thus possible that the cover of the invention comprises stainless steel but in a minor amount than according to the state of the art.
- the transparent material of the cover is printed, in particular printed from behind.
- the rear side of the cover can be provided with at least one inscription which can be read by an operator and can contain information for the operator for example for positioning a backing tray in the cooking chamber or something else. Because the cover is printed from behind the front side of the cover to the cooking chamber is substantially plane and thus easily to clean. The printed rear side can as a rule not be contaminated by fat, oil, etc. and is not directly exposed to the heat of the cooking chamber.
- the cover is detachably arranged to the barrier.
- the cover can be for example put in a dishwasher for cleaning.
- the cover can be arranged to the barrier with at least one screw.
- the cover can additionally or alternatively comprise at least one snap-fit for arranging the cover detachably to the barrier, which snap-fit can be made of a metal or of a plastic material.
- the domestic appliance comprises at least one safety device which shuts down at least the fan and/or a heater behind the cover when the cover is detached.
- the safety device can comprise a safety switch which is operated when the cover is detached. For example an electrical circuit is opened by the safety switch what is recognized by a control unit of the domestic appliance which shuts the fan and/or a heater down.
