Abstract: A protective liner for use with a cooking top is provided. The protective liner includes a base sheet and additional sheets which are geometrically similar to the surface of a cooking top. The protective liner shields the cooking top or a portion thereof from soil. Housing holes in the sheets delimit an area for corresponding cooking devices. The upper sheets are removable, leaving the base sheet as a clean sheet to shield the cooking top. An associated system is provided in which a stove having a cooking top with a surface through which one or more cooking devices are disposed has a protective liner to protect the cooking top surface from soil. The sheets of the protective liner are removable such that when a particular sheet is removed, an immediately adjacent sheet provides a clean outer aspect of the cooking top.

Abstract: The present invention relates to a cooking top (1), in particular adapted to be used in a household environment, comprising at least one gas burner (40) which can be used with at least one fuel gas. The cooking top also comprises flame divider means (9) associated with the gas burner (40) and comprising at least one semi-permeable element (90), which is permeable to gaseous substances and substantially impermeable to liquid substances. The semi-permeable element (90) may be a micro-perforated sheet, a fibrous membrane, or a porous membrane.
