<p>The hob (1) has an operating knob (4) for controlling combustion power of a gas burner (2), and a closure element for supplying primary air to the gas burner. The closure element is mechanically coupled to the operating knob. An opening is provided in the closure element for passage of the primary air, where the cross section of the opening depends on position of the operating knob. The closure element is formed as a flap (6), and the operating knob is arranged above a plate (5), where the closure element and the plate are made of glass-ceramic materials.</p> |
