Pot sensor for gas hob unit has vertically moving slider depressed by cooking vessel which opens gas supply valve

摘要

The sensing element (17) extends above the hob surface level (53) and closes the gas ball valve (33) by springs (19,43). A cooking vessel in place closes a gap (a) and depresses the sensing element and the valve ball (41) to allow gas from the mixing tube (13) to pass through the outlet channels (49).
