Abstract:
A safety device of a steam-frothing machine for producing a frothy beverage, with the machine having a substantially vertically oriented steam pipe that is connected to a steam generator and that has a steam discharge exit adjacent its lower end, and having a frothing head mounted on and normally enclosing the steam discharge opening; and wherein:the safety device comprises a hollow body that is pushed onto the end of the steam pipe, and which, in an enabling position when the frothing head is mounted, permits an essentially downward steam discharge, while essentially blocking a downward steam discharge when in a position other than the enabling position of the hollow body; the hollow body is a sliding sleeve that is mounted on the steam pipe and is automatically pushed into the blocking position due to biasing by a spring mounted on the steam pipe when the frothing head is removed from the steam pipe, in which blocking position it causes blocking of the discharge of steam from the steam discharge opening; and the sleeve is pushed into the enabling position when the frothing head is pushed onto the steam pipe, in which enabling position the discharge of steam from the steam discharge opening is enabled.
