AUTOMATIC COFFEE-MAKING MACHINE Russian patent published in 2009 - IPC A47J31/40 

FIELD: personal and household objects.

SUBSTANCE: automatic coffee-making machine has a slide-block, firmly attached to a housing. Boiling unit comprises top and bottom blocking elements, and a vertical pipe section. The top blocking element alternately moves into the boiling position, ready position and stop position. In the boiling position, the top blocking element passes into the pipe section so as to obtain a boiling chamber, and in the ready position - does not pass into the pipe section, and the axis of the top blocking element is level with the axis of the pipe section, and in the stop position - does not pass into the pipe section, and the axis of the top blocking element is not level with the axis of the pipe section. A rotating column attached to the top blocking element provides for movement in the axial direction and rotation about its axis. The rotating column has slide path, which has a first section, parallel the axis of the rotating column, and a second section which passes like a thread. The slide-block interacts with the first section for alternate reaching the boiling position and the ready position. The slide-block interacts with the second section for alternate reaching the ready position and the stop position.

EFFECT: simple design and simple boiling cycle.
