Abstract
The espresso machine works with filter capsules and has a scalding unit (4) with two scalding chamber parts (2, 3) which can be moved relative to each other between an opening position and a closing position. The scalding chamber parts (2, 3) enclose between them in their opening position a gap (1). The gap (1) provided for throwing in the filter capsules can be closed by a swivel-type upper lever (15) and towards the bottom also by a swivel-type lower lever (18). Preferably the machine is equipped with a drain pipe (14) the angle of which can be adjusted. The adjustability of the drain pipe (14) permits the use of larger cups whereas spilling of espresso past the cup is avoided when smaller cups are used. Preferably the drain pipe is mounted in the base of a drain tub.
