TH16129A - Espresso machine for coffee flavoring - Google Patents

Abstract

The coffee maker has a brewing barrel (1) with a cylindrical bore (2) and a piston (3,4). Two pistons (1) and a piston (3,4) are positioned for relative movement. Each other In the brewing position, the brewing barrel (1) and the two pistons (3,4) are located after the brewing chamber (5) in order to scald the ground coffee within it by feeding the pressurized water. This water is fed to the brewing room (5) via connecting devices. (18) and through the through-hole through the wall of the brewing barrel (1) into the annular gap (14) formed between the compression plate (11) and the face (13) of the end of the second piston. (4) which faces the brewing chamber (5), through a filter device (32), a pipe (34) and a connection device (358), the coffee is released by aligning a gap (14), surface (13). Of the second piston (4) can be made without filter device The pressurized water supply to the gaps (19) creates a self-cleaning effect in the rear by the design without a filter device of the face (13) of the second piston tip. (4) Not only can the worn parts be removed But it can also produce a coffee machine with a more reasonable cost.

Claims (8)
