Improvements in electric coffee machines for individual use, characterized by having under the water tank, a cylindrical kettle, with hollow core, eccentric and also cylindrical; heated by a thermoelectric outer shell, and connected to the tank by two vertical tubes, one tearing off flush with the upper base of the kettle, and the other from the bottom thereof; both reaching the same height inside the upper tank; and the second one connected to the horizontal tube for the discharge of the water vapor mixture onto the coffee powder; the access valve to this branch automatically closes when opening the upper mouths of both vertical tubes, and vice versa; this synchronism is solved by a single articulated control lever with a central rod which, penetrating inside the upper tank, is connected to a disc or plate provided with lower elastic flat valves, which coincide and cover the upper mouths of the vertical tubes, and provided, the one corresponding to the tube that penetrates to the bottom of the kettle, of a rigid rod, with lateral stop to push the stem of the elastic reaction valve, to access the side discharge tube.
