Abstract

Abstract The invention provides an espresso coffee machine comprising an electrically heated vessel with a removable tight-closing lid intended for receiving water, and a rising pipe one end of which opens out in the vicinity of the bottom of the vessel while the other end leads to a container arranged at a distance above the vessel intended for receiving ground coffee. Arranged on the lid is a pipe leading outside the vessel and connecting to the vessel interior via a valve which can be actuated outside the vessel. The lid pipe permits entry of dry steam into the machine to, for example, foam milk.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 157 words
An espresso coffee machine with an electrically heatable vessel having a removable tight-closing lid and intended for receiving water, and with a rising pipe, one end of which opens out in the vicinity of the bottom of the vessel and the other end of which leads to a container which is arranged at a distance directly above the vessel and is intended for receiving ground coffee and the water flow of which is controlled as a function of a specific steam pressure, wherein there is arranged on the lid a pipe which leads outside the vessel and which is connected to the interior of the vessel via a valve which can be actuated outside the vessel, and a space provided vertically above the lid but beneath the ground coffee container capable of accommodating a finished-coffee receiving vessel, the rising pipe having or forming a cooling device outside the vessel and the pipe being unconnected to the lid.
Claim 2
Dependent Claim 157 words
An espresso coffee machine with an electrically heatable vessel having a removable tight-closing lid and intended for receiving water, and with a rising pipe, one end of which opens out in the vicinity of the bottom of the vessel and the other end of which leads to a container which is arranged at a distance directly above the vessel and is intended for receiving ground coffee and the water flow of which is controlled as a function of a specific steam pressure, wherein there is arranged on the lid a pipe which leads outside the vessel and which is connected to the interior of the vessel via a valve which can be actuated outside the vessel, and a space provided vertically above the lid but beneath the ground coffee container capable of accommodating a finished-coffee receiving vessel, the rising pipe having or forming a cooling device outside the vessel and the pipe being unconnected to the lid.
Claim 3
Dependent Claim 36 words
An espresso coffee machine as claimed in claim 1, wherein, to form the cooling device, the rising pipe is surrounded outside the water vessel by more material, especially metal, than is required for the pipe wall.
Claim 4
Dependent Claim 31 words
An espresso coffee machine as claimed in claim 1 wherein, to form the cooling device, the rising pipe has outside the water vessel a greater length than the shortest length required.
