Embodiment Construction

[0026] In the figures, the same elements or elements with the same function are denoted by the same reference numerals.

[0027] figure 1 The basic structure of the coffee machine 10 is shown with reference number 10 . This coffee machine comprises a removable water tank, to which a coupling valve 12 is associated. The water tank 11 is connected to a water pipe system 13 via a connection valve 12 , wherein water can be delivered from the water tank 11 by means of a delivery pump 14 . The pipe 15 of the water pipe system 13 leads from the water tank 11 via a delivery pump 14 to a heating device 16 (heating block) and thereafter divides into a pipe 17 leading to a cooking unit 18 and a pipe 19 leading to a steam generator 20 . The line 19 is preceded by a valve 21 . A drain valve 22 is assigned to the cooking unit 18 in a known manner, via which the cooking unit 18 can be fluidically connected to a receiving tray 23 in order to press out residues, for example after a cooking ...

Abstract

The invention relates to a coffee machine (10), in particular a fully automatic coffee machine, comprising a water tank (11), also a heating device (16) for heating up water, also a brewing unit (18) for subjecting ground coffee beans to extraction by means of the water heated by the heating device (16), also a water-line system (13) comprising at least one water line, and also a delivery pump (14) for delivering water out of the water tank (11) through the water-line system (13). According to the invention, it is provided that a chamber (25) is, or may be provided for a chemical active substance, in particular a descaling and / or cleaning agent, it being possible for this chamber to be connected and / or linked up to the water-line system (13), manually or automatically, such that water can be delivered out of the water tank (11), by means of the delivery pump (14), into the water-line system (13) through the chamber (25). The invention also concerns a method for operating a coffee machine (10).

Description

technical field [0001] The invention relates to a coffee machine, in particular a fully automatic coffee machine, according to the preamble of claim 1, comprising a water tank, heating means for heating the water, cooking means for filtering out ground coffee beans by means of the water heated by the heating means. A boiling unit, a plumbing system comprising at least one water pipe, and a transfer pump for conveying water from a water tank through the plumbing system. Background technique [0002] Fully automatic coffee machines are generally known. The fully automatic coffee machine comprises a water tank, a heating device, a cooking unit and a delivery pump, with which water can be conveyed from the water tank through the heating device into the cooking unit, in which heated water can be filtered Discharge ground coffee (ground coffee beans). The coffee product then leaves the brewing unit in the direction of the drinking container. Usually, fully automatic coffee mach...
