  • the present invention relates to a compact coffee machine with an integrated coffee grinder. Coffee machines with integrated grinders are well known.
  • Configurations are also known in which the integrated grinder is positioned in such a way that the coffee powder falls directly into the filter holder, and the subsequent infusion phase is possible without having to move the filter holder thanks to a mobile infusion head, moved manually or by means of a motor, in such a way as to couple with the filter holder, guaranteeing the hydraulic seal typical of espresso coffee preparation.
  • the technical task that the present invention proposes is, therefore, to realise a coffee machine with an integrated coffee grinder that eliminates the complained of technical drawbacks of the known technique.
