Definitions

  • the invention relates to an espresso machine for preparing coffee beverages with a coupling device for establishing a flow connection between a liquid container that can be placed on the coupling device and a liquid line.

  • the coffee machine described therein has a receptacle for an external water supply source, such as a water bottle or a water can.
  • This water container should now ensure a uniform quality of the coffee due to the constant consistency of the water used.
  • the coffee machine has a valve connected to the receptacle for the water bottle for the controlled delivery of the water into the coffee machine.
