Definitions

  • the invention relates to a coffee machine according to the preamble of claim 1 and a water tank according to the preamble of claim 6.
  • Coffee machines of the prior art work on different principles.
  • the most common models are the so-called non-pressure coffee machines.
  • water flows from a reservoir into an electrically heated tube.
  • heated water is then forced through a riser to an outlet, over which the heated water then drips into a coffee filter. From this coffee filter, the filter coffee can then flow into a jug at atmospheric pressure.
  • This Kaffe ⁇ flour receiving device generally comprises a sieve for receiving the coffee.
  • the coffee grounds receiving device is arranged during operation in a region sealed off from the atmosphere, which can be referred to as a pressure chamber or brewing chamber.
  • the water for preparing the coffee is first of all transferred from a water container into a heatable intermediate container.

  • the holder provides a sealing surface, so that a pressure chamber can be formed. Furthermore, the holder has an outlet opening from which the coffee can escape. Furthermore, the coffee pad should be mounted in a manner in the holder, so that the flow through the coffee pad is not hindered. Such a coffee maker takes an intermediate position between see a conventional unpressurized coffee machine and an espresso machine.
  • the object of the invention is to provide a coffee machine and a pump holder for a coffee machine, so that a better vibration or vibration damping is achieved.

  • the vibrations generated by the pump must cover a long transmission path between the actual pump suspension and the attachment points, which favors the damping behavior of the arrangement.
  • the pump can ultimately be supported by the mounting points of the pump holder down, but is suspended from above. A direct vibration transmission to housing parts below the pump is prevented in this way.
  • the pump holder comprises two suspension elements, in which the pump is suspended over substantially horizontally extending pins. This allows a stable and effective in terms of vibration damping suspension of the pump.
