  • liquid treatment agents can be metered by a metering pump, for example.
  • the liquid treatment agent may also have solid, in particular pulverulent, constituents.
  • Non-liquid treatment agents are, for example, pulverulent treatment agents which are filled in the dry state by a user. Such non-liquid treatment agents can also be sold in compressed form.
  • the cup receptacle is arranged between the container receptacle and the dispensing chamber, that between the container receptacle and the Ein Hamptonkam- mer a flow path is provided adjacent to the cup receptacle, that a pump is provided for the intermediate storage, for conveying the liquid Basic treatment means from the buffer to the flow path, that a purging device is provided for the cup receptacle, which serves for flushing the liquid treatment agent from the cup, wherein the adjacent to the flow path cup receptacle leads the purged liquid treatment agent to the flow path, and that Water inlet is provided, wherein in a flushing water from the water inlet via the chamber to the flow path can be guided.
  • the user may place a desired liquid base treatment agent as a container into the container receptacle, thereby allowing comfortable operation for the treatments frequently performed by the user.
  • an automatic program execution can advantageously be achieved by designing the pump as a metering pump in accordance with a program sequence. The effort for the user is thereby minimized.
