  • the present invention relates to a washing machine having an improved detergent feeding device.
  • washing machine users increasingly prefer to use liquid treatment agents, such as detergents and fabric softeners, for washing their laundry. Users are also encouraged to use liquid treatment agents as these are more environmentally friendly.
  • liquid treatment agents such as detergents and fabric softeners
  • Washing machines having systems for providing doses of liquid treatment agents are currently available on the market. These systems typically comprise tanks containing liquid treatment devices, a user interface to allow users to fill these tanks (such as drawers, lids, etc.) and a hydraulic device to transfer the correct amount of treatment agent to the washing area (laundry drum) at the correct time.

  • Some of the most important features of a dosing system are control of dosage amount, dosage tim ing, washing of dosage area by water to transfer the treatment agent to the laundry drum and detection of the fullness of the storage tanks.
  • the dosage system requires power in order to function and provide controlled dosing. Generally the required power is provided by the washing machine; therefore it is not possible to take the dosage system which is positioned inside the treatment agent storage out of the washing machine. For this reason, it is not possible to clean the treatment agent storage reservoirs of integrated systems.
