Abstract (en)
The present invention relates to a washing machine with a perfected resin regenerating process which essentially provides for washing with any type of hard water. In the case of medium-high hard water, softened water may be used throughout the wash cycle. Provision is also made for using a two-way electrovalve with only two hydraulic. circuits. Finally, the extent to which the resins are regenerated varies according to the amount of water used in the wash cycle. These results are archieved by providing for more powerful resin regeneration with the aid of a first additional regenerating stage, in the case of a normal wash cycle, and of a second additional regenerating stage, in the case of an intensive wash cycle.
