When the water in water pot 19 all has passed through described mixed zone 72, and mix with recovering liquid contained in mixed zone 72, there is the described anti-scale filter 15 of regeneration, say, that, described resin with which, can again take away from described pedestal 17 by described water pot.During actual regeneration step, need to continuing about 30 minutes, described water and the mixture of recovering liquid are discharged by described drain pipe 36.

Additionally, the period started at above-mentioned regenerative operation, user still can use ironing equipment 12, presses 22 press to use, and steam produced by contained remaining water in vaporizer 21 can be used to perform above-mentioned flatiron.

Described cylinder 28 is then taken away from described compartment 27, and can be dimensioned correctly described compartment 27.

Finally, described driving handle 35 is back to described first operating position, by making described driving handle 35 turn clockwise about 90 °, then will drive handle 35 towards described ironing equipment 12(Fig. 1, Fig. 3, Fig. 4 and Fig. 5) supporting construction 16 push hard.

After described water pot 19 is filled water and is placed on pedestal 17, it is possible to recover to press step normally.

It should be pointed out that, under the premise without departing from the field of the invention and scope, regeneration and/or some interpolations can be made for above-mentioned regenerating unit 10.

Such as, replace hand control mode, described distributing valve 33 and coupled tongue 35 to be controlled by by the device of a servo feed.
