The number of controls on the surface of Ironing device remains limited, so the user does not have another control to trigger the rinse function can be irritated. Because the means for rinsing separately from the dripping device designed, it can be carried out with greater freedom of design, both in terms of the size of the opening, through the water passes through and the distance between the dripping device and flushing device. By causing the water, which is the rinsing of the steam chamber for limescale removal enter the steam chamber at a different location than the water, which enters the chamber for steam generation, it is possible to have a bigger amount for rinsing to bring into the chamber and thus the flushing of the chamber more effectively to design.

It has proven to be advantageous when the separate means for do the washing up includes a spring. It has proved to be particularly advantageous proven when a closure of the separate means for rinsing over the Spring takes place, and / or a return of the Means for rinsing from an open one in a closed state over the spring executable is. This will ensure that in the regular Ironing operation the separate means reliably closes and enters accidental ingress of water is avoided.

at the same time ensures that after completion of the rinse function the separate means also reliable again closes.

It has also proved to be advantageous if the valve rod can be raised via a wheel-shaped actuating part. As a result, the operation of the flushing function can be integrated in a simple manner in the regulation of the steam function. This allows the user to initiate the flushing function with a simple operation of the wheel-shaped actuating part. It can also with an actuation of the Radförmigen control the flushing function are completed again.

It has proven to be advantageous when the electrical device for ironing has a clue indicating the user when the implementation a rinse function is required. This can be ensured that the Users a reliable Information gets when the implementation a washing program is required. damage the ironing device are thus effectively avoided.

From It is particularly advantageous if the instruction to the user, that an implementation a rinse function is required, optically and / or acoustically. This can z. B. over a signal lamp, which may be an LED light for the purpose of energy saving, done or over a characteristic beep.

From It is particularly advantageous if the determination of when a rinse function is required, depending a measured time span and / or measured technical parameters the device takes place. This can be z. B. be done by that the device for ironing has a means for determining the operating time, and after expiration a defined operating time, z. B. after 100 hours of operation, the User informs that performing a purge function is required. Determining if performing a purge function is required, but can also be particularly advantageous depending of measured technical parameters. This means that the device for ironing technical values parameters that exist in the presence of a lime scale change, z. As the electrical conductivity or the thermal conductivity.

In a preferred embodiment has the device for ironing an electrically operated pump, by means of which the rinsing function amplifiable is. This makes it possible the rinse function to run faster and more effectively. It can the Electrically operated pump through the water even at intervals rinse the steam chamber.

The present invention enables in a device for ironing in more effective and cheaper Way a rinse function for the removal of calcifications.
