DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to irons which comprise a sole extending longitudinally from a tip toward a heel and comprising a heating base and an ironing plate mounted below said base.
It relates more particularly to irons which comprise two independent steam chambers provided in the base enclosed by a cover, namely a first principal steam chamber supplied with water by means of a first injection device through a first opening provided in the cover and communicating, by means of steam distribution openings through the lower surface of the base, with first steam outlets in the plate and communicating with said steam distribution openings, and a second steam chamber disposed before said first chamber, supplied with water by means of a second injection device through a second opening provided in the cover and communicating, by means of at least one through passage opening on the lower surface of the plate, with a steam distribution chamber provided in the lower surface of said base and communicating with second steam outlets in the plate.
BACKGROUND OF THE INVENTION
It is known that such irons with two independent steam chambers, of which the first so-called principal chamber is a chamber for the production of continuous jets of steam at low pressure and of which the second is a chamber for the production of steam jets at higher pressure and with penetrating force, are particularly effective to respond to the various characteristics of the cloth to be pressed.
In known steam irons of this type, the steam distribution chamber provided in the lower surface of the heating base, and correspondingly the corresponding steam outlet holes at high pressure and high penetration, are generally disposed roughly in the midportion of the sole. Such an arrangement of these steam outlets is completely satisfactory as to pressing quality, but nevertheless, it is relatively poorly adapted for the comfort of the user while pressing when the latter must carefully carry out the marking of the creases in thick cloth, for example shirt folds.
The invention particularly has for its object to overcome this drawback and to provide in a simple way a steam iron, of the type described above, whose sole gives the user better pressing conditions whilst ensuring high quality of pressing no matter what the characteristics of the cloth to be pressed.
SUMMARY OF THE INVENTION
According to the invention, a steam distribution chamber extends in a region located in the tip of the heating base of the sole, and the second steam outlets communicating with said steam distribution chamber are arranged in the tip of the sole plate.
Thus, thanks to this particular arrangement of the steam outlets at high pressure and strong penetration, the diffusion of the steam is concentrated at the very point of the sole, and hence the comfort of the user while pressing, particularly to mark the creases in cloth, is particularly improved because it suffices for the user to "follow" the tip of the sole, which can be considered the dynamic guide point, thereby correctly to direct the iron along the fold to be marked, permitting the user thus to carry out carefully and with considerable ease this operation of marking the folds of the cloth.
In a particular embodiment, the second steam outlets define together a steaming area of approximately triangular shape whose summit is located immediately adjacent the summit of the tip of the sole plate.
BRIEF DESCRIPTION OF THE DRAWINGS
The characteristics and advantages of the invention will become further apparent from the description which follows, by way of non-limiting example, with reference to the accompanying drawings, in which:
FIG. 1 is a transverse cross-sectional view of a sole closed by a cover of a steam iron according to the invention;
FIG. 2 is a plan view of a heating base of the sole of FIG. 1, the cover being omitted;
FIG. 3 is a bottom plan view of this heating base; and
FIG. 4 is a plan view of the external surface of a pressing plate of the sole of FIG. 1.
