Such a concentration of steam flow on a small number of steam outlet holes, near the front tip of the flat surface, has the advantage of providing a powerful and accurate steam flow able to better target a particular area to unwind.

Such a construction therefore makes it possible, by a simple and economical solution to implement, to improve the performance of an apparatus for vertical steaming using a steam flow.

Indeed, the apparatus thus produced allows a fast and efficient treatment of clothing highly vapor permeable fabric when the button is not actuated, through the diffusion of steam by a large number of steam outlet holes covering a wide surface treatment. Conversely, when the user wishes to unwind a garment made in a low vapor permeable textile, requiring a greater speed of the steam flow, or when he wishes to precisely treat an area of the garment, it suffices to squeeze on the button to get more powerful steam jets on a small number of steam outlet holes.

We thus obtain a device whose versatility and efficiency in the treatment of clothing is improved.

Of course, the invention is not limited to the embodiment described and illustrated which has been given by way of example. Modifications are possible, particularly from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.

Thus, in a variant embodiment not shown, the closing of the steam flow towards the second group of steam outlet holes can be achieved by means of a pivotally mounted flap.

Thus, in another variant embodiment not shown, the surface receiving the steam outlet holes may be curved.

Thus, in an alternative embodiment not shown, the control button of the valve may be constituted by a circular wheel rotating around the handle.
