An ironing machine to be used with an iron, comprising: - means for the production of steam; - a support surface for the iron; - an ironing board having a rear longitudinal end proximal to said support surface and a front end distal thereto, the ironing board having an ironing plane which extends along a longitudinal direction between said rear longitudinal end and said front end ( 21, 7) and has an upper support surface of the fabrics to be ironed, said ironing board having a box-shaped structure with a side wall closed at the bottom by a bottom wall and above by said ironing plane to define a steam collection chamber, wherein said upper support surface of said ironing plane is at least partially open to allow steam to outcome upwards and therefore towards the fabric to be ironed placed thereon; wherein said upper support surface has a mesh structure which extends over the whole longitudinal extension of said ironing plane to allow the steam to flow upwards and to favour the fall of a condensate in said collection chamber; characterized in that said steam production means comprise a boiler for the production of steam and a steam supply circuit connected thereto having at least one emission head of one or more steam jets, the latter being housed in said steam collection chamber, said jet emission head comprising a hollow bar fluidically connected to a steam delivery channel of said circuit and arranged transversely in said steam collection chamber, said bar being placed at the rear longitudinal end of said ironing board and being provided with a plurality of nozzles or emission holes of respective jets, in such a manner to achieve uniform vaporization of said ironing plane. - means for the production of steam; - a support surface for the iron; - an ironing board having a rear longitudinal end proximal to said support surface and a front end distal thereto, the ironing board having an ironing plane which extends along a longitudinal direction between said rear longitudinal end and said front end ( 21, 7) and has an upper support surface of the fabrics to be ironed, said ironing board having a box-shaped structure with a side wall closed at the bottom by a bottom wall and above by said ironing plane to define a steam collection chamber, wherein said upper support surface of said ironing plane is at least partially open to allow steam to outcome upwards and therefore towards the fabric to be ironed placed thereon; wherein said upper support surface has a mesh structure which extends over the whole longitudinal extension of said ironing plane to allow the steam to flow upwards and to favour the fall of a condensate in said collection chamber; characterized in that said steam production means comprise a boiler for the production of steam and a steam supply circuit connected thereto having at least one emission head of one or more steam jets, the latter being housed in said steam collection chamber, said jet emission head comprising a hollow bar fluidically connected to a steam delivery channel of said circuit and arranged transversely in said steam collection chamber, said bar being placed at the rear longitudinal end of said ironing board and being provided with a plurality of nozzles or emission holes of respective jets, in such a manner to achieve uniform vaporization of said ironing plane.
