An electric steam iron comprises a pump (20) adapted to remove a quantity of water from a reservoir (17) and to send this quantity, via a selection device (24), either into a steam chamber (14) so as to obtain abruptly an abundant emission of steam through holes in the sole, or to a cold water spray
An electric steam iron comprises a pump (20) adapted to remove a quantity of water from a reservoir (17) and to send this quantity, via a selection device (24), either into a steam chamber (14) so as to obtain abruptly an abundant emission of steam through holes in the sole, or to a cold water spray (25), this pump being of the type having a piston (27) movable in an intake chamber (31). The selection device comprises a deformable membrane (56) with two valves (58, 59) associated respectively with two openings, namely an injection opening (44) connected to the steam chamber (14) and a spray opening (45) connected to the spray chamber (25) and subjected respectively to two manual control buttons, namely, a steam button (62) and a spray button (63). The membrane (56) occupies a working position, defined when one or the other of the two buttons (62, 63) is actuated, in which the valve associated with the actuated button is maintained closed and obstructs the corresponding opening, while the valve associated with the other button opens by deformation of the membrane (56) effected by pressure of the pressurized water and clears the corresponding opening through which passes the pressurized water.

In a steam iron comprising a heating sole (11) having in its lower surface a series of steam outlet openings (12) and in its upper surface a vaporization chamber (14) connected with said holes (12) and communicating with a water reservoir (17), and a pump (20) adapted to remove from said reservoir (
In a steam iron comprising a heating sole (11) having in its lower surface a series of steam outlet openings (12) and in its upper surface a vaporization chamber (14) connected with said holes (12) and communicating with a water reservoir (17), and a pump (20) adapted to remove from said reservoir (17) a quantity of water and to send this quantity via a selection device (24) either into said steam chamber (14) so as to obtain an abrupt abundant emission of steam through the holes (12) of the sole, or to a cold water spray (25) located in the forward portion of the iron, the pump (20) having a piston (27) moving in an intake chamber (31) which is provided in a body (21) of the pump and which opens into the reservoir (17) via a non-return valve (35); the improvement wherein the selection device (24) comprises a deformable membrane (56) having a substantially flat lower portion (56a) provided with two protuberances (58, 59) each serving as a valve and being maintained in place in a sealed manner in a cap (39) which is formed in an upper portion of the piston (27) of the pump and whose bottom (40) communicates with the intake chamber (31) through a pressurizing bore (42) provided in said piston and has two openings comprising an injection opening (44) connected to the vaporization chamber (14) and a spray opening (45) connected to the spray (25), the two valves (59, 58) of the membrane (56) being located respectively adjacent the two said openings (45, 44) and their operation being subjected respectively to two manual control buttons, respectively a vaporization button (62) and a spray button (63), which project from an upper portion of the iron and of which the steam button (62) is connected to the valve (59) associated with the spray opening (45), whilst the spray button (63) is connected with the valve (58) associated with the injection opening (44), the membrane (56) passing from a rest position, defined when the pump (20) is primed, in which the two valves (58, 59) are closed and respectively obstruct the two openings (44, 45), to a working position, defined when one or the other of the two buttons (62, 63) is actuated, in which the valve (58; 59) associated with the actuated button (63; 62) is maintained closed by said button and obstructs the corresponding opening (45; 44), whilst the valve (58; 59) associated with the other button opens by deformation of the membrane (56) effected by the pressure of the pressurized water through the bore (42) of the piston and frees the corresponding opening (44; 45) through which passes the pressurized water.
