An electric iron comprising a housing (1), a sole plate (2), a first reservoir (6) having an outlet (12) for a first fluid (7), an exchangeable reservoir (8) having an outlet (11) for a second fluid (9), which has a viscosity, and having coupling means (14), a nozzle means (10) comprising at least one aperture, a pump (19) for delivering a mixture of the first and second fluids to the nozzle means (10), said coupling means (14) comprising a first and a second inlet (15,16) and an outlet (17), said second inlet (16) of the coupling means being fixedly connected to the outlet (11) of the exchangeable reservoir (8), the first inlet (15) of the coupling means (14) and the outlet (17) of the coupling means (14) being connected to the outlet (12) of the first reservoir (6) and to a supply tube (18) to the pump (19), respectively, if the exchangeable reservoir (8) is inserted into the iron, at least one of the inlets (15,16) of the coupling means (14) and/or the outlet (11) of the exchangeable reservoir (8) being provided with a flow restriction (20,21) which is adapted to the viscosity of the second fluid (9) such that, given predetermined pumping characteristics of the pump (19), a predetermined desired flowrate of the mixture of fluids and/or a predetermined desired proportion of the first and second fluids (7,9) is obtained.
An electric iron comprising a housing, a sole plate, a first reservoir having an outlet for a first fluid, an exchangeable reservoir having an outlet for a second fluid, which has a viscosity, and having coupling means, a nozzle means comprising at least one aperture, a pump for delivering a mixture of the first and second fluids to the nozzle means, said coupling means comprising a first and a second inlet and an outlet, said second inlet of the coupling being fixedly connected to the outlet of the exchangeable reservoir, the first inlet of the coupling and the outlet of the coupling being connected to the outlet of the first reservoir and to a supply tube to the pump, respectively, if the exchangeable reservoir is inserted into the iron, at least one of the inlets of the coupling and/or the outlet of the exchangeable reservoir being provided with a flow restriction which is adapted to the viscosity of the second fluid such that, given predetermined pumping characteristics of the pump, a predetermined desired flowrate of the mixture of fluids and/or a predetermined desired proportion of the first and second fluids is obtained.
An iron as claimed in any one of the preceding claims, characterized in that the exchangeable reservoir is provided with a vent and the iron is provided with a valve for opening or closing the vent.
An iron as claimed in any one of the preceding claims, characterized in that the outlet of the coupling is provided with a filter.
An iron as claimed in any one of the preceding claims, characterized in that the coupling is integrated with the exchangeable reservoir.
An iron as claimed in anyone of the preceding claims, characterized in that the aperture(s) of the nozzle means are located in the sole plate.
An iron as claimed in any one of the preceding claims, characterized in that the second fluid is an additive fluid in concentrated form.
An exchangeable reservoir comprising a fluid and intended for use in the iron as claimed in any one of the preceding claims, characterized in that the reservoir is provided with a coupling which comprises a first inlet intended to be coupled to the outlet of the first reservoir, a second inlet fixedly connected to the outlet of the exchangeable reservoir, and an outlet intended to be coupled to the pump, and in that at least one of the inlets of the coupling is provided with a flow restriction.
