Abstract
A household appliance for steam generation with a boiler containing a heating source for water vaporization intended to be partly immersed in water; a control means for adjusting the pressure valve of the steam in the boiler that operatively associated with the heating source to switch on or off so as to maintain the steam pressure at a desired value; and a steam delivering means. The means for adjusting the pressure value in the boiler is operatively associated with the steam delivery means so as to switch the heating source on and off in function of the open or closed status of the steam delivery means.
Claims16
A household appliance (100) for steam generation, comprising
- a boiler (5) comprising, in turn, a heating source (7) for water vaporisation intended to be at least partly immersed in water,
- control means (13) comprising, in turn, means (30) for adjusting the pressure value of the steam in the boiler (5) , said means (30) being operatively associated with the heating source (7) to switch it on/off so as to maintain the steam pressure at a desired value,
- steam delivering means (9, 10),
- characterized in that the means (30) for adjusting the pressure value in the boiler (5) is operatively associated with the steam delivery means (9, 10) so as to switch the heating source (7) on/off in function of the open/closed status of the steam delivery means (9, 10).
The method for adjusting the steam pressure in a boiler (5) comprising a heating source (7) intended to be at least partly immersed in water for water vaporisation, said boiler (5) being associated with steam delivery means (9, 10), said method comprising the steps of
- a) powering the heating source (7) at the switching of the appliance (100);
- b) switching the heating source (7) on/off so as to maintain the steam pressure in the boiler (5) at the desired value, characterised in that it also comprises the step c) of checking the open/closed status of the steam delivery means (9, 10), and in that step b) is carried out in function of the open/closed status detected in step c).
