Abstract
In this household electrical steam generator, particularly for smoothing irons, the water level within the boiler is stabilized by electronic and/or pneumatic action, electronic action being actuated by a temperature sensor positioned on that portion of the body of a usual armoured resistance element which is subject to emergence following reduction in the water level, to activate a make-up micro-pump transferring into the boiler cold water drawn from a reservoir, pneumatic action being actuated by a floating valve enabling air to enter during boiler cooling, in order not to enable the boiler to draw water from the reservoir through the body of the halted micro-pump.
Claims20
A household electrical steam generator for supplying steam to an appliance, comprising:
- a reservoir for retaining water,
- a boiler for generating steam,
- first conduit means for interconnecting said reservoir and said boiler,
- pump means arranged in connection with said first conduit means for pumping water from said reservoir to said boiler,
- heating means arranged in said boiler for heating the water pumped from said reservoir to said boiler and converting the water into steam, said heating means comprising a resistor having a main portion lying in a substantially horizontal position in said boiler close to a bottom of said boiler, and an elevated region at a higher level relative to said bottom of said boiler and with respect to said main portion,
- second conduit means for connecting said boiler to the appliance,
- a valve arranged in connection with said second conduit means for regulating the flow of steam from said boiler to the appliance through said second conduit means, and
- regulating means for regulating a water level in said boiler during operation by activating and deactivating said pump means, said regulating means comprising sensing means in engagement with said elevated region of said resistor for sensing temperature in said boiler.
