Abstract
The invention discloses a steam iron water valve structure for feeding water into a steam generating chamber. The valve structure adapts the iron for use with any reasonable tap water available by using a scraping or cleaning arrangement of the various orifice and valve structure to remove deposits on each operation and to reduce the vertical extent of the valve travel.
Claims5
In a steam iron having a water tank, steam generating soleplate, a guided water valve with a stem and metering rod portion movable between an on-off position and an outlet duct from the tank having a recess and extending below said valve directing water to the soleplate for steam generation, the improvement comprising:
- a thin stainless steel sheet metal cup-shaped plate with a flanged rim overlying the duct and an upwardly-domed bottom with an orifice in the dome;
- said flange fixedly nesting the plate in the duct above the recess bottom;
- a separate floating centrally-apertured thin stainless steel scraper plate in the recess below the cup-shaped plate;
- said metering rod portion carried by the stem and having dual diameters with the rod continuously protruding through said orifice;
- the small diameter adapted to scrape in the plate aperture and large diameter scraping the orifice;
- the distance between orifice and scraper plate being less than the total valve travel so both orifice and small diameter are simultaneously scraped on each valve operation and a scraped rod is always disposed in a scraped orifice in valve-on position for continuous accurate control.
