Benefits of technology

[0007]In the present invention, the Operator doesn't have to manually open and close a return valve, because a thermodynamic automatic discharging valve detects steam and condensate. When the thermodynamic automatic discharging valve is in contact with condensate, the valve permits the flow of condensate back to the boiler's return tank.
[0008]But when the Thermodynamic automatic discharging valve is in contact with pressurized steam, the valve traps the steam inside the iron, to prevent steam from being wasted by discharging back to the boiler's return tank.

Problems solved by technology

When the operator opens the valve, it emits, not only condensate, but also a huge amount of pressurized steam back to boiler.
If the operator doesn't open the valve often, condensates comes out through vents in the iron and may stain the fabrics being ironed.

Embodiment Construction

Conventional Iron

[0015]FIG. 1 shows a conventional steam powered iron 2c.

[0016]Steam is supplied by a boiler through a steam hose, to a steam connection 4. Steam collects in a steam chamber inside body 5, and heats the iron 2c. Lever 8 is depressed by thumbpad 9 to actuate steam discharge valve 10. This discharges the steam, under its steam pressure through a plenum to a plurality of vents 12 (FIG. 2) in bottom 14 of the iron, applying steam to the garment being pressed. As long as the steam is liberally discharged, the iron 2c remains hot and full of steam. But if the iron 2c sits idle for a while, heat is lost to the atmosphere, and the steam, giving up its heat of vaporization, condenses.

[0017]It is not desirable to wet the garment with liquid water, when the steam is discharged. So the condensate should be purged. Manual turn valve 16 is therefore opened by the operator, to discharge the condensate through a condensate connector through a second hose, a condensate return hose, ...

Abstract

An improvement in a steam powered pressing iron, in which steam is supplied by a boiler. The steam collects in a steam chamber inside a body 5, and heats the iron. A lever 8 is depressed by a thumbpad 9 to actuate a steam discharge valve 10. The steam discharge valve 10 discharges the steam to a garment being pressed. The improvement includes a steam trap valve 36. The steam trap valve discharges condensate to a discharge return connector 38, through the return hose to the boiler. The steam trap valve 36 is a thermodynamic steam trap, for preventing the flow of hot steam back to the boiler. But when in contact with cold condensate, the steam trap valve 36 automatically permits the flow of condensate back to the boiler. Cold condensate is automatically purged from the iron without operator intervention.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application is a Non-provisional application taking benefit and priority of U.S. Provisional Application 61 / 408,331, filed Oct. 29, 2010.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The Present invention relates to an improvement in a commercial steam powered pressing iron, as is typically used by dry cleaners, and commercial pressing operations.[0004]2. Related Art[0005]Prior art is shown in FIG. 1. In using a conventional steam iron, the Operator must manually open an exhaust valve to get rid of condensate, and close the exhaust valve to block steam, to prevent wasting steam. When the operator opens the valve, it emits, not only condensate, but also a huge amount of pressurized steam back to boiler.[0006]If the operator doesn't open the valve often, condensates comes out through vents in the iron and may stain the fabrics being ironed.BRIEF DESCRIPTION OF THE PRESENT INVENTION[0007]In the present invention, the Op...
