Definitions

  • Steam iron is equipped with second steam-generating chamber capable of generating a blast of steam which is communicated to steam channel at toe of iron to focus blast for better directing by housewife, Unplug gable vents at rear end of steam channel permit flushing of lint and dirt out heel of iron to keep them off sole plate ironing surface.
  • This invention relates to an electric steam iron. More specifically, this invention relates to an electric steam iron having a conventional steam supply and also means for supplying to the sole plate a quantity of steam substantially greater in rate but of shorter duration than the steam supplied conventionally. In a preferred embodiment, the invention also includes means to use such a blast to clean the iron.
  • the steam from the auxiliary or second-generating chamber has blended with the steam from the primary steamgenerating chamber and has travelled through passages to be delivered to the steam-distributing channels at a position towards theheel of the sole plate.
  • the blast in its path toward the ports in the sole plate has passed by or near the' inlet of water to the primary steamgenerating chamber, there has been a forcing of such steam up through the supply nozzle to the primary steam-generating chamber, reducing the amount of steam that has reached the ports of the sole plate. It has, in addition, caused distracting gurgling sounds.
  • the piror art has also included a number of provisions for cleaning of the steam distribution channels and passageways in the sole plate.
  • One such provision for instance, has involved opening a large valve in the water tank to flush the remaining water at the end of the ironing operation into the sole plate generating chambers and consequently exploding steam through the various ports and channels for cleaning purposes.
  • means are provided for delivering the steam from the second steam-generating chamber to the steam-distributing channels at a position adjacent the toe of the iron. This means that the full force of such steam is focused generally adjacent the front end of the iron so that the housewife is able better to direct such steam at the desired spot on the garment beingpressed. Additionally, because such de' livery means does not involve a blending of second chamber flow with flow from the primary steamgenerating chamber, there is no tendency for the blast of steam to enter through the primary chamber nozzle into the water tank under usual ironing conditions.
  • openings are provided adjacent the heel of the iron from the steam distribution channels which openings are normally plugged but which, at the end of the ironing session, may be unplugged to permit the egress of the blast of steam to effect the harmless discharge of foreign material in the steam distribution channels with the result that such discharge will not find its way to the bottom of the sole plate.
  • openings when the plugs are removed, permit the insertion of a cleaning tool such as a brush when desired or necessary.
  • FIG. 1 is a centerline sectional view of an iron embodying the invention
  • FIG. 2 is a fragmentary, greatly enlarged view of the top of the sole plate cover surrounding the water supply nozzle to the primary chamber;
  • FIG. 3 is a sectional view taken on the line 3-3 of FIG. 2;
  • FIG. 4 is a fragmentary bottom plan view of the heel of the iron showing the plug means for the cleaning ports;
  • FIG. 5 is a sectional view taken on the line 5-5 of FIG. 4;
  • FIG. 6 is a sectional view taken on the line 66 of FIG. 4;
  • FIG. 7 is a top plan view of the sole plate and cover but without the plug retaining means or plugs;
  • FIG. 8 is a top plan view of the sole plate uncovered; and FIG. 9 is a sectional view on the line 9-9 of FIG. 8.
  • an electric steam iron embodying the invention is generally designated 10 in FIG. 1. It includes a sole plate 12 having a cover 14 and conventional thermostat means 16. Mounted above the cover is a water tank 18 over which is secured a conventional skirt 20.
  • a handle 22 which includes thermostat control and steady steam control means 24 and pump control 26.
  • a pump 28 is secured within the handle housing to the pump control 26 and serves, depending on the setting of control 30, to pump water from the tank 18 either to the spray 32 or through tube 33 (FIG. 7) to the second steam-generating chamber 54 (FIG. 8).
  • the means by which control 30 operates is not shown.
  • a U- shaped heating element 34 is embedded in the sole plate and is delivered electricity through a cord, not
  • a primary water outlet 36 extends downwardly from the bottom of the tank 18 and is aligned with an opening 37 in cover 14, as shown in FIG. 1.
  • a needle valve as is conventional, is raised and lowered by the control 24 to block or permit flow drip-by-drip into the first steam-generating chamber 38 (FIG. 8).
  • Chamber 38 has, extending rearwardly from it, a pair of fairly straight passages 40 which overlie the U-shaped heating element 34 (FIG. 8).
  • Disposed on the outside of the passages 40 is the deep steam distributing channel 44 which is also U-shaped. Deep slots 46 are disposed inwardly of the passages 40 and slots 48 and 50 communicate steam from the passages 40 to the deep channels 44 and 46 respectively. Channels 44 and 46 carry ports to deliver steam to the bottom of the iron.
  • a second steam-generating chamber 54 is disposedin the sole plate adjacent the U-shaped heating element and a labyrinth or maze 56 extends therefrom forwardly.
  • the cover 14 is secured to the sole plate by bolts, as shown.
  • the cover as shown in FIG. 2, is formed in the area surrounding the outlet 36 with an annular upwardly stamped hump 58 to provide an annular recess 60 (FIG. 3).
  • the recess is provided with an annular cover plate 62 which, as shown in FIG. 2, carries two apertures 64 and 66.
  • the seal of the cover plate to the margins of the recess is assured by a tight press fit. Sealants may be used.
  • the openings 66 and 64 are projected downwardly (FIG. 8) in dotted lines to show that they overlie the front of the maze 56 and channel 44 adjacent to the toe'of the iron.
  • steam generated in the second steam-generating chamber 54 flows through the maze 56, through hole 64 annular passage 60, and through the opening 66 and into channel 44 at the toe of the iron.
  • means are provided to clean the deep channels 44 using the steam generated in the second steam-generating chamber 54.
  • These means include the generally horizontal ports 68 (FIG. 8) which extend through the rear wall of the sole plate and communicate from the rear ends of the channel 44 to the outside of the iron.
  • the horizontal ports are of ample dimension, greater in diameter than the ports from the channel 44 to the bottom surface of the sole plate, for instance.
  • Plug means are provided for the ports 68. As shown in FIGS. 4 and 5, they preferably comprise mushroomshaped metal elements 70, the domes of which rest against the outer openings of the ports 68 respectively. Each of the plugs is secured by a spring wire element 72 which is fastened at its center at the rear of the iron almost on a centerline thereof. As shown, the stamped sheet metal shelf 74 has integral hangers bolted to the sole plate as at 76. The spring wire is deformed upward through notches in the shelf and a stamped tongue 78 is crimped inwardly over the center of the wire. The spring wire is prestressed to keep a compressive force holding the plugs 70 against the openings of the ports 68 respectively. As shown in the left-hand side of FIG. 4, to open the ports the plugs may be pulled rearwardly and deflected downward.
  • the ports 68 also allow access to the channels 44 for insertion of a tool, such as a brush, to remove lint therefrom.
  • An electric steam iron having independent steamgenerating systems comprising:
  • a sole plate having a U-shaped heating element embedded therein, a first steam-generating chamber adapted to receive water from a tank disposed in the iron, a deep U-shaped channel in the sole plate on the outside of the U-shaped heater and steam ports extending from the U-shaped channel to the undersurface of the sole plate, passageways disposed along the top of the U-shaped element connecting the first steam-generating chamber and the U-shaped channel adjacent the heel of the iron, and a second steam-generating chamber in the sole plate adapted to also receive water from a tank disposed in the iron;
  • cover plate means engaging the top surface of the sole plate to close off said chambers, passageway and channel, the cover plate means having conduit means adapted to connect the second steamgenerating chamber and the U-shaped channel at usually installed blocking the apertures respectively whereby the plug means may be removed to permit exit of steam from the passage to clean the channel.
