Definitions

  • the invention herein pertains to a steam flatiron of the flash steam type containing a thermally connected means to the soleplate which, conveniently, is an extension of the usual iron coverplate, to extend beyond the soleplate and provide a peripheral groove means around a smooth unbroken soleplate whereby a curtain of steam is directed peripherally about the entire soleplate or a selected part thereof.
  • any break in the soleplate ironing surface tends to create wrinkles and is subject to clogging from lint that is generated during the ironing process. Inserts with their necessary fasteners are further subject to uneven temperature gradients since they tend to be cold relative to the soleplate and must be heated by the steam very iIlCfficient. The temperature differences result in increased drag during operation. Also, inserts break the smooth continuity of the soleplate to provide catching and lintgenerating surfaces to subsequently reduce the steam rate of the iron. Still other irons have provided smooth ironing surfaces with means around the soleplate to ingest air and distribute it above the soleplate for temperature control purposes by introducing a cooling effect.
  • the invention is directed to any type steam flatiron with an integral continuous and smooth heated soleplate and having a steam generator formed in the soleplate.
  • a water tank is provided in the iron with the usual valve means to start and stop a metered flow of water from the tank through an orifice into the generator to control steam generation.
  • a means that may conveniently be the coverplate which is placed in intimate thermal connection with and overlying the soleplate to define steam passages between the soleplate and coverplate.
  • the coverplate is extended over the side of the soleplate substantially down to the ironing surface so that it fits the soleplate cup-like and extends along the periphery spaced therefrom to define peripheral steam groove means whereby steam exits the iron only along the periphery as a curtain of steam with the entire smooth soleplate available for ironing.
  • the steam groove may extend along both sides of the iron with the exclusion of the heel rest portion or may extend only partially depending on the extent of the steam curtain desired.
  • FIG. 1 is an elevational view of an iron, partially in section and broken away, showing general parts of an iron using the invention
  • FIG. 2 is a partial perspective broken view of an iron illustrating the internal arrangement of the soleplate and coverplate with the outer shell;
  • FIG. 3 is a bottom view of a typical soleplate using two forms of steam grooves.
  • FIG. 1 there is shown a typical steam flatiron of any suitable form such as shown in US. Pat. No. 3,605,299, of common assignment, and which includes soleplate 10 that, in the present invention, is an integral continuous and smooth soleplate uninterrupted by any usual steam discharge ports or, in effect, a soleplate of the type generally used with a dry iron as opposed to a steam flatiron.
  • soleplate 10 may be cast from a suitable material, such as aluminum, with an electrical heating element 12 cast in position.
  • the heating element 12 extends in a loop beginning at the rear of the iron and along one side to the forward end and then rearwardly along the other side.
  • substantially uniform heat distribution is provided when the iron is turned on and the general form described is wellknown.
  • the iron includes any suitable means for generating steam by providing water tank 14 therein.
  • the heated soleplate 10 has a flash steam generator 16 formed therein under control of an on-off water valve structure of known construction and including button 18 to control steam generation by starting and stopping a metered flow of water from the tank through an orifice 20 into the generator in the heated soleplate, the water flashing into steam which is usually distributed under coverplate 22 and normally out soleplate ports onto the fab- ['10.
  • the present invention provides coverplate 22 in intimate thermal connection with and overlying the soleplate 10 as shown in FIG. 1 to define the steam generator as well as steam passages 24 therebetween so that steam created in generator 16 passes under the coverplate 22 and into passages 24 in a generally known manner.'Normally such steam would be directed out soleplate ports but the present iron omits such ports. In lieu thereof, the iron provides a curtain of steam around the periphery of the soleplate. To this end, as seen in FIG.
  • the coverplate 22 is extended beyond the soleplate periphery and directed downwardly substantially to the ironing surface in a cup-like fashion around the periphery of the soleplate. This extension is spaced from the soleplate to define peripheral groove means 26 and the coverplate is suitably formed as seen in FIG. 2 to provide a connection between the steam passages 24 and groove means 26 whereby the steam exits only along the entire groove means.
  • the extended coverplate may be directed down to the surface of the soleplate to be coextensive therewith as shown or may end slightly above the surface.
  • the outer edge of the iron becomes a part of the soleplate around its edge and the finishing operation smoothing up the surface of the soleplate and the edge of the coverplate extension creates a surface which, when rounded as shown, provides no wrinkling or drag.
  • the edge of the iron is the most important surface since it does the flattening, removing of the wrinkles, and it is the edge the operator can see.
  • the rounded edge creates, in effect, an extension of the soleplate.
  • the curtain of steam or peripheral groove means may extend any substantial distance to cover completely two sides of the iron as shown on the right side of FIG. 3 or it may extend only partially as shown on the left side. Further, it normally will not extend across the heel portion 34 which is grooveless so that it may be used to rest the iron when not in use in conventional fashion. Thus, the groove may extend any length of the two sides and generally will cover a substantial portion as shown in FIG. 3.
  • the present invention provides a unique steam iron that redirects the steam as a curtain of even distribution around the peripheral edge of the iron where it can be seen and where the entire integral continuous smooth heated surface of the soleplate is available for ironing uninterrupted by any ports or recesses for efficient uniform heating, smoothly, low drag, and resultant easy ironing.
  • a steam flatiron having an integral continuous smooth heated soleplate with a steam generator formed therein, a water tank within the iron and means to start and stop a metered flow of water from said tank through an orifice into the generator to control steam generation,
  • said means extending substantially down to the ironing surface cup-like around said soleplate and along the periphery thereof and spaced from the soleplate to define peripheral groove means therewith,
