  • Patent number: 4658520
    Abstract: An electrically heated steam iron has a soleplate in which are arranged an electrical heating element and a vaporization chamber, and a soleplate liner which consists of a different material from the soleplate and which is fixed thereto. The soleplate is provided with steam escape holes which communicate with respective openings in the soleplate liner, each such opening having a steam distribution groove on the ironing surface of the soleplate liner. The soleplate has recesses each congruent to a respective steam distribution groove and the longitudinal axes of all the grooves are directed towards the center of gravity of the ironing surface of the soleplate liner.

  • Patent number: 4586277
    Abstract: A steam iron has a water storage tank, an evaporation chamber to provide steam for ironing, and a drip valve for regulating the flow of water from the tank into the evaporation chamber. A pressure chamber in the tank is connected to the evaporation chamber via a pressure equalization passage. The pressure chamber is also connected to receive water from the tank via a non-return valve and is connected to feed water to said evaporation chamber via said drip valve.

  • Patent number: 4567679
    Abstract: An electrically heated steam iron operable by a drip system includes a drip valve arranged to have a variable rate of flow of water therethrough, and a water tank the interior of which is vertically divided into two chambers and by a partition wall, the two chambers being in flow communication with each other via an opening. A vaporizing chamber is disposed below the drip valve. A vertically adjustable slide member is arranged to slide relative to the partition wall while being sealingly engaged therewith, and adjustment means comprising a valve rod is connected to the slide member. The valve rod passes through a top surface of the tank, wherein vertical adjustment of said slide member by means of the valve rod is effective to vary the height of the column of water above the drip valve, thereby adjusting the rate of flow of water.

  • Patent number: 4347428
    Abstract: An electronic temperature control circuit for regulating the soleplate temperature of an electrically heated pressing iron is located in the handle and supporting structure of the iron. The electronic circuit includes a thyristor controlling energization of the soleplate heater and tending to emit heat. The thyristor is mounted to a heat dissipating cooling plate located within a leakproof cavity in the supporting structure remotely from the other electronic components of the control circuit tending to be adversely affected by heat. The cooling plate and thyristor are mounted on a detachable wall closing the cavity and shaped to provide a resting stand which allows the iron to be rested flatly on a horizontal surface without the soleplate contacting the surface.
