Definitions

  • This invention relates to steam irons and more particularly t the form of steam iron employed for household use.
  • the small size of the boiler was not the only cause of the irons running out of water.
  • the construction of such irons was at fault also, since it permitted water and steam to be discharged in an inefficient and uneconomical manner.
  • the smallness of the boiler would be desirable if some construction could be devised for efiiciently dampening the material to be pressed with a smaller volume of water.
  • Such construction is provided by the steam iron of my invention, as will be pointed out hereinafter.
  • the steam iron of my invention may, therefore, be used withno more tiring effect than would be occasioned with an ordinary iron which lacks the steam feature.
  • my iron is very economical in its use of water, and yet provides proper and uniform dampening of the materials to be pressed. This means that the user may employ the steam iron of my invention for extended periods of time before a refilling of the boiler is required. Although some materials may require sprinkling or dampening in addition to the steam, that is true when any steam iron is used.
  • I provide a structure within the iron which traps slugs of water or condensate, and, in addition, converts the water to steam.
  • the structure includes a chamber which atomizes the water trapped therein and serves to convert the water into steam and the steam into superheated steam. In this form the steam is very much thinner and may be dispersed a greater distance over the material before it returns to its liquid state.
  • the atomizing feature may optionally be omitted, but in the embodiment herein disclosed, any condensate in the superheater chamber, or any raw water that enters the chamber is tapped against exit from the superheater chamber, and is converted into steam before it is able to escape.
  • the chamber also serves as a metallic path for transmitting heat to the water in the boiler for converting it to steam.
