Abstract

An electric iron wherein a cermic sole plate transmits infrared light and is heated by one or more halogen lamps within a reflector in the housing of the iron whose concave surface faces the lamp or lamps and reflects heat upon the sole plate. The reflector further effects the heating of water which is admitted into a steam chamber in the housing of the iron between the reflector and the ceramic sole plate, and the resulting steam is conveyed to nozzles extending into openings in the sole plate.

Claims

1. An electric steam iron, comprising a hollow housing having an open bottom;

handle means provided on said housing for manipulating the iron;

a sole plate secured to and covering the open bottom of said housing and composed of a light transmitting ceramic material which absorbs part of the light passing through the sole plate;

means for heating said sole plate including a halogen lamp in said housing and in spaced relation to said sole plate and reflector means provided in said housing to reflect upon said sole plate light which is emitted by said lamp, the amount of light which is absorbed by the sole plate being sufficient to heat the sole plate to an ironing temperature, said housing further having a steam chamber which is disposed between said reflector means and said sole plate and is heated by radiant energy radiated by said lamp and/or reflected by said reflector means;

means for admitting water into said chamber; and

means for conveying steam from said chamber to a point of use.

2. The iron of claim 1, wherein said reflector means includes a portion having a concave surface facing said lamp and said sole plate.

3. The iron of claim 2, wherein said portion of said reflector means has a center of curvature at least close to said sole plate.

4. The iron of claim 1, wherein said sole plate has at least one opening and said conveying means comprises a steam discharging nozzle in the region of said opening and means for connecting said chamber with said nozzle.

5. The iron of claim 4, wherein said sole plate has a plurality of openings in a predetermined distribution and said conveying means comprises a nozzle in the region of each of said openings and means for connecting said chamber with said nozzles.

6. The iron of claim 1, further comprising at least one socket for said lamp in said housing.

7. The iron of claim 1, wherein said heating means comprises a plurality of halogen lamps.

8. An electric steam iron, comprising a hollow housing having an open bottom;

handle means provided on said housing for manipulating the iron;

a sole plate secured to and covering the open bottom of said housing and composed of a light transmitting ceramic material which absorbs part of the light passing through the sole plate;

means for heating the sole plate including a halogen lamp in said housing in spaced relation to said plate and reflector means provided in said housing to reflect upon said sole plate light which is emitted by said lamp, the amount of light which is absorbed by the sole plate being sufficient to heat the sole plate, said housing further having a steam chamber which is heated by radiant energy radiated by said lamp and/or reflected by said reflector means and said reflector means surrounding at least a portion of said chamber;

means for admitting water into said chamber; and

means for conveying steam from said chamber to a point of use on the iron.
