Example Embodiment

[0023] in figure 1 In the first embodiment shown, the iron includes a housing 1 with a bottom plate 2 which is heated by an electric heating element 3. The foam is produced by the nozzle unit 4, its work will be referred to below figure 2 Description. The iron includes a tank 5 containing a foaming liquid 6 under pressure. The storage tank 5 may be, for example, a detachable cassette. The foaming liquid contains a small amount of surfactant in order to reduce the surface tension. The concentration of surfactant must only be higher than the critical micelle concentration (CMC) in order to generate foam. In practice, this means that the concentration is about 0.2 to 0.5 weight percent. The storage tank 5 has an outlet 7 connected to the first inlet 8 of the nozzle unit 4 through a duct 9. If necessary, the flow rate of the foaming liquid from the storage tank to the nozzle unit can be adjusted. The iron also includes an electric air pump 10, the outlet 11 of which is connected to ...

Abstract

The invention relates to an iron having means for moistening fabric to be ironed. According to the invention, the moistening means comprise a device for generating foam and means for applying said generated foam to the fabric. For example, foam may be generated by means of a nozzle ( 21 ) having a first inlet ( 8 ) for a foaming liquid ( 6 ) and a second inlet ( 12 ) for supplying pressurized air to the nozzle so as to mix air with said liquid, thereby creating foam ( 42 ). Applying foam to the fabric ( 50 ) can be realized by means of a doctor blade ( 51 ) to break up the foam.

Description

technical field [0001] The invention relates to an iron having a soleplate, means for heating said soleplate and means for moistening fabrics to be ironed. Background technique [0002] To improve ironing results, it is generally known to moisten fabrics prior to ironing. Wetting can be accomplished, for example, by spraying water on the fabric. The fabric will absorb the water and wet the fabric after a while. Water is sprayed from a separate container or from a spray device provided on the iron. How evenly the fabric is wetted depends on the skill of the user. Typically, fabrics do not appear to be evenly wetted. Another way of wetting fabrics is by steam. Steam irons are well known. During ironing, steam penetrates into the fabric, making creases easier to remove during subsequent ironing actions. This mode of wetting is more convenient for the user, but the wetting itself is not very satisfactory. Due to the high temperature of the fabric (often at 100°C), the wa...
