  • Publication number: 20020002782
    Abstract: A water reservoir for a clothes pressing iron, the reservoir being composed of two plastic parts, and a method for fabricating the reservoir by: simultaneously molding the two parts of one reservoir in a first injection molding step in two impressions of the same mold; and assembling the two parts together while, in a second injection molding step, injection molding a joint of plastic material between the two parts to connect the two parts together in a fluid-tight manner, wherein the two parts are assembled together and the second injection molding step is performed before complete crystallization of the two parts.

  • Patent number: 6035563
    Abstract: An electric iron has a soleplate with a front tip and at least one passage for a liquid stored in a liquid tank system for wetting an article to be ironed. The passage is arranged in the area of the front tip symmetrically to a central line which starting from the front tip divides the soleplate in the middle. The liquid exits the passage in the form of liquid droplets generated by a piezoelectrically driven sprayer arranged above the soleplate. The electric iron is characterized in that the sprayer (12, 13, 14, 29) has at least one piezoelectrically driven thin membrane plate (12) with a plurality of spraying holes (24) associated with the respective passage (11) of the soleplate (6) and having a mean clear width from 30 to 100 .mu.m. The number of spraying holes (24) is selected to ensure that the amount of liquid dispensed through the soleplate (6) does not exceed about 8 g/minute. The passages (11) are maximum 10 mm wide, whatever their length.
