Patent number: 8256149Abstract: The invention relates to an ironing shoe (10) comprising a garment contact surface (15) and having a means for accommodating a garment care agent such as an anti microbial agent, wherein accommodating the means is formed at least by the garment contact surface accommodating the garment care agent, which garment contact surface is capable of transferring the garment care agent to a piece of garment. By contacting the garment contact surface with the piece of garment, as is done during ironing, the agent is transferred to the garment. The invention further relates to a method of manufacturing an ironing shoe.Type: GrantFiled: October 2, 2007Date of Patent: September 4, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Vignesh Nathamuni Balaji, Yong Jiang, Pieter Johannes Werkman, Maarten Van Den Boogaard

Patent number: 8181369Abstract: The invention relates to an iron (1) comprising a soleplate (3) having a garment-contact surface (5) and having a means for accommodating an antimicrobial agent. By contacting the garment-contact surface with the piece of garment, as is being done during ironing, the antibacterial agent is transferred to the garment. The antimicrobial agent is disposed on the garment by simply placing the iron on the garment and moving it over the garment surface. The garment stays fresher for a longer period of time. The invention further relates to a soleplate, a steam ironing device and methods of manufacturing an iron and a soleplate, respectively.Type: GrantFiled: October 2, 2007Date of Patent: May 22, 2012Assignee: Koninklijke Philips Electronics N.V.Inventors: Vignesh Nathamuni Balaji, Yong Jiang, Pieter Johannes Werkman, Maarten Van Den Boogaard

Patent number: 7690140Abstract: An ironing shoe comprising a laminate having at least one laminate opening and a laminate periphery similar to a sole periphery of a sole plate of an iron, the sole plate having a sole plate surface, the laminate comprising a heat insulating layer having a sole contact surface for making contact with the sole plate surface of the iron and a heat transfer layer having a garment contact surface for ironing. The shoe can comprise a fastening means in the form of a protrusion, the protrusion and the heat insulating layer being made of the same material. The heat insulating layer can have an edge rib alone at least a part of its periphery to reduce the leakage of steam.Type: GrantFiled: February 22, 2007Date of Patent: April 6, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Kat Tong Ho, Pieter Johannes Werkman, Li Chen Tan, Saskia Ingeborg Kranenberg

Patent number: 7663075Abstract: Disclosed is a layer for use in a domestic appliance, based on a sol-gel precursor. This layer can be obtained by screen-printing and comprises an organosilane compound. The layer is obtained from a concentrated pre-polymerized sol-gel precursor. The layer can be used as an insulating layer or as a conductive layer in a heating element. Furthermore, the layer can be used for decorative purposes.Type: GrantFiled: May 13, 2005Date of Patent: February 16, 2010Assignee: Koninklijke Philips Electronics N.V.Inventors: Poh Loo Lee, Gerard Cnossen, Marcel Rene Boehmer, Sandor Nemeth, Pieter Johannes Werkman

Publication number: 20080313936Abstract: An ironing shoe (202) comprising a laminate (204) having at least one laminate opening (215) and a laminate periphery similar to a sole periphery of a sole plate (203) of an iron (201), the sole plate having a sole plate surface (210), the laminate comprising a heat insulating layer (205) having a sole contact surface (206) for making contact with the sole plate surface of the iron and a heat transfer layer (207) having a garment contact surface (208) for ironing. After mounting the ironing shoe according to the invention to the iron, the sole contact surface of the heat insulating layer is in contact with the sole plate surface of the iron. The sole contact surface and the garment contact surface of the heat transfer layer are turned away from each other. During mounting and unmounting of the shoe, as well as during ironing, the garment contact surface of the heat transfer layer is not in direct contact with the sole plate.Type: ApplicationFiled: February 22, 2007Publication date: December 25, 2008Inventors: Kat Tong Ho, Pieter Johannes Werkman, Li Chen Tan, Saskia Ingeborg Kranenburg
