Definitions

  • the invention relates to an ironing shoe for garment care device.
  • the invention has some applications in the field of garment care.
  • Ironing shoe (sometimes also called “fabric protector”) is a known accessory intended to cooperate with a garment care device having a soleplate, such as a steam iron.
  • the goal of an ironing shoe is to reduce the heat transfer between the soleplate and the garment being treated (e.g. ironed).
  • the treatment of the garment is thus done by the ironing shoe with a temperature much lower than the temperature of the soleplate.
  • Known ironing shoes comprise a plate, for example made of aluminium, in which steam holes are arranged, the plate having an outside face intended to come into contact with garments to be treated by the garment care device, and an inside face covered by silicone rubber which faces the soleplate when the ironing shoe is attached to the garment care device.
  • the silicone rubber reduces the heat transfer.
  • an ironing shoe adapted to be removably attached to a soleplate of a garment care device, the ironing shoe comprising a plate, the plate comprising an outside face intended to come into contact with garments to be treated and an inside face intended to face the soleplate when the ironing shoe is attached to the garment care device, the inside face comprising:
  • the heat insulating layer allows reducing the heat transfer between the soleplate and the plate of the ironing shoe.
  • the air gap created between the heat insulating layer and the soleplate when the ironing shoe is attached to the garment care device further reduces the heat transfer between the soleplate and the plate of the ironing shoe.
  • the heat conductive protruding structure allows conducting locally a limited amount of heat from the soleplate to the plate of the ironing shoe. As a consequence, when the ironing shoe is attached to the soleplate, the plate of the ironing shoe is able to increase in temperature much faster. In this situation, after the ironing shoe has been attached to the soleplate, if the user starts steam-ironing, the condensation of steam on the ironing shoe will be greatly reduced. In other words, the heat conductive protruding structure solves the problem known as "spitting".
  • the heat conductive protruding structure has a top part defining a contact area with the soleplate.
  • the ratio between the surface of said contact area and the surface of the inside face is in the range [0.5; 30.0] %.
  • Such a range allows conducting locally and quickly a limited amount of heat from the soleplate to the plate of the ironing shoe, which is helpful to initially increase the temperature of the ironing shoe (which is initially at room-temperature) after the ironing shoe is attached to the soleplate. Because the contact area has a limited surface, the heat transfer will not substantially contribute to further increase the temperature of the ironing shoe after the ironing shoe has reached a balanced temperature.
  • the heat conductive protruding structure is made of metal material.
  • conductive protruding structure made of metal material allows an easy and cost-effective way of conducting locally and quickly a limited amount of heat from the soleplate to the plate of the ironing shoe.
  • the heat conductive protruding structure is cylindrical or oval shaped.
  • Forming the heat conductive protruding structure with those shapes allows an easy manufacturing.
  • the heat conductive protruding structure comprises at least one bump.
  • Forming the conductive protruding structure as bump(s) allows an easy manufacturing of the heat conductive protruding structure in the plate.
  • the at least one bump corresponds to a stamped portion in the plate.
  • stamping for forming the bump(s) allows an easy and cost-effecting manufacturing.
  • the heat conductive protruding structure is arranged in a central part of the ironing shoe and/or extends along a longitudinal axis of the ironing shoe.
  • Having the conductive protruding structure arranged in a central part of the ironing shoe allows an even distribution of heat from the soleplate to the ironing shoe after the ironing shoe has been attached to the soleplate. This helps that the condensation of steam will be further limited over a larger area of the ironing shoe.
  • an ironing shoe always have a symmetrical shape, having the conductive protruding structure extending along a longitudinal axis of the ironing shoe also contributes to an even distribution of heat from the soleplate to the ironing shoe.
  • the heat insulating protruding structure and the heat conductive protruding structure have a same height.
  • the plate comprises at least one steam hole, the heat insulating protruding structure being formed on said inside face by a rim extending around the periphery of said at least one steam hole.
  • the heat insulating protruding structure formed as a rim extending around the periphery of the steam hole(s) allows an easy manufacturing. Moreover, the relatively long length of the heat insulating protruding structure around each steam hole also contributes to have a stable contact of the ironing shoe with the soleplate.
  • the rim has a height in the range [0.1; 1.5] mm.
  • the heat insulating layer comprises portions having different thickness.
  • Having insulating layer comprising portions having different thickness avoids that some part(s) of the ironing shoe would receive too much heat form the soleplate. This thus helps the ironing shoe to receive heat evenly from the soleplate.
  • a first portion of the heat insulating layer has a thickness in the range [0.5; 1] mm, and a second portion of the heat insulating layer has a thickness in the range [1; 2] mm.
  • This aspect of the invention results in cost benefit for the first portion, and increased structural strength for supporting rubber rim(s) in the second portion.
  • the air gap has a value in the range [0.1; 3] mm, preferably in the range [0.2; 1.5] mm.
  • This range of value for the air gap allows an optimal heat transfer from the soleplate to the plate of the ironing shoe, so that the external face of the ironing shoe is kept within an optimal and relatively low range of temperature compared to the soleplate temperature.
  • the ironing shoe comprises first attaching means for removably attaching the ironing shoe to the soleplate.
  • the invention also relates to a garment care device comprising a soleplate for treating garments, and second attaching means for attaching an ironing shoe as described above via the first attaching means.
  • Fig. 1A depicts an ironing shoe 100 according to the invention when being detached from the soleplate 101 of a garment care device 102, such as a steam iron, as illustrated.
  • the ironing shoe 100 comprises a plate 103 comprising an outside face 104 intended to come into contact with garments to be treated, and an inside face 105 intended to face the soleplate when the ironing shoe 100 is attached to the garment care device.
  • the plate 103 is preferably made of metal, such as aluminium or stainless steel.
  • the plate 103 has a thickness in the range [0.6; 1.5] mm, preferably 0.8 mm.
  • the outside face 104 and the inside face 105 of the plate 103 are preferably flat, so that they extend parallel to the surface of the soleplate 101 when the ironing shoe is attached to the garment care device 102.
  • Fig. 1B depicts the ironing shoe of Fig. 1A when being attached to the soleplate of the steam iron.
  • the inside face 105 comprises:
  • the heat insulating layer 106 is for example made of a silicone rubber layer(s) coated on the inside face 105.
  • the heat insulating protruding structure 107 is a structure protruding from the inside face 105.
  • the heat insulating protruding structure 107 is intended to come into contact with the soleplate 101 when the ironing shoe is attached to the garment care device 102.
  • the heat insulating protruding structure 107 has a height larger than any other elements in the inside face 105, in particular larger than the height of the heat insulating layer 106, this helps creating an air gap AG between the heat insulating layer 106 and the soleplate when the ironing shoe 100 is attached to the garment care device.
  • the heat insulating layer 106 and the air gap act as insulation layers which ensures that the temperature of the plate 103 will remain in a range of temperature [100; 150] degrees when the temperature of the soleplate 101 is in a range of temperature [160; 235] degrees.
  • the air gap AG is illustrated on Fig. 3A , Fig. 3B .
  • the heat conductive protruding structure 108 is a structure protruding from the inside face 105.
  • the heat conductive protruding structure 108 is intended to come into close contact with the soleplate 101 when the ironing shoe is attached to the garment care device 102.
  • the heat insulating protruding structure 107 and the heat conductive protruding structure 108 have a same height (h).
  • both the heat insulating protruding structure 107 and the heat conductive protruding structure 108 come into direct contact with the soleplate 101 when the ironing shoe is attached to the garment care device 102.
  • the height (h), calculated from the bottom of the inside face 105, is illustrated on Fig. 4B, Fig. 4D .
  • the heat conductive protruding structure 108 has a top part defining a contact area with the soleplate.
  • the contact area of the heat conductive protruding structure 108 with the soleplate corresponds to the sum of the separate top part surfaces, such as the sum of the surface of the three top part circles in the example of in Fig. 2A .
  • the ratio between the surface of said contact area and the surface of the inside face 105 is in the range [0.5; 30.0] %.
  • the surface of the inside face 105 of an ironing shoe 100 adapted to be removably attached to a garment care device 102 corresponding to a steam iron is in the range [18000; 24000] mm2.
  • the surface of the inside face 105 is (nearly) same as the surface of the soleplate 101.
  • the surface of the inside face 105 is 22000 mm2.
  • the heat conductive protruding structure 108 is made of three separate bumps having circular top parts with diameter 10mm.
  • each bump is about 78.5 mm2.
  • the ratio between the surface of said contact area and the surface of the inside face 105 is thus about 1%.
  • the heat conductive protruding structure 108 is made of metal material, such as aluminium or stainless steel.
  • the heat conductive protruding structure 108 is cylindrical (as illustrated in Fig. 2A ), or oval shaped.
  • the heat conductive protruding structure 108 comprises at least one bump, such as bumps B1, B2, B3, as illustrated in Fig. 2A .
  • the at least one bump B1, B2, B3 corresponds to a stamped portion in the plate 103 as illustrated in Fig. 4B .
  • the heat conductive protruding structure 108 is arranged in a central part of the ironing shoe 100, as illustrated in Fig. 2A .
