Definitions

  • the present invention relates to the field of portable steaming apparatus comprising a handle, a steam emitting head connected to an upper end of the handle and a base connected to a lower end of the handle, in which the base comprises a generator steamer and the handle includes a steam duct connecting the steam generator to at least one steam outlet hole on the head.
  • a portable steamer comprising a steam emitting head connected to an upper end of the handle, the steam emitting head comprising a treatment face, provided with steam outlet orifices, intended to come vertically into look of a garment to be smoothed when the device is held with its handle oriented substantially vertically.
  • the apparatus disclosed in this document comprises a vaporization chamber arranged in the base and connected to the head by a vapor conduit passing through the handle.
  • Such a device has the advantage of having a steam generator which is arranged in the base so that the balance of the masses thus procured offers good ergonomics of use. Indeed, the weight of the generator being located under the handle, the latter does not generate a torque tending to twist the user's wrist when the device is held vertically.
  • the present invention aims to remedy this drawback.
  • the subject of the invention is a portable household appliance for smoothing creases comprising a body comprising a handle and a steam connected to an upper end of the handle, the steam emitting head comprising a treatment face, provided with at least one steam outlet hole, intended to come opposite a garment to be smoothed, the handle comprising a wall intended to be grasped by the user's hand and enclosing a steam conduit connected to said at least one steam outlet hole, characterized in that the body of the household appliance comprises at least a first pair of openings configured to be able to generate cooling of the handle by thermal convection.
  • the solution provided by the present invention is advantageously based on cooling the handle by thermal convection, namely by air movement in a vertical plane.
  • This thermal convection therefore allows heat transfer by means of a displacement of a fluid, such as air, in a vertical plane.
  • the device comprises at least one lower orifice and one upper orifice placed at two different altitudes, so as to allow the installation by convection of an air flow which will cool the handle.
  • the apparatus may further have one or more of the following characteristics, taken alone or in combination.
  • the first pair of openings comprises at least one lower ventilation orifice and at least one upper ventilation orifice, the upper ventilation orifice being arranged in the head and being advantageously separate from the lower ventilation opening by an altitude difference of at least 5 cm when the treatment face is placed vertically with the handle pointing downwards.
  • handle pointing downwards it is meant that the handle is with its lower end as low as possible while having the treatment face in a vertical plane.
  • the body comprises a base connected to a lower end of the handle and containing a steam generator, the lower ventilation orifice being arranged in the base.
  • the steam emission head comprises a through channel which opens onto the treatment face and allows visual access through the steam emission head, the upper ventilation orifice being made in the through channel.
  • the handle contains a sleeve extending around the steam duct to limit the heat transfer between the wall of the handle and the steam duct.
  • Such a sleeve forms a thermal barrier around the steam duct which limits heat transfer and therefore heating of the handle.
  • the sleeve is constituted by an added piece inside the handle.
  • the sleeve is made of plastic material.
  • the first pair of openings generates, by convection, a first flow of air flowing in the handle, inside the sleeve and the body comprises a second pair of openings which generates a second airflow, flowing into the handle, outside the sleeve.
  • the second pair of openings comprises at least one lower ventilation opening provided in the base and at least one upper ventilation opening provided in the handle.
  • the body comprises a second pair of openings, configured to be able to generate, by thermal convection, a cooling of the handle.

  • the steam emission head 3 comprises a front end provided with an end plate 5, advantageously metallic, having a flat treatment face 50 intended to come vertically opposite a garment to be smoothed and comprises a through channel 30 which opens, on the one hand, on the treatment face 50 and, on the other hand, on a rear face of the head 3.
  • the treatment face 50 and the end plate 5 have a generally triangular shape, the through-channel 30 extending longitudinally to the vapor emission head 3 while being centered with respect to the latter.
  • the through channel 30 has a first diverging end which opens at the center of the treatment face 50 and a second diverging end which opens at the center of the rear face of the head 3.
  • the first diverging end of the through channel 30 as well as the face treatment 50 has several holes 51 steam outlet.
  • the vapor emission head 3 contains a tank 6, preferably arranged in a rear part of the head 3, having a transparent outer wall and comprises a removable cap 60 allowing the tank 6 to be filled.
  • the steam generator 4 is fed by gravity with water from the reservoir 6 and comprises an instantaneous vaporization chamber 40 formed in an aluminum foundry containing, in a manner known per se, an electrical resistor 41 whose supply is regulated by means of a thermostat 42.
  • the reservoir 6 is connected to the vaporization chamber 40 by a supply conduit 7 extending inside the handle 2, the conduit supply 7 being advantageously equipped with a distributor 70 making it possible to control the passage of water through the supply conduit 7.
  • the distributor 70 can be constituted by a valve brought back into a closed position of the supply duct 7 by return means, such as a spring, and brought into an open position of the supply duct 7 when pressure is exerted manually on a trigger 71 arranged on the front face of the handle 2 .
  • the vaporization chamber 40 is connected by a vapor conduit 8 to a vapor diffusion chamber 52 formed in a body arranged in thermal contact with the end plate 5, the vapor diffusion chamber 52 communicating with the holes 51 steam outlet.
  • the steam conduit 8 is connected to a steam outlet orifice 41 formed on an upper face of the vaporization chamber 40 and travels vertically through the handle 2, then under the reservoir 6 to be connected to an inlet orifice of the vapor diffusion chamber 52.
  • the handle 2 formed by assembling the front 10A and rear 10B shells of the body 10, comprises a wall, with a thickness of the order of 2 min, intended to be gripped by the hand of the user, the wall of the handle 2 having an internal surface which delimits a volume in which the steam duct 8 and the supply duct 7 travel in particular.
  • the handle 2 comprises a sleeve 9 comprising a wall extending around the steam duct 8, the sleeve 9 comprising a lower end coming into contact with a cover 43 which covers the steam generator 4 and comprising an end upper which reaches the level of the upper end of the handle 2.
  • the sleeve 9 comprises a body of generally tubular shape, made of plastic material, extending longitudinally to the handle 2, the steam conduit 8 passing through a lower opening made at the lower end of the sleeve 9 and through an upper opening made at the upper end of the sleeve 9.
