Definitions

  • the invention relates to steam irons which include a heating sole having on its underside a series of steam outlet holes and on its upper side a vaporization chamber communicating with a supply of pressurized water by means of a tap with adjustable flow rate comprising a rotary plug which is rotatably connected around a vertical axis of a shaft linked to a button placed in the upper region of the iron, and which is mounted in a distribution chamber having an orifice inlet connected to the water supply and an outlet orifice made in its bottom wall and opening into said vaporization chamber.
  • the object of the invention is to produce taps which do not have the drawbacks explained above and which can be easily manufactured and assembled in large series.
  • the dispensing chamber comprises a seat having a hole connected to the outlet orifice and a smooth upper surface transverse to the vertical axis and in which a groove of variable section extending extending along a curve and one end of which is connected to said hole, while the plug comprises a head whose active face turned towards the seat and transverse to the axis is smooth and is applied in a sealed manner on the seat, said head comprising a clean flow passage leading to the groove and moving above this groove as a function of the angular position of the rotary plug.
  • valve thus produced allows mass production since the active surfaces are transverse to the vertical axis and are applied one against the other without requiring precise dimensions and therefore adjustment.
  • it is known to produce, without any problem, flat and smooth surfaces with molds of simple design.
  • this sealed contact between planar surfaces does not cause any significant friction, thus providing greater convenience when adjusting the button, and making it possible to work with a pressure of a few hundred millibars in the chamber.
  • Figure 1 shows, in partial section, part of an iron equipped with a valve according to the invention
  • Figure 2 is an enlarged view of the valve of Figure 1
  • Figure 3 is a horizontal section along the line III - III of Figure 2
  • Figure 4 is a vertical section along the line IV - IV of Figure 2 and illustrating a detail of the valve relating to the outlet.
  • the iron partially represented in FIG. 1 comprises a heating sole 1 having on its lower face 2 a series of steam outlet holes 3 and on its upper face a vaporization chamber 4 communicating with a water supply tube 5 under pressure by means of a tap 6.
  • the tube 5 is connected to an independent water tank (not shown) by means of a pump (not shown) intended to send water under a pressure of a few hundred millibars.
  • a trigger 7 mounted in the handle of the iron makes it possible to cut off the water supply to the tap 6 by stopping the control of the pump and by crushing the water inlet tube.
  • the water tube 5 includes a filter 8.
  • the tap 6 is of the adjustable flow type and comprises a rotary plug 9 which is integral in rotation about a vertical axis with a shaft 10 linked to a button 11 placed in the upper region of the iron, and which is mounted in a distribution chamber 12 having an inlet orifice 13 connected to the water supply tube 5 and an outlet orifice 14 formed in its bottom wall 15 and opening into said vaporization chamber 4.
  • the distribution chamber 12 comprises a seat 16 having a hole 17 connected to the outlet orifice 14 and a smooth upper active surface 16 'transverse to the vertical axis and in which is formed a groove 18 with cross-section variable extending along a curve and comprising one end 19 connected to said hole 17 and one blind end 22, while the plug 9 comprises a head 20 whose active face 20 ′ facing the seat 16 and transverse to the axis is smooth and is applied in a sealed manner on the seat, said head 20 comprising a flow passage 21 capable of opening onto the groove 18 and of moving above this groove as a function of the angular position of the rotary plug 9.
  • the curve of the groove 18 extends along a sector of a circle and leaves between the ends 19 and 22 of this groove a flat and smooth region 23.
  • the section of the groove 18 has a constant width and a variable depth. At the end 22, the depth is minimal, then gradually increases until its end 19.
  • the connection between the groove 18 and the hole 17 is obtained by a radial slot 24 originating at the end 19 of the groove.
  • the groove 18 is extended beyond the slot 24, and has a uniform depth slightly greater than that of the end 19, so as to maintain a high flow rate when the passage 21 is placed above this extension.
  • a tap with adjustable flow rate is obtained which is simple and reliable to manufacture, since, on the one hand, the active surfaces 16 ′ and 20 ′ are produced by flat and smooth faces which provide between they a sufficient seal without requiring a significant axial force of friction, and on the other hand, the groove 18 is formed in a flat surface by means of a simple impression mold, and cooperates with the passage 21 which is formed in the head 20 without excessive dimensional accuracy, since its overlapping of the groove 18 ensures the flow without leakage of water in said groove.
  • the invention provides that the plug 9 is mounted axially movable on the shaft 10 connected to the button 11 against an elastic means 25 (shown diagrammatically in broken lines) such as a calibrated coil spring which tends to push the smooth active face 20 ′ of the head 20 against the smooth upper face 16 ′ of the seat 16.
  • an elastic means 25 such as a calibrated coil spring which tends to push the smooth active face 20 ′ of the head 20 against the smooth upper face 16 ′ of the seat 16.
  • the shaft 10 is hollow and its lower part 26 carries the plug 9 which comprises a rod 27 integral with the head 20 which enters the shaft 10, the spring 25 being interposed between an internal shoulder 28 formed in the 'shaft, and a shoulder 29 formed between the head and the rod 27.
  • the lower end of said shaft carries a dog 26' which engages with a claw 27 ′ secured to the head 20.
  • the distribution chamber (12) is formed in a body 30 molded and made of an elastomer, preferably a silicone, capable of withstanding the temperature prevailing in the vicinity of the chamber 4
  • This body 30 come in one piece, has the shape of a well, the bottom of which comprises the seat 16, and the outlet orifice 14, and the side wall of which constitutes the side wall of the chamber 12, comprises a pipe 31 connecting the inlet orifice 13 of said chamber with the water supply tube 5, while the internal edge 32 of the opening of this well has a groove 33 for receiving a lip seal 34
  • This annular lip seal 34 seals between the chamber 12 and the outer wall 35 of the shaft 10.
  • the head 20 of the plug 9 is made of a polyamide such as nylon so that the contact between the active faces 16 ′ and 20 ′ has a lower coefficient of friction and therefore a torque also weak.
  • this body 30 has on its external wall and in the region surrounding the outlet orifice 14 a sleeve 36 forming a seal for the connection of the valve with the vaporization chamber 4.
  • the outlet orifice 14 comprises a valve 37 coming in one piece with the body 30.
  • This valve 37 has the general shape of a tube, the lower region of which is crushed to form two contiguous lips 38 and 39.
  • the valve as shown operates in the following manner.
  • the user wants to iron a synthetic fabric.
  • the active face 20 ' applied with a constant force to the surface 16' by means of the calibrated spring 25, slides in leaktight fashion and brings the flow passage 21 for example in the vicinity of the end 22 of the groove 18.
  • the pressurized water arrives via the pipe 31 in the distribution chamber 12 above the head 20 of the plug 9 and flows through passage 21 in the groove 18.
  • the depth is minimal, the flow of water is restricted and only occurs at low flow.
  • the water flows into the groove 18 then into the slot 24, then passes through the hole 17 and the outlet orifice 14, to arrive in the valve tube 37 and slightly separate the lips 38 and 39 causing only a low vaporization and therefore a low flow of vapor.
  • the passage 21 is brought to the level of the end 19, that is to say in the deepest region of the throat 18.
  • the flow through the passage 21 takes place at a high flow rate and causes a greater separation of the lips 38 and 39 and therefore a strong spraying with a high flow rate of vapor.
  • the passage 21 is brought to the flat region 23, so as to then seal off the outlet of this passage 21.
  • the iron is equipped with a water spraying device 40 which is connected to the distribution chamber 12 by means of a valve 41 arranged in the hollow shaft 10 and controlled by a pressure lever 42.
