Definitions
- the present invention relates to an injection device for a steam iron.
- This device more particularly comprises a nozzle mounted in an opening in a wall separating a water tank and a vaporization chamber located in service below the tank.
- the nozzle comprises an annular lip delimiting a communication orifice between the reservoir and the chamber, and a skirt surrounding the flow passage downstream of the lip relative to the direction of flow.
- the device further comprises a needle having a lateral recess and movable axially in the orifice between a closed position where the lip surrounds the needle between a free end of the latter and the lateral recess, and an injection position where the lip surrounds the needle between the two axial ends of the lateral recess.
- Such a device is known from FR-A-2 449 157.
- the needle passes from one to the other of its extreme positions, it makes the lip work in flexion, which descales it.
- the smooth region being in service below the axial recess, the needle can be passed into the injection position by simple downward pressure, which is convenient.
- an injection device comprising a concave conical seat followed on the lower side by a calibrated cylindrical orifice.
- a valve movable along the axis of the nozzle cooperates with the seat and further carries a needle engaged in the calibrated orifice when the valve is in the closed position.
- the needle When the valve is instead detached from its seat, the needle is above the orifice and the water flows in principle at a flow rate determined by the calibration of the orifice.
- the valve returns to the closed position, the needle pushes down the scale deposit that may have formed in the orifice, and prevents the orifice from being completely occupied by scale if the device is not operated for a while.
- the object of the invention is thus to propose an injection device of the kind stated at the beginning, by which the tartar sheath capable of surrounding the smooth region of the needle is effectively eliminated.
- the water injection device is characterized in that the skirt is flexible and in that the needle carries axially beyond its smooth region a bulge surrounded by the skirt in the closed position of the needle.
- the iron comprises a plastic casing 1 surmounting a heating sole 2.
- a vaporization chamber 3 is arranged between the upper face of the heating sole 2 and a sheet metal wall 6b.
- the heating sole 2 is traversed by steam distribution openings (not shown) through which the vaporization chamber 3 communicates with the outside, under the sole 2.
- the housing 1 contains a water tank 4 whose lower wall 6a, made of metal sheet, is situated above the upper wall 6b of the chamber 3. Between the walls 6a and 6b is formed a hollow space 6c, having for aim of avoiding the heating of the water and the formation of vapor in the tank 4.
- the walls 6a and 6b are substantially horizontal in the iron operating position in which the soleplate 2 is itself horizontal.
- An opening 7 passes through the walls 6a and 6b.
- the nozzle 8 of a water injection device 9 selectively allowing the water contained in the tank 4 to pass drop by drop by gravity into the vaporization chamber 3.
- the nozzle 8 comprises a tubular body 11 whose annular end directed towards the reservoir 4 has a flange 12 bearing, around the opening 7, under the sheet 6a adjacent to the tank 4.
- the sheet 6a itself around the opening 7 a cylindrical rim 13 fitted into the body 11.
- a metal tube 14 is crimped by its end directed towards the chamber 3 on the edge which has all around the opening 7 the sheet 6b adjacent to the chamber 3.
- the tube 14 is fitted without play in the body 11 and extends to an annular wing 16 of the body 11, directed radially inwards.
- the body 11 is thus centered by the rim 13 and the tube 14, and it is positioned axially between the tube 14 and the sheet 6a.
- the wing 16 carries a flexible annular lip 17 delimiting by its free edge a circular orifice 18 ( Figure 2).
- the lip 17 is offset towards the tank 4 relative to the sheet 6b so as to be protected as much as possible from the heat given off by the heating sole 2.
- the wing 16 On its face facing the vaporization chamber 3, the wing 16 carries the inside the metal tube 14 a skirt 19 having a cylindrical inner wall with a diameter greater than that of the orifice 18. Over most of its axial length, the skirt 19 is surrounded by a free space 20 separating it radially from the tube 14 .
- the space 20 extends to the free end 33 that the skirt 19 presents towards the chamber 3, and thus communicates with the chamber 3 all around the skirt 19.
- the end 33 of the skirt 19 protrudes from the tube 14 to the vaporization chamber 3.
- the body 11, the flange 12, the wing 16, the lip 17 and the skirt 19 are produced in a single block of silicone resin.
- the injection device 9 further comprises a needle 21 constituted by a rod of generally cylindrical shape made of a plastic material resistant to temperature.
- the rod 21 extends along the axis XX of the nozzle 8 and in particular of the orifice 18, this axis being perpendicular to the plane of the walls 6a and 6b and of the heating sole 2.
- the needle 21 is fixed to a pusher 22 mounted to slide along the axis XX in a barrel 23.
- the pusher 22 is connected to a push button 24 projecting from the top of the housing 1.
- the needle 21 comprises in the vicinity of the pusher 22 a lateral recess 26 constituted by a groove directed parallel to the axis X-X.
- the area of the section of the groove 26 considered in a plane perpendicular to the axis XX decreases in the direction of the heating sole 2. This can be seen in Figures 1 and 4 from the decreasing depth of the groove 26.
- the needle 21 has a smooth cylindrical region 28.
- the diameter of the needle 21 in the region having the groove 26 and in the region 28 is greater than the diameter of the orifice 18 before mounting of the needle 21, and is less than the internal diameter of the skirt 19.
- the needle 21 constantly tends to return to a closed position ( Figure 1) in which the lip 17 surrounds the smooth cylindrical region 28 of the needle 21. In this position, the needle 21 closes the orifice 18 and consequently prevents the flow of water to the vaporization chamber 3.
- the button 24 By pressing the button 24 ( Figure 4) the user can move the needle 21 along the axis XX until the lip 17 surrounds the needle 21 in the region having the groove 26. Therefore ( Figures 4 and 5 ) the groove 26 allows, through the orifice 18, a calibrated leak from the reservoir 4 towards the vaporization chamber 3. Taking into account the non-constant section of the groove 26, the flow rate towards the vaporization chamber 3 is all the more important that the needle 21 is strongly moved towards the sole 2, which the user can adjust by pressing button 24 more or less.
- the flexible lip 17 is biased in bending by the axial movements of the needle 21, which descales it.
- the water which reaches the end 33 falls into the chamber 3 instead of spreading laterally towards the tube 14 and of forming scale in this region.
- the formation of tartar is therefore reduced.
- a tubular deposit is formed inside the skirt 19 having in section the shape shown in dotted lines at 29 in FIG. 1 and if no provision is made against such a deposit 29, the needle 21 is braked or blocked in its movements; in addition, the scale deposit can seal between the skirt 19 and the needle 21 and thus prevent flow even when the needle 21 is in the injection position.
- the lip 17 in the plane of the sheet 6b, but this would have the disadvantage of subjecting it more to heating by the sole 2.
- the needle 21 would be too close to the sole 2 in the injection position.
- the skirt 19 has in the radial direction a thickness allowing it a certain flexibility taking into account the material (silicone resin) in which it is made.
- the needle 21 has at its free end 27 directed towards the sole 2, an annular bulge 31 having, in section along a plane passing through the axis XX, an isosceles triangle section whose base is parallel to the axis XX.
- the external diameter of the bulge 31 is less than the internal diameter of the skirt 19.
- the bulge 31 has an external diameter allowing it to cross the lip 17 by simple elastic deformation of the latter, which makes it possible to dismantle the needle 21 by the top for cleaning.
- the bulge 31 When the needle 21 is in the closed position, the bulge 31 is surrounded by the skirt 19 ( Figure 1).
- the distance between the bulge 31 and the axial end 32 that the groove 26 presents in the direction of the bulge 31 is greater than or equal (equal in the example shown) to the distance between the lip 17 and the annular end 33 that the skirt 19 has on the downstream side, that is to say towards the sole 2.
- the fragments of tartar are thus permanently removed from the injection device.
- the bulge can be located below the free end of the needle and it can have a different profile from that described and shown.
