Definitions

  • the invention relates to a steam iron pump assembly including a two-position selector with a first position for obtaining a sudden discharge of steam and a second position for obtaining a spray of cold water.
  • steam irons comprise a heating sole plate having a series of steam outlet holes in its bottom face and a steam-generating chamber in its top face which is in communication with said holes and which also communicates with a tank of water via an adjustable low flow rate tap under the control of a rotary knob located on the top portion of the iron.
  • steam irons are generally fitted with a pump suitable for taking a quantity of water from the tank and for delivering said quantity via a selector member either into the steam-generating chamber in order to obtain a sudden and abundant discharge of steam through the holes in the sole plate, or into a cold water spray head situated towards the front of the iron.
  • a sudden discharge of steam or "steam surge” is advantageous for creasing thick cloth, e.g. trouser creases. Cold water is sprayed to eliminate unwanted wrinkles, in particular in cloth which is too dry.
  • the functions associated with the pump and with the selector are separate: there is thus an independent selector connected downstream from the pump and having two outlets for directing water to one or other of two pipes one associated with discharging additional steam and one with spraying cold water.
  • US Patent No. 3,599,357 describes in Figure 8, a rotary selector mounted inside an iron and actuated by a rod extending through the top portion of the iron.
  • the rotary selector is in the form of a two-outlet cylindrical valve. Sealing is very difficult to obtain with such a design and its structure greatly complicates assembly operations.
  • the steam iron described in that patent is still available commercially and includes an independent selector, in the form of a tray, having an inlet orifice and two outlet orifices in communication therewith, with the top of the tray being closed by a rotary actuator lever in the form of a plate having a circular bottom opening capable of putting the inlet orifice into communication with one or other of the outlet orifices, depending on the angular position of the lever.
  • the pump assembly described in this patent comprises a pump body constituting the rotary selector of a plug-type cock or tap.
  • the bottom portion of the pump body is then provided with a conical extension having a lateral orifice, said conical extension being surrounded by a conical rubber sleeve having two opposed orifices and prevented from rotation by a pin.
  • French Patent No. 2,516,561 describes a pump assembly of complex structure having a large number of gaskets, including a rotary seal in the from of a curved half-lip which is difficult to make and to install.
  • this pump assembly suffers from other major drawbacks inherent in its design: it is difficult to assemble since there are numerous close tolerances; high friction on large diameters requires the application of lubricating grease and the overall size of the assembly remains relatively large.
  • EP-A-80 634 describes a steam pressing iron comprising a heating soleplate which is provided on its underside with a series of steam exit openings and on its upper side with an evaporator chamber in communication with the openings and connected to a water reservoir via a cock having a small controlled flow rate, said flow rate being controlled by a rotatable handle mounted on the upper portion of the pressing iron, wherein the pressing iron further comprises a reciprocating pump for withdrawing a measured quantity of water from the reservoir and delivering said quantity by means of a rotatable selector member either to the evaporator chamber in order to achieve a sudden powerful emission of steam through the openings in the soleplate or to a coldwater atomiser disposed in the forward portion of the pressing iron, and in which the reciprocating pump includes a piston for movement inside a cylindrical intake chamber communicated to the reservoir via a non-return valve, characterised in that the intake chamber is formed in the central region of the rotatable selector member and is communicated to the interior of a fixed annular cup
  • a more particular object of the invention is to provide a pump assembly which is highly satisfactory with respect to sealing and reliability, which is simple in design, having as few parts as possible, which is relatively small in size, and which is easy to assemble.
  • the present invention provides a steam iron pump assembly with a two-position selector having a first position for obtaining a sudden discharge of steam and a second position for obtaining a spray of cold water
  • the pump assembly comprises: a pump body surmounted by a deformable bellows defining a pump chamber, the bottom of the pump body having a suction duct and two vertically spaced-apart side outlets each opening out via an associated orifice into a central hollow of said body; a rotary selector inside the deformable bellows and including a bottom portion disposed inside the central hollow of the pump body, and including a top actuator portion constrained to rotate with said bottom portion, said top and bottom portions being free to slide axially relative to each other; a selectively deformable sealing sleeve directly surrounding the bottom portion of the rotary selector, level with the two side outlets from the pump body and characterized in that the sealing sleeve is essentially stationary within the central hollow; and the bottom portion of the rotary selector having an external profile making it
  • the bottom portion of the rotary selector preferably has two identical profiles which are angularly offset relative to each other, and which are spaced apart vertically to correspond to the side outlets of the pump body: for example, the profiles of the bottom portion of the rotary selector are generally rectangular in shape and/or are offset by about 90°.
  • the central hollow of the pump body prefferably has a cross-section which is axially uniform, said cross-section defining a complex profile forming axial thrust faces for compressing the sealing sleeve against one or other of the outlet orifices, and side depressions allowing water to pass around said sleeve;
  • two small axial facets may be provided on either side of each outlet orifice extending substantially perpendicularly to the axis of each side outlet, and an opposite, larger axial facet may also be provided parallel to the small facets.
  • each of the side outlets from the pump body to provided with a non-return valve preventing air being sucked in therethrough, and facilitating pump priming.
  • the top portion of the rotary selector comprises an actuator lever outside the deformable bellows and an intermediate shaft passing through the bellows and providing the rotary connection between the actuator lever and the bottom portion of the rotary selector; in particular, the bottom end of the intermediate shaft may slide in a complementary axial hollow in the bottom portion of the rotary selector, with the corresponding cross-sections preferably being substantially rectangular.
  • the actuator lever is mounted on a pushbutton for actuating the pump in both of the angular positions of the rotary selector, in particular the actuator lever and the intermediate shaft are constituted by a single part.
  • the pushbutton, the actuator lever, and the intermediate shaft constitute a single part, or the pushbutton and the actuator lever may constitute a single part.
  • the intermediate shaft prefferably has a cylindrical portion where it passes through the deformable bellows and for the deformable bellows to be provided with a small cylindrical sleeve in which the cylindrical portion is received, with the inside wall of the small cylindrical sleeve being provided with circular grooves in order to improve sealing; in particular the cylindrical portion of the intermediate shaft may come into abutment against the bottom portion of the rotary selector at the end of the pump-actuating stroke.
  • the axial hollow complementary to the bottom portion of the rotary selector may extend to the bottom end of this portion by means of a bore for the purpose of balancing pressure inside the pump.
  • FIGS. 1 and 2 show a steam iron pump assembly 100 in accordance with the invention.
  • This pump assembly is of the type having a two-position selector in which a first position serves to obtain a sudden discharge of steam or "steam surge", and a second position serves to obtain a spray of cold water.
  • the pump assembly 100 comprises a pump body 101 topped by a deformable bellows 102 defining a pump chamber 103.
  • the bottom of the pump body 101 has a suction duct 104 together with two lateral outlets 105 and 106 one above the other and opening via corresponding orifices 107 and 108 into a central hollow 110 of the pump body.
  • the pump body 101 together with its suction duct and its two side outlets, constitutes a single part which is preferably made of plastics material.
  • the bottom of the pump body 101 has a suction orifice 109 which may optionally be closed by a bead 124; however the bead is not essential because the way in which the pump assembly 100 operates, as explained below.
  • Each of the outlets of the pump body 101 is preferably fitted with a non-return valve to prevent air being sucked in and also to facilitate pump priming.
  • the non-return valves are two beads 125 and 126 associated with the corresponding outlets 105 and 106 of the pump body 101. The beads 125 and 126 are urged into place by the corresponding associate springs 127 and 128.
  • the outlets 105 and 106 are each fitted with end fittings 129 and 130, each end fitting being adapted to receive a flexible hose 131 or 132.
  • the side outlet 106 may correspond, for example, to the sudden discharge of steam or "steam surge", while the lower side outlet 105 corresponds to the spraying of cold water.
  • the bottom suction end piece 104 is similarly adapted to be fixed to a flexible hose 133 whose other end dips into the water tank of the iron (not shown).
  • the pump body 101 finally also includes a shoulder 134 which serves as an abutment to the bottom portion of the deformable bellows 102 topping the pump body.
  • the pump assembly 100 includes a rotary selector 111 passing through the deformable bellows 102 and including a bottom portion 112 disposed in the central hollow 110 of the pump body 101, together with a top actuator portion 113 constrained to rotate with said bottom portion but capable of sliding axially relative thereto.
  • the pump assembly also includes a sealing sleeve 114 directly surrounding the bottom portion 112 of the rotary selector 111 at the level of the two side outlets 105 and 106 of the pump body 101.
  • the bottom portion 112 of the rotary selector 111 has a profile making it possible, depending on the angular position of the rotary selector, to apply the sealing sleeve 114 against one of the outlet orifices (107 or 108) while simultaneously allowing water to pass to the other of the outlet orifices (108 or 107).
  • deformable sleeve being essentially stationary with respect to rotation is particularly advantageous in practice since it makes it possible to reduce considerably the friction at the outlet orifices 107 and 108, unlike known designs which use a non-deformable sleeve which is caused to rub against the outlet orifices.
  • Such a system also has the advantage of taking up very considerable amounts of slack, thereby allowing much less severe manufacturing tolerances to be used, than for prior art designs.
  • the desired outlet is selected solely by radial deformation of the sealing sleeve 114, the deformation occurring simultaneously in that portion of the sleeve which faces the bottom orifice 107 and the other portion which faces the other orifice 108, the two deformations being angularly offset relative to each other as explained below.
  • annular shoulder 135 whose main function is to keep the sealing sleeve 114 in position engaged between the lower edge of said shoulder and the tapering end of the central hollow 110 in the pump body 101.
  • This shoulder 135 may also be used for holding the bottom portion 112 of the rotary selector 111 in its axial position within the pump body 101, by means of a washer 136 bearing against the top edge of said shoulder and also against a shoulder 137 provided in the top portion of the pump body 101, which shoulder 137 is shown in Figures 17 and 18.
  • the "steam surge" position i.e. when the rotary selector 111 occupies an angular position such that the sealing sleeve 114 is pressed closely against the orifice 107 of the outlet 105, then the other orifice 108 is automatically disengaged, given that the radial deformation of the sealing sleeve 114 is then applied in a direction which is substantially perpendicular to the first direction of radial deformation causing the bottom orifice 107 to be closed.
  • the cross-section of the central hollow 110 is uniform in the axial direction of the pump body, the section defining a complex profile forming axially-extending thrust facets 138 and 139 allowing the sealing sleeve 114 to be pressed securely against one or other of the outlet orifices 107 and 108.
  • These two small axial facets 138 and 139 are provided on either side of each outlet orifice 107 and 108 and thus extend substantially perpendicularly to the axis of each side outlet 105 and 106 and, in addition, a larger opposed axial (i.e. axially-extending) facet 140 is also provided parallel to said small facets.
  • the disposition of these axial thrust facets thus makes is possible to compress the radially deformed part of the sealing sleeve 114 firmly against the associated orifice 107 or 108, thereby obtaining excellent sealing.
  • two side depressions 141 are also provided to allow water to pass around the sealing sleeve 114, with said side depressions being defined, for example, by profile portions in the form of circular arcs.
  • the complex profile of the cross-section of the central hollow 110 also has pairs of sloping facets at angles c and d , sloping respectively from the axial thrust facets and from the side depressions, where the angles c and d are preferably equal to each other and are selected to be approximately 90°.
  • these facets are interconnected at the four relevant peripheral zones, at the ends of two diagonals, by circular arcs 143 coinciding, for example, with the base circle of the central hollow 110 prior to the hollow being shaped.
  • the principal direction of radial deformation of the sleeve 114 lies along the outlet axis 105 such that the sleeve 114 is compressed between the facet 140 and the two opposed facets 138 and 139, thereby allowing the corresponding orifice 107 to be completely closed, while the side depressions 141 are at maximum volume, thereby allowing water to pass over the periphery of the sleeve 114.
  • a spacing of about 6.6 mm may be selected between the facet 140 and the small facets 138 and 139, with a spacing of about 8 mm between the bottoms of the side depressions 141, in which case the diameter of the base circle, arcs 143 is about 6.8 mm.
  • the top portion 113 of the rotary selector 111 includes an actuator lever 115 outside the deformable bellows 102 together with an intermediate shaft 106 which passes through the bellows and which provides a rotary connection between the actuator lever and the bottom portion 112 of the rotary selector 111.
  • the intermediate shaft 116 has a lower end 117 which is suitable, in this case, for sliding in a complementary axial hollow 108 in the bottom portion 112 of the rotary selector, with the corresponding cross-sections being preferably substantially rectangular.
  • the end 117 of the intermediate shaft 116 is, in practice, in the form of a thin blade suitable for sliding freely in the complementary axial hollow 118 of the bottom portion 112.
  • Figures 8 to 10 clearly show the complementary axial hollow 118 which is extended in this case to the bottom end of the portion 112 by means of a cylindrical bore 123, allowing pressure within the pump to be brought into equilibrium.
  • the bore 123 is not in any way essential, but it is advantageous for pressure-balancing purposes since it avoids setting up high pressure gradients, thereby limiting the risks of leakage in the event of pressure increase, and also ensuring that the delivery rate remains uniform.
  • the intermediate shaft 116 preferably has a cylindrical portion 121 where it goes through the deformable bellows 102, and to this end the bellows has a small cylindrical sleeve 122.
  • the lever 115 can be easily actuated without deforming the bellows 102 radially where the intermediate shaft 116 passes therethrough.
  • the bellows 102' has a top end, which is slightly different from that of the above-described bellows 102 including a small top sleeve 122' provided with circular grooves 144 about its axial bore, as shown more clearly in Figure 21.
  • This makes it possible to define very good point contact between the cylindrical portion 121 of the intermediate shaft 116 and the small sleeve 122' of the sealing bellows 102'.
  • Grease may optionally be provided in the circular grooves 144 in order to provide a self-lubricating system encouraging flexible and reliable operation of the pump.
  • the intermediate shaft 116 has a top end 119 for providing rotary coupling with the actuator lever 115 of the rotary selector 111.
  • this top end 119 is in the form of a flat blade of essentially rectangular cross-section.
  • the actuator lever 115 is mounted in this case on a pushbutton 120 for actuating the pump in either of the angular positions of the rotary selector 111. It is advantageous to integrate the actuator lever 115 fully in the top portion of the pushbutton 120, as shown herein, with one end 145 of the actuator lever being easily displaced with a finger.
  • the actuator lever 115 may advantageously be integrated in the pump actuator pushbutton by a snap-fastening technique which facilitates both assembly and displacement of the actuator lever per se. This integration will be better understood on referring to Figures 5 and 6.
  • Figure 6 shows a position for mounting the lever on the pushbutton 120.
  • the shaft of the actuator lever 115 has two diametrically opposite annular projections 147 suitable for snap-fastening engagement with resilient tabs 148 fixed to the pushbutton 120.
  • the button 120 also has annular shoulders 146 beneath which the projections 147 can pass after snap-fastening, with the assembly then being securely held together in either of the two operating positions as illustrated in Figure 6.
  • Figure 5 also serves to show small bosses 149 provided on the underside of the actuator lever 115, said bosses being suitable for co-operating with radial projections 150 provided on the annular shoulders 146.
  • Figure 6 also shows pictographs 151 and 152 on the top face of the pump actuator pushbutton 120, corresponding respectively to the spray position and to the steam discharge position.
  • the angular stroke of the actuator lever 115 is about 120°. This is not incompatible with the angular offset of 90° mentioned above for the outline of the bottom portion 112 of the rotary selector 111. It can easily be seen that the structure of the pump assembly 100 can readily tolerate an angular range of plus or minus 15° relative to accurate angular positions without any loss of sealing at the closed outlet orifice from the pump body. This constitutes a major advantage compared with the prior art, in particular with techniques making use of a plug-type cock having a side opening, since an angular error of such magnitude would then prevent satisfactory operation.
  • the top portion 113 of the rotary selector 111 is made up of three parts, namely the intermediate shaft 116, the actuator lever 115, and the pump actuator button 120.
  • the number of parts may be reduced to two or even to only one.
  • Figure 14 thus illustrates a variant in which the actuator lever 115' and the button 120' comprise a single part.
  • Figure 15 shows another variant in which the actuator lever 115'' and the intermediate shaft 116'' comprise a single part. These two variants could be combined by causing the actuator lever, the pushbutton, and the intermediate shaft to comprise a single part. This variant is not shown.
  • the intermediate shaft 116 is made of metal, e.g. stainless steel, then the pushbutton and the actuator lever may be provided as a single part, in which case the outside shape of the pushbutton would be cylindrical rather than semi-cylindrical as shown in Figures 5 and 6.
  • the intermediate shaft could be made of a plastics material such as a polyamide or a polycarbonate, in which case a single component could be made comprising two or three of the above-mentioned items.
  • the pump assembly 100 comprises a pump body 101, a bottom portion 112 with its sleeve 114, a deformable bellows 102, and a rotary selector which may be made of one, two or three parts.
  • each of the parts performs a plurality of functions: for example the deformable bellows 102 serves both to define the deformable pump chamber and also to provide the return spring effect for the pump thereby avoiding the need to add an additional return part, while simultaneously ensuring good sealing both where it meets the pump body, radial sealing, and where the intermediate shaft of the rotary selector passes therethrough.
  • the deformable bellows 102 serves both to define the deformable pump chamber and also to provide the return spring effect for the pump thereby avoiding the need to add an additional return part, while simultaneously ensuring good sealing both where it meets the pump body, radial sealing, and where the intermediate shaft of the rotary selector passes therethrough.
  • the sealing of the system is excellent since the deformable sleeve is always compressed in a single direction over each of the orifices in a direction which substantially coincides with the axis of the orifice in question. It is important to observe that no other sealing component is required, with the sealing sleeve 114 and the bellows 102 sufficing on their own to provide all of the sealing required in the assembly.
  • Such an embodiment also serves to avoid friction in the top portion of the rotary selector and this constitutes a considerable advantage over the prior art in which it is necessary to press the actuator lever against a sealing face by means of an additional part.
