  • Still another object of the present invention is to provide an improved electrical steam-spray iron having a combined pump and valve mechanism wherein rocking movement of the piston selects the path of discharge,
  • An even further object of the invention is to provide steam-spray iron which has a bi-stable valve mechanism operable without interruption of the ironing process.
  • an improved steam-spray iron wherein a bistable valve and a manual piston pump share a common housing whereby movement of the pump handle provides a selection of the bi-stable valves stable state and also provides the manual pump action.
  • the bi-stable valve determines whether the water drawn from the reservoir by the pump is distributed to the spray nozzle or down into a steam generating chamber to produce a high velocity steam through steam ports in the sole plate.
  • Rocking movement of the manual pump handle is transmitted to a valve rocker by a spring biased actuator telescopically received within the face of the piston.
  • the valve rocker sits in the base of the combined pump and valve housing and has a center fulcrum which causes the rocker to have only two stable positions.
  • the outlets in the base of the combined housing directs the water either to the spray nozzle or into the steam generating chamber to produce high velocity steam.
  • the lateral selection movement of the pump handle may be made by the user with a single finger, preferably the same finger which operates the pump, and may be made without interruption of the ironing process.

  • spray nozzle 24 also has a unique check valve enclosed therein which will also be discussed later.
  • Iron in FIG. 1 operates in four basic modes.
  • the first mode is a dry mode wherein switch is switched to the dry position which closes a needle valve to prevent water dripping into a steam generating chamber.
  • the third mode is the production of water from spray nozzle 24 selected by lateral or rocking movement of pump button 20.
  • the button has been moved left, as viewed in FIG. 1 to move the bi-stable valve to a first stable position, upward movement of the pump button draws water from reservoir 18 through filter to tube 21 into the housing 19 and downward movement forces the water out of the housing through tube 23 to spray nozzle 24.
  • the fourth mode of operation produces a high velocity steam in which button 20 is rocked in the opposite direction to move the bi-stable valve to a second stable position so as to allow water to be withdrawn from reservoir 18 through filter 25, tube 21, and into valve housing 19 by an upward movement and then to be delivered through tube 22 and check valve 26 into a steam generating chamber by a downward movement.
  • the selection of the third or fourth mode may be made by the users thumb, which may be the same finger used for the updown pump action. Both of these motions of the thumb are made simultaneously with the use of the iron and without interruption of the ironing process.

  • an aperture 36 which continues into the piston rod 33, receives the actuator 37 therein.
  • the diameter of the actuator 37 is smaller than the diameter of the aperture 36 such that the actuator 37 is telescopically received within the piston 32 and moves freely therein.
  • the actuator 37 is shown as having a modified conical head 38 with sides cooperating to form angular surfaces having a partially rounded tip.
  • actuator head 38 It is the shape of actuator head 38 which forms an important camming surface to be used in combination with valve rocker 70 to provide the bi-stable operation of the valve to be explained hereafter.
  • Spring 39 between the face of piston head 34 and the base of actuator conical head 38 provides a biasing means which urges the separation of the actuator 37 from the piston 32.

  • the pump moves up, water is drawn from the reservoir through tube 21, inlets 46 and 45 into the combined pump and valve housing 19.
  • the water in the housing On the downstroke, the water in the housing is forced through one of the openings of valve seats 41 or 42 and into its respective tubes 23 or 22.
  • the outlet through which the water exits the pump base 40 is determined by the position of bi-stable rocket 70. As shown in FIG. 2, the water will exit out of opening 42, outlet 44, and down into tube 22 to the steam generation chamber.
  • FIGS. 3a and 3b An examination of FIGS. 3a and 3b will reveal the precise relationship of the inlet, outlets, and openings and tapered valve seats of the pump base 40.
  • the pump base 40 has an internal structure or member 47 having a slot or recess 48 therein.
  • the valve seats 41 and 42 are in the bottom of said slot or recess and the inlet 46 communicates with the internal inlet 45' at the top of internal member 47.
  • the slot or recess 48 provides a seat for rocker 70 and also provides a stop for actuator head 38, thereby limiting the movement of the combination actuator and thus the piston to lateral movement within the slot or recess 48.
  • the recess does not interfere or in any way limit the vertical pumping action.
  • the spray nozzle 24, as shown in FIG. 2, comprises a base or body 50 which threadably receives nozzle 54 which has an aperture 58 therein.
  • a gasket 55 provides a water-tight seal between the nozzle 54 and the nozzle base 50.
  • On one side of the nozzle base 50 is an inlet 51 for receiving tube 23 which brings water from the combination pump and valve housing 19.
  • Tube 23 and inlet 51 communicate with a duct 52 in the center of the nozzle base 50.
  • Encompassing the end of said duct is a flexible cap valve 53, preferably made of an elastomeric material.
  • the cap valve 53 surrounds the pro jected exterior of the base at the circumferal surface 56.
  • This cap functions as a check valve, allowing water to flow from duct 52 into the interior of the nozzle 54 and out of aperture 58 on the downward stroke of the pump and sealing the end of duct 52 on the reverse stroke of the pump, thus preventing air from being conveyed through tube 23 into the pump and valve housing.
  • valve cap 53 is used in the present spray nozzle 24, any other check valve system may be employed to allow water to enter the nozzle in the downstroke of the pump and to seal the nozzle to prevent air from being injected into the pump during its upstroke.
  • FIG. 2 Another novel check valve 26, shown in FIG. 2, is mounted on the end of tube 22 leading from the housing into the steam generation chamber.
  • the interior of the check valve 26 consists of an upper internal bore 60 and a lower internal bore 62 separated by diaphragm 61.
  • the diameter of upper bore 60 is smaller than the diameter of the lower bore 62.
  • Diaphragm 61 has a slit across its diameter.
  • the diaphragm deforms and opens allowing water under pressure to proceed from tube 22 into a steam generating chamber and it resumes its normal shape and closes the slit upon reverse pressure to prevent water or steam from reentering tube 22 during the reverse action of the pump.
  • the total body of check valve 26 is comprised ofa flexible material and the exterior is shaped so as toprovide a water-tight seal with the steam generating chamber. Obviously, any standard check valve may be utilized on the end of tube 22.
  • a coupling 65 is mounted on the end of tube 21 to receive and maintain the combination filter and check valve 25.
  • the filter and check valve which is more fully discussed below, functions to allow water to be drawn from the reservoir into the pump and valve housing 19 during the upstroke of the pump and to prevent water from leaving the pump housing 19 and re-entering the reservoir. It also prevents residue in the water from leaving the reservoir.
  • the major component of the bi-stable valve is rocker 70, shown in FIG. 2 and shown still more explicitly in FIGS. 4a and 4b.
  • the rocker 70 has a body including a fulcrum surface 71 which lies upon the bottom of the slot or recess 48 in the pump base 40.
  • fulcrum 71 On either side of fulcrum 71 are two hemispherical protuberances 72 and 73 extending from the body. These protrusions are received in openings 41 and 42 of the pump base 40 which are tapered to form seats for the rocker protruberances 72 and 73.
  • On the top surface of the rocker is an angular cam surface or protrusion 74 having the form of an obtuse angle. As can be seenfrom FIG.
  • the rocker 70 is of the same shape as the slot or recess 48 of the pump base. This allows the rocker to sit in the base and teeter therein while preventing angular movement of the rocker. It should be noted that the protrusions 72 and 73 project from the angular surfaces of the body which form the fulcrum 71.
  • the rocker 70 When the rocker 70 is placed within the recess of the pump base, it will not naturally assume a position other than tilted fully in one direction or the other because of the tapered seats 41 and 42 and the fulcrum 71. Only a force applied perpendicular to horizontal at the apex of cam surface 74 will allow the rocker to assume a totally horizontal position where neither of the protrusions 72 or 73 are fully seated within openings 41 or 42. To revent the rocker from being held in this horizontal position, or to allow the rocker to assume only itstwo stable states, thereby being purely bi-stable, the actuator 37 has the conical head 38 which continuously engages angular cam surface 74 because of the action of biasing member 39.
  • cam surface 74 and actuator head 38 both form angular surfaces, the two members when forced together cannot assume a stable statewith their respective apexes mating. Consequently, the conical head 38 must rest on one side of the apex of cam surface 74 or the other. Thus, the interaction of the spring biased actuator against the rocker 70 provides a truly bi-stable valve switching mechanism.
  • FIG. 6 shows the pump button 20 surrounding the pump housing 30 when the pump button is in the fully down position of the pump action.
  • valve of the present invention is truly bi-stable, having its stable position selected by lateral movement of the pump handle or button by the ironer using a single finger.
  • the present bi-stable valve is a combined pump housing reduces the number of movable parts and also the number of individual'selectors and dials that the user must actuate during the operation of the iron.
  • FIG. 5 shows the combination filter and check valve 25 which is received on coupling 65 at the end of tube 21.
  • the combination filter and check valve has a housing with a bottom 89 which is adjacent the bottom of the reservoir 18. Parallel to the bottom 89 is a bore extending diametrically-through the housing 80.
  • bore 85 at the bottom of the housing 80 allows for all the water in the reservoir to be received within the filter-check valve for use in the moisture systems of the present iron.
  • Communicating with horizontal bore 85 is a vertical bore 84 which communicates with the seat 82 of the check valve formed by an inclined surface narrowing the diameter of major bore 81.
  • a sphere 83 is contained within bore 81 and is received at seat 82 to seal bore 84. Functioning as a check valve, an upward force draws sphere 83 up and allows water to be drawn up through bore 81 into tube 21. Upon a downward pressure, the ball 83 is seated in seat 82 and seals bore 84 to prevent water from reentering the reservoir through horizontal bore 85.
  • One of the novel features of the present combination check valve and filter is the use of a spiral wire 88 surrounding the body of the check valve 80 for preventing debris in the reservoir from entering the check valve and the follow-on system including the pump housing.
  • the wire coil has a plurality of turns wherein the top turn 87 is received within notch 86 of the check valve housing 80.
  • the spiral wire has smaller or tighter turns at the top and thus tapered assumes a substantially constant diameter later on which is displaced and parallel to the body 80.
  • the spring rests on bottom 89 of the check valve body 80.
  • the space between the spiral elements 88 is sufficient to allow water to enter horizontal bore 85, yet small enough to prevent large pieces of debris from entering the check valve.
  • the present combination filter and check valve 25 may be replaced by standard filters and check valves and check valve 26 and valve cap 53 may also be replaced by standard check valves. Though those three mentioned check valves may be replaced by standard check valves, they provide three novel approaches to inexpensive and effective check valves which have a function other than merely regulating the flow, thus reducing the number of parts and the amount of space needed.
  • the present steam-spray iron provides four modes of operation. These modes are dry, constant steam, atomized spray, and high velocity steam.
  • the inventive combination pump and bistable valve of the present invention allows for selection between the atomized spray and the high velocity steam by mere lateral movement of the pump handle or button.
