Definitions

  • Piston-type and bellows-type pumps being entirely manually operated, are readily adapted to permit spraying during dry ironing.
  • the piston-type pumps present many disadvantages including the relatively high operating force required to overcome the friction between the piston seals and cylinder, and the short life of the moving piston seals.
  • a disadvantage of the bellows-type pump is that the severe flexing of the small radius of the convolutions introduces friction that must be over.- come by the manual operating force and also causes failure due to rupture.
  • sprayers utilizing spring-biased valve members add to the required force as the force of the spring must be overcome to dispense water through the valve.
  • I provide a steam iron having a diaphragm pump located in a handle support thereof.
  • the inlet to the pump communicates by means of an inlet tube with a water reservoir which is disposed beneath the pump within the cover of the iron.
  • a check valve is located in the inlet tube to permit the flow of water up into the pump but to prevent its flow back into the reservoir.
  • the outlet of the pump communicates with a sprayer designed to dif fuse any water expelled therethrough into a fine mist and particularly providing for easy maintenance and reduced pump operating force.
  • Operating means connect the diaphragm with a push button which is manually operable at the top of the handle to compress the diaphragm, thus expelling water through the sprayer.
  • a leaf spring is secured within the pump chamber having its free and disposed adjacent a ball-type inlet check valve. Upon compression of the diaphragm, the free end of the leaf spring is pressed against the ball of the check valve. This presses the ball against its valve seat to seat the ball firmly and to crush any foreign particles lodged between the ball and the valve seat.
  • FIG. 1 is a sectional elevation view of the forward section of a steam iron incorporating an embodiment of this invention
  • FIG. 2 is an exploded perspective view of the diaphragm pump of this invention
  • FIG. 3 is a perspective view of the operating means of the pump of this invention having portions thereof cut away for clarity, and
  • FIG. 4 is a sectional of this invention.
  • FIG. 1 shows, in section, the forward portion of a steam iron having a handle 10, a cover 11 and a soleplate 12.
  • a water reservoir 13 having a drip valve 14 in its bottom wall. Water within the reservoir may be dispensed through valve 14 onto the soleplate 12 to flash into steam when the soleplate is heated by heater 15.
  • a soleplate cover 16 is afiixed to the top of the soleplate and provides paths for the passage of steam from a boiler 17 to a plurality of steam outlets, one of which is shown at 18. Steam is ejected from the outlets onto the clothes being ironed.
  • this invention incorporates a diaphragm pump 20 mounted in forward hollow handle support 16a.
  • the diaphragm pump 20 communicates with reservoir 13 by means of a water or inlet tube 21 which extends vertically from a point adjacent the bottom of the reservoir through the top of the reservoir.
  • Any suitable unidirectional valve, such as ball-check valve 22 having a ball 23, may be used to connect the water tube 21 to diaphragm pump 20.
  • Sprayer 19 is secured to pump 20 and comprises a sprayer body 24, an apertured cap 25 threadedly engaged with body 24, a spreader 26, a spring 27 and a ball-check valve 28.
  • the spreader 26 insures an even flow of water elevation view of a modified form to aperture 25a of cap 25 and also aids in effecting the spraying by imparting a whirling action to the water through the provision of a plurality of grooves 26a.
  • the upper endof spring 27 limits the downward movement of the ball 29 and abuts surface or shoulder 34 to bias spreader 26 against the inner surface of cap 25.
  • Shoulder 30 is spacedfrom the seat of valve 28 so as to permit the free play of ball 2h between the valve seat and the upper end of spring 27.
  • spring 27' has a varying coil diameter to frictionally engage the inner surface of body24 at 31 and to frictionally engage a reduced portion 32 of spreader 26, thereby holding the spreader and spring 27 Within the sprayer body. This feature prevents the possible loss of sprayer elements resulting from their falling from the sprayer body when.
  • cap 25 is removed for cleaning.
  • Diaphragm pump 20 comprises a rigid brass shell 33,
  • the deflector 38 is secured by rivet 3% to the outer surface of the diaphragm and is part of thepump operating mechanism.
  • the periphery of deflector 38 is turned upwardly to conform with the configuration of shell 33 thereby being capable of closely compressing diaphragm 34 against the shell to maximize expulsion of-water from the pump.
  • the deflector 38 provides a relatively large flat center area and the diaphragm 34 is clamped between this flat area and a disk 49 by rivet 39. This insures positive movement of a relatively large center area of the diaphragm. It has been found that when a rubber diaphragm such as 34 is deflect d at its center, in the conventionalmanner of'deflecting metal diaphragms, the area between the center point and the periphery will bulge upwardly due to the fluid pressure.
  • a pump support 41 afl'ixed to reservoir 13, secures pump shell 33 in position in the forward end of handle support 16a.
  • a pair of tabs 42 are provided on the side edges of pump support 41, for engagement with lever bracket 43. Bracket 43 is secured by turning these tabs inwardly. This produces a rigid assembly of pumpsupport, pump and bracket, and
  • Deflector 33 is operated and supported by lever 44. A.
  • pin 45 passes through the arms 46 and 47 of lever 44 and through apertures 48 in the upstanding ears 38a of desecured to the vertical Walls 5% of bracket 43. Walls 50 also provide openings 51 Which accommodate-deflector 38.
  • a wire spring 52 is'secured about rod 49 and includes an arm 53 which engagesthe lower surface of pin 45. V V
  • the pump is actuated through a push button 54 which extends upwardly above thetop surface of handle 10 for operation by the user.
  • Push button. 54 is connected to lever 44 through any suitable means such as a rod 55.
  • diaphragm 34' has a normal first position in which it is flexed concavely away from shell 33 to form a pump chamber. To expel water from the chamber, diaphragm 34 is moved to a second position into abutment with shell 33.
  • Lever 44 is pivotal about rod 49 which. is t Toillustrate the operation of this invention, it will be assumed thatdiaphragm 34 is in its normal position pre-- pared to expel water present in the pump through sprayer- 19 onto the material being ironed'sAs the push button 5 is depressed, lever 44 pivots about rod 49 against the bias of spring 5?; to press deflector 38, and thusdiaphragin 34, to which the deflector 38 is secured, against shell 33. As mentioned above, the large area .of deflector 38 prevents any undue bulging of diaphragm 34 to maintain a steady flow of-water from the pump during the compression stroke.
  • deflector 38 assures conformity of diaphragm 34 tothe concave configuration of shell 33 and prevents sharp deflection of the diaphragm.
  • Water expelled from the pump 20 is directed through outlet 37, and past ball 25? so as to pass through sprayer 19, ball 23 meanwhile preventing the flow of water back into reservoir 18 through check. valve 22. p.
  • spring 52 Upon release of push button 54, spring 52 operates to return lever 44 and thus the entire operating mechanism as Well as diaphragm 34. to the normal position shown in FIG. 1. During the return ofdiaphragm 34 to its normal position, the normal pressure in reservoir 13 forces water up inlet tube 21, throughcheck valve 22 and into pump Ztkthe suction presentin the pump chamber causing ball 29 to seat against the valve seat of valve 28 to prevent the entrance of 'air therethrough.
  • this invention provides a simple, inexpensive mechanism of high: dependability which assures even Water spraying during either steam or dry ironing.
  • the diaphragm pump is more than other types due to its inherently low friction.
  • the location of the pump inthe handle support not only provides for more precise control of spraying being close to the handle-mounted push button,.but also reduces the likelihood of vaporization and the consequent poor operation resulting from location in the reservoir.
  • the sprayer mechanism insures retention ofthe elements thereof within thesprayer body upon removal ofthe cap for cleaning.
  • FIG. 4 reveals a modified embodiment of the diaphragm pump of my invention de'signedto minimize the dangers of accumulation of foreign particles in the pump inlet valve.
  • the pump includes a diaphragm 134, a rigid metal shell 133 having an inlet and an outlet, and a ball check valve 122, similar to that, of the pump discussed above. Additionally, however, the modification of FIG. 4 embodies a leaf spring ldtl'which is secured to the inner surface of the shell 133 and providesa free end 161 which is normally disposed immediately above the -ball 123 of ball check valve 122.
