Definitions

  • the currently known boilers for producing steam to be supplied to irons consist of a heated container with a cap for topping up the water content when the quantity of water previously introduced inside the boiler is about to run out. This results, among other things, in:
  • the apparatus with a boiler for producing steam intended for an iron, a steam cleaner or the like substantially comprises a moving member on which the boiler is mounted and which is raised and lowered depending on the variation in weight of the boiling water inside the boiler, and a control system which is based on the displacements of said moving member and which controls the supply of limited quantities of water to the boiler.
  • the said moving member is supported by at least one resilient element and more particularly said moving member may be hinged on a horizontal axis and supported by at least one spring at a distance from said axis.
  • the apparatus comprises an electric pump for supplying the water to the boiler and a switch, in particular a microswitch, which is actuated by the displacement of the said moving member and which operates the said electric pump.
  • both the pipe supplying the steam from the boiler and the delivery pipe of the pump for supplying the water to the boiler have a deformable section; advantageously said deformable sections extend adjacent and parallel to the said hinging axis of the moving member.
  • a fixed tank 1 is connected by means of a draw-off pipe 2 to an electric pump 3 which forces the water through a supply pipe 4 into the boiler 5 heated by the resistor 6.
  • the boiler is mounted on a moving member 7 which is joined to a surface 8 - on which the tank 1 is situated - by means of a hinge 9 with a horizontal axis; said moving member 7 is supported by a spring 10.
  • the moving member 7 compresses the spring 10 on which it rests and is thus lowered until it acts on a switch 11, which interrupts operation of the pump 3, interrupting the introduction of water into the boiler.
  • the temperature of the boiler is controlled by a thermostat 14.
  • the boiler is provided with at least one pressure-regulating valve 13 which will allow the steam to escape from the boiler in the event of excessive pressure inside the boiler itself.
  • the water tank 23 is located in a fixed manner on a base 21; a lid 23A allows periodic filling of this tank 23, independently of the frequency with which the boiler is supplied for generation of the steam.
  • a moving member 27 which comprises in particular also the boiler 29; at a distance from the hinging axis 25, this moving member 27 rests on a spring 31 so that, with the variation in the load of the moving member 27 comprising the boiler 29, it is possible to obtain a variation in the compression of the spring and hence gradual raising of the moving member itself as water inside the boiler 29 is used up for the production of steam supplied to the iron.
  • the pipe 33 denotes the pipe for conveying the steam from the boiler 29 to the iron (not shown); said pipe 33 is flexible and the section 33A thereof extends in the vicinity of the hinging axis 25 and parallel to this oscillation axis so that the movement of the moving member 27 about the axis 25 produces only a very small torsional deformation of the said section 33A of the pipe 33.
  • 35 denotes a solenoid valve for effecting removal of the steam from the boiler; said solenoid valve 35 is controlled by a pushbutton or other operating member which is present in the iron; thus the user is able to request a supply of steam, as required, by operating said pushbutton or the like using the same hand with which the iron is gripped.
  • the water is supplied from the tank 23 to the boiler 29 via a pipe 37 which reaches an electric pump 39.
  • a delivery pipe 41 extends from the pump 39, said delivery pipe being flexible and extending with a section 41A in the vicinity of and approximately parallel to the axis of rotation 25, so that this pipe 41 also undergoes a very limited degree of torsional deformation with the movement of the moving member 27 of the boiler 29 about the axis 25.
  • 43 denotes a return pipe from the pump 39 towards the tank 23, allowing the flowback of pumped water exceeding the predefined throughput for supply of the boiler itself.
  • a bracket 27A forming part of the moving member 27 and positioned at a distance from the hinging axis 25, is used for resting on the spring 31 and for acting on the actuating arm 45A of a microswitch 45 which controls the motor of the electric pump 39.
  • FIG. 29A denotes the heat source - for example an electric resistor - which serves to generate the steam inside the boiler 29.
  • This heat generator is controlled by a pressure switch and/or a thermostat, as mentioned above.
  • the moving member 27 As the quantity of boiling water contained in the boiler is reduced owing to the generation of the steam supplied (via 33 and 33A) to the iron, the moving member 27 is gradually raised by the spring 31 until raising of the moving member 27 is such that it triggers, via the microswitch 45, operation of the pump 39 so as to allow a desired and limited quantity of cold water to be introduced from the tank to the boiler 29; this quantity of pumped water is limited with respect to the residual quantity of water which is already boiling, so that there is practically no variation in the capacity of the boiler to deliver steam to the iron.
