  • the present invention aims to remedy the drawbacks of the prior art and to allow the production at a low cost, of a steam generator which guarantees, with good efficiency, the production of steam free of water droplets, and facilitates descaling operations.
  • a steam generator of the type defined at the head of the description characterized in that the static means comprises a lining consisting of a set of calibrated metal balls in contact with each other. the others and in that the cavity has a dimension in the transverse direction between 1.1d and 2d, where d represents the diameter of the calibrated metal balls.
  • the lining of metal balls according to the present invention ensures both excellent concentration of heat, without risk of adhesion or clogging between the balls, and maximum division of the path of the water to be transformed into vapor. All the interstices between the balls can communicate with each other without a direct path being possible for the steam. Furthermore, the particular dimensioning of the cavity guarantees that at least half of the balls are in contact direct with the metal body in which the heating element is incorporated, which maintains a high temperature for all of the metal balls during operation and guarantees both a low time constant when the device is started up and steam production with good yield.
  • calibrated metal balls for example made of stainless steel, having a diameter of between approximately 2 and 5 mm.
  • a steam generator according to the invention only comprises static elements and can operate with a simple injection of water under pressure, without it being essential to spray it.

  • one of the first and second fittings is arranged laterally with respect to the cavity while the other of the first and second fittings is arranged axially in the vicinity of one of the ends of the cavity.
  • the cavity of the steam generator can advantageously have an elongated shape with rectangular section, with U-shaped section or even with annular section.
  • the operational safety of the steam generator can be further improved, in particular for appliances for general public use, thanks to a particular embodiment, in which the cavity comprises at least first and second separate elementary cavities which extend in the vicinity of the heating element and are placed in communication at one of their ends to define vaporization chambers operating in series.
  • the first and second connections are arranged in the vicinity of the same front face of the generator, the first connection opens in the vicinity of a first axial end of the first elementary cavity, the second connector opens in the vicinity of a first axial end of the second elementary cavity located near said first axial end of the first elementary cavity, and the first and second elementary cavities are in communication with each other by a channel communication disposed in the vicinity of second axial ends of said first and second elementary cavities.

  • the invention relates to an instant steam generator which can find a wide variety of applications, for example, and in a nonlimiting manner, in irons or steam ironing presses, wallpaper peelers, devices for removing fatty substances for fabrics. , steam cooking appliances, vending machines for hot drinks.
  • a steam generator 10 which comprises a metal body 11, 18 in which is formed an elongated cavity 12, whose shape is of revolution and defined essentially by two walls cylindrical coaxial of the body 11, 18.
  • the body 11, 18 can be produced using, on the one hand, a central metallic body of revolution 18, which can be produced by molding and having a central portion of reduced section to define the internal wall of the cavity 12, and on the other hand an external tube 11 which is attached around the central body 18 to form the external wall of the cavity 12.
  • O-rings 18A, 18B are interposed between the central body 18 and the outer tube 11 to seal the cavity 12 relative to the outside.
  • Tubes constituting connections 15 and 16 can be attached directly to the outer tube 11 and communicate with the cavity 12 by annular portions of section smaller than that of the cavity 12.
  • the outer tube 11 can be metallic or, if necessary, made of plastic.
  • An electrical resistance 14 which can be constituted by a standard central rectilinear element on which the central body 18 is overmolded, ensures the heating of the central body 18 and thereby of the cavity 12.
  • the electrical resistance 14 can have a power by example of the order of 1000 to 2000 watts. Its length can be for example between 150 and 300 mm and its diameter can be for example from 6 to 7 mm.

  • the size of the balls 13 can be adapted to the applications and to the size of the generator 10.
  • balls 13 having a diameter between 2 and 5 mm are very suitable.
  • the balls 13 do not need to have a surface condition comparable to that of the balls for bearings for example, since these balls 13 only play a purely static role. Balls such as those used to polish the material, for example, are well suited.
  • the role of the balls 13 is crucial insofar as these ensure a high concentration of heat, unlike wired elements for example, and define a very long divided path with broken lines between the various interstices arranged in staggered rows, this which promotes heat exchange. Furthermore, the beads do not stick to each other like mineral particles for example.
  • connections 15, 16 can be provided with strainers to prevent the exit of the balls 13, or else elements in the form of a baffle or labyrinth as will be explained later with reference to particular examples of connections.
  • the dimension e of the annular cavity 12 in the radial direction is such that this dimension is between 1.1d and 2d where d represents the diameter of the calibrated balls 13.
  • d represents the diameter of the calibrated balls 13.
  • the balls 13 maintain a temperature sufficient to continue to play their role in heating the new water introduced and steam can continue to form, unlike in the case where the cavity has a larger section in which the path is longer between the heating body and the balls furthest from this heating body.
  • the transverse dimension e of the cavity 12 must be sufficient to allow the introduction of the balls 13 with play, but must remain less than twice the diameter of the balls to prevent more than two balls from being interposed between the central body 18 and the tube external 11.
  • the transverse dimension j of the grooves formed in the central body 18 at the connections 15, 16 must itself remain smaller than the diameter d of the balls 13 to prevent them from escaping through the connections 15, 16.
  • FIGS. 1 and 2 The embodiment of Figures 1 and 2 is particularly simple to perform, but can be the subject of many variants.
  • Figure 3 we have shown an annular cavity 12 divided into two elementary cavities 12A, 12B by longitudinal partitions 19 oriented along a radius and connecting the central body 18 to the outer tube 11.

  • the connections 15, 16 for introducing water and for discharging steam are located in the vicinity of a first front face of the steam generator, the connection 15 serving for the introduction of water into the cavity 121 and the connector 16 used for extracting steam from the cavity 122.

  • Figures 7 and 8 show another possible embodiment in which the metal body 11 is made in one piece by overmolding the heating resistor 14 in a U shape placed in a median axial plane of the cavity 12, around that -this.
  • the cavity 12, which has a flattened rectangular section, is lined with balls as in all the embodiments previously described, and the small dimension e of the rectangular section of the cavity 12 has a value between 1.1d and 2d where d represents the diameter of the balls.
  • the connector 15 ′ comprises a nozzle 22 defining a blind central channel 23 which opens out through one or more lateral orifices 29 in an annular groove 26 which communicates with the cavity 12 by a peripheral annular passage 28 of width less than the diameter of the balls 13 (for example having a width of the order of 1.5 mm if the biles have a diameter of 2 mm) .
