Definitions

  • the subject of the present invention is a steam generator with direct evaporation, without accumulation of pressurized steam, comprising a first plate provided with at least one channel for supplying a pressurized fluid to be evaporated, a second plate, independent of the first plate and superimposed on the latter, a vapor recovery cavity in communication with a peripheral part of the first and second plates, and an electrical heating resistance located at least approximately in a plane parallel to said first and second plates.
  • the aforementioned steam generator can perform its function of instantaneous production of steam effectively with a low space-saving and without the use of pressurized steam storage assemblies.
  • this type of steam generator of the prior art has drawbacks due in particular to the problems posed by scaling, in particular at the level of the sprayer responsible for spraying water on the evaporation surface.
  • the present invention aims precisely to remedy the aforementioned drawbacks and in particular to produce a direct evaporation steam generator whose structure is simple and inexpensive to build while overcoming the faults of the steam generators of the prior art linked to lime deposits .
  • the channel for supplying pressurized fluid opens freely from the first plate perpendicularly to the latter and to the second plate, in a central part of the generator, and has an outlet diameter greater than about 2.5 mm, and the face of the second plate situated opposite the first plate is kept pressed against the face of the first plate by elastic return means.
  • the upper face of that of the first and second plates located in the lower part is provided with a set of concentric grooves.
  • the concentric grooves formed delimit several closed concentric circuits without communication between them.
  • Said concentric grooves may have a U-shaped section.
  • said concentric grooves have an asymmetrical section and include walls whose slope is less on the side closest to the fluid supply than on the opposite side.
  • the concentric grooves comprise a progressive downward recess produced from the side closest to the fluid supply and having a lower face comprising a convex surface of large radius of curvature followed by a concave surface of small radius of curvature, while a shallow groove is formed in the underside of that of the first and second plates located in the high position at least in the part opposite the parts of concentric grooves of slight slope to form a clear recess .
  • the tray provided with grooves prefferably have symmetry with respect to two rectangular axes, the intersection of which is situated at the level of the zone which faces the orifice for supplying the fluid to be evaporated.
  • the electric heating element is integrated in the first fixed plate.
  • the lower face of that of the first and second plates located in the high position constitutes an evaporation surface which cooperates with the evaporation surface formed by the upper face of the lower plate.
  • the underside of the upper plate is perfectly smooth.
  • the steam generator according to the invention is universal and can be adapted to a large number of applications requiring the production of steam at low cost with severe conditions of reliability and operational safety. Application to irons or ironing presses is particularly advantageous.
  • a steam generator comprising a fixed upper plate 39, in which is incorporated a heating resistor 56, a lower plate or movable counter plate 58 supported by means of springs 59 on a base 55 constituted for example by the sole of an ironing press.
  • the upper plate 39 (FIGS. 1 and 3) comprises a peripheral flange 53 which rests on the sole 55 and is fixed to the latter by means of connecting elements 54.
  • a peripheral cavity 60 for recovering steam is formed in the plate upper 39 to collect the vapor formed in contact with the lower face 139 of the upper heating plate 39 and of the upper face 158, of the counter plate 58, when pressurized water feeds the central channel 40 formed in the upper plate 39
  • the peripheral cavity 60 of the upper plate 39 is itself in communication by an annular slot of small width with a vapor distribution chamber 61 constituted by the free space included between the lower face of the counter plate and the sole 55.
  • the counter-plate 58 is permanently applied against the upper plate 39 by means of the springs 59 which are engaged in housings 52 formed in the peripheral part of the counter-plate 58.
  • the peripheral cavity 60 allows sufficient space to be provided between the external rim of the upper plate 39 which ends in the lower support rim 53 and the main mass of the plate 39 heated by the resistor 56. Indeed, the plate 39 is subjected deformations due to temperature variations.
  • the peripheral groove 60 precisely allows deformations to be absorbed without the lower surface 139 of the plate 39 being itself affected, and also makes it possible to reduce thermal bridges.
  • the peripheral cavity 60 constitutes a free volume where the vapor coming from the limited space between the plates 39 and 58 can relax and consequently guarantee that even the residual water particles are well evaporated.
  • the lower plate preferably projects a little beyond the rim 239 constituting the peripheral part of the main heating part of the plate 39.
  • the lower plate 58 is in fact subjected to slightly less stresses than those to which the upper plate 39 is subjected.
  • the presence of a peripheral slot 64 of relatively reduced width between the plate 58 and the external support rim of the plate 39 allows easier centering of the movable lower plate 58 while constituting a new barrier for drops of water. Any water which, due to capillarity cannot pass from the peripheral cavity 60 to the distribution chamber 61.
  • the distribution chamber 61 is not essential for all applications.
  • the steam could be captured in a pipe opening into the recovery cavity 60 (see FIG. 10).
  • the electric heating resistor 56 can be constituted by an armored resistor arranged for example in a spiral (FIG. 3), and situated essentially in a plane parallel to the contact plane between the faces 139 and 158 of the plates 39 and 58 respectively, which contact plane is itself parallel to the sole 55.
  • the upper plate 39 constitutes a heating plate in which the heat is almost uniformly distributed. This arrangement is advantageous for safety because the electrical resistance is placed outside the water and steam circulation zones.
  • the pressurized fluid supply channel 40 to be evaporated may comprise (FIG. 5) a first section (140) of relatively large section to facilitate connection to a liquid supply pipe, which can moreover come from a tank located in the immediate vicinity of the steam generator, and sections 141, 142 of smaller section in the vicinity of the outlet of the channel, the different sections being able to correspond to standard type fittings.
  • a first section (140) of relatively large section to facilitate connection to a liquid supply pipe, which can moreover come from a tank located in the immediate vicinity of the steam generator, and sections 141, 142 of smaller section in the vicinity of the outlet of the channel, the different sections being able to correspond to standard type fittings.
  • the smallest section 142 of the channel 40 does not have too small dimensions in order to eliminate any risk of scaling and to facilitate the operation of the system. It is thus essential that the liquid can flow freely at the outlet of the conduit 40. Consequently, no sprayer or other device must be added to the conduit 40.
  • the duct 40 has at all points a cross section greater than about 2.5 mm and may for example have an outlet section close to 4 mm at the level of the section 142, or generally a section quite close that of the liquid supply pipes.
  • the upper face 158 of the counter plate 58 (FIG. 2) is advantageously provided with a series of concentric grooves 62 and each forming a closed circuit.
  • the grooves 62 have the purpose of both trapping the drops of water which has not evaporated in order to prevent these drops from moving towards the periphery of the counter-plate 58 and entering the vapor-receiving cavity, and ensure a uniform distribution of the vapor and the film of water to be evaporated over the entire surface 158 of the counter plate 58.
  • the plates 39 and 58 and the grooves 62 advantageously have a symmetry by with respect to two rectangular axes substantially intersecting at the level of the part facing the outlet orifice 142 of the fluid supply channel 40.
  • each plate can comprise an elongated rectangular central part extended at its two lateral ends by half-discs.
  • the grooves 62 advantageously have two rectilinear parts 162 (FIG. 2) parallel to the longitudinal axis of the plate 58, and two circular end portions 262 whose center of curvature coincides with the center of curvature of a rounded end portion of the tray 58 itself. This configuration ensures a very good distribution of the vapor and therefore of the pressure from the center 258 of the plate 58 to the periphery thereof which is in the vicinity of the cavity 60.
  • the absence of radial grooves connecting the various grooves 62 together ensures retention of the non-vaporized water drops. It should be noted that the water arriving through the channel 40 is truly crushed in the form of a thin film between the plates 39 and 58. This crushing occurs regardless of even the possible scaling of the surfaces 139 and 158, since the spacing between these surfaces is not fixed, but is conditioned on the one hand, by the force exerted by the springs 59 to apply the plate 58 against the heating body 39 and, on the other hand, by the pressure of the liquid arriving through the channel 40, which liquid tends to move the plate 58 very slightly apart to allow the passage of a thin film of liquid between the two surfaces 139 and 158, which film is then transformed almost instantaneously into vapor in contact with the hot walls 139 and 158.
  • the lower plate 58 always remains in the immediate vicinity of the upper heating plate 39 and, during intermittent operation, even has its upper face 158 pressed against the lower heating plate 139 of the plate 39, since no pressure no liquid opposes the action of the springs 59. The face 158 is then heated very effectively.
  • the face 139 of the upper plate 39 is perfectly smooth. However, in certain cases, and in particular for particular configurations of the plates, certain grooves can be provided in the wall 139 of the plate 39.
  • Figures 5 and 6 show alternative embodiments of elongated lower trays 58 which include additional means to facilitate the distribution of the steam in the longitudinal direction. It will be noted that the means used in FIGS. 5 and 6, or equivalent means, can be used each time the steam generator has plates 39 and 58 which are not of revolution around the axis of the orifice. fluid supply. In this case, in fact, unlike in the case of FIG. 7, the distribution of the steam could be made more difficult in the directions of larger dimensions of the plates.
  • the tray 58 there is arranged in addition to a group of concentric grooves 362, 662 centered on the zone 258 located opposite the orifice fluid outlet, rectilinear grooves 462 extending along the longitudinal axis of the plate 58 and in communication with the groove 362 closest to the zone 258.
  • the radial grooves 462 terminate at a distance from the first concentric groove 662 surrounding the central annular groove 362, in order to avoid any communication between two neighboring concentric grooves.
  • the number of radial grooves and closed concentric grooves can naturally vary depending on the applications and especially the dimensions of the plate 58.
  • steam outlet orifices 63 are formed in the vicinity of the peripheral parity of the plate 58, and preferably at the center of curvature of the rounded parts of the plate. These orifices are in communication with a part of the chamber 61 of FIG. 1, which chamber then constitutes with the peripheral cavity 60 a vapor recovery zone. In fact, the steam can always be evacuated through the peripheral part of the tray 58. However, the additional steam outlet orifices contribute to creating a vapor call which facilitates the transfer of the latter along the longitudinal axis of the tray 58.
  • annular grooves 562 are formed around the orifices 63.
  • One or more peripheral grooves 662 are formed on the tray 58 in the manner described above in order to trap water during the evacuation of steam at the outer edge of the tray 58.
  • the grooves 62 can have various shapes depending on the applications envisaged.
  • a U-shaped section, as shown in Figure 1, is very easy to make.
  • a profile corresponding to that shown in Figure 4 is also advantageous.
  • this shape of groove 62 comprises a gradual step 162 from the side of the groove closest to the zone 258 for introducing the liquid onto the plate 58, then a second part of a stiffer wall on the opposite side of the groove.
  • the first wall part 162 can thus be slightly convex with a large radius of curvature, while after an inflection point constituting the bottom of the groove, the wall part opposite to the first part 162 is stiffer and concave.
  • the upper face 139 of the upper plate 39 can in this case comprise a groove 144 of shallow depth, at least in the part opposite the groove part 162 in order to constitute a sudden detachment which prevents drops of water from s' attach to the top wall.
  • the sole 55 which constitutes the bottom of the steam chamber 61 in the case of an application to an iron or an ironing press can conventionally comprise passage holes for the steam. However, for a better distribution of the vapor, it is preferable that these passage holes do not emerge punctually on the underside of the soleplate 55, but in narrow grooves 57 ( Figures 1 and 3) which mark the laundry less to redo.
  • an upper heating plate which incorporates a pressurized liquid supply channel cooperates with a lower plate applied by means of springs against the lower face of the upper plate which constitutes one of the two evaporation surfaces.
  • the presence of grooves in the lower plate as well as the creation of a smooth evaporation surface cooperating with at least corresponding smooth parts of the lower plate also constitute important characteristics.
  • the upper plate 39 and at least part of the sole 55, the relative positions of which are fixed can be produced in one piece by foundry molding.
  • the counter-plate 58 can in this case be introduced from below, during assembly, through a removable central part of the sole 55.
  • FIG. 8 precisely shows an alternative embodiment of the generator of FIG. 1 in which the upper plate 39, its outer rim and its lower bearing rim 53 are mounted in one piece with a part 55b forming the sole, in particular for a application to an iron or ironing press.
  • the sole 55 is then constituted by a peripheral part 55b and a central part 55a attached by connection means 54 on the plate 39 and placed in alignment with the part 55b.
  • This embodiment makes it possible in particular to introduce or remove the plate 58 from below by simply removing the plate 55a, which can be of small thickness. As can be seen in FIGS.
  • the part 55b of the sole may include stiffening ribs 55c which at the same time serve as steam distribution slots in the case where the slots 57 of the ribs 55c are in communication with the chamber 61. It will be noted that the embodiment of FIGS. 8 and 9 ensures perfect vapor tightness in the upper part. Indeed, the upper plate 39 and its peripheral parts 53, 55b constitute a tight cover so that all the vapor formed can escape only from below the sole 55.
  • the faces 139 and 158 (except the presence of grooves 62) of the plates 39 and 58 are preferably flat.
  • these faces 139 and 158 could also have a slightly convex shape, for example spherical or cylindrical with the same relatively large radius of curvature, the faces 139 and 158 therefore being always complementary to each other.
  • FIG. 10 shows another embodiment of the steam generator according to the present invention.
  • the heating plate 39a is arranged under the movable plate 58a, but the operation remains the same insofar as the evaporation of the water introduced by the central channel 40a formed in the heating plate 39a, always occurs in contact with the faces 139a and 158a respectively of the plates 39a and 58a, which faces 139a and 158a are located opposite one another and are applied one against the other under the action of the springs 59a which exert downward pressure on the plate 58a.
  • a heating resistor 56a is incorporated in the plate 39a and is located, as in the previous embodiments, situated in a plane substantially parallel to the evaporation surfaces 139a and 158a.
  • the pressurized fluid supply channel 40a preferably opens into a recess 143, which makes it possible to use, for the supply of fluid in the channel 40a, only relatively modest pressures obtained with small pumps in common use ensuring that at the level of the recess 143, the pressure exerted by the fluid well counterbalances that exerted by the springs 59a so as to provide the thin passage necessary for the film of fluid to be evaporated between the surfaces 139a and 158a.
  • the grooves 62a similar to the grooves 62 are formed in the lower plate which is then the fixed plate 39a.
  • the steam which escapes at the periphery of the plates 39a and 58a is collected in the peripheral cavity 60a and can be evacuated by the conduit 61a situated at the upper part of the steam generator.
  • the upper outer casing 155 on which the springs 59a bear, is made integral with the lower plate 39a, for example by connection means 54a.
  • the generator of Figure 10 could like the previous embodiments be applied to an ironing press, and be for example incorporated into the lower plate.
  • This generator for instantaneous steam production is also particularly suitable for constituting an independent element which can be incorporated into devices such as wallpaper strippers for example.
