Definitions

  • the present invention relates to an infuser unit in accordance with the precharacterising part of claim 1.
  • An object of the invention is to provide an infuser unit for beverage powders which is simple, versatile and interchangeable with the maximum simplicity and safety.
  • the invention revolutionizes the structural concept of automatic units for beverage powder infusions, by virtue of its versatility, simplicity and interchangeabil ity.
  • the infusion chamber of the infuser unit for which a patent is requested can be easily replaced with a differently personalized one, so substantially reducing the cost involved in selecting a new format for the sachet, capsule or the like. If using an infuser unit, only said unit has to be replaced rather than the entire machine, when the shape of the infusion chamber needs to be changed.
  • FIGS 1 and 2 are perspective schematic views taken from two different angles, of an infuser unit according to the invention.
  • Figure 3 is a schematic view thereof from above
  • Figures 4, 5, 6, 7, 9, 10 are perspective schematic side views thereof with a lateral shoulder removed, and shown in different operating positions,
  • Figure 8 is a view thereof as in Figure 7, but with the lateral shoulder replaced,
  • FIGS 11, 12, 13 are perspective schematic side views thereof with certain parts removed, shown in different operating positions,
  • Figures 14, 15, 16 are schematic side views of a first component thereof
  • Figures 17, 18 are longitudinal schematic sections through the component of Figures 14-16, shown without an expel ler ( Figure 17) and with said expel ler ( Figure 18) respectively,
  • Figure 19 is a longitudinal schematic section through a variant of the component shown in Figures 14-18,
  • Figures 20, 21, 22 are schematic side views of the expeller shown in Figure 18.
  • Figure 1 shows a first side of the infuser unit, comprising an infuser body 21 which rotates on the pivot 83, and a single-acting hydraulic piston 23 presenting an inlet and outlet for pressurized water. This is fed in by an electrically driven pump, not shown.
  • the piston return is achieved by springs 24A and 24B supported by the rods 25A, 25B.
  • the hydraulic piston is the drive member for the mechanical part of the unit.
  • the shoulder 27 of the sidepiece of the infuser unit is fixed to the jacket of the piston 23 and to the rotation pivot 83 of the infuser body 21.
  • the shoulder of the other sidepiece of the unit presents holes 28 for fixing the unit to an internal wall of the housing of the machine using the unit.
  • a closure element 22 for the infusion chamber 20A comprising a conduit for passage of the infusion water leaving through the holes 30A or 30B.
  • Figure 2 illustrates the infuser unit from the opposite side to that of Figure 1 and shows the shoulder 26 with the fixing holes 28 and 29, the shoulder 26 also being fixed to the piston 23.
  • Figure 3 shows the infuser unit from above, and in particular the body 21, the infusion chamber 20A, the infusion exit conduit 30A, and the rotation fulcrum fixed to the shoulder 27.
  • Figure 4 shows the infuser unit with the shoulder 26 transparent to highlight the arms 52 and 53 and the pivots for rotation of the infuser body 21.
  • Figures 5, 6, 7, 9 and 10 illustrate the mechanical cycle for a powder infusion.
  • Figure 5 shows the infuser unit at rest in the infusion chamber 20A. A packet of coffee or other infusion powder 60A is inserted before infusion.
  • Figure 6 shows the commencement of the cycle.
  • the pump not shown, is activated to feed water into the conduit 32 of the piston which, via the piston rod 70, thrusts forward the closure element 22 carrying the levers 52 and 53 pivoted thereto.
  • the lever 53 acts on the long pivots 41A and 41B, and by means of the thrust which it exerts on one of the pivots 41 causes the body 21 to rotate about the axis 31.
  • Figure 7 shows the infuser unit closed and ready for the infusion which takes place by the entry of water through the conduit 33, passage of the infusion product and its exit from the hole 30A. In this position the springs 24A and 24B are loaded.
  • Figure 8 is a repeat of Figure 7 but with the shoulder 26 not transparent.
  • Figure 9 shows the infuser unit during its return, the lever 52 hooking one of the short pivots 40A or 40B and rotating the body 21 in the same direction of rotation as the lever 53; during this stage the infusion powder residue 60B is discharged from the chamber 20A.
  • Figure 10 shows the infuser unit 21 again at rest but with the chamber 20B facing upwards instead of the chamber 20A, which now faces downwards.
  • Figures 11, 12 and 13 show the infuser unit with the shoulder 27 and body 21 transparent to highlight a rod 80, comprising discs 81A and 81B to expel the infusion residue.
  • Figure 11 shows the transparent infuser unit 21 during the loading of the infusion powder 60A; the rod 80 is shown with the disc 81A on the bottom of the infusion chamber 20A, whereas the disc 81B is on the outer profile of the infusion chamber 20B.
  • Figure 12 shows the infuser unit during infusion, at which stage the rod 80 has not changed its initial position.
  • Figure 13 shows the return of the infuser body to its rest position, with the rod 80 having inverted the positions of the discs: the disc 81B is at the top on the base of the infusion chamber 20B, whereas the disc 80A is on the outer profile of the infusion chamber 20A.
  • Figure 13 shows the inner face of the infuser body 21, the infusion exit 30A, the short pivot 40A for the return lever 52, not shown, and the long pivots 41A, 41B for the thrust lever 53, not shown.
  • Figure 15 shows the face of the body 21 seen from the side comprising the rotation pivots 40A, 41A, 40B, 41B; the through hole 90B for the rotation pivot and the infusion exit holes 30A, B can be seen.
  • Figure 16 shows the body 21 seen from the side comprising the cam 31, 85; the through hole 90A, B for the rotation pivot of the infuser body 21 and the aperture 91 for the rod 80 (not shown) can be seen.
  • Figure 17 is a section through the infuser body 21, comprising: the infusion chambers 20A, B, the aperture 91 for the rod 80, the through holes 90A, B for the rotation pivot, the conduit 30B for exit of the infusion from the chamber 20B, and the pivots 41A, 40B for the rotation of the body 21.
  • Figure 18 is equal to Figure 17, but presents inserts in the body 21, the rod 80 with the relative discs 81A and 81B, the arms 27 and 26 with the relative rotation pivot 83, and the cam 31 with pivot 85 for driving the rod 80.
  • Figure 19 is a section through a simpler variant of the infuser body 21, this being for infusion powders contained in those rigid containers, capsules, cartridges and other commercial types which do not require forced expulsion of the infusion residues; it comprises: an infusion chamber 20C, 20D, an exit 30B for the infusion from the chamber 20D and a through hole 90C for the rotation pivot of the body 21.
  • Figures 20, 21, 22 show the rod 80 with the discs 81A and 81B, the through recess 82 for the rotation pivot (not shown) and the cam 86 for the pivot 85 (not shown here, but shown in Figure 18).
  • the body 21 could comprise only one infusion chamber, or three or four or five or six chambers.
  • the means for rotating the body 21 could also be of automatic type different from those described, and comprise for example usual specific members for this movement, for example a motor.
  • the movement means could instead be of manual type.
