Definitions

  • the present invention relates to devices for hot beverage machines in particular coffee machines. It is a back pressure device that can be applied to doses of powdered material, namely capsules, lozenges, or single portions of coffee, regardless of their shape.
  • US 2006/0196362 also describes a capsule-extracting espresso machine, and its innovative aspect is a bypass line that is used only when the pressure reaches a set value by controlling the mixture of coffee-water. The user can set the coffee-water mixture pressure.
  • GB 2451692 relates to a filter assembly for an espresso machine. While this patent teaches a method of controlling presser overpressure over a filter containing ground coffee (no capsule is described), this is done by a retracting mechanism of the filter holder and therefore it is a mechanism substantially different from that disclosed in the invention of this patent application.

  • the present invention relates to hot beverage machines in particular coffee machines. It is a device with back pressure system.
  • This back pressure device according to the invention is independent, and can be coupled to any heating source, whether thermo-blocks, boilers, etc. It does not separate water, uses the same water to lower the system as well as to extract coffee, which makes it very simplified in its assembly. Its components are easy to assemble which makes it profitable and optimizes your manufacturing process.
  • the back pressure device of the invention allows for easy adaptation (without changing the assembly) to any capsule size by simply adjusting the presser foot stroke of the capsules, lozenges or a single portion of coffee. This device also allows the extraction of coffee grounds after use by simply using the corresponding accessory, the holder (16).
  • Figure 1 is a cross-sectional view of the restraint device in rest position.
  • This device consists of an extraction plate (1), a presser foot (2), a plunger (3), a presser foot (4) (2), a compression spring (5), an extraction plate holder (6), a distribution cap (7), a check valve (8), a preferably conical spring (9), a check valve (10), a check valve spring (11), a water valve bushing (12), at least one seal, preferably four o-rings (13 ), a dose holder accessory (capsule holder, tablet holder, or filter holder) which may be adapted for capsules (15) for tablets (17) or single portions of coffee.
  • the presser foot (2) and the cover (4) of the presser foot (2) are two solid and movable parts.

  • Figure 3 shows the section through the water outlet in the back pressure device, which is in the loading position with a coffee tablet (17).
  • capsule size (15) or insert holder (16) minus the desired stroke After introducing the capsule (15) or the insert holder (16) in the center of the back pressure mechanism, by mechanical movement, it causes upward pressure on the presser foot (2), which is a movable component, thus causing it to move. axial sliding by the piston (3). This presser foot then back-presses the compression spring (5) and it in turn puts downward pressure on the presser foot (2). This back pressure causes the capsule (15) or insert holder (16) to clamp.
  • the pump is started and causes the solenoid valve to close, sucks the water out of the water tank, then pressurizes it to a heating source.
  • This heated water flows to the back pressure device through water pipes.
  • Hot water enters the upper bore (18) of the distributor cap (7), under pressure it causes the check valve (8) to open, and it allows hot water to circulate in the water circuit of the back pressure device.
  • the required pressure to open the check valve (10) is reached allowing water to pass through the holes in the water valve bushing (12). Coffee is then extracted when water passes through the capsule or tablet under pressure.

Abstract

L'invention concerne un dispositif d'extraction destiné à une machine de préparation d'infusions à partir de doses d'une matière en poudre, et trouvant notamment une application dans les machines à café expresso. Ce dispositif comprend une plaque d'extraction (1), par exemple pour capsules, pastilles ou portions individuelles de café, les doses pouvant être traversées par de l'eau chaude sous pression en vue de la préparation de boissons d'infusion, et comprend en outre un presse-mouture (2), un piston (3), un couvercle (4) du presse-mouture (2), un ressort de compression (5), un support (6) de la plaque d'extraction, un couvercle de distribution (7), des valves de retenue (8, 10), et une douille (12) de la valve de régulation d'eau. Après introduction de la capsule de café (15) au centre du mécanisme de contre-pression, le presse-mouture exerce une pression sur le ressort de compression (5), lequel, à son tour, exerce une contre-pression descendante sur le presse-mouture (2), permettant ainsi la fixation de la capsule (15) sur la plaque d'extraction (1).
