Definitions

  • the present invention relates to beverage dispensers preparing beverages from a beverage ingredient stored in a container and from which a dose of beverage ingredient is dispensed into a beverage preparation chamber to be mixed with a diluent.
  • beverage powder is usually stored in a tank or canister provided with a dosing device in order to deliver a dose of beverage powder in a mixing chamber supplied with a diluent, usually hot water.
  • the tank or canister of powder is usually placed above top opened mouth of the mixing chamber and a dosing device like a screw, a drawer or an auger doses and delivers the powder which falls in the chamber.
  • a dosing device like a screw, a drawer or an auger doses and delivers the powder which falls in the chamber.
  • extractor hood at the top of the chamber and to connect it to an evacuation fan in order to suck steam and powder fines flying above the chamber during the beverage preparation.
  • the extractor hood avoids that steam flows up to the powder dosing device and the powder tank which would lead to a caking of the powder in these devices.
  • the extractor hood avoids that fines of powder fly in the internal housing of the beverage preparation machine too.
  • extractor hoods usually simply consist in an air sucking opening above the mixing chamber, and as a result, there is no real control of the path for air above the chamber.
  • extractor hoods are usually used with a powerful fan to guarantee that humidity is sucked, but the powerful generated flow of air sucks humidity and powder indifferently. It becomes necessary to provide a trap for powder and to regularly clean said trap or the machine to remove sucked powder therefrom.
  • Another solution consists in blowing air inside the chamber along the direction of fall of the powder in the chamber and then preventing mist and humidity from rising through the top of the chamber like in US 4,194,651 or US 2,755,000. Yet the machines implementing this solution are not compact because they require additional vertical place to orient the flow of air inside the mixing chamber.
  • EP 2 000 065 solved this drawback and proposed to guide air across the inlet opening of the chamber and perpendicularly to the center axis of the inlet opening to generate a venture effect sucking off steam or other humidity from the chamber.
  • the device comprises a controller synchronizing the operation of the air blowing means and the operation of the dosing device such that the blowing means are not active when the dosing device allows an ingredient dose drop in the mixing chamber.
  • a drawback of this solution is that the operation of the air blowing means - either activation or stopping - presents a certain inertia.
  • the controller has deactivated the air blowing means, usually a fan, a flow of air still moves in the air conduit that leads to the top opening of the chamber.
  • the controller has deactivated the air blowing means, usually a fan, a flow of air still moves in the air conduit that leads to the top opening of the chamber.
  • a part of the powder being dosed is blown by air before it reaches the chamber.
  • This part of the powder is carried by the remaining flow of air downstream in the air conduit and dirties the internal parts of the machine.
  • the complete dose of powder does not reach the powder inlet, and dosing is inconsistent, and powder dirties the machine.
