Definitions

  • the enhanced refrigerating carbonator for drinks of the present invention is of the type provided with a sealed container comprising:
  • known carbonators of this kind are supplied with water to be carbonated, by means of a pump connected to said first inlet of the container of the carbonator and controlled by the level sensors, able to determine the appropriate quantity thereof to be introduced.
  • the water is normally injected through a nozzle that causes its nebulisation.
  • CO 2 gas carbon monoxide
  • the container of the carbonator is thus under pressure and it must therefore be maintained strictly sealed.
  • any electrically driven agitator to prevent any short circuit hazard.
  • the agitator is constituted by a simple external pump, whose delivery and whose return outlet are applied to the container of the carbonator in two substantially distanced, in order to cause a certain internal agitation of the water, which in any case to some extend makes more homogeneous the cooling generated by the evaporator inside the carbonator, but certainly not with the greatest possible effectiveness.
  • An alternative agitator usable in particular for carbonator of small size and reduced capacity, is the one constituted by an insulated electrical pump, immersed directly inside the carbonator, in the water fed therein, but said pump, still being electrically driven, will never be able to provide the absolute certainty that short circuits will not occur. Moreover, in case of failure of the electrical motor, considerable manpower needs to be expended to return the installation to its operating condition. Lastly, the entire pump must necessary be constructed of food-compatible material, since it operates directly inside a drink.
  • the object of the present invention is to overcome the above drawbacks.
  • the subject carbonator allows to obtain in its interior an effective rotor agitator, but without any of the related disadvantages, in fact with far greater effectiveness than in known solutions, also for high capacity carbonators. Moreover, the subject carbonator has a flow control unit integrated in the container of the carbonator, thus reducing related costs and sizes.
  • the reference number (1) designates the subject carbonator, of the type provided with a sealed container (29 comprising:
  • the agitator of the illustrated example is constituted by at least a rotor (4), constructed with food compatible material and freely rotating in correspondence with its fixed mechanical supports (42) internal to the container (2) and positioned in correspondence with the rotor (4) itself, which can be a propeller, a multi-blade rotating organ or any shaped rotating organ.
  • Said mechanical means (42) are in this case simply constituted substantially by a fixed shaft (43) internal to the container (2) and to the rotor itself, which rotates freely about it.
  • the rotor (4) is then combined with magnetic material (41) and subjected to actuator means (5) outside the container (2), able to create, when activated, a continuously rotating magnetic field in order remotely to control a continuous rotation of the rotor (4) itself.
  • the rotor (4) is shaped in such a way as to create a turbulence that allows an effective heat exchange between the carbonated water, refrigerated by the evaporator (7) and the coil (8). It therefore allows a perfect heat exchange able to allow a homogeneous cooling both of the aforesaid carbonated drink, and of the other alternative drink or drinks.
  • the rotor (4) positioned centrally in the bottom of the container (2) is a single one and it rotates about a vertical axis (44).
  • the aforesaid fixed shaft (43) has, on its summit, an abutment (45), for the axial locking of the rotor (4), which still remains free to rotate about said shaft (43).
  • the abutment (45) is shaped according to a surface that is able to serve as a flow deflector (in the illustrated case similarly to a washer), in such a way as to force the turbulent flow created by the rotor (4) to be addressed, at least for the most part, laterally to the rotor, instead of axially thereto.
  • the actuator means (5) are constituted, in the illustrated example, by magnetic means (51) outside the container (2).
  • the magnetic material (41) of the rotor (4) can be at least a magnet (which can be permanent) and also the magnetic means (51) comprise at least a magnet, in this first permanent example and for instance structured as an annulus and keyed on the shaft (66) of the motor (6) set in external rotation by an electrical motor (6).
  • the magnetic material (41) is also preferably constituted by a permanent magnet, but it may also be constituted, simply, by metallic material such as soft iron, which would still be driven in rotation by the external rotating permanent magnet of the magnetic means (51), though not synchronously.
  • the external magnetic means (51) are constituted not by a permanent magnet, but by electrical means, which may comprise at least an electromagnet, set in external rotation by the same electrical motor (6) mentioned above.
  • the same motor (6) advantageously sets in rotation a fan (10) for cooling a condenser (71) of a cooling system (72) whereof said evaporator (7) is a part.
  • the flow of carbonated water out of the carbonator (1) is in this case regulated and controlled by a flow control unit (35) for the carbonated water, advantageously integrated directly on the container (2), in correspondence with said outlet (33).
  • the flow control unit (35) is pivotally engaged, preferably, in a head (3) for closing the container, where are preferably also integrated at least the first inlet (31) for supplying the water to be carbonated, the second inlet (32) for supplying pressurised CO 2 gas to be added to the water, the outlet (33) of the carbonated water and the valve (34) as Figure 1 clearly shows.
  • the flow control unit (35) can be axially adjusted directly acting, from the exterior, on its summit and specifically on at least a corresponding summit notch (36), obtained on its head.
  • the flow control unit (35) in particular and in the illustrated example, comprises, below its head, a first threaded cylindrical body (37), followed by a second cylindrical body (38) with smaller diameter, which bears a gasket (39) and followed in turn by a cone frustum shaped end (40), as Figure 5 clearly shows, which is the end that regulates the flow, according to its greater or lesser insertion.
  • the seat (41) is complementary to said cylindrical bodies (37, 38) of the flow control unit (35): it is superiorly threaded and it engages the flow control unit (35) axially adjustable there, whilst the seal is assured by the aforesaid gasket (39), which abuts along a cylindrical wall (42) obtained at least in the terminal, cylindrical, part of the seat (41).
  • the seat (41) may also have a first cylindrical part, all threaded and with complementary diameter to the first threaded cylinder (37), for the regulating travel of the flow control unit (35), all obtained on the body (30) and a second cylindrical part (42), complementary to the second cylindrical body (38) of the flow control unit (35), totally obtained on the underlying head (3).
  • a particular agitator constituted by at least a rotor (4) which, being remotely actuated, by a rotating magnetic field and rotating freely about its own axis, for instance by means of said fixed shaft (43), providing simple support and not driving or rotating, eliminates at the root any problem with tightness against pressure, pollution of the carbonated water and, at the same time, with possible short circuits.
  • the rotor is also simple, rugged and compact, thus not requiring any maintenance and with minimal use of food compatible material, whereof it is nonetheless constituted.
  • the agitator could also be constituted by multiple rotors (for instance with vertical axis and positioned about the vertical axis of the container (2), or by two or more rotors with axis inclined outwards, to force the turbulent flow created by the rotors to be addressed at least to a great extent, laterally to the rotor, instead of axially), it is preferably constituted by a single rotor (4). It is advantageously provided, for the above purpose, with the aforesaid flow deflector.
  • a single motor is provided (6) both to cause the rotation of the magnetic means (51) external to the container (2), and to cause the rotation of the aforesaid fan (10) for cooling the underlying condenser (71).
