Description

  • The present invention relates to a machine for the production and distribution of ice.
  • Machines for ice production have existed on the market for some time, of the type comprising a tubular pipe for forming the ice, covered by a refrigerator group evaporator, and equipped with an auger at its interior that transfers the ice to the production outlet, to which a ring nut pierced with drawing holes is associated.
  • In particular, the machines referred to herein are conceived to produce ice in particles, so-called "nuggets" or "flakers" in granule or cube o cylindric form.
  • One of the main problems of these machines involves positioning the machine in an area that is easily accessible, making the ice readily available for the user, without the machine installation position being inconvenient.
  • Generally, this type of machine is equipped with an external ice dispenser on one of its sides, and the machine itself if set directly on the floor.
  • In this case, the user is forced to bend down to reach the ice that accumulates in a container substantially at ground level, where polluting and contaminating agents tend to concentrate, together with any dust in the atmosphere.
  • Moreover, ice dispensers of the prior art generally comprise a simple collection chamber wherein the produced ice particles are stored. In order to retrieve the ice particles, the user must use some form of shovel, thereby introducing pollutants. More importantly, in order for the ice particles to be accessed, the collection chamber must either be open to the atmosphere or have a door that enables it to be so. This further leaves the ice susceptible to pollutants.
  • Furthermore, such ice dispensers do not have good thermal insulation, which results in conglomeration of the ice particles.
  • For these reasons, the machines are often raised to a higher level above the ground for easier access and better hygiene, and the external ice dispenser is positioned on the side or the bottom of the machine.
  • In this case, the advantages of improved hygiene and easy access to the ice at standing height are compromised by the fact that the position of the machine often obstructs transit, and complicated systems must be created to support the machine, including suitable support brackets and safety locking systems which are not necessary when the machine is simply positioned on the ground. Furthermore, when the machine is placed in a raised position, not all parts are easily accessed by the user.
  • The invention of WO2007090523 discloses the use of a conveying member being an axial extension of the tubular pipe of the ice production unit, such that the ice outlet from the conveying member is at a level substantially higher than the top of the machine. However, although not at ground level, the delivery outlet having an open end is still susceptible to contamination by air pollutants and there is no disclosure of an ice dispenser having thermal insulation. Furthermore, this does not provide a readily available supply of ice particles desired. Moreover, the amount of ice dispensed depends solely on the amount of ice produced.
  • US7003974 and US3211338 disclose machines for the production and distribution of ice particles.
  • The technical task proposed by the present invention is therefore that of providing a machine for the production and distribution of ice particles that overcomes the noted technical drawbacks of the prior art.
  • Within the scope of this technical task, one object of the invention is that of providing a machine for the production and distribution of ice particles that protects the ice from pollutants or dust present in the environment where the machine is installed.
  • Another object of the invention is that of providing a machine for the production and distribution of ice particles that has a supply position with comfortable user access to the ice dispenser while making all machine parts easily accessible for inspection, maintenance, assembly, disassembly and cleaning, at the same time.
  • A further object of the invention is that of providing a machine for the production and distribution of ice particles that permits positioning the ice dispenser at standing height positioning the ice dispenser at standing height without complicating the machine structure or requiring a specific support structure in a position raised from the ground.
  • Another object of the invention is that of providing a machine for the production and distribution of ice particles that provides a readily available supply of ice particles.
  • A further object of the invention is that of providing a machine for the production and distribution of ice particles that dispenses a pre-set amount of ice upon demand.
  • Another object of the invention is that of providing a machine for the production and distribution of ice particles that avoids conglomeration of said ice particles.
  • A last but not least object of the invention is that of providing a machine for the production and distribution of ice particles that is simple and economical to construct.
  • The technical task, as well as these and other objects, are achieved according to the present invention by a machine for the production and distribution of ice particles, having a frame comprising a refrigerator group evaporator and forming means for forming said ice particles, said machine further having a distributing device for distributing said ice particles and comprising a closed housing for storing said ice particles, characterised in that said distributing device is located outside of said frame.
  • The closed housing protects the ice particles from pollutants and dust present in the environment where the machine is installed. Furthermore, the closed housing is thermally insulated and the distributing device helps to prevent conglomeration of the ice particles.
  • The distributing device being located outside of the frame permits positioning the ice dispenser at standing height without complicating the machine structure or requiring a specific support structure in a position raised from the ground.
  • Advantageously, the closed housing permits ice particles to be produced and stored until distribution is desired, thereby providing a readily available supply of ice particles. Furthermore, the dispensing not being dependent on the production of ice particles each time ice is demanded, it is possible to calibrate the machine to dispense a pre-set amount of ice each time the distributing device is activated.
  • Other characteristics of the present invention are moreover defined in the subsequent claims. Further characteristics and advantages of the present invention will be more evident from the description of a preferred, but not exclusive, embodiment of the machine for the production and distribution of ice particles according to the finding, illustrated in the attached non-limiting drawings, wherein:
    • Figure 1 shows a partially exposed cross sectional view of the machine in accordance with one embodiment of the invention.
    • Figure 2 shows an enlarged cross-sectional view of the distributing device of the invention in accordance with one embodiment of the invention.
  • With reference to the above figures, the machine comprises a frame (1) comprising a refrigerator group evaporator (2) and forming means (3) for forming ice particles. In the embodiment shown in figure 1, said forming means (3) are shown as being in the form of a tubular pipe with an auger inside the refrigerator group evaporator (2), which is capable of transferring the ice produced to an outlet to which a ring nut pierced with drawing holes is associated. A conveying member (4) attached thereto is then capable of transferring the ice particles thus produced via an annular channel (4A) into a closed housing (5) located outside of the frame (1) and towards a deflection member (6) designed to deflect the ice particles onto an inclined surface (7) within the housing.
  • However, it will be appreciated that other forms of refrigerator group evaporator and forming means for forming ice particles can be used with the machine of the present invention.
  • The housing (5) is preferably insulated and is designed to be able to store the ice particles. Dispensing means, preferably in the form of an agitator (8) can move the ice particles contained within the housing (5) towards a delivery outlet (9) from the housing. An optional funnel (10) connected to the delivery outlet can direct the ice particles towards a receiving container (11) such as a glass. The use of an agitator (8) attached to a motor (8A) helps to prevent conglomeration of the ice particles in the housing (5). Furthermore, the use of an agitator (8) and a delivery outlet (9) enables the machine to take advantage of gravity to move the ice particles from the housing (5) to the receiving container (11).
  • The housing (2) can optionally comprise a duct (12) for drainage of any melted ice. The floor (13) of the housing upon which the ice particles rest is preferably inclined such that the delivery outlet (9) is located higher in the housing than the duct (12), thereby preventing melted ice from exiting the delivery outlet.
  • The agitator (8) preferably has at least one blade (14), said blade having at least one aperture (15). This facilitates minimisation of torque, thereby saving energy. The blade may be of a shape conforming to the shape of the housing floor (13).
  • The machine can optionally comprise a second duct (16) for the additional drainage of melted ice, said duct being located below the delivery outlet (9) .
  • Importantly, the machine optionally comprises an electronic control unit for controlling the amount of ice produced or distributed. The control unit can be connected to the distributing means and/or to the refrigerator group evaporator and the forming means.
  • First detecting means, preferably in the form of at least one sensor (17), can be provided for detecting the presence of a receiving container (11) below the delivery outlet (9) from the housing (5). This is connected to the electronic control unit such that, when the signal from the first detecting means is correct, the dispensing means are activated. In this way, the ice particles are stored in the housing, protected from pollutants, until a receiving container is placed beneath the delivery outlet, at which point ice particles are dispensed thereinto. The machine is further optionally provided with electronic control means, connected to the control unit, for setting the duration of activation of the dispensing means. In this way, either the manufacturer or the user can pre-set the amount of ice to be dispensed each time the distributing device is activated.
  • Second detecting means, preferably in the form of at least one search light (18), can be provided for detecting the level of ice in the housing (5). This is connected to the electronic control unit such that, when the signal from the second detecting means is correct, the refrigerator group evaporator and the forming means are activated. In this way, the housing always contains a ready supply of ice particles such that the distribution thereof is not dependent on the particles first having to be produced.
  • The machine for production and distribution of ice particles thus conceived is susceptible to numerous modifications and variations, all falling within the scope of the inventive concept; furthermore, all details may be substituted by technically equivalent elements. In practice, any material type or size may be used, according to the needs and the state of the art.
