Definitions

  • the present invention relates to a refrigeration device particularly suitable for vending machines according to the preamble of claim 1.
  • a refrigeration device particularly suitable for vending machines according to the preamble of claim 1.
  • Such a device is known, e.g., by US 6 550 270 B2 .
  • Vending machines which have, at a lower portion of the containment frame, a region for housing a refrigeration device that is adapted to circulate refrigerated air inside the containment frame, so as to allow the products to be dispensed, contained inside the refrigeration chamber formed inside said frame (and usually above the housing region), to be preserved at the optimum temperature.
  • These refrigeration devices generally comprise refrigeration means, which are constituted by ventilation means, associated with a refrigeration element crossed by a liquid refrigerant, and by a control unit.
  • control unit In currently commercially available vending machines, the control unit is often interposed between the refrigeration means and the front panel for accessing the containment frame (and the housing region) and this inevitably causes difficulties for extracting the refrigeration means, which are usually mounted on substantially horizontal sliders.
  • a gasket is provided, which is designed to be interposed, when the refrigeration means are accommodated at its housing region, between said device and the lower panel of the refrigeration chamber.
  • the guides that form the sliders are slightly inclined: in this manner, by pushing the refrigeration device toward the housing region, the device moves slightly upwardly, so as to allow, during insertion, a compression of the gasket against the downward-facing surface of the lower panel.
  • the aim of the present invention is to eliminate or at least reduce drastically the drawbacks noted above in known types of refrigeration devices particularly for vending machines.
  • an object of the present invention is to provide a refrigeration device that can be extracted and inserted practically and effectively within the respective housing region, allowing direct access from the front panel without having to move the vending machine.
  • Another object of the invention is to provide a refrigeration device that can offer better reliability and tightness with respect to currently commercially available devices.
  • Another object of the invention is to provide a refrigeration device that allows to inspect rapidly and practically the control unit as well.
  • Another object of the present invention is to provide a refrigeration device that has a very simple structure, is highly durable, easy to use and competitive in terms of production cost, so that its application is advantageous also from an economical standpoint.
  • a refrigeration device is advantageously associable with a vending machine 10.
  • the refrigeration device 1 is provided with refrigeration means 2, which are generally constituted by a refrigeration element 2a and by ventilation means 3, which are designed to force the air through the refrigeration element 2a and then convey it, through a delivery duct not shown in the figures, into a refrigeration chamber 11 formed inside the vending machine 10.
  • refrigeration means 2 which are generally constituted by a refrigeration element 2a and by ventilation means 3, which are designed to force the air through the refrigeration element 2a and then convey it, through a delivery duct not shown in the figures, into a refrigeration chamber 11 formed inside the vending machine 10.
  • the refrigeration means 2 are adapted to move between an active position (shown in the figures), in which they are accommodated within a housing 5, and an extraction position, in which they are at least partially arranged outside said housing 5.
  • the housing 5 is formed at a lower portion of containment frame 12 of the vending machine 10.
  • said housing 5 is formed laterally by side walls 5 a of the containment frame 12, downwardly by a lower end face 5b of the containment frame 12, and upwardly by a lower surface 6, which is supported by the containment frame 12 and generally also forms the footing of the refrigeration chamber 11.
  • the vending machine 10 is provided with a front closure panel, which is pivoted to one of the side walls 5a so as to allow the user to access the refrigeration chamber 11 and the housing 5.
  • the refrigeration device 1 is provided with at least one sealing gasket 7, which is arranged between the lower surface 6 and an upper edge 8 of the refrigeration means when the refrigeration means 2 are in the active position.
  • the refrigeration device 1 is provided with means for moving the upper edge 8 of the refrigeration means 2 with respect to the lower surface 6, which as a consequence of the intervention of the user, in this case of the person in charge of maintaining the vending machine 10, move the upper edge 8 with respect to the lower surface 6 substantially at right angles to the plane of arrangement of the sealing gasket 7.
  • the lower surface 6 and the upper edge 8 lie on a plane that is substantially horizontal during use and accordingly the sealing gasket 7, which is interposed between them, likewise lies on a horizontal plane.
  • said lifting means 9 are adapted to move the upper edge 8 of the refrigeration means toward the lower surface 6 or away from it, so as to at least partially compress the sealing gasket 7 interposed between them, by moving along a substantially vertical direction.
  • first supporting device 15 for the refrigeration means 2 which is slidingly supported by the containment frame 12 in order to move between an active position, in which it is accommodated within the housing 5 formed by the containment frame 12, and an extraction position, in which it is arranged at least partially outside said housing 5.
  • the lifting means can be associated with at least one actuation lever system 13, which can be rotatably supported by the first device 15 for supporting the refrigeration means 2.
  • the sealing gasket 7 lies at a peripheral portion of the upper edge 8 of the refrigeration means 2.
  • the side walls 5a (or, in a fully equivalent manner, the lower end face 5b) of the containment frame 12 may support two guides, which can be slidingly engaged by a slider, which constitutes the first supporting device 15, so as to allow the refrigeration means 2 to move between the active position and the extraction position.
  • the first supporting device 15 can be provided with a pulling handle 16, so as to facilitate insertion (and extraction) of the refrigeration means 2 with respect to the respective housing 5 by the maintenance technician.
  • the first supporting device 15 may also support a condenser 17, which is usually associated with the refrigeration means 2 in order to ensures its optimum operation.
  • the actuation lever systems 13 can be rotatably supported by the first supporting device 15 at respective pivoting portions 13a, while at an intermediate position said lever systems 13 are provided with a pin 30, which can engage a respective substantially vertical guide 31 supported by a respective L-shaped element 32, so that upon rotation (in one direction or the other) of the lever system 13 (about the pivoting portion 13a) the L-shaped element 32 slides (along a direction that is horizontal during use) with a back-and-forth motion.
  • the L-shaped element 32 is provided with an inclined guide 34, which is arranged at a portion thereof that is designed to face a shoulder 35 (rigidly coupled to the first supporting element 15), which supports a second vertical guide 36.
  • the inclined guides 34 and the corresponding second vertical guides 36 are slidingly engaged by an end pivot 37, which is supported by a transverse bar 38 on which the refrigeration means 2 rest so as to ensure, as a consequence of the back-and-forth horizontal motion of the L-shaped element 32, the lifting (or lowering) of the transverse bar 38 and therefore of the refrigeration means 2.
  • transverse bars 38 each of which has, at its free ends, an end pivot 37, which can slide within a respective inclined guide 34 (supported by the L-shaped element) and within a second vertical guide 36 (formed at a shoulder 35).
  • the inclined guides 34 may have, at their upper end, a flat portion that is designed to keep the transverse bars 38 in stable contact or bearing condition when they are in the raised position.
  • the refrigeration device 1 may comprise a second supporting device 20 for a control unit 21, said second supporting device 20 being slidingly supported by the containment frame 12, in order to move between a position for insertion within a respective further housing 22 and an inspection position, in which it is extracted at least partially from the respective housing 22.
  • the housing 22 is formed below the refrigeration means 2.
  • the present invention provides a refrigeration device 1 that has, at the same time, both the movement means associated with the sealing gasket and the second supporting device for the control unit, which is slidingly supported by the containment frame.
  • the refrigeration means 2 are to be extracted from the housing, after naturally opening the front panel, one acts on the actuation lever system or systems 13, so as to allow the lifting means to lower the refrigeration means (and therefore the sealing gasket 7 associated with them) with respect to to the lower surface 6, so as to provide a clearance between the sealing gasket 7 and the lower surface 6.
  • control unit 21 also is supported by the second supporting device 20, it is evident that it is possible to simply and effectively extract independently both the refrigeration means 2 (optionally associated with the relative movement means) and said control unit 21, since its housing 22 does not occupy a region subjected to the translational motion of the refrigeration means 2 by being formed below said refrigeration means 2.
  • the materials used may be any according to requirements.
