BEST MODE

(8) With particular reference to such figures, the apparatus for preparing and dispensing refrigerated products, such as for example water ice, creamy ice-creams, sorbets and the like, according to the invention is indicated in its entirety with 1.

(9) The apparatus 1 comprises at least one tank 2 for containing the product to be dispensed, made preferably of plastic transparent material. In the illustrated case, the apparatus provides two tanks 2 for containing the product, arranged side by side to prepare and dispense different products, but it is obviously possible to provide a different number of these tanks 2, in particular one single tank. The tanks 2 are open at their top and provided with a relative lid 20.

(10) The two tanks are mounted on a single base body 10. The base body 10 has a substantially prismatic shape and is predisposed to contain inside the operative members of the apparatus, known per se. The base body has a first base body side portion 22, a second base body side portion 24, an upper base body portion 26 and a lower base body portion 28. In particular inside the base body 10 a refrigeration system 11 is housed which comprises, in substantially known manner, a compressor and a condenser.

(11) Inside each containment tank 2 a mixing device 3 is arranged, comprising a screw member driven in rotation according to an axis longitudinal to the tank 2 to determine the continuous circulation of the product inside the same tank 2. The blades of the screw member 3 are predisposed to keep mixed the product and to convey it towards the front zone of the tank 2, where the dispensing zone is arranged.

(12) Inside the tank 2 a cooling device 4 is arranged for cooling the product until the suitable temperature. The cooling device 4 is preferably made up of a coil evaporator 14 arranged inside a tubular body 15, substantially cylindrical. The cylindrical body 15 is mounted with horizontal axis, according to the above mentioned rotation axis of the screw member.

(13) The containment tank 2 frontally has a dispensing device 5 connected with the lower portion of the same tank 2. The dispensing device 5 is provided with an obturator member 6 that can be operated by an outer lever member 7. The obturator member 6 is sliding inside a cylindrical seat constituted, with substantially vertical axis, by a sleeve 8 shaped by the tank 2. More precisely the obturator 6 is mobile, in known manner, by abutting elastic means, between a closure position and an open position of the opening of the sleeve 8.

(14) Inside the containment tank 2 a heat sensor is further arranged, being predisposed to control the temperature of the product at the dispensing zone. The heat sensor is preferably protruding at the front of the cylindrical body 15 of the cooling device 4, close to the front wall of the tank 2.

(15) The screw member of the mixing device 3 extends on the external surface of the cylindrical body 15 and is driven in rotation by a shaft 16 that axially crosses the same cylindrical body 15. The shaft 16 is predisposed to be operated by a motor member, preferably an electric motor, through a suitable reduction member.

(16) The base body 10 is closed at the front by a panel 12 of polycarbonate, transparent or opaque. The panel 12 is backlit by means of suitable lighting members 13, preferably of the LED type. As it is shown in FIGS. 1 and 2, the LEDs 13 are suitably arranged aligned vertically on opposite sides of the panel 12.

(17) The functioning of the apparatus is easy to understand from the preceding description.

(18) After the introduction of the product in the tank 2, through the upper opening, the preparation cycle is started, that is, the product is progressively refrigerated, passing from the liquid state to the frozen state for example of the water ice. In particular, the cooling device 4 is operated and the screw member of the mixing device 3 is driven in rotation at a predetermined speed.

(19) When required, the product is dispensed, by operating in opening the dispensing device 5 through the lever member 7.

(20) In use, the front panel 12 of the base body 10 is backlit through the LED lights 13. In this way, at the front part of the apparatus, a wide lighted surface is created. This wide surface enables the user to apply images to his choice and the like. The backlit of the same surface allows to give particular significance and vividness to the applied image.

(21) In FIGS. 3 and 4 a different embodiment of the apparatus is shown in which in front of the panel 12, inside the base body 10, a deflector member 17 is arranged predisposed to spread the light emitted by the LED lighting members 13. In particular the deflector 17 is constituted by a plate suitably shaped and of a material predisposed to reflect the lighting beams emitted by the LED 13. In the illustrated case, this plate shapes a central portion 17a and side portions 17b vertically extended in assembly position; the side portions 17b are symmetrically angled with respect to the central portion 17a, so as to make the plate take a concave configuration. Obviously, it is possible to provide that the deflector 17 has a shape different from the one illustrated, in particular that the concave zone of the plate is defined by a curved surface, for example a cylindrical zone.

(22) In the illustrated case, the LED lights 13 are mounted on a support 18 that extends vertically in front of the deflector 17, in a position median with respect to the base body 10. In particular, the support 18 is usefully constituted by a profile longitudinally shaping a central portion and a couple of lateral portions symmetrically angled according to the profile defined by the opposed portions 17a, 17b of the deflector 17. Practically, the LED lights 13 mounted on the different portions of the support 18 direct the light beams towards the respective opposite portions 17a, 17b of the deflector 17. Such opposite portions 17a, 17b reflect the light on the front panel 12 of the base body 10.

(23) In substance, the deflector 17 has the function of diffusing the light emitted by the LEDs 13 so as to obtain a uniform lighting on the whole front panel 12.

(24) In FIGS. 5 and 6 a further embodiment of the deflector 17 is illustrated that provides the use of a plate having a flat surface turned towards the front panel 12. In substance this plate is arranged on a plane parallel to the front panel 12 inside the base body 10. The LED lights 13 are mounted along the upper side and along the lower side of the flat plate 17 on respective supports 19 transversely protruding from the same plate. In particular, the supports 19 are constituted by fillets that substantially extend for the whole length of the above mentioned upper and lower sides of the plate 17. The LED lights 13 are arranged in series, regularly spaced, along the fillets.

(25) The apparatus according to the invention therefore attains the scope of offering to the user a high level of customization.

(26) A feature of the invention is that the panel of polycarbonate presents lightness, brightness and high resistance to operating temperatures of the apparatus. The panel is also easy to clean, so as to preserve its visual qualities over time.

(27) Another advantageous aspect of the invention is given by the fact that the LED backlit panel it is easily mountable also on existing machines and it can thus enable to give such existing machines an innovative aspect.

(28) The equipment described by way of example is susceptible of numerous modifications and variations according to the different needs. In the preceding description reference has been made to an apparatus for preparing and dispensing of refrigerated products; it is however evident that the backlit panel according to the invention can be advantageously applied also to equipment for preparing and dispensing hot beverages and the like.

(29) In practice, the embodiment of the invention, the materials used, as well as the shape and dimensions, may vary depending on the requirements.

(30) Should the technical characteristics mentioned in each claim be followed by reference signs, such reference signs were included strictly with the aim of enhancing the understanding the claims and hence they shall not be deemed restrictive in any manner whatsoever on the scope of each element identified for exemplifying purposes by such reference signs.
