DETAILED DESCRIPTION

[0024] Suitably, hereinafter, the term “refrigerated counter” refers to average-temperature counters, i.e., counters adapted to ensure conservation temperatures of products close to zero. In particular, with reference to standard UNI EN 23953, the counters to which the present innovation refer belong to climate class MO with temperatures comprised between −1° C. and +4° C., to class M1 with temperatures between −1° C. and +5° C., or to class M2 with temperatures between −1° C. and 7° C.

[0025] In particular, the refrigerated display counter 1 according to the present innovation is of the type provided for the display of food products, and can be used for assisted or free sales.

[0026] In particular, the refrigerated display counter 1 according to the present innovation is of the autonomous type (also called “plug-in”), as all the components of the refrigerant circuit are entirely housed therein and, therefore, exclusively requires the power supply connection to the electrical grid.

[0027] As depicted in FIG. 1, the refrigerated display counter 1 comprises a display structure 2 for containing food products to be displayed and refrigerated. Preferably, the display structure 2 has a tub shape inside which a compartment is defined for positioning and containing the food products to be displayed and refrigerated.

[0028] Suitably, the refrigerated display counter 1 according to the present invention comprises a traditional compression refrigerant circuit 6 of a refrigerant fluid. Suitably, the refrigerant circuit 6 for cooling the display structure 2 is positioned below the latter. In particular, the evaporator (not depicted) of the refrigerant circuit 6 is positioned immediately below the display structure 2 and inside the bottom portion 3 of the display structure 2. The refrigerant circuit 6 comprises a condenser 11 and a compressor 12 housed inside a containment structure 5.

[0029] Suitably, the counter 1 comprises a command and control unit (e.g., a processor) connected to the components of the refrigerant circuit for its management and control.

[0030] Suitably, the containment structure 5 is substantially box-shaped and delimits an inner chamber 17 in which the condenser 11, the compressor 12 and, preferably, a condensate collection tank (not depicted) are housed.

[0031] In particular, the containment structure 5 is defined by several (preferably four) side walls 21, 22, 23, 24 arranged vertically. Suitably, the containment structure 5 is configured so that its side walls 21, 22, 23, 24 are associated with each other by removable mechanical fixing means, so as to allow easy and quick access to the inner chamber 17 of the containment structure 5. The side walls 21, 22, 23, 24 comprise a first side wall 21 and a second side wall 22 opposite the first side wall 21. The condenser 11 is housed within the containment structure 5 at or near the first side wall 21. The compressor 12 is housed within the containment structure 5 at or near the second side wall 22. Advantageously, the first side wall 21 and the second side wall 22 comprise respective perforated grilles 36, 46. Suitably, an air flow enters inside the containment structure 5 from the perforated grille 36 of the first side wall 21 to substantially horizontally cross the inner chamber 17. The air flow exits the containment structure 5 from the perforated grille 37 of the second side wall 22 and/or from an open bottom of the containment structure 5. Suitably, the condenser 11 is associated with a fan 41 which sucks the entering air flow so that it crosses the condenser 11 and so that it circulates inside the inner chamber 17 and thus cools the compressor 12, thereby reducing the risk of its overheating. Preferably, the fan 41 is associated with the condenser 11 at the innermost face of the latter, i.e., the face facing the inner chamber 17.

[0032] The condenser 11 comprises a plurality of metal slats defining the main heat exchange surface and which are arranged substantially vertically so as to be superficially lapped by the air flow which, crossing the condenser 11, sliding substantially parallel with respect to said slats. The front edge of the slats closest to the first side wall 21 defines a surface to be cleaned 16 of the condenser 11.

[0033] According to the present innovation, to clean the surface to be cleaned 16, the refrigerated display counter 1 comprises a cleaning device 10.

[0034] The cleaning device 10 comprises a cleaning element 31 movable along the surface to be cleaned 16, a handle 32 graspable by an operator for moving the cleaning element 31 and a connecting support 33 for connecting the cleaning element 31 and the handle 32 together. The cleaning element 31 is shaped like a brush or similar device adapted to clean a surface. The connecting support 33 is through a hole 35 provided in the first side wall 21, which is interposed between the cleaning element 31 and the handle 32. The hole 35 as shown in the appended drawings is shaped like an elongated slot according to a sliding direction of said cleaning device 10. The slotted hole 35 is straight and vertically oriented. According to the present innovation, an operator can use the cleaning device 10 by grasping the handle 32 and sliding the cleaning device 10 along the slotted hole 35 without the need to remove the first side wall 21. By operating the handle 32, the operator slides the cleaning element 31 along the surface to be cleaned 16, thereby promoting the removal of dust and/or other dirt from the surface to be cleaned 16. According to other embodiments (not depicted), the hole 35 could be shaped differently from a straight slot. For example, the hole 35 could be curved or circular to allow a rotation or rototranslation of the cleaning element 31 on the surface to be cleaned 16.

[0035] The cleaning device 10 further comprises a sliding guide 37 for guiding the connecting support 33 and the cleaning element 31 therewith, along the surface to be cleaned 16. The sliding guide 37 is fixed to a frame 42 provided in the containment structure 5 so as to also be covered by the first side wall 21. The sliding guide 37 is fixed to one or more supports 39 provided in the frame 42, for example by means of screws or other similar connection. The frame 42 is shaped like a quadrangular frame with a central hole to allow air to pass towards the condenser 11. The cleaning device 10 further comprises at least one sliding bearing 38 (two sliding bearings 38 in the embodiment of the appended drawings) sliding along the sliding guide 37. The sliding bearings 38 are fixed to the connecting support 33, so as to allow the integral sliding of the connecting support 33 and the sliding bearings 38 along the sliding guide 37.

[0036] According to other embodiments (not shown) of the present invention, the refrigerated display counter 1 could also comprise at least a second cleaning device 10 associated with one or more of the other side walls 22, 23, 23 of the containment structure 5. For example, a second cleaning device 10 could be associated with the second side wall 22 for cleaning a surface to be cleaned placed on the compressor 12.

[0037] It is clear from the above that the refrigerated display counter according to the innovation is particularly advantageous, as the cleaning device of the present innovation can be operated externally by an operator without removing any structure of the refrigerated display counter. This allows to prevent malfunctions due to the accumulation of dirt without the intervention of specialised staff. Intervening manually on a handle accessible from the outside, even the unspecialised operator can clean the condenser easily and safely, without using tools and without removing the cover panel which also has the function of protecting from direct access to live parts or sharp parts such as the fins of the exchanger.

[0038] Furthermore, the system is inexpensive enough to be applied to any refrigerated display counter, even already existing.

[0039] The present utility model has been illustrated and described in a preferred embodiment thereof, but it is understood that executive variants can be made thereto in practice, without however departing from the scope of protection of the present utility model patent.
