Definitions

  • the present invention regards a display cabinet for refrigerated products according to the preamble of the independent claim 1.
  • the display cabinets of known type can be of vertical type, e.g. with column or walls, or horizontal, of the type with counter, with tank or with well.
  • the display cabinets of known type usually comprise a metallic support structure and an insulating structure, made of thermal insulation material, fixed to the support structure and adapted to define therewith a containment volume for the foods to be preserved. More in detail, with particular reference to the vertical display cabinets, the support structure is of cabin type and internally delimits a cooled chamber, accessible to users in order to allow the latter to take the product displayed within the display cabinet.
  • the support structure of the display cabinets of known type comprises a base wall, susceptible of being placed substantially in abutment against the ground, an opposite top wall, known in the technical jargon of the field with the term "top”, two lateral shoulders, termed “flanks”, and a rear wall, termed “back”, opposite with respect to the access opening for the cooled chamber.
  • the back of the display cabinets of known type is usually blind and is susceptible of being placed in abutment against a perimeter wall of the business location where the display cabinet is placed (hence the term "wall" indicates the type of display cabinet).
  • the display cabinets of known type also comprise a thermal cooling unit, which comprises an evaporator, usually placed below the cooled chamber and hydraulically connected to a cooling station placed outside the sales location, and ventilation means, in order to force the convection of air and allow the recirculation within the cooled chamber.
  • the aforesaid recirculation of the air is attained by forcing the air, through the aforesaid ventilation means, to traverse the cooled chamber in order to induce a closed circuit movement of the air within the same cooled chamber, in order to allow cooling the interior of the chamber.
  • the recirculation circuit provides for a first passage opening, through which the refrigerated air enters within the cooled chamber.
  • first passage opening is usually placed below the cooled chamber (usually being placed below the ventilation means).
  • a first drawback lies in the fact that they do not allow preserving foodstuffs which require different preservation temperatures within the same display cabinet.
  • a further drawback lies in the fact that such wall display cabinets, in the event in which they are employed for forming aisles that are not supported by a wall, are usually placed in pairs with the respective backs facing.
  • column display cabinets e.g. like that described in the document US 3769805 , which is provided with a central column, to which the display shelves are fixed, and such central column has a plurality of recovery holes in order to allow the recirculation of the air between the refrigeration chamber and a technical compartment within which the cooling means are placed.
  • display cabinets for refrigerated products have been developed, for example of the type described in the patent US 3392543 or in the document US2001/0047660 , which are provided with a central dividing wall that divides the cooled chamber into a first half-chamber, accessible from a first door, and a second half-chamber, accessible from a second door. Also fixed on the central dividing wall are two series of display shelves, one for each half-chamber. For such reason, the latter display cabinets take the name "bifacial" in the technical jargon.
  • the support structure also comprises a technical compartment, placed above the cooled chamber and within which two separate cooling units are placed. More particularly, a first cooling unit is placed above the first half-chamber, and a second cooling unit is placed above the second half-chamber.
  • the aforesaid display cabinet provides that the two half-chambers be air-isolated from the central wall and in particular provides for two recirculation circuits, each of which intercepted by a corresponding cooling unit intended to cool the air flow passing into such recirculation circuit.
  • the corresponding recirculation circuit provides for a first delivery section, parallel to the first (or second) door and along which the air exiting from the cooling unit flows, and a recovery section, passing into the central wall, which at its interior defines a return channel.
  • Each circuit also provides for a connection section passing through a lower technical compartment, placed under the cooled chamber. Therefore, the two recirculation circuits are at most joined with the aforesaid recovery section passing within the central wall.
  • the air is forced into the recovery section by ventilation means placed in the return channel, i.e. within the central wall, at the lower technical compartment.
  • the air that flows along the first (single) delivery section follows a substantially sinusoidal path within spaces defined by the display shelves, in order to reach the various displayed products to be refrigerated.
  • a further drawback lies in the fact that such solution has proven to be economically expensive, also regarding assembly, comprising two separate cooling units and providing for the placement of the ventilation means within the central wall. In addition, such placement makes it difficult to access the same ventilation means in order to carry out the necessary maintenance thereof.
  • Refrigerator cells of walk-in type are also known, for example described in the document DE 202017103728 , which are provided with two series of display shelves that between them delimit a work zone adapted to allow an operator to enter within the cell in order to load the food products to be stored.
  • Such refrigerator cells comprise an air recirculation system with channels, which is provided with two recirculation circuits, each of which provided with a recovery mouth, placed at an evaporator, and with respective recirculation ducts, provided with a plurality of outlet openings, made in proximity to the sides on which the display shelves are placed.
  • a further object of the present finding is to provide a display cabinet which has a high thermal efficiency.
  • a further object of the present finding is to provide a display cabinet whose maintenance is simple to carry out.
  • a further object of the present finding is to provide a display cabinet which requires reduced energy consumption.
  • reference number 1 indicates the display cabinet for refrigerated products, object of the present invention.
  • the present display cabinet 1 can be of the type employable for preserving foodstuffs at temperatures higher than that of freezing of the foodstuffs, and at temperatures lower than the freezing temperatures.
  • the display cabinet can also be of another type such as for example of vertical type with column, of semi-vertical type, or horizontal type with counter, with tank or with well.
  • the display cabinet 1 for refrigerated products comprises a support structure 2, preferably made of metal material.
  • the support structure 2 has substantially box-like form and is extended between a base wall, susceptible of being placed in abutment against the ground, and an opposite top wall.
  • the aforesaid access openings A, B are closeable, e.g. by doors, which can be of swinging type, i.e. hinged to the support structure, as illustrated in the enclosed figure 1 , or of slidable type, in order to insulate refrigeration chamber 20 from the outside environment and maintain a substantially constant temperature within the refrigeration chamber 20.
  • the display cabinet 1 comprises a first delivery mouth 211' placed at the first access side 21' and a second delivery mouth 211", placed at the second access side 21".

More in detail, the ventilation means 4 are placed at the recovery mouth 212, within the first technical compartment 22, and the cooling means 5 are placed above the ventilation means 4, along the vertical extension direction Y.
  • the air passes through the outlet mouth 212 suctioned by the ventilation means 4 and, once it has gone beyond the ventilation means 4, it reaches the cooling means 5 placed above, in order to then be divided into two sections (right and left) towards the delivery mouths 211.
  • the two right and left sections are in particular descending sections, in which the air flows from the cooling means 5 that are placed raised (being placed above the ventilation means 4) towards the delivery mouths 211 that are instead placed placed placed at the first separation wall 200 of the first technical compartment 22.
