Definitions

  • the present invention regards a display cabinet for preserving food products and a process for mounting said display cabinet, according to the preamble of the respective independent claims.
  • the present display cabinet is advantageously intended to be employed in stores, supermarkets or other business premises for the display and sales of perishable food goods and otherwise.
  • the display cabinet, object of the present invention is advantageously intended to be cooled in order to be used for containing products which require a controlled temperature.
  • the present display cabinet and the relative mounting process are therefore inserted in the industrial field of production of display cabinets, e.g. refrigerators, foodstuffs, in particular in the field of production of counters and display cabinets for small, medium and large scale mass distribution.
  • display cabinets e.g. refrigerators, foodstuffs
  • the display cabinets also known in the technical jargon with the expression refrigerated display cabinets or refrigerated counters, are used for the display of foodstuffs at a controlled temperature, so as to maintain unchanged over time the characteristics of the displayed food product.
  • refrigerated display cabinets or refrigerated counters are used for the display of foodstuffs at a controlled temperature, so as to maintain unchanged over time the characteristics of the displayed food product.
  • various display cabinets which are distinguished by shape and by mode of display of the produces to be preserved.
  • 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 frame and an insulating structure, made of thermal insulation material, fixed to the support frame and adapted to define, with the latter, a containment volume for the foods to be preserved.
  • the insulating structure comprises at least one base portion, placed parallel to the ground and which defines a support surface for an evaporator adapted to cool the aforesaid containment volume, as better described below, and at least one back portion, vertically extended with respect to the base portion and defining a rear wall of the display cabinet.
  • the base portion of the insulating structure is provided with at least one drain trap, placed in a usually central position of the base portion in order to allow the discharge of the condensate water created within the cooled chamber of the display cabinet and in particular present on the base portion of the insulating structure.
  • the base portion of the insulating structure comprises at least one base wall, tilted with respect to a horizontal plane so as to define a tilted surface along which the condensate water can flow in order to be channeled to the drain trap.
  • the display cabinets are associated with a cooling unit, which as described above comprises at least one evaporator, placed within the display cabinet, a condenser, usually placed at a distance from the display cabinet, and at least one compressor, usually placed outside the building in which the display cabinet is placed.
  • a cooling unit which as described above comprises at least one evaporator, placed within the display cabinet, a condenser, usually placed at a distance from the display cabinet, and at least one compressor, usually placed outside the building in which the display cabinet is placed.
  • the insulating structure of the display cabinets of known type is attained in an integral body, i.e. it comprises a single insulating panel, of sandwich type, which is composed, in a per se known manner, by two external containment plates, made of metallic material, e.g. galvanized steel, and by an internal insulating element, interposed between the two containment plates, which is usually attained by means of foaming of a polymer with reduced thermal conductivity, e.g. polyurethane or polystyrene.
  • a polymer with reduced thermal conductivity e.g. polyurethane or polystyrene.
  • the insulating structure in an integral body in particular made with a single shaped insulating panel, defines the external shape of the same display cabinet and hence the base portion and the back portion are made in a single body/integral with each other.
  • the insulating structure with integral body of the display cabinets of known type is usually attained through a step of forming the two facing containment plates of the sandwich panel in order to form the external shape of the display cabinet that one wishes to make, and a step of foaming the insulating polymer between the two containment plates, e.g. by means of use of low-density polyurethane.
  • the step of forming the two plates of the sandwich panel can be attained by means of bending a single sheet or by means of fixing multiple separate sheets, e.g. through a process of welding, gluing or mechanical fixing, in order to obtain the final shape of the insulating structure.
  • the display cabinets of known type have in practice shown that they do not lack drawbacks.
  • a first drawback of such display cabinets of known type lies in the fact that the production of the insulating structure and the assembly of the display cabinet are particularly complicated, in particular in the case of display cabinets that provide for a rather complex shape, for example since it is defined by a plurality of curves or geometrically complex figures.
  • Such difficulty lies in the fact that the step of forming the two containment plates requires a plurality of complex and difficult operations of bending and/or mechanical fixing of multiple metallic plates.
  • a further drawback of the display cabinets of known type lies in the fact that the step of foaming of the chamber defined by the two shaped containment plates - in particular in the case of large-size display cabinets - results complicated to obtain through a single injection operation, since it must provide for multiple separate injections in order to reach the entire volume of the chamber subtended by the two containment plates.
  • a further drawback of the display cabinets of known type lies in the fact that the attainment of an insulating structure made of an integral body constituted by a single insulating panel does not allow varying the production in a flexible manner, with similar models that are different from each other (even only a little bit), for example by display size and spaces.
  • the tilt of the base portion of the insulating structure with respect to the back portion of the latter depends on the depth of the display cabinet itself, and in particular increases with the increase of the latter. Indeed, in order to allow the correct draining of the condensate water towards the drain trap it is necessary to ensure a sufficient tilt adapted to allow an effective and quick downflow of the water.
  • WO 2014/189645 A1 describes a modular refrigerator of known type in which the adjacent walls can be connected by means of hinges. Nevertheless, in such solution of known type, the adjacent walls can be mounted in perpendicular position with respect to each other so as to allow the correct insulation of the internal space of the refrigerator.
  • the problem underlying the present invention is therefore that of overcoming the drawbacks shown by the above-described solutions of known type, by providing a display cabinet, which can be made in a versatile manner according to the client's shape and size requirements.
  • a further object of the present invention is that of providing a display cabinet and a method of assembly thereof which is simple and inexpensive to attain.
  • a further object of the present invention is that of providing a display cabinet and a method of assembly thereof that is entirely reliable in operation.
  • a further object of the present invention is that of providing a display cabinet and a method of assembly thereof that require the use of a limited number of components employable for different models.
  • reference number 1 overall indicates the display cabinet, object of the present invention.
  • the display cabinet 1 according to the present invention is advantageously intended to be cooled in order to be employed for preserving different foodstuffs at a controlled temperature, and simultaneously allow a display thereof, e.g. for sales purposes.
  • the present display cabinet 1 can be of the type employable for preserving foodstuffs at temperatures higher than that of freezing of the same foodstuffs, or at temperatures lower than the aforesaid freezing temperature.
  • the display cabinet can also be of another type such as for example of semi-vertical type, horizontal type with counter, with tank or with well.
