Definitions

  • the present invention relates to a refrigerated display case of the type comprising essentially a tank carried by a chassis containing a cold battery, a folding front window pivotally attached to the front of the tank and a single loading platform substantially covering the opening surface of tank.
  • refrigerated display cases are made from a tank fitted with one or more loading platforms fixed to a chassis and comprising uprights connected at their upper end by a cross member, said crosspieces allowing the fixing of a glass cover falling pivoting around a horizontal axis located substantially along the cross.
  • One of the disadvantages of the uprights and crosspieces in a refrigerated display case is that they obstruct the passage of a user's arms, especially on the rear side of the display case, to access the products on display on the loading platform.
  • the object of the invention is to propose a technical solution allowing ensure cold for the products presented on the loading platform optimum by avoiding as much as possible the loss of cold towards the top of the window.
  • a display case refrigerated of the type essentially comprising a tank mounted on a chassis containing a cold battery, a front window flap pivotally mounted to the front of the tank and a single loading platform substantially covering the tank opening surface, characterized in that the tank has a air deflector element to create a limited cold zone extending slightly above the products presented on the shelf loading.
  • the orientable deflector element for blowing consists of pivoting slats, for example three, arranged substantially between the rear inner wall of the tank and the rear end of the loading.
  • a refrigerated display case (1) essentially consists a tank (2) for example made of polyester reinforced with glass wool injected with polyurethane with reinforcements (13), an aluminum chassis (not shown), a horizontal loading platform (3) intended to receive products food (not shown), said loading tray covering substantially the opening surface of the tank (2).
  • the display case also comprises a domed front glass (4) fixed with swivel at the front of the tank for example on the outer wall before the tank by means of a horizontal pivot axis (5) joining the front window (4) and the tank (2). Any other means of pivoting may be used.
  • the display case (1) can also be fitted with side windows (not represented).
  • the refrigerated display case (1) further comprises a removable box (6), by example open towards the back of the tank and fixed sliding or pivoting below the loading platform (3); said removable box containing a cold battery (7) mounted in a known manner below the loading platform (3).
  • the tank (2) further comprises an orientable deflector element (8) located in upper part along the rear internal longitudinal wall of said tank to allow the creation of a limited cold zone (10).
  • the orientable blowing deflector element (8) is present in the form of strips (9), for example three in number, or horizontal fins, able to pivot about a horizontal axis parallel to the axis longitudinal of the tank (2), said strips being disposed substantially between the rear inner wall (2a) of the tank (2) at the upper level thereof and the rear end (3a) of the loading platform when it is in position horizontal.
  • the strips (9) are fixed at their ends to the inner side walls of the tank by means of pins (not shown) around which can pivot the slats (9) to be oriented.
  • the deflector element makes it possible to direct the flow of cold air (12) coming from cold coil (7) to create the limited cold zone encompassing the products in presentation extending slightly above these.
  • the adjustable deflector element for example by modifying the inclination of the slats (5), allows the maximum height (H) to be varied from the plane or to the upper surface of the loading platform (3) of the cold zone (10) depending on the nature and size of the products on display in the window.
  • This maximum height can be optimally around 13 cm.
  • the loading platform (3) is a platform seat (11) pivotally fixed between a horizontal position (A) and a inclined position (B) for example by means of castings (18) integral with the loading platform pivotally fixed by means of pins (14) with two arms of the pivot support (16) mounted symmetrically in part front of the inner wall of the tank (2).
  • the loading platform is provided with at least one jack hydraulic (15) articulated at one of its ends on an axis (16) integral with the arm of the support and at its other end to an axis (17) integral with the casting (18).
  • the positioning of the support arm at the front of the tank has little effect on the air flow (12) turning substantially from the rear towards the front of the tank above of the plateau and at the origin of the cold zone (10).
  • the tray of load can be lifted from the back of the display case making the bottom and walls of the tank (2) more easily accessible for cleaning especially when the folding window is in the open position.
  • the air flow is divided coming out of the cold battery in two parts.
  • the air flow leaving the cold coil is divided, for example in the ratio 1 / 2-2 / 3, in order to constitute respectively a low speed flow shown schematically by the arrows (19) and a high speed flow shown schematically by the arrows (20).
  • the flow (20) is channeled by a section (8 ') also forming a deflector for the slow flow (19), of a certain width at the outlet of the battery, which goes tapering to its outlet end (21) so as to reduce the flow towards the open surface of the box, pressing the flow at low speed below.
  • the substantially laminar flow of high speed therefore completely encloses the flow of lower speed, which contains product storage refrigeration in the low speed zone.
