Definitions

  • the present invention relates to a refrigeration unit provided with a mobile closure and screen device.
  • a refrigeration cabinet in particular that intended for the presentation for sale of foodstuffs such as a bin cabinet, a display cabinet, is generally open, that is to say provided with an opening which is not closed by a material barrier and gives free access to the exposed foodstuffs.
  • the aim of the present invention is to avoid these drawbacks, which makes it possible to produce a refrigerated cabinet provided with a movable closure device and a reflector screen having excellent efficiency in protecting this cabinet against rays. direct and thoughtful actions from the outside environment.
  • a refrigeration unit provided with a movable closure and screen device is characterized in that the movable closure and screen device comprises a reflector constituted by a piece of reflective material having the form of '' a gutter whose cross section has a curvature formed by an arc of a circle of radius which is determined as a function of the width of the food display surface and the height of the edge of this reflector vis-à-vis screw of this exhibition area.
  • the invention is applicable to any refrigerating cabinet intended for the presentation of foodstuffs for sale.
  • a refrigeration unit 1 taken as an exemplary embodiment of the invention is schematically illustrated in FIG. 1.
  • the refrigeration unit 1 is a unit intended for a presentation for sale of frozen products and ice creams.
  • the cabinet 1 comprises a lower part 2 produced in a similar manner to a known tray cabinet intended for frozen products and ice creams, and an upper part 3 supported by vertical uprights 4 fixed on the lower part 2, and intended mainly in housing a mobile closure and screen device 5 when the latter is in the high screen position.
  • the movable closure and screen device 5 comprises a low position or closed position where it closes the opening 11 of the lower part 2 to avoid any loss of cold, and a high position or screen position in order to allow free access to the foodstuffs exposed in the lower part 2 and to prevent as much as possible direct and reflected radiation from the external environment from reaching the foodstuffs.
  • the mobile closure and screen device 5 is suspended from the upper part 3 of the cabinet 1 by means of cables or belts 6 and idler support pulleys 7.
  • the cable or belts 6 which pass over the support pulleys 7 are, under the control of an electric motor 9 and its transmission shafts 10, wound on storage pulleys 8 when the device is raised from its low closed position to its high screen position, and unwound from these storage pulleys 8, when lowering this device from its high screen position to its low closed position.
  • the closure and screen device 5 In its high position or screen position, the closure and screen device 5 covers by its extent, an area of space above the part 2 of the cabinet where the food is exposed, separates the food by its presence of direct and / or reflected thermal radiation outside this covered area, and effectively prevents them from reaching these commodities.
  • the closure and screen device 5 comprises a reflector 12 and a rigid frame 15 supporting this reflector.
  • the reflector 12 of the closure and screen device 5 is constituted by a piece of reflective material having the shape of a gutter whose cross section has a curvature formed by an arc of a circle of radius R which is determined as a function of the width of the food display surface of the cabinet 1 and the height of the edge of this reflector 12 with respect to this display surface.
  • the width of the food display surface is delimited by points A and B and equal to d
  • the height with respect to this display surface AB where the edge of the reflector 12 is located in the high position is marked by points B and C and equal to h, C being vertical to B in other words BC perpendicular to AB
  • the angle formed by straight lines joining point C of the edge of the reflector 12 and respectively these delimiting points A and B of the width of the food display surface is equal to alpha
  • the reflector 12 is provided with a cross section having a curvature constituted by an arc delimited by the points D.
  • the efficiency of the closure and screen device 5 with reflector 12 makes it possible to obtain, compared with the devices of the known solutions, an energy saving greater than 20%.
  • the upper part 3 with its bandages or side plates 14 constitutes a housing for the closure and screen device 5 in the high position and serves as a shelf support. rage, decoration and information or advertising on products for sale and / or insured services.
  • the upper part 3 contains a system of tubes and / or light bulbs, not shown, which, in direct or reflected light, diffuse or in the form of a beam or spot, white, monochrome or full color, illuminates not only the food display surface in the lower part 2 but also the strips or side plates 14 made of materials chosen from transparent, translucent and opaque materials.
  • the reflector 12 is made of a material chosen from metals with a reflective surface, metallized reflective materials and other known reflective materials.
  • the reclector 12 consists of a single piece or an assembly of component parts having the same color or several assorted colors.
