Definitions

  • the present invention relates to a refrigerated display case with a system for receiving and discharging liquids and exudates.
  • Known refrigerated display cases usually include two types of display cases, a type of insulated tank display case whose tank which closes the lower part makes it possible to avoid losses of cold from below, to house cold production and circulation systems, and collect cleaning water and exudates of the products exposed in its enclosure on shelves and a type of front loading display case where the products are presented on the one hand on shelves fixed in the upper part of the display case and on the other hand on trolleys or pallets set up by the front side of the showcase, in the lower part of its enclosure.
  • the tank is provided with a liquid evacuation system usually comprising two bungs formed in the areas of the two ends of this tank, two siphons and shallow drainage pipes connected to these bumps to bring the collected liquids to a general evacuation pipe.
  • the cleaning water is easily evacuated through these siphons and drainage pipes, but the exudates usually form more or less viscous clumps which cling to the walls of these siphons and drainage pipes with a slight slope and risk clogging them easily.
  • the siphons and drainage pipes mounted in cramped spaces below their tank are only accessible to the ground. Such an arrangement makes it difficult to maintain them and in particular to clean them in the event of flow obstruction.
  • the known refrigerated display cases of the front loading type are often lacking a system for receiving and discharging liquids and exudates. Some of them however include along their rear wall, a fixed horizontal gutter for collecting liquids in the manner of the tanks of refrigerated display cases of the insulating tank type.
  • This fixed horizontal gutter includes at its two ends two siphons and drainage pipes to bring the collected liquids to a general evacuation pipe.
  • This system for receiving and evacuating liquids and exudates involves the same risks of flow obstruction as those of the liquid evacuation system of known refrigerated display cases of the insulating tank type, recalled in a previous paragraph.
  • the aim of the present invention is to avoid the above drawbacks, which makes it possible to produce an economical refrigerated display case provided with a system for receiving and discharging liquids and exudates that is easily adaptable to form either an efficient and simple individual system in structure. or an efficient and simple system in structure common to several assembled showcases.
  • the invention also relates to a refrigerated display case having a system for receiving and evacuating liquids and exudates presenting little risk of flow obstruction caused by exudates.
  • a refrigerated display case with a system for receiving and discharging liquids and exudates having in its lower part a fixed wall for receiving defrosting water and a removable plate for collecting liquids
  • the system for receiving and discharging liquids and exudates comprises, below the longitudinal edges adjacent to the fixed wall for receiving defrosting water and the removable plate for collecting liquids, at least one adjustable gutter in height, adjustable and adjustable in slope or inclination with respect to the horizontal and towards one as desired of the two ends of this gutter.
  • a known refrigerated display case of the insulating tank type 1 illustrated diagrammatically and partially in FIG. 1 comprises fixed thermally insulating walls 2,3,3a in its upper, rear and lateral parts, a fixed insulating tank 4 in its lower part, shelves 5 and a tray 6 for the presentation of products for sale.
  • the cold is produced by a refrigeration system 7 and the cold air is circulated in the display case 1 by a ventilation system 8.
  • the defrosting and cleaning waters and the exudates of the products exposed in the shelves 5 and tray 6 are collected by the insulating tank 4 and gathered at the bottom and in particular in the areas of the two ends of this tank 4 where two bungs 9, 10 are formed for their evacuation outside the display case.
  • a individual liquid evacuation system comprises two siphons 11 and 12 connected to a common drainage pipe 13 up to a general evacuation pipe 14.
  • a common system for discharging liquids comprises six siphons 11,12,15,16,17,18 respectively connected by one of their ends to the bungs 9,10 , 19,20,21,22 and by their second end through two common drainage pipes 13 and 23 to a general evacuation pipe 14.
  • these systems for evacuating liquids from these known display cases 1 or set 25 generally comprise a relatively large number of siphons and drainage pipes, which again makes their maintenance long and costly.
  • a refrigerated display case 26 produced according to the invention illustrated diagrammatically and partially in FIGS. 3 and 4 comprises in its upper and rear parts and in its lower front part, thermally insulating fixed walls 28, 29, in its lateral parts removable walls 30 , and in its enclosure a cold production system 31 and a cold air circulation system 32, mounted in a vertical space 33 of an air duct defined by the rear wall 28 and a partition wall 34 which supports shelves 35.
  • the refrigerated display case 26 comprises in the part lower of its enclosure, successively from top to bottom, a tilted removable tray, the lowest, for product presentation 36, a removable inclined plate for collecting liquid 37 and a fixed inclined wall for receiving defrost water 38.
  • the removable plate 36 is mounted inclined forward between the partition wall 34 and a removable grid for cold air suction 39.
  • the fixed wall for receiving defrost water 38 is disposed inclined towards the 'front along a horizontal line, against the rear wall 28 of the display case and the liquid collecting plate 37 is mounted removably inclined rearwards between this wall for receiving defrosting water 38 and the bottom front wall 29 of the window.
  • the refrigerated display case 26 comprises, at its wall for receiving defrosting water 38 and its liquid collecting plate, a system for receiving and evacuating liquids and exudates 40.
  • the system for receiving and discharging liquids and exudates 40 comprises below the adjacent longitudinal edges 41 and 42 of the wall for receiving defrosting water 38 and the liquid collecting plate 37, at least one gutter 44 adjustable in height, adjustable and orientable in slope or inclination with respect to the horizontal and towards one as desired of the two ends of this gutter.
  • the gutter 44 is made up of standard elements which can be assembled, namely mainly gutter profiles 45 formed from elongated semi-cylindrical parts, junction pieces 46 made up of connectors holding gutter profiles assembled end to end, gutter bottoms 47 made up end fittings closing the ends of the gutter profiles, and branch or birth-gutter parts 48 consisting of fittings provided with a tubular outlet neck, for gutter profiles.
  • the gutter 44 is held by hooks 49 mounted adjustable in height, along elongated holes or buttonholes 50 of the fixed supports 51 made integral with the fixed wall for receiving defrosting water 38.
  • the architecture of the system for receiving and discharging liquids and exudates 44 in a refrigerated display case 26 can be reduced to a simple structure comprising a single siphon 53 connected between a gutter or diversion piece 48, and a general evacuation pipe 55, and if necessary a single drainage pipe 54, which extends this siphon 53.
  • the system for receiving and evacuating liquids and exudates 44 comprises a removable receptacle for exudates 60 disposed on the liquid collecting plate 37, below the bottom edge of the lower inclined removable product presentation tray 36.
  • the removable exudate receptacle 60 is disposed below the removable cold air suction grid 39 and the bottom front edge of the removable bottom shelf inclined towards the front for presenting products 36
  • Adequate emptying of this removable exudate receptacle 60 facilitated by an organized detachability of the cold air suction grid 39 and of the plate 36, makes it possible to effectively prevent the exudates collected from reaching the gutter 44 and the siphon 53 and drainage pipe 54, and to avoid this fact annoying flow obstructions of the latter, usually encountered in known refrigerated display cases.
