Description

La présente invention concerne une vitrine réfrigérée à système de réception et d'évacuation de liquides et exsudats.The present invention relates to a refrigerated display case with a system for receiving and discharging liquids and exudates.

Les vitrines réfrigérées connues comprennent habituellement deux types de vitrines, un type de vitrine à cuve isolante dont la cuve qui ferme la partie inférieure permet d'éviter des pertes de froid par le bas, de loger des systèmes de production et de circulation de froid, et de recueillir des eaux de nettoyage et des exsudats des produits exposés dans son enceinte sur des étagères et un type de vitrine à chargement avant où les produits sont présentés d'une part sur des étagères fixées dans la partie supérieure de la vitrine et d'autre part sur des chariots ou palettes mis en place par le côté avant de la vitrine, dans la partie inférieure de son enceinte. Dans une vitrine réfrigérée du type à cuve isolante, la cuve est pourvue d'un système d'évacuation de liquides comprenant habituellement deux bondes formées dans les zones des deux extrémités de cette cuve, deux siphons et des conduites de drainage à faible pente raccordés à ces bondes pour amener les liquides recueillis jusqu'à une canalisation d'évacuation générale. Les eaux de nettoyage s'évacuent facilement à travers ces siphons et conduites de drainage mais les exsudats forment habituellement des amas plus ou moins visqueux qui s'accrochent aux parois de ces siphons et conduites de drainage à faible pente et risquent de les obstruer facilement. Par ailleurs, dans ces vitrines connues, les siphons et conduites de drainage montés dans des espaces exigus en dessous de leur cuve sont seulement accessibles jusqu'au ras du sol. Une telle disposition rend difficile leur entretien et notamment leur nettoyage en cas d'obstruction d'écoulement. Les vitrines réfrigérées connues du type à chargement avant sont souvent dépourvues de système de réception et d'évacuation de liquides et exsudats. Certaines d'entre elles comprennent cependant sur le long de leur paroi arrière, une gouttière horizontale fixe pour recueillir des liquides à la manière des cuves des vitrines réfrigérées du type à cuve isolante. Cette gouttière horizontale fixe comprend à ses deux extrémités deux siphons et des conduites de drainage pour amener les liquides recueillis jusqu'à une canalisation d'évacuation générale. Ce système de réception et d'évacuation de liquides et exsudats comporte les mêmes risques d'obstruction d'écoulement que ceux du système d'évacuation de liquide des vitrines réfrigérées connues du type à cuve isolante, rappelées dans un paragraphe précédent.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. In a refrigerated display case of the insulating tank type, 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. Furthermore, in these known showcases, 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.

La présente invention ayant pour but d'éviter les inconvénients ci-dessus, permet de réaliser une vitrine réfrigérée économique munie d'un système de réception et d'évacuation de liquides et exsudats facilement adaptable pour former soit un système individuel efficace et simple en structure soit un système efficace et simple en structure commun à plusieurs vitrines assemblées.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.

L'invention a également pour objet une vitrine réfrigérée ayant un système de réception et d'évacuation de liquides et exsudats présentant peu de risque d'obstruction d'écoulement, provoquée par des exsudats.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.

Selon l'invention, une vitrine réfrigérée à système de réception et d'évacuation de liquides et exsudats, ayant dans sa partie inférieure, une paroi fixe de réception d'eau de dégivrage et une plaque amovible de ramassage de liquides, est caractérisée en ce que le système de réception et d'évacuation de liquides et d'exsudats comprend au-dessous des bords longitudinaux voisins de la paroi fixe de réception d'eau de dégivrage et de la plaque amovible de ramassage de liquides, au moins une gouttière ajustable en hauteur, réglable et orientable en pente ou inclinaison vis-à-vis de l'horizontale et vers l'une au choix des deux extrémités de cette gouttière.According to the invention, 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, is characterized in that that 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.

Une vitrine réfrigérée connue du type à cuve isolante 1 illustrée schématiquement et partiellement dans la figure 1 comprend des parois fixe thermiquement isolantes 2,3,3a dans ses parties supérieure, arrière et latérale, une cuve isolante fixe 4 dans sa partie inférieure, des étagères 5 et un plateau 6 pour la présentation des produits à la vente. Le froid est produit par un système frigorifique 7 et l'air froid est mis en circulation dans la vitrine 1 par un système de ventilation 8. Les eaux de dégivrage et de nettoyage et les exsudats des produits exposés dans les étagères 5 et plateau 6 sont recueillies par la cuve isolante 4 et rassemblées dans le fond et notamment dans les zones des deux extrémités de cette cuve 4 où sont formées deux bondes 9,10 pour leur évacuation à l'extérieur de la vitrine. Dans cette vitrine réfrigérée 1, un système individuel d'évacuation de liquides comprend deux siphons 11 et 12 reliés à une conduite commune de drainage 13 jusqu'à une canalisation d'évacuation générale 14.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. In this refrigerated display case 1, 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.

Dans un ensemble connu 25 formé de trois vitrines réfrigérées connues 1 assemblées en ligne, un système commun d'évacuation de liquides comprend six siphons 11,12,15,16,17,18 respectivement reliés par une de leurs extrémités aux bondes 9,10,19,20,21,22 et par leur deuxième extrémité à travers deux conduites communes de drainage 13 et 23 à une canalisation d'évacuation générale 14.In a known assembly 25 formed of three known refrigerated display cases 1 assembled in line, 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.

Ces systèmes individuels ou communs d'évacuation de liquides sont, dans la vitrine réfrigérée connue 1 ou dans l'ensemble connu 25, montés dans des espaces exigus situés entre leurs cuves isolantes 4 et le sol, dont l'accès presque au ras du sol est habituellement difficile. Pour cette raison, des opérations de nettoyage ou d'entretien et de réparation de ces systèmes individuels ou communs d'évacuation de liquides de ces vitrines réfrigérées connus 1 ou ensemble connu 25 sont généralement pénibles et longues.These individual or common systems for evacuating liquids are, in the known refrigerated display case 1 or in the known assembly 25, mounted in confined spaces situated between their insulating tanks 4 and the ground, the access of which is almost flush with the ground. is usually difficult. For this reason, cleaning or maintenance and repair operations of these individual or common systems for evacuating liquids from these known refrigerated display cases 1 or known assembly 25 are generally tedious and time-consuming.

Par ailleurs, ces systèmes d'évacuation de liquides de ces vitrines 1 ou ensemble 25 connus comportent généralement un nombre relativement grand de siphons et de conduites de drainage, ce qui rend encore leur entretien long et coûteux.Furthermore, 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.

La solution apportée par l'invention permet d'éviter ces inconvénients.The solution provided by the invention avoids these drawbacks.

Une vitrine réfrigérée 26 réalisée selon l'invention illustrée schématiquement et partiellement dans les figures 3 et 4 comprend dans ses parties supérieure et arrière et dans sa partie frontale inférieure, des parois fixes thermiquement isolantes 28,29, dans ses parties latérales des parois amovibles 30, et dans son enceinte un système de production de froid 31 et un système de circulation d'air froid 32, montés dans un espace vertical 33 d'une gaine d'air définie par la paroi arrière 28 et une paroi de séparation 34 qui supporte des étagères 35. La vitrine réfrigérée 26 comprend dans la partie inférieure de son enceinte, successivement de haut en bas, un plateau amovible incliné, le plus bas, de présentation de produits 36, une plaque inclinée amovible de ramassage de liquide 37 et une paroi fixe inclinée de réception d'eau de dégivrage 38. Dans l'exemple illustré le plateau amovible 36 est monté incliné vers l'avant entre la paroi de séparation 34 et une grille amovible d'aspiration d'air froid 39. La paroi fixe de réception d'eau de dégivrage 38 est disposée inclinée vers l'avant le long d'une ligne horizontale, contre la paroi arrière 28 de la vitrine et la plaque de ramassage de liquide 37 est montée amovible inclinée vers l'arrière entre cette paroi de réception d'eau de dégivrage 38 et la paroi inférieure frontale 29 de la vitrine. La vitrine réfrigérée 26 comprend au niveau de sa paroi de réception d'eau de dégivrage 38 et de sa plaque de ramassage de liquides, un système de réception et d'évacuation de liquides et d'exsudats 40.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. In the example illustrated 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.

Selon une caractéristique importante, dans la vitrine réfrigérée 26, le système de réception et d'évacuation de liquides et d'exsudats 40 comprend au-dessous des bords longitudinaux voisins 41 et 42 de la paroi de réception d'eau de dégivrage 38 et de la plaque de ramassage de liquides 37, au moins une gouttière 44 ajustable en hauteur, réglable et orientable en pente ou inclinaison vis-à-vis de l'horizontale et vers l'une au choix des deux extrémités de cette gouttière.According to an important characteristic, in the refrigerated display case 26, 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.

La gouttière 44 est constituée d'éléments standards assemblables à savoir principalement des profils-gouttières 45 formés de pièces allongées semi-cylindriques, des pièces de jonction 46 constituées de raccords maintenant des profils-gouttières assemblés bout à bout, des fonds-gouttières 47 constitués d'embouts fermant des extrémités des profils-gouttières, et des pièces de dérivation ou naissance-gouttière 48 constituées de raccords munis d'un goulet tubulaire de sortie, pour des profils-gouttières.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.

La gouttière 44 est maintenue par des crochets 49 montés réglables en hauteur, le long de trous allongés ou boutonnières 50 des supports fixes 51 rendus solidaires de la paroi fixe de réception d'eau de dégivrage 38.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.

Grâce aux caractéristiques d'ajustement en hauteur des gouttières, de réglage et d'orientation de pente de ces gouttières, et de jonction de ces gouttières, l'architecture du système de réception et d'évacuation de liquides et d'exsudats 44 dans une vitrine réfrigérée 26 peut être réduite à une structure simple comportant un seul siphon 53 connecté entre une naissance-gouttière ou pièce de dérivation 48, et une canalisation d'évacuation générale 55, et le cas échéant une seule conduite de drainage 54, qui prolonge ce siphon 53.Thanks to the characteristics of height adjustment of the gutters, of adjustment and slope orientation of these gutters, and of junction of these gutters, 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.

Il en est de même dans un ensemble 56 formé de trois vitrines réfrigérées 26 assemblées bout à bout en ligne (figure 3), dans lequel les parois latérales amovibles 30 des extrémités en jonction indiquées en 57,58 des vitrines réfrigérées 26 sont enlevées, l'architecture du système de réception et d'évacuation de liquides et d'exsudats 44 est réduite à une structure simple comportant un seul siphon 53 et le cas échéant une seule conduite de drainage 54 qui prolonge ce siphon 53.It is the same in an assembly 56 formed of three refrigerated display cases 26 assembled end to end in line (FIG. 3), in which the removable side walls 30 of the junction ends indicated at 57.58 of the refrigerated display cases 26 are removed, l the architecture of the system for receiving and evacuating liquids and exudates 44 is reduced to a simple structure comprising a single siphon 53 and if necessary a single drainage pipe 54 which extends this siphon 53.

Selon une autre caractéristique, dans la vitrine réfrigérée 26, le système de réception et d'évacuation de liquides et d'exsudats 44 comprend un réceptacle amovible d'exsudats 60 disposé sur la plaque de ramassage de liquides 37, en dessous du bord bas du plateau le plus bas amovible incliné de présentation de produit 36.According to another characteristic, in the refrigerated display case 26, 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.

Dans l'exemple illustré, le réceptacle amovible d'exsudats 60 est disposé en dessous de la grille amovible d'aspiration d'air froid 39 et du bord frontal bas du plateau le plus bas amovible incliné vers l'avant de présentation de produits 36. Les liquides et notamment les exsudats des produits entreposés dans les étagères supérieures 35 et le plateau 36 qui sont recueillis par le plateau le plus bas 36, s'écoulent sur la surface inclinée de ce dernier, vers le bord frontal bas de ce plateau et tombent dans le réceptacle 60 et y sont retenus. Une vidange adéquate de ce réceptacle amovible d'exsudats 60, facilitée par une amovibilitée organisée de la grille d'aspiration d'air froid 39 et du plateau 36, permet d'empêcher efficacement les exsudats recueillis de parvenir à la gouttière 44 et aux siphon 53 et conduite de drainage 54, et d'éviter de ce fait les ennuyeuses obstructions d'écoulement de ces derniers, habituellement rencontrées dans des vitrines réfrigérées connues.In the example illustrated, 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 The liquids and in particular the exudates of the products stored in the upper shelves 35 and the tray 36 which are collected by the lower tray 36, flow on the inclined surface of the latter, towards the bottom front edge of this tray and fall into receptacle 60 and are retained there. 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.
