Abstract

The well insulated box body (10) is subdivided by vertical partitions (6), leaving circulation gaps (7) at the foot. The top 25 % of the interior (8) is undivided, giving clear hand access to the contents without raising the lid (11) very high. Access is further improved by chamfering one long edge (9). Temperature rise while the lid is raised is further limited by side barriers (5). The insulated lid (11), resting on a foam seal on the box top, holds dry ice, under an access cover (4), in a central compartment communicating with the box interior through an adjustable rotary or sliding vent (3). USE/ADVANTAGE - For seaside ice-cream vendors, picnics, pleasure boats, etc. Even with frequent opening, temperature is maintained at about -10 deg. C. for several hours.

Description

GLACIERE A MAINTIEN ET REGULATION DE TEMPERATURE
La présente invention permet de conserver une température négative dans une glacière pendant un temps voulu avec une consommation de carboglace (C02) ou autre accumulateur de froid minime.HOLDING COOLER AND TEMPERATURE REGULATION
The present invention makes it possible to maintain a negative temperature in a cooler for a desired time with a consumption of dry ice (C02) or other minimal cold accumulator.

On trouve sur le marché des glacières dites de "camping" qui sont constituées de double cuve en plastic de type P.V.C. We find on the market so-called "camping" coolers which consist of double plastic vats of the P.V.C. type.

souple avec un remplissage partiel de polystyrène non solidaire des parois.flexible with partial filling of polystyrene not attached to the walls.

II y a perte de froid par effet - de déformation, donc effet de pompage des doubles parois de la cuve. There is a loss of cold by deformation effect, therefore the pumping effect of the double walls of the tank.

La fermeture est constituée d'un capot creux contenant de l'air, donc même phénomène de perte par pompage. The closure consists of a hollow cover containing air, therefore the same phenomenon of loss by pumping.

Le dispositif, selon l'invention, permet de conserver une température de congélation par une réserve de froid dans l'épaisseur du capot (1) sous forme de carboglace (C02 à l'état solide à -80 C) par un système de plaque coulissante ou tournante (2) et ajourée (3) de manière à créer une ouverture maximale ou une fermeture totale avec le fond du compartiment réservoir du'capot. The device according to the invention makes it possible to maintain a freezing temperature by a cold reserve in the thickness of the cover (1) in the form of dry ice (C02 in solid state at -80 C) by a plate system sliding or rotating (2) and perforated (3) so as to create a maximum opening or a total closure with the bottom of the tank compartment of the hood.

Ce système permet de moduler la température libérée par la réserve de froid se trouvant dans le capot et fermée par un couvercle (4). This system makes it possible to modulate the temperature released by the cold reserve located in the cover and closed by a cover (4).

Le fond du réservoir de carboglace peut être isolé de manière à économiser le froid pour en disposer au moment le plus opportun. The bottom of the dry ice tank can be insulated so as to save cold so that it is available at the most convenient time.

Le capot est muni d'un dispositif de deux plaques latérales (5) qui empêchent les turbulences d'air extérieures de rentrer dans la glacière au moment de l'ouverture. The hood is fitted with a device with two side plates (5) which prevent outside air turbulence from entering the cooler when it is opened.

L'intérieur peut être divisé en compartiments (6) de dimensions réglables avec un intervalle (7) entre le fond de la glacière et le bas des plaques, formant les compartiments, afin de laisser circuler le froid entre ceux-ci.  The interior can be divided into compartments (6) of adjustable dimensions with an interval (7) between the bottom of the cooler and the bottom of the plates, forming the compartments, in order to allow the cold to circulate between them.

Lorsqu'il s'agit de glacières d'une certaine hauteur1 il est recommandé de laisser 1/4 de la hauteur (8) sans cloison de façon à ce que la main plongée au fond de la glacière n'oblige qu'une ouverture minimale du capot. In the case of coolers of a certain height1 it is recommended to leave 1/4 of the height (8) without partition so that the hand plunged into the bottom of the cooler requires only a minimum opening of the hood.

Pour faciliter davantage cette ouverture minimale, un chanfrein (9) comme indiqué sur le dessin, permet d'améliorer cette ouverture minimale tout en accédant au fond. To further facilitate this minimum opening, a chamfer (9) as shown in the drawing, improves this minimum opening while accessing the bottom.

L'assemblage des plaques constituant la glacière, la pose des tissus de verre -pour la rigidité- et toutes les faces qui doivent recevoir des agents chimiques, doivent être protégées par un film de résine époxy compatible avec le polystyrène. The assembly of the plates constituting the cooler, the installation of glass fabrics - for rigidity - and all the faces which must receive chemical agents, must be protected by a film of epoxy resin compatible with polystyrene.

Toutes les parties exposées au soleil de l'ensemble capotglacière, ainsi que l'intérieur de la glacière, sont ou peuvent être recouvertes d'un film réfléchissant. All the parts exposed to the sun of the cooler hood assembly, as well as the interior of the cooler, are or can be covered with a reflective film.

Le contrôle de température s'effectue par un thermomètre à affichage digital avec une sonde reliée par un fil pour indiquer la température intérieure de la glacière (le A de lecture est de +70"C à -50"C).  The temperature is controlled by a digital display thermometer with a probe connected by a wire to indicate the interior temperature of the cooler (the reading A is from +70 "C to -50" C).

Le dispositif, selon l'invention, est particulièrement destiné à la vente de glaces sur les plages qui oblige à conserver une température de congélation aux alentours de -10 C pendant plusieurs heures malgré les ouvertures et fermetures fréquentes que nécessite la vente au détail d'un grand nombre de glaces par jour.  The device according to the invention is particularly intended for the sale of ice creams on the beaches which requires keeping a freezing temperature around -10 C for several hours despite the frequent openings and closings required by the retail sale of a large number of ice creams per day.
