Abstract

Portable refrigerating apparatus intended for the preservation of liquid foodstuffs or beverages. The invention relates to a small-sized refrigerating apparatus permitting the preservation of liquid products from -5 DEG C to +15 DEG C with approximately 1 DEG C precision. It consists of a compressor 1, a condenser 2 and a fan 3. The refrigerating part is composed of a receiver casing 4 at the centre of a fluid-tight vessel which contains a glycol-containing solution and which is surrounded by the evaporator coil; the whole unit is insulated with polyurethane foam 5. A miniature expansion tank 6, connected to the double casing, compensates for it. Incorporated into the covering 7 of the apparatus are a switch 8, an "on" warning light 9, a fault warning light 10, a regulating thermostat 11 and an alarm 12. The apparatus, according to the invention, is more particularly intended for the preservation of liquid foodstuffs during the feeding of patients (invalids) using a tube.

Description

La présente invention a pour but la conservation par réfrigération d'aliments liquides, de boissons ou autres produits conditionnés en bouteille d'un litre. Elle est plus particulièrement destinée au secteur hospitalier pour l'alimentation des malades par sonde. D'autres utilisations peuvent être aussi envisagées dans l'hôtellerie et la restauration. The present invention aims to preserve by refrigeration of liquid food, drinks or other products packaged in a liter bottle. It is more particularly intended for the hospital sector for feeding patients by tube. Other uses can also be considered in hotels and restaurants.

La technique antérieure faisait appel à un bac isotherme dans lequel était placé de la glace pilée ou sous forme de glaçons, avec les conséquences que l'on peut imaginer sur le maintien d'un aliment à une température incontrôlée pendant une assez longue durée, obligeant une attention soutenue quant à la qualité de la glace. The prior art used an insulated container in which was crushed ice or in the form of ice cubes, with the consequences that one can imagine on maintaining a food at an uncontrolled temperature for a fairly long period, requiring sustained attention to the quality of the ice.

Parmi les difficultés rencontrées dans l'élaboration d'un appareil frigorifique -le plus petit possible, comportant du matériel facilement disponible dans le commerce et susceptible de conserver un produit soit dans une seule bouteille d'un litre, soit directement- la principale résidait dans le fait que pour l'utilisation d'un compresseur de très petite puissance, les températures d'ébullition du fréon dans le serpentin évaporateur étaient trop basses pour que celui-ci soit placé en contact avec le carter récepteur, risquant ainsi d'entraîner le gel du liquide à conserver. I1 a donc fallu, pour pallier à cet inconvénient, fabriquer un container à double paroi, autour duquel a été soudé le tube en cuivre servant d'évaporateur.Le réservoir ainsi formé contient une solution glycolée qui a pour tâche d'accumuler et de transmettre progressivement le froid produit initialement. Among the difficulties encountered in the development of a refrigeration appliance - the smallest possible, comprising equipment readily available on the market and capable of preserving a product either in a single liter bottle or directly - the main one resided in the fact that for the use of a very low power compressor, the boiling temperatures of the freon in the evaporator coil were too low for it to be placed in contact with the receiver housing, thus risking the freezing of the liquid to be stored. To overcome this drawback, it was therefore necessary to manufacture a double-walled container, around which the copper tube used as an evaporator was welded. The reservoir thus formed contains a glycol solution which has the task of accumulating and transmitting gradually the cold initially produced.

Le principal avantage qui en découle se situe au niveau des températures obtenues celles-ci pouvant être sélectionnées dans. une gamme de -50C à +150C, avec une précision de 10C, au moyen du thermostat de régulation dont le bulbe se trouve en contact avec le mélange par l'intermédiaire d'un doigt de gant. Le même principe de montage a été retenu pour le thermostat d'alarme. La paroi extérieure de la partie réfrigérante a été recouverte d'une mousse de polyuréthane injectée et moulée, choisie pour ses qualités isolantes et sa facilité de mise en oeuvre.The main advantage which results from this lies in the temperatures obtained which can be selected in. a range of -50C to + 150C, with an accuracy of 10C, by means of the regulation thermostat, the bulb of which is in contact with the mixture via a thermowell. The same mounting principle was used for the alarm thermostat. The outer wall of the cooling part has been covered with an injected and molded polyurethane foam, chosen for its insulating qualities and its ease of use.

La seconde difficulté qu'il a fallu résoudre concernait le glycol qui, soumis à des variations de température, voyait son volume se modifier provoquant ainsi la mise en pression ou dépression de la double enveloppe. La solution à résidé en l'utilisation d'un petit vase d'expansion relié à la cuve étanche par un tube plastique, évitant les effets mécaniques précités. Souhaitant obtenir un appareil suffisament petit pour être facilement portable, la difficulté suivante consistait à condenser au maximum tous les éléments constituant la partie mécanique, haute pression et ventilation de l'invention. La solution adoptée a été la superposition des divers composants. A la base, se trouve le condenseur disposé à plat, surmonté du compresseur puis du ventilateur.Afin de faciliter les éventuels contrôles, des prises manométriques ont été placées sur les parties basse et haute pressions du circuit frigorifique. The second difficulty which had to be solved concerned the glycol which, subjected to temperature variations, saw its volume change thus causing the pressurization or depression of the double envelope. The solution resided in the use of a small expansion vessel connected to the sealed tank by a plastic tube, avoiding the aforementioned mechanical effects. Wishing to obtain a device small enough to be easily portable, the next difficulty consisted in condensing as much as possible all the elements constituting the mechanical, high pressure and ventilation part of the invention. The solution adopted was the superposition of the various components. At the base is the condenser placed flat, surmounted by the compressor and then the fan. To facilitate any checks, pressure sockets have been placed on the low and high pressure parts of the refrigeration circuit.

L'invention se présente sous la forme d'un parallélépipède rectangle comportant deux parties séparées par une cloison (23). On trouve d'une part, un compresseur de type hermétique de 1/12e de cheval (3), un ventilateur (16) placé au-dessus et un condenseur (4) au-dessous ; d'autre part, un carter cylindrique (13) aux dimensions d'une bouteille d'un litre, entouré d'une cuve étanche (7) remplie d'une solution glycolée avec à sa partie supérieure les orifices de deux doigts de gants (11) et (12), dans lesquels sont logés les bulbes des thermostats de régulation (17) et d'alarme (18). Un serpentin en cuivre de 1/4 de pouce (8) faisant fonction d'évaporateur, alimenté en fréon par le haut au moyen d'un capillaire (9) est soudé sur la paroi extérieure de la double enveloppe (7). Le tout est isolé avec de la mousse de polyuréthane (10) injectée et moulée.Un tube plastique (15) relie le réservoir de glycol (7) au mini-vase d'expansion (14) placé à la base de l'isolant. Des prises manométriques sont prévues sur le circuit basse (6) et haute (5) pressions afin de permettre des contrôles éventuels. L'ensemble des éléments repose sur un socle (1) qui au stade expérimental est fabriqué en bois, ce dernier étant étudié et conçu avec précision pour que tous les composants puissent être immobilisés. Un bottier (19) recouvre le tout ; on y trouve sur la face avant, un interrupteur "marche-arrêt" (20), un voyant indiquant la mise sous tension du compresseur (21) et un voyant d'alarme (22). Sur la partie supérieure de l'habillage, un orifice (25) au diamètre du carter récepteur (13) a été aménagé de même que le passage des boutons de réglage des thermostats de régulation (17) et d'alarme (18), ces trois éléments se trouvant incorporés à l'intérieur d'un logement (24) prévu pour recevoir aussi le câblage électrique. L'invention repose sur six pieds caoutchouc assurant un espace libre suffisant sous l'appareil permettant ainsi un passage aisé de l'air sous le socle à travers une découpe spécialement aménagée (2). I1 pourra être prévu un système de poignées facilitant le transport lors d'une fabrication en série.  The invention is in the form of a rectangular parallelepiped comprising two parts separated by a partition (23). On the one hand, there is a hermetic compressor of 1 / 12th horse (3), a fan (16) placed above and a condenser (4) below; on the other hand, a cylindrical casing (13) with the dimensions of a liter bottle, surrounded by a sealed tank (7) filled with a glycol solution with at its upper part the orifices of two glove fingers ( 11) and (12), in which the bulbs of the regulation (17) and alarm (18) thermostats are housed. A 1/4 inch copper coil (8) acting as an evaporator, supplied with freon from above by means of a capillary (9) is welded to the outer wall of the jacket (7). The whole is insulated with injected and molded polyurethane foam (10). A plastic tube (15) connects the glycol tank (7) to the mini expansion tank (14) placed at the base of the insulation. Pressure gauges are provided on the low (6) and high (5) pressure circuit to allow possible checks. All the elements rest on a base (1) which at the experimental stage is made of wood, the latter being studied and designed with precision so that all the components can be immobilized. A bootmaker (19) covers the whole; on the front panel, there is an "on / off" switch (20), an indicator light indicating that the compressor is on (21) and an alarm indicator (22). On the upper part of the casing, an orifice (25) with the diameter of the receiver housing (13) has been fitted out as well as the passage of the adjustment knobs for the regulation (17) and alarm (18) thermostats, these three elements being incorporated inside a housing (24) designed to also receive the electrical wiring. The invention is based on six rubber feet ensuring sufficient free space under the device, thus allowing easy passage of air under the base through a specially arranged cutout (2). I1 could be provided a handle system facilitating transport during mass production.
