Description

La présente invention a pour object un dispositif pour la fabrication de glace, avantageusement utilizable, grâce à son encombrement minimum, et à son rendement élevé, sur des moyens de locomotion, tels que des embarcations, des roulottes, et autres.The present invention relates to a device for the manufacture of ice, advantageously usable, thanks to its minimum size, and to its high efficiency, on means of locomotion, such as boats, trailers, and others.

Le dispositif suivant l'invention est du type dans lequel la glace est fabriquée dans au moins un récipient en gobelet, à axe essentiellement vertical, et avec son ouverture tournée vers le haut, dont la forme est telle à permettre le démoulage des petits blocs de glace fabriqués, ce récipient étant associé à l'évaporateur d'un circuit frigorigène, et étant destiné à recevoir chaque fois une quantité d'eau mesurée. Ce récipient en gobelet comporte des moyens de chauffage appropriés, mis en action pour une courte période, une fois que chaque petit bloc de glace a été fabriqué, afin de le détacher des parois du récipient, et de permettre le démoulage du même.The device according to the invention is of the type in which the ice is produced in at least one cup container, with an essentially vertical axis, and with its opening facing upwards, the shape of which is such as to allow the small blocks of mold to be removed from the mold. manufactured ice, this container being associated with the evaporator of a refrigerant circuit, and being intended to receive each time a measured quantity of water. This cup container has suitable heating means, activated for a short period, after each small block of ice has been manufactured, in order to detach it from the walls of the container, and to allow the release of the same.

Les dispositifs à glace de ce type présentent des avantages indiscutables, mais aussi des problèmes importants du point de vue de l'extraction de chaque petit bloc de glace du récipient respectif, problèmes qu'on résoud actuellement d'une manière plutôt empirique, par une opération tout-à-fait manuelle.Ice devices of this type have indisputable advantages, but also important problems from the point of view of the extraction of each small block of ice from the respective container, problems which are currently solved in a rather empirical manner, by a completely manual operation.

La présente invention vise à rémédier à cet inconvénient en proposant un dispositif à fabriquer de la glace, du type décrit ci-dessus, dans lequel l'éjection de chaque petit bloc de glace du récipient en gobelet respectif est mécanisée, des moyens de simple construction, préférablement à commande automatique, étant utilisés.The present invention aims to remedy this drawback by proposing an ice-making device, of the type described above, in which the ejection of each small block of ice from the respective cup container is mechanized, means of simple construction , preferably with automatic control, being used.

Suivant l'invention, les moyens d'éjection de chaque petit bloc de glace fabriqué comportent un organe de poussée, aménagé au fond du récipient en gobelet, et susceptible d'effectuer un mouvement axial ascendant le long de ce récipient, tel à provoquer l'éjection du petit bloc de glace situé au-dessus de cet organe, ainsi qu'un mouvement correspondant de descente dans sa position de repos.According to the invention, the means for ejecting each small block of ice produced comprise a thrust member, arranged at the bottom of the container in a cup, and capable of effecting an upward axial movement along this container, such as to cause the ejection of the small block of ice located above this organ, as well as a corresponding movement of descent into its rest position.

Le mouvement de cet organe de poussée peut être provoqué par n'importe quels moyens d'actionnement.The movement of this thrust member can be caused by any actuation means.

Dans une forme préférée de réalisation du dispositif à glace, suivant l'invention, cet organe de poussée est constitué par un piston, normalement logé à étanche de fluide dans la partie inférieure d'un récipient en gobelet cylindrique, le fond de ce récipient étant relié à une source de fluide sous pression, provoquant, par suite de la commande des moyens à vanne de contrôle respectifs, le mouvement ascendant du piston et, par conséquent, l'éjection du petit bloc de glace fabriqué. Le mouvement descendant successif du piston jusqu'au fond du récipient peut s'effectuer simplement par gravité, ou bien à l'aide de n'importe quels moyens d'actionnement. Dans le cas où ce fluide sous pression soit de l'eau, l'invention peut prévoir un conduit, reliant, par l'intermédiaire de moyens à vanne appropriés le fond du récipient en gobelet à son ouverture, l'eau précédemment introduite dans le récipient, au-dessous du piston pour l'élever, étant pompée, par ce piston même, pendant sa phase de descente, dans la partie supérieure du récipient, afin d'obtenir ainsi la quantité d'eau mesurée nécéssaire à la fabrication du petit bloc de glace successif.In a preferred embodiment of the ice-cream device, according to the invention, this pushing member consists of a piston, normally housed with fluid tightness in the lower part of a container in a cylindrical cup, the bottom of this container being connected to a source of pressurized fluid, causing, as a result of the control of the respective control valve means, the upward movement of the piston and, consequently, the ejection of the small block of ice produced. The successive downward movement of the piston to the bottom of the container can be carried out simply by gravity, or else using any actuation means. In the case where this pressurized fluid is water, the invention can provide a conduit, connecting, by means of suitable valve means, the bottom of the cup container to its opening, the water previously introduced into the container, below the piston to raise it, being pumped, by this piston itself, during its descent phase, in the upper part of the container, in order to thus obtain the quantity of water measured necessary for the manufacture of the small successive block of ice.

Les caractéristiques susdite et d'autres encore du dispositif pour la fabrication de glace suivant l'invention, ainsi que les avantages ressortant du même seront très clairement expliquées ci-dessous, grâce à la description detaillée des formes de réalisation preferées de ce dispositif, données à titre d'exemples non limitatifs, et représentées aux dessins annexés, dans lesquels:

  • La figure 1 est une vue schématique, partiellement en section, d'une première forme de réalisation d'un dispositif à fabriquer de la glace, suivant l'invention;
  • La figure 2 est une vue similaire d'une deuxième forme de réalisation de ce dispositif.
The aforementioned and other characteristics of the device for the manufacture of ice cream according to the invention, as well as the advantages arising from the same will be very clearly explained below, thanks to the detailed description of the preferred embodiments of this device, given by way of nonlimiting examples, and shown in the appended drawings, in which:
  • Figure 1 is a schematic view, partially in section, of a first embodiment of an ice-making device, according to the invention;
  • Figure 2 is a similar view of a second embodiment of this device.

Ainsi que représenté à la figure 1, un dispositif pour la fabrication de glace, suivant l'invention, comporte un récipient en gobelet 1, disposé verticalement, et présentant un corps tubulaire cylindrique 101 ouvert à son extrémité supérieure et se terminant à son extrémité inférieure par un culot 201. Ce récipient en gobelet 1 est destiné à recevoir chaque fois une quantité d'eau prédéterminée, qui sera convertie en un petit bloc de glace équivalent, le récipient susdit étant refroidi par l'évaporateur 2, y associé, d'un circuit frigorigène, dont le compresseur 3, le condenseur 4, et la soupape d'expansion à tube capillaire 5, sont représentés schématiquement.As shown in FIG. 1, a device for the production of ice cream, according to the invention, comprises a cup container 1, arranged vertically, and having a cylindrical tubular body 101 open at its upper end and ending at its lower end by a base 201. This cup container 1 is intended to receive each time a predetermined quantity of water, which will be converted into a small block of equivalent ice, the aforesaid container being cooled by the evaporator 2, associated therewith. a refrigerant circuit, including the compressor 3, the condenser 4, and the capillary tube expansion valve 5, are shown diagrammatically.

L'évaporateur 2 est, de préférence, du type à chemise cylindrique, cette chemise, indiquée par 102, étant formée entre le corps tubulaire 101 du gobelet 1 et un manchon 202 de plus grand diamètre, disposé coaxialement à l'extérieur du corps tubulaire susdit. A son extrémité supérieure, cette chemise 2 est fermée par un élément annulaire 302, alors que son extrémité inférieure est fermée par une bride 211 en saillie du culot 201.The evaporator 2 is preferably of the cylindrical jacket type, this jacket, indicated by 102, being formed between the tubular body 101 of the cup 1 and a sleeve 202 of larger diameter, arranged coaxially outside the tubular body above. At its upper end, this jacket 2 is closed by an annular element 302, while its lower end is closed by a flange 211 projecting from the base 201.

Le fluide frigorigène, provenant du tube capillaire 5, sera alimenté, à la partie inférieure de la chemise 102, par un serpentin hélicoidal 6 enroulé autour du manchon 202, en contact intime avec celui-ci, et sera fait sortir de l'extrémité supérieure de cette chemise.The refrigerant, coming from the capillary tube 5, will be supplied, at the lower part of the jacket 102, by a helical coil 6 wound around the sleeve 202, in intimate contact with the latter, and will be brought out of the upper end of this shirt.

Lorsque un petit bloc de glace a été fabriqué dans le récipient en gobelet 1, le tube capillaire 5 sera by-passé par l'ouverture d'une soupape 7, disposée en parallèle avec celui-ci, de sorte que le fluide frigorigène, renfermant un certain pouvoir calorifique, pourra chauffer pour une courte période, par le serpentin 6, le corps 101 du récipient en gobelet, le petit bloc de glace étant ainsi détaché des parois du gobelet, prêt pour son éjection du même.When a small block of ice has been made in the cup container 1, the capillary tube 5 will be bypassed by the opening of a valve 7, arranged in parallel therewith, so that the refrigerant, containing a certain calorific value, can heat for a short period, by the coil 6, the body 101 of the container in a cup , the small block of ice being thus detached from the walls of the cup, ready for its ejection of the same.

L'ensemble constitué par le récipient en gobelet 1 et par l'évaporateur à chemise 2, proprement destiné à la fabrication de la glace, est dûment calorifugé, et renfermé dans une boîte 8, pourvue à son extrémité supérieure d'un couvercle 208 présentant une ouverture évasée 218 en communication avec l'ouverture du gobelet 1.The assembly constituted by the cup container 1 and by the jacket evaporator 2, properly intended for making ice, is duly insulated, and enclosed in a box 8, provided at its upper end with a cover 208 having a flared opening 218 in communication with the opening of the cup 1.

Suivant l'invention, en vue de l'éjection de chaque petit bloc de glace fabriqué, on a pourvu, dans le récipient en gobelet 1, un piston 9 à étanche d'eau coulissant, normalement positionné à l'intérieur du culot 201 du récipient susdit. Du côté inférieur du piston 9 s'étend une tige 109 passant à travers d'un trou 301 dans le fond du gobelet 1, et logée dans son enveloppe respective 10, fixée au fond 108 de la boîte 8. L'extrémité libre de la tige 109 est pourvue d'une butée en goupille 209 établissant la position extrème de la course ascendante du piston 9.According to the invention, with a view to ejecting each small block of ice produced, a sliding water-tight piston 9, normally positioned inside the base 201 of the the above container. On the lower side of the piston 9 extends a rod 109 passing through a hole 301 in the bottom of the cup 1, and housed in its respective envelope 10, fixed to the bottom 108 of the box 8. The free end of the rod 109 is provided with a pin stop 209 establishing the extreme position of the upward stroke of the piston 9.

L'enveloppe 10 est reliée par un conduit 11 à une source d'eau sous pression P, et par un conduit 12 à l'ouverture du gobelet 1, ces conduits étant contrôlés par une vanne 13 à deux positions, coupant alternativement l'un ou l'autre de ces conduits.The casing 10 is connected by a pipe 11 to a source of pressurized water P, and by a pipe 12 to the opening of the cup 1, these pipes being controlled by a two-position valve 13, alternately cutting one either of these conduits.

Après la fabrication d'un petit bloc de glace et le chauffage, de la manière susdite, des parois du récipient 1, la vanne 13 est mise dans sa position opérative représentée à la figure 1, afin de couper le conduit 12 et d'ouvrir le conduit 11. Par conséquent, par l'enveloppe 10 et le trou inférieur 301, l'eau sous pression penètre dans le gobelet 1, au-dessous du piston 9, forçant ainsi ce piston à monter jusqu'à l'ouverture du gobelet et à éjecter le petit bloc de glace situé au-dessus du piston même. L'ouverture 218 de la boîte 8 peut être pourvue sur son bord de moyens de guidage (non représentés) pour contrôler la chute du petit bloc de glace.After the manufacture of a small block of ice and the heating, in the above-mentioned manner, of the walls of the container 1, the valve 13 is put in its operating position shown in FIG. 1, in order to cut the conduit 12 and open the conduit 11. Consequently, through the casing 10 and the lower hole 301, the pressurized water enters the cup 1, below the piston 9, thus forcing this piston to rise until the opening of the cup and eject the small block of ice located above the piston itself. The opening 218 of the box 8 can be provided on its edge with guide means (not shown) to control the fall of the small block of ice.

Après la phase d'éjection susdite, la vanne 13 est mise dans son autre position opérative, dans laquelle le conduit 11 sera fermé, et le conduit 12 sera ouvert. Par conséquent, le piston 9 descend par gravité jusqu'au culot 201, pompant ainsi l'eau, située au-dessous du même, dans la partie supérieure du gobelet 1, jusqu'à le remplir. Le dispositif suivant l'invention est donc prêt pour la fabrication d'un autre petit bloc de glace.After the abovementioned ejection phase, the valve 13 is put in its other operative position, in which the duct 11 will be closed, and the duct 12 will be open. Consequently, the piston 9 descends by gravity to the base 201, thereby pumping the water, located below the same, in the upper part of the cup 1, until it fills it. The device according to the invention is therefore ready for the manufacture of another small block of ice.

L'eau sous pression, nécéssaire à l'actionnement du piston 9, sera débitée du réseau hydraulique normal, ou par une pompe, ou bien d'une caisse à eau pressurisée.The pressurized water, necessary for actuating the piston 9, will be supplied from the normal hydraulic network, or by a pump, or else from a pressurized water box.

Le cas échéant, on peut prévoir d'insérer un régulateur de pression (non représenté) entre la source d'alimentation P et la vanne 13. Il est possible, d'automatiser complètement, à l'aide d'un dispositif temporisateur (non représenté), toutes les phases operatives successives du dispositif à glace suivant l'invention.If necessary, provision may be made to insert a pressure regulator (not shown) between the power source P and the valve 13. It is possible to automate completely, using a timer device (not shown), all the successive operational phases of the ice device according to the invention.

La figure 2 représente une deuxième forme de réalisation du dispositif à glace suivant l'invention, dans lequel l'éjection de chaque petit bloc de glace s'effectue au moyen d'une tige de poussée 14 susceptible de s'engager en toute sa longuer dans le gobelet 1, par suite de sa pénétration à étanche d'eau dans le même, par un trou 401 dans le fond de ce gobelet. L'extrémité inférieure de cette tige 14 est fixée à un piston 15, ces deux éléments étant logés dans un cylindre 16 aménagé au-dessous de la boîte 8 contenant les éléments de congélation 1 et 2. A la plaque de fond 116 du cylindre 16 sont connectés, par l'intermédiaire de la vanne 13, les conduits 11 et 12 susdits.FIG. 2 represents a second embodiment of the ice device according to the invention, in which the ejection of each small block of ice takes place by means of a push rod 14 capable of engaging in all its length in the cup 1, as a result of its watertight penetration into the same, through a hole 401 in the bottom of this cup. The lower end of this rod 14 is fixed to a piston 15, these two elements being housed in a cylinder 16 arranged below the box 8 containing the freezing elements 1 and 2. At the bottom plate 116 of the cylinder 16 are connected, via the valve 13, the conduits 11 and 12 above.

Même dans cette forme de réalisation, la course ascendante de l'ensemble tige-piston 14, 15 s'effectue grâce à la poussée de l'eau sous pression, ce qui provoque l'éjection du petit bloc de glace. Ensuite, cet ensemble 14, 15 va descendre par gravité dans sa position de repos, pompant, pendant sa course descendante, la quantité d'eau inférieure mesurée dans la partie supérieure du gobelet 1. Bien entendu, ces phases operatives dépendent de la commutation de la vanne d'alimentation commandée 13, comme expliqué ci-dessus.Even in this embodiment, the upward stroke of the rod-piston assembly 14, 15 is effected by the push of the pressurized water, which causes the small block of ice to be ejected. Then, this assembly 14, 15 will descend by gravity into its rest position, pumping, during its downward stroke, the amount of lower water measured in the upper part of the cup 1. Of course, these operational phases depend on the switching of the controlled supply valve 13, as explained above.

Dans cette deuxième forme de réalisation, l'utilisation d'une tige de poussée permet l'emploi d'un récipient de n'importe quelle forme, par exemple, tronconique, hémisphérique, en tronc de pyramide, pourvu-que cette forme soit telle à permettre le démoulage de chaque petit bloc de glace.In this second embodiment, the use of a push rod allows the use of a container of any shape, for example frustoconical, hemispherical, in a pyramid trunk, provided that this shape is such as to allow the release of each small block of ice.

Dans ces deux formes de réalisation, ainsi que décrites ci-dessus, l'organe de poussée est susceptible d'effectuer sa course descendante non seulement par gravité, mais aussi par effet de n'importe quels moyens d'actionnement.In these two embodiments, as described above, the thrust member is capable of effecting its downward travel not only by gravity, but also by the effect of any actuation means.

On peut, bien sûr, prévoir dans un dispositif à glace, suivant l'invention, une pluralité de récipients de congélation en batterie, chacun pourvu de son organe d'éjection respectif, ces récipients étant associés à un évaporateur commun.One can, of course, provide in an ice device, according to the invention, a plurality of freezing containers in battery, each provided with its respective ejection member, these containers being associated with a common evaporator.

De ce que l'on vient de décrire, il ressort très clairement qu'un dispositif pour la fabrication rapide de glace, suivant l'invention, présente, au regard des dispositifs connus de ce type, bien des avantages, parmi lesquels:
- mécanisation complète de la phase d'éjection des petits blocs de glace fabriquès;
- possibilité d'automatiser la phase opérative susdite;
- modique dépense d'eau et d'énergie;
- construction simple, encombrement minimum;
- possibilité d'utiliser l'eau contenue dans une caisse pressurisée.From what has just been described, it is very clear that a device for the rapid production of ice, according to the invention, has, with regard to known devices of this type, many advantages, among which:
- complete mechanization of the ejection phase of the small blocks of ice produced;
- possibility of automating the above operational phase;
- low expenditure of water and energy;
