Description

La présente invention concerne un appareil de réfrigération comprenant un bac à glaçons.The present invention relates to a refrigeration apparatus comprising an ice cube tray.

Elle concerne également un appareil électroménager, et de préférence un réfrigérateur, équipé d'un bac à glaçons conforme à l'invention.It also relates to an appliance, and preferably a refrigerator, equipped with an ice cube tray according to the invention.

De manière générale, la présente invention concerne les appareils de réfrigération domestiques dans lesquels une zone de congélation n'est pas prévue.In general, the present invention relates to domestic refrigeration apparatus in which a freezing zone is not provided.

On connaît d'une part des bacs comprenant des logements pour la formation de glaçons et des cavités contenant un liquide eutectique.There are known on the one hand trays comprising housing for the formation of ice cubes and cavities containing a eutectic liquid.

Ce type de bac est décrit par exemple dans le document FR 2 619 896 . Ces bacs doivent être disposés, sans eau dans les logements, dans une zone de congélation d'un réfrigérateur pour que le liquide eutectique soit à une température basse. Une fois que le liquide a atteint une température suffisamment basse, l'utilisateur peut remplir les logements d'eau et obtenir des glaçons. Le mode opératoire pour la formation de glaçons à partir de ces bacs est relativement contraignant.This type of tray is described for example in the document FR 2,619,896 . These tanks must be placed, without water in the housing, in a freezing zone of a refrigerator so that the eutectic liquid is at a low temperature. Once the liquid has reached a sufficiently low temperature, the user can fill the housings with water and obtain ice cubes. The procedure for the formation of ice cubes from these trays is relatively restrictive.

Par ailleurs, on connaît des bacs contenant un liquide eutectique à disposer dans une zone de réfrigération d'un réfrigérateur statique comprenant un évaporateur incorporé dans l'isolation et positionné sur au moins une des parois de ladite zone de réfrigération. Ce type de bac peut être monté amovible sur ladite paroi.Furthermore, there are known containers containing a eutectic liquid to be disposed in a refrigeration zone of a static refrigerator comprising an evaporator incorporated in the insulation and positioned on at least one of the walls of said refrigeration zone. This type of tray can be removably mounted on said wall.

Ce type de bac est décrit par exemple dans le document EP 0 851 191 .This type of tray is described for example in the document EP 0 851 191 .

Cependant, ces bacs à glaçons ont l'inconvénient de présenter un réceptacle ouvert. Un tel bac nécessite une quantité de liquide eutectique importante pour la formation de glaçons et est relativement coûteux à produire.However, these ice bins have the disadvantage of having an open receptacle. Such a tank requires a large amount of eutectic liquid for the formation of ice cubes and is relatively expensive to produce.

La température de la paroi du réfrigérateur est inférieure à 0°C pour permettre la formation de glaçons. De l'eau se condense sur les parois d'un tel réfrigérateur et préférentiellement sur la paroi comportant un évaporateur. Par conséquent, une couche isolante d'eau glacée se forme entre le bac à glaçons et la paroi du réfrigérateur et empêche la formation de glaçons dans les logements du bac.The temperature of the refrigerator wall is below 0 ° C to allow the formation of ice cubes. Water condenses on the walls of such a refrigerator and preferably on the wall comprising an evaporator. As a result, an insulating layer of ice water forms between the ice cube tray and the refrigerator wall and prevents the formation of ice cubes in the tank housing.

Par ailleurs, il n'est pas possible de placer ce bac à glaçons dans un appareil de réfrigération ventilé.In addition, it is not possible to place this ice bin in a ventilated refrigeration unit.

En outre, un tel bac à glaçons ne comporte qu'un nombre limité de logements de glaçons.In addition, such an ice bin has only a limited number of ice cubes.

La présente invention a pour but de proposer des bacs à glaçons fermés, de s'adapter à tous les types d'appareil de réfrigération, de minimiser la quantité de liquide eutectique pour former et conserver des glaçons, et de simplifier les bacs à glaçons existants.The purpose of the present invention is to provide closed ice bins, to adapt to all types of refrigeration apparatus, to minimize the amount of eutectic liquid for forming and preserving ice cubes, and to simplify existing ice bins. .

A cet effet, la présente invention vise un appareil de réfrigération comprenant un bac à glaçons, ledit bac à glaçons comprenant un compartiment à glaçons et un support disposé sur une paroi de l'appareil de réfrigération et ledit compartiment étant en relation thermique avec un évaporateur intégré dans ladite paroi, ledit compartiment comprenant une isolation thermique pourvue d'une enveloppe plastique et d'une couche d'isolant, une cavité contenant un liquide eutectique et des logements pour former des glaçons.For this purpose, the present invention is directed to a refrigeration apparatus comprising an ice cube tray, said ice cube tray comprising an ice cube compartment and a support disposed on a wall of the refrigeration apparatus and said compartment being in relation thermal device with an evaporator integrated in said wall, said compartment comprising a thermal insulation provided with a plastic envelope and an insulating layer, a cavity containing a eutectic liquid and housings for forming ice cubes.

Selon l'invention, le bac à glaçons comprend des moyens d'évacuation de l'eau en contact avec la paroi de l'appareil de réfrigération comprenant l'évaporateur et le support du bac à glaçons.According to the invention, the ice cube tray comprises means for evacuating the water in contact with the wall of the refrigeration apparatus comprising the evaporator and the support of the ice cube tray.

Ainsi, le bac à glaçons conforme à l'invention présente un compartiment fermé comprenant des logements pour former des glaçons et adapté à empêcher la formation d'une couche d'eau entre la paroi de l'appareil de réfrigération et le support. Les moyens d'évacuation de l'eau permettent de guider l'eau ruisselant sur la paroi de l'appareil de réfrigération en dehors de la zone où le compartiment est en relation thermique avec l'évaporateur.Thus, the ice tray according to the invention has a closed compartment comprising housings for forming ice cubes and adapted to prevent the formation of a layer of water between the wall of the refrigeration apparatus and the support. The means for discharging the water make it possible to guide the trickling water on the wall of the refrigeration apparatus outside the zone where the compartment is in thermal relation with the evaporator.

L'eau peut alors s'écouler le long des parois du support.The water can then flow along the walls of the support.

Selon un mode de réalisation préféré de l'invention, les moyens d'évacuation de l'eau comprennent une goulotte.According to a preferred embodiment of the invention, the means for discharging water comprise a chute.

La Demanderesse a pu constater qu'en ménageant une goulotte de manière suffisamment importante, le bac à glaçons est adapté à recueillir l'eau et à l'évacuer en dehors de la zone où le compartiment est en relation thermique avec l'évaporateur, tout en évitant la formation de givre sur le support du bac à glaçons.The Applicant has found that by sparing a chute sufficiently large, the ice cube tray is adapted to collect water and evacuate outside the zone where the compartment is in thermal relation with the evaporator, while avoiding the formation of frost on the ice cube tray support.

En pratique, le compartiment forme une boîte comprenant une paroi inférieure, une paroi supérieure, deux parois périphériques latérales et une paroi périphérique avant destinée à supporter les logements à glaçons.In practice, the compartment forms a box comprising a bottom wall, an upper wall, two side peripheral walls and a front peripheral wall for supporting the ice boxes.

Cette forme simplifiée du compartiment permet d'obtenir à moindre coût un bac à glaçons s'adaptant à des appareils de réfrigération statiques et ventilés.This simplified form of the compartment makes it possible to obtain at an inexpensive cost an ice cube tray that adapts to static and ventilated refrigeration equipment.

Grâce à ladite au moins une concavité d'écoulement de l'eau du bac à glaçons, la totalité de l'eau ruisselant vers le bac à glaçons est évacuée en direction des parois périphériques et de la paroi avant.With the at least one concavity of water flow from the ice tray, all the water flowing to the ice cube tray is discharged towards the peripheral walls and the front wall.

On évite ainsi la stagnation d'eau dans la zone où le compartiment est en relation thermique avec l'évaporateur.This prevents water stagnation in the zone where the compartment is in thermal relation with the evaporator.

Par ailleurs, la goulotte s'étend sensiblement dans un plan formant un angle compris entre 1 et 5° avec ladite paroi supérieure du support.Furthermore, the chute extends substantially in a plane forming an angle of between 1 and 5 ° with said upper wall of the support.

Grâce à cette disposition particulière de la goulotte, lorsque le compartiment est placé horizontalement, avec ces parois périphériques verticales et parois supérieures et inférieures, de manière à former une boîte avec une ouverture frontale permettant l'introduction de l'eau dans les logements, l'inclinaison de la goulotte permet de faciliter encore l'évacuation de l'eau ruisselant sur le bac à glaçons.Thanks to this particular arrangement of the chute, when the compartment is placed horizontally, with these vertical peripheral walls and upper and lower walls, so as to form a box with a front opening for the introduction of water into the housing, l Inclination of the chute further facilitates the evacuation of dripping water on the ice tray.

D'autres avantages de l'invention apparaîtront encore dans la description ci-après.Other advantages of the invention will become apparent in the description below.

Suivant le mode de réalisation du bac à glaçons, la boîte 1 comprend trois ou quatre parois périphériques.According to the embodiment of the ice cube tray, the box 1 comprises three or four peripheral walls.

Par ailleurs, le support 3 peut être ajouré dans la partie centrale pour favoriser la relation thermique entre le compartiment 2 et l'évaporateur 10 pour former des glaçons. Cette ouverture 17 dans le support 3 permet de supprimer une paroi d'isolation entre le compartiment 2 et la paroi 4 de la cuve 9.Furthermore, the support 3 may be perforated in the central portion to promote the thermal relationship between the compartment 2 and the evaporator 10 to form ice cubes. This opening 17 in the support 3 makes it possible to remove an insulating wall between the compartment 2 and the wall 4 of the tank 9.

L'ouverture 17 du support 3 peut avoir une hauteur de 180mm et une largeur de 180mm.The opening 17 of the support 3 can have a height of 180mm and a width of 180mm.

Dans ce mode de réalisation, le support 3 peut comporter une paroi périphérique uniquement sur une portion de la surface de la boîte 1 en contact avec la paroi 4 de la cuve 9.In this embodiment, the support 3 may comprise a peripheral wall only on a portion of the surface of the box 1 in contact with the wall 4 of the tank 9.

Comme bien illustré sur la figure 2, cette paroi périphérique avant 7 est destiné à recevoir des moyens de stockage d'eau dans le compartiment 2.As well illustrated on the figure 2 , this front peripheral wall 7 is intended to receive water storage means in the compartment 2.

Ces moyens de stockage d'eau dans le compartiment 2 sont constitués par exemple de logements à glaçons 8 faisant partie intégrante du compartiment 2 ou ménagés dans un plateau amovible.These water storage means in the compartment 2 consist for example of ice cubes 8 forming an integral part of the compartment 2 or formed in a removable tray.

Les logements à glaçons 8 comprennent des cavités destinées à contenir de l'eau pour la transformer en glaçons.The ice cubes 8 include cavities for containing water to turn it into ice cubes.

Le support 3 du bac à glaçons fait partie intégrante de la paroi 4a de la cuve 9 ou est fixé par des moyens connus de l'homme du métier.The support 3 of the ice cube tray is an integral part of the wall 4a of the tank 9 or is fixed by means known to those skilled in the art.

Ce support 3 peut être rendu amovible en fonction des moyens de fixation utilisés.This support 3 can be made removable depending on the fastening means used.

Selon un mode de réalisation, le support 3 peut être fixé à une paroi 4 de la cuve 9 par soudage, et de préférence par soudage à ultrasons.According to one embodiment, the support 3 can be fixed to a wall 4 of the tank 9 by welding, and preferably by ultrasonic welding.

Selon un autre mode de réalisation, le support 3 peut comporter des moyens de fixation magnétiques coopérant avec d'autres moyens de fixation magnétiques disposés sur une paroi 4 de la cuve 9.

Préférentiellement, ladite couche d'isolant 12 est en polystyrène expansé.Preferably, said insulating layer 12 is made of expanded polystyrene.

Le bac à glaçons comprend des moyens d'évacuation de l'eau 14 en contact avec la paroi 4 de l'appareil de réfrigération comprenant l'évaporateur 10 et le support 3 du bac à glaçons.The ice cube tray comprises water evacuation means 14 in contact with the wall 4 of the refrigeration apparatus comprising the evaporator 10 and the support 3 of the ice cube tray.

Les moyens d'écoulement d'eau 14 du bac à glaçons ont pour but d'empêcher l'eau de s'écouler entre le bac à glaçons et une paroi 4 de la cuve 9 notamment lors du dégivrage de l'appareil de réfrigération.The water flow means 14 of the ice cube tray are intended to prevent water from flowing between the ice cube tray and a wall 4 of the tank 9 in particular during the defrosting of the refrigeration apparatus.

L'appareil de réfrigération comprend au moins un moyen de dégivrage pour supprimer la formation de glace sur une desdites parois 4 de la cuve 9. Le dispositif de dégivrage peut être mis en fonctionnement automatiquement par des moyens de commande de l'appareil de réfrigération. Ledit au moins un moyen de chauffage est généralement réalisé par le cycle de fonctionnement du compresseur. Des moyens de récupération de l'eau, tels que une conduite, sont disposés dans le fond de l'appareil de réfrigération.The refrigerating apparatus comprises at least one defrosting means for suppressing the formation of ice on one of said walls 4 of the tank 9. The defrosting device can be operated automatically by control means of the refrigeration apparatus. Said at least one heating means is generally achieved by the operating cycle of the compressor. Water recovery means, such as a pipe, are arranged in the bottom of the refrigeration apparatus.

Le bac à glaçons, contenant un liquide eutectique et une isolation thermique, est dimensionné de manière à résister à l'élévation de température engendrée par ce dispositif de dégivrage pour conserver les glaçons.The ice bin, containing a eutectic liquid and a thermal insulation, is sized to withstand the temperature rise generated by the defrosting device to keep the ice cubes.

Les moyens d'évacuation de l'eau 14 permettent d'évacuer l'eau lors du dégivrage en dehors de la zone où le compartiment 2 est en relation thermique avec l'évaporateur 10 pour éviter la formation de glace entre ceux-ci.The water evacuation means 14 make it possible to evacuate the water during defrosting outside the zone where the compartment 2 is in thermal relation with the evaporator 10 to prevent the formation of ice between them.

Les moyens d'évacuation de l'eau 14 comprennent une goulotte 15. Une paroi supérieure du support 3 comprend la goulotte 15.The means for discharging the water 14 comprise a chute 15. An upper wall of the support 3 comprises the chute 15.

La goulotte 15 s'étend sensiblement dans un plan formant un angle compris entre 1 et 5° avec ladite paroi supérieure du support 3.The trough 15 extends substantially in a plane forming an angle of between 1 and 5 ° with said upper wall of the support 3.

Afin de permettre l'évacuation de l'eau, la goulotte 15 comprend au moins une ouverture à une extrémité.In order to allow the evacuation of water, the chute 15 comprises at least one opening at one end.

Dans ce mode de réalisation, l'ouverture est prévue dans une portion de l'une des parois périphériques latérales 20, 21.In this embodiment, the opening is provided in a portion of one of the lateral peripheral walls 20, 21.

Cette ouverture est dimensionnée de manière à pouvoir évacuer le long du bac à glaçons l'eau provenant de la paroi 4 de la cuve 9.This opening is dimensioned so as to be able to discharge the water coming from the wall 4 of the tank 9 along the ice cube tray 9.

Afin de permettre une bonne évacuation de l'eau, la portion de la paroi périphérique latérale 20, 21 comportant l'ouverture est disposée dans la partie à proximité de la paroi 4 de la cuve 9.In order to allow a good evacuation of the water, the portion of the lateral peripheral wall 20, 21 comprising the opening is disposed in the part near the wall 4 of the tank 9.

Dans un autre mode de réalisation, la goulotte 15 comprend une ouverture à chaque extrémité.In another embodiment, the chute 15 includes an opening at each end.

L'évacuation de l'eau peut également s'effectuer par débordement du niveau d'eau au-dessus du bord supérieur d'une paroi périphérique du support.The evacuation of water can also be effected by overflow of the water level above the upper edge of a peripheral wall of the support.

On notera également dans ce mode de réalisation que la boîte 1 présente dans sa partie supérieure une concavité d'écoulement de l'eau qui s'étend sensiblement dans un plan. Ainsi, les moyens d'évacuation de l'eau 14 comprennent au moins une concavité d'écoulement de l'eau 16.It will also be noted in this embodiment that the box 1 has in its upper part a water flow concavity which extends substantially in a plane. Thus, the means for discharging the water 14 comprise at least one water flow concavity 16.

Ce plan est incliné par rapport à la paroi 4 de la cuve 9 et à la paroi périphérique avant 7 du compartiment 2.This plane is inclined with respect to the wall 4 of the tank 9 and to the front peripheral wall 7 of the compartment 2.

Une paroi supérieure du support 3 comprend ladite au moins une concavité d'écoulement d'eau 16.An upper wall of the support 3 comprises said at least one water flow concavity 16.

Ladite au moins une concavité d'écoulement de l'eau 16 s'étend sensiblement de la paroi 4 de la cuve 9 jusqu'à la paroi périphérique avant 7 du compartiment 2.Said at least one flow concavity of the water 16 extends substantially from the wall 4 of the tank 9 to the front peripheral wall 7 of the compartment 2.

A titre d'exemple, le rayon de ladite au moins une concavité d'écoulement d'eau 16 peut être égal à environ 60mm.For example, the radius of said at least one water flow concavity 16 may be about 60mm.

A titre d'exemples non limitatifs, les dimensions internes de ce compartiment 2 sont telles qu'elles permettent d'obtenir un volume utile du compartiment autorisant le positionnement de 25 logements à glaçons 8.By way of nonlimiting examples, the internal dimensions of this compartment 2 are such that they make it possible to obtain a useful volume of the compartment authorizing the positioning of 25 ice cubes 8.

Le compartiment 2 comprend des rangées de logements 8 de glaçons disposées verticalement. Le nombre de rangées de logements 8 à glaçons est de 4 dans le mode de réalisation décrit.The compartment 2 comprises rows of housings 8 of ice cubes arranged vertically. The number of rows of housings 8 to ice cubes is 4 in the embodiment described.

A titre d'exemple, les parois périphériques latérales 20, 21 ont une largeur de 80mm et la paroi périphérique avant 7 a une largeur de l'ordre 200mm.By way of example, the lateral peripheral walls 20, 21 have a width of 80 mm and the front peripheral wall 7 has a width of about 200 mm.

La hauteur du compartiment 2 peut être environ égale à 200mm.The height of the compartment 2 may be about 200mm.

En outre, les coins du support 2 et du compartiment 3 présentent un rayon suffisant pour favoriser l'écoulement de l'eau le long du bac à glaçons, et par exemple un rayon supérieur à 5mm.In addition, the corners of the support 2 and the compartment 3 have a radius sufficient to promote the flow of water along the ice cube tray, and for example a radius greater than 5mm.

Ainsi, la présente invention permet de proposer un bac à glaçons adapté à tout type d'appareil de réfrigération.Thus, the present invention makes it possible to propose an ice cube tray adapted to any type of refrigeration appliance.

Lorsque les logements 8 ont été remplis d'eau, le compartiment 2 est placé dans l'appareil de réfrigération tel qu'illustré sur la figure 2 par assemblage sur le support 3.When the housings 8 have been filled with water, the compartment 2 is placed in the refrigerating appliance as illustrated in FIG. figure 2 by assembly on the support 3.

Pendant la phase fonctionnement de l'évaporateur produisant du froid, le liquide eutectique emmagasine de l'énergie et l'eau devient de la glace.During the operation phase of the evaporator producing cold, the eutectic liquid stores energy and the water becomes ice.

Lorsque l'évaporateur est arrêté, la production de froid est interrompue, un échange thermique entre le liquide eutectique et les glaçons permet de conserver les glaçons dans cet état physique.When the evaporator is stopped, the production of cold is interrupted, a heat exchange between the eutectic liquid and the ice cubes makes it possible to keep the ice cubes in this physical state.

Le compartiment 2 se détache du support 3 pour extraire des glaçons des logements 8. Les glaçons se retirent des logements 8 soit par déformation desdits logements 8 soit des plateaux amovibles. Pour enlever les glaçons du compartiment 2, les logements 8 peuvent être placés sous un jet d'eau chaud d'un robinet.The compartment 2 is detached from the support 3 to extract ice cubes from the housing 8. The ice cubes are removed from the housing 8 either by deformation of said housing 8 or removable trays. To remove the ice cubes compartment 2, the housing 8 can be placed under a stream of hot water from a tap.

Dans un mode de réalisation préféré, le compartiment 2 est fixé de manière amovible sur le support 3 et par des moyens d'encliquetage élastique 18.In a preferred embodiment, the compartment 2 is removably attached to the support 3 and by resilient latching means 18.

En pratique, l'effort d'encliquetage doit être suffisamment important pour permettre le transport de l'appareil de réfrigération.In practice, the latching force must be large enough to allow the transport of the refrigeration apparatus.

En pratique, l'effort d'encliquetage est compris entre 8 et 20N, et par exemple dans ce mode de réalisation, un effort égal à 10N.In practice, the latching force is between 8 and 20N, and for example in this embodiment, a force equal to 10N.

Afin de permettre un positionnement simple du compartiment 2 sur le support 3, les moyens d'encliquetage élastique 18 comprennent une rainure de positionnement sur une paroi périphérique opposée 20 du compartiment 2 à la paroi périphérique 21 comportant la lame ressort déformable.In order to allow simple positioning of the compartment 2 on the support 3, the resilient latching means 18 comprise a positioning groove on an opposite peripheral wall 20 of the compartment 2 to the peripheral wall 21 comprising the deformable spring blade.

Le support 3 comprend une paroi périphérique latérale adaptée à recevoir la rainure.The support 3 comprises a lateral peripheral wall adapted to receive the groove.

La rainure du compartiment 2 est engagée dans une première fente de la paroi périphérique latérale du support 3. Le compartiment 2 est déplacé en rotation jusqu'à l'encliquetage de la lame ressort déformable dans une seconde fente d'une paroi périphérique latérale opposée du support 3.The groove of the compartment 2 is engaged in a first slot of the lateral peripheral wall of the support 3. The compartment 2 is moved in rotation until the detent of the deformable spring blade snaps into a second slot of an opposite lateral peripheral wall of the support 3.

Les moyens d'encliquetage élastique 18 se fixent par un mouvement de rotation.The elastic latching means 18 are fixed by a rotational movement.
