Abstract

The portable refrigerator uses an electrically (3) powered Peltier effect thermo element (2) to provide cool air or heating, as required, and has the internal space divided into two compartments by a partition (9) which is offset towards one end of the unit, making one compartment larger than the other. The cover (1), which has the battery, thermo element and circulation fan (15) mounted at one end, is constructed to be thicker in the region of these fittings and thinner across the unoccupied half of its width (12). With the lid fitted so its thin part is over the partition (9) the lid clearance over the partition allows cool air to circulate in the entire volume. If however the lid is reversed, the thicker part rests on the partition and isolates the smaller part of the volume if it is to be heated, while the other part acts as an insulated cool chamber.

Description

Dispositif de réfrigérateur transportable avec thermoélément et production de frigories ou de calories par alternance. Transportable refrigerator device with thermoelement and alternating production of frigories or calories.

Il est destiné à permettre une inter-communication des compartiments lors de l'émission du froid et la séparation des mêmes capacités lors de l'échauffement de l'une.  It is intended to allow an inter-communication of the compartments during the emission of cold and the separation of the same capacities during the heating of one.

Jusqu'à ce jour les appareils de ce genre utilisant un thermo-élément du type dit "Lepelletier" à inversion de marche dont le changement de position place le générateur sur l'un des compartiments de la capacité fonctionnelle, ne permettait la réfrigération ou l'échauffement que d'un seul secteur. L'usager perdait donc une puissance lors de la réfrigération d'une denrée dans le compratiment réfrigérateur. To date, devices of this type using a thermo-element of the so-called "Lepelletier" type with reverse operation, the change of position of which places the generator on one of the compartments of functional capacity, did not allow refrigeration or heating only one sector. The user therefore lost power when refrigerating a food in the refrigerator compartment.

Le dispositif suivant l'invention supprime cet inconvénient et permet de répandre les frigories dans la double compartimentation et d'isoler ensuite celle utilisée pour le chauffement. The device according to the invention eliminates this drawback and makes it possible to spread the frigories in the double compartmentalisation and then to isolate the one used for heating.

I1 se caractérise par la forme fonctionnelle du parement interne du couvercle comportant un épaulement qui par son inversion de position obture les deux chambres uniquement lors de l'émission thermique et permet leur inter-communication lors de l'é;:iission de frigories. I1 is characterized by the functional form of the internal facing of the cover comprising a shoulder which, by its position reversal, closes the two chambers only during thermal emission and allows their inter-communication during e;: iission of frigories.

Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente vu en élévation et en coupe longitudinale le dispositif dans son ensemble en position d'intercommunication.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows in elevation and in longitudinal section the device as a whole in the intercommunication position.

La figure 2 montre le même objet en position d'isolation de la chambre d'échauffement. Figure 2 shows the same object in the isolation position of the heating chamber.

La figure 3 est une vue en perspective de la configuration générale de l'appareil. Figure 3 is a perspective view of the general configuration of the device.

La capacité thermique à parois isolantes et constituée figures 1 et 2 par un couvercle mobile 1 dans lequel sont intégrés, le thermo-élément 2 et l'ensemble des circuits avec pile ou accumulateur 3. Son parement interne comporte un épaulement 4 à large surface de contact jointif.  The thermal capacity with insulating walls and constituted in FIGS. 1 and 2 by a movable cover 1 into which the thermo-element 2 and all the circuits with battery or accumulator 3 are integrated. Its internal facing has a shoulder 4 with a large surface area of contact joined.

Sa périphérie 5 est pourvue de profils d'emboîtement. Its periphery 5 is provided with interlocking profiles.

La capacité 6 est divisée en deux secteurs 7, 8 par un cloisonnement 9 à large surface de contact formée par son arête 10. The capacity 6 is divided into two sectors 7, 8 by a partition 9 with a large contact surface formed by its edge 10.

Lors de 1 ' émission de frigories figure 1, le couvercle à son secteur 11 placé sur la chambre 7 et l ' épaulement 4 ne contacte pas le cloisonnement 9. During the emission of frigories in FIG. 1, the cover with its sector 11 placed on the chamber 7 and the shoulder 4 does not contact the partitioning 9.

L'espace 13 permet le passage des frigories dans la capacité 8 flèche A. Space 13 allows the passage of frigories in capacity 8 arrow A.

Par contre, lorsque le secteur 11 est placé sur la chambre 8, Fig 2, l'espace 13 est obturé par la barrière classique 14 formée par le contact de l'espacement 4 avec la surface 10 du cloisonnement 9. On the other hand, when the sector 11 is placed on the chamber 8, FIG. 2, the space 13 is closed by the conventional barrier 14 formed by the contact of the spacing 4 with the surface 10 of the partition 9.

L ' échauffement n' est plus communiqué au secteur 7 ou les denrées continuent à être maintenues à une basse température. The heating is no longer communicated to sector 7 or the food continues to be kept at a low temperature.

Un moteur avec ventilateur à double hélice 15 est placé près du thermo-élément pour ventiler et éliminer les calories. Un carter avec ouïes d ' aération le protège. A motor with a double propeller fan 15 is placed near the thermo-element to ventilate and eliminate calories. A housing with ventilation openings protects it.

On utilise donc sans perte l'émission de frigories. The emission of frigories is therefore used without loss.

Il peut en être de même pour l'émission de calories car il suffit d'inverser la polarisation du thermo-élément 2 pour obtenir un résultat identique c ' est-à-dire l'inter-communication du chauffage et l'isolation du refroidissement.It can be the same for the emission of calories because it suffices to reverse the polarization of the thermo-element 2 to obtain an identical result, that is to say the inter-communication of the heating and the insulation of the cooling. .

I1 est enfin possible de placer sous le thermo-élément un bac à glaçons 15. It is finally possible to place an ice cube tray 15 under the thermo-element.

Ce dernier sera préférentiellement constitué par un "Caloduc", c'est-à-dire une capacité avec vide et remplie de "fréon". L'eau étant contenue dans une poche plastique pour éviter son renversement en cours de transport. The latter will preferably consist of a "Heat pipe", that is to say a capacity with vacuum and filled with "Freon". The water is contained in a plastic bag to prevent spillage during transport.

Toutefois les formes, dimensions et dispositions des différents éléments pourront varier dans la limite des équivalents comme d'ailleurs les matières utilisées pour leur fabrication, sans changer pour cela la conception générale de l'invention qui vient d 'être décrite.  However, the shapes, dimensions and arrangements of the various elements may vary within the limit of equivalents, as indeed the materials used for their manufacture, without thereby changing the general conception of the invention which has just been described.
