Description

Dispositif de chauffage et de maintien en température pour conteneur.Heating and temperature maintaining device for container.

La présente invention concerne un dispositif de chauffage et de maintien en température pour conteneur. The present invention relates to a heating and temperature maintenance device for a container.

On sait que dans la restauration collective les plats chauds doivent être maintenus au-dessus de 650C. Le dispositif selon l'invention permettant de maintenir une telle température pendant plusieurs heures est caractérisé en ce qu'il comporte un bac en inox contenant de la paraffine fixé sur le fond du conteneur, ladite paraffine fondant autour de 700 C, une plaque de chauffage électrique plaquée sur le fond du bac par un système à ressort assurant la dilatation différentielle inox/plaque de chauffage, le transfert thermique entre plaque et bac étant assuré par une pâte silicone. We know that in collective catering hot dishes must be kept above 650C. The device according to the invention making it possible to maintain such a temperature for several hours is characterized in that it comprises a stainless steel tank containing paraffin fixed on the bottom of the container, said paraffin melting around 700 ° C., a heating plate electric plated on the bottom of the tank by a spring system ensuring the differential expansion stainless steel / heating plate, the thermal transfer between plate and tank being ensured by a silicone paste.

L'invention va maintenant être décrite plus en détail en se référant à un mode de réalisation particulier cité à titre d'exemple et représenté par des dessins annexés. The invention will now be described in more detail with reference to a particular embodiment cited by way of example and shown in the accompanying drawings.

La figure 1 représente en coupe le dispositif de chauffage et de maintien en température selon l'invention. Figure 1 shows in section the heating and temperature maintenance device according to the invention.

La figure 2 représente un schéma électrique de ce dispositif. Figure 2 shows an electrical diagram of this device.

La figure 3 représente les courbes de montées en température de la paraffine. FIG. 3 represents the temperature rise curves of the paraffin.

Le dispositif selon l'invention comporte un bac en inox 1 rempli de paraffine 2. Ce bac 1 comprend un couvercle 3 relié par un joint 4 au fond 5 du conteneur (non représenté). The device according to the invention comprises a stainless steel tank 1 filled with paraffin 2. This tank 1 comprises a cover 3 connected by a seal 4 to the bottom 5 of the container (not shown).

Le fond 6 du bac 1 est muni de goujons soudés 7 entourés de ressorts 8 qui viennent appliquer une plaque de chauffage 9 sur la totalité du fond 6 du bac 1. The bottom 6 of the tray 1 is provided with welded studs 7 surrounded by springs 8 which apply a heating plate 9 to the entire bottom 6 of the tray 1.

Cette plaque 9 comporte de l'aluminium et les ressorts 8 assurent la dilatation différentielle inox/aluminium. Entre la plaque 9 et le fond 6 on a mis une pâte silicone 10 pour améliorer le transfert thermique. This plate 9 includes aluminum and the springs 8 ensure the differential expansion of stainless steel / aluminum. Between the plate 9 and the bottom 6 we put a silicone paste 10 to improve the heat transfer.

Un carter 11 vient obturer l'ouverture 12 faite dans le fond 5 du conteneur. Ce carter 11 est muni d'un joint 13 s'appliquant sur le pourtour extérieur de l'ouverture 12.  A casing 11 seals the opening 12 made in the bottom 5 of the container. This casing 11 is provided with a seal 13 applying on the outer periphery of the opening 12.

Le carter 11 et le couvercle 3 sont solidarisés par des entretoises 14 et viennent ainsi emprisonner le pourtour de l'ouverture 12. The casing 11 and the cover 3 are secured by spacers 14 and thus trap the periphery of the opening 12.

L'espace restant vide entre carter 11 et bac 1 est rempli d'isolant 15. The remaining empty space between casing 11 and tank 1 is filled with insulation 15.

La plaque 9 est alimentée en courant électrique par un cordon 16 traversant le couvercle 3 par un presse-étoupe 17. The plate 9 is supplied with electric current by a cord 16 passing through the cover 3 by a cable gland 17.

En contact avec le bac 1 on a disposé un thermostat 18 qui lorsque la température dépasse 800C environ allume un voyant lumineux 19. In contact with the tank 1, there is a thermostat 18 which, when the temperature exceeds about 800C, lights up an indicator light 19.

D'autre part, un second thermostat 20 en contact avec le bac 1 coupe l'alimentation 22 de la plaque 9 lorsque la température dépasse 1100C et ne la remet que lorsque celle-ci tombe en-dessous de 1000C. On the other hand, a second thermostat 20 in contact with the tank 1 cuts the power supply 22 to the plate 9 when the temperature exceeds 1100C and does not reset it until it drops below 1000C.

Un interrupteur 23 sert à couper et à remettre l'alimentation 22 et un voyant 24 est prévu pour signaler que l'alimentation du conteneur est mise. A switch 23 is used to cut off and put back the power supply 22 and an indicator light 24 is provided to indicate that the power supply of the container is switched on.

Le fonctionnement du dispositif selon l'invention est le suivant (voir figure 3). The operation of the device according to the invention is as follows (see Figure 3).

Lorsque l'interrupteur 23 est fermé, la plaque 9 est alimentée et la paraffine commence à chauffer et à fondre lentement (partie
A). La température de la paraffine atteint 700C et la paraffine fond complètement sans augmenter notablement de température (palier
B). Ensuite la paraffine qui est à l'état liquide augmente de température (partie C).When the switch 23 is closed, the plate 9 is energized and the paraffin begins to heat and slowly melt (part
AT). The paraffin temperature reaches 700C and the paraffin melts completely without significantly increasing the temperature (level
B). Then the paraffin which is in the liquid state increases in temperature (part C).

Lorsque celle-ci atteint 800C le voyant 19 s'allume avertissant l'utilisateur que le conteneur est prêt. Il peut donc y enfourner les plats après avoir coupé l'alimentation avec l'interrupteur 23. When it reaches 800C the indicator 19 lights up warning the user that the container is ready. He can therefore put the dishes in the oven after switching off the power with the switch 23.

Lorsque l'alimentation est coupée la température de la paraffine diminue (partie D) puis se solidifie en restant à une température voisine de 700C (palier E) avant de décroître en dessous pour se refroidir complètement. Le maintien en température au-dessus de 650C a donc lieu pendant la partie D et le palier E. When the power is cut the temperature of the paraffin decreases (part D) then solidifies while remaining at a temperature close to 700C (level E) before decreasing below to cool completely. Maintaining the temperature above 650C therefore takes place during part D and level E.

Au cas où l'utilisateur omettrait d'interrompre l'alimen tation, la température de la paraffine continue à augmenter et le thermostat 20 va commander une coupure de courant dès que la température atteindra 1100C et ce courant sera remis lorsque cette température sera redescendue à 1000C. In the event that the user fails to interrupt the supply, the temperature of the paraffin continues to increase and the thermostat 20 will command a power cut as soon as the temperature reaches 1100C and this current will be restored when this temperature has dropped to 1000C.

La température de la paraffine est ainsi stabilisée à 100-1100C. (courbe F en pointillé) ce qui évite tout accident.  The paraffin temperature is thus stabilized at 100-1100C. (curve F in dotted lines) which prevents any accident.
