Abstract

The cold drinks dispenser has a sealed, heat-insulated reservoir (3) containing a refrigeration fluid (5) in the liquid state, into which a serpentine flow conduit, for conveying the drinks liquid, projects. The refrigeration fluid (5) is held at a given temp. via a temp. regulation device incorporating a temp. probe (2) contained within a horizontal sleeve (1) projecting into the reservoir (3) at a point slightly below the surface of the refrigeration fluid (5). Pref. this sleeve (1) is positioned above the serpentine flow conduit (7). A second serpentine conduit (8) positioned in the vapour space (6) above the refrigeration liquid (5) is coupled in a refrigeration n circuit for condensing the vapour to maintain the correct temp. The temp. regulation is extremely precise.

Description

L'objet de l'invention concerne un dispositif améliorant la régulation de température sur les appareils refroidisseurs de boissons.The object of the invention relates to a device improving the temperature regulation on beverage coolers.

I1 est destiné à contrôler d'une manière plus précise la température du fluide frigorigène genre Fréon dans les appareils où les serpentins pour la boissons baignent directement dans un fluide frigorigène. It is intended to more precisely control the temperature of the Freon-type refrigerant in devices where the coils for the drinks are immersed directly in a refrigerant.

Dans les dispositifs connus la sonde servant à la prise de la température est disposée verticalement dans une gaine métallique centrée sur l'axe des serpentins où circule la boisson. I1 s'ensuit que la gaine de la sonde traverse des couches de fluide frigorigène à différentes températures allant de la phase gazeuse la plus chaude aux couches liquides de plus en plus froides ; De ce fait, la prise de température sera plus ou moins précise selon la longueur de la sonde et saposition dans la gaine.In known devices the probe used for taking the temperature is arranged vertically in a metal sheath centered on the axis of the coils where the drink circulates. It follows that the sheath of the probe passes through layers of refrigerant at different temperatures ranging from the hottest gas phase to the increasingly cold liquid layers; Therefore, the temperature measurement will be more or less precise depending on the length of the probe and the position in the sheath.

Le dispositif suivant l'invention supprime ces inconvénients et permet d'obtenir une prise de température très précise d'où une bonne régulation de température sans que la longueur de la sonde ait une influence.The device according to the invention eliminates these drawbacks and makes it possible to obtain a very precise temperature measurement, hence good temperature regulation without the length of the probe having an influence.

I1 est constitué par une gaine pour la sonde disposée horizontalement au-dessus et très près des serpentins pour la boisson et devant être entièrement recouverte par le fluide frigorigène en phase liquide. I1 is constituted by a sheath for the probe arranged horizontally above and very close to the coils for the drink and having to be completely covered by the refrigerant in liquid phase.

Sur le dessin annexé donné à titre d'exemple non limitatif d'une des formes de réalisation de l'objet de l'invention la figure représente vue en coupe longitudinale un échangeur de températurfe équipé du dispositif améliorant la régulation.In the accompanying drawing given by way of nonlimiting example of one of the embodiments of the object of the invention, the figure shows a longitudinal section view of a temperature exchanger equipped with the device improving regulation.

Le dispositif est constitué par la gaine 1 dans laquelle se trouve la sonde 2 pour la prise de température. La gaine 1 est disposée horizontalement dans le réservoir 3 étanche et isolé 4 rempli après avoir fait le vide de fluide frigorigène en phase liquide 5 dont le niveau est légèrement supérieur à la gaine 1. Au dessus de la phase liquide 5 se trouve la phase gazeuse 6. The device consists of the sheath 1 in which the probe 2 is located for taking the temperature. The sheath 1 is disposed horizontally in the sealed and insulated tank 3 filled after having evacuated the refrigerant in the liquid phase 5, the level of which is slightly higher than the sheath 1. Above the liquid phase 5 is the gas phase 6.

Dans la phase liquide 5 se trouve immergé le serpentin 7 dans lequel circule la boisson à réfrigérer.In the liquid phase 5 is immersed the coil 7 in which the drink to be refrigerated circulates.

Dans la phase gazeuse 6 se trouve le serpentin 8 refroidi par un groupe frigorifique dont la mise en marche et 1' arrêt sont commandés par la sonde 2.In the gas phase 6 there is the coil 8 cooled by a refrigeration unit, the starting and stopping of which are controlled by the probe 2.

Lorsque le groupe frigorifique fonctionne , le serpentin 8 condense les vapeurs 6 ce qui fait baisser la pression dans le réservoir 3 et abaisse le point d'ébullition du liquide 5 d'où sa température. La boisson chaude contenue dans le serpentin 7 fait bouillir le liquide 5 ce qui la refroidi.When the refrigeration unit is operating, the coil 8 condenses the vapors 6 which lowers the pressure in the tank 3 and lowers the boiling point of the liquid 5, hence its temperature. The hot drink contained in the coil 7 boils the liquid 5 which cools it.

La sonde 2 contenue dans la gaine 1 se trouve à proximité immédiate du serpentin 7 elle va réagir immédiatement dès qu'une boisson chaude va circuler dans le serpentin 7 et mettre en route le groupe frigorifique.The probe 2 contained in the sheath 1 is in the immediate vicinity of the coil 7 it will react immediately as soon as a hot drink circulates in the coil 7 and start the refrigeration unit.

La sonde 2 étant entièrement dans la couche supérieure la plus chaude du liquide frigorigène 5, elle arrêtera le groupe frigorifique dès que la température de consigne sera atteinte sans descendre en dessous et avec une bonne précision quelle que soit la longueur de la sonde. The probe 2 being entirely in the hottest upper layer of the refrigerant 5, it will stop the refrigeration unit as soon as the set temperature is reached without falling below and with good precision whatever the length of the probe.
