Abstract

The water enters the tank 1 via a pressure reducing valve 5 which lowers and regulates the pressure and via a valve 6 which enables the passage cross-section of the water to be adjusted; the drawing-off cock, consisting for example of an electromagnetic valve 7, is placed so as to be dependent on a timer 8; an electromagnetic valve 9 situated upstream of the pressure reducing valve is placed so as to be dependent on the timer 8.

Description

La présente invention est relative à un refroidisseur d'eau du genre de ceux utilisés,notamment,dans la boulangerie. The present invention relates to a water cooler of the kind used in particular in baking.

De tels refroidisseurs sont généralement constitués par une cuve, comportant intérieurement un serpentin de refroidissement et dans laquelle l'eau entre par le haut et sort par le bas. Des robinets d'arrêts sont placés à l'entrée et à la sortie de la cuve qui est pourvue, en outre, d'un robinet à flotteur. Un tube gradué à niveau d'eau permet de mesurer le volume dseau soutiré. Such coolers are generally constituted by a tank, internally comprising a cooling coil and into which the water enters from the top and exits from the bottom. Stop valves are placed at the inlet and outlet of the tank which is further provided with a float valve. A graduated tube at water level allows the volume of water withdrawn to be measured.

Naturellement, pour soutirer de l'eau il faut fermer au préalable le robinet d'entrée puis ouvrir celui de sortie. Naturally, to draw water you must close the inlet tap beforehand and then open the outlet tap.

Dans certains modes de realisations, le robinet de sortie est couplé à un compteur volumétrique ce qui permet de supprimer le tube à niveau d'eau mais de tels dispositifs sont tres coûteux. In some embodiments, the outlet valve is coupled to a volumetric meter which eliminates the water level tube but such devices are very expensive.

De plus, un tel refroidisseur doit être placé au-dessus du pétrin.Dans les fournils où cette disposition n'est pas possible, il faut utiliser une pompe qui refoule l'eau vers le pétrin avec tous les inconvénients que cela présente. In addition, such a cooler must be placed above the kneader. In bakehouses where this arrangement is not possible, a pump must be used which delivers water to the kneader with all the disadvantages that this presents.

On connait aussi des refroidisseurs dit "sous pression" dans lesquels l'eau refroidie sort sous l'effet de la pression de l'eau qui y entre. Mais de telles cuves sont onéreuses car elles doivent résister à la pression qui, en France, est de l'ordre de trois Bars. Also known as "pressure" coolers in which the cooled water leaves under the effect of the pressure of the water entering it. But such tanks are expensive because they have to withstand the pressure which, in France, is of the order of three Bars.

Naturellement, le coût de telles cuves se trouve aussi augmenté par la nécessité d'utiliser un robinet de soutirage couplé à un compteur volumétrique. Naturally, the cost of such tanks is also increased by the need to use a withdrawal valve coupled to a volumetric meter.

La présente invention, qui remédie à ces inconvénients, consiste à introduire l'eau dans la cuve sous une pression relativement basse et prédéterminée et par l'entremise d'un orifice calibré, l'eau refroidie sortant de la cuve poussée par la pression de celle qui entre. The present invention, which overcomes these drawbacks, consists in introducing the water into the tank under a relatively low and predetermined pressure and through a calibrated orifice, the cooled water leaving the tank pushed by the pressure of the one who enters.

De cette façon, en ouvrant le robinet de soutirage pendant un temps déterminé on est certain du volume d'eau refroidie qui sort de la cuve. In this way, by opening the draw-off tap for a determined time, one is certain of the volume of cooled water which leaves the tank.

Selon un mode de réalisation, le robinet de sortie est constitué par une vanne électromagnétique placée sous la dépendance d'une minuterie. Dans ce cas, en l'absence de soutirage la cuve est sous pression.  According to one embodiment, the outlet valve is constituted by an electromagnetic valve placed under the dependence of a timer. In this case, in the absence of racking, the tank is under pressure.

Selon un autre mode de réalisation, la minuterie commande aussi l'ouverture et la fermeture d'une vanne électromagnétique interposée sur la canalisation d'amenée d'eau.De cette façon,la cuve n'est en pression que durant le soutirage et peut, de ce fait, supporter une pression plus élevée. According to another embodiment, the timer also controls the opening and closing of an electromagnetic valve interposed on the water supply pipe. In this way, the tank is under pressure only during withdrawal and can , therefore, withstand higher pressure.

L'invention sera mieux comprise par la description qui va suivre, faite en se référant au dessin annexé à titre d'exemple indicatif seulement sur lequel la figure unique schématise un refroidisseur conforme à l'invention. The invention will be better understood from the description which follows, made with reference to the attached drawing by way of indicative example only, in which the single figure shows diagrammatically a cooler according to the invention.

En se reportant au dessin, on voit que 1 est une cuve étanche de construction légère telle que celle déja utilisée pour les refroidisseurs à soutirage par gravité. Referring to the drawing, it can be seen that 1 is a sealed vessel of light construction such as that already used for gravity draw coolers.

La cuve comporte à sa partie supérieure une canalisation 2 d'arrivée à'eau à refroidir et, à sa partie inférieure, une canalisation 3 de sortie de l'eau refroidie. The tank has at its upper part a pipe 2 for arriving at the water to be cooled and, at its lower part, a pipe 3 for leaving the cooled water.

De la façon connue, un serpentin évaporateur 4 d'un appareil réfrigérateur ( non représenté) est disposé dans la cuve 1,
Sur la canalisation 2 est interposé un détendeur 5 qui permet d'abaisser la pression de l'eau à une valeur comprise, par exemple, entre 0,5 et 1 Bar.
In known manner, an evaporator coil 4 of a refrigerator appliance (not shown) is placed in the tank 1,
On the pipe 2 is interposed a regulator 5 which makes it possible to lower the water pressure to a value of, for example, between 0.5 and 1 Bar.

En aval du dé tendeur est interposée une vanne 6 à section variable permettant de fixer la valeur de la section offerte au passage de l'eau donc de fixer le débit de l'eau qui entre dans le cuve et, par suite, celui de lgeau qui en sort. Downstream of the regulator is interposed a valve 6 with variable section making it possible to fix the value of the section offered to the passage of water therefore to fix the flow of water which enters the tank and, consequently, that of water coming out.

Selon un mode de réalisation, sur la canalisation de sortie est interposée une vanne électromagnétique 7 placee sous la dépendance d'une minuterie 8. According to one embodiment, an electromagnetic valve 7 placed on the outlet pipe is placed under the control of a timer 8.

Le débit de l'eau qui entre étant fixé et connu, le réglage de la minuterie permet de fixer exactement le volume à soutirer. The flow of water which enters being fixed and known, the setting of the timer makes it possible to fix exactly the volume to be drawn off.

Selon un second mode de réalisation, une vanne électromagnétique 9 est interposée sur la canalisation 2 et est placée sous la dépendance de la minuterie 8 qui ouvre et ferme les deux vannes 7 et 9 simultanément. De cette façon, la cuve 1 n'est sous pression que pendant le temps nécessaire au soutirage de l'eau refroidie,c'est-à-dire pendant des intervalles de temps très courts.  According to a second embodiment, an electromagnetic valve 9 is interposed on the pipe 2 and is placed under the dependence of the timer 8 which opens and closes the two valves 7 and 9 simultaneously. In this way, the tank 1 is only pressurized for the time necessary for drawing off the cooled water, that is to say for very short time intervals.

Bien entendu, la présente invention ne se limite pas aux modes de réalisation-décrits et représentés mais s'étend, au contraire, à toutes variantes de formes et dimensions. Of course, the present invention is not limited to the embodiments-described and shown, but extends, on the contrary, to all variants of shapes and dimensions.

C'est ainsi, entre autres,que des chicanes 10 peuvent être prévues dans la cuve pour éviter que l'eau qui entre ne modifie la température de celle qui sort.  Thus, among other things, baffles 10 can be provided in the tank to prevent the incoming water from modifying the temperature of the outgoing one.
