Description

DOMAINE DE L'INVENTIONFIELD OF THE INVENTION

La présente invention concerne les systèmes de balnéothérapie comportant une baignoire et une pompe de circulation qui propulse de l'eau en circuit fermé.The present invention relates to balneotherapy systems comprising a bath and a circulation pump that propels water in a closed circuit.

ETAT DE LA TECHNIQUESTATE OF THE ART

On connait des systèmes de balnéothérapie 1, qui sont des bains bouillonnants remplis d'eau chaude, comportant une baignoire 2 une pompe de circulation 3 qui propulse de l'eau en circuit fermé à travers un circuit de circulation passant par la baignoire.There are known balneotherapy systems 1, which are bubbling baths filled with hot water, having a bath 2 a circulation pump 3 which propels water in a closed circuit through a circulation circuit passing through the bath.

La pompe de circulation 3 propulse un liquide, typiquement de l'eau, qui peut être mélangé avec de l'air par effet venturi en sortie de la buse d'injection 5. La pompe 3 propulse donc un liquide dans un tuyau d'alimentation 6 raccordé à la buse injection 5 puis alimentant une série de buses d'injection 5 disposées sur les parois de la baignoire 2. L'eau s'écoule ensuite par un orifice de circulation ménagé dans une paroi de la baignoire 2, généralement équipé d'une crépine 8, vers un tuyau rigide d'aspiration 4, d'où elle est pompée par la pompe de circulation 3 pour être réinjectée dans le tuyau d'alimentation 6.The circulation pump 3 propels a liquid, typically water, which can be mixed with air by the venturi effect at the outlet of the injection nozzle 5. The pump 3 thus propels a liquid in a supply pipe 6 connected to the injection nozzle 5 and feeding a series of injection nozzles 5 disposed on the walls of the bath 2. The water then flows through a circulating orifice formed in a wall of the bath 2, generally equipped with a strainer 8, to a rigid suction pipe 4, from where it is pumped by the circulation pump 3 to be reinjected into the feed pipe 6.

Les buses d'injection 5 étant connectées en série au tuyau d'alimentation 6, la pression au niveau de chaque buse d'injection 5 est d'autant plus faible que la buse d'injection 5 est éloignée de la pompe de circulation 3.As the injection nozzles 5 are connected in series with the supply pipe 6, the pressure at each injection nozzle 5 is lower as the injection nozzle 5 is moved away from the circulation pump 3.

Un tel système de balnéothérapie 1 comporte de nombreux inconvénients. L'homogénéité de la puissance des jets issus des buses d'injection 5 est difficile à régler. En outre, la puissance de la pompe doit être importante pour fournir une puissance de jet suffisante au niveau des buses d'injection 5 les plus éloignées de la pompe.Such a balneotherapy system 1 has many disadvantages. The homogeneity of the power of the jets from the injection nozzles 5 is difficult to adjust. In addition, the power of the pump must be important to provide sufficient jet power at the injection nozzles 5 furthest from the pump.

De plus, la norme NF EN60335-2-60 impose une limite de rétention d'eau après vidange de la baignoire à la fin du massage. La quantité d'eau restant dans la tuyauterie de la baignoire doit être inférieure à un ratio de 2L de rétention d'eau pour 1000L de contenance.
Les buses d'injection 5 sont donc développés de façon à facilité l'écoulement naturel de l'eau après vidange de la baignoire.In addition, the NF EN60335-2-60 standard imposes a limit of water retention after emptying the bath at the end of the massage. The amount of water remaining in the bathtub piping must be less than a ratio of 2L of water retention per 1000L of capacity.
The injection nozzles 5 are therefore developed so as to facilitate the natural flow of water after emptying the bath.

Il existe des buses d'injection 5.1 qui sont utilisés dans le monde du SPA. Les buses d'injection 5.1 sont beaucoup plus efficaces au niveau puissance de jet car de par leur construction technique, elles sont adaptées pour une meilleure circulation du liquide afin de permettre une puissance maximum. Par contre, les buses d'injection 5.1, ne sont pas adaptées pour fonctionner avec un système de circulation d'eau qui facilite l'écoulement de l'eau par rapport à la norme NF EN60335-2-60.
Ce qui ne pose aucun problème à un constructeur de SPA, car ses produits sont prévus obligatoirement toujours remplis d'eau. De plus au niveau d'un SPA, pour maintenir l'eau toujours propre, il faut passer par un système de filtration, comme une piscine.There are 5.1 injection nozzles that are used in the world of the SPA. 5.1 injection nozzles are much more efficient jet power because of their technical construction, they are adapted for better circulation of the liquid to allow maximum power. On the other hand, the injection nozzles 5.1, are not adapted to operate with a water circulation system which facilitates the flow of water compared to the NF EN60335-2-60 standard.
This poses no problem to a manufacturer of SPA, because its products are always obligatorily filled with water. In addition to a SPA, to keep the water always clean, it must go through a filtration system, like a pool.

Afin de profiter de la puissance d'une buse d'injection 5.1, il a été proposé d'intégrer des buses d'injection 5.1 dans une baignoire 2. Cela implique obligatoirement des modifications et des contraintes majeures et notamment le raccordement des buses d'injection 5.1 en parallèle (comme illustré sur la figure 2) a et non en série comme les buses d'injection 5 (comme illustré sur la figure 1).
Ces modifications posent un problème important de rétention d'eau dans les tuyaux d'alimentation 6 et dans le tuyau rigide de refoulement 4.1 (voir figure 2).
Ces modifications imposent la modification de la conception de la pompe de circulation 3 afin de permettre un raccordement aisé du tuyau rigide de refoulement 4.1 et l'intégration d'un collecteur de distribution d'eau 4.2 en partie basse sous la baignoire 2.In order to take advantage of the power of a 5.1 injection nozzle, it has been proposed to integrate 5.1 injection nozzles into a bathtub 2. This necessarily implies major modifications and constraints, and in particular the connection of the nozzles. 5.1 injection in parallel (as shown in figure 2 ) and not in series as the injection nozzles 5 (as shown in FIG. figure 1 ).
These modifications pose a significant problem of water retention in the supply pipes 6 and in the rigid discharge pipe 4.1 (see FIG. figure 2 ).
These modifications require the modification of the design of the circulation pump 3 to allow easy connection of the rigid discharge pipe 4.1 and the integration of a 4.2 water distribution manifold at the bottom under the bath 2.

Le collecteur 4.2 se trouve alors en dessous de la pompe de circulation 3 et il est par conséquent impossible de vidanger le collecteur 4.2 avec la pompe de circulation 3. Ceci est un problème dans les installations de balnéothérapie, pour lesquelles les normes en vigueur imposeraient de vidanger le collecteur 4.2 après chaque utilisation pour éviter la stagnation de l'eau.The collector 4.2 is then below the circulation pump 3 and it is therefore impossible to drain the collector 4.2 with the circulation pump 3. This is a problem in balneotherapy installations, for which the standards in force would require drain the manifold 4.2 after each use to avoid stagnation of the water.

Le document EP-A2-0811366 divulgue toutes les caractéristiques techniques du préambule de la revendication 1.The document EP-A2-0811366 discloses all the technical features of the preamble of claim 1.
