Description

On connaissait jusqu'à présent les inconvénients liés à l'utilisation d'eau chaude issue d'un robinet sans que s'écoule un certain volume d'eau froide contenu dans les canalisations lorsque le dispositif comporte un mitigeur unique doté d'une arrivée d'eau chaude issue d'un ballon placé à une certaine distance. En effet, les canalisations d'eau représentent un certain volume d'eau qui se refroidit pendant l'inutilisation. En outre, le volume d'eau refroidi est comptabilisé sur les charges de l'habitation. Until now, the drawbacks associated with the use of hot water from a faucet have not been known without the flow of a certain amount of cold water contained in the pipes when the device comprises a single mixer with an inlet hot water from a balloon placed at a distance. In fact, the water pipes represent a certain volume of water that cools during the time of non-use. In addition, the volume of chilled water is counted on the loads of the house.

La présente invention a pour objet d'obvier à ces inconvénients en recyclant 10 cet eau initialement chaude et devenue froide avec une eau chaude issue du ballon lui-même thermostaté. The object of the present invention is to obviate these disadvantages by recycling this initially hot and cold water with a hot water coming from the thermostated flask itself.

Cette invention est caractérisée par une installation comportant un mitigeur (1) dont le conduit est doté d'une cellule tactile (15) commandé au moyen d'une 15 armoire électronique (16). This invention is characterized by an installation comprising a mixer (1) whose duct is provided with a touch cell (15) controlled by means of an electronic cabinet (16).

Le bouton commande le circuit de vanne (3) d'arrivée d'eau et d'eau froide. Il est pourvu d'un capteur de pression et de température permettant de programmer l'arrivée d'eau en fonction de la demande de l'opérateur. Le pilotage de l'ensemble est assuré au moyen d'un courant électrique basse tension issue d'un transformateur (14) qui alimente également une pompe de redistribution du mélange d'eau chaude et d'eau froide. The button controls the valve circuit (3) for water and cold water supply. It is equipped with a pressure and temperature sensor to program the water supply according to the demand of the operator. The control of the assembly is ensured by means of a low voltage electric current from a transformer (14) which also feeds a redistribution pump of the mixture of hot water and cold water.

25 Le dispositif peut être réalisé pour une installation unique isolée qui peut être démontée, ou adaptée à un ensemble d'habitations collectives. The device can be made for a single, isolated installation that can be dismantled or adapted to a set of collective dwellings.

L'invention ainsi définie sera mieux comprise grâce aux dessins annexés qui ne sont présentés qu'à titre d'exemple. 20 30 La figure 1 de la planche 1/2 représente le dispositif unitaire destiné à une installation individuelle. La figure 2 de la planche 2/2 représente le dispositif destiné à une installation 5 collective. En se reportant à la figure 1 de la planche 1/2, on a représenté de façon schématique, le dispositif adapté à une installation individuelle. L'ensemble du dispositif peut être monté et démonté et remplacer une installation classique. Le mitigeur thermostaté (1) utilisé pour l'écoulement de l'eau est commandé par l'électronique de l'armoire de programmation (16) et le boîtier de commande (17). The invention thus defined will be better understood thanks to the accompanying drawings which are presented by way of example. Figure 1 of Plate 1/2 shows the unitary device for individual installation. Figure 2 of the board 2/2 shows the device for a collective installation. Referring to Figure 1 of the board 1/2, there is shown schematically, the device adapted to an individual installation. The entire device can be mounted and disassembled and replace a conventional installation. The thermostatic mixer (1) used for the water flow is controlled by the electronics of the programming cabinet (16) and the control box (17).

15 La programmation électronique (16) reçoit les informations de la cellule tactile (15) et commande le coffret de commande (17) qui reçoit les informations issues des capteurs de température (3) et de pression (19) de l'eau contenue dans le mélangeur (4). The electronic programming (16) receives the information from the touch cell (15) and controls the control box (17) which receives the information from the temperature (3) and pressure (19) sensors of the water contained in the the mixer (4).

20 Le capteur de température (3) agit sur l'ouverture et la fermeture de l'arrivée d'eau du réservoir (7) relié au mélangeur (4) au moyen d'une vanne (2) connectée au boîtier marche arrêt du coffret de commande (17). The temperature sensor (3) acts on the opening and closing of the water inlet of the tank (7) connected to the mixer (4) by means of a valve (2) connected to the casing of the casing control (17).

La réserve d'eau froide contenue dans le réservoir (7) est pulsée dans le 25 mélangeur (4) au moyen d'une pompe (8) connectée à un transformateur (14) lui-même relié au boîtier de commande (17) piloté par l'armoire (16) contenant l'électronique de programmation. The cold water reserve contained in the tank (7) is pulsed in the mixer (4) by means of a pump (8) connected to a transformer (14) itself connected to the piloted control unit (17). by the cabinet (16) containing the programming electronics.

Le réservoir (7) est pourvu de dispositif anti retour au moyen de clapets (22), 30 l'un séparant le fond du réservoir (7) de la pompe (8) l'autre séparant le réservoir du 10 mélangeur (4). Ce dernier est malaxé au moyen d'un agitateur constitué par un axe tournant (21). The reservoir (7) is provided with an anti-return device by means of valves (22), one separating the bottom of the reservoir (7) from the pump (8) and the other separating the reservoir from the mixer (4). The latter is kneaded by means of an agitator constituted by a rotating shaft (21).

Ainsi décrit, le fonctionnement de l'ensemble se résume ainsi lorsque la cellule tactile détecte le réchauffement de l'eau provenant de l'alimentation d'eau chaude (10) l'arrivée d'eau froide est injectée au niveau du mélangeur (4). Lorsque l'utilisateur cesse sa consommation d'eau, l'excès d'eau chaude est stocké dans le mélangeur (4) pour retourner dans le réservoir (7) au travers de la canalisation (4). Thus described, the operation of the assembly is thus summarized when the touch cell detects the heating of the water coming from the hot water supply (10) the inlet of cold water is injected at the mixer (4). ). When the user stops using water, the excess hot water is stored in the mixer (4) to return to the tank (7) through the pipe (4).

Lorsque l'utilisateur commande de nouveau de l'eau chaude ou tiède à la température voulue, le mélange eau froide conservé dans le réservoir (7) est pulsé par la pompe (8) au niveau du mélangeur (4) et évacué par le robinet (1). When the user re-orders warm or warm water at the desired temperature, the cold water mixture kept in the tank (7) is pulsed by the pump (8) at the mixer (4) and discharged through the tap (1).

On a représenté sur la figure 2 de la planche 2/2, le montage d'un dispositif 15 d'une installation investie sur un ensemble collectif. FIG. 2 of the board 2/2 shows the installation of a device 15 of an installation invested in a collective unit.

L'alimentation est assurée par un robinet (1) doté d'une cellule tactile (15) programmable qui constitue le moyen de détecter la présence à distance d'un objet à nettoyer à volume variable et arrête l'eau quand elle s'écoule froide. La commande de l'écoulement de l'eau ou de son arrêt est pilotée au moyen d'un coffret de commande (17) au boîtier de programmation (16) et à la vanne (2) de forme conique réalisée en téflon par exemple. The supply is provided by a tap (1) having a programmable touch cell (15) which is the means of detecting the remote presence of a variable volume cleaning object and stops the water when it flows. cold. The control of the flow of water or its shutdown is controlled by means of a control box (17) to the programming box (16) and the valve (2) of conical shape made of Teflon for example.

25 L'arrivée d'eau dont le volume et le débit est contrôlé par le compteur (12) est pulsée au moyen de la pompe (8) qui stocke l'eau froide dans le réservoir (7) puis dans le mélangeur (4) avec l'eau chaude issue de la canalisation (10) afin d'obtenir une température satisfaisante au niveau du robinet (1). The inlet of water whose volume and flow rate is controlled by the meter (12) is pulsed by means of the pump (8) which stores the cold water in the reservoir (7) and then in the mixer (4) with the hot water from the pipe (10) to obtain a satisfactory temperature at the tap (1).

30 Le fonctionnement du mélangeur (4) est obtenu au moyen d'un axe (21) en forme conique réalisé en matériau non adhérent au calcaire et assumer par un 20 mouvement de brassage type va et vient destiné à fermer temporairement le conduit dirigé vers le mitigeur (1) ou la cuve dotée le clapet anti retour (23). Le mélangeur (4) est alimenté à la fois par le conduit d'eau chaude et d'eau froide dont la régulation est programmée au moyen de la commande électronique (16) relié au capteur de température et de pression (3) et (19). 15 20 25 30 The operation of the mixer (4) is obtained by means of a conically shaped shaft (21) made of a non-limestone adhering material and to assume by a reciprocating brewing movement intended to temporarily close the conduit directed towards the mixing valve (1) or the tank equipped with the non-return valve (23). The mixer (4) is fed both by the hot and cold water pipe whose regulation is programmed by means of the electronic control (16) connected to the temperature and pressure sensor (3) and (19). ). 15 20 25 30
