Abstract
Description
-1- La présente invention a pour objet un dispositif permettant 5 l'obtention d'eau chaude instantanée. The present invention relates to a device for obtaining instantaneous hot water.
Elle se rapporte d'une manière générale au domaine industriel et commercial de la fabrication et de la diffusion d'appareils destinés à délivrer de l'eau chaude en tout point d'utilisation pouvant disposer d'une source d'eau chaude ou 10 froide et d'une alimentation électrique. It relates generally to the industrial and commercial field of the manufacture and distribution of apparatus for delivering hot water to any point of use that may have a source of hot or cold water. and a power supply.
Actuellement, la distribution d'eau chaude est généralement effectuée à partir de chauffe-eau électriques ou à gaz communs à plusieurs points d'utilisation et plus ou moins éloignés de ces derniers. En particulier, dans les 15 copropriétés, sont fréquemment installés des systèmes à accumulation de grande capacité reliés à des réseaux de tuyauteries de longueur importante. Durant les période de non utilisation, l'eau contenue dans ces réseaux, souvent non isolés, se refroidit et l'utilisateur d'eau chaude doit attendre un certain temps avant que l'eau tiède ou froide contenue dans la tuyauterie 20 d'alimentation se soit écoulée. Il s'ensuit un gaspillage d'eau et une perte d'énergie relativement importants, cette perte d'énergie étant aggravée dans les cas des systèmes à accumulation par le fait qu'une grande quantité d'eau est obligatoirement maintenue chauffée en permanence, quelle que soit le volume réellement utilisé. 25 Le dispositif selon la présente invention a pour objectif de remédier à cet état de choses. Il permet en effet de délivrer de l'eau chaude partout où il en est besoin et sans attendre, l'eau chaude étant immédiatement disponible, dès que l'on tourne le robinet ou le mitigeur. 30 Il permet une forte diminution du gaspillage inutile de l'eau, seule la quantité exacte d'eau nécessaire étant chauffée. L'électricité n'est consommée que pendant la production de l'eau chaude, ce qui entraîne une forte diminution de sa consommation et une économie sensible. De plus, le système selon l'invention permet, même en cas de dysfonctionnement de l'un de ses éléments, de disposer néanmoins d'eau chaude aux autres points d'utilisation, ce que ne permet absolument pas un système centralisé d'eau chaude. Currently, the distribution of hot water is generally carried out from electric water heaters or gas common to several points of use and more or less distant from them. In particular, in condominiums, high capacity storage systems connected to long pipe networks are frequently installed. During periods of non-use, the water contained in these networks, often uninsulated, cools and the user of hot water has to wait a certain time before the warm or cold water contained in the supply pipe 20 has passed. This results in a significant waste of water and a loss of energy, this loss of energy being aggravated in the case of accumulation systems in that a large amount of water is necessarily kept permanently heated, whatever the volume actually used. The purpose of the device according to the present invention is to remedy this state of affairs. It allows to deliver hot water wherever it is needed and without waiting, hot water being immediately available, as soon as you turn the tap or mixer. It allows a great reduction in unnecessary waste of water, only the exact amount of water needed being heated. Electricity is consumed only during the production of hot water, which leads to a sharp decrease in consumption and a sensible economy. In addition, the system according to the invention allows, even in case of malfunction of one of its elements, nevertheless to have hot water at other points of use, which absolutely does not allow a centralized water system hot.

Le dispositif, figures 1 à 7, est constitué d'un boîtier 1 étanche 1 -2- 25 30 -3-comportant une arrivée d'eau 2 et une sortie d'eau 3. In the accompanying drawings, given by way of non-limiting examples of embodiments of the subject of the invention: FIGS. 1 and 2 show two housing variants seen from the front, FIG. 3 shows the housing seen from the following side FIG. 4 is an enlarged cross section passing between the planar walls of the housing, along the arrows F3 of FIG. 3; FIG. 5 is an enlarged cross section perpendicular to the planar walls of the housing, according to FIGS. arrows F2 of Figure 1, Figure 6 is a horizontal section along the arrows F4 of Figure 4 showing a housing consisting of two shells ernboîtées assembled by gluing. FIG. 7 is an enlarged transverse section passing between the flat walls of a housing variant, along the arrows F3 of FIG. 3, and FIG. 8 is a horizontal section along the arrows F5 of FIG. 7. The device, FIGS. 7, consists of a sealed housing 1 -2- 25 -3-comprising a water inlet 2 and a water outlet 3.
Le boîtier 1 comporte deux parois internes planes 4, 5 parallèles reliée par une paroi périphérique 6. The casing 1 comprises two parallel flat inner walls 4, 5 connected by a peripheral wall 6.
Deux inducteurs 7 à résistance électrique sont plaqués sur la face externe des parois planes 4, 5 qui sont conductrices de la chaleur. Un isolant thermique 8 entoure l'ensemble du boîtier et des inducteurs. Two inductors 7 electrical resistance are plated on the outer face of the flat walls 4, 5 which are heat conducting. Thermal insulation 8 surrounds the entire housing and inductors.
Sur la face interne des parois planes 4, 5 sont fixées des lamelles métalliques 9 disposées de manière à créer un labyrinthe continu de grande longueur serpentant depuis l'arrivée 2 jusqu'à la sortie d'eau 3. Ces lamelles pourront avantageusement être en forme d'escalier (figure 4), de façon à augmenter la surface en contact avec l'eau pour accélérer son 15 élévation de température. Elle pourront également être rectilignes et parallèles (figures 7, 8) ou présenter toute autre configuration permettant une longueur de parcours et une surface de contact avec l'eau entre l'arrivée d'eau 2 et la sortie 3 aussi grandes que possible. 20 Le boîtier 1 pourra être constitué de deux coques s'emboîtant l'une dans l'autre, comportant chacune une paroi plane 4, 5 et assemblées par collage au moyen d'un cordon périphérique 10 assurant l'étanchéité de l'ensemble (figure 6).
