Descrizione del brevetto per invenzione industriale avente per titolo: Description of the patent for industrial invention entitled:
“SISTEMA IDRAULICO PER L'EROGAZIONE DOSATA DI ADDITIVI IN UN APPARECCHIO IDRO-SANITARIO "HYDRAULIC SYSTEM FOR DOSED DISPENSING OF ADDITIVES IN A HYDRO-SANITARY APPLIANCE
La presente invenzione si riferisce ad un sistema idraulico per l’erogazione dosata di additivi, quali sostanze aromatiche o simili, in un apparecchio idro-sanitario come ad esempio una cabina attrezzata per doccia. The present invention refers to a hydraulic system for the metered dispensing of additives, such as aromatic substances or the like, in a hydro-sanitary appliance such as a shower cubicle.
Sono ben note cabine per doccia variamente attrezzate per indurre nell’utente sensazioni psicofisiche di benessere mediante l’erogazione, eventualmente combinata, di acqua, vapori, suoni, luci, aromi, ecc. Variously equipped shower cabins are well known to induce psychophysical sensations of well-being in the user by supplying, possibly combined, water, vapors, sounds, lights, aromas, etc.
Per quanto riguarda gli aromi, però, che normalmente sono disponibili sotto forma di oli idrosolubili che richiederebbero una dosatura precisa e una forte diluizione, è stato finora praticamente impossibile prevederne una corretta erogazione automatica in quantità e proporzioni ottimali, cioè tali da aromatizzare l’ambiente in cui si trova una persona in maniera adeguata alle diverse circostanze. As for the aromas, however, which are normally available in the form of water-soluble oils that would require precise dosing and strong dilution, it has so far been practically impossible to predict a correct automatic dispensing in optimal quantities and proportions, i.e. such as to aromatize the environment. in which a person is located in a manner appropriate to the different circumstances.
Tale problema è particolarmente accentuato nel caso di una cabina per doccia, dato che - a differenza di quanto avviene in una vasca da bagno - l’utente non è immerso in una massa d’acqua, ma viene soltanto investito da getti di acqua e/o vapore. This problem is particularly accentuated in the case of a shower enclosure, since - unlike what happens in a bathtub - the user is not immersed in a mass of water, but is only hit by jets of water and / or steam.
Nelle vasche da bagno, peraltro, è noto immettere oli aromatizzanti in una massa d’acqua mediante uno o più iniettori che, mediante un comando manuale o semiautomatico, sono alimentati da corrispondenti serbatoi multi-dose. Pertanto, la dosatura degli aromi risulta indesideratamente approssimativa. In bathtubs, however, it is known to introduce flavoring oils into a mass of water by means of one or more injectors which, by means of a manual or semi-automatic control, are fed by corresponding multi-dose tanks. Therefore, the dosage of the aromas is undesirably approximate.
In ogni caso, poiché nelle vasche da bagno gli oli vengono immessi nella massa d’acqua nella loro normale condizione molto concentrata, è necessario in seguito agitare accuratamente l’acqua stessa per realizzare un’accettabile aromatizzazione dell’ambiente. In any case, since in the bathtubs the oils are introduced into the mass of water in their normal very concentrated condition, it is then necessary to carefully shake the water itself to achieve an acceptable aromatization of the environment.
Sarebbe pertanto auspicabile, ed è lo scopo principale della presente invenzione, fornire un sistema idraulico per l'erogazione automatica dosata di additivi in un apparecchio idro-sanitario il quale sia non solo semplice ed affidabile, ma permetta anche un’efficace erogazione di additivi in proporzioni particolarmente precise, secondo i casi e le necessità. It would therefore be desirable, and it is the main object of the present invention, to provide a hydraulic system for the automatic metered dispensing of additives in a hydro-sanitary appliance which is not only simple and reliable, but also allows an effective dispensing of additives in particularly precise proportions, according to cases and needs.
Un altro scopo dell'invenzione è quello di fornire un sistema idraulico del tipo citato il quale abbia una sostanziale autonomia e permetta quindi di erogare dosi multiple di additivi. Another object of the invention is to provide a hydraulic system of the aforementioned type which has substantial autonomy and therefore allows multiple doses of additives to be dispensed.
Secondo l'invenzione, tali scopi sono ottenuti in un sistema idraulico per l’erogazione automatica dosata di additivi in un apparecchio idro-sanitario incorporante le caratteristiche delle rivendicazioni allegate. According to the invention, these purposes are achieved in a hydraulic system for the automatic metered dispensing of additives in a hydro-sanitary appliance incorporating the features of the attached claims.
Le caratteristiche ed i vantaggi dell'invenzione saranno chiariti dalla seguente descrizione, avente solo titolo di esempio non limitativo, con riferimento all’unita figura, che mostra schematicamente e parzialmente un apparecchio idro-sanitario incorporante un sistema idraulico secondo una forma preferita di realizzazione. The characteristics and advantages of the invention will be clarified by the following description, having only a non-limiting example, with reference to the attached figure, which schematically and partially shows a hydro-sanitary appliance incorporating a hydraulic system according to a preferred embodiment.
Nell’esempio che si descrive si fa riferimento ad una cabina per doccia di tipo automatico comprendente almeno una parete 1 variamente attrezzata, ad esempio con una pluralità di ugelli 2 per getti d’acqua dorsali, almeno un ugello nebulizzatore 3, una seduta 4, una sporgenza superiore 5 di appoggio e contenimento, nonché mezzi di comando (schematicamente indicati con 6) per l’azionamento automatico dei principali organi operativi sotto il controllo di una centralina elettronica (non mostrata), o simile. In the example described, reference is made to an automatic shower enclosure comprising at least one wall 1 variously equipped, for example with a plurality of nozzles 2 for back water jets, at least one nebulizer nozzle 3, a seat 4, an upper projection 5 for supporting and containing, as well as control means (schematically indicated with 6) for the automatic actuation of the main operating members under the control of an electronic control unit (not shown), or the like.
Il sistema idraulico secondo l'invenzione si presta ad essere sostanzialmente alloggiato sul retro della parete 1 e comprende almeno un serbatoio di immagazzinamento 7 per ciascun additivo che si desidera erogare. The hydraulic system according to the invention lends itself to being substantially housed on the rear of the wall 1 and comprises at least one storage tank 7 for each additive to be dispensed.
Si noti che per semplicità descrittiva il sistema idraulico mostrato nelle figure è relativo ad un solo additivo, che preferibilmente è formato da olio aromatizzante idrosolubile in forma sostanzialmente concentrata. It should be noted that for the sake of simplicity of description, the hydraulic system shown in the figures relates to a single additive, which is preferably formed of water-soluble flavoring oil in a substantially concentrated form.
Il serbatoio 7 è di tipo multi-dose e preferibilmente comprende un sensore di livello 8, o simile, atto a segnalare opportunamente, ad esempio con un'indicazione visiva, una sostanziale condizione di vuoto. The tank 7 is of the multi-dose type and preferably comprises a level sensor 8, or the like, suitable for suitably signaling, for example with a visual indication, a substantial vacuum condition.
A questo proposito, il serbatoio 7 può essere riempito per gravità attraverso un’associata apertura chiudibile di caricamento 9 che è preferibilmente disposta in corrispondenza della sporgenza superiore 5 e collegata al serbatoio stesso attraverso un tubo discendente 10. In this regard, the tank 7 can be filled by gravity through an associated closable loading opening 9 which is preferably arranged at the upper projection 5 and connected to the tank itself through a descending tube 10.
Un ulteriore tubo discendente 11 collega la parte inferiore del serbatoio 7, attraverso un’elettrovalvola 12, o simile, al cielo di un sottostante contenitore 13 di miscelazione. A further descending pipe 11 connects the lower part of the tank 7, through a solenoid valve 12, or similar, to the top of an underlying mixing container 13.
Il contenitore 13 è atto ad essere alimentato con acqua di rete attraverso un tubo 15 associato ad un’elettrovalvola 14, o simile, e il suo fondo è collegato all’aspirazione di una pompa 16 la cui mandata è collegata ad uno o più ugelli nebulizzatori 3 attraverso un tubo 17. Inoltre, il fondo del contenitore 13 è collegato ad un tubo di scarico 18 attraverso un'elettrovalvola 19, un rubinetto o simile, The container 13 is adapted to be fed with mains water through a tube 15 associated with a solenoid valve 14, or the like, and its bottom is connected to the suction of a pump 16 whose delivery is connected to one or more nebulizer nozzles. 3 through a tube 17. Furthermore, the bottom of the container 13 is connected to a discharge tube 18 through a solenoid valve 19, a tap or the like,
Preferibilmente, il contenitore 13 è provvisto di un sensore di livello 20, o simile, atto a pilotare la centralina della cabina analogamente al sensore di livello 8. Preferably, the container 13 is provided with a level sensor 20, or the like, adapted to drive the cabin control unit in the same way as the level sensor 8.
Le elettrovalvole 12, 14 e 19, nonché la pompa 16, devono intendersi controllate dalla centralina della cabina nel modo che sarà descritto in seguito. The solenoid valves 12, 14 and 19, as well as the pump 16, are to be understood as being controlled by the cabin control unit in the manner described below.
Quando si desidera aromatizzare l’ambiente interno della cabina, l’elettrovalvola 12 viene temporaneamente aperta per permettere ad una quantità corrispondentemente dosata di additivo di fluire per gravità dal serbatoio 7 all’interno del contenitore 13, dove esso viene miscelato con acqua immessa grazie all’apertura dell’elettrovalvola 14 fino al raggiungimento di un livello prestabilito dal sensore 20. When it is desired to aromatize the interior environment of the booth, the solenoid valve 12 is temporarily opened to allow a correspondingly dosed quantity of additive to flow by gravity from the tank 7 into the container 13, where it is mixed with water introduced thanks to the '' opening of the solenoid valve 14 until a predetermined level is reached by the sensor 20.
Il contenitore 13 si comporta pertanto da misuratore volumetrico, quindi particolarmente semplice e preciso, in cui l’olio aromatizzante viene fortemente diluito in maniera vantaggiosamente omogenea grazie alla forte agitazione provocata dal getto d’acqua proveniente dal tubo 15. The container 13 therefore acts as a volumetric meter, therefore particularly simple and precise, in which the flavoring oil is strongly diluted in an advantageously homogeneous way thanks to the strong agitation caused by the jet of water coming from the tube 15.
A questo proposito, infatti, l’elettrovalvola 14 viene preferibilmente aperta contemporaneamente o successivamente all’elettrovalvola 12, in modo tale da “omogeneizzare” sostanzialmente l’additivo, che può essere relativamente denso e/o può avere peso specifico relativamente diverso dall’acqua, formando nel contenitore 13 una miscela a preparazione “istantanea". In this regard, in fact, the solenoid valve 14 is preferably opened simultaneously or subsequently to the solenoid valve 12, in such a way as to substantially "homogenize" the additive, which may be relatively dense and / or may have a specific weight relatively different from water. , forming in the container 13 an "instant" mixture.
Subito dopo, viene avviata la pompa 16 (in modo continuo o discontinuo) per erogare la miscela all’interno della cabina attraverso gli ugelli nebulizzatori 3. Poiché l'additivo (o gli additivi, secondo i casi) erogato dagli ugelli 3 è già correttamente diluito, l'erogazione stessa può essere vantaggiosamente prolungata nel tempo (fino a svuotamento del contenitore 13), col vantaggio di realizzare in modo persistente, e quindi veramente efficace, una condizione di corretta aromatizzazione all’interno della cabina per doccia. Immediately afterwards, the pump 16 is started (continuously or discontinuously) to deliver the mixture inside the booth through the spray nozzles 3. Since the additive (or additives, as appropriate) delivered by the nozzles 3 is already correctly diluted, the delivery itself can be advantageously prolonged over time (until the container 13 is emptied), with the advantage of providing a condition of correct aromatization inside the shower cubicle in a persistent and therefore truly effective manner.
Si noti che la suddetta preparazione istantanea nel contenitore 13 di una miscela acqua-additivo adeguatamente dosata e proporzionata permette ulteriori importanti vantaggi: It should be noted that the aforementioned instantaneous preparation in the container 13 of an adequately dosed and proportioned water-additive mixture allows further important advantages:
- riduzione dei consumi, dato che viene preparata soltanto la quantità di miscela più adatta al programma operativo selezionato; - reduction in consumption, since only the quantity of mixture most suited to the selected operating program is prepared;
- sfruttamento ottimale delle proprietà intrinseche dell’additivo, dato che esso viene mantenuto integro fino a quando non dev’essere effettivamente utilizzato. - optimal exploitation of the intrinsic properties of the additive, since it is kept intact until it is actually used.
Naturalmente, il sistema idraulico descritto può subire numerose modifiche rientranti nell'ambita dell’invenzione. Of course, the hydraulic system described can undergo numerous modifications falling within the scope of the invention.
Ad esempio, aprendo l'elettrovalvola 19 è possibile svuotare e lavare sostanzialmente l’intero circuito, in modo da predisporlo all’erogazione di un additivo diverso, quale una sostanza disinfettante per periodiche operazioni di disinfezione igienica. For example, by opening the solenoid valve 19 it is possible to essentially empty and wash the entire circuit, in order to prepare it for the delivery of a different additive, such as a disinfectant substance for periodic hygienic disinfection operations.
A questo proposito, va ricordato che il sistema idraulico secondo l’invenzione può essere vantaggiosamente applicato, senza alcuna sostanziale modifica di principio, anche ad un apparecchio idro-sanitario quale una vasca da bagno, in particolare una vasca per idromassaggio. In this regard, it should be remembered that the hydraulic system according to the invention can be advantageously applied, without any substantial modification of principle, also to a hydro-sanitary appliance such as a bathtub, in particular a whirlpool tub.
Ovviamente, i nebulizzatori 3 potranno essere sostituiti da ugelli erogatori di tipo diverso. Obviously, the nebulizers 3 can be replaced by dispensing nozzles of a different type.
