“CENTRALINA PER IMPIANTI ASPIRAPOLVERE CENTRALIZZATI” "POWER UNIT FOR CENTRALIZED VACUUM CLEANER SYSTEMS"
DESCRIZIONE DESCRIPTION
Ormai da molti anni gli impiantì aspirapolvere centralizzati vengono preferiti, laddove è possibile, agli aspirapolvere tradizionali, ovvero a quegli elettrodomestici rumorosi che, trascinati per tutta Sa casa, rimettono in cìrcolo Farla aspirata e mal perfettamente filtrata. For many years now, centralized vacuum cleaners have been preferred, wherever possible, to traditional vacuum cleaners, that is to say those noisy appliances that, dragged around the house, put them back into circulation.
Notoriamente tali impianti aspirapolvere centralizzati si avvalgono di una centralina collegato alle prese di aspirazione opportunamente distribuite nell'edifìcio da servire mediante una canalizzazione in plastica, sotto traccia oppure In vista. Collegando temporaneamente alle suddette prese appositi accessori simili a quelli degli aspirapolvere tradizionali, la polvere ed i rifiuti aspirati vengono convogliati, attraverso la suddetta canalizzazione, nell'apposito contenitore associato alla centralina che è dotata di un sistema filtrante per separare Parìa da quanto trascinato nelFaspìrazione, It is well known that such centralized vacuum cleaner systems make use of a control unit connected to the suction sockets appropriately distributed in the building to be served by means of a plastic channeling, under the track or in sight. By temporarily connecting special accessories similar to those of traditional vacuum cleaners to the aforementioned sockets, the dust and the sucked waste are conveyed, through the aforementioned channel, to the appropriate container associated with the control unit which is equipped with a filtering system to separate Parìa from what is dragged into the suction,
Detta centralina, dalie dimensioni particolarmente ingombranti, è generalmente installata in un locale di servizio o all’aperto in un punto riparato anche per via della rumorosità che, sebbene contenuta, risulta comunque fastidiosa all'interno di un'abitazione. This control unit, due to its particularly bulky dimensions, is generally installed in a service room or outdoors in a sheltered spot also due to the noise which, although contained, is still annoying inside a home.
Scopo del presente trovato è quello di offrire una centralina aspirante più funzionale di quelle attualmente in uso in termini di contenimento degli ingombri, di semplicità e reversibilità d'installazione e di comodità di utilizzo, nonché di ridurne in maniera significativa la rumorosità senza ricorrere ail'appÌÌcazione di ingombranti ed antiestetici silenziatori esterni alla centralina stessa. The purpose of the present invention is to offer a more functional suction unit than those currently in use in terms of containment of dimensions, simplicity and reversibility of installation and ease of use, as well as to significantly reduce noise without resorting to application of bulky and unsightly silencers external to the control unit itself.
Le caratteristiche innovative della suddetta centralina sono di seguito descritte con l'ausilio di cinque tavole di disegno dove, a solo titolo indicativo e non limitativo, sono rappresentate: The innovative features of the aforementioned control unit are described below with the aid of five drawing tables where, for indicative and non-limiting purposes only, are represented:
la FIG, 1 , che mostra una vista laterale della centralina in oggetto; - la FIG, 2 che mostra la sezione verticale XX relativa alla FIG. 1 ; FIG, 1, which shows a side view of the control unit in question; - FIG, 2 showing the vertical section XX relating to FIG. 1;
- la FIG. 3 che mostra la vista assonometrica esplosa della centra delle FIGG. 1 e 2; - FIG. 3 showing the exploded axonometric view of the center of FIGS. 1 and 2;
le FIGO. 4 e 5 che mostrano la vista frontale e la vista laterale centralina in fase di rimozione del contenitore delle polveri previo sblocco dei mezzi di aggancio del medesimo al soprastante stadio centrale; the FIGO. 4 and 5 which show the front view and the side view of the control unit during the removal phase of the powder container after releasing the means for hooking the same to the above central stage;
le FiGG. 6 e 7 e le FIGG, 8 e 9 che mostrano le viste frontali e le sezioni verticali dei due elementi recìprocamente agganciabili, come alla FIG. 10, per il mantenimento in chiusura del contenitore delle polveri; the FIGS. 6 and 7 and Figs, 8 and 9 which show the front views and the vertical sections of the two elements which can be connected reciprocally, as in FIG. 10, to keep the dust container closed;
le FIGG. 11-12-13, che mostrano una vista laterale e due sezioni verticali della centralina provvista del gruppo di autopulizia del filtro* Dall'esame del disegni allegati ed iniziando da quelli dalle FIGG. 1-2-3, si evince che la centralina ir oggetto comprende un corpo o stadio centrale 4 provvisto del condotto 500 di Ingresso dell'aria aspirata e che, chiuso superiormente da una sorta di coperchio o stadio di testa 9 recante il condotto 901 di uscita dell'aria filtrata ed il pannello di controllo 903 per l'interfaccia con l'utente, è completato Inferiormente da un contenitore 1 per la raccolta delle polveri provvisto di una sorta di imbuto 104 che, destinato al fissaggio dell'apposito sacchetto raccoglipolvere, è bordato da una guarnizione di tenuta 105 mantenuta premuta fra il sottostante contenitore 1 ed il soprastante stadio centrale 4. FIGS. 11-12-13, which show a side view and two vertical sections of the control unit provided with the filter self-cleaning unit * From the examination of the attached drawings and starting from those of FIGS. 1-2-3, it can be seen that the control unit of the subject comprises a central body or stage 4 provided with the intake duct 500 for the intake air and which, closed at the top by a sort of lid or head stage 9 carrying the duct 901 filtered air outlet and the control panel 903 for the interface with the user, is completed at the bottom by a container 1 for collecting the dust provided with a sort of funnel 104 which, intended for fixing the special dust collection bag, it is bordered by a sealing gasket 105 kept pressed between the underlying container 1 and the above central stage 4.
Detto contenitore 1 è dotato di un sistema di aggancio e sgancio rapidi alio stadio centrale 4 per essere agevolmente rimosso ed inserito mediante semplici movimenti frontali eseguibili da una sola manualmente e senza attrezzi, A tale scopo, come visibile alle FIGG, 4 e 5, un man rgl ione 3 pressoché semicircolare è imperniato, nelle propria, sedi 301, all'esterno dello stadio centrale 4 nelle corrispondenti sedi 401, in modo che, premendo un pulsante a scatto 102 (FIGG, 6-7-8-9-10), stabilmente applicato al contenitore delle polveri 1 nell'apposita sede frontale 101 ed agganciente dal basso, con una propria porzione ad uncino 103, un apposito rilievo 302 del maniglione 3, lo sgancio del suddetto rilievo 302 consenta ai contenitore 1 di rimanere appeso al di sotto del maniglione 3, che sì dispone inclinato molando intorno ai perni 301-401, grazie ad una coppia di risalti cilìndrici 300 impegnati in altrettanti incavi 100 appositamente ricavati sulla superficie esterna del contenitore 1, In tal modo appeso, detto contenitore 1 può essere afferrato con entrambe le mani e facilmente rimosso per la sostituzione del sacchetto di raccolta delle polveri, fra l'altro provvisto di apposito tendi sacco. Said container 1 is equipped with a quick coupling and release system to the central stage 4 to be easily removed and inserted by means of simple frontal movements which can be carried out by one only manually and without tools. For this purpose, as can be seen in FIGS, 4 and 5, a almost semicircular handle 3 is hinged, in its own seats 301, outside the central stage 4 in the corresponding seats 401, so that, by pressing a snap button 102 (FIGG, 6-7-8-9-10) , stably applied to the powder container 1 in the appropriate front seat 101 and hooking from below, with its own hooked portion 103, a special relief 302 of the handle 3, the release of the aforementioned relief 302 allows the container 1 to remain hanging above under the handle 3, which is inclined by grinding around the pins 301-401, thanks to a pair of cylindrical projections 300 engaged in as many recesses 100 specially made on the external surface of the container 1 In this way, when hung, said container 1 can be grasped with both hands and easily removed to replace the dust collection bag, which is also provided with a suitable bag tightener.
La centralina in oggetto consente di contenere il livello di rumorosità grazie al fatto che il gruppo motore-girante 7 non è fissato con viti allo stadio centrale 4, come nelle attuati centraline, ma vi è semplicemente fermato dall'essere frapposto ad una coppia di guarnizioni antivibranti in gomma 700 e 701 di cui quest' ultima, ovvero quella superiore sagomata per essere fermata in appositi riscontri del motore 7, é rovesciabile per adattarla a due dimensioni del motore stesso che, fra l'altro, essendo decisamente contenute, conferiscono alia centralina un design compatto e d<’>ingombro limitato. The control unit in question allows to contain the noise level thanks to the fact that the motor-impeller unit 7 is not fixed with screws to the central stage 4, as in the control units, but is simply stopped there from being interposed with a pair of gaskets rubber antivibration mounts 700 and 701 of which the latter, or the upper one shaped to be stopped in special stops of the motor 7, is reversible to adapt it to two dimensions of the motor itself which, among other things, being decidedly contained, give the control unit a compact design and limited footprint.
Ma il basso livello dì rumorosità è soprattutto garantito dalla presenza un silenziatore 8 che poggia, all'Interno dello stadio di testa 9, con pluralità di incavi realizzati nella propria base di appoggio corrispondenza di appositi riscontri della guarnizione anti vibrante 701, per offrire all'aria proveniente dal sottostante motore 7 II passaggio obbligato al proprio interno che, conformato a mo' dì labirinto ed interamente rivestito di materiale fonoassorbente, ad esempio poliuretano espanso, presenta un percorso tortuoso dal quale l’aria fuoriesce direttamente nel condotto di espulsione 901 e che, comunque conformato, è caratterizzato dall’avere l'ingresso e l'uscita dell'aria non direttamente affacciati, al fine dì garantire la desiderata diminuzione dell’intensità sonora. But the low noise level is above all guaranteed by the presence of a silencer 8 which rests, inside the head stage 9, with a plurality of recesses made in its own support base corresponding to appropriate abutments of the anti-vibrating gasket 701, to offer the air coming from the underlying motor 7 The forced passage inside which, in the shape of a labyrinth and entirely covered with sound-absorbing material, for example polyurethane foam, has a tortuous path from which the air escapes directly into the expulsion duct 901 and which , however shaped, is characterized by having the air inlet and outlet not directly facing each other, in order to guarantee the desired reduction in sound intensity.
Nella preferita forma di attuazione raffigurata, detto silenziatore 8 comprende un contenitore 800 che, preferibilmente in ABS e realizzato per stampaggio ad iniezione, è chiuso da un coperchio 840 e reca incollati internamente una base 810, una sorta di condotto a labirinto 820 ed un elemento dì chiusura 830 in materiale fonoassorbente. Due aperture 801 ed 802, predisposte su due opposte facce laterali del contenitore 800, sono destinate ad essere posizionate in corrispondenza rispettivamente dell'ingresso e deguscila dell’aria. In the preferred embodiment shown, said silencer 8 comprises a container 800 which, preferably in ABS and made by injection molding, is closed by a lid 840 and internally has a base 810, a sort of labyrinth duct 820 and an element glued internally. closure closure 830 in sound-absorbing material. Two openings 801 and 802, arranged on two opposite side faces of the container 800, are intended to be positioned respectively at the inlet and at the air outlet.
Un’ulteriore caratteristica della centralina in oggetto è quella di essere adattabile alte condizioni dell'impianto da servire essendo predisposta in modo da consentire dì scegliere, direttamente in opera, da quale lato predisporre sia l’entrata dell'aria aspirata che l’uscita dell'aria filtrata, ì’una indipendentemente dall'altra. A further feature of the control unit in question is that of being adaptable to the high conditions of the system to be served, being arranged in such a way as to allow to choose, directly on site, from which side to prepare both the intake air inlet and the outlet of the filtered air, one independently of the other.
In particolare, l’ingresso dell’aria aspirata avviene, In corrispondenza dello stadio centrale 4, attraverso un condotto 500 aggettantesi da un'estremità di un elemento 5 che, fissato con mezzi a vite allo stesso stadio centrate in corrispondenza di due apposite aperture 402 (FIG. 12}, predisposte simmetricamente rispetto al piano verticale mediano della centralina, è perfettamente reversibile in quanto consente dì ottenere l'ingresso dell<’>aria dall'una o dall’altra apertura 402 semplicemente posizionandolo con il proprio condotto 500 in corrispondenza di quella di volta in volta scelta secondo necessità. In particular, the intake of the sucked air takes place, at the central stage 4, through a duct 500 projecting from one end of an element 5 which, fixed with screw means at the same stage centered at two suitable openings 402 (FIG. 12}, arranged symmetrically with respect to the median vertical plane of the control unit, is perfectly reversible as it allows for the entry of air from one or the other opening 402 simply by positioning it with its own duct 500 in correspondence than the one chosen from time to time according to need.
Per quanto concerne l’uscita dell<'>aria filtrata, lo stadio dì testa 9 viene adattato per l'uscita da un lato o dall'altro invertendo la posizione di due paratie laterali 900 e 902 di cui una (900} provvista del condotto di uscita 901 da posizionare in corrispondenza dell’ uscita 802 dei silenziatore 8, opportunamente ruotato a tale scopo durante il suo fissaggio alllntemo dello stesso stadio di testa 9. As regards the outlet of the filtered air, the head stage 9 is adapted for the outlet on one side or the other by inverting the position of two lateral bulkheads 900 and 902, one of which (900} is provided with the duct 901 to be positioned in correspondence with the outlet 802 of the silencer 8, suitably rotated for this purpose during its fastening inside the head stage 9 itself.
La centralina è fìssala a parete mediante pre-montaggio al muro di un'apposita staffa 6 alla quale applicarla successivamente con un semplice accostamento frontale e mediante l'aggancio a scatto di appositi risalti 501, aggettantisi dall'elemento 5 da parte opposta a quella di fissaggio allo stadio centrale 4, nelle corrispondenti sedi 601 predisposte nella staffa 6 e dalle quali vengono all'occorrenza sganciati mediante una semplice pressione su due alette laterali 602, Vantaggiosamente detto sistema di fissaggio frontale consente l'alloggiamento delia centralina In spazi limitati od anche in box da incasso, non necessitando, per il montaggio o per il prelievo dalla staffa di supporto 6, di alcun movimento né laterale né in altezza, All<’>intemo della centralina è previsto che il filtro dell'aria 200, di facile installazione e rimozione poiché sostenuto da una ghiera 201 avvitata nell'estremità inferiore della porzione centrale 403 dello stadio centrale 4, venga protetto da uno scudo cilindrico coassiale 404 che si protende verso il basso quanto basta per intercettare gli eventuali corpi contundenti trasportati dall'aria aspirata. The control unit is fixed to the wall by pre-mounting a special bracket 6 to the wall to which it can be subsequently applied with a simple frontal approach and by snap-hooking special projections 501, projecting from element 5 on the opposite side to that of fixing to the central stage 4, in the corresponding seats 601 arranged in the bracket 6 and from which they are released if necessary by simply pressing on two side wings 602. Advantageously, said front fixing system allows the control unit to be housed in limited spaces or even in built-in box, as it does not require any movement, either sideways or in height, for assembly or removal from the support bracket 6, inside the control unit there is the air filter 200, which is easy to install and removal since it is supported by a ring nut 201 screwed into the lower end of the central portion 403 of the central stage 4, it is protected by a shield coaxial cylindrical 404 which extends downwards just enough to intercept any blunt objects carried by the sucked air.
Il trovato prevede inoltre che la stessa centralina possa essere attrezzata, come alle FIGG, 11-12-13, con un gruppo per S'autopulizia del filtro 200 comprendente un compressore 210 che provvede al riempimento con aria compressa di un serbatoio di accumulo 211 fino a che, al raggiungimento di una determinata pressione preimpostata e rilevata dal pressostato 212, un’elettrovalvola di tipo noto determina l'apertura della valvola a scarico rapido 213 per l'immissione Istantanea, all'interno del suddetto filtro 200 ed attraverso l'ugello 214, di un getto d'aria avente direzione opposta a quella di filtraggio, onde determinare Sa rimozione delle particelle trattenute nei filtro stesso. Detto gruppo di autopulizia, che interviene a cadenze impostabili secondo necessità, è alloggiato fra la guarnizione antivibrante 700 del motore 7 ed il sottostante filtro 200 ed è protetto all’esterno da un carter 2 che, realizzato dì serie per poterlo frapporre fra lo stadio centrale 4 e lo stadio di testa 9 in modo da mantenere Sa compattezza ed il limitato ingombro della centralina, presenta all'interno un condotto centrale 20 per il necessario passaggio detraila aspirata. The invention also provides that the same control unit can be equipped, as in Figures 11-12-13, with a unit for self-cleaning of the filter 200 comprising a compressor 210 which fills with compressed air an accumulation tank 211 up to to that, upon reaching a certain preset pressure and detected by the pressure switch 212, a known type solenoid valve opens the quick exhaust valve 213 for instant injection, inside the aforementioned filter 200 and through the nozzle 214, of an air jet having the opposite direction to that of filtering, in order to determine the removal of the particles retained in the filter itself. Said self-cleaning unit, which intervenes at intervals that can be set according to need, is housed between the anti-vibration gasket 700 of the motor 7 and the underlying filter 200 and is protected on the outside by a casing 2 which, produced as standard to be able to interpose it between the central stage 4 and the head stage 9 in order to maintain the compactness and the limited overall dimensions of the control unit, has inside a central duct 20 for the necessary passage between the suction side.
E’ ovvio che la centralina in oggetto, ferme restando le caratteristiche di massima illustrate e descritte, potrà essere suscettibile dì modifiche o varianti comunque comprese nel presente ambito brevettuale. It is obvious that the control unit in question, without prejudice to the general characteristics illustrated and described, may be susceptible to modifications or variations, however included in this patent area.
