"UN SISTEMA DI PROTEZIONE CONTRO LA CONDENSA PER UNA UNIT? DI COMANDO DI AUTOCLAVE" "A PROTECTION SYSTEM AGAINST CONDENSATION FOR AN AUTOCLAVE CONTROL UNIT"
DESCRIZIONE DESCRIPTION
Il presente trovato si riferisce ad un gruppo autoclave perfezionato comprendente una motopompa ed un serbatoio di accumulo a pressione, il sistema essendo atto a fornire un fluido a pressione in un impianto di distribuzione di fluido ed in particolare del tipo descritto nel Brevetto Italiano n?1343261 e nel corrispondente Brevetto Europeo n? 1479911 degli stessi richiedenti. The present invention relates to an improved autoclave unit comprising a motor pump and a pressure accumulation tank, the system being able to supply a fluid under pressure in a fluid distribution system and in particular of the type described in the Italian Patent No. 1343261 and in the corresponding European Patent n? 1479911 by the same applicants.
Nel gruppo autoclave del Brevetto citato, l'elettropompa viene azionata mediante una centralina di comando elettrico sulla base di sensori di pressione e di portata del fluido in uscita dalla pompa. Tale centralina comprende una scheda elettronica installata in una camera ricavata fra un corpo principale applicato al serbatoio a pressione ed un coperchio di protezione. Poich? detto corpo principale, al quale sono applicati i sensori, ? attraversato dall'acqua erogata dalla pompa, esso tende ad assumere la temperatura dell'acqua e, quando le condizioni ambientali locali di temperatura ed umidit? lo consentono, l'umidit? atmosferica tende a condensare su di esso e su quanto ? contenuto in detta camera e quindi ad accumularsi nella camera stessa, con possibilit? di compromettere la funzionalit? della scheda elettronica ivi contenuta. In the autoclave unit of the cited patent, the electric pump is operated by means of an electric control unit on the basis of pressure and flow rate sensors of the fluid leaving the pump. This control unit comprises an electronic board installed in a chamber formed between a main body applied to the pressure tank and a protective cover. Since? said main body, to which the sensors are applied,? crossed by the water delivered by the pump, it tends to assume the temperature of the water and, when the local environmental conditions of temperature and humidity? allow it, the humidity? atmospheric tends to condense on it and on how much? contained in said chamber and therefore to accumulate in the chamber itself, with the possibility? to compromise the functionality? of the electronic board contained therein.
Scopo del presente trovato ? quello di evitare tale inconveniente. Secondo il trovato, fra il coperchio e detto corpo principale ? ricavato un percorso a labirinto di deflusso dell'acqua di condensa per gravit?. Inoltre il sensore di pressione, che sporge dal corpo principale, ? posto sotto e/o defilato in pianta rispetto alla scheda in modo da evitare di gocciolare condensa sulla scheda elettronica. Purpose of the present invention? to avoid this inconvenience. According to the invention, between the lid and said main body? obtained a labyrinth path for the outflow of condensate water by gravity. Furthermore, the pressure sensor, which protrudes from the main body,? placed under and / or in the plan with respect to the board in order to avoid condensation dripping onto the electronic board.

Fig.6 mostra il dettaglio VI della Fig.5 ingrandito. Fig.6 shows the detail VI of Fig.5 enlarged.
Con riferimento alla Fig.1, il gruppo autoclave comprende un serbatoio di accumulo 1 sopra al quale ? fissata una elettropompa 3, al serbatoio di accumulo 1 essendo applicata una centralina di comando 5 del gruppo. La centralina di comando 5 comprende un corpo principale 5A (vedere Figg.4 e seguenti) entro il quale ? ricavato un passaggio secondo le frecce F (Fig.5) per il fluido pompato dalla elettropompa fra un boccaglio d'ingresso 5B ed un boccaglio d'uscita 5C, ed a tale passaggio sono applicati un sensore di pressione 7 ed un sensore di flusso 9. With reference to Fig. 1, the autoclave group comprises an accumulation tank 1 above which? an electric pump 3 is fixed, a control unit 5 of the unit being applied to the storage tank 1. The control unit 5 comprises a main body 5A (see Figs. 4 and following) within which? obtained a passage according to the arrows F (Fig. 5) for the fluid pumped by the electric pump between an inlet nozzle 5B and an outlet nozzle 5C, and a pressure sensor 7 and a flow sensor 9 are applied to this passage .
Su una parete del corpo principale 5A ? applicata una scheda elettronica 5D atta a pilotare la elettropompa 3 in base ai segnali ricevuti dai sensori 7, 9. Un coperchio 11 ? applicato al corpo principale 5A della centralina fissandolo mediante viti (non mostrate) contro un bordo 5E sporgente dal corpo 5A. On a wall of the main body 5A? an electronic board 5D is applied to drive the electric pump 3 on the basis of the signals received from the sensors 7, 9. A cover 11? applied to the main body 5A of the control unit, fixing it by means of screws (not shown) against an edge 5E protruding from the body 5A.
La scheda elettronica 5D non ? a contatto diretto con la parete del corpo 5A alla quale ? fissata, ma fra essa e tale parete sono interposti appositi distanziali 4 (Fig.5) che hanno l'effetto di impedire una trasmissione diretta di calore fra la parete e la scheda. Inoltre, come si vede dalla Fig.4, la scheda 5D ? disposta in parte al di sopra ed in parte defilata in pianta rispetto al sensore di pressione 7. The 5D electronic board is not? in direct contact with the body wall 5A to which? fixed, but between it and this wall are interposed special spacers 4 (Fig. 5) which have the effect of preventing a direct transmission of heat between the wall and the board. Also, as shown in Fig. 4, the 5D? arranged partly above and partly withdrawn in plan with respect to the pressure sensor 7.
Il corpo 5A ed il sensore di pressione 7, essendo a contatto diretto con il fluido che passa fra i boccagli 5B, 5C, tendono ad assumere la temperatura di questo che, in genere, ? inferiore alla temperatura ambiente. Tuttavia, con la disposizione secondo il trovato sopra descritta, la scheda 5D non pu? ricevere eventuale condensa che, in climi caldi ed umidi, potrebbe formarsi sulla superficie esterna del corpo 5A e sul sensore 7. The body 5A and the pressure sensor 7, being in direct contact with the fluid passing between the nozzles 5B, 5C, tend to assume the temperature of this which, in general, is? lower than ambient temperature. However, with the arrangement according to the invention described above, the card 5D cannot? receive any condensation which, in hot and humid climates, could form on the external surface of the body 5A and on the sensor 7.
Inoltre, secondo il trovato, nella parte inferiore del bordo 5E del corpo 5A (vedere anche Fig.6) sono ricavate due aperture 5F e fra il bordo 5E ed il coperchio 11 della centralina ? lasciata una intercapedine (e), ponendo cos? in comunicazione di fluido la camera in cui ? installata la scheda 5D con l'esterno ma nel contempo assicurando la protezione della scheda 5D da spruzzi d'acqua dall'esterno, come richiesto dal grado di protezione IP X5. In tal modo la condensa che si fosse raccolta nella parte inferiore di detta camera pu? defluire e scaricarsi all'esterno di questa attraverso un percorso a labirinto, evitando di allagare detta camera e quindi la scheda. Furthermore, according to the invention, in the lower part of the edge 5E of the body 5A (see also Fig. 6) there are two openings 5F and between the edge 5E and the cover 11 of the control unit? left an interspace (e), placing cos? in fluid communication the chamber in which? installed the 5D card with the outside but at the same time ensuring the protection of the 5D card from water splashes from the outside, as required by the degree of protection IP X5. In this way the condensate that had collected in the lower part of said chamber can? flow and discharge outside this through a labyrinth path, avoiding flooding said chamber and therefore the board.
