del brevetto per modello industriale di utilità avente per titolo: of the patent for an industrial utility model entitled:
“ARMADIO FRIGORIFERO CON CELLE SEPARATE” "REFRIGERATOR WITH SEPARATE CELLS"
Il presente trovato riguarda un armadio frigorifero, in particolare di tipo per collettività, dotato di almeno due celle separate per conservare diversi tipi di alimenti. The present invention relates to a refrigeration cabinet, in particular of the type for the community, equipped with at least two separate cells for storing different types of food.
Armadi frigoriferi il cui vano intemo è suddiviso in due o più celle nelle quali vengono prodotte temperature diverse, ciascuna adatta per la conservazione di una determinata tipologia di alimenti, sono ampiamente noti nello stato della tecnica. Generalmente, questi armadi frigoriferi sono dotati di circuiti refrigeranti separati che sono dimensionati per assicurare nella rispettiva cella il mantenimento della specifica temperatura richiesta dagli alimenti in essa introdotti. Refrigerated cabinets the internal compartment of which is divided into two or more cells in which different temperatures are produced, each suitable for the preservation of a specific type of food, are widely known in the state of the art. Generally, these refrigeration cabinets are equipped with separate refrigerating circuits which are sized to ensure the maintenance of the specific temperature required by the food introduced in the respective cell.
Sono noti anche armadi frigoriferi con più celle ma provvisti di un unico circuito refrigerante che viene controllato tramite distinte sonde, sistemate in ciascuna cella. In questo caso, la circolazione del fluido refrigerante viene opportunamente indirizzata e/o parzi alizzata, mediante dispositivi valvolari, in modo da assicurare la corretta refrigerazione delle diverse celle in funzione delle rispettive condizioni di temperatura. Refrigeration cabinets with several cells are also known but provided with a single refrigerant circuit which is controlled by means of separate probes, arranged in each cell. In this case, the circulation of the refrigerant fluid is suitably directed and / or partially controlled, by means of valve devices, so as to ensure the correct refrigeration of the various cells according to the respective temperature conditions.
Gli armadi frigoriferi noti non risolvono però il problema che si presenta quando occorre conservare, sostanzialmente alla medesima temperatura, alimenti di tipo diverso dal punto di vista delle qualità organolettiche. In particolare, il problema riguarda la conservazione di alimenti come carni, formaggi, verdure e simili, ciascuno dei quali emana uno specifico odore che può mescolarsi con quello degli altri alimenti, se conservati in una medesima cella, col risultato di alterare il gusto degli alimenti in misura inaccettabile. Known refrigeration cabinets, however, do not solve the problem which arises when it is necessary to preserve, substantially at the same temperature, foods of a different type from the point of view of organoleptic qualities. In particular, the problem concerns the conservation of foods such as meats, cheeses, vegetables and the like, each of which gives off a specific odor that can mix with that of other foods, if stored in the same cell, with the result of altering the taste of the food. to an unacceptable extent.
La soluzione di utilizzare armadi frigoriferi dotati di una molteplicità di celle separate, ciascuna raffreddata mediante un proprio circuito frigorifero, è improponibile sia per motivi economici sia per la complessità tecnica di realizzazione, tenendo conto che nelle diverse celle occorre mantenere praticamente la medesima temperatura. The solution of using refrigeration cabinets equipped with a plurality of separate cells, each cooled by its own refrigeration circuit, is impractical both for economic reasons and for the technical complexity of construction, taking into account that in the different cells it is necessary to maintain practically the same temperature.
Il presente trovato propone di realizzare un armadio frigorifero dotato di almeno due celle separate, in ciascuna delle quali è alloggiato un evaporatore facente parte di un unico circuito frigorifero atto a realizzare nelle celle sostanzialmente la medesima temperatura. La caratteristica innovativa del trovato consiste essenzialmente nel fatto che per la separazione delle celle si utilizza una parete in materiale avente un elevato coefficiente di trasmissione termica e in tale parete è inserita una sonda termostatica che controlla il funzionamento del circuito frigorifero. The present invention proposes to provide a refrigeration cabinet equipped with at least two separate cells, in each of which an evaporator is housed which is part of a single refrigeration circuit able to produce substantially the same temperature in the cells. The innovative feature of the invention essentially consists in the fact that for the separation of the cells a wall made of material having a high thermal transmission coefficient is used and a thermostatic probe is inserted in this wall which controls the operation of the refrigeration circuit.
Questa e altre caratteristiche del trovato sono definite nelle rivendicazioni che concludono il presente brevetto. This and other characteristics of the invention are defined in the claims which conclude the present patent.
Il trovato viene in seguito descritto, a titolo esemplificativo e non limitativo, con riferimento al disegno allegato, che mostra schematicamente in prospettiva un armadio frigorifero secondo il trovato, in condizione aperta e con un particolare costruttivo ingrandito ed evidenziato separatamente. The invention is hereinafter described, by way of non-limiting example, with reference to the attached drawing, which schematically shows in perspective a refrigerated cabinet according to the invention, in an open condition and with a construction detail enlarged and highlighted separately.
L’armadio frigorifero secondo il trovato è complessivamente costituito da un mobile 10 dotato di due scomparti interni, o celle 11, 12, che sono completamente separati tra loro e che sono chiusi da rispettive porte 13, 14. All’intemo degli scompartì possono essere inserite, in modo noto e non mostrato nel disegno, griglie o ripiani per il supporto di alimenti diversi, che richiedono comunque di essere conservati a temperature sostanzialmente uguali. The refrigerator cabinet according to the invention is constituted as a whole by a piece of furniture 10 equipped with two internal compartments, or cells 11, 12, which are completely separated from each other and which are closed by respective doors 13, 14. Inside the compartments can be inserted, in a known way and not shown in the drawing, grids or shelves for supporting different foods, which in any case require to be kept at substantially the same temperatures.
In ciascuna cella 11, 12 è alloggiata una rispettiva batteria evaporante ventilata 15, 16, dette batterie evaporanti essendo normalmente collegate in serie in un circuito refrigerante che comprende un compressore 17 e un condensatore 18. Vantaggiosamente, come mostrato in figura, i componenti del circuito refrigerante sono alloggiati nella parte superiore del mobile. A respective ventilated evaporating coil 15, 16 is housed in each cell 11, 12, said evaporating coils being normally connected in series in a refrigerant circuit which includes a compressor 17 and a condenser 18. Advantageously, as shown in the figure, the components of the circuit coolant are housed in the upper part of the cabinet.
Secondo il trovato, le celle 11, 12 sono separate da una parete 20 all’intemo del mobile 10, detta parete essendo realizzata in modo da consentire il massimo scambio termico fra le due celle ma nessuna miscelazione dei flussi di aria refrigerata che circolano nelle medesime. In altre parole, la parete 20 costituisce una chiusura a tenuta di aria fra le due celle. La parete 20 è preferibilmente realizzata sotto forma di un foglio metallico o una lamiera molto sottile, quindi con un materiale ad elevata conducibilità termica. In questo modo si assicura un rapido raggiungimento dell’ equilibratura delle temperature nelle celle, anche quando soltanto ima di esse viene raffreddata per esigenze operative, ad esempio quando si introduce un nuovo carico di alimenti da raffreddare. According to the invention, the cells 11, 12 are separated by a wall 20 inside the cabinet 10, said wall being made in such a way as to allow maximum heat exchange between the two cells but no mixing of the flows of refrigerated air circulating therein. . In other words, the wall 20 forms an airtight seal between the two cells. The wall 20 is preferably made in the form of a metal sheet or a very thin sheet, therefore with a material with high thermal conductivity. This ensures rapid achievement of temperature balance in the cells, even when only one of them is cooled for operational needs, for example when introducing a new load of food to be cooled.
Ancora secondo il trovato, un’unica sonda termostatica 21 è prevista per controllare il funzionamento del circuito frigorifero. La sonda 21 deve sentire la temperatura in entrambe le celle 11 , 12 e, pertanto, essa viene installata nella parete divisoria 20. Per semplicità costruttiva, la sonda 21 (come mostrato schematicamente in vista e in sezione, nella porzione ingrandita ed evidenziata della figura) viene disposta in un’apertura praticata nella parete 20 e chiusa ermeticamente fra due gusci fissati sulle superfici opposte della parete stessa. 1 gusci possono essere fissati in qualsiasi modo noto, ad esempio per incollamento o saldatura. In questo modo, la sonda 21 normalmente rileva una temperatura che è la media fra le temperature delle celle 11, 12. Inoltre, essa rileva immediatamente una repentina variazione di temperatura in una delle celle 11, 12, mettendo conseguentemente in funzionamento il circuito frigorifero. Still according to the invention, a single thermostatic probe 21 is provided to control the operation of the refrigeration circuit. The probe 21 must sense the temperature in both cells 11, 12 and, therefore, it is installed in the dividing wall 20. For constructive simplicity, the probe 21 (as shown schematically in view and in section, in the enlarged and highlighted portion of the figure ) is arranged in an opening made in the wall 20 and hermetically closed between two shells fixed on the opposite surfaces of the wall itself. The shells can be fixed in any known way, for example by gluing or welding. In this way, the probe 21 normally detects a temperature which is the average between the temperatures of the cells 11, 12. Furthermore, it immediately detects a sudden temperature variation in one of the cells 11, 12, consequently putting the refrigeration circuit into operation.
Naturalmente la sonda 21 è collegata al compressore 17 del circuito frigorifero tramite un circuito elettronico di tipo noto e qui non descritto, che consente l’impostazione e il controllo della temperatura richiesta nelle celle dell’armadio frigorifero. Of course, the probe 21 is connected to the compressor 17 of the refrigeration circuit through an electronic circuit of a known type and not described here, which allows the setting and control of the temperature required in the refrigeration cabinet cells.
Pertanto, la soluzione proposta nel presente brevetto è particolarmente semplice e comoda. Essa consente di realizzare un armadio frigorifero con un unico circuito refrigerante e almeno due celle separate nelle quali possono essere conservati alimenti che richiedono temperature di conservazione sostanzialmente uguali, ma che non possono essere tenuti in uno stesso ambiente per motivi di ordine organolettico. Modifiche e varianti dell’ armadio frigorifero descritto possono essere previste senza uscire dall’ambito del medesimo concetto innovativo. Therefore, the solution proposed in the present patent is particularly simple and convenient. It makes it possible to create a refrigeration cabinet with a single refrigerant circuit and at least two separate cells in which foods which require substantially the same storage temperatures, but which cannot be kept in the same environment for organoleptic reasons, can be stored. Changes and variants of the refrigerated cabinet described can be envisaged without departing from the scope of the same innovative concept.
