Description

Stufa a pellet Pellet stove

Campo tecnico dell’invenzione Technical field of invention

La presente invenzione concerne una stufa a pellet, in particolare per riscaldamento domestico, con il focolare separato da due setti laterali posti tra la superficie anteriore e la superficie posteriore della stufa e un setto di base e al meno un fascio tubiero separato dal focolare da almeno un setto laterale, posto orizzontalmente e in direzione parallela allo stesso setto laterale. The present invention relates to a pellet stove, in particular for domestic heating, with the hearth separated by two lateral baffles placed between the front surface and the rear surface of the stove and a base baffle and at least a tube bundle separated from the hearth by at least a lateral septum, placed horizontally and in a direction parallel to the same lateral septum.

Stato dell’arte State of the art

Le stufe a pellet per riscaldamento domestico attualmente sul mercato, per sfruttare il calore contenuto nei fumi della combustione presentano uno scambiatore di calore a fascio tubiero disposto sopra il focolare e con i tubi paralleli alla faccia frontale della stufa. Una stufa di questo tipo à ̈ descritta nel brevetto US-B-5873356. Tale stufa presenta un notevole ingombro verticale e inoltre i tubi del fascio tubiero per essere puliti richiedono l’intervento di un tecnico che deve smontare la parte anteriore e, manualmente deve pulire i tubi uno ad uno. In order to exploit the heat contained in the combustion fumes, the pellet stoves for domestic heating currently on the market have a tube bundle heat exchanger arranged above the hearth and with the pipes parallel to the front face of the stove. A stove of this type is described in US-B-5873356. This stove has a considerable vertical dimension and furthermore the tubes of the tube bundle to be cleaned require the intervention of a technician who must disassemble the front part and manually clean the tubes one by one.

SOMMARIO DELL’INVENZIONE SUMMARY OF THE INVENTION

La presente invenzione permette di superare questi svantaggi e inconvenienti che si trovano nelle stufe attualmente sul mercato, consentendo di costruire una stufa a pellet di altezza contenuta, con uno scambiatore a fascio tubiero ad alto rendimento e con un sistema di pulizia facile ed efficace. The present invention allows to overcome these disadvantages and drawbacks that are found in stoves currently on the market, allowing the construction of a pellet stove of limited height, with a high efficiency shell and tube exchanger and with an easy and effective cleaning system.

L’obbiettivo à ̈ raggiunto con una stufa a pellet caratterizzata dal fatto che il focolare di detta stufa presenta due setti laterali posti tra la superficie anteriore e la superficie posteriore della stufa e un setto orizzontale posto sopra o sotto il focolare e almeno un fascio tubiero separato dal focolare da almeno un setto laterale, detto fascio tubiero à ̈ disposto orizzontalmente e in direzione parallela allo stesso setto laterale. The objective is achieved with a pellet stove characterized by the fact that the hearth of said stove has two side baffles placed between the front surface and the rear surface of the stove and a horizontal baffle placed above or below the hearth and at least one beam tube separated from the furnace by at least one lateral partition, said tube bundle is arranged horizontally and in a direction parallel to the same lateral partition.

Altra caratteristica à ̈ data dal fatto che i fasci tubieri sono due. Another feature is given by the fact that the tube bundles are two.

Altra caratteristica à ̈ data dal fatto che ogni fascio tubiero à ̈ dotato di una piastra che può essere azionata dall’esterno scorrendo su tutta la lunghezza del fascio tubiero per pulire la superficie dello stesso. Another feature is given by the fact that each tube bundle is equipped with a plate that can be operated from the outside by sliding along the entire length of the tube bundle to clean its surface.

Altre caratteristiche e vantaggi dell'invenzione appariranno chiari dalla descrizione, qui appresso, di un modo di realizzazione dato a titolo d'esempio non limitativo dalla figura 1. Other characteristics and advantages of the invention will become clear from the description, hereinafter, of an embodiment given by way of non-limiting example in Figure 1.

Descrizione sintetica della figura Brief description of the figure

La figura 1 mostra una rappresentazione assonometrica di un dispositivo di pulizia per griglia di un focolare di una stufa a pellet oggetto della presente invenzione. Figure 1 shows an axonometric representation of a grate cleaning device of a hearth of a pellet stove object of the present invention.

DESCRIZIONE DETTAGLIATA DELLE FIGURA DETAILED DESCRIPTION OF THE FIGURES

Con riferimento alla figura 1, la stufa a pellet 1 Ã ̈ costituita da un focolare 2 che presenta due setti laterali 3, posti tra la superficie anteriore e la superficie posteriore della stufa, ed un setto orizzontale 4, posto sotto o sopra il focolare 2. Fasci tubieri 5 sono disposti orizzontalmente e paralleli alla superficie dei setti laterali 3. Una ventola di estrazione 6 Ã ̈ posta sotto o sopra il focolare della stufa 2 in modo da costringere i fumi della combustione prodotti nel focolare 2 a risalire i setti 3, ad attraversare i fasci tubieri 5 e ad essere evacuati attraverso una canna fumaria. With reference to figure 1, the pellet stove 1 consists of a hearth 2 which has two side baffles 3, placed between the front surface and the rear surface of the stove, and a horizontal baffle 4, placed under or above the hearth 2 . Tube bundles 5 are arranged horizontally and parallel to the surface of the side partitions 3. An extraction fan 6 is placed under or above the hearth of the stove 2 so as to force the combustion fumes produced in the hearth 2 to rise up the partitions 3, to cross the tube bundles 5 and to be evacuated through a flue.

I fasci tubieri 5 disposti ai lati dei setti 3 orizzontalmente posti tra la superficie anteriore e la superficie posteriore della stufa possiedono una piastra forata che può essere tirata avanti e indietro dall’esterno e che scorre sui tubi raschiandoli, pulendoli e contribuendo a mantenerli puliti in modo da aumentare l’efficienza della stufa e facilitando la manutenzione della stessa. The tube bundles 5 arranged on the sides of the baffles 3 horizontally placed between the front surface and the rear surface of the stove have a perforated plate which can be pulled back and forth from the outside and which slides on the tubes scraping them, cleaning them and helping to keep them clean in order to increase the efficiency of the stove and facilitate its maintenance.

In una forma di realizzazione preferita la ventola di estrazione 6 à ̈ posta sotto il focolare 2, ma à ̈ possibile posizionare la ventola di estrazione 6 sopra il focolare 2 ottenendo gli stessi vantaggi e facendo fare un percorso più lungo con due setti. In a preferred embodiment the extraction fan 6 is placed under the firebox 2, but it is possible to position the extraction fan 6 above the firebox 2 obtaining the same advantages and making a longer path with two baffles.

La disposizione dei fasci tubieri 5 ai lati del focolare 2 consente di ridurre l’altezza della stufa e di aumentare l’efficienza della stessa stufa . The arrangement of the tube bundles 5 on the sides of the firebox 2 allows to reduce the height of the stove and to increase the efficiency of the stove itself.

Il trovato, bene inteso, non si limita alla rappresentazione data dalla tavola, ma può ricevere perfezionamenti e modifiche dall'uomo del mestiere senza uscire peraltro dal quadro del brevetto. The invention, well understood, is not limited to the representation given by the table, but can receive improvements and modifications by the man of the trade without leaving the framework of the patent.

La presente invenzione consente numerosi vantaggi e di superare difficoltà che non potevano essere vinte con i sistemi attualmente in commercio. The present invention allows numerous advantages and to overcome difficulties that could not be overcome with the systems currently on the market.
