Definitions
- the present invention relates to a fume-exhausting apparatus, in particular for chimneys and fireplaces, having the features recited in the preamble of claim 1.
- the document FR-A- 2 467 358 which is herein referred as the most relevant state of the art, teaches to provide, in a chimney comprising a hearth and a hood for collecting fumes to be sent to a flue, a number of channels having lower openings directed downwardly close to the lower inlet mouth of the hood and upper openings directed upwardly and communicating with the lower end of the flue.
- An air stream is drived around the conveying channel and blown into the room, in such a manner to provide a heat recovering from the fumes.
- US Patent n. 4,100,913 teches to provide conveying channels extending from the upper portion of the hood and entering the lower end of the flue. Also in this document the conveying channels are arranged for providing a heat receiving by an air stream passing around the channels itselves.
- US Patent n. 2,277,381 teaches to provide conveying channels extending from the upper portion of the hood and arranged for providing a heat receiving from the fumes, by an air stream blow around the channels itselves.
- the technical task underlying the present invention is to provide a fume-exhausting apparatus, in particular for chimneys and fireplaces, capable of substantially eliminating the above drawbacks.
- the fume-exhausting apparatus according to the invention has been generally identified by reference numeral 1.
- the apparatus 1 is adapted to be fitted in a chimney or fireplace of a conventional type known per se comprising a hearth 2, a hood 3 for collecting the fumes produced on the heart, and a flue 4. It comprises a plurality of channels 5 for conveying fumes, located above the hearth 2 and therefore extending within the hood 3.
- the conveying channels 5 exhibit lower openings 5a directed downwardly, disposed close to, or at all events communicating with, the lower inlet mouth 3a of the hood 3, and upper openings 5b directed upwardly and disposed close to a lower end 4a of the flue 4, so that they are affected by a draught effect created thereinto.
- the transverse section of the conveying channels 5 has an area corresponding at least to the area of the transverse section of the flue and preferably greater than the latter by 50%.
- the conveying channels 5, for example defined by lengths of rectilinear pipes having a circular section, are disposed in mutual side by side relation to form a bundle and converge close to the upper portion 3b of the hood 3, so that they substantially occupy, at least close to the upper openings thereof 5b, the whole transverse section of the hood 3, apart from the gaps present between the pipes as a result of their circular section.
- one main conveying channel or pipe 5c is provided which is disposed centrally substantially above the flame present in the hearth 2, as well as a plurality of auxiliary conveying channels or pipes 5d disposed perimetrically and each of them having a transverse section the area of which is lower than that of the trasverse section of the main pipe 5c.
- an upper plate-like closing element 6b is also provided which is disposed close to the upper portion 3b of the hood 3.
- the upper plate-like element 6b is also provided with through holes adapted to sealingly engage the upper end portions of the conveying channels 5.
- Suitable air intakes 7 formed in the hood 3 for admitting cold air from the surrounding atmosphere and emitting hot air thereinto enable a forced air circulation to be created, optionally with the aid of ventilation means, which air passing through the gaps present between the conveying channels 5 can be heated by the heat transmitted from the fumes.
- the conveying channels 5 are disposed in mutual side by side relation and in alignment with each other and they occupy the hood volume, and therefore the transverse hood section, only partially.
- the conveying channels 5 in this embodiment exhibit their lower openings 5a disposed in alignment along the front side of the lower inlet mouth 3a of the hood 3, or anyhow consecutively aligned substantially parallely to said front side, so as to define a suction area extending along the whole extension of said side.
- the conveying channels 5 are integral with each other and consist of a unitary body 8, being divided by partitions 8a.
- Such unitary body 8 can be easily engaged within an already installed hood in order to improve performance of same in drawing fumes.
- the upper openings 5b of the conveying channels 5 defined by the partitions 8a open into an interconnecting pipeline 9 at differentiated heights in order not to hinder the respective smoke flows.
- the upper ends 5b of the conveying channels 5 located at the laterally opposite ends of the unitary body 8 communicate with the upper portion of the interconnecting pipeline 9 by two tubular headers 20 exhibiting end portions 20a adapted to be laterally fitted in the interconnecting pipeline as they bend according to the progress direction of the fumes along said pipeline.
- a draught duct 10 connected in succession to the interconnecting pipeline 9 is a draught duct 10 having an extension enabling one upper end thereof 10a to be directly located in the flue 4 In this manner, close to the upper end 10a there is a negative pressure created by the quick flowing of the fumes from the hood 3, which negative pressure greatly increases the suction effect of the conveying channels 5.
- the conveying channels 5 enable the whole fume flow to be divided into partial flows, each of which exhibits a reduced vorticity and greater upward kinetic energy.
- the apparatus in question enables the so-called draught effect created within the flue to be moved much closer to the flame or, in other words, to the real fume-producing area, thereby enabling said fumes to be drawn upwardly in a stronger manner.
- the results of said draught effect have been practically zero at distances ranging between 20 and 30 cm from the lower end of the flue itself.
- a suction area extending along the front edge of the hearth is created so as to form a barrier against the emission of fumes towards the room where the fireplace is located.
- the apparatus of the invention makes it possible to intervene on already installed fireplaces with ease, because the apparatus can be readily fitted into a hood and engaged to the front wall thereof. Therefore the apparatus of the invention is capable of making a fireplace flue work properly even if it has an inefficient draught as a result of an imperfect design and/or construction, or at all events is capable of improving performace of a fireplace even under the most unfavourable circumstances.
