Controlled air intake system for chimneys

Abstract

The invention relates to a controlled air intake system for chimneys, in chimneys that have a lower fireplace and an upper outlet on which a cowl (4) with a series of perimeter slats (41, 42) is disposed. The cowl (4) is divided into an upper part (43) communicated with the fireplace by means of a conduit (1), and a lower part (44) that is separate from the upper part (43) and communicated with the air intake into the fireplace by means of a space (3) running along the length of the chimney.

[0001] DESCRIPTION

[0002] Controlled air intake system for chimneys

[0003] OBJECT OF THE INVENTION

[0004] The invention, as the title of this specification indicates, is a controlled air intake system for chimneys. It is an innovation that offers advantages previously unknown within current techniques.

[0005] TECHNICAL SECTOR

[0006] The present invention falls within the sector of everyday needs, especially in furniture, articles or appliances for domestic use, coffee grinders, spice grinders, vacuum cleaners in general, in the classification of devices for ventilation, cooling or heating.

[0007] It also falls within the mechanical and lighting sector, especially in heating, armament, blasting, in the classification of combustion apparatus, combustion processes, supply of air or non-combustible liquids or gases to combustion apparatus in general.

[0008] Likewise, in valves or draft regulators specially adapted to the control of air supply or draft in combustion appliances, specifically in induced draft in combustion appliances, chimney caps or vents, terminals for flue pipes.

[0009] STATE OF THE ART

[0010] The present invention arises as an improvement to traditional methods of the air system for chimneys.

[0011] This is because some types of chimney caps may not be suitable for certain types of chimneys, which can limit their effectiveness in facilitating the controlled intake of outside air. It also aims to simplify the installation process, offering a solution that streamlines and speeds up the installation of air intake systems for chimneys that require them.

[0012] Consequently, this invention provides a controlled air intake system for chimneys that allows for a regulated and constant flow of outside air, as well as easy, simple and optimized installation.

[0013] Currently, there is no known controlled air intake system for chimneys that has structural and constitutive technical characteristics equal or similar to those described in this descriptive report, as claimed.

[0014] DESCRIPTION OF THE INVENTION

[0015] The object of the present invention is the creation of a controlled air intake system for chimneys that provides a notable innovation within its field of application in the current state of the art, the characterizing details that make it possible being conveniently included in the final claims that accompany this description.

[0016] This innovation ensures that the chimney receives the proper airflow to maintain efficient combustion, reducing the buildup of soot and other residues, which in turn decreases the need for frequent cleaning and prolongs the chimney's lifespan.

[0017] The controlled air intake system for chimneys is designed for installation in chimneys with a hearth, combustion boiler, burner, etc. (hereafter referred to as the "hearth") and an upper outlet where a cap with a series of perimeter louvers is located. The cap is divided into an upper part connected to the hearth by a duct and a lower part, independent of the upper part, connected to the hearth air intake by a space along the chimney.

[0018] This system is particularly beneficial in areas with limited natural airflow and in urban environments, where tall buildings and other obstacles can impede air intake. The system's design also simplifies cleaning, even allowing for chimney cleaning by drone. The drone removes the top section, and a roller and air jet are used to clean it. The drone can also capture videos and photos to assess the condition of the flues and chimney.

[0019] The system's design also prevents water and wind from entering the duct. The venturi system design helps fumes escape more quickly. It is also designed so that if birds enter the chimney cap, they will encounter a front plate that prevents them from entering the duct and simultaneously facilitates their exit to the outside.

[0020] EXPLANATION OF THE FIGURES

[0021] To complete the description being made and in order to help in the better understanding of the characteristics of the invention, this descriptive report is accompanied, as an integral part thereof, by some figures in which, for illustrative and non-limiting purposes, the following has been represented.

[0022] Figure 1 shows a perspective view of the controlled air inlet system for chimneys, detailing the chimney cap that incorporates a first blade.

[0023] Figure 2 shows a perspective view of the threaded rod used by the chimney cap of the controlled air intake system for chimneys.

[0024] PREFERRED EMBODIMENT OF THE INVENTION.

[0025] This invention consists of a controlled air intake system for chimneys, characterized by comprising an internal duct (1) that connects a hearth or burner to the upper outlet of the chimney. The duct (1) is arranged along the length of the chimney, leaving a space (3) for the passage of air from the top to the air inlet of the hearth. In the embodiment shown, the space (3) is annular.

[0026] The top of the chimney has a cap (4), which contains a series of perimeter louvers (41, 42) that connect the inside of the cap (4) to the outside. These louvers allow smoke and air to escape and prevent water from entering the chimney and hearth. The inside of the cap (4) is divided into two separate parts: an upper part (43) connected to the flue (1) and the outside by the upper louvers (41), and a lower part (44) connected to the space (3) and the outside by the lower louvers (42). The number of louvers (41, 42) in each part varies, generally having more upper louvers (41) than lower louvers (42). The flue (1) preferably reaches a midpoint in the upper part (43) to ensure that the resulting Venturi helps draw in the smoke.

[0027] In operation, the smoke exits the firebox (3) through the flue (1) to the chimney cap (4), from where it exits through the upper baffles (41). Simultaneously, outside air, drawn in by the wind, enters the lower section (44) and descends through the space (3) to feed the firebox. The airflow along the chimney also serves to preheat the air, as it is in contact with the flue (1), thus making combustion in the firebox (3) more efficient.

[0028] The lower louvers (42) and the space (3) provide a controlled intake of outside air for chimneys that require air intake. The louvers (41, 42) can be oriented, for example by means of a threaded rod that passes through them, the louvers (41, 42) being articulated so that the movement of the threaded rod produces their rotation and reorientation, in a manner similar to an Archimedes screw.

[0029] The cap (4) can be attached to the chimney by any suitable method.

[0030] Having sufficiently described the nature of the present invention, as well as the manner of putting it into practice, it is not considered necessary to make its explanation more extensive so that any expert in the field may understand its scope and the advantages that derive from it, it being noted that, within its essentiality, it may be put into practice in other modes of embodiment that differ in detail from the one indicated as an example, and which will also achieve the protection sought provided that its fundamental principle is not altered, changed or modified.
