Description

Extractor with fume treatment system using nebulization OBJECT OF THE INVENTION The invention, as the title of this descriptive document states, is an extractor with a fume treatment system using water nebulization, and is therefore applicable to all types of kitchens, stoves, and equipment where fumes are produced. It is an innovation that, within current technologies, offers advantages previously unknown. TECHNICAL SECTOR The present invention falls within the sector corresponding to various industrial techniques and transport, in the subclass of physical or chemical procedures or apparatus in general, especially in filters or procedures specially modified for the separation of particles dispersed in gases or vapors, as well as in the section of purifying filters. Similarly, the present invention falls within the sector of mechanics, lighting, heating, armament and blasting, in the subclass of heating, stoves and ventilation, specifically in the section that corresponds to the elimination of cooking fumes. STATE OF THE ART The present invention arises from observing that numerous restaurants, inns, gastronomic establishments and also homes that use grills or wood or charcoal stoves face serious limitations derived from the generation of smoke, grease and odors during cooking. In urban and residential environments, these emissions are not only annoying and harmful to health, but also contravene increasingly strict environmental regulations, restricting the use of this equipment indoors or in populated areas. This situation means that many establishments, even those with facilities of great culinary and traditional value, are forced to limit their activity or even cease operations due to non-compliance with regulations or complaints from neighbors. In the home, the same problems affect air quality, permeate spaces, and generate conflicts due to persistent discomfort. Added to this are the fire risks stemming from the accumulation of grease and sparks, as well as the high maintenance and cleaning costs associated with conventional extractor systems. A similar problem occurs with stoves, especially those that burn wood or coal. These stoves generate a large amount of smoke, sometimes with sparks, which affects the air quality of the surrounding area. Accordingly, the present invention provides an extractor with a fume treatment system by nebulization that allows the continued use of traditional grills and stoves, among other equipment, in both domestic and professional environments, eliminating smoke and polluting particles, reducing risks and guaranteeing a clean, safe experience that is fully compliant with current regulatory requirements. Currently, there is no known existence of any extractor with a fume treatment system using nebulization that presents structural and constitutive technical characteristics equal or similar to those described in this descriptive report, as claimed. DESCRIPTION OF THE INVENTION The object of the present invention is the creation of an extractor with a fume treatment system by nebulization 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. The present invention relates to an extractor with a smoke treatment system by nebulization that can be implemented in several constructive versions, including a rear version, behind the grill, stove or other equipment, a side version on one side of the equipment, a lower version, each designed to integrate efficiently into different cooking environments, optimizing the capture and treatment of smoke and ensuring safe operation in accordance with environmental and operational requirements. This invention eliminates the problems associated with the generation of smoke, odors, and polluting particles in cooking environments, both commercial and domestic, through an effective treatment that allows the continued safe use of traditional grills and stoves in compliance with current regulations. Its operation ensures the reduction of harmful emissions and the prevention of risks arising from the accumulation of grease and sparks, overcoming the usual limitations of conventional systems. This innovation is especially useful for restaurants, taverns, eateries, and homes, allowing them to enjoy the experience of real fire without the hassle or risks. Furthermore, it helps improve air quality, reduce maintenance costs, minimize conflicts with neighbors, and ensure a clean, safe, and comfortable cooking experience for users. The invention comprises one or more intake fans that draw smoke and other gases into a flue leading to a misting system located downstream of the intake fans. This misting system includes a chamber containing several nozzles that mist the fluid, typically water. The smoke from the intake fans passes through the chamber to an outlet fan. The chamber has a water outlet at the bottom that directs the water to a reservoir, from which it is drawn back to the nozzles. This water circuit may require one or more pumps, which may be submerged in the reservoir. The reservoir has an inlet valve to replenish any lost water, for example, with a float system for automatic opening. The reservoir may also have a drain valve. In another embodiment, the misted water is discharged directly from the bottom of the chamber.The water may contain additives, such as soap, to prevent captured oils and grease from clogging the water circuit. The tank may have a top lid for inspection and maintenance. The extractor has different filters: particle filters, smoke filters, and oil condensation filters. In one embodiment, the extractor comprises an air curtain circuit, consisting of one or more compressors with one or more air intakes, and a linear air outlet at the front, on one or both sides. The air exits with sufficient pressure to create a "wall" that impedes the passage of fumes. These air curtains help contain the smoke above the smoke generation area (fireplace, grill) and ensure that all the smoke is captured by the extractor. The suction fan can be axial, vane-type, or have adjustable speed. It is planned to incorporate a smoke outlet grille located after the smoke filter, intended to regulate the flow of treated air to the outside, contributing to better ventilation control and treatment efficiency. The flue may include a cooling chamber, in which a heat exchanger is located, for example, with water circulating in the wall. This water may be from the misting water circuit itself, or from an auxiliary circuit with its own pump and a heat dissipation zone (external radiator). Any part of the extractor (smoke duct, mist chamber, tank) can have access points for maintenance. The stove may include an air inlet regulator to control the flow of fresh air into the combustion chamber, an air inlet grille, refractory bricks on the inner walls of the chamber, and a CO outlet pipe, all aimed at optimizing combustion and gas evacuation, ensuring the efficiency and safety of the system. For the assembly of the smoke duct and the other parts of the extractor, modules can be defined that are coupled, one on top of the other, by means of guides, rails or similar arranged in their contact and support areas. The extractor may include a hood contributing to the initial capture of fumes and their direction towards the treatment systems. Finally, all construction versions can include an electrical panel configured to control and protect the equipment's electrical components, comprising buttons and switches for system operation, thus enabling centralized and safe control of the overall operation of the unit. This panel will be thermally insulated from the flue and other high-temperature areas. To use the extractor with a misting system, the user must place it above the grill, fireplace, or other areas where smoke, vapors, and gases are produced, and connect it to the water and power supply. Then, the user must activate the extraction and misting systems, adjusting the controls according to the cooking conditions and the level of smoke generated. Different programs can be defined depending on the type of smoke produced, so that cooking pasta does not require as much misting as grilling. The system will automatically treat smoke and polluting particles, reducing odors and improving air quality in the surrounding area. Furthermore, the user can monitor its operation through available access points, logs, and controls, facilitating maintenance and ensuring safe and efficient use of the equipment at all times.

PREFERRED EMBODIMENT OF THE INVENTION The extractor with a misting system is applicable to stoves, cooking appliances, and other equipment that generates fumes or other gases during combustion and evaporation. It is available in several configurations, including a rear version (Figures 1 and 2), a side version (Figures 3 and 4), a bottom version (Figures 5 and 6), and a version specifically for stoves. Each version is designed to adapt to different fume generation configurations, while maintaining a functional structure that allows for the capture, treatment, and controlled expulsion of the fumes generated during combustion or cooking. In all versions, the extractor comprises a flue (1) with one or more intake fans (2), which directs the aspirated air, containing fumes, vapors, and gases, to a misting chamber (3), generally located at a lower point. This chamber (3) has misting nozzles (4) connected to a tank (5) and a pump (6), usually submerged. The nozzles (4) atomize the liquid, generally water, in the chamber (3), where it mixes with and captures the fumes, vapors, and other substances in the air. The liquid falls to the bottom of the chamber (3), where there is a drain (7) that can lead to a discharge point, back to the tank (5), etc. For example, some of the water can be discarded and some returned to the tank (5), where it is replenished from the mains or another point by means of a float valve (8). The tank (5) has a removable lid (51) for inspection and maintenance, which may have a viewing window or transparent area to allow for quick visual inspections. Ideally, it also has a drain valve (52) and a water filter (53) at the pump inlet (6). The chamber (3) terminates in one or more exhaust fans (9), from which the clean air can be directed to a chimney or any other suitable point. This air is odorless, contains no sparks or embers, and does not affect the neighbors. The extractor has ten different types of filters to condense oils and greases and to retain particles, as is common in other extractors. It may also have a hood. The extractor has access panels (11) to allow for cleaning and maintenance. An electrical control panel, protected against heat and smoke, can be installed in one of the access panels (11). One embodiment comprises one or more air curtain circuits (13), consisting of one or more compressors, each with its own outside air intake and a line-shaped air outlet near the fume production area. These air outlets are arranged at the front or sides to prevent the easy passage of smoke, gases, or sparks through that area. This creates a strong, essentially flat airflow, referred to in the art as an "air curtain" (13). This airflow ensures that the user is not affected by fumes, sparks, or gases, and that all of them are captured by the extraction fans (2). Stoves typically consist of a door with a frame and gasket designed to hermetically seal the combustion chamber, so they don't usually require air curtains. The door and walls already prevent gas leaks and maintain the negative pressure inside. In one embodiment, a cooling chamber (14) is provided, which may have a heat exchanger, for example, with water circulation in the wall. This water may be from the nebulization water circuit itself, or from an auxiliary circuit with its own pump and a heat dissipation zone. The heat sink may be a radiator located outside the installation, or at the air intake to the combustion zone. This auxiliary circuit may require an auxiliary tank. The extractor may consist of a series of modules that can be detached from each other. It would start with a structural module (15) with guides (151), for example telescopic, configured to allow the movement, extraction, maintenance or replacement of the other components. 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.
