Description

Title of the invention: Adjustable air extraction vent for room ventilation, equipped with a removable mounting system. Technical field

[0001] The invention relates to an air extraction vent for the ventilation of a room. Technological background

[0002] Indoor ventilation is crucial for maintaining a healthy environment by regulating air quality, minimizing humidity levels, and eliminating pollutants. Exhaust vents play an essential role in these ventilation systems by enabling the efficient removal of stale air to the outside, such as extracting unwanted gases, fumes, or odors. Traditionally, these vents are connected to ventilation units or other building ventilation equipment via ductwork. They are installed in openings in a surface, whether a ceiling or a wall.

[0003] Over the years, various innovations have been introduced to improve the performance, energy efficiency, and aesthetics of extraction vents.

[0004] Ventilation inlets, such as the one described in European patent EP1541933, are known to include ventilation valves adjustable by actuators, sensors, and a control system to regulate the extracted airflow according to physical parameters such as light, humidity, pressure, temperature, and / or air velocity. However, these inlets, like the one described in European patent EP1541933, have bodies that protrude from the surface of the wall openings, providing exposure for the accumulation of dust, debris, and the penetration of insects or pests. This dust, lint, and other small debris, particularly that left by insects or pests, can accumulate on the grilles and inside the air extraction ducts. This accumulation can reduce the airflow, thus decreasing the ventilation efficiency.Furthermore, the fact that they protrude from the surface of the wall openings is unsightly and limits furniture placement options to avoid obstructing a door or cupboard. Finally, these vents lack any easy, tool-free way to be removed from the wall openings.

[0005] International patent application WO2022243351 is known, proposing a ventilation outlet that includes a manual flow adjustment mechanism to control the airflow through the outlet. To improve aesthetics and limit To prevent dust accumulation, it features a cover to improve the user's visibility and sits flush with the wall opening. However, this vent lacks a simple, tool-free way to remove itself from the wall openings. Furthermore, this design does not prevent the growth of mold and bacteria, nor does it prevent grease buildup. Indeed, in humid environments such as bathrooms or kitchens, moisture can accumulate in exhaust vents and ducts, promoting the growth of mold and bacteria. This can not only clog the exhaust vents but also pose risks to indoor air quality and health. Similarly, grease and oil vapors can accumulate on exhaust vents, forming a sticky layer that can be difficult to clean and may even be flammable.

[0006] For these reasons, it is important to regularly clean the air extraction vents to ensure efficient ventilation, maintain good indoor air quality or prevent damage to the ventilation system.

[0007] There is therefore a need for extraction vents that regulate airflow, are more aesthetically pleasing, and easier to clean in order to improve their long-term performance. In particular, they must allow for easy removal of components from the wall opening, especially the air regulation system, for cleaning. Summary of the invention

[0008] The invention presented in this document aims to solve this problem and is intended to provide an air extraction vent for a room with a functional aesthetic that integrates harmoniously into living and working spaces, and facilitates the cleaning of its parts and components for optimized management of indoor air quality.

[0009] To this end, the invention relates to an air extraction vent for ventilating a room, intended to be installed in an opening in a wall. The vent comprises a first end, visible from the room to be ventilated and located completely within or flush with the opening in the wall. The vent also has a second end connected to a ventilation duct via a connecting element. A cover forms the first end, and the assembly is removably mounted on a sleeve that forms the second end. This allows a user to remove the cover and access the sleeve. The sleeve has a longitudinal axis (X-X') and is composed of a first part, connected to the cover, and a second part, connected to the ventilation duct via the connecting element.Advantageously, the two parts are mounted removablely using a manipulation means configured on the first. part, thus allowing the disengagement of this first part of the cuff from the opening in the wall.

[0010] Preferably, the handling means configured on the first part of the cuff is a pivotally mounted handle on the element of said part facing the room to be ventilated, allowing the first part to be disengaged from the second part of the cuff. This handle can pivot between an upright operating position and a resting position in which it is recessed into a corresponding recess in the element of the first part of the cuff facing the room to be ventilated.

[0011] Preferably, the first part of the sleeve is equipped with at least one lug. The second part of the sleeve is equipped with at least one slot serving as an entry for said lug into a hollow guide track. The latter is arranged substantially along the transverse direction of said second part, until it reaches at least one stop in said guide track.

[0012] Preferably, the first part of the cuff is also equipped with a means for measuring one or more of the following: pressure, airflow, temperature, and humidity, and a movable flap for regulating the airflow. The movable flap can be automated using devices such as electric, pneumatic, or hydraulic actuators, and electrical control means configured to vary the airflow through the opening by adjusting the closing means between the closed and open positions of the flap, as a function of one or more of the following: pressure, airflow, temperature, and humidity.

[0013] Advantageously, the first part of the cuff is equipped on its surface with sealing means, these means being configured to adhere tightly to the second part when the two parts are assembled. This prevents the passage of air through the interface between the first and second parts, thus ensuring the structural and functional integrity of the air extraction vent.

[0014] To allow the extraction port to be located completely within or flush with the opening of the wall, the area of ​​the first end of the port is less than the area of ​​the wall opening. The cover forming the first end is attached to the cuff, removably, by means of a fastening means.

[0015] Preferably, the fastening means comprises an external thread designed to allow the insertion and removable attachment of said cover to the sleeve. The sleeve has an internal opening with a corresponding thread designed to receive the external thread of the cover in a complementary fashion. The external thread of the cover and the internal thread of the sleeve opening are configured to allow fastening by screwing, thus ensuring a secure and removable connection.

[0016] Preferably, the hood is always conical, pyramidal or tapered in shape, with the first end forming the base.

[0017] The method for inserting the air extraction vent is carried out in three steps. The first step consists of connecting the second part of the sleeve to the ventilation duct via the connecting element before the wall is installed and the opening in the wall is created. The second step consists of securing the first part of the sleeve to the second part. First, the first part must be inserted into the opening in the wall, and then inserted into the second part of the sleeve by placing the tab of the first part into the inlet slot of the second part. Next, using the sleeve's handling means, such as a handle, it must be rotated about the longitudinal axis of the sleeve (X-X') so that the tab is guided to the stop by the hollow guide track. This ensures that the sleeve is in the installed position.Finally, a third step consists of attaching the cover to the cuff using the fastening means.

[0018] Advantageously, the extraction method for maintaining the air extraction vent is also carried out in two steps. The first step consists of removing the cover from the cuff using the fastening means. The second step consists of rotating the cuff about the longitudinal axis of the cuff using the handle so that the lug is guided, by the hollow guide track, from the stop to the inlet slot of the second part of the cuff, then removing the first part of the cuff from the second part, and then from the opening in the wall for maintenance. Brief description of the drawings

[0019] The invention will be better understood upon reading the following description of an embodiment of the invention given by way of non-limiting example, with reference to the accompanying drawings, in which: - Fig. 1 illustrates an air extraction vent according to the invention, in a position installed in a wall, in longitudinal section. - Fig. 2 illustrates the air extraction vent according to the invention, in perspective view, exploded view. - Fig. 3 illustrates the air extraction vent according to the invention, in the installed position in the wall, in front view. Detailed description of the invention

[0020] The invention relates to an air extraction vent (1) for ventilating a room. This room may belong to a residential, commercial, institutional, or recreational building. The air extraction vent (1) is intended to be installed in an opening in a wall (2). The term wall (2) is to be taken in a broad sense here, as it can Whether it is a wall or a ceiling of a room, it is therefore a structure that serves to delimit or separate a space to create a room. The air extraction vent (1) comprises a first end (5) and a second end (6).

[0021] Figure 1 shows the invention installed in an opening in a wall (22). In this configuration, the extraction vent (1) has its first end (5), visible from the room to be ventilated, located completely within or flush with the opening in said wall (2). This improves the aesthetics while preventing dust accumulation. Its second end (6) is connected to a ventilation duct (3) via a connecting element (4), which is itself connected to a ventilation duct (3). The role of a ventilation duct is to transport air between different parts of a building or to the outside.

[0022] A cover (7) forms the first end (5) of the extraction vent. As illustrated in [Fig. 2], this cover is conical in shape, with the first end (5) forming its base. However, in other embodiments, the cover (7) may be pyramidal or tapered in shape. It serves to conceal the rest of the extraction vent from view by people in the room, thus acting as a decorative and aesthetic element. The cover (7) also serves to guide the air uniformly towards the rest of the air extraction vent (1). Finally, it plays a safety role by preventing accidental contact with the internal moving or electrical parts of the extraction vent (1). This cover (7) is made from materials with good durability, aesthetic appeal, corrosion resistance, and cost-effectiveness. Examples include ceramic, wood, metal such as aluminum, or PVC.

[0023] A sleeve (8) forms the second end (6) and has a longitudinal axis (X-X'). The sleeve serves to connect the air extraction vent (1) to the ventilation duct system, i.e. the ventilation duct, but also to facilitate maintenance of the extraction vent (1). This sleeve (8) is composed of a first part (9) and a second part (10), the two parts being removably mounted by means of a handling means (11) configured on the first part (9), thus allowing the disengagement of the first part of the sleeve (9) from the opening in the wall (2). The [Fig.[l] describes that the first part of the sleeve (9) is equipped on its surface with sealing means (20), these means being configured to adhere airtight to the second part (10) during the assembly of the two parts, in order to prevent the passage of air through the interface between the first part (9) and the second part (10), thus ensuring the structural and functional integrity of the air extraction vent (1) when installed. These sealing means may be foam, rubber, or neoprene gaskets. The choice of material is made by a person skilled in the art according to the specific installation conditions, such as temperature, humidity, and durability requirements.

[0024] In a preferred embodiment, the handling means (11) configured on the first part of the cuff (9) is a handle pivotally mounted on the element of said part (9) facing the room to be ventilated, allowing the first part (9) to be disengaged from the second part of the cuff (10). Figure 2 illustrates that the handle (11) can pivot between an upright operating position and a resting position, in which it is recessed into a corresponding recess (12) in the element of the first part of the cuff (9) facing the room to be ventilated. To achieve this pivoting, one embodiment is to have the handle (11) equipped with a circular projection at its outer ends, while one of the side walls of the recess (12) is provided with an opening to accommodate this circular projection. However, other embodiments of this pivoting handle can be used.

[0025] In a configuration as shown in [Fig. 2], the first part of the sleeve (9) is equipped with at least one lug (14), while the second part of the sleeve (10) is equipped with at least one slot (15). A lug is a projecting element used to block or limit the relative movement between two parts. It is generally a small protrusion or appendage extending from a mechanical part. The slot (15) serves as an entry point for the lug (14) into a hollow guide track (16), the latter being arranged substantially along the transverse direction of the second part (10) and in its inner portion. This allows the lug to be guided by this guide track (16) until it reaches a stop (17) when the user rotates the sleeve about the longitudinal axis (X-X') using the manipulation means (11).Reaching this stop (17) allows the two parts of the cuff (9, 10) to be assembled when it is in the installed position, as illustrated in [Fig. 1].

[0026] In one embodiment, the extraction vent (1) may be equipped with a measuring means (18). This means (18) is designed to measure a physical value of importance in order to improve the operating performance of the extraction vent (1). These physical values ​​are pressure, airflow, temperature, and humidity. The measuring means (18) must be capable of measuring one or more of the aforementioned physical values. In a first embodiment, the measuring means (18) may be a capacitive humidity sensor, i.e., a dielectric material placed between two electrodes, whose dielectric constant varies with humidity. When the air humidity changes, the dielectric constant also changes, thus modifying the sensor's capacitance. A differential pressure sensor is also added to the means (18) to measure the pressure difference between two points.In a second embodiment, the measuring means (18) measures humidity with a resistance sensor, or resistance hygrometer and a transducer. pressure to measure pressure. A person skilled in the art will use the most appropriate sensors due to their accuracy, robustness, and ease of integration into ventilation systems. Figure 2 illustrates a particular method of placing the measuring means (18) on the first part of the cuff (9). Depending on the physical value being measured, the placement of the measuring means (18) may vary on the first part of the cuff (9). This first part (9) is also equipped with a movable valve (19) to regulate the airflow. This valve (19) is a component that includes one or more movable parts (such as a valve, a disc, or a flap) that open or close to regulate the passage of fluid. The movement of these parts is actuated by the fluid pressure or by mechanical, electrical, pneumatic, hydraulic, or manual actuators.

[0027] In one embodiment, the valve (19) is automated using devices such as electrical, mechanical, pneumatic or hydraulic actuators, and electrical control means configured to vary an airflow through the mouth by adjusting the closing means between the closed and open positions of the valve (19), as a function of one or more elements among pressure, airflow, temperature and humidity.

[0028] Figure 3 shows the air extraction vent according to the invention, in position installed in the wall, viewed from the front. It can be seen that the area of ​​the first end (5), consisting of the cover (7), is less than the area of ​​the opening in said wall (22). This allows the air inlet opening to be created and the extraction vent (1) to be located completely within or flush with the opening in said wall (2).

[0029] Fig. 2 illustrates that the hood (7) and the cuff (8) are mounted removable. This is achieved using a fastening means (21) between the hood (7), forming the first end (5), and the sleeve (8). In a preferred embodiment, this means (21) has an external thread (21') designed to allow the insertion and removable fastening of said hood (7) to the sleeve (8); the sleeve (8) having an internal opening (21”) with a corresponding thread designed to receive the external thread of the hood (21'); the external thread of the hood (21') and the internal thread of the opening (21”) of the sleeve (8) are configured to allow fastening by screwing, thus ensuring a secure and removable connection.

[0030] Other variants of the fastening means (21) can be considered, such as a system with fastening clips.

[0031] The method for inserting the air extraction vent (1) is carried out in three steps, the first step consisting of connecting the second part of the sleeve (10) to the ventilation duct (3) via the connecting element (4). Then, the wall (2) and the wall opening (22) are formed. The sleeve (10) is therefore attached to the connecting element (4) before the wall (2) is constructed. The The second step consists of securing the first part of the cuff (9) to the second part (10) by inserting the first part (9) into the opening in the wall (22), and then inserting it into the second part of the cuff (10) by placing the lug (14) of the first part (9) into the inlet slot (15) of the second part (10). Using the cuff handling means (11), the cuff is rotated about its longitudinal axis (X-X') so that the lug (14) is guided to the stop (17) by the hollow guide track (16), ensuring that the cuff (8) is in the installed position. The third step consists of attaching the cover (7) to the cuff (8) using the fastening means (21). At this point, the air extraction vent (1) is in the installed position as described in [Fig. 1].

[0032] The method for removing the air extraction vent (1) for maintenance is the reverse of the insertion method. It is carried out in two steps because it is for maintenance; only the cover (7) and the first part of the cuff (9) need to be removed for cleaning. The second part of the cuff (10) remains installed. The first step consists of removing the cover (7) from the cuff (8) using the fastening means (21). The second step consists of rotating the cuff (11) about the longitudinal axis of the cuff (X-X') so that the lug (14) is guided, by the hollow guide track (16), from the stop (17) to the inlet slot (15) of the second part of the cuff (10). The first part of the sleeve (9) is removed from the second part (10), then from the opening in the wall (22) in order to perform maintenance.

[0033] It goes without saying that the present invention has been described above only by way of explanation, but in no way limiting, and that all variants may be made to it without going out of its scope.
