Description

Title of the invention: Air intake or extraction vent technical field

[0001] The present invention relates to the field of ventilation of an area of ​​a building, for example a dwelling.

[0002] Its object is more particularly a suction or extraction vent for the ventilation of air in a room or part of a building. Previous technique

[0003] It is known that mechanical ventilation of an area of ​​a building such as a room in a single-family dwelling provides many advantages.

[0004] It first allows for the improvement of air quality in this area, by helping to reduce the concentration of indoor pollutants such as carbon dioxide (CO2), volatile organic compounds (VOCs) and allergens.

[0005] By promoting air circulation in this area, it also helps to prevent excessive condensation on interior surfaces, reducing the risk of mold growth.

[0006] It can also allow humidity control within this area.

[0007] In general, the ventilation systems of a building include a group of ventilation connected to one or more air intake or exhaust vents by ducts, or suction ducts.

[0008] For example, such a ventilation unit can be placed in the attic of this building, while the air intake or exhaust vents are arranged in different areas or rooms of this building.

[0009] In order to limit the fouling of ducts or other elements such as a heat exchanger, placed on a ventilation system, it is necessary to coarsely filter the air to remove the aspirated dust and grease.

[0010] This filtration is typically carried out on a double flow VMC type ventilation system, by one or more filters placed at the level of the ventilation unit.

[0011] In the case of a single-flow VMC type ventilation system, conical filters are known to be placed in each duct.

[0012] However, since these filters are components that must be installed in situ by the user, they are very rarely used. It is then necessary to clean the ducts themselves, with the inherent difficulties, particularly regarding accessibility.

[0013] Thus, it is essential not only to implement filters, but also to clean or replace them regularly in order to avoid clogging them.

[0014] Indeed, the appearance of such clogging would be likely to cause pressure losses, or even prevent air circulation in certain parts of the ventilation system.

[0015] A first disadvantage of existing ventilation systems is that access to these filters is difficult for a standard user, given their positioning in the suction ducts.

[0016] In addition, the intervention of a qualified operator can prove costly.

[0017] A second drawback is that while a filter can be cleaned, the structure of its constituent medium can be altered by such cleaning. It is therefore suggested that such a filter be replaced after a few cleanings.

[0018] However, here too, handling the filter is delicate to avoid any risk of releasing pollutants. Object of the invention

[0019] The present invention aims to overcome the disadvantages of the prior art and to meet the constraints stated above by proposing an air intake or extraction vent, simple in its design and in its operating method, allowing particularly easy handling and maintenance of the filters of a building's ventilation system.

[0020] Another object of the present invention is such an air intake or extraction vent whose filtration element is advantageously economical.

[0021] This teaching also relates to a ventilation system for a building comprising such air intake or exhaust vents. Description of the invention

[0022] For this purpose, the invention relates to an aspiration or extraction vent for the ventilation of air in an area, said vent being intended to be mounted on a wall delimiting said area, such as a wall or a ceiling, said vent comprising a vent body defining an air passage, at least a part of said vent body being intended to protrude from said wall into said area and comprising an air inlet. According to the invention, - said at least one part of said mouth body comprises a lateral opening and a housing into which said lateral opening opens - a support being mounted to slide through said opening between an inserted position and a retracted position, said inserted position corresponding to a position in which said support is received in said housing, being placed opposite said air inlet and extending at least partially into said air passage, - said support containing or supporting one or more air filtration elements being configured to allow the passage of air through at least a portion of said air filtration element(s).

[0023] The original design of this air intake or extraction vent advantageously allows for very easy changing of the filtration element(s) from an area to be ventilated in a building.

[0024] Indeed, said at least a part of the mouth body is visible on the wall and therefore accessible from the room or part of the building in which it is mounted.

[0025] When the mouth body comprises a first visible mouth body part and a second mouth body part placed in the extension of this first body part, the latter is intended to be connected to a ventilation duct or conduit placed inside a housing delimited in part by the wall.

[0026] The body of this air intake or exhaust vent is advantageously a single piece made of a single plastic material. Of course, it may include one or more added elements, notably a flap for automatic closure of the intake vent, or a ventilation system fault detection device such as a pressure sensor to measure the pressure between the air inlet and outlet of this vent, or even a humidity-controlled sensor.

[0027] The retracted position corresponds to a position in which the support is at least partially withdrawn from this first body part, for example, in the case of a tray or drawer, to make the filter element(s) accessible to the user. This support may, however, still be connected to said first body part by being placed outside the first mouth body part. Alternatively, if not connected to the latter, or if attached, this support may be completely removed or extracted.

[0028] According to a particular embodiment of this air intake or extraction vent, said vent body comprises a first body part intended to project from said wall in said area and a second body part placed in line with said first body part and intended to be connected to a duct, said first part comprising an air inlet, and - said first body part comprises a lateral opening and a receiving and support part onto which said lateral opening opens, - a support being mounted to slide through said opening between an inserted position and a retracted position, said inserted position corresponding to a position in which said support is received on or in said receiving and support part, being positioned opposite said air inlet and extending at least partially into said air passage

[0029] According to another particular embodiment of this air intake or extraction vent, this support is chosen from the group comprising a cassette, a drawer or a tray, which are perforated to allow the passage of air.

[0030] Of course, when dealing with a cassette, the filter element(s) are entirely contained within the body of the cassette. The latter may be perforated or take the form of a mesh to allow air to pass through.

[0031] Preferably, said tray or the bottom of said drawer has a central opening.

[0032] According to yet another particular embodiment of this air intake or extraction vent, said support includes a sealing element for closing said lateral opening.

[0033] This sealing element can be a simple gasket ensuring the sealing of the mouth at the level of the lateral opening.

[0034] According to yet another particular embodiment of this air intake or extraction vent, said support includes a gripping element such as a handle, shaped to correspond to said opening and thus ensure a surface continuity of said first body part at the level of said opening.

[0035] By way of pure illustration, this lateral opening being placed on a rounded portion of said first part of body, said support includes a rounded gripping element to fit into said opening and ensure a surface continuity of said rounded portion.

[0036] According to yet another particular embodiment of this air intake or extraction vent, said receiving and support part comprises two surfaces placed opposite each other and extending in a sliding direction of said support, said surfaces defining a housing to receive and retain at least in part said support.

[0037] By way of illustration only, it may simply be a peripheral opening in the thickness of said first part of the body, this opening opening laterally, or specially adapted jaws communicating with a lateral, or peripheral, opening in the first part of the mouth body.

[0038] According to yet another particular embodiment of this air intake or extraction vent, said receiving and support part includes one or more guide elements for sliding said support such as a guide rail or pads.

[0039] According to yet another particular embodiment of this air intake or extraction vent, this vent includes a mechanism for locking / unlocking said support in position on or in said receiving and support part and a mechanism for activating the unlocking of said support, optionally a mechanism for moving said support to its withdrawal position.

[0040] According to yet another particular embodiment of this air intake or extraction vent, said support is made of a cellulose-based material such as cardboard or kraft paper.

[0041] Advantageously, such a design defines a consumable element whose cost price is particularly advantageous.

[0042] According to yet another embodiment of this air intake or extraction vent, said support is in one piece and made of a single plastic material, wood, metal or even a composite material.

[0043] Preferably, it is a rigid plastic material such as PA5, ABS, PS, PS / PE, HDPE, PP, PETG, PMMA, PVC, POM, PET or other.

[0044] According to yet another embodiment of this air intake or extraction vent, said filtration element is a synthetic fiber filter or a natural fiber filter.

[0045] According to yet another embodiment of this air intake or extraction vent, the vent body is made in one piece of plastic material.

[0046] The present invention also relates to a ventilation system for an area of ​​a building such as a dwelling, comprising an air intake or exhaust vent as described above, a ventilation unit and an air circulation duct connecting said ventilation unit to said air intake or exhaust vent.

[0047] The present invention further relates to a filter cartridge for a suction or extraction mouth as described above.

[0048] According to the invention, this cartridge comprises a cartridge body configured to be inserted through the lateral opening of said first part of body, said cartridge body defining a housing in which at least one air filtration element is placed, this housing being open for the passage of air through said filtration element, said cartridge body being made of a cellulose-based material such as cardboard or kraft paper.

[0055] [Fig.6] is a bottom view of the air intake or exhaust nozzle illustrated in [Fig.3]; Description of the implementation methods

[0056] The drawings and description below contain, essentially, elements of a definite nature. They may therefore not only serve to better understand the present invention, but also contribute to its definition, if necessary.

[0057] First of all, it should be noted that the figures are not to scale.

[0058] Figures 1 and 2 schematically illustrate an air intake vent 1 according to a particular embodiment of the present invention.

[0059] The body of this air intake vent 1 comprises an axial conduit 2, with longitudinal axis A, intended to be placed in an opening in a wall such as a wall, and provided at one of its ends with a radial flange 3 for support on this wall.

[0060] This radial flange 3 defines an air inlet while the opposite end of the axial duct 2 determines an outlet for air drawn from this suction mouth 1.

[0061] This other end of the axial duct 2 receives a sealing gasket 4 for the connection of an air extraction duct (not shown) of a mechanical ventilation system. This mechanical ventilation system may include a heat exchanger and one or more ventilation units.

[0062] The body of this suction nozzle 1 is here made in one piece from a rigid plastic material such as acrylonitrile butadiene styrene (ABS). Alternatively, it could result from the assembly of initially separate parts.

[0063] The axial duct 2 defines an air passage between the air inlet and the air outlet.

[0064] The first body part 3 has a peripheral or lateral slot 5, which opens onto a housing 6 formed by a recess in the thickness of the first body part 3.

[0065] This housing, or receiving and support part, 6 is intended to receive and support a drawer 7.

[0066] This drawer 7 is mounted to slide, or to be movable in translation, through the lateral slot 5 between an inserted position and a withdrawn position in which it is possible to extract it completely.

[0067] In the inserted position, this drawer 7 is placed opposite the air inlet of the suction mouth 1 and extends transversely, or substantially transversely, in the air passage so as to be placed on the path of the air drawn in by this suction mouth 1.

[0068] This drawer 7 includes an air filtration element 8 and its bottom has a circular opening to allow air to pass through this filtration element 8.

[0069] The drawer 7 has a gripping handle shaped to ensure surface continuity of the first body part when the drawer is in the inserted position.

[0070] This drawer 7 is here made of plastic material.

[0071] Figures 3 to 6 schematically illustrate an air intake mouth 10 according to another particular embodiment of the present invention.

[0072] The elements shown in Figures 3 to 6, and bearing the same references as those illustrated in Figures 1 and 2, represent the same objects, which will not be described again below.

[0073] The suction mouth 10 illustrated in Figures 3 to 6 differs from that illustrated in Figures 1 and 2 in that the body 11 of this air suction mouth 10 is intended to be fixed by an adhesive on a wall or ceiling.

[0074] This suction mouth 10 therefore does not include a sleeve, or second part of a tubular body, extending from a radial flange 3 and intended to be inserted into a drum, or conduit.

[0075] By way of illustration only, this adhesive may take the form of a double-sided adhesive strip.
