Definitions

  • the present invention relates to the field of ventilation and/or air conditioning installations.
  • the invention relates to an aeraulic connection for connecting an aeraulic duct to an aeraulic box, for example a controlled mechanical ventilation box.
  • the invention also relates to an aeraulic kit comprising such an aeraulic connection and an aeraulic box as well as a method of connecting such an aeraulic kit.
  • the regulating body For the modulation of the air flow circulating through an air duct, it is known to have a flow regulating member in series with this air duct. In other words, the regulating member is arranged across or at one end of the air duct.
  • the regulating body generally comprises a movable wall making it possible to obstruct the passage of air through the air duct to a greater or lesser extent. This regulating body is electrically powered for controlled or automatic operation.
  • This type of ventilation duct is generally connected in an aeraulic manner at one end to an aeraulic box, for example a controlled mechanical ventilation box, otherwise called “VMC”.
  • VMC controlled mechanical ventilation box
  • Such an air box generally comprises a ventilation group generating air circulation inside one or more air ducts and which is electrically powered, generally via a general building network. It is therefore easier to electrically connect the regulating body to the ventilation box to avoid an additional length of electrical cable and facilitate the electrical connection.
  • An air connection 10 comprises a body 12 defining an air passage channel 13.
  • the passage channel 13 defines an aeraulic diameter corresponding to the section of an aeraulic sheath 16 to be connected to the aeraulic connector 10.
  • a rotary valve 14 is arranged in this passage channel 13 so as to be able to modify the air passage section through the passage channel 13 and thus modulate the air flow passing through the air connection 10.
  • the rotary valve 14 is moved in rotation by means of a motor 15 disposed outside the body 12, therefore outside the aeraulic diameter.
  • the aeraulic connection 10 comprises a control box 18 for controlling the motor 15.
  • the control box 18 is also arranged outside the body 12, therefore outside the aeraulic diameter.
  • This control box 18 includes an electrical connector which can be electrically connected to the ventilation box by means of an electrical wire.
  • the electrical connector of the ventilation box is generally arranged inside the ventilation box at the level of an electronic control unit.
  • the aeraulic connection 10 is fixed to an aeraulic box at one end and fixed at an end opposite to an aeraulic sheath 16 by means of an intermediate part 17.
  • This intermediate part 17 forms an external surface 19 around which the air sheath 16 is threaded.
  • the intermediate piece 17 is fixed to the aeraulic connection 10.
  • the installer When connecting the ventilation connection 10, the installer mechanically fixes the end of the ventilation connection 10 to the ventilation box, for example by means of a bayonet type system. This mechanical fixing allows an air connection of the air connection 10 with the air box. Then, the installer electrically connects the ventilation connection 10 to the ventilation box using an electrical cable which he plugs into an electrical connector carried by each of them. Finally, the installer fixes the air sheath 16 to the intermediate piece, for example using adhesive tape, and ends up mechanically connecting the air connection 10 with the intermediate piece.
  • a major disadvantage of this type of aeraulic connection is that it requires the installer to perform numerous actions or assembly steps to achieve the mechanical, aeraulic and electrical connection of the aeraulic connection. This results in increased complexity of the installation which makes it longer and more difficult for an installer, particularly a non-professional. In addition, the large number of actions leads to an increase in the risk of poor connection of the air connection.
  • the document FR-A-2944588 describes an air connection comprising the characteristics of the preamble of claim 1.
  • the ventilation connection makes an electrical connection with an ventilation box simultaneously with its mechanical connection to said ventilation box. It is thus possible to connect all the functionalities of the aeraulic connection (electrical, electronic, mechanical and/or aeraulic) in the same fixing step.
  • the aeraulic connection can thus be brought closer to a “plug-and-play” configuration, greatly facilitating the installation of this aeraulic connection.
  • the fixing system is configured to allow a simultaneous connection using at most two movements of said aunterlic connector.
  • the electrical connector is arranged at a facade of the ventilation connection, said facade being intended to face the ventilation box.
  • the aunterlic connection comprises an external wall configured to receive and hold in position a portion of aeraulic sheath and defining an aeraulic diameter, the modulation member and the control box being arranged inside of this aeraulic diameter.
  • an air flow passage channel is formed through the air flow connection, the electrical connector being arranged outside the air flow passage channel to isolate the electrical connector from a flow of air circulating through the passage channel.
  • the aunterlic diameter is divided so as to form a first portion receiving the control box and a second portion forming the passage channel of the air flow and intended to cooperate with a channel for receiving the air flow from an aunterlic box, the electrical connector opening at the end of said first portion.
  • the air flow passage channel forms an airtight flange at one end of the air flow passage channel intended to cooperate with a channel for receiving the air flow from an aunterlic box.
  • said fixing system comprises a locking member configured to be arranged in a locking position of the connection on said ventilation box.
  • the assellic connection further comprises a connection body, the locking member being movable relative to said connection body between said locking position and an unlocking position.
  • the locking member is a ring movable in rotation, said ring comprising at least one main locking relief configured to cooperate with at least one secondary locking relief formed on the aunterlic box when the ring is in the locked position.
  • the air connection it comprises a visual indicator configured to transmit information to a user.
  • This visual indicator may include one or more of a light indicator, a symbol alignment, or an information display.
  • This visual indicator is preferably configured to indicate to the user the complete connection between the air connection and an air box.
  • the visual indicator can for example transmit at least two types of information: incomplete connection information (for example in the form of a visual indicator of red color) and complete connection information (for example a visual indicator of color green).
  • the air connection may comprise a transparent wall or portion of a wall behind which the visual indicator is placed. The user therefore has assistance with the correct connection of the a Vogellic connection, which makes its installation more reliable and saves time during installation. Visual maintenance of the installation can also be facilitated by this visual indicator.
  • the air connection may include an audible indicator to transmit information to the user.
  • the ventilation connection can be configured to emit a sound when the ventilation connection is completely connected to an ventilation box, i.e. electrical, ventilation and mechanical connections.
  • the invention also proposes an aeraulic kit comprising an aeraulic box, for example a controlled mechanical ventilation box, and at least one ventilation connection as described above, said ventilation box comprising at least one electrical power connector disposed at said at least one tap, said at least one electrical power connector being configured to be arranged opposite the connector electrical connection of the aeraulic connection when the aeraulic connection is fixed to said aunterlic box.
  • the electrical connector of the aunterlic connector and the electrical power connector of the aunterlic box are configured to be in contact with one another when the aunterlic connector is fixed to said aunterlic box.

  • An air duct is generally circular or quasi-circular (flattened circular) in section but any shape can be used.

  • An insulating layer can be placed around the air duct to limit thermal losses.
  • An example of an air duct is illustrated in figure 1 .
  • ventilation box means a box comprising a plurality of orifices to which ventilation ducts can be connected in an aunterlic manner.
  • the box comprises a plurality of orifices intended to be connected to air ducts opening into rooms of a building and an orifice intended to be in fluid communication with the exterior of the building or a technical room.
  • the air box is thus a point of convergence of air ducts of an air circuit between ventilated rooms of a building and one or more exterior or unregulated rooms of this same building.
  • Such an air box is preferably a controlled mechanical ventilation (VMC) air box or an air conditioning box of an air conditioning installation.
  • the ventilation box includes a ventilation group generating air circulation inside the ventilation ducts to which it is connected. It is thus possible to suck up stale air from the rooms of the building where the air ducts are installed so as to discharge it outside of this building. Alternatively, it is possible to blow healthy air from outside or from an unregulated room in the building to the rooms where the air ducts lead.
  • the ventilation box is connected to a building electrical network to electrically power the ventilation unit.
  • aeraulic connection means a part configured to be fixed in a watertight manner between an aeraulic box and an aeraulic duct.

More generally, the external wall 24 can be of any shape. The dimensions of the external wall 24 are configured to allow a tight connection of the air duct to the air connection 20.
