Definitions

  • the present invention corresponds to the technical field of air conditioning diffusers, specifically the type placed and built into a false ceiling, such that the only visible portion of the diffuser is the outlet slit for the exit of air from the diffuser.
  • diffusers such as those described in ES1070582-U which are built into a false ceiling, keeping the entire assembly concealed from users' view except for the outlet slit for the exit of air from the diffuser, which is the only portion that is externally visible, emerged on the market.
  • said diffusers have the drawback that the mechanism regulating the air outlet direction is fixed and non-removable, so apparatuses must be chosen depending on where they will be placed, i.e., with the airflow oriented to the left or right depending on if the diffuser is to be placed in a portion of the ceiling close to a wall. Therefore, if the diffuser has a wall on its right side, for example, the airflow must be oriented towards the left and vice versa.
  • diffusers Given that the location of diffusers must often be changed, or due to the compartmentalization of a room, diffusers are adhered to a wall which was not previously there, said diffusers become rather impractical since in order to be reused they must be disassembled, generally in a factory since they are fixed or non-removable air outlet regulating mechanisms. Likewise, during the installation step, such diffusers to be used must be carefully chosen in the project phase since those diffusers having air outlet oriented towards a specific location are rarely usable or do not perform their function well for a distribution different from the intended distribution.
  • the ceiling diffuser for air conditioning installations of the present invention solves the problems of the state of the art mentioned above since it comprises removable regulating means for regulating the direction of airflow, thus making it a versatile and practical diffuser.
  • the diffuser of the invention is of the type fitted into a false ceiling, only the outlet slit for the exit of air being externally visible and basically comprising a hollow longitudinal main body, and the removable regulating means for regulating the direction of airflow being a laminar part located on securing bridges of the main body through removable securing means such that changing the position of said laminar part with respect to said securing bridges and therefore to the main body is allowed for regulating the direction of airflow.
  • Said laminar part is structured such that its sides are bent forming respective flaps inclined towards the lower face thereof such that airflow is directed, where the maximum distance between said bends is less than the width of the securing bridges at that point, i.e., less than the width of the main body such that air passage is allowed.
  • these removable securing means are formed by screwed elements.
  • the hollow longitudinal main body (1) has two sides, each formed by an aluminum extrusion profile and attached to one another at their front and rear ends by a front cover (5) and a rear cover (6), respectively.
  • the upper face (7) of the main body (1) is open, like the lower face (8), forming the outlet slit (3) of the diffuser.
  • extrusion profiles forming the sides of the main body (1) of this diffuser are formed by a first vertical section (4.1) and a second section (4.2) inclined towards the inside of the main body (1), the latter being located after and below the first section (4.1).
  • the securing bridges (9) of the diffuser are located at an intermediate height of the first section (4.1) of the sides of the main body (1).
  • the laminar part (10) is symmetrical and comprises equidistant transverse movement guides (21).
  • the laminar part (10) in turn comprises bends on the longitudinal sides, such that they form respective flaps (11) inclined towards the lower face, such that the maximum distance between bends (12.1, 12.2) is less than the width of the securing bridges (9) at that point, i.e., less than the width of the main body (1). Therefore, since the position of the laminar part (10) can be changed, the difference in width of the laminar part (10) with respect to the main body (1) forms a free hole (13) for air passage.
  • Figure 2.1 shows a first position of the laminar part (10) in which said part is moved towards the left of the securing bridges (9), with the left bend (12.2) of said laminar part (10) in contact with the inside of the first section (4.1) of the left side of the main body (1) of the diffuser. Any possibility of air exiting through this side is thus blocked, directing the air to the free hole (13) generated on the right side of the securing bridge (9). Therefore, the air is expelled with an inclination towards the left due to the inclined flap (11) of the right, marking its path.
  • This position of the laminar part (10) is used in diffusers located with a wall located nearby on the right side.
  • Figure 2.2 shows the case of the opposite position of the laminar part (10), i.e., this part is moved towards the right with the right bend (12.1) in contact with the inside of the first section (4.1) of the right side and the air exits through the free hole (13) generated in the left portion of the securing bridges (9).
  • Figure 2.3 depicts a third possibility in which the laminar part (10) is located in the center with respect to the securing bridges (9), whereby two free holes (13) are generated on both sides of the part (10), where the air which the flaps (11) converge in the central area exits vertically. This position is suitable when the diffuser is not located close to any wall.
  • the diffuser comprises sealing means (14), such as a sealing strip or joint, for example, both when the laminar part (10) is located as in the case depicted in Figure 2.1 , and when it is located as in Figure 2.2 .
  • the diffuser in this preferred embodiment of the invention comprises securing means for securing to the false ceiling (2) which in this case are formed by L-shaped side profiles (15), which are fixed on the outer face of the first section (4.1) of the sides of the main body (1) and to the inner face of the false ceiling (2), thus acting as a fixed support for supporting the diffuser on the false ceiling (2).
  • Screwed elements (16) are used for fixing these L-shaped profiles (15) to the first section (4.1) of the sides of the main body (1) and to the false ceiling (2).
  • All the elements of the diffuser mentioned above will be made from a strong, light-weight material, such as aluminum for example, so a significant reduction of weight exerted on the false ceiling is achieved.
  • the diffuser of the present invention can be a single element in the manner shown until now or an in-line connection between several adjacent built-in diffusers.
  • the diffuser has in-line connection means which are formed by connecting elements (19) secured in securing flanges (20) distributed throughout the inner face of the extrusion profiles forming the first section (4.1) and the second section (4.2) of the sides of both main bodies (1) in each attachment.
  • the first diffuser has a front attachment cover (5) at the front end of the in-line connection
  • the last diffuser comprises a rear attachment cover (6) at the rear end of the connection
  • each connection between two adjacent diffusers comprises an intermediate cover (17) in the section attaching both diffusers.
  • connection between adjacent diffusers has reinforcements (18) consisting of respective L-shaped reinforcement profiles located on both sides of the intermediate attachment cover (17).
