Description

Air difusor.

Object of the invention

The present invention relates to a diffuser of air, used interchangeably in heating installations or of refrigeration, as well as, logically, in facilities of air conditioning.

The object of the invention is to achieve a diffuser intended to be located at considerable height with with respect to the ground, and to move large air flows, with a considerable horizontal reach.

It is also the object of the invention to achieve a diffuser easy assembly and disassembly, with a very aesthetic attractive

The diffuser is especially suitable for being used in the air conditioning of spaces such as offices, banks, dealers, auditoriums, etc.

Background of the invention

As is known, in the facilities of hot and cold air conditioning ducts are used generally embedded in false ceilings, false beams, etc., which they are finished off in diffusers through which the air accesses the cabin to be conditioned thermally.

Conventional diffusers, to get acceptable results from the point of view of air conditioning, are of relatively reduced flow, since its scope is also reduced, so that this limitation functional is corrected by increasing the number of diffusers, which It obviously complicates the installation.

This horizontal range limitation force also to the use of multiple fins that suppose to the diffuser an outdated and unattractive aesthetic, especially when the existence of regulatory means of flow, which are usually complex in themselves and of difficult handling

Description of the invention

The air diffuser that the invention proposes solves the problem fully satisfactorily previously exposed, in the different aspects commented.

For this said diffuser, which as before it has been said it is specially designed to be implanted to considerable heights, preferably between 2.7 and 3.5 m., designed in parallel to move large air flows with a single diffuser and with important horizontal scopes, between 1.5 and 5 m. driving cold air, is structured based on a trunk-conical body opened by its bases, which in correspondence with its minor base and upper extends axially in a cylindrical neck, and at level of its main and lower mouth in a wall or circular crown included in an imaginary plane perpendicular to the aforementioned axis body.

Within the cylindrical neck mentioned establishes a second trunk-conical body, considerably smaller, closed by its smaller base and upper, base that is conveniently reinforced with the collaboration of two washers with a diameter close to that mentioned core of the trunk-colic body, washers that together with said base they configure a kind of sandwich in that these elements are in solidarity with the collaboration of rivets The second trunk-conical body, with its washers reinforcement, is axially retained with the collaboration of a hex nut on a screw or threaded rod, in solidarity with the aforementioned fixing bridge and arranged in position falling.

As a complement to the structure described, the lower mouth of the trunk-conical body interior are fixed by tongue and groove a series of pieces fixed by welding or similar to a lower disk, completely flat, which mostly closes the mouth lower external trunk-conical body, with exception of a perimeter strip that constitutes the air outlet of the diffuser.

From this basic structuring is feasible that, when the diffuser is going to be placed on a false roof and replacing one of the constituent plates of the same, the perimeter wall of his body outer conical trunk is associated with a plate quadrangular, of dimensions coinciding with the aforementioned plate suspended ceiling to which it will replace.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows an elevation view side of an air diffuser made in accordance with the object of The present invention.

Figure 2.- Shows the same set of the previous figure, now diametrically sectioned.

Figure 3.- Shows a detail in perspective from the external elements of the diffuser.

Preferred Embodiment of the Invention

In view of the figures outlined you can be observed as the diffuser that the invention proposes is constituted from an outer body (1) in which it is defined a large central configuration sector conical trunk, which corresponds to the own reference (1), prolonged at its lower and upper mouth at a cylindrical body (2) and topped by its lower mouth and larger diameter in a perimeter wall (3), which constitutes the form of support of the diffuser on the marginal area of the ceiling that delimits the hole in which said diffuser is to be implanted.

The cylindrical neck (2) is fixed by rivets (4) a clamping bridge (5), which is observed especially in the perspective of figure (3), where you can see the "T" configuration thereof, based on profiles ribbed and soldiers that is topped by its free ends in perforated plates (6) for passing said rivets (4).

Said bridge (5) constitutes the support for a second trunk-conical body (7) established inside of the main body and also trunk-conical (1) of the diffuser, considerably smaller than the latter, with its lower and upper base (8) closed and reinforced by two washers (9 and 10) located on both sides of the base (8) and fixed to the latter with the collaboration of rivets (11) through of holes (12) of these elements.

The base (8) of the body internal conical trunk (7) has a hole central (13), coaxially facing holes (14 and 15) of the washers (9 and 10), for the passage of a threaded rod (16), preferably materialized in a screw, fixable immovably, for example by welding, to the center of the fixing bridge (5), as seen in figure 3, receiving said screw (16) to a nut (17) with which it is carried out a solid fixation.

The inner trunk-conical body (17) presents its rounded lower and free edge, and at the same couple several support pieces (18) of L-profile, whose branch vertical (19) has recesses (20) for coupling the cited flange or rounded edge, while its horizontal branch (21) receives solidarity, by welding, to a flat disk (22) which constitutes the majority visible element of the diffuser in mounting situation for it, and that definitely determines the air outlet (23) for the diffuser.

It only remains to point out finally that, as has already been noted above, the wall (3) that constitutes the element of end in the coupling of the diffuser on a hole Operationally practiced on a roof, it can be adapted and fixed to a quadrangular contour plate, prolongation of said wall (3), to integrate the diffuser into suspended ceilings of quadrangular plates mounted on a support structure.
