Description

FIELD OF TECHNOLOGY

The utility model relates to the field of equipment for ventilation systems, in particular to linear slot diffusers for concealed installation, built into the ceiling, made of plasterboard (GKL) and a metal frame.

LEVEL OF TECHNOLOGY

Linear slot diffusers are used for installation in suspended ceilings in order to conceal the ventilation grill frame and ensure the required air distribution.

From the prior art, various types of linear diffusers for concealed installation are known, which, as a rule, form a common frame of a diffuser placed in a plasterboard ceiling. Examples of such solutions are diffusers known from sources ES 1064231 U, US 4537347 A, KR 20130108792 A.

As an analogue, one can consider the design of a slotted diffuser manufactured by Ritech (http://www.ritech.ro/_docs/188/188_1_20170907120816.pdf). The diffuser has a curved profile with a segment in the form of a cavity, framed by a frame, designed for attaching the diffuser to the plasterboard ceiling. The diffuser profile in the lower part contains a painting unit having a sharpened profile and made in the form of an angular thin frame.

The disadvantage of the profile design of the known solution is its low thermal insulation characteristics, and therefore, when cooling air passes through the diffuser channel, the risk of condensation on its walls increases, when used in rooms with a tropical humid climate, which significantly reduces the performance of the product. Also, additional disadvantages are: a decrease in the reliability and strength of the diffuser, which is due to the principle of execution of the frameless design of its profile; the used painting unit for finishing does not provide a strong fixation of the putty layer; ineffective direction of air flows, due to the internal geometry of the profiles, due to which the flows are weakly directed to the sides.

ESSENCE OF THE USEFUL MODEL

The claimed device is aimed at solving a technical problem in terms of creating an effective and reliable design of a linear slot diffuser, which eliminates the significant disadvantages of solutions known from the prior art.

The technical result is to increase the reliability and efficiency of the installation of the slot diffuser, by reducing the likelihood of delamination of the putty layer when external loads arise.

The claimed technical result is achieved due to a linear slotted diffuser made of two metal profiles, while on the lower parts of the profiles there is a painting unit made in the form of a profiled surface, while the surface profile is alternating protrusions and grooves, the distance between which is selected based on the total filling the groove with putty.

In another particular example of implementation, a locking protrusion is made on one of the sides of the profiled surface.

In another particular example of implementation, the lower part of the profiles is executed in the form

a segment that has a shape close to a right-angled triangle.

IMPLEMENTATION OF THE USEFUL MODEL

FIG. 1A shows a first embodiment of a profile (10) for a flush-mounted slot diffuser. The profile (10) is made of metal in the form of a solid product and contains a frame structure, which consists of three segments (11, 12, 13). Each segment (11–13) is a frame containing a void inside, the area of the inner space of which is greater than the area of the framing frame. In the presented example, the upper segment (11) contains three compartments with voids separated by the frame, however, it is obvious that the presented example of implementation does not limit the geometry of the segments.

Segments (11–13) are shaped and cast with an obtuse angle α, thereby forming the inner surface of the profile (10). The outer surface formed by the segments (11-13) is stepped due to the conjugation of the segments (11, 12). The lower segment (13) is predominantly in the shape of a right-angled triangle and forms a paint unit, the design features of which will be disclosed later in this application materials.

In the upper part of the profile (10), a groove (14) is made on its inner surface for attaching a decorative sheet of metal, and a ledge (15), which provides alignment of the power bridge connecting the two profiles (10) into a single rigid structure of the slot diffuser.

The presented version of the profile (20) in FIG. 1B is also made of three segments (21–23), which form the outer and inner surfaces of the profile (20). In this case, the placement of the segments (21-23) is made in such a way that the inner surface of the profile (20) forms two joints at an obtuse angle β and σ. The middle segment (22) has a frame that forms two compartments with voids, however, it is obvious that the presented example of implementation does not limit the geometry of the segments. The lower segment (23) is similar to the segment (13) of the profile (10) and is predominantly in the shape of a right-angled triangle and also forms a paint unit.

In the upper part of the profile (20), an extension is made, on which a groove (24) is made, intended for fastening a decorative metal sheet, and a step (25), which

provides alignment of the power bulkhead connecting the two profiles (20) into a single rigid structure of the slot diffuser.

An example of a profile variant (10) can be used for a slot of 10-40 mm, while a profile (20) for a slot with a width of 45-80 mm, which is achieved by adjusting the power bridge for a slot from 10 to 40 mm, and from 45 to 80 mm, respectively.

FIG. 2A - 2B show variants of diffusers (100, 200) formed by constructive connection of variants of profiles (10, 20). Each diffuser (100, 200) is formed by two identical versions of profiles (10 or 20), facing each other with internal surfaces and connected by means of a power bridge (16, 26), which is a rectangular element installed on a ledge (15, 25) and fixed using fasteners to the profile (10, 20). The power jumper (16, 26) provides the required structural rigidity. A decorative sheet of metal is installed in the grooves (14, 24), which covers the upper part of the diffuser (100, 200).

The diffuser (100, 200) contains in the central part a lamella fixing element (17, 27), made of a metal profile, on the sides of which there are lamella attachment points, in the grooves of which the lamellae (171, 172, 271, 272) are installed. The lamella fixing element (17, 27) provides closing and opening of the lamellas (171, 172, 271, 272) to regulate the air flows through the diffuser (100, 200).

The formed inner surface of the profiles (10, 20) with bends at an obtuse angle makes it possible to improve the direction of air flows passing through the diffusers (100, 200), due to the provision of a more dense direction of the air flow (adhesion) to the ceiling when one of the lamellas is closed.

FIG. 3 shows a painting unit (130) located on the lower segment (13) of the profile (10). The first version of the profile (10) is chosen as an example, since the painting unit and the geometry of the lower segment (13, 23) of the profiles (10, 20) are identical.

The painting unit (130) is a profiled lower surface of the lower segment of the profiles (10 or 20), made in the form of alternating protrusions (131) and grooves (132). The grooves (132) have a broadening (1321), which must be larger than the entrance part (1322) of the recess. For example, the ratio of the size of the broadening (1321) to the size of the part (1322) can be at least 1 to 1.2, which depends on the shape of the groove (132). Due to this ratio of the sizes of the parts (1321, 1322) of the groove (132), the putty (30), filling the entire groove (132), when it dries, it gets into a spacer and becomes self-supporting together with the finishing layer, which increases the reliability and efficiency of the diffuser (100 , 200), by reducing the likelihood of delamination of the putty layer (30) under external loads (for example, geometric displacement of the ceiling, shrinkage of the house, etc.). At the same time, it should be obvious to a person skilled in the art that the geometry of the groove (132) can be of a different shape, while maintaining the proportions of the base of the groove and its recess.

This type of geometry makes it possible, when finishing the diffuser (100, 200) installed in the gypsum board (31), by applying a layer of putty (30), to fill the grooves (132) with it and increase the adhesion of the layer (30). Segment (13) (as well as (23)) has a paint beacon (133), along which the finishing layer of putty (30) is leveled.

FIG. 4 shows the design of the lamella attachment unit (170) using the example of the first variant of the diffuser (100), while the second variant of the diffuser (200) contains a structurally identical element. The lamella attachment unit (170) is located in the profile of the element (17) and contains a recess for fixing the cylindrical part of the lamella (171), which ensures its rotation in the axial direction to block / open air flows and adjust their direction.

On the cylindrical part of each lamella (171, 172, 271, 272), at least two protrusions (1711 - 1721) are made, which provide rigid and reliable fixation of the lamellae in the unit (170) of their attachment at certain points, which is achieved when each protrusion stops (1711-1721) about the groove of the knot (170), preventing arbitrary displacement of the lamellas. It should be noted that the shape of the cylindrical part of the lamella (171) is given as an example and can be made of any other shape that ensures its reliable installation in the unit (170), as well as the number of protrusions (1711-1721) required for fixing and adjusting lamellae.

The placement of the protrusions (1711-1721) provides an increase in the reliability of fixing the lamellae when changing their position to adjust the air flow, which makes it possible to further improve the efficiency of the technical result, in terms of increasing the overall reliability of the structure in terms of eliminating the displacement of the lamellas when external loads occur, contributing to the possible displacement of the diffuser.

FIG. 5A - 5B show examples of fixing diffusers (100, 200) in the gypsum board (30) ceiling. The voids of the segments (11, 12, 22) are also intended for fastening the profiles (10, 20) to the plasterboard ceiling, through the corresponding fixing elements, which increases the reliability of its installation, due to the formation of a single rigid structure with a metal frame of plasterboard ceilings, made, for example, in the form of a ceiling profile (32), to which a diffuser (100, 200) is attached using fasteners (for example, self-tapping screws, screws, etc.).

The diffuser (100) is attached through the lower part of the segment frame (12) using self-tapping screws for metal fixing it to the metal frame (32) of the plasterboard ceiling. (31). The ventilation adapter (33) is fastened to the diffuser profile through the side part of the segment frame (11).

Through the side part of the frame (22), the diffuser (200) is attached to the metal frame (32) of the plasterboard ceiling. The diffuser (200) is attached to the ventilation adapter (33) through the upper side part of the segment frame (22).

FIG. 6 shows an example of a diffuser (100) (similar design also for a diffuser (200)) with a luminaire (40). The lamp (40) is attached to a platform (18) made in the form of a solid structure from a profile of a given shape, for example, trapezoidal. The platform (18) is divided into channels, in one of which there is a cable channel (181) for laying the wiring connected to the luminaire (40). The platform (18) is attached to the power jumper (16), forming a single and reliable structure, and also allows you to fix various types of lamps (40) by attaching them to the entire length of the platform (18) using fasteners, for example, self-tapping screws. In this case, an increase in the tightness of the cable channel (181) is achieved, due to the fact that the fixing of the lamp (40) is carried out in the voids of the adjacent channels, without touching the cable channel (181).

FIG. 7A shows the result of computational fluid dynamics of the claimed diffuser design using the example of a diffuser (100) with the first version of the profiles (10). It should be noted that for the diffuser (200), the test results are similar.

As seen in FIG. 7A, the presented design of the diffuser (100) when in an ambient temperature of 28 ° C, due to the frame structure with segments in the form of voids, provides an indicator of at least 21 ° C on the outer wall of the profiles (10) of the diffuser (100), compared with local 18 ° C of the analog shown in FIG. 7B.

The achieved temperature characteristics can significantly reduce the likelihood of condensation on the walls of the diffuser.

FIG. 8A - 8B, 9A - 9B show examples of models of slot diffusers (100, 200). In the upper part, each diffuser (100, 200) contains a decorative perforated metal sheet installed in the grooves (14, 24) of the profiles (10, 20). The diffuser (100, 200) is closed from the end parts with a plug, which is fixed with fasteners to the grooves of the profiles (10, 20).
