Description

DETACHABLE AND REMOVABLE DISCHARGE PART VARIABLE AIR VOLUME LINEAR DIFFUSER AND METHOD FOR CONSTRUCTING THE SAME
The present invention relates to a detachable and removable discharge part variable air volume linear diffuser and a method for constructing the same, and more particularly, to a detachable and removable discharge part variable air volume linear diffuser and a method for constructing the same that provide many conveniences in the construction and enhance the outer appearance in the interior design.
Large-sized buildings constructed recently, such as, office, factory, retail shop, department store and residential apartment are facilitated with air conditioning systems like air cooling/heating devices or/and air ventilation devices so as to maintain indoor air to a fresh and comfortable state. In this case, the air-conditioned air (heated/cooled air or fresh air) through the air cooling/heating devices or air ventilation devices is conveyed to a given indoor location through air duct, without direct exposure to open space, and after that, the air is diffused and discharged by means of an air diffuser disposed on the end of the air duct.
The air handler unit, which is installed in the building to supply air to indoor space, filters indoor contaminated air, adds/distracts heats from outdoor air, and applies appropriate humidity to the finally discharged air.
As mentioned above, the conditions (temperature, humidity and cleaning state) of air are usefully controlled by means of the air handler, and the conditioned air flows to the inside of the building through duct work and finally through air diffuser.
The body portion of air diffuser configured wherein the end portion of the duct is preferred not to be seen from occupant space, thus allowing the outer appearance of the interior design of the ceiling to be more improved.
According to the installation types and purposes of air diffusers, on the other hand, they are divided into square type diffusers discharging air to four directions and linear diffusers enhancing the outer appearance in the interior design.
Hereinafter, an explanation on the installation configuration of a variable air volume linear diffuser in conventional practice will be given with reference to FIG.1.
First, a ceiling structure of a building is constructed.
A plurality of carrying bars 10 are disposed in the form of a lattice in such a manner as to traverse the interior of the ceiling, and fixing clips 30 are screw-coupled to the carrying bars 10 so as to fix T-bars 20 thereto.
A pair of T-bars 20 is lockedly fixed to the fixing clips 30, while having a given distance there between.
If the ceiling structure is constructed, a variable air volume linear diffuser D is installed on the constructed structure.
The lower portion of the variable air volume linear diffuser D is seated between the pair of T-bars 20, and the upper portion thereof is fixed to the ceiling structure by means of wires or welding, so that as shown in FIG.1, the variable air volume linear diffuser D is constructed on the ceiling structure.
However, the conventional method for constructing the variable air volume linear diffuser has the following problems:
Firstly, the construction of the ceiling structure is conducted separately from the construction of the variable air volume linear diffuser, thus increasing the number of work processes, delaying the period of construction, raising the construction cost, and lowering the work efficiencies.
That is, the chamber of the variable air volume linear diffuser and a discharge part through which air is discharged from the chamber are formed integrally with each other, so that the construction of the variable air volume linear diffuser is made separately from the construction of the ceiling structure. Further, the construction materials for the ceiling structure necessarily include the T-bars 20 supporting the integral type variable air volume linear diffuser, thus making it hard to reduce the construction cost.
Secondly, a different feeling is caused by different materials between the T-bars 20 and the discharge part of the variable air volume linear diffuser D, thus spoiling the outer appearance in the interior design of the ceiling.
That is, in view of recent trend wherein it is important to achieve both of the stability in the construction of the structure and the design in the outer appearance thereof, the outer appearance in the interior design of the ceiling may be spoiled due to the overlapping lines and the different feeling in materials between the T-bars 20 and the discharge part of the variable air volume linear diffuser.
Accordingly, the present invention has been made in view of the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a detachable and removable discharge part variable air volume linear diffuser that is configured wherein discharge bars and a chamber are disposed separately from each other to allow the discharge bars exposed indoors to be easily designed without having any different feeling from a ceiling structure, thus optimizing the outer appearance in the interior design of the ceiling.
It is another object of the present invention to provide a method for constructing a detachable and removable discharge part variable air volume linear diffuser that is configured wherein discharge bars serve as structures of a ceiling to allow the construction of the structure and the construction of the diffuser to be conducted together, thus reducing the number of work processes and shortening the period of construction.
To accomplish the above-mentioned objects, according to a first aspect of the present invention, there is provided a detachable and removable discharge part variable air volume linear diffuser constructed on a ceiling having a plurality of carrying bars mounted thereon and a pair of fixing clips fitted to each carrying bar in a longitudinal direction of the carrying bar, the linear diffuser including: an adapter lockedly coupled to the pair of fixing clips on both sides thereof under the carrying bar and having coupling portions formed on the lower portion thereof; a plurality of discharge bars coupled to the coupling portions of the adapter in such a manner as to be spaced apart from each other to form discharge holes penetrated up and down; sealing members made of soft materials and coupled to the top surface of the discharge bars in longitudinal directions of the discharge bars; a chamber coupled to the discharge bars in such a manner as to be brought into contact with the sealing members and having an inlet formed on one side thereof to introduce air whose temperature is controlled thereinto, an outlet formed on the other side facing the discharge bars to discharge the air introduced into the inlet therefrom, and partitioning members disposed on the outlet to partition the outlet into a plurality of portions corresponding to the discharge holes; and opening/closing blades hinge-coupled to the partitioning members to open and close the partitioned outlet.

According to the present invention, the detachable and removable discharge part variable air volume linear diffuser and the method for constructing the same have the following advantages:
Firstly, the detachable and removable discharge part variable air volume linear diffuser has the chamber and the discharge bars disposed separately from each other, thus enhancing the conveniences in the construction of the ceiling.
That is, the discharge bars form the passages through which air is discharged from the chamber and serve as the structures for a ceiling, for example, T-bars, so that the construction of the discharge bars and the construction of the ceiling structures are conducted at the same time, thus reducing the number of work processes to enhance the conveniences in the construction of the ceiling and reducing the period of construction and the construction cost to provide many economical advantages.
Secondly, no overlapping between the discharge bars and the construction structures is generated, thus enhancing the outer appearance in the interior design of the ceiling.
That is, in the conventional practice, the T-bars as the structures for installing the integral type variable air volume linear diffuser to the ceiling are overlapped with the discharge part of the diffuser, thus making it hard to enhance the outer appearance in the interior design of the ceiling. Due to the different feeling caused by different materials between the T-bars and the discharge part of the variable air volume linear diffuser, further, it is difficult to optimize the outer appearance in the interior design of the ceiling. According to the present invention, however, the discharge bars serve as the T-bars to prove high quality of interior design of the ceiling.
Accordingly, the detachable and removable discharge part variable air volume linear diffuser and the method for constructing the same provide many conveniences in the construction and enhance the outer appearance in the interior design of the ceiling.

Before the present invention is disclosed and described, it is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting. Therefore, the terminology used herein should be interpreted as the meaning and concept confirming the technological scope of the present invention so as to explain the present invention in the best way.
Hereinafter, an explanation on a detachable and removable discharge part variable air volume linear diffuser according to the present invention will be in detail given with reference to FIGS.2 to 5.
According to the present invention, a detachable and removable discharge part variable air volume linear diffuser has a chamber and discharge bars separable from each other.
As a result, the detachable and removable discharge part variable air volume linear diffuser according to the present invention can provide many conveniences in the construction of a ceiling and enhance the outer appearance in the interior design of the ceiling.
As shown, the detachable and removable discharge part variable air volume linear diffuser includes an adapter 100, discharge bars 200, sealing members 300, a chamber 400, opening/closing blades 500 and connection plates 600.
The adapter 100 serves as a connector connecting the discharge bars 200 and the chamber 400 with each other.
As shown in FIG.4, the upper portion of the adapter 100 is coupled to fixing clips 30 coupled to a carrying bar 10, and the lower portion of the adapter 100 is coupled to the discharge bars 200.
At this time, each fixing clip 30 has an upwardly bent fixing portion 31 formed on the lower portion thereof, and the adapter 100 has downwardly bent locking grooves 110 formed on both sides of the upper portion thereof.
Under the above-mentioned configuration, the adapter 100 is lockedly fixed to the fixing clips 30.
Further, the adapter 100 has a coupling portion 120 formed on the lower portion thereof in such a manner as to slidingly couple the discharge bars 200 thereto.
Next, the discharge bars 200 serve as guides for discharging the air discharged from the chamber 400 to indoors through a ceiling, and as mentioned above, the discharge bars 200 are coupled to the adapter 100.
The discharge bars 200 are spaced apart from each other in such a manner as to form discharge holes 210 penetrated up and down among them.
Desirably, each discharge bar 200 has a roundedly curved surface PART on one side thereof to obtain the Coanda effect.
On the other hand, desirably, the end portions of the outermost discharge bars 200 are extended outward to form seating pieces 220.
The extended length of the seating pieces 220 is larger than the width of the adapter 100 in such a manner as to seat finishing members P as will be discussed later thereonto.
As the seating pieces 220 are formed to fix the finishing members P to the discharge bars 200, like this, the existing building structures, for example, T-bars, for supporting the finishing members P can be removed.
On the other hand, each discharge bar 200 is divided into a supply portion S and a return portion R. The supply portion S onto which the chamber 400 is seated serves to discharge the air in the chamber 400 to the indoors, and the return portion R is connected to the supply portion S so as to mount the finishing members P and to conduct the interior design of the ceiling, irrespective of the mounting of the chamber 400 thereon.
The length of the supply portion S of each discharge bar 400 is equal to the length of the chamber 400, and the length of the return portion R is determined in accordance with the size of the ceiling.
Next, the sealing members 300 serve to have a shock-absorbing function and an air tightness function in the process where the chamber 400 and the discharge bars 200 are coupled to each other.
Each sealing member 300 is located on the corresponding discharge bar 200 (the supply portion S) onto which the chamber 400 is seated in the longitudinal direction of the discharge bar 200.
Each sealing member 300 has a sealing groove 310 upwardly open toward the chamber 400.
The sealing members 300 are not limited in the materials thereof, but desirably, they may be made of soft materials.
Next, the chamber 400 serves to discharge the air whose temperature is controlled through a central system to the indoors, and the chamber 400 is coupled to the discharge bars 200.
The chamber 400 has an inlet 410 and an outlet 420 formed on one side thereof and on the other side thereof.
The inlet 410 is a through hole into which air is introduced from a duct, and the outlet 420 is a through hole from which the air introduced through the inlet 410 is discharged to the discharge bars 200.
The outlet 420 is of course formed toward the discharge bars 200 located under the chamber 400.
At this time, partitioning members 430 are disposed on the outlet 420 so as to partition the outlet 420 into a plurality of portions.
The number of partitioning members 430 is equal to the number of discharge bars 200, and the space between the neighboring partitioning members 430 is equal to the size of the discharge hole 210 formed between the neighboring discharge bars 200.
Coupling protrusions 431 are extended downward from both sides of the chamber 400 forming the outlet 420 and from the center partitioning member 430.
When the chamber 400 is seated onto the sealing members 300, the coupling protrusions 431 are inserted into the sealing grooves 310 to optimize air tightness and coupling force between the chamber 400 and the discharge bars 200.
On the other hand, the chamber 400 senses an air temperature and a room temperature through temperature sensors and automatically opens and closes the opening and closing blades 500 as will be discussed later, thus allowing the air to be discharged.
The operating principles of the temperature sensors and the opening and closing blades 500 are the same as those in the existing technology, and therefore, an explanation on them will be avoided for the brevity of the description.
Next, the opening and closing blades 500 open and close the outlet 420 of the chamber 400, and as shown in FIG.3, they are hinge-coupled to the partitioning members 430.
The opening and closing blades 500 rotate around the hinge portions in such a manner as to be brought into contact with the adjacent partitioning members 430 or to be separated from the adjacent partitioning members 430, thus closing or opening the outlet 420.
Further, as shown in FIGS.3 and 5, each opening and closing blade 500 has a distance maintaining member 510 mounted thereon.
The distance maintaining members 510 serve to prevent the opening and closing blades 500 from completely closing the outlet 420, and even if the operation of the diffuser stops according to seasons, accordingly, a portion of the outlet 420 of the chamber 400 is open to ventilate indoor air.
The distance maintaining members 510 are fixedly protruding from the opening and closing blades 500 and not limited any specific materials.
The distance maintaining members 510 are fixed to the opening and closing blades 500 in the longitudinal directions of the opening and closing blades 500, that is, in the longitudinal direction of the chamber 400, in such a manner as to be spaced apart from each other.
Under the above-mentioned configuration, even if the opening and closing blades 500 are brought into close contact with the adjacent partitioning members 430, the outlet 420 is open by the protruding lengths of the distance maintaining members 510 from the opening and closing blades 500.
Next, the connection plates 600 serve to connect the discharge bars 200 and neighboring discharge bars 200 and are desirably formed of metal plates.
When the discharge bars 200 are located on the ceiling, they are connected serially to neighboring discharge bars 200, and in this case, the connection plates 600 serve to fix the side surface of the discharge bars 200 thereto to connect the discharge bars 200 and neighboring discharge bars 200.
In more detail, as shown in FIG.4, the connection plates 600 come into close contact with the side surface of the neighboring adapters 100, and they are fixed to the adapters 100 by means of fastening means like screws, pieces and so on, thus connecting the discharge bars 200 and neighboring discharge bars 200.
Hereinafter, an explanation on a method for constructing the detachable and removable discharge part variable air volume linear diffuser according to the present invention will be given with reference to FIGS.6 and 7.
First, carrying bars 10 are mounted to construct a ceiling structure (at step S100).
The carrying bars 10 constitute the frames of the ceiling structure in such a manner as to be disposed traversely on a ceiling slab.
At this time, the carrying bars 10 are fixedly suspended from hanger bolts fixed to the ceiling slab, and the fixing clips 30 are fitted to the carrying bars 10.
The fixing clips 30 serve to couple the adapter 100 thereto, and a pair of fixing clips 30 is provided for one diffuser.
At this time, the distance between the pair of fixing clips 30 is equal to the width of the adapter 100.
Next, the discharge bars 200 and the adapter 100 are coupled to each other (at step S200).
That is, the discharge bars 200 are passages through which air is discharged from the ceiling, and they are coupled by means of the adapters 100 to the length corresponding to the width of the ceiling.
As mentioned above, each discharge bar 200 is divided into the supply portion S and the return portion R, and the discharge bars 200 are coupled by means of the adapter 100 in such a manner as to alternately locate the supply portions S and the return portions R in accordance with the location of the chamber 400 designed.
Next, the discharge bars 200 coupled by the adapter 100 are coupled to the carrying bars 10 constructed on the ceiling slab (at step S300).
In more detail, the fixing portions 31 of the fixing clips 30 fitted to the carrying bar 10 are locked onto the locking grooves 110 of the adapter 100.
Accordingly, as shown in FIG.3, the adapter 100 is suspended supportedly from the fixing clips 30 on both sides thereof.
Of course, it can be understood that the discharge bars 200 are located in a vertical direction with respect to the carrying bar 10.
On the other hand, the adapter 100 suspended from the carrying bar 10 serves to continuously arrange the discharge bars 200 on the ceiling, and next, the continuously disposed discharge bars 200 are fixed by the worker.
That is, the connection plates 600 are brought into contact with the side surface of the neighboring adapters 100 and fixed to the adapters 100 by means of fastening means like pieces to prevent the discharge bars 200 from being separated from neighboring discharge bars 200.
Accordingly, the mounting of the discharge bars 200 onto the carrying bar 10 is finished.
As appreciated from the foregoing, the discharge bars 200 constitute a portion of the diffuser, but they are constructed together with the ceiling structure, thus enhancing the conveniences of the work, shortening the period of construction, and improving working efficiencies.
Next, the chamber 400 is seated onto the discharge bars 200 (at step S400).
In more detail, the outlet 420 of the chamber 400 is seated correspondingly onto the supply portions S of the discharge bars 200.
At this time, the coupling protrusions 431 extended from both sides of the outlet 420 of the chamber 400 and from the center partitioning member 430 are inserted into the sealing grooves 310 of the sealing members 300 mounted on the top surface of the discharge bars 200, and the number of the partitioned portions of the outlet 420 corresponds to the number of discharge holes 210 of the discharge bars 200.
Next, the discharge bars 200 and the chamber 400 are coupled to each other by means of fastening means like bolts.
At this time, the coupling protrusions 431 of the chamber 400 and the sealing members 300 are brought more rigidly into contact with each other, thus maintaining air tight state.
After that, the finishing members P are seated onto the seating pieces 220 of the discharge bars 200 located at the outermost portion and fixed thereto by means of fastening means, so that as shown in FIG.7, the construction of both of the detachable and removable discharge part variable air volume linear diffuser and the ceiling is finished (at step S500).
As mentioned above, the detachable and removable discharge part variable air volume linear diffuser and the method for construction the same according to the present invention have the discharge bars mounted separately therefrom, so that upon the construction of a ceiling structure, the discharge bars form a portion of the ceiling structure.
Accordingly, the detachable and removable discharge part variable air volume linear diffuser and the method for construction the same according to the present invention can improve the conveniences in the construction of the ceiling structure and optimize the outer appearance in the interior design of the ceiling.
While the present invention has been described with reference to the particular illustrative embodiments, it is not to be restricted by the embodiments but only by the appended claims. It is to be appreciated that those skilled in the art can change or modify the embodiments without departing from the scope and spirit of the present invention.
