Description

Has a sound purge function and one body type Flexible Duct the use is simple}

The present invention relates to an integrated flexible duct having a mute function and easy to use,

More specifically, the outer skin in the form of a film and the endothelial of breathable nonwoven fabric or woven fabric, or the inner skin of which artificially formed innumerable holes are simultaneously overlapped, spirally overlapping,

It is manufactured so that the space part is formed between the outer skin and the inner skin except the connection part fixed by the clip or heat fusion or adhesive, so that the sound of rupture of air flowing into the duct hose is introduced into the space part through the through hole, and it is extinguished with each other. To maximize the noise reduction effect,

It is made of nonwoven fabric, rubber foam, and polyurethane foam that are made by increasing specific gravity and thinning thickness without using any insulation material made of glass fiber which causes itching and is likely to be scattered when it comes into contact with the human body on the inner surface of the shell. The present invention relates to an easy-to-use flexible flexible duct with a mute function, which is excellent in noise reduction effect, maintaining cold and hot air temperature by insulation material, and also prevents dew condensation effect by simultaneously compressing and molding insulation material of predetermined width.

In general, the flexible duct is wound in a spirally overlapping fabric (1) in the form of a film (1a) cut to a predetermined width as shown in the accompanying drawings in Figure 1a overlapping both ends,

It is prepared by inserting the steel thread (2) in the overlapping portion of the both ends and then heat-sealed or attached with an adhesive.

However, the conventional flexible duct manufactured as described above has a problem in that the manufacturing is simple but there is no mute function, so that the bursting sound of air flowing into the duct hose is transmitted to the air outlet.

In order to remove the air rupture sound as shown in Figure 1b attached to the inner surface of the inner tube using a film-like fabric (1) perforated a myriad of holes (1b) on the surface and covered the outer shell (3) on the outer surface of the inner tube Flexible ducts of the form were created,

Such flexible ducts have to go through each working process of manufacturing the inner tube first and then covering the outer shell 3 on its outer surface, which is very cumbersome and time consuming, of course, the biggest problem is that In the case of the remaining portion after cutting the duct to a predetermined length, the inner tube and the outer shell 3 were separated, such that the storage and transportation were difficult, and thus recycling was not easy.

On the other hand, when looking at the flexible duct laid for the main purpose of insulation, as shown in Figure 1c of the accompanying drawings, the inner tube in which the steel thread (2) is first inserted into the heat-sealed connection of the fabric (1) in the form of a film (1a) It is made of a structure that wraps a thick insulating material (4) made of glass fiber on the outside thereof and covers the outer material (3) to the outer cover (3) to protect the insulating material (4).

Therefore, when manufacturing such flexible ducts, the inner pipe is also manufactured first, and then each of the operations of wrapping a thick heat insulating material 4 made of glass fiber on the outside thereof and covering the outer skin 3 on the outside of the heat insulating material 4. Since the process has to go through one by one, it is very cumbersome and time-consuming, as well as the thickness of the glass fiber insulation 4 is so thick that the overall volume is very large, difficult to install and occupy a very large space, thereby reducing the utilization of space.

In addition, when the glass fiber constituting the heat insulating material 4 during operation, there was a disadvantage that it causes tickling when in contact with the human body.

In addition, in the case of the remaining portion after cutting the duct to a predetermined length, a phenomenon such as separation of the inner tube and the heat insulating material 4 occurs separately, and it was not easy to recycle.

On the other hand, the flexible duct for the main purpose of the insulation has a problem that the burst sound of air flowing inside the inner tube is transmitted to the air outlet as it is without a mute function.

The present invention has been made in view of the above problems,

The simplified work process can significantly reduce the air burst noise (noise) flowing into the flexible duct,

When it comes into contact with the human body, it can cause tickling and use a special type of insulation material that minimizes specific gravity and thickness without using glass fiber that is likely to scatter. The temperature maintenance effect and condensation prevention effect of the warm air are increased, and the volume of the manufactured duct is very small, making it easy to store, distribute and install, and increase the utilization of space.

The purpose of the present invention is to provide a high-quality, flexible duct that can be easily recycled by cutting the duct to a predetermined length so that each component is not separated in any case.

Integral flexible duct having a mute function of the present invention and easy to use for achieving the above object is a film-like outer shell cut to a predetermined width, and

Spirally overlapping spirally overlapping one another selected from the film-like endothelium manufactured by drilling artificially numerous holes in the breathable nonwoven fabric or woven fabric or surface, at the same time,

At the same time as the space is formed between the outer skin and the inner skin, at the same time, the portions overlapping the two ends are gripped with a clip, or the steel or monofilament yarn is inserted in the overlapping portions, and then thermally fused or adhered with an adhesive.

It is characterized in that the space is formed in the entirety between the outer skin and the inner skin except for the clip or heat-sealed or adhesively fixed connection.

In addition, the integrated flexible duct having a mute function of the present invention and easy to use may be crimped after laminating a nonwoven fabric or a woven fabric having excellent insulation effect between the outer skin and the inner skin in multiple layers,

Or pressurize the rubber foam with excellent insulation and waterproof and air blocking (leakage prevention),

Alternatively, the polyurethane foam material having excellent insulation effect can be formed by pressurizing a polyurethane foam member having a high specific gravity and thinning thickness, and forming one of the insulation materials of a predetermined width in various ways to have an insulation effect for preserving the internal air temperature and preventing condensation. There is another feature in that it is done.

The integrated flexible duct having a mute function and easy to use according to the present invention has a space portion formed between the outer skin and the inner endothelium where the minute holes are formed except the clip or the heat-sealed or adhesive-connected joint, so that the air flows into the duct. The bursting sound is introduced into the space through the minute throughhole, and it is extinguished as it hits each other, so the noise reduction effect is very excellent.

On the other hand, the contact between the outer skin and the inner skin causes tickling and is not an insulating material manufactured using glass fibers that are likely to be scattered, but a non-woven fabric or a woven fabric laminated in multiple layers and then crimped or insulated. Pressurized rubber foam with excellent waterproofing and air blocking (leakage prevention) or polyurethane foam with excellent thermal insulation effect can be used in various ways to increase the specific gravity and make the thickness thinner. In the case of further formation, all of them have the advantage that the sound of rupture of the air flowing into the duct is introduced into the space part and absorbed and extinguished by each insulation when they are extinguished and extinguished.

In addition, the effect of maintaining the temperature of the cold and hot air is excellent due to the addition of the insulation effect, and the condensation prevention effect is also more excellent.

In addition, while using the insulation, the overall volume is small, so the space utilization is excellent, and the duct is cut to a predetermined length, which is convenient when connecting, and in the case of the remaining part after cutting and using, the endothelium and the insulation are separated separately as in the prior art. There are many advantages such as no recycling at all.
