The present invention relates to a sound absorbing tube for preventing the noise between floors. The technical concept is that the floor noise generated in the multi-storey multi-storey floor in the ventilated and ventilated room air in the multi-family house is installed in apartments, villas and multi-family houses. In order to prevent direct communication through ventilation holes such as lower floor kitchens or toilets, a flexible duct communicating with an air duct is installed for each floor, and a sound absorbing member corresponding to a separate moisture resistant thermal insulation material is additionally installed at one side of the flexible duct to generate indoors. It relates to a flexible duct having a noise damping motor damper, characterized in that the noise is formed so as not to flow into the neighboring other furniture (upper or lower floor furniture).

In general, a dry air duct system (DRY AIR DUCT SYSTEM) is installed in apartment houses, such as apartments are formed to exhaust and vent the odor, polluted air, fire smoke, etc. generated in the interior of a multi-family kitchen, bathroom, and the like.

To this end, in the cavity (multi-storey) building, a dry granular air duct is installed on the one side line of the kitchen and bathroom side, and the flexible duct 3 is installed to connect the exhaust system to each floor.

In the conventional dry air duct system, as shown in FIG. 3, a vertical air duct (1: Air Duct) is installed in a vertical direction in a set construction passage of a building, and in particular, on one side or the other outer circumferential surface of the air duct separately. Saddle (4) of the installation is formed to be coupled to the flexible duct (3) of the kitchen or bathroom side for each floor, and the exhaust air perforated plate (5) is installed on the top floor (rooftop) of the air duct (1), An exhaust fan 6 is installed on the exhaust perforated plate 5 to exhaust the collected polluted air into the atmosphere.

However, such a conventional dry air duct system is connected to each floor of the apartment house to form an exhaust system, the noise generated by the neighboring upper and lower floors by a plurality of flexible ducts branched like branches from the central air duct Bars are directly transmitted through the kitchen or bathroom ventilation openings for each floor, which causes continuous noise exposure regardless of the separate floor soundproofing facility.

The present invention is to solve the conventional problems as described above, the technical gist of the construction is installed in apartments, villas, multi-family houses, etc. in the exhaust and ventilation of the indoor air of the multi-family of outside floor noise generated in the multi-storey multilayer or more Install flexible ducts that communicate with air ducts for each floor so as not to go directly through the ventilation openings of neighboring upper and lower kitchens or toilets, and on one side of the flexible ducts, additional sound absorbing members corresponding to separate moisture resistant thermal insulation materials are provided. It is an object of the present invention to provide a flexible duct having a noise damping motor damper, characterized in that the noise generated in the room is formed so as not to flow into the neighboring other furniture (upper or lower floor furniture).

The present invention for achieving the above object is installed on each floor kitchen or bathroom side of a multi-family multi-unit housing is connected to one end and the ceiling vent of the kitchen or bathroom to induce exhaust and ventilation of the indoor air and the other end In the flexible duct is vertically coupled to communicate with the granular air duct, the flexible duct is provided on one side end of the flexible duct, the main body 100 in the form of a pipe (PIPE) is formed on both sides; Sound absorbing material 200 is attached to the inner wall surface of the main body 100 is formed to absorb and sound-proof the interlayer noise that is directly through each floor kitchen or bathroom vents; It is made up.

At this time, the main body 100 filled with the sound absorbing material 200 is another embodiment, it is preferable that the flexible duct 3 is housed in one side and formed integrally.

Next, the present invention will be described in detail with reference to the accompanying drawings.

First, as shown in Figures 1 to 2, the present invention is generated in the room by separately laying the main body 100 attached to the sound absorbing material 200 on one side of the flexible duct (3) for ventilation of the kitchen or toilet connected at all times open. It is configured so that the noisy noise does not go directly to the other upper or lower furniture. Of course, the noise generated from the other furniture is formed to prevent the inflow into the kitchen and bathroom of the furniture.

The main body 100 is made of a pipe (PIPE) form the joint connection end is formed on both sides of the body.

That is, one joint connection end of the main body 100 is connected to the flexible duct 3, the other joint connection end is formed to be connected to the fire damper.

At this time, the sound absorbing material 200 is a kind of moisture-resistant heat insulating material is attached to the inside of the main body 100 with a thickness of about 1 ~ 2cm is formed to absorb sound between the floor interfacing directly through each floor kitchen or bathroom vents.

The sound absorbing material 130 is a sound wave transmitted radially on the pipeline in the interior of the main body 100 before the noise generated in the neighboring upper and lower living space through the air duct (1) into the flexible duct (3). It is formed to absorb.

Thus, the sound absorbing material 200 is preferably used as a porous sound absorbing material as an embodiment. That is, it is the most commonly used material in the construction or interior environment, and it is used by many companies because it is easy to handle and relatively inexpensive.

Such a porous sound absorbing material is classified into a 'glass fiber sound absorbing material', 'polyester sound absorbing material', 'polystyrene sound absorbing material', 'melamine sound absorbing material' and the like, and is preferably formed to use one type of sound absorbing material among the sound absorbing materials described above. .

At this time, the sound absorbing material 200 is formed to use a moisture resistant heat insulating material, such heat insulating material is generally a wall (壁 體) or a material that is hard to escape heat (전도) by conduction (복사) or radiation (輻射) It is used for ceiling to have anti-destructive and cold-proof effect. The materials include asbestos, rock wool, glass fiber, pearlite board, foam board of styrofoam, cork. Etc.

These thermal insulation materials enhance the thermal insulation efficiency in the flexible duct, eliminate gaps such as openings so that the heat inside the room does not leak to the outside or the heat from the outside, and greatly increase the thermal resistance of the structure itself. It is formed to.

That is, the heat loss is prevented from rising through the ventilation openings of the kitchen or the bathroom, and the sound generated in the indoor space is absorbed so as not to be transmitted between floors.

On the other hand, the main body 100 filled with the sound absorbing material 200 is another embodiment, it is preferable that the flexible duct (3) is housed in one side is formed integrally.

This is to induce the main body including the sound absorbing material (200) integrally formed by integrating the built-in flexible duct (3), so as to facilitate replacement and ease of work during installation and maintenance.

As described above, the present invention is to be installed in apartments, villas, multi-family houses, etc. to ventilate and ventilate the indoor air of multi-family to the outside. Install a flexible duct communicating with the air duct for each floor so as not to go through directly, but on one side of the flexible duct additional sound absorbing member corresponding to a separate moisture-resistant insulating material to the other furniture (the upper floor) Or lower floor furniture) is effective to prevent entry.
