2. Description of the Related Art Conventionally, as a measure for preventing dew condensation on an air conditioning duct, that is, a heat insulating measure, a method has generally been adopted in which the outer surface of the duct is covered with a glass wheel. However, this method sacrifices flexibility when it is desired to give the conditioned air any directionality using a flexible duct. Further, the work of covering with a glass wool requires a great deal of skill and requires a considerable amount of construction time, and it was difficult to achieve an orderly finish, especially in the curved portion. As a duct for warm air blowing using non-woven fabric
No. 57360 is known, but this cannot efficiently manufacture an arbitrary length because a non-woven fabric strip is sushi-wound to form a tubular body. Furthermore, in addition to not having sufficient flexibility in terms of performance, there is a problem in that a tubular shape cannot be stably maintained without a reinforcing body. Japanese Utility Model Laid-Open Publication No. 54-79053 is known as a double pipe, but it cannot give a heat insulating effect to any pipe material, and when it has dew condensation because it does not have a fiber layer, it does not Cannot be dispersed. In addition, sound leakage has been regarded as a problem in conventional ventilation using an air conditioning duct in a karaoke box.

The non-woven fabric, the resin film or the metal foil, and the reinforcing wire material that form the strip forming the non-woven pipe of the present invention will be described. The non-woven fabric acts as a heat insulating material and soundproofing material due to its porous structure, and even when the surface temperature above the dew point cannot be secured, the generated dew condensation water is dispersed by the capillary phenomenon of the fibers and stored in the porous structure to prevent it from dripping. be able to. It is preferable to select one having a fine porous structure and / or a thick non-woven fabric layer because the heat insulating property and the soundproofing performance are improved. However, in the case of forming a bellows shape, the thickness may be limited depending on the physical properties of the non-woven fabric. Various materials can be selected as the fiber material constituting the non-woven fabric, and a function can be further added to the non-woven fabric tube depending on the fiber. For example, if a non-woven fabric composed of carbon fibers is used, a non-woven fabric tube having extremely low combustibility and good workability as compared with glass wool can be obtained. Further, by using a non-woven fabric partially mixed with low melting point fibers by a needle punching method or the like, a non-woven fabric tube which can be formed with slight heating can be obtained.

The resin film and / or the metal foil not only act as an air barrier layer on the wall surface of the non-woven fabric tube, but also prevent the non-woven fabric from expanding by laminating it on the non-woven fabric, which makes it possible to easily manufacture a stable non-woven fabric tube. . As the resin film, various thermoplastic synthetic resin films, and as the metal foil, various metal foils such as aluminum are used, but from the viewpoint of streamlining the spiral joining process, a resin film or a hot melt type adhesive is used. It is preferable to select a metal foil integrated with the film. When coating an arbitrary tubular body as a heat-insulating double tube, it is preferable to use only a metal foil or a laminate of a resin film and a metal foil for the purpose of reflecting heat rays radiated from an arbitrary tubular body that serves as an inner tube. preferable. It is preferable that the non-woven fabric and the film or metal foil are integrated by adhesion with various adhesives or heat fusion. In the present invention, air is blocked by the wall surface of the pipe as a technical problem, but it is also possible to blow out the conditioned air from any position of the pipe by intentionally making holes in the resin film and / or the metal foil.

The reinforcing wire has a function of stably holding the tubular shape. The material may be steel wire or synthetic resin, but one having high rigidity is preferable, and carbon steel wire is particularly preferable. Moreover, the cross-sectional shape is not particularly limited, and a circular shape, a rectangular shape, and a pipe shape can be considered. When the non-woven fabric layer is located on the outer surface of the tube, this reinforcing wire is preferably located between the strips because exposure of the non-woven fabric layer to the outer surface of the tube may cause dew condensation. It is better to locate it at.
