DETAILED DESCRIPTION OF THE INVENTION

[0032] As seen in the FIGURE, the flexible ventilation duct of the invention comprises of an inner layer (1) forming a tubular inner volume to direct the conditioned air to an environment to be climatized from a main air duct, and an insulation layer (2) and an outer layer (3) enabling the insulation of conditioned air. The said invention is obtained by laminating the inner layer (1) and the outer layer (2) on top of each other such that an insulation material (3) stays between strip plates formed of at least one or more of aluminum PET, polyester, metalized OPP, metalized polyester and/or PVC. The mentioned inner and outer layers (1 and 2) comprise at least one insulation material (3) laminated so as to form an inseparable entirety therebetween, and steel wire (4) enabling the formed structure to maintain its cylindrical tubular shape and to have a flexible structure. Steel wire (4) spirally wound to the inner structure during production provides both shape and flexibility to the ventilation duct. At the same time, as the insulation layer (3) is comprised of more than one insulation materials, it enables the structure to maintain its flexibility. As seen in the FIGURE, additional insulation materials (3) may be added to the production process according to the desired amount and type of insulation in the inner part of the flexible ventilation duct (20) of the invention. Due to the production method of the invention, all kinds of insulation materials, such as rubber, polyethylene liners, polyester fibers, etc. are used as insulation materials. Thus, the flexible ventilation duct (20) of the invention, comprising all of the inner, outer and insulation layers (1, 2 and 3) at once and the steel wire (4) during production, and obtaining a holistic structure as a result of production is obtained.

[0033] A flexible ventilation duct (20) may be produced, which is of a holistic, single piece structure inseparably laminated due to chemicals applied therebetween by winding an inner layer (1) using strip plates in the form of at least one or more of aluminum PET, polyester, metalized OPP, metalized polyester and/or PVC; an insulation layer (3), steel wire (4) and an outer layer (2) using at least one or more of aluminum PET, polyester, metalized OPP, metalized polyester and/or PVC as in the mentioned inner layer (1) onto a rotary, cylindrical shaft (10). The insulation layer (3) may comprise the same or different kinds of insulation materials (3) of one or more layers in a desired thickness. This is a very important factor providing flexibility to the insulation layer (3). If the insulation layer (3) is not flexible, it is not possible to speak of the flexibility of insulated flexible ventilation ducts. As the present invention is of a holistic structure, it is not necessary to attach it to the main ventilation duct as in the prior art. It may be readily assembled to the main ventilation duct in one go with the brackets and band from the outermost part. This situation saves a substantial amount of time and provides major advantages compared to prior art products by reducing the costs of labor necessary for assembly, and also provides a form of assembly which is of higher quality.

[0034] The holistic structure obtained due to the production process applied in the present invention does not allow the air directed from the main ventilation duct to come in contact with the insulation layer of the insulated flexible ventilation duct in any way. Additionally, as different materials with better insulation and hygiene properties which are an alternative to glass wool and are one of the advantages provided by the production method may be used as insulation materials, factors which may damage human health are eliminated. Checking after the assembly is not necessary. As it is may be readily understood whether it is connected to the main ventilation duct with the method of checking by looking from the outside. Less heat loss occurs in the present invention as the outside diameter is less compared to the others. Additionally as the insulation material is completely laminated, there is no air circulation between the inner layer (1), insulation layer (3) and outer layer (2) in the holistic structure. This situation enables there to be much less heat loss.

[0035] Possible wearing and tearing which may occur because of the completely laminated production process of the invention remain in a local region and do not cause air circulation. Thus, there is no distortion in the structure of the duct. Thus, there is no distortion in the structure of the insulation layer (3) either, and does not cause any allergic affect.

[0036] As the outside diameter of the present invention is less compared to other flexible ventilation ducts, it is easier to be applied even in narrow areas. Additionally, it provides a substantial transportation advantage as it takes up less volume. It eliminates all of the adverse effects which other flexible ventilation ducts create. Acoustic insulation is easier in the present art. A barrier layer is additionally applied around the inner pipe to provide acoustic insulation in the prior art. However, rubber being one of the insulation materials used in the present art has acoustic insulation by its own nature. Thus, an additional layer is required for acoustic insulation.

[0037] As a result, a holistic, completely laminated flexible ventilation duct, which may be assembled at one go, i.e. without requiring another additional process after production is obtained. Thus, it provides many advantages not put forward in the prior art such as being hygienic, being of high insulation quality, having high thermal performance, having various materials, being non-dust-forming, being easy to assemble, not being affected by dampness, being environmentally friendly, being non-allergenic, having a transportation advantage and being able to be applied in a narrow area.
