도 3 은 본 발명에 의해 제조된 환기덕트의 사시도. 1 is a state diagram showing a conventional ventilation duct;
2 is a flow chart of a manufacturing process of a ventilation duct according to the present invention.
3 is a perspective view of a ventilation duct manufactured by the present invention;

본 발명인 덕트(2)는 아파트나 고층 빌딩 및 다가구 주택 등의 실내에 설치된 공조시스템에 연결되어 사용되는 것으로, 상기 덕트(2)는 실외쪽 벽체에 설치된 체임버와 실내측 전열교환기 및 디퓨져 등의 사이에 연결되어 사용된다.  The duct (2) of the present invention is used in connection with an air conditioning system installed in a room such as an apartment, a high-rise building and a multi-dwelling house. The duct (2) is connected between a chamber installed on the outdoor side wall, As shown in FIG.

상기 덕트(2)는 직사각형 모양의 관으로 형성되면서 중앙에 격벽이 수직으로 설치되어 통로를 분리 형성하고 있게 되며, 상기 덕트(2)의 외측 둘레면은 성형과정에서 금형을 통과하는 관계로 표면은 매끄럽고, 덕트(2)의 내면은 기포돌기(4)가 다수 형성되어 있어서 거친 형태를 하고 있게 된다. The duct 2 is formed as a rectangular tube and a partition is vertically installed at the center to separate the passages. The outer circumferential surface of the duct 2 passes through the mold during the molding process, And the inner surface of the duct 2 is formed into a rough shape by forming a large number of bubble protrusions 4. [

이때, 상기 기포돌기(4)로 인하여 덕트(2)의 무게는 가벼운 상태가 된다. At this time, due to the bubble protrusion 4, the weight of the duct 2 becomes light.

상기 덕트(2)의 제조과정을 도 2 에서 살펴보면, 먼저 시중에 널리 판매되어 일반적으로 사용되는 열가소성수지인 PVC, 가소제, 바이오세라믹, 발포제, 돌가루, 안정제 등을 배합기(6) 내부로 투입하게 되는데, 상기 재료의 투입 비율은 PVC 100 중량%에 대하여 가소제 1∼3 중량%, 바이오세라믹 3∼10 중량%, 발포제 1∼3 중량%, 돌가루 3∼5 중량%, 안정제 2∼8 중량%를 투입한다. Referring to FIG. 2, the manufacturing process of the duct 2 is as follows. First, PVC, a plasticizer, a bioceramic, a foaming agent, a stone powder, and a stabilizer, which are widely sold and commonly used thermoplastic resins, are put into the blender 6 The amount of the above materials is 1 to 3 wt% of plasticizer, 3 to 10 wt% of bioceramics, 1 to 3 wt% of foaming agent, 3 to 5 wt% of stone powder, 2 to 8 wt% of stabilizer, .

이때, 상기 바이오세라믹은 항균바이오세라믹으로 사용할 수 있다. At this time, the bioceramics can be used as antibacterial bio-ceramics.

그리고, 상기와 같은 배합비율은 상황에 따라 달리 할 수 있음으로 한정하지는 않으며, 상기 재료는 일반적으로 시중에 판매되는 것을 사용하고, 필요에 따라 다른 재료를 추가할 수 있음으로 배합재료를 한정하지 않는다. The compounding ratio is not limited to be different depending on the situation. The material is generally sold in the market, and other materials can be added as needed, so that the compounding material is not limited .

계속하여, 상기 배합기(6) 내부로 투입된 재료는 모터(8)의 동력으로 회전하는 교반기(10)에 의해 혼합되며, 이후로 혼합된 재료는 배합기(6)에서 호퍼(12)로 보내어지게 되고, 상기 호퍼(12)에서는 압출기(14)에 의해 혼합된 일부 재료가 가열부(16)로 보내어지게 된다. Subsequently, the material injected into the blender 6 is mixed by a rotating agitator 10 powered by the motor 8, and then the blended material is sent from the blender 6 to the hopper 12 In the hopper 12, a part of the material mixed by the extruder 14 is sent to the heating unit 16.

상기 가열부(16)에 도달한 재료는 170℃∼240℃로 가열되는 히터에 의해 젤(gel) 형태로 되면서 성형부(18)로 이동하게 되고, 상기 성형부(18)에서는 내부에 설치된 금형에 의해 재료가 덕트(2) 모양으로 성형 되면서 압출된다. The material that has reached the heating unit 16 is moved to the forming unit 18 in the form of a gel by a heater heated at 170 ° C. to 240 ° C. In the forming unit 18, The material is extruded while being molded into the shape of the duct 2.

이때, 성형 되면서 압출되는 덕트(2)는 금형을 통과하면서 외측면 둘레에 매끄러운 면이 형성되고, 상기 덕트(2)의 내부에는 발포제 의해 기포돌기(4)가 다수 형성되어 있게 된다. At this time, the duct 2, which is extruded while being molded, has a smooth surface around the outer surface while passing through the mold, and a large number of bubble protrusions 4 are formed inside the duct 2 by the foaming agent.

따라서, 상기 덕트(2)는 기포돌기(4)들에 의해서 무게가 경량화 되어 있게 된다. Therefore, the duct 2 is made to be light in weight by the bubble projections 4.

상기 이후로, 성형된 덕트(2)는 냉각부(20)에서 15℃의 물에 의해 냉각되어 고형화가 진행되고, 이후로 상기 덕트(2)가 냉각부(20)를 통과하여 외부로 이동하면, 상기 인출부(22)에서는 덕트(2)의 선단부를 클램핑 한 다음 전진 방향으로 당기게 되며, 이후로 절단부(24)에서 회전톱날이 덕트(2)의 일부를 규격화 된 사이즈로 절단하게 된다. After that, the formed duct 2 is cooled by the water of 15 ° C in the cooling part 20 and solidified, and then the duct 2 is moved to the outside through the cooling part 20 The leading end portion of the duct 2 is clamped in the drawing portion 22 and then pulled in the advancing direction. Thereafter, the cutting saw 24 cuts a part of the duct 2 into a standardized size.

상기 이후로, 절단된 덕트(2)는 반출부(26)에서 미 도시된 푸셔에 의해 수납박스로 낙하되면 작업자가 수거하여 포장하게 된다. After that, the cut duct 2 is dropped by the pusher (not shown) in the take-out unit 26 to the housing box, and the worker collects the duct 2 and packs it.

상기와 같은 제조과정으로 생산된 덕트(2)는 발포제를 이용하여 기포돌기(4)를 다수 형성하는 방식인 관계로, 무게의 경량화에 따른 덕트(2)의 가격 저렴화로 가격 경쟁력이 향상되고, 또한 운반 및 조립이 용이하여 작업의 편리성이 향상 되면서, 작업시간 단축에 따른 인건비 등이 감소되는 효과가 있다. Since the duct 2 produced by the above-described manufacturing process forms a large number of the bubble protrusions 4 using the foaming agent, the cost competitiveness is improved due to the reduction of the cost of the duct 2 due to the weight reduction, In addition, it is easy to carry and assemble to improve the convenience of the work, and the labor cost due to the shortening of the working time is reduced.

상기와 같은 본 발명의 바람직한 실시 예를 첨부된 도면에 의하여 상세히 설명하였지만, 본 발명은 여기에 기재된 실시 예에 한정되는 것이 아니고, 이 기술 분야에서 통상의 지식을 가진 당업자라면 본 발명의 기술적 사상 및 범위를 벗어나지 않는 범위 내에서 다양하게 수정 및 변형할 수 있을 것이다.
