본 발명은 대류현상이 쉽게 일어나지 않는 대공간에 대하여 내부 기류(공기)를 강제적으로 순환시킬 수 있도록 하는 제트팬 또는 기류 순환장치의 팬모터 십자형 고정익(또는 팬모터 고정브라켓)의 단부에 결합되되, 임펠러의 회전에 의한 기류의 와류를 방지하면서 직선으로 멀리까지 기류로 배기시킬 수 있도록 하는 허브가이드에 관한 것으로, 상기 허브가이드는 구동모터의 후미에 꼬깔형 구조의 콘을 갖는 십자형 고정익이 결합되어 대공간에 대한 냉난방시 적은 동력만으로도 기류를 원활하게 순환시킬 수 있도록 형성되어 에너지 절약을 도모함은 물론 가동 생산성과 효율성이 크게 향상되는 것을 특징으로 하는 와류방지 및 기류 직선화 유도용 십자형 고정익 콘을 갖는 허브가이드에 관한 것이다.
The present invention is coupled to the end of the fan motor cross-shaped fixed blade (or fan motor fixing bracket) of the jet fan or air flow circulator to forcibly circulate the internal air (air) for a large space where convection is not easily occur, It relates to a hub guide that can be exhausted to the air flow in a straight line to prevent the vortex of the air flow by the rotation of the impeller, the hub guide is a large space is combined with a cross-shaped fixed blade having a cone-shaped cone to the rear of the drive motor It is designed to circulate airflow smoothly with only a little power during heating and cooling. Therefore, it is possible to save energy and to improve the productivity and efficiency of operation. It is about.

일반적으로 강당, 체육관, 대형마트, 공장 등과 같은 대공간에서는 내부 공기를 대류 순환시켜 쾌적한 실내 환경을 조성하도록 공조시스템이 형성되거나, 천정 등에 기류 순환장치 또는 제트팬이 구비되고 있는 실정이다.In general, in large spaces such as auditoriums, gymnasiums, large marts, and factories, air conditioning systems are formed to convection circulate internal air to create a comfortable indoor environment, or airflow circulators or jet fans are provided on the ceilings.

이러한 공조시스템의 공조기는 건물이나 지하시설 등에 설치되어 냉난방 기능뿐만 아니라 공기정화 기능을 부여하는 것이 거의 필수적인 것으로 인식되고 있는 실정이다.An air conditioner of such an air conditioning system is installed in a building or an underground facility, and it is recognized that it is almost essential to provide not only an air conditioning function but also an air purifying function.

또한, 공조기를 통한 냉난방 기류는 공조덕트를 통하여 건축물의 각 실내로 분기되며, 각 실내로 분기된 기류는 각 실내의 공기 취출구를 통하여 실내 냉난방 및 환기의 기능을 수행하게 된다.In addition, the air-conditioning and airflow through the air conditioner is branched to each interior of the building through the air conditioning duct, the airflow branched to each room performs the function of indoor cooling and heating and ventilation through the air outlet of each room.

한편, 종래의 기류 순환장치 또는 제트팬은 대공간과 같이 층고가 높고 공간이 넓은 경우 취출된 냉난방 기류가 원하는 공조영역으로 충분히 도달되지 못하고 실내의 상층부로 급속하게 상승해 체류되어 지붕으로 열 손실이 크고 상하 온도 차가 크게 됨으로써 건축물의 예열시간이 길고 유지되어야 하는 문제가 발생되고 있다.On the other hand, conventional airflow circulators or jet fans have high floor heights and large spaces, such as large spaces. As a large and vertical temperature difference becomes large, the preheating time of a building is long and the problem which should be maintained arises.

결국, 종래의 기류 순환장치 또는 제트팬은 이에 따른 장비용량이 증대되어야 하며, 각 구역(ZONE)에 따라 부분적으로 기류속도 및 도달거리, 풍량, 방향 등의 조절이 거의 불가능하여 공조기 및 열원설비를 가동하여도 설계조건에 맞는 냉난방 온도 및 기류를 얻을 수 없어서, 이로 인한 막대한 에너지 손실과 설비투자에 따른 금전적 손실이 발생되고 있는 실정이다.As a result, the conventional airflow circulator or jet fan has to increase the equipment capacity accordingly, and it is almost impossible to control the airflow speed, reach, air volume, direction, etc. according to each zone. Even if it is operated, it is impossible to obtain cooling and heating temperatures and airflows suitable for the design conditions, which causes huge energy loss and financial loss due to facility investment.

그리고 종래의 기류 순환장치 또는 제트팬 장치의 경우에는 원통 형상의 하우징 내부에 장착된 임펠러(Impeller)가 회전되는 축류형 팬으로 형성되고, 상기 임펠러가 회전 운동을 하게 되면 하우징에 유입된 공기는 임펠러의 회전 방향을 따라 회전하면서 하우징 내부에서 와류를 일으키면서 진행하게 된다.In the case of a conventional airflow circulation device or a jet fan device, an impeller mounted in a cylindrical housing is formed as an axial flow fan in which the impeller is rotated. When the impeller rotates, the air introduced into the housing is impeller. While rotating along the rotational direction of the vortex is caused to proceed in the housing.

이때, 임펠러가 일정한 회전수로 회전하게 되면 임펠러의 선속도의 크기는 임펠러의 회전축에서 가장 작고 원주 둘레로 갈수록 반지름에 비례하여 증가된다.At this time, when the impeller rotates at a constant rotation speed, the magnitude of the linear velocity of the impeller is the smallest in the rotation axis of the impeller and increases in proportion to the radius around the circumference.

따라서, 상기 임펠러를 통과하는 공기는 임펠러의 선속도의 크기에 직접적인 영향을 받으므로 중심에서의 회전성분이 가장 작고 원주 둘레로 갈수록 회전 성분의 크기와 통과 유량이 증가하게 된다.Therefore, since the air passing through the impeller is directly affected by the magnitude of the linear velocity of the impeller, the rotational component at the center is the smallest, and the size and the flow rate of the rotational component are increased as the circumference becomes smaller.

그러나 종래의 기류 순환장치 또는 제트팬에는 임펠러를 통과한 공기의 회전 성분을 직선 성분으로 변화시키는 구조가 장착되어 있지 않거나 장착되어 있다 하더라도 모터십자형 고정익(또는 모터고정브라켓)과 직선화장치(가칭) 별도로 분리되어 있어 임펠러를 통과한 공기는 임펠러에 의해 속도는 증가되지만 회전 성분에 의해 와류가 발생되어 직진력이 상쇄하게 된다.However, even if the conventional airflow circulator or jet fan is not equipped with or has a structure for changing the rotational component of the air passing through the impeller into a linear component, the motor cross type fixed blade (or motor fixing bracket) and the linearizer (tentative name) are separately provided. The air passing through the impeller is separated and the speed is increased by the impeller, but the vortices are generated by the rotating component to cancel the straight force.

결과적으로 상기 하우징 내부에서 공기의 회전에 의해 발생하는 와류는 공기의 내부 에너지를 상쇄시켜 공기가 직진 방향으로 이동하려는 직진 방향 운동에너지가 줄어들기 때문에 하우징에서 배출된 기류가 원거리까지 도달하기 못하고 사방으로 퍼지며 속도가 급격히 낮아지는 문제가 있다.
As a result, the vortex generated by the rotation of the air inside the housing cancels the internal energy of the air and reduces the kinetic energy in the linear direction in which the air moves in the straight direction. There is a problem that the speed is rapidly lowered.

본 발명은 상술한 문제점을 해결하기 위한 것으로, 그 기술적 요지는 대류현상이 쉽게 일어나지 않는 대공간에 대하여 내부 기류(공기)를 강제적으로 순환시킬 수 있도록 하는 제트팬 또는 기류 순환장치의 팬모터 십자형 고정익(또는 팬모터 고정브라켓)측 단부에 결합되되, 임펠러의 회전에 의한 기류의 와류 및 후미의 기류 공동 구간에 의한 와류를 방지하면서 직선으로 멀리까지 기류로 배기시킬 수 있도록 하는 허브가이드에 관한 것으로, 상기 허브가이드는 구동모터의 후미에 기류의 회전성분을 직진성분으로 바꾸어주는 가이드와 가이드의 모터 후미측 중심에 직선꼬깔형 구조를 갖는 콘 형태가 결합된 형상의 십자형 고정익에 결합되어 대공간에 대한 냉난방시 적은 동력만으로도 기류를 원활하게 순환시킬 수 있도록 형성되어 에너지 절약을 도모함은 물론 가동 생산성과 효율성이 크게 향상되는 것을 특징으로 한다. 와류방지 및 기류 직선화 유도용 십자형 고정익 콘을 갖는 허브가이드를 제공함에 그 목적이 있다.

다음은 첨부된 도면을 참조하며 본 발명을 보다 상세히 설명하겠다.DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings.

먼저 도 1 내지 도 7에 도시된 바와 같이, 본 발명의 허브가이드는 크게 팬모터 하우징과 십자형 고정익으로 구성되되, 상기 팬모터 하우징과 십자형 고정익은 서로 결합되어 일체성을 확보하도록 형성된다.First, as shown in FIGS. 1 to 7, the hub guide of the present invention is largely composed of a fan motor housing and a cross fixed blade, and the fan motor housing and the cross fixed blade are coupled to each other to ensure integrity.

이에, 상기 팬모터 하우징(100)은 일측에 조립용 플랜지가 형성되고 내부에 임펠러를 갖는 구동모터(110)가 형성된다.Thus, the fan motor housing 100 has a flange for assembly is formed on one side and a drive motor 110 having an impeller therein is formed.

이때, 상기 구동모터는 십자형 고정익와 사방 외주면이 일부 지지되면서 고정되도록 하되, 상기 구동모터의 후미에는 팬모터 하우징의 십자형 고정익(120)으로부터 연장되어 결합된 허브가이드(200)가 형성된다.At this time, the drive motor is to be fixed while the cross-shaped fixed blade and all four outer peripheral surface is fixed, the hub guide 200 is extended from the cross-shaped fixed blade 120 of the fan motor housing is coupled to the rear of the drive motor.

이때, 상기 허브가이드(200)는 구동모터의 후미 측과 맞닿는 단부에 기류가 진행하는 방향에 따라 각이 좁아지는 각뿔 또는 원뿔 형태의 콘(210)이 형성되어 임펠러의 회전에 의한 와류 및 모터 후미의 기류 공동 구간에 의한 와류를 방지하면서 직선 기류로 배기시킬 수 있도록 형성된다.At this time, the hub guide 200 is formed at the end of the contact with the rear end of the drive motor is formed a cone 210 of a pyramid or cone shape that narrows the angle according to the direction of the air flow proceeds, so that the vortex and the motor tail by the rotation of the impeller It is formed to be exhausted by a straight air stream while preventing the vortex caused by the air flow cavity section of the.

다시 말해, 구동모터의 회전에 의해 임펠러가 회전하면 기류는 회전방향 즉, 원주방향으로 회전하면서 와류를 일으키게 되고, 이렇게 와류가 발생된 기류는 토출구 측으로 진행하면서 구동모터의 후미에 형성된 꼬깔형 콘에 의해 부딪혀 다시 직선화로 유도되는 바, 결국 직선 기류를 형성하게 된다.In other words, when the impeller is rotated by the rotation of the drive motor, the airflow is caused to vortex while rotating in the rotational direction, that is, the circumferential direction. The vortex generated air flows toward the discharge port side by a cone cone formed at the rear of the drive motor. When hit, it leads to straightening, which eventually forms a straight air stream.

이때, 상기 십자형 고정익은 연장부(220)가 형성되어 팬모터 하우징의 단부으로부터 외측으로 돌출되어 기류의 장거리 직선화를 유도하도록 형성되는 것이 바람직하다.At this time, the cross-shaped fixed blade is preferably formed so that the extension portion 220 is formed to protrude outward from the end of the fan motor housing to induce long distance straightening of the airflow.

또한, 상기 허브가이드는 대공간 기류순환팬 또는 제트팬의 팬모터 하우징의 단부에 결합되도록 하는 것이 바람직하다.
이러한 본 발명에 대하여 부언하면, 연장부(220)의 일측 각 단부는 구동모터(110)의 십자형 고정익(120)과 각각 직접 맞닿으며 결합되도록 형성된다.
즉, 구동모터의 임펠러가 회전하게 되면 팬모터 하우징 내에 기류 흡입에 따른 회전기류(사이클론 기류)가 형성되는데, 이러한 회전기류가 십자형 고정익을 통해 직선화되도록 유도되고, 이후 바로 연결된 연장부에 의해 직선화가 지속되도록 형성된다.
또한, 상기 십자형 고정익(120)과 결합된 연장부(220)의 교차점에는 구동모터(110) 측에서 허브가이드(200) 측으로 진행하는 기류의 방향에 따라 각이 좁아지는 각뿔 또는 원뿔 형태의 콘(210)이 형성된다.
이러한 상기 콘(210)은 구동모터(110) 후미 측 단부와 간격 없이 직접 맞닿으며 결합도록 형성되어 임펠러의 회전에 의해 구동모터 후미에서 발생되는 와류를 방지하면서 직선 기류로 배기시킬 수 있도록 형성된다.
다시 말해, 본원발명은 회전 기류를 직선화함에 있어서, 와류 발생구간이 원천적으로 방지되어 소음 및 진동을 차단함은 물론 기류의 원거리 이송을 현저히 높게 확보할 수 있으며 대류 효율이 크게 개선되는 특징이 있다.
In addition, the hub guide is preferably to be coupled to the end of the fan motor housing of the large space airflow circulation fan or jet fan.
In addition to the present invention, one end of each side of the extension 220 is formed to be in direct contact with each of the cross-shaped fixed blade 120 of the drive motor 110 is coupled.
That is, when the impeller of the drive motor rotates, a rotational airflow (cyclone airflow) is formed in the fan motor housing according to the airflow suction, and this rotational airflow is induced to be straightened through the cross-shaped fixed blade, and then straightening is performed by an extension part directly connected thereto. It is formed to last.
In addition, at the intersection of the extension part 220 coupled to the cross-shaped fixed blade 120, a cone of cone or cone shape of which the angle is narrowed according to the direction of the airflow proceeding from the driving motor 110 side to the hub guide 200 side ( 210 is formed.
The cone 210 is formed to be in direct contact with the rear end portion of the driving motor 110 without any gap, and is formed to be exhausted with a linear airflow while preventing vortices generated at the rear of the driving motor by the rotation of the impeller.
In other words, the present invention in the straightening of the rotary airflow, the vortex generation section is prevented inherently, it is possible to block the noise and vibration as well as to ensure a long distance transport of the airflow is significantly improved and the convection efficiency is greatly improved.
