Description
본 발명은, 스월러 주위에 벽이나 기타 장애물이 존재하더라도 와류를 효율적으로 형성하여 오염된 공기를 보다 효율적으로 흡입 배출할 수 있는 스월러를 이용한 레인지 후드에 관한 것이다.The present invention relates to a range hood using a swirler that can efficiently form a vortex and inhale and discharge contaminated air even if walls or other obstacles exist around the swirler.
기존의 일반적인 배기 장치의 경우 배기구로부터 멀어짐에 따라 배기 속도가 빠르게 감소하여, 효과적인 배기영역이 배기구 직경 정도의 작은 영역에 국한되므로, 배기구로부터 먼 곳에서 발생하는 오염을 제거하기에 적당하지 않았다.Existing general exhaust devices have been rapidly reduced as they move away from the exhaust port, so that the effective exhaust area is limited to a region as small as the diameter of the exhaust port, which is not suitable for eliminating contamination occurring far from the exhaust port.
이러한 단점을 보완하기 위하여 와류를 이용한 배기 장치들이 개발되었으며, 이 장치들은 배기하는 유량과 비슷한 양의 공기를 공간 중으로 불어내어 와류를 발생시키고, 이를 배기 장치가 흡입하는 과정에서 형성되는 집중된 와류를 이용하는 것이다.In order to make up for this drawback, exhaust devices using vortices have been developed, which use a concentrated vortex formed by blowing air into the space, which is comparable to the flow rate of the exhaust. will be.
그러나 상기한 종래의 장치들은 배기구 아래의 좁은 영역에서 불어내는 유동과 흡입하는 유동의 상호 간섭에 의한 난류의 발생으로 소음이 발생하게 되고, 또한 공간 중으로 불어내는 유동에 의하여 공간 중에 있는 오염의 부가적인 확산을 유발할 수 있으며, 와류를 발생하기 위한 송풍기, 필터, 유동관 등의 부가적인 설비를 설치해야 하는 단점을 가지고 있었다.However, the above-described conventional devices generate noise due to the generation of turbulence due to mutual interference of the blowing flow and the intake flow in a narrow area under the exhaust port, and also the addition of contamination in the space by the flow blowing into the space. It may cause diffusion and has the disadvantage of installing additional equipment such as a blower, a filter, and a flow pipe to generate vortices.
그리하여 도 10 및 도 11에 도시한 바와 같이 스월러(4)를 이용한 배기장치가 소개되었으며, 상기 배기장치는, 배기관(1)의 흡입구에 회전가능하게 설치되는 원판 형태의 회전판(2)과, 회전판(2)의 하면에 다수 개가 배열설치되어 와류를 형성하는 날개(3)와, 상기 회전판(2)을 회전시키는 구동부(5)를 포함하였다. 이때, 구동부(5)는 배기관(1)의 내주면에 브라켓(6)을 매개로 고정설치되는 구동모터(7)였다.Thus, as illustrated in FIGS. 10 and 11, an exhaust device using a swirler 4 has been introduced. The exhaust device includes a rotating plate 2 having a disc shape rotatably installed at an inlet of an exhaust pipe 1, A plurality of vanes 3 are arranged on the lower surface of the rotating plate 2 to form a vortex, and a driving unit 5 for rotating the rotating plate 2 is included.

그러나 상기 스월러를 이용한 배기장치는 벽이나 장애물이 존재하는 경우에 균형적인 와류의 생성이 현저하게 저하되어 오염된 공기를 효율적으로 흡입 배출하지 못하는 문제점이 있었다.However, the exhauster using the swirler has a problem in that a balanced vortex generation is significantly reduced in the presence of a wall or an obstacle, so that the polluted air cannot be sucked and discharged efficiently.
또한, 스월러를 회전시키기 위한 구동모터와 흡입팬을 회전시키기 위한 구동모터가 별도로 구비되어야 하므로 구조가 복잡하고 소형화에 문제점이 발생하였다.In addition, since the drive motor for rotating the swirler and the drive motor for rotating the suction fan to be provided separately, the structure is complicated and a problem in miniaturization.
본 발명은 전술한 바와 같은 문제점을 해결하기 위한 것으로, 회전판의 선단으로부터 소정거리 이격되게 가이드벽을 형성하여 스월러 주위에 벽이나 기타 장애물이 존재하더라도 균형적인 와류를 형성할 수 있으므로 오염된 공기를 보다 효율적으로 흡입 배출할 수 있는 스월러를 이용한 레인지 후드를 제공하는데 그 목적이 있다.The present invention is to solve the problems as described above, by forming a guide wall spaced a predetermined distance from the tip of the rotating plate to form a balanced vortex even if there is a wall or other obstacles around the swirler contaminated air It is an object of the present invention to provide a range hood using a swirler capable of suction and discharge more efficiently.
또한, 회전판의 회전중심축을 기울어지게 하여 장애물이 존재하더라도 안정적인 와류를 형성할 수 있고, 회전판의 회전중심축과 흡입팬의 회전중심축을 동일축 상에 형성하여 구조가 간단하며 소형화된 스월러를 이용한 레인지 후드를 제공하는데 다른 목적이 있다.In addition, it is possible to form a stable vortex even if an obstacle exists by tilting the rotation center axis of the rotating plate, and the structure of the rotating center axis of the rotating plate and the suction fan are formed on the same axis so that the structure is simple and using a miniaturized swirler Another purpose is to provide a range hood.
상기와 같은 목적을 달성하기 위하여 본 발명의 바람직한 실시예에 따른 스월러를 이용한 레인지 후드는, 흡입구에 회전가능하게 설치되는 원판 형태의 회전판과, 상기 회전판의 하면에 다수 개가 배열설치되어 와류를 형성하는 날개를 포함하는 스월러를 이용한 레인지 후드에 있어서, 상기 회전판의 선단으로부터 소정거리 이격되어 가이드벽이 형성되고, 상기 가이드벽의 높이는 상기 날개의 높이 보다 큰 것을 특징으로 한다. 상기 가이드벽은 하부로 경사지거나 만곡질 수 있다.Range hood using a swirler in accordance with a preferred embodiment of the present invention, in order to achieve the above object, a disk-like rotating plate is rotatably installed on the suction port, and a plurality of arranged on the lower surface of the rotating plate to form a vortex In the range hood using a swirler comprising a wing, the guide wall is formed spaced apart a predetermined distance from the tip of the rotating plate, the height of the guide wall is characterized in that the height of the wing.

또한, 상기 회전판의 회전중심축과 흡입팬의 회전중심축이 동일축 상에 형성되어 하나의 구동모터로 구동될 수 있다.In addition, the rotation center axis of the rotating plate and the rotation center axis of the suction fan may be formed on the same axis to be driven by one driving motor.

본 발명의 바람직한 실시예를 첨부된 도면을 참조하여 상세히 설명한다. 본 발명을 설명함에 있어, 관련된 공지 구성 또는 기능에 대한 구체적인 설명이 본 발명의 요지를 흐릴 수 있다고 판단되는 경우에는 상세한 설명을 생략한다.Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that the detailed description of the related well-known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.
본 발명의 바람직한 실시예에 따른 흡입구에 회전가능하게 설치되는 원판 형태의 회전판(11)과, 회전판(11)의 하면에 다수 개가 배열설치되어 와류를 형성하는 날개(12)를 포함하는 스월러(10)를 이용한 레인지 후드는, 도 1 또는 도 2에 도시한 바와 같이, 회전판(11)의 선단으로부터 소정거리 이격되어 가이드벽(20)이 형성되고, 가이드벽(20)의 높이는 날개(12)의 높이 보다 큰 것으로서, 스월러(10) 주위에 벽(W)이나 기타 장애물이 존재하더라도 가이드벽(20)이 균형적인 와류를 형성할 수 있으므로 오염된 공기를 보다 효율적으로 흡입 배출할 수 있다.Swirl comprising a rotating plate 11 of a disc shape rotatably installed in the suction port according to a preferred embodiment of the present invention, and wings 12 are arranged on the lower surface of the rotating plate 11 to form a vortex ( As shown in FIG. 1 or 2, the range hood using 10) is spaced apart from the tip of the rotating plate 11 by a predetermined distance to form a guide wall 20, and the height of the guide wall 20 is wing 12. Since the guide wall 20 may form a balanced vortex even when the wall W or other obstacles exist around the swirler 10, the contaminated air may be sucked and discharged more efficiently.
또한, 가이드벽(20)은 원형 또는 다각형 등의 다양한 형태로 회전판(11) 주위에 형성될 수 있고, 가이드벽(20)은 하부로 경사지거나 만곡지게 할 수 있다.In addition, the guide wall 20 may be formed around the rotating plate 11 in various forms such as circular or polygonal, and the guide wall 20 may be inclined or curved downward.
이때, 가이드벽(20)의 높이는 날개(12)의 높이의 5배 이하인 것이 바람직하다. 가이드벽(20)의 높이가 날개(12)의 높이의 5배를 초과하는 경우에는 가이드벽(20) 바깥 쪽으로의 와류 크기의 증가가 없어 배기영역의 증가를 기대할 수 없게 된다.At this time, it is preferable that the height of the guide wall 20 is 5 times or less of the height of the blade | wing 12. If the height of the guide wall 20 exceeds five times the height of the wing 12, there is no increase in the size of the vortex outside the guide wall 20, so that an increase in the exhaust area cannot be expected.
도 3은 가이드벽(20)이 형성되어 있는 경우에 스월러(10)를 이용한 레인지 후드의 유동을 가시화 한 것이고, 도 4는 가이드벽(20)이 형성되어 있지 않는 경우에 스월러(10)를 이용한 레인지 후드의 유동을 가시화 한 것이다.3 illustrates the flow of the range hood using the swirler 10 when the guide wall 20 is formed, and FIG. 4 illustrates the swirler 10 when the guide wall 20 is not formed. The flow of the range hood is visualized.
도 3 및 도 4에서 후면과 우측면에 벽이 형성되어 있고, 유동의 가시화는 하부에 가습기를 설치하여 수증기 입자의 흐름을 10초 간격으로 관찰하였으며, 도 3에서 가이드벽(20)의 좌우측면은 하부로 경사지게 형성되고 가이드벽(20)의 전후면은 수직으로 형성된다.In FIGS. 3 and 4, walls are formed at the rear and right sides, and the visualization of the flow is performed by installing a humidifier at the bottom to observe the flow of water vapor at 10 second intervals. In FIG. 3, the left and right sides of the guide wall 20 are It is formed to be inclined downward and the front and rear surfaces of the guide wall 20 are formed vertically.
도 3에서 확인할 수 있는 바와 같이 스월러(10) 주위에 가이드벽(20)이 형성되면, 수증기 입자가 좌우로 크게 요동치지 않고 레인지 후드를 통해 자연스럽게 흡입 배출된다. 즉, 가이드벽(20)이 날개(12)의 외측으로 유동하는 와류의 시작 흐름을 안정적으로 안내하여 벽(W)이나 기타 장애물이 존재하더라도 회전판(11)의 회전중심축(11a) 양쪽으로 형성되는 와류가 대칭에 가깝게 균형적으로 형성되므로 배기영역의 균형적인 확대가 이루어지면서 원활한 흡입 배출이 가능해지게 된다.As can be seen in FIG. 3, when the guide wall 20 is formed around the swirler 10, the water vapor particles are naturally sucked out through the range hood without greatly swinging from side to side. That is, the guide wall 20 stably guides the starting flow of the vortex flowing out of the wing 12 so as to be formed on both sides of the rotational center axis 11a of the rotating plate 11 even if the wall W or other obstacles exist. Since the vortices are formed in a balanced manner close to the symmetry, a balanced expansion of the exhaust area is achieved and smooth suction discharge is possible.
반면에 가이드벽이 형성되어 있지 않는 경우에는 도 4에서 확인할 수 있는 바와 같이, 수증기 입자가 좌우로 크게 요동치면서 레인지 후드를 통해 흡입 배출되지 못하였고, 이는 시간이 지남에 따라 더욱 심해졌다. 이와 같은 흡입 배출의 심각한 저하는, 스월러(10)의 후면과 우측면에 형성되어 있는 벽이 날개(12)의 외측으로 유동하는 와류의 시작 흐름을 방해하여 회전판(11)의 회전중심축(11a) 양쪽으로 형성되는 와류가 균형적으로 형성되지 못하므로 서로 간섭하게 되면서 원활한 흡입 배출이 불가능해지는 것이다.On the other hand, when the guide wall is not formed, as can be seen in Figure 4, the water vapor particles were not allowed to be sucked out through the range hood while swinging greatly from side to side, which became more severe over time. The serious decrease in suction discharge, such that the walls formed on the rear and right sides of the swirler 10 interfere with the starting flow of the vortices flowing outward of the wing 12, causing the central axis 11a of the rotating plate 11 to be rotated. ) Since the vortices formed on both sides are not balanced, they interfere with each other and smooth suction discharge is impossible.
도 5 내지 도 8에 도시한 바와 같이, 회전판(11)의 회전중심축(11a)이 수직으로부터 1∼10° 기울어져 회전판(11)도 수평으로부터 동일 각도로 기울어져 회전하는 것으로서, 스월러(10) 주위에 벽(W)이나 기타 장애물이 존재하더라도 오염된 공기를 보다 효율적으로 흡입 배출할 수 있다.As shown in Figs. 5 to 8, the center of rotation 11a of the rotating plate 11 is inclined 1 to 10 degrees from the vertical, and the rotating plate 11 is also inclined at the same angle from the horizontal to rotate the swirler ( 10) Even if there is a wall (W) or other obstacles around, the polluted air can be suctioned and discharged more efficiently.
도 5에서와 같이 회전판(11)의 회전중심축(11a)이 수직으로부터 벽(W)쪽으로 기울어진 경우에는 벽(W) 근처의 와류 크기가 조금 증가하긴 하지만 벽(W) 근처의 와류가 훨씬 안정적으로 형성되어 벽(W) 반대편쪽으로 배기영역이 확대되고, 도 6 내지 도 8에서와 같이 회전판(11)의 회전중심축(11a)이 수직으로부터 벽(W) 반대쪽으로 기울어진 경우에는 벽(W) 근처의 와류 크기가 감소하면서 벽(W) 하부쪽으로 배기영역이 확대된다.As shown in FIG. 5, when the rotational center axis 11a of the rotating plate 11 is inclined from the vertical toward the wall W, the vortex near the wall W increases slightly but the vortex near the wall W is much higher. It is formed stably so that the exhaust area is extended to the opposite side of the wall (W), and as shown in Figs. 6 to 8, when the center of rotation axis (11a) of the rotating plate 11 is inclined from the vertical to the opposite side of the wall (W) The exhaust area expands below the wall W while the vortex size near W) decreases.
회전판(11)의 회전중심축(11a)이 수직으로부터 1°미만으로 기울어진 경우에는 벽(W)이나 기타 장애물로 인해 발생하는 비정상적인 와류에 변화를 줄 수 없어 배기영역을 확대하는 것이 불가능하고, 회전판(11)의 회전중심축(11a)이 수직으로부터 11°초과하여 기울어진 경우에는 와류의 비균형이 증폭되어 배기영역이 감소하게 되는 문제점이 있다.When the central axis of rotation 11a of the rotating plate 11 is inclined to less than 1 ° from the vertical, it is impossible to change the abnormal vortex caused by the wall W or other obstacles, and thus it is impossible to enlarge the exhaust area. If the central axis of rotation 11a of the rotating plate 11 is inclined beyond 11 ° from the vertical, there is a problem that the asymmetry of the vortex is amplified and the exhaust area is reduced.
도 9에 도시한 바와 같이, 회전판(11)의 회전중심축(11a)과 흡입팬(30)의 회전중심축(30a)을 동일축 상에 형성하여 하나의 구동모터(40)로 구동할 수 있다. 만약 회전판(11)과 흡입팬(30)의 회전수를 서로 달리 하여야 하는 경우에는 회전판(11)의 회전중심축(11a)과 흡입팬(30)의 회전중심축(30a) 사이에 변속기(미도시)를 설치할 수 있으며, 이 경우에도 여전히 하나의 구동모터(40)로 구동이 가능하다. 이로 인해 스월러(10)와 흡입팬(30)의 구동모터를 각각 구비할 필요가 없으므로 복잡한 구조를 단순화하여 스월러를 이용한 레인지 후드의 소형화와 제조원가의 상당한 절감을 가능하게 한다.As shown in FIG. 9, the central axis of rotation 11a of the rotating plate 11 and the central axis of rotation 30a of the suction fan 30 may be formed on the same axis to be driven by one drive motor 40. have. If the rotational speed of the rotating plate 11 and the suction fan 30 should be different from each other, a transmission (not shown) is provided between the rotating center shaft 11a of the rotating plate 11 and the rotating center shaft 30a of the suction fan 30. C) can be installed, and in this case it is still possible to drive with one drive motor 40. This eliminates the need to provide the drive motors of the swirler 10 and the suction fan 30, respectively, thereby simplifying the complicated structure and miniaturizing the range hood using the swirler and significantly reducing manufacturing costs.
이와 같이 구성된 본 발명의 바람직한 실시예에 따른 스월러를 이용한 레인지 후드의 기능 및 작용을 도 1 내지 도 3을 참조하여 설명하면 다음과 같다.The function and operation of the range hood using a swirler according to the preferred embodiment of the present invention configured as described above will be described with reference to FIGS. 1 to 3.
구동모터(40)에 의해 흡입팬(30)과 회전판(11)이 동시에 회전하게 되고, 회전판(11)의 하면에 형성되는 다수의 날개(12)로 인해 날개(12)의 하부에는 와류가 형성되며, 경사지거나 만곡진 가이드벽(20)은 벽(W) 또는 기타 장애물로 인해 회전중심축(11a) 양쪽으로 형성되는 와류의 비대칭을 상당히 감소시켜 균형적인 와류를 형성하게 되므로 배기영역의 확대가 가능해지고, 오염된 공기는 보다 효율적으로 흡입 배출된다.The suction fan 30 and the rotating plate 11 are rotated at the same time by the driving motor 40, and the vortex is formed at the lower portion of the wing 12 due to the plurality of wings 12 formed on the lower surface of the rotating plate 11. The inclined or curved guide wall 20 greatly reduces the asymmetry of the vortices formed on both sides of the center of rotation 11a due to the wall W or other obstacles, thereby forming a balanced vortex, thereby expanding the exhaust region. It becomes possible, and the polluted air is suctioned out more efficiently.
이때, 회전판(11)의 회전중심축(11a)이 수직으로부터 소정 각도 기울어져 원하는 영역으로의 추가적인 배기영역 확장이 가능하다.At this time, the rotation center axis 11a of the rotating plate 11 is inclined at a predetermined angle from the vertical to further expand the exhaust area to the desired area.
