이때, 천장에 설치된 송풍구의 하단에는 그릴이 설치된다. 그릴은 내부에 공기가 지나가는 통로가 된다. 그러나 상기 그릴은 천정에 항시 고정되어 있으므로, 그릴 내로 지나가는 냉온공기에 포함된 먼지나 오물이 계속해서 그릴에 들러붙게 된다. 이는 위생상으로도 매우 좋지 않을 뿐 아니라, 그릴과 그 주변 및 실내 전체의 미관을 해치게 된다. 따라서 주기적으로 그릴을 청소할 필요가 있는데, 천정에 설치된 그릴을 청소하는 것은 매우 힘들고 번거로운 작업이었다.At this time, the grill is installed at the lower end of the air vent installed on the ceiling. The grill is a passage through which air flows. However, since the grill is always fixed to the ceiling, dust or dirt contained in the hot and cold air passing through the grill continues to stick to the grill. Not only is it very hygienic, it also hurts the grill, its surroundings and the aesthetics of the interior. Therefore, it is necessary to clean the grill periodically, which was very difficult and cumbersome.
이러한 문제를 해결하기 위해 종래에는 천정에 설치된 그릴을 승강시키는 장치가 제안된 바 있다. 도 1을 참조하면, 종래의 그릴 승하강장치는 먼저 구동 모터(1)를 구비한다. 구동 모터(1)는 구동축(2)과 연결되어 함께 회전한다. 구동축(2)은 그릴(6)의 폭(또는, 길이)에 맞먹는 길이를 가진다. 구동축(2)의 양단부에는 각각 2개의 드럼(3, 4)이 쌍을 이루며 설치된다. 각각의 드럼 쌍(3, 4)은 서로 소정 간격으로 이격되어 있다.In order to solve this problem, a device for elevating a grill installed in a ceiling has been proposed. Referring to FIG. 1, a conventional grille elevating device is first provided with a drive motor 1. The drive motor 1 is connected to the drive shaft 2 and rotates together. The drive shaft 2 has a length equal to the width (or length) of the grille 6. Two drums 3 and 4 are provided in pairs at both ends of the drive shaft 2, respectively. Each drum pair 3, 4 is spaced apart from one another at predetermined intervals.
상기 네 개의 드럼(3, 4)에는 각각 와이어(5)가 연결된다. 와이어(5)는 구동 모터(1)가 회전할 때 각각의 드럼(3, 4)에 감기거나 풀리게 된다. Wires 5 are respectively connected to the four drums 3 and 4. The wire 5 is wound or unwound on each drum 3, 4 as the drive motor 1 rotates.
와이어(5)의 타단부는 그릴(6)과 연결된다. 따라서 구동 모터(1)가 회전하여 와이어(5)를 드럼(3, 4)에 감거나 풀 때, 그릴(6)은 와이어를 따라 상승하거나 하강하게 된다.The other end of the wire 5 is connected with the grille 6. Thus, when the drive motor 1 rotates to wind or unwind the wires 5 to the drums 3 and 4, the grille 6 rises or falls along the wires.
또한, 상기 와이어(5)를 안내하기 위한 안내 롤러(7, 8)가 소정 위치에 설치된다. 상기 안내 롤러(7, 8)를 통해 와이어(5)는 드럼(3, 4)과 그릴(6)에 각각 수직하게 연결된다. 상기 안내 롤러(7, 8)는 와이어(5)가 드럼(3, 4)에 원활하게 풀리고 감길 수 있게 하며, 또한 그릴(6)이 와이어(5)에 안정적으로 매달리게 한다. 이를 위해 하나의 안내 롤러(7)는 드럼(3, 4)과 대체로 동일한 높이에 설치되고, 다른 안내 롤러(8)는 그릴(6)에 설치된다. 특히, 안내 롤러(7)는 와이어(5)가 드럼(3, 4)에 원활하게 감기게 하기 위해서 드럼(3, 4)으로부터 충분히 떨어져 있어야 한다.In addition, guide rollers 7 and 8 for guiding the wire 5 are provided at predetermined positions. Through the guide rollers 7, 8 the wire 5 is connected perpendicularly to the drums 3, 4 and the grille 6, respectively. The guide rollers 7, 8 allow the wire 5 to be smoothly unwound and wound on the drums 3 and 4, and also to allow the grill 6 to stably hang on the wire 5. For this purpose one guide roller 7 is installed at substantially the same height as the drums 3, 4, and the other guide roller 8 is installed at the grill 6. In particular, the guide roller 7 must be sufficiently separated from the drums 3 and 4 in order to allow the wires 5 to be smoothly wound on the drums 3 and 4.
한편, 와이어(5)의 타단부는 안내 롤러(8)를 경유하여 연장되며, 스프링(9)을 통해 그릴(6)과 연결된다.On the other hand, the other end of the wire 5 extends via the guide roller 8, and is connected to the grill 6 through the spring 9.
도 2는 종래기술에 따른 다른 형태의 그릴 승하강장치를 도시한다. 도 2에 도시된 그릴 승하강장치는 앞서 설명한 그릴 승하강장치와 실질적으로 동일한 구동 모터(10)를 구비하며, 구동 모터(10)는 구동축(11)과 연결되어 함께 회전한다.Figure 2 shows another type of lifting device according to the prior art. The grill lifting device shown in FIG. 2 includes a driving motor 10 substantially the same as the grill lifting device described above, and the driving motor 10 is connected to the driving shaft 11 to rotate together.
이때, 구동축(11)의 양단부에는 각각 하나씩의 드럼(20, 21)이 소정 간격을 두고 설치된다. 각각의 드럼(20, 21)에는 와이어(30, 31)가 각각 연결된다.At this time, one end of each of the driving shaft 11 is provided with one drum 20, 21 at a predetermined interval. Wires 30 and 31 are connected to the drums 20 and 21, respectively.
상기 와이어(30, 31)는 일단부가 드럼(20, 21)에 연결되고, 타단부는 그릴(40)을 경유하여 소정 높이에 설치된 고정편(41)에 고정된다. 상기 고정편(41)은 대략 드럼(20, 21)과 같거나 더 높은 위치에 설치된다.One end of the wires 30 and 31 is connected to the drums 20 and 21, and the other end thereof is fixed to the fixing piece 41 installed at a predetermined height via the grill 40. The fixing piece 41 is installed at approximately the same position as or higher than the drums 20 and 21.
또한, 와이어(30, 31)는 각각 세 개의 안내 롤러(50, 51, 52)를 경유하여 설치된다. 상기 세 개의 안내 롤러(50, 51, 52) 중에서, 하나의 안내 롤러(50)는 드럼(20, 21)과 동일한 높이에 설치되며, 두 개의 안내 롤러(51, 52)는 그릴(40)에 서로 이격되게 설치된다. 이때에도, 안내 롤러(50)는 와이어(30)가 드럼(20, 21)에 원활하게 감기게 하기 위해서 드럼(20, 21)으로부터 충분한 거리를 가져야 한다.In addition, the wires 30 and 31 are provided via three guide rollers 50, 51 and 52, respectively. Of the three guide rollers 50, 51, 52, one guide roller 50 is installed at the same height as the drums 20, 21, and two guide rollers 51, 52 are mounted on the grill 40. Installed apart from each other. Even at this time, the guide roller 50 should have a sufficient distance from the drum 20, 21 to allow the wire 30 to be smoothly wound on the drum 20, 21.
이와 같은 종래의 그릴 승하강장치는 천정에 설치된 그릴을 하강시켜 청소를 용이하게 한다는 장점이 있다. 그러나 종래의 그릴 승하강장치는 모든 부품을 각각 분리된 위치에 설치한 후, 와이어를 연결하는 작업을 별도로 수행해야 하므로 설치가 매우 번거롭고 많은 시간을 필요로 한다.The conventional grille elevating device has the advantage of easy cleaning by lowering the grille installed on the ceiling. However, the conventional grill hoisting device has to install all the parts in separate positions, and after the wire connection work must be performed separately, the installation is very cumbersome and requires a lot of time.
또한, 종래의 그릴 승하강장치는 와이어가 그릴로부터 쉽게 분리되지 않으므로 청소작업이 매우 불편하며, 특히 교체를 위해 그릴을 분리하고 새로 연결하는 작업이 매우 번거롭다는 단점이 있다.In addition, the conventional grill lifting device is very inconvenient because the wire is not easily separated from the grill, there is a disadvantage in that it is very cumbersome to separate and connect the grill for replacement in particular.

도 3은 본 발명의 일실시예에 따른 공기조화기용 그릴 승하강장치를 도시하는 사시도이다.Figure 3 is a perspective view showing a grill lift device for an air conditioner according to an embodiment of the present invention.
도 3을 참조하면, 본 실시예의 그릴 승하강장치는 대략적으로 본체(610), 승강릴(A) 및 와이어(700, 700a)를 포함한다.Referring to Figure 3, the grill lifting device of the present embodiment includes a main body 610, the lifting reel (A) and the wires 700, 700a.
본체(610)는 공기조화기의 냉온공기가 방출되는 천장에 고정된다. 바람직하게, 본체(610)는 중간이 비어 있는 중공형 형태이고, 본체(610)의 중공을 통해서 공기조화기의 냉온공기가 실내로 방출된다.The main body 610 is fixed to the ceiling where the cold and hot air of the air conditioner is discharged. Preferably, the main body 610 has a hollow shape in which the middle is empty, and the cold and hot air of the air conditioner is discharged into the room through the hollow of the main body 610.
승강릴(A)은 쌍으로 이루어지며, 상기 한 쌍의 승강릴(A)은 본체(610)에 서로 이격되게 설치된다. 바람직하게, 한 쌍의 승강릴(A)은 본체(610)의 양측 내벽에 서로 마주보도록 설치된다.Lifting reel (A) is made of a pair, the pair of lifting reel (A) is installed on the body 610 to be spaced apart from each other. Preferably, the pair of lifting reel (A) is installed to face each other on both inner walls of the main body 610.
상기 승강릴(A)에는 와이어(700, 700a)가 각각 연장된다. 상기 와이어(700, 700a)의 타단부는 상기 본체(610)의 중공을 덮을 수 있는 그릴(600)에 연결된다. 상기 와이어(700, 700a)는 승강릴(A) 내에 구비된 드럼(200, 200a)(도 4 참조)에 감기거나 풀리면서 그릴(600)을 상하로 이동시키게 된다. Wires 700 and 700a extend in the lifting reels A, respectively. The other ends of the wires 700 and 700a are connected to a grill 600 that can cover the hollow of the body 610. The wires 700 and 700a move the grill 600 up and down while winding or unwinding the drums 200 and 200a (see FIG. 4) provided in the lifting reel A. Referring to FIG.
도 4는 상기 승강릴(A)의 내부구조를 도시하는 사시도이다. 승강릴(A)은 자신이 외형을 이루며 후술하는 각종 부품을 내장하는 외부 케이싱(800)(도 8 참조)을 구비한다. 도 4에서는 편의상 외부 케이싱은 도시되지 않았다.4 is a perspective view illustrating an internal structure of the lifting reel A. FIG. The lifting reel A has an outer casing 800 (see FIG. 8) which forms various shapes thereof and houses various components described later. In Figure 4 the outer casing is not shown for convenience.
상기 외부 케이싱(800) 내에는 후술하는 구동 모터(110), 구동축(100), 제1 및 제2 드럼(200, 200a), 안내롤러부(620) 등이 설치된다.In the outer casing 800, a driving motor 110, a driving shaft 100, first and second drums 200 and 200a, a guide roller 620, and the like, which are described later, are installed.
구동 모터(110)는 외부의 전원을 이용하여 회전력을 제공하는 역할을 한다.The drive motor 110 serves to provide rotational force by using an external power source.
구동축(100)은 구동 모터(110)에 연결되고, 구동 모터(110)의 회전력을 전달받아 회전한다.The drive shaft 100 is connected to the drive motor 110 and rotates by receiving the rotational force of the drive motor 110.
제1 및 제2 드럼(200, 200a)은 상기 구동축(100)에 결합되어 상기 구동축(100)과 함께 회전한다. 바람직하게, 상기 구동축(100)은 종래에 비해 짧은 길이를 가지며, 상기 제1 및 제2 드럼(200, 200a)은 상기 구동 모터(110)와 매우 가깝게 배치된다. 이러한 구조는 부품이 차지하는 부피를 줄여 상기 외부 케이싱(800)(도 8 참조)의 크기를 줄이는데 도움이 된다. 또한, 상기 제1 및 제2 드럼(200, 200a)에는 각각 와이어(700, 700a)가 연결된다. 각각의 와이어(700, 700a)는 상기 제1 및 제2 드럼(200, 200a)에 서로 동일한 방향으로 감기거나 풀리며, 상기 제1 및 제2 드럼(200, 200a)으로부터 서로 반대 방향으로 연장된다.The first and second drums 200 and 200a are coupled to the drive shaft 100 to rotate together with the drive shaft 100. Preferably, the drive shaft 100 has a shorter length than the conventional one, and the first and second drums 200 and 200a are disposed very close to the drive motor 110. This structure helps to reduce the size of the outer casing 800 (see FIG. 8) by reducing the volume occupied by the component. In addition, wires 700 and 700a are connected to the first and second drums 200 and 200a, respectively. Each of the wires 700 and 700a is wound or unwound in the same direction to each other on the first and second drums 200 and 200a, and extends in opposite directions from the first and second drums 200 and 200a.
이때, 상기 제1 및 제2 드럼(200, 200a)은 서로 상대적 회전이 가능하도록 밀착되게 배치되는 것이 바람직하다. 이를 위해서, 상기 제1 및 제2 드럼(200, 200a)은 양 측면에 각각 연결돌기(210, 210a) 및 연결홈(220, 220a)이 형성되는 것이 바람직한데, 이는 상기 제1 및 제2 드럼(200, 200a)의 단면을 도시하는 도 5에 잘 나타나 있다.In this case, the first and second drums 200 and 200a may be disposed in close contact with each other to allow relative rotation. To this end, it is preferable that the first and second drums 200 and 200a have connecting protrusions 210 and 210a and connecting grooves 220 and 220a respectively formed at both sides thereof, which are the first and second drums. It is shown well in FIG. 5 which shows the cross section of (200, 200a).
도 5를 참조하면, 상기 제1 및 제2 드럼(200, 200a)의 서로 마주보는 측면에는 각각 연결홈(220) 및 연결돌기(210a)가 형성되어 있어, 제1 및 제2 드럼(200, 200a)이 서로 맞닿을 때, 제2 드럼(200a)의 연결돌기(210a)가 제1 드럼(200)의 연결홈(220)에 끼워지면서 제1 및 제2 드럼(200, 200a)이 서로 상대적 회전이 가능하게 맞물리게 된다. 이때, 제1 및 제2 드럼(200, 200a)은 각각 연결홈과 연결돌기 중 어느 하나만을 구비할 수도 있으나, 대량생산 가능성 등을 고려하여 연결홈과 연결돌기를 모두 구비하는 것이 바람직하다. 드럼(200)의 연결돌기(210)는 드럼(200)의 측단면을 도시하는 도 7에도 잘 나타나 있다.Referring to FIG. 5, connecting grooves 220 and connecting protrusions 210a are formed on side surfaces of the first and second drums 200 and 200a facing each other, respectively, so that the first and second drums 200, When the 200a are in contact with each other, the connecting protrusion 210a of the second drum 200a is fitted into the connecting groove 220 of the first drum 200, and the first and second drums 200 and 200a are relative to each other. Rotation is possible to engage. In this case, each of the first and second drums 200 and 200a may include only one of the connection grooves and the connection protrusions, but it is preferable to include both the connection grooves and the connection protrusions in consideration of the possibility of mass production. The connecting protrusion 210 of the drum 200 is also shown well in FIG. 7, which shows a side cross section of the drum 200.
한편, 그릴(600)을 상승시키기 위해 와이어(700, 700a)를 제1 및 제2 드럼(200, 200a)에 감을 때 와이어(700, 700a)의 감김 편차를 줄이기 위해서, 상기 제1 및 제2 드럼(200, 200a)과 함께 제1 및 제2 부싱(300, 300a), 브라켓(400), 제1 및 제2 스프링(500, 500a) 등이 설치될 수 있다.Meanwhile, in order to reduce the winding deviation of the wires 700 and 700a when the wires 700 and 700a are wound on the first and second drums 200 and 200a to raise the grill 600, the first and second parts are wound. The first and second bushings 300 and 300a, the bracket 400, and the first and second springs 500 and 500a may be installed together with the drums 200 and 200a.
도 6를 참조하면, 제1 및 제2 부싱(300, 300a)은 각각 제1 및 제2 드럼(200, 200a)의 일측면, 바람직하게는 상기 구동 모터(110)를 향하는 측면에 설치되어 제1 및 제2 드럼(200, 200a)이 구동축(100)과 함께 회전하도록 지지한다. 특히, 제1 및 제2 드럼(200, 200a)이 서로 결합되어 구동축(100)에 삽입되면, 제1 부싱(300)은 제1 드럼(200)의 연결돌기(210)와 결합되어 제1 드럼(200)을 구동축(100)에 대해 회전 가능하게 지지한다.Referring to FIG. 6, the first and second bushings 300 and 300a may be installed at one side of the first and second drums 200 and 200a, respectively, preferably on the side facing the driving motor 110. The first and second drums 200 and 200a are supported to rotate together with the drive shaft 100. In particular, when the first and second drums 200 and 200a are coupled to each other and inserted into the driving shaft 100, the first bushing 300 is coupled to the connection protrusion 210 of the first drum 200 to be connected to the first drum. It supports (200) rotatably with respect to the drive shaft (100).
또한, 브라켓(400)은 구동축(100)과 제2 드럼(200a)을 지지하도록 구성된다. 보다 상세히 설명하면, 제1 드럼(200)의 연결홈(220)과 제2 드럼(200a)의 연결돌기(210a)가 서로 맞물려 제1 및 제2 드럼(200, 200a)이 서로 상대적 회전이 가능하도록 결합되면, 구동축(100)이 제1 및 제2 드럼(200, 200a)의 중심홀을 통해 끼워져, 제1 및 제2 드럼(200, 200a)은 구동축(100)에 회전 가능하게 결합된다.In addition, the bracket 400 is configured to support the drive shaft 100 and the second drum 200a. In more detail, the connecting groove 220 of the first drum 200 and the connecting protrusion 210a of the second drum 200a are engaged with each other so that the first and second drums 200 and 200a may be relatively rotated with each other. When coupled to each other, the drive shaft 100 is fitted through the center holes of the first and second drums 200 and 200a, and the first and second drums 200 and 200a are rotatably coupled to the drive shaft 100.
구동축(100)의 일단부는 구동 모터(110)에 연결된 상태이며, 구동축(100)의 타단부는 브라켓(400)에 회전 가능하게 결합된다. 이 상태에서, 구동축(100)은 흔들림 없이 회전이 가능하다. 또한, 브라켓(400)은 상기 제2 드럼(200a)의 연결홈(220a)에 상응하는 위치에 연결축(410)을 구비하여, 제2 드럼(200a)을 회전 가능하게 지지한다. 즉, 브라켓(400)은 구동축(100)과 제2 드럼(200a)을 모두 지지하여 안정된 구조를 만들게 된다.One end of the drive shaft 100 is connected to the drive motor 110, and the other end of the drive shaft 100 is rotatably coupled to the bracket 400. In this state, the drive shaft 100 can be rotated without shaking. In addition, the bracket 400 includes a connecting shaft 410 at a position corresponding to the connecting groove 220a of the second drum 200a to rotatably support the second drum 200a. That is, the bracket 400 supports both the drive shaft 100 and the second drum 200a to make a stable structure.
제1 및 제2 스프링(500, 500a)은 제1 및 제2 드럼(200, 200a)의 중심홀에, 즉 제1 및 제2 드럼(200, 200a)과 구동축(100) 사이에 설치된다. 상기 스프링(500, 500a)을 설치하기 위해서, 구동축(100)의 외주면에는 단턱(120)(도 7 참조)이 형성되고, 제1 및 제2 드럼(200, 200a)에는 소정 위치에 삽입홈(230, 230a)이 형성된다. 또한, 제1 및 제2 스프링(500, 500a)은 일단부에 걸림고리(520, 520a)가 형성되고 타단부에 삽입핀(510, 510a)이 형성된다. 이때, 제1 및 제2 스프링(500, 500a)의 걸림고리(520, 520a)는 구동축(100)의 단턱(120)에 삽입되어 고정되고, 제1 및 제2 스프링(500, 500a)의 삽입핀(510, 510a)은 제1 및 제2 드럼(200, 200a)의 삽입홈(230, 230a)에 삽입되어 고정된다. 이러한 구성을 통해, 제1 및 제2 스프링(500, 500a)은 제1 및 제2 드럼(200, 200a)을 구동축(100)에 탄성적으로 고정시킨다.The first and second springs 500 and 500a are installed in the center holes of the first and second drums 200 and 200a, that is, between the first and second drums 200 and 200a and the driving shaft 100. In order to install the springs 500 and 500a, a stepped portion 120 (see FIG. 7) is formed on an outer circumferential surface of the drive shaft 100, and insertion grooves are formed at predetermined positions in the first and second drums 200 and 200a. 230, 230a) are formed. In addition, the first and second springs 500 and 500a have hooks 520 and 520a at one end and insertion pins 510 and 510a at the other end. In this case, the engaging rings 520 and 520a of the first and second springs 500 and 500a are inserted into and fixed to the stepped portion 120 of the drive shaft 100 and the first and second springs 500 and 500a are inserted. The pins 510 and 510a are inserted into and fixed to the insertion grooves 230 and 230a of the first and second drums 200 and 200a. Through this configuration, the first and second springs 500 and 500a elastically fix the first and second drums 200 and 200a to the drive shaft 100.
이와 같은 제1 및 제2 드럼(200, 200a)과 구동축(100) 사이의 탄성결합은 각 드럼(200, 200a)에 감기는 와이어(700, 700a)의 감김 편차가 발생할 때 매우 유용하다. 다시 말하면, 와이어(700, 700a) 사이에 감김 편차가 발생한 상태에서 와이어(700, 700a)가 감길 경우, 그릴(600)이 기울어져 상기 본체(610)에 그릴(600)의 일측면이 먼저 닿을 수 있다. 이때, 해당측의 드럼은 더 이상 와이어를 감을 수 없으므로, 그릴(600)인 일측면만 본체(610)에 닿고 타측면은 떨어진 상태가 된다. 이때, 드럼(200, 200a)은 상술한 것처럼 스프링(500, 500a)에 의해 탄성적으로 결합되어 있으므로, 드럼이 회전하지 않더라도 구동축(100)은 스프링(500, 500a)의 탄성력을 이겨내면서 어느 정도 더 회전이 가능하다. 따라서 일측의 드럼이 멈춘 상태에서 타측의 드럼이 더 회전하게 되어 그릴(600)은 전체면이 모두 본체(610)에 밀착될 수 있다.Such elastic coupling between the first and second drums 200 and 200a and the drive shaft 100 is very useful when a winding deviation of the wires 700 and 700a wound around the drums 200 and 200a occurs. In other words, when the wires 700 and 700a are wound in a state in which a winding deviation occurs between the wires 700 and 700a, the grill 600 is inclined so that one side of the grill 600 contacts the main body 610 first. Can be. At this time, since the drum of the corresponding side can no longer wind the wire, only one side of the grill 600 touches the main body 610 and the other side is in a state of being separated. At this time, since the drums 200 and 200a are elastically coupled by the springs 500 and 500a as described above, the driving shaft 100 overcomes the elastic force of the springs 500 and 500a even if the drum does not rotate. More rotation is possible. Therefore, the drum of the other side is further rotated in a state where the drum of one side is stopped, the entire surface of the grill 600 may be in close contact with the main body 610.
다시 도 4를 참조하면, 안내롤러부(620)는 상기 제1 및 제2 드럼(200, 200a)에 연결된 와이어(700, 700a)가 경유하며 연장방향을 바꾸게 한다. 이러한 안내롤러부(620)는 상기 제1 및 제2 드럼(200, 200a)의 양측 위치에 각각 설치되는 내부 케이싱(820), 및 상기 내부 케이싱(820) 내에 설치된 하나 이상의 롤러(622)를 포함한다. 상기 롤러(622)는 와이어(700, 700a)가 상기 제1 및 제2 드럼(200, 200a)에 수직이 되고, 또한 와이어(700, 700a)가 그릴(600)에 수직이 되게 한다.Referring back to FIG. 4, the guide roller part 620 allows the wires 700 and 700a connected to the first and second drums 200 and 200a to change their extension directions. The guide roller part 620 includes an inner casing 820 installed at both sides of the first and second drums 200 and 200a, and at least one roller 622 installed in the inner casing 820. do. The roller 622 allows wires 700 and 700a to be perpendicular to the first and second drums 200 and 200a and also to wires 700 and 700a to the grill 600.
한편, 상기 안내롤러부(620)는 바람직하게 세 개 이상의 롤러(622)를 구비한다. 이 경우, 제1 및 제2 드럼(200, 200a) 각각에 연결된 와이어(700, 700a)는 각 롤러(622)를 경유하게 된다. 이때, 그릴(600)과 가장 가까운 롤러는 그릴(600)의 최적 위치에 맞게 고정되고, 그 외의 롤러는 구동축(100) 방향을 따라 이동하게 구성될 수 있다. 이 경우, 와이어(700, 700a)가 드럼(200, 200a)으로부터 풀리거나 감길 때, 드럼(200, 200a) 상에서 감기거나 풀리는 와이어(700, 700a)의 위치에 따라 롤러가 이동되며, 와이어(700, 700a)를 지속적으로 드럼(200, 200a)에 수직인 상태를 유지한다. 이러한 구성에 의해서, 다수의 롤러(622)가 상대적으로 작은 크기의 내부 케이싱(810) 내에 모두 수용되더라도, 와이어(700, 700a)가 드럼(200, 200a)으로부터 먼 거리로 이격된 롤러를 경유하는 것과 동일한 효과를 제공하게 된다. 이러한 구조는 승강릴(A)의 단면을 도시하는 도 8에 잘 나타나 있다.On the other hand, the guide roller portion 620 is preferably provided with three or more rollers 622. In this case, the wires 700 and 700a connected to the first and second drums 200 and 200a respectively pass through the rollers 622. In this case, the roller closest to the grill 600 may be fixed to an optimal position of the grill 600, and the other rollers may be configured to move along the direction of the drive shaft 100. In this case, when the wires 700 and 700a are released or wound from the drums 200 and 200a, the roller is moved according to the position of the wires 700 and 700a which are wound or unwound on the drums 200 and 200a, and the wire 700 , 700a is continuously maintained perpendicular to the drums 200 and 200a. With this configuration, even if a plurality of rollers 622 are all accommodated in a relatively small inner casing 810, the wires 700 and 700a pass through the rollers spaced far from the drums 200 and 200a. Will provide the same effect as This structure is shown well in FIG. 8, which shows a cross section of the lifting reel A. FIG.
상기 내부 케이싱(820)은 바람직하게 상기 제1 및 제2 드럼(200, 200a)과 동일한 높이에 상기 제1 및 제2 드럼(200, 200a)과 다소 이격된 위치에 배치된다.The inner casing 820 is preferably disposed at a position slightly spaced apart from the first and second drums 200, 200a at the same height as the first and second drums 200, 200a.
이와 같은 승강릴(A)의 부품, 즉 구동 모터(110), 구동축(100), 제1 및 제2 드럼(200, 200a), 안내롤러부(620) 등은 모두 승강릴(A)의 외부 케이싱(800) 내에 수용되며, 하나의 모듈을 구성한다. 이러한 승강릴 모듈(A)은 미리 제작되어 모듈 형태로 운반 및 판매될 수 있다. 따라서 본 발명에 따르는 그릴 승하강장치를 설치하기 위해서는, 복잡한 부품을 현장에서 일일이 설치할 필요 없이 승강릴 모듈(A)을 본체(610)의 적절한 위치에 부착하기만 하면 되므로 설치가 매우 간편하고 효율적이다. 특히, 와이어(700, 700a) 역시 승강릴(A) 내의 드럼(200, 200a)에 미리 연결되어 모듈의 일부로 구성될 경우 설치작업의 효율성이 보다 증대될 수 있다.The components of the lifting reel A, that is, the driving motor 110, the driving shaft 100, the first and second drums 200 and 200a, the guide roller part 620, and the like, are all external to the lifting reel A. It is housed in the casing 800 and constitutes one module. The lifting reel module A may be manufactured in advance and transported and sold in the form of a module. Therefore, in order to install the grill lifting device according to the present invention, the installation is very simple and efficient because it is only necessary to attach the lifting reel module A to the proper position of the main body 610 without having to install complicated parts in the field. . In particular, when the wires 700 and 700a are also pre-connected to the drums 200 and 200a in the lifting reel A to be configured as part of the module, the efficiency of installation work may be further increased.
한편, 제1 및 제2 드럼(200, 200a)으로부터 연장된 와이어(700, 700a)의 끝단에는 후크(820)가 설치된다. 후크(820)는 그릴(600)에 용이하게 걸리고 걸림이 해제되는 형상이라면 어떠한 구조로도 형성될 수 있다. 이러한 후크(820)를 이용하여, 와이어(700, 700a)는 그릴(600)에 착탈이 용이하게 결합될 수 있다.Meanwhile, hooks 820 are installed at ends of the wires 700 and 700a extending from the first and second drums 200 and 200a. The hook 820 may be formed in any structure as long as the hook 600 is easily caught and the latch is released. By using the hook 820, the wires 700 and 700a may be easily attached to or detached from the grill 600.
본 발명에서 와이어(700, 700a)는 각 승강릴(A)에 구비된 두 개의 드럼(200, 200a)에 각각 하나씩 연결된다. 또한, 상술한 승강릴(A)은 두 개가 본체(610)에 서로 이격되게 설치되어, 본 발명에서는 총 4개의 와이어(700, 700a)가 사용된다. 4 개의 와이어(700, 700a)는 그릴(600)이 기울어지거나 회전하지 않게 잡아주는 최적의 개수이며, 물론 이 외에 와이어의 개수를 변경하는 것도 물론 가능하다.In the present invention, the wires 700 and 700a are connected to one of the two drums 200 and 200a provided in each lifting reel A, respectively. In addition, two lifting reel (A) described above are installed on the main body 610 to be spaced apart from each other, a total of four wires (700, 700a) is used in the present invention. The four wires 700 and 700a are optimal numbers to hold the grill 600 not to tilt or rotate, and of course, it is also possible to change the number of wires.
이와 같이 구성된 본 발명에 따른 그릴 승하강장치는 다음과 같이 동작한다.The grill lifting device according to the present invention configured as described above operates as follows.
먼저, 본 발명의 그릴 승하강장치가 건물의 천장에 설치된 상태이고, 그릴(600)은 본체(610)에 밀착되게 고정된 상태라고 가정한다. 이 상태에서 승강릴(A)에 전원을 인가하면, 구동 모터(110)가 회전력을 전달한다. 이 회전력에 의해 구동축(100)이 회전하면서 제1 및 제2 드럼(200, 200a)을 회전시킨다. 제1 및 제2 드럼(200, 200a)이 회전하면, 제1 및 제2 드럼(200, 200a)에 각각 권취된 와이어(700, 700a)가 안내롤러부(620)의 롤러(622)를 따라 풀리게 되고, 와이어(700, 700a)의 단부에 설치된 후크(820)와 결합된 그릴(600)이 하강하게 된다. 이때, 제1 부싱(300)과 제1 스프링(500)은 제1 드럼(200)과 동시에 회전하고, 제2 부싱(300a)과 제2 스프링(500a)은 제2 드럼(200a)과 동시에 회전한다.First, assume that the grill lifting device of the present invention is installed on the ceiling of the building, and the grill 600 is fixed to the main body 610. When power is applied to the lifting reel (A) in this state, the drive motor 110 transmits the rotational force. The driving shaft 100 rotates the first and second drums 200 and 200a by this rotational force. When the first and second drums 200 and 200a rotate, the wires 700 and 700a wound around the first and second drums 200 and 200a respectively follow the rollers 622 of the guide roller part 620. As it is loosened, the grill 600 coupled with the hook 820 installed at the ends of the wires 700 and 700a is lowered. In this case, the first bushing 300 and the first spring 500 rotate simultaneously with the first drum 200, and the second bushing 300a and the second spring 500a rotate simultaneously with the second drum 200a. do.
그릴(600)이 원하는 위치가지 하강하면 구동 모터(110)를 정지시켜 그릴(600)의 하강을 멈추게 하고, 이 상태에서 그릴(600)을 세척하거나 교환하는 등 필요한 작업을 수행한다. 이후 다시 그릴(600)을 원위치로 돌리기 위해서는 구동 모터(110)를 반대 방향으로 역회전시킨다. 그러면, 와이어(700, 700a)는 안내롤러부(620)의 롤러(622)를 경유하여 제1 및 제2 드럼(200, 200a)에 감기게 되고, 그릴(600)은 와이어(700, 700a)를 따라 상승하게 된다.When the grill 600 descends to the desired position, the driving motor 110 is stopped to stop the lowering of the grill 600, and in this state, the grill 600 is washed or replaced to perform necessary operations. Thereafter, in order to return the grill 600 to its original position, the driving motor 110 is rotated in the opposite direction. Then, the wires 700 and 700a are wound on the first and second drums 200 and 200a via the rollers 622 of the guide roller part 620, and the grill 600 is connected to the wires 700 and 700a. Will rise along.
한편, 그릴(600)이 상승할 때, 와이어(700, 700a)는 제1 및 제2 드럼(200, 200a)의 외주면에서 좌우로 이동하며 제1 및 제2 드럼(200, 200a) 외주면 전체에 균일하게 감겨야 한다. 그렇지 않을 경우, 그릴(600)은 수평을 유지하지 못하게 되며, 따라서 그릴(600)이 완전히 상승하더라도 본체(610)에 완전히 밀착하지 못한다. 다시 말하면, 와이어(700, 700a)가 제1 및 제2 드럼(200, 200a)에 감길 때, 어느 한쪽의 와이어가 해당 드럼의 외주면 일부에만 감기게 되면 양쪽 와이어 사이에 감김 편차가 발생한다. 이는 그릴(600)이 수평을 유지하지 못하고 한쪽으로 기울어지게 하며, 결국 그릴(600)이 본체(610)에 기울어진 상태로 밀착되게 한다.On the other hand, when the grill 600 is raised, the wires 700 and 700a move left and right on the outer circumferential surfaces of the first and second drums 200 and 200a, and the entire outer circumferential surfaces of the first and second drums 200 and 200a. It should be wound evenly. Otherwise, the grill 600 may not be horizontal, and thus, the grill 600 may not be completely in contact with the main body 610 even when the grill 600 is fully raised. In other words, when the wires 700 and 700a are wound on the first and second drums 200 and 200a, if one of the wires is wound only on a part of the outer circumferential surface of the drum, a winding deviation occurs between both wires. This causes the grill 600 to be inclined to one side rather than being horizontal, and eventually causes the grill 600 to be in close contact with the main body 610.
이 경우, 한쪽으로 편중되어 감긴 와이어와 정상적으로 감긴 와이어 사이의 감김 편차를 없애야 그릴(600)이 기울어지지 않고 정상적으로 본체(610)와 결합된다. 이 과정을 예를 들어 설명하면 다음과 같다.In this case, it is necessary to eliminate the winding deviation between the wire wound by being biased to one side and the normally wound wire, so that the grill 600 is normally inclined with the main body 610 without being inclined. An example of this process is as follows.
예를 들어, 와이어(700, 700a)가 제1 및 제2 드럼(200, 200a)에 감길 때, 제1 드럼(200)에 감기는 와이어(700)가 한쪽 방향으로 편중되고, 제2 드럼(200a)에 감기는 와이어(700a)는 정상적으로 감긴다고 가정한다. 이때, 제1 드럼(200)에 감기는 와이어는 한쪽으로 편중되어 감기기 때문에, 제2 드럼(200a)에 좌우로 이동하면서 균일하게 감기는 와이어(700a)보다 약간 많은 양의 와이어(700)가 제1 드럼(200)에 감기게 된다. 따라서 그릴(600)은 정상적으로 감기는 와이어(700a)에 결합된 측면보다 편중되어 감기는 와이어(700)에 결합된 측면이 본체(610)에 먼저 밀착되게 된다.For example, when the wires 700 and 700a are wound around the first and second drums 200 and 200a, the wires 700 wound around the first drum 200 are biased in one direction and the second drum ( It is assumed that the wire 700a wound around 200a is normally wound. At this time, since the wire wound on the first drum 200 is biased and wound on one side, a slightly larger amount of wire 700 is formed than the wire 700a that is uniformly wound while moving left and right on the second drum 200a. 1 is wound on the drum (200). Therefore, the grill 600 is biased than the side coupled to the wire 700a which is normally wound, and the side coupled to the winding wire 700 is in close contact with the main body 610 first.
이때, 와이어(700)는 제1 드럼(200)에 완전히 밀착된 상태이므로, 제1 드럼(200)은 더 이상 회전하지 않고 정지된 상태인 반면, 와이어(700a)는 제2 드럼(200a)에 조금 더 감겨야 한다. 따라서 제2 드럼(200a)은 여전히 회전하는 상태이다. 또한, 그릴(600)의 한 측면(와이어(700)가 결합된 측면)은 본체(610)에 이미 밀착된 상태이고, 다른 측면(와이어(700a)가 결합된 측면)은 본체(610)에 아직 접하지 못한 상태이다.In this case, since the wire 700 is completely in close contact with the first drum 200, the first drum 200 is stopped and no longer rotates, while the wire 700a is connected to the second drum 200a. You need to wind up a little more. Therefore, the second drum 200a is still rotating. In addition, one side of the grill 600 (the side to which the wire 700 is coupled) is already in close contact with the main body 610, and the other side (the side to which the wire 700a is coupled) is still attached to the main body 610. There is no contact.
이 상태에서 제1 드럼(200)은 정지한 상태지만, 제1 드럼(200)과 구동축(100) 사이에 제1 스프링(500)이 개재되어 제1 드럼과 구동축(100)을 탄성적으로 결합하고 있는 상태이므로, 제1 스프링(500)이 구동축(100)의 회전방향으로 수축하면서 구동축(100)이 조금 더 회전할 수 있게 된다. 따라서, 제2 드럼(200a)은 구동축(100)을 따라 더 회전하면서 와이어(700a)가 제2 드럼(200a)에 감기게 된다. 결과적으로, 와이어(700a)가 결합된 그릴(600)의 측면 또한 본체(610)에 완전히 밀착되게 된다.In this state, although the first drum 200 is stopped, the first spring 500 is interposed between the first drum 200 and the driving shaft 100 to elastically couple the first drum and the driving shaft 100. Since the first spring 500 is contracted in the rotational direction of the drive shaft 100, the drive shaft 100 can rotate slightly. Therefore, the wire 700a is wound around the second drum 200a while the second drum 200a is further rotated along the drive shaft 100. As a result, the side surface of the grill 600 to which the wire 700a is coupled is also brought into close contact with the main body 610.
도 9 및 도 10은 본 발명의 다른 실시예를 도시한다. 본 실시예는 앞선 실시예와 실질적으로 동일하나 다만 제1 및 제2 드럼(200, 200a)과 구동축(100)을 탄성적으로 연결하는 수단으로 태엽스프링(750, 750a)을 이용한다.9 and 10 show another embodiment of the present invention.

In other words, insertion grooves 230 and 230a are formed in the inner circumferential surfaces of the first and second drums 200 and 200a, and long grooves 120a are formed in the outer circumferential surface of the drive shaft 100. In addition, insertion pins 710 and 710a are formed at one end of the first and second springs 750 and 750a, and hooks 720 and 720a are formed at the other ends of the first and second springs 750 and 750a. Are each formed.
제1 및 제2 태엽스프링(750, 750a)의 삽입핀(710, 710a)은 제1 및 제2 드럼(200, 200a)의 삽입홈(230, 230a)에 각각 삽입되어 고정되고, 제1 및 제2 태엽스프링(750, 750a)의 걸림고리(720, 720a)는 구동축(100)의 장홈에 각각 삽입되어 고정된다. 이와 같은 구성에 의해 제1 및 제2 태엽스프링(750, 750a)은 제1 및 제2 드럼(200, 200a)을 구동축(100)에 탄성적으로 결합시키게 된다.The insertion pins 710 and 710a of the first and second springs 750 and 750a are inserted into and fixed to the insertion grooves 230 and 230a of the first and second drums 200 and 200a, respectively. Engaging rings 720 and 720a of the second springs 750 and 750a are inserted into and fixed to the long grooves of the drive shaft 100, respectively. By such a configuration, the first and second springs 750 and 750a elastically couple the first and second drums 200 and 200a to the drive shaft 100.
이와 같이 구성된 본 발명에 따른 그릴 승하강장치는 그릴을 승하강시키는 승강릴의 주요 부품을 외부 케이싱 내에 모듈 형태로 구성하기 때문에, 설치가 매우 간편하고 효율적이라는 장점이 있다.The grille elevating device according to the present invention configured as described above has the advantage that the installation is very easy and efficient because the main components of the elevating reel to raise and lower the grille in a modular form in the outer casing.
또한, 본 발명의 그릴 승하강장치는 와이어 하단에 후크를 설치하여 와이어를 그릴에 간편하게 부착 및 분리하는 것이 가능하다.In addition, the grill lifting device of the present invention can easily attach and detach the wire to the grill by installing a hook at the bottom of the wire.
또한, 승강릴의 드럼과 구동 모터의 구동축 사이에 스프링, 특히 태엽스프링을 설치하여 드럼과 구동축이 서로 탄력적으로 결합하게 함으로써, 그릴이 기울어지더라도 본체에는 그릴의 전면이 완전히 밀착하게 한다는 장점이 있다.In addition, by installing a spring, in particular a spring spring between the drum of the lifting reel and the drive shaft of the drive motor to elastically couple the drum and the drive shaft, there is an advantage that the front of the grill is in close contact with the body even if the grill is tilted. .
