본 고안은 모터로 날개차 또는 로터 등의 회전부재를 회전시킴으로써 외부의 공기를 소정의 압력을 갖는 공기로 전환시켜 토출구를 통해서 공기를 토출시키는 송풍기에 관한것으로, 특히 상부 및 하부의 양방향으로 토출구를 갖는 송풍기에 있어서 송풍 케이스의 내부에 배설되는 회전부재의 위치를 소정의 압력을 갖는 공기가 토출되는 조건에 따라서 가변시킬수 있도록 하여서 송풍기의 송풍 효율을 향상시킬수 있는 양방향 토출 송풍기의 회전부재 이동장치에 관한 것이다.The present invention relates to a blower for discharging the air through the discharge port by converting the outside air into air having a predetermined pressure by rotating a rotating member such as a van or a rotor by a motor, in particular in the upper and lower directions in both directions A rotating member moving device of a two-way discharge blower capable of improving the blowing efficiency of the blower by allowing the position of the rotating member disposed inside the blower case to be changed according to the condition in which air having a predetermined pressure is discharged. will be.

일반적으로 상부 방향으로 찬공기가 배출되고 하부방향으로 더운 공기가 배출되는 냉난방기와 항온 항습기등에 내장되는 상부와 하부 양방향으로 토출구를 갖는 양방향 토출 송풍기는 제1도 내지 제2도에 도시한 바와 같이 모터(1)의 회전 동력에 의해서 회전되는 회전부재(2)와, 상기 회전부재(2)의 회전에 의해 외부에서 흡입된 공기가 소정의 압력을 갖는 공기로 전환되어서 이 공기가 상부 혹은 하부 방향으로 토출되도록 상부 토출구(3) 및 하부 토출구(4)가 형성된 송풍케이스(5), 그리고 상기 송풍 케이스(5)에 내장되어서 상부 혹은 하부 방향으로 이동 되어서 어느 한쪽 방향의 토출구로 소정의 압력을 갖는 공기가 토출되도록 다른 한쪽 방향의 토출구를 차단하는 막음부재(6)로 이루어져 있다.In general, a two-way discharge blower having discharge openings in both upper and lower directions, which are built in a heating and cooling unit and a constant temperature and humidity chamber, in which cold air is discharged in an upper direction and hot air is discharged in a lower direction, as shown in FIGS. 1 to 2. The rotating member 2 rotated by the rotational power of (1) and the air sucked from the outside by the rotation of the rotating member 2 are converted into air having a predetermined pressure so that the air is moved upward or downward. An air blower case 5 having an upper discharge hole 3 and a lower discharge hole 4 formed therein, and air that is built into the air blower case 5 and is moved upward or downward to have a predetermined pressure to the discharge hole in either direction It consists of a blocking member 6 for blocking the discharge port in the other direction so that the discharge.

이와 같이 이루어진 양방향 토출 송풍기(7)는 송풍케이스(5)에 내장되는 막음부재(6)로 상부 토출구(3) 혹은 하부 토출구(4)의 어느 한쪽 방향의 토출구를 차단함으로써 다른 한쪽 방향의 토출구로 소정의 압력을 갖는 공기가 토출되었다.The bidirectional discharge blower 7 thus constructed is a blocking member 6 embedded in the blower case 5 to block the discharge port in either direction of the upper discharge port 3 or the lower discharge port 4 to the discharge port in the other direction. Air having a predetermined pressure was discharged.

그러나 상기와 양방향 토출 송풍기(7)는 송풍케이스(5)에 형성된 상부 모서리(8)와 회전부재(2) 사이에 발생되는 상부 틈새(a), 및 송풍케이스(5)에 형성된 하부모서리(9)와 회전부재(2) 사이에 발생되는 하부 틈새(b)를 조절할수 없어서 송풍기의 송풍 효율을 향상시키지 못했다.However, the two-way discharge blower 7 has an upper gap a formed between the upper edge 8 formed on the blower case 5 and the rotating member 2, and a lower edge 9 formed on the blower case 5. ), The lower gap b generated between the rotating member 2 and the rotating member 2 could not be adjusted, thereby improving the blowing efficiency of the blower.

즉, 양방향 토출 송풍기(7)는 하부 토출구(4)를 막음부재(6)로 차단하고 상부 토출구(3)로 소정의 압력을 갖는 공기가 토출 되도록 할 경우에는 상부 틈새(a)가 좁고 하부 틈새(b)는 상부 틈새(a) 보다 넓어야 공기의 마찰 손실을 줄여서 송풍기의 송풍 효율이 향상된다.That is, the bidirectional discharge blower 7 blocks the lower discharge port 4 by the blocking member 6 and discharges the air having a predetermined pressure to the upper discharge port 3 so that the upper gap a is narrow and the lower gap is provided. (b) should be larger than the upper gap (a) to reduce the frictional loss of air to improve the blowing efficiency of the blower.

또, 상부 토출구(3)를 막음부재(6)로 차단하고 하부 토출구(4)로 소정의 압력을 갖는 공기가 토출되도록 할 경우에는 하부 틈새(b)가 좁고 상부 틈새(a)는 하부 틈새(b)보다 넓어야 공기의 마찰 손실을 줄여서 송풍기의 송풍 효율을 향상시킬수 있으나 종래의 양방향 토출 송풍기(7)는 상부 틈새(a) 혹은 하부 틈새(b)의 어느 한쪽 틈새를 좁히고 다른 한쪽 틈새를 넓히면 상부 토출구(3) 혹은 하부 토출구(4)의 어느 한쪽 방향의 송풍 효율은 향상될 수 있으나 다른 한쪽 방향의 송풍 효율이 현저히 감소된다.In addition, when the upper discharge port 3 is blocked by the blocking member 6 and air having a predetermined pressure is discharged to the lower discharge port 4, the lower gap b is narrow and the upper gap a is the lower gap ( b) should be wider to improve the blower efficiency of the blower by reducing the friction loss of the air, but the conventional two-way discharge blower (7) by narrowing any one of the upper gap (a) or lower gap (b) and widen the other gap The blowing efficiency in either direction of the discharge port 3 or the lower discharge port 4 can be improved, but the blowing efficiency in the other direction is significantly reduced.

이로 인해서 상기와 같은 양 방향 토출 송풍기(7)는 상부틈새(a)와 하부 틈새(b)를 대체로 일차시켜 사용함으로써 송풍기의 송풍 효율을 보다 향상시킬수 없고 공기 마찰로 소음이 발생된다는 문제점이 있었다.Therefore, the two-way discharge blower 7 as described above has a problem in that noise may be generated by air friction because the upper gap a and the lower gap b are generally used as the primary, and thus the blower efficiency of the blower cannot be further improved.

본 고안은 상술한 문제점을 감안해서 이루어진 것으로써, 본 고안의 목적은 송풍 케이스에 형성된 상부 모서리 및 하부 모서리와 회전부재 사이에 발생되는 상부틈새 및 하부틈새를 공기의 토출 조건에 따라서 가변시킬 수 있도록 하여서 송풍기의 송풍 효율을 향상시킬수 있는 양방향 토출송풍기의 회전부재 이동장치를 제공하는데 있다.The present invention has been made in view of the above-described problems, and an object of the present invention is to allow the upper and lower gaps formed between the upper and lower edges and the rotating member formed in the blower case to be varied according to the discharge conditions of air. It is to provide a rotating member moving device of the two-way discharge blower that can improve the blowing efficiency of the blower.

이와 같은 목적을 달성하기 위하여, 본 고안에 의한 양방향 토출 송풍기의 회전부재 이동장치는 회전부재가 내장되고 상부토출구 및 하부토출구가 형성된 송풍케이스와, 회전부재를 회전시키는 모터로 이루어진 양방향 토출 송풍기에 있어서, 상부 걸림턱 및 하부 걸림턱이 형성된 고정부재와, 상기 고정부재에 형성된 상부 걸림턱 및 하부 걸림턱의 어느 한쪽 걸림턱에 고정되며 모터 및 회전부재가 일체로 이동되도록 지지하는 지지부재와, 상기 고정부재에 지지부재를 고정시키는 고정수단으로 이루어져 공기의 토출 조건에 따라서 상기 회전부재를 이동시켜 송풍 효율을 향상시킬수 있는 것을 특징으로 한다.In order to achieve the above object, the rotating member moving device of the two-way discharge blower according to the present invention is a two-way discharge blower consisting of a blower case with a rotary member is built, the upper discharge port and the lower discharge port is formed, and a motor for rotating the rotating member A fixing member having an upper locking jaw and a lower locking jaw, a supporting member fixed to one of the upper locking jaws and the lower locking jaw formed on the fixing member, and supporting the motor and the rotating member to be integrated with each other; It is made of a fixing means for fixing the support member to the fixing member is characterized in that it is possible to improve the blowing efficiency by moving the rotating member in accordance with the discharge conditions of the air.

이와 같은 구성에 의하면 모타 및 회전부재를 일체로 지지하는 지지부재를 공기의 토출조건에 따라서 고정부재에 형성된 상부 걸림턱 및 하부 걸림턱에 고정수단으로 고정할 수 있으므로 송풍 케이스에 형성된 상부모서리 및 하부모서리와 회전부재 사이에 발생하는 상부틈새 및 하부틈새 조절할 수 있다.According to this configuration, the support member for integrally supporting the motor and the rotating member can be fixed to the upper and lower locking jaws formed on the fixing member according to the discharge conditions of the air by fixing means, so that the upper edge and the lower corner formed on the ventilation case The upper gap and the lower gap between the edge and the rotating member can be adjusted.

즉, 송풍 케이스의 상부 토출구 방향으로 소정의 압력을 갖는 공기를 토출 시킬 경우에는 고정부재에 형성된 상부 걸림턱에 지지부재를 일치시킨 후 고정수단으로 고정부재에 지지부재를 고정 시켜서 상부 틈새를 좁히고 하부 틈새를 넓혀 송풍 효율을 향상시킨다.That is, in the case of discharging air having a predetermined pressure in the direction of the upper discharge port of the blower case, the support member is matched to the upper locking jaw formed in the fixing member, and then the supporting member is fixed to the fixing member by the fixing means to narrow the upper gap and the lower portion. Widen the gap and improve the blowing efficiency.

또, 하부 토출구 방향으로 소정의 압력을 갖는 공기를 토출 시킬 경우에는 고정부재에 형성된 하부 걸림턱에 지지부재를 일치시킨 후 고정수단으로 고정부재에 지지부재를 고정시켜 하부틈새를 좁히고 상부 틈새를 넓혀 송풍 효율을 항상 시킬수 있는 것이다.In addition, in the case of discharging air having a predetermined pressure in the direction of the lower discharge port, the supporting member is matched to the lower locking jaw formed in the fixing member, and then the supporting member is fixed to the fixing member by fixing means to narrow the lower gap and widen the upper gap. Blowing efficiency can always be made.

도면에서 송풍케이스(10)가 모터(30)의 양쪽에 배설되어 있으나 기능이 같으므로 한쪽만을 설명한다.In the drawing, the blower case 10 is disposed on both sides of the motor 30, but functions are the same.

또, 상기 송풍케이스(10)에는 막음부재(13)가 내장되어서 상부 토출구(11) 혹은 하부 토출구(12) 중 어느 한쪽방향 토출구로만 소정의 압력을 갖는 공기가 토출 되도록 상부 토출구(11) 혹은 하부 토출구(12)중 다른 한쪽 방향 토출구를 차단시킨다.In addition, the blower case 10 has a blocking member 13 built therein so that the air having a predetermined pressure is discharged only to one of the upper discharge holes 11 and the lower discharge holes 12 to discharge the air having the predetermined pressure. The ejection openings in the other direction of the ejection openings 12 are blocked.

또, 그림에서 (50)은 상단부로 부터 도시되지 않은 구멍이 형성되어있는 지지부재로써, 모터(30)와, 이 모터(30)의 양단에 돌설된 회전축(31)과, 이 회전축(31)이 원활히 회전되도록 보좌는 베어링부재(40), 그리고 회전축(31)의 단부에 삽입되어서 상기 모터(30)의 회전에 연동되는 회전부재(20)를 일체로 지지한다.In the figure, reference numeral 50 denotes a support member in which a hole, not shown, is formed from the upper end, and includes a motor 30, a rotation shaft 31 protruding from both ends of the motor 30, and the rotation shaft 31. The throne is inserted into the bearing member 40 and the end of the rotating shaft 31 so as to smoothly rotate, and integrally supports the rotating member 20 linked to the rotation of the motor 30.

또한 (60)은 고정부재로써, 상부 걸림턱(61)과 하부 걸림턱(62)이 형성되어 있다.In addition, 60 is a fixing member, the upper locking jaw 61 and the lower locking jaw 62 is formed.

한편, 상기 지지부재(50)의 도시되지 않은 구멍은 상기 고정부재(60)에 형성된 상부 걸림턱(61) 혹은 하부걸림턱(62)의 어느 한쪽 걸림턱과 일치되어 고정수단(70)이 삽입된다.On the other hand, the hole (not shown) of the support member 50 is coincident with either the locking jaw of the upper locking jaw 61 or the lower locking jaw 62 formed in the fixing member 60 to insert the fixing means 70. do.

(제3도에서 고정수단(70)은 볼트와 너트로 도시하였으나, 본 고안은 이에 한정하는 것이 아니라 고정부재(60)에 형성된 걸림턱과 지지부재(50)에 형성된 구멍을 일치시킨 후 멈춤핀 등과 같은 수단을 삽입하여서 고정부재(60)에 지지부재(50)를 고정시킬 수 있는 모든 수단이 적용됨을 물론이다.)(The fixing means 70 in FIG. 3 is shown as a bolt and a nut, but the present invention is not limited thereto, and a stop pin after matching a hole formed in the supporting member 50 with a locking jaw formed in the fixing member 60.

이와 같이 구성된 본 고안은 송풍케이스(10)의 상부 토출구(11)로 공기를 토출시킬 경우에는 막음부재(13)로 하부 토출구(12)를 차단하고 지지부재(50)의 도시되지 않은 구멍을 고정부재(60)의 상부 걸림턱(61)에 일치시킨 후 고정수단(70)으로 고정부재(60)에 지지부재(50)를 고정시키면 모터(30)와 회전부재(20)가 일체로 상부방향으로 이동되어 제5도에 도시한 회전부재(20)의 실선과 같이 송풍 케이스(10)의 상부 모서리(14)와 회전부재(20) 사이의 상부틈새(A)가 좁아지고 송풍케이스(10)의 하부모서리(15)와 회전부재(20) 사이의 하부틈새(B)가 넓어져서 공기의 마찰저항을 최소로하여 송풍 효율을 향상시키고 소음을 감소시킬수 있다.When the air is discharged to the upper discharge port 11 of the blower case 10, the present invention configured as described above blocks the lower discharge port 12 with the blocking member 13 and fixes an unshown hole of the support member 50. When the support member 50 is fixed to the fixing member 60 with the fixing means 70 after matching the upper locking jaw 61 of the member 60, the motor 30 and the rotating member 20 are integrally upwards. The upper gap A between the upper edge 14 of the blower case 10 and the rotatable member 20 is narrowed as shown by the solid line of the rotating member 20 shown in FIG. Lower gap (B) between the lower edge 15 of the rotary member 20 is widened to minimize the frictional resistance of the air to improve the blowing efficiency and reduce the noise.

또 송풍케이스(10)의 하부 토출구(12)로 공기를 토출시킬 경우에는 막음부재(13)로 상부 토출구(11)를 차단하고 지지부재(50)의 도시되지 않은 구멍을 고정부재(60)의 하부 걸림턱(62)에 일치시킨 후 고정수단(70)으로 고정부재(60)에 지지부재(50)를 고정시키면 모터(30)와 회전부재(20)가 일체로 하부 방향으로 이동되어 제5도에 도시한 회전부재(20)의 점선과 같이 상부틈새(A')가 넓어지고 하부틈새(B')가 좁아져서 공기의 마찰저항을 최소로 하여서 송풍 효율을 향상시키고 소음을 감소할 수 있는 것이다.In addition, in the case of discharging air to the lower discharge port 12 of the blower case 10, the upper discharge port 11 is blocked by the blocking member 13, and an unshown hole of the support member 50 is removed from the fixing member 60. When the support member 50 is fixed to the fixing member 60 by the fixing means 70 after matching with the lower locking jaw 62, the motor 30 and the rotating member 20 are integrally moved in the lower direction to form a fifth portion. As shown in the dotted line of the rotating member 20, the upper gap A 'is widened and the lower gap B' is narrowed, thereby minimizing the frictional resistance of air, thereby improving the blowing efficiency and reducing the noise. will be.
