The inclined surface portion 45 prevents the edge of the flow passage 22 from being caught when the opening / closing member 44 is turned clockwise or counterclockwise.

구동부(46)는 유로(22)를 차단하도록 개폐부재(44)를 구동한다.The driving unit 46 drives the opening and closing member 44 to block the flow passage 22.

구동부(46)는 개폐부재(44)의 원주 둘레를 따라 형성되어 개방부(42)를 통해 외측으로 돌출되는 피동기어부(47)와, 피동기어부(47)에 치합되어 개폐부재(44)를 구동하여 유로(22)의 개방량을 조절하는 구동기어(48)와, 구동기어(48)에 결합되어 동력을 제공하는 회전모터(49)를 포함한다.The driving part 46 is formed along the circumference of the opening / closing member 44 and is engaged with the driven gear portion 47 and the driven gear portion 47 protruding outward through the opening portion 42 to open / close the member 44. It includes a drive gear 48 for adjusting the opening amount of the flow path 22 to drive the rotary motor 49 is coupled to the drive gear 48 to provide power.

피동기어부(47)는 개방부(42)를 통해 구동기어(48)의 치에 맞물리도록 충분한 돌출 길이를 갖는 기어치로 이루어진다.The driven gear portion 47 consists of a gear tooth having a protruding length sufficient to engage the teeth of the drive gear 48 through the opening portion 42.

팬하우징(20) 내에는 개폐부재(20)의 이동을 안내하는 가이드부(50)가 구비된다. 가이드부(50)는 구동부(46)에 의해 슬라이드 동작하는 개폐부재(44)가 좌우 유동 없이 안정적으로 슬라이드 이동하도록 안내한다.The fan housing 20 is provided with a guide unit 50 for guiding the movement of the opening and closing member 20. The guide part 50 guides the opening / closing member 44 which slides by the drive part 46 to slidably move without lateral flow.

가이드부(59)는 개폐부재(20)의 양측 테두리에 구비되는 가이드돌부(52)와, 팬하우징(20)의 내측 둘레면에 마련되고, 가이드돌부(52)가 삽입되어 개폐부재(44)의 이동을 안내하는 가이드홈부(54)를 포함한다.The guide portion 59 is provided on the guide protrusions 52 provided on both edges of the opening and closing member 20, and on the inner circumferential surface of the fan housing 20, and the guide protrusion 52 is inserted to open and close the opening member 44. Guide groove 54 for guiding the movement of the.

가이드돌부(52)는 개폐부재(20)의 테두리 일부를 감싸도록 ㄷ자 또는 ㄱ자 형상으로 절곡 형성된다. 가이드돌부(52)는 연속 또는 비연속적으로 형성될 수 있다.Guide protrusions 52 are formed to be bent in the U-shaped or c-shape to surround a portion of the edge of the opening and closing member 20.

가이드홈부(54)에는 개폐부재(44)의 앙측면과 밀착되어 시일링하는 시일링부재(56)가 구비된다. 시일링부재(56)는 고무재 또는 연질의 합성수지재로 이루어지므로 개폐부재(44)의 양 측면과 충분한 접촉이 이루어져 냉기가 누설되는 것을 방지한다.
The guide groove 54 is provided with a sealing member 56 in close contact with the lateral side of the opening and closing member 44 to seal. Since the sealing member 56 is made of a rubber material or a soft synthetic resin material, sufficient contact is made with both sides of the opening and closing member 44 to prevent cold air from leaking.

이하, 첨부도면을 참조하여 본 발명의 일 실시 예에 따른 슬라이드 개폐형 팬조립체의 작용을 살펴보도록 한다.Hereinafter, with reference to the accompanying drawings to look at the action of the slide opening and closing fan assembly according to an embodiment of the present invention.

도 6(a)에 도시된 바와 같이, 회전모터(49)를 반 시계방향으로 회전하면, 구동기어(48)에 치합된 피동기어부(47)가 시계방향으로 회전하면서 개폐부재(44) 역시 시계방향으로 회전한다. As shown in FIG. 6 (a), when the rotary motor 49 is rotated counterclockwise, the driven gear part 47 engaged with the drive gear 48 rotates clockwise while the opening / closing member 44 is also rotated. Rotate clockwise.

연이어, 개폐부재(44)의 좌측단부가 제1유로(22a)의 개폐량을 조절함에 따라 제1저장실(12)로 공급되는 냉기량을 조절하게 된다. 이때, 제2유로(22b)는 개방되어져 있으므로 제2저장실(14)로 공급되는 냉기는 그대로 유지되고, 제1저장실(12)로 공급되는 냉기만 조절되는 것이다.Subsequently, the left end of the opening and closing member 44 adjusts the opening and closing amount of the first flow passage 22a to adjust the amount of cold air supplied to the first storage chamber 12. At this time, since the second passage 22b is open, the cold air supplied to the second storage chamber 14 is maintained as it is, and only the cold air supplied to the first storage chamber 12 is controlled.

만약, 개폐부재(44)를 시계방향으로 더 회전하게 되면, 제1유로(22a)가 완전차단되면서, 제2유로(22b)의 개폐량을 조절함에 따라 제1저장실(12)은 차단되고, 제2저장실(14)은 조절된다.If the opening and closing member 44 is further rotated in the clockwise direction, while the first passage 22a is completely blocked, the first storage chamber 12 is blocked by adjusting the opening / closing amount of the second passage 22b. The second storage compartment 14 is adjusted.

한편, 도 6(b)에 도시된 바와 같이, 회전모터(49)를 시계방향으로 회전하면, 구동기어(48)에 치합된 피동기어부(47)가 반 시계방향으로 회전하면서 개폐부재(44) 역시 반 시계방향으로 회전한다.On the other hand, as shown in Figure 6 (b), when the rotary motor 49 is rotated in the clockwise direction, the driven gear portion 47 meshed with the drive gear 48 rotates in the counterclockwise direction, opening and closing member 44 ) Also rotates counterclockwise.

연이어, 개폐부재(44)의 우측단부가 제2유로(22b)의 개폐량을 조절함에 따라 제2저장실(14)로 공급되는 냉기량을 조절하게 된다. 이때, 제1유로(22a)는 개방되어져 있으므로 제1저장실(12)로 공급되는 냉기는 그대로 유지되고, 제2저장실(14)로 공급되는 냉기만 조절하게 되는 것이다.Subsequently, the right end of the opening and closing member 44 adjusts the opening and closing amount of the second flow passage 22b to adjust the amount of cold air supplied to the second storage chamber 14. At this time, since the first passage 22a is open, the cold air supplied to the first storage chamber 12 is maintained as it is, and only the cold air supplied to the second storage chamber 14 is controlled.

만약, 개폐부재(44)를 반 시계방향으로 더 회전하게 되면, 제2유로(22b)가 완전 차단되면서, 제1유로(22a)의 개폐량을 조절함에 따라 제2저장실(14)은 차단되고, 제1저장실(12)은 조절된다.If the opening / closing member 44 is further rotated counterclockwise, the second passage 22b is completely blocked, and the second storage compartment 14 is shut off by adjusting the opening / closing amount of the first passage 22a. , The first storage chamber 12 is adjusted.

이와 같이, 개폐부재(44)의 회전에 따라 4가지 타입의 개폐량 조절이 신속하게 이루어짐으로써 제품의 신뢰성을 제공할 수 있다.
In this way, according to the rotation of the opening and closing member 44 it is possible to provide the reliability of the product by adjusting the four types of opening and closing quickly.
