본 발명은 진공청소기 흡입구의 스위퍼 가변구동장치에 관한 것으로 특히 흡입구의 전·후진에 따라 먼지 수집장치인 스위퍼(sweeper)가 가변하도록 한 것이다.The present invention relates to a sweeper variable drive device of a vacuum cleaner suction port so that a sweeper, which is a dust collecting device, is variable according to the forward and backward movement of the suction port.
종래 진공청소기의 흡입구는 제1도와 같이 흡입구(1)의 저면에 팬모터의 구동에 따라 발생된 흡입력에 의하여 먼지가 흡입되는 흡입유로입구(2)와, 청소시 흡입구(1)의 이동을 원활하도록 하는 바퀴(3)와, 흡입구(1)가 이동하면서 바닥의 먼지를 쓸어 주는 스위퍼(4)가 일직선으로 고정되게 구성되었다.The suction port of the conventional vacuum cleaner, as shown in FIG. 1, smoothly moves the suction channel inlet 2 through which the dust is sucked by the suction force generated by the driving of the fan motor on the bottom of the suction port 1, and moves the suction port 1 during cleaning. The wheel 3 and the sweeper 4 sweeping the floor dust while the suction port 1 moves are configured to be fixed in a straight line.
이와 같이 구성된 상태에서 청소를 하게 되면 청소성능은 통상적으로 흡입구(1) 바닥의 압력분포와 풍량에 따라 변화하게 된다.When the cleaning in the state configured as described above, the cleaning performance is usually changed according to the pressure distribution and air volume of the bottom of the inlet (1).
즉, 제2도와 같이 임의의 한 지점에 대해 풍량증가시의 (a)와 같이 부압(-)이 점차 커지게 되며, (b)와 같이 청소성능이 향상되는 것을 알 수 있다.That is, as shown in FIG. 2, the negative pressure (-) gradually increases as shown in (a) at the time of increasing the air volume, and the cleaning performance is improved as shown in (b).
이는 임의의 지점을 통과하는 유체의 속도가 증가하기 때문에 흡입구(1) 바닥의 압력분포는 제3도와 같이 나타날 수 있으며, 각 영역의 압력을 평균압력으로 나타내면 제3도 (b)의 표와 같다.This is because the velocity of the fluid passing through any point increases, the pressure distribution at the bottom of the inlet 1 may be shown in Fig. 3, and the pressure in each area is represented by the average pressure as shown in the table of Fig. 3 (b). .
즉, 흡입구 외각은 대기압과 같지만 흡입유로 입구(2)로 갈수록 점차 부압(-)이 증가된다.That is, the outside of the suction port is equal to the atmospheric pressure, but the negative pressure (−) gradually increases toward the suction flow path inlet 2.
그리고, 스위퍼(4)가 설치되면 4면으로 유입되는 공기는 한면이 차단되기 때문에 3면의 공기유입은 각 영역별 풍속의 증가가 나타나서 부압(-)의 증가를 초래하여 청소효율이 향상되었다.In addition, when the sweeper 4 is installed, the air flowing into the four sides is blocked, so that the air inflow on the three sides increases the wind speed for each region, resulting in an increase in the negative pressure (−), thereby improving the cleaning efficiency.
즉, 제4도에서와 같이 전진하면서 청소하는 (a)의 경우는 스위퍼(4)가 쓸어가면서 흡입에만 의해 청소되지 않은 먼지나 쓰레기를 청소가 가능하도록 해 주었는데, 상기 스위퍼(4)가 고정되어 있어서 전진 청소시는 이상없지만 후진 청소시에는 청소가 되지 않는 문제점이 있다.That is, in the case of (a) cleaning while advancing as shown in FIG. 4, the sweeper 4 sweeps away to allow cleaning of dust or garbage that has not been cleaned by suction, but the sweeper 4 is fixed. There is no problem when cleaning the forward but there is a problem that does not clean when cleaning the reverse.
따라서, (b)와 같이 후진 청소시에는 스위퍼(4)가 앞에서 먼지나 쓰레기를 쓸고 가기 때문에 청소가 되지 않아서 전·후진시의 청소효율이 다르게 되며 후진 청소후 전진 청소로 전환되면 스위퍼(4)에 의해 쓸려진 미물질들이 청소가 되지 않고 바닥에 그대로 남게 되는 문제점이 있었다.Therefore, as in (b), when the reverse cleaning is performed, the sweeper 4 sweeps dust or garbage from the front, so the cleaning efficiency is different because the sweeper 4 does not clean and the sweeper 4 changes to the forward cleaning after the reverse cleaning. There was a problem that the beautiful materials washed by the remains on the floor without being cleaned.
본 발명은 이러한 점을 감안하여 흡입구의 저면에 흡입구의 전후진에 따라 가변하는 스위퍼를 장착함으로써 흡입구의 진행방향에 따라 전·후 스위퍼가 바닥에 닿아 항상 일면이 차단되는 효과를 가져옴으로써 부압이 증가하여 청소 효율을 향상시키는 데 그 목적이 있다.In view of the above, the present invention is equipped with a sweeper that is variable according to the forward and backward movement of the suction port on the bottom of the suction port, so that the negative pressure increases as the sweeper touches the floor according to the traveling direction of the suction port, thereby always blocking one surface. The purpose is to improve the cleaning efficiency.

Pushed back.
따라서, 축(110')의 일단이 삽입되어진 안내홈(109)을 따라 이동하게 되는데, 이때 안내홈(109)의 양단이 상방향으로 향하게 구성되어져 있기 때문에 축(110')이 후단쪽으로 이동하게 되어 틀(105)의 후단부가 아래로 기울어진다.Accordingly, one end of the shaft 110 'is moved along the guide groove 109 into which the shaft 110' is inserted. At this time, since both ends of the guide groove 109 are configured to face upward, the shaft 110 'is moved toward the rear end. The rear end of the mold 105 is inclined downward.
이와 같이 틀(105)의 후단부가 기울어짐과 더불어 후단부에 형성된 후면부 스위퍼(107)가 홈(103)을 통과하여 바닥면에 닿아 이동하면서 먼지를 쓸어 모아 흡입구(101)의 바닥면에 형성된 흡입유로 입구로 흡입되도록 한다.As described above, the rear end portion of the mold 105 is inclined and the rear side sweeper 107 formed at the rear end moves through the grooves 103 to reach the bottom surface, sweeps dust and collects the suction formed on the bottom surface of the suction port 101. Allow suction to flow inlet.
그리고, 제8도의 (b)와 같이 뒤로 후진시키면 바퀴(110)가 굴러감과 더불어 앞쪽으로 밀리면서 바퀴(110)에 형성된 축(110')을 따라 앞으로 밀려가게 된다.Then, when the back backward as shown in (b) of FIG. 8, the wheel 110 is pushed forward along with the shaft 110 ′ formed on the wheel 110 while being pushed forward.
따라서 축(110')의 일단이 삽입되어진 안내홈(109)을 따라 이동하게 되는데, 이때 안내홈(109)의 양단이 상방향으로 향하게 구성되어져 있기 때문에 축(110')이 전단쪽으로 이동하게 되어 틀(105)의 전단부가 아래로 기울어진다.Accordingly, one end of the shaft 110 'is moved along the guide groove 109 into which the shaft 110' is inserted. Since both ends of the guide groove 109 are configured to face upward, the shaft 110 'is moved toward the front end. The front end of the mold 105 is inclined downward.
이와 같이 틀(105)의 전단부가 기울어짐과 더불어 전단부에 형성된 전면부 스위퍼(106)가 홈(103)을 통과하여 바닥면에 닿아 이동하면서 먼지를 쓸어 모아 흡입구(101)의 바닥판에 형성된 흡입유로 입구를 통하여 흡입되도록 하는 것이다.As described above, the front end of the mold 105 is inclined, and the front side sweeper 106 formed at the front end moves through the grooves 103 to reach the bottom surface, sweeps dust and is formed on the bottom plate of the suction port 101.
