본 고안은 진공청소기의 브러쉬롤러 회전방향 전환장치에 관한 것으로서, 보다 상세하게는 진공청소기의 흡입구 이동에 따라 브러쉬롤로 회전방향을 자동으로 전환시킬 수 있는 브러쉬롤러 회전방향 전환장치에 관한 것이다.The present invention relates to a brush roller rotation direction switching device of a vacuum cleaner, and more particularly, to a brush roller rotation direction switching device that can automatically switch the rotation direction with the brush roll in accordance with the movement of the suction port of the vacuum cleaner.

종래에는 진공청소기의 브러쉬롤러는 모터를 이용하거나 공기흡입력에 의해 한쪽 방향으로만 회전하는 회전날개를 이용하여 회전시키는 방법을 사용하였다.Conventionally, a brush roller of a vacuum cleaner uses a method of rotating by using a motor or a rotary blade rotating only in one direction by an air suction input.

이와 같이 한쪽 방향으로만 회전하는 회전날개를 이용할 경우 브러쉬를 밀거나 당길때 회전 브러쉬롤러의 회전방향은 일정하므로 한쪽방향으로만 힘이 전달되어 청소하는데 힘이 많이 드는 문제가 있었다.As such, when using the rotary blade that rotates in only one direction, when the brush is pushed or pulled, the rotation direction of the rotating brush roller is constant, so that the force is transmitted only in one direction, thus causing a lot of power to clean.

따라서 본 고안은 상기와 같은 제반결점을 감안하여 이루어진 것으로서, 본 고안의 목적은, 진공청소기 흡입구 이동에 따라 브러쉬롤러의 회전방향도 자동으로 전환하는 진공청소기의 브러쉬롤러 회전방향 전환장치를 제공하는데 있다.Therefore, the present invention has been made in view of the above-mentioned shortcomings, and an object of the present invention is to provide a brush roller rotation direction switching device for a vacuum cleaner which automatically switches the rotation direction of the brush roller according to the movement of the vacuum suction port. .

상기의 목적을 달성하기 위해 본 고안은, 흡입구 몸체의 저면에 회동가능하게 돌설되며, 흡입구몸체의 이동방향에 따라 회전방향이 결정되는 바퀴와, 상기 바퀴의 회전축에 결합되어 회전되는 제1치차와, 상기 제1치차와 치합되어 회전되는 제2치차와, 상기 제2치차의 중심축에 결합되어 흡입구의 공기유로를 상하측으로 변경하는 유로변경밸브와, 상기 유로변경밸브의 이동에 따라 변경되는 공기유로로 흡입되는 흡입력에 의해 회전방향이 결정되는 회전날개와, 상기 회전날개의 회전력을 브러쉬롤러의 회전축에 전달하는 구동벨트로 구성된 것을 특징으로 한다.In order to achieve the above object, the present invention rotatably protrudes on the bottom surface of the inlet body, and a wheel having a rotational direction determined according to a moving direction of the inlet body, and a first gear that is coupled to the rotating shaft of the wheel and rotates. And a second gear that is engaged with the first gear and rotates, a flow path change valve coupled to a central axis of the second gear to change an air flow path of the inlet up and down, and air changed according to movement of the flow path change valve. It characterized in that it is composed of a rotary blade that the rotation direction is determined by the suction force sucked into the flow path, and a drive belt for transmitting the rotational force of the rotary blade to the rotating shaft of the brush roller.

이하, 예시된 도면을 통하여 본 고안은 더욱 상세히 설명한다.Hereinafter, the present invention through the illustrated drawings will be described in more detail.

제1도는 본 고안에 따른 장치를 채용한 진공청소기의 회전브러쉬 구조를 나타낸 도면이고, 제2도는 제1도의 A부분을 상세히 나타낸 단면도이다.1 is a view showing a rotating brush structure of a vacuum cleaner employing a device according to the present invention, Figure 2 is a cross-sectional view showing a portion A of FIG.

제1도에서, 참고부호 1은 진공청소기의 흡입구 몸체를 나타낸 것이다. 그리고, 상기 흡입구몸체(1)의 중앙에는 세로 방향으로 브러쉬롤러(10)가 설치된다. 상기 브러쉬롤러(10)는 흡입구몸체(1)의 내면에 설치된 회전축(20)에 회동가능하게 결합되어 있다.In FIG. 1, reference numeral 1 denotes a suction port body of the vacuum cleaner. In addition, the brush roller 10 is installed in the longitudinal direction in the center of the inlet body (1). The brush roller 10 is rotatably coupled to the rotating shaft 20 installed on the inner surface of the suction inlet body (1).

한편, 흡입구몸체(1)의 저면에는, 흡입구몸체(1)의 이동 방향에 따라 회전되는 바퀴(30)가 돌축 형성되어 있다.On the other hand, on the bottom surface of the suction port body 1, the wheel 30 which rotates according to the moving direction of the suction port body 1 is formed in a projection.

제1치차(41)는 제2도에 도시된 바와 같이, 바퀴30)의 회전축(32)에 회동가능하게 결합되고, 제2치차(43)는 상기 제1치차(41)와 치합된다.As shown in FIG. 2, the first gear 41 is rotatably coupled to the rotation shaft 32 of the wheel 30, and the second gear 43 is meshed with the first gear 41.

그리고, 상기 제1 및 제2치차(41)(43)는 상호 지지대(42)에 의해 지지되어 있다.The first and second gears 41 and 43 are supported by mutual support 42.

상기 제2치차(43)의 회전축(43a)에는 제2도에 도시된 바와 같이, 유로변경밸브(44)가 결합되어 있으므로 흡입구의 공기흐름을 제2치차(43)의 회전 방향에 의존하여 변경할 수 있도록 되어 있다.As shown in FIG. 2, the flow change valve 44 is coupled to the rotation shaft 43a of the second gear 43, so that the air flow of the intake port is changed depending on the rotation direction of the second gear 43. It is supposed to be.

한편, 회전날개(46)는 제2도에 도시된 바와 같이, 상기 유로변경밸브(44)의 이동에 따라 변경되는 공기 유로 흡입되는 흡입력에 의해 회전방향이 결정되도록 흡입구에 설치되어 있다.On the other hand, as shown in Figure 2, the rotary blade 46 is installed in the inlet so that the rotation direction is determined by the suction force sucked in the air flow path changed in accordance with the movement of the flow path change valve 44.

상기 회전날개(46)의 회전축(48)과 브러쉬롤러(10)의 회전축(20)에는 회전날개(46)의 회전력을 브러쉬롤러(10)에 전달하도록 구동밸브(50)가 설치되어 있다.The driving valve 50 is installed on the rotary shaft 48 of the rotary blade 46 and the rotary shaft 20 of the brush roller 10 so as to transmit the rotary force of the rotary blade 46 to the brush roller 10.

상기한 바와 같은 구조로된 브러쉬롤러 회전방향 전환장치를 채용한 진공청소기의 흡입구몸체(1)를 밀거나 또는 당기게 되면 상기 흡입구몸체(1)의 저면에 돌출형성된 바퀴30)는 흡입구몸체(1)의 이동방향으로 움직이게 된다.When pushing or pulling the inlet body 1 of the vacuum cleaner employing the brush roller rotation direction switching device having the structure as described above, the wheel 30 protruding from the bottom of the inlet body 1 is the inlet body 1. It moves in the direction of movement of.

이와 같이 바퀴30)가 움직이게 되면, 상기 바퀴30)의 회전축(32)에 결합되어 있는 제1치차(41)가 회전하게 되므로 이와 연동되는 제2치차(43)도 회전하게 된다.When the wheel 30 moves as described above, the first gear 41 coupled to the rotation shaft 32 of the wheel 30 rotates, such that the second gear 43 interlocked with the wheel 30 rotates.

상기 제2치차(43)는 그 외주연의 1/4에 해당되는 부분에 치(齒)가 형성되므로 제1치차(41)가 계속 회전하여도 90°이상은 회전되지 않게 된다.Since the teeth are formed in a portion corresponding to a quarter of the outer circumference of the second gear 43, the second gear 43 is not rotated by more than 90 ° even if the first gear 41 continues to rotate.

따라서, 제1치차(41)가 흡입구몸체(1)의 이동에 따라 계속 회전하여도 제2치차(43)는 90°정도 회전하게 되므로 상기 제2치차(43)의 중심축에 결합되어 있는 유로변경밸브(44)는 흡입구 내면에 설치되어 있는 걸림턱(1a)(1b)까지 회전하게 되어 흡입구의 공기 유로를 상측 또는 하측으로 분리하게 된다.Therefore, even if the first gear 41 continues to rotate in accordance with the movement of the inlet body 1, the second gear 43 rotates about 90 °, so that the flow path is coupled to the central axis of the second gear 43. The change valve 44 is rotated up to the engaging jaw (1a) (1b) installed on the inner surface of the inlet port to separate the air flow path of the inlet port to the upper side or the lower side.

예를들어, 상기 유로변경밸브(44)가 시계방향으로 90°회전하게 되면 흡입구의 공기유로가 하측으로 형성되므로 회전날개(46)는 시계반대방향으로 회전하게 된다.For example, when the flow path change valve 44 rotates 90 ° clockwise, the air flow path of the inlet port is formed downward so that the rotary blade 46 rotates counterclockwise.

상기 회전날개(46)가 시계반대방향으로 회전하게 되면, 상기 회전날개축(48)과 구동밸브(50)로 결합되어져 있는 브러쉬롤러의 회전축(20)은 시계방향으로 회전되어 결국 흡입구 몸체가 이동되는 방향으로 브러쉬롤러(10)가 회전하게 된다.When the rotary blade 46 is rotated in the counterclockwise direction, the rotary shaft 20 of the brush roller coupled to the rotary blade shaft 48 and the drive valve 50 is rotated clockwise to eventually move the suction inlet body Brush roller 10 is rotated in the direction.

전술한 바와 같이 구성된 본 고안은 흡입구 몸체의 이동방향에 따라 브러쉬롤러의 회전방향으로 자동으로 전환하여 사용자가 흡입구 몸체를 밀거나 당길때 힘이 들지 않으므로 사용하기 편리한 잇점이 있다.The present invention configured as described above has an advantage that it is convenient to use because it does not take force when the user pushes or pulls the inlet body by automatically switching to the rotational direction of the brush roller according to the moving direction of the inlet body.
