직립형 진공청소기의 브러시 회전제어장치Brush rotation controller of upright vacuum cleaner

본 발명은 직립형 진공청소기에 관한 것으로, 특히 레버를 조작하여 모터축의 구동력을 브러시에 선택적으로 전달되도록 하는 회전제어부를 구성하여 청소 장소에 따라 사용자가 브러시의 회전상태를 용이하게 전환시켜 줄 수 있도록 하는 직립형 진공청소기의 브러시 회전제어장치에 관한 것이다.The present invention relates to an upright vacuum cleaner, and in particular, to configure the rotation control unit to selectively drive the driving force of the motor shaft to the brush by operating the lever to allow the user to easily switch the rotation state of the brush according to the cleaning location It relates to a brush rotation control device of an upright vacuum cleaner.

종래 직립형 진공청소기의 브러시 회전제어장치는 도 1 에 도시한 바와 같이, 몸체(1)의 내부에 장착되는 구동모터(2)와, 이 구동모터(2)의 모터축(2a)에 연결되는 벨트(3)와, 이 벨트(3)에 연결되어 회동되는 브러시(4)와, 이 브러시(4)에 체결되어 공회전되는 아이들링(5)과, 이 아이들링(5)에 벨트(3)를 이송시켜 모터축(2a)의 구동력이 브러시(4)에 전달되지 않게 하는 벨트이송대(6)로 구성되어있다.Brush rotation control device of a conventional upright vacuum cleaner, as shown in Figure 1, the drive motor 2 is mounted to the inside of the body (1), the belt connected to the motor shaft (2a) of the drive motor (2) (3), a brush (4) connected to the belt (3) and rotated, an idling (5) fastened to this brush (4) and idling, and the belt (3) is transferred to the idling (5). The belt feeder 6 is configured to prevent the driving force of the motor shaft 2a from being transmitted to the brush 4.

이러한 종래 직립형 진공청소기의 브러시 회전제어장치는 도 1 에 도시한 바와 같이, 사용자가 카펫 등의 직물류를 청소할 경우에 벨트이송대(6)를 화살표방향으로 작동시켜 벨트(3)를 아이들링(5)에서 브러시(4)에 이송시키면, 구동력이 벨트(3)를 따라 브러시(4)에 전달되어 회전되고, 사용자가 마루 등을 청소할 경우에는 벨트이송대(6)를 화살표 반대방향으로 작동시켜 벨트(3)를 브러시(4)에서 아이들링(5)에 이송시키면, 이 아이들링(5)이 공회전되어 구동력이 브러시(4)에 전달되지 않게 되어있다.The brush rotation control device of the conventional upright vacuum cleaner, as shown in Figure 1, when the user cleans the fabrics, such as carpet, by operating the belt carrier 6 in the direction of the arrow to move the belt 3 in the idling (5) When transferred to the brush 4, the driving force is transmitted to the brush 4 along the belt 3 and rotated, and when the user cleans the floor, the belt carrier 6 is operated in the opposite direction to the arrow to the belt 3 Is transferred from the brush 4 to the idling 5, the idling 5 is idling and the driving force is not transmitted to the brush 4.

그러나, 이와 같은 종래 직립형 진공청소기의 브러시 회전제어장치는, 벨트를 아이들링에 착탈시키고자 벨트이송대를 작동시킬 경우, 고속으로 회전되는 벨트에 벨트이송대가 가압되어 이송시키므로 마찰이 발생되었고, 이로 인하여 벨트의 수명이 저하되는 문제점이 있었다.However, the brush rotation control device of the conventional upright vacuum cleaner, when the belt carrier is operated to detach the belt to the idling, the belt carrier is pressed by the belt that is rotated at a high speed to transfer the friction, thereby causing the belt There was a problem that the service life of the.

본 발명은 상기의 결점을 해소하기 위한 것으로, 레버의 조작으로 모터축에 연결된 벨트가 공회전 되도록하여, 브러시에 구동력이 전달되지 않도록 함으로, 사용자의 선택에 따라 모터축의 구동력이 브러시에 선택적으로 전달되도록 하여, 청소 장소에 따라 사용자가 브러시의 회전상태를 용이하게 전환시켜 줄 수 있는 진공청소기의 브러시 회전제어장치를 제공하고자 한다.The present invention is to solve the above-mentioned drawback, the belt connected to the motor shaft by the operation of the lever so that the driving force is not transmitted to the brush, so that the driving force of the motor shaft is selectively transmitted to the brush according to the user's selection In order to provide a brush rotation control apparatus for a vacuum cleaner that allows the user to easily switch the rotation state of the brush according to a cleaning place.

이러한 본 발명은 레버를 조작하면 회전판이 회전하여 링크가 아이들링 풀리를 당기게 되고, 이 아이들링 풀리가 벨트를 당기게 하여 모터의 구동축이 공회전하게 함으로써 달성된다.This invention is achieved by operating the lever to rotate the rotating plate so that the link pulls the idling pulley, which causes the idling pulley to pull the belt so that the drive shaft of the motor idles.

본 발명의 실시예를 첨부 도면을 참고하여 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 구성 및 상호 작용을 나타내는 평면도이며, 도 3은 이에 대한 분해사시도이며, 상기 도 2 및 도 3에서 보는 바와 같이, 구동 모터(10)와, 이 구동 모터(10)의 구동축(11)과, 이 구동축을 구동력을 전달하는 벨트(20)와, 이 벨트(20)에 의해 구동력을 전달받아 회전하는 브러시(30)로 기본 구성된다.Figure 2 is a plan view showing the configuration and interaction of the present invention, Figure 3 is an exploded perspective view thereof, as shown in Figures 2 and 3, the drive motor 10 and the drive shaft of the drive motor 10 (11), the belt 20 which transmits a driving force to this drive shaft, and the brush 30 which receives a driving force by this belt 20, and rotates.

여기에 레버(70)에 의해 회전하는 회전판(50)과, 상기 회전판(50)에 연결되어 회전판(50)의 회전운동을 직선운동으로 전환하는 링크(60)와, 이 링크(60)의 끝에 부착되어 벨트와 함께 회전하는 아이들링 풀리(12)와, 상기 회전판(50)이 볼트(53)와 너트(54)에 의해 부착되고 링크(60) 및 아이들링 풀리(12)가 직선운동 할 수 있는 홈(41)이 형성된 고정판(40)과, 상기 레버(70)가 당겨졌을 때, 상기 회전판(50)을 지지해 주는 스토퍼(51)로 회전제어부가 구성된다.Here, the rotary plate 50 rotated by the lever 70, the link 60 is connected to the rotary plate 50 to convert the rotational movement of the rotary plate 50 to linear movement, and the end of the link 60 An idling pulley 12 that is attached and rotates together with a belt, and the rotary plate 50 is attached by bolts 53 and nuts 54 and a groove in which the link 60 and the idling pulley 12 can linearly move. The rotation control part is comprised by the fixed plate 40 in which 41 was formed, and the stopper 51 which supports the said rotating plate 50 when the lever 70 is pulled out.

이러한 구성에 의한 작용을 도 4 및 도 5를 참고하여 설명하면 다음과 같다.The operation by this configuration will be described with reference to FIGS. 4 and 5 as follows.

도 4는 기본적인 동작에서의, 즉 카펫 등과 같이 직물류의 바닥을 청소할 경우 브러시가 회전하는 상태를 나타내는 도로서, 레버(70)가 상단에 위치할 경우에, 아이들링 풀리(12)가 모터(10)의 구동축(11: 도 5 참조)과 동축상에서, 벨트(20)에 상기 구동축(11)과 함께 물려 회전하는 상태이다.FIG. 4 is a view showing a state in which the brush rotates when the bottom of the fabric is cleaned, such as a carpet, in a basic operation. When the lever 70 is positioned at the top, the idling pulley 12 is connected to the motor 10. Coaxially with the drive shaft 11 (see FIG. 5), the belt 20 is in a state of being bitten together with the drive shaft 11.

도 5는 마루 등을 청소할 경우, 브러시가 회전하지 않는 상태를 나태낸 도로서,레버(70)가 하단에 위치하게 되면, 회전판(50)이 고정판(40)에서 일정 각도(대략 90°정도)회전하게 되며, 그 상태에서 상기 회전판(50)이 스토퍼(51)에 의해 정지되고, 상기 회전운동은 링크(60)에 의해 직선운동으로 전환되어 아이들링 풀리(12)를 고정판에 형성된 홈(41)을 따라 도 5의 P 지점에서 P' 지점으로 이동시키게 된다. 그리하여 상기 아이들링 풀리(12)가 벨트(20)을 당기게 되어 도 5로 표현된 상태가 되므로, 모터축(11)은 공회전하게 되고, 따라서 모터축(11)의 구동력은 브러시로 전달되지 않는 상태가 된다.5 is a view showing a state in which the brush does not rotate when cleaning the floor, etc., when the lever 70 is located at the bottom, the rotating plate 50 is a certain angle (about 90 degrees) from the fixed plate 40 The rotating plate 50 is stopped in that state by the stopper 51, the rotary motion is converted to a linear motion by the link 60 to form the idle pulley 12 in the fixed plate 41 Therefore, it moves from the point P of FIG. 5 to the point P '. Thus, since the idling pulley 12 pulls the belt 20 to the state represented by FIG. 5, the motor shaft 11 idles, and thus the driving force of the motor shaft 11 is not transmitted to the brush. do.

이상과 같이, 본 발명은 직립형 진공청소기의 브러시 회전 제어장치로서, 레버의 조작에 의한 아이들링 풀리의 작동으로, 모터축에 연결된 벨트가 모터축과 분리되고, 이로 인하여 모터의 구동축이 공회전 되도록 하여, 브러시에 구동력이 전달되지 않도록 함으로써, 청소 장소에 따라 사용자가 브러시의 회전상태를 용이하게 전환시켜 줄 수 있는 효과가 있는 발명인 것이다.As described above, the present invention is a brush rotation control device of an upright vacuum cleaner, by the operation of the idling pulley by the operation of the lever, the belt connected to the motor shaft is separated from the motor shaft, thereby causing the drive shaft of the motor to idle, By not transmitting the driving force to the brush, the invention is an effect that the user can easily switch the rotation state of the brush according to the cleaning place.
