진공청소기의 브러시 회전제어장치Brush rotation controller of vacuum cleaner

본 발명은 진공청소기에 관한 것으로 특히, 이동레버를 조작하여 모터 축의 구동력을 브러시에 선택적으로 전달되도록 하여, 청소 장소에 따라 사용자가 브러시의 회전 상태를 용이하게 전환시켜 줄 수 있고, 브러시가 회전하지 않을 때에는 벨트가 회전하지 않으므로, 벨트의 마찰이 없어서, 벨트의 수명이 연장되도록 하는 진공청소기의 브러시 회전제어장치에 관한 것이다.The present invention relates to a vacuum cleaner, and in particular, by operating the moving lever to selectively transmit the driving force of the motor shaft to the brush, the user can easily switch the rotation state of the brush according to the cleaning place, the brush does not rotate Since the belt does not rotate when it is not, there is no friction of the belt, it relates to a brush rotation control device of the vacuum cleaner to extend the life of the belt.

종래 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 공회전 되는 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.As shown in FIG. 1, a brush rotation control apparatus of a conventional vacuum cleaner includes a drive motor 2 mounted inside the body 1 and a belt connected to the motor shaft 2a of the drive motor 2. 3), the brush 4 connected to the belt 3 and rotated, the idling 5 fastened to the brush 4 and idling, and the belt 3 is transferred to the idling 5 so that the motor It consists of a belt feeder 6 which prevents the driving force of the shaft 2a from being transmitted to the brush 4.

이러한 종래 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 공회전 되어 구동력이 브러시(4)에 전달되지 않게 된다.As shown in FIG. 1, the brush rotation controller of the conventional vacuum cleaner operates the belt carrier 6 in the direction of the arrow when the user cleans textiles such as a carpet, and brushes the belt 3 at the idling 5. When conveying to (4), the driving force is transmitted to the brush 4 along the belt 3 and rotated, and when the user cleans the floor or the like, the belt carrier 6 is operated in the opposite direction to the arrow to operate the belt 3. When the brush 4 is transferred to the idling 5, the idling 5 is idling so that the driving force is not transmitted to the brush 4.

그러나, 이와 같은 종래 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 vacuum cleaner, when operating the belt carriage to remove the belt to the idling, because the belt carriage is pressurized and conveyed to the belt rotated at high speed, friction occurs, thereby There was a problem that the life is reduced.

본 발명은 상기의 결점을 해소하기 위한 것으로, 이동레버를 조작하여 모터축의 구동력을 브러시에 선택적으로 전달되도록 하여, 청소 장소에 따라 사용자가 브러시의 회전 상태를 용이하게 전환시켜 줄 수 있도록 하는 진공청소기의 브러시 회전제어장치를 제공하고자 한다.The present invention is to solve the above-mentioned drawbacks, by operating the moving lever to selectively transmit the driving force of the motor shaft to the brush, the user can easily switch the rotation state of the brush according to the cleaning place vacuum cleaner To provide a brush rotation control device.

이러한 본 발명은 이동레버에 의하여, 구동 모터의 축에서 연장된 연장마찰체로부터 회전마찰체가 착탈 가능하도록 하여, 구동 모터의 구동력이 브러시에 선택적으로 전달되도록 함으로써 달성된다.This invention is achieved by allowing the rotating friction body to be detachable from the extended friction body extending from the axis of the drive motor by the moving lever, so that the driving force of the drive motor is selectively transmitted to the brush.

도 2는 본 발명의 진공청소기의 회전제어장치에서 모터의 구동력이 브러시에 전달되는 상태를 나타낸 평면도로서, 구동 모터(10)와, 이 구동 모터(10)의 축에서 연장된 곳이 설치되는 연장마찰체(11)와, 이 연장마찰체(11)와의 마찰력에 의해 맞물려 회전되는 회전마찰체(40)와, 이 회전마찰체(40)와 브러시(30) 사이에 동력을 전달하여 주는 벨트(20)와, 상기 회전마찰체(40)를 상기 연장마찰체(11)로부터 분리 가능하도록 하여주는 이동레버(50)와, 이 이동레버(50)가 다시 원래의 위치로 복원되는 것과 상기 회전마찰체(40)와 연장마찰체(11) 사이의 접촉을 돕는 탄성체(60)으로 구성된다.Figure 2 is a plan view showing a state in which the driving force of the motor is transmitted to the brush in the rotation control apparatus of the vacuum cleaner of the present invention, the drive motor 10, the extension extending from the axis of the drive motor 10 is installed A friction friction body 11, a rotating friction body 40 which is rotated in engagement with the frictional force of the extended friction body 11, and a belt which transmits power between the rotation friction body 40 and the brush 30 ( 20), a moving lever 50 which allows the rotary friction body 40 to be detachable from the extension friction body 11, the moving lever 50 is restored to its original position, and the rotary friction It is composed of an elastic body 60 to assist the contact between the sieve 40 and the extended friction body (11).

도 4는 상기 연장마찰체(11)와 상기 회전마찰체(40)를 분리하여 나타낸 도로서, 회전마찰체(40)는 단면으로 도시되어, 그 내부에는 베어링(42)이 구성되어있고, 상기 연장마찰체(11)와 맞물리도록 콘 모양의 홈이 형성되어있음을 나타낸다.4 is a view showing the extended friction body 11 and the rotating friction body 40 separately, the rotating friction body 40 is shown in cross section, the bearing 42 is formed therein, A cone-shaped groove is formed to engage the extension friction body 11.

또한, 도 5는 이동레버(50)의 동작위치와 정지위치를 나타낸 도이며, 상기 이동레버(50)가 좌측 하단에 있는 경우가 동작위치이며, 이 경우에는 도 2에서 표현한 상태와 같이 되며, 반면, 상기 이동레버(50)가 우측 상단에 있는 경우가 정지 위치이며, 이 경우에는 도 3에서 표현한 상태가 된다.In addition, Figure 5 is a view showing the operating position and the stop position of the moving lever 50, the movement lever 50 is in the lower left, the operating position, in this case as shown in Figure 2, On the other hand, the moving lever 50 is located at the upper right corner is the stop position, in this case is a state shown in FIG.

이러한 구성에 의한 작용은, 도 2에서 도시하는 바와 같이, 상기 구동 모터(10)의 구동력이 상기 브러시(30)에 전달되는 상태와, 도 3에서 도시하는 바와 같이, 이동레버(50)의 조작에 의하여 상기 구동 모터(10)의 구동력이 상기 브러시(30)에 전달되지 않는 상태로 나누어 생각 할 수 있다.The effect of this configuration is as shown in FIG. 2, in which the driving force of the drive motor 10 is transmitted to the brush 30, and as shown in FIG. 3, the operation of the moving lever 50. By this, the driving force of the drive motor 10 can be divided into the state that is not transmitted to the brush 30 can be considered.

먼저, 상기 구동 모터(10)의 구동력이 상기 브러시(30)에 전달되는 상태를 설명하면, 도 2에 도시한 바와 같이, 상기 구동 모터(10)의 구동력이 연장축에 부착된 연장마찰체(11)에 전달되고, 이 연장마찰체(11)의 회전력이 이 연장마찰체(11)에 맞물려 돌아가는 회전마찰체(40)에 전달된다. 그리하여, 이 회전마찰체(40)에 벨트가 연결되어 브러시(30)에 상기 회전력이 전달되어, 카펫 등과 같은 직물류의 바닥을 청소할 경우에는 이러한 상태로 동작하게 된다.First, a state in which the driving force of the driving motor 10 is transmitted to the brush 30 will be described. As shown in FIG. 2, an extension friction body (2) in which the driving force of the driving motor 10 is attached to the extension shaft ( 11), the rotational force of the extended friction body 11 is transmitted to the rotating friction body 40 meshed with the extended friction body (11). Thus, when the belt is connected to the rotary friction body 40 and the rotational force is transmitted to the brush 30, it operates in this state when cleaning the bottom of the fabric, such as carpet.

도 3은 이동레버(50)의 조작에 의하여, 상기 구동 모터(10)의 구동력이 브러시(30)에 전달되지 않는 상태를 나타낸 평면도로서, 상기 이동레버(50)를 그림의 오른쪽으로 당겨 고정시킴으로, 상기 연장마찰체(11)와 회전마찰체(40)의 접촉이 분리되어 상기 구동 모터(10)의 구동력은 브러시에 전달되지 않는 상태가 되는 것이다.3 is a plan view showing a state in which the driving force of the drive motor 10 is not transmitted to the brush 30 by the operation of the moving lever 50, by pulling the moving lever 50 to the right of the figure to fix it. The contact between the extended friction body 11 and the rotating friction body 40 is separated so that the driving force of the driving motor 10 is not transmitted to the brush.

이상과 같은 본 발명은 진공청소기의 브러시 회전제어장치로서, 이동레버의 조작에 의하여 모터의 구동력을 브러시에 선택적으로 전달되도록 함으로써, 청소 장소에 따라 사용자가 브러시의 회전상태를 용이하게 전환시켜 줄 수 있고, 브러시가 회전하지 않을 때에는 벨트가 회전하지 않으므로, 벨트의 마찰이 없어서, 벨트의 수명이 연장되도록 하는 효과가 있는 발명인 것이다.The present invention as described above is a brush rotation control device of a vacuum cleaner, by selectively driving the driving force of the motor to the brush by the operation of the moving lever, the user can easily switch the rotation state of the brush according to the cleaning place. And, since the belt does not rotate when the brush does not rotate, there is no friction of the belt, it is an invention that has the effect of extending the life of the belt.
