도 1은 종래의 로봇 청소기를 보인 종단면도이다.1 is a longitudinal sectional view showing a conventional robot cleaner.

이에 도시된 바와 같이, 종래의 로봇 청소기는 청소기 본체(1)의 내측에 흡입력을 발생시키기 위한 팬 모터(2)가 장착되어 있고, 그 팬 모터(2)의 전방에는 팬 모터(2)에 의해 흡입되는 먼지나 오물을 집진하는 필터(3)가 내장된 필터 컨테이너(4)가 착,탈가능하게 설치되어 있다.As shown therein, the conventional robot cleaner is equipped with a fan motor 2 for generating a suction force inside the cleaner body 1, and in front of the fan motor 2 by the fan motor 2.

또한, 상기 팬 모터(2)의 하측에는 정,역회전이 가능한 한쌍의 구동바퀴(9)가 일정간격으로 두고 설치되어 있고, 상기 흡입헤드(8)의 후위에는 청소기 본체(1)의 후위를 지지하도록 보조바퀴(10)가 설치되어 있다.In addition, a pair of drive wheels 9 capable of forward and reverse rotation are provided below the fan motor 2 at regular intervals, and the rear of the suction head 8 is provided with the rear of the cleaner body 1. Auxiliary wheel 10 is installed to support.

그리고, 상기 청소기 본체(1)의 후면에는 충전단자(11)를 구비한 충전단자부(12)가 설치되어 있고, 실내의 벽면(13)에 설치된 전원단자부(14)에는 충전단자부(12)에 접속될 수 있도록 접속단자(15)가 구비되어 있어서, 충전단자(11)가 접속단자(15)에 접속된 상태에서 본체(1) 내측의 충전 밧데리(16)에 충전을 할 수 있도록 되어 있다.In addition, a charging terminal unit 12 having a charging terminal 11 is installed at a rear surface of the cleaner main body 1, and a charging terminal unit 12 is connected to a power terminal unit 14 installed at a wall surface 13 in the room. The connection terminal 15 is provided so that the charging battery 16 inside the main body 1 can be charged while the charging terminal 11 is connected to the connection terminal 15.

또한, 상기 청소기 본체(1)의 전면 중앙부에는 초음파를 송신하는 초음파송신부(17)가 설치되어 있고, 그 초음파송신부(17)의 상,하측에는 초음파송신부(17)에서 송신된후 반사되는 초음파를 수신하여 장애물을 감지하기 위한 다수개의 초음파수신부(18)가 일정간격으로 두고 설치되어 있다.  In addition, an ultrasonic transmitter 17 for transmitting ultrasonic waves is provided at the front center portion of the cleaner body 1, and ultrasonic waves transmitted after the ultrasonic transmitter 17 are reflected on the upper and lower sides of the ultrasonic transmitter 17. A plurality of ultrasonic receivers 18 for receiving and detecting obstacles are installed at regular intervals.

그리고, 상기 전원단자부(14)의 하측에는 충전단자부(12)를 전원단자부(14)쪽으로 유도하기 위한 광신호를 발광하는 발광부(19)가 설치되어 있고, 상기 충전단자부(12)의 하측에는 상기 발광부(19)에서 발광되는 광신호를 수광할 수 있도록 수광부(20)가 설치되어 있다.A light emitting unit 19 for emitting an optical signal for guiding the charging terminal unit 12 toward the power terminal unit 14 is provided below the power terminal unit 14, and below the charging terminal unit 12. The light receiving unit 20 is installed to receive the light signal emitted from the light emitting unit 19.

도면중 미설명 부호 21은 제어수단이고, 22는 배기구이다.In the figure, reference numeral 21 denotes a control means, and 22 denotes an exhaust port.

상기와 같은 구성되어 있는 종래의 로봇 청소기를 이용하여 청소를 할때는, 사용자가 동작버튼을 누르면 충전 밧데리(16)의 전원이 팬 모터(2)에 인가되어 팬 모터(2)가 구동이 되어 지는데, 그와 같이 구동되어지는 팬 모터(2)에 의해 필터 컨테이너(4)에 흡입력이 발생되고, 그 흡입력에 의해 바닥(6)의 먼지나 오물이 흡입헤드(8)로 흡입된 후, 흡입관(5)을 통하여 필터(3)에서 포집되어 진다.When cleaning using a conventional robot cleaner configured as described above, when the user presses the operation button, the power of the charging battery 16 is applied to the fan motor 2 to drive the fan motor 2, A suction force is generated in the filter container 4 by the fan motor 2 driven as described above, and dust or dirt on the bottom 6 is sucked into the suction head 8 by the suction force. Is collected by the filter (3).

또한, 제어수단(21)의 제어신호에 의해 구동바퀴(9)를 구동시켜서 청소기 본체(1)를 이동시킴에 따라 일정영역의 청소가 자동으로 이루어지게 된다.In addition, the cleaning of a predetermined area is automatically performed by moving the cleaner body 1 by driving the driving wheel 9 by the control signal of the control means 21.

한편, 자동청소를 수행하는 동안 충전 밧데리(16)의 전압레벨이 도시생략된 전압감지부를 통해 감지되고, 제어수단에서 전압감지부를 통해 감지된 충전 밧데리(16)의 전압레벨이 설정된 소정레벨 이하로 되면 제어수단에 의해 자동청소기의 청소가 정지되는 한편, 제어수단은 현재위치를 내부 메모리에 기억시킨 다음, 메모리에 저장되어 있는 복귀조정에 의해 청소기를 복귀시키기 위한 제어신호를 발생한다.Meanwhile, during the automatic cleaning, the voltage level of the charging battery 16 is detected through the voltage sensing unit, not shown, and the voltage level of the charging battery 16 detected by the voltage sensing unit in the control unit is lower than or equal to the predetermined level. When the cleaning means is stopped by the control means, the control means stores the current position in the internal memory, and then generates a control signal for returning the cleaner by the return adjustment stored in the memory.

따라서, 제어수단의 제어신호에 의해 청소기 본체(1)가 전원단자부(14)측으로 이동되고, 청소기 본체(1)가 전원단자부(14)의 근처에 이르면, 전원단자부(14)의 하측에 설치된 발광부(19)에서 발광되는 광신호가 충전단자부(12)의 하측에 설치된 수광부(20)에서 수광되고, 그 수광부(20)에서 수광되는 광신호에 의해 제어수단이 구동바퀴(9)를 구동제어함으로써, 충전단자부(12)가 전원단자부(14)측으로 접근된다.Therefore, when the cleaner main body 1 is moved toward the power terminal 14 by the control signal of the control means, and the cleaner body 1 reaches the vicinity of the power supply terminal 14, light emission provided under the power supply terminal 14 is emitted. The optical signal emitted from the unit 19 is received by the light receiving unit 20 provided below the charging terminal unit 12, and the control means drives and controls the driving wheel 9 by the optical signal received by the light receiving unit 20. The charging terminal part 12 approaches the power terminal part 14 side.

그 다음, 충전단자부(12)의 충전단자(11)가 전원단자부(14)의 접속단자(15)에 접촉이 되고, 전원단자부(14)에 의해 공급되어지는 전원에 의해 청소기 본체(1) 내의 충전 밧데리(16)의 충전이 이루어진다.Then, the charging terminal 11 of the charging terminal unit 12 is brought into contact with the connection terminal 15 of the power supply terminal unit 14, and the inside of the cleaner main body 1 by the power supplied by the power supply terminal unit 14. The charging battery 16 is charged.

한편, 청소기 본체(1) 내의 충전 밧데리(16)가 충전되는 동안, 전압감지부를 통해 충전 밧데리(16)에 충전되는 전압레벨이 감지되어 제어수단으로 제공되고, 제어수단은 전압감지부를 통해 감지되는 충전 밧데리(16)의 전압레벨이 설정된 소정레벨 이상이 되면 구동바퀴(9)를 구동제어함으로써, 청소기 본체(1)가 전원단자부(14)로부터 분리된 다음, 청소기 본체(1)의 내부 메모리에 저장된 위치로 이동되어 청소작업을 계속 수행하게 된다.On the other hand, while the charging battery 16 in the cleaner body 1 is being charged, the voltage level charged in the charging battery 16 through the voltage sensing unit is detected and provided to the control means, and the control means is sensed through the voltage sensing unit. When the voltage level of the charging battery 16 reaches a predetermined level or more, the drive wheel 9 is driven to be controlled so that the cleaner main body 1 is separated from the power supply terminal unit 14 and then stored in the internal memory of the cleaner main body 1. It will be moved to the saved location to continue cleaning.

그러나, 상기와 같은 종래의 로봇 청소기는 흡입헤드(8)에서 1개의 브러쉬(7)에 의해 바닥(6)에 붙어있는 오물들을 떼어내고, 그와 같이 바닥(6)에서 떼어진 오물들이 먼지와 함께 흡입관(5)의 흡입구를 통하여 흡입되는 형태로서, 먼지는 흡입에 문제가 없으나 바닥(6)에 있는 큰 오물들은 전량 흡입이 되지 못하는 경우가 발생되고, 그와 같은 문제점을 해결키 위해서는 흡입력을 증대시키기 위하여 팬 모터(2)의 용량을 증대시켜야 하므로 그에 따른 제조원가상승 및 소음증가 등의 추가적인 단점들이 발생되는 문제점이 있었다. However, such a conventional robot cleaner removes dirt attached to the bottom 6 by one brush 7 from the suction head 8, and the dirt removed from the bottom 6 is separated from dust and dirt. In the form of suction through the suction port of the suction pipe (5), dust does not have a problem in suction, but the large dirt on the bottom (6) is a case that can not be sucked all the amount, in order to solve such a problem Since the capacity of the fan motor 2 must be increased to increase, there are problems in that additional disadvantages such as manufacturing cost increase and noise increase occur.

상기와 같은 문제점을 감안하여 안출한 본 발명의 목적은 바닥에 붙어있는 오물을 떼어냄과 아울러 바닥에서 수직방향의 흡입구 하측으로 이동하여 흡입되어지도록 함으로써 청소효율을 향상시키도록 하는데 적합한 로봇 청소기의 흡입헤드를 제공함에 있다.The object of the present invention devised in view of the above problems is to remove the dirt attached to the floor and to move underneath the suction port in the vertical direction from the bottom to be sucked by the robot cleaner suitable for improving the cleaning efficiency.

상기와 같이 구성되어 있는 본 발명에 따른 흡입헤드(100)가 장착된 로봇 청소기에서 자동으로 청소가 이루어지는 동작을 설명하면 다음과 같다.Referring to the operation is automatically performed in the robot cleaner equipped with a suction head 100 according to the present invention configured as described above are as follows.

먼저, 사용자가 동작버튼을 누르면 충전 밧데리(16)의 전원이 팬 모터(2)에 인가되어 팬 모터(2)가 구동이 되고, 그와 같이 구동되어지는 팬 모터(2)에 의해 필터 컨테이너(4)에 흡입력이 발생되며, 그 흡입력에 의해 바닥(102)의 먼지나 오물이 흡입헤드(100)로 흡입되어 진다.First, when the user presses the operation button, the power of the charging battery 16 is applied to the fan motor 2 so that the fan motor 2 is driven, and the filter container ( A suction force is generated in 4), and dust or dirt on the bottom 102 is sucked into the suction head 100 by the suction force.

그리고, 상기와 같이 흡입헤드(100)에 흡입력이 발생될 때 구동 모터(111)를 가동시키면, 구동 모터(111)의 회전력이 구동풀리(112)와 종동풀리(113) 및 타이밍벨트(114)로 구성되는 동력전달기구에 통해 각 브러쉬(104)에 전달되어 브러쉬(104)를 회전시킬 수 있다.이때, 2개의 브러쉬(104)를 도 4에서 화살표로 표시한 바와 같이 서로 역방향(좌측 브러쉬는 반시계방향, 우측 브러쉬는 시계방향)으로 회전시키면, 바닥(102)에 부착되어 있는 오물들을 떼어냄과 동시에 흡입관(5)의 흡입구 하측으로 끌어 올려서 흡입관(5)을 통하여 흡입되며, 그와 같이 흡입된 오물들은 필터(3)에서 포집되어 진다.When the driving motor 111 is operated when the suction force is generated in the suction head 100 as described above, the rotational force of the driving motor 111 is driven by the driving pulley 112, the driven pulley 113, and the timing belt 114.
