본 발명은 로봇 청소기에 관한 것으로, 자동으로 조향이 가능한 로봇청소기에 관한 것이다. The present invention relates to a robot cleaner, and to a robot cleaner capable of steering automatically.                         

일반적으로, 로봇 청소기는 사용자가 조작하지 않아도 청소하고자 하는 구역을 스스로 주행하면서 바닥면으로부터 먼지 등의 이물질을 흡입함으로써, 청소하고자 하는 구역을 자동으로 청소하는 기기이다.In general, a robot cleaner is a device that automatically cleans an area to be cleaned by inhaling foreign substances such as dust from the floor while driving the area to be cleaned by a user without a user's manipulation.

이러한 로봇 청소기는 거리센서를 통해 청소구역에 설치된 기구나 사무용품, 벽 등의 장애물까지의 거리를 판별하고, 그 장애물과의 충돌이나 방해를 방지하도록 피해 다니면서 청소구역을 청소하게 된다.The robot cleaner determines the distance to an obstacle such as an apparatus, office equipment, wall, etc. installed in the cleaning area through the distance sensor, and cleans the cleaning area while avoiding collision or interference with the obstacle.

도 1을 참조하면, 종래의 로봇 청소기는, 청소기본체(10)와, 청소기본체(10)의 하부에 설치되는 구동륜(11)과 종동륜(12)을 구비한다. 또한, 청소기본체(10)의 상부에는 리모트컨트롤러와의 신호 송수신을 위한 안테나(13)와, 거리센서(14)가 소정 위치에 설치된다. 또한, 청소기본체(10)의 내부에는 흡입력을 발생시키는 구동모터(미도시)와 이물질 수거통 및 필터 등이 설치된다. 구동모터의 흡입력은 청소기본체(10)의 하부에 설치되는 흡입포트(15)로 전달됨으로서, 청소면상의 먼지 등의 이물질이 흡입력에 의해 흡입포트(15)로 빨려 들어가 제거된다.Referring to FIG. 1, the conventional robot cleaner includes a cleaning main body 10, a driving wheel 11 and a driven wheel 12 installed below the cleaning main body 10. In addition, an antenna 13 and a distance sensor 14 for transmitting and receiving a signal to and from the remote controller are provided at an upper portion of the cleaning main body 10 at a predetermined position. In addition, a driving motor (not shown) generating a suction force, a foreign material container, a filter, and the like are installed inside the cleaning main body 10. The suction power of the drive motor is transmitted to the suction port 15 installed in the lower portion of the cleaning main body 10, whereby foreign matter such as dust on the cleaning surface is sucked into the suction port 15 by the suction force and removed.

그런데, 상기 구성에 의하면, 로봇청소기는 스스로 청소구역을 소정 주행패턴으로 주행하면서 청소면의 이물질을 청소하게 되는데, 흡입포트(15)가 청소기본체(10)의 하부에 설치되어 있기 때문에, 예를 들어 가구 밑의 틈새 등에 쌓인 먼지나 이물질을 청소하기가 힘들다는 문제점이 있다.By the way, according to the above structure, the robot cleaner cleans the foreign matter on the cleaning surface while driving the cleaning zone by itself in a predetermined driving pattern. Since the suction port 15 is provided under the cleaning main body 10, for example, There is a problem that it is difficult to clean the dust or foreign matter accumulated in the gap under the furniture.
