일반적으로 상기 드럼(5)은 의류건조기나 세탁기에서 쓰이는 것이므로 자세한 설명은 생략한다.In general, since the drum 5 is used in a clothes dryer or a washing machine, a detailed description thereof will be omitted.

도 2에 도시된 바와 같이, 상기 드럼(5)의 외주면에는 일정 간격을 두고 다수개의 홈(1,2,3,4)이 형성된다.As shown in FIG. 2, a plurality of grooves 1, 2, 3, and 4 are formed on the outer circumferential surface of the drum 5 at regular intervals.

상기 홈(1,2,3,4)은 제1홈(1), 제2홈(2), 제3홈(3), 제4홈(4)으로 총 네 개로 구성된다.The grooves 1, 2, 3, and 4 are composed of four grooves including a first groove 1, a second groove 2, a third groove 3, and a fourth groove 4.

상기 홈(1,2,3,4)은 각각 두 개씩 나뉘어서 서로 대칭되도록 형성된다.The grooves 1, 2, 3, and 4 are divided into two and formed to be symmetrical with each other.

상기 제1홈(1) 및 제2홈(2)은 후술할 돌출부(7)의 일측에 배치되고, 상기 제3홈(3)과 제4홈(4)은 돌출부(7)의 타측에 배치된다.The first groove 1 and the second groove 2 are disposed on one side of the protrusion 7 to be described later, and the third groove 3 and the fourth groove 4 are disposed on the other side of the protrusion 7. do.

상기 제1홈(1)과 제2홈(2)의 사이와 제3홈(3)과, 제4홈(4)의 사이의 간격(I)은 짧게 형성된다.The distance I between the first groove 1 and the second groove 2, the third groove 3, and the fourth groove 4 is short.

또한, 제1홈과 제3홈(3)의 사이와, 제2홈(2)과, 제4홈(4)의 사이의 간격(I')은 길게 형성된다.In addition, the interval I 'between the first groove and the third groove 3, the second groove 2, and the fourth groove 4 is long.

상기 드럼(5)의 상부 일측에는 상기 드럼(5)의 회전방향을 감지하도록 구성된 포토커플러(6A,6B)가 연결된다.The upper one side of the drum 5 is connected to the photocoupler (6A, 6B) configured to detect the rotation direction of the drum (5).

상기 포토커플러(6A,6B)는 옵티컬센서 라고도 불리며, 발광소자(6A)와, 수광소자(6B)로 구성된다.The photocouplers 6A and 6B are also called optical sensors and are composed of a light emitting element 6A and a light receiving element 6B.

상기 포토커플러(6A,6B)는 드럼(5)이 회전하면서 상기 홈(1,2,3,4)을 통과할 때 신호를 입력받도록 구성된다.The photocouplers 6A, 6B are configured to receive signals as the drum 5 rotates and passes through the grooves 1, 2, 3, 4.

상기 포토커플러(6A,6B)의 사이와 드럼(5)의 외주면에는 사출 성형된 돌출부(7)가 원주방향으로 형성된다.Injection molded protrusions 7 are formed in the circumferential direction between the photocouplers 6A and 6B and on the outer circumferential surface of the drum 5.

상기 돌출부(7)는 상기 드럼(5) 회전시 함께 회전하도록 구성된다.The protrusion 7 is configured to rotate together when the drum 5 rotates.

상기 돌출부(7)는 포토커플러(6A,6B)의 홈(1,2,3,4)이 형성된 부분에서는 수신을 보내다가 홈(1,2,3,4)이 형성되지 않은 나머지 공간에서는 수신을 차단하도록 구성된다.
The protruding portion 7 receives a reception in a portion where the grooves 1, 2, 3, and 4 of the photocouplers 6A and 6B are formed, and receives the rest of the space where the grooves 1, 2, 3, and 4 are not formed. It is configured to block.

본 발명의 구성에 따른 회전방향 감지방법은 다음과 같다.The rotation direction detection method according to the configuration of the present invention is as follows.

먼저 제품의 초기 단계에서 모터를 작동하게 하여 긴 간격을 가진 홈과 짧은 간격을 가진 홈을 통과하도록 한다.First, start the motor in the early stages of the product, passing through the long gap and the short gap.

도 3은 포토커플러가 ON, OFF되는 것을 도시한 것으로 ON된 신호의 사이는 신호 간격을 의미한다.3 shows that the photocoupler is turned on and off, and means a signal interval between the signals turned on.

도 3에 도시된 바와 같이, 모터의 작동으로 드럼(5)이 회전시, 초기 위치에서 먼저 들어오는 신호간격이 짧을 경우(I) 즉, 제1홈(1) 및 제2홈(2)을 지나갈 때 포토커플러(6A,6B)는 빛을 주고 받으면서 드럼(5)이 정방향으로 회전하고 있다는 것을 감지한다.As shown in FIG. 3, when the drum 5 rotates due to the operation of the motor, when the signal interval that comes first from the initial position is short (I), that is, the first groove 1 and the second groove 2 will pass. When the photocoupler 6A, 6B transmits and receives light, it senses that the drum 5 is rotating in the forward direction.

또한, 제1홈(1)을 지나고 제3홈(3)을 지날 때 포토커플러는(6A,6B)는 빛을 주고 받으면서 드럼(5)이 역방향으로 회전하는 것을 감지한다.In addition, when passing through the first groove 1 and the third groove 3, the photocoupler 6A, 6B senses that the drum 5 rotates in the reverse direction while transmitting and receiving light.

즉, 초기 포인트에서 정방향 운전하였을 때 짧은 간격을 가진 홈을 지나가고, 역방향 운전하였을 때 긴 간격을 가진 홈을 지나가도록 디스크를 설계하고, 이러한 방법으로 드럼 디스크의 회전방향을 입력받도록 구성된다.That is, the disk is designed to pass the groove with a short interval when driving forward at the initial point, and the groove with a long interval when driving backward, and is configured to receive the rotation direction of the drum disk in this way.

또한, 일정 시간 내에 상기 홈(1,2,3,4)에서의 신호를 3번 이상 입력받지 못한 경우에 드럼의 회전을 정지하고, 에러 메세지를 출력하도록 구성된다.
In addition, when the signal from the grooves (1, 2, 3, 4) is not received more than three times within a predetermined time, the rotation of the drum is stopped and an error message is output.
