Description

통신 케이블{Communication Cable}Communication Cable {Communication Cable}

본 발명은 통신 케이블 및 포트에 관한 것으로서, 더욱 상세하게는 세탁기(washer)와 건조기(dryer)가 분리된 세탁 장치에서 상기 세탁기와 건조기 간의 정보 전달을 위한 통신 케이블에 관한 것이다.The present invention relates to a communication cable and a port, and more particularly, to a communication cable for transferring information between the washing machine and the dryer in a washing apparatus in which a washing machine and a dryer are separated.

일반적으로, 드럼 세탁 방식은 세제와 세탁수 및 세탁물이 드럼 내에 투입된 상태에서, 모터의 구동력을 전달받아 회전하는 드럼과 세탁물의 마찰력을 이용하여 세탁을 행하는 방식으로서, 세탁물의 손상이 거의 없고, 세탁물이 서로 엉키지 않으며, 두드리고 비벼 빠는 세탁효과를 낼 수 있다. 또한, 세탁 기능 뿐만아니라 세탁된 세탁물을 건조시키는 기능까지도 갖고 있다.In general, the drum washing method is a method of washing the laundry using the friction force of the rotating drum and the laundry by receiving the driving force of the motor in a state in which detergent, washing water and laundry are put in the drum, there is almost no damage to the laundry, laundry These don't get tangled with each other and can have a pounding and scrubbing wash effect. In addition to the washing function, it also has a function of drying the laundry.

이와 같이 세탁 기능 및 건조 기능을 갖는 세탁기의 경우는 별도의 통신케이블이 필요 없지만, 세탁 기능만을 갖는 세탁기와 건조 기능을 갖는 건조기가 별도로 설치될 경우에는 상기 세탁기와 건조기간의 정보(포량, 온도, 습도)를 전달하기 위한 통신 케이블이 필요하게 된다.As such, a washing machine having a washing function and a drying function does not require a separate communication cable. However, when a washing machine having a washing function and a dryer having a drying function are separately installed, the information (amount, temperature, Communication cables are needed.

이와 같이 세탁기와 건조기간의 정보를 전달하기 위한 통신 케이블이 별도로 구비되는 것이 아니라, PC와 주변기기간의 정보 전달을 위해 사용되는 RS-232C 통신 케이블이 범용으로 사용되고 있다.As such, a communication cable for transferring information between the washing machine and the dryer is not provided separately, but an RS-232C communication cable used for transferring information between a PC and a peripheral device is used for general purposes.

상기와 같은 종래의 RS-232C 통신케이블 및 콘넥터의 구성을 첨부된 도면을 참조하여 설명하면 다음과 같다.The configuration of the conventional RS-232C communication cable and connector as described above with reference to the accompanying drawings as follows.

도 1은 종래의 통신 케이블의 콘넥터들의 구성도이다.1 is a block diagram of connectors of a conventional communication cable.

PC와 주변 기기 간의 정보 전달을 위해 사용되는 직렬 통신 케이블은, 도 1에 도시한 바와 같이, RS-232C (도 1의 a), RS-422 (도 1의 b) 및 RS-485 (도 1의 c) 등이 있다. 이들 모두의 통신 케이블은 모두 9개의 핀으로 구성되어 있으며, 이와 같은 9개의 핀 중에 PC에서는 2, 3, 8번 핀(RXD, TXD, CTS)으로는 보통 DC 10V∼15V의 전압을 전송하고 있다.The serial communication cable used for transferring information between the PC and the peripheral device is, as shown in FIG. 1, RS-232C (FIG. 1A), RS-422 (FIG. 1B), and RS-485 (FIG. 1). C) and the like. All of these communication cables consist of nine pins, and among these nine pins, PCs transmit voltages of DC 10V to 15V with pins 2, 3 and 8 (RXD, TXD, CTS). .

또한, 통신 케이블은 상기 핀의 수에 상응하는 통신 라인 양측 또는 일측에 각각 콘넥터(female connector 또는 male connector)가 연결되어 있다. 예를 들면, PC와 모니터는 상기 PC에 암 콘넥터(female connector)가 설치되고 모니터에 연결된 통신 케이블의 끝단에는 숫 콘넥터(male connector)가 설치되어 상기 두 콘넥터를 서로 연결할 수 있도록 되어 있다.In addition, a communication cable has a connector (female connector or male connector) connected to each side or one side of the communication line corresponding to the number of the pins. For example, the PC and the monitor are provided with a female connector on the PC and a male connector at the end of the communication cable connected to the monitor to connect the two connectors to each other.

그러나, 상기와 같이 PC에서 사용하고 있는 통신 케이블을 세탁기와 건조기 간의 정보 전달을 위한 케이블로 이용하고 있기 때문에 사용자가 세탁기 또는 건조기의 통신포트와 PC의 통신 포트를 상기 통신 케이블(RS-232C)로 연결할 경우, 상기 PC에서 2, 3, 8번 핀을 통해 출력되는 전압에 의해 세탁기 또는 건조기의 콘트롤러가 오동작을 하거나 부품이 손상될 가능성이 매우 높다.However, since the communication cable used in the PC is used as a cable for transmitting information between the washing machine and the dryer, the user uses the communication port of the washing machine or the dryer and the communication port of the PC as the communication cable (RS-232C). When connected, there is a high possibility that the controller of the washing machine or the dryer may malfunction or the parts may be damaged by the voltage output through pins 2, 3, and 8 from the PC.

본 발명은 이와 같은 문제점을 해결하기 위하여 안출한 것으로, 상기 10∼15V의 전압이 통전되고 있는 2, 3, 8번 핀은 사용되지 않도록 한 통신 케이블 및 통신 포트를 제공하는데 그 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a communication cable and a communication port in which pins 2, 3, and 8 through which the voltage of 10 to 15V is energized are not used.
