세탁물 처리기기의 작동 시, 온도측정장치는 유입되는 세탁수와 접촉하여 세탁수의 온도를 측정한다. 온도측정장치가 외부의 충격 등으로 인한 파손으로 인하여 세탁수와 접촉하게 되면, 터브와 세탁수를 통하여 전기가 흐르게 된다. 전기가 흐르는 것을 감지하지 못하고 사용자가 터브나 세탁수에 접촉하면, 감전되어 치명적인 사고가 발생할 수 있다. During operation of the laundry treatment machine, the temperature measuring device contacts the incoming washing water and measures the temperature of the washing water. When the temperature measuring device comes into contact with the wash water due to damage due to an external impact, the electricity flows through the tub and the wash water. If the user does not detect the flow of electricity and the user comes in contact with the tub or wash water, an electric shock may result in a fatal accident.

본 발명은, 온도측정장치의 단락 시, 전원을 차단하여 감전사고로부터 사용자를 보호하는 것에 목적이 있다.An object of the present invention is to protect the user from electric shock by cutting off the power supply when the temperature measuring device is short-circuited.

본 발명은, 터브에 배치되며 상기 터브내의 세탁수의 온도를 측정하는 온도측정장치와, 상기 온도측정장치가 단락 시, 제어신호에 의하여 상기 온도측정장치의 전원을 차단하는 제어부를 포함하는 세탁물 처리기기를 제공한다.The present invention includes a temperature measuring device disposed on the tub and measuring the temperature of the washing water in the tub, and the laundry treatment process includes a control unit for shutting off the power of the temperature measuring device by a control signal when the temperature measuring device is short-circuited. Provide the appliance.

The output unit 118 may include a display device that displays the driving information as an image to a user, and may include a voice output unit which displays the driving information as a voice to the user. The output unit 118 includes not only the display device or the audio output unit but also a means for displaying the driving information by a user from outside.

도 2를 참조하면, 세탁물 처리기기(100)는 터브(미도시)에 배치되어 상기 터브내 세탁수의 온도를 측정하는 온도측정장치(180)를 포함한다. 온도측정장치(180)는 상기 터브 내의 세탁수의 온도를 측정하여 상기 세탁수온도를 제어부(160)로 전송한다. 상기 전송된 세탁수온도를 바탕으로 세탁물 처리기기(100)는 운전모드 및 세제량 등을 조절한다. 온도측정장치(180)는 제어부(160)에서 전송되는 전기신호에 의하여 작동한다. 상기 전기신호는 릴레이(170)를 통하여 전송되고, 릴레이(170)는 제어부(160)에서 전송되는 제어신호에 따라 온도측정장치(180)로 상기 전기신호를 전송하거나 전송하지 않는다. 단락감지부(190)는 온도측정장치(180)의 단락여부를 감지한다. 단락감지부(190)는 온도측정장치(180)가 단락되면, 제어부(160)로 신호를 전송한다. 제어부(160)는 상기 전송된 신호를 근거로 온도측정장치(180)의 단락여부를 판단하고 릴레이(170)로 상기 제어신호를 전송한다. 릴레이(170)가 작동하여 온도측정장치(180)의 전원을 차단하면, 제어부(160)는 출력부(118)로 경고알람신호를 전송한다. 상기 전송된 경고알람신호는 출력부(118)를 통하여 사용자가 인식할 수 있도록 외부로 표출된다. 출력부(118)는 사용자가 외부에서 인식할 수 있는 모든 기기들을 포함할 수 있다. 출력부(118)는 사용자가 화상으로 인식할 수 있는 디스플레이장치 또는 음성으로 인식할 수 있는 음성출력부를 포함할 수 있다. 상기의 제어흐름의 순서를 살펴보면, 하기와 같다.Referring to FIG. 2, the laundry treatment apparatus 100 includes a temperature measuring device 180 disposed in a tub (not shown) to measure a temperature of the washing water in the tub. The temperature measuring device 180 measures the temperature of the wash water in the tub and transmits the wash water temperature to the controller 160. The laundry treatment device 100 adjusts an operation mode and a detergent amount based on the transmitted wash water temperature. The temperature measuring device 180 operates by an electric signal transmitted from the controller 160. The electrical signal is transmitted through the relay 170, the relay 170 does not transmit or transmit the electrical signal to the temperature measuring device 180 according to the control signal transmitted from the controller 160. The short circuit detection unit 190 detects whether the temperature measuring device 180 is short. The short circuit detection unit 190 transmits a signal to the control unit 160 when the temperature measuring device 180 is shorted. The controller 160 determines whether the temperature measuring device 180 is short based on the transmitted signal, and transmits the control signal to the relay 170. When the relay 170 operates to cut off the power of the temperature measuring device 180, the controller 160 transmits a warning alarm signal to the output unit 118. The transmitted alarm signal is output to the user through the output unit 118 to recognize. The output unit 118 may include all devices that can be externally recognized by the user. The output unit 118 may include a display device that a user can recognize as an image or a voice output unit that can be recognized as a voice. Looking at the order of the control flow, it is as follows.

도 3은 도 1에 도시된 세탁물 처리기기(100)의 작동 순서를 보여주는 순서도이다.3 is a flow chart showing an operation sequence of the laundry treatment machine 100 shown in FIG.

도 3을 참조하면, 온도측정장치(180)의 작동이 시작되면,(S110단계) 온도측정장치(180)의 전원이 인가된다. 상기 전원의 인가는 릴레이(170)를 통하여 이루어지고, 제어부(160)는 릴레이(170)에 상기 제어신호를 전송하여 전원을 유지하도록 한다.(S120단계) 온도측정장치(180)에 전원이 인가되면, 단락감지부(190)는 온도측정장치(180)의 단락여부를 감지한다. 제어부(160)는 단락감지부(190)에서 감지된 단락여부를 전송받아 온도측정장치(180)의 단락여부를 판단한다.(S130단계) 온도측정장치(180)가 단락되지 않은 것으로 판단되면, 상기 S130단계부터 실행되어 온도측정장치(180)가 단락되었는지 다시 판단한다. Referring to Figure 3, when the operation of the temperature measuring device 180 is started (step S110), the power of the temperature measuring device 180 is applied. The power is applied through the relay 170, and the controller 160 transmits the control signal to the relay 170 to maintain the power. (S120) Power is applied to the temperature measuring device 180. If so, the short circuit detection unit 190 detects whether the temperature measuring device 180 is short. The control unit 160 receives whether the short circuit detected by the short circuit detection unit 190 determines whether or not the short circuit of the temperature measuring device 180. (S130) If it is determined that the temperature measuring device 180 is not short-circuited, It is determined from the step S130 to determine again whether the temperature measuring device 180 is short-circuited.

한편, 온도측정장치(180)가 단락된 것으로 판단되면, 제어부(160)는 릴레이(170)로 제어신호를 전달한다. 상기 제어신호는 제어부(160)가 전송할 수도 있고, 사용자에 의하여 수동신호가 인가되면 제어부(160)가 릴레이(170)을 작동시킬 수도 있다. 상기 제어신호가 전달되면, 릴레이(170)가 작동하여 온도측정장치(180)의 전원을 차단한다.(S140단계) 상기 전원이 차단되면, 사용자가 온도측정장치(180)이 단락되었음을 인식할 수 있도록 출력부(118)를 통하여 경고알람을 출력한다.(S150단계) On the other hand, if it is determined that the temperature measuring device 180 is short-circuited, the controller 160 transmits a control signal to the relay 170. The control signal may be transmitted by the controller 160, or when the manual signal is applied by the user, the controller 160 may operate the relay 170. When the control signal is transmitted, the relay 170 operates to cut off the power of the temperature measuring device 180. (S140) When the power is cut off, the user can recognize that the temperature measuring device 180 is short-circuited. Outputs a warning alarm through the output unit 118 so as to (S150).

따라서 사용자는 온도측정장치(180)가 단락 시, 단락여부를 인식할 수 있다. 그러므로 온도측정장치(180)의 단락으로 인한 감전사고 등을 방지할 수 있다. 또한, 온도측정장치(180)가 단락되면, 온도측정장치(180)의 전원을 자동으로 차단할 수 있다. 사용자는 상기 제어신호에 의하여 온도측정장치(180)의 전원이 차단되므로 외부에서 인식하지 못하더라도 감전사고 등을 방지할 수 있다. Therefore, the user may recognize whether the temperature measuring device 180 has a short circuit. Therefore, an electric shock accident due to a short circuit of the temperature measuring device 180 can be prevented. In addition, when the temperature measuring device 180 is short-circuited, the power of the temperature measuring device 180 may be automatically cut off. The user can prevent the electric shock accident, even if not recognized from the outside because the power of the temperature measuring device 180 is cut by the control signal.
