도 3은 본 발명에 따른 드럼 세탁기의 콘트롤러 보호장치를 나타낸 블록도이다.Figure 3 is a block diagram showing a controller protection device of the drum washing machine according to the present invention.

여기서, 본 발명에 따른 드럼 세탁기의 구성은 상술한 종래의 그 구성과 동일하나, 도시한 바와 같이, 본 발명에 따른 드럼 세탁기의 콘트롤러 보호장치로서, 콘트롤러(10)의 주위 온도를 감지하기 위한 온도 감지부(10)가 콘트롤러(11) 내부 또는 상기 콘트롤러(11)의 인접한 소정 위치에 구성됨이 상이하다.Here, the configuration of the drum washing machine according to the present invention is the same as the conventional configuration described above, as shown, as a controller protection device of the drum washing machine according to the present invention, the temperature for sensing the ambient temperature of the controller 10 The sensing unit 10 is different from the inside of the controller 11 or a predetermined position adjacent to the controller 11.

이때, 상기 온도 감지부(10)는 써미스터(Thermistor)가 이용되며, 상기 써미스터(Th)는 주위 온도변화에 따라 내부 저항 값이 변화한다. 상기 변화된 내부 저항 값과 상기 써미스터(Th)에 연결된 저항(R) 값과의 분배에 따른 전압값을 출력하여 상기 온도 감지부(10)를 통해 출력된 전압값이 상기 콘트롤러(11)로 입력된다.In this case, the temperature sensing unit 10 uses a thermistor, and the thermistor Th changes its internal resistance according to the change in ambient temperature. The voltage value output through the temperature sensing unit 10 is output to the controller 11 by outputting a voltage value according to a distribution between the changed internal resistance value and the resistance R value connected to the thermistor Th. .

그리고, 상기 콘트롤러(11)는 상기 온도 감지부(10)로부터 입력된 전압값으로부터 상기 콘트롤러(11) 주위 온도를 판단한다.The controller 11 determines the ambient temperature of the controller 11 from the voltage value input from the temperature sensor 10.

상기와 같이 구성된 본 발명에 따른 드럼 세탁기의 콘트롤러 보호장치를 설명하면 다음과 같다.Referring to the controller protection device of the drum washing machine according to the present invention configured as described above are as follows.

먼저, 세탁포를 투입하고 사용자로부터 입력된 세탁관련행정을 수행할 수 있도록 상기 드럼(2) 내에 세탁수를 설정수위까지 투입한다. 세탁수가 설정수위 이상으로 채워지면 모터가 구동하고 상기 드럼(2)이 회전하여 세탁관련행정이 진행된다.First, the washing water is put into the drum 2 and the washing water is input to the set water level so as to perform the washing-related administration input from the user. When the washing water is filled above the set water level, the motor is driven and the drum 2 rotates to perform washing related administration.

이때, 사용자가 입력한 세탁관련행정 중 삶음 행정 수행시 상기 콘트롤러(11)는 상기 히터 구동부(12)를 제어하여 상기 히터(13)를 구동시키고 상기 드럼(2)에 투입된 세탁수를 기 설정된 온도까지 가열한다.At this time, the controller 11 controls the heater driving unit 12 to drive the heater 13 when the boil-off stroke is performed during the washing-related administration input by the user, and the preset temperature of the washing water injected into the drum 2 is set. Heat to

이어서, 상기 설정 온도까지 상기 세탁수가 가열되면 기 설정된 시간동안 상기 삶음 행정을 수행한다.Subsequently, when the wash water is heated up to the preset temperature, the boil stroke is performed for a preset time.

상기 삶음 행정 수행 중, 상기 온도 감지부(10)를 통해 상기 콘트롤러(11)의 주위 온도를 감지하고 상기 감지된 콘트롤러(11)의 주위 온도가 상기 콘트롤러(11)에 기 저장된 설정온도 이상이 되면 상기 히터 구동부(12)에 제어신호를 출력하여 상기 히터(13)의 구동을 중단한다.During the boil-off stroke, when the ambient temperature of the controller 11 is sensed through the temperature sensing unit 10 and the detected ambient temperature of the controller 11 becomes higher than or equal to a preset temperature stored in the controller 11. The control signal is output to the heater driver 12 to stop driving of the heater 13.

따라서, 본 발명에서 상기 콘트롤러(11)의 내부 또는 인접한 위치에 상기 온도 감지부(10)를 장착하여 삶음 행정시 상기 온도 감지부(10)를 통해 상기 콘트롤러(11)의 주위 온도를 감지하고 감지된 주위온도가 설정온도 이상으로 상승하게 되면 상기 히터(13)의 구동을 중단함으로서 상기 콘트롤러(11)의 주위 온도 상승을 억제한다.Therefore, in the present invention, the temperature sensing unit 10 is mounted inside or adjacent to the controller 11 to sense and sense the ambient temperature of the controller 11 through the temperature sensing unit 10 during the boiling stroke. When the ambient temperature rises above the set temperature, the driving of the heater 13 is stopped to suppress the increase in the ambient temperature of the controller 11.

이상에서 설명한 본 발명에 따른 드럼 세탁기의 콘트롤러 보호장치는 드럼 세탁기 콘트롤러의 주위 온도가 설정 온도 이상으로 상승하게 되면 히터의 구동을 중단함으로서 콘트롤러의 비정상적인 온도 상승으로 인한 회로 부품 손상을 방지하여 제품 신뢰성을 향상시킬 수 있는 효과가 있다.The controller protection device of the drum washing machine according to the present invention described above stops the operation of the heater when the ambient temperature of the drum washing machine controller rises above the set temperature, thereby preventing damage to circuit components due to abnormal temperature rise of the controller, thereby improving product reliability. There is an effect that can be improved.

이상에서 설명한 내용을 통해 당업자라면 본 발명의 기술 사상을 이탈하지 아니하는 범위에서 다양한 변경 및 수정이 가능함을 알 수 있을 것이다.Those skilled in the art will appreciate that various changes and modifications can be made without departing from the spirit of the present invention.

따라서, 본 발명의 기술적 범위는 실시예에 기재된 내용으로 한정되는 것이 아니라 특허청구범위에 의하여 정해져야 한다.Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
