In this case, although not shown, the drum washing machine including the steam generator of the present invention controls the heater 55. A 200 is provided and the pressure sensor 100 and the heater 55 are electrically connected to the microcomputer 200.

상기와 같이 구성된 본 발명에 따른 실시예의 작용을 설명하면 다음과 같다.Referring to the operation of the embodiment according to the present invention configured as described above are as follows.

도 5를 참조하면, 상기 급수호스(25:도 1 참조)를 통하여 상기 증기발생장치(50) 내부로 세탁수가 유입되고, 히터(55)가 가동하여 세탁수가 가열된다.Referring to FIG. 5, the washing water flows into the steam generator 50 through the water supply hose 25 (see FIG. 1), and the washing machine 55 is operated to heat the washing water.

그리고, 가열된 수증기가 상기 증기공급관(53:도 1 참조)을 통하여 상기 드럼(30) 내부로 유입되면서 세탁과정이 진행된다.Then, the heated water vapor flows into the drum 30 through the steam supply pipe 53 (see FIG. 1), and the washing process is performed.

그리고, 상기 수위센서(60)는 상기 증기발생장치(50) 내부에 저장된 물에 상기 수위센서(60)에 구비된 각각의 전극부(62,63,64:도 3 참조)가 물에 잠기면서 전류가 흐르게 되면 수위를 감지하게 된다.In addition, the water level sensor 60 is submerged in the water of each electrode unit 62, 63, 64 provided in the water level sensor 60 in the water stored in the steam generator (50) When the current flows, the water level is sensed.

한편, 상기 증기공급관(53)과 연결되는 증기발생장치(50)의 공급관(52b)에 이물질이 끼어 막히게 되면, 공급되는 물에 의하여 또는 히터(55)에 의하여 공급된 물이 계속 끓는 상태를 유지하게 되고, 상기 증기발생장치(50) 내부에는 과도한 압력이 걸리게 되는데, 상기 증기발생장치(50)에 부착된 압력센서(100)가 증기발생장 치(50) 내부의 압력을 측정하고, 측정된 압력을 상기 마이컴(200)에 전기적 신호를 통하여 보내게 된다.On the other hand, when foreign matter is blocked in the supply pipe 52b of the steam generator 50 connected to the steam supply pipe 53, the water supplied by the supplied water or by the heater 55 is kept boiling. When the excessive pressure is applied to the steam generator 50, the pressure sensor 100 attached to the steam generator 50 measures the pressure inside the steam generator 50 and is measured. The pressure is sent to the microcomputer 200 through an electrical signal.

이렇게 되면, 상기 마이컴(200)은 측정된 압력과 기 설정된 압력을 비교하여, 기 설정된 압력보다 측정된 압력이 높은 경우에, 전기적으로 연결되어 있는 히터(55)를 제어하여, 상기 가동하는 히터(55)를 정지시킨다.In this case, the microcomputer 200 compares the measured pressure with the preset pressure, and when the measured pressure is higher than the preset pressure, the microcomputer 200 controls the heater 55 that is electrically connected to the movable heater ( Stop 55).

이렇게 되면, 상기 증기발생장치 내부에 공급된 물의 온도를 낮출 수 있게 되어, 물이 끓는 것을 방지할 수 있게 되며, 상기 증기발생장치 내부에 과도한 압력이 발생하는 것을 방지할 수 있게 된다.In this case, it is possible to lower the temperature of the water supplied to the steam generator, it is possible to prevent the water from boiling, it is possible to prevent the excessive pressure generated in the steam generator.

본 발명은 상술한 실시예에 한정되지 않으며, 첨부된 청구범위에서 알 수 있는 바와 같이 본 발명이 속한 분야의 통상의 지식을 가진 자에 의해 변형이 가능하고 이러한 변형은 본 발명의 범위에 속한다.The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.

상기와 같이 구성된 본 발명 드럼세탁기의 효과에 대하여 설명하면 다음과 같다.Referring to the effects of the drum washing machine of the present invention configured as described above are as follows.

증기발생장치의 공급관이 막히는 경우 등에 히터의 작동으로 인하여 내부에 공급된 물이 끓어 증기발생장치 내 압력이 증가하는 경우에 압력센서가 이를 감지하여 히터의 작동을 종료하도록 하여, 증기발생장치 내 과도한 압력이 걸리는 것을 방지할 수 있게 해주는 효과가 있다.When the water supply to the inside of the steam generator increases due to the operation of the heater, such as when the supply pipe of the steam generator is clogged, the pressure sensor detects this and terminates the operation of the heater. It has the effect of preventing pressure from being applied.
