And a blowing pulley 72 connected to the impeller 70 and the rotating shaft of the impeller 70 installed at one side of the circulation pipe 60, and detachable between the blowing pulley 72 and the drum pulley 49. The connection pulley 90 is installed so that the rotational force of the drum pulley 49 is transmitted to the blowing pulley 72, and the connection Lee (90) are provided to enable the flow consists includes the adjusting means (92) provided in the tub (42).

이로써, 모터(46)에 전원이 인가되면 모터풀리(47)가 회전되고, 벨트(48)의 구동에 의해 드럼풀리(49)가 회전되므로 드럼(44) 내부에 담겨진 세탁물에 세탁작동이 이루어진다.As a result, when power is applied to the motor 46, the motor pulley 47 is rotated, and the drum pulley 49 is rotated by the driving of the belt 48. Thus, the washing operation is performed on the laundry contained in the drum 44.

세탁작동이 종료된 후에는 세탁물을 말리는 건조작업이 진행되는 바, 상기 모터(46)가 구동되어 모터풀리(47)가 구동되면 벨트(48)에 의해 연결된 드럼풀리(49) 및 드럼(44)이 회전되고, 상기 연결풀리(90)가 가변수단(92)에 의해 드럼풀리 (49)와 송풍풀리(72) 사이에 개재되면 풀리 사이의 마찰력에 의해 드럼풀리(49) 및 연결풀리(90), 송풍풀리(72)가 모두 회전된다.After the washing operation is finished, the drying operation of drying the laundry is performed. When the motor 46 is driven and the motor pulley 47 is driven, the drum pulley 49 and the drum 44 connected by the belt 48 are driven. When the connection pulley 90 is interposed between the drum pulley 49 and the blowing pulley 72 by the variable means 92, the drum pulley 49 and the connection pulley 90 are driven by the friction force between the pulleys. , The blowing pulley 72 is all rotated.

이로써, 송풍풀리(72)의 회전축에 연결된 임펠러(70)가 회전되면서 터브(42) 및 드럼(44) 내부의 공기가 순환관(60)을 따라 순환될 수 있도록 한다.As a result, the impeller 70 connected to the rotary shaft of the blower pulley 72 is rotated so that the air in the tub 42 and the drum 44 can be circulated along the circulation pipe 60.

이때, 상기 히터(80)에는 전원이 인가되어 고온이 발생되므로 히터(80)를 지나는 공기가 가열되어 터브(42) 및 드럼(44) 내부에 습기가 쉽게 제거될 수 있도록 한다.In this case, since power is applied to the heater 80 to generate a high temperature, the air passing through the heater 80 is heated so that moisture can be easily removed from the tub 42 and the drum 44.

도 5는 본 발명에 의한 드럼세탁기의 건조장치의 히터가 도시된 사시도이다.5 is a perspective view showing a heater of the drying apparatus of the drum washing machine according to the present invention.

상기 히터(80)는 전원이 인가되어 열을 발하는 코일(82)과, 상기 코일(82)이 고정되어 터브(42) 내벽에 설치되는 브래킷(84)과, 상기 브래킷(84) 일 측에 설치된 온도센서(86)와, 상기 온도센서(86)와 코일(82) 사이에 설치되고, 일정치 이상의 전도율을 가지는 고전도성 재질로 이루어진 전도패널(88)이 포함되어 구성된다.The heater 80 is provided with a coil 82 that generates heat by applying power, a bracket 84 fixed to the coil 82 and installed on an inner wall of the tub 42, and installed on one side of the bracket 84. The temperature sensor 86, and the conductive panel 88 is provided between the temperature sensor 86 and the coil 82, and made of a highly conductive material having a conductivity of a predetermined value or more.

이로써, 코일(82)에서 발생되는 열 에너지는 전도패널(88)을 따라 온도센서(86)에 전달되므로 코일(82)의 현재 온도를 온도센서(86)에서 쉽게 감지할 수 있도록 함으로써, 코일(82)이 세탁수에 잠기지 않아도 코일(82)의 온도를 온도센서(86)에서 쉽게 감지할 수 있으므로 온도센서(86)의 오작동에 의해 코일(82)이 필요 이상으로 과열되는 것을 방지할 수 있도록 한다.Thus, the heat energy generated in the coil 82 is transmitted to the temperature sensor 86 along the conducting panel 88, so that the current temperature of the coil 82 can be easily detected by the temperature sensor 86, thereby providing a coil ( Since the temperature of the coil 82 can be easily detected by the temperature sensor 86 even when the 82 is not immersed in the wash water, it is possible to prevent the coil 82 from being overheated more than necessary by the malfunction of the temperature sensor 86. do.

아울러, 상기 가변수단(92)은 상기 터브(42) 배면에 설치된 실린더로서, 실린더의 암이 돌출되면 암의 단부에 설치된 연결풀리(90)가 드럼풀리(49)와 송풍풀리(72) 사이에 개재되어 서로 연동되도록 한다.In addition, the variable means 92 is a cylinder provided on the back of the tub 42, and when the arm of the cylinder protrudes, a connection pulley 90 installed at the end of the arm is provided between the drum pulley 49 and the blow pulley 72. Intervene to interlock with each other

이로써, 별도의 모터 없이 임펠러(70)를 회전시켜 히터(80)에 의해 가열된 공기가 터브 및 드럼 내부를 순환할 수 있도록 한다.As a result, the impeller 70 is rotated without a separate motor so that the air heated by the heater 80 can circulate inside the tub and the drum.

상기와 같이 구성된 본 발명에 의한 드럼세탁기의 건조장치의 동작을 살펴보면 다음과 같다.Looking at the operation of the drying apparatus of the drum washing machine according to the present invention configured as described above are as follows.

먼저, 전원이 인가되어 모터(46)가 구동되면 모터풀리(47)에 벨트(48)로 연결된 드럼풀리(49)가 회전되면서 드럼(44)이 회전되어 드럼 내부에 담겨진 세탁물에 세탁작동이 이루어진다.First, when power is applied and the motor 46 is driven, the drum pulley 49 connected to the motor pulley 47 by the belt 48 is rotated and the drum 44 is rotated to wash the laundry contained in the drum. .

이후에 세탁작동이 종료되면 실린더의 암이 돌출되어 연결풀리(90)가 드럼풀리(49)와 송풍풀리(72) 사이에 개재되면서 3개의 풀리가 모두 연동된다. 이렇게 송풍풀리(72)가 회전되면 송풍풀리(72)의 회전축에 설치된 임펠러(70)가 구동되므로 히터(80)에 의해 가열된 고온의 공기가 드럼(44) 및 터브(42)의 내부로 순환되어 건조작업을 행한다.After the washing operation is finished, the arm of the cylinder protrudes so that the connection pulley 90 is interposed between the drum pulley 49 and the blowing pulley 72 and all three pulleys are interlocked. When the blowing pulley 72 is rotated in this way, the impeller 70 installed on the rotating shaft of the blowing pulley 72 is driven, so that hot air heated by the heater 80 circulates inside the drum 44 and the tub 42. And drying operation is performed.

이때, 상기 히터(80)는 전도패널(88)에 의해 코일(82)의 온도가 온도센서(84)에 직접 전달되므로 코일의 정확한 온도를 알 수 있어 최적의 온도제어를 할 수 있다.In this case, since the temperature of the coil 82 is directly transmitted to the temperature sensor 84 by the conductive panel 88, the heater 80 may know the exact temperature of the coil, thereby enabling optimal temperature control.

상기와 같이 구성되는 본 발명에 의한 드럼세탁기의 건조장치는 별도의 구동장치 없이 드럼의 회전력을 임펠러의 회전으로 변환시킴으로써, 건조작업에 소요되는 비용을 절감할 수 있는 이점이 있다.The drying apparatus of the drum washing machine according to the present invention configured as described above has an advantage of reducing the cost of the drying operation by converting the rotational force of the drum into the rotation of the impeller without a separate driving device.

또한, 히터에 고전도성 재질의 전도패널이 설치됨으로써, 코일의 온도를 온도센서에서 정확하게 감지할 수 있도록 하므로 건조작업 중에 히터가 필요 이상으로 가열되는 것을 방지하여 안전사고를 예방할 수 있는 이점이 있다.In addition, since a conductive panel made of a highly conductive material is installed in the heater, the temperature of the coil can be accurately detected by the temperature sensor, thereby preventing the heater from being heated more than necessary during the drying operation, thereby preventing a safety accident.
