Field of the Invention The present invention relates to a drum type washing machine, and more particularly, to a drum type washing machine having a light transmitting member mounted with a plurality of LEDs for displaying an operation of a dial knob so that a user can recognize the operation.

일반적으로, 드럼세탁기는 세탁물을 상측으로 끌어올린 후 낙하시키며 그 낙차에 의해 세탁이 이루어지게 하는 장치이며, 이러한 드럼세탁기에는 외관을 형성하는 본체와, 이 본체의 내부에 설치되어 세탁수를 담는 터브와, 이 터브 내부에 회전 가능하게 설치되는 회전드럼이 마련된다. 2. Description of the Related Art Generally, a drum type washing machine is a device for pulling laundry upwards and then dropping the laundry, and washing the laundry by the falling of the laundry. The drum type washing machine includes a main body that forms an outer appearance, And a rotary drum rotatably installed in the tub.

이러한 드럼세탁기는 수평으로 배치된 회전드럼이 시계방향과 반시계방향으로 교번적으로 회전함에 따라 회전드럼의 내주면을 따라 세탁물을 세탁수와 함께 상하 방향으로 운동시킴으로써 세탁물을 세탁 및 탈수하게 된다.The drum washing machine alternately rotates clockwise and counterclockwise rotating drums horizontally to move the laundry along the inner circumferential surface of the drum in the vertical direction together with the washing water, thereby washing and dehydrating the laundry.

한편, 상기와 같은 드럼세탁기에는 본체의 전방측 상부에 사용자가 드럼세탁기의 기능을 선택하여 조절할 수 있도록 다이얼노브가 설치되는 컨트롤패널이 마련된다. Meanwhile, in the drum type washing machine as described above, a control panel is provided on the front side of the main body, on which a dial knob is installed so that a user can select and control the function of the drum type washing machine.

컨트롤패널의 내부에는 다이얼노브를 통해 입력된 동작을 수행하도록 드럼세탁기의 내부기기들을 제어하는 회로기판이 마련된다. 그리고, 회로기판에는 사용자에 의한 다이얼노브의 조작을 회로기판으로 전달하는 엔코더와, 사용자에 의한 다이얼노브의 조작에 따른 드럼세탁기의 작동의 표시를 위한 다수의 LED가 장착된다.Inside the control panel, a circuit board for controlling internal devices of the drum washing machine is provided so as to perform an operation input through a dial knob. The circuit board is provided with an encoder for transmitting the operation of the dial knob by the user to the circuit board and a plurality of LEDs for displaying the operation of the drum washing machine according to the operation of the dial knob by the user.

컨트롤패널과 회로기판의 사이에는 다이얼노브가 회전 가능하게 장착되며, 엔코더가 다이얼노브에 장착될 수 있도록 관통되는 관통공이 형성된 엔코더 브라켓 이 마련된다. 또, 엔코더 브라켓에는 회로기판에 장착된 다수의 LED를 보호하기 위한 보호리브가 형성되어 있다.Between the control panel and the circuit board, a dial knob is rotatably mounted, and an encoder bracket having a through-hole formed therein for mounting the encoder on the dial knob is provided. The encoder bracket is provided with a protection rib for protecting a plurality of LEDs mounted on the circuit board.

또한, 광투과부재(91)의 하측에는 컨트롤패널(20)의 후면 일측에 형성된 배 출리브(24)가 안착될 수 있도록 안착홈(95)이 형성되는데, 가이드돌기(94)와 가이드홈(23)에 의해 안내된 물은 배출리브(24)에 형성된 배출홀(25)을 통해 배출된다.A receiving groove 95 is formed on the lower side of the light transmitting member 91 so that an emitting rib 24 formed on one side of the rear surface of the control panel 20 can be seated. 23 are discharged through the discharge hole 25 formed in the discharge rib 24.

즉, 본 발명의 실시예에서는 광투과부재 장착공(22)을 통해 유입된 외부의 물이 원통형상으로 이루어진 가이드돌기(94)와 가이드홈(23)에 의해 안내되어 광투과부재(91)의 하측으로 이동된다. That is, in the embodiment of the present invention, the external water introduced through the light transmitting member mounting hole 22 is guided by the cylindrical guide projections 94 and the guide grooves 23, And is moved downward.

그리고, 상기와 같이 가이드돌기(94)와 가이드홈(23)에 의해 광투과부재(91)의 하측으로 이동된 물은 광투과부재(91)의 안착홈(95)에 안착된 배출리브(24)에 형성된 배출홀(25)을 통해 배출된다.The water moved downward by the guide projection 94 and the guide groove 23 to the lower side of the light transmitting member 91 is discharged to the discharge ribs 24 (Not shown).

따라서, 본 발명의 실시예에서는 광투과부재 장착공을 통해 유입된 물이 가이드돌기와 가이드홈 및 배출리브로 이루어진 가이드부재에 의해 회로기판 측으로 이동되는 것을 방지함으로써 회로기판이 손상되는 것을 사전에 방지할 수 있는 것이다.Therefore, in the embodiment of the present invention, it is possible to prevent the water introduced through the light transmitting member mounting hole from being moved toward the circuit board by the guide member formed of the guide protrusion, the guide groove and the discharge rib, It is.

이상에서 설명한 바와 같이 본 발명에 따른 드럼세탁기는 가이드부에 의해 광투과부재 장착공을 통해 유입된 물에 의해 회로기판이 손상되는 것을 방지할 수 있는 효과가 있다.As described above, the drum washing machine according to the present invention has the effect of preventing the circuit board from being damaged by the water introduced through the light transmitting member mounting hole by the guide portion.
