It relates to a water penetration prevention structure of.

일반적으로, 마찰이나 진동 등의 기계적 작용을 가하여 세탁물에 묻어 있는 때를 빼기 위한 세탁기는 도 1 내지 도 3에 도시한 바와같이, 세탁물을 수납시키기 위해 도시되지 않은 세탁조 및 이를 포함하는 수조가 내부에 마련된 본체(10)와, 본체(10) 하부에 결합되어 본체(10)를 지지하는 베이스(12) 그리고, 본체(10) 상부에 결합된 커버 톱(cover top)(14)과 이의 전, 후면에 고정되는 조작부 및 리드 톱 커버(lid top cover)(16)가 결합된 커버 톱 커버(18)로 구성된다.In general, a washing machine for removing a time when it is buried in the laundry by applying a mechanical action such as friction or vibration, as shown in Figures 1 to 3, a washing tank not shown to accommodate the laundry and a tank including the same The main body 10, the base 12 coupled to the lower part of the main body 10 to support the main body 10, and the cover top 14 coupled to the upper part of the main body 10, and the front and rear surfaces thereof. It consists of a cover top cover 18 coupled to the operation unit and a lid top cover 16 fixed to it.

조작부는 커버 톱(14) 전면에 다수의 고정나사(20)로 고정되는 조작판넬(22)과 이의 상부에 체결되는 기능키가 인쇄된 디스플레이 판넬(display panel)(24) 및 조작판넬(24) 하부에 체결되어 기능키의 입력신호를 동작부에 전달하도록 와이어(도시되지않음)가 연결된 회로기판(26)으로 마련된다.The operation unit is a display panel 24 and an operation panel 24 on which a control panel 22 fixed with a plurality of fixing screws 20 on the front of the cover top 14 and function keys fastened thereon are printed. It is provided as a circuit board 26 is connected to the lower portion is connected to the wire (not shown) to transmit the input signal of the function key to the operation unit.

상기의 커버 톱(14) 전면부에는 회로기판(26)이 수용되는 수용공간(14a)이 형성되고, 수용공간(14a) 내벽면에는 회로기판(26)을 바닥면에 대해 소정높이로 배치시킬 수 있도록 복수의 지지리브(28)가 부착되며, 커버 톱 커버(18)에는 세탁조내에 일정량의 물을 급수시키기 위하여 급수구(30)의 일단부가 노출된다. 그리고, 급수구(30)에는 급수량을 조절하기 위한 급수밸브 등의 동작부(도시되지않음)가 설치된다.An accommodating space 14a in which the circuit board 26 is accommodated is formed in the front portion of the cover top 14, and an inner wall surface of the accommodating space 14a is disposed at a predetermined height with respect to the bottom surface. A plurality of support ribs 28 are attached to each other, and one end of the water supply port 30 is exposed to the cover top cover 18 to supply a predetermined amount of water in the washing tank. And, the water supply port 30 is provided with an operating unit (not shown) such as a water supply valve for adjusting the water supply amount.

이와같이 구성된 세탁기는 수조 및 이에 포함된 세탁조를 수납한 본체(10) 상,하부에 각각 커버 톱(14)과 베이스(12)를 결합한 다음 커버 톱(14) 전면에는 회로기판(26)이 저부에 체결된 조작판넬(22)을 다수의 고정나사(20)로 조여 고정하고, 조작판넬(22) 상부에는 여러개의 기능키를 갖는 디스플레이 판넬(24)을 체결시킨다. 이때, 회로기판(26)은 커버 톱(14)의 수용공간(14a)에 부착된 지지리브(28) 상단면에 접촉시킨다.The washing machine configured as described above combines the cover top 14 and the base 12 to the upper and lower parts of the main body 10 containing the water tank and the washing tank included therein, and then the circuit board 26 is disposed on the bottom of the cover top 14. The fastened control panel 22 is tightened and fixed with a plurality of fixing screws 20, and the display panel 24 having a plurality of function keys is fastened to the top of the operating panel 22. At this time, the circuit board 26 is in contact with the upper surface of the support rib 28 attached to the receiving space 14a of the cover top 14.

그 후, 커버 톱(14) 후면에는 리드 톱 커버(16)가 결합된 커버 톱 커버(18)를 고정하여 세탁기의 조립을 완료한 상태에서 세탁조내에 수납된 세탁물의 조건에 적합하도록 디스플레이 판넬(24)에 일체로 성형된 기능키를 조작하면, 이의 조작신호는 회로기판(26)에 입력됨과 동시에 와이어를 통해 동작부로 전달되어 급수, 세탁. 배수 및 탈수기능의 모드별로 세탁기가 동작되면서 세탁물이 세탁된다.Thereafter, the cover top cover 18 having the lid top cover 16 coupled thereto is fixed to the rear surface of the cover top 14 so that the display panel 24 is adapted to the conditions of the laundry stored in the washing tank in the state where the washing machine is assembled.
