세탁기의 PCB모듈PCB module of washing machine

본 고안은 세탁기의 PCB모듈에 관한 것으로, 더욱 상세하게는 세탁기에 적용되어지는 PCB모듈의 상.하부케이스가 간편하면서도 상호 긴밀하게 끼움결합될수 있도록 구성되어 상기 상.하부케이스의 결합면에 방수처리를 하기위한 별도의 몰딩작업을 배재시킬수 있도록 한 세탁기의 PCB모듈에 관한 것이다.The present invention relates to a PCB module of a washing machine, and more particularly, the upper and lower cases of the PCB module to be applied to the washing machine are configured to be easily and tightly coupled to each other, thereby waterproofing the coupling surfaces of the upper and lower cases. It relates to a PCB module of a washing machine so that a separate molding operation for dismantling.

일반적으로 전자동세탁기는 오염된 세탁물이 세탁기의 세탁조내에 투입되어지게 되면 세탁기의 상부판 일측에 장착되어진 조작부를 조작하여 상기 조립되어진 세탁물의 양에 맞게 상기 세탁조내로 세탁수를 투입시키는 급수행정과: 상기 급수행정이 완료되면 세탁조의 바닥면에 장착되어진 펄세이터를 정.역구동시켜 세탁물을 세탁시키는 세탁행정과; 상기 세탁되어진 세탁물을 행굼시키는 행굼행정과; 상기 행굼되어진 세탁물를 탈수시키는 탈수행정이 전자동으로 이루어지면서 세탁물이 자동으로 세탁되는 것이다.In general, the automatic washing machine is a water supply administration for introducing the washing water into the washing tank in accordance with the amount of the assembled laundry by operating the operation unit mounted on one side of the upper plate of the washing machine when contaminated laundry is put into the washing tank of the washing machine; A washing stroke for washing the laundry by forward and reverse driving the pulsator mounted on the bottom of the washing tank when the stroke is completed; A rinse stroke for rinsing the washed laundry; The laundry is automatically washed while the dehydration operation for dehydrating the rinsed laundry is performed automatically.

한편, 상기 조작부에는 PCB모듈의 케이스내에 PCB기판이 장착되어 이 PCB기판을 통하여 세탁에 필요한 일련의 과정이 콘트롤되면서 세탁이 이루어지게 되는 것이며, 따라서 상기 PCB기판은 세탁기의 핵심부품에 속하면서 또한, 세탁과정에서 침투될수 있는 수분에 의해 오동작이 일어날수있어 상기 PCB는외부와 완전히 밀폐되는 구조로 제작되는 것이다.On the other hand, the operation unit is mounted on the PCB substrate in the case of the PCB module is controlled by a series of processes required for washing through the PCB substrate is to be washed, so that the PCB substrate belongs to the core parts of the washing machine, washing Malfunction may occur due to moisture that can penetrate in the process so that the PCB is manufactured in a structure that is completely sealed to the outside.

그러나 종래의 PCB기판은 첨부된 도면의 도1에 도시된 바와같이 PCB모듈(100)이 상.하부케이스(120)(140)내에 장착됨과 아울러 상기 하부케이스(140)내에 수용되어진 PCB기판(220)의 상면에는 폴리우레탄(Poly-urethane)을 도포하여 몰딩층(200)이 형성되도록 함으로서 상기 하부케이스(140)내에 수용된 PCB기판(220)으로 수분이 침투되는 것을 방지할수 있도록 한 것이다.However, in the conventional PCB, as shown in FIG. 1 of the accompanying drawings, the PCB module 100 is mounted in the upper and lower cases 120 and 140 as well as the PCB substrate 220 accommodated in the lower case 140.
