The present invention relates to a printed circuit board mounting structure of a washing machine that can be molded evenly on the entire surface of a PCB because the molding process is performed in a state where the mold is fixed and fixed to the case.
제1도에 개략적으로 도시된 바와같이, 종래 기술에 의한 세탁기의 인쇄회로기판 몰딩성형시 이용되는 케이스는, 미도시된 세탁기 몸체 상측에 상부커버(1)가 개폐가능하게 힌지고정되며, 상부커버(1)일측에 세탁, 헹굼, 탈수행정 등의 세탁행정을 미리 프로그램화 시켜두어 사용자의 버튼 조작에 의해 선택적으로 제어하는 콘트롤부를 형성하는 PCB(2)가 케이스(3)에 내설되어 장착된다.As schematically shown in Figure 1, the case used for molding a printed circuit board of the washing machine according to the prior art, the upper cover (1) is hinged to open and close the upper part of the washing machine body not shown, the upper cover (1) On one side, a PCB (2) is installed in the case (3) which forms a control unit for pre-programming washing strokes such as washing, rinsing, and dehydrating strokes and selectively controlling them by user's button operation.
전술한 PCB(2)를 케이스(3)에 장착시 세탁기의 사용도중 물, 습기 등에 의해 PCB(2)에 장착되는 미도시된 단자들의 쇼트됨을 방지하기 위해 PCB(2) 표면에 우레탄 몰딩처리를 하게 된다.When the PCB 2 is mounted on the case 3, a urethane molding is applied to the surface of the PCB 2 to prevent shorting of terminals not mounted on the PCB 2 due to water or moisture during use of the washing machine. Done.
즉, 케이스(3) 바닥면에 미경화된 반고체상태(Jell 상태)의 우레탄을 소정량 투입한 다음, 우레탄 표면에 PCB(2)를 재치시켜 PCB(2)를 체결하는 위치에 착탈가능하게 고정되는 미도시된 가압봉을 이용하여 PCB(2)를 가압하게 되며, 이로인해 PCB(2)와 케이스(3) 사이에 수용된 우레탄 일부가 PCB(2) 상면에 올라와 경화됨으로써 PCB(2) 표면은 몰딩 처리된다.That is, a predetermined amount of uncured semi-solid urethane (Jell state) of urethane is injected into the bottom of the case 3, and then the PCB 2 is placed on the urethane surface to be detachably fixed at the position where the PCB 2 is fastened. Pressing the PCB (2) by using a pressure bar, which is not shown, thereby causing a part of the urethane contained between the PCB (2) and the case (3) to rise on the upper surface of the PCB (2) and harden the surface of the PCB (2). Molding process.
이때, PCB(2)는 케이스(3) 바닥면 모서리에 형성된 수개의 받침부재(3A)에 의해 수평상태를 유지하여 PCB(2)의 표면이 균일하게 몰딩처리되도록 한 것이다.At this time, the PCB 2 is kept horizontal by several supporting members 3A formed at the bottom edge of the case 3 so that the surface of the PCB 2 is uniformly molded.
그러나, 전술한 PCB(2) 표면의 몰딩처리시 가압봉의 가압력이 PCB(2)의 전 표면에 대해 일정치 않게 작용되므로, 케이스(3)에 형성된 받침부재(3A)상에 안착되는 PCB(2)의 일측이 우레탄 투입으로 받침부재(3A)으로부터 이격된 상태에서 몰딩처리되는 경우, 케이스(3)에 대해 PCB(2)가 비수평상태로 형성되므로 세탁기의 상부커버(1)에 대해 장착되어 사용할 때 PCB(2)상에 장착되어 각각의 기능을 갖는 버튼을 조작하는 조작력이 불균일해 사용감도가 떨어져 제품의 신뢰도가 저하되는 것이다.However, since the pressing force of the pressure bar is invariably acted on the entire surface of the PCB 2 during the molding process of the surface of the PCB 2 described above, the PCB 2 seated on the support member 3A formed in the case 3. When one side of the) is molded in a state spaced apart from the support member 3A by urethane input, the PCB 2 is formed in a non-horizontal state with respect to the case 3 so that it is mounted to the upper cover 1 of the washing machine. When used, it is mounted on the PCB (2), the operation force for manipulating the buttons having the respective functions is uneven, the use sensitivity is lowered, the reliability of the product is lowered.
따라서, 본 고안의 목적은, 세탁기의 상부커버에 장착되어 세탁행정을 제어하는 콘트롤부를 형성하는 케이스에 대해 PCB가 수평상태를 유지하여 몰딩표면처리되어 장착되므로 상부커버에 장착되어 사용할때 PCB상에 장착되는 다수의 조작버튼 각각의 조작력이 균일해 신뢰도를 향상시킬 수 있도록 한 세탁기의 인쇄회로기판 취부구조를 제공하는 것이다.Therefore, an object of the present invention, the PCB is mounted on the upper cover of the washing machine to form a control unit for controlling the washing administration, so that the molding surface treatment is mounted on the PCB when it is mounted on the upper cover when used It is to provide a printed circuit board mounting structure of a washing machine so that the operation force of each of the plurality of operation buttons to be mounted is uniform to improve reliability.
전술한 본 고안의 목적은, 세탁기의 상부커버 소정위치에 장착되는 콘트롤부의 케이스에 대해 인쇄회로기판을 몰딩피막처리하여 고정하는 인쇄회로기판의 취부구조에 있어서, 상기 케이스 내부 바닥면 모서리에 형성되어 상기 인쇄회로기판의 몰딩시 인쇄회로기판의 수평상태를 유지하는 받침부재와, 상기 받침부재와 대향되게 상기 케이스 내부측벽에 형성되어 상기 인쇄회로기판의 몰딩시 상기 받침부재로부터 인쇄회로기판의 이탈됨을 방지하는 스토퍼를 구비하여 구성됨을 특징으로 하는 세탁기의 인쇄회로기판 취부구조를 제공함에 의해 달성된다.The object of the present invention described above, in the mounting structure of the printed circuit board for fixing the printed circuit board by molding the coating to the case of the control unit mounted on a predetermined position of the upper cover of the washing machine, is formed in the bottom edge of the inside of the case A supporting member which maintains a horizontal state of the printed circuit board when the printed circuit board is molded, and formed on an inner side wall of the case so as to face the supporting member so that the printed circuit board is separated from the supporting member when the printed circuit board is molded. It is achieved by providing a printed circuit board mounting structure of a washing machine, characterized in that it is provided with a stopper to prevent.
이하, 본 고안의 바람직한 일실시예를 첨부도면에 따라 상세하게 설명한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안에 의한 세탁기의 PCB 몰딩 성형시 이용되는 케이스의 개략적인 사시도이며, 제3도는 본 고안에 의해 몰딩처리된 인쇄회로기판의 고정상태도이다.2 is a schematic perspective view of a case used for molding a PCB of a washing machine according to the present invention, and FIG. 3 is a fixed state diagram of a printed circuit board molded by the present invention.
도면에 도시된 바와같이, 세탁기의 상부커버(1) 소정위치에 장착되며 세탁행정을 사용자가 선택적으로 조작할 수 있도록 미리 프로그램화 시켜둔 콘트롤부의 케이스(4) 내부 바닥면 모서리에 수개의 받침부재(5)가 일체로 형성되며, 받침부재(5)상에 안착되어 케이스(4)내부 바닥에 투입되는 반고체상태의 우레탄에 의해 피막처리시 PCB(2)가 받침부재(5)로부터 이격됨을 방지하는 스토퍼(6)가 케이스(4) 내벽에 받침부재(5)와 각각 대향되게 일체로 형성된다.As shown in the figure, several supporting members are mounted at the upper cover 1 of the washing machine at a predetermined position and in the bottom edge of the inner surface of the case 4 of the control unit which is pre-programmed to allow the user to selectively operate the washing stroke. (5) is integrally formed, and is prevented from being separated from the support member (5) during the coating process by the semi-solid urethane that is seated on the support member (5) and put into the bottom of the case (4) The stopper 6 is integrally formed on the inner wall of the case 4 so as to face the supporting member 5, respectively.
위와같이 구성되는 본 고안에 의한 세탁기의 인쇄회로기판의 취부순서를 설명하면, 세탁기몸체의 상부에 개폐가능하게 장착되는 상부커버(1) 소정위치에 장착되는 콘트롤부의 케이스(4) 내부 바닥면에 미경화된 반고체상태의 우레탄을 투입한 다음, 우레탄 상에 PCB(2)를 재치시켜 PCB(2) 상면을 도구를 이용해 가압하게 됨에 따라 PCB(2)는 케이스(4) 바닥면 모서리에 형성된 받침부재(5)상에 안착되어 수평상태를 유지하게 된다.Referring to the mounting procedure of the printed circuit board of the washing machine according to the present invention configured as described above, the upper cover (1) mounted on the upper part of the washing machine body to be openable and closed on the case 4 of the inner bottom surface of the control unit mounted at a predetermined position As the uncured semi-solid urethane is added, the PCB 2 is placed on the urethane to press the upper surface of the PCB 2 with a tool, so that the PCB 2 is formed at the bottom edge of the case 4. It is mounted on the member 5 to maintain a horizontal state.
이때, 케이스(4) 바닥면에 투입되는 굳지 않는 상태의 우레탄에 의해 유동되는 PCB(2)는 받침부재(5)와 대향되게 케이스(4)내부 측벽에 형성된 스토퍼(6)에 의해, PCB(2)의 우레탄 피막처리시 PCB(2)는 받침부재(5)로부터 이격됨이 방지되며, PCB(2)를 가압시 이용되는 도구는 PCB(2)가 받침부재(5)와 스토퍼(6) 사이에 안착시 PCB로부터 이탈되는 것이며, 이는 종래의 PCB(2)에 고정되어 우레탄이 굳을때까지 고정되는 것과는 전혀 상이한 것이다.At this time, the PCB (2) flowed by the urethane in the hardened state that is put into the bottom surface of the case (4) by the stopper (6) formed on the inner side wall of the case (4) facing the support member (5), the PCB ( In the urethane coating of 2), the PCB 2 is prevented from being spaced apart from the supporting member 5, and the tool used when pressing the PCB 2 is the PCB 2 supporting the supporting member 5 and the stopper 6 It is separated from the PCB when settled in between, which is completely different from being fixed to the conventional PCB (2) until the urethane is solidified.
따라서, PCB(2)는 케이스(4)내부에 표면이 균일하게 몰딩처리되면서 수평상태를 유지하여 고정되는 것이다.Therefore, the PCB 2 is fixed while maintaining a horizontal state while the surface of the case 4 is uniformly molded.
이상에서와 같이, 본 고안에 의해 세탁기의 인쇄회로기판 취부구조는, 세탁기의 상부커버 소정위치에 장착되는 콘트롤부케이스에 대해 PCB를 몰딩피막처리하면서 고정하는 경우 PCB의 전 표면에 대해 균일하게 몰딩처리되므로, 콘트롤부에 장착되는 각각의 조작버튼의 조작력이 균일해 사용감도가 뛰어나 제품의 신뢰도를 향상시키는 이점과, 케이스의 몰딩피막처리시 불량발생률을 줄여 생산성을 향상시키는 이점을 갖게된다.As described above, according to the present invention, the printed circuit board mounting structure of the washing machine is uniformly molded over the entire surface of the PCB when the PCB is fixed to the control part case mounted at the predetermined position of the upper cover of the washing machine. Since it is processed, the operation force of each operation button mounted on the control unit is uniform, and thus the use sensitivity is excellent, thereby improving the reliability of the product and reducing the incidence of defects during the molding coating of the case, thereby improving productivity.
