본 발명에 따른 워셔액 히팅장치용 피티씨조립체는 도 1 내지 도 3에서 도시된 바와 같이, 절연프레임(10), 발열소자(20), 전극플레이트(30) 및 방열프레임(40)을 포함한다. The PC assembly for a washer liquid heating device according to the present invention includes an insulating frame 10, a heating element 20, an electrode plate 30, and a radiating frame 40, as shown in FIGS. 1 to 3.

절연프레임(10)은 발열소자(20)가 설치되는 공간을 제공하도록 관통홀부(11)가 형성된다. The insulating frame 10 is formed with a through hole 11 to provide a space in which the heating element 20 is installed.

그리고, 발열소자(20)는 관통홀부(31)에 배치되어 열을 발생시킨다. 이때, 발열소자(31)는 온도가 올라가다가 일정 온도가 되면 급격히 저항이 올라가는 특징을 가지는 서미스터로 이루어진다. In addition, the heating element 20 is disposed in the through hole 31 to generate heat. At this time, the heating element 31 is made of a thermistor having a characteristic that the resistance increases rapidly when the temperature rises and then reaches a certain temperature.

즉, 발열소자(20)는 적정 전압을 인가시 주위 온도 및 방열 조건에 따라 자가 조절(Self Regulation) 기능을 가지고 있어 별도의 컨트롤러 없이도 일정 온도를 유지한다.That is, the heating element 20 has a self-regulation function according to the ambient temperature and heat dissipation conditions when an appropriate voltage is applied, and thus maintains a constant temperature without a separate controller.

그리고, 전극플레이트(30)는 발열소자(20)의 양측을 커버하도록 절연프레임(10)에 결합되어 발열소자(20)에 전원을 인가한다. 이때, 전극플레이트(30)는 고정결합부(50)에 의해 절연프레임(10)에 고정될 수 있다. 이러한 고정결합부(50)는 절연프레임(10)에 형성되는 끼움홈부(51)와, 끼움홈부(51)에 끼워지도록 전극플레이트(30)에 구비되는 끼움부재(52)를 포함한다. 이러한 끼움부재(32)는 끼움홈부(31)에 삽입시 탄성적으로 지지되어 전극플레이트(30)의 이탈을 방지하도록 경사지게 형성될 수 있다.Further, the electrode plate 30 is coupled to the insulating frame 10 to cover both sides of the heating element 20 to apply power to the heating element 20. In this case, the electrode plate 30 may be fixed to the insulating frame 10 by the fixing coupling part 50. The fixed coupling portion 50 includes a fitting groove portion 51 formed in the insulating frame 10 and a fitting member 52 provided in the electrode plate 30 so as to be fitted in the fitting groove portion 51. The fitting member 32 may be elastically supported when inserted into the fitting groove 31 and may be formed to be inclined to prevent separation of the electrode plate 30.

또한, 전극플레이트(30)는 고정결합부(50)를 통해 절연프레임(10)에 고정 결합시 전극플레이트(30)를 절연시키는 동시에 고정력을 보강하도록 절연테이프(31)가 부착된다.In addition, when the electrode plate 30 is fixedly coupled to the insulating frame 10 through the fixed coupling portion 50, an insulating tape 31 is attached to insulate the electrode plate 30 and at the same time reinforce the fixing force.

이때, 발열소자(20)는 이탈방지결합부(60)에 의해 관통홀부(11)에 이탈 방지 가능하게 삽입될 수 있다. 이를 위해, 전극플레이트(30)에는 발열소자(20)를 커버하는 부위에 접촉부재(32)가 구비되고, 이탈방지결합부(60)는 발열소자(20)의 가장자리를 지지하도록 관통홀부(11)의 일측 개방부위에 상호 마주보게 형성되는 걸림턱부(61) 및 관통홀부(11)에 발열소자(20)가 강제적으로 삽입되도록 관통홀부(11)의 타측 개방부위에 상호 마주보게 형성되는 걸림돌기부(62)를 포함한다.In this case, the heating element 20 may be inserted into the through hole 11 by the separation preventing coupling part 60 so as to prevent separation. To this end, the electrode plate 30 is provided with a contact member 32 at a portion covering the heating element 20, and the separation preventing coupling portion 60 is a through-hole 11 to support the edge of the heating element 20. A locking protrusion formed to face each other on the other open portion of the through-hole 11 so that the heating element 20 is forcibly inserted into the through-hole 11 and the locking protrusion 61 formed to face each other at one open portion of) Includes 62.

이로써, 발열소자(20)는 전극플레이트(30)를 절연프레임(10)에 고정시키기 전에 관통홀부(11)에 배치된 상태를 유지할 수 있으므로, 조립의 작업성을 향상시킬 수 있게 된다.As a result, the heating element 20 can maintain a state disposed in the through-hole 11 before fixing the electrode plate 30 to the insulating frame 10, so that the workability of assembly can be improved.

한편, 방열프레임(40)은 발열소자(20)에서 발생된 열을 흡수하여 외부로 전달하도록 절연프레임(10)의 둘레면을 감싼다. 이때, 방열프레임(40)은 절연프레임(10)의 일측을 수용하는 제1방열프레임(41)과 절연프레임(10)의 타측을 수용하는 제2방열프레임(42)으로 이루어지고, 제1방열프레임(41)과 제2방열프레임(42)은 압착결합부(70)에 의해 상호 결합된다. Meanwhile, the heat dissipation frame 40 surrounds the circumferential surface of the insulating frame 10 so as to absorb heat generated by the heating element 20 and transmit it to the outside. At this time, the radiating frame 40 is composed of a first radiating frame 41 accommodating one side of the insulation frame 10 and a second radiating frame 42 accommodating the other side of the insulation frame 10, and The frame 41 and the second heat dissipating frame 42 are coupled to each other by a compression coupling portion 70.

여기서, 압착결합부(70)는 제1방열프레임(41)과 제2방열프레임(42)에 구비되는 압착돌기부(71) 및 압착돌기부(71)가 삽입되도록 제2방열프레임(42)과 제1방열프레임(41에 형성되는 압착홈부(72)를 포함한다. 이때, 압착돌기부(37a)는 압착홈부(37b)에 삽입시 압착홈부(72)로부터 이탈 방지되도록 압착홈부(72)의 폭보다 크게 형성된다. Here, the compression coupling portion 70 is the second heat dissipation frame 42 and the second heat dissipation frame 42 and the second heat dissipation frame 42 so that the crimping protrusion 71 and the crimping protrusion 71 provided in the first and 1 Includes a compression groove 72 formed in the heat dissipation frame 41. At this time, the compression protrusion 37a is less than the width of the compression groove 72 to prevent separation from the compression groove 72 when inserted into the compression groove 37b. It is largely formed.

즉, 제1방열프레임과(41)과 제2방열프레임(42)는 압착돌기부(71)와 압착홈부(72)의 압착 결합으로 상호 맞닿아면서 수용홀부(43)를 형성한다. 여기서, 수용홀부(43)는 절연프레임(10)이 이탈 방지 가능하게 수용될 수 있도록 폭, 길이, 너비 등이 절연프레임(10)에 대응되도록 형성된다.That is, the first heat dissipation frame 41 and the second heat dissipation frame 42 are in contact with each other by the compression coupling of the compression protrusion 71 and the compression groove 72 to form the receiving hole 43. Here, the receiving hole 43 is formed to have a width, a length, a width, etc. corresponding to the insulating frame 10 so that the insulating frame 10 can be accommodated so as to prevent separation.

이때, 절연프레임(10)은 방열프레임(40)에 수용시 방열프레임(40)의 일측에 돌출 가능하게 배치되는 파지부(12)가 구비된다. 즉, 파지부(12)는 제1방열프레임(41)과 제2방열프레임(42)을 압착 조립하기 전에 절연프레임(10)의 정렬을 안내하는 역할을 수행한다.In this case, the insulating frame 10 is provided with a gripping portion 12 disposed to be protruded on one side of the heat radiation frame 40 when accommodated in the heat radiation frame 40. That is, the gripping part 12 serves to guide the alignment of the insulating frame 10 before pressing and assembling the first heat dissipating frame 41 and the second heat dissipating frame 42.

아울러, 제1방열프레임(41)과 제2방열프레임(42)의 둘레면에는 방열강화부재(44)가 돌출 형성된다. 이에 따라, 제1방열프레임(41)과 제2방열프레임(42)은 발열소자(20)의 열을 외부로 방출시 열을 발산시킬 수 있는 면적이 증가됨으로써, 워셔액의 가열 속도를 향상시킬 수 있게 된다.In addition, a heat dissipation reinforcing member 44 is protruded on the circumferential surfaces of the first and second radiating frames 41 and 42. Accordingly, the first heat-radiating frame 41 and the second heat-radiating frame 42 increase the area capable of dissipating heat when dissipating heat from the heat generating element 20 to the outside, thereby improving the heating rate of the washer fluid. There will be.
