하부 체결부(16)는 하우징(11)의 하부모서리로 부터 후방으로 연장되며 후방단의 중앙에는 결합돌기(20)가 형성되어 있다.The lower fastening part 16 extends rearward from the lower edge of the housing 11 and a coupling protrusion 20 is formed at the center of the rear end.

회로기판(12)은 하우징(11)의 후방면의 좌측상부 모서리에 돌출된 보스(23)와 우측하부모서리에 돌출된 보스(24)에 나사(25, 26)에 의해서 부착된다.The circuit board 12 is attached to the boss 23 protruding from the upper left corner of the rear face of the housing 11 and the bosses 24 protruding from the lower right corner by screws 25 and 26.

회로기판(12)의 우측하부에는 하도어 개폐검출용 진공릴레이(27)가 위치하고 좌측상부에는 상도어 개폐검출용 진공릴레이(28)가 위치한다.The lower door opening and closing detection vacuum relay 27 is located at the lower right side of the circuit board 12, and the upper door opening and closing detection vacuum relay 28 is located at the upper left side.

또한 회로기판(12)의 중앙에는 상기 진공릴레이(27, 28)의 단자들을 회로기판(12)의 요홈(29)을 통하여 후방으로 인출시키는 단자안내부(30)가 위치한다.In the center of the circuit board 12, a terminal guide part 30 for drawing the terminals of the vacuum relays 27 and 28 to the rear through the groove 29 of the circuit board 12 is located.

제3도에는 본 고안의 도어스위치(10)가 냉장고의 사절판(4)의 삽입홈(5)에 삽입된 상태가 도시되는데, 하우징(11)의 상부체결부(13)는 삽입홈(5)의 상부지지리브(6)에 결합되게 삽입되어 상부체결부(13)의 비육부(17)위에 돌출된 결합돌기(21, 22)가 상부지지리브(6)의 후반단에 체결된다.3 shows a state in which the door switch 10 of the present invention is inserted into the insertion groove 5 of the trimming plate 4 of the refrigerator, and the upper fastening portion 13 of the housing 11 is an insertion groove 5. The coupling protrusions 21 and 22 which are inserted to be coupled to the upper support ribs 6 of the c) and protrude on the fattening part 17 of the upper fastening part 13 are fastened to the rear half of the upper support ribs 6.

하우징(11)의 측방체결부(14, 15)는 삽입홈(5)의 측면모서리(8, 9)에 결합되게 삽입되며 하우징(11)의 하부체결부(16)는 삽입홈(5)의 하부지지리브(7)에 결합되게 삽입되어 하부체결부(16)의 결합돌기(20)가 하부지지리브(7)의 후방단에 체결된다.The side fastening portions 14 and 15 of the housing 11 are inserted to be coupled to the side edges 8 and 9 of the insertion groove 5, and the lower fastening portion 16 of the housing 11 is inserted into the insertion groove 5. Inserted to be coupled to the lower support rib (7) is coupled to the engaging projection 20 of the lower fastening portion 16 is fastened to the rear end of the lower support rib (7).

한편, 회로기판(12)의 진공릴레이(28)는 하우징(11)의 상부에 위치하고 진공릴레이(27)는 하우징(11)의 상부에 위치하고 진공릴레이(27)는 하우징(11)의 하부에 위치하며 이들 진공릴레이의 단자는 냉장고의 IC제어부에 연결되어 있다.On the other hand, the vacuum relay 28 of the circuit board 12 is located in the upper portion of the housing 11, the vacuum relay 27 is located in the upper portion of the housing 11 and the vacuum relay 27 is located in the lower portion of the housing 11 The terminals of these vacuum relays are connected to the IC control unit of the refrigerator.

본 고안의 도어스위치(10)가 작동하는 것을 설명하면 다음과 같다.Referring to the operation of the door switch 10 of the present invention is as follows.

상도어(31)가 도어스위치(10)의 하우징(11)에 인접하게 닫히면 상도어(31)의 압구(32)에 내장된 자석이 도어 스위치(10)의 진공릴레이(28)의 접점을 접속시키고 이것이 냉장고의 IC 제어부에 전달된다.When the upper door 31 is closed adjacent to the housing 11 of the door switch 10, a magnet built into the pressure port 32 of the upper door 31 connects the contact of the vacuum relay 28 of the door switch 10. This is then passed to the IC control unit of the refrigerator.

반대로 상도어(31)가 도어스위치(10)의 하우징(11)으로 부터 멀리 개방되면 도어스위치(10)의 진공릴레이(28)의 접점은 자력의 범위를 벗어나므로 접점이 분리되고 이것이 냉장고의 IC제어부에 전달된다.On the contrary, when the top door 31 is opened far from the housing 11 of the door switch 10, the contact of the vacuum relay 28 of the door switch 10 is out of the magnetic force range, so the contact is separated and this is the IC of the refrigerator. It is delivered to the control unit.

한편, 하도어(33)가 도어스위치(10)의 하우징(11)에 인접하게닫히면 하도어(33)의 압구(34)에 내장된 자석이 도어스위치(10)의 진공릴레이(27)의 접점을 접속시키고 이것이 냉장고의 IC 제어부에 전달된다.On the other hand, when the lower door 33 is closed adjacent to the housing 11 of the door switch 10, the magnet built into the pressure port 34 of the lower door 33 is the contact of the vacuum relay 27 of the door switch 10. Is connected to the IC control unit of the refrigerator.

반대로 하도어(33)가 도어스위치(10)의 하우징(11)으로 부터 멀리 개방되면 도어스위치(10)의 전공릴레이(27)의 접점은 자력의 범위를 벗어나므로 접점이 분리되고 이것이 냉장고의 IC제어부에 전달된다.On the contrary, when the lower door 33 is opened far from the housing 11 of the door switch 10, the contact of the electric relay 27 of the door switch 10 is out of the range of magnetic force, so the contact is separated and this is the IC of the refrigerator. It is delivered to the control unit.

상기와 같이 구성된 본 고안의 도어스위치는 진공 릴레이를 도어의 입구에 내장된 자석으로 동작시키므로 접점이 마모되는 불량원인을 발생시키지 않으며 도어의 개폐작동에도 전혀 영향을 주지 않는 우수한 효과를 제공한다.The door switch of the present invention configured as described above operates the vacuum relay with a magnet built into the inlet of the door, so that the contact point does not cause a bad cause of wear and does not affect the opening and closing operation of the door at all.
