Description

냉장고용 제상 타이머의 스위치 구조Switch structure of defrost timer for refrigerator

본 고안은 냉장고용 성에제거용 타이머의 스위치 구조에 관한 것이다.The present invention relates to a switch structure of a defrosting timer for a refrigerator.

냉장고는 증발기를 통하여 냉매가 흡열작용을 할 때, 주변공기중의 습기나 보관식품에 함유된 습기등이 증발기의 주변으로 응결되어 성에가 형성되므로 이 성에가 증발기의 표면을 덮게 되어 냉동효율이 저하되는 원인이 되기 때문에 이를 적절히 제거하여 주어야 된다.When the refrigerant absorbs heat through the evaporator, moisture in the surrounding air or moisture contained in the stored food condenses around the evaporator to form frost, which causes the frost to cover the surface of the evaporator, thus reducing the freezing efficiency. It must be removed properly because it is a cause.

냉장고 분야에서 실용화되고 있는 성에제거장치는 여러형태의 것이 있으나, 그 중 일정시간마다 자동으로 성에를 제거하는 타이머식이 있다.Defrosting devices that have been put to practical use in the refrigerator field are of various types, among which there is a timer type that automatically removes the frost every predetermined time.

기존의 타이머식 성에제거장치의 타이머는 모터와 감속 연결된 회전축에 2단의 돌출캠을 축삽 형성하고, 이에 냉동접점단자와 제상접점단자를 연동 작동케하여 이를 전원접점단자와 교번의 접촉케하여 일정 간격으로 냉동작동과 제상작용을 교번으로 작동케 한다.The timer of the conventional timer defroster is formed by inserting two-stage protruding cams on the rotating shaft connected to the motor and decelerating them, and interlocking the freezing contact terminal and the defrosting contact terminal to make contact with the power contact terminal alternately. At intervals, the freezing and defrosting work alternately.

전기한 종래의 냉장고용 제상타이머 스위치 구조는 2단의 캠을 이용하여 두접점단자를 연동케 하는 것이어서 그만큼 설치구조가 복잡하고 커지는 문제가 있고, 캠의 역회전 방지구조가 없어 스위치의 턴온시에 반대방향으로 회전시킬 수도 있어 정확한 제어가 곤란한 문제가 있다.The conventional defrost timer switch structure for refrigerators uses two-stage cams to interlock two contact terminals, so that the installation structure is complicated and large, and there is no cam reverse rotation prevention structure. It may be rotated in the opposite direction, there is a problem that accurate control is difficult.

본 고안은 제상타이머의 스위치 구조에 있어서, 전기한 바와 같은 문제점을 제거코저 회전축에 삽입되는 캠을 캠홈을 갖는 1단으로 형성하고, 이에 중간의 전원 접촉단자가 연동되게 하므로서 그 구성을 간략화하고, 하부에 역회전 방지기능을 부가하여 역회전으로 인한 제어의 부실을 방지되게한 냉장고용 제상 타이머스위치 구조를 제공함에 고안의 목적이 있다.The present invention, in the switch structure of the defrosting timer, eliminates the above-described problems, and forms a cam inserted into the rotary shaft of the decoupling in one stage having a cam groove, and simplifies its configuration by allowing an intermediate power contact terminal to interlock with it. It is an object of the present invention to provide a defrost timer switch structure for a refrigerator that prevents the insolvency of the control due to the reverse rotation by adding a reverse rotation prevention function at the bottom.

전기한 목적을 위한 기술수단으로 회전축에 캠홈을 갖는 캠판과 역회전 방지수단을 부설한다.As a technical means for the foregoing purpose, a cam plate having a cam groove on the rotating shaft and a reverse rotation preventing means are provided.

이하, 본 고안의 실시예에 의하여 상세히 설명한다.Hereinafter, the embodiment of the present invention will be described in detail.

제1도는 본 고안 타이머의 정면개략도이다.1 is a schematic front view of the present invention timer.

본체(1)내 모터(2)의 회전기어(3)로부터 감속 연결된 회전축(4)에 캠홈(5)이 형성된 캠판(6)을 삽입하고, 그 측부 전원접점단자(7)와 냉동접점단자(8) 및 제상접점단자(9)를 설치하되, 중간의 전원접점단자(7)가 캠판(6)에 연동되게 한다.A cam plate 6 having a cam groove 5 is inserted into the rotary shaft 4 which is decelerated and connected from the rotary gear 3 of the motor 2 in the main body 1, and the side power contact terminal 7 and the freezing contact terminal ( 8) and the defrosting contact terminal 9 is installed so that the intermediate power contact terminal 7 is interlocked with the cam plate 6.

제2도는 본 고안 스위치 부분을 분리표시한 사시도이고, 제3도는 그 결합상태의 단면 설명도이다.FIG. 2 is a perspective view of the switch part of the present invention separated from each other, and FIG.

회전축(4)에 캠홈(5)이 형성된 1개의 캠판(6)을 축삽하여, 이에 전원접점단자(7)가 연동되게 하고, 회전축(4)의 하부에는 회전원판(10)을 형성하여 홀(11)(11′)을 원형으로 연속 형성하고, 그 하부의 기어(12) 보스(13)에 경사면을 갖는 계지턱(14)이 형성된 탄성레버(15)를 형성한다.A cam plate 6 having a cam groove 5 formed therein is inserted into the rotating shaft 4 so that the power contact terminal 7 is interlocked, and a rotating disc 10 is formed below the rotating shaft 4 to form a hole ( 11) (11 ') are continuously formed in a circular shape, and the elastic lever 15 in which the latching jaw 14 which has the inclined surface was formed in the gear 12 and the boss 13 of the lower part is formed.

이와 같이 구성된 본 고안의 작용을 설명한다.The operation of the present invention configured as described above will be described.

타이머를 작동시키면 모터(2)가 회전되면서 감속기어군을 통해 회전축(4)이 저속 회전하게 된다.When the timer is operated, the rotating shaft 4 rotates at a low speed through the reduction gear group while the motor 2 rotates.

회전축(4)의 저속회전으로 그 축상에 축삽된 캠판(6) 역시 저속 회전하게 된다.The low speed rotation of the rotary shaft 4 also causes the cam plate 6 inserted on the shaft to rotate at low speed.

이때 캠판(6)의 원주면에 접촉되어 있는 전원접점단자(7)가 뒤쪽으로 휘어 냉동접점단자(8)와 접속케 되므로 냉장고의 냉동작용이 이루어지고, 일정 시간이 경과되어 캠홈(5)이 전원접점단자(7)의 위치에 이르게 되면 전원접점단자(7)가 그 단자 자체의 탄성에 의해 캠홈(5)으로 요입되어 전원접점단자(7)가 냉동접점단자(8)로부터 분리되면서 반대편의 제상접점단자(9)와 접속되게 되어 제상히터를 작동시키므로서 하나의 캠판 및 하나의 접접단자의 접속과 분리에 의해 성에를 제거할 수 있는 것이다.At this time, since the power contact terminal 7 which is in contact with the circumferential surface of the cam plate 6 is bent backwards and connected to the freezing contact terminal 8, the freezing operation of the refrigerator is performed, and a predetermined time has elapsed so that the cam groove 5 is When the power contact terminal 7 reaches the position of the power contact terminal 7, the power contact terminal 7 is inserted into the cam groove 5 by the elasticity of the terminal itself, so that the power contact terminal 7 is separated from the freezing contact terminal 8, Defrost contact terminal 9 is connected to the defrosting heater by operating the defrosting by connecting and disconnecting one cam plate and one contact terminal.

또 회전축(4)의 하단에 회전원판(10)이 형성되고, 그 표면에 홀(11)(11′)이 형성되어 있어 하부의 기어(12) 보스(13)에 형성된 탄성레버(15)의 계지턱(14)과 치합되므로서 제4도의 도시와 같이 계지턱(14)의 경사방향인 일방향으로만 이동이 가능하고 반대방향으로의 이동을 차단하므로서 조정 레버의 역회전을 방지하여 정확한 조정이 가능한 것이다.In addition, the rotary disk 10 is formed at the lower end of the rotary shaft 4, and holes 11 and 11 'are formed on the surface thereof, so that the elastic lever 15 formed in the boss 12 of the lower gear 12 is formed. As shown in FIG. 4, the engaging jaw 14 can be moved only in one direction in the inclined direction of the locking jaw 14, and the movement in the opposite direction is prevented by preventing the reverse rotation of the adjustment lever. It is possible.

이상과 같이 본 고안은 냉장고용 제상타이머에 있어서, 스위치구조를 개선하므로서 타이머의 소형화와 단순화를 이루고 고장의 우려등을 없애 냉장고의 성에를 효율적으로 제거할 수 있는 효과가 있다.As described above, in the refrigerator defrost timer, the present invention has an effect of minimizing and simplifying the timer by eliminating the fear of failure by improving the switch structure and effectively eliminating the frost of the refrigerator.
