Description

냉장고의 방열콘덴서 냉각팬모터 제어회로Radiator capacitor cooling fan motor control circuit of refrigerator

본 발명은 냉장고의 방열콘덴서 냉각팬모터 제어회로에 관한 것으로, 특히 외부의 온도가 설정치 이하일때는 그 방열콘덴서 냉각팬모터를 동작시키지 않은 냉장고의방열콘덴서 냉각팬모터 제어회로에 관한 것이다.The present invention relates to a heat dissipation capacitor cooling fan motor control circuit of a refrigerator, and more particularly, to a heat dissipation capacitor cooling fan motor control circuit of a refrigerator in which the heat dissipation capacitor cooling fan motor is not operated when the outside temperature is lower than a set value.

종래 냉장고의 방열콘덴서 냉각팬모터는 압축기 모터와 병렬접속되어 압축기 모터가 동작하는 동안에는 계속동작을 하였으며, 이와 같은 종래 냉장고의 방열콘덴서 냉각팬모터 제어회로를 첨부한 도면을 참조하여 상세히 설명하면 다음과 같다.The heat dissipation capacitor cooling fan motor of the conventional refrigerator is connected in parallel with the compressor motor and continues to operate while the compressor motor is operating. The heat dissipation capacitor cooling fan motor control circuit of the conventional refrigerator will be described in detail with reference to the accompanying drawings. same.

도1은 종래 냉장고의 방열콘덴서 냉각팬모터 제어회로도로서, 이에 도시된 바와 같이 마이크로 컴퓨터(MC1)의 출력신호인 제어신호(CNTRL1)를 인버터(INV1)를 통해 인가받아 동작제어되는 계전기(RY1)와; 상기 계전기(RY1)의 동작에 따라 전원전압(POWER)을 인가받아 구동되는 병렬접속된 압축기 모터(COMP1) 및 방열콘덴서 냉각팬모터(M1)로 구성된다.1 is a circuit diagram of a cooling fan motor control circuit of a conventional refrigerator. As shown in FIG. 1, a relay RY1 is controlled by receiving a control signal CNTRL1, which is an output signal of a microcomputer MC1, through an inverter INV1. Wow; In accordance with the operation of the relay (RY1) is composed of a parallel-connected compressor motor (COMP1) and a heat radiation capacitor cooling fan motor (M1) that is driven by the power supply voltage (POWER).

이하, 상기와 같이 구성된 종래 냉장고의 방열콘덴서 냉각팬모터 제어회로의 동작을 설명한다.Hereinafter, the operation of the heat radiation capacitor cooling fan motor control circuit of the conventional refrigerator configured as described above will be described.

먼저, 마이크로 컴퓨터(MC1)의 제어신호(CNTRL1)가 저전위로 출력되면, 그 마이크로 컴퓨터(MC1)의 제어신호(CNTRL1)를 인버터(INV1)를 통해 인가받은 계전기(RY1)는 오프된다. 이에따라 전압전원(POWER)이 상호 병렬접속된 압축기 모터(COMP1)와 방열콘덴서 냉각팬모터(M1)에 인가되지 않기 때문에, 그 압축기 모터(COMP1)와 방열콘덴서 냉각팬모터(M1)는 동작하지 않는다.First, when the control signal CNTRL1 of the microcomputer MC1 is output at a low potential, the relay RY1 applied to the control signal CNTRL1 of the microcomputer MC1 through the inverter INV1 is turned off. Accordingly, since the voltage power POWER is not applied to the compressor motor COMP1 and the heat dissipation capacitor cooling fan motor M1 connected in parallel with each other, the compressor motor COMP1 and the heat dissipation capacitor cooling fan motor M1 do not operate. .

그 다음, 마이크로 컴퓨터(MC1)의 제어신호(CNTRL1)가 고전위로 출력되면, 그 마이크로 컴퓨터(MC1)의 제어신호(CNTRL1)를 인버터(INV1)를 통해 인가받은 계전기(RY1)는 온이 된다. 이에 따라 전압 전원(POWER)이 상호 병렬접속된 압축기 모터(COMP1)와 방열콘덴서 냉각팬모터(M1)에 인가되어, 상기 상호 병렬접속된 압축기 모터(COMP1)와 방열콘덴서 냉각팬모터(M1)는 구동된다.Then, when the control signal CNTRL1 of the microcomputer MC1 is output at high potential, the relay RY1 applied to the control signal CNTRL1 of the microcomputer MC1 through the inverter INV1 is turned on. Accordingly, the voltage power POWER is applied to the compressor motor COMP1 and the heat dissipation capacitor cooling fan motor M1 connected in parallel to each other, so that the mutually connected compressor motor COMP1 and the heat dissipation capacitor cooling fan motor M1 are connected to each other. Driven.

그러나, 종래의 방열콘덴서 냉각팬모터는 외부의 온도와 관계없이 압축기 모터가 동작할때는 항상 동작함으로써 불필요한 전력소모가 많고, 소음이 증가하는 문제점이 있었다.However, the conventional heat dissipation capacitor cooling fan motor has a problem that the power consumption is much, and noise is increased by always operating when the compressor motor is operated regardless of the external temperature.

이와 같은 문제점을 감안한 본 발명은 그 방열콘덴서 냉각팬모터의 동작제어를 압축기 모터와 구별하여 동작시키는 냉장고의 방열콘덴서 냉각팬모터 제어회로의 제공에 그 목적이 있다.In view of the above problems, an object of the present invention is to provide a heat dissipation capacitor cooling fan motor control circuit of a refrigerator which operates operation of the heat dissipation capacitor cooling fan motor separately from the compressor motor.

도1은 종래 냉장고의 방열콘덴서 냉각팬모터 제어회로도.1 is a heat radiation capacitor cooling fan motor control circuit diagram of a conventional refrigerator.

도2는 본 발명에 의한 냉장고의 방열콘덴서 냉각팬모터 제어회로도.Figure 2 is a heat radiation capacitor cooling fan motor control circuit of the refrigerator according to the present invention.

It is composed.

이하, 상기와 같은 구성된 본 발명에 의한 냉장고의 방열콘덴서 냉각팬모터 제어회로의 동작을 설명한다.Hereinafter, the operation of the heat dissipation capacitor cooling fan motor control circuit of the refrigerator according to the present invention configured as described above will be described.

먼저, 온도감지센서(TS1)에서 감지된 냉장고의 외부 온도가 설정온도 보다 높은 경우에는 마이크로 컴퓨터(MC1)는 두 제어신호(CNTRL1),(CNTRL2)를 고전위로 하여 출력한다. 상기 고전위의 제어신호(CNTRL1),(CNTRL2)를 인버터(INV1),(IVN2)를 통해 인가받은 두 계전기(RY1),(RY2)는 모두 온이 된다. 이에 따라 전압전원(POWER)은 압축기 모터( COMP1)와 방열콘덴서 냉각팬모터(M1)에 인가되어 압축기 모터(COMP1)와 방열콘덴서 냉각팬모터(M1)를 구동시킨다.First, when the external temperature of the refrigerator detected by the temperature sensor TS1 is higher than the set temperature, the microcomputer MC1 outputs the two control signals CNTRL1 and CNTRL2 at high potential. The two relays RY1 and RY2 that have received the high potential control signals CNTRL1 and CNTRL2 through the inverters INV1 and IVN2 are turned on. Accordingly, the voltage power POWER is applied to the compressor motor COMP1 and the heat dissipation capacitor cooling fan motor M1 to drive the compressor motor COMP1 and the heat dissipation capacitor cooling fan motor M1.

그 다음, 온도감지센서(TS1)에서 감지된 냉장고의 외부 온도가 설정온도 보다 낮은 경우에는 마이크로 컴퓨터(MC1)는 제어신호(CNTRL1)를 고전위로, 제어신호(CNTRL2)를 저전위로 출력한다. 인버터(IVN1)를 통해 상기 고전위의 제어신호(CNTRL1)를 입력받은 계전기(RY1)는 온이되고, 인버터(INV2)를 통해 상기 저전위의 제어신호(CNTRL2)를 입력받은 계전기(RY2)는 오프된다. 이에 따라 전원전압(POWER)은 압축기 모터(COMP1)에만 인가 되어 압축기 모터(COMP1)를 구동시키며, 방열콘덴서 냉각팬모터(M1)는 동작시키지 않게 된다.Next, when the external temperature of the refrigerator detected by the temperature sensor TS1 is lower than the set temperature, the microcomputer MC1 outputs the control signal CNTRL1 at high potential and the control signal CNTRL2 at low potential. The relay RY1 receiving the high potential control signal CNTRL1 through the inverter IVN1 is turned on, and the relay RY2 receiving the low potential control signal CNTRL2 through the inverter INV2 is turned on. Is off. Accordingly, the power supply voltage POWER is applied only to the compressor motor COMP1 to drive the compressor motor COMP1, and the heat dissipation capacitor cooling fan motor M1 is not operated.

상기한 바와 같이 본 발명에 의한 냉장고의 방열콘덴서 냉각팬모터 제어회로는 냉장고 외부의 온도가 설정온도 보다 낮은 경우 방열콘덴서 냉각팬모터를 구동시키지 않음으로써 소비전력을 감소시키며, 소음을 줄이는 효과가 있다.As described above, the heat dissipation capacitor cooling fan motor control circuit of the refrigerator according to the present invention may reduce power consumption and reduce noise by not driving the heat dissipation capacitor cooling fan motor when the temperature outside the refrigerator is lower than the set temperature. .
