Description
본 고안은 방열 팬모터를 구비한 제품의 팬모터 제어회로에 관한 것이며, 보다 상세히는 주위의 온도에 따라 팬모터의 속도를 제어할 수 있는 팬모터 제어회로에 관한 것이다.The present invention relates to a fan motor control circuit of a product having a heat radiating fan motor, and more particularly to a fan motor control circuit that can control the speed of the fan motor according to the ambient temperature.
종래의 팬모터는 카오디오, 컴퓨터 등의 전자 제품에 내장되어 기기 내부열을 외부로 방출시키기 위하여 구비되어 있으나, 기기 내부 온도에 관계없이 제품 동작과 동시에 팬모터가 구동되어 팬이 작용하도록 되어 있어, 방열 팬이 작동되지 않아도 되는 상황에서도 작동되어 불필요한 전류가 소모될 뿐만아니라 방열 핀 및 관련 부품들의 수명이 단축되는 원인이 되었다.Conventional fan motors are built in electronic products such as car audio, computers, etc., and are provided to radiate the internal heat of the device to the outside, but the fan motor is driven to operate the fan simultaneously with the product operation regardless of the internal temperature of the device. It also works in situations where the heat dissipation fan does not need to be used, causing unnecessary current consumption and shortening the life of the heat dissipation fins and related components.
따라서, 본 고안은 상술한 종래의 문제점을 극복하기 위한 것으로서, 본 고안의 목적은 팬내부에 온도 센서 및 팬모터 제어용 마이콤을 내장시켜 제품에 영향을 주는 일정 온도 이상에서만 방열 팬모터가 자동적으로 동작하고, 온도가 떨어지면 자동적으로 멈추도록 하여 전류의 소모를 방지하고 이것에 의해 팬의 수명을 연장시키는 팬모터 제어회로를 제공하는데 있다.Therefore, the present invention is to overcome the above-mentioned conventional problems, an object of the present invention is to incorporate a temperature sensor and a fan motor control microcomputer inside the fan to operate the heat radiating fan motor only at a certain temperature or more affecting the product automatically. The present invention provides a fan motor control circuit that automatically stops when the temperature drops, thereby preventing current consumption and thereby extending the life of the fan.
상기 본 고안의 목적을 달성하기 위한 팬모터 제어회로의 일예로서, 제품내부의 온도를 감지하는 감지부와, 미리 설정된 온도 데이터와 상기 감지부에서 감지된 온도에 비교하는 마이콤과, 상기 마이콤의 출력 제어 신호에 의해 팬모터의 속도를 제어하는 제어부로 구성된다.As an example of a fan motor control circuit for achieving the object of the present invention, a sensing unit for sensing the temperature inside the product, a micom comparing the temperature detected by the preset temperature data and the sensing unit, the output of the micom Control unit for controlling the speed of the fan motor by the control signal.
이러한 구성에 의해, 감지부에서 감지한 온도에 따라 팬모터가 자동적으로 제어된다.With this configuration, the fan motor is automatically controlled according to the temperature detected by the detection unit.

이하, 본 고안의 실시예를 도 1 및 도 2 를 참조하여 상세히 설명하기로 한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2.
도 1 을 참조하면, 본 고안에 따른 팬모터 제어회로는 제품 내부의 온도를 감지하는 감지부(1)와, 미리 설정된 온도 데이터와 상기 감지부(1)에서 감지된 온도를 비교하는 마이콤(2)과, 상기 마이콤(2)의 출력 제어 신호에 의해 팬모터(4)의 속도를 제어하는 제어부(3)로 구성된다.Referring to FIG. 1, a fan motor control circuit according to the present invention includes a sensing unit 1 for sensing a temperature inside a product, and a micom 2 for comparing preset temperature data with a temperature sensed by the sensing unit 1. ) And a controller 3 for controlling the speed of the fan motor 4 by the output control signal of the microcomputer 2.
상기 감지부(1)는 온도 센서로 이루어진다.The detector 1 is made of a temperature sensor.
상기 제어부(3)는 마이콤(2)의 출력 단자에 그 베이스가 접속된 트랜지스터(Q2)와, 상기 트랜지스터(Q2)의 콜렉터에 베이스가 접속된 트랜지스터(Q1)를 포함한다.The control unit 3 includes a transistor Q2 whose base is connected to the output terminal of the microcomputer 2 and a transistor Q1 whose base is connected to the collector of the transistor Q2.
상기와 같은 구성에 의해 본 고안의 팬모터 제어회로는 다음과 같이 작동한다.By the above configuration, the fan motor control circuit of the present invention operates as follows.
감지부(1)에 전원(Vcc)이 공급되면(101), 감지부(1)에서는 제품 또는 기기 내부의 온도를 측정한다(102). 마이콤(2)에서는 미리 설정된 설정 온도와 감지부(1)에서 감지한 온도를 비교한다(103). 비교 결과, 설정 온도이상이면(104), 마이콤(2)은 하이 신호를 출력하여 트랜지스터(Q1, Q2)가 턴온되어(105), 팬모터(4)에 전원이 공급되어 팬모터가 작동한다(106).When the power supply Vcc is supplied to the detection unit 1 (101), the detection unit 1 measures the temperature inside the product or the device (102). In the microcomputer 2, the preset temperature is compared with the temperature detected by the detector 1 (103). As a result of the comparison, when the temperature is higher than the set temperature (104), the microcomputer 2 outputs a high signal so that the transistors Q1 and Q2 are turned on 105, and the fan motor 4 is supplied with power to operate the fan motor ( 106).
비교 결과, 설정 온도이하이면(104), 마이콤(2)은 로우 신호를 출력하여 트랜지스터(Q1, Q2)가 턴오프되어(107), 팬모터(4)로의 전원을 차단하여 팬모터가 정지한다(108).As a result of the comparison, when the temperature is lower than the set temperature (104), the microcomputer 2 outputs a low signal so that the transistors Q1 and Q2 are turned off (107), the power supply to the fan motor 4 is cut off, and the fan motor is stopped. (108).
상술한 바와 같이 본 고안에 따른 팬모터 제어회로는 온도 센서를 이용하여 기기 내부의 온도에 따라 팬모터의 구동을 달리하여 전류의 소비를 막고, 팬의 수명을 연장시키게 된다.As described above, the fan motor control circuit according to the present invention uses a temperature sensor to prevent the consumption of current by varying the driving of the fan motor according to the temperature inside the device, thereby extending the life of the fan.
이상에서 설명한 것은 본 고안에 따른 팬모터 제어회로를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 고안은 상기한 실시예에 한정되지 않고, 이하의 실용신안등록청구의 범위에서 청구하는 본 고안의 요지를 벗어남이 없이 당해 고안이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변경 실시가 가능할 것이다.What has been described above is just one embodiment for implementing the fan motor control circuit according to the present invention, the present invention is not limited to the above-described embodiment, the present invention claimed in the following utility model registration claims Various modifications can be made by those skilled in the art without departing from the gist of the present invention.
