본 고안은 환풍기 장치에 관한 것으로서, 특히 환풍기 운전 시간과 환풍기 정지시간을 설정할수 있는 환풍기용 자동 운전 장치에 관한 것이다.The present invention relates to a fan apparatus, and more particularly, to an automatic driving apparatus for the fan that can set the fan operation time and the fan stop time.

종래에는 제3도에 도시된 바와같이 환풍기 모터(31)의 자체온도 감지용 열계전기(32)와 과전압 배선차단기(33) 및 계전기(34) 그리고 전자 접촉기(35)로 구성되며, 시동버튼(36)을 누르면 계전기(34)가 여자되어 계전기(34)의 접점(34')이 도통되어 계전기(34)가 자려되어서 전자접촉기(35)가 작동되므로 접점(35')이 도통된다.Conventionally, as shown in FIG. 3, the thermostat 32 for self-temperature sensing of the fan motor 31, the overvoltage circuit breaker 33, the relay 34, and the magnetic contactor 35 are provided. When 36 is pressed, the relay 34 is excited to conduct the contact 34 'of the relay 34 so that the relay 34 is open and the magnetic contactor 35 is operated so that the contact 35' is conducted.

이에 따라 환풍기 모터(31)에 전원이 인가되어 환풍기가 운전되는 것이고, 환풍기 모터(31)가 과열되면 열계전기(32)가 작동되어서 접점(32')이 오프되므로 전자 접촉기(35)의 전원을 차단시켜 전자 접촉기(35')의 접점(35')이 오프되므로 환풍기모터(31)의 전원이 차단되어서, 환풍기 운전이 정지되나, 계전기(34)는 여자 상태를 연속 유지하게 되고, 환풍기 모터(31)의 열이 식으면 다시 열계전기(32)의 접점(32')이 도통되고 전자접촉기(35)에 전원이 인가되어 접점(35')이 도통되어 환풍기 모터(31)가 운전되는 것이며, 차단시에는 정지버튼(37)을 누르면 계전기(34)가 소자되어 전자접촉기(35)가 비작동되어 접점(35')이 개방되어 환풍기 모터(31)의 운전이 정지 되는 것이나, 이러한 종래의 환풍기 장치는 사용자가 일일이 손으로 온,오프를 시켜야 하는 것이어서 그 사용이 매우 불편할 뿐 아니라, 환풍기 관리자 이외의 사람은 이러한 작동방법을 잘 모르게 되어 환풍기를 필요없이 연속 구동시키게 되어 전력낭비가 발생되는 단점이 있다.Accordingly, power is supplied to the fan motor 31 to operate the fan. When the fan motor 31 is overheated, the thermal relay 32 is operated to turn off the contact point 32 ', thereby turning off the power of the magnetic contactor 35. Since the contact 35 'of the electromagnetic contactor 35' is turned off, the power of the fan motor 31 is cut off, so that the fan operation is stopped, but the relay 34 continuously maintains the excited state, and the fan motor ( When the heat of 31) cools down, the contact 32 'of the thermal relay 32 is turned on again, the power is applied to the magnetic contactor 35, and the contact 35' is turned on to operate the fan motor 31. When the stop button 37 is pressed, the relay 34 is deactivated, the magnetic contactor 35 is deactivated, the contact 35 'is opened, and the operation of the fan motor 31 is stopped. The device has to be turned on and off manually by the user. Not only inconvenient, someone other than the ventilator manager is knowing how well this works is thereby driven continuously without needing a ventilator has the disadvantage that the power dissipation occurs.

본 고안은 이러한 종래의 단점을 해결하도록 2개의 타이머를 종래의 환풍기 장치에 설치하며, 하나의 타이머로는 환풍기 운전시간을 설정하도록 하고, 나머지 하나의 타이머에는 환풍기 정지시간을 설정하도록 하므로서, 자동으로 환풍기 운전을 제어하여, 필요없는 전력 낭비를 절감하여, 그 사용이 매우 간편한 환풍기용 자동운전장치를 제공하는 것을 목적으로 하며, 이하 첨부된 도면을 참조하면서 본 고안의 구성, 작용효과를 설명하면 다음과 같다.The present invention is to install two timers in the conventional fan device to solve the above disadvantages, one timer to set the operation time of the fan, the other timer to set the fan stop time, automatically It is an object of the present invention to control the operation of the fan, to reduce unnecessary waste of power, and to provide an automatic operation device for the fan, which is very easy to use. Same as

제1도를 참조하면 본 고안 장치의 구성은 과전압배선차단기(1), 전자접촉기(2), 열계전기(3), 모터(4) 및 계전기(5)로 구성된 환풍기 장치에 있어, 계전기(5)의 접점(5')과 전자접촉기(2)의 사이에 제2계전기(6)의 상지 폐쇄접점(6') 및 열계전기(3)의 접점(3')을 직결하고, 접점(3')과 전자 접촉기(2)에 제1타이머(7)를 병렬접속하며, 제1타이머(7)의 접점(7')과 제2타이머(8)의 접점(8') 및 제2계전기(6)의 직렬접속에 제2계전기(6)의 상시 개방접점(6")과 제2타이머(8)의 직렬접속을 병렬로 연결하되, 접점(7')와 상시 개방접점(6")을 병렬 접속하여된 것으로서, 이러한 본 고안 장치의 작용효과를 제2a도-제2f도를 참조하여 설명하면, 우선 시동스위치(10)를 누르면 계전기(5)가 작동되어 접점(5')이 온되어 계전기(5)는 자려된다. 동시에 접점(5')을 통하여 제1타이머(7)와 전자접촉기(2)에 전원이 공급되므로 전자 접촉기(2)의 접점(2')이 도통되어 모터(4)가 구동되어서 환풍기가 운전된다. 또한 제1타이머(7)에 전원이 공급되므로 제1타이머(7)가 동작하기 시작하므로 제1타이머(7)에 세트된 시간(t1)후에는 제1타이머(7)의 접점(7')이 도통되어 제2계전기(6)와 제2타이머(8)에 전원이 공급되므로 제2계전기(6)의 상기 개방접점(6")이 온되어 제2계전기(6)가 자려됨과 동시에 제2계전기(6)의 상시폐쇄접점(6')가 오프되므로 제1타이머(7)와 전자접촉기(2)의 전원 공급이 차단되고 이에 따라서 전자접촉기(2)의 접점(2')이 개방되어 모터(4)의 운전이 정지되는 것이다. 제2타이머(8)에 세트된 시간(t2)후에는 제2타이머(8)의 접점(8')이 개방되어서 제2계전기(6)가 소자되므로 상시 폐쇄접점(6')은 도통되고 상기 개방접점(6")은 개방되어 제2계전기(6)와 제2타이머(8)에 공급되는 전원을 차단함과 동시에 제1타이머(7)와 전자접촉기(2)에 전원을 공급하게 되므로 제1타이머(7)가 작동되기 시작함과 동시에 전자접촉기(2)의 접점(2')이 도통되어서 모터(4)가 운전되기 시작하는 것이므로, 환풍기 운전이 되는 것이다. 이러한 과정을 연속 반복하게 되므로 환풍기 운전이 자동으로 제어 될 수 있는 것이다.Referring to FIG. 1, the device of the present invention is configured of an overvoltage circuit breaker 1, a magnetic contactor 2, a thermal relay 3, a motor 4 and a relay 5, and a relay 5, Between the upper contact closed contact 6 'of the second relay 6 and the contact 3' of the thermal relay 3 between the contact 5 'and the magnetic contactor 2 of ), The first timer 7 is connected in parallel to the electromagnetic contactor 2, and the contact 7 ′ of the first timer 7 and the contact 8 ′ of the second timer 8 and the second relay 6 are connected to each other. ) Is connected in series between the normally open contact 6 "of the second relay 6 and the serial connection of the second timer 8 in parallel, and the contact 7 'and the normally open contact 6" are connected in parallel. As described above, the effects of the device of the present invention will be described with reference to FIGS. 2A to 2F. First, when the start switch 10 is pressed, the relay 5 is operated to turn on the contact 5 '. (5) is to sleep. At the same time, since power is supplied to the first timer 7 and the magnetic contactor 2 through the contact 5 ', the contact 2' of the magnetic contactor 2 is conducted so that the motor 4 is driven to operate the fan. . In addition, since power is supplied to the first timer 7, the first timer 7 starts to operate. Therefore, after the time t 1 set in the first timer 7, the contact point 7 'of the first timer 7 is opened. ) Is turned on so that power is supplied to the second relay 6 and the second timer 8 so that the open contact 6 "of the second relay 6 is turned on so that the second relay 6 is brought out and Since the normally closed contact point 6 'of the relay 6 is turned off, the power supply of the first timer 7 and the magnetic contactor 2 is cut off and thus the contact 2' of the magnetic contactor 2 is opened. The operation of the motor 4 is stopped.After the time t 2 set in the second timer 8, the contact 8 'of the second timer 8 is opened so that the second relay 6 becomes an element. Therefore, the normally closed contact 6 'is turned on and the open contact 6 "is opened to cut off the power supplied to the second relay 6 and the second timer 8 and at the same time the first timer 7 Since the power is supplied to the magnetic contactor 2, the first stroke As the immer 7 starts to operate and the contact 2 'of the magnetic contactor 2 becomes conductive, the motor 4 starts to operate, and thus, the fan operation is performed. Since this process is repeated repeatedly, the operation of the fan can be controlled automatically.

그러므로 제1타이머(7)에 세트된 시간(t1)은 제2d도에 높은 전위로 도시된 바와 같이 환풍기의 운전시간이 되는 것이고, 제2타이머(8)에 세트된 시간(t2)는 제2e도에 도시된 바와 같이 환풍기 운전 정지 시간이 되는 것이어서 결국 제2f도에 도시된 바와 같이 전자접촉기(2)의 구동시간을 결정하게 되는 것이다.Therefore, the time t 1 set in the first timer 7 becomes the operating time of the fan as shown at a high potential in FIG. 2d, and the time t 2 set in the second timer 8 is As shown in FIG. 2E, the operation time of the fan is stopped, and thus the driving time of the magnetic contactor 2 is determined as shown in FIG. 2F.

제2b도, 제2c도는 계전기(5)와 제2계전기(6)의 동작상태를 도시한 것이다.2B and 2C show the operating states of the relay 5 and the second relay 6.

이상에서 설명된 바와 같이 본 고안에 의하면 환풍기 운전을 일일이 조작자가 하지 않더라도 한번만 타이머를 세팅하여 놓으면 자동적으로 운전제어 되므로 그 사용이 매우 간편한 것이고 장시간 모터 구동에 의한 환풍기 소손의 위험을 제거함과 동시에 불필요한 전력 낭비를 방지할수 있는 것이다.As described above, according to the present invention, even if the operator does not operate the fan at once, the operation is automatically controlled when the timer is set only once, and its use is very easy. You can prevent waste.
