본 발명은 팬히터용 솔레노이드밸브의 동작제어방법에 관한 것으로 특히 팬히터 소화시 솔레노이드밸브의 니들샤프트가 휘거나 이물질이 연료공급노즐 주위에 끼어 니들샤프트가 연료공급노즐을 폐쇄하지 못하면 솔레노이드밸브를 2∼3회 구동하여 니들샤프트가 연료공급노즐을 정확히 폐쇄하도록 제어하는 팬히터용 솔레노이드밸브의 동작제어방법에 관한 것이다.The present invention relates to a method for controlling the operation of a solenoid valve for a fan heater. In particular, when a fan heater is extinguished, the needle shaft of the solenoid valve is bent or a foreign material is caught around the fuel supply nozzle so that the needle shaft does not close the fuel supply nozzle. The present invention relates to a method of controlling the operation of a solenoid valve for a fan heater to control the needle shaft so that the needle shaft closes the fuel supply nozzle correctly.

일반적으로, 팬히터는 연료탱크에 저장되어 있는 액체상태의 연료를 기화시킨 후, 이 기화된 연료를 버너로 분사하여 연소시킨다.In general, the fan heater vaporizes liquid fuel stored in the fuel tank, and then injects the vaporized fuel into a burner to burn it.

즉, 제2도에 도시된 것처럼 사용자가 키입력부(10)를 통해 팬히터를 구동시키면 제어부(30)는 전자펌프(40)를 구동하여 연료탱크에 저장되어 있는 연료를 기화기로 공급하여 기화시키고 동시에 솔레노이드밸브(50)를 온(ON)시켜 기화기에서 기화된 연료를 버너로 분사한다.That is, as shown in FIG. 2, when the user drives the fan heater through the key input unit 10, the controller 30 drives the electronic pump 40 to supply and vaporize fuel stored in the fuel tank to the vaporizer. The solenoid valve 50 is turned on to inject the vaporized fuel from the vaporizer to the burner.

한편, 상기와 같이 솔레노이드밸브(50)에 의해 버너로 분사된 연료는 점화트랜스(60)에 의해 점화되고, 염전압 검출부(20)에서 검출된 화염의 염전압이 기준전압 보다 크면 제어부(30)는 점화트랜스(60)를 오프(OFF) 시켜 착화행정을 종료한다.On the other hand, the fuel injected into the burner by the solenoid valve 50 as described above is ignited by the ignition transformer 60, if the salt voltage of the flame detected by the salt voltage detector 20 is greater than the reference voltage control unit 30 Turns off the ignition transformer 60 to end the ignition administration.

제3도는 제2도의 솔레노이드밸브의 동작을 보다 구체적으로 설명하기 위한 도면으로 팬히터가 운전개시되면 솔레노이드밸브(50)는 온(ON)된다. 이에 따라, 솔레노이드밸브(50)에 결합되어 있는 니들샤프트(70)가 후퇴하여 제3도의 (b)와 같이 연료공급노즐(80)을 개방한다. 따라서, 기화기(90)에서 기화된 연료가 개방된 연료분사노즐(80)을 통해 버너로 분사된다.FIG. 3 is a view for explaining the operation of the solenoid valve of FIG. 2 in more detail. When the fan heater starts operation, the solenoid valve 50 is turned on. Accordingly, the needle shaft 70 coupled to the solenoid valve 50 retreats to open the fuel supply nozzle 80 as shown in FIG. Therefore, the fuel vaporized in the vaporizer | carburetor 90 is injected to a burner through the fuel injection nozzle 80 which was opened.

반면, 팬히터의 소화시에는 솔레노이드밸브(50)가 오프(OFF)되어 니들샤프트(70)는 전진한다. 이에따라 니들샤프트(70)가 제3도의 (a)와 같이 연료공급노즐(80)을 폐쇄하여 버너로 분사되는 연료의 공급을 차단한다.On the other hand, when the fan heater is extinguished, the solenoid valve 50 is turned off and the needle shaft 70 is advanced. Accordingly, the needle shaft 70 closes the fuel supply nozzle 80 as shown in FIG. 3A to block supply of fuel injected to the burner.

그러나 상기와 같이 동작하는 솔레노이드밸브의 니들샤프트가 휘거나 이물질이 연료공급노즐 주위에 끼면 니들샤프트가 연료공급노즐을 폐쇄하지 못하게 된다. 따라서, 버너로 공급되는 연료가 공급차단되지 못함에 따라 화재가 발생할 수 있으며 또한 제품의 신뢰성을 저하시킨다는 문제점이 있다.However, when the needle shaft of the solenoid valve operated as described above is bent or foreign matter is caught around the fuel supply nozzle, the needle shaft does not close the fuel supply nozzle. Therefore, there is a problem that a fire may occur as the fuel supplied to the burner is not cut off, and the reliability of the product is lowered.

이에, 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로 팬히터 소화기 솔레노이드밸브의 니들샤프트가 연료공급노즐을 폐쇄하지 못하면 솔레노이드밸브를 2∼3회 구동하여 니들샤프트가 연료공급노즐을 정확히 폐쇄하도록 제어하고, 솔레노이드밸브를 2∼3회 구동하여도 니들샤프트가 연료공급노즐을 폐쇄하지 못하면 에러경보를 발생하여 사용자가 필요한 조치를 취할 수 있도록 하므로써 화재의 발생을 방지할 수 있으며 제품의 신뢰성을 향상시킬수 있는 팬히터용 솔레노이드밸브의 동작제어방법을 제공하는 것을 그 목적으로 한다.Therefore, the present invention was devised to solve the above problems, and if the needle shaft of the fan heater fire extinguisher solenoid valve does not close the fuel supply nozzle, the solenoid valve is driven two or three times so that the needle shaft accurately closes the fuel supply nozzle. If the needle shaft fails to close the fuel supply nozzle even though the solenoid valve is controlled two or three times, an error alarm is generated so that the user can take necessary measures to prevent the occurrence of fire and improve the reliability of the product. It is an object of the present invention to provide a method of controlling the operation of a solenoid valve for a fan heater.

상기와 같은 목적을 달성하기 위하여 본 발명은, 팬히터에 적용되는 솔레노이드밸브 동작제어방법에 있어서, 연소모드 수행중 사용자가 키입력부를 통해 소화명령을 인가하였는지 판단하는 제1 단계와, 상기 제1 단계에서 소화명령이 인가되었으면 전자펌프의 구동을 중지시키고 솔레노이드밸브를 오프(OFF)시켜 버너로의 연료공급을 차단하며 염전압 검출부를 통해 화염이 검출되는지 판단하는 제2 단계와, 상기 제2 단계에서 화염이 검출되면 솔레노이드밸브를 소정횟수 온(ON)/오프(OFF)시켜 버너로의 연료의 공급을 차단하는 제3 단계와, 상기 제3 단계 수행중에 염전압 검출부를 통해 화염이 검출되지 않으면 정상소화동작을 수행하는 제4 단계와, 상기 제3 단계 수행후에도 염전압 검출부를 통해 화염이 검출되면 에러경보를 발생하는 제5 단계를 구비하는 것을 특징으로 한다.In order to achieve the above object, the present invention, in the solenoid valve operation control method applied to the fan heater, the first step of determining whether the user applies a fire extinguishing command through the key input unit during the combustion mode, and the first step In step 2, if the extinguishing command is applied, the operation of the electronic pump is stopped, the solenoid valve is turned off, the fuel supply to the burner is shut off, and the flame is detected through the salt voltage detector. A third step of shutting off the supply of fuel to the burner by turning the solenoid valve on / off a predetermined number of times when the flame is detected; and if the flame is not detected through the salt voltage detector during the third step, A fourth step of performing a fire extinguishing operation and a fifth step of generating an error alarm when a flame is detected through the salt voltage detector even after performing the third step. And that is characterized.

이하, 본 발명의 바람직한 일실시예를 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제1도는 본 발명에 따른 팬히터용 솔레노이드밸브 동작제어방법의 흐름도를 나타낸 것으로 사용자가 연소중에 팬히터를 소화시키기 위해 키입력부(10)를 통해 소화명령을 인가하면 제어부(30)는 연료탱크에 저장되어 있는 연료를 기화기로 공급하는 전자펌프(40)의 구동을 중지시키고 또한 기화기에서 기화된 연료를 버너로 분사하는 솔레노이드밸브(50)를 오프(OFF)시켜 이 솔레노이드밸브(50)에 결합되어 있는 니들샤프트(70)가 연료공급노즐(80)을 폐쇄하도록 제어한다(101 내지 103).1 is a flowchart of a solenoid valve operation control method for a fan heater according to the present invention. When a user applies a extinguishing command through a key input unit 10 to extinguish a fan heater during combustion, the controller 30 is stored in a fuel tank. The needle coupled to the solenoid valve 50 is turned off by turning off the solenoid valve 50 for injecting the fuel to the vaporizer and injecting the vaporized fuel from the vaporizer into the burner. The shaft 70 controls to close the fuel supply nozzle 80 (101 to 103).

상기와 같이 니들샤프트(70)가 연료공급노즐(80)을 폐쇄하도록 제어한 이후 염전압 검출부(20)에 화염의 염전압이 검출되지 않으면 정상소화동작을 수행하고 니들샤프트(70)가 연료공급노즐(80)을 폐쇄하도록 제어한 이후에도 염전압 검출부(20)에 화염의 염전압이 검출되면 제어부(30)는 니들샤프트(70)가 휘거나 연료공급노즐(80) 주위에 이물질이 끼어 니들샤프트(70)가 연료공급노즐(80)을 폐쇄하지 못한 것으로 판단한다. 따라서 제어부(30)는 솔레노이드밸브(50)를 2∼3회 온(ON)/오프(OFF)시켜 니들샤프트(70)가 정확히 연료공급노즐(80)을 폐쇄할 수 있도록 제어한다(104 내지 110).If the salt voltage of the flame is not detected by the salt voltage detector 20 after the needle shaft 70 is controlled to close the fuel supply nozzle 80 as described above, the fire extinguishing operation is performed and the needle shaft 70 supplies fuel. Even after controlling to close the nozzle 80, if the salt voltage of the flame is detected by the salt voltage detector 20, the controller 30 may bend the needle shaft 70 or may trap foreign matter around the fuel supply nozzle 80. It is determined that 70 has not closed the fuel supply nozzle 80. Therefore, the controller 30 controls the needle shaft 70 to close the fuel supply nozzle 80 by turning the solenoid valve 50 on / off two or three times (104 to 110). ).

솔레노이드밸브(50)를 2∼3회 온(ON)/오프(OFF)시키는 동안에 염전압 검출부(20)에 화염의 염전압이 검출되지 않으면 제어부(30)는 니들샤프트(70)가 연료공급노즐(80)을 폐쇄한 것으로 판단하여 정상소화동작을 수행한다(112).If the flame voltage of the flame is not detected by the salt voltage detection unit 20 while the solenoid valve 50 is ON / OFF 2 or 3 times, the control unit 30 controls the needle shaft 70 to supply the fuel supply nozzle. It is determined that 80 is closed to perform a normal fire extinguishing operation (112).

한편, 솔레노이드밸브(50)를 2∼3회 온(ON)/오프(OFF)시켜도 염전압 검출부(20)에 화염의 염전압이 검출되면 제어부(30)는 니들샤프트(70)가 연료공급노즐(80)을 폐쇄하지 못한 것으로 판단하여 사용자가 필요한 조치를 취할 수 있도록 경보를 발생한다(111).On the other hand, even when the solenoid valve 50 is turned on / off 2 or 3 times, if the salt voltage of the flame is detected by the salt voltage detection unit 20, the control unit 30 causes the needle shaft 70 to supply the fuel supply nozzle. It is determined that 80 has not been closed, and an alarm is generated so that the user can take necessary measures (111).

상기와 같이 본 발명은, 팬히터 소화기 솔레노이드밸브의 니들샤프트가 연료공급노즐을 폐쇄하지 못하면 솔레노이드밸브를 2∼3회 구동하여 니들샤프트가 연료공급노즐을 폐쇄하도록 제어하고, 솔레노이드밸브를 2∼3회 구동하여도 니들샤프트가 연료공급노즐을 폐쇄하지 못하면 에러경보를 발생하여 사용자가 필요한 조치를 취할 수 있도록 함에따라 팬히터의 완전연소를 수행할 수 있으며 또한 제품의 신뢰성을 확보할 수 있다.As described above, if the needle shaft of the fan heater fire extinguisher solenoid valve fails to close the fuel supply nozzle, the solenoid valve is operated two to three times to control the needle shaft to close the fuel supply nozzle, and the solenoid valve is operated two to three times. If the needle shaft fails to close the fuel supply nozzle even when it is driven, an error alarm is generated so that the user can take necessary action, so that the fan heater can be completely burned and the reliability of the product can be secured.
