The present invention relates to a method for controlling an electric pump driving of an oil combustor. In particular, a reed switch is mounted on a predetermined portion of an oil combustor oil supply pipe to detect the presence of oil in the oil supply pipe, and oil in the oil supply pipe is not detected while the electronic pump is being driven. If not, the present invention relates to a method for controlling an electric pump driving of an oil burner using a reed switch that stops driving of the electronic pump and prevents malfunction and malfunction due to overload of the electronic pump.

In general, the oil stored in the fuel tank of the oil burner is supplied to the carburetor through the oil pipe in accordance with the operation of the electronic pump.

However, when the operation of the electronic pump is poor, for example, even if foreign matter is stuck in the electronic pump and the operation is impossible, the electronic pump continuously tries to operate, causing the electronic pump to be overloaded, resulting in damage or malfunction of the electronic pump. I may cause it.

Accordingly, the present invention has been made in order to solve the above problems, by mounting a reed switch in a predetermined portion of the oil combustor oil supply pipe to detect the presence of oil in the oil supply pipe, the oil in the oil supply pipe is detected while the electronic pump is running If not, the object of the present invention is to provide an electronic pump driving control method for an oil combustor using a reed switch that stops the operation of the electronic pump to prevent failure and malfunction due to an overload of the electronic pump.

In order to achieve the above object, the present invention, in the electronic pump drive control method applied to the oil burner having a reed switch for detecting the presence or absence of oil in the oil burner oil pipeline, by driving the carburetor preheating heater A first step of preheating the carburetor, a second step of measuring the temperature of the carburetor preheated in the first step and comparing it with a preset reference temperature, and if the temperature of the carburetor measured in the second step is higher than the reference temperature A third step of sequentially driving the motor, the ignition transformer, and the electronic pump; a fourth step of detecting a switching state of the reed switch when the blower motor, the ignition transformer, and the electronic pump are driven in the third step; And a fifth step of stopping the driving of the electronic pump and generating an alarm if the reed switch is turned off in step 4. It is done.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows the configuration of the oil burner to which the present invention is applied, the power switch 10 for controlling the operation of the oil burner and the carburetor preheating preheating the carburetor by applying power according to the operation of the power switch 10 A heater 70 and a vaporizer thermistor 20 for detecting the temperature of the vaporizer preheated by the vaporizer preheater 70 are provided.

In addition, the oil burner is an electronic pump (80) for supplying the oil stored in the fuel tank to the vaporizer, an ignition transformer (40) for igniting the oil supplied by the electronic pump (80), the oil to the vaporizer A blower motor 60 for supplying primary air required for combustion of the fuel, a reed switch 30 mounted on a predetermined portion of the oil burner oil pipe, and detecting the presence of oil in the oil pipe, and operation of the reed switch 30 The control unit 50 for controlling the operation of the electronic pump 80 and the alarm unit 90 for generating an alarm when the reed switch 30 is turned off while the electronic pump 80 is being driven. Equipped.

On the other hand, the reed switch 30 may be mounted in the oil pipe in a swing plate method or a float method, Figure 2 (a) shows a swing plate-type reed switch, Figure 2 (b) is a float-type lead The figure which shows a switch.

As shown in (a) of FIG. 2, the swing plate method includes a plate 31 having a reed switch 30 mounted at a predetermined portion of an oil supply pipe 100 and a permanent magnet 33 fixedly mounted at a lower portion thereof. Is rotatably mounted by hinge 32. Therefore, when oil flows in the oil feed pipe 100 in the direction of the arrow by the electromagnetic pump 80, the plate 31 rotates upwardly around the hinge to turn on the reed switch 30.

On the other hand, in the float method, as shown in (b) of FIG. 2, the reed switch 30 is mounted at a predetermined portion of the oil oil supply pipe 100, and the float having a permanent magnet 35 fixedly mounted thereon ( 34) is mounted to flow up and down according to the flow of oil. Therefore, when oil flows in the oil pipe 100 in the direction of the arrow by the electromagnetic pump 80, the float 34 floats upward to turn on the reed switch 30.

3 shows a flowchart of an electronic pump driving control method according to the present invention applied to an oil burner having the above configuration.

When the user turns on the power switch 10 to drive the oil burner, the controller 50 applies power to the carburetor preheating heater 70 to preheat the carburetor so that the oil supplied from the fuel tank is easily vaporized. (301, 302).

Meanwhile, the vaporizer thermistor 20 measures the temperature of the vaporizer preheated by the vaporizer preheater 70 and applies it to the controller 50. Accordingly, the controller 50 compares the temperature of the vaporizer measured by the vaporizer thermistor 20 with a preset reference temperature (303).

If the temperature of the carburetor measured by the carburetor thermistor 20 is lower than the preset reference temperature, the controller 50 may allow the carburetor preheating heater 70 to preheat the carburetor until the measured carburetor temperature reaches the preset reference temperature. To control.

On the other hand, if the temperature of the carburetor measured by the carburetor thermistor 20 is higher than the predetermined reference temperature, the controller 50 drives the blower motor 60 for supplying the primary air required for the combustion of oil to the carburetor (304).

When the blower motor 60 is driven, the controller 50 sequentially supplies the ignition transformer 40 for igniting the oil supplied from the fuel tank to the vaporizer, and the electronic pump 80 for supplying the oil stored in the oil tank to the vaporizer. After driving, the switching state of the reed switch 30 is detected (305 to 307).

If the reed switch 30 is ON, the control unit 50 performs the combustion mode as the electronic pump 80 is normally driven (311).

On the other hand, if the reed switch 30 is OFF (OFF), the control unit 50 determines that the electronic pump 80 is not operating normally, stops the operation of the electronic pump 80, performs a fire-extinguishing mode and alarms It generates and informs the user of the abnormal operation of the electronic pump 80 (308 to 310).

As described above, the present invention detects the presence or absence of oil in the oil supply pipe through a reed switch mounted in the oil burner oil supply pipe, and stops the operation of the electronic pump if the oil in the oil supply pipe is not detected while the electronic pump is in operation. It can prevent failure and malfunction due to overload.

In addition, the present invention can secure the safety and reliability of the product by generating an alarm sound so that the user can take the necessary measures in the abnormal operation of the electronic pump.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. Therefore, the true technical protection scope of the present invention should be defined only by the appended claims.
