Description

Control method of initial ignition of rotary heater

The present invention relates to a method for controlling the initial ignition of a rotary heater, and in particular, connects a connecting tube which can be opened and closed by a solenoid valve between a burner and a blower of a rotary heater to the carburetor side, thereby allowing air in the carburetor heated by the carburetor heater during initial ignition. The invention relates to a method of controlling initial ignition of a rotary heater in which a blower unit sucks in and supplies this heated air to a burner head to improve the vaporization performance of the fuel during initial ignition and to prevent the generation of unburned gas.

In general, a rotary heater is used to ignite by using electricity and a combustion device that burns using petroleum, and does not need to install an exhaust pipe separately.

4 is a view showing the configuration of the carburetor assembly of the rotary heater used as described above, each of the upper air duct 14 and the lower air duct 16 in which the combustion air rising hole 12 is drilled in the partition 10. And an air duct 18 formed to coincide with the combustion air rising holes 12 of the partition wall 10 and wound integrally with aluminum tape around the outer periphery thereof, and fixed to the center of the partition wall 10. An oil supply pipe 24 is provided having a diffuser 22 interlocked with the diffusion motor 20 and connected to an electron pump to supply fuel to the diffuser 22.

In addition, a vaporizer 28 in which a vaporizer heater H is built around the diffuser 22 and an inlet 26 of combustion air is installed at a lower portion thereof is fixed to the upper air duct 14, and the vaporizer 28 is fixed to the upper air duct 14. The burner head 30 having a salt hole drilled through the outer circumference is mounted on the upper portion of the 28, and the spark plug 32 and the frame rod 34 have a burner plate at a predetermined distance on the flame hole side of the burner head 30. It is fixed to 36).

The lower air duct 16 of the air duct 18 is fixed to one side of the blower 38, which blower 38 has an air inlet 40 and an air outlet 42 and a blower motor. A blower fan 46 interlocked with the 44 is provided.

In the conventional rotary heater configured as described above, when the user turns on the operation switch of the operation panel of the rotary heater, the vaporizer heater H of the vaporizer 28 is energized to heat the vaporizer 28. As the temperature of the vaporizer 28 reaches a certain temperature, the blower motor 44 and the diffusion motor 20 are driven, and at this time, the fuel tank is connected to the diffuser 22 rotating on the diffusion motor 20. The stored liquid fuel is supplied to the diffuser 22 via an oil supply pipe 24 by an electronic pump.

Therefore, since the diffuser 22 is rotated at high speed by the diffusion motor 20, the liquid fuel supplied to the diffuser 22 is instantaneously atomized and discharged into the salt holes of the burner head 30, and at the same time burner plate ( The combustion is ignited by the electric spark generated by the spark plug 32 fixed to 36).

However, when the initial ignition is performed in order to use the rotary heater as described above, the vaporizer heater H is energized to heat the vaporizer 28, and by this heating, the temperature of the vaporizer 28 reaches a predetermined temperature. At the same time, the blower motor 44 and the diffusion motor 20 are driven to perform initial ignition. However, even when the carburetor 28 is sufficiently preheated during the initial ignition, external air supplied for combustion is supplied in a cold state so that the burner head ( In the case of the initial ignition at 30), the mixture with the atomized fuel is not well formed, so that the vaporization performance is reduced, and the indoor air is contaminated by the generation of unburned gas.

The present invention is to solve the above problems, by connecting the connecting tube that can be opened and closed by the solenoid valve between the burner and the blower of the rotary heater to the carburetor side during the initial ignition blower air in the carburetor heated by the carburetor heater It is an object of the present invention to provide a method for controlling the initial ignition of a rotary heater by sucking and supplying the heated air to the burner head to improve the vaporization performance during initial ignition and to prevent the diffusion of unburned gas indoors.

According to the present invention, in the initial ignition control method of the rotary heater, when the user turns on the operation switch of the rotary heater, the control unit turns on the carburetor heater to preheat the carburetor and determines whether the temperature of the carburetor reaches a preset set temperature. In the first step, if the temperature of the carburetor is a set temperature, the control unit turns on the solenoid valve to open the connection pipe, and then drives the blower motor to suck the heated air in the carburetor and supply it to the burner head. In the second step, when the blower motor is driven and the electronic pump is driven to supply fuel, the supplied fuel is atomized from the vaporizer by the diffusion motor and discharged into the flame hole of the burner head. The controller determines whether the ignition has been performed by driving the spark plug, and in the third step, If the ignition is ignited by the operation of the spark plug, the control unit is characterized in that it comprises a fourth step of maintaining the normal combustion of the outside air introduced through the air inlet hole of the blower by closing the connection pipe by turning off the solenoid valve .
