本考案は予熱を必要とする液体燃焼器具の燃焼

向上させることにある。[Detailed description of the invention] This invention relates to a combustion control device for liquid combustion appliances that require preheating, and its purpose is to effectively utilize positive temperature coefficient thermistors, heaters, lamps, switches, etc. The purpose is to improve the operability and usability of the system.

じ時間かかつており、使い勝手の悪いものであつ
た。 Generally speaking, in combustion appliances that require preheating, the temperature in the vaporizing chamber rises and reaches the predetermined vaporizing temperature after the power switch is operated, but there is no way to display this, and the user has to rely on the user to reach the vaporizing temperature. I knew what I had done. In addition, the time it takes to reach this vaporization temperature cannot be changed, and the user can ignite it directly (to shorten the time it takes to reach the vaporization temperature) or use an ignition timer (to reach the vaporization temperature). There were times when it was okay to wait for a long time), and it was not easy to use.
本考案は、このような従来の欠点を一掃したも

ある。 In the figure, 1 is a power switch, and 2 is a thermoswitch installed on the outer wall of the vaporization chamber, which opens when the temperature exceeds a set temperature. 3 is a heater for preheating the vaporizing chamber connected in series with the thermoswitch 2, and 4 is a relay coil having a normally closed relay contact 4a. Reference numeral 5 denotes a positive temperature coefficient thermistor for preheating the vaporization chamber, which is connected in parallel to the heater 3. 6 is a power indicator lamp, 7 is an ignition switch, 8 is a fan for blowing hot air, 9 is a combustion fan, 10 is a high-voltage ignition transformer, 11 is a power transformer, 12 is a combustion detection circuit, 13 is a combustion detection circuit. With the working relay coil, both the blowers 8,
9. It has a normally closed relay contact 13a connected in series with the ignition transformer 10. 14 is a temperature switch for preventing abnormal overheating, and 15 is a preheating speed changeover switch such as a toggle switch, which are connected in series with the heater 3. A neon lamp 16 is also connected in parallel with the thermoswitch 2, and is connected in series with the relay coil 4. Note that 17 in the figure is an oil pump.

に維持する。 In the above configuration, when the power switch 1 is turned on, the relay coil 4 is energized via the thermoswitch 2 with low resistance, and the normally closed relay contact 4
a opens. At the same time, the positive temperature coefficient thermistor 5 for preheating the vaporization chamber 5 also starts to be energized, and preheating begins. At this time, if the preheating speed selector switch 15 is closed, the heater 3 and the positive temperature coefficient thermistor 5 are closed.
energization is also started, making it possible to shorten the preheating time. On the other hand, when there is no need to shorten the waiting time for preheating, such as when automatic ignition is performed using an ignition time switch, the preheating speed changeover switch 15 is left open. Thereby, preheating can be performed only by the positive temperature coefficient thermistor 5, and power consumption can be reduced. Next, when the vaporization chamber temperature reaches a predetermined temperature, the thermoswitch 2 is opened and the energization to the relay coil 4 is stopped. Thereafter, the self-temperature control characteristic of the positive temperature coefficient thermistor 5 maintains the vaporization chamber at a predetermined temperature.

し、瞬時に運転を停止させる。 When the thermo switch 2 is opened, the neon lamp 16 lights up at the same time to indicate that preheating is complete. Then, the relay coil 4 becomes de-energized again, the relay contact 4a closes, and the convection blower 8,
Electricity is started to flow to the combustion blower 9, high-pressure ignition transformer 10, and oil pump 17, and the vaporized fuel instantaneously ignites in the vaporization chamber whose temperature has risen to a predetermined temperature, starting normal combustion. Then, the combustion detection circuit 12 detects the normal ignition and keeps the normally closed relay contact 13a closed. If there is an ignition error or misfire, the relay coil 13 is energized, its relay contact 13a is opened, and the energization to the convection blower 8, combustion blower 9, high-pressure ignition transformer 10, and oil pump 17 is stopped. Stops operation instantly.

It is also possible to inform the user of the status of the device by displaying it on a display means such as the above, and it is possible to improve both operability and usability.
