The illumination confirmation circuit 13 includes an illumination detection unit 4
A timer start signal is output to the time counting means 10 by the illumination detection signal from the timer. If the illumination detection signal is output from the illumination detection means 4 when the timer end signal is output from the time counting means 10, an illumination confirmation signal is output. Is what you do. The mode setting storage circuit 14 stores the setting of the illumination preheating start mode by turning on the lighting preheating start mode button 7 of the operation unit 5, and sets the setting of the lighting preheating start mode by turning on the operation button 6 of the operation unit 5. This is to erase the memory. When the illumination confirmation signal is output from the illumination confirmation circuit 13, the time zone comparison circuit 15
And confirms whether the setting of the lighting preheating start mode is stored in the timer unit 11. When the setting is stored, a time confirmation signal is output to the clock unit 11 so that the current time output from the clock unit 11 and the predetermined time period are output. Is to be compared with

The night check output circuit 16 outputs a night check signal when the time of the clock section 11 is within a predetermined time zone as a result of the comparison by the time zone comparison circuit 15. The notification sound generation circuit 17 outputs a notification sound generation signal to the notification means 10 based on a notification signal from the combustion control circuit 20 to generate a notification sound. The temperature comparison circuit 18 compares the temperature of the vaporizing section of the combustion section 1 detected by the temperature detecting means 2 with a predetermined optimal vaporizing temperature. The heater energization circuit 19 energizes the heater 3 embedded in the vaporization section of the combustion section 1.

When the lighting preheating start mode is not set, the combustion control circuit 20 operates the operation button 6 of the operation unit 5.
Is turned on, the temperature detection circuit 2
The temperature of the vaporizing section of the combustion section 1 detected in the above is compared with a predetermined optimum vaporization temperature. When the temperature of the vaporization section of the combustion section 1 is lower than the predetermined optimum vaporization temperature, the heater energizing circuit 19
Is operated to energize the heater 3 to preheat the vaporizing section of the combustion section 1. When the temperature of the vaporizing section of the combustion section 1 becomes equal to or higher than a predetermined optimum vaporization temperature, the operation of the heater energizing circuit 19 is stopped and the heater 3 is turned off. A preheating operation for stopping the power supply to the combustion unit is performed, and the electromagnetic pump and the combustion fan are operated to send the liquid fuel and the combustion air to the vaporization unit of the combustion unit 1 to generate an air-fuel mixture, which is ignited by ignition means.

When the lighting preheating start mode is set, the combustion control circuit 20 outputs the nighttime confirmation output circuit 1
When the night confirmation signal is output from 6, the preheating operation of the vaporizing section of the combustion section 1 is performed, and when the preheating operation is completed, a notification signal is output to the notification sound generation circuit 17 and the notification sound generation circuit 17 causes the notification means 9 to output the notification signal. Operate to generate a notification sound. Then, after the notification sound is generated, if the operation button 6 is not turned on, the notification sound is generated a predetermined number of times. If the operation button 6 is turned on, the combustion start operation is performed. The operation of the illumination preheating start mode is stopped.

Next, the operation of this embodiment will be described. In the morning, before going out, the user operates the lighting preheating start button 7 to set the lighting preheating start mode. When the user returns home at night and turns on the room lighting, the lighting detecting means 4 first detects the light of the lighting. And outputs an illumination detection signal to the illumination confirmation circuit 13. (S12) When the illumination detection signal from the illumination detection unit 4 is input, the illumination confirmation circuit 13 outputs a timer start signal to the timer unit 10.
In the present embodiment, timing for 5 seconds is started. This is to prevent the lighting preheating start mode from being operated erroneously when the lighting is turned on for a short time, that is, when the user returns to the room but goes out again immediately.

When a predetermined time T elapses, the time counting means 1
0 outputs a timer end signal to the illumination confirmation circuit 13. When the timer end signal is output from the timer 10, the illumination confirmation circuit 13 confirms whether an illumination detection signal is output from the illumination detection unit 4 and When the detection signal has been output, it is determined that the user has returned home, and an illumination confirmation signal is output. When the illumination detection signal has not been output, it is determined that the user has not returned home, and the illumination detecting means 5 emits the light of the illumination. Return to the state before detection. (S13)

In response to the illumination confirmation signal from the illumination confirmation circuit 13, the time zone comparison circuit 15 causes the mode setting storage circuit 1
It is confirmed whether or not the setting of the lighting preheating start mode is stored in Step 4 (S14). If it is confirmed that the setting of the lighting preheating start mode is stored, a time confirmation signal is output to the clock unit 11, and the time is output. In response to the confirmation signal, the clock unit 11 outputs the time at that time to the time zone comparison circuit 15 using a signal. Then, the time zone comparison circuit 15 compares the time at that time based on the signal output from the clock unit 11 with a time zone predetermined as nighttime. (S15)

As a result of the comparison by the time zone comparison circuit 15,
When the time from the clock section 11 is within a predetermined time zone of night, it is determined that the illumination preheating start mode may be executed at night, and the night confirmation output circuit 16 outputs a night confirmation signal. In this embodiment, the use time is set to winter and 6 pm
The period from time to 5:00 am is set as nighttime, because the illumination preheating start mode is operated at night without natural light, and the illumination detection means 4 erroneously detects daytime sunlight as illumination light. This prevents the lighting preheating start mode from being erroneously executed.

The combustion control circuit 20 outputs the night-time confirmation signal from the night-time confirmation output circuit 16 so that the temperature comparison circuit 1
8 shows the temperature of the vaporizing section in the combustion section 1 detected by the temperature detecting means 2 and the preset optimal vaporizing temperature, that is, the temperature x ° C. at which the liquid fuel is successfully vaporized and mixed with the combustion air to smoothly burn. (S16), and when the detected temperature is lower than x ° C., the heater 3 is energized by the heater energizing circuit 19 to increase the temperature of the vaporizing section (S17). When the detected temperature is higher than x ° C., the heater is energized. The power supply to the heater 3 by the circuit 19 is stopped, and the notification sound generation circuit 1 is turned off.
A notification signal is output to the notification signal generator 7 and the notification means 9 is operated by the notification sound generation circuit 17 to generate a notification sound.
(S18) Generally, the temperature of the vaporizing section where the liquid fuel such as kerosene vaporizes well and is mixed with the combustion air to burn smoothly is 2
It is about 00 ° C. to 250 ° C., and in this embodiment, 220 ° C. is x
It is set in advance as ° C. The notification sound from the notification means 9 may be a continuous transmission sound, an intermittent transmission sound, or a synthesized voice.

Next, the combustion control circuit 20 outputs a timer start signal to the timer 10 after the notification means 9 outputs a notification sound, and causes the timer 10 to measure a certain time. It is determined whether or not the operation button 6 has been operated before the timer end signal is output to the circuit 20 (S19). If the operation button 6 has been operated, the electromagnetic pump is operated to dispense the liquid fuel into the combustion unit. 1, the combustion fan is operated to blow the combustion air to the combustion section 1 to generate an air-fuel mixture, and the air-fuel mixture is ignited by ignition means to start combustion and perform a heating operation. (S20)

When the operation button 6 is not operated during the predetermined time, the generation of the notification sound is performed a predetermined number of times n.
In this embodiment, a notification sound is generated at regular intervals up to five times (S21). If the operation button 6 is not operated, the operation of the illumination preheating start mode is stopped. (S2
2) The operation of the illumination preheating start mode is performed without operating the operation button 6 even before the notification sound is output after the preheating operation of the vaporization unit of the combustion unit 1 is completed and the notification sound is output a certain number of times. Even after stopping, if the user operates the drive button 6,
At that time, the storage of the setting of the illumination preheating start mode in the mode setting storage circuit 14 is erased and the illumination preheating start mode is released, and the combustion control circuit 20 performs the ignition operation as soon as the preheating operation is completed, and starts the combustion. A heating operation is performed.

As described above, if the lighting preheating start mode is set when going out, the lighting of the room is turned on when returning home at night, so that the preheating operation of the vaporizing section in the combustion section 1 is automatically performed. It is not necessary to operate the operation button 6 immediately after returning home, and another operation may be performed until the completion of the preparation for starting operation is notified by the notification sound, and the operation of the liquid fuel combustion device is performed by the notification sound. The operation can be prevented from being forgotten and is extremely convenient. In addition, since the operation button 6 must be manually operated to start ignition and combustion, combustion does not occur only by operating the illumination preheating start mode, so that it is extremely safe.
