Abstract

PROBLEM TO BE SOLVED: To provide a burner which can use a power-accumulation type power supply device which is easy in portability.

SOLUTION: A voltage application to a heater 12 is suppressed up until a detection temperature of evaporation part temperature detection means 17 reaches a preset prescribed temperature after starting electricity-carrying to the heater 12, and when the detection temperature of the evaporation part temperature detection means 17 reaches the preset prescribed temperature, the suppression of the voltage application to the heater 12 is loosened, and thereby, an abrupt increase of power consumption can be prevented by suppressing an inrush current by applying a voltage up until a temperature of the heater 12 is raised and reaches a prescribed temperature, thus allowing a use of the power-accumulation type power supply device which is small in output power. When the temperature of the evaporation part 13 is raised and reaches the prescribed temperature, a resistance value of the heater 12 is sufficiently raised, the power consumption is not abruptly increased even if loosening the suppression of the voltage application, a temperature rise after reaching the prescribed temperature is accelerated, and a time up to a start of combustion can be shortened.

By the way, with this conventional heater, if a ceramic heater or PTC heater, which has a characteristic of having a low resistance value at room temperature, is used, a large inrush current flows at the start of operation, and the power consumption instantly reaches 1000W, so it is difficult to use in Japan.

Further, in a fifth aspect of the present invention, the suppressing means suppresses the voltage by controlling the phase of the voltage applied to the vaporization section heating means.

According to claim 1 of the present invention, the voltage applied to the vaporizing section heating means is suppressed until the temperature detected by the vaporizing section temperature detecting means reaches a predetermined temperature after the start of electricity supply to the vaporizing section heating means. However, when the detected temperature of the vaporizing section temperature detection means reaches a predetermined temperature, the suppression of the voltage applied to the vaporizing section heating means is relaxed, so that the temperature of the vaporizing section heating means increases until it reaches the predetermined temperature. It is possible to suppress the inrush current by increasing the applied voltage to prevent instantaneous increase in power consumption, and to use a storage type power supply device with low output power.

In addition, when the temperature of the vaporization section rises and reaches a predetermined temperature, the resistance value of the vaporization section heating means becomes sufficiently high, and even if the suppression of the applied voltage is loosened, the power consumption does not increase momentarily, and the predetermined temperature By accelerating the temperature rise after reaching , the time until combustion starts can be hastened.

According to claim 2, the application to the vaporizing section heating means is continued until the detected resistance value of the vaporizing section heating means resistance value detecting section reaches a predetermined resistance value after the start of energization to the vaporizing section heating means.

According to claim 3, the timer section starts counting when electricity starts to be applied to the vaporizing section heating means, and the voltage is applied to the vaporizing section heating section until the time measured by the timer section reaches a predetermined time. When the voltage is suppressed and the time measured by the timer section reaches a predetermined time, the suppression of the voltage applied to the vaporization section heating means is relaxed, so the temperature of the vaporization section heating means rises and the time measured by the timer section is reduced. Until the predetermined time is reached, the applied voltage is suppressed to suppress the inrush current to prevent instantaneous increase in power consumption, and it is possible to use a storage type power supply device with low output power.

Further, according to claim 4, when the control unit determines that the input power source is other than the commercial power source, the control unit suppresses the voltage applied to the vaporizer heating means, so that the storage type power supply device with small output power and easy to carry is provided. Even if the storage power supply is used, a current larger than the rated current will not flow through the storage power supply, and the overcurrent protection circuit inside the storage power supply will be activated and the output of the storage power supply will stop. , it is possible to prevent the combustion machine from becoming inoperable.

Further, according to claim 5, the suppressing means suppresses the voltage applied to the vaporizing section heating means by controlling the phase, so that, for example, when starting energization to the vaporizing section heating means, the applied voltage is 1/4 wave.

Next, a first embodiment to which this invention is applied will be described based on the drawings.
1 is the equipment body of the Bunsen-type combustion machine, 2 is the burner which is the combustion part that generates combustion gas by burning a mixture of vaporized gas of liquid fuel and air, and 3 is the part that covers the flame of burner 2 and directs the combustion gas upward. 4 is a combustion chamber heat shield plate provided to cover the combustion chamber body 3; 5 is a blower device that takes air into the device body 1 from an air intake port 6; 7 is a combustion chamber body 3 and the combustion chamber heat shield plate 4, a hot air passageway is formed between the combustion chamber heat shield plate 4, and mixes the combustion gas with the air from the blower 5, and guides the mixture as hot air to the front of the equipment main body 1; This is a hot air outlet.

Further, from FIG. 2, 9 is an electromagnetic pump which is a fuel supply means provided on the upper part of the oil tray 10 storing liquid fuel (kerosene), and 11 is a means for heating the vaporizing part of the liquid fuel supplied from the electromagnetic pump 9. A vaporizing device consists of a vaporizing section 13 that is heated and vaporized by a heater 12 and a nozzle section 16 that is opened and closed by an opening/closing rod 15 that is moved by a solenoid 14. Reference numeral 17 is a vaporizing section temperature detection means that detects the temperature of the vaporizing section 13.
The heater 12 is a heater that has a low resistance value below room temperature, such as a PTC heater or a ceramic heater.
Furthermore, 18 is a burner mixing tube for mixing the vaporized gas from the vaporizer 11 and primary air to form a mixed gas, and 19 is for igniting this mixed gas at the nozzle 20 of the burner 2. It is an ignition device.

Reference numeral 21 denotes an operation section, which is provided with an operation switch 22 for instructing start and stop of operation, and a power source selection switch 23 for setting whether the input power source is a commercial power source or an easily portable power storage type power source device.
Reference numeral 24 denotes a control unit for controlling the operation of this combustion machine, which is mainly composed of a microcomputer. Reference numeral 25 denotes a suppressor capable of suppressing the voltage applied to the heater 12, which includes a zero-cross detection circuit 25a and a triac 25b. This is suppressed by controlling the phase of the voltage applied to the heater 12.

Next, the ignition operation of this combustor will be explained with reference to the flowchart of FIG.
First, when the operation switch 22 is turned on (S1) and a commercial power source is selected with the power source selection switch 23 (S2), a full-wave voltage is applied to the heater 12 of the vaporizer 11 to energize it (S3). The vaporization section 13 is heated by the heat generated by the heater 12 .

At this time, the control unit 24 determines that the input power source is a commercial power source, and applies a full-wave voltage to the heater 12, and the heater 12 is a heater that has a low resistance value below room temperature, such as a PTC heater or a ceramic heater. During combustion, the temperature becomes high and the resistance value becomes high, resulting in power consumption of about 200W. However, when electricity starts to flow, the resistance value is low at room temperature or below, so a large inrush current flows, resulting in instantaneous power consumption. reaches 1000 W, but since the input power source is a commercial power source, the power supply continues to be applied to the heater 12 without stopping the power supply.

Then, when the temperature detected by the vaporization section temperature detection means 17 rises to the vaporization temperature at which the vaporization section 13 can vaporize the liquid fuel (S4), the electromagnetic pump 9 is started and the liquid fuel flows into the vaporization section 13. The liquid fuel is fed (S5), and the liquid fuel is heated and vaporized to become vaporized gas.

Further, around the time of starting the electromagnetic pump 9, the blower device 5 is driven, the solenoid 14 is energized , the opening/closing rod 15 opens the nozzle part 16 (S6), and the vaporized gas from the vaporizing part 13 is released. is ejected from the nozzle portion 16 toward the burner mixing pipe 18.
Then, primary air is supplied to the burner mixing pipe 18 by the ejection force of this vaporized gas to form a mixed gas, and this mixed gas is ignited by the ignition device 19 at the nozzle part 20 of the burner 2 (S7) and combusted (S8). .

Further, when a power source other than a commercial power source is selected using the power source selection switch 23 in (S2), the control unit 24 determines that the input power source is an easily portable storage type power source device, and the voltage applied to the heater 12 is controlled by the suppressing means 25 to phase out the voltage applied to the heater 12. A quarter-wave voltage is applied to the heater 12 of the vaporizer 11 to energize it (S10), and the vaporizer 13 is heated by the heat generated by the heater 12.

At the start of this energization, the heater 12 has a low resistance value, but since the voltage applied to the heater 12 is phase-controlled to 1/4 wave by the suppressor 25, a large inrush current does not flow and the resistance value is low. Even if the power consumption increases, it will remain below the rated output power of the storage type power supply, so the overcurrent protection circuit inside the storage type power supply will not activate and stop the output of the storage type power supply. The heater 12 continues to be energized.

Then, when the temperature detected by the vaporization section temperature detection means 17 rises to a first predetermined temperature (S11), the control section 24 controls the temperature of the heater 12 to rise due to the temperature increase due to the energization, and the resistance value of the heater 12 to rise. Even if the applied voltage is changed from 1/4 wave to 1/2 wave, a large inrush current does not flow and the overcurrent protection circuit in the storage type power supply operates and the output of the storage type power supply stops. It is determined that this will not happen, and the voltage applied to the heater 12 is changed from 1/4 wave to 1/2 wave by the suppressing means 25 (S12).

Then, when the temperature detected by the vaporizer temperature detection means 17 rises to a second predetermined temperature higher than the predetermined first predetermined temperature (S13), the control section 24 causes the temperature to rise by energization and the resistance value of the heater 12 to increase. Even if the voltage increases further and the voltage applied to the heater 12 is changed from 1/2 wave to 3/4 wave, a large inrush current does not flow and the overcurrent protection circuit in the storage type power supply is activated and the storage type It is determined that the output of the power supply device will not stop, and the voltage applied to the heater 12 is changed from 1/2 wave to 3/4 wave by the suppressing means 25 (S14).

Then, when the temperature detected by the vaporizer temperature detection means 17 further increases to a third predetermined temperature higher than the predetermined second predetermined temperature (S15), the temperature increases by energization, and the resistance value of the heater 12 increases. Even if the voltage increases further and the voltage applied to the heater 12 is changed from 3/4 wave to full wave, a large inrush current does not flow and the overcurrent protection circuit in the storage type power supply is activated and the storage type It is determined that the output of the power supply device will not stop, and the phase control by the suppressing means 25 of the voltage applied to the heater 12 is ended (S16), and the process returns to (S3).

As described above, even if an easily portable storage type power supply device is used as an input power source for a combustion machine that uses a heater 12 that has a low resistance value below room temperature, such as a PTC heater or a ceramic heater, the temperature of the heater 12 When the voltage is low and the resistance value is low, the suppressing means 25 suppresses the voltage applied to the heater 12, so that a large inrush current does not flow when the heater 12 starts to be energized, and even if the power consumption momentarily increases, the power can be stored. Since the output power is lower than the rated output power of the power storage device, the heater 12 can continue to be energized without the overcurrent protection circuit in the power storage device being activated and the output of the power storage device being stopped.

Further, the suppressing means 25 controls the phase of the voltage applied to the heater 12 to change the voltage from 1/4 wave to 1/2 wave, 3/4 wave, and then full wave , that is, gradually reduces the conduction angle. Therefore , it is possible to relax the suppression of the applied voltage while preventing a large inrush current from flowing.

Next, a second embodiment to which this invention is applied will be described based on the drawings.
The second embodiment is provided with a vaporizer heating means resistance value detection section 26 that detects the resistance value of the heater 12, and the ignition operation of this combustor will be explained with reference to the flowchart of FIG.

Note that the control when the commercial power source is selected with the power source selection switch 23 is the same as in the first embodiment, and (S1) to (S8) in the flowchart of FIG. 5 are the same as (S1) in the flowchart of FIG. Since it is the same as from (S8), the explanation will be omitted.

Therefore, when a power source other than a commercial power source is selected using the power source selection switch 23 in (S2) in FIG. 25 (S17), a 1/4 wave voltage is applied to the heater 12 of the vaporizer 11 to energize it (S18), and the vaporizer 13 is heated by the heat generated by the heater 12.

At the start of this energization, the heater 12 has a low resistance value, but since the voltage applied to the heater 12 is phase-controlled to 1/4 wave by the suppressor 25, a large inrush current does not flow and the resistance value is low. Even if the power consumption increases, it will remain below the rated output power of the storage type power supply, so the overcurrent protection circuit inside the storage type power supply will not activate and stop the output of the storage type power supply. The heater 12 continues to be energized.

Then, when the detected resistance value of the vaporization section heating means resistance value detection section 26 rises to a predetermined first set resistance value (S19), the control section 24 causes the temperature to rise by energization and the resistance value of the heater 12 to rise. However, even if the voltage applied to the heater 12 is changed from 1/4 wave to 1/2 wave, a large inrush current does not flow and the overcurrent protection circuit in the storage type power supply is activated and the storage type power supply After determining that the output of the device will not stop, the voltage applied to the heater 12 is changed from 1/4 wave to 1/2 wave by the suppressing means 25 (S20).

Then, when the detected resistance value of the vaporization section heating means resistance value detection section 26 rises to a second set resistance value higher than the predetermined first set resistance value (S21), the control section 24 causes the temperature to rise by energization. Even if the resistance value of the heater 12 increases further and the voltage applied to the heater 12 is changed from 1/2 wave to 3/4 wave, a large inrush current will not flow and the overcurrent protection circuit in the storage type power supply device will be protected. is activated and the output of the storage type power supply device is not stopped, and the voltage applied to the heater 12 is changed from 1/2 wave to 3/4 wave by the suppressing means 25 (S22). .

Then, when the detected resistance value of the vaporization section heating means resistance value detection section 26 further increases to a third set resistance value higher than the predetermined second set resistance value (S23), the control section 24 causes the temperature to rise by energizing. Even if the resistance value of the heater 12 further increases and the voltage applied to the heater 12 is changed from 3/4 wave to full wave, no large inrush current flows and the overcurrent protection circuit in the storage type power supply device is activated. It is determined that the output of the storage type power supply device will not be stopped due to activation, and the phase control by the suppressing means 25 of the voltage applied to the heater 12 is terminated (S24), and the process returns to (S3). be.

As described above, even if an easily portable storage type power supply device is used as an input power source for a combustion machine that uses a heater 12 such as a PTC heater or a ceramic heater that has a low resistance value below room temperature, the temperature of the heater 12 When the voltage is low and the resistance value is low, the suppressing means 25 suppresses the voltage applied to the heater 12, so that a large inrush current does not flow when the heater 12 starts to be energized, and even if the power consumption momentarily increases, the power storage is maintained. Since the output power is lower than the rated output power of the power storage type power supply device, the heater 12 can continue to be energized without the overcurrent protection circuit in the storage type power supply device being activated and the output of the power storage type power supply device being stopped.

Further, the suppressing means 25 controls the phase of the voltage applied to the heater 12 to change the voltage from 1/4 wave to 1/2 wave, 3/4 wave, and then full wave , that is, gradually reduces the conduction angle. Therefore , it is possible to loosen the suppression of the applied voltage while preventing a large inrush current from flowing.

Next, a third embodiment to which this invention is applied will be described based on the drawings.
In the third embodiment, a timer section 27 is provided to measure time, and the ignition operation of this combustor will be explained with reference to the flowchart of FIG. 6.

Note that the control when the commercial power source is selected with the power source selection switch 23 is the same as in the first embodiment, and (S1) to (S8) in the flowchart of FIG. 6 are the same as (S1) in the flowchart of FIG. Since it is the same as from (S8), the explanation will be omitted.

Therefore, when a power source other than a commercial power source is selected using the power source selection switch 23 in (S2) in FIG. 25 (S25), a 1/4 wave voltage is applied to the heater 12 of the vaporizer 11 to energize it (S26), the vaporizer 13 is heated by the heat generated by the heater 12, and the timer section is activated. 27 start counting (S27).

At the start of this energization, the heater 12 has a low resistance value, but since the voltage applied to the heater 12 is phase-controlled to 1/4 wave by the suppressor 25, a large inrush current does not flow and the resistance value is low. Even if the power consumption increases, it will remain below the rated output power of the storage type power supply, so the overcurrent protection circuit inside the storage type power supply will not activate and stop the output of the storage type power supply. The heater 12 continues to be energized.

Then, when the time measured by the timer section 27 reaches a predetermined first set time (S28), the control section 24 controls the voltage applied to the heater 12 by increasing the temperature due to the energization and increasing the resistance value of the heater 12. Even if you change from 1/4 wave to 1/2 wave, a large inrush current will not flow and the overcurrent protection circuit in the storage type power supply will activate and the output of the storage type power supply will stop. It is determined that there is no problem, and the voltage applied to the heater 12 is changed from 1/4 wave to 1/2 wave by the suppressing means 25 (S29).

Then, the control section 24 resets the time measurement of the timer section 27 and starts time measurement again (S30).
Then, when the time measured by the timer section 27 reaches a predetermined second set time (S31), the temperature rises due to energization, the resistance value of the heater 12 further increases, and the voltage applied to the heater 12 is reduced by 1/2. Even if you change from wave to 3/4 wave, make sure that a large inrush current will not flow and the overcurrent protection circuit in the storage power supply will not activate and stop the output of the storage power supply. Based on the judgment, the voltage applied to the heater 12 is changed from 1/2 wave to 3/4 wave by the suppressing means 25 (S32).

Then, the control section 24 resets the time measurement of the timer section 27 and starts time measurement again (S33).
Then, the control unit 24 determines that when the time measured by the timer unit 27 reaches a predetermined third set time (S34), the temperature rises due to the energization, the resistance value of the heater 12 further increases, and the voltage is applied to the heater 12. Even if the voltage is changed from 3/4 wave to full wave, a large inrush current will not flow and the overcurrent protection circuit in the storage type power supply will activate and the output of the storage type power supply will stop. When it is determined that there is no voltage, the phase control by the suppressing means 25 of the voltage applied to the heater 12 is terminated (S35), the time measurement of the timer section 27 is stopped and reset (S36), and the process returns to (S3). .

As described above, even if an easily portable storage type power supply device is used as an input power source for a combustion machine that uses a heater 12 that has a low resistance value below room temperature, such as a PTC heater or a ceramic heater, the temperature of the heater 12 When the voltage is low and the resistance value is low, the suppressing means 25 suppresses the voltage applied to the heater 12, so that a large inrush current does not flow when the heater 12 starts to be energized, and even if the power consumption momentarily increases, the power can be stored. Since the output power is lower than the rated output power of the power storage device, the heater 12 can continue to be energized without the overcurrent protection circuit in the power storage device being activated and the output of the power storage device being stopped.

Further, the suppressing means 25 controls the phase of the voltage applied to the heater 12 to change the voltage from 1/4 wave to 1/2 wave, 3/4 wave, and then full wave , that is, gradually reduces the conduction angle. Therefore , it is possible to loosen the suppression of the applied voltage while preventing a large inrush current from flowing.

Furthermore, although this embodiment has been described using a Bunsen-type combustion machine, the present invention is not limited to this, and a pot-type combustion machine shown in FIG. 7 may also be used, and 12 in FIG. A heater that directly heats and burns naturally vaporized kerosene, such as a ceramic heater, is used, and when an easily portable storage type power supply device is used as an input power source, the voltage applied to this heater 12 is suppressed by the suppressing means 25.

In the present embodiment, the suppressing means 25 suppresses the voltage applied to the heater 12 by controlling the phase thereof; however, the present invention is not limited to this. For example, a variable resistance device may be connected in series to the heater 12 to suppress the voltage applied to the heater 12. The resistance value of the variable resistance device may be increased at the start of energization, and the resistance value of the variable resistance device may be gradually decreased to loosen the suppression of the voltage applied to the heater 12.
