The block diagram controlled about the energising of heater 18 shown in Fig. 4, relevant heater 18 shown in Fig. 5
The circuit structure that energising controls.As being connected in series having heaters 18 on the power supply unit 4 of alternating current power supply and opening
GUAN spot 5.Having test section 6 and control portion 8 it addition, connect on power supply unit 4, this control portion 8 receives test section 6
Output make above-mentioned switch portion 5 turn on.That is, hair-protecting device possess power supply unit 4, heater (heating part) 18,
Switch portion 5, control portion 8 and test section 6.Switch portion 5 possesses at least one switch element.It is to say,
Switch portion 5 both can possess a switch element, it is also possible to possesses multiple switch element.
The test section 6 receiving the electric power from power supply unit 4 via rectification part 7 possesses rectified portion 7 half-wave
Voltage after rectification carry out the resistance 61 of dividing potential drop, 62, the voltage of dividing potential drop gained be applied to the crystal of base stage

The control portion 8 of L level (low level) signal it is transfused to such as with single-chip when transistor 63 turns on
Microcomputer is main structure key element.The control portion 8 receiving above-mentioned L level signal starts built-in two
The counting of timer (the first timer, the second timer), then believed pulse in the time of each timer
Number output is to the primary side of photoelectricity bidirectional triode thyristor (photo triac) 80.
Two-way by above-mentioned photoelectricity with the switch portion 5 being made up of bidirectional triode thyristor that heater 18 is connected in series
The conducting of the primary side of controllable silicon 80 and turn on heater 18 is energized.In figure, 51 is DC source.

On the other hand, about the power supply to heater 18, it is arranged to cold at pathogenic wind-warm switching switch 30
Do not carry out this power supply during wind, and when pathogenic wind-warm switching switch 30 is arranged to hot blast, enter as follows
This power supply of row.
Rise to the time point of assigned voltage, inspection from zero passage at the voltage of the power supply unit 4 as alternating current power supply
Transistor 63 in survey portion 6 becomes conducting, and L level voltage is input to the input port in control portion 8.
Control portion 8 detects that according to the input of this L level voltage the voltage of power supply unit 4 rises to regulation electricity
The situation of pressure, starts the counting of two timers as described above.
Then, as it is shown in figure 1, then (time to count value T1, in exchange in the time of the first timer
The supply frequency of power supply is for after substantially 10ms in the case of 50Hz) pulse signal (power on signal) is delivered to
Photoelectricity bidirectional triode thyristor 80 makes switch portion 5 turn on.
It addition, in the time of the second timer, then (time to count value T2, at the power supply of alternating current power supply
Frequency is in the case of 50Hz after substantially 20ms) also pulse signal is delivered to photoelectricity bidirectional triode thyristor 80
Switch portion 5 is made to turn on.
When now the assigned voltage of alternating current power supply being set to 8.6V, the supply frequency in alternating current power supply is 50Hz
In the case of, test section 6 detect that supply voltage reaches assigned voltage and lighting from zero-crossing timing
After 0.42ms, the time point reaching assigned voltage with supply voltage starts the first timer and for starting point
The counting of two timers.
Then, carry out the phase controlling of next half period in the time then control portion 8 of the first timer,
The phase controlling of next one half period is then carried out in the time of the second timer.
That the half period carrying out voltage detecting is carried out phase controlling but to the next half period and with
Laggard line phase controls, and this is to reach the time till assigned voltage regardless of supply voltage, all
Increase the angle of flow and guarantee turn on angle.
It addition, the hair-protecting device involved by present embodiment arranges two timers, not only carry out the next one
The phase controlling of half period, also carries out the phase controlling of next one half period, it is possible to utilize once
Voltage detecting carries out the phase controlling of a periodic quantity.
It is additionally, since and assigned voltage is set as the highest voltage of 8.6V, even if outside the most such as 2V
Portion's noise is superimposed on test section 6 or its structure member, due to external noise be assigned voltage (8.6V) below,
Therefore the false triggering of the heater 18 preventing error detection from being caused it also is able to.
Here, be connected by lead-in wire between power supply unit 4 with rectification part 7, therefore external noise is prone to
Superposition, test section 6 likely can carry out misoperation due to this noise.Thus, by by assigned voltage
It is set to the highest so that being difficult to the effect of noise below by assigned voltage and being prevented from by mistake
Action.But, it is set to assigned voltage the highest there is also problem.
It is to say, the voltage as the power supply unit 4 of alternating current power supply is the highest, then utilize resistance 61,62 right
The tolerance of the voltage that this voltage carries out dividing potential drop gained is the biggest.It addition, the voltage waveform of alternating current power supply is sinusoidal
Curve, closer to the peak value of voltage, then the change in voltage of time per unit is the least.
Therefore, assigned voltage is set to the highest, then lights from time that the voltage of alternating current power supply is 0V
The tolerance of the time (voltage from zero passage reaches the time) reaching assigned voltage is the biggest.
Assigned voltage has the tolerance of 5% due to the deviation etc. of resistance value.Such as, when by assigned voltage
When being set as 20V, alternating current power supply (100V, 50Hz) voltage is at the 452 μ s (microsecond) lighted from the time of 0V
After reach 20V.In the case of assigned voltage is 20V ± 5%, the voltage from zero passage reaches the time and is
452μs±23μs。
Additionally, due within the frequency variation of alternating current power supply is 1%, therefore in the range of above-mentioned tolerance
Can ignore.
In the case of assigned voltage is 8.6V ± 5%, the voltage from zero passage reaches the time and is
193 μ s ± 10 μ s (with reference to Fig. 6).From the point of view of in terms of these tolerances, the tolerance making assigned voltage is needed to be led
It is 10 below μ s that the voltage from zero passage caused reaches the tolerance of time.
That is, for the misoperation preventing external noise from being caused, not only to be set to the greatest extent may be used by assigned voltage
Can be high, in addition it is also necessary to the tolerance making the voltage from zero passage reach the time is 10 below μ s.
Assigned voltage is set as, and 8.6V is for the foregoing reasons.By the way,
8.6V ± 5%=8.17～9.03V, in this case, it is 183 μ s～203 μ s, voltage that voltage reaches the time
The tolerance reaching the time is ± 10 μ s.But, the present invention is not limited to the situation that assigned voltage is 8.6V.
The circuit structure of test section 6 is also not limited to above-mentioned example.Such as, as it is shown in fig. 7, test section 6
Rectification diode 65,66 can also be utilized.Test section 6 can also use replaces the resistance 62 in Fig. 7
The structure of assigned voltage is improved for constant-voltage diode.
Setting according to pathogenic wind-warm switching switch 30 carrys out the time of the timer in Variation control portion 8 to count value.
By this change, the timing that produces of the power on signal of heater 18 is switched and heating based on phase controlling
The current on time of device 18 changes, and therefore pathogenic wind-warm also changes.
(embodiment 2)
The structure of embodiment 2 is identical with embodiment 1, but here, as shown in Figure 8, this embodiment party
The hair-protecting device of formula carries out reaching half period of assigned voltage identical half cycle with detection AC supply voltage
The phase controlling of phase (the first half period) and the phase controlling of its next half period (the second half period).
In this case, it is also possible to the generation of the misoperation that the impact of suppression external noise is caused.
The angle of flow of phase controlling is reduced to reduce the state of pathogenic wind-warm additionally, figure 8 illustrates.Subsidiary
Ground is said, in illustrated example, to count value T1, is set to 5ms the time of the first timer, by the second timing
The time of device is set to 15ms to count value T2.
But, carrying out reaching half period of assigned voltage identical half cycle with the voltage of detection alternating current power supply
In the case of the phase controlling of phase, can only be at the voltage lighting alternating current power supply from the zero-crossing timing of alternating current power supply
The energising to heater 18 is carried out after reaching assigned voltage.
And, the time till the energising to heater 18 in from zero-crossing timing point to half period is elongated
Time, the generation of electromagnetic interference wave can be caused.
In order to more than 6dB will be ensured about the surplus (margin) of electromagnetic interference wave (noise terminal voltage),
Preferably make to reach the time point of the 0V time to heater 18 is energized from AC supply voltage
It is 500 below μ s.
And, in the case of assigned voltage is set as aforesaid 8.6V, if supply frequency is 50Hz,
Then AC supply voltage reaches 8.6V is after the 0.42ms lighted from zero-crossing timing.Accordingly, it is considered to handing over
Stream the variation in voltage of power supply, the tolerance of resistance, the signal propagation delay time of photoelectricity bidirectional triode thyristor 80,
Software processes postpones, the tolerance etc. of timer, at the 500 μ s lighted from zero-crossing timing within the same half period
It is difficult for starting in the following time heater 18 energising.
Thus, the generation of misoperation that is based on suppressing the impact of external noise to be caused and can pressing down
The viewpoint of the produced electromagnetic interference wave of system, it is preferred that the voltage of detection alternating current power supply reaches regulation electricity
Heater 18 is carried out by the half period of pressure with according to detecting the voltage of alternating current power supply to reach assigned voltage
Energising control between stagger the half period.
Additionally, offset is not limited to the half period, it is also possible to be a cycle more than.
(embodiment 3)
The structure of embodiment 3 is identical with embodiment 1, the action of embodiment 3 also with embodiment more than 1
Identical, but the time at timer is exported photoelectricity to time point by the hair-protecting device of present embodiment
The pulse signal of bidirectional triode thyristor 80 is as shown in Figure 9 with 0.5ms for interval repeatedly.
Additionally, the interval of first and second or its later pulse signal is without for 0.5ms,
Can take to be spaced arbitrarily between next zero passage at first power on signal.
Even if failing the feelings utilizing first pulse signal that heater 18 is energized for some reason
Under condition, it is also possible to utilize second and heater 18 is energized by later pulse signal such that it is able to more may be used
By ground, heater 18 is energized.
It addition, illustrate the situation that supply frequency is 50Hz of alternating current power supply in each of the above-described embodiment, and
In the case of supply frequency is 60Hz, entered to count value by the time of the timer in Variation control portion 8
Row reply.
It is achieved in that and is stored the time corresponding with each supply frequency to count value in advance
In table in being arranged at control portion 8 etc., reach the time of assigned voltage by measuring AC supply voltage
Cause control portion 8, interval obtains supply frequency.Then, by reading the corresponding time to count value, control
Portion 8 processed makes to play the time till being energized heater 18 and power supply frequency from the time point reaching assigned voltage
Rate matches.
Its result, even if supply frequency is different, heater 18 owing to the region using hair-protecting device is different
Also will not false triggering such that it is able to reliably drive heater 18.
Additionally, in the case of supply frequency is 60Hz, it is from zero-crossing timing that alternating current power supply reaches 8.6V
(as previously mentioned for after 0.42ms in the case of 50Hz) after the 0.38ms lighted.In phase controlling to be made
Angle of flow maximum in the case of, it is preferred that when supply frequency is 50Hz, by the first timer
Time is set to 9.8ms to count value T1, and to count value T2, are set to 19.8ms the time of the second timer,
When supply frequency is 60Hz, the time of the first timer is set to 8.17ms to count value T1, by second
The time of timer is set to 16.50ms to count value T2.
Either in the case of which kind of, it is all to start heating before and after the 0.2ms lighted from zero-crossing timing
Device 18 is energized, and therefore starts within the time of 500 below μ s based on meeting from the viewpoint of electromagnetic interference wave
State to heater 18 energising.
(embodiment 4)
