With reference to accompanying drawing, embodiments of the present invention are described below.In addition, the present invention is not limited to this embodiment.
(embodiment 1)
Fig. 2 and Fig. 3 represent an example of the structure of hair-protecting device involved in the present invention.Housing 1 and handle 2 by tubular form shell, the front end face of this housing 1 and rear end face opening, and the top that this handle 2 rotates freely the protuberance outstanding with the position by rear end of the outer peripheral face from housing 1 links.
Be built-in with the air quantity change-over switch 20 that is also used as power switch from the handle 2 of end extracting power supply cord 25, this air quantity change-over switch 20 is switched by slidingtype operating portion.
Housing 1, taking rear end face as suction inlet 11, taking front end face as ejiction opening 12, possesses the wind- tunnel 13,14 that front and back link, the fan 16 that possesses motor 15 and driven by motor 15 in the wind-tunnel 13 of rear portion side in inside.
In the wind-tunnel 14 of toe lateral, dispose and twist in cross section and be the heater (heating part) 18 on cross heater substrate 17, the front end of wind-tunnel 14 is connected with nozzle 19.
Between the inner surface of housing 1 and the outer surface of wind- tunnel 13,14, dispose as shown in Figure 3 wind-warm syndrome change-over switch 30, control circuit substrate 31, high voltage discharge circuit 32 and electrostatically atomizing unit 33.
Electrostatically atomizing unit 33 is to making above-mentioned moisture atomization by utilizing the cooling airborne moisture condensing that amber ear note (Peltier) element carries out to apply the high voltage being produced by high voltage discharge circuit 32, generate thus charged particulate water, this electrostatically atomizing unit 33 sprays above-mentioned particulate water from nozzle 34.
Shown in Fig. 4 about the block diagram of the energising control of heater 18, shown in Fig. 5 about the circuit structure of the energising control of heater 18.On power supply unit 4 as AC power, be connected in series having heaters 18 and switch portion 5.In addition, be connected with test section 6 and control part 8 on power supply unit 4, the output that this control part 8 receives test section 6 makes above-mentioned switch portion 5 conductings., hair-protecting device possesses power supply unit 4, heater (heating part) 18, switch portion 5, control part 8 and test section 6.Switch portion 5 possesses at least one switch element.That is to say, switch portion 5 both can possess a switch element, also can possess multiple switch elements.
Via rectification part 7 receive from the test section 6 of the electric power of power supply unit 4 possess to the voltage after rectification part 7 halfwave rectifier carry out the resistance 61,62 of dividing potential drop, the voltage of dividing potential drop gained is applied to transistor 63 and the resistance 64 of base stage.
In the time of transistor 63 conducting, be transfused to the control part 8 of L level (low level) signal for example taking single-chip microcomputer as main structure key element.The control part 8 that receives above-mentioned L level signal starts the counting of two built-in timers (the first timer, the second timer), in the then primary side to photoelectricity bidirectional triode thyristor (photo triac) 80 by output of pulse signal of the time of each timer.
The switch portion being formed by bidirectional triode thyristor 5 being connected in series with heater 18 by the conducting of the primary side of above-mentioned photoelectricity bidirectional triode thyristor 80 conducting so that heater 18 is switched on.In figure, 51 is dc source.
In the time switching on power by the operation of air quantity change-over switch 20, from power supply unit 4, motor 15 is applied to voltage, to carry out drive fan 16 with the corresponding rotating speed of the air quantity setting.By the driving of fan 16, the air attracting from suction inlet 11 passes through in wind- tunnel 13,14, sprays from ejiction opening 12 through nozzle 19.
On the other hand, supply with about the electric power to heater 18, in the time that wind-warm syndrome change-over switch 30 is set to cold wind, do not carry out this electric power supply, and in the time that wind-warm syndrome change-over switch 30 is set to hot blast, carry out like that as follows this electric power supply.
Rise to the time point of assigned voltage from zero passage at the voltage of the power supply unit 4 as AC power, the transistor 63 in test section 6 becomes conducting, and L level voltage is input to the input port of control part 8.
Then, as shown in Figure 1, time of the first timer then (time is to count value T1, is for after 10ms roughly 50Hz in the supply frequency of AC power) pulse signal (power on signal) delivered to photoelectricity bidirectional triode thyristor 80 make switch portion 5 conductings.
In addition, time of the second timer then (time, to count value T2, is to be roughly after 20ms 50Hz in the supply frequency of AC power) also pulse signal is delivered to photoelectricity bidirectional triode thyristor 80 and is made switch portion 5 conductings.
While now the assigned voltage of AC power being made as to 8.6V, be 50Hz in the supply frequency of AC power, detect that by test section 6 it is the 0.42ms lighting from zero-crossing timing that supply voltage reaches assigned voltage, the time point that reaches assigned voltage taking supply voltage starts the counting of the first timer and the second timer as starting point.
Then, time of the first timer then control part 8 carry out the phase controlling of next half period, then carry out the phase controlling of next half period again in the time of the second timer.
Be not half period to carrying out voltage detecting to carry out phase controlling but to the next half period and carry out phase controlling later, this is in order to reach the time till assigned voltage regardless of supply voltage, all to increase the angle of flow and guarantee energising amount.
In addition, the related hair-protecting device of present embodiment arranges two timers, not only carry out the phase controlling of next half period, also carry out the phase controlling of next half period again, can utilize thus primary voltage to detect to carry out the phase controlling of one-period amount.
And, owing to assigned voltage being set as to the voltage that 8.6V is high like this, even if therefore the external noise of for example 2V is superimposed on test section 6 or its structure member, because external noise is below assigned voltage (8.6V), therefore also can prevent the false triggering of the heater 18 that error detection causes.
At this, between power supply unit 4 and rectification part 7, be connected by going between, therefore external noise is easy to stack, and test section 6 likely can be because this noise carries out misoperation.Thereby, by assigned voltage being set to such an extent that highly as far as possible can prevent misoperation with the impact that makes to be difficult to be subject to the noise below assigned voltage.But, assigned voltage is set to get Tai Gao and also has problems.
That is to say, higher as the voltage of the power supply unit 4 of AC power, utilize 61,62 pairs of these voltages of resistance to carry out the tolerance of voltage of dividing potential drop gained larger.In addition, the voltage waveform of AC power is sine curve, more approaches the peak value of voltage, and the voltage change of time per unit is less.
Therefore, assigned voltage is set highlyer, the tolerance of time that reaches assigned voltage (voltage from zero passage reaches the time) of lighting time that is 0V from the voltage of AC power is larger.
Assigned voltage is because deviation of resistance value etc. has 5% tolerance.For example, in the time that assigned voltage is set as to 20V, AC power (100V, 50Hz) voltage reaches 20V the 452 μ s (microsecond) that light from the time of 0V.In the situation that assigned voltage is 20V ± 5%, it is 452 μ s ± 23 μ s that the voltage from zero passage reaches the time.
In addition, because the frequency variation of AC power is in 1%, therefore in the scope of above-mentioned tolerance, can ignore.
In the situation that assigned voltage is 8.6V ± 5%, it is 193 μ s ± 10 μ s (with reference to Fig. 6) that the voltage from zero passage reaches the time.From the aspect of these tolerances, the tolerance that the voltage from zero passage that need to make the tolerance of assigned voltage cause reaches the time is below 10 μ s.
That is, for the misoperation that prevents that external noise from causing, not only assigned voltage will be set high as far as possible, also needing to make voltage from zero passage to reach the tolerance of time is below 10 μ s.
It is for the foregoing reasons that assigned voltage is set as to 8.6V.By the way, 8.6V ± 5%=8.17～9.03V, in this case, it is 183 μ s～203 μ s that voltage reaches the time, the tolerance that voltage reaches 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.For example, as shown in Figure 7, test section 6 also can utilize diode 65,66 for rectification.Test section 6 can also adopt the structure that the resistance in Fig. 7 62 is replaced into constant-voltage diode and improves assigned voltage.
The time of changing the timer of control part 8 according to the setting of wind-warm syndrome change-over switch 30 arrives count value.By this change, the generation of the power on signal of heater 18 timing is switched and the current on time of heater 18 based on phase controlling changes, and therefore wind-warm syndrome also changes.
(embodiment 2)
The structure of embodiment 2 is identical with embodiment 1, but at this, as shown in Figure 8, the hair-protecting device of present embodiment carry out with detect phase controlling that AC supply voltage reaches the identical half period (the first half period) of half period of assigned voltage with and the phase controlling of next half period (the second half period).In this case, also can suppress the generation of the misoperation that the impact of external noise causes.
In addition, figure 8 illustrates the angle of flow that reduces phase controlling and reduce the state of wind-warm syndrome.By the way, in illustrated example, the time of the first timer is made as to 5ms to count value T1, the time of the second timer is made as to 15ms to count value T2.
But, in the case of carrying out and detecting the voltage of AC power and reach the phase controlling of identical half period of half period of assigned voltage, can only after reaching assigned voltage, the voltage of lighting AC power from the zero-crossing timing of AC power carry out the energising to heater 18.
And, when putting from zero-crossing timing till the time of the energising to heater 18 in the half period when elongated, can cause the generation of electromagnetic interference wave.
In order to guarantee for more than 6dB about the surplus (margin) of electromagnetic interference wave (noise terminal voltage), preferably make from AC supply voltage reach 0V time point till to the time of heater 18 energising be below 500 μ s.
And in the situation that assigned voltage is set as to aforesaid 8.6V, if supply frequency is 50Hz, to reach 8.6V be the 0.42ms lighting from zero-crossing timing to AC supply voltage.Therefore, signal propagation delay time, software processing delay, the tolerance of timer etc. of considering tolerance, the photoelectricity bidirectional triode thyristor 80 of variation in voltage, the resistance of AC power, it is difficult in the time within the same half period below the 500 μ s that light from zero-crossing timing, starting 18 energisings to heater.
Thereby, the generation of the misoperation that the impact based on suppressing external noise causes and can suppress the viewpoint of produced electromagnetic interference wave, preferably, detecting half period that the voltage of AC power reaches assigned voltage and basis detects that the voltage of AC power reaches assigned voltage and staggers the half period between energising control that heater 18 is carried out.
In addition, the amount of staggering is not limited to the half period, can be also more than one-period.
(embodiment 3)
The structure of embodiment 3 is identical with embodiment 1, the action of embodiment 3 is also almost identical with embodiment 1, but the pulse signal that the hair-protecting device of present embodiment outputs to photoelectricity bidirectional triode thyristor 80 to time point by the time at timer as shown in Figure 9 taking 0.5ms as interval repeatedly.
In addition, interval arbitrarily, without being 0.5ms, can be taked between next zero passage at first power on signal in the interval of first and second or its later pulse signal.
Even in the situation that failing to utilize for some reason first pulse signal to switch on to heater 18, also can utilize second and later pulse signal to switch on to heater 18, thereby can switch on to heater 18 more reliably.
In addition, the situation that the supply frequency that AC power has been described is in each of the above-described embodiment 50Hz, and in the situation that supply frequency is 60Hz, the time of the timer by changing control part 8 tackles to count value.
It is realized in the following way: in advance the time corresponding with each supply frequency is stored in to count value in the table that is arranged in control part 8 etc., the time interval cause control part 8 that reaches assigned voltage by measuring AC supply voltage is obtained supply frequency.Then,, by reading the corresponding time to count value, time and supply frequency that control part 8 plays till heater 18 is switched on the time point from reaching assigned voltage match.
Its result, though owing to using the region difference of hair-protecting device supply frequency difference, heater 18 can false triggering yet, thereby can drive reliably heater 18.
In addition,, in the situation that supply frequency is 60Hz, it is the 0.38ms lighting from zero-crossing timing (be 0.42ms as previously mentioned in the situation that of 50Hz after) that AC power reaches 8.6V.In the case of making the angle of flow maximum in phase controlling, preferably, in the time that supply frequency is 50Hz, the time of the first timer is made as to 9.8ms to count value T1, the time of the second timer is made as to 19.8ms to count value T2, in the time that supply frequency is 60Hz, the time of the first timer is made as to 8.17ms to count value T1, the time of the second timer is made as to 16.50ms to count value T2.
No matter being in which kind of situation, is all to start heater 18 to switch on before and after the 0.2ms that lights from zero-crossing timing, and therefore the viewpoint based on electromagnetic interference wave meets and in the time below 500 μ s, starts state that heater 18 is switched on.
(embodiment 4)
In embodiment 1, the action of the switch portion 5 of utilizing photoelectricity bidirectional triode thyristor 80 to control to be formed by bidirectional triode thyristor, but in embodiment 4, as shown in figure 10, can form the circuit that the action of switch portion 5 is controlled by transistor 90, resistance 91,92, capacitor 93 and diode 94.In this case, can make circuit structure cheapness and simplify.
Show the time point that reaches assigned voltage (8.6V) taking the rising of AC power and carry out the example of the phase controlling of heater 18 as starting point, but the time point that can certainly reach the negative voltage of regulation taking the decline of AC power carries out phase controlling as starting point.
(embodiment 5)
