The effect of invention
The air drier of the present invention is configured to, and control unit 29 receives the output signal and controller 12 of temperature sensor 25 Adjustment signal control the driving condition of motor 5 and heater 6.Specifically, control unit 29 is in motor 5 and heater Under 6 powered operating conditions, it can be come according to the driving rotating speed of the adjustment signal adjustment motor 5 exported from controller 12 Increase and decrease adjustment is carried out to the air output of blowing fan 4.On this basis, control unit 29 is configured to, and increases and decreases in the air output of blowing fan 4 In the state of, increase and decrease adjustment can be carried out according to the detection signal automatically thermal output to heater 6 of temperature sensor 25, with The increase and decrease of the air output of blowing fan 4 independently keeps constant hot blast temperature.
According to the air drier for possessing control unit 29 as described above, independently can automatically be carried out with environment temperature The adjustment of the hot blast temperature of air drier, to supply the hot wind of the air quantity of suitable multiple hair treatment states and temperature.In addition, , also can be with the case that the supply air quantity of blowing fan 4 is adjusted to the air quantity liked even in user's operation controller 12 The change of the supply air quantity of blowing fan 4 is independently by detection signal of the control unit 29 based on temperature sensor 25 automatically to heating The thermal output of device 6 carries out increase and decrease adjustment, keeps constant hot blast temperature.
Control unit 29 is in the case where the adjustment state of controller 12 is slow adjustment, the detection based on temperature sensor 25 The thermal output that signal is performed to heater 6 carries out the normality control of increase and decrease adjustment, keeps constant hot blast temperature.In this way, controlling Device 12 processed carried out in the case of slow adjusted normality control be because, the driving rotating speed of motor 5 caused by slow adjustment Amplitude of variation is small, it is thus possible to reliably follows the adjustment action of motor 5 and definitely controls heater 6 with normality control Thermal output.If in addition, controller 12 adjustment state to be corrected control in the case of quick-adjustsing, can be in correspondence The thermal output of heater 6 is suitably controlled in the state of the adjustment action of motor 5, to make the heat from air drier supply The temperature of wind keeps constant hot blast temperature close to target temperature.In addition, continue when controller 12 is readily adjusted In the case that normality controls, the adjustment action of controller 12 can not be followed and control the thermal output of heater 6 rapidly so that from heat The temperature of the hot wind of wind drying machine supply greatly deviates from target temperature.
In the case where the adjustment state of controller 12 adjusts for rapid decrease, if control unit 29 is changed to Corrective control, Make the minimum outputization of thermal output of heater 6 and drive scheduled time T1, then can with motor 5 drive rotating speed drastically under Drop accordingly reduces the thermal output of heater 6.Thereby, it is possible to prevent heater 6 to be absorbed in overshoot.In addition, start Corrective control simultaneously Recover to normality to control after scheduled time T1, keep constant the hot blast temperature from air drier supply.Make heating In the case of the minimum outputization of the thermal output of device 6, stop supply to the driving current of heater 6, or reduce driving current Pulse width and time per unit umber of pulse.
Controller 12 adjustment amount in order to control device 12 adjustment stroke more than 50% rapid decrease adjustment situation Under, if control unit 29 makes the minimum outputization of the thermal output of heater 6 from normality control conversion to Corrective control, can prevent The thermal output of heater 6 is by unnecessarily big adjustment.For example, the adjustment stroke of the adjustment amount device 12 in order to control in controller 12 In the case of 30%, if being corrected control to make the minimum outputization of the thermal output of heater 6, the control for being used to correct will become Obtain excessively so that control result is significantly disperseed from target temperature.As a result, the hot blast temperature from air drier supply is steady Determine to need the time to target temperature.Control unit 29 recovers to normality control from being started Corrective control after scheduled time T1 System, keeps constant the hot blast temperature from air drier supply.
In the case where the adjustment state of controller 12 adjusts for quick increase, if control unit 29 is changed to Corrective control, , then can be with the driving rotating speed of motor 5 drastically to make the thermal output maximum output of heater 6 and drive scheduled time T2 Increase accordingly increase heater 6 thermal output.Thereby, it is possible to prevent heater 6 to be absorbed in undershoot.In addition, starting school certainly Positive control rises to recover to normality to control after scheduled time T2, keeps constant the hot blast temperature from air drier supply. In the case where making the thermal output maximum output of heater 6, make supply maximum to the driving current of heater 6, or increase The pulse width of driving current and the umber of pulse of time per unit.
In the situation of adjustment amount more than the 50% quick increase adjustment of the adjustment stroke of device 12 in order to control of controller 12 Under, if control unit 29 makes the thermal output maximum output of heater 6 from normality control conversion to Corrective control, can prevent The thermal output of heater 6 is by unnecessarily big adjustment.For example, the adjustment stroke of the adjustment amount device 12 in order to control in controller 12 In the case of 20%, if being corrected control to make the thermal output maximum output of heater 6, the control for being used to correct will become Obtain excessively so that control result is significantly disperseed from target temperature.As a result, the hot blast temperature from air drier supply is steady Determine to need the time to target temperature.Control unit 29 recovers to normality control from being started Corrective control after scheduled time T1 System, keeps constant the hot blast temperature from air drier supply.
When controller 12 is adjusted by rapid decrease, control unit 29 is changed to Corrective control to make the thermal output of heater 6 Minimum outputization, when controller 12 is rapidly populated adjustment, control unit 29 is changed to Corrective control to make the thermal output of heater 6 Maximum output.According to such control mode, can accordingly make with all quick adjustment actions carried out by controller 12 The thermal output optimization of heater 6, keeps constant the hot blast temperature from air drier supply.
The driving time T1 and controller 12 for the heater 6 being set as when controller 12 is adjusted by rapid decrease are quickly increased The driving time T2 of the heater 6 during adjustment is added to meet inequality (T1 ＞ T2) because of following reason.Thermal output is by maximum output The temperature of the heater 6 of the state of change is from the state that is heated and keeping big heat before by maximum output into one Step is heated so that the increase degree of heat becomes larger.Therefore, close-target temperature can be inscribed in the shorter time, and easily fall into Enter overshoot.Therefore, by being controlled from Corrective control rapid translating to normality, reliably to avoid being absorbed in overshoot.So as to time T1 Relation with time T2 is (T1 ＞ T2).
After controller 12 is adjusted by rapid decrease, the situation of adjustment is rapidly populated in scheduled time T1 internal controller 12 Under, control unit 29 controls the thermal output of heater 6 because of following reason based on normality control.In controller 12 by rapid decrease In the state of adjustment, control unit 29 is temporarily switched to Corrective control to make the minimum outputization of the thermal output of heater 6.If however, Before autotomying and shifting to after Corrective control by scheduled time T1, controller 12 is rapidly populated adjustment, then must be in heater 6 Wen Duxiajiang Corrective control terminate before carry out Corrective control to the increased direction of temperature.In this case, due to The thermal output of heater 6 is by maximum output, thus heater 6 is easily trapped into overshoot state.To prevent the problem of such, control Portion 29 carries out the normality control of the detection signal based on temperature sensor 25 with not making the thermal output maximum output of heater 6.
After controller 12 is rapidly populated adjustment, in the situation that scheduled time T2 internal controller 12 is adjusted by rapid decrease Under, control unit 29 controls the thermal output of heater 6 because of following reason based on normality control.It is rapidly populated in controller 12 In the state of adjustment, control unit 29 is temporarily switched to Corrective control to make the thermal output maximum output of heater 6.If however, Autotomy shift to after Corrective control by scheduled time T2 before controller 12 adjusted by rapid decrease, then must be in heater 6 The increased Corrective control of temperature terminate before carry out to temperature decline direction Corrective control.In this case, due to The thermal output of heater 6 is by minimum outputization, thus heater 6 is easily trapped into undershoot state.To prevent the problem of such, control Portion 29 carries out the normality control of the detection signal based on temperature sensor 25 with not making the minimum outputization of the thermal output of heater 6.
Another air drier of the present invention is configured to, and control unit 29 receives output signal and the control of temperature sensor 25 The adjustment signal of device 12 controls the driving condition of motor 5 and heater 6.Specifically, control unit 29 in motor 5 and adds Under hot 6 powered operating condition of device, the thermal output of heater 6 can be adjusted according to the adjustment signal exported from controller 12, To carry out increase and decrease adjustment to hot blast temperature.On this basis, control unit 29 is in the state of the thermal output increase and decrease of heater 6, energy Enough driving rotating speed of the detection signal automatically to motor 5 based on temperature sensor 25 carry out increase and decrease adjustment, and with heater 6 The change of thermal output independently keep constant hot blast temperature.
According to the air drier for possessing control unit 29 as described above, heat can be independently carried out automatically with environment temperature The adjustment of the hot blast temperature of wind drying machine.Even in addition, in user's operation controller 12, wind pushing temperature is adjusted to what is liked , can also be by detection signal automatically driving to motor 5 of the control unit 29 based on temperature sensor 25 in the case of temperature Rotating speed carries out increase and decrease adjustment, keep constant hot blast temperature.
Control unit 29 is in the case where the adjustment state of controller 12 is slow adjustment, the detection based on temperature sensor 25 The driving rotating speed that signal is performed to motor 5 carries out the normality control of increase and decrease adjustment, keep constant hot blast temperature.In this way, It is because of the thermal output of heater 6 caused by slow adjustment that normality control is carried out in the case where controller 12 is by slow adjust Amplitude of variation it is small, can reliably follow heater 6 adjustment action and with normality control definitely control motor 5 drive Turn speed.In addition, be because, if controller 12 adjustment state to be corrected control in the case of quick-adjustsing, can Suitably to control the driving rotating speed of motor 5 in the state of being acted corresponding to the adjustment of heater 6, to make from heated-air drying The temperature of the hot wind of machine supply keeps constant hot blast temperature close to target temperature.In addition, when controller 12 is readily adjusted In the case of continuing normality control, the adjustment that can not follow controller 12 acts and promptly controls the driving of motor 5 Rotating speed so that from the larger deviation target temperature of temperature of the hot wind of air drier supply.
In the case where the adjustment state of controller 12 adjusts for rapid decrease, if control unit 29 is changed to Corrective control, , then can be with the drastically decline of the thermal output of heater 6 minimize the driving rotating speed of motor 5 and drive scheduled time T1 Accordingly reduce the driving rotating speed of motor 5.Thereby, it is possible to prevent heater 6 to be absorbed in undershoot.In addition, starting correction control certainly Make and recovered to normality to control after scheduled time T1, kept constant the hot blast temperature from air drier supply.Make In the case that the driving rotating speed of motor 5 minimizes, stop supply to the driving current of motor 5, or reduce driving current The umber of pulse of pulse width and time per unit.
Controller 12 adjustment amount in order to control device 12 adjustment stroke more than 50% rapid decrease adjustment situation Under, if control unit 29 minimizes the driving rotating speed of motor 5 from normality control conversion to Corrective control, it can prevent electricity The driving of motivation 5 is rotated by unnecessarily big adjustment.If for example, adjustment stroke of the adjustment amount device 12 in order to control in controller 12 30% in the case of, be corrected control to make the driving of motor 5 rotate minimum outputization, then be used for the control of correction by Become over so that control result is significantly disperseed from target temperature.As a result, the hot blast temperature from air drier supply Stablizing to target temperature needs the time.Control unit 29 recovers to normality control from being started Corrective control after scheduled time T1 System, keep constant the hot blast temperature from air drier supply.
In the case where the adjustment state of controller 12 adjusts for quick increase, if control unit 29 is changed to Corrective control, Maximizing the driving rotating speed of motor 5 and drive scheduled time T2, then can be sharply increased with the thermal output of heater 6 Accordingly increase the driving rotating speed of motor 5.Thereby, it is possible to prevent heater 6 to be absorbed in overshoot.In addition, starting correction control certainly Make and recovered to normality to control after scheduled time T2, keep constant the hot blast temperature from air drier supply. In the case of the driving rotating speed maximum output for making motor 5, make supply maximum to the driving current of motor 5, or increase The pulse width of driving current and the umber of pulse of time per unit.
In the situation of adjustment amount more than the 50% quick increase adjustment of the adjustment stroke of device 12 in order to control of controller 12 Under, if control unit 29 maximizes the driving rotating speed of motor 5 from normality control conversion to Corrective control, it can prevent electricity The driving rotating speed of motivation 5 is by unnecessarily big adjustment.For example, adjustment amount device 12 in order to control of the time per unit in controller 12 Adjustment stroke 20% in the case of, the driving rotating speed of motor 5 is maximized if being corrected control, for correcting Control will become over so that control result is significantly disperseed from target temperature.As a result, supplied from air drier Hot blast temperature stabilization to target temperature needs the time.Control unit 29 recovers from being started Corrective control after scheduled time T2 Controlled to normality, keep constant the hot blast temperature from air drier supply.
When controller 12 is adjusted by rapid decrease, control unit 29 is changed to Corrective control turn the driving of motor 5 Speed minimizes, and when controller 12 is rapidly populated adjustment, control unit 29 is changed to Corrective control turn the driving of motor 5 Speed maximizes.According to such control mode, it can accordingly make electricity with all quick adjustment actions carried out by controller 12 The driving rotating speed of motivation 5 optimizes, keep constant the hot blast temperature from air drier supply.
The driving time T1 and controller 12 for the motor 5 being set as when controller 12 is adjusted by rapid decrease are quickly increased The driving time T2 of the motor 5 during adjustment is added to meet inequality (T1 ＜ T2) because of following reason.It is quick in controller 12 In the case of increase adjustment, the thermal output of heater 6 sharply increases.Therefore, can be by increasing the driving time of motor 5 T2, to make the temperature of the hot wind from air drier supply that close-target temperature be inscribed in the shorter time.So as to, time T1 and when Between the relation of T2 be (T1 ＜ T2).
The situation of adjustment is rapidly populated in scheduled time T1 internal controller 12 after controller 12 is adjusted by rapid decrease Under, control unit 29 controls the driving rotating speed of motor 5 because of following reason based on normality control.In controller 12 by under quick In the state of falling tone is whole, control unit 29 is temporarily switched to Corrective control minimize the driving rotating speed of motor 5.If however, Autotomy shift to after Corrective control by scheduled time T1 before quickly increase adjustment is carried out to controller 12, then must be electronic The Corrective control that the driving rotating speed of machine 5 minimizes carries out the correction in the increased direction of driving rotating speed to motor 5 before terminating Control.In this case, since the driving rotating speed of motor 5 is maximized, thus heater 6 is easily trapped into undershoot state. To prevent the problem of such, control unit 29 does not make the driving rotating speed of motor 5 maximumlly carry out based on temperature sensor 25 Detect the normality control of signal.
Situation about being adjusted after adjustment in scheduled time T2 internal controller 12 by rapid decrease is rapidly populated in controller 12 Under, control unit 29 controls the driving rotating speed of motor 5 because of following reason based on normality control.Quickly increased in controller 12 In the state of adding adjustment, control unit 29 is temporarily switched to Corrective control maximize the driving rotating speed of motor 5.If however, Autotomy shift to after Corrective control by scheduled time T2 before controller 12 adjusted by rapid decrease, then must be in motor 5 The increased Corrective control of driving rotating speed terminate before carry out to motor 5 driving rotating speed decline direction Corrective control. In this case, since the driving rotating speed of motor 5 is minimized, thus heater 6 is easily trapped into overshoot state.It is anti- The problem of only such, control unit 29 do not make the driving rotating speed of motor 5 carry out the detection based on temperature sensor 25 with minimizing The normality control of signal.
Hot blast temperature is detected by multiple temperature sensors 25, is for the temperature sensor 25 based on detection higher temperature Detection signal, the driving condition of blowing fan 4 and heater 6 is controlled by control unit 29 to improve the safety of air drier Property.
In operation mode in the state of cool wind mode switches to hot wind mode, if control unit 29 is changed to Corrective control Make the thermal output maximum output of heater 6 and drive scheduled time T3, then can steeply rise hot blast temperature extensive to shorten The multiple time to target temperature.Furthermore it is possible to recovering to normality to control after scheduled time T3, to make from air drier The hot blast temperature of supply is kept constant.
It is set as that the relation of driving time T1, T2, T3 of heater 6 meet that inequality (T1 ＞ T3 ＞ T2) is in order to prevent From cool wind mode recover to heater during hot wind mode 6 be absorbed in overshoot while, make hot blast temperature during recovery to hot wind mode Rising fast.In addition, in the case where being set as T1≤T3, the big amount of the fever time of caloric value residue heater 6, because And it is easily trapped into overshoot.In addition, in the case where being set as T3≤T2, caloric value lacks the few amount of fever time of heater 6, Hot blast temperature when thus recovering to hot wind mode becomes the time lengthening of target temperature.
If hot wind mode display body 31~34 and the adjoining configuration of cool wind mode display body 35, only have a look at each LED31 ~35 light number and the difference of glow color and can clearly judge current operating mode.
If only had a look at each adjacently close to configuration mode switching switch 9 with multiple hot wind mode display bodies 1~34 Display body 31~34 can clearly judge current operating mode.
If configuring cool wind mode display body 35 between hot wind mode display body 31~34 and mode selector switch 9, use It is cool wind mode that family, which can inerrably confirm,.Especially, the glow color of cool wind mode display body 35 is made to be shown with hot wind mode The glow color of body 31~34 significantly in the case of difference, is able to confirm that it is cool wind mode certainly.
If configuring hot wind mode display body 31~34 and cool wind mode display body 35, look at each display straight shape arranged in a straight line The situation of the lighting conditions of body 31~35 is self-evident, each display body 31~35 being mapped in visual confirmation indirectly in mirror Lighting conditions in the case of, also can clearly judge current operating mode, and do not have and wrongheaded leeway occurs.
, can be to avoid user if mode selector switch 9 and cold switch 13 are configured at the position away from shell structure Operation error or misjudgment caused by operation mode handoff error.
If configure hot wind mode display body 31~34, cool wind mode display body 35 and pattern switching in body shell 1 to open 9 are closed, and cold switch 13 is configured in handle 3, then can be grasped in the state of one hand holds handle 3 with a firm grip with the hand of empty side Operation mode switching switch 9 switches operation mode.Furthermore it is possible in the state of one hand holds handle 3 with a firm grip, change grip position, Or keep switching to hot wind mould to switch to cool wind mode, or from cool wind mode with thumb manipulation cold switch 13 with holding state with a firm grip Formula.So as to, when operator scheme switching switch 9 or cold switch 13, do not have and mistake the leeway for answering Operation switch, and can be more Reliably carry out the switching of operation mode.
If being formed temperature sensor 25 with radial lead type thermistor, and it is located at heater base in a pair of lead wires portion 25b In the state of the surface and the back side of plate 22, temperature sensor 25 is fixed on to the terminal 26 of heater substrate 22, then can use and add Hot device substrate 22 isolates a pair of lead wires portion 25b, it is thus possible to reliably prevents a pair of lead wires portion 25b from contacting and short-circuit.In addition, can With with heater substrate 22 it is strong support a pair of lead wires portion 25b, test section 25a deviates movement during reliably preventing from using.
If the leading part 25b of temperature sensor 25 is fixed on to the terminal for the intersection base portion for being arranged on heater substrate 22 26, make 23 face of heater line in test section 25a and downstream, then can definitely detect and be contacted with heater line 23 and added The temperature of hot wind after heat.
If in possessing the controller 12 of slidingtype variable resistor 39 and slide handle 40, make Elastic Sliding arm 45 and resistance Frictional resistance between wall 42 is acted on by the slide handle 40 of reciprocating operation, then slide handle 40 can be in arbitrarily adjustment position Holding is put to stop.Furthermore it is possible to by applying appropriate operation resistance to slide handle 40, it is excessive to suppress slide handle 40 Ground slide, so that operation sense during adjustment is smooth and clear.
If the resistance wall 42 at the both ends of the reciprocal stroke towards Elastic Sliding arm 45 sets increase Elastic Sliding arm 45 The friction increased portion 48 of elastic deformation amount, then can increase Elastic Sliding arm 45 in the upper and lower side of the reciprocal stroke of slide handle 40 Elastic deformation amount increase operation resistance.So that, also can be reliable in the case that slide handle 40 is by fast operating Collide the groove end of sliding groove 49 with preventing the operation portion 39a impacts of variable resistor 39 in ground.

As above-mentioned, if the LED35 adjoinings for being used in hot wind mode LED31~34 shown and being shown for cool wind mode are matched somebody with somebody Put, then that only has a look at each LED31~35 lights number and the difference of glow color, you can clearly judges current operational mode Formula.Mode selector switch 9 is configured with further, since adjacently being approached with LED31~34 shown for hot wind mode, thus Can clearly illuminating state (operation mode) of visual confirmation LED31~34 while mode selector switch 9 is switched over Operation, and can definitely carry out the switching of operation mode.Further, due to the LED31 shown for hot wind mode~ The LED35 shown for cool wind mode is configured between 34 and mode selector switch 9, and its glow color is unique blue Color, thus it is cool wind mode that user, which can inerrably confirm,.Due to LED31~34 shown for hot wind mode and for cold wind Configure the LED35 shapes arranged in a straight line that pattern is shown, thus the situation for lighting situation for looking at each LED31~35 straight is self-evident, Each LED31~35 that visual confirmation indirectly is mapped in mirror light situation in the case of, also can clearly judge Current operating mode, and do not have and wrongheaded leeway occurs.
As shown in Figure 8 and Figure 9, controller 12 possesses slidingtype variable resistor 39 and is installed on handle 3 and reciprocating operation can Become the slide handle 40 of the operation portion 39a of resistance 39.It is recessed in the front surface of handle 3 formed with sliding guidance slide handle 40 Guide part 41, sets oriented slide handle 40 to apply the resistance wall 42 of frictional resistance in the left and right of the inner surface of handle 3.Slide handle Hand 40 is integrally provided with the handle body 43 by 41 sliding guidance of guide part, the inner surface along handle 3 slides the slide 44 moved And it is formed at the Elastic Sliding arm 45 of the left and right of slide 44.It is provided with the middle part up and down of Elastic Sliding arm 45 and is being adjacent to resistance The friction protrusion 46 for going together mobile with handle body 43 in the state of wall 42.In addition, in the reciprocal punching towards Elastic Sliding arm 45 The resistance wall 42 of journey is provided with the friction portion 47 for making 45 elastic deformation of Elastic Sliding arm, and the upper and lower ends in friction portion 47 are provided with Increase the friction increased portion 48 of the elastic deformation amount of Elastic Sliding arm 45.Symbol 49 is the sliding groove of sliding guidance operation portion 39a.
When by 40 reciprocating operation variable resistor 39 of slide handle, if making the elasticity of Elastic Sliding arm 45 by friction portion 47 Deformation, applies frictional resistance to slide handle 40, then can make the operation portion 39a of variable resistor 39 in arbitrarily adjustment position Keep stopping.Furthermore it is possible to by applying appropriate operation resistance to slide handle 40, to suppress slide handle 40 by exceedingly Slide, so that operation sense during adjustment is smooth and clear.In the upper and lower side of the reciprocal stroke of Elastic Sliding arm 45, due to The elastic deformation amount of Elastic Sliding arm 45 can be increased to increase operation resistance, thus even in slide handle 40 by fast operating In the case of, collide the groove end of sliding groove 49 with being also reliably prevented from the operation portion 39a impacts of variable resistor 39.This Outside, the output of variable resistor 39 size only in the state of friction protrusion 46 is contacted with friction portion 47 is controlled by control unit 29 Change, and motor 5 in a period of rising to friction increased portion 48 from friction portion 47 in friction protrusion 46 and being moved to stroke end Driving rotating speed do not change.
(hot wind mode)
In order to which the air quantity adjustment or temperature adjustment of machine is independently automatically blowed in the change with environment temperature, to supply It is adapted to the air quantity of multiple hair treatment states and the hot wind of temperature, control unit 29 is carried out as follows operating control.If to main switch 11 Making operation is carried out, then each control circuit 5C, 6C, 15C receive the working instruction signal of control unit 29, make motor 5, heater 6th, Peltier element 15 works, and the discharge current of high pressure is supplied to sparking electrode 14.At this time, heater 6 is supplied to driving electricity With as maximum thermal output, motor 5 is driven in rotation to maintain stream with the corresponding rotating speed of output signal with controller 12 First mode.Can switch mode switching switch 9 in this condition, by the operation mode of hair-dryer switch to second mode~ Fourth mode.
For example, in the case of being intended to dry hair after hair washing, the operation mode of hair-dryer is being set to the shape of first mode Blown out under state and supply the hot wind of high temperature (100 DEG C).Become the situation of minimum speed in the driving rotating speed of the motor 5 of the state Under, since the air quantity for the hot wind for blowing out and supplying is few, thus slide handle 40 can be operated by upward Slideslip to increase electricity The driving rotating speed of motivation 5, to strengthen the air quantity of blowout and the hot wind supplied.If however, motor 5 driving rotating speed increase, The Wen Duxiajiang supply increased amounts of air quantity of hot wind.To prevent such temperature from declining, control unit 29 is based on temperature sensor 25 Detection signal automatically increase adjustment heater 6 thermal output, hot blast temperature is maintained at 100 DEG C.
As above, in embodiment 1, under 6 powered operating condition of motor 5 and heater, control unit 29 according to from The driving rotating speed for the adjustment signal adjustment motor 5 that controller 12 exports, to carry out increase and decrease adjustment to the air output of blowing fan 4. In addition, blowing fan 4 air output increase and decrease in the state of, can the detection signal based on temperature sensor 25 automatically to heating The thermal output of device 6 carries out increase and decrease adjustment (step S1~S3 in Fig. 1), and independently makes with the increase and decrease of the air output of blowing fan 4 Hot blast temperature is kept constant (following, which is referred to as normality control)., can be compared with using the temperature of the environment of hair-dryer according to season The earth changes, even if it that case, also can be by the detection signal based on temperature sensor 25 automatically to heating The thermal output of device 6 carries out increase and decrease adjustment, to make hot blast temperature be maintained at 100 DEG C of target temperature.In second mode~fourth mode Each operation mode under, control unit 29 also carries out normality control same as described above, to make the temperature of the hot wind from hair-dryer supply Degree becomes the target temperature set under each operation mode.
(slow adjustment and quick adjustment)
According to the difference regulated the speed of the controller 12 carried out by user, there is regulating the speed less than predetermined for adjustment signal The situation (following, to claim slow adjustment) of value and regulating the speed more than situation (following, the velocity modulation of expressing one's gratification of predetermined value for adjustment signal It is whole).Adjusting regulating the speed for signal can be judged by the voltage variety of the time per unit in variable resistor 39, example Such as, if the situation of the voltage variety of time per unit change 5% in every 0.1 second is predetermined value (benchmark), to judge slowly to adjust With quick adjustment.As shown in Figure 1, in the case where slide handle 40 is by slow adjust, control unit 29 carries out foregoing normality control System, target temperature is adjusted to by the hot blast temperature in each operation mode.However, situation about being readily adjusted in slide handle 40 Under, control unit 29 before after departing from normality control by the scheduled time during conversion come school to Corrective control set in advance Positive hot blast temperature, and recover to keep constant hot blast temperature to normality control after a predetermined time elapses.So-called correction control System, is that state of a control is forcibly changed to minimum output set in advance, or the setting of maximum output from normality state of a control Value, or setting value proximate to it.In Corrective control, the adjustment direction according to slide handle 40 is the side reduced, still Increased side, the mode of control are different.
(rapid decrease adjusts and quick increase adjusts)
In quick adjustment, there is the situation that slide handle 40 is rapidly operated from increase position to reduction position (below, to claim Rapid decrease adjusts) and slide handle 40 from situation (following, speed of the expressing one's gratification increasing for reducing position and rapidly being operated to increase position Add adjustment).No matter in the case of any, in the case where the adjustment amount of the time per unit of slide handle 40 is small, blowing fan 4 Driving rotation will not greatly change, thus control unit 29 maintain normality control.However, at slide handle 40 (controller 12) Adjustment amount be friction portion 47 in slide handle 40 (controller 12) adjustment stroke more than 50% quick-adjustsing feelings Under condition, control unit 29 carries out following correction to control the caloric value of heater 6.
Specifically, as shown in Fig. 1 and Figure 10, in the fast of more than 50% that the adjustment amount of slide handle 40 is adjustment stroke Speed declines in the case of adjustment (being "Yes" in the step S4 of Fig. 1), since the driving rotating speed of motor 5 drastically declines, thus send The air output of fan 4 reduces sharply, and there are the possibility that heater 6 is absorbed in overshoot (excessively rising).To avoid this phenomenon, control unit 29 exists The adjustment amount of slide handle 40 becomes more than 50% time point of adjustment stroke, from normality control conversion to Corrective control (Fig. 1 Step S5), make the minimum outputization (the step S11 of Figure 11) of thermal output of heater 6, and in process scheduled time T1 (0.8 Second) recover to control (being "Yes" in the step S13 of Figure 11) to normality afterwards.Make the control during thermal output minimum outputization of heater 6 Portion 29 processed stops supply to the driving current of heater 6, or reduces the pulse width of driving current and the arteries and veins of time per unit Rush number.When making the thermal output minimum outputization of heater 6, stop supplying to make the hot defeated of heater 6 for driving current completely It is zero (low (Low)) to go out.Alternatively, the supply for making driving current is the value close to zero, although the thermal output for making heater 6 is not zero But it is the value close to zero.For example, reducing the pulse width of driving current to make the thermal output of heater 6 close to zero, or reduce The umber of pulse of time per unit makes the thermal output of heater 6 close to zero.
It is quick adjustment in the adjustment amount of slide handle 40, and its adjustment amount is situation more than setting value set in advance Under, from normality control conversion to Corrective control.Just by slide handle 40 adjustment operation variable resistor 39 output voltage and Speech, voltage change in the range of 2V (100%) to 0V (0%).Based on this, change 1.0V in the output voltage of variable resistor 39 (50%) in the case of more than, and slide handle 40 is regulated the speed, you can becomes regulating the speed to be quick-adjustsing for resistance 39 In the case of, carry out necessary Corrective control.Specifically, time per unit every 0.1 second of voltage variety change 5% feelings Under condition, control unit 29 is determined as it being quickly to adjust, and then judges to be rapid decrease adjustment or quick increase adjustment and carry out must The Corrective control wanted.For example, in the case where the output voltage of variable resistor 39 is 1.9V, it is readily adjusted in slide handle 40 So that in the case that output voltage drops to 0.8V, control unit 29, which is determined as, to be quickly to adjust and is the tune in the direction to reduction It is whole, and from normality control conversion to Corrective control.In this way, control unit 29 is determined as it being that quick adjustment and adjustment amount meet setting More than value, and then judge adjustment direction (increase and decrease direction), and determine whether conversion to Corrective control.
The proportional relation of variable quantity of the adjustment stroke of controller 12 and the output voltage of variable resistor 39.So as to " control The adjustment stroke of device 12 " can be changed a kind of pronunciation and be pronounced " variable quantity of the output voltage of variable resistor 39 ".
It is contrary to the above, as shown in the right side of Figure 10, exceed the 50% of adjustment stroke in the adjustment amount of slide handle 40 Quick increase adjustment in the case of (being "Yes" in the step S6 of Fig. 1), since the driving rotating speed of motor 5 sharply increases, because And the air output of blowing fan 4 increases severely, the temperature there are heater 6 is absorbed in the possibility of undershoot (excessively reducing).To avoid this phenomenon, Control unit 29 exceedes 50% time point of adjustment stroke in the adjustment amount of slide handle 40, is controlled from normality control conversion to correction Make (the step S7 of Fig. 1), make the thermal output maximum output (the step S21 of Figure 12) of heater 6, and passing through scheduled time T2 (0.55 second) recovers to control (being "Yes" in the step S23 of Figure 12) to normality afterwards.Make the thermal output maximum output of heater 6 When control unit 29 be fed to the driving current of heater 6 and be set to Hi.Alternatively, driving current of the increase supply to heater 6 Pulse width and time per unit umber of pulse.Specifically, when making the thermal output maximum output of heater 6, will drive The supply of streaming current is set to Hi states, makes the thermal output of heater 6 maximum.Alternatively, the supply of driving current is set to close to most Big value, although the thermal output for making heater 6 is not the maximum state for close maximum.For example, increase the arteries and veins of driving current Width is rushed to make the thermal output of heater 6 close to Hi states, or the umber of pulse of increase time per unit makes the heat of heater 6 The close maximum of output.
As above-mentioned, if being corrected control when slide handle 40 is adjusted by rapid decrease or is rapidly populated adjustment, into And when being set as the driving of the heater 6 when the driving time T1 of the heater 6 during rapid decrease adjustment and quick increase adjust Between T2 meet inequality (T1 ＞ T2), then can reliably prevent heater 6 to be absorbed in overshoot or undershoot, to reduce relative to target The scattered amplitude of the hot blast temperature of temperature.
For the adjustment direction of the variable resistor 39 carried out by slide handle 40, selected originally from arbitrary adjustment position Side in upside (increased side) or downside (side of reduction).However, in the presence of the operation error because of user or misdeem By mistake etc., and be rapidly populated after slide handle 40 is adjusted by rapid decrease in the scheduled time T1 adjustment situation (Figure 11's It is "Yes" in step S15).In this case, as shown in figure 13, the tune of the slide handle 40 when falling tone is whole at the fast speed Whole amount exceedes 50% time point of adjustment stroke, and control unit 29 is determining soon from normality control conversion to Corrective control Speed increases the time point of adjustment, and control unit 29 departs from Corrective control and recovers to normality to control (the step S14 of Figure 11), and will add The thermal output of hot device 6 recovers to the state of normality control.Equally, in certain time after slide handle 40 is rapidly populated adjustment (being "Yes" in the step S25 of Figure 12) in the case that increase adjusts is quickly reduced in T2, the slip in quick increase adjustment The adjustment amount of handle 40 exceedes 50% time point of adjustment stroke, and control unit 29 is changed to Corrective control from normality control, and The time point of rapid decrease adjustment is being determined, control unit 29 departs from Corrective control and recovers to normality to control, and by heater 6 Thermal output recover to normality control state.
(cool wind mode)
When operating hair-dryer under the normality state of a control in arbitrary operation mode, if being connected to cold switch 13 Operation, then as shown in Fig. 6 and Figure 14, in control unit 29, the energization to heater 6 is cut off, and sends out room temperature from blow-off outlet Dry wind.Hereafter, if cold switch 13 is disconnected operation (being again switched on operating), control unit 29 is changed to Corrective control, is made The thermal output of heater 6 is changed to normality for maximum output and after driving scheduled time T3 (0.75 second) and controls and be based on temperature The thermal output of the detection signal adjustment heater 6 of sensor 25, and recover to the hot wind mode switched to before cool wind mode.Example Such as, in the case where the hot wind mode before switching to cool wind mode is second mode, recover to the state of a control of second mode To control the working status of motor 5 and heater 6.
As above-mentioned, when cold switch 13 is disconnected operation and recovers from cool wind mode to hot wind mode, if changing to school Positive control makes the thermal output maximum output of heater 6 and drives scheduled time T3, then can steeply rise hot blast temperature And shorten and recover to the time of target temperature.It is set as, the driving time T3 of the heater in Corrective control and foregoing correction The relation of the scheduled time T1, T2 in control meet inequality (T1 ＞ T3 ＞ T2).For example, it is being set as the situation of T3≤T2 Under, caloric value lacks the few amount of driving time of heater 6 so that hot blast temperature when recovering to hot wind mode reaches target temperature The time lengthening of degree, to make up such fever deficiency, is set as T3 ＞ T2.In addition, when using hair-dryer, there are suction inlet 52 are covered by towel or quilt etc. so that hot blast temperature is for example up to 120 DEG C of situation singularly.In this case, connect The control unit 29 of the output signal of shrinkage temperature sensor 25 stops the work of motor 5 and heater 6 at once, lights or extinguishes LED31~34 shown for hot wind mode and the LED35 shown for cool wind mode, to inform hair-dryer because of exception to user State and the fact that stop.The abnormal show state can be released by turning off operation to main switch 11, if right again Main switch 11 carries out making operation, then can make hair-dryer as usually working.It is used for exception in addition it is also possible in addition set The display body (LED) of display, and light and extinguish display body, to inform thing that hair-dryer stops by abnormality to user It is real.
(embodiment 2) in above-described embodiment 1, when according to driving rotating speed of the adjustment signal of controller 12 to motor 5 When carrying out size adjustment, the detection signal automatically thermal output to heater 6 based on temperature sensor 25 carries out increase and decrease adjustment, To enable hot blast temperature to keep target temperature.However, it is possible to be configured to, heater is adjusted according to the adjustment signal of controller 12 6 thermal output, to carry out increase and decrease adjustment to hot blast temperature.In this case, add when according to the adjustment signal pair of controller 12 When the thermal output of hot device 6 carries out size adjustment, control unit 29 can the detection signal based on temperature sensor 25 automatically to electricity The driving rotating speed of motivation 5 carries out increase and decrease adjustment, to make hot blast temperature keep target temperature.I.e., in example 2, control is passed through Device 12 adjust heater 6 thermal output, and based on temperature sensor 25 detection signal control motor 5 driving rotating speed this Point is different from embodiment 1, and other structures are same as Example 1.In addition, in example 2, in the control on control unit 29 Hold, in the explanation of the control content illustrated in embodiment 1, driving rotation and heating that a kind of pronunciation reads motor 5 can be changed The thermal output of device 6, thus the description thereof will be omitted.
Hair-dryer in embodiment 2 can be implemented with implementation below.A kind of hair-dryer, is provided with body shell 1 The heater 6 for the air that blowing fan 4, the motor 5 of the rotation driving blowing fan 4, heating are supplied from fan 4 and control are electronic The control unit 29 of the working status of machine 5 and heater 6.Control unit 29 receives the temperature for being used for detecting the hot wind heated by heater 6 The adjustment signal of the detection signal of the temperature sensor 25 of degree and the controller 12 of the thermal output for adjusting heater 6 simultaneously controls The driving condition of blowing fan 4 and heater 6.Further, the hair-dryer is characterized in that, the structure of control unit 29 is, Under 6 powered operating condition of motor 5 and heater, heater can be adjusted according to the adjustment signal exported from controller 12 6 thermal output, to carry out increase and decrease adjustment to hot blast temperature.In the state of the thermal output increase and decrease of heater 6, control unit 29 Driving rotating speed of the detection signal automatically to motor 5 based on temperature sensor 25 carries out increase and decrease adjustment protect hot blast temperature Hold constant.
According to the hair-dryer for possessing control unit 29 as described above, independently can be automatically blowed with environment temperature The adjustment of the hot blast temperature of machine, to supply the hot wind of the air quantity of suitable multiple hair treatment states and temperature.In addition, even in Family operates controller 12, in the case that wind pushing temperature is adjusted to the temperature liked, can also be based on temperature by control unit 29 Driving rotating speed of the detection signal of sensor 25 automatically to motor 5 carries out increase and decrease adjustment, keep constant hot blast temperature, Thus it can definitely carry out hair treatment while the hot wind of proper temperature is supplied all the time.
According to the difference regulated the speed of the controller 12 carried out by user, there is regulating the speed less than predetermined for adjustment signal Slow adjustment and the adjustment signal of value is regulated the speed more than the quick adjustment of predetermined value.Adjustment of the control unit 29 in controller 12 In the case that state is slow adjustment, the driving rotating speed that the detection signal based on temperature sensor 25 is performed to motor 5 carries out The normality control of size adjustment, keep constant hot blast temperature.In addition, control unit 29 is fast in the adjustment state of controller 12 In the case that velocity modulation is whole, control unit 29 is changed to set in advance during before departing from normality and having controlled by the scheduled time Corrective control corrects hot blast temperature, and recovers to keep constant hot blast temperature to normality control after a predetermined time elapses.
As above-mentioned, in the case where controller 12 is by slow adjust, progress normality controls, and is because caused by slow adjustment The amplitude of variation of the thermal output of heater 6 is small, can reliably follow the adjustment action of heater 6 and be controlled by normality definite Ground controls the driving rotating speed of motor 5.If in addition, be because controller 12 adjustment state in the case of quick-adjustsing into Row Corrective control, then can suitably control the driving of motor 5 to turn in the state of being acted corresponding to the adjustment of heater 6 Speed, makes the temperature from the hot wind of hair-dryer supply close to target temperature, keep constant hot blast temperature.In addition, in controller 12 continue normality control when being readily adjusted in the case that, the adjustment that can not follow controller 12 acts and controls electricity rapidly The driving rotating speed of motivation 5 so that significantly deviate from target temperature from the temperature of the hot wind of hair-dryer supply.
When the side that the thermal output that controller 12 is adjusted to heater 6 from arbitrary adjustment position declines, controlling In the case that the adjustment state of device 12 is rapid decrease adjustment, control unit 29 is changed to Corrective control, to make the driving of motor 5 Rotating speed minimizes, and is recovering to normality to control after scheduled time T1.
As above-mentioned, in the case where the adjustment state of controller 12 adjusts for rapid decrease, if control unit 29 is changed to school Positive control, minimizes the driving rotating speed of drive motor 5 and drives scheduled time T1, then can be with the thermal output of heater 6 Drastically reduce accordingly reduce motor 5 driving rotating speed.Thereby, it is possible to prevent heater 6 to be absorbed in undershoot.In addition, from Start Corrective control to recover to normality to control after scheduled time T1, the hot blast temperature supply hair-dryer keeps perseverance It is fixed.
Controller 12 adjustment amount in order to control device 12 adjustment stroke more than 50% rapid decrease adjustment situation Under, control unit 29 is recovering to normality to control from normality control conversion to Corrective control after scheduled time T1.
As above-mentioned, in more than the 50% rapid decrease adjustment of the adjustment amount adjustment stroke of device 12 in order to control of controller 12 In the case of, can be with if control unit 29 minimizes the driving rotating speed of motor 5 from normality control conversion to Corrective control The driving for eliminating motor 5 is rotated by unnecessarily big adjustment.For example, the adjustment of the adjustment amount device 12 in order to control in controller 12 In the case of the 30% of stroke, if being corrected control to make the driving of motor 5 rotate minimum outputization, it is used for what is corrected Control will become over so that control result is significantly disperseed from target temperature.As a result, the hot wind temperature from hair-dryer supply Degree, which is stablized to target temperature, needs the time.Control unit 29 recovers to normality from being started Corrective control after scheduled time T1 Control, keep constant the hot blast temperature from hair-dryer supply.
When the increased side of the thermal output that controller 12 is adjusted to heater 6 from arbitrary adjustment position, controlling In the case that the adjustment state of device 12 is quick increase adjustment, control unit 29 is changed to Corrective control, turns the driving of motor 5 Speed maximizes, and is recovering to normality to control after scheduled time T2.
As above-mentioned, in the case where the adjustment state of controller 12 adjusts for quick increase, if control unit 29 can be changed , then can be hot defeated with heater 6 maximize the driving rotating speed of motor 5 and drive scheduled time T2 to Corrective control The increase drastically gone out accordingly increases the driving rotating speed of motor 5.Thus, it is possible to heater 6 is prevented to be absorbed in overshoot.In addition, Recovering to normality to control after scheduled time T2 from being started Corrective control, protect the hot blast temperature from hair-dryer supply Hold constant.
In the case of 50% quick increase adjustment of the adjustment stroke that the adjustment amount of controller 12 exceedes controller 12, Control unit 29 is changed to Corrective control, and is recovering to normality to control after scheduled time T2.
As above-mentioned, in more than 50% quick increase adjustment of the adjustment amount adjustment stroke of device 12 in order to control of controller 12 In the case of, can if control unit 29 maximizes the driving rotating speed of motor 5 from normality control conversion to Corrective control The driving rotating speed of motor 5 is eliminated by unnecessarily big adjustment.For example, the adjustment amount in the time per unit of controller 12 is control In the case of the 20% of the adjustment stroke of device 12 processed, if being corrected control maximize the driving rotating speed of motor 5, use It will be become in the control of correction so that control result is significantly disperseed from target temperature.As a result, supplied from hair-dryer Hot blast temperature stabilization to target temperature need the time.Control unit 29 from being started Corrective control after scheduled time T2 it is extensive Controlled again to normality, keep constant the hot blast temperature from hair-dryer supply.
When the side that the thermal output that controller 12 is adjusted to heater 6 from arbitrary adjustment position declines, controlling In the case that the adjustment state of device 12 is rapid decrease adjustment, control unit 29 is changed to Corrective control, to make the driving of motor 5 Rotating speed minimizes, and recovers to normality to control after scheduled time T1.When controller 12 from arbitrary adjustment position adjustment to During the increased side of the thermal output of heater 6, controller 12 adjustment state for quick increase adjustment in the case of, control unit 29 conversions maximize the driving rotating speed of motor 5, and are recovering to normality control to Corrective control after scheduled time T2 System.
As above-mentioned, when controller 12 is adjusted by rapid decrease, control unit 29 is changed to Corrective control to make motor 5 Rotating speed is driven to minimize, when controller 12 is rapidly populated adjustment, control unit 29 is changed to Corrective control to make motor 5 Rotating speed is driven to maximize., can be corresponding with all quick adjustment actions carried out by controller 12 according to such control mode Ground optimizes the driving rotating speed of motor 5, keep constant the hot blast temperature from hair-dryer supply.
It is set as, the driving time T1 of the motor 5 when the adjustment state of controller 12 adjusts for rapid decrease and control The driving time T2 of motor 5 when the adjustment state of device 12 adjusts for quick increase meets inequality (T1 ＜ T2).
It is such as above-mentioned, it is set as, the driving time T1 and controller 12 of the motor 5 when controller 12 is adjusted by rapid decrease The driving time T2 of motor 5 when being rapidly populated adjustment meets inequality (T1 ＜ T2) because of following reason.In controller In the case that 12 are rapidly populated adjustment, the thermal output of heater 6 sharply increases.Therefore, can be by increasing the drive of motor 5 Dynamic time T2, to make the temperature of the hot wind from air drier supply that close-target temperature be inscribed in the shorter time.So as to the time The relation of T1 and time T2 are (T1 ＜ T2).
The situation of adjustment is rapidly populated in scheduled time T1 internal controller 12 after controller 12 is adjusted by rapid decrease Under, control unit 29 controls the driving rotating speed of motor 5 based on normality control.
It is such as above-mentioned, after controller 12 is adjusted by rapid decrease adjustment is rapidly populated in scheduled time T1 internal controller 12 In the case of, control unit 29 controls the driving rotating speed of motor 5 because of following reason based on normality control.In 12 quilt of controller In the state of rapid decrease adjustment, temporarily conversion minimizes the driving rotating speed of motor 5 to control unit 29 to Corrective control.So And if autotomy shift to after Corrective control by scheduled time T1 before controller 12 be rapidly populated adjustment, must tie The school in the increased direction of driving rotating speed to motor 5 is carried out before the Corrective control that the driving rotating speed of beam motor 5 minimizes Positive control.In this case, since the driving rotating speed of motor 5 is maximized, thus heater 6 is easily trapped into undershoot shape State.To prevent the problem of such, control unit 29 does not make the driving rotating speed of motor 5 maximumlly carry out being based on temperature sensor 25 Detection signal normality control.
In the case where rapid decrease adjusts controller 12 in certain time interval T 2 after controller 12 is rapidly populated adjustment, Control unit 29 controls the driving rotating speed of motor 5 based on normality control.
As above-mentioned, after controller 12 is rapidly populated adjustment, in scheduled time T2 internal controller 12 by rapid decrease tune In the case of whole, control unit 29 controls the driving rotating speed of motor 5 because of following reason based on normality control.In controller 12 It is rapidly populated in the state of adjustment, control unit 29 is temporarily switched to Corrective control maximize the driving rotating speed of motor 5. If however, autotomy shift to after Corrective control by scheduled time T2 before controller 12 adjusted by rapid decrease, must be The school in the direction that the driving rotating speed to motor 5 declines is carried out before terminating the increased Corrective control of driving rotating speed of motor 5 Positive control.In this case, since the driving rotating speed of motor 5 is minimized, thus heater 6 is easily trapped into overshoot shape State.To prevent the problem of such, control unit 29 does not make the driving rotating speed of motor 5 carry out with minimizing being based on temperature sensor 25 Detection signal normality control.
In the above-described embodiments, controller 12 is formed using slidingtype variable resistor 39, but without this manner it is also possible to make Controller 12 is formed with dial-type variable resistor.In the above-described embodiments, situation of the blowing fan 4 for axial-flow type fan is carried out Illustrate, but without in this way, blowing fan 4 can also be turbine fan or multiple-blade fan.In addition, hair-dryer needs not to be hand-held blow Machine or desk-top hair-dryer.So-called air drier is in addition to hair-dryer, further includes the drying for foot The concept of machine, the drying machine for finger, the drying machine for first portion, the drying machine for animal etc..
In Corrective control in embodiment 1, state of a control is forced from normality state of a control when falling tone is whole at the fast speed Ground changes to the setting value of minimum output set in advance or setting value proximate to it, but without such.For example, set in advance Fixed minimum output can also be set to the thermal output of the half of Hi states.That is, so-called minimum outputization, is by thermal output It is reduced to the setting value of minimum thermal output set in advance or the setting value close to it, it is not necessary that be defined in zero or near zero Value.Equally, state of a control is forcibly changed into maximum set in advance from normality state of a control in quick increase adjustment The setting value of output or the setting value close to it, but without such.For example, minimum output set in advance can also be set For the thermal output of the half of Hi states.That is, so-called minimum outputization is to improve thermal output to maximum heat set in advance The setting value of output or the setting value close to it, it is not necessary that be defined in Hi states or the value close to it.
