Description

  The present invention relates to a dryer that emits negative ions while sending hot air and cold air, and more particularly to a dryer that controls heating by a heater unit during hot air operation.

  As a background art of the dryer of the present invention, there is a dryer disclosed in Japanese Patent Application Laid-Open No. 2004-208935. The background art dryer will be described below.

The dryer of this background art has a hot air flow path for blowing hot air to discharge hot air to the hair, and a cold air flow path for blowing cool air to discharge cold air to the hair, and at the same time hot air and cold air It has a mode for blowing air, and includes an ion generator that discharges negative ions in the same direction as the air blown through the flow path.

It has the effect of allowing hair to be moistened and smooth.
JP 2004-208935 A

  Since the dryer according to the background art is configured as described above, the warm air sent from the hot air flow path is adjacent to the warm air sent from the hot air flow path and the cold air sent from the cold air flow path. Cold air with negative ions sent from the cold air flow path is heated, and the negative ions receive energy and evaporate before reaching the user's hair, or have high energy even when they reach the user's hair. Therefore, there is a problem that it is easy to evaporate and sufficient hair gloss, moist feeling and smooth feeling cannot be obtained.

  Moreover, it has the subject that a negative ion cannot be supplied with respect to the part which should receive a cold wind by hand shake of a user. Although it is conceivable for the user to consciously apply negative ions to the target site, the delivery range of negative ions varies depending on the distance from the nozzle and the air volume, and it is difficult to perform by user operation Have This is because cold air and hot air are sent simultaneously.

  Moreover, since the cool air flow path is structurally formed, there is a problem that it is impossible to send only warm air from which no cool air is sent. Some users may want to use only warm air to dry after hair washing.

  An object of the present invention is to provide a dryer that suppresses heating of cold air accompanied by negative ions and can receive a sufficient supply of negative ions by anyone without depending on user operations. . It is another object of the present invention to provide a dryer having a mode capable of delivering only warm air that does not deliver cold air while achieving the object.

  A dryer according to the present invention includes a blower fan that generates wind, a motor that rotationally drives the blower fan, a heater unit that heats the generated wind, and a discharge unit that generates ions when a high voltage is applied. The heating by the heater unit is intermittently performed while the discharge means is being driven. Thus, according to the dryer according to the present invention, the heater unit performs heating intermittently while the discharge means is being driven, so that negative ions generated by the discharge means are not generated during the intermittent heating period of the heater unit. Without receiving energy from the hot air and evaporating it, it is sent while the hot air or cold air is switched, so even if the user does not pay special attention to the operation, sufficient negative ions are supplied to the hair, the hair is glossy, moist There is an effect that the hair can be dried or styled so as to have a feeling of smoothness.

  In addition, the dryer according to the present invention is configured so that the motor is driven to rotate and a high voltage is applied to the discharge unit when the operation mechanism is operated, and then the rotation drive and discharge unit of the motor are rotated. The heater unit heats the wind behind the discharge. As described above, according to the dryer according to the present invention, since the rotation of the motor is started and the discharge of the discharge unit is started, the heating of the heater unit is started after a lapse of a predetermined time, so that the wind is sent from the dryer. For the first time, only cold air with negative ions generated by the discharge means is sent out for a predetermined time, and a large amount of negative ions is supplied to the user's hair to firmly penetrate the hair, and after the penetration of the negative ions, the heater unit The effect is that warm air is sent out and hair can be dressed. The start time of the predetermined time elapses depends on what is used as a reference, and when detecting the time when the operating mechanism is operated, this is the time when it is detected, and when detecting the switch state of the switch in the circuit Is the time of detection, and depends on the method for obtaining the start time.

  In addition, the dryer according to the present invention has a time from the rotational drive of the motor or the discharge start of the discharge means to the heating of the heater unit shorter than the heating stop period of the intermittent period of heating by the heater unit, if necessary. It is. Thus, according to the dryer of the present invention, the time from when the motor starts to rotate until the heater unit is heated, or the time from when the discharge means starts to discharge until the heater unit is heated is Since it is shorter than the heating stop period when the unit heats intermittently, a large amount of negative ions will be generated by the user's hair by using cold air instead of hot air continuously immediately after the start of air delivery from the dryer. If only such cold air is continued, it will be charged with negative ions and will negatively affect the supply of negative ions, and the user will not be able to adjust hair or dry by not switching to warm air moderately The situation can be avoided and, in particular, the user's anxiety or dissatisfaction because it is shorter than the heating stop period of the intermittent heating period of the heater unit. An effect that can be suppressed.

  Further, in the dryer according to the present invention, when the operation mechanism is operated, the motor is driven to rotate and a high voltage is applied to the discharge means, and the heater unit heats the wind as necessary. The heating period at the start of heating by the heater unit is longer than the heating period of the intermittent heating period by the heater unit. As described above, according to the present invention, the operation of the operation mechanism starts the rotation of the motor, the application of voltage to the discharge means, and the heating of the heater unit. Since it is longer than the heating period in the case of intermittent heating, normal warm air is sent out by rotating the motor, applying voltage to the discharge means, and starting the heating of the heater unit. Dry, make it easy for negative ions to adhere, supply cold air with negative ions and let it adhere to the dried hair, making it easier for negative ions to penetrate, glossing the hair, moistening the hair, and smooth It has the effect that it can be done. The hair after washing is certainly wet and appears to have water retention, but unlike negative ions, the water mass is large and does not reach the cortex and pulp of the hair, so the water retention after drying the hair Inferior to Therefore, the negative ions are smoothly supplied by drying the hair at one end and making the hair positively charged. Moreover, even if it is not after shampooing and humidity is high, it acts similarly.

  The dryer according to the present invention intermittently applies voltage to the discharge means as necessary. As described above, according to the present invention, not only the heating of the heater unit is intermittently performed, but also the voltage application to the discharging means is intermittently performed, so there is a heating stop period of an intermittent cycle of heating of the heater unit. Therefore, it is possible to avoid a situation in which a large amount of negative ions generated by the discharge means are supplied and excessively charged and the negative negative ions are wasted, and it is efficient without supplying an appropriate amount of negative ions and charging. This has the effect of allowing negative ions to penetrate into the hair. More specifically, the oversupply of negative ions means that the negative ions overlap with the hair to which negative ions have already adhered, and the negative ions on the surface layer are excessive so that they do not reach the hair. In the end, the negative ions in the surface layer part gain energy from the air at normal temperature and evaporate away from the hair.

  In addition, the dryer according to the present invention does not apply the voltage of the discharge means in the whole period or a part of the heating period of the intermittent period of heating by the heater unit, if necessary, and intermittent period of heating by the heater unit. The voltage application of the discharge means is performed during the entire period or a part of the heating stop period. Thus, according to the dryer according to the present invention, the intermittent heating by the heater unit has a heating period and a heating stop period, and charging by the excessive negative ions without applying voltage of the discharging means in the former heating period. In the latter heating stop period, energy is given to water molecules by warm air to evaporate it and evaporate it to separate unnecessary negative ions (the negative ions that have already penetrated the hair do not evaporate with warm air). By applying a voltage to the discharge means and supplying a large amount of negative ions to the hair that is easily attached by the warm air, unnecessary negative ions are not generated and an efficient operation can be performed. It has the effect. Here, it is desirable to apply the voltage of the discharging means during the entire heating period and not to apply the voltage of the discharging means during the entire heating stop period. Even if the voltage application of the discharge means is not performed during a part of the heating stop period, some effects can be obtained.

  In addition, the dryer according to the present invention includes a heater unit notifying unit that performs at least one of light emission, sound generation, and vibration during a heating period of the heater unit as necessary. Thus, according to the dryer according to the present invention, the heater unit notification means is provided, and the heater unit notification means notifies in the heating period of the intermittent heating period of the heater unit and the heating period other than the intermittent period. In addition to confirming hot air and cold air by bodily sensation, the user can additionally confirm the heating period by at least one of visual, auditory, and tactile sensations. If hot air is sent directly to the skin, the user will immediately notice, but if it is sent only to the hair, the hair has no temperature sensory function, so it takes time to notice that it has switched to hot air. Therefore, the presence of the light emitting means makes it possible to quickly notice the change to hot air and to properly use the dryer. Unlike warm air, the vibration is transmitted to the hand holding the dryer, so the user can recognize it reliably.

  In addition, the dryer according to the present invention includes a discharging means notifying means for performing at least one of light emission, sound generation, and vibration during the voltage application period of the discharging means as required. Thus, according to the dryer according to the present invention, the discharging means notifying means is provided, and the discharging means notifying means notifies during the voltage application period of the discharging means, so that the user visually confirms the heating period. In addition, the discharge period can be additionally confirmed by at least one of visual, auditory, and tactile sensations. In particular, even during the discharge period, a person can experience a negative ion release. Since it cannot be used, it has the effect that it can be efficiently used after knowing that negative ions are released through visual, auditory, and tactile sensations.

  Further, in the dryer according to the present invention, if necessary, the heater unit notifying means and the discharging means notifying means disposed in the wind tunnel portion suck air in order to generate air by the blower fan. It emits light toward. As described above, according to the dryer according to the present invention, the heater unit notification means and the discharge means notification means emit light toward the suction port side. In many cases, the suction port side is reflected in the mirror in such a use, and the user can surely visually recognize the suction port by providing a light emitting device among the notification means. It has the effect that it can be convenient.

A dryer according to a first embodiment of the present invention will be described with reference to FIGS. 1 is a cross-sectional view of a dryer according to the present embodiment, FIG. 2 is a cross-sectional explanatory view and an enlarged view of a main part of the dryer according to the present embodiment, FIG. 3 is a circuit diagram of the dryer according to the present embodiment, and FIG. It is a timing chart of the dryer which concerns on a form.
In each of the drawings, the dryer according to the present embodiment includes a blower fan 1 that generates wind, a motor 10 that rotationally drives the blower fan 1, a heater unit 20 that heats the generated wind, and ions when a high voltage is applied. And a discharge unit 50 that generates heat, and the heater unit 20 intermittently heats the discharge unit 50 while the discharge unit 50 is driven.

  As shown in FIG. 1, a nozzle 3 for rectifying warm air sent from the air outlet 2 is disposed at the tip of the air outlet 2, and a heater unit is provided in the case main body 30 that forms the air outlet 2 and the wind tunnel portion 31. 20, the motor 10 and the blower fan 1 are provided, and the suction port 4 connected to the rear portion of the case body 30 is formed in a mesh shape so that air can flow into the fan 1. A slide knob 41 that is slidable in the vertical direction is disposed on the front surface of the grip 40 pivoted on the bottom portion of the case body 30 near the suction port 2. The grip 40 part tilts toward the case body 30 around the pivot and can be folded. One end of the power cord 5 is inserted into the bottom portion of the grip 40 and is electrically connected to the heater wire 21, the motor 10, and the discharge means 50 through an electronic circuit inside the grip 40.

  The heater unit 20 includes a heater wire 21 for converting electricity into heat, and a heater base frame 22 made of mica (mica) in which the heater wire 21 is arranged in a spiral shape. The heater base frame 22 around which the heater wire 21 is wound is fitted and fixed in a plurality of grooves in the longitudinal direction of the wind tunnel portion 31 formed on the inner surface of the case main body 30 formed in a cylindrical shape with heat-resistant plastic. Yes. In addition to the heater wire 21 and the heater base frame 22, a discharge means 50 including a discharge electrode 51, a transformer 52 and a pulse generation circuit 53 is built in the case body 30. The discharge means 50 is driven at each slide position in the second stage, the second stage, and the third stage to generate negative ions, and the wind is generated by the rotation of the blower fan 1 driven by the motor 10 to cool air from the air outlet 2 or Negative ions are released with warm air. Here, a cylindrical metal heat insulator is disposed between the case body 30 and the heater base frame 22, and the case body 30 is prevented from being heated by the heat insulator, and is locally generated by heat conduction. Heat can be prevented and radiant heat can be reflected.

  As shown in FIG. 2, the discharge means 50 includes a discharge electrode 51, a transformer 52, and a pulse generation circuit 53 that are built in the periphery of the air outlet 2 of the case body 30, and generates negative ions. . Specifically, an insulating member 54 is formed around the needle-shaped discharge electrode 51, and a counter electrode 55 of the discharge electrode 51 is disposed around the insulating member 54. 55 is in a separated state. Furthermore, a cylindrical insulating tube 56 is formed at the tip of the discharge electrode 51, and, like the insulating member 54, prevents spark discharge caused by a large current with the counter electrode 55, and is about 1 to 100 [μm]. The corona discharge in the gas is realized by generating a small current. Corona discharge occurs between the discharge electrode 51 and the counter electrode 55 along the insulating cylinder 56, a large amount of electrons are emitted, and the wind generated by the rotation of the blower fan 1 passes through the wind tunnel 31. Oxygen and electrons collide, and oxygen is negatively ionized and released from the tip of the nozzle 3. By covering the needle-like discharge electrode 51 with the insulating cylinder 56 in this manner, corona discharge is uniformly generated and oxygen is not ozonized, and the life of the discharge electrode 51 can be increased.

  A slide knob 41 is slidable on the grip 40 and can be switched in three stages except for the OFF state. When the slide knob 41 is slid in the first stage, the air is not blown, and negative ions are released. When the slide knob 41 is slid to the second stage, the warm air is in a small warm air state with a small air volume, and negative ions are released. When the slide knob 41 is slid to the third stage, the hot air is in a large hot air state with a large air volume, and negative ions are released.

  In the circuit diagram, as shown in FIG. 3, a first switch 62 that opens and closes by the sliding operation of the slide knob 41 is connected in series to the AC power supply 61. The first switch 62 is connected in series with a diode 63, and a second switch 64 that opens and closes by sliding the slide knob 41 is connected in parallel to the diode 63. The diode 63 is connected to a diode bridge 65 that performs full-wave rectification, the motor 10 is connected to the diode bridge 65, and a smoothing capacitor 66 is connected to the motor 10. The diode bridge 65 is connected to the AC power supply 61 via a high temperature prevention fuse 67 and a resistor 68.

  The first switch 62 is connected in series with a third switch 69 that opens and closes by a sliding operation of the slide knob 41. The third switch 69 is connected in series with a diode 70 that performs half-wave rectification, and a fourth switch 71 that opens and closes by a sliding operation of the slide knob 41 is connected in parallel to the diode 70. A thermo switch 72 for preventing high temperature is connected in series to the diode 70 from the viewpoint of safety. The heater wire 21 is connected in series to the thermo switch 72 via a fifth switch 73. The fifth switch 73 is switched by the heater control circuit 74. The heater control circuit 74 is connected to the first switch 62 via the step-down circuit 75 that lowers the applied voltage and receives supply of current from the AC power supply 61.

  A resistor 76 and a light emitting diode 77 are connected in parallel with the heater wire 21, and the light emitting diode 77 is lit whenever the heater wire 21 is conductive. The heater wire 21 is connected to the AC power supply 61 through a fuse 78 that prevents the temperature from rising. Here, the light emitting diode 77 is used as the light emitting means. In addition, various light bulbs such as an incandescent light bulb and a halogen light bulb, various light emitting elements other than the light emitting diode (electroluminescence), and various lasers such as a semiconductor laser are used. be able to.

  A sixth switch 79 is also connected in series to the first switch 62. The sixth switch 79 is connected to the rectifier circuit 80 and supplies the rectified current to the pulse generation circuit 53 connected in series. The pulse generation circuit 53 generates a pulse from the supplied current and supplies the pulse to the transformer 52. The transformer 52 transforms the pulse to a voltage necessary for corona discharge, and applies the transformed voltage to the discharge electrode 51 and the counter electrode 55. As the rectifier circuit 80, for example, a half-wave rectifier circuit can be formed with a diode and a resistor, and a capacitor that smoothes the pulsating voltage after half-wave rectification can be connected. As the pulse generation circuit 53, a primary side coil of a transformer 52 and a capacitor are connected in series, and only when a predetermined voltage is applied in parallel with the primary side coil of the transformer 52, a side-switch is maintained. There is something connected. In this way, after the voltage is applied to the capacitor and reaches the predetermined voltage, the Sidac is turned on to release the charge accumulated in the capacitor, and when the voltage drops below the predetermined voltage, the Sidac is opened. A pulse waveform is output by repeating a series of operations in which electric charges are accumulated. In addition to the pulse oscillation circuit 53, a pulse oscillation circuit using a generally used crystal oscillator and a pulse oscillation circuit using a plurality of flip-flops can be used. In order to obtain a necessary pulse, a frequency divider is appropriately used.

  The heater control circuit 74 outputs a control signal to switch the fifth switch 73 made of a semiconductor element such as a power transistor or a thyristor. The heater control circuit 74 outputs a control signal corresponding to the slide position of the slide knob 41. When the slide knob 41 is in the first stage, the heater control circuit 74 does not output a control signal. This is because the third switch 69 is not turned on, so that the heater wire 21 is not conducted and the fifth switch 73 does not need to be switched. When the slide knob 41 is in the second and third stages, the heater control circuit 74 outputs a control signal having a cycle of 0.1 seconds or more as shown in FIG. 4, and the fifth switch 73 also outputs this control signal. In accordance with the control signal, the on state and the open state are repeated every cycle of 0.1 seconds or longer, and conduction and non-conduction to the heater wire 21 are repeated. The heater control circuit 74 determines which slide position the slide knob 41 is currently in by a micro switch (not shown). A mechanical switch other than a micro switch may be used, or the current slide position of the slide knob 41 may be determined using a proximity switch, a photoelectric switch, or a reed switch. In addition, as a method for the heater control circuit 74 to determine the slide position of the slide knob 41, there is a method of determining from the circuit, and the switch state of each switch changes according to the slide position of the slide knob 41. Such a switch state can also be detected by outputting it to the heater control circuit. Furthermore, the slide position of the slide knob 41 can be indirectly determined not only by the switch state of the switch but also by detecting the voltage level of the wire line whose voltage level changes with the switch.

  In the output signal of the heater control circuit 74, the time from time (t1-2) to time (t1-4) in FIG. 4 is one cycle of the output cycle, and the time from time (t1-2) to time (t1-3). This is the output period, and the output stop period is from time (t1-3) to time (t1-4). In addition, in the heater wire 21, the period from time (t1-2) to time (t1-4) in FIG. 4 is one cycle of the intermittent period, and the period from time (t1-2) to time (t1-3) is heated. The period from time (t1-3) to time (t1-4) is the heating stop period. For example, one period of the intermittent period may be 8 [seconds], the heating period may be 4 [seconds], and the heating stop period may be 4 [seconds]. The time shown here is an example, and any time setting can be performed. However, when the period and time are less than 0.1 [seconds], the temperature in the wind tunnel portion 31 may sufficiently decrease. Since it is not possible and appropriate cool air cannot be sent out, it is desirable that the set time is 0.1 [second] or more. Further, the usage time of the dryer varies depending on the length and quality of the user's hair, but if the period and time are 10 [min] or more, there are not a few users who finish using the dryer. Since there may be cases where the operation specific to the dryer according to this embodiment may not be received, the period and time to be set are preferably less than 10 [minutes]. Furthermore, a general user does not dry a predetermined part of the head intensively and dry other parts, but does not rotate each part evenly, but the whole part is dried (dry locally). And the scalp becomes hot, and the hair itself is also damaged), and the time to go through each part varies depending on the hair quality of the user, the length of the hair, etc., but it is about several tens of seconds to several minutes, It is more preferable that this time is an intermittent period, a heating period, and a heating stop period. By using each part in accordance with the time to pass through, use the first time to dry, the second time to penetrate negative ions, the third time to dry, the fourth time to penetrate negative ions, and so on. Can do. In the case of such use, it is preferable that the heating period and the heating stop period are approximately the same as shown in FIG. In FIG. 4, the output waveform of the control signal of the heater control circuit 74 and the output waveform of the heater wire 11 are completely synchronized (the voltage levels are different), but the heater wire 11 as shown in FIG. 4 is intermittent. As long as the output waveform can be obtained (not limited to the pulse wave), the output waveform of the control signal of the heater control circuit 74 may be any form. For example, the output period and the output stop period of the heater control circuit 74 are The trigger signal may be sufficiently smaller than the heating period and heating stop period of the heater wire 11. That is, the switching state of the fifth switch 73 changes every time the trigger signal is output, and the output period of the trigger signal and the output stop period itself are not directly involved in switching.

  FIG. 2A illustrates the relationship between the dryer according to the present embodiment and circuit element elements (especially switches) with the connection state of the conductive lines. The slide knob of FIG. The dotted line extending from 41 does not limit the knife switch, but indicates that each switch is switched by the slide of the slide knob 41. The dotted line extending from the heater control circuit 74 indicates the same thing.

  Further, as shown in FIG. 4, the slide knob 41 is slid at time (t1-1), and the heater wire 11 is not conducted although the motor 10 is in the driving state. It is not the output period of the control signal of the control circuit 74, but is finally the output period at time (t1-2). In other words, when the slide knob 41 as the operation mechanism is operated, the motor 10 is driven to rotate, and a high voltage is applied to the discharge electrode 51 constituting the discharge means 50, and then the wind generated by the heater unit 20 is heated behind the rotation of the motor 10 and the discharge of the discharge electrode 51. It is the structure to do. The user's hair is free of negative ions before using the dryer, and is charged positively in the dry state. Therefore, immediately after the start of use of the dryer, the negative ions are not charged on the user's hair, and the negative ions released from the dryer are well attached and penetrated. In particular, when styling rather than drying the hair, it is desirable to release negative ions to the user in a cold air state without heating the air generated by the heater unit 20. The heater control circuit 74 detects that the slide knob 41 has been slid in the second stage or the third stage by the micro switch, and sets the detected time as a time (t1-1), and a timer from the time (t1-1). When a predetermined time has passed, the control signal for the output period is automatically output instead of manually at time (t1-2). As the timer, a combination of a capacitor and a resistor, a timer using a semiconductor element, or the like can be used. This timer may be inside the heater control circuit 74 or outside the heater control circuit 74.

  Furthermore, in FIG. 4, the heating start waiting time from time (t1-1) to time (t1-2) is shorter than the heating stop period of the heater wire 11, in other words, the motor 10 The time from the start of rotational driving until the heater unit 20 is heated is shorter than the heating stop period when the heater unit 20 heats intermittently. When one period of the intermittent period is exemplified as 8 [seconds], the heating start standby time can be set to 2 [seconds], for example. Also here, for the same reason as the intermittent period, the heating period, and the heating stop period, the heating start standby time is preferably 0.1 [second] to 10 [minute]. If the user slides the slide knob to the second or third stage and naturally expects the hot air to come out, but the hot air is not continued immediately after the start, Even if the user recognizes that the operation is a dryer to which the present invention is applied, the cold air is continuously sent out when drying. If the heating start standby time is set to a time shorter than the heating stop period of the heater wire 11 as shown in FIG. Thus, sufficient negative ions can be received immediately after the start.

  Since the resistor 76 and the light emitting diode 77 are connected in parallel to the heater wire 21, when a current flows through the heater wire 21, a small current flows through the resistor 76, and also flows through the light emitting diode 77 to emit light. That is, as the heater wire 21 is heated, the light emitting diode 77 also emits light. If there is no switching control of the fifth switch 73 by the heater control circuit 74, the heater control circuit 74 does not have a special effect because it emits light continuously in the small warm air mode and the large warm air mode. 5 switch 73 is switched, voltage application to the heater wire 21 is intermittent, and the air sent out from the air outlet 2 is alternately sent out between warm air and cold air, so the light emission of the light emitting diode 77 is also lit. In addition to being able to experience not only the warm air and the cold air being sent out, but the user can also visually recognize it, and the user changes the nozzle 3 direction according to the experience or visual recognition. can do. That is, the user recognizes that a large amount of negative ions is released in the case of cold air, and that negative ions are released in the case of hot air, but does not evaporate and settle on the hair. The nozzle 3 tip can be directed to a portion to which negative ions are supplied, and the tip of the nozzle 3 can be directed to a portion that is desired to be dried in hair or a portion that is desired to be hair-styled during warm air. In this case, there is a slight time lag in the temperature sensation because the heater wire 21 is heated, the wind is heated, the wind is sent out from the outlet 2, and the warm air is felt by the skin. If the light emitting diode 77 is caused to emit light together with the conduction, the notification can be made almost simultaneously, and the user can change the direction of the nozzle tip of the dryer more smoothly.

  As shown in FIG. 1, the slide knob 42, which is an intermittent state switching means for determining whether or not voltage is intermittently applied to the heater wire 21 in the small warm air mode and the large warm air mode, is provided on the grip 40. The switch 43 connected to the fifth switch 73 is turned on by sliding the slide knob 42 to the upper side, provided on the back side, and in the small warm air mode and the large warm air mode. A voltage is not applied intermittently to the heater wire 21 and a voltage is continuously applied, and thus hot air is continuously sent out. Conversely, by sliding the slide knob 42 downward, a voltage is intermittently applied to the heater wire 21 in the small warm air mode and the large warm air mode. By providing such a slide knob 42, a user who wants to receive an intermittent operation capable of effectively supplying negative ions after drying and styling hair intensively without cold air. It can meet the demands of complex users. Here, it is assumed that the switching operation of the fifth switch 73 does not affect the current supply to the heater wire 21 because the switch 43 is turned on. A similar current supply to the heater wire 21 can also be realized by the heater control circuit 74 that controls the slide knob 42 discriminating the slide position of the slide knob 42 with a micro switch or the like and determining whether or not a control signal is output. .

  Next, the operation of using the dryer according to this embodiment will be described. The user pushes the slide knob 41 into the first stage after inserting the power plug 6 into a power outlet (not shown). Then, the first switch 62, the second switch 64, and the sixth switch 79 are turned on, and the current from the AC power supply 61 is supplied to the diode bridge 65 via the second switch 64 and is full-wave rectified. Then, the air is smoothed by the condenser 66 and supplied to the motor 10, the motor 10 is driven, the fan 1 rotates, the outside air is taken in from the suction port 4, and the air compressed by the blades passes through the wind tunnel portion 31 and is in the blowing mode. Wind is sent out from the outlet 2. Since the third switch 69 is not turned on, power is not supplied to the heater unit 20 and the heater unit 20 is not heated. However, since the sixth switch 79 is turned on, the current rectified by the rectifier circuit 80 is converted into the pulse generation circuit 53. Then, a pulse is generated in the pulse generation circuit 53 and boosted by the transformer 52, and then a voltage of about −4 [kV] is applied to the discharge electrode 51 to cause corona discharge together with the counter electrode 55. Therefore, oxygen molecules in the wind generated by the fan 1 collide with electrons in the corona discharge and further combine with water molecules to be discharged as negative ions from the nozzle 3. In this air blowing mode, the third switch 69 is not turned on and the heater wire 21 is not conducted, and similarly, no current is supplied to the light emitting diode 77 and no light is emitted.

  When the user pushes the slide knob 41 further up by one stage, the user is positioned at the second stage. Then, the second switch 64 shifts to the open state, and the first switch 62, the third switch 69, and the sixth switch 79 are turned on. This time, the diode 63 does not pass through the second switch 64. Is half-wave rectified and supplied to the diode bridge 65 and full-wave rectified, smoothed by the capacitor 66 and supplied to the motor 10, and the motor 10 is driven. At the same time, since the third switch 69 is in the on state, the current is supplied to the diode 70 and is half-wave rectified, and the current is supplied to the fifth switch via the thermoswitch 72 that is normally closed and in the on state. However, the current is not supplied from the time (t1-1) to the time (t1-2) when the slide knob 41 is slid in the second stage and detected by the heater control circuit 74. Is not supplied, the heater wire 21 is not heated, the fan 1 is rotated by the drive of the motor 10, and the wind passing through the inside of the wind tunnel portion 31 is not heated, and cold air is sent out from the outlet 2. However, since the sixth switch 79 is turned on, negative ions are released. At time (t1-2), the control signal for the output period is automatically output from the heater control circuit 74 instead of manually, the fifth switch 73 is turned on, and current is supplied to the heater wire 21 so that the heater is heated. The wire 21 is heated, the fan 1 is rotated by driving the motor 10, the wind passing through the inside of the wind tunnel portion 31 is also heated, and warm air is sent out from the blowout port 2. At time (t1-3), the control signal for the output stop period is automatically output from the heater control circuit 74 instead of manually, and the fifth switch is switched to be opened again, so that the heater wire 21 No current is supplied to the heater wire 21 and the heater wire 21 is not heated, and cold air is sent out from the outlet 2 and this state is continued until time (t1-4). After the time (t1-4), until the time (t1-6) when the slide knob 41 is slid to the off position, the operation from time (t1-2) to time (t1-4) is not manual but automatically. Repeatedly. In this small warm air mode, the third switch 69 is in the on state, the heater wire 21 is intermittently conducted, and current is also supplied to the light emitting diode 77 in synchronization with the intermittent conduction of the heater wire 21. It is supplied and emits light. Unlike the air blowing mode, since electric power is supplied to the motor 10 after half-wave rectification via the diode 63, the output of the motor 10 falls and the air blowing amount becomes smaller than that in the air blowing mode. Here, the time from each time to the next time can be measured by using a timer circuit, dividing the pulse transmission circuit by a frequency dividing circuit, or outputting a clock signal to the microcomputer.

  When the user pushes up the slide knob 41 further by one step, the user is positioned at the third step. Then, the first switch 62, the second switch 64, the third switch 69, the fourth switch 71, and the sixth switch 79 are turned on, and the motor 10 is supplied with power in the air blowing mode. . In addition, since the voltage is applied to the heater wire 21 not via the diode 70 but via the fourth switch 71, there is no half-wave rectification, and the power supplied to the heater wire 21 is increased and the output of the heater wire 21 is also increased. . Accordingly, the warm air is sent out from the outlet 2 as the large warm air mode at the temperature of the small warm air mode with the air volume in the air blowing mode. Further, since the sixth switch 79 is turned on, negative ions are also released. Further, similarly to the small hot air mode, a control signal is automatically output from the heater control circuit 74 instead of manually, the heater wire 21 is intermittently conducted, and intermittent hot air is sent out from the outlet 2. The In the large warm air mode, as in the small warm air mode, a current is supplied to the light emitting diode 77 in synchronization with intermittent conduction of the heater wire 21 to emit light. Here, the warm air in the small warm air mode and the warm air mode can be distinguished by light emission, and a separate light emitting diode can be provided for each, and the brightness of the light emitting diode can be changed to allow the user to identify. .

  As described above, according to the dryer according to the present embodiment, the conduction to the heater wire 21 is intermittently performed automatically instead of manually while the voltage is applied to the discharge electrode 51 and the counter electrode 55. During the heating stop period of 21 intermittent cycles, the negative ions generated by the discharge electrode 51 and the counter electrode 55 do not evaporate by receiving energy from the hot air, and the user does not perform any special operation on the hair. On the other hand, sufficient negative ions are supplied, and the hair can be dried or hair-styled so that the hair is glossy, moist and smooth. Further, after the slide knob 41 is slid to the second or third stage, the motor 10 starts to rotate and the voltage of the discharge electrode 51 starts to be applied, the heating of the heater unit 20 is not automatically performed after a predetermined time has elapsed. Therefore, only the cold air with negative ions generated by the discharge electrode 51 and the counter electrode 55 is sent out for a predetermined time after the wind starts to be sent out from the dryer, and the user's hair before the use of the dryer is started. A large amount of negative ions is supplied to the hair and firmly adhered and penetrated into the hair. After the penetration of the negative ions, warm air is sent out by the heater unit to perform hair shaping. In addition, since the time from when the motor 10 starts to rotate until it is conducted to the heater wire 21 is shorter than the heating stop period when the heater wire 21 intermittently heats, the start of the wind being sent out from the dryer Immediately after that, a large amount of negative ions can be supplied to the user's hair by using a cool air instead of a hot air. Evaporating from the surface side of the negative ions layered on the hair in turn, the negative negative ions are wasted, and it is possible to avoid the situation that the user can not do hair conditioning or drying by not switching to hot air easily, especially The user can be relatively convinced by being shorter than the intermittent heating stop period of the heater wire 21. In other words, if the user is not satisfied even with a configuration shorter than the heating stop period, the intermittent cycle of the succeeding heater wire 21 is not convinced. This is because it is also convinced that the cold air state is continued for a shorter time if it is satisfied with the intermittent period. If the user is not satisfied, the setting of the heating stop period may be wrong, and it is necessary to set the heating stop period to a level at which the consumer is satisfied, and the motor 10 is driven to rotate accordingly. What is necessary is just to adjust time until it is made to conduct to the heater wire 21 from the beginning.

  In the dryer according to the present embodiment, it is possible to provide period adjusting means such as a dial and a switch for adjusting the time of the intermittent period, and the user adjusts the time of the intermittent period according to his hair quality. Can be used. Since the degree of drying of hair differs depending on not only the hair quality but also humidity, fine adjustment is required. Here, without providing the period adjusting means, the period adjusting means can be implemented by an electronic circuit to automatically adjust the time of the intermittent period.

  In the dryer according to the present embodiment, the grip 40 can be provided with ratio adjusting means such as a dial and a switch for adjusting the ratio between the intermittent heating period and the heating stop period. The ratio of the heating period and the heating stop period can be adjusted according to the above. Since the degree of drying of hair differs depending on not only the hair quality but also humidity, fine adjustment is required. As a specific form of use, when the hair is washed and the hair is dried, the ratio of the heating period is increased and the drying of the hair is prioritized, and when the hair has been dried or when the hair is set, the ratio of the heating stop period is set. Enlarging and attaching negative ions to the hair and allowing them to permeate can be emphasized. Here, when a position for drying the hair, a position for hair styling, and a position for caring for hair are prepared as the slide position of the slide knob 41, the ratio of the heating period is increased in the position for drying the hair. It is possible to use a configuration in which the operation is performed at the intermittent cycle and the operation is performed at an intermittent cycle in which the ratio of the heating stop period is increased at other positions, and an appropriate wind can be supplied in accordance with the use situation. Specifically, in the present embodiment, the second-stage slide position is a position for hair styling (hairs are set by brazing), and the third-stage slide position is a position for drying hair. When the slide position is at the second stage, as shown in FIG. 5A, the heating period is the time from time (t1-2) to time (t1-3), and the heating stop period is time (t1- The time from 3) to time (t1-4) was set, and the heating stop period was three times the heating period, so that the hair could be sufficiently cared for with negative ions. On the other hand, as shown in FIG. 5B, when the slide is at the third stage slide position, the heating period is set to three times the heating stop period so that the hair can be sufficiently dried. Further, the heater control circuit 74 can automatically adjust the intermittent cycle time without providing the cycle adjusting means. For example, when the slide knob 41 is in a position to dry the hair, the ratio of the heating period is increased at first, and the ratio is gradually decreased with the passage of time, so that the hair is finally moistened while drying the hair. There is a hair that can be finished. In addition, when the slide knob 41 is located at a position for hair styling and hair care, the ratio of the heating stop period is initially increased, and negative ions are sufficiently adhered and penetrated, and the ratio of the gradual heating stop period is increased. By reducing the size, hair styling or care can be realized while avoiding negative ion charging.

  In the dryer according to the present embodiment, the voltage applied to the motor 10 is reduced in accordance with the intermittent heating stop period (not limited to the motor voltage control method, other field control methods, resistance control methods, and the like). (It may be a control method), the number of rotations can be reduced and the air volume from the air outlet 2 can be reduced, and the purpose is to give moisture to the hair by supplying negative ions during the heating stop period. In this case, even if a large amount of air is supplied with negative ions, the negative ions will be released in a wide direction and will not adhere to the hair sufficiently. By doing so, negative ions can be reliably supplied. In order to reduce the number of rotations of such a motor, it is desirable to gradually reduce the number of rotations of the motor by gradually lowering the applied voltage, thereby suppressing the sound and vibration associated with the change in the number of rotations of the motor. be able to.

  In the dryer according to the present embodiment, the light emitting diode 77 can emit light slightly faster than the heater wire 21 (for example, several seconds or less to 0.1 seconds or more). The user can be given a margin for directing the tip of the nozzle 3 of the dryer to the part that the user wants to dry or hair-style when viewing the emitted light.

  Further, in the dryer according to the present embodiment, the light emitting diode 77 which is a light emitting means is used as a means for notifying that warm air is being sent, but a sounding means such as a buzzer or a speaker or a vibrator or the like is used. The vibrating means can be used as an alternative to the light emitting means, or can be used in a superimposed manner. If the user is using a light-emitting means without using a mirror, even if the user is using a mirror, if the back of the hair is not reflected in the mirror using a dryer, the user can be surely notified. Although difficult, even in such a case, the user can be surely recognized by the sound generation means or the vibration means. More preferably, the user can be surely recognized by using at least two or more of light emitting means, sounding means, and vibrating means.

  In the dryer according to this embodiment, the heater control circuit 74 automatically outputs a control signal instead of manually, changes the switch state of the fifth switch 73, and determines whether or not the current is supplied to the heater wire 21. The wind that is determined and sent according to the warm or cool air is changed by the user, but the user himself / herself moves the slide knob 41 from the first stage to the second stage, from the second stage to the first stage, and the first stage. Can be adjusted from the third stage to the third stage or from the third stage to the first stage to adjust the warm and cool winds of the wind. It is also possible to make a configuration in which only the notification means is used, and the user can perform a desired operation, and the dryer notifies the user of a desired slide so that the user's request can be made. It is possible to realize an ideal operation the designer's intention is met. In addition to the simple notification by the output similar to the square wave of the control signal of the heater control circuit 74 shown in FIG. 4, when the user continues to use hot air for a long time, The flashing speed can be increased according to the length, and it can be urged strongly with time.

  In addition, the dryer according to the present embodiment may include a discharge switch (which may be a button, a slide knob, or the like in addition to the switch) that determines whether or not to operate the discharge means 50. A mode in which it is possible to determine whether or not to operate the discharge means 50, and to prevent unnecessary negative ions from being released into the hot air when the hot air and the cold air are switched, or to send only the hot air Similarly, drying can be performed with priority without releasing useless negative ions.

(Second embodiment of the present invention)
A dryer according to a second embodiment of the present invention will be described with reference to FIG. FIG. 6 is a timing chart of the dryer according to the present embodiment.
The dryer according to this embodiment has the same basic configuration as that of the dryer according to the first embodiment, and the dryer according to the first embodiment is manually operated after the rotational drive of the motor 10 and the discharge of the discharge electrode 51. In contrast, the heater unit 20 automatically heats the wind, whereas when the slide knob 41 as the operation mechanism is slid, the motor 10 is driven to rotate and the discharge electrode 51 and the counter electrode 55 are high. A voltage is applied, and the heater wire 21 is conducted and heated. The heating period at the start of heating by the heater wire 21 is longer than the heating period of the intermittent heating period by the heater unit. In addition, after the elapse of the heating period of the heating start, the heating stop period is configured to be longer than the intermittent heating period. With such a configuration, the heating starts at the beginning of drying, and then the hot air and cold air are supplied intermittently, while the specific gravity of the cold air supply period is increased to focus on the supply of negative ions to the hair. The hair can be dried at the beginning of heating, and the hair can be easily penetrated by negative ions, and the negative ions can be sufficiently permeated to achieve further hair care. For example, the heating period at the start of heating can be set to 8 [seconds], the intermittent period can be set to 8 [seconds], the heating period can be set to 2 [seconds], and the heating stop period can be set to 6 [seconds]. In the first embodiment, the intermittent period, the heating period, and the heating stop period are preferably 0.1 [seconds] to 10 [seconds]. Similarly, the heating period for starting heating is also 0.1 [seconds]. Seconds] to 10 [seconds] are desirable, and it is more desirable to be several tens of seconds to several minutes.

In the air blowing mode in which the slide knob 41 is slid to the first stage, since there is no conduction to the heater wire 21, the operation is the same as that of the dryer according to the first embodiment.
In the small warm air mode in which the slide knob 41 is slid to the second stage, the second switch 64 shifts to the open state, and the first switch 62, the third switch 69, and the sixth switch 79 are turned on. In this state, full-wave rectification is performed by the diode bridge 65, smoothed by the capacitor 66, supplied to the motor 10 and driven, and half-wave rectified by the diode 70, current flows into the fifth switch, and the slide knob 41 is Between the time (t2-1) and the time (t2-2) when the heater control circuit detects that the second stage has been slid, the current is already supplied to the heater wire 21 and the heater wire is supplied. 21 is heated, the fan 1 is rotated by driving the motor 10, and the wind passing through the inside of the wind tunnel 31 is also heated, and warm air is sent out from the air outlet 2. Here, since the sixth switch 79 is turned on, negative ions are also released. At time (t2-2), a control signal for the output stop period is automatically output from the heater control circuit 74 instead of manually, the fifth switch 73 is opened, and current is supplied to the heater wire 21. Without the heater wire 21 being heated, the fan 1 is rotated by the drive of the motor 10, and the wind passing through the inside of the wind tunnel portion 31 is not heated, and cold air is sent out from the blowout port 2. When the time (t2-3) is reached, the control signal for the output period is automatically output from the heater control circuit 74 instead of manually, and the fifth switch is switched to be turned on again. Electric current is supplied to heat the heater wire 21, and warm air is sent out from the blowout port 2, and this state is continued until time (t2-4). After the time (t2-4), until the time (t2-6) when the slide knob 41 is slid to the off position, the operation from time (t2-2) to time (t2-4) is not manual but automatically. Repeatedly. In this small warm air mode, the third switch 69 is in the on state, the heater wire 21 is intermittently conducted, and current is also supplied to the light emitting diode 77 in synchronization with the intermittent conduction of the heater wire 21. It is supplied and emits light. As shown in FIG. 6, the heating stop period from time (t2-2) to time (t2-3) is three times the heating period from time (t2-3) to time (t2-4), and the intermittent period The ratio of the middle heating stop period is increased, and hair care is realized by focusing on the supply of negative ions to the hair during the intermittent period.

  In the hot air mode in which the slide knob 41 is slid to the third stage, the first switch 62, the second switch 64, the third switch 69, the fourth switch 71, and the sixth switch 79 are turned on. In this state, the motor 10 is supplied with power in the air blowing mode. Further, since the voltage is applied to the heater wire 21 not via the diode 70 but via the fourth switch 71, there is no half-wave rectification and the fifth switch 73 flows in, and the time (t2 -1) immediately after the slide knob 41 slides, the fifth switch 73 is turned on, the power supplied to the heater wire 21 is increased, and the output of the heater wire 21 is also increased. By doing so, the warm air is sent out from the outlet 2 as the large warm air mode at the temperature of the small warm air mode with the air flow rate in the air blowing mode immediately after the slide. Further, since the sixth switch 79 is turned on, negative ions are also released. The user's hair dries during the time from time (t2-1) to time (t2-2), and the time from time (t2-2) to time (t2-3) is the control signal from the heater control circuit 74. As a result, the fifth switch 73 is opened and negative ions that are not heated and do not have the energy to evaporate are released and adhere to and penetrate into the user's hair. During the period from time (t2-3) to time (t2-4), the fifth switch 73 is turned on again to dry and blow the user's hair, or the hair is on the surface of the user's hair. Evaporate excess negative ions that have not penetrated. After the time (t2-4), the operation from the time (t2-2) to the time (t2-4) is automatically repeated instead of manually, and the slide knob 41 is slid to the off position (t2-6) ) Is done. As in the small hot air mode, a control signal is automatically output from the heater control circuit 74 instead of manually, the heater wire 21 is intermittently conducted, and intermittent hot air is sent out from the air outlet 2. In the large warm air mode, as in the small warm air mode, a current is supplied to the light emitting diode 77 in synchronization with intermittent conduction of the heater wire 21 to emit light.

  As described above, according to the dryer according to the present embodiment, the operation of the slide knob 41 starts driving the motor 10, applying voltage to the discharge electrode 51 and the counter electrode 55, and heating the heater wire 21. Since the heating period immediately after the start of heating (not the intermittent heating period) is longer than the heating period when the heater wire 21 is intermittently heated, the motor 10 is driven to rotate, to the discharge electrode 51 and the counter electrode 55. The normal warm air is sent out by applying the voltage and starting the heating of the heater wire 21. First, the hair of the user is dried by the warm air, and the negative ions are easily attached to the cold air without the energy to evaporate. The negative ions can be attached to the dry hair, making it easier for the negative ions to penetrate smoothly, making the hair shiny, moist and smooth.

  Although the heating period immediately after the heating of the heater wire 21 is started by operating the slide knob 41, an initial heating period adjusting means such as a switch or a dial for adjusting the heating period immediately after the start of heating can be provided. When hair is dried and blown, the initial time required for warm air varies depending on the user and varies depending on the temperature and humidity of the space in which the dryer is used. The warm air can be obtained only for a desired time by adjusting accordingly. Here, the initial heating period adjusting means can be realized by setting different initial heating periods for each of a plurality of slide positions.

(Third embodiment of the present invention)
A dryer according to a third embodiment of the present invention will be described with reference to FIG. 7 or FIG. FIG. 7 is a circuit diagram of the dryer according to the present embodiment, and FIG. 8 is a timing chart of the dryer according to the present embodiment.
The dryer according to the present embodiment is configured in the same manner as the dryer according to the second embodiment, and not only automatically and intermittently conducts the heater wire 21 but also the discharge electrode 51 and the counter electrode. In this configuration, voltage application to 55 is intermittently performed automatically instead of manually.

  As shown in the circuit diagram of FIG. 7, a seventh switch 81 is disposed between the rectifier circuit 80 and the pulse generation circuit 53 which are circuit portions related to discharge, and a control signal is output only to the fifth switch 73. In place of the heater control circuit 74, the heater / discharge control circuit 82 includes the function of the heater control circuit 74 and outputs a control signal to the seventh switch 81. A step-down circuit 83 to be supplied to the circuit 82 is disposed.

  The heater / discharge control circuit 82 does not separately output a control signal to each of the fifth switch 73 and the seventh switch 81, but the seventh switch 73 is turned on when the fifth switch 73 is turned on. When the switch 81 is opened and the fifth switch 73 is opened, the control signal is automatically sent to the fifth switch 73 and the seventh switch 81 instead of manually so that the seventh switch 81 is turned on. Output. Each of these control signals is generated by forming a transmission circuit, appropriately dividing the transmission signal from the transmission circuit, outputting a desired pulse as a control signal to the fifth switch 73, This can be realized by outputting an inverted signal to the seventh switch 81. Thus, since the control signal output to the fifth switch 73 and the control signal output to the seventh switch 81 have a mutual relationship, the heater control circuit 74 and a new discharge control circuit are separately provided. Without being provided, a circuit was mounted as the heater / discharge control circuit 82. In the case of such circuit mounting, as exemplified in the first embodiment and the second embodiment, for example, one period of the intermittent period is set to 8 [seconds], the heating period is set to 4 [seconds], It is possible to set the heating stop period to 4 [seconds], the heating start heating period to 8 [seconds], the discharge period to 4 [seconds], and the discharge stop period to 4 [seconds]. In the first embodiment and the second embodiment, the intermittent period, the heating period, the heating stop period, and the heating period of the heating start are preferably 0.1 [seconds] to 10 [seconds]. In addition, the discharge period and the discharge stop period are preferably 0.1 [second] to 10 [second], and more preferably about several tens of seconds to several minutes. Here, the heater control circuit 74 and the discharge control circuit can be provided separately, but a synchronization signal is output from at least one to the other, or the heater control circuit 74 and the discharge control circuit are controlled. Circuit is required, and the configuration is substantially the same as that of the heater / discharge control circuit 82.

  A resistor 84 and a light emitting diode 85 are connected in parallel to the transformer 52 for applying a high voltage to the discharge electrode 51 and the counter electrode 55, and the seventh switch is turned on to apply a voltage to the transformer, A current also flows into the light emitting diode 85, and the light emitting diode 85 emits light.

Next, the operation of the dryer according to this embodiment will be described.
In the air blowing mode, the third switch 69 is not turned on, and the heater / discharge control circuit 82 does not automatically output a control signal to the fifth switch 73 instead of manually. The sixth switch 79 is turned on, current flows into the seventh switch 81, and the heater / discharge control circuit 82 is turned off when the slide knob 41 is slid and positioned at the first stage regardless of the elapsed time. Until it is slid to the position, the control signal for the output period is automatically output to the seventh switch 81 instead of manually. Therefore, in the blow mode, voltage is applied to the discharge electrode 51 and the counter electrode 55 and discharges negative ions on the wind until the cold air starts to be sent from the outlet 2 and ends. While the negative ions are being emitted, the light emitting diode 85 emits light as described above. Here, in the case of cold air, it does not evaporate by giving energy to negative ions as compared with hot air, but the negative ions are supplied too much to the hair and the hair is negatively charged, and the subsequent air is sent out. Since fresh negative ions have the same polarity, they cannot repel from the hair and adhere to and penetrate into the hair. Therefore, even when the heater / discharge control circuit 82 is in the air blowing mode, the control signal for the output period and the output stop period is intermittently output automatically to the seventh switch 81 instead of manually, so that the discharge electrode 51 and the counter electrode 55 It is also possible to prevent the negative ions associated with the wind that is sent out by intermittently applying the voltage, and to prevent charging by excessive negative ions.

  When the slide knob 41 is slid to the second stage and enters the small warm air mode, the third switch 69 is turned on, and the time when the heater / discharge control circuit 82 detects that the slide knob 41 has been slid At (t3-1), the heater / discharge control circuit 82 automatically outputs a control signal for the output period to the fifth switch 73, and the heater wire 21 is heated automatically, but not manually, but automatically. A control signal for the output stop period is output from the discharge control circuit 82 to the seventh switch 81, and no voltage is applied to the discharge electrode 51 and the counter electrode 55. At the time (t3-2) when a predetermined time elapses from the time (t3-1), the heater / discharge control circuit 82 automatically outputs the control signal for the output stop period to the fifth switch 73 instead of manually. While the heater wire 21 is not heated, a control signal for the output period is output from the heater / discharge control circuit 82 to the seventh switch 81 automatically instead of manually, and a voltage is applied to the discharge electrode 51 and the counter electrode 55 to apply negative ions. And discharged from the outlet 2. At time (t3-3), a control signal is automatically output from the heater / discharge control circuit 82 to the fifth switch 73 and the seventh switch 81 instead of manually as at time (t3-1). After time (t3-4), voltage is applied to the heater wire 21, the discharge electrode 51, and the counter electrode 55 based on the control signal from the heater / discharge control circuit 82 from time (t3-2) to time (t3-4). Is applied. From time (t3-1) to time (t3-2), from time (t3-3) to time (t3-4), from time (t3-4) to time (t3-3) to time During a period corresponding to (t3-4), since the current is also supplied to the heater wire 21, the light emitting diode 77 emits light. The transformer 52 is used between the time (t3-2) and the time (t3-3), and between the time (t3-4) and the time (t3-3) after the time (t3-4). Since the voltage is also applied to the light emitting diode 85, the light emitting diode 85 emits light. Therefore, the light emitting diode 77 and the light emitting diode 85 alternately emit light based on the control signal of the heater / discharge control circuit 82. In the case of the large warm air mode, the operation is performed in accordance with the small warm air mode. As a different operation, the second switch 64 and the fourth switch 71 are turned on, and the motor 10 and the heater wire 21 are higher. It is a point that operates as an output.

  As described above, according to the dryer according to the present embodiment, not only the heating of the heater wire 21 is automatically performed intermittently, but also the voltage application to the discharge electrode 51 and the counter electrode 55 is not manual but automatic. Since there is an intermittent heating period of the heating of the heater wire 21, a large amount of negative ions generated by the discharge are supplied to the user's hair and charged negatively, This prevents negative ions from repelling due to this charge and preventing the supply of fresh, non-evaporating energy negative ions to the hair, and efficiently supplying negative ions without charging by supplying the appropriate amount of negative ions. Can penetrate into the hair. Further, the intermittent heating by the heater wire 21 has a heating period and a heating stop period. By preventing the negative ions from being supplied without discharging during the heating period, the water molecules are prevented from being charged by the excessive negative ions. For the hair in a state where a large amount of negative ions are easily attached by the warm air by discharging energy during the heating stop period by evaporating by supplying energy with warm air and evaporating it. Since it supplies, an unnecessary negative ion is not produced | generated and efficient operation | movement can be performed. Further, since the light emitting diode 85 is provided to emit light during the voltage application period of the discharge electrode 51 and the counter electrode 55, the user not only visually confirms the heating period by light emission of the light emitting diode 77 but also the discharge period. Can be visually confirmed by the light emission of the light-emitting diode 85, and even during the discharge period, since a person cannot feel it even if it receives the release of negative ions, the negative ions are released visually. It becomes possible to use it efficiently after knowing.

  In the dryer according to the present embodiment, it is possible to provide a rate adjusting means such as a dial or a switch for adjusting the rate of the intermittent heating period and the heating stop period, and the user can adjust the hair quality to his own. The ratio between the heating period and the heating stop period can be adjusted and used. The difference from the first embodiment is that, in this embodiment, the negative ions are released only when the cold air is delivered because discharge is performed in accordance with the intermittent heating stop period, and excessively adheres to the hair when the hot air is delivered. In such a case, the negative ion release period changes depending on the adjustment by the ratio adjusting means, and this significantly changes the amount of negative ion release, so that the user can adjust Especially important.

  Further, in the dryer according to the present embodiment, the voltage applied to the motor 10 is reduced in accordance with the intermittent heating stop period in the first embodiment, the rotational speed is reduced, and the air volume from the outlet 2 is reduced. In addition to the configuration of performing this, it is also possible to increase the voltage applied to the motor 10 in accordance with the intermittent heating period and increase the rotational speed to increase the air volume from the outlet 2, and this embodiment In the heating period, since no discharge occurs, negative ions are not released, and only the negative ions that do not penetrate into the hair are evaporated by the warm air, and the rotation speed of the motor 10 is increased during the heating period. Raising the evaporation of unnecessary negative ions can be promoted. More reliably, it is desirable to increase the output to the heater wire 21 at the same time.

  Further, in the dryer according to the present embodiment, in addition to the configuration in which the light emission of the light emitting diode 77 in the first embodiment emits light slightly (for example, several seconds to 0.1 seconds or more) faster than the heating of the heater wire 21. Thus, the light emission of the light emitting diode 85 is configured to emit light slightly earlier than the discharge (for example, several seconds or less to 0.1 second or more). The user can be given a margin for directing the tip of the nozzle 3 and a margin for directing the tip of the nozzle 3 of the dryer to a portion where the user wants to supply negative ions when the light emitted from the light emitting diode 85 is viewed.

  Further, in the dryer according to the present embodiment, the light emitting diode 85 which is a light emitting means is used as a means for notifying that negative ions are being sent, but a sounding means such as a buzzer or a speaker, a vibrator or the like is used. The vibrating means can be used as an alternative to the light emitting means, or can be used in a superimposed manner.

  In addition, the dryer according to the present embodiment may include a discharge switch (which may be a button, a slide knob, or the like in addition to the switch) that determines whether or not to operate the discharge means 50. Whether or not the discharge means 50 can be operated can be determined. Even when the discharge means 50 is intermittently discharged and intermittently releases negative ions, there are cases where it is desired to receive cold air without receiving negative ions. In a humid and hot environment, there are cases where it is desired to dry only with cold air while receiving a refreshing feeling rather than moisturizing hair and scalp. Further, such a discharge switch can be used as a switch for continuously discharging rather than intermittently discharging. Depending on the amount of hair and the length of the hair, even if negative ions are continuously released, the negative ions may not be stacked excessively, so users with large amounts of hair, users with long hair, while floating hair In the case of a user who can uniformly supply negative ions to the entire hair, it is sometimes desirable to supply negative ions continuously instead of intermittently because negative ions are not excessively stacked.

  In order to emit light toward the suction port 4, as shown in FIGS. 9A and 9B, a partition plate 90 is formed on the upper portion of the case body 30 of the wind tunnel portion 31, and the suction port 4 of the partition plate 90 is formed. A light emitting diode 77 and a light emitting diode 85 are arranged in parallel on the side. The color of the light-emitting diode can be recalled that the light-emitting diode 77 is red and the light-emitting diode 85 is blue. If the user sees, the light-emitting diode 77 is related to the heater and the light-emitting diode 85 is related to negative ions. I have to. If the light-emitting diode 77 and the light-emitting diode 85 are simply arranged on the upper part of the case body 30 of the wind tunnel portion 31, the light from the light-emitting diode that is not condensed unlike the laser is emitted in all directions, and a dryer is used. It is necessary to use a light-emitting diode (double heterojunction structure, quantum well junction structure) having a high brightness so that the user can visually recognize the illuminance. However, by forming the partition plate 90 shown in FIG. 9 and specifying the radiation direction, it is possible to make the user visually aware even if the light emitting diode is not a connection structure with high luminance. In other words, this can be dealt with by limiting the light emission direction. Here, the limitation to the suction port 4 is that when the user uses the dryer using a mirror, the back side of the dryer is often shown as shown in FIG. Because.

  As described above, according to the dryer according to the present embodiment, the light emitting diode 77 and the light emitting diode 85 emit light toward the suction port 4, so that the user faces the mirror 91 of the washstand when using the dryer. In such use, in many cases, the suction port 4 side is in a state of being reflected on the mirror 91. By providing the light-emitting diode 77 and the light-emitting diode 85 at the suction port 4, the user can surely see Can be convenient.

  In the dryer according to this embodiment, only the partition plate 90 or the light emitting diode 77 and the light emitting diode 85 portion can be covered with a hemispherical reflecting plate that opens toward the suction port 4 side.
