Description

The present invention relates to a heating blower.

Conventionally, as a heating blower, a device including a blower unit for discharging air sucked from a suction port from an air outlet and a heating part for heating the air blown by the blower unit is known (for example, Patent Document). 1).

In Patent Document 1, the hot air mode and the cold air mode are automatically switched alternately by intermittently energizing the heating unit. That is, hot air and cold air are alternately discharged from the discharge port of the heating blower device at a predetermined cycle.

Then, hot air and cold air are alternately discharged from the discharge port, and hot air and cold air are alternately applied to the hair so that the hair can be stretched and the hair can be glossed. There is.

Specifically, when warm air is applied to the hair, heat is applied to the hair and the hydrogen bonds between the hair fibers are broken. Therefore, when warm air is blown to the hair (when the hydrogen bonds between the hair fibers are broken), it is easier to shape the hair by using a hand or a brush to prepare the hair. It can be (a shape with an extended habit, etc.). On the other hand, when cold air is applied to the hair in which the hydrogen bonds between the hair fibers are broken, the hair is cooled and the hair fibers are in a hydrogen bonded state. Therefore, if the hair shaped into a desired shape is cooled by applying cold air, the hair fibers are hydrogen-bonded to each other in the state of being shaped into a desired shape, and the hair can be maintained in a desired shape.

In this way, if the hot air and the cold air are alternately discharged from the discharge port, the hair can be set in a desired shape, and the hair treatment effect can be enhanced.

However, when trying to prepare the hair tips with a brush or the like, it is difficult to keep applying tension to the hair tips, and a sufficient treatment effect may not be obtained.

Further, in the above-mentioned conventional technique, the energization time to the heating unit is 3 to 10 seconds, and the switching cycle between hot air and cold air is relatively long, 12 seconds. Therefore, if you try to keep applying tension to the hair tips with your hands, warm air will hit your hands for a long time, and it will be difficult to keep applying tension to the hair tips with your hands, and you will still get a sufficient treatment effect. It may not be possible.

As described above, in the above-mentioned conventional technique, it is difficult to prepare the tips of the hair by using a hand or a brush due to the heat and the treatment operation, and the hair may not be sufficiently treated.

An object of the present invention is to solve the above-mentioned conventional problems, and to provide a heating blower capable of further enhancing the hair treatment effect.

It is provided with an air volume control unit having a first air flow control mode for controlling the air volume and a second air flow control mode for controlling the air volume to be larger than 1 m ³ / min .

Further, the period in which the hot air and the cold air are alternately discharged in the state where the first air blowing control mode and the hot / cold mode are selected is the state in which the second air blowing control mode and the hot / cold mode are selected. It is shorter than the cycle in which hot air and cold air are alternately discharged, and the energization control unit has the energization time of the first air blow control mode in the state where the hot / cold mode is selected. It is controlled so that it is equal to or less than the energizing time of the ventilation control mode .

Then, in the state where the heating / cooling mode is selected by the ventilation mode selection unit, the energization control unit sets the energization time for energizing the heating unit within the predetermined cycle to 3 seconds or less, and the heating unit. product of power and the energizing time of inputting are to have a first energization control mode for controlling so as to 1000W · s or more, when the first air blowing control mode is operating, the The first energization control mode is operated .

In this way, the hair temperature (hair temperature at which hydrogen bonds between hair fibers can be broken) required for treatments such as straightening the habit of hair can be obtained in a relatively short time, and it becomes easier to arrange the hair tips. Therefore, it is possible to further improve the hair treatment effect.

According to the present invention, it is possible to obtain a heating blower capable of further enhancing the hair treatment effect.

Then, the first energization control mode may be operated while the first ventilation control mode is operating.

By doing this, the hair tips are prevented from escaping (too much loosening) due to the wind, so that heat can be transferred to the hair tips more stably, and the hair treatment The effect can be further improved.

Further, the heating blower is provided in the housing to generate charged particles, and a charged particle generation amount control unit that controls the generation amount of charged particles generated by the charged particle generation unit. , May be further provided.

Then, the charged particle generation amount control unit controls the first charged particle generation amount control mode and the second charged particle generation amount control that generates charged particles in an amount different from the first charged particle generation amount control mode.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to this embodiment.

(Embodiment 1)
The hair dryer 1 as a heating blower according to the first embodiment includes a grip portion 1a as a portion to be gripped by a user and a main body portion 1b connected in a direction intersecting the grip portion 1a. At the time of use, the grip portion 1a and the main body portion 1b are configured to be foldable so as to have a substantially T-shaped or substantially L-shaped appearance (approximately T-shaped in the first embodiment).

The power cord 2 is pulled out from the protruding end of the grip portion 1a. Further, the grip portion 1a is divided into a root portion 1c and a tip portion 1d on the main body portion 1b side, and the root portion 1c and the tip portion 1d are rotatably connected via the connecting portion 1e. There is. The tip portion 1d can be folded to a position along the main body portion 1b.

The housing 3 that forms the outer wall of the hair dryer 1 (constituting the outer shell) is formed by joining a plurality of divided bodies. A cavity is formed inside the housing 3, and various electric components are housed in the cavity.

Inside the main body 1b, there is a wind tunnel (air flow path) 4 from the inlet opening (suction port) 4a on one side (right side) in the longitudinal direction (left-right direction in FIG. 3) to the outlet opening (discharge port) 4b. It is formed, and a blower portion 5 is housed in the wind tunnel 4. The blower portion 5 includes a fan 5a and a motor 5b that rotates the fan 5a. Then, the air flow W is formed by driving the motor 5b to rotate the fan 5a. This air flow W flows into the wind tunnel 4 from the outside through the inlet opening 4a, mainly passes through the wind tunnel 4, and is discharged to the outside from the outlet opening 4b.

In the first embodiment, the inlet opening (suction port) 4a is covered with a mesh-like frame 81, and the shape of the opening of the frame 81 is a honeycomb shape. Further, as shown in FIG. 3, the frame body 81 is integrally formed with a mesh 82 having an aperture ratio of about 55 to 90% and a mesh width of about 300 to 650 μm. A flame-retardant resin such as metal or polyester can be used for the mesh 82. By integrally molding the mesh 82 having a fine mesh width in this way, fine dust, hair, etc. can enter the air flow path. It makes it possible to suppress it more reliably.

Further, in the main body 1b, a substantially cylindrical inner cylinder 6 is provided inside the outer cylinder 3a of the housing 3, and the air flow W mainly flows inside the inner cylinder 6. .. Inside the inner cylinder 6, the fan 5a is arranged on the most upstream side, the motor 5b for driving the fan 5a is arranged on the downstream side thereof, and the heater 8 as a heating unit is arranged on the further downstream side of the motor 5b. There is.

Then, when the heater 8 is operated, warm air is blown out from the outlet opening 4b. In the first embodiment, the heater 8 is configured as a band-shaped and corrugated plate-shaped electric resistor wound around the inner circumference of the inner cylinder 6 and arranged, but the configuration is limited to this. Not done.

The inner cylinder 6 is supported by a tubular portion 6a, a plurality of support ribs 6b extending outward in the radial direction from the tubular portion 6a and dispersed in the circumferential direction (only one location is shown in FIG. 3). It has a flange portion 6c that is connected to the tubular portion 6a via a rib 6b and projects in a direction substantially orthogonal to the axial direction of the tubular portion 6a.

A gap g1 is formed between the tubular portion 6a and the flange portion 6c, and a part of the air flow W is branched and flows into the cavity 9 through the gap g1 (a branched flow is formed). Is done). The gap g1 serving as an introduction port for the branch flow cavity 9 is provided at a position downstream of the fan 5 and upstream of the heater 8. Therefore, the branch flow is a relatively cold air flow before being heated by the heater 8.

Further, a part of the branched flow that has flowed into the cavity 9 is further branched, passes between the inner cylinder 6 and the housing 3, and is blown out from the outer peripheral portion of the outlet opening 4b. A part of this branch flow passes between the inner cylinder 6 and the housing 3 without passing through the metal fine particle outlets (charged particle outlets) 20a and 20b and the mist outlets (charged particle outlets) 20c, which will be described later. It is a relatively cold air flow that is blown out from the outer peripheral portion of the outlet opening 4b.

In the first embodiment, a substantially arc-shaped through hole (opening) 3b is formed at a position on the exit opening 4b side of the cavity 9 in the housing 3, and the through hole 3b is made of an insulating synthetic resin material. It is covered with a cover 20. The cover 20 is attached to the housing 3 by moving the cover 20 from the downstream side to the upstream side with respect to the housing 3.

Further, a substantially cylindrical outer nozzle 20f is integrally formed on the downstream side of the cover 20, and when the cover 20 is attached to the housing 3, the outer circumference of the outlet opening 4b is defined by the outer nozzle 20f. I am trying to do it.

Further, an inner nozzle 21 having a substantially cylindrical shape having a diameter smaller than that of the outer nozzle 20f is attached to the downstream end of the inner cylinder 6, so that the downstream opening of the inner nozzle 21 becomes a part of the outlet opening 4b. I have to.

As described above, in the first embodiment, the inner nozzle 21 is attached to the downstream end of the inner cylinder 6 and the cover 20 is attached to the housing 3, so that the outer nozzle 20f and the inner nozzle 21 have a double cylinder structure. The nozzle is formed.

Therefore, most of the air flow W formed by driving the blower portion 5 becomes the main air flow W1 that is introduced into the inner cylinder 6 and blown out from the opening of the inner nozzle 21 (the center of the outlet opening 4b). However, a part of the air flow W becomes a branch flow W2 or a branch flow W3. The branch flow W2 flows into the cavity 9 and does not pass through the metal fine particle outlets 20a and 20b and the mist outlet 20c, but is between the outer nozzle 20f and the inner nozzle 21 (outer peripheral side of the outlet opening 4b). It is an air flow blown out from. Further, the branch flow W3 is an air flow that flows into the cavity 9 and is blown out from the metal fine particle outlets 20a and 20b and the mist outlet 20c.

Further, in the first embodiment, the main air flow W1 is blown out from two window portions (first window portion 231 and second window portion 232) formed in the inner nozzle 21. (See FIGS. 5 and 7).

Specifically, the inner nozzle 21 includes a substantially cylindrical main body 210 and a crosspiece 220 that divides the internal space of the main body 210 into two spaces. The crosspiece 220 is formed so as to extend in the vertical direction to the central portion in the horizontal direction of the main body 210. By doing so, the windows 231,232 are formed on the left and right sides of the inner nozzle 21, respectively.

A plurality of mounting piece portions 211 are formed on the outer periphery of the main body portion 210, and by engaging the mounting piece portions 211 with the inner cylinder 6, the inner nozzle 21 can be attached to the inner cylinder 6. There is.

Further, as shown in FIG. 7, the crosspiece 220 is formed so that the shape of the horizontal cross section is substantially U-shaped. That is, a pair of left and right wall portions 221,221 formed on the downstream side of the crosspiece 220 extend substantially parallel to the front-rear direction (blower direction).

If the inner nozzle 21 having such a configuration is used and the air flow is discharged from the two window portions 231,232, the wind (warm air or cold air) can be applied to the hair more evenly. .. Then, if the wind is applied to the hair more evenly, the hair can be loosened (split) appropriately, so that the drying performance of the hair can be further improved.

However, if the inner nozzle 21 shown in FIG. 5 is used to discharge air from the outlet opening 4b, a negative pressure is generated in the vicinity of the downstream side of the crosspiece 220. Therefore, even if the main air flow W1 blown out from the inner nozzle 21 is branched into two air streams (two bundles of air), the two air streams merge at a relatively early stage (see FIG. 7). ). Therefore, when the inner nozzle 21 shown in FIG. 5 is used, there is a high possibility that almost one bundle of air flow hits the hair, and the drying performance of the hair may not be improved.

Therefore, it is preferable to use the inner nozzle 21A shown in FIGS. 6 and 8 instead of the inner nozzle 21.

The inner nozzle 21A also includes a substantially cylindrical main body 210A and a crosspiece 220A that divides the internal space of the main body 210A into two spaces, and the crosspiece 220A is centered in the left-right direction of the main body 210A. It is formed so as to extend in the vertical direction in the portion. In this way, the windows 231A and 232A are formed on the left and right sides of the inner nozzle 21A, respectively.

Further, a plurality of mounting piece portions 211A are formed on the outer periphery of the main body portion 210A, and by engaging the mounting piece portion 211A with the inner cylinder 6, the inner nozzle 21A can be attached to the inner cylinder 6. ing.

Here, in the inner nozzle 21A, as shown in FIG. 8, the crosspiece 220A is formed so that the horizontal cross-sectional shape is substantially V-shaped. That is, the pair of left and right wall portions 221A and 221A formed on the downstream side of the crosspiece 220A are provided so as to be separated from each other toward the downstream side. By doing so, the main air flow W1 blown out from the inner nozzle 21 is more reliably branched into two air flows (two bundles of air).

Further, in the inner nozzle 21A, groove portions 212A and 212A recessed toward the center are formed at both upper and lower ends of the main body portion 210A, respectively, and the groove portions 212A and 212A have a groove depth on the downstream side and a groove on the upstream side. It is formed to be deeper than the depth.

When such groove portions 212A and 212A are provided in the main body portion 210A, when air is discharged from the outlet opening 4b, the air is blown out from between the outer nozzle 20f and the inner nozzle 21 (outer peripheral side of the outlet opening 4b). The branch flow W2 to be generated flows to the central portion on the downstream side of the crosspiece 220A. Therefore, the negative pressure generated in the vicinity of the downstream side of the crosspiece 220A can be relaxed.

In this way, if the inner nozzle 21A is used instead of the inner nozzle 21, negative pressure is suppressed in the vicinity of the downstream side of the crosspiece 220A, so that two air flows (two bundles of air) are formed. The branched state can be maintained more reliably. As a result, two air streams (two bundles of air) can be applied to the hair, and the hair can be loosened (split) appropriately, so that the drying performance of the hair can be further improved. Become.

Further, in the cavity 9 formed between the housing 3 and the inner cylinder 6 in the main body 1b, two (plurality) metal fine particle generation parts (ion generation part: charged particle generation part) 30, 40 and the like , A mist generation unit (ion generation unit: charged particle generation unit) 50, a voltage application circuit 12 for applying a voltage to the mist generation unit 50, and the like are housed. Further, a voltage application circuit 13 that applies a voltage to the metal fine particle generating units 30 and 40 is housed in a portion different from the portion of the cavity 9 in which the voltage application circuit 12 is housed.

It is preferable that the voltage application circuit 12 and the voltage application circuit 13 are arranged in the grip portion 1a or in the main body portion 1b in a region that is an extension line of the grip portion 1a. This is to reduce the rotational moment caused by the mass of the voltage application circuit 12 and the voltage application circuit 13 when the user holds the grip portion 1a, and reduce the load acting on the user's hand.

Further, it is preferable that the voltage application circuit 12 and the voltage application circuit 13 are arranged at positions opposite to each other with the inner cylinder 6 interposed therebetween. By doing so, it is possible to suppress problems such as voltage drop and instability due to mutual interference between the voltage application circuit 12 and the voltage application circuit 13.

Further, in the first embodiment, switching (selection) between hot air and cold air and selection of an operation mode are performed on the side surface portion of the main body portion 1b (a portion different from the portion in which the voltage application circuit 12 of the cavity 9 is housed). A switch unit (blower mode selection unit) 19 for performing the above is provided.

Further, the tip portion 1d of the grip portion 1a is provided with another switch portion (blower mode selection portion) 16 for switching the power on / off. These electric components are connected to each other by a lead wire 17 in which a core wire made of a metal conductor or the like is coated with an insulating resin or the like.

The lead wire 17 connected to the metal fine particle generation unit 30, the lead wire 17 connected to the metal fine particle generation unit 40, and the lead wire 17 connected to the mist generation unit 50 should be arranged as far apart as possible without crossing each other. Suitable. This is to prevent the metal fine particle generating units 30 and 40 or the mist generating unit 50 from being unable to obtain a desired voltage or becoming unstable due to mutual interference of the currents flowing through the respective lead wires 17. ..

In the first embodiment, the switch unit 16 is configured so that the open / closed state of the internal contact can be switched by operating the operator 16a exposed on the surface of the housing 3. At this time, by sliding the operator 16a in the vertical direction, it is possible to switch the open / closed state of the internal contact in multiple stages.

For example, it is possible to switch between four modes: power off, light wind, medium wind, and strong wind. In this case, the power can be turned off when the operator 16a is positioned at the lowermost position.

Then, when the operator 16a is slid one step upward from the lowermost position, the power is turned on and a weak wind can be blown. Further, when the operator 16a is slid upward by one step, a medium wind is blown, and when the operator 16a is slid to the uppermost part, a strong wind can be blown.

On the other hand, the switch unit 19 that switches between hot air and cold air, operates a mode, and the like switches the open / closed state of the internal contact by operating (pressing) the operator 19a formed on the surface (side surface) of the housing 3. Is configured to allow A display unit 14 for displaying the currently selected mode is formed above the operator 19.

The switch unit 19, the display unit 14, and the like are electrically connected to the control unit 10.

In the first embodiment, the four air temperature modes of "HOT", "hot / cold", "COLD", and "SCALP" can be switched by operating the operator 19. At this time, characters or the like capable of recognizing the selected mode are displayed on the display unit 14.

Hereinafter, an example of each mode and the display method on the display unit 14 will be described.

The "HOT" is a mode in which warm air is output, and the temperature of the wind that hits the hair during normal use is set to about 70 ° C to 80 ° C. When the mode for outputting the warm air is selected, the characters "HOT" can be displayed on the display unit 14.

Further, "hot / cold" is a mode in which hot air and cold air are alternately output, such as (hot air 5 seconds, cold air 7 seconds) and (warm air 2 seconds, cold air 6 seconds). When this "hot / cold" mode is selected, an arrow is displayed on the display unit 14, and "HOT" and "COLD" are displayed alternately according to the output of hot air and cold air. Can be done.

Further, "COLD" is a mode in which cold air is output, and the temperature of the wind that hits the hair during normal use is set to about 30 ° C. When the mode for outputting the cold air is selected, the characters "COLD" can be displayed on the display unit 14.

Further, "SCALP" is a mode in which low-temperature wind is output, and the temperature of the wind that hits the hair during normal use is set to about 50 ° C. This "SCALP" mode is set as a mode mainly selected when caring for the scalp. Then, when the "SCALP" mode is selected, the characters "SCALP" can be displayed on the display unit 14.

Then, when the operator 16a is slid upward to turn on the power, the control unit 10 is energized, the heater 8 is driven by the drive signal corresponding to the current ventilation mode, and the current ventilation mode is displayed. The display of the display unit 14 is controlled. In the state where the operator 16a is slid upward and the power is simply turned on, the "HOT" mode is selected and warm air is blown.

Then, each time the operator 19a is operated, a pressing signal is sent to the control unit 10, and the four air temperature states are switched in the order of "warm / cold" mode, "COLD" mode, "SCALP" mode, and "HOT" mode. It has become like.

Further, in the first embodiment, the characters "SKIN" are formed on the display unit 14, and when "COLD" is selected in the weak wind mode, "SKIN" is displayed together with "COLD". I have to.

That is, when "COLD" is selected in the weak wind mode, it can also be used as the "SKIN" mode. The "SKIN" mode is a mode selected for skin care, such as applying cold air containing mist or the like to the skin to keep the skin moisturized in an appropriate state.

The above description is merely an example, and various methods can be used as the display method for each mode. In addition, various modes can be set for the switching mode between hot air and cold air.

Further, as described above, the cover 20 is formed with the metal fine particle outlets (ion outlets) 20a and 20b and the mist outlets (ion outlets) 20c independently.

An ion flow path 4c through which ions flow is formed in front of the mist generation unit (ion generation unit: charged particle generation unit) 50 and the metal fine particle generation unit (ion generation unit: charged particle generation unit) 30 and 40. Therefore, the metal fine particle outlets (ion outlets) 20a and 20b and the mist outlets (ion outlets) 20c are provided on the downstream side of the ion flow path 4c.

Further, the cover 20 is preferably made lower in conductivity than the housing 3 in order to suppress charging due to metal fine particles or mist. This is because when the cover 20 is charged, the charged metal fine particles and negative ions and mist are less likely to be released from the metal fine particle generating units 30 and 40 and the mist generating unit 50.

In order to suppress the charge of the cover 20, it is preferable to form the cover 20 using a material that does not easily cause charge, for example, a PC (polycarbonate) resin, and to make the material of the cover 20 a material that does not easily cause charge. In this portion, the cover 20 constitutes the outer shell of the dryer 1.

It is also possible to eliminate static electricity from the cover 20 by bringing the cover 20 into contact with the electrodes of the mist generation unit (ion generation unit: charged particle generation unit) 50.

Further, in the first embodiment, the pore diameters of the metal fine particle outlets 20a and 20b are made smaller than the pore diameters of the mist outlets 20c. That is, maintenance of the mist generating unit 50 and confirmation of the state through the mist outlet 20c can be performed more easily, and erroneous entry of fingers, tools, etc. through the metal fine particle outlets 20a and 20b can be suppressed. There is.

Further, in the first embodiment, the metal fine particle outlets (ion outlets) 20a and 20b are formed in the peripheral portion 20d of the mist outlet 20c.

Specifically, the metal fine particle outlet 20a and the metal fine particle outlet 20b are arranged side by side so that the mist outlet 20c is at the center.

That is, on the cover 20, the metal fine particle outlets 20a and 20b and the mist outlet 20c are provided in the width direction of the dryer 1 (left-right direction in FIG. 2), the metal fine particle outlet 20a, the mist outlet 20c, and the metal fine particle outlet 20c. It is formed so as to be arranged in the order of 20b.

With such an arrangement, the negatively charged mist is generated by the negative ions blown out from the metal fine particle outlets (ion outlets) 20a and 20b formed in the peripheral portion 20d of the mist outlet 20c. It is possible to suppress the diffusion (discrete) to the outside.

As a result, the straightness of the mist is improved, the mist can easily reach the hair, and the hair care effect can be further enhanced.

Further, a wall portion 20e is provided on the downstream side and below the mist outlet 20c so as to extend in the mist blowing direction. By providing the wall portion 20e, it is possible to prevent the mist blown out from the mist outlet 20c from diffusing (discrete) downward.

Further, the metal fine particle generation units 30 and 40 and the mist generation unit 50 are the metal fine particle generation unit 30, the mist generation unit 50, and the metal fine particle generation unit 40 in the cavity 9 in the width direction of the dryer 1 (left-right direction in FIG. 2). They are arranged in parallel in the order of.

A shielding plate (partition) 6d is provided between the mist generating section 50 and the metal fine particle generating sections (negative ion generating sections) 30 and 40 adjacent to the mist generating section 50.

Then, as shown in FIG. 4, by arranging the shielding plate 6d so as to extend in the vertical direction of the dryer 1 and the mist blowing direction (horizontal direction in FIG. 4), the metal fine particles and the mist are blown out. It suppresses mixing before being blown out from the outlets 20a and 20b and the mist outlet 20c.

As the metal fine particle generating units 30 and 40, conventionally known ones such as a metal fine particle generating device having a discharge electrode (first electrode) and a discharge counter electrode (second electrode) formed of a conductive metal material are used. Can be used.

Further, as the mist generation unit 50, a conventionally known one can be used. For example, by dew condensation of moisture in the air on the surface of a cooling plate cooled by a Peltier element, dew condensation water is generated, and the dew condensation water is atomized by an electric discharge action to form a very fine mist (minus) of nanometer size. An electrostatic atomizer can be used to generate a negatively charged mist containing ions.

In the first embodiment, the mist generation unit (ion generation unit) 50 is a charged particle generation unit that emits mist (charged fine particle water containing charged particles).

Further, in the first embodiment, a charging portion (charging panel) 1f capable of changing the charging state of the hair is provided. The charged portion 1f is provided in the vicinity of the grip portion 1a. Specifically, the charged portion 1f is formed of a conductive resin (conductive member) exposed on the outer surface of the grip portion 1a.

Here, in the first embodiment, the control unit 10 controls the energizing time of the heater (heating unit) 8, controls the rotation speed of the motor 5b, and is generated by the charged particle generation units 30, 40, 50. By controlling the amount of charged particles generated, the wind in various states can be applied to the hair.

As shown in FIG. 9, the control unit 10 is discharged from the outlet opening (discharge port) 4b by the energization control unit 10a that controls the on / off of the energization to the heater (heating unit) 8 and the air blower unit 5. It is provided with an air volume control unit 10b that controls the air volume of the wind. Further, the control unit 10 includes a charged particle generation amount control unit 10c that controls the generation amount of the charged particles generated by the charged particle generation units 30, 40, and 50 (see FIG. 9).

Further, signals from the switch unit (blower mode selection unit) 16 and the switch unit (blower mode selection unit) 19 are input to the control unit 10.

That is, when the switch unit (blower mode selection unit) 16 or the switch unit (blower mode selection unit) 19 is operated to select a desired ventilation mode (for example, a mode in which strong hot air is discharged), Signals from the switch unit 16 and the switch unit 19 are input to the control unit 10.

Then, when the signals from the switch unit 16 and the switch unit 19 are input to the control unit 10, the energization control unit 10a, the air volume control unit 10b, and the charged particle generation amount control unit 10c operate to obtain a desired ventilation mode. The heater (heating unit) 8 is energized, the rotation speed of the motor 5b, and the amount of charged particles generated are controlled so as to be.

In the first embodiment, the energization control unit 10a controls on / off of energization of the heater (heating unit) 8, and when the energization of the heater (heating unit) 8 is turned off, cold air is used. Is discharged. Further, when the heater (heating unit) 8 is turned on, two types of energization are performed: energization with relatively low electric power and energization with relatively high electric power (see FIG. 13). .. Then, when energization with relatively low electric power is performed, warm air with a relatively low temperature is discharged, and when energization with relatively high electric power is performed, warm air with a relatively high temperature is discharged. It will be discharged. When energized with a relatively low electric power, 600 W of electric power can be energized per second, and when energized with a relatively high electric power, 1200 W of electric power can be energized per second.

Further, as shown in FIG. 13, the air volume control unit 10b controls the rotation speed of the motor 5b, and stops the rotation of the motor 5b (stops the drive of the motor 5b) to blow air by the air blower unit 5. Is stopped. Further, by driving the motor 5b at a relatively small rotation speed, a relatively small amount of air is blown by the blower unit 5. Further, by driving the motor 5b at a relatively high rotation speed, a relatively large amount of air is blown by the blower unit 5.

When a relatively small amount of air is blown, the air volume is preferably 1 m ³ / min or less (for example, 0.7 m ³ / min). In this way, the retention of the hair tips when exposed to the wind can be enhanced (see FIG. 10). On the other hand, when a relatively large amount of air is blown, it is preferable that the air volume is 1 m ³ / min or more (for example, 1.3 m ³ / min). By doing so, it is possible to perform hair styling and drying of a portion other than the hair tips more efficiently. This air volume can be obtained from, for example, the area of the outlet opening (discharge port) 4b, the flow velocity (average velocity) of the air discharged from the outlet opening (discharge port) 4b, and the like.

Further, FIG. 13 exemplifies a case in which the air volume by the air blowing unit 5 is switched in two stages, but as shown in the first embodiment, the air volume is switched in three stages of strong wind, medium wind, and weak wind. In this case, the rotation speed of the motor 5b may be controlled by the rotation speed according to each mode.

Further, the selection of the air volume of 1 m ³ / min or less and the selection of the air volume of 1 m ³ / min or more can be performed by the switch unit 16 which is switched in three steps. For example, when the weak wind mode, and 1 m 3 ^/ min or less air volume can be a 1 m 3 ^/ min or more air volume when the paralytic mode and strong wind mode. In any of the modes of strong wind, medium wind, and weak wind, the air volume should be 1 m ³ / min or more, and when the switch unit provided separately is operated, the air volume should be 1 m ³ / min or less. It is also possible.

Further, the charged particle generation amount control unit 10c controls the voltage applied to the voltage application circuits 12 and 13, and by making the applied voltage relatively low, the amount of charged particles generated is reduced. .. Further, by making the applied voltage relatively high, the amount of charged particles generated is increased. The voltage applied to the voltage application circuits 12 and 13 can be appropriately set in the range of, for example, -1 kV to -3 kV.

Here, in the hair dryer 1 according to the first embodiment, various modes are selected according to the purpose of drying the hair, the treatment, etc., and the part of the hair (the tip, the root, etc.) to be dried, the treatment, etc. You can do it. Then, when each mode is selected, the control as shown in FIG. 12 is performed.

Specifically, when the warm air mode is selected in the mode of discharging an air volume of 1 m ³ / min or more, the air volume control unit 10b controls so that the rotation speed of the motor 5b increases. Further, the energization control unit 10a controls so that the energization to the heater (heating unit) 8 becomes high. Then, the charged particle generation amount control unit 10c controls so that the amount of charged particles generated increases.

When the cold air mode is selected in the mode of discharging an air volume of 1 m ³ / min or more, the air volume control unit 10b controls the rotation speed of the motor 5b to increase. Further, the energization control unit 10a controls so that the energization of the heater (heating unit) 8 is turned off. Then, the charged particle generation amount control unit 10c controls so that the amount of charged particles generated increases.

When the hot / cold mode is selected in the mode of discharging an air volume of 1 m ³ / min or more, the air volume control unit 10b controls so that the rotation speed of the motor 5b increases. Further, the energization control unit 10a controls the energization of the heater (heating unit) 8 so as to alternately repeat high and off at a predetermined cycle. Then, the charged particle generation amount control unit 10c controls so that the amount of charged particles generated increases. In this mode, the cycle of energizing the heater (heating unit) 8 is relatively long, 12 seconds, and the time t1 at which the energization of the heater (heating unit) 8 is high is 5 seconds, and the heater (heating) is used. Part) The time t2 at which the energization to 8 is turned off is set to 7 seconds (see FIG. 13).

On the other hand, when the warm air mode is selected in the mode of discharging the air volume of 1 m ³ / min or less, the air volume control unit 10b controls so that the rotation speed of the motor 5b is reduced. Further, the energization control unit 10a controls so that the energization of the heater (heating unit) 8 is low. Then, the charged particle generation amount control unit 10c controls so that the amount of charged particles generated increases.

When the cold air mode is selected as the mode for discharging an air volume of 1 m ³ / min or less, the air volume control unit 10b controls the motor 5b so that the rotation speed is reduced. Further, the energization control unit 10a controls so that the energization of the heater (heating unit) 8 is turned off. Then, the charged particle generation amount control unit 10c controls so that the amount of charged particles generated increases.

Further, when the hot / cold mode is selected in the mode of discharging the air volume of 1 m ³ / min or less, the air volume control unit 10b controls so that the rotation speed of the motor 5b is reduced. Further, the energization control unit 10a controls the energization of the heater (heating unit) 8 so as to alternately repeat high and off at a predetermined cycle. Then, the charged particle generation amount control unit 10c controls so as to alternately repeat a state in which the amount of charged particles generated is large and a state in which the amount of charged particles is small. In this mode, the cycle of energizing the heater (heating unit) 8 is relatively short, 8 seconds, and the time t3 at which the energization of the heater (heating unit) 8 becomes high is 2 seconds (3 seconds or less). ), The time t4 at which the energization of the heater (heating unit) 8 is turned off is set to 6 seconds (see FIG. 13). In addition, the charged particle generation amount control unit 10c increases the amount of charged particles generated when the heater (heating unit) 8 is energized, so that the heater (heating unit) 8 is charged. The amount of charged particles generated is reduced as a whole when the power is off.

Further, in the first embodiment, when the heater (heating unit) 8 is repeatedly energized in a relatively short cycle, the energizing time for energizing the heater (heating unit) 8 is set to 3 seconds or less within the cycle. At the same time, the product of the electric power input to the heater (heating unit) 8 and the energizing time is set to 1000 W · s or more.

Therefore, the energization control unit 10a of the first embodiment energizes the heater (heating unit) 8 within a predetermined cycle in a state where the heating / cooling mode is selected by the switch unit (blower mode selection unit) 19. Is set to 3 seconds or less, and has a first energization control mode in which the product of the electric power input to the heater (heating unit) 8 and the energization time is controlled to be 1000 W · s or more.

If the energizing time for energizing the heater (heating part) 8 is set to 3 seconds or less, when warm air is applied while holding the hair tips by hand, the hair tips cannot be held by hand due to the heat. Can be suppressed.

Further, if the product of the electric power input to the heater (heating unit) 8 and the energizing time is 1000 W · s or more, the warm air temperature is 60 ° C. or more (hair temperature required for treatment such as straightening hair). It becomes possible to give a treatment effect to the hair.

Therefore, if the hot / cold mode is selected in the mode of discharging an air volume of 1 m ³ / min or less by using the hair dryer 1 according to the first embodiment, the hair tip treatment can be performed more easily.

In the first embodiment, the air volume control unit 10b has a first air flow control mode in which the air volume of the air discharged from the outlet opening (discharge port) 4b is controlled to be 1 m ³ / min or less. ing. Then, when the first ventilation control mode is operating, the first energization control mode is operated.

Further, in the first embodiment, the charged particle generation amount control unit 10c generates a second charged particle whose amount is different from that of the first charged particle generation amount control mode and the first charged particle generation amount control mode. It has a charge particle generation amount control mode. Then, in the state where the first energization control mode is operated, the first charged particle generation amount control mode and the second charged particle generation amount control mode are operated. Further, the second charge particle generation amount control mode is operated at least a part of the time for energizing the heater (heating unit) 8.

At this time, the amount of charged particles generated in the second charged particle generation amount control mode is set to be larger than the amount of charged particles generated in the first charged particle generation amount control mode. That is, the amount of charged particles generated is reduced when the hair is exposed to cold air (when the hair is dry or when the hair temperature is low), which increases the electric resistance value of the hair.

As described above, in the first embodiment, static electricity can be removed more stably by controlling the amount of charged particles generated according to the change in the conductivity of the hair surface.

As described above, in the first embodiment, the hair dryer (heated air blower) 1 is provided with a wind tunnel (air flow path) 4 from the inlet opening (suction port) 4a to the outlet opening (discharge port) 4b. , A housing 3 constituting the outer shell, a blower portion 5 provided in the housing 3, and a blower portion 5 for discharging air sucked from the inlet opening (suction port) 4a from the outlet opening (discharge port) 4b, and provided in the housing 3. A heater (heating unit) 8 for heating the air blown by the air blower unit 5 is provided.

Further, the hair dryer (heating blower) 1 includes a switch unit (blower mode selection unit) 19 for selecting a hot / cold mode in which hot air and cold air are alternately discharged from the outlet opening (discharge port) 4b at a predetermined cycle. It is provided with an energization control unit 10a that controls on / off of energization of the heater (heating unit) 8.

Then, the energization control unit 10a sets the energization time for energizing the heater (heating unit) 8 to 3 seconds or less within a predetermined cycle in a state where the heating / cooling mode is selected by the switch unit (blower mode selection unit) 19. At the same time, it has a first energization control mode in which the product of the electric power input to the heater (heating unit) 8 and the energization time is controlled to be 1000 W · s or more.

In this way, the hair temperature (hair temperature at which hydrogen bonds between hair fibers can be broken) required for treatments such as straightening the habit of hair can be obtained in a relatively short time, and it becomes easier to arrange the hair tips. Therefore, it is possible to further improve the hair treatment effect.

Further, the hair dryer (heated blower) 1 may further include an air volume control unit 10b that controls the air volume of the air discharged from the outlet opening (discharge port) 4b by the blower unit 5. Then, the air volume control unit 10b may have a first air flow control mode for controlling the air volume of the air discharged from the outlet opening (discharge port) 4b to be 1 m ³ / min or less.

Further, the first energization control mode may be operated while the first ventilation control mode is operating.

By doing this, the hair tips are prevented from escaping (too much loosening) due to the wind, so that heat can be transferred to the hair tips more stably, and the hair treatment The effect can be further improved.

Further, a hair dryer (heated blower) 1 is provided in the housing 3 to generate charged particles of charged particles 30, 40, 50, and charged particles generated by the charged particle generation units 30, 40, 50. A charged particle generation amount control unit 10c for controlling the production amount may be further provided.

Then, the charged particle generation amount control unit 10c generates a first charged particle generation amount control mode and a second charged particle generation amount control mode that generates charged particles in an amount different from the first charged particle generation amount control mode. And may have.

Further, in the state where the first energization control mode is operated, the time for operating the first charged particle generation amount control mode and the second charged particle generation amount control mode to energize the heater (heating unit) 8. The second charge particle generation amount control mode may be activated at least for a part of the time.

By doing so, the amount of charged particles generated can be changed according to the state of the hair, and the state of attachment of the charged particles to the hair can be more stabilized. In addition, static electricity can be removed more reliably.

At this time, the amount of charged particles generated in the second charged particle generation amount control mode can be made larger than the amount of charged particles generated in the first charged particle generation amount control mode.

In this way, the amount of charged particles generated can be changed according to the temperature of the hair, and even when the conductivity of the hair surface changes, the state of adhesion of the charged particles to the hair can be made more stable. It will be possible. In addition, static electricity can be removed more reliably.

Although the preferred embodiment of the present invention has been described above, the present invention is not limited to the first embodiment, and various modifications can be made.

For example, as shown in FIG. 14, it is also possible to apply the present invention to the brushed hair dryer 1B as a heating blower.

The hair dryer 1B with a brush is formed in a rod shape, and the user holds the grip portion 1a and applies the brush portion 23 provided on the tip portion 1g to the hair to shape the hair (comb the hair). A plurality of bristle 23a are projected from the brush portion 23.

The metal fine particle generating units 30 and 40 and the mist generating unit 50 are housed therein.

The cover 20B is formed with discharge ports 20a and 20b opened toward the bristle 23a, and the metal fine particles generated by the metal fine particle generation units 30 and 40 and the mist generated by the mist generation unit 50 are obtained. It is discharged to the outside from the discharge ports 20a and 20b and acts on the hair and the skin. A voltage is applied from the circuit unit 24 to the metal fine particle generation units 30 and 40 and the mist generation unit 50.

It is designed to be discharged on Wp.

The motor 7B and the fan 5B are housed in a wind tunnel 9B formed in the case 3B. The motor 7B is rotationally driven by a drive circuit included in the circuit unit 24.

An opening 1h serving as an air intake port is formed on the base end side (lower side in FIG. 14) of the case 3B, and when the fan 5B rotates, air enters the wind tunnel 9B from the outside through the opening 1h. An air flow W that flows in, passes through the wind tunnel 9B, and is discharged toward the brush portion 23 is formed. The air flow W is blown out from the blowout hole (discharge port) 23b formed at the base of the bristle 23a of the brush portion 23.

Further, in order to prevent the release of the metal fine particles from being hindered by the charging of the user, the charged portion (charging panel) 1f is exposed on the surface of the grip portion 1a.

Further, a shielding wall 22B is provided to prevent the mist generated by the mist generation unit 50 from reaching the metal fine particle generation units 30 and 40.

Further, in the first embodiment, as the ion generating part, a metal fine particle generating part that generates metal fine particles and negative ions is illustrated, but a metal fine particle generating part that does not generate metal fine particles and simply generates negative ions may be used. ..

The present invention can also be applied to an ion generator that generates positive ions. As described above, the generation of positive ions is effective when used for hair with artificial hair such as a wig. This is because artificial hair such as wigs tends to be negatively charged, and by supplying positive ions, it is possible to suppress the generation of static electricity.

The amount and energization time may be changed.

Further, the supply amount and supply time of the charged fine particles may be changed according to the hair quality (thickness, length, etc.) of the user.

In addition, the cover, housing, and other detailed specifications (shape, size, layout, etc.) can be changed as appropriate.
