It sprays hair and removes static electricity from the hair.

Japanese Utility Model Publication No. 58-16323

  According to the above hair dryer, ions can be sprayed on the hair (object to be fed). However, not enough ions can be sprayed on the hair. In the hair dryer, the ion generating electrode is exposed to a swirling air flow sent from a fan in the case. Therefore, it is inevitable that the generated ions are diffused in the swirling air flow and the distribution density is reduced. Further, the ions diffused thinly in the air flow come into contact with the air supply passage between the ion generation electrode and the outlet and the surface of a component incorporated in the passage and are neutralized and disappear.

  An object of the present invention is to solve the problem that ions generated in an ion generating unit disappear in the middle of a supply path of an air flow generated by a fan, and to more effectively spray ions to an object to be supplied. It is an object of the present invention to provide an air blower such as a hair dryer that can perform the above-mentioned steps. SUMMARY OF THE INVENTION It is an object of the present invention to prevent hair from being diffused thinly in a swirling air flow sent from a fan, and to be able to effectively supply ions with high distribution density to an object to be supplied. An object of the present invention is to provide a blowing device such as a dryer.

The blower of the present invention is a blower in which a heater 9, a fan 7, and a motor 6 for driving a fan are accommodated inside a cylindrical main body case 1 having a suction port 10 and an air outlet 11. The inside is provided with an ion generator 16 and an ion passage 28 for transferring and guiding the ions generated by the ion generator 16. The outlet grill 31 is provided with an outlet 31 of the ion passage 28 protruding from the outer surface of the outlet grill 21, and the cylindrical surface of the air guide tube 23 forming the ion passage 28 is provided on the outlet grill 21. It is supported by the hole 29.

  The air blower of the present invention includes the ion generator 16 and the ion passage 28 that guides the ions generated by the ion generator 16 to move and guide the outlet 31 of the ion passage 28 to the outer surface of the blowout grill 21. This allows the ions generated by the ion generator 16 to be transferred and guided in a state where the ions are isolated to the outside of the outlet grill 21 by the ion passage 28, so that the ions pass between the ion generator 16 and the outlet 11. It can be prevented from diffusing into the air flow or reducing the distribution density, and can reliably prevent ions from being in contact with the surface of the component incorporated in the main body case and being electrically neutralized. For example, when applied to a hair dryer, ions can be delivered to the hair in a state of high distribution density, so that the hair can be electrically neutralized effectively, and furthermore, moisture can penetrate deep inside the hair and its moisture content And the condition of the hair can be optimized. In addition, when the cylindrical surface of the air guide tube 23 forming the ion passage 28 is supported by the support holes 29 provided in the blowout grill 21, the blowout tube 23 can be firmly fixed and supported by the metal blowout grill 21, so that the blowout is performed. It is possible to prevent the position of the air guide tube 23 from shifting when another object comes into contact with the air guide tube 23 projecting from the outer surface of the grill 21 or when a drop impact is applied. (Claim 1)

The air taken in from the suction port 10 at the rear end of the main body case 1 is pressure-fed and sent forward by the fan 7, and is blown out from the air outlet 11 of the outlet tube 1B attached to the front end of the case. At this time, if the heater 9 is energized, the flow of the air flow in the peripheral portion flowing along the inner surface of the main case portion 1A is heated and hot air is blown out. The outlet tube 1B is a molded product made of polycarbonate.

  An ion generating means for generating negative ions is incorporated in the main body case 1. In FIG. 3, the ion generating means includes a rectifier circuit 13 for half-wave rectifying a current from a commercial power supply (100 V), a pulse generating circuit 14 for converting the rectified current into a pulse current, and a pulse current of, for example, 4 kV. It comprises a transformer 15 for boosting the voltage, an ion generator 16, a diode 17 provided between the transformer 15 and the ion generator 16, and the like. The rectifier circuit 13 and the pulse generating circuit 14 are mounted on a circuit board 18, and the circuit board 18 and the step-up transformer 15 are arranged in a space formed by cutting out the insulating frame 8 for the heater 9. These electric components are incorporated into the main body case 1 from the suction port 10 side together with the motor 6 and the fan 7. At this time, the ion generator 16 is also installed at the same time. According to the above-described ion generation means, the current from the commercial power supply (100 V) is half-wave rectified by the rectifier circuit 13 and then converted into a pulse current by the pulse generation circuit 14. Next, the pulse current is stepped up by the transformer 15, and a high voltage stepped up to, for example, 4 kV is applied to the center electrode 34, and electrons are emitted from the electrode 34 to the counter electrode 35. As a result, oxygen, minute water droplets, dust and the like in the air are negatively charged and negatively ionized.

  In FIG. 1, a straightening tube (inner frame) 20 and a blowout grill 21 are incorporated inside the outlet tube 1 </ b> B, and the ion generator 16 is supported by the straightening tube 20, and an air flow generated by the fan 7 is generated.

The rectifying cylinder 20 is formed in a circular cross section, and is made of a polycarbonate plastic molded article integrally formed with a rectifying wing 22 radially provided at an inner front end thereof and an air guide cylinder 23 provided at the center of the cylindrical wall. After fitting the outlet grill 21 into the step portion 24 provided on the inner surface of the outlet tube 1B, the outlet grill 1 is fixed to the outlet grill 1B by fixing the rectifying tube 20 inside the outlet tube 1B so that the outlet grill 21 is not movable. It can be handled as one unit part. In the present embodiment, the rectifying cylinder 20 and the outlet cylinder 1B are internally fitted and fixed around the entire circumference, but the invention is not limited to this. A dent is formed in several places of the outlet cylinder 1B, and the rectifying cylinder 20 fitted into the recess is formed. The rectifying cylinder 20 may be fixed via claws integrally formed with the rectifying cylinder 20 or the rectifying cylinder 20 and the outlet cylinder 1B may be ultrasonically welded. The blowout grill 21 is provided to regulate the contact with the heater 9 and the motor 6 as before, but also serves to prevent the contact with the ion generating circuit. The rectifying vanes 22 rectify the swirling airflow generated by the fan 6 into a linear airflow.

  In FIG. 4, the air guide tube 23 is formed by a tapered first cylindrical portion 26 and a second cylindrical portion 27 that continuously projects forward from a small-diameter end in front of the first cylindrical portion 26. The ion generator 16 is incorporated in an ion passage 28 defined by the first cylindrical portion 26. The negative ions generated by the ion generator 16 are supplied by an air flow passing through the ion passage 28. In order to prevent the air flow including the negative ions from being diffused by the air flow blown out from the blowout grill 21. The front end of the second cylindrical portion 27 projects outward from the outer surface of the blowout grill 21. More specifically, a support hole 29 provided in the center of the blowout grill 21 supports the rear end peripheral surface of the second cylindrical portion 27 on the outlet side of the air guide tube 23, and almost all of the second cylindrical portion 27. Project from the front surface of the blowout grill 21. Further, the front end of the second cylindrical portion 27 projects further forward than the opening surface of the outlet 11. Reference numeral 30 denotes an inlet of the air guide tube 23, and 31 denotes an outlet of the air guide tube 23.

  4 to 6, the ion generator 16 includes an electrode holder 33, a central electrode 34 fixed to the center of one side of the electrode holder 33, a counter electrode 35 surrounding the central electrode 34, and a central electrode 34. A dielectric 36 that insulates and blocks the space between the opposing electrodes 35. The electrode holder 33 is made of a plastic molded article integrally formed with a multi-stage shaft-shaped boss portion 37 and a radial holding arm 38 provided on the peripheral surface of the boss portion 37, and has ozone resistance and heat resistance. Moreover, it is molded with a plastic having excellent insulating properties, for example, polyphenylene sulfide. A cylindrical wall 39 for supporting the counter electrode 35 is formed on one side of the boss 33, and an escape recess 40 is formed on the other side. The electrode holder 33 can be positioned and fixed to the air guide tube 23 by fitting and holding the holding arm 38 into the concave portion 41 provided on the inner surface of the first cylindrical portion 26. Specifically, as described above, the holding arm 38 of the electrode holder 33 assembled in the main body case 1 together with the electric components constituting the ion generating means is fitted and fixed in the concave portion 41. Thereafter, the outlet tube 1B in which the rectifying tube 20 and the blowout grill 21 are unitized is attached to the main case portion 1A, and the joining surfaces of the both are ultrasonically welded. When the outlet tube 1B is attached to the main case portion 1A, the claw portion provided at the rear end of the rectifying tube 20 engages with the main case 1A. This serves to firmly fix the tube 20 to the outlet tube 1B. The ion generator 16 (electrode holder 33) is not connected to other electrical components and assembled from the suction port 10 side of the main case portion 1A, but is assembled in advance into the air guide tube 23 and unitized by four members. A lead wire may be connected to the other electrical component incorporated in the case 1A, and then the unit may be welded and fixed to the main case 1A.

  The center electrode 34 includes a discharge needle 43 formed of tungsten having a small discharge resistance and a positioning boss 44 fixed to the rear end of the discharge needle 43. The front end of the discharge needle 43 is sharpened to form a discharge portion 45. . The discharge needle 43 is positioned on the center axis of the electrode holder 33 by fitting the positioning boss 44 into the mounting hole at the center of the electrode holder 33. As shown in FIG. 5, the counter electrode 35 is formed of a press fitting made of a thin plate made of copper or iron, and has a ring-shaped electrode portion 46 with one portion of the peripheral surface cut off, and a rear edge of the electrode portion 46. And four mounting legs 47 extending rearward from the body. The electrode portion 46 is externally fitted to the cylindrical wall 39 having a circular cross section of the electrode holder 33, and the mounting leg 47 is bent and fixed to the step on the peripheral surface so that the electrode portion 43 is concentrically positioned with respect to the central electrode 34. It can be fixed in the state where it was done. In this mounting state, the front ends of the electrodes 34 and 35 are located on the same plane including the opening surface of the cylindrical wall 39 and orthogonal to the central axis of the central electrode 34 (see FIG. 4).

  The dielectric 36 is formed in a cylindrical shape from a material having high insulating properties such as mica, glass, and ceramics, and one end thereof is fitted and fixed to the inner surface of the cylindrical wall 39 to be integrated with the electrode holder 33. In this fixed state, the counter electrode 35 and the dielectric 36 are arranged concentrically around the center electrode 34. The front cylinder end of the dielectric 36 faces the front end portion of the first cylinder 26 and forms an orifice portion R between the dielectric 36 and the first cylinder 26. In order to prevent irregular discharge from occurring between the center electrode 34 and the counter electrode 35 and effectively generate negative ions, the dielectric 36 protrudes largely forward from the discharge portion 45 of the center electrode 34. As shown in FIG. 1, the center electrode 34, the counter electrode 35, and the transformer 15 are connected to each other by a lead wire 48 so as to prevent a spark from being generated between portions where the lead wire 48 is soldered. The electrode 34 and the lead wire 48 are accommodated in a clearance recess 40 behind the boss 37 and are sealed with an insulating sealing material 49 filling the recess 40. An insulating adhesive such as silicon can be used as the sealant.

  The cross-sectional area of the ion passage 28 in the second cylindrical portion 27 is sufficiently smaller than the cross-sectional area of the air flow in the outlet cylinder 1B. Therefore, even if the second cylindrical portion 27 is positively charged, the charged state can be neutralized in a very short time, so that more negative ions can be supplied. In this embodiment, when the diameter of the ion passage 28 in the second cylindrical portion 27 is 9 mm, the diameter of the inner surface of the rectifying cylinder 22 is 53 mm.

  In the hair dryer, as shown in FIG. 8, a tapered (or may be expanded) cylindrical nozzle 50 may be added to the front end side of the outlet tube 1 </ b> B, that is, the outlet 11, if necessary. There is. A plastic inner cylinder 51 is fixed to the inner surface of the nozzle 50, and the inner cylinder 51 is detachably attached to the outlet 11 of the outlet cylinder 1B. Inside the inner cylinder 51, a leaf-shaped straightening vane 52 having a leaf shape, and a holding boss 53 facing the front and rear are provided integrally at the center thereof. A guide tube 55 that is long in the front-rear direction is provided inside the holding boss 53 by loading a separately formed passage tube 54 from the front side. The front end of the guide passage 55 projects slightly forward from the opening surface of the nozzle 50. The cross-sectional area of the guide passage 55 is sufficiently smaller than the cross-sectional area of the air flow on the inner surface of the nozzle 50. Therefore, as described in the ion passage 28, even if the passage cylinder 54 is positively charged, the charged state can be neutralized in a very short time, and thus more negative ions can be supplied. . Of course, if the passage cylinder 54 is negatively charged, there is no problem because the negative ions are not neutralized.

  As shown in FIG. 8, when the nozzle 50 is attached to the outlet 11 of the outlet tube 1 </ b> B, the rear end opening surface of the guide passage 55 is adjacent to the outlet 31 of the ion passage 28. Therefore, the negative ions coming out of the ion passage 28 are guided to the guide passage 55 and are fed to the outside of the outlet 56 at the front end of the nozzle. The nozzle 50, its inner cylinder 51, and the passage cylinder 54 are each made of a molded product made of polycarbonate. The rear end of the guide passage 55 may be formed so as to have a tapered shape extending rearward so as to cover the front end of the ion passage 28. In this case, if a slight gap is formed between the rear end of the guide passage 55 and the front end of the ion passage 28, it is possible to reliably prevent the two from interfering with each other when the nozzle 50 is attached and detached, and to prevent breakage.

  According to the hair dryer configured as described above, the negative ions generated by the ion generator 16 can be supplied to the outlet 11 in a state where the negative ions are sealed in the ion passage 28, so that the negative ions are blown to the ion generator 16. Diffusion into the main airflow passing through the wind guide between the outlet 11 and the distribution density of the air can be prevented from lowering, and components such as a case and a blowout grill 21 in which negative ions are incorporated in the wind guide. Can be reliably prevented from being electrically neutralized by contacting the surface. Further, since the air guide tube 23 protruding from the outer surface of the outlet grill 21 comes into contact with the ground and the like before other portions, it is advantageous in that the ground and the like can be prevented from contacting the high-temperature outlet grill 21. is there. The air guide tube 23 also serves as a protective body for the dielectric 36. Further, since the outlet 31 of the ion passage 28 is located at the center of the outlet 11 and projects from the outlet grill 21 and faces the opening surface of the outlet 11 or projects forward from the opening surface, the outlet 31 of the ion passage 28 The negative ions released from the outlet 31 are wrapped in the center of the airflow blown out from the outlet 11 and can reach the hair. A straightening vane 22 is provided immediately before the air outlet 11 to prevent the flow of the main air blown out from the air outlet 11 from turning, so that the negative ions coming out of the ion passage 28 diffuse into the main air flow. And the amount of negative ions reaching the hair is improved. The negative ions allow moisture to penetrate deep into the hair, increase the moisture content, and optimize the condition of the hair.

  When the nozzle 50 is connected to the outlet 11 of the outlet tube 1B and used, the negative ions coming out of the outlet 31 of the ion passage 28 are transferred to the outlet 56 of the nozzle 50 through the guide passage 55 in the nozzle 50. Since it is possible to prevent the negative ions from diffusing into the main airflow passing through the inside of the nozzle, it is possible to wrap the periphery of the flow of the negative ions with the airflow blown out from the outlet 56 and to feed the negative ions. The ions can be effectively delivered to the hair with a high distribution density. In the hair dryer of this embodiment, the negative ions were to be supplied. However, when the ozone generated at the same time as the generation of the ions was to be supplied, the above-described functions and effects were similarly exhibited. it can. However, ozone is sent for the purpose of deodorization.

  FIG. 10 shows another embodiment of the baffle tube 23. Here, the air guide tube 23 is formed as a straight double tube, and the ion passage 28 and the air passage 58 are provided inside and outside thereof. The holding arm 38 of the electrode holder 33 was omitted, and the boss 37 was fitted and fixed in a mounting hole 59 at the rear end of the ion passage 28. The protruding end of the inner cylindrical wall 60 that defines the ion passage 28, that is, the outlet 31 of the ion passage 28 is located at approximately the same front and rear position as the protruding end surface of the dielectric 36, and the air flow passing through the air passage 58 Can be sent reliably.

  FIG. 11 shows an embodiment in which the present invention is applied to a hair blower (blower). Here, a fan 7, a motor 6, a heater 9, and the like are housed inside a linear cylindrical main body case 1. A suction port 10 is provided at the rear end on the right side of the main body case 1, and a brush body 65 selected and used as an attachment is detachably mounted on the air outlet 11 on the left front end. A metal outlet grill 21 and an inner frame 20 are fixed inside the outlet 11, and the ion generator 16 is supported by a baffle tube 23 provided inside the inner frame 20. That is, the blow grill 21, the inner frame 20, the air guide tube 23, and the ion generator 16 are fixedly supported on the main body case 1 side. The outlet 31 of the air guide tube 23 projects from the outer surface of the outlet grill 21, but is flush with the opening surface of the outlet 11. Even with this configuration, since the negative ions are not adsorbed to the blowout grill 21 and other components, negative ions having a high distribution density can be supplied to the hair. Further, since the outer periphery of the front end of the baffle 23 is supported by the inner periphery of the support hole 29 provided in the center of the blowout grill 21, even if an external force such as a drop impact is applied, the baffle 23 can be damaged. Can be prevented. A curved passage cylinder 54 having a guide passage 55 is fixed inside the brush body 65 via a guide passage fixing support arm. The brush body 65 has a plurality of bristles 72 arranged in a row in the axial direction, and a group of small holes for sending out a main air flow between the bristles 72, that is, a blowing hole 66. The passage tube 54 has an inlet connected to the outlet 31 of the air guide tube 23, and the outlet is open at a central portion of a number of outlets 66. The brush body 65 can be detached by pressing a detachable button (not shown). A power switch 3 and an ion switch 4 are provided on the upper surface of the main body case 1. The concept of the nozzle 50 in the present invention includes an attachment for a hair blower as in this embodiment.

  As described above, when the cross-sectional areas of the ion passage 28 and the guide passage 55 are made sufficiently smaller than the cross-sectional area of the air flow generated by the fan 7 (the cross-sectional area of the main body case 1) and the cross-sectional area of the brush body 65. Even if the peripheral walls of the ion passage 28 and the guide passage 55 are positively (or negatively) charged, the charged state is neutralized in a very short time by the negative ions (or positive ions) generated by the ion generator 16. Yes, so many negative (or positive) ions can be delivered to the object immediately. The comparison between the cross-sectional area of the ion passage 28 and the guide passage 55 and the cross-sectional area of the air flow generated by the fan 6 or the cross-sectional area of the brush body 65 is grasped as a difference between the inner surface areas of the two passages. In other words, what is necessary is just a physical quantity that means a difference in the total amount of ions when the negative ions (or positive ions) are neutralized and reduced on the inner surface of the passage.

  FIG. 12 shows another embodiment in which the invention is applied to a hair blower (blower). The basic structure of the hair blosser in this embodiment is the same as that of the hair blosser described with reference to FIG. 11, except that the baffle tube 23 in the embodiment of FIG. The point provided in the passage cylinder 54 is significantly different from the previous embodiment. Specifically, the inlet side of the passage tube 54 is made to protrude outward from the connection opening of the brush body 65 with the main body case 1, and the brush body 65 is connected to the main body case 1. Was formed around the ion generator 16 to form the ion passage 28 with the passage tube 54. Reference numeral 67 denotes a support arm protruding from the outer surface of the passage tube 54 for holding the position of the passage tube 54 at the center of the tube. In this case, the ion generator 16 is configured by accommodating each of the pair of discharge needles 43 and 68 in a glass tube 69.

  According to the hair blower configured as described above, the ion passage 28 does not exist when the brush body 65 selected and used as an attachment is removed from the main body case 1. However, when the brush body 65 is mounted on the main body case 1, the passage cylinder 54 covers around the ion generator 16, and the generated negative ions are transferred between the bristle 72 of the brush body 65 through the guide passage 55. Can be discharged from the central portion of the blowout hole 66 formed at the bottom. In addition, since a part of the air flow generated by the fan 7 is taken into the guide passage 55 and negative ions are supplied by the air flow passing through the guide passage 55, the ion generator 16 and the outlet of the guide passage 55 are connected to each other. Despite being far away, it can reliably send and release negative ions. Further, since the extended portion of the passage tube 54 is fixed and supported by the support hole 29 of the blowout grill 21, the passage tube 54 moves freely when a drop impact is applied, so that the passage tube 54 surrounds the discharge needles 43 and 68. 69 can be reliably prevented from coming into contact. The number of parts can be reduced by the amount that the air guide tube 23 can be omitted, and the manufacturing cost can be reduced by that much. In the present embodiment, the brush body 65 selectively used as an attachment has a detachable structure, but is handled as a part of the main body case 1. The one corresponding to the ion passage 28 is the guide passage 55, and the one corresponding to the outlet 11 is the blowout hole 66. When the brush body 65 as shown in FIG. This is because it is possible to protrude from the outlet grill 21 and to prevent the adsorption of negative ions to the outlet grill 21 and other components as a result.

  In FIG. 13, a hook-shaped ion passage 28 is arranged from the upper outer surface of the main body case 1 to the outlet 11, and the ion generator 16 is provided near the inlet 30. The ion generating section 16 includes a ring-shaped counter electrode 35 fixed to the inner surface of the ion passage 28 and a needle-shaped electrode 70 disposed on the center axis of the counter electrode 35 at a position away from the opening surface of the counter electrode 35. It is configured so that ion wind can be generated effectively. In this embodiment, instead of using the air flow generated by the fan 7 to transfer the negative ions, the negative ions are sent to the outlet 31 only by the sending action of the ion wind generated by the corona discharge. . The end of the passage cylinder 71 that defines the ion passage 28 on the outlet 31 side is supported by the blowout grill 21, and the outlet 31 projects out of the central portion of the blowout grill 21. A passage tube 54 is provided inside the nozzle 50 mounted on the outlet 11 to form a guide passage 55 that is continuous with the ion passage 28.

  In addition to the above-described embodiment, the ion passage 28 may be formed as a linear passage in the front-rear direction. The ion passage 28 or its outlet 31 can be arranged so as to be deviated at a position other than the center of the outlet 11. For example, the ion passage 28 can be partitioned so as to be deviated to one location on the inner surface of the outlet wall 1B. The ion passage 28 may be bent or bent at an intermediate portion thereof. The ion passage 28 can be formed by an elastically deformable tube, and the outlet 31 can be constituted by a plurality of openings.

  The outlet tube 1B can be formed integrally with the main body case 1. In this case, after the rectifying cylinder 20 and the ion generator 16 are assembled into the main body case 1 from the suction port 10 side, the insulating frame 8 in which the heater 9, the circuit board 13 and the transformer 14 are assembled is attached to the main body case 1. It is good to put together. In this case, the outlet grill 21 is fitted and fixed from the outlet 11 side. In the embodiment, the case where negative ions or ozone is supplied has been described, but the supply target may be positive ions. The ion generator 16 has a creeping discharge type structure in which a discharge electrode and an induction electrode are arranged on the front and back of a plate-shaped insulator (dielectric) made of mica, ceramic, or the like, or two needle electrodes are opposed to each other. The electrode structure can be changed to an arranged electrode structure, and the structure is not limited as long as ions can be generated. When generating positive ions, the diode 17 in FIG. 3 is connected in a state where it is inverted left and right. The blower of the present invention also includes devices such as a hair blower and a foot dryer. Further, a blower without a heater such as a fan is also included in the blower of the present invention.
