Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a blower represented by a hair dryer, and more particularly to a blower provided with means for generating ions.
[0002]
[Prior art]
This type of hair dryer is known from Japanese Utility Model Publication No. 58-16323. In this case, a high voltage needle electrode is provided in the case body, ions and ozone are generated by applying a high voltage to the electrode, and the ions and ozone generated on the hair are placed on the wind generated by the fan. It is configured to spray.
[0003]
[Problems to be solved by the invention]
According to said hair dryer, ion can be sprayed on hair. However, a sufficient amount of ions cannot be sprayed onto the hair. In the hair dryer, it is inevitable that the generated ions are diffused in the swirling air flow by the swirling air flow sent from the fan, and the distribution density decreases toward the outlet. The ions diffused thinly in the air flow contact with the air passage between the ion generating electrode and the outlet and the surface of the component incorporated in the passage and are neutralized and disappear.
[0004]
In particular, in the case of a hair blosser that is used by connecting a brush unit to the air outlet of the case body, the number of negative ions that disappear while passing through the air guide and the brush unit is large, and the degree of depletion is reduced to ions. It has been confirmed that it reaches about half of the number generated by the generation electrode. As described above, in the conventional example including the ion generation electrode, there is a large gap between the number of negative ions generated by the ion generation electrode and the number of negative ions that can actually reach the hair. There was room for improvement in that the loss of ions was high and negative ions could not be effectively delivered to the hair.
[0005]
An object of the present invention is to prevent the ions generated in the ion generating part from disappearing in the air flow path in the main body case, and to more effectively spray ions onto the object (hair). It is to provide a blower.

On the front and rear surfaces of the handle 2, there are provided a power switch knob 3 serving both as air flow control and a heater switch, and an ion switch knob 4 for turning on / off the energization of the ion generator 15. The handle 2 accommodates a switch that is switched by the previous switch knobs 3 and 4. As indicated by an imaginary line, the handle 2 is foldably connected to the main body case 1.
[0017]
As shown in FIG. 2, the blower unit includes a motor case 5, a fan 6 and a motor 7 that are assembled to the motor case 5, and a heater 9 that is spirally wound around an insulating frame 8 that is assembled in a cross shape. The fan 6 is rotationally driven in one direction, pressurizes air sucked from the suction port 10 at the rear end of the main body case 1 and blows it out from the air outlet 11 of the wind conductor 1A attached to the front end. At this time, if the heater 7 is energized, warm air is blown out. The wind conductor 1A is made of a molded product made of polycarbonate.
[0018]
The hair dryer incorporates ion generation means for generating negative ions. As shown in FIG. 2, the ion generating means includes a circuit board 13 on which a rectifier circuit and a pulse generating circuit are mounted, a boosting transformer 14, an ion generating unit 15, and the like. 14 is arranged in a space formed by cutting out the insulating frame 8 for the heater 9, and the ion generating part 15 is incorporated in the wind conductor 1A.
[0019]
In FIG. 3, a rectifying cylinder 17 and a metal blowing grill 18 are incorporated in the inside of the wind conductor 1 </ b> A, and the previous ion generator 15 uses the rectifying cylinder 17 to generate an air flow generated by the fan 6. It is held so as to be located at the center. The rectifying cylinder 17 is a polycarbonate in which a cylindrical wall 19 having a circular cross section, a rectifying blade 20 provided radially at the front end of the rectifying cylinder 17 and a cylindrical body 54 forming an ion passage 21 provided in the center of the cylindrical wall 19 are integrally formed. Made of plastic molded product. In FIG. 5, the blow grill 18 is formed by a press-molded product including concentric circular arc ribs 18 a and two types of long and short radial straight ribs 18 b. After fitting the blow-out grill 18 inside the wind conductor 1A, the rectifying cylinder 17 is fitted and fixed to the wind conductor 1A, so that these three components can be handled as one unit component. The rectifying blade 20 of the rectifying cylinder 17 and the long linear rib 18b in the assembled state of FIG. 6 are overlapped in the front-rear direction, thereby rectifying the air flow generated by the fan 6 and the rectifying blade 20 The subsequent linear air flow is prevented from being disturbed by the linear rib 18b.
[0020]
3 to 5, a plastic cylindrical body 54 includes a tapered first tapered cylindrical portion 23 and a second cylindrical portion 24 that protrudes forward continuously from a small diameter front end of the first cylindrical portion 23. The ion generating part 15 is incorporated in the inside of the first cylinder part 23. The front end of the second cylindrical portion 24 protrudes forward and outward from the opening surface of the air outlet 11 in a state of being located at the center of the air outlet 11 of the wind conductor 1A. Therefore, even when the hair dryer is placed with the air outlet 11 facing the floor surface, the second cylindrical portion 24 comes into contact with the floor surface, and there is a gap between the air outlet 11 and the floor surface. Can be formed. Reference numeral 40 in FIG. 1 is an inlet for introducing a part of the wind generated by the fan 6 into the cylinder 54, and 41 is an ion that is transferred by the wind passing through the cylinder 54 together with the wind. It is an outlet for ions to blow out. Reference numeral 52 denotes a wind intake opening formed by the notch 55 of the first tube portion 23. In the first tube portion 23, a wind intake body 51 that is located at a position facing the notch 55 and forms a higher angle than the first tube portion 23 is formed integrally with the first tube portion 23. As shown in FIGS. 3 to 6, the wind intake body 51 extends to the maximum diameter portion of the cylindrical body 54, that is, to a position positioned radially outward from the rear end 56 of the first cylindrical portion 23. . As a result, wind can be introduced not only from the inlet 40 but also from the wind intake opening 52, so that the amount of wind flowing through the cylindrical body 54 can be increased, and negative ions generated by the ion generator 15 can be effectively removed. It can be fed to the object (hair). Further, as shown in FIG. 2 or FIG. 3, by extending the outer portion of the wind intake body 51 to a position located radially outward from the outer portion of the transformer 14 as a drive source, the cylindrical body 54 is provided. Even if the inlet 14 of the cylinder 54 and the front end surface of the drive source are arranged close to each other in order to reduce the size of the main body 14 and the transformer 14, the wind intake body protrudes outward from the outer portion of the drive source (transformer 14). Due to the presence of 51, the wind can be reliably taken into the cylinder 54. In the present embodiment, the inlet 40 of the cylindrical body 54 and the front end surface of the drive source are arranged in close proximity to each other, but with the same arrangement, the wind intake opening 52 and the wind intake body 51 are provided. According to the present embodiment in which the amount of negative ions blown from the outlet 41 is 5,000 to 10,000, the wind intake opening 52 and the wind intake body 51 are formed in the cylinder 54. For example, the amount of negative ions blown out from the outlet 41 was 500,000 to 1,000,000, almost 100 times larger.
[0021]
The cross-sectional area of the ion passage 21 in the second cylindrical portion 24 is sufficiently smaller than the cross-sectional area of the air flow in the wind conductor 1A. Therefore, even if the second cylinder portion 24 is positively charged, the charged state can be neutralized in a very short time, and therefore more negative ions can be fed. Also in the relationship between the nozzle body 34 and the passage cylinder 29 described later, negative ions can be effectively fed for the same reason. Incidentally, in this embodiment, when the diameter dimension of the ion passage 21 in the second cylinder portion 24 is 9 mm, the diameter dimension of the inner surface of the rectifying cylinder 17 is 53 mm.
[0022]
3 and 5, the ion generator 15 includes an electrode holder 25, a needle electrode 26 fixed to the center of the electrode holder 25, a surrounding electrode 27 surrounding the needle electrode 26, and the needle electrode 26. And an insulating cylinder 28 that divides the space between the electrode 27 and the surrounding electrode 27. The electrode holder 25 is made of a plastic molded product in which a boss portion 30 and a radial holding arm 31 provided on the peripheral surface of the boss portion 30 are integrally formed, have ozone resistance and heat resistance, and have insulating properties. It is molded with a plastic excellent in quality, such as polyphenylene sulfide (PPS). The electrode holder 25 can be integrated with the rectifying cylinder 17 by fitting and fixing the holding arm 31 in a recess 23 a (see FIG. 5) provided on the inner surface of the first cylinder portion 23.
[0023]
A needle electrode 26 is fixed to the center of the boss 30 and a peripheral electrode 27 is mounted concentrically on the peripheral surface of the boss 30. In this mounted state, the front ends of both electrodes 26 and 27 are in the same plane. Located in. The insulating cylinder 28 is formed in a cylindrical shape with a material having high insulating properties such as mica, glass, ceramics and the like. In a state in which the insulating tube 28 is fitted and fixed in the recess at the front end of the boss portion 30, the front end of the insulating tube 28 is provided so as to protrude largely forward from the front ends of the needle electrode 26 and the surrounding electrode 27. It faces the front end of the cylindrical portion 23. Thus, when the insulating cylinder 28 protrudes largely forward, it is possible to prevent the needle-like electrode 26 and the surrounding electrode 27 from generating a spark and to effectively generate negative ions. As shown in FIG. 3, the acicular electrode 26, the surrounding electrode 27 and the transformer 14 are connected by lead wires, but in order to prevent sparks from occurring between the portions where the lead wires are soldered, the acicular electrodes 26 and the lead wire are sealed with an insulating adhesive 32 filled in a recess on the rear side of the boss 30.
[0024]
FIG. 8 shows an outline of an electric circuit for generating negative ions. In this case, the current from the commercial power supply (100V) is half-wave rectified by a rectifier circuit and then converted into a pulse voltage / current by a pulse generation circuit. Next, the pulse voltage / current is boosted by the transformer 14, and a high voltage boosted to, for example, 4 Kv is applied to the needle electrode 26, and electrons are emitted from the needle electrode 26 toward the surrounding electrode 27. As a result, oxygen, minute water droplets, dust and the like in the air are negatively charged and negatively ionized. The diode in FIG. 8 is provided to obtain only a negative output in the needle electrode 26, but can be omitted. In that case, positive ions and negative ions are generated alternately. In addition, ozone is also generated as a by-product at the same time as negative ions are generated, but in order to extremely reduce the generation of ozone, a resistance is provided between the diode and the needle electrode 26 in FIG. Also good.
[0025]
In the hair dryer, as shown in FIG. 1, a nozzle 33 may be added to the front end side of the wind conductor 1A, that is, the air outlet 11 as needed. The nozzle 33 includes a nozzle body 34 having a tapered cylindrical shape (which may be widened forward) and an inner cylinder 35 attached to the inner surface of the nozzle body 34, and is detachable from the air outlet 11 on the body case 1 side. It is attached to. A leaf-shaped rectifying blade 36 is provided inside the inner cylinder 35, and a holding boss 37 facing forward and backward is integrally provided at the center thereof. A passage cylinder 29 is loaded into the hollow inside of the holding boss 37. A guide passage 38 that runs in the front-rear direction is provided. The sectional area of the guide passage 38 is sufficiently smaller than the passage sectional area of the air flow in the nozzle body 34. Therefore, as described in the ion passage 21, even if the passage cylinder 29 is positively charged, the charged state can be neutralized in a very short time, so that more negative ions can be fed. .
[0026]
As shown in FIG. 1, the rear end opening surface of the guide passage 38 is provided adjacent to the outlet 41 of the ion passage 21 in a state where the nozzle 33 is mounted on the air outlet 11 of the wind conductor 1A. The negative ions emitted from the nozzle 33 are transferred and guided to the opening surface of the air outlet 39 at the front end of the nozzle 33. The nozzle body 34, the inner cylinder 35, and the passage cylinder 29 are each made of a molded product made of polycarbonate. Each of the nozzle body 34 and the inner cylinder 35 is molded from a transparent or translucent plastic material, and a glossy decorative sheet 46 is loaded between the passage cylinder 29 and the transparent holding boss 37. Since the decoration sheet 46 can be seen through the holding boss 37, the design effect of the nozzle 33 can be improved.
[0027]
According to the hair dryer configured as described above, the negative ions generated in the ion generator 15 can be supplied to the outlet 11 in a state of being sealed in the ion passage 21, so that the negative ions are blown into the ion generator 15 and the blower. It can be prevented from diffusing into the main air flow passing through the air guide portion between the outlet 11 and the distribution density thereof being lowered, and negative ions are incorporated into the air guide portion and parts such as the blow grill 18 It is also possible to reliably prevent electrical neutralization in contact with the surface. Furthermore, since the outlet 41 of the ion passage 21 is located at the center of the outlet 11 and protrudes forward from the opening surface of the outlet 11, the negative ions released from the outlet 41 of the ion passage 21 are discharged from the outlet 11. Wrapped in the center of the air flow blown out from the hair can reach the hair. Since the rectifying blade 20 is provided immediately before the air outlet 11, the main air flow blown out from the air outlet 11 can be prevented from turning, so that negative ions emitted from the ion passage 21 diffuse into the main air flow. The amount of negative ions reaching the hair is also improved in this respect. With negative ions, moisture can penetrate deeply into the hair and the moisture content can be increased to optimize the condition of the hair. The cylindrical body 54 is preferably in the vicinity of the air outlet 11, but may be located at the center of the main body case as long as it is in front of the fan 6 (downstream side of the wind generated by the fan 6). . The outlet 41 may also be located behind the outlet 11. In short, any configuration may be used as long as the ion generator 15 is surrounded by the cylindrical body 54.
[0028]
When the nozzle 33 is connected to the air outlet 11 of the wind conductor 1 </ b> A and used, negative ions emitted from the outlet 41 of the ion passage 21 are transferred to the air outlet 39 of the nozzle 33 through the guide passage 38 in the nozzle 33. Therefore, the negative ions can be prevented from diffusing into the main air flow passing through the inside of the nozzle, and the periphery of the negative ion flow can be wrapped in the air flow blown out from the air outlet 39 and fed. Ions can be effectively delivered to the hair with a high distribution density. In the hair dryer of this embodiment, negative ions are targeted for feeding, but the above-mentioned effects are also exhibited when ozone generated simultaneously with the generation of ions is targeted for feeding. it can. However, ozone is supplied for the purpose of deodorization. The first cylinder part 23, the second cylinder part 24, and the passage cylinder 29 for feeding negative ions are formed by using a lower (minus) material than the other passage constituent members. It is preferable. When the material is selected in consideration of the charging train in this way, at the time of use, the passage constituent member is negatively charged due to contact friction at the joint portion between the previous cylindrical members 23, 24, 39 and other passage constituent members. Therefore, it is possible to prevent the negative ions flowing along the passage constituent member from being adsorbed on the passage wall, and to reduce the depletion of negative ions in the middle of the feeding path.
[0029]
9 to 10 show another embodiment of the present invention. In each of the other embodiments, only points that are significantly different from the previous embodiment will be described, and the same members as those in the previous embodiment will be denoted by the same reference numerals, and description thereof will be omitted. In the hair dryer of FIG. 9, the point which forms the cylinder 54 which comprises the ion channel | path 21 in the straight tube | pipe which runs in the front-back direction, and the point which attaches the nozzle 33 to the wind conductor 1A differ from the previous Example. Inside the ion passage 21, the ion generating part 15 is incorporated as in the previous embodiment. Also in this embodiment, the wind intake body 51 is provided at a position facing the notch 55 so as to form a higher angle than the angle of the cylindrical body 54 and the maximum diameter portion 58 of the cylindrical body 54 (because it is a straight tube, the cylindrical body 54). The same part is taken from the front end to the rear end, and the portion extends radially outward from the same position. Further, the outer portion of the intake body 51 is extended to a position positioned radially outward from the outer portion of the transformer 14 as a drive source stored in the main body case 1.
[0030]
In FIG. 10, unlike the case in which the cutout 55 is formed in the cylindrical body 54 and the wind intake body 51 is formed on the downstream side in the wind flow direction as in the first embodiment, the diameter is substantially equal to that of the transformer 14. The rear end 56 of the first cylindrical portion 23 is not provided with a notch, and only the wind intake body 51 is integrally formed and extended in all circumferential directions. That is, the cylindrical body 54 has a bell shape in which the rear end protrudes radially outward from the outer portion of the transformer 14. In the present embodiment, the outer portion of the transformer 14 is all located within the projection plane of the cylindrical body 54 as viewed from the suction port 10 side at the rear end of the main body case 1. Also with this configuration, the wind flowing along the outer portion of the transformer 14 can be actively taken into the cylindrical body 54, and the air volume in the cylindrical body 54 can be increased. Note that the cylindrical body 54, as viewed from the suction port 10 side at the rear end of the main body case 1, extends all of the driving source within the projection plane of the cylindrical body 54 as long as it partially protrudes outward from the outer portion of the driving source. It is not necessary to enter the part. Since the drive source is not an even shape and has an uneven cross-sectional shape, not all the drive sources are within the projection plane of the cylinder 54.
[0031]
In addition to the above, the ion generator 15 and the ion passage 21 can be provided inside a nozzle 33 that is detachably attached to the air outlet 11, and when the main body case 1 has a left and right split structure, The ion generator 15 and the ion passage 21 can be directly assembled in the case 1. The ion passage 21 can be formed of an elastically deformable tube. The ion generator 15 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-like insulator (dielectric) made of mica, ceramic, or the like, and two needle-like electrodes are opposed to each other. The structure is not limited in any way as long as the structure can be changed to an electrode structure and the like and ions can be generated. The blower according to the present invention includes devices such as a hand dryer and a foot dryer. In addition, a fan without a heater is included in the blower of the present invention.
[0032]
The wind conductor 1 </ b> A can be formed integrally with the main body case 1. In that case, after the rectifying cylinder 17 and the ion generator 15 are assembled to the main body case 1 from the side of the suction port 10, the insulating frame 8, the heater 9, the circuit board 13, and the transformer 14 are attached to the main body case 1. It is good to assemble. When the nozzle 33 is used in combination, a nozzle body 34 having a peripheral surface provided with an opening for taking in outside air may be used. In that case, by the ejector action by the air flow generated by the fan 6, the outside air is introduced into the nozzle 33 from the opening, and the warm air passing through the nozzle 33 is mixed with the outside air containing moisture. As a result, hair damage can be reduced as compared with the case of blowing only warm air. In the embodiment, the case where negative ions are supplied has been described. However, the object to be supplied may be positive ions, and even in this case, the depletion of positive ions during the supply path is well prevented, Can be delivered effectively. When generating positive ions, the diodes in FIG.
[0033]
The wind intake body 51 may be configured separately from the cylindrical body 54 instead of being integrally formed as long as the flow of the wind can be changed toward the wind intake opening 52 and the inlet 40. . In the first embodiment, three plate-like wind intake bodies 51 are formed with an angle of 120 degrees in the circumferential direction of the cylindrical body 54 (see FIG. 6), but six with an angle of 60 degrees in the circumferential direction. It may be formed or provided without having a certain angle. Alternatively, only one may be provided. The wind intake body 51 may have a fine mesh shape.
[0034]
In each of the above embodiments, the transformer 14 is used as a drive source that faces the inlet 40 of the cylindrical body 54. However, the drive source may be the motor 7 that drives the fan 6, or the circuit board 13. Also good. In short, it is an electrical component that is housed in the main body case 1 and obstructs the flow of wind in the main body case 1. However, as in the above-described embodiments, it is convenient to place the transformer 14 and the cylindrical body 54 so as to face each other so that the wiring can be shortened.
