Description

  The present invention relates to a multi-nozzle for a hair dryer that is attached to a jet opening from which hot air from a hair dryer blows out. More specifically, the present invention relates to a plurality of jets at relatively low temperatures that do not damage the hair with hot air from the hair dryer. The present invention relates to a multi-nozzle for a hair dryer that blows out as wind to dry hair.

  In recent years, interest in hair care has been extended to a wide range of generations, regardless of gender. In general, when the wet hair is naturally dried after shampooing, moisture will adhere to the scalp for a long time, which causes an increase in germs. Therefore, it is said that it is better for the scalp to immediately dry the hair wet with a hair dryer or the like.

  However, when drying wet hair with a hair dryer, if the distance between the hair and the hair dryer is shortened, the warm air from the hair dryer concentrates on a part of the hair and becomes hot, which adversely affects the hair. give. In the case of drying wet hair with a hair dryer, the wet hair is dried while shaking the hair dryer left and right so that warm air from the hair dryer does not concentrate on a part of the hair.

  In addition, the blowout opening from which the hot air of the conventional hair dryer blows has a structure in which the cross-sectional area decreases toward the tip, and the hot air is concentrated on a part of the hair. In addition, spraying only warm air on the hair causes damage to the hair, so in addition to blowing warm air warmed by the heater in the hair dryer, the outside air that has not been warmed by the heater is sucked in, There is also a double-structured hair dryer that blows outside air simultaneously with warm air.

  This double-structure hair dryer can dry wet hair at a lower temperature in which warm air and external air are mixed, compared to a hair dryer that blows out only warm air. However, in the actual measurement result, the temperature when hitting the hair is relatively high, for example, about 110 ° C., and the hot air of this high temperature damages the hair.

  The temperature of hot air from the hair dryer necessary for drying wet hair is generally 60 ° C. to 70 ° C., and the temperature of 80 ° C. or more adversely affects the hair. Accordingly, there is a demand for the development of a hair dryer that can dry wet hair in a short time in a short time so that the temperature of the warm air from the hair dryer is low so as not to damage the hair.

And the said rear-end part of the said double structure type hair dryer 3 comprises the air suction opening part 3b which attracts | sucks the air from the outside as shown by the arrow 101. FIG.

  Further, a cylindrical hot air passage cylindrical portion 11 is provided inside the double structure hair dryer 3 and between the fan 7 and the ejection opening 3a. The double-structured hair dryer 3 is formed of a cylindrical body having an outermost cylindrical shape. The outermost cylindrical tubular body is referred to as an outside air passing tubular portion 13.

  Further, a heater 15 which is a heating means for generating warm air by heating the air from the outside sent from the fan 7 is disposed inside the hot air passage cylindrical portion 11. Further, a heat-resistant net 9 is attached to the ejection opening 3a and the air suction opening 3b so that foreign matter, dust, fingers, etc. do not enter inside the fan 7 and the heater 15.

The handle portion 17 is rotatably attached so as to be close to or away from the longitudinal direction of the outside air passing tubular portion 13 with the base end portion attached to the outside air passing tubular portion 13 as a center. .

  The multi-nozzle 5 of the present embodiment is attached to the ejection opening 3 a that is the tip of the outside air passage tubular portion 13 of the double structure type hair dryer 3. The multi-nozzle 5 has a short cylindrical outer ring cylinder 21 having the same diameter as the outside air passing cylindrical part 13 and a plurality of (this embodiment) disposed inside the outer ring cylindrical body 21. 3) of cylindrical bodies 23a, 23b, and 23c. In addition, when describing several cylindrical body 23a, 23b, 23c generically, it describes as the cylindrical body 23 only.

  The plurality of cylindrical bodies 23 extend in the same direction as the outer ring cylindrical body 21. More specifically, the free end 24 that is the tip of the cylindrical body 23 is longer than the outer ring cylinder 21 and protrudes outward from the tip of the outer ring cylinder 21. Further, each of the plurality of cylindrical bodies 23 has a cylindrical shape with the same inner diameter from the front end to the rear end, and each cylindrical body 23a, 23b, 23c has a central axis in the same direction and parallel to each other. It is arranged to become.

  Further, the outer ring cylinder 21 promotes the lowering of the ejection temperature by the cylinders 23a, 23b, 23c. Specifically, the ratio of the high temperature region of 70 ° C. or higher is the cylinder 23. Compared with the jetting by only the double structure, the double structure including the outer ring cylinder 21 can further reduce the temperature by 10 to 12%.

  FIG. 2 is a cross-sectional view schematically showing a cross section viewed from the side of the hair dryer 1 shown in FIG. 3 (a), (b) and (c) are front views of the multi-nozzle 5 attached to the hair dryer 1 shown in FIG. 1 and FIG. It is sectional drawing seen from side AA, and the perspective view seen from the back side.

  As shown in FIG. 2, the outer ring cylinder 21 of the multi-nozzle 5 has the same diameter as the outside air passage cylindrical portion 13 of the double-structure hair dryer 3, and the outer ring cylinder body 13 extends from the outside air passage cylindrical portion 13. It is continuously connected to and connected to 21. Further, the base end portion 25 opposite to the free end portion 24 of the plurality of cylindrical bodies 23 does not extend to the ejection opening portion 3a of the double structure type hair dryer 3, and is slightly before the ejection opening portion 3a. At the end, a space 31 is provided between the ejection opening 3 a and the base end 25 of the cylindrical body 23.

  In addition, the free end part 24 and the base end part 25 of several cylindrical body 23a, 23b, 23c exist for each cylindrical body 23a, 23b, 23c, respectively, and free end part 24a, 24b, 24c and the base end portions 25a, 25b, and 25c, but the subscripts a, b, and c are omitted here for the sake of simplification, like the free end portion 24 and the base end portion 25. It is described generically.

  As described above, a space 31 is provided between the base end portion 25 of each tubular body 23 and the ejection opening 3a, and the bases of the plurality of tubular bodies 23 that are terminated slightly before the ejection opening 3a. A gap 33 exists between the end portions 25 as shown in FIG. 3A when the plurality of cylindrical bodies 23 are viewed from the front. If such a gap 33 exists, all the hot air from the ejection openings 3a does not enter the plurality of cylindrical bodies 23, and the hot air leaks from the gap 33. The gap 33 between the base end portions 25 of the plurality of cylindrical bodies 23 is formed so as to prevent leakage from the 33 and distribute the warm air from the ejection openings 3a evenly and smoothly to the plurality of cylindrical bodies 23. The gap closing portion 27 is closed as shown in FIGS.

  Further, as shown in FIG. 2 and FIG. 3 (b), the outermost peripheral portion of the gap closing portion 27 is ejected so as to prevent leakage of the warm air from the outermost peripheral portion. It extends so as to rise toward the opening 3a to reach the ejection opening 3a, thereby closing the space between the outermost peripheral edge and the ejection opening 3a, and the air volume that is the space together with the gap closing part 27 A peripheral blockage wall 29 constituting the adjustment unit 31 is provided.

  That is, the air volume adjusting unit 31 is the space surrounded by the gap blocking portion 27, the peripheral blockage wall 29, and the ejection opening 3a, and in this space, the hot air passage cylinder of the double structure type hair dryer 3 is provided. The hot air from the tubular portion 11 is stored and buffered, whereby the warm air from the warm air passing tubular portion 11 is evenly distributed and evenly distributed to each of the plurality of tubular bodies 23. However, the warm air is sent to the outside as a plurality of blown air from the free end portions 24 of the plurality of cylindrical bodies 23, specifically toward the wet hair at a relatively low temperature. There is no concentration of heat, and a large amount of blown air is blown out in a diffused state, and is dried in a short time while loosening without damaging wet hair. Further, as described above, the outer ring cylinder 21 is formed by projecting the plurality of cylinders 23 from the outer ring cylinder 21, that is, by forming the outer ring cylinder 21 shorter than the cylinder 23. The diffusion of the external air ejected from the hot air and the warm air ejected from the tubular body 23 is promoted, the temperature of the hot air hitting the hair can be lowered and the proportion of the high temperature region is also reduced. In addition, when the length of the cylindrical body 23 that ejects warm air is 35 mm and the length of the outer ring cylinder 21 that ejects external air is 10 mm, the temperature can be lowered most, but experimentally. Has been obtained. Further, when the inner area surrounded by the peripheral wall 29 is A, and the total area obtained by adding the areas of the ends of the openings of the plurality of cylindrical bodies 23 is a, the relationship between them is as follows: Preferably it is.

2/3 × A = a
However, the coefficient 2/3 only needs to be within a range of 2/5 to 4/5. When the coefficient is 2/5 or more, the effect of the air volume adjusting unit 31 described above and the air volume from each cylindrical body 23 are uniform. If the effect is less than 4/5, the air resistance increases and the efficiency decreases, which is not preferable.

  In order to dry the wet hair using the hair dryer 1 attached to the jet opening 3a of the double-structure hair dryer 3, the multi-nozzle 5 configured as described above is the tip of the hair dryer 1. When the free ends 24 of the cylindrical bodies 23 of the multi-nozzle 5 are separated from the wet hair by, for example, 150 mm to 200 mm and a power switch (not shown) is turned on, electric power is supplied to the heater 15 and the heater 15 is driven. The fan 7 is driven and rotated, and the fan 7 sucks external air from the air suction opening 3b as shown by an arrow 101, and the sucked air is shown by an arrow 103 in FIG. In addition to being sent into the hot air passage cylindrical portion 11, it is also sent into the outside air passage cylindrical portion 13 outside the hot air passage cylindrical portion 11 as indicated by an arrow 104.

  The external air sent into the hot air passage cylindrical portion 11 by the fan 7 is warmed by the heater 15, and as a hot air, as indicated by an arrow 105, a multi-nozzle is formed from the ejection opening 3 a of the hot air passage cylindrical portion 11. 5 is sent into the air volume adjusting unit 31. As described above, the warm air sent into the air volume adjusting unit 31 is uniformly dispersed in the air volume adjusting unit 31 and is uniformly distributed to each of the plurality of cylindrical bodies 23. The air is sent to each of the bodies 23 and is blown out from each free end 24 of the plurality of tubular bodies 23 toward the wet hair as a plurality of blown air, and at the same time, the outside air of the double-structure hair dryer 3 The external air sent into the passage cylindrical portion 13 is not heated by the heater 15, and as shown by an arrow 106, the outer ring cylinder of the multi-nozzle 5 from the ejection opening 3 a of the double-structure hair dryer 3. 21 and the peripheral closed wall 29 and between the outer ring cylinder 21 and the outer walls of the plurality of cylindrical bodies 23, and are ejected to the outside around the free ends 24 of the plurality of cylindrical bodies 23. A plurality of cylindrical bodies 23 While being mixed with hot air blown out as a blown-out air, the temperature is lowered and the air is blown out in a diffused state with a high speed at a relatively low temperature and without rapid heat concentration. It can be efficiently blown out in a short time while loosening without damaging wet hair.

  FIG. 4 is a diagram showing the temperature distribution and velocity distribution of hot air when the hair is dried using the hair dryer 1 of the present embodiment described above. Hereinafter, in FIGS. 4, 5, and 8, the temperature distribution is a capital letter and indicates a region where the temperature is low from A to D, and the velocity distribution is a small letter and the region where the wind speed is slow from a to d. That is, the region A has the highest temperature, and the region a has the highest wind speed.

  5 shows the comparison of the temperature distribution and the velocity distribution of the warm air of the hair dryer 1 of the present embodiment shown in FIG. 4 in the conventional simple double-structure hair dryer. It is a figure which shows temperature distribution and speed distribution. The temperature distribution and velocity distribution of the hot air shown in FIGS. 4 and 5 show the temperature distribution and velocity distribution of the hot air in the collision plate provided with a collision plate instead of the hair.

  4 and 5, the distance L between the free ends 24 of the three cylindrical bodies 23 that are the hot air jets from the hair dryer 1 and the collision plate is L = 100 mm, L = 150 mm. And the temperature distribution and speed distribution of the warm air when L = 200 mm are shown.

  As can be seen from FIG. 4, in the hair dryer 1 of the present embodiment, the center of the collision plate is the highest temperature and the wind speed is slow in any of the distances L = 100 mm, L = 150 mm, and L = 200 mm. At the same time, the high temperature region is narrowed and the appropriate temperature region is expanded. Further, a stagnation region is formed at the center of the collision plate where the blown air from each cylindrical body 23 gathers. By forming this stagnation region, the jet velocity of the hot air jetted from the cylindrical body 23 of the multi-nozzle 5 is attenuated, and the turbulence of the jet wind is generated directly below the cylindrical body 23, and the center of the collision plate Temperature rises. Moreover, although the wind speed is faster than before, the range where the wind speed is slow is narrow.

  Furthermore, under any of the conditions of distance L = 100 mm, L = 150 mm, and L = 200 mm, the temperature between the two adjacent cylindrical bodies 23 becomes high as shown by an ellipse surrounded by a dotted line, The wind speed is getting faster. This is because, as shown by the oval dotted line in FIG. 4, the blown-out winds collide with each other, and the wind speed between the cylindrical bodies 23 increases. As described above, since the wind speed between the cylindrical bodies 23 increases, it is possible to disperse the partial concentration of the warm air. Further, under any of the conditions of distance L = 100 mm, L = 150 mm, and L = 200 mm, the temperature at the highest temperature does not become 70 ° C. or lower, and a plurality of cylindrical bodies 23 as in this embodiment. However, the temperature decreases, but the high temperature region is as large as 80%. Note that when the distance L = 200 mm, the cylindrical body 23 is less susceptible to the influence.

  On the other hand, as shown in FIG. 5, in the conventional hair dryer, the center of the collision plate becomes the highest temperature and the wind speed becomes slow at any distance L = 100 mm, L = 150 mm, and L = 200 mm. In the case of L = 100 m and L = 150 mm, there is almost no change in the center temperature of the collision plate. However, at the distance L = 200 mm, the hot air blown out and the outside air diffuse to cause the center temperature of the collision plate. Is lower than the distance L = 100 mm and L = 150 mm. However, under any of the conditions of distance L = 100 mm, L = 150 mm, and L = 200 mm, the temperature at the highest temperature is 60 ° C. to 70 ° C. or more, and the temperature distribution is not uniform. Further, the ratio of the high temperature region of 70 ° C. or more is as high as about 40% when the distance L = 100 mm, about 80% when L = 150 mm, and about 70% when L = 200 mm. Further, when the distance from the cylindrical body 23 to the collision plate is increased, the temperature decreases.

  FIG. 6 is a perspective view showing a hair dryer to which a multi-nozzle according to another embodiment of the present invention is attached. The hair dryer 100 shown in the figure is similar to FIG. 1 in which the multi-nozzle 50 of this embodiment is attached to the ejection opening 3a at the tip of the double-structure hair dryer 3, and this double-structure hair The structure of the dryer 3 is the same as that shown in FIG.

  Moreover, the multi-nozzle 50 of this embodiment attached to the ejection opening part 3a of this double structure type hair dryer 3 has the multi-nozzle 5 of the embodiment shown in FIG. In contrast, the only difference is that the four cylindrical bodies 23a, 23b, 23c, and 23d are provided, and the other configurations and operations are the same as those of the embodiment shown in FIG. Therefore, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIGS. 7A, 7B and 7C are front views of the multi-nozzle 50 attached to the hair dryer 100 shown in FIG. 6 as viewed from the side of the plurality of cylindrical bodies 23a, 23b, 23c and 23d. They are sectional drawing seen from the side, and the perspective view seen from the back side. Also in this figure, the multi-nozzle 50 is different only in that it includes four cylindrical bodies 23a, 23b, 23c, and 23d, and other configurations and functions are the same as those of the embodiment shown in FIG. Therefore, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 8 is a diagram showing the temperature distribution and velocity distribution of hot air when the hair is dried using the hair dryer 100 of the embodiment shown in FIG. The temperature distribution and velocity distribution of the hot air shown in FIG. 8 also show the temperature distribution and velocity distribution of the hot air in the collision plate provided in place of the hair, as in FIG. Also in FIG. 8, the distance L between the free ends 24 of the four cylindrical bodies 23a, 23b, 23c, 23d, which are hot air outlets from the hair dryer 100, and the collision plate is L = 100 mm, The temperature distribution and velocity distribution of the hot air when L = 150 mm and L = 200 mm are shown.

  As can be seen from FIG. 8, even in the hair dryer 100 to which the multi-nozzle 50 using the four cylindrical bodies 23 is attached, the distances L = 100 mm, L = 150 mm and In any case of L = 200 mm, the center of the collision plate becomes the highest temperature. A stagnation region is formed at the center where each cylindrical body 23 gathers, and by forming this stagnation region, the speed of the blown air is attenuated, and the turbulence of the blown air is generated directly below the tubular body 23, The center temperature is high. Furthermore, in any case, the temperature between the two adjacent cylindrical bodies 23 increases. This is because the blown air collides with each other and the wind speed between the cylindrical bodies 23 increases as shown by the oval dotted line in FIG. As described above, since the wind speed between the cylindrical bodies 23 increases, it is possible to disperse the partial concentration of the warm air. Under any of the conditions, the temperature at the highest point does not become 70 ° C. or lower, and the temperature decreases by providing a plurality of cylindrical bodies 23 as in the present embodiment. Is as large as 80%. Note that when the distance L = 200 mm, the cylindrical body 23 is less susceptible to the influence.

  By setting the number of the cylindrical bodies 23 of the multi-nozzle 50 to four as in the present embodiment, the temperature on the collision plate can be lowered by about 10 ° C. compared to the prior art, and 70 The proportion of high temperature regions above ° C has also decreased.

  FIG. 9 is a perspective view showing a hair dryer to which a multi-nozzle according to another embodiment of the present invention is attached.

  Moreover, the multi-nozzle 500 of this embodiment attached to the ejection opening part 3a of this double structure type hair dryer 3 is provided with three cylindrical bodies 23 in the multi-nozzle 5 of the embodiment shown in FIG. On the other hand, the only difference is that the five cylindrical bodies 23a, 23b, 23c, 23d, and 23e are provided. Other configurations and operations are the same as those of the embodiment shown in FIG. Therefore, the same components are denoted by the same reference numerals, and description thereof is omitted.

  10A, 10B, and 10C are viewed from the side of the plurality of cylindrical bodies 23a, 23b, 23c, 23d, and 23e of the multi-nozzle 500 attached to the hair dryer 200 shown in FIG. It is the front view, sectional drawing seen from the side, and the perspective view seen from the back side. Also in this figure, the multi-nozzle 500 is different only in that it includes five cylindrical bodies 23a, 23b, 23c, 23d, and 23e, and other configurations and functions are shown in FIG. Since it is the same as that of the embodiment, the same components are denoted by the same reference numerals and description thereof is omitted.

  In addition, in the multi-nozzle 500 of the hair dryer 200 shown in FIGS. 9 and 10, the five cylindrical bodies 23a, 23b, 23c, 23d, and 23e are annularly arranged. The arrangement of the plurality of cylindrical bodies 23 is not limited to this. For example, the five cylindrical bodies 23a, 23b, 23c, 23d, and 23e are formed as a single cylindrical shape as shown in FIG. The four cylindrical bodies 23a, 23b, 23c, and 23d may be arranged in an annular shape so as to surround the periphery around the body 23e. In this case, by making the inner diameter of the central cylindrical body 23e slightly thicker than the inner diameters of the other cylindrical bodies 23a, 23b, 23c, and 23d, the air volume and temperature when hitting the hair are further increased. It becomes possible to make uniform, and a more preferable result is obtained.

  Moreover, although the number of the cylindrical bodies 23 demonstrated the case where the number of the cylindrical bodies 23 was three, four, and five in the several embodiment mentioned above, this invention is not limited to this, Two or six It may be more than a book. In this case, the arrangement of the cylindrical bodies 23 may be doubled, for example, 6 cylindrical bodies 23 on the outside and 3 cylindrical bodies 23 on the inside.

  Further, in the above-described embodiments, the case where the multi-nozzles 5, 50, 500 are attached to the double-structured hair dryer 3 as a hair dryer has been described, but the present invention is not limited to this. It can also be applied to hair dryers that are not heavy.

  The present invention has been described with reference to a plurality of embodiments. However, each embodiment is an exemplification, and the scope of the invention described in the claims can be variously modified without departing from the scope of the invention. It is.
