In all the drawings for explaining the embodiments, members having the same function are denoted by the same reference numerals, and repeated description thereof may be omitted.

  As shown in FIGS. 1 and 2, the hair dryer 1 according to the present embodiment has a grip 12 foldably attached to a lower portion of the housing 11, and a suction port 14 for taking in air (outside air) is provided in the rear portion of the housing 11. In addition, a delivery port 16 for delivering the taken-in air is provided at the front portion of the housing 11. Thus, a cylindrical ventilation path 15 through which the air flows is formed in the housing 11.

  Here, the delivery port 16 is provided with a nozzle 20. That is, the air delivered from the delivery port 16 passes through the nozzle 20 and is delivered from the tip of the nozzle 20 to reach the user's hair. As an example, the nozzle 20 has a cylindrical shape as shown in FIGS. 2 and 3 and is detachable from the delivery port 16. However, it is not limited to this shape. Moreover, it is good also as a structure fixed to the delivery port 16 so that attachment or detachment is impossible, or the structure formed integrally with a main body. The nozzle 20 provides an effect of controlling the flow of air sent out as will be described later.

  Inside the ventilation path 15 of the housing 11, air flows so that outside air is taken into the ventilation path 15 from the inlet 14 and blown toward the outlet 16, and is sent from the nozzle 20 as warm air (or cold air). Are provided, and a motor 19 that rotationally drives the fan 18 is provided. The rotation speed of the motor 19 is set so as to be switchable between a high speed and a low speed, for example, by switching a switch 13 provided on the grip 12.

  Further, in the ventilation path 15 of the housing 11, the air taken into the ventilation path 15 is heated downstream from the fan 18 (that is, downstream in the flow direction of air generated by driving the fan 18). A heater (not shown) is provided. As an example, the heater is configured by using a heating wire, which makes it possible to generate hot air. In addition, you may provide the cold wind mode which sends out the wind with the temperature of the taken in external air by not energizing a heater.

  In addition, it is good also as a structure which provides the well-known ion generation means (not shown) which generate | occur | produces a negative ion inside the ventilation path 15. FIG.

  Here, the configuration of the nozzle 20 that is characteristic of the present embodiment will be described in detail. As shown in FIGS. 2 and 3, a pair of air collecting plates 21 and 22 are provided inside the nozzle 20 disposed at the outlet 16. The air collecting plates 21 and 22 are each formed in a semi-cylindrical shape, and are arranged so as to face each other in a vertically symmetrical manner so as to form a cylindrical shape (substantially cylindrical shape or substantially conical shape). That is, the pair of air collecting plates 21 and 22 constitutes a cylindrical (substantially cylindrical or substantially conical) ventilation path 17. In FIG. 3B, the planar shape of the air collecting plate 21 is also shown.

  As an example, the nozzle 20 is formed using a resin material such as polycarbonate having heat resistance. However, it is not limited to this material.

  Each of the air collecting plates 21 and 22 has a pair of rotating shaft portions 23 and 24 that protrude in opposite directions on the rotating axes s1 and s2. The pair of rotating shaft portions 23 and 24 are fitted into fitting holes 25 and 26 provided in the inner surface of the main body 20A of the nozzle 20 so that the air collecting plates 21 and 22 can be rotated by the main body 20A. It is supported.

  Here, the rotating operation of the air collecting plates 21 and 22 will be described with reference to FIG. As described above, the air collecting plates 21 and 22 are pivotally supported on the main body 20A by the pair of rotating shaft portions 23 and 24 provided at the rear end portion (rear end portion). Therefore, the front end portions (front end portions) 21A and 22A of the air collecting plates 21 and 22 approach and separate from each other so that the opening area decreases or increases, that is, before and after the ventilation path 17 in the nozzle. It rotates so that the area of the cross section perpendicular to the direction decreases and increases.

  FIG. 4A shows a state in which the front end portion 21A of the air collecting plate 21 and the front end portion 22A of the air collecting plate 22 are close to each other, and the opening area of the ventilation path 17 at the front end portion is minimized. . On the other hand, FIG. 4B shows a state where the front end portion 21A of the air collecting plate 21 and the front end portion 22A of the air collecting plate 22 are separated from each other, and the opening area of the ventilation path 17 at the front end portion is maximized. ing.

  The following operations and effects can be obtained by rotating the air collecting plates 21 and 22 described above. First, if the opening area of the ventilation path 17 in the front end portions 21A and 22A of the air collecting plates 21 and 22 is reduced, the ventilation path 17 is relatively narrowed (a shape that is relatively close to a cone). The flow rate of the air to be sent out increases, and the range of hitting the user's hair becomes narrow, so that the air blowing point can be narrowed down. Therefore, it is possible to send air (wind) suitable for the hair set. On the other hand, if the opening area of the ventilation path 17 in the front end portions 21A and 22A of the respective air collecting plates 21 and 22 is increased, the ventilation path 17 is in a relatively widened state (a shape that is relatively close to a cylinder). The flow rate of the delivered air is reduced, and the range of contact with the user's hair is widened so that the dry area can be increased. Therefore, it is possible to send air (wind) suitable for drying (rapid drying) of hair.

  The rotating operation of the air collecting plates 21 and 22 may be configured to select only two positions shown in FIGS. 4A and 4B (two-stage adjustment structure), or FIG. It is good also as a structure (a multistage adjustment structure or a stepless adjustment structure) which can also select the position between the two positions of (a) and FIG.4 (b). It should be noted that the more the positions selected by the rotating operation of the air collecting plates 21 and 22, the more various adjustments from the air collecting to the opening are possible.

  As described above, according to the configuration according to the present embodiment, the air volume, the wind speed, and the wind pressure of the sent air can be controlled stepwise according to the approach / separation position (that is, the air collecting angle) of the air collecting plates 21 and 22. It becomes possible.

  Next, a configuration for performing the rotation operation of the air collecting plates 21 and 22 will be described. As shown in FIGS. 3 and 4, each of the air collecting plates 21 and 22 is provided with a protruding portion 27 for rotating. Each protrusion 27 has a tip 27A in an arc (here, s1, s2) inside a through hole 28 (for example, a long hole long in the front-rear direction) formed so as to penetrate the main body 20A of the nozzle 20 in the radial direction. Is arranged so as to be movable so as to draw an arc having a central axis of.

  That is, by moving the protrusion 27 toward the front side of the nozzle 20, the action of rotating the air collecting plates 21 and 22 so as to be in the state shown in FIG. On the other hand, by moving the protrusion 27 toward the rear side of the nozzle 20, an action of rotating the air collecting plates 21 and 22 so as to be in the state shown in FIG. 4B is obtained.

  Here, in the present embodiment, an operation ring 30 for moving each projection 27 in the front-rear direction of the nozzle 20 is provided.

  As an example, the operation ring 30 is externally fitted to the nozzle (here, the main body 20A) so as to be slidable in the front-rear direction of the nozzle 20 (see FIGS. 3 and 4). Furthermore, the operation ring 30 has a protrusion engaging hole 32 with which the protrusion 27 is engaged on the inner surface. According to this, when the operation ring 30 is moved toward the front side of the nozzle 20, an action is obtained in which the protrusion 27 is moved toward the front side by being pushed by the rear wall 32 </ b> B of the protrusion engagement hole 32. Further, when the operation ring 30 is moved toward the rear side of the nozzle 20, an action is obtained in which the protrusion 27 is moved toward the rear side by being pushed by the front wall 32 </ b> A of the protrusion engagement hole 32.

  On the other hand, a modification of the operation ring 30 is shown in FIG. More specifically, the nozzle 20 (here, the main body 20A) is provided so as to be rotationally movable in the circumferential direction of the nozzle 20, and the protrusion 27 is engaged with the inner surface to slide. It is good also as a structure which has the helical protrusion engaging groove 34 to be made. According to this, when the operation ring 30 is rotationally moved in a predetermined direction, there is obtained an effect that the protrusion 27 is guided toward the front side by being guided by the spiral protrusion engaging groove 34. Further, when the operation ring 30 is rotated in the other direction, an effect is obtained in which the protrusion 27 is guided toward the spiral protrusion engaging groove 34 and moved toward the rear side.

  Next, the shape of each of the air collecting plates 21 and 22 will be described. As shown in FIGS. 3 and 4, the air collecting plates 21 and 22 have tip portions (front end portions) 21 </ b> A and 22 </ b> A formed in a waveform. According to this, particularly when the tip portions 21A and 22A are brought close to each other, it is possible to make the air (wind) sent from the tip of the nozzle 20 through the ventilation path 17 "random wind". Become. Therefore, compared with the “straight wind”, the air blowing range is widened, and the hair setting time (drying time) can be shortened.

  Further, the air collecting plate 21 and the air collecting plate 22 are formed in the same shape and are arranged symmetrically in the vertical direction. Therefore, the number of parts can be reduced, and consequently the manufacturing cost can be reduced.

  On the other hand, a modification of the shape of each of the air collecting plates 21 and 22 is shown in FIG. More specifically, each of the air collecting plates 21 and 22 is formed in a straight line shape (straight shape) in plan view in which the front end portions (front end portions) 21A and 22A are not wavy. In FIG. 6, the planar shape of the air collecting plate 21 is also shown. According to this, especially when the tip portions 21A and 22A are brought close to each other, it is possible to make the air (wind) sent from the tip of the nozzle 20 through the ventilation path 17 "straight wind". Become. Therefore, it is possible to perform simple air blowing without fluctuation as compared with “random wind”.

  As described above, according to the hair dryer according to the present invention, it is possible to collect and release (spread) the air sent from the nozzle by a simple mechanism. Therefore, it is possible to further enhance the effects of hair setting and drying (quick drying).

  In particular, the tip portions of the air collecting plates can be moved closer to and away from each other simply by sliding the operation ring back and forth. Therefore, it is possible to switch the air (wind) sent from the nozzle tip portion between the air collection and the opening (diffusion). That is, it is possible to control the air volume, the wind speed, and the wind pressure of the sent air by the approach / separation position (wind collecting angle) of each wind collecting plate.

  Further, the nozzle is composed of a very small number of parts such as a main body, a set of air collecting plates having the same shape, and a ring portion, thereby enabling simplification of the structure and reduction of parts cost and assembly cost.

  In this way, since the collection and release (diffusion) of the delivery air can be switched by a simple operation with one nozzle, the hair is set by the air collection and the hair is dried (rapid drying) by the open air (diffusion). ) Can be arbitrarily selected according to the user's preference, and it is possible to effectively obtain a delivery air suitable for each of hair setting and drying (fast drying).

  The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the present invention.

  For example, the operation ring is not limited to the configuration in which the operation ring is slid in the front-rear direction, and may be configured to rotate in the circumferential direction.

  Further, the adjustment of the approach / separation position of each air collecting plate, that is, the adjustment of the air collecting angle is not limited to the two-stage adjustment configuration, but may be a multi-stage adjustment, a stepless adjustment configuration, or the like.

  Moreover, the shape of the front-end | tip part of each wind collecting plate is not limited to a waveform structure, It is good also as a straight-shaped structure.
