Blow area and wind speed can be adjusted. Specifically, when the airflow adjustment structure is adjusted so that the connection height of the direction-changing nozzle 20 with respect to the nozzle base 19 is at a low position, the opening area of the nozzle outlet 24 is reduced and air is supplied from the direction-changing nozzle 20 . It is possible to limit the supply area of the dry air to a narrow area, increase the air velocity, and allow the dry air to reach a longer distance. Conversely, if the airflow adjustment structure is adjusted so that the connection height of the direction-changing nozzle 20 with respect to the nozzle base 19 is at a high position, the opening area of the nozzle outlet 24 is increased, and the air is supplied from the nozzle outlet 24 . It is possible to expand the delivery area of the dry air to a wide area, reduce the air velocity to reduce the reaching distance of the dry air, and gently supply the dry air to the hair. Therefore, according to the dryer of Example 1, it is possible to dry the hair in various forms according to the condition of the hair and scalp, or the difference in the amount of hair.

The direction-changing nozzle 20 is configured in a multi-walled manner by a nozzle inner wall 22 and a nozzle outer wall 23 covering the periphery of the outer surface of the nozzle inner wall 22 . With such a direction-changing nozzle 20, it is inevitable that the temperature of the inner wall 22 of the nozzle rises when drying hair continuously while blowing hot air. However, since the periphery of the nozzle inner wall 22 is covered with the nozzle outer wall 23 and the upper part of the nozzle inner wall 22 is covered with the base cover 21, the user's finger accidentally touches the hot nozzle inner wall 22 and feels uncomfortable. can be reliably prevented. In addition, since a gap is interposed between the base cover 21 and the nozzle outer wall 23 and the nozzle inner wall 22, the heat insulation effect of the air existing in the gap prevents the conduction of radiant heat from the nozzle inner wall 22 as much as possible. And the nozzle outer wall 23 can be well prevented from overheating.

In the air blowing adjustment structure of the dryer of the sixth embodiment, the direction-changing nozzle 20 is oscillated back and forth with respect to the nozzle base 19 to adjust the opening area of the nozzle outlet 24, and the dry air supplied from the nozzle outlet 24 is adjusted. , and the wind speed can be changed. More specifically, the nozzle base 19 is provided with an elbow-shaped direction-changing wall 19a, and the lower ends of the left and right walls 20c of the direction-changing nozzle 20 are supported by a pair of support shafts 77 so as to be able to swing back and forth. 27 and a movable opening 28 on the side of the direction-changing nozzle 20 constitute a nozzle outlet 24. - 特許庁The direction-changing nozzle 20 includes a curved wall 20a that reciprocates and slides along the outer surface of the direction-changing wall 19a of the nozzle base 19, a straight wall 20b that continues to the front end of the curved wall 20a, and left and right walls supported by a support shaft 77. 20c is integrally provided, and the upper surfaces of the curved wall 20a and the straight wall 20b are covered with a cover body 20d. Non-slip ribs 20e are formed on both left and right sides of the cover body 20d.

According to the airflow adjustment structure described above, the opening area of the nozzle outlet 24 can be adjusted to a larger or smaller size by applying fingertips to the right and left non-slip ribs 20e and swinging the direction-changing nozzle 20 back and forth. . When the direction-changing nozzle 20 is closest to the solid opening 27 on the nozzle base 19 side, as shown by the solid line in FIG. It is possible to limit the dry air supply area to a narrow area, increase the wind speed, and allow the dry air to reach a longer distance. Conversely, when the direction-changing nozzle 20 is tilted backward as indicated by the imaginary line in FIG. It is possible to spread the air over a wide area, reduce the air velocity, reduce the reaching distance of the dry air, and gently supply the dry air to the hair.

Conversely, when the air blow adjustment structure is adjusted so as to increase the opening area of the nozzle outlet 24, the supply area of the dry air supplied from the direction-changing nozzle 20 is expanded to a wide area, and the air velocity is increased. By lowering it, the reaching distance of the drying air can be reduced, and the drying air can be gently supplied to the hair. Therefore, it is possible to provide a dryer capable of drying with various blowing modes according to the user's preference, the difference in the part to be dried, and the like.

The direction-changing nozzle 20 is composed of a nozzle inner wall 22 for changing and guiding the direction of the dry air supplied from the outlet 14 and at least one nozzle outer wall 23 covering the outer surface of the nozzle inner wall 22 so as to form a multi-walled structure. made it According to such a dryer, even if the temperature of the nozzle inner wall 22 rises when the hair is dried continuously while blowing hot air, the periphery of the nozzle inner wall 22 is covered with the nozzle outer wall 23. Therefore, it is possible to prevent the finger from accidentally touching the hot nozzle inner wall 22 and causing discomfort to the user.

A fixed opening 27 formed in the nozzle base 19 and a movable opening 28 formed in the direction-changing nozzle 20 constitute a nozzle outlet 24, and the posture of the direction-changing nozzle 20 is adjusted by the air blow adjustment structure to open the nozzle outlet.
