Description

  The present invention relates to a hair dryer, and more particularly to a structure of a discharge nozzle attached to the tip of an outlet of a hair dryer, and more particularly to a hair dryer that can obtain a rectifying effect when the hair is dried and blown.

  Conventionally, discharge nozzles for hair dryers have been provided with a nozzle that has been squeezed to increase the wind speed in order to dry the hair quickly, or a nozzle that has a double structure to change the opening area within the nozzle. However, simply squeezing the tip of the nozzle increases the momentum of the wind, but a resistance to the flow of the wind causes discharge of the scattered wind, which makes it impossible to discharge efficiently. Moreover, even if the opening area in the nozzle is changed, for example, the nozzle has a double structure, wind interference occurs in the nozzle as well, causing a loss in the wind flow and weakening the wind speed.

  Then, there exists a hair dryer as described in the following patent document 1 (patent 3598928 gazette) as a thing which increases a wind speed and improves the energy efficiency of a wind. As shown in FIG. 5, the nozzle 58 of the air outlet 51 is used in a hair dryer having a fan 54, a motor 55, a rectifying blade 56 and a heater 57 inside a housing 53 having an air outlet 51 and an inlet 52. Is composed of an inner nozzle 60 and an outer nozzle 59, and the inner nozzle 60 is inclined with respect to the nozzle central axis X from the upstream side toward the downstream side, and the cross-section nozzle central axis X is located downstream of the inclined portion 60e. The parallel part 60f formed substantially in parallel was formed.

Furthermore, there exists a hair dryer as described in the following patent document 2 (Unexamined-Japanese-Patent No. 2006-75194) which suppresses attenuation | damping of a wind speed and gives a rectification effect. As shown in FIG. 6, the discharge nozzle 16 is provided at the tip of the hair dryer main body 11, and the rectifying blades 16 a are provided inside the discharge nozzle to rectify the wind that has passed through the hot air generation chamber 17. 16 rectifying blades 16 a are arranged in the same direction as the wind blowing direction, and have a shape that twists the wind from the hot air generating chamber 17, and the rectifying blades 16 a The fan 20a was formed in a shape giving a twist in the direction opposite to the rotation axis direction.
Japanese Patent No. 3598928 (paragraphs [0005] to [0007], FIG. 1) JP 2006-75194 A (paragraphs [0028] to [0029], FIG. 1)

  However, in the nozzle of the above-mentioned patent document 1, by providing the inner nozzle, the momentum of the wind blown from the inner nozzle is increased, but since it is configured in a flat plate shape, it is sufficient to arrange the blown wind. Rectification effect cannot be obtained. Moreover, in the nozzle of the said patent document 2, although the outer wind is rectified among the winds discharged from a nozzle by providing the rectifying blade, the inner wind is not affected by the rectifying blade. There was a drawback that the rectifying effect could not be obtained.

  An object of the present invention is to solve the above-described problem, and an object of the present invention is to provide a discharge nozzle of a hair dryer that can reduce the wind speed and obtain a rectifying effect.

  In order to achieve the above object, a hair dryer according to claim 1 has a suction port, and includes a heater, a fan, and a discharge nozzle attached to a blower outlet of a hair dryer incorporating a motor for driving the fan. A partition wall that divides the air discharge passage into a plurality of front and rear directions is provided inside the discharge nozzle. The partition wall includes at least a pair of partition walls that are curved toward the inside of the air discharge passage, and is partitioned by the partition wall. The opening area is characterized in that the area partitioned between the plurality of partition walls is larger than the area partitioned by the nozzle outer wall and one partition wall.

  A hair dryer according to a second aspect is the hair dryer according to the first aspect, wherein a negative ion discharge port is provided at the air outlet, and the negative ion discharge port is disposed close to the partition wall.

  A hair dryer according to claim 3 is the hair dryer according to claim 1, wherein a rectifying blade is provided on the partition wall.

  A hair dryer according to claim 4 is the hair dryer according to claim 1, wherein a plurality of rectifying blades are provided to form an air enclosing portion.

  The hair dryer according to claim 5 is the hair dryer according to claim 1, wherein an air outlet is provided inside the discharge nozzle, and the air outlet connects the large-diameter curved wall and the curved walls to each other. It is characterized in that a recessed portion recessed inside is provided.

  A hair dryer according to a sixth aspect is the hair dryer according to the first aspect, wherein an air outlet is provided inside the discharge nozzle, and the air outlet connects the large-diameter curved wall and the curved walls to each other. A plurality of small-diameter curved walls that curve outward are substantially elliptical, and partition walls are connected between the large-diameter curved walls.

That is, according to the invention of claim 1, the discharge nozzle is provided at the outlet of the wind discharged from the hair dryer, and the partition wall that curves toward the inside of the discharge nozzle is provided, so that the outlet is changed from the outlet to the discharge nozzle. It is possible to cause a change in airflow in the inflowing wind, rectify the wind discharged from the discharge nozzle, and hit the desired portion of the hair. In particular, since the partition wall is curved inward, the amount of the blown wind comes into contact with the partition wall increases, so that the rectifying effect is improved.

  Further, since the wind blown from the discharge nozzle has a strong central wind and a relatively weak wind, the opening area of the discharge nozzle partitioned by the partition wall is one partition. By increasing the area divided between the plurality of partition walls and the inner wall of the discharge nozzle, or between the plurality of partition walls, rather than the area divided by the wall and the inner wall of the discharge nozzle, the center of the discharge nozzle remains strong. Since the volume of air can be discharged, and the surrounding wind is rectified and discharged by the partition wall, the wind blown from the center is wrapped by the rectified air around it. The wind can be applied to the hair more effectively without breaking.

  According to the invention of claim 2, by arranging the negative ion discharge port along the curve of the partition wall, the negative ion discharged from the negative ion discharge port collides with the air flow changed by the partition wall, and is rectified and discharged. The entire wind discharged from the nozzle can be mixed.

  According to the invention of claim 3, by providing the rectifying blades on the partition wall, the airflow mixed with the negative ions is rectified and discharged by the partition wall.

  According to the fourth aspect of the present invention, the plurality of rectifying blades of the partition wall form a plurality of air enclosing portions, so that air currents mixed with negative ions are trapped by the partition wall and discharged.

  According to the invention of claim 5, by providing the concave portion recessed on the side of the air discharge passage on the small-diameter curved wall, the cool air outside the discharge nozzle is attracted to obtain an appropriate air temperature, and the wind gentle to the scalp is discharged. can do.

  According to the sixth aspect of the present invention, by making the air outlet inside the discharge nozzle into a substantially elliptical shape, the wind to be blown out can be narrowed and a strong wind is discharged, and the partition is formed between the large-diameter curved walls. By connecting the walls, the wind near the center of the discharge nozzle can be further rectified.
