ン６はモータにて回転駆動されるようになっている。2. Description of the Related Art FIG. 5A is a cross-sectional view of a conventional hair dryer on a suction port side. At the end of the wind tunnel 3 on the suction side, a suction port 1 is provided, and the area of the suction opening indicated by reference numeral a of the suction port 1 is lattice-shaped, round hole,
A large number of suction holes 2 having a hexagonal shape or the like are provided. In the drawing, only one suction hole 2 is illustrated, and the other suction holes 2 are omitted. The suction port 1 is fixed to the wind tunnel 3 or the blower cylinder 4, and the outer circumference of the suction port 1 and the blower cylinder 4 are fixed.
A slope 5 is provided over the entire circumference. The slope 5 is provided so that a large amount of air can be easily taken in from the suction port 1 to the blower cylinder 4, and the slope 5 is provided so as to gradually widen from the blower cylinder 4 toward the suction port 1. . A fan 6 for taking in air and generating air is provided inside the blower tube portion 4, and the fan 6 is driven to rotate by a motor.

率も悪化させてしまうという問題があった。Here, when the fan 6 rotates, the flow of air entering from the suction port 1 is indicated by arrows A and B.
become that way. At this time, there is a characteristic that the speed at which the air fan 6 enters the side increases as it goes toward the outer peripheral direction of the fan 6. Therefore, there is a difference in speed between the flow of air indicated by arrow A and the flow of air indicated by arrow B. For this reason, as shown in FIG. 5B, air interference occurs near the slope portion 5 and the fan 6 (a portion indicated by a symbol C indicated by a dashed circle), and abnormal noise occurs, resulting in a high noise value. And there is a problem that the blowing efficiency is also deteriorated.

法でなかった。In order to prevent the generation of the abnormal noise, the fan 6 is avoided from the suction port 1 by a dimension as shown in FIG. 6 or the range of the opening of the suction port 1 is denoted by reference character b as shown in FIG. Methods of reducing the size only by the dimensions shown or eliminating the slope portion 5 as shown in FIG. 8 have been adopted, but each has advantages and disadvantages. That is, if the fan 6 is kept away from the suction port 1 as shown in FIG. 6, the hair dryer has a problem that the overall length of the product becomes long. When the method as shown in FIGS. 7 and 8 is adopted, a large air volume is hardly obtained as a product because the opening area on the suction port 1 side becomes small. The only option was to increase the number of revolutions, and it was not a very efficient method in terms of sound and durability.

きる。According to the above configuration, the arrow A is drawn along the slope 5.
Since the air flowing along the ribs 16 flows along the ribs 16, the flow path becomes longer, and the speed of the flow of the air flowing along the arrow A without flowing along the slope 5 and the speed of the air flowing along the arrow A is shown in FIG. The difference becomes small, and the air flow indicated by the arrow A and the air flow indicated by the arrow B do not interfere with each other. In addition, since the slope 5 is provided, a sufficient air volume can be secured.
Can be made compact because it is not separated from the suction port 1.

構造となっている。A rib 16 is provided on the slope 5 so as to protrude from the blower cylinder 4 toward the suction port 1 in a cylindrical shape over the entire circumference. Although one cylindrical rib 16 is provided in the present embodiment, a plurality of such ribs may be provided. A gap 18 is provided between the cylindrical rib 16 and the suction port 1, and air flows from the suction port 1 through the gap 18 as shown by an arrow A in FIG. It has a structure that flows to the 6 side. At this time, the difference between the air flow speed indicated by the arrow A and the air flow speed indicated by the arrow B becomes small because of the ribs 16. That is, since the flow of the air indicated by the arrow A flows along the ribs 16, the flow path can be made longer, and the difference between the speed of the air flow indicated by the arrow A and the speed of the air flow indicated by the arrow B is reduced. As a result, the flow of the air indicated by the arrow A and the flow of the air indicated by the arrow B do not interfere with each other near the fan 6, and the generation of abnormal noise can be suppressed. Further, since the gap 18 is formed between the suction port 1 and the cylindrical rib 16, it is difficult to reduce the air blowing efficiency, and the suction opening of the suction port 1 can be set to be large according to the slope 5. Because of this, it has a structure that makes it easy to obtain a large air volume.

In the case of the present embodiment, a cylindrical rib 16 is provided so as to protrude so as to divide the slope 5 into a slope 5a and a slope 5b. In this case as well, the flow path of the arrow A can be lengthened by the cylindrical rib 16 as in the above-described embodiment, so that the speed of the air flow can be suppressed. Generation of sound can be suppressed.

のである。As described above, according to the present invention, one or a plurality of cylindrical ribs protruding from the slope along the blowing direction are provided on the slope so as to extend from the periphery of the outer periphery of the suction port. The speed of the incoming air flow can be suppressed by the ribs, so that the interference noise of the air can be suppressed, and the noise value can be kept low. It is possible to provide a compact hair dryer because it is possible to shorten what had to be secured large, and it is possible to set the shape of the suction port larger than the blower cylinder, so that a larger air volume is obtained It is possible to provide a hair dryer that can.
