A hot air guide path 38 communicating with the hot air passage 28 is formed on the inner periphery of the small diameter portion of the brush stand 31 .
The hot air from the brush stand 31 is blown out through a large number of hot air blow-off/reception ports 39 formed in the small diameter portion of the brush stand 31 and a large number of hot air blow-off ports 40 formed correspondingly to the bristle stand 32. A large number of bristles 41 are planted around the outer periphery of the Prinsle stand 32, and the structure is such that hot air is blown out from the base side toward the tip along the path indicated by the arrow X. (Cold air) is blown out to the vicinity of the outer periphery of the entire bristle 41 as shown by arrow Y, and the dryer-type roll brush blocks the hot air after being blown out. Then, the hair is wound between the bristles 41 by rotating the brush, and the motor 10 and heater 27 are turned on by operating the power switch 22 and changeover switch 23.
By setting it to N, hot air can be applied to the hair. In addition, since cold air is blown out to the vicinity of the outer periphery of the bristles 41 through the low-temperature air outlet 37, the hot air that is applied to the skin while the hair is wrapped around the skin one after another is blocked by the cold air. As a result, there is no risk of the hot air hitting the scalp or ears directly.This prevents the scalp from becoming excessively heated, and only the wrapped hair receives the hot air, making it efficient and efficient. This allows for effective drying and centrifugation, making it possible to provide a safe and easy-to-use setting device.Also, since the hot air does not hit unnecessary areas such as the skin, the hot air The temperature can be raised higher, and cents can be made more efficiently and effectively.In the above embodiment,
Since the heater 27 is provided with the heater enclosure frame 14 and the outer casing 3 is located with the low-temperature air passage 13 on its outer periphery, even under certain adverse conditions when the motor 10 is stopped and only the heater 27 is activated, Heat is not easily transmitted to the exterior casing 3, and there is no risk that the exterior casing 3 or the like will be deformed due to heating.

FIG. 4 shows an embodiment of a blow brush, in which a blow brush main body 42 is detachably attached to the body 2 as an axoment. Blow brush body 4
2 is equipped with a brush stand 31 on one side, and a hot air outlet/inlet 39 is formed in this brush stand 31. The brush stand 31 has a bristle bar 4 with bristles 41 planted thereon.

The hot air is blown out from the hot air passage 28 toward the tip of the prinsle 41 through the hot air guide path 38 and the hot air receiving port 39 as indicated by arrow X in FIG. Inside the blow brush main body 42, as shown in FIG.
The wind separation frame 46 is integrally formed with the wind separation frame 46 remaining, and the low temperature air (cold air) from the low temperature air passage 13 shown in FIG. 45
As shown in FIGS. 5 and 6, low temperature air is blown out to both sides of the entire bristle 41 through low temperature air outlets 37 arranged in columns on both sides of the bristle table 32. . At the same time, the main low temperature air outlet 3
7 is opened in a stepped portion on the base side of the blow brush main body 42. The low temperature air passage 13 passes through this low temperature air outlet 37.
Low-temperature air (cold air) is blown out like arrow Y,
The blowing of the hot air to the scalp is interrupted midway.

In this embodiment, in order to make the blow brush body 42 detachable from the body 2, the switch operation protrusion 25 of the power switch 22 is also used as an attachment/detachment operation means, as shown in FIGS. 7(a) and (bl). This is the configuration.Here, lock piece 3
4 is provided with a first cam surface 47 and is provided on the outer periphery of the front end side of the exterior casing 3, and is provided with a lock spring 48 between it and the exterior casing 3. The switch operation protrusion 25 is
The lock piece 34 has a second cam surface 49 which is an attachment/detachment operation part, and when the switch operation protrusion 25 is operated in the switch ON direction as shown in FIG. When the pressure from the piece 25 is released, the lock spring 48 springs into engagement with the engagement groove 35, and when the switch is operated in the OFF direction, the switch operating protrusion 25 is released, as shown in FIG. 7(b). The second cam surface 49 presses down the first cam surface 47 of the lock piece 34 so that the lock piece 34 is disengaged from the engagement groove 35. As a result, when the blow brush main body 42 is pushed in as shown in FIG. 7(a), it is automatically locked to the body 2 and the engagement is maintained, whereas when the blow brush main body 42 is pushed in as shown in FIG. 7(b), the blow brush can be freely moved. The main body 42 can be removed. In this case, since the switch operation protrusion 25 also serves as the attachment/detachment operation means, the structure is simplified and the number of parts is reduced, which is advantageous in terms of cost. This has the advantage that there is no risk of the attachment coming off during use.

In the above embodiment, the air that is sucked in is blown out as cold air (low-temperature air), but some hot air may be mixed with the cold air and blown out as low-temperature air that is lower than hot air. In the above embodiment, a structure was described in which the hot air is exclusively blocked by blowing low-temperature air across the hot air that is being blown out. However, as another mode of blocking, for example, a structure in which low-temperature air is mixed with the hot air that is being blown out has been described. In some cases, the temperature is lowered to a lower temperature, and this case is also included in the above-mentioned shutoff. In the above case,
It is best to mix with hot air after it hits the hair. In the above embodiment, a curl dryer having a brush has been described, but the present invention can also be applied to, for example, a general hair dryer for the purpose of drying.

[Effects of the Invention] As explained above, according to the present invention, the main body includes a hot air passage through which the hot air blown out from the hot air outlet passes, and a low temperature air passage through which the hot air that is blown out is blocked after being blown out. Since the passages are separate from each other, the scalp does not get hot, and moreover, hot air can be blown onto the hair, making it easier to use, efficient and effective. ) can be provided.
