In the mist generating section 9, a miss nozzle 25 is press-fitted into a mist nozzle fixing base 26 via an O-ring 27. Air is supplied to the air intake pipe 2 which is press-fitted into the coupling pipe 17.
The air is taken in from the air pipe 29 in the water tank 8 and sent from the air pipe 30 to the air supply port 31 of the mist nozzle 25 in the mist nozzle fixing table 26. Here, when air is sent into the mist nozzle 25 from the air supply port 31, a pressure drop occurs near the outer periphery of the mist nozzle 25 (the space sealed with the O-ring 27 within the mist nozzle fixing base 26), and the water Water in the tank 8 is sucked up through a suction pipe 32 disposed within the water tank 8 and reaches the mist nozzle 25 through a water suction pipe 33. At this time, the water is blown away by the airflow and becomes mist.

In this mist hair dryer, by driving the drive motor M, the fan 5 is rotated and the air pump section 6 is also driven. fan 5
When is driven, air is sucked in from the suction port 7 and discharged from the air outlet 2 to be blown. At this time, when the heater 3 is energized, it generates heat and hot air is blown, and when the heater 3 is not energized, cold air is blown. When the air pump section 6 is driven, air is sent to the mist nozzle 25 and mist is sprayed. Here, 34 is a nozzle ring 35 in the water tank 8.
It is a wind direction nozzle installed through the. 36 is High

Reference numerals 40 and 41 are front covers (40) that also have a rectifying function to prevent the air pipe 30 and water supply pipe 33 from being removed by fingers or the like from the outside, and to minimize pressure loss in the air flow of the hair dryer. It is a cover (41). As described above, since the mist generating part 9 and the main body housing 1 can be attached and detached with the above-described structure, the mist generating part 9 can be separated from the main body housing 1 when the mist is not in use, and the size can be kept almost the same as a conventional hair dryer. Compact and easy to handle.

Furthermore, as shown in FIGS. 1, 2, and 7, since the mist nozzle 25 is located approximately in the center in front of the air outlet 2, the fusion of mist and hot/cold air is more efficient than in the past. The process is much smoother than that of a mist hair dryer. It is also possible to blow the mist further by using the wind around the mist. FIG. 8 is a view of the mist generating section 9 seen from the front on the wind direction nozzle 34 side. The mist nozzle 25 is located approximately in the center of the opening 42 of the wind direction nozzle 34, and even if the wind direction nozzle 34 rotates, The location remains in the center.

The water tank 8 of the mist generator 9 is arranged in a ring shape around the air passage in front of the air outlet 2, as shown in FIGS. 7 and 10. 8' in FIG. 7 is also a water storage portion of the water tank 8. This allows water tank 8
is compactly constructed. Also, as shown in Figure 7,
The wind direction nozzle 34 is integrally formed at the tip of the mist generating section 9. Therefore, when drying the hair after washing, the mist generating part 9 and the wind direction nozzle 34 are not necessary, but the mist generating part 9 can be removed at the same time as the conventional wind direction nozzle is removed, which saves time and effort. Here, the wind direction nozzle 3
4 is a hook 8a of the water tank 8 (divided at 120 degrees on the circumference, there are two other places, for a total of three places) and a hook 34a of the wind direction nozzle 34 (divided at 120 degrees, there are two other places, for a total of three places) ) are coupled via a ring 43. As a result, the wind direction nozzle 34 can be rotated to a large extent in the water tank 8, but cannot be attached to or detached from the water tank 8. During assembly, the hook 8a is inserted into the ring 43 by bending. Once assembled, it cannot be removed by the user without tools. This non-removable configuration protects the mist nozzle fixing base 26 into which the mist nozzle 25 is inserted.

This waterproof permeable membrane 45 is a resin filter with pores of 0.5 to several microns, but it is a high-tech filter that allows air to pass through but not water due to surface tension. This waterproof permeable membrane 45 prevents the water in the water tank 8 from being pushed out from the mist nozzle 25 due to the positive pressure in the water tank 8. That is, normally when mist is generated, air is taken into the water tank 8 through an air intake valve (not shown) under negative pressure, but this valve does not function as an open valve when the pressure is positive. When only hot air is used in the mist off, the temperature inside the water tank 8 rises due to the heat of the hot air, and as a result, the pressure inside the water tank 8 rises, and water drips from the mist nozzle 25 due to the pressure. At the time of this positive pressure, air is released from the waterproof permeable membrane 45, so water dripping from the mist nozzle 25 is prevented.

The water supply lid 46 of the water tank 8 is provided on the side of the air outlet 2 of the main body housing 1 of the mist generating section 9, as shown in FIG. The water supply lid 46 connects to the water tank 8 at its fulcrum 47.
When the water supply lid 46 is pulled forward once and then moved in the direction of the arrow 48 around its fulcrum 47, a water supply port 49 (dotted line in FIG. 9) appears. By arranging the water supply lid 46 in this position, even if it is press-fitted into the water supply port 49 a little loosely, it will be pressed against the surface 50 of the air outlet 2 in FIG. 6 when the mist generating section 9 is attached to the main body housing 1. , a reliable press-fit state is achieved, and water does not leak from the water supply lid 46.

Furthermore, as shown in FIG. 7, the mist nozzle 2
The inner clearance between the O-rings 27 of the mist nozzle fixing base 26 on the outer periphery of 5 has a wire diameter of 40 μ, 250 mesh to 300
A dustproof filter 63 made of mesh and having a thickness of about 75 to 80 μm is inserted and set. As a result, the water supply port 4
The garbage that entered with the water from 9 is taken up by the suction pipe 32 and the water pipe 3.
3 to prevent the small holes 51 from being clogged by entering the mist nozzle 25.

Further, in FIG. 9, supporting ribs 65, 66 of the mist nozzle fixing base 26 and a blind cover 41 are provided, and these also serve as a rectifying blade for hot and cold air. Although FIG. 11 shows the handle portion 11 in a folded state, as shown in FIGS. This allows for compactness when not in use. The recesses 55 and 56 also serve as positioning for the mist generating section 9 when it is attached or detached.

In FIG. 12, a water absorbing body 52 is provided at the tip of the mist nozzle 25, the water absorbing body 52 is held by a water supply body cover 53, and the inner circumferential surface of the ring-shaped water tank 8 in front of the air outlet 2 is held. This is another embodiment in which water absorbers 54 are disposed around the entire circumference. These prevent water droplets from entering the main body housing 1 even when water droplets that have not become a mist are discharged from the mist nozzle 25. Water-supplied water absorber 52,
54 are arranged at these positions, the blower device 6
Drying can be performed using warm air obtained by operating the heater 3 and the heater 3.
