  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, preferred embodiments of the invention will be described in detail with reference to the drawings. Note that similar components are included in the following embodiments. Therefore, in the following, common reference numerals are given to similar components, and redundant description is omitted.

  (First Embodiment) FIGS. 1 to 3 show a hair care apparatus according to a first embodiment of the present invention. FIG. 1 is a cross-sectional side view of an essential part of a blower air passage of a hair dryer, and FIG. 1 is a cross-sectional view taken along the line II-II in FIG. 1, and FIG. 3 is an enlarged cross-sectional view of a portion III in FIG.

  The hair dryer 1 as the hair care device according to the present embodiment is formed with the air passage 3 that generates the air flow AF in which the air introduced from the air suction port 3a by the blower fan 2 is blown out as the air blow B from the air blowout port 3b. ing. A nozzle (not shown) is attached to and detached from the air outlet 3b as necessary.

  The air blowing path 3 is formed as the inside of the cylindrical outer shell 4. The cylindrical shell 4 is connected with a grip portion 5 extending in a direction intersecting therewith.

  A heater 6 is disposed on the downstream side of the blower fan 2 in the blower passage 3. By operating the heater 6, the airflow AF is heated and hot air is blown out from the air outlet 3 b, while the heater 6 The cold air is blown out by stopping the operation. The grip 5 is provided with a switch 7 for switching the operation (ON / OFF) of the blower fan 2 and the heater 6 and adjusting the air volume.

  In this embodiment, the blower fan 2 is configured as an axial fan that rotates a fan blade 2b by a motor 2a. The blower fan 2 is not limited to the axial flow type, and may be any fan type that can blow air, such as a sirocco fan or a centrifugal fan.

  The heater 6 is constructed by assembling a heat-resistant thin plate 6a such as mica in a cross-shaped cross section and winding an electric resistance heating wire 6b such as a nichrome wire around the outer periphery thereof.

  The outer periphery of the heater 6 is surrounded substantially concentrically with the cylindrical outer shell 4 by a heat-resistant cylindrical plate 6 c having a smaller diameter than the cylindrical outer shell 4. Therefore, the air flow AF is divided into a flow passing through the inside of the heat-resistant cylindrical plate 6c and a flow passing outside the heat-resistant cylindrical plate 6c, that is, between the heat-resistant cylindrical plate 6c and the cylindrical outer shell 4. The

  Here, in the present embodiment, the liquid tank 10 is installed so that at least a part of the air flow AF in the air passage 3 is exposed, and the upstream side wall 10a and the downstream side wall 10b exposed in the air passage 3 are predetermined. The portion is formed of vapor permeable membranes 11 and 12 having waterproof and moisture permeable properties, respectively. The vapor permeable membranes 11 and 12 are membranes that allow passage of a liquid such as water in a liquid phase state while allowing passage of the liquid in a gas phase such as air or steam.

  The liquid tank 10 is formed by a sealed, substantially rectangular parallelepiped container, and the liquid tank 10 is disposed in the vicinity of the air outlet 3b in the upper space S between the heat-resistant cylindrical plate 6c and the cylindrical outer shell 4. Thus, the air flow AF collides with the liquid tank 10.

  At this time, in the liquid tank 10, the passage resistance of the upstream vapor permeable membrane 11 is made smaller than the passage resistance of the downstream vapor permeable membrane 12.

  That is, a large opening 10c is formed in the upstream side wall 10a of the liquid tank 10 with a vertical width substantially equal to the upper space S between the heat-resistant cylindrical plate 6c and the cylindrical shell 4, as shown in FIG. The upstream vapor permeable membrane 11 is attached to the large opening 10c and sealed. Similarly, the downstream side wall 10b of the liquid tank 10 is formed with a small opening 10d smaller than the vertical width of the upper space S described above, and the downstream vapor permeable membrane 12 is attached to the small opening 10d. And sealed.

  In this way, by increasing the area of the upstream vapor permeable membrane 11 and reducing the area of the downstream vapor permeable membrane 12, a difference in both passage resistances is provided. Further, in the present embodiment, the passage resistance of both is made different by making the upstream vapor permeable membrane 11 thinner and also making the downstream vapor permeable membrane 12 thicker.

  In the present embodiment, the liquid tank 10 is disposed on the outer periphery of the heater 6, but the heat tank 13 is interposed between the liquid tank 10 and the heater 6, and the liquid tank 10 is made by the heater 6. Heating is suppressed.

  Specifically, in this embodiment, a heat-resistant cylindrical plate 6c is interposed between the liquid tank 10 and the heater 6, and the liquid tank 10 is installed on the outer periphery of the heat-resistant cylindrical plate 6c. As described above, the heat shield member 13 is attached to the inner periphery of the heat-resistant cylindrical plate 6c where the liquid tank 10 is installed. The heat shield member 13 can be formed of a member having heat resistance and low thermal conductivity, such as ceramic.

  The upper end portion of the liquid tank 10 protrudes outward from a mounting hole 4 a formed in the cylindrical outer shell 4. At this time, a liquid inlet (not shown) is provided at the upper end of the liquid tank 10 protruding from the mounting hole 4a. In the present embodiment, water is used as the liquid, and water is stored in the liquid tank 10.

  In the hair dryer 1 having the above configuration, when the air blowing fan 2 is operated by operating the switch 7, the air flow AF is generated in the air blowing path 3 by the air introduced from the air inlet 3a, and the air blown out from the air outlet 3b. Is done.

  At this time, in this embodiment, as described above, the liquid tank 10 that is at least partially exposed in the air flow AF of the air passage 3 is provided, and the upstream side wall 10a and the downstream side wall 10b that are exposed in the air passage 3 are provided. The predetermined portions (large opening 10c and small opening 10d) are formed by vapor permeable membranes 11 and 12, respectively. Therefore, when the air flow AF collides with the upstream vapor permeable film 11, a part of the collided air passes through the vapor permeable film 11 and enters the liquid tank 10.

  Then, the stored water is discharged in a vapor state from the downstream vapor permeable membrane 12 on the opposite side so as to be pushed out by the air that has entered the liquid tank 10, and the discharged vapor is discharged into the air outlet 3b. It mixes in the ventilation B which blows off from, and the ventilation B can be humidified.

  Therefore, in the present embodiment, when humidifying the blower B, the liquid tank 10 provided with the upstream and downstream vapor permeable membranes 11 and 12 exposed in the blower path 3 may be appropriately disposed, and the entire apparatus Thus, it is possible to obtain a hair dryer 1 that is more user-friendly.

  Further, in this embodiment, the passage resistance of the upstream vapor permeable membrane 11 provided in the liquid tank 10 is made smaller than the passage resistance of the downstream vapor permeable membrane 12. For this reason, air easily enters the liquid tank 10 from the upstream vapor permeable membrane 11. Therefore, the amount of steam released from the downstream vapor permeable membrane 12 can be increased, and the humidification efficiency can be increased.

  Further, in the present embodiment, a heat shield member 13 is provided between the heater 6 and the liquid tank 10. Thereby, since it can suppress that the liquid tank 10 is heated with the heater 6, it suppresses that the water in the liquid tank 10 evaporates excessively, and it becomes easy to obtain a more suitable humidification state.

And the predetermined part of the upstream side wall 10a and the downstream side wall 10b of the liquid tank 10 exposed in the ventilation path 3 is formed with the vapor permeable films 11 and 12, respectively.

  However, in the present embodiment, as shown in FIG. 5, at least a part of the downstream vapor permeable membrane 12 is exposed to the outside of the air passage 3 in the vicinity of the air outlet 3b. This is different from the embodiment.

  That is, the amount of protrusion that the liquid tank 10 protrudes outward from the mounting hole 4a of the cylindrical outer shell 4 is larger than that of the first embodiment, and the downstream side wall 10b is small in a portion protruding outward from the cylindrical outer shell 4. An opening 10d is formed, and a downstream vapor permeable membrane 12 is attached to the small opening 10d and sealed.

  Therefore, according to the hair dryer 1A according to this embodiment, the predetermined portions of the upstream side wall 10a and the downstream side wall 10b that are exposed in the air passage 3 are formed by the vapor permeable membranes 11 and 12, respectively. Similarly, water can be discharged in a vapor state from the downstream vapor permeable membrane 12 by the air flow AF.

  In particular, in the present embodiment, since at least a part of the downstream vapor permeable membrane 12 is exposed outside the air blowing path 3 in the vicinity of the air outlet 3b, the vapor released from the vapor permeable membrane 12 is The air can be drawn and sent together with the air blow B blown out from the air outlet 3b. In addition, when using hot air, the influence of hot air on the steam discharged from the downstream vapor permeable membrane 12 can be suppressed, so that the liquid spray state can be further stabilized regardless of whether the air is hot air or cold air. .

  Also in this embodiment, it is preferable that the passage resistance of the upstream vapor permeable membrane 11 is smaller than the passage resistance of the downstream vapor permeable membrane 12, and between the liquid tank 10 and the heater 6. It is preferable to suppress the heater 6 from heating the liquid tank 10 by interposing the heat shielding member 13 therebetween.
