Description

  The present invention relates to a hair dryer used for hair styling and the like.

  Hair dryers are widely used at home as electric appliances for drying hair after shampooing. In general, a hair dryer is provided between a blower outlet and a fan, a cylindrical main body having a blowout opening at the tip, a fan for blowing air provided in the main body, a motor for rotating the fan, and a fan. The air blown by the rotation of the fan is heated by the heater and discharged from the outlet.

  However, in the conventional hair dryer, the hot air from the outlet is only unilaterally blown to the head, so the head may feel hot due to the hot air during the operation of the dryer. Especially in the hot season, the hot air from the dryer is often uncomfortable. In addition, since the hot air from the outlet remains discharged, the air in the air-conditioned room may be heated, or the air in the room may be polluted with the smell mixed with the hot air, which may cause discomfort.

  On the other hand, in the field of hand dryers used for hand drying, many proposals have been made to prevent air pollution by circulating hot air, for example, as described in Patent Documents 1 to 4 listed later. Has been. In any of these air circulation dryers, the generated hot air is recovered by an air recovery means provided inside the apparatus and circulated without being discharged to the outside. However, in the case of a hair dryer, unlike the hand dryer, the original function cannot be achieved unless hot air is discharged to the outside. Therefore, the above-described air circulation structure of the hand dryer cannot be used as it is. For this reason, in order to solve problems such as unpleasant feeling due to hot air and air pollution in the hand dryer, a circulation mechanism specific to the hand dryer is required.

  FIG. 1 is a view showing an embodiment of a hair dryer according to the present invention, in which (a) is a front sectional view and (b) is a sectional view taken along line XX of (a). The hair dryer 100 includes a main body 1, a cylindrical body 2 disposed around the main body 1, a switching plate 3 disposed between the rear end of the main body 1 and the rear end of the cylindrical body 2. And a grip 15 connected to the main body 1.

  The main body 1 is formed in a substantially cylindrical shape with a bottom, and a tip portion thereof is a tapered portion 1a, and a blowout port 10 is opened at the tip of the taper portion 1a. A plurality of air inlets 1 b are provided at the rear end (bottom) of the main body 1. Reference numeral 12 denotes a fan for blowing air provided inside the main body 1, 13 denotes a motor for rotationally driving the fan 12, and 14 denotes a heater provided between the outlet 10 and the fan 12.

  The cylindrical body 2 is also formed in a substantially cylindrical shape with a bottom, and a tip portion thereof is a tapered portion 2a that expands at a predetermined angle, and an opening portion 11 is formed at the tip of the tapered portion 2a. Yes. A plurality of air inlets 2b are provided at the rear end (bottom) of the cylindrical body 2. As shown in FIG. 1B, the cylindrical body 2 has an inner diameter d2 that is larger than the outer diameter d1 of the main body 1, and is disposed around the main body 1 so as to surround the main body 1. . As a result, an intake passage 8 for circulating air is formed between the main body 1 and the cylindrical body 2. The intake passage 8 communicates with the intake port 1 b of the main body 1. The cylindrical body 2 is fixed to the main body 1 or the grip portion 15 (or both) by a fixing member (not shown).

  The switching plate 3 is a disk-shaped plate having a diameter substantially equal to the inner diameter d2 of the cylindrical body 2, and is provided so as to be movable in the arrow ab direction by a switching mechanism (not shown). The switching plate 3 has a plurality of through holes 3a. These through holes 3a are formed at positions corresponding to the air inlets 1b of the main body 1 and the air inlets 2b of the cylindrical body 2. It is formed so that the position shifts. In the state of FIG. 1, the switching plate 3 is in contact with the cylindrical body 2, and the air inlet 2 b of the cylindrical body 2 is blocked by the switching plate 3.

  The grip portion 15 includes a switch 16 that is turned on and off by a manual operation, and a power cord 17 for supplying a current to the motor 13 and the heater 14. The grip 15 supports the main body 1 and is led out from the cylindrical body 2 to the outside.

  In the hair dryer 100 having the above configuration, when the switch 16 is turned on, the motor 13 is driven to rotate the fan 12, and the wind generated by the fan 12 is sent forward as indicated by a broken line A. Further, the heater 14 generates heat when energized, and the wind from the fan 12 is heated by the heater 14 and sent to the outlet 10 as indicated by a broken line B. As a result, the hot air 4 is discharged from the outlet 10 and is blown to the head 5 of the human body. A broken line 6 indicates a region where the hot air 4 is blown. By blowing the hot air 4, the hair of the head 5 is dried. On the other hand, the blown hot air 4 is reflected and diffused by the head 5. A broken line 7 indicates a diffused region of the reflected hot air.

  In FIG. 1, as described above, since the air inlet 2 b of the cylindrical body 2 is blocked by the switching plate 3, a part of the hot air reflected and diffused by the head 5 is rotated by the rotation of the fan 12. Then, it is sucked into the opening 11 as indicated by a broken line C, passes through the intake passage 8 as indicated by a broken line D, and flows into the inside of the main body 1 from the intake port 1b as indicated by a broken line E. The inflowing hot air is sent out again by the fan 12, heated by the heater 14, and discharged from the outlet 10. In this way, air is circulated along the route of A → B → C → D → E → A.

  According to the above-described embodiment, the used hot air reflected from the head 5 while discharging the hot air 4 from the outlet 10 passes through the intake passage 8 between the main body 1 and the cylindrical body 2 and the main body 1. Therefore, a part of the hot air 4 blown out from the blowout port 10 can be collected and circulated. For this reason, by quickly collecting the air with residual heat in the vicinity of the head 5, the discomfort caused by exposure to the hot air 4 is reduced even in the hot season, and the surrounding air is heated unnecessarily. It is possible to effectively prevent the air from being polluted by the odor mixed with the hot air 4. Moreover, it is realizable with the simple structure which only provides the cylindrical body 2 around the main body 1, and a small and lightweight product can be provided.

  Further, in FIG. 1, the switching plate 3 is movable in the direction of the arrow ab, so that air is not circulated by switching the switching plate 3 so as to contact the main body 1 as shown in FIG. It can also be.

Therefore, as the fan 12 rotates, outside air is taken into the main body 1 through the air inlet 2b, the through hole 3a, and the air inlet 1b as shown by the broken line F. The taken-in air is sent out by the fan 12, heated by the heater 14, and discharged from the outlet 10. On the other hand, since the intake path 8 and the intake port 1b are separated by the switching plate 3, even if the fan 12 rotates, air suction input does not act on the opening 11, so that it is reflected and diffused by the head 5. Hot air does not flow into the intake passage 8 from the opening 11. That is, no air is circulated.

  In this way, by switching the position of the switching plate 3, a circulation operation (first operation mode) for sucking the air discharged from the outlet 10 into the intake passage 8 as shown in FIG. 1, and FIG. It is possible to select a non-circulation operation (second operation mode) in which the air discharged from the outlet 10 is not sucked into the intake passage 8. For this reason, for example, by selecting a circulation operation in the summer, it is possible to reduce the heat by sucking in the remaining heat air, and in a winter, the intake of the remaining heat air can be performed by selecting the non-circulation operation. Drying can be accelerated.
