Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a hair iron that clips hair to create waves or straight hair.

[Conventional technology]

Conventionally, as this type of hair iron, for example, the one shown in FIG. 6 has been known (Japanese Utility Model Publication No. 54-61789). This is a device in which the hair is sandwiched between a pair of thick waving plates 30, 30 made of die-cast aluminum and each having a built-in heater 29 and waving the hair.

Further, as shown in FIGS. 7 and 8, hair clipping surfaces 31a and 32 each having a corrugated cross section are provided on the opposing surfaces of the hollow bobbin 31 and the clip 32, which face each other.
There is one in which the hair is sandwiched between the hair-pinching surfaces and heated with hot air blowing out from the bobbin 31 to wave the hair (Japanese Utility Model Publication No. 106102/1983).

[Problem that the invention attempts to solve]

However, in the former conventional example described above, the aluminum die-cast wave plate 30 is directly heated by the heater 29, so it takes a long time to heat the wave plate 30 to a usable temperature. 30, it stores a large amount of heat and does not cool down quickly, so if your skin comes into direct contact with the surface of the board, you are likely to get burns, and furthermore, you should use it only after washing your hair and thoroughly drying it. There are disadvantages and inconveniences such as not being able to do so.

On the other hand, according to the latter conventional example, the hair is waved while blowing hot air, so it can be warmed up quickly and used, and it does not get too hot, so there is no risk of getting burned. ,
Although hair has advantages such as being able to be used while drying even in a semi-dry state, it is still not sufficient and has the following disadvantages.

In other words, with this hot air hair iron,
Hot air is sent into the interior of the hollow bobbin 31 from a socket at one end in the longitudinal direction, and is blown out from a hot air outlet 33 opened in the hair-pinching surface 31a of the bobbin 31 to heat the hair.
Since the hair is constructed as a blind wall and does not allow hot air to pass through, even if the side of the hair sandwiched between the bobbin 31 and the clip 32 that contacts the bobbin 31 is heated, the side that contacts the clip 32 is difficult to heat. The disadvantage is that uneven heating occurs and it is difficult to apply waves uniformly over the entire hair.

Further, the metal plate 34 having the hair-pinching surface 31a on the side of the bobbin 31 is configured as a perforated plate having a large number of hot air blowing holes 33, but since the perforated metal plate 34 has a large number of holes 33, its mechanical strength is low. Easy to chip,
If the hair is deformed by the pinching pressure of the hair, it will not be possible to create the desired waves, so a thick plate will be used. However, as the porous metal plate 34 becomes thicker, the depth of the blow-off holes 33 becomes larger, which tends to increase the ventilation resistance, and also increases the weight, making it difficult to use.

This idea was made to eliminate the drawbacks caused by conventional hot-air hair irons, and by devising ways to pass air through the pair of wave plates, the hair can be heated evenly and evenly. The primary objective is to be able to do this efficiently.

In addition, by devising the way the wave board is attached to the holding case, this design aims to make the wave board as thin as possible to reduce ventilation resistance, improve ease of use by making it lighter, and further reduce the wave shape due to the thinner wall. The second purpose is to prevent deterioration in shape retention and improve lamination workability.

[Means for solving problems]

This invention takes the following measures to achieve the first and second objects mentioned above. That is, this invention consists of a hot air supply means 1 and a pair of wave plates 2 and 3 each having a corrugated cross section and stretched over the opposing surfaces of opposing wave plate holding casings 12 and 13 so as to be able to sandwich hair freely. , hot air supply means 1
The hair iron is assumed to have a number of ventilation holes 10 opened in a wave plate 2 on the hot air supply side for blowing hot air supplied from the hair onto the hair.

In addition, in order to achieve the above-mentioned first objective, this invention provides a large number of ventilation holes 11 in the wave plate 3 on the exhaust side, which is opposite to the wave plate 2 on the hot air supply side, through which the hot air after heating the hair passes. establish. In addition,
The wave plates 2 and 3 are made of punched metal, wire mesh plates, or the like.

In addition, in order to achieve the above-mentioned second object, this invention also has the purpose of receiving at least the inner surfaces of the chevron portions 2a and 3a of the wave plates 2 and 3 on the respective wave plate bonding surfaces of the wave plate holding casings 12 and 13. Supporting ribs 19 and 21 are provided.

[Effect]

In such a case, if the hair H is sandwiched between the wave plates 2 and 3 and hot air is supplied from the hot air supply means 1 toward one of the wave plates 2, the hot air will flow to the wave plate 2.
The hair is heated and deformed through the ventilation hole 10 of the other wave board 3, and further passes through the hair and is discharged from the ventilation hole 11 of the other wave board 3 to the rear side thereof. Furthermore, ribs 19,
Even if the wave plates 2 and 3 received and supported by 21 are thin, they will not be easily deformed by the pinching pressure of the hair and cause the waves to lose their shape.

[Effect of idea]

The hair iron of this invention has two wave plates,
3 are provided with a large number of ventilation holes 10, 11, the hot air can pass through the hair between the waving plates 2, 3, and the entire hair in contact with the waving plates 2, 3 can be uniformly and efficiently distributed. It can be heated and waved. Moreover, the wave plate holding case 12,1
Rib 1 provided on each wave board bonding surface of 3
9 and 21 are intended to receive and support at least the inner surfaces of the chevron portions 2a and 3a of the wave plates 2 and 3, so the wave plates 2 and 3 are made of thin plates in order to reduce ventilation resistance and reduce weight. However, the wave plates 2 and 3 can be prevented from being deformed by the pinching pressure of the hair. Further, the wave plates 2 and 3 are aligned with the ribs 19 and 21, and the holding casing 12,
By pasting them together on the bonding surfaces of the wave plates 13, they can be easily and reliably held and fixed at predetermined positions on the holding casings 12 and 13, and the work of bonding them can be easily performed.

〔Example〕

An embodiment of the hair iron according to this invention will be described below with reference to FIGS. 1 to 4. This hair iron consists of a hot air supply means 1 and a pair of upper and lower wave plates 2 and 3. The hot air supply means 1 utilizes a hair dryer, to which wave plates 2 and 3 are removably attached as attachments.

The hair dryer, which is a hot air supply means 1, has a heat generating part 5 by a heater, a motor 6, and an axial fan 7 arranged side by side in order from the front inside a main body case 4 which is elongated in the longitudinal direction. Then, a hot air outlet 8 was provided on the front lower surface of the main body case 4, and a suction port 9 was provided on the rear thereof, and the fan 7 was rotated by the motor 6 to suck air from the suction port 9, and the air was heated by the heat generating part 5. Afterwards, the hot air is blown out downward from the air outlet 8.

The pair of wave plates 2 and 3 are each formed by bending a thin punched metal into a corrugated cross section, and have a large number of ventilation holes 10 and 11, and are vertically opposed wave plate holding cases 12 and 13 each having a dish-shaped cross section. It is fitted into the opposing recesses 12a and 13a and pasted together.

The wave plate holding casings 12 and 13 are integrally formed at the respective tips of plastic grip plates 15 and 16 whose rear ends are rotatably connected to each other by a support shaft 14. A spring 17 is mounted on the support shaft 14 between the grip plates 15 and 16 to always bias the grip plates 15 and 16 to open.

The upper wave plate holding case 12 has a hot air supply port 18 opened on its back side, and a plurality of ribs 19 are positioned below the hot air supply port 18 between the front and rear frames 12b and 12c in this holding case 12. The wave plate 2 extends over the entire length of the top inner surface of the chevron-shaped portion 2a in the front-rear direction and connects to the rib 19.
It is pasted together so that it can be received and supported. On the other hand, the lower wave plate holding case 13 has a large number of blow-off holes 20 formed on its back side, and a plurality of ribs 2 above the blow-off holes 20 in the holding case 13.

Like the wave plate 2, the top inner surface of the chevron-shaped portion 3a is pasted together so that it is received and supported by the ribs 21 over its entire length in the front-rear direction.

The hot air supply port 18 opened on the back side of the upper wave plate holding case 12 is formed to match the opening size and shape of the hot air outlet 8 of the hair dryer, which is the hot air supply means 1, and is A U-shaped boss 22 in a plan view that surrounds only the right, left, and front sides of the mouth 18 is provided. The boss 22 of the holding housing 12 is inserted from the front into longitudinally long flanges 23, 23 formed at the left and right opening edges of the hot air outlet 8 of the hair dryer. It slides backward until it matches the position directly below No. 8 and is fixed. Then, as shown in Fig. 2, the upper grip plate 1
5 is attached to the lower surface of the main body case 4. Note that a protrusion 24 protruding from the front of the boss 22 is recessed into a recess 25 at the front of the hot air outlet 8.
By fitting the wave plates 2 and 3 into the body case 4, the wave plates 2 and 3 are prevented from slipping out to the front of the main body case 4.

Next, how to use the hair iron having the above structure will be explained. Grasp the main body case 4 and lower grip plate 16 of the hot air supply means 1, and sandwich the hair H between the wave plates 2 and 3 as shown in FIG. That hair H is
It is heated by the hot air blown out from the hot air outlet 8 of the hot air supply means 1 and passes through the hot air supply port 18 and the ventilation hole 10, thereby forming waves that match the corrugated cross sections of the wave plates 2 and 3. At this time, since the hot air supply port 18 is disposed on the back side directly above the upper wave board 2, the hot air is blown uniformly over all the ventilation holes 10 of the wave board 2. Further, the hot air applied to the hair is discharged outward from the ventilation holes 11 of the lower wave plate 3 through the blow-off holes 20, so that the hot air can pass through the hair easily. Furthermore, since the wave plates 2 and 3 are supported by the ribs 19 and 21 on the wave plate holding casings 12 and 13, even if they are thin, they do not easily deform due to the pinching pressure of the hair, and the wave shape is maintained. It has excellent shapeability and allows for accurate application of waves.
