Brief Description of the Drawings

[0013] [Figure 1] This is a schematic explanatory view of the present embodiment. [Figure 2] This is an enlarged schematic explanatory view of the main part of the present embodiment. [Figure 3] This is an enlarged schematic explanatory view of the main part of an alternative example. [Figure 4] This is an enlarged schematic explanatory view of the main part of a conventional example.

Modes for Carrying Out the Invention

[0014] Embodiments of the present invention considered to be suitable will be briefly described based on the drawings while showing the operation of the present invention.

[0015] The lengthwise dividing grooves 15 and 16 for discharging steam (reducing airtightness) can be arranged dispersedly in the width direction. Compared with the conventional configuration in which a groove portion is provided only at the center in the width direction, steam can be discharged more efficiently, and the region where steam is sealed can be made as narrow as possible. That is, a steam explosion caused by the sealing of steam is less likely to occur, and hair damage is suppressed accordingly.

[0016] For example, when a first heating plate 11 and a second heating plate 12 are arranged in parallel between them via a lengthwise first dividing groove 15 on a first clamping body 1, and a third heating plate 13 and a fourth heating plate 14 are arranged in parallel between them via a lengthwise second dividing groove 16 on a second clamping body 2, and the opposing first heating plate 11 and third heating plate 13 are heated to a high temperature and the opposing second heating plate 12 and fourth heating plate 14 are heated to a low temperature to clamp hair, in the conventional example shown in FIG. 4, steam discharge in the high-temperature region A' where particularly a large amount of steam is generated is insufficient and a steam explosion is likely to occur. On the other hand, according to the present invention, as shown in FIG. 2, steam in the high-temperature region A can be discharged well from the lengthwise second dividing groove 16 existing in front of the high-temperature first heating plate 11, and a configuration in which a steam explosion is less likely to occur can be realized. <00)0088>

[0017] Moreover, even if all the heating plates 11, 12, 13, and 14 are set to a high temperature, in the conventional example of FIG. 4, there is only one location where steam can be discharged in the width direction of the first clamping body 1 and the second clamping body 2. In contrast, according to the present invention, as shown in FIG. 2 (and FIG. 3 described later), there are two locations where steam can be discharged in the width direction, so it becomes possible to discharge steam more efficiently.

[0018] Furthermore, when clamping and heating hair, naturally, steam generated at the heating location needs to be discharged. Therefore, as compared with the case where there are only dividing grooves outside the heating section (the front surface of the heating plate) as in the conventional example of FIG. 4, having dividing grooves in the heating section as shown in FIG. 2 (and FIG. 3) enables more efficient steam discharge. Thus, the present invention can improve the steam discharge efficiency in various usage environments compared with the conventional example.

[0019] Also, instead of recessing grooves on the surface of a single heating plate, a configuration is adopted in which a plurality of independent heating plates are arranged in parallel at a predetermined interval and a lengthwise dividing groove is provided between the heating plates. Therefore, the surfaces (top surface and side surfaces) of each heating plate can be made flat. For example, when a fluororesin film for improving the slipperiness of hair is provided on the surface of the heating plate, it can be well adhered to the entire surface (when there are grooves on the surface, it is difficult to make the fluororesin film follow and adhere to the inner side surface and bottom surface of the grooves).

Embodiment

[0020] A specific embodiment of the present invention will be described based on the drawings.

[0021] This embodiment is a straight hair iron having a first clamping body 1 and a second clamping body 2. The first clamping body 1 is provided with a first heating portion 3 having a predetermined width and a predetermined length in the length direction of the first clamping body 1. Also, the second clamping body 2 is provided with a second heating portion 4 having a predetermined width and a predetermined length in the length direction of the second clamping body 2.

[0022] Specifically, as shown in Figure 1, the first clamping body 1 and the second clamping body 2 are connected so as to be able to open and close around their base ends, and are configured so that when an operator grips them, the first heating part 3 and the second heating part 4 provided at the tip side can clamp and heat the hair. The first clamping body 1 and the second clamping body 2 are biased to separate from each other by a biasing member such as a spring (not shown) when not being operated by an operator.

[0023] The first heating section 3 and the second heating section 4 are configured to have approximately the same width and length. Each of the first heating section 3 and the second heating section 4 includes a heating plate that is heated by the application of electricity. As the heating plate, for example, a known ceramic heater capable of heating to approximately 40°C to 230°C can be used.

[0024] In this embodiment, the first heating section 3 has a first heating plate 11 and a second heating plate 12, which are elongated and rectangular in shape in plan view, extending in the longitudinal direction of the first clamping body 1. The first heating plate 11 and the second heating plate 12 are arranged side by side in the width direction of the first clamping body 1 with a first longitudinal dividing groove 15 between them. That is, the first longitudinal dividing groove 15 is arranged to divide the heating plates 11 and 12 of the first heating section 3.

[0025] Furthermore, the second heating section 4 has a third heating plate 13 and a fourth heating plate 14, which are elongated and rectangular in shape in plan view, extending in the longitudinal direction of the second clamping body 2. The third heating plate 13 and the fourth heating plate 14 are arranged side by side in the width direction of the second clamping body 2 with a second longitudinal dividing groove 16 between them. That is, the second longitudinal dividing groove 16 is positioned to divide the heating plates 13 and 14 of the second heating section 3.

[0026] The heating plates 11 and 12 of the first heating section 3 and the heating plates 13 and 14 of the second heating section 4 are flat surfaces whose opposing surfaces (top surfaces) are parallel to each other when gripping hair.

[0027] Furthermore, as shown in Figure 2, this embodiment is configured such that the first heating plate 11 and the third heating plate 13 face each other, and the second heating plate 12 and the fourth heating plate 14 face each other, with the first heating plate 11 and the third heating plate 13 having different widths, and the second heating plate 12 and the fourth heating plate 14 having different widths. In this embodiment, the first heating plate 11 and the fourth heating plate 14 also face each other.

[0028] Furthermore, in this embodiment, when viewed from the opposing directions of the first clamping body 1 and the second clamping body 2, the first longitudinal dividing groove 15 and the second longitudinal dividing groove 16 are positioned so as not to overlap with each other.

[0029] Furthermore, in this embodiment, the first heating plate 11 has a wider width than the second heating plate 12, and the fourth heating plate 14 has a wider width than the third heating plate 13. In addition, the first longitudinal dividing groove 15 and the second longitudinal dividing groove 16 have narrower widths than the second heating plate 12 and the third heating plate 13.

[0030] Furthermore, in this embodiment, the first heating plate 11 and the fourth heating plate 14 are set to approximately the same width, the second heating plate 12 and the third heating plate 13 are set to approximately the same width, and the first longitudinal dividing groove 15 and the second longitudinal dividing groove 16 are set to approximately the same width. Note that the widths of each heating plate and dividing groove are not limited to these and can be set as appropriate.

[0031] Furthermore, this embodiment includes a control unit that controls the first heating plate 11 and the third heating plate 13 to a first temperature, and controls the second heating plate 12 and the fourth heating plate 14 to a second temperature different from the first temperature.

[0032] For example, if the first temperature is set to around 40°C to 60°C and the second temperature to around 180°C to 200°C, and the hair is heated from top to bottom with the upper direction in the diagram representing the hair roots, a soft and resilient finish can be achieved. Conversely, if the first temperature is set to around 180°C to 200°C and the second temperature to around 40°C to 60°C, and the hair is heated from top to bottom in the same manner, a hard and shiny finish can be achieved.

[0033] Even at high temperatures of around 180°C to 200°C, the steam is effectively released through the divided grooves 15 and 16, minimizing hair damage as much as possible.

[0034] Furthermore, in this embodiment, a fluororesin film (not shown) is provided on the surface of each heating plate 11, 12, 13, and 14. Each heating plate 11, 12, 13, and 14 has rounded corners in a cross-sectional view, and the fluororesin film is attached so as to cover the top and sides of each heating plate 11, 12, 13, and 14 (with the film stretched taut from the bottom end of one side to the bottom end of the other side).

[0035] Furthermore, although this embodiment is configured as described above, it may also be configured to have more than four heating plates. Also, although this embodiment is configured so that the first heating section 3 and the second heating section 4 each contain two heating plates, it may also be configured so that one contains one heating plate and the other contains three, as shown in the alternative example in Figure 3. In Figure 3, the first heating section 3 contains one heating plate 11, and the second heating section 4 contains three heating plates 12, 13, and 14, with a longitudinal dividing groove 15 between heating plate 12 and heating plate 13, and a longitudinal dividing groove 16 between heating plate 13 and heating plate 14. In this case as well, the longitudinal dividing grooves for discharging steam can be arranged in a distributed manner in the width direction.

[0036] In other words, the first heating section 3 and the second heating section 4 can be appropriately configured as long as they include at least a total of four heating plates 11, 12, 13, and 14, and at least two longitudinal dividing grooves 15 and 16 provided between each of the heating plates 11, 12, 13, and 14 arranged in the width direction.

[0037] As this embodiment is configured as described above, the longitudinally divided grooves 15 and 16 for releasing steam (reducing airtightness) can be distributed in the width direction. Compared to the conventional configuration in which grooves were provided only in the center in the width direction, this makes it possible to release steam more efficiently and to narrow the area in which steam is sealed as much as possible. In other words, steam explosions caused by the sealing of steam are less likely to occur, and hair damage is suppressed accordingly.

[0038] Furthermore, instead of creating grooves on the surface of a single heating plate, the configuration involves arranging multiple independent heating plates side by side at predetermined intervals and providing longitudinally dividing grooves between them. This allows the surface (top and sides) of each heating plate to be flat, and for example, when a fluororesin film is applied to the surface of the heating plate to improve hair glide, it can adhere well to the entire surface (if grooves are present on the surface, it is difficult to make the fluororesin film adhere to the inner and bottom surfaces of the grooves).

[0039] Therefore, this embodiment provides a straight hair iron that can more efficiently discharge the steam generated when heating hair. [Explanation of Symbols]
