Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a heating and cooling helmet device, and more particularly to a heating and cooling helmet device that can heat or cool the inside of the helmet using an internal thermoelectric element. .

[Prior Art] Conventionally, motorcycle riders, construction workers, and the like have traditionally worn helmets mainly for safety reasons.

The helmet used at this time is a motorcycle helmet to prevent head injuries from falling, and a construction helmet to prevent head injuries from objects falling from above. It was intended to prevent this.

Therefore, the entire structure is made to have strength.

By wearing it, you can prevent injuries.

[Problem to be Solved by the Invention 1] However, in such conventional helmets, the entire helmet is made of a rigid body in order to provide strength, so there is no air circulation, and the head may swell, especially in hot summers. It was also happening.

Therefore, in order to improve safety by wearing a helmet, on the contrary, the temperature inside the helmet impairs one's ability to think or make decisions, and as a result.

Wearing a helmet actually resulted in more accidents.

Also, in the winter, helmets were cold and I felt cold when I wore them.

Therefore, although the present invention is a small device, there is no unpleasant vibration or noise, and furthermore, it can be cooled or heated simply by operating a switch, and when it is particularly hot, the interior is cooled in inverse proportion to the heat. The purpose of providing a helmet is to prevent safety, reduce judgment in hot weather, and provide heating in cold weather.

For this purpose, the present invention uses a thermoelectric element as a heating/cooling device.

Here, the thermoelectric element is an element that causes energy conversion between heat and electricity, and cools one side by passing an electric current, and heats the other side with the same amount of heat in absolute value. Furthermore, in this thermoelectric element, the cooling surface and the heating surface can be changed by simply reversing the current direction.

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention incorporates a thermoelectric element and a heat storage agent in contact with one side of the thermoelectric element inside the helmet. A heat radiation part and a solar cell part are provided on the outer surface, and the other side of the thermoelectric element and the heat radiation part are connected by an electric heating element, and the thermoelectric element and the solar cell of the solar cell part are electrically connected. It is characterized by

[Embodiments] Hereinafter, embodiments of the present invention shown in FIGS. 1 and 2 will be described together with illustrated examples.

FIG. 1 is a perspective view of the helmet 10, and FIG. 2 is a sectional view thereof.

In the figure, helmet 10 is a helmet used when riding a motorcycle.

This is a type in which the front part of the main body 11 is cut out and a collar 12 is provided at the front part.

Also, as for the parts that can be seen from the outside, a solar cell section 20 is provided on the upper surface of the central portion of the helmet 10, and a heat sink 30 as a heat dissipation section is provided around the lower part of the solar cell section 20.

Further, a thermoelectric element 40 is provided inside the helmet IO, and one side of the thermoelectric element 40 is connected to a heat transfer body 31.
It is connected to the heat dissipation plate 30 by the heat dissipation plate 30, and the other side is brought into contact with the heat storage agent 50. Note that hanging downward from the lower part of the helmet 1O is a belt 13 for fixing the helmet 1O to the head.

The solar cell section 20 is formed from a solar cell 21 fixed to the bottom surface of the recess 14 of the helmet 10, and a protective material 22 provided so as to cover the surface of the solar cell 21. This protective material 22 protects the solar cell z1 from external impact, and is made of a transparent and light-resistant material so that sunlight can reach the solar cell 21. It is necessary to be formed. Therefore, as a specific material, for example, transparent acrylic resin or the like is desirable.

Further, in the illustrated example, this solar cell section 20 is provided in a recessed portion, but
It can also be provided so as to protrude from the center upper surface of the helmet 10. Furthermore, it can also be provided on the collar 12.

It is preferable that the heat sink 30 is made of a material with high thermoelectric conductivity, such as aluminum material, and the illustrated example shows a case in which the heat sink 30 is provided in a ring shape around a helmet 10. However, for example, it may be provided only in the front of the helmet 10. In other words, when the motorcycle runs, the helmet 10 receives wind from the front, so the portion that receives this wind, for example, the helmet 10, may be provided.
If it is installed on the front part of the helmet (or the side of the helmet),
Has a heat dissipation effect.

Although the thermoelectric element 40 in the illustrated example is provided in a ring shape, it can also be provided in a block shape.

Further, this thermoelectric element 40 can heat or cool the heat storage agent 50 using a changeover switch (not shown).

The heat transfer body 31 is made of a material with good thermal conductivity, such as aluminum material, and the heat transfer body 31 and the heat sink plate 30 are thermally connected at appropriate locations on the helmet 10.

The heat storage agent 50 may be solid, a liquid sealed in a bag, or even a sol that is intermediate between a solid and a liquid. Also, this heat storage agent 50 is for transmitting the temperature of one side of the thermoelectric element 40 to the inner surface of the helmet 10. Further, although the heat storage agent 50 is formed into a ring shape in the illustrated example, it can also be formed into a shape that extends over the entire interior of the helmet IO.

The inner body of the helmet 10 is made of a material that can ensure safety. Further, for convenience of drawing, wiring between the solar cell 21 and the thermoelectric element 40 is omitted.

Next, the actual use of the present invention will be explained using an example in which the inside of the helmet 10 is cooled.

First, set the changeover switch (not shown) to the cooling side.

After that, put on the helmet and go outside.

Then, the outdoor sun hits the solar cell section 20 of the helmet IO.

Then, sunlight hits the solar cell 21 through the protective material 22 of the solar cell section 20, so that a current flows from the solar cell 21.

The current from the solar cell 21 flows to the thermoelectric element 40, cools the heat storage agent 50 side of the thermoelectric element 40, and at the same time
The first side will be heated.

Then, the cooled heat storage agent 50 is cooled by energizing the thermoelectric element 40, and as a result, the inside of the helmet 10 is cooled.

At the same time, the heat transfer body 31 is heated, and this heat is transferred to the heat sink 30.
However, this heat is radiated from the heat sink 30.

In the helmet 10 according to the present invention, the solar cell 21 is used as a power source for energizing the thermoelectric element 40, so when the amount of light from the sun is large, that is, when it is hot during the day, the solar cell 21 is activated. Since the electric power becomes large, a large cooling effect is produced inside the helmet 10.

Therefore, if you leave the helmet 10 outdoors before riding a motorcycle, the sunlight will cause current to flow from the solar cell 21, which will activate the thermoelectric element 40 and cause the helmet to heat up.
This means that the inside of the IO is being cooled.

Also, when riding a motorcycle, please wear a helmet 10
Since the heat sink receives the wind, heat is efficiently radiated from the heat sink 30 by the wind.

Conversely, in order to heat the inside of the helmet 10 according to the present invention, the changeover switch is set to the heating side.

In addition, as in the case described above, the interior of the helmet 10 can be heated by exposing the solar cell 21 to sunlight.

Moreover, although the case where the heat radiating device is formed by only the heat radiating plate 30 has been described as an example, it is also possible to attach heat radiating fins to the heat radiating plate 30 or to attach a fan.

In the above description, the front part of the motorcycle helmet 10 is particularly missing, and the front part has a brim 12.
Although the explanation has been made using a type of helmet provided with a helmet as an example, in consideration of the heat inside the helmet 10 in summer, it is suitable to apply it to a so-called full-face type helmet 10.

Furthermore, if the present invention is applied to a helmet 10 used for other purposes, such as a helmet 10 used by construction workers, it is possible to work comfortably, especially during the hot summer months.

[Effects of the Invention] As explained above, although the present invention is a small device, there is no unpleasant vibration or noise, and furthermore, it can be cooled or heated simply by operating a switch, and it is particularly effective when provides a helmet that cools the inside in inverse proportion to the heat to prevent safety, reduce judgment when it's hot, and heat the helmet when it's cold.
