【Example】

 An embodiment of the present invention will be described in detail below with reference to the drawings. The drawing shows a helmet. In FIG. 1, the helmet 1 is a helmet body 2 made of a rigid material such as light alloy, laminated bakelite, polyester resin (reinforced plastic), polyethylene, etc., and a cushioning member for absorbing impact energy. 3 and a top ring 4 (a so-called string), a hammock portion 5, a headband 6, and a mounting means 8 having a string member 7 (a so-called jaw string), and has a withstand voltage property, a corrosion resistance property, a water resistance property, and a flame retardance property. It is configured to meet requirements such as sex.

In the above-described cap body 2, a plurality of positions, for example, two positions inside the cap body 2 corresponding to the positions of the acupuncture points of the occipital region (the acupuncture points of the human occipital region such as the upper celestial columns and the wind, the moxibustion point) are shown in FIG. Thermoelements 9 are arranged as shown in FIG.

As shown in FIG. 4, the thermoelement 9 includes Bi ₂ Te ₃ (an intermetallic compound of bismuth and tellurium) between a good conductor 10 on the heat generating side such as a Cu plate and a good conductor 11 on the heat absorbing side such as a Cu plate. Is a thermoelectric element configured by joining an n-type semiconductor 12 and a p-type semiconductor 13 such as. Although the thermoelement 9 is shown schematically in FIG. 4, a thermoelement 9 having a plurality of stages of pn junctions (for example, Thermomodule CP1.0-7-06L manufactured by Merco USA Inc., maximum current 3.0A, The maximum heat absorption is 1.4 W, the maximum voltage is 0.85 V, the maximum temperature difference is 67.0 ° C., and the weight is about 0.9 g).

A large number of metal wire wires are radially arranged as heat radiating means via an insulator (not shown) on the good heat-generating side conductor 10 of each of the above-mentioned thermo-elements 9, 9 so as to secure a large heat radiating area. The members 14 are connected to each other, and the heat dissipation members 14 are arranged outside the cap body 2 to improve heat dissipation. Note that, if necessary, the heat dissipation member 14 may be surrounded by a cover member 15 (see FIG. 1) having an opening 15a that covers the heat dissipation member 14 so as to dissipate heat.

On the other hand, a sponge member 16 having both a cooling air maintaining action and a cushioning action is provided inside the cap body 2 in correspondence with the above-mentioned arrangement portion of the thermoelements 9, 9. Is arranged substantially parallel to the lower surface opening 2a of the cap body 2.

By the way, as the DC power source (battery) for driving the thermoelement 9, a dry battery, a storage battery (rechargeable battery) or a solar battery which is directly attached to or separate from the cap 2 can be used. However, in this embodiment, a single type dry battery 17 having a rating of 1.5V is used, and this dry battery 17 is provided on the outer surface of the cap body 2 corresponding to the occipital region by a suitable means (a battery holder (not shown) is provided, and this battery holder is used as the cap body. It is firmly and replaceably attached to the outer surface of 2 by means such as adhesion or screwing.

Further, as shown in FIG. 4, the electrical connection configuration between the above-mentioned two thermoelements 9 and 9 and the dry battery 17 is such that these two thermoelements 9 and 9 are connected in parallel and the parallel circuit is formed. On the other hand, the positive electrode and the negative electrode of the dry battery 17 are connected to the battery via lines 18 and 19, respectively, and a current i is made to flow in the direction of the arrow in the figure. Here, the rating is 1. When one 5 V dry cell 17 is used, a voltage of 1.5 V × 1/2 is applied to each of the thermoelements 9 and 9 connected in parallel, so that the illustrated thermoelements 9 and 9 (available from Merco Corp., USA) are used. CP1.0-7-06L) rating and good conformity. Needless to say, an ON / OFF switch (not shown) may be provided on the line 18 or the line 19 as required. Further, when the battery is separately attached to the cap body 2, the circuit configuration may be configured as shown in FIG.

The illustrated embodiment is configured as described above, and the operation will be described below. When a DC power source for the dry battery 17 is applied to the thermoelements 9 and 9 described above, a current i flows in the direction indicated by the arrow in FIG. 4, and due to the Peltier effect, the heat absorbing side good conductor 11 of the thermoelements 9 and 9 absorbs heat. The heat is generated in the good conductor 10 on the heat generation side, and the heat on the heat generation side has a large heat dissipation area led to the outside of the cap body 2. The heat escapes from the heat dissipation member 14 to the outside. When the helmet 1 is worn, the portion of the user's occipital region corresponding to the acupoint position is favorably thermoelectrically cooled (same as electronic cooling), and the sponge member 16 maintains the cool air inside the hat body 2.

In summary, when the DC power of the battery (see the dry battery 17) is supplied to the thermoelement 9 arranged inside the cap body 2 of the helmet 1, the thermoelement 9 is thermoelectrically cooled on its heat absorbing side by the Peltier effect. Therefore, the inside of the cap body 2 can be cooled, and it is possible to effectively prevent the head of the user wearing the helmet 1 from being peeled off and to ensure comfort.

Further, since the heat on the heat generating side of the thermo element 9 can be released to the outside from the heat radiating means (see the heat radiating member 14) which is disposed outside the cap body 2, the cooling effect by the heat absorbing side of the thermo element 9 is improved. Therefore, there is an effect that it is possible to secure even better comfort.

Further, since the thermoelements 9 are arranged at a plurality of positions corresponding to the acupoint positions of the occipital region, cooling can be achieved from the portion corresponding to the acupoint positions, and the cooling effect by thermoelectric cooling is further enhanced. There is an effect that can be exerted.

In addition, a dry battery 17, a storage battery (a compact and rechargeable battery smaller than a dry battery such as Teckel / hydrogen storage battery) or a solar battery (a crystalline or amorphous silicon solar cell or compound) is provided outside the cap body 2. When a semiconductor solar cell or the like) is attached, there is an effect that the cap 2 and the DC power supply for driving the thermoelement can be integrated. On the other hand, if the battery for driving the thermoelement is provided at a position different from the cap body 2, there is an effect that the battery mounting structure for the cap body 2 can be omitted and the cap body 2 can be simplified.

Moreover, if the plurality of thermoelements 9, 9 connected in parallel are configured to be driven by the dry battery 17, cost reduction can be realized by the cost of the dry battery 17, and the plurality of thermoelements 9, 9 can be realized. Even if one of the nine fails, the other thermoelement 9 can cool the inside of the hat body 2.

When the battery polarity of the above-mentioned thermoelement 9 is reversed, heat absorption and heat generation are exchanged. Therefore, in the cold or the like, the thermoelement 9 should keep the inside of the cap body 2 warm. Is also possible.

In the correspondence between the configuration of the present invention and the above-described embodiment, the battery of the present invention corresponds to the single type dry battery 17 of the embodiment, and hereinafter, the heat dissipation means corresponds to the heat dissipation member 14. However, the present invention is not limited to the configuration of the above-described embodiment.

For example, the battery may be a size AA battery, a size AA battery, a rechargeable battery, or a solar battery. It can also be applied to MP type and mining hat type helmets having only chisel and helmets for motorcycles. The number of the thermoelements 9 may be two or more, and other heat radiating means such as heat radiating fins may be used instead of the heat radiating member 14 in which a large number of metal wire wires are radially arranged. Good. That is, the above-mentioned heat dissipation member may be formed of a single piece of aluminum plate, or may have a single or double structure or a multiple structure in which the aluminum plates are arranged in a meandering or wave arrangement.
