Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a head cooling system in which a head heat radiation unit is attached to a head mounted body such as a hat such as a helmet, a cap, a hat, and a visor to cool a human head. Regarding the device.

[0002]

2. Description of the Related Art A cooling hat, in which a hat and a Peltier element are combined to cool the forehead of a person who wears the hat, has been disclosed by the applicant of the present invention.
It is known in Japanese Patent Laid-Open Publication No. 60-94609.

[0003] In these cooling hats, a cooling plate is provided at a portion of the hat which comes into contact with the forehead of the person wearing the hat, a Peltier element is disposed on the surface thereof, and a heat sink is further mounted on the surface. It has a configuration.

According to such a cooling cap, since the back surface of the Peltier element is cooled, the cooling plate in contact therewith becomes cold, and the front part in contact with the cooling plate feels cold.
If you wear this cooling hat, you can feel the coolness even in the suburbs. Therefore, this cooling hat is claimed to provide a comfortable feeling to those who play golf and other sports.

Although the cooling cap has certain advantages, there are many points that still have to be improved in order to put it into practical use, and no improvement has been made to put it into practical use. It has not been realized.

This means that the surface of the Peltier element in contact with the cooling plate becomes cold, while the surface of the Peltier element in contact with the heat dissipation plate becomes hot. However, on the heated Peltier element surface,
The radiator plate made of aluminum or the like is simply attached, heat is quickly saturated, and sufficient heat cannot be released, and the cooling plate surface in contact with the Peltier element cannot be cooled sufficiently. It is not possible to expect comfortable coolness that the person wearing the hat feels cool enough.

Another reason is that the Peltier element is expensive, so that the cooling cap is also expensive, and that it is not possible to expect sufficient comfort in view of the price, it is necessary to put the cooling cap into practical use. It was hindering me.

In order to solve these drawbacks, the inventor of the present invention previously proposed in a patent application [title of invention: hat equipped with a cooling radiator fan] filed on July 7, 1994, a cap, a hat, The cooling plate is attached to the hat so as to face the front head of the person wearing the hat such as a visor, and the collar provided on the front surface of the hat is provided with a through hole. An axial fan motor was provided on the front surface, and a ventilation passage part such as a slit was formed to dissipate heat by the air sent by the axial fan motor through the through hole and blow it toward the back surface of the collar. A heat sink having a cooling radiator portion, and the cooling radiator portion facing the through hole and attached to the back surface portion of the collar is provided, and formed on the front surface portion of the cooling plate and the rear portion of the cooling radiator portion. A Peltier element is installed between the rear end faces of the heat storage unit. It has proposed a hat with a cooling radiator fan.

According to the cooling cap of the prior invention, when a switch (not shown) of the power supply battery is turned on, the axial fan motor rotates and blows air to the cooling radiator portion of the heat sink through the through hole formed in the collar of the cap. To do.

The blown air is sent to the front of the face portion of the person wearing the hat [hat wearing person] through the draft passage portion of the cooling radiator, and at the same time, the heat stored in the heat storage portion. Since the heat is dissipated, the heat generated on the front surface of the Peltier element can be sufficiently dissipated and the back surface of the Peltier element can be efficiently cooled, so that the cooling plate can be sufficiently cooled, and as a result, comfortable cool air can be obtained. Can be applied to a section.

Since the Peltier element is powered on (not shown), the Peltier element cools the cooling plate.
Since the cooling plate is cooled by the Peltier element, the front part of the head facing the back surface (front surface facing the front part) of the cooling plate is cooled, and a sufficiently comfortable cold air is felt.

The improved cooling cap of the invention of the prior application has practically sufficient characteristics and is near the stage of practical use. However, this cooling cap has a structure in which a hole must be formed in the surface of the cooling cap. Therefore, in the case of a hat, such as a helmet, in which the surface of the hat is not perforated by safety standards, it cannot be constructed as a cooling hat.

Therefore, the present inventor has previously disclosed a further improved cooling cap.

This has a heat radiator having a cooling radiator part having a flow passage part such as a slit formed in the thickness direction in the front part and a heat storage part in the rear part, and air blown to the above-mentioned flow passage part to blow air below it. Axial fan motor attached to the upper surface of the heat sink to allow heat to flow, and a hat such as a helmet, cap, hat, visor, etc., attached via a Peltier element on the rear end surface of the heat storage section. A cooling device unit for a cooling cap provided with a cooling plate attached so as to be located at a position facing the front head of the wearer, and the cooling device unit for a cooling cap, the upper surface portion of the axial fan motor and the above A cooling hat such as a helmet equipped with a cooling device unit for a cooling hat, which is fixed to the lower portion of the hat collar by forming an appropriate gap between the upper and lower surfaces of the hat collar, is provided.

According to such a cooling cap, the forehead can be sufficiently cooled, and a cooling cap more suitable for practical use can be obtained.

[0016]

However, the cooling cap as described above is
Even though the cooling effect is sufficient, a large and heavy heat sink and axial fan motor must be provided to dissipate the heat from the Peltier element, and the cooling mechanism occupies a very large area and is heavy. Since it becomes a hat, it cannot be constructed as a lightweight head cooling device, has little versatility, and has limited applications. Also, as a matter of course, there is a drawback that the price becomes expensive. Therefore, there is a drawback that the type, shape, design, etc. of the cooling hat to be applied are greatly restricted.

According to the present invention, even if the head cooling mechanism is mounted on the head mounting body such as a helmet, a cap, a hat, a visor, etc., the structure is very simple, easy to assemble, light in weight and inexpensive in price. It is an object to obtain a head cooling device which can be applied to various head mounted bodies and is excellent in shape and design.

[0018]

SUMMARY OF THE INVENTION The object of the present invention is as follows.
The head cooling plate 2 is arranged on one surface of the Peltier element 1, and the head heat dissipation guide plate 3 is arranged on the other surface, and the heat transferred to the head heat dissipation guide plate is radiated to the outside. For absorbing water, at least the outer surface of which is made of a material having a vaporizing function 4
A head heat radiating unit 5 having a helmet, a cap, with the head cooling plate surface side facing the front head surface.
This can be achieved by providing a head cooling device provided on the head mounted body 6 such as a hat or a visor.

Further, in the above head cooling device, it is possible to make the water absorbing material 4 more useful by using a material containing an aromatic material.

{Action} The head cooling device 7 may be constructed in any shape such as a helmet, a cap, a hat, and a visor, but in the embodiment, the head mounting band is taken into consideration in consideration of light weight and equipment. It has a structure. Therefore, the head-mounted body 6 is a head-mounted band. Therefore, in the following, it will be referred to as the head mounting band 6.

With reference to FIGS. 1 to 4, the head cooling plate 2 is opposed to the front head of a person (not shown), and the head mounting band 6 is tightened to an appropriate tightening size. The head mounting device 7 is mounted on the head. The power supply box 8 attached to the head mounting band 6 has a built-in power supply battery 9. Normally, when the power supply battery 9 is used, the power supply changeover switch 10 provided in the battery box 8 is closed on the contact 11 side. Is made. Therefore, when the power switch 12 provided in the power box 8 is closed at the contact 13 side which is the power ON side, the Peltier element 1
Is energized.

As is well known, the Peltier element 1 is based on the principle of the Peltier effect, and when one surface is cooled when energized, the other surface becomes hot. Here, the Peltier element 1 is arranged so that the surface on the side of the head cooling plate 2 is cooled when energized.
One surface is cooled, and the cool air is transmitted to the head cooling plate 2 to cool the front head of a person (not shown) in contact with the head cooling plate 2.

On the other hand, when one surface of the Peltier element 1 is cooled, the other surface of the Peltier element 1 becomes hot. If this heat is not radiated by any means, the Peltier element 1 will be saturated, and one side of the Peltier element 1 will become hot,
Can not be cooled. Since the head heat dissipation guide plate 3 is provided on the other surface of the Peltier device 1, the heat of the other surface of the Peltier device 1 is guided to the head heat dissipation guide plate 3.

Although the heat of the other surface of the Peltier element 1 cannot be sufficiently radiated to the outside only by providing the head heat dissipation guide plate 3, the head heat dissipation guide plate 3 has an outer surface to dissipate the heat of the head heat dissipation guide plate 3. Moisture absorbent 4 having at least an outer surface formed of a material having a vaporizing function for radiating heat transmitted to the guide plate to the outside
Is arranged. Although a proper amount of moisture is absorbed into the moisture absorbing material 4, the moisture absorbing material 4 is not formed of a material that can simply absorb moisture, and the head heat dissipation guide plate 3 does not have to be formed. The transferred heat is positively absorbed by the water in the water absorbing material 4, and the heat is radiated to the outside by its vaporizing action, so that the head heat dissipation guide plate 3, the Peltier element 1, and the head cooling plate 2 are saturated. There is nothing to do. Therefore, by closing the power switch 12 on the contact 13 side,
Even if a large heat sink or an axial fan motor is not used, the Peltier device 1 can efficiently cool the human forehead through the head cooling plate 2.

FIG. 1 is an external perspective view of a head cooling device 7 as a first embodiment of the present invention, and FIG. 2 is a head mounting band (head mounting member 6) of the head cooling device 7. ) Is a top view with a part removed, FIG. 3 is an exploded perspective view of the head heat dissipation unit 5, and FIG. 4 is a circuit diagram. Hereinafter, a head cooling device 7 as a first embodiment of the present invention will be described with reference to FIGS. 1 to 4.

The head heat radiating unit 5 will be described. When it comes into contact with a human head,
The head cooling plate 2 is arranged on the front head contact surface with a material having a good thermal conductivity, such as aluminum, which is slightly curved when viewed from above so as to match the shape. For this reason, from the outer surface (the other surface) in order, a head heat dissipation guide plate 3 formed of a material having good heat conductivity such as aluminum, a Peltier element storage holding plate 14 formed of plastic or the like, a rubber sponge, etc. Peltier element storage / holding plate 15 formed of a relatively soft material
Further, the head cooling plate 2 is screwed into the through holes 16 formed therein, and screwed into the screw holes 18 formed in the head heat dissipation guide plate 3.

As the Peltier element storage plates 14 and 15, those having the thickness of the Peltier element 1 when the two plates 14 and 15 are superposed are selected.
A notch 19 and a through hole 20 each having a shape capable of accommodating the Peltier element 1 are formed at positions facing each other.

Therefore, as described above, the head heat dissipation guide plate 3 and the Peltier element storage holding plates 14 and 15 are provided by the screws 18.
Further, when the head cooling plate 2 is overlapped and fixed, the Peltier element 1 is previously housed in the notch 19 and the through hole 20. In this case, grease having good thermal conductivity is applied to both surfaces of the Peltier element 1 in advance.
The heat generated on the other surface of the Peltier element 1 is guided to the head heat dissipation guide plate 3 to facilitate the heat dissipation, and the cold temperature generated on the one surface of the Peltier element 1 is easily guided to the head cooling plate 2. .

The Peltier element storage / holding plate 14 is formed to be longer than the head heat dissipation guide plate 3, the Peltier element storage / holding plate 15 and the head cooling plate 2 in the lateral direction, and the head is provided at the end thereof. Through hole 21 for attaching the part mounting band 6,
The slit hole 22 is formed. One end of the mounting band 6 is sandwiched by the other end of the battery box support plate 25 at one end of the Peltier device housing / holding plate 14, and is fixed by a fixing member such as a screw 23. 24 is a nut. Reference numeral 26 is a through hole for fixing the mounting band formed at the other end of the battery box support plate 25.

The one end of the mounting band 6 is passed through the slit hole 22 formed at the other end of the Peltier element storage / holding plate 14 and fixed by the fixing member 27 so that the Peltier device storage / holding plate 14 is mounted on both ends. The band 6 is formed in a loop shape. By using the elastic band that is formed of a stretchable rubber band, the head mounting device 7 can be easily mounted on the head of a person even when the size of the head of the person is different.

The one end of the battery box support plate 25 is
The screw 28 is passed through a through hole 33 formed therein and a through hole (not shown) formed in the mounting band 6, and is fixed to the mounting band 6 by screwing and fixing together with the nut 29.

A power supply box 8 containing a power supply battery 9 (not shown) is fixed to the surface of the battery box support plate 25, and a power supply switch 12 is exposed on the upper surface of the power supply box 8. The Peltier device 1, the power source battery 9 and the power source switch 12 are connected as shown in the circuit diagram of FIG.
Is switched to the contact 13 side so that the Peltier element 1 is energized. Also, the power source changeover switch 10
Is normally closed to the contact 11 side to use the power supply battery 9. By switching the changeover switch 10 to the jack side contact 28 (not shown) formed in the power supply box 8, the external DC power supply 29 can be selected.

On the outer surface of the head heat dissipation guide plate 3, at least an outer surface portion for radiating the head heat transmitted to the head heat dissipation guide plate 3 to the outside has a vaporizing function of felt or sponge. A sheet-shaped water absorbent material 4 formed of such a material is attached by an appropriate means. In this case, the water absorbing material 4 having a property of simply absorbing water cannot sufficiently radiate the head heat transmitted to the head heat dissipation guide plate 3, and at least the outer surface portion. Must be formed of a material having a vaporizing function.

For example, as one of the most suitable types of the water absorbing material 4, the inner surface absorbs water drops adhering to glass parts such as windows and bay windows, wash pipes, etc., and the outer surface absorbs air temperature. It is preferable to use a commercially available water removing tape that can evaporate the absorbed water when the temperature rises. For example, one such water removal tape is from Konishi Co., Ltd., which has a thickness of about 4 mm.
The outer surface layer is a special diffusion layer, the inner side is a special adsorption layer, and the inner side is formed with an adhesive layer for easy attachment.

The head heat dissipating unit 5 is used to protect the sheet-shaped water absorbent material 4 and to embed the fragrance material.
On the front surface of the moisture absorbing material 4, a moisture absorbing material protecting and fragrance storage cassette 30 made of plastic is fixed by an appropriate means. A plurality of through holes 31 are formed in the surface portion of the moisture absorbing material protecting and aromatic agent storing cassette 30, and water or the like can be contained in the moisture absorbing material 4 through the through holes 31. A fine resin net 32 is attached to the inner surfaces of the through holes 31 in consideration of the design surface.

FIG. 5 shows a partial view of another head radiating unit 5 ', which has a Peltier element Che element having the same thickness as the Peltier element 1 instead of using the Peltier element accommodating and holding plates 14 and 15. This is completed by using one storage holding plate 14 '. Since there is no particular difference from the case of the first embodiment, detailed description thereof will be omitted.

Referring to FIG. 6 and FIG. 7, the structure is the first.
Although there is almost no difference from the case of the embodiment, since some dead space is formed between the water absorbent 4 of the storage cassette 30 and the cassette 30, the fragrance material or the fragrance material is formed in this space portion. An example is shown in which the fragrance material 34 soaked by means such as coating is embedded in the cassette 30. When the fragrance material 34 has a granular shape, the fragrance material spills out from the through holes 31. Therefore, the through holes 31 in the portions without the resin nets 32 are closed, or the inner surface thereof is covered with the resin nets 32.
It is necessary to keep closed at.

[0038]

According to the present invention, it is possible to cool the head sufficiently without using a fan motor, a large heat sink, etc., so that it is light and does not burden the fan even when it is mounted on the head. Since no noise is generated by the motor, no harsh noise is generated, the location can be selected anywhere, and the small size and light weight make it possible to diversify the selection of head-mounted body types and diversify the design. Therefore, a very practical head cooling device can be constructed inexpensively and easily.
