Description

The present invention relates to a jacket-type body cooling device for cooling the user's body by depriving the body of heat of vaporization (latent heat of vaporization) due to evaporation of perspiration emitted from the body of the user.

For those who wear bulletproof clothing, backpacks, and costumes, heat dissipation from the body is hindered, so they sweat and feel very uncomfortable, especially in the hot summer.

In view of this, Patent Literatures 1 and 2 propose a body cooling device that evaporates sweat from the body and cools the body with the heat of vaporization. This body cooling device consists of a flat bag-like mat formed by an upper cloth and a lower cloth, a fan attached to the upper cloth on the outside of the mat (on the side opposite to the body), and a power supply for supplying power to the fan. It has

The mat provided in the body cooling device has a spacer housed therein, and the spacer separates the upper cloth and the lower cloth by a predetermined distance to form an air flow path between them. .

By the way, there is a conventional body cooling device of a jacket type in which mats are arranged on the chest side and the back side of the user when worn, and the left and right upper ends of both mats are connected to each other.

Japanese Patent No. 5397828 Utility Model Registration No. 3207262

In a body cooling device, as described above, spacers are accommodated inside the mat, and these spacers form air flow paths between the upper cloth and the lower cloth. Met. Therefore, the mat itself is thin, and the space between the upper cloth and the lower cloth of the mat is narrowed, so that the area of the air flow passage formed in the mat becomes small, and a sufficient cooling effect can be obtained. There is no problem.

Also, the external force applied to the mat is received by the spacers accommodated inside the mat. However, if the thickness of the spacer is thin, the external force cannot be sufficiently received by the spacers, thus reducing the durability of the mat and the fan. There is also the problem of reduced properties and strength.

Furthermore, in a jacket-type body cooling device in which the upper ends of the front and rear mats arranged on the chest-abdominal side and the back side of the user are connected to each other when worn, cool air is discharged from the upper ends of the mats. There is also the problem that the cold air does not reach the user's neck area, and the user cannot be given a sufficient refreshing feeling because the cooling system does not adopt a structure that is designed to cool the user.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and its object is to increase the cooling effect by flowing a sufficient amount of air inside, and to improve the durability and strength of the jacket-type body cooling device. is to provide

The type body cooling device (1) is characterized in that the spacer (7) has a multi-stage structure in which a plurality of spacer pieces (7A) are stacked in the thickness direction of the mats (2F, 2B).

According to the present invention, since the spacer is constructed as a multi-layered structure and its thickness is increased, the flow area of the air flow path formed between the upper and lower cloths of each mat is increased. The flow rate of air flowing through the air flow passage is increased, promoting the evaporation of perspiration from the user. For this reason, more vaporization heat associated with the evaporation of sweat is removed from the user's body, effectively cooling the user's body.

In addition, since the external force applied to each mat is effectively received by the thickened spacers, it is possible to effectively prevent the mats and the fan from being damaged by the external force, thereby enhancing their durability.

Here, the lower cloth (2b) of each of the mats (2F, 2B) is composed of a highly breathable and moisture-permeable mesh cloth, and the upper end thereof You can extend it to the central part. Alternatively, an air discharge portion (2b1) for discharging the air in the air flow passage (8) to the outside may be provided in the widthwise central portion of the upper end surface of each of the mats (2F, 2B).

According to the above configuration, part of the cool air flowing upward through the air circulation passage of each mat is discharged from the position of the upper end surface of the mat of the lower cloth toward the user's neck. The surroundings are effectively cooled, and the user can feel even more refreshing.

Also, the air inlet (10a) of the fan (9) may be covered with a detachable mesh cap (14).

FIG. 7 is a schematic perspective view of the mat of the jacket type body cooling device.

The mat 2F is formed by sewing the upper cloth 2a located on the opposite side of the chest and abdomen of the user and the lower cloth 2b located on the side of the chest and abdomen of the user in the wearing state, thereby forming a flat, approximately rectangular shape in front view. As shown in FIG. 1, belt-shaped side cloths 2c having a predetermined width are sewn on the left and right sides of the mat 2F, respectively, so that the mat 2F has a predetermined thickness. there is

Here, for the upper cloth 2a and the side cloth 2c of the mat 2F, a material that does not allow air to pass through, such as a cloth woven from plastic fibers such as polyester cloth or nylon cloth, or a high-density cloth obtained by weaving threads at a high density. A density cloth or the like is used. As shown in FIG. 4, the lower cloth 2b uses a mesh cloth having high air permeability and moisture permeability. It extends to the center of the upper end surface in the width direction (the portion between the left and right bands 3L and 3R). Thus, an outflow port 2b1, which is an air outlet, is formed in the center of the upper end surface of the mat 2F in the width direction.

By the way, as shown in FIG. 5, a spacer 7 is accommodated inside the mat 2F. The spacer 7 maintains a predetermined distance between the upper cloth 2a and the lower cloth 2b. An air circulation passage 8 is formed between the lower cloth 2b.

Further, as shown in FIG. 3, a fan 9 is attached at a position slightly above the center in the vertical direction in the center in the width direction of the upper cloth 2a. The fan 9 incorporates an electric motor housed in a portion of a cylindrical case 10 facing the air circulation passage 8 (electric motor integrated type). A rechargeable battery 12 as a power source is electrically connected via 11 . A switch 13 is connected in the middle of the power cord 11 .

When the switch 13 is turned on and power is supplied from the battery 12 to the fan 9, the fan 9 rotates, and the rotation of the fan 9 causes air (outside air) to flow from the circular suction port 10a of the case 10 to the air flow passage 8. and aspirated. A fine mesh cap 14 shown in FIG. 1 may be detachably attached to the suction port 10a and the suction port 10a may be covered with the cap 14 if necessary.

As shown in FIG. 6, the spacer 7 has a four-layer structure in which four spacer pieces 7A are stacked in the thickness direction of the mat 2F (horizontal direction in FIG. 6). Here, the configuration of each spacer piece 7A will be described below with reference to FIGS. 7 and 8. FIG.

FIG. 8 is a front view of a spacer piece, and FIG. 9 is a partial perspective view of the same spacer piece. and a flexible connection portion 7a2 for connecting them. The convex portion 7a includes a frame-shaped portion 7a1, four column portions 7a3 whose one end is connected to the frame-shaped portion 7a1 and stands up from the frame-shaped portion 7a1, and the other ends of these four column portions 7a3. and a rectangular connection standing portion 7a4 that connects the .

The spacer piece 7A configured as described above is integrally formed by injection molding of a resin such as polyethylene or polypropylene. The above-described structure of the spacer piece 7A is merely an example, and various other structures can be adopted. can be done.

In this embodiment, as described above (see FIG. 6), the spacer 7 has a four-layer structure in which the spacer pieces 7A shown in FIGS. 8 and 9 are stacked in four stages in the thickness direction of the mat 2F. The spacer 7 widens the space between the upper cloth 2a and the lower cloth 2b of the mat 2F, and also widens the width (flow area) of the air flow passage 8 formed in the mat 2F. In this embodiment, the four spacer pieces 7A are stacked in four stages to form a four-layer structure, but the number of stages in which the spacer pieces 7A are stacked is arbitrary.

The jacket-type body cooling device 1 constructed as described above is worn by the user as shown in FIG. 2 as described above. The cooling action in will be described.

When the user wearing the jacket-type body cooling device 1 turns on the switch 13, power is supplied from the battery 12 to the fan (electric motor) 9 through the power cord 11 as described above, and the fan 9 operates at a predetermined speed. rotationally driven. When the fan 9 is driven to rotate in this way, air (outside air) is sucked into the mat 2F from the suction port 10a opening in the upper cloth 2a, and this air (outside air) is absorbed by the air circulation formed inside the mat 2F. It flows upward through the channel 8 .

On the other hand, the perspiration emitted from the chest and abdomen of the user evaporates and is taken into the air circulation passage 8 through the moisture-permeable lower cloth 2b, together with the air (outside air) flowing upward through the air circulation passage 8. It is ejected outside the mat 2F. When the sweat evaporates, heat of vaporization (latent heat of vaporization) is removed from the user's body, thereby cooling the user's body (chest and abdomen). Here, in the present embodiment, since the spacer 7 is configured as a four-layer structure and its thickness is increased, the flow of the air flow path 8 formed between the upper cloth 2a and the lower cloth 2b of the mat 2F is reduced. The passage area is increased, the flow rate of air (outside air) flowing through the air flow passage 8 is increased, and the evaporation of perspiration from the user is promoted. For this reason, more vaporization heat associated with the evaporation of sweat is removed from the user's body, effectively cooling the user's body.

In addition, in this embodiment, since the lower cloth 2b made of mesh cloth is extended to the widthwise central portion (the portion between the left and right bands 3L and 3R) of the upper end surface of the mat 2F, cold air is blown from this portion to the user. It erupts around the neck. Therefore, the user's neck is also cooled by the cool air, and the user can feel even more refreshed.

Further, since the external force applied to the mat 2F is effectively received by the thick spacer 7, even if a strong external force acts on the mat 2F and the fan 9, they can be prevented from being damaged. It is also possible to obtain the effect that the durability of the is enhanced.

Furthermore, if necessary, the suction port 10a of the fan 9 can be covered with a detachable mesh cap 14 to prevent foreign matter from being sucked into the suction port 10a. 9 is prevented from being damaged, air is stably introduced into the air circulation passage 8 by the fan 9, and the user's body is stably cooled by the jacket-type body cooling device 1.

The jacket-type body-cooling device 1 configured as described above secures appropriate thickness and strength to the spacers 7 by adopting a lamination structure in which the spacer pieces 7A are stacked in a plurality of stages. Therefore, it is suitable for use as a bulletproof vest (plate carrier) used in survival games. In this case, by attaching the mesh cap 14 to the inlet 10a of the fan 9, it is possible to prevent bullets for survival games from entering the inside of the fan 9. can be avoided.

As described above, the jacket-type body cooling device 1 having the above-described structure secures a sufficient flow of air in the air flow passage 8 by adopting a laminated structure in which the spacer pieces 7A are stacked in multiple stages. The user's body can be sufficiently cooled by the mat 2F, and the air outlet 2b1 is formed in the center of the upper end surface of the mat 2F in the width direction, so that cool air is sent around the user's neck during use. It is possible to give a suitable refreshing feeling to the person. Therefore, when wearing a costume such as a doll or an animal, it is also possible to use this jacket-type body cooling device 1 by wearing it under the costume. As a result, the body of the user wearing the costume can be effectively cooled, and the user can feel refreshed.

Although the cooling action of the front mat 2F arranged on the chest and abdomen side of the user has been described above, the cooling action of the rear mat 2B arranged on the back side of the user is also performed in the same manner. The back side of the user is similarly cooled by removing the heat of vaporization (latent heat of vaporization) from the user's body when the sweat emitted from the back of the user evaporates. In addition, the rear mat 2B also has the same effects as described above.

As is clear from the above description, according to the present invention, a sufficient amount of air is allowed to flow inside the jacket-type body-cooling device 1 to enhance the cooling effect, and the durability and strength of the jacket-type body-cooling device 1 are improved. can be improved.

The application of the present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the technical ideas described in the scope of claims, the specification, and the drawings.
