Description

Technical Field

[0001] The present invention relates to a cooling device and a cooling device unit that can be worn on the body via clothing or equipment, or alone.

Background Art

[0002] Conventionally, a cooling device that is worn on equipment or the like and cools the wearer's body has been proposed. For example, according to Patent Document 1, a cooling device for protective clothing is a cooling device for protective clothing that is worn under the protective clothing and cools the wearer's body. It includes a spacer for securing an air flow path through which air circulates, an upper cloth provided so as to cover the surface of the spacer on the side in contact with the protective clothing and having low air leakage, and a lower cloth provided so as to cover the surface of the spacer on the side in contact with the wearer's body and having low air leakage and moisture permeability. It has a flat mat, an opening formed at one end of the mat, a blowing means attached to a predetermined part of the part of the mat not covered by the protective clothing when the wearer wears the protective clothing, and a power supply means for supplying power to the blowing means. The cooling device for protective clothing is configured such that a fan as the blowing means is driven, and outside air is taken into the air flow path through the fan. Then, the taken-in air circulates upward in the air flow path and is discharged to the outside from the opening when it reaches the opening.

[0003] According to this, by attaching the blowing means to a predetermined part of the part of the mat not covered by the protective clothing when the wearer wears the protective clothing, this blowing means can take in outside air into the air flow path or discharge the air flowing through the air flow path to the outside without being obstructed by the protective clothing. Therefore, when the blowing means is driven to circulate outside air in the air flow path, the sweat emitted from the body of the wearer wearing the protective clothing evaporates, is taken into the air flow path through the moisture-permeable lower cloth, and is discharged to the outside. And it is described that the body of the wearer can be cooled by utilizing the fact that the heat of vaporization is taken away from the body of the wearer during the evaporation of sweat.

[0004] [Patent Document 1] Japanese Patent Publication No. 2010-91163 [Overview of the project] [Problems that the invention aims to solve]

[0005] However, conventional designs have the following problems. In protective clothing cooling devices, a fan is driven to draw outside air into an air passage via the fan. This drawn-in air then circulates upward within the air passage and, upon reaching an opening, is discharged to the outside through that opening.

[0006] In protective clothing cooling devices, air circulates between the upper and lower layers of fabric, meaning the lower layer is sandwiched between the body and the garment. This can obstruct airflow, causing sweat to remain on the skin and underwear, making it difficult to cool the air through evaporative cooling. In this case, the protective clothing cooling device may not be able to effectively cool the body.

[0007] The object of the present invention is to provide a cooling device and a cooling device unit that cool the wearer's body by bringing circulating air into direct contact with it. [Means for solving the problem]

[0008] A cooling device according to a first aspect of the present invention is a cooling device used when worn with clothing or attached to a body with exposed skin, comprising a device body formed to extend in the longitudinal direction, a fan, and a power supply device for supplying power to the fan, wherein the device body comprises a first air circulation path extending in the longitudinal direction, the first air circulation path is cylindrical or rectangular in shape, and a longitudinal opening is formed in a part of its circumference that is continuously open along the longitudinal direction, the first opening is provided at a first end which is one end in the longitudinal direction, or at a position adjacent to the first end, and the first connection port is provided at a second end which is the other end in the longitudinal direction, or at a position adjacent to the second end, the fan is connected to the first air circulation path at the first connection port, the fan is attached to the body with the longitudinal opening facing the body, and when the fan is operated, air flows through the longitudinal opening in the first air circulation path in direct contact with the body.

[0009] According to this, when the cooling device is mounted with its longitudinal opening facing the body and the fan is activated, air flows through the first airflow path facing the body, directly contacting the body. When the body sweats, the air flowing directly in contact with the body promotes the generation of heat of vaporization, making the body easier to cool.

[0010] Furthermore, when the cooling device is attached to the body and the longitudinal opening comes into contact with the body, the first air circulation path is surrounded by the body, and when the fan operates so that air flows from the first opening toward the first connection port, negative pressure is generated in the first air circulation path, and the longitudinal opening may be attracted to the body.

[0011] In this case, when air flows from the first opening towards the first connection port in the first air circulation path, negative pressure is generated, and the longitudinal opening is attracted to the body. Therefore, the first air circulation path is surrounded, preventing the intrusion of outside air, and the difference in flow velocity across the entire longitudinal opening is reduced, resulting in a greater cooling effect on the body and the circulating air.

[0012] Furthermore, the main body of the cooling device is provided with a second air circulation path extending along the longitudinal direction, the second air circulation path is formed in a cylindrical or rectangular shape, has a second connection port at one end, the third end, and a second opening at the other end, the fourth end, the fan is connected to the second air circulation path at the second connection port, and when the fan is operated so that air flows from the first opening toward the first connection port, the air drawn in from the first connection port is discharged from the second connection port, and air may flow through the second air circulation path toward the second connection port.

[0013] In this case, when the cooling device operates so that the fan draws in air from the first connection port and discharges it from the second connection port, air flows through the second air circulation path from the second connection port toward the second opening. The cooling device can discharge the air cooled in the first air circulation path through the second air circulation path and toward the second opening without directly discharging it from the fan. This allows the cooling device to discharge air from the second opening in a predetermined direction and / or position.

[0014] Furthermore, the cooling device may be configured such that the direction of air flow in the first air circulation path is different from the direction of air flow in the second air circulation path.

[0015] In this case, since the direction of air flow in the first air circulation path and the direction of air flow in the second air circulation path are different, the position and / or direction of the second opening can be arbitrarily formed relative to the position of the first opening. The air cooled in the first air circulation path can be discharged towards a predetermined part of the body for cooling.

[0016] Furthermore, the second air circulation path of the cooling device may be formed to overlap the first air circulation path on the side opposite to the body to which it is attached.

[0017] In this case, the second airflow path is formed to overlap the first airflow path on the side opposite to the body to which it is attached. Therefore, in the planar direction in the longitudinal and width directions, the increase in planar area can be suppressed in the area where the second airflow path overlaps with the first airflow path.

[0018] Furthermore, the second air circulation path of the cooling device may be bendable and / or expandable and / or rotatable in the width direction, with the side of the second opening being perpendicular to the longitudinal direction, starting from the side of the second connection port, and the position or direction of the second opening may be changed.

[0019] In this case, since the cooling device can change the position or direction of the second opening, the direction of the outlet can be set to face a desired position or direction on the body.

[0020] Furthermore, the second air circulation path of the cooling device may be formed in parallel with the first air circulation path in the width direction, which is perpendicular to the longitudinal direction.

[0021] In this case, since the cooling device has a second air circulation path formed in parallel with the first air circulation path, the second air circulation path can be formed within the height range of the first air circulation path.

[0022] Furthermore, the cooling device comprises a water storage tank, a pump, and a water supply channel, wherein the water supply channel is located in the first air circulation path, or faces the first air circulation path and is capable of spraying water from a water spraying section formed in the water supply channel toward the interior of the first air circulation path.

[0023] In this case, the cooling device can spray water into the first airflow path, thereby hydrating the body when worn and increasing the cooling effect through evaporative cooling. Furthermore, if the water is sprayed towards the inside of the first airflow path, water scattering is suppressed, thus reducing water consumption.

[0024] Further, the cooling device includes a water storage tank, a pump, and a water supply path. The water supply path is arranged in the first air circulation path and can spray water from a water spraying portion formed in the water supply path toward the inside of the first air circulation path. In the first air circulation path, the water supply path is arranged to protrude from a wall surface portion forming the first air circulation path. When worn on the body, the water spraying portion opens toward the body side. When the fan operates, due to the negative pressure generated in the first air circulation path, the water spraying portion closest to the first connection port may contact the body.

[0025] In this case, due to the negative pressure generated in the first air circulation path of the cooling device, the water sprayed by the water spraying portion closest to the first opening contacting the body is likely to penetrate. Therefore, the air flowing in the first air circulation path and the body are easily cooled by the heat of vaporization. Furthermore, since the sprayed water is likely to penetrate the body, dripping of water from the water spraying portion or leakage from the first air circulation path can be suppressed.

[0026] Further, the cooling device includes a water storage tank, a pump, and a water supply path. The water supply path may be arranged in the second air circulation path or face the second air circulation path and can spray water from a water spraying portion formed in the water supply path toward the inside of the second air circulation path.

[0027] In this case, since the cooling device can spray water in the second air circulation path, the air cooled in the first air circulation path can be further cooled by the heat of vaporization and discharged from the second opening.

[0028] Further, the cooling device unit according to the second aspect of the present invention includes the cooling device and a fixture for attaching the cooling device and wearing it on the body. The fixture includes a hanging portion. When worn on the body, one side is the head side and the other side is the leg side in the worn state. The hanging portion has the cooling device attached thereto, and the leg side has a free end starting from the head side.

[0029] According to this, the cooling device unit has a hanging section to which one of the cooling devices is attached, with the head side as the starting point and the leg side as the free end. This allows the cooling device to conform to the shape of the body and make contact with recessed areas, thereby enhancing the cooling effect.

[0030] Furthermore, the cooling device unit comprises the cooling device and an orthotic device to which the cooling device is attached and worn on the body, and the second opening of the cooling device attached to the orthotic device may be positioned so that the discharged air is directed toward the neck and / or armpit of the body.

[0031] In this case, the cooling unit is positioned so that the second opening faces the neck and / or armpits of the body, allowing cooled air to be discharged in a position that is effective in lowering the user's body temperature. [Brief explanation of the drawing]

[0033] The cooling device 1 and cooling device unit 30 embodying the present invention will be described below with reference to the drawings. The embodiments for carrying out the invention and the referenced drawings are used to illustrate the technical features that the present invention may adopt. The present invention is not limited to these. The configurations shown in the drawings are not intended to limit the invention to these configurations, but are merely illustrative examples.

[0034] <<Contents common to all embodiments>> A cooling device 1 according to a first aspect of the present invention will now be described. First, a configuration common to each embodiment of the cooling device 1 will be described. The cooling device 1 is used by being attached to a body 50 that is either wearing clothes or has exposed skin. As shown in Figure 1, etc., the cooling device 1 comprises a device body 2 that extends in the longitudinal direction, a fan 3, and a power supply device 25 that supplies power to the fan 3. The body 50 described below includes both a state in which clothes are worn and a state in which the skin is exposed.

[0035] As shown in Figure 1, the direction perpendicular to the longitudinal direction is defined as the width direction. As shown in Figure 2, the direction perpendicular to both the longitudinal and width directions is defined as the height direction. Assuming the cooling device 1 is attached to the body 50, in the longitudinal direction, one side is the head side and the other side is the leg side. In the height direction, the side attached to the body 50 is the body side, and the opposite side is the outside. The outside in the height direction is the side to which the orthotic device 31, described later, is attached.

[0036] <Explanation of the overall structure> Next, the overall configuration of the cooling device 1 will be described. As shown in Figures 1 to 7, the device body 2 is provided with a first air circulation path 4 extending in the longitudinal direction. The first air circulation path 4 is cylindrical or rectangular, and a longitudinal opening 10 is formed in a part of its circumference that is continuously open along the longitudinal direction. The first air circulation path 4 has a first opening 5 at one end in the longitudinal direction, which is a first end 41, or adjacent to the first end 41, and a first connection port 6 at the other end in the longitudinal direction, which is a second end 42, or adjacent to the second end 42. The cylindrical shape of the first air circulation path 4 includes an elliptical shape, and also includes the case where the cross-sectional shape is a curved shape less than a semicircle due to the longitudinal opening 10. In addition, the rectangular shape includes polygonal shapes such as triangular and pentagonal shapes, as well as square shapes.

[0037] As shown in Figure 2, the fan 3 is connected to the first air circulation path 4 at the first connection port 6. The cooling device 1 is attached to the body 50 with its longitudinal opening 10 facing the body 50, and when the fan 3 is activated, air flows through the first air circulation path 4 in direct contact with the body 50.

[0038] As shown in Figures 2 and 4 as examples, the first air circulation path 4 is a rectangular tube extending in the longitudinal direction, with a longitudinal opening 10 formed in a part of its periphery. For example, the first air circulation path 4 is formed by a wall portion 7 which is a sheet-like first top portion 7a that extends in the width direction which is perpendicular to the longitudinal direction, and a plurality of first rib portions 8 that are formed along the direction in which the first top portion 7a extends and project in a direction intersecting the first top portion 7a. In the example shown in Figure 4, etc., the first air circulation path 4 is surrounded on three of its four sides by the first top portion 7a and the two first rib portions 8, and the other side facing the first top portion 7a is open as a longitudinal opening 10. The longitudinal opening 10 may be entirely open on the side facing the body 50, as shown in Figures 4, 5, and 6(a), or only a part of the side facing the body 50 may be open, as shown in Figure 6(b).

[0039] Figures 4 and 5 show an example in which the first top surface portion 7a, which is the wall portion 7, is formed in a flat plate shape. However, as shown in Figure 6(a), the wall portion 7 may have a curved first top surface portion 7b, or it may have other cross-sectional shapes. Also, Figures 4 and 5 show an example in which the first rib portion 8 is formed in a plate shape. However, the cross-sectional shape may be triangular, curved, or other. Alternatively, as shown in Figure 6(a), the curved first top surface portion 7b and the first rib portion 8 may be continuously connected and integrally formed, for example, with a semicircular cross-sectional shape. The same applies to the second top surface portion 13a, the second top surface portion 13b, and the second rib portion 14 in the second air circulation path 9, which will be described later.

[0040] In the examples shown in Figures 4 to 6, the first top surface portion 7a or the first top surface portion 7b and the first rib portion 8 may be formed as a single unit, or they may be separate parts joined together to form a single unit. It is desirable that the first top surface portion 7a, the first top surface portion 7b, and the first rib portion 8 all be made of a material with high airtightness. Furthermore, they may also be made of a material that has hygroscopic properties. Examples of materials for the first top surface portion 7a and the first top surface portion 7b include thin rubber sheets or resin sheets with a certain degree of rigidity. Examples of materials for the first rib portion 8 include closed-cell sponge, rubber, and expanded polystyrene, but it may also be made of the same material as the first top surface portion 7a or the first top surface portion 7b. For example, the thickness of the first top surface portion 7a and the first top surface portion 7b is 3 mm, and the thickness of the first rib portion 8 is 5 mm.

[0041] The fan 3 connected to the power supply 25 is connected to the first air circulation path 4 at the first connection port 6. As illustrated in Figure 4, the cooling device 1 is attached to the body 50 with the tip of the first rib portion 8 that forms the longitudinal opening 10 facing the body 50. When the fan 3 is operated, air flows through the first air circulation path 4, directly contacting the body 50 at the longitudinal opening 10. Here, the direction of air flow in the first air circulation path 4 can be either from the first opening 5 to the first connection port 6, as shown by the arrows in Figure 23, or from the first connection port 6 to the first opening 5.

[0042] Furthermore, as shown in Figure 2, etc., the fan 3 can be operated to draw in air from the first connection port 6 and discharge it from the second connection port 11. The cooling device 1 is attached to the body 50, and when the longitudinal opening 10 comes into contact with the body 50, the first air circulation path 4 is surrounded by the body 50. In the example shown in Figure 4, etc., the first air circulation path 4 is surrounded by the first top surface portion 7a, the multiple first rib portions 8, and the body 50. When the fan 3 operates to allow air to flow from the first opening 5 towards the first connection port 6, negative pressure is generated in the first air circulation path 4, and the longitudinal opening 10 is attracted to the body 50. Negative pressure is generated for the following reasons: When the fan 3 acts and outside air is drawn in from the first opening 5, the airflow velocity increases, and the dynamic pressure in the first air circulation path 4 increases. As a result, the static pressure of the cooling device 1 in the first embodiment decreases, and negative pressure is generated. The higher the air intake capacity of the fan 3, the higher the negative pressure in the first air circulation path 4. The principle behind the generation of negative pressure is based on Bernoulli's theorem.

[0043] In the examples shown in Figures 2 and 4, when the longitudinal opening 10 is in contact with the body 50, the tip of the first rib portion 8 is in contact with or attracted to the body 50. In the example shown in Figure 6(a), the tip of the curved first top surface portion 7b is in contact with or attracted to the body 50. Here, "attracted" does not only refer to a state in which the longitudinal opening 10 and the body 50 are completely fixed together, but also includes the degree to which the cooling device 1 is attracted to the body 50. Even if the cooling device 1 attached to the body 50 falls due to its own gravity, if the cooling device 1 is attracted to the body 50, it is included in the concept of attraction. Furthermore, if only the first rib portion 8, or both the first top surface portion 7a and the first rib portion 8, are made of a flexible material, the first air circulation path 4 can follow the curvature of the surface of the body 50, thereby reducing the gap between the first rib portion 8 and the body 50.

[0044] When the longitudinal opening 10 is attracted to the body 50, the first air circulation path 4 becomes enclosed, and the flow velocity of the circulating air becomes constant. In addition, it becomes difficult for air to enter the first air circulation path 4 from the outside. As the output of the fan 3 increases, the negative pressure generated in the first air circulation path 4 increases, making it easier for the longitudinal opening 10 to be attracted to the body 50.

[0045] As shown in Figures 1 to 23, the first air circulation path 4 is formed in a straight line in the longitudinal direction. When the fan 3 is operated, air flows in a straight line from the first opening 5 to the first connection port 6. This reduces the resistance to air flow caused by the operation of the fan 3.

[0046] <Explanation of the water supply channel 23 in the first air circulation path 4> Next, the water supply channel 23 will be described. As shown in Figure 1, the cooling device 1 comprises a water storage tank 21, a pump 22, and a water supply channel 23. As shown in Figures 4 and 6, the water supply channel 23 is located in the first air circulation path 4, or as shown in Figure 5, it faces the first air circulation path 4. The cooling device 1 can spray water from a water spray section 24 formed in the water supply channel 23 into the interior of the first air circulation path 4. As an example, as shown in Figure 1, the second end 42 of the device body 2 is equipped with a water storage tank 21, a pump 22, and a power supply unit 25. The water supply channel 23 is connected to the water storage tank 21 and supplied with water by the pump 22. The power supply unit 25 is electrically connected to the fan 3 and the pump 22. As will be described later, the water storage tank 21, the pump 22, and the power supply unit 25 may be configured separately from the cooling device 1. Alternatively, the pump 22 of the cooling device 1 may not be connected to the power supply unit 25 and may be operated manually.

[0047] Furthermore, as shown in Figures 4, 6, and 19, in the first air circulation path 4, the cooling device 1 has a water supply channel 23 that protrudes from the wall surface 7, and when attached to the body 50, the water spraying section 24 opens toward the body 50. As shown in Figure 4, when the fan 3 is operated, the negative pressure generated in the first air circulation path 4 causes the water spraying section 24 closest to the first opening 5 to come into contact with the body 50. Note that the water spraying section 24 may come into contact with the body 50 at other points as well as the point closest to the first opening 5.

[0048] More specifically, as shown in Figure 4, the water supply channel 23 is fixed to the body side of the first top surface 7a. The water supply channel 23 may be fixed by adhesive, welding, or by tying it to the first top surface 7a with fastening thread or the like. For example, a silicone tube is used for the water supply channel 23, and the watering section 24 is a perforated portion.

[0049] For example, as shown in Figure 4(a), the outer diameter of the water supply channel 23 may be smaller than the height of the first rib section 8 in the height direction. In this case, when the fan 3 is activated, negative pressure is generated in the first air circulation path 4 by the circulating air, and the first rib section 8 is attracted to the body 50. Furthermore, the first top surface section 7a bends toward the body 50 in a valley shape, causing the water supply channel 23 and the water spray section 24 to move and come into contact with the body 50.

[0050] Furthermore, as shown in Figure 4(b) as an example, there are cases where the outer diameter of the water supply channel 23 is greater than the height of the first rib section 8 in the height direction. In this case, when the fan 3 is activated, negative pressure is generated in the first air circulation path 4 by the circulating air, and the water supply channel 23 and the water spray section 24 come into contact with the body 50 together with the first top surface section 7a. In addition, the first top surface section 7a bends in a mountain shape on the opposite side from the case in Figure 4(a), and the first rib section 8 is attracted to the body 50. In either example, when the fan 3 is activated, the water spray section 24 of the water supply channel 23 comes into contact with the body 50.

[0051] Tap water is preferable as the medium for spraying water through the water supply channel 23. However, other liquid media may be used depending on the application. In the description of the cooling device 1, an example in which the water supply channel 23 is provided in the first air circulation path 4 is described, but it is not necessarily required. That is, if the user's body 50 is sweating, the cooling effect is achieved by the heat of vaporization of the sweat, so there is no need to spray water.

[0052] Next, we will describe examples of how to use the cooling device 1. Here, we will describe an example of attaching the cooling device 1 to the body 50 as a standalone unit. An example of attaching the cooling device 1 to the orthosis 31 and then attaching it to the body 50 will be described later. As shown in Figure 24, the cooling device 1 can be attached to the body 50 using the auxiliary device 32. In the example shown in Figure 24(a), the string-shaped auxiliary device 32a is attached to each of the two first rib portions 8, and the cooling device 1 is attached to the body 50 by being worn around the neck and along the back. In the example shown in Figure 24(b), a band-shaped auxiliary device 32b made of a material that can be attached to the hook-and-loop fastener 33, or a band-shaped auxiliary device 32b with the hook-and-loop fastener 33 attached, is joined to the hook-and-loop fastener 33 of the cooling device 1, and then wrapped around the back to the chest or abdomen and secured. Of course, in either case, it is also possible to attach the cooling device 1 to the abdominal side.

[0053] Furthermore, the cooling device 1 can also be used by inserting it into a pocket or other part of the clothing worn by the user. Alternatively, the user may use the cooling device 1 by holding it in their hand and positioning it along their body 50. In either case, the longitudinal opening 10 of the cooling device 1 should face the body 50, with the first opening 5 facing the head and the fan 3 facing the legs. The reason for positioning the fan 3 towards the legs is that keeping the fan 3 away from the ears reduces the level of noise.

[0054] <<Effects common to all embodiments>> <Effects of the overall structure> The overall configuration common to the cooling device 1 described above provides the following effects. As shown in Figure 23, when the fan 3 is operated with the cooling device 1 mounted so that the longitudinal opening 10 faces the body 50, air flows through the longitudinal opening 10 of the first air circulation path 4 facing the body 50, directly contacting the surface of the body 50. When the body 50 sweats, the generation of heat of vaporization is promoted by the air flowing directly in contact with the body 50, making it easier to cool the body 50.

[0055] If the first air circulation path 4 is covered, the air will not come into direct contact with the body 50, thus reducing its cooling effect. In contrast, the cooling device 1 allows air to circulate while directly contacting the surface of the body 50, resulting in a greater cooling effect. Furthermore, it has the advantage of requiring a smaller airflow volume when the wind speed is kept constant.

[0056] As shown in Figure 23, in the first air circulation path 4, whether the air circulation direction is from the first opening 5 to the first connection port 6 or from the first connection port 6 to the first opening 5 due to the operation of the fan 3, the circulating air comes into direct contact with the body 50, thus having a cooling effect on the body 50. It is desirable that the longitudinal opening 10 and the body 50 come into contact along the entire length of the body when the cooling device 1 is attached to the body 50. However, even if there is a gap between the longitudinal opening 10 and the body 50, the air circulating in the first air circulation path 4 comes into direct contact with the body 50, thus having a cooling effect on the body 50.

[0057] Furthermore, as shown in Figure 2, when air flows from the first opening 5 to the first connection port 6 in the first air circulation path 4 of the cooling device 1, negative pressure is generated and the longitudinal opening 10 is attracted to the body 50. In the example shown in Figure 2, the tip of the first rib portion 8 that forms the longitudinal opening 10 comes into contact with the body 50. Therefore, the first air circulation path 4 is surrounded, preventing the intrusion of outside air, and the difference in flow velocity across the entire longitudinal opening 10 is reduced, resulting in a greater cooling effect on the body 50 and the circulating air. Note that as the output of the fan 3 increases, the negative pressure increases, and the longitudinal opening 10 and the body 50 become more closely in contact.

[0058] As illustrated in Figure 4, when the first rib portion 8 that forms the longitudinal opening 10 is attracted to the body 50, the first air circulation path 4 becomes a circulation path surrounded by the first top surface portion 7a, the first rib portion 8, and the body 50 that the first rib portion 8 is in contact with. The air in the longitudinal opening 10 of the first air circulation path 4 circulates in a state in which the intrusion of outside air is suppressed, while in direct contact with the body 50, whether wearing clothes or with exposed skin. Therefore, when the body 50 sweats, the generation of heat of vaporization is further promoted by the circulation of air in the first air circulation path 4, resulting in a cooling effect on the air and the body 50.

[0059] If the user is wearing clothes, and the first rib portion 8 comes into contact with or adheres to the user's body 50, the clothes will adhere closely to the user's skin, and sweat produced on the skin will penetrate the clothes. The sweat that has penetrated the clothes will come into contact with the air circulating in the longitudinal opening 10 of the first air circulation path 4. This will promote the generation of evaporative cooling in the clothes, and the cooling effect on the user's skin, which is in close contact with the clothes, will increase.

[0060] Furthermore, when the longitudinal opening 10 of the first air circulation path 4 adheres to the body 50, the clothing worn becomes tightly attached to the body 50, making it easier for the clothing to absorb sweat, etc. This makes it easier for evaporative cooling to occur due to the sweat, etc. absorbed by the clothing. Therefore, the cooling effect of the air circulating in the first air circulation path 4 and the body 50 is enhanced.

[0061] Furthermore, if the user attaches the cooling device 1 to an exposed area of ​​their body 50, the sweat produced on the skin will come into direct contact with the air circulating in the longitudinal opening 10 of the first air circulation path 4, thereby enhancing the cooling effect.

[0062] Furthermore, when fan 3 is operating, air flows in a straight line from the first opening 5 to the first connection port 6. Therefore, resistance to airflow is reduced, making it possible to miniaturize fan 3 or reduce its output.

[0063] Furthermore, when the first rib portion 8 adheres to the body 50 and the area around the first air circulation path 4 is sealed, the flow velocity of the circulating air becomes constant. Therefore, the generation of evaporative heat due to sweating from the body 50 is uniformly promoted inside the first air circulation path 4.

[0064] Furthermore, since the first air circulation path 4 is less susceptible to air intrusion from the outside, the output of the fan 3 can be reduced.

[0065] <Effects of the water supply channel 23 in the first air circulation path 4> Furthermore, the cooling device 1, by being equipped with a water supply channel 23, provides the following effects. As shown in Figures 2 to 6, the cooling device 1 can spray water into the first air circulation path 4, thereby providing moisture to the body 50 when worn and increasing the cooling effect due to evaporative cooling. In addition, if the cooling device 1 sprays water from the water supply channel 23 into the interior of the first air circulation path 4, water scattering is suppressed, thus reducing water consumption. The cooling device 1 can exert a cooling effect due to evaporative cooling even if the body 50 is not sweating.

[0066] When the fan 3 is activated, negative pressure is generated in the first air circulation path 4 by the circulating air, and the area is surrounded by the body 50 with which the longitudinal opening 10 is in contact. In the example shown in Figure 4, etc., it is surrounded by the first top surface 7a, the first rib portion 8, and the body 50 with which the first rib portion 8 is in contact. Therefore, water sprayed from the water supply channel 23 into the interior of the first air circulation path 4 is prevented from scattering outside the path. Alternatively, water is prevented from leaking out of the first air circulation path 4.

[0067] Furthermore, the cooling device 1 is designed so that the water spraying section 24, which is closest to the first opening 5, comes into contact with the body 50 due to the negative pressure generated in the first air circulation path 4, allowing the sprayed water to easily penetrate. Therefore, the air circulating in the first air circulation path 4 and the body 50, which is in contact with the longitudinal opening 10, are easily cooled by the heat of vaporization due to the sprayed water. Moreover, since the sprayed water easily penetrates the body 50, dripping from the water spraying section 24 or leakage from the first air circulation path 4 can be suppressed.

[0068] As shown in Figures 2 and 3, when the cooling device 1 is attached to the body 50 such that the first opening 5 is on the head side and the fan 3 is on the leg side, the water spraying section 24, which is closest to the first connection port 6, is positioned at the lowest point as shown in the figures.

[0069] Figure 4 shows a cross-section of the sprinkler unit 24 closest to the first connection port 6. The water sprinkled from the sprinkler unit 24 tends to hang downwards due to gravity. At this time, the lowest sprinkler unit 24 comes into contact with the body 50, so the sprinkled water permeates the body 50. Therefore, the hanging of the sprinkled water due to gravity is suppressed. Even if water were to drip down from another sprinkler unit 24 along the water supply channel 23, the sprinkler unit 24 closest to the first connection port 6 would come into contact with the body 50, blocking the water from hanging down and preventing water from leaking to the outside.

[0070] <<Contents common to cooling devices 1a of the first embodiment to cooling device 1e of the fifth embodiment>> Next, we will describe the features common to the cooling device 1a of the first embodiment to the cooling device 1e of the fifth embodiment. As shown in Figure 2, the main body 2 of the cooling device 1 is provided with a second air circulation path 9 that extends along the longitudinal direction. As shown in Figures 4 to 6, the second air circulation path 9 is formed in a cylindrical or rectangular shape. The second air circulation path 9 has a second connection port 11 at one end, the third end 91, and a second opening 12 at the other end, the fourth end 92.

[0071] Fan 3 is connected to the second air circulation path 9 at the second connection port 11. When fan 3 operates to circulate air from the first opening 5 towards the first connection port 6, the air drawn in from the first connection port 6 is discharged from the second connection port 11, and air circulates in the second air circulation path 9 from the second connection port 11 towards the second opening 12.

[0072] Furthermore, as shown in Figure 2 and other figures, the cooling device 1 has different airflow directions in the first airflow path 4 and the second airflow path 9. Different airflow directions mean that, for example, as shown in Figure 2, if the airflow direction in the first airflow path 4 is from the head side to the leg side, the airflow direction in the second airflow path 9 will bend approximately 360 degrees from the leg side to the head side. Alternatively, as shown in Figures 9 to 13 described later, the airflow direction in the second airflow path 9 will be in an oblique direction in the width direction. Furthermore, this includes cases where the airflow direction in the second airflow path 9 is in any direction, such as bending approximately 90 degrees relative to the airflow direction in the first airflow path 4 and heading in the width direction.

[0073] Next, the water supply channel 23 common to the cooling device 1a of the first embodiment to the cooling device 1e of the fifth embodiment will be described. As shown in Figure 1, the cooling device 1 includes a water storage tank 21, a pump 22, and a water supply channel 23. As shown in Figures 4 and 19, the water supply channel 23 is located in the second air circulation path 9, or faces the second air circulation path 9, and water can be sprayed into the second air circulation path 9 from a water spraying section 24 formed in the water supply channel 23. In the following descriptions of the cooling device 1 of each embodiment, the case in which the water supply channel 23 is provided in the second air circulation path 9 will be described, but it is not necessarily required.

[0074] <<Effects common to cooling devices 1a of the first embodiment to cooling device 1e of the fifth embodiment>> The cooling devices 1a of the first embodiment to 1e of the fifth embodiment, as described above, share a common configuration that provides the following effects. As shown in Figure 2, etc., when the fan 3 is activated, the cooling device 1 draws in air from the first connection port 6 and discharges it from the second connection port 11, and air flows through the second air circulation path 9 from the second connection port 11 toward the second opening 12. The cooling device 1 can discharge the air cooled by the heat of vaporization in the first air circulation path 4 through the second air circulation path 9 and toward the second opening 12 without directly discharging it from the fan 3. As a result, the cooling device 1 can discharge air from the second opening 12 toward a predetermined direction and / or position.

[0075] If the second air circulation path 9 is not formed, and the air cooled by evaporative cooling in the first air circulation path 4 is directly discharged from the fan 3, the cooled air will be dispersed during discharge, which may reduce the cooling effect on the user. In contrast, the second opening 12 of the cooling device 1 can concentrate and discharge air within a certain area.

[0076] Alternatively, the exhaust port of fan 3 is generally limited to one direction of exhaust, and it may not be possible to discharge air in the desired direction. In that case, the air may not be discharged to the part that the user wants to cool, and the cooling effect may be reduced. In contrast, cooling device 1 is equipped with a second air circulation path 9, which forms a second opening 12 at a different location from the exhaust port of fan 3, allowing air to be discharged to the desired location or direction.

[0077] Furthermore, as shown in Figure 2, the cooling device 1 has different airflow directions in the first airflow path 4 and the second airflow path 9. Therefore, the cooling device 1 can arbitrarily form the position and / or direction of the second opening 12 relative to the position of the first opening 5. If the airflow direction in the first airflow path 4 and the airflow direction in the second airflow path 9 were the same, once the position of the first opening 5 is set, the second opening 12 would be formed at the other end of the first opening 5 in the longitudinal direction. The direction in which the second opening 12 is set is uniquely determined, and the degree of freedom of position is small. In contrast, the cooling device 1 has a high degree of freedom regarding the position and / or direction in which the second opening 12 is formed relative to the position of the first opening 5. That is, the cooling device 1 can cool the body 50 by discharging the air cooled in the first airflow path 4 toward a predetermined part of the body 50.

[0078] Furthermore, as shown in Figures 2 and 4, the cooling device 1 can spray water into the second air circulation path 9, thereby further cooling the air cooled in the first air circulation path 4 by the heat of vaporization and discharging it from the second opening 12.

[0079] <Contents of the cooling device 1a of the first embodiment> Next, with reference to Figures 1 to 9, the specific details of the cooling device 1a of the first embodiment will be described. Common details already described will be omitted. Any of the forms described in the common details section can be adopted for the first air circulation path 4. The same applies to the other embodiments described below. The cooling device 1a includes a second air circulation path 9 in the device body 2a. This will be described with reference to Figures 1, 4, and 5. The second air circulation path 9 is formed by a second top surface portion 13a, which is a wall surface portion 13 extending along the longitudinal direction and widening in the width direction, and a plurality of second rib portions 14 projecting in a direction intersecting the second top surface portion 13a. It is formed to overlap the first air circulation path 4 on the side opposite to the body 50 to which it is attached. More specifically, as shown in Figure 1, in the planar direction along the longitudinal and width directions, the second air circulation path 9 is formed within the range where the first air circulation path 4 is formed, except near the fourth end portion 92 where the second opening 12 is formed. As another example, as shown in Figure 6(a), the second air circulation path 9 may be formed in a cylindrical shape with a part of its periphery open, similar to the first air circulation path 4, and the curved second top surface 13b, which is the wall surface 13, may be connected to the first top surface 7b, which is the wall surface 7 of the first air circulation path 4.

[0080] In the examples shown in Figures 4 and 5, the second air circulation path 9 is formed by being surrounded on all four sides by a second top surface 13a, two second rib sections 14, and a first top surface 7a. Although not shown, the second air circulation path 9 may also have a first bottom surface 15 on the side opposite the second top surface 13a. Furthermore, in the cooling device 1b of the second embodiment and the cooling device 1c of the third embodiment, which will be described later, the second air circulation path 9 is surrounded on all four sides by a second top surface 13a, two second rib sections 14, and a first bottom surface 15.

[0081] As shown in Figure 2, the fan 3 is mounted on the first top surface 7a and protrudes outward in the height direction. The intake port of the fan 3 opens toward the body side and is connected to the first connection port 6. The exhaust port of the fan 3 opens toward the head side in the longitudinal direction and is connected to the second connection port 11.

[0082] As shown in Figure 2, when the cooling device 1a is attached to the body 50 and the fan 3 is activated, air flows in the direction of the arrow. That is, air is drawn in from the first opening 5, passes through the first air flow path 4, and reaches the first connection port 6. Furthermore, the direction of air flow is changed by approximately 360 degrees via the fan 3, and is discharged from the second opening 12 through the second air flow path 9. The second opening 12 is located closer to the head than the first opening 5 in the longitudinal direction. This is to prevent the air discharged from the second opening 12 from being directly drawn in from the first opening 5. The same applies to the cooling devices 1b of the second embodiment to the cooling device 1e of the fifth embodiment, which will be described later.

[0083] The dimensions of the cooling device 1a are, for example, 200 mm in length, 60 mm in width, and 20-25 mm in height. The dimensions of the cooling device 1a can be changed depending on the intended use, the user's height, etc.

[0084] The first opening 5 in the first air circulation path 4 will be described with reference to Figures 7 and 8. In the first example shown in Figure 7(a), the first opening 5 opens at the first end 41 on the longitudinal head side, similar to Figure 3. The first opening 5 opens at the same widthwise spacing as the two first rib portions 8 in which the first air circulation path 4 is formed. In the second example shown in Figures 7(b) and 8(a), the first opening 5 opens on both sides in the widthwise direction at the leg side of the wall portion 41a formed at the first end 41 of the first air circulation path 4. In the third example shown in Figures 7(c) and 8(b), the first opening 5 is formed by opening a part of the wall portion 41a formed at the first end 41 of the first air circulation path 4.

[0085] Next, the water supply channel 23 in the first air circulation path 4 will be described. As shown in Figure 3, the water supply channel 23 connected to the pump 22 is installed along the widthwise side surface of the first rib portion 8 and passes through the first opening 5 into the interior of the first air circulation path 4. As shown in Figures 3 and 4, the water supply channel 23 is arranged along the widthwise centerline C1 of the first air circulation path 4 and extends to a position close to the first connection port 6. As shown in Figures 2 and 3, water spraying sections 24 are formed in the water supply channel 23 at approximately equal intervals. Note that the water supply channel 23 has a similar configuration in the examples shown in Figures 6(a) and 6(b).

[0086] Next, the water supply channel 23 in the second air circulation path 9 will be described. As shown in Figures 1 and 2, the water supply channel 23 connected to the pump 22 is attached to the widthwise side of the second rib section 14 and passes through the second opening 12 into the interior of the second air circulation path 9. As shown in Figures 1 and 4, the water supply channel 23 is arranged along the widthwise centerline C2 of the second air circulation path 9 and extends to a position close to the second connection port 11. As shown in Figures 1 and 2, sprinkler sections 24 are formed in the water supply channel 23 at approximately equal intervals. Note that the water supply channel 23 has a similar configuration in the examples shown in Figures 6(a) and 6(b).

[0087] Next, another example of the water supply channel 23 in the first air circulation path 4 will be described. As shown in Figure 5(a), the water supply channel 23 is arranged along the widthwise centerline C1 of the first air circulation path 4, passes through the first opening 5 into the interior of the first top surface 7a, and extends to a position close to the first connection port 6. In yet another example, as shown in Figure 5(b), the water supply channel 23 is arranged along the heightwise centerline C3 of the first air circulation path 4, passes through the first opening 5 into the interior of the first rib portion 8, and extends to a position close to the first connection port 6. In all examples, the water supply channel 23 and the water spraying section 24 face the first air circulation path 4. Note that even when the perimeter of the first air circulation path 4 is formed by a curved first top surface 7b, as shown in Figure 6(a), the water supply channel 23 can have a similar configuration. The same applies to the example shown in Figure 6(b).

[0088] Next, another example of the water supply channel 23 in the second air circulation path 9 will be described. As shown in Figure 5(a), the water supply channel 23 is arranged along the widthwise centerline C2 of the second air circulation path 9, passes through the second opening 12 into the interior of the second top surface 13a, and extends to a position close to the second connection port 11. In yet another example, as shown in Figure 5(b), the water supply channel 23 is arranged along the heightwise centerline C4 of the second air circulation path 9, passes through the second opening 12 into the interior of the second rib portion 14, and extends to a position close to the second connection port 11. In all examples, the water supply channel 23 and the watering section 24 face the second air circulation path 9. Note that even when the periphery of the second air circulation path 9 is formed by a curved second top surface 13b, as shown in Figure 6(a), the water supply channel 23 can have a similar configuration. The same applies to the example shown in Figure 6(b).

[0089] The example described with reference to Figure 5 illustrates a case in which a water supply channel 23, formed from a silicone tube, is embedded in the first top surface 7a, the second top surface 13a, the first rib portion 8, or the second rib portion 14. As another example, the water supply channel 23 may be formed by integrally creating a cylindrical shape inside each of the first top surface 7a, the second top surface 13a, the first rib portion 8, or the second rib portion 14 without using components such as a silicone tube.

[0090] Next, with reference to Figure 9, another example of the cooling device 1a of the first embodiment will be described. The cooling device 1a described with reference to Figures 1 to 6 shows an example in which the second air circulation path 9 is formed to overlap the first air circulation path 4 in the height direction, and the second opening 12 in the second air circulation path 9 is formed to protrude more than the first opening 5 in the first air circulation path 4 in the longitudinal direction. In contrast, another example can be adopted.

[0091] Figure 9(a) shows an example where the second air circulation path 9 is formed diagonally to the longitudinal direction, and the second opening 12 is formed inclined to the left in the width direction shown in the figure. Figure 9(b) shows an example where the second air circulation path 9 is formed to be shorter than the first air circulation path 4 in the longitudinal direction, and the second opening 12 is located closer to the leg than the first opening 5. Figure 9(c) shows an example where the second air circulation path 9 is formed in the width direction. Figure 9(d) shows an example where the second air circulation path 9 is inclined in the width direction, and the second opening 12 faces the leg side. In addition, the second air circulation path 9 can be formed to face various directions depending on the intended use, or the mounting position and state on the body 50.

[0092] <Effects of the cooling device 1a of the first embodiment> The cooling device 1a described above provides the following effects. As shown in Figure 2, etc., the cooling device 1a is formed such that the second air circulation path 9 overlaps the first air circulation path 4 on the side opposite to the body 50 to which it is attached. Therefore, in the planar direction in the longitudinal and width directions, the increase in the planar area due to the second air circulation path 9 can be suppressed in the area where the second air circulation path 9 overlaps with the first air circulation path 4. In other words, the cooling device 1a can suppress the increase in planar area due to the formation of the second air circulation path 9. In the examples of the cooling device 1a shown in Figures 1 to 8, the second air circulation path 9 is formed within the planar range in which the first air circulation path 4 is formed, except for the vicinity of the fourth end 92 where the second opening 12 is formed. In the case shown in Figure 9(b), the second air circulation path 9 can be formed within the planar range of the first air circulation path 4. Also, in the examples shown in Figures 9(a), (c), and (d), in the planar direction, the increase in planar area is suppressed in the portion of the second air circulation path 9 that overlaps with the first air circulation path 4, and only the portion that extends beyond the first air circulation path increases the planar area.

[0093] Furthermore, in the example shown in Figure 2, the direction of air flow in the first air circulation path 4 and the direction of air flow in the second air circulation path 9 differ by approximately 360 degrees. As shown in Figure 24, etc., when the cooling device 1a is attached to the body 50 and the first opening 5 is positioned on the head side, the first connection port 6 is on the leg side and the second opening 12 is positioned on the head side. In this case, as shown in Figures 27 and 28 described later, the cooled air is discharged from the second opening 12 toward the user's neck 52. That is, the cooled air can be discharged toward the neck 52, which is effective in lowering the user's body temperature.

[0094] Furthermore, as shown in Figure 2, since the second opening 12 is located closer to the head than the first opening 5 in the longitudinal direction, it is possible to prevent the air discharged from the second opening 12 from being directly drawn in from the first opening 5. As a result, the air discharged from the second opening 12 can be efficiently sent to the neck 52, increasing the cooling effect. The same applies to the cooling devices 1b of the second embodiment to the cooling device 1e of the fifth embodiment, which will be described later.

[0095] Furthermore, in the examples shown in Figures 4, 5(a), and 6, the water supply channel 23 extends along the centerline C1 in the first air circulation path 4, allowing water to be sprayed evenly in the width direction. That is, when the longitudinal opening 10 of the cooling device 1a is installed in contact with the body 50, water can be sprayed over the entire space where the first air circulation path 4 is formed. Therefore, the cooling device 1a can cool the air in the first air circulation path 4 by further promoting the generation of heat of vaporization.

[0096] Furthermore, in the examples shown in Figures 4, 5(a), and 6, the water supply channel 23 extends along the center line C2 in the second air circulation path 9, allowing water to be sprayed throughout the entire internal space of the second air circulation path 9. Therefore, the cooling device 1a can further promote the generation of heat of vaporization and cool the air in the second air circulation path 9.

[0097] Furthermore, in the example shown in Figure 5, the water supply channel 23 is formed inside the first top surface portion 7a or the first rib portion 8 in the first air circulation path 4, so it does not obstruct air circulation. Moreover, the size of the first air circulation path 4 can be reduced compared to the example shown in Figure 4. The same applies to the second air circulation path 9, where the water supply channel 23 is formed inside the second top surface portion 13a or the second rib portion 14, so it does not obstruct air circulation. Moreover, the size of the second air circulation path 9 can be reduced compared to the example shown in Figure 4.

[0098] Furthermore, in the example shown in Figure 2, the total length of the air circulation path is the sum of the lengths of the first air circulation path 4 and the second air circulation path 9. If the air circulation direction of the first air circulation path 4 and the second air circulation path 9 were the same, the longitudinal length of the air circulation path in the cooling device 1 would be approximately twice as long. In contrast, in the cooling device 1 shown in Figure 2, the second air circulation path 9 is formed in a direction that folds back relative to the first air circulation path 4, so the longitudinal length can be shortened.

[0099] The same applies to the alternative example shown in Figure 9. As shown in Figures 9(a), (c), and (d), even when the second air circulation path 9 extends beyond the planar area where the first air circulation path 4 is formed, the longitudinal length can be shortened compared to the case where the air in the first air circulation path 4 and the second air circulation path 9 flows in the same direction.

[0100] <Contents of cooling devices 1b of the second embodiment to cooling device 1d of the fourth embodiment> Next, referring to Figures 10 to 14, the common features of the cooling device 1b of the second embodiment to the cooling device 1d of the fourth embodiment will be described. The first air circulation path 4 from cooling device 1b to cooling device 1d can adopt any form described in the common features section for all embodiments. The device body 2b of cooling device 1b to the device body 2d of cooling device 1d is provided with a second air circulation path 9. The second air circulation path 9 is formed by a rectangular tubular shape, extending along the longitudinal direction and widening in the width direction, surrounded by a second top surface portion 13a, a plurality of second rib portions 14 protruding in a direction intersecting the second top surface portion 13a, and a first bottom surface portion 15 facing the second top surface portion 13a. For example, there are two second rib portions 14. Although not shown, the second air circulation path 9 may be formed in a cylindrical shape.

[0101] The second air circulation path 9 from cooling device 1b to cooling device 1d is bendable and / or expandable and / or rotatable in the width direction, with the side of the second connection port 11 being perpendicular to the longitudinal direction, and the position or direction of the second opening 12 can be changed.

[0102] The water supply channel 23 is the same as that of the cooling device 1a in the first embodiment. The configuration described with reference to Figures 2 to 6 is possible and produces the same effects.

[0103] <Effects of cooling devices 1b in the second embodiment to cooling device 1d in the fourth embodiment> The cooling devices 1b of the second embodiment to 1d of the fourth embodiment described above provide the following effects. As shown in Figures 10 to 14, the position or direction of the second opening 12 can be changed in the cooling devices 1b to 1d, so that the direction of the exhaust port can be set toward a desired position or direction on the body 50. That is, the cooling device 1b can be adjusted by changing the position or direction of the air discharge while it is attached to the body 50. Alternatively, even if there are restrictions on the mounting position or mounting direction when attaching the cooling device 1b to the body 50, the position or direction of the air discharge can be adjusted by changing it.

[0104] <Configuration of the cooling device 1b in the second embodiment> Next, with reference to Figures 10 and 11, the configuration specific to the cooling device 1b of the second embodiment will be described. The second air circulation path 9 of the cooling device 1b is rotatable in the width direction perpendicular to the longitudinal direction, starting from the side of the second connection port 11, and the direction of the second opening 12 can be changed. The second air circulation path 9 is equipped with a rotating cover 17 on the side of the second connection port 11. As shown by the dashed line in Figure 10, the rotating cover 17 is rotatable about a rotation center C5 around a rotation pivot shaft 18 formed in the device body 2c. The second air circulation path 9 is rotatable integrally with the rotating cover 17. The rotating cover 17 also serves as a path connecting the exhaust port of the fan 3 and the second connection port 11 of the second air circulation path 9. The rotation pivot shaft 18 is formed in a ring shape to cover the fan 3, and a flow passage 20 is formed in the range in which the air passage 19, formed by cutting out a part of the rotating cover 17, rotates. In the example shown in Figure 10, the second air circulation path 9 can rotate by an angle r on one side around the rotation center C5. That is, it can rotate by an angle r to the left and right in the width direction as shown in Figure 10 with respect to the longitudinal direction. The other configurations are the same as those of the cooling device 1a of the first embodiment.

[0105] <Effects of the cooling device 1b of the second embodiment> The cooling device 1b of the second embodiment described above provides the following effects. As shown in Figures 10 and 11, the cooling device 1b has a second air circulation path 9 that is rotatable in the width direction starting from the side of the second connection port 11, so the direction of the discharge port can be set toward a desired position or direction on the body 50. Since the second air circulation path 9 is rotatable about the rotation center C5, the direction of the second opening 12 can be easily changed and the direction of air discharge can be adjusted while the cooling device 1d is attached to the body 50.

[0106] <Configuration of the cooling device 1c of the third embodiment> Next, a configuration specific to the cooling device 1c of the third embodiment will be described. As shown in Figures 12 and 13, the second air circulation path 9 is bendable from the side of the second connection port 11 to the third end 91 and then to the fourth end 92, allowing the position or direction of the second opening 12 to be changed. In Figures 12 and 13, the bent second air circulation path 9 is shown by the dashed-dotted line. The other configurations are the same as those of the cooling device 1a of the first embodiment. Because the second air circulation path 9 has bending properties, it is formed by a flexible duct, for example. The flexible duct can be made of aluminum, iron, resin, etc. Note that the second air circulation path 9 is not limited to a flexible duct and may be formed from other materials that have bending properties.

[0107] In the example shown in Figure 12, the second air circulation path 9 is bendable in the width direction, which is the left-right direction shown in the figure, starting from the third end 91. The second opening 12 can be repositioned by being oriented diagonally relative to the longitudinal direction.

[0108] In the example shown in Figure 13, the second air circulation path 9 is bent at two points: the third end 91 and between the third end 91 and the fourth end 92. The second opening 12 can be repositioned to be tilted to the right with respect to the longitudinal direction as shown in the figure. In addition, the states in Figures 12 and 13 can be combined to tilt in both the width direction and the height direction.

[0109] <Effects of the cooling device 1c of the third embodiment> The cooling device 1c of the third embodiment described above provides the following effects. As shown in Figures 12 and 13, the cooling device 1c has a second air circulation path 9 that is bendable from the side of the second connection port 11 to the third end 91 and then to the fourth end 92. Since the position or direction of the second opening 12 of the cooling device 1c can be changed, the direction of the outlet can be set to face a desired position on the body 50.

[0110] In the example shown in Figure 12, the second opening 12 is bendable in the width direction starting from the third end 91, so that air can be discharged in a direction inclined with respect to the longitudinal direction. As will be described later with reference to Figure 30, when the cooling device 1c's second opening 12 is attached to the orthosis 31 so that it is on the head side and the device is worn on the body 50, air can be blown diagonally toward the neck 52 or head.

[0111] In the example shown in Figure 13, the second opening 12 can be attached to the body 50 while tilted toward the body. As will be described later with reference to Figure 28, the cooling device 1c can bend the second air circulation path 9 to blow air towards the neck, which is effective in lowering body temperature, through the second opening 12.

[0112] <Configuration of the cooling device 1d in the fourth embodiment> Next, with reference to Figure 14, the configuration specific to the cooling device 1d of the fourth embodiment will be described. The second air circulation path 9 of the cooling device 1d is expandable and contractible in the longitudinal direction, starting from the side of the second connection port 11. Figure 14(a) shows the second air circulation path 9 set to its standard length. Figure 14(b) shows the second air circulation path 9 shortened compared to Figure 14(a), and Figure 14(c) shows the second air circulation path 9 extended. The cooling device 1d allows adjustment of the longitudinal position of the second opening 12 by adjusting the longitudinal length of the second air circulation path 9. The second air circulation path 9 is, for example, a bellows duct.

[0113] <Effects of the cooling device 1d in the fourth embodiment> The cooling device 1d of the fourth embodiment described above provides the following effects. As shown in Figure 14, the cooling device 1d allows adjustment of the longitudinal position of the second opening 12 by adjusting the length of the second air circulation path 9 in the longitudinal direction. Therefore, the cooling device 1d can adjust the second opening 12 to a location that is effective in lowering body temperature, depending on the user's height or the position in which it is worn on the body 50.

[0114] Although the configuration and effects of the second air circulation path 9 in the cooling device 1b of the second embodiment to the cooling device 1d of the fourth embodiment have been described individually, it is also possible to combine all of these configurations.

[0115] <Contents of the cooling device 1e of the fifth embodiment> Next, the cooling device 1e of the fifth embodiment will be described with reference to Figures 15 to 21. The cooling device 1e is equipped with a second air circulation path 9 in the device body 2e. The second air circulation path 9 is formed, for example, by a first top surface portion 7a and a plurality of second rib portions 14 that protrude in a direction intersecting the first top surface portion 7a, and is formed in parallel with the first air circulation path 4 in the width direction. For example, there are two second rib portions 14. The first air circulation path 4 and the second air circulation path 9 will both be described as rectangular tubes extending in the longitudinal direction, but they may also be cylindrical.

[0116] As shown in Figure 16, the fan 3 is mounted on the first top surface 7a, similar to the cooling device 1a of the first embodiment, and protrudes outward in the height direction. The second air circulation path 9 has its third end 91 connected to the second connection port 11, extends inclined toward the body side shown in the figure with respect to the longitudinal direction, and is further bent to be formed parallel to the first air circulation path 4.

[0117] As shown in Figure 19, the second air circulation path 9 is positioned, for example, approximately in the center of the first air circulation path 4 in the width direction. The first air circulation path 4 is formed with approximately equal widths on either side of the second air circulation path 9.

[0118] As shown by the arrows in Figure 17, when the cooling device 1e is attached to the body 50 and the fan 3 is activated, air is drawn in from the first opening 5, passes through the first air circulation path 4, and reaches the first connection port 6. Furthermore, as shown in Figure 16, the air is discharged from the second connection port 11, which is connected to the exhaust port of the fan 3, through the second air circulation path 9, and out through the second opening 12.

[0119] Next, the first openings 5 ​​in the first air circulation path 4 will be described with reference to Figures 20 and 21. Near the first end 41, the first air circulation path 4 is formed in two rows in the width direction, flanking the second air circulation path 9. The first openings 5 ​​are formed in each of the first air circulation paths 4. The first opening 5 in the first example shown in Figure 20(a) opens towards the head side in the longitudinal direction at the first end 41, similar to Figure 18. The first opening 5 opens toward the head side while maintaining the width direction gap between the first rib portion 8 where the first air circulation path 4 is formed and the second rib portion 14 where the second air circulation path 9 is formed. The first openings 5 ​​in the second example shown in Figures 20(b) and 21(a) open toward both sides in the width direction on the leg side of the wall portion 41b formed at the first end 41 of the first air circulation path 4. In the third example shown in Figures 20(c) and 21(b), the first opening 5 has a first top surface 7a that opens on the leg side of the wall portion 41b formed at the first end 41 of the first air circulation path 4.

[0120] Next, the water supply channels 23 will be described. As shown in Figures 18 and 19, the first air circulation path 4 is formed in two rows in the width direction. The water supply channels 23 are formed in each of the first air circulation paths 4 and are formed in two rows as shown. As illustrated in Figure 4, and as shown in Figure 19, the water supply channels 23 are attached to the body side of the first top surface 7a.

[0121] Unlike the cooling device 1a of the first embodiment, as shown in Figure 18, the two rows of water supply channels 23 are connected directly from the pump 22 without passing through the outer circumference of the first rib section 8. Each water supply channel 23 is positioned, for example, approximately at the center of each first air circulation path 4 in the width direction.

[0122] As shown in Figures 18 and 19, a water supply channel 23 is attached to the second air circulation path 9 approximately at its center in the width direction. As shown in Figure 15, the water supply channel 23 is connected to the pump 22, positioned on the width direction side of the second rib section 14, passes through the second opening 12 to the second air circulation path 9, and extends to a position close to the second connection port 11.

[0123] As shown in Figure 19(a), the second air circulation path 9 of the cooling device 1e is formed by being surrounded by a first top surface 7a, two second rib sections 14, and a second bottom surface 16 facing the first top surface 7a. In this case, it is desirable that the first rib section 8 and the second bottom surface 16 lie on the same plane in the height direction. When the first rib section 8 and the second rib section 14, which are attached to the body 50 and form a longitudinal opening 10, come into contact with the body 50, the first air circulation path 4 becomes surrounded by the body 50. When the fan 3 operates in this state, negative pressure is generated in the first air circulation path 4 by the circulating air, and the first rib section 8, the second rib section 14, and the second bottom surface 16 are attracted to the body 50.

[0124] As another example, as shown in Figure 19(b), the second air circulation path 9 may be formed by the first top surface 7a and the two second rib portions 14. In this case, it is desirable that the first rib portion 8 and the second rib portions 14 lie on the same plane in the height direction. When the first rib portion 8 and the second rib portions 14, which are attached to the body 50 and form the longitudinal opening 10, come into contact with the body 50, the first air circulation path 4 becomes surrounded by the body 50. When the fan 3 operates in this state, negative pressure is generated in the first air circulation path 4 by the circulating air, and the first rib portion 8 and the second rib portions 14 are attracted to the body 50.

[0125] <Effects of the cooling device 1e of the fifth embodiment> The cooling device 1e described above provides the following effects. Since the second air circulation path 9 is formed in parallel with the first air circulation path 4 in the cooling device 1e, the second air circulation path 9 can be formed within the height range of the first air circulation path 4. Therefore, the cooling device 1e can have a lower height dimension compared to the cooling device 1a of the first embodiment.

[0126] Furthermore, as shown in Figures 16 and 19, the cooling device 1e suppresses interference between the airflow in the first airflow path 4 and the airflow in the second airflow path 9 when the second airflow path 9 is surrounded by the second bottom surface portion 16.

[0127] <Contents of the cooling device 1f of the sixth embodiment> Next, the cooling device 1f of the sixth embodiment will be described with reference to Figures 22 and 23. In the cooling device 1f, the device body 2f is equipped only with a first air circulation path 4, and does not have a second air circulation path 9 which is provided in the other embodiments. The first air circulation path 4 can be any of the forms described in the common section.

[0128] As shown by the arrows in Figure 23, the fan 3 of the cooling device 1f is capable of blowing air in both directions. When the cooling device 1f is attached to the body 50 and the fan 3 operates in one direction, air is drawn in from the first opening 5, goes to the first connection port 6, and is discharged from the fan 3. When the fan 3 operates in the other direction, air is drawn in from the fan 3, goes from the first connection port 6 to the first opening 5, and is discharged from the first opening 5. The configuration of the water supply channel 23 is the same as the water supply channel 23 in the first air circulation path 4 of the cooling device 1a.

[0129] <Effects of the cooling device 1f of the sixth embodiment> The cooling device 1f of the sixth embodiment described above provides the following effects. When the cooling device 1f is used with its longitudinal opening 10 facing the body 50, the air flowing through the first air circulation path 4 comes into direct contact with the body 50. Regardless of the direction of air flow through the first air circulation path 4, the air flowing through the longitudinal opening 10 comes into direct contact with the body 50. Therefore, it promotes the generation of heat of vaporization from sweat produced by the body 50, thereby having the effect of cooling the body 50.

[0130] As shown in Figures 22 and 23, the cooling device 1f has the same width dimensions as the cooling device 1a of the first embodiment, and its height can be made the lowest compared to the other embodiments. Furthermore, the cooling device 1f can be made lighter compared to the other embodiments. Therefore, the cooling device 1f has the effect of being less noticeable when attached to the body 50. Furthermore, the cooling device 1f has the effect of being easy to attach to a specific part of the body 50.

[0131] <<Description of Cooling Unit 30>> Next, with reference to Figures 25 to 32, a cooling device unit 30 and an orthosis 31 according to a second aspect of the present invention will be described. As shown in Figure 26, etc., the cooling device unit 30 comprises a cooling device 1 and an orthosis 31. As shown in Figure 27, etc., the cooling device 1 is attached to the orthosis 31 such that the fan 3 is positioned on the leg side of the body 50, and the first opening 5 is positioned on the neck 52 side of the body 50. As shown in Figures 27 and 28, the front-to-back direction is defined as the side of the user's face being the front and the side of their back being the rear. As shown in Figure 26, etc., the orthosis 31 of the cooling device unit 30 is fitted with a plurality of cooling devices 1.

[0132] Furthermore, as shown in Figures 29 and 30, the cooling unit 30 allows for changes in the mounting position and / or direction of the cooling device 1 relative to the appliance 31. Figure 29(a) shows the case where each cooling device 1a is mounted on the appliance 31 in a first state, and Figure 29(b) shows the case where each cooling device 1a is mounted on the appliance 31 in a second state. Figure 30(a) shows the case where each cooling device 1a is mounted on the appliance 31 in a third state, and (b) shows the case where cooling device 1a and cooling devices 1b through 1d are mounted on the appliance 31.

[0133] Furthermore, as shown in Figures 27, 28, and 32, the orthosis 31 of the cooling device unit 30 is equipped with a hanging portion 34. When worn on the body 50, one side is the head side and the other side is the leg side. The hanging portion 34 to which the cooling device 1 is attached is the starting point of the head side and the free end is the leg side.

[0134] Furthermore, as shown in Figure 26, the cooling device unit 30 is positioned such that the second opening 12 of the cooling device 1, which is attached to the orthosis 31, is adjacent to the neck 52 and / or the armpit 54 of the body 50.

[0135] Furthermore, as shown in Figure 26, the cooling device unit 30 is positioned such that the second opening 12 of the cooling device 1, which is attached to the orthosis 31, faces the neck 52 and / or armpit 54 of the body 50.

[0136] The configuration of the cooling device unit 30 described above will now be explained in more detail. As shown in Figure 32, the orthosis 31 comprises a shoulder portion 38 that the user places on their shoulder, hook-and-loop fasteners 33 for attaching the cooling device 1, and a pocket portion 36 for positioning the cooling device 1 adjacent to the user's armpit 54. The orthosis 31 has two rows of hook-and-loop fasteners 33 formed over a wide area along its longitudinal direction. Furthermore, a hanging portion 34 is formed in the central part in the width direction, and hook-and-loop fasteners 33 are formed on the head side and leg side of the hanging portion 34. The cooling device 1 can be attached to the area where the hook-and-loop fasteners 33 are formed.

[0137] As shown in Figure 2, the cooling device 1 is equipped with hook-and-loop fasteners 33 on the outer side in the height direction, on the side that is attached to the orthosis 31. The hook-and-loop fasteners 33 of the cooling device 1 are formed, for example, on the head side and the leg side in the longitudinal direction. The cooling device 1 can be attached to the orthosis 31 by bringing the hook-and-loop fasteners 33 formed on the outer side in the height direction into contact with the hook-and-loop fasteners 33 of the orthosis 31.

[0138] As shown in Figure 25, the orthosis 31 includes a buckle portion 37 for securing the cooling device unit 30 to the user's body 50. As shown in Figures 27(a), 28(a), and 32, the hanging portion 34 is formed with a constant width relative to the center of the orthosis 31 in the width direction. The hanging portion 34 is continuous with the base material 35 of the orthosis 31 and is formed to hang down from the head side to the leg side. As shown in Figures 27(a) and 28(a), the hanging portion 34 is formed to overlap with the base material 35 in the front-rear direction. The cooling device 1 attached to the hanging portion 34 is pivotable from the head side of the base material 35 and contacts the body 50 along the recess between the user's scapulae 51. Note that the hanging portion 34 is not limited to between the user's scapulae 51 and may be formed in other locations.

[0139] Figure 27 shows an example in which the cooling device 1a is attached to the cooling device unit 30. Figure 27(a) shows the cooling device 1a attached to the hanging portion 34 in contact with the recess between the user's shoulder blades 51. Air is discharged from the second opening 12 of the cooling device 1a along the longitudinal direction, which has the effect of cooling the back of the user's head. Figure 27(b) shows the cooling device 1a positioned further longitudinally toward the leg than in Figure 27(a), and in contact with the area around the user's shoulder blades 51. Air is discharged from the second opening 12 of the cooling device 1a along the longitudinal direction, which has the effect of cooling the user's back and shoulders.

[0140] Figure 28 shows an example in which the cooling device 1b is attached to the cooling device unit 30. Figure 28(a) shows the cooling device 1b attached to the hanging portion 34 in contact with the recess between the user's scapulae 51. Air is discharged diagonally from the second opening 12 of the cooling device 1b toward the user's neck 52, which has the effect of cooling the user's neck 52. Figure 28(b) shows the cooling device 1b positioned further toward the leg in the longitudinal direction than in Figure 28(a), and the cooling device 1b is in contact with the area around the user's scapulae 51. Air is discharged diagonally from the second opening 12 of the cooling device 1b toward the shoulder from the scapulae 51, which has the effect of cooling the user's back and shoulders.

[0141] Figure 29 shows the degree of freedom in the position where the cooling devices 1 can be attached to the orthosis 31 in the longitudinal direction. For example, the cooling devices 1 are attached in three rows along the longitudinal direction to the part that is on the user's back, and to the pocket parts 36 on both sides of the user's armpits 54. Figure 29(a) shows the three rows of cooling devices 1 positioned approximately in the center of the range in which they can be attached in the longitudinal direction. Figure 29(b) shows the state in which the three rows of cooling devices 1 have been moved and attached to the head side or the leg side, respectively, compared to Figure 29(a). In the example shown in Figure 29, the second opening 12 of each cooling device 1 is facing towards the head side along the longitudinal direction.

[0142] Figure 30 shows a case where the orientation of the second opening 12 in some of the cooling devices 1 is inclined with respect to the longitudinal direction. Figure 30(a) shows a case where some of the three rows of cooling devices 1 are mounted inclined with respect to the longitudinal direction. In this case, the second opening 12 in some of the cooling devices 1 is oriented in a direction inclined with respect to the longitudinal direction. For example, in the two rows on both sides of the three rows, the orientation of the cooling devices 1 may be inclined so that the second opening 12 faces the neck 52 or head. Figure 30(b) shows a case where some of the three rows of cooling devices 1 are cooling devices 1b or cooling devices 1c. In cooling devices 1b or cooling devices 1c, the second air circulation path 9 is inclined with respect to the longitudinal direction together with the second opening 12. For example, the second air circulation path 9 of cooling device 1b may be inclined so that the second opening 12 faces the neck 52 or head. Note that cooling device 1a shown in Figure 9 may be used instead of cooling devices 1b and cooling devices 1c.

[0143] The cooling devices 1 described with reference to Figures 1 to 30 each include a water storage tank 21, a pump 22, and a power supply unit 25. In contrast, as shown in Figure 31, when multiple cooling devices 1 are attached to the appliance 31, one set of water storage tanks 21, pumps 22, and power supply units 25 may supply power and water to the water supply channels 23 for each cooling device 1.

[0144] <Effects of the cooling device unit 30> The cooling unit 30 described above provides the following effects. As shown in Figure 26, the cooling unit 30 has the fan 3 of the cooling device 1 located on the leg side, so the noise from the fan 3 is less noticeable during use.

[0145] Furthermore, as shown in Figure 26 and other figures, the cooling device unit 30 has multiple cooling devices 1 attached to the orthotic device 31, so it can cool multiple parts of the body 50.

[0146] Furthermore, as shown in Figures 29 and 30, the appliance 31 of the cooling device unit 30 may allow for changes in the mounting position and / or mounting direction of the cooling device 1. In this case, the mounting position and / or mounting direction of the cooling device 1 can be changed to suit the user's body type or the area to be cooled.

[0147] Furthermore, as shown in Figures 27 and 28, the orthosis 31 of the cooling device unit 30 has a hanging portion 34 to which one of the cooling devices 1 is attached, with the head side as the starting point and the leg side as the free end. This allows the cooling device 1 to conform to the shape of the body 50 and make contact with recessed areas of the body 50, thereby enhancing the cooling effect.

[0148] Furthermore, as shown in Figures 26 to 28, the cooling unit 30 is positioned so that the second opening 12 is adjacent to the neck 52 and / or the armpit 54 of the body 50, allowing cooled air to be discharged at a position that is effective in lowering the user's body temperature.

[0149] Furthermore, as shown in Figures 26 to 28, the cooling device unit 30 is positioned so that the second opening 12 faces the neck 52 and / or armpit 54 of the body 50, allowing cooled air to be discharged in a direction that is effective in lowering the user's body temperature.
