DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, the battery cable, pump set, battery set, cooling set, and clothing of the embodiments will be described in detail with reference to the drawings. However, for the sake of convenience, the drawings referred to below show only the main components necessary for explaining each embodiment in a simplified form. Therefore, the battery cable etc. of the present disclosure may include any component not shown in the drawings referred to.

[0018] 1 to 3 are schematic diagrams showing an example of a cooling set 1. The cooling set 1 is used by, for example, a person 100 (in other words, a human body) and is capable of cooling the person 100. FIGS. 1 to 3 show an example of the cooling set 1 when being used by the person 100. It can also be said that FIGS. 1 to 3 show an example of the cooling set 1 after it has been assembled.

[0019] The cooling set 1 includes, for example, clothes 2 worn by the person 100, a cooling device 4 capable of cooling the person 100, at least one fan 6 for cooling the person 100, a battery 8, and a battery cable 9 connected to the battery 8. The battery 8 is capable of supplying power to the cooling device 4 and the fan 6 through the battery cable 9. The person 100 wearing the clothes 2 is cooled by the cooling device 4, and is also cooled by the rotation of the fan 6. The cooling set 1 that cools the person 100 can also be referred to as, for example, a cooling system.

[0020] Fig. 1 shows an example of a person 100 wearing clothing 2. Fig. 1 shows an example of the clothing 2 as viewed from the rear (in other words, from the back of the person 100). Fig. 2 shows an example of the clothing 2 as viewed from the front. Fig. 3 shows an example of the clothing 2 as viewed from the inside when spread out.

[0021] In this example, the clothing 2 is an upper garment. Specifically, the clothing 2 is a vest. However, the clothing 2 may be an upper garment other than a vest. For example, the clothing 2 may be a long-sleeved upper garment. Furthermore, the clothing 2 may be pants.

[0022] <About the fans> The fan 6 is attached to the garment 2. The fan 6 is, for example, detachable from the garment 2. The outer shape of the fan 6 is, for example, circular. The fan 6 may be attached to the back body part 21 of the garment 2 as in the example of Figs. 1 to 3, or may be attached to the front body part 20 of the garment 2. The fan 6 operates based on power supplied from a battery 8. A battery cable 9 that transmits power output by the battery 8 is connected to the fan 6. The fan 6 rotates based on the power transmitted by the battery cable 9.

[0023] FIG. 4 is a schematic diagram showing an example of a state in which the fan 6 is removed from the garment 2. As shown in FIG. 4, the rear body 21 of the garment 2 is provided with an attachment hole 29 to which the fan 6 is attached. The attachment hole 29 is, for example, circular in shape according to the outer shape of the fan 6. The fan 6 includes an intake section 60 (see FIG. 1) that takes in air into the fan 6, and an exhaust section 61 (see FIG. 3) that exhausts the air taken into the fan 6 to the outside of the fan 6. The fan 6 is attached to the attachment hole 29 so that the intake section 60 is located on the outside of the garment 2 and the exhaust section 61 is located on the inside of the garment 2. Specifically, the fan 6 is inserted into the attachment hole 29 so that the intake section 60 is located on the outside of the garment 2 and the exhaust section 61 is located on the inside of the garment 2, and then the peripheral portion of the fan 6 is fixed to the peripheral portion of the attachment hole 29 in the garment 2.

[0024] While rotating, the fan 6 draws in air from the outside to the inside of the garment 2 through the mounting hole 29. The air drawn into the inside of the garment 2 circulates within the garment 2 as the fan 6 rotates, and is exhausted to the outside of the garment 2 from the neckline or the like of the garment 2. This cools the body of the person 100 wearing the garment 2. The mounting hole 29 of the garment 2 serves as an intake port for the cooling air, and the neckline or the like of the garment 2 serves as an exhaust port for the cooling air.

[0025] Although one fan 6 is attached to the garment 2 in the example of FIGS. 1 to 3, a plurality of fans 6 may be attached to the garment 2.

[0026] <Example of cooling system configuration> Fig. 5 is a schematic diagram showing an example of the configuration of the cooling device 4. As shown in Fig. 5 and the above-mentioned Figs. 1, 3 and 4, the cooling device 5 includes, for example, a storage section 40, a cooling body 41, a circulation channel body 45 and a pump 47. The storage section 40 stores a cooling fluid 42. The cooling fluid 42 circulates in the circulation channel body 45. The pump 47 circulates the cooling fluid 42 in the circulation channel body 45. The cooling body 41 cools the cooling fluid 42 in the storage section 40. Hereinafter, the cooling fluid 42 may be simply referred to as the fluid 42.

[0027] The circulation flow path body 45 is, for example, a long and thin member and has a flow path (also called a circulation flow path) through which the fluid 42 flows. The circulation flow path body 45 may be, for example, a tube as shown in Figures 3 and 5, or may be a member of another shape. Both ends of the circulation flow path body 45 are connected to the storage section 40.

[0028] The circulation flow path body 45 is attached to the garment 2 as shown in Fig. 3. For example, the circulation flow path body 45 is attached to the inner surface of the garment 2 (in other words, the surface facing the person 100). The circulation flow path body 45 is attached in a serpentine manner, for example, to the inner surface of the back body 21 of the garment 2 and the inner surface of the front body 20 of the garment 2. The location where the circulation flow path body 45 is attached is not limited to the example of Fig. 3. Furthermore, the shape of the circulation flow path body 45 attached to the garment 2 is not limited to the example of Fig. 3.

[0029] The fluid 42 is, for example, a liquid. The liquid as the fluid 42 may be, for example, water or salt water.

[0030] Cooling body 41 is stored in storage section 40. Cooling body 41 is, for example, a hard-type, plate-shaped ice pack. Cooling body 41 is used after being cooled, for example, in a refrigerator or the like. Specific examples of cooling body 41 are not limited to the above. For example, cooling body 41 may be a rod-shaped hard-type ice pack, a soft-type flat ice pack, ice, or a frozen plastic bottle.

[0031] The storage unit 40 is, for example, in the shape of a flat bag, and contains the fluid 42 and the cooling body 41. The storage unit 40 can also be called, for example, a container. The storage unit 40 is divided into, for example, a cooling body accommodating space that accommodates the cooling body 41 and a fluid accommodating space that accommodates the fluid 42. The cooling body accommodating space and the fluid accommodating space are not connected to each other.

[0032] The storage section 40 has an inlet / outlet 400 for introducing and removing the cooling body 41 into and from the cooling body accommodating space. The inlet / outlet 400 can be, for example, an opening. The cooling body 41 is introduced into and accommodated in the cooling body accommodating space through the inlet / outlet 400. The cooling body 41 in the cooling body accommodating space cools the fluid 42 in the fluid accommodating space.

[0033] The storage unit 40 includes, for example, an opening / closing unit 401 that can open and close the entrance / exit 400. The opening / closing unit 401 is, for example, a strip fastener. The strip fastener as the opening / closing unit 401 may be, for example, a waterproof fastener. The opening / closing unit 401 may be something other than a strip fastener. For example, the opening / closing unit 401 may be a hook-and-loop fastener or a lid that opens and closes.

[0034] The storage unit 40 includes an inlet 402 through which the fluid 42 flows from the circulation channel body 45 into the fluid accommodation space, and an outlet 403 through which the fluid 42 flows out from the fluid accommodation space to the circulation channel body 45. The fluid 42 in the circulation channel body 45 flows into the fluid accommodation space through the inlet 402. The fluid 42 in the fluid accommodation space flows out to the circulation channel body 45 through the outlet 403. The circulation channel body 45 may be detachable from the storage unit 40.

[0035] The storage unit 40 is provided in, for example, the garment 2. As shown in Figs. 1 and 3, the garment 2 includes a storage unit housing 25 that houses the storage unit 40. The storage unit housing 25 is, for example, a pocket provided in the garment 2. The storage unit housing 25 is provided, for example, on the outer surface of the rear body 21 of the garment 2 (i.e., the back surface of the garment 2). The storage unit housing 25 includes an entrance 250 for inserting and removing the storage unit 40 into and from the storage unit housing 25. The entrance 250 is provided on the outer surface of the storage unit housing 25 (in other words, the back surface of the garment 2). The entrance 250 can also be said to be, for example, the mouth of a pocket provided on the back surface of the garment 2. The storage unit 40 that houses the fluid 42 and the cooling body 41 is inserted and housed in the storage unit housing 25 through the entrance 250.

[0036] The reservoir accommodation section 25 includes, for example, an opening / closing section 251 that can open and close the entrance / exit 250. The opening / closing section 251 is, for example, a strip fastener. The opening / closing section 251 may be something other than a strip fastener. For example, the opening / closing section 251 may be a hook-and-loop fastener or a lid that opens and closes.

[0037] 3, an insertion opening 252 is provided on the inner surface of storage unit accommodating section 25 (in other words, the surface facing person 100) through which circulation channel body 45 extending from storage unit 40 passes. Circulation channel body 45 connected to storage unit 40 is pulled out from insertion opening 252 to the outside of storage unit accommodating section 25 and attached to the inner surface of garment 2. Insertion opening 252 is sized so that storage unit 40 cannot pass therethrough.

[0038] The pump 47 can circulate the fluid 42 in the storage portion 40 and the circulation channel body 45. The pump 47 is located, for example, midway through the circulation channel body 45. The circulation channel body 45 is connected to the pump 47.

[0039] The pump 47 operates based on the power supplied from the battery 8. A battery cable 9 that transmits the power output by the battery 8 is connected to the pump 47. The pump 47 can circulate the fluid 42 in the storage portion 40 and the circulation flow path body 45 based on the power transmitted by the battery cable 9.

[0040] The pump 47 is provided in, for example, the garment 2. As shown in Figs. 1 and 3 etc., the garment 2 includes a pump housing 26 that houses the pump 47. The pump housing 26 is, for example, a pocket provided in the garment 2. The pump housing 26 is provided, for example, on the outer surface of the back body 21 of the garment 2 (i.e., the back surface of the garment 2). The pump housing 26 includes an opening 260 for inserting and removing the pump 47 into and from the pump housing 26. The opening 260 is provided on the outer surface of the pump housing 26 (i.e., the back surface of the garment 2). The opening 260 can also be said to be, for example, the mouth of a pocket provided on the back surface of the garment 2. The pump 47 is inserted into and housed in the pump housing 26 through the opening 260.

[0041] The pump housing 26 includes, for example, an opening / closing part 261 that can open and close the inlet / outlet 260. The opening / closing part 261 is, for example, a line fastener. The opening / closing part 261 may be something other than a line fastener. For example, the opening / closing part 261 may be a hook-and-loop fastener or a lid that opens and closes.

[0042] 3, an insertion opening 262 through which the circulation flow path body 45 connected to the pump 47 passes is provided on the inner surface of the pump housing section 26. The circulation flow path body 45 connected to the pump 47 is pulled out from the insertion opening 262 to the outside of the pump housing section 26 and attached to the inner surface of the garment 2. The insertion opening 262 is sized so that the pump 47 cannot pass through it.

[0043] In the cooling device 4 having the above configuration, the fluid 42 cooled by the cooling body 41 in the storage unit 40 flows out from the storage unit 40 to the circulation channel body 45 by the action of the pump 47. Then, the fluid 42 flows through the circulation channel body 45 attached to the garment 2 and returns to the storage unit 40 by the action of the pump 47. The body of the person 100 wearing the garment 2 is cooled by the cold fluid 7 flowing through the circulation channel body 45 attached to the garment 2. When the fluid 42 flows through the circulation channel body 45, the heat of the body of the person 100 is transferred to the fluid 42, and the temperature of the fluid 42 rises. The fluid 42 that returns from the circulation channel body 45 to the storage unit 40 is cooled again by the cooling body 41 in the storage unit 40, and the cooled fluid 42 flows out from the storage unit 40 to the circulation channel body 45, and then returns from the circulation channel body 45 to the storage unit 40 again. In this way, the fluid 42 circulates through the storage section 40, which contains the cooling body 41 that cools the fluid 42, and the circulation flow path body 45, so that the body of the person 100 is continuously cooled by the cooling device 4.

[0044] It is also possible that the internal space of reservoir 40 is not divided into a cooling body accommodating space and a fluid accommodating space, and cooling body 41 and fluid 42 are accommodated in the same space within reservoir 40.

[0045] In the above example, the cooling device 4 and the fan 6 are provided in the garment 2. Therefore, the cooling set 1 can be said to be, for example, a garment with a cooling function, a garment with a cooling device, or a garment equipped with a cooling system.

[0046] In this example, as shown in Figs. 1 and 4, the fan 6 and the mounting hole 29 are located, for example, around the storage section 40 and the storage section accommodating section 25. The fan 6 being located around the storage section 40 means, for example, that the shortest distance between the outer edge of the storage section 40 and the outer edge of the fan 6 is equal to or less than the diameter of the fan 6. The fan 6 being located around the storage section accommodating section 25 means, for example, that the shortest distance between the outer edge of the storage section accommodating section 25 and the outer edge of the fan 6 is equal to or less than the diameter of the fan 6. The mounting hole 29 being located around the storage section 40 means, for example, that the shortest distance between the outer edge of the storage section 40 and the outer edge of the mounting hole 29 is equal to or less than the diameter of the mounting hole 29. The mounting hole 29 being located around the storage section accommodating section 25 means, for example, that the shortest distance between the outer edge of the storage section accommodating section 25 and the outer edge of the mounting hole 29 is equal to or less than the diameter of the mounting hole 29.

[0047] In this way, when the fan 6 and the mounting hole 29 are located around the storage portion 40 and the storage portion housing portion 25, the temperature of the fluid 42 in the storage portion 40 is less likely to increase due to the cooling effect caused by the rotation of the fan 6. This improves the cooling effect of the cooling device 4.

[0048] In this example, the fan 6 and the mounting hole 29, the storage unit housing 25, and the storage unit 40 are located in the vertical direction. In other words, the fan 6 and the mounting hole 29, the storage unit housing 25, and the storage unit 40 are located along the length direction of the garment 2. The fan 6 and the mounting hole 29 are located, for example, below the storage unit housing 25 and the storage unit 40. The fan 6 and the mounting hole 29, the pump housing 26, and the pump 47 are located in the vertical direction. The fan 6 and the mounting hole 29 are located, for example, below the pump housing 26 and the pump 47.

[0049] Here, in many upper garments, the length in the vertical direction (in other words, the length direction) is greater than the length in the horizontal direction (in other words, the width direction). Therefore, when the fan 6 and the mounting hole 29, and the storage unit housing 25 and the storage unit 40 are located in the vertical direction, the storage unit housing 25 and the storage unit 40 can be made larger than when they are located in the horizontal direction. This allows the amount of fluid 42 that can be stored in the storage unit 40 to be increased. As a result, the cooling effect of the cooling device 4 on the person 100 can be improved.

[0050] Fan 6 and mounting hole 29 may be located above storage portion accommodating portion 25 and storage portion 40, or may be located below pump accommodating portion 26 and pump 47. Fan 6 and mounting hole 29 may be located in the left-right direction relative to storage portion accommodating portion 25 and storage portion 40. Fan 6 and mounting hole 29 may be located in the left-right direction relative to pump accommodating portion 26 and pump 47.

[0051] Also, the fan 6 and the mounting hole 29 may be located away from the reservoir housing 25 and the reservoir 40, rather than in the vicinity of the reservoir housing 25 and the reservoir 40. In this case, for example, in the examples of Figures 1 and 4, the positions of the fan 6 and the mounting hole 29 and the positions of the pump housing 26 and the pump 47 may be interchanged.

[0052] <Battery configuration example> The battery 8 is, for example, rechargeable. The battery 8 outputs, for example, a DC voltage Vb. The DC voltage Vb output by the battery 8 (also referred to as a battery output voltage Vb) is applied to the fan 6 through a battery cable 9 as, for example, a power supply voltage for the fan 6 (also referred to as a fan power supply voltage). The fan 6 operates based on the battery output voltage Vb.

[0053] Fig. 6 is a schematic diagram showing an example of the configuration of battery 8. As shown in Fig. 6, battery 8 includes, for example, a case 85 constituting the exterior of battery 8, a rechargeable battery pack 80, a power supply unit 81, an operation unit 82, a control unit 83, and a connector 84. The battery pack 80, the power supply unit 81, the operation unit 82, the control unit 83, and the connector 84 are housed in the case 85.

[0054] The battery pack 80 generates and outputs a DC voltage V1. The battery pack 80 is composed of, for example, a plurality of battery cells connected in series. Each battery cell is, for example, a rechargeable secondary battery cell. The DC voltage V1 is the total voltage of the plurality of battery cells connected in series. Hereinafter, the DC voltage V1 is also referred to as the battery pack voltage V1.

[0055] The power supply unit 81 is capable of converting the battery pack voltage V1 into a battery output voltage Vb and outputting the battery output voltage Vb. The battery output voltage Vb output from the power supply unit 81 is input to a connector 84. The power supply unit 81 may be referred to as, for example, a power supply circuit.

[0056] A battery cable 9 is connected to the connector 84. A battery output voltage Vb output by the power supply unit 81 is input to the battery cable 9 through the connector 84. A connector 900 of a battery side cable 90 (described later) provided on the battery cable 9 is connected to the connector 84. The connector 84 is detachable from the connector 900. A cable that transmits power for charging the battery pack 80 (also referred to as charging power) is also connected to the connector 84. The connector 84 outputs the input charging power to the power supply unit 81. The power supply unit 33 can charge each battery cell of the battery pack 80 based on the charging power supplied from the connector 84.

[0057] The battery output voltage Vb (in other words, the fan power supply voltage) is variable, for example. The power supply unit 81 can generate, for example, a plurality of types of voltages with different values ​​as the battery output voltage Vb. The power supply unit 81 can generate, for example, four types of voltages with different values. For example, the power supply unit 81 generates 6V as the smallest battery output voltage Vb, and generates 19V as the largest battery output voltage Vb. The battery output voltage Vb changes in four stages, for example, within a range of 6V to 19V.

[0058] The larger the value of the battery output voltage Vb, the larger the airflow of the fan 6. The battery 8 can set the airflow of the fan 6 in, for example, four stages. The power supply unit 81 sets the value of the battery output voltage Vb based on an instruction from the control unit 83, for example.

[0059] The assembled battery voltage V1 changes depending on the remaining charge of each battery cell of the assembled battery 80. When the set value of the battery output voltage Vb is greater than the assembled battery voltage V1, the power supply unit 81 steps down the assembled battery voltage V1 to generate the battery output voltage Vb. On the other hand, when the set value of the battery output voltage Vb is less than the assembled battery voltage V1, the power supply unit 81 steps up the assembled battery voltage V1 to generate the battery output voltage Vb.

[0060] The operation unit 82 is operated by a user. The operation unit 82 has, for example, an operation button. The operation button is, for example, a push button, and is also called an operation switch.

[0061] The control unit 83 controls the power supply unit 81 in response to a user operation on the operation unit 82. For example, the control unit 83 can instruct the power supply unit 81 to output the battery output voltage Vb or to stop outputting the battery output voltage Vb. The control unit 83 can also instruct the power supply unit 81 as to the set value of the battery output voltage Vb to be output.

[0062] All or some of the functions of the control unit 83 may be implemented by hardware circuitry that does not require software to implement the functions, and the control unit 83 may include at least one processor to provide control and processing power for performing various functions, as described in more detail below.

[0063] According to various embodiments, the at least one processor may be implemented as a single integrated circuit (IC) or as multiple communicatively connected integrated circuits (ICs) and / or discrete circuits. The at least one processor may be implemented according to various known techniques.

[0064] In one embodiment, a processor includes one or more circuits or units configured to perform one or more data computation procedures or processes, for example by executing instructions stored in associated memory. In other embodiments, a processor may be firmware (e.g., discrete logic components) configured to perform one or more data computation procedures or processes.

[0065] According to various embodiments, the processor may include one or more processors, controllers, microprocessors, microcontrollers, application specific integrated circuits (ASICs), digital signal processors, programmable logic devices, field programmable gate arrays, or any combination of these devices or configurations, or other known devices and configurations, to perform the functions described below.

[0066] In this example, the control unit 83 is configured with, for example, a microcomputer including a CPU (Central Processing Unit) and a memory, etc. The control unit 83 can also be said to be a control circuit. The control unit 83 can also be said to be a kind of computer.

[0067] The operation button of the operation unit 82 functions as, for example, a power button that controls the supply of power to the fan 6. When a predetermined operation is performed on the operation button while the power supply unit 81 is not outputting the battery output voltage Vb, the control unit 83 instructs the power supply unit 81 to output the battery output voltage Vb. The power supply unit 81 starts outputting the battery output voltage Vb in response to the instruction from the control unit 83. As a result, the battery output voltage Vb is supplied from the battery 8 to the fan 6 as a power source, and the fan 6 starts rotating. On the other hand, when a predetermined operation is performed on the operation button while the power supply unit 81 is outputting the battery output voltage Vb, the control unit 83 instructs the power supply unit 81 to stop outputting the battery output voltage Vb. The power supply unit 81 stops outputting the battery output voltage Vb in response to the instruction from the control unit 83. As a result, the supply of the battery output voltage Vb from the battery 8 to the fan 6 stops, and the rotation of the fan 6 stops.

[0068] As will be described later, the power supply voltage for the pump 47 is generated from the battery output voltage Vb. Therefore, when the power supply unit 81 starts outputting the battery output voltage Vb, not only the fan 6 but also the pump 47 starts operating. Also, when the power supply unit 81 stops outputting the battery output voltage Vb, not only the fan 6 but also the pump 47 stops operating. The operation button of the operation unit 82 can be said to function as a power button that controls the supply of power to the fan 6 and the pump 47.

[0069] The operation button of the operation unit 82 also functions as an adjustment button for adjusting the air volume of the fan 6. When a predetermined operation is performed on the operation button while the battery output voltage Vb is being supplied to the fan 6, the control unit 83 instructs the power supply unit 81 to change the set value of the battery output voltage Vb to be output. The power supply unit 81 changes the set value of the battery output voltage Vb to be output in response to the instruction from the control unit 83. This changes the value of the battery output voltage Vb supplied from the battery 8 to the fan 6, and changes the air volume of the fan 6. The value of the battery output voltage Vb supplied to the fan 6 changes cyclically between a plurality of set values, for example, every time a predetermined operation is performed on the operation button.

[0070] The battery 8 may include a display unit controlled by the control unit 83. The display unit may display, for example, the set value of the airflow rate of the fan 6, or may display the remaining charge of the battery pack 80. The remaining charge of the battery pack 80 may be obtained, for example, by the power supply unit 81 and notified to the control unit 83. The display unit may include a light-emitting unit such as an LED (Light Emitting Diode). The display unit may also include a liquid crystal display panel or an organic EL (Electroluminescence) panel.

[0071] <Example of battery cable configuration> Fig. 7 is a schematic diagram showing an example of the battery cable 9. As shown in Fig. 7 and the above-mentioned Fig. 3, the battery cable 9 includes, for example, a pump-side cable 91 connected to the pump 47 and a fan-side cable 95 connected to the fan 6. The pump-side cable 91 transmits power from the battery 8 to the pump 47. The fan-side cable 95 transmits power from the battery 8 to the fan 6. The battery cable 9 and the battery 8 may be collectively referred to as a battery set 50.

[0072] The battery cable 9 is branched, for example, at a branch point 99 midway through the cable 9 into a pump side cable 91 and a fan side cable 95. The pump side cable 91 extends from the branch point 99 to the pump 47, and the fan side cable 95 extends from the branch point 99 to the fan 6.

[0073] The battery cable 9 includes a battery side cable 90 extending from the battery 8 to a branch point 99. One end and the other end of the battery side cable 90 are connected to the battery 8 and the branch point 99, respectively. The pump side cable 91 extends from the other end of the battery side cable 90 to the pump 47, and the fan side cable 95 extends from the other end of the battery side cable 90 to the fan 6.

[0074] The battery side cable 90 is, for example, detachable from the battery 8. The battery side cable 90 has, at one end, a connector 900 which is detachable from the battery 8. The connector 900 is detachable from the connector 84 of the battery 8. For example, the connector 900 is a plug connector, and the connector 84 is a jack connector. Note that the connector 900 may be a jack connector, and the connector 84 may be a plug connector.

[0075] The fan-side cable 95 is, for example, detachable from the fan 6. The fan-side cable 95 has, at one end, a connector 950 which is detachable from the fan 6. The connector 950 is detachable from a connector included in the fan 6. For example, the connector 950 is a plug connector, and the connector included in the fan 6 is a jack connector. Note that the connector 950 may be a jack connector, and the connector included in the fan 6 may be a plug connector.

[0076] The pump-side cable 91 includes, for example, a first cable 911 connected to the pump 47 and a second cable 912 detachably connected to the first cable 911. One end and the other end of the first cable 911 are connected to the pump 47 and the second cable 912, respectively. One end of the first cable 911 is, for example, non-detachably connected to the pump 47. The other end of the first cable 911 is detachably connected to the second cable 912. The other end of the first cable 911 includes a connector 911a detachably connected to a connector 921a of the second cable 912. Note that one end of the first cable 911 may be detachably connected to the pump 47. The pump 47 and the first cable 911 connected thereto may be collectively referred to as a pump set 55.

[0077] One end and the other end of the second cable 912 are respectively connected to the branch point 99 and the first cable 911. The second cable 912 has, at the other end, a connector 912a that is detachable from the connector 911a that the first cable 911 has.

[0078] For example, the connector 912a is a plug connector and the connector 911a is a jack connector. Alternatively, the connector 912a may be a jack connector and the connector 911a may be a plug connector.

[0079] The battery cable 9 can be seen as being composed of a cable 980 consisting of a battery-side cable 90, a fan-side cable 95, and a second cable 912, and a first cable 911. The cable 980 is detachable from the battery 8, and is also detachable from the first cable 911. The cable 980 transmits power from the battery 8 to the fan 6, and also transmits power from the battery 8 to the first cable 911.

[0080] The battery 8 is provided in, for example, the clothing 2. As shown in Figs. 2 and 3 etc., the clothing 2 includes a battery storage section 27 that stores the battery 8. The battery storage section 27 is, for example, a pocket provided in the clothing 2. The battery storage section 27 is provided, for example, on the inner surface of the front body 20 of the clothing 2 (in other words, the surface facing the person 100). The battery storage section 27 includes, at its upper end, an entrance 270 for inserting and removing the battery 8 into and from the battery storage section 27. The entrance 270 can also be said to be, for example, the opening of a pocket provided on the inside of the clothing 2. The battery 8 is inserted into and stored in the battery storage section 27 through the entrance 270.

[0081] 3, an insertion opening 272 through which a battery side cable 90 connected to the battery 8 passes is provided on the inner surface of the battery housing section 27 (in other words, the surface facing the person 100). The battery side cable 90 is drawn out from the insertion opening 272 to the outside of the battery housing section 27. The insertion opening 272 is sized so that the battery 8 cannot pass through it.

[0082] The battery side cable 90 may be drawn out from the entrance 270 to the outside of the battery storage section 27. In this case, the battery storage section 27 does not need to have the insertion opening 272.

[0083] The fan 6 has a connector on the exhaust section 61 side. When the fan 6 is attached to the garment 2, the connector is located inside the garment 2. A fan-side cable 95 connected to a battery-side cable 90 pulled out from the battery housing section 27 extends along the inner surface of the garment 2 to the connector of the fan 6, and a connector 950 of the fan-side cable 95 is connected to the connector.

[0084] 3, an insertion opening 263 through which the pump side cable 91 is passed is provided on the inner surface of the pump housing section 26 of the garment 2 (in other words, the surface facing the person 100), as shown in FIG. 3. The pump side cable 91 connected to the pump 47 is pulled out from the insertion opening 263 to the outside of the pump housing section 26 and extends to the branch point 99.

[0085] 3, the battery housing section 27 does not include an opening / closing section capable of opening and closing the entrance 270, but may include such an opening / closing section. The opening / closing section may be a wire fastener, a hook-and-loop fastener, or a lid that opens and closes.

[0086] In the battery cable 9 having the above-mentioned configuration, the power output from the battery 8 is input to the pump 47 through the battery side cable 90, the branch point 99, the second cable 912 of the pump side cable 91, and the first cable 911 of the pump side cable 91 in this order. In addition, the power output from the battery 8 is input to the fan 6 through the battery side cable 90, the branch point 99, and the fan side cable 95 in this order.

[0087] A battery output voltage Vb outputted from the battery 8 is inputted as a fan power supply voltage to the fan 6 through a battery side cable 90 and a fan side cable 95. The fan 6 operates based on the battery output voltage Vb.

[0088] Furthermore, the battery output voltage Vb is input from the battery side cable 90 to the pump side cable 91. The pump side cable 91 has a voltage conversion circuit 10 that converts the battery output voltage Vb input to the pump side cable 91 into a power supply voltage Vp for the pump 47 (also referred to as a pump power supply voltage Vp), and transmits the power supply voltage Vp to the pump 47. The pump 47 has, for example, a DC motor. The pump 47 operates by driving the DC motor based on the pump power supply voltage Vp. The pump power supply voltage Vp is used as a power supply voltage for the DC motor.

[0089] The battery output voltage Vb (in other words, the fan power supply voltage) is set to be, for example, higher than the pump power supply voltage Vp. As described above, the battery output voltage Vb varies in a range of 6V to 19V depending on the set air volume of the fan 6. The pump power supply voltage Vp is, for example, 5V. The voltage conversion circuit 10 generates the pump power supply voltage Vp by, for example, stepping down the battery output voltage Vb. In this case, the voltage conversion circuit 10 can also be said to be a step-down circuit. The voltage conversion circuit 10 is provided, for example, in the middle of an electric wire 911b between the pump 47 and the connector 911a of the first cable 911 of the pump side cable 91. The electric wire 911b has a first electric wire 911ba that connects the voltage conversion circuit 10 and the connector 911a, and a second electric wire 911bb that connects the voltage conversion circuit 10 and the pump 47.

[0090] When the pump power supply voltage Vp is higher than the battery output voltage Vb, the voltage conversion circuit 10 boosts the battery output voltage Vb to generate the pump power supply voltage Vp. In this case, the voltage conversion circuit 10 can also be said to be a boost circuit.

[0091] When assembling the cooling set 1, the user may connect the first cable 911 and the second cable 912, for example, outside the pump housing 26. FIG. 8 is a schematic diagram showing one example of this state. FIG. 8 shows the pump housing 26 viewed from the inside of the garment 2. For convenience of illustration, the size of the pump 47 and the like is changed in FIG. 8 from FIGS. 1, 3, and 4. Also, in FIG. 8, the circulation flow path body 45 and the insertion port 262 of the pump housing 26 are omitted. The same applies to FIG. 9 described later.

[0092] For example, the user accommodates the pump set 55, i.e., the pump 47 and the first cable 911, in the pump accommodating section 26. Next, as shown in Fig. 8, the user takes out the connector 911a of the first cable 911 connected to the pump 47 from the insertion port 263 to the outside of the pump accommodating section 26. Then, the user connects the connector 911a taken out to the outside of the pump accommodating section 26 to the connector 912a of the second cable 912. This completes the connection between the first cable 911 and the second cable 912.

[0093] In this way, after the first cable 911 is partially removed from the insertion opening 263, the removed first cable 911 and the second cable 912 are connected, making it easier to connect the first cable 911 and the second cable 912.

[0094] After the connection between the first cable 911 and the second cable 912 is completed, the connection portion between the connector 911a and the connector 912a may remain located outside the pump accommodating portion 26. Alternatively, as shown in Fig. 9, the connection portion between the connector 911a and the connector 912a may be housed within the pump accommodating portion 26. In the example of Fig. 9, the connectors 911a and 912a are inserted into the pump accommodating portion 26 through the insertion port 263 after being connected to each other. As in the example of Fig. 9, by housing the connected connectors 911a and 912a within the pump accommodating portion 26, the connectors 911a and 912a are less likely to come off.

[0095] The user may connect the first cable 911 and the second cable 912 inside the pump accommodating section 26. For example, after accommodating the pump 47 and the first cable 911 in the pump accommodating section 26, the user may insert the connector 912a of the second cable 912 into the pump accommodating section 26 from the insertion opening 263. Thereafter, the user may insert his or her hand into the pump accommodating section 26 from the entrance / exit 260 of the pump accommodating section 26, and connect the connector 911a and the connector 912a inside the pump accommodating section 26.

[0096] In addition, the user may first insert the connector 912a of the second cable 912 into the pump accommodating section 26 through the insertion port 263, then remove the connector 912a to the outside of the pump accommodating section 26 through the entrance / exit 260, and connect the connector 912a to the connector 911a of the first cable 911 outside the pump accommodating section 26.

[0097] In the above example, the voltage conversion circuit 10 is provided midway through the electric wire 911b of the first cable 911, but as shown in Fig. 10, the voltage conversion circuit 10 may be provided in the connector 911a of the first cable 911. That is, the connector 911a may have the voltage conversion circuit 10. The voltage conversion circuit 10 is provided, for example, in a housing of the connector 911a.

[0098] As described above, in this example, the battery cable 9 has the pump side cable 91 connected to the pump 47 and the fan side cable 95 connected to the fan 6, so that it is possible to supply power to both the pump 47 and the fan 6 from one battery 8. This eliminates the need to prepare separate batteries 8 for the pump 47 and the fan 6, and allows the configuration of the cooling set 1 to be simplified.

[0099] In this embodiment, the voltage conversion circuit 10 converts the battery output voltage Vb into the pump power supply voltage Vp, so that it is possible to use a pump 47 having a power supply voltage different from the battery output voltage Vb. This improves the degree of freedom in selecting the pump 47 to be used. Even if the battery output voltage Vb is variable as in this embodiment, a constant power supply voltage can be supplied to the pump 47.

[0100] Of the battery cables 9, a cable 980 consisting of the battery side cable 90, the fan side cable 95, and the second cable 912 may be used as a battery cable in a cooling set that does not include a cooling device 4. For example, consider a second cooling set that includes a garment 2, two fans 6 attached thereto, a battery 8, and a second battery cable that transmits power from the battery 8 to the two fans 6. The second cooling set does not include a cooling device 4. The cable 980 of the battery cable 9 may be used as a second battery cable. In this case, the connector 950 of the fan side cable 95 is connected to the connector of one of the fans 6, and the connector 912a of the second cable 912 is connected to the connector of the other fan 6, so that power from the battery 8 can be transmitted to the two fans 6.

[0101] When the pump side cable 91 is divided into a first cable 911 and a second cable 912 as in this example, the cable 980 can be shared between the cooling set 1 including the cooling device 4 and the second cooling set not including the cooling device 4. Also, the battery set consisting of the cable 980 and the battery 8 can be shared between the cooling set 1 including the cooling device 4 and the second cooling set not including the cooling device 4.

[0102] As shown in FIG. 11, the pump side cable 91 does not have to be divided into the first cable 911 and the second cable 912.

[0103] Further, instead of providing the voltage conversion circuit 10 on the pump-side cable 91, a voltage conversion circuit 472 for converting the battery output voltage Vb into a power supply voltage for a motor included in the pump 47 may be provided on the pump 47. FIG 12 is a schematic diagram showing an example of the configuration of a pump 47 having a voltage conversion circuit 472.

[0104] 12, the pump 47 includes, for example, a motor 473, a voltage conversion circuit 472, a connector 471, and a case 470. The motor 473, the voltage conversion circuit 472, and the connector 471 are housed in the case 470.

[0105] Fig. 13 is a schematic diagram showing an example of a battery cable 9 connected to the pump 47 shown in Fig. 12. In the example of Fig. 13, a pump-side cable 91 is detachably attached to the pump 47. A connector 915 is provided at one end of the pump-side cable 91. The connector 915 is detachably attached to the connector 471 of the pump 47. The pump-side cable 91 transmits the battery output voltage Vb output by the battery 8 to the connector 471 of the pump 47.

[0106] The motor 473 is, for example, a DC motor. The voltage conversion circuit 472 converts the battery output voltage Vb input to the connector 471 into a power supply voltage Vm (also referred to as a motor power supply voltage Vm) for the motor 473. The motor power supply voltage Vm has the same value as the above-mentioned pump power supply voltage Vp, for example, 5 V. The voltage conversion circuit 472 generates the motor power supply voltage Vm, for example, by stepping down the battery output voltage Vb. Note that when the motor power supply voltage Vm is greater than the battery output voltage Vb, the voltage conversion circuit 472 steps up the battery output voltage Vb to generate the motor power supply voltage Vm.

[0107] 12 and 13 , when the pump-side cable 91 is detachably attached to the pump 47, for example, the connector 915 is inserted into the pump housing portion 26 through the insertion port 263. Then, the connector 915 is connected to the connector 471 of the pump 47 inside the pump housing portion 26.

[0108] Further, instead of providing the voltage conversion circuit 10 on the pump side cable 91, a voltage conversion circuit 86 for converting the battery output voltage Vb into the pump power supply voltage Vp may be provided on the battery 8. Fig. 14 is a schematic diagram showing an example of the configuration of the battery 8 having the voltage conversion circuit 86.

[0109] The battery 8 shown in FIG. 14 further includes a voltage conversion circuit 86 in addition to the battery 8 shown in FIG. 6 described above. The voltage conversion circuit 86 converts the battery output voltage Vb output by the power supply unit 81 into a pump power supply voltage Vp and outputs it to the connector 84, similar to the voltage conversion circuit 10. The battery output voltage Vb and the pump power supply voltage Vp are input to the connector 84. The battery output voltage Vb and the pump power supply voltage Vp output from the connector 84 are input to a battery side cable 90 of the battery cable 9. The battery side cable 90 transmits the battery output voltage Vb and the pump power supply voltage Vp to a branch point 99. A fan side cable 95 extending from the branch point 99 to the fan 6 transmits the battery output voltage Vb to the fan 6. A pump side cable 91 extending from the branch point 99 to the pump 47 transmits the pump power supply voltage Vp to the pump 47.

[0110] The voltage conversion circuit 86 may be provided in the power supply unit 81. In this case, the voltage conversion circuit 86 of the power supply unit 81 may convert the battery pack voltage V1 to a pump power supply voltage Vp and output the pump power supply voltage Vp to the connector 84.

[0111] When the cooling set 1 is used by a user (in other words, the person 100) (in other words, when the person 100 is wearing the cooling set 1), as shown in FIG. 3, the battery 8 may be located above the pump 47 (in other words, on the neckline side of the garment 2 or the head side of the person 100). That is, the entire battery 8 may be located above the entire pump 47. In this case, for example, even if the liquid fluid 42 leaks from the pump 47, the fluid 42 is unlikely to reach the battery 8 above the pump 47 through the battery cable 9. Therefore, the fluid 42 such as water is unlikely to get on the battery 8. As a result, for example, the battery 8 is unlikely to break down. Note that the positional relationship between the battery 8 and the pump 47 is not limited to this. For example, the battery 8 may be located below the pump 47 by providing the battery housing 27 below the pump housing 26 (in other words, on the hem side of the garment 2 or the feet side of the person 100).

[0112] Also, when the cooling set 1 is used, as shown in FIG. 3, the fan 6 may be located above the pump 47. That is, the entire fan 6 may be located above the entire pump 47. In this case, for example, even if the liquid fluid 42 leaks from the pump 47, the fluid 42 is unlikely to reach the fan 6 above the pump 47 through the battery cable 9. Therefore, the fluid 42 such as water is unlikely to get on the fan 6. As a result, for example, the fan 6 is unlikely to break down. Note that the positional relationship between the fan 6 and the pump 47 is not limited to this. For example, the fan 6 may be located below the pump 47 by swapping the positions of the fan 6 and the pump housing 26.

[0113] Also, when the cooling set 1 is used, as shown in FIG. 3, the lowest point 990 of the battery cable 9 may be located below the battery 8. That is, the lowest point 990 may be located below the entire battery 8. For example, when the fluid 42 is a liquid, the fluid 42 leaking from the pump 47 is likely to flow toward the lowest point 990, so that the fluid 42 is unlikely to reach the battery 8 above the lowest point 990 through the battery cable 9. Therefore, the fluid 42 such as water is unlikely to get on the battery 8. Note that the positional relationship between the battery 8 and the lowest point 990 is not limited to this. For example, the pump housing 26 may be provided on the side of the battery housing 27, so that the lowest point 990 may be located on the side of the battery 8.

[0114] Also, when the cooling set 1 is used, as shown in FIG. 3, the lowest point 990 of the battery cable 9 may be located below the fan 6. That is, the lowest point 990 may be located below the entire fan 6. For example, when the fluid 42 is a liquid, the fluid 42 leaking from the pump 47 is likely to flow toward the lowest point 990, so that the fluid 42 is unlikely to reach the fan 6 above the lowest point 990 along the battery cable 9. Therefore, the fluid 42 such as water is unlikely to splash on the fan 6. Note that the positional relationship between the fan 6 and the lowest point 990 is not limited to this. For example, the pump housing 26 may be provided above the fan 6 and the battery housing 27, and the fan 6 may be located on the side of the battery housing 27, so that the lowest point 990 may be located on the side of the fan 6.

[0115] 3, the lowest point 990 may be located on the pump side cable 91. In this case, even if the fluid 42 is, for example, a liquid, the fluid 42 leaking from the pump 47 is less likely to be transmitted to the fan side cable 95, and the fluid 42 is less likely to hit the fan 6. Note that the lowest point 990 may be located on the fan side cable 95 by, for example, positioning the fan 6 below the pump housing portion 26.

[0116] Furthermore, when the cooling set 1 is used, the battery 8 may be located above the branch point 99 of the battery cable 9 as shown in FIG. 3. That is, the entire battery 8 may be located above the branch point 99. In this case, even if the fluid 42 leaking from the pump 47 flows to the branch point 99, it is difficult for it to reach the battery 8 located above the branch point 99. Therefore, the fluid 42 is unlikely to get on the battery 8. Note that the positional relationship between the battery 8 and the branch point 99 is not limited to this. For example, the battery housing 27 may be provided below the pump housing 26, and the battery 8 may be located below the branch point 99.

[0117] Furthermore, when the cooling set 1 is used, as shown in FIG. 3, the fan 6 may be located above the branch point 99 of the battery cable 9. That is, the entire fan 6 may be located above the branch point 99. In this case, even if the liquid fluid 42 leaking from the pump 47 flows to the branch point 99, it is difficult for the liquid fluid 42 to reach the fan 6 above the branch point 99. Therefore, the fluid 42 is unlikely to hit the fan 6. Note that the positional relationship between the fan 6 and the branch point 99 is not limited to this. For example, the fan 6 may be provided below the pump accommodating section 26, and the fan 6 may be located below the branch point 99.

[0118] In the above example, the garment 2 is composed of one piece of clothing, but it may be composed of two pieces of clothing. Figures 15 and 16 are schematic diagrams showing an example of a cooling set 1 (also called cooling set 1A) including a garment 2 (also called garment 2A) composed of two pieces of clothing. Figure 15 corresponds to the above-mentioned Figure 3, and Figure 16 corresponds to the above-mentioned Figure 1.

[0119] 15 and 16, the garment 2A includes an inner garment 130 to which a circulation flow path body 45 is attached, and an outer garment 120 to which a fan 6 is attached, the outer garment 120 being located on the outside of the inner garment 130. For example, a person 100 puts on the inner garment 130, and then puts on the outer garment 120 on the outside of the inner garment 130. Each of the inner garment 130 and the outer garment 120 is, for example, a vest. Note that the inner garment 130 may be something other than a vest. Also, the outer garment 120 may be something other than a vest.

[0120] For example, two fans 6 are attached to the back of the outer garment 120. The battery cable 9 includes two fan side cables 95a and 95b connected to the two fans 6, respectively. The battery cable 9 branches into a fan side cable 95a, a fan side cable 95b, and a pump side cable 91 at a branch point 99. The number of fans 6 attached to the outer garment 120 may be one, or three or more. The battery cable 9 includes fan side cables in a number corresponding to the number of fans 6.

[0121] The outer garment 120 has a battery housing 125 similar to the above-mentioned battery housing 27. The battery housing 125 for housing the battery 8 is provided, for example, on the inner surface of the front body of the outer garment 120. The battery side cable 90 of the battery cable 9 is pulled out to the outside of the battery housing 125 from an insertion port 126 provided on the inner surface of the battery housing 125.

[0122] The cooling device 4 is provided, for example, in the inner garment 130. Figures 17 and 18 are schematic diagrams showing an example of the inner garment 130 provided with the cooling device 4. Figure 17 shows an example of the inner garment 130 as viewed from the back side. Figure 18 shows an example of the inner garment 130 as viewed from the front side.

[0123] The circulation flow path body 45 is attached, for example, to the inner surface of the inner garment 130. For example, the circulation flow path body 45 is attached to the inner surfaces of each of the rear body and the front body of the inner garment 130.

[0124] A reservoir housing portion 131 similar to the above-mentioned reservoir housing portion 25 is provided on the back surface of the inner garment 130. The circulation flow path body 45 is connected to the reservoir 40 within the reservoir housing portion 131.

[0125] A pump housing section 135 similar to the above-mentioned pump housing section 26 is provided on the back surface of the inner garment 130. The circulation channel body 45 is connected to a pump 47 in the pump housing section 135. A pump side cable 91 of the battery cable 9 is connected to the pump 47 in the pump housing section 135.

[0126] As described above, the garment 2A of the cooling set 1A includes the inner garment 130 to which the circulation flow path body 45 is attached, and the outer garment 120 to which the fan 6 is attached. This allows the cold air generated by the circulation of the cooling fluid 42 in the circulation flow path body 45 attached to the inner garment 130 to be trapped inside the outer garment 120. The cold air trapped inside the outer garment 120 can then be agitated by the rotation of the fan 6 attached to the outer garment 120.

[0127] Furthermore, when the outer garment 120 includes the battery storage section 125 as in this example, even if liquid fluid 42 leaks from the circulation flow path body 45 attached to the inner garment 130, the fluid 42 is less likely to come into contact with the battery 8.

[0128] The person 100 may wear only the inner garment 130 out of the outer garment 120 and the inner garment 130. In this case, the battery 8 may be housed in, for example, the pump housing 135. The battery cable 9 may be used as is, or a dedicated battery cable that connects the battery 8 and the pump 47, that is, a battery cable that does not include the fan-side cable 95, may be used instead of the battery cable 9.

[0129] Furthermore, the person 100 may wear only the outer garment 120 out of the outer garment 120 and the inner garment 130. In this case, a cable 980 consisting of the battery side cable 90, the fan side cable 95, and the second cable 912 may be used as a battery cable for transmitting power from the battery 8 to the two fans 6.

[0130] The outer garment 120 may include a reservoir housing that houses the reservoir 40 of the cooling device 4. The outer garment 120 may also include a pump housing that houses the pump 47 of the cooling device 4. The inner garment 130 may also include a battery housing that houses the battery 8.

[0131] In the above example, the battery cable 9 splits into a pump side cable 91 and a fan side cable 95 along the way, but as shown in FIG. 19, the pump side cable 91 and the fan side cable 95 may extend from the battery 8.

[0132] 19, the battery cable 9 does not branch midway, but includes two cables: a fan-side cable 95 that connects the battery 8 and the fan 6, and a pump-side cable 91 that connects the battery 8 and the pump 47. One end of the fan-side cable 95 on the battery 8 side is provided with a connector 951 that is connected to the battery 8. The connector 951 is detachable from the connector of the battery 8. The fan-side cable 95 transmits the battery output voltage Vb, which is input to the connector 951 from the battery 8, to the fan 6.

[0133] A connector 912b connected to the battery 8 is provided at one end of the pump-side cable 91 on the battery 8 side. The connector 912b is detachable from the connector of the battery 8. The pump-side cable 91 converts the battery output voltage Vb input from the battery 8 to the connector 912b into a pump power supply voltage Vp by the voltage conversion circuit 10 and transmits the pump power supply voltage Vp to the pump 47.

[0134] 14, when the battery 8 includes a voltage conversion circuit 86, the pump power supply voltage Vp output by the battery 8 is input to a pump-side cable 91 connected to the battery 8. The pump-side cable 91 does not include a voltage conversion circuit 10, and transmits the pump power supply voltage Vp output by the battery 8 to the pump 47.

[0135] In the above example, the battery 8, the storage unit 40, and the pump 47 are provided in the clothing 2, but at least one of the battery 8, the storage unit 40, and the pump 47 may be provided in a location other than the clothing 2. For example, at least one of the battery 8, the storage unit 40, and the pump 47 may be housed in a waist pouch or a backpack worn by the person 100.
