Description

[Technical Field]

[0001] The present disclosure relates to air-conditioned clothing. [Background technology]

[0002] BACKGROUND ART Air-conditioned clothing equipped with a blower is known to suppress a rise in the wearer's body temperature in a high-temperature environment (see Patent Document 1). In such an air-conditioned suit, a secondary battery is connected to a blower, and by driving the blower, outside air from outside the air-conditioned suit is supplied to the inside of the air-conditioned suit. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-33653 Summary of the Invention [Problem to be solved by the invention]

[0004] When the secondary battery runs out of power, the fan cannot be driven, so if the fan is to be used for a long period of time, it is necessary to carry many replacement secondary batteries.

[0005] However, not only is it troublesome to carry around many secondary batteries, but when a secondary battery runs out, it must be recharged before it can be used again.

[0006] For example, when workers at a construction site wear air-conditioned clothing, they have to stop work every time they need to replace a secondary battery, which reduces work efficiency.

[0007] The present disclosure has been made in consideration of these circumstances, and one of its objectives is to provide an air-conditioned suit that can reduce the frequency of secondary battery replacement. [Means for solving the problem]

[0008] The air-conditioned clothing of the present disclosure is The clothes themselves, a blower that supplies outside air to the inside of the clothing body when worn; a power source for supplying power to the blower; and a sheet-shaped solar cell that supplies power to the power source. [Effects of the Invention]

[0009] According to the present disclosure, an air-conditioned suit can be provided that can reduce the frequency of secondary battery replacement. [Brief explanation of the drawings]

[Figure 2] FIG. 1 is a perspective view showing the back side of an air-conditioned clothing according to a first embodiment of the present disclosure. [Figure 3] FIG. 2 is a diagram showing a portion of the air-conditioned clothing of the first embodiment according to the present disclosure other than the clothing body. [Figure 4] FIG. 3 is a cross-sectional view taken along line AA in FIG. 2. [Figure 5] FIG. 10 is a diagram illustrating an air-conditioned clothing according to a second embodiment of the present disclosure. DETAILED DESCRIPTION OF THE INVENTION

[0011] Hereinafter, modes for carrying out the invention (hereinafter referred to as "embodiments") will be described in detail with reference to the accompanying drawings. It should be noted that the same elements are denoted by the same numbers or symbols throughout the description of the embodiments.

[0012] However, not all numbers or symbols are assigned to all drawings, and in consideration of ease of viewing the drawings, some numbers or symbols may be omitted from some drawings.

[0013] <<First Embodiment>> An air-conditioned garment 100 according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 4. FIG.

[0014] FIG. 1 is a perspective view showing the front side of an air-conditioned clothing 100 according to a first embodiment of the present disclosure. FIG. 2 is a perspective view showing the back side of the air-conditioned clothing 100 of the first embodiment according to the present disclosure. FIG. 3 is a diagram showing the parts other than the clothing body 10 of the air-conditioned clothing 100 of the first embodiment according to the present disclosure. FIG. 4 is a cross-sectional view taken along line AA in FIG.

[0015] As shown in Figures 1 to 3, the air-conditioned clothing 100 comprises a clothing body 1, multiple (two in this example) fans 2 (see Figures 2 and 3) that supply outside air to the inside of the clothing body 1 (see Figures 1 and 2) when worn, a power source 3 (see Figure 3) that supplies power to the fans 2, and a sheet-like solar cell 4 (see Figures 2 and 3) that is provided on the outer surface of the back side of the clothing body 1 and supplies power to the power source 3 (see Figure 3).

[0016] The outer surface of the back of the clothing body 1 is considered to be a location that is likely to be exposed to sunlight when worn, and is therefore a suitable location for installing the sheet-shaped solar cells 4; however, the location for installing the sheet-shaped solar cells 4 does not have to be limited to the outer surface of the back of the clothing body 1.

[0017] The air-conditioned clothing 100 also includes a battery mounting mechanism 5 (see FIG. 4) for detachably mounting the solar cell 4, and a fan mounting mechanism (not shown) for detachably mounting the fan 2.

[0018] [Clothes body 1] As shown in Figures 1 and 2, the clothing body 1 comprises a torso 10, sleeves 11 attached to the left and right sides of the upper side of the torso 10, and a collar 12 provided in the center of the upper side of the torso 10.

[0019] As shown in FIG. 2, the torso portion 10 has a back body portion 10A that is the back side when worn, and a front body portion 10B that is the front side located opposite the back side when worn, as shown in FIG.

[0020] As shown in FIG. 1, the front body 10B and collar 12 are divided into left and right halves at the center when viewed from the front, and a zipper 10B1 is provided at the edge of the division to integrate the left and right halves. The zipper 10B1 is for the user to open and close when putting on or taking off the air-conditioned clothing 100.

[0021] In addition, the torso 10 has a pair of left and right air-blowing mechanism insertion openings (not shown) on the back body 10A side, near the waist and sleeves 11, into which the air-blowing mechanism accommodating section 21 (see Figure 3) described below can be inserted when the user wears the air-conditioned clothing 100.

[0022] The blower mechanism insertion opening (not shown) is large enough to insert the blower mechanism accommodating section 21 (see Figure 3), but is smaller than the outer edge 22 (see Figure 3) provided at the end of the blower mechanism accommodating section 21 described below.

[0023] Therefore, when the air-conditioning clothing 100 is worn and the air-blowing mechanism accommodating section 21 is inserted into the air-blowing mechanism insertion opening (not shown) from the outside to the inside of the torso 10, the air-blowing mechanism accommodating section 21 can only be inserted up to the point where the outer edge 22 provided at the end of the air-blowing mechanism accommodating section 21 abuts the outer surface of the torso 10.

[0024] Furthermore, the torso 10 is provided with an opening (not shown) for an electrical wiring fixing portion on the side of the back body 10A, which is provided at a position where the electrical wiring fixing portion 43 (see Figure 3) of the solar cell 4 will be located when the solar cell 4 is attached, as shown in Figure 2.

[0025] Therefore, the electrical wiring 4A for supplying (for example, supplying to the power source 3 in Figure 3) the electricity generated by the solar cell 4, which will be located outside the torso 10 when the air-conditioned suit 100 is worn, can be pulled inside the torso 10 when the air-conditioned suit 100 is worn, and can be connected to the power source 3 that is located inside the torso 10 when the air-conditioned suit 100 is worn.

[0026] In addition, as shown in FIG. 1, the torso 10 is provided with a power supply housing 10C located on the front body 10B side and on the inside of the air-conditioned clothing 100 when worn.

[0027] When the air-conditioned clothing 100 is worn, the power source 3 (see FIG. 3) is housed in this power source housing section 10C.

[0028] [Blower 2] The blower 2 includes a blowing mechanism (not shown), a casing 20 that houses the blowing mechanism, and electrical wiring 2A for supplying power from a power source 3 to the blower 2 (specifically, the blowing mechanism). The blower mechanism (not shown) and the casing 20 housing the blower mechanism, i.e., the blower 2 excluding the electrical wiring 2A, may be referred to as the blower 2 (fan).

[0029] In the first embodiment, the air-conditioned clothing 100 is provided with two blowers 2 (fans). However, the number of blowers 2 (fans) provided in the air-conditioned clothing 100 does not need to be limited to two.

[0030] For example, the air-conditioned clothing 100 may be provided with one air blower 2 (fan), or may be provided with three or more air blowers 2 (fans).

[0031] (Blower mechanism) The blower mechanism may be similar to that of a typical axial fan, and is equipped with a motor (not shown) and an impeller attached to the rotating shaft of the motor.The rotation of the motor causes the impeller to rotate, generating wind.

[0032] (Casing 20) The casing 20 is a part that houses the air blowing mechanism so as to allow the flow of air generated by the air blowing mechanism, and is provided with an air blowing mechanism housing section 21 and an outer edge section 22 provided at the end of the air blowing mechanism housing section 21 that is located outside the clothing body 1 when attached to the clothing body 1.

[0033] As explained above, the outer edge 22 is large enough to not pass through the air blowing mechanism insertion opening (not shown) provided on the back body 10A side of the torso 10, i.e., has an outer shape larger than the air blowing mechanism insertion opening (not shown).

[0034] On the other hand, as explained above, the air blowing mechanism accommodating section 21 has a size that allows it to pass through the air blowing mechanism insertion opening (not shown) provided on the rear body 10A side of the torso section 10, that is, an outer shape that is smaller than the air blowing mechanism insertion opening (not shown).

[0035] (Electrical wiring 2A) The electrical wiring 2A has a connection part 2B provided at the tip end that can be detachably connected (electrically connected) to a power source 3, and a connection part (not shown) provided at the base end, which is the end opposite the tip end, that can be detachably connected (electrically connected) to a blower mechanism (not shown).

[0036] In the first embodiment, the tip end of the electric wiring 2A is a single cable as an assembled cable, and the cable is separated midway to form two cables, forming a Y-shaped cable.

[0037] However, it is not necessary to be limited to this, and cables may be used for each of the air blowing mechanisms. That is, the number of electrical wirings 2A may be the same as the number of air blowers 2 (fans), and in the first embodiment, the number of electrical wirings 2A may be two (plural).

[0038] [Power 3] The power supply 3 is a so-called secondary battery that can be charged and discharged, and may be any type of battery, such as a lead acid battery, a nickel-metal hydride battery, a lithium ion battery, a NAS battery, a sodium ion battery, or an all-solid-state battery.

[0039] The power source 3 is equipped with a power transmission section (not shown) to which a connection section 2B (see Figure 3) provided at the tip of the electrical wiring 2A can be connected (electrically connected), and a power reception section (not shown) to which a connection section 4B (see Figure 3) provided at the tip of the electrical wiring 4A can be connected (electrically connected). The power supply 3 also includes a switch (not shown) for driving the fan 2.

[0040] The power sending unit (not shown) of the power source 3 is a power transmitting unit for sending out power from the power source 3, and the power receiving unit (not shown) of the power source 3 is a power receiving unit through which the power source 3 receives power.

[0041] [Solar cell 4] In the first embodiment, the solar cell 4 is a perovskite solar cell that can be formed into a thin, bendable sheet, and the following description will be given assuming that the solar cell 4 is a perovskite solar cell.

[0042] In Figure 4, the thickness of the solar cell 4 is drawn to be thicker than the thickness of the back body 10A of the torso 10, but this is to make the configuration of the solar cell 4 easier to see, and in reality it is possible to make it thinner than the thickness of the back body 10A of the torso 10.

[0043] For example, if the solar cell 4 is a perovskite solar cell, the overall thickness can be set to, for example, about 1 mm.

[0044] However, the solar cell 4 does not have to be limited to a perovskite solar cell, and may be any solar cell that can be formed into a thin, bendable sheet, similar to a perovskite solar cell.

[0045] For example, organic semiconductor solar cells using organic semiconductors are available in the form of thin, flexible sheets, so such organic semiconductor solar cells may be used as the solar cell 4.

[0046] As shown in Figure 3, the solar cell 4 includes a power generation section 41A (see Figure 4) provided in the photoelectric conversion region 41, a sealing section 42 that seals the power generation section 41A, electrical wiring 4A for supplying the generated electricity (for example, to the power source 3 in Figure 3), and an electrical wiring fixing section 43 (see Figure 3) to which the electrical wiring 4A is connected.

[0047] (Photoelectric conversion area 41) As will be described later, the photoelectric conversion region 41 is a region where a power generating section 41A having a perovskite layer 41A3 is disposed, thereby converting light into electricity.

[0048] In the following, an example in which one power generating section 41A is arranged in the photoelectric conversion region 41 will be described.

[0049] However, there is no limit to the number of power generating sections 41A to be arranged in the photoelectric conversion region 41, and the number of power generating sections 41A to be arranged in the photoelectric conversion region 41 may be determined according to the size of the photoelectric conversion region 41 required for the solar cell 4.

[0050] (Power Generation Section 41A) As shown in Figure 4, the power generation unit 41A includes a first electrode 41A1 (anode) provided on the back surface opposite the light-receiving surface, an electron transport layer 41A2 provided on the first electrode 41A1, a perovskite layer 41A3 serving as a photoelectric conversion layer provided on the electron transport layer 41A2, a hole transport layer 41A4 provided on the perovskite layer 41A3, a translucent second electrode 41A5 (cathode) provided on the hole transport layer 41A4, and a translucent base material 41A6 provided on the second electrode 41A5.

[0051] (1) First electrode 41A1: The first electrode 41A1 is an electrode for extracting electrons generated in the perovskite layer 41A3, and is connected to a wiring (not shown) for extracting a current. For example, the first electrode 41A1 can be made of an opaque metal material that functions as a general electrode, but a transparent electrode material may also be used.

[0052] (2) Electron transport layer 41A2: The electron transport layer 41A2 is a layer that allows electrons generated in the perovskite layer 41A3 to move to the first electrode 41A1, while preventing holes generated in the perovskite layer 41A3 from moving to the first electrode 41A1, and contains, for example, a halogen compound or a metal oxide.

[0053] (3) Perovskite layer 41A3: The perovskite layer 41A3 is a layer that absorbs light and performs photoelectric conversion, and contains a perovskite compound.

[0054] (4) Hole transport layer 41A4: The hole transport layer 41A4 is a layer that allows holes generated in the perovskite layer 41A3 to move to the second electrode 41A5, while preventing electrons generated in the perovskite layer 41A3 from moving to the second electrode 41A5, and can be made of, for example, a metal oxide.

[0055] (5) Second electrode 41A5: The second electrode 41A5 is an electrode that functions as a cathode, and is connected to a wiring (not shown). The second electrode 41A5 is made of a transparent electrode material such as indium tin oxide (ITO) or fluorine-doped tin oxide (FTO) in order to allow light from the light-receiving surface to pass through to the perovskite layer 11A3.

[0056] (6) Base material 41A6: The base material 41A6 is an insulating base material that serves as a starting material when forming the second electrode 41A5, the hole transport layer 41A4, the perovskite layer 41A3, the electron transport layer 41A2, and the first electrode 41A1, and is made of a translucent material to allow light from the light-receiving surface to pass through to the perovskite layer 41A3. For example, quartz glass, polyethylene terephthalate, etc. can be suitably used.

[0057] (Sealing portion 42) The sealing portion 42 comprises a first sheet 42A, which is a translucent barrier sheet, spaced apart from the substrate 41A6 on the light-receiving surface side (upper side in Figure 4), a second sheet 42B, which is a back sheet spaced apart from the first electrode 41A1 on the back surface side opposite the light-receiving surface (lower side in Figure 4), a translucent sealant 42C filled between the first sheet 42A and the second sheet 42B and the power generation portion 41A, and an outer edge portion 42D provided along the entire outer edge so as to seal the gap at the outer peripheral edges of the first sheet 42A and the second sheet 42B. The above-described configuration of the sealing section 42 is merely an example, and the configuration is not limited to this, and any configuration may be used as long as it can appropriately protect the power generation section 41A from moisture and the like.

[0058] (Electrical wiring 4A) The electrical wiring 4A is a cable for supplying the power generated by the solar cell 4 to, for example, the power source 3, and is provided with a connection part 4B at the tip end for connection (electrical connection) to the power source 3, etc. The electric wire 4A has a base end portion opposite to the tip end portion, which is fixed so as to be electrically connected to an electric wire fixing portion 43 described later.

[0059] (Electrical wiring fixing part 43) The electrical wiring fixing portion 43 is an outlet for sending out the electric power generated by the solar cell 4, and is the portion to which the base end of the electrical wiring 4A is electrically connected. In addition, the electrical wiring fixing portion 43 may be a fixing portion that fixes the base end of the electrical wiring 4A in a detachable manner, or conversely, it may be a fixing portion that fixes the base end of the electrical wiring 4A in an unremovable manner.

[0060] [Battery mounting mechanism 5] The battery attachment mechanism 5 is a mechanism for detachably attaching the solar cell 4 to the clothing body 1 of the air-conditioned clothing 100, which allows the solar cell 4 to be removed from the clothing body 1 and then washed, etc.

[0061] The battery mounting mechanism 5 includes a first body side mounting portion 50 provided at the position where the solar cell 4 is mounted on the clothing body 1, and a first battery side mounting portion 51 provided on the back surface opposite the light receiving surface of the solar cell 4. Specifically, the main body side first attachment portion 50 is provided on the outer surface of the back body portion 10A of the torso portion 10 when the air-conditioned clothing 100 is worn.

[0062] In the first embodiment, the battery mounting mechanism 5 is a hook-and-loop fastener having a pair of engaging surfaces, with the main body side first mounting portion 50 being one of the pair of engaging surfaces and the battery side first mounting portion 51 being the other of the pair of engaging surfaces.

[0063] For example, there are hook-and-loop fasteners of a normal type, a free type, and a snap-in type, and any type of hook-and-loop fastener may be used.

[0064] In addition, a normal type hook and loop fastener has a hook structure on one side and a loop structure on the other side, and when one side and the other side are brought together, the hook structure and the loop structure interlock and engage with each other.

[0065] In addition, a free-type hook-and-loop fastener has a loop structure and a hook structure on both one side and the other side, and when one side is brought together with the other side, the hook structure and the loop structure interlock and engage with each other.

[0066] Furthermore, a snap-in type hook-and-loop fastener has a protrusion structure with an enlarged tip on both one side and the other side, and when one side and the other side are brought together, the protrusions engage with each other.

[0067] The hook and loop fastener is also called Magic Tape (registered trademark) or Velcro (registered trademark).

[0068] Furthermore, in the above description, the battery attachment mechanism 5 is a hook-and-loop fastener, but it is not limited to a hook-and-loop fastener.

[0069] For example, the battery mounting mechanism 5 may be a snap button consisting of a pair of members having a recess and a protrusion, and detachably fastened by engaging the recess and the protrusion, or may be some other detachable fastening means.

[0070] [Blower mounting mechanism] The blower mounting mechanism (not shown) is a mechanism for removably mounting the blower 2 (fan) to the clothing body 1 of the air-conditioned clothing 100, thereby allowing the blower 2 (fan) to be removed from the clothing body 1 when washing, etc.

[0071] More specifically, the blower mounting mechanism (not shown) is a mechanism for detachably mounting a casing 20 that houses the blowing mechanism (not shown) of the blower 2 shown in Figure 3 to the clothing body 1 of the air-conditioned clothing 100.

[0072] The blower mounting mechanism (not shown) includes a main body side second mounting portion (not shown) provided at a position where the blower 2 (fan) is mounted on the clothing main body 1, and a blower side second mounting portion (not shown) provided on the blower 2 (fan).

[0073] Specifically, the second main body side mounting portion (not shown) is arranged along the pair of left and right air blower mechanism insertion openings (not shown) provided on the back body 10A side of the torso 10 described above, on the outer surface of the torso 10 when the air-conditioned clothing 100 is worn, so as to surround the air blower mechanism insertion openings (not shown).

[0074] In addition, the second blower side mounting portion (not shown) is provided on the surface of the outer edge portion 22 provided at the end of the blower mechanism accommodating portion 21 that faces the back body 10A of the torso 10 when the blower 2 (fan) is attached to the clothing body 1.

[0075] In the first embodiment, the blower mounting mechanism (not shown) is a hook-and-loop fastener having a pair of engagement surfaces, the main body side second mounting portion (not shown) is one of the pair of engagement surfaces, and the blower side second mounting portion (not shown) is the other of the pair of engagement surfaces.

[0076] It should be noted that the fan attachment mechanism (not shown), like the battery attachment mechanism 5, does not have to be limited to a hook-and-loop fastener, and may be any other detachable fastening means.

[0077] In the air-conditioned clothing 100 of the first embodiment as described above, even if the power of the power source 3 is consumed by the blower 2, the power generated by the solar cell 4 is supplied to the power source 3, and the power source 3 is charged in parallel, so the time until the power source 3 runs out of battery can be extended and the frequency of replacing the power source 3 (secondary battery) can be reduced.

[0078] Furthermore, if the solar cell 4 is exposed to light while the fan 2 is not in operation, the power source 3 can be charged.

[0079] In the first embodiment, the solar cell 4 is a perovskite solar cell, and therefore can generate electricity even under weak light such as that from indoor lighting, and the power source 3 can be charged even in such weak light.

[0080] Furthermore, while small fans and the like are becoming increasingly energy-efficient, the power generation efficiency of solar cells 4 (e.g., perovskite solar cells) has improved significantly, so in some cases it may even be possible to eliminate the need for a power source 3 that will run out of battery power.

[0081] <<Second embodiment>> Next, an air-conditioned garment 100 according to a second embodiment of the present disclosure will be described with reference to FIG. FIG. 5 is a diagram for explaining an air-conditioned clothing 100 according to a second embodiment of the present disclosure, and corresponds to FIG.

[0082] The basic configuration of the second embodiment is the same as that of the first embodiment, so the following mainly describes the differences from the first embodiment, and explanations of the similarities with the first embodiment may be omitted.

[0083] As shown in Figure 5, the air-conditioned clothing 100 of the second embodiment has the same configuration as the first embodiment, but in addition, the air-conditioned clothing 100 is equipped with a charge controller 6 interposed between the power source 3 and the solar cell 4, and electrical wiring 6A that electrically connects the charge controller 6 and the power source 3.

[0084] The charge controller 6 is equipped with a power receiving section (not shown) to which the connection section 4B provided at the tip of the electrical wiring 4A can be connected, and a power transmitting section (not shown) to which the connection section 6B provided at one end of the electrical wiring 6A can be connected. The electrical wiring 6A also has connection parts 6B provided at both ends thereof.

[0085] The power sending unit (not shown) of the charge controller 6 is a power transmitting unit for sending out power from the charge controller 6, and the power receiving unit (not shown) of the charge controller 6 is a power receiving unit through which the charge controller 6 receives power.

[0086] As explained above, one connection part 6B is connected to the power transmission part (not shown) of the charge controller 6, and the other connection part 6B is connected to the power receiving part (not shown) of the power source 3, and power is supplied from the charge controller 6 to the power source 3 via the electrical wiring 6A.

[0087] In this way, when the air-conditioned clothing 100 further includes a charge controller 6, the charge controller 6 may be accommodated together with the power source 3 in the power source accommodating section 10C that accommodates the power source 3 described above.

[0088] Further, the clothing body 1 may be provided with a charge controller housing section for housing a charge controller 6 separate from the power supply housing section 10C.

[0089] As explained earlier, the power generation efficiency of solar cells 4 (e.g., perovskite solar cells, etc.) has improved significantly, so even if the solar cells 4 are small enough to be attached to the air-conditioned clothing 100, there is a risk that the voltage of the solar cells 4 will become so high that it exceeds the upper limit of the voltage of the power source 3.

[0090] Similarly, even if the solar cell 4 is large enough to be attached to the air-conditioned clothing 100, there is a risk that the current of the solar cell 4 will become so large that it exceeds the upper limit of the current of the power source 3 in the future.

[0091] Furthermore, even if the solar cell 4 generates a high voltage and a large current that exceed the upper limit of the power supply 3 in the future, it is preferable to have a charge controller 6 between the solar cell 4 and the power supply 3, as the charge controller 6 will prevent overcharging (preventing power supply deterioration at high voltages) and overcurrent (preventing accidents at large currents).

[0092] On the other hand, even if there is no problem with the magnitude of the voltage and current as described above, if the solar cell 4 is directly connected to the power source 3, the following problem may occur.

[0093] When solar cell 4 is not generating electricity, the voltage of solar cell 4 becomes low and power supply 3 has a higher voltage, which results in current flowing from power supply 3 to solar cell 4 and the possibility of power supply 3 discharging.

[0094] When the solar cell 4 is generating power, the solar cell 4 has a higher voltage than the power supply 3, so that the current is prevented from flowing back to the solar cell 4 side.

[0095] To avoid such discharge, it is possible to disconnect the electrical wiring 4A of the solar cell 4 from the power source 3, or to provide a switch or the like that can cut off the flow of power between the solar cell 4 and the power source 3.

[0096] However, if one forgets to disconnect the electrical wiring 4A of the solar cell 4 from the power supply 3 or forgets to turn off the switch, the power supply 3 may discharge and run out of battery.

[0097] On the other hand, the charge controller 6 also has the function of preventing reverse current flow, so that when the solar cell 4 is not generating power, it can prevent current from flowing from the power source 3 to the solar cell 4, which would cause the power source 3 to discharge. For this reason, it is preferable to provide the charge controller 6.

[0098] However, this does not preclude an embodiment in which a switch for cutting off the flow of electricity between the solar cell 4 and the power source 3 is provided in place of the charge controller 6.

[0099] Although the present disclosure has been described above based on specific embodiments, it should be understood that the present disclosure is not limited to the above embodiments. For example, in the first embodiment, the torso 10 includes the power supply housing 10C provided on the front body 10B side and on the inside of the air-conditioned clothing 100 when worn, as shown in FIG.

[0100] However, the air-conditioned clothing 100 may be provided with a power supply housing that can be attached to a belt or the like, instead of the power supply housing 10C. In other words, the power supply storage section does not necessarily have to be provided in the clothing body 1.

[0101] In this case, the electrical wiring 2A and the electrical wiring 4A can be routed to the power source 3 on the outside of the clothing body 1 when the air-conditioned clothing 100 is worn.

[0102] The same applies to the charge controller 6 of the second embodiment, and the air-conditioned clothing 100 may be provided with a charge controller housing that can be attached to a belt or the like.

[0103] Furthermore, even when the power supply storage section 10C and the charge controller storage section are provided in the torso section 10, they do not need to be provided inside the main body 1 of the clothing when the air-conditioned clothing 100 is worn, but may be provided outside the main body 1 of the clothing when the air-conditioned clothing 100 is worn.

[0104] In such a case, the electrical wiring 2A and the electrical wiring 4A can be routed to the power source 3 on the outside of the clothing body 1 when the air-conditioned clothing 100 is worn.

[0105] In addition, the solar cells 4 do not need to be provided only on the outer surface of the back side of the clothing body 1, but may also be provided on the sleeves 11 and the like.

[0106] Furthermore, in the embodiment, the sheet-like solar cells 4 are provided on the clothing body 1 of the air-conditioned clothing 100, but the solar cells 4 themselves may be provided in a location other than the clothing body 1.

[0107] For example, solar cells 4 may be attached to items worn during work, such as a helmet, a waist bag, a safety belt, or a construction vest, and electrical wiring 4A may be connected to power source 3 to supply the electricity generated by solar cells 4 to power source 3.

[0108] Furthermore, the method of supplying the power generated by the solar cell 4 to the power source 3 does not have to be limited to connecting to the power source 3 via a wire using the electrical wiring 4A, and for example, the power generated by the solar cell 4 may be supplied to the power source 3 using wireless power supply technology.

[0109] For example, wireless power supply technologies include electromagnetic induction, electric field coupling, electromagnetic wave, and electromagnetic wave methods, and the method to be selected should be appropriate depending on the relationship between where the solar cell 4 is installed and where the power source 3 is installed.

[0110] Furthermore, when the charge controller 6 is provided, power may be supplied to the power source 3 via the charge controller 6 by using a wireless power supply technology so that power is transmitted from the solar cell 4 to the charge controller 6.

[0111] As such, the present disclosure also encompasses modifications and improvements to the embodiments within its technical scope, which will be apparent to those skilled in the art from the claims. [Explanation of symbols]
