Description

[Technical Field]

[0001] The present disclosure relates to electrically heated clothing. [Background technology]

[0002] Electrically heated clothing equipped with a heating element that is worn during cold seasons such as winter is known (see Patent Documents 1 and 2). Such electrically heated clothing increases the temperature inside the clothing by connecting a secondary battery to the heat generating section and causing the heat generating section to generate heat.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-100199 [Patent Document 2] Utility Model Registration No. 3229950 Summary of the Invention [Problem to be solved by the invention]

[0004] When the secondary battery runs out of power, the heat generating portion can no longer generate heat, so if the device 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 a hassle to carry around many secondary batteries, but a dead secondary battery must be recharged before it can be used again, so using many secondary batteries increases the hassle of charging them.

[0006] Furthermore, for example, when workers at a construction site or the like use electrically heated 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 the above circumstances, and one of its objects is to provide an electrically heated garment that can reduce the frequency of replacement of secondary batteries. [Means for solving the problem]

[0008] The electric heating clothing of the present disclosure includes: The clothes themselves, a heat generating portion provided inside the clothing body when worn; a power source that supplies power to the heat generating unit; and a sheet-shaped solar cell that supplies power to the power source. [Effects of the Invention]

[0009] According to the present disclosure, an electrically heated garment can be provided that can reduce the frequency of replacement of secondary batteries. [Brief explanation of the drawings]

[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, numbers or symbols may be omitted in some drawings.

[0013] <<First Embodiment>> An electrically heated garment 100 according to a first embodiment of the present disclosure will be described with reference to FIGS. 1 to 5. FIG.

[0014] FIG. 1 is a front view showing the front side of an electrically heated garment 100 according to a first embodiment of the present disclosure. FIG. 2 is a perspective view showing the back side of the electrically heated clothing 100 of the first embodiment according to the present disclosure. FIG. 3 is a front view showing the inside of the electrically heated clothing 100 of the first embodiment according to the present disclosure. FIG. 4 is a diagram showing the parts other than the clothing body 1 of the electrically heated clothing 100 of the first embodiment according to the present disclosure. FIG. 5 is a cross-sectional view taken along line AA in FIG.

[0015] In the first embodiment, the electrically heated clothing 100 is described as a vest, but the type of clothing that the electrically heated clothing 100 is made of is not particularly limited, and it may be a jacket, blouson, or the like.

[0016] As shown in Figures 1 to 3, the electrically heated clothing 100 comprises a clothing body 1, a heat generating section 2 (see Figure 3) provided inside the clothing body 1, a power source 3 (see Figure 3) that supplies power to the heat generating section 2, and a sheet-shaped solar cell 4 (see Figure 2) provided on the outer surface of the back side of the clothing body 1 that supplies power to the power source 3 (see Figure 3).

[0017] 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.

[0018] The electrically heated clothing 100 also includes a battery attachment mechanism 5 (see Figures 4 and 5) for detachably attaching the solar cell 4, and a heat generating unit attachment mechanism (not shown) for detachably attaching the heat generating unit 2.

[0019] [Clothes body 1] As shown in FIGS. 1 and 2, the clothing body 1 includes a torso portion 10 and a collar portion 11 provided at the center of the upper side of the torso portion 10. The clothing body 1 may have sleeves attached to the left and right sides of the upper side of the torso 10, like a jacket or blouson.

[0020] 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.

[0021] As shown in FIG. 1, the front body 10B and collar 11 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 electrically heated clothing 100.

[0022] 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 of the solar cell 4 (see Figures 3 and 4) will be located when the solar cell 4 is attached, as shown in Figure 2.

[0023] Therefore, the electrical wiring 4A for supplying the electricity generated by the solar cell 4, which will be located outside the torso 10 when the electrically heated clothing 100 is worn (for example, to the power source 3 in Figures 3 and 4), can be pulled inside the torso 10 when the electrically heated clothing 100 is worn, and can be connected to the power source 3 that is located inside the torso 10 when the electrically heated clothing 100 is worn.

[0024] In addition, as shown in FIG. 3, the torso 10 is provided with a power supply housing 10C located on the front body 10B side and on the inside of the electrically heated garment 100 when worn.

[0025] When the electrically heated clothing 100 is worn, the power source 3 (see FIG. 3) is housed in this power source housing section 10C.

[0026] [Heat generating part 2] The heat generating unit 2 includes a cover 20, a heater (not shown) housed within the cover 20, and a temperature adjusting unit (not shown) housed within the cover 20 that adjusts the temperature of the heater to a set temperature. For example, the temperature adjustment unit is a so-called thermostat, and power is supplied from the power source 3 to the heater via the temperature adjustment unit.

[0027] In addition, the heat generating unit 2 has a connection part 2B at its tip that can be detachably connected (electrically connected) to the power source 3, and a rear end that is connected (electrically connected) to the heat generating unit 2 (specifically, the temperature control unit) and is equipped with electrical wiring 2A for supplying power from the power source 3 to the heat generating unit 2.

[0028] In the first embodiment, an example is shown in which the electrically heated clothing 100 is provided with one heat generating section 2, but the number of heat generating sections 2 may be two or more.

[0029] In addition, in the first embodiment, the heat generating portion 2 is provided on the surface of the back body 10A, which is on the inside of the electric heating clothing 100 when worn, but the heat generating portion 2 may also be provided on the surface of the front body 10B, which is on the inside of the electric heating clothing 100 when worn.

[0030] Furthermore, the heat generating portion 2 does not necessarily have to be provided on the surface of the back body 10A that is on the inside of the electrically heated garment 100 when worn.

[0031] In this way, there may be multiple heat generating units 2, and they may be arranged anywhere on the surface that faces the inside of the electrically heated clothing 100 when worn.

[0032] [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.

[0033] 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).

[0034] 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.

[0035] The power supply 3 also includes a switch (not shown) for driving the heat generating unit 2. The switch (not shown) for driving the heat generating unit 2 may be connected to the power source 3 by a cord, and may be operable at a location different from the power source 3.

[0036] [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.

[0037] In Figure 5, 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; in reality, it is possible to make it thinner than the thickness of the back body 10A of the torso 10.

[0038] For example, if the solar cell 4 is a perovskite solar cell, the overall thickness can be set to, for example, about 1 mm.

[0039] 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.

[0040] 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.

[0041] As shown in Figure 5, the solar cell 4 includes a power generation section 41A (see also Figures 2 and 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 Figures 3 and 4), and an electrical wiring fixing section 43 (see Figure 3) to which the rear end of the electrical wiring 4A is connected (electrically connected).

[0042] The electrical wiring 4A has a connection portion 4B at its tip for connecting (electrically connecting) to a power source 3 or the like, and as described above, its rear end is fixed so as to be electrically connected to the electrical wiring fixing portion 43 described below.

[0043] (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.

[0044] In the following, an example in which one power generating section 41A is arranged in the photoelectric conversion region 41 will be described.

[0045] However, there is no limit to the number of power generating sections 41A arranged in the photoelectric conversion region 41, and the number of power generating sections 41A 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.

[0046] (Power Generation Section 41A) As shown in Figure 5, 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.

[0047] (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.

[0048] (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.

[0049] (3) Perovskite layer 41A3: The perovskite layer 41A3 is a layer that absorbs light and performs photoelectric conversion, and contains a perovskite compound.

[0050] (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.

[0051] (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) so that light from the light-receiving surface can pass through to the perovskite layer 41A3.

[0052] (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.

[0053] (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 5), 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 5), 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.

[0054] (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 rear 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 rear end portion of the electrical wiring 4A in a detachable manner, or conversely, it may be a fixing portion that fixes the rear end portion of the electrical wiring 4A in an unremovable manner.

[0055] [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 electrically heated clothing 100, which allows the solar cell 4 to be removed from the clothing body 1 before washing, etc.

[0056] As shown in Figure 5, the battery mounting mechanism 5 includes a first body side mounting portion 50 provided at a position on the clothing body 1 where the solar cell 4 is to be mounted, and a first battery side mounting portion 51 (see also Figure 4) provided on the back surface opposite the light receiving surface of the solar cell 4. Specifically, the first main body attachment portion 50 is provided on the outer surface of the back body portion 10A of the torso portion 10 when the electrically heated garment 100 is worn.

[0057] In the electrically heated clothing 100 of the first embodiment, a pair of battery attachment mechanisms 5 are provided on the left and right, that is, two battery attachment mechanisms 5 are provided, but this is not necessarily limited to this.

[0058] For example, the electrically heated clothing 100 may be provided with one battery attachment mechanism 5 that corresponds to the entire back surface opposite the light-receiving surface of the solar cell 4, excluding the electrical wiring fixing portion 43. Conversely, the electrically heated clothing 100 may be provided with three or more battery attachment mechanisms 5.

[0059] 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.

[0060] 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] The hook and loop fastener is also called Magic Tape (registered trademark) or Velcro (registered trademark).

[0065] 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.

[0066] 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.

[0067] [Heat generating unit mounting mechanism] The heat generating unit attachment mechanism (not shown) is a mechanism for removably attaching the heat generating unit 2 to the clothing body 1 of the electrically heated clothing 100, thereby allowing the heat generating unit 2 to be removed from the clothing body 1 and then washed, etc.

[0068] More specifically, the heat generating unit attachment mechanism (not shown) is a mechanism for detachably attaching the cover 20 of the heat generating unit 2 shown in FIG.

[0069] The heat generating unit attachment mechanism (not shown) includes a main body side second attachment portion (not shown) provided at a position where the heat generating unit 2 of the clothing main body 1 is attached, and a heat generating unit side second attachment portion (not shown) provided on the heat generating unit 2.

[0070] In the first embodiment, the heat generating unit attachment mechanism (not shown) includes a heat generating unit side second attachment portion (not shown) provided on the entire surface of the cover 20 facing the clothing body 1 when the heat generating unit 2 is attached to the clothing body 1, and a main body side second attachment portion (not shown) provided on the clothing body 1 corresponding to the heat generating unit side second attachment portion (not shown).

[0071] Therefore, in the first embodiment, the electrically heated clothing 100 is provided with one heat generating part attachment mechanism (not shown).

[0072] However, similarly to the battery attachment mechanism 5, the electrically heated clothing 100 may also be provided with two or more heat generating unit attachment mechanisms (not shown).

[0073] In the first embodiment, the heat generating unit mounting mechanism (not shown) is a hook-and-loop fastener having a pair of engaging surfaces, the main body side second mounting portion (not shown) is one of the pair of engaging surfaces, and the heat generating unit side second mounting portion (not shown) is the other of the pair of engaging surfaces.

[0074] Like the battery attachment mechanism 5, the heat generating unit attachment mechanism (not shown) does not have to be limited to a hook-and-loop fastener, and may be any other detachable fastening means.

[0075] In the electrically heated clothing 100 of the first embodiment described above, even if the heat generating section 2 consumes power from the power source 3, 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.

[0076] Furthermore, if the solar cell 4 is exposed to light while the heat generating unit 2 is not in operation, the power source 3 can be charged.

[0077] 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.

[0078] Furthermore, the power generation efficiency of solar cells 4 (for example, perovskite solar cells, etc.) has improved significantly, so in some cases it may even be possible to make the power source 3 never run out of battery.

[0079] <<Second embodiment>> Next, an electrically heated garment 100 according to a second embodiment of the present disclosure will be described with reference to FIG. FIG. 6 is a diagram for explaining the electrically heated clothing 100 of the second embodiment according to the present disclosure, and corresponds to FIG.

[0080] 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.

[0081] As shown in Figure 6, the second embodiment of the electrically heated clothing 100 has the same configuration as the first embodiment, but in addition, the electrically heated 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.

[0082] The charge controller 6 is equipped with a power receiving section (not shown) to which a connection section 4B provided at the tip of the electrical wiring 4A can be connected, and a power transmitting section (not shown) to which a 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.

[0083] 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.

[0084] 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.

[0085] In this way, when the electrically heated 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.

[0086] 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.

[0087] As explained above, 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 heated 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.

[0088] Similarly, even if the solar cell 4 is large enough to be attached to the heated 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.

[0089] 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).

[0090] 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.

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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 is provided with the power source housing 10C, which is provided on the front body 10B side and on the inside of the electrically heated clothing 100 when worn, as shown in FIG.

[0098] However, the electrically heated 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.

[0099] In this case, the electrical wiring 2A and the electrical wiring 4A may be routed to the power source 3 on the outside of the clothing body 1 when the electrically heated clothing 100 is worn.

[0100] The same applies to the charge controller 6 of the second embodiment, and the electrically heated clothing 100 may be provided with a charge controller housing section that can be attached to a belt or the like.

[0101] 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 clothing body 1 when the electrically heated clothing 100 is worn, but may be provided outside the clothing body 1 when the electrically heated clothing 100 is worn.

[0102] 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 electrically heated clothing 100 is worn.

[0103] 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 outer surface of the front side (front body 10B), which is located opposite the back side of the clothing body 1.

[0104] Furthermore, if the clothing body 1 has sleeves, the solar cells 4 may be provided in the sleeves.

[0105] In addition, some electrically heated clothing 100 are of an integrated type in which the heat generating section 2 cannot be removed from the clothing body 1, and in this way the heat generating section 2 may be integrated with the clothing body 1.

[0106] Furthermore, in the embodiment, the sheet-shaped solar cells 4 are provided on the clothing body 1 of the electrically heated 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]
