In the present embodiment, shirt-type clothes 101 are used, but the present invention is not limited thereto, and clothes 101 worn on the lower body such as pants may be used as shown in FIG. That is, one of the upper-body clothes 101 shown in FIG. 1 and the lower-body clothes 101 shown in FIG.

  FIG. 4 is a block diagram illustrating a configuration example of the power receiving apparatus 110. The power receiving device 110 is a power receiving device of a known wireless power feeding system using an electromagnetic induction phenomenon or an electromagnetic resonance phenomenon, specifically, a power receiving circuit 111 formed by an element such as a coil or a capacitor, and the power receiving circuit 111 receives power. The charging circuit 112 is configured to charge the secondary battery 120 with the generated power, and the control unit 113 is configured to control the entire power receiving apparatus. The circuit of the power receiving device 110 is preferably formed on a flexible substrate so as not to impair the flexibility of the garment 101.

  The position where the power receiving device 110 is attached is not particularly limited as long as it is on the clothing 101, such as the back side, the front side, the front side, and the back side. In the example illustrated in FIGS. 1 to 3, an example in which the power receiving device 110 is attached to the back side of the clothing 101 is illustrated. However, when the clothes 101 are hung on a charging hanger, which will be described later, the power receiving device 110 and the power supply unit of the charging hanger are easily positioned so that they are close to the portion of the clothes 101 that is hung on the charging hanger. It is desirable to provide the power receiving device 110.

  As the secondary battery 120, a known secondary battery using an aqueous electrolyte, a non-aqueous electrolyte, a polymer solid electrolyte, or the like can be used, but a polymer solid electrolyte is used so as not to impair the flexibility of the garment 101. In particular, a lithium secondary battery or a lithium ion secondary battery that is film-like and flexible can be used particularly suitably. In addition, the secondary battery 120 includes a protection circuit (not shown) that monitors the voltage and temperature of the battery and stops charging / discharging of the battery in the event of an abnormality in order to prevent problems such as heat generation due to overcharge / overdischarge. May be.

  As shown in FIG. 2, the power receiving device 110 and the secondary battery 120 are covered with a waterproof layer 130. As the waterproof layer 130, a resin material that is flexible and does not transmit moisture, such as a silicone rubber or a PET (polyethylene terephthalate) film, can be used.

  Here, when the waterproof layer 130 is attached to the side of the garment 101 that contacts the wearer's body 10 (upper side in FIG. 2), at least the wearer's body 10 contacts the waterproof layer 130 so as not to give the wearer a sense of incongruity.

  In the example of the present embodiment, since the portable electronic device 140 is also detachable from the garment 101, the portable electronic device 140 and the garment 101 are similar to the waterproof layer 130 and the fixing auxiliary cloth 170. Each fixing portion is provided with an engaging member such as a line fastener, a hook-and-loop fastener, a button, and a hook that are engaged with each other. In order to attach the portable electronic device 140 to the garment 101, the surface of the portable electronic device 140 on which the engagement member is disposed faces the surface of the garment 101 on which the engagement member is disposed, so that the portable electronic device 140 faces the surface. The engagement member 140 and the engagement member of the garment 101 may be engaged.

  In addition, in order to prevent moisture from entering the waterproof layer 130, an openable lid 180 is provided on the connector 150 to connect the portable electronic device 140 and the secondary battery 120 as shown in FIG. If not, the lid 180 may be closed as shown in FIG. Reference numeral 190 shown in FIG. 5A denotes a metal terminal of the connector 150 that is electrically connected to the secondary battery 120.

  In this embodiment, the secondary battery 120 and the portable electronic device 140 are connected via the connector 150 provided in the waterproof layer 130.

The detection result by the detection unit 220 is notified to a control unit described later of the power supply device 230.

  FIG. 8 is a block diagram illustrating a configuration example of the power supply device 230. The power supply device 230 includes a power supply circuit 231 for supplying power to the power supply unit 210 and charging the secondary battery 250, and a control unit 232 for controlling the entire power supply device.

As the secondary battery 250, a known secondary battery using an aqueous electrolyte, a non-aqueous electrolyte, a polymer solid electrolyte, or the like can be used without particular limitation.
As the marker 260, a design, a pattern, or a shape that becomes a mark for alignment when the clothes-type wearable device 100 is hung on the hanger 200 can be used without any particular limitation. In the present embodiment, the marker 260 is provided on the hanger 200 so as to correspond to the collar portion of the clothing 101. As shown in FIG. 9, when the clothes-type wearable device 100 is hung on the hanger 200 so that the collar portion of the clothes 101 matches the position of the marker 260, the power receiving device 110 of the clothes-type wearable device 100 and the power supply unit 210 of the hanger 200. The power transmission / reception efficiency between the two is maximized.

  However, the marker 260 is not limited to the examples shown in FIGS. Further, for example, a marker indicating the center position of the hanger 200 may be provided on the clothes-type wearable device 100, or a marker may be provided on the clothes-type wearable device 100 side, or a marker may be provided on both the clothes-type wearable device 100 and the hanger 200. It may be provided.

  Next, the power supply process of this embodiment will be described with reference to the flowchart of FIG. First, the control unit 232 of the power supply device 230 of the hanger 200 determines whether power is supplied from the power plug 240 (step 310 in FIG. 10).

  When power is supplied from power plug 240 (Yes in step 310), control unit 232 determines whether clothing type wearable device 100 is detected by detection unit 220 (step 320 in FIG. 10).

  When the detection unit 220 detects the presence of the clothes-type wearable device 100 (Yes in Step 320), the control unit 232 supplies power obtained from a commercial power supply or the like to the power supply unit 210 via the power plug 240. The power supply circuit 231 is controlled (step 330 in FIG. 10). At this time, the power supply circuit 231 appropriately converts the commercial power supply voltage and gives a voltage having a specification suitable for the power supply unit 210.

  By supplying power to the power feeding unit 210 in this way, power is transmitted from the power feeding unit 210 to the power receiving device 110 of the clothes-type wearable device 100 in a contactless manner, and the power received by the power receiving device 110 is used for the clothes-type wearable device 100. The secondary battery 120 is charged. At this time, the charging circuit 112 of the power receiving device 110 may appropriately convert the voltage obtained in the power receiving circuit 111 by power feeding from the power feeding unit 210 to give a voltage having a specification suitable for the secondary battery 120. .

  When the secondary battery 120 is fully charged, the control unit 113 of the power receiving apparatus 110 notifies the power supply device 230 of the hanger 200 that the secondary battery 120 is fully charged. For example, in the case of the electromagnetic resonance method, when the resonance Q value is changed on the power receiving device 110 side, the power transmission / reception efficiency between the power receiving device 110 and the power feeding unit 210 changes. The load impedance when the power feeding unit 210 is viewed from the side changes.

  Therefore, when the secondary battery 120 is fully charged, the control unit 113 of the power receiving device 110 changes the inductance of the coil or the capacitance of the capacitor of the power receiving circuit 111 (resonant circuit) of the power receiving device 110 to resonate. Is notified that the secondary battery 120 is fully charged. The control unit 232 of the power supply device 230 determines that the secondary battery 120 of the clothes-type wearable device 100 is fully charged when the load impedance when the power supply unit 210 is viewed from the power supply circuit 231 changes (FIG. 10). In step 380, Yes), the power supply circuit 231 is controlled to stop the power supply to the power feeding unit 210. When the secondary battery 120 is not fully charged, the process returns to step 310.

  On the other hand, when the presence of the clothes-type wearable device 100 is not detected by the detection unit 220 (No in step 320), the control unit 232 of the power supply device 230 uses the power obtained from the commercial power supply or the like via the power plug 240. The power supply circuit 231 is controlled to charge the secondary battery 250 (step 340 in FIG. 10). At this time, the power supply circuit 231 appropriately converts the voltage of the commercial power supply to give a voltage having a specification suitable for the secondary battery 250.

  Control unit 232 stops charging of secondary battery 250 when secondary battery 250 is fully charged (Yes in step 390 in FIG. 10). When the secondary battery 250 is not fully charged, the process returns to step 310.

  In addition, when power is not supplied from the power plug 240 (No in Step 310), the control unit 232 determines whether the clothes-type wearable device 100 is detected by the detection unit 220 (Step 350 in FIG. 10). In this case, since power is not supplied from the power plug 240, the power supply device 230 operates with the power stored in the secondary battery 250.

  When the detection unit 220 detects the presence of the clothes-type wearable device 100 (Yes in step 350), the control unit 232 stores enough power in the secondary battery 250 to supply power to the clothes-type wearable device 100. (Step 360 in FIG. 10). If the detection unit 220 does not detect the presence of the clothes-type wearable device 100, the process returns to step 310.

  Control unit 232 supplies power stored in secondary battery 250 to power supply unit 210 when power sufficient for power supply to clothes-type wearable device 100 is stored in secondary battery 250 (Yes in step 360).
