In this state, coils are respectively installed at predetermined positions in the power transmission unit 11 and the power reception unit 12 so that the power transmission efficiency when voltage is induced from the power transmission unit 11 to the power reception unit 12 is maximized. It may be a thing. By doing in this way, the state with high power transmission efficiency is maintained by the fitting part 13. Further, in the above description, the power receiving module 3 is described as being placed on the power transmitting module 2.

The power transmission unit 11 that is an internal circuit included in the power transmission module 2 and the power reception unit 12 that is an internal circuit included in the power reception module 3 are not exposed to the outside air, and the surfaces of both modules are waterproofed. Therefore, even if the power transmission module 2 and the power reception module 3 are installed in a place with a lot of moisture, there is no problem that a short circuit occurs.

  Hereinafter, a mechanism for supplying power from the power transmission module 2 to the power reception module 3 will be described with reference to the drawings.

  FIG. 3 is a block diagram illustrating an electrical configuration of the power transmission unit 11 included in the power transmission module 2 illustrated in FIG. 1 and the power reception unit 12 included in the power reception module 3. 3, the same parts as those in FIG. 1 are denoted by the same reference numerals, and detailed description thereof is omitted.

  The power transmission unit 11 includes a power primary coil 22 to which a commercial voltage is applied, a switching element 21 for switching whether or not to apply the commercial voltage to the power primary coil 22, and the switching element The switching control circuit 24 for controlling 21 is provided.

  Furthermore, the power transmission unit 11 includes a signal primary coil 29 for transmitting and receiving control signals to and from the power reception unit 12, and includes a power transmission control IC 23 that is controlled based on a control signal supplied from the power reception unit 12. In addition to the switching element 21 and the switching control circuit 24, the power transmission control IC 23 includes a carrier wave oscillation circuit 28, a demodulation circuit 30, a power transmission availability determination circuit 31, and an LED display circuit 32. The operation contents of these circuits will be described later.

  The operation content of the constituent elements included in the power transmission unit 11 will be described below.

  In the power transmission unit 11, the commercial voltage is applied from the distribution board 7 to the primary coil 22 for power constituting the transformer via the switching element 21. At this time, the switching element 21 may be configured by a transistor, or may be another switching element such as a MOSFET. For example, in the case of a transistor, a predetermined DC bias voltage (not shown) may be applied so that on / off control can be performed with respect to a commercial AC voltage. The switching element 21 is on / off controlled by a switching control circuit 24 as will be described later.

  The primary coil for power 22 constitutes a transformer together with the secondary coil for power 41 provided in the power receiving unit 12. When an AC voltage is applied to the primary coil for power 22, it is magnetically coupled. A voltage corresponding to the turns ratio of the power primary coil 22 and the power secondary coil 41 is induced at both ends of the power secondary coil 41. The turns ratio of the power primary coil 22 and the power secondary coil 41 is set to 1: 1, and the same voltage as the commercial voltage is generated at both ends of the power secondary coil 41. The voltage generated at both ends of the power secondary coil 41 included in the power receiving unit 12 is applied to the electronic device 5 through the cord 4, so that the electronic device 5 becomes available.

  The commercial voltage supplied from the distribution board 7 is applied to a primary side coil of a transformer 25 provided separately from the power primary side coil 22 and transformed to a predetermined voltage. At this time, the secondary side output voltage output to the secondary side coil of the transformer 25 is rectified by the rectifier circuit 26 and then smoothed by the smoothing circuit 27 including the capacitor C1 and the coil L1 to be the DC voltage Vcc. Is converted to This DC voltage Vcc is used as a control power source for a power transmission control IC 23 including a carrier wave oscillation circuit 28, a demodulation circuit 30, a power transmission availability determination circuit 31, and an LED display circuit 32, which will be described later, in addition to the switching control circuit 24 described above. . The power transmission control IC 23 is formed as an IC chip for the purpose of reducing the size and thickness of the power transmission unit 11.

  Further, the DC voltage Vcc is applied to the light emitting diode 34 through the switching element 33 and the overcurrent suppressing resistor R1. The switching element 33 is on / off controlled based on a signal from the LED display circuit 32, and the light emitting diode 34 emits light when the switching element 33 is in an on state. The light emitting diode 34 is controlled in light emission color by a lighting control circuit (not shown) based on a signal from the LED display circuit 32. Further, the switching element 33 may be configured by a transistor, or may be another switching element such as a MOSFET.

  The carrier wave oscillation circuit 28 is a circuit that outputs a predetermined carrier wave at regular intervals, and this output signal is given to the signal primary coil 29. The signal primary side coil 29 forms a transformer together with the signal secondary side coil 42 included in the power receiving unit 12. When an AC voltage is applied to the signal primary side coil 29, the signal primary side coil 29 is magnetically coupled. A voltage corresponding to the turn ratio of the primary side coil 29 and the signal secondary side coil 42 is induced at both ends of the signal secondary side coil 42.

  In addition to the power secondary coil 41 and the signal secondary coil 41, the power receiving unit 12 includes a smoothing capacitor C2, a rectifier circuit 43, a smoothing circuit 44 including a capacitor C3 and a coil L3. In addition, a power reception control IC 45 having a clock extraction circuit 46, a modulation circuit 47, a power-on reset circuit 48, and a voltage clamp circuit 49 to be described later is provided.

  As will be described later, the power-on reset circuit 48 detects a DC voltage converted from the carrier wave transmitted from the signal primary coil 29 and determines that there is a request for an information signal from the power transmission unit 11, thereby controlling power reception. This is a circuit for resetting the IC 45 and starting transmission of an information signal. The voltage clamp circuit 49 is a circuit for clamping the converted DC voltage to a predetermined voltage to prevent each circuit from being destroyed. The clock extraction circuit 46 and the modulation circuit 47 are connected to the signal secondary coil 42 and perform signal processing of signals transmitted via the signal primary coil 29 and the signal secondary coil 42. The power reception control IC 45 is formed as an IC chip in order to reduce the size and thickness of the power reception module 3.

  The voltage induced at both ends of the signal secondary coil 42 by the signal from the carrier wave oscillation circuit 28 is rectified and smoothed through the capacitor C2, the rectifier circuit 43, and the smoothing circuit 44 and converted into a DC voltage. When this DC voltage is applied to the power-on reset circuit 48, the power receiving unit 12 recognizes that the carrier wave is sent from the carrier wave oscillation circuit 28. Then, the clock extraction circuit 46 connected to the signal secondary coil 42 extracts a clock signal necessary for modulation from the carrier wave, and the modulation circuit 47 uses the clock signal supplied from the clock extraction circuit 46. Modulation is performed based on the “code indicating the information of the power reception unit 12”, and the modulated wave generated thereby is applied to the signal secondary coil 42. This “code indicating the information of the power receiving unit 12” indicates that the device provided with the power receiving unit 12 is mounted on the power transmitting unit 11 by the power transmission availability determination circuit 32 of the power transmitting unit 11 as described later. Used for judgment. As a modulation method at this time, a phase modulation method is used in which the carrier wave is intensity-modulated periodically and 0/1 information is expressed by the phase change information of the signal. As described above, since the clock signal necessary for modulation is extracted from the carrier wave transmitted from the power transmission unit 11, it is not necessary to have an oscillation circuit in the power reception unit 12, and for driving the clock extraction circuit 46 and the modulation circuit 47. Since a DC voltage generated from a carrier wave supplied from the carrier wave oscillation circuit 28 can be used as a power source, a driving power source is not required in the power receiving unit 12, and the circuit can be simplified.

  The modulated wave applied from the modulation circuit 47 to the signal secondary coil 42 is transmitted to the magnetically coupled signal primary coil 29. Then, the demodulation circuit 30 connected to the signal primary coil 29 receives and demodulates the transmitted modulated wave, and transmits the “code indicating the information of the power receiving unit 12” included in the demodulated information signal. The determination is given to the determination circuit 31. When the power transmission availability determination circuit 31 correctly receives this code, the power transmission availability determination circuit 31 determines that power transmission is possible, and gives a signal indicating an instruction command to enable power transmission to the switching control circuit 24. The switching control circuit 24 turns on the switching element 21. Power transmission begins. At this time, a signal indicating an LED display command is given from the power transmission availability determination circuit 31 to the LED display circuit 32, and the LED display circuit 32 turns on the switching element 33 so that the light emitting diode 34 emits light in a predetermined color. . As a result, it is possible to visually confirm that power transmission has started.

  Hereinafter, the flow of the power supply operation between the power transmission unit 11 and the power reception unit 12 will be described with reference to a flowchart. FIG. 4 is a flowchart illustrating the flow of the power supply operation performed between the power transmission unit 11 and the power reception unit 12.

  The power transmission unit 11 operates when a commercial voltage is supplied from the distribution board 7. At this time, the power transmission module 2 including the power transmission unit 11 is provided with an on / off control switch (not shown) that allows the user to operate the power transmission unit, and when the user turns on the power transmission unit on / off control switch, A configuration in which a commercial voltage is applied may be used. With this configuration, since the commercial voltage is not supplied to the power transmission unit 11 while the power transmission unit on / off control switch is in the off state, power is not consumed inside the power transmission unit 11 and power consumption is suppressed. Can do.

  When the commercial voltage is supplied to the power transmission unit 11, the control power supply Vcc of the power transmission control IC 23 is generated inside the power transmission unit 11 through the transformer 25, the rectifier circuit 26, and the smoothing circuit 27 as described above. Then, the control power supply Vcc is supplied to the LED display circuit 32, the LED display circuit 32 outputs a signal to the switching element 33, the switching element 33 is turned on, and the light emitting diode 34 emits red light (STEP 1). The light emission color of the light emitting diode 34 is determined based on a signal from a lighting control circuit (not shown) as described above, and the LED display circuit 32 gives a predetermined signal to the lighting control circuit. It is controlled by. Since the light emitting diode 34 emits red light, the user can visually confirm that the commercial voltage is supplied to the power transmission unit 11.

  When the control power source Vcc is supplied to the power transmission control IC 23, first, the carrier wave oscillation circuit 28 oscillates and outputs a predetermined carrier wave at regular intervals (STEP 2). This carrier wave is transmitted from the signal primary side coil 29 to the signal secondary side coil 42 as described above and applied to the power receiving unit 12. When the power-on reset circuit 48 detects the transmitted carrier wave, the power receiving unit 12 determines that an information signal is requested from the power transmitting unit 11. The carrier wave detected by the power-on reset circuit 48 is supplied to the modulation circuit 47, and the modulation circuit 47 modulates the carrier wave using the clock signal sent from the clock extraction circuit 46 as described above. A wave is generated and output to the signal secondary coil 42. The modulated wave transmitted to the signal secondary coil 42 is transmitted to the signal primary coil 29 and applied to the demodulation circuit 30 connected to the signal primary coil 29. The demodulating circuit 30 demodulates the given modulated wave, thereby extracting “a code indicating the information of the power receiving unit 12” included in the modulated wave, and sending the extracted information to the power transmission possibility determining circuit 31. Output.

  Then, when this “code indicating the information of the power receiving unit 12” is given to the power transmission availability determination circuit 31, it is recognized in the power transmission availability determination circuit 31 that the power reception unit 12 is placed on the power transmission unit 11 (STEP 3 Yes). At this time, the power transmission availability determination circuit 31 gives a predetermined signal to the LED display circuit 32 to light the light emitting diode 34 in green (STEP 4), and the switching control circuit 24 turns on the switching element 21. Give a control signal. Then, the switching control circuit 24 that has received this control signal turns on the switching element 21, whereby a commercial voltage is applied to the power primary coil 22 to start power transmission (STEP 5). Further, when the power receiving unit 12 is not placed, the power transmission availability determination circuit 31 cannot recognize the presence of the power receiving unit 12 (No in STEP 3), so the power receiving unit 12 is placed while the carrier wave is being output. Continue to check if it is. When the light emitting diode 34 emits green light, the user can visually confirm that power transmission to the power receiving unit 12 is started.

  Even after power transmission is started, the carrier wave continues to be output from the carrier wave oscillation circuit 28 at regular intervals (STEP 6), and it is continuously confirmed whether or not the power receiving unit 12 is placed on the power transmitting unit 11. If the power receiving unit 12 can still be recognized (YES in STEP 7), the power transmission is continued as it is and the carrier wave is continuously output at a constant interval (STEP 6). If the power receiving unit 12 cannot be recognized (No in STEP 7), it is determined that the power receiving unit 12 has been removed from the power transmission unit 11, and the power transmission availability determination circuit 31 turns the switching element 21 off with respect to the switching control circuit 24. A control signal to that effect is given. Then, the switching control circuit 24 that has received this control signal turns off the switching element 21, thereby cutting off the commercial voltage applied to the power primary coil 22 and stopping power transmission (STEP 8). Then, a predetermined signal is given to the LED display circuit 32 to light up the light emitting diode 34 again in red (STEP 1). Thereafter, while the commercial voltage is supplied to the power transmission unit 11, the power transmission unit 11 performs operation control to repeat the above steps STEP1 to STEP8. The light emitting diode 34 emits red light in STEP 1 and emits green light in STEP 4. However, the emission color is not limited to this.

  By configuring the power transmission module 2 and the power reception module 3 as described above, the power transmission unit 11 that is an internal circuit included in the power transmission module 2 and the power reception unit 12 that is an internal circuit included in the power reception module 3 are not exposed to the outside air. Since the waterproofing effect can be further enhanced by applying waterproof treatment to the surfaces of both modules, the power transmission module 2 and the power reception module 3 are installed in a place where there is much moisture. However, the problem of short circuit does not occur. That is, the power transmission module 2 can be installed in a place with a lot of moisture such as outdoors, a washroom, a bathroom, a kitchen, etc., and the power is supplied from the power reception module 3 placed on the power transmission module 2, thereby It is possible to use the electronic device 5 at the location.

  The operation of confirming the placement of the power receiving unit 12 performed in STEP 3 may stop supplying the commercial voltage to the power transmitting unit 11 when a time during which the presence of the power receiving unit 12 cannot be recognized continues for a predetermined time or longer. Absent. By doing in this way, consumption of standby power can be suppressed. At this time, since the control power supply Vcc of the power transmission control IC 23 is not generated, the light emitting diode 34 is turned off, and the user can visually recognize the state where the commercial voltage is not supplied to the power transmission unit 11.

  In FIG. 3, the power transmission unit 11 includes the power primary coil 22 and the signal primary coil 29. However, these coils may be realized by a single coil. Similarly, although the power receiving unit 12 includes the power secondary coil 41 and the signal secondary coil 42, these coils may be realized by a single coil.

  The power transmission module 2 and the power reception module 3 are not limited to the configuration shown in FIG. Other structural examples will be described below with reference to the drawings. In the following, the same parts as those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted.

  FIG. 5 is an enlarged schematic view of the state diagram (FIG. 1) in which the power receiving module 3 is mounted on the power transmitting module 2 attached to the wall surface, and is a configuration different from FIG. 2. In the configuration of FIG. 5, the power transmission module 2 includes a state holding magnet 51 instead of the fitting concave portion 14 and the power receiving module 3 is in the state instead of the fitting convex portion 15 in comparison with the configuration shown in FIG. A holding magnet 52 is provided. In addition, the polarity of the joint surface of the magnet 51 and the polarity of the joint surface of the magnet 52 are set to be opposite to each other. A pulling force is generated, and the mounted state is maintained.

  In addition, when comprised in this way, the magnet 51 and the magnet 52 do not affect the electric power supply to the power receiving part 11 by giving a magnetic field to the power transmission part 11 and the power receiving part 12. Both magnets may be covered with a material having a low magnetic permeability inside the module as long as 52 maintains the property of attracting stably. Further, either one of the magnet 51 and the magnet 52 may be replaced with a ferromagnetic material such as iron or nickel having a property of being attracted by the magnet.

  FIG. 6 is an enlarged schematic diagram of a state diagram (FIG. 1) in which the power receiving module 3 is mounted on the power transmitting module 2 attached to the wall surface, and is a configuration different from FIGS. 2 and 5. In the configuration of FIG. 6, the power receiving module 3 includes the suction cup 53 instead of the fitting convex portion 15, and the power transmission module 2 does not include the fitting concave portion 14 in comparison with the configuration illustrated in FIG. 2. The surface roughness of the surface facing the power receiving module 3 is reduced to such an extent that the suction cup is attached (surface 54). At this time, when the power reception module 3 is placed on the power transmission module 2, the suction cup 53 is stably adsorbed by the surface 54, and the placed state is maintained. The power receiving module 3 includes a suction cup. However, the power transmission module 2 includes a suction cup, and the surface of the power receiving module 3 is subjected to a process for reducing the surface roughness to the extent that the suction cup is attached. It doesn't matter.

  Further, as described above, in the present embodiment, the surface of the power transmission module 2 and the power reception module 3 is waterproofed. However, for example, when the room A is a room where water is prohibited. For example, when these modules are installed in a place where the possibility of moisture flowing into the inside is clearly low, the outer surface of these modules may not be waterproofed.

<Second Embodiment>
A second embodiment of the present invention will be described with reference to the drawings. FIG. 7 is a conceptual diagram of the power supply system in the present embodiment. The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

  The electric power supply system 1a shown in FIG. 7 is provided with a conventional electric power supply AC outlet 901 on the wall surface of the room A in advance as compared with the electric power supply system 1 shown in FIG. This AC outlet is wired in advance so that a commercial voltage is supplied. The power transmission module 2a has an AC outlet plug that can be inserted into an AC outlet outlet 902 (not shown in FIG. 7) provided in the conventional AC outlet 901 for power supply. When the AC outlet plug included in the power transmission module 2a is inserted into the power supply AC outlet 901, power is supplied from the power supply AC outlet 901 to the power transmission module 2a. When the power receiving module 3 is placed on the power transmission module 2 a in this state, power is supplied from the power transmission module 2 a to the power receiving module 3, and power is supplied from the power receiving module 3 to the electronic device 5 via the cord 4. Thus, the electronic device 5 becomes available. Note that the principle of supplying power from the power transmission module 2a to the power receiving module 3 is the same as the principle of supplying power from the power transmission module 2 to the power receiving module 3 in the first embodiment described above, and therefore the description thereof is omitted. To do. Further, as in the first embodiment, the power receiving module 3 may not be placed on the power transmission module 2a but may be brought close to a predetermined distance or less.

  FIG. 8 is an enlarged view of the power supply AC outlet 901, the power transmission module 2a, and the power reception module 3 in the power supply system 1a shown in FIG. FIG. 9 is a diagram illustrating a state in which the power receiving module 3 is placed on the power transmission module 2a in which the AC plug is inserted into the AC outlet insertion port 902 provided in the power supply AC outlet 901.

  The power transmission module 2a shown in FIG. 8 includes an AC outlet plug 61 in addition to the power transmission unit 11 and the magnet 51, and a commercial voltage is supplied to the power transmission unit 11 by inserting the plug 61 into the insertion port 902. The In the power transmission module 2a, the wall surface or the surface (surface 62) of the portion that comes into contact with the surface of the AC outlet 101 when the plug 61 is inserted into the insertion port 902 is formed of a sealing member such as rubber. By being configured in this manner, when the plug 61 is inserted into the insertion port 902, a gap is not formed between the plug 61 and the insertion port 902, and a short circuit occurs when water or the like enters the insertion port 902. Will not occur. Similarly to the first embodiment, the power reception module 3 includes a power reception unit 12, a magnet 52, and a cord 4, and the magnet 52 and the magnet 51 are set to have opposite polarities so as to attract each other. Furthermore, the magnet 51 and the magnet 52 have a property of attracting the magnet 51 and the magnet 52 stably so that the power supply to the power receiving unit 11 is not affected by applying a magnetic field to the power transmitting unit 11 and the power receiving unit 12. Both magnets may be covered with a low magnetic permeability material inside the module within the range to be maintained. Further, either one of the magnet 51 and the magnet 52 may be replaced with a ferromagnetic material such as iron or nickel having a property of being attracted by the magnet.

  At this time, as shown in FIG. 9, when the plug 61 is inserted into the insertion port 902 and the power receiving module 3 is placed on the power transmission module 2a, the commercial voltage supplied from the AC outlet 901 is given to the power transmission unit 11, Electric power is transmitted from the power transmission unit 11 to the power reception unit 12 by magnetic coupling. Then, power is sent from the power receiving unit 12 to the electronic device 5 via the cord 4, and the electronic device 5 becomes available.

  With this configuration, even when the conventional AC outlet 901 is already installed on a wall surface or the like, it can be used in the same manner as in the first embodiment by inserting the power transmission module 2a.

  In the above description, the power transmission module 2a includes the magnet 51, and the power reception module 3 includes the magnet 52. However, the present invention is not limited to this, and includes other state holding means described in the first embodiment. It does not matter. That is, the state of the power transmission module and the power reception module may be maintained by fitting the fitting convex part provided in one module and the fitting concave part provided in the other module, or the suction cup provided in one module May be held on the surface of the other module to maintain the state of the power transmission module and the power reception module. Since these state holding methods are the same as those described in the first embodiment, a detailed description thereof will be omitted.

  In the above description, the case where the conventional AC outlet 901 is installed on a wall surface or the like has been described. However, the installation location of the conventional AC outlet 901 is not limited to the wall surface or the like. For an extension cord or the like provided with an AC outlet insertion port, a plug of the power transmission module 2a may be inserted into the insertion port of the extension cord and the power reception module 3 may be placed on the power transmission module 2a. By using the extension cord in this way, the power supply system of this embodiment can be used even in a place where the conventional AC outlet 901 is not installed on the wall surface.

  Also in the present embodiment, as in the first embodiment, the power transmission module 2a and the power reception module 3 are included therein, for example, when the room A is a room where use of water is prohibited. In the case where the module is installed in a place where the possibility of inflow of water is clearly low, the outer surface of these modules may not be waterproofed.

<Third Embodiment>
A third embodiment of the present invention will be described with reference to the drawings. FIG. 10 is a conceptual diagram of the power supply system in the present embodiment. The same parts as those in the first and second embodiments are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the power supply system 1b shown in FIG. 10, the electronic device 5b includes a power reception module 3b inside, and commercial power is supplied to the electronic device 5b by placing the power transmission module 2b on the power reception module 3b. . The power transmission module 2 b includes a power transmission unit 11, a magnet 51, and a cord 64, and the cord 64 is provided with an AC outlet plug 65. The power receiving module 3b includes a power receiving unit 12 and a magnet 52. When the power transmitting module 2b is placed on the power receiving module 3b, both magnets generate a pulling force between the magnet 51 and the magnet 52. The polarity of the contact surface is set in reverse. The surface of the electronic device 5b is waterproofed so that moisture does not flow into the electronic device 5b.

  When the AC outlet plug 65 provided in the power transmission module 2b is inserted into the outlet outlet 902 of the conventional AC outlet 901, commercial power is supplied from the AC outlet 901 to the power transmission module 2b via the cord 64. In this state, when the power transmission module 2b is placed at a predetermined position on the electronic device 5b, magnetic coupling is established between the power transmission unit 11 included in the power transmission module 2b and the power reception unit 12 included in the power reception module 3b included in the electronic device 5b. As a result, electric power is supplied to the electronic device 5b (power receiving module 3b). Note that the principle of supplying power from the power transmission module 2b to the power reception module 3b is the same as the principle of supplying power from the power transmission module 2 to the power reception module 3 in the first embodiment described above, and therefore the description thereof is omitted. To do.

  When comprised in this way, since the electric power reception module 3b is provided in the inside of the electronic device 5b, the surface of the electronic device 5b can be made into a smooth structure. Conventional electronic devices need to be provided with an insertion port into which a plug is inserted in order to supply electric power. However, by configuring as in the present embodiment, it is not necessary to provide such an insertion port in the electronic device. Therefore, the problem that a short circuit occurs when power is supplied due to water entering the insertion port, which is included in conventional electronic devices, is avoided. Further, since the conventional electronic device is provided with the insertion port, for example, when the electronic device is transported, there is a problem that the hand touches the insertion port. Such a configuration eliminates the need for an insertion port and allows the external surface of the electronic device to be smoothly configured, so that such a problem does not occur. Furthermore, since an insertion port is not necessary, an electronic device that is preferable in terms of design can be provided.

  In the above description, the power transmission module 2b includes the magnet 51, and the power reception module 3b includes the magnet 52. However, the present invention is not limited thereto, and includes other state holding means described in the first embodiment. It doesn't matter. That is, the state of the power transmission module and the power reception module may be maintained by fitting the fitting convex part provided in one module and the fitting concave part provided in the other module, or the suction cup provided in one module May be held on the surface of the other module to maintain the state of the power transmission module and the power reception module. Since these state holding methods are the same as those described in the first embodiment, a detailed description thereof will be omitted.

  In addition, the surface of the electronic device 5b is waterproofed so that moisture does not flow into the electronic device 5b. Therefore, the power receiving module 3b included in the electronic device 5b is waterproof on the outer surface thereof. A configuration in which processing is not performed may be used. Further, when the electronic device 5b is an electronic device that is installed only in a place where use of water is prohibited, the electronic device 5b is installed in a place where the possibility of water flowing into the electronic device 5b and the power transmission module 2b is clearly low. In such a case, the outer surfaces of the power transmission module 2b and the electronic device 5b may not be waterproofed.

<Fourth Embodiment>
A fourth embodiment of the present invention will be described with reference to the drawings. FIG. 11 is a conceptual diagram of the power supply system in the present embodiment. In addition, the same code | symbol is attached | subjected about the part same as 1st, 2nd, and 3rd embodiment, and the detailed description is abbreviate | omitted.

  In the power supply system 1c shown in FIG. 11, the wall surface a1 of the room A is provided with a conventional power supply AC outlet 901. In addition, the other wall surface a <b> 2 of the room A is provided with a power transmission device 71 and is stably fixed by a stand 77. The power transmission device 71 includes a power transmission unit 11 and a cord 72, and an AC outlet plug 73 is provided at the tip of the cord 72.

  On the other hand, in the space C adjacent to the room A, the power receiving device 74 is provided on the wall surface c1 on the side in contact with the room A, and is stably fixed by the stand 78. The power receiving apparatus includes a power receiving unit 12 and a cord 75, and a power transmission pad 76 is provided at the tip of the cord 75. The power transmission pad 76 includes the power transmission unit 11 inside. Further, the electronic device 5 includes a cord 4, and a power receiving module 3 having a power receiving unit 12 is provided at the tip thereof. In addition, the power receiving module 3 is a structure which equips the inside with the power receiving part 12 similarly to each above-mentioned embodiment. FIG. 11 shows a state where the power receiving module 3 included in the electronic device 5 is placed on the power transmission pad 76. In addition, the outer surfaces of the power transmission device 71, the power reception device 74, and the power reception pad 76 are each waterproofed.

  When the AC outlet plug 73 is inserted into the insertion port 102 of the AC outlet 101, the commercial voltage is applied to the power transmission device 71 via the cord 72. Then, a magnetic coupling occurs between the power transmission unit 11 included in the power transmission device 71 and the power reception unit 12 included in the power reception device 74 via the wall ac surrounded by the wall surface a2 and the wall surface c1, and the power reception unit 12 is commercialized. Voltage is supplied. The commercial voltage supplied to the power receiving unit 12 is given to the power transmission pad 76 via the cord 75. At this time, when the power reception module 3 included in the electronic device 5 is placed on the power transmission pad 76, magnetic coupling occurs between the power transmission unit 11 included in the power transmission pad 76 and the power reception unit 12 included in the power reception module 3. A commercial voltage is supplied to the power receiving module 3, and the commercial voltage supplied to the power receiving module 3 is applied to the electronic device 5 via the cord 4, so that the electronic device 5 becomes available. Note that the principle of supplying power from the power transmitting device 71 to the power receiving device 72 and the principle of supplying power from the power transmitting pad 76 to the power receiving module 3 will be described below with respect to the power receiving module 3 from the power transmitting module 2 in the first embodiment. Since this is the same as the principle of supplying power to the device, its description is omitted. The wall ac is made of a material having a low magnetic permeability such as glass or nonmetal, and the width thereof is sufficiently thin. Therefore, the wall ac is between the power transmission unit 11 included in the power transmission device 71 and the power reception unit 12 included in the power reception device 74. Thus, it is possible to supply power by generating magnetic coupling.

  When configured in this way, for example, when the space C is an indoor room and there is no AC outlet to which a commercial voltage is supplied, the commercial voltage supplied from the adjacent room A can be used. Thus, the electronic device 5 can be used. At this time, since there is no need to provide an extension cord between the room A and the space C, it is possible to prevent a walking disorder caused by the extension cord crawling under the feet. Even when the extension cord does not reach the space C, the commercial voltage can be supplied to the space C according to the above configuration.

  Conventionally, in order to use an electronic device in a space where the extension cord cannot reach, a hole is made in the wall ac so that the extension cord reaches from the room A to the space C, and the electronic device is used in the space C. It was. For example, as shown in FIG. 12, in order to supply electric power to an electronic device 905 used in the space C from an AC outlet 901 provided on one wall surface in the room A, a work for providing a hole x in a part of the wall ac. Thus, the extension cord 912 can be passed from the room A to the space C. At this time, the AC outlet plug 911 provided in one of the extension cords 912 is inserted into the insertion port 902 of the AC outlet 901, and the cord 904 attached to the electronic device 905 is inserted into the insertion port 913 provided in the other end of the extension cord 912. By inserting the AC plug 903 at the tip, commercial voltage is supplied from the AC outlet 901 to the electronic device 905 via the extension cord 912 and the cord 904, and the electronic device 905 becomes usable.

  However, according to the configuration of the present embodiment, a commercial voltage can be supplied to the power receiving device 74 installed in the space C by causing the power transmitting device 71 and the power receiving device 74 to face each other across the wall ac. Therefore, it is not necessary to make a hole in a part of the wall ac, and external damage to the wall can be avoided. In addition, since both the power receiving device 74 and the power transmission pad 76 have a flat surface and are not provided with an insertion port provided in a conventional AC outlet, for example, even when the space C is outdoors, water is received by the power receiving device 74 or power transmission. There is no problem of entering into the pad 76 and causing a short circuit.

  FIG. 13 is a diagram illustrating the appearance of the power transmission device 71 and the power reception device 74 according to the present embodiment. FIG. 13A illustrates the power transmission device 71, and FIG. 13B illustrates the power reception device 74. As described above, the power transmission device 71 is stably installed by the stand 77, and the power receiving device 74 is stably installed by the stand 78.

  Fig.13 (a) is an external view when the power transmission apparatus 71 is seen from the wall surface a2 to the wall surface a1 in FIG. The power transmission device 71 includes a stand 77 and a stand base 79 attached thereto, and the power transmission device 71 is stably fixed by placing the stand base 79 on the floor surface of the room A. Similarly, FIG.13 (b) is an external view when the power receiving apparatus 74 is seen from the wall surface c1 in FIG. 11 in the direction opposite to the wall surface a1. The power receiving device 74 includes a stand 79 and a stand base 80 attached thereto, and the stand base 80 is placed on the floor surface of the space C (on the ground in the case of the outdoors), whereby the power receiving device 74 is It is fixed stably. With this configuration, both the power transmission device 71 and the power reception device 74 can be stably installed at predetermined locations. At this time, by configuring the stand 77 and the stand 79 with a stand whose height can be adjusted, the installation height of the power transmitting device 71 and the power receiving device 74 can be adjusted.

  Furthermore, when the wall ac ′ that partitions the room A and the space C is made of, for example, glass and the like and the surface roughness is reduced to such an extent that the suction cups can be attached, as shown in FIG. With the configuration, there is no need to provide a stand and a stand. FIG. 14 is another configuration example of the power transmission device and the power reception device in the present embodiment.

  Compared with the power transmission device 71 shown in FIGS. 11 and 13, the power transmission device 71 a shown in FIG. 14 includes a suction cup 81 instead of the stand 77 and the stand base 79. 14 includes a suction cup 82 instead of the stand 78 and the stand base 80, as compared with the power receiving device 74 shown in FIGS. Further, the wall surface of the wall ac 'is subjected to a process for reducing the surface roughness to such an extent that the suction cups are adsorbed on both the wall surface a2' on the room A side and the wall surface c1 'on the space C side.

  When configured in this manner, the suction cup 81 is attracted onto the wall surface a2 ′ of the wall ac ′, so that the power transmission device 71a is stably placed, and the suction cup 82 is attracted onto the wall surface c1 ′ of the wall ac ′. By doing so, since the power receiving device 74a is stably placed, it is not necessary to provide a stand and a stand base for the power transmitting device and the power receiving device. For this reason, it is possible to place the power transmission device 71a and the power reception device 74a at any location on the wall ac ', and the flexibility regarding the installation location of the power transmission device and the power reception device is improved.

  In the present embodiment, the state holding means for holding the states of the power transmission unit 11 included in the power transmission pad 76 and the power reception unit 12 included in the power reception module 3 uses magnets as in the above embodiments. It is also possible to use a fitting part, or to hold the state by suction with a suction cup. Since these state holding methods are the same as those described in the first embodiment, a detailed description thereof will be omitted.

  Further, in the present embodiment, in order to use the electronic device 5 in the space C in which no AC outlet is installed, the commercial voltage supplied to the room A adjacent to the space C is converted into the space C using the power transmitting device and the power receiving device. However, by providing a plurality of sets of power transmission devices and power reception devices, a commercial voltage can be supplied from a room other than an adjacent room.

  FIG. 15 shows a configuration example in the case where a commercial voltage is supplied from a non-adjacent room. The room B adjacent to the room A including the AC outlet 901 does not include the AC outlet, and the AC outlet is not provided in the space C adjacent to the room B on the opposite side of the room A.

  The room A is provided with a power transmission device 71 on the wall surface a3 side, and a power reception device 74 is provided on the wall surface b3 side of the opposite room B across the wall ab. A power transmission pad 76 is provided at the tip of the cord 75 of the power reception device 74, and a power reception module 83 provided in the power transmission device 71 b provided on the wall surface b 4 side of the room B is placed on the power transmission pad 76. Has been. A power receiving device 74b is provided on the wall c4 side of the space C on the opposite side across the power transmission device 71b and the wall bc. A power transmission pad 76b is provided at the tip of the cord 75b of the power reception device 74b, and the power reception module 3 included in the electronic device 5 is placed on the power transmission pad 76b. Similarly to the above-mentioned wall ac, the wall ab and the wall bc are made of a material having a low magnetic permeability such as glass and nonmetal, and the width thereof is sufficiently thin. A device that can supply power by generating magnetic coupling between the power receiving unit 12 included in the power receiving device 74 and between the power transmitting unit 11 included in the power transmitting device 71b and the power receiving unit 12 included in the power receiving device 74b. It does not matter. The power transmission device 71b is stably fixed by a stand 77b, and the power reception device 74b is stably fixed by a stand 78b.

  In such a configuration, when the AC plug 73 included in the power transmission device 71 is inserted into the insertion port 902 of the AC outlet 901, commercial voltage is supplied from the AC outlet 901 to the power transmission device 71 via the cord 72. The commercial voltage supplied to the power transmission device 71 is given to the power reception device 74 by magnetic coupling via the wall ab, and is sent to the power transmission pad 76 via the cord 75. The commercial voltage sent to the power transmission pad 76 is supplied to the power receiving module 83 placed on the power transmission pad 76 by magnetic coupling, and is supplied to the power transmission device 71b via the cord 72b. The commercial voltage supplied to the power transmission device 71b is given to the power reception device 74b by magnetic coupling via the wall bc, and is sent to the power transmission pad 76b via the cord 75b. The commercial voltage sent to the power transmission pad 76 b is supplied to the power receiving module 3 placed on the power transmission pad 76 b by magnetic coupling and supplied to the electronic device 5 via the cord 4. That is, in this embodiment, the commercial voltage is supplied from the room A that is not adjacent to the space C, and the electronic device 5 becomes available in the space C. Thus, even when separated by a plurality of partitioned spaces, it is possible to supply a commercial voltage by providing power transmission devices and power reception devices as many as the number of separated walls (this example). In this case, two sets of power transmission devices and power reception devices are required because they are separated by two walls).

  In this embodiment, both the power transmission device and the power reception device are configured to maintain stability by including a stand. However, as described above, the stand may be configured to be adjustable in height, and the wall surface may be adjusted. For example, when it is made of glass or the like and the surface roughness is reduced to such an extent that the suction cup can be attached, it may be configured so that the stand is not provided by making the suction cup suck the wall surface. .

  Also in the present embodiment, as in the first embodiment, for example, when the room A, the room B, and the space C are places where use of water is prohibited, a power transmission device, a power reception device, When power transmission pads and power reception modules are installed in places where the possibility of moisture flowing into them is clearly low, waterproofing is applied to the external surfaces of these power transmission devices, power reception devices, power transmission pads, and power reception modules. There may be no configuration.

<Fifth Embodiment>
A fifth embodiment of the present invention will be described with reference to the drawings. FIG. 16 is a conceptual diagram of the power supply system in the present embodiment. In addition, about the part same as 1st-4th embodiment, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  In the power supply system 1d shown in FIG. 16, a solar power generation system 90 is provided in the outdoor space E. The solar power generation system 90 includes a solar power generation panel 91 that generates a DC voltage by photoelectric conversion when receiving sunlight, a power conditioner 92 that converts the generated DC voltage into a commercial AC voltage, and a power conditioner 92 that converts the generated DC voltage. A cord 93 is provided for outputting the commercial voltage. Further, in the outdoor space E, a power transmission device 71 is provided on the wall surface e1 side of the wall de separating the space E and the room D, and the output of the power conditioner 92 is given to the power transmission device 71 via the cord 93. It has a configuration. In FIG. 16, the power conditioner 92 and the power transmission device 71 are directly connected by the cord 93. However, the connection form is not limited to this. For example, as shown in FIG. It is also possible to adopt a configuration in which In this case, the output (commercial voltage) of the power conditioner 92 is supplied to the power transmission pad 76 via the cord 93, and the commercial voltage is sent to the power receiving module 77 mounted on the power transmission pad 76 by magnetic coupling. The power is supplied from the module 77 to the power transmission device 71 via a cord (not shown). Further, the power transmission device 71 of FIG. 16 includes a stand 77, and this stand 77 is stably fixed by being placed on the ground of the outdoor E.

  On the other hand, in the room D adjacent to the space E, a power receiving device 74 is provided on the wall surface d1 adjacent to the space E. The power receiving device includes a power receiving unit 12 and a cord 75. A power transmission pad 76 is provided at the tip. The power transmission pad 76 includes the power transmission unit 11 inside. Further, the electronic device 5 includes a cord 4, and a power receiving module 3 having a power receiving unit 12 is provided at the tip thereof. In addition, the power receiving device 74 includes a stand 78, and this stand 78 is stably fixed by being placed on the floor surface of the room D.

  When configured in this way, the voltage generated by the solar panel 91 is converted into a commercial voltage by the power conditioner 92 and supplied to the power transmission device 71. Then, magnetic coupling occurs between the power transmission unit 11 included in the power transmission device 71 and the power reception unit 12 included in the power reception device 74 via the wall de surrounded by the wall surface e1 and the wall surface d1, and the power reception unit 12 is commercialized. Voltage is supplied. The commercial voltage supplied to the power receiving unit 12 is given to the power transmission pad 76 via the cord 75. At this time, when the power reception module 3 included in the electronic device 5 is placed on the power transmission pad 76, magnetic coupling occurs between the power transmission unit 11 included in the power transmission pad 76 and the power reception unit 12 included in the power reception module 3. A commercial voltage is supplied to the power receiving module 3, and the commercial voltage supplied to the power receiving module 3 is applied to the electronic device 5 via the cord 4, so that the electronic device 5 becomes available. Note that the principle of supplying power from the power transmitting device 71 to the power receiving device 74 and the principle of supplying power from the power transmitting pad 76 to the power receiving module 3 will be described below with respect to the power receiving module 3 from the power transmitting module 2 in the first embodiment. Since this is the same as the principle of supplying power to the device, its description is omitted. The wall de is made of a material having a low magnetic permeability such as glass or nonmetal, and the width thereof is sufficiently thin. Therefore, the wall de is between the power transmission unit 11 included in the power transmission device 71 and the power reception unit 12 included in the power reception device 74. Thus, it is possible to supply power by generating magnetic coupling.

  In the present embodiment, the state holding means for holding the states of the power transmission unit 11 included in the power transmission pad 76 and the power reception unit 12 included in the power reception module 3 uses magnets as in the above-described embodiments. It is also possible to use a fitting part, or to hold the state by suction with a suction cup. Since these state holding methods are the same as those described in the first embodiment, a detailed description thereof will be omitted.

  The power transmission device 71 includes the stand 77, and the power reception device 74 includes the stand 78. As described in the fourth embodiment, these stands include the stand base and the height of the stand. A configuration that can adjust the height may be used. In addition, when the wall de is made of, for example, glass and the surface roughness is reduced to such an extent that the suction cup can be attached, both the power transmission device 71 and the power reception device 74 are provided with suction cups. In addition, the suction cup may be configured to be stably installed by adhering to the wall surface.

  In this way, by adopting the configuration of the present embodiment, for example, even when wiring work is not completed indoors, it is possible to supply commercial voltage indoors by installing the power transmitting device and the power receiving device at appropriate locations. It becomes.

  In this embodiment, the solar power generation system is employed as the power generation method, but the present invention is not limited to this, and other power generation systems may be employed. For example, when wind power generation is adopted, instead of the solar panel 91, a blade that rotates by receiving wind, a speed increaser that increases the rotation of the blade to a constant rotational speed, and a speed increaser that lifts the blade. And a wind turbine generator (not shown) composed of a generator that generates power by rotating at a different rotational speed, and a control transformer (not shown) for converting to a commercial voltage instead of the power conditioner 92 It does not matter. Furthermore, when there is a supply spot where the commercial power source can be used in the outdoor E, a configuration may be adopted in which the power supply system is supplied from the supply spot to the power transmission device 71 without providing a power generation system.

  In the present embodiment, for example, when the room D is a room where water is prohibited, water may flow into the power receiving device 74, the power receiving module 3, and the power transmitting pad 76. In the case where the module is installed in a clearly low place, the outer surface of these modules may not be waterproofed. Similarly, when the power transmission device 71 is installed in a place with a roof or the like, and is installed in a place where the possibility of water flowing into the interior is clearly low, a waterproof treatment is applied to the outer surface of the power transmission device 71. It does not matter even if it does not apply.

  The power transmission control device 101 includes authentication means for authenticating a user, power supply means for supplying power to the user, and detection means for detecting the amount of power used by the user. At this time, the power supplied from the power conditioner 92 is not only provided to the user, but also used as a control power source inside the power transmission control device 101. At this time, since a DC power source is necessary as a control power source, the power transmission control device 101 may include a conversion unit that performs AC / DC conversion. It may be configured to be used as a control power source for the apparatus 101. In this case, the storage battery 94 and the power transmission control device 101 may be directly electrically connected.

  The power transmission control device 101 includes a power transmission pad 103 on the upper surface of the device, and includes a power transmission unit 11 therein. In addition, a watt-hour meter 104 that detects the amount of power used is provided inside the apparatus. In addition, an antenna 105 is provided inside the apparatus, and the apparatus can be connected to the network line 110 by wireless communication. The server 121 of the management company that manages the power supply service of this embodiment via the network line 110 is provided. The communication is possible.

And a display monitor 108 for transmitting instruction contents and communication items.

  When the user inserts the dedicated card 109 into the card insertion slot 106 and passes a user authentication step to be described later, the user places the power receiving module 3 at a predetermined position on the power transmitting pad 94, thereby receiving the power receiving module. The electronic device 5 is ready for use via the cord 4 connected to 3. By using the electronic device 5 for a necessary time, the user is charged according to the amount of power used measured by the watt-hour meter 104, and is charged later or withdrawn from an account or the like. . Note that the principle of supplying power from the power transmission pad 103 to the power receiving module 3 is the same as the principle of supplying power from the power transmitting module 2 to the power receiving module 3 in the first embodiment described above, and thus the description thereof is omitted. To do.

  18 is a diagram illustrating an example of a management system 120 of a management company that manages the power supply service illustrated in FIG. The management system 120 shown in FIG. 18 includes a server 121 connected to the network 110, a user authentication system 122 that is a client system connected to the server 121 and performs user authentication, and a client connected to the server 121. A charge calculation system 123 that calculates a charge based on the amount of power used by the user, and a charge request system that performs a charge request procedure for the user in response to an instruction from the charge calculation system 123 124. The charge billing system 124 may instruct the financial institution to withdraw the calculated amount given from the charge calculating system 123 from a predetermined account designated by the user at a predetermined date and time. An instruction to send transfer paper that can be transferred at a convenience store or the like may be given. The server 121, the authentication system 122, the fee calculation system 123, and the fee billing system 124 may be configured by a single server machine or the like.

  FIG. 19 is a flowchart showing a flow when the user actually uses the power supply service shown in FIG. As shown in FIG. 19, in the flowchart for receiving the power supply service of this embodiment, the user authentication step (STEP 11) for authenticating the user, and the power receiving module 3 is correctly placed on the power transmission pad 103. A power transmission availability determination step (STEP 12) that determines whether or not power transmission is possible by detecting whether or not power transmission is possible, and an energization start step (STEP 13) that actually starts energization when it is determined in STEP 12 that power transmission is possible When the user detects that the power receiving module 3 has been removed from the power transmission pad 103, an energization stop step (STEP 14) for stopping energization, and a used electric energy calculating step (STEP 15) for calculating the electric energy used by the user, A charge calculation step (ST) for calculating a charge based on the power consumption calculated in STEP 15 And P16), formed out with billing step of billing charges have been calculated by the STEP 16 (STEP 17).

  FIG. 20 is a flowchart showing in detail the user authentication step (STEP 11). First, the user inserts a dedicated card 109 individually owned into the card insertion slot 106 (STEP 11-1). The power transmission control device 101 determines whether or not the inserted card 106 is a correct card (STEP 11-2). If the card 106 is an appropriate card (Yes in STEP 11-2), the process proceeds to STEP 11-3 and the PIN number is set. Ask for input. If the card is inappropriate (No in STEP 11-2), the inserted card 109 is returned and the card is requested to be inserted again (STEP 11-1). At this time, a warning to that effect may be displayed on the display monitor 108. Note that the determination of the appropriateness of the card performed in STEP 11-2 may include a recognition unit for recognizing the dedicated card in the power transmission control device 101, and the authentication system 122 authenticates. It doesn't matter. When authentication is performed by the authentication system 122, when a dedicated card is inserted, card information is given from the antenna 105 to the server 121 via the network line 110. When the server 121 recognizes that the received information is information related to the card contents, the server 121 gives the information to the authentication system 122 and also gives an instruction for urging to determine whether the card information is appropriate. If the authentication system 122 is an appropriate card, the authentication system 122 returns a signal indicating that it is an appropriate card to the server 121, and if it is an inappropriate card, the authentication system 122 returns a signal indicating that the card is inappropriate to the server 121. . The server 121 notifies the antenna 105 via the network line 110 of the result of the authentication judgment performed by the authentication system 122, and the power transmission control device 101 gives the next instruction based on the received content. I do not care.

  If it is determined that the card entered in STEP 11-2 is appropriate, the PIN code is requested in STEP 11-3. The user inputs the personal identification number set by the key input unit 107. The power transmission control device 101 determines whether or not the input password is a correct number (STEP 11-4), and if it is an appropriate number (Yes in STEP 11-4), the next energization determination step (STEP 12). move on. If the number is inappropriate (NO in STEP 11-4), the password is requested again (STEP 11-3). At this time, the number of input of the personal identification number is counted, and if an inappropriate number is input more than a predetermined number of times, the card may be returned to return to the first step (STEP 11-1). A warning to that effect may be displayed. . Note that the authentication system 122 may authenticate the determination of the accuracy of the personal identification number performed in STEP 11-3. At this time, when the password is input, the input password is given from the antenna 105 to the server 121 via the network line 110. At this time, if the authentication system 122 does not determine the accuracy of the card in STEP 11-2, the card information is given to the server 121 together with the password. When the server 121 recognizes that the received information is information related to the personal identification number, the server 121 gives the information to the authentication system 122 and also gives an instruction for urging the user to determine whether the personal identification number is appropriate. The authentication system 122 compares the card information with the password, and if it is an appropriate password, returns a signal indicating that the password is appropriate to the server 121, and if the password is an inappropriate password Returns a signal to the server 121 indicating that the password is inappropriate. The server 121 notifies the antenna 105 via the network line 110 of the result of the authentication judgment performed by the authentication system 122, and the power transmission control device 101 gives the next instruction based on the received content. I do not care.

  FIG. 21 is a flowchart showing in detail the power transmission availability determination step (STEP 12). When the authorization of the user is completed in STEP 11, the power transmission control device 101 energizes the power transmission unit 11 provided in the power transmission pad 103 to prepare for power supply (STEP 12-1). Next, the process proceeds to a step of confirming whether or not the power receiving module 3 is placed on the power transmission pad 103 (STEP 12-2). If the power receiving module 3 can be confirmed (Yes in STEP 12-2), power transmission is started and the usage amount Is started (STEP 13). If the power receiving module 3 cannot be confirmed (No in STEP 12-2), the step of confirming the power receiving module 3 is repeated for a predetermined time until it can be confirmed (STEP 12-2). At this time, if the power receiving module 3 cannot be confirmed even after the predetermined time has elapsed, the power transmission to the power transmission unit 11 provided in the power transmission pad 103 is stopped, the card is returned, and the process returns to STEP 11. It doesn't matter. At this time, a warning to that effect may be displayed on the display monitor 108. Note that the method for confirming the power receiving module 3 is the same as the method for recognizing the power receiving unit 12 included in the power receiving module 3 as described above in the first embodiment. To do.

  When power transmission starts in STEP 13, the watt-hour meter 104 starts measuring the amount of transmitted power. This measurement is performed until power transmission ends (STEP 14). When the power transmission control device 101 cannot confirm the presence of the power receiving module 3 on the power transmission pad 103, or when the user gives an instruction to stop power transmission, or when a lightning strike or the like occurs, the power transmission is terminated. This is performed when a large voltage value is confirmed inside the control device. The power transmission stop instruction may be configured by the user using the key input unit 107.

When an instruction to end power transmission is given, the power transmission control device 101 stops power transmission to the power receiving module 3 (STEP 14), and the power meter 104 calculates the amount of power used by the user (STEP 15). The amount of power used calculated by the watt-hour meter 104 is sent from the antenna 105 to the server 121 via the network line 110. When the server 121 recognizes that the received information is information on the power consumption,
The charge calculation system 123 is instructed to calculate the charge to be charged according to the amount of power used, and the charge calculation system 121 receives this instruction and calculates the charge to be charged according to the amount of power used ( (STEP 16). When the charge calculation system 123 calculates the charge to be charged, the charge request system 124 instructs the charge request system 124 to charge the charge, and the charge request system 124 instructs to withdraw from a predetermined account designated by the user at a predetermined date and time. To a financial institution (STEP 17).

  By being configured in this way, the user can easily use the electronic device on the go by paying a fee and receiving provision of the power supply service. In the case where a notebook PC is used as the electronic device 5, it is possible to perform wireless internet using the antenna 105 included in the power transmission control device 101.

  In the above-described configuration, the solar power generation system is adopted as the power supply source. I do not care. In the latter case, particularly when the service company providing the power supply service is not a power company, a charge corresponding to the amount of power used may be paid to the power company receiving the supply.

  Moreover, the state holding means for holding the states of the power transmission unit 11 included in the power transmission pad 103 and the power reception unit 12 included in the power reception module 3 may use magnets as in the above embodiments. A fitting portion may be used, or the state may be maintained by suction with a suction cup. Since these state holding methods are the same as those described in the first embodiment, a detailed description thereof will be omitted. Furthermore, the configuration of the power transmission control device 101 and the configuration of the management system 120 are merely examples, and are not limited to the above-described configuration.

  Further, in the present embodiment, the power transmission control device 101 may be installed in a physically separated place in a state where it is electrically connected to the solar power generation system or the wind power generation system. In this case, if the possibility that water will flow into the interior is obviously low, such as when the power transmission control apparatus 101 is installed indoors where use of water is prohibited, the outside of the power transmission control apparatus 101 The surface may not be waterproofed.

<Seventh Embodiment>
A seventh embodiment of the present invention will be described with reference to the drawings. FIG. 22 is a conceptual diagram of the power supply system in the present embodiment. In addition, about the part same as each 1st-6th embodiment, the same code | symbol is attached | subjected and the detailed description is abbreviate | omitted.

  The power supply system 1f of the present embodiment shown in FIG. 22 includes a power transmission sheet 131 that is miniaturized and portable, a power reception pad 133 that is miniaturized and portable, and a cord that connects the power reception pad 133 and the electronic device 5 134. The power transmission sheet 131 includes a solar cell panel 132 that generates a DC voltage when receiving sunlight, a DC / AC conversion unit (not shown) that converts the DC voltage generated by the solar cell panel 132 into a commercial voltage, The unit 11 is provided inside. The power receiving pad 133 includes the power receiving unit 12 therein.

  When configured in this manner, the power transmission sheet 131 is installed outdoors, and the power reception pad 133 is placed on the power transmission sheet 131, whereby the voltage generated in the solar cell panel 132 included in the power transmission sheet 131 is changed to the power transmission unit 11. The power is supplied from the power transmission unit 11 to the power reception unit 12 included in the power reception pad 133. At this time, by electrically connecting the power receiving pad 133 and the electronic device 5 with the cord 134, power is supplied to the electronic device 5 and the electronic device 5 becomes available.

  Therefore, according to the present embodiment, the power transmission sheet 131 is reduced to a portable size, the solar cell panel 132 is provided therein, and the power receiving pad 133 is also reduced to a portable size. As long as the solar cell panel 132 can receive sunlight by carrying the power transmission sheet 131, the power receiving pad 133, and the cord 134, the electronic device 5 can be used at any location. At this time, the cord 134 may be an independent cord that is not attached to either the power receiving pad 133 or the electronic device 5, or may be attached to either one of them in advance.

  Further, in each of the embodiments described above, the power transmission unit 11 and the power reception unit 12 are configured to improve power transmission efficiency by arranging them at appropriate positions using the state holding unit. As an example, the power transmission unit 11 and the power reception unit 12 may include a plurality of coils, and may include a selection unit that selects a combination having the highest power transmission efficiency among these. This configuration will be described below with reference to the drawings. FIG. 23 is a block diagram illustrating a configuration when the power transmission unit 11 and the power reception unit 12 include a plurality of coils. Since the other components are the same as those in FIG. 3, the illustration is omitted to avoid complication.

  A power transmission unit 11a illustrated in FIG. 23 includes three primary power coils 22a, 22b, and 22c instead of the power primary coil 22 included in the power transmission unit 11 illustrated in FIG. 23 includes three power secondary coils 41a, 41b, and 41c instead of the power secondary coil 41 included in the power receiving unit 12 illustrated in FIG. In the following, the number of the primary coil for power and the secondary coil for power is assumed to be 3 as shown in FIG. 23, but this number is not limited to 3.

  The power primary coils 22a, 22b, and 22c include switching elements S11, S12, and S13, respectively, and are configured such that the coils to be used are selected by being on / off controlled by the power transmission switch control unit 141. For example, when the primary side coil 22a is used, the switching element S11 is turned on by the control signal from the power transmission switch control unit 141, the switching elements S12 and S13 are turned off, and the primary side coil 22a in the on state is turned on. On the other hand, a commercial voltage is applied through the switching element 21. Note that the switching elements S11, S12, and S13 may each be constituted by a transistor or other switching elements such as a MOSFET. Further, the drive power source of the power transmission switch control unit 141 may use a DC voltage Vcc that is an internal power source of the power transmission control IC 23 in the power transmission unit 11.

  On the other hand, the power secondary coils 41a, 41b, and 41c include switching elements S21, S22, and S23, respectively, and are configured such that the coils to be used are selected by being on / off controlled by the power receiving switch control unit 142. . For example, when the secondary side coil 41a is used, the switching element S21 is turned on and the switching elements S22 and S23 are turned off by the control signal from the power receiving switch control unit 142, and the primary side coil 41a in the on state is turned on. On the other hand, a voltage is induced at both ends of the coil 41a by magnetic coupling that occurs between the power primary coil employed in the power transmission unit 11a. The power receiving unit 12 a includes a voltage measuring unit 143 that measures the induced voltage, and a voltage value measured by the voltage measuring unit 143 is provided to the power receiving switch control unit 142. The power receiving unit 12a has a switching element S24, and is connected to a line L1, which is a connection line to which the voltage measuring unit 143 is connected, in order to measure the voltage induced at both ends of the coil by the voltage measuring unit 143. In order to supply the voltage induced at both ends of the coil to the electronic device 5, switching is performed between the case where the electronic device 5 is connected to the line L <b> 2 that is a connection line to which the electronic device 5 is connected. This switching control is performed according to a control signal given from the power receiving switch control unit 142. The power receiving switch control unit 142 provides a control signal to the power transmission switch control unit 141 via the signal secondary coil 42 and the signal primary coil 29 (not shown in FIG. 23) shown in FIG. It has become.

  When configured in this way, first, the power transmission switch control unit 141 turns on the switching element S11, and the power reception switch control unit 142 turns on the switching element S21. At this time, a commercial voltage is applied to the coil 22a, and a voltage is induced in the coil 41a by magnetic coupling between the coil 22a and the coil 41a. The switching element S24 is connected to the line L1, and a voltage induced in the coil 41a is given to the voltage measuring unit 143, and the voltage measuring unit 143 measures this voltage. The measured voltage value is given to the power receiving switch control unit 142, and this value is stored in the power receiving switch control unit 142 together with the combination of the coils in the ON state (in this case, the combination of the coil 22a and the coil 41a).

  When the power receiving switch control unit 142 stores the voltage value data, the power receiving switch control unit 142 switches the power primary coil to the power transmission switch control unit 141 via the signal secondary coil 42 and the signal primary coil 29. Give the control signal to instruct. The power transmission switch control unit 141 turns off the switching element S11 and turns on the switching element S12 to measure the voltage induced in the power secondary coil by the magnetic coupling between the coil 22b and the coil 41a. Transition. When this step is completed, the process proceeds to a step of measuring a voltage induced in the power secondary coil by the magnetic coupling between the coil 22c and the coil 41a. When the measurement up to the voltage induced in the power secondary coil by the magnetic coupling between the coil 22c and the coil 41a is completed, the power receiving switch control unit 142 turns off the switching element S21 and turns on the switching element S22. An instruction to use the secondary coil 41b is given.

  As described above, based on the control signal from the power receiving switch control unit 142, the secondary induced voltage in all combinations of the power primary coil included in the power transmitting unit 11a and the power secondary coil included in the power receiving unit 12a. When the measurement is completed, a control signal is given to each switching element so as to realize a combination in which the highest value among the voltage values stored in the power receiving switch control unit 142 is realized, and the coil is switched. Then, the power receiving switch control unit 142 gives a control signal to the effect that the switching element 24 is connected to the line L2, and the switching element 24 receives this control signal and switches to the connection to the line L2, so that the combination of the coils A voltage induced in the secondary coil for power is supplied to the electronic device 5.

  By configuring in this way, it is possible to select a combination of coils having high power transmission efficiency even when a slight deviation occurs in the installation position of the power transmission module including the power transmission unit 11a and the power reception module including the power reception unit 12a. The desired power can be supplied to the electronic device 5. In the above description, the coil combination that has measured the highest voltage value among the voltage values measured by the power receiving switch control unit 142 is selected. However, a combination that is closest to the commercial voltage value may be selected. Further, in each of the embodiments described above, the turn ratio of the voltage coil is set to 1: 1, but the turn ratio is variable and can be controlled by a control signal from the power receiving switch control unit 142. A configuration may be adopted in which a value closest to the commercial voltage value is induced on the secondary side by changing the turns ratio. In this case, the voltage close to the commercial voltage may be generated by changing only the transformation ratio, or the voltage close to the commercial voltage may be generated together with the selection control of the combination of the coils described above.

  In the above description, it is assumed that there are a plurality of power primary side coils and power secondary side coils, but one of the primary side coil and the secondary side coil is It may be configured by a plurality of coils.

  Further, with this configuration, even when the user uses an AC voltage other than the commercial voltage, by selecting the combination of coils that is closest to the desired voltage value, the user can use it not only at the commercial voltage.
