A type of charger can be provided.

以下、図１から図３を参照して、本発明に係る充電器を詳細に説明する。なお、同一部位や矢印などは同一符号をもって示し、重複した説明を省略する。   Hereinafter, the charger according to the present invention will be described in detail with reference to FIGS. 1 to 3. In addition, the same site | part, an arrow, etc. are shown with the same code | symbol, and the overlapping description is abbreviate | omitted.

図１は本発明に係る充電器の概略構造図であり、図１（ａ）が概略斜視図、図１（ｂ）が小型携帯装置と接続した状態の概略斜視図である。   1A and 1B are schematic structural views of a charger according to the present invention, in which FIG. 1A is a schematic perspective view, and FIG. 1B is a schematic perspective view in a state of being connected to a small portable device.

図１において、この実施形態に係る充電器１０は、直方体を基調とする充電器本体１１と、この充電器本体１１の上面に形成された凹状の取付部１２と、取付部１２に設けられた第１接続端子６０（図２参照）と、充電器本体１１の背面１４に設けられた電源プラグ２０と燃料投入部（図示省略）と、充電器本体１１の側面１５に設けられた図示しない排気穴とを備えるとともに、小型携帯装置１よりも一回り程度大きな外観形状を備えている。   In FIG. 1, a charger 10 according to this embodiment is provided in a charger main body 11 based on a rectangular parallelepiped, a concave attachment portion 12 formed on the upper surface of the charger main body 11, and the attachment portion 12. A first connection terminal 60 (see FIG. 2), a power plug 20 provided on the back surface 14 of the charger main body 11 and a fuel input portion (not shown), and an exhaust gas (not shown) provided on the side surface 15 of the charger main body 11. It has a hole and an appearance shape that is slightly larger than the small portable device 1.

取付部１２は、小型携帯装置１が半分程度隠れるほどの深さを有しており、この取付部１２に小型携帯装置１を取り付けることにより、充電器本体１１に設けられた第１接続端子６０と、小型携帯装置１の背面に設けられた図示しない第２接続端子とが接触し、小型携帯装置１に収納されたバッテリーの充電を行うようになっている。   The attachment portion 12 has a depth that the small portable device 1 is hidden by about half, and the first connection terminal 60 provided in the charger main body 11 by attaching the small portable device 1 to the attachment portion 12. And a second connection terminal (not shown) provided on the back surface of the small portable device 1 comes into contact with each other, and the battery stored in the small portable device 1 is charged.

この充電器１０の大きな特徴は、小型携帯装置１と充電器１０との接触に伴って、電源プラグ２０とＡＣ電源等の外部電源との接続状態をセンサ４０（図２参照）で検出し、検出した電源プラグ２０とＡＣ電源との接続状態により、小型携帯装置１に収納されたバッテリーの充電を行うための電源として、ＡＣ電源から電力供給を受けるＡＣ／ＤＣコンバータ８０（第１発電部）あるいは燃料電池（第２発電部）を選択し、選択した発電部から供給される電力によりバッテリーの充電を行うように制御する点にある。   A major feature of the charger 10 is that a sensor 40 (see FIG. 2) detects a connection state between the power plug 20 and an external power source such as an AC power source when the small portable device 1 and the charger 10 are in contact with each other.

The charger 10 is controlled so as to charge the battery.

このような構成とすることにより、充電環境に合わせて適切な発電機を選択して電力を供給することができるので、ＡＣ電源からの電力供給が得られる場所に加えて、外出先や移動中でも手軽にバッテリーを充電することができる使い勝手の良好な充電器とすることができる。   By adopting such a configuration, it is possible to supply power by selecting an appropriate generator according to the charging environment, so that in addition to a place where power supply from an AC power source can be obtained, even while going out or on the move It is possible to provide a battery charger that is easy to use and can easily charge the battery.

次に、図２を参照して、本発明に係る充電器の内部レイアウトについて説明する。図２は本願発明に係る充電器の内部レイアウト図である。   Next, an internal layout of the charger according to the present invention will be described with reference to FIG. FIG. 2 is an internal layout diagram of the charger according to the present invention.

図２において、充電器１０は、この充電器１０の動作を統括的に制御する制御部５０と、小型携帯装置１の充電端子（第２接続端子）と接触する第１接続端子６０と、充電を行うための電力を発電する燃料電池７０と、電源プラグ２０の接続状態を検出するセンサ４０と、ＡＣ電源をＤＣ電源に変換するＡＣ／ＤＣコンバータ８０とを内部に備えている。また、充電器１０の外部には、燃料電池７０の燃料を投入する図示しない燃料投入口と、燃料電池７０から発生した水分を排気するための図示しない排気穴とを備えている。   In FIG. 2, the charger 10 includes a control unit 50 that comprehensively controls the operation of the charger 10, a first connection terminal 60 that contacts a charging terminal (second connection terminal) of the small mobile device 1, and charging. A fuel cell 70 for generating electric power for performing power, a sensor 40 for detecting the connection state of the power plug 20, and an AC / DC converter 80 for converting AC power into DC power are provided. Further, outside the charger 10 is provided with a fuel input port (not shown) for supplying fuel of the fuel cell 70 and an exhaust hole (not shown) for exhausting moisture generated from the fuel cell 70.

燃料電池７０は、発電素子７１とこの発電素子７１に燃料を供給する燃料供給部７２と、燃料供給部７２から供給される燃料を制御するガバナ７３とから構成されている。なお、この実施形態では、燃料供給部７２の一例として、メタノール等の燃料が充填された燃料カートリッジ７２ａを使用している。   The fuel cell 70 includes a power generation element 71, a fuel supply unit 72 that supplies fuel to the power generation element 71, and a governor 73 that controls the fuel supplied from the fuel supply unit 72. In this embodiment, as an example of the fuel supply unit 72, a fuel cartridge 72a filled with a fuel such as methanol is used.

燃料カートリッジ７２ａは、透明な樹脂材料で形成され、周囲から燃料の残量が確認できるようになっている。この燃料カートリッジ７２ａの先端部には図示しないガバナ取付部が形成されている。このガバナ取付部は、先端部から突出して形成されるとともに、図示しないストッパが設けてあり、このストッパがガバナ７３に取り付けられることで、ガバナ取付部が内部に押し返されて燃料がガバナ７３に供給されるようになっている。また、燃料カートリッジ７２ａは、充電器１０の背面１４に設けられた燃料投入口から投入され、図示しないカートリッジ収納部を介して充電器１０に対して着脱可能に設けられている。   The fuel cartridge 72a is formed of a transparent resin material so that the remaining amount of fuel can be confirmed from the surroundings. A governor mounting portion (not shown) is formed at the tip of the fuel cartridge 72a. The governor mounting portion is formed so as to protrude from the tip portion, and is provided with a stopper (not shown). By attaching this stopper to the governor 73, the governor mounting portion is pushed back into the governor 73 so that the fuel is fed to the governor 73. It comes to be supplied. Further, the fuel cartridge 72a is inserted from a fuel inlet provided on the back surface 14 of the charger 10, and is detachably attached to the charger 10 via a cartridge housing portion (not shown).

ガバナ７３は、燃料カートリッジ７２ａから供給される燃料を発電素子７１に適量供給する機能を備えている。このガバナ７３には、前記ガバナ取付部と嵌合する図示しない取付口が設けられており、このガバナ取付部と取付口とを押し付けた状態で所定の方向に回転させれば、ガバナ７３と燃料カートリッジ７２ａが固定されるようになっている。一方、燃料カートリッジ７２ａを取り外す場合は、燃料カートリッジ７２ａの逆の方向に回転させることで、ガバナ取付部と取付口が外れて、燃料カートリッジ７２ａがカートリッジ収納部から押し出される。利用者は充電器１０から顔を出した燃料カートリッジ７２ａを摘んで取り出すことができる。なお、前記燃料カートリッジ７２ａの着脱構造は、前記構造に限定するものではない。   The governor 73 has a function of supplying an appropriate amount of fuel supplied from the fuel cartridge 72 a to the power generation element 71. The governor 73 is provided with an attachment port (not shown) that fits into the governor attachment portion. When the governor attachment portion and the attachment port are pressed and rotated in a predetermined direction, the governor 73 and the fuel are provided. The cartridge 72a is fixed. On the other hand, when removing the fuel cartridge 72a, the governor mounting portion and the mounting port are removed by rotating in the opposite direction of the fuel cartridge 72a, and the fuel cartridge 72a is pushed out from the cartridge housing portion. The user can pick up and take out the fuel cartridge 72a that is exposed from the charger 10. The attachment / detachment structure of the fuel cartridge 72a is not limited to the above structure.

次に、図３を参照して、本願発明に係る充電器の動作フローについて説明する。図３は本願発明に係る充電器の動作フローを示す図である。   Next, the operation flow of the charger according to the present invention will be described with reference to FIG. FIG. 3 is a diagram showing an operation flow of the charger according to the present invention.

図３において、充電器１０に小型携帯装置１をセットすると（ステップ３００）と、小型携帯装置１に設けられた第２接続端子と充電器１０に設けられた第１接続端子６０が接触し、充電待機状態となる（ステップ３０１）。   In FIG. 3, when the small portable device 1 is set on the charger 10 (step 300), the second connection terminal provided on the small portable device 1 and the first connection terminal 60 provided on the charger 10 come into contact with each other. A charging standby state is entered (step 301).

第１接続端子６０と第２接続端子との接続に伴い、制御部５０は、小型携帯装置１に収納されたバッテリーの充電が必要か否かを判断し（ステップ３０２）、充電が不要な場合には充電を行わないように制御する（ステップ３１０）。   When the first connection terminal 60 and the second connection terminal are connected, the control unit 50 determines whether or not the battery stored in the small mobile device 1 needs to be charged (step 302). Is controlled not to be charged (step 310).

ステップ３０２において、小型携帯装置１に収納されたバッテリーの充電が必要な場合、制御部５０はセンサ４０を制御し、電源プラグ２０の接続状態を検知する（ステップ３０３）。   In step 302, if the battery stored in the small portable device 1 needs to be charged, the control unit 50 controls the sensor 40 to detect the connection state of the power plug 20 (step 303).

ステップ３０３において、センサ４０が充電器１０とＡＣ電源、例えば、電源プラグ２０と家庭用コンセントが接続されていると検知した場合、制御部５０は、ＡＣ電源から供給される電力により、第１接続端子６０と第２接続端子とを介して小型携帯装置１に収納されたバッテリーの充電を行うように制御する（ステップ３０４）。   In step 303, when the sensor 40 detects that the charger 10 and the AC power source, for example, the power plug 20 and the household outlet are connected, the control unit 50 uses the power supplied from the AC power source to perform the first connection. Control is performed such that the battery stored in the small portable device 1 is charged via the terminal 60 and the second connection terminal (step 304).

一方、ステップ３０３において、センサ４０が電源プラグ２０と家庭用コンセントが接続されていないと検知した場合、制御部５０は、燃料電池７０により発電を行うように制御し、発電された電力により第１接続端子６０と第２接続端子とを介してバッテリーの充電を行うようになっている。（ステップ３０５）。   On the other hand, when the sensor 40 detects in step 303 that the power plug 20 and the household outlet are not connected, the control unit 50 controls the fuel cell 70 to generate power, and the first power is generated by the generated power. The battery is charged via the connection terminal 60 and the second connection terminal. (Step 305).

ステップ３０５において、燃料電池７０による発電は、メタノールなどの燃料が充填された燃料カートリッジ７２ａから、ガバナ７３を介して発電素子７１に燃料を供給することにより発電が行われる。そして、制御部５０は、発電された電力を第１接続端子６０と第２接続端子とを介して小型携帯装置１に収納されたバッテリーの充電を行うように充電器１０を制御する。また、発電に伴って生じた水分は、充電器１０の側面１５に設けられた排気穴から放出されるようになっている。   In step 305, power generation by the fuel cell 70 is performed by supplying fuel from the fuel cartridge 72 a filled with fuel such as methanol to the power generation element 71 via the governor 73. And the control part 50 controls the charger 10 so that the battery accommodated in the small portable apparatus 1 may be charged with the generated electric power via the first connection terminal 60 and the second connection terminal. In addition, moisture generated by power generation is released from an exhaust hole provided in the side surface 15 of the charger 10.

そして、バッテリーの充電が終了したら、制御部５０は充電器１０の電源をオフして、充電作業を終了するようになっている（ステップ３０６）。   When the charging of the battery is completed, the control unit 50 turns off the power supply of the charger 10 and ends the charging operation (step 306).

このように、この実施形態に係る充電器１０によれば、ＡＣ電源による電力が得られない状態でも小型携帯装置１に収納されたバッテリーの充電を行うことができる使い勝手の良い充電器とすることができる。特に、燃料電池７０により発電を行う場合には、発電に伴って発生した水分を充電器１０の側面１５に設けられた排気穴から排気するので、小型携帯装置１に水分が付着するのを軽減することが可能となる。   As described above, according to the charger 10 according to this embodiment, the battery charger stored in the small mobile device 1 can be charged even when power from the AC power source cannot be obtained. Can do. In particular, when power is generated by the fuel cell 70, the moisture generated by the power generation is exhausted from the exhaust hole provided in the side surface 15 of the charger 10, so that the moisture is prevented from adhering to the small portable device 1. It becomes possible to do.

なお、この実施形態では、燃料電池７０への燃料供給を燃料カートリッジ７２ａにより行っているが、これに限定されるものではない。例えば、燃料供給部７２に燃料を直接注入することにより、燃料を供給するようにしても良い。   In this embodiment, the fuel supply to the fuel cell 70 is performed by the fuel cartridge 72a. However, the present invention is not limited to this. For example, the fuel may be supplied by directly injecting the fuel into the fuel supply unit 72.
