図6に示すように、上ケース2及び下ケース3によって形成される内部空間には、基板4、基板4上に設けられた充電用回路部品、及びファン15が設けられる。充電用回路部品は、FET等のスイッチング素子21、フォトカプラ22、トランス23、ダイオード24、及び放熱フィン25〜27等を含む。ファン15は、軸流ファンであって、下方から空気を吸い込んで上方に送り出すように、上ケース2のリブ13によって電池パック装着部2aの直下に保持される。基板4及びそれに設けられた充電用回路部品は、風窓6と風窓7との間を避けた位置に設けられる。ファン15の下方の空間と基板4の収容空間との間は、風窓7から浸入した水等の液体が基板4の収容空間に流出しないように、下ケース3のリブ14によって仕切られる。 As shown in FIG. 6, in the internal space formed by the upper case 2 and the lower case 3, the substrate 4, the charging circuit component provided on the substrate 4, and the fan 15 are provided. The charging circuit component includes a switching element 21 such as an FET, a photocoupler 22, a transformer 23, a diode 24, and heat radiation fins 25 to 27 and the like. The fan 15 is an axial fan, and is held directly under the battery pack mounting portion 2a by the rib 13 of the upper case 2 so as to suck air from below and send it upward. The substrate 4 and the charging circuit components provided therein are provided at positions avoiding between the wind window 6 and the wind window 7. The space below the fan 15 and the storage space of the substrate 4 are partitioned by ribs 14 of the lower case 3 so that liquid such as water that has entered through the wind window 7 does not flow out into the storage space of the substrate 4.

ファン15の発生する気流は、第1気流k1及び第2気流k2を含む。第1気流k1は、風窓6から吸い込まれ、基板4上の充電用回路部品を通らずに風窓7に向かって流れ、風窓7から排気される。第2気流k2は、風窓8から吸い込まれ、基板4上の充電用回路部品を通り(充電用回路部品を冷却し)、ファン15の吸込み側において第1気流k1と合流して風窓7に向かって流れ、風窓7から排気される。風窓7から排気された第1気流k1及び第2気流k2は、電池パック5の風窓5aから電池パック5内に入り、電池パック5内の電池セル等を冷却し、風窓5bから排気される。 The airflow generated by the fan 15 includes a first airflow k1 and a second airflow k2. The first air flow k1 is sucked from the wind window 6, flows toward the wind window 7 without passing through the charging circuit component on the substrate 4, and is exhausted from the wind window 7. The second airflow k2 is sucked from the airflow window 8, passes through the charging circuit component on the substrate 4 (cools the charging circuit component), joins the first airflow k1 on the suction side of the fan 15, and heads for the airflow window 7. And is exhausted from the wind window 7. The first airflow k1 and the second airflow k2 exhausted from the wind window 7 enter the battery pack 5 through the wind window 5a of the battery pack 5, cool the battery cells and the like in the battery pack 5, and are exhausted from the wind window 5b.

本実施の形態によれば、下記の効果を奏することができる。 According to this embodiment, the following effects can be obtained.

(1) 基板4上の充電用回路部品を第2気流k2により冷却しつつ、充電用回路部品を冷却していない第1気流k1を第2気流k2と合流させて電池パック5の冷却に利用するため、充電用回路部品を冷却した後の気流のみで電池パック5を冷却する場合と比較して、電池パック5の冷却効率を高めることができる。 (1) While the charging circuit component on the substrate 4 is cooled by the second airflow k2, the first airflow k1 that has not cooled the charging circuit component is merged with the second airflow k2 and used for cooling the battery pack 5. Therefore, the cooling efficiency of the battery pack 5 can be improved as compared with the case where the battery pack 5 is cooled only by the air flow after cooling the charging circuit component.

(2) 第1気流k1及び第2気流k2を単一のファン15で発生させるため、部品点数が少なくコスト安であり、また小型化に有利である。 (2) Since the first airflow k1 and the second airflow k2 are generated by a single fan 15, the number of parts is small, the cost is low, and it is advantageous for miniaturization.

(3) 電池パック5を装着していない状態で風窓7から水等の液体が入り込んでも、風窓6から排水でき、防水面でも優れている。 (3) Even if a liquid such as water enters through the wind window 7 without the battery pack 5 attached, it can be drained from the wind window 6 and is excellent in terms of waterproofing.

実施の形態2 図7は、本発明の実施の形態2に係る充電装置1Bに電池パック5を装着した状態の正断面図である。図8は、同状態の右側断面図である。なお、図8において、風窓5bは、簡易的に1つのみを大きく示している。以下、実施の形態1との相違点を中心に説明する。ファン15は、上方から空気を吸い込んで下方に送り出すように、下ケース3によって電池パック装着部2aの下方かつ風窓6の真上に保持される。ファン16は、軸流ファンであって、図7中の右方(風窓7の下方の空間)から空気を吸い込んで左方(基板4及び充電用回路部品側)に送り出すように、下ケース3によって電池パック装着部2aの下方に保持される。風窓8は、自身とファン16との間の風路に基板4上の充電用回路部品が存在する位置に開口する。本実施の形態では、電池パック5の風窓5aは排気口であり、風窓5bは吸気口である。また、充電装置1Bの風窓6は第1排気口であり、風窓7は吸気口であり、風窓8は第2排気口である。 Embodiment 2 FIG. 7 is a front sectional view in a state where the battery pack 5 is attached to the charging device 1B according to the second embodiment of the present invention. FIG. 8 is a cross-sectional view on the right side in the same state. In addition, in FIG. 8, only one wind window 5b is simply shown large. Hereinafter, the differences from the first embodiment will be mainly described. The fan 15 is held below the battery pack mounting portion 2a and directly above the wind window 6 by the lower case 3 so as to suck air from above and send it downward. The fan 16 is an axial fan, and the lower case 3 is such that air is sucked from the right side (space below the wind window 7) in FIG. 7 and sent out to the left side (board 4 and charging circuit component side). Is held below the battery pack mounting portion 2a. The wind window 8 opens at a position where a charging circuit component on the substrate 4 exists in the air passage between itself and the fan 16. In the present embodiment, the air window 5a of the battery pack 5 is an exhaust port, and the air window 5b is an intake port. Further, the air window 6 of the charging device 1B is a first exhaust port, the air window 7 is an intake port, and the air window 8 is a second exhaust port.

ファン15及びファン16は、第1気流k1及び第2気流k2を発生する。第1気流k1は、風窓7から吸い込まれ、基板4上の充電用回路部品を通らずに風窓6に向かって流れ、風窓6から排気される。第2気流k2は、風窓7から吸い込まれ、第1気流k1から分岐し、基板4上の充電用回路部品を通り(充電用回路部品を冷却し)、風窓8に向かって流れ、風窓8から排気される。第1気流k1及び第2気流k2は、図8に示すように、風窓7から吸い込まれる前に、電池パック5の風窓5bから電池パック5内に吸い込まれ、電池パック5内の電池セル5c等を冷却し、風窓5aから排気され、風窓7から充電装置1B内に吸い込まれる。 The fan 15 and the fan 16 generate a first airflow k1 and a second airflow k2. The first air flow k1 is sucked from the wind window 7, flows toward the wind window 6 without passing through the charging circuit component on the substrate 4, and is exhausted from the wind window 6. The second air flow k2 is sucked from the wind window 7, branches from the first air flow k1, passes through the charging circuit component on the substrate 4 (cools the charging circuit component), flows toward the wind window 8, and flows from the wind window 8. It is exhausted. As shown in FIG. 8, the first air flow k1 and the second air flow k2 are sucked into the battery pack 5 from the wind window 5b of the battery pack 5 before being sucked from the wind window 7, and the battery cells 5c and the like in the battery pack 5 and the like. Is cooled, exhausted from the air window 5a, and sucked into the charging device 1B from the air window 7.

本実施の形態によれば、2つのファン15,16によって発生した強力かつ新鮮な気流で電池パック5を冷却するため、電池パック5の冷却効率が高められる。また、電池パック5を冷却後の第2気流k2によって基板4上の充電用回路部品も冷却するため、充電用回路部品の発熱にも好適に対処できる。また、防水面では実施の形態1と同様の効果を奏することができる。 According to the present embodiment, since the battery pack 5 is cooled by the strong and fresh airflow generated by the two fans 15 and 16, the cooling efficiency of the battery pack 5 is improved. Further, since the charging circuit component on the substrate 4 is also cooled by the second air flow k2 after cooling the battery pack 5, the heat generation of the charging circuit component can be suitably dealt with. Further, in terms of waterproofing, the same effect as that of the first embodiment can be obtained.

実施の形態3 図9は、本発明の実施の形態3に係る充電装置1Cに電池パック5を装着した状態の正断面図である。充電装置1Cは、図7に示した実施の形態2の充電装置1Bからファン15を無くしたものに相当する。本実施の形態では、風窓6は第1吸気口であり、風窓7は第2吸気口であり、風窓8は排気口である。ファン16は、第1気流k1及び第2気流k2を発生する。第1気流k1は、風窓7から吸い込まれ、基板4上の充電用回路部品を通り(充電用回路部品を冷却し)、風窓8に向かって流れ、風窓8から排気される。第1気流k1は、風窓7から吸い込まれる前に、実施の形態2(図8)と同様に、電池パック5を冷却する。第2気流k2は、風窓6から吸い込まれ、ファン16の吸込み側(風窓7の下方の空間)で第1気流k1と合流し、基板4上の充電用回路部品を通り(充電用回路部品を冷却し)、風窓8に向かって流れ、風窓8から排気される。 Embodiment 3 FIG. 9 is a front sectional view of a state in which the battery pack 5 is attached to the charging device 1C according to the third embodiment of the present invention. The charging device 1C corresponds to the charging device 1B of the second embodiment shown in FIG. 7 without the fan 15. In the present embodiment, the wind window 6 is a first intake port, the wind window 7 is a second intake port, and the wind window 8 is an exhaust port. The fan 16 generates a first airflow k1 and a second airflow k2. The first air flow k1 is sucked from the wind window 7, passes through the charging circuit component on the substrate 4 (cools the charging circuit component), flows toward the wind window 8, and is exhausted from the wind window 8. The first air flow k1 cools the battery pack 5 in the same manner as in the second embodiment (FIG. 8) before being sucked from the wind window 7. The second airflow k2 is sucked from the wind window 6, merges with the first airflow k1 on the suction side of the fan 16 (the space below the wind window 7), passes through the charging circuit component on the substrate 4, and passes through the charging circuit component (charging circuit component). (Cool), it flows toward the wind window 8, and is exhausted from the wind window 8.

本実施の形態によれば、第1気流k1によって電池パック5を冷却しつつ、電池パック5を冷却していない第2気流k2を第1気流k1と合流させて基板4上の充電用回路部品の冷却に利用するため、電池パック5を冷却した後の気流のみで充電用回路部品を冷却する場合と比較して、充電用回路部品の冷却効率を高めることができる。また、第1気流k1及び第2気流k2を単一のファン16で発生させるため、実施の形態1と同様に、部品点数が少なくコスト安であり、小型化に有利である。また、防水面においても実施の形態1と同様の効果を奏することができる。 According to the present embodiment, while the battery pack 5 is cooled by the first airflow k1, the second airflow k2 that has not cooled the battery pack 5 is merged with the first airflow k1 to join the charging circuit component on the substrate 4. Since it is used for cooling the battery pack 5, the cooling efficiency of the charging circuit component can be improved as compared with the case where the charging circuit component is cooled only by the airflow after cooling the battery pack 5. Further, since the first airflow k1 and the second airflow k2 are generated by a single fan 16, the number of parts is small and the cost is low, which is advantageous for miniaturization, as in the first embodiment. Further, the same effect as that of the first embodiment can be obtained on the waterproof surface.

According to the present embodiment, since the number of fans is two, the number of parts is increased as compared with the third embodiment, but the air volume of the cooling air can be increased. Further, since the air window 9 serving as an exhaust port is provided in the upper part of the charging device 1D, the upper part of the charging circuit component can be cooled intensively.
