Description

【考案の詳細な説明】[Detailed description of the device]

【０００１】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、発熱部品を内蔵する本体ケースの上面に通風口を形成した電気機器 に関するものであり、特に、屋外で使用される充電装置や電源装置に用いて好適 である。 The present invention relates to an electric device in which a ventilation port is formed on an upper surface of a main body case that houses a heat-generating component, and is particularly suitable for a charging device and a power supply device used outdoors.

【０００２】[0002]

【従来の技術】[Prior art]

発熱部品を内蔵する本体ケースの上面に通風口を形成した電気機器、例えば、 充電装置や電源装置にあっては、内蔵する発熱部品の熱を本体ケース外に放出す る必要がある。そのために、本体ケースには、通常通風口が形成される。 In the case of an electric device, such as a charging device or a power supply device, in which a ventilation hole is formed on the upper surface of the main body case that houses the heat generating component, it is necessary to release the heat of the heat generating component that is built into the main body case. Therefore, a ventilation port is usually formed in the main body case.

【０００３】 ところで、電動工具等の二次電池用の充電装置やポータブルの電源装置におい ては、屋外で使用される場合が多い。そうした場合、充電装置や電源装置に形成 されている通風口を経て、本体ケース内部に雨水等の水滴が浸入し、内部の電気 回路に損傷を与える恐れがある。By the way, in many cases, a charging device for a secondary battery such as an electric tool or a portable power supply device is used outdoors. In such a case, water droplets such as rainwater may enter the inside of the main body case through the ventilation openings formed in the charging device and the power supply device, and may damage the internal electric circuits.

【０００４】[0004]

【考案が解決しようとする課題】[Problems to be solved by the device]

本考案は、斯る点に鑑みて成されたものであり、通風口を経て本体ケースに雨 水等の水滴が浸入することを抑制し、内部の電気回路の損傷を防止するものであ る。 The present invention has been made in view of the above point, and is intended to prevent water droplets such as rainwater from entering the main body case through the ventilation port and prevent damage to the internal electric circuit. .

【０００５】[0005]

【課題を解決するための手段】[Means for Solving the Problems]

本考案は、発熱部品を内蔵する本体ケースの上面に通風口を形成した電気機器 において、前記通風口は、前記本体ケースの上面から側面まで延在して設けられ た溝の側壁に開口形成されると共に、前記溝の底壁は前記側面に向かって下り傾 斜となっていることを特徴としている。 The present invention relates to an electric device in which a ventilation opening is formed on an upper surface of a main body case containing a heat-generating component, the ventilation opening being formed in a side wall of a groove extending from an upper surface to a side surface of the main body case. In addition, the bottom wall of the groove is inclined downward toward the side surface.

【０００６】[0006]

【作用】 電気機器の本体ケースの上面の水滴は、ケースの上面から側面まで下り傾斜で 延在する溝に沿って側面まで流れ落ちる。従って、通風口より本体ケースの内部 に浸入する恐れはほとんどない。[Operation] Water droplets on the upper surface of the body case of the electric device flow down to the side surface along the groove extending from the upper surface of the case to the side surface at a downward slope. Therefore, there is almost no risk of infiltration into the main body case through the ventilation port.

【実施例】【Example】

図１及び図２は本考案を充電装置に適用した一実施例を示している。１は下ケ ース１ａ及び上ケース１ｂからなる本体ケース、２は上ケース１ｂの上面に設け られた被充電電池（図示せず）の充電用挿入口、３は充電用挿入口２内に露出す る一対の充電接点、４は下ケース１ａ内に配され、充電接点３を支持するプリン ト基板、５はプリント基板４上に設けられた電子部品であり、発熱体であるトラ ンス等を含む。６は発熱体である電子部品５と熱的に連結されて、プリント基板 ４の下方に配された放熱板である。 1 and 2 show an embodiment in which the present invention is applied to a charging device. Reference numeral 1 is a main body case made up of a lower case 1a and an upper case 1b, 2 is a charging insertion opening for a battery to be charged (not shown) provided on the upper surface of the upper case 1b, and 3 is a charging insertion opening 2. A pair of exposed charging contacts 4 are disposed in the lower case 1a, and a printed circuit board 5 supporting the charging contacts 3 is an electronic component provided on the printed circuit board 4 such as a transformer which is a heating element. including. A heat radiating plate 6 is disposed below the printed circuit board 4 so as to be thermally connected to the electronic component 5 which is a heating element.

【０００８】 ７は上ケース１ｂの上面から一側面まで延在して互いに平行に設けられた複数 の溝であり、これら溝７は、前記一側面に向かって下り傾斜で設けられている。 更に、溝７の底壁は、その中央部分が低く形成されており、この実施例では樋形 状になっている。なお、この形状は樋形状に限らず、中央部分が低くなるように 階段形状としてもよい。Reference numeral 7 denotes a plurality of grooves that extend from the upper surface of the upper case 1b to one side surface and are provided in parallel with each other. The grooves 7 are provided with a downward slope toward the one side surface. Further, the bottom wall of the groove 7 is formed so that the central portion thereof is low, and has a gutter shape in this embodiment. Note that this shape is not limited to the gutter shape, and may be a step shape so that the central portion becomes low.

【０００９】 ８は溝７の両側壁に開口形成された通風口であり、この通風口８は本体ケース １の内部の熱を外部へ放出し得る範囲で、可能な限りに狭く開口形成されている 。Reference numeral 8 denotes a ventilation port formed on both side walls of the groove 7. The ventilation port 8 is formed as narrow as possible within a range in which the heat inside the body case 1 can be released to the outside. There is.

【００１０】 斯る構成において、雨水等による水滴が本体ケース１の上面に降りかかって溝 ７内に浸入した場合、これら溝７が、本体ケース１の一側面に向かって下り傾斜 となっているので、水滴は溝７を伝わって本体ケース１の一側面に向かって流れ る。従って、水滴は、本体ケース１の上面に溜まって通風口８から本体ケース１ 内部に浸入することはほとんどない。In such a configuration, when water droplets such as rainwater fall on the upper surface of the main body case 1 and enter the grooves 7, the grooves 7 are inclined downward toward one side surface of the main body case 1. Therefore, the water droplets flow along the groove 7 toward one side surface of the main body case 1. Therefore, water droplets hardly accumulate on the upper surface of the main body case 1 and enter the main body case 1 through the ventilation holes 8.

【００１１】 図３は本考案の他の実施例を示しており、この実施例では、溝７の側壁に形成 された通風口８は、本体ケース１の側面に向かって狭くなるように開口されてい る。これにより、毛管現象によって、本体ケース１内への水滴の浸入をより確実 に防止している。なお、その他の構成については、前述の実施例と同じであるた め、説明を割愛する。FIG. 3 shows another embodiment of the present invention. In this embodiment, the ventilation port 8 formed on the side wall of the groove 7 is narrowed toward the side surface of the body case 1. ing. This more reliably prevents water droplets from entering the main body case 1 due to the capillary phenomenon. The rest of the configuration is the same as that of the above-mentioned embodiment, so its explanation is omitted.

【考案の効果】[Effect of device]

本考案は、発熱部品を内蔵する本体ケースの上面に通風口を形成した電気機器 において、前記通風口は、前記本体ケースの上面から側面まで延在して設けられ た溝の側壁に開口形成されると共に、前記溝の底壁は前記側面に向かって下り傾 斜となっているので、本体ケースの上面に降りかかった水滴は、溝を伝って流れ 、本体ケースの上面に溜まることはない。従って、通風口を経て本体ケースに雨 水等の水滴が浸入することを抑制し、内部の電気回路の損傷を防止することがで きる。 The present invention relates to an electric device in which a ventilation opening is formed on an upper surface of a main body case containing a heat-generating component, the ventilation opening being formed in a side wall of a groove extending from an upper surface to a side surface of the main body case. In addition, since the bottom wall of the groove is inclined downward toward the side surface, the water droplets that have fallen on the upper surface of the main body case flow along the groove and do not collect on the upper surface of the main body case. Therefore, it is possible to prevent water droplets such as rainwater from entering the main body case through the ventilation port and prevent damage to the internal electric circuit.
