この考案は充電式電気かみそシなどの充電式小型電気機
器の改良に関するものである。[Detailed Description of the Invention] This invention relates to the improvement of rechargeable small electric appliances such as rechargeable electric stoves.
たとえば充電式電気かみそbでは、モータに電源スィッ
チを介して直列接続される被充電電池を充電する場合、
上記電源スィッチOFFに設定してから所定の時間上記
被充電電池を充電させるようになっているが、この被充
電電池が満充電になった′″1筐でさらに充電状態に放
置されると、無駄に電力が消費されることになるから、
上記被充電電池の充電が完了すると同時に、圧電素子な
どのブザーを発音させて充電完了を報知できるようにし
たものがすでに開発されつつある。For example, in rechargeable electric oven B, when charging the battery connected in series to the motor via the power switch,
After the power switch is set to OFF, the battery to be charged is charged for a predetermined period of time, but if the battery to be charged is left in a fully charged state in the first case, Because electricity will be wasted,
A device is already being developed that can notify the completion of charging by emitting a buzzer such as a piezoelectric element at the same time as the charging of the battery to be charged is completed.
而して、音声出力としては微弱な圧電素子からの発音を
使用者に報知音として聞き取り易くさせるため、ケース
本体の外壁の上記ブザーと対応する部分には、音数出口
を形成するのが通例である。Therefore, in order to make it easier for the user to hear the sound output from the piezoelectric element, which is weak as an audio output, as a notification sound, it is customary to form a tone exit in the part of the outer wall of the case body that corresponds to the buzzer. It is.
ところが、この種被充電電池の充電時間は安全充電では
、数時間以上の長時間を要するため、たとえば、使用者
が昼間に充電を開始したものの、深夜に充電が完了して
上記報知音が発音された場合にあっては、上記音数出口
からの報知音が昼間では予測されない程に強調されて安
眠を妨げる逆効果を呈することにもiりかねなく、この
ため使用者はこのような時間帯に充電が完了しないよう
に配慮しながら被充電電池の充電を行なわなければなら
ず、使い勝手が悪い。However, the charging time for this type of rechargeable battery requires a long time, several hours or more, for safe charging, so for example, if a user starts charging during the day, charging is completed in the middle of the night and the above notification sound is emitted. In such a case, the notification sound from the above-mentioned sound outlet may be unexpectedly emphasized during the daytime, which may have the opposite effect of hindering a good night's sleep. The battery to be charged must be charged while taking care not to completely charge the battery, which is inconvenient to use.
lた周知のように電気かみそシの使用時には、意外に多
くの毛屑が飛散するものであう、上記のように音数出口
を単に設けただけでは上記毛屑が音数出口からケース本
体内に侵入する欠点もある。As is well known, when using an electric shaver, a surprisingly large amount of hair is scattered.If the sound outlet is simply provided as described above, the hair waste will flow from the sound outlet into the case body. There is also the disadvantage of intruding into
したがって、この考案は電源スィッチの操作釦に接続さ
れて、この釦のOFF領域で、音数出口の開口面積を可
変させることにより、充電完了時の報知音の音量を調整
でき、しかも剪断時の毛屑が上記音数出口から侵入する
のを防止できる充電式小型電気機器を提供することを目
的とする。Therefore, this device is connected to the operation button of the power switch, and by changing the opening area of the number outlet in the OFF region of this button, the volume of the notification sound when charging is completed can be adjusted, and moreover, it is possible to adjust the volume of the notification sound at the time of shearing. It is an object of the present invention to provide a small rechargeable electric device that can prevent hair debris from entering through the above-mentioned sound outlet.
