Description
【０００１】[0001]
本考案は、歯ブラシ本体が蓄電池を電源として動作する電動歯ブラシ装置に関 するものである。 The present invention relates to an electric toothbrush device in which a toothbrush body operates using a storage battery as a power source.
【０００２】[0002]
従来の電動歯ブラシ装置としては、歯ブラシ本体が蓄電池を電源として動作し 、歯ブラシ本体を充電装置に装着すると、蓄電池の充電が行われるものがある。 As a conventional electric toothbrush device, there is a device in which the toothbrush main body operates by using a storage battery as a power source and the storage battery is charged when the toothbrush main body is attached to the charging device.
【０００３】[0003]
ところで、このような常時充電方式の電動歯ブラシ装置の場合に、蓄電池を完 全に放電するまで使用せずに繰り返し充電すると、蓄電池を満充電することがで きなくなるといういわゆる蓄電池のメモリ効果を生じる。これは、例えば蓄電池 を完全に放電するまで使用せずに充電するという使用を繰り返すと、蓄電池内部 に活性化されない部分が生じ、この不活性化部分は上記使用が繰り返される限り 充電しても活性化されずに、それだけ充電電圧が低下するものと考えられる。 By the way, in the case of such an electric toothbrush device of the constant charging type, if the storage battery is repeatedly charged without being used until it is completely discharged, a so-called storage battery memory effect occurs in which the storage battery cannot be fully charged. .. This is because, for example, if the storage battery is repeatedly used without being used until it is completely discharged, a part of the storage battery that is not activated will be generated, and this inactivated portion will be active even if it is charged as long as the above use is repeated. It is considered that the charging voltage is reduced by that much without being converted.
【０００４】 本考案は上述の点に鑑みて為されたものであり、その目的とするところは、 蓄電池のメモリ効果を最小限に止めることができる電動歯ブラシ装置を提供する ことにある。The present invention has been made in view of the above points, and an object thereof is to provide an electric toothbrush device capable of minimizing the memory effect of a storage battery.
【０００５】[0005]
本考案では、上記目的を達成するために、ほぼ一定回数の充電あるいはほぼ一 定期間の使用後に歯ブラシ本体を充電装置に装着して充電を行う際に、充電装置 が自動的に蓄電池を完全放電させた後に再充電するようにしてある。 According to the present invention, in order to achieve the above object, the charging device automatically discharges the storage battery when the toothbrush body is attached to the charging device for charging after a certain number of times of charging or after a period of almost constant use. After that, the battery is recharged.
【０００６】[0006]
本考案は、上述のようにほぼ一定回数の充電あるいはほぼ一定期間の使用後に 、一旦蓄電池を完全放電させることにより、使用者が蓄電池の容量を使い切るこ となく充電を行うという使い方をしても、ほぼ定期的に自動的に蓄電池を完全放 電状態まで放電させることができ、これにより内部の不活性化が進行することを 防止して、蓄電池のメモリ効果を最小限に止めることができる。 As described above, the present invention can be used even if the user fully charges the storage battery after charging it for a fixed number of times or after using it for a fixed period of time, so that the user can charge the storage battery without exhausting its capacity. The battery can be automatically and almost completely discharged to the fully discharged state, which prevents internal deactivation and minimizes the memory effect of the battery.

図１に本考案の一実施例を示す。この図１は充電装置の回路構成を示すもので あり、交流電源を変圧器２を用いて降圧し、整流回路３で整流して制御回路１用 の電源を作成し、この電源を用いて制御回路１が歯ブラシ本体内に収められた蓄 電池の充電を行う。ここで、蓄電池の充電は制御回路１内部に設けられた充電電 流制限回路４を通して行い、蓄電池を所定電流以下の充電電流で充電するように して、蓄電池に過電流が流れることを防止してある。 FIG. 1 shows an embodiment of the present invention. This Fig. 1 shows the circuit configuration of the charging device. An AC power supply is stepped down using a transformer 2 and rectified by a rectifier circuit 3 to create a power supply for a control circuit 1, and control is performed using this power supply. The circuit 1 charges the storage battery housed in the toothbrush body. Here, the storage battery is charged through the charging current limiting circuit 4 provided inside the control circuit 1 so that the storage battery is charged with a charging current not more than a predetermined current to prevent an overcurrent from flowing into the storage battery. There is.
【０００８】 以上の構成は通常の電動歯ブラシ装置も備える構成であるが、本実施例では蓄 電池のメモリ効果を防止するために次の構成を備える。つまり、充電装置の充電 端子Ｔ1 ，Ｔ2 間に接続され、この充電端子Ｔ1 ，Ｔ2 間を短絡することにより 蓄電池を放電する放電回路５と、この放電回路５による蓄電池の強制放電の開始 時点を設定するタイマ回路６とを備える。ここで、タイマ回路６の計時時間は、 通常の歯ブラシ本体の使用状態（大人の朝晩の使用）で１ケ月位が適当である。The above-described configuration is also a configuration including a normal electric toothbrush device, but in the present embodiment, the following configuration is provided in order to prevent the memory effect of the storage battery. That is, the discharge circuit 5 connected between the charging terminals T 1 and T 2 of the charging device and discharging the storage battery by short-circuiting the charging terminals T 1 and T 2 and the forced discharge of the storage battery by the discharging circuit 5 And a timer circuit 6 for setting a start time point. Here, it is appropriate that the timer circuit 6 keeps a time of about one month in the normal usage state of the toothbrush body (adult morning and evening use).
【０００９】 以下、この充電回路の動作について説明する。いま、上記タイマ回路６がタイ ムアップしていない場合には、歯ブラシ本体を充電装置に装着すると、そのとき から蓄電池の充電が行われる。 そして、上記タイマ回路６がタイムアップした時点で、歯ブラシ本体が充電装 置に装着されると、このときには歯ブラシ本体の充電は開始されず、制御回路１ が放電回路５を動作させることにより、まず蓄電池の放電が行われる。この放電 状態は蓄電池が完全放電されるまで継続される。ここで、この蓄電池が完全放電 されたことは、例えば充電端子Ｔ1 ，Ｔ2 間の電圧あるいは電流から制御回路１ が検知する。このようにして、一旦蓄電池が完全放電されると、この時点から制 御回路１が蓄電池の充電を開始する。そして、一旦蓄電池が完全放電されると、 タイマ回路６は新たにほぼ一定期間の計時動作を再開するようにしてある。The operation of this charging circuit will be described below. If the timer circuit 6 is not timed up, when the toothbrush body is attached to the charging device, the storage battery is charged from that time. Then, when the toothbrush body is attached to the charging device when the timer circuit 6 has timed out, charging of the toothbrush body is not started at this time, and the control circuit 1 operates the discharging circuit 5 to first The storage battery is discharged. This discharge state continues until the storage battery is completely discharged. Here, the complete discharge of the storage battery is detected by the control circuit 1 from the voltage or current between the charging terminals T 1 and T 2 , for example. In this way, once the storage battery is completely discharged, the control circuit 1 starts charging the storage battery from this point. Then, once the storage battery is completely discharged, the timer circuit 6 newly restarts the timing operation for a substantially constant period.
【００１０】 このようにすれば、ほぼ一定期間の使用後に、一旦蓄電池を完全放電させるこ とにより、使用者が蓄電池の容量を使い切ることなく充電を行うという使い方を しても、内部の不活性化が進行することを防止でき、蓄電池のメモリ効果を最小 限に止めることができる。従って、使用者が蓄電池のメモリ効果により生じた現 象を、蓄電池の寿命と間違えるということが無くなる。With this configuration, after the battery is used for a certain period of time, once the battery is completely discharged, even if the user charges the battery without exhausting the capacity of the battery, the internal inertness can be reduced. It is possible to prevent the progress of charging and to minimize the memory effect of the storage battery. Therefore, the user does not mistake the phenomenon caused by the memory effect of the storage battery for the life of the storage battery.
【００１１】 なお、上述の場合には使用時間に応じてほぼ定期的に蓄電池を完全放電させて いたが、使用回数が所定回数に達した時点で蓄電池を完全放電させるようにして もよい。この場合の使用回数は歯ブラシ本体が充電装置から外された回数をカウ ントするなどにより判定できる。 また、上述の場合には１人の使用の場合について説明したが、複数人で使用す る可能性もあるので、上記タイマ時間あるいはカウント回数などは使用人数に応 じて可変設定できるようにすることが好ましい。In the above case, the storage battery is completely discharged almost regularly according to the use time, but the storage battery may be completely discharged when the number of times of use reaches a predetermined number. In this case, the number of times of use can be determined by counting the number of times the main body of the toothbrush is removed from the charging device. In the above case, the case of one person's use was explained, but since it may be used by more than one person, the timer time or the number of counts can be variably set according to the number of persons used. Preferably.
【００１２】 さらに、上記ほぼ一定期間あるいはほぼ一定回数で蓄電池を放電する放電回路 ５及びタイマ回路６は必ずしも充電装置側に設ける必要はなく、歯ブラシ本体側 に設けてもよい。このように歯ブラシ本体側に上記回路を設けると、さらに使用 状況を的確に把握して、蓄電池を適当な時間に完全放電させることが可能である 。また、蓄電池の放電方法として自動的に歯ブラシ本体を駆動して放電させると いう方法を採用することもできる。Further, the discharge circuit 5 and the timer circuit 6 for discharging the storage battery in the above-mentioned substantially constant period or substantially constant number of times do not necessarily have to be provided on the charging device side, but may be provided on the toothbrush main body side. If the circuit is provided on the toothbrush main body side in this way, it is possible to accurately grasp the usage situation and completely discharge the storage battery at an appropriate time. Further, as a method of discharging the storage battery, a method of automatically driving the toothbrush body to discharge the battery can be adopted.
【００１３】[0013]
本考案は上述のように、ほぼ一定回数の充電あるいはほぼ一定期間の使用後に 歯ブラシ本体を充電装置に装着して充電を行う際に、充電装置が自動的に蓄電池 を完全放電させた後に再充電するようにしてあるので、使用者が蓄電池の容量を 使い切ることなく充電を行うという使い方をしても、ほぼ定期的に自動的に蓄電 池を完全放電状態まで放電させることができ、このため内部の不活性化が進行す ることを防止して、蓄電池のメモリ効果を最小限に止めることができる。 As described above, when the toothbrush body is attached to the charging device for charging after a certain number of times of charging or after a certain period of time, the charging device automatically completely recharges the storage battery and then recharges it. Therefore, even if the user charges the storage battery without using it up, the battery can be automatically and almost completely discharged to the fully discharged state. It is possible to prevent the inactivation of the battery from proceeding and to minimize the memory effect of the storage battery.
