Description
本発明は、二次電池を装着した電気掃除機に関する。 The present invention relates to a vacuum cleaner equipped with a secondary battery.
従来の充電式のハンディタイプの電気掃除機は、例えば特許文献１に示すように電気掃除機本体に二次電池を装着し、電気掃除機本体を充電用スタンドに置くことにより、電気掃除機本体の二次電池を充電する。電気掃除機本体は、充電後、充電用スタンドから取り外し、電気掃除機本体だけで掃除をすることができるようになる。しかしながら、従来のハンディタイプの電気掃除機では、掃除中に二次電池の充電量が減少することにより十分な電力を供給できなくなると、再び充電しなければ掃除を続けることができなくなるという問題がある。 A conventional rechargeable handy type vacuum cleaner, for example, as shown in Patent Document 1, a secondary battery is mounted on the main body of the vacuum cleaner, and the main body of the vacuum cleaner is placed on a charging stand. Recharge the secondary battery. After charging, the main body of the vacuum cleaner can be removed from the charging stand and cleaned only by the main body of the vacuum cleaner. However, in the conventional handy type vacuum cleaner, if the amount of charge of the secondary battery decreases during cleaning and sufficient power cannot be supplied, cleaning cannot be continued unless it is charged again. is there.
この問題を解決するために、例えば特許文献２に示すように充電用スタンドで予備の二次電池を充電できるようにし、電気掃除機本体の二次電池の充電量が減少したら予備に使われる二次電池と交換することにより掃除を続けられるようにすることが開示されている。 In order to solve this problem, for example, as shown in Patent Document 2, it is possible to charge a spare secondary battery with a charging stand, and when the charge amount of the secondary battery of the main body of the vacuum cleaner is reduced, the secondary battery is used as a spare. It is disclosed that cleaning can be continued by replacing the secondary battery.
しかしながら、従来の方法では、電気掃除機本体が充電用スタンドに置かれている場合、電気掃除機本体の二次電池と充電用スタンドに置かれた予備の二次電池との両方を並行して充電することになり、１つの二次電池に対する充電時間が２倍に延びてしまうという問題がある。 However, in the conventional method, when the vacuum cleaner body is placed on the charging stand, both the secondary battery of the vacuum cleaner body and the spare secondary battery placed on the charging stand are placed in parallel. Therefore, there is a problem that the charging time for one secondary battery is doubled.
本発明は、上述した従来技術の問題点を解決するためになされたものであり、その目的は、充電用スタンドに予備の二次電池を装着した状態で電気掃除機本体が充電用スタンドに配置されても、電気掃除機本体に装着された二次電池の充電効率を落とすことなく予備に使われる二次電池の充電が行える電気掃除機を提供することである。 The present invention has been made to solve the above-described problems of the prior art, and its purpose is to place the vacuum cleaner body on the charging stand in a state where a spare secondary battery is mounted on the charging stand. However, it is an object of the present invention to provide a vacuum cleaner that can charge a secondary battery used as a spare without reducing the charging efficiency of the secondary battery mounted on the main body of the vacuum cleaner.
本発明のある態様による電気掃除機は、電動機を含む電動吸引部と、第１の接点と、前記電動吸引部に装着され、前記電動機を駆動する第１の二次電池と、前記第１の接点と接続され、前記第１の二次電池の充電を制御する第１の充電制御部と、を有する掃除機本体と、前記掃除機本体が配置されると前記第１の接点と接触する第２の接点と、第２の二次電池を装着する装着部と、前記装着部に装着された前記第２の二次電池の充電を制御する第２の充電制御部と、を有する充電用スタンドと、を有することを特徴とする。 An electric vacuum cleaner according to an aspect of the present invention includes an electric suction unit including an electric motor, a first contact, a first secondary battery that is attached to the electric suction unit and drives the electric motor, and the first A vacuum cleaner body having a first charge control unit connected to a contact and controlling charging of the first secondary battery; and a first body that contacts the first contact when the vacuum cleaner body is disposed. A charging stand having two contact points, a mounting portion for mounting the second secondary battery, and a second charging control unit for controlling charging of the second secondary battery mounted on the mounting portion. It is characterized by having.
この構成によれば、充電用スタンドに予備に使われる第２の二次電池を装着した状態で掃除機本体が充電用スタンドに配置されても、第１の二次電池と第２の二次電池とを独立して充電することができるので、第１の二次電池が放電しても第２の二次電池に交換することにより電気掃除機を継続して使用することができる。 According to this configuration, even if the main body of the vacuum cleaner is disposed on the charging stand in a state where the second secondary battery used as a spare is mounted on the charging stand, the first secondary battery and the second secondary battery are arranged. Since the battery can be charged independently, even if the first secondary battery is discharged, the vacuum cleaner can be used continuously by replacing it with the second secondary battery.
上記電気掃除機において、前記第１の充電制御部が前記第１の二次電池を充電する電流量と、前記第２の充電制御部が前記第２の二次電池を充電する電流量と、は異なるようにしてもよい。 In the vacuum cleaner, the first charging control unit charges the first secondary battery, and the second charging control unit charges the second secondary battery. May be different.
こうすれば、充電用スタンドに予備に使われる第２の二次電池を装着した状態で掃除機本体が充電用スタンドに配置され、電源が２個の二次電池を平行して充電するのに必要な出力を有しない場合でも、第１の二次電池を充電する電流量を多くし、第２の二次電池を充電する電流量を少なくすれば、２個の二次電池の充電が可能になり、第１の二次電池が放電しても第２の二次電池に交換することにより電気掃除機を継続して使用することができる。 In this way, the main body of the vacuum cleaner is placed on the charging stand with the secondary secondary battery used as a spare attached to the charging stand, and the power source charges the two secondary batteries in parallel. Even if it does not have the required output, it is possible to charge two secondary batteries by increasing the amount of current charging the first secondary battery and decreasing the amount of current charging the second secondary battery. Thus, even when the first secondary battery is discharged, the vacuum cleaner can be used continuously by replacing it with the second secondary battery.
上記電気掃除機において、前記第１の充電制御部は、前記第１の二次電池を急速充電し、前記第２の充電制御部は、前記第２の二次電池をトリクル充電するようにしてもよい。 In the electric vacuum cleaner, the first charge control unit rapidly charges the first secondary battery, and the second charge control unit performs trickle charge on the second secondary battery. Also good.
こうすれば、充電用スタンドに予備に使われる第２の二次電池を装着した状態で掃除機本体が充電用スタンドに配置され、電源が２個の二次電池を平行して充電するのに必要な出力を有しない場合でも、第１の二次電池は急速充電し、第２の二次電池はトリクル充電で時間をかけて充電することができるので、第１の二次電池が放電しても第２の二次電池に交換することにより電気掃除機を継続して使用することができる。 In this way, the main body of the vacuum cleaner is placed on the charging stand with the secondary secondary battery used as a spare attached to the charging stand, and the power source charges the two secondary batteries in parallel. Even if it does not have the required output, the first secondary battery can be charged quickly and the second secondary battery can be charged over time by trickle charging, so the first secondary battery is discharged. Even if it replaces with a 2nd secondary battery, a vacuum cleaner can be continued and used.
本発明の他の態様による電気掃除機は、電動機を含む電動吸引部と、第１の接点と、前記電動吸引部に装着され、前記電動機を駆動する第１の二次電池と、前記第１の接点と接続され、前記第１の二次電池の充電を制御する第１の充電制御部と、を有する掃除機本体と、電源からの電源電流が供給される電源入力端子と、前記電源入力端子と第１の配線によって接続され、前記掃除機本体が配置されると前記第１の接点と接触する第２の接点と、第２の二次電池を装着する装着部と、前記電源入力端子と第２の配線によって接続され、前記装着部に装着された前記第２の二次電池の充電を制御する第２の充電制御部と、を有する充電用スタンドと、を有し、前記第２の充電制御部は、前記第１の配線に流れる電流量を検出し、前記電流量が所定の値未満である場合は、前記第２の二次電池を急速充電し、前記第１の電流量が所定の値以上である場合は、前記第２の二次電池をトリクル充電する、ことを特徴とする。 An electric vacuum cleaner according to another aspect of the present invention includes an electric suction unit including an electric motor, a first contact, a first secondary battery that is attached to the electric suction unit and drives the electric motor, and the first A vacuum cleaner body having a first charge control unit that is connected to the first contact point and controls charging of the first secondary battery, a power input terminal to which a power source current from a power source is supplied, and the power input A second contact that is connected to the terminal by a first wiring and contacts the first contact when the cleaner body is disposed; a mounting portion for mounting a second secondary battery; and the power input terminal And a second charging control unit that controls charging of the second secondary battery mounted on the mounting unit and connected by a second wiring, and the second charging control unit. The charge control unit detects the amount of current flowing through the first wiring, and the amount of current is determined. The second secondary battery is rapidly charged when the value is less than the value of, and the second secondary battery is trickle charged when the first current amount is equal to or greater than a predetermined value. Features.
この構成によれば、充電用スタンドに予備に使われる第２の二次電池を装着した状態で掃除機本体が充電用スタンドに配置されても、第１の二次電池が優先的に急速充電され、第２の充電制御部は第１の二次電池が満充電状態になったことを検知することにより、以降は第２の二次電池を急速充電することができるので、第１の二次電池と第２の二次電池とを切り替えて急速充電することができ、より短時間に第２の二次電池を準備できるので、第１の二次電池が放電しても第２の二次電池に交換することにより電気掃除機を継続して使用することができる。 According to this configuration, even when the vacuum cleaner body is placed on the charging stand with the second secondary battery used as a spare attached to the charging stand, the first secondary battery is preferentially quickly charged. Then, the second charge control unit detects that the first secondary battery is in a fully charged state, so that the second secondary battery can be rapidly charged thereafter. The secondary battery and the second secondary battery can be switched and rapidly charged, and the second secondary battery can be prepared in a shorter time. Therefore, even if the first secondary battery is discharged, the second secondary battery can be prepared. By replacing the secondary battery, the vacuum cleaner can be used continuously.
上記電気掃除機において、前記第２の充電制御部は、トリクル充電を開始後、所定の時間が経過したらトリクル充電を停止し、前記所定の時間が経過後さらに所定の期間が経過したら再度充電を開始するようにしてもよい。 In the above vacuum cleaner, the second charge control unit stops trickle charging when a predetermined time has elapsed after starting trickle charging, and charges again when a predetermined period elapses after the predetermined time elapses. You may make it start.
本発明によれば、充電用スタンドに予備に使われる第２の二次電池を装着した状態で掃除機本体が充電用スタンドに配置されても、第１の二次電池と第２の二次電池とを独立して充電することができるので、第１の二次電池が放電しても第２の二次電池に交換することにより電気掃除機を継続して使用することができる。 According to the present invention, even if the vacuum cleaner body is disposed on the charging stand with the second secondary battery used as a spare attached to the charging stand, the first secondary battery and the second secondary battery are disposed. Since the battery can be charged independently, even if the first secondary battery is discharged, the vacuum cleaner can be used continuously by replacing it with the second secondary battery.

次に、第１の実施形態に係る電気掃除機１の動作について、図３を参照して説明する。図３は、第１の実施形態に係る第１の充電制御部及び第２の充電制御部の動作を示すタイミング図である。図３では、時点ｔ０において、第２の二次電池１４２は、装着部１４４に装着されていないものとする。また、ＡＣアダプタ１５０は、第１の二次電池１４０を充電する電流量と第２の二次電池１４２を充電する電流量とを合計した電流量以上の出力ＡＤＰＯを有するものとする。 Next, operation | movement of the vacuum cleaner 1 which concerns on 1st Embodiment is demonstrated with reference to FIG.

Output from the out terminal. The second charging control unit 208 trickle-charges the second secondary battery 142 with the output OUT2 for a predetermined time (for example, 48 hours) from time t1 to time t3. The second charging control unit 208 stops trickle charging of the second secondary battery 142 at a time t3 when a predetermined time has elapsed.

Can be used.
（第２の実施形態）
第１の実施形態では、第１の充電制御部１０８は、第１の二次電池１４０を急速充電し、第２の充電制御部２０８は、第２の二次電池１４２をトリクル充電するように説明したが、第２の充電制御部２０８は第１の二次電池１４０が満充電状態になったか否かを監視し、第１の二次電池１４０が満充電状態になるまでは第２の二次電池１４２をトリクル充電し、第１の二次電池１４０が満充電状態になったら第２の二次電池１４２を急速充電するようにしてもよい。
(Second Embodiment)
In the first embodiment, the first charging control unit 108 rapidly charges the first secondary battery 140, and the second charging control unit 208 trickle-charges the second secondary battery 142. As described above, the second charging control unit 208 monitors whether or not the first secondary battery 140 is in a fully charged state, and the second charging control unit 208 does not operate until the first secondary battery 140 is in a fully charged state. The secondary battery 142 may be trickle charged, and when the first secondary battery 140 is fully charged, the second secondary battery 142 may be rapidly charged.

図４に示すように、充電用スタンド２００は、第１の配線１６１に電流検出回路１６３が並列に接続されている。第２の充電制御部２０８は、電流検出回路１６３が検出する第１の配線１６１に流れる電流量Ｉを監視する。第１の充電制御部１０８は、第１の二次電池１４０が満充電状態になると出力ＯＵＴ１をトリクル充電に必要な電流に切り替えるので、第１の配線１６１に流れる電流量Ｉは、第１の二次電池１４０が満充電状態になった時点で減少する。第２の充電制御部２０８は、電流量Ｉが所定の値Ｉｔｈ以上の場合はトリクル充電に必要な電流量の出力ＯＵＴ２を出力し、電流量Ｉが所定の値Ｉｔｈ未満の場合は急速充電に必要な電流量の出力ＯＵＴ２に切り替える。 As shown in FIG. 4, in the charging stand 200, a current detection circuit 163 is connected in parallel to the first wiring 161. The second charge control unit 208 monitors the amount of current I flowing through the first wiring 161 detected by the current detection circuit 163. Since the first charge control unit 108 switches the output OUT1 to a current necessary for trickle charge when the first secondary battery 140 becomes fully charged, the amount of current I flowing through the first wiring 161 is set to It decreases when the secondary battery 140 is fully charged. The second charge control unit 208 outputs an output OUT2 of a current amount necessary for trickle charging when the current amount I is equal to or greater than a predetermined value Ith, and performs rapid charging when the current amount I is less than the predetermined value Ith. Switch to the output OUT2 of the required current amount.
次に、第２の実施形態に係る電気掃除機の動作について、図５を参照して説明する。図５は、第２の実施形態に係る第１の充電制御部及び第２の充電制御部の動作を示すタイミング図である。図５では、時点ｔ０において、第２の二次電池１４２は、装着部１４４に装着されていないものとする。 Next, operation | movement of the vacuum cleaner which concerns on 2nd Embodiment is demonstrated with reference to FIG. FIG. 5 is a timing diagram illustrating operations of the first charge control unit and the second charge control unit according to the second embodiment.

図５に示すように、時点ｔ０でＡＣアダプタ１５０が接続されると、ＡＣアダプタ１５０からの出力ＡＤＰＯが第１の配線１６１を介して第１の充電制御部１０８のｉｎ端子に出力され、第２の配線１６２を介して第２の充電制御部２０８のｉｎ端子に出力される。 As shown in FIG. 5, when the AC adapter 150 is connected at time t0, the output ADPO from the AC adapter 150 is output to the in terminal of the first charge control unit 108 via the first wiring 161, and It is output to the in terminal of the second charging control unit 208 via the second wiring 162.
第１の充電制御部１０８は、時点ｔ０から、第１の二次電池１４０を急速充電するための定電圧定電流の出力ＯＵＴ１をｏｕｔ端子から出力する。第１の二次電池１４０は、第１の充電制御部１０８のｏｕｔ端子からの出力ＯＵＴ１により急速充電され、時点ｔ２で満充電状態となる。第１の充電制御部１０８は、第１の二次電池１４０が満充電状態となったことを検知し、時点ｔ２以降は、ｏｕｔ端子からトリクル充電に必要な電流量の出力ＯＵＴ１を出力する。 The first charging control unit 108 outputs, from the out terminal, an output OUT1 of constant voltage and constant current for rapidly charging the first secondary battery 140 from time t0. The first secondary battery 140 is rapidly charged by the output OUT1 from the out terminal of the first charge control unit 108, and becomes fully charged at time t2. The first charging control unit 108 detects that the first secondary battery 140 is fully charged, and outputs an output OUT1 having a current amount necessary for trickle charging from the out terminal after time t2.
第２の充電制御部２０８は、第１の配線１６１に流れる電流量Ｉが所定の値Ｉｔｈ以上か否かを監視している。第２の二次電池１４２は、時点ｔ１で装着部１４４に装着される。第２の充電制御部２０８は、時点ｔ１で電流量Ｉが所定の値Ｉｔｈ以上なので、第２の二次電池１４２をトリクル充電に必要な電流量の出力ＯＵＴ２をｏｕｔ端子から出力する。 The second charging control unit 208 monitors whether or not the amount of current I flowing through the first wiring 161 is equal to or greater than a predetermined value Ith. The second secondary battery 142 is attached to the attachment portion 144 at time t1. Since the current amount I is equal to or greater than the predetermined value Ith at the time t1, the second charge control unit 208 outputs an output OUT2 of the current amount necessary for trickle charging of the second secondary battery 142 from the out terminal.
第２の充電制御部２０８は、時点ｔ２で第１の二次電池１４０が満充電状態となったことを、電流量Ｉが所定の値Ｉｔｈ未満となったことで検知する。第２の充電制御部２０８は、時点ｔ２以降、第２の二次電池１４２を急速充電するための定電圧定電流の出力ＯＵＴ２をｏｕｔ端子から出力する。第２の充電制御部２０８は、時点ｔ３で第２の二次電池１４２が満充電状態となったことを検知し、時点ｔ３以降は、ｏｕｔ端子からトリクル充電に必要な電流量の出力ＯＵＴ２を出力する。第２の充電制御部２０８は、第２の二次電池１４２を時点ｔ３から出力ＯＵＴ２によりトリクル充電する。 The second charge control unit 208 detects that the first secondary battery 140 is fully charged at time t2 by the current amount I being less than a predetermined value Ith. The second charging control unit 208 outputs, from the out terminal, an output OUT2 of a constant voltage and a constant current for rapidly charging the second secondary battery 142 after the time point t2. The second charging control unit 208 detects that the second secondary battery 142 is fully charged at time t3, and outputs the output OUT2 of the amount of current necessary for trickle charging from the out terminal after time t3. Output. Second charging control unit 208 trickle charges second secondary battery 142 with output OUT2 from time t3.
