Description

本発明は、電池残量の表示部を用いて、電池劣化度合いを表示させる制御をする機能を備えた電気掃除機に関するものである。 The present invention relates to an electric vacuum cleaner having a function of controlling to display the degree of battery deterioration by using a display unit of a remaining battery level.

二次電池で動作する電気機器は、電池残量を表示し、動作が停止するまでの残り時間の目安を表現しているものが多い。しかしながら、電池は消耗品であるため、劣化度合いによっては、電池の消耗時間が早くなるため、電池残量の表示と実際の動作時間が必ずしも一致しているとは言い難く、使用者にとっては、電池残量表示から、あとどのくらい使用できるか分かり難いという課題がある。これを解決するために、先行技術文献である特許文献１においては、劣化度合いに応じた表示をする制御方法が考えられている。 Many electrical devices that operate on a secondary battery display the remaining battery level and represent a guideline for the remaining time until the operation stops. However, since the battery is a consumable item, the battery consumption time becomes faster depending on the degree of deterioration, so it is difficult to say that the display of the remaining battery level and the actual operating time always match, and for the user, There is a problem that it is difficult to know how much more it can be used from the battery level display. In order to solve this problem, in Patent Document 1, which is a prior art document, a control method for displaying according to the degree of deterioration is considered.

先行技術文献である特許文献１においては、電池の劣化状態を判別し、それを表示部に表示する機能を特徴としている。しかしながら、表示部に劣化度合いを直接メッセージにより表現しているため、十分な表示スペースの確保が必要となり、例えばスティック型掃除機等のように表示部が限られたスペースである場合には、劣化度合いを表現することが困難である。 Patent Document 1, which is a prior art document, is characterized by a function of determining a deteriorated state of a battery and displaying it on a display unit. However, since the degree of deterioration is directly expressed by a message on the display unit, it is necessary to secure a sufficient display space. For example, when the display unit has a limited space such as a stick type vacuum cleaner, the deterioration It is difficult to express the degree.

上記課題を解決するために、電気掃除機本体と、該電気掃除機本体に取付ける二次電池を備え、該電気掃除機本体に運転制御用マイコンと電池電圧検出部と表示部を備え、該二次電池部に劣化度合いを算出する電池制御用マイコンを備え、運転制御用マイコンは、該電池電圧検出部と二次電池の劣化度合いから、表示部の点灯や点滅を制御する機能を備えることで達成する。 In order to solve the above problems, the main body of the electric vacuum cleaner and a secondary battery to be attached to the main body of the electric vacuum cleaner are provided, and the main body of the electric vacuum cleaner is provided with a microcomputer for operation control, a battery voltage detection unit and a display unit.

以下、本発明を下記の実施例により説明する。 Hereinafter, the present invention will be described with reference to the following examples.

図１（a）（ｂ）は、着脱可能な二次電池２を電力源とする充電式掃除機１の上面図および側面図である。充電式掃除機１は、ループ上ハンドルの上部に手元操作部３を配置し、運転モード切替スイッチ３ａ〜３ｃとＬＥＤ表示部４を備えている。 1A and 1B are a top view and a side view of a rechargeable vacuum cleaner 1 using a removable secondary battery 2 as a power source. The rechargeable vacuum cleaner 1 has a hand operation unit 3 arranged on the upper part of the handle on the loop, and includes operation mode changeover switches 3a to 3c and an LED display unit 4.

図２（a）（ｂ）（ｃ）は手元操作部３とLED表示部４の詳細説明図である。図２（a）は、手元操作部３とLED表示部４の拡大図である。図２（ｂ）（ｃ）は、LED表示部４の詳細説明図である。手元操作部１は３つの運転モード切替スイッチ３ａ〜３ｃと、表示部４を備える。LED表示部４は、電池マークを表現したセグメントモジュール４ａで構成されたものであり、直下のＬＥＤ素子により、点灯、点滅を制御することができる。 2A, 2B, and 2C are detailed explanatory views of the hand operation unit 3 and the LED display unit 4. FIG. 2A is an enlarged view of the hand operation unit 3 and the LED display unit 4. 2 (b) and 2 (c) are detailed explanatory views of the LED display unit 4. The hand operation unit 1 includes three operation mode changeover switches 3a to 3c and a display unit 4. The LED display unit 4 is composed of a segment module 4a expressing a battery mark, and lighting and blinking can be controlled by an LED element directly below the LED display unit 4.

運転モード切替スイッチ３の操作により、運転モードに対応した電動送風機を駆動させ、運転することができる。運転中はLED表示部４の内側セグメント（B,C,D）は、電池電圧によって残量表示を内側セグメントの点灯数により表現し、外側セグメント（A）は、劣化度合いを点滅で表現させることで、運転時間および電池交換時期の目安を表現させる。 By operating the operation mode changeover switch 3, the electric blower corresponding to the operation mode can be driven and operated. During operation, the inner segment (B, C, D) of the LED display unit 4 expresses the remaining amount display by the number of lights of the inner segment by the battery voltage, and the outer segment (A) expresses the degree of deterioration by blinking. Then, let's express the guideline of the operation time and the battery replacement time.

二次電池２の電圧値は電池残量と相関があるので、電池残量の判定に使うことができる。二次電池の劣化度合いは、電池パック内の電池制御ＩＣにより判定し、劣化度の判定に使用する。 Since the voltage value of the secondary battery 2 correlates with the remaining battery level, it can be used to determine the remaining battery level. The degree of deterioration of the secondary battery is determined by the battery control IC in the battery pack and used to determine the degree of deterioration.

図３は本発明のブロック図であり、二次電池２と電池制御ＩＣ（電池制御用マイコン）５と運転制御用マイコン６と電圧検知部７と表示部４から構成される。運転制御用マイコン６は電圧検出部７による二次電池の電圧値Ｖから、電池残量を計算し、表示部４の内側セグメントの点灯を制御する。また、電池劣化度は、電池制御ＩＣ５が判定したものを運転制御用マイコンに伝送し、劣化度合いに対応した外側セグメントの点滅周期を制御する。 FIG. 3 is a block diagram of the present invention, which is composed of a secondary battery 2, a battery control IC (battery control microcomputer) 5, an operation control microcomputer 6, a voltage detection unit 7, and a display unit 4. The operation control microcomputer 6 calculates the remaining battery level from the voltage value V of the secondary battery by the voltage detection unit 7, and controls the lighting of the inner segment of the display unit 4. Further, the battery deterioration degree is transmitted to the operation control microcomputer what is determined by the battery control IC5, and the blinking cycle of the outer segment corresponding to the deterioration degree is controlled.

以下、実際の表示方法を具体例として説明する。二次電池２がリチウムイオン電池（使用電圧２．６Ｖ〜４．２Ｖ）６セルで構成されている場合に、電池残量に関しては、表示部４の内側セグメントの点灯を、満充電時はセグメントＢ、Ｃ、ＤのＬＥＤ３個を点灯し、残量７０％になった時点でＤのＬＥＤを消灯し、B,CのLED２個を点灯したままにし、残量４０％になった時点でDを消灯したままでＣを消灯し、BのLED１個を点灯したままにし、残量１０％になった時点で、C,Dを消灯したままで、ＢのＬＥＤを点滅させる（点灯と消灯を繰り返す）ような制御を行う。残量１０％になった時点でBのLEDを点滅させることで、電池が減っていく表現を行う。 Hereinafter, the actual display method will be described as a specific example. When the secondary battery 2 is composed of 6 cells of a lithium ion battery (working voltage 2.6V to 4.2V), the inner segment of the display unit 4 is lit with respect to the remaining battery level, and the segment is lit when fully charged. Turn on the three LEDs B, C, and D, turn off the LED D when the remaining amount reaches 70%, leave the two LEDs B and C on, and when the remaining amount reaches 40%, D Turn off C with the light off, leave one LED on B on, and when the remaining amount reaches 10%, keep C and D off and blink the LED on B (turn on and off). Repeat). By blinking the LED of B when the remaining amount reaches 10%, the battery is depleted.

また、電池劣化度については、７０％になった時点で、セグメントAを１．５秒ＯＮ−０．５秒ＯＦＦの点滅周期により点滅させることで、電池劣化となっていることを表現する。電池交換が必要な条件になった場合は、７０％になった場合よりも早い点滅となるように、セグメントAを０．５秒ＯＮ−０．５秒ＯＦＦの点滅とし、使用者に電池交換時期の目安となっていることを表示する。 Further, regarding the degree of battery deterioration, when the degree of deterioration reaches 70%, the segment A is blinked in a blinking cycle of 1.5 seconds ON-0.5 seconds OFF to express that the battery has deteriorated. When the condition requires battery replacement, segment A is set to blink 0.5 seconds ON-0.5 seconds OFF so that it blinks faster than when it reaches 70%, and the user is asked to replace the battery. Display that it is a guideline for the time.

以上により、使用者が電池が劣化している状態で掃除を開始した場合に、電池残量の減り方が大きく運転時間が短いと感じた場合は、電池劣化度を示す点灯表示から、取扱説明書に記載の、電池劣化時の目安時間を参考に使用時間を把握することができる。 From the above, if the user starts cleaning with the battery deteriorated and feels that the remaining battery power is greatly reduced and the operating time is short, the instruction manual will be displayed from the lighting display indicating the degree of battery deterioration. The usage time can be grasped by referring to the estimated time when the battery deteriorates described in the manual.

本実施例では、約３０％低下毎に点灯・点滅周期の制御を行っているが、さらに細分化した内容で表示制御を実施しても良い。 In this embodiment, the lighting / blinking cycle is controlled every time the decrease is about 30%, but the display control may be performed with further subdivided contents.
