【発明の詳細な説明】 産業上の利用分野 本発明は、電気二重層キャパシタと蓄電池とで駆動す
る電気掃除機に関するものである。Description: TECHNICAL FIELD The present invention relates to a vacuum cleaner driven by an electric double layer capacitor and a storage battery.
従来の技術 電気掃除機は従来100VのAC電源を用いるものが主流で
ある。これに対し乾電池式や充電式などのコードレス掃
除機も用いられるようになってきている。AC電源を用い
るものは吸引力など掃除性能の点では非常に優れている
が、掃除をする時長いコードがじゃまになりコードレス
化の要求が増してきた。このような要求に対して開発さ
れた充電式の掃除機は、電源としてNi−Cdや鉛などの二
次電池を用いるもので操作は非常に便利である。しかし
ながら、(1)一回の使用時の充電に長時間要するこ
と、(2)瞬時に大きな吸引力が得られないこと、
(3)冬季の低温時には大きな吸引力が得られないこ
と、(4)重量が重いこと、(5)定期的に電池の交換
が必要であることなどの問題点を有している。2. Description of the Related Art Conventionally, the mainstream of vacuum cleaners uses a 100V AC power supply. On the other hand, cordless vacuum cleaners such as dry cell type and rechargeable type have been used. Those using an AC power supply are very good in terms of cleaning performance, such as suction power, but when cleaning, long cords are in the way and the demand for cordless is increasing. The rechargeable vacuum cleaner developed for such a demand uses a secondary battery such as Ni-Cd or lead as a power source, and is very convenient to operate. However, (1) that it takes a long time to charge in one use, (2) that a large suction force cannot be obtained instantaneously,
(3) There is a problem that a large suction force cannot be obtained at a low temperature in winter, (4) the weight is heavy, and (5) the battery needs to be periodically replaced.
発明が解決しようとする課題 従来のように鉛蓄電池やNi−Cd電池のような二次電池
を駆動源とする電気掃除機はコードレスにできる反面上
記の(1)〜(5)のような課題を有している。これら
の課題は以下に記述するように二次電池の原理と構成と
に起因することである。Problems to be Solved by the Invention A conventional vacuum cleaner using a secondary battery such as a lead storage battery or a Ni-Cd battery as a drive source can be made cordless, but has the above-mentioned problems (1) to (5). have. These problems are attributable to the principle and configuration of the secondary battery as described below.
(1)パワー密度が小さい。(1) The power density is small.
電池は放電が電極と電解液との電気化学反応過程を含
むために瞬時に流すことのできる電流値が制限される。
このため積載が必要な電池の容量は、モータ始動時やモ
ータに逆の負荷がかかるような大電流放電時の電流値に
より決まり、この値は定常使用時の電流値により非常に
大きなものになってしまう。すなわち、重量当りに流す
ことの可能な最大電流値が小さいために電池の総重量を
大きくせざるを得ない。In a battery, the amount of current that can flow instantaneously is limited because discharge involves an electrochemical reaction process between an electrode and an electrolytic solution.
For this reason, the capacity of the battery that needs to be loaded is determined by the current value at the time of starting the motor or at the time of discharging a large current such that a reverse load is applied to the motor, and this value becomes very large due to the current value during steady use. Would. That is, since the maximum current value that can flow per weight is small, the total weight of the battery must be increased.
(2)充放電サイクル寿命が短い。(2) The charge / discharge cycle life is short.
電池は充電放電サイクルが電極と電解液との電気化学
反応過程(酸化還元反応)を含むために、初期の電池特
性を維持できるサイクル寿命には限度がある。通常の鉛
蓄電池では500サイクルである。Since the charge and discharge cycle of a battery includes an electrochemical reaction process (oxidation-reduction reaction) between an electrode and an electrolyte, the cycle life that can maintain the initial battery characteristics is limited. A typical lead-acid battery has 500 cycles.
(3)使用温度範囲が狭い。(3) The operating temperature range is narrow.
上記のように電気化学反応プロセスは雰囲気温度によ
り反応の進行速度が大きく影響される。特に0゜以下の
低温では酸化還元反応の速度、電解液中でのイオンの移
動度などが極端に小さくなるために電池の起電力が小さ
くなったり、内部抵抗値が大きくなって大電流充放電が
困難になる。As described above, the progress rate of the electrochemical reaction process is greatly affected by the ambient temperature. In particular, at a low temperature of 0 ° or less, the speed of the oxidation-reduction reaction and the mobility of ions in the electrolytic solution become extremely small, so that the electromotive force of the battery becomes small, and the internal resistance becomes large, resulting in a large current charge / discharge. Becomes difficult.
(4)構成材料に鉛と硫酸を使用している。(4) Lead and sulfuric acid are used as constituent materials.
鉛蓄電池は、電極と鉛と酸化鉛を、電解液に硫酸水溶
液を用いているために使用後廃棄時に公害廃棄物処理の
必要がある。Since lead acid batteries use electrodes, lead and lead oxide, and an aqueous solution of sulfuric acid as an electrolytic solution, it is necessary to dispose of pollutant waste at the time of disposal after use.
(5)充電に長時間を要する。(5) It takes a long time to charge.
充電電流の大きさが制限されるために充電に長い時間
を要する。A long time is required for charging because the magnitude of the charging current is limited.
電源として二次電池を用いる限りこれらの点は改善す
るべき課題として残る。(1)から(5)の課題を解決
するためには電気掃除機の電源系を抜本的に考え直さな
ければならない。As long as a secondary battery is used as a power source, these points remain as issues to be improved. In order to solve the problems (1) to (5), the power supply system of the vacuum cleaner needs to be drastically reconsidered.

になるために掃除操作が非常に便利である。Effect According to the present invention, a large current can be passed with almost no limitation at the time of charge / discharge, the charge / discharge characteristics at a low temperature are excellent, the power density is large, the maintenance-free and the charge / discharge cycle life is semi-permanent. Since the multilayer capacitor is used as a power supply, a vacuum cleaner having a light weight, a small size, a non-polluting and excellent suction performance such as suction power can be obtained, and a cleaning operation is very convenient because it is cordless.

て実現する画期的な掃除機である。Since the electric double layer capacitor of the present invention can be instantaneously charged with a large current, the capacitor is fully charged simply by placing the cleaning unit on the charging power supply unit for a short time during the cleaning operation and charging. So very short time If the capacitor is charged by the above, the required electric capacity that can be stored in the capacitor of the cleaning unit is sufficient to be able to maintain the rotation of the motor for the time for actually performing the suction operation continuously. The secondary battery cannot be used in this way because it cannot be rapidly charged even though the electric capacity that can be stored is more than 100 times that of the electric double layer capacitor. This is an epoch-making vacuum cleaner realized only with a low-resistance electric double layer capacitor.
