Description

【0001】
【発明の属する技術分野】
本発明は、バッテリーの充電時に発生する水素ガスを酸化し水蒸気として排気するバッテリー用の水素ガス処理装置に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
例えば、アウトドア用電源として、廉価な車載用のバッテリーが用いられているが、バッテリーは充電時に水素ガスを発生するため車室内では充電させない仕様となっている。
【0003】
また、最近、車載ソーラセルの電力を充電するバッテリーを車室内に置きたい要望もあるが、やはり充電時に水素ガスを発生するため、車室内には置けない仕様とせざるを得ない。
【0004】
一方、バッテリー技術の中に触媒栓という技術がある。
【0005】
この触媒栓は、バッテリーの上部の排気口となるネジ込み孔に栓体をネジ込み装着するもので、バッテリーの内部で発生する酸素ガスと水素ガスをこの栓体内に設けた触媒により水蒸気化して自然冷却し、水として再び排気口を介してバッテリー内へ戻し、無補水化を実現しようとするものである。
【0006】
しかし、このような触媒栓は排気口となるネジ込み口にネジ込み装着する構成であるから、このネジ込み口の規格が各社同一ではないために、バッテリー交換の際、他社のバッテリーを購入すると装着できない場合がある。
【0007】
本発明は、このような問題に着目し、水素ガスを水として再びバッテリー内へ戻すというこれまでの触媒栓の基本的な発想を転換し、水素ガスを水蒸気としこの水蒸気をそのまま外部へ排気する構成とすると共に、更にバッテリーに装着するカバー体に触媒を設ける構成として、バッテリーのメーカーが異なっても装着でき、バッテリー内で発生する水素ガスを水蒸気化して外部へ排出させることができ、バッテリーを車室内にも置くことができることとなる画期的なバッテリー用の水素ガス処理装置を提供することを目的としている。
【0008】
【課題を解決するための手段】
添付図面を参照して本発明の要旨を説明する。
【0009】
バッテリー1に装着するカバー体2の上部位置に排気部3を設け、バッテリー1から発生する水素ガスを酸化させ水蒸気とする触媒4を前記排気部3に配設したことを特徴とするバッテリー用の水素ガス処理装置に係るものである。
【0010】
また、前記カバー体2を、前記バッテリー1の上部を覆うように上方からバッテリー1に装着し得るように構成したことを特徴とする請求項1記載のバッテリー用の水素ガス処理装置に係るものである。
【0011】
また、前記カバー体2の上部位置に設けた排気部3に、前記触媒4を収納した通気可能な収納部5を設けて、前記触媒4を前記排気部3に配設したことを特徴とする請求項1,2のいずれか1項に記載のバッテリー用の水素ガス処理装置に係るものである。
【0012】
また、前記排気部3に容体取付部5Bを設け、前記触媒4を通気可能に収納した収納体5Aを前記容体取付部5Bに配設して前記収納部5を構成したことを特徴とする請求項3記載のバッテリー用の水素ガス処理装置に係るものである。
【0013】
また、前記排気部3に設ける前記触媒4を収納した収納部5を、前記カバー体2の内部上面の最上部位置に配設して、前記バッテリー1から発生する水素ガスがカバー体2の内部上面に停留してしまうことなく前記触媒4に導かれ、この触媒4によって酸化された水蒸気が前記カバー体2の外部へと排気されるように構成したことを特徴とする請求項1〜4のいずれか1項に記載のバッテリー用の水素ガス処理装置に係るものである。
【0014】
【発明の実施の形態】
最良と考える本発明の実施の形態(発明をどのように実施するか)を、図面に基づいてその作用効果を示して簡単に説明する。
【0015】
例えばバッテリー1に本発明たるカバー体2を装着する。あるいは、バッテリー1に予めカバー体2を装着したカバー付バッテリーを提供する。
【0016】
このバッテリー1においては、充電時に水素ガスが発生しても、この水素ガスはバッテリー1の外部へそのまま排気されずカバー体2内へ排気され、カバー体2の上部に設けた触媒4へと導かれ、この触媒4によって酸化され水蒸気となってカバー体2上部の排気部3から外部へと排出される。
【0017】
従って、水素ガスは水蒸気となって外部へ排出されるからバッテリー1を車両室内に置くことも取り付け配設することも可能となる。
【0018】
また、この触媒4はカバー体2の排気部3を設けた上部位置に配設されているから、水素ガスは空気より軽いためこの触媒4へと導かれて酸化され水蒸気となってから外部へ排気される。
【0019】
しかも、この触媒4はバッテリー1に装着するカバー体2に設け、従来の触媒栓のようにネジ込み口にネジ込み装着する構成でないため、バッテリー1の外形規格にさほどの相違がないことから、バッテリー1のメーカーが異なっても容易に装着可能となる。
【0020】
【実施例】
本発明の具体的な実施例について図面に基づいて説明する。
【0021】
バッテリー1に装着するカバー体2の上部位置に排気部3を設け、バッテリー1から発生する水素ガスと酸素ガスを再結合させて水蒸気とする触媒4を前記排気部3に配設した構成とし、本実施例のカバー体2は、バッテリー1の上面部を覆ってこのバッテリー1の上面部の液口栓6の通気孔7から排気される水素ガスと酸素ガスとを導くための導入空間8が形成される底部開口形の箱状体に構成し、上方からバッテリー1に装着し得るように構成している。
【0022】
本実施例では、このカバー体2の上部位置に通気可能な排気部3を設け、この排気部3に前記触媒4を収納した通気可能な収納部5を設けて、前記触媒4を前記排気部3に配設している。
【0023】
また、前記排気部3は、カバー体2の上壁部を突出状態に設けた突出部9の上下の閉塞壁部3Aに通気孔3Bを設けた構成とし、この閉塞壁部3A間に収納部分を形成して前記収納部5とし、この収納部5内に粒状の前記触媒4を収納した構成としている。
【0024】
従って、この収納部5がカバー体2の内部上面の最上部位置に配設され、前記バッテリー1から発生する水素ガス、酸素ガスがカバー体2の内部上面に停留してしまうことなく自然に前記触媒4に導かれ、この触媒4によって酸化された(水素ガスと酸素ガスとが結合した)水蒸気が前記排気部3からカバー体2の外部へと排出されるように構成している。
【0025】
従って、例えばバッテリー1にカバー体2を装着する。あるいは、バッテリー1に予めカバー体2を装着したカバー付バッテリーを提供すれば、バッテリー1の充電時に発生する水素ガスは、そのままバッテリー1の外部へ排出されずカバー体2内へ排出され、カバー体2の上部に設けた触媒4へと導かれ、この触媒4によって酸化され水蒸気となってカバー体2上部の排気部3から外部へと排出される。
【0026】
即ち、バッテリー1内で水素ガス・酸素ガスが発生すると、バッテリー1の上面部の例えば液口栓6に設けてある通気孔7からカバー体2内の導入空間8に排気され、水素ガス・酸素ガスは空気より軽く排気部3も上部に設けてあるため、カバー体2内を上昇し、排気部3へと導かれる。
【0027】
この排気部3を設ける部分に触媒4を配設しているため、水素ガスと酸素ガスはこの触媒4へと導かれて水蒸気となってから外部へ排気される。
【0028】
具体的には、本実施例ではカバー体2内を上昇する水素ガス・酸素ガスは、収納部5の下部閉塞壁部3Aの通気孔3Bを通って収納部5内へ導かれ触媒4と接触した後、水蒸気となって上部閉塞閉差壁部3Aの通気孔3Bを通って外部へ排出される。
【0029】
従って、水素ガスは水蒸気となって外部へ排出されるからバッテリー1を車両室内へ置くことも配設することも可能となる。
【0030】
しかも、この触媒4はバッテリー1に装着するカバー体2に設け、従来の触媒栓のようにネジ込み口にネジ込み装着する構成でないため、バッテリー1の外形規格にさほどの相違がないことから、バッテリー1のメーカーが異なっても容易に装着可能となる。
【0031】
また、本実施例では、触媒4を収納した収納部5をカバー体2の内部上面2Aの最上部位置、即ち導入空間8の最上部に設けたため、水素ガスが上部に停留することなく、確実に触媒4へ導かれて水蒸気となり外部へ排出される。
【0032】
本実施例では、単に前述のように突出部9を設け、この突出部9を収納部5として構成することで前記作用・効果を確実に発揮できると共に、構成が簡単となり、量産性に秀れ、触媒4の収納も容易となる。
【0033】
尚、前記触媒4への導入作用が一層良好となるようにカバー体2の内部上面2Aを収納部5へ向かって上昇傾斜する傾斜面を付けても良い。
【0034】
図1〜図4は前述のように構成した第1実施例であるが、この第1実施例ではパッキン10をカバー体2の下端縁部に設け、バッテリー1の上面を密閉状態に覆うようにバッテリー1の上面部に載置する構成としている。
【0035】
このカバー体2とバッテリー1とに係合構造を設けて係合装着するように構成しても良いし、ベルト掛けなどして取付固定しても良いが、水素ガスは空気より軽く上昇するため、完全密閉したり、完全に係合固定する必要もなく、またカバー体2内の内圧が過剰に高くなることを防止することを考慮して完全密閉状態に係合装着しないように構成している。
【0036】
尚、図中符号13はバッテリー1上面の極栓11と係合するための配線12をカバー体2内へ導くための配線12挿通部で、グロメットなどを利用して外部と通気遮断状態に配線できるようにした構成で、14は極栓11と係合する係合具である。
【0037】
また、図5に示す第2実施例は、前記排気部3に容体取付部5Bを設け、前記触媒4を通気可能に収納した収納体5Aを前記容体取付部5Bに配設して前記収納部5を構成した実施例である。
【0038】
具体的には、予め通気性を有する多孔質材で形成した収納体5A内に触媒4を収納し、この触媒4入りの収納体5Aを容体取付部5Bに係合し、押さえ板(係止部)15で止着して収納部5を構成したものである。
【0039】
このように構成することで、排気部3の形成と共に、触媒4のこの排気部3への配設構成が一層容易となり、一層量産性に秀れる。
【0040】
また、図6はカバー体2を袋状に構成した第3実施例を示すもので、この実施例においては、排気部3(収納部5)を設けた上板部2Bにバッテリー1の上面部に載置する接地脚部2Cを垂設して、上板部2Bの下方に導入空間8が確保されるように構成し、更にこの上板部2Bにバッテリー1の少なくとも上部部分を覆う袋部2Dを垂設し、この袋部2Dによってバッテリー1の上部を覆い、バッテリー1内で発生する水素ガスを前述の実施例と同様に外部へ逃さずに補足するように構成している。
【0041】
また、たとえ水素ガスは軽くても袋部2Dの下方から逃げ出ないようにするために、袋部2Dの下部をしぼり込み、カバー体2の装着状態を安定化するように構成している。
【0042】
即ち、袋部2Dの開口袋部にしぼりひも16を挿通し、このしぼりひも16を引き出すことで、袋部2Dの開口部が狭められ、バッテリー1の胴部にしぼり込み当接するように構成している。
【0043】
【発明の効果】
本発明は上述のように構成したから、水素ガスはそのまま外部へは排気されず確実に水蒸気となって外部へ排出されるため、バッテリーを車室内などへ置くことも可能となり、しかもバッテリーに装着するカバー体に触媒を設ける構成であるため、触媒栓とは違い例えばバッテリーのメーカーが異なっても装着可能となり、触媒栓に比べて著しく汎用性が向上する極めて画期的なバッテリー用の水素ガス処理装置となる。
【0044】
また、請求項2記載の発明においては、一層確実にして良好に前記作用・効果を発揮するバッテリー用の水素ガス処理装置となる。
【0045】
また、請求項3記載の発明においては、更に前記触媒の配設が容易となり、簡易な構成にして量産性に秀れ、一層確実にして良好に前記作用・効果を発揮するバッテリー用の水素ガス処理装置となる。
【0046】
また、請求項4記載の発明においては、排気部3の形成と共に触媒4の排気部3への配設構成が一層容易となり、一層量産性に秀れたバッテリー用の水素ガス処理装置となる。
【0047】
また、請求項5記載の発明においては、バッテリーから発生する水素ガスが内部上面に停留しずらく、一層良好に触媒へ導かれるため、一層量産性に秀れた極めて実用性に秀れたバッテリー用の水素ガス処理装置となる。

BACKGROUND OF THE INVENTION
The present invention relates to a hydrogen gas processing apparatus for a battery that oxidizes hydrogen gas generated during charging of the battery and exhausts it as water vapor.
[0002]
[Prior art and problems to be solved by the invention]
For example, an inexpensive in-vehicle battery is used as an outdoor power source, but the battery generates hydrogen gas during charging and is not charged in the passenger compartment.
[0003]
Recently, there is a desire to place a battery for charging the power of the in-vehicle solar cell in the vehicle interior. However, since hydrogen gas is also generated during charging, the specification cannot be placed in the vehicle interior.
[0004]
On the other hand, there is a technology called a catalyst plug in the battery technology.
[0005]
This catalyst plug is a screw that is screwed into a screw hole that becomes an exhaust port at the top of the battery, and oxygen gas and hydrogen gas generated inside the battery are vaporized by a catalyst provided in the plug body. It is naturally cooled and returned to the battery as water again through the exhaust port to achieve no water replenishment.
[0006]
However, because such a catalyst plug is configured to be screwed into a screw-in port serving as an exhaust port, the standards of this screw-in port are not the same for each company. It may not be possible to install.
[0007]
The present invention pays attention to such a problem, changes the basic idea of the catalyst plug so far to return hydrogen gas as water again into the battery, and uses hydrogen gas as water vapor to exhaust the water vapor to the outside as it is. In addition to the configuration, a catalyst is provided on the cover body to be attached to the battery, so that it can be attached even if the manufacturer of the battery is different, and the hydrogen gas generated in the battery can be vaporized and discharged to the outside. An object of the present invention is to provide an epoch-making hydrogen gas treatment apparatus for a battery that can be placed in a passenger compartment.
[0008]
[Means for Solving the Problems]
The gist of the present invention will be described with reference to the accompanying drawings.
[0009]
An exhaust part 3 is provided at an upper position of a cover body 2 attached to the battery 1, and a catalyst 4 that oxidizes hydrogen gas generated from the battery 1 to form water vapor is disposed in the exhaust part 3. The present invention relates to a hydrogen gas processing apparatus.

[0011]
Further, the exhaust part 3 provided at the upper position of the cover body 2 is provided with a ventable storage part 5 storing the catalyst 4, and the catalyst 4 is disposed in the exhaust part 3. The hydrogen gas processing apparatus for a battery according to any one of claims 1 and 2.
[0012]
In addition, a container mounting part 5B is provided in the exhaust part 3, and a storage body 5A storing the catalyst 4 so as to be able to vent is disposed in the container mounting part 5B to constitute the storage part 5. The present invention relates to the hydrogen gas treatment device for a battery according to Item 3.
[0013]
In addition, a storage portion 5 for storing the catalyst 4 provided in the exhaust portion 3 is disposed at the uppermost position on the inner upper surface of the cover body 2, so that hydrogen gas generated from the battery 1 flows inside the cover body 2. 5. The structure according to claim 1, wherein water vapor that is guided to the catalyst 4 without being retained on the upper surface and is oxidized by the catalyst 4 is exhausted to the outside of the cover body 2. The present invention relates to the hydrogen gas processing apparatus for a battery according to any one of the items.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
The best mode for carrying out the present invention (how to carry out the invention) will be briefly described with reference to the drawings.
[0015]
For example, the cover body 2 according to the present invention is attached to the battery 1. Alternatively, a battery with a cover in which a cover body 2 is previously attached to the battery 1 is provided.
[0016]
In this battery 1, even if hydrogen gas is generated during charging, this hydrogen gas is not exhausted as it is to the outside of the battery 1 but is exhausted into the cover body 2 and led to the catalyst 4 provided above the cover body 2. Then, it is oxidized by the catalyst 4 and becomes steam, and is discharged to the outside from the exhaust part 3 above the cover body 2.
[0017]
Accordingly, since hydrogen gas is discharged to the outside as water vapor, it is possible to place the battery 1 in the vehicle compartment or to install it.
[0018]
In addition, since the catalyst 4 is disposed at the upper position of the cover body 2 where the exhaust part 3 is provided, the hydrogen gas is lighter than air, so it is led to the catalyst 4 and oxidized to become water vapor and then to the outside. Exhausted.
[0019]
Moreover, since the catalyst 4 is provided on the cover body 2 to be attached to the battery 1 and is not configured to be screwed into the screw-in opening like a conventional catalyst plug, there is not much difference in the external specification of the battery 1. Even if the manufacturer of the battery 1 is different, it can be easily mounted.
[0020]
【Example】
Specific embodiments of the present invention will be described with reference to the drawings.
[0021]
An exhaust unit 3 is provided at an upper position of the cover body 2 attached to the battery 1, and a catalyst 4 is formed in the exhaust unit 3 by recombining hydrogen gas and oxygen gas generated from the battery 1 to form water vapor. The cover body 2 of the present embodiment has an introduction space 8 for covering the upper surface portion of the battery 1 and guiding hydrogen gas and oxygen gas exhausted from the vent hole 7 of the liquid plug 6 on the upper surface portion of the battery 1. The bottom-opening box-shaped body is formed so that the battery 1 can be mounted from above.
[0022]
In the present embodiment, a ventable exhaust portion 3 is provided at an upper position of the cover body 2, and a ventable storage portion 5 storing the catalyst 4 is provided in the exhaust portion 3, so that the catalyst 4 is disposed in the exhaust portion. 3 is arranged.

In addition, the exhaust part 3 has a structure in which a vent hole 3B is provided in the upper and lower closed wall parts 3A of the protruding part 9 provided with the upper wall part of the cover body 2 in a protruding state. The storage unit 5 is formed, and the granular catalyst 4 is stored in the storage unit 5.
[0024]
Accordingly, the storage portion 5 is disposed at the uppermost position on the inner upper surface of the cover body 2, and the hydrogen gas and oxygen gas generated from the battery 1 are naturally retained without stopping on the inner upper surface of the cover body 2. The water vapor guided to the catalyst 4 and oxidized by the catalyst 4 (hydrogen gas and oxygen gas combined) is discharged from the exhaust part 3 to the outside of the cover body 2.
[0025]
Therefore, for example, the cover body 2 is attached to the battery 1. Alternatively, if a battery with a cover in which the cover body 2 is attached in advance to the battery 1 is provided, the hydrogen gas generated when the battery 1 is charged is not directly discharged to the outside of the battery 1 but is discharged into the cover body 2, 2 is led to the catalyst 4 provided at the upper part of the gas 2, and is oxidized by the catalyst 4 to become water vapor and discharged from the exhaust part 3 at the upper part of the cover body 2 to the outside.
[0026]
That is, when hydrogen gas / oxygen gas is generated in the battery 1, the hydrogen gas / oxygen gas is exhausted from the vent hole 7 provided in, for example, the liquid plug 6 on the upper surface of the battery 1 to the introduction space 8 in the cover body 2. Since the gas is lighter than air and the exhaust part 3 is also provided at the upper part, the gas rises in the cover body 2 and is guided to the exhaust part 3.
[0027]
Since the catalyst 4 is disposed in the portion where the exhaust part 3 is provided, the hydrogen gas and the oxygen gas are led to the catalyst 4 to become water vapor and then exhausted to the outside.

After that, the water vapor is discharged to the outside through the vent hole 3B of the upper closed wall portion 3A.
[0029]
Accordingly, since the hydrogen gas is discharged to the outside as water vapor, the battery 1 can be placed or disposed in the vehicle compartment.
[0030]
Moreover, since the catalyst 4 is provided on the cover body 2 to be attached to the battery 1 and is not configured to be screwed into the screw-in opening like a conventional catalyst plug, there is not much difference in the external specification of the battery 1. Even if the manufacturer of the battery 1 is different, it can be easily mounted.
[0031]
Further, in the present embodiment, since the storage portion 5 storing the catalyst 4 is provided at the uppermost position of the inner upper surface 2A of the cover body 2, that is, the uppermost portion of the introduction space 8, the hydrogen gas does not stay at the upper portion and is reliably Then, it is led to the catalyst 4 and becomes steam and discharged to the outside.
[0032]
In the present embodiment, the protrusion 9 is simply provided as described above, and the protrusion 9 is configured as the storage portion 5 so that the operation and effect can be surely achieved, the configuration is simplified, and mass productivity is excellent. The storage of the catalyst 4 is also facilitated.
[0033]

[0035]
The cover body 2 and the battery 1 may be configured to be engaged and mounted by engagement, or may be attached and fixed by a belt or the like, but hydrogen gas rises lighter than air. It is not necessary to be completely sealed or completely engaged and fixed, and in order to prevent the internal pressure in the cover body 2 from becoming excessively high, it is configured not to be engaged and mounted in a completely sealed state. Yes.
[0036]
In the figure, reference numeral 13 denotes a wiring 12 insertion portion for guiding the wiring 12 for engaging with the electrode plug 11 on the upper surface of the battery 1 into the cover body 2. The wiring is cut off from the outside using a grommet or the like. Reference numeral 14 denotes an engaging tool that engages with the pole plug 11.
[0037]
Further, in the second embodiment shown in FIG. 5, a container mounting portion 5B is provided in the exhaust section 3, and a storage body 5A in which the catalyst 4 is stored so as to be ventilated is disposed in the container mounting section 5B. FIG.
[0038]
Specifically, the catalyst 4 is stored in a storage body 5A formed in advance of a porous material having air permeability, the storage body 5A containing the catalyst 4 is engaged with the container mounting portion 5B, and a pressing plate (locking) Part) 15 and is configured to constitute the storage part 5.
[0039]
With this configuration, the formation of the exhaust part 3 and the arrangement of the catalyst 4 in the exhaust part 3 become easier and the mass productivity is further improved.
[0040]
FIG. 6 shows a third embodiment in which the cover body 2 is formed in a bag shape. In this embodiment, the upper surface portion of the battery 1 is provided on the upper plate portion 2B provided with the exhaust portion 3 (housing portion 5). A grounding leg portion 2C placed on the top plate portion 2B is constructed so that an introduction space 8 is secured below the upper plate portion 2B, and a bag portion that covers at least the upper portion of the battery 1 on the upper plate portion 2B. 2D is suspended, and the upper portion of the battery 1 is covered by the bag portion 2D, and the hydrogen gas generated in the battery 1 is supplemented without escape to the outside as in the above-described embodiment.
[0041]
Further, even if the hydrogen gas is light, the lower portion of the bag portion 2D is squeezed so that the hydrogen gas does not escape from the lower side of the bag portion 2D, so that the mounting state of the cover body 2 is stabilized.
[0042]
That is, by inserting the string 16 through the opening bag part of the bag part 2D and pulling out the string 16, the opening part of the bag part 2D is narrowed, and the bag part 2D is squeezed into contact with the body part of the battery 1. ing.
