従来の間欠作動式加熱器の一般的な間欠式加熱サイク
ルの原理は第３図に示す温度（横軸）、平衡圧力（縦
軸）の関係（加熱サイクルＡ→Ｂ→Ｃ→Ｄ→Ａ）で示さ
れる。以下金属水素化物−水素系を例にとって具体的に
説明する。The principle of the general intermittent heating cycle of the conventional intermittent operation type heater is the relationship between temperature (horizontal axis) and equilibrium pressure (vertical axis) shown in FIG. 3 (heating cycle A → B → C → D → A). Indicated by. The metal hydride-hydrogen system will be specifically described below as an example.
温度平衡圧力特性の異なる二種類の金属水素化物を用
い、まず同一温度で平衡圧力の低い金属水素化物（MH
1）で十分に水素を吸着したものを再生加熱温度THまで
加熱し（Ａの状態）、外気温度TA度で十分に水素を脱着
した、かつ同一温度で平衡圧力の高い金属水素化物（MH
2）と連通して水素の移動を行う（Ｂの状態）。この
際、MH2は発熱反応により熱を発生する。Two types of metal hydrides with different temperature equilibrium pressure characteristics are used.
A metal hydride (1) that has sufficiently adsorbed hydrogen is heated to the regenerative heating temperature T H (state A), has sufficiently desorbed hydrogen at the outside air temperature T A , and has a high equilibrium pressure at the same temperature ( MH
2) Communicate with and transfer hydrogen (state B). At this time, MH2 generates heat by an exothermic reaction.
次にMH1を冷却し（この熱は利用する）、MH2と連通す
ると、MH2の水素はMH1に移動し、MH1は発熱するのでこ
の熱も利用する。Next, when MH1 is cooled (uses this heat) and communicates with MH2, hydrogen in MH2 moves to MH1 and MH1 generates heat, so this heat is also used.
この場合最初にMH1を加熱したときの熱量のほぼ二倍
の熱量がMH2とMH1で得られる。但しこの場合はMH2とMH1
の両者の熱を交互に取り出すための熱回路を別に設ける
必要がある。In this case, almost twice the amount of heat when MH1 is first heated is obtained in MH2 and MH1. However, in this case MH2 and MH1
It is necessary to separately provide a heat circuit for alternately taking out the heat of both.
（発明が解決しようとする課題） 上述した一般的な間欠式加熱サイクルの場合は一回の
反応で利用出来る熱量が出来るだけ大きいことが肝要で
ある。そのためにMH1とその収容容器はできるだけ熱容
量の少ないものであることが望まれる。(Problems to be Solved by the Invention) In the case of the general intermittent heating cycle described above, it is important that the amount of heat that can be used in one reaction is as large as possible. Therefore, it is desirable that the MH1 and its container have as little heat capacity as possible.
しかし先にも述べた如くMH1の水素をMH2に返すために
はMH1を加熱（再生）温度THとする必要がある。（以下
再生過程と呼ぶ）このような加熱手段を設けることによ
ってMH1の周辺の熱容量は大幅に増加する。However, as described above, in order to return the hydrogen of MH1 to MH2, it is necessary to set MH1 to the heating (regeneration) temperature T H. By providing such heating means (hereinafter referred to as a regeneration process), the heat capacity around the MH1 is significantly increased.
又MH1とその容器は出来るだけ被加熱体に密着してい
ることが望ましいが、そのことは即ち再生過程における
熱が直接被加熱体に伝わってくることを意味する。この
加熱（再生）温度THは利用温度TUよりかなり高いため装
置が大掛かりとなり目的の場所に組込めない等いろいろ
不都合が生ずる場合が多い。Further, it is desirable that the MH1 and its container are in close contact with the object to be heated as much as possible, which means that the heat in the regeneration process is directly transferred to the object to be heated. Since this heating (regeneration) temperature T H is considerably higher than the use temperature T U, there are many inconveniences in that the device becomes large and it cannot be installed in the intended place.
本発明の目的はこのような不都合を解決し、出来るだ
け有効に発生する熱を利用し再生時に温度が上がりすぎ
ると言った困難を生じない間欠作動式加熱器を提供する
ものである。An object of the present invention is to solve such inconveniences and to provide an intermittent operation type heater which utilizes the heat generated as effectively as possible and does not cause the difficulty that the temperature rises too much during regeneration.
（課題を解決するための手段） 本発明は上記目的を達成するため、被加熱空間に置か

一及び第二の吸着物質を収容する容器と連結したことを
特徴とする。(Means for Solving the Problems) In order to achieve the above object, the present invention stores a first adsorbent substance contained in a container placed in a heated space, and a first adsorbent substance contained in a container placed in a lower temperature space. In addition to the intermittently actuated heater for moving and adsorbing the adsorbed substance adsorbed by the adsorbed second adsorbed substance through the valve and the pipe, the first adsorbed substance or an adsorbent having a temperature-pressure characteristic close to it. A third container containing a substance in a smaller amount than the first adsorbing substance and having a heating means is provided in the space in which the container containing the second adsorbing substance is placed, and the third container is provided with a pipe through a valve. It is characterized in that it is connected to a container containing the first and second adsorbent substances.
（作用） 本発明は、従来例において述べた如く被加熱体に密着
して設けられたMH1に外部空間に置かれたMH2より水素を
移動し、MH1を発熱させた後の再生行程を本発明の着眼
点であるから、この部分の作用を特に説明する。(Operation) As described in the conventional example, the present invention shows the regeneration process after the hydrogen is moved from the MH2 placed in the external space to the MH1 provided in close contact with the object to be heated to heat the MH1. Since this is the point of interest, the operation of this part will be described in particular.
MH1に吸蔵された水素をMH2に返すには、MH1を再生加
熱温度THに加熱する必要があることは先にも述べた。本
発明では再生行程においてMH1の水素を直接MH2に返すの
ではなく、まず外部空間に置かれた第三の容器と第一の
容器を弁を開いて連通することにより第一の容器内のMH
1に吸蔵された水素の一部を第三の容器内の金属水素化
物に吸蔵せしめることから始める。As described above, in order to return the hydrogen stored in MH1 to MH2, it is necessary to heat MH1 to the regeneration heating temperature T H. In the present invention, hydrogen in MH1 is not directly returned to MH2 in the regeneration process, but first the MH in the first container is opened by opening a valve to connect the third container and the first container placed in the external space.
The process starts by causing a part of the hydrogen stored in 1 to be stored in the metal hydride in the third container.
第一の容器及び第三の容器内の金属水素化物は同一な
いしはほぼ類似の温度平衡圧力特性を有するものであ
り、第三の容器の置かれた空間は第一の容器の置かれた
空間よりも温度が低いため水素は徐々に第一の容器から
第三の容器に移動する。この反応は比較的緩慢であるか
ら、反応による第一の容器の吸熱速度も遅いので、被加
熱体の温度が急速に低下することはない。The metal hydrides in the first container and the third container have the same or almost similar temperature equilibrium pressure characteristics, and the space where the third container is placed is smaller than the space where the first container is placed. Since the temperature is low, hydrogen gradually moves from the first container to the third container. Since this reaction is relatively slow, the endothermic rate of the first container due to the reaction is also slow, so that the temperature of the object to be heated does not drop rapidly.
第三の容器内の金属水素化物が飽和して水素の吸蔵反
応が停止したところで第一の容器との間の弁を閉じ、次
に第二の容器との間の弁を開き第三の容器を加熱し再生
加熱温度THにすると、第三の容器の水素は第二の容器に
移動する。移動が終われば弁を閉じ、第三の容器を外気
温度まで冷却し、再び第一の容器との間の弁を開くと残
っていた水素の一部が第三の容器に移動する。When the metal hydride in the third container is saturated and the hydrogen storage reaction stops, the valve between the first container and the second container is closed, and then the valve between the second container and the third container is opened. Is heated to a regeneration heating temperature T H , hydrogen in the third container moves to the second container. When the transfer is completed, the valve is closed, the third container is cooled to the outside air temperature, and when the valve between the first container and the first container is opened again, a part of the remaining hydrogen moves to the third container.
以下同様の操作を繰り返し第一の容器内のMH1がほぼ
水素を放出し終われば、再生行程は終了する。The same operation is repeated thereafter, and when MH1 in the first container has almost released hydrogen, the regeneration process ends.
（実施例） 例えば寒冷地において放置された自動車のハンドルは
非常に冷たくなっているので、エンジンを起動しても直

かりと握って車を運転することは苦痛である。こういう
ときにハンドルを即熱する方法が強く求められている。
本実施例はこのような自動車のステアリングハンドルの
急速加熱に応用した例であるが、勿論用途は他にいろい
ろ考えられ、用途に応じて使用される金属水素化物の量
や合金組成を変わる。更には吸着材、被吸着媒体の種類
も変わる。(Example) For example, the steering wheel of a car left in a cold region is very cold, so it will not warm up immediately after the engine is started. Therefore, hold the steering wheel of the car firmly before starting and drive the car. That is a pain. There is a strong demand for a way to heat the steering wheel immediately.
The present embodiment is an example applied to such rapid heating of the steering wheel of an automobile, but of course, there are various other possible uses, and the amount of metal hydride used and the alloy composition are changed depending on the use. Further, the types of adsorbent and adsorbed medium also change.
今ハンドルホイールの熱容量が約400cal/℃であると
して、これを０℃から35℃まで温度上昇させる。又金属
水素化物収容容器の重量は金属水素化物の重量と等しい
とする。Now, assuming that the heat capacity of the handle wheel is about 400 cal / ℃, raise the temperature from 0 ℃ to 35 ℃. The weight of the metal hydride storage container is equal to the weight of the metal hydride.
使用する金属水素化物は以下の如くにした。 The metal hydride used was as follows.
MH1:Ti0.55 Zr0.45 Mn0.8 Cr1.0 Cu0.2 MH2:Ti0.81 Zr0.19 Mn0.8 Cr1.0 Cu0.2 又これら金属水素化物の反応熱量及び分子量は夫々以
下の如くである。MH1: Ti 0.55 Zr 0.45 Mn 0.8 Cr 1.0 Cu 0.2 MH2: Ti 0.81 Zr 0.19 Mn 0.8 Cr 1.0 Cu 0.2 The reaction heat and molecular weight of these metal hydrides are as follows.
MH1:−6.8kcal/mol,176.0 MH2:−5.6kcal/mol,164.8 有効水素移動量ΔHx＝1.5 この前提にしたがって必要金属水素化物量を計算する
とMH1は657g,MH2は615g必要であることがわかる。MH1の
量はステアリングホイールの中に十分入りうる程度の量
である。MH1: −6.8 kcal / mol, 176.0 MH2: −5.6 kcal / mol, 164.8 Effective hydrogen transfer amount ΔHx = 1.5 Calculating the required metal hydride amount according to this assumption, it is found that MH1 needs 657 g and MH2 needs 615 g. . The amount of MH1 is large enough to fit inside the steering wheel.

ある。The basic cycle diagram of MH1 and MH2 by this combination is shown in Fig. 3. At this time, the heating (regeneration) temperature T H is 100 degrees, the utilization temperature T U is 35 degrees, the outside air temperature T A is 7 degrees, and the endothermic temperature T is C is -10 degrees.

してMH1,MH2と連通する水素配管を設けてある。FIG. 1 is a configuration diagram of an embodiment of the present invention applied to an automobile. As shown in the drawing, MH1 is installed in a steering wheel 1 of the automobile, MH2 is installed in an outer container 2 of the automobile,
It is connected by piping through the valve 6. Also, 100 g of metal hydride Ti 0.57 Zr 0.43 Mn 0.8 Cr 1.0 Cu 0.2 (MH3), which is close to MH1 but has a temperature-pressure characteristic lower than a certain temperature, is stored in a double-tube type container with an inner tube serving as a hot water passage. This is installed in the outdoor container 3 of the automobile, and hydrogen pipes are provided which communicate with MH1 and MH2 via valves 4 and 5, respectively.

止すると自然放冷で外気温度まで低下する。Further, the inner pipe is connected to an engine cooling water pipe 8 through a valve 7 and, if necessary, engine cooling water is used,
Although it is possible to heat MH3 to 80 degrees or more, the outer wall surface is not sufficiently insulated, and if heating is stopped, it will naturally cool to the outside air temperature.

温度が下がるので、十分外気から吸熱することができ
る。FIG. 2 is a heating cycle diagram (A → B → C → D → E → A) in the case of the present invention in which MH1, MH2, and MH3 are added. Its function is as described in the item of function already.
Starting from the standby state where most of the hydrogen is stored, the hydrogen moves rapidly from MH2 to MH1 when valve 6 is opened when rapid heating is required, and MH1 is about 19 kcal.
Generate fever. At this time, since the temperature of MH2 drops to the endothermic temperature T C (−10 degrees), heat can be sufficiently absorbed from the outside air.
反応終了後はまず弁６を閉じ、弁４を開くとMH1の水
素の一部がMH3へ移動する。この反応によってMH1は冷却
するので、せっかく暖めたものを又冷やすことになるか
ら、室内温度が上がってから徐々に水素をMH3に移動す
るよう弁の開度などを調整する必要がある。After completion of the reaction, first, the valve 6 is closed and the valve 4 is opened, so that part of the hydrogen of MH1 moves to MH3. Since MH1 is cooled by this reaction, what has been warmed up will be cooled again. Therefore, it is necessary to adjust the opening degree of the valve so that hydrogen is gradually moved to MH3 after the room temperature rises.
MH3の量はMH1の量に比べて、15％程度であるから当然
全水素移動量の15％程度しか移動しない。反応の終わっ
たところで弁４を閉じ、弁５を開くと共に温水弁７を開
きMH3の加熱を始める。MH3がほぼ80度にまで暖められる
と、水素はMH2に移動し、やがてMH3は空の状態になる。
そこで今度は弁５を閉じ弁４を開き、温水弁７を閉じる
とMH3は次第に冷却し再びMH1からMH3への水素の移動が
始まる。Since the amount of MH3 is about 15% compared to the amount of MH1, naturally only about 15% of the total hydrogen transfer amount is transferred. At the end of the reaction, valve 4 is closed, valve 5 is opened and hot water valve 7 is opened to start heating MH3. When MH3 is warmed up to almost 80 degrees, hydrogen moves to MH2 and eventually MH3 becomes empty.
Then, this time, when the valve 5 is closed and the valve 4 is opened and the hot water valve 7 is closed, the MH3 is gradually cooled and the transfer of hydrogen from MH1 to MH3 starts again.
以下同様な手順を７〜８回繰り返すと、MH1の水素は
ほとんど完全にMH2に移動し、元のスタンバイの常態に
戻る。When the same procedure is repeated 7 to 8 times, the hydrogen in MH1 almost completely moves to MH2 and returns to the original standby state.
以上一実施例について説明したが、MH3の加熱方法や
容器の形態等については、ここにあげた例に拘束される
ものではない。又MH3の量をさらに少なくすることもも
ちろん可能である。Although one embodiment has been described above, the method of heating MH3, the form of the container, and the like are not limited to the examples given here. It is of course possible to further reduce the amount of MH3.
またMH3とMH1を幾分異なる材料としたが、これは加熱
温度の都合上こうしたもので、同一材料でも勿論この発
明は成立する。又金属水素化物−水素系の例を挙げた
が、他の吸着材−被吸着気体の組合せでも良い事はいう
までもない。Also, MH3 and MH1 are made of slightly different materials, but this is because of the heating temperature, and the same material can of course be applied to the present invention. Further, although the example of the metal hydride-hydrogen system is given, it goes without saying that another adsorbent-adsorbed gas combination may be used.
（発明の効果） 以上説明したように、通常の２種類の吸着媒体の間を
被吸着媒体が移動して、吸熱、発熱を繰り返すシステム
では、第一の容器（MH1）に加熱装置が付加されなけれ
ばならない。しかし本発明による第一の容器は金属水素
化物を収容している以外に何等の付属物をも持たないた
め熱容量が小さく反応熱が有効に利用できるばかりでな
く加熱速度も早く、急速加熱器としての特性をいかんな
く発揮することができる。(Effects of the Invention) As described above, in the system in which the medium to be adsorbed moves between the two ordinary types of adsorption medium to repeat heat absorption and heat generation, a heating device is added to the first container (MH1). There must be. However, since the first container according to the present invention does not have any accessories other than containing the metal hydride, it has a small heat capacity, the reaction heat can be effectively utilized, and the heating rate is fast, so that it can be used as a rapid heater. The characteristics of can be exhibited without any limitation.
また第一の容器（MH1）に加熱装置を設け再生時に加
熱を行う様にすると、装置が大掛かりとなり目的の場所
に組み込めない可能性があるばかりでなく、被加熱部の
温度が上がりすぎて不都合を生ずる場合が多い。例えば
先に述べた実施例の場合、ハンドルが熱くなりすぎて使
用できなくなる。しかし本発明によれば再生時にはむし
ろ逆に幾分温度が低下するが、室温が上がってから徐々
に水素を移動させるように調整して置けば、なんら使用
に差し支えない。Also, if a heating device is installed in the first container (MH1) and heating is performed during regeneration, not only may the device become too large to be installed in the intended location, but the temperature of the heated part will rise too much, which is inconvenient. Often occurs. For example, in the case of the embodiment described above, the handle becomes too hot to be used. However, according to the present invention, the temperature is rather lowered during regeneration, but if the temperature is adjusted so that hydrogen is gradually moved after the temperature rises, it may be used.
本発明はMH1とMH2以外にMH3を使用するのでその分コ
スト高になるが、MH3の使用量はMH1より十分少なくして
あるので、全体のコストに及ぼす影響は少ない。In the present invention, since MH3 is used in addition to MH1 and MH2, the cost increases accordingly, but since the amount of MH3 used is sufficiently smaller than that of MH1, it has little effect on the overall cost.
このように気体の吸脱着加熱サイクルの蓄熱性を利用
した急速加熱器の再生過程を簡単な補助吸着部（MH3）
の付加で実用性を高めることができるので、種々の分野
に応用ができる。In this way, the regeneration process of the rapid heater utilizing the heat storage property of the gas adsorption / desorption heating cycle can be used as a simple auxiliary adsorption part (MH3).
Since it is possible to enhance the practicality by adding, it can be applied to various fields.
