【発明の属する技術分野】
本発明は可搬性に富み、採暖機能を有する燃焼熱の熱搬送装置に関するものである。
【０００２】
【従来の技術】
従来、この種の熱搬送装置は、図８に示すように、浴槽本体９の湯を湧かすため、循環水路１０で風呂釜本体１１の熱交換器１２と接続し、循環水路１０には強制循環するためのポンプ１３を設け、さらに加熱されて発電する熱発電素子１４は高温側となる受熱部１５をバーナ１６の燃焼炎に近接させ、その尾端部１７を低温側にして冷却するため、ポンプ１３から循環水路１０とは分岐して設けたバイパス送水路１８に接触させて設けられ、この熱発電素子１４は配線１９でポンプ１３に接続するように構成されていた。
【０００３】
上記構成において、浴槽本体９の湯を湧かす場合はバーナ１６を燃焼させると熱交換器１２で温水に加熱すると同時に、熱発電素子１４の受熱部１５がバーナ１６の燃焼熱で高温側として加熱され、その尾端部１７は分岐して設けたバイパス送水路１８で低温側として冷却されるため、温度差ができ、熱発電素子１４はゼーベック効果により発電する。そして発生電力は配線１９でポンプ１３に供給されてポンプ１３を駆動し、浴槽本体９の湯を循環していた。
【０００４】
【発明が解決しようとする課題】
しかしながら上記のような従来の装置では、熱発電素子１４の発電でポンプ１３を駆動するが、熱発電素子１４の発電効率は高温側と低温側の温度差で決定されるもので、バーナ１６の燃焼による温度と浴槽本体９のお湯の温度では一般的に数パーセント以下と低いものである。そこで浴槽本体９から循環水路１０を経由して熱交換器１２に循環させるポンプ１３の駆動電力を発電するには多量の熱発電素子１４を要するという課題があった。そのうえ、バーナ１６の熱量の大部分は直接、素交換器１２を加熱して浴槽本体９から循環水路１０を経由して熱交換器１２に流入した温水を加熱するため、熱発電素子１４を加熱する熱量は低い割合となり、したがって発生電力はポンプ１３の駆動電力よりも小さいため駆動できないとか、循環水路１０を経由して熱交換器１２への循環流量が不足するという課題を有していた。また、熱発電素子１４はその受熱部１５を高温側にしてバーナ１６に近接させて加熱し尾端部１７を低温側にして冷却するため、位置の制約から循環水路１０に直接固定できず、ポンプ１３からの循環水路１０とは別途分岐して設けたバイパス送水路１８に尾端部１７を固定して冷却しているため、構成が複雑になるという課題を有していた。さらに位置の制約から熱発電素子１４は取り付けれる量が限られ、前述と同様にポンプ１３を駆動するには発生電力が不足するとか、循環水路１０の循環流量が不足するという課題も有していた。
【０００５】
【課題を解決するための手段】
本発明は上記課題を解決するために、燃焼手段と、この燃焼手段の熱を高温側面に受熱して熱起電力を発生する熱電気変換素手段と、燃焼手段から受熱し、熱交換する熱交換手段と、電力で駆動して熱媒を熱交換手段へ搬送し、熱交換させる熱媒強制循環手段と、一端を熱媒強制循環手段に接続し、他端を熱交換手段に接続して熱交換手段で熱交換した熱媒を循環させて放熱する放熱手段と、熱電気変換手段の発生電力を蓄電する蓄電手段と、この蓄電手段の蓄電が所定値に達すると放電させ熱媒強制循環手段を駆動する蓄放電制御手段とから構成したものである。
【０００６】
上記発明によれば、燃焼手段に燃焼させると、この燃焼手段の燃焼熱を熱電気変換手段は高温側面に受熱し高温となる。さらに熱は熱交換手段へ伝熱する。熱電気変換手段は高温側面と低温側面との温度差に応じた電力を発生する。蓄電手段は熱電気変換手段の発生電力を蓄電する。蓄放電制御手段はこの蓄電手段の蓄電が所定値に達すると放電させ熱媒強制循環手段を駆動する。そして熱媒強制循環手段は駆動して熱媒を熱交換手段へ搬送し、伝わった燃焼手段の熱を熱媒と熱交換させる。さらに熱媒は放熱手段に循環し放熱して熱媒強制循環手段に戻り、熱搬送ができる。燃焼手段は放電することで蓄電が徐々に減少し、やがて放電電力が熱媒強制循環手段の駆動電力以下まで低下すると、蓄放電制御手段は放電を停止させて再び、熱電気変換手段の発生電力を蓄電させ、以降この動作を繰り返して運転が行われる。
【０００７】
さらに、蓄電手段が熱電気変換手段の発生電力を蓄電し、蓄放電制御手段がこの蓄電手段の蓄電が所定値に達すると放電させ熱媒強制循環手段を駆動するため、熱媒強制循環手段の駆動電力相当の電力を常時、発電する必要がなく、熱電気変換手段は少量、小型でよい。また、燃焼手段の燃焼熱量が変動し、発生電力が少ない方向に変動しても熱媒強制循環手段を駆動することができる。
【０００８】
【発明の実施の形態】
本発明は燃焼手段と、この燃焼手段の熱を高温側面に受熱して熱起電力を発生する熱電気変換素手段と、前記燃焼手段から受熱し、熱交換する熱交換手段と、電力で駆動して熱媒を前記熱交換手段へ搬送し、熱交換させる熱媒強制循環手段と、一端を前記熱媒強制循環手段に接続し、他端を前記熱交換手段に接続して前記熱交換手段で熱交換した熱媒を循環させて放熱する放熱手段と、前記熱電気変換手段の発生電力を蓄電する蓄電手段と、この蓄電手段の蓄電が所定値に達すると放電させ、熱媒強制循環手段を駆動する蓄放電制御手段とを有するものである。
【０００９】
そして、燃焼手段を燃焼させると、この燃焼手段の燃焼熱を熱電気変換手段は高温側面に受熱し高温になる。さらに熱は熱交換手段へ伝熱する。熱電気変換手段は高温側面と低温側面との温度差に応じた電力を発生する。蓄電手段は熱電気変換手段の発生電力を蓄電する。蓄放電制御手段はこの蓄電手段の蓄電が所定値に達すると放電させ熱媒強制循環手段を駆動する。
【００１０】
そして蓄電手段が熱電気変換手段の発生電力を蓄電し、蓄放電制御手段がこの蓄電手段の蓄電が所定値に達すると放電させ熱媒強制循環手段を駆動するため、熱媒強制循環手段の駆動電力相当の電力を常時、発電する必要がなく、熱電気変換手段は少量、小型でよい。また、燃焼手段の燃焼熱量が変動し、発生電力が少ない方向に変動しても熱媒強制循環手段を駆動することができる。
【００１１】
また、燃焼手段と、この燃焼手段の熱を高温側面に受熱し、その熱を低温側面から熱交換手段へ伝熱することで冷却され、高温側面と低温側面との温度差に応じた電力を発生する熱電気変換手段と、この熱電気変換素手段の低温側面から受熱し、熱媒に熱交換する熱交換手段と、前記熱電気変換手段の発生電力により駆動して熱媒を前記熱交換手段へ搬送し、熱電気変換手段を介して伝わった燃焼手段の熱を熱媒と熱交換させる熱媒強制循環手段と、一端を前記熱媒強制循環手段に接続し、他端を前記熱交換手段に接続して前記熱交換手段で熱交換した熱媒を循環させて放熱する放熱手段と、前記熱電気変換素手段の発生電力を蓄電する蓄電手段と、この蓄電手段の蓄電が所定値に達すると放電させ前記熱媒強制循環手段を駆動する蓄放電制御手段とを有するものである。
【００１２】
そして、燃焼手段を燃焼させると熱電気変換手段が高温側面に受熱し高温になる。さらに熱は熱電気変換手段の高温側面から低温側面へ伝わり、熱交換手段へ伝熱する。熱電気変換手段の低温側面は熱交換手段へ伝熱することで冷却されるため、熱電気変換手段は高温側面と低温側面との温度差に応じた電力を発生する。蓄電手段は熱電気変換手段の発生電力を蓄電する。蓄放電制御手段はこの蓄電手段の蓄電が所定値に達すると放電させ熱媒強制循環手段を駆動する。そして熱媒強制循環手段は駆動して熱媒を熱交換手段へ搬送し、伝わった燃焼手段の熱を熱媒と熱交換させる。さらに熱媒は放熱手段に循環し放熱して熱媒強制循環手段に戻り、熱搬送ができる。燃焼手段は放電することで蓄電が徐々に減少し、やがて放電電力が熱媒強制循環手段の駆動電力以下まで低下すると、蓄放電制御手段は放電を停止させて再び、熱電気変換手段の発生電力を蓄電させ、以降この動作を繰り返して運転が行われる。そして、蓄電手段が熱電気変換手段の発生電力を蓄電し、蓄放電制御手段がこの蓄電手段の蓄電が所定値に達すると放電させ熱媒強制循環手段を駆動するため、熱媒強制循環手段の駆動電力相当の電力を常時、発電する必要がなく、熱電気変換手段は少量、小型でよい。また、燃焼手段の燃焼熱量が変動し、発生電力が少ない方向に変動しても熱媒強制循環手段を駆動することができる。さらに熱電気変換手段は燃焼手段の燃焼熱の大部分を高温側面に受熱し、低温側面から熱交換手段へ伝熱して熱媒を加熱すると同時に発電するため、従来のようにバーナの熱量の大部分が直接、熱交換器を加熱して温水に熱交換し、低い割合の熱量が熱発電素子を加熱する構成に比べ、発生電力が小さいためポンプが駆動できないとか、循環流量が不足することもなく、確実に熱媒強制循環手段を駆動できる。位置の制約から循環水路とは別途分岐したバイパス送水路を設けることもなく、構成が簡単になり、大きく発電するだけの熱電気変換手段を取り付けられ、前述同様に確実に熱媒強制循環手段を駆動できる。
【００１３】
また、熱電気変換素手段の発生電力を蓄わえ所定値に達する迄の間は電池の電力を通電させて熱媒強制循環手段を駆動し、熱電気変換素手段の発生電力を蓄電し、蓄電手段の蓄電が所定値に達すると電池の電力の通電を停止し、蓄わえた熱電気変換素手段の発生電力を放電させて熱媒強制循環手段を駆動するように制御する蓄放電制御手段を有するものである。
【００１４】
そして、燃焼手段を燃焼させると熱電気変換手段は高温側面に受熱し電力を発生するが、蓄電手段がこの発生電力を蓄電し、所定値に達する迄の間は電池の電力を通電させて熱媒強制循環手段を駆動させ、蓄電手段の蓄電が所定値に達すると電池の電力の通電を停止し、蓄わえた熱電気変換素手段の発生電力を放電させて熱媒強制循環手段を駆動するように蓄放電制御手段が制御する。熱媒強制循環手段は熱媒を熱交換手段へ搬送し、伝わった燃焼手段の熱を熱媒と熱交換させ、次に放熱手段に循環して放熱させ、さらに熱媒強制循環手段に戻り、熱搬送が行われる。蓄電手段は放電することで蓄電が徐々に減少し、やがて放電電力が熱媒強制循環手段の駆動電力以下まで低下すると、蓄放電制御手段は放電を停止させて再び、熱電気変換手段の発生電力を蓄電させ、電池の電力を通電させて熱媒強制循環手段を駆動する。以降この動作を繰り返して運転が行われる。そして、蓄電手段が発生電力を蓄電し、所定値に達する迄の間は電池の電力を通電させて熱媒強制循環手段を駆動させ、蓄電手段の蓄電が所定値に達すると電池の電力の通電を停止し、蓄わえた熱電気変換素手段の発生電力を放電させるため、熱媒強制循環手段の駆動電力相当の電力を常時、発電する必要がなく、熱電気変換手段は少量、小型でよい。また、燃焼手段の燃焼熱量が変動し、発生電力が少ない方向に変動しても熱媒強制循環手段を駆動することができる。そして、運転開始から即時に電池により熱媒強制循環手段を駆動することができ、効率よく熱搬送が行われる。
【００１５】
また、熱電気変換素手段の発生電力が所定値に達する迄の間は電池の電力を通電させて、熱電気変換素手段の発生電力と電池の電力の併用で熱媒強制循環手段を駆動し、熱電気変換素手段の発生電力が所定値に達すると電池の電力の通電を停止して、熱電気変換素手段の発生電力単独で放電させて熱媒強制循環手段を駆動するように制御する蓄放電制御手段を有するものである。
【００１６】
そして、燃焼手段を燃焼させると熱電気変換手段は高温側面に受熱し電力を発生するが、所定値に達する迄の間は熱電気変換素手段の発生電力と電池の電力の併用で熱媒強制循環手段を駆動し、熱電気変換素手段の発生電力が所定値に達すると電池の電力の通電を停止して、熱電気変換素手段の発生電力単独で放電させて熱媒強制循環手段を駆動するように蓄放電制御手段が制御する。熱媒強制循環手段は熱媒を熱交換手段へ搬送し、伝わった燃焼手段の熱を熱媒と熱交換させ、次に放熱手段に循環して放熱させ、さらに熱媒強制循環手段に戻り、熱搬送が行われる。熱電気変換手段の発生電力が低下して所定値以下になると、再び熱電気変換素手段の発生電力と電池の電力の併用で熱媒強制循環手段を駆動するように制御される。以降この動作を繰り返して運転が行われる。そして、
熱電気変換素手段の発生電力が所定値に達する迄の間は熱電気変換素手段の発生電力と電池の電力の併用で熱媒強制循環手段を駆動し、熱電気変換素手段の発生電力が所定値に達すると、熱電気変換素手段の発生電力単独で放電させて熱媒強制循環手段を駆動するため、熱媒強制循環手段の駆動電力相当の電力を常時、発電する必要がなく、熱電気変換手段は少量、小型でよい。また、燃焼手段の燃焼量が変動し、発生電力が少ない方向に変動しても熱媒強制循環手段を駆動することができる。そして、運転開始から即時に電池により熱媒強制循環手段を駆動することができ、効率よく熱搬送が行われる。
【００１７】
また、熱媒強制循環手段への通電回路に昇圧手段を設け、熱電気変換素手段の発生電力の電圧よりも高い駆動電圧を必要とする熱媒強制循環手段に対し、駆動電圧以上に昇圧することで駆動を可能とする蓄放電制御手段を有するものである。
【００１８】
そして、燃焼手段を燃焼させると熱電気変換手段は高温側面に受熱し電力を発生するが、蓄電手段がこの発生電力を蓄電し、所定値に達すると蓄わえた発生電力を昇圧手段に放電させる。もしくは熱電気変換手段の発生電力とか電池の電力を直接に昇圧手段に通電する。昇圧手段はこれらの電力を昇圧し熱電気変換素手段の発生電力の電圧もしくは電池の電圧よりも高い駆動電力を必要とする熱媒強制循環手段に対し、駆動電圧以上に昇圧することで駆動を可能とする。熱媒強制循環手段は熱媒を熱交換手段へ搬送し、伝わった燃焼手段の熱を熱媒と熱交換させ、次に放熱手段に循環して放熱させ、さらに熱媒強制循環手段に戻り、熱搬送が行われる。そして、一般的には熱電気変換手段の発生電圧は数ボルト以下であるが熱媒強制循環手段の駆動電圧より低くても駆動できる。

BACKGROUND OF THE INVENTION
The present invention relates to a heat transfer device for combustion heat that is portable and has a warming function.
[0002]
[Prior art]
Conventionally, as shown in FIG. 8, this type of heat transfer device is connected to theheat exchanger 12 of the bathtub main body 11 through thecirculation water channel 10 in order to generate hot water in the bathtub body 9, and is forced to thecirculation water channel 10. A thermoelectricpower generation element 14 that is provided with a circulatingpump 13 and generates power by being heated is used to cool theheat receiving portion 15 on the high temperature side close to the combustion flame of theburner 16 and the tail end portion 17 on the low temperature side. The thermoelectricpower generation element 14 is configured to be connected to thepump 13 via a wiring 19 provided in contact with a bypass water supply path 18 that is branched from thepump 13 to thecirculation water path 10.
[0003]
In the above configuration, when the hot water of the bathtub main body 9 is spouted, when theburner 16 is burned, theheat exchanger 12 heats it to warm water, and at the same time, theheat receiving portion 15 of thethermoelectric generator 14 is heated to the high temperature side by the combustion heat of theburner 16. Then, the tail end portion 17 is cooled as a low temperature side by a bypass water passage 18 provided in a branched manner, so that there is a temperature difference, and thethermoelectric generator 14 generates power by the Seebeck effect. The generated power is supplied to thepump 13 through the wiring 19 to drive thepump 13 and circulate the hot water in the bathtub body 9.
[0004]
[Problems to be solved by the invention]
However, in the conventional apparatus as described above, thepump 13 is driven by the power generation of thethermoelectric generator 14. The power generation efficiency of thethermoelectric generator 14 is determined by the temperature difference between the high temperature side and the low temperature side. The temperature due to combustion and the temperature of the hot water in the bathtub body 9 are generally as low as several percent or less. Therefore, there is a problem that a large amount ofthermoelectric generators 14 are required to generate the driving power of thepump 13 that is circulated from the bathtub body 9 to theheat exchanger 12 via the circulatingwater channel 10. In addition, most of the heat quantity of theburner 16 directly heats thethermoelectric generator 14 in order to heat theelement exchanger 12 and heat the hot water flowing into theheat exchanger 12 from the bathtub body 9 via thecirculation water channel 10. Therefore, there is a problem that the generated heat is smaller than the driving power of thepump 13 and cannot be driven, or the circulating flow rate to theheat exchanger 12 via the circulatingwater channel 10 is insufficient. Further, since thethermoelectric generator 14 is cooled by setting theheat receiving portion 15 to the high temperature side to be close to theburner 16 and heating the tail end portion 17 to the low temperature side, it cannot be directly fixed to the circulatingwater channel 10 due to position restrictions. Since the tail end portion 17 is fixed and cooled in a bypass water supply passage 18 provided separately from thecirculation water passage 10 from thepump 13, the configuration is complicated. Furthermore, the amount of thethermoelectric generator 14 that can be attached is limited due to position restrictions, and there is a problem that the generated power is insufficient to drive thepump 13 as described above, or the circulating flow rate of the circulatingwater channel 10 is insufficient. It was.

DETAILED DESCRIPTION OF THE INVENTION
The present invention relates to a combustion means, a thermoelectric conversion element means for generating heat electromotive force by receiving heat of the combustion means on a high temperature side surface, a heat exchange means for receiving heat from the combustion means and exchanging heat, and driving with electric power. A heat medium forced circulation means for conveying the heat medium to the heat exchange means and exchanging heat; one end connected to the heat medium forced circulation means; the other end connected to the heat exchange means and the heat exchange means Heat radiating means for circulating and dissipating the heat medium exchanged in the heat, power storage means for storing the electric power generated by the thermoelectric conversion means, and discharging when the power stored in the power storage means reaches a predetermined value, forcing the heat medium to circulate And storage / discharge control means for driving.
[0009]
When the combustion means is combusted, the thermoelectric conversion means receives the combustion heat of the combustion means on the high temperature side surface and becomes high temperature. Furthermore, heat is transferred to the heat exchange means. The thermoelectric conversion means generates electric power according to the temperature difference between the high temperature side surface and the low temperature side surface. The power storage means stores the electric power generated by the thermoelectric conversion means. The storage / discharge control means discharges when the power stored in the power storage means reaches a predetermined value, and drives the heat medium forced circulation means.
[0010]
The power storage means stores the electric power generated by the thermoelectric conversion means, and the storage / discharge control means discharges when the power storage of the power storage means reaches a predetermined value and drives the heat medium forced circulation means. There is no need to constantly generate electric power equivalent to electric power, and the thermoelectric conversion means may be small and small. Further, the heat medium forced circulation means can be driven even if the combustion heat quantity of the combustion means fluctuates and the generated power fluctuates in a direction that decreases.
[0011]
In addition, the combustion means and the heat of the combustion means are received by the high temperature side surface, and the heat is transferred from the low temperature side surface to the heat exchange means to be cooled, and electric power corresponding to the temperature difference between the high temperature side surface and the low temperature side surface is generated. The generated thermoelectric conversion means, the heat exchange means that receives heat from the low temperature side surface of the thermoelectric conversion element means, and exchanges heat with the heat medium, and is driven by the generated electric power of the thermoelectric conversion means to exchange the heat medium with the heat medium. A heat medium forced circulation means for exchanging heat of the combustion means conveyed to the means through the thermoelectric conversion means with the heat medium, one end connected to the heat medium forced circulation means, and the other end to the heat exchange A heat dissipating means for circulating and dissipating heat from the heat exchange medium connected to the heat exchanging means, an accumulating means for accumulating electric power generated by the thermoelectric conversion element means, and the accumulating power of the accumulating means reaches a predetermined value A storage / discharge system that discharges when it reaches and drives the heat medium forced circulation means And has a means.
[0012]
And if a combustion means is burned, a thermoelectric conversion means will receive heat at a high temperature side surface, and will become high temperature. Furthermore, heat is transferred from the high temperature side surface to the low temperature side surface of the thermoelectric conversion means, and is transferred to the heat exchange means. Since the low temperature side surface of the thermoelectric conversion means is cooled by transferring heat to the heat exchange means, the thermoelectric conversion means generates electric power according to the temperature difference between the high temperature side surface and the low temperature side surface. The power storage means stores the electric power generated by the thermoelectric conversion means. The storage / discharge control means discharges when the power stored in the power storage means reaches a predetermined value, and drives the heat medium forced circulation means. The heat medium forced circulation means is driven to convey the heat medium to the heat exchange means, and exchanges the heat of the transmitted combustion means with the heat medium. Further, the heat medium circulates to the heat radiating means, radiates heat, returns to the heat medium forced circulation means, and can carry heat. When the combustion means discharges, the stored electricity gradually decreases, and when the discharge power eventually falls below the drive power of the heat medium forced circulation means, the storage / discharge control means stops the discharge and again generates power generated by the thermoelectric conversion means. Is stored, and this operation is repeated thereafter for operation. Then, the power storage means stores the electric power generated by the thermoelectric conversion means, and the storage / discharge control means discharges when the power storage of the power storage means reaches a predetermined value and drives the heat medium forced circulation means. There is no need to constantly generate power equivalent to drive power, and the thermoelectric conversion means may be small and small. Further, the heat medium forced circulation means can be driven even if the combustion heat quantity of the combustion means fluctuates and the generated power fluctuates in a direction that decreases. Furthermore, since the thermoelectric conversion means receives most of the combustion heat of the combustion means on the high temperature side, transfers heat from the low temperature side to the heat exchange means and heats the heating medium at the same time as generating electricity, the amount of heat of the burner is large as before. The part directly heats the heat exchanger and exchanges heat with hot water. Compared with the configuration in which a low proportion of heat heats the thermoelectric generator, the generated power is small and the pump cannot be driven, or the circulation flow rate may be insufficient. And the heat medium forced circulation means can be driven reliably. Due to location restrictions, there is no need to provide a bypass waterway that is branched separately from the circulation waterway, the configuration is simplified, and thermoelectric conversion means that can generate large amounts of electricity can be installed. Can drive.
[0013]
In addition, the electric power of the battery is energized to drive the heating medium forced circulation means until the electric power generated by the thermoelectric conversion means reaches a predetermined value, and the electric power generated by the thermoelectric conversion means is stored, Storage / discharge control means for controlling energization of the battery power to stop when the power stored in the power storage means reaches a predetermined value, and discharging the generated electric power of the thermoelectric conversion element means to drive the heat medium forced circulation means It is what has.
[0014]
When the combustion means is combusted, the thermoelectric conversion means receives heat on the high temperature side surface and generates electric power, but the electric storage means stores this generated electric power and energizes the battery power until it reaches a predetermined value. The medium forced circulation means is driven, and when the electricity stored in the power storage means reaches a predetermined value, the energization of the battery is stopped, and the generated electric power of the thermoelectric conversion element means is discharged to drive the heat medium forced circulation means. Thus, the storage / discharge control means controls. The heat medium forced circulation means conveys the heat medium to the heat exchange means, exchanges heat of the transmitted combustion means with the heat medium, then circulates to the heat dissipation means to radiate heat, and returns to the heat medium forced circulation means, Heat transfer is performed. When the power storage means is discharged, the power storage gradually decreases, and when the discharge power eventually drops below the drive power of the heat medium forced circulation means, the storage / discharge control means stops the discharge and again generates power generated by the thermoelectric conversion means. Is stored, and the electric power of the battery is energized to drive the heat medium forced circulation means. Thereafter, the operation is repeated by repeating this operation. The power storage means stores the generated power and energizes the battery until the predetermined value is reached to drive the heat medium forced circulation means. When the power storage means reaches the predetermined value, the battery power is supplied. And the stored electric power generated by the thermoelectric conversion element means is discharged. Therefore, it is not always necessary to generate electric power equivalent to the driving power of the heat medium forced circulation means, and the thermoelectric conversion means may be small and small in size. . Further, the heat medium forced circulation means can be driven even if the combustion heat quantity of the combustion means fluctuates and the generated power fluctuates in a direction that decreases. And a heat medium forced circulation means can be driven with a battery immediately from the start of operation, and heat transfer is performed efficiently.
[0015]
Further, the electric power of the battery is energized until the generated electric power of the thermoelectric conversion element means reaches a predetermined value, and the heat medium forced circulation means is driven by the combined use of the generated electric power of the thermoelectric conversion element means and the electric power of the battery. When the generated electric power of the thermoelectric converter means reaches a predetermined value, the energization of the battery is stopped, and the generated electric power of the thermoelectric converter means is discharged alone to drive the heat medium forced circulation means. It has a storage / discharge control means.
[0016]
When the combustion means is combusted, the thermoelectric conversion means receives the heat on the high temperature side surface and generates electric power. However, until the predetermined value is reached, the heat medium is forced by using both the electric power generated by the thermoelectric conversion element means and the electric power of the battery. When the circulating means is driven and the electric power generated by the thermoelectric conversion element reaches a predetermined value, the energization of the battery is stopped, and the electric power generated by the thermoelectric conversion element alone is discharged to drive the heating medium forced circulation means. Thus, the storage / discharge control means controls. The heat medium forced circulation means conveys the heat medium to the heat exchange means, exchanges heat of the transmitted combustion means with the heat medium, then circulates to the heat dissipation means to radiate heat, and returns to the heat medium forced circulation means, Heat transfer is performed. When the electric power generated by the thermoelectric conversion means decreases to a predetermined value or less, the heat medium forced circulation means is again driven by using the electric power generated by the thermoelectric conversion element means and the battery power again. Thereafter, the operation is repeated by repeating this operation. And
Until the generated power of the thermoelectric converter means reaches a predetermined value, the heat medium forced circulation means is driven by the combined use of the generated power of the thermoelectric converter means and the power of the battery, and the generated power of the thermoelectric converter means is reduced. When the predetermined value is reached, the electric power generated by the thermoelectric conversion element means is discharged alone to drive the heat medium forced circulation means, so there is no need to constantly generate electric power equivalent to the drive power of the heat medium forced circulation means. The electrical conversion means may be small and small. Further, the heat medium forced circulation means can be driven even if the combustion amount of the combustion means fluctuates and the generated power fluctuates in a direction that decreases. And a heat medium forced circulation means can be driven with a battery immediately from the start of operation, and heat transfer is performed efficiently.
[0017]
Further, a boosting means is provided in the energization circuit to the heat medium forced circulation means, and the heat medium forced circulation means that requires a drive voltage higher than the voltage of the electric power generated by the thermoelectric converter means is boosted to the drive voltage or higher. Thus, a storage / discharge control means that can be driven is provided.
[0018]
When the combustion means is combusted, the thermoelectric conversion means receives heat on the high temperature side surface and generates electric power. The electric storage means stores this generated electric power, and when the predetermined value is reached, the stored generated electric power is discharged to the boosting means. . Alternatively, the boosting means is directly energized with the electric power generated by the thermoelectric conversion means or the electric power of the battery. The boosting means boosts these powers to boost the heating medium forced circulation means that requires a driving power higher than the voltage of the electric power generated by the thermoelectric converter means or the voltage of the battery by driving it above the driving voltage. Make it possible. The heat medium forced circulation means conveys the heat medium to the heat exchange means, exchanges heat of the transmitted combustion means with the heat medium, then circulates to the heat dissipation means to radiate heat, and returns to the heat medium forced circulation means, Heat transfer is performed. In general, the generated voltage of the thermoelectric conversion means is several volts or less, but it can be driven even if it is lower than the drive voltage of the heat medium forced circulation means.

[0026]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
Next, the operation and action will be described. When the combustion means 2 is burned, the thermoelectric conversion means 20 receives heat at the hightemperature side surface 21 and becomes high temperature. Further, the heat is transferred from the hightemperature side surface 21 of the thermoelectric conversion means 20 to the lowtemperature side surface 22 and is transferred to the heat exchange means 3. Since the lowtemperature side surface 22 of the thermoelectric conversion means 20 is cooled by transferring heat to the heat exchange means 3, the thermoelectric conversion means 20 generates electric power according to the temperature difference between the hightemperature side surface 21 and the lowtemperature side surface 22. The power storage means 23 stores the electric power generated by the thermoelectric conversion means 20. The storage / discharge control means 24 is discharged when the power stored in the power storage means 23 reaches a predetermined value, and drives the heat medium forced circulation means 4. The heat medium forced circulation means 4 is driven to convey the heat medium to the heat exchanging means 3 and exchange the heat of the transferred combustion means 2 with the heat medium. Further, the heat medium circulates in the heat radiating means 8 and radiates heat to return to the heat medium forced circulation means 4 so that heat can be transferred. When the power storage means 13 discharges, the power storage gradually decreases, and when the discharge power eventually drops below the driving power of the heat medium forced circulation means 4, the storage / discharge control means 24 stops the discharge and again the thermoelectric conversion means.

There is no need to constantly generate power corresponding to the drive power of the medium forced circulation means 4, and the thermoelectric conversion means 20 may be small and small. Further, the heat medium forced circulation means 4 can be driven even if the combustion heat quantity of the combustion means 2 fluctuates and fluctuates in a direction where the generated power is small. Further, since the thermoelectric conversion means 20 receives most of the combustion heat of the combustion means 2 on the hightemperature side surface 21 and transfers heat from the lowtemperature side surface 22 to the heat exchange means 3 to heat the heat medium and simultaneously generate power, Most of the heat quantity of theburner 16 directly heats theheat exchanger 12 and exchanges heat with warm water, and thepump 13 cannot be driven because the generated power is smaller than that of the configuration in which the heat quantity of the low ratio heats thethermoelectric generator 14.

The power generated by the element means 20 is stored, and when the power stored in the power storage means 23 reaches a predetermined value, the energization of thebattery 5 is stopped, and the stored power generated by the thermoelectric conversion element means 20 is discharged to force the heat medium. The storage / discharge control means 24 for controlling the circulation means 4 to be driven is provided.
[0029]
In addition, the thing of the same code | symbol as Example 1 has the same structure, and abbreviate | omits description.
Next, the operation and action will be described. When the combustion means 2 is combusted, the thermoelectric conversion means 20 receives heat at the hightemperature side surface 21 and generates electric power, but the electric storage means 23 stores this generated electric power and energizes the electric power of thebattery 5 until it reaches a predetermined value.

In addition, there is an advantageous effect that the heat medium forced circulation means can be driven even if the amount of combustion heat of the combustion means fluctuates and the generated power fluctuates in a direction that decreases. Furthermore, since the thermoelectric conversion means receives most of the combustion heat of the combustion means on the high temperature side, transfers heat from the low temperature side to the heat exchange means and heats the heating medium at the same time as generating electricity, the amount of heat of the burner is large as before. The part directly heats the heat exchanger and exchanges heat with hot water. Compared with the configuration in which a low proportion of heat heats the thermoelectric generator, the generated power is small and the pump cannot be driven, or the circulation flow rate may be insufficient. And the heat medium forced circulation means can be driven reliably.

In addition, the thermoelectric conversion means has the advantageous effect of being small and small in size. In addition, there is an advantageous effect that the heat medium forced circulation means can be driven even if the amount of combustion heat of the combustion means fluctuates and the generated power fluctuates in a direction that decreases. The heat medium forced circulation means can be driven by the battery immediately after the operation is started, and there is an advantageous effect that heat transfer is performed efficiently. Compared to the case where the heat medium forced circulation means is driven only by a battery as in the prior art, there are advantageous effects that the frequency and labor of battery replacement are reduced, the cost of the battery is reduced, and it is economical. The heat medium forced circulation means can be driven by the battery immediately after the start of operation, and there is an advantageous effect that heat transfer is performed efficiently.
