Description
この発明は、フード付きの換気設備において、換気扇フード内上部に熱伝導が良い熱交換器を設置し、排気熱を利用して熱交換器内の循環水を温め、換気扇フード外部に設置した貯湯給湯機内の水を温める。そしてそのお湯を利用し今度は補助給湯機の給水を温める。また、換気扇フード内部の熱風を直接貯湯給湯機内に取り込み内部の水を再度温め、換気排気熱温度を下げる給湯装置に関するものである。 The present invention relates to a hooded ventilator, in which a heat exchanger having good heat conduction is installed in the upper part of the ventilation fan hood, the circulating water in the heat exchanger is warmed using exhaust heat, and the hot water storage installed outside the ventilation fan hood Warm the water in the water heater. The hot water is then used to warm up the auxiliary hot water supply. Further, the present invention relates to a hot water supply apparatus that takes in hot air inside a ventilation fan hood directly into a hot water storage hot water heater and warms the water inside again to lower the ventilation exhaust heat temperature.
従来あった装置は、換気扇フード内に貯水タンクがあり、タンクの外形寸法による貯水量や重量にも限界があった。また、排気熱が吸熱用フィン間を通過することによる熱交換であり、フィンの隙間の目詰まりによるトラブルが有ると考えられた。また、その熱交換後は、換気扇フード内の排気熱をそのまま室外へ排出していた。 The conventional apparatus has a water storage tank in the ventilation fan hood, and there is a limit to the amount of water stored and the weight depending on the external dimensions of the tank. Moreover, it was considered that there was a trouble due to clogging of the gaps between the fins because the heat of exhaust passed through between the heat absorption fins. Moreover, after the heat exchange, the exhaust heat in the ventilation fan hood was directly discharged outside the room.
従来の技術は、次のような欠点があった。
従来、換気扇フード内に貯水タンクがあり、ましてこの貯水タンクが天井や壁により支持固定されていることによりタンク形状には限界があり、貯水タンクの熱交換された湯を連続出湯するには限界があった。また、使用環境上熱交換フィンの目詰まりがある事は明らかに想像ができ、その掃除に関してもまた大変な労力を想像ができる。そして、排気熱をその後、換気口より室外に排出するだけでは、まだかなりの高温度の排気熱を大気中に排出していると考えられる。
本発明は、以上のような欠点をなくすためになされたものである。The conventional technology has the following drawbacks.
Conventionally, there is a water storage tank in the ventilation fan hood, and there is a limit to the shape of the tank because this water storage tank is supported and fixed by the ceiling and walls, and there is a limit to the continuous discharge of hot water from the water storage tank. was there. In addition, it can be clearly imagined that the heat exchange fins are clogged due to the usage environment, and it can also be imagined that much effort is required for cleaning the fins. Then, it is considered that exhaust heat at a considerably high temperature is still exhausted into the atmosphere by simply exhausting the exhaust heat from the ventilation port to the outside.
The present invention has been made to eliminate the above drawbacks.
調理器具等で排気熱が発生する部屋にフード（１）を設け、このフード（１）内に排気熱整流板（３）を設置して、前記フード（１）内を下部のフード排気熱対流室（８）と上部フード排気熱熱交換室（９）に区分する。そしてフード排気熱熱交換室（９）内にフード熱交換器（２）を設置する。フード熱交換器（２）内部のフード熱交換器循環パイプ（１０）のお湯は循環ポンプ（２６）により、フード（１）とは別の場所に置かれた給湯機缶体（１４）内部に組み込まれている給湯機熱交換管（２４）を通り、またフード熱交換器（２）へと戻って行く。給湯機熱交換管（２４）を通過する間に給湯機缶体（１４）の補助給湯機（４０）接続の給水を温める。 A hood (1) is provided in a room where exhaust heat is generated by a cooking utensil or the like, an exhaust heat rectifying plate (3) is installed in the hood (1), and the lower hood exhaust heat convection in the hood (1). It is divided into a chamber (8) and an upper hood exhaust heat heat exchange chamber (9). The hood heat exchanger (2) is installed in the hood exhaust heat heat exchange chamber (9). The hot water from the hood heat exchanger circulation pipe (10) in the hood heat exchanger (2) is placed inside the water heater can (14) placed at a location different from the hood (1) by the circulation pump (26). It passes through the built-in water heater heat exchange pipe (24) and returns to the hood heat exchanger (2). While passing through the water heater heat exchange pipe (24), the water supply connected to the auxiliary water heater (40) of the water heater can body (14) is warmed.
また、排気熱はフード熱交換器（２）に熱を奪われ、換気扇（５）を介して給湯機排気熱対流室（１６）へと導かれる。給湯機缶体（１４）の水中に設置してある缶体内排気熱熱交換管（３０）を通過する際、給湯機缶体（１４）の水と再び熱交換する。ここで、また排気熱を奪われることにより、さらに低い温度にて最終排気口（２０）より大気中へ排気放出される。出湯蛇口（４３）の出湯温度が不足の場合を考え、給湯機缶体出湯口（２２）を補助給湯機（４０）に接続し出湯蛇口（４３）からの出湯となる。本発明は以上の構成によりなる排気熱利用貯湯給湯機である。 Further, the exhaust heat is deprived of heat by the hood heat exchanger (2), and is led to the hot water heater exhaust heat convection chamber (16) through the ventilation fan (5). When passing through the can body exhaust heat heat exchange pipe (30) installed in the water of the water heater can body (14), heat exchange is performed again with the water in the water heater can body (14). Here, exhaust heat is also taken away, so that the exhaust is discharged into the atmosphere from the final exhaust port (20) at a lower temperature. Considering the case where the hot water temperature at the hot water tap (43) is insufficient, the hot water heater can hot water outlet (22) is connected to the auxiliary hot water heater (40) and the hot water from the hot water tap (43) is used. The present invention is an exhaust heat utilizing hot water storage hot water heater having the above configuration.
フード（１）内に設置したフード熱交換器（２）を掃除する手間を無くし、貯湯タンクをフード（１）外に設置することにより大量の貯湯を可能にした。調理機具等にて発生した排気熱温度をさらに下げ、大気中へ放出することを可能にした。また、一缶二水路方式の貯湯式缶体給湯機（２８）の構造にする事により、連続出湯及び、給水と同圧力出湯を可能にした。そして補助給湯機（４０）の給水温度を上げる事により、燃焼時間短縮による燃費の向上を可能にした。燃焼時間短縮は、補助給湯機（４０）が発する排気熱量削減にもつながり、排気ガスに含まれている環境汚染物質である、二酸化炭素削減を可能にしたのである。 By removing the trouble of cleaning the hood heat exchanger (2) installed in the hood (1), a large amount of hot water can be stored by installing a hot water storage tank outside the hood (1). The exhaust heat temperature generated in cooking utensils etc. can be further lowered and released into the atmosphere. In addition, by adopting the structure of a hot water storage can water heater (28) of a single can / two water channel system, continuous hot water and hot water with the same pressure as the hot water supply can be obtained. And by raising the feed water temperature of the auxiliary water heater (40), the fuel consumption can be improved by shortening the combustion time. The shortening of the combustion time also leads to a reduction in the amount of exhaust heat generated by the auxiliary hot water heater (40), and enables the reduction of carbon dioxide, which is an environmental pollutant contained in the exhaust gas.
一日中排気熱を発している業務用調理機具等において、大量の排気熱を大気中に排気放出している。この大量の排気熱を利用し同時に削減しながら、厨房出湯蛇口（４３）で必要の給湯を作り出すことに成功した。厨房出湯蛇口（４３）のみならず余った貯湯部分で他の給湯設備に使用することも可能にした。 A large amount of exhaust heat is exhausted to the atmosphere in a cooking utensil for business that emits exhaust heat all day. While using this large amount of exhaust heat and reducing it at the same time, we succeeded in creating the necessary hot water supply at the kitchen hot water tap (43). Not only the kitchen hot water tap (43) but also the remaining hot water storage can be used for other hot water facilities.
どのようにして、人間が作り出している熱である人工排熱の温度を下げるか。そして二酸化炭素を排出しないで生活するかが、地球上で大きな環境問題になっている。ヒートアイランド現象の要因の一つである人工排熱を減らすことにより、住みよい地球を後世に残していけるのである。 How to lower the temperature of artificial exhaust heat, which is the heat that humans are producing. Whether or not to live without emitting carbon dioxide has become a major environmental problem on the planet. By reducing artificial exhaust heat, which is one of the causes of the heat island phenomenon, we can leave a comfortable earth for future generations.
以下、本発明を実施するための形態ついて説明する
熱の排出が必要とされる部屋において、図４に示すようにフード（１）の下面にあるフード下面排気熱取り込み口（６）より入る排気熱の流れ（Ａ）と、フード側面排気熱取り込み口（７）より入る排気熱の流れ（Ｂ）がある。そのフード（１）内に排気熱整流板（３）を設けることにより、フード（１）を上下二つの部屋を設ける。下部をフード排気熱対流室（８）そして上部を、フード排気熱熱交換室（９）とする。このフード排気熱熱交換室（９）には、フード熱交換器（２）を水平に設置し、そしてフード熱交換器（２）とフード（１）内壁との間にはフード排気熱熱交換室の排気熱の流れ（Ｄ）が阻害されない空間を周りに保つ様に設置する。換気扇（５）の吸引力によりフード排気熱対流室（８）に集められた全ての排気熱は、フード排気熱対流室の排気熱の流れ（Ｃ）に示すように、排気熱整流板（３）の端にいったん集められてからフード排気熱熱交換室（９）へと流れ込んで行く。そして、必ず全ての排気熱は、フード熱交換器（２）の周りを通り、換気扇フード排気口（１３）から換気扇（５）を通り排気熱移動ダクト（４）へと導かれて行く。Hereinafter, in a room where heat discharge is required, which will be described with reference to the mode for carrying out the present invention, as shown in FIG. There is a heat flow (A) and an exhaust heat flow (B) entering from the hood side exhaust heat intake port (7). By providing the exhaust heat rectifying plate (3) in the hood (1), the hood (1) is provided in two upper and lower rooms. The lower part is the hood exhaust heat convection chamber (8) and the upper part is the hood exhaust heat heat exchange chamber (9). In this hood exhaust heat heat exchange chamber (9), the hood heat exchanger (2) is installed horizontally, and the hood exhaust heat heat exchange is provided between the hood heat exchanger (2) and the inner wall of the hood (1). It is installed so as to keep a space where the exhaust heat flow (D) of the chamber is not hindered. All exhaust heat collected in the hood exhaust heat convection chamber (8) by the suction force of the ventilating fan (5), as shown in the exhaust heat flow (C) in the hood exhaust heat convection chamber, is shown in FIG. ) Once collected at the end of the hood) and then flows into the hood exhaust heat heat exchange chamber (9). All the exhaust heat always passes around the hood heat exchanger (2), and is guided from the ventilation fan hood exhaust port (13) to the exhaust heat transfer duct (4) through the ventilation fan (5).
このフード熱交換器（２）の中部には、図５に記したように、フード熱交換器循環パイプ熱吸収板（３５）が、できる限り多くの熱を吸収できる様設置され、そして同じくフード熱交換器（２）内の熱を吸収する様にフード熱交換器循環パイプ（１０）が設置されてある。熱伝導体のフード熱交換器循環パイプ熱吸収板（３５）とフード熱交換器循環パイプ（１０）は溶接などにより密着されている。フード熱交換器循環パイプ（１０）自身も熱吸収の良い熱伝導体の材質からできており、形状も熱吸収効率の良い形になっている。このフード熱交換器循環パイプ（１０）は、図７に記すとおり太い部分（１０ａ）と細い部分（１０ｂ）とを繰り返し形成してあり、水が直線で素通りし流れるのではなく、連続の異径の管にすることにより、管内で対流を起こしながらぶつかり合い、管壁から熱を奪いながら流れる様にし、効率良く熱を貰えるよう表面積が広い形状となっているのである。この様にする事により周りの熱がいっそう吸収されるのである。又、フード熱交換器（２）は目詰まりのもととなる一般的に存在するフィンを無くし、フード熱交換器循環パイプ（１０）及び熱伝導体のフード熱交換器循環パイプ熱吸収板（３５）は、熱伝導体のケーシング（２ａ）の中に設置する事により掃除を無くす事に成功した。 As shown in FIG. 5, a hood heat exchanger circulation pipe heat absorption plate (35) is installed in the middle of the hood heat exchanger (2) so as to absorb as much heat as possible. A hood heat exchanger circulation pipe (10) is installed so as to absorb heat in the heat exchanger (2). The hood heat exchanger circulation pipe heat absorption plate (35) of the heat conductor and the hood heat exchanger circulation pipe (10) are in close contact by welding or the like. The hood heat exchanger circulation pipe (10) itself is also made of a heat conductor material having good heat absorption, and the shape is also good in heat absorption efficiency. This hood heat exchanger circulation pipe (10) has a thick portion (10a) and a thin portion (10b) formed repeatedly as shown in FIG. 7, and water does not flow straight but flows continuously. By making the pipes of diameter, they collide with each other while causing convection in the pipes, flow while taking heat away from the pipe wall, and have a large surface area so that heat can be efficiently received. By doing so, the surrounding heat is absorbed more. Also, the hood heat exchanger (2) eliminates the generally existing fins that cause clogging, and the hood heat exchanger circulation pipe (10) and the heat conductor hood heat exchanger circulation pipe heat absorption plate ( 35) succeeded in eliminating the cleaning by installing it in the casing (2a) of the heat conductor.
循環ポンプ（２６）の駆動により、そのフード熱交換器（２）内のフード熱交換器内循環パイプ（１０）内を循環水が通過する間に、排気熱から熱を奪うことにより作られたお湯は、フード熱交換器出湯口（１２）より出湯され、循環ポンプ（２６）を介して貯湯式缶体給湯機（２８）の給湯機熱交換管入湯口（２３）より給湯機熱交換管（２４）へと導かれて行く。給湯機熱交換管（２４）は給湯機缶体（１４）の水中を螺旋状に組み込んであり、材質はフード熱交換器循環パイプ（１０）と同じく、熱伝導体で図７に記した形状となっている。この給湯機熱交換管（２４）を循環湯が通過する間に、給湯機缶体（１４）の水との間で熱交換し、給湯機缶体（１４）の水を温めるのである。そして熱を奪われた循環水は、給湯機熱交換管出水口（２５）よりフード熱交換器入水口（１１）に接続されフード（１）内のフード熱交換器（２）内へと、再び戻って行くのである。 It was made by taking heat from the exhaust heat while circulating water passed through the circulation pipe (10) in the hood heat exchanger in the hood heat exchanger (2) by driving the circulation pump (26). Hot water is discharged from the hood heat exchanger outlet (12), and from the hot water storage heat exchanger pipe inlet (23) of the hot water storage can water heater (28) via the circulation pump (26). Go to (24). The water heater heat exchange pipe (24) incorporates the water of the water heater can body (14) in a spiral shape, and the material is the same as that of the hood heat exchanger circulation pipe (10), and the shape shown in FIG. It has become. While circulating hot water passes through the water heater heat exchange pipe (24), heat is exchanged with the water in the water heater can body (14) to warm the water in the water heater can body (14). And the circulating water deprived of heat is connected to the hood heat exchanger inlet (11) from the water heater heat exchange pipe outlet (25) and into the hood heat exchanger (2) in the hood (1). Go back again.
また、上記給湯機缶体（１４）の水は、補助給湯機（４０）の給水が貯まっているのであり、給湯機缶体給水管（２７）より給湯機缶体給水弁（４７）をへて、必ず減圧逆止弁（２９）にて水道圧力を０．８ｋｇ／ｃｍ２以下に落として給湯機缶体入水口（２１）より給湯機缶体（１４）へと、入水させることが義務付けられているのである。そして給湯機缶体（１４）の水は、循環水が通る給湯機熱交換管（２４）との間で熱交換されながら、徐々に温まっていくのである。図６に記すように温められた給湯機缶体（１４）の湯は、給湯機缶体出湯口（２２）より補助給湯機給水管（４１）に接続し、補助給湯機（４０）にて加温され、補助給湯機出湯管（４２）が出湯蛇口（４３）に接続され出湯されるのである。なお、図１の循環ポンプ（２６）は、厨房調理器具等より熱が発せられている間は、常時駆動し循環し続けて、給湯機缶体（１４）内部の貯湯水を常に加温しているのである。The water in the hot water heater can body (14) is stored in the auxiliary hot water heater (40), and the hot water heater can body water supply pipe (27) is passed through the hot water heater can body water supply valve (47). The water pressure must be reduced to 0.8 kg / cm 2 or less by the pressure reducing check valve (29), and water must enter the hot water can body (14) from the hot water can body water inlet (21). It is. Then, the water in the water heater can body (14) gradually warms up while exchanging heat with the water heater heat exchange pipe (24) through which the circulating water passes. The hot water of the water heater can body (14) warmed as shown in FIG. 6 is connected to the auxiliary water heater water supply pipe (41) from the water heater can body outlet (22), and the auxiliary water heater (40). After being heated, the auxiliary hot water supply outlet pipe (42) is connected to the outlet tap (43) and discharged. The circulation pump (26) in FIG. 1 is always driven and continuously circulated while heat is generated from the kitchen cooking utensil or the like, so that the hot water stored in the water heater can (14) is always heated. -ing
また、本発明のもう一つの特徴である換気排気熱利用は、フード（１）内だけの利用だけではない。すなわちフード熱交換器（２）にて熱を奪われながらもまだ温かい排気熱は、換気扇（５）を介し、排気熱移動ダクト（４）内を移動し、貯湯式缶体給湯機（２８）の下部に設けた給湯機排気熱対流室（１６）へと導かれる。その後、給湯機排気熱入口（１７）より、給湯機缶体（１４）の水中部に組み込まれている多数の缶体内熱交換管（３０）へと導かれて行く。なお、缶体内熱交換管（３０）の形状は、給湯機熱交換管（２４）と同じく図７に記した形状であり、給湯機缶体（１４）の水との間の熱交換効率を考えた形状となっている。その缶体内熱交換管（３０）内を排気熱が通過する際、給湯機缶体（１４）内に貯水されている水と、再び熱交換することになる。そして更に熱を奪われることとなり、前記多数の缶体内熱交換管（３０）から給湯機排気熱フード（１９）内の給湯機排気熱集合室（３２）に集められた排気熱は、換気扇フード排気口（１３）を通過する際の温度に比べ、二度の熱交換をしているのでさらに低い温度にて、最終排気口（２０）より大気中へ排気放出される事が本発明の特徴と言えるのである。
また、図１及び図２に記す貯湯式缶体給湯機（２８）のような据え置きタイプにすることにより、外形寸法には限界はないといえる。現場の必要給湯設備貯湯量から算出することができる。Further, the use of ventilation exhaust heat, which is another feature of the present invention, is not limited to the use only in the hood (1). That is, the exhaust heat that is still warm while being deprived of heat in the hood heat exchanger (2) moves through the exhaust heat transfer duct (4) through the ventilation fan (5), and the hot water storage can water heater (28). To the water heater exhaust heat convection chamber (16) provided at the lower part of the water heater. Then, it is led from the hot water heater exhaust heat inlet (17) to a large number of can heat exchange tubes (30) incorporated in the underwater portion of the hot water heater can (14). The shape of the heat exchange pipe (30) in the can is the shape shown in FIG. 7 as in the case of the water heater heat exchange pipe (24), and the heat exchange efficiency with the water in the water heater can (14) is improved. It is the shape that I thought. When the exhaust heat passes through the heat exchange pipe (30) in the can, the heat is again exchanged with the water stored in the water heater can (14). Further, the heat is further deprived, and the exhaust heat collected in the hot water exhaust heat collection chamber (32) in the hot water supply exhaust heat hood (19) from the large number of can internal heat exchange tubes (30) becomes the ventilation fan hood. Since the heat exchange is performed twice compared to the temperature when passing through the exhaust port (13), the exhaust gas is discharged from the final exhaust port (20) into the atmosphere at a lower temperature. It can be said.
Moreover, it can be said that there is no limit in an external dimension by setting it as a stationary type like the hot water storage type can water heater (28) described in FIG.1 and FIG.2. It can be calculated from the required hot water storage capacity at the site.
本発明の、排気熱利用貯湯給湯装置においては、出湯蛇口（４３）のお湯と、フード熱交換器循環パイプ（１０）と給湯機熱交換管（２４）を循環する排気熱利用の循環水とは絶対に混水しない、一缶二水路方式の装置となっているのである。又、この一缶二水路方式にすることによって、限りなく出湯蛇口（４３）からの出湯が可能なのである。これがもう一つの特徴でもある。以上が図１に記した排気熱利用貯湯給湯装置の形態の説明となる。 In the exhaust heat utilization hot water storage hot water supply apparatus of the present invention, hot water from the tap hot water tap (43), circulating water using exhaust heat circulating through the hood heat exchanger circulation pipe (10) and the water heater heat exchange pipe (24), Is a single-can two-channel system that never mixes water. Moreover, by using this one-can two-water channel system, the hot water can be discharged from the hot water tap (43) as much as possible. This is another feature. The above is description of the form of the exhaust heat utilization hot water storage hot water supply apparatus described in FIG.
前記で説明した中での減圧逆止弁（２９）の圧力０．８ｋｇ／ｃｍ２以上の出湯圧力が、出湯蛇口（４３）にて必要とされる環境においての説明となるのが、図２に記した排気熱利用貯湯給湯装置である。
出湯蛇口（４３）からの出湯圧が必要とされる場合においては、前記図１に示す一缶二水路方式の貯湯式缶体給湯機（２８）の配管接続を逆にする事により解決される。つまり図２に示す排気熱利用貯湯給湯装置ように、フード熱交換器（２）にて熱交換し温められたお湯を、循環ポンプ（２６）を介し貯湯式缶体給湯機（２８）の給湯機缶体循環入湯口（３３）に接続し、給湯機缶体（１４）内のお湯全てを循環水として利用すれば良いのである。しかし給湯機缶体（１４）への入水圧力は必ず減圧装置が必要とされるため、循環水給水管（３９）より給水される配管に減圧逆止弁（２９）を接続し、減圧してから給湯機缶体（１４）の給湯機缶体循環出水口（３４）へ接続される。そして給湯機缶体（１４）の水全部の貯湯されているお湯は、循環ポンプ（２６）にて常時、フード熱交換器（２）に戻し循環させることとなる。給湯機缶体（１４）の水中内に螺旋状に組み込まれた給湯機熱交換管（２４）には、給湯機熱交換管入水口（３６）より補助給湯機（４０）の給水側の水を通すことにより、給湯機缶体（１４）の内部で熱交換され温められた水は、給湯機熱交換管出湯口（３７）より出湯されるお湯となり、補助給湯機（４０）の補助給湯機給水管（４１）へ接続される。即ち給湯機熱交換管給水管（３８）より給水された水圧がそのまま補助給湯機給水管（４１）の水圧となり、出湯蛇口（４３）より出湯されるのである。したがって、後記に示した図２の排気熱利用貯湯給湯装置は、出湯蛇口（４３）にて給湯圧が必要とされる現場においては、有効な装置といえる。なお、図１及び図２に記されている給湯機缶体圧力安全弁（４６）は、減圧逆止弁（２９）のある接続缶体に取り付けが、義務付けられている安全装置である。そして貯湯式缶体給湯機（２８）とフード熱交換器（２）とを結ぶ循環配管に取り付けてある循環パイプ空気抜き弁（４５）は、循環水経路内に発生する空気を抜くことにより、循環ポンプ（２６）の空運転防止につながり熱効率向上にも大事な弁といえる。また、図２の排気熱利用貯湯給湯装置は、水の流れは前記図１の装置とは相違するが、排気熱は前記図１に示すとおりの同じ流れの効果となり、最終排気口（２０）より低温度にて大気中へと放出されるのである。
本発明は、以上の構成によりなる排気熱利用貯湯給湯機であるFIG. 2 is an explanation in an environment where a tapping pressure of 0.8 kg / cm 2 or more of the pressure reducing check valve (29) described above is required at the tapping tap (43). It is the hot water storage hot water supply apparatus using exhaust heat described in 1.
When the hot water pressure from the hot water tap (43) is required, it can be solved by reversing the piping connection of the hot water storage can water heater (28) of the single can / two water channel system shown in FIG. . That is, as in the exhaust heat utilizing hot water storage hot water supply apparatus shown in FIG. 2, the hot water heated and exchanged in the hood heat exchanger (2) is supplied to the hot water storage type hot water supply (28) through the circulation pump (26). It is only necessary to connect to the machine can body circulation hot water inlet (33) and use all the hot water in the water heater can body (14) as the circulating water. However, since a pressure reducing device is always required for the water pressure to enter the hot water can body (14), the pressure reducing check valve (29) is connected to the pipe supplied with water from the circulating water supply pipe (39) to reduce the pressure. To the hot water supply can body circulation outlet (34) of the hot water supply can body (14). The hot water stored in the hot water can body (14) is always returned to the hood heat exchanger (2) and circulated by the circulation pump (26). The water heater heat exchange pipe (24) spirally incorporated in the water of the water heater can body (14) has water on the water supply side of the auxiliary water heater (40) from the water heater heat exchange pipe inlet (36). By passing the water, the water heated and exchanged inside the water heater can body (14) becomes hot water discharged from the water heater heat exchange pipe outlet (37), and the auxiliary water heater (40) Connected to the machine water supply pipe (41). That is, the water pressure supplied from the hot water supply heat exchange pipe water supply pipe (38) becomes the water pressure of the auxiliary hot water supply water supply pipe (41) as it is, and the hot water is discharged from the hot water tap (43). Therefore, it can be said that the exhaust heat utilizing hot water storage hot water supply apparatus shown in FIG. 2 described later is an effective apparatus in a site where a hot water supply pressure is required at the hot water tap (43). Note that the water heater can body pressure safety valve (46) shown in FIGS. 1 and 2 is a safety device that must be attached to the connection can body having the pressure reducing check valve (29). The circulation pipe air vent valve (45) attached to the circulation pipe connecting the hot water storage can water heater (28) and the hood heat exchanger (2) circulates by removing the air generated in the circulation water path. It can be said that it is an important valve for preventing the idling of the pump (26) and improving the thermal efficiency. Further, the exhaust heat utilizing hot water storage hot water supply apparatus of FIG. 2 is different from the apparatus of FIG. 1 in the flow of water, but the exhaust heat has the same flow effect as shown in FIG. It is released into the atmosphere at a lower temperature.
The present invention is an exhaust heat utilizing hot water storage hot water heater having the above configuration.
