Description
【考案の詳細な説明】 本考案は暖房給湯機に関する。[Detailed explanation of the idea] The present invention relates to a heating water heater.
従来の給湯及び暖房を行う２回路式暖房給湯機の温度制
御は８０℃位であり、又暖房配管は比較的直径の太い管
で施工されて来た。Conventional two-circuit heating water heaters for supplying hot water and heating have a temperature control of about 80° C., and heating piping has been constructed with relatively large diameter pipes.
しかしながら、設備費等を低減する為に小口径パイプを
使い温水循環量を減らし高温水を流して暖房負荷（室内
）により温度差を大きくとる方法が採用されつつある。However, in order to reduce equipment costs, etc., a method is being adopted in which small-diameter pipes are used to reduce the amount of hot water circulated and high-temperature water is flowed to increase the temperature difference depending on the heating load (indoors).
しかしながら、このような方法では、ボイラー内の湯温
を高温制御せねばならず、又高温では給湯上限限界温度
に問題が出てくる。However, in such a method, the temperature of the hot water in the boiler must be controlled at a high temperature, and at high temperatures, a problem arises regarding the upper limit temperature for hot water supply.
更に、ボイラー缶内高温水の為に蒸気が発生しやすく気
抜きの問題、そして缶体上部にエアー留りが有れば缶体
材料の腐食問題も起る。Furthermore, the high temperature water inside the boiler can easily generates steam, causing problems with venting, and if air remains in the upper part of the can, corrosion of the can material may occur.
更に他に、本考案が対象としていをような高温制御を行
なう暖房給湯機においては（一般的な暖房給湯機にも言
えることでもあるが）、暖房及び給湯負荷は変動するも
のであり、′最大負荷に合わせた暖房及び給湯出力を持
った暖房給湯機が選択される。Furthermore, in heating water heaters that perform high temperature control such as the one targeted by the present invention (this also applies to general heating and water heaters), the heating and hot water supply loads fluctuate; A heating and water heater with a heating and hot water output that matches the maximum load is selected.
しかして、その給湯出力と給湯負荷とが完全にバランス
した状態では、缶内温度が積層状態になることはないが
、これは給湯出力と給湯負荷とが理想的な状態の時だけ
である。However, in a state where the hot water supply output and the hot water supply load are perfectly balanced, the temperature inside the can will not reach a stacked state, but this only occurs when the hot water supply output and the hot water supply load are in an ideal state.
また、暖房負荷がある場合にも、缶内の温水が循環する
ことにより同様に缶内温度の積層状態は生じないもので
ある。Further, even when there is a heating load, the hot water inside the can circulates, so that the temperature inside the can does not stack up.
しかし、暖房負荷がなく、給湯負荷のみがある場合につ
いて考えると、現実には給湯出力と給湯負荷とはバラン
スしておらず、このためより完全に近いバランスを保て
るように各種の方法で制御されているが、例えば給湯出
力が給湯負荷よりも勝っていた場合には、給湯用熱交換
器や温度制御スイッチの取付は位置によって缶体上部に
高温水が残り、積層状態となり、危険となることがある
。However, when considering the case where there is no heating load and only a hot water supply load, in reality the hot water output and the hot water supply load are not balanced, and therefore various methods are used to maintain a more perfect balance. However, if, for example, the hot water supply output exceeds the hot water supply load, depending on the position of the hot water supply heat exchanger or temperature control switch, high temperature water may remain at the top of the can, creating a dangerous situation. There is.
すなわち、缶内の温水が高温で一定の時に、給湯負荷を
かけた場合、温度制御スイッチが缶体の中間部あるいは
下部にありかつ給湯用熱交換器も缶体の中間部あるいは
下部に位置しているときには、缶体中間部以下の缶内温
水が給湯用熱交換器と大きな熱交換をしてしまうことか
ら、缶体上部の高温水は残されてしまう（この部分は高
温蓄熱部と称されている）。In other words, if hot water in the can is kept at a constant high temperature and a hot water supply load is applied, the temperature control switch is located in the middle or lower part of the can, and the hot water heat exchanger is also located in the middle or lower part of the can. When the can body is heated, the hot water inside the can below the middle part of the can undergoes a large heat exchange with the hot water heat exchanger, so the high temperature water in the upper part of the can remains (this part is called the high temperature heat storage area). ).
そして、缶体中間部以下に取付けられている温度制御ス
イッチが缶体中間部以下の缶内温水が設定値以下の温度
になったことを検出して、加熱器具が再び作動した時に
は、かかる高温蓄熱部に高温水が滞留して積層状態とな
り、やがて沸騰を起す。Then, when the temperature control switch installed below the middle part of the can body detects that the temperature of the hot water in the can below the middle part of the can body has fallen below the set value, and the heating device is activated again, the high temperature High-temperature water stays in the heat storage part, forming a layered state, and eventually boils.
また、温度制御スイッチが缶体上部にありかつ給湯用熱
交換器が缶体中間部より下に位置する場合にも、上記と
同様に、缶体上部の缶内温水が給湯用熱交換器と大きな
熱交換をするので、缶体上部に高温蓄熱部が残り、した
がって給湯負荷を満足していなくても缶体上部に取付け
られている温度制御スイッチが再加熱信号を出さなくな
っててしまうことになる。Also, if the temperature control switch is located at the top of the can body and the hot water heat exchanger is located below the middle part of the can body, the hot water inside the can at the top of the can body is connected to the hot water heat exchanger in the same way as above. Due to the large amount of heat exchange, a high-temperature heat storage area remains at the top of the can, which means that even if the hot water supply load is not met, the temperature control switch installed at the top of the can no longer issues a reheating signal. Become.
一方、温度制御スイッチが缶体中間部にありかつ給湯用
熱交換器が缶体上部に位置する場合においては、ある程
度以上の給湯負荷があるときには上述したような高温蓄
熱部は生じないが、給湯無負荷あるいは極小給湯負荷の
ときにはやはり高温蓄熱部が生じる。On the other hand, if the temperature control switch is located in the middle of the can and the hot water heat exchanger is located in the upper part of the can, the above-mentioned high-temperature heat storage area will not occur when the hot water supply load exceeds a certain level; When there is no load or a minimal hot water supply load, a high temperature heat storage section still occurs.
同様に、温度制御スイッチ及び給湯用熱交換器をともに
缶体上部に位置させても、給湯無負荷時には高温蓄熱部
が生じる。Similarly, even if the temperature control switch and the heat exchanger for hot water supply are both located at the upper part of the can body, a high-temperature heat storage portion is generated when there is no load on the hot water supply.
このような場合において、高温蓄熱部が生じるのは、缶
体の伝熱部（煙管）に蓄熱があり、この蓄熱のために缶
内水が温度制御スイッチの設定よりも高温になるからで
ある。In such cases, a high-temperature heat storage area occurs because there is heat storage in the heat transfer part (smoke pipe) of the can body, and this heat storage causes the water inside the can to reach a higher temperature than the temperature control switch setting. .
したがって、このような缶体伝熱部の蓄熱による缶内水
の温度上昇を考慮に入れると、許容限界近＜（９０〜９
３℃）での温度制御は不可能となる。Therefore, if we take into consideration the temperature rise of the water inside the can due to heat accumulation in the heat transfer part of the can, it is close to the allowable limit <(90~9
3°C), temperature control becomes impossible.
また、暖房負荷時の出口温度は、温度制御スイッチを缶
体の中間部あるいは下部に取付けた場合には、この缶体
伝熱部の蓄熱により制御温度以上になり、やはり高温制
御は難かしくなる。In addition, if the temperature control switch is installed in the middle or lower part of the can, the outlet temperature during heating load will exceed the control temperature due to heat accumulation in the heat transfer part of the can, making high temperature control difficult. .
本考案は、上記の問題に鑑みて、暖房給湯機の基本的機
能は十分満足し且つ湯温を許容限界近く（９０〜９３℃
）にまで高め、しかも缶内の温水を沸騰させることなく
良好な制御を行なわせしめる暖房給湯機を提供するもの
である。In view of the above-mentioned problems, the present invention satisfies the basic functions of a heating water heater and maintains the water temperature close to the permissible limit (90 to 93 degrees Celsius).
), and also provides a heating water heater that can perform good control without boiling the hot water in the can.
以下図面を参照して、本考案の好適な実施例について説

４は給湯用熱交換器を示し、その構造は第１図に示すよ
うにタンク型又は第２図に示すようにリイル型であって
、その下側給水人口５及び上側給湯出口６はそれぞれ温
水槽１の側壁を貫通して設けられている。Reference numeral 4 denotes a heat exchanger for hot water supply, and its structure is either a tank type as shown in Fig. 1 or a reel type as shown in Fig. 2, and its lower water supply port 5 and upper hot water supply outlet 6 are respectively heated. It is provided to penetrate the side wall of the water tank 1.
給水人口５は図示しないジスターン又は逆止減圧弁に接
続され、また給湯出口６は図示しない安全弁及び出湯栓

７は燃焼室であり、第４図に示すようなジャケットタイ
プ構造の場合もある。7 is a combustion chamber, which may have a jacket type structure as shown in FIG.
８は温水槽１内を上下に貫通して設けた煙管であって、
単管あるいは複数の管からなっている。8 is a smoke pipe provided vertically penetrating inside the hot water tank 1,
It consists of a single tube or multiple tubes.
缶体上部９は第１図又は第３図に示すような形になって
いて、この缶体上部９の一部分はエアーセパレーター１
２に大径のパイプにて接続されている。The can upper part 9 has a shape as shown in FIG. 1 or 3, and a part of the can upper part 9 is connected to the air separator 1.
It is connected to 2 by a large diameter pipe.
１０は環状隔壁であって、熱交換器４と煙管８との間に
配置され、その下端は熱交換器の給水入口５よりも下方
に延びており、またその上端は熱交換器４の給湯出口６
よりも下方に延びて缶体上部の缶壁との隙間が缶内の湯
の自然対流による循環攪拌が必要十分に行なわれる程度
にせまくなるよう缶体上部の缶壁に近接して位置する。Reference numeral 10 denotes an annular bulkhead, which is disposed between the heat exchanger 4 and the smoke pipe 8, whose lower end extends below the water supply inlet 5 of the heat exchanger, and whose upper end extends below the water supply inlet 5 of the heat exchanger 4. Exit 6
It is located close to the can wall of the upper part of the can body so that the gap between the upper part of the can body and the can wall is narrow enough to ensure necessary and sufficient circulation stirring of the hot water in the can by natural convection.
実験によれば、出力２４０００ｋｃａｌ／ ｈ程度の暖
房給湯機の場合では、この隙間は２０〜３０ｍｍ程度で
あり、これは勿論缶体形状、缶出力により異なってくる
。According to experiments, in the case of a heating water heater with an output of about 24,000 kcal/h, this gap is about 20 to 30 mm, which of course varies depending on the shape of the can and the output of the can.
環状隔壁の形状は、缶体の形状に合わせて、例えば第３
図に示すように缶体上部９の部分に漏斗形に開いて位置
しているか又は第１図に示すように缶体上部９の部分に
ストレートに位置している。The shape of the annular partition wall is determined according to the shape of the can body, for example, the shape of the third
As shown in the figure, it is located in the upper part 9 of the can body in a funnel-shaped manner, or as shown in FIG. 1, it is located straight in the upper part 9 of the can body.
１１は温度制御スイッチ保護管であって、その先端は缶
内湯の温度が最高になる位置である環状隔壁１０の上部
中央部まで突出して位置し、これによりこの保護管に収
容されている温度制御スイッチ（図示せず）の先端も環
状隔壁１０の上部中央部に位置している。Reference numeral 11 denotes a temperature control switch protection tube, the tip of which protrudes to the upper center of the annular bulkhead 10, which is the position where the temperature of the hot water in the can is at its highest. The tip of a switch (not shown) is also located at the upper center of the annular partition wall 10.
次に、缶内の湯の動きについて説明すると、燃焼室９内
に設けた図示しない燃焼器具又は加熱器具により加熱さ
れた缶内の水は高温水となって缶体上部に上昇をする。Next, to explain the movement of hot water in the can, the water in the can heated by a combustion device or heating device (not shown) provided in the combustion chamber 9 becomes high-temperature water and rises to the upper part of the can.
加熱された湯は環状隔壁１０の内側を通り缶体上部に達
する。The heated hot water passes inside the annular partition wall 10 and reaches the upper part of the can body.
ここで環状隔壁１０を境にして缶内対流を始める。At this point, convection within the can begins with the annular partition wall 10 as a boundary.
そして、環状隔壁１０の内側の温水温度が温度制御スイ
ッチの設定温度になった時点で加熱器具は停止するが、
この時の環状隔壁外側の温水温度はまだ設定温度に達し
ておらず、したがって環状隔壁１０を境にして対流が行
われ、缶体伝熱部（煙管８）が保有している熱量を吸収
して、缶内温水温度はほとんど一定となる。The heating appliance stops when the temperature of the hot water inside the annular partition wall 10 reaches the set temperature of the temperature control switch.
At this time, the temperature of the hot water outside the annular partition has not yet reached the set temperature, so convection occurs across the annular partition 10, absorbing the amount of heat held by the can body heat transfer part (fume pipe 8). Therefore, the temperature of the hot water inside the can remains almost constant.
これにより、給湯負荷をかけた場合、給湯用熱交換器４
内を流れる水は環状隔壁１０の外側の缶内温水と熱交換
をし、この熱交換した缶内温水は比重が重くなり、温水
槽１の下部に向って流れる。As a result, when a hot water supply load is applied, the hot water supply heat exchanger 4
The water flowing inside exchanges heat with the hot water inside the can outside the annular partition 10, and the hot water inside the can after this heat exchange has a higher specific gravity and flows toward the lower part of the hot water tank 1.
この温水槽下部に流れた温水はそれから隔壁１０の内側
で煙管８と熱交換をして上昇し温水槽内を循環し、これ
により高温蓄熱部は上部に残らず温水槽内の湯温を許容
限度近くまで高めても沸騰することはなく、ボイラとし
て十分な機能を満足させることができる。The hot water flowing into the lower part of the hot water tank then exchanges heat with the flue pipe 8 inside the partition wall 10, rises, and circulates inside the hot water tank, so that the high temperature heat storage part does not remain in the upper part and allows the temperature of the water in the hot water tank. Even if the temperature is raised close to the limit, boiling will not occur and the boiler can function satisfactorily.

となった。As actual data, boiler operation was started with water in the can at 25°C in an environment with an outside temperature of 23.6°C, and the temperature ranged from 39.5 to 90.5°C.
to stop the operation, and after a certain period of time, the heat exchange coil
When water is supplied at 7.6°C and hot water is tapped, if there is no annular partition, the temperature at the top of the can reaches a maximum of 104°C depending on whether the heating device is turned on or off, and the difference from the average temperature at the center of the can is about 13.
When the temperature reaches 0 to 20.0°C, the temperature control switch is set to the position where it can most sensitively detect the hot water temperature inside the can, and even if the temperature control switch cannot meet the hot water output in the heat exchanger, it sends a reheating signal. Meanwhile, boiling steam from the expansion tube of the can reached up to distanced, creating an extremely dangerous situation.

も満足した。On the other hand, an annular partition wall is provided so that its upper end is close to the can wall at the upper part of the can body, and a temperature control switch protection tube is accommodated therein with its tip protruding to the center of the upper part of the annular partition wall. In a can in which the tip of the temperature control switch is located at the center of the upper part of the annular partition, even if hot water is started under the same conditions, the temperature difference between the average temperature at the center of the can and the upper part of the can is 5.0. ℃, there was no buildup caused by repeatedly turning the heating device on and off, and the hot water supply output was satisfactory.
