ん機等の各種流体加熱装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention heats a stored fluid by heat exchange with combustion gas from a burner in an upper and lower intermediate portion inside an upper open type storage tank for storing a fluid for heating food. A heating section is provided to improve the thermal efficiency by the configuration, and a cold zone is formed in the lower part of the storage tank to prevent food residue in the stored fluid from adhering to the food to be heated. The present invention relates to various fluid heating devices such as a fryer and a boiled noodle machine that are avoided by depositing them in a zone.
〔従来の技術〕 従来、上記流体加熱装置において加熱部を構成するに、
第８図及び第９図に示すように、貯槽（１）の上下中間
部に複数の貫通管（11）を並設し、それら貫通管（11）
にバーナ（４）からの燃焼ガスを流動させることにより
貯留流体を加熱するように構成していた。[Prior Art] Conventionally, in the heating unit in the fluid heating device,
As shown in FIG. 8 and FIG. 9, a plurality of through pipes (11) are arranged in parallel in the upper and lower intermediate portions of the storage tank (1), and these through pipes (11)
The stored fluid is heated by flowing the combustion gas from the burner (4).
図中（12）は熱効率の向上を図るために貫通管（11）内
に挿入した螺旋状蓄熱体であり、又、（６）は排気筒で
ある。In the figure, (12) is a spiral heat storage body inserted in the through pipe (11) to improve thermal efficiency, and (6) is an exhaust stack.
しかしながら、上述貫通管型式のものにあつては次の如
き問題があつた。However, the above-mentioned through pipe type has the following problems.
（ｉ） 貫通管（11）どうしの間の隙間寸法が小さいた
めに、作業終了後、貯留流体を抜きとつて貯槽（１）内
を掃除するに際して貫通管（11）よりも下方側に手を入
れることができず、貯槽（１）底部の掃除が不可能であ
つた。(I) Since the size of the gap between the through pipes (11) is small, when cleaning the inside of the storage tank (1) by draining the stored fluid after the work is completed, place a hand below the through pipe (11). It was not possible to put it in and it was impossible to clean the bottom of the storage tank (1).
（ii） 貫通管（11）よりも下方に形成されるコールド
ゾーン（Ｂ）の容積が大きいために、多量の貯留流体を
要する。(Ii) Since the volume of the cold zone (B) formed below the through pipe (11) is large, a large amount of stored fluid is required.
（iii） 貯槽（１）と複数貫通管（11）との溶接部が
多いために、燃焼炎が溶接部に接触することに起因した
使用中の槽ワレを生じることが多い。(Iii) Since there are many welded portions between the storage tank (1) and the plurality of penetrating pipes (11), in-use tank cracking often occurs due to contact of the combustion flame with the welded portions.
（iv） 燃焼炎が螺旋状蓄熱体（12）に当たることに起
因した燃焼不良を回避するために、排気筒（６）の流路
断面積を拡大して燃焼用空気の流入量を多量化している

ている状態において、自然対流による空気ドラフトが生
じ易く、そのことに起因して貯留流体が冷え易いために
温度調節状態におけるエネルギー消費量が大となる。(Iv) In order to avoid combustion failure caused by the combustion flame hitting the spiral heat storage body (12), the flow passage cross-sectional area of the exhaust stack (6) is expanded to increase the inflow amount of combustion air. However, when the stored fluid temperature reaches the set temperature, air draft due to natural convection easily occurs in the state where the burner (4) is set to a small fire state to control the temperature. Since the stored fluid easily cools, the energy consumption in the temperature control state becomes large.
本発明の目的は、加熱部構成に対する合理的、かつ、簡
単な改良で上述問題を解消すると共に熱効率を更に向上

あり、その作用・効果は次の通りである。A characteristic configuration of the fluid heating device according to the present invention is that a bottom wall of the storage tank is formed in a shape in which a central portion of the storage tank is bulged upward to form a heating portion disposed in an upper and lower intermediate portion inside the storage tank. A combustion gas guiding tubular member is formed in the space outside the storage tank formed by the wall, with its upper end opening located near the lower surface of the bottom wall, and with the side wall portion of the bulging bottom wall. A bottom plate that is provided in a state in which a gap is formed between the side wall portion and the tubular member, and that closes the space; The part is positioned below the lower end of the side wall part so as to form a combustion exhaust gas passage below the lower end of the part, and the remaining part is connected above the lower end of the side wall part. It is provided in the state, its action and effect It is as follows.
つまり、第１図及び第２図に示すように、バーナー

路（７）に流入する。That is, as shown in FIG. 1 and FIG. 2, the combustion gas from the burner (4) is guided by the tubular member (3) and flows upward, and the upper end side of the tubular member (3). The liquid is discharged from the opening, then hits the upper wall portion (2A) of the bulging bottom wall (2) and turns downward, and the side wall portion (2B) of the bulging bottom wall and the tubular member ( 3) downwardly flowing, then hits the bottom plate (5), flows toward the combustion exhaust gas (7), and flows into the combustion exhaust gas passage (7).
そして、燃焼ガスが上述の如く流動することにより、燃

及び側壁部分（2B）と接触して、燃焼ガスが接触する面
積が広くなり、貯留流体を効率良く加熱することができ

（ｉ） 従来構成の如き小並設ピツチの貫通管が無いの
で、掃除に際して手が貯槽内の隅々まで入り、掃除が極
めて容易となつた。(I) Since there is no through tube for small side-by-side pitches as in the conventional configuration, the hands were put into every corner of the storage tank during cleaning, and cleaning was extremely easy.
（ii） 従来構成のものに比してコードゾーンの容積が
小さいため、使用に際しての貯留流体量を従前に比して
例えば2/3程度にまで低量化できた。(Ii) Since the volume of the cord zone is smaller than that of the conventional configuration, the amount of stored fluid during use can be reduced to about 2/3, for example, compared with the conventional one.
（iii） 従来構成のものに比して溶接箇所が少ないこ
とから、使用中における槽ワレの危険性を低減できて安
全性及び耐久性を向上できた。(Iii) Since the number of welded points is smaller than that of the conventional structure, the risk of tank cracking during use can be reduced and safety and durability can be improved.
（iv） バーナ燃焼の支障となる螺旋状蓄熱体が無く、
又、バーナの燃焼室高さも充分に確保できることから、
極めて良好な燃焼を行なわせることができ、そのことに
よつて吸入空気量を従前に比して例えば30％〜40％程度
低減できて熱効率を一層向上できた。(Iv) There is no spiral heat storage that hinders burner combustion,
Moreover, since the combustion chamber height of the burner can be sufficiently secured,
It was possible to perform extremely good combustion, which made it possible to reduce the amount of intake air by, for example, approximately 30% to 40%, and to further improve thermal efficiency.
（ｖ） しかも、バーナからの燃焼ガスが、筒状部材か

から、温度調節のためにバーナを小火状態としても自然
対流によるドラフトが少なく、そのことによつて、温度
調節時における消費エネルギーを従前に比して例えば2/
3程度に低減できた。(V) Moreover, since the combustion gas from the burner flows downward toward the combustion exhaust gas passage after being discharged from the tubular member, a draft due to natural convection is generated even if the burner is set to a small fire state for temperature control. Therefore, the energy consumption during temperature control is, for example, 2 /
It could be reduced to about 3.
（vi） 燃焼室を被加熱物たる流体で囲つているため、
本体の形状が箱型の簡易な構造となり、又、燃焼室に対
する断熱対策も不要となり、さらには、本体周辺の他物
に対する熱的影響も燃焼室が本体外面に臨まないための
効果的に軽減されるというメリツトもある。(Vi) Since the combustion chamber is surrounded by the fluid to be heated,
The main body has a simple box-shaped structure, and there is no need for heat insulation measures for the combustion chamber. Furthermore, thermal effects on other objects around the main body are effectively reduced because the combustion chamber does not face the outer surface of the main body. There is a merit that it will be done.
（vii） 構造が簡単であることから製作コストが従前
に比して例えば3/4程度に低減できる。(Vii) Since the structure is simple, the manufacturing cost can be reduced to about 3/4, for example, as compared with the conventional method.
以上要するに、構造の簡略化を図りながらも、加熱性能
面、経済面、安全面、並びに、メンテナンス面のいずれ
にも優れた流体加熱装置を提供し得るに至つた。In short, it has been possible to provide a fluid heating device which is excellent in all of heating performance, economics, safety, and maintenance while simplifying the structure.
