本発明は、ガス燃焼や電気発熱によって温水を得る瞬間
湯沸器に関するものである。DETAILED DESCRIPTION OF THE INVENTION Industrial Application Minute Hand The present invention relates to an instantaneous water heater that obtains hot water by gas combustion or electric heating.
従来例の構成とその問題点
従来の例えば、ガス瞬間湯沸器の概略図を第１図に示す
。Structure of a conventional example and its problems A schematic diagram of a conventional gas instantaneous water heater, for example, is shown in FIG.
水は水入口１より水圧調整器２を通り、熱交換器３で熱
を吸収し給湯口４より供給される。Water passes through a water pressure regulator 2 from a water inlet 1, absorbs heat in a heat exchanger 3, and is supplied from a hot water supply port 4.
ガスはガス人口５よりガス圧調整器６へ流れバーナ７で
燃焼する。The gas flows from the gas port 5 to the gas pressure regulator 6 and is burned in the burner 7.
燃焼によって生じた排ガスは排気ファン８によって排気
筒９へ導かれ器外へ排出される。Exhaust gas generated by combustion is guided to an exhaust pipe 9 by an exhaust fan 8 and discharged outside the device.
寸だ排気ファン８には回転数検出部１０が装着されてお
り、常に排気ファン８の回転を検出し異常時には、燃焼
を停止させる。A rotation speed detecting section 10 is attached to the exhaust fan 8, which constantly detects the rotation of the exhaust fan 8 and stops combustion when an abnormality occurs.
排気ファンにより強制的に排気ガスを排出する燃焼器は
従来の自然ドフフトによる燃焼器に比べて側風時の安全
性に富みまた燃焼時の安全性も非常に高い。A combustor that forcibly discharges exhaust gas using an exhaust fan is safer when facing side winds and is also much safer during combustion than a conventional combustor using a natural draft.
しかし第１図に示すような強制排気式ガス瞬間湯沸器に
おいて排気筒９が何らかの物でその排気断面の一部を閉
塞されたり、長時間にわたゆある報度の風Ｆ「がかかっ
た場合、排気ファンの排気能力が落ち十分な排気が行え
ず不完全燃焼となる。However, in the forced exhaust type gas instantaneous water heater shown in Figure 1, if the exhaust pipe 9 is partially blocked by something, or if a certain type of wind F is applied for a long period of time. In this case, the exhaust capacity of the exhaust fan decreases and sufficient exhaust cannot be achieved, resulting in incomplete combustion.
第２図に、排気筒先端部に圧力を加えた場合の圧力とＣ
Ｏ／ＣＯ２の関係を示すデータの一例を示す。Figure 2 shows the pressure and C when pressure is applied to the tip of the exhaust pipe.
An example of data showing the relationship between O/CO2 is shown.
第２図より、排気筒先端部圧力が約１３ｍｍＨ２０で燃
焼性を表わすバロメーターＣｏ、／ＣＯ２の値がＩＮＳ
基準の０．０２程度となることがわがる。From Figure 2, when the pressure at the tip of the exhaust stack is approximately 13 mmH20, the value of the barometer Co, /CO2, which indicates combustibility, is INS.
It can be seen that the standard value is about 0.02.
従って強制的にファンにより排気ガスを排出する燃焼器
においても、排気筒が何らかの物でその排気断面の一部
を閉塞されたり、長時間にわたっである程度の風圧がか
かった場合、排気ファンの排気能力が落ち不完全燃焼が
生じる１つ発明の目的
本発明は上記従来の欠点を解消するもので、排気能力が
何らかの原因で低下した場合、不完全燃焼が生じる前に
燃焼を停止させる機能を持つ安全性の高い瞬間湯沸器を
目的とする。Therefore, even in a combustor that forcibly exhausts exhaust gas with a fan, if the exhaust pipe is partially blocked by something or a certain amount of wind pressure is applied for a long time, the exhaust fan's exhaust gas Purpose of the Invention The present invention solves the above-mentioned conventional drawbacks, and has a function to stop combustion before incomplete combustion occurs when the exhaust capacity decreases for some reason. The aim is to create a highly safe instantaneous water heater.

燃焼を防止し、安全性を高めるという効果を有する。Number of channels of the invention In order to achieve the above object, the instantaneous water heater of the present invention includes an exhaust fan downstream of the heat exchanger, a pressure sensor downstream of the exhaust fan, and a pressure sensor installed downstream of the exhaust fan to detect the pressure. In this case, the number of grooves is such that the function of the heat generating section is stopped, which has the effect of preventing incomplete combustion and increasing safety.

に燃焼性を示すパラメータＣＯ／Ｃ○２が０．０２以下
で燃焼が止まり不完全燃焼を防止することができる。In FIG. 3, a fan 12 is provided downstream of the heat exchanger 11, and a pressure sensor 14 is provided between the fan 12 and the exhaust pipe 13. This pressure saw sensor stops the combustion part function when the pressure exceeds a certain level. In this example, if the set pressure is 10 mm H20, combustion will stop when the parameter CO/C2, which indicates combustibility, is 0.02 or less, as can be seen from FIG. 2, and incomplete combustion can be prevented.
