本発明は、一般家庭用台所などで使用するガス瞬間湯沸
器などの不完全燃焼防止装置に関するも２ベーノ
のである。Detailed Description of the Invention a1 Detailed Description of the Invention Field of Industrial Application The present invention relates to an incomplete combustion prevention device for gas instantaneous water heaters and the like used in general household kitchens.
従来の技術
近年、家庭用で特に台所などで使用するガス瞬間湯沸器

る器具では、熱交換器のフィンの間にごみが詰り、燃焼
排ガスが流れにくくなり不完全燃焼をするという現象も
あり、同様の事故発生原因となっている。BACKGROUND OF THE INVENTION In recent years, gas instantaneous water heaters for home use, particularly in kitchens, have built-in devices to prevent incomplete combustion. This is because in recent years, rooms have become increasingly airtight, and when combustion appliances are used for long periods of time, the oxygen concentration decreases, causing accidents such as carbon oxide poisoning. Additionally, in appliances that have been used for many years, dirt can become clogged between the fins of the heat exchanger, making it difficult for combustion exhaust gas to flow, resulting in incomplete combustion, which is a cause of similar accidents.
従って、不完全燃焼防止装置を内蔵した湯沸器を提案し
ているが、酸素濃度が下がった時（以下酸欠時という）
や、フィン詰り時に安全弁を離脱させる機構は部品精度
が要求され、マスプロする上で、非常に調整などで組立
工数がかかり、また歩留りの悪いものとなっている。Therefore, we are proposing a water heater with a built-in incomplete combustion prevention device, but when the oxygen concentration drops (hereinafter referred to as oxygen deficiency)
Also, the mechanism that releases the safety valve when the fins become clogged requires precision parts, and when mass-produced, it takes a lot of adjustment and assembly man-hours, and the yield is low.

詰り特性を第９図に示している。In FIG. 6, 1 is a heat exchanger and 2 is a burner, forming a combustion chamber. 3 is a holder that fixes the burner, and is configured so that the burner does not move. 4 is a reverse bias thermocouple, which works to cancel the electromotive force of the main thermocouple. 5 is the inner shell of the heat exchanger 1, which is rectangular and usually
It is made of thin copper plate. Because the inner shell 5 is thin and weak, it is difficult to determine the distance l from the burner 2 during the manufacturing process, as shown by the broken line. Therefore, the flow of air passing between the inner shell 5 and the burner 2 is unstable as shown by the arrow, and the electromotive force V2 of the reverse bias thermocouple varies over a very wide range. Figure 7 shows burner 2 and inner shell 5.
It shows the relationship between the distance l and the electromotive force v2 of the reverse bias thermocouple 4. The distance e between the burner 2 and the inner barrel 5 is distributed between a designed value of 11 gm and an actual measured value of 5 gm to 20 gm (plot of circles). As a result, the obtained reverse bias thermocouple electromotive force V2 varies from 5 mV to 14 mV. The oxygen deficiency characteristics in this uneven state are shown in FIG. 8, and the fin clogging characteristics are shown in FIG. 9.

。Cut off when the oxygen concentration is between 19 and 20% or cut off when the fin occlusion rate is between 5 and 20% is usually a phenomenon of premature cutting, and it is important to check the equipment.

However, there were problems such as carbon monoxide poisoning accidents and reduced usability of the equipment due to the increase in CO due to the delayed expiration. Furthermore, when heat exchangers were replaced on the market, the incomplete combustion prevention properties changed, and the specified performance could no longer be guaranteed.
