Abstract

PROBLEM TO BE SOLVED: To solve the problems about a small size gas water heater in which CO is generated by the occurrence of incomplete combustion due to the influence of wind, and in which the small size gas water heater is locked and becomes unable to use when automatic fire extinguishment is repeated by an incomplete combustion prevention function due to the influence of wind.SOLUTION: Five surfaces of a small size gas water heater, which are an upper surface, left and right side surfaces, a back surface and a lower surface, are surrounded by a windbreak plate and fixed with metal fittings, screws and the like so that wind does not pass through. The windbreak plate is larger than the depth of the small size gas water heater, and when it is installed, it protrudes to the front from the front surface of the small size gas water heater by several centimeters. When the wind hardly hits the small size gas water heater, the wind becomes substantially only front wind, a wind pressure of every portion of the small size gas water heater becomes uniform, so that incomplete combustion due to the influence of wind can be prevented. However, an incomplete combustion prevention function by clogging of a burner and a heat exchanger of the small size gas water heater works irrespective of installation of the windbreak plate, and only the incomplete combustion due to the influence of wind is prevented.SELECTED DRAWING: Figure 1

Description

本発明はおもに家庭用に使用する小型ガス湯沸器について、戸や窓からの風、および、エアコンや扇風機等の風により、小型ガス湯沸器の燃焼排気が停滞して流れ出なくなったり、ガスと空気の混合バランスが崩れたりすることによっておこる、風の影響による小型ガス湯沸器の不完全燃焼を防止する防風板である。 The present invention mainly relates to small gas water heaters for home use, and the combustion exhaust of the small gas water heaters stagnate due to the wind from doors and windows and the air from air conditioners and fans, etc. It is a windbreak plate that prevents incomplete combustion of a small gas water heater due to the influence of wind, which occurs when the mixing balance of air and air is lost.

防風板として小型ガス湯沸器側面の給気口に部分的に取り付けるものはあるが、防風板が小さいため、防風板の外側から斜めに風が抜け役目を果たしていない。上面、下面に防熱板として取り付けるものもあるがこれを防風板として代用しても横からや斜め前面や背面の風に対応できない。 There is a windshield that is partially attached to the air inlet on the side of the small gas water heater. However, since the windshield is small, the wind does not escape from the outside of the windshield. Some of them are attached to the upper and lower surfaces as heat insulation plates, but even if they are used as wind insulation plates, they cannot handle the wind from the side or from the front or back.

小型ガス湯沸器について、風の影響による不完全燃焼を防止し、不完全燃焼の発生頻度を下げることで安全性向上を図るとともに、最近の小型ガス湯沸器は安全性が高く、不完全燃焼防止機能による自動消火を数回繰り返すとロックが掛り小型ガス湯沸器のメーカー担当者がロックを解除するまでの間小型ガス湯沸器が使用できない。風の影響による不完全燃焼を防止し、風による影響でロックが掛ることを防止する。ただし、小型ガス湯沸器のバーナーや熱交換器の詰りによる不完全燃焼防止機能は、防風板の取り付けに関係なく働き、風の影響による不完全燃焼のみを防止するものである。 As for small gas water heaters, incomplete combustion due to the influence of wind is prevented and safety is improved by reducing the frequency of incomplete combustion. Recent small gas water heaters are highly safe and incomplete. If automatic fire extinguishing by the combustion prevention function is repeated several times, the lock is applied and the small gas water heater cannot be used until the person in charge of the manufacturer of the small gas water heater releases the lock. Prevents incomplete combustion due to the influence of wind and locks due to the influence of wind. However, the incomplete combustion prevention function due to clogging of the burner or heat exchanger of the small gas water heater works regardless of the installation of the windbreak plate, and only prevents incomplete combustion due to the influence of wind.

小型ガス湯沸器の上面、左右側面、背面、下面の５面を風が通り抜けないように囲うことで、ほぼ正面だけの風になり、小型ガス湯沸器のどの部分も風圧が同等であり、斜めに風が吹いても上面、左右側面、背面、下面の５面による囲いで風圧が同等である。空気とガスの混合バランスも正常になり、排気がバーナー上部から上昇し小型ガス湯沸器の外へ正常に排出でき、風の影響での不完全燃焼を防止することができる。ただし、火災や給排気の安全上定めてある小型ガス湯沸器の可燃物からの離隔距離以上離し防風板を取り付けることと取り付けについて金具やねじ等で止め、防風板が外れて小型ガス湯沸器の上に落ち、排気ができないような状態にならないようにすることや、防風板が変形しにくい強度や材質であることが重要である。また、下面については下から上に向いて吹く風の防風板のため、小型ガス湯沸器の排気が抜けやすくなる風向きであり、水道配管とガス配管も通っており設置がしにくいこともあり、強風でない場所では効果にあまり差がないため上面、背面、左右側面の４面とし下面は省略可能である。 By enclosing the top, left, right, back, and bottom surfaces of the small gas water heater so that the wind does not pass through it, the wind is almost front-facing, and all parts of the small gas water heater have the same wind pressure. Even if the wind blows obliquely, the wind pressure is the same in the enclosure of the five surfaces of the upper surface, the left and right side surfaces, the back surface, and the lower surface. The mixing balance of air and gas is also normal, the exhaust gas rises from the upper part of the burner and can be discharged normally out of the small gas water heater, and incomplete combustion due to the influence of wind can be prevented. However, install a windbreak plate that is more than the separation distance from the combustible material of the small gas water heater specified for fire and supply / exhaust safety and stop it with metal fittings or screws. It is important that the windproof plate does not fall into a state where it cannot be exhausted, and that the windbreak plate is not easily deformed. In addition, the bottom surface is a windproof plate that blows from the bottom to the top, so the exhaust of the small gas water heater is easy to escape, and water pipes and gas pipes are also passed through, so it may be difficult to install Since there is not much difference in the effect in a place where there is no strong wind, the bottom surface can be omitted with four surfaces, the top surface, the back surface, and the left and right side surfaces.

小型ガス湯沸器について、風の影響による不完全燃焼を防止し、この原因によるＣＯの発生を防止でき、ＣＯ中毒発生の一因を防止できる。また、風による影響でロックが掛ることを防止し小型ガス湯沸器が稼働できる状態を多くする。 About a small gas water heater, the incomplete combustion by the influence of a wind can be prevented, generation | occurrence | production of CO by this cause can be prevented, and the cause of CO poisoning generation | occurrence | production can be prevented. In addition, the state where the small gas water heater can be operated by preventing the lock due to the influence of wind is increased.

小型ガス湯沸器の上面、左右側面、背面、下面の５面を風が通り抜けないように防風板で囲い金具やねじ等で固定する。防風板により戸や窓からの風およびエアコンや扇風機からの風が直接小型ガス湯沸器に当たらないようにする。ただし、火災や給排気の安全上定めてある小型ガス湯沸器の可燃物からの離隔距離以上離し防熱板を取り付けることが重要である。 A small gas water heater is fixed with a windproof plate, metal fittings, screws, etc. so that the wind does not pass through the top, left, right, back, and bottom surfaces. The windshield prevents wind from doors and windows and air from air conditioners and fans from directly hitting small gas water heaters. However, it is important to install a heat insulating plate that is at least a distance away from the combustible material of a small gas water heater that is defined for safety of fire and supply / exhaust.

図１の如く、小型ガス湯沸器の上面、左右側面、背面、下面の５面を風が通り抜けないように防風板で囲い金具やねじ等で固定する。防風板は小型ガス湯沸器の奥ゆきより大きく、設置すると小型ガス湯沸器の前面より手前に数ｃｍ出っ張るようにし、風が小型ガス湯沸器に当たりにくいようにする。 As shown in FIG. 1, a small gas water heater is fixed with a windproof plate, metal fittings, screws, or the like so that the wind does not pass through the top, left, right, back, and bottom surfaces. The windbreak plate is larger than the depth of the small gas water heater, and when installed, it should protrude several centimeters from the front of the small gas water heater so that the wind does not easily hit the small gas water heater.

防風板設置により
１小型ガス湯沸器を使用中に風の影響による不完全燃焼を防止し、不完全燃焼発生頻度を下げることでＣＯ中毒の危険性が減少する。
２不完全燃焼防止機能によるロックで小型ガス湯沸器の使用できない期間が、防風板設置により減少する。
の効果があり産業上の利用可能性は十分ある。 The installation of windbreak plates prevents incomplete combustion under the influence of wind while using a small gas water heater, and reduces the risk of CO poisoning by reducing the frequency of incomplete combustion.
2 The period during which the small gas water heater cannot be used due to the lock due to the incomplete combustion prevention function is reduced by the installation of the windbreak plate.
The industrial applicability is sufficient.
