構を設けである湯沸器における安全対策に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a so-called open-type water heater that releases combustion exhaust indoors. This invention relates to safety measures for water heaters equipped with a reversible combustion mechanism.
近年の住宅は非常に密閉化し、捷た、そのような住宅が
空FIIiI1面等で勝れた住宅として評価されるに至

に室内の酸素濃度が低下し、不完全燃焼を生じ、遂には
不測の消火によって生ガスが放出されるおそれがある。In recent years, houses have become very airtight and have become airtight, and such houses have come to be evaluated as houses that excel in air FIIIiI level 1. If you use an open water heater continuously for a long time or if you use it repeatedly without a long period of time, the oxygen concentration in the room will gradually decrease, causing incomplete combustion, and eventually due to unexpected fire extinguishing. Raw gas may be released.

いようにする種々の技術が提案されているが、何れも天
川1面で難点がめった。As a technique to prevent incomplete combustion caused by such a decrease in oxygen concentration, the use time measuring section '1. L. When the integrated value reaches 1st shift, which is determined from the amount of oxygen consumed during combustion, the amount of carbon dioxide gas generated, the size of the room, and the natural ventilation performance of the room, combustion is automatically stopped, Various techniques have been proposed to prevent incomplete combustion, but all of them have encountered difficulties in the Amakawa area.

ようにする点にある。The present invention is such a combustion stop technology, and the object of the present invention is to calculate the total usage time of 1lJllI411t and to stop the combustion when the set settlement value is reached, whether in continuous use or repeated use. The point is to ensure that the stoppage is reliable and appropriate.

構を設けである事を特徴構成とする。In order to achieve the above object, the present invention is equipped with a water boiler and an automatic combustion stop device, and is equipped with a flow rate measuring mechanism that measures and integrates the flow rate of water supply, and the integrated value by this flow rate measuring mechanism is set. The present invention is characterized in that a mechanism is provided which automatically stops burner combustion by cutting off fuel supply to the burner when the burner reaches a certain value.
即ち、連続使用、繰返し使用のいずれの使用時(バーナ

の燃焼供給を遮断して燃焼を自動停止する点に特徴があ
る。In other words, water is naturally supplied regardless of whether it is used continuously or repeatedly (when boiling water by burning a burner), and the water supply flow rate and usage time are almost proportional. By focusing on a certain point and integrating the water supply flow rate, the usage time (burner combustion time) using water as a medium is measured, and when the needle side time reaches the set time, the combustion supply to the burner is cut off. It is unique in that it automatically stops combustion.

器の安全使用を保証でき1に至った。Therefore, in both continuous and repeated use, it is possible to reliably measure and integrate only the time during which the burner is actually burning, so the amount of oxygen consumed due to burner combustion,
Based on the amount of carbon dioxide gas generated, the size of the room, or the natural ventilation performance of the room, the flow rate (use time) for automatically stopping burner combustion is set directly to avoid the risk of incomplete combustion. By doing so, even if ventilation is not sufficient and well-performed, burner combustion will automatically stop before incomplete combustion occurs, ensuring safe use of the water heater. It reached 1.
