Further, the exhaust gas is supplied to the combustion machine inside the inner case 7, and the exhaust gas after combustion is released to the outside air through the exhaust gas 11115. Here, rainwater is prevented from entering the air supply port 3 completely, and the exhaust pipe 5 is prevented from entering by a top portion 6.
発明が解決しようとする課題
このような従来の地下設置用の給排気装置では、蓋２に
よる雨水の跳ね返りや、有風時のあらゆる方向からの雨
滴の吹き付けによる給気口３からの侵入までは避けられ
ず、雨水の侵入が発生する。Problems to be Solved by the Invention In such a conventional air supply/exhaust system for underground installation, it is difficult to prevent rainwater from bouncing off the lid 2 or from entering through the air supply port 3 due to raindrops sprayed from all directions during windy conditions. Inevitably, rainwater intrusion will occur.

Air within the outer case then flows into the inner case through the air vent. The air supplied to the main body housed in the inner case passes through the main body, becomes exhausted, and is discharged into the atmosphere through the exhaust pipe. If rainwater passes through the supply cylinder and enters the outer case, it will first hit the inner case and fall onto the outer bottom surface. is guided downward and accumulates in the depression. Therefore, the entire surface of the outer bottom will always be wet, and as the temperature inside the outer case increases, it will not evaporate and cause an abnormal increase in humidity. i=
You will be led to the + section. Furthermore, since the feed cylinder is connected to the outer case that substantially faces the recess, water that enters from the feed cylinder does not wet the inside of the outer case and is quickly collected in the recess.

る。Air in the atmosphere is sucked through the air supply port 34 and guided into the outer case 8 installed underground through the air supply passage 29 in the supply cylinder 30. Next, the air passes through the air port 20 and enters the inner case 11. and is supplied to the fan 9. On the other hand, fuel is supplied from the fuel pipe 16, adjusted to a fuel flow rate corresponding to the hot water supply load, and then supplied to the burner 12 together with air. The supplied fuel and air are combusted in a combustion chamber 13 by a burner 12 and become high-temperature combustion gas, which heats water in a heat exchanger 14. The low-temperature exhaust gas that has undergone heat exchange is collected in the exhaust hood 15 and guided to the ground through the exhaust passage 27 in the exhaust stack 28. The flow direction of the exhaust gas guided to the end of the exhaust passage 27 is deflected by the umbrella-shaped upper cover 32, and is discharged from the outer periphery of the upper cover 32 through the blow-off passage 33 into the atmosphere.

時における水抜き作業の場合にも活用される。Now, if water enters from the feed cylinder for some reason, the water will fall onto the inner case 11. Most of the falling water hits the slope 31 and flows directly on the slope 31, leading to the depression 26. The partially scattered water falls onto the outer bottom surface 23, flows on the inclined outer bottom surface 23, and similarly flows into the recessed portion 2.
6. Furthermore, if a large amount of water enters, some of the water may enter into the inner case 11 through the air port 20. In this case, water flows from the main body 10 to the inner bottom surface 21.
The water falls from the drain port 22 onto the outer bottom surface 23 and is similarly guided to the recess 26. The water thus accumulated in the depression 26 permeates into the ground and is discharged from the drainage section 25 having a backflow prevention function. The drainage section 25 is also used for draining water when installing the main body.
