って電子部品に異常を生じない構造となっている。Water enters from the water inlet 1a and absorbs heat in the heat exchanger 1, and hot water is supplied from the outlet 1b. The gas enters through the gas port 5a, reaches the burner 5, is mixed with air supplied by the combustion air fan 4, and is combusted in the burner 5. On the other hand, air necessary for combustion in the burner 5 is supplied from outdoors through an air supply pipe 2, an air supply passage 3, and a combustion air fan 4 to the burner 5. Further, the combustion gas from the burner 5 passes through the heat exchanger 1, passes through the exhaust passage 7, and is discharged outdoors from the exhaust pipe 6 provided inside the air supply pipe 2. The electrical component that controls the combustion air fan 4 and the like includes a printed circuit board 10 on which electrical components are mounted, an electrical component case 9 that fixes the printed circuit board and is airtightly fixed to the exterior case 9, and an electrical component that connects the electrical component case 9 and the exterior. It consists of a temporary shield 8 provided within the electrical equipment case 9 between the cases 11. Since the printed circuit board 10 on which electrical components are mounted generates heat when using a water heater, the air supply port 11a of the outer case passes through the air supply port 8a of the shielding plate 8, and then from the air supply port 8b of the shielding plate 8. Air flows through the air supply port 11b of the exterior case 11 due to natural convection. This air flow occurs even if the water heater is installed in a highly airtight indoor room and the indoor pressure becomes negative when a ventilation fan or range hood is used, so the electronic components inside the electrical case 9 are not sufficiently cooled. That will happen. In addition, indoor dust and water vapor can be removed by shielding plate 8.
(The air supply ports 11a and llb and the air supply ports 8a and 8b are shifted in position.), and the electronic components It has a structure that does not cause any abnormality.
