Title:
COMBUSTION EQUIPMENT
Document Type and Number:
Japanese Patent JP3845026
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To highly maintain the air blowing performance of fans without frequently doing maintenance.
SOLUTION: A hot water supply heater 1 suspended from a ceiling B of a building is provided with an exhaust tube 36 and an air supply tube 37 provided in parallel with the exhaust tube 36 to surround the exhaust tube 36, and a rain cover 10 extended from a front surface of the equipment to a front surface of fans 35a and 65a to prevent adhesion of rain drops to a controller 9. With this structure formed with the rain cover 10, an air supply passage 11 formed of a space between a cover body 4 and the rain cover 10 is formed long, and the intake resistance is increased, but a turvo fan, of which air quantity change due to a fluctuation of the wind pressure is small and which is hard to be clogged with dust, is used for the fans 35a and 65a for feeding the combustion air to a heater burner 61 to reduce the required number of maintenance and to highly maintain the air blowing performance of the fans 35a and 65a.
