Abstract

PURPOSE:To restrain the temperature rise of a space in a main body casing outside of a duct efficiently and improve safety property as well as appearance by a method wherein venting parts, communicating with the space in the main body casing outside of the duct, are formed on the peripheral walls of a bell mouth forming body. CONSTITUTION:When a propeller fan 18B is rotated by the driving of a motor 18A, indoor air is induced into a bell mouth forming body 19 through a fan guard 27 and a suction port 3. Air from the propeller fan 18B flows toward a combustion cylinder 17 and is mixed with the exhaust gas of combustion, which is generated by combustion in a burner 7, whereby heat exchange is effected between them and warm air is produced, then, the warm air is discharged out of a warm air outlet port 2. In this case, venting ports 25, communicating with a space in a main body casing 1 outside of a duct 20, are provided on the peripheral walls 19B of a bell mouth forming body 19 and, therefore, the propeller fan 18B sucks the air in the space in the main body casing 1 outside of the duct 20 through the venting ports 25. According to this method, the flows of air are generated around a burner case 15 and the duct 20 whereby temperature rise in a space near the burner 7 and the space around the duct is restrained efficiently.
