<p>PURPOSE:To miniaturize the heater by a structure wherein a part of the air of a combustion fan is sent to a heat exchange part and an exhaust port in order to eliminate a hot air fan. CONSTITUTION:A branch discharge port 9 is provided at the fan casing 8a of the combustion fan 8 and the air sucked from a suction port 5 is sent to the heat exchange part 7 in order to be turned into hot air. A plurality of nozzles 11a and 11b are bored along the heat exchange part 7 and the exhaust port 6 on a discharge pipe 10 connected to said branch discharge port 9. Diffusers 12a and 12b are arranged at the tip of the nozzles 11a and 11b respectively. Owing to the structure as described just above, the airs jetted from the nozzles 11a and 11b are diffused and supplied to the heat exchange part 7 and the exhaust port 6. In such a manner as mentioned above, a hot air fan is eliminated and the miniaturization and energy-saving of the heater is contrived.</p> |
