PROBLEM TO BE SOLVED: To allow high power heating to operate immediately at the start of using by providing at least two or above heaters capable of switching to conduct the heaters, and arranging the heaters in a main passage so that the heaters and a blower lie in a straight line with respect to an air outlet. SOLUTION: An electric warm air heater body 1 has a main passage 4 for communicating a suction port 2 with an air outlet 3, a blower 5 provided in the passage 4 to supply the air toward the outlet 3, and heaters 8 for heating the air in the passage 4. As the heaters 8, at least two heaters 8 or more are provided, and the heaters 8 can be switched. The heaters 8 and the blower 5 are arranged in the passage 4 so as to lie in a straight line with respect to the outlet 3. Thus, warm air is linearly in straight line output so that its air passage resistance is small. Even if there is not preparation for thermal storage in advance, a high output of a required amount can be obtained when necessary, and high power heating can be conducted immediately at the start of use. |
