As exemplified, a portable air blowing appliance includes a housing retaining an airflow-producing electric motor-driven blower. The blower is adapted when energized for operation in either a first or a different mode. An electric heating element is adapted when energized to expel heat. An electric switch enables energizing of the blower and the heating element to either cause operation of the blower in the first mode or to cause, simultaneously, operation of the blower in the different mode and heat expulsion by the heating element. The blower is adapted for higher airflow-producing efficacy during the first mode. The heating element is disposed to warm airflow from the blower during the different mode. |
