PROBLEM TO BE SOLVED: To provide an air curtain with a heater in which a sub air channel is provided between an inner wall surface of a blowing air channel and the heater to reduce the frequency of the maintenance in the air channel.SOLUTION: An air curtain with a heater includes: an electric blower 4; and a heater 8. The heater 8 is provided at a blowing air channel 12, and the electric blower 4 and the heater 8 are covered by a front panel 10. A pressure of airflow flowing through a suction grille 6 provided on the front panel 10 is increased by the electric blower 4, and the airflow is heated by the heater 8 to be blown from a discharge port 9. A separation distance is established between an inner wall surface 15 of the blowing air channel 12 and the heater 8 to provide a sub air channel 19.SELECTED DRAWING: Figure 1 |
