PROBLEM TO BE SOLVED: To provide an infrared heater including a discharge guide to lower a temperature in a heater body portion by guiding hot air from an air trunk of a circulator to a front part of the heater body portion by utilizing an expanded passage cross-sectional area by connecting the discharge guide to a discharge port at a downstream side of the air trunk of the circulator.SOLUTION: In an infrared heater including a heater body portion 2, a burner disposed at a rear lower portion of the heater body portion 2, a combustion chamber formed inside of the heater body portion 2, and a radiation disc disposed at a front part of the heater body portion, a circulator is disposed at a rear upper portion of the heater body portion, a suction port 14 at an upstream side of an air trunk of the circulator and a discharge port 15 at a downstream side of the air trunk are disposed at a front upper portion of the heater body portion, and a discharge guide is connected to the discharge port 15 of the air trunk of the circulator to guide the hot air from the air trunk of the circulator to a front part of the heater body portion 2 by utilizing an expanded passage cross-sectional area.SELECTED DRAWING: Figure 1 |
