PURPOSE:To make it possible to reduce the speed of air of which the temperature is raised by providing a diffuser section at a position before the discharged air from a fan for raising the temperature in the device and cooling in it goes out of the body of the device and reducing the speed of the discharged air by said diffuser section. CONSTITUTION:Air of which the temperature is raised by a lamp 12 is collected by suction force of an air fan 11, and passes through a discharged air duct 13 and is led to a diffuser 14. In the diffuser 14 the speed of the hot air which flows and comes vigorously by the action to covert the flow speed into pressure is reduced and slowly discharged from a large air discharge port which is open in all directions. Especially in the diffuser 14 depending on the position of the connection port 13a of the air discharge duct 13 the incoming air flow is straightened and made easy to flow out by a blast adjusting plate 15b at a position far from the air discharge port and the flow of the incoming air flow is obstructed by a blast to reduce the flow speed which could not be completely reduced and then the incoming air is discharged. |
