HALOGEN LAMP COOLING STRUCTURE

摘要

PURPOSE: A structure is provided to cool the sealing part of a halogen lamp which is installed in a microwave oven and is operated as an additional heating resource. CONSTITUTION: The structure is for cooling the sealing part having the highest temperature by placing the sealing part(30a) of a halogen lamp on the outer side of a reflective plate(32). The cooling apparatus comprises:a radiative lamp(30) to radiate lights by the power supply fed via the sealing part of both ends; a reflective plate(32) to cover the radiative lamp in a state of placing the both sealing parts of the radiative parts on the outer side; and a cooling air flow generation piece to generate a cooling air flow which towards the sealing part exposed out of the reflective plate.
