ABSTRACT:
A cooling device for halogen lamps in microwave ovens is disclosed. In a microwave oven, the halogen lamp is installed on the top wall of a cavity. The lamp is operated by electric power applied thereto through a sealing part provided at each end thereof. The lamp thus radiates heating light waves, having a predetermined wavelength, into the cavity. A light reflection plate surrounds and holds the halogen lamp while forming a lamp chamber on the top wall of the cavity and allows the light waves to be guided from the lamp into the cavity, with the sealing parts of the lamp being positioned outside the light reflection plate. A cooling device generates a cooling air current and guides the cooling air current to the sealing parts positioned outside the light reflection plate.
