ABSTRACT:
A cooling device for microwave ovens with halogen lamps is disclosed. The cooling device is designed to divide the cooling air current, generated from a cooling fan unit, into two currents, an upper current and a lower current. The upper and lower currents are respectively fed to the passages above and below the top wall of a cavity. The cooling device comprises a halogen lamp installed on the top wall of the cavity and radiates heating light into the cavity. A lamp protection filter is provided on the top wall of the cavity and allows the heating light to be led from the halogen lamp into the cavity. A cooling fan unit generates the cooling air current, which is guided to the passages above and below the top wall of the cavity.
