ABSTRACT:
A blender includes a base frame, a cover for covering the base frame, a muffler housing, a motor, and a fan. The base frame includes a hollow column having a compartment for receiving the motor. Two separating plates extend downward from a bottom end of the base frame. The motor includes a lower drive shaft for driving the fan for driving ambient cool air into the compartment of the hollow column via the apertures, thereby directly cooling the motor. The separating plates prevent the hot air exiting the blender from entering the blender again.
