ABSTRACT:
A convection oven includes an oven body having a heating chamber heated by a heat source, and a vibration unit mounted at one side of the oven body and vibrating heated air so as to be uniformly distributed within the heating chamber. As the vibration unit vibrates, air within the heating chamber can be fluctuated periodically to promote mixing between more heated air and less heated air to make temperature of air uniform. Accordingly, heat can be uniformly distributed to a cooking target or material, quality of cooking can be improved, and in addition, because cooking time can be shortened, the performance of the oven can be enhanced.
