Oven equipped with double convection-fans

摘要

An oven with double convection fans is provided to decrease loss of suction air by mounting a convection fan and an auxiliary convection fan in a blower chamber, and to circulate air efficiently by increasing flow rate of air with the auxiliary convection fan. An oven includes a body opening forward, a heating cooking chamber formed in the body, a blower chamber formed in the heating cooking chamber, a convection heater installed in the blower chamber, and a convection fan(70) installed in the blower chamber to circulate air in the heating cooking chamber. An auxiliary convection fan(73) is installed in the middle of the convection fan to guide inflow air into the convection fan. The convection fan is composed of first blades(76) extended radially from the center, and second blades(79) bent from the first blades. The auxiliary convection fan comprises a circular plate(87), and third blades(93) formed in the surface of the circular plate to transmit air.
