Embodiment Construction

[0012] As shown in Fig. 2, an exhaust motor unit 12 is arranged on the rear side of the top surface 10 of the microwave oven heating chamber with the function of extracting oil fume, which is a component for exhausting the smoke generated by the heater arranged in the microwave oven. When the exhaust motor unit 12 was working, air flowed in from both sides thereof, and the exhaust was carried out along the rear or top of the microwave oven. A fan casing 14 is also provided on the top surface 10 of the heating chamber. When observing from the inside of the heating chamber, it can be seen that the fan casing 14 protrudes toward the upper side of the heating chamber, and the stirring fan 16 can rotate inside it. The side of the fan case 14 has a plurality of suction holes 14a and exhaust holes 14b. The magnetron 22 disposed on the right side of the top surface 10 of the heating chamber can generate microwaves supplied to the inside of the heating chamber. The high-voltage trans...

Abstract

The present invention discloses an agitating fan driving device for the microwave oven with oil fume pumping function, comprising air exhausting motor set arranged at the rear end of the heating chamber top surface for forming the rearward direction gas flow, and fan case arranging gas inlet hole for sucking the air flow and air exit hole for venting inner air projecting on the top surface of the heating chamber. The present invention provides an agitating fan driving device for the microwave oven with oil fume pumping function without other driving motor to be arranged, thus the number of the components can be reduced.

Description

technical field [0001] The invention relates to a stirring fan driving device of a microwave oven with a fume extraction function, in particular to a stirring fan driving device of a microwave oven with a fume extraction function which utilizes the airflow generated by an exhaust motor unit to drive the stirring fan. Background technique [0002] The ventilation hood of the microwave oven is usually arranged on the upper side of the heater, which has the function of exhausting the smoke or hot gas generated on the heater. To heat food evenly in a microwave oven, it is necessary to inject microwaves evenly. Usually adopt the method that utilizes microwave to heat the food that rotates and the stirring fan that is arranged on the inner top surface of rotating heating chamber in the state that food is fixed to make microwave form scattering so that microwave is evenly provided to the heating method of food. Fig. 1 is a structural schematic diagram of a driving device for a sti...
