Refer to Fig. 1, the micro-wave oven 100 of present pre-ferred embodiments comprises cavity 102, fan component 104 and wind scooper 106.
Cavity 102 offers the passage 108 communicated with this this inside, chamber.Please refer to the drawing 2, such as, the quantity of passage 108 is multiple, and multiple passage 108 is arranged in rectangular shape.The cylindrical hole of each passage 108 in comparatively easily processing.
Fan component 104 is arranged on this cavity 102, and this fan component 104 has air outlet 110.
Wind scooper 106 is arranged on this cavity 102 side, please refer to the drawing 4, and this wind scooper 106 comprises Venturi effect cavity 112.Incorporated by reference to Fig. 3, this Venturi effect cavity 112 comprises air inlet 114 and air outlet 116, and this air inlet 114 communicates with this air outlet 110, and this air outlet 116 communicates with this passage 108.
Particularly, the air inlet 114 of Venturi effect cavity 112 is comparatively large, and air outlet 116 is less.The air-flow that fan component 104 blows out through air outlet 110 is entered by larger air inlet 114, is blown out by less air outlet 116.
Therefore, the flow velocity of the air-flow that the velocity ratio air inlet 114 of air-flow blown out at air outlet 116 enters wants large, produces negative pressure, produce suction-operated to the air-flow near air outlet 116 near air outlet 116.
Further, the Venturi effect cavity 112 being arranged on cavity 102 side forms with cavity 102 side the ventilation duct more sealed, and further enhancing Venturi effect.
This cavity 102 is for placing by heat food.When micro-wave oven 100 works, the microwave of generation is fed in cavity 102 and heats by heat food.During heating, the pollutant such as oil smoke and/or steam may be discharged by heat food.
While micro-wave oven 100 works, on the one hand, fan component 104 can cool the electricity piece of micro-wave oven 100.On the other hand, the air-flow that the air outlet 110 of fan component 104 blows out also can enter Venturi effect cavity 112, makes the air outlet 116 of Venturi effect cavity 112 produce negative pressure, and then by the air-flow of passage 108 sucking-off cavity 102 inside.
Further, due in the process of heat food, the temperature in cavity 102 can raise, and therefore, the gas in cavity 102 can raise and expand by Yin Wendu, and then is discharged outside cavity 102 by passage 108.That is, the gas in cavity 102, because of the temperature difference inside and outside cavity 102, self also produces the trend of flowing outside cavity 102.
Therefore, the pollutant of cavity 102 inside can be discharged in time under multiple action, can not stop or the less cavity 102 that rests on inner, thus ensure that the service life of micro-wave oven 100.
