Micro-wave oven generally includes: the body of heater being provided with the furnace chamber for cooking food; For the fire door of selective opening and closing furnace chamber.In addition, the side of body of heater is provided with electric panel room, the various electric components comprised for generating the magnetron to furnace chamber irradiating microwaves are provided with in electric panel room, at top and the rear face of the end face and body of heater below that are equivalent to furnace chamber, be provided with the heater for generating the heater heat transmitted to furnace chamber.Usually, the heater being arranged on the upper of furnace body of the end face being equivalent to furnace chamber uses in based on the heating operation of convection current, and the heater being arranged on the rear face being equivalent to furnace chamber body of heater below uses in based on the heating operation of radiation.
Current recent design is that the top of micro-wave oven and bottom are provided with barbecue tube, the function of electric oven and the function of micro-wave oven is combined, and namely can carry out microwave cooking to food, the Multi function Barbecue can roasted food again.
Fig. 1 is the structural perspective of hot air convection structure of microwave oven in prior art.As shown in Figure 1, hot air convection structure of microwave oven comprises: be arranged on the convection fan 2 driven by fan electromotor (not shown) outside microwave cavity body wall 1, microwave cavity body wall corresponds on convection fan position cellular enter the cellular exhaust vent 3 of air holes 4 and microwave cavity body wall upper and lower.
The course of work of hot air convection structure of microwave oven is as follows:
During micro-wave oven work, fan electromotor drives convection fan 2 to rotate, by the hot blast in micro-wave oven furnace chamber from the space entered between air holes 4 suction chamber body wall and microwave oven shell, atmospheric pressure in space increases, hot blast is from the space between exhaust vent 3 exhaust chamber body wall and microwave oven shell, reenter in micro-wave oven furnace chamber, complete the process of hot air convection.
What suck due to hot air convection structure of microwave oven is containing the air of oil smoke in furnace chamber, and containing the air of oil smoke after barbecue tube heating, oil smoke decomposes and produces a lot of poisonous and hazardous gas.These poisonous and hazardous gases are led back in furnace chamber again, heat food.Like this, in micro-wave oven, contaminated air is recycled after hot air convection, can cause cyclic polluting to food, brings adverse effect to the healthy of client.
Summary of the invention
The present invention is recycled heat food in order to the air solved containing oil smoke in prior art, food is caused to the problem of cyclic polluting, and provides a kind of hot air convection structure of microwave oven being provided with the filtration oil smoke of screen pack and filter cotton.
The technical scheme that the present invention takes for the technical problem existed in solution known technology is:
Hot air convection structure of microwave oven of the present invention, comprises the convection fan be arranged on outside microwave cavity body wall, be arranged on microwave cavity body wall convection fan position cellular enter air holes and be arranged on the cellular exhaust vent of microwave cavity body wall upper and lower; Between microwave cavity body wall and convection fan, be provided with the screen pack filtering oil smoke, the periphery of screen pack is provided with the retainer ring for fixing screen pack; The surface of convection fan scribbles the automatically cleaning enamel layer that one deck absorbs oil smoke and pernicious gas; The outside of the exhaust vent of microwave cavity body wall upper and lower is provided with filters silk floss.
Described screen pack is metal filter screen.
Described filter cotton is cotton for filtering with the activated carbon filtration of clean air.
The advantage that the present invention has and good effect are:
Hot air convection structure of microwave oven of the present invention, can will roast filtering oil smoke, and the toxic and harmful after being decomposed by oil smoke filters and absorbs, and obtains clean air, for circulating-heating food.Such heating food out health and safety more, ensures that client's is healthy, also makes user obtain satisfied barbecue effect simultaneously.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in detail.Parts same as the prior art employ identical symbol.
Fig. 2 is the structural perspective of hot air convection structure of microwave oven of the present invention; Fig. 3 is the perspective view of filter fan in the present invention; Fig. 4 is the structure chart of screen pack in the present invention; Fig. 5 is the mounting structure stereogram of filter fan and screen pack in the present invention.
As shown in Figures 2 to 5, the first embodiment of hot air convection structure of microwave oven of the present invention, comprises the convection fan 7 be arranged on outside microwave cavity body wall 1; Be arranged on microwave cavity body wall convection fan 7 position cellular enter air holes 4 and be arranged on the cellular exhaust vent 3 of microwave cavity body wall upper and lower; The metal filter screen 6 of the filtration oil smoke arranged between microwave cavity body wall 1 and convection fan 7; The filtration silk floss 5 of the arranged outside of the exhaust vent of microwave cavity body wall upper and lower.
Metal filter screen filters from the hot blast entered between air holes 4 suction chamber body wall and microwave oven shell the hot blast in micro-wave oven furnace chamber.
