Description
Technical field
The present invention relates to micro-wave oven, be specifically related to a kind of micro-wave oven hot air convection structure that can filter oil smoke that is provided with screen pack and filter cotton.
Background technology
Generally, micro-wave oven is according to generating microwave by magnetron behind the power turn-on, and the cooker of food being cooked with heating objects such as these microwave irradiation foods.Such micro-wave oven can be divided into home-use micro-wave oven that is equipped with small-sized magnetron and the commerce micro-wave oven that is equipped with large-scale or a plurality of magnetrons.Micro-wave oven can also be distinguished according to the mode of heat food, and home-use micro-wave oven generally adopts the glass plate mode of rotation food, the commercial stirring fan mode that mainly adopts dispersion microwave with micro-wave oven.Commercial be mainly used in the food supply retail shop of high convenience store of frequency of utilization or short time cooking food, generally need high relatively output compared with home-use micro-wave oven with micro-wave oven.
Micro-wave oven generally includes: the body of heater that is provided with the furnace chamber that is used for cooking food; Be used for the fire door that selectivity opens and closes furnace chamber.In addition, side at body of heater is provided with electric panel room, be provided with in the electric panel room and comprise the various electric components that are used to generate to the magnetron of furnace chamber irradiating microwaves, at the top and the rear face of the body of heater of end face that is equivalent to furnace chamber and back, be provided with the heater that is used to generate the heater heat of transmitting to furnace chamber.Usually, the heater that is arranged on the upper of furnace body of the end face that is equivalent to furnace chamber is to use in the heating operation based on convection current, and the heater that is arranged on the rear face of the body of heater that is equivalent to the furnace chamber back is to use in the heating operation based on radiation.
Present recent design is to be provided with barbecue tube at the top of micro-wave oven and bottom, and the function of electric oven and the function of micro-wave oven are combined, and promptly can carry out microwave cooking to food, again the multifunctional barbecue micro-wave oven that can roast food.
Fig. 1 is the structural perspective of micro-wave oven hot air convection structure in the prior art.As shown in Figure 1, micro-wave oven hot air convection structure comprises: be arranged on the convection fan 2 that microwave cavity body wall 1 outside is driven by fan electromotor (not shown), on the microwave cavity body wall corresponding to the cellular exhaust vent 3 of the locational cellular inlet air of convection fan hole 4 and microwave cavity body wall upper and lower.
The course of work of micro-wave oven hot air convection structure is as follows:
During micro-wave oven work, fan electromotor drives convection fan 2 and rotates, with the hot blast in the micro-wave oven furnace chamber from the space between inlet air hole 4 suction chamber body walls and the microwave oven shell, atmospheric pressure in the space increases, hot blast is from the space between exhaust vent 3 exhaust chamber body walls and the microwave oven shell, reenter in the micro-wave oven furnace chamber, finish the process of hot air convection.
Because what micro-wave oven hot air convection structure sucked is the air that contains oil smoke in the furnace chamber, the air that contains oil smoke is after the barbecue tube heating, and oil smoke decomposes a lot of poisonous and hazardous gases of generation.These poisonous and hazardous gases are led again to melt down in the chamber, and food is heated.Like this, contaminated air is repeated to utilize behind hot air convection in the micro-wave oven, can cause cyclic polluting to food, gives client's the healthy adverse effect of bringing.
Summary of the invention
The present invention is repeated to utilize heat food in order to solve the air that contains oil smoke in the prior art, food is caused the problem of cyclic polluting, and a kind of micro-wave oven hot air convection structure that is provided with the filtration oil smoke of screen pack and filter cotton is provided.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
Micro-wave oven hot air convection structure of the present invention comprises the convection fan that is arranged on the microwave cavity body wall outside, is arranged on the locational cellular inlet air of microwave cavity body wall convection fan hole and the cellular exhaust vent that is arranged on microwave cavity body wall upper and lower; Be provided with the screen pack that filters oil smoke between microwave cavity body wall and convection fan, the periphery of screen pack is provided with the retainer ring that is used 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 a metal filter screen.
Described filter cotton is the activated carbon filtration cotton that is used to filter with clean air.
Advantage and good effect that the present invention has are:
Micro-wave oven hot air convection structure of the present invention can be roasted filtering oil smoke, and the toxic and harmful after the oil smoke decomposition is filtered and absorption, obtains clean air, is used to the heat food that circulates.The food that comes out of heating health and safety more guarantees the healthy of client like this, also makes the user obtain satisfied barbecue effect simultaneously.
