The opening of above-mentioned guide duct one end is near fan, and the opening of the guide duct other end directly communicates with the hollow cavity of heating tube cover.
The sidewall of above-mentioned heating tube cover is made some through holes, and some through holes that the opening of the guide duct other end is made by the heating tube cover sidewall communicate with the hollow cavity of heating tube cover.
The main body of above-mentioned guide duct and one end and other end integral body are made, or the main body of guide duct, one end and the other end make respectively, link together again.
Above-mentioned heating tube cover is made separately, is packed in the top of housing again; Or heating tube cover is direct and the housing one is made.
Said fans is the cooling fan of microwave generation device, or special fan.
Above-mentioned heat-generating pipe is quartz ampoule or halide torch or metal electric heating pipe, or includes quartz ampoule and halide torch, or includes metal electric heating pipe and halide torch, or includes quartz ampoule, halide torch and metal electric heating pipe; Above-mentioned heat-generating pipe is made and is linear pattern, or makes and be flexure type.
Open ports has been made in the bottom of above-mentioned heating tube cover, and its open ports communicates with the cavity that housing is surrounded; Or the bottom of heating tube cover makes some through holes, and heating tube cover communicates with the cavity that housing is surrounded by some through holes.
The utility model is owing to adopt the opening of guide duct one end to communicate with the hollow cavity of heating tube cover, the other end of guide duct places and the corresponding locational structure of fan, guide duct near cooling fan can be blown over heat-generating pipe from the wind extraction part that cooling fan is produced by boasting, and the heat of heat-generating pipe brought in the microwave cavity by the top and the sidepiece of housing, promote in furnace chamber, to form cross-ventilation.Therefore; the utility model not only can make the furnace chamber temperature rise accelerate, and can to heat-generating pipe and on every side parts carry out cooling protection, reduce parts temperature requirement specification; prolong its service life, and the cooling fan that can be directly drives from cooling motor of its wind regime.The utility model is that a kind of design is ingenious, simple in structure, and cost is low, the effective micro-wave oven with baking function.
