Above-mentioned first heat-generating pipe and second heat-generating pipe are controlled it by the micro-wave oven control device and are worked alone respectively, or control it by the micro-wave oven control device and work simultaneously.
The opening of above-mentioned guide duct one end is near fan, and the opening of the guide duct other end directly or by some holes communicates with a side of housing.
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.
Said fans is the cooling fan of microwave generation device, or special fan.
Above-mentioned heating tube cover sidewall or end face make open ports or some holes communicate with the cavity that guide duct is surrounded.
The present invention is owing to adopt a heat-generating pipe to be supported on the top of housing by heating tube cover, another heat-generating pipe places the side of housing, guide duct is trapped among heating tube cover, the outside of two heat-generating pipes, the opening of guide duct one end place with the corresponding position of fan on, the structure that the other end and a side of housing connect mutually, a part of wind that cooling fan is produced by boasting is blown over heating tube cover and heat-generating pipe by guide duct, and the heat of heating tube cover is surperficial and heat-generating pipe is brought in the microwave cavity by the top and the sidepiece of housing, promotion air in furnace chamber flows, accelerate the even of heat distribution, and top heat-generating pipe and side heat-generating pipe can work alone, and can the duty of top heat-generating pipe and side heat-generating pipe be set according to the difference needs of cooking.Therefore; the present invention not only can make the rising of furnace chamber temperature accelerate; and can carry out multiple working group with to satisfy the culinary art needs of different foods; 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.When the heat-generating pipe of upper top of the present invention was worked, heat-generating pipe was realized " barbecue " function by the radiation mode heat food, when the heat-generating pipe of its side is worked, cure heat food by air heat is imported cavity, realize " hot air convection " function, the present invention has realized a complete barbecue hot air convection structure, compare with traditional hot air convection structure, cost reduces greatly, is that a kind of design is ingenious, simple in structure, cost is low, effective novel microwave oven.
