Abstract
A hot air convection type microwave oven comprises an oven cavity, a microwave generator, a heating pipe, a heating pipe cover and an upper cover plate. The heating pipe cover is arranged at the roof part of the upper cover plate; the heating pipe is arranged in the cavity of the heating pipe cover; an air guiding mechanism is arranged beside the heating pipe cover and communicates through an air guiding mesh; hot air fan blades are connected in the air guiding mechanism through a sliding bearing transmission connector; a plurality of air guiding holes communicated with the oven cavity is arranged on the upper cover plate correspondingly to the hot air fan blades. The roof wall of the oven cavity is added with an air guiding device which sucks cold air in the oven cavity; the cold air is heated by the heating pipe, and the hot air is blown into the cavity; the position of sucking the cold air and the position of blowing the hot air are separated so as to realize cold and hot air circulation. Because the cold air in the working microwave oven has a certain temperature, the cold is re-heated by the heating pipe to quickly reach the set temperature so as to avoid heat loss and improve working efficiency. The microwave oven has a simple and reasonable structure, high energy efficiency, low noise and a low manufacturing cost, and uniformly heats and is easily cleaned.
Description
Technical field
The present invention relates to a kind of micro-wave oven, particularly with the hot air convection type ripple stove of air scoop.
Background technology
In general, micro-wave oven is with microwave food to be heated.Common microwave stove is to utilize the food molecule cooked to be subjected to the effect of alternating electromagnetic field in micro-wave oven furnace chamber, high frequency motion takes place, and the principle of molecule and intermolecular frictional heat is come heat food.But the efficiency of heating surface of these micro-wave ovens is lower, and people begin to consider to increase other heating function of micro-wave oven, improves the efficiency of heating surface of micro-wave oven.Increase other heating functions, can make the increased functionality of micro-wave oven.A period of time people are in order to seek to obtain the more beautiful color of microwave cooked food recently, on the basis of single microwave function, increased other function gradually, develop micro-wave oven in succession with baking function, the micro-wave oven that has the hot air convection formula in addition, the function of micro-wave oven is increased greatly, have stronger heating function, have the higher efficiency of heating surface.Convection-microwave oven is except that reservation utilizes the major function of microwave cooked food, also have by the circulate function of cooking food of electric heater unit and the air circulation device mode by radiation, convection current, not only can utilize microwave energy from the inside to the outside, equably, boil up hill and dale with food, and can utilize heat radiation that electric heater unit produces, surface that hot air convection makes food slightly burned, have tempting outward appearance and good sense of taste, also can boil food apace.But the micro-wave oven air draught of hot air convection is same device is finished air draught and exhausting in the different time periods operation with exhausting now, the result of these hot air convections is exactly, make gas hot blast and cold wind in the cavity be inhaled in the heating cavity together, hot blast and cold wind in the cavity are separated simultaneously, promptly suck in the heating cavity is cold wind, being drained in the microwave oven cavity is hot blast, can not make the hot blast and the really exchange circularly of cold wind of the inside of micro-wave oven.Temperature in the furnace chamber of micro-wave oven rises unhappyly, and temperature distributing disproportionation interior in the furnace chamber is even, and noise is also than higher simultaneously.
Summary of the invention
Purpose of the present invention is intended to provide a kind of cold wind suction to separate with the lane place that hot blast is blown into, can realize that cold and hot wind circulates veritably, make the temperature in the micro-wave oven furnace chamber body rise soon, uniformity of temperature profile in the cavity, the also lower hot air convection type ripple stove of while noise is to overcome weak point of the prior art.
A kind of hot air convection type ripple stove by this purpose design, comprise furnace chamber, microwave generator, heat-generating pipe, heating tube cover and upper cover plate, the top of upper cover plate is provided with heating tube cover, heat-generating pipe places in the cavity of heating tube cover, its architectural feature is that the heating tube cover side is provided with air guide mechanism, and communicates by the wind-guiding mesh; Be connected with the hot blast flabellum by the sliding bearing device that is in transmission connection in the air guide mechanism, the corresponding hot blast flabellum of upper cover plate is provided with some air-guiding holes and communicates with furnace chamber, with cold cycling, hot air convection in the realization furnace chamber.Because air moves in order in the furnace chamber, so temperature is even, noise is low.
Described air guide mechanism is the open air scoop in a bottom surface and a side, and bottom surface and open side communicate with furnace chamber and heating tube cover respectively; Be provided with the hot blast flabellum in the air scoop, hot blast flabellum and the sliding bearing device that is in transmission connection is connected, and by motor and belt transmission.
The described sliding bearing device that is in transmission connection includes support, bearing, sheet spring and fixed mount, fixed mount by the sheet spring with bearing fixing in support, form a bearing assembly, power transmission shaft is positioned at up and down between two bearing assemblies, and with sliding bearing of fixedly connected two the support formation up and down of rivet device that is in transmission connection.Power transmission shaft middle part is provided with step, is located by connecting on sliding bearing and is in transmission connection in the device.Wherein, the sheet spring play one reset, cushioning effect.
Increase gas operated device on the micro-wave oven furnace chamber roof of the present invention, cold wind in the furnace chamber is sucked, by the heat-generating pipe heating, hot blast is blown into cavity, cold wind sucks the lane place that is blown into hot blast to be separated, and realizes cold cycling.Because the cold wind in the micro-wave oven in the work also has certain temperature, heats once more through heat-generating pipe, reaches institute's fixed temperature rapidly, avoids thermal losses, increases work efficiency.It is simple and reasonable, homogeneous heating, efficiency height, noise is low, the cost cost is low.
