Stretch in furnace cavity 10 with after the first axis hole 111.
It is understood that micro-wave oven also includes rotary work part, rotary work part be positioned at furnace cavity 10 and with stretch into
Motor shaft 31 in furnace cavity 10 is connected, and motor 30 is used for driving rotary work part to rotate；Specifically, such as Fig. 3 to Fig. 6 institute
Show, rotary work part can for stirring flabellum 50, stirring flabellum 50 be positioned at furnace cavity 10, furnace cavity 10 include rear cavity plate
11st, left cavity plate the 12nd, right cavity plate 13 and lower cavity plate 14, it is preferable that the first axis hole 111, certainly, the first axis hole are set in rear cavity plate 11
111 can also be provided in right cavity plate the 13rd, left cavity plate 12 or lower cavity plate 14 according to demand, correspondingly, in the present embodiment, and axle sleeve 20
Being arranged in the rear cavity plate 11 of furnace cavity 10, motor shaft 31 passes through the first axle in the second axis hole the 22nd, choke chamber 21 and cavity plate
Being connected with stirring flabellum 50 in extending into furnace cavity 10 behind hole 111, stirring flabellum 50 is driven by motor 30 and rotates to drive furnace chamber
Air circulation in body 10, micro-wave oven still further comprises heating member 60, and it is interior for stove that heating member 60 is arranged on furnace cavity 10
Air-flow heating in cavity 10, and stir flabellum 50 when driving air circulate, the air in promotion furnace cavity 10 is at furnace cavity 10
It inside is uniformly distributed；Certainly, this programme is not limited by diagrammatically shown structure, it is possible to arranging rotary work part is rotating disk, cavity of resorption
Being provided with the first described axis hole on plate, axle sleeve is also disposed in lower cavity plate, and the inner side that rotating disk is positioned at lower cavity plate is cooked for holding
Prepare food object, motor shaft extend into after passing through the first axis hole in the second axis hole, choke chamber and lower cavity plate in furnace cavity with rotating disk phase
Even, rotating disk is driven by motor and rotates so that the culinary art object on rotating disk and the microwave uniform contact in furnace cavity.
Specifically, as depicted in figs. 1 and 2, hot blast assembly is arranged on stove to the micro-wave oven with hot blast function of prior art
In rear cavity plate 11' of cavity 10'.Specifically, hot blast assembly includes heating member 40', hot blast motor, stirring flabellum 20' and heat
Fan housing 30', heating member 40' are preferably hot blast heat-generating pipe, and heating member 40' is fixed on the inner side of rear cavity plate 11' of furnace cavity 10'；
Hot blast motor is fixed on outside cavity；The motor shaft of hot blast motor passes through rear cavity plate 11' of furnace cavity 10'；Stirring flabellum 20' sets
Put inside furnace cavity 10', be installed on hot blast motor shaft；Air bells cap 30' is fixed on inside rear cavity plate 11' of furnace cavity 10',
And be located on heating member 40' and stirring flabellum 20', air bells cap 30' is provided with return air hole 32' and wind pushing hole 31', wherein, is
Ensure its shield effectiveness, need to control the assemblage gap between air bells cap and rear cavity plate 11' of furnace cavity 10' 0.2mm with
In.
When start hot blast function when, hot blast driven by motor stirring flabellum 20' rotate, by the air within furnace cavity 10' from
Return air hole 32' on air bells cap 30' is drawn in the space between air bells cap 30' and rear cavity plate 11' of furnace cavity 10', air
After heated object 40' heating, then the wind pushing hole 31' from air bells cap 30' is discharged in furnace cavity 10', it is achieved furnace cavity 10' is empty
The circulating-heating of gas, thus the heating uniformity of the micro-wave oven improving.
In order to prevent the microwave in furnace cavity 10' from being exported to outside furnace cavity 10' by hot blast motor shaft, it is therefore desirable to

With, so, the size of wind pushing hole 41 and return air hole 42 is flexible with reference to air output Demand Design herein, thus improves cooking of product
Performance of preparing food and efficiency.
In sum, the micro-wave oven that the present invention provides, in the rear cavity plate 11 of furnace cavity 10, the installation position of motor 30 installs
Putting an axle sleeve 20, axle sleeve 20 is fixed on outside the rear cavity plate 11 of furnace cavity 10, and the inner surface of axle sleeve 20 constructs one one
End has the choke chamber 21 of opening, the opening of choke chamber 21 and the first axis hole 111 in the rear cavity plate 11 of furnace cavity 10 just to and
Communicating, the motor shaft 31 of motor 30 initially passes through axle sleeve 20, is then passed through the rear cavity plate 11 of furnace cavity 10, wherein, the height of axle sleeve 20
Size H, less than the 1/4 of microwave wavelength, with this, utilizes the filtration to microwave for the axle sleeve 20, can greatly shield in furnace cavity 10
Derive, from motor shaft 31, the microwave of coming, improve the security of product, and in micro-wave oven work, wind pushing hole 41 He on air bells cap 40
The size of return air hole 42 can not be limited by filtering requirements, carry out hot blast cook when, can adjust according to the circulation in air channel and send
Air holes 41 and return air hole 42 size, improve culinary art performance improving product efficiency.In addition, this programme arranges axle sleeve 20 and furnace chamber
The rear cavity plate 11 of body 10 is welded, and this technics comparing is easily controlled, and is beneficial to improve mounting process efficiency, and the structure of this programme
In, the installation requirement of air bells cap 40 in furnace cavity 10 is reduced, it is not necessary to considering that microwave passes through, its gap being arranged on cavity is also
Without carrying out technology controlling and process, can the packaging efficiency of improving product.
