It is entered inside cooking chamber 8 by air inlet hole 9.In addition, end plate 5 is obliquely installed, and as shown in Figure 7, Figure 8, end plate 5 and side plate 6
Angle is obtuse angle, is acute angle positioned at the wind deflector 2 of first position and the angle of end plate 5, and driving wheel 11 is located substantially at end plate 5 and the
Between the wind deflector 2 of one position, the eccentric shaft 12 on driving wheel 11 rotates between the wind deflector 2 of end plate 5 and first position, with
Wind deflector 2 is driven to rotate.
Further, the top edge of wind deflector 2 is equipped with flange 20, is formed on flange 20 and prolongs along the top edge of wind deflector 2
The strip-shaped hole 21 stretched, driving wheel 11 are arranged across top plate 3, and eccentric shaft 12 is inserted into strip-shaped hole 21 along the vertical direction.Wind deflector 2
Top edge is the edge of neighbouring top plate 3, strip-shaped hole 21 is formed on flange 20, driving wheel 11 passes through top plate 3, thus eccentric shaft 12
It can be inserted in strip-shaped hole 21, when driving wheel 11 rotates, eccentric shaft 12 is also accordingly around the central axis of driving wheel 11
Rotation, meanwhile, eccentric shaft 12 acts on the side of strip-shaped hole 21 and wind deflector 2 is driven to rotate, wherein when eccentric shaft 12 rotates,
Eccentric shaft 12 slides in strip-shaped hole 21.Two edges up and down of wind deflector 2 can be respectively formed flange, can install on flange
Wind deflector 2 is articulated with wind scooper 1, such as is hinged on bottom plate 4 and top plate 3 by shaft.
In addition, as shown in Figure 4 and Figure 5, the micro-wave oven includes microswitch 13, and microswitch 13 is connected to motor 10
The outer peripheral surface of control circuit, driving wheel 11 is equipped with lug boss 14, when wind deflector 2 is located at the first position and second
When setting, lug boss 14 triggers microswitch 13, and the control circuit control motor 10 is closed.Microswitch 13 can play feedback
Effect feeds back the information that wind deflector 2 reaches the first position and the second position to control circuit, so that motor 10
It can in time stop, wind deflector 2 is maintained at the first position or the second position.The setting of lug boss 14 is driving
On the outer peripheral surface of wheel 11, when wind deflector 2 reaches the first position or the second position, lug boss 14 can be pressed micro-
On the contact of dynamic switch 13, so that the off state of microswitch 13 changes, so that the location information of wind deflector 2 be transmitted
To the control circuit.
In addition, the front of the micro-wave oven is equipped with the air inlet 15 being connected to circulation air path 24, the bottom of the micro-wave oven
Equipped with the air outlet 16 being connected to circulation air path 24.As shown in Figures 2 and 3, the cabin of micro-wave oven front is arranged in air inlet 15
On plate, air outlet 16 is arranged on the cabin plate of microwave furnace bottom.As shown in fig. 6, wind deflector 2 be located at the second position and with culinary art
Room 8 keeps interval, and a part of air-flow from circulation air path can enter cooking chamber 8 via the air inlet hole 9 in cooking chamber 8
In, another part air-flow can continue flowing in circulation air path 24 and be discharged via air outlet 16；As shown in figure 9, wind deflector 2 pastes
Together in cooking chamber 8, after the air-flow from circulation air path 24 reaches wind scooper 1, it not can enter and cook under the barrier effect of wind deflector 2
It prepares food room 8, it is dynamic and be discharged via air outlet 16 that air-flow turns to subsequent afterflow.
Specifically, fan 17, magnetron 18 and transformer 19 are provided in circulation air path 24.Fan 17 can be air-flow
Circulation provides power, and magnetron 18, transformer 19 (or frequency converter) etc. generate the electric elements of heat during the work time, can
To be radiated by circulating current, avoids electric elements temperature excessively high and be not normally functioning.Wherein, fan 17, magnetron
18 and the gas flow temperature that can be set in the upstream of wind scooper 1, into wind scooper 1 of transformer 19 it is relatively high, into cooking chamber 8
In influence to cooking process it is smaller, air-flow can carry plus thermogenetic water vapour is discharged to outside cooking chamber 8, reduce product
Water, product mist.
As shown in figure 3, fan 17, transformer 19 are located at the bottom of the electrical store, and magnetron 18 is located at electrical store
After air-flow is blown to 19 by fan 17, under the action of wind-guiding bracket 22, air-flow is transmitted at the magnetron 18 on top for top,
Subsequent air-flow reaches wind scooper 1, and air-flow passes through the guidance of wind scooper 1, turns to downwards and is discharged via air outlet 16.Wind scooper 1
It can be installed in the outside wall surface of cooking chamber 8.
In addition, wind deflector 2 is equipped with gasket seal 7 towards the surface of cooking chamber 8.Gasket seal 7 can be made of silica gel,
Or other materials resistant to high temperature, gasket seal 7 can more fully seal the air inlet hole 9 in cooking chamber 8, avoid in cooking chamber
Heating air leakage.Gasket seal 7 can be plugged on wind deflector 2, and can according to need replacement.
Specifically, the micro-wave oven can be run under microwave mode and hot wind mode, under the microwave mode, wind-guiding
Plate 2 is located at the second position, and under the hot wind mode, wind deflector 2 is located at the first position.In the microwave mode
Under, micro-wave oven is heated by microwave to indoor food etc. is cooked, and be can permit a small amount of air-flow at this time and is entered culinary art
Chamber interior is simultaneously discharged, and thermogenetic water vapour will be added to be discharged, and influence of the air-flow to heating process is smaller；In the hot wind mode
Under, micro-wave oven is by the food etc. in Hot-blast Heating cooking chamber, if still thering is outer gas stream to enter in cooking chamber and being discharged,
This can significantly affect heating efficiency, therefore, it is necessary to close the air inlet hole 9 in cooking chamber 8 by wind deflector 2, improve heating efficiency.
Wherein, by designing relevant control circuit and control panel, can pass through when user selects microwave mode or hot wind mode
Motor 10 drives wind deflector 2 to reach corresponding position.
It is described the prefered embodiments of the present invention in detail above in conjunction with attached drawing, still, the present invention is not limited thereto.At this
, can be with various simple variants of the technical solution of the present invention are made in the range of the technology design of invention, including each particular technique
Feature is combined in any suitable manner, and in order to avoid unnecessary repetition, the present invention is to various combinations of possible ways
No further explanation will be given.But it should also be regarded as the disclosure of the present invention for these simple variants and combination, belongs to the present invention
Protection scope.
