The specific embodiment
Below in conjunction with the drawings and specific embodiments air flow guide apparatus for microwave oven of the present invention is described in further detail: we can see according to air flow guide apparatus of the present invention in Fig. 2.As shown in the figure, electric control chamber 10 inside are provided with the magnetron 12 that produces microwave and can make the blowing fan 14 of the generation air stream of magnetron heat radiation.
There is the heating clamber that forms by a lot of passages that links to each other with heating clamber to enter the mouth 20 on the sidewall 42 of electric control chamber 10.The air stream that produces in blowing fan 14 will cool off them through magnetron 12 and transformer etc. the time.
Subsequently, the air stream that cools off above-mentioned parts will flow into heating clambers by the heating clamber inlet 20 that is positioned at sidewall 42.
Below, have a look at the structure that opens and closes heating clamber inlet 20 again.Heating clamber inlet 20 is positioned on the sidewall 42, and coming down to has a lot of passages in the part of sidewall 42.
Opening-closing plate 50 among the present invention can open and close heating clamber inlet 20, opening-closing plate 50 is simple template, blocks heating clamber when opening-closing plate 50 and enters the mouth 20 the time, and air stream just can't enter heating clamber inside, in case opening-closing plate 50 separates with heating clamber inlet 20, air stream just can enter heating clamber inside.
Fluently used the simplest template opening-closing plate in order to control the air that flows into the heating clamber inlet in the present invention, this essence is to use comparatively simple structure more effectively to control air stream.
Opening-closing plate 50 1 ends have connecting axle 52, and around connecting axle 52 is center steering, the heating clamber inlet is positioned on the sidewall 42, in fact connecting axle 52 can not be axle, so long as constitute opening-closing plate 50 1 ends just can, and with sidewall near contacting or contact, enter the mouth 20 with upper and lower to being arranged on heating clamber as the center of rotation of opening-closing plate 50, the position of center of rotation is at the end of opening-closing plate away from blowing fan M, and the air of control heating clamber inlet 20 flows the amount with air stream.
Connecting axle 52 links to each other with drive motors M, and along with the action of drive motors M, opening-closing plate 50 will be that rotate at the center with connecting axle 52.The rotation of opening-closing plate is actually and opens and closes heating clamber inlet 20.
Below, will the work according to air flow guide apparatus of the present invention with above-mentioned structure be described.At first, in fact there is no need allowing air flow when the convection heater that utilizes micro-wave oven inside heats the food that enters heating clamber inside crosses blowing fan and enters heating clamber inside.So under this situation, make opening-closing plate 50 block the heating clamber inlet 20 of sidewall 42 by drive motors M.That is to say that the air stream in the blowing fan can't enter heating clamber inside in this case.
When utilizing heating using microwave food, then be necessary air to be flow to into heating clamber inside by blowing fan.Since the driving of drive motors make opening-closing plate with the connecting axle be the center rotate make opening-closing plate and heating clamber enter the mouth from. as shown in Figure 2, when the opening-closing plate oppose side wall forms near an angle of 90 degrees, the air stream that forms in blowing fan will flow into heating clamber by the heating clamber inlet after the cooling magnetron.
The air stream that flows into heating clamber inside will be arranged to the outside along with the inner steam that produces of heating clamber.
In the present invention, fluently used the template opening-closing plate in order to control the air that enters the heating clamber inlet.Opening-closing plate mainly is to be responsible for opening and closing the heating clamber inlet.But in fact, can adjust the amount of the air stream that enters the heating clamber inlet according to the angle of release of adjusting opening-closing plate.
With the sidewall is that benchmark is compared the state that opening-closing plate reaches more than 90 degree with the state of the acute angles that opening-closing plate reached about 50 degree, and we can know, the introducing heating clamber inlet that the stream of the air in the blowing fan can be concentrated more when in fact being split into acute angle.So when opening-closing plate flows except opening and closing heating clamber inlet control air, also can probably adjust the amount of air stream.Certainly, the control of the revolution of motor is depended in the adjustment of the switching angle of opening-closing plate.
