Specific implementation mode
The present invention is described in further details with reference to preferred embodiment, is elaborated in the following description more
Details to facilitate a thorough understanding of the present invention, still, the present invention obviously can be come with a variety of other modes different from this description
Implement, those skilled in the art can without violating the connotation of the present invention according to practical situations make it is similar promote,
It deduces, therefore should not be limited the scope of the invention with the content of this specific embodiment.
Fig. 1-2 is the schematic diagram of the embodiment of the present invention, it should be noted that this attached drawing only as an example, not be by
It draws, and should not be construed as limiting in this, as the actual requirement protection domain to the present invention according to the condition of equal proportion.
Existing microwave oven turntable rotation angle control structure is complicated, higher to equipment requirement to cause cost higher.In order to
A kind of simple in structure and lower microwave oven turntable of cost is provided, the technical program provides the microwave oven turntable of rotary steerable,
Including the turntable body 10 being arranged in micro-wave oven casing, which, which is driven by shaft 11 by driving motor, rotates,
Wherein, the bottom of the turntable body 10 is additionally provided with velometer 31 and catch 21；
The catch 21 by stepper motor 26 control rotation angle, the rotation angle be 0-90 °, the catch 21 with turn
When disk ontology 10 is vertical, which is absorbed in the locating slot 22 of 10 bottom of turntable body；
The catch 21 is rotated around locating support 24, and the catch 21 is connect by belt 25 with stepper motor 26；
