Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples.
Embodiment 1
Referring to Fig. 1-Fig. 5, the present embodiment includes annular cooking cavity 1, dual rotary grill 2, driving motor 3, electric control gear 4, described
Grill 2 include chassis 2.1, column 2.2, upper beam 2.3, combination carrier 2.4, wherein combination carrier include annular upper cover 2.41,
Gear 2.42 and lower cover 2.43,2.412 outside of inner wall of the annular upper cover 2.41 is driven to be equipped with and above-mentioned driving gear
The biting teeth of 2.42 occlusions, for when driving gear 2.42 to be rotated with grill 2, it being made to generate the rotary motion around own axes,
The inside of the inner wall 2.412 of the annular upper cover 2.41 is equipped with counterweight beam 2.413, and sagging match is equipped at the center of the beam
2.414 are weighed, the rotary inertia for increasing upper cover, when barbecue, by transformation 3 speed of service of driving motor in due course of electric control gear 4,
So that grill 2 is broken away from following for the upper cover 2.41 of combination carrier mounted, makes upper cover 2.41 and above-mentioned 2.42 phase of driving gear
To rotary motion.Specifically, the driving motor 3 is direct current generator, and the electric control gear 4 is including CPU and with adjustable three
It is the motor speed stabilizing of core, alignment circuit, the output of the power positive end and LM317 of driving motor 3 to hold integrated regulator LM317
2 connection of end, the power supply negative terminal of driving motor 3 connects power ground by one 1 ohm of wire resistor R1, by resistance R1 and resistance R2,
R3 is converted into the variation of the load current of driving motor 3 voltage change of A points, and A points are connected to through isolation resistance R4 and are adopted with CPU
The output voltage UO for the output end B, LM317 that sample input terminal IO1 is connected=(1+ (R6+R7)/R5) * 1.25, adjustment can power transformation
The resistance value for hindering R7 and R6, it is V2=10r/min to make grill rotating speed, and the rotating speed of corresponding driving motor 3 is μ 2, grill when making R7 short circuits
Rotating speed is V1=4r/min, and the rotating speed of corresponding driving motor 3 is μ 1, and the IO2 of the CPU, which is an inside, has pull-up resistor
Output port, CPU be internally integrated hardware A/D converter the analog sampling signal of input port IO1 can be changed into it is corresponding
Digital signal, when barbecue, according to the Initialize installation of software program, when driving motor 3 starts, IO2 be in high potential, and T1 is saturated
Conducting, R7 is short-circuited, and driving motor 3 drives grill 2 to rotate with rotating speed μ 1, since the upper cover 2.41 of the combination carrier can be with
Rotated relative to grill 2, cannot rising to and rise to grill rotating speed, there are one the processes being gradually reduced for the two speed discrepancy so that
Combination carrier upper cover 2.41 is relatively rotated with the driving gear 2.42 for combining carrier, and the driving gear 2.42 for realizeing combination carrier exists
While around the axis rotation of grill 2, rotate around own axes, corresponding combination carrier upper cover 2.41 and 2 speed discrepancy of grill by
Decrescence small, the voltage of A points gradually subtracts after startup is leapt high in the load current and motor speed stabilizing, alignment circuit of driving motor 3
Small, when current CPU is less than 5 millivolts to the absolute value of the difference ︱ VN-VN+1 ︱ of the front and back double sampling value of A point voltages, IO2 outputs are low
Level, T1 cut-offs, the rotating speed of driving motor 3 rise to μ 2 with rising to for LM317 output voltages, and grill 2 is with rotating speed V2=10r/mi
Rotation, since the rotating speed of the combination carrier upper cover 2.41 cannot rise to 2 rising to for rotating speed of grill, the two speed discrepancy is again
It is secondary to be widened, drive the rotation of gear 2.42 to inject new power for combination carrier, when combination carrier upper cover 2.41 and grill 2
Rotating speed moves closer to, when CPU is less than 5 millivolts to the absolute value of the difference ︱ VN-VN+1 ︱ of the front and back double sampling value of A point voltages, IO2
Export high level, T1 saturation conductions, R7 is short-circuited, and the rotating speed of driving motor 3 returns to μ 1, the rotating speed of grill 2 drop to rapidly V1=
The rotating speed of 4r/min, the combination carrier upper cover 2.41 cannot be kept up with rapidly, and the speed discrepancy of the two is widened again, Deng Daoshang
The speed discrepancy stated is gradually reduced so that CPU is small to the absolute value of the difference ︱ VN-VN+1 ︱ of the front and back double sampling value of A point voltages
When 5 millivolts, IO2 exports low level, T1 cut-offs, and the rotating speed of driving motor 3 rises to μ 2 with rising to for LM317 output voltages,
Grill 2 is rotated with rotating speed V2=10r/mi again ... ... and so on, checker, constantly drives gear 2.42 for combination carrier
Rotation inject power, realize driving gear in the case where not converting the steering of driving motor 3, uninterrupted grill 2 rotating
2.42 rotate while keeping around the axis rotation of grill 2 around own axes, to make hanging in the food docked with its lower end
Food on object carrier is under dual rotary barbecue pattern always.Compared with prior art, the present embodiment is solved due to driving
The technical issues of motor 3 is caused using commutation or intermittent operation mode, it can be achieved that whole bispin rotary-die type, has and improves barbecue
Uniformity extends driving motor service life, reduces requirement to motor overload ability, reduce energy consumption, improve dual rotary barbecue
The practicability and applicability of device, the Advantageous achievement such as reduce cost.
Embodiment 2
Compared with Example 1, difference is essentially consisted in untouchable Hall current sensor HS1 instead of implementation the present embodiment
The effect of R1 in example 1, R1 are to be converted into load current to be convenient for the voltage signal of sampling, value being a dilemma, resistance
It is worth that small sampled voltage dynamic range is too small, and resistance value had not only been unfavorable for greatly voltage stabilizing speed stabilizing, but also is unfavorable for reducing energy consumption, Hall electricity
Flow sensor HS1 is made of altogether around a magnetic core the power cord of driving motor 3 and induction coil, and sampled signal is induced electricity
Stream, substituting R1 with it has the advantages that sampled signal wide dynamic range, does not consume electric energy.Remaining, is not directed to place and embodiment 1
It is identical.
It should be pointed out that every equivalent transformation done using description of the invention and accompanying drawing content or identical essence
The different expression of meaning, and other related technical areas are directly or indirectly used in, in patent protection model of the invention
In enclosing.
