Fig. 1 show the schematic diagram of one embodiment of cooking machine motor rotation blockage protection device 10.Cooking machine motor rotation blockage
Protection device 10 can be used for cooking machine, such as broken wall cooking machine, soy bean milk making machine, juice extractor etc., for detecting the stall feelings of motor
Condition.Cooking machine motor rotation blockage protection device 10 includes Rotating speed measring circuit 11 and controller 12.
Rotating speed measring circuit 11 includes rotating speed output end Speed, is believed by rotating speed output end Speed output motor rotating speeds
Number.Motor speed can be directly or indirectly obtained from motor speed signal.In the illustrated embodiment, Rotating speed measring circuit 11 wraps
Hall sensor 112 is included, produces motor speed signal.Motor 13 includes rotor, and magnet 14 is fixedly installed on rotor.Hall passes
Sensor 112 is near magnet 14, and when motor 13 rotates, magnet 14 can be with certain cycle close to Hall sensor 112.Suddenly
The magnetic field that your sensor magnet 14 of sensor 112 is rotated and changed with rotor, produces motor speed signal.When magnet 14 is close to Hall
During sensor 112, Hall sensor 112 exports high level.When magnet 14 is away from Hall sensor 112, Hall sensor 112
Export low level.So as to which Hall sensor 112 produces the pulse signal of square wave.In the present embodiment, motor speed signal is side
The pulse signal of ripple.It can be calculated according to the pulse signal and obtain motor speed.
In the illustrated embodiment, Rotating speed measring circuit 11 includes first resistor R1, is series at the output of Hall sensor 112

Panel.
Fig. 2 show the schematic diagram of one embodiment of cooking machine motor rotation blockage guard method 20.In step 21, cooking
Electric on machine, motor is started working.In step 22, each preset time period collection motor speed V.For example, the collection electricity per 100ms
Machine rotating speed.Motor speed can calculate acquisition according to the mode being outlined above.
In step 23, judge whether motor speed V is less than rotary speed threshold value.If motor speed V is not less than rotary speed threshold value, really
Determine motor normal work, stall, which reports an error, counts Cnt equal to 0, step 24, and enters step 22, continues to gather motor speed.It is if electric
Machine rotating speed V is less than rotary speed threshold value, then stall report an error count Cnt add 1, step 25.
In step 26, stall, which reports an error, counts after Cnt adds 1, judges that stall reports an error and counts whether Cnt is more than count threshold,
Such as count threshold is 30.If stall reports an error counting, Cnt is not more than count threshold, into step 22, continues to gather motor turn
Speed.If stall reports an error counting, Cnt is more than count threshold, it is determined that motor is in locked rotor condition.Represent multiple continuous pre-
If motor speed is below rotary speed threshold value in the period, determine that motor is in locked rotor condition.In step 27, during locked rotor condition,
Controlled motor is stopped.In one embodiment, during locked rotor condition, controlled motor is stopped and shows motor rotation blockage failure
Code.Step 22-27 can be performed by controller 12.
