Abstract
The invention discloses a rotating speed control method for a mixer, comprising the following step: realtimely obtaining weight information of a load in the mixer; obtaining a control algorithm corresponding to current load weight from a preset corresponding relationship list of load weights and control algorithms, and outputting corresponding speed control signals to a motor according to the control algorithm. As the load in mixer suddenly changes, the method can keep stable rotating speed, without adding any hardware cost, and the control precise is high.
Description
Technical field
The present invention relates to the stirring machine technology, relate in particular to a kind of stirring machine that is used for the method for controlling number of revolution of stirring machine and uses this method.
Background technology
At food blending machine, especially in the course of work of juice extractor, because the rotation rapidly of cutter, the load in the container may be beaten and fly or overflow, cause that load weight sharply changes, cause the motor speed instability.A lot of in the market stirring machines all have the electronic scales device, and this stirring machine can the variation of monitoring load weight in real time in its course of work, and still, it still can not solve the motor speed problem of unstable.
Summary of the invention
Technical matters to be solved by this invention is: a kind of method for controlling number of revolution that is used for stirring machine is provided, and this method can still keep stabilized (steady-state) speed under stirring machine internal burden situation jumpy, need not increase any hardware cost, and the control accuracy height.
The further technical matters to be solved of the present invention is: a kind of stirring machine is provided, and this stirring machine can still keep stabilized (steady-state) speed, the control accuracy height under stirring machine internal burden situation jumpy.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
A kind of method for controlling number of revolution that is used for stirring machine may further comprise the steps:
Obtain stirring machine internal burden weight information in real time;
From default load weight and the tabulation of conduction angle corresponding relation, obtain the control algolithm corresponding, and export the speed control signal of correspondence according to this control algolithm to motor with present load weight.
Wherein, described stirring machine internal burden weight is obtained by electronic scales.
Preferably, the controlled variable of described control algolithm is a conduction angle.
Correspondingly, the present invention also provides a kind of stirring machine, include electronic scales, controller and be used to drive the motor that cutter rotates, described controller includes rotary speed controling unit, be used for obtaining real-time load weight information, and reach the rotating speed that matches according to described weight information control motor from described electronic scales.
Wherein, described rotary speed controling unit specifically includes:
Data capture unit is used for obtaining present load weight from electronic scales;
