Technical field
The invention relates to a kind of soymilk grinder control circuit, especially a kind of soymilk grinder control circuit with electric machine soft starting function.
Background technology
The pulverizing motor of existing soy bean milk making machine adopts relay to control, and during electric motor starting electrical network is impacted greatly, and the noise that outburst is suddenly simultaneously come out is very big, the human body sense of hearing is produced frighten, especially to child and pet.Motor is also very poor to the applicability of line voltage in addition, and the high more motor power output of voltage is big more, and motor noise is greatly also along with increase, influence electrical machinery life, motor speed was low when voltage was low, and bean or pea can not fully be pulverized influences pulping rate, and the mechanical electric life-span of relay is also limited simultaneously.
Therefore, be necessary the circuit for controlling motor of existing soy bean milk making machine is improved.
Summary of the invention
Therefore the object of the present invention is to provide a kind of soymilk grinder control circuit with electric machine soft starting function, it controls motor by circuits for triggering unit controls reverse-blocking tetrode thyristor, can realize the soft start of motor, reduce the electric motor starting noise, prolong electrical machinery life, reduce influence, and the voltage that can change motor regulates motor speed, be suitable for different electrical network conditions environment and electrical network.
According to above-mentioned purpose of the present invention, a kind of soymilk grinder control circuit with electric machine soft starting function is proposed, comprise motor, output connects the reverse-blocking tetrode thyristor of motor, the circuits for triggering unit that connects the control end of reverse-blocking tetrode thyristor, the single-chip microcomputer that connects the circuits for triggering unit, the zero passage detection unit that connects single-chip microcomputer, and the supply voltage detecting unit of connection single-chip microcomputer, the input of reverse-blocking tetrode thyristor connects an electrode of power supply, and the end that motor is not connected with reverse-blocking tetrode thyristor connects another electrode of power supply, the supply voltage detecting unit connects the two poles of the earth of power supply, and single-chip microcomputer is connected with power supply by a power supply reduction voltage circuit unit.
The present invention has the soymilk grinder control circuit of electric machine soft starting function and controls motor by circuits for triggering unit controls reverse-blocking tetrode thyristor, can realize soft start, shock effect reduces to electrical network when starting to make motor, the noise that outburst is suddenly come out in the time of also can making electric motor starting becomes steadily, reduces the stimulation that the human body sense of hearing is produced.Also can offer the different voltages of motor in addition and regulate motor speed, adapt to different beans material and the user requirement to different degrees of grinding, different shredding stages can adopt different rotating speeds, improves pulping rate, and the silicon controlled comprehensive life is longer than relay simultaneously.
Description of drawings
Below in conjunction with accompanying drawing,, will make technical scheme of the present invention and other beneficial effect apparent by the specific embodiment of the present invention is described in detail.
In the accompanying drawing,
Fig. 1 has the schematic diagram of the soymilk grinder control circuit of electric machine soft starting function for realizing the present invention;
Fig. 2 is the work schematic diagram of one embodiment of the invention reverse-blocking tetrode thyristor by the copped wave triggering mode;
