Description

Method and apparatus for controlling motor rotation speed of juicer, mixer, and crusher.

The present invention relates to a method and apparatus for controlling the rotational speed of a motor of a juicer, a mixer, and a grinder, and more particularly, the present invention relates to a juicer for varying the motor rotational speed of a juicer, a mixer, and a grinder to properly grind materials. The present invention relates to a method of controlling a motor rotational speed of a mixer and a grinder, and an apparatus thereof.

As shown in FIG. 1, a conventional mixer includes an alternating current (AC) for supplying operating power to the mixer and a switch (SW6) for adjusting the rotational speed of the motor (M) by adjusting the power supplied to the motor (M). (SW7) and a grinding blade is attached to the end of the rotating shaft, and is composed of a motor M driven by the AC power source AC.

Such a conventional mixer, when one of the switches SW6 (SW7) is switched on to drive the mixer, the AC power supply AC is supplied to the motor M via the switches SW6 (SW7). The motor M rotates. Accordingly, the grinding blade mounted on the rotating shaft of the motor M rotates in conjunction with the grinding shaft to pulverize the material introduced into the mixer. In particular, since the resistance values of the resistors R11 (R12) to which the switches SW6 (SW7) and the motor M are connected are set differently, the motor (according to the level of the AC power source AC supplied to the motor M) The rotation speed of M) can be adjusted.

However, the mixer does not control the rotational speed of the motor in various ways depending on the material to be crushed because the power supplied to the motor is selected by only two switches. In other words, the grinding degree should be different according to the material to be crushed and the purpose of use. However, since the rotational speed of the motor cannot be arbitrarily adjusted, the user has to check the grinding degree visually and then adjust the AC power supplied to the motor. .

In addition, when vegetables grind fruits and crush them with too strong rotational force, the nutritional value contained in the ingredients is destroyed, which leads to the inability to obtain nutritious and high juices.

The present invention has been made to solve the troublesome problem as described above, the object is to adjust the motor rotation speed of the juicer, mixer, grinder in various ways to properly grind the material according to the type or purpose of the material It is to provide a method and a device for controlling the motor rotation speed.

In order to achieve the above object, the present invention provides a key input checking step of checking whether there is a key input in a key input standby state, a power flag set step of checking whether a power flag is set if the key is input, and a motor driving step if the power flag set is set. A power off key check step of returning or checking whether the power off key is applied; a motor drive stop step of outputting a low signal to the motor driver to stop the motor drive if the power off key is applied; Checking the momentary operation key check step, the motor driving step of driving the motor by outputting a high signal to the motor driving part if the momentary operation key is pressed, and checking the key off at the same time as the motor driving and returning to step S9 if the key is off. Otherwise, the key off check step returns to step S5, and if it is not a momentary key, the power flag is set and the motor is driven. A motor drive step of driving a motor by outputting a high signal to the motor, and a pass path step of checking whether the motor speed is 30-sec. Pass at the same time as the motor drive, or returning to step S14. The motor stop step of outputting to stop the motor drive, and if the motor speed is 20-sec pass, the step is returned to step S3, and if not the 20-pass pass, it is characterized in that it consists of a step pass to return to step S17.

FIG. 3 is a flowchart according to the present invention. As shown in FIG. 3, a key input checking step S2 for checking whether there is a key input in the key input standby state S1, and a power flag set for checking whether a key input is present is performed. The power flag set step (S3), if the power plug set is returned to the motor drive step, otherwise the power off key check step (S4) for checking the power off key is applied, and if the power off key, the low signal is output to the motor driver ( S5) the motor driving stop step (S6) for stopping the motor driving unit, the instantaneous operation key checking step (S7) for checking the application of the momentary operation key if it is not the power-off key, and if the momentary operation key is a high signal, S8) A motor driving step (S9) for driving the motor, and a key off check step (S10) at the same time as the motor driving (S10) and the key off check step (S11) to return to step S9 if the key is off and to return to step S5 if the key is off. Wow If the operation key is not set, the power flag is set (S12) and a high signal is output to the motor driving unit (S13). The motor driving step (S14) for driving the motor, and a check for checking whether the motor speed is 30 sec. If the motor drive stops (S17) to stop the motor drive by returning to the pass step (S15), or returning to step S14, and outputting a low signal to the motor drive (S16) in the case of 30-sec pass, and if the motor speed is 20-sec pass, It returns to step S3, and if not 20 sec pass, it consists of a neck pass step (S18) to return to step S17.

Referring to the operation and effect of the present invention configured as described above, the microprocessor 400 when selecting the material or the degree of grinding to operate by operating the key input unit 300 while supplying the operating power to the set output from the power supply unit 100, ) Reads the drive data (or program) corresponding to the material or purpose selected by the algorithm stored in the data storage unit 700 and based on the drive signal (for example, PWM pulse, etc.) Is printed). Accordingly, the AC power supplied to the motor is controlled by the motor speed controller 600 receiving the driving signal output from the microprocessor 400 to adjust the rotation speed of the motor according to the material or the purpose of use.

While driving the motor, the microprocessor 400 counts the clock pulse supplied from the clock oscillator 200 to count an operation time, and when the driving time corresponding to the algorithm stored in the data storage unit 700 is reached, the speed controller The rotation of the motor is stopped by blocking the driving signal output to the 600.

This will be described in more detail based on the flowchart of FIG. 3. First, in order to grind a specific material, in the state of waiting for key input (S1), if there is a key input (S2), check whether it is a power flag set (S3), if it is a power flag set, return to step S13, and if it is not a power flag set, apply a power-off key. Check (S4). Therefore, when the power-off key, the microprocessor 400 outputs a low (L) signal to the motor speed controller 600 (S15) to stop the driving of the motor (S16).

On the other hand, if the power-off key is not checked, the momentary action key is applied (S7). If the momentary action key is applied, a high (H) signal is output to the motor speed controller 600 (S8) to drive the motor (S9). If the application is checked (S10) and the key is off, a low signal is output to the motor speed controller 600 (S5) to stop the motor (S6).

On the other hand, if the momentary operation key is not set the power flag (S12) and thus outputs a high signal to the motor speed control unit 600 (S13) to drive the motor (S14). At this time, check whether the speed of the motor is 30 sec pass (S15) or return to step S14. If the 30 sec pass, a low signal is output to the motor speed controller 600 (S16) to stop the motor. (S17). If the speed of the motor is not 20 sec pass, the process returns to step S17. If the motor speed is 20 sec, it returns to the power flag set step S3.

As such, when an operation mode for pulverizing a specific material is selected, the driving signal output to the motor speed control unit 600 may be differently output at predetermined time intervals to increase or decrease the rotational speed of the motor.

According to the present invention operated as described above, the driving signal corresponding to the material or the purpose of use selected as a key input is output to the motor speed control unit to adjust the power level supplied to the motor to adjust the rotational speed of the motor, thereby crushing the material. It is to provide the effect to properly grind the material according to the purpose of use.
