Problems solved by technology

[0003] However, since the rotor of the single-phase series-excited motor always maintains a constant direction of rotation, the controllable phase-shift voltage regulation is usually used for the adjustment of the speed of the single-phase series-excited motor, and the trigger voltage of the thyristor lags behind the input voltage to realize the shift of the input voltage. phase triggering to adjust the trigger voltage, thereby adjusting the speed of the single-phase series-excited motor. Quickly realize the braking function, that is, the motor stops quickly. However, during the working process of the food processor, if the user suddenly lifts the stirring cup to disconnect the micro switch, the cup lid is suddenly opened, or the current value of the motor is too large, etc. , for the sake of safety, it is necessary to realize the rapid stop of the motor to avoid accidentally injuring the user

Embodiment 1

[0044] combine Figure 1 to Figure 5 As shown, the first embodiment of the present invention provides a method for controlling a food processing machine. The food processing machine includes a brushless motor module for stirring and pulverizing materials, a control unit for controlling the brushless motor module, and a Hall detection module. The control method of the processing machine includes the following steps:

[0045] Step S101: the control unit obtains the speed of the brushless motor in the brushless motor module, and when the speed of the brushless motor is not greater than the preset value T1, the brushless motor is controlled by using a square wave; when the speed of the brushless motor is greater than the preset value At T1, a sine wave is used to control the brushless motor.

[0046] Such as Figure 3 to Figure 5 As shown, when the food processor is started, a large torque is required to provide a large power to start, so this embodiment adopts square wave contr...

Embodiment 2

[0052] In this embodiment, the brake protection module includes a lid opening detection module, and the food processor detects the opening state of the lid of the stirring cup through the lid opening detection module, wherein the opening state of the lid of the stirring cup includes an open state and a closed state. Such as Figure 6 As shown, the control method of the food processing machine includes the following steps:

[0053] Step S201: The control unit detects the opening state of the lid of the blender cup, and the opening state includes an open state and a closed state.

[0054] When the food processor is working, the lid of the blender cup may be open due to improper installation or human error. The control unit in the embodiment of the present application detects the opening state of the lid of the stirring cup during the working process of the food processor through the lid opening detection module, and performs corresponding operations according to the opening sta...

Embodiment 3

[0058] In this embodiment, the brake protection module includes a zero-crossing detection module, and the food processing machine obtains the power-on state of the food processing machine through the zero-crossing detection module, and the power-on state includes an on state and an off state, such as Figure 7 As shown, the control method of the food processing machine includes the following steps:

[0059] Step S301: the control unit detects the power-on state of the food processor, and the power-on state includes an on state and an off state.

[0060] Such as Figure 8 As shown, the zero-crossing detection module includes an input terminal and an output terminal, and the input terminal and the output terminal are isolated by an optocoupler. There is a phototransistor for receiving the signal from the light-emitting diode U1. When the food processor is working, when the mains power is in the positive half cycle, the optocoupler light-emitting diode U1 is turned on, the photot...

Abstract

The invention discloses a food processor and a control method thereof. The food processor comprises a base, a brushless motor module arranged in the base, a control unit for controlling the brushlessmotor module, and a stirring cup arranged on the base, the stirring cup comprises a cup body and a cup cover installed on the cup body, and the control method comprises the steps that the control unitobtains a brake protection signal and sends a brake instruction according to the brake protection signal; and the brushless motor module executes protective brake shutdown according to the brake instruction. The brushless motor can stop rotating quickly, so that the effect of quick braking of the food processor is achieved, and the use safety of a user is improved.

Description

technical field [0001] The invention relates to the technical field of household appliances, in particular to a food processing machine and a control method thereof. Background technique [0002] Food processors are household appliances with a high selection rate for modern home health care and health preservation. Existing food processing machines mostly use single-phase series-excited motors to drive the pulverizer assembly to stir the food materials, so as to realize the production of foods such as soybean milk and rice paste. [0003] However, since the rotor of the single-phase series-excited motor always maintains a constant direction of rotation, the controllable phase-shift voltage regulation is usually used for the adjustment of the speed of the single-phase series-excited motor, and the trigger voltage of the thyristor lags behind the input voltage to realize the shift of the input voltage. phase triggering to adjust the trigger voltage, thereby adjusting the spee...
