With continued reference to fig. 2, the voltage detection circuit 12 is connected to a power supply 20. The voltage detection circuit 12 may be connected to either the neutral line N or the hot line L of the power supply 20. The voltage detection circuit 12 detects the voltage of the load 30 and outputs a corresponding voltage signal.
Fig. 4 is a circuit diagram of the voltage detection circuit 12. Referring to fig. 2 and 4, the voltage detection circuit 12 may include a second voltage division circuit 121, and one end of the second voltage division circuit 121 may be connected to one end of the power supply 20 and the other end may be grounded. In the illustrated embodiment, the voltage detection circuit 12 includes a terminal ACL, and the second voltage division circuit 121 may be connected to one end of the power supply 20 through the terminal ACL. The second voltage divider circuit 121 can be connected to the power line L of the power supply 20 via a terminal ACL.
The second voltage dividing circuit 121 may include a third voltage dividing resistor 1211 and a fourth voltage dividing resistor R7 connected in series, and the voltage detection port Uin of the main controller 13 may be connected between the third voltage dividing resistor 1211 and the fourth voltage dividing resistor R7. The voltage detection port Uin detects a voltage across the third voltage dividing resistor 1211 or the fourth voltage dividing resistor R7. In the illustrated embodiment, one end of the fourth voltage dividing resistor R7 is connected to the voltage detection port Uin, the other end is grounded, and the voltage detection port Uin detects the voltage across the fourth voltage dividing resistor R7. In the illustrated embodiment, the third voltage dividing resistor 1211 includes two resistors R4, R5 connected in series, and the fourth voltage dividing resistor R7 includes one resistor, in other embodiments, the third voltage dividing resistor 1211 may include one or more resistors connected in series, and the fourth voltage dividing resistor 1211 may include two or more resistors connected in series.
The voltage detection circuit 12 may include a current limiting resistor R6, wherein one end of the current limiting resistor R6 is connected between the third voltage dividing resistor 1211 and the fourth voltage dividing resistor R7, and the other end is connected to the voltage detection port Uin. The current limiting resistor R6 is used to limit the current and prevent the main controller 13 from being damaged by excessive current.
The voltage detection circuit 12 may include a diode D5, wherein the anode of the diode D5 is connected to one end of the power source 20, and the cathode is connected to the second voltage division circuit 121. In the illustrated embodiment, the anode of diode D5 is connected to power source 20 via terminal ACL.

The voltage detection circuit 12 may include a capacitor C2, wherein one end of the capacitor C2 is connected between the third voltage dividing resistor 1211 and the fourth voltage dividing resistor R7, and the other end is grounded. The capacitor C2 can filter out interference signals and improve the signal-to-noise ratio of the voltage signal detected by the voltage detection port Uin. In other embodiments, the voltage detection circuit 12 may not include the capacitor C2.
The main controller 13 collects the voltage signal output by the voltage detection circuit 12 through the voltage detection port, and may calculate the voltage of the load 30 according to the voltage signal. In the embodiment shown in fig. 3, the voltage signal output by the voltage detection circuit 12 includes the voltage across the fourth voltage dividing resistor R7, and the main controller 13 can calculate the voltage of the load 30 according to the voltage across the fourth voltage dividing resistor R7 by using the following formula (6):
wherein U is the voltage of the load, R4、R5、R7Respectively the resistances of the resistors R4, R5 and R7,
is the voltage across the fourth voltage divider resistor R7.
For the safety of the voltage detection port of the main controller 13, the voltage across the fourth voltage dividing resistor R7 should be made smaller than the safety voltage of the voltage detection port Uin. In designing the voltage detection circuit 12, the resistance values of the resistors R4, R5, and R7 may be determined according to the safe voltage of the voltage detection port Uin.
The main controller 13 collects an electrical signal of the current detection circuit 11 through the current detection port Iin, collects a voltage signal of the voltage detection circuit 12 through the voltage detection port Uin, and determines the working power of the load 30 according to the electrical signal and the voltage signal.
If the master controller 13 only detects the voltage of the load 30 or the current flowing through the load 30, it is also necessary to combine the resistance of the load 30 to determine the operating power of the load 30. Due to individual differences of different loads 30, the resistance of different loads 30 is not exactly the same size, which may reduce the accuracy of determining the operating power of different loads 30. In addition, if only the voltage of the load 30 or the current flowing through the load 30 is detected, the determined operating power of the load may also be inaccurate if the detected voltage or current is inaccurate, for example, the detected voltage is unstable due to the difference in the voltage waveform of the power grid.
In the embodiment of the present application, the main controller 13 determines the working power of the load according to the current flowing through the load and the voltage of the load, and the accuracy of determining the working power of the load can be improved compared with the determination of the working power of the load only according to the detected voltage of the load or the current flowing through the load. The main controller adjusts the working power of the load according to the determined current working power of the load and the set power of the load, so that the deviation between the working power of the load and the set power can be reduced, the service life of the load is prolonged, and the stability of the working state of the food processor 100 is improved. In addition, even if the voltage signal detected by the voltage detection circuit is different from the rated value of the power grid voltage due to the voltage waveform difference of the power grid, or the electric signal detected by the current detection circuit is unstable, because the main controller determines the working power of the load according to the electric signal and the voltage signal, the error between the determined working power of the load and the actual working power is small.
Fig. 5 is a flow chart illustrating the adjustment of the heating power of the heating element provided by the present application. Referring to fig. 5, the process of the main controller adjusting the heating power of the heating element may include the following steps 101 to 106.
In step 101, the food processor starts operating.
In step 102, the heating element heats.
In step 103, the actual heating power of the heating element is compared with the set heating power. If the actual heating power is less than the set heating power, executing step 104; if the actual heating power is greater than the set heating power, executing step 105; if the actual heating power is equal to the set heating power, step 106 is executed.
In step 104, the heating power is increased. When actual heating power is less than heating power, increase heating power, can avoid heating power too little and lead to the problem that the edible material in the cooking cup boils not thoroughly.
In step 105, the heating power is reduced. When actual heating power is greater than heating power, reduce heating power, can avoid heating power too big and lead to the problem that the edible material in the cooking cup spills over the cooking cup because of heating excessive boiling.
In step 106, the heating element continues to heat.
Fig. 6 is a flowchart illustrating the adjustment of the stirring power of the motor according to the present application. Referring to fig. 6, the process of the main controller adjusting the stirring power of the motor may include the following steps 201 to 206.
In step 201, the food processor starts operating.
In step 202, the motor is operated.
In step 203, the actual whipping power of the motor is compared with the set stirring power. If the actual agitating power is less than the set agitating power, executing step 204; if the actual whipping power is greater than the set whipping power, go to step 205; if the actual whipping power is equal to the set whipping power, step 206 is executed.
In step 204, the whipping power is increased. When the actual stirring power is smaller than the set stirring power, the stirring power is increased, so that the problem that the food materials in the cooking cup cannot be stirred and smashed due to too small stirring power can be avoided.
In step 205, the whipping power is reduced. When the actual stirring power is larger than the set stirring power, the stirring power is reduced, and the problem that the food materials in the cooking cup overflow the cooking cup due to the fact that the stirring speed is too high due to the fact that the stirring power is too large can be avoided.
In step 206, the motor continues to run.
