[0027]

[0028] like Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, the electronic display screen 6, the power switch 7 and the voice broadcast speaker 9 are arranged on the outer surface of the dough mixer, which is convenient for the user to operate, to view the information on the electronic display screen, and to listen to the voice broadcast.

[0029] like Figure 2 、 Figure 3 、 Figure 4As shown, in this embodiment, the control module 10 includes a microprocessor 101, a Hall effect element 102, a temperature sensor 103, an electronic display screen drive circuit 104, a voice announcement drive circuit 105, and a motor operating condition control circuit 106. The Hall effect element 102 is mounted on the stator structure of the drive motor 5 to obtain the rotor speed signal of the drive motor 5 and the current signal passing through the drive motor 5. The Hall effect element is a magnetic sensor based on the Hall effect. They can detect magnetic fields and their changes and are suitable for various magnetic field-related applications. Hall effect elements have many advantages, including a strong structure, small size, light weight, long life, easy installation, low power consumption, high frequency, vibration resistance, and resistance to contamination or corrosion from dust, oil, water vapor, salt spray, etc. Hall effect elements can be divided into direct applications and indirect applications based on the nature of the object being detected. The former directly detects the magnetic field or magnetic properties of the object being tested, while the latter detects the artificially set magnetic field on the object being tested, using this magnetic field as the carrier of the detected information. Through it, many non-electrical and non-magnetic physical quantities such as force, torque, pressure, stress, position, displacement, speed, acceleration, angle, angular velocity, number of revolutions, rotational speed, and the time when the working state changes are converted into electrical quantities for detection and control.

[0030] like Figure 2 、 Figure 3 、 Figure 4 As shown, in this embodiment, the Hall element 102 obtains the speed signal of the rotor of the drive motor 5, which is converted by the microprocessor 101 and compared with a preset threshold value. When the speed signal exceeds / falls below the preset threshold, the microprocessor 101 sends a fault instruction to the electronic display screen 6 through the electronic display screen drive circuit 104. The microprocessor 101 sends a voice prompt to the voice broadcast speaker 9 through the voice broadcast drive circuit 105, and simultaneously sends an instruction to the motor working condition control circuit 106 to start the countdown and prepare to stop the operation of the drive motor 5. In this case, the drive motor 5 is stalled, the voice broadcast speaker 9 emits a motor stall prompt voice, and the electronic display screen 6 displays the fault code E01. After receiving the instruction, the user debugs and maintains the dough mixer and resumes operation after resolving the fault. The utility model provides a dough mixer with a working status voice broadcast and fault reminder function. The dough mixer with a working status voice broadcast and fault reminder function integrates multiple functions such as motor control, working time display, working status display, overtemperature alarm and protection, and voice broadcast, and has the characteristics of convenience, intuitiveness, intelligence, and safety.

[0031] like Figure 2 、 Figure 3 、 Figure 4As shown, in this embodiment, the Hall element 102 obtains the current signal passing through the drive motor 5, which is converted by the microprocessor 101 and compared with a preset threshold value. When the current signal exceeds / is lower than the preset threshold, the microprocessor 101 sends a fault instruction to the electronic display screen 6 through the electronic display screen drive circuit 104. The microprocessor 101 sends a voice prompt to the voice broadcast speaker 9 through the voice broadcast drive circuit 105, and at the same time sends an instruction to start the countdown and prepare to stop the operation of the drive motor 5 to the motor working condition control circuit 106. In this case, the current of the drive motor 5 detects the load, and the speed signal converted by the microprocessor 101 is compared with the preset threshold value. When the current signal exceeds the preset threshold, the dough weight in the mixing barrel is overloaded, the voice broadcast speaker 9 sends a prompt voice of motor overload, and the electronic display screen 6 displays the fault code E02. After receiving the instruction, the user reduces the amount of dough in the mixing barrel and resumes operation after resolving the fault. The utility model provides a dough mixer with voice broadcast of working status and fault reminder function. The dough mixer with voice broadcast of working status and fault reminder function integrates multiple functions such as motor control, working time display, working status display, over-temperature alarm and protection, voice broadcast, etc., and is convenient, intuitive, intelligent and safe.
