Description

Technical Field

[0001] This utility model relates to the field of bread machines, and in particular to a motor control structure for a bread machine capable of making ice cream. Background Technology

[0002] To enrich the functionality of bread makers, some manufacturers have developed bread makers with ice cream-making capabilities (such as Chinese patent CN204120858U). These bread makers have a bread pan and an ice cream pan with a speed reduction mechanism. To make ice cream, the ice cream pan is first frozen to lower its temperature. Then, ice cream ingredients are placed into the ice cream pan, and the speed reduction mechanism is connected to the bread maker's motor. The motor then rotates, driving the ice cream pan at the required speed through the speed reduction mechanism, thus churning the ice cream ingredients and gradually transforming them into ice cream. However, existing bread makers with this ice cream-making function require a speed reduction mechanism in the ice cream pan, resulting in a relatively large size and high cost.

[0003] In view of the above problems, it is necessary to study a motor control structure for a bread machine that can make ice cream, which can directly use the bread pan to make ice cream, thus helping to reduce costs. Utility Model Content

[0004] The purpose of this invention is to provide a motor control structure for a bread maker that can make ice cream, which can directly use the bread pan to make ice cream.

[0005] To achieve the above objectives, the solution of this utility model is: A motor control structure for a bread maker capable of making ice cream includes a microcontroller U1, a motor M1, a thyristor TR1, a transistor Q1, resistors R1 and R2, a capacitor C1, and a power terminal J1 for connecting to AC power. One output terminal of the microcontroller U1 is connected to the base of the transistor Q1 through resistor R1. The emitter of the transistor Q1 is grounded. The collector of the transistor Q1 is connected to the gate (G) terminal of the thyristor TR1 through resistor R2. The T1 terminal of the thyristor TR1 is connected to the N terminal of the power terminal J1. The T2 terminal of the thyristor TR1 and the first terminal of the capacitor C1 are connected to the first terminal of the motor M1. The second terminal of the motor M1 is connected to the L terminal of the power terminal J1. The second terminal of the capacitor C1 is grounded.

[0006] The motor control structure of the bread maker that can make ice cream also includes a fuse F1, and the T2 terminal of the thyristor TR1 is connected to the first end of the motor M1 through the fuse F1.

[0007] The motor control structure of the bread maker that can make ice cream also includes a fuse F2, and the second end of the motor M1 is connected to the L end of the power terminal J1 through the fuse F2.

[0008] The motor control structure of the bread maker that can make ice cream also includes a fuse F3, and the T1 terminal of the thyristor TR1 is connected to the N terminal of the power supply terminal J1 through the fuse F3.

[0009] The motor control structure of the bread maker that can make ice cream also includes a capacitor C2, the two ends of which are connected to the T1 terminal and the G terminal of the thyristor TR1, respectively.

[0010] With the above solution, when a user uses the bread maker of this invention to make ice cream, the user first freezes the bread pan, then puts the ice cream ingredients into the bread pan, connects the bread pan to the motor M1, and then sends an ice cream making command to the microcontroller U1. The microcontroller U1 outputs a PWM signal to the transistor Q1 to control the transistor Q1 to turn on and off at regular intervals, which in turn controls the thyristor TR1 to turn on and off at regular intervals. This causes the motor M1 to rotate the bread pan at a speed suitable for stirring the ice cream ingredients, so that the ice cream ingredients in the bread pan are stirred and gradually turn into ice cream. The speed of the motor M1 can be adjusted by setting the duty cycle of the PWM signal output by the microcontroller U1 to the transistor Q1, so that the motor M1 drives the bread pan to rotate at a speed suitable for stirring the ice cream ingredients.

[0011] As can be seen from the above, this utility model can directly use bread buckets to make ice cream, thus eliminating the need for ice cream buckets with deceleration mechanisms, which helps to reduce costs. Attached Figure Description

The collector of the transistor Q1 is connected to the gate (G) terminal of the thyristor TR1 through resistor R2. The T1 terminal of the thyristor TR1 is connected to the N terminal of the power terminal J1. The T2 terminal of the thyristor TR1 and the first terminal of the capacitor C1 are connected to the first terminal of the motor M1. The second terminal of the motor M1 is connected to the L terminal of the power terminal J1. The second terminal of the capacitor C1 is grounded.

The microcontroller U1 outputs a PWM signal to the transistor Q1 to control the transistor Q1 to turn on and off at regular intervals, which in turn controls the thyristor TR1 to turn on and off at regular intervals. This causes the motor M1 to rotate the bread pan at a speed suitable for stirring the ice cream ingredients, so that the ice cream ingredients in the bread pan are stirred and gradually turn into ice cream. The speed of the motor M1 can be adjusted by setting the duty cycle of the PWM signal output by the microcontroller U1 to the transistor Q1, so that the motor M1 drives the bread pan to rotate at a speed suitable for stirring the ice cream ingredients.

The two ends of the capacitor C2 are respectively connected to the T1 terminal and the G terminal of the thyristor TR1, and the capacitor C2 can play a noise reduction role.
