[0053] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0054] The technical solution of this application is mainly applied to cooking equipment with mixing and blending functions. Cooking equipment typically generates considerable noise during mixing. To reduce noise, this application proposes a cooking equipment control method.

[0055] like Figure 1The diagram shows an example of a cooking device, such as a food processor, which includes a cup body 101 and a base 102. A blade assembly 103 can be installed at the bottom of the cup body 101, and a motor 104 can be disposed in the base 102. When the cup body 101 is placed in the base 102, the output shaft of the motor 104 can drive the blade assembly 103 to rotate.

[0056] Figure 2 This is a flowchart illustrating a cooking device control method according to an exemplary embodiment. The execution subject of this method can be a processor in the cooking device or the cooking device itself; for example... Figure 2 As shown, the method includes the following steps 201-203:

[0057] In step 201, the predetermined speed of the motor corresponding to the current function setting of the cooking device is obtained.

[0058] Cooking equipment typically has multiple functions, capable of making various foods such as soy milk, rice porridge, fruit puree, fruit and vegetable juice, soup, smoothies, and minced meat. Users select different function levels using buttons or a touch panel on the equipment. When the cooking equipment operates at different function levels, its motor is set with different preset speeds to achieve different functions. Some function levels require higher motor speeds to utilize the high-speed rotation of the blades to mince ingredients, such as the soy milk and minced meat functions. Other function levels only require lower motor speeds, such as the fruit and vegetable juice function. The correspondence between function levels and preset motor speeds can be illustrated in Table 1 below, where r / min is the unit of motor speed: revolutions per second.

[0059] Table 1

[0060] Function level 1 X1 r / min Functional level 2 X2 r / min Functional level 3 X3 r / min Functional level 4 X4 r / min

[0061] In step 202, the target conduction angle of the thyristor used to control the motor speed is determined, including steps A1-A3:

[0062] Step A1: Adjust the conduction angle of the thyristor so that the actual speed of the motor is equal to the predetermined speed.

[0063] like Figure 3The diagram shows a circuit diagram of the motor control for an exemplary cooking device. The switch control module 302 and the motor 303 are connected in series in the circuit, with L representing the live wire and N representing the neutral wire. A chip 301 is also connected in the circuit diagram to control the switch control module 302, thereby controlling the motor 303. In this embodiment, a silicon controlled rectifier (SCR) can be used in the switch control module 302 to control the motor speed. SCR speed regulation changes the waveform of the motor terminal voltage by altering the conduction angle of the SCR, thus changing the effective value of the motor terminal voltage and achieving speed regulation. In one embodiment of this application, the conduction angle of the SCR is adjusted by chopping control of the SCR.

[0064] In one embodiment of this application, the motor speed can be controlled first using a PID (proportional, integral, derivative) feedback control algorithm. The PID feedback control algorithm dynamically adjusts the conduction angle of the thyristor, thereby ultimately making the actual motor speed equal to the predetermined speed. The principle of the PID feedback control algorithm is as follows: after each adjustment of the thyristor's conduction angle, the feedback motor speed is obtained to determine whether the actual motor speed equals the predetermined speed. If not, the conduction angle of the thyristor is continuously adjusted. This process is repeated until the actual motor speed equals the predetermined speed by frequently adjusting the thyristor's conduction angle and using the feedback motor speed.

[0065] In one embodiment of this application, the motor speed can be obtained using a Hall sensor.

[0066] Step A2: Obtain the conduction angle of the thyristor when the actual speed of the motor is equal to the predetermined speed N times, where N is a positive integer greater than 1.

[0067] In the above embodiment, during the process of controlling the motor speed to equal the predetermined speed using the PID algorithm feedback control algorithm, the actual speed of the motor continuously changes. For example, if the predetermined speed is 10000 r / min, it will fluctuate between 9200 r / min and 10800 r / min due to factors such as water flow disturbance. During this fluctuation, the PID algorithm dynamically and frequently adjusts the conduction angle of the thyristor, meaning the conduction pin also changes continuously, so that the actual speed of the motor equals the predetermined speed. Each time the actual speed of the motor equals the predetermined speed, the conduction angle of the thyristor is recorded. By repeating this step at least N times, N conduction angles of the thyristor can be obtained.

[0068] Step A3: Determine the target conduction angle of the thyristor based on the obtained conduction angles of the N thyristors.

[0069] When the motor speed is controlled to equal the predetermined speed using the PID feedback control algorithm, after obtaining the conduction angles of N thyristors, since all of these N thyristor conduction angles can make the motor speed reach the predetermined speed, a relatively accurate conduction angle can be determined from these N thyristor conduction angles, which is the target conduction angle of the thyristor.

[0070] In step 203, the thyristor is adjusted to control the motor operation at the target conduction angle.

[0071] Once the target conduction angle is determined based on the conduction angles of the N thyristors, the PID algorithm can be turned off, and the motor can be controlled with a fixed target conduction pin. At this time, the motor speed fluctuation can be kept between 9600 r / min and 10400 r / min, with relatively small speed fluctuation.

[0072] The technical solution proposed in this application, based on existing hardware, first controls the motor speed by frequently changing the conduction angle of the thyristor to make the motor reach a predetermined speed. During this process, N conduction angles of the thyristor are obtained, thereby determining a relatively accurate target conduction angle. Then, the thyristor controls the motor with this fixed target conduction angle, which can better stabilize the speed, effectively reduce the collision between water and the cup wall caused by speed fluctuations, reduce the vibration of the whole machine, and thus achieve the effect of reducing noise without increasing the cost of other hardware.

[0073] like Figure 4 The following is an example Figure 3 The diagram shows the circuit of the switch control module. The switch control module uses a Silicon Controlled Rectifier (SCR) to control the motor speed. SCR speed regulation works by changing the conduction angle of the SCR to alter the waveform of the motor terminal voltage, thereby changing the effective value of the motor terminal voltage and achieving speed regulation. For example, when the SCR conduction angle is 180 degrees, the motor terminal voltage waveform is a sine wave, i.e., fully conductive; when the SCR conduction angle is less than 180 degrees, i.e., not fully conductive, the effective voltage value decreases. The smaller the conduction angle, the fewer conductive states, resulting in a smaller effective voltage value and a lower motor speed.

[0074] exist Figure 4The circuit diagram shown includes resistors R401, R402, R403, R404, and R405; capacitors C401, C402, and C403; a silicon controlled rectifier (SCR) SCR201; and transistor Q1. C401 and R403 are connected in parallel; C402 and R404 are connected in parallel; and R405 and C403 are connected in series. The Motor terminal of resistor R401 is connected to the chip's port. N1 is connected to the neutral wire of the high-voltage power supply. The Motor terminal is connected to the motor's neutral wire, and the motor's live wire is connected to the high-voltage power supply's live wire. The high and low levels at the Motor terminal control the conduction and cutoff of Q1, thereby controlling the conduction and cutoff of the SCR201. When Q1 is on, N1 and the Motor terminal are short-circuited, and the motor operates. Thus, the chip adjusts the conduction angle of the SCR201 by controlling the on and off states of Q1.

[0075] In one embodiment of this application, determining the target conduction angle of a thyristor based on the obtained conduction angles of N thyristors may include: calculating the target conduction angle using a median averaging algorithm.

[0076] When the motor speed is X r / min, the thyristor conduction angles, arranged from largest to smallest, are: a1, a2, a3...a n Where n is an integer between 1 and N, the target conduction angle Y is calculated according to the following formula:

[0077] In one embodiment of this application, based on the above embodiments, after adjusting the thyristor to control the motor operation at the target conduction angle, voltage fluctuations and the state of food grinding will change the rotational speed at the fixed conduction angle. Therefore, the conduction angle needs to be readjusted to maintain the fixed rotational speed of the motor. Thus, continuous monitoring of the motor speed is also required. Figure 5 As shown, steps 204-205 are also included:

[0078] In step 204, the current speed of the motor is acquired in real time;

[0079] In step 205, if the difference between the current speed of the motor and the predetermined speed is outside the preset range, the step of determining the target conduction angle is repeated.

[0080] In this embodiment, after controlling the motor speed with the calculated target conduction angle, the actual speed of the motor is also monitored in real time to readjust the conduction angle and maintain the fixed speed of the motor.

[0081] Figure 6This is a flowchart illustrating a cooking device control method according to an exemplary embodiment. The device executing this method can be a cooking appliance such as a food processor, soy milk maker, high-speed blender, or stir-fry machine equipped with a motor and stirring components. Figure 6 As shown, the method includes the following steps 601-603:

[0082] Step 601: Obtain the predetermined speed X1 r / min of the motor corresponding to the current function setting of the cooking device.

[0083] When the cooking equipment is turned on, the user can select a function level via the panel or knob. Based on the pre-set correspondence between the function level and the motor's preset speed, the user can obtain the preset speed of the motor corresponding to the current function level.

[0084] Step 602: Wait for the motor to work for more than m seconds, where m is a positive integer.

[0085] The purpose of this step is to prevent the PID algorithm from being implemented when the motor starts to accelerate, and to implement it only when the speed approaches the set speed. This waiting time can be set based on the time it takes for the motor to reach the set speed.

[0086] Step 603: Control the motor speed through PID feedback control algorithm. During the PID process, obtain the conduction angle of the thyristor when the actual motor speed is equal to the predetermined speed N times. Based on the obtained N conduction angles of the thyristor, calculate the target conduction angle according to the median average algorithm.

[0087] Step 604: Turn off the PID feedback control algorithm and control the motor speed with the target conduction angle.

[0088] Step 605: Obtain the current speed of the motor in real time.

[0089] Step 606: Determine whether the difference between the current speed of the motor and the predetermined speed is within a preset range. If yes, proceed to step 605; otherwise, proceed to step 603.

[0090] The preset range is, for example, the current rotational speed of the electrode between X1-500 r / min and X1+500 r / min.
