第1圖是根據本發明一實施例的食物料理機的烹飪控制方法的流程圖。其中，如第2圖所示，食物料理機包括攪拌件、驅動攪拌件的電機和驅動電機的矽控模組（圖中未具體示出），電機的轉子上設有磁環；如第1圖所示，烹飪控制方法包括以下步驟： S1，檢測輸入至電機的交流電AC的零交叉訊號。 S2，根據零交叉訊號獲取交流電AC的零交叉點，並在零交叉點延遲第一預設時間T1後輸出開啟脈衝訊號至矽控模組、且每隔第二預設時間T2輸出一開啟脈衝訊號至矽控模組，以在食物料理機進行烹飪食物時通過矽控模組驅動電機運行，其中，第二預設時間T2為交流電AC的半個週期。 S3，通過霍爾感測器檢測磁環提供的磁場變換訊號以輸出交變的電位準訊號，並根據交變的電位準訊號採用週期測速法獲取電機的轉速V。 在本發明的實施例中，磁環的級數為偶數且大於等於12級。 S4，根據電機的轉速V對第一預設時間進行調節以控制電機低速恆速運行，以在食物料理機的烹飪過程中驅動攪拌件對所烹飪食物進行攪拌。Fig. 1 is a flow chart showing a cooking control method of a food processor according to an embodiment of the present invention. Wherein, as shown in FIG. 2, the food cooking machine comprises a stirring member, a motor for driving the stirring member and a control module for driving the motor (not specifically shown), and the rotor of the motor is provided with a magnetic ring; As shown in the figure, the cooking control method comprises the following steps: S1, detecting a zero cross signal of the alternating current AC input to the motor. S2, obtaining a zero crossing point of the alternating current AC according to the zero cross signal, and outputting the opening pulse signal to the monitoring module after delaying the first preset time T1 at the zero crossing point, and outputting an opening pulse every second preset time T2 The signal is sent to the control module to drive the motor to run through the control module when cooking the food, wherein the second preset time T2 is a half cycle of the AC AC. S3, the magnetic field conversion signal provided by the magnetic ring is detected by the Hall sensor to output the alternating potential potential signal, and the motor speed V is obtained by the periodic speed measurement method according to the alternating potential signal. In an embodiment of the invention, the number of stages of the magnetic ring is even and greater than or equal to 12. S4, adjusting the first preset time according to the rotation speed V of the motor to control the low speed and constant speed operation of the motor to drive the stirring member to stir the cooked food during the cooking process of the food processor.

其中，在本發明的實施例中，食物料理機烹飪的食物可以為粥，電機的運行轉速V可以為200轉/分至500轉/分。In the embodiment of the present invention, the food cooked by the food cooking machine may be porridge, and the running speed V of the motor may be 200 rpm to 500 rpm.

具體地，如第3圖和第4圖所示，電機上電後，INT檢測埠會產生電位準變化，交流電AC經過Q1會產生50Hz/60Hz左右的方波訊號即零交叉訊號。根據零交叉訊號獲取交流電AC的零交叉點，並在零交叉點延遲第一預設時間T1後，採用PWM（Pulse Width Modulation，脈衝寬度調製）技術，輸出開啟脈衝訊號至矽控模組，矽控模組在接收到開啟脈衝訊號後導通，從而使電機工作，並且每隔T2時間輸出開啟脈衝訊號至矽控模組，其中，第二預設時間T2等於交流電AC週期的1/2。T2是定值，通過改變第一預設時間T1的大小，即可改變矽控模組的導通時間，從而改變電機的轉速V。Specifically, as shown in FIG. 3 and FIG. 4, after the motor is powered on, the INT detection 埠 will produce a potential change, and the AC AC will generate a square wave signal of 50 Hz/60 Hz or zero cross signal after passing through Q1. Obtain the zero crossing point of the AC AC according to the zero-crossing signal, and after the first preset time T1 is delayed at the zero-crossing point, use PWM (Pulse Width Modulation) technology to output the pulse signal to the control module. The control module is turned on after receiving the turn-on pulse signal, so that the motor operates, and the pulse signal is output to the control module every T2 time, wherein the second preset time T2 is equal to 1/2 of the AC AC cycle. T2 is a fixed value. By changing the size of the first preset time T1, the conduction time of the control module can be changed, thereby changing the rotational speed V of the motor.

如第2圖所示，電機包括轉子和定子，磁環固定在轉子上，霍爾感測器固定在電機的外殼上，電機通電時，其線圈會產生交變磁場，轉子因交變的磁場的動力牽引進行旋轉。磁環由有磁性和無磁性的塊狀組成，當有磁性的一面靠近霍爾感測器時，可以改變霍爾感測器的電位準訊號，當無磁性的一面靠近霍爾感測器時，霍爾感測器恢復初始的電位準訊號。因此，如第3圖所示，當磁環轉動時，會引起靠近它的霍爾感測器產生交變的電位準訊號，即埠SENSOR會產生交變的電位準訊號。在食物料理機執行煮粥程式時，根據交變的電位準訊號採用週期測速法可以計算出電機的轉速V。根據計算出的電機的轉速V，通過改變第一預設時間T1的大小控制電機低速恆速運行，以使攪拌件對烹飪食物進行低速攪拌，使所烹飪食物受熱均勻。由此，該方法通過改變電機矽控模組的導通時間可以使電機低速恆速運行，從而可以在烹飪過程中對食物進行攪拌，防止食物料理機出現糊底現象。As shown in Fig. 2, the motor includes a rotor and a stator. The magnetic ring is fixed on the rotor, and the Hall sensor is fixed on the outer casing of the motor. When the motor is energized, the coil generates an alternating magnetic field, and the rotor is subjected to an alternating magnetic field. The power is pulled to rotate. The magnetic ring consists of a magnetic and non-magnetic block. When the magnetic side is close to the Hall sensor, the Hall sensor's potential signal can be changed. When the non-magnetic side is close to the Hall sensor. The Hall sensor restores the initial potential signal. Therefore, as shown in Fig. 3, when the magnetic ring rotates, it causes the Hall sensor close to it to generate an alternating potential signal, that is, 埠SENSOR generates an alternating potential signal. When the porridge program is executed in the food processor, the motor speed V can be calculated according to the alternating potential signal. According to the calculated rotation speed V of the motor, the motor is controlled to operate at a low speed and a constant speed by changing the magnitude of the first preset time T1, so that the stirring member stirs the cooking food at a low speed to uniformly heat the cooked food. Therefore, the method can make the motor run at a low speed and a constant speed by changing the conduction time of the motor control module, so that the food can be stirred during the cooking process to prevent the bottom of the food cooking machine.

進一步，如第4圖所示，在零交叉點訊號的上升邊緣到來時延遲第一預設時間T1後輸出開啟脈衝訊號至矽控模組。Further, as shown in FIG. 4, after the rising edge of the zero-crossing signal arrives, the first preset time T1 is delayed and the open pulse signal is output to the control module.

可以理解的是，如第3圖所示，Q1存在導通電壓VT，當A點的電壓大於等於導通電壓VT時，Q1導通，當A點的電壓小於導通電壓VT時，Q1截止。所以零交叉訊號的電壓零交叉點不是交流電AC真正的零交叉點，存在Δt1時間的延遲。因此，如第4圖所示，在零交叉點訊號的上升邊緣到來時延遲第一預設時間T1後，採用PWM技術，輸出開啟脈衝訊號至矽控模組，矽控模組在接收到開啟脈衝訊號後導通，從而使電機工作，並且每隔T2時間輸出開啟脈衝訊號至矽控模組，其中，第二預設時間T2等於交流電AC週期的1/2。It can be understood that, as shown in FIG. 3, Q1 has a turn-on voltage VT. When the voltage at point A is greater than or equal to the turn-on voltage VT, Q1 is turned on. When the voltage at point A is less than the turn-on voltage VT, Q1 is turned off. Therefore, the zero-crossing point of the zero-crossing signal is not the true zero-crossing point of the AC AC, and there is a delay of Δt1 time. Therefore, as shown in FIG. 4, after the first preset time T1 is delayed when the rising edge of the zero-crossing signal arrives, the PWM signal is used to output the pulse signal to the control module, and the control module is turned on. After the pulse signal is turned on, the motor is operated, and the pulse signal is turned on to the control module every T2 time, wherein the second preset time T2 is equal to 1/2 of the AC power cycle.

根據本發明的一實施例，如第5圖所示，根據電機的轉速V對第一預設時間T1進行調節以控制電機低速恆速運行，可以包括： S401，判斷電機的轉速V是否大於目標轉速Vset 。其中，目標轉速Vset 可以根據實際情況進行預設。 S402，如果電機的轉速V大於目標轉速Vset ，則增大第一預設時間T1，通過降低矽控模組的導通時間以降低電機的轉速V，直至電機的轉速V等於目標轉速Vset 。 S403，如果電機的轉速V小於目標轉速Vset ，則減小第一預設時間T1，通過增大矽控模組的導通時間以提高電機的轉速V，直至電機的轉速V等於目標轉速Vset 。According to an embodiment of the present invention, as shown in FIG. 5, adjusting the first preset time T1 according to the rotational speed V of the motor to control the low speed and constant speed operation of the motor may include: S401: determining whether the rotational speed V of the motor is greater than the target Speed V set . The target speed V set can be preset according to actual conditions. S402, if the rotational speed V of the motor is greater than the target rotational speed Vset , increase the first preset time T1, and reduce the rotational speed V of the motor by lowering the conduction time of the control module until the rotational speed V of the motor is equal to the target rotational speed Vset . S403, if the rotational speed V of the motor is less than the target rotational speed Vset , the first preset time T1 is decreased, and the rotational speed V of the motor is increased by increasing the conduction time of the control module until the rotational speed V of the motor is equal to the target rotational speed Vset. .

具體地，在根據週期測速法計算出電機的轉速V後，判斷V是否大於Vset ，如果V＞Vset ，說明此時電機的轉速V較高，可以通過逐漸增大第一預設時間T1，降低矽控模組的導通時間，從而降低電機的轉速V，直至V=Vset 。如果V＜Vset ，說明此時電機的轉速V較低，可以通過逐漸降低第一預設時間T1，增大矽控模組的導通時間，從而增大電機的轉速V，直至V=Vset 。而如果V=Vset ，第一預設時間T1保持在當前大小不變。Vset 一般設置為低速，例如可以為200轉/分至500轉/分，以使電機帶動攪拌件進行低速攪拌。Specifically, after calculating the rotational speed V of the motor according to the periodic speed measurement method, it is determined whether V is greater than V set , and if V>V set , it indicates that the rotational speed V of the motor is high at this time, and the first preset time T1 can be gradually increased. , reduce the conduction time of the control module, thereby reducing the motor speed V until V = V set . If V<V set , it means that the motor speed V is low at this time, and the first preset time T1 can be gradually decreased to increase the conduction time of the control module, thereby increasing the motor speed V until V=V set . And if V=V set , the first preset time T1 remains unchanged at the current size. The V set is generally set to a low speed, for example, 200 rpm to 500 rpm, so that the motor drives the stirring member to perform low speed stirring.

在本發明的實施例中，根據交變的電位準訊號採用週期測速法獲取電機的轉速V，包括：通過計時器對交變的電位準訊號中兩個脈衝產生的間隔寬度Tx進行測量；根據兩個脈衝產生的間隔寬度Tx以及磁環轉動一周霍爾感測器輸出的交變的電位準訊號所對應的脈衝個數N計算電機的轉速V。In the embodiment of the present invention, the rotational speed V of the motor is obtained by using the periodic velocity measurement method according to the alternating potential signal, including: measuring, by using a timer, the interval width Tx generated by the two pulses in the alternating potential signal; The interval width Tx generated by the two pulses and the number N of pulses corresponding to the alternating potential signal output from the Hall sensor at one revolution of the magnetic ring calculate the rotational speed V of the motor.

具體而言，如第6圖所示，電機的轉速V=60/PTx，其中，Tx為交變的電位準訊號中兩個脈衝產生的間隔寬度，P為電機的極對數，由於P為已知量，所示通過檢測出Tx即可計算出電機的轉速V。Tx可以通過計時器和計數器測得，可以根據交變的電位準訊號啟動計時器，同時控制脈衝發生器在Tx內產生基準時鐘脈衝S，計數器對Tx內產生的基準時鐘脈衝S的個數N進行計數，其中，基準時鐘脈衝S的頻率為fc，根據N和fc即可計算出Tx，Tx=N/fc。因此，根據以下公式（1）即可計算出電機的轉速V。Specifically, as shown in Fig. 6, the rotational speed of the motor is V=60/PTx, where Tx is the interval width of the two pulses in the alternating potential signal, and P is the pole number of the motor, since P is already Knowing the quantity, the motor speed V can be calculated by detecting Tx. Tx can be measured by a timer and a counter, and the timer can be started according to the alternating potential signal, and the control pulse generator generates the reference clock pulse S in Tx, and the number of reference clock pulses S generated by the counter pair Tx is N. Counting is performed, wherein the frequency of the reference clock pulse S is fc, and Tx, Tx=N/fc can be calculated from N and fc. Therefore, the rotational speed V of the motor can be calculated according to the following formula (1).

V=60fc/PN， （1）V=60fc/PN, (1)

其中，V為電機的轉速，P為電機的極對數，fc為基準時鐘脈衝S的頻率，N為Tx內產生的基準時鐘脈衝S的個數。Where V is the rotational speed of the motor, P is the number of pole pairs of the motor, fc is the frequency of the reference clock pulse S, and N is the number of reference clock pulses S generated in Tx.

可以理解的是，由於存在測量誤差，誤差主要有兩方面，一是交變的電位準訊號中兩個脈衝的上升邊緣觸發時間可能不一致；二是計數和計時器起始和關閉可能不同步。因此，為提高測量精度，減少測量誤差，要求交變的電位準訊號中兩個脈衝的上升邊緣（或下降邊緣）觸發時間一致，和計數和計時器起始和關閉同步。當電機的轉速V較低時，交變的電位準訊號中兩個脈衝產生的間隔寬度Tx較大，較容易控制交變的電位準訊號中兩個脈衝的上升邊緣（或下降邊緣）觸發時間一致，和較容易控制計數和計時器起始和關閉同步，測量精度較高。也即是說，該週期測量法的測量準確度隨著轉速的增大而降低，適合低速測量。而本發明電機是以低速恆速運行，所以誤差較小，測量的電機的轉速V較為準確。It can be understood that due to the measurement error, there are two main errors. One is that the rising edge triggering time of the two pulses in the alternating potential signal may be inconsistent; the second is that the counting and timer start and stop may not be synchronized. Therefore, in order to improve the measurement accuracy and reduce the measurement error, it is required that the rising edge (or falling edge) of the two pulses in the alternating potential signal is triggered at the same time, and the counting and the timer start and stop are synchronized. When the rotational speed V of the motor is low, the interval width Tx generated by the two pulses in the alternating potential signal is large, and it is easier to control the rising edge (or falling edge) triggering time of the two pulses in the alternating potential signal. Consistent, and easier to control the counting and synchronization of the timer start and stop, the measurement accuracy is higher. That is to say, the measurement accuracy of the periodic measurement method decreases as the rotation speed increases, which is suitable for low speed measurement. The motor of the invention runs at a low speed and a constant speed, so the error is small, and the measured motor speed V is relatively accurate.

其中，矽控模組10用於驅動食物料理機中的電機50。零交叉檢測模組20用於檢測輸入至電機50的交流電的零交叉訊號。轉速檢測模組30包括設置在電機轉子上的磁環和與磁環對應設置的霍爾感測器，轉速檢測模組30用於通過霍爾感測器檢測磁環提供的磁場變換訊號以輸出交變的電位準訊號。控制模組40分別與矽控模組10、零交叉檢測模組20和轉速檢測模組30相連，控制模組40用於根據零交叉訊號獲取交流電AC的零交叉點，並在零交叉點延遲第一預設時間T1後輸出開啟脈衝訊號至矽控模組10、且每隔第二預設時間T2輸出一開啟脈衝訊號至矽控模組10，以在食物料理機進行烹飪食物時通過矽控模組10驅動電機50運行，以及根據交變的電位準訊號採用週期測速法獲取電機的轉速V，並根據電機的轉速V第一預設時間T1進行調節電機50低速恆速運行，在食物料理機的烹飪過程中驅動攪拌件60對所烹飪食物進行攪拌，其中，第二預設時間T2為交流電AC的半個週期。The control module 10 is used to drive the motor 50 in the food processor. The zero-cross detection module 20 is for detecting a zero-crossing signal of the alternating current input to the motor 50. The rotation speed detecting module 30 includes a magnetic ring disposed on the rotor of the motor and a Hall sensor disposed corresponding to the magnetic ring, and the rotation speed detecting module 30 is configured to detect the magnetic field conversion signal provided by the magnetic ring through the Hall sensor to output Alternating potential signal. The control module 40 is respectively connected to the control module 10, the zero-cross detection module 20 and the rotation speed detection module 30. The control module 40 is configured to acquire the zero-crossing point of the AC AC according to the zero-cross signal, and delay at the zero-cross point. After the first preset time T1, the pulse signal is output to the control module 10, and an open pulse signal is output to the control module 10 every second preset time T2 to pass through the food cooking machine. The control module 10 drives the motor 50 to operate, and obtains the motor speed V according to the alternating potential signal, and adjusts the motor 50 at a low speed and constant speed according to the motor speed V for the first preset time T1. During the cooking process of the cooking machine, the stirring member 60 is driven to stir the cooked food, wherein the second preset time T2 is a half cycle of the alternating current AC.

在本發明的實施例中，如第2圖所示，磁環302設置在電機本體與電機風葉501之間的轉子轉軸502上，或者設置在電機風葉501下方的轉子轉軸502上，或者設置在電機軸連接器503與電機本體之間的轉子轉軸502上。In the embodiment of the present invention, as shown in FIG. 2, the magnetic ring 302 is disposed on the rotor shaft 502 between the motor body and the motor blades 501, or on the rotor shaft 502 below the motor blades 501, or The rotor shaft 502 is coupled between the motor shaft connector 503 and the motor body.

具體地，如第3圖所示，交流電AC可以為出0～200V的電壓，零交叉檢測單元20可以包括第一電晶體Q1，控制模組40包括兩個檢測埠SENSOR和INT和一控制埠PWM，控制模組40通過埠INT檢測零交叉訊號，通過埠SENSOR檢測交變的電位準訊號，通過埠PWM控制矽控模組10的導通/關斷。進一步地，如第3圖所示，該恆速控制裝置還可以包括開關電源模組70、穩壓模組80、濾波模組90、第二電晶體Q2、供電電源VCC、第一至第五電阻R1至R5和二極體D1等，具體連接方式如第3圖所示此處不再贅述。電機50上電後，INT檢測埠會產生電位準變化，交流電AC經過Q1會產生50Hz/60Hz左右的方波訊號即零交叉訊號。控制模組40根據零交叉訊號獲取交流電AC的零交叉點。控制模組40採用PWM控制，在零交叉點延遲第一預設時間T1後，通過第二電晶體Q2輸出開啟脈衝訊號至矽控模組10，矽控模組10在接收到開啟脈衝訊號後導通，從而使電機50工作，並且，控制模組40每隔T2時間輸出開啟脈衝訊號至矽控模組10，其中，第二預設時間T2等於交流電AC週期的1/2。由於T2是定值，所以控制模組40通過改變第一預設時間T1的大小，即可改變矽控模組10的導通時間，從而改變電機的轉速V。Specifically, as shown in FIG. 3, the alternating current AC may be a voltage of 0 to 200 V, the zero crossing detecting unit 20 may include a first transistor Q1, and the control module 40 includes two detecting ports SENSOR and INT and a control unit.

After the motor 50 is powered on, the INT detection will produce a potential change. The AC AC will generate a square wave signal of 50 Hz/60 Hz or zero cross signal after passing through Q1. The control module 40 acquires the zero crossing point of the alternating current AC according to the zero cross signal. The control module 40 adopts PWM control, and after the first preset time T1 is delayed at the zero crossing point, the opening pulse signal is output to the monitoring module 10 through the second transistor Q2, and the monitoring module 10 receives the opening pulse signal. Turning on, the motor 50 is operated, and the control module 40 outputs an open pulse signal to the control module 10 every T2 time, wherein the second preset time T2 is equal to 1/2 of the AC power cycle. Since T2 is a fixed value, the control module 40 can change the on-time of the control module 10 by changing the size of the first preset time T1, thereby changing the rotational speed V of the motor.

如第2圖所示，磁環302固定在轉子轉軸502上，霍爾感測器301可以固定在電機50的外殼上，電機50通電時，其線圈會產生交變磁場，電機轉子因交變的磁場的動力牽引進行旋轉。磁環302由有磁性和無磁性的塊狀組成，當有磁性的一面靠近霍爾感測器301時，可以改變霍爾感測器301的電位準訊號，當無磁性的一面靠近霍爾感測器301時，霍爾感測器301恢復初始的電位準訊號。因此，如第3圖所示，當磁環302轉動時，會引起靠近它的霍爾感測器301產生交變的電位準訊號，即埠SENSOR會產生交變的電位準訊號因此。控制模組40根據交變的電位準訊號採用週期測速法可以計算出電機的轉速V。最後，控制模組40根據計算出的電機的轉速V，通過改變第一預設時間T1的大小控制電機50低速恆速運行，以在食物料理機的烹飪過程中驅動攪拌件60對所烹飪食物進行攪拌。由此，該裝置通過改變電機矽控模組的導通時間使電機低速恆速運行，從而可以在烹飪過程中對食物進行攪拌，防止食物料理機出現糊底現象。As shown in FIG. 2, the magnetic ring 302 is fixed on the rotor shaft 502, and the Hall sensor 301 can be fixed on the outer casing of the motor 50. When the motor 50 is energized, the coil generates an alternating magnetic field, and the motor rotor is alternating. The magnetic traction of the magnetic field is rotated. The magnetic ring 302 is composed of a magnetic and non-magnetic block. When the magnetic side is close to the Hall sensor 301, the potential signal of the Hall sensor 301 can be changed, and when the non-magnetic side is close to the Hall sense At the time of the detector 301, the Hall sensor 301 restores the initial potential signal. Therefore, as shown in Fig. 3, when the magnetic ring 302 rotates, it causes the Hall sensor 301 near it to generate an alternating potential signal, that is, the 埠SENSOR generates an alternating potential signal. The control module 40 can calculate the rotational speed V of the motor by using the periodic velocity measurement method according to the alternating potential signal. Finally, the control module 40 controls the motor 50 to operate at a low speed and a constant speed according to the calculated rotation speed V of the motor by changing the magnitude of the first preset time T1 to drive the stirring member 60 to the cooked food during the cooking process of the food processor. Stir. Therefore, the device can make the motor run at a low speed and a constant speed by changing the conduction time of the motor control module, so that the food can be stirred during the cooking process to prevent the bottom of the food cooking machine.

進一步地，在本發明的實施例中，控制模組40在零交叉點訊號的上升邊緣到來時延遲第一預設時間T1後輸出開啟脈衝訊號至矽控模組10。Further, in the embodiment of the present invention, the control module 40 outputs a turn-on pulse signal to the control module 10 after the first predetermined time T1 is delayed when the rising edge of the zero-crossing signal arrives.

可以理解的是，如第3圖所示，因為第一電晶體Q1具有導通電壓VT，當A點的電壓大於等於導通電壓VT時，Q1導通，當A點的電壓小於導通電壓VT時，Q1截止。所以，零交叉訊號的電壓零交叉點不是交流電AC真正的零交叉點，存在Δt1時間的延遲。因此，如第4圖所示，在零交叉點訊號的上升邊緣到來時延遲第一預設時間T1後，控制模組40採用PWM技術，輸出開啟脈衝訊號至矽控模組10，矽控模組10在接收到開啟脈衝訊號後導通，從而使電機50工作，並且每隔T2時間輸出開啟脈衝訊號至矽控模組10，其中，第二預設時間T2等於交流電AC週期的1/2。It can be understood that, as shown in FIG. 3, since the first transistor Q1 has the turn-on voltage VT, when the voltage at the point A is greater than or equal to the turn-on voltage VT, Q1 is turned on, and when the voltage at the point A is less than the turn-on voltage VT, Q1 cutoff. Therefore, the zero-crossing point of the zero-crossing signal is not the true zero-crossing point of the AC AC, and there is a delay of Δt1 time. Therefore, as shown in FIG. 4, after the first preset time T1 is delayed when the rising edge of the zero-crossing signal arrives, the control module 40 uses the PWM technology to output the pulse signal to the control module 10, and the control module 10 The group 10 is turned on after receiving the turn-on pulse signal, so that the motor 50 is operated, and the turn-on pulse signal is output to the control module 10 every T2 time, wherein the second preset time T2 is equal to 1/2 of the AC power cycle.

在本發明的實施例中，食物料理機烹飪的食物可以為粥，電機的運行轉速V可以為200轉/分至500轉/分。In the embodiment of the present invention, the food cooked by the food processor may be porridge, and the running speed V of the motor may be 200 rpm to 500 rpm.

在本發明的實施例中，磁環302的級數為偶數且大於等於12級。In the embodiment of the present invention, the number of stages of the magnetic ring 302 is even and greater than or equal to 12.

根據本發明的一實施例，控制模組40根據電機的轉速V對第一預設時間T1進行調節以控制電機50低速恆速運行時，還用於判斷電機的轉速V是否大於目標轉速Vset ，其中，如果電機的轉速V大於目標轉速Vset ，控制模組40則增大第一預設時間T1，通過降低矽控模組10的導通時間以降低電機50的轉速V，直至電機的轉速V等於目標轉速Vset ；如果電機的轉速V小於目標轉速Vset ，控制模組40則減小第一預設時間T1，通過增大矽控模組10的導通時間以提高電機的轉速V，直至電機的轉速V等於目標轉速Vset 。According to an embodiment of the invention, the control module 40 adjusts the first preset time T1 according to the rotational speed V of the motor to control the low speed and constant speed operation of the motor 50, and is also used to determine whether the rotational speed V of the motor is greater than the target rotational speed Vset. If the rotational speed V of the motor is greater than the target rotational speed Vset , the control module 40 increases the first preset time T1, and reduces the rotational speed V of the motor 50 by reducing the conduction time of the control module 10 until the rotational speed of the motor V is equal to the target speed Vset ; if the motor speed V is less than the target speed Vset , the control module 40 is decreased by the first preset time T1, and the turn-on time of the control module 10 is increased to increase the motor speed V. Until the motor speed V is equal to the target speed Vset .

具體地，控制模組40在週期測速法計算出電機的轉速V後，判斷V是否大於Vset ，如果V＞Vset ，說明此時電機的轉速V較高，控制模組40可以通過逐漸增大第一預設時間T1，降低矽控模組10的導通時間，從而降低電機的轉速V，直至V=Vset 。如果V＜Vset ，說明此時電機的轉速V較低，控制模組40可以通過逐漸降低第一預設時間T1，增大矽控模組10的導通時間，從而增大電機的轉速V，直至V=Vset 。而如果V=Vset ，控制模組40控制第一預設時間T1保持在當前大小不變。其中，Vset 一般設置為低速，例如可以為200轉/分至500轉/分，以使電機50帶動攪拌件60進行低速攪拌。Specifically, after the cycle speed measurement method calculates the rotation speed V of the motor, the control module 40 determines whether V is greater than V set . If V>V set , it indicates that the rotation speed V of the motor is high, and the control module 40 can gradually increase. The first first preset time T1 reduces the conduction time of the control module 10, thereby reducing the rotational speed V of the motor until V= Vset . If V<V set , it indicates that the rotational speed V of the motor is low at this time, and the control module 40 can increase the conduction time of the control module 10 by gradually decreasing the first preset time T1, thereby increasing the rotational speed V of the motor. Until V=V set . And if V=V set , the control module 40 controls the first preset time T1 to remain unchanged at the current size. Wherein, V set is generally set to a low speed, for example, 200 rpm to 500 rpm, so that the motor 50 drives the stirring member 60 to perform low speed stirring.

在本發明的實施例中，控制模組40採用週期測速法獲取電機的轉速V時，通過計時器對交變的電位準訊號中兩個脈衝產生的間隔寬度Tx進行測量，並根據兩個脈衝產生的間隔寬度Tx以及磁環轉動一周霍爾感測器301輸出的交變的電位準訊號所對應的脈衝個數N計算電機的轉速V。In the embodiment of the present invention, when the control module 40 obtains the rotational speed V of the motor by using the periodic velocity measurement method, the interval width Tx generated by the two pulses in the alternating potential signal is measured by the timer, and according to the two pulses. The generated interval width Tx and the number N of pulses corresponding to the alternating potential signal output from the Hall sensor 301 at the time of the rotation of the magnetic ring calculate the rotational speed V of the motor.

具體而言，如第6圖所示，電機的轉速V=60/PTx，其中，Tx為交變的電位準訊號中兩個脈衝產生的間隔寬度，P為電機的極對數，由於P為已知量，所示通過檢測出Tx即可計算出電機的轉速V。Tx可以通過計時器和計數器測得，控制模組40根據交變的電位準訊號啟動計時器，同時控制脈衝發生器在Tx內產生基準時鐘脈衝S，計數器對Tx內產生的基準時鐘脈衝S的個數N進行計數，其中，基準時鐘脈衝S的頻率為fc，根據N和fc即可計算出Tx，Tx=N/fc。因此，控制模組40根據以下公式（1）即可計算出電機的轉速V。Specifically, as shown in Fig. 6, the rotational speed of the motor is V=60/PTx, where Tx is the interval width of the two pulses in the alternating potential signal, and P is the pole number of the motor, since P is already Knowing the quantity, the motor speed V can be calculated by detecting Tx. The Tx can be measured by a timer and a counter, and the control module 40 starts the timer according to the alternating potential signal, while the control pulse generator generates the reference clock S in the Tx, and the counter generates the reference clock S generated in the Tx. The number N is counted, wherein the frequency of the reference clock pulse S is fc, and Tx, Tx=N/fc can be calculated from N and fc. Therefore, the control module 40 can calculate the rotational speed V of the motor according to the following formula (1).

V=60fc/PN， （1）V=60fc/PN, (1)

其中，V為電機的轉速，P為電機的極對數，fc為基準時鐘脈衝S的頻率，N為Tx內產生的基準時鐘脈衝S的個數。Where V is the rotational speed of the motor, P is the number of pole pairs of the motor, fc is the frequency of the reference clock pulse S, and N is the number of reference clock pulses S generated in Tx.

可以理解的是，由於存在測量誤差，誤差主要有兩方面，一是交變的電位準訊號中兩個脈衝的上升邊緣觸發時間可能不一致；二是計數和計時器起始和關閉可能不同步。因此，為提高測量精度，減少測量誤差，要求交變的電位準訊號中兩個脈衝的上升邊緣（或下降邊緣）觸發時間一致，和計數和計時器起始和關閉同步。當電機的轉速V較低時，交變的電位準訊號中兩個脈衝產生的間隔寬度Tx較大，較容易控制交變的電位準訊號中兩個脈衝的上升邊緣（或下降邊緣）觸發時間一致，和較容易控制計數和計時器起始和關閉同步，測量精度較高。也即是說，該週期測量法的測量準確度隨著轉速的增大而降低，適合低速測量。而本發明電機50是以低速恆速運行，所以誤差較小，測量的電機的轉速V較為準確。It can be understood that due to the measurement error, there are two main errors. One is that the rising edge triggering time of the two pulses in the alternating potential signal may be inconsistent; the second is that the counting and timer start and stop may not be synchronized. Therefore, in order to improve the measurement accuracy and reduce the measurement error, it is required that the rising edge (or falling edge) of the two pulses in the alternating potential signal is triggered at the same time, and the counting and the timer start and stop are synchronized. When the rotational speed V of the motor is low, the interval width Tx generated by the two pulses in the alternating potential signal is large, and it is easier to control the rising edge (or falling edge) triggering time of the two pulses in the alternating potential signal. Consistent, and easier to control the counting and synchronization of the timer start and stop, the measurement accuracy is higher. That is to say, the measurement accuracy of the periodic measurement method decreases as the rotation speed increases, which is suitable for low speed measurement. The motor 50 of the present invention operates at a low speed and a constant speed, so the error is small, and the measured motor speed V is relatively accurate.

綜上所述，根據本發明實施例的食物料理機的烹飪控制裝置，通過矽控模組驅動食物料理機中的電機，零交叉檢測模組檢測輸入至電機的交流電的零交叉訊號，轉速檢測模組通過霍爾感測器檢測磁環提供的磁場變換訊號以輸出交變的電位準訊號，控制模組根據零交叉訊號獲取交流電的零交叉點，並在零交叉點延遲第一預設時間後輸出開啟脈衝訊號至矽控模組、且每隔第二預設時間輸出一開啟脈衝訊號至矽控模組，以通過矽控模組驅動電機運行，以及根據交變的電位準訊號採用週期測速法獲取電機的轉速，並根據電機的轉速對第一預設時間進行調節以控制電機低速恆速運行，以在食物料理機的烹飪過程中驅動攪拌件對所烹飪食物進行攪拌，防止食物料理機出現糊底現象。In summary, according to the cooking control device of the food processor of the embodiment of the present invention, the motor in the food processor is driven by the control module, and the zero-cross detection module detects the zero-cross signal of the alternating current input to the motor, and the rotation speed is detected. The module detects the magnetic field conversion signal provided by the magnetic ring through the Hall sensor to output the alternating potential signal, and the control module acquires the zero crossing point of the alternating current according to the zero cross signal, and delays the first preset time at the zero crossing point. After the output, the pulse signal is turned on to the control module, and an open pulse signal is output to the control module every second preset time to drive the motor through the control module, and the cycle is based on the alternating potential signal. The speed measurement method obtains the rotation speed of the motor, and adjusts the first preset time according to the rotation speed of the motor to control the low speed and constant speed operation of the motor, so as to drive the stirring member to stir the food cooked during the cooking process of the food cooking machine to prevent food cooking.
