隨著科技的發展，現代人料理食物時經常借助馬達來完成某些費力的工作；舉例來說，各式各樣的攪拌機在諸如煮熱湯或打果汁等不同應用需求中，皆有其適例。然而，倘若攪拌機內所承裝的是高溫的流質物體，當使用者不慎突然加大攪拌機的工作轉速時，極可能造成高溫的流質物體四散噴濺，進而產生危險。 With the development of technology, modern people often use the motor to do some laborious work when cooking food; for example, a variety of mixers have their own applications in different applications such as hot soup or juice. . However, if the mixer is filled with a high-temperature liquid object, when the user accidentally increases the working speed of the mixer, it is highly likely that the high-temperature liquid objects will splatter and cause danger.
且現有的控制模組(圖未示)用於驅動馬達的驅動電壓是以固定變動量調整，具有以下缺點： Moreover, the driving voltage of the existing control module (not shown) for driving the motor is adjusted by a fixed variation, and has the following disadvantages:
1.反應較慢，當負載增加時，無法立即反應。 1. The reaction is slow, and when the load increases, it cannot be reacted immediately.
2.當馬達操作於低速時，若由空載狀態轉變成負載狀態，馬達轉速變動不穩定且不平滑，甚至若負載過大，比如加入一些較難攪動的食物，可能會導致馬達停止轉動。 2. When the motor is operated at low speed, if the load is changed from the no-load state to the load state, the motor speed change is unstable and not smooth. Even if the load is too large, such as adding some foods that are difficult to stir, the motor may stop rotating.

如圖1所示，本發明食物料理機安全裝置100之第一較佳實施例，適用於電連接於一交流電源，該交流電源用以產生一呈弦波且交流的輸入電力，且該食物料理機安全裝 置100包含：一攪拌器150、一馬達170，及一控制模組130。 As shown in FIG. 1 , a first preferred embodiment of the food processor security device 100 of the present invention is adapted to be electrically connected to an AC power source for generating a sine wave and alternating input power, and the food Food safety equipment The device 100 includes an agitator 150, a motor 170, and a control module 130.
該攪拌器150用以攪拌食物。 The agitator 150 is used to stir the food.
該馬達170接收一驅動電壓以轉動該攪拌器150。 The motor 170 receives a drive voltage to rotate the agitator 150.
該控制模組130包括：一驅動器3及一相位控制器4。 The control module 130 includes a driver 3 and a phase controller 4.
驅動器3接收該輸入電壓及一觸發信號，且根據該觸發信號與該輸入電力產生一驅動電壓，該驅動電壓根據該觸發信號於一弦波週期分為非導通區與導通區兩部分，且非導通區對應的驅動電壓幅值為0，而導通區對應的驅動電壓追隨該輸入電壓。 The driver 3 receives the input voltage and a trigger signal, and generates a driving voltage according to the trigger signal and the input power, and the driving voltage is divided into two parts, a non-conducting area and a conducting area, according to the trigger signal in a sine wave period, and The driving voltage corresponding to the conduction region has a magnitude of 0, and the driving voltage corresponding to the conduction region follows the input voltage.
該相位控制器4具有：一偵測單元41、一減法單元42，及一比例積分單元PI。 The phase controller 4 has a detecting unit 41, a subtracting unit 42, and a proportional integrating unit PI.
該偵測單元41偵測該馬達170的轉速以得到一實際轉速。 The detecting unit 41 detects the rotation speed of the motor 170 to obtain an actual rotation speed.
減法單元42電連接於該偵測單元41以接收該實際轉速，且接收一目標轉速，並根據該目標轉速與該實際轉速進行減法運算以得到一轉速差。 The subtraction unit 42 is electrically connected to the detecting unit 41 to receive the actual rotational speed, and receives a target rotational speed, and performs subtraction from the actual rotational speed according to the target rotational speed to obtain a rotational speed difference.
比例積分單元PI電連接於該減法單元42以接收該轉速差，並將該轉速差進行比例積分運算以得到一呈非線性改變的相位變動量，且根據該相位變動量產生該觸發信號。 The proportional integration unit PI is electrically connected to the subtraction unit 42 to receive the rotation speed difference, and performs a proportional integral operation on the rotation speed difference to obtain a phase variation amount that changes nonlinearly, and generates the trigger signal according to the phase fluctuation amount.
在此進一步說明得到該相位變動量的詳細作法：該比例積分單元PI將該轉速差進行正規化以得到一正規值，如式(1)所示：正規值=轉速差/正規預設值………式(1) The detailed method of obtaining the phase fluctuation amount is further described herein: the proportional integration unit PI normalizes the rotation speed difference to obtain a normal value, as shown in the formula (1): a normal value=a rotation speed difference/a regular preset value... ……Formula 1)
該比例積分單元PI儲存一第一對應表(如下所示，但不限於以下數字表示)，並根據該正規值從該第一對應表進行查表以得到一查表值，該第一對應表記錄多個不同的正規值各自對應的一查表值，且該等查表值遞增幅度大於正規值遞增幅度，進一步來說，該查表值的遞增曲線是呈非線性且斜率為正。 The proportional integration unit PI stores a first correspondence table (as shown below, but is not limited to the following numbers), and performs a table lookup from the first correspondence table according to the normal value to obtain a lookup table value, the first correspondence table A look-up table value corresponding to each of the plurality of different normal values is recorded, and the increment of the look-up table values is greater than the increment value of the normal value. Further, the increasing curve of the look-up table value is nonlinear and the slope is positive.

As shown in FIG. 3, the weighting values corresponding to the first, second, and third intervals are 1, 2, and 3, respectively.
該比例積分單元PI根據該查表值與該加權值進行乘法運算以得到一相位變動量，如式(2)所示：相位變動量=查表值×加權值………式(2) The proportional integration unit PI multiplies the weighted value according to the look-up table value to obtain a phase variation amount, as shown in the formula (2): phase fluctuation amount=table value×weight value...(2)
該比例積分單元PI根據該相位變動量來調整該相位指標至一新相位值，並根據該新相位值來產生該觸發信號。 The proportional integration unit PI adjusts the phase index to a new phase value according to the phase fluctuation amount, and generates the trigger signal according to the new phase value.
該比例積分單元PI更接收一空載相位值，且比較該新相位值是否大於該空載相位值，若是，則以該新相位值作為產生該觸發信號的相位角，反之，則以該空載相位值作為產生該觸發信號的相位角以箝制該馬達的轉速。 The proportional integration unit PI further receives a no-load phase value, and compares whether the new phase value is greater than the no-load phase value. If yes, the new phase value is used as a phase angle for generating the trigger signal, and vice versa. The phase value is used as the phase angle at which the trigger signal is generated to clamp the rotational speed of the motor.
如圖4所示，本發明食物料理機安全裝置100之第二較佳實施例100包括一轉速偵測單元110、一溫度偵測單元120，以及一控制模組130。為方便解釋，圖中更繪示食物料理機安全裝置100所施予作用之工作件(Workpiece)，亦即容器201與攪拌器202；換句話說，食物料理機安全裝置100在定義上可以僅包含轉速偵測單元110、溫度偵測單元120與控制模組130，三者只要其相互間作動關係如下列實施方式所述，即不脫本發明之教示範圍。此外，該攪拌器202可為一刀具。 As shown in FIG. 4, the second preferred embodiment 100 of the food processor safety device 100 of the present invention includes a rotation speed detecting unit 110, a temperature detecting unit 120, and a control module 130. For convenience of explanation, the figure further shows the work piece to which the food processor safety device 100 is applied, that is, the container 201 and the agitator 202; in other words, the food processor safety device 100 can be defined only by The rotation detecting unit 110, the temperature detecting unit 120 and the control module 130 are included, and the three are as described in the following embodiments as long as they do not deviate from the teaching scope of the present invention. Additionally, the agitator 202 can be a tool.
承前所述，轉速偵測單元110係用以偵測容器201中之攪拌器202的轉速；溫度偵測單元120則係用以偵測容器201的溫度。控制模組130於攪拌器202的轉速111低於一安全轉速預設值，且容器201的溫度121高於一安全溫度預設值時，控制攪拌器202的轉速，使其不超過一噴濺轉速臨界值。 As described above, the rotation speed detecting unit 110 is configured to detect the rotation speed of the agitator 202 in the container 201; the temperature detecting unit 120 is configured to detect the temperature of the container 201. The control module 130 controls the rotation speed of the agitator 202 to be no more than a splash when the rotational speed 111 of the agitator 202 is lower than a preset value of the safe rotational speed and the temperature 121 of the container 201 is higher than a preset value of the safe temperature. Speed threshold.
舉例來說，假設容器201的溫度121是安全溫度預設值(例如攝氏60度)以下，則縱令攪拌器202的轉速111在時間軸上劇增，產生噴濺，亦不至於造成燒燙傷；故而控制模組130不需要限制攪拌器202的轉速111，使其低於 噴濺轉速臨界值(例如每分鐘1000轉)。另一方面，假設容器201的溫度121高於安全溫度預設值(例如攝氏80度)，此時若攪拌器202的轉速111已高於安全轉速預設值(例如每分鐘50轉)，縱令將攪拌器202的轉速111拉升至超過噴濺轉速臨界值的高轉速(例如每分鐘2000轉)，實亦不生噴濺，蓋因物質的動摩擦係數恆遠小於靜摩擦係數也。 For example, assuming that the temperature 121 of the container 201 is below a safe temperature preset value (for example, 60 degrees Celsius), the rotational speed 111 of the agitator 202 is increased sharply on the time axis, causing splashing, and does not cause burns; Therefore, the control module 130 does not need to limit the rotational speed 111 of the agitator 202 to be lower than Splash speed threshold (eg 1000 rpm). On the other hand, it is assumed that the temperature 121 of the container 201 is higher than the preset value of the safe temperature (for example, 80 degrees Celsius), and if the rotational speed 111 of the agitator 202 is higher than the preset value of the safe speed (for example, 50 revolutions per minute), The rotation speed 111 of the agitator 202 is pulled up to a high rotation speed exceeding the critical value of the spray rotation speed (for example, 2000 revolutions per minute), and no splash is actually generated, and the dynamic friction coefficient of the cover due to the material is far less than the static friction coefficient.
因此，本實施方式之食物料理機安全裝置100的致動時機為當容器201的溫度121高於安全溫度預設值(例如攝氏80度)，而且攪拌器202的轉速111低於安全轉速預設值(例如每分鐘50轉)，此時若使用者下達指令要將攪拌器202的轉速111提升至超過噴濺轉速臨界值的高轉速(例如每分鐘2000轉)，本實施方式之食物料理機安全裝置100會因條件滿足而強制將攪拌器202的轉速111控制在噴濺轉速臨界值(例如每分鐘1000轉)之下。 Therefore, the timing of actuation of the food processor safety device 100 of the present embodiment is when the temperature 121 of the container 201 is higher than a preset value of the safety temperature (for example, 80 degrees Celsius), and the rotation speed 111 of the agitator 202 is lower than the safety speed preset. a value (for example, 50 revolutions per minute). At this time, if the user issues an instruction to raise the rotational speed 111 of the agitator 202 to a high rotational speed exceeding a critical value of the spattering rotational speed (for example, 2000 revolutions per minute), the food cooking machine of the present embodiment The safety device 100 will force the rotational speed 111 of the agitator 202 to be below the splash rotational speed threshold (e.g., 1000 revolutions per minute) due to conditions being met.
藉此，即可避免容器201內高溫的物質，因突然受力攪拌而噴濺。具體而言，上述諸參數的設計考量如下：安全轉速預設值與噴濺轉速臨界值之間距可設計正比於攪拌器之阻尼係數；易言之，攪拌器202的阻尼係數越小，暫態響應時間越短，從低轉速拉升到高轉速的時間越快，容器201內流體物質單位時間內受力越大，越容易造成噴濺；因此，安全轉速預設值與噴濺轉速臨界值之間的轉速差值必須相應縮短，例如安全轉速預設值仍為每分鐘50轉，但噴濺轉速臨界值從原設定每分鐘1000轉降至每分鐘500轉。 Thereby, the high temperature substance in the container 201 can be avoided, and the splash is caused by sudden force stirring. Specifically, the design considerations of the above parameters are as follows: the distance between the preset value of the safe speed and the critical value of the splash speed can be designed to be proportional to the damping coefficient of the agitator; in other words, the smaller the damping coefficient of the agitator 202, the transient state The shorter the response time, the faster the time from the low speed to the high speed. The greater the force of the fluid material in the container 201 per unit time, the more likely it is to cause splashing; therefore, the safe speed preset value and the splash speed threshold The difference between the speeds must be shortened accordingly. For example, the safe speed preset value is still 50 rpm, but the splash speed threshold is reduced from 1000 rpm to 500 rpm.
同理，安全溫度預設值亦可設計正比於攪拌器202之阻尼係數；承上所述，攪拌器202的阻尼係數越大，越不易造成噴濺，故而可以匹配較大的安全溫度預設值。舉例來說，設若有兩架攪拌機皆配以本實施方式之食物料理機安全裝置100；第一台攪拌機的攪拌器202之阻尼係數較大，則攪拌器202的轉速拉升時間較長，流體物質單位時間內受力較小，所以不易噴濺，可以設定較高的安全溫度預設值(例如攝氏85度)。反之，第二台攪拌機的攪拌器202之阻尼係數較小，則攪拌器202的轉速拉升時間較短，流體物質單位時間內受力較大，所以較易噴濺，因而應設定較低的安全溫度預設值(例如攝氏75度)。整體而言，此舉在於提供攪拌機製造者設計上的自由度。 Similarly, the preset value of the safety temperature can also be designed proportional to the damping coefficient of the agitator 202; as described above, the larger the damping coefficient of the agitator 202, the less likely it is to cause splashing, so that it can match a larger safe temperature preset. value. For example, if there are two mixers equipped with the food processor safety device 100 of the present embodiment; the agitator of the first mixer has a larger damping coefficient, and the agitator 202 has a longer rotation speed, the fluid The material is less stressed during the unit time, so it is not easy to splash. You can set a higher safe temperature preset (for example, 85 degrees Celsius). On the contrary, if the damping coefficient of the agitator 202 of the second mixer is small, the rotation speed of the agitator 202 is short, and the fluid material is subjected to a large force per unit time, so it is easy to be sprayed, so the setting should be lower. Safe temperature preset (eg 75 degrees Celsius). Overall, this is to provide the degree of freedom in the design of the mixer manufacturer.
另一方面，安全溫度預設值也可以設計成反比於容器201所承裝之內容物的黏滯度；亦即當受攪拌的流質物體較黏稠時，其噴濺時產生的燒燙傷亦較嚴重，故而應匹配較小的安全溫度預設值。舉例來說，熱茶攪拌器與濃湯攪拌器在設計上，因為濃湯的黏滯度較大，噴濺時產生的燒燙傷較嚴重，故而應佐以相對較低的安全溫度預設值。 On the other hand, the preset value of the safe temperature can also be designed to be inversely proportional to the viscosity of the contents of the container 201; that is, when the agitated liquid object is thicker, the burnt burn caused by the splash is also higher. Severe, it should match a smaller safe temperature preset. For example, hot tea blenders and soup blenders are designed because the viscosity of the soup is large, and the burns caused by splashing are more serious, so it should be accompanied by a relatively low safety temperature preset. .
如5圖所示，為本發明食物料理機安全裝置之第三較佳實施例的功能方塊圖。圖5中，食物料理機安全裝置100在定義上也可以包含轉速偵測單元110、溫度偵測單元120、控制模組130、容器140、攪拌器150、轉速設定介面160與馬達170。易言之，容器140、攪拌器150、轉速設定介面160與馬達170可為本實施方式之食物料理機安全 裝置100的環境元件(Envi ronment element)。更進一步的說明如下：轉速偵測單元110可以是光遮斷式感應器，直接偵測攪拌器150的轉速；其亦可為電流大小偵測器，直接偵測馬達170之電流的大小，即可知其轉速。舉例來說，電流大小偵測器可以用直接式或間接式的測量元件來實現，後者例如赫姆霍茲線圈(Helmhol tz coi l)。轉速設定介面160係用以輸入轉速設定值161予控制模組130，控制模組130便可視情況選擇將攪拌器150的轉速推升至轉速設定值161，或如前所述限定於噴濺轉速臨界值內。另一方面，馬達170可以是諸如步進馬達或線性馬達等電動機。 As shown in Fig. 5, it is a functional block diagram of a third preferred embodiment of the food processor safety device of the present invention. In FIG. 5, the food processor safety device 100 may also include a rotation speed detecting unit 110, a temperature detecting unit 120, a control module 130, a container 140, an agitator 150, a rotational speed setting interface 160, and a motor 170. In other words, the container 140, the agitator 150, the rotational speed setting interface 160 and the motor 170 can be safe for the food processor of the present embodiment. An environmental element of the device 100. The further description is as follows: the rotation speed detecting unit 110 can be a light blocking type sensor, and directly detects the rotation speed of the agitator 150; or it can be a current magnitude detector to directly detect the current of the motor 170, that is, The speed is known. For example, the current magnitude detector can be implemented with direct or indirect measuring elements such as Helmholtz coils (Helmholtz Coil). The speed setting interface 160 is used to input the speed setting value 161 to the control module 130. The control module 130 can optionally push the speed of the agitator 150 to the speed setting value 161, or is limited to the splashing speed as described above. Within the critical value. On the other hand, the motor 170 may be an electric motor such as a stepping motor or a linear motor.
如6圖所示，為本發明第二較佳實施例之控制模組130的邏輯電路圖；為方便解釋，圖中更繪示轉速設定介面160與馬達170。控制模組130的邏輯電路可以用軟體、韌體或硬體的方式來實現；圖3所繪示之控制模組130的邏輯電路圖，僅為一適例，而非為限制者。圖6中，判斷式：安全轉速預設值是否大於攪拌器150目前的轉速，與判斷式：容器140的溫度是否大於安全溫度預設值，兩者經過邏輯及閘運算後，將結果匯入選擇器；若兩個判斷式皆被滿足，邏輯及閘輸出1，使選擇器選用噴濺轉速臨界值來驅動馬達170。反之，若兩判斷式中任一不成立，則邏輯及閘輸出0，使選擇器選用轉速設定介面提供的轉速設定值來驅動馬達170。當然，轉速偵測單元110與溫度偵測單元120會隨設定而週期性運作；故而控制模組130所下達的命令也是隨時視實際狀況之變動而調整。 As shown in FIG. 6 , it is a logic circuit diagram of the control module 130 according to the second preferred embodiment of the present invention; for convenience of explanation, the rotation speed setting interface 160 and the motor 170 are further illustrated. The logic circuit of the control module 130 can be implemented in a software, firmware or hardware manner; the logic circuit diagram of the control module 130 shown in FIG. 3 is only a suitable example, not a limitation. In Fig. 6, the judgment formula: whether the preset value of the safety speed is greater than the current rotation speed of the agitator 150, and the judgment formula: whether the temperature of the container 140 is greater than the preset value of the safety temperature, and after the logic and the gate operation are performed, the result is imported. The selector; if both judgments are satisfied, the logic and gate outputs 1, causing the selector to select the spray speed threshold to drive the motor 170. Conversely, if either of the two judgments does not hold, the logic and gate outputs 0, causing the selector to select the speed setpoint provided by the speed setting interface to drive the motor 170. Of course, the speed detecting unit 110 and the temperature detecting unit 120 periodically operate with the setting; therefore, the commands issued by the control module 130 are also adjusted at any time depending on the actual situation.
綜上所述，上述實施例具有以下優點： In summary, the above embodiment has the following advantages:
1.反應較快，利用查表與加權值來增加轉速的變動量，因此當負載變動時，能立即反應。 1. The reaction is faster, and the metering and weighting values are used to increase the amount of fluctuation of the rotation speed, so that when the load changes, the reaction can be immediately performed.
2.當馬達170操作於低速時，藉由該空載相位值來箝制驅動電壓以維持馬達轉速，若由空載狀態轉變成負載狀態，馬達轉速變動穩定且平滑。 2. When the motor 170 is operated at a low speed, the driving voltage is clamped by the no-load phase value to maintain the motor rotation speed, and if the idle state is changed to the load state, the motor rotation speed fluctuation is stable and smooth.
3.避免高溫的流質物體四散噴濺，解決習知攪拌機所可能造成的危險。 3. Avoid high-temperature liquid objects splashing around, to solve the dangers that may be caused by conventional mixers.
4.提供各種配套設計機制，以適切因應不同需求之各種習知攪拌機的安全設定方式。 4. Provide a variety of matching design mechanisms to suit the safety settings of various conventional mixers for different needs.
惟以上所述者，僅為本發明之較佳實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
