Description

鍋具的加熱方法 Pot heating method

本發明係與瓦斯器具控制有關;特別是指一種鍋具的加熱方法。 The invention relates to the control of gas appliances; in particular to a heating method of a pan.

按,目前用於烹煮大量食材的器具通常是以瓦斯鍋為主,以瓦斯飯鍋為例,瓦斯飯鍋相較於電子飯鍋的優點在於瓦斯費較電費便宜,而且燃燒瓦斯所產生的熱能大於使用電力產生的熱能,使得鍋具內的米和水可充分混合,煮好的飯口感較佳,且烹煮的時間短。 According to the current cooking utensils, the cooking utensils are mainly based on gas pots. For example, the gas rice cooker has the advantage over the electronic rice cooker that the gas cost is cheaper than the electricity cost, and the gas is produced by burning the gas. The heat energy is greater than the heat energy generated by the use of electricity, so that the rice and water in the pot can be well mixed, the cooked rice tastes better, and the cooking time is short.

習用的瓦斯鍋之加熱裝置利用一熱膨脹開關感應鍋具的溫度,在該鍋具的溫度上升到預設的溫度(常見為攝氏135度)時,熱膨脹開關作動阻斷瓦斯的供應,而停止加熱。 The conventional gas heater heating device uses a thermal expansion switch to sense the temperature of the pan. When the temperature of the pan rises to a preset temperature (usually 135 degrees Celsius), the thermal expansion switch acts to block the supply of gas and stop heating. .

習用的瓦斯鍋用於煮湯或燉煮食材時,持續的大火加熱只會破壞食材的外觀,無法將食材的精華熬煮到湯裡。此外,鍋內食材的湯汁會一直被煮到收乾,鍋具的溫度才能達到攝氏135度,此際才會停止加熱,因此,用於煮水、煮湯或燉煮食材時仍需人員在一旁看顧,使用上頗有不便。是以,習用的瓦斯鍋之設計仍未臻完善,尚有待改進之處。 When a conventional gas pot is used to cook soup or stew ingredients, continuous heat heating will only destroy the appearance of the ingredients, and the essence of the ingredients cannot be cooked into the soup. In addition, the soup in the pot will be cooked until it is dried, and the temperature of the pot can reach 135 degrees Celsius, so heating will stop. Therefore, it is still needed for boiling water, soup or stewed ingredients. Looking around, it is quite inconvenient to use. Therefore, the design of the conventional gas pot is still not perfect, and there is still room for improvement.

有鑑於此,本發明之目的在於提供一種鍋具的加熱控制方法,可精確地對鍋具進行加熱。 In view of the above, an object of the present invention is to provide a heating control method for a pan, which can accurately heat the pan.

緣以達成上述目的,本發明所提供鍋具的加熱方法,係應用於一加熱裝置,該加熱裝置用以燃燒瓦斯以對該鍋具進行加熱,該鍋具供容裝一被加熱物,該加熱方法包括下列步驟:a、提供具有一第一瓦斯流量的瓦斯至該加熱裝置,以加熱該鍋具;b、監測該鍋具之溫度,並取得該鍋具之溫度由一第一溫度上升至一第二溫度的一加熱時間;c、依據該第一瓦斯流量及該加熱時間判斷該鍋具內該被加熱物的重量;d、在該鍋具的溫度達到一第三溫度時,將依據該被加熱物的重量提供具有一第二瓦斯流量的瓦斯至該加熱裝置,其中,該第二瓦斯流量小於該第一瓦斯流量。 In order to achieve the above object, the heating method of the cookware provided by the present invention is applied to a heating device for burning gas to heat the pan, and the pan is for accommodating a heated object. The heating method comprises the steps of: a, supplying a gas having a first gas flow rate to the heating device to heat the pan; b, monitoring the temperature of the pan, and obtaining the temperature of the pan from a first temperature rise a heating time to a second temperature; c, determining the weight of the object to be heated in the pan according to the first gas flow rate and the heating time; d, when the temperature of the pan reaches a third temperature, Gas having a second gas flow rate is supplied to the heating device according to the weight of the object to be heated, wherein the second gas flow rate is less than the first gas flow rate.

本發明之效果在於藉由計算被加熱物的重量,可推算出第二瓦斯流量,精確的對鍋具加熱,讓烹煮好的食物品質一致,並使瓦斯器具能針對不同的食材、份量及料理模式進行烹煮,以達到多用途的功能。 The effect of the invention is that by calculating the weight of the object to be heated, the second gas flow rate can be calculated, the panware can be accurately heated, the quality of the cooked food can be consistent, and the gas appliance can be used for different ingredients, portions and The cooking mode is cooked to achieve a versatile function.

為能更清楚地說明本發明,茲舉較佳實施例並配合圖示詳細說明如後。 In order that the present invention may be more clearly described, the preferred embodiments are illustrated in the accompanying drawings.

請參閱圖1,為應用本發明第一較佳實施例加熱控制方法之瓦斯器具100,用以加熱一鍋具200,該瓦斯器具100包含有一瓦斯閥10、一加熱裝置20、一溫度感測器30、一控制單元40、一輸入單元50以及一記憶體60。 Referring to FIG. 1 , a gas appliance 100 for applying a heating control method according to a first preferred embodiment of the present invention is used to heat a pot 200. The gas appliance 100 includes a gas valve 10 , a heating device 20 , and a temperature sensing method. The device 30, a control unit 40, an input unit 50 and a memory 60.

該輸入單元50為觸控顯示面板,在加熱該鍋 具200前供使用者進行不同的加熱模式設定,例如,煮開水模式、煮湯模式、煮飯模式或滷食物模式等不同模式,該些加熱模式係儲存於記憶體60內。該控制單元40依據使用者所選擇的加熱模式,並從記憶體60內提取其中一該加熱模式,以控制該瓦斯閥10的動作,每一該加熱模式係對應一個預定時間,預定時間是作為中止供應瓦斯之依據。 The input unit 50 is a touch display panel, and the pot is heated Before the 200, the user can perform different heating mode settings, for example, boil water mode, soup mode, rice cooking mode or halogen food mode, and the heating modes are stored in the memory 60. The control unit 40 extracts one of the heating modes from the memory 60 according to the heating mode selected by the user to control the action of the gas valve 10, and each of the heating modes corresponds to a predetermined time, and the predetermined time is Suspension of the basis for the supply of gas.

該瓦斯閥10設置於連通至該加熱裝置20的一 瓦斯管路12上,該瓦斯閥10係受控制地調節供輸至該加熱裝置20的瓦斯流量。實務上,該瓦斯閥10可採用瓦斯比例閥、步進閥等受控制訊號驅動而改變通過的瓦斯流量之方式設計。該加熱裝置20接收來自該瓦斯閥10的瓦斯並燃燒,以加熱置於其上方的鍋具200。 The gas valve 10 is disposed in a communication to the heating device 20 On the gas line 12, the gas valve 10 is controlled to regulate the flow of gas to the heating unit 20. In practice, the gas valve 10 can be designed in such a manner that a gas proportional valve, a stepping valve, or the like is driven by a control signal to change the flow rate of the gas passing therethrough. The heating device 20 receives gas from the gas valve 10 and burns to heat the pan 200 placed above it.

該溫度感測器30為一負溫度係數熱敏電阻感 測器(NTC Thermistor),該溫度感測器30接觸該鍋具200的底部,用於監測該鍋具200的溫度,並依據該鍋具200的溫度,輸出一對應之類比的電訊號。 The temperature sensor 30 is a negative temperature coefficient thermistor The temperature sensor 30 contacts the bottom of the pot 200 for monitoring the temperature of the pot 200, and outputs a corresponding analog electric signal according to the temperature of the pot 200.

該控制單元40電性連接該溫度感測器30、該 瓦斯閥10、該記憶體60及該輸入單元50。該控制單元40包含有一類比/數位轉換電路42、一運算電路44、一控制電路46與一計時器48。該類比/數位轉換電路42將該溫度感測器30所輸出的電訊號轉換成數位的電位數值並輸出到該運算電路44,由於該溫度感測器30為負溫度係數,因此,對應其輸出的電訊號的電位數值係隨著溫度上升而下降。該運算電路44以所接收的電位數值為基礎計算該鍋具200受熱時的溫度變化,並依據所計算的溫度變化判斷當前該鍋具200加熱的狀態。此外該運算電路44更透過該控制電路46輸出對應的控制訊號至該瓦斯閥10,以控制瓦斯流量。該計時器48則用於計時該加熱鍋具200所需要的時間。 The control unit 40 is electrically connected to the temperature sensor 30, and the The gas valve 10, the memory 60 and the input unit 50. The control unit 40 includes an analog/digital conversion circuit 42, an arithmetic circuit 44, a control circuit 46, and a timer 48. The analog/digital conversion circuit 42 converts the electrical signal output by the temperature sensor 30 into a potential value of a digital digit and outputs it to the arithmetic circuit 44. Since the temperature sensor 30 has a negative temperature coefficient, it corresponds to its output. The potential value of the electrical signal decreases as the temperature rises. The arithmetic circuit 44 calculates the temperature change of the pan 200 when it is heated based on the received potential value, and determines the current state of heating of the pan 200 according to the calculated temperature change. In addition, the operation circuit 44 further outputs a corresponding control signal to the gas valve 10 through the control circuit 46 to control the gas flow rate. The timer 48 is used to time the heating pot 200.

此外,本發明於進行加熱控制之前,預先於該 記憶體60建立一瓦斯流量對照表,該瓦斯流量對照表包括複數個參考重量以及對應的複數個參考瓦斯流量,其中,該些參考重量是對應鍋具200內不同重量的被加熱物210,參考重量愈重,所對應的參考瓦斯流量愈高,例如,當該被加熱物210的重量為1公斤時,提供第一段的參考瓦斯流量;當該被加熱物210的重量為1.5公斤時,提供第二段的參考瓦斯流量,第二段的參考瓦斯流量大於第一段的參考瓦斯流量。該瓦斯流量對照表係供依據被加熱物的重量調整瓦斯流量,其使用方式容後再述。 In addition, the present invention is prior to the heating control The memory 60 establishes a gas flow comparison table. The gas flow comparison table includes a plurality of reference weights and a corresponding plurality of reference gas flows, wherein the reference weights are corresponding to the weights of the objects 210 in the pan 200, The heavier the weight, the higher the reference gas flow rate, for example, when the weight of the object to be heated 210 is 1 kg, the reference gas flow rate of the first stage is provided; when the weight of the object to be heated 210 is 1.5 kg, The reference gas flow of the second stage is provided, and the reference gas flow of the second stage is greater than the reference gas flow of the first stage. The gas flow comparison table is for adjusting the gas flow rate according to the weight of the object to be heated, and the manner of use thereof will be described later.

藉此,利用上述結構設計,透過圖2所示之加 熱方法,即可對鍋具200內的被加熱物210進行加熱,被加熱物210是指食材、水、調味料或其混合物。本發明的加熱方法包括下列步驟:步驟S110:選擇加熱模式。在本步驟中,使用者先在鍋具200內放置被加熱物210,並藉由該輸入單元50由該些加熱模式中選擇其中一該加熱模式。 Thereby, using the above structural design, through the addition shown in FIG. The heat method 210 can heat the object to be heated 210 in the pan 200, and the object to be heated 210 means food, water, seasoning or a mixture thereof. The heating method of the present invention comprises the following steps: Step S110: Selecting a heating mode. In this step, the user first places the object to be heated 210 in the pan 200, and the heating unit selects one of the heating modes by the input unit 50.

步驟S120:提供具有第一瓦斯流量的瓦斯至加 熱裝置20。在本步驟中,該控制單元40控制該瓦斯閥10的開啟程度,使通過該瓦斯閥10的瓦斯具有第一瓦斯流量,之後該加熱裝置20點燃瓦斯,以對該鍋具200加熱。 Step S120: providing gas to plus gas with first gas flow Thermal device 20. In this step, the control unit 40 controls the degree of opening of the gas valve 10 such that the gas passing through the gas valve 10 has a first gas flow rate, after which the heating device 20 ignites the gas to heat the pan 200.

步驟S130:監測鍋具200之溫度,並取得鍋具 200之溫度由一第一溫度上升至一第二溫度的一加熱時間。在本步驟中,該鍋具200在加熱的同時,該溫度感測器30感測該鍋具200的溫度,而所對應的電位數值隨著該鍋具200的溫度上升而下降,再依據類比/數位轉換電路42及該運算電路44,計算出鍋具200內的實際溫度變化。 Step S130: monitoring the temperature of the pan 200 and obtaining the pan The temperature of 200 is raised from a first temperature to a heating time of a second temperature. In this step, while the pot 200 is being heated, the temperature sensor 30 senses the temperature of the pot 200, and the corresponding potential value decreases as the temperature of the pot 200 rises, and then according to the analogy The /bit conversion circuit 42 and the arithmetic circuit 44 calculate the actual temperature change in the pan 200.

在此同時,該計時器48則計算鍋具200由該 第一溫度上升至該第二溫度所花費的時間,本實施例中,第一溫度是以攝氏50度為例,第二溫度是以攝氏90度為例。 At the same time, the timer 48 calculates the pot 200 from the The time taken for the first temperature to rise to the second temperature. In this embodiment, the first temperature is taken as an example of 50 degrees Celsius, and the second temperature is taken as an example of 90 degrees Celsius.

步驟S140:依據第一瓦斯流量及該加熱時間判 斷鍋具200內該被加熱物210的重量。在本步驟中,先將該第一瓦斯流量與該加熱時間相乘,而得到一瓦斯消耗量。然後,運算電路44藉由計算式m=H/(△T×K)計算而得到該被加熱物210的重量,其中m為該被加熱物210的重量;H為對應該瓦斯消耗量之能量,即為瓦斯消耗量乘以單位瓦斯量的熱值;△T為該第一溫度與該第二溫度之間的溫度差;K為該被加熱物210之比熱,而在進行煮或滷食物的過程中,通常水在被加熱物210中佔有最大比例,因此可設定K為水的比熱。 Step S140: Determine the weight of the object to be heated 210 in the pot 200 according to the first gas flow rate and the heating time. In this step, the first gas flow rate is first multiplied by the heating time to obtain a gas consumption amount. Then, the arithmetic circuit 44 calculates the weight of the object to be heated 210 by calculating the formula m = H / (ΔT × K), where m is the weight of the object to be heated 210; H is the energy corresponding to the gas consumption. That is, the gas consumption is multiplied by the calorific value of the unit gas volume; ΔT is the temperature difference between the first temperature and the second temperature; K is the specific heat of the object to be heated 210, and the boiled or halogenated food is being cooked. In the process, water usually occupies the largest proportion in the object to be heated 210, so K can be set as the specific heat of water.

步驟S150:在該鍋具200的溫度達到一第三溫 度時,將提供至加熱裝置20的瓦斯流量由該第一瓦斯流量改為一第二瓦斯流量,且第二瓦斯流量小於第一瓦斯流量,該第三溫度在本實施例為攝氏100度。在本步驟中,先持續提供具有該第一瓦斯流量的瓦斯至該加熱裝置20,使該鍋具200到達第三溫度後,該控制電路46依據該被加熱物210的重量,輸出對應的控制訊號至該瓦斯閥10,使瓦斯閥10提供具有第二瓦斯流量的瓦斯至該加熱裝置20,使該鍋具200的溫度維持於該第三溫度。 Step S150: The temperature of the pot 200 reaches a third temperature. At the time, the gas flow rate supplied to the heating device 20 is changed from the first gas flow rate to a second gas flow rate, and the second gas flow rate is less than the first gas flow rate, which is 100 degrees Celsius in this embodiment. In this step, the gas having the first gas flow rate is continuously supplied to the heating device 20, and after the pan 200 reaches the third temperature, the control circuit 46 outputs corresponding control according to the weight of the object to be heated 210. Signaling to the gas valve 10 causes the gas valve 10 to provide gas having a second gas flow rate to the heating device 20 to maintain the temperature of the pan 200 at the third temperature.

到達該第三溫度的判斷,是該控制電路46判 斷當該鍋具200之溫度持續一段時間不再變化時(即被加熱物210以達煮沸狀態),則判斷該鍋具200到達該第三溫度。 實務上,亦可是監測該鍋具200受熱時由第一溫度至第二溫度的一升溫斜率,且在該升溫斜率的絕對值小於一預定值時,判斷該鍋具200之溫度到達該第三溫度;或者是由溫度感測器30直接測量而得該鍋具200的溫度達到該第三溫度。 The determination to reach the third temperature is determined by the control circuit 46 When the temperature of the pan 200 does not change for a while (ie, the object 210 is heated to reach the boiling state), it is judged that the pan 200 reaches the third temperature. In practice, it is also possible to monitor a temperature rise slope from the first temperature to the second temperature when the pot 200 is heated, and determine that the temperature of the pot 200 reaches the third when the absolute value of the temperature increase slope is less than a predetermined value. The temperature is either directly measured by the temperature sensor 30 to obtain the temperature of the pan 200 to reach the third temperature.

當鍋具200到達該第三溫度時,通常會是鍋具 200內的被加熱物210以達煮沸狀態,而之後所提供的瓦斯流量只要保持被加熱物210為煮沸狀態即可,因此第二瓦斯流量會小於該第一瓦斯流量,以避免火力太大而導致被加熱物210燒焦,或鍋具200內的水溢出。 When the pot 200 reaches the third temperature, it is usually a pot The object to be heated 210 in 200 is in a boiling state, and then the gas flow rate provided is as long as the object to be heated 210 is boiled, so the second gas flow rate is smaller than the first gas flow rate to avoid too much fire power. The object to be heated 210 is burnt or the water in the pan 200 overflows.

本實施例第二瓦斯流量的大小是由比對該記 憶體60內的該瓦斯流量對照表而取得較佳的瓦斯流量。將步驟140中所計算的被加熱物210的重量與該瓦斯流量對照表的參考重量比對,再將對應的參考瓦斯流量設定為該第二瓦斯流量。這種設計可依據該被加熱物210的重量的多寡,以提供不同的第二瓦斯流量的大小,可避免因溫度太高而導致鍋具200內的食材燒焦,或者溫度太低而導致食材無法煮熟。 The size of the second gas flow in this embodiment is determined by the ratio The gas flow comparison table in the body 60 is used to obtain a better gas flow rate. The weight of the object to be heated 210 calculated in step 140 is compared with the reference weight of the gas flow comparison table, and the corresponding reference gas flow rate is set to the second gas flow rate. This design can be based on the weight of the object to be heated 210 to provide a different second gas flow rate, which can avoid the scorching of the food in the pot 200 due to too high temperature, or the temperature is too low to cause the ingredients. Unable to cook.

步驟S160:依據該加熱模式,使提供至該加熱 裝置20的第二瓦斯流量在持續供輸一預定時間後,中止瓦斯至該加熱裝置20。在本步驟中,該控制單元40依據於步驟S110中所選擇的加熱模式,以持續提供第二瓦斯流量一段時間,例如選擇煮開水模式,則提供第二瓦斯流量的瓦斯持續1分鐘;選擇煮湯模式,則提供第二瓦斯流量的瓦斯持續5分鐘;選擇滷食物模式,則提供第二瓦斯流量的瓦斯持續30分鐘。當過了預定時間後,控制電路46輸出對應的控制訊號至該瓦斯閥10,以關閉瓦斯。本發明藉由不同的加熱方式,可滿足使用者不同的需求,使瓦斯器具100能達到多用途的目的。 Step S160: providing the heating to the heating mode according to the heating mode The second gas flow of the apparatus 20 stops the gas to the heating device 20 after continuing to supply for a predetermined time. In this step, the control unit 40 continues to provide the second gas flow for a period of time according to the heating mode selected in step S110, for example, selecting the boiling water mode, then providing the gas of the second gas flow for 1 minute; selecting to cook In the soup mode, the gas for the second gas flow is continued for 5 minutes; when the halogen food mode is selected, the gas for the second gas flow is provided for 30 minutes. When the predetermined time has elapsed, the control circuit 46 outputs a corresponding control signal to the gas valve 10 to turn off the gas. The invention can meet the different needs of the user by different heating methods, and the gas appliance 100 can achieve the purpose of multi-purpose.

在第二實施例中,亦可將該第二溫度與該第三 溫度同樣設定為攝氏100度,即,該鍋具200在達100度時,並計算完加熱時間後,緊接著計算被加熱物210的重量,而後將供給該加熱裝置20的瓦斯流量改為該第二瓦斯流量。 In the second embodiment, the second temperature and the third may also be The temperature is also set to 100 degrees Celsius, that is, when the pan 200 reaches 100 degrees, and after the heating time is calculated, the weight of the object to be heated 210 is calculated, and then the gas flow rate supplied to the heating device 20 is changed to Second gas flow.

在第三實施例中,於步驟S150到步驟S160之 間,可再加入一判斷步驟,其用以判斷該鍋具200之溫度在提供第二瓦斯流量時,是否大於或小於該第三溫度。當該鍋具200之溫度大於該第三溫度時,表示鍋具200內已無水分,則判斷該鍋具200為空燒狀態,則中止提供瓦斯至該加熱裝置20,以避免鍋具200的損壞或者發生火災。而當該鍋具200之溫度由第三溫度下降至小於該第三溫度的一第四溫度時,表示鍋具200內的水溢出、瓦斯流量不足或瓦斯中斷等原因,使火焰熄滅,因此為了防止瓦斯外洩的問題,則中止提供瓦斯至該加熱裝置20,以保護使用者的生命及財產安全。 In the third embodiment, in steps S150 to S160 In addition, a judging step may be added to determine whether the temperature of the pan 200 is greater than or less than the third temperature when the second gas flow rate is provided. When the temperature of the pan 200 is greater than the third temperature, indicating that there is no moisture in the pan 200, it is determined that the pan 200 is in an air-burning state, and then the gas is supplied to the heating device 20 to avoid the pan 200. Damage or fire. When the temperature of the pot 200 is lowered from the third temperature to a fourth temperature lower than the third temperature, it indicates that the water in the pot 200 overflows, the gas flow is insufficient, or the gas is interrupted, and the flame is extinguished, so In order to prevent the leakage of gas, the supply of gas to the heating device 20 is suspended to protect the life and property of the user.

由於在使用上被加熱物通常由多種食材所組 成,例如煮飯時,被加熱物所包含的食材基本上為米與水,甚至某些時候會再加入其它的食材。為了因應此種情況,在第四實施例中,亦可在步驟S110之前將複數種不同的食材及各該食材所對應的比熱值建立於該記憶體60中,在加熱之前由使用者依據所要使用的食材及比例,透過該輸入單元50選擇該些食材之中的至少二者作為該被加熱物,並透過該輸入單元50設定所選擇的至少二個食材之比例。設定完成後,該運算電路44依據所選擇的食材的比熱值及食材的比例產生一等效比熱值。而於步驟S140中運算電路44以該等效比熱值作為被加熱物的比熱K,代入計算式m=H/(△T×K)計算而得到該被加熱物210的重量,以進行後續的加熱動作之控制。舉例而言,所選擇的食材包括第一食材與第二食材,第一食材比熱值為K1,第二食材比熱值為K2,且二者的比例為A1:A2,A1為第一食材的比例,A2為第二食材的比例,則等效比熱值之計算式為(K1*A1+K2*A2)/(A1+A2)。若為n種食材的混合則等效比熱 值為(K1*A1+K2*A2+…+Kn*An)/(A1+A2+…+An)。 Since the object to be heated is usually composed of a plurality of food materials, for example, when cooking rice, the foodstuff contained in the object to be heated is substantially rice and water, and sometimes other ingredients are added. In order to cope with the situation, in the fourth embodiment, a plurality of different food materials and a specific heat value corresponding to each of the food materials may be established in the memory 60 before the step S110, and the user may At least two of the ingredients are selected as the object to be heated through the input unit 50, and the ratio of the selected at least two ingredients is set by the input unit 50.
