Description

爐火控制裝置Furnace control device

本新型涉及瓦斯爐的爐火控制技術。The new model relates to the fire control technology of a gas stove.

為了避免發生因鍋具空燒所引起的氣爆或火災意外，現有的瓦斯爐的爐頭通常具備一溫度感測器供接觸置放在該爐頭上的一鍋具的底部。當該溫度感測器感測到該鍋具的溫度因發生空燒而達到一上限時，就會驅使一閥關閉，藉以中斷瓦斯的供應而使爐火熄滅。另外，為了避免爐火因故熄滅而發生瓦斯中毒、氣爆等意外，該爐頭也具備一熱電耦，一旦爐火熄滅即無法再對該熱電耦加熱，該熱電耦就會驅使該閥關閉，藉以中斷瓦斯的供應，避免瓦斯外洩。In order to avoid gas explosion or fire accidents caused by empty cooking of the pot, the burner of the existing gas stove usually has a temperature sensor for contacting the bottom of a pot placed on the burner. When the temperature sensor senses that the temperature of the pot has reached an upper limit due to idling, it will drive a valve to close, thereby interrupting the supply of gas and extinguishing the fire. In addition, in order to avoid accidents such as gas poisoning and gas explosion caused by the fire extinguishing for some reason, the burner also has a thermocouple. Once the fire is extinguished, the thermocouple can no longer be heated, and the thermocouple will drive the valve to close , In order to interrupt the gas supply and avoid gas leakage.

上述用於接觸鍋具底部的溫度感測器，原本僅有偵測鍋具是否發生空燒之用途，但目前亦有將它用於其它用途，例如台灣I674379專利揭露利用一溫度感測器來偵測一鍋具的溫度對時間的變化，藉以判斷該鍋具的種類（例如金屬類鍋具、玻璃類鍋具或陶鍋），並依判斷結果進行火力的調節。又例如台灣I626406專利揭露利用一溫度感測器來偵測一鍋具的溫度，藉以判斷該鍋具內的水是否沸騰，並在判斷結果為是時將火力調整為小火。與此類似者，尚有台灣I624628專利。The above-mentioned temperature sensor used to touch the bottom of the pot was originally only used to detect whether the pot is empty, but it is also used for other purposes. For example, the Taiwan I674379 patent discloses the use of a temperature sensor Detect the temperature change of a pot with time to determine the type of the pot (such as metal pots, glass pots or ceramic pots), and adjust the fire power according to the judgment results. For example, the Taiwan I626406 patent discloses the use of a temperature sensor to detect the temperature of a pot, so as to determine whether the water in the pot is boiling, and adjust the fire power to a low fire when the result of the determination is yes. Similar to this, there is still Taiwan I624628 patent.

相對於先前技術，本發明之爐火控制裝置利用偵測鍋具溫度的溫度感測器配合控制閥的設置來控制一爐頭的內、外環火焰的火力表現，藉以提高爐頭使用上的安全性。Compared with the prior art, the stove fire control device of the present invention uses a temperature sensor that detects the temperature of the pot and the setting of a control valve to control the fire performance of the inner and outer ring flames of a stove, thereby improving the use of the stove. safety.

圖1顯示本新型之爐火控制裝置100的一個較佳實施例，其包括一外環控制閥2、一內環控制閥3、一溫度感測器41、一控制電路42及一安全閥5。如圖1及圖2所示，一爐頭1包括用於產生一外環火焰的一外環火焰產生部11及用於產生一內環火焰的一內環火焰產生部12。外環火焰產生部11連接外環控制閥2的一輸出端21，內環火焰產生部12連接內環控制閥3的一輸出端31。外環控制閥2的一輸入端22與內環控制閥3的一輸入端32分別連接安全閥5兩輸出端51。安全閥5的一輸入端52連接一瓦斯開關8的一輸出端81。瓦斯開關8的一輸入端連接一瓦斯源（圖中未示）。當一使用者將瓦斯開關8轉動到一開啟位置時，該瓦斯源的瓦斯就會經由裝置100流入爐頭1。當該使用者將瓦斯開關8轉動到一關閉位置時，該瓦斯源的瓦斯就被阻斷而無法流入裝置100，亦即，無法供應給爐頭1。此外，該使用者還可藉由轉動瓦斯開關8來調整瓦斯的供應量。Figure 1 shows a preferred embodiment of the new type of furnace fire control device 100, which includes an outer loop control valve 2, an inner loop control valve 3, a temperature sensor 41, a control circuit 42 and a safety valve 5 . As shown in FIGS. 1 and 2, a furnace head 1 includes an outer ring flame generating part 11 for generating an outer ring flame and an inner ring flame generating part 12 for generating an inner ring flame. The outer ring flame generating part 11 is connected to an output end 21 of the outer ring control valve 2, and the inner ring flame generating part 12 is connected to an output end 31 of the inner ring control valve 3. An input end 22 of the outer ring control valve 2 and an input end 32 of the inner ring control valve 3 are respectively connected to two output ends 51 of the safety valve 5. An input 52 of the safety valve 5 is connected to an output 81 of a gas switch 8. An input terminal of the gas switch 8 is connected to a gas source (not shown in the figure). When a user turns the gas switch 8 to an open position, the gas from the gas source will flow into the burner 1 through the device 100. When the user turns the gas switch 8 to a closed position, the gas from the gas source is blocked and cannot flow into the device 100, that is, it cannot be supplied to the burner 1. In addition, the user can also adjust the gas supply amount by turning the gas switch 8.

如圖2所示，內環火焰產生部12的一內環進氣管121具有一瓦斯噴頭122及兩開口123，內環控制閥3的輸出端31連接瓦斯噴頭122。來自內環控制閥3的瓦斯由瓦斯噴頭122噴入內環進氣管121，空氣由開口123進入內環進氣管121內，瓦斯與空氣混合成的混合燃氣由內環火焰產生部12的多個內環火孔120噴出，於點火器14點火之後，即形成該內環火焰。As shown in FIG. 2, an inner ring air inlet pipe 121 of the inner ring flame generating part 12 has a gas nozzle 122 and two openings 123, and the output end 31 of the inner ring control valve 3 is connected to the gas nozzle 122. The gas from the inner ring control valve 3 is sprayed into the inner ring intake pipe 121 by the gas nozzle 122, the air enters the inner ring intake pipe 121 through the opening 123, and the mixed gas formed by the gas and air is mixed by the inner ring flame generator 12 A plurality of inner ring fire holes 120 spray out, and the inner ring flame is formed after the igniter 14 is ignited.

外環火焰產生部11的一外環進氣管111具有一瓦斯噴頭112及兩開口113，外環控制閥2的輸出端21連接瓦斯噴頭112。來自外環控制閥2的瓦斯由瓦斯噴頭112噴入外環進氣管111，空氣由開口113進入外環進氣管111內，瓦斯與空氣混合成的混合燃氣由外環火焰產生部11的多個外環火孔110噴出，於點火器14點火之後，即形成該外環火焰。如一般所知，該外環火焰的火力係大於該內環火焰。An outer ring air intake pipe 111 of the outer ring flame generating part 11 has a gas nozzle 112 and two openings 113, and the output end 21 of the outer ring control valve 2 is connected to the gas nozzle 112. The gas from the outer ring control valve 2 is sprayed into the outer ring intake pipe 111 by the gas nozzle 112, the air enters the outer ring intake pipe 111 through the opening 113, and the mixed gas formed by the mixture of gas and air is discharged from the outer ring flame generator 11 A plurality of outer ring fire holes 110 spray out, and the outer ring flame is formed after the igniter 14 is ignited. As generally known, the firepower of the outer flame is greater than that of the inner flame.

如圖1及2所示，溫度感測器41用於感測放置在爐頭1上的一鍋具7的溫度，在此實施例中，溫度感測器41位於內環火焰產生部12的中央，當鍋具7置放於爐頭1上時，溫度感測器41的頂端會接觸到鍋具7的一底面，藉以感測鍋具7的溫度。As shown in Figures 1 and 2, the temperature sensor 41 is used to sense the temperature of a pot 7 placed on the furnace head 1. In this embodiment, the temperature sensor 41 is located at the inner ring flame generating portion 12 In the center, when the pot 7 is placed on the stove 1, the top of the temperature sensor 41 will touch a bottom surface of the pot 7 to sense the temperature of the pot 7.

控制電路42耦接溫度感測器41、外環控制閥2與內環控制閥3，並能根據溫度感測器41的感測結果控制外環控制閥2與內環控制閥3，藉以控制進入外環火焰產生部11與內環火焰產生部12的瓦斯量，進而控制該外環火焰與該內環火焰的火力。The control circuit 42 is coupled to the temperature sensor 41, the outer loop control valve 2 and the inner loop control valve 3, and can control the outer loop control valve 2 and the inner loop control valve 3 according to the sensing result of the temperature sensor 41, thereby controlling The amount of gas entering the outer ring flame generating portion 11 and the inner ring flame generating portion 12 controls the firepower of the outer ring flame and the inner ring flame.

在此實施例中，外環控制閥2及安全閥5都能在一全開狀態與一全關狀態之間切換。內環控制閥3則能在一全開狀態與一小開狀態之間切換。In this embodiment, both the outer loop control valve 2 and the safety valve 5 can be switched between a fully open state and a fully closed state. The inner loop control valve 3 can switch between a fully open state and a small open state.

在正常煮食況狀下（例如煎、炒或炸），外環控制閥2、內環控制閥3與安全閥5在一開始時是處於一全開狀態，使得外環火焰產生部11產生該外環火焰，內環火焰產生部12產生該內環火焰，這表示爐頭1正在以大火對鍋具7加熱，藉以提昇鍋具7的溫度。當控制電路42根據溫度感測器41的感測結果判斷鍋具7的溫度已上昇到高於一第一門檻值（例如260℃）時，就令外環控制閥2進入一全關狀態及令內環控制閥3進入一小開狀態，使得該外環火焰熄滅，該內環火焰變小，這表示爐頭1的爐火已從大火轉變成小火，故鍋具7的溫度將逐漸下降。當控制電路42根據溫度感測器41的感測結果判斷鍋具7的溫度已下降到低於一第二門檻值（例如230℃）時，就令外環控制閥2進入該全開狀態及令內環控制閥3進入該全開狀態，如上所述，爐頭1的爐火此時會從小火轉變成大火，使得鍋具7的溫度逐漸提昇。一旦鍋具7的溫度上昇到高於該第一門檻值，如上所述，爐頭1的爐火就會從大火轉變成小火，以使鍋具7的溫度下降。一旦鍋具7的溫度下降到低於該第二門檻值，如上所述，爐頭1的爐火又會從小火轉變成大火，以此類推，不再贅述。Under normal cooking conditions (such as frying, frying or frying), the outer ring control valve 2, the inner ring control valve 3, and the safety valve 5 are in a fully open state at the beginning, so that the outer ring flame generating part 11 generates the The outer ring flame and the inner ring flame generating part 12 generate the inner ring flame, which indicates that the burner 1 is heating the pot 7 with a high fire, thereby increasing the temperature of the pot 7. When the control circuit 42 determines according to the sensing result of the temperature sensor 41 that the temperature of the pot 7 has risen above a first threshold (for example, 260°C), the outer loop control valve 2 enters a fully closed state and Let the inner ring control valve 3 enter a small open state, so that the outer ring flame is extinguished, and the inner ring flame becomes smaller. This means that the fire of the burner 1 has changed from a large fire to a small fire, so the temperature of the pot 7 will gradually decline. When the control circuit 42 determines according to the sensing result of the temperature sensor 41 that the temperature of the pot 7 has fallen below a second threshold value (for example, 230°C), it makes the outer loop control valve 2 enter the fully open state and makes The inner ring control valve 3 enters the fully open state. As described above, the fire of the stove head 1 will change from a low fire to a high fire at this time, so that the temperature of the pot 7 gradually increases. Once the temperature of the pot 7 rises above the first threshold, as described above, the fire of the stove head 1 will change from a high fire to a low fire, so that the temperature of the pot 7 will drop. Once the temperature of the pot 7 drops below the second threshold value, as described above, the fire of the stove head 1 will change from a small fire to a high fire, and so on, and will not be repeated.

由上述說明可知，在本新型之爐火控制裝置100的控制下，爐頭1的爐火在鍋具7的溫度一上昇到高於該第一門檻值時就會變小，故可將鍋具7內的油溫抑制在該第一門檻值之下，避免出現油溫過高引起油品自燃的危險情況。It can be seen from the above description that under the control of the stove fire control device 100 of the present invention, the stove fire of the stove head 1 will decrease when the temperature of the pot 7 rises above the first threshold, so the pot can be reduced The oil temperature in the tool 7 is suppressed below the first threshold to avoid the danger of spontaneous combustion of the oil due to excessive oil temperature.

較佳地，控制電路42在首次判斷出鍋具7的溫度高於該第一門檻值時就開始計時一段預設時間（例如30分鐘），並在計時結束時令安全閥5進入一全關狀態，使得該外環火焰與該內環火焰均熄滅，且瓦斯無外洩之虞。這表示，當爐頭1的爐火進行上述的大、小火反覆切換運作長達該預設時間之後就自動熄火，以策安全。Preferably, when the control circuit 42 first determines that the temperature of the pot 7 is higher than the first threshold value, it starts timing for a preset period of time (for example, 30 minutes), and when the timing ends, the safety valve 5 is fully closed. State, so that the outer ring flame and the inner ring flame are both extinguished, and there is no risk of gas leakage. This means that when the furnace head 1 performs the above-mentioned repeated switching operation between large and small fires for the preset time, it will automatically turn off for safety.

較佳地，當控制電路42根據溫度感測器41的感測結果判斷鍋具7的溫度已上昇到高於一第三門檻值（例如300℃）時，表示通過上述的大、小火反覆切換運作仍無法抑制鍋具7內的油溫竄升，此時控制電路42立即令安全閥5進入該全關狀態，使得該外環火焰與該內環火焰均熄滅，確保鍋具7內的油溫不再昇高，杜絕油溫過高引起油品自燃的危險情況。Preferably, when the control circuit 42 determines according to the sensing result of the temperature sensor 41 that the temperature of the pot 7 has risen above a third threshold (for example, 300°C), it means that the above-mentioned high and low fires are repeated The switching operation still cannot suppress the oil temperature rise in the pot 7. At this time, the control circuit 42 immediately causes the safety valve 5 to enter the fully closed state, so that both the outer ring flame and the inner ring flame are extinguished, ensuring that the oil temperature in the pot 7 The oil temperature will no longer rise, and the dangerous situation of spontaneous combustion of oil caused by excessive oil temperature will be eliminated.

較佳地，當控制電路42根據溫度感測器41的感測結果判斷鍋具7的溫度在一溫昇期間內（例如從75℃上昇至130℃之期間內）的每秒溫度變化幅度有長達一段預設時間（例如4分鐘）以上均小於一預設值（例如1.5℃）時，就表示鍋具7內有水，之後，當控制電路42根據溫度感測器41的感測結果判斷鍋具7的溫度已竄升到一空燒門檻值（例如170℃）時，就表示鍋具7已在空燒，此時控制電路42就令該令安全閥5進入該全關狀態，使得該外環火焰與該內環火焰均熄滅，且瓦斯無外洩之虞。Preferably, when the control circuit 42 determines according to the sensing result of the temperature sensor 41 that the temperature of the pot 7 has a temperature change range per second during a temperature rise period (for example, during a rise from 75°C to 130°C) When a predetermined period of time (for example, 4 minutes) or more is less than a predetermined value (for example, 1.5°C), it means that there is water in the pot 7. Then, when the control circuit 42 is based on the sensing result of the temperature sensor 41 When it is judged that the temperature of the pot 7 has risen to the threshold value of empty firing (for example, 170°C), it means that the pot 7 is already firing. At this time, the control circuit 42 makes the safety valve 5 enter the fully closed state, so that Both the outer ring flame and the inner ring flame are extinguished, and there is no risk of gas leakage.

較佳地，在鍋具7受該外環火焰及該內環火焰加熱而使其溫度上昇之期間，當控制電路42根據溫度感測器41的感測結果判斷鍋具7的溫度上昇到一第一預設值（例如160℃）時就進行一抑制運作，該抑制運作包括令外環控制閥2進入該全關狀態及令內環控制閥3進入該小開狀態，此時，如上所述，爐頭1的爐火變成小火，使得鍋具7的溫度將逐漸下降。該抑制運作還包括在一段預設時間（例如20秒）之後，再令外環控制閥2進入該全開狀態及令內環控制閥3進入該全開狀態，此時，如上所述，爐頭1的爐火變成大火，使得鍋具7的溫度將逐漸上昇。簡言之，藉由該抑制運作，可在鍋具7溫度上昇至該第一預設值時抑制一下鍋具7的溫度上昇，避免鍋具7的溫度竄升過快。Preferably, while the temperature of the pot 7 is increased by the outer flame and the inner flame, when the control circuit 42 determines that the temperature of the pot 7 has risen to a level according to the sensing result of the temperature sensor 41 At the first preset value (for example, 160°C), a suppression operation is performed. The suppression operation includes making the outer loop control valve 2 enter the fully closed state and the inner loop control valve 3 entering the small open state. At this time, as described above As mentioned, the fire of the stove head 1 becomes a low fire, so that the temperature of the pot 7 will gradually drop. The suppression operation also includes after a preset period of time (for example, 20 seconds), the outer loop control valve 2 is then brought into the fully open state and the inner loop control valve 3 is brought into the fully open state. At this time, as described above, the burner 1 The stove fire turns into a big fire, so that the temperature of the pot 7 will gradually rise. In short, with the suppression operation, the temperature rise of the pot 7 can be suppressed when the temperature of the pot 7 rises to the first preset value, so as to prevent the temperature of the pot 7 from rising too fast.

較佳地，當控制電路42根據溫度感測器41的感測結果判斷鍋具7的溫度上昇到一第二預設值（例如180℃）時，再進行一次該抑制運作，藉以抑制一下鍋具7的溫度上昇，避免鍋具7的溫度竄升過快。Preferably, when the control circuit 42 determines that the temperature of the pot 7 has risen to a second preset value (for example, 180° C.) according to the sensing result of the temperature sensor 41, the suppression operation is performed again to suppress the pot. The temperature of the pot 7 rises to prevent the temperature of the pot 7 from rising too fast.

較佳地，當控制電路42根據溫度感測器41的感測結果判斷鍋具7的溫度上昇到一第三預設值（例如200℃）時，又進行一次該抑制運作，藉以抑制一下鍋具7的溫度上昇，避免鍋具7的溫度竄升過快。Preferably, when the control circuit 42 determines that the temperature of the pot 7 has risen to a third preset value (for example, 200° C.) according to the sensing result of the temperature sensor 41, the suppression operation is performed again to suppress the pot. The temperature of the pot 7 rises to prevent the temperature of the pot 7 from rising too fast.

若想要再抑制一或多次鍋具7的溫度上昇，只需選擇一或多個預設值，並使控制電路42在鍋具7的溫度上昇到所選擇的預設值時就進行一次該抑制運作即可。If you want to suppress the temperature rise of the pot 7 for one or more times, you only need to select one or more preset values, and make the control circuit 42 do it once when the temperature of the pot 7 rises to the selected preset value This suppression works.

此外，本新型之爐火控制裝置100可再包括一熱電耦6 ，控制電路42耦接熱電耦6。熱電耦6由該內環火焰加熱，一旦該內環火焰熄滅，熱電耦6就會發出訊號通知控制電路42令安全閥5進入該全關狀態，避免瓦斯外洩。In addition, the furnace fire control device 100 of the present invention may further include a thermocouple 6, and the control circuit 42 is coupled to the thermocouple 6.
