The range hood 1 with the thermal image detection function of this embodiment can pass a wide-area detection of the temperature of the heat source, and can relatively provide a friendly operation with intelligent control. In one embodiment, the range hood 1 may include a thermal image detection circuit 10, a control circuit 12 and an exhaust circuit 14. The thermal image detection circuit 10 is electrically connected to the control circuit 12, The control circuit 12 is electrically connected to the exhaust circuit 14. The thermal image detection circuit 10 can detect the temperature of the heat source generated by the gas furnace, and the temperature detection range can cover the range of the heating area provided by the gas furnace. In one embodiment, the thermal image detection circuit 10 has a plurality of thermal image detectors 101, and the thermal image detector 101 is, for example, shown in FIG. 2 and arranged directly above the gas furnace in an array plane distribution. This wide-area setting method can effectively detect various heat source temperature changes in each heating area when the gas furnace is used. However, the present invention is not limited to the number and distribution of the thermal image detectors 101 as long as the heating temperature change of the gas furnace can be successfully detected. Here, the thermal image detector 101 can convert the intensity of thermal radiation emitted from the surface of the object to be detected into thermal images with relatively different temperature distributions. In one embodiment, the thermal image detector 101 can be infrared thermal Image detector, but the invention is not limited to this.
控制電路12根據熱影像偵測電路10的偵測結果,而可以相對提供智能的人性化操作控制。在一實施例中,控制電路12可以根據熱影像偵測電路10的偵測結果,進而得知瓦斯爐的使用狀況,例如有無烹煮或是烹煮時使用的火力大小等各種可能使用狀況。而當控制電路10得知上述瓦斯爐的使用狀況時,可以相對應控制排油煙機1自動啟動運轉或自動停止運轉。在一實施例中,當控制電路12得知開始烹煮時可以輸出驅動信號給排氣電路14,以使排氣電路14開始運轉。在一實施例中,當控制電路12得知烹煮時的高溫持續施上升而有危害鍋具時,控制電路12還可以對相關人員示警或是無線控制火斯爐關閉。在一實施例中,當控制電路12得知結束烹煮時含可以輸出驅動信號給排氣電路14,以使排氣電路14停止運轉。 The control circuit 12 can provide intelligent humanized operation control relatively according to the detection result of the thermal image detection circuit 10. In one embodiment, the control circuit 12 can learn the use status of the gas stove according to the detection result of the thermal image detection circuit 10, such as whether there are various possible use conditions such as cooking or the amount of firepower used during cooking. When the control circuit 10 learns the use condition of the gas furnace, it can correspondingly control the automatic start operation or automatic stop operation of the range hood 1. In an embodiment, when the control circuit 12 learns that cooking is started, it may output a driving signal to the exhaust circuit 14 so that the exhaust circuit 14 starts to operate. In an embodiment, when the control circuit 12 learns that the high temperature during cooking continues to increase and harms the cookware, the control circuit 12 may also alert the relevant personnel or wirelessly control the stove to shut down. In an embodiment, when the control circuit 12 learns that the cooking is finished, the control circuit 12 may output a driving signal to the exhaust circuit 14 to stop the exhaust circuit 14 from operating.
排氣電路14可以例如包括驅動電路141及風扇電路143。驅動電路141電性連接風扇電路143,並根據控制電路12輸出的驅動信號對風扇電路143進行控制。在一實施例中,當驅動電路141收到代表啟動的驅動信號時,則控制風扇電路143啟動運轉,進而可以讓排油煙機1開始進行排煙。而當驅動電路141收到代表 停止的驅動信號時,則控制風扇電路143停止運轉,進而讓排油煙機1關閉停止排煙。另外值得注意的是,控制電路12還可以進一步提供不同轉速的驅動信號,以透過驅動電路141相對控制風扇電路143以不同的馬達轉速運轉。 The exhaust circuit 14 may include, for example, a driving circuit 141 and a fan circuit 143. The driving circuit 141 is electrically connected to the fan circuit 143 and controls the fan circuit 143 according to a driving signal output by the control circuit 12. In an embodiment, when the driving circuit 141 receives a driving signal representative of starting, the fan circuit 143 is controlled to start running, so that the fume hood 1 can start to exhaust smoke. And when the driving circuit 141 receives a representative When the driving signal is stopped, the fan circuit 143 is controlled to stop the operation, and the exhaust hood 1 is turned off to stop exhausting the smoke. It is also worth noting that the control circuit 12 can further provide driving signals with different rotation speeds to control the fan circuit 143 to operate at different motor rotation speeds through the driving circuit 141.
值得注意的是,在一實施例中控制電路12透過數個取樣週期以讀取熱影像偵測電路10偵測結果的多個溫度平面分佈數據,並對多個溫度平面分佈數據進行統計及分析的相關計算,即可得知目前瓦斯爐的各種動靜態的烹煮行為模式。舉例來說,在單一個取樣週期是指控制電路12同時取得所有熱影像偵測器101的所有偵測結果,即每一個熱影像偵測器101都會輸出溫度偵測數值,而此溫度偵測數值即可反應出此熱影像偵測器101對應偵測位置的熱源影像溫度變化。舉例來說,對於熱影像偵測電路10而言其所有熱影像偵測器101輸出構成的溫度平面分佈數據可以例如圖3A及圖3B所示。以圖3A中的熱影像而言,其中熱點301即代表某一熱影像偵測器101的偵測結果,而此熱點301的顏色深淺或是熱點的大小可隨熱源溫度對應變化。經由對比圖3A及圖3B即可得知,圖3B的關於熱點301分佈區域及密度均比圖3A更明顯。故對於控制電路12而言透過分析及計算圖3A及圖3B中熱影像的相關數據即可得知瓦斯爐在烹煮,且溫度隨著烹煮時間例如由圖3A往圖3B變化而呈現升高。 It is worth noting that, in an embodiment, the control circuit 12 reads multiple temperature plane distribution data of the detection result of the thermal image detection circuit 10 through several sampling cycles, and performs statistics and analysis on the multiple temperature plane distribution data. Related calculations, you can know the current dynamic and static cooking behavior of gas stoves. For example, in a single sampling cycle, the control circuit 12 obtains all the detection results of all the thermal image detectors 101 at the same time, that is, each thermal image detector 101 outputs a temperature detection value, and the temperature detection The numerical value can reflect the temperature change of the heat source image corresponding to the detection position of the thermal image detector 101. For example, for the thermal image detection circuit 10, the temperature plane distribution data formed by the output of all the thermal image detectors 101 can be shown in FIG. 3A and FIG. 3B, for example. In terms of the thermal image in FIG. 3A, the hot spot 301 represents the detection result of a certain thermal image detector 101, and the color depth of the hot spot 301 or the size of the hot spot may change correspondingly with the temperature of the heat source. It can be seen by comparing FIG. 3A and FIG. 3B that the distribution area and density of the hot spots 301 in FIG. 3B are more obvious than those in FIG. 3A. Therefore, for the control circuit 12, by analyzing and calculating the relevant data of the thermal images in FIG. 3A and FIG. 3B, it can be known that the gas stove is cooking, and the temperature rises as the cooking time changes from FIG. 3A to FIG. 3B. high.
在一實施例中,控制電路12還可進一步包括慢速啟動電路121、快速啟動電路123、高溫保護電路125及自動關閉電路127。其中的慢速啟動電路121及快速啟動電路123均是用來判斷何時啟動排氣電路14的運轉。慢速啟動電路121可以例如是針對瓦斯爐小火烹煮的使用狀況進行偵測。快速啟動電路123可以例如是針對瓦斯爐大火烹煮的使用狀況進行偵測。高溫保護電路125則是於排氣電路14啟動運轉後,判斷此時在瓦斯爐上供烹煮的鍋具有無產生高溫,並可以根據此判斷結果決定是否輸出提示信息。 自動關閉電路127則是於排氣電路14啟動運轉後,判斷瓦斯爐上是否要停止烹煮,並可以根據此判斷結果決定是否控制排氣電路14停止運轉。上述控制電路12中的各電路的判斷處理方式僅是舉例說明,本發明並不以此為限。 In one embodiment, the control circuit 12 may further include a slow start circuit 121, a fast start circuit 123, a high temperature protection circuit 125, and an automatic shutdown circuit 127. The slow start circuit 121 and the fast start circuit 123 are both used to determine when to start the operation of the exhaust circuit 14. The slow-start circuit 121 may detect, for example, a use condition of a low-temperature cooking of a gas stove. The quick-start circuit 123 may detect, for example, the use condition of the gas stove cooking. After the high-temperature protection circuit 125 starts to operate, the high-temperature protection circuit 125 determines whether or not the cooking pot on the gas stove has generated high temperature at this time, and can determine whether to output the prompt information according to the determination result. The automatic shutdown circuit 127 determines whether to stop cooking on the gas stove after the exhaust circuit 14 is started, and can determine whether to control the exhaust circuit 14 to stop operation based on the determination result. The determination processing method of each circuit in the control circuit 12 is only an example, and the present invention is not limited thereto.
慢速啟動電路121在本實施例如是以第一取樣週期取得熱影像偵測電路10的第一偵測結果,並於該第一偵測結果符合慢速啟動條件時,慢速啟動電路121啟動排氣電路14運轉。舉例來說,第一取樣週期例如是包括有多個取樣週期,因此第一偵測結果可以有多筆溫度平面分佈數據的取樣資料,而慢速啟動條件則例如是設定瓦斯爐以小火烹煮時對應的預設熱源密度驅勢變化。故當慢速啟動電路121對第一偵測結果進行數值的統計及分析的計算後,若第一偵測結果符合預設熱源密度驅勢變化,則慢速啟動電路121可以控制排氣電路141啟動運轉。 In this embodiment, the slow start circuit 121 obtains the first detection result of the thermal image detection circuit 10 at a first sampling period, and when the first detection result meets the slow start condition, the slow start circuit 121 starts. The exhaust circuit 14 operates. For example, the first sampling period includes, for example, multiple sampling periods, so the first detection result may include multiple sampling data of temperature plane distribution data, and the slow start condition is, for example, setting the gas stove to cook on low fire. The corresponding preset heat source density drives the change during cooking. Therefore, after the slow start circuit 121 performs numerical statistics and analysis calculations on the first detection result, if the first detection result conforms to the preset heat source density driving force change, the slow start circuit 121 can control the exhaust circuit 141 Start running.
快速啟動電路123以第二取樣週期取得熱影像偵測電路10的第二偵測結果,並於第二偵測結果符合快速啟動條件時,快速啟動電路123啟動排氣電路14運轉。舉例來說,第二取樣週期例如是單一取樣週期,因此第二偵測結果為單筆溫度平面分佈數據的取樣資料,而快速啟動條件則例如是預設高溫啟動值。故當快速啟動電路123認定第二偵測結果中的溫度平面分佈數據中前M點溫度最高的溫度偵測值的高溫平均值等於大於預設高溫啟動值時,則快速啟動電路123可以控制排氣電路14啟動運轉。由於快速啟動電路123僅需判斷單一取樣週期的單筆取樣資料遠少於慢速啟動電路121需判斷多個取樣週期的多筆取樣資料,因此快速啟動電路123啟動排氣電路14所需的判斷時間遠比慢速啟動電路121短,故具有快速啟動效果。 The quick start circuit 123 obtains the second detection result of the thermal image detection circuit 10 at a second sampling period, and when the second detection result meets the quick start condition, the quick start circuit 123 starts the exhaust circuit 14 to operate. For example, the second sampling period is, for example, a single sampling period, so the second detection result is sampling data of a single temperature plane distribution data, and the fast start condition is, for example, a preset high temperature start value. Therefore, when the fast-start circuit 123 determines that the high-temperature average value of the highest temperature detection value of the first M point temperature in the temperature plane distribution data in the second detection result is equal to or greater than a preset high-temperature start value, the fast-start circuit 123 can control the discharge The gas circuit 14 is started. Since the fast start circuit 123 only needs to determine a single sampling data of a single sampling period is far less than the slow start circuit 121 needs to determine multiple sampling data of multiple sampling periods, the judgment required by the fast start circuit 123 to start the exhaust circuit 14 The time is much shorter than the slow start circuit 121, so it has a fast start effect.
高溫保護電路125於排氣電路14啟動後,根據熱影像偵測電路10的偵測結果符合一高溫保護條件時,輸出一提示信息,以使人員或瓦斯爐可以根據提示信息停止加熱運作。舉例來說,其中 高溫符合條件為溫度平面分佈數據中前N點溫度最高的溫度偵測值的一高溫平均值符合一異常高溫值,或是高溫符合條件為多筆連續溫度平面分佈數據中的每一筆最高溫度值之間相互構成的斜率符合一預設上升斜率值。 After the high-temperature protection circuit 125 is activated, when the detection result of the thermal image detection circuit 10 meets a high-temperature protection condition after the exhaust circuit 14 is activated, it outputs a prompt message so that a person or a gas furnace can stop the heating operation according to the prompt information. For example, where The high temperature compliance condition is the highest temperature detection value of the highest temperature of the first N points in the temperature plane distribution data. An high temperature average value corresponds to an abnormal high temperature value, or the high temperature compliance condition is each highest temperature value in multiple continuous temperature plane distribution data. The mutually constituted slopes conform to a preset rising slope value.
自動關閉電路127於排氣電路14啟動後,根據熱影像偵測電路10的偵測結果符合一關閉條件時,控制排氣電路14以一慢速轉速運轉一預設時間後進行關閉,或是直接關閉,本發明對此並不限制。舉例來說,關閉條件為多筆連續溫度平面分佈數據中的每一筆最高溫度值之間構成的斜率符合一預設下降斜率值。 After the exhaust circuit 14 is activated, the automatic shutdown circuit 127 controls the exhaust circuit 14 to run at a slow speed for a preset time according to the detection result of the thermal image detection circuit 10 when it meets a shutdown condition, or Close directly, the invention is not limited to this. For example, the closing condition is that a slope formed between each of the highest temperature values in a plurality of continuous temperature plane distribution data meets a preset falling slope value.
