Description
本發明是有關於一種排油煙機系統及其控制方法,且尤其是有關一種可自動調整排煙段數的排油煙機系統及其控制方法。 The invention relates to a range hood system and a control method thereof, and in particular to a range hood system and a control method thereof that can automatically adjust the number of smoke exhaust sections.
一般而言,由於烹煮時所產生的油煙容易對人體產生危害,廚房中多設有排油煙機,透過排油煙機之作動,可將油煙排至戶外。 Generally speaking, because the cooking fume is easily harmful to the human body, there are many range hoods in the kitchen, and the cooking fume can be exhausted to the outdoors through the action of the range hood.
習知之排油煙機多設有開關以切換排煙段數,由使用者依使用時的狀況按壓開關進行排煙段數的調整。然而,煮食時雙手需分別控制鍋鏟,而不利使用者再利用手動方式切換排煙段數。 Conventional range hoods are often equipped with switches to switch the number of smoke exhaust sections, and the user presses the switch to adjust the number of smoke exhaust sections according to the conditions of use. However, when cooking, both hands need to control the spatula separately, which is unfavorable for the user to manually switch the number of smoke exhaust sections.
為了解決此一問題,有業者發展出可自動調整排煙段數的排油煙機,其透過偵測油煙溫度來自動調整排煙段數,但空氣中的溫度受到多種因素影響,並非全由油煙造成,故此種自動調整排煙段數的方式,並無法針對真實的油煙狀況進行調整,而有其限制存在。 In order to solve this problem, some industry hoods have developed a range hood that can automatically adjust the number of smoke-exhaust sections. It automatically adjusts the number of smoke-exhaust sections by detecting the temperature of the oil fume. However, the temperature in the air is affected by many factors, not all of it.

請參閱第1圖,其中第1圖繪示依照本發明一實施例之一種排油煙機系統100的架構示意圖。排油煙機系統100包含一排油煙機110、一攝影機120及一控制器140,排油煙機110包含一馬達111;攝影機120用以取得一影像;控制器140訊號連接排油煙機110及攝影機120且包含一影像分析模組141及一轉速控制模組142,影像分析模組141分析影像中的一使用者手勢及一油煙中的至少一者,以提供一轉速指令;轉速控制模組142訊號連接馬達111,依轉速指令調整馬達111之轉速。
Please refer to FIG. 1. FIG. 1 is a schematic structural diagram of a
藉此,可透過攝影機120偵測使用者的手部動作及煮食時油煙狀況的其中之一,對應調節馬達111的轉速
以改變排油煙機110的排煙段數,具有使用方便之優點。後面將詳述排油煙機系統100的細節。
In this way, one of the user's hand movement and the oily smoke condition during cooking can be detected through the
排油煙機110內部設有馬達111,利用馬達111轉動可將煮食時產生之油煙吸入排油煙機110的內部,再藉由排煙管將油煙排除。控制器140可設於排油煙機110的內部,控制器140的轉速控制模組142可啟閉馬達111並調整馬達111的轉速,以改變排油煙機110的排煙段數。排油煙機110的結構及原理為已知且非本案之重點或技術改良,不再贅述。
The
攝影機120可架設於一廚房環境中的任一位置,而能拍攝廚房環境的油煙或使用者以取得一影像。攝影機120的數目可以是一個或多個,且攝影機120所拍攝的影像可以是採用有線或無線方式傳送到控制器140,由控制器140接收並分析。上述的影像可以是持續錄製產生之連續畫面,不以單一靜止畫面為限。
The
由於攝影機120拍攝的影像中會包含油煙或使用者,影像分析模組141可依據油煙或使用者手勢中任一者或兩者的狀況,發出轉速指令,使轉速控制模組142調整馬達111的轉速。
Since the image captured by the
在一實施例中,影像分析模組分析影像中的油煙,其可以依據影像中畫面內油煙所佔之比例、濃度、或是連續畫面下油煙之流動速度,來判定影像中油煙之大小,而對應給予一轉速指令,例如油煙可分為大、中、小三類,分別給予三個轉速指令以使馬達操作於大、中、小三個轉速, 或是經相關運算後,自動將馬達設定在最適合的出力段速,包含上述但不以此為限。 In one embodiment, the image analysis module analyzes the oil smoke in the image, which can determine the size of the oil smoke in the image according to the proportion and concentration of the oil smoke in the frame of the image, or the flow speed of the oil smoke in the continuous frame, and Correspondingly give a speed command. For example, oil fume can be divided into three types: large, medium, and small. Three speed commands are given to make the motor operate at three speeds: large, medium and small. Or after related calculations, the motor is automatically set at the most suitable output speed, including the above but not limited to this.
在一實施例中,影像分析模組可分析影像中的使用者手勢來發出對應之轉速指令,例如判斷使用者手勢的一揮動方向,如,當手由右而左揮時,馬達增速,反之則馬達降速,而增速之揮動方向亦可以改為由左而右、由上而下或由下而上等。又例如,可判斷使用者手勢的一手指數目來發出對應之轉速指令,如一根手指代表要一速,二根就二速,依此類推,五指全開就以最高速執行,當使用者手勢為拳頭時,代表關機,並進入後清掃模式,包含上述但不以此為限。 In one embodiment, the image analysis module can analyze the user's gesture in the image to issue a corresponding rotation speed command, for example, to determine a direction of the user's gesture, for example, when the hand is swiped from the right to the left, the motor speeds up. On the contrary, the speed of the motor will decrease, and the direction of increasing speed can be changed from left to right, top to bottom or bottom to top. For another example, the number of fingers in the user's gesture can be judged to issue the corresponding rotation speed command. For example, one finger means one speed, two fingers means two speed, and so on, all five fingers are opened at the highest speed. When the user gesture is When fisting, it means shutting down and entering the post-cleaning mode, including the above but not limited to this.
若影像分析模組可同時依據油煙及使用者手勢來調整馬達的轉速時,可以是先依據影像中的油煙的狀況先給定一轉速指令,馬達先依此轉速指令運轉,而由使用者依其習慣進行調整,此時可以再以使用者手勢發出另一轉速指令來調整馬達轉速,而能更符合使用者需求。 If the image analysis module can adjust the rotation speed of the motor according to the oil smoke and the user's gestures at the same time, it can first give a rotation speed command according to the oil smoke in the image, and the motor runs according to the rotation speed command. It is accustomed to make adjustments. At this time, another speed command can be issued by the user's gesture to adjust the motor speed, which can better meet the needs of the user.
較佳地,影像分析模組141可分析並校正影像中的一油煙,以產生轉速指令。由於廚房環境中會產生油煙,油煙容易造成攝影機120的鏡頭污染,因此可透過影像分析模組141的校正,使所分析到的油煙符合實際狀況。舉例而言,在初始安裝攝影機120於廚房環境中時,即保存一初始影像,而在排油煙機110每次運作時,取得一第一影像,以該第一影像與初始影像比對,而能進行差異補償或背影值調整等,以避免鏡頭髒汙造成之判斷失準。
Preferably, the
於第1圖的實施例中,控制器140可更包含一無線通訊模組143訊號連接一煮食爐200,影像分析模組141分析油煙,以提供一爐力指令,無線通訊模組143將爐力指令傳送予煮食爐200。
In the embodiment of FIG. 1, the
舉例而言,影像分析模組141可分析油煙的流動速度、濃度或顏色,其經相關運算後,若判定是在非正常煮食狀態下所產生之油煙,無線通訊模組143將會傳送爐力指令,通知煮食爐200關閉瓦斯,以避免空燒或是不正常煮食造成之危險。更佳地,此時排油煙機110會以最高速運作,以加快油煙的排除動作。
For example, the
在一實施例中,煮食爐的作動亦可以和排油煙機之開啟與出力段速相關。例如,當煮食爐開啟時,排油煙機亦同時開啟,且排油煙機的出力段速與煮食爐的火力或煮食強度對應,例如大火或高煮食強度對應排油煙機高速運轉等,且不影響排油煙機依據油煙或使用者手勢調整排煙段數的功能。 In one embodiment, the action of the cooking stove can also be related to the opening and output speed of the range hood. For example, when the cooking stove is turned on, the range hood is also turned on at the same time, and the output speed of the range hood corresponds to the fire power or cooking intensity of the cooking stove. For example, high fire or high cooking intensity corresponds to the high-speed operation of the range hood, etc. , And does not affect the function of the range hood to adjust the number of smoke sections according to the lampblack or user gestures.
此外,排油煙機系統100可更包含一照明裝置150,其訊號連接控制器140且受控制器140啟閉。排油煙機系統100可再設置感應裝置160,其訊號連接控制器140,當感應裝置160感應有使用者時,傳送訊號給控制器140,以對應開啟照明裝置150,產生迎賓效果。
In addition, the
又,排油煙機系統100可更包含一霧化噴出裝置130,其用以噴出一霧化液體,霧化噴出裝置130訊號連接控制器140且受控制器140啟閉。當排油煙機系統100進
入清掃時,可設定讓霧化噴出裝置130噴出香精或除味劑等,淨化廚房環境,以降低煮食後所產生之油煙味道,包含但不以此為限。
In addition, the
