Description
本創作係有關一種排氣裝置,尤指一種可有效防止油煙污染物洩漏,以適用於工廠、實驗室及廚房者。This creation relates to an exhaust device, especially one that can effectively prevent the leakage of soot pollutants for use in factories, laboratories and kitchens.
「傳統型排油煙機」與一般用於作業場所的頂吸式吸氣罩沒有太大差別。此類排油煙機之突緣可能是平板狀、往下拱的遮棚形或箱形,而吸氣口則可能是圓形、方形、矩形或長條形。此類排油煙機在吸氣時,空氣與污染物會由突緣之周緣流入氣罩下方,進入吸氣口,再經由導管排至室外。其中,接近吸氣口位置之空氣流速較大,遠離吸氣口位置之空氣流速會隨著離開吸氣口之距離增加而快速下降。因此,在吸氣口下方很短的距離內,空氣往上的速度即已變得很小,使得向上的抽吸力不足,極容易受到來自人員走動、風扇或冷氣運轉等擾動氣流的影響,讓油煙或污染物隨著擾動氣流的流動而逸散。The "traditional range hood" is not much different from the top suction hood used in the workplace. The flange of such a range hood may be a flat, downwardly arched or box-shaped shape, while the suction port may be round, square, rectangular or elongated. When such a range hood is inhaled, air and contaminants will flow from under the rim to the underside of the hood, into the suction port, and then through the conduit to the outside. Among them, the air flow rate near the position of the suction port is large, and the air flow rate away from the position of the suction port will rapidly decrease as the distance from the suction port increases. Therefore, within a short distance below the suction port, the speed of the air upwards has become small, so that the upward suction force is insufficient, and it is highly susceptible to disturbance airflow from the movement of people, fans or air-conditioning operations. Allows soot or contaminants to escape as the flow of disturbed air flows.
當上述排油煙機使用在會產生高溫氣體的環境中時,雖然會因為爐火之高溫而產生較大之浮力效應,使得上升氣流之速度增加,但由於高溫所引起之紊流擴散及擴張效應,則會讓油煙污染物很容易由排油煙機之前、後方與側邊向外散逸。因此,一般之排油煙機常會加大吸力以提升吸氣量,但是,此種方式不但會增加噪音、浪費能源,且無法完全杜絕 洩漏之現象。When the above-mentioned range hood is used in an environment that generates high-temperature gas, although a large buoyancy effect is generated due to the high temperature of the fire, the velocity of the ascending airflow is increased, but the turbulent diffusion and expansion effect due to high temperature It will make the soot pollutants easily escape from the front, rear and side of the range hood. Therefore, the general range hood often increases the suction to increase the amount of inhalation. However, this method not only increases noise, wastes energy, but also completely eliminates it. The phenomenon of leakage.
針對上述問題,常見之改善方法係如第6圖所示,在排油煙機a之左右兩側及後方分別增設擋板。然而,在實際使用時,氣流之邊界層容易在兩側板b之前緣分離而分別產生大迴流泡c,此大迴流泡c會將油煙污染物捲至兩側板b之前緣附近,並經由分子擴散與紊流擴散而洩漏,或受到環境擾動氣流之影響而被捲出至外在環境中。在排油煙機a之突緣d與側板b之交界處,由於三維效應之影響,會產生複雜的三維渦流與強烈之紊流,同樣會將污染物捲至排油煙機a之突緣d與側板b之交界處而造成洩漏。因此,單純的在排油煙機a之左右兩側分別增加側板b之方式,無法完全達到防止洩漏之效果。In view of the above problems, a common improvement method is as shown in Fig. 6, in which the baffles are respectively added to the left and right sides and the rear of the range hood a. However, in actual use, the boundary layer of the gas stream is easily separated at the leading edge of the two side plates b to generate a large return bubble c, which will roll the soot pollutants near the front edge of the two side plates b and diffuse through the molecules. It leaks out with turbulent flow, or is exposed to the external environment due to the influence of environmental disturbances. At the junction of the flange d of the range hood a and the side panel b, due to the three-dimensional effect, complex three-dimensional eddy currents and strong turbulence will be generated, and the contaminants will be rolled to the flange d of the range hood a and Leakage at the junction of the side panels b. Therefore, simply adding the side plates b to the left and right sides of the range hood a can not completely achieve the effect of preventing leakage.

When implemented, the first and second guiding portions (31) The horizontal sections of 41) may also be curved to create a guiding airflow.
左頂板32及右頂板42分別為一個倒三角形板,左頂板32及右頂板42相互對稱於吸氣罩2之底面兩側,左頂板32設於第一導引部31與抽氣口21之間,右頂板42設於第二導引部41與抽氣口21之間,具體而言,左頂板32之頂邊321向上鄰近吸氣罩2之底面左側,左頂板32之左側邊322向左鄰近左立板3之右側面;而右頂板42之頂邊421向上鄰近吸氣罩2之底面右側,右頂板42之右側邊422向右鄰近右立板4之左側面。左頂板32之頂邊321與左吹氣槽23平行,並位於左吹氣槽23之前端,右頂板42之頂邊421與右吹氣槽24平行,並位於右吹氣槽24之前端。The left top plate 32 and the right top plate 42 are respectively an inverted triangular plate, and the left top plate 32 and the right top plate 42 are symmetric with each other on both sides of the bottom surface of the suction hood 2, and the left top plate 32 is disposed between the first guiding portion 31 and the suction port 21. The right top plate 42 is disposed between the second guiding portion 41 and the air suction port 21. Specifically, the top edge 321 of the left top plate 32 is adjacent to the left side of the bottom surface of the suction hood 2, and the left side 322 of the left top plate 32 is adjacent to the left side. The right side surface of the left vertical plate 3 is adjacent to the right side of the bottom surface of the suction hood 2, and the right side 422 of the right top plate 42 is adjacent to the left side of the right vertical plate 4 to the right. The top edge 321 of the left top plate 32 is parallel to the left blowing groove 23 and is located at the front end of the left blowing groove 23. The top edge 421 of the right top plate 42 is parallel to the right blowing groove 24 and is located at the front end of the right blowing groove 24.
當左頂板32以遠離左立板3之方向向右延伸,而右頂板42以遠離右立板4之方向向左延伸時,左頂板32向右側方向延伸的一端不超過抽氣口21之左側邊緣,右頂板42向左側方向延伸的一端不超過抽氣口21之右側邊緣。實施時,左頂板32及右頂板42亦可為弧形、矩形或其他形狀但同樣具 有導流功能之板體。When the left top plate 32 extends to the right in a direction away from the left vertical plate 3, and the right top plate 42 extends leftward in a direction away from the right vertical plate 4, the end of the left top plate 32 extending in the right direction does not exceed the left edge of the suction port 21. The one end of the right top plate 42 extending in the left direction does not exceed the right edge of the suction port 21. When implemented, the left top panel 32 and the right top panel 42 may also be curved, rectangular or other shapes but also have A plate body with a flow guiding function.
藉此,如第4圖所示,係為氣流分別通過左頂板32及右頂板42之狀態。其中,當氣流分別由吸氣罩2與左、右立板(3、4)之交界處進入容置空間25內時,由於左頂板32及右頂板42之導引,原來在第6圖中因三維效應所形成之迴流泡即會消失,而讓氣流分別沿著左頂板32及右頂板42流動,最後在左頂板32及右頂板42之後端邊緣離開,並分別形成一渦漩(C、C’),此渦漩(C、C’)已遠離吸氣罩2下方之前緣。Thereby, as shown in FIG. 4, the airflow passes through the state of the left top plate 32 and the right top plate 42, respectively. Wherein, when the airflow enters the accommodating space 25 from the boundary between the suction hood 2 and the left and right vertical plates (3, 4), respectively, due to the guidance of the left top plate 32 and the right top plate 42, originally in Fig. 6 The backflow bubbles formed by the three-dimensional effect disappear, and the airflow flows along the left top plate 32 and the right top plate 42, respectively, and finally exits at the rear end edges of the left top plate 32 and the right top plate 42, and respectively form a vortex (C, C'), this vortex (C, C') is far from the front edge below the suction hood 2.
由於左、右吹氣槽(23、24)分別位於左、右頂板(32、42)之後端,因此,由左頂板32及右頂板42之後端邊緣離開並分別形成之渦漩(C、C’)即會被左、右吹氣槽(23、24)向下吹出的空氣導引,使進入抽氣口21內,以避免油煙污染物經由吸氣罩2與左、右立板(3、4)之交界處向外洩漏。另由於第一導引部31及第二導引部41之導引,則可讓左、右吹氣槽(23、24)所向下吹出的空氣能更有效的達到導引的效果。Since the left and right blowing grooves (23, 24) are respectively located at the rear ends of the left and right top plates (32, 42), the vortex (C, C) formed by the left end plate 32 and the right top plate 42 at the rear end edges respectively. ') will be guided by the air blown downward by the left and right blowing slots (23, 24), so as to enter the suction port 21 to avoid soot pollutants through the suction hood 2 and the left and right vertical plates (3, 4) The junction is leaking outward. Further, due to the guidance of the first guiding portion 31 and the second guiding portion 41, the air blown downward by the left and right blowing grooves (23, 24) can more effectively achieve the guiding effect.
請參閱第5圖所示,其為本創作排氣裝置1之第二實施例,其與第一實施例不同之處在於:由該左立板3之前端向左彎折延伸一長方形板狀之第一立板33,由右立板4之前端向右彎折延伸一長方形板狀之第二立板43,藉以更順暢的導引氣流進入吸氣罩2下方之容置空間25中。Referring to FIG. 5, it is a second embodiment of the venting device 1 which is different from the first embodiment in that a rectangular plate is bent from the front end of the left vertical plate 3 to the left. The first vertical plate 33 is bent from the front end of the right vertical plate 4 to the right to extend a rectangular plate-shaped second vertical plate 43 so as to smoothly guide the airflow into the accommodating space 25 below the suction hood 2.
因此,本創作具有以下之優點:Therefore, this creation has the following advantages:
1、本創作係於左、右立板之前端分別設置第一、第二導引部,並分別在吸氣罩之底面兩側設置左、右頂板,因此,能有效消除空氣由排氣裝置之突緣與側板之交界處所產生之三維渦流與強烈紊流,以防止污染物由吸氣罩前端之左、右兩側邊角向外洩漏。1. The creation department sets the first and second guiding portions respectively at the front ends of the left and right vertical plates, and respectively sets the left and right top plates on both sides of the bottom surface of the suction hood, thereby effectively eliminating the air by the exhaust device. The three-dimensional eddy current and strong turbulence generated at the junction of the flange and the side plate prevent the pollutant from leaking outward from the left and right sides of the front end of the suction hood.
2、本創作係於左、右立板之前端分別設置第一、第二導引部,在吸氣罩之底面兩側設置左、右頂板,並在吸氣罩之底面設有左、右吹氣槽,因此,能產生遠離排氣裝置前端開口之渦漩,並導引進入抽氣口內,從而有效防止油煙污染物由原進入路徑向外洩漏。2. The creation system is provided with first and second guiding portions respectively at the front ends of the left and right vertical plates, left and right top plates on both sides of the bottom surface of the suction hood, and left and right sides on the bottom surface of the suction hood The blowing groove, therefore, can generate a vortex away from the opening end of the exhaust device and guide into the suction port, thereby effectively preventing the soot pollutant from leaking outward from the original entry path.
綜上所述,依上文所揭示之內容,本創作確可達到預期之目的,提供一種能有效降低油煙污染物散逸,尤其是能防止污染物由吸氣罩前端之左、右兩側邊角向外洩漏之排氣裝置,極具產業上利用之價值,爰依法提出新型專利申請。In summary, according to the above disclosure, the creation can achieve the intended purpose, and provide an effective way to reduce the dissipation of soot pollutants, especially to prevent the pollutants from being left and right sides of the front end of the suction hood. The exhaust device that leaks out of the corner is of great value for industrial use, and proposes a new type of patent application according to law.
