Description
本發明係與油煙或有害氣體之排放設備有關,更詳而言之是指一種具氣幕隔離之換氣系統與換氣方法者。The present invention relates to a fume or a harmful gas discharge device, and more particularly to a gas ventilating system and a gas exchange method.
按,習知排油煙機係用以將瓦斯爐等設備產生之油煙排出室外,其相關之專利甚多,乃甚為成熟之技術領域,此處不一一贅述。According to the conventional exhaust hood, the soot produced by equipment such as gas stoves is discharged outside, and there are many related patents, which are very mature technical fields, and will not be repeated here.
由於排油煙機主要係用以排除油煙、避免油煙散逸於廚房、室內,因此,排煙效率之優劣顯得甚為重要。傳統增進排油煙機排煙效率之方式,多係提升排油煙機內抽氣馬達之運轉速度、功率,以增強吸引周圍油煙之吸力。Since the range hood is mainly used to remove the fumes and avoid the fumes from escaping in the kitchen and indoors, the merits of the exhaust efficiency are important. Traditionally, the way to improve the exhaust efficiency of the range hood is to increase the operating speed and power of the exhaust motor in the range hood to enhance the suction of the surrounding soot.
前揭提升抽氣馬達運轉速度、功率之方式雖有明顯增進排油煙機排煙效率之效果,不過,抽氣馬達之運轉速度、功率並無法無止境地提升,當瓦斯爐產生之油煙甚多時,難免仍會有部份油煙散逸出去,更會造成能源浪費與噪音提升之問題。Although the method of improving the running speed and power of the pumping motor has obvious effect of improving the exhaust efficiency of the exhaust hood, the operating speed and power of the pumping motor cannot be improved indefinitely. When the gas stove produces a lot of fumes, At the same time, it is inevitable that some of the fumes will be dissipated, which will cause energy waste and noise increase.
為此,有相關業者設計出排油煙機之隔煙設計,用以防止油煙散逸出排油煙機之可吸收範圍,如擋板式或噴氣式等。擋板式主要係延伸擋板於排油煙機周圍,以阻隔油煙散逸至外界,如中華民國新型第M329748號「排油煙機之擋煙板裝置」等專利所示,此等設計易影響烹飪動作之順暢或頭部不甚碰撞擋板,顯有不便。而噴氣式排油煙機係於瓦斯爐周圍設置一噴氣裝置,如第M356084號「汙染物排放裝置及使用該裝置之斜向單氣簾式排油煙機」等專利所示,用以利用噴出之氣體混合、帶動油煙被排油煙機吸收而排出,此等設計雖亦有避免油煙散逸之效果,惟,由於其抽氣馬達(吸收室內空氣)所吸收之氣體流量增加(噴出氣體流量加上油煙流量),仍需增加排油煙機抽氣馬達之運轉速度或功率始可有效排除油煙,顯然仍有改善之處。To this end, relevant manufacturers have designed the smoke-free design of the range hood to prevent the soot from escaping the range of absorption of the range hood, such as baffle or jet. The baffle type mainly extends the baffle around the exhaust hood to block the fumes from dissipating to the outside world. For example, the patent of the Republic of China No. M329748 "the hood of the hood" is easy to influence the cooking action. It is inconvenient if it is smooth or the head does not collide with the baffle. The jet-type range hood is provided with a jet device around the gas stove, as shown in patent No. M356084 "Contaminant discharge device and oblique single-air curtain type hood using the device", etc., for utilizing the gas ejected. The mixing and driving of the soot is absorbed and discharged by the range hood. Although these designs also have the effect of avoiding the escape of the soot, the flow rate of the gas absorbed by the pumping motor (absorbing the indoor air) is increased (the flow rate of the injected gas plus the flow of the soot) ), it is still necessary to increase the operating speed or power of the exhaust fan exhaust motor to effectively eliminate the soot, and there is obviously still improvement.
本發明之主要目的即在提供一種具氣幕隔離之換氣系統與換氣方法,其可於產生油煙或有害氣體之設備外圍形成氣幕,用以阻隔設備周圍之空氣混入油煙或有害氣體,俾不需增加排油煙機之抽氣馬達運轉速度或功率,即可有效排除油煙或有害氣體,且,氣幕之空氣係由室外引入,可產生室內換氣效果、提升室內空氣之品質者。The main object of the present invention is to provide a gas exchange system with a gas curtain isolation and a gas exchange method, which can form a gas curtain on the periphery of a device for generating soot or harmful gas, so as to block the air around the device from being mixed with soot or harmful gas.俾You can effectively eliminate soot or harmful gases without increasing the running speed or power of the exhaust motor of the range hood. Moreover, the air of the air curtain is introduced from the outside, which can produce indoor ventilation effect and improve the quality of indoor air.

Corresponding to the periphery of the device; an air suction unit connecting the air blowing member and the outdoor, comprising an air blowing device and an exhaust device, the air blowing device is connected to the air blowing device for conveying the outdoor air to The blower is blown out to form an air curtain that isolates the device from the surrounding space, and the exhaust device generates suction to discharge soot or harmful gases outside.
此外,本發明更提供一種換氣方法,主要係導引室外空氣於產生油煙之一設備外圍形成一氣幕,用以隔離油煙或有害氣體與周圍空氣,再將油煙或有害氣體排出。In addition, the present invention further provides a method for ventilating, mainly for guiding outdoor air to form a gas curtain on the periphery of a device for generating soot, for isolating oil smoke or harmful gas and surrounding air, and then discharging soot or harmful gas.
以下,茲舉本發明數較佳實施例,並配合圖式做進一步之詳細說明如後:首先,請參閱第一圖至第三圖所示,本發明一較佳實施例之具氣幕隔離之換氣系統10,係可設置於一產生油煙或有害氣體之設備1(本實施例係瓦斯爐)上方,用以可將油煙排出室外,包含有一吹氣件12與一吸排氣單元14。In the following, a preferred embodiment of the present invention will be described in detail with reference to the drawings as follows: First, please refer to the first to third figures, which have a gas curtain isolation according to a preferred embodiment of the present invention. The ventilation system 10 can be disposed above a device 1 (the gas furnace of the embodiment) for generating soot or harmful gas, so as to discharge the soot out of the room, and includes a blowing member 12 and an air suction unit 14 .
該吹氣件12,設置於該設備1上方(本實施例係設置於排油煙機2底側),包含一環型之殼體22,該殼體22底側設有一出氣口24,該出氣口24係對應設備1之外圍。The air blowing member 12 is disposed above the device 1 (this embodiment is disposed on the bottom side of the range hood 2), and includes a ring-shaped housing 22, and the bottom side of the housing 22 is provided with an air outlet 24, the air outlet The 24 series corresponds to the periphery of the device 1.
該吸排氣單元14,包含一殼體26,該殼體26內部設有分隔之二空間28、30,一吹氣裝置32與一排氣裝置34,係馬達,分別設置於該二空間28、30內,該空間28係連通吹氣件12與室外,用以該吹氣裝置32運轉時可將室外空氣輸送至吹氣件12,該空間30係連通排油煙機2之排風管路與室外,用以該排氣裝置34運轉時可將油煙排出室外。又,該二空間28、30內更分別設置有一濾網36、38。The air intake and exhaust unit 14 includes a casing 26. The casing 26 is provided with a partitioning space 28, 30, a blowing device 32 and an exhausting device 34, and a motor, which are respectively disposed in the two spaces 28 And 30, the space 28 is connected to the air blowing member 12 and the outdoor, and the outdoor air is sent to the air blowing member 12 when the air blowing device 32 is in operation, and the space 30 is connected to the air exhausting pipe of the range hood 2 With the outdoor, the soot can be discharged to the outside when the exhaust device 34 is operated. Moreover, a filter screen 36, 38 is further disposed in the two spaces 28, 30, respectively.
藉此,該吹氣裝置32與排氣裝置34可電連接排油煙機2之電控單元,俾當該排油煙機2運作時吹氣裝置32與排氣裝置34亦可作動。Thereby, the air blowing device 32 and the exhaust device 34 can be electrically connected to the electronic control unit of the range hood 2, and the air blowing device 32 and the exhaust device 34 can also be activated when the range hood 2 is in operation.
本發明該具氣幕隔離之換氣系統10之作動方式及特色、功效如下:如第四圖及第五圖所示,該吹氣裝置32運轉時,可吸引室外空氣自該吹氣件12之出氣口24朝下噴出,而形成包圍該設備1(瓦斯爐)之一氣幕40,該氣幕40可隔離設備1所產生之油煙與周圍空氣。The operation mode, characteristics and functions of the air curtain isolation ventilation system 10 of the present invention are as follows: as shown in the fourth and fifth figures, when the air blowing device 32 is in operation, the outdoor air can be attracted from the air blowing member 12 The air outlet 24 is sprayed downward to form a gas curtain 40 surrounding the apparatus 1 (gas furnace), which can isolate the soot and ambient air generated by the apparatus 1.
如此一來,該設備1周圍之空氣不會於排油煙機2排煙之過程中混入油煙,因此,該排油煙機2不需使用高功率之抽氣馬達,即可輕易地將該設備1所產生之油煙排出室外。In this way, the air around the device 1 does not mix the fumes in the process of exhausting the hood 2, so the hood 2 can easily be used without using a high-power pumping motor. The generated soot is discharged outside.
換言之,本發明該具氣幕隔離之換氣系統10不需增加該排油煙機2之抽氣馬達運轉之速度或功率,即可有效達成排除油煙之效果,有別於習知利用提昇抽氣馬達功率以增加排氣效率之排油煙機,及於瓦斯爐側增設噴氣系統以牽引油煙進入排油煙機之設計。再者,藉由該吸排氣單元14導入室外空氣之設計,更可產生室內換氣效果、增進室內空氣之品質。In other words, the ventilation system 10 with the air curtain isolation of the present invention can effectively achieve the effect of eliminating the soot without increasing the speed or power of the operation of the exhaust motor of the range hood 2, which is different from the conventional use of lifting and pumping. Motor power to increase the exhaust efficiency of the range hood, and add a jet system on the gas stove side to pull the soot into the range hood design. Furthermore, by introducing the design of the outdoor air by the air intake and exhaust unit 14, it is possible to generate an indoor air exchange effect and improve the quality of the indoor air.
如第六圖所示,係本發明另一較佳實施例之具氣幕隔離之換氣系統50,其構成大體上與該具氣幕隔離之換氣系統10相同,不同處在於更包含有一控制單元52,係包含有一感測裝置54,設置於對應油煙(如瓦斯爐一側)或有害氣體產生設備之位置,用以可感測設備產生之油煙(或有害氣體)流量Qc ,一控制部56,係運算處理器等電子元件,電連接該感測裝置54與吹氣裝置58、排氣裝置60,用以可藉由該感測裝置54傳輸之流量Qc 運算出吹氣裝置58應產生之空氣流量QE 而驅動吹氣裝置58運轉。該排氣裝置60之運轉速度係維持固定,而排油煙機排出氣體之總流量為QS 。As shown in the sixth embodiment, the ventilation system 50 with air curtain isolation according to another preferred embodiment of the present invention is substantially the same as the ventilation system 10 having the air curtain isolation, and the difference is that there is a The control unit 52 includes a sensing device 54 disposed at a position corresponding to the soot (such as the gas furnace side) or the harmful gas generating device for sensing the flow rate of the soot (or harmful gas) generated by the device Q c , The control unit 56 is an electronic component such as an arithmetic processor, and is electrically connected to the sensing device 54 and the air blowing device 58 and the exhaust device 60 for calculating the air blowing device by the flow rate Q c transmitted by the sensing device 54. The air flow rate Q E to be generated 58 drives the air blowing device 58 to operate. The operating speed of the exhaust unit 60 is maintained constant, and the total flow rate of the exhaust gas from the range hood is Q S .
上述各該流量Qc 、QE 與QS 之關係式為:The relationship between each of the above flows Q c , Q E and Q S is:
QS =Qc +QE Q S =Q c +Q E
故,空氣流量QE 與油煙流量Qc 係呈反比關係,其原理在於:當油煙流量Qc 較高時,油煙較易上升而受到排油煙機吸收而排放,此時,即不需較高之空氣流量QE 來形成氣幕。反之,當油煙流量Qc 較低時,油煙不易上升受排油煙機吸收、排放,此時,即需較高比例之空氣流量QE 來形成氣幕,以避免設備周圍之空氣混入油煙。Therefore, the air flow rate Q E is inversely proportional to the soot flow rate Q c . The principle is that when the soot flow rate Q c is high, the soot is more likely to rise and is absorbed by the exhaust hood and is discharged. The air flow Q E forms a gas curtain. Conversely, when the soot flow rate Q c is low, the soot is not easy to rise and is absorbed and discharged by the range hood. At this time, a higher proportion of the air flow rate Q E is required to form the air curtain to prevent the air around the equipment from being mixed into the soot.
藉此,該控制單元52可依據前述流量關係式控制吹氣裝置58運轉之速度:在總流量QS 滿足於將Qc 徹底吸除之狀況下,當設備產生之油煙流量Qc 較高時,該控制單元52即可使吹氣裝置58之運轉速度較低、產生較低比例之空氣流量QE 。反之,當設備產生之油煙流量Qc 較低時,該控制單元52係使吹氣裝置58之運轉速度產生較高比例之空氣流量QE ,較高比例之QE 主要目的在於確保Qc 之徹底吸除,因此,其實際流量仍較Qc 流量較高時為低。如此一來,更可有效而精確地排除油煙,達到節能減噪之目標。Thereby, the control unit 52 can control the speed of the operation of the air blowing device 58 according to the foregoing flow relationship: when the total flow rate Q S is satisfied to completely remove the Q c , when the oil smoke flow rate Q c generated by the device is high The control unit 52 can make the operation speed of the air blowing device 58 lower, and generate a lower proportion of the air flow rate Q E . Conversely, when the soot flow rate Q c generated by the device is low, the control unit 52 causes the operating speed of the air blowing device 58 to generate a higher proportion of the air flow rate Q E , and the higher proportion of Q E is mainly for ensuring Q c It is completely sucked out, so its actual flow is still lower than when the Q c flow is high. In this way, it is more effective and accurate to eliminate the soot, achieving the goal of energy saving and noise reduction.
此外,本發明該吹氣件之出氣口亦可增設受控制單元控制之一風門(圖中未示),用以可控制該出氣口噴出空氣之流量與流速。In addition, the air outlet of the air blowing member of the present invention may also be provided with a damper (not shown) controlled by the control unit for controlling the flow rate and flow rate of the air discharged from the air outlet.
由上,本發明更提供一換氣方法,係利用前述吸排氣單元與吹氣件之配合,使該吹氣件吹出導入之室外空氣而於產生油煙或有害氣體之一設備外圍形成一氣幕,用以隔離油煙與周圍空氣,再將油煙或有害氣體排出並產生換氣效果。再者,更可利用前述控制單元依據氣幕之空氣流量與油煙或有害氣體流量呈反比之關係,有效而精確地排除油煙或有害氣體。In the above, the present invention further provides a ventilation method, which utilizes the cooperation of the air suction unit and the air blowing member to blow the air blower out of the introduced outdoor air to form a gas curtain on the periphery of the device for generating soot or harmful gas. It is used to isolate the soot from the surrounding air, and then discharge the soot or harmful gas to produce a ventilation effect. Furthermore, the aforementioned control unit can effectively and accurately eliminate the soot or harmful gas according to the inverse relationship between the air flow rate of the air curtain and the flow rate of the oil smoke or the harmful gas.
值得一提的是,本發明亦可增設油氣分離或有害氣體處理裝置,用以可將油、氣分離或防止有害氣體排至室外而汙染室外空氣。It is worth mentioning that the present invention can also add an oil and gas separation or harmful gas treatment device for separating oil or gas or preventing harmful gases from being discharged to the outside to pollute the outdoor air.
综上所述,本發明所提供之具氣幕隔離之換氣系統與換氣方法,其於產生油煙或有害氣體之一設備外圍形成氣幕,用以阻隔設備周圍之空氣混入油煙或有害氣體,俾不需增加排油煙機之抽氣馬達運轉速度或功率,即可有效排除油煙或有害氣體,且,其係利用室外空氣形成氣幕,可產生室內換氣效果、有益於室內空氣之品質;緣是,本發明確實符合發明專利之要件,爰依法提出申請。In summary, the present invention provides a gas screen isolation ventilation system and a gas exchange method, which forms a gas curtain on the periphery of a device for generating soot or harmful gas, and is used for blocking air mixed with soot or harmful gas around the device.俾You can effectively eliminate soot or harmful gases without increasing the running speed or power of the exhaust motor of the range hood. Moreover, it uses the outdoor air to form a gas curtain, which can generate indoor ventilation effect and benefit the quality of indoor air. The reason is that the invention does meet the requirements of the invention patent and submits an application in accordance with the law.
