Description of the invention: [Technical field to which the invention pertains] The present invention relates to a discharge device for soot or harmful gases, and more particularly to a ventilation system with a gas curtain isolation and a ventilation method. Technology] According to the conventional exhaust hood, it is used to discharge the fumes from equipment such as gas stoves. Many related patents are in the mature technical field 'here no.' Since the range hood is mainly used to remove soot and to avoid the fumes from dissipating in the kitchen to beta, the merits of the exhaust efficiency are important. Traditionally, the operating speed and power of the exhaust motor in the range hood of the exhaust hood are improved to:;; = the suction of the oil fume. 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 time, it is inevitable that some of the fumes will still be dissipated, which will cause energy waste and noise increase. To this end, the relevant manufacturers have designed the smoke-free design of the range hood to prevent the fumes from escaping the range hood ^ ^ < J absorption of the circumference, such as baffle or jet. The baffle-type main I technology is to extend the baffle around the exhaust hood to block the fumes from dissipating to the outside world, such as the patent of the Republic of China New Type 201239279 M329748 "The hood of the hood". The design is easy to affect the smoothness of each movement or the head does not collide with the board. It is inconvenient. 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 #玄装置", etc. The gas is mixed and the soot is absorbed and discharged by the exhaust hood. Although these designs also have the effect of avoiding the escape of the soot, the gas flow absorbed by the pumping horse (absorbing indoor air) is added (the gas flow rate is ejected). In addition to the soot flow rate, it is still necessary to increase the operating speed or power of the exhaust fan exhaust motor to effectively eliminate the fumes, but there are still improvements. SUMMARY OF THE INVENTION The main purpose of the present invention is to provide a system with air curtain isolation: a system and a gas exchange method, which can be used to generate soot or harmful gases: a gas curtain is formed to block the air around the device. Mixing in the soot: The gas '俾 does not need to increase the speed or power of the exhaust motor of the range hood, so that the smoke can be effectively eliminated or the air system with # is externally induced, a — the inside air is produced internally. Ventilation effect, lifting chamber gas 2 = the purpose of the description 'The present invention provides - the tool = gas Zhao discharge outdoor' contains a blowing member, including a ring type 糸 corresponding to the periphery of the device; a suction and exhaust unit, connected to the 4 201239279, gas and outdoor 'includes a blowing device and a venting device, the blowing device is connected to the blowing member for blowing the outdoor air to the blowing member to form the isolation device and the surrounding Space-air curtain, the exhaust device generates suction to discharge soot or harmful gases outside. In addition, the present invention further provides a method of ventilating, mainly for guiding outdoor air to form a gas curtain on the periphery of a device for generating soot, for isolating the soot or harmful gas from the surrounding air, and then discharging the soot or the treasure. σ ” ” 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施 实施A ventilation system with a gas curtain isolation according to a preferred embodiment can be disposed in a device for generating soot or harmful gas. 1 (This embodiment is a tile: the furnace is used to discharge the soot out of the room) Including and venting member m suction and exhaust unit 14. ^ The blowing member 12 is disposed on the apparatus 1 (the embodiment is disposed on the bottom side of the range hood 2), and includes a ring type housing 1 The bottom side of the housing 22 is provided with an air outlet 24, which is corresponding to the periphery of the device 1. The air intake unit Η' comprises a housing 26, and the housing 仏 is provided with a partition space 28 therein. 30', a blowing device 32 and an exhaust device 34, are motors, respectively disposed in the two spaces μ,%, 201239279, the space 28 is connected to the air blowing device 丨2 and the outdoor, for the air blowing device When the operation is 32, the outdoor air can be sent to the air blowing member 12, and the space is connected to the exhaust pipe of the range hood 2 And the outdoor, when the exhaust device 34 is operated, the soot can be discharged outside. Further, the two spaces 28 and 30 are respectively provided with a net 3 63 8 . Thereby, the air blow device 32 and the exhaust gas The device 34 can be electrically connected to the electric 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. The air curtain isolating ventilation system of the present invention The operation mode, the characteristics, and the functions 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 sucked out from the air outlet 24 of the air blowing member 24, and the surrounding air is formed. The air curtain 4 of the equipment 1 (gas furnace) can isolate the soot and the surrounding air generated by the equipment 。. Therefore, the air around the equipment 1 is not in the process of exhausting the hood 2 The soot is mixed in. Therefore, the range hood 2 can easily discharge the soot generated on the device from the outside without using a pumping motor of a power of 冋. In other words, the gas venting system 1 of the present invention is provided. 〇You don’t need to add the pumping motor of the Hai Range hood 2 Degree or power, that is, J effectively achieves the effect of eliminating the soot, which is different from the conventional range hood that uses the power of the pumping motor to increase the exhaust efficiency, and adds a jet system on the gas stove side to pull the soot into the range hood. Design. In addition, the design of the outdoor air is introduced by the air intake and exhaust unit, and the indoor ventilation effect is improved and the quality of the indoor air is improved. As shown in the sixth figure, it is another preferred embodiment of the present invention. The embodiment of the air curtain isolating ventilation system 50' is substantially identical to the air curtain isolated ventilation system 1'. The difference is that the control unit 52' includes a sensing device 54. In the position corresponding to the soot (such as gas furnace-side) or the harmful gas generating device, the soot (or harmful gas) flow rate Qe generated by the device can be sensed, a control unit 56, an electronic component such as an arithmetic processor, and an electrical connection The sensing device Μ and the blowing device 58 and the exhaust device 60 are configured to calculate the air flow rate Qe that the air blowing device 58 should generate by the flow rate Qc transmitted by the sensing device 54 to drive the air blowing device. 58 operation. The operating speed of the exhaust unit 6〇 is maintained constant, and the total flow rate of the exhaust gas from the range hood is . The relationship between each of the above flows Qc, QE and qs is:
Qs= Qc+ qe 故，空氣流量Qe與油煙流量Qe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 叉到排油煙機吸收而排放，此時，即不需較高之空氣 流I QE來形成氣幕。反之，當油煙流量Qe較低時， 油煙不易上升受排油煙機吸收、排放’此時，即需較 鬲比例之二氣流置Q E來形成氣幕，以避免設備周圍之 空氣混入油煙。 藉此’該控制單元52可依據前述流量關係式控制 201239279 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Qe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Qe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。 > 此外，本發明該吹氣件之出氣口亦可增設受控制 :元㈣之一風門（圖中未示)，用以可控制該出氣口 喷出空氣之流量與流速。 由上，本發明更提供一換氣方法， 排氣單元與吹氣件之配合 t酉己合》使該口欠斋杜#Qs= Qc+ qe Therefore, the air flow rate Qe is inversely proportional to the soot flow rate Qe. The principle is: when the soot flow rate Qc is high, the soot is easy to rise and the fork is discharged to the range hood and is discharged. The higher air flow I QE forms the air curtain. Conversely, when the soot flow rate Qe is low, the soot is not easy to rise and is absorbed and discharged by the range hood. At this time, it is necessary to set the air curtain by the airflow of the second ratio to avoid the air around the equipment being mixed into the soot. Therefore, the control unit 52 can control the running speed of the air blower 58 according to the foregoing flow relationship: when the total flow rate qs is satisfied to completely remove the qc, when the soot flow rate Qc generated by the device is high, The control unit 52 can cause the blowing device 58 to operate at a lower speed and produce a lower proportion of the air flow rate Qe. On the contrary, when the soot flow rate Qe 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 Qe, and the higher proportion of the QE is mainly to ensure the complete suction of the Qc. Therefore, the actual traffic is still lower than when the Qe traffic is high. In this way, the soot can be more effectively/effectively and accurately eliminated, achieving the goal of energy saving and noise reduction. > In addition, the air outlet of the air blowing member of the present invention may be additionally controlled: one of the air (four) dampers (not shown) for controlling the flow rate and flow rate of the air discharged from the air outlet. From the above, the present invention further provides a ventilation method, the cooperation between the exhaust unit and the blower member, t酉己合", the mouth is owed to the fast Du #
