請參照第1圖，係繪示依照本發明一實施方式之實施例1的文氏管式自然通風裝置100的立體示意圖。由第1圖可知，文氏管式自然通風裝置100包含第一管體110、喉 部130、第二管體120以及抽吸連接管體140，其中第一管體110與第二管體120由喉部130連接並連通，且喉部130更與抽吸連接管體140連接且連通。第一管體110、喉部130以及第二管體120的連接組合可構成文氏管式的結構，配合抽吸連接管體140的結構與室內連通，即可有效針對室內進行抽風。Referring to FIG. 1 , a perspective view of a venturi-type natural ventilation device 100 according to Embodiment 1 of an embodiment of the present invention is shown. As can be seen from Figure 1, the Venturi tubular natural ventilation device 100 includes a first tubular body 110 and a throat. The portion 130, the second tube body 120, and the suction connection tube body 140, wherein the first tube body 110 and the second tube body 120 are connected and connected by the throat portion 130, and the throat portion 130 is further connected to the suction connection tube body 140. Connected. The connection combination of the first pipe body 110, the throat portion 130 and the second pipe body 120 can constitute a venturi-type structure, and the structure of the suction connection pipe body 140 can be communicated with the indoor environment, so that the indoor air can be effectively extracted.
配合參照第2圖及第3圖，其中第2圖繪示依照第 1圖實施例1之文氏管式自然通風裝置100的側視圖，第3圖繪示依照第1圖實施例1之文氏管式自然通風裝置100的俯視圖。詳細來說，第一管體110具有相對應的第一管壁111及第二管壁112，以及相對應的第三管壁113及第四管壁114。第一管壁111與第二管壁112相對應平行設置。 第三管壁113與第四管壁114間則設有一夾角，使第三管壁113與第四管壁114分別連接於喉部130一端的間距d1小於另一端的間距d2，其中d1為200mm，d2為500mm；也就是說，第一管體110透過第三管壁113及第四管壁114的配置，呈現由內朝外漸擴的管型。換句話說，第一管體110之一端為第一開口(d2處)，另一端為第二開口(d1處)，其中第一開口之開口面積大於第二開口之開口面積。藉此，有助於捕捉較多的風量，並進而提升喉部130的風速及降低該處的壓力，此舉將有效吸引室內氣流經過抽吸連接管體140進入本文氏管式自然通風裝置100，以達提升抽風量的目的。With reference to Figure 2 and Figure 3, Figure 2 depicts 1 is a side view of the venturi natural ventilation device 100 of the first embodiment, and FIG. 3 is a plan view of the venturi natural ventilation device 100 according to the first embodiment of the first embodiment. In detail, the first pipe body 110 has a corresponding first pipe wall 111 and a second pipe wall 112, and corresponding third pipe wall 113 and fourth pipe wall 114. The first tube wall 111 is disposed in parallel with the second tube wall 112. The third pipe wall 113 and the fourth pipe wall 114 are disposed at an angle such that the distance d1 between the third pipe wall 113 and the fourth pipe wall 114 connected to one end of the throat 130 is smaller than the distance d2 of the other end, wherein d1 is 200 mm. The d2 is 500 mm; that is, the first pipe body 110 is configured to pass through the third pipe wall 113 and the fourth pipe wall 114, and exhibits a pipe shape which is diverging from the inside to the outside. In other words, one end of the first pipe body 110 is a first opening (at d2), and the other end is a second opening (at d1), wherein an opening area of the first opening is larger than an opening area of the second opening. Thereby, it is helpful to capture more air volume, and thereby increase the wind speed of the throat 130 and reduce the pressure there, which will effectively attract the indoor airflow through the suction connection pipe body 140 into the pipe-type natural ventilation device 100. In order to achieve the purpose of increasing the amount of air.
第二管體120透過喉部130與第一管體110連通。 第二管體120具有相對應的第一管壁121及第二管壁122，以及相對應的第三管壁123以及第四管壁124。由第2圖可知，第一管壁121與第二管壁122相對平行設置，且第一管壁121與第二管壁122水平連接於喉部130。因此，當文氏管式自然通風裝置100設置室外、屋頂時，可避免雨水由沿第二管體120的管壁流入。The second tubular body 120 communicates with the first tubular body 110 through the throat 130. The second pipe body 120 has a corresponding first pipe wall 121 and a second pipe wall 122, and a corresponding third pipe wall 123 and a fourth pipe wall 124. As can be seen from FIG. 2, the first tube wall 121 and the second tube wall 122 are disposed in parallel with each other, and the first tube wall 121 and the second tube wall 122 are horizontally connected to the throat portion 130. Therefore, when the venturi-type natural ventilation device 100 is installed outdoors and on the roof, rainwater can be prevented from flowing in from the pipe wall along the second pipe body 120.
第二管體120之第三管壁123及第四管壁124分別與喉部130以一角度A連接，且角度A介於7.4度至15度間，其中第3圖實施例1中所揭示之角度A為7.41度。藉此，透過第三管壁123及第四管壁124設置於適當的角度，更有助於降低喉部130位置的壓力，以有效的吸引室內氣流進入本裝置。The third tube wall 123 and the fourth tube wall 124 of the second tube body 120 are respectively connected to the throat portion 130 at an angle A, and the angle A is between 7.4 degrees and 15 degrees, wherein the third embodiment is disclosed in the first embodiment. The angle A is 7.41 degrees. Thereby, the third tube wall 123 and the fourth tube wall 124 are disposed at an appropriate angle, which further helps to lower the pressure of the throat 130 to effectively attract the indoor airflow into the device.
再參照第4圖，係繪示依照本發明一實施方式之實施例2的文氏管式自然通風裝置100的俯視圖。由第4圖可知，文氏管式自然通風裝置100中，第二管體120之第三管壁123及第四管壁124相對應平行設置，也就是說，第三管壁123及第四管壁124分別以0度(角度A)與喉部130連接。Referring again to Fig. 4, there is shown a plan view of a venturi-type natural ventilation device 100 according to Embodiment 2 of an embodiment of the present invention. As can be seen from FIG. 4, in the venturi-type natural ventilation device 100, the third pipe wall 123 and the fourth pipe wall 124 of the second pipe body 120 are correspondingly arranged in parallel, that is, the third pipe wall 123 and the fourth pipe. The tube wall 124 is connected to the throat 130 at 0 degrees (angle A).
下列表一為本發明實施例1、實施例2以及比較例之室內抽風量的體積流率。The following Table 1 is the volume flow rate of the indoor exhaust air volume according to the first embodiment, the second embodiment, and the comparative example of the present invention.
其中，實施例1為第1圖所揭示之文氏管式自然通 風裝置100，其第二管體120之第一管壁121與第二管壁122水平連接至喉部130，且其第二管體之第三管壁123及第四管壁124分別以7.41度(角度A)與喉部130連接。實施例2為第4圖所揭示之文氏管式自然通風裝置100，其第二管體120之第一管壁121與第二管壁122水平連接至喉部130，且其第二管體之第三管壁123及第四管壁124分別以0度(角度A)與喉部130連接。另外，配合參照第5A圖及第5B圖，其係為比較例1及比較例2文氏管式自然通風裝置200的側視圖。第5A圖中，比較例1之文氏管式自然通風裝置200之第二管體220的第一管壁221及第二管壁222非相對應平行設置，且分別以θ1 為5度以及水平(即θ2 為0度)的角度與喉部130連接。第5B圖中，比較例2之文氏管式自然通風裝置200之第二管體220的第一管壁221及第二管壁222亦非相對應平行設置，而是分別以θ1 為5度以及θ2 為5度的角度與喉部130連接。The first embodiment has a venturi natural ventilation device 100 as disclosed in FIG. 1 , wherein the first tube wall 121 and the second tube wall 122 of the second tube body 120 are horizontally connected to the throat portion 130, and the second portion thereof The third tube wall 123 and the fourth tube wall 124 of the tubular body are connected to the throat 130 at 7.41 degrees (angle A), respectively. Embodiment 2 is the venturi natural ventilation device 100 disclosed in FIG. 4, wherein the first pipe wall 121 and the second pipe wall 122 of the second pipe body 120 are horizontally connected to the throat 130, and the second pipe body thereof The third tube wall 123 and the fourth tube wall 124 are connected to the throat 130 at 0 degrees (angle A), respectively. In addition, referring to FIG. 5A and FIG. 5B, it is a side view of the venturi-type natural ventilation device 200 of Comparative Example 1 and Comparative Example 2. In Fig. 5A, the first tube wall 221 and the second tube wall 222 of the second tube body 220 of the venturi-type natural ventilation device 200 of Comparative Example 1 are not disposed in parallel, and are respectively θ 1 of 5 degrees and The angle of the horizontal (i.e., θ 2 is 0 degrees) is connected to the throat 130. In Fig. 5B, the first tube wall 221 and the second tube wall 222 of the second tube body 220 of the venturi-type natural ventilation device 200 of Comparative Example 2 are not correspondingly arranged in parallel, but are respectively θ 1 of 5 The angle and the angle θ 2 of 5 degrees are connected to the throat 130.
配合上述表一可知，當第二管體120的第一管壁 121及第二管壁122相對應平行且與喉部130水平連接，除了可避免下雨時雨水自第二管體120流入室內，更有助於提升室內抽風量。再者，由實施例1及實施例2的比較可知，當第二管體120之第三管壁123及第四管壁124分別 以角度A且角度A不為零與喉部130連接，其達到的室內抽風量大於第三管壁123及第四管壁124分別以角度A為零的方式連接於喉部130的結構。As can be seen from Table 1 above, when the first pipe wall of the second pipe body 120 121 and the second pipe wall 122 are correspondingly parallel and horizontally connected to the throat 130, except that rainwater can be prevented from flowing into the room from the second pipe body 120 when it is raining, which is more helpful for increasing the amount of air exhausted in the room. Furthermore, it can be seen from the comparison between the first embodiment and the second embodiment that the third tube wall 123 and the fourth tube wall 124 of the second tube body 120 are respectively The angle A and the angle A are not zero connected to the throat 130, and the amount of indoor exhaust air that is achieved is greater than the structure in which the third pipe wall 123 and the fourth pipe wall 124 are connected to the throat 130 at an angle A of zero, respectively.
繼續參照第6圖，係繪示依照本發明一實施方式之實施例3的文氏管式自然通風裝置100的剖視圖。實施例3的文氏管式自然通風裝置100之第一管體110、第二管體120、喉部130以及抽吸連接管體140之結構及配設連接關係與第1圖實施例1相同，在此不加贅述。第6圖中，文氏管式自然通風裝置100更可包含風力發電裝置150，設置於第二管體120中。由於文氏管式自然通風裝置100透過第一管體110、第二管體120、喉部130以及抽吸連接管體140的配置已可達到空氣對流的功效，而風力發電裝置150可受原本排出的空氣驅動而轉動，達到額外發電儲能的目的。風力發電裝置150設置於第二管體120中的位置與第二管體120之開口的距離為D，其中D為0mm至150mm。詳述之，實施例3中D為150mm。藉此，除有助於提升文氏管式自然通風裝置100的室內抽風量，使其達到良好的室內通風效果外，更可同時產生電能，達到風力發電的環保效應。With continued reference to Fig. 6, a cross-sectional view of a venturi-type natural ventilation device 100 according to Embodiment 3 of an embodiment of the present invention is shown. The structure and arrangement of the first pipe body 110, the second pipe body 120, the throat portion 130, and the suction connection pipe body 140 of the venturi-type natural ventilation device 100 of the third embodiment are the same as those of the first embodiment of the first embodiment. I will not repeat them here. In FIG. 6 , the venturi natural ventilation device 100 further includes a wind power generation device 150 disposed in the second pipe body 120 . Since the Venturi tubular natural ventilation device 100 can achieve the effect of air convection through the configuration of the first pipe body 110, the second pipe body 120, the throat portion 130, and the suction connection pipe body 140, the wind power generation device 150 can be subjected to the original The discharged air is driven and rotated to achieve the purpose of additional power generation and energy storage. The distance between the position where the wind power generator 150 is disposed in the second pipe body 120 and the opening of the second pipe body 120 is D, where D is 0 mm to 150 mm. In detail, in Example 3, D is 150 mm. In this way, in addition to helping to increase the indoor air volume of the venturi-type natural ventilation device 100 to achieve a good indoor ventilation effect, it is also possible to generate electric energy at the same time to achieve the environmental protection effect of wind power generation.
再參照第7圖，係繪示依照本發明一實施方式之實施例4的文氏管式自然通風裝置100的剖視圖。實施例4的文氏管式自然通風裝置100之第一管體110、第二管體120、喉部130以及抽吸連接管體140之結構及配設連接關係與第1圖實施例1相同，在此不加贅述。第7圖中，文 氏管式自然通風裝置100更可包含風力發電裝置150，設置於第二管體120中，且與第二管體120之開口的距離為D，而D為0mm；也就是說，本實施例的風力發電裝置150設置於第二管體120之開口處。藉此，除可提升抽風性能外，尚能產生不錯的發電儲能效果。Referring again to FIG. 7, a cross-sectional view of a venturi-type natural ventilation device 100 according to Embodiment 4 of an embodiment of the present invention is shown. The structure and arrangement of the first pipe body 110, the second pipe body 120, the throat portion 130, and the suction connection pipe body 140 of the venturi-type natural ventilation device 100 of the fourth embodiment are the same as those of the first embodiment of the first embodiment. I will not repeat them here. In Figure 7, the text The tubular natural ventilation device 100 further includes a wind power generation device 150 disposed in the second pipe body 120 and having a distance D from the opening of the second pipe body 120, and D is 0 mm; that is, the embodiment The wind power generator 150 is disposed at the opening of the second pipe body 120. In this way, in addition to improving the ventilation performance, it can still produce a good power generation and storage effect.
綜上所述，風力發電裝置150的設置位置介於0mm至150mm，皆可提升抽風性能，並產生不錯的發電儲能效果。In summary, the setting position of the wind power generation device 150 is between 0 mm and 150 mm, which can improve the ventilation performance and produce a good power generation and energy storage effect.
下列表二為本發明實施例3及實施例4之室內抽風量的體積流率及風力發電裝置的輸出扭力。Table 2 below shows the volumetric flow rate of the indoor exhaust air volume and the output torque of the wind power generator according to the third and fourth embodiments of the present invention.
由上述表二可知，相較於實施例1及實施例2沒有設置風力發電裝置的文氏管式自然通風裝置100，實施例3及實施例4包含有風力發電裝置150，確實可提升室內抽風量，改善室內通風效果，且同時可產生一定的發電量。As can be seen from the above Table 2, the venturi-type natural ventilation device 100 of the wind power generation device is not provided in the first embodiment and the second embodiment, and the third embodiment and the fourth embodiment include the wind power generation device 150. The amount of air is used to improve the indoor ventilation effect, and at the same time, it can generate a certain amount of power generation.
另外，下列表三為當第3圖實施方式中文氏管式自然通風裝置100的第二管體120之第三管壁123及第四 管壁124設置的角度A分別為0度、7.5度、15度及22.5度時，配合設置於第二管體120開口處的風力發電裝置150可達成的室內抽風量。In addition, the following table 3 is the third pipe wall 123 and the fourth pipe of the second pipe body 120 of the Chinese pipe type natural ventilation device 100 in the embodiment of FIG.
