Description

氣流吐出單元以及流體設備Air flow discharge unit and fluid equipment

本發明之一實施形態，係關於氣流吐出單元以及流體設備。An embodiment of the present invention relates to an air flow discharge unit and a fluid device.

近年來，利用流體元件的機器係為人所知。所謂流體元件，係以流體(液體或氣體)作為作動體的控制元件的總稱。特別是，被稱為純流體元件的流體元件，係不具備可動部，而僅藉由流體的運動進行流體的控制。In recent years, machines using fluid elements have been known. The so-called fluid element is a general term for a control element that uses fluid (liquid or gas) as an actuating body. In particular, a fluid element called a pure fluid element does not have a movable part, but only controls the fluid by the movement of the fluid.

作為安裝於空氣淋浴裝置的純流體元件的技術，日本特開2004-275985號公報所記載的技術係為人所知。As a technology of a pure fluid element attached to an air shower device, the technology described in Japanese Patent Laid-Open No. 2004-275985 is known.

該文獻所記載之純流體元件，係具備流體流入口、從該流體流入口流入的流體所橫跨的連結導管、橫跨該連結導管的流體所流出的流體噴出噴嘴。純流體元件，係藉由於噴出噴嘴流動的流體所產生的壓力差，驅動連結導管內的流體。對應於藉由該驅動所產生之連結導管內的流體的流動，從噴出噴嘴流出的流體的流速進行變動。連結導管，係具有剖面以曲線構成且左右對稱的2條流路。該2條流路，係在流動於連結導管的流體與流動於流體流入口至流體噴出噴嘴之間的流體的匯流點匯流。The pure fluid element described in this document is provided with a fluid inflow port, a connecting duct across which fluid flowing in from the fluid inflow port, and a fluid ejection nozzle through which fluid flowing across the connecting duct flows out. The pure fluid element drives the fluid in the connecting duct by the pressure difference generated by the fluid flowing from the spray nozzle. The flow velocity of the fluid flowing out of the discharge nozzle varies according to the flow of the fluid in the connecting duct generated by this driving. The connecting duct has two flow paths whose cross sections are formed by curves and are bilaterally symmetrical. These two flow paths merge at the confluence point of the fluid flowing through the connecting duct and the fluid flowing between the fluid inlet and the fluid ejection nozzle.

[發明所欲解決的技術課題][Technical problem to be solved by the invention]

然而，日本特開2004-275985號公報所記載的技術，係有使用者難以獲得氣流的"搖動"的效果及實際感受之問題。However, the technology described in Japanese Patent Laid-Open No. 2004-275985 has a problem that it is difficult for users to obtain the effect of "shake" of the airflow and the actual feeling.

例如，以手持型的吹風機而言，使用者自己以手動將吹風機本身上下或左右搖動，藉此來自吹風機的風會上下或左右搖動。若欲藉由氣流的自激振動獲得與此相同的效果，氣流係必須上下或左右緩慢搖動。然而，以日本特開2004-275985號公報所記載的純流體元件而言，係難以實現。亦即，該文獻所記載的純流體元件，有著使用於除塵目的之意圖。因此，該純流體元件，會產生出大且強的氣流。該氣流會成為敲打般的氣流，故使用者難以獲得氣流的"搖動"的效果及實際感受。For example, in the case of a hand-held hair dryer, the user manually shakes the hair dryer itself up and down or left and right, whereby the wind from the hair dryer will shake up and down or left and right. If you want to obtain the same effect through the self-excited vibration of the airflow, the airflow system must be slowly shaken up and down or left and right. However, the pure fluid element described in Japanese Patent Laid-Open No. 2004-275985 is difficult to realize. That is, the pure fluid element described in this document has the intention of being used for dust removal purposes. Therefore, the pure fluid element generates a large and strong air flow. This airflow will become a beating-like airflow, so it is difficult for users to obtain the effect and actual feeling of "shaking" of the airflow.

有鑑於如此之課題，本發明之一實施形態之1個目的，係在於提高來自流體設備的氣流的"搖動"效果。 [用以解決課題的技術方案]In view of such a problem, one object of an embodiment of the present invention is to increase the "shake" effect of airflow from a fluid device. [Technical Solution to Solve the Problem]

As another example, the body 110 may be a fixed-type hair dryer. In addition, the body 110 may be a fluid device other than a device that sends wind to the head (for example, a dryer, an electric fan, a pet hair dryer, and a smoke generator). The body 110 may be a device for the airflow from the airflow discharge unit 120 to flow out.

Fig. 7 is a front view showing a state where the air flow discharge unit of the fluid device according to one embodiment of the present invention has been installed on the main body.

如第4圖至第6圖所示，氣流吐出單元120，係安裝於本體110的風吹出口112的前端而使用。於此例中，氣流吐出單元120，係直接安裝於本體110的風吹出口112而使用。然而不限於此，氣流吐出單元120，以在氣流吐出單元120與本體110之間中介有其他構件的狀態，安裝於本體110亦可。另外，氣流吐出單元120之對於本體110的安裝角度(繞風吹出口112的中心的相對角度)，係不限於本實施形態所說明的角度，為對於本實施形態所說明的安裝角度偏移±90°的安裝角度亦可。As shown in FIGS. 4 to 6, the air flow discharge unit 120 is used by being attached to the front end of the air outlet 112 of the main body 110. In this example, the airflow discharge unit 120 is used by being directly attached to the air outlet 112 of the main body 110. However, it is not limited to this, and the airflow discharge unit 120 may be mounted on the body 110 in a state where other components are interposed between the airflow discharge unit 120 and the body 110. In addition, the installation angle of the airflow discharge unit 120 to the body 110 (relative angle around the center of the air outlet 112) is not limited to the angle described in this embodiment, and is an offset of ±90 from the installation angle described in this embodiment. ° Installation angle is also available.

如第5圖所示，氣流吐出單元120，係形成為具有朝向送風方向的微錐狀。然而，氣流吐出單元120，形成為具有相反於送風方向的微錐狀亦可，形成為圓柱形亦可。As shown in FIG. 5, the air flow discharge unit 120 is formed to have a micro-cone shape toward the air blowing direction. However, the air flow discharge unit 120 may be formed in a micro-cone shape opposite to the air blowing direction, or may be formed in a cylindrical shape.

如第6圖所示，氣流吐出單元120的縱方向的寬度W1，係形成為比本體110的風吹出口112之縱方向的寬度W2更大，並且，氣流吐出單元120的流出口124之縱方向的寬度，係形成為比本體110的風吹出口112之縱方向的寬度W2更大。As shown in FIG. 6, the width W1 of the air outlet unit 120 in the longitudinal direction is formed to be larger than the width W2 of the air outlet 112 of the body 110 in the longitudinal direction, and the outlet 124 of the air outlet unit 120 in the longitudinal direction Is formed to be larger than the width W2 of the main body 110 in the longitudinal direction of the wind outlet 112.

如第7圖所示，氣流吐出單元120的內部係空洞，且係用以使從本體110送風而來的氣流自流出口124送風至外部的流路。As shown in FIG. 7, the inside of the air flow discharge unit 120 is a cavity, and is a flow path for blowing air flow from the main body 110 from the outlet 124 to the outside.

＜流體設備的氣流吐出單元的構成＞ [流出口的構成] 　　第8圖，係表示本發明之一實施形態之流體設備的氣流吐出單元的流出口側的構成的立體圖。第9圖，係從流出口側觀察本發明之一實施形態之流體設備的氣流吐出單元的剖面圖。<Structure of the airflow discharge unit of the fluid equipment> [Structure of the outlet] FIG. 8 is a perspective view showing the structure of the airflow discharge unit of the fluid equipment of one embodiment of the present invention on the outlet side. Fig. 9 is a cross-sectional view of the air flow discharge unit of the fluid device according to an embodiment of the present invention viewed from the outflow side.

如第8圖所示，界定流出口124的外周部123，係具有兩部位的凹部127。藉由設置兩部位的凹部127，能夠更順暢地進行後述之對於上方及下方之風向切換。As shown in FIG. 8, the outer peripheral portion 123 defining the outlet 124 has two concave portions 127. By providing the concave portions 127 at two locations, it is possible to more smoothly switch the wind directions above and below, which will be described later.

亦即，如後述般，本發明之一實施形態之流體設備的氣流吐出單元120，係藉由持續地切換沿著上部140的氣流X及沿著下部142的氣流Y，使氣流上下搖動。此時，氣流係藉由附壁效應，沿著壁前進。因此，在左右沒有凹部127，且左右亦有壁存在的情形，「氣流X或是氣流Y」的一部分係沿著取代凹部127存在之左右的壁前進。因此。氣流X或氣流Y會分散。That is, as will be described later, the airflow discharge unit 120 of the fluid device according to an embodiment of the present invention continuously switches the airflow X along the upper portion 140 and the airflow Y along the lower portion 142 to shake the airflow up and down. At this time, the airflow advances along the wall by the effect of the attached wall. Therefore, when there are no recesses 127 on the left and right, and there are walls on either side, a part of the "airflow X or airflow Y" advances along the left and right walls instead of the recesses 127. therefore. Airflow X or airflow Y will be dispersed.

因此，於本發明之一實施形態之流體設備的氣流吐出單元120的流出口124，形成有外周部123。該外周部123，係於上下方向中央部具備有一對梯形的凹部127。一對梯形的凹部127，係在對於欲使氣流搖動的方向(於此例中係上下)為垂直的方向(於此例中係左右)排列，並分別朝向流入口122側凹陷。藉此，能夠抑制氣流分散至與欲使氣流搖動的方向不同的方向，並且能夠獲得更強的氣流的搖動效果。又，並非必須將凹部127構成為梯形。凹部127，係構成為三角形亦可，構成為U字形亦可。另外，在欲使氣流左右搖動的情形，以使一對凹部127於外周部123的左右方向中央部在上下方向排列的方式，調整氣流吐出單元120之對於本體110的安裝角度即可。Therefore, the outer peripheral portion 123 is formed in the outlet 124 of the airflow discharge unit 120 of the fluid device according to an embodiment of the present invention. The outer peripheral portion 123 is provided with a pair of trapezoidal recesses 127 at the center in the vertical direction. A pair of trapezoidal recesses 127 are arranged in a direction perpendicular to the direction in which the airflow is to be shaken (in this example, up and down) (in this example, left and right), and are recessed toward the inlet 122 side. With this, it is possible to suppress the airflow from being dispersed in a direction different from the direction in which the airflow is to be shaken, and it is possible to obtain a stronger airflow shaking effect. In addition, it is not necessary to form the concave portion 127 in a trapezoidal shape. The concave portion 127 may be configured as a triangle, or may be configured as a U-shape. In addition, when the air flow is to be shaken left and right, the mounting angle of the air flow discharge unit 120 to the main body 110 may be adjusted so that the pair of recesses 127 are arranged in the vertical direction at the center of the outer peripheral portion 123 in the left-right direction.

如第9圖所示，流出口124，係形成為橢圓形。以剖面觀察時之流出口124的面積A2，係比流入口122的面積A1更大。流出口124附近之氣流吐出單元120的內壁，係形成為具有朝向流出口124的逆錐狀。氣流係藉由附壁效應，沿著壁前進。因此，藉由使氣流吐出單元120為如此之形狀，能夠獲得寬廣地搖動的風。As shown in FIG. 9, the outflow port 124 is formed into an ellipse. The area A2 of the outflow port 124 when viewed in section is larger than the area A1 of the inflow port 122. The inner wall of the air flow discharge unit 120 near the outflow port 124 is formed to have a reverse tapered shape toward the outflow port 124. The airflow advances along the wall by the wall effect. Therefore, by making the airflow discharge unit 120 into such a shape, it is possible to obtain a wind that shakes widely.

[流出口的構成] 　　第10圖，係表示本發明之一實施形態之流體設備的氣流吐出單元的流入口的分解立體圖。[Structure of Outflow Port] FIG. 10 is an exploded perspective view showing an inflow port of an air flow discharge unit of a fluid device according to an embodiment of the present invention.

如第10圖所示，氣流吐出單元120的突出部126，係使來自本體110的氣流流入的流入口122。於此例中，突出部126係藉由螺固，與流出口124側的構件組合。使氣流吐出單元120的突出部126嵌合於本體110的風吹出口112，藉此氣流吐出單元120係裝設於本體110。As shown in FIG. 10, the protrusion 126 of the airflow discharge unit 120 is an inflow port 122 into which the airflow from the main body 110 flows. In this example, the protruding portion 126 is screwed and combined with the member on the side of the outlet 124. The protruding portion 126 of the airflow discharge unit 120 is fitted into the air outlet 112 of the main body 110, whereby the airflow discharge unit 120 is installed on the main body 110.

[內部的流路的構成] 　　第11圖，係表示本發明之一實施形態之流體設備的氣流吐出單元的流入口側的構成的剖面立體圖。第12圖，係本發明之一實施形態之流體設備的氣流吐出單元的流入口側的剖面圖。[Structure of the internal flow path] FIG. 11 is a cross-sectional perspective view showing the structure of the air inlet side of the air flow discharge unit of the fluid device according to one embodiment of the present invention. Fig. 12 is a cross-sectional view of the inflow port side of the air flow discharge unit of the fluid device according to an embodiment of the present invention.

本發明之一實施形態之流體設備100的氣流吐出單元120，係具備沿著流入口122的外周之2條流路200。流路200，係藉由包含複數個肋條210的壁部201及202所界定，並具有2個部位的開口部。如第12圖所示，於此例中，氣流吐出單元120係以在剖面觀察時大致左右對稱的方式具備2條流路200。The air flow discharge unit 120 of the fluid device 100 according to an embodiment of the present invention includes two flow paths 200 along the outer periphery of the inflow port 122. The flow path 200 is defined by the wall portions 201 and 202 including a plurality of ribs 210, and has two openings. As shown in FIG. 12, in this example, the air flow discharge unit 120 is provided with two flow paths 200 so as to be substantially bilaterally symmetric when viewed in cross section.

形成在相鄰之肋條210之間的壁部230，在以第12圖所示之剖面觀察時，以直線構成亦可，以曲線構成亦可。形成在相鄰之肋條210之間的壁部230不論以直線構成或以曲線構成，藉由肋條210的存在，流路200會構成為具有複數個角落。藉此，流路200，係產生細且折曲的氣流。The wall portion 230 formed between the adjacent ribs 210 may be formed by a straight line or a curved line when viewed in the cross section shown in FIG. 12. Whether the wall portion 230 formed between the adjacent ribs 210 is composed of a straight line or a curve, the presence of the rib 210 makes the flow path 200 have a plurality of corners. As a result, the flow path 200 generates a thin and curved air flow.

肋條210 ，於此例中，係如第12圖所示，以流入口側的剖面觀察時，在界定流路200之右側(內側)的壁部201及左側(外側)的壁部202，交互形成有7個。肋條210的數量及配置係不限於此，對應於氣流吐出單元120及流路200的大小決定即可。具體而言，肋條210的數量，係以一邊考慮到不致使流路200內的流體的阻力過大，一邊使流路200的流路長度盡可能地長的方式決定即可。另外，肋條210，不左右交互配置亦可。The rib 210, in this example, is shown in FIG. 12, when viewed in a cross section on the inflow side, the wall portion 201 defining the right side (inside) and the wall portion 202 on the left side (outside) of the flow path 200 interact There are 7 of them. The number and arrangement of the ribs 210 are not limited thereto, and may be determined according to the sizes of the air flow discharge unit 120 and the flow path 200. Specifically, the number of the ribs 210 may be determined so that the flow path length of the flow path 200 is as long as possible while taking into consideration that the resistance of the fluid in the flow path 200 is not too large. In addition, the ribs 210 may not be arranged alternately from side to side.

另外，肋條210，係形成為：以流入口的剖面觀察時，具有比流路的寬度W的2分之1更大的凸狀。藉由將肋條210形成為如此之大小，能夠抑制通過流路200的流體沿著氣流吐出單元120的外周的曲線流動之情事，故能夠更為確實地使流路長度L1變長。In addition, the rib 210 is formed so as to have a convex shape larger than one-half of the width W of the flow path when viewed in a cross section of the inflow port. By forming the ribs 210 to have such a size, it is possible to suppress the flow of the fluid passing through the flow path 200 along the curve of the outer periphery of the air flow discharge unit 120, so that the flow path length L1 can be more reliably increased.

流路200，與氣流吐出單元120一體形成亦可，與氣流吐出單元120分開製造，並裝設於氣流吐出單元120亦可。The flow path 200 may be formed integrally with the airflow discharge unit 120, may be manufactured separately from the airflow discharge unit 120, and may be installed on the airflow discharge unit 120.

＜安裝有氣流吐出單元120的流體設備100的作用＞ 　　從流入口122流入至氣流吐出單元120的氣流，係藉由附壁效應，沿著流出口124之上部140或下部142的任一方前進。所謂附壁效應，係指氣體或液體的噴流旁有彎曲的壁的情形，噴流朝向沿著該壁的曲面的方向流動的現象。<The role of the fluid device 100 with the airflow discharge unit 120 installed> The airflow flowing from the inlet 122 to the airflow discharge unit 120 advances along either of the upper portion 140 or the lower portion 142 of the outlet 124 by the Coanda effect. The so-called Coanda effect refers to the phenomenon in which there is a curved wall next to a jet of gas or liquid, and the jet flows toward the curved surface of the wall.

例如，在氣流沿著上部140前進時，開口部P2及開口部P4附近的壓力，會比開口部P1及開口部P3附近的壓力為低壓。因氣體係從壓力高的一方朝向低的一方流動，故於左側之流路200，會產生從開口部P1朝向開口部P2的方向的氣流。另外，於右側之流路200，會產生從開口部P3朝向開口部P4的方向的氣流。For example, when the airflow advances along the upper portion 140, the pressure near the opening P2 and the opening P4 becomes lower than the pressure near the opening P1 and the opening P3. Since the gas system flows from the higher pressure side to the lower side, the air flow in the direction from the opening P1 toward the opening P2 is generated in the flow path 200 on the left side. In addition, in the flow path 200 on the right side, an air flow from the opening P3 toward the opening P4 is generated.

若持續如此，開口部P2及開口部P4附近的壓力，與開口部P1及開口部P3附近的壓力會逆轉，而開口部P2及開口部P4附近的壓力會變得比開口部P1及開口部P3附近的壓力為高壓。因此，沿著上部140前進的氣流，會沿著下部142前進。If this continues, the pressure near the opening P2 and the opening P4 will be reversed with the pressure near the opening P1 and the opening P3, and the pressure near the opening P2 and the opening P4 will become higher than the opening P1 and the opening The pressure near P3 is high pressure. Therefore, the airflow traveling along the upper portion 140 will travel along the lower portion 142.

若氣流沿著下部142前進，則開口部P1及開口部P3附近的壓力，會比開口部P2及開口部P4附近的壓力為低壓。因氣體係從壓力高的一方朝向低的一方流動，故於左側之流路200，會產生從開口部P2朝向開口部P1的方向的氣流。另外，於右側之流路200，會產生從開口部P4朝向開口部P3的方向的氣流。When the airflow advances along the lower portion 142, the pressure near the opening P1 and the opening P3 becomes lower than the pressure near the opening P2 and the opening P4. Since the gas system flows from the higher pressure side to the lower side, the air flow in the direction from the opening P2 toward the opening P1 is generated in the flow path 200 on the left side. In addition, in the flow path 200 on the right side, an air flow from the opening P4 toward the opening P3 is generated.

若持續如此，開口部P2及開口部P4附近的壓力，與開口部P1及開口部P3附近的壓力會逆轉，而開口部P1及開口部P3附近的壓力會變得比開口部P2及開口部P4附近的壓力為高壓。因此，沿著下部142前進的氣流，會再度沿著上部140前進。If this continues, the pressure near the opening P2 and the opening P4 will reverse the pressure near the opening P1 and the opening P3, and the pressure near the opening P1 and the opening P3 will become higher than the opening P2 and the opening The pressure near P4 is high pressure. Therefore, the airflow advancing along the lower portion 142 will again advance along the upper portion 140.

藉由反覆該動作，沿著上部140的氣流X及沿著下部142的氣流Y，會持續以大致一定的週期交互切換。因此，通過氣流吐出單元120的氣流，會朝向上部140的方向及下部142的方向緩慢搖動。By repeating this action, the airflow X along the upper portion 140 and the airflow Y along the lower portion 142 will continue to alternately switch at a substantially constant period. Therefore, the airflow passing through the airflow discharge unit 120 slowly shakes toward the upper portion 140 and the lower portion 142.

本發明之一實施形態之流體設備100的氣流吐出單元120的流路200，因在界定流路200的壁部230存在有複數個肋條210，故細且折曲。因此，即便為小型化的氣流吐出單元，亦能夠使流路長度為長。若流路200的流路長度為長，則會緩慢進行前述之壓力切換所造成之氣流方向的切換。因此，橫跨氣流吐出單元120的氣流，會朝向上部140的方向及下部142的方向緩慢搖動。藉此，能夠提升搖動的效果。The flow path 200 of the air flow discharge unit 120 of the fluid device 100 according to an embodiment of the present invention has a plurality of ribs 210 on the wall 230 defining the flow path 200, so it is thin and bent. Therefore, even if it is a compact airflow discharge unit, the flow path length can be made long. If the flow path length of the flow path 200 is long, the airflow direction switching caused by the aforementioned pressure switching will be slowly performed. Therefore, the airflow across the airflow discharge unit 120 slowly shakes in the direction of the upper portion 140 and the direction of the lower portion 142. By this, the shaking effect can be improved.

然而，若採用將重點在於使氣流的方向瞬間明確地切換之習知技術，則會以曲線形成流路。因此，氣流受到強化，而氣流的切換變快。因此，使用者在體感上只會感覺到風的擴展。However, if a conventional technique that focuses on clearly switching the direction of the air flow instantaneously is adopted, the flow path is formed by a curve. Therefore, the airflow is strengthened, and the switching of the airflow becomes faster. Therefore, the user will only feel the expansion of the wind in the sense of body.

然而，本發明之一實施形態之流體設備100的氣流吐出單元120，係具有著具備前述構造的流路200。因此，於氣流吐出單元120，氣流會緩慢搖動。因此，與採用前述習知技術之情形相比，藉由使氣流緩慢搖動，使用者變得容易在體感上感受到風的"搖動"。However, the air flow discharge unit 120 of the fluid device 100 according to an embodiment of the present invention has the flow path 200 having the aforementioned structure. Therefore, in the air flow discharge unit 120, the air flow will slowly shake. Therefore, compared with the case where the aforementioned conventional technique is adopted, by slowly shaking the airflow, the user becomes more likely to feel the "shake" of the wind in the body.

如此，若使用本發明之一實施形態之流體設備100的氣流吐出單元120，則橫跨氣流吐出單元120的氣流，會朝向上部140的方向及下部142的方向緩慢搖動。因此，能夠獲得氣流的強度均勻地擴展的風，故能夠獲得來自流體設備的風的"搖動"效果。In this manner, if the airflow discharge unit 120 of the fluid device 100 according to an embodiment of the present invention is used, the airflow across the airflow discharge unit 120 will slowly rock toward the direction of the upper portion 140 and the direction of the lower portion 142. Therefore, it is possible to obtain wind in which the intensity of the airflow spreads uniformly, so that it is possible to obtain the effect of “shake” of the wind from the fluid device.

(第2實施形態) 　　第13圖，係表示本發明之第二實施形態之流體設備的氣流吐出單元的流入口側的構成的剖面立體圖。第14圖，係本發明之第二實施形態之流體設備的氣流吐出單元的流入口側的剖面圖。(Second embodiment) FIG. 13 is a cross-sectional perspective view showing the configuration of the air inlet side of the air flow discharge unit of a fluid device according to a second embodiment of the present invention. Fig. 14 is a cross-sectional view of the inflow port side of the air flow discharge unit of the fluid equipment according to the second embodiment of the present invention.

本發明之第二實施形態之流體設備500的氣流吐出單元520，與流體設備100的氣流吐出單元120，係流路的形狀不同，特別是壁部之形狀及配置的形態不同。The airflow discharge unit 520 of the fluid device 500 according to the second embodiment of the present invention is different from the airflow discharge unit 120 of the fluid device 100 in the shape of the flow path, and in particular, the shape of the wall portion and the configuration of the arrangement.

本發明之第二實施形態之流體設備的氣流吐出單元520，係具備流路600。流路600，係藉由氣流吐出單元520的外壁605及壁部630所界定。流路600，僅藉由壁部630界定亦可。如第12圖所示，於此例中，氣流吐出單元520係以在剖面觀察時大致左右對稱的方式具備2條流路200。The air flow discharge unit 520 of the fluid apparatus according to the second embodiment of the present invention includes the flow path 600. The flow path 600 is defined by the outer wall 605 and the wall portion 630 of the air flow discharge unit 520. The flow path 600 may be defined only by the wall portion 630. As shown in FIG. 12, in this example, the air flow discharge unit 520 includes two flow paths 200 so as to be substantially bilaterally symmetrical when viewed in cross section.

流路600，於此例中，係形成為具有2次折曲的形狀。具體而言，流路600，係首先從開口部P1及開口部P5沿著氣流吐出單元520的外周形成。流路600，會藉由折彎部P2及折彎部P6被折曲。藉此，流路600的方向，會轉換大致180度。並且，流路600，會藉由折彎部P3及折彎部P7被折曲。藉此，流路600的方向，會轉換大致180度。並且，流路600，係形成至開口部P4及開口部P8。流路600的折曲次數不限於此，對應於氣流吐出單元520或是流路600的大小決定即可。具體而言，流路600的折曲次數，係以一邊考慮到不致使流路600內的流體的阻力過大，一邊使流路600的流路長度盡可能地長的方式決定即可。另外，折彎部的轉換方向的角度非180度亦可，對應於氣流吐出單元520的大小、形狀決定即可。In this example, the flow path 600 is formed to have a shape bent twice. Specifically, the flow path 600 is first formed along the outer periphery of the airflow discharge unit 520 from the opening P1 and the opening P5. The flow path 600 is bent by the bending portion P2 and the bending portion P6. As a result, the direction of the flow path 600 is changed by approximately 180 degrees. In addition, the flow path 600 is bent by the bent portion P3 and the bent portion P7. As a result, the direction of the flow path 600 is changed by approximately 180 degrees. In addition, the flow path 600 is formed to the opening P4 and the opening P8. The number of bendings of the flow path 600 is not limited to this, and it may be determined according to the size of the air flow discharge unit 520 or the flow path 600. Specifically, the number of folds of the flow path 600 may be determined so that the flow path length of the flow path 600 is as long as possible while taking into consideration that the resistance of the fluid in the flow path 600 is not too large. In addition, the angle of the turning direction of the bending portion may not be 180 degrees, and it may be determined according to the size and shape of the air discharge unit 520.

壁部630，在以第14圖所示之剖面觀察時，以直線構成亦可，以曲線構成亦可。壁部630不論以直線構成或以曲線構成，藉由折彎部P2、P3、P6及P7的存在，流路600會構成為具有複數個角落。藉此，流路600，係產生大幅折曲的氣流。The wall portion 630 may be formed by a straight line or a curved line when viewed in the cross section shown in FIG. 14. Whether the wall portion 630 is composed of a straight line or a curve, the flow path 600 is configured to have a plurality of corners due to the presence of the bent portions P2, P3, P6, and P7. As a result, the flow path 600 generates a greatly bent air flow.

流路600，與氣流吐出單元520一體形成亦可，與氣流吐出單元520分開製造，並裝設於氣流吐出單元520亦可。The flow path 600 may be formed integrally with the airflow discharge unit 520, may be manufactured separately from the airflow discharge unit 520, and may be installed on the airflow discharge unit 520.

＜安裝有氣流吐出單元520的流體設備的作用＞ 　　從流入口122流入至氣流吐出單元520的氣流，係藉由附壁效應，沿著流出口124之上部140或下部142的任一方前進。例如，在氣流沿著流出口124的上部140前進時，開口部P4及開口部P8附近的壓力，會比開口部P1及開口部P5附近的壓力為低壓。因氣體係從壓力高的一方朝向低的一方流動，故於左側之流路600，會產生從開口部P1朝向開口部P4的方向的氣流。另外，於右側之流路600，會產生從開口部P5朝向開口部P8的方向的氣流。<Function of a fluid device equipped with the airflow discharge unit 520> 　　 The airflow flowing into the airflow discharge unit 520 from the inflow port 122 advances along either of the upper part 140 or the lower part 142 of the outflow port 124 by the Coanda effect. For example, when the airflow advances along the upper portion 140 of the outlet 124, the pressure near the opening P4 and the opening P8 becomes lower than the pressure near the opening P1 and the opening P5. Since the gas system flows from the higher pressure side to the lower side, the air flow in the direction from the opening P1 toward the opening P4 is generated in the flow path 600 on the left side. In addition, in the flow path 600 on the right side, an air flow from the opening P5 toward the opening P8 is generated.

若持續如此，開口部P4及開口部P8附近的壓力，與開口部P1及開口部P5附近的壓力會逆轉，而開口部P4及開口部P8附近的壓力會變得比開口部P1及開口部P5附近的壓力為高壓。因此，沿著上部140前進的氣流，會沿著下部142前進。If this continues, the pressure near the opening P4 and the opening P8 and the pressure near the opening P1 and the opening P5 will be reversed, and the pressure near the opening P4 and the opening P8 will become higher than the opening P1 and the opening The pressure near P5 is high pressure. Therefore, the airflow traveling along the upper portion 140 will travel along the lower portion 142.

若氣流沿著下部142前進，則開口部P1及開口部P5附近的壓力，會比開口部P4及開口部P8附近的壓力為低壓。因氣體係從壓力高的一方朝向低的一方流動，故於左側之流路600，會產生從開口部P4朝向開口部P1的方向的氣流。另外，於右側之流路600，會產生從開口部P8朝向開口部P5的方向的氣流。When the air flow advances along the lower portion 142, the pressure near the opening P1 and the opening P5 becomes lower than the pressure near the opening P4 and the opening P8. Since the gas system flows from the higher pressure side to the lower side, the air flow in the direction from the opening P4 toward the opening P1 is generated in the flow path 600 on the left side. In addition, in the flow path 600 on the right side, an air flow from the opening P8 toward the opening P5 is generated.

若持續如此，開口部P4及開口部P8附近的壓力，與開口部P1及開口部P5附近的壓力會逆轉，而開口部P1及開口部P5附近的壓力會變得比開口部P4及開口部P8附近的壓力為高壓。因此，沿著下部142前進的氣流，會再度沿著上部140前進。If this continues, the pressure near the opening P4 and the opening P8 and the pressure near the opening P1 and the opening P5 will be reversed, and the pressure near the opening P1 and the opening P5 will become higher than the opening P4 and the opening The pressure near P8 is high pressure. Therefore, the airflow advancing along the lower portion 142 will again advance along the upper portion 140.

藉由反覆該動作，沿著上部140的氣流X及沿著下部142的氣流Y，會持續以大致一定的週期交互切換。因此，通過氣流吐出單元520的氣流，會朝向上部140的方向及下部142的方向緩慢搖動。By repeating this action, the airflow X along the upper portion 140 and the airflow Y along the lower portion 142 will continue to alternately switch at a substantially constant period. Therefore, the airflow passing through the airflow discharge unit 520 slowly shakes toward the upper portion 140 and the lower portion 142.

本發明之一實施形態之流體設備的氣流吐出單元520的流路600，係具備複數個使氣流的方向大幅改變的折彎部，而形成為折曲複數次的形狀。藉此，即便為小型化的氣流吐出單元，亦能夠使流路長度為長。若流路600的流路長度為長，則會緩慢進行前述之壓力切換所造成之氣流方向的切換。因此，橫跨氣流吐出單元520的氣流，會朝向上部140的方向及下部142的方向緩慢搖動。藉此，能夠提升搖動的效果。The flow path 600 of the air flow discharge unit 520 of the fluid apparatus according to an embodiment of the present invention includes a plurality of bent portions that greatly change the direction of the air flow, and is formed into a shape that bends a plurality of times. Thereby, even if it is a compact airflow discharge unit, the flow path length can be made long. If the flow path length of the flow path 600 is long, the airflow direction switching caused by the aforementioned pressure switching is slowly performed. Therefore, the airflow across the airflow discharge unit 520 slowly shakes in the direction of the upper portion 140 and the direction of the lower portion 142. By this, the shaking effect can be improved.

前述實施形態之流體設備100的氣流吐出單元120及520，係具有以下特徵。The airflow discharge units 120 and 520 of the fluid device 100 of the foregoing embodiment have the following features.

流體設備100的氣流吐出單元120(520)，係具備：氣流所流入的流入口122；氣流所流出的流出口124；連結流入口122與流出口124的第1流路；以及具有2個部位的開口部，並通過該2個部位的開口部與前述第1流路連通的第2流路200(600)，該第2流路200(600)係具備於該第1流路的外側；第2流路200(600)的2個部位的開口部之間的距離L1，係比作為對於形成第1流路的周壁平行的線之連結2個部位的開口部的假想線的長度L2更長(參照第12圖)。 　　因此，於前述實施形態之氣流吐出單元120及520中，流路200及流路600的流出口124側，係藉由界定流出口124的外周部123被封閉。The airflow discharge unit 120 (520) of the fluid device 100 includes: an inflow port 122 into which the airflow flows; an outflow port 124 through which the airflow flows out; a first flow path connecting the inflow port 122 and the outflow port 124; and has two parts Through the openings of these two locations and the second flow path 200 (600) communicating with the first flow path, the second flow path 200 (600) is provided outside the first flow path; The distance L1 between the openings of the two parts of the second flow path 200 (600) is more than the length L2 of an imaginary line connecting the openings of the two parts to the line parallel to the peripheral wall forming the first flow path Long (see Figure 12). Therefore, in the airflow discharge units 120 and 520 of the foregoing embodiments, the outlet 124 sides of the flow path 200 and the flow path 600 are closed by defining the outer peripheral portion 123 of the flow outlet 124.

以上，針對本發明之較佳實施形態進行詳細說明。然而，本發明之權利範圍，係不限於此。The preferred embodiments of the present invention have been described in detail above. However, the scope of rights of the present invention is not limited to this.

例如，若使用本發明之一實施形態之流體設備100的氣流吐出單元120、520，則在毛髮量或纖維量多的情形以及毛髮或纖維長的情形，亦能夠效率良好地送風至內側的毛髮或纖維。另外，使用者能夠體感到風的移動。因此，氣流吐出單元120、520，對於吹風機、乾燥機、寵物用吹風機等特別合適。然而，氣流吐出單元120、520，亦能夠運用於類似於此之有需求的其他物品。For example, if the airflow discharge units 120 and 520 of the fluid device 100 according to an embodiment of the present invention are used, even when the amount of hair or fibers is large and when the hair or fibers are long, air can be efficiently blown to the inner hair Or fiber. In addition, the user can feel the movement of the wind. Therefore, the air flow discharge units 120 and 520 are particularly suitable for hair dryers, dryers, pet hair dryers, and the like. However, the air discharge unit 120, 520 can also be used for other items similar to this.

另外，若使用本發明之一實施形態之流體設備100的氣流吐出單元120、520，則能夠送出和緩地擴展搖動的風。因此，氣流吐出單元120、520，對於電風扇等特別合適。然而，氣流吐出單元120、520，亦能夠運用於類似於此之有需求的其他物品。In addition, if the airflow ejection units 120 and 520 of the fluid device 100 according to an embodiment of the present invention are used, the shaking wind can be sent out gently. Therefore, the airflow discharge units 120 and 520 are particularly suitable for electric fans and the like. However, the air discharge unit 120, 520 can also be used for other items similar to this.

另外，本發明之一實施形態之氣流吐出單元，為安裝於本體110的風吹出口112的前端的附件亦可，內建於流體設備100的風吹出口112亦可。In addition, the airflow discharge unit according to an embodiment of the present invention may be an accessory attached to the front end of the air outlet 112 of the main body 110, or may be built in the air outlet 112 of the fluid device 100.

另外，於本發明之一實施形態之流體設備100的氣流吐出單元120、520中，左右的流路200、600，係形成為左右對稱。藉此，氣流的控制變得容易。然而，該構成並非必須，在不會妨礙朝向上方及下方之氣流方向的切換的範圍，左右的流路200、600形成為非對稱亦可。並且，藉由設置2條流路200、600，能夠有效地使氣流上下搖動。然而，該構成並非必須，只要能夠實現朝向上方及下方之氣流方向的切換，流路200、600為1條亦可。In addition, in the air flow discharge units 120 and 520 of the fluid device 100 according to an embodiment of the present invention, the left and right flow paths 200 and 600 are formed to be bilaterally symmetrical. With this, the control of the air flow becomes easy. However, this configuration is not necessary, and the left and right flow paths 200 and 600 may be formed asymmetrically in a range that does not hinder the switching of the airflow direction toward the upper and lower sides. Furthermore, by providing two flow paths 200 and 600, the air flow can be effectively shaken up and down. However, this configuration is not necessary, and as long as the airflow direction can be switched upward and downward, only one flow path 200 or 600 may be used.
