201233910 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種水平式對流扇及其框座，特別是一 種呈徑向入風及出風之水平式對流扇及其框座。 【先前技術】 請參照第1及2圖所示，習知的水平式對流扇結構係 包含有一框座91、一扇輪92及一蓋板93。該框座91具有 一底板911 ’該底板911上設有一轴座912 ’該底板911之 其中二相鄰侧邊分別為一入風側913及一出風侧914，該 入風侧913及出風側914係以一分流部915區隔，且該底 板911另延伸有一侧牆916，該侧牆916二端係分別連接 該入風側913及出風側914。該扇輪92係可轉動的設於該 轴座912。該蓋板93係設置於該框座91，並可透過固定元 件94裝設於該分流部915及側牆916頂面。故當該扇輪 92旋轉時，係可驅使空氣經由該入風侧913吸入，並由該 出風侧914吹出。 惟，習知水平式對流扇之入風側913及出風側914係 僅由一分流部915區隔，使得該入風側913及出風侧914 太過於接近，且該入風側913及出風侧914之間亦無其它 用以分隔氣流的設計，所以經由該出風侧914吹出之空氣 容易受到該入風側913之吸力影響，尤其是該出風侧914 鄰近該分流部915之空氣更容易因為該入風側913之吸力 作用而形成一反向氣流區域（Z)，該反向氣流區域（z) 内之空氣會偏向該入風側913，且被該扇輪92回吸’不僅 201233910 造成該出風側914之排風量減少，被回吸之空氣也容易與 該入風侧913所吸入之空氣互相推擠而造成擾流，進而影 響該入風側913之吸風順暢性’降低其進風量。而且，該 習知框座91之出風側914幾乎完全開放，使該出風側914 所吹出之空氣容易朝向四周擴散，故無法集中出風且容易 造成風量及風壓降低。 【發明内容】

Referring to FIG. 4, when the bottom plate of the present invention is rectangular, a reference line may be further defined in the frame, and the reference line (Η) passes through the first end 1221 of the blocking portion 122 and The two ends 1222 are radially extended from the center of the shaft seat 111 of the frame 1 - a reference line (BG), a - an auxiliary line, and a second auxiliary line (b2), wherein the reference line and the first auxiliary line ( B,) and the second auxiliary line (B2) both extend toward the bottom plate u of the test line (Η) and the reference line ((5)) is straight to the reference line (Η) 'the first auxiliary line (Βι And the second auxiliary line (By both pass and the reference line (Η)' and the first lion line (Βι) and the second auxiliary line (5) are farther away from the reference line 122 (Β) The first auxiliary line (B1) and the read reference line (Bq) have a -first angle θ i 'the second auxiliary line (b2) and the reference line (Β.) have a second missing angle Θ 2 And the end angle 1231 of the diverting portion 123 is located within the interval of the first auxiliary line (0 and the second auxiliary line (B2), wherein the first angle θα may be 5 degrees, and the second refresh angle They The angle can be %. The 'black fan wheel 2 is rotatably mounted on the frame seat 11 of the frame 1 and 201233910 can be driven by the motor to rotate the wheel 2 to drive air through the air inlet 13 It is blown out by the air outlet 14. However, the use of the motor to drive the wheel 2 is known to those of ordinary skill in the art and is not a feature of the present invention, and will not be described below. 3 is disposed on the frame 1 and covers the fan wheel 2, and the cover plate 3 can be mounted on the top surface of the side wall 12 of the frame 1 by using the fixing member 4. When the horizontal convection fan of the present invention is implemented, Since the air inlet 13 and the air outlet 14 are separated by the blocking portion 122, and the blocking portion 122 is extended from the first end 1221 adjacent to the air inlet 13 toward the second end 1222, the The air taken in by the air inlet 13 is isolated from the air blown by the air outlet 14 to avoid mutual interference to form a turbulence flow, and the diverting portion 122 guiding surface 1232 can further guide the air to be smoothly blown through the air outlet 14 Prevent the air at the air outlet 14 from being again used by the fan wheel 2 Therefore, the air blown through the air outlet 14 is not easily affected by the suction force of the air inlet 13 'the reverse air flow at the air outlet 14 can be reduced to avoid affecting the air suction smoothness of the air inlet 13 and improving In addition, referring to Figure 5, the figure (L1) is the wind volume and wind pressure test data curve of the conventional horizontal type diagonal flow fan, and the figure (L2) is the air volume and wind pressure test of the present invention. The data curve. It can be seen from the test data that when the blocking portion 122 and the diverting portion 123 of the present invention can prevent the air at the air outlet 14 from being inhaled again by the fan wheel 2, especially when the end angle 1231 of the diverting portion 123 is located at the When the auxiliary line (B) is within the interval of the second auxiliary line (b2), the blocking portion 122 and the diverting portion 123 can more significantly reduce the reverse air flow at the air outlet 14. Therefore, the air volume of the present invention and Wind pressure is significantly improved compared to conventional horizontal convection fans. 201233910 Please refer to FIG. 6 , the frame 5 of the second embodiment of the present invention also has a bottom plate 51 , a shaft seat 511 , a side wall 52 , a flow guiding portion 521 , a wind guiding surface 5211 , a blocking portion 522 , and a first end 5221 . Structural features such as the second end 5222, the diverting portion 523, the end angle 5231, the guiding surface 5232, the leeward surface 5233, the air inlet 53 and the air outlet 54. Compared with the foregoing first embodiment, the bottom plate 51 of the second embodiment has an irregular shape, and the air inlet 53 and the air outlet 54 are located on opposite sides of the bottom plate 51. In order to define a preferred position of the diverting portion 523, when the bottom plate 51 of the present invention has an irregular shape, a reference line (B〇) and an auxiliary line (b3) may be radially extended from the center of the shaft seat of the frame 5. The reference line (B〇) passes through the second end 5222 of the blocking portion 522, and the auxiliary line (B3) passes through the air outlet 54, and the auxiliary line (B3) and the reference line (B〇) The end angle 5231 of the diverting portion 523 is located at an interval between the reference line (Β〇) and the auxiliary line (3⁄4) to effectively reduce the reverse airflow at the air outlet 54, wherein The angle of the angle 0 can be 45 degrees. As described above, the horizontal convection fan of the present invention is provided with the blocking portions 122, 522 and the diverting portions 123, 523 at the air outlets 14, 54 of the bottom plates 11, 51 of the frame bases 1, 5, wherein the blocking portion 12: 2, 522 can surely isolate the air sucked by the air inlets 13, 53 from the air blown by the air outlets 14, 54 to avoid mutual interference and form a spoiler. Moreover, the flow dividing portions 123 and 523 can further guide the air to be smoothly blown through the air outlets 14 and 54 to prevent the air at the air outlets 14 and 54 from being sucked again by the fan wheel 2, and the air blown by the air outlets 14 and 54 is prevented from being subjected to the air blown by the air outlets 14 and 54. The suction of the air inlets 13, 53 affects the situation of 'reducing the reverse airflow' to avoid the turbulence and the effect of increasing the air volume and the wind pressure 201233910. Moreover, the diverting portions 123 and 523 of the present invention can appropriately limit and guide the size and direction of the air outlets 14 and 54 to prevent the air blown through the air outlets 14 and 54 from diffusing toward the surroundings to achieve concentrated airflow. And enhance the effect of air volume and wind pressure.
