Description
本發明係關於一種換氣扇，尤其是一種於本體設有環牆的換氣扇。 The invention relates to a ventilation fan, in particular to a ventilation fan provided with a ring wall on the body.
請參照第1圖所示，係一種現有換氣扇9，包含一本體91，該本體91具有一第一殼體911及一第二殼體912，該第一殼體911與該第二殼體912環繞形成一空間以供容置一扇輪92。該第二殼體912遠離該第一殼體911之一側設有一環牆93，該環牆93可供結合於一隔離件(例如：天花板)，並且提供導流效果。此外，該本體91可以結合一通道連接器94，該通道連接器94連通該第一殼體911與該第二殼體912之間的空間，使得該扇輪92運轉時能夠自該環牆93外部引入空氣、以及由該通道連接器94排出空氣。 As shown in FIG. 1 , a conventional ventilating fan 9 includes a body 91 having a first housing 911 and a second housing 912 . The first housing 911 and the second housing 912 . A space is formed around to accommodate a wheel 92. A side wall 93 is disposed on a side of the second casing 912 away from the first casing 911. The ring wall 93 can be coupled to a partition (for example, a ceiling) and provides a flow guiding effect. In addition, the body 91 can be coupled to a channel connector 94 that communicates with the space between the first housing 911 and the second housing 912 such that the fan wheel 92 can operate from the ring wall 93. Air is introduced externally and air is exhausted by the passage connector 94.
其中，上述第一殼體911、第二殼體912、環牆93及通道連接器94通常為四個獨立構件，造成該換氣扇9的製程複雜，且後續組裝步驟繁多，使其製造成本較高，相關業者為了壓低成本會嘗試將部分構件合併。然而，該第一殼體911與該第二殼體912必須為二個獨立構件，否則該扇輪92及驅動該扇輪92之馬達等構件無法被安裝於該第一殼體911與該第二殼體912之間。 The first housing 911, the second housing 912, the ring wall 93, and the channel connector 94 are generally four independent members, which cause the process of the ventilating fan 9 to be complicated, and the subsequent assembly steps are numerous, resulting in high manufacturing cost. In order to reduce costs, related companies will try to merge some components. However, the first housing 911 and the second housing 912 must be two independent members, otherwise the fan wheel 92 and the motor that drives the fan wheel 92 cannot be mounted on the first housing 911 and the first Between the two housings 912.
再者，上述隔離件需開設一透孔以供該換氣扇9安裝，並且使該環牆93及該通道連接器94形成於該隔離件二側。該環牆93之最大外徑勢必會大於該透孔之孔徑，使得該環牆93可以結合於該隔離件；另一方 面，該通道連接器94係凸伸於該本體91外部，以供連接一排氣通道(例如：蛇管)，因此該通道連接器94至該本體91遠離該通道連接器94之一側的距離通常也會大於該透孔之孔徑。 Furthermore, the spacer needs to have a through hole for the ventilation fan 9 to be installed, and the ring wall 93 and the channel connector 94 are formed on both sides of the spacer. The maximum outer diameter of the annular wall 93 is bound to be larger than the aperture of the through hole, so that the annular wall 93 can be coupled to the spacer; the other side The channel connector 94 protrudes from the outside of the body 91 for connecting an exhaust passage (for example, a coil), so that the distance between the passage connector 94 and the body 91 away from one side of the passage connector 94 is It is also usually larger than the pore size of the through hole.
據此，為了確保該換氣扇9能夠穿過該隔離件之透孔，業者只能選擇將該環牆93與該第二殼體912整合為單一構件，或者選擇將該通道連接器94與該本體91整合為單一構件。換言之，該第一殼體911、該第二殼體912、該環牆93及該通道連接器94至少需為三個獨立構件，故仍然存在製造成本較高的問題，且所述三個或四個獨立構件需分別組裝，將導致該換氣扇9的組裝便利不佳。 Accordingly, in order to ensure that the ventilating fan 9 can pass through the through hole of the spacer, the operator can only choose to integrate the ring wall 93 and the second housing 912 into a single member, or select the channel connector 94 and the body. 91 is integrated into a single component. In other words, the first housing 911, the second housing 912, the ring wall 93, and the channel connector 94 need to be at least three independent members, so there is still a problem of high manufacturing cost, and the three or The four separate components need to be assembled separately, which will result in poor assembly of the ventilating fan 9.
有鑑於此，有必要提供一種進一步改良之換氣扇，以簡化換氣扇的製程及組裝步驟，有效降低換氣扇的製造成本並提升其組裝便利性。 In view of this, it is necessary to provide a further improved ventilating fan to simplify the process and assembly steps of the ventilating fan, effectively reducing the manufacturing cost of the ventilating fan and improving the assembly convenience.

為讓本發明之上述及其它目的、特徵及優點能更明顯易懂，下文特舉本發明之較佳實施例，並配合所附圖式，作詳細說明如下：請參照第2及3圖所示，本發明第一實施例之換氣扇係包含一本體1及一扇輪2。該扇輪2設置於該本體1內部。 The above and other objects, features and advantages of the present invention will become more <RTIgt; It is to be noted that the ventilating fan system of the first embodiment of the present invention comprises a body 1 and a fan wheel 2. The fan wheel 2 is disposed inside the body 1.

The first housing 11 and the second housing 12 define an accommodation space R. The fan wheel 2 is disposed in the accommodating space R, and the fan wheel 2 has an axial direction X. The air flow opening 121 extends through the accommodating space R along the axial direction X of the second housing 12 away from the side of the first housing 11 . The second casing 12 has a ring wall 13 integrally formed on one side of the air flow port 121. The ring wall 13 surrounds the air flow port 121 to provide a flow guiding effect. The ring wall 13 can be combined with a spacer D, which can be a member such as a ceiling, a wall or a system cabinet.
如第3圖所示，該本體1於該軸向X上遠離該環牆13之一側在一橫向Y上具有一最大外徑S1，該橫向Y係垂直該軸向X。該本體1具有該最大外徑S1的部分於該橫向Y上之二端分別為一第一端緣1a及一第二端緣1b。此外，該本體1於該第一殼體11或第二殼體12之外周面設有一凹部14，該凹部14在該軸向X上形成於該第一端緣1a與該環牆13之間，且該凹部14的至少一部份至該第二端緣1b之距離S2小於該最大外徑S1。 As shown in FIG. 3, the body 1 has a maximum outer diameter S1 in a lateral direction Y away from one side of the annular wall 13 in the axial direction X, and the lateral direction Y is perpendicular to the axial direction X. The two ends of the body 1 having the largest outer diameter S1 in the lateral direction Y are a first end edge 1a and a second end edge 1b, respectively. In addition, the body 1 is provided with a recess 14 on the outer peripheral surface of the first housing 11 or the second housing 12 , and the recess 14 is formed in the axial direction X between the first end edge 1 a and the ring wall 13 . And a distance S2 from at least a portion of the recess 14 to the second end edge 1b is smaller than the maximum outer diameter S1.
請一併參照第4圖所示，本發明第一實施例之換氣扇實際使用時，該扇輪2可以在該本體1之第一殼體11及第二殼體12尚未組裝前預先被設置於該第一殼體11或第二殼體12，再透過鎖固、卡扣、黏合或焊接等各式結合方式將該第一殼體11及第二殼體12相互組裝固定，使該扇輪2形成於該容置空間R中。該本體1可以組裝於該隔離件D，該隔離件D具有一透孔D1，該透孔D1沿一縱向V貫穿該隔離件D之二側表面。其中，該透孔D1具有一孔徑S0，若該孔徑S0大於或等於該本體1遠離該環牆13之一側的最大外徑S1，則僅需保持使該扇輪2之軸向X與該縱向V平行，即可將該本體1穿過該透孔D1。請參照第5圖所示，在該環牆13一併被穿過該透孔D1後，即可結合於該隔離件D。詳言之，該環牆13外周設有數個延伸部131，所述數個延伸部131在垂直該軸向X之一圓周方向上具有一外輪廓，該外輪廓之直徑S3較佳大於該最大外徑S1，故該直徑S3能夠大於該透孔D1之孔徑S0，使得該環牆13能夠經由各該延伸部131結合於該隔離件D背向該扇輪2之表面。藉此，該本體1可以透過該環牆13組裝於該隔離件D。 As shown in FIG. 4, when the ventilating fan of the first embodiment of the present invention is actually used, the fan wheel 2 can be previously set before the first housing 11 and the second housing 12 of the body 1 are assembled. The first housing 11 or the second housing 12 is assembled and fixed to each other by various combinations of locking, snapping, bonding or welding to make the fan wheel 2 is formed in the accommodating space R. The body 1 can be assembled to the spacer D. The spacer D has a through hole D1 penetrating through the two side surfaces of the spacer D in a longitudinal direction V. The through hole D1 has an aperture S0. If the aperture S0 is greater than or equal to the maximum outer diameter S1 of the body 1 away from the side of the ring wall 13, the axis X of the fan wheel 2 only needs to be maintained. The longitudinal direction V is parallel, and the body 1 can be passed through the through hole D1. Referring to FIG. 5, after the ring wall 13 is passed through the through hole D1, it can be bonded to the spacer D. In detail, the outer circumference of the ring wall 13 is provided with a plurality of extending portions 131, and the plurality of extending portions 131 have an outer contour in a circumferential direction perpendicular to the axial direction X, and the outer diameter S3 is preferably larger than the maximum The outer diameter S1 is such that the diameter S3 can be larger than the diameter S0 of the through hole D1, so that the annular wall 13 can be coupled to the surface of the fan wheel 2 facing the spacer D via the extension portion 131. Thereby, the body 1 can be assembled to the spacer D through the ring wall 13.
相對地，請參照第6圖所示，若該透孔D1之孔徑S0小於該本體1遠離該環牆13之一側的最大外徑S1，則在該扇輪2之軸向X與該縱向V平行的情況下，該本體1將無法直接穿過該透孔D1。惟，請參 照第7圖所示，本發明第一實施例之換氣扇可以被朝一第一方向旋轉一角度，使該扇輪2之軸向X相對該縱向V傾斜，藉此，該本體1包含該第一端緣1a的部分可以穿過該透孔D1。 In contrast, as shown in FIG. 6, if the aperture S0 of the through hole D1 is smaller than the maximum outer diameter S1 of the body 1 away from the side of the ring wall 13, the axial direction X of the fan wheel 2 and the longitudinal direction In the case where V is parallel, the body 1 will not be able to pass directly through the through hole D1. Only, please As shown in FIG. 7, the ventilating fan of the first embodiment of the present invention can be rotated by an angle in a first direction such that the axial direction X of the fan wheel 2 is inclined with respect to the longitudinal direction V, whereby the body 1 includes the first A portion of the end edge 1a can pass through the through hole D1.
請續參照第8圖所示，在該本體1包含該第一端緣1a的部分穿過該透孔D1後，該凹部14將可貼近該隔離件D環繞該透孔D1之內周緣。此時，由於該凹部14的至少一部份至該第二端緣1b之距離S2小於該最大外徑S1，故該距離S2可以小於該透孔D1之孔徑S0，使該本體1包含該第二端緣1b的部分也能夠穿過該透孔D1。據此，請一併參照第9圖所示，第一實施例之換氣扇可以被朝一第二方向旋轉，使該扇輪2之軸向X恢復與該縱向V平行。其中，該第二方向係與前述第一方向相反，舉例而言，若該第一方向為順時針方向，則該第二方向為逆時針方向；反之亦然。藉此，即便該透孔D1之孔徑S0小於該本體1遠離該環牆13之一側的最大外徑S1，該本體1仍然可以穿過該透孔D1。同理，在該環牆13一併被穿過該透孔D1後，該環牆13能夠經由各該延伸部131結合於該隔離件D背向該扇輪2之表面。 Referring to FIG. 8 again, after the portion of the body 1 including the first end edge 1a passes through the through hole D1, the recess 14 will be adjacent to the inner periphery of the through hole D1. At this time, since the distance S2 from the at least one portion of the recess 14 to the second end edge 1b is smaller than the maximum outer diameter S1, the distance S2 may be smaller than the aperture S0 of the through hole D1, so that the body 1 includes the first A portion of the two end edges 1b can also pass through the through hole D1. Accordingly, referring to Fig. 9, the ventilating fan of the first embodiment can be rotated in a second direction to restore the axial direction X of the fan wheel 2 parallel to the longitudinal direction V. The second direction is opposite to the first direction. For example, if the first direction is a clockwise direction, the second direction is a counterclockwise direction; and vice versa. Thereby, even if the aperture S0 of the through hole D1 is smaller than the maximum outer diameter S1 of the body 1 away from the side of the ring wall 13, the body 1 can pass through the through hole D1. For the same reason, after the ring wall 13 is passed through the through hole D1, the ring wall 13 can be coupled to the surface of the fan wheel 2 facing the spacer D via the extending portion 131.
由此可知，無論該透孔D1之孔徑S0係大於、等於或小於該本體1遠離該環牆13之一側的最大外徑S1，只要該凹部14的至少一部份至該第二端緣1b之距離S2小於該透孔D1之孔徑S0，該本體1即可穿過該透孔D1，使該第一實施例之換氣扇能夠順利被組裝於該隔離件D。 Therefore, it is known that the aperture S0 of the through hole D1 is greater than, equal to, or smaller than the maximum outer diameter S1 of the body 1 away from the side of the ring wall 13 as long as at least a portion of the recess 14 is to the second end edge. The distance S2 of 1b is smaller than the aperture S0 of the through hole D1, and the body 1 can pass through the through hole D1, so that the ventilating fan of the first embodiment can be smoothly assembled to the spacer D.
值得注意的是，在本實施例中，該本體1另包含一連接環15，該連接環15一體設置於該第二殼體12之外周面，且該連接環15中央具有一排風口151，該排風口151連通該容置空間R。該連接環15係凸伸於該本體1外部，以供連接一排氣通道(例如：蛇管)。藉此，該扇輪2運轉時，能夠由該氣流口121引入氣流，並且經由該排風口151及所述排氣通道排出空氣，使該第一實施例之換氣扇能夠提供氣流交換功能。 It is to be noted that, in this embodiment, the body 1 further includes a connecting ring 15 , the connecting ring 15 is integrally disposed on the outer circumferential surface of the second casing 12 , and the air ring 151 is disposed in the center of the connecting ring 15 . The air outlet 151 communicates with the accommodating space R. The connecting ring 15 protrudes from the outside of the body 1 for connecting an exhaust passage (for example, a coil). Thereby, when the fan wheel 2 is in operation, the airflow can be introduced from the airflow port 121, and the air is exhausted through the air outlet 151 and the exhaust passage, so that the ventilating fan of the first embodiment can provide the airflow exchange function.
由於該連接環15凸伸於該本體1外部，一般而言，該本體1具有該最大外徑S1的部分通常涵蓋該連接環15；換言之，該連接環15造成該本體1在該橫向Y上具有該最大外徑S1。在本實施例中，該本體1之第一端緣1a即形成於該連接環15，據此，請再參照第7及8圖所示，該第一實施例之換氣扇被朝該第一方向旋轉後，使該扇輪2之軸向X相對該縱向V傾斜，因此該本體1包含該連接環15的部分可以被穿過該透孔D1。該連接環15穿過該透孔D1後，該凹部14能夠貼近該隔離件D環繞該透孔D1之內周緣，使該第一實施例之換氣扇可以被朝該第二方向旋轉，進而讓該本體1穿過該透孔D1。然而，在本發明部分實施例中，該本體1可能還包含其他向外凸出的構造(例如：電路容置部、電源箱等)，均可能造成該本體1在該橫向Y上具有該最大外徑S1，因此該本體1之第一端緣1a可能非形成於該連接環15，本發明並不以此為限。 Since the connecting ring 15 protrudes outside the body 1, in general, the portion of the body 1 having the largest outer diameter S1 generally covers the connecting ring 15; in other words, the connecting ring 15 causes the body 1 to be in the lateral direction Y. It has the largest outer diameter S1. In this embodiment, the first end edge 1a of the body 1 is formed on the connecting ring 15, and accordingly, referring to the seventh and eighth embodiments, the ventilation fan of the first embodiment is directed to the first direction. After the rotation, the axial direction X of the fan wheel 2 is inclined with respect to the longitudinal direction V, so that the portion of the body 1 including the connecting ring 15 can be passed through the through hole D1. After the connecting ring 15 passes through the through hole D1, the recess 14 can be adjacent to the inner periphery of the through hole D1, so that the ventilating fan of the first embodiment can be rotated in the second direction, thereby allowing the The body 1 passes through the through hole D1. However, in some embodiments of the present invention, the body 1 may further include other outwardly convex configurations (eg, circuit housing, power box, etc.), which may cause the body 1 to have the maximum in the lateral direction Y. The outer diameter S1, the first end edge 1a of the body 1 may not be formed on the connecting ring 15, and the invention is not limited thereto.
