此外，較佳選擇使該轉動連接件2的板體21的第二表面21b在該軸心11的軸向上朝向該軸心11的上端11b，且該板體21上的導風孔211可以在該第二表面21b形成裸露而未被該數個葉片4所遮蔽，例如將該導風孔211開設在該第二表面21b上位於任兩相鄰葉片4之間。藉此，當該軸心11的上端11b結合於天花板時，該板體21上的導風孔211將沿著該軸心11的軸向朝向上方形成裸露，且各葉片4在該軸心11的軸向上可高於該導風孔211的開口位置。 In addition, it is preferable to select the second surface 21b of the plate body 21 of the rotary connecting member 2 to face the upper end 11b of the shaft center 11 in the axial direction of the shaft center 11, and the air guide hole 211 in the plate body 21 may be The second surface 21 b is exposed and not covered by the plurality of blades 4. For example, the air guide hole 211 is opened on the second surface 21 b between any two adjacent blades 4. Therefore, when the upper end 11 b of the shaft center 11 is coupled to the ceiling, the air guide holes 211 on the plate body 21 will be exposed upward along the axial direction of the shaft center 11, and the blades 4 are on the shaft center 11. The axial direction may be higher than the opening position of the air guide hole 211.
據由前述結構，本發明第一實施例的吊扇運作時，由於該轉動連接件2可旋轉地設於該定子1，該轉子3結合於該轉動連接件2，因此該定子1的鐵芯12可以在該線圈組13通電後，與該轉子3的永久磁鐵組32產生磁交鏈感應，以驅動該輪轂31及該轉動連接件2共同相對於該定子1產生旋轉，從而藉由結合於該轉動連接件2的該數個葉片4驅風以產生氣流。 According to the foregoing structure, when the ceiling fan according to the first embodiment of the present invention is in operation, since the rotary connection member 2 is rotatably provided on the stator 1 and the rotor 3 is coupled to the rotary connection member 2, the iron core 12 of the stator 1 After the coil group 13 is energized, magnetic linkage induction is generated with the permanent magnet group 32 of the rotor 3 to drive the hub 31 and the rotary connection 2 to rotate relative to the stator 1 so as to be combined with the stator 1. The plurality of blades 4 of the connecting member 2 are driven to blow air to generate air flow.
其中，該數個葉片4所產生的氣流會自然形成一股從中間向外(從該軸心11向各葉片4外緣)且由下而上(從該轉子3向各葉片4上方)的氣流，使得該數個葉片4旋轉時所產生的氣流能順暢地將空氣從該輪轂31內部經由該貫孔311及該導風孔211導出，並順著氣流方向流向各葉片4外緣而不會蓄積在該軸心11處。 The airflow generated by the blades 4 naturally forms an airflow from the center to the outside (from the axis 11 to the outer edges of the blades 4) and from the bottom to the top (from the rotor 3 to the blades 4 above). Airflow, so that the airflow generated when the blades 4 rotate can smoothly lead air from the inside of the hub 31 through the through holes 311 and the air guide holes 211, and flow along the airflow direction to the outer edges of the blades 4 without Will accumulate at this axis 11.
因此，本發明的吊扇可不需加裝額外的抽氣裝置，僅藉由吊扇運作時的氣流，即可即時且高效率地將定子1運作時所產生的高溫空氣帶離開輪轂31內部，確保定子1能在適當的溫度下持續工作，有助提升吊扇的散熱效率，並大幅減少高熱對吊扇構件的不良影響，使吊扇能耐久使用，達到降低維修成本及延長吊扇構件使用壽命等功效。 Therefore, the ceiling fan of the present invention does not need to be installed with an additional air extraction device, and only by the air flow during the operation of the ceiling fan, the high-temperature air generated during the operation of the stator 1 can be taken away from the interior of the hub 31 in real time and efficiently, thereby ensuring the stator 1 It can continue to work at the proper temperature, which can help improve the cooling efficiency of ceiling fans, and greatly reduce the adverse effects of high heat on the ceiling fan components, make the ceiling fans durable, reduce the maintenance costs and extend the life of the ceiling fan components.
請參照第4、5圖，其係本發明吊扇的第二實施例，本發明的第二實施例大致上同於上述的第一實施例，其主要差異在於：本發明第二實施例選擇使各葉片4的驅風部42內部呈中空狀。 Please refer to FIGS. 4 and 5, which are the second embodiment of the ceiling fan of the present invention. The second embodiment of the present invention is substantially the same as the first embodiment described above. The main difference is that the second embodiment of the present invention selects The inside of the wind repelling part 42 of each blade 4 is hollow.
詳言之，各葉片4的驅風部42內部中空而形成有一容槽421，該容槽421可以貫穿該驅風部42，以於該驅風部42的兩端分別形成一開口421a、421b，其中該開口421a朝向該板體21，該固定部41可通過該開口421a穿伸入該容槽421中，並於該驅風部42朝向該容槽421的內表面與該固定部41之間形成一氣流通道422，使得來自輪轂31內部的部分氣流能流入該氣流通道422中，並從各葉片4的外緣開口排出。據此， 本實施例可減輕各葉片4的重量，且可提供更多元化的散熱路徑，有助提升散熱效率。 In detail, the inside of the wind drive portion 42 of each blade 4 is hollow to form a containing groove 421, which can pass through the wind drive portion 42 so that two ends of the wind drive portion 42 form openings 421a and 421b, respectively. Wherein, the opening 421a faces the plate body 21, the fixing portion 41 can penetrate through the opening 421a into the receiving groove 421, and the air-driving portion 42 faces the inner surface of the receiving groove 421 and the fixing portion 41. An airflow channel 422 is formed therebetween, so that part of the airflow from the inside of the hub 31 can flow into the airflow channel 422 and be discharged from the outer edge opening of each blade 4. Accordingly, this embodiment can reduce the weight of each blade 4 and can provide more diversified heat dissipation paths, which can help improve heat dissipation efficiency.
其中，各葉片4的驅風部42可另於兩端之間設有至少一穿孔423，該穿孔423連通該氣流通道422，該穿孔423較佳設於各葉片4背向該板體21的一側，使流入該氣流通道422中的氣流可以通過該穿孔423而朝上流出至外界，故氣流不必流到葉片4外緣即可流出至外界，並被葉片4所產生的氣流向外帶，以更進一步地提升散熱效率。 Wherein, the wind-driving part 42 of each blade 4 may be provided with at least one perforation 423 between the two ends, and the perforation 423 communicates with the airflow channel 422. The perforation 423 is preferably provided on the blade 4 facing away from the plate body 21. On one side, the airflow flowing into the airflow channel 422 can flow out to the outside through the perforation 423, so the airflow can flow to the outside without flowing to the outer edge of the blade 4, and is carried outward by the airflow generated by the blade 4, In order to further improve heat dissipation efficiency.
例如但不限制地，本實施例可採用鋁擠型中空板作為各葉片4的驅風部42；透過鋁擠型方式成形各葉片4的驅風部42，僅需單一組鋁擠型模具配合裁切製程即可生產不同長度的驅風部42，並且將不同長度的驅風部42結合於該固定部41，即可形成不同長度的葉片4，使得製造不同長度的葉片4所需成本大幅降低，故可便於設計不同規格的產品以符合不同場合的使用需求。 For example, without limitation, in this embodiment, an aluminum extruded hollow plate can be used as the wind drive portion 42 of each blade 4; the air drive portion 42 of each blade 4 is formed by the aluminum extrusion method, and only a single set of aluminum extrusion mold is required to cooperate The cutting process can produce wind drive portions 42 of different lengths, and combining the wind drive portions 42 of different lengths to the fixed portion 41 can form the blades 4 of different lengths, which makes the cost of manufacturing the blades 4 of different lengths significantly. Reduced, so it can be convenient to design products of different specifications to meet the needs of different occasions.
另一方面，該板體21上的導風孔211可以與前述實施例相同設於該第二表面21b上位於任兩相鄰葉片4之間，或是如第4圖所示將該導風孔211開設在第二表面21b上位於任一葉片4與該軸心11之間，使得該導風孔211更不易受到該葉片4所遮蔽，可提升組裝時的便利性與效率。 On the other hand, the air guide holes 211 on the plate body 21 can be provided on the second surface 21b between any two adjacent blades 4 as in the previous embodiment, or the air guide holes can be shown in FIG. 4. The hole 211 is opened on the second surface 21 b between any blade 4 and the shaft center 11, so that the air guide hole 211 is more difficult to be shielded by the blade 4, which can improve the convenience and efficiency during assembly.
請參照第6、7圖，其係本發明吊扇的第三實施例，本發明第三實施例與上述第一實施例的主要差異在於：本發明第三實施例另包含一蓋板5。 Please refer to FIGS. 6 and 7, which are the third embodiment of the ceiling fan of the present invention. The main difference between the third embodiment of the present invention and the first embodiment is that the third embodiment of the present invention further includes a cover plate 5.
詳言之，該蓋板5抵接各葉片4背向該板體21的一側，使該板體21及該蓋板5能夠由該軸心11的軸向兩側共同夾持各葉片4，以提升各葉片4與該板體21之間的結合強度。另一方面，從該輪轂31內部流出的高溫空氣在通過該導風孔211後，可以從該蓋板5與該板體21之間 的空間向該板體21的外周緣流出；其中，較佳在該板體21的第二表面21b設有至少一凹陷部212，該凹陷部212兩端分別連通該導風孔211與該板體21的外周緣，使該導風孔211的正上方即使不慎被組裝至該板體21的葉片4所遮蔽，氣流仍可通過該凹陷部212流向該板體21的外周緣，確保該輪轂31內部的高溫空氣可順暢流出。 In detail, the cover plate 5 abuts the side of each blade 4 facing away from the plate body 21, so that the plate body 21 and the cover plate 5 can hold the blades 4 together on both axial sides of the shaft center 11. In order to improve the bonding strength between each blade 4 and the plate body 21. On the other hand, the high-temperature air flowing out of the hub 31 can flow out from the space between the cover plate 5 and the plate body 21 to the outer peripheral edge of the plate body 21 after passing through the air guide hole 211; Preferably, at least one recessed portion 212 is provided on the second surface 21b of the plate 21, and the two ends of the recessed portion 212 communicate with the air guide hole 211 and the outer peripheral edge of the plate 21, respectively, so that the air guide hole 211 is directly above Even if it is inadvertently shielded by the blades 4 assembled to the plate body 21, airflow can still flow to the outer periphery of the plate body 21 through the recessed portion 212 to ensure that the high-temperature air inside the hub 31 can flow out smoothly.
另請參照第8圖，在設有該蓋板5的其他實施例中，也可以在該蓋板5上設有貫穿狀的至少一通氣孔51，並於安裝該蓋板5時，使該通氣孔51連通該導風孔211。據此，一部分從該導風孔211排出的高溫空氣可直接向該板體21的外周緣逸散，另一部分的高溫空氣則可通過該通氣孔51而流到該蓋板5的上方，並被葉片4所產生的氣流向外帶，以維持良好的散熱效率。 Referring also to FIG. 8, in other embodiments in which the cover plate 5 is provided, the cover plate 5 may also be provided with at least one vent hole 51 penetrating through the cover plate 5. The air hole 51 communicates with the air guide hole 211. According to this, a part of the high-temperature air discharged from the air guide hole 211 can be directly dissipated toward the outer peripheral edge of the plate body 21, and another part of the high-temperature air can flow above the cover plate 5 through the vent hole 51, and The airflow generated by the blade 4 is taken outward to maintain good heat dissipation efficiency.
請參照第9、10圖，其係本發明吊扇的第四實施例，本發明的第四實施例與前述各實施例的主要差異在於：本發明第四實施例的各葉片6未設置固定部，而是直接將各葉片6的驅風部61組裝結合於該轉動連接件2的板體21。 Please refer to FIGS. 9 and 10, which are the fourth embodiment of the ceiling fan of the present invention. The main difference between the fourth embodiment of the present invention and the foregoing embodiments is that each blade 6 of the fourth embodiment of the present invention is not provided with a fixing portion. Instead, the air-driving portion 61 of each blade 6 is directly assembled and combined with the plate body 21 of the rotating connecting member 2.
詳言之，各葉片6由驅風部61的一端結合於該板體21，而該驅風部61的另一端延伸超出該板體21的外緣，該驅風部61內部中空而形成有一容槽611；本實施例可減輕各葉片6的重量，並提升將各葉片6組裝至該板體21時的組裝便利性與效率。 In detail, one end of each blade 6 is coupled to the plate body 21 by one end of the wind drive portion 61, and the other end of the wind drive portion 61 extends beyond the outer edge of the plate body 21, and the inside of the wind drive portion 61 is hollow to form a The receiving groove 611; this embodiment can reduce the weight of each blade 6 and improve the assembly convenience and efficiency when assembling each blade 6 to the plate body 21.
又，該驅風部61結合於該板體21的一側設有一穿孔612,該穿孔612連通該容槽611，且該穿孔612連通該導風孔211及該貫孔311。據此，該輪轂31內部的高溫空氣可依序通過該貫孔311、該導風孔211及該穿孔612而流入該驅風部61的容槽611，再從各葉片6的外緣開口排出。其中，由於該數個葉片6運作時所產生的氣流方向是從中間向外(從該軸心11向各葉片6外緣)，故較佳可將該驅風部61朝向該軸心11的一端設 為封閉狀，例如將該容槽611朝向該軸心11的開口塞住，使流入該容槽611的氣流無法朝內流向該軸心11，令大部分的高溫空氣都能在較短的時間內順應氣流方向朝外流出，有助提升整體散熱效率。 In addition, a side of the board 21 is provided with a perforation 612, the perforation 612 communicates with the receiving groove 611, and the perforation 612 communicates with the air guide hole 211 and the through hole 311. According to this, the high-temperature air inside the hub 31 can sequentially pass through the through hole 311, the air guide hole 211, and the perforation 612, flow into the receiving groove 611 of the wind drive portion 61, and then be discharged from the outer edge opening of each blade 6. . Among them, since the direction of the air flow generated when the plurality of blades 6 are operating is from the middle to the outside (from the axis 11 to the outer edge of each blade 6), it is preferable that the wind drive portion 61 be directed toward the axis 11 One end is closed. For example, the opening of the container groove 611 toward the shaft center 11 is plugged, so that the airflow flowing into the container groove 611 cannot flow inward to the shaft center 11, so that most of the high-temperature air can be kept short. It follows the direction of the airflow and flows outwards within the time, which helps improve the overall heat dissipation efficiency.
綜上所述，本發明的吊扇，可利用會隨輪轂及板體轉動的貫孔與導風孔，加劇輪轂內、外的壓力差，以搭配吊扇運作時所產生的氣流，加強輪轂內部高溫空氣排出的效率，並使高溫空氣能順應氣流朝葉片外緣流動而不會蓄積在軸心處。因此，本發明的吊扇可不需加裝額外的抽氣裝置，僅藉由吊扇運作時的氣流，即可即時且高效率地將定子運作時所產生的高溫空氣帶離開輪轂內部，確保定子能在適當的溫度下持續工作，有助提升吊扇的散熱效率，並大幅減少高熱對吊扇構件的不良影響，使吊扇能耐久使用，達到降低維修成本及延長吊扇構件使用壽命等功效。 In summary, the ceiling fan of the present invention can use the through holes and air guide holes that will rotate with the hub and the plate to increase the pressure difference between the inside and outside of the hub, and match the airflow generated during the operation of the ceiling fan to strengthen the high temperature inside the hub The efficiency of air exhaustion enables the high-temperature air to flow toward the outer edge of the blade in accordance with the airflow without accumulating at the axis. Therefore, the ceiling fan of the present invention does not need to be equipped with an additional air extraction device, and only by the air flow during the operation of the ceiling fan, the high-temperature air generated during the operation of the stator can be taken away from the interior of the hub in a timely and efficient manner, ensuring that the stator can Continued work at an appropriate temperature can help improve the cooling efficiency of the ceiling fan and greatly reduce the adverse effects of high heat on the ceiling fan components, make the ceiling fan durable, and reduce the maintenance costs and extend the life of the ceiling fan components.
