Description

本発明は、モーターの強制熱放散構造に関し、特に、ファンモーターに応用できる強制熱放散構造に関するものである。   The present invention relates to a forced heat dissipation structure for a motor, and more particularly to a forced heat dissipation structure applicable to a fan motor.

モーターの応用範囲は広く、ファンはその一例であり、熱放散の主動装置としてよく用いられる。また、その応用範囲が異なることから、ファンモーターは、遠心式と軸流式の二種類に分けることができるが、基本的にこの二種類のファンモーターともモーターを用いてインペラを回転させ、熱散逸の効果を達成している。   The application range of the motor is wide, the fan is one example, and it is often used as a main device for heat dissipation. In addition, because of their different application ranges, fan motors can be divided into two types: centrifugal and axial flow types. Basically, these two types of fan motors use the motor to rotate the impeller and heat. Has achieved the effect of dissipation.

図１Ａは、従来技術の遠心式ファンモーターの立体図を示す。遠心式ファンモーター１は、モーター（図示せず）によって回転子１０を動かしている。遠心式ファンモーター１のインペラ１１は、回転子１０の上に接続され、回転子１０が回転する時、インペラ１１を同時に動かして空気を流動させ、熱放散の目的を達成する。図２では、従来技術の軸流式ファンモーター２を示している。同じように、モーター（図示せず）によって回転子２０を動かしている。回転子２０が回転する時、インペラ２１も回転翼を回転させて空気を流動させ、熱放散の目的を達成する。また更に、軸流式ファンモーター２は、フレーム２２を含むことができ、気流の流動を更に集中させ、熱放散の効果をより良くさせる。しかし、上述の従来技術のファンモーターが回転している時、回転子の内部は、高速の回転により、いくらかの熱量の発生を招くのを免れない。これらの熱量が仮に回転子の中に溜まれば、ファン動作の時間が長すぎることで、モーターをオーバーヒートして故障させ、ファンの使用寿命を減少する可能性がある。   FIG. 1A shows a three-dimensional view of a prior art centrifugal fan motor. The centrifugal fan motor 1 moves the rotor 10 by a motor (not shown). The impeller 11 of the centrifugal fan motor 1 is connected to the rotor 10, and when the rotor 10 rotates, the impeller 11 is simultaneously moved to flow air to achieve the purpose of heat dissipation. FIG. 2 shows a conventional axial fan motor 2. Similarly, the rotor 20 is moved by a motor (not shown). When the rotor 20 rotates, the impeller 21 also rotates the rotor blades to flow the air and achieve the purpose of heat dissipation. Still further, the axial fan motor 2 can include a frame 22 to further concentrate the flow of the air flow and improve the heat dissipation effect. However, when the above-described prior art fan motor is rotating, it is inevitable that some amount of heat is generated inside the rotor due to high-speed rotation. If these amounts of heat accumulate in the rotor, the fan operation time is too long, which may cause the motor to overheat and fail, reducing the service life of the fan.

よって、従来技術の上述の問題を解決するために、もう一種類の遠心式ファンモーター３を提供する。図２Ａを参照する。遠心式ファンモーター３は、同じように、モーター（図示せず）によって回転子３０を動かし、同時にインペラ３１もそれに伴って回転し、熱放散の目的を達成する。回転子３０は、複数の穿孔３００を含み、回転子３０が回転する時、回転子の中の熱気を複数の穿孔３００によって放出することができ、熱量が回転子の中に溜まることでモーターが故障するのを防ぐ。また、図２Ｂを参照する。軸流式ファンモーター４の回転子４０も複数の穿孔４００を含む。回転子４０が回転する時、インペラ４１をフレーム４２の中で回転させ、熱量も穿孔４００によって放出することができる。   Therefore, another type of centrifugal fan motor 3 is provided in order to solve the above-mentioned problems of the prior art. Refer to FIG. 2A. In the same manner, the centrifugal fan motor 3 moves the rotor 30 by a motor (not shown), and at the same time, the impeller 31 rotates along with it to achieve the purpose of heat dissipation. The rotor 30 includes a plurality of perforations 300, and when the rotor 30 rotates, hot air in the rotor can be discharged by the plurality of perforations 300, and the motor accumulates in the amount of heat accumulated in the rotor. Prevent failure. Reference is also made to FIG. 2B. The rotor 40 of the axial fan motor 4 also includes a plurality of perforations 400. When the rotor 40 rotates, the impeller 41 can be rotated in the frame 42 and the amount of heat can also be released by the perforations 400.

上述の従来技術のファンモーターは、確かにモーターの回転子内の熱を散逸する効果があるが、それに伴う欠点は、このタイプのファンは運転の時、ゴミ、または粒子などの異物が穿孔から回転子の中に入り易すいため、ファンモーターを一定の期間、使用した後、ゴミ、または粒子などの異物が回転軸の間に溜まったために、モーターを詰まらせてモーターを故障させる可能性がある。   The above prior art fan motors certainly have the effect of dissipating heat in the rotor of the motor, but the disadvantages associated with this type of fan are that foreign objects such as dust or particles are not allowed to perforate during operation. Because it is easy to enter the rotor, foreign matter such as dust or particles accumulates between the rotating shafts after the fan motor has been used for a certain period of time, which may clog the motor and cause the motor to malfunction. is there.

ファンの中で応用でき、前記モーターにモーターの熱量を散逸させる機能を備えさせるだけでなく、異物がモーターの回転子の中に入るのを防ぎ、モーターの使用寿命を延長することができるモーターの強制熱放散構造を提供する。   It can be applied in fans and not only provides the motor with the function of dissipating the heat of the motor, but also prevents foreign objects from entering the rotor of the motor and can extend the service life of the motor. Provides a forced heat dissipation structure.

上述の構想に基づいて、本発明は、モーターの強制熱放散構造を提供する。前記構造は、回転子シート、回転軸によって回転子シートに軸接続され、回転子が回転子シートの上で回転できるようにさせる回転子を含む。前記回転子は、円筒状から成り、その内側が回転軸に接続され、その底部は少なくとも一つの穿孔を含む回転子ハウジング、回転子ハウジングの底部外側に接続され、且つ、カバーと回転子ハウジングの間は、間隙距離を有し、カバーは、異物が穿孔の中に入るのを防ぐカバーを含む。回転子が回転する時、回転子の中の熱気は、穿孔から間隙距離を通って前記回転子ハウジングの外側に散逸する。   Based on the above concept, the present invention provides a forced heat dissipation structure for a motor. The structure includes a rotor sheet, a rotor that is axially connected to the rotor sheet by a rotation shaft and that allows the rotor to rotate on the rotor sheet. The rotor has a cylindrical shape, an inner side thereof is connected to a rotating shaft, a bottom portion thereof is connected to a rotor housing including at least one perforation, a bottom outer side of the rotor housing, and a cover and the rotor housing The gap has a gap distance and the cover includes a cover that prevents foreign objects from entering the perforations. As the rotor rotates, hot air in the rotor dissipates out of the rotor housing through the clearance distance from the perforations.

上述の構想に基づいて、本発明のカバーは、少なくとも一つの導翼、または前記回転子ハウジングの底部外側に接続された接続バーによってカバーと回転子ハウジングの間に間隙距離を持たせることができる。   Based on the above concept, the cover of the present invention can have a gap distance between the cover and the rotor housing by at least one guide vane or a connection bar connected to the outside of the bottom of the rotor housing. .

上述の構想に基づいて、本発明のカバーは、複数の導翼によって前記回転子ハウジングの底部外側に接続され、カバーと回転子ハウジングの間に間隙距離を持たせる。前記複数の導翼は、輻射状の分布からなり、各二つの導翼の間は、少なくとも一つの穿孔を有する。   Based on the above concept, the cover of the present invention is connected to the outside of the bottom portion of the rotor housing by a plurality of guide blades, and a gap distance is provided between the cover and the rotor housing. The plurality of guide blades have a radial distribution, and each of the two guide blades has at least one perforation.

上述の構想に基づいて、本発明の回転子ハウジングは、一体成型の方式によって形成される。   Based on the above concept, the rotor housing of the present invention is formed by an integral molding method.

上述の構想に基づいて、本発明の回転子ハウジングは、第一回転子ハウジングと第二回転子ハウジングが互いに嵌め合って構成され、第一回転子ハウジングの内側は、回転軸に接続され、第一回転子ハウジングの底部は少なくとも一つの穿孔を含み、第二回転子ハウジングの中心域は、導翼によってカバーに接続され、カバーと第二回転子ハウジングの間は、間隙距離を有する。   Based on the above concept, the rotor housing of the present invention is configured by fitting the first rotor housing and the second rotor housing together, and the inside of the first rotor housing is connected to the rotating shaft, The bottom of the one rotor housing includes at least one perforation, the central area of the second rotor housing is connected to the cover by guide vanes, and there is a gap distance between the cover and the second rotor housing.

本発明についての目的、特徴、長所が一層明確に理解されるよう、以下に実施形態を例示し、図面を参照にしながら、詳細に説明する。
〔実施例〕 In order that the objects, features, and advantages of the present invention will be more clearly understood, embodiments will be described below in detail with reference to the drawings.
〔Example〕

本発明の実施例は、図３Ａ〜３Ｃを参照する。図３Ａは、遠心式ファンモーター５の立体概略図を示す。図示の如く、本発明の遠心式ファンモーター５の外観は、ほぼ従来技術の遠心式ファンモーターと同じである。   Examples of the present invention refer to FIGS. FIG. 3A shows a three-dimensional schematic diagram of the centrifugal fan motor 5. As shown in the drawing, the appearance of the centrifugal fan motor 5 of the present invention is almost the same as that of the conventional centrifugal fan motor.

図３Ｂと図３Ｃを参照する。この二つの図は主に本発明の遠心式ファンモーター５の回転子５０の詳細構造を説明する立体および断面図である。図３Ａと図３Ｃを一緒に参照する。本発明の遠心式ファンモーター５は、回転子シート５５、回転子５０とインペラ５１を含む。回転子５０は、回転軸５６によって回転子シート５５の上に軸接続され、回転子５０が回転子シート５５の上で回転できるようにさせる。また、インペラ５１が回転子５０の上に接続されることから、回転子５０が回転する時、同時にインペラ５１を回転させることができ、熱放散の効果を達成する。更に一歩進んで説明する。図３Ｃを参照する。回転子５０は、回転子ハウジング５０５、カバー５０１と少なくとも一つの導翼（案内ブレード）５０２を更に含む。回転子ハウジング５０５は、円筒状であるが、その他の形状の筒状体で取って代わることもできる。回転子ハウジング５０５の内側のほぼ中央域は、回転軸５６に接続され、その底部は少なくとも一つの穿孔５００を含む。カバー５０１は、回転子ハウジング５０５の底部の外側に接続され、カバー５０１と回転子ハウジング５０５の間は、間隙距離ｄを有する。カバー５０１と回転子ハウジング５０５の底部外側の接続方式は、接続バー（図示せず）を通して実施することができる。好ましくは、本実施例のカバー５０１は、複数の導翼５０２によって回転子ハウジング５０５の底部外側に接続することができ、各導翼５０２は、遠心から外に向いて輻射状の分布を成す。複数の導翼５０２は、平板（図３Ｄ）、または弧状板（図示せず）のどちらでもよく、カバー５０１の面積範囲は、全ての穿孔５００の分布位置を覆うことができるように設計される。   Please refer to FIG. 3B and FIG. 3C. These two drawings are mainly a three-dimensional view and a sectional view for explaining the detailed structure of the rotor 50 of the centrifugal fan motor 5 of the present invention. Please refer to FIG. 3A and FIG. 3C together. The centrifugal fan motor 5 of the present invention includes a rotor sheet 55, a rotor 50 and an impeller 51. The rotor 50 is axially connected to the rotor sheet 55 by a rotation shaft 56 so that the rotor 50 can rotate on the rotor sheet 55. Moreover, since the impeller 51 is connected on the rotor 50, when the rotor 50 rotates, the impeller 51 can be rotated simultaneously, and the effect of heat dissipation is achieved. A further step will be described. Refer to FIG. 3C. The rotor 50 further includes a rotor housing 505, a cover 501, and at least one guide vane (guide blade) 502. The rotor housing 505 has a cylindrical shape, but can be replaced with a cylindrical body having another shape. A substantially central region inside the rotor housing 505 is connected to the rotation shaft 56, and its bottom includes at least one perforation 500. The cover 501 is connected to the outside of the bottom of the rotor housing 505, and a gap distance d is provided between the cover 501 and the rotor housing 505. The connection method between the cover 501 and the bottom of the rotor housing 505 can be implemented through a connection bar (not shown). Preferably, the cover 501 of the present embodiment can be connected to the outside of the bottom portion of the rotor housing 505 by a plurality of guide blades 502, and each guide blade 502 has a radial distribution outward from the centrifuge. The plurality of guide blades 502 may be either flat plates (FIG. 3D) or arcuate plates (not shown), and the area range of the cover 501 is designed to cover the distribution positions of all the perforations 500. .

本発明のモーターの強制熱放散構造の動作方式を更に下記に説明する。図３Ｃを参照する。遠心式ファンモーター５が回転を始めた時、その回転子５０は、それに伴って回転し、回転翼５１を回転させ、気圧差を発生させて空気を流動させる。その気流方向６０は、図の矢印に示されている。空気が流動する時、外部気体の流速は比較的早く、その気圧を回転子ハウジング５０５内の気圧より低くさせる。よって、ベルヌーイの法則に基づくと、回転子ハウジング５０５内の空気を穿孔５００に穿通した後、間隙距離ｄの間を通って回転子ハウジング５０５の外部に流れさせる。当然ながら、その熱気もこの方式によって流出される。その熱気流出の方向６１は、図３Ｂと図３Ｃの矢印によって示されている。更に、本発明の遠心式ファンモーター５のカバー５０１と回転子ハウジング５０５の外側に間に間隙距離ｄがあることから、その間は、複数の輻射状に分布した導翼５０２で互いに接続され、遠心式ファンモーター５が回転している時、導翼５０２もそれに伴って回転し、導翼５０２の回転は、空気を流す作用をし、より効率的に回転子ハウジング５０５内の空気を排出することができる。よって、本発明の遠心式ファンモーター５が回転している時、確実に強制熱放散の効果を有することができる。もう一方では、本発明の遠心式ファンモーター５がカバー５０１を有する設計であることから、好ましくは、その面積範囲は、全ての穿孔５００の分布位置を覆うことができるように設計される。これは、遠心式ファンモーター５が回転している時、異物を穿孔５００から回転子ハウジング５０５の中に直接入りにくくさせる。これは、遠心式ファンモーター５が異物により回転軸５６を詰まらせ、使用寿命を短縮させることがないように確保することができ、強制熱放散とモーター保護を兼ねた効果を達成する。   The operation method of the forced heat dissipation structure of the motor of the present invention will be further described below. Refer to FIG. 3C. When the centrifugal fan motor 5 starts to rotate, the rotor 50 rotates with the rotation of the centrifugal fan motor 5 to rotate the rotating blades 51 to generate an air pressure difference to flow the air. The air flow direction 60 is indicated by an arrow in the figure. When the air flows, the flow rate of the external gas is relatively fast, and the air pressure is made lower than the air pressure in the rotor housing 505. Therefore, based on Bernoulli's law, the air in the rotor housing 505 passes through the perforations 500 and then flows outside the rotor housing 505 through the gap distance d. Of course, the hot air is also discharged by this method. The hot air outflow direction 61 is indicated by the arrows in FIGS. 3B and 3C. Further, since there is a gap distance d between the cover 501 of the centrifugal fan motor 5 of the present invention and the outer side of the rotor housing 505, a plurality of radially distributed guide blades 502 are connected to each other between them. When the rotary fan motor 5 is rotating, the guide blades 502 are rotated accordingly, and the rotation of the guide blades 502 acts to flow air, and more efficiently discharges the air in the rotor housing 505. Can do. Therefore, when the centrifugal fan motor 5 of the present invention is rotating, the effect of forced heat dissipation can be reliably obtained. On the other hand, since the centrifugal fan motor 5 of the present invention is designed to have the cover 501, the area range is preferably designed to cover the distribution positions of all the perforations 500. This makes it difficult for foreign matter to enter the rotor housing 505 directly from the perforations 500 when the centrifugal fan motor 5 is rotating. This can ensure that the centrifugal fan motor 5 does not clog the rotating shaft 56 due to foreign matter and shorten the service life, thereby achieving the effect of both forced heat dissipation and motor protection.

本発明の遠心式ファンモーター５の回転子５０は、一体成型によって形成を完成することができ、好ましくは、第一回転子ハウジング５０６と第二回転子ハウジング５０７によって組合わされて成ることもできるが、これに限定するものではない。図３Ｄを参照する。本実施例で言えば、回転子ハウジング５０５は、第一回転子ハウジング５０６と第二回転子ハウジング５０７が嵌め合って接続されて成る。第一回転子ハウジング５０６の内側は、回転軸５６に接続され、第一回転子ハウジング５０６の底部は、複数の穿孔５００を含み、第二回転子ハウジング５０７の中心域は、複数の輻射状配列からなる導翼５０２によってカバー５０１に接続される。好ましくは、導翼５０２は、カバー５０１の端縁に接続される。これは、カバー５０１と第二回転子ハウジング５０７の間に間隙距離を持たせ、全体の第一回転子ハウジング５０６と第二回転子ハウジング５０７が嵌り合った後、上述の回転子ハウジング５０５と同じ効果を備える。しかし、上述の全体の回転子ハウジング５０５の成型に比べると、より製造の便利性と製造コストの節約の利点を有する。   The rotor 50 of the centrifugal fan motor 5 of the present invention can be formed by integral molding, and can be preferably formed by combining the first rotor housing 506 and the second rotor housing 507. However, the present invention is not limited to this. Reference is made to FIG. 3D. In this embodiment, the rotor housing 505 is formed by fitting and connecting a first rotor housing 506 and a second rotor housing 507. The inner side of the first rotor housing 506 is connected to the rotation shaft 56, the bottom of the first rotor housing 506 includes a plurality of perforations 500, and the central region of the second rotor housing 507 has a plurality of radial arrays. It is connected to the cover 501 by a guide blade 502 comprising Preferably, the guide blade 502 is connected to the edge of the cover 501. This is the same as the rotor housing 505 described above after a gap distance is provided between the cover 501 and the second rotor housing 507 and the entire first rotor housing 506 and the second rotor housing 507 are fitted together. Provide effects. However, compared with the above-described overall molding of the rotor housing 505, there are advantages in manufacturing convenience and cost saving.

また、本発明の実施例は、遠心式ファンモーターを例とし、前記ファンモーターの中の回転子に、カバー、穿孔と間隔距離などを有する特徴を備えさせる設計をし、異物が穿孔に穿通して回転子の中に入り、ファンモーターの寿命を短縮させるのを防ぐ目的を達成するが、これに限定するものではない。本発明の技術同様、軸流式ファンモーターの中に応用し、軸流式ファンモーターにも上述の実施例のような技術特徴を持たせることができる。更に、軸流式ファンモーターの外部にフレームを設置することができ、軸流式ファンモーターの熱放散効率をそれに伴って更に高め、産業価値を更に持たせることができる。この他、本発明はまた、ファンモーターに応用するものと限定しておらず、どの形式のモーター全てにも、その回転子を本発明の実施例で述べたような強制熱放散構造を有するように改良することができる。よって、全て、モーターに強制熱放散とモーター寿命の延長の効果を兼ね備えさせることができる。実施方式は全て本発明の実施例で述べたのと同じであり、ここでは述べない。   The embodiment of the present invention is a centrifugal fan motor as an example, and the rotor in the fan motor is designed to have a feature having a cover, a perforation distance, and the like, and a foreign object penetrates the perforation. To achieve the objective of preventing the fan motor from entering the rotor and shortening the life of the fan motor, but is not limited to this. As in the technology of the present invention, the present invention can be applied to an axial fan motor, and the axial fan motor can be provided with the technical features as in the above-described embodiments. Furthermore, a frame can be installed outside the axial fan motor, and the heat dissipation efficiency of the axial fan motor can be further increased accordingly, thereby further providing industrial value. In addition, the present invention is not limited to the application to a fan motor, and any type of motor has a rotor with a forced heat dissipation structure as described in the embodiments of the present invention. Can be improved. Therefore, it is possible to make the motor have both the effect of forced heat dissipation and the extension of the motor life. The implementation method is the same as that described in the embodiment of the present invention, and will not be described here.

以上、本発明の好適な実施例を例示したが、これは本発明を限定するものではなく、本発明の精神及び範囲を逸脱しない限りにおいては、当業者であれば行い得る少々の変更や修飾を付加することは可能である。従って、本発明が保護を請求する範囲は、特許請求の範囲を基準とする。   The preferred embodiments of the present invention have been described above, but this does not limit the present invention, and a few changes and modifications that can be made by those skilled in the art without departing from the spirit and scope of the present invention. It is possible to add. Accordingly, the scope of the protection claimed by the present invention is based on the scope of the claims.
