Description
本發明乃是關於一種可穩定公轉之多轉子吊扇及其控制方法，特別是指一種藉由外端的單元風扇的自轉，以帶動整個吊扇產生公轉之多轉子吊扇。 The invention relates to a multi-rotor ceiling fan which can be stably revolved and a control method thereof, in particular to a multi-rotor ceiling fan which drives the entire ceiling fan to revolve by the rotation of the unit fan at the outer end.
先前技術已經有配置多個風扇的多轉子吊扇，其具有一固定軸桿、可轉動地設於固定軸桿底端的旋轉盤、多個連接臂由旋轉盤向外突出、及數個風扇分別設置於該些連接臂的末端。固定軸桿的頂端固定於天花板上。利用該些風扇的自轉所產生的扭力，而帶動旋轉盤及整個吊扇形成公轉，達到氣流廣泛吹拂以及節省電力的功效。 The prior art has a multi-rotor ceiling fan configured with a plurality of fans, which has a fixed shaft, a rotating disc rotatably disposed at the bottom end of the fixed shaft, a plurality of connecting arms protruding outward from the rotating disc, and a plurality of fans respectively set At the ends of the connecting arms. The top end of the fixed shaft is fixed to the ceiling. By utilizing the torsion generated by the rotation of the fans, the rotating disk and the entire ceiling fan are driven to form a revolution, thereby achieving wide airflow and power saving.
針對多轉子吊扇的公轉的控制與順暢，本案發明人已提出多個改良的多轉子吊扇專利，例如中華民國專利公告523047號「可穩定公轉之多轉子吊扇結構」，提出關於影響公轉速度的因素包括：吊扇之自轉速度、旋轉臂之長度、風扇馬達之重量、調節轉盤之重量(例如增加轉盤的厚度或在轉盤上加裝調節鋅塊)以及風扇馬達與旋轉臂所呈之角度等五項因素。然而，該多轉子吊扇主要在於出廠前製造設計時的安排，出廠後，有賴於使用者自行判斷公轉狀況，以外在的人為方式遙控變速而調整風扇的轉速以掌控公轉速度，而無法自動穩定公轉或在突發狀況中安全停止。 In view of the control and smoothness of the revolution of the multi-rotor ceiling fan, the inventor of the present invention has proposed a number of improved multi-rotor ceiling fan patents, such as the Republic of China Patent Bulletin No. 523047 "Multi-rotor ceiling fan structure that can be stably revolved", and proposes factors affecting the revolution speed. Including: the speed of the ceiling fan, the length of the rotating arm, the weight of the fan motor, the weight of the adjusting turntable (such as increasing the thickness of the turntable or adding a zinc block on the turntable) and the angle between the fan motor and the rotating arm factor. However, the multi-rotor ceiling fan mainly consists of the arrangement of the pre-factory design. After leaving the factory, the user relies on the user to judge the revolution status, and the externally-controlled remote control shifts the fan speed to control the revolution speed, and cannot automatically stabilize the revolution. Or stop safely in an emergency.
為著使吊扇能自行達到穩定公轉之設計，又有中華民國專利公告532431號「可公轉之多轉子吊扇之公轉速度管理機構」，揭 露一種藉由一磁通量線圈、一具有感應電磁力能力的金屬感應壁面罩體(固鎖在旋轉盤上)及一電流控制組配設在產品上，利用該磁通量線圈所產生的磁吸效應對旋轉盤產生抵減公轉力之阻力，從而達到隨意控制公轉速度之目的。然而上述多轉子吊扇之公轉速度管理機構，需要耗費電力產生磁吸效應，以產生抵減公轉力之阻力。因此由節能與環保的角度考慮而言，仍有改良的空間。 In order to enable the ceiling fan to achieve its own stable and revolving design, there is also the Republic of China Patent Announcement No. 532431, "Revolving Speed Rotor Ceiling Fan Management Mechanism" A magnetic induction wall cover body (a lock on a rotating disk) and a current control group are disposed on the product by a magnetic flux coil, and a magnetic attraction effect is generated by the magnetic flux coil The rotating disc generates a resistance against the revolving force, thereby achieving the purpose of arbitrarily controlling the revolution speed. However, the above-mentioned multi-rotor ceiling fan revolution speed management mechanism requires power to generate a magnetic attraction effect to generate resistance against the revolving force. Therefore, from the perspective of energy conservation and environmental protection, there is still room for improvement.

Although the forward motor 641 is different from the reverse motor 661, since the pitch of the second set of blades 662 is opposite to the slope of the first set of blades 642, the wind direction of the second set of blades 662 and the first set of blades 642 are both Blow down. This embodiment is for controlling the revolution speed in which the forward motor 641 and the reverse motor 661 rotate at different speeds.
請配合參考圖2，上述正向馬達641的「正向」可以是由俯視角度設為順時針方向，正向馬達641正向旋轉時產生一逆向扭力(T1)，使得單元風扇64、66及旋轉盤60，以固定桿組20為中心而產生逆向(逆時針方向)的公轉。同樣的，上述逆向馬達661的「逆向」可以是由俯視角度設為逆時針方向，逆向馬達661逆向旋轉時產生一正向扭力(T2)，使得單元風扇64、66及旋轉盤60，以固定桿組20為中心而產生正向(順時針方向)的公轉。其中本實施例的正向馬達641的轉速預設為大於逆向馬達661的轉速，因此正向扭力及逆向扭力相抵後產生一淨扭力T(T=T1-T2)，使得單元風扇64、66及旋轉盤60，以固定桿組20為中心而產生逆向(逆時針方向)的公轉。據此，控制正向馬達641與逆向馬達661的轉速，即可控制該多轉子吊扇的公轉轉速。 Referring to FIG. 2, the "forward direction" of the forward motor 641 may be a clockwise direction from a plan view angle, and a reverse torque (T1) may be generated when the forward motor 641 rotates in the forward direction, so that the unit fans 64, 66 and The rotary disk 60 is rotated in the reverse direction (counterclockwise direction) centering on the fixed rod group 20. Similarly, the "reverse direction" of the reverse motor 661 may be a counterclockwise direction from a plan view angle, and a forward torque (T2) is generated when the reverse motor 661 rotates in the reverse direction, so that the unit fans 64, 66 and the rotating disk 60 are fixed. The rod set 20 is centered to produce a positive (clockwise) revolution. The rotation speed of the forward motor 641 of the present embodiment is preset to be greater than the rotation speed of the reverse motor 661. Therefore, the positive torque and the reverse torque are offset to generate a net torque T (T=T1-T2), so that the unit fans 64 and 66 and The rotary disk 60 is rotated in the reverse direction (counterclockwise direction) centering on the fixed rod group 20.

依據上述本發明之多轉子吊扇的結構說明，本發明還提供一種可穩定公轉之多轉子吊扇的控制方法，關於多轉子吊扇結構相同於上面的描述，因此不再予以詳述。 According to the structural description of the multi-rotor ceiling fan of the present invention, the present invention also provides a control method for a multi-rotor ceiling fan which can be stably revolved. The structure of the multi-rotor ceiling fan is the same as that described above, and therefore will not be described in detail.
請參閱圖5，為本發明之多轉子吊扇的控制流程圖。多轉子吊扇的控制方法包括步驟S70，提供一可轉動地設於一固定桿組20一端的旋轉盤60；步驟S71，將至少二單元風扇64、66固定於該旋轉盤60的外側；步驟S72，啟動電源後，依使用者設定的檔速供電給該些單元風扇64、66依其各自的預設自轉速度值以產生自轉，並且相對於該固定桿組20形成公轉。上述啟動電源的供電意指由使用者按下電源鍵或風速選擇鍵的動作所啟動。若使用者開始電源而未進一步設定吊扇檔速，預設自轉速度值較佳是零。或者，預設自轉速度值可以是預設配合低檔速或者配合儲存於記憶單元76內的吊扇檔速。步驟S73，偵測該旋轉盤60的公轉速度；步驟S74，判斷使用者是否變更吊扇檔速。設定的吊扇檔速透過無線接收模組78傳輸並記憶至記憶單元76。若使用者變更吊扇檔速(Y)，步驟S74為「是」，亦即吊扇檔速值已被變更，則進行一轉換步驟。步驟S75，依據吊扇檔速，調整上述單元風扇的自轉速度至對應於上述吊扇檔速的自轉速度，並擷取獲得一預設公轉速度。其中獲得上述預設公轉速度的方式，可以是依據上述調整對照表762所預先設定的。之後，進到下述的步驟S80。若步驟S74為「否」，亦即吊扇檔速值未被變更，可以直接進到下述的步驟S80。藉此，在使用者未變更吊扇檔速的狀態下，可以省略步驟S75的轉換步驟。 Please refer to FIG. 5, which is a control flow chart of the multi-rotor ceiling fan of the present invention. The control method of the multi-rotor ceiling fan includes a step S70 of providing a rotary disk 60 rotatably disposed at one end of a fixed rod set 20; and step S71, fixing at least two unit fans 64, 66 to the outer side of the rotary disk 60; step S72 After the power is turned on, the unit fans 64, 66 are powered according to their respective preset rotation speed values according to the speed set by the user to generate the rotation, and form a revolution with respect to the fixed rod group 20. The power supply of the above-mentioned starting power source is initiated by the user pressing the power button or the wind speed selection button. If the user starts the power supply without further setting the ceiling fan speed, the preset rotation speed value is preferably zero. Alternatively, the preset rotation speed value may be preset to cooperate with the low speed or with the ceiling fan speed stored in the memory unit 76. In step S73, the revolution speed of the rotating disc 60 is detected; in step S74, it is determined whether the user changes the ceiling fan speed. The set ceiling fan speed is transmitted through the wireless receiving module 78 and memorized to the memory unit 76. If the user changes the ceiling fan speed (Y) and the step S74 is YES, that is, the ceiling fan speed value has been changed, a conversion step is performed. Step S75, adjusting the rotation speed of the unit fan to the rotation speed corresponding to the speed of the ceiling fan according to the speed of the ceiling fan, and obtaining a preset revolution speed. The manner of obtaining the preset revolution speed may be preset according to the adjustment comparison table 762. Thereafter, the process proceeds to step S80 described below. If the determination in step S74 is "NO", that is, the value of the ceiling fan speed value has not been changed, the process proceeds directly to the following step S80. Thereby, the conversion step of step S75 can be omitted in a state where the user does not change the ceiling fan speed.
步驟S80為一比較的步驟，比較偵測到的公轉速度與獲得的預設公轉速度，其中可能有三種情況，情況一為公轉速度小於預設公轉速度，情況二為公轉速度大於該預設公轉速度，情況三為公轉速度等於預設公轉速度。 Step S80 is a comparison step of comparing the detected revolution speed with the obtained preset revolution speed, wherein there may be three cases, the first case is that the revolution speed is less than the preset revolution speed, and the second case is that the revolution speed is greater than the preset revolution. Speed, case 3 is the revolution speed equal to the preset revolution speed.
在上述情況一，當上述公轉速度小於上述預設公轉速度，進到步驟S82，調整該些單元風扇64、66的轉速，以加速該旋轉盤60的該公轉速度。調整方式如同上述設定正向馬達及逆向馬達，將該些單元風扇64、66設定一組為正向旋轉，另一組為逆向旋轉，並且將正向旋轉的第一組葉片642與逆向旋轉的第二組葉片662的斜度呈反向設置，並且使該正向旋轉的馬達轉速大於該逆向旋轉的馬達轉速。上述調整的方式可以是加速正向馬達641的轉速以增加逆向扭力T1，或減小逆向馬達661的轉速以減小正向扭力T2，或者兩者同時進行，使得淨扭力T增加。 In the above case 1, when the revolution speed is less than the preset revolution speed, the process proceeds to step S82, and the rotational speeds of the unit fans 64, 66 are adjusted to accelerate the revolution speed of the rotary disk 60. The adjustment mode is the same as setting the forward motor and the reverse motor, and the unit fans 64, 66 are set to be a forward rotation, the other group is a reverse rotation, and the first group of blades 642 that rotate in the forward direction are reversely rotated. The pitch of the second set of vanes 662 is reversed and the rotational speed of the forwardly rotating motor is greater than the rotational speed of the counter-rotating motor. The above adjustment may be performed by accelerating the rotation speed of the forward motor 641 to increase the reverse torque T1, or decreasing the rotation speed of the reverse motor 661 to reduce the forward torque T2, or both, so that the net torque T is increased.
在本實施例中，在步驟S82之前，較佳的方式可以加入安全保護的判斷步驟S81，比較該公轉速度是否小於一最小公轉安全值，例如過了30秒仍未轉到一圈，也就是公轉速度每分鐘小於0.5圈，若是，則屬異常狀態，進到步驟S92，直接斷電。此種情況，有可能是吊扇遇到意外的外力阻擋或機器故障…等，為著安全緣故，吊扇自動斷電，等候使用者重新啟動或檢查。若否，也就是吊扇的公轉速度未小於(已超過)最小公轉安全值，才進行上述調整馬達自轉速度的步驟S82。在調整之後，再回到步驟S73，繼續偵測該旋轉盤60的公轉速度。 In this embodiment, before step S82, a preferred method may be added to the security protection determining step S81 to compare whether the revolution speed is less than a minimum revolution safety value, for example, after 30 seconds, it has not been transferred to a circle, that is, The revolution speed is less than 0.5 revolutions per minute, and if so, it is an abnormal state, and proceeds to step S92 to directly power off. In this case, there may be an unexpected external force blockage or machine failure of the ceiling fan, etc. For safety reasons, the ceiling fan is automatically powered off, waiting for the user to restart or check. If not, that is, the revolving speed of the ceiling fan is not less than (already exceeded) the minimum revolving safety value, the above step S82 of adjusting the motor rotation speed is performed. After the adjustment, the process returns to step S73 to continue detecting the revolution speed of the rotary disk 60.
在上述情況二，當上述公轉速度大於上述預設公轉速度，原則上是，如步驟S91，調整該些單元風扇64、66的轉速，以降低該旋轉盤60的公轉速度。上述調整的方式，可以是減少正向馬達641的轉速以減小正向扭力T1，或增加逆向馬達661的轉速以加大逆向扭力T2，或者兩者同時進行，使得淨扭力T減小。 In the above case 2, when the revolution speed is greater than the preset revolution speed, in principle, in step S91, the rotational speeds of the unit fans 64, 66 are adjusted to reduce the revolution speed of the rotary disc 60. The above adjustment may be performed by reducing the rotation speed of the forward motor 641 to reduce the forward torque T1, or increasing the rotation speed of the reverse motor 661 to increase the reverse torque T2, or both, so that the net torque T is decreased.
本實施例，在步驟S91之前，較佳的作法可以進一步設定一 安全保護的判斷步驟S90。步驟S90判斷公轉速度是否大於一最大公轉安全值。最大公轉安全值是預防多轉子吊扇的公轉超速失控，最大公轉安全值通常視多轉子吊扇的整體結構而定，例如可以設為每分鐘25轉，也就是每一公轉為2.4秒。當上述公轉速度大於預先設定的最大公轉安全值，如步驟S92所示，直接斷電，再等候使用者重新啟動。 In this embodiment, before step S91, a preferred method may further set one The security protection step S90. Step S90 determines whether the revolution speed is greater than a maximum revolution safety value. The maximum revolution safety value is to prevent the revolution of the multi-rotor ceiling fan from being out of control. The maximum revolution safety value is usually determined by the overall structure of the multi-rotor ceiling fan. For example, it can be set to 25 revolutions per minute, that is, 2.4 seconds per revolution. When the above-mentioned revolution speed is greater than the preset maximum revolution safety value, as shown in step S92, the power is directly turned off, and then the user is restarted.
對照於上述的調整對照表762，本實施例可以使調整方法更為快速，而不用反覆嘗試，藉由預先設定的調整對照表762，預先設定數組公轉速度所對應的該些單元風扇(64、66)的轉速，而直接輸出合適的控制訊號至單元風扇(64、66)，例如較佳地可以脈寬調控的方式控制該些單元風扇(64、66)的轉速。 Compared with the above-mentioned adjustment comparison table 762, the embodiment can make the adjustment method more rapid, without repeatedly trying, by setting the adjustment comparison table 762 in advance, presetting the unit fan corresponding to the array revolution speed (64, 66) The speed is directly output to the unit fan (64, 66), and the speed of the unit fans (64, 66) is preferably controlled, for example, in a pulse width modulation manner.
其中當上述公轉速度小於上述預設公轉速度的調整步驟，比較目前的公轉速度是否等於其中一組預先設定的公轉速度，若是，則依據上述調整對照表調整該些單元風扇的轉速。 When the above-mentioned revolution speed is less than the preset revolution speed, the current revolution speed is equal to one of the preset revolution speeds, and if so, the rotation speeds of the unit fans are adjusted according to the adjustment map.
在上述情況三，公轉速度等於預設公轉速度，多轉子吊扇則穩定公轉。上述公轉速度等於預設公轉速度，實際上可以允許在一設定的差值範圍內，均視為「等於」，例如將偵測到的公轉速度都四捨五入取整數值，以進行比較。 In the above case three, the revolution speed is equal to the preset revolution speed, and the multi-rotor ceiling fan is stable and revolving. The above-mentioned revolution speed is equal to the preset revolution speed, and can actually be regarded as "equal" within a set difference range. For example, the detected revolution speeds are rounded to an integer value for comparison.
補充說明的一點，依據上述的實施例，本發明還可以供使用者設定(線控或遙控)吊扇的公轉速度，例如設定為快速公轉(例如8轉)、中速公轉(例如5轉)、慢速公轉(例如3轉)。其中對應於每分鐘3轉的慢速公轉，單元風扇64、66又可以預先設定三組馬達自轉轉速，分別為每分鐘(X31，Y31)、(X32，Y32)、(X33，Y33)，而形成三種配置的風速(例如低速、中速、高速風速)供使用者選擇。其中控制每一馬達自轉轉速X(ab)值產生的T1減掉每一馬達自轉轉速Y(ab)值產生的T2之後的T值為相等，即可產生相同的公轉速度。例如較大的正向自轉X33值配合較大的逆向自轉Y33值；較小的正向自轉X31值配合較小的逆向自轉Y31值。只需要 使得兩者自轉後產生的扭力差值相等，即可控制獲得相同的公轉速度。上述使用者設定吊扇的公轉速度的步驟，在控制方法的流程中，可以補充加入步驟S74中。在步驟S75中，則進一步可以依據使用者設定的公轉速度，再擷取使用者控制的風速值。 In addition, according to the above embodiments, the present invention can also be used for the user to set (wire control or remote control) the revolution speed of the ceiling fan, for example, set to fast revolution (for example, 8 revolutions), medium speed revolution (for example, 5 revolutions), Slow revolution (for example, 3 revolutions). Corresponding to the slow revolution of 3 revolutions per minute, the unit fans 64 and 66 can preset three sets of motor rotation speeds, which are respectively (X31, Y31), (X32, Y32), (X33, Y33), and Three configurations of wind speeds (eg, low speed, medium speed, high speed wind speed) are formed for the user to select. The T value obtained by controlling T1 of each motor rotation speed X(ab) value minus T2 generated by each motor rotation speed Y(ab) value is equal, and the same revolution speed can be generated. For example, a larger forward rotation X33 value matches a larger reverse rotation Y33 value; a smaller positive rotation rotation X31 value matches a smaller reverse rotation Y31 value. only need to The difference between the torsion forces generated after the two rotations is equal, and the same revolution speed can be controlled. The step of setting the revolution speed of the ceiling fan by the user may be added to the step S74 in the flow of the control method. In step S75, the user-controlled wind speed value may be further retrieved according to the revolution speed set by the user.
本發明另外考量為著避免吊扇公轉不啟動或者啟動過慢的狀況，每當使用者切換一吊扇檔速之後，也就是使用者按下遙控器的風速按鍵之後，先將單元風扇64、66加速到最高安全自轉速度，持續運轉一段時間(例如40秒)之後，然後再各別將單元風扇64、66降到所需求的速度，也就是依據調整對照表762對照於上述該組吊扇檔速所對應的該些風扇單元風扇(64、66)的轉速。 The invention further considers that in order to avoid the situation that the ceiling fan does not start or the start is too slow, the unit fan 64, 66 is accelerated first after the user switches a ceiling fan speed, that is, after the user presses the wind speed button of the remote controller. After the maximum safe rotation speed, after continuous operation for a period of time (for example, 40 seconds), then the unit fans 64, 66 are respectively lowered to the required speed, that is, according to the adjustment comparison table 762, compared with the above-mentioned group of ceiling fan speeds. Corresponding to the rotational speed of the fan unit fans (64, 66).
請參考圖6，為本發明之多轉子吊扇確保公轉可啟動補充的控制流程圖。依上述構想，具體而言，在步驟在步驟S72供電給本發明的多轉子吊扇之後，可以***下列步驟：步驟S721，將單元風扇64、66加速到最高安全自轉速度。上述最高安全自轉速度依吊扇的結構而定，舉例而言，可以從上述調整對照表762設定的單元風扇64、66轉速值各自選擇最高的一個數值。接著，步驟S722，該些單元風扇64、66依該最高安全自轉速度，持續運轉一段預定的時間(例如40秒)。之後，接續步驟S73，偵測該旋轉盤的公轉速度，如圖5所示。 Please refer to FIG. 6 , which is a control flow chart of the multi-rotor ceiling fan of the present invention to ensure that the revolution can be started and supplemented. In view of the above, in particular, after the step of supplying power to the multi-rotor ceiling fan of the present invention in step S72, the following steps can be inserted: Step S721, the unit fans 64, 66 are accelerated to the highest safe rotation speed. The above-described maximum safe rotation speed depends on the structure of the ceiling fan. For example, the highest value of the unit fan 64, 66 rotational speed values set from the adjustment comparison table 762 can be selected. Next, in step S722, the unit fans 64, 66 continue to operate for a predetermined time (for example, 40 seconds) according to the highest safe rotation speed. Then, in step S73, the revolution speed of the rotating disc is detected, as shown in FIG. 5.
請參閱圖7，為本發明之多轉子吊扇另一種實施例的方塊示意圖。本發明也可應用於大於等於一顆轉子的風扇，原則上而言，本發明具有M個正轉方向的單元風扇及N個反轉方向的單元風扇，其中M加上N大於或等於1。如圖7所示，只設有一個單元風扇66。另一端在上一實施例的連接臂及單元風扇可以省略，或者設置一相當於該單元風扇66重量的元件，以輔助平衡。 Please refer to FIG. 7, which is a block diagram of another embodiment of a multi-rotor ceiling fan of the present invention. The present invention is also applicable to a fan having one or more rotors. In principle, the present invention has M unit fans in the forward direction and N unit fans in the reverse direction, wherein M plus N is greater than or equal to one. As shown in Fig. 7, only one unit fan 66 is provided. The connecting arm and the unit fan at the other end in the previous embodiment may be omitted, or an element corresponding to the weight of the unit fan 66 may be provided to assist the balance.
請參閱圖8，為本發明之多轉子吊扇另一種實施例的控制流程圖。配合上述M+N≧1的情況，大部分的步驟相同於圖5的步驟，其中步驟S82，當偵測公轉速度較慢時，可以藉由調高單元風扇 66以加速該旋轉盤的公轉速。步驟S91，當偵測公轉速度較快時，可以藉由調低單元風扇66以降低該旋轉盤的公轉速。 Please refer to FIG. 8, which is a control flow chart of another embodiment of the multi-rotor ceiling fan of the present invention. In the case of the above M+N≧1, most of the steps are the same as the steps of FIG. 5, wherein in step S82, when the detection revolution speed is slow, the unit fan can be adjusted. 66 to accelerate the revolution speed of the rotating disk. In step S91, when the revolving speed is detected to be fast, the unit rotation speed of the rotating disc can be lowered by lowering the unit fan 66.
本實施例的多轉子吊扇進一步提供停止公轉功能，當使用者遙控停止多轉子吊扇的公轉，執行停止公轉的訊號透過無線接收模組78傳輸至控制模組70的微處理器75，以啟動剎車機構。上述剎車機構的原理在於使旋轉盤60相對於固定桿組20及固定殼組50是停止的。若執行恢復公轉，則關閉剎車機構並回到步驟S74。 The multi-rotor ceiling fan of the embodiment further provides a function of stopping the revolving. When the user remotely stops the revolving of the multi-rotor ceiling fan, the signal for stopping the revolving is transmitted to the microprocessor 75 of the control module 70 through the wireless receiving module 78 to start the braking. mechanism. The principle of the brake mechanism described above is that the rotary disk 60 is stopped relative to the fixed rod set 20 and the fixed casing group 50. If the resumption of revolution is performed, the brake mechanism is turned off and the process returns to step S74.
關於剎車機構，請參閱圖9及圖10，為本發明具剎車機構的多轉子吊扇第一實施例局部剖視圖。圖9顯示剎車機構為解鎖狀態，圖10顯示剎車機構為剎車狀態。本實施例的剎車機構80包括一電磁致動器84藉由一架體82固定於旋轉盤60的頂面，電磁致動器84用以驅動一剎車桿88。固定殼組50的下殼罩54可以設置一剎車盤540，剎車盤540可以是呈環狀設置於下殼罩54頂面且具有多個孔洞，但其形狀不限制於此。如圖9所示，剎車桿88呈一縮回位置，藉由電磁致動器84吸回而未超過該旋轉盤60底面。或者，如圖10所示，剎車桿88可以呈一伸出位置，延伸超過該旋轉盤60底面。 Regarding the brake mechanism, please refer to FIG. 9 and FIG. 10 , which are partial cross-sectional views showing a first embodiment of a multi-rotor ceiling fan with a brake mechanism according to the present invention. Figure 9 shows the brake mechanism in an unlocked state, and Figure 10 shows the brake mechanism in a braked state. The brake mechanism 80 of the present embodiment includes an electromagnetic actuator 84 that is fixed to the top surface of the rotary disk 60 by a frame 82, and the electromagnetic actuator 84 is used to drive a brake lever 88. The lower casing 54 of the fixed casing group 50 may be provided with a brake disc 540. The brake disc 540 may be annularly disposed on the top surface of the lower casing 54 and has a plurality of holes, but the shape thereof is not limited thereto. As shown in FIG. 9, the brake lever 88 is in a retracted position and is sucked back by the electromagnetic actuator 84 without exceeding the bottom surface of the rotary disk 60. Alternatively, as shown in FIG. 10, the brake lever 88 can be in an extended position extending beyond the bottom surface of the rotating disk 60.
如圖10所示，當剎車桿88呈伸出位置，剎車桿88向下伸入剎車盤540的任一孔洞內，使得旋轉盤60相對於固定殼組50是固定的，而提供剎車功能，而停止公轉。換言之，單元風扇64、66吹向固定的方向。此實施例，剎車桿88是藉由彈簧86提供一常態向下的推力。 As shown in FIG. 10, when the brake lever 88 is in the extended position, the brake lever 88 extends downward into any of the holes of the brake disc 540, so that the rotary disc 60 is fixed relative to the fixed casing 50, and provides a braking function. And stop the revolution. In other words, the unit fans 64, 66 are blown in a fixed direction. In this embodiment, the brake lever 88 is provided with a normal downward thrust by the spring 86.
如圖9所示，當剎車桿88呈縮回位置，藉由通電給電磁致動器84吸回剎車桿88而未超過該旋轉盤60底面。使得旋轉盤60相對於固定殼組50是可旋轉的，而關閉剎車功能。當再開啟剎車機構，藉由停止供電給電磁致動器84而放鬆剎車桿88，剎車桿88藉由彈簧86，被向下推出旋轉盤60，如圖10所示。 As shown in FIG. 9, when the brake lever 88 is in the retracted position, the brake lever 88 is sucked back to the electromagnetic actuator 84 by energization without exceeding the bottom surface of the rotary disc 60. The rotating disk 60 is made rotatable relative to the fixed casing 50, and the braking function is turned off. When the brake mechanism is again turned on, the brake lever 88 is released by stopping the supply of power to the electromagnetic actuator 84, and the brake lever 88 is pushed downwardly from the rotary disk 60 by the spring 86, as shown in FIG.
請參閱圖11至圖13，為本發明具剎車機構的多轉子吊扇第二實施例局部剖視圖。圖11及圖13顯示剎車機構為啟動狀態，圖12顯示剎車機構為解鎖狀態。本實施例的剎車機構80’具有第一架體82a係固定於旋轉盤60上，一擺動卡勾88a可轉動地設置於第一架體82a、一第二架體82b係固定於旋轉盤60上、一致動馬達84a架設於第二架體82b。其中致動馬達84a具有一轉軸841及一驅動齒輪842，擺動卡勾88a連接一擺動齒輪881。驅動齒輪842嚙合於擺動齒輪881。固定殼組50的上殼罩52可以設置一剎車盤520，剎車盤520可以呈環狀固定設置於上殼罩54下方且具有多個孔洞，但其形狀不限制於此。 Please refer to FIG. 11 to FIG. 13 , which are partial cross-sectional views showing a second embodiment of a multi-rotor ceiling fan with a brake mechanism according to the present invention. 11 and 13 show the brake mechanism in the activated state, and FIG. 12 shows the brake mechanism in the unlocked state. The brake mechanism 80' of the present embodiment has a first frame body 82a fixed to the rotating disk 60, a swinging hook 88a rotatably disposed on the first frame body 82a, and a second frame body 82b fixed to the rotating disk 60. The upper and movable motor 84a is mounted on the second frame 82b. The actuating motor 84a has a rotating shaft 841 and a driving gear 842, and the swinging hook 88a is connected to a swinging gear 881. The drive gear 842 is meshed with the swing gear 881. The upper casing 52 of the fixed casing group 50 may be provided with a brake disc 520. The brake disc 520 may be fixed in a ring shape below the upper casing 54 and have a plurality of holes, but the shape thereof is not limited thereto.
如圖11及圖13所示，當啟動剎車機構80’，致動馬達84a轉動上述驅動齒輪842，進而透過擺動齒輪881以帶動上述擺動卡勾88a的勾部882向上卡入剎車盤520的任一孔洞內，使得旋轉盤60相對於固定殼組50是固定的，而提供剎車功能，而停止公轉。換言之，單元風扇64、66吹向固定的方向。 As shown in FIG. 11 and FIG. 13, when the brake mechanism 80' is actuated, the actuation motor 84a rotates the drive gear 842, and further passes through the swing gear 881 to drive the hook portion 882 of the swing hook 88a upward into the brake disc 520. Within a hole, the rotating disk 60 is fixed relative to the fixed casing 50, providing a braking function and stopping the revolution. In other words, the unit fans 64, 66 are blown in a fixed direction.
如圖12所示，當關閉剎車機構80’，致動馬達84a反向轉動上述驅動齒輪842，進而透過擺動齒輪881以帶動上述擺動卡勾88a向下離開剎車盤520，使得旋轉盤60相對於固定殼組50是可轉動的，而關閉剎車功能。 As shown in FIG. 12, when the brake mechanism 80' is closed, the actuation motor 84a reversely rotates the drive gear 842, and then transmits the swing hook 88a downwardly away from the brake disk 520 through the swing gear 881, so that the rotary disk 60 is opposite to the rotary disk 60. The fixed casing set 50 is rotatable and the brake function is turned off.
綜上所述，本發明之多轉子吊扇不僅達到節能環保的功能，在自動控制穩定公轉的方面，利用控制模組直接控制該些單元風扇的轉速，藉此以調整公轉速度。本發明不需要倚賴使用者自行調整風扇的轉速以控制公轉速度，以免控制狀況因使用者而異，或避免使用者不在而失去控制的意外。此外，本發明藉由自轉轉速的扭力制衡並非以電力產生阻抗電磁力以使公轉減速，在電力使用方式上更為節能與環保。 In summary, the multi-rotor ceiling fan of the present invention not only achieves the function of energy saving and environmental protection, but also directly controls the rotation speed of the unit fans by using the control module in the aspect of automatically controlling the stable revolution, thereby adjusting the revolution speed. The invention does not need to rely on the user to adjust the rotation speed of the fan to control the revolution speed, so as to prevent the control condition from being different from the user or avoiding the accident that the user is out of control. In addition, the torque balance of the rotation speed of the present invention is not to generate an impedance electromagnetic force by electric power to decelerate the revolution, and is more energy-saving and environmentally friendly in terms of power usage.
以上所述僅為本發明之較佳可行實施例，凡依本發明申請專利範圍所做之均等變化與修飾，皆應屬本發明之涵蓋範圍。 The above are only the preferred embodiments of the present invention, and all changes and modifications made to the scope of the present invention should be within the scope of the present invention.
