Description
本創作係有關於一種雙扇葉電風扇，尤指一種利用直流馬達驅動第一及第二扇葉作動，以達到減少晃動、噪音及減輕負載、節省電能等效益之雙扇葉電風扇。The present invention relates to a double-blade electric fan, and more particularly to a double-blade electric fan that uses a DC motor to drive the first and second blades to achieve the effects of reducing sloshing, noise, reducing load, and saving power.
按，夏季氣候炎熱難耐，若無電風扇等協助散熱降溫，則難以靜心工作或休憩等，傳統風扇主要由一馬達帶動一扇葉轉動產生氣流，由於一扇葉僅能產生單一氣流，故可造成空氣對流效果有限，無法提供有效送風散熱功效，若設置多台電風扇則又佔空間及耗費電力。According to the summer climate, it is hard to bear. If there is no electric fan to help cool down, it is difficult to work or rest. The traditional fan is mainly driven by a motor to generate airflow. Since a blade can only generate a single airflow, it can cause The air convection effect is limited, and it cannot provide effective air supply and heat dissipation. If multiple electric fans are installed, it takes up space and consumes electricity.
於是，乃有業者研發出一種雙扇葉風扇，其主要設有一支撐單元，並於該支撐單元上組設有一交流馬達，該交流馬達係具有一貫穿之轉軸，並於該轉軸其第一端及第二端分別結合有二扇葉，藉此，當該交流馬達帶動二扇葉轉動時，即能產生兩股軸向氣流，以提高送風、散熱效果。然，該現有雙扇葉風扇雖可增加風力及提高散熱性，但於實際使用上卻發現該雙扇葉風扇於運轉時有吹風量不均情形，更會產生極大晃動，與發出相當大的噪音，究其原因乃因為該現有雙扇葉風扇係採交流馬達作為其動力來源，由於交流馬達其工作頻率為正弦波，於正弦波的高諧波成分重疊下，即易造成交流馬達作動時產生振動及發出異音，又透過帶動雙扇葉運轉的加乘作用，更使其振動與異音等問題顯著化，除此之外，交流馬達於使用上更有負載大、耗電量高及成本高等缺失，不符合節能效益，故現有雙扇葉風扇之實用性不佳，有改善必要性。Therefore, a manufacturer has developed a double-blade fan, which is mainly provided with a supporting unit, and an AC motor is arranged on the supporting unit. The AC motor has a rotating shaft extending through the first end of the rotating shaft. And the second end is combined with two blades, respectively, whereby when the AC motor drives the two blades to rotate, two axial airflows can be generated to improve the air supply and heat dissipation effects. However, although the existing double-blade fan can increase the wind power and improve the heat dissipation, it is found in the actual use that the double-blade fan has uneven air blowing during operation, and it also has a great sway, and is quite large. The reason for the noise is that the existing double-blade fan adopts an AC motor as its power source. Since the AC motor operates at a sine wave, when the harmonic components of the sine wave overlap, it is easy to cause the AC motor to operate. Vibrating and emitting abnormal sounds, and by multiplying the double-blade operation, the vibration and abnormal sounds are significantly more prominent. In addition, the AC motor is more loaded and consumes more electricity. And the lack of high cost, does not meet the energy-saving benefits, so the existing dual-blade fan is not practical, there is a need to improve.
緣是，本創作人有鑑於現有雙扇葉風扇於實施使用上仍有上述諸多缺失，乃藉其多年於相關領域的製造及設計經驗和知識的輔佐，並經多方巧思，研創出本創作。The reason is that this creator has many of the above-mentioned shortcomings in the implementation of the existing double-blade fan. It is based on years of manufacturing and design experience and knowledge in related fields, and through various ingenuity, research and creation of this creation. .
