Abstract

본 발명은 온풍 선풍기에 있어서, 모우터의 회전수를 시각적으로 다채롭게 발광다이오드로 표현하고 회전수를 직독할수도 있게 함으로써 미감의 증진효과를 얻고 사용자가 온풍 선풍기의 작동상태를 정확하게 파악할수 있도록 한 온풍선풍기의 회전수 표시 장치를 개시한다. 본 발명은 모우터의 회전축에 차단판을 설치하고 이에 인접하여 발광부와 수광부를 설치하여 줌으로써 회전축의 회전에 따라 수광부의 출력펄스의 개수가 변화하고 이를 카운터회로에 의하여 카운트한 후 마이크로 프로쎄서에 인가하여 회전수를 산출하고 이를 표시부로 표시함과 아울러 다채로운 색상으로 된 발광다이오드를 회전수에 상응하여 점등시킬수 있도록 한다. 이에 따라 본 발명은 온풍선풍기의 미감을 증진시키고 작동상태를 사용자가 정확하게 파악할수 있어 사용상의 편의를 제공할수 있게되는 효과가 있다.The present invention relates to a warm-air fan, in which the number of revolutions of a motor is represented visually by a light-emitting diode and the number of revolutions can be directly read, thereby obtaining an effect of enhancing aesthetics and allowing a user to accurately grasp the operating state of the warm- An apparatus for displaying the number of revolutions of an electric fan is disclosed. The number of output pulses of the light receiving part changes according to the rotation of the rotary shaft and is counted by a counter circuit and then applied to the microprocessor The number of revolutions is calculated and displayed on the display unit, and the light emitting diodes of various colors are turned on corresponding to the number of revolutions. Accordingly, the present invention improves the feel of the warm air fan and allows the user to accurately grasp the operating state, thereby providing convenience in use.
