KR970045606A - Fan rotation angle control device - Google Patents

Abstract

The present invention relates to an apparatus for controlling the rotation angle of a fan, comprising: a rotating body driving unit 50 for rotating a rotating body 55 including a rotating blade 14, a safety grill 16, and a wing driving unit 13. In the fan for operating the rotating body 55 on the basis of the control mode signal set in the control function setting unit 20, the setting of the rotation angle control mode for setting the range of the rotation angle of the rotating body 55 20a and a control function setting unit 20 further including a rotation angle range designation button 20b and a light emitting unit installed at the lower end of the rotating body 55 to emit light when performing the operation for the rotation angle control mode. 25, an optical sensing unit 30 installed at a predetermined portion of the pedestal 12 corresponding to the light emitting unit 25 to sense light from the light emitting unit 25, and the rotation angle control mode is set. If the rotation angle range is specified by the control function setting unit 20, the rotation angle range The microcomputer 35 stores data and controls the light emitting unit 25 to emit light, and controls the rotatable body 55 to rotate within the rotation angle range, under the control of the microcomputer 35. A data storage unit 45 for storing rotation angle range setting data; a display signal processor 60 for signal processing the rotation angle range setting data under the control of the microcomputer 35 when the rotation angle control mode is set; And a display unit 65 for displaying a signal from the display signal processing unit 60 as a selection menu, wherein the rotating body of the fan rotates clockwise from counterclockwise or counterclockwise from clockwise. Since the user can set the rotation angle range of two points arbitrarily while the user views the rotation angle range setting data displayed on the display, the user can visually set the desired rotation angle range. By being said to be able to set up, there is no need to rotate, which can save power wasted effect.
