AIR VOLUME ADJUSTING APPARATUS CAPABLE OF INPUTTING PRE-DETERMINED AIR VOLUME USING VARIABLE RESISTANCE

摘要

PURPOSE: An air volume adjusting apparatus is provided to increase the satisfaction of a user by providing air according to the desire of the user. CONSTITUTION: An air volume adjusting apparatus includes an inputting part(110), a signal converting part(120), a controller(140), and a motor(150). Information related to the output volume of air is mechanically input to the inputting part. The signal converting part converts the mechanical input into electrical input signals. The controller determines the rotary speed of the motor using the input signals and generates controlling signals to control the motor. The rotary speed of the motor is controlled by the controlling signals. The signal converting part includes variable resistance, and both voltages of the variable resistance are used as the input signals. [Reference numerals] (140) Controller; (150) Motor
