Grille controlling apparatus for indoor ventilator

Abstract

Disclosed is a grille controlling apparatus for an indoor ventilator that senses an indoor temperature in a building such that it can control the operation of the grille mounted on the indoor ventilator. The apparatus includes a grill cover that is disposed on the front side of the indoor ventilator, a grille casing that is disposed on the rear side of the grille cover, at least one damper disposed on the rear side of the grille casing, for opening/closing an air flow path, a damper driving part for driving the damper up to an opening/closing position, a power supply part for supplying power to the damper driving part, a temperature sensor for sensing an indoor temperature, a manipulating part for selecting a predetermined driving mode of the damper driving part in accordance with the sensed indoor temperature of the temperature sensor, a control part for comparing a manipulating signal from the manipulating part and/or the selected driving mode with the sensed indoor temperature of the temperature sensor such that it controls the driving of the damper driving part, and an electronic circuit board provided with an operation display part on which the operation of the machinery is displayed. Thereby, the indoor temperature can be appropriately maintained at a pleasant temperature, thereby enabling an amount of energy to be consumed to be considerably saved.
