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.

Claims

1. A grille controlling apparatus for an indoor ventilator that has a grille cover disposed on the front side of said indoor ventilator and forming a plurality of grille holes on the plate surface thereof, and a grille casing disposed on the rear side of said grille cover, said apparatus including:

at least one damper disposed on the rear side of said grille casing, for opening/closing an air flow path;

a damper driving part disposed on the one side of said grille casing, for driving said damper up to an opening/closing position;

a power supply part for supplying power to said damper driving part;

a temperature sensor for sensing an indoor temperature;

a manipulating part for driving said damper driving part and/or for selecting a predetermined driving mode of said damper driving part in accordance with the sensed indoor temperature of said 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 said temperature sensor such that it controls the driving of said damper driving part; and

an electronic circuit board provided with an operation display part on which the operation of the machinery is displayed.

2. The grille controlling apparatus according to claim 1, wherein said damper is formed by a pair of plate members that are turned on the upper and lower areas of said air flow path, and said damper driving part comprises a driving motor disposed on said grille casing for opening/closing one of said pair of dampers and an engaging part adapted to engage said pair of dampers.

3. The grille controlling apparatus according to claim 2, wherein said engaging part comprises an engaging arm that has the both sides in a length direction rotatably coupled with said pair of dampers, and a manually operated protrusion that is extended from the one area of said engaging arm to the outside of said grille cover in such a manner as to manually manipulate the opening/closing of said damper.

4. The grille controlling apparatus according to claim 1, wherein said damper comprises a plate member that is disposed on the rear surface of said grille cover in such a way as to move back and forth between a position where said grille holes are closed and another position where said grille holes are opened and a solenoid that is formed on said grille casing for moving said damper back and forth.

5. The grille controlling apparatus according to claim 1, wherein said manipulating part comprises a wireless remote controller with opening and closing buttons for said damper and a plurality of mode selecting buttons for the driving modes, and a signal receiver disposed on the one area of said grille casing for sending the manipulating signal from said wireless remote controller to said control part.

6. The grille controlling apparatus according to claim 5, wherein said control part controls, if the manipulating signal for the opening or closing button from said manipulating part is received, the driving of said damper driving part such that said damper is opened or closed.

7. The grille controlling apparatus according to claim 5, wherein said control part is provided with a plurality of appropriate indoor temperature ranges corresponding to the mode selecting buttons that are previously set, and said control part controls the opening/closing of said damper such that the indoor temperature sensed by said temperature sensor is in the indoor appropriate temperature range according to the modes selected by the mode selecting buttons.
