Abstract

A motorized air register, air diffuser or vent for HVAC systems in commercial and residential applications comprises a supporting frame abutting a floor, wall or ceiling and a second depending frame for enclosing a damper. The damper is motor driven from a first fully open position to a second fully closed position. The damper can be controlled remotely from a wall consol or in accordance with thermostat logic.

Claims

1. A motorized air vent for controlling an air flow, said motorized air vent comprising:

a. A first rectangular frame adapted for supporting placement in a rectangular hole within one of a floor surface, a wall surface and a ceiling surface;

b. A rectangular bulkhead depending from the first rectangular frame and dimensioned to fit snuggly within said rectangular hole while allowing easy removal of the motorized air vent from said rectangular hole;

c. A first fixed matrix of equally spaced and parallel horizontal and vertical members forming a plurality of equally sized rectangular apertures for air distribution mounted within said first rectangular frame;

d. A second sliding matrix matching said first fixed matrix and carried by a series of tabs mounted within said rectangular bulkhead beneath the first fixed matrix so that when said second matrix slides to coincide with the first matrix the motorized air vent is full open and when the second matrix slides to an offset position with respect to the first matrix the motorized air vent is fully closed and wherein the second sliding matrix has a bottom surface having a cam-complementary recess comprising a circular indentation enclosing a space having a closed top surface and an open bottom disposed in the centre thereof for accepting a rotating cam head for sliding the second matrix;

e. A mounting plate disposed beneath said cam-complementary recess and centrally attached width-wise to the bulkhead, said mounting plate having a top surface, a bottom surface and a centrally disposed aperture beneath the cam-complementary recess;

f. An electric motor mounted to said bottom surface of the mounting plate and centrally disposed within the vent, said electric motor having a shaft protruding through said centrally disposed aperture for attachment to a cam body having said rotating cam head disposed on said top surface of the mounting plate, wherein the rotating cam head is disposed within the cam-complementary recess;

g. A battery mounted to the bottom surface of the mounting plate adjacent to said electric motor and in communication with the electric motor; and

,

h. a remotely programmable wireless controller mounted to the top surface of the mounting plate for electric motor control.

2. The motorized air vent of claim 1 wherein said remotely programmable wireless controller communicates with one of a wall mounted consol and a thermostat is radio frequency.
