Abstract

A portable remote wireless control for establishing different temperatures in separate portions of a building. The remote control not only regulates hot and cold airflow through rotatable damper vanes in one or more diffusers, but it also recharges the batteries that power the wireless receiver, servomotor and servomotor controls that selectively rotate the damper vanes. Damper vane rotation regulates air flow from the diffuser to control the temperature in the portion of the building. The damper vanes, moreover, are of a light plastic with a marginal band of a foam material to enable the vanes to rotate silently and freely also to form a seal that eliminates a great deal of air seepage past the individual vanes.

Claims

1. A heating and cooling diffuser for an air duct comprising a plurality of generally parallel damper vanes forming gaps therebetween said damper vanes being ganged for joint motion, a servomotor for controlling said joint damper vane motion, a linkage coupling said servomotor to at least one of said damper vanes for moving said ganged damper vanes, and a radio receiver and servomotor control for selectively activating said servomotor.

2. A heating and cooling diffuser according to claim 1 further comprising a battery access hatch for accommodating a battery therein.

3. A heating and cooling diffuser according to claim 1 wherein each of said damper vanes has a foam covering on each of the respective perimeters thereof to reduce noise and air seepage past said damper vanes.

4. A remote wireless thermostat and battery control for a heating and cooling air duct system comprising an electrical plug for selective insertion into a socket, a display for showing the temperature measured by the thermostat, at least one switch for setting the thermostat to a predetermined temperature and displaying said predetermined temperature on selective activation of said switch, a battery recharger coupled to the remote control for recharging air duct system batteries, a remote control transmitter for transmitting wireless signals that correspond to said displayed predetermined temperature and means for electrically coupling said plug to said battery recharger and to said remote control transmitter.

5. A wireless air heating and cooling system for controlling the air temperature at more than one predetermined temperature within different zones of a structure comprising a plurality of heating and cooling diffusers, arrays of generally parallel damper vanes establishing gaps therebetween mounted in said diffusers for ganged rotation together in at least some of said diffusers, servomotors each coupled to a respective one of said parallel damper vane arrays for rotating said respective arrays through a predetermined angle, linkage for coupling said respective damper vane arrays to said individual servomotors, a receiver and servomotor control individual to each of one of said servomotors for energizing said respective servomotors, respective batteries for powering said individual servomotors to rotate said respective damper vane arrays through said predetermined angle, and a wireless remote thermostat and battery controller for displaying the air temperature, switch means for said remote controller to change the air temperature to a predetermined temperature through generation of a signal that enables said receiver and servomotor controls to energize said respective servomotors to rotate at least some of said damper vanes through an angle that corresponds to said predetermined temperature, and battery recharging means for recharging respective batteries for said heating and cooling system.

6. A wireless heating and cooling system according to claim 5 wherein said wireless remote thermostat and battery control farther comprises a plug for insertion into a socket to energize said thermostat and battery control.
