Description
- Not applicable to this application.
- Not applicable to this application.
- 1. Field of the Invention
- The present invention relates generally to heating and cooling vents and more specifically it relates to a thermostat controlled vent system for automatically controlling airflow through a HVAC vent.
- 2. Description of the Related Art
- Heating, ventilation and air conditioning (HVAC) vents have been in use for years. A conventional HVAC vent is comprised of a frame structure, a plurality of fin members for directing the airflow and a manually operated valve member. Each conventional HVAC vent is connected to an air duct that is connected to a central furnace and/or air conditioner.
- The main problem with conventional HVAC systems is that they do not adequately heat or cool specific rooms/areas of a building structure. Another problem with conventional HVAC systems is that they do not allow a user to control the temperature within an individual room/area since the control of the HVAC systems occur at a central location within the building structure.
- Various products have been created for assisting in controlling the airflow through HVAC vents such as air deflectors, airflow boosters, in-line duct fans, and magnetic vent covers. In addition, zone control units that control airflow through the main ducts have been utilized to control the airflow through main air ducts thereby effectively controlling large zones within a building structure. However, none of these prior art products provide an efficient system for controlling the airflow through a plurality of individual HVAC vents.
- Examples of patented devices which may be related to the present invention include U.S. Pat. No. 5,833,134 to Ho et al.; U.S. Pat. No. 2002/0,058,473 to Park; U.S. Pat. No. 6,340,329 to Park; U.S. Pat. No. 4,722,266 to Deckert; U.S. Pat. No. 6,261,174 to Kuehn; U.S. Pat. No. 4,163,144 to Reynier; U.S. Pat. No. 4,646,964 to Parker et al.; U.S. Pat. No. 4,699,045 to Hensley; U.S. Pat. No. 5,364,304 to Hampton; U.S. Pat. No. 5,489,238 to Asselbergs; U.S. Pat. No. 5,632,677 to Elkins; U.S. Pat. No. 5,149,299 to Sauer; U.S. Pat. No. 4,846,399 to Asselbergs; and U.S. Pat. No. 4,809,593 to Asselbergs.

The central control unit will optimize heating, air conditioning, air-flow and energy use based on multiple criteria such as local temperature, user settings, season, time of day and use patterns for the space. In an alternative embodiment, the vent unit may have a thermostat unit positioned within the frame structure of the vent unit for controlling the drive motor. The unit may be powered by a replaceable battery, a rechargeable battery with power source or by an external power source connected directly via wires.

It can be appreciated that various other data entry systems may be utilized to enter data into thecentral control unit 20 other than illustrated in FIG. 3 of the drawings. - As shown in FIG. 2 of the drawings, the
remote control unit 30 has aremote interface 32 which displays the relevant information relating to the operation of thespecific vent unit 40 it is in communication with. Theremote control unit 30 may control more than onevent unit 40 such as by controlling a group ofvent units 40. Theremote interface 32 preferably is a digital display that allows for the entry of data and the selection of functions directly within theremote interface 32. It can be appreciated that various other data entry systems may be utilized to enter data into theremote control unit 30 other than illustrated in FIG. 2 of the drawings. It is desirable to have override functionality within theremote control unit 30 if thevent unit 40 is also in communication with acentral control unit 20. - FIGS. 6 and 7 illustrate alternative embodiments of the present invention by using a thermostat unit47 (similar to the remote control unit 30) or a
mechanical thermostat 49. This alternative embodiment simplifies the present invention. As shown in FIG. 8 of the drawings, it is desirable to utilize a deflector member near thefin members 45 to prevent the airflow from directly engaging the thermostat when thethermostat unit 47 or themechanical thermostat 49 are utilized. - As shown in FIG. 9 of the drawings, an
HVAC damper unit 50 may also be in communication with thecentral control unit 20 to allow for the control of airflow into various zones of a building structure. TheHVAC damper unit 50 may be utilized in conjunction with thevent units 40 as desired. - Various other electronic devices may be in communication with the
vent unit 40 or thecentral control unit 20 or theremote control unit 30 to provide automated operation of the present invention. For example, motion sensors may be in communication to indicate when a person is within the room so that thevent unit 40 may respond accordingly. Another example is the usage of light sensors in communication to indicate daylight hours or to indicate that an individual has turned the lights on within the room. Various other devices may be utilized to communicate various types of data to the present invention which may be utilized to react accordingly. - In use, the user programs the
central control unit 20, theremote control unit 30, thethermostat unit 47 or themechanical thermostat 49 as desired. Thevent unit 40 thereafter controls the airflow through thevent unit 40 based upon the room temperature and the programmed settings. If the temperature within the room is too cold and the HVAC is produceing heated air, thedrive motor 44 is operated to open thebaffle member 41. If the temperature within the room is too hot and the HVAC is producing heated air, thedrive motor 44 is operated to close thebaffle member 41. If the temperature within a room is too hot and the HVAC is producing cooled air, thedrive motor 44 is operated to open thebaffle member 41. If the temperature within the room is too cold and the HVAC is producing cooled air, thedrive motor 44 is operated to close thebaffle member 41. The operation of thedrive motor 44 and thebaffle member 41 is determined by the range of temperature requirements preset by the user. Thecentral control unit 20 is a smart system that learns over time and directs the activities of the vents and the HVAC to provide heating and cooling to the rooms that demand it. - As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
- With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed to be within the expertise of those skilled in the art, and all equivalent structural variations and relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
- Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
