, Description:FIELD OF THE INVENTION

The present invention generally relates to an automatic and smart and intelligence fan. The invention particularly relates to fan having automatic on/off control, speed variation control, direction changing control and expandable/collapsing modes.

BACKGROUND OF THE INVENTION

Now a days ceiling fans are looked at as a necessary product in home interiors. The reason for this is most likely geographical placement. Where ceiling fans are a much more important and natural part of the home interiors. It could also be a consequence of tradition, many people aren’t used to the product and do not see an obvious need for one. Another possibility could be that there actually aren’t any ceiling fans on the market that satisfies middle class people’s desires, needs and demands for their environments and homes. Current ceiling fans are working as semi-automatic without user friendly nature.
Problems have developed as to the operations of the fans. For example, traditional fans are often left on when occupants leave rooms with overhead ceiling fans. Thus, the fans can consume unnecessary power in unoccupied rooms. Another problem occurs when newly arriving occupants to new rooms and/or to darkened rooms have to search for hard to find wall toggle switches and/or overhanging chains to turn on the ceiling fans. Warm and/or stuffy rooms can be very uncomfortable to newly arriving occupants, who would have to wait for the rooms to cool down and circulate airflow. Further, turning on and off several fans in a home or building is often so inconvenient that fans are left on.
A number of different type of the tools and methods for replacing/changing ceiling fan are available in the prior art. For example, the following patents are provided for their supportive teachings and are all incorporated by reference:
Prior art document,US5996898A discloses a ceiling fan operation control for turning the fan on and off based on a passive infrared sensor, combined with a temperature sensor to regulate the speed of the fan. The passive infrared sensor, the temperature sensor and controls for both are in a housing directly mounted to the fan motor of the ceiling fan. The controls can be set screws covered by a removable cap. The passive infrared sensor can include a Fresnel lens for sensing a 360 degree circumference beneath the fan, and a photo-optical sensor such as a photocell, which suspends ceiling fan control changes for allowing the fan to continue operation when the room is dark and occupants may be sleeping. The reference does not appear to disclose the direction changing control.

Another prior art document, CN205101251U discloses a ceiling fan with automatic contraction work ability, including fan head, three flabellum and speed regulators that have flexible function, three the flabellum is fixed the edge all-around of fan head, the fan head is fixed on the platform sling through the jib, the fan head is connected with the speed regulator electricity, the ceiling fan is the drive arrangement control circuit of the single chip in arranging a head in, the temperature measuring device who is used for measuring ambient temperature, the drive arrangement who controls three flabellum shrinks and the work of control drive arrangement still, the single chip links to each other with temperature measuring device, drive control circuit respectively, the drive control circuit with the drive arrangement electricity is connected. The flabellum can be according to automatic shrink of ambient temperature or extension. However, this prior art document does not appear to discuss expandable/collapsing mode according to the occupancy of people.
Yet another prior art document, US20100291858A1 discloses a fan includes a hub; several fan blades, and a motor that is operable to drive the hub. A motor controller is in communication with the motor, and is configured to select the rate of rotation at which the motor drives the hub. The fan is installed in a place having a floor and a ceiling. An upper temperature sensor is positioned near the ceiling. A lower temperature sensor is positioned near the floor. The temperature sensors communicate with the motor controller, which includes a processor configured to compare substantially contemporaneous temperature readings from the upper and lower temperature sensors. The motor controller is thus configured to automatically control the fan motor to minimize the differences between substantially contemporaneous temperature readings from the upper and lower temperature sensors. The fan system may thus substantially de-stratify air in an environment, to provide a substantially uniform temperature distribution within the environment. However, this prior art document does not appear to discuss about the speed variation control of the system.
Yet another prior art document, US20090162197A1 discloses a fan system includes a fan and a fan rotation speed control. The speed control is operable to command the fan to rotate at a speed selected from a certain range of rotation speeds. A fan oscillation detector may be coupled with the fan to detect oscillation of the fan as the speed control is operated to rotate the fan at various speeds among the range of fan rotation speeds. A programmer device identifies fan rotation speeds at which the oscillation amount exceeds the threshold or is otherwise unacceptable, and programs the fan rotation speed control to prevent an operator from being able to select those speeds at which the oscillation amount exceeds the threshold or is otherwise unacceptable. However, this prior art document does not appear to discuss about the process of identifying people or object and providing the higher amount of air in that area.
Yet another prior art document, US5528229A discloses an apparatus and method for thermostatically controlling the operation of a multiple speed fan and light assembly by inputting a desired temperature range and airflow direction for each fan speed and by inputting a single number for controlling the on time and duration of the light assembly. A temperature sensor determines an initial room temperature, an input device enters a temperature set-point corresponding to each of the fan speeds, a processor stores the temperature set-points corresponding to each of the fan speeds from the input device, receives the temperature signal and uses the temperature signal and the temperature set-points to determine a desired fan speed, and a fan driving device changes the initial rotation speed to the desired fan speed in response to the processor and thereby automatically controls the fan speed. The reference does not appear to disclose the automatic enlarging or shrinking of the blades according to the occupancy of people.
Yet another prior art document, US6211632B1 discloses a direction control device for a ceiling fan, which has a remote receiver arranged inside a canopy of the ceiling fan and a direction control circuit unit arranged in a switch box of the ceiling fan. The conducting wires of the remote receiver and the connection lines of the fan motor are both electrically connected to the direction control circuit unit via a hanger rod of the ceiling fan without being redirected and the rotation direction of the ceiling fan can be remotely controlled. However, this prior art document does not appear to discuss the speed variation control.
However, above mentioned references and many other similar references has one or more of the following shortcomings: (a) On off control is absent; (b) Speed variation control is unavailable; (c) Does not have direction changing control; (d) Expandable/collapsible modes are absent; (e) Noisy; (f) Complex; (g) Expensive; and (h) Burning smell.
The present application addresses the above mentioned concerns and shortcomings with regard to providing an intelligence smart interactive fan.

Smart thermostats, Smart light bulbs sure you’ve heard of these innovative products before. But smart ceiling fans? Yes, even fans are becoming smart and contribute to your home’s overall climate control. Though ceiling fans obviously offer limited cooling relief, they can do so at a much cheaper price point. A central air conditioning system consumes 3 kilo Watts, which is about 36 cents per hour, while running a fan only runs at 30 Watts, equivalent to only a cent per hour. Now, one don’t have to choose between the two. Using an air conditioner and fan in tandem beats the heat better and can keep your energy costs down. It’s recommended that you run your AC and ceiling fan at the same time. To do this efficiently, you’ll need the help of smart ceiling fans. Think of it as your regular ceiling fan that knows when to spin itself. Like smart thermostats, they can be remotely controlled and can be programmed to switch on depending on the preset temperatures and schedules. They can even be linked to your smart thermostats like Nest or Ecobee. Smart ceiling fans may sound like a splurge purchase, but they actually help with your home’s indoor climate control and keep your electricity bill down. Running a ceiling fan on cue helps circulate the cool air in a room, enabling you to operate your AC several degrees higher without experiencing discomfort. And for every degree raised, you are saving the “on” cycles of your AC compressor by 10%, reducing your total energy consumption. The present invention is one of the novel and improved smart fan more smarter than available in the market. The smart fan of the present invention has many features which are not available in the fan of the prior art.
