DESC:An automatic ceiling fan controllable by motion, temperature and mobile/remote 5
FIELD OF INVENTION
[001] This invention relates to an automatic ceiling fan controllable by motion, temperature, and mobile/Remote. The ceiling fan constituting smart phone is operated by mobile/Remote. 10
BACKGROUND/PRIOR ART
[002] Existing ceiling fans run at fixed speed as set by user and consume fixed amount of power which lies in high range of 70~80W. 15 They are not provided with any intelligence to control the speed on its own. Currently available ceiling fans are not having any features to control the fan speed through variable temperature and motion sensor. In the absence of automation, the fan is operated manually, which renders the same inflexible. Therefore it is not user friendly. 20
[003] As a result consumption of more electricity is caused thereby adding to electricity bill.
3
[004] In view of the above it is required to introduce an automatic ceiling fan controllable by mobile/Remote which can fulfill the requirements for which the present invention has been devised.

10
[006] Another object of the present invention is to provide an automatic ceiling fan controllable by motion, temperature, and mobile/Remote which can automatically vary speed according to temperature.
15
[007] Further object of the present invention is to provide an automatic ceiling fan controllable by motion, temperature, and mobile/Remote which can sense presence and absence of human in the area of placement to automatically switch on and switch off.
20
[008] Yet another object of this invention is to propose an automatic ceiling fan controllable by motion, temperature, and mobile/Remote which is controllable through mobile and remote.

DETAIL DESCRIPTION OF THE PRESENT INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS
25
5
[0011] The present invention makes disclosure in respect of an automatic ceiling fan controllable by motion, temperature and 5 mobile/remote for automatic operation and control thereof as per requirement by user.
[0012] The ceiling fan of invention is installed with an electronic system which controls the speed of the fan through a sensor for 10 sensing the temperature of environment. This feature gives the ease to end users for automatic change in the fan speed as per variation in temperature, which can be set by the user according to his comfort.
[0013] Further the ceiling fan can be automatically switched on/off by 15 sensing through motion sensor. Ceiling fan is automatically switched OFF after certain predefined time when occupant vacates the room as well as the fan is automatically switched ON when occupant enters inside the room. This feature avoids unnecessary running of the ceiling fan which ultimately saves the power and increases life of fan. 20
[0014] A particular time period for keeping the fan switched on can also be set in the fan timer for example 2, 4, 6, 8 hours. So that the fan gets automatically switched off after the preset time. This in turn avoids the unnecessary running of fan due to ignorance/ 25 unmindfulness to switch off the fan when it is not required.
6
[0015] The fan comprises a BLDC motor with multitude of blades.
5
[0016] In addition to the above, there is provision of LED light which is dimmable. This can be employed for variation in the intensity of light in the room as well as to improve the aestheticness of the fan.
[0017] The entire operation of the fan can be carried out by means of 10 mobile or Remote for ease in operation. The remote is having the option for setting the ceiling fan control as manual or automatic.
[0018] The fan is having the provision of Wi-Fi device which is used to connect the ceiling fan with the Mobile phone of the user. The ceiling 15 fan can be connected with the Mobile phone trough Wi-Fi available in the phone. Once the ceiling fan is connected through the Mobile phone of the user, fan can be controlled with the help of a particular application downloaded in the mobile.
20
[0019] The aforesaid features render the ceiling fan a smart ceiling fan.
[0020] Reference may be made to fig. 1 illustrating sectional view of the automatic ceiling fan of invention, exploded view of which is 25 shown in figure 2. The fan comprises a down rod (1), upper end of which is connected to shackle kit (2) and lower end of which is in connection with spindle (3) of fan.
7
[0021] The down-rod is covered by means of down-rod cover (4). There is provision of a top canopy (5) covering said kit (2) and a bottom 5 canopy (6).
[0022] In addition to the above, there is provided main PCB (7) held by means of main PCB holder (8) placed over a Brushless direct current (BLDC) motor including stator (9) and rotor (10), which is 10 accommodated in a cover consisting of top cover (T1) and bottom cover (T2).
[0023] The instant invention comprises a provision of LED mounting plate (11) which is mounted on the spindle (3). A LED ring with heat 15 sink (12) is placed on said mounting plate (11). The heat sink is fitted with LED to maintain required temperature for LED.
[0024] Further, a PCB mounting bracket (13) with PCB (14) is positioned on the mounting plate (11). 20
[0025] In conjunction with the above, there is provided LED diffuser (15) with LEDs therebehind, that is placed on the PCB mounting bracket (13). Again, a fresnel plate (16) being located on a mounting bracket (13) is mounted on said LED mounting plate (11) as 25 illustrated in the figure 2. Further, there is a decorative ring (17) on said diffuser (15), which is mounted on the bracket (13).
8
[0026] Now referring to figure 3 for operation of the smart fan of the 5 proposed application. Here, the ceiling fan (A1) draws power from the power source (B1). Now the user can operate the fan through Remote (C1). The sensor such as IR sensing available in ceiling fan receives the signal from remote and operate the fan. The smart phone (D1) can be connected to the ceiling fan with the help of Wi-Fi 10 communication mode (F1) available in ceiling fan and Wi-Fi in mobile itself. After connecting the smart phone to ceiling fan, the ceiling fan can operate through mobile phone application available in smart phone.
15
[0027] The fan of invention is having a control unit housing a plurality of sensors so as to receive input through mobile/remote in the form of signal and process the same through said PCB (14) for controlling the operation of fan according to the user need.
20
[0028] The sensors include motion sensor (G1), temperature sensor (I1) and a sensor such as infrared sensor for receiving input from remote/mobile. The motion sensor (G1) in the fan senses the presence of the occupant in the room. In case, there is no occupant in the room, the fan is automatically switched off, otherwise it 25 remains operational.
9
[0029] There is also availability of clock provision (H1) to synchronize 5 mobile clock with the fan, through which the time is automatically set in the fan once the mobile phone is connected to the fan.
[0030] The temperature sensor (I1) senses the environment temperature and controls the speed of fan accordingly. 10
[0031] There is also provision of LED indicator (J1) in the fan, which gives indication to user regarding improper operation of fan by user and smooth operation of fan as well. This is visible through the fresnel plate of fan. 15
[0032] The light intensity of the dimmable LED (K1) can be varied (increased or decreased) through the remote/mobile phone.
[0033] The arrangement for the dimmable LED has already been 20 explained with reference to features (11-15) of fan in figure 2.
