DETAIL DESCRIPTION OF THE PRESENT INVENTION WITH REFERENCE TO THE ACCOMPANYING DRAWINGS
[009] The present invention teaches a technology pertaining to a ceiling fan with BLDC (Brushless direct current) motor. This fan 20 includes a LCD based digital display system having electronic control system to reflect various features/controls of the fan in the display.
5
[0010] The LCD display of fan indicates the power saving in %ge at all speed as compared to conventional induction motor ceiling fan. Also it shows the speed of the fan from 1 to 5 speeds through the bars in 5 the display, wherein each displayed bar shows each speed of the fan, i.e. 1 visible bar shows speed 1 and 5 visible bars shows speed 5 of the fan. Ceiling fan speed in numbers (numeric digit) from 1 to 5 is also displayed in digital display system. Fan speed display in numerical digit becomes inactive when timer is activated in ceiling 10 fan. For the same, reference may be made to fig. 1 indicating fan (A), Remote (B), saving of power (C), speed bars (D) and Timer (E).
[0011] Another feature of the fan is to set the fan timer at required number of hours, which is displayed by the display. Therefore ceiling 15 fan is automatically switched off when set time is over. The ceiling fan display system can be controlled through remote for ease of customer use. Remote can be employed to control the fan speed, for timer setting at different hours, fan ON/OFF as well as display system ON/OFF. Display system of the ceiling fan is placed at its 20 lower portion that makes ceiling fan more interactive and improves the aesthetic appeal thereof as well.
[0012] Now, reference may be made to fig 2. When the user controls operation of the fan by means of remote (1), it activates sensor for 25 example Infrared (IR) sensor (2) provided in the ceiling fan itself. Thereafter, electronic processor (3) in the fan processes the received signal from said sensor. The processor is installed with a software for
6
necessary processing of inputs and generates the output signal for display system (4) which displays the feature (s) selected by the user through said remote.
[0013] The above provision except the remote has been effected inside 5 the fan as illustrated in fig. 3, exploded view of which is shown in figure 4.
[0014] The fan comprises a down rod (D1), upper end of which is connected to shackle kit assembly (S1) and lower end of which is 10 provided in connection with spindle (S2) of the fan, wherein the down rod is covered by means of down-rod cover (D2). The down-rod cover is in contact with top canopy (T1) at the top end thereof and bottom canopy (T2) at the bottom end thereof.
15
[0015] The top canopy (T1) covers said shackle kit (S1) and the bottom canopy (T2) provides coverage to main PCB housing accommodating main PCB (M1). The main PCB housing comprises of top PCB housing (H1) and bottom PCB housing (H2). The main PCB housing is mounted on the housing of Brushless direct current (BLDC) motor of 20 fan.
[0016] The motor (stator and rotor) (M) is housed in a cover having top cover (C1) and bottom cover (C2). The bottom cover is provided with display mounting plate (P) for mounting display unit (N), covered with 25 the help of display cover (V), in which PCB for display is positioned behind said display unit (N) forming part of display system.
7
[0017] The sensor (2) is placed on the back side of the display cover 5 (V).
[0018] The display cover is preferably a transparent cover so as to render the display visible to the user.
10
[0019] The display cover (V) is located at the center of a display cover ring (R). The display cover ring conceals the transparent display cover with display and PCB thereof. Both the PCBs of said motor and display are in communication with each other.
15
[0020] A bracket (Not shown) for display is mounted on the spindle of the fan, in which display cover with display and PCB thereof constituting a single unit is placed on the bracket.
[0021] The display is automatically switched on with the fan and auto 20 switched off after a certain time period to save power. However, the display can be switched on at any point of time during operation of fan. Further, said display can be switched off any time with remote without affecting fan operation to avoid disturbance to user particularly at night while sleeping. 25

[0022] As the fan requires less power for operation thereof in comparison to induction motor fan, therefore the same gets less 5 heated. This in turn needs less energy to be consumed by air condition so as to cool down the room.
[0023] Now, reference may be made to fig. 5 reflecting the display during actual operation of ceiling fan, wherein the ceiling fan is set at 10 maximum speed of 5 for 8 hours, which is saving 55% power as compared to currently available induction motor ceiling fan. Here as the timer is active therefore numerical value of the speed in invisible. However, the same can be known by counting the bars appearing on the display as shown in the figure. Power saving in %ge always 15 appears in the display.
[0024] Thus the Present invention displays power saving details, speed and fan setting details to end users which renders the fan very interactive and useful for the users. 20
[0025] Further, through remote the electronic system of display system can control various features of fan including power saving, timer setting, fan speed, fan ON/OFF as well as display ON/OFF.
