For example, there is a fan provided with a remote control. The switch on the fan is operated by a radio controlled receiver, and a hand held transmitter is adapted to permit a user to select multiple fan speeds and direction of blade rotation.
- However, both of the above designs are controlled by a single device (e.g., control). Thus, the fan is useless if the control is malfunctioned.
- Further, a fan can be controlled in a duo mode (i.e., controlled remotely or by a conducting wire) has not been disclosed as far as the inventor is aware. Thus, the invention described below is neither taught nor rendered obvious.

As a result, themotor 31 rotates or stops rotating in response to the instruction. Themicroprocessor 45 further generates a feedback signal which is sent back to thewire control module 46. Thewire control module 46 further processes the signal to generate a signal representing information in digital form. As a result, the user can see a corresponding representation of information for confirmation shown on thedisplay 323. The user may operate thebuttons 321 to set standby or sleep of themotor 31. - In addition to above operating mode, the user may alternatively use a wireless operating mode. In detail, the user may press the
button 331 to select speed and even start or stop themotor 31. In response, an RF signal is transmitted from theremote control 33 to theremote control module 47. Theremote control module 47 sends the signal to thecontrol 32. And in turn, thecontrol 32 sends the signal to thewire control module 46 which in turn sends the signal to themicroprocessor 45 for processing. And in turn, themicroprocessor 45 creates a signal and sends the signal to thecontrol IC 44 which in turn processes the signal to send an instruction to themotor controller 43. As a result, themotor 31 rotates or stops rotating in response to the instruction. Themicroprocessor 45 further generates a feedback signal which is sent back to thewire control module 46. Thewire control module 46 further processes the signal to generate a signal representing information in digital form. As a result, the user can see a corresponding representation of information for confirmation shown on thedisplay 323. The user may operate thebuttons 331 to set standby or sleep of themotor 31. - It is envisaged by the invention that a user can operate a fan in either a remote control mode or a mode of control by a conducting wire. Thus, an additional operation mode is provided to a user for selection.
- Although the invention has been described in detail, it is to be understood that this is done by way of illustration only and is not to be taken by way of limitation. The scope of the invention is to be limited only by the appended claims.
Claims (1)
1. A mechanical fan comprising:
a brushless DC motor;
a controller assembly mounted in the brushless DC motor and electrically connected to the motor;
a control electrically connected to the controller assembly; and
a remote control;
wherein the controller assembly comprises a filter, a full-wave rectifier electrically connected to the filter for converting AC into DC, a motor controller electrically interconnected the full-wave rectifier and the brushless DC motor, a wire control module electrically connected the control, a microprocessor electrically connected to the wire control module, a control IC electrically interconnected the motor controller and the microprocessor, and a remote control module electrically connected to the control; and
wherein in response to an operation of either (i) the control a first signal is generated, the first signal is sent to the wire control module which in turn sends the first signal to the microprocessor for processing, or (ii) the remote control an RF signal is transmitted from the remote control to the remote control module, the remote control module sends the RF signal to the control which in turn sends the RF signal to the wire control module, the wire control module sends the RF signal to the microprocessor for processing so that the microprocessor creates a second signal and sends the second signal to the control IC which in turn processes the second signal to send an instruction to the motor controller, and the motor controller activates or deactivates the brushless DC motor.
