Abstract
A control system is described for controlling an appliance, such as a fan. The control system includes a user-operable remote control for transmitting light signals, a control circuit for controlling at least one component of the appliance, such as a motor, and a user interface circuit for supplying control signals to the control circuit. The user interface circuit includes a switch and a receiver for receiving light signals transmitted by the remote control. A push button actuator both actuates the switch through movement of the actuator towards the switch, and conveys light signals received from the remote control to the receiver.
Claims16
A control system for controlling an appliance, the control system comprising:
- a remote control for transmitting light signals;
- a control circuit for controlling at least one component of the appliance;
- a user interface circuit for supplying control signals to the control circuit, the user interface circuit comprising a switch, a receiver for receiving light signals transmitted by the remote control, and a light emitting device;
- and
- an actuator for actuating the switch through movement of the actuator towards the switch, the actuator configured to convey light signals received from the remote control to the receiver, and to convey light emitted by the light emitting device to an external surface of the actuator.
A fan comprising an air inlet, an air outlet, an impeller, a motor for rotating the impeller to draw air through the air inlet, and a control system for controlling the motor, the control system comprising:
- a remote control for transmitting light signals;
- a control circuit;
- a user interface circuit for supplying control signals to the control circuit, the user interface circuit comprising a switch, a receiver for receiving light signals transmitted by the remote control, and a light emitting device;
- and
- an actuator for actuating the switch through movement of the actuator towards the switch, the actuator configured to convey light signals received from the remote control to the receiver, and to convey light emitted by the light emitting device to an external surface of the actuator.
