Distant remote-control device of electric appliance

DETAILED DESCRIPTION The primary object of the present invention is to propose a distant remote-control device of electric appliance utilizing the characteristic of infrared remote-control signals capable of learning mutually to directly learn remote-control signals of electric appliances, thereby achieving remote control of electric appliances using a telephone without attaching electric wires on electric appliances or modifying internal circuits thereof.
Another object of the present invention is to propose a distant remote-control device of electric appliance with an inbuilt code-discriminating device to provide discrimination of code for a user, hence securing safety of use of the distant remote-control device.
Yet another object of the present invention is to propose a distant remote-control device of electric appliance of simple operation and convenient use.
To achieve the above objects, the present invention comprises a telephone remote-control mainframe, and a signal converter.
The telephone remote-control mainframe is connected with a telephone line to provide distant remote control for a user using telephone tones.
The signal converter first learns and stores infrared remote-control signals of an electric appliance such as an air-conditioner/heater, and correspondingly obtains a digital address serial code.
On the other hand, a switch of a wireless remote-control gas oven is controlled using a special controller, which also has a corresponding address serial code.
The telephone remote-control mainframe emits different control signals to individually maneuver the signal converter and the special controller, thereby letting the signal converter convert the control signals into corresponding infrared remote-control signals to control the action of the air-conditioner/heater and letting the special controller directly receive the control signals to control the switch of the gas oven.
Next, the air-conditioner/heater emits a sensing signal to the telephone remote-control mainframe via a sensing-signal emitter, and the special controller also emits an acknowledge signal to the telephone remote-control mainframe to inform the user that the instructions have been finished
