Home network power saving device and method for the same
First Claim
1. A home network system with a standby power saving function, comprising:
- at least one home appliance including a controller for analyzing data received over a network line and generating and outputting a home appliance control signal in accordance with the analyzed result, a low voltage transformer (LVT) for supplying a drive voltage to said controller, and power control means for controlling the supply of the drive voltage from said LVT to said controller according to whether said home appliance is in operation; and
a home server for transmitting and receiving data to/from said home appliance over said network line,wherein said power control means includes;
an LVT relay turned on/off for supplying or blocking an external voltage from a main power line to said LVT according to whether said home appliance is in operation, said LVT relay being disposed directly between the main power line and the LVT; and
power supply means connected between said LVT and said controller for supplying said drive voltage from said LVT or a charged voltage to said controller, said power supply means being disposed directly between the LVT and the controller.

Abstract
A home network system with a standby power saving function and a method for saving standby power thereof, wherein various home appliances exchange information with a home server from time to time. At least one home appliance for a home network is provided in the home network system to exchange information with the home server over a network line. The home appliance includes a controller for analyzing data received over the network line and generating and outputting a home appliance control signal in accordance with the analyzed result, a load for operating/stopping the home appliance in response to the home appliance control signal from the controller, a low voltage transformer (LVT) for receiving an external voltage and supplying a drive voltage to the controller to operate the load and controller, and an LVT relay and a power supply unit for cooperating to selectively supply the drive voltage and a standby voltage to the controller according to whether the home appliance is in operation. When the home appliance is in a standby mode, the supply of external power is interrupted and only the minimum power necessary for the controller is supplied, thereby making it possible to save the same amount of standby power as that of LVT leakage power.

7. A method for controlling power of a home network system, said method comprising:
-
analyzing, via a controller included in a home appliance, data received over a network line from a home server to determine if the home appliance is to be in an operation mode or a standby mode; supplying, via a low voltage transformer (LVT), a drive voltage to said controller based on whether the controller determines the home appliance is to be in the operation mode or in the standby mode; and controlling, via a power control device, the supplying of the drive voltage from said LVT to said controller according to whether the controller determines said home appliance is to be in the operation mode or in the standby mode, wherein said controlling step further includes; turning on and off an LVT relay to supply or block an external voltage from a main power line to the LVT according to whether the controller determines said home appliance is to be in the operation mode or in the standby mode, said LVT relay being disposed directly between the main power line and the LVT; and supplying, via a power supply device connected between said LVT and said controller, said drive voltage from said LVT to the controller or supplying a charged voltage to the controller according to whether the controller determines said home appliance is to be in the operation mode or in the standby mode, said power supply device being disposed directly between the LVT and the controller. - View Dependent Claims (8, 9, 10, 11, 12)

13. A home network system with a standby power saving function, comprising:
-
at least one home appliance; and a home server connected to said at least one home appliance over a network line and configured to transmit and receive data to and from said home appliance, wherein the at least one home appliance includes; a controller configured to analyze data received over the network line and to output a home appliance control signal in accordance with the analyzed result; a low voltage transformer configured to supply a drive voltage to the controller; an LVT relay configured to be turned on and off to thereby supply or block an external voltage from a main power line to said LVT according to whether said home appliance is in operation, said LVT relay being disposed directly between the main power line and the LVT; a power supply circuit connected between said LVT and said controller and configured to supply said drive voltage from said LVT or a charged voltage to said controller, said power supply means being disposed directly between the LVT and the controller. - View Dependent Claims (14, 15, 16, 17, 18)
