Appliance control apparatus and electrical appliance
First Claim
1. An appliance control apparatus comprising:
- an antenna for receiving radio waves;
a power receiving unit for taking out power from the radio waves received by said antenna;
a capacitor for accumulating the power taken out by said power receiving unit;
a signal receiving unit operated with the power accumulated in said capacitor and receiving a signal from the radio waves received by said antenna;
an ID signal holding for holding a signal indicative of an appliance ID;
a switch for selectively connecting an appliance and a power source; and
an ID signal comparing unit for receiving the signal from said signal receiving unit, comparing a target appliance ID contained in the received signal with the appliance ID read out from said ID signal holding unit when the received signal is a predetermined signal, and turning on said switch when both the ID'"'"'s are matched with each other.

Abstract
Power is taken out from radio waves through an antenna and a power receiving unit. A signal receiver, a comparator, and an ID signal holder are operated with the taken-out power to compare an ID contained in a received signal with an ID read out from the ID signal holder. When both the ID'"'"'s are matched with each other, a switch for a main power source is turned on. In trying to remotely operate household electrical appliances by utilizing the Internet that has become increasingly popular, standby power is consumed if the electrical appliances are kept in a standby state at all times. Since power is taken out from radio waves, the invention is able to cut the standby power in an environment where the radio waves are transferred via radio communication that is expected to be more and more prevalent in future.

6. An appliance control apparatus comprising:
-
an antenna for transmitting and receiving radio waves;
an ID signal transmitting unit for transmitting, to an appliance, power and a signal containing an ID of said appliance via said antenna; and
a communication control unit for starting communication when said communication control unit receives, from an appliance designated by the appliance ID contained in the signal transmitted from said ID signal transmitting unit, a signal indicating that the designated appliance is in a state ready for reception. - View Dependent Claims (7, 8)
