に電力が消費されている。2. Description of the Related Art At present, almost all air conditioners are operated by a remote controller to start and stop operation and to switch operation modes. The indoor unit of the air conditioner includes, for example, a light receiving unit that receives signal light such as infrared light, and a microcomputer that generates a code signal for reception based on the content of the received light, and displays an operation state. A lamp and the like are provided to constitute a remote control circuit. These remote control circuits are always supplied with power from a commercial power supply via a main power switch and kept in a standby state in order to wait for a signal from a remote control transmitter even in an operation stop state. For this reason, although a small amount (about 2 W), power is always consumed.

いることが多く、省エネの観点から問題となっている。[0003] In recent years, there has been an increasing interest in power saving of household appliances due to the problem of CO2 emission. To eliminate the standby power of the air conditioner, it is necessary to turn off the main power switch of the indoor unit or disconnect the power cord. However, most of the indoor units are installed on the upper wall of the room, and it is not easy for the user to turn off the main power switch or disconnect the power cord. In particular, standby power is often consumed even during the off-season when the air conditioner is not used for a long period of time, which is a problem from the viewpoint of energy saving.
