Abstract

PROBLEM TO BE SOLVED: To reduce power consumption at standby in an air conditioner with a remote controller.SOLUTION: This air conditioner is an electronic apparatus having a signal receiving part which receives a carrier signal transmitted from the remote controller, an operation processing part which operation-processes the carrier signal, and a circumferential circuit which is connected to the operation processing part and controlled. A power supply circuit for driving the signal receiving part, the operation processing part and the circumferential circuit is divided into a first power supply circuit which supplies power to a specified load including the operation processing part, and a second power supply circuit which supplies power to the circumferential circuit.

Description

technical field [0001] The present invention relates to electronic equipment provided with a power saving mode during standby. Background technique [0002] TVs, audio equipment, air conditioners, etc. These products are generally used in places far away from users. Therefore, use another remote controller (remote controller) to perform remote operations, to perform power on and off or switch various functions. , Action switching. In particular, the indoor unit of an air conditioner is often installed at a high place indoors, so almost all operations are performed by a remote controller. [0003] In these devices operated by the remote controller, the operation from the stopped state to the running state is also performed by the remote controller. Therefore, even in the stopped state, signal reception including a carrier signal for receiving information with an operation command is carried out. The control circuit and the power supply circuit of the microcomputer (microcom...
