Abstract

A method and device for detecting a foreign matter for a wireless power transmission system, a household appliance and an air conditioning system are provided. The wireless power transmission system includes a transmitting end and a receiving end. The receiving end includes a receiving detection coil and a receiving work coil, and a mutual inductance corresponding to the receiving detection coil is greater than a mutual inductance corresponding to the receiving work coil. The method includes: controlling the transmitting detection coil of the transmitting end to send an electric energy to the receiving end and obtaining a transmitting power of the transmitting end; obtaining a receiving power when the receiving end receives the electric energy transmitted by the transmitting end; obtaining a result of a foreign matter detection based on the transmitting power and the receiving power.
