Abstract

Provided is an electrical appliance which can stably communicate with a reader / writer and can prevent damage and separation, etc. of a wireless IC element. A wireless IC element (30) for processing high frequency signals is disposed inside an electrical appliance main body (2), and an input / output terminal of the wireless IC element (30) is joined to at least part of a power source cable (15) leading outside from the electrical appliance main body (2).

Description

technical field [0001] The present invention relates to electrical products, in particular to electrical products that can make good use of wireless communications such as RFID (Radio Frequency Identification: radio frequency identification) systems. Background technique [0002] Conventionally, as an item management system, an RFID system has been developed in which a reader / writer generating an electromagnetic field communicates with an RFID tag (wireless IC device) attached to an item and stores predetermined information in a non-contact manner to transmit information. Patent Documents 1 and 2 show examples in which RFID tags are used for collection management of home electric appliances. However, in the recycling system described in Patent Document 1, since the tag is mounted on the control board built in the door of the refrigerator, if a metal material is placed around the tag, it may obstruct the communication with the reader / writer. stable communication. Patent Doc...
