An operation system for a home electric appliance (12) has a mobile terminal (16) to send an operation signal for operating the home electric appliance (12), and a communication device (14) to send the operation signal from the mobile terminal (16) to the home electric appliance (12). The mobile terminal (16) sends, by way of a user operation, to the communication device (14), a request signal for requesting the communication device (14) to send, to the mobile terminal (16), information on the working status of the home electric appliance (12) after receiving the operation signal. Upon receiving the request signal from the mobile terminal (16), the communication device sends, to the mobile terminal (16), information on the working status of the home electric appliance (12) after receiving the operation signal. The mobile terminal (16) notifies the user of the information on the working status of the home electric appliance (12) after receiving the operation signal sent from the communication device (14). The mobile terminal (16) notifies the user that the operation signal has been sent to the home electric appliance (12) and at the same time prompts the user to perform operations to send the request signal.
