Electrical instrument

1. An electrical instrument comprising:

a main function section that is controlled by a main function section control unit and executes a main function that is a function as a main object of the electrical instrument;

a communication section that receives an aspect of the main function to be executed by the main function section from an external information terminal by near field communication, the communication section being provided separately from the main function section, the aspect being an aspect in which the electrical instrument exerts a function as a main object of the electrical instrument;

an input section for allowing a user to input an aspect of the main function to be executed by the main function section;

a notification section for issuing a notice on information regarding the near field communication, the information containing abnormality of the communication section; and

a control unit provided separately from the main function section and the communication section, wherein

the control unit includes:

the main function section control unit that controls the main function section based on the aspect of the main function, which is inputted to the input section, and based on the aspect of the main function, which is received by the communication section;

an abnormality sensing unit that senses the abnormality of the communication section;

a history recording unit that records a near field communication control history that is a history that the main function section control unit has controlled the main function section based on the aspect of the main function, which is received by the communication section; and

a notification content decision unit that decides to issue a notice on the abnormality of the communication unit in the case where the abnormality sensing unit senses the abnormality and the near field communication control history is recorded in the history recording unit and that decides not to issue the notice on the abnormality of the communication unit in the case where the abnormality sensing unit senses the abnormality and the near field communication control history is not recorded in the history recording unit.

2. The electrical instrument according to claim 1 ,

wherein the history recording unit is further configured to record an input control history that is a history that the main function section control unit has controlled the main function section based on the aspect of the main function, which is inputted to the input section,

the electrical instrument further comprises;

a history analysis unit that, based on the near field communication control history and the input control history, which are recorded in the history recording unit, analyzes a relative frequency (hereinafter, referred to as a near field communication control relative frequency) of a fact that the main function section control unit has controlled the main function section based on the aspect of the main function, which is received by the communication section, to a fact that the main function section control unit has controlled the main function section based on the aspect of the main function, which is inputted to the input section, and

the notification content decision unit is configured to decide to issue a notice on information that prompts implementation of the communication between the electrical instrument and the information terminal as the information regarding the near field communication in the case where the near field communication control history is recorded in the history recording unit and the near field communication control relative frequency is lower than a predetermined value.

3. The electrical instrument according to claim 1 ,

wherein the electrical instrument is a home electrical instrument,

the electrical instrument further comprises:

an operation sensing section that senses an operation result of the main function section; and

a working condition analysis unit that determines whether or not the home electrical instrument is used in a user's life based on the operation result sensed by the operation sensing section, and

the history recording unit starts to record the near field communication control history in the case where the working condition analysis unit determines that the home electrical instrument is used in the user's life.

4. The electrical instrument according to claim 3 ,

wherein the electrical instrument is a home heating cooking device,

the main function section at least includes a heating chamber and a heating section that heats food housed in the heating chamber,

the operation sensing section is a temperature sensing section that senses a temperature of the heating chamber, and

the working condition analysis unit determines that the heating cooking device is used in the user's life in the case where the main function section control unit performs control to operate the heating section and the temperature sensing section senses a change of a temperature of the heating chamber.

5. The electrical instrument according to claim 3 ,

wherein the electrical instrument is a home washing and drying machine,

the main function section includes a washing machine tub, a motor that rotates the washing machine tub, and a feed valve that feeds the washing machine tube with water by open and close of the feed valve,

the operation sensing section is a water sensing section that senses whether or not water is present in the washing machine tub, and

the working condition analysis unit determines that the home washing and drying machine is used in the user's life in the case where the main operation control unit performs control to rotate the motor after the main operation control unit performs control to open the feed valve and the water sensing section senses that water is present in the washing machine tub.

6. The electrical instrument according to claim 1 , wherein the electrical instrument is a microwave oven, a rice cooker, a television set, an air conditioner, a washing machine, or a refrigerator.
