A heat shielding cover 3 is mounted on the base 2, and a handle 4 is provided on the heat shielding cover 3.

The handle 4 is provided with a grip switch 5 as a usage state detection means that is turned on when the handle 4 is gripped. This grip switch 5 is configured such that a grip portion 6 serves as an actuator to open and close contacts 7. Furthermore, the grip switch 5 has an oscillation circuit (not shown) and is connected to a transmitting device 8 as a usage status information transmitting means attached to the tip of the handle 4. When the grip switch 5 is turned on, the The transmitting device 8 transmits a signal A such as an infrared signal almost all around the circumference. 9 is an ironing board, top play 1~
A cloth 11 is provided on the upper surface of the top plate 10, and a heating coil 12 as an electromagnetic induction heating device is provided on the lower surface side of the top plate 10. A control circuit 13 that processes the received signal and also controls the temperature 11111, etc.
The heating coil 12 is connected via a driving circuit 14 to a receiving device 15 as a usage state information receiving means provided protruding from the side of the ironing board 9.

Next, the operation of the structure of the above embodiment will be explained.

Place an item to be ironed (not shown) such as clothes on the ironing board 9 in advance, place the iron body 1 on top of it, and when you grip the handle 4, the switch 5 to be gripped turns ON, and in response, a signal is sent from the transmitting device 8. A is sent. When the receiving device 15 receives this signal A, the control circuit 13 and the drive circuit 1
4 supplies power to the heating coil 12 to generate magnetic lines of force B, and as a result, the base 2 located within the lines of magnetic force B is heated by hysteresis loss or Joule heat and can be ironed. Also, the handle 4 is not gripped,
That is, when the iron main body 1 is placed on the ironing board 9 with the grip switch 5 not ON, the signal A is not transmitted, and as a result, the heating coil 12 is not supplied with power, and the base 2
is not heated by induction. Further, even if a spoon (not shown) or the like is placed on the ironing board 9 instead of the iron main body 1, the signal A is not transmitted, and the spoon or the like will not be heated by induction to a high temperature.

As described above, in the embodiment, the induction heating type cordless iron which heats the metal base 2 by induction by providing the heating coil 12 for induction heating on the ironing board 9,
