In this case, when it is determined that the object is detected in the object detecting step (S06), by sending a control signal for the object detection notification to the speaker signal processing module 551 to send a notification signal from the speaker 55. Notification sound sending step (S07) is performed.

And if the object is still detected after the notification sound transmission step (S07) by transmitting a control signal from the main control unit 50 to the lamp power unit 231, the near infrared ray to cut off the lamp power supplied to the near infrared lamp 22 Perform a lamp operation stop step (S08) to temporarily stop the heater operation, and if the object is still detected after the near-infrared lamp operation stop step (S08) to cut off the power supply from the power supply 111 to operate the system. The system termination step (S09) for terminating is to be performed.

In the near-infrared heater (A) according to the present invention in particular in the notification Sophie sending step (S07), when the object is detected for the first time only the data value for the object is detected in the memory unit (not shown), and then If an object is continuously detected after a predetermined time interval (for example, about 4 seconds to about 10 times), the interval sound may be generated as the initial emergency sound from the main controller 53 to the speaker 55. If the object is continuously detected afterwards, the continuous sound may be controlled. If the object is still detected afterwards, the near-infrared lamp operation stop step (S08) and the system termination step (S09) are performed, so that even if the object is located in front of the near-infrared lamp 22, a fire does not occur and can be used safely. There is an advantage that can be prepared.

As described above, although described with reference to a preferred embodiment of the present invention, those skilled in the art without departing from the spirit and scope of the invention described in the claims below In the present invention can be carried out by various modifications or variations.
