When the first and second plate flow sensing switches 779a and 779b are turned on, the first heating wire control unit 701 senses this and the first heating wire control unit 701 turns off the current control switch 750 The current supplied from the first heating line control unit 701 can be prevented from being supplied to the second longitudinal heating line 732. When the first and second plate flow sensing switches 779a and 779b are turned off, The first heating wire control unit 701 senses this and the first heating wire control unit 701 turns on the current control switch 750 so that the current supplied from the first heating wire control unit 701 is supplied to the second longitudinal heating wire 732 .

The first and second thermal concentration sensing units 741 and 742 may be disposed at both ends of each of the longitudinal heating lines.

Patients may need to twist their bodies sideways according to the doctor's requirements during dental treatment and maintain their posture for a certain period of time in that position. In this case, as the shoulder portion of the patient pushes the hot-wire mats 700, the temperature may rise in the crushed area. In this case, the flow plate 770 is moved by the pressure due to the crushing of the shoulder portion of the patient, and the heat concentration sensing unit 740 senses this, and the first heat ray control unit 701 senses the second heat ray 732, It is possible to prevent the heat from being concentrated in the shoulder region of the patient who is crushed by the hot-wire mat 700. [

When the first heating wire control unit 701 senses that the first and second plate flow sensing switches 779a and 779b are turned on, the first heating wire control unit 701 turns off the current control switch 750 and supplies the first heating wire 703 Can be reduced. That is, since the total length of the first heating line 703 to which the current is supplied is reduced in accordance with the turn-off of the current control switch 750, it is possible to prevent the problem of the heat ray damage to the overcurrent as the supply current is reduced in proportion thereto .
