A Heat Control System of built in Car Seat

摘要

The present invention allows the user to arbitrarily adjust the temperature of the heating sheet in the heating sheet which is heated by receiving power from the vehicle and detects the abnormality of the heating sheet and controls the power supplied to the heating sheet. The temperature control system of the sheet.;The temperature control system of the hot wire sheet for a vehicle of the present invention is a power output unit for outputting the set control power (VCC) by converting the hot wire power (VDD) and the hot wire power (VDD) supplied through the power supply unit 10 of the vehicle to a constant voltage 30; A hot wire unit 40 generating heat by receiving heat wire power VDD output through the power output unit 30 to generate heat; A temperature detection sensor 50 for sensing a temperature generated by heat generation of the hot wire part 40; A temperature setting unit 60 for setting a heating temperature of the heating unit 40 by adjusting a voltage value of a control power supply VDD supplied from the power output unit 30; Comparator 71 for comparing the detected temperature transmitted from the temperature sensor 50 and the set temperature set by the temperature setting unit 60 and the heating wire unit 40 when the detected temperature of the comparator is lower than the set temperature. A control unit 70 provided with a controller 72 for operating the heating unit and blocking the operation of the heating unit 40 when the sensing temperature is higher than the set temperature; And an operation display unit 90 for displaying the power supply state of the power supply unit 10 and the operation state of the circuit.
