Abstract

An infrared warmer device may include a touch sensor unit including a detecting wire mounted adjacent to a heating layer; a temperature sensor unit mounted adjacent to the heating layer; a cover covering the heating layer, an electrode unit, the touch sensor unit, and a temperature sensor unit; and a control unit controlling an amount of electric power supplied through the electrode unit such that a temperature detected by the temperature sensor unit reaches a target temperature, and changing the target temperature to a safe temperature when a touch of a body is detected through the touch sensor unit.

Claims17

Dependent claims

An infrared warmer device comprising:

a heating layer including a plurality of heating wires spaced from one another;
an electrode connected to the heating layer to supply electric power to the heating wires;
a touch sensor including a detecting wire mounted adjacent to the heating layer;
a temperature sensor mounted adjacent to the heating layer to detect a temperature of the heating layer;
a cover covering the heating layer, the electrode, the touch sensor, and the temperature sensor;
and
a controller configured of controlling an amount of the electric power supplied through the electrode to the heating layer so that the temperature detected by the temperature sensor reaches a target temperature, and of changing the target temperature to a predetermined temperature upon determining that a contact to the touch sensor is detected through the touch sensor.

4 more elements

A method for controlling an infrared warmer device, the method comprising:

obtaining, by a controller, a value of a temperature of a heating layer detected via a temperature sensor;
supplying, by the controller, electric power to the heating layer through an electrode;
controlling, by the controller, an amount of the electric power supplied from the electrode so that the detected temperature reaches a target temperature;
determining, by the controller, a contact to a touch sensor;
changing the target temperature to a predetermined temperature, upon determining that the contact of the touch sensor is detected;
and
controlling the amount of the electric power supplied from the electrode to the heating layer so that the detected temperature reaches a predetermined temperature.
