本发明涉及一种用于防止冻结的加热垫。 根据本发明的实施例，用于防止冻结的加热垫包括：位于底部的第一橡胶板; 形成在第一橡胶板的上侧的第二橡胶板; 电加热单元，其被电加热并形成在所述第二橡胶板的上侧; 位于电加热单元的上侧的金属网，并传递由电加热单元产生的热量; 形成在所述金属网的上侧并具有导热性的第三橡胶板; 以及温度变化单元，其涂覆在第三橡胶板的上侧，并且根据温度指示预定符号，字符，特征及其组合中的至少一个。 因此，当积雪堆积在底垫上时，加热垫可以通过电加热来防止雪冻结。

The present invention relates to a freezing prevention heating pad, freezing prevention heating pad according to the embodiment of the present invention, a first rubber plate which is located on the floor, it is formed on the first rubber plate second rubber plate having a thermal conductivity properties and , and the heat transfer portion is formed on top of the second rubber plate which generates heat by electricity, a metal net, and is formed on the metal net thermal conductivity properties, which is located on the heat transfer of the upper transfer heat generated from the heat conductive portion includes having a third and a rubber plate, a rubber plate and the third symbol is applied to the upper pre-set according to the temperature of, characters, shapes, and parts thereof that are at least one thermochromic the saliency of the combination.
Accordingly, when the build-up of snow on the floor mat can be prevented from freezing formed by dissolving through the heat generated by the electricity.
