Description

TECHNICAL FIELD [0001] The present invention relates to a heating mat having a graphen sheet,

The present invention relates to an exothermic mat provided with a graphen sheet. More particularly, the present invention relates to a heating mat having a graphene sheet having graphene sheets embedded in a heating mat to raise the temperature of the heating wire as quickly as possible and to transmit heat energy efficiently to a user will be.

Generally, a heat-generating mat using electric energy is mainly used for identification devices, and a cover having a certain thickness is formed in a space between an outer shell and an inner shell, and a heating wire is arranged in a zigzag shape on the upper side of the cushion layer, And an electromagnetic wave shielding member for shielding electromagnetic waves is further provided on the upper side thereof.

In addition, heat mats allow the body to be connected to the inner skin, while tourmaline and germanium are added to the inner skin along with jade, loess, and male, which emit far-infrared rays and near-infrared rays and negative ions, thereby increasing the body temperature of the laid body. It penetrates the skin to relieve muscle pain and improve blood circulation.

Accordingly, Korean Utility Model Registration No. 20-0303193 (hereinafter referred to as Prior Art Document 1) has filed a multi-function mat application.

More specifically, as shown in FIG. 1, the multifunctional mat includes a sponge 50, a surface 60, and a heating wire 70 laminated inward, and a temperature sensor (not shown) And a negative electric potential plate 80 for generating a negative electric potential and having a predetermined space on the inner side so as to include the sponge 50, the plunge face 60, and the heating line 70, A casing 10 in which a plurality of brackets 13 having a mounting space 13a are mounted so that a radiator 11 radiating far infrared rays is mounted on the casing 10; A plurality of solenoids 20 divided into left and right sides of the outer envelope 10, a superhigh-frequency core 30 provided in a plurality of predetermined positions inside the envelope 10 so as to generate superharmonic waves, The heating wire 70, the solenoid 20, and the ultra short wave core 30 are electrically connected And a control unit (40) configured to control the left and right sides of the air mats.

However, the method basically raises the temperature of the human body due to the heat generated by the heating wire or the surface heating element, but since far infrared rays and anions generated by the far infrared ray and the anion emitting material can not penetrate deeply into the human body, It is not possible to relieve the fatigue of the muscles causing the pain. Especially, the infiltration time of the far infrared ray and the negative ion takes a long time, and it takes a lot of time to raise the temperature of the human body.

In this way, the existing heat-generating mat increases the temperature of the body by supplying electric energy to the heating wire or the surface heating element, but it is applied only to the skin layer, and the effect of the fundamental blood circulation improvement and the muscle pain relief is insignificant.

Although the cushioning member 161 has a predetermined thickness and the cushioning force as described above, the cushioning member 161 is not limited to the cushioning member but may be an elastic member having elasticity such as a spring.

The heating wire 163 formed between the cushioning member 161 and the electromagnetic wave shielding member 165 generates heat when supplied with electric energy, and an area heating element may be used.

Also, the supply of the electric energy is performed by using the controller so that the supply energy of the heating line 163 senses the heat generation temperature and automatically maintains the constant temperature.
