Description

Heat mat having air convection including the upper and bottom air net material

The present invention relates to a warm mat, and more particularly, to a warm mat which includes a heating body embedded between mutually joined surfaces of an upper air-permeable structure and a lower air-permeable structure to have an air convection structure, And conveys heat generated from the heating element through the space formed around the heating element to the entire area of the mat.

The thermal mat widely used for thermal insulation is generally composed of a heating element that generates heat according to power application, and a heat insulating material surrounding the heating element or attached to upper and lower portions of the heating element, and a coating layer formed on the outside of the thermal insulation material.

At this time, heat generated from the heating element is transferred to the coating layer through a heat insulating material to generate a heating effect.

However, since the heat transfer method using the conduction method of the heat has a structure in which the heat generating body is embedded in the heat insulating material and the covering layer, there is a possibility that only the heat generating body is heated locally, and in a severe case, a fire accident may occur.

In addition, since the heat transfer is performed by the heat conduction method, there is also a disadvantage that the heat temperature decreases as the distance from the heating element is farther in the entire area of the mat.

The present invention was devised to solve the above drawbacks, and by using the conduction phenomenon, which is a heat transfer method in a conventional thermal mat, by forming an air convection structure of heat generated in the heating element inside the mat, heat transfer is radiated. And not only conduction but also by the convection method through the air convection structure provides a configuration of the thermal mat capable of performing efficient and uniform heat transfer.

In addition, the present invention provides a construction of a heating mat suitable for use in all seasons, so that the user can comfortably and conveniently perform the thermal therapy in the winter season as well as during the winter season.

The construction of the thermal mat of the present invention for achieving the above technical problem, by having a heating element inside the structure having a breathable located in the upper and lower parts to have an air convection structure, through the breathable structure At the same time, the heat generated from the heating element is convection to the entire area of the mat through the space portion formed around the heating element.

The heat mats according to the present invention having the above-described structure radiate heat generated from the heating element to the upper and lower air-permeable structures and conduct heat to the entire area of the mat through the space formed around the heating elements, It is possible to solve the problem that only the vicinity of the heating element pointed out as a disadvantage of the conventional warm mat can be locally heated, thereby preventing a fire accident caused by local heating in advance.

Further, since the heat of the heating element is transferred to the entire area of the mat by the convection method, the uniform temperature can be maintained throughout the entire area of the mat regardless of the distance from the heating element, and the thermal efficiency can be improved.

In addition, since the upper and lower surfaces of the heating mat are formed of a network structure made of a breathable structure, the user is provided with a cooling sensation in addition to a thermal sensation, thereby enabling the user to perform thermal therapy conveniently in the winter season as well as during the winter season It is a very advanced invention.
