Description

HEATING MAT {HEATING MAT}

The present invention relates to a heat-generating mat with a heat-transfer sheet, more specifically, it is simple and easy to assemble and can improve productivity, and can be easily separated and cleaned, washed, repaired and replaced The present invention relates to a heat mats which can be used.

Generally, when a current flows in a conductor, an electromagnetic wave is generated which is adversely affecting the human body by the electric field and the magnetic field. Especially, various electric heaters that use electric energy such as heat mats, electric blanket, electric bed, electric bed, electric cushion, and electric fomentation are converted into thermal energy and used in direct contact with the human body.

Such a heat radiator has a so-called heat transfer sheet which radiates heat by the conduction heat of the heat generating body with good smoothness and durability by interposing a line-shaped heat conductor and an electric conductor having electrical resistance between the upper and lower insulating radiators on the surface.

When an insulating resin film such as PE, PP, PET, PVC, polyurethane or the like is used as the insulating material, moisture resistance can be ensured through lamination, and flexibility and flexibility can be ensured when a fabric is used.

When a metallic material such as nichrome, copper, nickel alloy, or aluminum is used as a heating element, local heat is generated only around the heating element, temperature deviation is large, physical properties are changed during overheating due to overload, When carbon black is used, it is required to meet the ideal combination of binder and proper standards, and since it is manufactured by painting and printing process, uniformity of thickness and size are limited, so that carbon thread ) Are mainly used.

In recent years, a structure has been proposed in which an electromagnetic shielding film is sandwiched between layers in order to shield electromagnetic waves from the heat-transfer sheet or a fabric formed by woven metal threads on a surface contacting the human body.

For example, a heat-generating mat using an electromagnetic wave shielding film disclosed in Korean Patent No. 10-1576545 includes a substrate on which at least one silver heating line, which is heated by a power source supplied from a power source, is printed, A thermoplastic polyurethane (TPU) film that shields the silver heating line and shields electromagnetic waves, a conductive fabric layered on top of the TPU film, and an electromagnetic shielding layer that is laminated on each of the conductive fabrics and shields electromagnetic waves generated from the heating wire A TPU electromagnetic wave shielding film and a Permalloy laminated on top of each TPU electromagnetic wave shielding film.

However, this is a structure in which a plurality of films and a fabric are attached to the upper and lower surfaces of the substrate in multiple layers, so that the entire thickness becomes too thick, which limits the use, handling and storage inconvenience.

On the other hand, the 'heat-generating mat having electromagnetic wave shielding function' disclosed in Korean Patent No. 10-1791647 includes a bottom layer 110 forming a bottom surface as shown in FIG. 1, An electromagnetic wave shielding layer 130 disposed on the heating line 120 and shielding electromagnetic waves emitted through the heating line 120, and an electromagnetic wave shielding layer 130 disposed on the electromagnetic wave shielding layer 130. [ And a controller 200 connected to the mat 100 through the connector 150 to control the overall operation of the mat 100.

However, due to the structural characteristics in which the bottom layer 110, the heating line 120, the shielding layer 130, and the cover layer 140 are integrally attached, it is very difficult and inconvenient to perform operations such as cleaning or washing at the time of contamination. In case of failure, it is necessary to separate and repair the parts, and then install them again. Therefore, maintenance and replacement are troublesome and troublesome.

Herein, the background art or the prior art described above is only intended to help understand the technical significance of the present invention as information acquired by the present inventor or derived from the present invention, It does not mean that it is widely known in the field.
