Peeling and adhering the upper surface to each other against the bottom of the cushion nonwoven layer attached to the bottom of the carpet layer in step (a), and (f) the bottom nonwoven layer, sponge layer, aluminum layer, And surrounding the edges of the laminate in which the cushion nonwoven layer and the carpet layer are laminated, and surrounding the edges with a finishing member to fix the finishing members to the edges of the laminate.

Hereinafter, with reference to the embodiment shown in the drawings will be described in more detail the heat transfer carpet according to the present invention and its manufacturing method.

1 is an exploded perspective view showing a heat transfer carpet according to an embodiment of the present invention, Figure 2 is a cross-sectional view showing a heat transfer carpet according to an embodiment of the present invention.

Referring to the drawings, the heat transfer carpet 1 according to an embodiment of the present invention, the bottom nonwoven fabric layer 10, sponge layer 20, heating wire 30, aluminum layer 40, cushion nonwoven fabric layer 50, It comprises a carpet layer 60, and the finishing member 70.

The bottom nonwoven fabric layer 10 is a sheet member whose bottom surface is an anti-slip treatment member, which is located at the bottom layer of the heat transfer carpet 1 according to an embodiment of the present invention, and the bottom surface thereof is in contact with the floor of a living room or a room. Therefore, the bottom surface of the bottom nonwoven fabric layer 10 is preferably a non-slip treatment so that the heat transfer carpet 1 does not slip on the floor or the like. In the anti-slip treatment, a resin material having a high coefficient of friction may be applied to the bottom of the bottom nonwoven fabric 10, or a method of increasing the coefficient of friction by forming irregularities on the bottom of the bottom nonwoven fabric 10 may be used.

The sponge layer 20 is attached to the top surface of the bottom nonwoven layer as a sheet member of a heat insulating and flame retardant material. Since the heating wire 30 is positioned above the sponge layer 20, the sponge layer 20 should be made of a heat insulating and flame retardant material. The bottom nonwoven fabric layer 10 and the sponge layer 20 may be attached using an adhesive, but are easily attached to each other by thermal fusion. The heat fusion is simply performed by the heat laminating roller 3 (see Fig. 3). On the other hand, the sponge layer 20 is configured to allow the heating wire 30 to penetrate so that the heating wire 30 positioned thereon does not bleed into the carpet layer 60. When the heating wire 30 is raised to the carpet layer 60, which is the uppermost layer, the user may sense unevenness due to the wiring of the heating wire 30, thereby reducing comfort. The sponge layer 20 is deformed when the heating wire 30 positioned thereon is recessed. Accordingly, the heating wire 30 does not come to the carpet layer 60. Thus, the sponge layer 20 preferably has a thickness sufficient to allow the heating wire 30 positioned thereon to penetrate.

The heating wire 30 is wired on the upper surface of the sponge layer 20 to generate heat when a current is applied from a predetermined power source. The current supplied to the heating wire 30 is regulated by a predetermined controller (not shown in the figure).

The aluminum layer 40 is a sheet member made of aluminum and attached to the upper surface of the sponge layer 20 so that the heating wire 30 lies between the sponge layer 20. Since the aluminum layer 40 is made of metallic aluminum, electromagnetic waves generated from the heating wire 30 are prevented from propagating upward. In addition, the aluminum layer 40 serves as a waterproof layer. The aluminum layer 40 is attached to the upper surface of the sponge layer 20, the cushion nonwoven fabric layer 50 is attached to the upper surface. The aluminum layer 40, the sponge layer 20, the aluminum layer 40, and the cushion nonwoven fabric layer 50 are adhered to each other by an adhesive applied to each of the top and bottom surfaces of the aluminum layer 40.

The cushion nonwoven fabric layer 50 is positioned below the carpet layer 60 to improve the cushioning of the heat transfer carpet 1 according to an embodiment of the present invention, and at the same time the heating wire 30 is the carpet layer 60. It is to prevent the drooping to the top of the.

The carpet layer 60 is a sheet member made of a carpet material, and a bottom surface thereof is attached to an upper surface of the cushion nonwoven fabric 50. The carpet layer 60 and the cushion sub-porous layer 50 may be attached using an adhesive, but are easily attached to each other by thermal fusion.

The finishing member 70 is for finishing the edge of the laminate formed by laminating the bottom nonwoven fabric layer 10, sponge layer 20, aluminum layer 40, cushion nonwoven fabric layer 50 and the carpet layer 60 The circumference is fixed to surround the edge of the stack.

On the other hand, Figure 3 is a flow chart illustrating a method of manufacturing a heat transfer carpet according to an embodiment of the present invention.

Referring to the drawings, a method for manufacturing an electrothermal carpet according to an embodiment of the present invention comprises the following steps.

Step (a): The carpet layer 60, which is the sheet member of the carpet material, is superimposed on the upper surface of the cushion nonwoven fabric layer 50, which is the cushion member, and the contact surfaces are thermally bonded to each other.

Step (b) is a step of thermally bonding the contact surfaces to each other by superimposing a sponge layer 20 of a sheet member of a heat insulating and flame retardant material on an upper surface of the bottom nonwoven fabric layer 10 of a sheet member of which a bottom surface is an anti-slip treatment.

Step (c): The release paper of the bottom surface of the sheet member aluminum layer 40 made of aluminum on which adhesive is applied on both sides and a release paper (not shown) is attached thereto, and the heating wire 30 is seated on the bottom surface. To attach.

Step (d): In step (c), the bottom surface of the aluminum layer 40 on which the heating wire 30 is seated is attached to the top surface of the sponge layer 20 attached to the top surface of the bottom nonwoven fabric layer 10 in step (b). This is the step of bonding together.

Step (e): The release paper of the upper surface of the aluminum layer 40 attached to the upper surface of the sponge layer 20 is peeled off in step (d), and the upper surface is attached to the bottom surface of the carpet layer 60 in step (a). The bottom surface of the cushioned nonwoven fabric layer 50 is bonded to each other.

Step (f): In step (e), rounding the edge of the laminate in which the bottom nonwoven layer 10, the sponge layer 20, the aluminum layer 40, the cushion nonwoven layer 50 and the carpet layer 60 are laminated. The edge is wrapped with the finishing member 70 to fix the finishing member 70 to the edge of the stack.

By the above configuration, the heat transfer carpet according to the present invention has an advantage that the heating wire is provided as well as suitable for use in the living room as a normal carpet.

In addition, the heat transfer carpet according to the present invention is provided with a cushion non-woven fabric layer of the cushion material at the bottom of the carpet layer, which is the uppermost layer, and a sponge layer in which the heating wire is indented in the lower part of the heating wire is exposed to the carpet layer. Not only comfortable, but also has an aluminum layer on top of the heating wire has the advantage that the electromagnetic shielding and waterproof is possible.

In addition, the method of manufacturing the heat transfer carpet according to the present invention is easy to the interlayer adhesion by using heat fusion and adhesive to the adhesion between the layers of the heat transfer carpet. In particular, by attaching the heating wire to the bottom surface of the adhesive-coated aluminum layer has the advantage that the wiring of the heating wire is easy.

The heat-carrying carpet described above and shown in the drawings and a method of manufacturing the same are just one embodiment for describing the present invention, and should not be construed as limiting the technical idea of the present invention.
