1 is a configuration diagram of a heat insulating mat according to a first embodiment of the present invention, Figure 2 is a cross-sectional view of the heat insulating mat according to a first embodiment of the present invention.

As shown in the heat insulating mat according to the first embodiment of the present invention, the heat generating portion 10 for generating heat and at least one cushion layer 20 for imparting a cushion feeling, and the lower portion than the heat generating portion 10 At least one heat insulating layer 30 may be stacked and formed to be insulated from the floor.

That is, even if the heat insulating mat of the present invention directly touches a cold floor, since heat transfer between the heat generating part 10 and the floor may be blocked by the heat insulating layer 30, the loss of heat generated by the heat generating part 10 is reduced. Can be prevented.

On the other hand, the heat generating unit 10 may be configured using any kind of electricity, hot water, etc., as long as it can supply a heat source, in the present embodiment may include a heating wire 12 for generating heat by electric resistance as using electricity. have.

The heating wire 12 may be installed in various ways, and may be integrated with the cushion layer 20 by a method of sewing the heating wire 12 to the cushion layer 20 as in the present embodiment rather than a bonding method using a bonding agent. It is more preferable because it is simpler and easier to prevent harmful substances and damage to the cushion layer 20. At this time, the heating wire 12 may be integrated in the middle of the cushion layer 20, as shown, may be integrated into the upper portion or the lower portion of the cushion layer 20 as necessary.

The heating wire 12 may be installed in various shapes, and may be installed in a zigzag shape as in the present embodiment.

The cushion layer 20 may be composed of a plurality of cushion layers 20 as shown in FIG. 3 and FIG.

The cushion layer 20 may be formed by various cushioning materials, and in particular, the cushion layer 20 may be formed of the nonwoven fabric 22 as in the present embodiment. Of course, if necessary, the cushion layer 20 may be formed of a sponge or styrofoam, or may be formed of two or more cushioning materials.

The heat insulating material may be any one as long as it has heat insulating property, and particularly preferably made of silver foil. That is, by blocking the air flow between the heat generating portion 110 and the bottom by the silver foil heat insulating material and thermal conductivity, heat by the heat generating portion 110 intensively transferred only to the upper portion is excellent in heat insulation.

As described above, when the lower cushion layer 126 is formed of the nonwoven fabric as described above, the lower cushion layer 126 is formed by a needle punching method rather than a bonding method or a laminating method. More preferably). That is, as indicated by 'A' of FIG. 4, the seam B of the nonwoven fabric of the lower cushion layer 126 is squeezed toward the heat generating unit 110 by needle punching, and is entangled in the heat insulating layer 130, thereby providing a heat insulating layer 130. ) And the lower cushion layer 126 may be integrated.

In addition, the heat insulating material as described above can be made by vinyl as the bonding by the needle punching method. When vinyl is used as a heat insulating material, the following advantages can be further obtained. That is, when the needle is embedded in the vinyl during needle punching, the needle punching portion of the vinyl is stretched in the direction in which the needle is embedded. Since the needle punching part of the heat insulating material can be sealed, it is possible to prevent heat loss through the needle punching part of the heat insulating material.

In addition, the heat insulation layer 130 may be combined with the lower cushion layer 126 as well as the heat generating unit 110 by a laminating method using a seam B of a nonwoven fabric generated by a needle punching method. As described above, even in a situation where direct coupling between the heat insulation layer 130 and the heat generation unit 110 is difficult or a special method is required for direct coupling due to the material properties of the heat insulation layer 130 or the heat generating unit 110, the heat insulation layer as described above. The 130 and the heat generating unit 110 may be easily and firmly coupled, and the material limitation of the heat insulating layer 130 may be eliminated due to the manufacturing problem described above. Of course, even if the heat insulation layer 130 and the heat generating unit 110 is directly coupled, the heat insulation layer 130 and the heat generating unit 1100 may be more firmly coupled by a laminating method using a seam B of the nonwoven fabric as described above. have.

Meanwhile, as another embodiment, another member layer may be stacked between the heat insulating layer 130 and the heat generating unit 110 for safety and antibacterial properties, and in this case, the heat insulating layer 130 and the other member layer may have material properties. Without being limited to the back, as described above, it can be easily and firmly coupled by a laminating method using the seam (B) of the nonwoven fabric.

In the insulating mat of the present invention, a plurality of dots 150 for slipping may be formed on the bottom of the lower cushion layer 126 forming the bottom layer of the insulating mat. The plurality of dots 150 may be formed in various ways. For example, the plurality of dots 150 may be formed on the bottom surface of the lower cushion layer 126 after being deposited in the liquid phase of the lower cushion layer 126 and then undergoing an evaporation fixing process. .

Hereinafter, a third embodiment of the present invention will be described in detail with reference to FIGS. 6 and 7.

Furthermore, at least one heat generating unit in which at least one of the lower cushion layer 210 and the upper cushion layer 220 may be installed by inserting the heat generating unit 230 in contact with each other to install the heat generating unit 240. Insert grooves (212, 222) is characterized in that formed.

In this way, the heat generating unit 230 is integrated with the lower cushion layer 210 and the upper cushion layer 220, so that the heating unit 230 is formed on the upper cushion layer 220 by the cushioning of the upper cushion layer 220. Since it may not be exposed to the laminated cardboard 240 to be stacked, a configuration such as a separate plate for installing the heat generating unit 230 may be omitted.

Therefore, the manufacturing cost can be reduced, and heat transfer of the heat generating unit 230 to the sheetboard 240 can be made easier, thereby ensuring rapid initial warming and excellent warming, and significantly reducing the maintenance cost by reducing the heat loss. can do.

In addition, as long as the heat generating portion 230 is placed on the heat generating portion insertion grooves 212 and 222, since it can be easily installed, manufacturability can be improved.

The heating part insertion grooves 212 and 222 for this may be formed in both the lower cushion layer 210 and the upper cushion layer 220 as shown, but only the lower cushion layer 210 or the upper cushion layer ( 220 may be formed only.

The heating unit insertion grooves 212 and 222 may take various shapes, but it is more preferable that the heating unit insertion grooves 212 and 222 be linearly formed so as to easily and simply install the heating unit 230 as one.

In addition, the heat generating unit for heat generation of the heat generating unit 230 is preferably installed outside the heat insulating mat of the present invention, so that the heat generating unit 230 can be easily connected to the heat generating driving unit, the linear heat generating unit insertion grooves 212 and 222. ) May be formed so as to start at one edge of the lower and upper cushion layers 210 and 220 and end at the other edge of the lower and upper cushion layers 210 and 220.

The linear heating portion insertion grooves 212 and 222 may have a zigzag shape as shown in the figure, and may also take various shapes such as a straight line and a wave shape.

The heating unit insertion grooves 212 and 222 may be formed to correspond to the cross section of the heating unit 230 in order to prevent the flow of the heating unit 230. That is, when the heat generating unit 230 is formed in a circular cross section as shown, the heat generating unit insertion grooves 212 and 222 may also be formed in a circular shape corresponding to the size of the heat generating unit 230.

The lower cushion layer 210 and the upper cushion layer 220 may be formed of various materials, and are more preferably formed of a nonwoven material as described above in the first and second embodiments.

The heating unit 230 may be at least one of a hot water pipe or a heating wire. At this time, when the heat generating unit 230 is composed of a hot water pipe 232, compared to the second embodiment described above, the lower cushion layer 210 and the upper cushion layer 220 to install the hot water pipe 232 It can also serve as a plate for.

However, manufacturing the cushion layers 210 and 220 in which the heating part insertion grooves 212 and 222 are formed during the manufacturing process of the cushion layers 210 and 220 may further take advantages such as reducing material costs and eliminating the post-treatment process.

In the latter case, the cushion layers 210 and 220 in which the heating part insertion grooves 212 and 222 are formed may be manufactured in various ways, and as shown in FIG. 8, it may be more preferable to manufacture.
