However, the heating desk according to the prior art described above has a heating panel having a double structure in which a heater for radiation heating and a heater for conduction heating are provided on the lower back plate of the desk. By making it possible, radiant heating of the human leg toward the desk or conduction heating under the feet can be freely selected depending on environmental conditions at the time of use. The heat-generating panel simply has a radiant heating surface at the front and a conduction heating surface at the rear. The radiation heating heater is attached inside the radiation heating surface, and the conduction heating heater is adhered inside the conduction heating heater. Absent.

[0004] In view of the above, the present invention provides a heating mat in which even when a load is applied to the sheet heating plate, the internal large-capacity sheet heating element is not damaged. It is intended for.

According to the first aspect of the invention, a heat insulating material is laminated on a bottom plate made of a cold-rolled steel plate or the like, a large-capacity planar heating element is laminated on the heat insulating material, and the large-capacity planar heating element is further laminated. A protective means made of a material having good thermal conductivity is laminated on the upper part, and the surface is covered with a surface material such as cloth so as to cover the whole. According to the second aspect of the present invention, a heat insulating material is laminated on a bottom plate made of a cold-rolled steel plate or the like, an aluminum plate material is laminated on the heat insulating material, and a large-capacity planar heating element is formed on the aluminum plate material. And a protective material having a lower surface coated with a black paint or the like on the upper surface of the large-capacity planar heating element, and covering the entire surface with a surface material such as a cloth so as to cover the entire surface. It was adopted. According to a third aspect of the present invention, in the first or second aspect of the invention, a technical means is employed in which a plurality of heat radiation holes are formed in a protective material having improved thermal conductivity.

[0006]

According to the present invention, as a result of adopting the above technical means, the legs and feet can be warmed, and at the same time, there is no danger of damaging the heat generating panel even if a load is applied. Further, by covering with a protective material or the like made of a material having good heat conductivity provided with a plurality of heat dissipation holes for protecting the sheet heating element, the sheet heating element is not damaged.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below in detail with reference to the accompanying drawings. First, a specific example of a heating mat will be described with reference to FIGS.

FIG. 3 shows an embodiment of a spread mat in which a foot can be placed while wearing shoes. A flat heating element provided with a cord 7 connected to a power source is provided. . In addition, the one shown in FIG. 4 has both ends supported by support members 8 so that it is convenient to place a foot when working or studying at a desk or a work table, and has a slightly upward slope. It is an example of a footrest.

A first embodiment of the structure of the heating mat shown in the above specific example will be described in detail with reference to FIG.

A heat insulating material 2 having a certain thickness, such as urethane foam or glass wool, is laminated on a bottom plate 1 made of a cold-rolled steel sheet or the like, and an upper surface of the heat insulating material 2 is made of an electric heater panel or the like. Place the large-capacity planar heating element 3
A material having good thermal conductivity for protecting the large-capacity planar heating element 3 on the upper surface of the large-capacity planar heating element 3 and transmitting the heat generated by the planar heating element 3 to the upper portion, such as an aluminum plate material or a copper plate material. A plurality of heat-dissipating holes 4 are formed at appropriate places in the formed protective material 5, and the whole is covered with a surface material 6 such as a cloth having a soft surface.

As described above, since the upper and lower portions of the large-capacity planar heating element are sandwiched and protected by the protective material 5 and the heat insulating material 2, the heat rays of the large-capacity planar heating element are broken. The heat generated by the planar heating element does not leak to the lower part without causing the heat generation, so that the heat can be effectively used.

The large-capacity sheet heating element is energized by connecting a cord 7 from an outlet via a socket.
The thermostat incorporated in the sheet heating element can be automatically turned on and off to maintain a constant temperature.

Next, a second embodiment will be described in detail with reference to FIG. A heat insulating material 2 is laminated on a bottom plate 1 made of a cold-rolled steel plate or the like, and an aluminum plate material 1 is formed on the heat insulating material 2.
0, the large-capacity planar heating element 3 is laminated on the aluminum plate material 10, and the large-capacity planar heating element 3
Is a heating mat in which a protective material 9 whose lower surface is coated with a black paint or the like is laminated on the upper surface of the upper surface of the upper surface, and is covered with a surface material 6 such as a cloth so as to cover the entirety. In this case, the heating efficiency is further improved by applying a black paint on the upper part of the planar heating element 3 to improve heat conduction.

[0014]

According to the present invention, as a result of employing the above configuration,
The following effects can be obtained. (1) Since the planar heating element that is most easily damaged is sandwiched and protected from above and below by a protective material and a heat insulating material, the planar heating element is not damaged even when a load is applied. (2) Since a heat insulating material is used in the lower part of the planar heating element, heat does not leak to the lower part, and an effective heating action is achieved.
