Problems to be Solved by the Invention According to the above conventional configuration, only the periphery of the heater wire 42 arranged in a meandering manner is heated, that is, local heating occurs.
There is a problem that low-temperature burns occur.

Further, if the heater wire 42 is broken at even one point, the heating effect cannot be expected. Therefore, when cut to adjust to indoor dimensions, it cannot be used for heating purposes. If there is a weak point in a heat generating part such as the heater wire 42, it will be cut and a short circuit will cause an arc to blow, which may cause a fire problem.

The purpose of the present invention is to uniformly heat the entire surface of the helmet,
Moreover, even if it is cut, there will be no breakage of the heater part.
Furthermore, the current always flows smoothly and reliably without generating light such as Show 1~! [And, the object of the present invention is to provide a floor l with a heater that can firmly connect the upper and lower parts when the heater device is ignited.

Means for Solving the Problems In order to achieve the above object, the heater-containing floor l according to the invention 6 has a heater device on the white root, which comprises a pair of strip-shaped electrodes and a heating element layer that conducts between both strip-shaped electrodes. The strip electrodes are arranged in a groove formed on the upper surface of the base plate, and the heat generating layer is formed between the base plate and the upper surface of both strip electrodes, and between both strip electrodes and between the strip electrodes. A decorative sheet is laminated on the heater device with a pattern in which voids are present at a plurality of locations in the length direction.

According to the configuration of the present invention, when a voltage is applied to the heater device, a current flows throughout the heater device and generates heat, so that the entire surface of the floor system is uniformly heated.

Further, in the heater device, the heating element layer can be formed in the flanges 1 by disposing the band-shaped electrodes in the grooves. In addition, the area of the heating element layer where there is a void is smaller than the joint area of the joint between the strip electrode and the heating element layer, which are made of different materials. It will arise from the existence part. Furthermore, by positioning the adhesive member in the empty space, the empty space can be used to connect the base plate located below the heater device and the decorative sheet side located above.

as a substrate, a thermosetting resin layer 9 and a strip electrode 12.13
A heating element layer 21 is formed between the upper surfaces of the heating element layer 2 and
1 is formed of a film made of a mixture of powdery nokopon, powdery conductive ore, powdery semiconductor ceramic, resin, metal oxides, zirconia, and the like. At this time, the heating element layer 21 is formed in a pattern in which voids 22 are present at multiple locations in the middle between both strip electrodes 12.13 and in the length direction of the strip electrodes 12.13. The powdery carbon, metal oxides, and zirconia emit and reflect far infrared rays, and all or some of these are mixed. These strip electrodes 12, 13, heating layer 27, etc. form a heater device 23 that emits far infrared rays. Then, a surface base plate 24 made of, for example, a phase detector and for covering the surface of the heater device 23 is laminated on the heating element layer 21 with a thermosetting resin layer 25 interposed therebetween. At this time, the naturally curable resin layer 9.25 is bonded through the cavity 22, thereby increasing the layer strength. A decorative sheet 27 is laminated on the surface base plate 24 with an insulating resin layer 26 interposed therebetween. This decorative sheet 27 may be made of, for example, a thin plate made of natural wood or a thin plate made of resin.
Made of paper, etc. An outer skin layer 28 is formed on all exposed surfaces of the base plate 1, decorative sheet 27, etc., and is made of a resin layer that emits far infrared rays and is made by mixing a resin of the same quality as the resin 5 with a far infrared ray emitting material such as Silcor or metal oxide. Ru. The heater-containing floor material 31 is constructed as described above.

In manufacturing such a heater-containing floor material 31, first, a back base plate 3 is laminated on the back base plate 3, which is formed by laminating a plurality of wooden veneers, and an intermediate base plate is attached via the resin 5. 4 are laminated to form the base plate 1. Next, grooves 10.11 and stepped through holes 8 are formed at predetermined locations on this intermediate base plate 4. Then, the thermosetting resin layer 9 is laminated and covered, for example, by coating using a roller or by spraying. At this time, the thermosetting resin layer 9 is also formed on the wood grain 4a of the intermediate base plate 4, but the groove of the wood grain 4a is not completely covered, and the same wood grain 4a remains.

Next, the mount member 18 is fitted into the stepped through hole 8, and the thermosetting resin layer 9 is fixed using an adhesive.

Then, a strip electrode 12.13 is placed in the hole 10.11 and fixed with an adhesive.
, 13b are matched with the penetration portion of the mount member 18, and are oriented so that the length direction is in the direction B perpendicular to the grain direction. Next, the pin 19 is driven so that the inner cylindrical part 19a passes through the holes 12a and 13a and into the cylindrical part 18a. By this driving, the annular convex part 19c is fitted into the annular four part 18c, and both parts 18.19 are strongly connected, and the strip electrode 12.13 is strongly held between the inclined concave part 18d and the head part 19b. and heating element layer 21
are laminated by coating or spraying,
At this time, the above-mentioned void space 22 will be formed. A surface base plate 24 is laminated on this heating element layer 21 via a thermosetting resin layer 25, and an insulating resin layer 26 is laminated on the surface base plate 24 by coating or spraying, and then a decorative sheet 27 is laid. Then, the outer skin layer 28 is formed by coating or spraying.

The heater-containing floor material 31 configured in this way is
The concave grooves 6 and the protrusions 7 are fitted together and arranged on the joist 32. Then, screw the round terminals 16a and 17a located on the large diameter part 8C on the back side into the screw hole 19d.
By intertwining J20a, the operating head 20 of the screw 20
The tightening is fixed by b. 33 indicates a support book, and 34 indicates a nail.

When using the heated floor material 31, a predetermined voltage is applied between the strip electrodes 12 and 13 via the control device.

As a result, current flows in the wood grain direction A throughout the heating element layer 21, and the entire surface of the heating element layer 21 generates heat.
, is transmitted to the outer skin layer 28 and heated floor material 31
This results in uniform heating of the entire surface. At this time, the base plate 1 is also heated, but in this case, since it is waterproof sealed by the outer skin layer 28, the moisture contained therein will not escape.

In such a state of use, the heater device 23 emits far-infrared energy in addition to thermal energy. In other words, far infrared rays
After passing through the outer skin layer 28, it is radiated into the room. Here, far infrared rays react with moisture, so when a person containing a large amount of moisture enters a room, the human body will be warmed by the reaction, and therefore the thermal energy of the device 23 will be increased. Sufficient heating is possible while suppressing temperature rise. In other words, although the interior of the room is somewhat cool, the human body is sufficiently warmed.

By coating the surface of the decorative sheet 27 with zirconia (fine powder) using urethane, the energy of the wood of each veneer itself can be released.

As mentioned above, the intermediate base plate 4 is f410.11 is formed, and a strip electrode 12.13 is arranged in this groove 1 (1, 11). It is possible to prevent the occurrence of cracks at weak points in the body layer 21. That is, for example, as shown in FIG.
As shown in FIG. 8, a strip electrode 1 is provided on the upper surface side of the intermediate base plate 4
When the electrode 2.13 is arranged in a protruding manner and the heating element layer 21 is laminated on the entire surface, the strip electrode 12.1 is made of a different material.
The joint between 3 and the heating element layer 21 becomes a weak point 1-P, and cracks will occur from the weak point 1-P with the passage of use. This causes the weak point hP portion to break and short circuit, causing the arc to break and the base plates 4 and 24 to burn. On the other hand, in the above embodiment, as shown in FIGS. 3 and 4, the area S of the heating element layer 21 in the portion where the void 22 is present is smaller than the bonding area S of the bonding portion, so it is difficult to use the As the process progresses, cranks will occur from the empty space. Cutting due to this crack does not cause short circuits because the material is the same, and even if no heat is generated at the cut portion, the overall heat generation effect does not deteriorate significantly.

FIG. 5t shows another embodiment 2 in which a far-infrared reflector 36 is interposed. That is, the far-infrared reflecting plate 36 is interposed, for example, between the core material 2 and the intermediate base plate 4, and is formed in the form of a film 8 of aluminum or the like, and insulating resin layers 37 and 38 are interposed when laminating the plate. be done.

According to this other embodiment, the far infrared rays X emitted from the upper surface side are the same as those described above, and the far infrared rays Y emitted from the lower surface side are reflected by the far infrared reflecting plate 36 after passing through the intermediate base plate 4. Then, the light is reflected by the reflecting plate 36, passes through the intermediate base plate 4, the heater device 23, the front base plate 24, etc., and is then radiated into the room. This improves the far-infrared effect.1
qru.

Note that by removing the arc 39 from the reflection plate 36, insulation becomes effective.

By constructing the base plate 1 by laminating the back base plate 3 and the intermediate base plate 4 on the core material 2 as described in the above embodiment, bending of the base material 1 can be prevented. Thereby, the heater-containing floor material 31 can be protected and its service life can be improved. That is, for example, if only the core material 2 is used,
When the temperature rises, thermal deformation of each unit causes cuts in the opposing contact parts.

3 In the heating element layer 21, the shear heat bath horn becomes high at this cut, and cracks occur. On the other hand, when the base plate 1 that does not bend as described above is used, the shear heat stress can be almost equalized over the entire surface, and the occurrence of cracks can be prevented.

In addition, both base plates 3 and 4 may be replaced with S fiber reinforced resin plates,
In this case, heat resistance can be increased.

During use as described above, even if current does not flow in some areas due to some reason or malfunction, current will flow in most of the remaining areas and generate heat. As a result, the entire surface can be heated without any problem.

In addition, when installing the heater-containing floor material 31 indoors,
Adjustment with the indoor dimensions may be necessary (although it may be necessary to cut the heater-containing flooring material 31 to the desired dimensions in the length direction, leaving both the connecting fittings 15 in place). On the surface, the aforementioned outer skin layer 28 is formed by coating.

As described in the above embodiment, when the heater device 23 is turned off, the far infrared rays X emitted from the top side of the heater device 23 can be transmitted through the decorative sheet 27 and then radiated into the room. Therefore, the people in the room will be warmed by the reaction of the far infrared rays By installing the plate 36, the far infrared rays Y emitted from the bottom side are reflected by the reflector 36 and then radiated into the room, thereby directing most of the far infrared rays from the heater device 23 into the room. can be radiated to.

Effects of the Invention According to the present invention having the above configuration, by applying a voltage to the heater device, a current can be passed throughout the heater device to generate heat, and the entire surface of the old floor can be uniformly warmed. This eliminates local heating and completely prevents low-temperature burns. Further, in the heater device, the heating element layer can be formed flat by arranging the band-shaped electrode in the groove, and can be easily formed into a plate shape. In addition, since the area of the heating element layer where the void exists can be made smaller than the joint area of the joining part between the strip electrode and the heating element layer, which are made of different materials, cracks will not occur over time. Since the occurrence of voids is covered, and cutting due to cracks is treated as the same, short circuits do not occur, and it is possible to prevent arcs from breaking and burning the base plate.

Furthermore, by positioning the adhesive member using the empty space, it is possible to firmly connect the base plate located below the heater device to the decorative sheet side located above.

Furthermore, by using a plate-shaped heater device, the desired heating effect can always be expected even when cutting into desired dimensions.
