[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a heating mat laid between floors and a floor mat laid on the floor.

[0002]

[Prior art]

 New houses with floor heating are increasing. Floor heating tends to become more widespread, especially for comfortable winters in home kitchens and toilets. However, installing underfloor heating in an existing house requires relatively large-scale construction. Therefore, a simple floor heating device called a so-called hot carpet is widely used. On the other hand, floor heating can also be performed by using ordinary carpets and other rugs in use (these are collectively referred to as floor mats in the present invention). In this case, an electric heating type heat-generating sheet (this type of heat-generating sheet is collectively called an electric heater in the present invention) is laid under the floor mat.

[0003]

[Problems to be solved by the invention]

 By the way, the conventional techniques as described above have the following problems to be solved. If an electric heater is laid under a floor mat that has already been used and used for heating water around kitchens and toilets, prevent leakage due to water splashing and take sufficient measures against dirt There is a need. Also, when the floor mat is placed on the electric heater, if a person walks on it, the floor mat slides on the electric heater and moves, and it is necessary to frequently reposition the floor mat. As a countermeasure, floor mats and electric heaters are fixed using so-called magic fasteners. However, floor mats are often cleaned and washed, so it is desirable that the two be separated as easily as possible. Also, if the work of fixing and separating the two is repeated, there is a problem that the function of the fastener is reduced and the back surface of the floor mat is damaged.

[0006]

[Embodiment of the invention]

 As described above, the present invention prevents slippage between the floor mat and the electric heater by using the anti-slip sheet. On the other hand, considering the strength to withstand human treading pressure and measures to prevent leakage of water from spilled water, a composite sheet composed of an anti-slip sheet and an impermeable reinforcing sheet will be used. Hereinafter, embodiments of the present invention will be described using specific examples with reference to the drawings.

FIG. 1 is a view for explaining the heating mat of the present invention. FIG. 1A is a perspective view of a floor mat and a heating mat, and FIG. 1B is a cross-sectional view of a main part of the heating mat. The floor mat 1 is used by being laid on a heating mat 10. The floor mat 1 is a carpet or mat that is very commonly used. In particular, small objects used in kitchens and toilets often slide on the heating mat 10 and are suitable for implementing the present invention. The heating mat 10 includes the electric heater 2, the heat insulating sheet 3, and the protective cover 4 surrounding these. The electric heater 2 is connected to a power supply by a cord 8, a switch 9, and a plug 13.

As shown in FIG. 1B, a heat insulating sheet 3 is laminated on the surface of the electric heater 2 on the floor 20 side. The protective cover 4 is formed by molding a composite sheet in which the anti-slip sheet 41 and the water-impermeable reinforcing sheet 42 are laminated so that the outermost side becomes the anti-slip sheet 41. The anti-slip sheet 41 covers at least one surface of the water-impermeable reinforcing sheet 42, is softer than the water-impermeable reinforcing sheet 42 at room temperature, has a lower melting point than the water-impermeable reinforcing sheet 42, It is preferable that it is made of a plastic thin film thinner than the reinforcing sheet 42.

[0009] An example of a soft plastic having a low softening point is low molecular weight polyethylene which is frequently used for molded articles requiring elasticity. This type of plastic is mechanically and thermally weak. For this reason, the heating mat of the present invention used a composite sheet in which an anti-slip sheet 41 and an impermeable reinforcing sheet 42 were laminated. Since the anti-slip sheet 41 is flexible, the anti-slip sheet 41 fits well with the unevenness on the back surface of the floor mat 1 to be overlaid, and prevents slip on the overlapping surface. The plastic thin film having a lower softening point than the water-impermeable reinforcing sheet 42 is used for the anti-slip sheet 41 because heat sealing is easy when processed into a bag. Further, at the time of heat sealing, there is also an effect that only the portion of the anti-slip sheet 41 is melted and the water-impermeable reinforcing sheet 42 is not thermally damaged.

The anti-slip sheet 41 is arranged so as to cover at least the outermost side of the protective cover 4 as shown in FIG. This is to prevent slippage between the floor mat 1 and the heating mat 10 and also prevent slippage between the floor 20 and the heating mat 10. Further, as shown in the example of this figure, when the sheet is disposed so as to cover both surfaces of the water-impermeable reinforcing sheet 42, slip between the protective cover 4 and the electric heater 2 is prevented, and the protective cover 4 and the heat insulating sheet 4 are insulated. There is also an effect of preventing slippage between the seat 3.

FIG. 2 is an exploded perspective view of a specific example of the heating mat of the present invention. The electric heater 2 in the figure is a known far-infrared film heater. Electrodes 5 made of a copper plate are attached to both side edges of the electric heater 2, and a cord 8, a lead wire 6, and a thermostat 7 are connected to one end. The lead wire 6 and the thermostat 7 are accommodated in a groove 11 provided in the heat insulating sheet 3. The size of the electric heater 2 is adjusted, for example, to about 60 cm in length and 40 cm in width. The heat insulating sheet 3 is, for example, a glass wool sheet having a thickness of about 5 mm.

As the protective cover 4, for example, a composite sheet manufactured by Sunrivia was used. This is obtained by laminating an anti-slip sheet 41 made of polyethylene on both sides of an impermeable reinforcing sheet 42 made of polypropylene. 2 was heat-sealed and molded into a bag, and the electric heater 2 and the heat insulating sheet 3 were sealed. Of course, the structure of the composite sheet is not limited to this, and processing into a bag may be performed by heat sealing, stitching, or bonding. The seal may be anywhere on the protective cover 4. With the above configuration, a sufficient anti-slip effect was exhibited. In addition, since this type of heating mat is laid on the floor, it is easy to be damaged by dropping an object such as a kitchen knife. In this case, the protection cover 4 is removed, and the electric heater 2 is repaired. When the new protective cover 4 is attached again, the repair is completed. If the protective cover is configured as described above, it is inexpensive, and replacement does not greatly affect repair costs.

[0013]

[Effect of the invention]

 As described above, if the laminate of the electric heater 2 and the heat insulating sheet 3 is surrounded by the protective cover 4, slippage between the floor mat 1 and the heating mat 10 is prevented, and the floor 20 and the heating mat 10 are Can be prevented from slipping. Further, the protective cover 4 prevents the electric heater 2 and the heat insulating sheet 3 from being stained. Therefore, it is suitable for laying in kitchens and toilets. Further, since the protective cover 4 is waterproof, if the electric heater 2 and the heat insulating sheet 3 are surrounded and sealed, leakage of water due to spilled water is prevented, which contributes to safety. For example, if an antibacterial agent is added to the anti-slip sheet 41, it becomes more clean. If the anti-slip sheet 41 and the water-impermeable reinforcing sheet 42 are colored, a decorative effect can be expected.

Further, the shape and size of the heating mat of the present invention can be freely selected, so that the heating mat can be widely applied to cushions, futons and the like. In the present invention, the “floor” is not limited to the floor of a building, but includes any part on which a heating mat can be laid, such as a bed surface of a bed or a seat surface of a chair. The “floor mat” shall cover all common rugs such as carpets, carpets, cushions, toilet mats, kitchen mats and center rugs. If the heating mat of the present invention is adopted, the floor mat can be freely replaced or washed, and the floor mat is clean. In addition, since there is no need for on-site construction, it is easy to purchase and use in ordinary households. Further, when the protective cover 4 is damaged, it is easy to replace and repair only the protective cover 4 as appropriate.
