BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a floor heating panel. More specifically, the present invention relates to a floor heating panel that allows the failure state of the panel to be simply and easily determined and inspected in the event of a failure such as poor energization.

[Prior Art] A floor heating system in which a heater is built into the floor material has been known as one of the indoor heating methods for houses, etc. When installing the system, for example, a cross-sectional view of the system is shown in Fig. 4. Floor heating panels (A) have also been used. This floor heating panel (a) is, for example, a panel body approximately 15 mm thick, consisting of a decorative surface material (b) and a plywood base material with excellent heat insulation properties (c), and an electric heating panel. It has a built-in heater (D). In addition, there are metal heat equalizing plates (made of iron, etc.) on the top and bottom of the heater (D).
E) and a heat insulating layer (F) made of non-combustible material. The heat equalizing plate (E) evenly transmits the heat from the heater (D) to the surface material (A), while the insulation layer (F) prevents the heat from the heater (D) from escaping to the underfloor. It also protects the heater (d) itself. In addition, the heater (
A safety device (g) consisting of, for example, an overtemperature prevention switch or a thermal fuse is connected to (d).

[0003] In this way, the floor heating panel (A) is a laminated and integrated component that is necessary for floor heating installation, so it is possible to construct a floor heating system by simply laminating individual panels and installing the floor surface. It has the characteristic of being able to In addition, it is possible to partially lay out panels depending on the size, configuration, purpose, etc. of the room, and maintenance such as panel replacement and repair is easy.

[Problems to be Solved by the Invention] However, although the conventional floor heating panel shown in FIG. Even when it is sensed that a failure has occurred without the temperature rising, there is a drawback in that it is not possible to immediately determine whether the cause is a defect in the wiring or an abnormality inside the panel. Therefore, in the event of a failure,
Each time, we had to remove the floor heating panel (A) from the floor and check the wiring and the heater inside the panel (D). For this reason, there was an inconvenience in dealing with failures.

[0005] This invention was made in view of the above-mentioned circumstances, and aims to eliminate the drawbacks of conventional floor heating panels.
It is an object of the present invention to provide an improved floor heating panel that can simply and easily determine and inspect the failure state of the panel when a failure such as poor energization occurs.

[0006]

[Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a heat equalizing plate, a heater, a heat insulating material layer and a safety device inside a panel body consisting of a surface material and a base material. To provide a floor heating panel characterized in that the panel has a built-in energization indicator lamp for checking the energization state, and is provided with an energization cutoff switch and a measurement terminal for measuring an internal resistance value.

[0007]

[Example] Examples are shown below according to the attached drawings,
The floor heating panel of this invention will be explained in more detail. FIGS. 1 and 2 are perspective views showing an embodiment of the floor heating panel of the present invention from the front and back sides, respectively.

For example, as illustrated in FIGS. 1 and 2, the floor heating panel (1) of the present invention has a built-in energization indicator lamp (2) that indicates its energization state. A lid (3) can be attached to the top of the energization indicator lamp (2) in a removable or openable/closable manner. In addition, as shown in Figure 2, on the back side of this floor heating panel (1), a power disconnection switch (4) and a measurement terminal (5) for connecting a measuring device such as a tester are installed on the back side of the floor heating panel (1). Connection terminal (6) for interconnecting (1) with wires
It is arranged in the connection terminal block section (7) having a.

FIG. 3 shows an example of the circuit configuration of the floor heating panel of the present invention. As illustrated in this Figure 3,
The energization disconnection switch (4) illustrated in FIG.
Leave it in the N state. For example, in the floor heating panel of the present invention having the above configuration, when the surface temperature of the panel does not rise and it is sensed that a failure has occurred, first, as shown in FIG.
Open the lid (2) shown in and check whether the energization indicator lamp (2) is lit. Here, if the energization indicator lamp (2) is lit, it means that power is being supplied correctly, which means that the wiring connected to the connection terminal (6) for connecting the floor heating panel shown in is normal, and it is determined that there is an abnormality inside the panel. In this case, the floor heating panel (1) is removed from the floor and the energization cutoff switch (4) shown in FIG. 2 is turned OFF. After this, connect a measuring device such as a tester to the measurement terminal (5), measure the resistance value of the heater (8) inside the panel, the safety device (9) such as a thermostat, etc., and determine which part Check to see if there is a cause of the failure.

On the other hand, the energization indicator lamp (2) shown in FIG.
If the light is off, it is determined that power is not being supplied correctly and that there is a break in the wiring. As described above, in the floor heating panel of the present invention, by providing the energization indicator lamp (2) and the energization cutoff switch (4), the energization indicator lamp (2) can be turned off when a failure occurs.
It can be determined whether the fault is inside the panel or in the wiring by turning it on or off. Furthermore, if there is a failure inside the panel, it becomes possible to immediately inspect the inside. Maintenance, repair, etc. of the floor heating panel becomes simple and easy.

Of course, the invention is not limited to the above examples. It goes without saying that various aspects are possible with respect to details such as the arrangement positions and circuit configurations of the energization indicator lamp, energization disconnection switch, and measurement terminal.

As described above in detail, the present invention provides a new floor heating panel that can simply and easily determine and inspect the failure state of the panel when a failure such as a failure in energization occurs.
