DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The invention of this application is intended to improve the workability of an automatic wiring production line, secure a heating temperature at a panel joint, improve the efficiency of a caulking work, by the above features.
This makes it possible to optimize the temperature uniformity of the panel and the performance of preventing excessive temperature rise. Therefore, examples will be shown below, and embodiments of the invention will be described in more detail.

[0009]

1 is a plan view of a plane portion of a panel body showing an embodiment of the present invention, and FIG. 2 is an enlarged plan view of a portion A in FIG. First, as exemplified in FIG. 1, in the floor heating panel of the present invention, the cord heater (2) as a heat generating portion has a basic pattern of wiring in the longitudinal direction of the panel body (1). That is, wiring is performed so as to form a linear pattern in the longitudinal direction up to near both ends of the panel body. At the same time, as is made possible by such a wiring pattern, the cord heater (2) also has a large outer wiring pattern near the periphery of the panel body (1). That is, in FIG. 1, the cord heater (2) crosses the center line (B) from the upper side to the lower side and from the lower side to the upper side with respect to the center line (B) of the panel body (1). An outer wiring pattern is formed near the periphery of the panel body (1).

The above-described linear wiring pattern in the longitudinal direction and the wiring pattern around the outside can not be formed by conventional manual work, and are suitable for mechanical automatic wiring. Wiring greatly improves productivity. Moreover, conventionally, a sufficient heating temperature could not be secured at the peripheral portion of the panel body (1), that is, at the joint between the plurality of panel bodies (1). Is sufficiently secured.

A caulking portion for connecting the cord heater (2) and the lead wire (3) is arranged on the panel body (1), and the work at the caulking portion is manual, but in the present invention, The work has been smooth. That is, as illustrated in FIG. 2 in which the portion A in FIG. 1 is enlarged, a wiring pattern having a shape (5) in which the code heater (2) is folded is formed in the caulking portion (4). A lead wire tolerance absorbing portion (6) for absorbing a tolerance caused by connection between the heater (2) and the lead wire (3);
It has a plane groove or a step shape.

After the caulking operation, the caulked portion (4), the cord heater (2) and the lead wire (3) are returned to the flat portion of the panel body (1). Wiring pattern and lead wire tolerance absorption part (6)
The task becomes extremely easy due to the presence of If these are not provided, wiring in a predetermined pattern becomes difficult due to a change in the length of the cord heater (2) or the lead wire (3) due to the connection caulking operation, and the connection reliability at the caulked portion (4) is impaired. However, there is no such concern in the present invention as described above.

The work in the caulking section (4) becomes easy,
Moreover, the connection reliability is improved, and the heating temperature can be stabilized. In addition, as exemplified in FIG. 1, in the floor heating panel of the present invention, the thermostat (7) is disposed at a substantially central portion of the panel body (1), that is, at the position of the center line (B), and required connection is made. Is recommended. The arrangement of the thermostat (7) improves the uniformity of the floor heating panel without impairing the speed of the automatic wiring as described above, and also ensures the overheating prevention performance corresponding to local heat insulation. Will be.

FIG. 3 shows the thermostat (7).
Is an example of a circuit in which is disposed. The arrangement of such thermostats (7) depends on the size of the panel body (1), but usually a plurality of thermostats are arranged as shown in FIG. This is to ensure heat uniformity and excessive temperature rise prevention performance over the entire plane of the panel body (1).

However, even if a plurality of seats, furniture and the like having high heat insulation are placed on the floor heating panel according to the living conditions of the occupants, depending on the living conditions of the residents. However, the concern that the heating temperature will rise excessively will not completely disappear. If the local temperature rise exceeds the heat-resistant temperature of the components of the panel body (1), the quality of the panel body (1) such as the insulation performance can be affected. In particular, when such a partial heat insulating region is located at an intermediate position where the two thermostats (7) are arranged, it is conceivable that the detection of the excessive temperature rise is not always optimal for the function of the thermostat (7).

Therefore, as an aspect of the present invention, a guideline is provided as to what the arrangement pitch of the plurality of thermostats (7) should be. That is, as illustrated in FIG. 4, the temperature distribution in the panel at the time when the maximum temperature of the local heat insulating portion of the panel body reaches the heat-resistant temperature of the panel body constituent member is measured, and the temperature distribution is measured at the OFF temperature position of the thermostat. The installation of a thermostat.

As a result, the number of thermostats to be arranged can be minimized, and the cost can be reduced. Furthermore, the present invention also provides a floor heating panel using a PTC heater instead of using the above thermostat. For example, in the case of a floor heating panel using the thermostat (7) illustrated in FIG. 1, for example, the installation width (W1) of the thermostat (7) and the pattern width (W2) of the cord heater (2) This is because it is conceivable that the heating temperature at the position where the thermostat (7) is disposed may be low, without the pitch being equal.

Therefore, as shown in FIG. 5, a PTC heater having a characteristic performance of controlling the current by increasing the resistance of the heater as the temperature rises and controlling the current rise as a result is used. As shown in FIG. 6, the PTC heater (8) is partially disposed in a part of the wiring by the code heater (2) as the heating element disposed on the panel body (1). By this PTC heater (8), it is possible to effectively prevent the temperature of the panel body from being excessively increased due to local heat insulation as well as to make the panel body uniform by heat generation.

The PTC heater (8) is, as shown in FIG.
Since the width dimension can be provided to some extent, it is possible to sufficiently cope with local heat insulation, and to improve the uniform heat performance of the panel body. FIG. 8 shows a PTC heater (8).
FIG. 6 shows a circuit in which is used. Of course, the invention of this application is not limited by the above examples. Various aspects are possible for the structure of the details.

[Detailed Description of the Invention] As described above in detail, according to the invention of this application, workability in an automatic wiring production line is improved, heating temperature is secured at a panel joint, and crimping work is made more efficient. In addition, it is possible to optimize the soaking properties of the panel and the performance of preventing excessive temperature rise.
