Abstract

PURPOSE:To provide a low-cost floor heating panel including a reduced number of thermostats without deteriorating heat generation ability or safety by designing wiring density of a linear heater and disposition of the thermostats for preventing excessive temperature rise to achieve the purpose. CONSTITUTION:A linear heater 2 zig-zag disposed on a heat insulation material 1, plural thermostats 3 disposed between the linear heater 2, and a surface material are provided. Wiring density of the linear heater 2 around the thermostat 3 is set to be lower than wiring density at other ranges. Temperature rize at the time of heat insulation can thus be restricted using a reduced number of the thermostats compared to that in a conventional floor heating panel having a similar heat generation ability, thereby a low-cost floor heating panel can be provided.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating panel for a residential heating system.

[0002]

2. Description of the Related Art In a conventional floor heating panel of this type, as shown in FIG. 6, linear heaters 2 are arranged in a meandering pattern on a heat insulating material 1, and the linear heaters 2 are arranged between them. A plurality of thermostats 3 for preventing excessive temperature rise are arranged.

In the above structure, a uniform temperature distribution of the heating surface is obtained by making the wiring interval of the linear heater 2 constant, and the temperature of the heat retaining portion is improved when a warm cushion such as a cushion is placed. I try to prevent it from rising abnormally. Then, as shown in FIG. 3, this floor heating panel is laid on the floor of the house, and a floor finishing material such as wood flooring or carpet 4 is laid on it to perform floor heating.

[0004]

In such a conventional floor heating panel, the operating temperature of the thermostat for preventing excessive temperature rise should be made too low in order to obtain a sufficient warm feeling on the heating surface in normal use. I can't. On the other hand, in order to prevent the temperature of the heat insulation part from exceeding the heat resistance limit of the floor heating panel or floor finishing material even when the heat insulation material is placed just in the middle of the multiple thermostats, the size of the thermostat arrangement interval should be set to There is also a limit. That is, there is a problem that the minimum required number of thermostats is determined by the heat generation capacity per unit area of the floor heating panel and cannot be reduced below that.

The present invention solves the above-mentioned problems.
The objective is to provide an inexpensive floor heating panel with a small number of thermostats while maintaining the same heat generation capacity and safety.

[0006]

In order to achieve the above object, the floor heating panel of the present invention has a wiring density lower than that of the linear heater near the thermostat.

[0007]

According to the present invention, the number of thermostats is reduced as compared with the floor heating panel having the same heat generation capacity by wiring the linear heaters with a constant wiring density.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 1, 2, 3 and 4.

As shown in FIG. 1, reference numeral 2 denotes a linear heater which is installed on the heat insulating material 1 by wiring, and the wiring interval of the linear heater 2 is not constant but is provided in a high density portion 5 and a low density portion 6. ing. Further, four thermostats 3 are arranged in the high-density portion 5 to prevent an excessive temperature rise when a heat insulating material is placed.
These thermostats 3 are all at the same operating temperature, and the linear heater 2 and the plurality of thermostats 3 are shown in FIG.
They are electrically connected in series as shown in. Reference numeral 7 is a power supply introduction portion of the floor heating panel 8.

The operation of the above configuration will be described. As shown in FIG. 3, the floor heating panel 8 is laid on the floor of the house, and a floor finishing material for the carpet 4 is laid on the floor heating panel 8 to perform floor heating. If there is no heat insulating material on the floor, the thermostat 3 is not turned off and the linear heater 2 is energized. On the other hand, when a cushion or other good heat-retaining material is placed on the floor, the temperature of the heat-retained portion rises, but the temperature rise causes the thermostat 3 to turn off and the temperature of the heat-retaining portion to rise to the floor heating panel 8. The energization of the linear heater 2 is stopped so that the heat resistance limit of the carpet 4 is not exceeded.

Up to this point, it is the same as the conventional floor heating panel, but a case where a heat insulator is placed just in the middle of the thermostat 3 and another thermostat 3 will be described next. The temperature reached by the heat retaining section is determined by the heating capacity per unit area of the floor heating panel and the size of the heat retaining section. That is, if the heat insulation material is smaller than a certain size with respect to the heat resistance limit of the floor heating panel or floor finishing material, the heat resistance limit will not be reached, and if the heat insulation material is large, the thermostat 3 will be affected by the temperature.
Turns off to suppress the temperature.

In the floor heating panel of the present invention, since the wiring density of the linear heater 2 near the thermostat 3 is the high density portion 5 and the other area is the low density portion 6, the low density portion 6 is kept warm. If you do, the temperature reached will be low,
Therefore, it becomes possible to mount a large heat insulating material. This has the effect of widening the temperature rise detection range of the thermostat.

FIG. 4 is a characteristic diagram showing the respective temperature distributions of the surface of the floor heating panel 8 and the surface of the carpet 4 when the carpet 4 is applied on the floor heating panel described above.

It is generally said that when the wiring space of the linear heater is widened, temperature unevenness occurs on the surface of the floor heating panel, and a comfortable warm feeling cannot be obtained in use. However, according to experiments, As shown in FIG. 4, temperature unevenness is apparently generated on the surface of the floor heating panel 8, but the temperature unevenness is almost alleviated on the surface of the carpet 4 that is actually used, and there is no problem in use. Shows.

As described above, according to the floor heating panel of the embodiment of the present invention, since the wiring density of the linear heater in the vicinity of the thermostat is set to be lower than that of the other area, the conventional heater having the same heat generation capacity is used. Compared to floor heating panels, the number of thermostats can be reduced and the temperature rise during heat retention can be suppressed.

In this embodiment, the wiring density of the linear heater 2 is divided into two steps, that is, the high density portion 5 and the low density portion 6. However, as in the second embodiment shown in FIG. Even if the wiring density of the linear heater 2 is gradually lowered according to the distance from the thermostat, the same effect as that of the first embodiment can be obtained.

[0017]

As is apparent from the above embodiments, according to the present invention, the wiring density of the other regions is lower than the wiring density of the linear heater near the thermostat. It is possible to provide an inexpensive floor heating panel because it is possible to suppress the temperature rise during heat retention with a smaller number of thermostats than that of the floor heating panel.
