Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a planar heating device mounted on a floor of a house or the like.

[0002]

2. Description of the Related Art In floor heating in which a heating means is provided on a floor surface and is heated by radiant heat from the floor, the room air is not stirred and the temperature distribution in the vertical direction is good, so the room temperature is set relatively low. It has become popular because it is said that the air is hard to dry and it is ideal heating for head and foot heat. Among them, the panel on the joists used for the floor heating system of the full-scale construction type has a relatively large size of one sheet heating device,
Since it is firmly fixed to the surface of the base floor arranged on the floor of the building with screws or nails, it has load bearing strength itself and various floor finishing materials can be freely selected. In recent years, the demand has greatly increased, and a device for mounting a sheet heating device on the floor of a house while ensuring safety has been devised (for example, Japanese Patent Laid-Open No. 4-95377).

A conventional planar heating device will be described below. As shown in FIG. 4, the size of the substrate 3 is 1800 mm × 9
When 24 linear heaters 16 are evenly arranged at 00 mm, the space is 35 mm, which is too small as a space for screwing or nailing. Is a filled part that does not screw or nail, and in order to avoid damage to the heater 16 by screws and nails, holes for screws and nails are made in the peripheral part of the panel in advance, and the heater 16 is The non-existing portion is displayed on the surface plate 17, and screws and nails are used only in that portion.

[0004]

However, in the above-mentioned conventional configuration, the linear heaters 16 are arranged almost evenly on the entire surface of the substrate 3, and the portion without the heater 16 is limited to a very narrow range. Since the space for screws and nails is too small, the number of screws and nails that can be used to fix it to the floor during construction is limited, and it is difficult to firmly fix it to the floor part, and the heater is mistakenly used. There was a problem in that screws and nails were brought into contact with 16 to impair electrical insulation.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a planar heating device in which fixing screws and nailing can be accurately performed and electrical insulation is not impaired.

[0006]

In order to achieve this object, in a planar heating apparatus of the present invention, heaters are alternately arranged in a short pitch portion and a long pitch portion, and the short pitch portion and the long pitch portion of the heater are arranged. The surface plate is marked with a mark.

[0007]

In this structure, the arrangement of the heaters is integrated into the short pitch portion, a relatively large space can be secured in the long pitch portion, and fixing screws or nails can be used in the long pitch portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the size of the substrate 3 is 180.
When the surface plate 2 is an aluminum plate of 0 mm × 900 mm and the surface plate 2 is about 0.2 mm, the power density is 10 W / m due to the heat resistance of the insulation coating of the heater 1 in order to set the pitch of the heater 1 to 10 mm.
Must be: When the rated power of this planar heating device is 400 W, the total length of the heater 1 needs to be 40 m or more (400/10 = 40). Also, assuming that the effective wiring length in the longitudinal direction of the substrate 3 is 1.7 m, it is necessary to carry out wiring in 24 rows (40 ÷ 1.7 = 23.5). If the wiring of 24 rows is evenly arranged on the substrate 3 having a width of 900 mm, the pitch of the heater 1 becomes 37.5 mm (900 ÷ 24 = 37.5), and the width becomes about 35 mm when the wire diameter is subtracted. Therefore, as shown in FIG. 1, as an example of the wiring of the heater 1, the short pitch portion 6 has four wirings with the heater 1 having a pitch of 10 mm, and has six rows (24 ÷ 4).
= 6), the size of one row is 150 mm (900
÷ 6 = 150), and the occupied width of the four heaters 1 is 30
If you subtract mm (10 × 3 = 30), 120 mm (150-30
= 120), five long pitch portions 7 are formed. However, since the electric planar heating device has a plurality of thermostats 4 built-in according to the regulations, it becomes three when the space for two is drawn,
It is possible to secure a space where 5 screws and nails can be secured, including spaces at both ends. The short pitch portion 6 of the arrangement portion by the short pitch of the heater 1 and the arrangement portion of the thermostat 4 are filled in, and a display 8 such as printing is provided on the surface of the surface plate 2 so that the distinction from other portions can be clearly seen. Therefore, during the floor heating construction work, it is possible to firmly fix it to the floor portion by screwing or nailing the portion other than the filled portion of the display 8. Reference numeral 5 in the figure is a wiring box for power supply.

An embodiment in which the planar heating device of this embodiment is installed in a wooden house by a general conventional method will be described below.

As shown in FIG. 2, the sheet heating device 13 is laid on the joists 11 which are lined up with the heat insulating material 12 sandwiched therebetween, and the display 8 is screwed on the surface of the face plate 2. Also, the planar heating device 13 is fixed by driving the nail 14 into a portion of the nail that intersects the joist 11 in a possible space. Further, a floor finishing material 15 is laid on it.

FIG. 3 shows that when the sheet heating device 13 is laid and the floor finishing material 15 is attached, the pitch of the short pitch portions 6 of the heater 1 is 10 mm and the space of the long pitch portions 7 is 1
Adhesive surface of heater 1 and surface plate 2 when it is 20 mm
3 is a graph showing the respective temperature distributions of the surface of and the surface of the floor finish material 15. Generally, it is said that when the arrangement interval of the heaters 1 is widened, temperature unevenness occurs on the surface of the planar heating device 13, and a comfortable warm feeling cannot be obtained in use.
As is apparent from FIG. 3, temperature unevenness occurs on the surface of the planar heating device 13, but the floor finishing material 1 to be actually used 1
It can be seen that the temperature unevenness is almost alleviated on the surface of No. 5, and there is no problem in practical use. Therefore, it can be seen that there is no problem in terms of temperature if the space provided for using the screw or nail 14 at the time of actual construction is about 120 mm.

As described above, according to this embodiment, the heater 1 is alternately arranged with the short pitch portions 6 and the long pitch portions 7, and the short pitch portions 6 and the long pitch portions 7 are attached to each other. By displaying on the surface and adhering to the substrate 3 in sequence, fixing screws and nailing will not accidentally damage the electric insulation due to the heater 1 part, and it will be possible to firmly fix it to the floor. Become. Further, it is possible to prevent the temperature unevenness on the floor finishing material 15 from occurring.

A sheet-shaped heating element is used in which flat conductors having an arrangement similar to the arrangement of the heaters 1 coated with the above-mentioned insulating resin are sandwiched by a plurality of insulating materials located above and below. As for the planar heating device, there are 5 spaces other than the heater occupying space, and if 2 thermostat arrangement spaces are excluded, there will be 3 spaces, including 5 spaces for both screwing and nailing. In addition, by filling in the arrangement part of the heater with a short pitch and the arrangement part of the thermostat, and giving a display on the surface of the surface plate by means such as printing that clearly distinguishes it from other parts, It is possible to fix it to the floor part by screwing and nailing it to the part.

[0015]

As is apparent from the above description of the embodiments, the present invention has a display in which heaters are alternately arranged in short pitch portions and long pitch portions, and the short pitch portions and long pitch portions of the heater are distinguished from each other. With the configuration in which the surface plate is applied, it is possible to realize an excellent planar heating device that can accurately fix screws and nails for fixing and does not impair electrical insulation.
