Description

TECHNICAL FIELD The present invention relates to a floor panel unit for floor heating and a floor heating system using the same.

<Prior Art and Problems Thereof> A method of arranging a large number of floor plate units that generate heat by energizing a heating circuit on a floor surface has been known as floor heating. The floor board unit for floor heating has a built-in heat generating circuit including a heating element and an overheat prevention device for preventing the heating element from overheating. One floor board unit has one heating circuit. Is equipped with.

When floor heating is performed using such a floor board unit for floor heating, as shown in FIG.
In order to set the area C and the area C not to be executed, the floor board units 10 had to be aligned vertically and horizontally. Therefore, the joints of the floorboard unit 10 are aligned in a straight line in the vertical and horizontal directions, and there is a problem that the joints are conspicuous and the appearance is inferior.

In order to avoid such a problem, as shown in FIG. 5, it is conceivable to lay out the floorboard units 10 for heating in a zigzag pattern to make the joints inconspicuous. In this case, the joint is less noticeable and is preferable in appearance, but on the other hand, when trying to secure a desired floor heating area H, since one floor plate unit 10 is equipped with only one heating circuit,
A portion h1 (shown by diagonal lines in the figure) protruding from the desired floor heating area H is also unnecessarily heated, and there is a problem that electricity is wasted.

Further, in one floor panel unit 10, the set temperature may be partially exceeded by laying a cushion or the like. In this case, since the overheat prevention device operates and the heating of the entire floorboard unit 10 is stopped, there is a problem that a low temperature portion is generated.

It is an object of the present invention to heat only a desired area even when laid in a zigzag pattern, and when the temperature exceeds a preset temperature, it is possible to stop energizing only that portion for floor heating. To provide a floor panel unit and a floor heating system using the floor panel unit.

<Means for Solving the Problems> In order to achieve the above object, a floor heating system using a floor heating floor plate unit of the present invention includes a heating element and an overheat prevention device for preventing overheating of the heating element. A floorboard unit for floor heating, in which a plurality of heat generating circuits each including and are electrically isolated from each other are arranged in each of the sections, which are sectioned at predetermined intervals along the longitudinal direction of the long floorboard. Are laid in a zigzag pattern by displacing the above sections so that the end surfaces on the short side of adjacent floor board units are not aligned in a straight line, and each heating circuit serves as an energizing means capable of restricting energization to a predetermined heating circuit. It is characterized by being connected.

<Operation> According to the floor heating system using the floor plate unit for floor heating having the above configuration, a plurality of heat generating circuits electrically independent from each other are provided in one floor plate unit at predetermined intervals along the longitudinal direction of the floor plate. Since the blocks are arranged for each of the sections, it is possible to set a portion to be heated and a portion to be not heated in each floor plate unit.

Further, according to the floor heating system having the above-described configuration, even though the floor board units are arranged in a zigzag manner, the energizing means regulates the energization of the heating circuit in the section protruding from the predetermined area, thereby providing a predetermined Only the area can be heated. In addition, since the floorboard units are laid out in a staggered pattern with a shift corresponding to the division of the heat generating circuit, the above-mentioned predetermined region can be divided by the heat generating circuits linearly arranged.

<Example> Hereinafter, the present invention will be described in detail with reference to the accompanying drawings illustrating an example.

FIG. 1 is a plan view of a floor board unit 1 for floor heating showing an embodiment of the present invention.

In the floorboard unit 1, two heating circuits 2, 2 electrically independent of each other are provided between a long bottom floorboard 6 and a long top floorboard 6 made of a wooden board such as plywood. It is arranged in each of the sections A divided into two along the longitudinal direction of the floor plate 6.

The floorboard unit 1 usually has a size of about 1818 m × 303 mm in consideration of the pitch between the joists. As the upper floor plate 6 and the lower floor plate 6, various wood-based plate bodies such as a single plate, particle board, hard board, and plywood can be used, and those having various thicknesses are appropriately used according to the purpose.

Each of the heating circuits 2 includes a sheet heating element 3 and an overheat prevention device 4 that prevents the sheet heating element 3 from overheating.
In the sheet heating element 3, conductive tapes are arranged alternately or at required intervals with respect to the non-conductive tapes in the longitudinal direction or the weft direction, and in the direction intersecting the conductive tapes and the non-conductive tapes. A non-conductive tape is arranged and woven into a plain weave structure. The planar heating element 3 is provided with electrode strips at regular intervals in a direction intersecting with the conductive tape. The conductive tape is connected between the electrode strips.

In addition, a plurality of sets of overheat preventing devices 4 including thermostats 4a and thermal fuses 4b are provided on the lower surface of the sheet heating element 3, and the sheet heating element 3 is operated by operating the overheating prevention device 4. Prevents heating above the set temperature.

FIG. 3 is a plan view showing a floor heating system using the floor board unit 1.

In this floor heating system, the floorboard units 1 are laid in a zigzag pattern by shifting the floorboard units 1 adjacent to each other in the longitudinal direction of the floorboard 6 by the amount of section A so that the end surfaces on the short sides are not aligned linearly. And each floorboard unit 1
The heating circuits 2 are connected to the energizing means 5. The energizing means 5 can selectively energize the entire area where the floorboard unit 1 is laid and energize only the area H where heating is performed. That is, the energizing means 5 energizes all the heat generating circuits 2 of each floorboard unit 1 arranged in the area C where the whole is not heated, and the floorboard unit 1 extending over both the area C and the area H. Among them, by restricting the energization of the heating circuit 2 in the section A (see the shaded portions c2, c3, c4) protruding from the area H, only the area H to be heated can be heated without excess or deficiency.

According to the above heating system, it is possible to heat only the desired area, although the floorboard units 1 are laid in a zigzag manner to enhance the appearance. Also, one on one floorboard unit 1
Even when a cushion or the like is laid on a portion corresponding to one heating circuit 2, even if only a certain part has reached a set temperature or more, electricity is supplied to the heating circuit 2 in the portion where the cushion is laid. Since the power is only cut off, the power supply to the other heat generating circuit 2 of the same floor plate unit 1 is continued without being cut off, so that it is possible to prevent a partial temperature decrease.

By selectively energizing the two heat generating circuits 2 of one floor plate unit 1, the heating setting area is not limited to a rectangle or a square, but can be set to a desired shape having an L shape or unevenness. . Therefore, by changing the design of the room, it is possible to adapt even when the arrangement of furniture changes and the setting of the heating area is desired to be changed.

In the above embodiment, the floorboard unit having two built-in heat generating circuits 2 is described, but the number of heat generating circuits is not limited to two, and three or more heat generating circuits are provided at predetermined intervals along the longitudinal direction of the floor board. It may be arranged in each divided section.

Further, although the sheet heating element 3 is shown as a woven material, any sheet having a high thermal conductivity may be used. For example, a sheet in which a carbon powder is dispersed in a plastic binder is applied to a sheet or cloth. A heat generating layer may be formed by fixing the electrode wire to the heat generating layer, or a heat generating wire made of a metal resistor may be arranged in a meandering manner on the interlining.

<Effects of the Invention> As described above, the floor heating system using the floorboard unit for floor heating according to the present invention can set a heated zone and a non-heated zone for one floorboard unit. Even if it is laid in a shape, only the desired area can be heated, which helps save energy. Further, when one section is overheated in one floor plate unit, it is possible to stop energizing only that section and continue heating in the other sections, so that temperature unevenness is unlikely to occur.

Further, according to the floor heating system of the present invention, since the floorboard units are laid out in a staggered pattern by shifting the sections of the heating circuit, the desired region can be partitioned by the heating circuits arranged in a straight line. As a result, it is possible to distribute the heating temperature in the room more evenly by arranging the above areas along each side of the floor surface that divides the room. Moreover, the appearance is beautiful, and it is possible to heat only the desired heating area, and to stop the energization to the section protruding from the area,
It helps save energy and is very economical.
