Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a floor heating panel capable of uniformly heating the entire floor surface.

[0002]

2. Description of the Related Art Conventionally, so-called floor heating has been provided in which radiant heat generated by heating a floor warms a room more naturally. This floor heating is formed by laying on the floor surface a floor heating panel in which a heating element is arranged under a surface material to heat the floor. Although not shown, a surface material used for flooring or the like is formed on the surface of the long plate-shaped floor heating panel, and a heat generating member is formed under the surface material.

FIG. 5 is a schematic diagram showing a heat generating member of a conventional floor heating panel. The heat generating member 110 has a heating element 130 that generates heat due to electric resistance by passing electricity. Specifically, the heating element 130 is a wire-shaped wire heater wire 140. And, this wire heater wire 140 is arranged by folding back in a zigzag shape,
The interval between the wire heater wires 140 that were folded back and adjacent to each other was set to be constant.

Between the surface material and the heating element 130, the heat radiated from the wire heater wire 140 is not locally concentrated but dispersed and is uniformly transmitted to the front surface side of the panel. The soaking plate 120 was arranged. And
From both ends in the longitudinal direction of the heat generating member 110 of the floor heating panel,
A connection wire 160 was formed to connect with the adjacent floor heating panel 110. Although not shown, the connection wires 160 were pressure-bonded to each other by a superposition type pressure-bonding sleeve that overlaps the connection wires 160. Then, a cap-shaped member made of an insulating material is covered on the crimp-connected portion, and a vinyl tape is wound on the cap-shaped portion to perform insulation treatment. And the insulation-treated part is
The floor heating panel 110 was placed in the opening at the end in the longitudinal direction.

[0005]

However, in the heat generating member 110 of the conventional floor heating panel described above, the soaking plate 120 and the heating element 130 are provided at the periphery of the floor heating panel 110 corresponding to the boundary between the floor heating panels 110. However, there is a problem in that the heating element 130 has a lower temperature than that of the central portion which is buried below since the heating element 130 is not buried below.

Further, since the connecting process between the connecting wires 160 is performed by a crimping sleeve, which is covered with a cap-like member made of an insulating material, and is further subjected to an insulating process with a vinyl tape, the end portions in the longitudinal direction of the floor heating panel 110. It is necessary to provide a space for accommodating them, and a portion where the heat equalizing plate 120 cannot be embedded is formed, and it is not possible to narrow the region where the temperature is lower than that in the central portion.

Therefore, the invention according to claim 1 has been made in view of the problems of the above-mentioned conventional technique, and the purpose thereof is to lower the temperature even at the boundary of the peripheral edge of the floor heating panel. Instead, it aims to provide a floor heating panel that can be heated uniformly. In addition to this, the invention according to claim 2 intends to provide a floor heating panel that uses a wire heater wire as a heating element and increases its distribution density at the periphery of the floor heating panel to make the surface temperature uniform. It is a thing.

In addition to the above, the invention according to claim 3 is to provide a floor heating panel which makes the surface temperature uniform at the boundary between the longitudinal end portions. In addition to this, the invention as set forth in claim 4 is intended to provide a floor heating panel which makes the surface temperature uniform at the side edges in the longitudinal direction. In addition to this, the invention according to claim 5 further intends to provide a floor heating panel capable of extending the position of the soaking plate to the peripheral edge of the floor heating panel and making the surface temperature uniform even at the boundary. It is a thing.
