BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wooden heating floor material, and more particularly to a wooden heating floor material using a heater wire in a general household flooring.

[0002]

2. Description of the Related Art FIG. 8 shows a conventional wooden heating floor material for a general household with a rear floor material removed. As shown in FIG. 8, a frame 2 is provided on the back side peripheral edge of the wooden surface material 1 constituting the panel-shaped wooden heating floor material 50, and the heater wire 3, the heater power supply line 4, A connector 51 and a connector lead wire 52 are provided. The heater wire 3 is connected to one end of a heater power supply line 4, and the other end of the heater power supply line 4 is connected to a connector lead wire 52 via a connector 51. The heater wire 3 has a configuration in which the upper and lower portions thereof are sandwiched between heat equalizing materials (not shown). By providing a heat insulating material (not shown) below the heater wire 3, the wooden heating floor material 50 can be formed. Has formed.

[0003] At both ends in the longitudinal direction of the back surface of the wooden surface material 1,
A wiring storage section 33 of a certain space surrounded by a wooden frame is provided. The power supply line 4 for the heater, the connector 51, and the lead wire 52 for the connector are stored in the wiring storage section 33. The connector lead wire 52 supplies power to the heater wire 3 and also connects the heater wire 3 between each panel-like wooden flooring material.
The connector housing 52 is also used as a lead wire for connecting the connector lead wire 52 so that the connector lead wire 52 can be freely housed and wired from any direction of a cable outlet 53 provided horizontally, above, or below. Has a large space.

The connector lead wires 52 are subjected to terminal treatment for each single wire, and crimp terminals (not shown) are attached to the ends thereof, and these are connected by male and female fitting.

[0005]

However, according to the conventional wooden heating floor material 50, a large space is required in the wiring storage section 33, and the wiring storage section 33 requires the heater wire 3
Since it is not possible to install the panel, it is difficult for the heat from the heater wire 3 to be evenly transmitted to the wood-based surface material 1, and it is difficult for the user to feel the warmth at the boundary between the panels.

Further, in the wiring processing, the heater power supply line 4, the connector 51, and the connector lead wire 52 are simply housed in the wiring storage section 33 in a casual manner.
In many cases, the wiring members such as the connector lead wires 52 are entangled or overlapped in the wiring storage portion 33. As a result, these wiring members are often deformed, and these insulators are often damaged. In addition, there is a problem in practical use such as an increase in the thickness due to the overlapping of the wiring members and the generation of unevenness on the surface of the floor panel.

Also, since the cable outlet 53, which is the insertion portion of the connector lead wire 52, is formed on the back surface of the wooden surface material 1, the cable outlet 53 is connected when the wooden heating floor material 50 is connected. The connection work is difficult because the connection lead 53 is difficult to see, and if the connector lead 52 is lengthened to facilitate the connection, the connector lead 52
Is difficult to store in the wiring storage unit 33.

Accordingly, an object of the present invention is to provide a wooden heating floor material in which wiring materials are housed in a narrow space in an orderly manner, and a uniform temperature can be felt at any part of the wooden surface material.

Another object of the present invention is to provide a wooden heating floor material which has good handleability of a connector lead wire and is easy to connect.

[0010]
