Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor heating panel as a building material and heating equipment for a house. More specifically, the present invention relates to a new floor heating panel capable of easily connecting wiring between electric heaters of adjacent panels and mounting the panel itself.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, as one of the indoor heating systems, for example, a heater built-in type floor heating panel whose side view is illustrated in FIG. 4 is known. In the case of this floor heating panel (a), for example, a flat plate made of steel or the like is placed inside a panel body consisting of a surface layer material (a) with surface decoration and a base plywood (c) with excellent heat insulation. It has a built-in heating plate (d) and electric heater (e).

Since this floor heating panel (a) has a structure in which the members required for performing floor heating are laminated and integrated, by joining the individual panels to perform the floor surface, a floor of an arbitrary size can be obtained. The heating system can now be completed.

[0004]

[Problems to be solved by the device]

 However, in the case of such a conventional floor heating panel, wiring connection for supplying power to each heater (e) was not easy when laying a plurality of panels. Conventionally, for wiring between such panels, for example, as shown in FIGS. 5 (a) and 5 (b), a heater wire is provided in a notch groove (f) formed in a base material plywood (c) of a floor heating panel (a). A method has been adopted in which (K) and the ground wire (K) are pulled out and these are directly connected. However, in order to make such a wiring connection, it is necessary to turn over all the floor heating panels (A) and connect each wiring (K) (K) with, for example, crimping and caulking. It took a lot of effort and time. Further, as shown in FIG. 6, for example, a terminal block (K) is provided on the rear surface of the floor heating panel (A), and a socket (K) for the heater wire (K) and ground wire (K) is inserted into this. Therefore, there is also known a method of connecting wirings between floor heating panels (a). However, in this structure, although the connection work of each wiring (K) (K) is easy, the structure of the entire panel is that the terminal block (K) projects to the back surface of the panel (A). However, there is a drawback that the floor heating panel (a) cannot be directly attached to the base material. Moreover, even in the case of wiring connection using such a terminal block (K), the work is still done on the back side of the panel, and the problem of workability in panel construction is fundamentally solved. Was not.

Furthermore, in the case where a current is supplied from a common power source to a plurality of panels by the wiring connection method as described above, for example, as shown in FIG. ) Has been serially connected in series to form a current supply path from the distribution board (A) to each heater. However, in the case of this method, the panel mounting work was extremely complicated because the panels had to be arranged in order along the wiring connection direction. Furthermore, in the case of this method, as shown in the circuit diagram in Fig. 7 (b), the intensity of the current decays while it sequentially flows from the panel. In order to supply the current, a large amount of electric current (for example, 16 to 20 A) must be made to flow from the distribution board (A), and the panel that receives this electric current first has a thicker interior than other panels. Wiring (20 mm ² or more) had to be arranged. Therefore, for example, as shown in FIG. 8, a wiring method is also used in which the current from the distribution board (A) is supplied in parallel to each of the three floor heating panels (A) via the joint box (U). Has been. In this method, the wiring direction in each panel is the same as-, and the number of panels in which current flows in series is small, so the amount of current flowing between each panel does not change significantly. . However, all the lead wires (s) from each panel row had to be crimped and connected in the join box (c) one by one, which was extremely troublesome.

The present invention has been made in view of the circumstances as described above, and eliminates the drawbacks of the conventional floor heating panel wiring connection, and facilitates and accurately performs the wiring connection in panel construction. The purpose is to provide a new floor heating panel that can.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention has a drawer for wiring connection and a storable terminal portion on each of one side surface and end surface of a base plywood, and a terminal separate from these terminal portions. Provided is a floor heating panel characterized in that the terminal portion can be freely drawn and stored from the other side surface or end surface, and the terminal portion is provided inside a removable cover.

[0008]

[Action]

 When the floor heating panel of the present invention is used to connect and connect adjacent floor heating panels, first determine the wiring connection direction between each panel, and according to that, connect the terminal part whose direction can be changed to the end surface side. Or it can be pulled out and stored on the side. When connecting two panels in the longitudinal direction, the terminal parts drawn from the end faces of each other are joined, while in the lateral direction, the terminal parts on the side faces are joined.

For this reason, the wiring connection work between the panels is extremely easy, and moreover, all the panels can be mounted while facing up. Furthermore, since the current supply path can be set freely, wiring can be connected according to the panel construction order, and the circuit can be branched, so the current flowing through the internal wiring of each panel is uniform. Can be transformed.
