  To install a floor heating system in a room, for example, laying a heating element such as an electric carpet or a sheet-like heating element, energizing the heating element, laying a finished floor panel on the heating element, and installing / wiring the controller Carpenter work that is done by carpenters and electric work that can only be done by qualified personnel are included, and these are often carried out in a complicated manner. It had to be done and was inefficient.

  Accordingly, an object of the present invention is to consistently perform a series of operations from laying an electric heating mat to floor finishing only in carpentry work in installation of a floor heating apparatus that requires various work including carpentry work and electrical work. An object of the present invention is to provide a floor heating apparatus having such a novel configuration.

  In order to achieve the above object, a floor heating apparatus according to the present invention includes an electric heating mat provided with electric heater wires in a serpentine shape, a heating floor plate provided on the electric heating mat, a controller for controlling the electric heating mat, and an electric heating mat. And a cable that electrically connects the controller and a power cord with a tip plug that supplies power for an energization test to the heating mat via the controller. It has a cable and a controller side cable, and these connectors can be directly connected to each other and can be connected via an extension cable prepared separately.

  The electric heating mat is formed by arranging electric heater wires in a meandering manner on an elastic mat. Furthermore, it is preferable to provide a heat sensitive wire in a meandering manner along the electric heater wire. By providing the heat sensitive wire, overheating of the electric heater wire can be prevented. The electric heater wires and the heat sensitive wires wired in a meandering manner in the mat enter and exit the wiring box provided in the electric heating mat. It is preferable that the electric heating mat is further provided with an elongated or strip-like thin plate (small joist) on the electric heating mat at a position where it does not overlap with the electric heater wire and the heat sensitive wire. Prevents direct action on the heat sensitive wire and protects the heater wire and the heat sensitive wire.

  The wiring box also serves as a switching means for electrically connecting the heater wire and the heat sensitive wire on the electrothermal mat side to a cable formed of a normal electric wiring material.

  The cable that connects the wiring box and the controller has an electric heating mat side cable and a controller side cable each having a connector at the tip, and these connectors can be directly connected to each other and are separately prepared extension cables. It can be connected via.

  The controller performs control such as turning on / off of the electric heating mat, strength of heating, selection of an overheated place, and prevention of overheating of the heater wire. In addition, a power cord that supplies power for the current test to the electric heating mat is pulled out from the controller, and a plug is provided at the tip of the power cord, so a carpenter who is not qualified for electrical work laid the electric heating mat. Later, an energization test can be performed by subsequently inserting the plug into a separately prepared construction outlet. A screwless terminal may be provided on the controller side to which the power cord is connected. In this way, after the carpenter conducts the energization test of the electrothermal mat, the power cord can be easily removed when the electrician performs the electrical wiring work, and the work efficiency is improved.

  According to the above configuration, since the detachable connector is provided on the cable for electrically connecting the electric heating mat and the controller, even a person who is not a qualified electrician can connect the electric heating mat and the controller with the cable. it can. Further, since the power cord drawn from the controller is provided with a plug, by connecting to the power source through this plug, even a person who is not a qualified electrician can perform an energization test of the electrothermal mat. Therefore, a series of work from laying the electric heating mat to finishing the floor can be performed consistently by carpentry work alone.

  The electric heating mat and the controller can be separated by removing the cable connector, so the electric heating mat is positioned on the base material and the cable is routed under the floor or along the groove provided on the back side of the floor board. Since the electric heating mat side cable can be electrically connected via the controller side cable and the connector, the wiring work is easy.

  Also, if you prepare an extension cable separately and connect the electric heat mat side cable and the controller side cable via this extension cable and connector, you can attach the controller to any place, Convenience is good.

  Further, when the electric heating mat or the controller fails, the device or part can be removed and repaired by disconnecting the failed cable from the connector.

  Hereinafter, an embodiment of a floor heating apparatus according to the present invention will be described with reference to the accompanying drawings.

  Referring to FIGS. 1 to 11, this floor heating apparatus includes an electric heating mat 1 in which a pair of electric heating mats 1 a and 1 b provided with electric heater wires in a meandering manner are provided symmetrically, and the electric heating mat. 1 is provided with a heating floor plate 2 laid on 1, a controller 3 that controls the electric heating mat 1, and cables 4 and 5 that electrically connect the electric heating mat 1 and the controller 3. A power cord 7 is pulled out from the controller 3, and a plug 8 is provided at the tip of the power cord 7. The power cord 7 is detachably connected to a screwless terminal provided in the controller 3 and can be easily removed when an electrician finally performs electric wiring work.

  The electric heating mat 1 (1a, 1b) has a non-woven fabric 11 having elasticity as a base material, and an electric heater wire 12 and a heat sensitive wire 13 are stuck on the non-woven fabric 11, and a laminate 14 is laminated thereon in contact therewith. (FIG. 8). An example of the laminated body 14 has a three-layer structure in which laminated aluminum sheets 14a and 14b formed of a nonwoven fabric or the like are laminated and bonded together with an aluminum foil 14c having thermal conductivity and flexibility interposed therebetween (see FIG. 9). The laminated body 14 is provided on the entire surface of the nonwoven fabric 11 via the heater wire 12 and the heat sensitive wire 13, and is used to disperse the heat generated by the heater wire 12 in a plane and efficiently transmit it to the floor plate 2 for heating. .

  A plurality of small joists 15 that are vertically long thin plates are bonded in parallel to the electric heating mat 1 (1a, 1b). The small joists 15 are elongated or strip-shaped, and are disposed between the laminate 14 provided on the surface of the electric heating mat 1 and the floor 3 for heating. As the material of the small joist 15, woody materials such as plywood, wood board, wood fiber board (MDF, etc.), wood chipboard, and single board laminate board can be used. Further, the small joists 15 are arranged so as not to overlap with the heater wires 12 and the heat sensitive wires 13, and are fixed to the base material 17 with wood screws (screws) 16 through the laminate 14 and the nonwoven fabric 11 (FIG. 8). In this case, since the nonwoven fabric 11 has elasticity, the nonwoven fabric 11 located under the small joist 15 is in a compressed state. The small joists 15 have a point-symmetrical positional relationship with respect to the center of the electric heating mat 1 and are arranged in a staggered manner as illustrated with reference to the edge of the electric heating mat 1. The material of the base material 17 uses a wood system such as plywood, wood board, wood fiber board (MDF, etc.), and its thickness is, for example, 15 mm. The base material 17 is laid on the joists 24, and a heat insulating material 25 is filled between the joists 24.

  The heater wire 12 of the electric heating mat 1 is attached in a meandering manner between the small joists 15 and 15 (FIG. 7). The heat sensitive wire 13 (not shown in FIG. 7) is provided in the vicinity of the small joist 15 and along the heater wire 12, but is arranged so as not to overlap the heater wire 12 (FIG. 8). The heat sensitive wire 13 functions to sense and prevent abnormal overheating caused by the heater wire 12.

  The floor plate 3 for heating is configured by sticking a decorative material on the surface of a base material, and a male fruit 20a (FIG. 4) and a female fruit 20b (FIG. 5) are formed along the longitudinal direction. Plywood, wood board, wood fiber board (MDF, etc.), wood chipboard, single board laminated board, etc., wood, styrene resin board, vinyl chloride resin board, reinforced plastic board, polystyrene foam resin board, urethane foam resin It consists of a synthetic resin system such as a board, or a composite laminated board of a wood system and a synthetic resin system. As a decorative material to be stuck on such a substrate, a natural veneer obtained by cutting natural wood, an artificial veneer, a nonwoven fabric, paper, a synthetic resin sheet, or the like can be used, and a sheet of flexible material. You may use what printed various patterns on. As a synthetic resin sheet used as a decorative material, for example, an olefin resin, a vinyl chloride resin, a polyester resin, an acrylic resin, or the like can be used. The thickness of the decorative material is determined in the range of 0.05 to 1 mm, for example.

  As an example, a decorative board obtained by sticking an optional decorative material as described above to a surface of a 9 mm thick plywood as a base material can be used as the heating floor board 3. A peripheral panel 10 made of plywood having the same thickness as the thickness of the electric heating mat 1 (3 mm in this embodiment) is applied in a frame shape on the base material 17 in a portion where the electric heating mat 1 is not applied. In this case, the peripheral floor boards 18a and 18b and the adjustment floor boards 19a and 19b, which will be described later, are all subjected to optional makeup by applying a cosmetic material on the surface of a 12 mm thick plywood as a base material. In both cases, the makeup is not shown. Since the decorative material is extremely thin, the thickness thereof is ignored, and the thickness of each floor board is assumed to be equal to the thickness of the plywood substrate.

  Outside the heating floor 2, 12 mm thick peripheral floors 18 a and 18 b are provided up to the wall position of the room via 12 mm thick adjusting floors 19 a and 19 b. Similar to the heating floor plate 2, male and female fruits are formed on the peripheral floor plates 18a and 18b and the adjustment floor plates 19a and 19b along their longitudinal directions (FIGS. 4 and 5).

  As described above, the thickness of the heating floor board 2 is 9 mm, but the total thickness of the small joist 15 and the electric heating mat 1 provided below (more strictly speaking, the nonwoven fabric 11 and the laminate below the small joist 15. 14 is overlapped and the total thickness when the nonwoven fabrics are arranged in a compressed state) is set to 3 mm. Therefore, the apparent thickness from the surface of the base material 17 to the surface of the floor board 2 for heating is set. Is 12 mm, which is the same as the thickness of the peripheral floor plates 18a, 18b and the adjustment floor plates 19a, 19b. Further, in this embodiment, a peripheral panel 10 (shaded portion in FIG. 6) made of plywood or the like in a frame shape is disposed on the base material 17 so as to surround the electrothermal mat 1, and the thickness of the peripheral panel 10 Is 3 mm, the total thickness of the peripheral panel 10 and the heating floor 2 is 12 mm, which is the same as the thickness of the peripheral floors 18a and 18b and the adjustment floors 19a and 19b. By providing the peripheral panel 10 in close contact with the four peripheral edges of the heating floor plate 2, the load resistance and caster resistance of the floor plate are improved.

  A male fruit 20a is formed on one of both side edges extending in the longitudinal direction of the floor board 2 for heating, and a female fruit 20b is formed on the other side edge. The male fruit 20a and the female fruit 20b are fitted to each other. It is possible to construct by connecting the floor plates 2 and 2 for heating through the horizontal connection.

  On one of the side edges extending in the longitudinal direction of the adjustment floor plate 19a, there is a female fruit 21b that fits the male fruit 20a in a state where the heating floor board 2 is placed on the electric heating mat 1 (and the peripheral panel 10). At the other side edge, a male fruit 21a that fits into a female fruit 22b formed on one side edge extending in the longitudinal direction of the peripheral floor plate 18a is formed (FIG. 4). Further, on one of the side edges extending in the longitudinal direction of the adjustment floor plate 19b, the male floor fitted with the female body 20b in a state in which the heating floor plate 2 is placed on the electric heating mat 1 (and the peripheral panel 10). 23a is formed, and a female fruit 23b is formed on the other side edge to fit a male fruit 22a formed on one side edge extending in the longitudinal direction of the peripheral floor board 18b (FIG. 5). Since the peripheral floor plates 18a and 18b and the adjustment floor plates 19a and 19b are all the same thickness, the male fruit 21a and the female fruit 22b for connecting them are the same in the thickness direction of the floor board. Although it is formed at the height position, the fruits 21b and 23a in the adjustment floor plates 19a and 19b are fitted to the fruits 20a and 20b in a state of being placed on the electric heating mat 1 (and the peripheral panel 10). It is formed at a very high position, and can be connected to the heating floor plate 2 having a different thickness.
