[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a floor heating panel in which connectors are connected to both ends of a power line connected to an electric heater built in a panel body, and one of the connectors is housed so as to be drawable from the panel body.
[0002]
[Prior art]
An example of this type of floor heating panel is shown in FIG. As shown in the figure, the floor heating panel 50 includes a panel main body 51 having a rectangular planar shape in which a plurality of pseudo grooves 51a extending in the longitudinal direction and a plurality of pseudo grooves 51b extending in the short direction are formed on the surface. A sheet heating element 52 having a self-temperature control characteristic is built in, and a pair of power lines 53 and one ground line 54 connected to the sheet heating element 52 extend in the short direction of the panel body 51. Connectors 55 and 56 are connected to both ends of the power supply line 53 and the ground line 54, respectively.
[0003]
As shown in FIG. 8A, one connector 55 is fixedly installed in a state of being accommodated in an accommodation recess 57 formed on one long side of the panel body 51, and the other connector 56 is As shown in FIGS. 5B and 5C, the panel main body 51 is housed in a housing recess 58 formed on the other long side so that the panel main body 51 can be pulled out.
[0004]
[Problems to be solved by the invention]
By the way, such a floor heating panel 50 has a restriction that it must be set to the same thickness as that of a normal floor board (usually about 12 mm), and the connectors 55 and 56 are usually about 8 mm thick. Therefore, if the housing recesses 57, 58 of the connectors 55, 56 are formed in the panel body 51 of the floor heating panel 50, the thickness of the panel body 51 in the portion where the housing recesses 57, 58 are formed is about 4 mm. The current situation is that it becomes thinner.
[0005]
Here, as shown in FIG. 8A, the housing recess 57 for housing the connector 55 on the fixed side may be set to a size that can just accommodate the connector 55. In the state in which the connector 55 is housed and fixedly installed, there is almost no space in the housing recess 57, and a load can be received by the housed connector 55. Therefore, in the portion where the housing recess 57 is formed. Even if the thickness of the panel body 51 is reduced, there is no particular problem.
[0006]
However, as described above, the housing recess 58 for housing the movable-side connector 56 must accommodate the power supply line 53 and the ground wire 54 in addition to the connector 56, so that it is intended to be housed. The width and depth of the connector 56 must be set larger than those of the connector 56. As shown in FIG. 8C and FIG. A space will be formed.
[0007]
In particular, as shown in FIGS. 7 and 9, when the housing recess 58 of the movable connector 56 is formed immediately below or in the vicinity of the pseudo groove 51b formed in the panel body 51, the thickness of the vicinity of the pseudo groove 51b is increased. When the impact load is applied to the portion where the accommodation recess 58 is formed in the state where the floor heating panel 50 having such a structure is laid, the pseudo groove 51b is cracked, The panel body 51 may be destroyed.
[0008]
Accordingly, an object of the present invention is to provide a floor heating panel in which a panel main body is not destroyed even when an impact load is applied to a portion in which a housing recess for housing a connector is removably received.
[0009]
[Means for solving the problems and effects thereof]
In order to solve the above-mentioned problem, the invention according to claim 1 is directed to a panel main body having a pseudo groove extending in the short direction formed on a surface thereof, an electric heater built in the panel main body, and a wire connected to the electric heater. The panel main body that accommodates the power supply line that crosses the panel main body in a state in which the panel main body is connected, the connectors respectively connected to both ends of the power supply line, and the one connector that can be pulled out from one long side of the panel main body. In the floor heating panel provided with a housing recess formed on the back surface side of the panel body, the floor heating panel is removed from the vicinity of the pseudo groove formed in the panel body, and at a reference position at a pitch of 303 mm from the longitudinal end of the panel body. The housing recess is formed so as to be out of the region within 25 mm on the left and right .
[0010]
In the floor heating panel configured as described above, the housing recess is formed so as to be removed from the vicinity of the pseudo groove formed in the panel body, so that the thickness of the pseudo groove portion and the vicinity of the pseudo groove in the panel body is extremely large. It never gets smaller. Therefore, even if an impact load is applied to the portion where the housing recess is formed in the state where the floor heating panel is laid, the pseudo groove portion is hardly cracked, and the panel body can be effectively prevented from being broken.
[0011]
In addition, when laying the floor heating panel by the joist method, the joists with a width of 45 mm are normally arranged at a pitch of 303 mm, so when dropping the floor heating panel under the floor to connect the power line to the power source, The power line is less likely to hit the joists, and the workability of laying the floor heating panel is improved.
[0012]
In particular, as in the floor heating panel according to claim 2, if the housing recess is formed so as to be out of a region within 10 mm on the left and right sides of the pseudo groove formed in the panel main body, The strength of the groove portion and the vicinity of the pseudo groove is increased, and it is possible to reliably prevent the panel body from being broken due to the impact load applied to the portion where the housing recess is formed.
[0013]
Moreover, like the floor heating panel of Claim 3 , if the reinforcement board is fixed to the upper surface of the said accommodation recessed part, the effect that the intensity | strength of the panel main body in the part in which the accommodation recessed part is formed will improve further. is there.
[0014]

The planar heating element 20 is laminated with a synthetic resin film in a state in which a soaking sheet (not shown) having a good thermal conductivity made of an aluminum foil or the like is attached to the surface side in advance. .
[0018]
As shown in FIG. 3A, the planar heating element 20 is accommodated in a heating element accommodating recess 11b formed in the panel base 11 as shown in FIG. The back plates 16a and 16b are fitted into 11a and fixed to the panel base 11 to be held in the heating element housing recess 11b. The back plates 16a and 16b are provided so as to cover the heat generating portion 21 of the planar heat generating element 20 accommodated in the heat generating element accommodating recess 11b, and are non-heat generating in which the power supply line 30a and the ground line 30b are provided. The part is opened so that the power supply line 30a and the ground line 30b are exposed.
[0019]
Further, as shown in FIG. 2 (a), connector receiving recesses 14a and 14b for receiving the connectors 40a and 40b are formed on the back side of the panel base material 11, respectively, as shown in FIG. A shallow connection groove 15 connecting the connector receiving recesses 14a and 14b is formed in a portion where the power line 30a and the ground line 30b cross. One connector 40a is fixedly installed in a state of being accommodated in the connector accommodating recess 14a, while the other connector 40b is accommodated in a connector that can be pulled out from the panel base 11 as shown in FIG. It is accommodated in the recess 14b.
[0020]
As shown in FIGS. 2 (a), 4 (b) and 4 (c), the connector receiving recess 14b for receiving the connector 40b from the panel base 11 is removably provided on the top surface thereof. Is fixed, and the upper surface of the connector receiving recess 14 b is completely covered by the reinforcing plate 17. The reinforcing plate 17 is made of anodized aluminum (insulated) and, as shown in FIG. 6, is hung from a main body portion 17a covering the upper surface of the housing recess 14b and from both side edges of the main body portion 17a. It is comprised from the drooping parts 17b and 17c.
[0021]
The connector housing recess 14b must be housed together with the connector 40b in a state in which a part of the power supply line 30a and the ground wire 30b are bent, as shown in FIG. 2 (a), FIG. 4 (c) and FIG. The width and depth of the connector receiving recess 14a are larger than those of the connector receiving recess 14a, and as shown in FIG. 1, the position is 10 mm or more away from the pseudo groove 12b, and the pitch is 303 mm from the end of the panel body 10 in the longitudinal direction. It is formed at a position that deviates from a region within 25 mm on the left and right of the reference position. Accordingly, the connector receiving recess 14a is also formed at a position that is out of the region within 25 mm on the left and right of the reference position with a pitch of 303 mm from the end in the longitudinal direction of the panel body 10.
[0022]
As described above, the floor heating panel 1 has the connector receiving recess 14b whose width and depth are set to be large to accommodate the movable connector 40b, and the pseudo groove 12b extending in the short direction of the panel body 10. Since it is formed at a distance of 10 mm or more from the formation position, the thickness of the pseudo-groove 12b portion in the panel base material 11 and the vicinity of the pseudo-groove 12b is not extremely reduced, and the strength of the panel base material 11 is partly remarkable. There is no decline. Therefore, even if an impact load is applied to the portion where the connector receiving recess 14b is formed in the state where the floor heating panel 1 is laid, the pseudo-groove 12b portion is not easily cracked, and the panel main body 10 is reliably destroyed. Can be prevented.
[0023]
In particular, in this floor heating panel 1, since the reinforcing plate 17 made of aluminum is fixed to the upper surface of the connector housing recess 14b, the strength of the panel body 10 at the portion where the connector housing recess 14b is formed is further improved.
[0024]
In addition, when laying floor boards and floor heating panels by the joist method, lay the floor boards and floor heating panels so that the ends in the longitudinal direction are positioned on the joists with a width of 45 mm arranged at a pitch of 303 mm. Therefore, the connector housing recesses 14a and 14b are separated from the region within 25 mm on the left and right of the reference position with a pitch of 303 mm from the longitudinal end of the panel body 10 as in the floor heating panel 1. If the floor heating panel 1 is laid, the possibility that the crossing portion of the power line 30a and the like will be on the joists becomes low. Therefore, when the floor heating panel 1 is laid, when the power line 30a or the like of the floor heating panel 1 is dropped below the floor in order to connect to the power source, the power line 30a or the like is less likely to hit the joist, and the floor heating panel 1 is laid. Improves.
