[Industrial applications]

 The present invention relates to a floor heating device that uses a floor heating panel placed on a floor surface for use.

[0002]

[Prior art]

 Conventionally, a floor heating panel has been used for a floor heating device installed and used on a floor surface, but this type of floor heating panel is disclosed in, for example, Japanese Utility Model Laid-Open No. 58-47016. The so-called heating tatami mats are used.

In this heating tatami mat, a heating element, a cushioning material, and a tatami mat, which generate heat when electricity is applied, are laminated on the surface of the tatami mat, and the tatami mat has an insulation board layer made of, for example, wood fiberboard on the back side. This insulation board is provided with grooves extending diagonally from the four corners to the intersections and corners, and a temperature controller connected to the heating element is embedded in the intersections. The power supply cord and the feed wiring cord connected to the commercial power source side drawn out from the temperature controller are housed in the respective groove portions.

Then, when a plurality of heating tatami mats are placed on the floor surface in a predetermined arrangement, the power feeding cord is a cord on the commercial power source side (a power cord connected to the controller body or an adjoining heating tatami wiring). Cable), the feed wiring cord is connected to the power feeding cord of the adjacent heating tatami mat, and the cord is used to connect multiple heating tatami mats from the controller body as a whole. Further, when the heating tatami mat is placed on the floor surface, the back surface of the tatami floor is in contact with the floor surface, and the cords are housed in the grooves between the tatami floor and the floor surface.

[0005]

[Problems to be solved by the device]

 In the heating tatami where the cord is wired between the back side of the tatami floor and the floor surface as in the above publication, in order to accommodate the cord, the insulation board on the back side of the tatami floor is grooved from the intersection to the corner. In addition to the necessity of applying the cord, the cord is housed in the groove provided from the intersection on the back surface of the tatami floor to the corner, so that the wiring direction of the cord is limited to the shape of the groove. This inconvenience is, for example, when the position of the controller main body is not on the corner of the heating tatami mat but on the side of the heating tatami mat, the power cord connecting the controller main body to the heating tatami mat. Inconvenience of having to run around the wiring in the room, or when the cord comes out of the groove when it is placed on the floor of the heating tatami mat, the insulation board made of wood fiberboard, etc. There is the inconvenience that the code is sandwiched between the floor and the floor, and the code is easily damaged.

The present invention has been made in view of the above circumstances, and provides a floor heating apparatus that does not require groove processing on the back surface of the floor heating panel and can arbitrarily connect a connection cord. That is the purpose.

[0007]

[Means for Solving the Problems]

 The present invention relates to a floor heating device in which a floor heating panel having a heating element is placed on a floor surface, and a connection cord connected to the heating element is wired between the back side of the floor heating panel and the floor surface. The floor heating panel is provided with a back member made of a material capable of accommodating the connection cord by compressively deforming a contact portion with the connection cord interposed between the floor heating panel and the floor surface. A connecting portion of the heating element for connecting the connecting cord is provided so as to face from a part of the above.

[0008]

[Action]

 In the present invention, the floor heating panel is placed on the floor surface while connecting the connection cord to the connection portion on the back surface of the floor heating panel and wiring the connection cord between the floor heating panel and the floor surface. When the floor heating panel is placed on the floor surface, the back surface member contacts the floor surface almost entirely, and the contact area of the back surface member that contacts the connection cord wired between the floor surface and the floor surface is compressed. It is deformed to form a groove portion that accommodates the connection cord. Therefore, it is not necessary to pre-groove the rear surface of the floor heating panel to accommodate the connection cord, and the connection cord can be wired at any position.

In this tatami floor 2, a back member 4 made of a foamed material of a plastic resin such as polystyrene is laminated on the entire back surface of an insulation board 3 made of, for example, a wood fiber board, which has a property of being less likely to be elastically restored during compression deformation. Has been formed. A rectangular recess 3a is formed in the central area on the front surface side of the insulation board 3.

On the surface of the tatami floor 2, the linear or planar heating element 5 is formed in the recess 3 a of the insulation board 3, and a flat plate having substantially the same shape as the heating element 5 and having a high thermal conductivity such as copper. The metal plate 6 is fitted and laminated, and the entire surface of the tatami floor 2 is covered, and the cushioning material 7 made of, for example, a non-woven fabric of polyester resin, the adhesive film 8, and the tatami mat 9 are sequentially laminated. Has been done.

On the surface of the tatami mat 9, an area line 10 indicating the embedded position of the heating element 5 is attached along a position slightly larger than the shape of the heating element 5, and a caution plate 11 is placed outside the area line 10. Is attached. The caution plate 11 has precautions such as cutting the outside of the area line 10 so as not to damage the heating element 5 when cutting the edge of the heating tatami mat 1, which will be described later.

Then, the tatami mat 12 is fixed to the side surface of the tatami floor 2 from the edges of the tatami mat on both long sides of the heating tatami mat 1 by sewing, so that the entire tatami mat is formed.

On the back surface of the heating tatami mat 1, an opening 4a is formed in a part of the back surface member 4, and a controller 13 electrically connected to the heating element 5 through the opening 4a is embedded. . This controller 13 is provided with a connecting portion 17 which faces the recess 14 and connects the connector 16 of the connecting cord 15. The control input from the main body of the controller (not shown) for controlling energization through the connecting cord 15 is provided. The energization of the heating element 5 is controlled based on the signal, and the temperature of the heating element 5 is detected and a detection signal is output to the controller body.

The heating tatami mat 1 is placed on the floor 18 in the arrangement shown in FIG. 4, for example.

As shown in FIG. 3, the connection cord 15 is configured by inserting two power source electric wires 21 and one signal electric wire 22 into a tube 23, and at the time of arrangement shown in FIG. A four-connector type that is sequentially connected to four heating tatami mats 1 and a two-connector type that is sequentially connected to two heating tatami mats 1 are used. The connection cord 15 of the 4-connector type includes a cord unit 24a from the controller body to the first heating tatami mat 1, a cord unit 24b to the second heating tatami mat 1, and a third heating mat 1 to the heating tatami mat 1. The connector 16 at the end of the branch cord 25a, which is provided with the cord unit 24c and is branched from the cord unit 24a, is connected to the connection part 17 of the first heating tatami mat 1 at the end of the branch cord 25b branched from the unit cord 24b. Is the connection part 17 of the second heating tatami mat 1, and the connector 16, 16 at the tip of the branch cords 25c and 25d branched from the code unit 24c is the connection part 17 of the third and fourth heating tatami mat 1, 17 connected respectively. In addition, the 2-connector type connection code 15 includes a cord unit 24e from the controller body to the fifth heating tatami mat 1 and branch connectors 25e and 25f that are branched from this cord unit 24e. It is connected to the connection parts 17, 17 of the fifth and sixth heating tatami mats 1, respectively.

Next, the operation of this embodiment will be described.

By the way, in general, tatami floors and the like are preliminarily formed in a large size, and the size of the tatami mat installation site in a room such as a house or condominium should be confirmed by the builder of the tatami mat installation. The edges of tatami floors are cut and tatami mats are stretched so that the tatami size is suitable for the size of the tatami installation. The same work is performed on the heating tatami mat 1.

When cutting the edge of the heating tatami mat 1, the operator checks the caution plate 11 displayed on the surface of the tatami mat 9 and cuts the outside of the area line 10. At this time, even if the vicinity of the heating element 5 is cut, the heating element 5 can be protected by the metal plate 6 laminated on the heating element 5.

Then, as shown in FIG. 4, each connector 16 of the 4-connector type and 2-connector type connecting cords 15 is connected to the connecting portion 17 of each heating tatami mat 1 to be housed in the recess 14, and A plurality of heating tatami mats 1 are placed on the floor surface 18 in the arrangement shown in the drawing while wiring 15 between the back surface of each heating tatami mat 1 and the floor surface 18. The base ends of the individual cords 24a and 24e of the connection cord 15 are connected to the controller main body that controls the energization of the heating element 5 of the heating tatami mat 1.

When the heating tatami mat 1 is placed on the floor surface 18, the back surface member 4 substantially entirely contacts the floor surface 18, and contacts the connection cord 15 wired between the floor surface 18 and the back surface member 4. The contact portion of the back surface member 4 is compressed and deformed to form a groove portion 4b for accommodating the connection cord 15.

Therefore, it is not necessary to make a groove on the back surface of the heating tatami 1 to accommodate the connection cord 15 in advance, and the connection cord 15 can be wired at an arbitrary position, especially connected to the main body of the controller. The cords 24a, 24e can be pulled out from any position of the heating tatami mat 1.

In addition, when the heating tatami 1 is cut off at its edge to change its size as described above and the connection cord 15 applicable to the large heating tatami 1 is applied to the small heating tatami 1, Although the length of the cord 15 is slightly extra, the extra amount can be absorbed by the wiring method of the wiring cord 15 that can be arbitrarily wired, and the connection cord 15 can be standardized.

When the heating operation is commanded by the controller body, the heating elements 5 of each heating tatami 1 are energized from the controller body, the heating elements 5 generate heat, and the heating tatami 1 rises to the set temperature. Be warmed.

In addition, the metal plate 6 laminated on the upper side of the heating element 5 can secure sufficient strength even in the case of the thin tatami floor 2, and has good thermal conductivity so that the warmth easily spreads over the entire surface. In addition, it is possible to prevent water spilled on the surface of the heating tatami 1 from reaching the heating element 5.
