Description

  The present invention relates to a floor heating apparatus that heats a room by heating a floor board.

As a conventional floor heating apparatus, for example, an apparatus including an electric heating mat disposed on a floor base plate and a floor plate laid on the electric heating mat is known (Patent Document 1). This electric heating mat has a heater sheet laminated on a flexible substrate and a small joist laminated on the heater sheet. The base material having flexibility is a thick nonwoven fabric or a soft synthetic resin foam. The heater sheet is a sheet-like material having permeability and a heater wire fixed in a meandering manner on one side.
JP 2003-166720 A

  However, in the conventional floor heating device, the floorboard is formed of a 9 mm thick plywood, a 9 mm thick medium fiberboard (MDF), or the like. Because the thermal conductivity of plywood and medium fiberboard that form the floorboard is not so high, the heat generated by the electrothermal mat is transferred to the floorboard, and the time to raise the room temperature, that is, the rise to the set temperature of heating Time tended to be long.

  The subject of this invention is that the rise time which heats up to the preset temperature of heating is short.

  In order to solve the above-described problems, the present invention provides an electric heating mat that is disposed on a floor base plate and can be electrically heated, a floor plate laid on the heating mat, and a control for electrically controlling the electric heating mat. In the floor heating apparatus comprising the apparatus, a layer on the back side of the floor board is replaced with a plate-like material having a specific gravity of 1.5 or more.

  By doing so, the heat generated in the electrothermal mat is transferred to the plate-like material. Since the plate material has a specific gravity of 1.5 or more, the thermal conductivity is large, and the heat generated in the electrothermal mat is transmitted to the plate material and further efficiently conducts heat in the plate material. Moreover, since the layer on the back surface side of the floorboard is replaced with a plate-like material, the thickness of the floorboard is smaller than when no plate-like material is provided, and the amount of heat passing through to the room side is increased. Therefore, the room is heated quickly, and the rise time for raising the temperature to the set temperature for heating is short.

  Next, each requirement constituting the present invention will be described in more detail. The floor heating apparatus of the present invention heats a floor board using electric energy and heats the upper space of the floor board.

  The plate material is not particularly limited as long as the specific gravity is 1.5 or more and the thermal conductivity is good. The plate material includes a very thin material such as a foil and a general plate thickness, and is selected according to a material to be used, a use condition, an application, and the like. When the specific gravity is less than 1.5, the thermal conductivity is small, so the amount of heat passing through the plate material is small, and the time for raising the temperature of the room is long. It is desirable that the plate-like material is hard and rigid from the viewpoint of load resistance. However, if the electric heating mat laid under the plate-like material has load resistance, it can be used with soft materials (or sheet-like materials). it can. Examples of plate materials include mortar plates, PC plates, gypsum boards, hard materials such as metal alloy plates such as iron, aluminum and copper, olefin resin materials, asphalt materials, and granular or powdery materials thereof. It is a soft material such as a composite material mixed with a heat conductive substance.

  The ratio of the thickness of the floor plate and the plate-like material is not particularly limited as long as the layer on the back side of the floor plate is replaced with a plate-like material having a specific gravity of 1.5 or more, but the total thickness of the floor plate and the plate-like material is The thickness is the same as or smaller than the thickness of the floor board when no material is provided. For example, if a conventional 9 mm floor plate is used, a floor plate having a thickness of 4 mm and a plate material having a thickness of 5 mm laminated on the back surface, a floor plate having a thickness of 7 mm, and a laminate 1 on the back surface are formed. And a plate-like material having a thickness of 5 mm. More preferably, the thickness of the plate-like material is larger than the thickness of the floor board. By doing so, more heat generated in the electrothermal mat can be passed to the room side.

  As a material for the floor board, it is preferable to use a wood system such as a plywood board, a wood fiber board (MDF, etc.), a wood chip board, and a single board laminated board. Since the floor board in this invention is thin compared with the conventional floor board, it is light and its workability is good. Moreover, since the floor board is thin, it is economical.

  The fixing between the floor board and the plate-like material is not particularly limited, but may be fixed by using an adhesive, a double-sided adhesive tape, or a nail in combination with these. As the adhesive in this case, it is preferable to use vinyl acetate, vinyl acetate / acrylic, ethylene / vinyl acetate, acrylic / ethylene, urethane, or the like.

  The electrothermal mat includes a base material having elasticity, an electric heater wire provided on or inside the base material, and a small joist provided on the base material surface. The electric heater wire is a wire that can generate heat electrically to convert electric energy into heat, and has a mechanical and physical pressure resistance that can withstand the compressive force from the floor plate and the plate-like material. The substrate is preferably a nonwoven fabric, a net-like sheet, paper, a perforated sheet, etc., having a thickness of several millimeters and having elasticity, and an electric heater wire is provided in a meandering manner on the surface or inside.

  Moreover, it is good for an electrothermal mat to have a heat dispersion sheet provided between a small joist and a base material, and to be overlaid on an electric heater wire. The heat dispersion sheet is preferably provided on the entire surface of the electrothermal mat. The thickness of the electric heating mat is a thickness in a state where the electric heating mat is sandwiched between the floor base plate and the floor plate, and the heat dispersion sheet and the base material are compressed, for example, 3 mm. This thickness is the sum of the thickness of the small joist, the thickness of the compressed heat dispersion sheet, and the thickness of the compressed base material.

  The small joists are provided as a plurality of elongated plates. The small joists are fixed to the floor base plate with screws, but since the base material has elasticity, the base material and the heat dispersion sheet located under the small joists are compressed, and the electric heating mat 3 including the small joists The thickness is approximately 3 mm. Moreover, the base material between small joists is formed so that a surface contact may be carried out to a floor board through a heat dispersion sheet.

  Further, the small joists are provided at positions that do not overlap the electric heater wires and are fixed on the base material or the heat dispersion sheet, but the shape is not particularly limited. In general, an elongated or strip-like plate or a rod-like material is used. Small joists are made of wood such as plywood, wood board, wood fiber board (MDF, etc.), wood chipboard, single board laminated board, etc., synthetic resin, metal board such as iron, copper, aluminum alloy, It can also be used for shapes. Further, the small joist is provided on the base material or the heat dispersion sheet so that the position where the small joist is fixed with a nail or a screw can be clearly understood, and the electric heater wire is not damaged by the nail or the screw.

  As described above, the electric heating mat serves to disperse the heat generated by the electric heater wire by having the heat dispersion sheet under the small joist, but the present invention further has the above described heat conduction on the small joist. By providing a plate-like material having good properties, heat is sufficiently supplied even at a position above the small joist, and the temperature of this portion is increased.

  The control device is connected to a terminal cover provided on the electrothermal mat via a cable. The control device is provided with a power cord for supplying power. Although the power cord may be used as it is connected to the control device, a plug (not shown) is attached to the power cord, and the power cord is temporarily used for the current test of the electric heating mat. When the test is completed, the power cord may be removed, and the power supply wiring may be provided between the control device and the distribution board. Electric control of the electric heating mat includes turning on / off the electric heating mat, strength of heating, prevention of overheating, prevention of electric leakage, and other heating reservations.

  The floor base plate supports a load applied to the floor plate via an electric heating mat or a peripheral mat. As the material of the floor base plate, for example, a wood system such as a plywood, a wood board, a wood fiber board (MDF or the like) is used. As a thickness of a floor base plate, what was selected from the range of 12-30 mm, for example is used. Furthermore, for example, polystyrene foam or the like may be provided as a heat insulating material between the joists supporting the floor base plate.

  According to the present invention, the layer on the back side of the conventional floor board is replaced with a plate-like material having a specific gravity of 1.5 or more, so that the heat generated in the electric heating mat is efficiently transferred to the floor board and stands up to the set temperature for heating. The time to raise can be shortened.

  Hereinafter, an embodiment of a floor heating apparatus according to the present invention will be described in detail with reference to the drawings. 1 to 12, the same or equivalent parts are denoted by the same reference numerals.

That is, the floor heating apparatus 1 includes the electric heating mats 3 and 4 disposed on the floor base plate 44 and the plate material 41 having a specific gravity of 1.5 or more provided on the electric heating mats 3 and 4.

  The floor heating device 1 further includes a floor plate 36 laid on the surface of the plate-like material 41 and a control device 50 that electrically controls the electric heating mats 3 and 4. The electric heating mats 3 and 4 are provided on this surface, and the electric heater wire 6 (shown in FIG. 3) that can be electrically heated and the small joists 11 to 16 provided at positions that do not overlap the electric heater wire 6 (FIG. 3). And the thickness T of the floor plate 36 is formed to be smaller by replacing the layer on the back side of the conventional floor plate with the plate-like material 41.

  A peripheral mat 31 that does not incorporate electric parts such as electric heater wires is provided on the floor base plate 44 between the four peripheral edges of the electric heating mats 3 and 4 and the walls of the room. The peripheral mat 31 has the same small joist 33 as the electric heating mats 3 and 4, and is formed to have substantially the same thickness as the electric heating mats 3 and 4 with a floor plate 36 laid thereon.

  The plate-like material 41 has a specific gravity of 1.5 or more and good thermal conductivity. However, the plate-like material 41 is not limited to a hard and rigid hard material but can be a soft material. Examples of the plate material 41 include mortar plates, PC plates, gypsum boards, hard materials such as metal alloy plates such as iron, aluminum, and copper, olefin resin-based materials, asphalt-based materials, and granular or powdery forms thereof. It is a soft material such as a composite material mixed with a heat conductive substance.

  The floor board 36 is made of wood such as plywood, wood fiber board (MDF, etc.), wood chipboard, and single board laminated board. In this case, the surface of the floor board 36 is a decorative surface. As the size of the floor plate 36, for example, a width of 303 mm × a length of 1818 mm × a thickness of 9 to 12 mm is selected.

  The control device 50 is connected to a terminal cover 20 provided on the electrothermal mats 3 and 4 via a cable 52. The control device 50 is provided with a power cord 53 for supplying power. The power cord 53 may be used as it is connected to the control device 50, but a plug (not shown) is attached to the power cord 53, and the power cord 53 is connected to the electric heating mats 3 and 4. The power cord 53 may be removed temporarily and the power supply wiring may be provided between the control device 50 and the distribution board when the energization test is completed. The electric control of the electric heating mats 3 and 4 includes turning on / off the electric heating mat, strength of heating, prevention of overheating, prevention of electric leakage, and other heating reservations.

  The floor base plate 44 is supported by joists 46, but supports the load applied to the floor plate 36 via the electric heating mats 3, 4 or the peripheral mat 31. As the material of the floor base plate 44, for example, a wood system such as plywood, wood board, wood fiber board (MDF, etc.) is used. As the thickness of the floor base plate 44, for example, a thickness selected from a range of 12 to 30 mm is used. Further, for example, a polystyrene foam or the like may be provided as the heat insulating material 48 between the joists supporting the floor base plate 44.

  FIG. 2 is a cross-sectional view taken along the line AA in FIG. The floor board 36 is formed by adhering a decorative material to the surface of the substrate on which the floor board 36 is formed, and a male fruit 38 or a female fruit 39 is formed along the longitudinal direction and the short direction. As the substrate of the floor board 36, a wood system such as a plywood board, a wood board, a wood fiber board (MDF or the like), a wood chip board, or a single board laminated board is used. As an example, the floor board 36 may be a board having a 4 mm-thick plywood substrate and an optional decorative material attached to the surface thereof.

  In Example 1, although the thickness of the floor board 36 is 4 mm, since the thickness of the plate-like material 41 laminated | stacked on the back surface is 5 mm, it corresponds to the thickness 9mm of the conventionally used floor board. Furthermore, since the thickness of the electrothermal mat 3 (including small joists) disposed under the plate-like material is set to 3 mm, it is apparent from the surface of the floor base plate 44 (not shown) to the surface of the floor plate 36. The thickness is 12 mm.

  In the first embodiment, the peripheral mat 31 is arranged in a frame shape on the floor base plate 44 so as to surround the electric heating mat 3 (and the electric heating mat 4). By setting the thickness of the peripheral mat 31 to 3 mm, the plate-like material 41 applied on the electric heating mats 3 and 4 and the peripheral mat 31 becomes flat, and the surface of the floor plate 36 laid thereon also becomes flat. . Since the electric heating mat 4 and the peripheral mat 31 provided around this, the electric heating mat 4 and the plate-like material 41 laid on the peripheral mat 31 and the floor plate 36 have the same structure as the electric heating mat 3, The description is omitted.

  FIG. 3 is a plan view of the electric heating mat shown in FIG. The small joists provided on the electric heating mat 3 and the small joists provided on the electric heating mat 4 have a substantially point-symmetrical positional relationship. The small joists 11 to 16 are provided in parallel with each other at an appropriate interval and in a staggered manner in the longitudinal direction. Furthermore, the electric heating mats 3 and 4 have a common terminal cover 20 in which terminals of the electric heater wires 6 are gathered. Further, it is preferable to provide a heat sensitive wire 7 (or a sensor wire, shown in FIG. 4) in the vicinity of the electric heater wire 6. The terminals of the electric heater wire 6 and the heat sensitive wire 7 are connected to the cable 52 (FIG. 1) at the position of the terminal cover 20. In addition, by providing the heat sensitive wire 7, the temperature of the floor board 36 is controlled and overheating is prevented.

  4 is a cross-sectional view taken along line BB in FIG. The floor heating device 1 includes an electric heating mat 3 laid on a floor base plate 44, a plate material 41 provided on the electric heating mat 3, and a floor plate 36 laid on the surface of the plate material 41. . The electrothermal mat 3 includes a base material 9 having elasticity, an electric heater wire 6 and a heat sensitive wire 7 provided on the surface, and a heat dispersion sheet provided on the base material 9, the electric heater wire 6 and the heat sensitive wire 7. 23 and an elongated small joist 15 provided on the heat dispersion sheet 23.

This thickness is equal to the sum of the thickness of the small joist 15, the thickness of the compressed heat dispersion sheet 23, and the thickness of the compressed base material 9.

  The substrate 9 is elastic such as a nonwoven fabric, a net-like sheet, paper, a perforated sheet, etc., having a thickness of several millimeters, and the electric heater wire 6 is provided in a meandering manner on the surface or inside thereof. The small joist 15 is provided as a plurality of elongated plates. The material of the small joist 15 uses a wood system such as a plywood, a wood board, a wood fiber board (MDF, etc.), a wood cutting board, a single board laminated board, and is fixed to the floor base board 44 with screws 18. Since the material 9 has elasticity, the base material 9 and the heat dispersion sheet 23 located under the small joist 15 are compressed, and the thickness of the electrothermal mat 3 including the small joist 15 is approximately 3 mm. Further, the base material 9 between the small joists is formed so as to be in surface contact with the plate-like material 41 through the heat dispersion sheet 23.

  When the floor board 36 is fixed using a nail, the floor plate 36 is disposed at the position of the small joist 15 of the electric heating mat 3 so that the seam is located. The material 9 is fixed to the floor base plate 44 with nails. Of course, you may use a nail and an adhesive or a nail and a double-sided adhesive tape together. When the floor board 36 is fixed to the plate-like material 41 with an adhesive or a double-sided adhesive tape without using nails, the seam of the floor board 36 does not necessarily have to be positioned on the small joist 15 and positions other than the small joist 15 are used. But it ’s okay.

  The electric heating mat 3 serves to disperse the heat generated by the electric heater wire 6 by having the heat dispersion sheet 23 under the small joist 15, and further, a plate-like material having good thermal conductivity on the small joist 15. By providing 41, heat is sufficiently supplied even at a position above the small joist 15 so that the temperature of this portion is increased. FIG. 4 shows the structure of the electric heating mat 3 at the position of the small joist 15; however, the structure and operation of the electric heating mat 3 at the other small joisting position and the electric heating mat 4 at the small joisting position conform to this. The description is omitted.

  FIG. 5 is a cross-sectional view of the heat dispersion sheet shown in FIG. The heat dispersion sheet 23 disperses the heat generated by the electric heater wire over the entire surface of the electrothermal mats 3 and 4, such as a nonwoven fabric such as a spunbond 25, a net having a certain degree of heat resistance, a surface of paper, or the like. A foil 24 having thermal conductivity and flexibility, such as a copper foil or an aluminum foil, is stuck between the sheets, or is laminated to have a laminated structure, and has some compressibility.

When furniture or the like is placed near the wall of the room R, the electric heating mats 3 and 4 are positioned so as not to be positioned under the furniture or the like.

  After the installation positions of the electric heating mats 3 and 4 and the control device 50 are determined, the position of the marking line 55 indicating the position of the center line of the electric heating mat on the floor base plate 44 and the position 27 of the electric heating mats 3 and 4 on the terminal cover side The inking line 56 indicating is indicated. Further, the hole 21 for placing the terminal cover 20 of the electrothermal mat is drilled in the floor base plate 44 at the intersection of the blacking line 55 and the blacking line 56.

  FIG. 7 is a perspective view showing a state in which the small joists of the electric heating mat are fixed to the floor base plate with screws. The electric heating mats 3 and 4 are arranged by aligning the center line 5, which is a contact portion between the electric heating mat 3 and the electric heating mat 4, with the inking line 55 and aligning the terminal cover side end 27 of the electric heating mats 3 and 4 with the inking line 56. To do.

  After the electric heating mats 3 and 4 are arranged on the floor base plate 44, the electric heating mats 3 and 4 are fixed to the floor base plate 44 at the small joists of the electric heating mats 3 and 4. In order to fix the electric heating mats 3 and 4 to the floor base plate 44, first, the two small joists 11 and 12 located on the center line 5 side of the electric heating mats 3 and 4 are fixed to the floor base plate 44 with screws 18. At this time, the small joists 11 and 12 are fixed sequentially with screws 18 from the end 27 on the terminal cover side of the small joists toward the other end.

  After the two small joists 11 and 12 are fixed, the small joists 13 and 14 at both ends of the electric heating mats 3 and 4 are fixed to the floor base plate 44 with screws 18. Also in this case, the small joists 13 and 14 are sequentially fixed by the screws 18 from the end 27 on the terminal cover side to the other end. Next, the remaining small joists 15 and 16 are fixed to the floor base plate 44 using screws, and the fixing of the electric heating mats 3 and 4 is completed.

  FIG. 8 is a perspective view of a state in which a peripheral mat is provided around the electric heating mat. After laying the electric heating mats 3, 4, the cable 52 extending from the terminal cover 20 of the electric heating mats 3, 4 is laid on the floor base plate 44 to the control device 50. At this stage, electric power is temporarily supplied to the electric heating mats 3 and 4, and an energization test is performed to determine whether the electric heating mats 3 and 4 generate heat.

  Next, a peripheral mat 31 is laid around the periphery between the four peripheral ends 28 of the electric heating mats 3 and 4 and the wall surface. A small joist 33 is provided on the peripheral mat 31. The small joists 33 provided on the peripheral mats may be provided at the same intervals as the small joists 11 to 16 of the electrothermal mats 3 and 4 as shown in this figure, but may be provided at different intervals (pitch). By providing the small joist 33 on the peripheral mat 31, the peripheral mat 31 has the same structure as the electrothermal mats 3 and 4, the surface of the plate-like material 41 provided thereon is flat, and the surface of the floor plate 36 is also uneven. It becomes a flat surface without any.

  In addition, in the floor heating apparatus 1 of Example 1, although the surrounding mat 31 is laid around the electric heating mats 3 and 4, this invention is not limited to this, The electric heating compressed with the floor board 36 stretched | stretched A peripheral panel formed of plywood having the same thickness as the mats 3 and 4 may be laid.

  The floor heating device 1 according to the first embodiment described above operates as follows. In FIG. 1, the heat generated in the electrothermal mats 3 and 4 is transferred to the plate material 41. Since the plate-like material 41 has a specific gravity of 1.5 or more, the thermal conductivity is large, and the heat generated in the electrothermal mats 3 and 4 is efficiently conducted through the plate-like material 41. Furthermore, since the thickness T of the floor board 36 laid on the surface of the plate material 41 is formed thin, the amount of heat passing from the plate material 41 to the room side is large. Therefore, the room is heated quickly, and the rise time for raising the temperature to the set temperature for heating is short.

Or you may provide on the left-right direction extension part and up-down direction extension part of the electrothermal mats 3 and 4. FIG.

  Since the floor heating apparatus 2 of Example 2 should just provide the plate-shaped material 41 only in required places, such as on the electrothermal mats 3 and 4, it can improve workability and economical efficiency. The structure and operation of the other parts of the floor heating device 2 of the second embodiment shown in FIGS. 10 to 12 are the same as those of the floor heating device 1 of the first embodiment shown in FIGS.
