[0002]
[Prior art]
Conventionally, for floor heating panels, techniques described in Japanese Utility Model Laid-Open No. 1-82410, Japanese Patent Application Laid-Open No. 8-121790, Japanese Patent Application Laid-Open No. 2000-39159, and the like are known. Among them, in JP 2000-39159 A, an elastic locking portion for locking between joists is provided at the longitudinal side end of the floor heating panel, and the floor heating panel is temporarily supported and then attached and fixed. Shows how to do.
[0003]
On the other hand, in recent years, a heat storage board containing a heat storage agent has been proposed from the viewpoint of energy saving. This heat storage board temporarily stores the heat energy supplied from the heater in the heat storage agent and then gradually dissipates the heat. Therefore, if the heat storage board is integrated with the flooring to form a heat storage type floor heating panel, floor heating can be performed efficiently. . Fig.5 (a) is sectional drawing of the width direction of the thermal storage type floor heating panel which fixed the said well-known thermal storage board to the back surface of the flooring with the fixing bracket, FIG.5 (b) is the longitudinal direction side view. . As can be clearly seen from FIG. 5A, the heat storage board A includes a heat storage agent case 52 containing the heat storage agent 51 and a heater 53 attached to the lower surface of the heat storage agent case 52. The heat storage board A is held by a plurality of wood screws 56 on the back surface of the flooring 55 using a fixing metal 54, and is further inserted into a long side inserted between the flooring 55 and the longitudinal end of the heat storage board A. It is firmly fixed by the pressing metal 57 so as not to move up and down. Thus, the floor material 55 is panelized integrally with the heat storage board A, and constitutes a heat storage type floor heating panel.
[0004]
[Problems to be solved by the invention]
However, when the floor material 55 and the heat storage board A are integrated and fixed as described above, the following problems occur. That is, when the heat storage board A is heated by the heater 53 at the time of heat storage, since the heater 53 is mounted on the lower surface thereof, the lower surface side becomes hotter than the upper surface side, and a force that expands downward due to thermal stress occurs. Try to warp convexly.
[0005]
Therefore, in the conventional fixing method in which the floor material and the heat storage type floor heating panel are integrated, and the deformation of the heat storage board A due to the thermal stress is fixed by the fixing bracket 54 and the pressing bracket 57, when the above-described thermal stress is repeatedly applied, There is a problem that 56 is pulled out or the fixing bracket 54 is broken in some cases. The present invention has been made to solve such problems, and provides a heat storage type floor heating panel having an improved mounting structure for mounting the heat storage board A on the back surface of the flooring. Let that be the issue.
[0006]
[Means for Solving the Problems]
That is, according to the present invention, in a floor heating panel composed of a heat storage agent case containing a heat storage agent, a heat storage board composed of a heater mounted on the lower surface of the heat storage agent case, and a floor material, the heat storage agent case A rising wall is provided on the longitudinal side edge of the wall, and a mounting portion is projected horizontally and longitudinally from the upper end of the rising wall, and the heat storage board is floored by a support member through an insertion hole provided in the mounting portion. There is provided a regenerative floor heating panel that is suspended and supported on the back side of the material.
[0007]
With the above configuration, the heat storage board is suspended from the back surface of the flooring through a gap. Therefore, the heat storage board is substantially free even if heating by the heater and subsequent floor heating by heat dissipation are repeated. Can expand and contract. As a result, since the force applied to the support member and the mounting portion is relaxed, the problem that the support member comes off or the mounting portion is broken can be solved.
[0008]
Further, the heat storage type floor heating panel is provided with an insertion hole in a mounting portion protruding horizontally and along the longitudinal direction from the upper end of the rising wall of the heat storage agent case, and the support member that is loosely fitted to the insertion hole performs the above operation. It is preferable to have a structure in which the heat storage board is suspended from the back surface of the flooring. In this way, for the reason described above, the support member is loosely fitted even if a force that moves downward and moves horizontally is exerted due to the reason described above. Can be prevented.
[0009]
Furthermore, it is preferable that an elastic material is interposed between the mounting portion that is provided in a horizontal and longitudinal direction from the upper end of the rising wall of the heat storage agent case and the back surface of the floor material. By doing so, the heat storage board is firmly supported by the support member via the elastic material, and the vertical deformation that occurs when the heat expansion board bulges downward and warps is absorbed by the elastic material contracting. The As a result, there is no problem that the wood screws come off or the fixtures are destroyed even if heating by the heater and subsequent floor heating by heat radiation are repeated for a long period of time.
[0010]
The support member is preferably a wood screw. Since the flooring material is usually made of a wood-based material such as plywood or a mug board, the heat storage board is firmly attached to the back surface of the flooring material by screwing the wood screw through the insertion hole. Can be supported by hanging.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a cross-sectional view in the width direction of a heat storage type floor heating panel according to the present invention. The heat storage board A is composed of a heat storage agent case 2 containing the heat storage agent 1 in a sealed state and a heater 3 attached to the lower surface of the heat storage agent case 2. The heat storage board A is usually integrally formed of polypropylene, and a planar heater is preferably used as the heater 3, and is attached to the lower surface of the heat storage agent case 2 by adhesion, other mechanical methods, or the like. .
[0012]
When power is supplied to the heater 3 (the power supply wiring, connectors, and the like are not shown), the heat storage agent 1 that is normally solid at room temperature is heated and melted into a liquid. When the power supply is continued and the temperature of the heat storage agent 1 reaches the upper limit set temperature, the power supply to the heater 3 is stopped, and the heat storage agent 1 gradually dissipates the latent heat of melting and returns to a solid while heating the floor. On the other hand, when the temperature of the heat storage agent 1 that has returned to solid due to a decrease in temperature due to heat dissipation reaches the lower limit set temperature, the power supply to the heater 3 is started again and is heated and melted. The power supply to the heater 3 and the power supply stop are performed using a commonly used temperature control device such as a thermostat. The heat storage agent is not particularly limited as long as it is a substance that melts by heating and releases latent heat by cooling. For example, solid paraffin is used.
[0013]
As described above, after the thermal energy supplied from the heater 3 is once stored in the thermal storage agent, the thermal storage board A that is gradually released from heat is easily panelized with the flooring 5 and is excellent in energy saving. In addition, it provides a regenerative floor heating panel with excellent workability. As can be clearly understood from FIG. 1, in the heat storage type floor heating panel of the present invention, the heat storage board A is supported by a wood screw 6 to be suspended from the back surface of the flooring 5 through the gap 4. This wood screw 6 is inserted through an insertion hole 8 provided in a mounting portion 7 provided in a horizontal and longitudinal direction from the upper end of the rising wall of the heat storage agent case 2, and is firmly screwed to the back surface of the flooring 5. The Further, an aluminum foil 9 as a soaking plate is attached to the back surface of the flooring 5, and a portion surrounded by the rising wall of the heat storage agent case 2 forms a space 10. The heat storage type floor heating panel according to the present invention configured as described above repeats heating by the heater 3 and then floor heating by heat radiation, and the heat storage board A is free to expand downward even when used for a long period of time. Therefore, there is no problem that the wood screw 6 comes off or the mounting portion 7 is destroyed.
[0014]
The wood screw 6 is preferably loosely fitted into an insertion hole 8 formed in an oval shape. FIG. 2 (a) shows that a wood screw 6 is inserted into an insertion hole 8 provided in a mounting portion 7 that protrudes from the upper end of the rising wall of the heat storage agent case 2 containing the heat storage agent 1 horizontally and over the entire length in the longitudinal direction. It is a fragmentary perspective view when making it loose-fit. FIG. 2B shows that the wood screws 6 are inserted into the insertion holes 8 provided in the mounting portions 7 projecting from the upper end of the rising wall of the heat storage agent case 2 containing the heat storage agent 1 in a plurality of horizontal and longitudinal directions. It is a fragmentary perspective view when making it loose-fit. In this way, the heat storage board A is more preferable because it can freely expand downward and can expand freely in the lateral direction.
[0015]
Furthermore, it is preferable that the heat storage type floor heating panel of the present invention is provided with an elastic material 11 such as urethane or rubber in the gap 4 between the back surface of the floor material 5 and the heat storage board A and fixed with a wood screw 6. FIG. 3 shows a cross-sectional view in the width direction when the elastic material 11 is interposed. By interposing the elastic material 11 in this manner, the space 10 surrounded by the rising wall of the heat storage agent case 2 is sealed, and heat from the heat storage agent 1 is prevented from escaping to the outside. An effect of preventing dust from entering the space 10 can be obtained. Note that a cushioning material such as polystyrene foam may be used instead of the elastic material.
[0016]
In FIG. 3, a heat dissipation control actuator 12 is provided in the space 10. The heat release control actuator 12 is formed into a bag shape by overlapping a rectangular upper sheet made of a soft plastic and a rectangular lower sheet and heat-sealing the peripheral edge, and an air inlet for feeding air 13 and an air discharge port (not shown) are provided. That is, the heat release control actuator 12 expands and contracts by taking in and out air, and operates to control the heat release amount from the heat storage agent 1 according to the degree.
[0017]
FIG. 4 shows a perspective view of a regenerative floor heating panel according to an embodiment of the present invention. In FIG. 4, the code | symbol 14 is a connector part which accommodates the connector for supplying with electricity to the thermal storage board A. In FIG. The heat storage type floor heating panel shown in FIG. 4 can be provided with a comfortable floor heating effect by usually laying a plurality of sheets on the floor or between the joists.
