Description

[Detailed Description of the Invention] The present invention relates to an improvement of a floor heating device configured to heat a room from the floor surface.

Conventionally, in this type of floor heating system, a heat-generating panel is placed between the joists that support the flooring, and this heat-generating panel is supported by an appropriate support member, such as a tongue protruding from the joist or a floor plate formed on the underside of the joist. The structure is widely known.

The heating panel may be a planar electric heating element on the top surface of a hardboard, for example, an electric heating type with a meandering metal foil element interposed between two polymerized plastic films, or a hard foamed plastic board. Hot water types with hot water pipes embedded in the surface are used.

This type of floor heating system has heat generating panels disposed between the joists that support the flooring, so it has the advantage that the surface of the flooring can be kept flat without being affected by the arrangement of the heat generating panels.

However, in this type of floor heating system, if the flatness of the supporting members is poor, for example, the flatness of the floor plate (concrete, etc.) is defective, the plate-shaped plate stretched between the joists is not properly installed, or there are foreign objects on these supporting members. In some cases, a small gap is created between the heating panel and the flooring, which causes heat loss and deteriorates thermal efficiency.

The present invention improves these drawbacks.

This will be explained based on an embodiment shown in FIG.

The figure shows a case where a hot water type heat generating panel is used. In the figure, 1 indicates a joist, and 2 indicates a heat generating panel disposed between the joists 1.

As shown in FIG. 2, this heat generating panel 2 has a linear groove 4 formed in a heat insulating material 3, and a hot water pipe 5 is inserted into this groove 4.
As the heat insulating material 3, polystyrene foam, polyurethane foam, polyethylene foam, etc. are used, but polyethylene foamed in a honeycomb shape is preferably used. Blanching pipe 5
Metal tubes such as copper tubes and plastic tubes such as cross-linked polyolefin are used.
Further, the means for attaching the hot water pipe 5 to the groove 4 of the heat insulating material 3 is via gypsum or a bind made of gypsum mixed with metal powder. Furthermore, a heat equalizing plate 6 made of a thin aluminum plate or the like is attached to the upper surface of the hot water pipe 5. A plurality of heat generating panels 2 formed in this manner are arranged between the joists 1.

Further, in FIG. 1, 7 indicates a support member that supports the heat generating panel 2, and this support member 7 includes:
For example, the joist 1 is made of a board stretched between two joists, and the joist 8 is made of a flooring material, such as flooring.

Further, in FIG. 1, reference numeral 9 indicates an elastic material, such as a leaf spring, interposed between the heat generating panel 2 and the support member 7, and this elastic material 9 is interposed in a compressed state,
The heat generating panel 2 is always pressed against the floor material 8. In this case, the entire surface of the heat generating panel 2 is pressed against the floor material 8.

In the above-mentioned embodiment, a plate spring is used as the elastic material 9, but the elastic material 9 is not limited to this and may be any material that has the effect of pressing the heat generating panel 2 against the flooring 8. Any material can be used, and in some cases, rubber, plastic, for example, crosslinked polyolefin foam with a thickness of about 5 mm may be used.

Furthermore, when the above-mentioned hot water type heat generating panel 2 is placed between the joists 1, various forms of arrangement and piping connection may be adopted, but from the viewpoint of workability etc., the following configuration is used. It is desirable to do so.
This will be explained based on FIG. 3 A to E.

The one shown in Fig. 3A uses four hot water pipes buried in parallel in a straight line as the heat generating panel 2, and each of the heat generating panels is arranged so that it is placed over almost the entire area of the room. Arrange three in series between each joist,
These three heat-generating panels are used as a unit block, and the ends of each unit block are arranged in a counter-flow type in which high-temperature hot water on the way out and low-temperature hot water on the way back flow through one heat-generating panel as shown in the diagram. Connection piping 1
0 is connected to improve the heat uniformity effect.

The one shown in FIG. 3B is almost the same as the one shown in FIG.

The one shown in FIG. 3(c) is of a header type in which header pipes 11 are arranged so that three heat generating panels as a unit block constitute a parallel circuit.

The one shown in Figure 3D is a mixture of the loop type shown in Figure B and the header type shown in Figure C. Two sets of three heat generating panels are used as a unit block. Two loop circuits are connected in parallel to the header pipe 11.

The one shown in Figure 3 E is a mixture of the counterflow type shown in Figure A and the header type shown in Figure C, and consists of three sets of three heat generating panels as a unit block. , a circuit is configured in a counter-flow type in which high-temperature hot water going out and low-temperature hot water returning flows in one heat generating panel, and this circuit is connected in parallel to the header pipe 11. Incidentally, the connecting pipes shown in FIGS. 3A to 3E are provided at the corners of the room.

According to the floor heating device of the present invention, an elastic material is interposed between the heat generating panel and its support member so that the heat generating panel is pressed against the floor material. Even if the finishing accuracy is poor or there are foreign objects, the heating panel can be pressed against the flooring without any gaps, and the thermal efficiency can be significantly improved compared to conventional ones. It has the effect of simplifying the construction work because it does not matter if it is worse than the original.
