[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a floor heating panel unit processing method and a floor heating panel.

[0002]

2. Description of the Related Art In recent years, it has been proposed that a plurality of panel units provided with a pipe for circulating a heat medium are arranged vertically and horizontally to form a floor heating panel of a desired size. For example, in the specification and drawings attached to the application of the applicant of the present invention, Japanese Patent Application No. Hei 8-242855, each panel unit has a square plate-like shape as shown in FIGS. a

Connection members. This groove is formed by processing the upper surface of the plate-like body a using a router.

[0005]

Conventionally, the grooves formed on the upper surface of the plate are formed by processing with a router, which is troublesome. On the other hand, since the aluminum sheet for soaking is in contact with only the upper surface of the heat medium circulating pipe, the efficiency of heat transfer from the heat medium circulating pipe to the aluminum sheet is relatively poor. Required, which is disadvantageous in terms of cost. Therefore, improvement of such points is desired. An object of the present invention is to solve such a problem.

Next, an embodiment of the present invention will be described with reference to the drawings. First, FIG. 1 is a plan view showing a first embodiment of a panel unit U to which the present invention is applied, and FIG. 2 is a sectional view taken along line AA of FIG. Reference numeral 1 denotes a plate-like body, and the plate-like body 1 is a square, and each corner has a notch 2 (2a, 2) in the shape of a right-angled isosceles triangle cut diagonally.
b, 2c, 2d). On the upper surface of the plate-like body 1,
The four paths 3a, 3b, 3c, 3d of the heat medium circulating pipe 3 are configured such that the respective ends are located in the adjacent notches 2, and among the four paths of the heat medium circulating pipe 3, ,
The route 3d has a meandering configuration and the other routes 3d.
a, 3b and 3c are configured as linear paths. However, the number and shape of the paths of the heat medium circulation pipe 3 are appropriate. These paths are formed by mounting a heat medium circulation pipe 3 in a groove 4 formed on the upper surface of the plate-like body 1 as shown in FIG. Further, on the upper surface of the plate-like body 1, including the inside of the groove 4, a heat equalizing layer 5 of a material having high thermal conductivity, for example, aluminum or copper is formed.

FIGS. 3 and 4 are schematic views for explaining a method of processing the groove 4 according to the present invention. First, as shown in FIG. 3, the plate-like body 1 before processing is flat, and a material 6 having high thermal conductivity, for example, a heat equalizing sheet 6 such as aluminum or copper is placed on the upper surface thereof. For example, in the case of aluminum, the heat equalizing sheet 6 has a thickness of about 50 μm, and is placed on the upper surface of the plate-like body 1 by simply placing it or bonding it with an adhesive. . Reference numeral 7 denotes a male die for press working, and the male die is formed with a ridge 8 corresponding to the groove 4 constituting the above-described path. Then, the upper surface of the plate-like body 1 on which the heat equalizing sheet 6 is stacked is press-formed by the male mold 7 to form the above-described path on the upper surface of the plate-like body 1 as shown in FIG. The groove 4 is easily formed, and at the same time, a heat equalizing layer 5 including the inside of the groove 4 is formed on the upper surface of the plate-like body 1 by the heat equalizing sheet 6 stacked in advance.

By mounting the heat medium circulating pipe 3 in the groove 4 formed on the upper surface of the plate-like body 1 as described above, the above path can be formed. At this time, if the heat medium circulating pipe 3 to be mounted at a predetermined position of the groove 4 is plastically deformed in advance into the shape of the path formed by the groove 4 or a shape close thereto, the mounting can be easily and reliably performed. When the heat medium circulating pipe 3 is thus mounted in the groove 4, at least the lower half of the outer periphery of the heat medium circulating pipe 3 abuts on the heat equalizing layer 5. 5 has good heat transfer efficiency. Accordingly, after a plurality of panel units U are vertically and horizontally adjacent to each other to form a floor heating panel of a desired size,
When the laminating plate 9 and the finishing floor plate are combined with each other on the upper side of the panel unit U and used as a floor, it is possible to improve the uniformity of heat in the width direction of the floor heating panel.

When the laminating plate 9 and the finishing floor plate are placed on the upper side of the plate-like body 1 on which the heat medium circulation pipe 3 is mounted and joined together, FIG.

In the above embodiment, the heat equalizing layer 5 including the inside of the groove 4 is formed on the upper surface of the plate-like body 1 by the heat equalizing sheet 6 stacked in advance. After forming the heat medium circulating pipe 3 in the groove 4 without forming the heat equalizing layer 5 inside the heat equalizing layer 5, the heat equalizing layer 5 ′ may be formed by covering the upper side with the heat equalizing sheet 6 ′. Also in this case, there is an advantage that the groove 4 constituting the path of the heat medium circulation pipe 3 can be formed with a small amount of labor.

As described above, the grooves 4 are formed by pressing.
At the same time, other elements of the plate-like body 1, for example, the notch 2 and a low step portion described later can be processed at the same time.

Here, if the plate-like body 1 is made of a material that can be processed by pressing and can support the load on the floor,
A suitable material such as a wood plywood, a particle board, a foamed plastics board, or a composite thereof can be used. When the plate 1 is made of plastic, a method of forming a groove with a mold at the time of forming the plate can be applied instead of the press working.
In order to provide the heat equalizing layer in this method, a heat equalizing sheet made of a material having a high thermal conductivity may be arranged on the groove forming die side when the plate-like body is formed.

The heating medium used for the floor heating panel according to the present invention is, for example, hot water. In this case, the heating medium circulating pipe 3 is made of a material having excellent pressure resistance, heat resistance and durability, such as crosslinked polyethylene. Pipes can be used. The notch 2 of the plate-like body 1 is formed into a right-angled isosceles triangle in which a corner of the plate-like body 1 is notched as described above.
The plate-like body 1 may be formed in a shape similar to that of the related art, that is, a square shape in which corners of the plate-like body 1 are cut out at right angles.

In addition, the positions where the support legs 10 are arranged are notches 2 (2a, 2) of at least four corners.
Other than being provided in the vicinity of (b, 2c, 2d), it can be set at an appropriate position other than the above-mentioned position, and in some cases, it can be a floor heating panel unit having no support legs.

In the above configuration, when a plurality of panel units U are arranged vertically and horizontally adjacent to each other, as shown in FIG.
Is formed in a square space S having a shape rotated by 45 ° with respect to the shape shown in FIG. Therefore, in this space S, predetermined ends of the heat medium circulating pipes 3 of the respective paths 3a, 3b, 3c, 3d are connected to each other by the connecting member 11, and the respective paths are communicated. Heat medium circulation pipe 3 for each path to be formed
