DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to 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 applicant's earlier application, Japanese Patent Application No. 8-242855, each panel unit has cutouts at four corners of a square plate-like body, A support leg is provided below and near the notch, and the heat medium circulating pipe is meandered to form one path, and both ends of the heat medium circulating pipe are positioned at one corner notch.

In this configuration, each panel unit includes:
The four heat medium circulation pipes are adjacent to each other as one group so that the respective corners where the both ends of the heat medium circulation pipe are located are opposed to each other, and in the space formed by the cutouts, the ends of the respective heat medium circulation pipes Is connected to the header of the heat medium return pipe and the heat medium return pipe connected to the heat source device, and hot water is circulated and supplied as the heat medium. That is, in this floor heating panel, hot water is circulated and supplied to each panel unit in parallel.

[0004]

As described above, in the conventional floor heating panel in which a plurality of panel units are vertically and horizontally adjacent to each other and have a desired size, the form in which the heat medium is circulated and supplied is limited in parallel. In this configuration, there is no degree of freedom, and in such a configuration, there are many elements for underfloor piping, and the configuration is relatively complicated.

For this reason, connection work is difficult,
There have been problems such as the need to reduce the size of the heating medium supply member such as the header. An object of the present invention is to solve such a problem by configuring the heat medium circulation pipes of a plurality of panel units in a rational configuration as a series path.

[0006]

In order to solve the above-mentioned problems, according to the present invention, first, a notch is provided at each corner of a rectangular plate-like body, and a pipe for circulating a heat medium is provided at each side thereof. Are arranged in four notches so that the ends of the panel units are located in adjacent notches. At least one of the four notches is formed as a straight line. In the constituent floor heating panel,
A plurality of panel units are arranged so that a straight path is on a straight line, and a pipe for heat medium circulation constituting a straight path of a plurality of panel units arranged on a straight line is configured by mounting a series of pipes. In the space formed by the notches facing each other, the other ends of the heat medium circulating pipes of the other predetermined paths are connected to each other by a connecting member, and the ends forming a predetermined pair are connected to the heat source device. We propose a floor heating panel that is connected to a supply member connected to a heat medium return pipe and a heat medium return pipe connected to the floor.

In the present invention, notches are provided at two adjacent corners of a rectangular plate-like body, and two heat medium circulation pipes are provided from one notch to the other notch, and one of the pipes is provided with one notch. A plurality of panel units that are configured as a meandering path and the other path is configured as a linear path are adjacent to each other in the vertical and horizontal directions such that each of the sides provided with the cutouts and the sides not provided with the cutouts is aligned. In a floor heating panel configured to have a desired size, a heating medium circulation pipe that forms a linear path of a plurality of panel units arranged on a line is configured by installing a series of pipes, In any one of the spaces formed by the notches facing each other, a predetermined pair of ends is connected to a supply member connected to a heat medium return pipe connected to the heat source device and a heat medium return pipe,
A floor heating panel is proposed in which the end portions of the heat medium circulation pipes of a predetermined path are connected to each other by a connecting member in another space.

According to the present invention, in the above configuration,
The path of the heat medium circulating pipe may be configured such that the heat medium circulating pipe is mounted and supported in a groove formed on one surface side of the plate-like body.

According to the present invention described above, the heat medium circulating pipes of the plurality of panel units are arranged in series so that the number of heat medium supply members can be reduced. Since the linear path of the panel unit is arranged on a straight line and a series of pipes are attached to the panel unit, a connecting member and a connecting operation of these portions are not required.

In this embodiment, unlike the above-described embodiment, the notches 2 are provided only at two adjacent corners of the plate-like body 1, and one notch 2 a to the other notch 2 b
Is provided in two paths 3s and 3w, one path 3w is configured as a meandering path, and the heat medium circulation pipe 3 is mounted in advance. Also in this embodiment, the heat medium circulating pipe 3 constituting each of the paths 3s, 3w is configured to be mounted and supported in a groove (not shown), similarly to the above-described configuration. The other path 3s is configured as a straight path, and the heat medium circulating pipe 3 is attached to the groove after the plurality of panel units U are adjacent to each other. Other configurations can be appropriately configured similarly to the configuration shown in FIG.

A plurality of the panel units U having the above configuration are
For example, as shown in FIG. 14, the sides 24s provided with the notches 2a and 2b and the side 24w not provided with the notches are arranged adjacent to each other in the vertical and horizontal directions so that they are aligned with each other, and have a desired size. Configure. A series of heat medium circulating pipes 3 are mounted in grooves forming the linear path 3s of the plurality of panel units U arranged on a line, and a space formed by the opposed notches 2 as described above. In the section S, predetermined ends of the heat medium circulating pipes 3 of the respective paths are connected to each other by a connecting member 5, and a predetermined pair of ends is connected to a heat medium supply pipe 6 and a heat medium return pipe connected to the heat source device. By connecting to the supply member 8 connected to 7, the heating medium can be circulated and supplied in series, and a floor heating panel of a desired size can be configured.
