Abstract

PROBLEM TO BE SOLVED: To dissolve a problem that a complicated site work, such as a previous groove processing in plywood for structure, a work to bury piping and a wiring for heating in the groove during execution of a work, groove positioning, etc., is needed, and professional craftsmen and quantities of work amounts are needed. SOLUTION: A spacer is situated at a peripheral part between a surface plate member and a back plate member to form a space. Heat insulation sheets are laid under the space, planar heating substances 5 are placed thereon, and a warp is prevented from occurring for a long period by keeping a balance between temperature generated by heat working in the back plate member and the temperature of the surface plate member. The positions of a jack and a plug are disposed in a side position near and corresponding to either end part. By combining floor-heating units, having an axially symmetrical structure with respect to the end part, with each other, an electric connection part is unified. The adjacent units are electrically interconnected through the plug and the jack and the whole surface or a part of the surface of a room floor forms a floor-heating device.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a unit-type floor heating device.

[0002]

2. Description of the Related Art Floor heating is an ideal heating method for head and foot heat. At present, there are an electric heating method and a hot water heating method.
The electric type uses a panel on which a cord heater is wired as a floor material. In the hot water system, hot water drawn from a boiler such as gas or petroleum is circulated through a synthetic resin tube provided on a flooring. Conventionally, when constructing a house, structural plywood (equivalent to a thickness of 12 mm) having a groove for piping or wiring provided below the wooden floor surface material is spread over the entire room, and the plywood and the like are used for hot water heating. After embedding resin piping or heating wiring for electric heating, a wooden floor surface material (8 to 12
mm thickness).

[0003]

In these systems, complicated on-site work such as pre-groove processing of a structural plywood and embedding work in a heating pipe or wiring groove at the time of construction and alignment of the groove are required. Requires a lot of work with craftsmen. In addition, since the heating element is buried in the underlying structural plywood, the heat conduction efficiency to the floor surface is deteriorated and the energy use efficiency is reduced.
Warpage occurs in the floor surface material within 3 years, and in some cases, rebuilding is required.

[0004]

A first means for solving the problems of the present invention is to form a space by installing a spacer in a peripheral portion between a front plate member and a back plate member, and forming a space in the space portion. Is a floor heating unit in which a sheet heating element is provided on the upper side of the sheet and a heat insulating sheet (mat) is provided on the lower side. A second means for solving the problem of the present invention is the floor heating unit described above, which is a plywood in which a front plate and a back plate are laminated with a veneer on the front and back surfaces. Third aspect for solving the problem of the present invention
Means is to form a processed portion with the front and back plate members and the spacers sandwiched therebetween to form a joint between the units, and to attach a three-pole plug to one of the end portions on one side. And a three-pole jack is provided on the other side of the same one end part. A fourth means for solving the problem of the present invention is to provide a buffer member at a junction between the unit and the three-pole plug and / or three-pole jack,
The underfloor heating unit according to the above, wherein the positional accuracy for inserting and connecting the three-pole plug and the three-pole jack is reduced.
