Abstract

PROBLEM TO BE SOLVED: To permit floor heating, excellent in thermal efficiency and reduced in the temperature fluctuation of a floor panel, by a method wherein a heat radiation panel, provided with an electric heating wire, passed through a tubular body formed integrally on the lower surface of the heat radiating panel, and heat storage body, filled so as to surround the electric heating wire, is pushed against the lower surface of the floor panel employing a spring. SOLUTION: Tubular bodies 13 are formed integrally with one side of a heat radiating panel 10 with a shape projected downward. A covered electric heating wire 15 is passed through the tubular bodies 13 and heat storage body 16 is filled into the circumferential space of the electric wire. The heat radiating panel 10 is preferably made of a metal in order to reduce heat resistance. Supporting fittings 19 are attached to a joist 12 while the heat radiating panel 10 is placed on the springs 23 of respective supporting fittings 19. Then, a floor panel 11 is abutted against the joists and is fixed to the joists 12 so as to compress the springs 23. Then, the electric heating wire is excited whereby the heat storage body 16 is heated by joule heat and, further, the tubular bodies 13 and the heat radiating panel 10 are heated. The heat radiating panel 10 is contacted with the floor panel 11 closely whereby heat is transferred to the floor panel 11 efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric heater used for floor heating of houses and the like.

[0002]

2. Description of the Related Art A conventional electric heater for floor heating is merely a striated body and is installed so as to be routed on a heat insulating material laid under a floor plate. Originally, in such an electric heater, the adhesion between the electric heater and the floor plate was insufficient, and the bulk of the heat insulating material decreased over time, and the gap between the heater and the floor plate tended to increase over time. For this reason, there is a problem that the efficiency of heat transfer from the heater to the floor plate is poor, and the running cost is high.

An electric heater is a mere electric wire and has a small heat capacity. If such an electric heater is turned on and off, the temperature of the floor plate drops sharply when power is turned off, and comfortable heating is achieved. Hateful.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide an electric heater for floor heating which has good thermal efficiency and little temperature fluctuation of a floor panel.

[0005]

According to the panel heater of the present invention, a tube is integrally formed on the lower surface of the heat radiating panel. A heating wire is passed through the tube, and a heat storage body is filled in the tube so as to surround the heating wire. The heat radiating panel is pressed against the lower surface of the floorboard using a spring. The spring may be fixed to the heat dissipating panel in advance, or may be supported by an L-shaped support fitting attached to the joist.

[0006]

[Function] A spring pushes a heat radiating panel upward from the bottom to make it closely adhere to a floor plate. Therefore, heat is efficiently transmitted from the heat radiating panel to the floor panel. Moreover, since the heat storage body surrounding the heating wire stores heat, even if the power of the heating wire is repeatedly turned on and off, the temperature fluctuation of the floorboard is small, and comfortable heating can be performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the panel heater is housed in a heat radiating panel 10. FIG. The radiating panel is the floor panel 1
It has an elongated shape that fits between the joists 12 supporting the 1 and is formed to have a width of 22 cm and a length of 1 m (or 2 m) in this embodiment. The heat radiation panel 10
It is preferably made of metal to reduce the thermal resistance, and in this embodiment is made of aluminum.

On both sides of the heat radiating panel 10, a tubular body 13 is integrally formed with a shape protruding downward. The outer diameter of the tube 13 is 30 mm in the embodiment. The tube 13 is filled with a heat storage material (for example, granular ceramic) so as to pass the coated heating wire 15 and fill the surrounding area. The power of one panel is 75 watts with a length of 1 m and 6
Use 6 to 10 of these panels between tatami mats. Reference numeral 17 in FIG.
Denotes a rubber cap, and reference numeral 15a denotes a lead wire of a heating wire.

A support fitting 19 is used to press the heat radiating panel 10 against the lower surface of the floor plate 11. As shown in FIG. 3, the metal fitting 19 is a metal band 20 whose main body is bent in an L-shape, and a nail 21 bent in an L-shape is extended from the metal band. A cylindrical receiver 22 is formed near the end of the band 20, and a coil spring 23 is fitted into the cylindrical receiver. As shown in FIG. 1, the support fitting 19 can be easily attached by hitting the claw 21 on the upper surface of the joist 12 with a hammer.

In this manner, the support fittings 19 are attached to the joists (the number is 4 to 6 per one heat dissipation panel), the heat dissipation panel 1 is placed on the spring 21 of each support fitting, and the floor plate 11 is pressed from above. The floor plate is fixed to the joist 12 by compressing the spring. This causes the compressed spring 23 to expand and press the heat radiating panel 10 against the lower surface of the floor plate 11.

[0011] The Joule heat generated when the heating wire is energized first heats the ceramic which is the heat storage body 16,
Further, the tube 13 and the heat dissipation panel 10 are heated.
Since the heat radiating panel and the floor panel are in close contact with each other, heat is efficiently transmitted from the heat radiating panel to the floor panel 11.

When the temperature of the heat radiating panel 10 becomes higher than a certain value, the heat radiating panel 10 is actuated by a controller (not shown).
Power supply to is stopped. In this case, the heat stored in the heat storage body 16 flows to the floor plate 11.

In the drawings, reference numeral 25 denotes an underfloor panel, and reference numeral 26 denotes a heat insulating plate made of polyurethane or the like.

[0014]

As described above, according to the present invention, the heat radiating panel is pushed up from below by a spring and is brought into close contact with the floor plate, so that heat is efficiently transmitted from the heat radiating panel to the floor plate, and the electricity bill is reduced. Can be saved. In addition, a heating wire is passed through a tube integrally formed on the lower surface of the heat dissipation panel,
Since the heat storage body is packed in the tube so as to surround the heating wire, even when the power of the heater is turned on or off, the temperature fluctuation of the floor plate is small and comfortable heating can be performed.

If an L-shaped support is attached to the joist and the spring is supported on the support, the spring can be firmly held and the construction is easy.
