DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric heating floor for obtaining warmth by electric heating, and more particularly to an electric wiring indispensable for electric heating.

[0002]

2. Description of the Related Art An electric heating floor is constructed by laying a plurality of unit panels on a main body floor. The unit panel has a heat generating sheet inserted between the upper surface plate and the lower surface plate. FIG. 6 shows a unit panel used for a general electric heating floor. The unit panel 1 is composed of three layers, an upper surface plate 2, a heat generation sheet 3 and a lower surface plate. The heat generation sheet 3 is formed by wrapping a heater with an insulating sheet. Supplied.

The lower surface of the upper plate 2 is an electric insulating surface, and the lower plate 4 is an electric insulating surface at the same time as the upper surface. In the electric heating floor, wiring devices such as a lead wire from a heat generation sheet, a power cord, and each outlet plug are indispensable to supply an electric current, and a wiring space for arranging them is required.

Conventionally, to secure this wiring space,
The electric heating floor is raised about 10 cm to 15 cm above the building floor to secure a space, or adjacent unit panels are laid at intervals and a wiring box is provided between them. These floor structures are shown in FIGS. 7 and 8, respectively. FIG.
Is a structure in which a space is secured under the floor. A reinforcing plate 5 is laid below the unit panel 1 and is lifted up by a support column 6 to create a space between the main body floor 7. An outlet 8 is arranged in this space, and a lead wire 9 from the unit panel 1 is connected by a plug 10.

[0005] The structure in which the wiring box is arranged is, for example,
Japanese Patent Application Laid-Open No. Sho 62-217028 proposes a floor heating device shown in FIG. A wiring box 11 is arranged between the unit panels 1, and an outlet 8 is placed in the wiring box 11. The wiring box 11 is provided with a lid 12, which forms a floor together with the upper surface of the unit panel 1. In order to match the level between the upper surface of the unit panel 1 and the upper surface of the wiring box 11, a height is adjusted by applying a spacer 13 under the unit panel.

[0006]

However, since the electric heating floor is laid on the main body floor, its floor surface is higher than the main body floor, and a step is formed between the floor and the main body floor. Especially,
When laying an electric heating floor in a house or the like after construction, if the step is large, danger and inconvenience may occur, and measures such as providing slopes and stairs must be taken to solve this. Further, there has been a problem that it is difficult to take measures such as a lowered ceiling and a reduced space in the room. However, no consideration has been given to the steps in the electric heating floor.

The present invention has been made to solve this problem, and wiring to the unit panel is performed within the height of the unit panel, so that unnecessary space is eliminated and laying work is easy. An object is to provide an electric heating floor with a small step.

[0008]

Means for achieving this object are the following inventions.

A first aspect of the present invention is a heating floor mainly including two types of unit panels, a heating panel and a connection panel. The heating panel has a heating sheet inserted between an upper surface plate and a lower surface plate. In addition, a groove for wiring is provided on the bottom surface of the lower plate, and the connection panel is an electric heating floor having a depression provided on the bottom surface and straddling wiring equipment and wiring.

A heating floor is constructed by combining a heating panel and a connection panel. The heating panel has a heating sheet sandwiched between the upper plate and the lower plate in the same manner as the conventional unit panel, but the bottom panel of the lower plate is provided with wiring grooves on the conventional unit panel. And different. A power cord that connects the lead wire from the heating sheet and the power supply in the room to the wiring device passes through this groove.

The connection panel does not have a heat generating sheet, but has a recess on the lower surface so as to straddle wiring devices such as outlets and plugs and wires such as lead wires and power cords. Although the heating floor is mainly composed of such a heating panel and a connection panel, a non-heating panel having no smaller number of heat generation sheets than the number of heating panels may be combined.

A second aspect of the present invention is the electric heating floor, wherein the connection panels are arranged at intervals of two rows and two columns.

Since the connection panel does not have a heat generation sheet, it is preferable that the connection panel be as small as possible when laying the unit panels in combination. However, as the number of heating panels wired from one connection panel increases, the laying work becomes more complicated. Connection panel with 2 line spacing and 2 lines
When the connection panels are arranged at the row intervals, the laying operation can be easily performed even when the number of connection panels is smaller than the number of heating panels.

[0014]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a heating panel and a connection panel according to the present invention, and the wiring will be described. (A) is a bottom view in which a heating panel 20 is provided with a wiring groove 21 on the bottom surface. Reference numeral 30 denotes a connection panel in which a cavity 31 is provided. Connection panel 3
0 is the outlet 8, the plug 1
0, the lead wire 9 and the power supply cord 19, and they are not pressed.

FIG. 2B is a sectional view taken along line AA of FIG. 2A. The heating panel 20 includes an upper plate 2, a heat generating sheet 3 and a lower plate 4, and a wiring groove 21 is formed in the lower plate 4. Provided,
The lead wire 9 from the heat generation sheet 3 passing therethrough is connected to the outlet 8 with the plug 10 at the tip. The power cord 19 passes under the heating panel 20 by the lead wire 9 and the panel. However, since the wiring devices of the outlet 8 and the plug 10 are gathered under the connection panel 30, the wiring groove 21 may be shallow.

Although the cavity 31 is slightly deeper than the wiring groove 21, the connection panel 30 does not have a heat generation sheet, does not require a special heat insulating layer, and only needs to have sufficient strength. It can be as thick as 20.

Next, an electric heating floor combining a heating panel and a connection panel will be exemplified. FIG. 2 shows an electric heating floor in which only a heating panel and a connection panel are combined. A groove 21 is provided in the center of a heating panel 20 in parallel with a side of the panel. It is connected to the outlet 8 that straddles. In this case, one outlet panel is required for two heating panels.

When laying these panels, outlets 8 connected to a power cord 19 are first arranged in a line, and heating panels 20 are laid on both sides thereof. Next, plugs (not shown) of the lead wires 9 of these heating panels 20
Into the outlet 8, and then lay the connection panel 30. The laying operation is very simple. 29
Is the power supply for the room.

FIG. 3 shows a case where the number of outlet panels for the heating panel is reduced.
Is located in the Keiba Jump. Groove 21 of heating panel 20
Are provided in a cross shape. In this case, wiring is performed from one connection panel to four heating panels. However,
One non-heated panel 25 for four heated panels 20
Is required. Since the non-heated panels 25 are arranged in an intermittent manner, the heating of the room does not cause a bias of the heating source.

The panel is laid in the same manner as in the above example, with the outlet 8 placed first at a predetermined position, the heating panels 20 laid before and after the left and right sides, the lead wire 9 inserted into the outlet 8, and then the connection. The panel 30 is laid. The unheated panel 25 may be laid at any time. The groove 21 of the heating panel 20 is formed in a cross shape because the heating panel 20 can be distinguished vertically and horizontally when there is a pattern on the floor surface. It was made. If there is no such distinction, the groove 21 may be linear as in the case described above.

FIG. 4 shows the connection panels 30 arranged at intervals of two rows and two columns. Eight heating panels 20 are connected to one connection panel 30 around it. In this case, the wiring grooves 21 of the heating panel 20 are provided along the sides of the panel or diagonally. Laying is similar to the previous example and is very simple.

If nine or more heating panels are to be connected to one connection panel, the lead wires of the heating panel not in contact with the connection panel must be passed through the wiring grooves of the other heating panels. Laying work becomes complicated.
Nevertheless, when 24 heating panels are arranged so as to surround one connection panel doubly, first, 18 sheets on the outer circumference are laid at predetermined positions, and wiring for the heating panels on the inner circumference is performed. The lead wire may be laid along the groove in anticipation of the position, and then a heating panel on the inner circumference may be laid. However, when 48 heating panels are arranged so as to surround three layers, the operation becomes very complicated.

[0023]

EXAMPLE An electric heating floor shown in FIG. 2 was laid between eight tatami mats using an outlet having eight outlets on the side. The outlet and plug used for the connection are shown in FIG.
The contact electrode 17 of the plug 10 is flat and has a thickness of 1.2 m.
m, width 8mm, length 1 to ensure sufficient contact area
8 mm. The outlet of the outlet 8 is also a contact electrode 18.
And the overall thickness including the insulating part was 9.2 mm. The total thickness of the plug 10 was 6.2 mm. Although the depth of the depression of the connection panel 30 required 10 mm, the depth of the wiring groove 21 of the heating panel 20 was sufficient if 4 mm.

With the above wiring structure, the thickness of the electric heating floor could be reduced to 20 mm or less. As a result, the height difference from the floor of the main body is significantly reduced, and the feeling that the ceiling is lowered is almost zero, and it is not difficult to use a wheelchair by slightly rounding the corners of the electric heating floor.

[0025]

As described above, according to the present invention,
The unit panel of the electric heating floor is divided into a heating panel with a heating sheet and a connection panel that handles the wiring to the heating panel. The panel is provided with a depression on the lower surface and straddles a wiring device or the like. The wiring groove on the lower surface of the heating panel only needs to pass through the lead wire and the power cord, so it may be shallow, and the depression on the lower surface of the connection panel is slightly deeper. Not required, so both panels have a thickness of 20
mm or less.

Further, by arranging the connection panels at intervals of two rows and two columns in combination with the heating panel, the work of laying the panels is simplified. In this way, the effect of the present invention in which the step with the floor of the main body is reduced and the danger and inconvenience caused by the feeling of pressure and the step of lowering the ceiling are eliminated is great.
