2. Description of the Related Art Conventionally, an electric carpet generally used for floor heating is arranged such that a heating area of a heater of a rectangular carpet is divided into a left block 11 and a right block 12 as shown in FIG. As shown in the figure, both the left block 11 and the right block 12 are energized as shown by oblique lines, only the left block 11 is energized as shown in FIG. 11, or only the right block 12 is energized as shown in FIG. By doing so, the power consumption can be reduced depending on the situation at the time of use and the number of users.

Therefore, as shown in FIG. 13, a table 13 indicated by a broken line is placed at the center of the electric carpet, and when two persons are used from two directions, if only the left block 11 is energized on one side, the heat generation area becomes insufficient. Therefore, the entire surface must be energized, and economical use by one-sided energization cannot be achieved.

On the other hand, even when one person is used by one person as shown on the left in FIG.
, The feet reach, the warmth of the feet is insufficient, and there is a drawback that the feet do not warm unless the entire surface is energized.

That is, the left block 1 of the electric carpet
If only 1 is energized, the warmth of the feet will be insufficient, and if an electric kot is placed in place of the table 13 on the electric carpet and both the electric carpet and the electric kot are energized, the electric bill will be bulky and not economical. .

As described above, electric carpets are often used in combination with electric kotatsu and other electric heating appliances such as air conditioners and electric stoves, which consume large amounts of power. From the viewpoint of the capacity, the heating area of the electric carpet is divided and used appropriately.

Therefore, in order to reduce power consumption when another electric appliance is used in combination with the electric carpet, a plurality of heaters are arranged so as to divide the heating area, and the plurality of heaters are energized simultaneously or alternately. Japanese Patent Application Laid-Open No. 62-190 relating to a floor heating device characterized by comprising
No. 330 is known.

In the above-mentioned conventional invention, the purpose is to reduce the power consumption while keeping the heating effect. In the present invention, however, of the heaters provided for each heating area, a plurality of heaters are provided. , For example, 2
The two blocks are energized simultaneously or alternately, and a thermistor that detects the temperature of two heaters that are energized alternately and a thermistor that detects the temperature of the heater of the central block are separately provided. In addition, since the temperatures of the heaters of the two blocks in the peripheral portion and the block in the central portion are separately controlled, there is a problem that the control device becomes complicated and the manufacturing cost of the electric carpet increases.

[0009] In recent years, in order to enjoy the harmony of family and friends, there is a tendency to place a round table on the electric carpet without discrimination at a sitting position, and the demand for round kotatsu is also increasing. There is a tendency.

Further, when the electric carpet is laid on the floor, power is supplied to a heater provided in the electric carpet, and the position of the control device for switching the heating area and adjusting the temperature is determined by the position of the electric carpet. Is preferably as close as possible to the power outlet in the room where the electric carpet is laid, in terms of safety and appearance when using the electric carpet.

On the other hand, although the electric carpet shown in FIGS. 10 to 13 has a square shape, if the room in which the carpet is laid is narrow and there is furniture or the like in the corner of the room, the square carpet may be used. The corners of the main body interfere with the furniture and the like, and the furniture and the like are placed on the corners, causing troubles such as causing a failure.

[0012]

SUMMARY OF THE INVENTION The present invention can be laid without interference with furniture and the like even in a small room where furniture and the like are placed at the corners. In addition, a cord from a control device for an electric carpet can be connected to a power outlet provided in a room in the shortest distance, thereby providing an economical electric carpet.

[0013]

SUMMARY OF THE INVENTION The present invention provides a carpet body having a round or polygonal, preferably pentagonal or higher, heating surface of a heater with two or more fan-shaped peripheral blocks opposed to each other. An electric carpet divided into at least three parts: a central block having an outer periphery surrounded by these two or more outer peripheral blocks, and wiring of heaters in the central block is arranged more densely than each outer peripheral block. An electric carpet is provided which is provided with a control device that constantly supplies electricity to the heaters in the central block and supplies electricity to all or some of the heaters in the outer peripheral block.
