Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric carpet that can be economically used mainly in combination with a table or an electric kotatsu.

[0002]

2. Description of the Related Art As shown in FIG. 6, a conventional electric carpet generally used for heating a floor is arranged so that a heating area of a heater of a rectangular carpet is divided into two blocks, that is, a left block 11 and a right block 12. The left block 11 and the right block 12 are energized as indicated by the diagonal lines as shown in FIG.
Turn on electricity only to the right block 12 as shown in FIG.
By energizing only one of them, the power consumption is reduced depending on the situation at the time of use and the number of users.

Therefore, as shown in FIG. 9, when a table 13 shown by a broken line is placed in the central portion of this electric carpet and two people are used from two directions, if the left block 11 alone is energized on one side, the heating area becomes insufficient. Therefore, it is necessary to energize the entire surface, and it cannot be economically used by energizing one side. on the other hand,
Even when it is used by one person shown on the left in FIG. 9, when the leg is extended, the leg reaches the right block 12 which is not energized, and the foot is not warm enough. There is.

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. . In addition, as mentioned above, electric carpets are often used in combination with electric kotatsu, which consumes a large amount of power, and other electric heating appliances such as air conditioners and electric stoves. The heating area of the electric carpet is divided and used by appropriately changing it.

Therefore, in order to reduce the power consumption when the electric carpet is used together with other electric appliances, the heating areas of the plurality of heaters are arranged so as to be divided, and the plurality of heaters are energized simultaneously or alternately. Japanese Patent Application Laid-Open No. 62-190
No. 330 is known. In the above-mentioned conventional invention, the heating effect is kept as it is for the purpose of reducing power consumption, but in the present invention, among the heaters arranged in plural for each heating area,
For example, two peripheral 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. Since the heaters are separately provided and the temperatures of the heaters of the two blocks in the peripheral portion and the blocks in the central portion are separately controlled, the control device becomes complicated and the manufacturing cost of the electric carpet increases.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems of the prior art, and it is a table, or a table of an electric carpet used together with an electric kotatsu, or a central portion on which the electric kotatsu is placed. By forming the electric carpet at a temperature higher than that of the surrounding area, it is possible to sufficiently warm the feet without energizing the kotatsu, and to provide an economical electric carpet having a simple structure.

[0007]

In order to achieve the above object, the carpet of the present invention comprises two L-shaped blocks which face each other in a heating area of a heater of a square carpet, and two L-shaped blocks. The rectangular block surrounded by four sides is divided into three parts, and the heater wiring in the rectangular block is arranged more densely than the other blocks, and the heater of the rectangular block is always energized.
Further, one or both of the heaters of the other two L-shaped blocks are energized.

In the above electric carpet, the heater which always energizes the square block at the center where the table or the electric kot is placed is wired more densely than the other parts in the surroundings. Warm and can reduce power consumption. Further, even when the table is placed, the central rectangular block is always energized, so that the feet are warmed. Furthermore, the rectangular block is always energized and either one of the two L-shaped blocks surrounding its four sides or The control device has a simple structure because only the simple control of energizing both is performed.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION An electric carpet according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing a heater 1 of the electric carpet of the embodiment.
This carpet has a square shape, and the heating area of the heater 1 is divided into three, that is, two L-shaped blocks 21 and 22 facing each other and these two L-shaped blocks 21 and 22 are divided into four sides. Enclosed square block 23
It is composed of

Further, the heater 1 of the square block 23
Wiring to another block, namely two L-shaped blocks 2
The heaters 1 and 22 are arranged more densely than the wirings of the heaters 1. For example, in this embodiment, the heater 1 of the L-shaped blocks 21 and 22 has a pitch X of 36 mm, whereas The pitch Y is set to 30 mm, so that the temperature of the rectangular block 23 when the heater 1 is energized is set to be higher than the temperature of the L-shaped blocks 21 and 22 when the heater 1 is energized by, for example, about 5 ° C. in the strong setting.

Next, in FIG. 1, the wiring of the sensor is shown by 3, and the wiring of one sensor 3 and the wiring of the above three heaters 1 are connected to the control device 5, and the heater of the rectangular block 23 is connected. One is always energized, and the other two L
Relatively simple control of energizing either or both of the heaters 1 of the character blocks 21 and 22 is performed.

In the electric carpet having the above structure, as shown in FIG. 2, two L-shaped blocks 21,
22 and the rectangular block 23 in the central portion, the heaters 1 of all the blocks are energized as shown by diagonal lines, and as shown in FIG. 3, the left L-shaped block 21 and the rectangular block 2 are shown.
3 to energize the heater 1, and to energize the L-shaped block 22 and the quadrangle block 23 on the right side as shown in FIG. 4, further, although not shown, energization to all the heaters 1 is stopped. The control to perform is performed by the control device 5.

Therefore, as shown in FIG. 3, when the heaters 1 of the L-shaped block 21 and the rectangular block 23 on the left side are energized, two people place the table in the central portion of the electric carpet as shown in FIG. When 2 is used, each of the two persons with their legs extended at right angles will be satisfied because the legs will be on the heat-generating area even when the one-sided block is energized.

In the heat generating portion of the square block 23 under the foot which is always energized, the wiring of the heater 1 is dense and the temperature is higher than that of the L-shaped block 21, for example, by 5 ° C. in the high setting, so that the foot is warm. This is satisfactory, and it is sufficient to mount the table, but it is not necessary to energize the electric kotatsu even when the electric kotatsu is mounted instead of the table.

[0015]

As described above, according to the electric carpet of the present invention, it is not necessary to energize both the electric carpet and the electric kotatsu even when used together with the electric kotatsu, and in that case, the electric kotatsu There is no need to hang a thick kotatsu futon on the top, so the space can be used much more and cotton dust does not appear in the room.

Also, even if a table is placed in the center of this electric carpet instead of the electric kotatsu, its feet are warmed and a comfortable environment is provided. Further, in the electric carpet of the present invention, the switching of energization for each block, that is, the chamfering of the heating area of the heater on the carpet is simple, the structure of the control device thereof is simple, and the manufacturing cost thereof is also low. . On the other hand, when the electric carpet of the present invention is used together with an electric kotatsu, it is possible to reduce power consumption while maintaining the heating effect as it is.
