[Structure] In a connecting portion 3 for detachably connecting the heating and controlling controller portion 2 of the heat generating portion 1 to the heat generating portion 1, corresponding connecting pins 4A, 4B to 4F, 4G and respective receiving gold 5A, 5B. 5F and 5G are electrically symmetrically arranged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 With the present invention, whether the front side of the heat generating part is used for the front side or the back side of the heat generating part is used for the front side, simply replace the controller part with the surface side to be used and replace it with the heat generating part. The present invention relates to an electric carpet that can be used on both front and back sides.

[0002]

[Prior Art]

 The material and thickness of the front and back fabrics of conventional electric carpets are different, and in general, only the front fabric is used with the top face at all times, so the front fabric surface is heavily soiled. In that case, there was a strong demand to turn the electric carpet over and use it.

In addition, the position of a power outlet in a room where an electric carpet is laid is often restricted, and most of them use an extension cord or the like. However, since the arrangement of the connection pins and the receiving pins in the connection part that connects the heat generating part of the conventional electric carpet and the controller part for heating and controlling the heat generating part is not symmetrical, the backing material of the heat generating part is not symmetrical. Even if you try to connect the controller side to this side with the side facing up, there was a problem that it could not be connected because of the asymmetrical arrangement of connection pins, or it was electrically misconnected.

Therefore, although a projection for preventing reverse connection may be provided on the case portion of the connection portion, the idea that a user uses the heat generating portion and the controller portion by reversely connecting them has not been heretofore known.

[0005]

[Problems to be solved by the device]

 The present invention has been made in order to solve the above-mentioned conventional problems, in which the controller portion connected to the heat generating portion of the electric carpet that enables use of both the front and back cloth is a front cloth or a back cloth. The problem to be solved is to provide an electric carpet that can be smoothly connected and operated in the same manner regardless of which side of the lining material is used as the front side.

[0006]

[Means for Solving the Problems]

 As a means for solving the above-mentioned problems, the electric carpet of the present invention is configured such that the controller portion for heating and controlling the heat generating portion is detachably connected to the heat generating portion, each corresponding connecting pin and each receiving pin. And are electrically symmetrically arranged.

In this case, it is desirable that the heat generating area of the heat generating portion is divided into a plurality of parallel zones, and that each connecting pin and each receiving metal are provided in the divided parallel directions.

[0008]

[Work]

 With the above configuration, even if either the front fabric side or the back fabric side of the heat generating part is used as the front side, by simply replacing the controller part, heating and control of the heat generating part will be normal. Done.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a case where a controller unit 2 is to be connected with the surface material 1A of the heat generating unit 1 as a table. The respective connection pins of the connection part 3 for detachably connecting the controller part 2 are indicated by 4A, 4B to 4F, 4G, and the respective receiving moneys corresponding to these are indicated by 5A, 5B to 5F to 5G. The respective connection pins 4A to 4G and the respective backings 5A to 5G are electrically symmetrically arranged.

Further, FIG. 2 shows a state in which the heat generating portion 1 and the controller portion 2 in FIG. 1 are connected, and FIG. 3 shows a state in which the electric carpet of FIG. 2 is laid in the room 6. The controller section 2 is brought near the position of the outlet 7 and the power cord 8 is connected to the receptacle 7. Next, FIG. 4 shows a case where the backing material 1B of the heat generating portion 1 is turned upside down and the controller portion 2 is to be connected thereto. With respect to the heat generating portion 1, each connecting pin of the connecting portion 3 is opposite to that in FIG. 4G, 4F to 4B and 4A, and the respective receipts corresponding to these are shown as 5A, 5B to 5F and 5G.

Further, FIG. 5 shows a state in which the heat generating portion 1 and the controller portion 2 in FIG. 4 are connected, and FIG. 6 shows a state in which the electric carpet in such a state is laid in the room 6. Next, FIG. 7 shows an overall circuit diagram of the electric carpet, in which the heat generating part 1 and the controller part 2 are connected by a connecting part indicated by an alternate long and short dash line indicated by an arrow 3, and the controller part 2 is connected. in this state, even if Re table cloth 1A or back fabric 1B noise of the heat generating portion 1 are connected at the connection portion 3 by using in the table, on-off switch SW ₂ to the heating unit 1, the SW ₃ It can be seen that the side, the heat generating portion 1, and the heat generating area do not change.

The heating area of the heat generating portion 1 is divided into a plurality of parallel zones, and the connecting pins 4A to 4G and the receiving moneys 5A to 5G are provided in the divided parallel directions. Because there is. In this case, in particular, the switching display of the heat generation area of the controller unit 2 only shows the form of the heat generation unit 1, and since the heat generation unit 1 is not labeled as A surface, B surface, etc. It can be applied to this embodiment.

Next, in FIGS. 8 and 9, the heat generation area of the heat generating portion 1 is divided into a plurality of zones parallel to each other by the alternate long and short dash line Y, and the connecting pins 4A, 4B, 4C are arranged in the divided parallel directions. FIG. 8 shows another embodiment in which each of the receivables 5A, 5B, and 5C is provided. FIG. 8 shows a case where the table cloth 1A of the heat generating part 1 is used as a table, and FIG. 9 shows a back cloth 1B. When using as a table.

That is, if the controller part 2 is connected to the connection part 3 of the heat generating part 1 with its front surface facing upward as shown in FIGS. 8 and 9, the surface of the heat generating part 1 is cut regardless of the front and back of the electric carpet body. The operation portion of the controller portion 2 of the portion coincides only with the zone on the left side indicated by the hatched line X in FIGS. Therefore, it is not necessary to make the operation unit of the controller unit 2 have a complicated structure such as being provided on both front and back surfaces.

[0015]

[Effect of the device]

 According to the electric carpet of the present invention described above, the controller section having the operation section on one side can be applied to an electric carpet in which either the front cloth or the back cloth of the heat generating section can be used as the front side. Depending on the atmosphere of the room in which it is laid, the front or back fabric can be used for the front and back, and the range of use of the electric carpet can be expanded.

Further, since the connection part of the controller part is usually provided on one end side of the heat generating part, the position of the controller part changes depending on whether the heat generating part is on the front side or the back side. For example, when a cover is used together with an electric carpet, the heat generating part cannot be seen by the cover, so by selecting either the front or back side of the heat generating part so that the controller part comes close to the outlet, You can bring the power cord of the controller near you.

As a result, there is no need to connect an extension cord to a power cord from an outlet, the appearance is improved with the shortest wiring, and there is an effect that electrical loss due to the extension cord is eliminated.
