Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to an electric carpet, and more specifically, a pile such as a tufted carpet is knitted on the upper surface of a heater-embedded base material in which an electric heater is incorporated. The present invention relates to an electric carpet that is integrally provided with a carpet body to collect heat.

[Prior Art] Conventionally, in an electric carpet, as shown in FIG. 2, a carpet body 3a in which a pile 2 is knitted on a base cloth 1 formed in a planar shape, and an electric heater 4 are arranged on a holding cloth 5. Heated cloth 6
Heater built-in base material in which two heat insulating base materials 7 and 8 are bonded together
9a and. Latex 10 is interposed between the upper surface of the upper heat insulating substrate 8 and the lower surface of the carpet body 3a. The carpet body 3a and the heater-incorporated base material 9 are integrally fixed by a latex 10.

In addition, a backing 11 is provided on the lower surface of the heat insulating base material 7 at the bottom,
It is fixed by adhesion.

As shown in FIG. 3, the electric carpet configured in this manner is formed in a substantially rectangular shape, and the circular edge portions are joined by sewing with a sewing machine. A connector 12 is provided on one edge of the electric carpet. Both ends of the electric heater 4 are converged inside the connector 12, and both ends of the electric heater 4 are in a one-to-one correspondence with a plurality of pin contacts (not shown) provided inside the connector 12. It is connected to the.

A mating connector 13 having a temperature control function and a power switch is detachably fitted to the connector 12. Actually, a temperature detecting wire such as a sensor wire is arranged inside the heater built-in base material 9 on the carpet and is connected to the pin contact inside the connector 12, so that the mating connector 13 The temperature is controlled by the internal temperature control function (temperature controller).

Such temperature control is well known as temperature control for electric carpets, and a description thereof will be omitted.

A power cord 14 is connected to the mating connector 13 for controlling the temperature and supplying electricity to the electric heater 4 and the like.

The heat insulating base materials 7 and 8 of the heater built-in base material 9a have a cushioning property, for example, urethane foam is used, and the heat insulating base material 7 at the lower portion is made thick to prevent heat from radiating. The upper heat insulating substrate 8 is formed thin.

On the other hand, the latex 10 is applied to the back surface of the carpet body 3, and by applying the latex 10 to a thick wall, the latex 10 is firmly adhered to the base cloth 1 and the pile 2. Further, since this latex 10 is applied thickly, a large uneven surface is formed on the surface opposite to the base cloth 1, that is, the surface of the latex 10 adhered to the upper surface of the upper heat insulating substrate 8. Since the uneven surface of the latex 10 is absorbed by the elasticity of the upper heat insulating substrate 8 and the latex 10 is adhered to this heat insulating substrate 8, the surface of the carpet body 3a becomes substantially flat as a whole.

In such an electric carpet, heat is transferred to the holding cloth 5, the upper heat insulating base material 8, the latex 10 and the base cloth 1 by the heat generated by the electric heater 4 to collect heat.

[Problems to be Solved by the Invention] However, since the upper heat insulating substrate 8 and the latex 10 are provided between the electric heater 4 and the base cloth 1, the thermal conductivity is poor.

Further, when the over carpet 15 as shown in FIG. 3 is laid and used on the upper surface of the carpet body 3a, the heating effect is further deteriorated.

Therefore, the electric heater 4 consumes a large amount of electric power and becomes an uneconomical electric carpet.

Furthermore, since the base cloth 1 is formed in a net-like shape using thick and hard threads such as burlap cloth, the latex 10 must be applied thickly and adhered.

For this reason, the uneven surface of the latex 10 becomes large, and it is required that the latex 10 be substantially thick and adhere to the heat insulating base material 8 on the upper side, which is against the thermal conductivity.

Originally, it is better to directly bond the latex 10 to the upper surface of the heating cloth 5, but the thermal conductivity is better. However, when the base cloth 1 and the latex 10 are bonded, since the latex 10 is thick, Since there is a large uneven surface, base cloth 1
Even if the latex 10 is adhered to the upper surface of the above, the adhesion area is small and it easily peels.

Therefore, an object of the present invention is to provide a thin electric carpet which has good heat conduction and requires a small amount of heat insulating substrate and latex.

[Means for Solving the Problem] The electric carpet of the present invention is an electric carpet having a planar heater-incorporating base material and a carpet body integrally fixed to the upper surface of the heater-incorporating base material by adhesion. In the above, the heater built-in base material is a heat insulating base material formed in a planar shape,
An electric heater is provided on one side of a holding cloth, and the carpet body has a base cloth in which piles are knitted and a cotton-like material polymerized on the back side of the base cloth. On one side of the substrate, the electric heater of the heating cloth is provided so as to face the electric heater, and the heating cloth is integrally provided by adhesion, and a latex is provided on the cotton-like body on the back surface side of the carpet body, and the latex is used to The heater built-in base material and the carpet body are integrally bonded and fixed.

In addition, the adhesion between the heater built-in base material and the carpet body by latex is performed in the pile portion, and the cotton-like body portion other than the pile is solidified by the latex in the cotton-like body and the air layer is formed between the heating element and the base cloth. A plurality of air layers are formed in the cotton body.

[Operation] According to this electric carpet, the latex is impregnated into the cotton-like material, and the latex permeated and absorbed by the cotton-like material fixes the base cloth and the pile, so that the latex is substantially formed into a thin wall, and Since the latex surface formed on the back surface becomes almost flat and can be adhered to the heating cloth surface, and an air layer is also formed on the cotton-like body, heat conduction from the heating cloth to the surface of the base cloth is promptly performed.

Further, since the heating cloth and the latex are integrally bonded, a thin electric carpet is obtained, and the bending rate is improved.

[Embodiment] FIG. 1 shows an embodiment of a part of the electric carpet of the present invention. In this embodiment, the same parts as those in FIG.

Incidentally, the electric carpet shown in FIG.
Since it has the same appearance as the electric carpet shown in the figure,
The description will be made with reference to the drawings.

The heater-embedded base material 9b has a heat insulating base material 7 and a heating cloth 6 bonded to the upper surface of the heat insulating base material 7. The electric heater 4 disposed on the heat generating cloth 6 digs into the heat insulating base material 7 made of soft urethane foam, and is firmly fixed to each other on both sides of the heat generating cloth 6 and the heat insulating base material 7.

On the other hand, the carpet body 3b is a base cloth 1 in which piles 2 are knitted.
And a polymerized cotton-like body 16 on the back surface of the base cloth 1.
Latex 10 is provided on the back surface of the carpet body 3b. The carpet body 3b and the heater-embedded base material 9b are adhered and fixed integrally by the latex 10.

The cotton-like body 16 is made of polyester, polypropylene, cotton, or the like, and if it is rectangular like the electric carpet shown in FIG. 3, it is formed according to the predetermined dimensions of the electric carpet. , The yarn that is inserted and knitted to form the pile 2 is attached to the back surface side of the base fabric 3. When the pile 2 is knitted on the base cloth 1, a gap is created in the base cloth 1.

The latex 10 prevents the cotton-like material 16 and the pile 2 from separating from the base cloth 1.

The latex 10 is applied from the back surface side of the carpet body 3b by a spray gun or a coating jig such as a coating roll.

The holding cloth 5 uses spunbond, and the electric heater 4 is used.
The electric heater 4 is fixed to the holding cloth 5 by applying a heat press after the wiring cloth is arranged on one surface of the holding cloth 5. Further, the holding cloth 5 has a heater-embedded base material 9b made by adhering and fixing the surface of the heat insulating base material 7 to the upper surface melted by heat.

Since the carpet body 3b has a configuration in which the latex 10 is applied to the back side via the cotton-like body 16, the latex 10
The pile 2 is adhered to the base cloth 1 via the cotton-like body 16 by the above, and the latex 10 is permeated and absorbed by the cotton-like body 2 without forming a layer of the latex 10 over the entire back surface side of the base cloth 1. , The latex 10 will solidify.

At this time, due to the permeation and absorption of latex 10, a plurality of small holes 17
Is formed.

The cotton-like material 16 causes the latex 10 in the gap formed in the base cloth 1.
Can be prevented as much as possible to maintain the gap, and as a result, the air permeability of the carpet body 3b can be sufficiently ensured.

Therefore, the heat radiated from the electric heater 4 passes through the small holes 17 of the latex 10 and is efficiently conducted from the gap of the base cloth 1 to the surface side of the carpet body 3b as a hot air-strengthened flow.

[Effects of the Invention] As described in the above embodiments, the carpet body is provided with latex on the back surface side of the carpet body via the pile knitted base cloth and the polymerized cotton-like material on the back surface side of the base cloth. The latex firmly adheres and fixes the heater-embedded base material and the carpet body to each other, whereby the pile firmly adheres the carpet body and the heater-embedded base material, and the pile is attached to the base fabric through the cotton-like material. The latex is firmly adhered to prevent its separation, and the latex is permeated and absorbed in the cotton-like material, and the latex is adhered and fixed integrally to the heater-embedded base material and the carpet body to thereby effect the carpet. Since the latex applied to the back surface of the main body directly adheres the heating cloth, the heat radiated from the electric heater is well transferred to the main body of the carpet.

Therefore, it is possible to prevent the latex from entering the gaps generated in the base cloth as much as possible, and the gaps are retained, whereby the air permeability of the carpet body is sufficiently ensured.

Further, when latex penetrates into the cotton-like material, small holes are formed in the latex surface formed on the back side of the carpet body, so the heat radiated from the electric heater directly flows from the heating cloth to the gap between the base cloth, It passes through and becomes a heat flow, which conducts to the surface side of the carpet body extremely efficiently.

In the electric carpet having such a configuration, since the heater-embedded base material and the carpet body can be integrally fixed by the thin latex, the entire thickness becomes thin, and the flexibility is improved as compared with the conventional thick electric carpet. At the same time, the power consumption of the electric heater and the heat insulating base material can be saved.
