Heating sheet for electric heating mat using covering yarn containing silver coated yarn

The present invention relates to a heating sheet for an electric heating mat that generates heat by receiving a direct current power supply, and more particularly, by configuring a covering yarn containing a silver coated yarn as a +,-electrode part, the structural stability is increased compared to the existing one, and the mat is distorted. Regarding the heating sheet for electric heating mats using a covering yarn containing silver coating yarn, which can be operated without malfunction by keeping the electric connection state without electrical disconnection even by external force such as folding of the mat, etc. will be.

In general,'electric heating mat' is a kind of bedding in which an electric heating wire that generates heat is disposed inside the mat to perform a thermal insulation function by selective power supply by the user. Such an electric heating mat is a mat part. And, it consists of an operation panel connected to the mat portion to control the heating operation of the mat portion.

In order to install the heating wire on the mat, the conventional electric heating mat has a structure in which the heating wire is fixed by sewing it on the mat or bonded using an adhesive or the like.

Therefore, such a conventional electric heating mat takes a lot of work time to attach the heating wire to the mat by sewing, and even if the heating wire is fixed to the mat with an adhesive, it takes a lot of time, and it takes a lot of manufacturing time to increase productivity. Eventually, it had a problem of rising unit prices. In addition, when the heating wire is secured by sewing or fixing with an adhesive, the heating wire is easily separated from the mat, and thus, there is a problem that a breakdown occurs easily.

In addition, the conventional electric heating mat has a disadvantage that it is difficult to fold it during storage because the mat part is not formed thinly but is thick, and it is heavy and difficult to transport.

Accordingly, the present applicant proposed a technology for an electric heating mat that not only can easily and firmly form +,-electrodes, but also can be mechanized and mass-produced in order to solve the conventional problems (Registration Patent No. 10-1639538 )

The electric heating mat of Patent Registration No. 10-1639538 presented to the present applicant includes a mat part heated by receiving a DC power supply, and a base fabric woven with weft and warp, and a base fabric woven together with the base fabric at predetermined intervals in parallel with the base fabric. It is configured to include a plurality of carbon yarns arranged and woven together on the base fabric, each connected to both ends of the plurality of carbon yarns, and comprising a heating sheet composed of a + electrode portion and a-electrode portion made of a verb.

However, the electric heating mat of Patent No. 10-1639538 has a high durability against bending because the company forming the + electrode part and the-electrode part does not have high durability against bending. There was a regret.

Accordingly, the applicant of the present invention in Patent No. 10-1675321, the + electrode part and-electrode part consisting of a covering yarn covered by the company in stretch yarns such as spantens yarn and high elastic urethane yarn to reduce the possibility of breakage or damage due to bending. I made it this way.

However, the company (bare copper wire) is strong in pulling force, but the ductility is not very high, so there is a problem that the electrical connection is cut off due to repeated bending. In other words, in the past, the covering yarn used as an electrode part only covered the company in the new yarn, and when the company is disconnected, there is no configuration as a separate safety measure to maintain the electrical connection without electrical disconnection. There was a problem that electrical disconnection occurred, leading to inability of the mat.

In addition, stretch yarns such as spantense yarn and high elasticity urethane yarn have good ductility, but are weak to heat, so when the heating sheet is manufactured, the stretch yarn melts in the tenta process (ironing process) and the shape of the mat including the heating sheet is changed. As a result of this, the mass production yield was not high and productivity was lowered.

Hereinafter, a heating sheet for an electric heating mat using a covering yarn including a silver coated yarn according to an embodiment of the present invention will be described with reference to the drawings.

The heating sheet 11 is a configuration included in the mat part 10 of the electric heating mat, and is electrically connected to the operation panel 20, and the DC converter 23 is connected to the operation panel 20. As a result, it is configured to generate heat by receiving DC power.

The mat part 10 may be formed in a form in which the insulating coating layers 12 and 13 are formed on the upper and lower surfaces of the heating sheet 11, and the heating sheet 11 and the insulating coating layers 12 and 13 and an outer skin layer covering the outer surface thereof are formed. The mat part 10 may be configured to further include.

The heating sheet 11 includes a base fabric 101 in which a conventional fiber yarn is woven with a weft yarn 103 and a warp 104, and a plurality of carbon yarns 108 formed by being woven together with the base fabric 101 , Weaving together on the base fabric 101 and connected to one end of the plurality of carbon yarns 108 -Electrode 110 and woven together on the base fabric 101 and connected to the other ends of the plurality of It includes a + electrode unit 120.

The base fabric 101 is a fabric obtained by woven general yarns or blended yarns of various materials with the weft yarn 103 and the ramp 104, and when the base fabric 101 is woven, a plurality of carbon yarns 108 and a plurality of strands are formed. A plurality of carbon yarns 108 are formed in parallel with the base fabric 101 at predetermined intervals by weaving them together with a covering yarn, and a plurality of covering yarns are connected to both ends of the plurality of carbon yarns 108 -electrodes The portion 110 and the + electrode portion 120 are formed.

That is, the -electrode part 110 and the +electrode part 120 are made of a covering yarn made of a plurality of strands, and are formed by being woven together on the base fabric 101 so as to be connected to both ends of the plurality of carbon yarns 108. .

In the present invention, compared to the applicant's Patent Registration No. 10-1675321, the covering yarn 130 for forming the -electrode part 110 and the +electrode part 120 is as shown in FIG. 3, aramid yarn 131, silver coating It is characterized by the fact that it is made up of four (132) and nadongseon (133, also referred to as verbs).

Specifically, the covering yarn 130 of the present invention is a member for forming the -electrode part 110 and the +electrode part 120 by being woven together on the base fabric 101, and the aramid yarn 131 and the silver-coated yarn (132) is arranged in parallel to constitute a double core wire, and a bare copper wire 133 is wound and covered by aramid yarn 131 and silver coated yarn 132 arranged in parallel as a double core wire. do.

At this time, the covering yarn 130 is a single type covering yarn that covers the aramid yarn 131 and the silver coated yarn 132 arranged in parallel as shown in Fig. 3 (a) with a single strand of bare copper wire 133 It may be made, or may be made of a double (double) type covering yarn covering the aramid yarn 131 and the silver-coated yarn 132 arranged in parallel as shown in Figure 3 (b) with two strands of bare copper wire 133. In the case of a double-type covering yarn, each of the bare copper wires 133 may be covered in a form in which the aramid yarn 131 and the silver coated yarn 132 disposed in parallel are wound in a spiral shape opposite to each other.

Aramid yarn is a fiber yarn with excellent heat resistance that does not burn or melt in fire, and does not increase even when applied force, and a bare copper wire is a copper yarn with nothing coated on its surface.

In this way, when the covering yarn 130 is used as a member for forming the -electrode part 110 and the +electrode part 120, the heating sheet 11 has structural stability and is electrically disconnected without causing deformation. As it does not occur, the heating mat can be used for a long time without failure.

Specifically, due to the heat generation of the heating sheet 11, even if the silver-coated yarn 132 slightly melts, the aramid yarn 131 is present to withstand heat, so that the covering yarn 130 is structurally deformed. This prevents the -electrode unit 110 and the +electrode unit 120 from being distorted or deformed.

In addition, when viewed from the conductive surface, even if the silver-coated yarn 132 of the covering yarn 130 is melted by heat, the bare copper wire 133 remains, and even if the bare copper wire 133 is physically broken by repeated bending, silver remains. Because of this, the electrical connection can be prevented from being disconnected, and a stable connection of the direct current power source can be maintained.

That is, the low ductility of the bare copper wire 133 is complemented by the high ductility of the nylon yarn 132a of the silver coated yarn 132, so that even if the bare copper wire 133 is physically broken, the silver coated yarn 132 continues the electrical connection. Even if the silver-coated yarn 132 is melted and disconnected due to thermal factors, the bare copper wire 133 maintains the electrical connection, thereby reducing the electrical disconnection phenomenon, thereby realizing a stable operation of the heating mat.
