Abstract

The present invention relates to the heating wire structure shape of the woven heating element (Utility Model Registration No. 110067).

According to this bill,

It is intended to further increase the durability of the heating wire by thinning and double-wiring the heating element of the conventional woven heating element (Utility Model Registration No. 10067, the applicant is the applicant).

Description

Woven heating element in which the heating wire of the metal thin wire constituting the woven heating element (Utility Model Registration No. 10067) has a double wire structure. {CLOTH SHAPE WOVEN HEATER CONSISTS OF THIN MATAL WIRES ARE DOUBLE STRINGS.}

The present invention relates to a heating wire structure shape of the woven heating element (1).

Conventionally known and used woven heating element (Utility Model Registration No. 110067, registered date 1997. 09. 19. Applicant is the applicant) is a shape in which the heating wires 2 of a single line are arranged in parallel.

The heating element of the single wire structure has a defect in that the heating wire of the outer strand breaks well due to repeated bending and unfolding of the heating wire in use in a place with a high cushion such as a bed mattress.

The present invention intends to increase durability by thinning a heating wire of a single wire and double-folding in multiple layers.

For example, heating wires commonly used in conventional weaving heating elements can be connected in parallel with dozens to hundreds of strands in line with ultrafine wires of around 0.15 mm in diameter (61 Ω resistance per 1 M for nickel chrome). In the case of use in places with heavy cushions such as bed mattresses, the heating wires have been repeatedly bent and unfolded, and the heating wires are easily broken.

The fruit material of the present invention doubles the heating wire (2) of the single wire to extend the life of the heating wire to multiple times, not one time at the time of the disconnection,

Since the wire diameter is made finer and several strands are used in a single strand, it is intended to improve the functionality for bending by further enhanced flexibility.

In other words, when a heating wire of 0.15mm thickness used as an outer strand is replaced with a heating wire (3) of double strands in which nine strands of wire diameter of 0.05mm (resistance value per 1M for nickel chrome is 550Ω) Both objects have the same resistance value, but the flexibility and durability of the heating element (3) of the double track is extremely extended.

The structure of the heating wire (2) used in the woven heating element (Utility Model Registration No. 110067) is composed of a heating wire (3) of a double wire stranded by several strands.

As the heating wire used is doubled, it is an excellent design that the flexibility and durability of the heating wire are further extended.

Claims (1)

A plurality of metal heat generating thin wires are gathered in one strand to form a heating wire 3 of a double wire, and a plurality of heat generating wires 3 of the double wire are conductive wires 5 which are thin wires. In addition, a weaving heating element having a double wire structure is provided in which the heating wire is connected in parallel by orthogonally weaving a predetermined portion of the weaving machine, and the conductive wire 5 is used as a connection line of the power source.
