Referring to Figure 4, the lead structure according to the present invention is manufactured by the insert injection method as described above.

In detail, the lead body 210 made of a transparent material is inserted between the upper mold 300 and the lower mold 310, and then the resin 320 is introduced through the injection hole 330.

Here, an injection space having the same shape as that of the lead cover 220 is formed in the upper mold 300 and the lower mold 310.

Meanwhile, when the resin mixture 320 injected through the injection hole 330 is solidified, the lead structure is completed by separating the upper mold 300 and the lower mold 310.

Figure 5 is a vertical cross-sectional view formed along the line A-A of Figure 3, Figure 6 is a cross-sectional view showing a state that the reinforcement cover is attached to the lower side of the lead cover.                     

5 and 6, in the lid 200 according to the present invention, a lid cover 220 made of a plastic resin material is enclosed around the lead body 210 of glass material. In addition, a plurality of valleys are formed on the bottom surface of the lead cover 220. This is to prevent the shape of the lead cover 220 from being deformed when the resin is solidified by reducing the thickness of the lead cover 220 when inserting the insert. Then, the protruding surface formed between the bone and the bone is a fusion surface in contact with the lead reinforcement cover 230 which will be described later.

On the other hand, the lead reinforcement cover 230 attached to the lower side of the lead cover 220 is attached to reinforce the strength of the lead cover 220, the lead cover 220 by the vibration welding or ultrasonic welding method Is glued with.

Here, the vibration fusion method is a method in which the two fusion surfaces are melted and the two fusion surfaces are melted and re-molecule-bonded and then bonded through a hardening step. In addition, the ultrasonic fusion method is a method in which, as in the vibration fusion method, by applying ultrasonic vibration in a state where two objects are in contact with each other, the contact surface is melted to bond the two objects.

In detail, the lead reinforcement cover 230 is formed with a covering part 231, the inner end portion is curved to extend, and the fusion surface 232 in contact with the fusion surface 221 of the lead cover 220. When the fusion surfaces 221 and 232 are in contact with each other and are subjected to vibration or ultrasonic waves, the fusion surfaces 221 and 232 are melted and recombined by intermolecular attraction. When the fusion surfaces 221 and 232 are hardened, the lead cover 220 and the lead reinforcement cover 230 are strongly bonded to be integrated.

In more detail, when the lead cover 220 and the lead reinforcement cover 230 are bonded by vibrating fusion, fusion dregs are generated near the fusion surface by vibration. In addition, the debris does not fall off from the lid cover 220, so that the appearance is not neat. Therefore, in order to prevent the residue from being exposed to the outside, the residue covering part 230 which is formed by extending the inner end of the lead reinforcement cover 230 is formed.

Referring to FIG. 7, in order for the lead reinforcement cover 230 according to the present invention to be attached to the lead cover 220, the upper surface of the lead cover 220 and the bottom surface of the lead reinforcement cover 230 are pressed. Force (F) is acting. In other words, the force F is applied in the vertical direction so that the fusion surface 221 formed on the lower side of the lead cover 220 and the fusion surface 232 formed on the upper side of the lead reinforcement cover 230 are in strong contact with each other. When the lead cover 220 and the lead reinforcement cover 230 are strongly adhered to each other, vibration or ultrasonic waves are applied to the welding surfaces 221 and 232.

Here, when the force (F) applied to the fusion surface 221, 232 penetrates through the lead body 210, there is a risk that the lead body 210 is damaged. Therefore, it is preferable that the formation positions of the fusion surfaces 221 and 232 are selected so that the action line to which the force F is applied does not pass the lead body 210.

As shown, the upper and lower surfaces of the lead cover 220 and the lead reinforcement cover 230 are formed by forming the fusion surfaces 221 and 232 at positions spaced apart from the lead body 210 by a predetermined distance. The pressing force F is not applied to the lead body 210.

By the lead structure of the washing machine according to the present invention having the above configuration, the lead reinforcement cover is attached to the lower side of the lead cover, thereby increasing the strength of the lead cover.

Further, the lead body is damaged during the fusion process for joining the lead cover and the lead reinforcement cover by preventing the pressing force acting on the fusion surface formed on the lead cover and the lead reinforcement cover from acting on the lead body. There is no effect.
