The present invention relates to a washing machine, and more particularly, to improve the structure of the lead to improve the strength of the lead and to eliminate the phenomenon of water accumulation on the upper surface of the lid even if the lead is curved in consideration of the appearance.

In general, a washing machine is a product that removes various contaminants attached to clothes, bedding, etc. by using the emulsification of detergent, friction action of water flow caused by rotation of the pulsator, and impact action of the pulsator on laundry. Appearing automatic washing machine automatically performs a series of processes leading to washing, rinsing and dehydration without user intervention in the middle.

On the other hand, another type of washing machine is a drum type washing machine in which a washing machine is put into a drum provided in a horizontal direction to wash the laundry.

On the other hand, in general, a washing machine puts laundry into a washing tank while the lid is opened and inputs washing conditions through the key operation of the control panel. The washing water is opened while the water supply valve is opened, and the washing water is supplied to the washing tank. do.

Subsequently, while the motor is driven by the control of the controller, the rotational force is moderately decelerated and transmitted to the pulsator or the washing tank, and washing is performed. After the washing is completed, the washing tank is rotated at high speed and dehydration is performed by rotating the washing tank at high speed. The series of laundry processes is completed.

Meanwhile, recently, transparent lids are also applied to washing machines so that the reliability of the product can be checked by seeing the inside of the washing tank during washing and dehydration.

In other words, by making the lid of the washing machine transparent, the user can check the washing and dehydration progress visually from the outside without opening the lid so that the reliability of the product can be achieved.

However, in the transparent lid structure configured to see the inside of the washing tank, the thickness of the lid becomes thick, so that the transparency falls.

Therefore, there is a limit to bringing the thickness of the lead thickly, which causes the lead edge to collide with the lead supporting surface of the top cover every time the lid is closed, resulting in a breakage of the lead as a lot of impact is applied to the lead edge. do.

In other words, the edge of the lead (that is, the edge of the lead) is a site that is directly impacted by hitting the top cover when the lid is opened and closed.

On the other hand, in the conventional washing machine, the upper surface of the lid is flat and there is no external appearance.

Accordingly, when the surface is treated in consideration of appearance beauty, when water drips or splashes from the laundry on the upper surface of the lid, the problem of accumulation on the upper surface of the lid occurs.

The present invention has been made to solve the above problems, to improve the lead structure of the washing machine to improve the strength of the lead, and even if the lead surface is treated in consideration of the appearance of the water so that the phenomenon of water accumulation on the upper surface of the lid can be eliminated Its purpose is to.

In order to achieve the above object, the present invention includes a main body, a top cover mounted on the top of the main body, and a lead assembled to the top cover and the lead is caught on the lead support surface inside the top cover. In a washing machine; A lead cover is coupled to an edge region that extends over the top cover upper region of the lid, and the outline along the left and right directions of the washing machine at an arbitrary position in the front and rear directions of the washing machine of the lid and the lid cover coupled thereto is a fourth order curve. It is processed in the form, and the lead structure of the washing machine, characterized in that the drain hole is formed at the point corresponding to the lowest point of the curve.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to FIGS. 1 to 4.

1 is a perspective view showing the appearance of the washing machine of the present invention, Figure 2 is a longitudinal sectional view of the main portion along the line I-I of Figure 1, Figure 3 is an exploded perspective view showing a lead structure according to the invention, Figure 4 Is a contour view of the outline of the lid assembly of the present invention along the line II-II, which is an optional incision along the left and right directions of the washing machine.

The present invention includes a main body 1, a top cover 10 mounted on the top of the main body, and a lead 11 assembled to the top cover and having an edge on the lead support surface 100 inside the top cover. In a washing machine; A lid cover 11c is coupled to an edge region that extends over the upper region of the top cover 10 of the lid, and the left and right sides of the washing machine at an arbitrary position in the front and rear directions of the washing machine of the lid and the lid cover 11c coupled thereto. The outline along the direction is processed in the form of a fourth function curve, and the lead structure of the washing machine is provided, wherein a drainage hole 30 is formed at a point corresponding to the lowest point of the curve.                     

At this time, the outer side of the washing machine along the left and right direction is shown in the form of a fourth function curve, the central portion of the upper portion of the washing tank is convex upwards, the left and right outer side is convex downwards, and the convex upwards The point where the convex outer side meets each becomes the lowest point.

The lid 11 and the lid cover 11c may be made of a transparent material or an opaque material.

The lid 11 may be made of a transparent material, and the lid cover 11c may be made of an opaque material.

In addition, the lid 11 includes a lid rear plate 11a hinged to the top cover 10, a lid front plate 11b hinged thereto, and a user can open and close the lid 11. 2 and 3, the lid cover 11c also includes a lid cover rear plate 11c-a and a lid cover front plate 11c-b hinged thereto. Of course.

In addition, on the flange surface 110 of the edge of the lead cover 11c is joined to the hook 113 formed on the flange surface 112 of the lead edge and the surface 116 facing the flange surface 112. The hook fastening hole 110a is formed to allow the lead cover 11c to be coupled to the lead 11.

Hereinafter, the washing machine and the action of the present invention will be described.

According to the present embodiment, as the lid cover 11c is coupled to the edge of the lid 11, the strength of the lead is improved.                     

That is, the reinforcement of the lead edge is made by the lead cover 11c, so that the overall strength of the lead to which the lead cover is coupled is improved.

In particular, as the reinforcement of the lead edge is remarkably improved by the lead cover, it is possible to prevent the lead edge breakage due to the collision with the top cover 10 generated when the lid 11 is closed.

On the other hand, in the present invention, when the washing machine is cut along the left and right directions at an arbitrary position in the front and rear directions of the washing machine of the lid 11 and the lid cover 11c coupled thereto, the outline of the lid and the lid cover is fourth order. Processed in the form of a function curve, the drain hole 30 is formed at a point corresponding to the lowest point of the curve (that is, the inflection point on the left and right sides).

Accordingly, the lid 11 of the present invention is curved so that the water dropped on the upper surface of the lid while being aesthetically improved is dropped into the washing machine through the drainage hole 30 and then discharged to the outside through a drain hose (not shown). The phenomenon of water sticking on the upper surface is effectively prevented.

In other words, the present invention can minimize the lead edge breakage caused by hitting the lead support surface 100 of the top cover 10 as the lead 11 is opened and closed by improving the strength of the lead edge region, the lead top surface Due to the prevention of water trapping, it is possible to improve the product reliability of the washing machine.
