Abstract

The present invention relates to a washing machine having a grinding stone attached to a drum. More specifically, the grinding stone is fixed to an inner tube perforated plate of the washing machine by a fastening member, and then the surface of jeans is discolored due to friction between the grinding stone and the jeans in the course of turning the jeans and water in the inner tube. Also, an amount of discharged sludge is minimized since the grinding stone has excellent durability so that there is no damaged part in the jeans by an impact. Thus, the washing machine provides an environmentally friendly method and is able to reduce discoloration costs since the grinding stone has a long lifetime.

Description

A washing machine having a grinding stone fixed on a drum {washing machine}

The present invention relates to a method and apparatus for discoloring a surface of a jeans due to friction between a grinding stone and a jeans in a process of rotating the grinding stone by inserting jeans and water into the inner tube after fixing the grinding stone by the fastening member on the inner perforating plate of the washing machine, The present invention relates to a washing machine equipped with a grinding stone on a drum so as to minimize the amount of discharged sludge and to reduce the cost of discoloration due to the long life of the grinding stone.

The latest trend in jeans is the "vintage jean" type, which is a retro product that emphasizes the partial discoloration of the pants or the old, worn-out feeling of the old, worn-out, Has been a favorite of many jeans.

Accordingly, there have been known a number of processing apparatuses for decolorizing and worn out jeans in which the jeans are formed of old wrinkles according to the consumer's preference and are also decolorized so that the appearance of the jeans becomes old and worn.

In order to discolor and worn out jeans, jeans manufacturers have used stone washing methods to discolor or polish the jeans in a way that the new garments are reworked and sold by special treatment such as dyeing on the fabrics so that they look old and faded.

On the other hand, the washing machine is provided with a drum formed of a perforated plate inside the outer tube and outer tube, and puts jeans, water, and pumice inside the drum and rotates to discolor.

More specifically, as shown in FIG. 1, the jeans, water, and volcanic stone are put into the drum installed in the outer cylinder, and then the jeans are decolorized by operating the washing machine for a predetermined period of time.

Therefore, a large amount of sludge is generated due to the nature of minerals called pumice, and the sludge is discharged together with water, and a large amount of sediment is accumulated in the sewage pipe and the wastewater treatment plant, and the cost for treating the sediment is frequently generated.

In addition, the use of a large amount of pumice causes problems such as damage to the washing machine and wear, and sludge or waste generated from a large amount of pumice.

Also, jeans and pumice rub together, and the pumice is worn out, so it gets smaller and needs to be replenished continuously.

That is, there is a problem that the loss due to the friction and impact between the blades is larger than the loss due to the friction between the jeans and the pumice, thereby increasing the cost of purchasing the pumper.

Also, when pulling out the jeans from the machine, it is necessary to shake the pockets of the jeans and the pockets that have entered the clothes, and the jeans are soaked in water that it takes a lot of time to shake off the pumice.

Korean Patent Application No. 2001- 0013090 "Jeans < / RTI >

In order to solve the above-mentioned problems, the present invention provides a drum having a durable pearl plate fixed to a drum made of a perforated plate in place of a pearl with low durability, thereby maximizing friction with jeans and preventing collision between the grinding stones, So that the work process for minimizing the amount of pumice in the jeans and wiping the pumice in the jeans can be omitted and the productivity can be improved.

According to an aspect of the present invention, there is provided a drum type washing machine comprising a drum, a drum, and a drum, to provide.

INDUSTRIAL APPLICABILITY As described above, the washing machine according to the present invention has the effect that the grinding stone can be fixed to the perforated plate of the drum so as to be removable by the fastening member, and the grinding stone can be exchanged when worn.

 In addition, since the grinding stone is fixed to the perforated plate of the drum and does not collide with the grinding stones during the decoloring process, there is no cracking due to the impact, so there is an effect of reducing the loss.

Therefore, the amount of sludge generated is reduced in the course of decolorization, and the process for shoveling out the pumice powder is omitted, thereby improving productivity.

In addition, the use of abrasive stones in place of imported pumice can reduce production costs.

BRIEF DESCRIPTION OF THE DRAWINGS The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention.

FIG. 2 is a perspective view showing a washing machine of the present invention, FIG. 3 is a perspective view showing a drum in a washing machine of the present invention, FIG. 4 is an exploded perspective view showing a grinding stone of the present invention, FIG. 6 is a cross-sectional view showing a state where the abrasive stone of the present invention is attached to the perforated plate. FIG.

In the washing machine of the present invention, a drum formed of a perforated plate is provided in an outer cylinder and an outer cylinder. The driving shaft of the drum is connected to a motor not shown in the figure to rotate the drum, a means for supplying water to one side of the drum, And an outlet for discharging water is formed.

The drum is made of a perforated plate by arranging a plurality of holes so that water and jeans are poured into the bottom of the drum while the water and the jeans are rotated.

A plurality of grinding stones are uniformly arranged in the holes of the perforated plate, and then fixed by a fastening member so as to be detachable and attachable.

A bolt is integrally formed on one side of the grind stone so that the bolt can be fixed to the hole of the perforated plate And a method of fastening and fixing the rear end of the projected bolt with a nut is mainly used.

In order to prevent the bolt and the nut from being corroded, it is preferable to use a stainless steel material.

In order to prevent the jeans from being damaged when the drum rotates, it is preferable that the grinding stone be formed into a spherical shape, a hemispherical shape or a plate shape so that the shape of the grinding stone is not angled.

In addition, the Washing Machine installs the outer lid cap and the drum lid on the outer and inner tubes.

If the outer tube lid is installed on the outer tube, the abrasive stone installed on the perforated plate of the drum is worn to facilitate the replacement work.

In addition, drum lid is installed on the drum, jeans and water can be easily inserted and removed, as well as the ability to facilitate the installation of grinding stone.

FIG. 7 is a cross-sectional view illustrating a washing machine according to the present invention. In the process of rotating the drum installed in the outer tube of the washing machine, the grinding stone installed on the perforated plate of the drum rotates while being fixed by the fastening member. The jeans and grinding stone are frictioned, so that the work of discoloration proceeds, but the grinding stone remains fixed and prevents collision with each other, thereby minimizing the amount of sludge so that it can be discolored in an environmentally friendly environment.

 8A and 8B are photographs showing a state in which the grinding stone is attached to the washing machine of the present invention.
