Abstract

In the construction of a drying tub's drain strainer in a double tubs washing machine, the drain strainer whose lower part is formed cylindrically, is inserted into the drain hose which is fitted onto two poles formed on the drying tub. The lower part of the drain strainer has a groove which is connected with a circular projection, thereby preventing a floating of the drain strainer caused by a backward flow or a vortex flow of water.

Detailed description of the invention

(Field of invention)

The present invention relates to a two tank type washing machine.

The present invention relates to a structure of a drain strainer installed in a natural drainage system and a forced drainage system of a two tank type washing machine.

(Background of invention)

The drainage strainer of the dewatering tank of the two-chamber washing machine has been used in the lower part of the dewatering tank in the form of a circular filter like FIG. However, this drainage strainer is suspended in the upper direction by the backflow or vortex of the washing water in the washing machine of the general type or the washing machine of the pump type in which the washing water is drained by the forced drainage method. The solid wastes present were introduced into the drainage pump through the drainage hose, resulting in the impairment of the impeller. In order to eliminate such drawbacks, it has led to the development of a cylindrical drainage strainer that can be inserted and installed along the drainage pipe of the bottom surface of the dehydration tank.

(Purpose of invention)

It is an object of the present invention to provide a drainage strainer capable of preventing the drainage strainer from floating in the upper direction due to the backflow or vortex of the wash water in the drainage strainer of the dewatering tank of the two-chamber washing machine.

Another object of the present invention is to provide a drain strainer that can prevent the conventional drain strainer is suspended in the upper direction and the solid residues are introduced into the drain pump to damage the impeller.

(Summary of invention)

The present invention has a cylindrical structure in a two-type washing machine dewatering tank of a natural type that is naturally drained to a two-type washing machine dewatering tank of a drain strainer and a drainage strainer forming a groove around the cylindrical shape to be inserted into the lower projection of the drain pipe. It relates to a drainage strainer having a cylindrical structure. Since the drain strainer of the present invention is inserted into the drain pipe fixed to both sides of the upper part of the drain pipe and installed into the drain pipe, it is possible to prevent the drainage strainer from floating due to backflow or vortex of the wash water. Hereinafter, with reference to the accompanying drawings will be described in detail.

(Explanation of specific example of invention)

As shown in FIG. 1, the drain pipe 2 mounted in the dewatering tank 1 of the two-chamber washing machine is placed with the drain strainer 6 shown in FIG. However, the drain strainer 6 may float in the upward direction due to backflow or vortex of the wash water. Drain strainer (6) serves to filter lint, solid debris, etc. that may be present in the wash water, the solids such as debris by floating in the upper direction as it is along the drain pipe (2) (not shown) It will get inside and damage the impeller.

Of course, in the drainage of the washing machine drained by the drainage pump, as shown in FIG. 1, a cylindrical protrusion 3 is formed around the cylindrical inner portion of the drainage pipe 2, and the backflow prevention plate 4 is attached to the portion. . Even when the non-return plate 4 is attached, a slight backflow occurs, so that the drainage strainer 5 floats.

In the present invention, the same type of drainage strainer 7 as shown in FIG. 3 is inserted into a two-type washing machine of a pump system in which the backflow prevention plate 4 is formed, thereby preventing the drainage strainer 7 from being floated due to filtration or vortex of the wash water. The upper portion of the drain strainer 7 has the same filter function as the conventional drain strainer 6, and a lower portion formed in a cylindrical shape is inserted into the drain pipe 2. Shown in FIG. 5 is a cutaway view showing a state where the drain strainer 7 is inserted into the drainage device located on the lower surface of the dewatering tank.

In addition, the drainage strainer 8 as shown in FIG. 4 is inserted into the two-type washing machine of the general type in which the backflow prevention plate 4 is not formed to prevent the drainage strainer 8 from being oiled. A groove 9 is formed along the circumference of the drain strainer 8 so as to couple the groove 9 to the circumferential protrusion 3 of the drain pipe 2.

The drain strainers 7 and 8 may be inserted into the inner side of the two poles 5 mounted in the dehydration tank 1 to effectively prevent the floating phenomenon.

Although the invention has been described in detail only with respect to the described embodiments, it will be apparent to those skilled in the art that various modifications or changes can be made within the spirit and scope of the invention and therefore such variations and modifications are within the scope of the appended claims. Do.
