The present invention relates to a foreign body collecting structure of a washing machine, and more particularly, to prevent leakage and backflow near the strainer bag so as to efficiently collect foreign substances generated when washing laundry as a strainer bag installed in a balancer of the washing machine. will be.

In general, a washing machine is a product for removing various contaminants attached to clothes, bedding, etc. by using the emulsion action of the detergent and the friction action of the water flow due to the rotation of the pulsator and the impact action of the pulsator on the laundry. By detecting the amount and type of the laundry by the sensor, the washing method is automatically set, the washing water is supplied to the appropriate level according to the amount and type of the laundry, and the washing is performed under the control of the microcomputer.

In the conventional fully automatic washing machine, as illustrated in FIGS. 1 and 2, an outer tub 2 for storing wash water is installed inside the main body 1 forming an outer appearance, and power is applied to an outer bottom of the outer tub 2. Receiving and driving the motor 3 is installed, the outer bottom of the outer tub (2) receives the driving force from the motor (3) via the belt (4) through the clutch for driving a pulsator or laundry dehydration tank to be described later ( 5) is mounted, the inside of the outer tub (2) is combined with a washing dehydration tank (6) rotatably mounted to dehydrate the laundry by centrifugal force due to the rotation of the clutch (5).

In addition, a balancer 7 for maintaining a horizontal state of the combined laundry dehydration tank 6 is installed on the upper side of the combined laundry dewatering tank 6 so that the laundry rotates even when the laundry is depressed to one side. On the bottom surface of the tank 6, a pulsator 8 is rotatably installed on the bottom surface of the main body 1 to form a water stream in the wash water contained in the combined washing and dehydration tank 6 to perform washing. The water supply means 9 which detects the water level of the wash water stored in the outer tank 2 by a detection apparatus (not shown) and supplies the wash water according to the laundry in the outer tank 2 is provided.

In addition, a drainage means 10 for discharging the contaminated washing water generated at the time of washing and rinsing is installed at one lower side of the outer tub 2, and inside the combined washing and dehydrating tank 6 of the pulsator 8. A guide tube 11 for guiding the water flow upward as the rotation is provided.

In addition, the inner side of the balancer 7 coupled to the end of the guide tube 11, as shown in FIG. 2, the raised water flow guided through the guide tube 11 to the inner center of the combined washing and dehydration tank (6). A discharge port 12 is formed to discharge to form a waterfall water stream, and a filter bag bag 13 for filtering foreign matters of the laundry flowing by the raised water stream is disposed below the discharge port 12.

In the conventional fully automatic washing machine configured as described above, laundry and detergent are put in the washing / drying dehydration tank 6, and operation conditions are selected by an operation unit (not shown), and then the washing machine is operated. When the washing water is supplied to the inside, and the washing water supplied to the outer tank 2 reaches the necessary amount for washing the laundry put into the washing / drying dehydration tank 6, the motor 3 starts to rotate. At this time, the rotational force of the motor 3 is transmitted to the clutch 5 through the belt 4, the clutch 5 receives the rotational force of the motor 3 to decelerate and then rotates the pulsator 8 to dehydrate the combined use of washing. The water is stored in the tank 6 to form a stream of water to perform washing.

That is, as the pulsator 8 rotates, the washing water introduced into the combined washing / dehydration tank 6 rises at the edge of the pulsator 8, and the upstream and downstream water flows down to the center of the pulsator 8. It is formed to proceed with the washing.

On the other hand, by the rotational force of the pulsator (8), the bottom water flow of the washing and operation dehydration tank (6) is pushed toward the inner surface of the washing and operation dehydration tank (6), and after rising along the guide pipe (11), the balancer (7) Through the discharge port 12 and the strainer bag 13 formed on one side of the pour into the inner central portion of the combined use dehydration tank (6) to increase the washing effect, the strain filter the laundry by the strainer bag (13) You lose.

Then, when the washing is finished, the solenoid valve (not shown) installed in the lower part of the outer tank 2 is turned on (opened), and the contaminated washing water stored in the outer tank 2 and the combined washing / dehydration tank 6 is drained. It is discharged to the outside through the means (10).

Then, when the drainage of the wash water is completed, the solenoid valve is turned off and the rinsing wash water is supplied to the inside of the outer tub 2 through the water supply means 9 to reach the level required for rinsing the laundry. According to the driving force of the clutch 5 which has received the driving force of the motor 3, the pulsator 8 rinses the contaminants and detergents that ooze in the laundry while repeating the clockwise and counterclockwise rotations.

When the rinsing stroke is finally completed by repeating the above rinsing cycles a plurality of times, the rinsing-completed wash water stored in the outer tank 2 and the combined washing / dehydrating tank 6 is discharged through the drainage means 10 to the outside. In this case, the washing combined dehydration tank 6 rotates in one direction according to the driving force of the clutch 5 to dehydrate the washing water in the combined washing dehydration tank 6 and the washing water permeating the laundry.

On the other hand, such a conventional washing machine, as shown in Figure 2, when the strainer bag 13 is installed in the balancer 7, in the state that the strainer bag 13 is preferentially inserted into the filter case 15 By assembling and coupling the filter case 15 to the balancer 7, the foreign matter contained in the wash water pumped at the washing stroke is filtered out as the strainer bag 13.

However, since the filter case 15 and the balancer 7 are simply assembled in a sealed type using the minimum size of the assembly gap Gap, an extra dimension caused by the assembly gap is generated and pumped along the guide tube. As water leakage and backflow occur, the efficiency of collecting foreign matter on the strainer bag 13 decreases, and when such a long-term use is used, the surrounding foreign matter dries up and becomes dirty, which makes it impossible to proceed with washing in a clean state at all times. There were many problems such as.

The present invention is to solve the above problems, by preventing leakage and heat flow near the strainer bag installed in the balancer of the washing machine can not only efficiently collect foreign substances generated when washing laundry, but also due to the efficient collection of foreign substances It is an object of the present invention to provide a foreign body collecting structure of a washing machine that can wash laundry in a clean state at all times.
