Description

Filter device of washing machine

The present invention relates to a filter device of a washing machine, and more particularly, to a filter device of a washing machine which prevents the filter from being leaked due to water pressure by improving the installation structure of the filter device installed in the lower part of the washing machine.

1 is a schematic cross-sectional view of a conventional washing machine, in which a rectangular main body 1 and a water tank 2 in which a predetermined amount of washing water is freshly suspended are installed inside the main body 1 by a hook rod 7. .

In addition, the cylindrical washing tank 3 is installed inside the water tank 2 in a rotatable state.

Washing tank (3) is formed a myriad of holes (3a) penetrating the side wall to flow the washing water supplied into the washing tank 3 toward the water tank (2) to match the water level of the washing tank (3) and the water tank (2) In addition, these holes (3a) discharges the washing water generated from the wet feeling in the dehydration process toward the water tank (2).

On the other hand, the stirring blade (4) is installed on the inner bottom of the washing tank (3) to enable reverse rotation. Stirring blade (4) is to be rotated forward and reverse in the washing process, to stir the wash water supplied into the washing tank (3) to produce a rotary water flow.

In addition, a power switching means 6 which is rotated by the motor 5 is installed at the center of the bottom surface of the water tank 2. The power switching means 6 has a washing shaft (6a) and a dehydration shaft (6b) is formed on the upper side, the washing shaft (6a) is combined with the stirring blade (4) and the dehydration shaft (6b) on the bottom of the washing tank (3) Combined.

And the filter device 10 is installed on one side lower portion of the main body 1 and the watering pipe (8) for sprinkling the wash water into the washing tank (3) is formed on the top of the water tank (2).

In addition, the bottom of the water tank (2) and the filter device 10 is connected to the hose (9b), the pump 9 is installed between the filter device 10 and the water pipe (8), the drain valve behind the pump (9) (9a) is installed to drain the wash water during dehydration.

In the conventional washing machine configured as described above, washing is carried out in a state in which laundry is contained in the washing tub 3 and the washing water is supplied.

When the motor 5 is reversely rotated in the washing process, the rotational force thereof is transmitted to the power switching means 6, and the speed is reduced by the power switching means 6, and then the rotational force is transmitted to the stirring blade 4 through the washing shaft 6a. do.

At this time, when the stirring blade 4 is rotated forward and reverse, the washing water causes a rotational water flow and the washing progresses while the laundry is rubbed against each other by the rotational water flow.

In addition, during the washing process, a part of the washing water is pumped toward the sprinkling pipe 8 above the washing tank 3, and the pumped washing water is sprayed into the washing tank 3. That is, when the pump 9 is operated, the wash water is filtered through the filter device 10 through the hose 9b connected to the bottom of the water tank 2, and then the pumped wash water is pumped toward the water spray pipe 8 and the pumped wash water 3 ) Washing is improved as it is sprayed inside.

After the washing is completed, the washing water is drained through the drain valve 9c, and then dehydration proceeds. When the motor 5 rotates at a high speed in the dehydration process, the washing shaft 6a and the dehydration shaft 6b are rotated together by the power switching means 6 at a high speed, and the washing tank 3 is rotated at a high speed.

Therefore, all the laundry water is removed, the process associated with all the laundry is terminated.

2 is a cross-sectional view of a conventional filter device for a washing machine, the filter box 10a having an inlet pipe 10b and an outlet pipe 10c formed on an inner side of a bottom surface of a washing machine body 1 and having the other side thereof; The filter 11, which is embedded in the box 10a, is filtered by the strainer 11b, and has a female threaded portion 11a formed at the front thereof, and a packing fitted along the circumferential surface in front of the filter 11. (13) and a cover 12 formed with a male screw portion 12a at the rear and a handle 12b at the front so as to be fitted corresponding to the female screw portion 11a.

In addition, the inlet pipe 10b and the outlet pipe 10c are connected through a hose 9b.

In the conventional filter device configured as described above, the filter 11 is fitted into the filter box 10a. At this time, the filter 11 is lightly pushed into the filter box 10a with the packing 13 fitted in the front circumferential surface of the filter 11.

Subsequently, when the male screw portion 12a formed at the rear of the cover 12 is inserted into the female screw portion 11a in front of the filter 11 and rotates in the screw locking direction using the handle 12b, the filter 11 front The packing 13 fitted on the circumferential surface is compressed to fix the filter 11 to the filter box 10a.

Then, when the wash water flows through the inlet pipe (10b), the foreign matter generated after washing in the strainer (11b) is filtered and the wash water is discharged to the hose (9b) again through the outlet pipe (10c).

The user separates the filter 11 from the filter box 10a at regular intervals, cleans the strainer 11b, and assembles and uses the filter in the same manner as described above to fully utilize the function of the filter device 10.

The filter device of the conventional washing machine as described above has a problem that the fixing of the filter box and the filter is fixed depending only on the compressive force of the packing, and is separated by the water pressure of the washing water flowing into the inlet pipe, thereby causing the washing water to leak.

Accordingly, the present invention has been made in view of the above problems, and provides a filter device for a washing machine which prevents the filter from being leaked due to water pressure by improving the installation structure of the filter device installed in the lower part of the washing machine. There is a purpose.
