Description

Washing water filter unit of the washing machine

The present invention relates to a washing water filter device of a washing machine, and more particularly, to a washing water filter device of a washing machine, which is capable of varying the height of a strainer trapping foreign matters such as lint or the like contained in the washing water according to the washing water level. It is about.

In general, a washing machine is an agitated washing machine in which an agitator reciprocates from side to side with a vertical axis to create a special flow of water, and a vortex in which a pulsator performs strong washing by generating a strong flow of water by rotating it forward and backward at the bottom of the washing tank. Type washing machines, a vibrating washing machine for washing by vibrating the diaphragm at the bottom of the washing tank, and a drum-type washing machine for washing by rotating a drum formed with a plurality of small holes on a horizontal axis to a point.

Conventionally, in such a washing machine, the vortex type washing machine has a washing tank 11 fixedly installed in the main body 10 as shown in FIG. 1, and a driving motor 12 is mounted on the bottom of the washing tank 11. Inside the washing tank 11, a dewatering tank 13 which rotates at high speed according to the operation of the driving motor 12 to dehydrate the laundry is rotatably coupled, and a bottom of the dehydrating tank 13 of the driving motor 12 According to the operation, the pulsator 14 which washes by forming a water flow while rotating forward and backward is rotatably coupled.

The dewatering tank 13 is coupled to a strainer 16 for collecting foreign substances such as lint and the like contained in the wash water circulated into the circulation channel 15, and wash water is disposed on the bottom of the washing tank 11. The drainage means 17 which discharges to the outer side of the main body 10 is provided.

Therefore, when laundry is put into the dehydration tank 13 and the desired washing conditions are selected, an appropriate amount of washing water is supplied into the washing tank 11, and then the pulsator 14 is positively and inversely driven by the operation of the drive motor 12. Washing is performed by repeatedly rotating to form a stream of water.

After the washing is completed, the drainage means 17 operates to drain the wash water to the outside of the main body 10, and when the wash water is supplied again, several times of rinsing to wash the laundry is performed. When the dehydration is performed by rotating at high speed to separate the wash water contained in the laundry by centrifugal force, the washing is completed.

At this time, during washing or rinsing, foreign matters such as lint and the like are included in the wash water, and these foreign matters are collected in the strainer 16 while the wash water is circulated through the circulation channel 15.

However, such a washing water filter device of a conventional washing machine does not adequately correspond to the level of the washing water determined according to the amount of laundry as the height of the strainer is fixed to a certain height, so when the washing water level is low Since the pumping amount of the water is small, the removal rate of the foreign matter contained in the wash water is low, and thus, various problems such as foreign matters are adsorbed to the washed laundry have been inherent.

Therefore, the technical problem to be solved by the present invention, that is, the object of the present invention is to solve the problems of the technology for the conventional washing machine filter described above, washing the laundry so that the height of the strainer is appropriately variable according to the water level of the wash water It is to provide a washing water filter device of a washing machine that can increase the removal rate of foreign matter contained in the water, and further improve the washing power of the laundry.

The present invention for achieving the above object, the washing water filter device of the washing machine includes a dewatering tank having a circulation channel through which the washing water is circulated, and a filter body coupled to the lifting and lowering in the circulation channel, the filter body washing It includes a strainer for storing foreign matter in water.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention for achieving the above object will be described in more detail.

2 is an exploded perspective view showing a washing water filter device of a washing machine according to the present invention, Figure 3 is a cross-sectional view of the washing water filter device according to the present invention, the dewatering tank 20 having a plurality of dewatering holes (20a) The inner side is formed with a circulation channel 21 through which the washing water flows during washing and rinsing.

A balancer 22 is formed on the upper side of the circulation channel 21 to maintain balance during rotation of the dehydration tank 20, and a predetermined interval is formed between the upper end of the circulation channel 21 and the balancer 22. Formed.

And the filter body 30 which slides in the up-down direction between the balancer 22 is inserted in the circulation channel 21 inside.

The filter body 30 includes an inlet 31 through which washing water is introduced at a lower end thereof, and a filtering net 32 storing foreign matters such as lint and the like contained in the washing water is detachably coupled thereto.

When the washing water filter device of the washing machine according to the present invention configured as described above is pumped through the circulation channel 21 when the washing water introduced through the circulation channel 21 is washed or rinsed, the inlet 31 of the filter body 30 is opened. It is pumped through and stored in the strainer 32 to remove foreign matter such as lint.

At this time, when the amount of laundry is a small amount and the water level of the washing water is low, when the filter body 30 coupled to the circulation channel 21 is lowered, the height of the strainer 32 is positioned at the lowest position, and thus the water level of the washing water. It is possible to remove the foreign matter.

On the contrary, when the amount of laundry is large, the height of the washing water is high. At this time, by raising the height of the filter net 30 to increase the height of the strainer 32, it is possible to remove foreign substances due to the high water level.

As described above, according to the present invention, the height of the strainer is adjusted by varying the height of the filter body, so that it is possible to remove foreign matters such as lint and the like contained in the wash water corresponding to the level of the wash water. At the same time as the removal rate is increased, the washing power of laundry is improved.

Although the present invention has been described with reference to one embodiment illustrated in the drawings as an example, this is merely exemplary and various modifications and equivalent other embodiments will be possible to those skilled in the art.
