The present invention relates to a debris filtering device of a washing machine, and more particularly, by providing a debris filtering device of a washing machine to filter foreign materials in the washing water in the washing tank of the washing machine so as to be submerged in the washing water, The present invention relates to a foreign material locking device of a washing machine that improves the filtering performance of a foreign material and prevents damage of a jam filter caused by contact with laundry.

Conventionally, in the washing tank of the washing machine, a foreign material catching device for filtering foreign matter in the washing water was provided.

In other words, for example, it is provided with a water channel through which the upper and lower surfaces communicate with one side of the washing tank, and the upper portion of the washing tank allows the detachable foreign matter filter to remove various foreign substances contained in the washing water. It was provided.

Therefore, the washing water stirred by the pulsator is pumped upward along the water channel by the stirring force thereof, and passes through the filtering filter, so that various foreign substances such as seams and times generated during the washing process are repeatedly contained in the washing water. Foreign matter was filtered out of the filter.

However, since the conventional configuration as described above is a configuration in which the stirring force by the pulsator located in the lower portion is configured to pump the washing water to the uppermost side through the water channel, the whole washing water in the washing tank evenly passes through the filter due to the lack of pumping force. It was difficult to have a problem that the performance is reduced, and moreover, foreign matter that could not be suspended due to the lack of agitation of the wash water could not be pumped along the waterway, and had a problem of being left in the washing tank as it is.

In addition, since the filter is provided in the upper side, i.e., on the surface of the water while being exposed in the tub, the filter is rotated with the washing water during washing and rinsing, and the filter is easily damaged by direct contact with the floating laundry. .

Therefore, the present invention has been devised in view of the above-described conventional technical defects, and improves the foreign matter trapping performance while preventing the jam filter from being damaged by contact with the laundry rotating together with the washing water during washing and rinsing administration. The object is to provide a foreign material filtering device of a washing machine.

In order to achieve the above object, the present invention is to provide a foreign matter filtering means in place of the washing tank of the washing machine, wherein the foreign matter filtering means is formed on the inner wall surface of one side of the lower part of the washing tank so as to form a space portion spaced apart from the inner wall surface of the washing tank. Is provided with a fastening member for guiding a part of the wash water forced to circulate through the space portion by the rotational force of the pulsator, the removable member is provided on the upper portion of the fastening member and the filter member is provided with a filter for filtering foreign matter inside Provided is a foreign material filtering device of a washing machine.

Next, a preferred embodiment of the present invention for achieving this purpose will be described in detail with reference to the accompanying drawings.

1 is a schematic configuration diagram showing a configuration of a washing machine to which the present invention is applied, and reference numeral 1 in the drawings is a washing machine body.

The washing machine 1 is composed of a water tank 2 in which a certain amount of washing water is fresh, a washing tank 3 provided in the water tank 2, and a pulsator 4 provided in the washing tank 3 to stir the washing water. In addition, a driving unit 5 for selectively driving the washing tank 3 and the pulsator 4 in the washing tank 3 is provided at the bottom of the water tank 2, and at one side of the water tank 2 is over. The flow pipe 6 is provided.

It has the same configuration as in the prior art, but in the present invention is provided with a foreign matter filtering means 10 for filtering foreign matter in the wash water on one side in the washing tank (3), as shown in FIG. 3) is composed of a fastening member 20 which is fastened and fixed to one side wall in the inside, and a filtering member 30 provided with a detachable upper end of the fastening member 20 and having a foreign material filtering filter 31 therein.

That is, the fastening member 20 is fastened to one side in the washing tank (3) as a fastening bolt 23 is screwed through the locking projection 21 of the lower portion and the fastener 22 of the rear, it is fixed inside Prize. At the same time as having a water channel 24 communicated with the lower portion, the upper and lower portions of the water channel 24 are provided with an inlet port 25 through which the washing water in the washing tank 3 flows and a discharge port 26 through which the washing water is discharged.

In addition, the upper portion of the fastening member 20 is provided with a fastening hole 28 at the upper end thereof having a step 27 to which the filtering member 30 to be described later is fastened.

In addition, the filtering member 30 has a rear opening and a plurality of discharge holes 32 are provided at the front, and at the same time, a guide passage 33 corresponding to the outlet 26 of the fastening member 20 is formed at the upper portion thereof. The filter 31 is integrally coupled to the guide passage 33 thereof, and the fastening protrusion 34 is inserted into and fastened into the step 27 of the fastening member 20 to the bottom of the filtering member 30. ) And at the same time the upper end is provided with a hook 35 that is inserted into the fastening hole 28 of the fastening member 20 described above.

Therefore, the present invention configured as described above is provided to be positioned under the center of the washing tub 3, that is, in the water of the fresh water to be washed. When explaining the effect thereof in detail, the fastening member 20 has a lower locking protrusion ( 21) is pressed into the hole formed in the bottom surface of the washing tub 3, the upper part is in close contact with the inner wall of the washing tub 3, and the fastening bolt 23 is screwed to the fastener 22 to fix it. The fastening protrusion 34 of the filtering member 30 is inserted into the fastening hole in the stepped jaw 27, and the upper hook 35 is inserted into the fastening hole 28 and fastened.

At this time, the hook 35 has elasticity of elastic material, and thus, the attachment and detachment of the filtering member 30 is easy. In addition, the guide passage 33 in which the filtering filter 31 is molded is discharged from the fastening member 20. 26).

Accordingly, the washing water stirred by the pulsator 4 during the washing process of the washing machine is lifted up through the water channel 24 while being sucked into the suction port 25 provided at the lower portion of the fastening member 20 by the stirring force thereof. It is discharged to the outlet 26 of the, the washing water discharged to the outlet 26 is guided to the guide passage 33 of the filtering member 30 is matched with this through the filter filter 31, the discharge hole in the front Through the 32 is to be circulated back into the washing tank (3), at this time, the foreign matter contained in the wash water in the process of washing water passing through the filter 31 will be filtered.

Meanwhile, as shown in FIGS. 3 and 4, the filtering filter 31 as described above has a fastening groove 36 in a state in which the fastening groove 36 is formed at the outer edge of the guide passage 33 of the filtering member 30. It may be provided with a removable filter 31 as a fastening bracket 37 through.

Therefore, the present invention has been made so that even if the rotational force of the pulsator acts only slightly under the center of the washing tank in which the wash water is desalted, that is, the water is easily circulated due to the agitated water stream. Even if a relatively large foreign material or a heavy foreign material that does not float to the top of the water is easily filtered by the filtering filter, and the entire washing water in the washing tank is circulated evenly to have the effect of improving the foreign matter filtering performance.

In addition, since the filter is embedded in the filter member and is not exposed to the outside, the filter may have an effect of being prevented from being damaged by direct contact with the laundry.
