4(a) is a side view of the filter portion of the washing machine according to Embodiment 1, FIG. 4(b) is a top view of the filter portion of the washing machine, and FIG. 4(c) is FIG. 4(b). and FIG. 4(d) is a sectional view taken along line AA of FIG. 4(b).

A base 57 is provided on the back surface of the grip portion 51 . The central portion 55 is provided so as to extend from the base 57 and is formed in a plate shape so that the tip thereof is inclined upward.

The first cylinder 53 is formed so as to extend left and right from the central portion 55 with the central portion 55 as the center. The first cylinder 53 gently slopes upward from the central portion 55 to the other end.

Second cylinders 54 are formed at the left and right ends of the first cylinder 53 so as to extend upward. The second cylinder 54 is integrated with the first cylinder 53 to form a substantially U-shape. A plurality of substantially U-shaped first cylinders 53 and second cylinders 54 are arranged at predetermined intervals, and are arranged over the entire central portion 55 in the longitudinal direction. As a result, the central portion 55, the first column 53, and the second column 54 form a rib-like structure as a whole.

The rib 56 is formed in the longitudinal direction of the central portion 55 and positioned on the centerline of the central portion 55 . The ribs 56 have a role of straightening the flowing water and a role of securing the strength of the filter portion 52 .

Next, the operation and effect of the present invention will be described with reference to FIGS. 5 and 6. FIG.

FIG. 5 is a schematic diagram showing the flow of washing water in a state in which the filter member is attached to the case member of the washing machine, and FIG. FIG. 6(b) is a schematic diagram showing how foreign matter is removed from the filter portion of the washing machine.

When the water in the water tank 11 is drained, the drain cock 18 is opened. Then, the washing water in the water tank 11 flows into the case inlet passage 61 through the drain pipe 19 and reaches the filter portion 52 mounted inside the case member 60 . Washing water passes through the filter portion 52 as indicated by arrow B in FIG.

On the other hand, when using the circulation pump, the drain cock 18 is closed. When the circulation pump 21 is operated, the water is sucked from the circulation pump connection portion 63 by the operation of the circulation pump 21 and sent to the filter portion 52 . After passing through the filter portion 52, the washed water sent in passes through the circulation pump connection portion 63 as indicated by the arrow C in FIG. By circulating the filtered washing water in this way, it is possible to increase the washing performance while suppressing the amount of water used.

Foreign matter 7 contained in the washing water, whether in the case of drainage or in the case of using a circulation pump
0 is collected by the filter unit 52 . Specifically, the washing water dropped from above the tip of the central portion 55 moves to the right while moving to the right between the gap between the second cylinder 54 and the adjacent second cylinder 54 or between the first cylinder 53 and the second cylinder 54 . It is discharged to the outside through the gap between the adjacent first cylinders 53 . A foreign matter 70 such as lint or hair can get entangled with the second cylinder 54 or the first cylinder 53 when passing through the gap between the second cylinder 54 or the first cylinder 53 . If the foreign matter 70 is left unattended, it may cause mold or an offensive odor. Therefore, when a certain amount of foreign matter 70 accumulates in the filter portion 52, the filter portion 52 needs to be cleaned.

Next, a method for cleaning the filter member 50 and the action of the filter member 50 will be described with reference to FIG.

First, the user opens the second door 45 and takes out the filter member 50 . As described above, the filter member 50 can be removed by rotating the grip portion 51 in a predetermined direction to unlock it and pulling it forward. The removed filter member 50 can be locked by inserting it into the filter member mounting portion 65 and rotating it in a direction opposite to the predetermined direction described above.

Subsequently, the foreign matter 70 collected by the second cylinder 54 or the first cylinder 53 is traced upward with a fingernail, fingertip, or daily necessities such as a toothbrush. Since the second cylinder 54 and the first cylinder 53 are formed continuously, the user can easily collect the foreign matter 70 simply by tracing it upward, and remove the foreign matter 70 from the end of the second cylinder 54 . can be removed.

If the foreign matter 70 cannot be completely removed by simply tracing it upward, it is preferable to apply water flow from the back surface of the first cylinder 53 . By applying the water stream, the foreign matter 70 moves along the second cylinder 54, so that even the fine foreign matter 70 that cannot be removed by just tracing can be removed.

Further, if the foreign matter 70 is wrapped around the central portion 55, it is difficult to remove the foreign matter 70 only by tracing it upward. However, since the ribs 56 are formed on the center portion 55 , it is possible to prevent the foreign matter 70 from being caught so as to wind around the center portion 55 . For example, even if the foreign matter 70 winds around the central portion 55, the gap is formed between the central portion 55 and the ribs 56, so that the foreign matter 70 can be cut and removed with scissors.

In the present embodiment, by providing the first cylinder 53 at the bottom of the filter portion 52, the foreign matter 70 can be collected even at the bottom. In addition, since the water flow passes through the bottom portion through the gaps of the first cylinders 53, it is possible to secure the drainage flow rate.

Also, the water flow that has flowed into the inside of the filter portion 52 is divided into left and right so as to avoid the rib 56 and is discharged outside through the second cylinder 54 or the first cylinder 53 . As a result, it is possible to suppress the occurrence of vortex water currents in the central portion 55, and further reduce the resistance that water receives from the filter.

As described above, the drum-type washing machine according to the present embodiment includes main body 1, water tank 11 supported by main body 1, rotating drum 10 arranged in water tank 11 and rotatably provided, water tank A drain pipe 19 and a drain hose 35 for discharging the water drained from 11 to the outside, a case member 60 provided in the middle of the drain pipe 19 and the drain hose 35, and detachably stored in the case member 60. and a filter member 50 for collecting foreign substances 70 contained in the water. The filter member 50 has a central portion 55 extending in the longitudinal direction of the filter member 50 and a plurality of first cylinders 53 and second cylinders 54 extending in a U shape around the central portion 55 .

As a result, the foreign matter 70 collected by the filter member 50 can be removed from the end of the second cylinder 54 simply by tracing it upward. Therefore, since the filter device for filtering water can be easily cleaned, the ease of maintenance of the filter device can be improved.

Further, as in the present embodiment, the filter member 50 may have ribs 56 formed in the longitudinal direction of the central portion 55, and the ribs 56 may extend upward.

As a result, it is possible to suppress the occurrence of vortex water currents in the central portion 55, and further reduce the resistance that water receives from the filter. Therefore, it is possible to suppress a decrease in the speed of the water flow in the filter member 50 .
