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

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

２ At the left and right ends of the first column 53, a second column 54 is provided so as to extend upward. The second cylinder 54 forms a U-shape (U-shape) integrally with the first cylinder 53. The “U-shape (U-shape)” includes not only a case where the U-shape is completely (U-shape) but also a case where the U-shape is substantially (U-shape). A plurality of first cylinders 53 and second cylinders 54 forming a U-shape (U-shape) are arranged at predetermined intervals, and are arranged over the entire central portion 55 in the longitudinal direction. . Thus, the central portion 55, the first column 53, and the second column 54 constitute a rib-like structure as a whole. As described above, the first column 53 extends in the horizontal direction (left-right direction) from the center portion 55. The first column 53 may be inclined upward (vertically) as the distance from the center portion 55 increases. The second cylinder 54 extends upward from the tip of the first cylinder 53.

The rib 56 is formed in the longitudinal direction of the center part 55 and is located on the center line of the center part 55. The rib 56 extends upward. The rib 56 has a role of rectifying the flowing water and a role of ensuring the strength of the filter unit 52.

Next, the operation and function of the present invention will be described with reference to FIGS. 5, 6A and 6B.

FIG. 5 is a schematic view showing the flow of the washing water in a state where the filter member is attached to the case member of the washing machine. FIG. 6A is a schematic diagram illustrating a state in which a filter unit of the washing machine has collected foreign matter. FIG. 6B is a schematic view showing a state in which foreign matter is removed from the filter unit of the washing machine.

時 When the water in the water tank 11 is drained, the drain cock 18 is opened. Then, the washing water in the water tub 11 flows into the case inflow path 61 via the drain pipe 19 and reaches the filter section 52 mounted inside the case member 60. The washing water passes through the filter section 52 as shown by the arrow B in FIG. 5, and is discharged to the outside through the case discharge path 62 and the drain hose 35.

On the other hand, when using the circulation pump, the drain cock 18 is closed. When the circulation pump 21 is operated, water is sucked from the circulation pump connection part 63 by the operation of the circulation pump 21 and is sent to the filter part 52. After being sent through the filter section 52, the fed washing water passes through the circulation pump connection section 63 as shown by the arrow C in FIG. In this way, by circulating the washing water after being filtered by the filter unit 52, it is possible to increase the washing capacity while suppressing the amount of water used.

As described above, the foreign matter 70 contained in the washing water is collected by the filter unit 52 regardless of whether it is draining or using a circulation pump. Specifically, the washing water that has fallen from above the tip of the center 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 the first cylinder 53. It is discharged outside through the gap between the adjacent first cylinders 53. The foreign matter 70 such as lint or hair passes through the gap between the adjacent second cylinder 54 and the second cylinder 54 or the gap between the adjacent first cylinder 53 and the first Of the first cylinder 53 or the first cylinder 53. Leaving the foreign matter 70 causes mold and unpleasant odor. Therefore, if a certain amount of foreign matter 70 accumulates in the filter part 52, the filter part 52 needs to be cleaned.

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

First, the user opens the second door body 45 and takes out the filter member 50. As described above, the filter member 50 can be removed from the case member 60 by rotating the grip portion 51 in a predetermined direction to release the lock, and pulling the filter portion 50 toward the user. 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 above-described predetermined direction.

Subsequently, the foreign matter 70 collected by the second cylinder 54 or the first cylinder 53 is traced upward with nails, fingertips, 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 only by tracing upward, and the foreign matter 70 can be easily collected from the end of the second cylinder 54. Can be removed.

If the foreign matter 70 cannot be completely removed by merely tracing upward, a water flow may be added from the back surface of the first column 53. By applying a water flow from the back surface of the first cylinder 53, the foreign matter 70 moves along the second cylinder 54, so that it is possible to remove fine foreign matter 70 that could not be removed only by tracing.

{Circle around (4)} When the foreign matter 70 wraps around the central portion 55, it is difficult to remove the foreign matter 70 only by tracing upward. However, since the ribs 56 are formed on the central portion 55, it is possible to prevent the foreign matter 70 from being collected so as to wind around the central portion 55. For example, even if the foreign matter 70 is wrapped around the central portion 55, a gap is formed between the central portion 55 and the rib 56, so that the foreign material 70 can be cut and removed with scissors.

In the present embodiment, since the first column 53 is provided at the bottom of the filter section 52, the foreign matter 70 can be collected also at the bottom. Further, since the water flow passes through the bottom through the gap between the adjacent first cylinders 53, the drain flow rate can be secured.

In addition, the water flow that has flowed into the inside of the filter unit 52 is divided into right and left so as to avoid the ribs 56, and the adjacent second cylinder 54 and the second cylinder 54 or the adjacent first cylinder 53 and the first cylinder It is discharged out of the gap 53. This suppresses the generation of the vortex water flow in the central portion 55, and further reduces the resistance that water receives from the filter.

As described above, the drum type washing machine in the present embodiment includes the main body 1, the water tub 11 supported by the main body 1, the rotating drum 10 disposed in the water tub 11, and provided rotatably, A drain pipe 19 and a drain hose 35 for discharging the water discharged from the drain 11 to the outside, a case member 60 provided in the middle of the drain pipe 19 and the drain hose 35, and detachably housed in the case member 60; And a filter member 50 that collects foreign substances 70 contained in the water to be collected. The filter member 50 has a central portion 55 extending in the longitudinal direction of the filter member 50, and a plurality of side portions extending in a U-shape around the central portion 55.

Accordingly, the foreign matter 70 collected by the filter member 50 can be removed from the side by simply tracing upward. Therefore, the filter device for filtering water can be easily cleaned, so that the filter device can be easily maintained.

The filter member 50 may have a rib 56 provided in the longitudinal direction of the center portion 55, and the rib 56 may extend upward.

Thereby, the generation of the vortex water flow in the central portion 55 is suppressed, and the resistance that the water receives from the filter can be reduced. Therefore, it is possible to suppress a decrease in the speed of the water flow in the filter member 50.

側 Further, the side portion is composed of the first columnar member 53 and the second columnar member 54. The first columnar member 53 extends horizontally from the center portion 55. The second columnar member 54 extends upward from the tip of the first columnar member 53. Further, a plurality of first columnar members 53 and second columnar members 54 are provided.

Accordingly, the foreign matter 70 collected by the filter member 50 can be removed from the end of the second columnar member 54 only by tracing upward.

The first cylinder 53 is inclined upward as the distance from the center portion 55 increases.

(4) As a result, the foreign matter 70 accumulated on the central portion side is pulled in the left-right direction along the first columnar member 53, so that the foreign matter 70 is easily pulled along this inclination. As a result, the foreign matter is easily transferred from the first columnar member 53 to the second columnar member 54 smoothly. Therefore, the foreign matter 70 collected by the filter member 50 can be more easily removed from the end of the second columnar member 54 only by tracing upward.

Note that, in the description of the present embodiment, the description has been made using words indicating directions such as “horizontal direction” and “vertical direction”. , And "substantially vertical" directions.
