  Further, the tip of the partition wall 14 serving as a handle is set close to the lid 5 with a gap S, and is set lower than the upper edge portion 6a of the lint repair box 6 by a minute gap T.

  About the lint capture means of the washing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the lint capture box 6 has a water inlet 7 and a water outlet 8 on the same surface, so that the lint capture box 6 can be disposed at the tip of the first drain hose 4. By providing the opening / closing operation mechanism 9 for the lid 5 disposed on the opposite side of the water port 8, the lint removal operation of the lint capturing box 6 can be configured on the user operation side 1 a side in front of the washing machine outer box 1. Operability is improved.

  Further, the discharged liquid discharged from the water tank 2 passes through the inner bottom portion 2 a of the water tank 2, passes through the first drain hose 4, is led from the water inlet 7 into the lint capturing box 6, and is discharged from the water outlet 8 side. However, at this time, since the height position of the tip 11a of the lint filter 11 is arranged at a height between the water inlet 7 and the water outlet 8, the discharged liquid flowing from the water inlet 7 to the water outlet 8 is surely provided. When the lint filter 11 passes through the lattice holes 24 of the mesh portions 12 of the lint filter 11 and the drain holes 22 of the vertical wall portion 23, the lint filter removes lint and foreign matters contained in the drainage liquid. 11 can be surely captured.

  Moreover, since the waste water in the lint capture box 6 is discharged from the water outlet 8 to the outside of the lint capture box 6 because the drainage liquid at a position higher than the inner surface lower surface height c of the water outlet 8 is discharged from the water outlet 8. The lint captured by the mesh portion 12 disposed at a position higher than the inner diameter lower surface height c of the water outlet 8 is immersed in the remaining water in the lint capture 6 until the water level reaches the inner surface upper surface height c or lower. It is possible to drain the water without fail, and when the lint filter 11 is taken out and cleaned, it can be easily cleaned without dripping water.

  Also, lint and foreign matter are captured in a space 21 formed by the lid 5, the lint capturing box 6, the mesh portion 12, and the partition wall 14, and the space 21 is filled with lint or foreign matter, or the lint filter is clogged. When this occurs, the drainage liquid overflows from the gap S in the upper part of the partition wall 14 and flows out to the rib 13 and passes through the water passage 25 of the gap M below the lint filter 11, so that the water passage is blocked. It is possible to drain the water from the outlet 8, and it is possible to prevent the drainage time from becoming long or the occurrence of abnormal drainage.

  Furthermore, the surface area of the mesh is increased by configuring the lattice holes 24 of the mesh portion 12 to the lattice holes 24 of the substantially stepped steps 12a, 12b, 12c and the drainage holes 22 in the vertical wall portion 23, Since the drainage effective area through which the drainage liquid passes increases at the same time, it is possible to prevent clogging at an early stage and prevent drainage from being performed, and to reduce the frequency of lint filter cleaning.

  The height of the partition wall 14 provided in the lint filter 11 is configured to be low by a dimensional minute gap T, and is set to be approximately the same height as the lint capture box 6, so that the filter is picked up by hand when cleaning. The attachment / detachment operation such as can be facilitated and workability can be improved, and when the lint capture box 6 is filled with drainage liquid during drainage, the lint filter 11 tends to rise due to buoyancy. However, the partition wall 14 can be prevented by hitting the lid 5.

  By setting the mesh size of the mesh portion 12 to about 5 mm to 7 mm, the amount of lint and foreign matter flowing out to the drain port side can be reduced as much as possible, and the problem of easily clogging can be prevented. In addition, by providing the wall-like ribs 16 on the outer peripheral portion of the mesh portion 12, when removing the lint filter from the lint capture box, such as when cleaning the filter, it is possible to prevent foreign matter captured by the filter from falling. Furthermore, the filter strength can be improved simultaneously.

  When the lint filter 11 is set in the lint capturing box 6 after cleaning, the step portions 12a, 12b, and 12c are supported by a plurality of convex ribs 15a, 15b, and 15c provided on the bottom of the inner wall in the lint capturing box 6. In addition, by setting the height of the rib 13 at a position higher than the mesh part 12 by an H dimension, it is possible to prevent back and forth rattling and to be set stably. In case of incorrect installation such as reverse installation or oblique installation, the convex ribs 15a, 15b, 15c hit part of the lint filter 11 so that the lid 5 cannot be closed, and the filter is reversely inserted. It can also be prevented.

  Further, as shown in (a) top view and (b) cross-sectional view of the lint capture box and lint filter attached in FIG. 5, a fitting portion 26 having a substantially concave shape is formed on the side surface of the inner wall of the lint capture box 6. The end portion 14a of the partition wall 14 of the lint filter 11 is loosely fitted into the fitting portion 26 of the lint capturing box 6, and the step portion 12a at the lowest height of the step portions 12a, 12b, 12c A water gap 25 is formed by forming a gap of dimension M (dimension N from the floor surface) from the inner bottom of the box 6.

  Thereby, when setting the lint filter 11 in the lint capture box 6, the back end of the lint filter 11 is inserted into the fitting portion 26 together with the end portion 14a so as to prevent back and forth rattling and set more stably. Can do.

  Further, the same effect can be obtained with the shape of the fitting portion 27 as shown in (a) a top view and (b) a sectional view of the lint capturing box and the lint filter attached in FIG.

  Moreover, having the water inlet 7 and the water outlet 8 in the same side surface of the lint capture box 6 demonstrated by this Embodiment is only an illustration, and based on the technical idea of a claim even if it is not in the same side surface Are included in the present invention.
