Then, the screw 37 screwed into the screw hole 28 from the screw insertion hole 34 is tightened, and the filter table 24 is attached to the inner basket 7.

As a result, the washing agent inlet 25 of the filter base 24 is connected to the inner basket 7 on which the filter base 24 is mounted.
The inner surface of the inner basket 7, the bottom cover 8, and the gap 10 between the agitator 9 and the inner peripheral surface of the inner tub 4 are the laundry processing agent passages 27. The washing agent passage 27 connects the washing agent inlet 25 and the washing agent outlet 33.

The filter base 24 is fitted with shafts 40 protruding from the upper and lower central portions of the opening frame 39 of the lint filter 38 in the bearing holes 32, whereby the lint filter 38
Is mounted so that the lint can be efficiently captured by swinging according to the washing water flow.

Now, in the case of the configuration as described above,
When a washing agent (liquid) such as a detergent or a bleach is injected from the washing agent inlet 25, the washing agent flows into the washing agent passage 27.
