Description

  The present invention relates to a dehydrating and washing machine in which a filter mechanism is provided inside a washing and dehydrating tub.

  Conventionally, in this type of dehydrating and washing machine, a filter mechanism is provided on the wall of the washing and dehydrating tub stored in the water receiving tank, and the lint in the washing water is removed by the filter section that rotates according to the water flow of the filter mechanism. It was made to collect (for example, refer patent document 1).

  5 and 6 show an exploded perspective view and a cross-sectional view of a main part of a filter mechanism of a conventional dehydrating and washing machine described in Patent Document 1. FIG.

  5 and 6, the washing and dewatering tub 1 is configured such that the side wall 2 has a double structure in which an inner wall 3 made of a stainless steel plate is provided on the inner surface side through a predetermined gap. The inner wall 3 is formed with a concave portion 3a having a substantially square opening in the middle portion of the inner surface, and the filter mechanism 4 is attached to the concave portion 3a at a position where washing water flows when washing or rinsing.

  Two mounting holes 3b and 3c are formed in the upper bottom portion and the lower side portion of the recess 3a, respectively, and the filter mechanism 4 can be smoothly removed from the upper and lower side portions. Recesses 3d and 3e are formed so that they can be performed.

  The filter mechanism 4 has a substantially square cover shape and is attached so as to cover the concave portion 3a from the inner side of the tank, and rotates in the filter attachment member 5 as indicated by a thick arrow X0 in FIG. It has the filter part 6 attached freely. The filter unit 6 has a structure in which a bag-like filter 8 is attached to a filter case 7 having a substantially square frame shape.

  The filter mounting member 5 has a central opening 5a at the center, and upper and lower end plates 5b and 5c have shaft holes 5d. Further, the filter mounting member 5 has an inflow restricting side wall 5e having a predetermined height as an inflow restricting portion between the edge contacting the bottom surface of the concave portion 3a of the inner side wall 3 of the side portion and the central opening 5a. It is formed to resist the flow of the washing water inside, and a plurality of flow openings 5f are formed in the inflow restricting side wall 5e so as to have a predetermined interval.

  Then, by inserting shaft portions 7a and 7b extending outward from the upper and lower end portions of the filter case 7 into shaft holes 5d formed in the upper and lower end plates 5b and 5c of the filter mounting member 5, the filter portion 6 is It is detachably attached to the filter attachment member 5 and is rotatably attached.
