Description

[Detailed Description of the Invention] This invention relates to a washing machine, and particularly to a device for catching lint that comes loose from clothes during washing operation.

In the figure, reference numeral 1 denotes a washing tank, which has a substantially rectangular plane with an open upper surface and an inner bottom surface 1b that slopes upward toward a corner 1a.

2 is a pulsator for washing rawhide with an inclined inner bottom surface 1b.
It is rotatably attached by a shaft 3 to a concave portion 1c formed in the recess 1c, and has blades 2a extending in the radial direction on the back surface.

Reference numeral 4 denotes a groove formed from the bottom of the concave portion 1c toward the downward slope of the inner bottom surface 1b, and has a drain port 5 at its lowest point.

The upper surface of the groove 4 is covered by a cover 6, while an open lower portion is left on the lower surface near the center of the pulsator 2.

The cover 6 has a large number of through holes 6a at positions that do not overlap under the pulsator 2, and connects to the groove 4 at a position lower than the water level in the washing tank.

As a result, the groove 4 cooperates with the cover 6 to form a suction channel 8 that sucks water in the washing tank from the through hole 6a through the open lower part by the pumping action of the blade 2a as the pulsator 2 rotates.

9 climbs up the inner bottom surface 1b from the outer periphery of the concave portion 1c to reach the corner 1a.
The upper surface of the groove on the inner bottom surface 1b is covered with a cover 10, and a flat pipe 11 is fitted and fixed in the groove on the corner 1a to form a discharge channel 12.

The pipe 11 has a small diameter stepped portion 11a at the lower end fitted into the opening formed by the cover 10 and the groove 9, and a protrusion 11b (Fig. 3) projecting on both left and right sides of the upper end fitted into the notch 9a on both sides of the groove 9. A filter receiver, which will be described later, is fixed by pressing the upper surface of the protrusion 11b on the lower surface of the side wall of the box-shaped portion of the tool 14.

The washing tank 1 has a step 1d formed above the corner 1a so as to project outward from the same kind, and the pipe 11 is made to protrude above the step 1d.

The upper end opening of the pipe 11, that is, the spout 12 of the spout 12
A opens toward the inside of the washing tank.

Reference numeral 13 denotes a filter for catching thread waste, which is shaped like a bag and has a frame member 13a at its opening.

Reference numeral 14 denotes a filter holder for attaching the filter 13, and a plate-shaped wall 14a placed on the stepped portion 1d of the washing tank.
A box-shaped portion 14b that covers the top and side surfaces of the pipe 11, and a pair of side walls 14c, 14c located on both left and right sides of the spout 12a and covering the stepped portion 1d against internal forces of the washing tank are integrally molded on both sides. A pair of grooves 1 extending vertically on opposite end surfaces of the wall
4d and 14d.

The filter receiver 14 is a screw 15 inserted into the plate-like wall 14a.
is fixed on the stepped portion 1d.

The filter receiver 16 is a cover that covers the upper surface of the tool 14, and has a planar shape that matches the upper corner of the step portion 1d and does not cover the upper end of the groove 14d.

The cover 16 has a rib 16a and an elastic claw 16b on the lower surface, and is fixed by bringing the rib 16a into contact with the ceiling wall of the box-shaped portion 14b and fitting the elastic claw 16b into a through hole 14e provided in the ceiling wall. Ru.

The filter 13 connects its frame member 13a to the filter receiver 14.
When inserted into the grooves 14d, 14d from above, the opening faces the water spout 12a.

When the pulsator 2 is rotated to start the washing operation, the water in the washing tank is sucked through the through hole 6a of the suction channel 8 by the pump action of the blades 2a, sent to the spout 12 by centrifugal force, and filtered from the water spout 12a. 13 and returns to the washing tank 1.

This allows lint to be captured from the circulating water stream.

The thread waste accumulated in the filter 13 is removed from the frame member 13a by the groove 14.
It can be removed by pulling it upward from d and turning the filter 13 over.

As described above, this invention allows the filter to be attached and detached by simply inserting and pulling out the filter frame member into the groove of the filter receiver, making it easy to remove lint from the filter and attach the filter. It is something that can be done.

In addition, the filter receiver has a pair of side walls on the left and right sides of the ingredients, and the filter receiver covers the top surface of the ingredients, so the appearance of the corner of the washing tank is improved. There is no accumulation of dirt or dust on the cover, and even if dirt does get on the cover, it can be easily removed.

Furthermore, since the filter holder is installed by hooking the cover onto the tool with nails, screws, etc. are not exposed on the cover, creating a beautiful appearance, and there is no need to provide a hole for attaching the cover to the washing tank, which prevents water leakage. This has the effect of being able to eliminate the problem.
