JPS6036233Y2 - Washing machine lint capture device - Google Patents

Description

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

In the figure, reference numeral 1 denotes a washing tank, which has an approximately rectangular planar surface with its upper surface open, and has an inner bottom surface 1b that slopes upward toward the corner 1a. It is provided with a stepped portion 1c formed to protrude.

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 1d formed in the recessed portion 1d, 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 that fits into the opening formed by the cover 10 and the groove 9, and a projecting piece 1 protruding from the back surface of the upper end.
1b is fixed to the stepped portion 1c with screws 13.

The upper end of the pipe 11 protrudes above the stepped portion 1c, and the upper end opening, that is, the spout 12a of the spout 12, opens toward the inside of the washing tank.

Reference numeral 14 denotes a filter for capturing thread waste, which is shaped like a bag and has a frame member 14a at its opening.

Reference numeral 15 denotes a filter holder for attaching the filter 14, which is located on the ceiling wall 15a having a planar shape that matches the corner of the washing tank above the step 1c, and on the left and right sides of the spout 12a, and for washing the step IC. A pair of side walls 15b that cover the inside of the tank
, 15b are integrally molded.

A pair of grooves 15c, 15C extending in the vertical direction are provided on opposing end surfaces of the left and right side walls 15b, 15b, and the upper ends and opposing surfaces of both grooves are open.

The filter receiver 15 has its ceiling wall 15a fixed to a small step 1e provided further above the step 1c with screws 16, and the filter receiver 15 is inserted into a notch 15d provided on the upper surface of the ceiling wall 15a closer to the inside of the washing tank. A projection 17 protruding from the inner surface of the tank is brought into contact with the filter receiver from above to prevent the end of the cleaning tool 15 closer to the inside of the tank from lifting up.

The filter 14 has its frame member 14a attached to the filter receiver 15.
115c, 15c 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 from the through hole 6a of the suction channel 8 by the pumping action of the vanes 2a, and is sent to the water spout 12 by centrifugal force, and is filtered from the water spout 12a. 14 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 14 is removed from the frame member 14a by the groove 15.
It can be removed by pulling it upward from c and turning the filter 14 over.

5 to 7 show other embodiments of this invention, in which the same parts as in the previous embodiment are given the same reference numerals.

In this embodiment, the filter holder 15 is a ceiling wall 15a.
It has a wall 15e that hangs down so as to cover both left and right sides and the back surface of the pipe 11, and a protrusion 15f provided at the lower end of the wall 15e is fitted into a recessed hole 1f of the stepped portion 1e.

The pipe 11 has protrusions 11c provided on both left and right sides of the upper end of the pipe 11.
The filter receiver is fixed by pressing the protrusion 11c at the lower end of the left and right sides of the lower wall 15e.

In addition, the filter receiver 15 has a projection piece 15g protruding from the side of the ceiling wall 15a fixed to the flange 1g between the washing tank and the dehydration tank with a screw 18, and covers the upper surface of the dehydration tank and the clothes input port 19a. It is covered by a cover 19 having a.

As described above, this invention is based on a filter holder that is manufactured by integrating a ceiling wall with a planar shape that matches the corner of the washing tank where the spout opens, and a pair of side walls located on the left and right sides of the spout opening. Since the filter is fixed to the corner of the washing tank, the filter can be installed facing the opening of the spout in a good manner, and the appearance of this part can be improved. There is no detergent solution flowing in between the pipe and the corner of the washing tank, and dirt does not accumulate due to dirt buildup, and even if dirt gets on the ceiling wall soil of the tool, the filter holder can be easily removed. can.
