(49) is a ring filter that is removably fitted into the front side of the recess <41) of the balance ring <34>, and is located directly below the discharge port (48) to receive the discharged water. is dropped into the tank from directly above. This lint filter (4
9) is a round-shaped ne/! as shown in Figure 6.・It consists of a synthetic resin filter frame (51) to which a filter 50) and this net (50) are attached, and both sides of the filter frame (51) are formed into a square frame shape, and the outer side is thicker than the frame body. is an elastic piece (52) that is thin and has elasticity;
2) is provided with an engaging portion (53) consisting of a protrusion.

On the other hand, opposite both walls (
54) is provided with an engagement receiving part (55) consisting of a groove that elastically engages with the above-mentioned engagement part (53), and the quilter frame (51)
) into the recess (41) and remove the fin reflex frame (51).
The filter (49) is attached by fitting the square frames on both sides of the filter (49) into the both side walls (54) and allowing the engaging portion (53) and the engaging receiving portion (55) to engage with each other. Also, above
) Both side walls (54) are integrally formed with pedestals (56) for holding the filter frame (51) so that it does not fall.

When the filter (49) is installed in the recess (41), the hand-off side of the filter frame (51) protrudes from the recess (41) as shown in Figure 4, so hold this part. The filter (49) can be easily removed from the recess (41) by pulling it toward you. Also,
The pedestal (56) also protrudes from the recess (41),
This serves as a guide when inserting the filter frame (51) into the recess (41).

(57) is a lip formed so as to hang down by the dimension <A) on the outer periphery of the rotation R (7), which increases the pressure in the pump chamber (21) during rotation, and pumps the tank through the gap of the opening (6). Reduces the amount of water that comes out. <58) is the above outer tank <1
) is an annular outer tank cover placed over the top of the tank.

When explaining the operation, first of all, when washing or rinsing, the rotary blade (7
) rotates, water between the outer tank (1) and the dehydration tank (2) flows through the pump chamber (21) through the through hole (22) as shown by the arrow in Figure 1, due to the pumping action of the back blades (9). ).

Most of the sucked water is quickly sent out along the straight portions (24) (24) to the open portion (23) no matter which direction the rotor (7) rotates, and from there to the discharge path ( 28>, through the discharge pipe (33) and the passage (47), and from the downward discharge port (48>) to the phosphorus filter (49).
It is discharged approximately vertically into the dehydration tank (2) through the .

In this way, less water circulates in the pump chamber (21), so less water comes out from the opening (6) into the dehydration tank (2), and most of the water is inside the dehydration tank (2). Since the rotating water flow overlaps perpendicularly to the rotating water flow, the water flow becomes complicated, and it is possible to promote the vertical rotation of the laundry, improve the washing efficiency, and suppress uneven washing. In particular, since the discharged water does not spread and falls directly below, it hits the laundry that is trying to float and sinks it under the water surface, further improving the washing efficiency.

Use a lint filter (49) to remove lint, etc. contained in the water.
will be reliably collected. At this time, the discharge [-1 (48
) flows down toward the tip of the net (50), so thread waste accumulates from the tip of the net (50).
Lint waste can be easily removed from the net (50) when cleaning the filter (49). Temporary net (50)
Even if there is some lint that could not be caught at the tip of the thread, as shown in Figure 1, wash the tip of the thread 1-(50) at the water surface < L.
＞、、If the size (B) is lower than (at high water level), the washing water flow and laundry will hit the net (50), and the vibrations at this time will remove the lint caught by the net (50) at its tip. can be pushed to To clean the filter (49), remove the filter frame (51) from the recess (41) and turn over the net 1-(50). Therefore, all you have to do is insert it into the recess (41) without worrying about the direction, making it easy to use. Moreover, the net (50) can be used even if it is turned upside down.

By the way, during dehydration, the lint filter (49) is subjected to centrifugal force (J), so that the filter frame (51) tends to become even more flat, that is, the lateral dimension of the filter frame (51) expands, and the engaging portion (53) Since it more reliably engages with the retaining receiving part (55), there is no fear that it will come off due to centrifugal force.

In addition, a through hole (59) is provided in the filter frame (51) as shown in Fig. 7.
), even if the net (50) becomes clogged with thread waste, the water coming out of the discharge port (48) will flow through this hole (
59) into the dehydration tank (2), and the Noilku frame (5
1) There is no unsightly overflowing from above, thereby preventing thread waste from adhering to the fitting portion between the engagement receiving portion (55) and the engagement portion (53).

It is also possible that the laundry gets entangled with the filter (49) during washing or rinsing, and is removed by pulling it in the circumferential direction.
Since the portions of the filter frame (51) connected to the elastic pieces (52) on both sides are thick, the rigidity in the circumferential direction is large. That is, the filter (49) allows the elastic force of the elastic piece (52) to act in the direction of the inside and outside of the tank, but does not allow the elastic force to act in the circumferential direction. It doesn't come off easily.

In addition, when cleaning the discharge waterway in case of clogging, etc., remove the cover (44) to expose the passageway (47) and clean the discharge pipe (
33> can also be taken out for easy cleaning.

(G) Effects of the Invention According to the present invention, in addition to operating the lint filter from the internal force of the tank, the filter frame can be used as a knob, which greatly improves the ease of attaching and detaching the lint filter. can be improved. Therefore, it is possible to provide a dehydrating washing machine that is extremely easy to use.
