2. Description of the Related Art Conventionally, this type of washing machine for both dehydration and dehydration has been constructed as shown in FIGS. Hereinafter, the configuration will be described.

As shown in FIG. 5, a washing and dewatering tub 1 is formed by a body 2 formed of a stainless steel plate and a bottom 3 formed of a resin. A pulsator 4 is rotatably disposed on the bottom 3, and a mounting plunger 5 is mounted on the back surface of the bottom 3. The water receiving tub 6 is provided outside the washing and dewatering tub 1, and a motor 7 for driving the washing and dewatering tub 1 and the pulsator 4 is attached to the bottom surface of the water receiving tub 6. The pulsator 4 or the washing and dewatering tub 1 is driven through the ninth and ninth. The water receiving tank 6 is supported on the outer frame 10 by a suspension 11 for vibration isolation.

[0004] A fluid balancer 12 containing a liquid is fixed to the upper portion of the washing and dewatering tub 1, and a plurality of substantially cylindrical circulating water passages 13 are fitted to the inner wall surface of the washing and dewatering tub 1. The lower blade 14 is integrally provided on the back surface of the pulsator 4, and a pump chamber 15 is formed on the outer periphery of the lower blade 14.

The upper end opening 16 of the circulating water passage 13 is configured to be positioned in the fluid balancer 12, and a lint filter 17 for collecting lint from circulating water is provided at the upper end of the plurality of circulating water passages 13. I have.

As shown in FIGS. 6 and 7, the lint filter 17 has an opening 19 formed in a frame 18 and a net 20 sewn into a bag shape in the opening 19 by insert molding. The lint filter 17 is slid from above on the inner peripheral side wall surface of the fluid balancer 12 so that the opening 19 of the lint filter 17 is
It is configured to be removable so as to open toward the inside.

[0009]

However, in such a conventional structure, as shown in FIG. 7, the circulating water 25 discharged from the bottom 3 of the washing and dewatering tank 1 through the circulating water passage 13 is used as a lint filter. Since the water is discharged so as to be perpendicular to the net 20 insert-molded in the frame 18 of 17, the water in the washing and dewatering tub 1 can be filtered by the net 20, and the lint in the washing liquid can be collected. Was possible.

However, the circulating water 25 discharged in this manner is
Is constantly discharged so as to be orthogonal to the net 20 of the lint filter 17 at the location where the water pressure is highest near the opening 19, so that the surface where the circulating water 25 is orthogonal is entangled with fine lint 26 in the mesh of the net 20. It adhered in a state of being clogged.

The lint that has flowed into the lower end of the net 20 accumulates circulating water at the end of the net 20 and the net 20 is in a swelling state. And no clogging occurs.

As described above, since the thread waste 26 clogged in the vicinity of the opening 19 is entangled with the stitch of the net 20,
In some cases, the net 20 was not easily removed by hand, was left as it was, or was forcibly rubbed against the net 20 so that the net 20 was damaged. In addition, since dirt and detergent are attached to the remaining thread waste, mold and the like may be easily generated.

As a countermeasure, in order to improve the durability of the net 20, the material of the net 20 is made of a highly durable one, or the net 20 is made detachable and replaceable, but the durability is limited. In addition, when clogged, there is a problem that the number of times of replacement is increased because it is easily damaged.

The present invention has been made to solve the above-mentioned conventional problems, and prevents circulating water discharged from a circulating water channel from being discharged orthogonally to a net of a lint filter to prevent fine lint from being clogged in the net. It is intended to prevent the damage of the net due to clogging and to improve the lint collecting performance.

Attach a lint filter to the opening. The lint filter is provided with a rectifying means for rectifying circulating water such that a net formed in a bag shape is attached to a frame and the circulating water discharged from the net does not go straight.

[0016] Thus, by preventing the circulating water discharged from the circulating water passage from being discharged orthogonally to the net of the lint filter, the net can be prevented from being clogged with fine lint, and the net due to clogging can be prevented. Can be eliminated and the lint collecting performance can be improved.

Embodiments of the present invention will be described below with reference to the drawings. The same components as those in the conventional example are denoted by the same reference numerals, and description thereof is omitted.

(Embodiment 1) As shown in FIGS. 1 to 3,
In the lint filter 27, an opening 29 is formed in a frame 28, and a net 30 sewn in a bag shape is mounted on the opening 29 by insert molding. Lint filter 1
Numeral 7 is configured to be slidably mounted on the inner peripheral side wall surface of the fluid balancer 12 from above so that the opening 29 of the lint filter 27 can be attached and detached so as to open into the washing / dewatering tub 1.

The guide frame (rectifying means) 31 rectifies the circulating water so that the discharged circulating water does not go directly to the net 30. The guide frame (rectifying means) 31 is formed in the opening 29 of the frame 28 of the lint filter 27 from above the opening 29. It is formed integrally with the frame 28 so as to cover in a U-shape. The inclination angle θ of the guide frame 31 is smaller than the opening 29 by the opening 32.
Is set not to be small. The guide frame 31 is formed so as to be connected to the upper end opening 16 of the circulation channel 13.

When the pulsator 4 rotates, the circulating water is discharged from the circulating water passage 13 through the upper end opening 16 of the fluid balancer 12 toward the center of the washing and dewatering tub 1. At this time, the circulating water is discharged toward the guide frame 31 formed in the opening 29 of the lint filter 27, rectified by the guide frame 31, and discharged downward of the washing and dewatering tub 1. Therefore, the net 30 opened in the lower opening 32
Can be discharged.

Accordingly, by providing the guide frame 31 so as to cover in a substantially U-shape and controlling the discharge of the circulating water so as not to be orthogonal to the net 30, the circulating water is always discharged so as not to be orthogonal to the net 30. Therefore, the water flows out so as to wash the surface of the net 30 and does not cross the mesh. For this reason, it is possible to prevent fine thread waste from clogging the mesh of the net 30. Since this clogging does not occur, damage to the net does not occur.

(Embodiment 2) As shown in FIG. 4, a lint filter 33 has an opening 35 formed in a frame 34,

The operation of the above configuration will be described. By supporting the guide frame 37 rotatably by the water pressure of the circulating water, the area of the lower opening 39 can be changed by the water pressure of the circulating water. That is, when the pressure of the circulating water is low and the discharge flow rate is low, the guide frame 37
In the state shown by the solid line in FIG. 4, the circulating water is prevented from being orthogonal to the net 36. When the water pressure of the circulating water is high and the discharge flow rate is large, the guide frame 37 is in the state shown by the two-dot chain line in FIG. Thus, the circulating water can be prevented from being orthogonal to the net 36.

Therefore, even when the discharge flow rate is large, the guide frame 37 does not become a resistance and does not discharge in the lateral direction of the net 36, thereby preventing the net 36 from being clogged with lint. Can be.
