DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lint filter for a washing machine, which is formed into a bag by a net.

[0002]

2. Description of the Related Art Conventionally, such a lint filter for a washing machine has been formed in a bag shape with a net. Specifically, a marquisette-knitted net has an outer surface knitted like an ordinary cloth product. It is formed into a bag shape with the back knitting surface inside and the sewn portion inside, and the washing machine is arranged so that washing water is passed through the mouth of the washing machine. It is designed to capture lint contained in water.

[0003]

However, in the case of the prior art described above, the lint adheres extensively and robustly to the net of the lint filter, easily causing clogging, and losing water permeability early. There was a problem that the lint capture performance was poor. In addition, there is also a problem that the clogged lint filter swells with water, so that the water flow in the tank hits the water and causes water splash. Further, the lint easily adheres to the sewn portion of the lint filter, and the addition of dirt to the lint filter causes a problem that the sewn portion becomes dirty as the blackened portion eventually becomes dark.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is therefore an object of the present invention to provide a washing machine which is less likely to cause clogging due to the adhesion of lint, has excellent lint capturing performance, and does not cause water splashing. provide lint filter machine, in addition, the lint adhered difficult to suture portion, to provide a cleanly lint filter for a washing machine that can also continue to use.

[0005]

In order to achieve the above object, a lint filter for a washing machine according to the present invention is characterized in that it is formed in a bag shape with the surface of the marquisette knitted inside.

[0006]

[0007] Also, while the Omoteami surface of marquisette knit inward, the suture portion is outwardly that is formed in a bag shape
Also features .

[0008]

[Function] The surface knitting and the knitting of the back knitting surface of the marquisette knitting are different from each other. On the surface knitting, the warp and weft are knitted only by the warp and weft. In addition, the diagonal thread is knitted. Although this is to prevent the mesh from shifting, the diagonal yarn is apt to be linted, and the lint that has been hung further penetrates between the diagonal yarn and another yarn. On the other hand, there is no diagonal thread on the front knitting surface, and because of the simplicity of only the warp and weft, the lint is just about to be placed on the weft, so it immediately separates from it and goes inside the bag and is collected at the bottom. become. For this reason, the mesh of the lint filter is left without clogging, and good water permeability is ensured. Therefore, according to the lint filter of the present invention formed in a bag shape with the outer knitted surface having no diagonal yarn of marquisette knitted inside, clogging due to adhesion of lint is less likely to occur, and good water permeability can be secured.

If the sewn portion is also inside the lint filter, lint and dirt tend to adhere and remain, but if it is outside the lint filter, it does not easily adhere and remains. Therefore, Makize
According to the lint filter of the present invention, which is formed in a bag shape with the outer knitted surface having no diagonal thread of the knitting on the inside and the stitched portion on the outside, clogging due to adhesion of lint is caused.
It is possible to obtain a material that does not cause lint or dirt remaining on the sewn portion.

[0011]

An embodiment of the present invention will be described below with reference to the drawings. First, FIG. 2 shows the configuration of the entire washing machine, in which an outer tub 2 for storing water is provided in an outer box 1 with a plurality of hanging rods 3.
The inner tub 6 having a large number of dehydration holes 5 on the peripheral side is disposed inside the outer tub 2 by elastic support by a suspension mechanism 4 mainly composed of
Further, a stirring member 7 is disposed at the bottom in the inner tank 6.

A drive mechanism 9 mainly composed of a motor 8 is disposed below and below the outer tub 2. The drive mechanism 9 stops the inner tub 6 during washing and rotates the agitator 7. Let
The inner tub 6 is rotated together with the stirring body 7 during dehydration. In addition, a drain valve 10 and a drain hose 11 for draining water from the inside of the outer tank 2 (the inside of the inner tank 6) are provided in a lower part of the outer tank 2 outside.

[0013] A pumping passage 14 is formed on the peripheral side of the inner tub 6 by a concave portion 12 extending vertically and a cover 13 closing an open portion facing the inner tub 6. A pump blade 15 formed on the back surface of the agitator 7 faces the pumping path 14 at the lower end, and a lint filter 16 is mounted at the upper end.

The lint filter 16 is formed in a bag shape as shown in FIG. 3 by a net 17 knitted with a marquisette, and in detail, only the warp yarn 18 and the weft yarn 19 shown in FIGS. Front knitting surface (Fig. 4)
) On the inside, and the warp yarn 18 and the weft yarn 19 further include the diagonal yarn 2.
The back knitted surface (see FIG. 5) on which the "0" is entangled is turned outward, the edges are sewn over, and the sewn portion 21 is turned outward to form a bag-like shape. Frame 2
2 is attached to the upper end of the pumping channel 14 by the mounting frame 22 and communicates with the pumping channel 14.

Now, in the case of the above-described configuration,
As described above, when the washing operation is started, the inner tub 6 is stopped and the stirrer 7 is rotated, but the rotation of the stirrer 7 causes the pump blade 15 to move the washing water in the inner bottom of the inner tub 6. Is sucked and sent into the water pumping path 14, and the water is pumped up from the water pumping path 14 and circulated through the lint filter 16 from the mouth of the lint filter 16 and returned to the inner tub 6. The lint scattered from the washing water and contained in the washing water is captured by the lint filter 16 while the washing water passes through the above-described lint filter 16.

By the way, the lint filter 16 is formed of the net 17 knitted by Marquisette, because unlike the woven fabric, the thread is not frayed at the sewn portion 21 at the edge.
However, the net 17 knitted by this marquisette has a different way of entanglement of the yarn between the front knitting surface and the back knitting surface. On the other hand, the warp yarn 18 and the weft 1
Further, a diagonal thread 20 is knitted around 9. This is to prevent the mesh from shifting. When the surface stitches are rubbed against each other, the warp yarns 18 are easy to slide in the direction in which the warp yarns 18 are arranged (the horizontal direction in FIG. 4), but the direction in which the weft yarns 19 are arranged (see FIG. 4). On the other hand, when the back knitting surfaces are rubbed against each other, the warp yarns 18 are aligned (the horizontal direction in FIG. 5) and the weft yarns 19 are aligned (the vertical direction in FIG. 5).
Easy to slip to any of the.

For this reason, conventionally, it has been considered that when the lint filter is formed in a bag shape with the back knit surface inside, the lint does not need to be caught. However, in a conventional lint filter formed in a bag shape with the back knitted surface inside, the lint is applied to the diagonal thread 20 existing on the back knitted surface as shown in FIG.
Lint A is easily hooked like a lint A shown by a two-dot chain line, and the hung lint A further bites between the diagonal yarn 20 and the other warp yarns 18 and weft yarns 19. For this reason, lint A adheres strongly to the mesh of the lint filter, and cannot be removed even if it is removed by hand. Lost. Therefore, the lint trapping performance deteriorates early, and the clogged lint filter swells with water, so that the water flow in the inner tank 6 hits the water and causes water splash.

On the other hand, since the surface knitting surface does not have the diagonal yarn 20, but has only the warp yarn 18 and the weft yarn 19, the lint is like the lint A shown by the two-dot chain line in FIG. As soon as it gets on 19, you can quickly get away from it and go inside the bag and collect at the bottom. For this reason, the mesh of the lint filter is left without clogging, and good water permeability is ensured. Therefore, according to the lint filter 16 of the present invention formed in a bag shape with the front knitted surface inside, it is difficult to cause clogging due to the adhesion of lint, good water permeability can be secured, and the lint capturing performance can be improved for a long time. It can be maintained well, and the lint filter 1
The inner tank 6 does not swell with water.
The water flow inside can be prevented from hitting it and causing water splashing.

FIG. 1 shows this as an experimental result. In this case, the lint filter 1 of the present invention shown in FIG.
6 and the conventional lint filter shown in (b), first put an appropriate amount of lint, and then continuously apply bleached cloth for 10 times.
The lint was captured for 3 minutes in a washing tub full of lint by washing for 0 hours, and the lint was removed from the eyes of the lint filter 16 by ordinary washing to see how the lint was removed. In the case of the lint filter, a large amount of lint remains on the eyes, whereas in the lint filter 16 of the present invention, the lint separates from the eyes and accumulates at the bottom, and most of the mesh remains without clogging. I understand.

If the sewn portion 21 is also inside the lint filter 16, lint and dirt are likely to adhere and remain.
If it is on the outside, it will not adhere easily and will not remain. Therefore,
Turn the front side of the marquisette knitted thread 20
Rutotomoni, said suture portion 21 to the lint filter 16 is outwardly present invention formed in a bag shape, the lint adhered
Hard to cause clogging and lint of the suture portion 21
A product that does not cause any remaining residue of dirt is obtained.
