Abstract

PROBLEM TO BE SOLVED: To eliminate the cause of entanglement of waste accumulated in a lint filter of a washing machine with the lint filter, thereby facilitating the removal of fiber waste and foreign matter.SOLUTION: A woven fabric having a fine texture is employed as a woven fabric of a lint filter of a washing machine. Thereby, fiber waste or the like is collected in a state without getting into the texture, so that the fiber waste or the like can be easily removed without causing clogging. In addition, drainability is so excellent that the fiber waste or the like accumulated in the lint filter does not cause contamination, and time and labor for removal can be saved. Furthermore, the fiber waste and foreign matter can be easily removed by arranging a seam on the outside.

Description

  The present invention relates to a washing machine waste thread filter.

Conventionally, when washing is performed with a vertical washing machine / washing / drying machine and a two-tank washing machine, fiber waste, soap residue, sand, mud, and the like are stored in a waste thread filter that is standard equipment in the washing machine.
In order to remove the accumulated fiber waste, soap residue, sand, mud, etc., it is turned upside down, but the fiber waste is entangled in the filter texture and seam, which takes time and effort.
As one of the solutions, disposable washing machine lint filter fittings made of rubber integrated with a non-woven fabric in the shape of a triangular bag have been developed. It's not a gentle way. (For example, see Patent Document 1)

JP2008-229304

  As described in the prior art, in order to remove fiber waste, soap residue, sand, mud, etc. accumulated in the bag-like lint filter provided as standard in the washing machine, turn it over and wash it in water. Or, the filter is rubbed and removed with a toothbrush, etc., but fiber scraps are entangled in the texture and seam of the filter, and it takes time and effort to remove it cleanly.

  Accordingly, the present invention addresses the problem that fiber waste, soap residue, sand, mud, etc., collected on a waste thread filter of a washing machine are difficult to adhere, and can easily remove fiber waste, etc. accumulated in the waste thread filter. It intends to provide a waste filter.

  The present invention according to claim 1 is a washing machine using a fabric in which the number of spun yarns of synthetic fibers is 60 to 140 yarns / inch of warp yarns per inch or warp yarns. Get a lint filter.

  According to a second aspect of the present invention, there is provided the washing machine waste thread filter according to the first aspect in which the shape of the waste thread filter is any one of a bag shape and a collection sheet shape.

  In the present invention, by adopting a fine weave, fiber scraps are not caught and clogged, so that they are collected in a floating state from the filter and can be easily removed. In addition, since the drainage is good, there is no dirt due to the fiber waste accumulated in the lint filter, and it can maintain a clean feeling forever.

  As for the seam of the bag, the fiber is not easily entangled when the seam is on the outer side, and the accumulated matter in the filter can be easily removed. Further, when the bottom portion of the lint filter bag is folded, fiber waste, soap residue, sand and mud adhering to the seam are reduced and can be removed more easily.

It is a perspective view which shows one Embodiment of the bag-shaped waste thread filter of this invention. It is a top view of the outer frame and lattice of the collection sheet-like waste thread filter of this invention. It is a top view which shows one Embodiment of the collection sheet-like waste thread filter of this invention.

According to the first aspect of the present invention, a waste thread filter for a washing machine is obtained by using a woven fabric in which warp yarns or weft yarns of 60 to 140 yarns / inch are driven per inch.
By using synthetic fibers made of nylon, polyester, polypropylene, and acrylic fibers, it is difficult for cotton and rayon fibers, which are hydrophilic fibers, to adhere to hydrophobic synthetic fibers that have opposite properties. Therefore, it becomes easy to remove lint and dust attached thereto.

The conventional vertical washing machine / washing / drying machine and the two-tank washing machine are more easily damaged than the drum-type washing / drying machine, and are liable to generate waste fibers when washed. Although there are some differences in the texture of the lint filter provided as standard in commercially available washing machines, generally 25 to 60 threads / inch are used (for example, NW-D7LXE7 manufactured by Hitachi). 2 are standard equipment of 25 × 60 / inch).
On the other hand, the present invention makes it easier to remove fiber waste, soap residue, sand and mud remaining in the filter by making the texture finer than the standard waste thread filter. Devised.
If the number of driving is coarser than 60 / inch, fine fiber scraps flow out or get caught in the weave and cause clogging, which makes it difficult to remove the fiber scraps. Also, if it is finer than 140 bottles / inch, the passage of the washing water will be poor, and if it becomes clogged, the washing water will not pass through the filter and will not function as a filter.

  The present invention according to claim 2 provides the washing machine waste thread filter according to claim 1, wherein the waste thread filter has a bag shape or a collecting sheet shape.

  As shown in FIG. 1, the bag-shaped lint filter is obtained by welding or bonding the fabric (2) to a plastic frame (1) to obtain a lint filter.

  When obtaining a bag-like filter, the bag can be sewn either by bag sewing or lock sewing, and the bag can be sewn either on the two sides of the bag, on the bottom 3 or on the side 2 However, in order to avoid catching on the sewn part, it is better to bend the bottom part without sewing.

  In the case of a bag-like lint filter, by making the seam outside, fiber waste, soap residue, sand and mud can be made difficult to adhere to the seam portion.

  As shown in FIG. 2, the collection sheet-like lint filter is obtained by welding or adhering the woven fabric to an integrally molded product in which a lattice (3) is attached to a plastic frame (4).

One washing machine is equipped with two lint filters, one is fitted with the bag-like lint filter obtained in the present invention, and the other is standard with a washing machine. As a comparative example, it was used for 2 months. In these examples, the ease of cleaning after use of fiber waste, soap residue, sand, mud, etc. collected in the filter was compared.
The washing machine used was a Hitachi vertical washer-dryer (NW-D7LXE7 type).
EXAMPLES Hereinafter, although an Example demonstrates this invention further in detail, this invention is not limited to these Examples.

FIG. 1 is a perspective view of a waste thread filter main body.
As a waste thread filter, Toray Skylark C-119 (polyester shear, the number of driven yarns was 100 warps / inch, wefts 89 / inch, and used yarn was 30 denier).
When the lint filter after 2 months of use was observed with a microscope, it was collected in a floating state, with no waste fibers inside the fabric weaves or seams. We were able to.

Comparative example

The standard waste thread filter was 25 × 60 / inch.
The lint filter after 2 months of use is severely soiled by lint etc. accumulated in the lint filter and does not feel clean. It took time and effort to remove it cleanly.
When the waste thread filter after use was confirmed with a microscope, fiber wastes entered into the fabric weaves and seams, causing clogging. This is considered to have occurred due to the coarse texture. It was also confirmed that draining was bad.

The denier indication of the spun yarn and the cotton count are as follows: Denier is 9000 meters, 1 g is 1 denier, 2 g is 2 denier, and cotton count is 768.1 m (840 yards) long. The first weight is 6g (1 pound), and the second weight is the weight of a 768.1m × 2 yarn of 1 pound.
From this relationship, if the denier is D and the count is S, the following equation holds.
D (denier) = 534.9 / S (counter)
In addition, the relationship between the diameter of the yarn indicated on the denier and the denier is as follows.
Assuming that the specific gravity is d and the weight is w (grams), the following equation is established from the relationship of specific gravity = weight (grams) / volume (cubic centimeter).
φ (cm) = SQR (D / d) × 0.0011832
The following table is derived from this relationship.

table. Spinning yarn diameter (mm)

Considering the width and length of the weave when the diameter and weft are the same, using the table (0020), the weave 1 when 25 spun yarns are driven between 1 inch (25.4 mm) One length is 1.016 mm (25.4 / 25) −0.055 mm (diameter of 30 denier polyester spun yarn) = 0.96 mm. Similarly, when driving 60 pieces of the present invention, it is 0.368 mm. As a result, when the spun yarn used for the woven fabric of the present invention is a normal yarn count (40 to 80 yarn), the thickness of the spun yarn is larger than that of the yarn yarn 60 of Example 1, and the texture becomes smaller. . In the present invention, since the yarn is made smaller during the washing process and the lint is less likely to enter the weave, the thickness of the spun yarn used for the fabric is not specified because it can be used within the range of the spun yarn used normally. did.

The number of spun yarns used for shirting and sweaters is 40 to 60. For this reason, most of the yarns that fall off these counts are also lint caught on the filter during washing. According to the calculation of (0020), 25 with a small number of driven yarns have an interval of 0.96 mm in the width of the weave, and the end of the 40th cotton yarn having a diameter of 0.11 mm is in this weave. The possibility of entering is high. On the other hand, when the number of driven-in yarns is 60 according to the present invention, the texture becomes 0.368 mm, and the possibility that the end of the cotton yarn enters the texture becomes small. From this trial calculation, by setting the number of drivings to 60 or more, there is little possibility that the bridge of the waste thread enters the texture of the filter, and as a result, the waste thread on the filter can be easily removed.
