[0027]
Next, the operation of the present embodiment will be described with reference to FIG.
[0028]
FIG. 4 is a cross-sectional view showing a use state of the laundry waste collecting tool 10 according to the embodiment of the present invention.
[0029]
Referring to FIG. 4, the laundry waste collecting tool 10 is kept just below the water surface W in the washing machine tub due to the buoyancy of the float 14, and the water flow A generated by the agitating blades of the washing machine (not shown). The washing water in the washing machine tub enters and exits through the opening 10 a of the laundry waste collecting tool 10. And when this washing water enters and exits, the washing waste contained in the washing water in the washing machine tub is collected in the outer net 11. In addition, when the collected laundry wastes flow back to the outside of the outer net 11, the inner net 12 exhibits a valve function, and the collected laundry wastes flow backward to the outside of the outer net 11. To prevent.
[0030]
The laundry collected below the inner net 12 further passes through the reduced diameter portion 15 of the outer net 11 and reaches the bottom 11b of the outer net 11. The laundry waste that has reached the bottom 11b of the outer net 11 is less likely to flow back upward due to the outer net 11 being squeezed by the reduced diameter portion 15, and tends to stay at the bottom 11b of the outer net 11. For this reason, the washing waste in the washing machine tub is collected one after another on the bottom 11b of the outer net 11.
[0031]
As described above, according to this embodiment, the reduced diameter portion 15 of the outer net 11 provided between the opening end 12b of the inner net 12 and the bottom 11b of the outer net 11 is collected. Is retained in the bottom portion 11 b of the outer net 11, so that laundry waste once collected by the outer net 11 can be more effectively prevented from flowing backward to the outer side of the outer net 11.
[0032]
Further, the outer net 11 is reduced in diameter by a string-like elastic member 15 a sewn on the side surface of the outer net 11 to form a reduced diameter portion 15, and the reduced diameter portion 15 extends from the elastic member 15 a. By doing so, the diameter can be expanded elastically, so that the diameter is expanded by the water flow A from the opening 10a of the laundry collecting device 10 toward the bottom 11b, and the laundry waste is easily introduced into the bottom 11b of the outer net 11. In addition, when the water flow A is weakened or the direction of the flow is changed, it is possible to prevent the diameter-reduced portion 15 from elastically contracting and washing waste from flowing out. Further, if the diameter-reduced portion 15 is enlarged with a finger or the like after collecting the laundry waste, the laundry waste staying at the bottom 11b of the outer net 11 can be easily passed through the diameter-reduced portion 15; Waste can be easily taken out of the outer net 11.
[0033]
Further, the base end portion 12a of the inner net 12 is sewn inside the vicinity of the peripheral end portion 11a of the outer net 11 so that the outer net 11 and the inner net 12 are integrated. The net support tool is not required, and the peripheral end portion 11a of the outer net 11 and the base end portion 12a of the inner net 12 are opened simply by attaching the peripheral end portion 11a of the outer net 11 to the net support tool 13. It is possible to simplify the handling of the net.
[0034]
The above-described embodiment is merely a preferred specific example of the present invention, and the present invention is not limited to the above-described embodiment.
[0035]
For example, the outer net 11 is not necessarily rectangular, and may be any shape as long as it is a bag-like shape that can effectively collect laundry waste, such as a cylindrical shape or a conical shape. .
[0036]
Further, the net support 13 does not necessarily need to be circular, and it is possible to effectively maintain the open shape of the peripheral end portion 11a of the outer net 11 and the base end portion 12a of the inner net 12 such as a quadrangular shape or a polygonal shape. Any shape such as a quadrangular shape or a polygonal shape may be used as long as it can be formed.
[0037]
Next, in this embodiment, the reduced diameter portion 15 is formed by reducing the diameter of the outer net 11 by a string-like elastic member 15a sewn on the side surface of the outer net 11, but it is not necessarily the entire circumference. There is no need to form the reduced diameter portion 15 by sewing a string-like elastic member 15a partially around the outer net 11 so that the reduced diameter portion 15 can be elastically expanded. Good.
[0038]
It is not essential that the float 14 be of a type in which two flexible circular sheets 14a and 14b made of vinyl chloride are filled with air and expanded, and a solid float made of a material having a small specific gravity is used. It may be used to generate buoyancy.
[0039]
Moreover, the float 14 is not necessarily essential, and the laundry waste collector 10 according to the present invention is a laundry waste collector of a type that is attached to the inner surface of the washing machine tub using a locking tool such as a suction cup or a clip. There may be.
[0040]
The inner ring 13a of the net support 13 does not necessarily have a rod-shaped fine projection 13c formed on the entire periphery, and the outer ring 13b is fitted to the inner ring 13a, so that the net support 13 If it is firmly locked, it is not particularly necessary.
[0041]
Further, the net support 13 itself is not necessarily connected to the inner ring 13a by the outer ring 13b having a U-shaped cross section as shown in the figure, so that the outer net 11 and the net support 13 are connected. The base end of the peripheral end 11a of the outer net 11 and the inner end of the inner net 12 is not limited to a single structure, but includes a method in which the peripheral end 11a of the outer net 11 is sandwiched between two ring-shaped members having a rectangular cross section. Various design changes are possible as long as the open shape of the portion 12a can be effectively maintained.
[0042]
Furthermore, even if there is no inner net 12 and only the bag-shaped outer net 11 is provided to collect laundry waste, the peripheral end 11a of the outer net 11 and the bottom 11b of the outer net 11 In the meantime, there is provided a reduced diameter portion 15 of the outer net 11 for retaining the collected laundry waste in the bottom portion 11 b of the outer net 11, and the reduced diameter portion 15 is sewn on the side surface of the outer net 11. If the outer net 11 is reduced in diameter by the elastic member 15a, and the elastic member 15a can be elastically expanded by stretching, the laundry once collected on the outer net 11 is used. It is possible to achieve a remarkable effect that the waste can be more effectively prevented from flowing back to the outside of the outer net 11.
[0043]
In addition, it goes without saying that various design changes are possible within the scope of the claims of the present invention.
[0044]
【The invention's effect】
As described above, according to the present invention, the reduced diameter part of the outer net causes the collected laundry waste to stay at the bottom of the outer net, so that the laundry waste once collected on the outer net is removed from the outer net. Not only can the backflow to the outside be prevented more effectively, but the open shape of the outer end of the outer net and the base end of the inner net can be achieved simply by attaching the outer end of the outer net to the net support. Since it can be maintained, it is easy to handle both the outer net and the inner net, and there is a remarkable effect that the manufacturing cost can be reduced.
