Description

  The present invention relates to a lint collecting tool that can prevent backflow of captured lint and a washing machine equipped with the lint collecting tool.

  Patent Document 1 discloses a washing machine including a lint collecting tool that collects lint floating in a washing tub. FIG. 11 is a side sectional view of the washing machine, FIG. 12 is an enlarged cross-sectional view of the main part of the washing machine, and FIG. 13 is an exploded perspective view of the main part of the washing machine. As shown in FIGS. 11 to 13, the lint collecting tool 20 described in Patent Document 1 is composed of one filter 21 made of a net bag and a frame 22 that borders the mouth of the filter 21, By fitting the shaft portion 23 projecting from the lower center and upper center of the frame 22 into the shaft hole 25a of the filter mounting base 25 fixed to the inner surface of the washing tub 24, the shaft portion 23 is left and right. Mounted so that it can swing.

  As shown in FIG. 12, when the washing water in the washing tub flows in the arrow Y direction in the vicinity of the lint collecting tool 20, the filter 21 is rotated counterclockwise around the shaft portion by the water flow. Thus, the opening of the filter 21 is opened on the upstream side of the water flow, and the washing water and the yarn waste flowing in the washing tub 24 can be taken into the filter 21. Therefore, yarn waste can be captured regardless of the direction of the water flow.

JP 7-185192 A (see paragraph 0017)

  However, the above-mentioned lint collecting tool has a problem that lint once captured flows back to the outside of the filter depending on the water level, water flow, and the state of the filter. In view of the above problems, an object of the present invention is to provide a lint collecting tool that can prevent backflow of lint.

  In order to achieve the above object, the present invention is a yarn waste collecting tool attached to a washing tub, and is configured to collect the yarn waste by collecting the yarn waste of the washing tub into the inside through an opening. A bag-shaped lint collecting filter having water permeability, and a bag-shaped check having water permeability provided on the outside of the lint collecting filter and provided with a communication opening so as to communicate with the inside of the lint collecting filter And a filter.

  The lint that has flowed into the lint collecting filter from the opening flows into the check filter that communicates with the lint collecting filter so that lint is collected in two stages: lint collecting filter and check filter. Can be captured. Therefore, the yarn waste can be prevented from flowing out of the yarn waste collecting filter.

Non-return (prevention of backflow) is to prevent the lint from flowing out of the non-return filter, and largely to prevent lint from flowing out of the lint collecting filter. It is a concept that includes. The principle of the check mechanism of the check filter includes the following two modes.

1. Non-return mechanism by buoyancy When the check filter is installed above the lint collection filter, or the back side of the check filter bag body does not have to be installed above, the back of the check filter communicates with the lint collection filter. When it is provided so as to be positioned higher in the horizontal direction than the opening, the yarn waste is lifted by its buoyancy and stays at the back side of the check filter, so that it is difficult to flow out of the check filter. Accordingly, it is possible to prevent the yarn waste from flowing backward.

2 . Check structure depending on the position of the check filter opening When the opening surface of the check filter communication opening is not parallel to the opening surface of the lint collecting filter opening, the check filter has a complicated structure. Therefore, it becomes difficult for the lint to flow out of the check filter or the lint collecting filter. Accordingly, it is possible to prevent the yarn waste from flowing backward. It should be noted that both the ease of the flow of yarn waste from the yarn waste collection filter into the check filter and the difficulty of the discharge of yarn waste from the check filter to the yarn waste collection filter must be achieved. In consideration, it is preferable that the opening surface of the communication opening of the check filter and the opening surface of the opening portion of the lint collecting filter have a perpendicular relationship.

  When fixing the lint collecting tool to the washing machine, it is preferable to provide a frame that supports the lint collecting filter and to removably support the frame on the inner surface of the washing tub. By providing the frame, the opening shape of the lint collecting filter can be maintained. Moreover, the inside of a filter can be easily cleaned by making a frame body removable from a washing tub. Furthermore, it is preferable that the lint collecting filter is detachably supported by the frame. By removing it from the frame, it becomes easier to clean the inside of the filter.

  Moreover, it is preferable to provide the frame so as to be rotatable in the circumferential direction of the washing tub. Since the frame is provided so as to be rotatable in the circumferential direction of the washing tub, the opening of the lint collecting filter can always be directed to the upstream side of the water flow in the washing tub, and the lint is collected together with the washing water. Can be led into a collecting filter. The washing tub is a concept including a washing / dehydrating tub.

  The check filter may be provided at any position on the outer surface side of the lint collecting filter as long as the check filter communicates with the inside of the lint collecting filter. It is preferable to provide a communication opening with the collecting filter. Since the lint that has flowed into the lint collecting filter floats by its buoyancy, it can easily flow into the check filter. In addition, the yarn buoyancy makes it difficult for the yarn to flow out of the check filter, thereby preventing the yarn waste from flowing back. In order to allow the check filter to communicate with the inside of the lint collecting filter, an opening different from the opening for taking in lint from the washing tub is provided in a part of the lint collecting filter, and the opening is non-returned. What is necessary is just to provide it so that it may be covered with the opening of a filter.

  When the check filter is not provided above the lint collecting filter, the back side of the check filter bag body is positioned above the communication opening of the check filter with the lint collecting filter in the vertical direction. Thus, it is preferable to extend the check filter by bending it. This is because the yarn waste that has flowed into the yarn waste collecting filter accumulates on the back side of the check filter due to its buoyancy, and does not easily flow out from the check filter.

  The check filter material is not limited as long as it has a water-permeable bag shape, but preferably has a higher buoyancy than the lint collecting filter. In the vertical direction, the back side of the yarn waste collecting filter is likely to be positioned above the communication opening with the yarn waste collecting filter, and the yarn waste in the check filter is less likely to flow backward. In order to give the check filter a higher buoyancy than the lint collection filter, a material having a specific gravity smaller than that of the lint collection filter material may be used for the check filter, You may attach a thing with big buoyancy.

  The shape of the check filter is not limited as long as it is a bag-like shape, but preferably, by reducing the cross-sectional area of the communication opening with the lint collecting filter from the cross-sectional area on the back side, It becomes difficult for the lint in the check filter to flow out.

  The check filter may be formed integrally with the lint collecting filter, but is preferably removable from the lint collecting filter. By separating the lint collecting filter and the check filter, the lint prevention filter and the check filter can be easily cleaned. The means for detachably attaching the check filter to the lint collecting filter is not limited. For example, the lint collecting filter and the opening of the check filter may be formed with a hook-and-loop fastener, a slide fastener, a button, Removably connect with a zipper.

  According to the present invention, the yarn waste that has flowed into the yarn waste collection filter flows into the check filter that communicates with the inside of the yarn waste collection filter, whereby the yarn waste is collected in two stages: the yarn waste collection filter and the check filter. Since the waste can be captured, the waste yarn can be prevented from flowing out of the waste thread collecting filter.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
<First Embodiment>
1 is a schematic side sectional view of the washing machine of the present embodiment, FIG. 2 is a side view showing a state in which the lint collecting tool is removed from the collecting tool mounting base, and FIG. 3 is a yarn provided on the inner surface of the washing and dehydrating tub. It is a front view of a waste collection tool. In FIG. 2, only the collector mounting base is shown in a sectional view. In FIG. 3, the lint collecting filter and the check filter are indicated by broken lines.

  The washing machine of the present embodiment is a washing machine provided with a lint collecting tool 1. Specifically, as shown in FIG. 1, as shown in FIG. The water tank 3 elastically supported in the figure), the washing / dehydration tank 4 supported by the tank shaft 4a so as to be horizontally rotatable in the water tank 3, and the collector provided on the inner surface of the washing / dehydration tank 4 A mounting base 5, a lint collecting tool 1 detachably fixed to the collecting tool mounting base 5, a pulsator 6 supported by a pulsator shaft 6a so as to be horizontally rotatable in the washing and dehydrating tank 4, and a water tank 3 is provided with a washing motor 7a provided at a lower portion. The washing motor 7a selectively transmits the driving force to the tank shaft 4a at the time of dehydration and to the pulsator shaft 6a at the time of washing through the speed reducing mechanism 7b with a clutch function.

  As shown in FIGS. 2 and 3, the lint collecting tool 1 includes a bag-shaped lint collecting filter 8 that has water permeability and collects lint, and washing and unloading of the lint collecting filter 8. Synthetic resin-made annular collection frame 9 attached to the opening edge of opening 8a with water tub 4, and the opening direction of opening 8a to washing and dewatering tub 4 and substantially the same as that provided on the back side thereof A synthetic resin-made annular upper opening frame 10 provided at the upper opening edge of the lint collecting filter 8 that opens in the vertical direction, and provided on the upper opening frame 10 for the backflow of lint. A non-return filter 11 having water permeability to be prevented and a synthetic resin-made annular non-return frame 12 attached to an opening edge of a communication opening 11a of the non-return filter 11 with a lint collecting filter 8 are configured. The The check frame 12 has a size inscribed in the collection frame 9.

  The lint collecting filter 8 is formed in a bag shape with a fine mesh filter material. In addition, as the lint collecting filter 8, a woven fabric or a non-woven fabric having water permeability can be adopted in addition to the net body. Nylon is used as the material for the yarn waste collecting filter 8, but other synthetic resins, natural fibers, metals, non-metals, composite materials, and the like can be used. However, the present invention is not limited to this.

  An upper opening for connecting the check filter 11 is formed in the upper part of the yarn waste collecting filter 8. The position of the upper opening may be formed at any position above the yarn waste collecting filter 8, but in the present embodiment, it is formed on the back side of the yarn waste collecting filter 8. If the check filter 11 is connected to this position, the upper fixing part 17 of the collector mounting base 5 described later does not get in the way.

  The check filter 11 is formed in a bag shape by a fine mesh-like filter material. As the non-return filter 11, a woven fabric or a non-woven fabric having water permeability can be adopted in addition to the net body. Nylon is used as a material for the check filter 11. The material is not limited to nylon, and other materials such as synthetic resin, natural fiber, metal, nonmetal, and composite material can be used. Further, the check filter 11 may be made of the same material as that of the lint collecting filter 8, but it is preferable to use a material having a buoyancy larger than that of the lint collecting filter 8. In addition, it is good also as a structure which attaches another member with buoyancy, such as a float, to a non-return filter instead of giving buoyancy to the raw material itself of the non-return filter 11 in this way.

  The upper opening frame body 10 of the lint collecting filter 8 and the check frame body 12 of the check filter 11 are provided with locking means (not shown) for detachably locking each other. 11 is detachably fixed to the lint collecting filter 8. In the present embodiment, a convex claw (not shown) is provided on the outer surface of the check frame 12, and is locked at a position facing the claw of the check frame 12 on the inner surface of the upper opening frame 10. A hole (not shown) is formed. By fitting the claw and the locking hole, the upper opening frame body 10 and the check frame body 12 can be engaged. It can also be removed easily. In contrast to this, a convex claw may be provided on the inner surface of the upper opening frame 10 to form a locking hole in the check frame 12. By making the upper opening frame body 10 and the check frame body 12 detachable, the check filter 11 can be detachably attached to the lint collecting filter 8.

  Further, the collection frame 9 has an upper extension plate 13 that protrudes upward from the upper surface thereof and then bends to the washing tub 4 side, and a lower portion that protrudes downward from the lower surface and then is bent to the washing tub 4 side. An extension plate 14 is provided. The tips of the upper extension plate 13 and the lower extension plate 14 protrude toward the washing tub 4 side. A shaft portion 15 that protrudes upward and downward is formed at the central portion of the tip of the upper extension plate 13 and the lower extension plate 14, respectively. The shaft portion 15 is detachably fitted into a shaft hole 18a and a groove 17a of the collector mounting base 5 described later, and the upper extension plate 13 and the lower extension plate 14 are formed to protrude toward the washing tub 4 side. Therefore, the lint collecting tool 1 can be freely rotated in the circumferential direction of the washing and dewatering tub 4.

  The collector mounting base 5 is composed of a plate-shaped mounting base body 16, and an upper fixing part 17 and a lower fixing part 18 that protrude from the upper end and lower end of the mounting base body 16 toward the shaft side of the washing and dewatering tub 4. Then, it is fixed to the inner surface of the washing and dewatering tank 4 with fixing means (not shown) such as screws. A groove 17a extending in the radial direction of the washing / dehydrating tub 4 is formed on the lower surface of the upper fixing portion 17, and a shaft hole 18a is formed in the lower fixing portion 18. The shaft portion 15 below the collection frame body 9 is inserted into the shaft hole 18 a of the lower fixing portion 18, and the shaft portion 15 above the collection frame body 9 is fitted into the groove 17 a of the upper fixing portion 17. The collection frame 9 is pivotally supported by the collector mounting base 5. In addition, when fitting the collection frame body 9, since the shape of the upper extension board 13 and the lower extension board 14 shows an effect | action like a cushion, it can attach easily. Further, as shown in FIG. 3, the mounting base body 16 has a horizontal direction (washing and dewatering tub 4) from its left and right ends (circumferential ends of the washing and dewatering tub 4) to the attachment position of the lint collecting filter 8. A plurality of raised flow ribs 19 are integrally formed at substantially equal intervals along the circumferential direction. The space between the adjacent flow ribs 19 acts as a water conduit 19 a, and the water in the washing and dewatering tub 4 can be guided along the flow rib 19 to the lint collecting filter 8.

  In the above configuration, the lint collecting tool 1 includes a check filter 11 disposed outside the upper opening of the lint collecting filter 8, and the check frame is inserted into the locking hole formed in the upper opening frame body 10. Assembling is performed by fitting the claws formed on the outer surface of the body 12. The yarn waste collecting tool 1 assembled in this way inserts the shaft part 15 below the collecting frame body 9 into the shaft hole 18a of the lower fixing part 18 of the collecting tool mounting base 5, and collects the collecting frame body. The yarn waste collecting tool 1 is fixed to the collecting tool mounting base 5 by fitting the shaft portion 15 above 9 into the groove 17 a of the upper fixing portion 17 of the collecting tool mounting base 5. The fixed lint collecting tool 1 is fixed to the shaft portion 15 above and below the collecting frame 9 so that the shaft can rotate.

  When a water flow is generated in the washing and dewatering tub 4 at the time of washing, the side surface of the yarn waste collecting tool 1 receives the water flow, and the yarn waste collecting device 1 directs the opening of the opening 8a toward the upstream side of the water flow. The axis rotates. A large amount of washing water flows into the lint collecting filter 8 together with lint. Since the yarn waste that has flowed up is lifted by its buoyancy, it flows into the check filter 11 that is located above the yarn waste collection filter 8 and communicates with the inside of the yarn waste collection filter 8. The lint that has flowed into the check filter 11 is unlikely to flow back from the check filter due to its buoyancy.

  When cleaning the lint collecting tool 1, the lint collecting tool 1 is removed from the collecting tool mounting base 5, and the upper opening frame 10 of the lint collecting filter 8 and the check frame 12 of the check filter 11 are removed. Can be disassembled into the lint collecting filter 8 and the check filter 11 and can be easily cleaned.

  In the above embodiment, the check filter 11 is detachably provided on the yarn waste collecting filter 8, but the check filter 11 is formed integrally with the yarn waste collecting filter 8 as shown in FIG. May be.

<Second Embodiment>
FIG. 5 is a side view showing a state where the lint collecting tool of the second embodiment is detached from the collecting tool mounting base. As shown in FIG. 5, the present embodiment is characterized in that the shape of the check filter is formed in a substantially T shape in front view so that the cross-sectional area on the back side is larger than the cross-sectional area of the opening 8a. The other basic configuration is the same as that of the first embodiment.

  The check filter 11 is formed in a substantially T shape in front view so that the cross-sectional area on the back side is larger than the cross-sectional area of the communication opening 11 a connected to the yarn collection filter 8. The check filter 11 is arranged such that the lower end of the wide portion 11b on the back side of the check filter 11 is located above the upper fixing portion 17 when the lint collecting tool 1 is attached to the collecting tool mounting base 5. It is formed.

  By making the check filter 11 into a substantially T-shape when viewed from the front, the cross-sectional area of the communication opening 11a with the lint collecting filter 8 is smaller than the cross-sectional area on the back side, and the check filter 11 is a complicated structure having a step in the interior, the yarn waste once captured in the check filter 11 is unlikely to flow out of the check filter 11. Moreover, since the volume of the non-return filter 11 becomes large, the amount of yarn waste captured increases. Moreover, since the wide part 11b of the upper side of the non-return filter 11 is located above the upper fixture 19 of the collector mounting base 5, even if the non-return filter 11 is pushed downward by a water flow, the wide part 11b. Is caught on the upper fixture 19, the yarn waste in the check filter 11 is less likely to flow backward. Therefore, it is preferable to extend the end of the wide portion 11b on the washing tub side to the extent that it covers most of the upper portion of the upper fixture 19.

  In the above embodiment, the check filter 11 is detachably provided on the yarn waste collecting filter 8, but the check filter 11 is formed integrally with the yarn waste collecting filter 8 as shown in FIG. May be.

<Third Embodiment>
FIG. 7 is a side view showing a state where the lint collecting tool of the third embodiment is removed from the collecting tool mounting base. As shown in FIG. 7, in the present embodiment, the check filter 11 is provided on the side here other than above the lint collecting filter 8, and other basic configurations Is the same as in the first embodiment.

  A lateral opening for connecting the check filter 11 is formed on the back side of the yarn waste collecting filter 8. The position of the side opening may be formed at any position on the side of the yarn waste collecting filter 8.

  The check filter 11 is formed to be bent in an L shape so that the back side of the bag body is located above the communication opening 11a with the lint collecting filter in the vertical direction. In addition, as shown in FIG. 9, the thing which has buoyancy, such as the float 11c, is provided in the back | inner side of the non-return filter 11, or the back | inner side of the non-return filter 11 is fixed to the lint collecting filter 8. The back side of the check filter 11 may be positioned upward in the vertical direction.

  The back side of the check filter 11 is once captured in the check filter 11 by being positioned higher in the vertical direction than the communication opening 11a of the check filter 11 with the lint collecting filter 8. Due to the buoyancy, the lint that has been collected accumulates on the back side of the check filter 11 and hardly flows out of the check filter 11. Therefore, backflow of yarn waste can be prevented.

  In the above embodiment, the check filter 11 is detachably provided on the yarn waste collecting filter 8, but the check filter 11 is formed integrally with the yarn waste collecting filter 8 as shown in FIG. May be.

  Moreover, in the said embodiment, although the non-return filter 11 was provided so that the communication opening 11a might be formed in the side of the yarn waste collection filter 8, as shown in FIG. You may provide so that the communication opening 11a may be formed in the opening surface to the dehydration tank 4 substantially perpendicularly below. What is necessary is just to form in U shape so that the back | inner side of the non-return filter 11 may be located upwards in the perpendicular direction rather than the communicating opening 11a with the yarn waste collection filter 8.
