The lint filter 30 in the filter case 21 is arranged between the inflow port 213 and the outflow port 214 and the drainage port 215. As a result, the lint filter 30 exerts a filter function for the washing water (circulating water) flowing from the inflow port 213 to the outflow port 214 during washing, and the washing water (washing water) flowing from the inflow port 213 to the drainage port 215 at the time of drainage. It can exert a filter function for wastewater).

FIG. 4 is a perspective view showing a specific configuration of the lint filter 30 according to the first embodiment, (a) shows a state of being housed in the filter case 21, and (b) is taken out from the filter case 21. Shows the state when removing the accumulated dust.

The lint filter 30 is composed of a filter main body 31 and a movable member 32. FIG. 5A is a perspective view of the filter main body 31, and FIG. 5B is a perspective view of the movable member 32. The filter main body 31 is composed of a base portion 311 inserted into the knob member 22 and a filter portion 312 extending rearward from the base portion 311. The filter portion 312 is a bottomed filter portion having an opening at the upper side, and at least the side surface and the rear surface are the filter surfaces. Specifically, the bottom surface of the filter unit 312 is a grid-like filter, and the side surface and the rear surface are rib-like filters composed of a plurality of ribs extending in parallel in the vertical direction (vertical direction). In the filter section 312, the ribbed filter surface is provided toward the outflow port 214 and the drainage port 215, and the opening is provided toward the inflow port 213.

The movable member 32 can be fitted into the filter unit 312 from above, and moves up and down along the filter surface of the filter unit 312 (more specifically, along the ribs on the side surface and the rear surface of the filter unit 312). It can slide parallel to the direction. Therefore, a plurality of grooves (or holes) are formed around the movable member 32 so as to mesh with the ribs of the filter portion 312. When the lint filter 30 is housed in the filter case 21, the movable member 32 is pushed downward so as to come into contact with the bottom surface of the filter portion 312, as shown in FIG. 4A.

When the filter unit 20 is used (during washing or draining), the washing water flowing from the inflow port 213 of the filter case 21 flows from above the filter unit 312, and the filter surfaces (bottom surface, side surface and rear surface) of the filter unit 312. ), And flows out from the outlet 214 or the drain 215 of the filter case 21. At this time, dust such as lint mixed in the washing water is collected on the filter surface of the filter unit 312. Further, the collected dust will be collected on the upper surface side of the movable member 32.

When removing the dust accumulated in the filter unit 20, the lint filter 30 is pulled out from the filter case 21, and the movable member 32 is pulled upward as shown in FIG. 4B. At this time, in the movable member 32, the portion provided between the ribs of the filter portion 312 serves as a guide portion for guiding the movement of the filter portion 312 along the ribs. Since the dust collected by the lint filter 30 is collected on the upper surface side of the movable member 32, dust such as lint adhering to the ribs of the filter portion 312 can be scraped off and collected by the action of pulling up the movable member 32. Therefore, dust can be easily removed from the lint filter 30 simply by turning the lint filter 30 over. At this time, the user does not need to touch the dust accumulated in the lint filter 30 in the operation of pulling up the movable member 32.

That is, the movable member 32 of the lint filter 30 can remove dust between the ribs by moving the guide portion provided between the ribs of the filter portion 312 along the ribs. Further, since the guide portion is provided between the ribs, the movable member 32 is prevented from being deformed or dropped. It is preferable that the movable member 32 has a handle portion 321 that projects outward from the side surface of the filter portion 312. By providing the handle portion 321 on the movable member 32, the user can easily move the movable member 32.

In the above description, the case where the lint filter 30 is composed of the filter main body 31 and the movable member 32 has been illustrated. However, the present invention is not limited to this, and instead of the movable member 32, the movable member 33 shown in FIG. 5 (c) and the movable member 34 shown in FIG. 5 (d) can be used.

The movable member 32 shown in FIG. 5B has a configuration that does not have a filter surface by itself. On the other hand, the movable member 33 shown in FIG. 5C is configured to have a filter surface itself. As a result, the movable member 33 does not impair the filter function of the grid-like filter on the bottom surface of the filter unit 312 of the filter body 31.

Further, the movable member 32 has an outer frame portion 322 around the movable member 32, and each rib on the side surface and the rear surface of the filter main body 31 has an engaging projection 313 protruding outward at the tip thereof. In this configuration, as shown in FIG. 4B, when the movable member 32 is pulled upward, the outer frame portion 322 of the movable member 32 is caught by the engaging projection 313, and the movable member 32 comes off from the filter main body 31. Can be prevented. On the other hand, the movable member 34 shown in FIG. 5D has a structure having no outer frame portion around the movable member 34, and the movable member 34 can be easily removed from the filter main body 31. .. In this configuration, the dust accumulated in the lint filter 30 can be more reliably removed by the operation of removing the movable member 34 from the filter main body 31.

Further, the lint filter 30 according to the first embodiment may be composed of the filter main body 35 and the movable member 36 shown in FIGS. 6A and 6B. The lint filter 30 shown in FIGS. 6A and 6B is a filter body 35 in which the engaging protrusions are eliminated from the tips of the ribs on the side surface and the rear surface. Even in this configuration, the movable member 36 can be easily removed from the filter main body 35.

In the second embodiment, the structure of the lint filter different from that of the first embodiment will be described. FIG. 7 is a perspective view showing a specific configuration of the lint filter 40 according to the second embodiment, (a) shows a state of being housed in the filter case 21, and (b) is taken out from the filter case 21. Shows the state when removing the accumulated dust. In the second embodiment, the lint filter 40 is used instead of the lint filter 30 in the first embodiment, but the same filter case 21 and the knob member 22 as those in the first embodiment are used.

The lint filter 40 according to the second embodiment is composed of a filter main body 41 and a movable member 42. FIG. 8A is a perspective view of the filter main body 41, and FIG. 8B is a perspective view of the movable member 42. The filter main body 41 is composed of a base portion 411 inserted into the knob member 22 and a filter portion 412 extending rearward from the base portion 411. The filter portion 412 is a bottomed filter portion having an opening at the upper side, and at least a side surface and a rear surface thereof are used as filter surfaces. Specifically, the bottom surface of the filter unit 412 is a grid-like filter, and the side surface and the rear surface are rib-like filters composed of a plurality of ribs extending in the vertical direction. However, the ribs on the side surface extend substantially in the vertical direction, and are actually formed concentrically with respect to the rotation fulcrum A described later.

The movable member 42 can be fitted into the filter portion 412 from above, and has rotating protrusions 421 on both side surfaces of the front end portion of the movable member 42. On the other hand, the filter main body 41 has a rotation hole 413 for fitting the rotation protrusion 421. When the movable member 42 is fitted into the filter portion 412, the rotating protrusion 421 fits into the rotating hole 413 to form a rotating fulcrum A, and the movable member 42 is centered on the rotating fulcrum A and It is rotatable in the vertical direction along the filter surface of the filter unit 412 (more specifically, along the ribs on the side surface and the rear surface of the filter unit 412). When the lint filter 40 is housed in the filter case 21, the movable member 42 is pushed downward so as to come into contact with the bottom surface of the filter portion 412, as shown in FIG. 7A.

Even in the lint filter 40 according to the second embodiment, dust such as lint mixed in the washing water is collected on the filter surface of the filter unit 412, and the collected dust is collected on the upper surface side of the movable member 42. It will be.

When removing dust accumulated in the filter unit 20, the lint filter 40 is pulled out from the filter case 21 and the movable member 42 is rotated upward as shown in FIG. 7B. At this time, in the movable member 42, the portion provided between the ribs of the filter portion 412 serves as a guide portion for guiding the movement of the filter portion 412 along the ribs. Since the dust collected by the lint filter 40 is collected on the upper surface side of the movable member 42, dust such as lint adhering to the rib of the filter portion 412 is scraped off by the operation of rotating the movable member 42 upward. The dust can be easily removed from the lint filter 40 simply by turning over the lint filter 40. At this time, the user does not need to touch the dust accumulated in the lint filter 40 in the operation of rotating the movable member 42.

In the lint filter 40 according to the second embodiment, since the movable member 42 rotates and moves around the rotation fulcrum A, the amount of movement is at a position away from the rotation fulcrum A (that is, near the rear end). Is large, and the amount of movement is small at a location near the rotation fulcrum A (that is, near the front end). On the other hand, in the filter case 21, the outlet 214 is provided near the middle in the front-rear direction, and the drain port 215 is provided near the rear end. For this reason, most of the dust collected by the filter unit 412 is collected from the middle of the filter unit 412 to the vicinity of the rear end portion, and as described above, the amount of movement of the movable member 42 is large near the rear end portion. If so, it is easy to remove the dust.

In the above description, the case where the lint filter 40 is composed of the filter main body 41 and the movable member 42 has been illustrated. However, the present invention is not limited to this, and the movable member 43 shown in FIG. 8C can be used instead of the movable member 42.

The movable member 42 shown in FIG. 8B has a configuration that does not have a filter surface by itself. On the other hand, the movable member 43 shown in FIG. 8C is configured to have a filter surface itself. As a result, the movable member 43 does not impair the filter function of the grid-like filter on the bottom surface of the filter unit 412 of the filter body 41.

Further, the lint filter 40 according to the second embodiment may be composed of the filter main body 44 shown in FIG. 9A and the movable member 45 shown in FIG. 9B. The movable member 45 has lever portions 452 on both side surfaces of the front end portion, and the lever portion 452 is provided with a rotating protrusion 451. On the other hand, the filter main body 44 has a rotation hole 443 for fitting the rotation protrusion 451. When the movable member 45 is fitted into the filter main body 44, the rotating protrusion 451 fits into the rotating hole 443 to become a rotating fulcrum A. In this configuration, the fitting state of the rotating protrusion 451 and the rotating hole 443 can be released by pushing the lever portion 452 inward, and the movable member 45 can be easily pulled out from the filter main body 44. Then, by pulling out the movable member 45 from the filter main body 44, the dust accumulated in the lint filter 40 can be removed more reliably.

[Embodiment 3]
In the third embodiment, the structure of the lint filter different from the first and second embodiments will be described. 10A and 10B are perspective views showing a specific configuration of the lint filter 50 according to the third embodiment, FIG. 10A shows a state of being housed in the filter case 21, and FIG. 10B is taken out from the filter case 21. Shows the state when removing the accumulated dust. In the third embodiment, the lint filter 50 is used instead of the lint filter 30 in the first embodiment, but the same filter case 21 and the knob member 22 as those in the first embodiment are used.

The lint filter 50 according to the third embodiment is composed of a filter main body 51 and a movable member 52. The lint filter 50 shown in FIG. 10 is shown as a modification of the lint filter 30 shown in FIG.

The filter body 51 is not only a rib-shaped filter having a plurality of ribs whose side surface and rear surface are extended in the vertical direction, but also a plurality of collectors inside the filter surface near the rear end portion. It has a rib 511.

As described in the second embodiment, most of the dust collected by the filter portion of the lint filter is collected from the middle to the rear end of the filter portion. The collection rib 511 in the filter main body 51 has an effect of retaining the collected dust only in the vicinity of the rear end portion and reducing the dust accumulated in the vicinity of the middle portion of the filter portion. This makes it possible to prevent the outlet 214 of the filter case 21 from being blocked by the accumulated dust and hindering the circulation of the washing water, particularly during washing with the drum-type washing machine 10.

[Embodiment 4]
In the fourth embodiment, the structure of the lint filter different from the first to third embodiments will be described. 11A and 11B are perspective views showing a specific configuration of the lint filter 60 according to the fourth embodiment, FIG. 11A shows a state of being housed in the filter case 21, and FIG. 11B is taken out from the filter case 21. Shows the state when removing the accumulated dust. In the fourth embodiment, the lint filter 60 is used instead of the lint filter 30 in the first embodiment, but the same filter case 21 and the knob member 22 as those in the first embodiment are used.

The lint filter 60 according to the fourth embodiment is composed of a filter main body 61, a movable member 62, and an opening / closing member 63. The filter portion 611 in the filter main body 61 is a bottomed filter portion with an opening at the upper side and a rear side, and at least a side surface thereof is a filter surface. Specifically, the filter surface of the filter unit 611 is a rib-shaped filter composed of a plurality of ribs extending in the front-rear direction (horizontal direction).

The movable member 62 can be fitted into the filter portion 611 from the rear, and can slide parallel to the front-rear direction along the rib on the side surface of the filter portion 611. When the lint filter 60 is housed in the filter case 21, the movable member 62 is located on the front side with respect to the filter portion 611, as shown in FIG. 11A.

The opening / closing member 63 is attached to the rear end portion of the filter portion 611, and opens / closes the rear end portion of the filter portion 611. When the lint filter 60 is housed in the filter case 21, the opening / closing member 63 closes the rear end of the filter portion 611, as shown in FIG. 11A. In FIG. 11, the opening / closing member 63 itself has a filter surface, but the opening / closing member 63 may not have a filter surface.

When the filter unit 20 is used (during washing or draining), the washing water flowing from the inflow port 213 of the filter case 21 flows from above the filter unit 611, and the filter surface (or opening / closing member 63) of the filter unit 611 It passes through the filter surface) and flows out from the outlet 214 or the drain 215 of the filter case 21. At this time, dust such as lint mixed in the washing water is collected on the filter surface of the filter unit 611 (or the filter surface of the opening / closing member 63). Further, the collected dust will be collected on the rear side of the movable member 62.

When removing dust accumulated in the filter unit 20, the lint filter 60 is removed from the filter case 21, the opening / closing member 63 is opened, and the movable member 62 is filtered by the filter unit 611 as shown in FIG. 11B. It is moved rearward along the surface (more specifically, along the ribs on the side surface of the filter unit 611). Since the dust collected by the lint filter 60 is collected on the rear side of the movable member 62, dust such as lint adhering to the rib of the filter portion 611 is scraped by the operation of moving the movable member 62 from the front to the rear. It can be collected and collected, and dust can be easily removed from the lint filter 60 simply by turning the rear end of the lint filter 60 downward. At this time, in the movable member 62, the portion provided between the ribs of the filter portion 611 serves as a guide portion for guiding the movement of the filter portion 611 along the ribs. The user does not need to touch the dust accumulated in the lint filter 60 in the operation of moving the movable member 62.

Further, although not shown in FIG. 11, the movable member 62 may also be provided with a handle portion that protrudes outward from the filter surface of the filter portion 611. Such a handle portion may be retrofitted to the movable member 62 (after the movable member 62 is attached to the filter main body 61, the handle portion is attached to the movable member 62 from the outside of the filter surface). In this case, not only the movable member 62 can be easily moved by the handle portion, but also the rib of the filter portion 611 is reinforced.

[Modification example]
In the above-described first to fourth embodiments, the movable member is an integral member composed of one component, and such an integral member can be formed of resin. However, if the movable member 32, 36, 42, 52, 62 does not have a filter surface in particular, it is possible to use this as a combination member composed of two parts.

Taking the movable member 42 as an example, as shown in FIG. 12A, the movable member 42 can be composed of a base component 42A and a cover component 42B covering the base component 42A. Taking the movable member 62 as an example, as shown in FIG. 12B, the movable member 62 can be composed of a base component 62A and a cover component 62B covering the base component 62A. In this case, the materials of the base component 42A or 62A and the cover component 42B or 62B can be different. For example, the base component 42A or 62A can be made of resin and the cover component 42B or 62B can be made of rubber. By using rubber for the cover component 42B or 62B, the groove portion that meshes with the rib of the filter portion 412 or 611 can be easily brought into close contact with the rib, and dust adhering to the rib can be easily scraped off. Further, the combination of different materials may be handled by a two-color molded product in which the shape of the scraped portion is rubber, in addition to the combination of two parts.

Further, in the above-described first to fourth embodiments, when the lint filter is housed in the filter case 21, the movable member needs to be moved to a predetermined initial position. However, after the user moves the movable member to remove dust from the lint filter, it is conceivable that the lint filter is attached to the filter case 21 by forgetting to return the movable member to the original initial position.

On the other hand, it is conceivable that the lint filter cannot be housed in the filter case 21 when the movable member has not been returned to the initial position. As a specific example, taking the lint filter 30 of FIG. 4 as an example, a state in which the restricting portion 216 protruding in a flange shape is provided on the inner wall of the filter case 21 and the movable member 32 is not returned to the initial position (for example, FIG. In the state of b)), the handle portion 321 of the movable member 32 (that is, the portion protruding outward from the side surface of the filter portion 312) comes into contact with the regulation portion 216, and the lint filter 30 cannot be inserted into the filter case 21. It is conceivable (see FIG. 13 (a)). In this case, in the state where the movable member 32 is returned to the initial position (the state of FIG. 4A), the handle portion 321 does not abut on the regulation portion 216, and the lint filter 30 is inserted into the filter case 21. (See FIG. 13 (b)).

Further, as in the lint filter 60 shown in FIG. 11, if the moving direction of the movable member 62 and the insertion direction when the lint filter is inserted into the filter case 21 are the same, the lint filter is inserted into the filter case 21. It is also possible to configure the movable member 62 to return to the initial position in conjunction with the operation at the time. For example, as shown in FIG. 14, when a protrusion-shaped regulating portion 217 is provided inside the filter case 21 and the lint filter 60 is inserted into the filter case 21, the movable member 62 comes into contact with the regulating portion 217 and moves. The movable member 62 can be regulated and returned to the initial position (see FIG. 14B). This configuration also prevents the lint filter 60 from being mounted on the filter case 21 in a state where the movable member 62 is forgotten to be returned to the original initial position.
