Summary of the Invention

Problems to be Solved by the Invention

[0004] In the filter unit described in Patent Document 1 mentioned above, the user's hand may touch foreign matter, and there is room for improvement from the perspective of the cleanliness of the work. In the filter unit described in Patent Document 2, the user can perform a cleaning operation using the scraping portion of the front cover. However, it is necessary to remove the front cover, and after the operation, the user needs to assemble the unit as it was before. Also, there is a possibility that the user may mistake the scraping part, direction, etc., and there is a risk that the cleaning operation cannot be performed reliably.

[0005] An object of the present invention is to provide a washing machine capable of performing a foreign matter removal operation without touching the foreign matter, and capable of performing the maintenance work of the filter unit simply, reliably, and surely.

Means for Solving the Problems

[0006] [1] A washing machine according to an aspect of the present disclosure includes an outer tub disposed in a housing, a washing and dehydrating tub rotatably provided in the outer tub, and a lint filter unit detachably attached to the inner surface side of the side wall portion of the washing and dehydrating tub. The lint filter unit includes a back unit that allows washing water to flow in from a back surface portion facing the side wall portion, and a front cover attached to the front side of the back unit and having a filtering surface through which the washing water passes. The back unit includes a main body portion including a back opening for allowing washing water to flow in and a foreign matter accommodating portion formed in the vicinity of the back opening and capable of accommodating foreign matter contained in the washing water, and a scraping member slidably attached to the main body portion and including at least one protruding piece that scrapes out the foreign matter in the foreign matter accommodating portion as it slides.

[0007] According to the washing machine of [1], with the lint filter unit attached to the side wall of the washing and dewatering tub, during the operation of the washing machine, the washing water flows in from the back surface of the rear unit. The washing water passes through the filtering surface of the front cover. Foreign objects such as lint captured on the filtering surface remain between the front cover and the rear unit. In the dehydration process of the washing machine, the foreign objects are attracted to the main body of the rear unit by centrifugal force and are stored in the foreign object storage section. When the user performs maintenance work on the lint filter unit, the user removes the lint filter unit from the washing and dewatering tub. Then, by pulling out the scraping member from the main body, the protruding piece scrapes out the foreign objects along with the sliding operation. In this way, the user can scrape out the foreign objects simply by pulling out the slidable scraping member, and can perform the foreign object removal work without touching the foreign objects. Also, the foreign object scraping work can be performed in a state where the front cover, the main body, and the scraping member are assembled without being separated from each other. After discharging the foreign objects (and after other cleaning work), the scraping member may be pushed in and set in the main body. Therefore, it is not necessary to remove and assemble the component parts of the unit, and the maintenance work of the lint filter unit can be performed simply, reliably, and easily.

[0008] In the washing machine of the above [1], the main body has a rectangular shape with a short side and a long side, is rotatable with respect to the front cover around a rotation axis disposed at one end in the long side direction, and the scraping member may be slidable in the long side direction with respect to the main body. According to this configuration, the user can rotate the rear unit with respect to the front cover (this may be a relative rotation operation), open the rear unit, and discharge the foreign objects scraped out by the scraping member from the rear unit, for example, by dropping them, so that they can be easily discarded.

[0009] [3] In the washing machine of [2] above, the scraping member includes a gripping portion formed at the other end in the long side direction, and an engaging portion for engaging the rear unit with the front cover may be provided in the vicinity of the gripping portion. According to this configuration, slight deformation or movement of the surrounding members caused by gripping and operating the gripping portion can be easily applied to the engaging portion. Therefore, normally, the rear unit is engaged with and fixed to the front cover, and during maintenance work, the rear unit can be easily opened.

[0010] [4] In the washing machine of [2] or [3] above, the scraping member may always be slidable with respect to the main body portion regardless of whether the main body portion is rotated and opened with respect to the front cover or the main body portion overlaps and closes the front cover. According to this configuration, depending on the user's preference of usage, the amount of foreign matter, or the content of maintenance work, etc., it is possible to select whether to pull out the scraping member with the main body portion (i.e., the rear unit) open or to pull out the scraping member with the main body portion (i.e., the rear unit) closed.

[0011] [5] In any one of the washing machines of [1] to [4] above, the foreign matter accommodating portion may include a pair of narrow groove portions extending in the sliding direction adjacent to a pair of side edges of the rear opening, and a wide portion adjacent to an edge of the rear opening in the sliding direction. According to this configuration, within the limited shape and size of the main body portion, a larger (wider) accommodating space for foreign matter can be ensured. Also, since the pair of narrow groove portions and the wide portion are arranged to surround the rear opening, foreign matter can be more reliably captured in any area.

Effects of the Invention

[0012] According to the present invention, the foreign matter removal work can be performed without touching the foreign matter. Also, it is not necessary to remove and assemble the component parts of the unit, and the maintenance work of the lint filter unit can be performed simply, reliably, and.

DETAILED DESCRIPTION OF THE INVENTION

[0014] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the description of the drawings, the same reference numerals are assigned to the same elements, and redundant descriptions are omitted.

[0015] First, referring to FIG. 1, the configuration of the washing machine 1 of the present embodiment will be described. The washing machine 1 is, for example, a vertical washing machine. The washing machine 1 includes a housing (not shown). For example, an outer tub 3 (shown by a virtual line in FIG. 1) and a washing and dewatering tub 4 are arranged in a rectangular parallelepiped housing. Both the outer tub 3 and the washing and dewatering tub 4 have a bottomed cylindrical shape. The outer tub 3 is configured such that a washing liquid is supplied to the outer tub 3 and the washing liquid can be discharged from the outer tub 3. In this specification, the "washing liquid" means a liquid corresponding to each process such as the washing process and the rinsing process of the laundry. Therefore, in the washing process, the washing liquid may be a liquid containing a detergent or the like, and in the rinsing process, the washing liquid may be water.

[0016] The washing and dehydrating tub 4 is smaller than the outer tub 3 and is arranged coaxially with the outer tub 3 inside the outer tub 3. The washing and dehydrating tub 4 is provided rotatably about a rotating shaft extending in the vertical direction. The washing and dehydrating tub 4 is, for example, a tub made of metal. The washing and dehydrating tub 4 washes or dehydrates the laundry put into the washing and dehydrating tub 4. A balancer 5 for reducing vibration is provided at the opening at the upper part of the washing and dehydrating tub 4. A plurality of through holes (not shown) are formed in the side wall portion 4a of the washing and dehydrating tub 4. Thereby, the washing liquid can flow back and forth between the outer tub 3 and the washing and dehydrating tub 4. A rotary vane (pulsator) 6 is rotatably arranged at the bottom of the washing and dehydrating tub 4.

[0017] A drive unit (not shown) is installed in the housing. The drive unit having a drive motor and a clutch mechanism etc. rotates only the rotary vane 6, or rotates both the rotary vane 6 and the washing and dehydrating tub 4. By the switching operation by the clutch mechanism, only the rotary vane 6 is rotated in the washing step and the rinsing step, and in the dehydration step, the rotary vane 6 and the washing and dehydrating tub 4 are integrally rotated. In this specification, when a symbol such as "·" is used in "washing and dehydrating tub", this symbol has the meaning of "and" or the meaning of "serving as ~".

[0018] A lint filter unit 8 is attached to the inner surface side of the cylindrical side wall portion 4a of the washing and dehydrating tub 4 at an appropriate location in the circumferential direction. A water filtering portion 7 for filtering the washing water is provided at the said location of the side wall portion 4a. The lint filter unit 8 is fitted into this water filtering portion 7. The lint filter unit 8 can release the locking to the side wall portion 4a by the operation of the clip portion 17. Thereby, the lint filter unit 8 is detachably attached to the inner surface side of the side wall portion 4a.

[0019] Inside the water filtration section 7, a circulation water path (not shown) for circulating the washing water is formed. The circumferential water flow generated during the rotation of the rotary blade 6 flows into the water filtration section 7 from the inflow section 9 provided on the side surface of the water filtration section 7. The washing water that has flowed into the water filtration section 7 is introduced into the lint filter unit 8 from the back surface portion 21 (more specifically, the back opening 32; details will be described later) of the lint filter unit 8. Note that the configurations of the water filtration section 7 and the inflow section 9 are not limited to the above. As a structure for allowing the washing water to flow in and a structure for circulating the washing water, another known configuration may be adopted. For example, a configuration in which the washing water is pumped up by the pumping blades provided on the lower surface of the rotary blade 6 may be adopted.

[0020] The lint filter unit 8 captures foreign matters such as lint contained in the washing water that flows into the water filtration section 7 and circulates through the circulation water path. The lint filter unit 8 will be described with reference to FIGS. 1 to 3. As shown in FIGS. 1 and 2, the lint filter unit 8 generally has a rectangular shape when viewed from the front (front side). The lint filter unit 8 includes a front cover 10 having a filtration surface F through which the washing water passes. The lint filter unit 8 has a flat structure, and by covering the water filtration section 7, a structure that is somewhat watertight with respect to the side wall portion 4a except for the filtration surface F is formed.

[0021] The front cover 10 is exposed and faces the inner surface (the accommodation space for the laundry) of the washing and dehydrating tub 4 in a state where the lint filter unit 8 is attached to the washing and dehydrating tub 4. The front cover 10 has a rectangular plate-shaped front panel portion 11. With the first end 11a in the longitudinal direction of the front panel portion 11 facing upward and the second end 11b facing downward, the lint filter unit 8 is attached. A plurality of rectangular water passing holes 13 are formed between the first end 11a and the second end 11b. For example, a fine-mesh sheet-shaped filter (not shown) fixed to the back surface side of the front panel portion 11 and these water passing holes 13 form the filtration surface F. The filter is composed of an appropriate mesh-like material or the like. The configuration of the filtration surface F in the front cover 10 is not limited to the above.

[0022] As shown in FIGS. 2 and 3, the lint filter unit 8 includes a rear unit 20 that allows washing water to flow in from a rear surface portion 21 facing the side wall portion 4a. A rear opening 32 having a vertically long rectangular shape is formed in the rear surface portion 21 of the rear unit 20. The water filtration portion 7 is provided with a movable flap member (not shown) or the like, and the washing water is guided to the rear opening 32. The front cover 10 is attached to the front side of the rear unit 20.

[0023] With reference to FIGS. 2 to 4, the configuration of the lint filter unit 8 will be described in more detail. As shown in FIGS. 3 and 4, the rear unit 20 has a main body portion 30 including a rectangular frame body 31, and a scraping member 40 slidably attached to the main body portion 30. The scraping member 40 also includes a rectangular frame body 41 having a shape substantially overlapping the frame body 31. As shown in FIG. 4, with the main body portion 30 as a reference, a short side direction d1 and a long side direction d2 are defined. The main body portion 30 has a rectangular shape with a short side and a long side. The frame body 31 extends long in the long side direction d2, and a rear opening 32 extending long in the long side direction d2 is formed at the center thereof. The scraping member 40 is linearly slidable with respect to the main body portion 30 in the long side direction d2. Therefore, the above-described short side direction d1 and long side direction d2 are concepts that can be similarly applied to the scraping member 40 (and the entire rear unit 20).

[0024] As shown in FIG. 3, a pair of connecting portions 15 protruding toward the rear side are formed at the first end 11a of the front cover 10. Also, a pair of side plate portions 12 protruding toward the rear side are formed at the second end 11b of the front cover 10. A pair of protruding portions 36 are provided at the first end (one end) of the main body portion 30 in the long side direction d2, and a pair of shafts 35 protruding outward in the short side direction d1 are provided on each protruding portion 36. By passing these shafts 35 through shaft holes 15a formed in the connecting portions 15, the main body portion 30 is rotatable around a rotation axis L. The rotation axis L is arranged at the first end and extends in the short side direction d1 (perpendicular to the long side direction d2).

[0025] At the second end (the other end) of the scraping member 40 in the long side direction d2, a pair of gripping portions 42 are formed. In the vicinity of the gripping portions 42, an engaging convex portion 46 for engaging the scraping member 40 (rear unit 20) with the front cover 10 is provided. The engaging convex portion 46 is, for example, a protrusion having a shape corresponding to a part of a spherical surface (a low dome shape). A pair of circular engaging holes 16 capable of receiving the engaging convex portion 46 are formed in the pair of side plate portions 12 of the front cover 10. The side plate portions 12 have elasticity, and are configured such that when the user pinches and operates the pair of gripping portions 42 with the thumb and index finger, the side plate portions 12 are slightly bent outward. Note that the above-mentioned "vicinity" is, for example, within a range of a distance corresponding to the length of the scraping member 40 in the long side direction d2 of the gripping portion 42 formed according to the size of the user's finger. Since the gripping portion 42 is formed at the second end (the other end) of the main body portion 30, the engaging convex portion 46 may be formed in the region of the lower half (the second end side) of the entire length of the rear unit 20 in the long side direction d2.

[0026] When the user holds the front cover 10 with one hand and pinches and opens the gripping portion 42 with the other hand, the engaging convex portion 46 escapes from the engaging hole 16 and the rear unit 20 becomes rotatable about the rotation axis L. Conversely, when the user holds the front cover 10 with one hand, brings the other hand close to the side plate portion 12 while holding the gripping portion 42 or its vicinity, and further pushes in the rear unit 20, the engaging convex portion 46 enters the engaging hole 16 and the rear unit 20 is engaged and fixed to the front cover 10. Thus, the rotation fulcrum (rotation axis L) is provided at the upper end, and the operation portion by the user is provided at the lower end. After the user removes the lint filter unit 8 by operating the clip portion 17, the cleaning work becomes easier. When the rear unit 20 is opened, its inner surface (foreign matter storage portion A) faces downward, so the work of discarding foreign matter described later is also easy.

[0027] As shown in FIG. 4, the main body 30 includes a foreign object housing portion A formed in the vicinity of the rear opening 32. The foreign object housing portion A includes a pair of narrow groove portions 33 extending in the long side direction d2 (slide direction) adjacent to the long side ribs 38 which are a pair of side edges of the rear opening 32, and a wide portion 34 adjacent to the short side rib 39 which is an edge of the rear opening 32 in the long side direction d2. The narrow groove portions 33 are formed between a pair of long side end walls 37 disposed on the outermost side in the short side direction d1 of the frame body 31 and a pair of long side ribs 38 defining the rear opening 32. The lower end portion (downstream end portion in the direction of pulling out the scraping member 40) of the narrow groove portion 33 communicates with the wide portion 34. The lower end portion of the wide portion 34 is open. The narrow groove portions 33 have a constant rectangular cross section in the long side direction d2. The wide portion 34 has a constant rectangular cross section (a cross section larger than that of the narrow groove portion 33) in the long side direction d2.

[0028] The scraping member 40 includes a pair of rectangular protrusions 43 disposed in the pair of narrow groove portions 33 at positions corresponding to the pair of narrow groove portions 33. The scraping member 40 also includes a wide protrusion 44 disposed in the wide portion 34 at a position corresponding to the wide portion 34. In a state where the scraping member 40 is housed in the main body 30 (the initial state shown in FIG. 5 or FIG. 2), the rectangular protrusions 43 are located at the upper (first end side) end portions of the narrow groove portions 33. The wide protrusion 44 is located at the upper end portion of the wide portion 34. These rectangular protrusions 43 and wide protrusion 44 pass through the respective interiors of the narrow groove portions 33 and the wide portion 34 along with the sliding operation of the scraping member 40, and scrape out the foreign objects captured inside (see FIGS. 6 and 7).

[0029] In order to hold the posture of the scraping member 40 when the scraping member 40 is pulled out, a plurality of holding guides 47 are provided on the frame body 31. The holding guides 47 are fitted to a pair of long side end walls 37 of the main body 30 and guide the movement of the scraping member 40 in the long side direction d2. The scraping member 40 is fitted into the main body 30 by inserting the long side end wall 37 into an end opening 47a formed at the upper end.

[0030] In this embodiment, regardless of whether the scraping member 40 is in a state where the main body 30 (rear unit 20) is rotated and opened with respect to the front cover 10 (the state shown in FIG. 5) or the main body 30 (rear unit 20) overlaps and closes the front cover 10 (the state shown in FIG. 2), the scraping member 40 is slidable with respect to the main body 30. That is, the end portion on the second end 11b side of the front cover 10 is an open portion and does not inhibit the movement (pull-out) of the scraping member 40. In FIGS. 6 and 7, the scraping member 40 is pulled out in a state where the main body 30 is opened. In the state shown in FIG. 2, the user can also pick the picking portion 42 to pull out the scraping member 40 (at this time, the engaging convex portion 46 escapes from the engaging hole 16).

[0031] As shown in FIG. 7, the width W40 of the scraping member 40 in the short side direction d1 is larger than the width W30 of the main body 30 in the short side direction d1, but smaller than the width W10 of the front cover 10 in the short side direction d1. That is, in the lint filter unit 8, the width W10 of the front cover 10 is the maximum width, and in a state where the rear unit 20 is closed, the main body 30 and the scraping member 40 are within the width range of the front cover 10. Therefore, a compact configuration is realized for the entire lint filter unit 8. Also, when the lint filter unit 8 is attached to the water filtration unit 7, the rear unit 20 (main body 30 or scraping member 40) does not cause any trouble.

[0032] Furthermore, as shown in FIGS. 8(a) and 8(b), in the state where the scraping member 40 is pulled out (slid) to the maximum extent, the rectangular projection 43 reaches the lower end of the narrow groove portion 33, and the wide projection 44 has escaped from the wide portion 34. In this state where the scraping member 40 is pulled out to the maximum extent, the locking projection 49 (see also FIG. 4) formed at the first end in the long side direction d2 of the scraping member 40 abuts against the short side rib 39 that defines the rear opening 32, preventing further movement of the scraping member 40. These locking projections 49 and short side ribs 39 constitute a stopper function for preventing the scraping member 40 from falling off from the main body portion 30. Although the cross-sectional area of the narrow groove portion 33 is relatively small, a long stroke in the long side direction d2 is ensured when the rectangular projection 43 moves within the narrow groove portion 33. On the other hand, the wide projection 44 escapes from the wide portion 34 relatively earlier (compared to the rectangular projection 43), but the cross-sectional area of the wide portion 34 is large. With these configurations, the volume of the foreign matter accommodating portion A scraped by each of the projections 43, 44 (the volume of the space through which each of the projections 43, 44 passes) is sufficiently ensured.

[0033] Note that the user can remove the rear unit 20 from the front cover 10 if necessary during maintenance work. Then, with one hand holding the main body portion 30 and the other hand holding the scraping member 40, the user can release the engagement between the locking projection 49 and the short side rib 39 by moving the scraping member 40 obliquely (in a direction slightly different from the long side direction d2), and remove the scraping member 40. Unless such a conscious special removal operation is performed, the scraping member 40 is always attached to the main body portion 30 and does not come off (fall off) from the above-described slidable range.

[0034] According to the washing machine 1 of the present embodiment, while the lint filter unit 8 is attached to the side wall portion 4a of the washing and dewatering tub 4, during the operation of the washing machine 1, the washing water flows in from the back surface portion 21 of the back unit 20. The washing water passes through the filtration surface F of the front cover 10. Foreign matters such as lint trapped on the filtration surface F remain between the front cover 10 and the back unit 20. In the dehydration process of the washing machine, the foreign matters are attracted to the main body portion 30 of the back unit 20 by centrifugal force and are stored in the foreign matter storage portion A. When the user performs maintenance work on the lint filter unit 8, the lint filter unit 8 is removed from the washing and dewatering tub 4. Then, by pulling out the scraping member 40 from the main body portion 30, the protruding piece scrapes out the foreign matters along with the sliding operation. In this way, the user can scrape out the foreign matters only by pulling out the slidable scraping member 40, and can perform the removal work of the foreign matters without touching the foreign matters. Further, the foreign matter scraping work can be performed in a state where the front cover 10, the main body portion 30, and the scraping member 40 are assembled without being separated from each other. After discharging the foreign matters (and after other cleaning work), the scraping member 40 may be pushed in and set in the main body portion 30. Therefore, it is not necessary to remove and assemble the component parts of the unit, and the maintenance work of the lint filter unit 8 can be performed simply, surely, and easily.

[0035] The main body portion 30 is rotatable with respect to the front cover 10 around the rotation axis L disposed at one end in the long side direction d2, and the scraping member 40 is slidable in the long side direction with respect to the main body portion 30. Thereby, the user can rotate the back unit 20 with respect to the front cover 10 to open the back unit 20, and discharge the foreign matters scraped out by the scraping member 40 from the back unit 20, for example, by dropping them, and can easily discard them.

[0036] The scraping member 40 includes a grip portion 42 formed at the other end in the long side direction, and an engaging convex portion 46 for engaging the back unit with the front cover 10 is provided in the vicinity of the grip portion 42. Thereby, a slight deformation or movement of the surrounding members caused by gripping and operating the grip portion 42 can be easily applied to the engaging convex portion 46. Therefore, normally, the back unit 20 is engaged with and fixed to the front cover 10, and during maintenance work, the back unit 20 can be easily opened.

[0037] The scraping member 40 is always slidable with respect to the main body portion 30 regardless of whether the main body portion 30 is rotated and opened with respect to the front cover 10 or the main body portion 30 overlaps and closes the front cover 10. Thereby, according to the user's preference of usage, the amount of foreign matter, or the content of maintenance work, etc., it is possible to select whether to pull out the scraping member 40 with the main body portion 30 (that is, the back unit 20) open or to pull out the scraping member 40 with the main body portion 30 (that is, the back unit 20) closed.

[0038] The foreign matter storage portion A includes a pair of narrow groove portions 33 extending in the sliding direction adjacent to a pair of side edges of the back opening 32, and a wide portion 34 adjacent to the edge of the back opening 32 in the sliding direction. Thereby, within the limited shape and size of the main body portion 30, a larger (wider) storage space for foreign matter can be secured. Also, since the pair of narrow groove portions 33 and the wide portion 34 are arranged to surround the back opening 32, foreign matter can be more reliably captured in any area.

[0039] As described above, the embodiments of the present invention have been described, but the present invention is not limited to the above embodiments. For example, the main body portion 30 of the back unit 20 may not be configured to be rotatable with respect to the front cover 10. The main body portion 30 may have a structure that fits (such as by sliding or fitting) with respect to the front cover 10, for example.

[0040] The gripping portion 42 and the engaging convex portion 46 may be provided at completely different positions. The specific configuration of the foreign matter housing portion A is not limited to the narrow groove portion 33 and the wide portion 34 of the above embodiment, and can be appropriately deformed. The scraping projection corresponds to the cross-sectional shape of the foreign matter housing portion A, and it is sufficient that the foreign matter housing portion A is configured to allow movement or passage in the long side direction d2 (slide direction) of the projection.

[0041] The present invention is not limited to vertical washing machines, and may be applied to any type of washing machine in which the thread waste filter unit 8 is attached to the side wall portion 4a of the washing and dehydrating tub 4.
