[0008] A washing machine according to an embodiment of this disclosure will be described with reference to the drawings.

[0009] (Embodiment 1) Figure 1 is a perspective view showing a washing machine 1 according to Embodiment 1 of the present disclosure. In the following description, the front side, back side, depth direction (front-to-back direction), up-and-down direction (vertical direction), etc., refer to the directions, etc., when the washing machine 1 is installed as shown in the figure, and do not limit its usage.

[0010] The washing machine 1 according to this embodiment is a fully automatic washing machine equipped with a tub 12 inside a housing 11. In this embodiment, an example is described in which the washing machine 1 is a vertical washing machine in which the central axis of the tub is aligned in the vertical direction when installed. However, this disclosure is not limited to vertical washing machines. The washing machine according to this disclosure may be, for example, a so-called drum-type washing machine in which the tub is arranged such that, when the washing machine is installed, the central axis of the tub extends along a direction inclined with respect to the horizontal direction or the vertical direction.

[0011] Note that the washing machine generally refers to all devices that perform various processes such as washing on the laundry. Examples of the processes for the laundry include washing, drying, deodorizing, sterilizing, etc. The laundry is not particularly limited, and examples include various fabric products. Specific examples of the laundry include, for example, clothing such as clothes, hats, and gloves, belongings such as shoes, bags, handkerchiefs, and towels, bedding such as curtains, blankets, towel rugs, and futon covers, carpets, stuffed toys, etc.

[0012] The washing machine 1 includes a housing 11. The housing 11 has an internal space for accommodating the components of the washing machine 1. The housing 11 is, for example, cylindrical. Specifically, in the state where the washing machine 1 is installed, the housing 11 is cylindrical with its central axis extending along the vertical direction, opening upward, and the lower end being closed. Here, the so-called "cylindrical shape" includes shapes with both sides of the direction in which the central axis extends being open, shapes with one side of the direction in which the central axis extends being closed, and shapes with both sides of the direction in which the central axis extends being closed. The housing 11 may be, for example, circular cylindrical, oblong cylindrical, or elliptical cylindrical, but in this embodiment, it is polygonal cylindrical.

[0013] A tub 12 is arranged inside the housing 11. The tub 12 is a washing tub (rotating tub) having a cylindrical shape arranged such that its central axis extends along the vertical direction in the state where the washing machine 1 is installed. The tub 12 is provided inside a water tank (not shown) arranged inside the housing 11.

[0014] The water tank outside the tub 12 stores water, for example, when performing the washing process or the rinsing process, and is provided in a state of being substantially non-rotatable with respect to the housing 11. In contrast, the tub 12 is provided inside the water tank with an outer diameter smaller than the inner diameter of the water tank. The tub 12 has a substantially cylindrical shape with a central axis located substantially on the same straight line as the central axis of the water tank, and is rotationally driven by a drive source (not shown). An inlet 14 for loading laundry into the washing machine 1 is provided above the tub 12, and a lid 15 for opening and closing the inlet 14 is provided on the housing 11 so as to be openable and closable.

[0015] The tub 12 is configured to store washing water such as water in which detergent is dissolved or rinsing water, and is also capable of draining. At the bottom of the tub 12, a stirring blade 13 that can be rotated in both forward and reverse directions by a drive source is provided. When the stirring blade 13 of the tub 12 rotates in the forward direction, a forward water flow is generated in the tub 12, and when the stirring blade 13 rotates in the reverse direction opposite to the forward direction, a reverse water flow is generated in the tub 12. On the peripheral surface of the tub 12, a collection device 30 and a mounting portion 20 for holding the collection device 30 are provided. The washing water is configured to flow into the collection device 30 by the water flow.

[0016] The mounting portion 20 is disposed at an intermediate portion in the height direction of the tub 12. The mounting portion 20 has a shape that protrudes inward in the radial direction from the inner peripheral surface of the tub 12 and is provided to be long in the vertical direction. A groove portion 21 corresponding to the shape of the collection device 30 is provided at the central portion of the mounting portion 20, and the collection device 30 is mounted in the groove portion 21.

[0017] Above the groove portion 21 of the mounting portion 20, a recess 22 is provided to facilitate the attachment and detachment operation of the collection device 30. A plurality of ribs 23 are provided on both circumferential sides of the groove portion 21. The plurality of ribs 23 are provided at equal intervals and stand along the circumferential direction of the tub 12. These ribs 23 promote the inflow of the water flow from the circumferential direction of the tub 12 into the collection device 30.

[0018] FIG. 2 is a perspective view showing the collection device 30. The collection device 30 includes a housing 31 having a substantially rectangular box shape. The collection device 30 is attached such that the surface (front surface) disposed on the inner peripheral side X1 is exposed in the tub 12 and faces the inner side in the radial direction of the tub 12.

[0019] The housing 31 is provided with a first hole 351 that opens to one side of the circumferential direction of the tank 12, and a second hole 352 that opens to the other side of the circumferential direction of the tank 12. The second hole 352 is provided on the side opposite to the first hole 351. The first hole 351 and the second hole 352 are formed in the side wall 321 of the main body 32 and are long openings in the longitudinal direction of the housing 31. The first hole 351 and the second hole 352 communicate with the outside and inside of the housing 31, allowing the water flow from the tank 12 to circulate inside the housing 31.

[0020] Multiple mesh sections 34 are provided on the inner circumference X1 surface of the housing 31. These mesh sections 34 are configured to capture foreign matter (lint) such as lint contained in the wash water as the wash water passes through. For example, each mesh section 34 has an opening that penetrates the inside and outside of the housing 31, and is covered with a metal or resin mesh (or filter). A recess 322 is provided above the mesh section 34, allowing a finger to be hooked when attaching or detaching the collection device 30 to the mounting section 20.

[0021] Before providing a detailed explanation of the internal structure of the collection device 30 according to this embodiment, we will briefly describe an example of a conventional collection device. Figure 9 is a perspective view showing the inside of a conventional collection device 90, and Figure 10 is a cross-sectional view thereof.

[0022] The collection device 90 has a housing 91 which has a main body portion 92 and a rear portion 93. The main body portion 92 is positioned toward the inner circumference X1 of the tank, and the rear portion 93 is positioned toward the outer circumference X2 of the tank. The main body portion 92 and the rear portion 93 are constructed as separate parts and are pivotally supported via a connecting portion 94 provided at their lower ends. The housing 91 is formed in a hollow box shape, surrounded by the main body portion 92 and the rear portion 93. By rotating the rear portion 93 relative to the main body portion 92 around the connecting portion 94, the inside of the housing 91 can be exposed.

[0023] The main body portion 92 is provided with a first hole 921 and a second hole 922 on its sides. The first hole 921 and the second hole 922 are formed in the side wall 923 of the main body portion 92 as substantially rectangular notches that are elongated in the longitudinal direction of the main body portion 92 and open to the outer circumference X2. The first hole 921 and the second hole 922 become substantially rectangular openings when the back portion 93 is closed to the main body portion 92.

[0024] Inside the first hole 921 and the second hole 922, a first flap 951 and a second flap 952 are provided, respectively, as opening and closing members. The first flap 951 and the second flap 952 are arranged along the side wall 923 of the main body 92 and are provided to cover substantially the entire inner surface of the side wall 923. As shown in Figure 10, the first flap 951 and the second flap 952 are provided in a substantially L-shaped cross-section, and both ends in the Y direction are rotatably supported relative to the main body 92.

[0025] A partition member 931 is provided on the inner surface of the rear portion 93, extending toward the main body portion 92. The partition member 931 is erected along the longitudinal direction of the rear portion 93 and is integrally formed with the rear portion 93.

[0026] As shown in Figure 10, with the main body 92 and the rear part 93 closed, the partition member 931 is provided to partition the inside of the housing 91. The housing 91 is partitioned by the partition member 931 between the side with the first hole 921 and the side with the second hole 922.

[0027] In conventional designs, as shown in Figure 9, the first flap 951 and the second flap 952 are provided with multiple slits 953. The partition member 931 is also provided with multiple slits 932, forming a comb-like structure.

[0028] Wash water flows through the housing 91. Figures 11A to 11D are schematic diagrams illustrating how wash water flows through a conventional collection device 90, and show the movements of the first flap 951, the second flap 952, and the partition member 931 within the housing 91.

[0029] Figure 11A shows the state in which no washing water has flowed into the housing 91. Both the first flap 951, which is provided along the first hole 921, and the second flap 952, which is provided along the second hole 922, are stationary before the washing water flows in. As shown in Figure 10, the first hole 921 is closed by the first flap 951, and the second hole 922 is closed by the second flap 952.

[0030] As shown in Figure 11B, for example, if the forward water flow is from right to left in the figure, then washing water flows in through the first hole 921, and the first flap 951 rotates inward. The second flap 952 maintains a closed state of the second hole 922. The incoming washing water flows between the first flap 951 and the partition member 931 and flows out through the mesh portion 924. Lint contained in the washing water is collected by the mesh portion 924.

[0031] In the intermediate state where the water flow is reversed, both the first flap 951 and the second flap 952 rotate due to the water flow, as shown in Figure 11C. The wash water flows from between the second flap 952 and the partition member 931 toward the mesh section 924. Due to the changing water flow, wash water also flows into the housing 91 from the mesh section 924.

[0032] When the water flow reverses, as shown in Figure 11D, the second flap 952 rotates inward due to the wash water flowing in from the second hole 922. The first flap 951 closes the first hole 921. The wash water that flows into the housing 91 flows out through the mesh section 924. Lint contained in the wash water is collected in the mesh section 924. Thus, the collection device 90 is configured to remove lint contained in the wash water that flows in.

[0033] Figure 3 is a cross-sectional view of the collection device 30 provided in the washing machine 1 according to this embodiment, and corresponds to cross-section AA in Figure 2. While the conventional collection device 90 has a partition member 931 integrated with the rear portion 93, the collection device 30 shown in Figure 3 is provided such that the partition member 36 is rotatable relative to the housing 31.

[0034] Referring to Figures 2 and 3, the housing 31 is formed in a hollow box shape by fitting together the main body portion 32 and the rear portion 33. Opposing side walls 321 of the main body portion 32 are provided with a first hole 351 and a second hole 352, respectively.

[0035] The first hole 351 and the second hole 352 are elongated in the longitudinal direction of the main body 32 and are provided in a substantially rectangular notch shape that is open to the outer circumference X2 of the main body 32. The first hole 351 and the second hole 352 form a substantially rectangular opening when the main body 32 is closed by the back surface 33. Multiple mesh portions 34 are provided at equal intervals on the inner circumference X1 surface of the main body 32.

[0036] Inside the housing 31, a first flap 371 is positioned inside the first hole 351, and a second flap 372 is positioned inside the second hole 352. The first flap 371 and the second flap 372 are positioned opposite each other with a partition member 36 in between.

[0037] As shown in Figure 3, the first surface 371a of the first flap 371 covers and closes the first hole 351 from the inside. The first surface 371a extends from the shaft portion 371c toward the outer circumference X2. The second surface 371b of the first flap 371 extends in a direction intersecting the first surface 371a and along the inner surface of the back portion 33.

[0038] The first surface 372a of the second flap 372 covers and closes the second hole 352 from the inside. The first surface 372a extends from the shaft portion 372c toward the outer circumference X2. The second surface 372b of the second flap 372 extends in a direction intersecting the first surface 372a and along the inner surface of the rear portion 33. In the exemplary embodiment, the first flap 371 and the second flap 372 have a cross-sectional shape that is approximately L-shaped or hook-shaped and are arranged in the housing 31 along the vertical direction, the Y direction.

[0039] The partition member 36 is disposed between the first flap 371 and the second flap 372 within the housing 31. In the exemplary embodiment, the partition member 36 is provided along a crossing direction (the Y direction, which is the vertical direction in the exemplary embodiment) that intersects the circumferential direction of the tank 12, and is located between the first flap 371 and the second flap 372. The partition member 36 has a shaft portion 361 extending in the Y direction, and the shaft portion 361 is rotatably supported on the rear portion 33 of the housing 31. The partition member 36 is rotatable either towards the first flap 371 side or towards the second flap 372 side.

[0040] The partition member 36 comprises a plate-shaped base portion 362 extending from the shaft portion 361 and a tip portion 363 connected to the base portion 362 and extending in a direction intersecting the base portion 362. Preferably, the base portion 362 and the tip portion 363 are provided such that their cross-sectional shape, when viewed in the Y direction, is substantially Y-shaped or substantially T-shaped. In the exemplary embodiment, the tip portion 363 of the partition member 36 is provided in a curved shape that is convex toward the rear portion 33 and has a substantially U-shaped cross-sectional shape. The tip portion 363 is provided integrally with the free end side of the base portion 362.

[0041] The first flap 371 and the second flap 372 are arranged symmetrically with respect to the partition member 36. The partition member 36 is also sized so that its tip 363 does not come into contact with the inner wall of the housing 31.

[0042] The first flap 371 is rotatable within the housing 31 around its shaft portion 371c. The rotation radius R1 corresponds to the distance between the shaft portion 371c and the tip of the first flap 371. The second flap 372 is also rotatable with a rotation radius R2 around its shaft portion 372c. The partition member 36 is rotatable within the housing 31 around its shaft portion 361. The rotation radius R3 of the partition member 36 corresponds to the distance between the shaft portion 361 and the tip of its tip portion 363. The distance L13 between the shaft portion 361 of the partition member 36 and the shaft portion 371c of the first flap 371 is as follows: Formula 1:L13 <R1+R3 It is provided to satisfy the following. Furthermore, the distance L23 between the shaft portion 361 of the partition member 36 and the shaft portion 372c of the second flap 372 is as follows: Formula 2:L23 <R2+R3 It is designed to satisfy the following conditions.

[0043] As shown in Figure 3, the tip 363 of the partition member 36 is located on the rotational trajectory of the first flap 371 with a rotational radius R1, and is positioned to be within the rotational range of the first flap 371. Furthermore, the tip 363 of the partition member 36 is located on the rotational trajectory of the second flap 372 with a rotational radius R2, and is positioned to be within the rotational range of the second flap 372.

[0044] Ribs 323 and 324 are provided protruding from the inner surface of the main body 32. One rib 323 is provided on the side of the shaft portion 371c of the first flap 371, and restricts the rotation of the first flap 371 to a predetermined range. The other rib 324 is provided on the side of the shaft portion 372c of the second flap 372, and restricts the rotation of the second flap 372 to a predetermined range. The partition member 36 is provided to rotate between the first flap 371 and the second flap 372 by the washing water flowing into the housing 31.

[0045] Figures 4 to 7 are schematic diagrams illustrating how laundry water flows within the housing 31 of the collection device 30, and show the movements of the first flap 371, the second flap 372, and the partition member 36.

[0046] As shown in Figure 4, for example, suppose the forward water flow is from right to left in the figure, and laundry water flows in through the first hole 351 (see Figure 3). In this case, the first flap 371 rotates inward due to the water flow, opening the first hole 351. The inward rotation of the first flap 371 is restricted by the rib 323. Since the water flow is from right to left in the figure, the second flap 372 does not rotate and closes the second hole 352 (see Figure 3). The partition member 36 rotates towards the second flap 372 in response to the water flow. The incoming laundry water flows between the partition member 36 and the first flap 371 and flows out through the mesh section 34. Lint contained in the laundry water is collected by the mesh section 34.

[0047] In this configuration, compared to the conventional example shown in Figure 11B, the partition member 36 rotates towards the second flap 372 due to the water flow, thus widening the gap between the first flap 371 and the partition member 36. This allows for an increase in the amount of laundry water circulating within the housing 31, thereby enhancing the lint collection effect. Furthermore, since the partition member 36 attempts to hold the second flap 372 in a closed position due to the water flow, the water flowing in from the first hole 351 can be allowed to flow out through the mesh portion 34 without flowing out through the second hole 352.

[0048] In the intermediate state where the water flow is reversed, laundry water flows into the housing 31 from the second hole 352 and the mesh portion 34. As shown in Figure 5, the second flap 372, which had been closing the second hole 352, begins to rotate in response to the water flow, opening the second hole 352. The water flow also acts on the partition member 36, and the base portion 362 begins to rotate toward the first flap 371 in response to the water flow.

[0049] Next, as shown in Figure 6, the water flowing in from the mesh section 34 causes the first flap 371 to begin rotating away from the rib 323. Both the first flap 371 and the second flap 372 are now rotated. The inward rotation of the second flap 372 is restricted by the rib 324. The partition member 36 rotates toward the first flap 371 due to the water flow. The tip 363 of the partition member 36 is positioned within the rotation range of the first flap 371, so the first flap 371 rotates while engaging with the partition member 36, pushing the first flap 371 outward. The first flap 371 rotates toward the first hole 351.

[0050] When the water flow reverses, as shown in Figure 7, the washing water flowing in from the second hole 352 causes the second flap 372 to rotate until it contacts the rib 324. The partition member 36 rotates toward the first flap 371, and the first flap 371 is pushed outward by the partition member 36, closing the first hole 351. The incoming washing water flows between the second flap 372 and the partition member 36 and flows out through the mesh portion 34. Lint contained in the washing water is collected by the mesh portion 34.

[0051] In this configuration, compared to the conventional example shown in Figure 11D, the partition member 36 rotates towards the first flap 371 due to the water flow, thus widening the gap between the second flap 372 and the partition member 36. This makes it possible to increase the amount of laundry water circulating within the housing 31. As a result, the collection device 30 can more effectively remove lint contained in the incoming laundry water, thereby improving the lint collection performance.

[0052] Furthermore, since the partition member 36 attempts to push the first flap 371 back to the closed position with the water flow, the water flow that flows in from the second hole 352 can be allowed to flow out through the mesh section 34 without flowing out through the first hole 351. In this way, the partition member 36 attempts to push the flap located downstream of the water flow back to the closed position, which effectively suppresses the outflow of water flow that flows in from the upstream hole through the downstream hole, thereby improving the lint collection performance of the mesh section 34.

[0053] Furthermore, the partition member 36 is not limited to being composed of a single rotatable member, but may be composed of multiple rotatable partition members 36 arranged along the Y direction. In this case, it is preferable that the multiple partition members 36 extend in the longitudinal direction of the inner surface of the back portion 33 and are rotatably supported by the back portion 33. The shape of the tip portion 363 is not limited to a curved surface, and may be any shape as long as it has a shape that extends in a direction intersecting the base portion 362.

[0054] (Embodiment 2) Figure 8 is a perspective view showing an example of an opening / closing member 39 in a collection device 30 of a washing machine 1 according to Embodiment 2. In this collection device 30, the basic configuration can be the same as in Embodiment 1, and it is characterized by the opening / closing member 39 (first opening / closing member and second opening / closing member) that opens or closes the first hole 351 and the second hole 352.

[0055] The first flap 391 and the second flap 392, which serve as the opening and closing members 39, may be configured to have a plurality of through holes 393, as shown in Figure 8. For example, the first flap 391 has a plurality of through holes 393 on its second surface 39b. The plurality of through holes 393 are arranged at equal intervals along the Y direction (vertical direction). The first surface 39a of the first flap 391 does not have any through holes. The first flap 391 is provided with shafts 394 and 395 at both ends, and these shafts 394 and 395 are rotatably supported by the main body 32 of the housing 31, respectively.

[0056] The second flap 392 also has multiple through holes 393 provided at equal intervals on its second surface 39b, while the first surface 39a does not have any through holes. As described above, the first flap 391 and the second flap 392 are arranged symmetrically with respect to the partition member 36, so it is also possible to use a flap with the same shape as the first flap 391 as the second flap 392 by turning it upside down. For example, by reversing the upper shaft portion 394 of the first flap 391 in the figure to become the lower shaft portion 394 of the second flap 392 in the figure, two opening and closing members 39 with a common configuration can be used as the first flap 391 and the second flap 392.

[0057] When laundry water flows through the housing 31, it can be guided towards the mesh section 34 through the through holes 393 of the first flap 391 and the second flap 392, thereby increasing the amount of water flowing. As a result, the lint collection performance in the laundry water can be improved.

[0058] As described above, in any embodiment of the washing machine 1 of this disclosure, it is possible to improve the lint collection performance of the collection device 30.

[0059] The embodiments disclosed herein are illustrative in all respects and are not intended to be restrictive. Therefore, the technical scope of this disclosure is not construed solely by the embodiments described herein, but is determined by the claims. [Explanation of Symbols]
