The water flowing in from the fourth supply port 54 comes into contact with the inner surface of the second contact plate 572 of the regulating portion 57, flow downward, and is regulated to flow into the second supply portion 602.

[0028] In the first supply section 601, for example, fabric softener is put as the chemical. The water and the chemical supplied through the first supply port 41 and the third supply port 53 are mixed in the first supply section 601 and discharged from the discharge section 611. In the second supply section 602, for example, liquid detergent or powder detergent is put as the chemical. The water and the chemical supplied through the second supply port 42 and the fourth supply port 54 are mixed in the second supply section 602 and discharged from the first opening 631 of the bottom surface 63. The mixed water is discharged from the first supply section 601 or the second supply section 602 to the storage section 4 and supplied toward the tub 11 through the drain port 45 of the storage section 4.

[0029] Fig. 4 is a plan view showing the medicine feed case 5 with the restricting portion 57 removed. Fig. 5 is a right side view of the medicine feed case 5 shown in Fig. 4, and Fig. 6 is a left side view thereof. Fig. 7 is a cross-sectional view taken along line AA in Fig. 4, Fig. 8 is a cross-sectional view taken along line BB in Fig. 5, Fig. 9 is a cross-sectional view taken along line CC in Fig. 2, and Fig. 10 is a cross-sectional view taken along line DD in Fig. 2. In each of Figs. 4 to 6, openings (through holes) penetrating from the inside to the outside are shown in light ink.

[0030] 4, a first supply part 601 and a second supply part 602 are arranged adjacent to each other in medicine feed case 5. A third supply port 53 is provided on the first supply part 601 side, and a fourth supply port 54 is provided on the second supply part 602 side.

[0031] 5, the medicine feed case 5 includes an upper wall 64 including a bottom surface 63 of the second supply section 602, and a lower wall 65 extending downward from the outer surface of the upper wall 64. The lower wall 65 is spaced apart from the first opening 631 of the bottom surface 63 and disposed so as to surround at least a part of the first opening 631. In this embodiment, the lower wall 65 is disposed in a substantially U-shape surrounding the first opening 631 and is open to the first supply section 601 side (the drain outlet 45 side of the storage section 4) (see FIG. 9).

[0032] Returning to FIG. 4, the wall portion 50 constituting the medicine supply case 5 is formed with a through hole connecting the first supply portion 601 to the outside of the medicine supply case 5, and a through hole connecting the second supply portion 602 to the outside of the medicine supply case 5.

[0033] In this embodiment, the wall 50 constituting the medicine injection case 5 includes a first wall 51 in which a third supply port 53 is formed, and a second wall 52 facing the first wall 51. The first supply section 601 is provided with first through holes 71a, 71b, and 71c opening in the first wall 51 and a second through hole 72 opening in the second wall 52 as through holes connecting the first supply section 601 and the outside of the medicine injection case 5. The third through hole 73 opening in the third wall 58 on the second supply section 602 side is provided as a through hole connecting the second supply section 602 and the outside of the medicine injection case 5.

[0034] (First through hole) Three first through holes 71a, 71b, and 71c are formed in the first wall portion 51, penetrating the first wall portion 51 in the up-down direction. The first through holes 71a, 71b, and 71c are located below the third supply port 53, and each of them is formed to open in a substantially rectangular shape. The cross-sectional area of ​​the opening of each of the first through holes 71a, 71b, and 71c is smaller than the cross-sectional area of ​​the opening of the second through hole 72. Among these first through holes 71a, 71b, and 71c, the first through hole 71b formed in the middle has the smallest cross-sectional area of ​​the opening. The shapes and sizes of the first through holes 71a, 71b, and 71c are not limited to the illustrated forms.

[0035] The first wall portion 51 further has three recesses 511, 512, and 513. As shown in FIG. 7, the recesses 511, 512, and 513 are open upward and have a concave shape downward. The first through hole 71a is formed in the recess 511, the first through hole 71b is formed in the recess 512, and the first through hole 71c is formed in the recess 513. The middle first through hole 71b is disposed in the center of the recess 512. The first through hole 71a of the recess 511 is disposed closer to the recess 512. The first through hole 71c of the recess 513 is disposed closer to the recess 512.

[0036] With the restricting portion 57 attached to the medicine feed case 5, water flowing in from the third supply port 53 abuts against the first abutment plate 571 of the restricting portion 57 and is restricted to flow downward, and flows into the first supply portion 601 and into the recesses 511, 512, and 513 of the first wall portion 51. The water that has flowed into the recesses 511, 512, and 513 flows out from the respective first through-holes 71a, 71b, and 71c.

[0037] As shown in FIG. 5, the medicine injection case 5 has a guide portion 74a that guides the water that flows out from the first through holes 71a, 71b, and 71c to the outside of the medicine injection case 5 to the inner surface of the storage section 4. As shown in FIG. 7, the guide portion 74a includes a portion located below the first through holes 71a, 71b, and 71c. The guide portion 74a is also disposed so as to include a portion located below the recesses 511, 512, and 513. The first through holes 71a, 71b, and 71c are open toward the guide portion 74a. The guide portion 74a and the first through holes 71a, 71b, and 71c are disposed opposite to each other.

[0038] The guide portion 74a includes a plate-shaped portion 740 provided at an incline with respect to the up-down direction. The plate-shaped portion 740 is disposed opposite the first through holes 71a, 71b, and 71c. As shown in FIG. 8, the guide portion 74a has a first side wall portion 741 extending upward from one end portion of the plate-shaped portion 740 in the width direction and a second side wall portion 742 extending upward from the other end portion of the plate-shaped portion 740 in the width direction when the portion of the medicine injection case 5 where the guide portion 74a is provided is viewed in plan. The guide portion 74a is provided with a protruding amount that does not abut against the inner surface of the storage portion 4.

[0039] The medicine injection case 5 has two walls 75 protruding outward from the outer surface of the wall 50. The walls 75 are integrally formed on the outer surface of the first wall 51, and extend from the first through holes 71a, 71b, and 71c toward the guide 74a. In this embodiment, the wall 75 is integrally formed on the outer surface of the wall 50 of the medicine injection case 5 and the outer surface of the first wall 51 in which the first through holes 71a, 71b, and 71c are provided. The two walls 75 extend in the up-down direction parallel to each other. As shown in FIG. 7, the wall 75 is disposed so as to divide the areas below the recesses 511, 512, and 513 into three areas.

[0040] 9, the water flowing out from the first through-hole 71b is guided by the guide portion 74a and flows toward the storage unit 4, flows downward through the gap 46 between the side wall 40 of the storage unit 4 and the guide portion 74a, and flows down along the inner surface of the storage unit 4. Similarly, the water flowing out from the first through-holes 71a and 71c is guided to flow along the inner surface of the storage unit 4. As the water flows into the storage unit 4 in this manner, the inner surface of the storage unit 4 is washed away.

[0041] The opening of the central first through-hole 71b, where the water flow is likely to concentrate, is smaller than the opening of the first through-holes 71a and 71c on either side. This reduces the flow rate of water from the first through-hole 71b, allowing the water to flow out appropriately from each of the three first through-holes 71a, 71b, and 71c.

[0042] As shown in FIG. 7, the water flowing out of the first through holes 71a, 71b, 71c is guided by the wall portion 75 and flows downward, and reaches the plate-shaped portion 740 of the guide portion 74a. Since the area below the first through holes 71a, 71b, 71c is divided into three by the wall portion 75, the water flows evenly through the plate-shaped portion 740 of the guide portion 74a. The water also reaches one side end and the other side end in the width direction of the plate-shaped portion 740. Since the guide portion 74a is provided with the first side wall portion 741 and the second side wall portion 742, the water is prevented from flowing down from both ends in the width direction of the plate-shaped portion 740, and is collected on the guide portion 74a.

[0043] This allows water to flow uniformly from the entire width of guide portion 74a to the inner surface of storage portion 4. Guide portion 74a is provided wide in the width direction in the region below recesses 511, 512, and 513 having first through holes 71a, 71b, and 71c, so that a wide area for water to flow into storage portion 4 can be secured. Therefore, the area that can be washed out of storage portion 4 can be increased. Even if a medicine or mixed water is attached to storage portion 4, it can be washed out by water flowing from guide portion 74a, making it possible to prevent the occurrence of dirt.

[0044] (Second through hole) 6, the second through hole 72 of the medicine feed case 5 is provided in the second wall portion 52. The second through hole 72 connects the first supply portion 601 and the outside of the second wall portion 52. In a side view, the second through hole 72 is formed in a substantially rectangular shape and opens wider in the width direction than in the vertical direction.

[0045] As shown in FIG. 4, the second through hole 72 is formed in the second wall portion 52 facing the first wall portion 51 in which the third supply port 53 is provided, and is provided at a position farther from the third supply port 53 than the first through holes 71a, 71b, and 71c. The first through holes 71a, 71b, and 71c located closer to the third supply port 53 have a higher water pressure, so that a certain flow rate can be ensured. As described above, the cross-sectional area of ​​the second through hole 72 is larger than the cross-sectional area of ​​the first through holes 71a, 71b, and 71c. Therefore, even in the second through hole 72 located farther from the third supply port 53, a certain flow rate can be ensured.

[0046] The drug supply case 5 has a guide portion 74b that guides the water that has flowed out of the drug supply case 5 from the second through-hole 72 to the inner surface of the storage section 4. As shown in Fig. 6, the guide portion 74b includes a portion located below the second through-hole 72 and is provided wider in the width direction than the opening width X of the second through-hole 72.

[0047] The guide portion 74b is provided with a protruding amount that does not contact the inner surface of the storage portion 4. The guide portion 74b is provided on the outer surface of the second wall portion 52, and includes a plate-shaped portion 740 provided at an angle with respect to the up-down direction. The plate-shaped portion 740 protrudes in a direction intersecting with the second wall portion 52. The guide portion 74b also has a first side wall portion 741 extending upward from one end portion of the plate-shaped portion 740 in the width direction, and a second side wall portion 742 extending upward from the other end portion of the plate-shaped portion 740 in the width direction.

[0048] In this embodiment, the guide portion 74b is provided at a position in the width direction such that one side end of the plate-shaped portion 740 is closer to the second through hole 72 than the other side end. The first side wall portion 741 is disposed close to one side end of the second through hole 72, and the second side wall portion 742 is disposed away from the other side end of the second through hole 72. The upper end of the first side wall portion 741 is formed to be located higher than the upper end of the second side wall portion 742.

[0049] When the restricting portion 57 is attached to the medicine feeding case 5, the water flowing in from the third supply port 53 abuts against the first abutment plate 571 of the restricting portion 57 and flows downward, flows into the first supply portion 601, and reaches the second through hole 72. As shown in Fig. 9, the water flowing out from the second through hole 72 is guided by the guide portion 74b and flows toward the storage portion 4, flows downward through the gap 46, and flows down along the inner surface of the storage portion 4. The water flowing along the inner surface of the storage portion 4 can clean the storage portion 4.

[0050] The first side wall portion 741, which is close to the second through hole 72 and has an upper end located upward, has a function of blocking water flowing out from the second through hole 72. The first side wall portion 741 guides water toward the second side wall portion 742 side. By providing the first side wall portion 741, water can be made to flow more uniformly from the entire width direction of the guide portion 74b to the inner surface of the storage portion 4. Since the guide portion 74b is provided widely in the region below the second through hole 72, a wide flow area of ​​water flowing into the storage portion 4 can be secured, and the area of ​​the storage portion 4 to be washed can be made large. Even on the guide portion 74b side, medicines and the like attached to the storage portion 4 can be washed away with water from the second through hole 72, making it possible to prevent the occurrence of dirt.

[0051] (Third through hole) 4, in the second supply section 602 of the medicine injection case 5, the wall section 50 includes a third wall section 58 in which a fourth supply port 54 is formed. The second supply section 602 is provided with a third through hole 73 as a through hole connecting the outside of the medicine injection case 5 and the second supply section 602. The third through hole 73 is provided in the third wall section 58 and is formed penetrating in the up-down direction.

[0052] The medicine supply case 5 has a guide portion 74c that guides the water that has flowed out of the medicine supply case 5 from the third through hole 73 to the inner surface side of the storage unit 4. As shown in FIG. 7, the guide portion 74c includes a portion located below the third through hole 73. The third through hole 73 opens toward the guide portion 74c. The guide portion 74c is provided with a protruding amount that does not abut against the inner surface of the storage unit 4.

[0053] 5, the guide portion 74c includes a plate-shaped portion 740 that is provided at an angle with respect to the up-down direction. The plate-shaped portion 740 is disposed opposite the third through-hole 73. Like the guide portion 74a, the guide portion 74c also has a first side wall portion 741 that extends upward from one end portion of the plate-shaped portion 740 in the width direction, and a second side wall portion 742 that extends upward from the other end portion of the plate-shaped portion 740 in the width direction.

[0054] When the restricting portion 57 is attached to the medicine feeding case 5, the water flowing in from the fourth supply port 54 abuts against the second abutment plate 572 of the restricting portion 57 and flows downward, into the second supply portion 602, and also into the third through hole 73. As shown in FIG. 10, the water flowing out from the third through hole 73 is guided by the guide portion 74c, flows downward through the gap 46 between the guide portion 74c and the side wall 40, and flows down along the inner surface of the storage portion 4. Since the guide portion 74c is also provided with the first side wall portion 741 and the second side wall portion 742, the water is prevented from flowing down from both ends in the width direction of the plate-shaped portion 740, and is collected on the guide portion 74c.

[0055] 7, water can be made to flow uniformly from the entire width of guide portion 74c to the inner surface of storage portion 4. Guide portion 74c is provided wide in the width direction in the region below third through-hole 73, so that a wide area for water to flow into storage portion 4 can be secured. Therefore, the area of ​​storage portion 4 to be washed can be made wide.

[0056] In the washing machine 1, the chemical feed case 5 is provided with guide parts 74a, 74b, and 74b (hereinafter, the "guide parts 74a, 74b, and 74b" may be collectively referred to as "guide part 74") that guide the water that has flowed out of the chemical feed case 5 from the through hole to the inner surface of the storage part 4. This allows the inner surface of the storage part 4 to be effectively cleaned. This can prevent chemicals such as detergent from remaining in the storage part 4. Specifically, the guide part 74 can direct the flow direction of the water that has flowed out of the chemical feed case 5 to the inner surface of the storage part 4, so that a strong water flow can be supplied to the inner surface of the storage part 4. As a result, the inner surface of the storage part 4 can be effectively cleaned.

[0057] The shape and position of the guide portion 74 are not particularly limited as long as the water flowing out of the medicine injection case 5 is guided by the guide portion 74 to the inner surface side of the storage portion 4. For example, the guide portion 74 preferably includes a portion located below the through-hole. In this case, the water flowing out of the through-hole falls and is further accelerated, and is guided by the guide portion 74 to the inner surface side of the storage portion 4, so that a stronger water flow can be supplied to the inner surface of the storage portion 4. This can further improve the cleaning effect.

[0058] From the viewpoint of supplying water to a wider range of the inner surface of the storage section 4, it is preferable that the guide section 74 has a plate-shaped section. When the guide section 74 has a plate-shaped section, it is preferable that the plate-shaped section extends from one side of one end of the through hole to the other side of the other end in the width direction when viewed from the extending direction of the through hole. It is preferable that the plate-shaped section is provided over a wider area in the width direction, including the area where the through hole is provided.

[0059] Furthermore, it is preferable that the guide portion 74 includes a plate-shaped portion inclined in the vertical direction. The inclined plate-shaped portion can control the area to which water is supplied on the inner surface of the storage portion 4. For example, by providing an inclined plate-shaped portion on at least one of both ends in the width direction of the plate-shaped portion, it is possible to suppress water from flowing down from the plate-shaped portion toward the outside in the width direction. As a result, water can be efficiently flowed toward the inner surface side of the storage portion 4. From this viewpoint, it is preferable that a plurality of inclined plate-shaped portions are provided, and the plurality of inclined plate-shaped portions (side wall portions) are provided at different positions from each other in the width direction. For example, it is preferable that the guide portion 74 is in the shape of a gutter extending toward the inner surface side of the storage portion 4. When the guide portion 74 is in the shape of a gutter, water can be temporarily stored in the guide portion, and the water flow can be strengthened. For example, the gutter-shaped guide portion 74 preferably has at least one of a first side wall portion extending upward from one end of the horizontally extending plate-like portion and a second side wall portion extending upward from the other end of the plate-like portion, and more preferably has both the first side wall portion and the second side wall portion. In this case, if the distance in the width direction between the first side wall portion and the through hole is shorter than the distance in the width direction between the second side wall portion and the through hole, it is preferable that the dimension in the height direction of the first side wall portion is larger than the dimension in the height direction of the second side wall portion. With this configuration, water can be effectively supplied to a position away from the through hole.

[0060] It is preferable that the medicine injection case 5 has a wall extending from the through hole side toward the guide part 74 side. By providing this wall, it is possible to supply water uniformly to the entire guide part. Also, the amount of water supplied to the guide part can be controlled at each point.

[0061] For example, assume that the medicine injection case 5 has three or more through holes formed at different positions in the width direction. The three or more through holes include three through holes, a central through hole located at the center, a one-side through hole located on one side in the width direction with respect to the central through hole, and an other-side through hole located on the other side in the width direction with respect to the central through hole. In that case, it is preferable to include a first wall portion located between the one-side through hole and the central through hole in the width direction, and a second wall portion located between the other-side through hole and the central through hole. Each of the first wall portion and the second wall portion is preferably spaced apart from the guide portion 74. In this case, the first and second wall portions prevent water from the one-side through hole and the other-side through hole from flowing into the central region where the central through hole is provided, where water from the three through holes is most likely to collect, and water is suitably supplied to both sides of the region. Therefore, water can be supplied to a wide area with higher uniformity.

[0062] In the medicine injection case 5 provided in the medicine injection section 2, the action of these multiple guide parts 74a, 74b, 74c allows water to flow on the inner surface of the storage section 4. Even if medicine or the like adheres to the inner surface of the storage section 4, it can be washed away with water guided by the guide parts 74a, 74b, 74b, making it possible to prevent the occurrence of dirt. In addition, water can be distributed over a wide area of ​​the inner surface of the storage section 4, and by flowing sufficient water over the entire surface, it is possible to prevent medicine from remaining locally accumulated.

[0063] In the present embodiment, the guide portion that guides the water flowing out of the medicine supply case from the first to third through holes to the inner surface of the storage portion has a plate-shaped portion, a first side wall portion, and a second side wall portion, but the guide portion in the washing machine disclosed herein is not limited to such a shape. The guide portion may have any shape, for example, a plate-shaped portion in the vertical direction or a pin shape, as long as it includes a portion located below the through hole. In addition, the size, shape, number, etc. of the through hole provided in the wall portion are not limited as long as it is an opening that connects the supply portion and the outside of the medicine supply case.

[0064] The embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present disclosure should not be interpreted solely by the above-described embodiments, but should be determined based on the claims. [Explanation of symbols]
