[0013] Figure 2 It is a perspective view showing the storage section 4 and the medicine insertion cassette 5 included in the medicine insertion section 2 . Figure 3 It is an exploded perspective view of the storage unit 4 and the medicine cassette 5 .

[0014] The washing machine body 10 includes a storage portion 4 and a medicine insertion box 5 as a medicine insertion portion 2 on the inner side of the washing machine body 10. An internal space for accommodating the medicine insertion box 5 is formed in the storage portion 4. In this embodiment, Figure 3 As shown, the housing portion 4 is a recessed portion that opens upward.

[0015] The storage part 4 is a generally rectangular shape that is long in the front-rear direction of the washing machine body 10 when viewed from above, and is formed into a polygonal shape. The polygon includes a polygon whose corners are chamfered or rounded. In addition, the polygon also includes a polygon whose at least one side is composed of a curve. In addition, the rectangle includes not only a rectangle but also a square.

[0016] The receiving portion 4 has an inclined surface at the bottom and is provided with a water flow slope. A drain port 45 is opened at the bottom of the receiving portion 4 on the underwater side. The side wall 40 of the receiving portion 4 is provided with an opening for connecting a water supply pipe, namely a first supply port 41 and a second supply port 42. The first supply port 41 and the second supply port 42 are both arranged in a circular shape and are formed at intervals from each other.

[0017] A flange 43 protruding outward is provided at the upper edge of the receiving portion 4. The flange 43 is used to fix the receiving portion 4 to the washing machine body 10 and has a plurality of screw holes. A step portion 44 extending in the horizontal direction is provided at the inner periphery of the flange 43 at a position lower than the flange 43.

[0018] like Figure 3 As shown, the medicine input box 5 is formed to be able to be stored in the storage section 4. A flange 55 protruding outward is provided on the upper edge of the medicine input box 5. The flange 55 is formed in a flange shape extending outward. The flange 55 is arranged above the step portion 44 of the storage section 4. The flange 55 is not limited to a flange shape, and can be formed in any shape as long as it is a shape protruding outward of the medicine input box 5.

[0019] The medicine box 5 has a wall 50 connected to the flange 55. The medicine box 5 has a supply unit 6 for supplying medicine. When the medicine box 5 is stored inside the storage unit 4, the wall 50 is located between the supply unit 6 of the medicine box 5 and the inner surface of the storage unit 4.

[0020] The wall portion 50 is provided with a third supply port 53 and a fourth supply port 54. The third supply port 53 and the fourth supply port 54 penetrate the wall portion 50 in the thickness direction. The top view shape of the third supply port 53 is a circle with the same diameter as the first supply port 41. The top view shape of the fourth supply port 54 is a circle with the same diameter as the second supply port 42. In the present embodiment, the fourth supply port 54 is an opening with a larger diameter than the third supply port 53.

[0021] The third supply port 53 and the fourth supply port 54 are provided at positions corresponding to the first supply port 41 and the second supply port 42 of the storage section 4. When the storage section 4 stores the medicine input box 5, the first supply port 41 is aligned with the third supply port 53, and the second supply port 42 is aligned with the fourth supply port 54, and water from the respectively connected water supply pipes can flow.

[0022] A part of the wall portion 50 of the medicine insertion box 5 is provided with a detachable restricting portion 57. The restricting portion 57 is arranged from the upper edge of the medicine insertion box 5 to the inner side of the wall portion 50 where the third supply port 53 and the fourth supply port 54 are provided.

[0023] The limiting portion 57 includes a first abutment plate 571 opposite to the third supply port 53 and a second abutment plate 572 opposite to the fourth supply port 54. The first abutment plate 571 and the second abutment plate 572 are formed to bulge toward the inner side of the supply portion 6 and are formed as plate-shaped portions extending obliquely downward. By installing the limiting portion 57 on the wall portion 50 of the medicine input box 5, the third supply port 53 and the fourth supply port 54 are covered by the limiting portion 57.

[0024] When the limiting portion 57 is installed on the medicine input box 5, a gap is formed between the first abutting plate 571 and the wall portion 50, and the gap is open downward. In addition, a gap is formed between the second abutting plate 572 and the wall portion 50, and the gap is open downward. The second abutting plate 572 is provided with a notch 573 on the side opposite to the first abutting plate 571. By providing the notch 573 on the limiting portion 57, the second abutting plate 572 and the wall portion 50 are also open to the side of the fourth supply port 54. The side of the second abutting plate 572 is not in contact with the wall portion 50 and is separated.

[0025] like Figure 2 As shown, the medicine input box 5 includes a first supply part 601 and a second supply part 602 as the supply part 6. The first supply part 601 and the second supply part 602 are divided by an inner wall 56 extending in the up-down direction and are separated from each other. The first supply part 601 and the second supply part 602 are both formed in a shape that is open at the top and concave at the bottom. The first supply part 601 and the second supply part 602 can be, for example, cylindrical, oblong cylindrical or elliptical cylindrical.

[0026] The bottom surface 611 of the first supply part 601 is provided with a discharge part 612 for discharging water in the first supply part 601 toward the storage part 4. The discharge part 612 may also be covered by an appropriate cover. The bottom surface 64 of the second supply part 602 is provided with a first through hole 65.

[0027] The first abutment plate 571 of the restriction portion 57 is provided corresponding to the first supply portion 601, and the second abutment plate 572 is provided corresponding to the second supply portion 602. Through the restriction portion 57, water flowing in from the third supply port 53 abuts against the inner surface of the first abutment plate 571 of the restriction portion 57 and changes its flow downward, and is restricted to flow into the first supply portion 601. In addition, water flowing in from the fourth supply port 54 abuts against the inner surface of the second abutment plate 572 of the restriction portion 57 and flows downward, and also flows to the side of the fourth supply port 54 through the notch 573, and is restricted to flow into the second supply portion 602.

[0028] As a chemical, for example, softener is put into the first supply part 601. Water and the chemical supplied through the first supply port 41 and the third supply port 53 are mixed in the first supply part 601 and discharged from the discharge part 612. As a chemical, for example, liquid detergent or powder detergent is put into the second supply part 602. Water and the chemical supplied through the second supply port 42 and the fourth supply port 54 are mixed in the second supply part 602 and discharged from the first through hole 65. The mixed water is discharged from the first supply part 601 or the second supply part 602 to the storage part 4, and is supplied to the tank 11 through the drain port 45 of the storage part 4.

[0029] Figure 4 2 is a plan view showing the medicine insertion box 5. Figure 4 , the flow of water in the second supply part 602 is summarized. Water from the water supply part 13 is supplied to the second supply part 602 through the fourth supply port 54. As described above, the water flowing in from the fourth supply port 54 abuts against the inner surface of the second abutment plate 572 and flows downward, and at the same time, the water flows into the second supply part 602 from the side of the fourth supply port 54 through the notch 573. The supplied water flows in the circumferential direction along the inner peripheral surface of the second supply part 602. The details will be described later.

[0030] Figure 5 It is a plan view showing the medicine insertion cassette 5 with the restriction portion 57 removed. Figures 6 to 9 yes Figure 4 The cross-sectional view of the medicine dispensing box 5 shown in FIG. Figure 6 It is the AA section view. Figure 7 This is the BB cross-sectional view. Figure 8 It is the CC section view. Fig. 9 is the DD section view. Figure 4 , Figure 5 and the following Fig.10 In the figure, the openings (through holes) that pass through the inside and outside are indicated by light ink color.

[0031] like Figure 5 As shown, an opening 67 connected to the first supply part 601 or the second supply part 602 and the outside of the medicine input box 5 is formed on the wall portion 50 of the medicine input box 5. In the medicine input box 5 of the present embodiment, a plurality of openings 67 are provided on the wall portion 50. In the first supply part 601, a plurality of openings 67 are provided in an area below the third supply port 53. In addition, an opening 67 is also provided on the surface opposite to the third supply port 53. In the second supply part 602, an opening 67 is provided in an area below the fourth supply port 54. The water supplied to the medicine input box 5 is configured to flow to the outside of the medicine input box 5 through these plurality of openings 67.

[0032] The structure of the second supply unit 602 provided in the medicine input box 5 will be described in more detail. Figure 6 As shown, the medicine box 5 has a peripheral surface 60 constituting a second supply portion 602 and a bottom surface 64. The bottom surface 64 is formed with a first through hole 65 connecting the second supply portion 602 and the outside of the medicine box 5.

[0033] The peripheral surface 60 includes a first peripheral surface 61 located in a region where the fourth supply port 54 (hereinafter referred to as the supply port 54) is formed in the height direction X, and a second peripheral surface 62 located below the first peripheral surface 61. In addition, the peripheral surface 60 of the second supply portion 602 has a connecting surface (631, 632) connecting the first peripheral surface 61 and the second peripheral surface 62.

[0034] like Figure 5 As shown, in a plan view, the first connecting surface 631, which is one of the connecting surfaces constituting the peripheral surface 60, extends circumferentially from one side in the width direction (horizontal direction) of the center of the supply port 54. The first connecting surface 631 is formed so that the angle formed by the horizontal direction orthogonal to the height direction X is smaller than that of the first peripheral surface 61.

[0035] The second connection surface 632 of the peripheral surface 60 extends from the other side of the center of the supply port 54 in the width direction. The angle between the second connection surface 632 and the horizontal direction orthogonal to the height direction X is smaller than that of the first peripheral surface 61 .

[0036] The length of the second connection surface 632 along the circumferential direction is different from that of the first connection surface 631. In the medicine cassette 5 of this embodiment, the second connection surface 632 is formed shorter along the circumferential direction than the first connection surface 631. The first connection surface 631 is formed longer than the second connection surface 632 along the circumferential direction.

[0037] In a plan view, the first connection surface 631 is provided with the end on the supply port 54 side as the starting end and the end on the opposite side of the supply port 54 side as the terminal end. The first connection surface 631 is provided with a starting end below the supply port 54, extends in an arc shape along the peripheral surface 60, and is provided with a terminal position near the bottom of one end of the inner wall 56. The first connection surface 631 is extended in the second supply portion 602 to a position farthest from the supply port 54 and diagonally opposite to the supply port 54. The width of the first connection surface 631 is formed to be the widest on the supply port 54 side and gradually narrows.

[0038] In a plan view, the second connection surface 632 starts at the end on the supply port 54 side and ends at the end on the opposite side of the supply port 54 side. Figure 6 As shown, the starting end of the second connection surface 632 is spaced apart from the starting end of the first connection surface 631. In addition, the starting end of the second connection surface 632 is located below the second abutment plate 572 of the limiting portion 57.

[0039] like Figure 5 As shown, the second connection surface 632 extends along the peripheral surface 60 and is formed to terminate near the lower side of one end of the inner wall 56. The second connection surface 632 is also extended to a position farthest from the supply port 54 and diagonally opposite to the supply port 54. The length of the second connection surface 632 in the circumferential direction is shorter than that of the first connection surface 631. The width of the second connection surface 632 is formed to be the widest on the supply port 54 side and gradually narrows.

[0040] In a plan view, the width of the end of the first connection surface 631 on the supply port 54 side (the width on the starting end side) is set to be wider than the width of the end of the second connection surface 632 on the supply port 54 side (the width on the starting end side). The shape that is curved in the circumferential direction of the first connection surface 631 and the second connection surface 632 can be understood as a continuation of a roughly arc-shaped plane that includes a portion of the circumference of a virtual circle centered on a point on the axis along the height direction X of the supply portion 6. The first connection surface 631 is formed so that the average radius of curvature of the virtual circle constituting the first connection surface 631 is smaller than the average radius of curvature of the virtual circle constituting the second connection surface 632. The first connection surface 631 is set to have a greater degree of curvature when viewed from above than the second connection surface 632.

[0041] like Figure 6 As shown, the starting end of the first connecting surface 631 and the starting end of the second connecting surface 632 are also separated in the height direction X and are arranged at different height positions. Figure 7 As shown, the end of the first connection surface 631 and the end of the second connection surface 632 are arranged at different positions and separated in the height direction X. The end of the first connection surface 631 and the end of the second connection surface 632 are arranged not to overlap in the height direction X. In this embodiment, the end of the first connection surface 631 is arranged above the end of the second connection surface 632.

[0042] The first connection surface 631 is an inclined surface having a gentler inclination along the circumferential direction than the second connection surface 632. The first connection surface 631 is formed to have a smaller average inclination angle relative to the horizontal direction than the second connection surface 632. The second connection surface 632 is an inclined surface having a steeper inclination along the circumferential direction than the first connection surface 631.

[0043] The second supply part 602 having such a first connection surface 631 and a second connection surface 632 is configured so that water flowing in from the supply port 54 not only flows downward along the second peripheral surface 62 but also flows in the circumferential direction along the first connection surface 631 and the second connection surface 632. In this case, the water can flow in not only one circumferential direction in the second supply part 602 but also in multiple circumferential directions.

[0044] like Figure 6As shown, the second contact plate 572 of the limiting portion 57 disposed opposite to the supply port 54 has a rib 574 on the inner surface. The rib 574 protrudes from the second contact plate 572 in the direction of the supply port 54. When the limiting portion 57 is mounted on the medicine injection housing 5, the rib 574 is disposed opposite to the supply port 54 and is disposed in a manner of being inclined downward in the direction of the first connecting surface 631 from the other side in the width direction of the center of the supply port 54.

[0045] The water flowing in from the supply port 54 abuts against the inner surface of the second abutment plate 572, changes its flow downward, and falls into the first connection surface 631 and the second connection surface 632. The water flows in the circumferential direction along the first connection surface 631 and the second connection surface 632. The water from the supply port 54 also abuts against the rib 574, and also flows into the first connection surface 631 from the supply port 54. Not only from below the second abutment plate 572, but also from the gap between the notch 573 provided on the side of the second abutment plate 572 and the first circumferential surface 61, water flows in. More water flows into the side of the first connection surface 631 provided near the supply port 54 than into the side of the second connection surface 632. The width of the starting end side of the first connection surface 631 is provided wider, so that more water can flow.

[0046] Reference Figure 4 , the water flowing in the first connection surface 631 flows in an arc shape along the circumferential direction on the first connection surface 631. In the first connection surface 631 where more water flows, the centrifugal force acts on the water flowing in the arc shape. Figure 8 As shown in FIG. 1 , water subjected to centrifugal force has difficulty flowing down from the first connection surface 631 as a gentle slope to the second peripheral surface 62, while rotating and flowing along the circumferential direction on the first connection surface 631. Fig. 9 As shown, the water flows to the end of the first connecting surface 631 and flows downward.

[0047] like Figure 7 As shown, the water flowing in the second connection surface 632 flows along the circumferential direction over a steeper and shorter distance than the first connection surface 631. The water flows to the end of the second connection surface 632 and flows downward.

[0048] The water flowing in the first connection surface 631 and the water flowing in the second connection surface 632 are also guided to flow to their respective ends. Fig. 9 As shown, the water flowing through the first connection surface 631 and the water flowing through the second connection surface 632 leave the supply port 54, reach a position diagonal to the supply port 54, and flow down. The water from the supply port 54 reaches a position diagonal to the supply port 54.

[0049] Thus, water can flow to a portion that is far away from the supply port 54 and to which water is difficult to flow. The end of the first connection surface 631 and the end of the second connection surface 632 are set not to overlap in the height direction X, so that water does not flow too much to one place. The water flowing through the first connection surface 631 and the second connection surface 632 flows downward while cleaning the inner surface of the second supply part 602 and is discharged from the first through hole 65. Even if the medicine or mixed water adheres to the second supply part 602, it can be rinsed with the water flowing through the first connection surface 631 and the second connection surface 632. Although dirt is easily generated at a position far away from the supply port 54, since it is a position where the water flowing through the first connection surface 631 and the water flowing through the second connection surface 632 will flow down, it is possible to prevent the generation of dirt and keep it clean.

[0050] In addition, the connection surface connecting the first circumferential surface 61 and the second circumferential surface 62 is not limited to the configuration shown in the example. The medicine input box 5 may be provided with one of the first connection surface 631 and the second connection surface 632 so that water flows in one circumferential direction, and the water flow may be in a vortex shape. The connection surface is provided not only on the second supply unit 602, but also on the first supply unit 601.

[0051] The medicine insertion box 5 of the present embodiment is configured to prevent not only the inner surface of the supply portion 6 into which the medicine is inserted but also the outer surface from being contaminated.

[0052] like Figure 6 As shown, the second supply portion 602 has an upper wall 71 constituting a bottom surface 64 and a second peripheral surface 62, and a lower wall 72 extending downward from the outer surface of the upper wall 71. The lower wall 72 is provided separately from the first through hole 65, and is provided in a manner of surrounding at least a portion of the first through hole 65. In the present embodiment, the lower wall 72 is surrounded by more than half of the outer periphery of the first through hole 65, and is open to the first supply portion 601 side (the drain port 45 side of the storage portion 4).

[0053] Fig.10 1 is a bottom view of the medicine insertion box 5. As shown in the figure, the lower wall 72 is provided outside a portion of the first through hole 65 and is provided not to be located outside the peripheral surface 60 when viewed from above. The lower wall 72 is provided in a substantially U-shape surrounding the first through hole 65.

[0054] As described above, the medicine box 5 has a first through hole 65 formed on the bottom surface 64 of the second supply portion 602, and the first through hole 65 is opened in a manner connecting the second supply portion 602 and the outer side of the medicine box 5. Figure 5 and Fig.10 As shown, the second supply portion 602 is further provided with a second through hole 66 on the basis of the first through hole 65 .

[0055] The second through hole 66 is provided in the upper wall 71. The second through hole 66 is an opening connecting the second supply portion 602 and the outer side of the medicine input box 5. The second through hole 66 is located in the inner area of ​​the lower wall 72 adjacent to the surface of the lower wall 72 on the side of the first through hole 65, and is formed in plurality along the edge of the first through hole 65 when viewed from above. These plurality of second through holes 66 are arranged in the circumferential direction at intervals from each other.

[0056] In this embodiment, six second through holes 66 are formed on the second supply portion 602. One second through hole 66 is set to be an elongated slit shape in a plan view, and has a rectangular or arc shape. The opening area of ​​the first through hole 65 is larger than the opening area of ​​the second through hole 66, and is opened in a circular shape.

[0057] The plurality of second through holes 66 are arranged so that the ratio of the area where the second through holes 66 are provided in the circumferential direction of the end edge of the first through hole 65 is lower in the area where the bottom wall 72 is not provided than in the area where the bottom wall 72 is provided. Fig.10 In the illustrated example, the plurality of second through holes 66 are located in a region where the lower wall 72 is provided, and there are no second through holes 66 in a region where the lower wall 72 is not provided.

[0058] The upper wall 71 of the second supply part 602 is formed such that the inclination angle with respect to the height direction X is larger in the connection part 73 which is the connection part connected to the lower wall 72 than the upper part located above the connection part 73 of the upper wall 71. In the upper wall 71, the inclination angle with respect to the height direction X is formed such that the inclination angle is smaller in the upper part. In contrast, in the connection part 73, the inclination angle with respect to the height direction X is large, and the connection part 73 is formed into a curved surface shape connected to the bottom surface 64. A plurality of second through holes 66 are provided along the inner side of the connection part 73.

[0059] In the second supply part 602, water supplied through the supply port 54 is mixed with the medicine and discharged from the first through hole 65. In the state where the medicine insertion box 5 is accommodated in the storage part 4, the lower wall 72 is arranged on the inner side of the storage part 4. On the outer side of the second supply part 602, the area below the first through hole 65 and the inner surface of the storage part 4 are divided by the lower wall 72. By providing the lower wall 72, it is possible to suppress the water discharged from the first through hole 65 from splashing onto the inner surface of the storage part 4.

[0060] like Figure 8As shown, in the area below the first through hole 65 divided by the lower wall 72, water is drained not only from the first through hole 65 but also from the plurality of second through holes 66. The water discharged from the second through holes 66 flows along the inner surface 721 of the lower wall 72 and also flows along the back side of the bottom surface 64 of the second supply part 602. The second through hole 66 is provided along the inner side of the connection part 73 connected to the lower wall 72, and a large inclination angle is formed in the connection part 73, so that the water from the second through hole 66 easily flows along the inner surface 721 of the lower wall 72 and extends to the back side of the bottom surface 64. Thus, in the area below the first through hole 65, the outer side of the second supply part 602 and the inner surface of the lower wall 72 can be washed, and the generation of stains can be prevented.

[0061] In addition, in the medicine input box 5, the second through hole 66 can also be provided in the area where the lower wall 72 is not provided, and the illustrated method is not limited. The size, shape, number, etc. of the second through hole 66 are also not limited, and as long as it is an opening located in the area adjacent to the first through hole 65, it can be formed arbitrarily.

[0062] In the washing machine 1, the medicine insertion box 5 is configured so that the water supplied from the supply port 54 flows in the circumferential direction along the inner surface of the supply portion 6. Therefore, the water flow can be effectively supplied to a wide area of ​​the circumferential surface of the supply portion 6 where the medicine is supplied. Therefore, it is difficult for the medicine to remain in the supply portion 6, and the supply portion 6 can be kept clean.

[0063] From the viewpoint of setting the area for supplying water flow as a wider area, it is preferred to connect the first circumferential surface 61 and the second circumferential surface 62, and to provide a connecting surface 63 (the connecting surface 63 is a general term for connecting surfaces including the first connecting surface 631 and the second connecting surface 632) whose angle with the horizontal direction is smaller than that of the first circumferential surface 61. According to this configuration, it is possible to suppress the water flow flowing on the connecting surface 63 from falling downward through the connecting surface 63. Therefore, the area for supplying water flow can be changed to a wider area. In this way, the connecting surface 63 is a surface having the function of guiding water flow, and therefore can also be called a guiding surface.

[0064] The connection surface 63 may be composed of a single connection surface or may include a plurality of connection surfaces. For example, the connection surface 63 may include a first connection surface 631 and a second connection surface 632, and the circumferential length of the second connection surface 632 is different from the circumferential length of the first connection surface 631. For example, depending on the positional relationship with the supply port 6, there is a situation where the amount of water supplied to the first connection surface 631 and the second connection surface 632 is different. By shortening the circumferential length of the connection surface of the first connection surface 631 and the second connection surface 632 to which a smaller amount of water is supplied, and extending the circumferential length of the connection surface to which a larger amount of water is supplied, the water flow can be supplied more evenly. However, the ratio of the length of the first connection surface 631 to the length of the second connection surface 632 is, for example, preferably greater than 0.1 and less than 0.9, more preferably greater than 0.2 and less than 0.8, and further preferably greater than 0.3 and less than 0.7.

[0065] Preferably, the side with a relatively shorter length along the circumferential direction has a larger average inclination angle relative to the horizontal direction in the first connection surface 631 and the second connection surface 632. By shortening the length along the circumferential direction, the average inclination angle of the inclined surface is increased with less water supplied, thereby increasing the flow rate of the water flow. Therefore, cleaning can be effectively performed even on the inclined surface side with less water supplied.

[0066] Preferably, in the first connection surface 631 and the second connection surface 632, the width of the end portion of the connection surface with a longer length along the circumferential direction on the supply port 6 side is wider than the width of the end portion of the connection surface with a shorter length along the circumferential direction on the supply port 6 side. This is because it is easier to supply more water to the front end side on the connection surface with a longer length along the circumferential direction.

[0067] It is preferred that the end (front end) of the first connection surface 631 on the opposite side of the supply port 6 and the end (front end) of the second connection surface 632 on the opposite side of the supply port 6 do not overlap in the height direction. In other words, it is preferred that the front end of the first connection surface 631 and the front end of the second connection surface 632 are separated in the circumferential direction. For example, it is preferred that there is an area in the circumferential direction where neither the first connection surface 631 nor the second connection surface 632 is provided. In this case, for example, it is possible to effectively suppress the water flow on the first connection surface 631 and the water flow on the second connection surface 632 from being concentrated in one place, and water flow cannot be properly supplied to other parts. As a result, water can be more properly supplied to the entire circumferential surface.

[0068] Preferably, the end (front end) of the first connection surface 631 on the opposite side of the supply port 6 and the end (front end) of the second connection surface 632 on the opposite side of the supply port 6 are located at different positions in the height direction. According to this configuration, for example, it is possible to suppress the water flow flowing on the first connection surface 631 from colliding with the water flow flowing on the second connection surface 632 from the front and generating an area where the flow velocity of the water flow is reduced. It is possible to supply a high-flow velocity water flow to a wider area.

[0069] Preferably, the front end of the longer connection surface along the circumferential direction of the first connection surface 631 and the second connection surface 632 is located above the front end of the shorter connection surface. Water can also be supplied from the first connection surface 631 with a larger amount of water supplied to the second connection surface 632 with a shorter circumferential direction and a smaller amount of water supplied, thereby effectively preventing the generation of an area with a smaller amount of water supplied.

[0070] Preferably, the curvature radius of the longer connecting surface along the circumferential direction of the first connecting surface 631 and the second connecting surface 632 is smaller than the curvature radius of the shorter connecting surface (larger curvature). In this case, since a large centrifugal force is easily generated in the water flow flowing on the long connecting surface along the circumferential direction, the amount of water flowing from the middle of the connecting surface to the circumferential surface can be reduced, and a large amount of water can be guided and supplied to the front end.

[0071] The upper wall 71 is preferably provided with a second through hole 66 located in a region adjacent to the surface of the lower wall 72 on the side of the first through hole 65. According to this configuration, the wall surface of the lower wall 72 can be properly cleaned by the water flowing out of the second through hole 66, so that the wall surface of the lower wall 72 can be kept clean. From the viewpoint of keeping the wall surface of the lower wall 72 cleaner, it is preferred that a plurality of second through holes 66 are formed at intervals along the edge of the first through hole 65. According to this configuration, a wider range of the wall surface of the lower wall 72 can be cleaned.

[0072] The lower wall 72 may be disposed outside the entire first through hole 65, but from the same perspective as above, it may be disposed outside a portion. In this case, the plurality of second through holes 66 are preferably disposed so that the ratio of the area where the second through holes 66 are disposed in the circumferential direction of the first through hole 65 is lower in the area where the lower wall 72 is not disposed than in the area where the lower wall 72 is disposed.

[0073] Preferably, the upper wall 71 is connected to the lower wall 72 via a connecting portion, and the connecting portion has a larger inclination angle relative to the height direction than the upper portion of the upper wall located above the connecting portion. According to this structure, water can easily pass through the second through hole 66, and a high water flow can be ensured even on the downstream side of the second through hole 66.
