[0008] 1 is a perspective view showing a washing machine 1. In the following description, the front side, the rear side, the width direction (left and right direction), the depth direction (front and back direction), the up and down direction, etc. refer to directions in a state in which the washing machine 1 is installed.

[0009] In this disclosure, the term "washing machine" refers to a general device that performs various processes such as washing on the laundry. Examples of the processes for the laundry include washing, drying, deodorizing, and sterilizing. The laundry is not particularly limited. Examples of the laundry include cloth products. Specific examples of the laundry include clothing such as clothes, hats, and gloves, belongings such as shoes, bags, handkerchiefs, and towels, bedding such as curtains, blankets, towel blankets, and futon covers, carpets, stuffed toys, and the like.

[0010] The washing machine 1 includes a washing machine main body 10. The washing machine main body 10 has a housing in which an internal space is formed to accommodate the components of the washing machine 1. A tub 11 is disposed in the internal space of the housing. In this embodiment, an example will be described in which the washing machine 1 is a so-called drum-type washing machine in which the tub is disposed so that the central axis of the tub 11 extends along a direction inclined with respect to the vertical direction. However, the washing machine 1 of the present disclosure is not limited to a drum-type washing machine, and may be, for example, a washing machine in which the central axis of the tub is disposed along a horizontal direction or a direction inclined with respect to the horizontal direction when the washing machine is installed.

[0011] An input port for putting in and taking out laundry such as clothes is provided on the front surface of the washing machine main body 10. A door 12 capable of opening and closing the input port is rotatably attached to the front surface of the washing machine main body 10.

[0012] A water supply section 13, a chemical dispenser section 2, and the like are provided on the top surface of the washing machine main body 10. A water supply source such as a water line is connected to the water supply section 13, and a water supply valve (not shown) provided inside the washing machine main body 10 is connected to the water supply section 13. Chemicals to be supplied to the tub 11 are dispensed into the chemical dispenser section 2. The chemicals refer to detergents used in the washing machine 1, and include various laundry detergents such as liquid detergent, powder detergent, and fabric softener. The chemical dispenser section 2 has an openable lid 3 on the top surface. When the lid 3 is opened, a storage section 4 and a chemical dispenser case 5, which will be described later, are exposed.

[0013] Fig. 2 is a perspective view showing the container 4 and the medicine supply case 5 provided in the medicine supply section 2. Fig. 3 is an exploded perspective view of the container 4 and the medicine supply case 5.

[0014] The washing machine main body 10 is provided with a storage section 4 and a drug supply case 5 inside the washing machine main body 10 as the drug supply section 2. An internal space is formed within the storage section 4 to store the drug supply case 5. In this embodiment, as shown in Fig. 3, the storage section 4 is a recess that opens upward.

[0015] The storage section 4 is, in plan view, a generally rectangular shape that is long in the front-rear direction of the washing machine main body 10, and is polygonal. The polygonal shape includes polygons with chamfered or rounded corners. The polygonal shape also includes polygons with at least one side formed by a curve. The rectangle shape includes not only a rectangular shape but also a square shape.

[0016] The storage unit 4 has an inclined surface at the bottom to provide a water flow gradient. A drain port 45 is opened at the bottom inside the storage unit 4 on the underwater side. A first supply port 41 and a second supply port 42, which are openings for connecting a water supply pipe, are provided on a side wall 40 of the storage unit 4. The first supply port 41 and the second supply port 42 are both provided in a circular shape and are formed with a gap between them.

[0017] An outwardly protruding flange 43 is provided on the upper edge of the storage section 4. The flange 43 is used to fix the storage section 4 to the washing machine body 10, and has a plurality of screw holes. A step 44 is provided on the inner periphery of the flange 43 below the flange 43 and extends horizontally.

[0018] As shown in Fig. 3, the medicine injection case 5 is formed so as to be able to be housed in the housing section 4. An outwardly protruding flange 55 is provided on the upper edge of the medicine injection case 5. The flange 55 is formed in a brim shape extending outward. The flange 55 is disposed above the step section 44 of the housing section 4. The flange 55 is not limited to being brim-shaped, and may be formed in any shape so long as it protrudes outward from the medicine injection case 5.

[0019] The drug supply case 5 has a wall 50 connected to a flange 55. The drug supply case 5 includes a supply section 6 through which the drug is supplied. When the drug supply case 5 is accommodated inside the accommodation section 4, the wall 50 is located between the supply section 6 of the drug supply case 5 and the inner surface of the accommodation section 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 third supply port 53 has a circular shape in a plan view and has the same diameter as the first supply port 41. The fourth supply port 54 has a circular shape in a plan view and has the same diameter as the second supply port 42. In this embodiment, the fourth supply port 54 has a larger diameter opening than the third supply port 53.

[0021] The third supply port 53 and the fourth supply port 54 are provided at positions respectively corresponding to the first supply port 41 and the second supply port 42 of the storage unit 4. When the medicine injection case 5 is stored in the storage unit 4, the first supply port 41 and the third supply port 53 match, and the second supply port 42 and the fourth supply port 54 match, allowing water to flow from the water supply pipes connected thereto.

[0022] A removable restricting portion 57 is provided on a part of the wall portion 50 of the medicine injection case 5. The restricting portion 57 is disposed from the upper edge of the medicine injection case 5 to the inside of the wall portion 50 where the third supply port 53 and the fourth supply port 54 are provided.

[0023] The restricting portion 57 includes a first contact plate 571 facing the third supply port 53 and a second contact plate 572 facing the fourth supply port 54. The first contact plate 571 and the second contact plate 572 are formed to bulge toward the inside of the supply portion 6 and are plate-shaped portions extending obliquely downward. The restricting portion 57 is attached to the wall portion 50 of the medicine injection case 5, so that the third supply port 53 and the fourth supply port 54 are covered and hidden by the restricting portion 57.

[0024] When the restricting portion 57 is attached to the medicine feed case 5, a gap is formed between the first contact plate 571 and the wall portion 50, and the gap is open downward. Also, a gap is formed between the second contact plate 572 and the wall portion 50, and the gap is open downward. The second contact plate 572 has a notch 573 on the side opposite to the first contact plate 571 side. Since the restricting portion 57 has the notch 573, the gap between the second contact plate 572 and the wall portion 50 is also open to the side of the fourth supply port 54. The side of the second contact plate 572 does not contact the wall portion 50, but is separated therefrom.

[0025] As shown in FIG. 2, the medicine injection case 5 includes a first supply section 601 and a second supply section 602 as the supply section 6. The first supply section 601 and the second supply section 602 are partitioned by an inner wall 56 extending in the vertical direction and are spaced apart from each other. Both the first supply section 601 and the second supply section 602 are formed in a shape that opens upward and is recessed downward. The first supply section 601 and the second supply section 602 may each be, for example, cylindrical, elongated cylindrical, or elliptical cylindrical.

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

[0027] The first contact plate 571 of the regulating portion 57 is provided corresponding to the first supply portion 601, and the second contact plate 572 is provided corresponding to the second supply portion 602. The regulating portion 57 regulates the water flowing in from the third supply port 53 to come into contact with the inner surface of the first contact plate 571 of the regulating portion 57, change the flow downward, and flow into the first supply portion 601. 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, and also flows to the side of the fourth supply port 54 through the cutout 573, 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 an agent. The water and the agent 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 612. In the second supply section 602, for example, liquid detergent or powder detergent is put as an agent. The water and the agent 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 through hole 65. The mixed water is discharged from the first supply section 601 or the second supply section 602 to the storage section 4 and supplied to the tub 11 through the drain port 45 of the storage section 4.

[0029] FIG. 4 is a plan view showing the medicine injection case 5. The flow of water in the second supply section 602 will be generally described with reference to FIG. 4. Water is supplied to the second supply section 602 from the water supply section 13 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 also flows into the second supply section 602 from the side of the fourth supply port 54 through the notch 573. The supplied water is configured to flow in the circumferential direction along the inner peripheral surface of the second supply section 602. Details will be described later.

[0030] Fig. 5 is a plan view showing the medicine feed case 5 with the restricting portion 57 removed. Figs. 6 to 9 are cross-sectional views of the medicine feed case 5 shown in Fig. 4, with Fig. 6 being a cross-sectional view taken along line AA, Fig. 7 being a cross-sectional view taken along line BB, Fig. 8 being a cross-sectional view taken along line CC, and Fig. 9 being a cross-sectional view taken along line DD. In Figs. 4, 5, and Fig. 10 described later, openings (through holes) penetrating from the inside to the outside are shown in light black.

[0031] As shown in FIG. 5, an opening 67 is formed in the wall 50 of the drug supply case 5, the opening 67 being connected to the first supply section 601 or the second supply section 602 and the outside of the drug supply case 5. In the drug supply case 5 according to this embodiment, a plurality of openings 67 is provided in the wall 50. The first supply section 601 is provided with a plurality of openings 67 in a region below the third supply port 53. In addition, one opening 67 is provided in a surface facing the third supply port 53. The second supply section 602 is provided with a single opening 67 in a region below the fourth supply port 54. The water supplied to the drug supply case 5 is configured to flow to the outside of the drug supply case 5 through the plurality of openings 67.

[0032] The configuration of the second supply section 602 provided in the medicine injection case 5 will be described in more detail. As shown in Fig. 6, the medicine injection case 5 has a peripheral surface 60 and a bottom surface 64 which constitute the second supply section 602. A first through hole 65 which connects the second supply section 602 to the outside of the medicine injection case 5 is formed in the bottom surface 64.

[0033] The circumferential surface 60 includes a first circumferential surface 61 located in an area where the fourth supply port 54 (hereinafter simply referred to as the supply port 54) is formed in the height direction X, and a second circumferential surface 62 located below the first circumferential surface 61. Furthermore, the circumferential surface 60 of the second supply section 602 has connection surfaces (631, 632) that connect the first circumferential surface 61 and the second circumferential surface 62.

[0034] 5, in a plan view, a first connection surface 631, which is one of the connection surfaces constituting the peripheral surface 60, extends along the peripheral direction from one side in the width direction (horizontal direction) of the center of the supply port 54. The first connection surface 631 is formed so that the angle it forms with the horizontal direction perpendicular to the height direction X is smaller than that of the first peripheral surface 61.

[0035] The second connection surface 632, which is the other of the connection surfaces constituting the peripheral surface 60, extends along the peripheral direction from the other side in the width direction of the center of the supply port 54. The second connection surface 632 is also formed so that the angle it forms with the horizontal direction perpendicular to the height direction X is smaller than that of the first peripheral surface 61.

[0036] The second connection surface 632 has a different length in the circumferential direction than the first connection surface 631. In the medicine injection case 5 according to this embodiment, the second connection surface 632 is formed to be shorter in the circumferential direction than the first connection surface 631. The first connection surface 631 is formed to be longer in the circumferential direction than the second connection surface 632.

[0037] In a plan view, the first connection surface 631 is provided with its starting end at the end on the supply port 54 side and its ending end on the opposite side to the supply port 54 side. The first connection surface 631 has its starting end below the supply port 54, extends in an arc along the circumferential surface 60, and ends near the lower end of one end of the inner wall 56. The first connection surface 631 is provided to a position farthest from the supply port 54 within the second supply section 602 and diagonally opposite the supply port 54. The width of the first connection surface 631 is formed to be widest on the supply port 54 side and gradually narrower.

[0038] In a plan view, the second connection surface 632 is provided with its start end at the end on the supply port 54 side and its end end on the opposite side to the supply port 54 side. As shown in Fig. 6, the start end of the second connection surface 632 is provided away from the start end of the first connection surface 631. In addition, the start end of the second connection surface 632 is located below the second contact plate 572 of the restriction portion 57.

[0039] 5, the second connection surface 632 extends along the circumferential surface 60 and terminates near the lower end of one end of the inner wall 56. The second connection surface 632 also extends to a position diagonally opposite the supply port 54, which is the furthest from the supply port 54. The second connection surface 632 has a shorter length along the circumferential direction than the first connection surface 631. The width of the second connection surface 632 is widest on the supply port 54 side and gradually narrows.

[0040] In plan view, the width of the end portion (width on the starting end side) of the first connection surface 631 on the supply port 54 side is set wider than the width of the end portion (width on the starting end side) of the second connection surface 632 on the supply port 54 side. The circumferentially curved shapes of the first connection surface 631 and the second connection surface 632 can be regarded as a continuation of a substantially arc-shaped plane including a part of the circumference of a virtual circle centered on a point on an axis along the height direction X of the supply unit 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 larger degree of curvature in plan view than the second connection surface 632.

[0041] 6, the start end of the first connection surface 631 and the start end of the second connection surface 632 are also spaced apart in the height direction X and are provided at different height positions. Also, as shown in FIG. 7, the end end of the first connection surface 631 and the end end of the second connection surface 632 are provided at different positions in the height direction X and are spaced apart. The end end of the first connection surface 631 and the end end of the second connection surface 632 are provided so as not to overlap in the height direction X. In this embodiment, the end end of the first connection surface 631 is provided above the end end of the second connection surface 632.

[0042] The first connecting surface 631 is an inclined surface having a gentler gradient in the circumferential direction than the second connecting surface 632. The first connecting surface 631 is formed with an average gradient angle with respect to the horizontal direction smaller than that of the second connecting surface 632. The second connecting surface 632 is an inclined surface having a steeper gradient in the circumferential direction than the first connecting surface 631.

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

[0044] 6, second contact plate 572 of restriction portion 57 provided opposite supply port 54 has a single rib 574 on its inner surface. Rib 574 protrudes from second contact plate 572 in the direction of supply port 54. When restriction portion 57 is attached to medicine injection case 5, rib 574 is disposed opposite supply port 54 and is provided sloping downward from the other side in the width direction of the center of supply port 54 toward first connection surface 631.

[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 onto 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 flows from the supply port 54 toward the first connection surface 631. Water flows in 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. More water flows into the first connection surface 631 side provided close to the supply port 54 than into the second connection surface 632 side. The first connection surface 631 is provided with a wide width on the starting end side, so that more water can flow.

[0046] 4, the water flowing on the first connection surface 631 flows in an arc shape along the circumferential direction on the first connection surface 631. Centrifugal force acts on the water flowing in an arc shape on the first connection surface 631 where more water flows. As shown in FIG. 8, the water subjected to the centrifugal force does not easily flow down from the first connection surface 631, which has a gentle slope, to the second circumferential surface 62, and flows while circulating in the circumferential direction on the first connection surface 631. As shown in FIG. 9, the water flows to the end of the first connection surface 631 and flows downward.

[0047] 7, water flowing on second connecting surface 632 flows circumferentially at a steeper gradient and for a shorter distance than on first connecting surface 631. The water flows to the end of second connecting surface 632 and then flows downward.

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

[0049] This allows water to flow to a portion away from the supply port 54 where water does not easily flow. The end of the first connection surface 631 and the end of the second connection surface 632 are provided so as not to overlap in the height direction X, so that excessive water does not flow to one place. The water that has flowed through the first connection surface 631 and the second connection surface 632 flows downward while washing the inner surface of the second supply part 602, and is discharged from the first through hole 65. Even if the second supply part 602 has a drug or mixed water attached thereto, the first connection surface 631 and the second connection surface 632 can be washed away by the flowing water. Dirt is likely to occur at a position away from the supply port 54, but since the water flowing through the first connection surface 631 and the water flowing through the second connection surface 632 are both located at a position where they flow down, it is possible to prevent dirt from occurring and keep the second supply part 602 clean.

[0050] The connection surface connecting the first peripheral surface 61 and the second peripheral surface 62 is not limited to the form shown in the example. The medicine injection case 5 may be configured such that one of the first connection surface 631 and the second connection surface 632 is provided, and water flows in one circumferential direction, and the water may flow in a vortex shape. The connection surface may be provided not only in the second supply part 602 but also in the first supply part 601 in the same manner.

[0051] The medicine supply case 5 according to this embodiment is configured so as to be capable of preventing the occurrence of contamination not only on the inner surface but also on the outer surface of the supply section 6 into which the medicine is supplied.

[0052] 6, the second supply section 602 has an upper wall 71 constituting the bottom surface 64 and the second circumferential surface 62, and a lower wall 72 extending downward from the outer surface of the upper wall 71. The lower wall 72 is provided away from the first through hole 65 and disposed so as to surround at least a portion of the first through hole 65. In this embodiment, the lower wall 72 surrounds more than half of the outer periphery of the first through hole 65 and is open to the first supply section 601 side (the drain outlet 45 side of the storage section 4).

[0053] 10 is a bottom view of medicine injection case 5. As shown in the figure, in a plan view, bottom wall 72 is provided outside a portion of first through-hole 65 and is not positioned outside peripheral surface 60. Bottom wall 72 is disposed in a substantially U-shape surrounding first through-hole 65.

[0054] As described above, in the medicine supply case 5, the first through hole 65 is formed in the bottom surface 64 of the second supply part 602 so as to open and connect the second supply part 602 to the outside of the medicine supply case 5. As shown in Fig. 5 and Fig. 10, in addition to the first through hole 65, the second supply part 602 is also provided with a second through hole 66.

[0055] The second through hole 66 is provided in the upper wall 71. The second through hole 66 is an opening that connects the second supply section 602 to the outside of the medicine injection case 5. The second through hole 66 is located in an inner region of the lower wall 72 adjacent to the surface of the lower wall 72 on the first through hole 65 side, and a plurality of second through holes 66 are formed along the edge of the first through hole 65 in a plan view. The 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 in the second supply unit 602. Each second through hole 66 is provided in a long and narrow slit shape in a plan view, and has a rectangular or arc shape. The first through hole 65 has a larger opening area than the second through hole 66, and opens in a circular shape.

[0057] The second through holes 66 are provided such that, in the circumferential direction of the edge of the first through hole 65, the proportion of the area in which the second through holes 66 are provided is lower in an area in which the lower wall 72 is not provided than in an area in which the lower wall 72 is provided. In the example shown in Fig. 10, the second through holes 66 are located in the area in which the lower wall 72 is provided, and there are no second through holes 66 in the area in which the lower wall 72 is not provided.

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

[0059] In the second supply section 602, the water and the medicine supplied via the supply port 54 are mixed and discharged from the first through hole 65. When the medicine feeding case 5 is housed in the storage section 4, the bottom wall 72 is disposed inside the storage section 4. Outside the second supply section 602, the area below the first through hole 65 and the inner surface of the storage section 4 are partitioned by the bottom wall 72. The provision of the bottom wall 72 can prevent the water discharged from the first through hole 65 from splashing onto the inner surface of the storage section 4.

[0060] As shown in FIG. 8, in the region below the first through-hole 65 defined by the lower wall 72, water is not only drained from the first through-hole 65 but also drained from the multiple second through-holes 66. The water drained from the second through-hole 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 with the lower wall 72, and the inclination angle is large at 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 reaches the back side of the bottom surface 64. This makes it possible to wash the outside of the second supply part 602 and the inner surface of the lower wall 72 in the region below the first through-hole 65, and prevents the generation of dirt.

[0061] In addition, the second through-hole 66 may be provided in an area of ​​the medicine injection case 5 where the bottom wall 72 is not provided, and is not limited to the illustrated form. The size, shape, number, etc. of the second through-hole 66 are also not limited, and the second through-hole 66 may be formed in any manner as long as it is an opening located in an area adjacent to the first through-hole 65.

[0062] In the washing machine 1, the chemical feed case 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 unit 6. This allows the water flow to be effectively supplied to a wide area of ​​the circumferential surface of the supply unit 6 to which the chemicals are supplied. This makes it difficult for chemicals to remain in the supply unit 6, and the supply unit 6 can be kept clean.

[0063] From the viewpoint of making the area to which the water flow is supplied wider, it is preferable to provide a connection surface 63 (connection surface 63 is a collective term for connection surfaces including first connection surface 631 and second connection surface 632) that connects first peripheral surface 61 and second peripheral surface 62 and forms an angle with the horizontal direction smaller than that of first peripheral surface 61. With this configuration, the water flow flowing over connection surface 63 can be prevented from falling downward by connection surface 63. Therefore, the area to which the water flow is supplied can be made wider. In this way, connection surface 63 has a function of guiding the water flow, and therefore can also be called a guide 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 having a different length along the circumferential direction from the first connection surface 631. For example, the amount of water supplied may differ between the first connection surface 631 and the second connection surface 632 due to the positional relationship with the supply port 6. By shortening the length along the circumferential direction of the connection surface that supplies a smaller amount of water out of the first connection surface 631 and the second connection surface 632, and lengthening the length along the circumferential direction of the connection surface that supplies a larger amount of water, the water flow can be supplied more uniformly. However, the ratio of the length between the first connection surface 631 and the second connection surface 632 is, for example, preferably 0.1 or more and 0.9 or less, more preferably 0.2 or more and 0.8 or less, and even more preferably 0.3 or more and 0.7 or less.

[0065] Of the first connecting surface 631 and the second connecting surface 632, it is preferable that the one having a relatively shorter circumferential length has a larger average inclination angle with respect to the horizontal direction. By increasing the average inclination angle of the inclined surface having a shorter circumferential length and supplying less water, the flow rate of the water flow can be increased. Therefore, washing can be effectively performed even on the inclined surface to which less water is supplied.

[0066] Of the first connection surface 631 and the second connection surface 632, the connection surface having a longer circumferential length is preferably wider at the end on the supply port 6 side than the connection surface having a shorter circumferential length. This is because it is easier to supply a large amount of water to the tip side in the connection surface having a longer circumferential length.

[0067] It is preferable that the end (tip) of the first connection surface 631 on the opposite side to the supply port 6 and the end (tip) of the second connection surface 632 on the opposite side to the supply port 6 do not overlap in the height direction. In other words, it is preferable that the tip of the first connection surface 631 and the tip of the second connection surface 632 are separated in the circumferential direction. For example, it is preferable 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 prevent the water flow that has flowed on the first connection surface 631 and the water flow that has flowed on the second connection surface 632 from concentrating in one place, which prevents the water flow from being suitably supplied to other parts. As a result, water can be supplied more suitably to the entire circumferential surface.

[0068] It is preferable that the end (tip) of the first connection surface 631 opposite the supply port 6 and the end (tip) of the second connection surface 632 opposite the supply port 6 are located at different positions in the height direction. With this configuration, for example, it is possible to suppress the occurrence of an area where the water flow velocity decreases due to the water flow flowing on the first connection surface 631 and the water flow flowing on the second connection surface 632 colliding head-on. It is possible to supply a water flow with a high flow velocity to a wide area.

[0069] It is preferable that the tip of the connecting surface having a longer circumferential dimension out of the first connecting surface 631 and the second connecting surface 632 is located higher than the tip of the connecting surface having a shorter circumferential dimension. Since water can be supplied from the first connecting surface 631, which supplies a larger amount of water, onto the second connecting surface 632, which has a shorter circumferential dimension and supplies a smaller amount of water, the occurrence of an area where too little water is supplied can be effectively suppressed.

[0070] It is preferable that the radius of curvature of the connecting surface having a longer circumferential dimension out of the first connecting surface 631 and the second connecting surface 632 is smaller (has a larger curvature) than the radius of curvature of the connecting surface having a shorter circumferential dimension. In this case, a large centrifugal force is likely to act on the water flowing on the connecting surface having a longer circumferential dimension, so that the amount of water that flows down 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 tip.

[0071] It is preferable that the upper wall 71 is provided with a second through hole 66 located in an area adjacent to the surface of the lower wall 72 on the first through hole 65 side. With this configuration, the wall surface of the lower wall 72 can be suitably washed with water flowing out from 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 preferable that a plurality of second through holes 66 are formed at intervals from each other along the edge of the first through hole 65. With this configuration, a wider range of the wall surface of the lower wall 72 can be kept clean.

[0072] The lower wall 72 may be provided outside the entire first through hole 65, but from the same viewpoint as above, it may be provided outside only a portion of the first through hole 65. In that case, the multiple second through holes 66 are preferably provided such that the proportion of the area in which the second through holes 66 are provided in the circumferential direction of the first through hole 65 is lower in an area where the lower wall 72 is not provided than in an area where the lower wall 72 is provided.

[0073] The upper wall 71 is connected to the lower wall 72 at a connection portion, and the connection portion preferably has a larger inclination angle with respect to the height direction than the upper portion of the upper wall located above the connection portion. This configuration allows water to easily pass through the second through-hole 66, and ensures a high water flow even downstream of the second through-hole 66.
