The 1 st bottom surface 411 is located at the front side of the cartridge 40, while the 2 nd bottom surface 412 is located at the rear side of the cartridge 40. The area of the 1 st bottom surface portion 411 is set larger than the area of the 2 nd bottom surface portion 412. The 1 st bottom surface 411 is formed as: slowly inclines in a direction of descending from the front to the rear. In addition, the vicinity of the center in the left-right direction of the 1 st bottom surface 411 is formed as: for example, a dome shape that bulges upward.

Rear face 42 is constituted by: the rear, i.e. the rear wall, of the water filling cartridge 40. The rear face portion 42 is formed as: the bottom surface 41 is raised from the rear end of the 2 nd bottom surface 412. The side surface portion 43 is configured: the side surfaces of the water filling box 40 are left and right side wall portions. The side surface portion 43 includes: a 1 st side surface portion 431 and a 2 nd side surface portion 432. The 1 st side surface portion 431 and the 2 nd side surface portion 432 face each other. The 1 st side surface portion 431 is located at a left side position when the cartridge 40 is seen from the front, and the 2 nd side surface portion 432 is located at a right side position when the cartridge 40 is seen from the front. In the present embodiment, between the 1 st side surface portion 431 and the 2 nd side surface portion 432, there is provided: wall portions 44 opposed to the rear face portions 42. The wall portion 44 extends in a direction intersecting the direction in which the side portions 431, 432 extend. The wall portion 44 is formed as: and stands substantially vertically from the front end of the 2 nd bottom surface portion 412. In this case, the 1 st bottom surface portion 411 is formed as: is connected to an end of the wall 44. That is, the wall portion 44 connects the 1 st bottom surface portion 411 and the 2 nd bottom surface portion 412.

In the water filling box 40, a space S in which water can be stored is formed by the 2 nd bottom surface portion 412, the rear surface portion 42, the side surface portion 43, and the wall portion 44. In addition, for example, as shown by arrows in fig. 4 and 5, water flows in the space S. As shown in fig. 4, the water injection cartridge 40 includes: an inflow port 45 and an outflow port 46. The inflow port 45 and the outflow port 46 communicate the inside with the outside of the water injection cartridge 40. The inlet 45 and the outlet 46 are disposed at positions not facing each other.

The inflow port 45 is formed through the 1 st side portion 431 in the thickness direction. The inflow port 45 is connected to the water supply valve 31 via a water supply hose, not shown. The inflow port 45 is: the water flowing from the outside of the water injection case 40 flows into the inside. The outflow port 46 is formed through the wall portion 44 in the thickness direction. The outflow opening 46 is connected to the water filling hose 34. The outflow port 46 is: a portion through which water flows out from the inside of the water injection case 40. That is, the outflow port 46 has: the water flowing into the space S from the inflow port 45 is injected into the outer tank 21.

As shown in fig. 4, the water injection cartridge 40 is configured to: the treatment agent cartridges 32 and 33 can be accommodated through the front opening 401 of the water injection cartridge 40. The treatment agent cartridges 32 and 33 are disposed on the 1 st bottom surface 411 in a state of being accommodated in the water filling cartridge 40. The process agent cartridges 32 and 33 have siphoning portions 321 and 331, respectively. The water mixture obtained by mixing the water supplied into the treatment agent cartridges 32 and 33 with the washing treatment agent flows out of the treatment agent cartridges 32 and 33 through the siphoning portions 321 and 331.

When the water level of the mixed water in the treatment agent tanks 32 and 33 rises by the water supply, the mixed water starts to flow out from the water passages 322 and 332 when the mixed water fills up above the siphoning parts 321 and 331, and thereafter flows down the treatment agent tanks 32 and 33 by the siphon principle, and the outflow of the mixed water is maintained. The mixed water flowing out from the treatment agent cartridges 32 and 33 flows through the 1 st bottom surface 411, and is then supplied into the outer tank 21 from the inflow port 45 through the space S. In addition, when the wash aid to be put into the process cartridges 32 and 33 is assumed to be in powder form, the process cartridges 32 and 33 may be configured without the siphoning portions 321 and 331.

When the amount of water supplied to the process cartridges 32 and 33 is large, water may overflow from above the process cartridges 32 and 33. As described above, since a part of the 1 st bottom surface 411 is formed in a dome shape, water overflowed from above the process cartridge 32, 33 flows toward the outside of the 1 st bottom surface 411. Thereafter, the water flows downward along the surface of the 1 st bottom surface 411, and is supplied from the inflow port 45 to the outer tank 21 through the space S.

The water injection cartridge 40 is provided with a barrier 50 and a protruding portion 60. The barrier 50 and the protruding portion 60 are formed integrally with the water injection cartridge 40, for example, by a synthetic resin. The barrier 50 and the protruding portion 60 are not limited to being formed integrally with the water injection cartridge 40, and may be formed separately from the water injection cartridge 40. In this case, the barrier 50 and the protruding portion 60 are fixed to the water injection case 40 by, for example, an adhesive agent or the like. The obstacle 50 and the protruding portion 60 are located between the 1 st side surface portion 431 and the 2 nd side surface portion 432 in the left-right direction, and include: the water flow can be reduced by contact with the water flowing into the water injection case 40 from the inflow port 45. The barrier 50 and the protruding portion 60 are formed in different shapes.

The obstacle 50 is formed as: the 2 nd bottom surface 412 extends along the longitudinal direction of the 1 st side surface 431 and the 2 nd side surface 432. The obstacle 50 has: a function of changing the flow of water flowing into the water injection box 40 to the extending direction of the barrier 50. As shown in fig. 4, the obstacle 50 is configured to: is inclined with respect to the 1 st side 431 in plan view. In this case, the barrier 50 extends obliquely from the 1 st side surface 431 side toward the 2 nd side surface 432 side as it extends forward. That is, the barrier 50 is inclined from the inlet 45 side toward the outlet 46 side in plan view.

The barrier 50 is provided in: the length of the barrier 50 at a position facing the inflow port 45 is set to be: is larger than the width dimension of the inflow opening 45. In this case, as shown in fig. 6, an end surface 501 of one side of the barrier 50 in the longitudinal direction faces the outflow port 46. On the other hand, the other end surface 502 of the barrier 50 in the longitudinal direction is connected to the rear surface 42. Accordingly, the water flowing into the water injection cartridge 40 from the inflow port 45 can be smoothly guided toward the outflow port 46 along the surface of the 1 st side surface 431 side of the barrier 50.

The barrier 50 also horizontally isolates a part of the space S in the water injection case 40. In this case, the 2 nd bottom surface portion 412 has, as shown in fig. 4: an upstream side bottom surface portion 412a and a downstream side bottom surface portion 412b. The upstream bottom surface portion 412a is located between the 1 st side surface portion 431 and the obstacle 50 in the left-right direction. A portion of the rear side of the upstream side bottom surface portion 412a is formed as: for example, from the rear to the front and downward. Accordingly, the water on the upstream bottom surface 412a can easily flow to the outflow port 46 side, which is the wall 44 side. The downstream bottom surface portion 412b is located between the barrier 50 and the 2 nd side surface portion 432 in the left-right direction. In the space S, the region on the upstream side bottom surface portion 412a side is set as: slightly larger than the downstream bottom surface portion 412b side. As shown in fig. 5, the upstream side bottom surface portion 412a and the downstream side bottom surface portion 412b are located: and is positioned further downward than the upper end 503 of the barrier 50.

The barrier 50 has a water passage 51. The water passage 51 is located: the barrier 50 is formed so that water can pass through the barrier at a position lower than the upper end 503 thereof. In the present embodiment, as shown in fig. 4 and 6, the water passage 51 is formed at the upper end 503 of the barrier 50, and the water passage 51 is formed by a plurality of grooves 511 formed at predetermined intervals. The groove 511 is formed by cutting downward from the upper end 503 of the barrier 50. A convex portion 512 is formed between the adjacent groove portions 511. In fig. 4 and the like, for ease of viewing the drawings, only 1 is given the symbol of the groove 511 and the convex portion 512, and the symbol of the other groove 511 and convex portion 512 is omitted. The water passage 51 is not limited to a shape cut downward from the upper end 503 of the barrier 50, and may be an opening formed by penetrating the barrier 50 in the thickness direction.

As shown in fig. 5, the upper end 503 of the obstacle 50 is located: and is located above the upper end of the inflow port 45. The lower end of the groove 511 is located: and is located above the upper end of the inflow port 45. That is, the water passage 51 is located: and is located above the upper end of the inflow port 45. Thus, a part of the water flowing from the inflow port 45 into the space S in the water injection case 40 comes into surface contact with the lower side of the water passage 51 of the barrier 50, moves upward, passes through the water passage 51, and flows into the region on the downstream side bottom surface portion 412b side in the space S. In this way, by passing water through the water passage 51 formed in the upper portion of the barrier 50, it is possible to suppress: the water contacting the obstacle 50 may bounce upward of the obstacle 50.

As shown in fig. 4, a plurality of protruding portions 60 are provided at positions between the inflow port 45 and the barrier 50 in the left-right direction and at predetermined intervals from each other at the upstream bottom surface portion 412 a. The plurality of protruding portions 60 are provided in: opposite to the inflow port 45. The protruding portion 60 is formed in a columnar shape, for example, a columnar shape, and protrudes upward from the upstream bottom surface portion 412 a. The plurality of projections 60 are formed of a plurality of rows. Each column is configured to: the plurality of protrusions 60 are spaced apart from each other by a predetermined interval along the front-rear direction of the water injection cartridge 40. The predetermined intervals of the plurality of projections 60 may be equal intervals or unequal intervals. In fig. 4 and the like, for easy viewing of the drawing, only the symbol of the projection 60 is given to 1, and the symbol of the other projection 60 is omitted.

The plurality of rows may be formed of 3 or more rows, for example, and may be arranged in a staggered manner on the upstream bottom surface portion 412 a. The interlaced shape is represented by: the plurality of projections 60 included in one row are positioned between the plurality of projections 60 included in the other row adjacent to the one row when viewed from the left-right direction. Further, the plurality of protruding portions 60 are provided on: a position overlapping the obstacle 50 when viewed from the left-right direction. Accordingly, the water flowing from the inflow port 45 to the barrier 50 passes between the 2 protruding portions 60 located in the row on the upstream side and then contacts the protruding portions 60 located in the row on the downstream side. Accordingly, the flow of water is dispersed when passing through each of the plurality of rows, and therefore, the water potential in contact with the obstacle 50 can be reduced.

As shown in fig. 5, the upper end 601 of the protruding portion 60 is located: and is positioned further downward than the upper end 503 of the barrier 50. In addition, the upper end 601 of the projection 60 is located: the water passage 51 of the obstacle 50 is at a position at substantially the same height as the lower end of the groove 511. Further, the upper end 601 of the projection 60 is located: and is located above the upper end of the inflow port 45. Accordingly, the water flowing into the space S from the inflow port 45 can be appropriately brought into contact with the protruding portion 60.

According to the embodiment described above, the washing machine 1 includes: an outer tank 21, a rotary tank 22, and a water injection device 30. The outer tub 21 and the rotary tub 22 can accommodate clothes. The water injection device 30 has a water injection cartridge 40. The water filling box 40 receives water supplied from an external water source and fills the outside tank 21 and the rotary tank 22 with water. The water filling box 40 has: a 1 st side surface portion 431 and a 2 nd side surface portion 432 facing each other. The 1 st side portion 431 is formed with: an inflow port 45 for inflow of water into the water injection case 40. Further, between the 1 st side surface portion 431 and the 2 nd side surface portion 432, there is provided: an obstacle 50 contacting with water flowing into the water filling box 40 from the inflow port 45.

Accordingly, by providing the barrier 50 between the 1 st side surface portion 431 and the 2 nd side surface portion 432, the water flowing into the water injection case 40 from the inflow port 45 formed in the 1 st side surface portion 431 is brought into contact with the barrier 50, and the water potential of the water can be reduced. Accordingly, suppression of: when the water contact flowing into the water filling box 40 hits the 2 nd side surface 432, the water springs upward and overflows to the outside of the water filling box 40.

The barrier 50 is provided in: opposite to the inflow port 45. Accordingly, water flowing into the water injection case 40 from the inflow port 45 can easily contact the barrier 50. Accordingly, the water potential of the water flowing into the water injection case 40 from the inflow port 45 can be effectively reduced.

The barrier 50 is formed with: the water passage 51 for allowing water to pass to a portion below the upper end 503 of the barrier 50. Accordingly, the water contacting the obstacle 50 can be moved from the water passage 51 toward the 2 nd side surface 432 side without bouncing upward to the upper end 503 of the obstacle 50. Accordingly, suppression of: the water contacting the obstacle 50 bounces upward, and the water potential of the water can be effectively reduced.

The water passage 51 is formed by a groove 511 formed at the upper end 503 of the barrier 50. Accordingly, the groove 511 is provided at the upper end 503 of the barrier 50 to form a so-called comb shape, so that water contacting the barrier 50 is prevented from bouncing upward and passing between the grooves 511. Accordingly, the water potential of the water can be reduced more effectively.

The obstacle 50 is configured to: is inclined with respect to the 1 st side 431 in plan view. Accordingly, when the obstacle 50 is disposed orthogonal to the water flow flowing into the water injection cartridge 40 from the inflow port 45, for example, the water contacting the obstacle 50 is likely to bounce upward. Therefore, by disposing the barrier 50 so as to be inclined with respect to the 1 st side portion 431, it is possible to suppress: the water flowing into the water injection case 40 is in contact with the obstacle 50.

In addition, the water injection cartridge 40 has a wall portion 44. The wall 44 is raised from the bottom surface 41 of the water filling cartridge 40, and extends between the 1 st side surface 431 and the 2 nd side surface 432. The wall portion 44 is formed with: an outflow port 46 through which water in the water injection cartridge 40 flows out. The barrier 50 is inclined from the inlet 45 side toward the outlet 46 side in plan view. Accordingly, the water flowing into the water injection cartridge 40 from the inflow port 45 can be guided to the outflow port 46 through the barrier 50. Accordingly, water is less likely to remain in the water injection case 40, and water can be smoothly supplied into the outer tank 21 and the rotary tank 22.

The end surface 501 of one side of the barrier 50 in the longitudinal direction faces the outflow port 46. Accordingly, the water contacting the obstacle 50 can be easily caused to flow to the outflow port 46. Accordingly, the water in the water injection cartridge 40 can be more efficiently discharged.

The length dimension of the barrier 50 is set as: is larger than the width dimension of the inflow opening 45. Accordingly, the water flowing into the water injection cartridge 40 from the inflow port 45 can be appropriately brought into contact with the obstacle 50. Accordingly, the water potential of the water can be effectively reduced.

The upper end 503 of the barrier 50 is located: and is located above the upper end of the inflow port 45. Accordingly, the water flowing into the water injection cartridge 40 from the inflow port 45 can be appropriately brought into contact with the obstacle 50. Accordingly, the water potential of the water can be effectively reduced.

The bottom surface 412b of the water injection cartridge 40 located between the barrier 50 and the 2 nd side surface portion 432 is located: and is positioned further downward than the upper end 503 of the barrier 50. Accordingly, the water flowing through the obstacle 50 flows on the bottom surface 412b to the 2 nd side surface 432. By causing water to flow on the bottom surface 412b in this way, the water potential of water flowing to the 2 nd side surface 432 can be suppressed. Accordingly, it is possible to further suppress: the water bounces upward of the 2 nd side surface portion 432, and overflows to the outside of the water injection case 40.

The water injection cartridge 40 is provided with a protrusion 60. The protruding portion 60 protrudes upward from the bottom surface 412 of the water injection cartridge 40 between the inflow port 45 and the barrier 50. Accordingly, the water potential of the water in contact with the obstacle 50 can be suppressed by the protruding portion 60. Accordingly, the water potential of the water can be reduced more effectively.

(embodiment 2)

Next, embodiment 2 will be described with reference to fig. 7 and 8. Embodiment 2 differs from embodiment 1 in the configuration of the barrier 50. Specifically, in the present embodiment, the barrier 50 has the communication portion 52. As shown in fig. 7, the communication portion 52 is formed in: for example, water can pass through the communication portion 52 at a position below the water passage portion 51 and separated from the water passage portion 51. In this case, the barrier 50 is configured as: water can pass through the plurality of grooves 511 and the communication portion 52. As shown in fig. 8, the communication portion 52 is located: and is located further downward than the lower end of the inflow port 45. The communication portion 52 is formed as: from, for example, the lower end of the obstacle 50 to above. The communication portion 52 may be formed to penetrate the barrier 50 in the thickness direction. The obstacle 50 may be: the structure does not have the water passage 51 but has only the communication 52.

According to embodiment 2 as described above, the obstacle 50 includes: the communication portion 52 formed in the water injection case 40 below the lower end of the inflow port 45 allows water to pass through the portion of the barrier 50 near the lower portion to the downstream side. Accordingly, after the water potential of the supplied water is reduced by the obstacle 50, the water can pass through the communication portion 52 and be guided to the downstream side. In addition, by making water pass from the communication portion 52 to the downstream side, it is possible to suppress: the water contacting the obstacle 50 bounces upward.
