The configuration of the detergent case 112 and its surroundings will be described with reference mainly to FIGS.
As shown in FIG. 4, the detergent case 112 includes a powder detergent charging unit 400, a liquid detergent charging unit 401, and a softening agent charging unit 402, and powder detergent, liquid detergent, and soft detergent are used in these places, respectively. Thrown by the person. Although not shown, the water supply apparatus 201 is located immediately above the powder detergent charging unit 400, the liquid detergent charging unit 401, and the softening agent charging unit 402 in a state where the detergent case 112 is stored in the detergent case storage unit 210. Each has a water inlet (not shown). The water supply device 201 is configured to pour water from these water injection ports into the powder detergent charging unit 400, the liquid detergent charging unit 401, and the softening agent charging unit 402. Note that, as described above, the powder detergent charging unit 400 and the liquid detergent charging unit 401 are simultaneously supplied with water according to the opening and closing of the water supply valve 203b. On the other hand, the soft finish agent charging unit 402 is supplied with water according to the opening and closing of the water supply valve 203a.

  The powder detergent charging unit 400 is provided on the back side of the detergent case 112. The powder detergent charging unit 400 is partitioned on the front and left and right by a wall surface, but no wall surface is provided on the back side. When water is poured into the powder detergent charging unit 400 by the water supply device 201, water and detergent flow out from this back side portion and flow downstream.

  The soft finishing agent charging unit 402 is provided on the left front side of the detergent case 112 and includes a siphon mechanism and a soft finishing agent charging auxiliary member 403 (not shown). The user can put the soft finishing agent into the soft finishing agent charging unit 402 through the opening 414 of the soft finishing agent charging auxiliary member 403. When water is poured into the soft finishing agent charging unit 402 by the water supply device 201, the softening agent flows downstream through the siphon mechanism together with water.

  The liquid detergent charging unit 401 is provided on the right front side of the detergent case 112, and an outflow port 411 is provided at the bottom thereof. Lower portions of the four side surfaces 409a to 409d of the liquid detergent charging unit 401 form tapered surfaces 412a to 412d, and the upper portions thereof are vertical wall surfaces. By making the lower part of the side surfaces 409a to 409d of the liquid detergent charging unit 401 into a tapered shape, it is possible to prevent the liquid detergent from remaining in the liquid detergent charging unit 401.

  The liquid detergent charging unit 401 is provided with a flap 404 that opens and closes an upper opening 408 thereof. The hinge axis of the flap 404 is provided along the right edge 409a, and is fastened to the front edge 409c by the hinge pin 405a and to the back edge 409d by the hinge pin 405b. Thereby, since the flap 404 opens toward the outside of the detergent case 112, the liquid detergent can be received in a region wider than the opening 408 of the liquid detergent charging unit 401, that is, a region formed by the opening 408 and the back surface of the flap 404. Yes (see FIG. 5). Therefore, for example, as shown in FIG. 6, the liquid detergent can be introduced along the back surface of the flap 404, and it is difficult for the user to overflow the liquid detergent.

  The liquid detergent charging unit 401 is provided on the right side in the left-right direction in the detergent case 112, that is, on the center side of the housing 100. For this reason, when the liquid detergent is overflowed, the liquid 100 is applied to the housing 100 with a high probability, causing a stain on the design surface of the housing 100 and a solvent crack. Therefore, in the configuration in which the liquid detergent charging portion is provided at the center side of the housing in the detergent case as in the present embodiment, the configuration in which the flap is provided in the liquid detergent charging portion is particularly effective.

  In addition, a finger hook portion 406 is provided on the far left side of the flap 404. The user puts his finger on the finger hook portion 406 and rotates the flap 404 upward about the hinge axis, thereby opening the flap 404 from the closed state (FIG. 4) (FIG. 5). Can be. In the state where the flap 404 is opened, the left and right widths of the detergent case 112 are larger than the left and right widths of the opening 212 of the detergent case accommodating portion 210 and cannot be accommodated in the detergent case accommodating portion 210. On the other hand, when the flap 404 is closed, the left and right widths of the detergent case 112 are reduced, and the detergent case 112 can be accommodated in the detergent case accommodating portion 210.

  As shown in FIG. 6, when the flap 404 is opened, the back surface of the flap 404 is inclined downward toward the opening 408 side. When the user puts the liquid detergent into the liquid detergent throwing portion 401, the liquid detergent may be dropped directly on the opening 408 or may be dropped on the back surface of the flap 404. When a liquid detergent is dropped on the back surface of the flap 404, the liquid detergent flows on the back surface of the flap 404 toward the opening 408 and is introduced into the liquid detergent charging unit 401. That is, by opening the flap 404, the area of the liquid detergent dripping, that is, the area of the opening 408 and the back surface of the flap 404 can be made larger than the area of the opening 408. Thereby, it can prevent that a user overflows a liquid detergent.

  As shown in FIG. 7, when the flap 404 is closed, the base end side portion 416 that is the side portion along the hinge axis of the flap 404 is higher than the free end side portion 417 that is the other side portion facing this. Position. As a result, the surface of the flap 404 is inclined downward from the proximal end side portion 416 side toward the free end side portion 417 side. A gap 418 is formed between the free end side portion 417 and the left side surface 409b. Thus, when water is supplied from above the detergent case 112 as indicated by an arrow P, the water flows on the surface of the flap 404 toward the free end side portion 417 as indicated by an arrow Q. Then, the water that has flowed to the free end side portion 417 side falls downward through the gap 418 as indicated by an arrow R, and then flows downstream through the outflow port 411.

  When the liquid detergent is introduced with the flap 404 closed, the liquid detergent flows downstream through the same path as the water described above. That is, the liquid detergent can be introduced without opening the flap 404. Therefore, the user can arbitrarily select a loading method, that is, a method of opening and closing the flap 404 or a method of loading in a closed state. When the flap 404 is opened and thrown in, as described above, the detergent can be prevented from overflowing. On the other hand, when the flap 404 is closed and thrown in, it is not necessary to open the flap 404, so that the detergent can be thrown in with one operation less.

  According to this embodiment, the detergent case 112 is provided with the flap 404 that opens and closes the liquid detergent charging unit 401. Thereby, when the detergent case 112 is accommodated in the detergent case accommodating part 210, the space occupied by the detergent case 112 can be suppressed. On the other hand, when the detergent case 112 is pulled out from the detergent case storage unit 210, it is possible to prevent the detergent from overflowing outside the liquid detergent charging unit 401 by opening the flap 404.

<Second Embodiment>
The washing machine according to the second embodiment will be described mainly with respect to parts different from the first embodiment with reference to FIGS. 8 and 9.
As shown in FIGS. 8 and 9, a part of the side surface 409d on the back side of the liquid detergent charging unit 401 is notched, thereby forming an overflow portion 413. The overflow part 413 is provided at a position higher than the outlet 411, and connects the liquid detergent charging part 401 and the powder detergent charging part 400. When the water level in the liquid detergent charging unit 401 becomes high, the water in the liquid detergent charging unit 401 overflows into the powder detergent charging unit 400 through the overflow unit 413.

  As shown in FIG. 9, the overflow portion 413 is provided above the back surface of the flap 404 when the flap 404 is closed. As a result, when the water level in the liquid detergent charging unit 401 increases to such an extent that water flows out through the overflow portion 413, the back surface of the flap 404 is exposed to the water. That is, the liquid detergent adhering to the back surface of the flap 404 when the flap 404 is put in an open state is washed away with water.

  The opening area of the outflow port 411 is smaller than the opening area of a water injection port (not shown) used for water injection into the liquid detergent charging unit 401. Thereby, at the time of water injection, the amount of water injected per unit time through the water injection port becomes larger than the amount of outflow per unit time through the outlet 411, so that water accumulates in the liquid detergent charging unit 401. That is, since the water level becomes high enough to allow water to flow through the overflow portion 413, the flap 404 is cleaned as described above.

  According to the present embodiment, the detergent case 112 is provided with the flap 404 that opens and closes the liquid detergent charging unit 401 and the overflow portion 413 that connects the inside and outside of the liquid detergent charging unit 401, and an amount that exceeds the outflow amount by the outlet 411. The water and the liquid detergent are made to flow downstream through the overflow part 413 by supplying the water to the liquid detergent charging part 401. According to this structure, the liquid detergent adhering to the flap 404 can be washed away with water. Thereby, it is possible to prevent the user from feeling uncomfortable by touching or visually recognizing the remaining liquid detergent in the next driving.

<Third embodiment>
The washing machine according to the third embodiment will be described mainly with respect to parts different from the first embodiment with reference to FIGS. 10 and 11.
As shown in FIG. 10, the detergent case 112 of the present embodiment is provided with a soft finish agent charging unit 402, a liquid detergent charging unit 401, and a powder detergent charging unit 400 in order from the front side to the back side. .

  The liquid detergent charging unit 401 is provided with a flap 404 that opens and closes an upper opening 408 thereof. The hinge axis of the flap 404 is provided along the back side surface 409d, and is secured to the left side surface 409b by the hinge pin 405b and to the right side surface 409a by the hinge pin 405a. According to this configuration, the flap 404 opens toward the back side of the liquid detergent charging unit 401 as indicated by a two-dot chain line in FIG. Accordingly, the area of the liquid detergent that can be dropped, that is, the area of the opening 408 and the back surface of the flap 404 can be made larger than the area of the opening 408, and the user is less likely to overflow the liquid detergent.

An outflow port 411 is provided on the lower surface of the liquid detergent charging unit 401. The outflow port 411 is connected to an outflow path 415 that continues to the back side.
As shown in FIG. 11, when the flap 404 is closed, the base end side portion 416 along the hinge axis of the flap 404 is positioned higher than the free end side portion 417 facing the hinge 404. Thereby, the surface of the flap 404 inclines downward from the base end side part 416 side toward the free end side part 417 side facing this. Further, a gap 418 is formed between the free end side portion 417 and the front side surface 409c. Thus, when water is supplied from above the detergent case 112 as indicated by an arrow P, the water flows on the surface of the flap 404 toward the free end side portion 417 as indicated by an arrow Q. Then, the water that has flowed to the free end side portion 417 side falls downward through the gap 418 as indicated by the arrow R, and then flows into the outflow path 415 through the outlet 411 as indicated by the arrow S. Then, the water flowing into the outflow path 415 flows downstream through the outflow path 415 as indicated by an arrow T.

  Furthermore, as shown in FIG. 12, the water supply apparatus 201 of the present embodiment has a contact portion 214 that protrudes toward the front side in the detergent case housing portion 210, and a flap avoidance space 215 in front of the contact portion 214. Is provided. When the detergent case 112 is inserted into the detergent case housing portion 210 with the flap 404 open, the contact portion 214 hits the surface of the flap 404. When the detergent case 112 is further inserted, the flap 404 is pushed by the contact portion 214 and rotates around the hinge shaft to be in a closed state. Here, the flap 404 pushed by the contact portion 214 rotates in the flap avoiding space 215. Therefore, the flap 404 does not interfere with other parts during the rotation.

  According to the washing machine of this embodiment, the rotation axis of the flap 404 is provided on the back side with respect to the direction in which the detergent case 112 is pulled out, and is provided in a direction perpendicular to the pulling direction. Moreover, the washing machine of this embodiment is provided with the contact part which contact | abuts from the back side when accommodating the said flap 404 in a housing | casing. According to this configuration, the detergent case 112 can be accommodated in the detergent case accommodating portion 210 without the user performing an operation of closing the flap 404 himself.

<Other embodiments>
Although the first to third embodiments are shown as drum-type washing machines, they can be applied to other types of washing machines such as a vertical washing machine.

  In the first to third embodiments, the flap 404 has a configuration in which the base end side portion 416 on the hinge side is provided at a position higher than the free end side portion 417 facing this. Instead, the flap may have a configuration in which the base end side portion on the hinge side is higher than the free end side portion facing the flap. Further, the flap may have a configuration in which these two side portions have the same height.

  In the second embodiment, the entire overflow portion 413 is provided at a position higher than the surface of the flap 404. However, this configuration is not essential. That is, as long as the flap 404 is exposed to water, for example, a part of the overflow portion 413 may be at a position lower than the flap 404.

  Moreover, in 2nd embodiment, it was set as the structure where water accumulates in the liquid detergent injection | throwing-in part 401 by making the opening area of the outflow port 411 smaller than the opening area of the water injection opening | mouth of the liquid detergent injection | throwing-in part 401. However, this configuration is not essential. For example, in the configuration in which the water pressure at the water injection port is increased, water is poured into the liquid detergent charging unit 401 even if the opening area of the outlet 411 is not smaller than the opening area of the water injection port of the liquid detergent charging unit 401. Can be stored. Even with such a configuration, the same effect as in the second embodiment can be obtained.

  In the first to third embodiments, the flap 404 is provided in the liquid detergent charging unit 401, but the soft finish agent charging unit 402 may be provided with a flap. In addition, a flap can be provided in the input portion of another liquid clothing treatment agent such as a liquid bleach input portion.
