The container 50 has a front wall 51, a side wall 52, a back wall 53, a bottom 54, and an upper opening 55. The container box 50 can accommodate a plurality of, in this case, two containers 60 therein. In the present embodiment, two containers 60 are housed in the container box 50 in a row in the left-right direction. The container 60 near the center, i.e., the right side, in the left-right direction of the washing machine 1 is referred to as a first container 601, and the container 60 near the side, i.e., the left side, in the left-right direction of the washing machine 1 is referred to as a second container 602. The first container 601 and the second container 602 are collectively referred to as the container 60 without distinction therebetween.

The front wall 51, the left and right side wall 52, and the back wall 53 are formed: a peripheral wall portion of the container box 50 surrounding the plurality of containers 60 in the horizontal direction. The front wall 51 of the container 50 is formed with: the number of windows 511 is two in this case, which corresponds to the number of containers 60. The window 511 is formed as: a part of the front wall portion 51 is penetrated or cut out, thereby communicating the inside of the container box 50 with the outside. For example, a transparent or translucent member may be embedded in the window 511, or may not be embedded in the window 511. In the present embodiment, the member is not embedded in the window 511. In a state where a plurality of containers 60 are accommodated therein, the plurality of window portions 511 are provided at positions corresponding to the respective containers 60. The user can visually confirm the amount of the treatment agent stored in the container 60 in a state where the container box 50 and the container 60 are stored in the storage portion 41.

As shown in fig. 2, 3, 5, 8, and the like, the container 60 is formed of a rectangular hollow container long in the front-rear direction or the left-right direction, and can store a liquid treatment agent. In this case, the container 60 may be composed of a transparent or translucent member, such as a synthetic resin. In addition, in this case, the container 60 has a sufficient capacity to store the treating agent used in the washing operation a plurality of times. In this case, the capacity of the container 60 is not particularly limited, but is preferably set to at least about several hundred mL to 2L in consideration of convenience for the user.

In the case of the present embodiment, the automatic loading device 40 has 2 containers 60. In this case, one of the 2 containers 60 can store, for example, a detergent as a treating agent. In addition, the other of the 2 containers 60 is capable of storing a softener as a treatment agent. The capacities of the 2 containers 60 may be the same or different. In the present embodiment, the volumes of the containers 601 and 602 are different, and the volume of the first container 601 is set as follows: greater than the capacity of the second container 602. In this case, the user can store the treatment agent, for example, the detergent, which is used more frequently or in a larger amount per time in the first container 601.

The structure of the second container 602 is shown in fig. 8. The structure of the first container 601 is also substantially the same. As shown in fig. 8, 9, and the like, the container 60 includes: a container main body 61, a cover member 62, a suction pipe 63, a leak prevention valve 64, and a filter not shown. The container body 61 constitutes the outer shell of the container 60. The cover member 62 is formed in a substantially rectangular plate shape, and is detachably attached to the upper portion of the container main body 61 to close the opening 616. The suction pipe 63 sucks the treatment agent stored in the container body 61, and supplies the treatment agent to the supply pump 42 through the leakage prevention valve 64. The leakage prevention valve 64 prevents the treatment agent from being inadvertently discharged from the container main body 61. The filter, not shown, has the following functions: when the treatment agent is sucked into the supply pump 42 from the suction pipe 63, foreign matter such as dust contained in the treatment agent is trapped.

In the present embodiment, as shown in fig. 8, the container body 61 is formed in a rectangular parallelepiped shape as a whole, and includes a discharge port 611, a front surface portion 612, a side surface portion 613, a back surface portion 614, a bottom portion 615, and an opening 616. The front surface portion 612 constitutes the front surface of the container body 61. The side surface portion 613 constitutes a side surface of the container body 61. The rear surface 614 constitutes the rear surface of the container body 61. The front surface portion 612, the side surface portion 613, and the back surface portion 614 form the outer peripheral surface of the container 60. The bottom 615 constitutes the bottom surface of the container body 61. The opening 616 is an opening provided in an upper portion of the container body 61, that is, an opening surrounded by the front surface portion 612, the side surface portion 613, and the back surface portion 614, so that the inside of the container body 61 is exposed to the outside of the container body 61.

As shown in fig. 5, 7, 8, and the like, the discharge port 611 is provided at the insertion direction side end portion of the container body 61, which is the rear surface 614 in this case. The discharge port 611 communicates the inside of the container 60 with the outside. When the container 60 is inserted into the correct position of the housing 41, the pipe 421 is inserted into and connected to the discharge port 611. Thus, the treatment agent stored in the container 60 can flow out of the container 60 and the storage portion 41 through the pipe portion 421 penetrating the discharge port 611 and the communication hole 43.

As shown in fig. 8 and the like, the cover member 62 has: a cover member main body 621, a charging port 622, and an opening/closing cover 623. The cover member main body 621 constitutes the housing of the cover member 62. The cover main body 621 is formed in a substantially rectangular plate shape, and has a partial inlet 622. The inlet 622 is an opening through which the user can input the treatment agent when the treatment agent is stored in the container 60. In this case, the inlet 622 is provided in the cover main body 621 at a portion near the tip end portion, which is an end portion in the extraction direction. The opening/closing cover 623 is rotatably provided to the cover member main body 621 via a hinge portion, and opens and closes the inlet 622.

When the treatment agent is stored in the container 60, first, as shown in fig. 3, for example, the user pulls out the container 60 from the storage unit 41 for each container box 50. Next, the user opens the opening/closing cover 623 and inputs the treatment agent into the container 60 through the input port 622. The user puts a plurality of doses of the treatment agent, for example, the treatment agent into a position such that the liquid surface reaches a predetermined position, closes the opening/closing cover 623, and inserts the container 60 into the storage portion 41 again for each container 50. Further, the user can open the opening/closing cover 623 and input the treatment agent into the container 60 without completely extracting the container case 50 and the container 60 from the storage unit 41. Further, the user can detach the cover member 62 from the container body 61 and put the treating agent into the opening 616.

Fig. 9 is a longitudinal sectional view of the container 60 accommodated in the container box 50. Fig. 10 is a partial longitudinal sectional view showing a part of fig. 9 in an enlarged manner. The suction pipe 63 is connected to the discharge port 611 and extends vertically downward to the vicinity of the bottom 615 of the container body. The lower end portion of the suction pipe 63 is located at a position slightly spaced apart from the bottom 615 of the container body 61. The inner surface of the container body 61 of the bottom 615 is inclined with respect to the front-rear direction and the left-right direction. That is, the bottom 615 is slightly inclined in such a manner as to descend toward the rear. The bottom 615 is inclined in the left-right direction so as to descend toward a position facing the lower end of the suction pipe 63. Thus, the treatment agent easily flows to a position facing the lower end of the suction pipe 63.

The leakage prevention valve 64 is provided between the discharge port 611 and the suction pipe 63. The leakage prevention valve 64 has the following functions: when the container 60 is detached from the housing portion 41 and the discharge port 611 is not connected to the pipe portion 421, the treatment agent stored in the container body 61 is prevented from leaking out of the container body 61 through the discharge port 611. In the case where the pipe portion 421 is connected to the discharge port 611, the leakage prevention valve 64 opens a path between the discharge port 611 and the suction pipe 63. Thereby, the supply pump 42 can suck out the treatment agent stored in the container main body 61. On the other hand, when the pipe 421 is not connected to the discharge port 611, the leakage prevention valve 64 closes the path between the discharge port 611 and the suction pipe 63, thereby preventing the treatment agent in the container body 61 from flowing out from the discharge port 611.

In a state where the container 60 is accommodated in the accommodating portion 41 and the pipe 421 is connected to the discharge port 611, the supply pump 42 sucks a predetermined amount of the treatment agent from the container 60 and inputs the sucked treatment agent into the second water supply path 33. The washing machine 1 can operate the supply pump 42 during water injection in the washing step and the rinsing step of the washing operation, for example, and thereby can throw the treatment agent required for the washing operation into the water drum 11 along with the water flowing through the second water supply path 33. The supply pump 42 may be provided in the container 60 or in the housing portion 41.

The container 60 also has a guide 70. The guide portion 70 is provided on the outer surface of the container body 61 and covers at least the discharge port 611 from below. In this case, the guide portion 70 is provided on the outer surface of the rear surface 614, which is the wall portion on the insertion direction side of the container body 61. The guide portion 70 has the following functions: so that the treatment agent dropped from the discharge port 611 is collected at the 1-position portion and guided to the outside of the peripheral wall portion of the container box 50. When the tube 421 is pulled out from the discharge port 611 to release the connection with the discharge port 611 when the container box 50 and the container 60 are pulled out, a small amount of the treatment agent may remain between the discharge port 611 and the leakage prevention valve 64. The discharge port 611 is opened rearward in the insertion direction, and therefore, a small amount of the remaining treatment agent drops rearward. The guide 70 covers the discharge port 611 at least from below, and receives the dropped treatment agent from the discharge port 611 at one time.

As shown in fig. 8 and the like, the guide portion 70 has a bottom surface portion 71 and a side surface portion 72. The bottom surface portion 71 and the side surface portion 72 protrude from the rear surface portion 614 toward the rear direction, that is, the insertion direction. The bottom surface 71 is located below the discharge port 611 and forms a surface substantially perpendicular to the vertical direction. The side surface portions 72 extend upward from both end portions of the bottom surface portion 71, and from the left and right end portions at this time.

The bottom surface portion 71 is provided with: closer to the discharge port 611 than the bottom 615 of the container body 61. In the present embodiment, the discharge port 611 is located at: a position above the center of the container body 61 in the up-down direction is, for example, located at: the bottom surface portion 71 is located at a position about 75% of the height dimension of the container main body 61 with respect to the bottom portion 615: the center of the container body 61 in the up-down direction is located slightly above, for example, at: about 55% of the height dimension of the container body 61 relative to the bottom 615.

The position of the upper end portion of the side surface portion 72 is set as: at least above the height of the center of the discharge port 611. In the present embodiment, the position of the upper end portion of the side surface portion 72 substantially coincides with the height position of the center of the discharge port 611.

The bottom surface portion 71 has: a groove 73 formed to be recessed downward. The groove 73 is located: the bottom surface portion 71 extends along the insertion direction, i.e., the front-rear direction, at the center in the left-right direction, which is the direction perpendicular to the insertion direction. In this case, the position of the groove 73 is: such that the center line of the discharge port 611 is on a line extending downward.

The upper surface of the bottom surface portion 71, that is, the surface facing the discharge port 611: an inclined surface which slightly descends toward the rear. The tilt angle may be set in a range of about 0.5 ° to about 2 °. In the present embodiment, the inclination angle of the upper surface of the bottom surface portion 71 is set to about 1 °. Further, the portion of the surface of the groove 73 facing the discharge port 611, which has the greatest degree of concavity, forms an inclined surface that slightly decreases rearward. The tilt angle may be set in the range of about 2.5 deg. to about 3.5 deg.. In the present embodiment, the inclination angle of the portion of the groove 73 where the degree of dishing is greatest is set to about 3 °.

The protruding length of the bottom surface portion 71 and the side surface portion 72 with respect to the back surface portion 614, that is, the insertion/extraction direction of the bottom surface portion 71 and the side surface portion 72, and the depth dimension in the front-rear direction at this time may be set to, for example, 3mm or more. In the present embodiment, the depth dimension of the side surface portion 72 is set to 5mm. In the present embodiment, the rear surface 614 of the container body 61 is recessed below the discharge port 611 toward the inside of the container 60. Accordingly, the depth dimension of the bottom surface portion 71 in the insertion/extraction direction, i.e., in the front-rear direction at this time, is set to be deep at the center portion in the left-right direction below the discharge port 611, and is set to be shallow at both the left-right end portions. The depth dimension of the bottom surface portion 71 in the insertion/removal direction, i.e., the front-rear direction at this time, is set to, for example, 10mm at a deep position and 5mm at a shallow position.

In the present embodiment, the rear surface 614 of the container body 61 is recessed toward the inside of the container 60 below the discharge port 611, but the present invention is not limited thereto. In other embodiments, the back surface 614 of the container body 61 may be formed flat without being recessed below the discharge port 611.

As shown in fig. 5 to 7, 9, and the like, the container box 50 has a notch 531, a receiving portion 56, and a recess 57. Since the cutout 531 is formed by cutting out a part of the upper portion of the back wall 53, a part of the upper end of the back wall 53 is recessed downward. The receiving portion 56 is formed as: a container shape protruding rearward from the back wall 53 and having an upper portion opened. The recess 57 is formed: in order to make a part of the back wall portion 53 in the left-right direction slightly concave toward the container 60, that is, toward the inside of the container box 50.

The notch 531 is provided at a position corresponding to the guide portion 70 in a state where the container 60 is accommodated in the container box 50 in the back wall portion 53. That is, the notch 531 is arranged as seen from the back side: the guide portion 70 is surrounded from the left, right and lower sides and is accommodated inside. Accordingly, the guide portions 70 and the discharge ports 611 of the containers 601 and 602 are exposed toward the rear surface side of the container box 50.

The receiving portion 56 is located below the back wall portion 53, that is, below the notch portion 531. The receiving portion 56 includes: left and right side surfaces 561, back surface 562, bottom surface 563, and upper opening 564. The front surface of the container shape of the receiving portion 56 is formed by a part of the back wall portion 53. The position of the upper opening 564 in the up-down direction is set as follows: the same as or lower than the position of the bottom of the concave portion of the notch 531 in the up-down direction. For example, in the present embodiment, the position of the upper opening 564 in the up-down direction is set as: lower than the bottom of the recess of the notch 531 in the vertical direction.

A space is formed between the back wall portion 53 of the container 50 and the back surface portion 412 of the housing portion 41. As shown in fig. 4, the housing portion 41 has a recess 413. A recess 413 is formed by recessing a part of the back surface 412 toward the rear. The recess 413 is located: the lower portion of the back surface portion 412 is below the communication hole 43. In a state where the container 50 is accommodated in the accommodating portion 41, the recess 413 accommodates the receiving portion 56 therein.

The receiving portion 56 is located: at least a part of the notch 531 and at least a part of each guide 70 are extended downward in rear view. Regarding the width dimension of the receiving portion 56 in the right-left direction, which is the direction perpendicular to the insertion/extraction direction, at least from the right end of the discharge port 611 of the first container 601 to the left end of the discharge port 611 of the second container 602 is set. In the present embodiment, the right side surface portion 561 of the receiving portion 56 is located in the left-right direction: a left side surface portion 561 of the receiving portion 56 is located between the right side surface portion 72 of the guide portion 70 of the first container 601 and the right end of the discharge port 611 of the first container 601 in the left-right direction: the left side surface portion 72 of the guide portion 70 of the second container 602 is located between the left end of the discharge port 611 of the second container 602. Further, the receiving portion 56 may be formed over the entire width of the back wall portion 53 in the lateral direction, and as in the present embodiment, by forming the receiving portion in a part of the width of the back wall portion 53, the space on the side of the compressed supply pump 42 can be suppressed, and further, the size of the washing machine 1 can be suppressed from being increased.

As shown in fig. 5 to 7, a recess 57 is formed in: the cutout portion 531 in the back wall portion 53 is located. A plurality of, and in this case, two concave portions 57 are formed, and each concave portion 57 is formed in: the container 60 is accommodated in the container box 50 at a position corresponding to each guide portion 70. That is, each concave portion 57 is provided in the rear view: such that each guide portion 70 extends downward. In the rear view, the position of the center of each concave portion 57 in the left-right direction coincides with the positions of the centers of each guide portion 70 and each discharge port 611. The recess 57 is formed at least in the upper end portion of the back wall portion 53, that is, in the portion of the bottom of the recess in which the notch 531 is formed. In the present embodiment, the recess 57 is formed throughout the entire vertical direction of the back wall portion 53, that is, in this case, from the bottom of the recess of the cutout portion 531 to the portion where the back wall portion 53 and the bottom surface portion 54 are connected.

The depth of the recess 57, that is, the length dimension in the anterior-posterior direction at this time, may be set in a range of, for example, about 1mm to about 10mm at the deepest position. In the present embodiment, the recess depth in the front-rear direction of the recess 57 is set to about 3mm at the deepest position.

At least a part of the guide portion 70 overlaps the back wall portion 53 in the up-down direction. In this case, at least a part of the guide portion 70 overlaps the recess 57 in the up-down direction. The front end portion on the insertion direction side of the bottom surface portion 71, that is, the rear end portion 711 at this time, protrudes rearward in the insertion direction, that is, in comparison with the recess 57, and overlaps the receiving portion 56 in the up-down direction. Therefore, the treatment agent dropped from the discharge port 611 to the guide portion 70 is not guided to the peripheral wall portion of the container box 50, that is, the space for accommodating the container 60, but is guided to the receiving portion 56, that is, the outer side of the peripheral wall portion.

Next, the functions of the guide 70, the receiving portion 56, and the like when the container box 50 and the container 60 are drawn out from the housing portion 41 will be described with reference to fig. 11 to 14. Fig. 11 shows: the structure surrounding the container 60 and the container box 50 is provided during the process of extracting the container from the container 41. Fig. 12 to 14 show: a cross-sectional view taken along line III-III of fig. 11. Fig. 12 shows: the container 60 and the container case 50 are accommodated in the accommodating portion 41. Fig. 13 shows: the container 60 and the container box 50 are slightly pulled out from the housing portion 41. Fig. 14 shows: the container 60 and the container box 50 are further pulled out from the housing portion 41. In fig. 12 to 14, the suction pipe 63 and the leakage prevention valve 64 are omitted.

In the state shown in fig. 12, the discharge port 611 is connected to the pipe portion 421, and the treatment agent does not leak from the discharge port 611 to the outside nor from the pipe portion 421 due to the action of the leakage prevention valve 64 or the like. In this state, the back wall 53 of the case 50 and the back surface 412 of the housing 41 are not in contact with each other, and a space is formed between the back wall 53 and the back surface 412. As shown in fig. 13, when the container box 50 and the container 60 are moved forward in the extraction direction, that is, at this time, by the extraction operation of the user, the connection between the discharge port 611 and the pipe 421 is released, and the tip end of the pipe 421 is released from the discharge port 611. At this time, a part of the treatment agent remaining between the discharge port 611 and the leakage prevention valve 64 may be discharged from the discharge port 611 to the outside of the container 60. In addition, a part of the treatment agent remaining inside the tube 421 may be discharged to the outside from the tip end portion on the extraction direction side of the tube 421, that is, the tip end portion.

The treatment agent discharged from the discharge port 611 drops to the bottom surface portion 71 of the guide portion 70. Immediately after the container box 50 starts to be drawn out, the pipe 421 is located above the guide 70, and therefore, the treatment agent discharged from the pipe 421 also drops to the guide 70. The treatment agent dropped onto the bottom surface portion 71 of the guide portion 70 flows rearward along the slope of the bottom surface portion 71 while being collected in the groove portion 73. The treatment agent that has flowed and dropped from the rear end 711 of the bottom surface 71 is received by the receiving portion 56.

As shown in fig. 14, when the container 50 is further pulled out, the front end of the pipe 421 moves backward relative to the guide 70, and the treatment agent discharged from the front end of the pipe 421 drops directly into the receiving portion 56 at a position above the receiving portion 56. As a result, the container box 50 and the container 60 are extracted from the storage unit 41, and the treatment agent discharged from the discharge port 611 and/or the distal end portion of the pipe 421 is received by the receiving unit 56 and accumulated in the receiving unit 56.

In a state where the container 50 and the container 60 are inserted into the housing portion 41 again, as described above, a space is formed between the back wall portion 53 of the container 50 and the back surface portion 412 of the housing portion 41. Therefore, even if the treating agent adheres to the rear surface of the back wall 53, the possibility of the treating agent adhering to the back surface 412 and soiling the storage portion 41 can be suppressed.

Here, a case where the guide portion 70 is not provided in the container 60 will be studied. In this case, when the container 60 and the container case 50 are drawn out from the housing portion 41, the treatment agent may drip into the container case 50 from the discharge port 611, and the treatment agent may accumulate in the container case 50. In addition, the treatment agent in the process of dripping from the discharge port 611 and the treatment agent stored in the container box 50 may adhere to the outer peripheral surface of the container 60. Therefore, the user is required to detach the container 60 and clean the container box 50 or the container. The container box 50 has a certain area for housing the container 60 therein, and there is a possibility that the treating agent may spread widely inside. In addition, the lower portion of the container 60 and the inside of the container box 50 may be formed in a concave-convex shape in order to fix the container 60 to the container box 50, and in this case, the cleaning operation of the automatic loading device 40 including the container 60 and the container box 50 is not easy.

In contrast, according to the present embodiment described above, the washing machine 1 includes the water drum 11 and the automatic loading device 40. The water drum 11 accommodates laundry therein. The automatic input device 40 includes: a predetermined amount of the treating agent is automatically introduced into the water drum 11. The automatic input device 40 includes: container 60, container case 50, and housing 41. The container 60 is configured to: the treatment agent can be stored in an amount for a plurality of washing operations. The container box 50 has: the container 60 is accommodated in the front wall 51, the left and right side walls 52, and the back wall 53, which are peripheral wall portions. The housing 41 houses the container 50 so that the container 50 can be pulled out. The container 60 has: the discharge port 611 and the guide portion 70. The discharge port 611 is: the openings provided in the front surface portion 612, the side surface portion 613, or the rear surface portion 614, which are the outer peripheral surfaces, of the container 60 are configured as follows: the treatment agent stored in the container 60 can be discharged to the outside of the container 60 by communicating the inside of the container 60 with the outside. The guide portion 70 is provided on a front surface portion 612, a side surface portion 613, and a rear surface portion 614, which are outer peripheral surfaces of the container 60, covers at least the discharge port 611 from below, and extends to the outside of the front wall portion 51, the left and right side wall portions 52, and the rear wall portion 53, which are peripheral wall portions, of the container 50. In the present embodiment, the guide portion 70 is provided in: the surface in the insertion direction of the outer peripheral surface of the container 60, that is, the rear surface 614 of the container extends rearward than the surface in the insertion direction of the peripheral wall of the container case 50, that is, the rear wall 53.

This can prevent the treatment agent dropped from the discharge port 611 from being scattered into the container box 50. Therefore, the treatment agent is prevented from accumulating in the container box 50 and adhering to the outer peripheral surface of the container 60. Therefore, the user can save the effort of cleaning the outer peripheral surface of the container 60 and the inside of the container box 50 having a large area. Accordingly, the washing machine 1 in which the automatic loading device 40 is easily cleaned can be provided.

The guide portion 70 includes: a bottom surface portion 71 and left and right side surface portions 72, and the bottom surface portion 71 includes: a groove 73 formed to be recessed downward and extending in the insertion/removal direction of the cartridge 50. In the present embodiment, the groove 73 extends in the front-rear direction.

As a result, the liquid such as the treatment agent dropped onto the guide portion 70 is stored in the groove 73, and thus the discharge from one place to the outside of the container box 50 can be promoted. Therefore, the treatment agent can be collected at one place, and therefore, the treatment agent does not spread around and the cleaning work is easier than the case where the treatment agent is discharged from a wide area of the guide portion 70 to the outside of the container 50.

The container box 50 has: the container 60 is housed in the container case 50, and is formed as a container-shaped receiving portion 56 on the surface facing the guide portion 70 of the peripheral wall portion, that is, on the outer side of the back wall portion 53 and below the guide portion 70.

This can prevent the treating agent from dripping into the storage portion 41. In addition, when the container 60 is detached from the container box 50, the user is hard to see the accumulated liquid, and thus, the user is not given a bad impression such as uncleanness.

In the present embodiment, the groove 73 is formed from the front end to the rear end 711 of the bottom surface 71 of the guide 70, which is the position forward of the discharge port 611, but the present invention is not limited thereto. For example, in other embodiments, the groove 73 may be formed from at least a position vertically below the discharge port 611 toward the rear end 711 of the bottom surface 71.

The washing machine 1 includes: the pump 42 and the pipe 421 are supplied. The supply pump 42 has: a function of sucking out a predetermined amount of the treating agent from the container 60 and supplying the same to the water drum 11. The pipe 421 extends from the supply pump 42 toward the container 60, and is connected to the discharge port 611. The receiving portion 56 is provided below the tube portion 421 in a state where the container box 50 is accommodated in the accommodating portion 41, and is a position where at least a part thereof overlaps the tube portion 421 in a plan view. That is, the receiving portion 56 and the pipe portion 421 overlap each other at least partially in the vertical direction in a state where the container box 50 is accommodated in the accommodating portion 41.

Accordingly, the receiving portion 56 can receive the treatment agent dropped from the tip end of the pipe portion 421 of the supply pump 42 in addition to the treatment agent dropped from the guide portion 70. Therefore, the dripping of the treatment agent into the housing portion 41 can be further suppressed.

Here, in the case where the washing machine 1 includes a plurality of containers 60, if a plurality of receiving portions 56 are provided corresponding to the respective containers 60, the structure of the casing 50 may become complicated, and the process of forming and cleaning the casing 50 may become complicated.

In contrast, the washing machine 1 includes: a plurality of containers 601 and 602 arranged in a direction orthogonal to the insertion and removal direction of the container box 50. The receiving portion 56 is formed at least over a width from the discharge port 611 of one container such as the first container 601 to the discharge port 611 of the other container such as the second container 602 among the plurality of containers 601, 602.

Accordingly, the number of receiving portions 56 corresponding to the plurality of containers 601 and 602 is 1, and the structure of the container box 50 can be simplified. As a result, the molding operation and cleaning operation of the container 50 can be simplified and facilitated.

The back wall portion 53, which is a surface in contact with the receiving portion 56, of the front wall portion 51, the side wall portion 52, and the back wall portion 53 of the container 50 is provided with: a recess 57 located below the guide 70 and formed to be recessed toward the container 60.

This increases the distance by which the rear end 711 of the guide 70 overlaps the receiving portion 56. Therefore, the discharge of the treatment agent from the guide portion 70 to the space other than the interior of the receiving portion 56 can be suppressed.

(second embodiment)

The second embodiment will be described with reference to fig. 15. In the present embodiment, the washing machine 1 includes: one or more, and in this case two, containers 80 are substituted for the container 60. In addition, the washing machine 1 does not include the container box 50 and the recess 413. That is, the container 80 is directly accommodated in the accommodating portion 41 in a extractable manner. In addition, the container 80 has a recess 90.

The front surface portion 612 constitutes the front surface of the container body 61. The front surface portion 812 constitutes the front surface of the container body 81. The side surface portion 813 constitutes a side surface of the container body 81. The rear surface portion 814 constitutes the rear surface of the container body 81. The bottom 815 constitutes the bottom surface of the container body 81. The opening 816 is an opening provided in an upper portion of the container body 81, that is, an opening surrounded by the front surface portion 812, the side surface portion 813, and the back surface portion 814, so that the inside of the container body 81 is exposed to the outside of the container body 81.

The discharge port 811 is: is provided at the insertion direction side end surface of the container 80, that is, at the opening of the rear surface 814 at this time. The discharge port 811 communicates the inside of the container 80 with the outside. When the container 80 is inserted into the correct position of the housing 41, the tube 421 is inserted into and connected to the outlet 811. Thus, the treatment agent stored in the container 80 can flow out of the container 80 and the housing portion 41 through the pipe portion 421 penetrating the discharge port 811 and the communication hole 43.

In this case, a part of the back surface portion 814 is recessed toward the inside of the container body 81 to form the concave portion 90. The recess 90 is open at the rear portion, which is the insertion direction side of the container 80, and includes: front surface 91, right and left side surfaces 92, bottom surface 93, upper surface 94, and rear opening 95. A discharge port 811 is formed in an upper portion of the front surface portion 91. A rising portion 96 is formed at a lower end portion of the rear opening 95. The rising portion 96 is formed as: protruding upward from the bottom surface 93. Thus, the lower end of the rear opening 95 is located: and above the lower end of the front surface portion 91. That is, the recess 90 has a receiving portion 97 at a lower portion. The receiving portion 97 is formed as: a container shape capable of storing the treating agent therein. In addition, the raised portion 96 is on the same plane, i.e., coplanar, as the un-recessed face of the back face portion 814.

The discharge port 811 is formed in a tubular shape and slightly protrudes from the front surface portion 91 toward the rear, which is the insertion direction of the container 80. The insertion direction side front end portion, i.e., the rear end portion of the discharge port 811 is located at: the front side is the extraction direction side of the rising portion 96. That is, the rear end portion of the discharge port 811 is located: the rear end of the receiving portion 97 is located further toward the front side. In the present embodiment, the discharge port 811 is formed in a tubular shape and slightly protrudes from the front surface portion 91 toward the rear, which is the insertion direction of the container 80, but is not limited thereto. For example, in other embodiments, the rear end of the discharge port 811 may be on the same plane as the front surface portion 91, i.e., coplanar.

The case where the container 80 is drawn out from the housing portion 41 will be described. When the container 80 moves forward in the extraction direction, that is, at this time, the connection between the discharge port 811 and the pipe 421 is released, and the distal end of the pipe 421 is released from the discharge port 811. The treatment agent discharged from the discharge port 811 drops to the bottom surface portion 93 of the recess 90. Immediately after the container box 50 starts to be pulled out, the tube 421 is positioned above the recess 90, and therefore, the treatment agent discharged from the tube 421 also drops to the bottom surface 93. The treating agent dropped onto the bottom surface 93 is received by the rising portion 96 and stored in: the receiving portion 97 provided on the outer peripheral portion of the container 80 is provided therein.

According to the present embodiment described above, the washing machine 1 includes the water drum 11 and the automatic loading device 40. The water drum 11 accommodates laundry therein.

The automatic loading device 40 has a container 80 and a housing portion 41. The container 80 is configured to: the treatment agent can be stored in an amount for a plurality of washing operations. The housing 41 houses the container 80 in a extractable manner. The container 80 has a discharge port 811 and a receiving portion 97. The discharge port 811 is: the opening provided in the front surface portion 812, the side surface portion 813, or the back surface portion 814, which is the outer peripheral surface, of the container 80 is configured to: the inside of the container 80 is communicated with the outside, and the treatment agent stored in the container 80 can be discharged to the outside of the container 80. The receiving portion 97 is formed in a container shape below the discharge port 811 on a front surface portion 812, a side surface portion 813, or a back surface portion 814, which are outer peripheral portions, of the container 80. The rising portion 96, which is the insertion direction side end surface of the receiving portion 97, is located: the insertion direction side end of the discharge port 811 is located closer to the insertion direction side. In the present embodiment, the rising portion 96, which is the rear end surface of the receiving portion 97, is located at: and a position further rearward than the rear end portion of the discharge port 811.

Accordingly, in the structure in which the container 80 is directly inserted into and removed from the housing 41 without the container case, the receiving portion 97 is provided in the container 80. This can collect the treatment agent that drips from the discharge port 811 and the pipe 421 to the receiving portion, and therefore, the treatment agent can be prevented from adhering to the portions other than the receiving portion 97 of the container and the inside of the housing portion 41. Therefore, according to this configuration, it is also possible to provide the washing machine 1 in which cleaning of the automatic loading device is easily performed.

In the above-described embodiments, the washing machine 1 includes the two containers 601 and 602, but is not limited thereto.
